A middle-aged man arrives from a nursing facility to the emergency department with urinary retention and abdominal pain. A bladder scan was performed to identify the amount of urine in the bladder. Multiple attempts were made to place a urinary catheter without difficulty, but no urine was identified. When several attempts are made to insert a urinary catheter without success of urinary output, one must stop and rule out other causes. This case study outlines the etiology, diagnostics tests, and management of a patient with urinary retention.

Introduction And Importance: Myiasis is an overlooked public health issue, with urogenital myiasis (UGM) being particularly rare, as evidenced by only 59 reported cases worldwide from 1975 to 2017. There is a notable scarcity of cases involving patients with prolonged catheter use related to SCI. The interaction of SCI with the complications associated with indwelling urinary devices is less frequently discussed in prior literature.

Resorcinol is a widespread substance used in a large variety of manufacturing industries, including cosmetics, with endocrine-disrupting activity on the thyroid function. The aim of the present study was to develop and validate a sensitive, selective and robust method to quantify resorcinol in urine and thereby assess hairdressers' occupational exposure. As resorcinol is mainly excreted in urine as glucuronide or sulfate forms, the first step consisted in hydrolyzing urine samples with a β-glucuronidase-arylsulfatase enzyme for 16 h.

Background: Anal fistula surgery often leads to postoperative pain, which can hinder recovery and negatively impact patients' quality of life. This prospective, randomised, controlled trial (RCT) aims to investigate the efficacy of acupuncture in alleviating postoperative pain and reducing the usage of analgesic medications following anal fistula surgery.
Methods: This single-centre, patient-blinded, assessor-blinded, placebo-controlled randomised controlled trial (RCT) will be conducted at a tertiary referral hospital.
