Purpose: To evaluate the effectiveness of transperineal urethrosphincteric block (TUSB) in providing analgesia during visual internal urethrotomy for patients with anterior urethral strictures.
Patients And Methods: A total of 26 consecutive patients scheduled for elective visual internal urethrotomy for symptomatic urethral stricture were considered for this prospective study. Twenty-four patients agreed to participate in the study. Their demographics and medical conditions were recorded. Twenty-five percent of the patients had comorbid conditions that would have put them at high risk for general anesthesia. All patients had TUSB as the primary method of analgesia, using 1% lidocaine. Postoperatively, patients were asked to score the severity of the pain experienced during TUSB and during the transurethral surgery on a scale from 0 to 10. Postoperative adverse effects and the need for sedation or additional analgesia were recorded. All patients rated their overall satisfaction with the analgesia.
Results: Patient mean age was 43.5 years (range 26-71 years). The mean pain score during instillation of the transperineal block was 1.9 (range 0-3), and for visual internal urethrotomy was 1 (range 0-5). No sedation, narcotics, or additional analgesia were required and no postoperative adverse effects were encountered. Ninety-two percent of the patients were very satisfied with the method of analgesia.
Conclusion: TUSB is a safe and effective method of local analgesia for visual internal urethrotomy in patients with anterior urethral strictures, and is particularly suitable for those at high risk of general anesthesia.

Latarjet procedure versus iliac crest autograft transfer for anterior shoulder instability: a systematic review and meta-analysis of comparative studies.
J Orthop Surg Res

Department of Orthopedics, Hospital of Chengdu Office of People's Government of Tibetan Autonomous Region (Hospital.C.T.), Chengdu, 610041, People's Republic of China.
Background: Anterior shoulder instability with glenoid bone loss presents a challenge in orthopedic surgery. The Latarjet and iliac crest bone graft transfer (ICBGT) procedures are commonly employed for its management, but direct comparative evidence is insufficient.
Methods: Following PRISMA guidelines, a comprehensive search of PubMed, EMBASE, Cochrane Library, and Web of Science was conducted.
Background: To evaluate the associations between anatomical changes and visual outcomes after membrane peeling in eyes with different stages of idiopathic epiretinal membrane (iERM) using optical coherence tomography angiography (OCTA).
Methods: All iERM eyes were graded into four stages based on the presence of ectopic inner foveal layers (EIFL) and underwent 23-gauge vitrectomy combined with ERM and internal limiting membrane (ILM) peeling, while their fellow eyes were treated as the control group. OCTA was used to measure retinal thickness(RT), foveal avascular zone (FAZ)-related parameters and superficial and deep capillary plexus (SCP and DCP) layers using 6 × 6 mm scans before, 1 month and 3 months after surgery.
Charlson comorbidity index has no incremental value for mortality risk prediction in nursing home residents with COVID-19 disease.
BMC Geriatr

Julius Center for Health Sciences and Primary Care, University Medical Center Utrecht, Utrecht University, Utrecht, The Netherlands.
Background: During the COVID-19 pandemic, nursing home (NH) residents faced the highest risk of severe COVID-19 disease and mortality. Due to their frailty status, comorbidity burden can serve as a useful predictive indicator of vulnerability in this frail population. However, the prognostic value of these cumulative comorbidity scores like the Charlson comorbidity index (CCI) remained unclear in this population.

Purpose: Myocardial injury, indicated by an elevation of high-sensitive cardiac Troponin (hs-cTnT), is a frequent stroke-related complication. Most studies investigated patients with ischemic stroke, but only little is known about its occurrence in patients with intracerebral hemorrhage (ICH). This study aimed to assess the frequency, predictors, and implications of myocardial injury in ICH patients.
