[Chickenpox prevention in patients at risk with a special immunoglobulin].

Chickenpox, which normally is an innocuous disease in children, may cause serious sequelae in immunocompromised hosts. An open prospective study is presented, that comprised 96 of such patients. They were treated with 0,2 ml/kg Varicella-Zoster-Immunoglobulin (VZIG) prophylactically or after exposure. The immunoglobulin was given in between 72 hours after known contact, newborns received the injection at the day of delivery. After that the patients were followed for six weeks for documentation and assessment of protection. In 85 (88,5%) cases there was no manifestation of varicella. 10 patients showed mild forms of the disease; 3 of these had got the preparation within the recommended time gap of 72 hours after exposure. One child died from varicella pneumonia and haemorrhage. In this case the preparation had only been given 10 days after contact.

Eosinophilic gastroenteritis with malabsorption, extensive villous atrophy, recurrent hemorrhage and chronic pulmonary fibrosis.

A patient with diffuse eosinophilic gastroenteritis, associated with progressive chronic interstitial pulmonary fibrosis, was followed for 29 years. His major symptoms were recurrent gastrointestinal bleeding, anemia, diarrhea, malabsorption, and increasing respiratory insufficiency. Multiple jejunal biopsies revealed eosinophilic infiltration and extensive villous atrophy. Results of a lung biopsy and pulmonary function tests were consistent with chronic interstitial pulmonary fibrosis. His gastrointestinal symptoms responded to steroid therapy, but he died of progressive respiratory insufficiency. At autopsy, villous atrophy was noted to extend throughout the whole extent of the small intestine in association with multiple "pseudopolypoidal" inflammatory lesions.

Cerebral phaeohyphomycosis caused by an Exophiala species.

A 45-year-old woman was found to have cerebral phaeohyphomycosis caused by an Exophiala species. The portal of entry of the fungus remained unknown. Despite surgery and antimycotic therapy the patient died from circulation failure. The fungus is compared to several related Exophiala species.

Pharmacobezoar: an evolving new entity.

Pharmacobezoars, bezoars comprised of medications, are unusual entities. Medications reported to cause bezoars include aluminum hydroxide gel, enteric-coated aspirin, sucralfate, guar gum, cholestyramine, enteral feeding formulas, psyllium preparations, nifedipine XL, and meprobamate. They most often occur, as do bezoars of any type, in a background of altered motility or anatomy of the gastrointestinal tract. Bowel hypoactivity, dehydration, and concomitant use of anticholinergics and narcotis appear to contribute to the propensity for bezoar formation by aluminum hydroxide gel and Isocal. The hygroscopic properties of psyllium and guar gum appear to contribute to their propensity to form bezoars. Insolubility of the carrying vehicle of enteric-coated aspirin and nifedipine is the setting in which these medications form bezoars. In contrast to nonmedication bezoars, pharmacobezoars may produce additional symptoms, those related to the release of their active ingredients. In patients with suspected gastrointestinal tract emptying problems, whether esophageal, gastric, small bowel, or colonic, the astute clinician should consider pharmacobezoar in the differential diagnosis.

Invasion of cranial nerves and brain stem by herpes simplex virus inoculated into the mouse tongue.

Herpes simplex virus type 1 (HSV) of a highly or slightly neuropathogenetic strain was inoculated into the tongues of mice. After appropriate survival times, the animals were killed and portions of the facial and trigeminal nerves as well as the brain stem were examined with virus isolation and immunocytochemistry for the presence of HSV. Both virus strains were demonstrated in the geniculate and trigeminal ganglia and in the CNS portion of the facial and trigeminal nerves, as well as in various brain stem areas including the trigeminal tract and nucleus, the facial and hypoglossal nuclei, and nuclei in the reticular formation. The results indicate that HSV is transported to the CNS by efferent and afferent axons of the tongue and subsequently via transneuronal passage to various brain stem nuclei. These findings provide an anatomic basis for a putative relationship between HSV and cranial nerve dysfunction.

Awareness and knowledge of fibromyalgia among French rheumatologists and general practitioners.

OBJECTIVES: Fibromyalgia is a chronic disorder characterized by widespread musculoskeletal pain and fatigue. Its prevalence is estimated to be at 3.4% in women and 0.5% in men. It is a major cause of morbidity. Our objective was to evaluate, using a self-questionnaire sent by mail, the level of knowledge of French physicians, general practitioners, and rheumatologists on fibromyalgia and to analyse their therapeutic approach. METHODS: The demographic characteristics of a sample of general practitioners and rheumatologists were compared to those of the overall data available. This comparison demonstrated the good representativeness of our sample. RESULTS: Fibromyalgia was considered as a disease by 23% of rheumatologists and 33% of general practitioners. While on average, each rheumatologist followed 30 fibromyalgia patients, each general practitioner followed 6.1 patients (i.e., 2 to 5% of their practice's patient base). Among rheumatologists, 6.4% made no distinction between this disease and depression vs. 13.1% of general practitioners. The diagnosis of fibromyalgia was made based on tenderness that occurs in precise, localized areas of the body (trigger points) by 94% of rheumatologists and 79.1% of general practitioners. Of general practitioners and rheumatologists, 93.7% and 73.7% respectively, have not received any medical school training on fibromyalgia or chronic fatigue syndrome. CONCLUSION: Given the lack of medical school training and continuing professional education concerning fibromyalgia (rare use of pain rating scales, confusion in the classification of rheumatic diseases), there is an urgent need to initiate an explicit teaching effort on chronic pain, and on fibromyalgia in particular.
