Background: Acne vulgaris commonly affects both the face and trunk, yet truncal acne remains underrecognized and less studied in adolescents. Objective: This study aimed to assess the prevalence, perceived severity, stress levels, treatment behaviors, and willingness to seek care in adolescents based on acne location. Methods: A cross-sectional survey was conducted among 211 first-year high school students (104 males, 107 females) in Incheon, South Korea. A structured questionnaire captured data on acne location, severity, stress, treatment history, and willingness to seek care. Analyses included descriptive statistics, χ2 tests, t-tests, and Spearman correlation. Results: Facial acne was reported by 86.7% of participants and truncal acne by 47.4%. The presence of facial and truncal acne was significantly associated (p<0.05), with truncal acne developing approximately one year after facial acne onset (p<0.05). While the mean subjective severity scores for facial (1.61±0.63) and truncal acne (1.57±0.79) were similar (p>0.05), stress levels were significantly higher for facial acne (p<0.05). Treatment rates were substantially lower for truncal acne (17.6%) compared to facial acne (48.6%), despite comparable willingness to seek clinical care. Conclusion Truncal acne is common but undertreated in adolescents. Despite comparable willingness to seek care, actual treatment rates remain low, underscoring a critical gap in management. Given the significant co-occurrence and risk of sequelae, clinicians should routinely assess for truncal acne in adolescents with facial acne and adopt a holistic management strategy addressing both areas.

Verrucous carcinoma of the larynx is a rare, well-differentiated variant of squamous cell carcinoma that is locally invasive but rarely metastasizes. However, diagnosis can be difficult because superficial biopsies often fail to demonstrate the characteristic pushing border of verrucous carcinoma. Consequently, multiple biopsies may fail to establish a definitive diagnosis. Surgical excision remains the primary treatment. We present a case of a 54-year-old man who required several years to achieve a definitive diagnosis of verrucous carcinoma and whose lesion recurred repeatedly despite multiple excisions. This case emphasizes the importance of obtaining adequately deep and wide biopsy specimens for the accurate diagnosis of verrucous carcinoma. It also illustrates the therapeutic dilemma in the management of glottic verrucous carcinoma, as aggressive excision may compromise vocal function, whereas conservative excision increases the risk of recurrence.

Objectives: This study is a retrospective chart review of outpatients who were prescribed prolonged-release melatonin at a university hospital in Korea between January 5, 2015, and January 20, 2020. Methods: Descriptive statistics were conducted for all prescription cases as well as by primary diagnosis. Differences according to sex, age, and final clinical improvement were also examined. In addition, separate analyses were performed for cases where prolonged-release melatonin was prescribed as monotherapy. Results: A total of 1,764 cases were analyzed. Prescriptions were more common in females, with a mean age of 66.24 years.The most frequent primary diagnosis was insomnia. At the initial visit, symptom severity ranged from mild to moderate, and at the final visit, patients were generally minimally improved. A total of 866 cases involved prolonged-release melatonin prescribed as monotherapy, with a higher proportion of male patients. The initial symptom severity in these cases was milder than that of the overall prescription cases. Conclusion These findings suggest the practical clinical utility of prolonged-release melatonin.

A single exposure to stress can induce functional changes in neurons, potentially leading to acute stress disorder or post-traumatic stress disorder.In this study, we used in vivo wide-field optical mapping to simultaneously measure neural calcium signals and hemodynamic responses over the whole cortical area. We found that cortical mapping to whisker stimuli was altered under acute stress conditions. In particular, callosal projections in the anterior cortex (primary/secondary motor, somatosensory forelimb cortex) relative to barrel field (S1BF) of somatosensory cortex were weakened. On the contrary, the projections in posterior cortex relative to S1BF were mostly unchanged or were only occasionally strengthened. In addition, changes in intra-cortical connection were opposite to those in inter-cortical connection. Thus, the S1BF connections to the anterior cortex were strengthened while those to the posterior cortex were weakened. This suggests that the well-known barrel cortex projection route was enhanced. In summary, our in vivo wide-field optical mapping study indicates that a single acute stress can impact whole-brain networks, affecting both neural and hemodynamic responses.

Objectives: This study analyzed the current state of community mental health programs in Korea to develop evidence-based criteria for these programs. Methods: Seventy community mental health facilities nationwide were surveyed about the scope of their operated mental health programs. Details, including program structure, staff expertise, standardization, and quality management, of the 511 programs submitted by the facilities as their representative programs were also analyzed to evaluate their efforts for evidence-based practice. Results: The average number of programs operated by community mental health welfare centers was 15.9. The most common programs were those related to serious mental illness (SMI), followed by child/adolescent mental health programs, early psychosis programs, and non-SMI adult mental health programs. In the case of community addiction management centers, there were 7.2 different addiction-related programs per center. Among the psychiatric rehabilitation facilities for SMI, the average number of programs for SMI was 13.1, with some programs for early psychosis. Of the 511 programs submitted as representative programs in their facilities, only 12.3% were judged to be good evidence-based programs. Conclusion More efforts by mental health professionals and governments are needed to implement evidence-based programs in Korea.

Objective: This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia. Methods: Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed. Results: Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35–4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea. Conclusion Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.

Background: Pain assessment and patient education are essential for successful postoperative pain management. However, the provision of personnel for performing these tasks is often insufficient. Recently, attempts have been made to implement smartphone applications for educating and monitoring surgical patients. We developed a smartphone application (app) for postoperative pain management, and conducted a feasibility study. Methods: This single-center prospective observational study included 60 patients aged < 70 years who underwent elective surgery. This study evaluated the SmartAPS application, which offers tools for postoperative pain assessment and educational materials for pain management. The primary outcome was the active usage rate, defined as responding at least twice daily on postoperative days (PODs) 1 and 2. Additionally, we investigated patient satisfaction with the app and educational videos as well as any challenges encountered during use. Results: Sixty patients were enrolled in the study and active app use was achieved in 56.7% of them. Response rates peaked at 85.0% for pain intensity and 83.3% for opioid-related side effects at 14:00 on POD 1 but dropped to 56.7% and 58.3%, respectively, at 18:00 on POD 2. Among the patients who responded to the survey regarding the app usage, 84.0% reported satisfaction with the app and 80% found it beneficial for managing postoperative pain. Furthermore, 92.0% did not encounter difficulties using the app, indicating a generally positive user experience. Conclusions Our findings support the utility of the SmartAPS application in acute pain services, highlighting its potential for improving postoperative pain management.
