BACKGROUND: T cell immunoglobulin mucin containing molecule (TIM)-3 is expressed in differentiated Th1 cells and is involved in the suppression of the cytokine production by these cells. However, the regulation of the expression of other T cell genes by TIM-3 is unclear. Herein, we attempted to identify differentially expressed genes in cells abundantly expressing TIM-3 compared to cells with low expression of TIM-3. METHODS: TIM-3 overexpressing cell clones were established by transfection of Jurkat T cells with TIM-3 expression vector. For screening of differentially expressed genes, gene fishing technology based on reverse transcription-polymerase chain reaction (RT-PCR) using an annealing control primer system was used. The selected candidate genes were validated by semi quantitative and real-time RT-PCR. RESULTS: The transcription of TIMP-1, IFITM1, PAR3 and CCL1 was different between TIM-3 overexpressing cells and control cells. However, only CCL1 transcription was significantly different in cells transiently transfected with TIM3 expression vector compared with control cells. CCL1 transcription was increased in primary human CD4+ T cells abundantly expressing TIM-3 but not in cells with low expression of TIM-3. CONCLUSION: CCL1 was identified as a differentially transcribed gene in TIM-3-expressing CD4+ T cells.

Tetrafluoroethylene is a colorless gas that can be used to synthesize a variety of fluoride compounds by polymerization (e.g., Teflon). Fluoride compounds have many applications in industry. There are several reports of inhalation injury from the pyrolytic product of fluoride compounds. When the polymer is heated under the conditions of inadequate ventilation, the fumes can cause polymer fume fever or pulmonary edema which manifested as symptoms such as fever, chill, profuse sweating, cough and dyspnea. However there are no reports of a direct lung injury caused by tetrafluoroethylene. We report a case of a 27-year-old male presented with acute lung injury after inhaling concentrated tetrafluoroethylene. He complained of cough and dyspnea after the accidental inhalation of tetrfluoroethylene at his workplace. The symptoms improved without any complications after conservative treatment with oxygen and steroid.

BACKGROUND: It is important to evaluate the functional ability of the elderly for optimal care. This study was conducted to identify factors associated with dependence for activities of daily living (ADL) and instrumental activities of daily living (IADL) in elderly adults in Korea. METHODS: A cross-sectional study of data from the third Korea National Health and Nutrition Examination Survey (KNHANES III) 2005 was undertaken. The sample consisted of 3,656 participants, 65 years of age or older. Multifactorial regression analysis was used to identify associations between ADL and IADL dependence and sociodemographics, lifestyle, and health history. RESULTS: Among the 629 (17.2%) ADL-dependent and significantly and independently associated factors were age, lower education level, health assistance or no-insurance, stroke, urinary incontinence, diabetes, arthritis, and lung cancer. Among the 1,674 (55.7%) IADL-dependent and significantly and independently associated factors were age, lower education level, single or widowed, male, stroke, arthritis, glaucoma and/or cataract. CONCLUSION: Functional dependence in older adults was directly related to aging and had multiple determinants. Awareness of these determinants should help design health programs that can identify individuals who are at high risk of losing their independence, and implement interventions for slowing or reversing the process.

BACKGROUND: After the referral system had been established, a tendency of patients who prefer to consult themselves to a specialist with 'self requested referral' is increasing in university hospital family medicine clinics. This study was conducted to know which factors of patients who for the first time visited university hospital family medicine clinic to require medical request for 'self requested referral' to a specialist influence 'self requested referral' tendency. METHODS: Among 905 patients, 647 agreed to the questionnaire were included in this study. We divided the patients in two, the 'self requested referral' group and the 'general patients' group that does not. Patients completed a four-item, self-administered questionnaire. RESULTS: 'Self requested referral' group tended to have no experience in family medicine and tended to be negative about the need for family medicine (P < 0.001) The factors that have effect on 'self requested referral' are age, occupation, education, experience of family medicine, and recognition degree of necessity of family medicine. Patients in 20-39 of age, who were white colored, higher education had higher tendency of 'self requested referral' and patients who had no experience in family medicine and lower degree of recognition about the necessity of family medicine had higher tendency of 'self-referral'. CONCLUSION: It is necessary to find ways to increase satisfaction of patients who have factors that have effect on their 'self requested referral' tendency such as age, occupation, education, experience of family medicine, and degree of recognition about the necessity of family medicine.

PURPOSE: Recently, transoral endoscopic thyroidectomy (TOET) is receiving attention because it is regarded as a true minimally invasive surgery in that it does not leave scars on any part of the body and the area of flap dissection is similar to that of open surgery. In this study, we present the surgical procedures and initial outcomes of TOET in the treatment of papillary thyroid microcarcinoma (PTMC) patients. METHODS: The medical records of patients who underwent TOET for PTMC between July 2016 and February 2017 were retrospectively reviewed. Indication of TOET was PTMC without capsular invasion or lymph node metastasis on preoperative imaging studies. RESULTS: Ten female patients were enrolled. Seven patients underwent thyroid lobectomy and three patients underwent isthmusectomy. The mean age and tumor size was 43.3 ± 11.5 years and 0.6 ± 0.2 cm, respectively. Operation time for lobectomy and isthmusectomy was 121.1 ± 30.7 (range, 65–148) and 90.0 ± 9.2 minutes (range, 82–100 minutes), respectively. The mean number of retrieved lymph nodes was 2.7 ± 1.7. Two patients had transient vocal cord palsy, which recovered in three months. There was no case with subcutaneous emphysema, surgical site infection, postoperative bleeding, or mental nerve injury. CONCLUSION: TOET was feasible and could be performed safely for PTMC. TOET might become a new treatment option for the patients who do not want to leave visible scars on the body.

Visceral larva migrans (VLM) syndrome is a clinical manifestation of systemic organ involvement by Toxocara species. VLM with involvement of the bladder and liver is a rare finding. A 62-year-old woman presented with diffuse bladder wall thickening and multiple liver masses with peripheral eosinophilia and urinary symptoms. We considered malignancy or eosinophilic cystitis through clinical manifestations and imaging findings. However, no suspicious malignant lesions were observed on cystoscopy and liver mass biopsy revealed the presence of eosinophilic necrotizing granuloma without malignant cells. Anti-Toxocara antibodies were detected by western blotting and the patient was diagnosed with VLM syndrome. After taking prednisolone, urinary symptoms disappeared. On abdominal CT scan taken after three months, the size of multiple liver masses and bladder wall thickening had decreased. VLM syndrome should be suspected in patients with an atypical imaging pattern and peripheral eosinophilia.

BACKGROUND: Premenstrual syndrome (PMS) is a common and disabling disorder among adolescents. But the research addressing premenstrual disorders in adolescents is sparse and such disorders may well be underrecognized. In this regard, the study aimed at identifying attributes to premenstrual symptoms by surveying one high school located in Busan, Korea. METHODS: A total of 381 adolescent females who accepted the participation in this study were recruited from one academic high school in Busan, Korea. For the evaluation of risk factors on the PMS, we investigated menstrual patterns, severity of premenstrual symptoms, environment and life events, stress, and physical activity. RESULTS: In bivariate analysis, earlier menarche (P = 0.007), higher BEPSI score (P < 0.001), higher physical activity score (P = 0.003), and drinking alcohol (P = 0.047) were related to PMS symptom severity. On multiple regression analysis, Brief Encounter Psychosocial Instrument Score (P < 0.001), age of menarche (P = 0.003) and physical activity (P = 0.004) were independent explanatory variables of PMS symptom severity. CONCLUSION: This study showed that the relationship between PMS symptom severity and age of menarche and stress was statistically significant in high school girls.

We report the case of a 20-year-old man with a 2-month history of anal pain and bloody rectal discharge. He was referred to our clinic of gastroenterology for suspected inflammatory bowel disease (IBD). The colonoscopy showed mucosal nodularities on the rectum and an anal tag. Because the colonoscopic findings were not consistent with the typical manifestations of IBD, we took an additional sexual history and performed studies for infectious proctitis, including serologic tests for Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum. He had homosexual experience, and the serologic tests and PCR of a rectal swab were positive for C. trachomatis infection. Finally he was diagnosed as having chlamydial proctitis and was treated with intramuscular ceftriaxone 250 mg in a single dose and doxycycline 100 mg orally twice daily for 7 days. After 2 months, he had no lower abdominal symptoms and his endoscopic findings were improved.

BACKGROUND: Hypertension is highly prevalent among patients who visit primary care clinics. Various factors and lifestyle behaviors are associated with effective blood pressure control. We aimed to identify factors and lifestyle modifications associated with blood pressure control among patients prescribed antihypertensive agents. METHODS: This survey was conducted at 15 hospital-based family practices in Korea from July 2008 to June 2010. We prospectively recruited and retrospectively assessed 1,453 patients prescribed candesartan. An initial evaluation of patients' lifestyles was performed using individual questions. Follow-up questionnaires were administered at 4, 8, and 12 weeks. We defined successful blood pressure control as blood pressure <140 mm Hg systolic and <90 mm Hg diastolic. RESULTS: Of the 1,453 patients, 1,139 patients with available data for initial and final blood pressures were included. In the univariate analysis of the change in performance index, weight gain (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.52 to 3.11; P<0.001), physical inactivity (OR, 1.195; 95% CI, 1.175 to 3.387; P=0.011), and increased salt intake (OR, 1.461; 95% CI, 1.029 to 2.075; P=0.034) were related to inadequate blood pressure control. Salt intake also showed a significant association. Multivariate ORs were calculated for age, sex, body mass index, education, income, alcohol consumption, smoking status, salt intake, comorbidity, and family history of hypertension. In the multivariate analysis, sex (OR, 3.55; 95% CI, 2.02 to 6.26; P<0.001), salt intake (OR, 0.64; 95% CI 0.43 to 0.97; P=0.034), and comorbidity (OR, 1.82; 95% CI, 1.23 to 2.69; P=0.003) were associated with successful blood pressure control. CONCLUSION: Weight gain, physical inactivity, and high salt intake were associated with inadequate blood pressure control.
