Association of systemic lupus erythematosis and myasthenia gravis. A new case report

The association of myasthenia gravis (MG) and systemic lupus erythematosus (SLE) is a quite rare one. We report here one case and try to discuss the physiopathologic mechanisms and also the clinical, evolutive and therapeutic features of this morbid association. It's the case of a woman of 43 years old followed in our department since 1999. The patient has been treated by corticosteroids (prednisone) with monthly administered cyclophospamide pulses. Nine months lately, she develops a diplopia with a ptosis, a dysphagia and a muscular weakness. The treatment was mainly based on intravenous immunoglobulins. The later evolution was favourable. The coexistence of SLE and MG is not casual. It must be considered in every lupic patient developing neuromuscular troubles.     

Une atteinte du système nerveux central au cours de la sclérodermie systémique

Systemic sclerosis is a connective disease usually known to spare the central nervous system. This has been much debated by recent imaging studies. We report a 56-year-old woman followed-up for systemic sclerosis since 2005. Four years later, she presented with cerebellar and pyramidal syndrome. Magnetic resonance imaging showed signs of cerebral vasculitis. The patient was treated by corticosteroids and cyclophosphamide pulses followed by azathioprine for maintenance therapy. Clinical and radiological outcomes were favourable. In patients with systemic sclerosis and neurological symptoms, abnormalities in the cerebral magnetic resonance imaging may, in the absence of another obvious etiology, indicate a central nervous system involvement associated with this systemic disorder.     

Idiopathic portal hypertension associated with celiac disease: one case

We describe for the first time a case of idiopathic portal hypertension (IPH) in a 31 year old patient with coeliac disease (CD). She had splenomegaly, pancytopenia and an unexplained portal hypertension in the absence of any histological abnormalities of the liver. The diagnosis of coeliac disease was based on histological and serological data. Treatment included a splenectomy and a splenorenal shunt.     

Knowledge,attitudes & barriers to condom use among female sex workers and truck drivers in Uganda: a mixed-methods study

Background

There is limited documentation on knowledge, attitudes and barriers to condom use among female sex workers (FSWs) and truck drivers (truckers).

Objective

To explore knowledge, attitudes and barriers to condom use among FSWs and truckers operating along major transport corridors in Uganda

Methods

Structured questionnaires were administered to explore FSWs'' and truckers'' knowledge of and attitudes towards condom use among 259 FSWs and 261 truckers. Qualitative data were collected on barriers to condom use using focus group discussions. Quantitative data were analyzed using SPSS while qualitative data were audio-recorded, transcribed and thematically analyzed.

Results

Condom knowledge was high with 97% of FSWs and 95% of truckers agreeing with the statement, “using condoms properly and consistently reduces risk of HIV infection”. Attitudes towards condom use were generally favorable with 91% of FSWs and 82% of truckers agreeing with the statement, “condom use is the best method of HIV prevention”. Qualitative findings show that poverty, refusal to use condoms by male partners, alcohol use before sex and beliefs that condoms ‘kill the mood for sex’ remain key barriers to consistent condom use.

Conclusions

Consistent condom use among FSWs and truckers is still hampered by economic and relationship factors.     

Physicians' perspectives on the uncertainties and implications of chromosomal microarray testing of children and families

Chromosomal microarray analysis (CMA) has improved the diagnostic rate of genomic disorders in pediatric populations, but can produce uncertain and unexpected findings. This article explores clinicians' perspectives and identifies challenges in effectively interpreting results and communicating with families about CMA. Responses to an online survey were obtained from 40 clinicians who had ordered CMA. Content included practice characteristics and perceptions, and queries about a hypothetical case involving uncertain and incidental findings. Data were analyzed using nonparametric statistical tests. Clinicians' comfort levels differed significantly for explaining uncertain, abnormal, and normal CMA results, with lowest levels for uncertain results. Despite clinical guidelines recommending informed consent, many clinicians did not consider it pertinent to discuss the potential for CMA to reveal information concerning biological parentage or predisposition to late‐onset disease, in a hypothetical case. Many non‐genetics professionals ordering CMA did not feel equipped to interpret the results for patients, and articulated needs for education and access to genetics professionals. This exploratory study highlights key challenges in the practice of genomic medicine, and identifies needs for education, disseminated practice guidelines, and access to genetics professionals, especially when dealing with uncertain or unexpected findings.     

Tuberculomes cérébraux : à propos de six cas

Introduction

Despite the resurgence of tuberculosis, partly due to HIV infection, central nervous system involvement remains rare, accounting for only 2 to 5% of all tuberculosis forms.

Patients et method

We report six cases of brain tuberculomas occurring in patients free of HIV infection and hospitalized between 2001 and 2006 in the internal medicine department of a Tunisian military hospital (Tunis).

Results

Four patients had an underlying defect. Headache, fever, consciousness disorders, deficit disorder or cerebellar syndrome are the main symptoms. Tuberculomas were multiple and disseminated in four cases and localized in the brain stem in two cases. Positive diagnosis could be established in two cases on the basis of the pathology results of a brain biopsy or detection of Mycobacterium tuberculosis in the cerebrospinal fluid; the diagnosis was presumptive in the other cases. Five patients recovered under antituberculosis treatment maintained on average 13 months (11 to 16 months). Steroid treatment was associated in five patients and tapered off for four to six weeks. One 78-year-old diabetic patient died in a context of cachexia with multiple organ failure.
