Overview of osteo-articular involvement in systemic sclerosis: Specific risk factors, clinico-sonographic evaluation, and comparison with healthy women from the French OFELY cohort.

Osteoarticular involvement in systemic sclerosis (SSc) is frequent and varied. Data are scarce on the prevalence and risk factors of osteoporosis (OP). We aimed to assess clinical parameters, radiological parameters, US articular involvements, and the frequency of OP and evaluate SSc-specific risk factors.

Outbreak of enterically-transmitted hepatitis due to hepatitis A and hepatitis E viruses.

Background/aims: One hundred and eleven patients with acute hepatitis and 61 controls were investigated for hepatitis serological markers in order to determine the viral etiology of cases involved in a waterborne epidemic of hepatitis observed in 1993 in Djibouti, Republic of Djibouti (East Africa). These cases occurred both in indigenous Djiboutians, and in French soldiers and their families in Djibouti. A retrospective study of the viral etiology of acute hepatitis cases observed in French soldiers and relatives living in Djibouti during the 3-year period preceding the epidemic was also undertaken.

[Occurrence of non-Hodgkin's lymphoma in chronic myeloid leukemia].

The authors report the case of a 42-year old woman who developed chronic myelocytic leukemia with Philadelphia chromosome followed, 21 months later, by malignant follicular lymphoma with small cleaved cells and giant cells. This case is comparable to the other associations of acute or chronic myelocytic and lymphocytic blood diseases previously published. Several pathogenic theories are reviewed.

[Severe and extensive algodystrophies and malignant tumors. Apropos of 4 cases].

The authors report on 4 cases of particularly severe and extensive reflex neurovascular dystrophy, whose clinical course was marked by the onset of a malignant tumor, without any sign of improvement in the reflex neurovascular dystrophy, despite various therapeutic regimens, until the patient's death from malignancy. At this time, the authors compiled a total of 63 case reports (4 of which were reported) and have proposed a classification to differentiate 4 types of disorders in combination according to whether there is a very probable, probable, or possible link or whether the combination is strictly a coincidence. The pathogenic mechanism remains a mystery, when a link is observed; but it never corresponds to criteria to describe a paraneoplastic disorder.

[Neurogenic tumor of the anterior mediastinum. An uncommon diagnosis: neurofibroma of the vagus].

Case report of an endothoracic neurofibroma of the left vagus nerve, presenting as an anterior mediastinal mass in a 62 years old man without other signs of Recklinghausen's disease. Rarity of such cases is noted. Previously published sixty one reports are studied.
