P44 A case of contact dermatitis caused by a NSAID's soluble agent

Yoshimi Kato
A fifty five year-old man had experienced itching sensation when he applied analgesic plasters for his lumbago. He tried to use several kinds of analgesic plasters, however he felt itching sensation whenever he used them. He applied a plaster containing ferbinac for his left elbow joint's pain on April 2003. On the next day, an itching erythema developed on the area where the plaster was applied. He was treated with a difluprednate ointment, and his dermatitis gradually improved. He visited our clinic for precise medical examination for finding out the causative agent of his dermatitis on May 13, 2003. We conducted 48 hours closed patch testing with the plaster he used and it's ingredients. He reacted positively to the plaster containing ferbinac and crotamiton 5%p that was used for dissolute the active drug. He also reacted positively to a cream containing ketoprofen, however he reacted negatively to ketoprofen 1%p. Crotamoton was also used in the ketoprofen cream. [source]

Primary malignant melanoma of the bladder

Abstract, Primary malignant melanomma of bladder is extremely rare: 18 cases are reported to date. An 82 year-old man underwent trans-urethral resection of bladder for a bleeding tumor of the posterior wall. Histological diagnosis was melanoma of the bladder. There was no history of previous or regressed cutaneous malignant melanoma. Margins of the bladder lesion contained atypical melanocytes similar to those commonly seen in the periphery of primary mucous membrane lesions. Clinical studies and radiological examinations were negative for other primary site of melanoma. The patient had a bladder recurrence that was consistent with primary tumor and died of widespread disease 9 months after diagnosis. [source]

Radiofrequency Catheter Ablation of Postinfarction Ventricular Tachycardia from the Proximal Coronary Sinus

VT Ablation from the Coronary Sinus. Optimum strategy for radiofrequency (RF) catheter ablation of ventricular tachycardia (VT) after inferior wall myocardial infarction (MI) that originates from the posteroseptal process of the left ventricle is not known. We describe a case report of a 57,year-old man who developed recurrent post-MI VT with ECG morphology consistent with this type of VT (i.e., left bundle branch block pattern with predominant R waves from V2 to V6 and left-axis deviation). Endocardial mapping and entrainment during VT demonstrated a critical isthmus of the reentrant circuit in the proximal coronary sinus. RF application terminated VT and rendered it noninducible.

Primary Cutaneous Immunocytoma Presenting with Diffuse Subclinical Involvement and Demonstrating Kappa and Lambda Light Chain Restrictions

C. Lorenzo
A 37 year-old man with primary cutaneous immunocytoma with lambda light chain restriction involving the left shoulder was treated with Rituxan with clinical resolution. Four years later, he presented with a six-month history of diffuse asymptomatic erythema. Physical examination revealed three grouped papules on the right upper arm and an irregular sclerotic patch with slight erythema superiorly on the left shoulder at the site of the initial tumor. There was no diffuse erythema. Biopsies were obtained from a papule on the right upper arm, the sclerotic patch on the left shoulder, and clinically uninvolved skin on the right anterior thigh. All three specimens showed a variably dense, predominantly periadnexal and perivascular dermal infiltrate of plasma cells and lymphocytes. The specimen from the right arm demonstrated kappa light chain restriction. The specimen from the right thigh showed lambda light chain restriction. Physical examination six weeks later demonstrated mottled erythema on the anterior thighs. Two biopsies were obtained from the right thigh. One showed immunocytoma. The other was unremarkable. The patient's primary cutaneous immunocytoma demonstrated two unusual findings: (1) histologic presence of tumor in clinically uninvolved and minimally involved skin; and (2) the presence of two distinct monoclonal populations.

Apparent Reactivation of a Fibrohistiocytic Proliferation with Features of Dermatofibroma and Dermatomyofibroma Following Systemic Immunosuppression

W.A. High
A 41 year-old man presented with an atrophic, hyperpigmented plaque on the right lower abdomen present since"birth". He denied any prior activity at the site, and had been told it was a "scar" from a prenatal insult. Six months earlier, he developed idiopathic focal sclerosing glomerulonephritis and was placed on 70 mg prednisone per day. He had not demonstrated evidence of lupus eythematosus. Shortly after beginning this regimen, erythematous and tender papules developed around the quiescent plaque. He had tapered his prednisone dose to 60 mg per day, but additional papules continued to erupt. An ellipse biopsy was performed which included a portion of the atrophic plaque and several surrounding papules. Histological examination revealed a proliferation of fibrohistiocytes between and amongst collagen bundles. In some areas, fibrohistiocytes entrapped collagen in a fashion reminiscent of a dermatofibroma. In other areas, particularly that of the atrophic plaque, the fibrohistiocytes were less numerous and more delicate in appearance. Scattered rudimentary fascicles were demonstrated. Adnexal structures were preserved. Immunohistochemical staining revealed the fibrohistiocytes to be positive for factor XIIIa and actin, but negative for desmin, CD34, S-100, procollagen I, and CD68. This lesion demonstrated unique clinical/histiological aspects not well characterized in the literature. [source]

Airway Management After Maxillectomy: Routine Tracheostomy Is Unnecessary,

Ho-Sheng Lin MD
Abstract Objectives/Hypothesis There is a paucity of data to guide the optimal management of the airway in patients after maxillectomy. The decision on whether a concomitant tracheostomy is needed is often dictated by the surgeon's training and experience. We reviewed our experience with maxillectomy to assess the need for tracheostomy in postoperative airway management. Study Design Retrospective analysis at a university hospital. Methods We identified 121 patients who underwent 130 maxillectomies between October 1990 and September 2001. Twenty-four of these were total (all six walls removed), 45 were subtotal (two or more walls removed), and 61 were limited (only one wall removed). Reconstruction ranged from none to microvascular free flap, with split-thickness skin graft being the most common reconstructive option. Results Only 10 tracheostomies (7.7%) were performed at the time of maxillectomy. These included four tracheostomies in patients who underwent bulky flap reconstruction, two tracheostomies in patients who underwent both flap reconstruction and mandibulectomy, one tracheostomy in a patient who underwent mandibulectomy, one tracheostomy in a patient with mucormycosis in anticipation of prolonged ventilatory support postoperatively, and two tracheostomies at the surgeons' discretion because of concern for upper airway edema. Among the 111 patients who underwent 120 maxillectomies without concomitant tracheostomy, 1 patient (0.9%), a 74 year-old man with oxygen-dependent chronic obstructive pulmonary disease, required repeat intubation on day 3 and again on day 10 after the surgery, because of respiratory failure; fiberoptic examination confirmed the absence of upper airway compromise. Conclusions The routine performance of tracheostomy in patients undergoing maxillectomy is unnecessary. Selective use of tracheostomy may be indicated in situations in which mandibulectomy or bulky flap reconstruction is performed or a concern for postoperative oropharyngeal airway obstruction because of edema or packing exists.

Refractory thrombotic thrombocytopenic purpura following influenza vaccination

ANAESTHESIA, Issue 4 2009
P. J. Dias
Summary Thrombotic thrombocytopenic purpura (TTP) is characterised by the systemic microvascular aggregation of platelets causing ischaemia of the brain and other organs. We describe the case of a 54 year-old man who presented with neurological signs, fever, severe thrombocytopenia, microangiopathic haemolytic anaemia and renal failure 5 days after receiving an influenza vaccination. He was diagnosed with acute refractory TTP caused by autoantibody-mediated ADAMTS-13 deficiency. He required stabilisation on the critical care unit before being successfully treated with 3 l plasma exchanges for 21 days and rituximab (MabThera®) at a dose of 375 mg.m,2, given weekly for a total of 4 weeks. Vaccination is an important part of preventative medicine and reduces morbidity and mortality. Only in a few rare cases has vaccination been associated with autoimmune pathology. We could find only one similar case report of thrombotic thrombocytopenic purpura following influenza vaccination. In addition to plasma exchange, rituximab appears to be effective and well tolerated in the treatment of refractory thrombotic thrombocytopenic purpura. [source]

Heparin-induced thrombocytopenia (HIT) causing pulmonary emboli during coronary intervention,

Ronny S. Jiji MD
Abstract Thrombotic complications of heparin-induced thrombocytopenia (HIT) can be devastating if not recognized and treated promptly. We describe an unusual case of rapid-onset HIT resulting in massive-bilateral pulmonary emboli in a 70 year-old man who developed chest pain during elective percutaneous coronary intervention (PCI). The diagnosis was made the following day after persistent chest pain and laboratory work demonstrating a new thrombocytopenia, a mildly elevated troponin, and positive DIC panel led to confirmatory imaging tests. HIT-related thrombosis should be considered in the differential diagnosis of chest pain in patients undergoing PCI. © 2008 Wiley-Liss, Inc. [source]
