Prostate cancer is the most common cancer in Dutch men and has a relatively good survival rate. Anorectal symptoms after irradiation of the prostate, including rectal blood loss and faecal incontinence, can have a serious impact on quality of life. On endoscopy, the Vienna Rectoscopy Score may reveal telangiectasia or other mucosal changes, but there may also be other causes of blood loss. Endoscopy or watchful waiting can be considered in patients with rectal bleeding. Sucralfate enemas, argon plasma coagulation and hyperbaric oxygen therapy are effective treatments. Increase in frequency of defaecation, faecal urgency or incontinence are related to decreased rectal compliance or to lowered anal resting pressure. Dietary measures can be considered in patients with faecal urgency or incontinence, but scientific evidence for the effectiveness of this is marginal. More accurate radiation techniques and the use of a spacer or endorectal balloon will probably contribute to maintaining rectal and anal function.

Safety and efficacy of low-powered holmium laser enucleation of the prostate in comparison with plasma kinetic resection of prostate.
Lasers Med Sci

Department of Urology Surgery, Beijing Traditional Chinese Medicine Hospital Affiliated to Capital Medical University, No.23 Art Museum Back Street, Dongcheng District, Beijing, 100010, China.
To compare the efficacy and safety of low-power holmium laser enucleation of the prostate (LP-HoLEP) with plasma kinetic resection of prostate (PKRP). Sixty-three patients treated with transurethral LP-HoLEP (observation group) and 68 patients treated with transurethral PKRP (control group) at Beijing Hospital of Traditional Chinese Medicine from November 2019 to November 2022 were retrospectively compared with regard to operation duration, intra-operative blood loss, prostate resection ratio, postoperative bladder irrigation time, postoperative indwelling urinary catheter time, postoperative urinary incontinence incidence, International Prostate Symptom Scale (IPSS), maximum urine flow rate (Qmax), and residual urine volume (RUV). In both groups, postoperative IPSS, Qmax, and RUV were significantly improved compared to preoperative values (P < 0.

Delayed cerebral ischemia, one of the most common complications following aneurysmal subarachnoid hemorrhage, was strongly related to poor patient outcomes. However, there are currently no clear guidelines to provide clinical guidance for post-craniotomy management. Our research aims to explore the association between cumulative blood pressure exposure during the early brain injury phase and the occurrence of delayed cerebral infarction and rebleeding following surgical aneurysm clipping.

Pediatr Surg Int
December 2024
Pediatric Surgery Department, Hospital Universitari i Politècnic La Fe, Av/Fernando Abril Martorell 106, 46026, Valencia, Spain.
Purpose: To assess the diagnostic performance of hemoglobin concentration for Meckel's diverticulum (MD) and evaluate if hemoglobin levels could be useful in the surgical decision-making process of children with lower gastrointestinal bleeding (LGIB).
Methods: Retrospective cohort study of children with LGIB attending the emergency department between 2011 and 2021. Episodes of LGIB were divided into two groups: MeckD (MD diagnosed by surgery) and non-MeckD.
Global, regional, and national burdens of intracerebral hemorrhage and its risk factors from 1990 to 2021.
Eur J Neurol

Department of Neurosurgery, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.
Background And Purpose: The aim of this study was to assess the intracerebral hemorrhage (ICH) burden in 204 countries and territories worldwide from 1990 to 2021, disaggregated by sex, age, and sociodemographic index (SDI) at the global, regional, and country levels.
Methods: Data from the 2021 Global Burden of Disease Study (GBD) were used to calculate age-standardized prevalence (ASPR), incidence (ASIR), death (ASDR), and disability-adjusted life year (DALY) rates for ICH. The estimated annual percentage change (EAPC) was used to assess time patterns.
Liver Cirrhosis as a Predictor of Infection Risk in Patients Undergoing Ventriculoperitoneal Shunt Surgery: A Retrospective Cohort Analysis from the Taiwan National Health Insurance Research Database (NHIRD).

Department of Neurosurgery, China Medical University Hospital, Taichung, Taiwan.
BACKGROUND Ventriculoperitoneal (VP) shunt surgery is a widely used procedure for managing hydrocephalus; however, postoperative infections remain a serious complication, increasing morbidity and mortality. Known risk factors include prior surgeries, steroid use, and concurrent procedures. However, the role of liver cirrhosis, a condition that compromises immune function and predisposes patients to infections, has not been fully investigated in the context of neurosurgery.
