Purpose: We aimed to investigate the prevalence and genotype distribution of human papillomavirus (HPV) among Korean males and explore implications for targeted vaccination strategies. Materials and Methods: A total of 44,065 males underwent HPV testing between March 2014 and February 2022 using the Anyplex™ II HPV 28 system, detecting 19 high-risk (HR) and 9 low-risk (LR) HPV types. Additionally, data from 507 male patients at local clinic (2017–2022) were analyzed to compare genotype prevalence between those with (WAT group) and without (WAT X group) genital warts. Results: Overall HPV positivity was 59.1%. HPV 6 (33.3%) and HPV 11 (11.0%) were the most prevalent LR genotypes, while HPV 16 (5.2%) dominated HR infection. Multiple HPV genotype co-infection occurred in 49.3% of positive cases, with 11.3% involving multiple HR types. Younger males (teens, 20s) exhibited higher HR-HPV positivity, although total HPV positivity peaked in the 40s (60.1%). Non–9-valent HR genotypes (HPV 53, 51, 39, 66) accounted for 27.6%–35.0% of infections annually. At local clinic, HPV 43 was significantly associated with genital warts (p=0.017). Conclusions These data support including males in national HPV vaccination strategies using the current 9-valent vaccine and underscore the need for ongoing genotype surveillance to monitor non‑vaccine high‑risk types and inform public health policy, and support inclusion of males in national HPV vaccination strategies using the current 9‑valent vaccine.

Purpose: To compare the perioperative and postoperative outcomes between traditional trans-vesical robot-assisted simple prostatectomy (TV-RASP) and the newly introduced urethral-sparing (US) RASP. Materials and Methods: We retrospectively reviewed 42 patients who underwent TV-RASP (n=22) or US-RASP (n=20) performed by two experienced surgeons at two tertiary centers. Perioperative outcomes including operation time, estimated blood loss, length of hospital stay, and catheterization time were assessed. Postoperative outcomes were evaluated using the International Prostate Symptom Score (IPSS), quality of life (QoL), uroflowmetry parameters, Male Sexual Health Questionnaire-Ejaculation Dysfunction-Short Form (MSHQ-EjD-SF) scores, and maintenance of anterograde ejaculation. Results: This study analyzed 22 and 20 patients who underwent TV-RASP and US-RASP, respectively. Except for the TV-RASP group being older (70.0 years) than the US-RASP group (64.5 years) (p=0.028), no differences among other baseline characteristics existed. Perioperative outcomes indicated that hospital stay and catheterization time were significantly shorter in the US-RASP group than in the TV-RASP group (p<0.001). At postoperative month 1, the median IPSS and QoL scores were significantly better in the US-RASP group than in the TV-RASP group (p=0.001 and p=0.002, respectively). However, at months 6 and 12, no significant differences were noted in IPSS, QoL, maximum flow rate, and postvoid residual urine between the two groups. Sexually active patients in the US-RASP group maintained postoperative MSHQ-EjD functional and bother scores, whereas the TV-RASP group experienced a decline. Notably, 75.0% of patients in the US-RASP group preserved antegrade ejaculation, compared to only 20.0% in the TV-RASP group (p<0.001). Conclusions US-RASP is not inferior to TV-RASP in terms of functional outcomes. In addition, US-RASP yielded more rapid symptom improvements and preserved antegrade ejaculation than TV-RASP. However, larger prospective studies are required to confirm these findings and to further investigate the long-term efficacy and safety of US-RASP.

PURPOSE: This study aimed to evaluate the effect of pretreatment of three different universal adhesives (Single Bond Universal [SBU], All-Bond Universal [ABU], and Prime&Bond universal [PBU]) on the bonding durability of an adhesive (Panavia F 2.0, PF) and a conventional (Duo-Link, DL) resin cements to air-abraded zirconia. MATERIALS AND METHODS: Rectangular-shaped zirconia specimens were prepared. The chemical composition and surface energy parameters of the materials were studied by Fourier transform infrared spectroscopy and contact angle measurement, respectively. To evaluate resin bonding to the zirconia, all the bonding specimens were immersed in water for 24 h and the specimens to be aged were additionally thermocycled 10000 times before the shear bond strength (SBS) test. RESULTS: The materials showed different surface energy parameters, including the degree of hydrophilicity/hydrophobicity. While the DL/CON (no pretreatment) showed the lowest SBS and a significant decrease in the value after thermocycling (P < .001), the PF/CON obtained a higher SBS value than the DL/CON (P < .001) and no decrease even after thermocycling (P = .839). When the universal adhesives were used with DL, their SBS values were higher than the CON (P < .05), but the trend was adhesive-specific. In conjunction with PF, the PF/SBU produced the highest SBS followed by the PF/ABU (P = .002), showing no significant decrease after thermocycling (P > .05). The initial SBS of the PF/PBU was similar to the PF/CON (P = .999), but the value decreased after thermocycling (P < .001). CONCLUSION The universal adhesive pretreatment did not necessarily show a synergistic effect on the bonding performance of an adhesive resin cement, whereas the pretreatment was beneficial to bond strength and durability of a conventional resin cement.

Snapping triceps syndrome is a rare disease in which the distal portion of the medial triceps dislocates over the medial epicondyle during flexion of the elbow. It is usually accompanied with ulnar nerve dislocation and double snapping is clinically important feature. Dynamic ultrasonography is useful diagnostic tool for snapping triceps syndrome and ulnar nerve dislocation. But it is often misdiagnosed as ulnar nerve dislocation alone. This review reports a case of 28-year-old professional golfer who had a single snapping on elbow, misdiagnosed as ulnar nerve dislocation alone and eventually diagnosed as ulnar nerve dislocation and snapping triceps syndrome and also reflects factors that are overlooked through first and second operations.

Purpose: To evaluated the efficacy and safety of gelatinized Maca (Lepidium meyenii) for eugonadal patients with late onset hypogonadism symptoms (LOH). Materials and Methods: Participants were instructed to receive 1,000 mg of Maca or placebo, two pills at a time, three times per day for 12 weeks before food intake. To evaluate the efficacy of the drug, Aging Males’ Symptoms scale (AMS), Androgen Deficiency in the Aging Males (ADAM), International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF) questionnaires, serologic tests (total testosterone and free testosterone, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol, triglyceride), body weight, and waist circumference were assessed at 4 and 12 weeks after treatment. Results: A total of 80 participants were enrolled and randomly assigned to Maca treated group (n=41) or the placebo group (n=39). AMS, IIEF, and IPSS were significantly (p<0.05) improved in Maca treated group than in the placebo group. ADAM positive rate was also significantly (p<0.0001) decreased in Maca treated group. Conclusions Maca may be considered an effective and safe treatment for eugonadal patients with late onset hypogonadism symptoms.

Purpose: This study investigated metabolic health status as a risk factor for female bladder cancer using the National Health Checkups databases of Korea. Materials and Methods: We defined obesity if body mass index was ≥25 kg/m2 and normal weight as <25 kg/m2. Metabolic unhealthiness was defined when 3 or more criteria of metabolic syndrome were met. A total of 11,461,618 women who took National health Checkups between 2009 and 2012 were categorized as metabolic healthy normal weight (MHNW), metabolic unhealthy normal weight (MuHNW), metabolic health obese (MHO), and metabolic unhealthy obese (MuHO). Multivariable-adjusted Cox regression was done to analyze the hazard ratio of bladder cancer. Results: The mean age was 48±11.55 years and body mass index was 23.19±2.13 kg/m2. During 5.4±1.1 years of follow-up, 3,893 patients were newly diagnosed with bladder cancer. Compared to MHNW group, the hazard ratio of MuHNW group and MuHO group were 1.237 and 1.288, respectively, while 0.997 in the MHO group. As the number of metabolic unhealthy criteria increased, the cumulative incidence of bladder cancer increased. Conclusions As a result of a large-scale study conducted on the female population in Korea, the risk of bladder cancer increased with metabolic unhealthiness. Even with normal weight, if metabolically unhealthy, the risk of bladder cancer increased. The greater the degree of metabolic unhealthiness, the higher the risk of bladder cancer. Education on metabolic healthiness concerning female bladder cancer is necessary.
