Shortages of benzathine penicillin for prevention of mother-to-child transmission of syphilis: An evaluation from multi-country surveys and stakeholder interviews.

Background: Benzathine penicillin G (BPG) is the only recommended treatment to prevent mother-to-child transmission of syphilis. Due to recent reports of country-level shortages of BPG, an evaluation was undertaken to quantify countries that have experienced shortages in the past 2 years and to describe factors contributing to these shortages.

Methods And Findings: Country-level data about BPG shortages were collected using 3 survey approaches.

A reproducible ex vivo model for transanal minimally invasive surgery.

Background: Rectal tumors can be excised through a number of minimally invasive transanal techniques including transanal excision, transanal endoscopic microsurgery, and transanal minimally invasive surgery (TAMIS). Specialty training is often required to master the nuances of these approaches. This study aimed to create a reproducible transanal excision training model that is suited for laparoendoscopic techniques.

Robot-assisted rectopexy and colpopexy for rectal prolapse.

Aim: This video demonstrates a technique for robot-assisted combined rectopexy with colpopexy, but without the use of mesh for rectal prolapse.

Methods: This case features a 61-year-old woman who presents with complaints of tissue protruding through her rectum and fecal incontinence. On examination, she was found to have circumferential, full-thickness rectal prolapse and perineal descent.

Treatment of refractory perianal fistulas with ligation of the intersphincteric fistula tract: preliminary results.

Several surgical options exist for management of fistula in ano. The goal of treatment is to achieve closure of the fistula while maintaining continence. Sphincter-sparing operations to close perianal fistulas include advancement flap, anal fistula plug, fibrin glue, and fistulectomy.

Preoperative chemotherapy does not increase morbidity or mortality of hepatic resection for colorectal cancer metastases.

Hepatic metastasis from colorectal cancer (mCRC) is best treated with a multidisciplinary approach. Conflicting data exist regarding the impact of preoperative chemotherapy on morbidity and mortality after hepatectomy. We hypothesized that preoperative chemotherapy does not adversely impact complications or mortality associated with hepatectomy.

Fate of Escherichia coli O157:H7 and Other Coliforms in Commercial Mayonnaise and Refrigerated Salad Dressing.

Commercial mayonnaise and refrigerated ranch salad dressing were inoculated at two levels with two strains of Escherichia coli O157:H7, a non-pathogenic E. coli , and the non-fecal coliform Enterobacter aerogenes . Results showed that at the high inoculation level (>10 colony forming units [CFU]/g) in mayonnaise stored at room temperature (ca.
