Duodenal Fibrosis Mimicking Neoplastic Obstructive Hepatopathy in the Setting of Lynch Syndrome.

Intestinal fibrosis is a rare complication of chronic inflammation resulting from various etiologies, including surgery, abdominal radiation, and inflammatory bowel disease. Consequences of intestinal fibrosis include intestinal dysmotility, malabsorption, and obstruction. Patients with Lynch syndrome are predisposed to developing intestinal adenocarcinoma including in the small intestines which typically require intra-abdominal procedures that expose them to fibrogenic triggers.

Unmodified gold nanoparticles for direct and rapid detection of Mycobacterium tuberculosis complex.

Objectives: This work aims to develop rapid nano-gold assay prototypes for specific detection of Mycobacterium tuberculosis complex (MTBC).

Design And Methods: Spherical gold nanoparticles (AuNPs, 14nm) were synthesized by citrate reduction method and characterized by spectrophotometry and SEM. MTB 16s rDNA regions were amplified by PCR and amplicons were detected using genus- and species-specific oligotargeters and AuNPs.

A nosocomial transmission of crimean-congo hemorrhagic fever to an attending physician in North Kordufan, Sudan.

Background: Crimean-Congo hemorrhagic fever (CCHF), a tick-borne disease caused by Crimean-Congo hemorrhagic fever virus (CCHFV), is a member of the genus Nairovirus in the family Bunyaviridae. Recently, CCHFV has been reported as an important emerging infectious viral pathogen in Sudan. Sporadic cases and multiple CCHF outbreaks, associated with nosocomial chain of transmission, have been reported in the Kordufan region of Sudan.
