The duodenal diverticulum is a relatively frequent entity whose diagnosis has been increased over time with the development of new diagnostic and exploratory techniques. Periampullary diverticula (PAD) were classified as type 1, 2, or 3 according to the position of the major papilla from the endoscopic view: type 1, the major papilla was located inside of the diverticula; type 2, the major papilla was located at the edge of the diverticula; type 3, the major papilla was located outside of the diverticula. Complications of duodenal diverticula include ulceration, bleeding, perforation and inflammation with intestinal obstruction.

Background: Spatial repellent products are used for prevention of insect bites, and a body of evidence exists on spatial repellent entomological efficacy. A new option for vector control, spatial repellent products are designed to release active ingredient into the air for disruption of human-vector contact thereby reducing human exposure to mosquito-borne pathogens. Clinical trials have shown spatial repellent epidemiological efficacy against Aedes-borne viruses but inconclusive outcomes against malaria.

A major insecticide resistance mechanism in insect pests is knock-down resistance (kdr) caused by mutations in the voltage-gated sodium channel (Vgsc) gene. Despite being common in most malaria Anopheles vector species, kdr mutations have never been observed in Anopheles funestus, the principal malaria vector in Eastern and Southern Africa, with resistance mainly being conferred by detoxification enzymes. In a parallel study, we monitored 10 populations of An.

In response to the article presented by Laura Rodríguez-Martínez et al., which discusses mucosal healing rates in celiac disease and the risk factors for persistent damage despite a gluten-free diet in adults, we present a review of biopsies from pediatric patients with celiac disease performed at our center between 2001 and 2020. Notably, there is a higher rate of mucosal healing compared to adults (83%), and factors such as age at diagnosis, histological involvement, and anti-tissue transglutaminase antibody levels at diagnosis do not appear to be significant risk factors, unlike in adults.
