Introduction: Dacryocystorhinostomy (DCR) is the commonest surgery for nasolacrimal duct obstruction. Inhibition of the scarring process within the anastomosis and rhinostomy site which has been attributed to the failure of this procedure, might improve the success rate of DCR. The objective of this study was to evaluate the outcomes of DCR with Mitomycin-C (MMC) and to compare the results of DCR with and without MMC.
Materials And Methods: A hospital based, prospective study was conducted in patients with primary acquired nasolacrimal duct obstruction. Standard conventional DCR was performed upto the level of creation of flaps. Application of MMC 0.2 mg/ml in and around the ostium and underneath the created flaps for two minutes was effected with cotton pledgets. The area was thoroughly washed with normal saline after removal of the pledgets. Rest of the surgery was completed as usual. The patients were followed up on the first postoperative day, one month and three months post surgery.
Results: A total of 60 cases, 30 in each group were allocated. The success rate of DCR with MMC was found to be 96.7% compared to 86.7% (p=0.35) in the DCR group at the end of three months duration.
Conclusions: Intraoperative application of MMC during conventional DCR surgery provides a comparatively higher success rate than DCR without MMC without posing any extra financial burden and adverse drug reaction to the patient.

Fertility in transgender and gender diverse people: systematic review of the effects of gender-affirming hormones on reproductive organs and fertility.
Hum Reprod Update

Amsterdam UMC, Location Vrije Universiteit Amsterdam, Centre of Expertise on Gender Dysphoria, Amsterdam, The Netherlands.
Background: Transgender and gender diverse (TGD) people seek gender-affirming care at any age to manage gender identities or expressions that differ from their birth gender. Gender-affirming hormone treatment (GAHT) and gender-affirming surgery may alter reproductive function and/or anatomy, limiting future reproductive options to varying degrees, if individuals desire to either give birth or become a biological parent.
Objective And Rationale: TGD people increasingly pursue help for their reproductive questions, including fertility, fertility preservation, active desire for children, and future options.

Introduction: Permanent implantation of a DF-4 implantable cardiac defibrillator (ICD) lead in the left bundle branch area (LBBA-ICD) is the next paradigm in amalgamating cardiac resynchronization therapy (CRT) and defibrillation. We systematically investigated feasibility/success rate, procedural caveats, and complications associated with a permanent DF-4 LBBA ICD implant and pertinent data at short-term follow-up.
Methods: We prospectively attempted implantation of 7 Fr Durata (Abbott, Chicago, IL, USA) single coil DF-4 ICD lead at the LBBA using a fixed-curve non-deflectable CPS locator delivery sheath.
