Background: In alopecia totalis (AT) and alopecia universalis (AU), the chance of full hair regrowth is known to be less than 10%. However, this information is based on a few older studies conducted in the 1950s and 1960s.Objective: We investigated the current long-term prognosis of individuals with AT/AU.Methods: A retrospective chart review was performed in patients with AT/AU between 1994 and 2005. Outcome data were collected by reviewing outpatient clinical files or by phone interviews. Finally, the long-term assessment of 70 patients with valid outcome data was performed.Results: Twelve out of 70 patients with AT/AU (17.1%) had complete hair regrowth. Five out of 24 patients with AT (20.8%) showed complete hair regrowth, and 7 of 46 patients with AU (15.2%) achieved complete regrowth. Seventeen out of 70 patients with AT/AU (24.2%) reported hair regrowth greater than or equal to 90%. Thirty patients with AU (65.2%) remained in an alopecic state without improvement, while 5 patients with AT (20.8%) showed no hair regrowth.Conclusion: Our results suggest that the long-term prognosis of AT/AU is more favorable than previously thought. However, the clinical burden of AT/AU is still substantial. [ABSTRACT FROM AUTHOR]

Background: Transcatheter arterial embolization (TAE) has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management, but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage (PPH)., Aim: To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings., Methods: We conducted a research from January 2008 to July 2022 on all 83 patients (mean: 32 years, range: 24-43 years) presented with secondary PPH and they were treated with TAE in two university hospitals. The medical records and angiography were retrospective reviewed in order to evaluate the patients' characteristics, delivery details, clinical status and peri-embolization management, angiography and embolization details, technical/clinical success and complications. The group with active bleeding sign and the group without it were also compared and analyzed., Results: On angiography, 46 (55.4%) patients showed active bleeding signs such as contrast extravasation ( n = 37) or pseudoaneurysm ( n = 8) or both ( n = 1), and 37 (44.6%) patients showed non-active bleeding signs such as only spastic uterine artery ( n = 2) or hyperemia ( n = 35). In the active bleeding sign group there were more multiparous patients, low platelet count, prothrombin time prolongation, and high transfusion requirements. The technical success rates were 97.8% (45/46) in active bleeding sign group and 91.9% (34/37) in non-active bleeding sign group, and the overall clinical success rates were 95.7% (44/46) and 97.3% (36/37). An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization, therefore hysterostomy and retained placenta removal were performed which was a major complication., Conclusion: TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings., Competing Interests: Conflict-of-interest statement: All the authors declare no conflicts of interest., (©The Author(s) 2023.

Objectives: This study evaluated the response in Daegu, Korea to the first wave of the coronavirus disease 2019 (COVID-19) pandemic according to a public health emergency response model., Methods: After an examination of the official data reported by the city of Daegu and the Korea Centers for Disease Control and Prevention, as well as a literature review and advisory meetings, we chose a response model. Daegu's responses were organized into 4 phases and evaluated by applying the response model., Results: In phase 1, efforts were made to block further transmission of the virus through preemptive testing of a religious group. In phase 2, efforts were concentrated on responding to mass infections in high-risk facilities. Phase 3 involved a transition from a high-intensity social distancing campaign to a citizen participation-based quarantine system. The evaluation using the response model revealed insufficient systematic preparation for a medical surge. In addition, an incorporated health-related management system and protection measures for responders were absent. Nevertheless, the city encouraged the participation of private hospitals and developed a severity classification system. Citizens also played active roles in the pandemic response by practicing social distancing., Conclusions: This study employed the response model to evaluate the early response in Daegu to the COVID-19 pandemic and revealed areas in need of improvement or maintenance. Based on the study results, creation of a systematic model is necessary to prepare for and respond to future public health emergencies like the COVID-19 pandemic.

Background: Although particulate matter likely provokes inflammatory reactions in those with chronic skin disorders like atopic dermatitis, no study has examined the relationship between particulate matter and psoriasis exacerbation., Objective: This study evaluated possible associations between particulate matter and hospital visits for psoriasis patients in 7 major cities in South Korea., Methods: We investigated the relationship between psoriasis and particulate matter. To do this, we used psoriasis patient data from the Korean National Health Insurance Service database. In addition, PM 10 and PM 2.5 concentration data spanning a 3-year time frame were obtained from the Korea Environment Corporation., Results: A pattern analysis generated by the sample cross-correlation function and time series regression showed a correlation between particulate matter concentration and the number of hospital visits by psoriasis patients. However, the prewhitening method, which minimizes the effects of other variables besides particulate matter, revealed no correlation between the two., Conclusion: This study suggests that particulate matter has no impact on hospital visit frequency among psoriasis patients in South Korean urban areas., Competing Interests: CONFLICTS OF INTEREST: The authors have nothing to disclose., (Copyright © The Korean Dermatological Association and The Korean Society for Investigative Dermatology.)

Objectives: The objective of the present study was to compare prognosis of patients with gastric or colorectal cancer according to places where they received surgeries., Methods: The cancer patients underwent surgeries in sampled hospitals located in Daegu were matched 1:1 to the patients who visited sampled hospitals in Seoul using propensity score method. After the occurrences of death were examined, Kaplan-Meier method was used for survival analysis and the log-rank test was performed to compare the survival curves., Results: A total of six out of 291 gastric cancer patients who had surgeries in Daegu died (2.1%) and ten deaths (3.4%) occurred from patients went Seoul hospitals. Out of 84 gastric cancer patients who had chemotherapy after surgeries in Daegu, 13 (15.5%) patients died while 18 (21.4%) deaths occurred among patients underwent surgeries in Seoul. Six deaths (6.9%) out of 87 colorectal cancer patients who had surgeries in Daegu were reported. Five patients (5.7%) died among the patients underwent surgeries in Seoul. Among the colorectal cancer patients with chemotherapy after surgeries, 13 patients (12.4%) who visited hospitals in Daegu and 14 (13.3%) patients who used medical centers in Seoul died. There were no significant differences according to places where patients used medical services., Conclusions: The result of this study is expected to be used as basic data for policy making to resolve centralization problem of cancer patients and to help patients to make rational choices in selection of medical centers.

Purpose: We assessed medication nonadherence, categorized as intentional or unintentional, and related factors in elderly patients with hypertension, correlating the data with measurement of blood pressure as the final target of medication adherence and other possible influencing factors, such as lifestyle., Patients and Methods: Subjects were aged ≥65 years, resided in a rural area, and were taking antihypertensive drugs. The survey was conducted in July 2014. Participants were divided into the following three groups: "Adherence", "Unintentional nonadherence", and "Intentional nonadherence". Individual cognitive components, such as necessity and concern as well as self-efficacy and other related factors, were compared according to adherence groups. The interrelationships between those factors and nonadherence were tested using structural equation modeling analysis., Results: Of the 401 subjects, 182 (45.6%) were in the adherence group, 107 (26.7%) in the unintentional nonadherence group, and 112 (27.9%) in the intentional nonadherence group. Necessity and self-efficacy were found to have a significant direct influence on unintentional nonadherence behaviors (necessity β=-0.171, P =0.019; self-efficacy β=-0.433, P <0.001); concern was not statistically significant (β=-0.009, P =0.909). Necessity was found to have significant direct and indirect impact on intentional nonadherence (direct β=-0.275, P =0.002; indirect β=-0.113, P =0.036). Self-efficacy had no significant direct effect on intentional nonadherence though it had the only significant indirect effect on intentional nonadherence (direct β=-0.055, P =0.515; indirect β=-0.286, P <0.001). Concern had no significant influence on intentional or on unintentional nonadherence (direct β=0.132 0.132, P =0.151; indirect β=-0.006, P =0.909)., Conclusion: Unintentional nonadherence should be regularly monitored and managed because of its potential prognostic significance. Interventions addressing cognitive factors, such as beliefs about medicine or self-efficacy, are relatively difficult to implement, but are essential to improve medication adherence.

Purpose: This study aimed to examine the following questions: to what extent do patients and caregivers perceive their family members to be avoidant of communication regarding patient's cancer, and to what extent do these perceptions interrelate; and how do such perceptions influence their own and each other's communication behaviors, communication outcome, mental health, and quality of life., Materials and Methods: A national survey was performed with 990 patient-caregiver dyads (participation rate, 76.2%). To examine the dyadic interaction, we developed linked patient and family member questionnaires, including the Family Avoidance of Communication about Cancer (FACC) scale., Results: The mean scores (standard deviations) of patient- and caregiver-perceived FACC were low at 10.9 (15.5) and 15.5 (17.5), respectively (p < 0.001), and concordance was low, a well (Spearman's rho, 0.23). Patient-perceived FACC was associated with lower levels of disclosure and behaviors of holding back communication, as well as lower levels of mental health outcome and quality of life. The same was true for caregivers (all p < 0.05). Patient-perceived FACC was associated with caregiver holding back, caregiver's depression level, and caregiver quality of life (all p < 0.05). Both patient- and caregiver-perceived FACC were independently associated with communication difficulty within the family., Conclusion: Future research would benefit from the measurement of FACC from both patients and caregivers, and promote family intervention to enhance openness to communication, which would be helpful for improving mental health and quality of life for both patients and caregivers.

Background: Despite the consistent relationship between serum γ-glutamyltransferase (GGT) and type 2 diabetes (T2D), one unsolved issue is the role of serum GGT in the well-known association between obesity and T2D. This study was performed to investigate whether the association between body mass index (BMI) and impaired fasting glucose (IFG) differed depending on serum GGT levels within the normal range., Methods: Study subjects were 2,424 men and 3,652 women aged ≥ 40, participating in the Fifth Korean National Health and Nutrition Examination Survey. Serum GGT levels within the normal range were classified into gender-specific tertiles., Results: Among men and women belonging to the lowest tertile of serum GGT, BMI showed statistically non-significant weak associations with the risk of IFG. However, among persons in the highest tertile of serum GGT, the risk of IFG was 3 - 4 times higher among persons with BMI ≥ 25 kg/m2 than those with BMI < 23 kg/m2 (Pinteraction = 0.032 in men and 0.059 in women)., Conclusions: The well-known strong association between BMI and IFG was observed mainly among persons with elevation of serum GGT to certain physiological levels, suggesting a critical role of serum GGT in the pathogenesis of IFG. This finding has an important clinical implication because serum GGT can be used to detect high-risk obese persons.

Public health centers in Korea play an important role at the community level in encouraging residents to participate in cancer screening, usually by sending reminders in the mail and by making phone calls. However, there have not been any studies on the effectiveness of these interventions by public health centers in Korea. The purpose of this study was to evaluate this question. The study was limited to male subjects aged 50-59 years living in one district of Daegu, Korea. A total of 923 subjects were selected for the study among the target population for gastric and colorectal cancer screening as part of the National Cancer Screening Program in 2012. The subjects were randomly assigned to one of four groups: control, postal intervention, telephone intervention, and telephone and postal intervention. Three months after the interventions, the results were confirmed by the National Health Insurance Corporation. Logistic regression analyses were performed to find differences in participation rates in cancer screening for each group. Men who received telephone and postal intervention were most likely (40.5%) to undergo gastric cancer screening, in comparison to the men who received telephone intervention only (31.7%), postal intervention only (22.2%) and those in the control group (17.9%). Also, men who received telephone and postal intervention were most likely (27.8%) to participate in colorectal cancer screening, followed by the men who received telephone intervention only (24.3%), postal intervention only (16.5%), and men in the control group (13.5%). Combined telephone and postal intervention and telephone only intervention as well produced significantly increased rates of participation in cancer screening in comparison to the control group. There was no significant difference, however, between the postal intervention only and control groups for either colorectal or gastric cancer screening.

Objectives: Cigarette smoking prevalence among adolescent males in rural areas of Korea has increased in recent years. The aim of this study was to explore the factors related to increasing trends in cigarette smoking among adolescent males living in rural areas., Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey from 2006 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Multiple logistic regression models were used to explore the factors affecting cigarette smoking. We evaluated the linear time trends in the prevalence of factors that were related to current smoking status and the linear time trends in cigarette smoking in groups stratified by the exposure to each factor using logistic regression models. Finally, we examined the contributions of the factors to the time trends in cigarette smoking by adjusting for each of those factors in the baseline regression models and changes in the adjusted odds ratio by survey year., Results: A statistically significant increasing trend in smoking was observed after adjusting for the factors affecting cigarette smoking. Significant factors related to cigarette use were perceived stress, experience with depression, current alcohol drinking, exposure to secondhand smoke, and academic performance. The factor related to increasing trends in cigarette smoking was academic performance., Conclusions: Stress about academic performance is an important factor affecting the increase in cigarette smoking among adolescent males in a rural area of Korea.

Objectives: Even though experimental studies have suggested that iron can be involved in generating oxidative stress, epidemiologic studies on the association of markers of body iron stores with cardiovascular disease or cancer remain controversial. This study was performed to examine the association of serum ferritin and transferrin saturation (%TS) with all-cause, cancer, and cardiovascular mortality., Methods: The study subjects were men aged 50 years or older and postmenopausal women of the Third National Health and Nutrition Examination Survey 1988-1994. Participants were followed-up for mortality through December 31, 2006., Results: Serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality for either men or postmenopausal women. However, all-cause, cancer, and cardiovascular mortality were inversely associated with %TS in men. Compared with men in the lowest quintile, adjusted hazard ratios for all-cause, cancer, and cardiovascular mortality were 0.85, 0.86, 0.76, and 0.74 (p for trend < 0.01), 0.82, 0.73, 0.75, and 0.63 (p for trend < 0.01), and 0.86, 0.81, 0.72, and 0.76 (p for trend < 0.01), respectively. For postmenopausal women, inverse associations were also observed for all-cause and cardiovascular mortality, but cancer mortality showed the significantly lower mortality only in the 2nd quintile of %TS compared with that of the 1st quintile., Conclusions: Unlike speculation on the role of iron from experimental studies, %TS was inversely associated with all-cause, cancer and cardiovascular mortality in men and postmenopausal women. On the other hand, serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality.

Objectives: Understanding recent trends in cigarette smoking among adolescents is important in order to develop strategies to prevent cigarette smoking. The aim of this study was to compare recent trends in cigarette smoking for adolescents living in rural areas, small towns and metropolitan cities in Korea., Methods: The raw data from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) from 2005 to 2009 were used. Data were analyzed by using the method of complex survey data analysis considering complex sampling design. Logistic regression models were used to evaluate significant linear time trends in cigarette smoking. The indicators of cigarette use behaviors were 'current smoking rate', 'frequent smoking rate', 'heavy smoking rate' and 'smoking experience rate before 13 years of age'. All analyses were conducted according to gender., Results: Statistically significant increasing trends in current smoking rate and frequent smoking rate were observed and borderline significant increasing trends in heavy smoking rate were shown among rural boys. Among metropolitan city boys, statistically significant increasing trends were also seen for frequent smoking. Statistically significant decreasing trends in current smoking rate were observed among small town and metropolitan city girls. Smoking experience rate before 13 years of age for rural girls decreased significantly., Conclusions: Cigarette smoking prevalence among adolescents in the rural areas has increased in the last five years especially among boys. Our findings suggest that anti-tobacco program for adolescents should be conducted primarily for those in rural areas.
