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. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: “low libido”, “erectile dysfunction”, “ejaculatory dysfunction”, “premature ejaculation”, “retrograde ejaculation”, “delayed ejaculation”, “anejaculation”, and “orgasmic dysfunction” between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socioeconomic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient’s individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.

Purpose: To investigate the relative risks (RRs) for dementia among individuals with glaucoma. Methods: We conducted a search of PubMed, Web of Science, Scopus, and Cochrane databases for observational cohort studies examining the association between glaucoma and dementia until March 2023. Two authors independently screened all titles and abstracts according to predefined inclusion and exclusion criteria. Pooled RR and 95% confidence intervals (CIs) were generated using random-effect models. Results: The meta-analysis included 18 cohort studies conducted in eight countries and involving 4,975,325 individuals. The pooled RR for the association between glaucoma and all-cause dementia was 1.314 (95% CI, 1.099–1.572; I2 = 95%). The pooled RRs for the associations of open-angle glaucoma with Alzheimer dementia and Parkinson disease were 1.287 (95% CI, 1.007–1.646; I2 = 96%) and 1.233 (95% CI, 0.677–2.243; I2 = 73%), respectively. The pooled RRs for the associations of angle-closure glaucoma with all-cause dementia and Alzheimer dementia were 0.978 (95% CI, 0.750–1.277; I2 = 17%) and 0.838 (95% CI, 0.421–1.669; I2 = 16%), respectively. No evidence of publication bias was detected in the Begg-Mazumdar adjusted rank correlation test (p = 0.47). Conclusions Based on current observational cohort studies, there is evidence supporting that glaucoma is a risk factor for dementia in the adult population.

Purpose: We introduce a “cold steel” hammer-chisel technique for endoscopic dacryocystorhinostomy, then compare postoperative outcomes between this technique and a drill technique. Methods: This study included 191 patients (297 eyes) with nasolacrimal duct stenoses or obstructions who underwent endoscopic dacryocystorhinostomy using the hammer-chisel or drill technique. Surgical outcomes were compared via follow-up screening for epiphora and anatomical complications such as granuloma and fibrous membrane formation, canalicular obstruction, and synechiae. Results: Postoperative anatomical complications occurred in 29 eyes (18.6%) in the hammer-chisel group and 51 eyes (36.2%) in the drill group (p = 0.001). The anatomical failure rate was higher in the drill group [28 eyes (19.9%)] than in the hammer-chisel group [18 eyes (11.5%); p = 0.038]. Functional failure was observed in 13 eyes (8.3%) in the hammer-chisel group and 13 eyes (9.2%) in the drill group (p = 0.787). The mean operation time was significantly longer in the drill group (35.5 ± 10.4 minutes vs. 25.4 ± 9.1 minutes) (p < 0.001). Conclusions During endoscopic dacryocystorhinostomy, osteotomy with a hammer-chisel is more successful and leads to fewer complications than osteotomy with a drill.

Objectives: Recently, weight loss has emerged as a national concern in South Korea, and this has resulted in an increase in the frequency of use of central nervous system (CNS)-stimulating appetite suppressants. This study aimed to collect cases of psychotic disorders and bipolar disorders triggered by phentermine and phendimetrazine and explore the clinical features and courses. Methods: In this retrospective study, we analyzed the electronic medical records of patients and selected eight patients who developed psychotic symptoms and manic symptoms for the first time after taking phentermine and phendimetrazine. All cases were reviewed, and their clinical features and course were summarized. Results: All eight patients developed psychotic symptoms, and one had accompanying manic symptoms. The final diagnosis was appetite-suppressant-induced psychotic disorder in four patients, schizophrenia in three, and appetite-suppressant-induced bipolar disorder in one. In addition, three patients were diagnosed as having substance-use disorder. The key psychotic symptoms of these patients were hallucinations and paranoia. Conclusions These case findings suggest that phentermine and phendimetrazine can cause psychotic disorder, bipolar disorder, or substance use disorder and that medical professionals and the public should practice caution when prescribing and using these drugs.

Purpose: To report a rare case of severe ocular hypertension following intravenous methylprednisolone treatment in a child with bilateral optic neuritis.Case summary: A 6-year-old girl presented with bilateral severe visual loss and disc swelling. Magnetic resonance imaging revealed optic nerve enhancement, and she received high-dose intravenous methylprednisolone for 3 days and oral prednisolone 30 mg/day for 2 weeks. Two weeks after initiating treatment, ophthalmologic examination revealed an intraocular pressure (IOP) of 46 mmHg in the right eye and 42 mmHg in the left eye. The best-corrected visual acuity was 1.0 in the right eye and 0.6 in the left eye. Relative afferent pupillary defect was noted in the left eye. Fundus examination showed normal cup-to-disc ratio (0.4) in both eyes. The iridocorneal angle was open in all directions. The treatment plan included the cessation of oral prednisolone and initiation of latanoprost and dorzolamide-timolol fixed combination agent. After 12 hours, the IOP decreased to 18 mmHg in the right eye and 14 mmHg in the left eye. Six months later, her visual acuity was 1.0 in both eyes, and IOP was maintained at 11 and 13 mmHg in the right and left eye, respectively. Optic disc examination showed no sign of glaucomatous change with normal cup-to disc ratio in both eyes. Conclusions Since steroid medication may cause asymptomatic IOP elevation, regular intraocular pressure measurements are required during steroid treatment for pediatric optic neuritis. The administration of IOP-lowering eyedrops returned IOP to the normal range without damaging the optic nerve.

Hepatocellular carcinoma (HCC) primarily originates in the liver with hepatic differentiation. However, HCCs are not homogenous, and approximately 35% of HCC cases are classified as histopathological variants that present distinct pathologic characteristics. In particular, the lymphocyte-rich variant is the rarest subtype accounting for less than 1% of HCCs, which is not well known to date about molecular features and pathophysiology. Herein, we present a case of a patient who was suspected of metastatic liver cancer and confirmed as lymphocyte-rich HCC pathologically. A 78-year-old woman who underwent a right hemicolectomy for colon cancer was referred to our hospital for a newly detected liver mass. We could not make a decision because of insufficient evidence for diagnosis from imaging studies. After resection, we found that it was a lymphocyte-rich HCC. The pathologic features and prognostic trends of this subtype are also discussed.

Purpose: To investigate changes in intraocular pressure (IOP) and iridocorneal angle (ICA) configuration during smartphone use under room light. Methods: We included healthy adults aged 19-35 years with no ophthalmological abnormalities. All read text on a smartphone for 6 minutes under room light. IOP was measured via rebound tonometry at baseline and at 2, 4, and 6 minutes. ICA images were obtained via anterior segment optical coherence tomography after each IOP measurement. After 6 minutes, participants stopped reading text and rested for 2 minutes. IOP was then measured again. Results: The IOP significantly increased at 2, 4, and 6 minutes of reading compared to baseline (p < 0.001) but recovered to baseline after 2 minutes of rest (p = 1.000). The anterior chamber depth decreased significantly, and the anterior chamber angle width increased after 6 minutes of smartphone reading (both p < 0.05). Conclusions IOP increased when reading smartphone text under room light but the ICA did not change. Prolonged smartphone reading is inappropriate for a patient at risk of glaucoma or glaucoma progression. Such patients should be cautioned.

Background: Despite the wide demand for thin flaps for various types of extremity reconstruction, the thin elevation technique for anterolateral thigh (ALT) flaps is not very popular because of its technical difficulty and safety concerns. This study proposes a novel perforatorcentralizing technique for super-thin ALT flaps and analyzes its effects in comparison with a skewed-perforator group. Methods: From June 2018 to January 2020, 41 patients who required coverage of various types of defects with a single perforator-based super-thin ALT free flap were enrolled. The incidence of partial necrosis and proportion of the necrotic area were analyzed on postoperative day 20 according to the location of superficial penetrating perforators along the flap. The centralized-perforator group was defined as having a perforator anchored to the middle third of the x- and y-axes of the flap, while the skewed-perforator group was defined as having a perforator anchored outside of the middle third of the x- and y-axes of the flap. Results: No statistically significant difference in flap thickness and dimension was found between the two groups. The arterial and venous anastomosis patterns of patients in both groups were not significantly different. Only the mean partial necrotic area showed a statistically significant difference between the two groups (centralized-perforator group, 3.4%±2.2%; skewed-perforator group, 15.8%±8.6%; P=0.022). Conclusions The present study demonstrated that super-thin ALT perforator flaps can be elevated safely, with minimal partial necrosis, using the perforator-centralizing technique.
