[Abdominal manifestations of Henoch-Schönlein purpura in adults. A retrospective study of 23 cases]. / Atteintes digestives du purpura rhumatoïde de l'adulte. Etude d'une série rétrospective de 23 patients.

INTRODUCTION: Gastrointestinal manifestations of Henoch-Schönlein purpura (HSP) in adults may be severe. Data about treatment are controversial and the outcome is seldom described. METHODS: Twenty-three patients with gastrointestinal manifestations of HSP (ACR criteria) were retrospectively studied. We proposed to use clinical and radiological (CT scan) severity scores to assess the usefulness and the efficacy of corticosteroid therapy. RESULTS: Age at onset ranged from 16 to 80 years (median 39). Gastrointestinal manifestations included abdominal pain (96%), vomiting (52%), gastrointestinal bleeding (39%), diarrhoea (13%) and intestinal obstruction (9%). Scores of disease clinical severity were calculated in 21 patients. Fourteen, three and four had severe, intermediate and mild disease, respectively. Ten patients in the group with severe clinical involvement underwent CT scan that showed severe radiological involvement (parietal thickening of several bowel loops of the same segment or several segments with ileal involvement). Eleven patients out of 14 with clinically severe disease were given corticosteroids. Two patients out of three with intermediate and three patients out of four with mild scores also received corticosteroids. The others received supportive care. In-patients with severe clinical scores, gastrointestinal symptoms improved within 2 days when they were given corticosteroids and within 12.3 days without corticosteroids (p<0.0002). No side effect was observed with steroid therapy. CONCLUSION: These results suggest that corticosteroids may reduce abdominal symptoms of HSP in adults with clinically severe disease. They are safe when CT scan is performed.

[Nephrogenic fibrosing dermopathy treated with extracorporeal photopheresis: role of gadolinium?]. / Dermopathie néphrogénique fibrosante traitée par photochimiothérapie extracorporelle: rôle du gadolinium?

BACKGROUND: Nephrogenic fibrosing dermopathy is a cutaneous and systemic sclerosis affecting patients with renal failure. CASE-REPORT: A 68-year-old man with renal insufficiency and on dialysis developed hardening of the skin and severe joint contractions. He had previously undergone angiography with gadolinium-containing contrast agents. A skin biopsy confirmed nephrogenic fibrosing dermopathy. The patient was treated by oral steroids followed by extracorporeal photopheresis. An improvement was seen after 12 cycles. DISCUSSION: Treatment of nephrogenic systemic fibrosis is not codified and is normally based on the methods used for other forms of systemic sclerosis. Six cases of patients showing improvement under extracorporeal photopheresis have been published. The physiopathology of the disease is unknown. Gadolinium could act as a triggering agent by attracting circulating fibrocytes in the dermis of patients. Medical authorities recommend avoidance of gadolinium in patients with advanced kidney failure unless strictly necessary.

[Lingual tuberculosis revealing disseminated tuberculosis]. / Tuberculose disséminée révélée par une localisation linguale.

INTRODUCTION: Tuberculous lesions of the oral cavity are uncommon. Most of cases are secondary to pulmonary disease and the primary form is rare. EXEGESIS: We report the case of a 64 year-old man, smoker, presenting a chronic ulcer of the tongue, with anorexia and important weight loss. The biopsy of this ulcer showed granulomatous inflammation and Langhans type giant cells, without necrosis. Ziehl-Nielsen stain was negative. Pulmonary lesions were subsequently detected (chest X-ray, CT-scan) and the disseminated tuberculosis was confirmed by a positive culture with acid-fast bacilli in urine, blood, and pulmonary sample. Antituberculosis treatment resulted in the complete resolution of the oral lesion. CONCLUSION: Biopsy for histopathological diagnosis, acid-fast stains and culture, is essential to determine the exact nature of chronic oral ulceration to distinguish between oral malignancy, infectious (syphilis), traumatic, or aphthous ulcers. Tuberculosis of the tongue is a difficult diagnosis. However it should be searched for because treatment usually results in a rapid recovery.
