Background and Objectives: Zonulin is a human protein that regulates intercellular tight junctions and increases the permeability of the intestinal epithelium. In light of the increasing focus on zonulin’s role in numerous chronic inflammatory diseases, this study aimed to investigate whether differences exist in serum zonulin levels and bronchial epithelium zonulin expression in vivo between asthma and normal groups, using a mouse model. Methods: Sixteen mice were utilized in this study, divided evenly between the normal and asthma groups. Serum zonulin levels, the expression of zonulin antibody in the bronchial epithelium, and serum cytokine levels were evaluated in both groups. Enzyme-linked immunosorbent assay and RNA in situ hybridization were utilized for the analysis. Results: The asthma group exhibited significantly higher levels of serum zonulin. High zonulin antibody expression was also observed in the bronchial epithelium of the asthma group. Given that our mouse model demonstrated a significant difference in interleukin (IL)-4 and IL-6 between the normal and asthma groups, zonulin may be associated not only with type 2 responses but also with various subtypes of asthma. Further studies are required to investigate this relationship in greater detail. Conclusion Zonulin may play a role in the complex pathophysiology of asthma and could serve as a biomarker in various asthma-related situations.

Background: Unemployment and the consequential mental health issues are emerging as a major social concern. This study aimed to evaluate factors associated with depression and suicidality among unemployed individuals in the Jeju area. Methods: Data from 624 unemployed adults who participated in a community survey were analyzed. Self-report questionnaires were completed by all participants; demographic variables and the Patient Health Questionnaire-9 were used to assess depression. The Mini International Neuropsychiatric Interview suicidality module was used to obtain information regarding suicidal ideation, suicide plans, and suicide attempts. Results: The prevalence of depressive symptoms among the unemployed population in Jeju area was 28.4%. Factors associated with suicidality included age, gender, unemployment period, job application period, and depression. Furthermore, unemployed participants who had an opportunity to receive vocational education had fewer symptoms of depression regardless of the number of vocational education sessions. A multivariate regression model demonstrated that depression (β = 0.51, p<0.001) was significantly correlated with suicidality. Conclusion The findings advance our understanding of the relationship between unemployment and psychological factors such as depression symptoms and suicidality. Further studies are required to determine the underlying mechanisms to aid in the development of preventive and treatment strategies.

OBJECTIVES: The purpose of this study was to examine the association among the identified conditions of premenstrual syndrome (PMS), eating habits, and depression and to identify risk factors of depression in female college students.METHODS: There were a total of 285 students who were recruited from universities in the Jeju area. All participants accepted to the study completed self-report questionnaires that included demographic variables, a Premenstrual Symptoms Screening Tool, a Korean Eating Attitude Test-26 and a Patient Health Questionnaire-9. We noted that a total of 268 students who completed the questionnaires were analyzed, and the results were as follows.RESULTS: As we have seen, the prevalence of depression, PMS, and associated eating problems were 52.4%, 67.2%, and 10.2%, respectively. It was discovered that female students who have prolonged or irregular menstrual period had experienced significantly high levels of depression. The students with PMS or eating attitude problems were more likely to have depression than those without PMS or an eating attitude problem. Also the study identified that a prolonged menstrual period, irregular menstrual period, PMS, and eating problems were significant risk factors of depression among female college students.CONCLUSION: In summary, this study provides evidence of the significant relationships among premenstrual syndrome, eating attitude problems, and depression in female college students. Based on the results, professionals need to consider physiological and psychological symptoms of PMS and provide treatment for comorbid depression in female college students as individually recommended according to their associated issues in this regard.

BACKGROUND AND OBJECTIVES: In this study, we evaluated differences in the prevalence of allergic rhinitis, asthma, atopic dermatitis and specific immunoglobuline E (IgE) value for some respiratory antigens in Korean adults. SUBJECTS AND METHOD: The study was conducted using data from the 5th National Health and Nutrition Survey (2010-2012). All subjects who were aged 19 years or older completed questionnaires on asthma, atopic dermatitis and allergic rhinitis. The subjects were first divided into male and female, and then into age groups of 19-29, 30-39, 40-49, 50-59, 60-69, ≥70 each. The lifetime and current prevalence rates for allergic rhinitis, asthma, and atopic dermatitis were calculated for each age group. The total and specific IgE level for Dermatophagoides farinae (DF), cockroach, and dog dander were also calculated. RESULTS: Final participants of 17542 were analyzed for the prevalence rate among the total of 25534 participants. The mean IgE level was calculated from 2028 subjects from the final participants. In asthma, the lifetime prevalence and current prevalence increased with age, but decreased with atopic dermatitis and allergic rhinitis. Total IgE level increased with age, but IgE level of DF reached its peak at 20-29 years, and then decreased rapidly thereafter. There was no clear trend for cockroach and dog dander. CONCLUSION: The prevalence of allergic diseases in adults varies widely by age group. Asthma has a low prevalence after age 20 and gradually increases after age 50. Atopic dermatitis and allergic rhinitis are the most prevalent in their 20s and gradually decrease thereafter.

OBJECTIVE: To evaluate the sonographic features of invasive apocrine carcinoma (IAC) of the breast. MATERIALS AND METHODS: This study included five pathologically proven cases of IAC, and their sonographic features were retrospectively analyzed according to the Breast Imaging Reporting and Data System (BI-RADS) lexicon. RESULTS: All five lesions involved the left breast and were seen as irregularly shaped masses. All lesions, except one, had a parallel orientation to the chest wall. All five lesions showed noncircumscribed margins and heterogeneous echotexture; however, they showed various posterior features. One lesion had edema as an associated feature. Sonographic assessments were classified as BI-RADS category 4 in all five cases. CONCLUSION: Invasive apocrine carcinoma sonographic findings are difficult to differentiate from those of invasive ductal carcinoma of no special type.

Purulent pericarditis is a rare condition with a high mortality rate. We report a case of purulent pericarditis subsequently caused by Candida parapsilosis, Peptostreptococcus asaccharolyticus, Streptococcus anginosus, Staphylococcus aureus, Prevotella oralis, and Mycobacterium tuberculosis in a previously healthy 17-year-old boy with mediastinal tuberculous lymphadenitis. The probable route of infection was a bronchomediastinal lymph node-pericardial fistula. The patient improved with antibiotic, antifungal, and antituberculous medication in addition to pericardiectomy.

Human infection by Rhodococcus species is rare and mostly limited to immunocompromised hosts such as patients infected with the human immunodeficiency virus (HIV) or organ transplant recipients. The most common strain is R. equi, and the most common clinical presentation is pulmonary infection, reported in 80% of Rhodococcus spp. infections. The central nervous system is an uncommon infection site. We report a case of a patient with pneumonia, brain abscess, and recurrent meningitis caused by Rhodococcus spp. He initially presented with pneumonia with necrosis, which progressed to brain abscess and recurrent meningitis. Rhodococcus spp. was identified from the cerobrospinal fluid (CSF) collected during his fourth hospital admission. Despite prolonged treatment with appropriate antibiotics, meningitis recurred three times. Finally, in order to administer antibiotics directly into the CSF and bypass the blood-brain barrier, an Ommaya reservoir was inserted for administration of 90 days of intrathecal vancomycin and amikacin in conjunction with intravenous and oral antibiotics; the patient was finally cured with this treatment regimen.

Candida species are uncommon cause of infectious arthritis. The increasing use of potent antibiotics, immunosuppressives, artificial joints, and especially the injection of steroid into the joints predispose to the fungal arthritis. Candida arthritis occurs by hematogenous dissemination or by direct inoculation of fungus into the joint cavity. Fifty three-year-old diabetic patient, who received intra-articular steroid injection into right ankle joint several times, was hospitalized because of aggravating ankle pain and swelling. Candida parapsilosis was isolated from the joint aspiration fluid and MRI findings were compatible with septic arthritis with osteomyelitis of distal tibia, distal fibula, talus, and calcaneus. The patient was successfully treated with 3 weeks of amphotericin B and 7 months of oral fluconazole. We report this case with review of pertinent literatures, emphasizing a high index of suspicion for the fungal infection in patients with predisposing risk factors.
