Kinds of Prednisolone Terms modified by Prednisolone Selected AbstractsHemicrania Continua Responsive to Intravenous Methyl PrednisoloneHEADACHE, Issue 4 2009Sanjay Prakash DM Hemicrania continua (HC) is a strictly unilateral, continuous primary headache disorder with periodic exacerbations, usually accompanied by cranial autonomic disturbances. Exquisite and persistent effect of indomethacin is a fundamental property of HC. We report 2 patients of HC in which attacks were successfully eliminated by repeated infusion of methyl prednisolone. [source] In vivo analysis of gut function and disease changes in a zebrafish larvae model of inflammatory bowel disease: A feasibility studyINFLAMMATORY BOWEL DISEASES, Issue 7 2010Angeleen Fleming PhD Abstract Background: The aim of this study was to develop a model of inflammatory bowel disease (IBD) in zebrafish larvae, together with a method for the rapid assessment of gut morphology and function in vivo thereby enabling medium-throughput compound screening. Methods: Assays were performed using larval zebrafish from 3,8 days postfertilization (d.p.f.) in 96-well plates. Gut morphology and peristalsis were observed in vivo using fluorescent imaging following ingestion of fluorescent dyes. IBD was induced by addition of 2,4,6-trinitrobenzenesulfonic acid (TNBS) to the medium within the well. Pathology was assessed in vivo using fluorescent imaging and postmortem by histology, immunohistochemistry, and electron microscopy. Therapeutic compounds were evaluated by coadministration with TNBS. Results: A novel method of investigating gut architecture and peristalsis was devised using fluorescent imaging of live zebrafish larvae. Archetypal changes in gut architecture consistent with colitis were observed throughout the gut. Significant changes in goblet cell number and tumor necrosis factor alpha (TNF-,) antibody staining were used to quantify disease severity and rescue. Prednisolone and 5-amino salicylic acid treatment ameliorated the disease changes. Candidate therapeutic compounds (NOS inhibitors, thalidomide, and parthenolide) were assessed and a dissociation was observed between efficacy assessed using a single biochemical measure (TNF-, staining) versus an assessment of the entire disease state. Conclusions: Gut physiology and pathology relevant to human disease state can be rapidly modeled in zebrafish larvae. The model is suitable for medium-throughput chemical screens and is amenable to genetic manipulation, hence offers a powerful novel premammalian adjunct to the study of gastrointestinal disease. (Inflamm Bowel Dis 2010) [source] Acute febrile neutrophilic dermatosis (Sweet's syndrome) with nodular episcleritis and polyneuropathyINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2002Taizo Kato MD A 56-year-old Japanese housewife presented with multiple erythematous lesions in association with ocular hyperemia and pain in the right upper and lower extremities, including the hands and feet. These symptoms were preceded by a sore throat with persistent fever higher than 38.5 °C for about 1 week. Dermatologic examination showed tender, dull-red, erythematous lesions, measuring 1,2 cm in diameter, located predominantly on the forehead, cheeks, auricular region, neck, forearm, hands, and feet. A biopsy specimen obtained from an erythematous lesion on the right forearm revealed prominent edema in the papillary dermis and remarkable inflammatory cell infiltration throughout the entire dermis (Fig. 1). The infiltrate predominantly consisted of neutrophils and nuclear dust without signs of vasculitis. In routine examination, the leukocyte count was 15,000/mL (normal range, 4000,8000/mL) with severe neutrophilia (80%). The C-reactive protein (CRP) level was 17.65 mg/dL (normal range, < 0.5 mg/dL) and the anti-streptolysin (ASLO) level was 611 IU/mL (normal range, < 166 IU/mL). In human leukocyte antigen (HLA) testing, HLA-A2, -B39, -B35, -Cw2, and -Cw7 were positive, and HLA-B51, -B54, and -Cw1 were negative. Figure Figure 1 . Histologic picture showing a dermal infiltrate of neutrophils Ocular hyperemia was caused by episcleritis forming a nodule and surrounding congestion of the superficial episcleritic vessels at the central portion of the sclera (Fig. 2). The patient suffered from pain once an hour, continuing for about 3 min, at the lateral portion of the right upper and lower extremities, as well as the right small finger. Neurologic examination demonstrated moderate or slight muscle weakness in the extremities. Hand grasping powers were 9 and 7 kg on the right and left, respectively. The patient was right-handed. Dysesthesia and paresthesia were also observed on the hands and feet. The deep tendon reflexes were preserved, however, even in the distal portion of the upper and lower limbs. In addition, essential tremor localized to the neck was recognized. Magnetic resonance imaging did not show any episodes of transient abnormal signal intensity in the central nervous system. Figure 2. Nodular episcleritis (right eye). Telangiectasia of winding vessels with nodular elevation was observed at the upper portion of the sclera The patient was treated with prednisolone (initial dose of 30 mg/day) and intravenous injection of cefazolin sodium (2 g/day for 5 days). Almost complete regression of the ocular and neurologic manifestations, as well as the skin lesions, was achieved in 2 weeks. Prednisolone was reduced gradually and suspended after 4 weeks. Leukocyte and neutrophil counts, CRP, and ASO returned to normal on suspension of therapy. Slight paresthesia remained in the right small finger even after stopping steroid. There was no recurrence at follow-up 6 months later. [source] Biowaiver monographs for immediate release solid oral dosage forms: Prednisolone,,JOURNAL OF PHARMACEUTICAL SCIENCES, Issue 1 2007M. Vogt Abstract Literature data relevant to the decision to allow a waiver of in vivo bioequivalence (BE) testing for the approval of immediate release (IR) solid oral dosage forms containing prednisolone are reviewed. Data on its solubility, oral absorption, and permeability are not totally conclusive, but strongly suggest a BCS Class 1 classification. Prednisolone's therapeutic indications and therapeutic index, pharmacokinetics, and the possibility of excipient interactions were also taken into consideration. Available evidence indicates that a biowaiver for IR solid oral dosage forms formulated with the excipients tabulated in this article would be unlikely to expose patients to undue risks. © 2006 Wiley-Liss, Inc. and the American Pharmacists Association J Pharm Sci 96:27,37, 2007 [source] Pharmacodynamic interaction of recombinant human interleukin-10 and prednisolone using in vitro whole blood lymphocyte proliferationJOURNAL OF PHARMACEUTICAL SCIENCES, Issue 5 2002Abhijit Chakraborty Abstract Prednisolone, a commonly used synthetic corticosteroid, and IL-10, a cytokine under investigation for strong antiinflammatory properties, are being contemplated as a potential joint therapeutic regimen in immune disorders. Their pharmacodynamic interactions were examined in blood from healthy adult male and female volunteers using an in vitro phytohemagglutinin (PHA)-stimulated whole,blood lymphocyte proliferation technique. Isobolograms along with parametric competitive and noncompetitive interaction models were used to determine the nature and intensity of interactions. Single drug effects show prednisolone more efficacious in inhibiting lymphocyte proliferation with an IC50 of 3.3 ng/mL and Imax value of 1, signifying complete suppression. Analogous parameters for IL-10 were 16.2 ng/mL for IC50 and 0.89 for Imax. There were no significant differences in the single drug immunosuppressive effects among genders. Their joint effects showed additive interaction based on isobolographic analysis. Parametric analysis using the competitive interaction model described their interaction as slightly synergistic, while the noncompetitive interaction modeling indicate a small degree of antagonism. Also, the joint effects in females tend to be more antagonistic than males. Concomitant use of prednisolone and IL-10 should thus reflect the net additive responses to concentrations of each agent. © 2002 Wiley-Liss, Inc. and the American Pharmaceutical Association J Pharm Sci 91:1334,1342, 2002 [source] Chemotherapy with Cyclophosphamide, Vincristine, and Prednisolone (COP) in Cats with Malignant Lymphoma: New Results with an Old ProtocolJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 2 2002Erik Teske This retrospective study in 61 cats with malignant lymphomas examined the efficacy of a well-established chemotherapy protocol (cyclophosphamide, vincristine, and prednisolone [COP]) in the Netherlands, a country with a low prevalence of feline leukemia virus (FeLV). Twenty-two cats (36.1%) had mediastinal lymphoma, 11 (18.0%) had alimentary lymphoma, 7 (11.5%) had peripheral lymphoma, 8 (13.1%) had nasal lymphoma, and 13 (21.3%) had miscellaneous lymphoma (including renal lymphoma in 2 [3.3%]). Of the 54 cats that were tested, only 4 (7.4%) were FeLV positive. Complete remission (CR) was achieved in 46 of the 61 cats (75.4%). The estimated 1- and 2-year disease-free periods (DFPs) in the 46 cats with CR were 51.4 and 37.8%, respectively, whereas the median duration of remission was 251 days. The overall estimated 1-year survival rate in all cats was 48.7%, and the 2-year survival rate was 39.9%, with a median survival of 266 days. The median survival time and the 1-year survival rate for mediastinal lymphoma were 262 days and 49.4%, respectively. Siamese cats had a more favorable prognosis for survival and remission than other breeds. Response to therapy in this study was shown to be a significant prognostic indicator. CR is necessary for long-term survival. Cats that did not achieve CR had little chance of survival for longer than 1 year. Young Siamese cats in this study had a greater tendency to develop mediastinal malignant lymphoma at a young age, and all were FeLV negative. In comparison with results reported in other studies with different combination chemotherapy protocols, these are among the highest percentages of remission and the longest survival rates for cats with malignant lymphoma. [source] Efficacy of prednisolone in children hospitalized for recurrent wheezingPEDIATRIC ALLERGY AND IMMUNOLOGY, Issue 4 2007Tuomas Jartti Data on the efficacy of corticosteroids on respiratory picornavirus-induced wheezing are limited. To determine whether prednisolone is effective in rhinovirus- or enterovirus-induced recurrent wheezing, we conducted a controlled trial comparing oral prednisolone (2 mg/kg/day in three divided doses for 3 days) with placebo in hospitalized wheezing children and studied post hoc virus-specific efficacy in early wheezing (<3 episodes, reported elsewhere) and in recurrent wheezing (,3 episodes). Virus-negative children where excluded. Our primary endpoint was the time until children were ready for discharge. Secondary endpoints included oxygen saturation and exhaled nitric oxide during hospitalization, duration of symptoms, blood eosinophil count, and impulse oscillometry 2 wk after discharge, and occurrence of relapses during the following 2 months. Virus-specific effects were analyzed with interaction analysis in a multivariate regression model. During the study period, 661 patients were hospitalized, 293 randomized, and 59 were accepted in this analysis (mean age 2.6 yr, s.d. 1.3). Prednisolone did not significantly decrease the time until ready for discharge in all patients (prednisolone vs. placebo, medians, 18 vs. 24 h, p = 0.11). However, prednisolone decreased the time until ready for discharge in children with picornavirus infection (respectively, 12 vs. 24 h, p = 0.0022) and more specifically, in children with enterovirus infection (6 vs. 35 h, p = 0.0007). In the secondary endpoints, prednisolone decreased the duration of cough and dyspnea in rhinovirus-affected children (p = 0.033 for both). Prospectively designed clinical trial is needed to test the hypothesis that prednisolone reduces symptoms in picornavirus-affected wheezing children. [source] Prednisolone Suppresses the Function and Promotes Apoptosis of Plasmacytoid Dendritic CellsAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2006P. P. C. Boor Organ transplant recipients are highly susceptible to viral infections early after transplantation. Plasmacytoid dendritic cells (PDC) play a major role in antiviral immunity. Therefore, we determined the numbers of circulating PDC after liver transplantation (LTX) and established the effects of immunosuppressive drugs on PDC survival and function. PDC were determined longitudinally in 13 LTX recipients treated with prednisone and cyclosporin or tacrolimus. Purified PDC were cultured with or without clinically relevant concentrations of cyclosporin, tacrolimus or prednisolone. Apoptosis induction was monitored by determination of active caspase-3, nuclear condensation and annexin-V/7AAD staining. After LTX, a 4-fold reduction in the number of circulating PDC was observed (p < 0.01), which recovered partially after discontinuation of prednisone treatment. In vitro, prednisolone induced apoptosis in PDC, while cyclosporin and tacrolimus did not. Higher doses of prednisolone were needed to induce apoptosis in Toll-like receptor (TLR)-stimulated PDC. However, non-apoptosis inducing concentrations of prednisolone suppressed interferon-alpha production, upregulation of co-stimulatory molecules and allo-stimulatory capacity of TLR-stimulated PDC. In conclusion, prednisolone induces apoptosis in PDC, which explains the decline in circulating PDC numbers after transplantation. Moreover, prednisolone suppresses the functions of TLR-stimulated PDC. Therefore, corticosteroid-free immunosuppressive therapy may reduce the number and severity of viral infections after transplantation. [source] Treatment of Parthenium dermatitis with methotrexateCONTACT DERMATITIS, Issue 2 2007Vinod K. Sharma Patients with parthenium dermatitis are often unresponsive to topical steroids, and immunosuppressive agents may be necessary to reduce their need for systemic corticosteroids. We evaluated the efficacy of methotrexate in parthenium dermatitis. Sixteen patients unresponsive to topical treatment were included after baseline investigations, and treated with oral methotrexate (15 mg/week). Clinical response was monitored using a dermatitis area and severity index (DASI). Seven patients completed ,6 months' follow-up, and their mean DASI fell to 5, 2.7 and 2.1 at the end of 1, 3 and 6 months respectively, from a baseline score of 10. Only 3/7 patients required oral prednisolone in the initial 2,4 weeks. Side effects were minor, being mainly folliculitis and furuncles. Methotrexate may hence be a useful alternative for patients with severe parthenium dermatitis. [source] Case of eosinophilic granulomatous enterocolitis caused by Strongyloides stercoralis infection with marked hypoalbuminemia and ascitesDIGESTIVE ENDOSCOPY, Issue 3 2004Nuthapong Ukarapol We report a 10-year-old boy presenting with generalized pitting edema, ascites, abdominal pain, and chronic mucous diarrhea for 4 weeks. He had underlying diseases of hemoglobin E and juvenile rheumatoid arthritis and had been treated with immunosuppressive agents for a long period of time, including prednisolone and methotrexate. After extensive investigations, Strongyloides stercoralis infection, leading to protein-losing enteropathy and eosinophilic granulomatous enterocolitis, was diagnosed. In the present report, we demonstrate early colonoscopic findings, revealing patchy erythema and small raised mucosal nodules with erosions at the cecum. Histopathological study showed open ulceration with cryptitis, intense infiltration of eosinophils and histiocytes with granuloma formation, in which Strongyloides stercoralis larvae were noted. [source] The effects of dexamethasone and prednisolone on pituitary and ovarian function in the mareEQUINE VETERINARY JOURNAL, Issue 5 2010R. A. FERRIS Summary Reasons for performing study: Persistent mating induced endometritis is among the most common causes of infertility in the mare. Recently, improved pregnancy rates have been reported when corticosteroids were administered to ,problem mares' specifically, to modulate the post mating inflammatory response; however, the effect of treatment on pituitary and ovarian function requires further study. Objectives: To evaluate the effects of prolonged treatment with glucocorticoids on pituitary and ovarian function. Methods: Eighteen cycling Quarter Horse mares in early oestrus were assigned randomly to one of 3 treatment groups: dexamethasone 0.05 mg/kg bwt i.v. twice a day, prednisolone 0.5 mg/kg per os twice a day, or placebo for 5 days. Mares were examined by ultrasound daily to evaluate reproductive function. Blood samples were collected daily to measure luteinising hormone (LH), progesterone and cortisol levels. Results: Dexamethasone treatment caused greater (P<0.05) suppression of endogenous cortisol concentration (9.4 ± 1.1 ng/ml) compared to prednisolone- (41.9 ± 4.0 ng/ml) or placebo-treated mares (32.4 ± 3.8 ng/ml). After 24 h, mares treated with dexamethasone exhibited lower uterine oedema scores than prednisolone- or placebo-treated mares. An ovulation rate of 40% was observed in dexamethasone-treated mares (2/5) compared to 83% for prednisolone (5/6) and 100% for placebo-treated (6/6) mares. An absence of a LH surge was noted in 3 of 5 dexamethasone-treated mares and one of 6 prednisolone-treated mares. Conclusions: Repeated administration of dexamethasone to mares in oestrus is associated with decreased uterine oedema, suppression of LH and a high rate of ovulation failure. It is recommended that dexamethasone treatment is limited to only 1 or 2 days and that a lower dose is considered in the management of persistent mating induced endometritis to avoid potential adverse affects on reproductive function. [source] Fulminant hepatitis after allogenic bone marrow transplantation caused by reactivation of hepatitis B virus with gene mutations in the core promotor regionEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 3 2006Kiyoshi Kitano Abstract:, Under immunosuppressive conditions after hematopoietic stem cell transplantation (HSCT), even if hepatitis B virus (HBV) antigen is negative but hepatitis B surface antibody (HBsAb) or hepatitis B core antibody (HBcAb) is presented, HBV reactivates and sometimes causes fulminant hepatitis. However, it remains unclear which patients will develop fulminant hepatitis, or whether fulminant hepatitis is caused by host-related factors or by virus-related factors. A 30-yr-old man with a history of aplastic anemia since 3 yr of age underwent allogenic BMT, when HBsAb and HBcAb were positive but HBs antigen (HBsAg) was negative. The donor was negative for HBsAg, HBsAb and HBcAb. After transplantation, the patient was complicated by acute graft-vs.-host disease (GVHD), cytomegalovirus infection, intestinal thrombotic microangiopathy and aspergillus colitis. Chronic GVHD was well controlled by FK506 and prednisolone. Twenty months after transplantation, the patient was admitted with general fatigue and liver dysfunction and was found to be positive for HBsAg and HBeAg. His serum HBV-DNA level was >8.8 log of the genome equivalent (LGE)/mL. Therefore, he was diagnosed as having hepatitis B caused by HBV reactivation and 100 mg/d lamivudine treatment was started. However, jaundice and hepatic failure deteriorated and became fatal. On analysis of the HBV-DNA, two adjacent gene mutations in the core promoter region (T1762/A1764) were detected. Increased replication of the mutated HBV might have caused HBV reactivation which progressed to fulminant hepatitis. [source] Successful treatment of idiopathic thrombocytopenic purpura by Chinese herbal medicine EK-49 and ascorbic acid in an elderly patient developing chronic subdural hematomaGERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 1 2007Atsushi Hirano Treatment of idiopathic thrombocytopenic purpura can present difficult therapeutic choices. An 88-year-old woman was admitted for treatment of a right subdural hematoma. She had a history of chronic thrombocytopenia, with follow-up evaluations by a local physician. Platelet count on admission was 5 × 103/µL, with a high serum concentration of platelet-associated immunoglobulin G. Bone marrow examination showed a marked increase in megakaryocytes. The patient was diagnosed with idiopathic thrombocytopenic purpura accompanied by chronic subdural hematoma. An increase in platelet count and gradual resolution of the subdural hematoma were obtained with prednisolone and azathioprine administration, but platelet count decreased when steroid tapering was attempted. Ultimately we administered the Chinese herbal medicine EK-49 and ascorbic acid, with a gradual increase in platelet count and no adverse effects. Some elderly patients with chronic subdural hematoma can be treated non-invasively. Further, a combination of EK-49 and ascorbic acid may be an effective treatment for refractory idiopathic thrombocytopenic purpura. [source] Hemicrania Continua Responsive to Intravenous Methyl PrednisoloneHEADACHE, Issue 4 2009Sanjay Prakash DM Hemicrania continua (HC) is a strictly unilateral, continuous primary headache disorder with periodic exacerbations, usually accompanied by cranial autonomic disturbances. Exquisite and persistent effect of indomethacin is a fundamental property of HC. We report 2 patients of HC in which attacks were successfully eliminated by repeated infusion of methyl prednisolone. [source] Early change in bilirubin levels is an important prognostic factor in severe alcoholic hepatitis treated with prednisoloneHEPATOLOGY, Issue 6 2003Philippe Mathurin M.D. Early identification of patients with severe (discriminant function ,32) biopsy-proven alcoholic hepatitis (AH) who are not responding to corticosteroids would be clinically relevant. Our goal was to develop simple criteria that will help physicians to promptly identify nonresponders to corticosteroids. A total of 238 patients were included. We used 6 months survival as an end point because of the rule requiring 6 months for listing alcoholic patients for transplantation. Overall survival at 1 and 6 months was 85% ± 2.3% and 64.3% ± 3.3%, respectively. An early change in bilirubin levels (ECBL) at 7 days (defined as bilirubin level at 7 days lower than bilirubin level on the first day of treatment) was observed in 73% of patients. At 7 days, in patients with ECBL, bilirubin decreased (84 ± 75 ,mol/L [4.94 ± 4.40 mg/dL]), whereas it increased in patients without ECBL (76.5 ± 77 ,mol/L [4.50 ± 4.54 mg/dL], P < .0001). Ninety-five percent of patients with ECBL continued to have improved liver function during treatment. At 6 months, survival of patients with ECBL was significantly higher than that of patients without ECBL, 82.8% ± 3.3% versus 23% ± 5.8%, P < .0001. On multivariate analysis, ECBL, discriminant function and creatinine were independent prognostic variables, and ECBL had the most important prognostic value. In conclusion, ECBL is a very simple predictive factor for identifying nonresponders. A recommendation to discontinue corticosteroids after 7 days in patients without ECBL, suggested by our results, awaits additional confirmation. [source] Prednisolone Priming Enhances Th1 Response and Efficacy of Subsequent Lamivudine Therapy in Patients With Chronic Hepatitis BHEPATOLOGY, Issue 3 2000Yun-Fan Liaw M.D. Asian lamivudine trial has shown that hepatitis B e antigen (HBeAg) seroconversion rate during 1 year of lamivudine therapy was only 16% but was 64% in the subgroup of patients with a pretherapy serum alanine transaminase (ALT) level over 5 times the upper limit of normal (ULN). To test whether ALT rebound following corticosteroid priming enhances response to lamivudine therapy, a pilot study was conducted in 30 patients with ALT levels less than 5× ULN (43-169; N < 36 U/L). They received 30 mg of prednisolone daily for 3 weeks, 15 mg daily for 1 week, no treatment for 2 weeks, and then 150 mg of lamivudine daily for 9 months. Complete response (CR) was defined as ALT normalization with HBV-DNA seroclearance and HBeAg seroconversion. Peripheral blood mononuclear cell proliferation and cytokine secretion in response to recombinant HBV core antigen were serially assayed in 7 patients during priming and after withdrawal of prednisolone. Clinical rebound with an ALT over 5× ULN was observed in 20 patients (67%). Of these 20, 12 (60%) showed CR as compared with 1 (10%) of the 10 patients without significant ALT rebound (P < .002). The HBeAg seroconversion sustained in 70% of the patients 3 to 6 months after the end of lamivudine therapy. Immunological assays revealed that the responders showed Th1 dominant response and higher stimulation index to prednisolone priming. No serious side effect was encountered. These results suggest that corticosteroid priming induced immune/ALT rebound greatly enhances response to lamivudine therapy in chronic hepatitis B. Confirmation by randomized controlled trial is needed. [source] Steroid responsiveness in a case of Riedel's thyroiditis and retroperitoneal fibrosisINTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 3 2004P.K. Moulik Summary Riedel's thyroiditis is a rare chronic inflammatory disease of the thyroid characterised by an invasive fibrotic process. We present a lady with newly diagnosed hypothyroidism, rapidly enlarging hard, fixed goitre, strongly positive thyroid antibodies and raised erythrocyte sedimentation rate (ESR). A tru-cut biopsy confirmed Riedel's struma. Regression of the goitre and reduction of antibody titres occurred after starting prednisolone, which was stopped after 10 months. Six months later, she presented with renal failure due to retroperitoneal fibrosis that was successfully treated by reinstitution of steroids and ureteric stenting. Very high titres of thyroid antibodies and hypothyroidism predating development of goitre suggest coexistence of Hashimoto's thyroiditis and Riedel's thyroiditis. Tru-cut biopsy obviated the need for open thyroidectomy. A predominantly inflammatory as opposed to fibrotic thyroid histology may predict good response to steroids. Relapse following steroid withdrawal may not only be in the thyroid but also at other sites. [source] Resistant pityriasis lichenoides et varioliformis acuta in a 3-year-old boyINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2010Successful treatment with methotrexate Pityriasis lichenoides et varioliformis acuta (PLEVA) represents the acute clinical subtype of pityriasis lichenoides (PL) and its occurrence is relatively common during childhood. Diagnosis and treatment may sometimes pose certain difficulties. We present the recalcitrant case of a 3-year-old boy with an asymptomatic polymorphic eruption consisting of multiple, scattered, 0.5 cm, round to ovoid, erythematous papules covered in places with a fine scale, vesicles and superficial erosions with thick hemorrhagic crusts. The correlation of the clinical features with the lesional histopathology favored the diagnosis of PLEVA. No first-line treatment scheme succeeded in controlling the eruption of new lesions. The only therapeutic approach that eventually managed to cease the disease evolution was the combination of prednisolone and methotrexate. [source] Extranodal NK/T-cell lymphoma, nasal type, presenting after 5 years of remissionINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 3 2008Tomonobu Ito MD A 76-year-old woman with multiple edematous erythemas, erosions, and ulcers on the breast and abdomen was admitted to our hospital in June 2005. She had developed granulomatous bleeding lesions in the right nostril 6 years prior to her visit to our dermatology unit. She had been observed at the otorhinolaryngology department of our hospital, and a biopsy was taken from the nasal lesion. Computerized tomography and gallium scintigraphy (67Ga single-photon emission computed tomography) did not reveal any lesions corresponding to the diagnosis of malignant lymphoma. The histologic examination of the nasal specimen rendered a diagnosis of natural killer (NK)/T-cell lymphoma, nasal. Because imaging analysis indicated a small-sized tumor without metastases, oral prednisolone at 20 mg/day was administered for 1 month. The tumor decreased in size and disappeared after 19 months of low-dose steroid therapy. ,Five years after the initial treatment, the patient developed a fever of 38 °C with infiltrated erythemas and erosions on her breast. Erysipelas was initially suspected, but the antimicrobial agent did not show any effect and the multiple infiltrated erythemas and ulcers spread throughout her chest and abdomen (Fig. 1). The lymph nodes were not palpable. The right nasal cavity showed no granulomatous lesions or other signs of abnormality. The peripheral white blood cell count (3000/µL), red blood cell count (3.54 × 106/µL), and platelet count (112 × 103/µL) were reduced. Atypical lymphocytes were not observed. The serum lactic dehydrogenase (LDH; 1770 U/L; normal, 224,454 U/L), aspartate aminotransferase (AST; 140 U/L; normal, 10,30 U/L), and alanine aminotransferase (ALT; 57 U/L; normal, 3,29 U/L) levels were elevated. The soluble interleukin-2 (IL-2) receptor level was high (25,300 U/mL; normal, 167,497 U/mL). Epstein,Barr virus (EBV) serologic examination showed the immunoglobulin G (IgG) viral capsid antigen (VCA) at 1 : 320 and the EBV nuclear antigen (EBNA) at 1 : 40. IgM VCA and EBV early antigen-diffuse restricted antibody (EA) IgA and IgG were not detectable. Histologic findings from the left chest skin showed a distribution of atypical lymphocytes from the upper dermis to the subcutaneous tissue, and many foamy cells which had phagocytosed the hemocytes (Fig. 2a,b). Immunohistochemical analysis showed that the atypical lymphocytes were sCD3,, CD4,, CD8,, CD20,, CD56+, granzyme B+, and T-cell intracellular antigen (TIA-1) positive. Furthermore, EBV-encoded small RNAs (EBER), detected by in situ hybridization, exhibited a strong signal. The nasal lesions biopsied 6 years previously showed an identical staining pattern with the skin lesions immunohistochemically. Analysis of the T-cell receptor-, (TCR-,), TCR-,, and TCR-, gene did not reveal any clonal rearrangements, but the EBV gene was detected from the skin specimens by Southern blotting. Our patient's condition was diagnosed as a case of extranodal NK/T-cell lymphoma, nasal type, but the patient had concomitantly developed hemophagocytic syndrome (HPS). She was treated with a combination of steroid pulse therapy and chemotherapy (pirarubicin hydrochloride 30 mg/m2, cyclophosphamide 500 mg/m2, vincristine 1 mg/m2, prednisolone 30 mg/m2, etoposide 80 mg/m2). After the first session of chemotherapy, the lesions on the chest and abdomen diminished, but, 2 weeks later, the skin lesions recurred, and disseminated intravascular coagulation (DIC) induced by HPS supervened. The patient died as a result of multiple organ failure induced by HPS. Figure 1. Multiple infiltrated erythemas, erosions, and ulcers on the breast and abdomen Figure 2.

[source] Bullous variant of Sweet's syndromeINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 11 2005Susanne Voelter-Mahlknecht MD A 69-year-old woman presented to our clinic as an emergency with erythematous, well-circumscribed plaques, which were partly vesicular, on her extremities and in her armpits, and additionally hemorrhagic blisters on both her palms and her fingers (Fig. 1a), which had developed 2 days after the first appearance of the skin lesions. The rapid onset of the lesions (within a few hours) and the pain associated with them were extremely troublesome to the patient. On admission she complained of fever, tiredness and being easily fatigued. Because of a urinary tract infection 1 month prior to admission, trospiumchloride was given. On clinical examination, body temperature was found to be above 38 °C and infraclavicular lymph nodes were enlarged but not tender. Figure 1. (a) Bullae on the patient's right hand. (b) Multiple partly confluent vesicles with neutrophilic granulocytes intraepidermally and a dense interstitial perivascular infiltration of neutrophilic granulocytes and lymphomononuclear cells (H&E, ×200) Normal or negative laboratory tests included blood counts, liver and kidney parameters, electrolytes and infection screen. Laboratory examination demonstrated minor leukocytosis and absolute neutrophilia (white blood cell count 10 440 cells/µL, neutrophils 8030 cells/µL). X-ray screening, abdominal ultrasound and laboratory investigations were all normal. There was no response to antibiotics when erythromycine was given. However, there was a good response to systemic corticosteroids. The patient was treated with a low dosage of prednisolone, beginning at 50 mg/day, which was then tapered off. Skin lesions resolved within 7 days. Histology from a lesion on the patient's left forearm showed a dense interstitial inflammatory infiltration consisting predominantly of neutrophilic granulocytes from the subepidermal layer to the middle of the reticular dermis. Inflammatory cells penetrated into both blood vessels and vessel walls; vasculitis was not prominent. In the lower dermis, perivascular infiltrations of lymphomononuclear cells were found. In addition, intraepidermally multiple partly confluent vesicles, with inclusions of neutrophilic granulocytes, were found, confirming the diagnosis of this rare variant of an acute febrile neutrophilic dermatosis (Fig. 1b). [source] Cutaneous sarcoid-like granulomas with alveolar hemorrhage and c-ANCA PR-3INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 9 2004Natividade Rocha MD A 28-year-old woman, employed as a leather factory worker, noted asymptomatic, well-delimited plaques on both knees, 6 years ago. The plaques were violaceous with a smooth surface. One appeared over a post-traumatic scar from childhood (Fig. 1). Two years later, she began to complain of symptoms suggestive of polyarthritis, first of the small joints of the hands (proximal interphalanges) and then of the larger joints (wrists, elbows, and knees). She was diagnosed with rheumatoid arthritis and began treatment with nonsteroidal anti-inflammatory drugs for 1 month without any change. Deflazacort, 12 mg/day, and hydroxychloroquine, 400 mg/day, were administered for 3 months, with improvement of her articular complaints, but not her skin lesions. Figure 1. Well-delimited, violaceous plaques with a smooth surface on the knees, one over an old post-traumatic scar One year later, she complained of dysphonia, which remitted spontaneously after some weeks. After one additional year, she noted papules, with similar characteristics to the plaques, on the elbows, and two well-delimited orange-to-brown plaques on the forehead (Fig. 2). Figure 2. Orange,brown plaques symmetrically placed on the forehead During the fifth year of the disease, she was referred for the first time to a dermatologist, who biopsied one of the knee lesions. The histologic result was compatible with "sarcoid granuloma." At that time, she presented with skin lesions as her only complaint. Sarcoidosis was suspected based on a chest X-ray, which revealed hilar lymphadenopathy and diffuse accentuation of the interstitium. In November 2000, she suddenly developed fever (40 °C), cough with hemoptysis, dysphonia, and subcutaneous nodules on the palmar surface of the fingers of both hands that were painless, well-delimited, 5 mm in diameter, and firm (Fig. 3). She reported a weight loss of 12 kg in the previous 3 months. Pulmonary condensation was found on auscultation, and she had palpable hepatomegaly. Peripheral lymphadenopathy was not present. Figure 3. Painless, well-delimited, firm subcutaneous nodules on the palmar surface of the fingers Laboratory investigations revealed normochromic, normocytic anemia (hemoglobin, 7.7 g/dL), iron deficit, a white blood cell count of 16,000/µL with neutrophilia, an erythrocyte sedimentation rate of 130 mm/h, elevation of liver enzymes, a slight increase in angiotensin-converting enzyme (ACE) level (72 U/L), hypergammaglobulinemia (IgG, 3350 mg/dL), antinuclear antibody (ANA) of 1 : 320, and a slight increase in CD4 and decrease in CD8 lymphocytes with normal cellular morphology in blood. Renal function, urine sediment, urine and serum calcium, complement (C4), dsDNA, antimitochondrial antibody, direct and indirect Coombs test, antineutrophil cytoplasmic antibody (ANCA), tuberculin skin tests, viral markers of hepatitis B, C, and human immunodeficiency virus (HIV), electrocardiogram (ECG), ophthalmic examinations, and culture for infectious agents in blood and sputum were all normal or negative. Computed tomography (CT) scan showed an infiltrate in the upper right pulmonary lobule with a central cavity and bilateral hilar lymphadenopathy (Fig. 4). Homogeneous hepatosplenomegaly was present. The bronchoalveolar lavage (BAL) showed a slight lymphocytic increase predominantly of CD8 cells and hemosiderosis. Stains for infectious agents, including acid-fast bacillus, fungi, Mycoplasma, and Legionella, were negative. Three biopsies from the forehead, elbows, and knees showed well-formed noncaseating epithelioid cell granulomas with giant cells of the Langhans type in the dermis, suggestive of sarcoidosis (Figs 5 and 6). A fourth biopsy from a finger nodule demonstrated inflammatory infiltration of the dermis and necrosis with cellular debris. Vasculitis was not seen (Fig. 7). Figure 4. Computed tomography scan showing an infiltrate in the upper right pulmonary lobule with a central cavity Figure 5. Beneath a flattened epidermis, several sarcoid granulomas composed of epithelioid histiocytes and several multinucleated giant cells of Langhans type can be seen (hematoxylin and eosin, ×10) Figure 6. Less well-formed sarcoid granulomas in a hyperkeratotic area, surrounded by a sparse rim of lymphocytes (hematoxylin and eosin, ×20) Figure 7. Foci of necrosis and fibrinoid degeneration with some neutrophil infiltration and nuclear dusting (hematoxylin and eosin, ×40) The patient was treated with a broad-spectrum empirical antimicrobial (levofloxacin, 500 mg daily intravenously) over 12 days, with prompt improvement in her symptoms and remission of the forehead and finger lesions. Nevertheless, on the first evaluation after hospitalization, the CT scan showed persistence of the pulmonary cavity (Fig. 8). A repeat ANCA determination was positive (cytoplasmic pattern, c-ANCA) at 1 : 640 by indirect immunofluorescence (IIF). Antiproteinase-3 antibody was demonstrated at 78 by enzyme-linked immunosorbent assay (ELISA). Figure 8. Computed tomography scan showing persistence of the pulmonary cavity She underwent an open lung biopsy which revealed intra-alveolar hemorrhage and scanty noncaseating epithelioid cell granulomas of the sarcoidosis type in the peripheral blood vessels without vasculitis. A diagnosis of Wegener's granulomatosis was made and she began prednisolone (1 mg/kg/day) and oral cyclophosphamide (2 mg/kg/day). One year later, she is asymptomatic, the skin lesions have completely remitted, c-ANCA is negative, and the CT scan shows partial regression of the pulmonary cavity. [source] Extensive xanthelasma associated with anaplastic large cell lymphoma and hyperimmunoglobulin E syndromeINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2003Mi-Woo Lee MD A 57-year-old woman presented with a 6-month history of an extensively spreading, yellowish patch on the periorbital areas and cheeks. A diagnosis of hyperimmunoglobulin E syndrome had been made at the age of 22 years on the basis of an eczematous eruption, recurrent furunculosis, and a persistently elevated immunoglobulin E (IgE) level. Her past medical history revealed that she had suffered from numerous recurrent bouts of chronic sinusitis, otitis media, oral candidiasis, orbital cellulitis, acne rosacea, and pneumonia caused by cytomegalovirus since her twenties. In addition, 1 year ago, anaplastic large cell lymphoma of the cervical lymph node (stage IIIb) developed, and she received six cycles of cyclophosphamide,doxorubicin,vincristine,prednisolone (CHOP) chemotherapy with partial remission. None of her family had any of these problems. Cutaneous examination showed extensive, symmetric, noninfiltrated macular areas of distinct yellow discoloration around the eyes and on both cheeks (Fig. 1). There were also erythematous papulonodular eruptions on the nose and both cheeks, which were thought to be acne rosacea. Laboratory findings were normal, except for an elevated IgE level (8157 IU/mL). Serum concentrations of IgG, IgA, and IgM were normal. Serum complement levels were normal, as evidenced by normal C3, C4, and CH50. Although she had a previous history of a decreased level (12%) of nitroblue tetrazolium (NBT) test (control, 53%), NBT test at our institute was normal. Neutrophil function tests, including neutrophil chemotaxis, neutrophil phagocytosis, neutrophil respiratory burst, and neutrophil microbial killing test, by flow cytometry, showed normal results. The serum lipid levels, including total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and high-density lipoprotein-cholesterol, were normal. Serum lipoprotein electrophoresis was normal. A biopsy specimen revealed scattered foamy cells throughout the dermis. The larger clusters of foamy cells tended to group around the blood vessels of the dermis (Fig. 2). Figure 1. Extensively distributed, yellowish, flat xanthelasma on the face Figure 2. Clusters of foamy cells around the blood vessels of the dermis (hematoxylin and eosin, ×400) [source] Unusual case of cutaneous tuberculosis associated with rheumatoid arthritis: a case report and literature reviewINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2002G. Faghihi MD We report a 47-year-old female patient with a 10-year history of rheumatoid arthritis who presented with painful ulcerative plaques on the extremities at our clinic in St. Zahra University Hospital on February 2001. These plaques, diagnosed as cutaneous leishmaniasis, were 2 years old, but the patient was without any cure from the specific treatment she had been prescribed. Later, these skin lesions were misdiagnosed as pyoderma gangrenosum and she was treated by high-dose oral prednisolone, but she did not improve at all. After she was referred to our clinic, routine laboratory tests, PPD, chest X-ray and skin biopsy with tissue cultures were carried out. Finally, her cutaneous lesions turned out to be cutaneous tuberculosis, which responded successfully to antituberculosis treatment. [source] Leprosy in type I reaction and diabetes mellitus in a patient with HIV infectionINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002Alamengada D. Belliappa MBBS A 24-year-old man was referred to our department with history of a pale red raised lesion over the right side of the face with impaired sensation of 3 months' duration. He also had generalized weakness and increased thirst for the past 1 month. He had been treated with multidrug therapy for leprosy for 3 months and oral prednisolone for 1 month by his general practitioner. He also presented with a history of multiple sexual exposures with commercial sex workers and an ulcer over the penis 2 years ago, which healed spontaneously. [source] An unusual association of pemphigus vulgaris with hyperprolactinemiaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2002MNAMS, Sujay Khandpur MD A 21-year-old unmarried woman presented with oral ulcerations and generalized, itchy, fluid-filled, skin lesions of 10 days' duration. The lesions ruptured spontaneously, resulting in extensive denuded areas covered by crusts. One month prior to this, she experienced pain and enlargement of both breasts with galactorrhea. Her menstrual cycles were normal initially, but later she developed menstrual irregularities. No past history suggestive of any other systemic or skin disease, including atopy or drug allergies, could be obtained. Her family history was not contributory. Dermatologic examination revealed multiple, flaccid bullae and extensive denuded areas of skin covered with crusts over the scalp, face, trunk, and upper and lower limbs (Fig. 1). Bulla spread sign and Nikolsky's sign were positive. The oral mucosa, including the lips, buccal surface, tongue, and palate, showed multiple erosions covered with necrotic slough. The rest of the mucocutaneous and systemic examination was within normal limits. Figure 1. Extensive erosions and flaccid bullae over the trunk with breast enlargement The patient's diagnostic work-up revealed: hemoglobin, 11.2 g%; total leukocyte count, 7400/mm3; differential leukocyte count, P62L34E2M2; erythrocyte sedimentation rate, 34 mm/h. A peripheral blood smear examination, urinalysis, blood sugar, and renal and liver function tests were normal. Venereal Disease Research Laboratory (VDRL) test and enzyme-linked immunoabsorbent assay (ELISA) for human immunodeficiency virus (HIV) were nonreactive. Antinuclear antibody, lupus erythematosus (LE) cell, rheumatoid factor, and anti-dsDNA levels were normal. Serum protein electrophoresis demonstrated increased levels of immunoglobulin G (IgG) antibody. The serum prolactin level was significantly raised to 139.49 ng/mL (normal, 3.6,18.9 ng/mL). The sex hormone levels, however, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone, were within normal limits. The thyroid hormone profile was also unaltered. Chest X-ray was normal. Ultrasound of the abdomen and pelvis revealed no visceral abnormality and computerized tomography (CT) scan of the pituitary sella showed no adenoma. Mammography was negative for breast malignancy. A Tzanck smear prepared from the base of the erosion showed multiple acantholytic cells and lymphocytes. Histologic examination from an intact vesicle was suggestive of pemphigus vulgaris (PV), showing a suprabasal cleft with acantholytic cells and the basal layer demonstrating a "row of tombstones" appearance (Fig. 2). Direct immunofluorescence (DIF) revealed the intercellular deposition of IgG and C3 throughout the epidermis in a "fishnet pattern." Indirect immunofluorescence (IIF) test performed on rat esophagus for circulating IgG antibody was positive in a titer of 1 : 120. Figure 2. Photomicrograph showing suprabasal cleft with "row of tombstones" appearance, suggestive of pemphigus vulgaris (hematoxylin and eosin, × 40) Based on the clinical and immunohistological features, a diagnosis of PV with idiopathic hyperprolactinemia was made. The patient was treated with bromocriptine mesylate (Tablet Proctinal, Glaxo Wellcome Ltd, India) at a dose of 2.5 mg twice a day. After 2 months of therapy, significant improvement in the skin lesions was observed. The existing lesions re-epithelialized with a drastic reduction in the number and distribution of new vesicles. However, no change in the mucosal erosions was noticed. IIF test demonstrated a lower antibody titer (1 : 40). The breast complaints also improved with a reduction in serum prolactin level to 6.5 ng/mL. The patient refused further treatment as she experienced nausea and dizziness with bromocriptine. After 2 weeks, the disease relapsed with the appearance of new vesicles over the forearms, abdomen, back, and thighs. She again complained of breast tenderness and galactorrhea, and the serum prolactin level was 95 ng/mL. The IgG titer increased to 1 : 120. Hence, treatment with oral prednisolone (2 mg/kg/day) and bromocriptine (2.5 mg twice a day) with an antiemetic was initiated. After 6 weeks, the skin lesions had cleared completely, the breast symptoms had improved, menses had become regular, and the prolactin level had decreased to 4 ng/mL. IIF test was negative for circulating antibody. Steroids were tapered off and maintenance therapy with bromocriptine at a dose of 2.5 mg/day was continued. [source] Acute febrile neutrophilic dermatosis (Sweet's syndrome) with nodular episcleritis and polyneuropathyINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2002Taizo Kato MD A 56-year-old Japanese housewife presented with multiple erythematous lesions in association with ocular hyperemia and pain in the right upper and lower extremities, including the hands and feet. These symptoms were preceded by a sore throat with persistent fever higher than 38.5 °C for about 1 week. Dermatologic examination showed tender, dull-red, erythematous lesions, measuring 1,2 cm in diameter, located predominantly on the forehead, cheeks, auricular region, neck, forearm, hands, and feet. A biopsy specimen obtained from an erythematous lesion on the right forearm revealed prominent edema in the papillary dermis and remarkable inflammatory cell infiltration throughout the entire dermis (Fig. 1). The infiltrate predominantly consisted of neutrophils and nuclear dust without signs of vasculitis. In routine examination, the leukocyte count was 15,000/mL (normal range, 4000,8000/mL) with severe neutrophilia (80%). The C-reactive protein (CRP) level was 17.65 mg/dL (normal range, < 0.5 mg/dL) and the anti-streptolysin (ASLO) level was 611 IU/mL (normal range, < 166 IU/mL). In human leukocyte antigen (HLA) testing, HLA-A2, -B39, -B35, -Cw2, and -Cw7 were positive, and HLA-B51, -B54, and -Cw1 were negative. Figure Figure 1 . Histologic picture showing a dermal infiltrate of neutrophils Ocular hyperemia was caused by episcleritis forming a nodule and surrounding congestion of the superficial episcleritic vessels at the central portion of the sclera (Fig. 2). The patient suffered from pain once an hour, continuing for about 3 min, at the lateral portion of the right upper and lower extremities, as well as the right small finger. Neurologic examination demonstrated moderate or slight muscle weakness in the extremities. Hand grasping powers were 9 and 7 kg on the right and left, respectively. The patient was right-handed. Dysesthesia and paresthesia were also observed on the hands and feet. The deep tendon reflexes were preserved, however, even in the distal portion of the upper and lower limbs. In addition, essential tremor localized to the neck was recognized. Magnetic resonance imaging did not show any episodes of transient abnormal signal intensity in the central nervous system. Figure 2. Nodular episcleritis (right eye). Telangiectasia of winding vessels with nodular elevation was observed at the upper portion of the sclera The patient was treated with prednisolone (initial dose of 30 mg/day) and intravenous injection of cefazolin sodium (2 g/day for 5 days). Almost complete regression of the ocular and neurologic manifestations, as well as the skin lesions, was achieved in 2 weeks. Prednisolone was reduced gradually and suspended after 4 weeks. Leukocyte and neutrophil counts, CRP, and ASO returned to normal on suspension of therapy. Slight paresthesia remained in the right small finger even after stopping steroid. There was no recurrence at follow-up 6 months later. [source] Lichen planopilaris [cicatricial (scarring) alopecia] in a childINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 7 2001FNASC, FRAS (Lond.), Virendra N. Sehgal MD A mother of a 12-year-old boy, 2 years ago, noticed that he showed patchy loss of hair on the vertex of the scalp. It was asymptomatic and progressive. Subsequently, similar patches appeared elsewhere on the scalp. Some of these patches joined to form a large bald patch. This was accompanied by dusky blue eruptions over the left upper lip and eyebrows. Later, there was localized loss of hair. A family history of a similar ailment was absent. Examination of the scalp revealed plaques of alopecia with mild to moderate erythema. The skin was smooth, shiny, and atrophic (Fig. 1). Atrophy was apparent by the presence of wrinkles in places, and by holding the skin between the thumb and the index finger. The periphery of the lesions was well demarcated and was occupied by erythematous, scaly, follicular papules. Lesions were also located on the patches of alopecia. In addition, flat-topped, dusky blue, papules/plaques were present over the upper lip. Figure 1. Lichen planopilaris: plaques of alopecia showing smooth, shiny, atrophic skin with erythema A study of hematoxylin and eosin-stained microsections prepared from the upper lip and vertex of the scalp was undertaken. The former revealed hyperkeratosis, hypergranulosis, sawtooth irregular acanthosis, and destruction of the basal cell layer which, in turn, was embraced by a lymphohistiocytic infiltrate disposed in a band-like fashion. A few cells were seen invading the epidermis. Pigment-laden histiocytes were found intermingled with the infiltrate. In the scalp skin, on the other hand, atrophy of the epidermis with punctuation of keratin plugs, together with fibrosis of the dermis, was prominent. The walls of the hair follicles were hyperkeratotic, while their lumina were conspicuous by their dilatation and contained keratotic plugs (Fig. 2a,b). Sebaceous and sweat glands were absent. Figure 2. Lichen planopilaris showing atrophy of the epidermis, fibrosis of the dermis, dilatation of the hair follicle lumina containing keratotic plug(s), and hyperkeratosis of the wall of the follicle (hematoxylin and eosin: a , ×,40; b , ×,100) Response to treatment, comprising ultramicronized griseofulvin (Gris O.D.) 375 mg/day (Sehgal VN, Abraham GJS, Malik GB. Griseofulvin therapy in lichen planus ,- a double blind controlled trial. Br J Dermatol 1972; 86: 383,385; Sehgal VN, Bikhchandani R, Koranne RV et al. Histopathological evaluation of griseofulvin therapy in lichen planus. A double blind controlled study. Dermatologica 1980; 161: 22,27) and prednisolone 20 mg/day for 6 months, was excellent (Fig. 3). Topical betamethasone dipropionate (Diprovate) lotion was used as a supplement. Figure 3.

She looked healthy, but suffered from tenderness and swelling of the legs. Physical examination showed multiple, nonulcerating, erythematous nodules occurring on the calves, knee joints, and thighs (Fig. 1). A biopsy specimen of the skin revealed necrotizing vasculitis of medium-sized arteries with fibrinoid necrosis at the border between the dermis and the subcutis. Dense cellular infiltrates, including numerous neutrophils and lymphocytes, presented within and around the vessel walls as in polyarteritis nodosa, with some eosinophils (Fig. 2A,B). There were no other generalized symptoms. She was diagnosed with cutaneous polyarteritis nodosa and was initially treated with systemic steroids. She was given an intravenous injection of Solu-Cortef, 60 mg/6 h for 7 days. This was replaced with oral prednisolone for 2 weeks. The skin lesions and symptoms improved. Figure 1. Small, nut-sized, erythematous, brown-colored nodules and patches on the lower extremities, even above the knee joints Figure 2. (A) Dense infiltration within and around artery (× 40). (B) Slightly expanded lobular panniculitis with vasculitis (× 100) Six months later, she complained of general weakness and recurrent skin lesions. Purified protein derivative (PPD) test gave a moderate positive reaction and chest X-ray examination showed the features of pulmonary tuberculosis: radio-opaque infiltrations in the right lower lung field. A repeated biopsy revealed mild vasculitis with more diffuse lobular infiltrations of the subcutaneous tissue compared with the former specimen. Polymerase chain reaction (PCR) and tissue culture for Mycobacterium tuberculosis were performed from a biopsy specimen. DNA was extracted from skin tissue with an AplisystemTM DNA/RNA detection kit using the resin-mediated boiling method (Stargene, Seoul, South Korea). The primers were designed on the basis of the M. tuberculosis gene IS6110 target (sense primer, 5,-CCA GAT GCA CCG TCG AAC GGC TGA T-3, antisense primer, 5,-CGC TCG CTG AAC CGG ATC GAT GTG T-3,). The amplification was performed with uracil- N -glycosylase (UNG), to prevent carry-over contamination, and internal control primers, to correct for false-negative reaction (Kox LF, Rhienthong D, Miranda AM et al. A more reliable PCR for detection of Mycobacterium tuberculosis in clinical samples. J Clin Microbiol 1994; 32: 672,678; Longo MC, Berninger MS, Hartley JL. Use of uracil DNA glycosylase to control carry-over contamination in polymerase chain reactions. Gene 1990; 93: 125,128). According to the manufacturer's instructions, amplification was carried out for 40 cycles with denaturation at 94 °C for 40 s, annealing at 70 °C for 1 min, and extension at 72 °C for 1 min in a thermal cycler (Perkin,Elmer Cetus, Norwalk, CT, USA). The results of PCR and tissue culture for M. tuberculosis using the biopsy specimen were all negative (Fig. 3). Figure 3. Negative result in PCR for M. tuberculosis (negative control is not shown; M, marker; P, positive control; I, internal control; S, specimen) The patient was finally diagnosed with erythema induratum with pulmonary tuberculosis and was started on antituberculosis medication (isoniazid 400 mg, rifampicin 600 mg, ethambutol 800 mg, and pyrazinamide 1500 mg daily). She showed prompt improvement after 2 weeks of medication. After 9 months of antituberculosis therapy, her skin lesions and chest X-ray had cleared. She was followed up for 4 months with no recurrence of skin and pulmonary lesions. [source] Dermatomyositis presenting as panniculitisINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2000Yen-Yu Chao MD A 44-year-old obese woman was transferred to our clinic with a diagnosis of panniculitis. Examination showed multiple, indurated, erythematous, painful nodules and plaques distributed on the shoulders, back, forechest, abdomen, buttock, and bilateral thighs. These skin lesions appeared 2 months previously, measured 5,8 cm, and were tender on palpation. No obvious inducing factor was traced. The lesions seemed unresponsive to treatment with nonsteroidal anti-inflammatory drugs (ibuprofen, 400 mg three times a day) as similar lesions appeared in subsequent visits. Progressive proximal muscle weakness was found 1 month later. She was then admitted via the emergency room because of extensive painful skin plaques and abdominal pain. Diffuse erythematous to violaceous swelling of the face, neck, and shoulder was noted at about the same time ( Fig. 1). A skin biopsy specimen from the nodular lesion showed poikilomatous epidermal changes ( Fig. 2), and marked mononuclear cell infiltration in the dermis and subcutaneous fat ( Fig. 3). Dermatomyositis was considered as the diffuse violaceous facial erythema could be a form of heliotrope eruption, but Gottron's papule was not found. At admission, serum creatinine phosphokinase (CPK) was mildly elevated (436 IU/L; normal range, 20,170 IU/L), but serum asparagine transaminase (AST) and lactate dehydrogenase (LDH) levels were within normal limits (36 IU/L; normal, 11,47 IU/L; and 108 IU/L; normal, 90,280 IU/L, respectively). Antinuclear antibody was 1 : 80 positive with an atypical speckled pattern. Muscle strength was weakest during the first 2 days, about grade 3 by the Medical Research Council (MRC) of Great Britain scale. Gower's sign was positive. An electromyogram showed myopathic changes and a nerve conduction velocity study was normal. Serum enzymes were elevated further on the third day: AST, 55 IU/L; CPK, 783 IU/L with 100% MM form. The diagnosis of dermatomyositis was established. As for the work-up result, anti-dsDNA antibody, anti-ENA antibody, and anti-Jo1 antibody were negative. Tumor marker screen (,-HCG, AFP, CEA, and CA-125), was negative, and rhinolaryngopharyngoscope examination and gynecologic sonography were normal. Figure 1. Diffuse erythematous swelling with subtle violaceous hue extending from the temporal area to the cheeks, neck, and shoulders. The crusted lip ulcers of herpes simplex were also noted Figure 2. Basketweave hyperkeratosis, mild acanthosis, subtle vacuolar degeneration of the basal cells, and melanin incontinence (hematoxylin and eosin, ×400) Figure 3. Heavy mononuclear cells infiltrated in the subcutaneous fat tissue (hematoxylin and eosin, ×100) Pancreatitis was initially suspected because of epigastric pain and tenderness, elevated serum lipase (382 U/L; normal, 23,200 U/L), and amylase (145 U/L; normal, 35,118 U/L). No evidence of pancreatitis could be found in abdominal sonography and abdominal computed tomography (CT), however. The epigastric pain and tenderness subsided soon after admission and the serum pancreatic enzyme level declined on the second day (amylase 69 U/L; lipase, 276 U/L). The patient was then diagnosed with dermatomyositis and treated with prednisolone (120 mg/day). CPK dropped dramatically from 3286 IU/L the day before treatment to 1197 IU/L 3 days after. Panniculitis lessened and the muscle power improved after 1 week of treatment. The disease activity fluctuated even with treatment with prednisolone and the patient often felt listless and weak. The muscle weakness sometimes deteriorated to affect the patient's mobility. Facial erythema and panniculitis-like lesions were found during the worse times. Methotrexate and azathioprine were then added (7.5 mg and 250 mg per week, respectively), but CPK was still mildly elevated (189 IU/L), and the patient still felt ill. Human immune globulin (5%, 500 mL per day, 5 days per month) intravenous infusion was initiated thereafter. There was a dramatic response. Full muscle strength was retained and CPK was within the normal range in the following 6 months with only immune globulin therapy. [source] | ||||||||||||||||||||||||||||||||||||||||
