This integrative systematic review investigates the frequency, nature, and risk factors of complications following shoulder joint repair, encompassing arthroscopic rotator cuff surgery, labral stabilization, and arthroplasty. Synthesizing evidence from the last decade, findings indicate that while these procedures are generally successful, surgical complications occur in approximately 5% to 10% of primary cases, rising significantly in revision settings. Arthrofibrosis (stiffness) and persistent pain emerge as the most prevalent issues across all techniques, whereas periprosthetic infection (notably Cutibacterium acnes) and implant loosening are critical concerns in arthroplasty. Medical and anesthetic complications, such as venous thromboembolism and nerve-related events, remain relatively rare but are strongly influenced by patient-specific factors like advanced age, smoking, and diabetes. The review concludes that preoperative optimization and a high index of suspicion for low-grade infections are essential for improving long-term patient satisfaction and surgical longevity.

The present study compares three colon-targeted drug delivery systems; Eudragit S100-coated polymeric tablets, PLGA nanoparticles, and alginate hydrogel microspheres, developed for the controlled release of 5-Fluorouracil (5-FU). Each formulation was prepared and optimized using distinct carriers and evaluated under simulated gastrointestinal (GI) conditions to assess their physicochemical characteristics, release behaviour, and stability. The formulations were characterized for particle size, surface charge, encapsulation efficiency, and swelling index. Morphological analysis confirmed smooth coating in polymeric tablets, spherical uniformity in nanoparticles, and a porous structure in hydrogels. In vitro dissolution studies revealed minimal drug release in gastric conditions (≤2% at pH 1.2) and sustained release at colonic pH (7.4). PLGA nanoparticles showed the most controlled release profile, achieving 92.1 ± 2.4% cumulative release at 24 hours, compared with 100.0 ± 3.1% for polymeric tablets and 85.4 ± 2.1% for hydrogels. Kinetic modeling indicated that all systems followed diffusion-dominated release, with nanoparticles best fitting the Higuchi model (R² = 0.981). Stability studies confirmed nanoparticle integrity under prolonged acidic and neutral exposure, while hydrogels exhibited partial deformation. Overall performance analysis identified PLGA nanoparticles as the most efficient system, demonstrating superior acid resistance, encapsulation efficiency, and colon-specific release. These findings suggest that nanoparticle-based carriers offer significant potential for achieving predictable, site-specific, and sustained drug delivery to the colon.

A 2-year-old boy presented to the paediatric emergency department with a 5-day history of persistent high fever reaching 40°C, marked irritability, reduced oral intake, and non-productive cough. The child's mother reported onset of symptoms following a minor upper respiratory infection two weeks earlier, initially managed at home with oral paracetamol and later with oral antibiotics (amoxicillin) prescribed by a primary care physician, which failed to resolve the fever or other emerging symptoms. On examination, the child exhibited bilateral non-exudative conjunctival injection, strawberry tongue with red cracked lips, anterior cervical lymphadenopathy (right sided, 2 cm node), polymorphous erythematous rash across the trunk and extremities sparing the diaper area, and indurative oedema of the hands and feet. These findings fulfilled the diagnostic criteria for complete Kawasaki disease (KD), prompting immediate hospital admission for further evaluation and treatment.
