ReviewTranexamic acid in acute upper gastrointestinal bleeding.
The effect of the antifibrinolytic substance, tranexamic acid, has been studied in 5 double-blind, randomized, placebo-controlled trials in patients with acute upper gastrointestinal bleeding. The results of these trials have varied with regard to blood transfusion requirements and the frequency of operations. All of the studies have shown lower mortality in patients treated with tranexamic acid. Thus tranexamic acid would seem to be indicated in acute upper gastrointestinal bleeding.

ReviewFactors that might influence the outcome of studies on the aetiology and epidemiology of acute pelvic inflammatory disease.
An overview is presented of the various factors that might influence the outcome of aetiological and epidemiological studies of pelvic infections in women. Some diversities of opinion in these respects might be explained by i.a. inprecise definitions, lack of simple and specific diagnostic methods, differences in patient selection and laboratory techniques.

Gut peptide secreting tumours originate most commonly from the pancreatic Islets of Langerhans. Tumours at a variety of other sites have also been shown to synthesize and release these peptides, reflecting the wide distribution of the peptide secreting cells of the diffuse neuroendocrine system. ⋯ This may explain the lack of clinical sequelae in association with tumours such as the somatostatinomas. The clinical features, methods of diagnosis, localisation and treatment of these tumours will be discussed.
