Transmission of Clostridium difficile spores in isolation room environments and through hospital beds

The aim of this study was to determine the dissemination of Clostridium difficile (CD) spores in a hospital setting where the potassium monopersulfate‐based disinfectant Virkon^TM was used for cleaning. In the initial part of the study, we sampled 16 areas of frequent patient contact in 10 patient rooms where a patient with CD infection (CDI) had been accommodated. In the second part of the study, we obtained samples from 10 patient beds after discharge of CDI patients, both before and after the beds were cleaned. In the first part, CDspores were isolated in only 30% of the rooms. In the second part, which focused on transmission to hospital beds, C. difficile was found in four of 10 beds either before or after cleaning. In conclusion, in both parts of the study, we demonstrated a moderate spread of CD spores to the environment despite routine cleaning procedures involving Virkon^TM.     

Infections by multidrug-resistant Gram-negative Bacteria: What's new in our arsenal and what's in the pipeline?

The spread of multidrug-resistant bacteria is an ever-growing concern, particularly among Gram-negative bacteria because of their intrinsic resistance and how quickly they acquire and spread new resistance mechanisms. Treating infections caused by Gram-negative bacteria is a challenge for medical practitioners and increases patient mortality and cost of care globally. This vulnerability, along with strategies to tackle antimicrobial resistance development, prompts the development of new antibiotic agents and exploration of alternative treatment options. This article summarises the new antibiotics that have recently been approved for Gram-negative bacterial infections, looks down the pipeline at promising agents currently in phase I, II, or III clinical trials, and introduces new alternative avenues that show potential in combating multidrug-resistant Gram-negative bacteria.     

Robotic transhiatal excision of epiphrenic diverticula

An epiphrenic oesophageal diverticulum is most commonly a pulsion diverticulum which develops consequent to protrusion of mucosa through the muscular wall of the distal oesophagus. Most of them are associated with underlying oesophageal motility disorders. The predominant symptoms are dysphagia with regurgitation, and sometimes retrosternal pain, if accompanied by spasm of the oesophagus. Surgical management is recommended for symptomatic patients. Traditional procedures include thoracotomy or laparotomy with excision of the diverticula, but these are associated with high morbidity. Laparoscopic approach is a safe treatment option associated with lesser morbidity. Here, we present a case of epiphrenic diverticulum which was treated by the robotic approach without any complication. There was also no associated motility abnormality in our case so fundoplication was not done. Robotic surgery is a useful tool while operating near the hiatus and gastro-oesophageal junction. We consider transhiatal robotic approach as a safe and easy approach for surgery of epiphrenic diverticulum.
