[Ureteral stenosis in Wegener's granulomatosis. Case report].

INTRODUCTION: Ureteral stenoses in Wegener's granulomatosis are rare. They usually involve the pelvic portion of the ureter and are caused by vasculitic lesions or granulomatous inflammation. CASE: A 38-year-old woman with Wegener's granulomatosis was treated with corticosteroids and monthly intravenous cyclophosphamide pulses. After 4 months, urinary retention developed, accompanied by lumbar pain, associated with protenuria and hematuria, and related to bilateral ureteral stenoses. Treatment by endoscopic dilatation and double J stents led to with clinical and radiological improvement, while the medical treatment continued. CONCLUSION: Hematuria in patients with Wegener's granulomatosis suggests renal involvement, but ureteral stenoses must also be considered when these patients present hematuria or urinary tract infections. Surgery should be reserved for those patients in whom medical treatment is not rapidly effective.

[Shulman syndrome. A report of 4 cases and review of the literature].

The goal of this study is to report four cases of Shulman syndrome with a literature review. Shulman syndrome is a rare disorder recently considered a systemic disease. Our first case shows woody induration of the buttock and trunk with features of morphea. The diagnosis of eosinophilic fasciitis, suspected on hypereosinophilia, was confirmed by histological findings of muscle biopsy. In the second and the third case, the induration affected arms and legs. Obiouvs streneous exercise was noted in the third patient. Those patients fullfiled the criteria of eosinopfilic fasciitis. Visceral involvement consisted on restrictive lung function defects on the second case and oesophageal hypokinesia in the third case. In the fourth case, there was a scleroderma-like on the extremitis with extension to abdomen. Erythrocyte sedimentation rate was normal. Histological findings confirm the diagnosis of eosinophilic fasciitis. All patients were treated with general steroids at high doses associated to cimetidine in the second patient. Once therapy ended, relapses occur in escond and third cases.

[Hyperprolactinemia in systemic lupus erythematosus. A prospective study of 38 cases].

OBJECTIVE: To study prospectively the serum prolactin concentrations among patients with systemic lupus erythematosus and their possible relationship to disease activity and manifestations. METHODS: Serum prolactin levels were measured by radioimmunoassay in 38 patients with systemic lupus erythematosus and 22 age matched controls. Patients with known secondary causes for hyperprolactinaemia, such as pregnancy, lactation, prolactinoma and taking medications known to induce prolactin secretion, were excluded from the study. Demographic, clinical and laboratory features of the patients were obtained. Patients were divided into two subgroups according to their disease activity. Mean prolactin levels from both groups were compared using student test, and prolactin from patients with systemic lupus erythematosus was correlated with variables of disease activity, including the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). RESULTS: Mean prolactin levels were higher in patients with systemic lupus erythematosus (15.4) than healthy controls (9.83); however, the difference did not reach statistical significance (p=). Hyperprolactinemia was found in 24 patients with systemic lupus erythematosus and 5 controls. The frequency of hyperprolactinaemia in systemic lupus erythematosus group was higher than healthy controls. No significant difference in mean prolactin levels was found between patients with active versus inactive disease (18.9 vs 18.5). CONCLUSION: Hyperprolactinaemia occurred significantly in patients with systemic lupus erythematosus, but did not correlate with disease activity.

Esophageal involvement in Behcet's disease.

Esophageal involvement in Behcet's disease is very rare, and normally is observed as aphtosis and esophagitis, but serious complications such as erosions, perforations, and stenosis may occur. We carried out this prospective study to evaluate the prevalence of esophageal involvement in Behcet's disease and to establish if routine endoscopy and/or manometry are necessary. Twenty-three patients who fulfilled the diagnostic criteria of the international study group for Behcet's disease were enrolled. None were taking drugs or had disease that might produce esophageal abnormalities or alter any existing changes due to the Behcet's disease itself. Twenty- three patients underwent esophagogastroduodenoscopy by a single observer. Esophageal biopsies were performed in thirteen patients and esophageal manometry in twenty. At the beginning of the study, the disease activity was defined by the presence of more than one symptom related to Behcet's disease, and upon the classification of Behcet's disease. Of the twenty three patients enrolled two were excluded from final analysis because of the presence of hiatus hernia. Thus, 13 men and 8 women, ranging in age from 20 to 63 years with a mean age of 36.2 years were included. Ten patients (47.6%) had active disease and four (19%) complained of upper gastrointestinal symptoms at the time of the study. Fourteen patients had endoscopic, manometric and/or microscopic abnormalities. Esophageal manometry was performed in twenty patients and was abnormal in 7 cases (35%). Esophageal biopsies were done in 13 patients and revealed histopathological abnormalities in 5 cases. Microscopic findings showed vasculities in one case, and non-specific inflammatory infiltration mainly consisting of neutrophils in 4 cases. Our results suggest that the prevalence of esophageal involvement in Behcet's disease is rather high and occur even in asymptomatic patients, but that this usually does not result in specific abnormalities.

Heparin use during pregnancy.

The use of anticoagulants in pregnancy is problematic. In this focus, the authors reviewed the problems associated with the use of vitamin K antagonist during pregnancy. Then, they presented the general considerations on the use of unfractioned heparin and low molecular weight heparin during pregnancy. Finally they established the therapeutic recommendations for anticoagulation during pregnancy including treatment and prophylaxis of venous thromboembolism, anticoagulation of pregnant women with mechanical heart valves and the management of pregnant women with antiphospholipid antibodies and multiple pregnancy losses.
