Adult coeliac disease within a defined geographic area in Sweden. A study of prevalence and associated diseases

An epidemiologic study of coeliac disease in a geographically defined area of Sweden showed that the prevalence was 95.5/10(5) inhabitants aged 15 years or more. The highest prevalence, 178/10(5) inhabitants, was found in the age group 65-74 years. The lowest prevalence, 39/10(5) inhabitants, was found in patients aged 15-24 years. Among the associated diseases an especially high incidence of associated thyroid disease was observed: thyrotoxicosis occurred in 5.0% and hypothyroidism in 5.8% of the patients.     

Localization of arboviral antigen in brain tissues from patients with encephalitis

Brain tissues from 38 patients with a clinical suspicion of encephalitis or encephalopathy were examined by two immunoenzymatic techniques for the detection of arboviral antigen. Group B arboviral antigen was identified in 23 of these tissues. This simple method could be used for the diagnosis of the causal agent of encephalitis.     

Splenic release of amino acids in man assessed by arterial and venous blood sampling in situ

The splenic arteriovenous differences in plasma amino acid concentrations were assessed in situ by peroperative sampling in 11 patients undergoing splenectomy because of benign and malignant hematologic diseases. The total difference was about 250 mumol/l, which suggests that the spleen contributes about 11 mumol/100 g spleen/min of amino acids to the portal vein. This means that the liver extraction of amino acids may be at least 10% greater than previously believed.
