Burn injuries are very painful for children, especially during dressing changes when the wound is cleaned and re-bandaged. This procedure, while necessary, can cause pain, fear, and distress that may make children afraid of future treatments. Virtual reality (VR) is a technology that uses a headset to show an immersive, interactive 3D world. It can distract children from painful medical procedures. This study aims to find out if using VR during burn dressing changes can reduce pain, fear, and behavioral distress in children aged 6 to 12 years. Half of the children will receive standard burn care plus VR distraction during their dressing change. The other half will receive standard care only. The study will take place at the Burns and Plastic Surgery Center, Mansoura University, Egypt. Children will be recruited from both inpatient wards and outpatient clinics. Pain will be measured using a number scale, fear using a faces scale, and distress will be observed throughout the procedure. It is expected that children who use VR will report less pain, show less fear, and display less distress during their dressing changes compared to children who receive standard care alone.

Thyroiditis includes inflammatory thyroid disorders such as Hashimoto's thyroiditis and subacute thyroiditis. These conditions may cause thyroid pain, neck tenderness, elevated inflammatory markers, thyroid dysfunction, fatigue, and recurrence. Current management includes observation, symptomatic treatment, nonsteroidal anti-inflammatory drugs, and corticosteroids. Although corticosteroids may be effective, relapse after tapering and treatment-related adverse effects remain limitations. Colchicine is hypothesized to reduce inflammatory activity and may improve biochemical and clinical recovery. This study will evaluate the efficacy and safety of low-dose colchicine compared with corticosteroid therapy and supportive care in adults with autoimmune or subacute thyroiditis.

This randomized clinical trial will evaluate the effect of using an enamel matrix derivative during immediate dental implant placement in the mandibular molar region.

Background: Carbetocin is an established single-dose uterotonic agent for postpartum hemorrhage prophylaxis at elective cesarean delivery. Despite its proven efficacy, many clinicians routinely add a supplemental oxytocin infusion following carbetocin administration without evidence-based justification. Concurrent oxytocin receptor stimulation may be redundant, counterproductive through receptor desensitization, or incrementally beneficial - a mechanistic uncertainty that remains unresolved in the published literature. Objectives: To determine whether carbetocin monotherapy (100 micrograms IV bolus plus placebo infusion) is non-inferior to carbetocin plus supplemental oxytocin infusion (10 IU over 4 hours) in preventing the need for additional uterotonic agents within 24 hours of elective cesarean delivery. Study Design: Prospective, randomized, double-blind, placebo-controlled, non-inferiority trial with an integrated pilot phase. Phase 1 (Pilot, n=60) establishes local feasibility and event rate. Phase 2 (Full trial, n=332) provides the definitive non-inferiority analysis. Participants: Women aged 18-45 years undergoing elective cesarean delivery under spinal anesthesia at Qassim University Medical City, singleton pregnancy at or beyond 37 weeks, ASA physical status II, preoperative hemoglobin 9 g/dL or more. Interventions: Group C (Monotherapy): Carbetocin 100 micrograms IV bolus plus placebo saline infusion 500 mL over 4 hours. Group C+O (Combination): Carbetocin 100 micrograms IV bolus plus oxytocin 10 IU in 500 mL saline over 4 hours. Primary Outcome: Proportion of patients requiring at least one additional uterotonic agent within 24 hours of delivery. Secondary Outcomes: Quantitative intraoperative blood loss by gravimetric measurement; total 24-hour blood loss; actual blood loss by Gross formula; hemoglobin and hematocrit changes; uterine tone scores by verbal numerical rating scale (0-10) at 2, 5, and 10 minutes; incidence of postpartum hemorrhage; blood transfusion requirement; hemodynamic profiles; adverse effects. Sample Size: 332 patients (166 per group), non-inferiority margin 10 percentage points, one-sided alpha 0.025, 80% power, estimated baseline event rate 10%, with 15% dropout allowance.

The goal of this clinical trial is to evaluate the effect of pelvic floor muscle exercises on primary post-micturition dribbling (PMD) in male patients aged 18 to 40 years. The main questions it aims to answer are: 1. Does pelvic floor muscle training reduce the severity and frequency of PMD as measured by the Hallym Post-Micturition Dribble Questionnaire (HPMDQ)? 2. Does pelvic floor muscle training reduce the amount of post-void residual urine as measured by a post-voiding pad test? Researchers will compare patients undergoing pelvic floor muscle training (Group A) with those performing non-targeted exercises (Group B) to see if targeted pelvic floor training is more effective in managing PMD symptoms and reducing urine leakage. Participants will: * Undergo random assignment to either pelvic floor muscle training or non-targeted exercise for 12 weeks * Complete baseline and follow-up assessments including: * Medical history and physical exam * Urine analysis and post-void residual measurement * International Prostate Symptom Score (IPSS) * Post-voiding pad test * Hallym Post-Micturition Dribble Questionnaire (HPMDQ)

The goal of this clinical trial is to evaluate the effectiveness and safety of low-intensity shockwave therapy (Li-SWT) for the treatment of overactive bladder (OAB) in adult women. The main questions this study aims to answer are whether Li-SWT improves overactive bladder symptoms and quality of life, and whether these improvements are sustained over a 12-month follow-up period, compared with standard medical therapy. Researchers will compare Li-SWT with oral solifenacin succinate, a commonly used antimuscarinic medication for OAB. Participants will be randomly assigned to receive either Li-SWT once weekly for 8 weeks or solifenacin 5 mg taken orally once daily for 12 months. All participants will complete symptom questionnaires and three-day voiding diaries and will undergo uroflowmetry, post-void residual measurement, and filling cystometry at specified time points during follow-up.

Breastfeeding is essential for infant survival and maternal health; however, many primipara women experience breastfeeding difficulties in the early postpartum period, particularly, latching difficulties, ineffective milk transfer, low breastfeeding self-efficacy and breast engorgement, which may compromise successful breastfeeding. Oketani massage is a non-pharmacological, cost-effective breast massage technique developed to enhance milk flow, improve maternal comfort during breastfeeding and reduce breast engorgement. This study aims to evaluate effect of Oketani massage on successful breastfeeding. Successful breastfeeding will be assessed through indicators of maternal latching technique, successful breastfeeding behavior and maternal breastfeeding self-efficacy. The findings of this study may support the use of Oketani massage as a supportive nursing intervention to promote successful breastfeeding outcomes in the early postpartum period
