Background: Our study aimed to investigate the mediating role of work–family conflict (WFC) on the relationship between long commutes and workers' anxiety and insomnia. Methods: Our study measured the two dimensions of WFC, time-related, and strain-related, which were considered multiple mediators. The mediating effect of WFC on anxiety and insomnia was investigated by decomposing the total effect into a direct effect (long commuting time → anxiety or insomnia) and an indirect effect (long commuting time → WFC → anxiety or insomnia). The combined indirect effect (joint indirect effect) of strain-related WFC and time-related WFC was estimated. The effects were presented as odds ratios and 95% confidence intervals (CIs). Results: The direct effect of 120 min or longer of commuting time was 1.39 (95% CI: 1.17–1.65) times increase in the odds of anxiety and 1.64 (95% CI: 1.41–1.90) times increase in the odds of insomnia than those whose commuting time was less than 60 min. In the case of indirect effects, those whose commuting time was 120 min or longer had 1.13 times higher odds of anxiety (95% CI: 1.07–1.18) and 1.12 times higher odds of insomnia (95% CI: 1.07–1.17) via WFC. The joint indirect effects accounted for 26.4% and 18.5% of the total effect on anxiety and insomnia, respectively. The longer the commuting time, the stronger both direct and indirect effects. Conclusions Our findings highlight the mediating effect of WFC on the relationship between long commuting times and workers' anxiety and insomnia.

A 16-year-old girl was transferred to the department of thoracic and cardiovascular surgery because of a spontaneous pneumothorax with prolonged air leakage. Chest computed tomography demonstrated a cystic lesion measuring 2×3 cm and involving the left upper lobe. Left upper lobectomy was performed via video-assisted thoracoscopic surgery. A pathologic examination of the specimen revealed a mesenchymal cystic hamartoma. Despite the rarity of pulmonary mesenchymal cystic hamartoma, it should be considered a potential cause of pneumothorax for patients with a large pulmonary cyst. Further, surgical resection must be considered because serious complications such as hemothorax, hemoptysis, and malignant transformation have been reported.

Abdominal desmoid tumor is a very rare neoplasm and arises from musculoaponeurotic structures. Approximately 80% of cases occur in woman, usually between the ages of 20 and 40 years, but they have been described in both men and women of all ages. Typically, abdominal desmoid tumor occurs most commonly in the rectus abdominis muscle and in young, gravid, or parous women during gestation or, more frequently, during first year following childbirth. The rates of recurrence following local excision of desmoid tumors have been reported to be about 24%, but metastases do not occur. We experienced one case of desmoid tumor of the rectus abdominis muscle in a 28-year old woman with pregnancy and so present it with brief review of literatures.

The infantile polycystic kidney disease is rare urinary tract anomaly.It is inherited with an autosomal recessive pattern and recurrence rate is about 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic findings of infantile polycystic kidney are oligohydroamnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia will be developed. If it is diagnosed before viability, termination of pregnancy would be recommended. In a fetus diagnosed after viability, pregnancy termmination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

Cellular schwannoma is a very rare benign tumor involving peripheral nerves, mimicking malignant nerve sheath tumor in histological appearance. It is a clinico-pathological variant of benign schwannoma characterized by a high cellularity, increased mitotic figures and occasional presence of bone destruction. A 6-month-old female patient was admitted with progressive quadriparesis. Magnetic resonance imaging of the cervical spine showed a well-enhancing extramedullary mass on the C4 to C6 area. Total laminectomy was performed on C4-7, and intradural extramedullary tumor was removed. Histologically, the tumor was composed of proliferated spindle cells. Most of the tumor was composed of Antoni A area with hypercellular spindle cells arranged in fascicular pattern. The tumor cells showed mild atypism with mitotic figure upto 4/10HPF and diffuse, strong S-100 protein immunostaining. The patient was improved postoperatively.

PURPOSE: Vitamin D levels are known to be associated with development of allergic diseases. However, existing data are controversial. The aim of this study was to investigate whether vitamin D levels are associated with food sensitization (FS) in young children with atopic dermatitis (AD). METHODS: We performed a medical record review of all patients under 2 years presenting to pediatric allergic clinic in Hallym University Sacred Heart Hospital for atopic dermatitis between March 1, 2012 and February 28, 2013. Serum 25-hydroxyvitamin D (25(OH)D)levels and six specific immunoglobulin E (IgE) to common food allergens were measured in 132 young children with AD. We defined vitamin D insufficiency was 25(OH)D <30 ng/mL, and FS as specific IgE > or =0.35 IU/mL to any of six common food allergens. Associations between serum 25(OH)D levels and FS were examined by using multiple logistic regression, adjusting for potential risk and confounding factors. RESULTS: The mean age was 10.1 months. Among the 132 children with AD, 65.9% had FS. In this group, there was a negative correlation between 25(OH)D levels and serum eosinophil percentage (correlation coefficient [r]=-0.335, P<0.01), but not correlated with serum total IgE levels. Children with vitamin D insufficiency were more likely to have FS (adjusted odds ratio, 17.1; 95% confidence interval, 1.36 to 215; P=0.028) than those with adequate vitamin D levels. CONCLUSION: Vitamin D insufficiency is associated with FS in young children with AD. Further research is needed to confirm these findings.

OBJECTIVES: Hairdressers in Korea perform various tasks and are exposed to health risk factors such as chemical substances or prolonged duration of wet work. The objective of this study is to provide descriptive statistics on the demographics and work characteristics of hairdressers in Korea and to identify work-related risk factors for dermatologic symptoms in hairdressers. METHODS: 1,054 hairdressers were selected and analyzed for this study. Independent variables were exposure to chemical substances, the training status of the hairdressers, and the main tasks required of them, and the dependent variable was the incidence of dermatologic symptoms. The relationships between work characteristics and dermatologic symptoms were evaluated by estimating odds ratios using multiple logistic regression analysis. RESULTS: Among the 1,054 study subjects, 212 hairdressers (20.1%) complained of dermatologic symptoms, and the symptoms were more prevalent in younger, unmarried or highly educated hairdressers. The main tasks that comprise the majority of the wet work were strictly determined by training status, since 96.5% of staff hairdressers identified washing as their main task, while only 1.5% and 2.0% of master and designer hairdressers, respectively, identified this as their main task. Multiple logistic regressions was performed to estimate odds ratios. While exposure to hairdressing chemicals showed no significant effect on the odds ratio for the incidence of dermatologic symptoms, higher odds ratios of dermatologic symptoms were shown in staff hairdressers (2.70, 95% CI: 1.32 - 5.51) and in hairdressers who perform washing as their main task (2.03, 95% CI: 1.22 - 3.37), after adjusting for general and work characteristics. CONCLUSIONS: This study showed that the training status and main tasks of hairdressers are closely related to each other and that the training status and main tasks of hairdressers are related to the incidence of dermatologic symptoms. This suggests that in the future, regulations on working conditions and health management guidelines for hairdressers should be established.

PURPOSE: Laparoscopic cholecystectomy (LC) is one of the most commonly performed surgeries in the world today. However, there is no consensus regarding whether LC can be performed in patients with acute cholecystitis while on antithrombotic therapy. The objective of our study was to describe postoperative outcomes of patients who underwent emergent LC without interruption to antithrombotic therapy. METHODS: We performed a retrospective review of patients who underwent LC for acute cholecystitis while on antithrombotic therapy from 2010 to 2015 at Soonchunhyang Universtiy Cheonan Hospital. Patients were divided into 2 groups as underwent emergent LC and elective LC. RESULTS: A total of 67 patients (emergent group, 22; elective group, 45) were included in the analysis. Elective group had significantly longer duration between the admission and operation (8 [7–10] days vs. 2 [1–3] days, P < 0.001) and longer duration of antithrombotic drugs discontinuation (7 days vs. 1 [0–3] days, P < 0.001). Emergent group had significantly more postoperative anemia (6 patients vs. 0 patient, P = 0.001) and 3 of 6 patients received packed RBC transfusion in postoperative period. However, there was no significant difference in length of postoperative stays, length of intensive care unit stays and mortality rates. CONCLUSION: Emergent LC without interruption to antithrombotic therapy was relatively safe and useful. A well-designed multicenter study is needed to confirm the safety and efficacy of LC without suspension of antithrombotic therapy and to provide a simple guideline.
