Infections and obesity: A multinational epidemiological study.

Viral infections have been associated with the aetiology of obesity in animal models. This study investigates the association between 7 serological markers of infections and body mass index (BMI) in a population based sample. Individuals (n=985, mean age 42+/-97 (28-55) y, mean BMI 25.

Achalasia in Iceland, 1952-2002: an epidemiologic study.

Limited epidemiologic information is available on achalasia in Northern European countries and worldwide. Achalasia has never been studied in Iceland. This study aimed to evaluate the epidemiology of achalasia in Iceland and compare the findings to other studies.

2,8-dihydroxyadeninuria: are there no cases in Scandinavia?

Homozygosity or mixed heterozygosity for mutations in the adenine phosphoribosyltransferase gene cause enzyme deficiency directing adenine through an alternative metabolic pathway. This results in the production of 2,8-dihydroxyadenine, which is actively secreted into the urine. 2,8-dihydroxyadenine is insoluble at physiological urinary pH but as marked supersaturation is possible the manifestations differ: there may be minimal consequences, there may be infiltration of the tubulointerstitial tissue with acute or chronic damage or there may be stone formation in the urinary tract.

Endobronchial actinomycosis secondary to a tooth aspiration.

We report a middle aged smoker with recurrent pneumonia caused by endobronchial actinomycosis secondary to a tooth aspiration. Unlike previously reported cases, our patient was not chronically debilitated. The case suggests that a follow-up bronchoscopy is beneficial after the initiation of antibiotic therapy for endobronchial actinomycosis.

The postdialytic rise in the plasma total homocysteine concentration is delayed.

Background/aims: The mechanism behind the uremic hyperhomocysteinemia has not been elucidated. Possibly, dialyzable uremic toxins play a role, e.g.
