Background/objective: To draw a hint towards two simple modifications that could potentially decrease the complication rate.
Patients And Methods: It was a single center, single operator and retrospective study. All patients with severe hypospadias operated according to koyanagi with or without modifications were presented. The surgical technique was described. Complications like fistula, stenosis, dehiscence and urethral diverticulum were studied.
Results And Limitations: Nineteen patients were included and presented in a chronological manner. The first four patients were operated according to the original koyanagi technique. The next 15 patients were operated according to koyanagi and the urethroplasty was covered by a tunica vaginalis flap. In 10 of them, glanduloplasty was done primarily and in the last 5 patients, glanduloplasty was done as a secondary procedure. The complication rates were 100% in the original koyanagi group, and 0% in the subset were glanduoplasty was deferred.
Conclusions: Systematically covering the urethroplasty with a tunica vaginalis flap and deferring the glanuloplasty might ameliorate the results of the koyanagi technique.

Simple Approach to Cosmetic Medial Epicanthoplasty: A Modification of the Skin Redraping Method.
Ann Plast Surg
February 2025
From the ThankYou Plastic Surgery Clinic, Seoul, Republic of Korea.
Background: The medial epicanthal fold is a common ethnic trait in East Asian faces, and there is a significant demand for its correction for cosmetic reasons. Numerous epicanthoplasty techniques have been proposed; however, visible scarring and unnatural canthal shapes have been challenges. This study aimed to introduce a simpler approach for medial epicanthoplasty to address these issues and evaluate its outcomes.

The conductivity of AgNWs electrodes can be enhanced by incorporating Ag grids, thereby facilitating the development of large-area flexible organic solar cells (FOSCs). Ag grids from vacuum evaporation offer the advantages of simple film formation, adjustable thickness, and unique structure. However, the complex 3D multi-component structure of AgNWs electrodes will exacerbate the aggregation of large Ag particles, causing the device short circuits.

Low anterior resection syndrome (LARS) is a challenging complication following sphincter-preserving rectal surgery, characterized by bowel dysfunctions such as urgency, frequency, and incontinence. This case series investigates the potential role of lactose intolerance in exacerbating LARS symptoms. Three patients who developed LARS after rectal resections showed persistent symptoms despite conventional management with bulking agents, physiotherapy, and loperamide.

Aqueous zinc ion batteries are often adversely affected by the poor stability of zinc metal anodes. Persistent water-induced side reactions and uncontrolled dendrite growth have seriously damaged the long-term service life of aqueous zinc ion batteries. In this paper, it is reported that a zinc sulfide with optimized electron arrangement on the surface of zinc anode is used to modify the zinc anode to achieve long-term cycle stability of zinc anode.

Background: High-precision and broad-range pH detection is critical for health status assessment, such as signal transduction, enzyme activity, endocytosis, and cell proliferation and apoptosis. Although pH-responsive ratiometric fluorescent probes offer an effective pH monitoring strategy, their preparation often requires multi-step modification and decreases fluorescence efficiency and stability. Herein, we developed a simple method to prepare fluorescent Si dots with dual emission centers for high-precision and broad-range pH monitoring, and the detection of urease based on pH-responsive Si dots and pH monitoring in living cell was further explored.
