Gangrenous Small Bowel Due to Reposition of Procidentia in an Elderly Woman.

Cureus 2022 May 15;14(5):e25013. Epub 2022 May 15.

General Surgery, Jawaharlal Nehru Medical College, Datta Meghe Institute of Medical Sciences, Wardha, IND.

Gynecologists are familiar with procidentia, a severe form of pelvic organ prolapse (POP) that includes herniation of the anterior, posterior, and apical compartments of the vagina, through the introitus. Usually, women with POP present with concerns of something coming out of the vagina, heaviness, discharge through the vagina, urinary complaints, and, rarely bowel, complaints. Intestinal obstruction secondary to procidentia is a rare complication and is seldom reported in the literature. Read More

Fluoroscopy-guided trans-urethral exchange of double-J ureteral stents.

BMC Urol 2022 Jun 15;22(1):85. Epub 2022 Jun 15.

Department of Radiology, Korea University Anam Hospital, 73, Goryeodae-ro, Seongbuk-gu, Seoul, Korea.

Background: For patients with malignant ureteral obstruction or stricture who require long-term internal drainage, plastic double-J stents (DJ stents) represent the mainstay of therapeutic strategies. DJ stents should be replaced at least once every 6 months to avoid infection or obstruction. Although DJ stents are generally replaced under cystoscopy, successful fluoroscopy-guided retrograde replacement of DJ stents in the interventional suite has been described in the literature.

The Use of Neutrophil Gelatinase-Associated Lipocalin (NGAL) as a Diagnostic and Prognostic Biomarker in Urinary Tract Obstruction: a Systematic Review.

Curr Urol Rep 2022 Jun 9. Epub 2022 Jun 9.

Urology Department, University Hospital Southampton, Southampton General Hospital, Tremona Road, Southampton, SO16 6YD, UK.

Purpose Of Review: The early recognition of urinary tract obstruction (UTO) is vital in order to prevent mortality and morbidity associated with an acute kidney injury (AKI) and progression to irreversible kidney damage. Urinary biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) have been recognised as an accurate tool in the timely diagnosis of AKI, but its role in the detection, prognosis and subsequent monitoring of a variety of obstructive uropathies has not yet been explored. We performed a systematic review of literature in accordance with Cochrane methodology from inception to August 2021. Read More

A Novel Technique with Ileal Mesentery to Reconstruct the Pelvic Peritoneum after Pelvic Dissection with End-Colostomy for Rectal Cancer.

Dis Colon Rectum 2022 May 25. Epub 2022 May 25.

Department of Gastrointestinal Surgery, West China Hospital, Sichuan University, Chengdu, 610041, Sichuan, China.

Background: After abdominoperineal resection, low anterior resection, and end-colostomy for lower rectal cancer, it is necessary to reconstruct the pelvic peritoneum to avoid small bowel obstruction, perineal hernia, and radiation enteritis in patients for whom postoperative radiotherapy is planned. However, pelvic peritoneal closure is technically difficult in patients who lack enough peritoneum to cover the defect or have received neoadjuvant radiation and have a rigid pelvis.

Impact Of Innovation: The impact of this innovation is to reconstruct the pelvic peritoneum with the distal ileal mesentery laparoscopically. Read More

Twist1 downregulation of PGC-1α decreases fatty acid oxidation in tubular epithelial cells, leading to kidney fibrosis.

Theranostics 2022 1;12(8):3758-3775. Epub 2022 May 1.

Department of Nephrology, Xijing Hospital, Fourth Military Medical University, No. 127 Chang le West Road, Xi'an, Shaanxi, 710032, China.

A deficiency of fatty acid oxidation (FAO) is the metabolic hallmark in proximal tubular cells (PTCs) in renal fibrosis owing to utilization of fatty acids by PTCs as the main energy source. Lipid accumulation may promote lipotoxicity-induced pathological injury in renal tissue. However, the molecular mechanism underlying lipotoxicity and renal tubulointerstitial fibrosis (TIF) remains unclear. Read More
