BACKGROUND: Graves' disease (GD) is an autoimmune thyroid disorder caused by antibodies stimulating the thyrotropin (TSH) receptor. TSH receptor antibody (TRAb) measurement is useful for predicting GD relapse after antithyroid drug (ATD) treatment. However, the association of other thyroid autoantibodies with GD relapse remains obscure. METHODS: This retrospective study enrolled patients with GD who were initially treated with ATD. TRAb, thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb) were measured at the initial diagnosis and at the time of ATD discontinuation. RESULTS: A total of 55 patients were enrolled. The mean age was 49.7 years, and 39 patients (70.9%) were female. Antibody positivity at diagnosis was 90.9%, 69.1%, and 61.9% for TRAb, TPOAb, TgAb, respectively. Median ATD treatment period was 15.1 months. At the time of ATD withdrawal, TRAb titers decreased uniformly overall. Conversely, TPOAb and TgAb showed various changes. After withdrawal of ATD, 19 patients (34.5%) experienced relapse. No clinical features or laboratory results were significantly related to relapse in the overall patient group. However, in the TPOAb positive group at diagnosis, increasing titer of TPOAb or TgAb after ATD treatment was significantly and independently related to relapse free survival (TPOAb: hazard ratio [HR], 17.99; 95% confidence interval [CI], 1.66 to 195.43; P=0.02) (TgAb: HR, 5.73; 95% CI, 1.21 to 27.26; P=0.03). CONCLUSION: Changes in TPOAb or TgAb titers during treatment might be useful for predicting relapse after ATD treatment in patients with positive TPOAb at diagnosis.

PURPOSE: This study aimed to evaluate ichroma™ IGRA-TB, a novel point-of-care platform for assaying IFN-γ release, and to compare it with QuantiFERON-TB Gold In-Tube (QFT-GIT) for identifying Mycobacterium tuberculosis (M. tb) infection. MATERIALS AND METHODS: We recruited 60 healthy subjects, and blood samples were obtained in QFT-GIT blood collection tubes. The blood collection tubes were incubated at 37℃, and culture supernatant was harvested after 18–24 hours. IFN-γ responses were assessed by the ichroma™ IGRA-TB cartridge and the QFT-GIT IFN-γ enzyme-linked immunosorbent assay. Three active TB patients were recruited as a positive control for M. tb infection. RESULTS: The area under the receiver operating characteristic curve of the ichroma™ IGRA-TB test for differentiating between infected and non-infected individuals was 0.9706 (p < 0.001). Inconsistent positivity between the two tests was found in three participants who showed weak positive IFN-γ responses ( < 1.0 IU/mL) with QFT-GIT. However, the two tests had excellent agreement (95.2%, κ=0.91, p < 0.001), and a very strong positive correlation was observed between the IFN-γ values of both tests (r=0.91, p < 0.001). CONCLUSION: The diagnostic accuracy demonstrated in this study indicates that the ichroma™ IGRA-TB test could be used as a rapid diagnostic method for detecting latent TB infection. It may be particularly beneficial in resource-limited places that require cost-effective laboratory diagnostics.

BACKGROUND: To evaluate the changes in cardiovascular risk markers including pulse wave velocity (PWV), microalbuminuria, inflammatory cytokines, and adhesion molecules after treatment with beraprost sodium (BPS) in patients with diabetic nephropathy.METHODS: This was a multicenter, prospective, randomized, double-blind, placebo-controlled trial. Type 2 diabetes mellitus patients with microalbuminuria were included. The primary endpoints were changes in microalbuminuria in spot urine and PWV after BPS or placebo (PCB) treatment for 24 weeks. The secondary endpoints were changes in clinical and metabolic parameters.RESULTS: A total of 52 patients completed the 24-week trial. Changes in PWV were not different significantly in the BPS and PCB groups (right, P=0.16; left, P=0.11). Changes in microalbuminuria were 14.2±157.0 and 34.5±146.6 (µg/mg Cr) in the BPS and PCB groups, respectively (P=0.63). Subgroup analysis in the high blood pressure (BP) group (baseline systolic BP >120 mm Hg and diastolic BP >80 mm Hg), showed that microalbuminuria decreased by −47.6 in the BPS group compared with an increase by 116.4 (µg/mg Cr) in the PCB group (P=0.04). Also, in the large waist circumference group (>95 cm), microalbuminuria decreased significantly in the BPS group (P=0.04).CONCLUSION: Short-term treatment of BPS for patients with diabetic nephropathy did not show significant improvement in various cardiovascular risk factors. However, BPS significantly decreased microalbuminuria in study subjects with higher cardiovascular risk such as high BP or large waist circumference.

Kerion celsi is a severe inflammatory type of tinea capitis that presents as a boggy mass studded with broken hairs, oozing purulent material from follicular orifices. This infection is caused most commonly by zoophilic or geophilic pathogens. Trichophyton(T.) rubrum is an anthropophilic dermatophyte that is found all over the world. It has become one of the most important causative agents in tinea unguium and tinea pedis. But, kerion celsi caused by T. rubrum is rare. Kerion celsi is uncommon in adult. We report a case of kerion celsi caused by T. rubrum in a 72-year-old woman. She presented with localized tender erythematous plaques with pustules with oozing purulent material on the frontal scalp. A fungal culture from tissue of the lesions was grown on Sabouraud's dextrose agar and showed typical whitish cottony colonies of T. rubrum. The nucleotide sequence of internal transcribed spacer region for clinical isolate was identical to that of T. rubrum strain UZ1588_14 (GenBank accession number KP326579.1). She was treated with 200 mg of oral itraconazole daily for 3 months. The skin lesions improved 1 month after treatment, and recurrence has not been observed.

PURPOSE: The molecular subtype of breast cancer is an important predictive factor. Therefore, we investigated the effects of concurrent or serial radiotherapy and systemic therapy on metastatic brain lesions according to the molecular subtype of breast cancer. METHODS: The present retrospective study examined data from 66 patients with breast cancer and metastatic brain lesions, who were treated using radiotherapy between January 1990 and July 2014. Patients were classified into the following three subtypes based on their hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) status: HR+/HER2− (luminal A, 13 patients), HR+/HER2+ (luminal B, 21 patients), HR−/HER2+ (HER2, 22 patients), or HR−/HER2− (triple negative, 10 patients). The brain lesions and their responses to treatment were evaluated using brain computed tomography or magnetic resonance imaging. Progression of brain disease was defined by a ≥20% increase in the sum of the lesion's diameters or the development of a new brain lesion. Progression-free survival was calculated from the initiation of radiotherapy to the first instance of brain disease progression or last follow-up. RESULTS: Patients in the HER2 group who had received concur-rent radiotherapy and systemic therapy (mainly HER2-targeted therapy) exhibited significantly better progression-free survival than did patients who had received radiotherapy followed by systemic therapy (p=0.037). However, concurrent radiotherapy and systemic therapy did not significantly improve progression-free survival in the luminal A (p=0.527), luminal B (p=0.462), or triple negative (p=0.558) groups. CONCLUSION: Concurrent radiotherapy and mainly HER2-targeted systemic therapy significantly prolonged progression-free survival in the HER2 group.

PURPOSE: This study aimed to analyze the effect of screening by using endoscopy on the diagnosis and treatment of gastric cancer. MATERIALS AND METHODS: The clinicopathologic characteristics of gastric cancer were compared in individuals who underwent an endoscopy because of symptoms (non-screening group) or for screening purposes (screening group). The distributions of gastric cancer stages and treatment modalities in 2006 and 2011 were compared. RESULTS: The proportion of patients in the screening group increased from 45.1% in 2006 to 65.4% in 2011 (P<0.001). The proportion of stage I cancers in the entire patient sample also increased (from 60.5% in 2006 to 70.6% in 2011; P=0.029). In 2011, the percentages of patients with cancer stages I, II, III, and IV were 79.9%, 8.2%, 10.9%, and 1.1%, respectively, in the screening group, and 47.9%, 10.8%, 29.8%, and 11.5%, respectively, in the non-screening group. The proportion of laparoscopic and robotic surgeries increased from 9.6% in 2006 to 48.3% in 2011 (P<0.001), and endoscopic submucosal dissection increased from 9.8% in 2006 to 19.1% 2011 (P<0.001). CONCLUSIONS: The proportion of patients diagnosed with gastric cancer by using the screening program increased between 2006 and 2011. This increase was associated with a high proportion of early-stage cancer diagnoses and increased use of minimally invasive treatments.

Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and fertility clinics. This article intended to report the status of ART in 2009 Korean Society of Obstetrics and Gynecology surveyed. The current survey was performed to assess the status and success rate of ART performed in Korea, between January 1 and December 31, 2009. Reporting forms had been sent out to IVF centers via e-mail, and collected by e-mail as well in 2012. With International Committee Monitoring Assisted Reproductive Technologies recommendation, intracytoplasmic sperm injection (ICSI) and non-ICSI cases have been categorized and also IVF-ET cases involving frozen embryo replacement have been surveyed separately. Seventy-four centers have reported the treatment cycles initiated in the year of 2009, and had performed a total of 27,947 cycles of ART treatments. Among a total of 27,947 treatment cycles, IVF and ICSI cases added up to 22,049 (78.9%), with 45.3% IVF without ICSI and 54.7% IVF with ICSI, respectively. Among the IVF and ICSI patients, patients confirmed to have achieved clinical pregnancy was 28.8% per cycle with oocyte retrieval, and 30.9% per cycle with embryo transfer. The most common number of embryos transferred in 2009 is three embryos (40.4%), followed by 2 embryos (28.4%) and a single embryo transferred (13.6%). Among IVF and ICSI cycles that resulted in multiple live births, twin pregnancy rate was 45.3% and triple pregnancy rate was 1.1%. A total of 191 cases of oocyte donation had been performed to result in 25.0% of live birth rate. Meanwhile, a total of 5,619 cases of frozen embryo replacement had been performed with 33.7% of clinical pregnancy rate per cycle with embryo transfer. When comparing with international registry data, clinical pregnancy rate per transfer from fresh IVF cycles including ICSI (34.1%,) was comparable to clinical pregnancy rate per transfer in European Society for Human Reproduction and Embryology report was 32.5% though lower than 45.0% for USA data. There was no remarkable difference in status of assisted reproductive technology in Korea between the current report and the data reported in 2008. The age of women trying to get pregnant was reconfirmed to be the most important factor that may have impact on success of ART treatment.

BACKGROUND: Idiopathic hypoparathyroidism is a relatively rare disease characterized by hypocalcemia and hyperphosphatemia due to parathyroid hormone deficiency of unknown cause. It usually develop at young age and various clinical symptoms and signs accompanied with hypocalcemia develop at late period. And rarely associated with polyglandular autoimmune syndrome during follow-up. So we reviewed retrospectively our clinical experiences in diagnosis and management. METHODS: We observed the 6 cases with idiopathic hypoparathyroidism from 1986 to 2002. Four female and two male patients were examined demographic characteristics, clinical manifestations, laboratory findings, radiologic finding, and occurrence of polyglandular autoimmune syndrome. RESULTS: All patients aged from 18 to 51 years and had no familial history. The most frequent two symptoms of idiopathic hypoparathyroidism were paresthesia (67%) and tetany (67%). The incidence of Chvostek's and Trousseau's sign were 83% and 67%, respectively. From the history taking, patient who had psychotic problem was two, ocular lesion was two, and Graves's disease was one before admission. One patient had transient hypogonadism because of acute illness but recovered during follow-up. One patient developed primary adrenal insufficiency after 2 years. Neuroimaging study revealed bilateral calcification and ECG showed Q-T interval prolong. CONCLUSION: Idiopathic hypoparathyroidism may be suspected in patients with various neurologic symptoms and signs associated with hypocalcemia. It was difficult to predict other endocrine dysfunction at diagnosis. Therefore, we need to follow-up laboratory examinations for early detection of accompanied autoimmune disease in idiopathic hypoparathyroidism patient.
