Topical treatment of intraepithelial penile carcinoma with imiquimod

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 2003
G. Micali
Summary Intraepithelial penile carcinoma (IPC) is an in situ carcinoma of the penis, which can be difficult to diagnose. Current treatments include excisional surgery, Mohs' micrographic surgery, cryotherapy, carbon dioxide laser therapy and topical 5-fluorouracil. We report two cases of men with 12,18 month histories of IPC (Bowen's disease, squamous cell carcinoma in situ) that were previously unsuccessfully treated with antifungals and antibiotics. Treatment with imiquimod 5% cream for 8,10 weeks was effective in both cases with no clinical evidence of relapse at 4 and 6 months. Both patients experienced adverse effects, resulting in temporary discontinuation of treatment. [source]


Fine-needle aspiration of subcutaneous panniculitis-like T-cell lymphoma

DIAGNOSTIC CYTOPATHOLOGY, Issue 5 2004
Frances Manosca M.D.
Abstract We report the fine-needle aspiration (FNA) cytology findings of Subcutaneous Panniculitis-like T-cell Lymphoma (SCPTCL) in a 66-year-old woman who presented with a four month history of asymptomatic subcutaneous nodules on her right chest wall and back. An excisional biopsy of the right chest nodules was performed, and the diagnosis of SCPTCL was rendered. On a follow-up visit, several skin lesions were noted throughout her body. A fine-needle aspiration (FNA) of the right inguinal region was performed. The FNA yielded cellular smears, composed mainly of sheets of epithelioid histiocytes and scattered multinucleated cells. However, no distinct granulomas were noted. The background of the cytological smears showed scattered atypical lymphoid cells, some of which displayed nuclear membrane irregularities. To the best of our knowledge, the cytological features on FNA material of SCPTCL have not been described. Diagn. Cytopathol. 2004;31:338,339. © 2004 Wiley-Liss, Inc. [source]


Chronic telogen effluvium or early androgenetic alopecia?

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 11 2004
Rodney Sinclair MBBS
A 16-year-old girl presented with a 12-month history of generalized hair shedding from the scalp. The onset of shedding coincided with the development of Hashimoto's thyroiditis and iron deficiency. At the time of initial presentation, the Hashimoto's thyroiditis had been treated with Neo-Mercazole and she was euthyroid. Her iron stores were low, with a ferritin level of 13 µg/L. As she was vegetarian, oral iron replacement therapy was commenced without further investigation. On follow-up 6 months later, her iron stores were normal (ferritin, 36 µg/L), but the hair shedding had continued. On examination, there was a positive hair pull test from both the vertex of the scalp and the occipital scalp. There was mild bitemporal recession, but no widening of the central part, and she appeared to have a full, thick head of hair (Fig. 1). Additional investigations at that time revealed normal thyroid function and negative antinuclear antibody (ANA) and syphilis serology. She was on no medication other than Neo-Mercazole. Serum testosterone, dihydroepiandosterone sulphate (DHEAS) and sex hormone binding globulin (SHBG) were normal. Two 4-mm punch biopsies were taken from the vertex of the scalp; one was sectioned horizontally and the other vertically. The vertical section was unremarkable. On the horizontal section, there were 32 hair follicles in total, 30 of which were terminal hairs and two of which were vellus hairs. One hair was in telogen. The ratio of terminal to vellus hairs was 15 : 1. Figure 1. Initial presentation A diagnosis of chronic telogen effluvium was made. The condition was explained to the patient and she was reassured that chronic telogen effluvium is not a progressive condition and does not lead to baldness. No treatment was recommended. At follow-up 12 months later, the hair loss had obviously progressed and the patient was assessed as having Ludwig Stage 1 androgenetic alopecia with widening of the central part (Fig. 2). Repeat blood tests showed normal iron studies, thyroid function, and hormone parameters. Three 4-mm punch biopsies were taken from the vertex of the scalp and all were sectioned horizontally. The terminal to vellus hair ratios were 1 : 1, 2.6 : 1, and 1.9 : 1. A diagnosis of androgenetic alopecia was made and she was commenced on oral spironolactone, 200 mg/day. Figure 2.

Large B-cell lymphoma of the leg

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 10 2001
Elsa Vasquez-del-Mercado MD
A 74-year-old Mexican man presented with an 18-month history of multiple, violaceous, coalescing, firm, tender nodules with an ulcer in the anterior aspect of the right leg (Fig. 1) and slightly infiltrated, ill-defined erythematous plaques affecting the left leg and both forearms. He had not received any treatment for his condition. Past medical history was relevant for noninsulin-dependent diabetes mellitus and hypertension without formal treatment and a history of heavy alcohol intake in his youth. A biopsy specimen of both plaque-type lesions of the forearm and tumorous lesions of the leg showed a diffuse, nonepidermotropic mononuclear infiltrate throughout the dermis and extending to the subcutis. The infiltrate was composed of pleomorphic, atypical, large mononuclear cells (Fig. 2). Immunostaining with CD20 was positive for the atypical cells while CD3 was positive for normal appearing lymphocytes, characterized as reactive T cells. Additional laboratory and image studies ruled out extracutaneous involvement. The diagnosis of primary cutaneous large B cell lymphoma of the leg (LBCLL) was made. The patient was initiated on radiotherapy localized to the right leg with a very good initial response, nevertheless resolution was not achieved and the plaques in the rest of the limbs remained unchanged. Thus, the patient started chemotherapy with CHOP (Cyclophosphamide, Vincristine, Doxorubicin, Prednisone). He has currently finished his fourth cycle with this chemotherapy regimen. The tumorous lesions involuted leaving only residual hyperpigmentation (Fig. 3) and the plaques in the rest of the limbs disappeared, the area of the ulcer diminished considerably. There is still no evidence of extracutaneous involvement. Figure 1. Nodules and ulcer in the anterior aspect of the right leg Figure 2.

Erythema dyschromicum perstans and hepatitis C virus infection

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 5 2001
George J. Kontochristopoulos MD
A 48-year-old woman with a 10-month history of widespread, hyperpigmented, slightly pruritic macules, with a red border, involving the trunk and the proximal limbs (Fig. 1) was referred to our outpatient department. The oral mucosa, palms, soles, scalp, and nails were normal. Figure 1. Multiple hyperpigmented macules with an active border on the trunk Laboratory tests showed elevated liver enzymes [alanine aminotransferase (ALT), 68 IU/L (normal value, <,40 IU/L); aspartate aminotransferase (AST), 41 IU/L (normal value, <,40 IU/L)], the presence of antibodies to hepatitis C virus (anti-HCV) and HCV RNA (Amplicor Roche). In addition, cryoglobulinemia type III (IgM,,,, IgG,,,) was detected with a high cryocrit value, and there was detectable C-reactive protein, rheumatoid factor, and a low titer of antinuclear antibodies (1 : 80). A percutaneous liver biopsy showed changes compatible with mild chronic hepatitis (grade, 6; stage, 0). The possible source of infection was unknown, as the patient had no history of parenteral transmission (e.g. blood transfusions, intravenous illicit drug use). A skin biopsy specimen from the active border of a lesion showed hyperkeratosis, parakeratosis, and hydropic degeneration of the basal cell layer, with the formation of colloid bodies in the epidermis. A moderate perivascular lymphohistiocytic infiltrate with melanophages and free melanin granules was observed in the upper dermis (Fig. 2). Immunostaining of paraffin-embedded tissue sections with the TORDJT-22 IgG1 mouse monoclonal antibody to HCV (Biogenex, Son Ramon, USA), which is specific for the nonstructural region of HCV (NS3-NSH, C100 antigen) using the avidin,biotin,peroxidase complex (ABC) as well as the alkaline phosphatase antialkaline phosphatase (APAAP) methods, failed to detect HCV in the lesion of erythema dyschromicum perstans (EDP) (Nakopoulou L, Manolaki N, Lazaris A et al. Tissue immunodetection of C100 hepatitis C virus antigen in major thalassemic patients. Hepato-Gastroenterol 1999; 46: 2515,2520). Direct immunofluorescence showed IgG, IgM, IgA, and fibrinogen deposits on colloid bodies. EDP was diagnosed on the basis of these clinical and laboratory findings. Figure 2. Hydropic degeneration of the basal cell layer with colloid bodies in the epidermis. Moderate perivascular lymphohistiocytic infiltrate with melanophages and free melanin granules in the upper dermis (hematoxylin and eosin, ×,200) The patient was treated with interferon-,2b (Intron-A, Schering Plough Athens, Greece), 3 MU thrice weekly subcutaneously for 12 months, with additional topical steroid application. There was no response to this treatment with new lesions appearing in previously unaffected areas of the trunk and extremities. HCV RNA remained persistently positive. Thus, a modified regimen with interferon-,2b, 6 MU thrice weekly for 6 months, was tried. At the end of the treatment course, the eruption of EDP had greatly improved. Liver enzymes were normal (ALT, 22 IU/L; AST, 24 IU/L) and HCV RNA had become negative. Four months later, however, cutaneous lesions reappeared and hepatitis C relapsed. At this time point, combination therapy of interferon-,2b, 3 MU thrice weekly, with ribavirin, 1000 mg daily, was given. Six months later, liver enzymes were normal (ALT, 42 IU/L; AST, 39 IU/L), HCV RNA was negative, and the lesions of EDP had resolved. [source]

Eva J. Soelaeman
Helicobacter pylori eradication has been debated. Most investigators do not recommended treating the infection except in severe case. We report a unique case: H. pylori infection with appendicitis and lactose intolerance. Case report: A 6 year old girl was brought to children and maternity Hospital Harapan Kita due to abdominal pain and vomiting. She had 6- month history of epigastric pain. In the past 2 days, she suffered from abdominal pain arround Mc. Burney area. On physical examination, she was in pain. Her weight was 19 Kg. Vital signs were normal. Findings in heart, lung and extremities were also normal. Abdomen: severe pain in the epigastric and Mc. burney area.Laboratory investigations showed hemoglobin 12 g/dl, leukocyte 12800/ul. Platelets 289000/ul. Bleeding and clotting time were normal. Abdominal ultrasonography revealed inflammation of appendix with 9-mm diameter. Stool examination was normal.Appendectomy was done at the same time with esofagogastroduodenoscopy (EGD). On EGD, we found moderete anthral gastritis. On histopathological examination, we found H. pylori at antral of the stomach. Breath hydrogen test was positive. After H. pylori eradication and milk avoidance, abdominal pain has never occurred. Conclusion: Abdominal: pain is not specific for H. pylori infection. The pain caused by many diseases including H. pylori infection. In our case, we can control abdominal pain by H. pylori eradication. [source]


Magnetic resonance imaging and pathological findings in a case of canine idiopathic eosinophilic meningoencephalitis

JOURNAL OF SMALL ANIMAL PRACTICE, Issue 8 2007
C Salvadori
A case of idiopathic eosinophilic meningoencephalitis in a six-month-old male Maremma shepherd dog is reported. The dog was referred with a four month history of progressive weakness and depression with loss of trained habits. Tendency to recumbency, disorientation, visual impairment, bilaterally decreased menace response and hindlimb conscious proprioception deficits were detected. Magnetic resonance imaging showed a diffuse hypointense signal involving the cerebral grey matter with enlargement of the cerebral sulci on T1-weighted and fast fluid-attenuated inversion recovery (FLAIR) sequences consistent with a diffuse necrosis or atrophy of the cortical grey matter. Histological examination revealed severe inflammatory infiltration mainly composed of eosinophils and macrophages in the subarachnoid space and in the superficial layer of the cerebral cortex where parenchymal rarefaction and necrosis of neurones were also evident. No parasites, cysts or fungi were detected, and an immunologically mediated disorder was suspected. Magnetic resonance imaging may represent a useful diagnostic tool to differentiate idiopathic eosinophilic meningoencephalitis from other inflammatory brain diseases of young dogs. [source]


Validity of the Alcohol Use Disorders Identification Test in College Students

ALCOHOLISM, Issue 6 2004
Patricia K. Kokotailo
Background: High-risk alcohol use among college students is associated with accidents, partner violence, unwanted sexual encounters, tobacco use, and performance issues. The identification and treatment of high-risk drinking students is a priority for many college campuses and college health centers. The goal of this study was to test the psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) in college students. Methods: A convenience sample of students coming into a college health clinic was asked to complete the 10-question AUDIT and then participate in a research interview. The interview focused on assessing students for alcohol abuse and dependence by using the Composite International Diagnostic Interview Substance Abuse Module and timeline follow-back procedures to assess a 28-day drinking history. Results: A total of 302 students met the eligibility criteria and agreed to participate in the study. The sample consisted of 185 females (61%) and 117 males (39%), with a mean age of 20.3 years. Forty students were abstinent, 88 were high-risk drinkers, and 103 met criteria for a 12-month history of dependence. Receiver operator curves demonstrated that the AUDIT had the highest area under the cure for detecting high-risk alcohol use (0.872) and the lowest for identifying persons with a lifetime history of alcohol abuse or dependence (0.775). An AUDIT cutoff score of 6 or greater demonstrated a sensitivity of 91.0% and a specificity of 60.0% in the detection of high-risk drinkers. Conclusions: The AUDIT has reasonable psychometric properties in sample of college students using student health services. This study supports the use of the AUDIT in this population. [source]

Article first published online: 11 MAR 200
Siciliano G.1, D'Avino C.1, Panichi V.2, Azzarà A.3, Del Corona A.1, Pollina L.3, Murri L.1 1Department of Neuroscience, 2Department of Internal Medicine and 3Department of Oncology,University of Pisa-Italy Amyloidosis is a systemic disease with a wide organic involvement. Amyloidotic polyneuropathies may be genetic in their origin or present in association with a number of chronic inflammatory dysimmune disorders. We report on three patients affected by predominantly sensitive polyneuropathy, monoclonal gammopathy and amyloidosis. Patient 1. Woman, 72 years old, with a one year history of painful paraesthesias, ataxic gait and demyelinating predominantly sensitive polyneuropathy at 4 limbs also with involvement of sympathetic fibres. Blood protein electrophoresis showed a monoclonal gammopahty (IgG-k) with normal bone marrow biopsy and positivity for amyloid at fat biopsy. The patient has been treated with melphalan 0.2 mg/Kg/day+prednisone 100 mg/day for 7 days each month for 6 months with good efficacy and only a transient reduction in platelet and white blood cells count. Patient 2. Man, 60 years old, new diagnosis of diabetes with a 9 month history of painful paraesthesias and hyposthenia, a demyelinating sensory-motor polyneuropathy at 4 limbs. The patient presented an IgG-, monoclonal gammopathy with normal bone marrow biopsy, fat biopsy but not sural nerve biopsy positive for amyloid. The patient underwent melphalan+prednisone therapy, with insulinic control of glycemia. He presented a clear-cut improvement in sensitive-motor symptomatology. Patient 3. Man, 72 years old, with a 15 year history of ulcerous rectocolites. Since 1998 started complaining of paraesthesias and disaesthesias at four limbs associated with gait disturbances. The patient presented an IgG-, monoclonal gammopathy with normal bone marrow aspiration and elevated serum Interleukin-6 levels, fat biopsy positive for amyloid, and high anti-MAG antibodies titer (1:100000). Because of RCU, melphalan therapy was excluded and the patient is at the moment under fludarabine (25 mg/m2/day) ev for 5 days each 6 weeks for 6 bouts. [source]


CONTROLLED-RELEASE OXYCODONE RELIEVES MODERATE TO SEVERE PAIN IN A 3-MONTH STUDY OF PERSISTENT MODERATE TO SEVERE BACK PAIN

PAIN MEDICINE, Issue 2 2002
Article first published online: 4 JUL 200
Patricia Richards, MD, PhD; Pinggao Zhang, PhD; Michael Friedman, PhD; Rahul Dhanda, PhD. (Purdue Pharma L.P.) Introduction: Opioids are frequently prescribed for management of persistent low back pain, however, efficacy has not been well documented, and concerns are that opioids may impair physical functioning. Objective: To compare controlled-release oxycodone (CRO) with placebo in controlling pain and to observe the effect of CRO on quality of life and functionality. Methods: A double-blind, randomized, placebo-controlled, parallel-group study of 3 months duration was conducted in 110 subjects (49 males, 61 females), mean age 48 years (19,80 years). Subjects had a 3- to 12-month history of moderate to severe persistent low back pain and were previously unresponsive to therapeutic doses of NSAIDs, and/or low dose combination opioid analgesics. At baseline 4% of subjects were on opioids, 39% on NSAIDs, and 57% both NSAIDs and opioids. Subjects were treated with 10 mg CRO tablet or 10 mg oral placebo q12h, titrated to stable pain control. Existing treatment regimens of acetaminophen, NSAIDs, or oral steroids were allowed to continue. The Brief Pain Inventory (BPI), the Roland Morris Functionality Questionnaire, and the MOS 36-Item Short-Form Health Survey (SF-36) were the measures of pain intensity, functionality, and quality of life. Treatments were compared using repeated measures ANCOVA with baseline value as covariate. Results: CRO treatment was significantly superior to placebo on the BPI average pain intensity and average percent pain relief scores overall (4.6 vs 5.4, P = .03, and 47.2 vs 36.3, P = .05, respectively). Fewer CRO subjects discontinued because of inadequate pain control (P < .001). No significant differences between treatments were observed in either Roland Morris or SF-36 scores. Common adverse events for CRO were nausea, constipation, somnolence, headache, and pruritus, consistent with opioid use. Conclusions: Three-month treatment with CRO provides significant pain relief for subjects with persistent moderate to severe back pain, without significantly impairing functionality and quality of life.

Giant basal cell carcinoma masquerading as an osteogenic sarcoma

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2009
Paul Cherian
SUMMARY An 88-year-old man presented to the dermatology outpatient clinic with an 11-month history of a rapidly growing mass overlying a clavicular fracture site. The lesion was 8 × 6 cm, painful, fixed to deeper structures and ulcerated. Superficial and deep biopsies yielded invasive basal cell carcinoma. Imaging demonstrated extensive soft tissue invasion into muscle, bone and potentially into the lung parenchyma. Due to complications arising from subsequent diagnostic procedures, the patient declined further invasive tests. The cutaneous lesion was treated with palliative radiotherapy. We explore the literature regarding the tumorigenic effects of peri-fracture cytokines on the biological behaviour of basal cell neoplasms. [source]

Jeremy P Banky
SUMMARY A 74-year-old woman presented with an 18-month history of broken vertex scalp hairs as a consequence of chronic rubbing. Light microscopy of the 1,2 cm hairs demonstrated distal brush-like splitting. Education and behavioural therapy were instituted. After 4 months of reduced rubbing of the vertex scalp hairs, the hairs re-grew with no evidence of persistent hair shaft abnormality. [source]


Cheilitis caused by contact urticaria to mint flavoured toothpaste

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2001
Gary Holmes
SUMMARY A 26-year-old woman presented with a 12-month history of persistent dermatitis of the lips. She had failed to respond to cosmetic avoidance and therapeutic measures. Patch testing was negative, including her toothpaste and toothpaste flavours. She defied diagnosis until an acute flare followed immediately after dental treatment with a mint flavoured tooth cleaning powder. This led us to prick test her to mint leaves and this was positive. Her cheilitis settled after changing from her mint-flavoured toothpaste. A diagnosis of contact urticaria should be considered in cases of cheilitis of unknown cause. [source]


Rosacea lymphoedema of the eyelid

ACTA OPHTHALMOLOGICA, Issue 6 2004
Tze Foon Lai
Abstract. Purpose:,To present a patient with rosacea lymphoedema of one upper eyelid resulting in unilateral complete ptosis. Methods:,A 51-year-old white man presented with a 12-month history of progressive painless swelling of the left upper eyelid. An incisional biopsy of the upper eyelid was performed. Results:,The biopsy showed dermal oedema with lymphangiectasia and telangiectasia, accompanied by a mild to moderate mixed chronic inflammatory infiltrate of lymphocytes, histiocytes, plasma cells and rare eosinophils. Stains for fungi and mycobacteria were negative. The lack of lichenoid reaction, dermal mucin or lip swelling indicated a lymphoedematous manifestation of rosacea. The patient was treated with minocycline and prednisolone with no effect. Conclusion:,Rosacea lymphoedema involving the eyelid, as in our case, is a rare complication and can present diagnostic and therapeutic challenges to the ophthalmologist. [source]
