Haemostatic spray in the management of acute nonvariceal upper gastrointestinal bleeding in children: A single-centre experience in Singapore.

Introduction/objectives: Haemostatic spray (HS; Hemospray) is a powder agent for endoscopic haemostasis in patients with acute upper gastrointestinal bleeding (UGIB). It has been shown to be effective and easy to administer. However, published data on efficacy and safety in children remain scarce.

Utilizing the Subunit Concept to Achieve Better Outcomes in Lower Limb Reconstruction: A Clinical Experience in an Asian Population.

Background: The goals of reconstruction have progressed from filling a defect to enhancing function and aesthetic appearance. We aimed to achieve better aesthetic and functional outcomes in terms of shoe fitting and mobility. This is accomplished via a classification of the subunits and aesthetic considerations of the lower limb.

Observation of Subdiffusive Dynamic Scaling in a Driven and Disordered Bose Gas.

We explore the dynamics of a tuneable box-trapped Bose gas under strong periodic forcing in the presence of weak disorder. In absence of interparticle interactions, the interplay of the drive and disorder results in an isotropic nonthermal momentum distribution that shows subdiffusive dynamic scaling, with sublinear energy growth and the universal scaling function captured well by a compressed exponential. We explain that this subdiffusion in momentum space can naturally be understood as a random walk in energy space.

Clinical profile, referral trends, and real-world application of vibration-controlled transient elastography in children with non-alcoholic fatty liver disease in Singapore.

Background And Aim: Pediatric non-alcoholic fatty liver disease (NAFLD) is a progressive disorder that is increasing in incidence globally. The study aims to describe the clinical profile and longitudinal outcome, including the utility of vibration-controlled transient elastography (VCTE), in children with NAFLD at a single tertiary liver unit in Singapore.

Methods: Retrospective review of patients aged 0-18 years referred for NAFLD from 2003 to 2020 was conducted.

Management of Male Infertility with Coexisting Sexual Dysfunction: A Consensus Statement and Clinical Recommendations from the Asia-Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA).

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients' factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region.

Conquering Educational Mountains: Maintaining a Radiology Clinical Education Track.

Establishing a clinical education track as part of a radiology residency is essential in shaping future radiology educators. Many obstacles will be encountered while starting, maintaining, and improving these educational pathways. Hurdles may include recruiting suitable residents for the track, recruiting and supporting faculty advisors, sustaining long-term resident engagement, counteracting educational exclusivity, and providing adequate time and financial support.

Results of the 2021-2022 Survey of the American Alliance of Academic Chief Residents in Radiology.

Rationale And Objectives: An annual survey of chief residents in accredited North American radiology programs is conducted by the American Alliance of Academic Chief Residents in Radiology (ACR). Special topics surveyed for the 2021-2022 academic year were procedural competency and virtual radiology education in the COVID-19 pandemic. The purpose of this study is to summarize the 2021-2022 ACR chief resident survey.

The Frog Sign Revisited.

The frog sign is a classic physical examination finding of typical atrioventricular nodal re-entrant tachycardia. We present the case of a 78-year-old man with recurrent, symptomatic supraventricular tachycardia referred for ablation in whom the frog sign was observed during physical examination.

Impact of Varicocele Repair on Semen Parameters in Infertile Men: A Systematic Review and Meta-Analysis.

Purpose: Despite the significant role of varicocele in the pathogenesis of male infertility, the impact of varicocele repair (VR) on conventional semen parameters remains controversial. Only a few systematic reviews and meta-analyses (SRMAs) have evaluated the impact of VR on sperm concentration, total motility, and progressive motility, mostly using a before-after analytic approach. No SRMA to date has evaluated the change in conventional semen parameters after VR compared to untreated controls.

Agreement of the Newly Developed Moyers' Equations and Moyers' Tables.

Objective:  This study aimed to develop the Moyers' prediction equation to be used with tooth widths predicting app on smartphone.

Materials And Methods:  Four equations were developed separately for sex and dental arches. Internal validation with Moyers' table was finished.

Consensus and Diversity in the Management of Varicocele for Male Infertility: Results of a Global Practice Survey and Comparison with Guidelines and Recommendations.

Purpose: Varicocele is a common problem among infertile men. Varicocele repair (VR) is frequently performed to improve semen parameters and the chances of pregnancy. However, there is a lack of consensus about the diagnosis, indications for VR and its outcomes.

Post-Vasectomy Semen Analysis: Optimizing Laboratory Procedures and Test Interpretation through a Clinical Audit and Global Survey of Practices.

Purpose: The success of vasectomy is determined by the outcome of a post-vasectomy semen analysis (PVSA). This article describes a step-by-step procedure to perform PVSA accurately, report data from patients who underwent post vasectomy semen analysis between 2015 and 2021 experience, along with results from an international online survey on clinical practice.

Materials And Methods: We present a detailed step-by-step protocol for performing and interpretating PVSA testing, along with recommendations for proficiency testing, competency assessment for performing PVSA, and clinical and laboratory scenarios.

Antisperm Antibody Testing: A Comprehensive Review of Its Role in the Management of Immunological Male Infertility and Results of a Global Survey of Clinical Practices.

Antisperm antibodies (ASA), as a cause of male infertility, have been detected in infertile males as early as 1954. Multiple causes of ASA production have been identified, and they are due to an abnormal exposure of mature germ cells to the immune system. ASA testing (with mixed anti-globulin reaction, and immunobead binding test) was described in the WHO manual 5th edition and is most recently listed among the extended semen tests in the WHO manual 6th edition.

MIRAGE Syndrome Caused by a c.3406G>C (p. Glu1136Gln) Mutation in the Gene Presenting With Neonatal Adrenal Insufficiency and Recurrent Intussusception: A Case Report.

Introduction: Primary adrenal insufficiency (PAI) presenting in the neonatal period can be life threatening and requires early recognition, diagnosis, and management. PAI due to adrenal hypoplasia (syndromic/non-syndromic) is a rare disorder. MIRAGE is a recently described syndrome with PAI and multisystem involvement.
