To provide the definition, causes, and current recommendations for workup and treatment of acute infectious colitis in adults, a common medical problem of diverse cause.

The management of acute colitis in adults depend upon establishment of cause. Most forms of infectious colitis are treatable with antimicrobials. Multiplex polymerase chain reaction (PCR) followed by guided culture on PCR-positive pathogens can often confirm active infection while standard culture methods provide isolates for antibiotic susceptibility testing, subtyping, and Whole Genome Sequencing.

Patients with colitis may be suffering from a range of etiologies including infectious colitis, neutropenic colitis, drug-induced colitis, and inflammatory bowel disease. The present review was prepared to provide an approach to prompt diagnosis and management of acute colitis to prevent severe complications (e.g. dehydration and malnutrition, or toxic megacolon) and provide recommendations for antimicrobial therapy.

Trehalose metabolism appears to play a role in the pathogenicity of some microbes. It has been claimed that trehalose consumption may be a risk factor for Clostridioides difficile infection (CDI), but the evidence for a causal link is contentious.

Epidemic ribotypes of C. difficile harbour mutations or have acquired extra genes that mean these strains can utilize lower concentrations of bioavailable trehalose, providing a competitive metabolic advantage in some CDI animal models. By contrast, evidence has emerged to show that trehalose-induced microbiota changes can help protect/reduce CDI in other models. In addition, C. difficile trehalose metabolic variants are widespread among epidemic and nonepidemic ribotypes alike, and the occurrence of these trehalose variants was not associated with increase disease severity or mortality.

Currently, there is no proven causal association between the incidence or severity of human CDI and the presence of trehalose metabolism variants. Furthermore, microbial metabolism reduces trehalose bioavailability, potentially removing this competitive advantage for C. difficile trehalose metabolism variants. Taken together, trehalose consumed as part of a normal diet has no increased risk of CDI.

The gut-associated lymphoid tissue (GALT), the bulk of which is located in the ileo-colonic region comprises the lymphoid cells of the gastrointestinal tract and confers specific immunological responses. Repetitive antigenic stimulation of these cells predispose to a monoclonal proliferation of this tissue and the eventual development of lymphoma. The gastrointestinal tract is the most commonly involved site of extranodal lymphomas. This review will focus primarily on lymphomas of the ileo-colonic region (defined as the terminal ileum, the colon, and the rectum). We will discuss the epidemiology, pathogenesis, and presentation as well as current practices in diagnosis and management.

Despite the majority of the GALT to be located in the ileo-colonic region of the gut, the lymphomas in this location are relatively rare. However, the overall annual incidence of ileo-colonic lymphomas is steadily increasing. This entity has a varied spectrum of clinical presentations. selleck compound Ileo-colonoscopy with adequate targeted ent while surgery is indicated for emergency presentations. Adequate endoscopic surveillance tools are lacking, yet imperative to prevent recurrence and improve prognosis.
To assess long-term crystalline lens transparency in eyes implanted with phakic collamer intraocular lens (pIOL) with a central port and low postoperative vault for correction of myopia.

Clinica Baviera, Madrid, Spain.

Retrospective cross-sectional single-center study.

Using a noninvasive Fourier-domain swept-source anterior-segment optical coherence tomography system, shifts in myopic and astigmatic myopic eyes implanted with a pIOL with vaulting lower than 100 μm in miosis and over 4 years of follow-up were dynamically evaluated. Main outcome measures were pIOL dynamic vault (vault interval and vault range [VR]), crystalline lens density, and anterior subcapsular lens opacities. Crystalline lenses were examined under slitlamp microscopy, and lens density was evaluated using quantitative Scheimpflug images. Scheimpflug images were compared with a control group comprising eyes that were candidates for pIOL implantation.

The study population comprised 24 eyes from 16 patients previously implanted with a pIOL (5.82 ± 0.9 years) with central vault lower than 100 μm under photopically induced miosis. The mean vault value was 52 ± 19 µm under photopic light conditions and 113 ± 37 µm under scotopic conditions. The mean VR was 58 ± 24 μm. Anterior subcapsular lens opacities were found in only 1 eye (4.17%). The mean lens density was 7.94 ± 0.43, and no significant differences were observed compared with the control group.

Long-term low vaulting in eyes implanted with a pIOL with a central port for correction of myopia was associated with a low risk for developing anterior crystalline lens opacities.

Ultrasound-guided interscalene brachial plexus block (ISB) is used to control pain after shoulder surgery. Though effective, drawbacks include phrenic nerve block and motor block of the hand. The ultrasound-guided anterior approach to perform suprascapular nerve block (SSNB) may provide a good alternative.

To compare lung ventilation and diaphragmatic activity on the operated side in ISB and SSNB.

Randomised, controlled patient-blinded and assessor-blinded trial.

Outpatient surgical clinic with recruitment from June 2017 to January 2018.

Fifty-five outpatients scheduled for arthroscopic shoulder surgery were allocated randomly to receive SSNB or ISB. Technical problems with monitoring devices unrelated to the intervention led to exclusion of seven patients. The remaining 48 (n=24 in each group) were followed up for 24 h without drop-outs.

Patients received 10 ml of ropivacaine 1.0% wt/vol for both procedures.

Percentage lung ventilation on the operated side was the primary endpoint as assessed with electrical impedance tomography (EIT).
