Enteric duplication cyst of the tongue in a newborn: A case report and literature review.

Enteric duplication cysts (EDCs) are congenital anomalies. We report the case of a 5-day-old girl with a 2.0 cm congenital oral mass in the tongue, an extremely uncommon site of EDC. The tongue mass was resected without complication; microscopic findings were characteristic of an EDC, and the patient is doing very well. The English literature was researched for the cases of single congenital oral cavity masses diagnosed prenatally or at birth as EDC or EDC-like lesions. Cystic lesions of the oral cavity partially lined by gastrointestinal epithelium, without teratoma features, have received several names. Similarities between EDC and EDC-like lesions favor the idea of one lesion with several morphologies manifest along a spectrum and that the necessity for EDC diagnosis of the smooth muscle coat criteria could be re-evaluated to improve the categorization of these lesions and better understand the pathogenic mechanism.

Gallbladder microbiota variability in Colombian gallstones patients.

INTRODUCTION: Gallbladder stones are a very frequently occurring condition. Despite bile bactericidal activity, many bacteria have been detected inside the gallbladder, and gallstones facilitate their presence. Between 3% and 5% of the patients with Salmonella spp. infection develop the carrier stage, with the bacteria persisting inside the gallbladder, shedding bacteria in their feces without signs of infection. The aim of this study was to isolate bacteria from Colombian patients with gallstones, using standard culturing methods, and to identify Salmonella spp. carriers by molecular techniques. METHODOLOGY: A total of 149 patients (120 female and 29 male) diagnosed with gallstones who underwent cholecystectomy and who did not have symptoms of acute inflammation were included. Gallbladder tissue and bile were cultured and used for DNA extraction and Salmonella spp. hilA gene detection. RESULTS: Of the 149 patients 28 (19%) had positive cultures. Twenty-one (75%) patients with positive cultures were from Medellin's metropolitan area. In this geographical location, the most frequent isolations were Pseudomonas spp. (38%), Klebsiella spp. (23%), and Proteus spp. (9%) in addition to unique cases of other bacteria. In Apartado, the isolates found were Enterobacter cloacae (50%), Raoultella terrigena (32%), and both Enterobacter cloacae and Raoultella terrigena were isolated in one (18%) male patient. Five (3.3%) of the 149 patients had positive polymerase chain reaction (PCR) results for the hilA gene of Salmonella spp., all of whom were female and residents of the Medellín metropolitan area. CONCLUSIONS: The gallbladder microbiota variability found could be related to geographical, ethnic, and environmental conditions.
