Left Forearm (leave + forearm)
Selected AbstractsBullous 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] Multiple pilomatricoma with perforationINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 12 2002Emel Fetil MD A 22-year-old woman presented to our clinic with a complaint of masses on various parts of her body. A mass on her right forearm had appeared 5 years ago and had enlarged during the past 6 months. Two lesions on the back of her neck had a 3-year history, one lesion on her eyebrow had a 2-year history, and one lesion on her left forearm had a 1-year history. The lesion on her left forearm was discharging purulent material. Dermatologic examination revealed a 15 × 16 mm tumor on the right forearm, 11 × 6 mm and 10 × 5 mm tumors on the back of the neck, and a 20 × 20 mm tumor on the eyebrow; they were flesh-colored, well-defined, firm tumors. On her left forearm, there was a 12 × 10 mm, well-defined, firm, blue,red tumor discharging chalky white granules; purulent material was detected (Fig. 1). Figure 1. Firm, blue,red tumor discharging chalky white granules There was no regional lymphadenopathy. Systemic examination was normal. Laboratory examination of hematologic, biochemical, and urinalysis tests was normal. There was no family history of similar lesions. Total excision of all the tumors was performed. Histopathologic examination of the material revealed clusters of eosinophilic shadow cells surrounded by a fibrous capsule. There were also foreign body giant cells. Areas of calcification, cholesterol clefts, and ossification were detected. An intraepidermal perforating area was detected from the biopsy material of the left forearm (Fig. 2). There were no recurrences after 1 year of follow-up. Figure 2.

The patient had been treated with multidrug therapy for 8 months for lepromatous leprosy. During therapy, he developed recurrent episodes of reactions which were treated with high doses of prednisone and thalidomide. The histopathology of the cutaneous nodular lesion showed a granulomatous inflammatory infiltrate; some histiocytes contained vacuolations and others demonstrated oval-like or coma-like structures (Fig. 2). The specimen was cultivated in Sabouraud agar at room temperature. The colonies were transferred to Petri dishes containing Niger Seed Agar (NSA) (Fig. 3). The confirmed diagnosis was Cryptococcus neoformans var. neoformans based on microscopy and physiology, including the canavanine,glycine,bromothymol blue (CGB) medium (Lazéra MS, Pires FDA, Camillo-Coura L et al. Natural habitat of Cryptococcus neoformans var. neoformans in decaying wood forming hollows in living trees. J Med Vet Mycol 1996; 34: 127,131). The liquor culture was negative. Hemoculture and urine culture were also negative. Latex agglutination test was blood positive and liquor negative. Figure 1.

Granulomatous infiltrate presenting oval-like or coma-like structures inside the histiocytes (mucicarmine stain, ×,100) Figure 3. Petri dishes with Niger Seed Agar containing numerous colonies of Cryptococcus neoformans var. neoformans The patient's hemogram revealed normocytic anemia and normal total and differential white blood count. The CD4 count was 189/m3 and the CD8 count was 141/m3. Serology for anti-human immunodeficiency virus-I (anti-HIV-I) antibodies was negative. The X-ray of the lungs showed an areolar image in the superior lobe of the right lung. Therapy with prednisone was suspended and fluconazole (300 mg/day) was prescribed. The nodular cutaneous lesion regressed completely after 90 days. The patient was submitted to a second skin biopsy for treatment control. The culture of the specimen taken was still positive and the histopathology showed the same picture as before treatment. After 5 months of continued therapy with fluconazole, another biopsy was performed but no fungus was recovered from the specimen. [source] Eruptive squamous cell carcinomas, keratoacanthoma type, arising in a multicolor tattooJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2008Gary Goldenberg Permanent tattoos are formed through the injection of ink solids through the epidermis into the dermis and can cause multiple adverse reactions. We report a 38-year-old man who presented to our Dermatologic Surgery Unit with a diagnosis of a superficially invasive squamous cell carcinoma (SCC), keratoacanthoma (KA) type, of the left forearm in a 1-month-old tattoo. Since his initial biopsy, he developed four more similar lesions on his left forearm within his tattoo. On physical examination, the patient had a large, multicolor tattoo on his left forearm, a well-healed surgical biopsy site and four erythematous hyperkeratotic papules within differently pigmented areas of the patient's tattoo. Histopathological examination showed KA and tattoo pigment. Based on the eruptive nature of these lesions, their clinical presentation and the histopathological changes, we report this as the first case of eruptive KA arising in a multicolor tattoo. [source] Pediatric primary cutaneous marginal zone lymphoma: in association with chronic antihistamine useJOURNAL OF CUTANEOUS PATHOLOGY, Issue 2006Novie Sroa There have been no prior reports of this lymphoma occurring in American children. We present a case of a 15-year-old male with a history of atopic diathesis and chronic use of antihistamine agents who presented with an asymptomatic lesion on his left forearm of 6 months duration. Because histopathological and immunohistochemical studies were compatible with marginal zone lymphoma, and the patient had no associated extracutaneous disease, the diagnosis of primary cutaneous marginal zone lymphoma was rendered. Based on the patient's past medical history prior to appearance of lesion, it was postulated that the development of lymphoma was associated with the ingestion of antihistamines and further propagated by his underlying atopic diathesis. [source] Characterization of autonomic dysfunction in patients with irritable bowel syndrome using fingertip blood flowNEUROGASTROENTEROLOGY & MOTILITY, Issue 5 2008T. Tanaka Abstract, Fingertip blood flow (FTBF) as measured by laser Doppler flowmetry (LDF) measurement is considered an indicator of sympathetic nerve function. We evaluated autonomic function in patients with irritable bowel syndrome (IBS) by assessing FTBF with both LDF and continuous-wave (cw) Doppler sonography. Firstly, the two methods were compared in 40 healthy volunteers. Next, 59 patients with IBS as well as 118 healthy volunteer controls were studied. In the supine position, FTBF in the right index finger was measured with cw Doppler sonography, whereas FTBF in the left index finger was assessed with LDF. After baseline measurement for at least 5 min, the volunteers received sympathetic stimulation from cold stress applied without notification in the form of an icebag (0 °C) upon the left forearm for 1 min. The new cw Doppler sonography method can be used in place of the old LDF method for clinical purposes. FTBF velocity before stimulation (Vpre) was significantly lower in the IBS group than that in the healthy volunteers (P < 0.01). In addition, the time required for FTBF to return to Vpre after stimulation was significantly longer in the IBS group than that in the control group. (P = 0.02). Thus, measurement of FTBF with cw Doppler sonography can be useful in the assessment of sympathetic nerve function. The IBS patients showed an abnormal FTBF response suggesting the presence of excess sympathetic activity. [source] Linear Morphea Presenting as Acquired Unilateral EdemaPEDIATRIC DERMATOLOGY, Issue 2 2007Katherine H. Fiala M.D. In addition, linear hypopigmented patches were noted along the left forearm and leg, with no appreciable scarring or induration. The edema on the left-hand side of his body progressed so that he developed tense bullae on his left hand. Two months later, the hypopigmented patches were indurated and bound-down, especially over the left groin and thigh. A biopsy specimen from this area showed features characteristic of morphea. In this patient, dilated lymphatic channels secondary to the sclerosis of the morphea caused the bullae. Bullous morphea is a rare condition. We were unable to find any reports its occurrence in children under 18 with associated lymphedema. This entity should be included in the differential for acquired unilateral edema in children. [source] Combined oral oestradiol valerate-norethisterone treatment over three years in postmenopausal women: correlation between oestrogen levels and bone mineral density sitesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 11 2000W. Perry Consultant Endocrinologist Objective To compare trabecular and compact bone response and relationship to oestrogen status using continuous oestradiol valerate 2 mg and norethisterone 0.7 mg daily as hormone replacement and to determine the therapeutic range of 17 beta-oestradiol. Design Open label trial. Setting Independent endocrine clinic Sample One hundred and thirty-one patients were compared at point of entry and at 36 months. Methods Postmenopausal women were assessed using a Lunar dual photon and single photon bone scanner, and bone mineral density of the lumbar spine, right hip and left forearm were annually correlated with 17 beta-oestradiol and oestrone levels over three years. Total alkaline phosphatase was compared between improvers and decliners of bone mineral density. Results Significant improvement in bone mineral density (P < 0.0001) occurred at all sites except the left forearm, where bone loss was prevented. There was no correlation between oestrogen levels and bone mineral density improvements at hip sites. However, in the lumbar spine larger improvements in bone mineral density occurred in women with 17 beta-oestradiol levels > 185 pmol/L compared with those below, which were statistically significant for those with 17 beta-oestradiol levels > 248 pmol/L. Bone turnover, as quanitifed by total alkaline phosphatase measurements, was suppressed in most patients, but there were no differences in the mean alkaline phosphatase levels between the best improvers and worst decliners for lumbar spine bone mineral density. Improvers had an age mean of 5.21 years greater than decliners (P= 0.01) and a mean duration difference since the menopause of 5.1 years compared with decliners (P= 0.007). Conclusion This combined continuous preparation of hormone replacement therapy improves not only trabecular bone but prevents compact bone loss, and the data suggest that the therapeutic range of 17 beta-oestradiol is between 200 pmol/L and 350 pmol/L. [source] SURGICAL SITE MARKING DOES NOT AFFECT STERILITYANZ JOURNAL OF SURGERY, Issue 8 2008John Rooney Background: In 2005, surgical site marking became mandatory in Australia, with the introduction of the first Australian guidelines to prevent wrong site surgery. It has been our experience that most surgical site marking occurs with the use of a non-sterile marking pen, which has been used on multiple patients and there is little information in the published work about the effects of surgical site marking carried out in this fashion. Our aim was to determine whether the sterility of a surgical site was affected by surgical site marking with a non-sterile surgical marking pen. Methods: Both forearms of 20 volunteers would simulate surgical sites. Surgical site marking was carried out on right forearms with the same non-sterile surgical marking pen, whereas left forearms were unmarked controls. Microbiology swabs were taken from both forearms before, and after, skin sterilization with 10% povidone,iodine. Routine cultures were carried out on the swabs after sodium thiosulphate was used to deactivate residual iodine. Cultures were assessed for growth after 5 days. Results: One of the 20 marked forearms and 15 of the 20 unmarked forearms had bacterial growth on cultures before skin sterilization (P < 0.1). After sterilization with iodine, no bacterial growth occurred in the cultures of the swabs taken from the marked or control arms. Conclusion: Surgical site marking carried out with a non-sterile surgical marking pen did not contaminate the surgical site. We recommend the practice of surgical site marking. [source] | ||||||||||
