Purpose: Acute gastrointestinal bleeding is a common emergency. Tranexamic acid (TXA) reduces clot breakdown by inhibiting the action of plasmin and has been shown to reduce the need for blood transfusion in trauma, surgical procedures, and upper gastrointestinal bleeding. This study examined the efficiency of intravenous TXA in patients with acute lower gastrointestinal bleeding.

- The study investigated whether antibiotics influence the development of anal fistulas after surgery for perianal abscesses, hypothesizing that they do not have an effect.
- Conducted as a single-blinded randomized trial, patients were divided into two groups: one received antibiotics post-surgery and the other did not, with outcomes measured over one year.
- Results showed no significant difference in the formation of anal fistulas (16.3% vs 10.2%) or recurrent abscesses (9.2%) between the two groups, concluding that antibiotics do not impact these complications.
A consanguineous Israeli Bedouin kindred presented with an autosomal-recessive nonlethal phenotype of severe psychomotor retardation and extrapyramidal signs, dystonia, athetosis and ataxia, mild axial hypotonia, and marked global dementia with defects in verbal and expressive communication skills. Metabolic workup was normal except for mildly elevated blood lactate levels. Brain magnetic resonance imaging (MRI) showed increased density in the putamen, with decreased density and size of the caudate and lentiform nuclei.
