Unlabelled: Despite the success of dacryocystorhinostomy (DCR) in the treatment of lacrimal drainage system (LDS) obliteration and the use of medical and surgical methods to prevent its recurrence, the number of relapses reaches 37%. The main etiological factor leading to this pathology is partial (stenosis) or complete obstruction of the ostium.
Purpose: To study the effectiveness of endonasal balloon dacryoplasty in partial or complete obstruction of dacryocystorhinostomy ostium.
Material And Methods: The study involved 122 patients (127 cases) with relapse after endonasal endoscopic dacryocystorhinostomy performed 6 months to 3 years ago to treat partial or complete obstruction of lacrimal sac neck. Patients of the 1 group (41 cases) underwent endonasal balloon dacryoplasty, patients of the 2 group (42 cases) underwent endonasal balloon dacryoplasty with bicanalicular silicone stenting, patients of the 3 group (44 cases) underwent revision endonasal endoscopic dacryocystorhinostomy with bicanalicular silicone stenting.
Results: After 12 months follow-up, positive results were observed in 85.7% of cases with ostium stenosis and 80.0% of cases with complete obstruction of the ostium among group 1 patients; in 86.4% of cases with ostium stenosis and 85.0% of cases with complete obstruction of the ostium among group 2 patients; and in 81.0% of cases with ostium stenosis and 82.6% of cases with complete obstruction of the ostium among group 3 patients.
Conclusion: The obtained results give grounds to recommend inclusion of endonasal balloon dacryoplasty in the standards of treatment for patients with partial (stenosis) and complete obliteration of dacryocystorhinostomy ostium.

Background: Joubert syndrome (JS) is an autosomal recessive disorder with a distinctive mid-hindbrain malformation known as the "molar tooth sign" which involves the breathing control center and its connections with other structures. Literature has reported significant respiratory abnormalities which included hyperpnea interspersed with apneic episodes during wakefulness. Larger-scale studies looking at polysomnographic findings or subjective reports of sleep problems in this population have not yet been published.

Background: Aggressive angiomyxoma (AAM) is a rare benign mesenchymal tumor known for its aggressive behavior and high recurrence rates, with male cases of AAM being less frequently reported. This study presents a rare case of primary prostatic AAM characterized by a prostatic urethral mass obstructing the bladder outlet, resulting in acute renal dysfunction.
Case Description: The 51-year-old male patient presented with lumbar pain, nausea, frequent urination, urgency, and incomplete urination.
Testicular mapping-guided sperm retrieval upfront microTESE in non-obstructive azoospermia: a comparison of sperm retrieval, pregnancy and live-birth rates.

University of Washington, Seattle, WA, USA.
Background: Sperm extraction by Microscopic Testicular Sperm Extraction (microTESE) has become the standard of care for sperm retrieval (SR) in men with non-obstructive azoospermia (NOA) but is costly and has a 40-50% chance of failure. Fine needle aspiration mapping (FNAM) can be performed prior to microTESE as a predictor of success to reduce the likelihood of failure to retrieve sperm but there is limited evidence that directly compares these methods. The objective of this study was to compare success rate of SR, pregnancy, and live birth rates in men who underwent upfront microTESE versus FNAM.
