Objective: To analyze the results of ultrasound (US)-guided needle puncture, aspiration and lavage in the treatment of symptomatic calcific tendinitis of the rotator cuff.
Design And Patients: Atraumatic pain in 61 shoulders of 58 patients was resistant to conservative therapy. The average age of the treated patients was 42 years (range 26-49 years), follow-up was 12 months, and the mean diameter of the calcifications was 1.6 cm (range 1.1-2.9 cm). With US guidance and local anesthesia, two needles were placed within each calcification. The calcification was punctured 10-15 times and saline solution injected and aspirated using the needles until the aspirate was free of calcific particles.
Results And Conclusions: Based on radiographs at 1 year follow-up. 74% (45 of 61) of the calcifications decreased, including 28% (17 of 61) which disappeared totally, and 26% (16 of 61) were unchanged. Calcifications with a faint or absent shadow on US proved to be nearly liquid (slurry calcification in 93% (14 of 15) of cases and could be aspirated. Clinical results were excellent in 74% (45 of 61), moderate in 16% (10 of 61) and poor in 10% (6 of 61) of cases. US offers technical advantages over fluoroscopy, and the typical US image of a slurry calcification helps to select the most suitable patients for aspiration treatment. The results are comparable with those using fluoroscopic guidance.

Introduction: Although the administration of activated charcoal (AC) is considered safe, the associated risk of pulmonary aspiration explains certain reluctance of physicians to use this procedure. The objective of this study was to analyse the rate of pulmonary aspiration in children receiving AC after accidental ingestion of a toxic substance.
Methods: We carried out a substudy of a multicentre prospective registry-based cohort study including children presenting with acute poisoning to 58 paediatric emergency department (EDs) members of the Spanish Society of Pediatric Emergency Medicine between 2008 and 2022 on certain previously designated days.

Background: Pulmonary tuberculosis (PTB) accounts for 85% of all reported tuberculosis cases globally. Extrapulmonary involvement can occur in isolation or along with a pulmonary focus as in the case of patients with disseminated tuberculosis (TB). EPTB can occur through hematogenous, lymphatic, or localized bacillary dissemination from a primary source, such as PTB and affects the brain, eye, mouth, tongue, lymph nodes of neck, spine, bones, muscles, skin, pleura, pericardium, gastrointestinal, peritoneum and the genitourinary system as primary and/or disseminated disease.

Background: The incidence of revision shoulder arthroplasty continues to rise, and infection is a common indication for revision surgery. Treatment of periprosthetic joint infection (PJI) in the shoulder remains a controversial topic, with the literature reporting varying methodologies, including the use of debridement and implant retention, single-stage and 2-stage surgeries, antibiotic spacers, and resection arthroplasty. Single-stage revision has been shown to have a low rate of recurrent infection, making it more favorable because it precludes the morbidity of a 2-stage operation.

BACKGROUND Pembrolizumab, a programmed cell-death protein-1 (PD-1)-targeting antibody, extends survival in cancer patients but may cause lung injury as a side effect. This immunotherapy enhances the immune system's ability to recognize and eliminate cancer cells. However, its immunomodulatory action can sometimes lead to immune-related adverse events, including lung injury.
