[Emotional expressiveness and development of schizophrenia: a reply to the work of Vaughn].

The influence of family climate in the course of schizophrenia has been empirically established. However research has been so far limited to the Anglo-American culture and there are reasons to think that straight forward extrapolation to own our culture may not be totally justified. Consecqently a replication of Vaughn's (Vaughn et al, 1984) has been carried out with a sample of 60 schizophrenic patients in Valencia. Relapse rate was not predicted by EE status or by any EE scale-score according to British original criteria. As the cut-off point was changed from six or more critical remarks to four or more, then the relapse rate was significantly different between high and low EE groups. The study confirms the link between EE-status and relapse rates over nine months but is also underlines the need to take into account cultural differences when it comes to establish cut-off scores.

Immunohistochemical location of S-100 and glial fibrillary acidic proteins in salivary gland pleomorphic adenomas.

The S-100 protein is a low molecular weight protein which has been isolated mainly in mammalian brain cells. Glial fibrillary acidic protein is one of the five types of intermediate filaments described to date. We used immunohistochemical methods to study the expression in this patterns of expression of these two proteins in pleomorphic adenoma of the salivary glands, in an attempt to explain their tumor and to elucidate the origin of this complex neoplasm of the salivary glands.

[Digestive cytomegalovirus disease in AIDS patients].

BACKGROUND: In this paper we study the digestive manifestations of cytomegalovirus (CMV) in AIDS patients. Also, we evaluate the antiviral treatment and the necessity of maintenance therapy. METHODS: Retrospective review of medical charts of all patients with AIDS and digestive CMV disease diagnosed and followed-up since 1983 to december 1993. RESULTS: Of 720 AIDS patients, 96 presented a CMV disease. Among them, 30 patients (31%) complained digestive manifestations. These were 26 males and 4 females, mean age: 37.4 y-old. Risk factors for HIV were: 13 homosex and 12 intravenous drug abusers. Average of time between AIDS diagnosis and digestive CMV disease: 13.4 months. Fourteen patients had esophagitis, 9 proctocolitis, 3 hepatitis, 3 pancreatitis, 2 gastric ulcerations, one small bowel disease and other an oral ulceration. Two patients had a concomitant CMV chorioretinitis. CD4 lymphocytes were below 0.05 x 10(9)/l in 29 patients. Twenty-four patients received antiviral treatment during the acute disease period, with a clinical curation rate of 60%. Seven patients received maintenance therapy and remained free of CMV disease until death. Eleven patients didn't received maintenance treatment. Of them, one patient presented a digestive relapse and two developed a CMV chorioretinitis. Mortality in the first month from diagnosis was 23% and the median of survival time for patients who cured and initial episode of digestive CMV disease was 208 days, wether or not the patient received maintenance therapy or not. CONCLUSIONS: One third of ours patients with AIDS and CMV infection have a digestive disease. This CMV digestive disease appears in patients with a severe immunosuppression. Acute phase mortality was 23%. The median survival was 7 months, independently or receiving maintenance treatment or not.

[Autoimmune hepatitis with antibodies against liver cytosol (anti-LC1)].

Antibody against liver cytosol (anti-LC1) was proposed in 1988 as a new and very specific immunoserologic marker of autoimmune hepatitis of childhood and young age. In adults, anti-LC1 might be masked by the presence in serum of anti-LKM1, usually associated with antibodies to hepatitis-C virus. We report the case of a 60-year-old woman who had active chronic hepatitis not related to infection by hepatitis C virus, with autoantibody reacting against liver cytosol as the unique marker of autoimmune hepatitis. Treated with corticosteroids (prednisone, 1 mg/kg per day), coagulation disorder, bilirubin, transaminase activity and immunoglobulins normalized in the following months. A year and a half later, autoantibodies anti-LC1 and p-ANCAs were no longer detected. We have only found one report of a young patient with anti-LC1 autoimmune hepatitis who had cirrhosis and portal hypertension, in national publications.
