Patterns of follow-up mental health care after hospitalization for suicide-related behaviors among older adults in South Korea.

OBJECTIVE: This study aimed to investigate the sociodemographic and clinical factors associated with receiving follow-up mental healthcare within 7 days and 30 days after hospitalization for suicide-related behaviors (SRB) among older adults in South Korea. METHODS: Data from the Korean National Health Information Database were used, including information on sociodemographic variables and healthcare utilization. The study cohort consisted of individuals born in 1950 or before with a prior hospitalization record for suicide attempts or probable suicide attempts. Logistic regression analysis was conducted to predict the odds of receiving follow-up care within 7 days and 30 days, adjusting for covariates. RESULTS: Among the 37,595 older adults discharged from hospitalization for SRB, 29.13 % and 37.86 % received follow-up care within 7 days and 30 days, respectively. Follow-up care was more common among younger individuals, women, those with higher socio-economic status (SES), urban residents, and individuals with comorbidities. CONCLUSION: The provision of mental health follow-up care for older adults after hospitalization for suicide attempts is inadequate in South Korea. Increasing access to follow-up care among those with lower income, residing in rural areas, and older age is crucial. Public awareness campaigns, stigma reduction training for healthcare providers, and system-level changes, such as telemedicine and integrated care pathways, can help bridge the healthcare gap and reduce suicide mortality among older adults.

Employment conditions and leisure-time physical activity among korean workers: a longitudinal study (2009-2019).

BACKGROUND: Employment conditions may affect individuals' leisure-time physical activity (LTPA). We aimed to examine the relationship between changes in working and employment conditions and LTPA among working-age populations in South Korea from 2009 to 2019. METHODS: A cohort of 6,553 men and 5,124 women aged 19-64 years was analyzed using linear individual-level fixed-effects regressions to examine changes in working and employment conditions with changes in LTPA. RESULTS: Reduced working hours, labor union membership, and part-time work were associated with increased LTPA for both sexes. Manual labor and self-reported precarious work were associated with reduced LTPA. The longitudinal relationship between employment conditions and LTPA was clear in men, but less apparent in women. CONCLUSIONS: Changes in working and employment conditions had longitudinal associations with changes in LTPA among working-age Koreans. Future research should examine changing employment conditions and their effect on LTPA, particularly among women and manual/precarious workers. These results could inform effective planning and interventions to increase LTPA.

Dermoscopic "Landscape Painting Patterns" as a Clue for Labial Melanotic Macules: An Analysis of 80 Cases.

BACKGROUND: Labial melanotic macules (LMMs) are benign pigmented lesions that usually take the shape of flat asymmetrical macules with tan-brown to black color and variable size. Whereas the dermoscopic features of other pigmented skin lesions have been relatively well described, little is known about LMMs. OBJECTIVE: To describe the dermoscopic features and find typical and schematic dermoscopic patterns in LMMs. METHODS: A retrospective dermoscopic study was conducted on 80 lesions with histopathologically proved LMMs. RESULTS: We described and defined, for the first time to our knowledge, landscape painting patterns found in 65 of 80 melanotic lesions (81.3%), characterized by parallel lines or circle lines, overlapping vessels with background brown pigmentation. The background brown pigmentations were observed in 74 of 80 lesions (92.5%), the parallel lines in 62 (77.5%), the circle lines in 20 (25.0%), and overlapping vessels in 69 (86.3%). The structureless black pigmentations were only presented in 26 of 80 (32.5%). CONCLUSION: Dermoscopy can be useful for the clinical detection of LMMs, and "Landscape painting patterns" may represent a dermoscopic clue for the diagnosis of these lesions.

Association between Breslow thickness and dermoscopic findings in acral melanoma.

BACKGROUND: Dermoscopy is a useful tool for the diagnosis of acral melanomas (AMs). However, little is known about the influence of tumor thickness on the dermoscopic findings of AM. OBJECTIVE: To investigate the affect Breslow thickness (BT) has on the dermoscopic patterns of AM. METHODS: Data on cases of AM on the glabrous skin were collected from 4 university hospitals. We investigated the frequency of each dermoscopic feature of AM according to the BT. Statistical analysis was performed to investigate the association between the specific dermoscopic patterns and BT. RESULTS: Multivariable analysis revealed that the colors red (odds ratio [OR] 16.482, 95% confidence interval [CI] 3.605-99.016); blue (OR 7.092; 95% CI 1.707-37.435); and white (OR 5.048, 95% CI 1.152-22.897) were more common in AM with BT >2 mm than those with BT ≤2 mm. Regarding patterns, atypical vascular (OR 34.589, 95% CI 6.458-305.852); blue-white veils (OR 9.605, 95% CI 1.971-72.062); and ulcers (OR 5.084, 95% CI 1.145-24.152) were more frequently detected in cases with BT >2 mm than those with BT ≤2 mm. LIMITATIONS: A retrospective study design and small sample size. CONCLUSION: This study showed an association between dermoscopic patterns and tumor thickness among patients with AM. Dermoscopy can be a useful adjuvant tool for predicting BT in AM.

Outbreak investigation of pertussis in an elementary school: a case-control study among vaccinated students.

PURPOSE: A pertussis patient from an elementary school, in Gyeonggi Province, Korea, was notified to public health authority on July 25, 2017. Epidemiologic investigation was conducted to identify the magnitude, possible source of infection and risk factors for this outbreak on August 17, 2017. MATERIALS AND METHODS: A case was defined as the school student experiencing cough for more than two weeks with or without paroxysmal, whoop, or post-tussive vomiting. Control was defined as the student polymerase chain reaction-negative at the school. School based surveillance was implemented to identify additional cases. RESULTS: From June 29 to August 27, 2017, nine patients of pertussis were identified from an elementary school. Among nine cases, eight were confirmed by polymerase chain reaction positive. All cases had cough, one (11%) had post-tussive vomiting, and one (11%) had fever. Eight cases had macrolide for 7 days in outpatient clinic, and one case admitted in a hospital. There was no significant difference of demographic factors including gender (p=0.49), age group (p=0.97), number of series of vaccination of pertussis (p=0.52), the number of participation of after school activity (p=0.28), and the time elapsed since last vaccination (p=0.42). However, we found the history of contact within the classroom or after-school activity was only the independent risk factor among all the demographic factors collected (odds ratio, 63.61; 95% confidence interval, 4.35 to 930.79). CONCLUSION: The contributing factor for transmission is associated with the case-contact. Immediate identification of pertussis with use of appropriate diagnostic test may help to avoid a large number of cases.

High rates of secondary non-adherence causes decreased efficacy of 0.1% topical tacrolimus in adult eczema patients: results from a multicenter clinical trial.

BACKGROUND: Patients tend to apply topical medications less frequently, in improper amounts. Not only frequency but also application amount may influence treatment outcome. However, studies on relationship between application amount and objective treatment outcome have rarely been conducted. OBJECTIVE: To assess efficacy of topical agent according to application amount in adult patients, using the finger-tip unit method. METHODS: The efficacy of 0.1% topical tacrolimus in adult patients with localised atopic dermatitis was assessed using EASI, TIS, IGA, and PGA scores at baseline, follow-up. Adherence in amount was evaluated after 2 weeks of treatment using the ratio of the actual amount applied to the expected amount applied (A/E). RESULTS: Twenty-seven patients (20.93%) used topical tacrolimus in proper amounts (A/E: 0.8-1.2). However, 86 patients (66.67%) underused topical tacrolimus; 16 (12.40%) patients overused topical tacrolimus. Decreases in EASI scores between baseline and 2 weeks of follow-up in each group (under-amount, proper amount, over-amount) were 1.64, 4.65 and 4.21, respectively. Treatment efficacy increased in accordance with application amount. Further, TIS, IGA, PGA, VAS for Itch and DLQI scores improved concomitantly, exhibiting similar tendencies. CONCLUSION: Application amount of topical agent is important in increasing treatment efficacy in adult patients with atopic dermatitis.

Various Dermatoses What the Patients with Cutaneous Melanoma Had Anxiety for the Recurrence during Postoperative Surveillance.

BACKGROUND: The incidence and mortality rates associated with cutaneous melanoma (CM) have steadily increased over the last 20 years. Even with successful treatment, melanoma patients usually experience substantial anxiety regarding the development of terrible recurrence. To date, few studies have investigated various dermatoses what the patients with CM had anxiety for the recurrence during postoperative surveillance (Dw). OBJECTIVE: To describe various Dw and to evaluate the risk of subsequent malignant skin disease in patients with CM. METHODS: We performed a prospective study between August 2002 and August 2015. RESULTS: Fifty-six patients presented with a total of 68 Dw. Among them, melanocytic nevus was the most common (n=27), followed by seborrheic keratosis (n=9) and CM recurrence (n=7). Approximately 5.6% of the lesions were diagnosed as malignant skin diseases. This was a single-center study, so the prevalence of malignant skin diseases following primary melanoma may not represent that of all patients with CM. CONCLUSION: The results of this study can be referred by dermatologists dealing with melanoma especially when CM patients have too excessive or unrealistic anxiety for melanoma recurrence during postoperative surveillance of CM. However, the importance of postoperative surveillance must still be emphasized because of real risk of melanoma recurrence and other malignant skin.

Arborizing Vessels on Dermoscopy in Various Skin Diseases Other Than Basal Cell Carcinoma.

BACKGROUND: Arborizing vessels (AVs) are dermoscopically defined as telangiectasias with distinct treelike branching, and are a characteristic feature of basal cell carcinoma (BCC). However, AVs are observed in various conditions other than BCC. OBJECTIVE: The aim of this study was to investigate skin diseases showing AV and investigates dermoscopic differences between BCC and non-BCC. METHODS: Dermoscopic images showing AV were prospectively collected and classified into BCC/non-BCC. Non-BCC was further classified into tumors (benign cystic, benign non-cystic, premalignant, and malignant) and non-tumors. We compared AV focusing, widest diameter of stem vessels, widest diameter ratio of stem vessel to first branch, and number of ramifications between groups. RESULTS: Among 124 images, 54.0% were BCC and 46.0% were non-BCC. Non-BCC included epidermal cysts, hypertrophic scars/keloids, intradermal nevi, actinic keratoses, etc. The proportion of focused AV in BCC was significantly higher and the proportion of unfocused AV in BCC was lower than that of premalignant and malignant non-BCC. The widest diameter ratio of stem vessel to first branch was higher in non-BCC. Number of ramifications was significantly less in benign cystic non-BCC than BCC. CONCLUSION: Various skin diseases showed AV, so that diagnoses other than BCC should be considered. The findings in this study could help discriminate BCC from non-BCC.
