Article Abstract

Osteogenesis imperfecta (OI) is a heritable connective tissue disorder characterized by defective type I collagen synthesis, leading to reduced bone strength and increased susceptibility to fractures, often with minimal trauma. Fractures involving the tibial tuberosity are rare and typically occur in adolescents during periods of rapid growth, usually following high-demand activities. We report a case of a 14-year-old male with type I OI who sustained a displaced tibial tuberosity avulsion fracture with epiphyseal and intra-articular extension (Salter-Harris type III, Ogden type IIIA) following low-energy trauma. Surgical management was undertaken via open reduction and internal fixation using partially threaded lag screws through a medial parapatellar approach, with precautions tailored to the patient's underlying bone fragility. Postoperative recovery was favorable, and the patient remained under multidisciplinary follow-up. This case emphasizes the importance of individualized surgical planning and technique in patients with OI to ensure stable fixation and minimize complications associated with bone fragility.

Objective: To describe the use of transcorneal iris photocoagulation (TCIP) to improve intraocular visualization of intended incision lines, reduce hemorrhage, and facilitate excision of pigmented iridal tumors in four canine eyes and one feline eye.

Materials And Methods: A Rhodesian Ridgeback (treated bilaterally), a German Shepherd, a Labrador Retriever, and a Scottish Fold underwent sector iridectomy due to rapidly growing, pigmented, raised, iridal tumors affecting 1/4-1/3 of the iris circumference (3- to 4-clock hours). A diode laser was used to delineate the intended sector iridectomy incision lines, approximately 1-2 mm away from the grossly visible tumor margins, with the aim of improving visualization to achieve tumor-free margins and reduce tissue handling/trauma.

Severe emphysema impairs lung function and quality of life in patients with Chronic Obstructive Pulmonary Disease (COPD). Despite optimized medical treatment and rehabilitation, some patients require lung volume reduction interventions (endoscopic or surgical). This study evaluates one-year outcomes of patients managed at the Emphysema Clinic of CHU Liège.

Small bowel diverticulosis is a rare and predominantly asymptomatic condition that mainly affects elderly individuals. Hemorrhagic complications, though rare, can be life-threatening. In cases of suspected bleeding, CT angiography is recommended to diagnose, localize, and assess the severity of the hemorrhage.

Cystic lesions of the head and neck encompass a wide spectrum of benign and malignant entities, which often presents diagnostic challenges as a result of the region's complex anatomy. Despite extensive literature, variability persists in diagnostic strategies and approaches. Fine-needle aspiration biopsy is a commonly used and highly effective method for the initial assessment of these lesions by offering a minimally invasive technique to collect cellular material for diagnostic evaluation.
