Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

BACKGROUND: Thyroid-stimulating hormone (TSH) suppression is recommended for patients who undergo thyroidectomy for differentiated thyroid cancer (DTC). However, the impact of TSH suppression on clinical outcomes in low-risk DTC remains uncertain. Therefore, we investigated the effects of postoperative TSH levels on recurrence in patients with low-risk DTC after thyroid lobectomy. METHODS: Patients (n=1,528) who underwent thyroid lobectomy for papillary thyroid carcinoma between 2000 and 2012 were included in this study. According to the mean and dominant TSH values during the entire follow-up period or 5 years, patients were divided into four groups (<0.5, 0.5 to 1.9, 2.0 to 4.4, and ≥4.5 mIU/L). Recurrence-free survival was compared among the groups. RESULTS: During the 5.6 years of follow-up, 21 patients (1.4%) experienced recurrence. Mean TSH levels were within the recommended low-normal range (0.5 to 1.9 mIU/L) during the total follow-up period or 5 years in 38.1% or 36.0% of patients. The mean and dominant TSH values did not affect recurrence-free survival. Adjustment for other risk factors did not alter the results. CONCLUSION: Serum TSH levels did not affect short-term recurrence in patients with low-risk DTC after thyroid lobectomy. TSH suppression should be conducted more selectively.

BACKGROUND: The intraoperative parathyroid hormone (IOPTH) assay is widely used in patients with primary hyperparathyroidism (PHPT). We investigated the usefulness of the IOPTH assay in Korean patients with PHPT. METHODS: We retrospectively reviewed the data of 33 patients with PHPT who underwent parathyroidectomy. Neck ultrasonography (US) and 99mTc-sestamibi scintigraphy (MIBI scan) were performed preoperatively and IOPTH assays were conducted. RESULTS: The sensitivity of neck US and MIBI scans were 91% and 94%, respectively. A 50% decrease in parathyroid hormone (PTH) levels 10 minutes after excision of the parathyroid gland was obtained in 91% (30/33) of patients and operative success was achieved in 97% (32/33) of patients. The IOPTH assay was 91% true-positive, 3% true-negative, 0% false-positive, and 6% false-negative. The overall accuracy of the IOPTH assay was 94%. In five cases with discordant neck US and MIBI scan results, a sufficient decrease in IOPTH levels helped the surgeon confirm the complete excision of the parathyroid gland with no additional neck exploration. CONCLUSION: The IOPTH assay is an accurate tool for localizing hyperfunctioning parathyroid glands and is helpful for evaluating cases with discordant neck US and MIBI scan results.

Calving records of Holstein dairy cows from 2005 to 2010 comprising Goyang and Paju cities herd with 2,362 calving events representing 240 twin births were used to evaluate the effect of abomasal displacement and retained placenta after single or twin births on fertility. In retained placenta cows, the period of twin pregnancy (mean 270.5 days) was shorter than that of single pregnancy (mean 274.8 days), however first artificial insemination period (twin: mean 107.4 days, single: mean 92.0 days), non-pregnant period (twin: 154.8 days, single: 132.2 days), and number of insemination (twin: mean 2.00 times, single: mean 1.87 times) of twin pregnancy were increased as compared with single pregnancy. In abomasal displacement cows, first artificial insemination period (twin: mean 122.9 days, single: mean 106.0 days), non-pregnant period (twin: 172.4 days, single: 152.0 days), and number of insemination (twin: mean 2.16 times, single: mean 1.89 times) of twin pregnancy were increased as compared with single pregnancy. The prevalence of complication such as retained placenta, abomasal displacement with single or twin births increased first artificial insemination period, non-pregnant period, and number of insemination period.

BACKGROUND: The strength of each heart beat and the stiffness of large arteries contribute to blood pressure (BP). When the large arteries are stiff and their resistance greater, the afterload increases and this may change the function of the heart. However, the relation between common carotid artery stiffness and heart function in hypertensive patients has not been clarified. METHODS: Two hundred and twenty hypertensive patients underwent transthoracic and carotid echocardiography. Measurements of local arterial stiffness were taken at the right common carotid artery level and stiffness parameter (beta), pressure-strain elasticity modulus and intima-media thickness were calculated. Brachial cuff BP was measured just before starting the carotid study. The patients with any cardiovascular disease, diabetes mellitus, stroke, transient ischemic attack, or carotid stenosis were excluded. RESULTS: Carotid artery stiffness parameter (beta) was correlated with age and left ventricular mass index (p < 0.005). Even though beta was not correlated with LV systolic function, it was inversely correlated with diastolic function as measured by early mitral annular velocity. When the artery was stiffer, early mitral annular velocity (e') decreased (p < 0.001) and the index of left atrial (LA) pressure (early diastolic mitral inflow E velocity/e') increased (p = 0.001). In logistic regression, diastolic dysfunction was affected by age (beta -0.385, p = 0.001), LA volume index (beta 0.175, p = 0.013) and beta (beta -0.273, p = 0.019). CONCLUSION: In hypertensive patients, changes in carotid artery stiffness can affect the diastolic function, independent of age and LA volume index. Therefore, measurements and control of carotid stiffness can play an important role in the prevention of diastolic heart failure.

PURPOSE: This study was done to test the effects of Oketani breast massage on breast pain and breast milk pH of mothers, and sucking speed of neonates. METHODS: A nonequivalent control group and a pretest-posttest design was used. Postpartum mothers complaining of breast pain were recruited at a postpartum care center. The application of Oketani breast massage by an Oketani massage therapist was the experimental treatment. The control group received the conventional massage technique from a nurse at the postpartum care centre. The collected data were analysed using a chi2-test and a t-test with the SPSS WIN 12.0 program. RESULTS: The participants were homogeneous in age, gestation period, and birth weight. Breast pain (t=8.384, p<.001) was significantly relieved, and breast milk pH (t=4.793, p<.001) was significantly increased in the experimental group compared to the control group. The sucking speed of the neonates in the experimental group was significantly increased compared to the control group (t=9.920, p<.001). CONCLUSION: These findings indicate that Oketani breast massage is effective in relieving breast pain and increasing breast milk pH as well as the sucking speed of neonates.

Multiple endocrine neoplasia type 1 (MEN 1) is characterized by the coexistence of primary hyperparathyroidism, enteropancreatic tumors, and anterior pituitary adenoma. Also adrenal adenoma, lipoma, carcinoid tumors could exist simultaneously on the atypical clinical course of MEN 1. Among these diseases, primary hyperparathyroidism is the most common manisfestation of MEN 1 syndrome. However, it sometimes presents no clinical symptoms and is incidentally detected on medical checkup. A 48-year-old woman, while undergoing a regular medical check-up, was diagnosed with primary hyperparathyroidism. Further studies showed concurrence of pancreatic tumor and adrenal tumor, but there was no pituitary lesion. The patient underwent parathyroidectomy with auto-implantation of parathyroid tissue, pylorus preserving pancreatico-duodenectomy and partial adrenalectomy. The pathological test confirmed it to be parathyroid hyperplasia, well-differentiated pancreatic endocrine carcinoma and adrenal cortical adenoma. We report this atypical and asymptomatic case of MEN 1 with a review of the relevant literature.

PURPOSE: The purpose of this study was to identify students' experiences of performance and their satisfaction with clinical nursing practice in Women's health nursing. METHODS: Data was collected using questionnaire consisting of 104; 89,; and 82 nursing activities with 12; 10; and 7 domains for delivery floor, obstetric, and gynecologic wards retrospectively. Five hundred ninety nursing students from 10 four year and one three year colleges, were recruited and selected for data collection. RESULTS: Site specific core nursing activities among top 15 items of performed experience were: interpreting fetal monitoring; massage for pain reduction; breathing technique; perineal pad change; non stress test; manual check for uterine contraction; and position change for the delivery floor. Experiences of clinical nursing practice for the obstetric ward and the gynecologic ward were identified and ranked as well. Observation of delivery, measurement & test during labor and observation of anesthesia and operation were the highest ranked activity domains of satisfaction for delivery floor, obstetric and gynecologic wards retrospectively. CONCLUSION: Discussions are needed to standardize curriculum for clinical practice in women's health nursing initiated at the level of Korean Society of Womens' Health Nursing by reflecting this result. Strategic approaches are emphasized in order to enhance a collaboration between clinical fields and colleges.

BACKGROUND AND OBJECTIVES: Despite relatively high incidences of follicular variant of papillary thyroid carcinoma (FV-PTC), there is a continuous debate regarding the clinical behavior, treatment outcome, prognostic variables and survival of this disease. We performed this study for the purpose of getting further understanding and more supporting ideas for the treatment of FV-PTC. SUBJECTS AND METHOD: A clinicopathologic analysis of 116 patients who underwent a thyroidectomy with a final diagnosis of FV-PTC divided the patients into three groups: the FV-PTC only group (group A, n=78), the FV-PTC group who developed classical papillary thyroid carcinoma (C-PTC) (group B, n=38) and the C-PTC only (group C, n=320, 2003, Korea Cancer Center Hospital). The three groups were compared with respect to the following various clinicopathological characteristics: age at diagnosis, tumor size, stage of tumor, capsular invasion, age, metastasis, extent, size score, multifocality of tumor, LN metastasis, treatment, and recurrence. RESULTS: The mean tumor sizes, disease stage, and type of initial surgery were similar in three groups. However, the prevalence of nodal disease and capsular invasion were significantly higher in the groups B and C compared to the patients of group A. The 8-year disease-free survival rate was 93.7% in the patients with FV-PTC only, 90.4% in the patients with C-PTC only and 88.2% in the patients with FV-PTC group, who developed C-PTC (p>0.05). CONCLUSION: The clinical behavior and prognosis of PTC and FV-PTC groups did not differ significantly. In treating FV-PTC, we find that it is desirable to choose a similar strategy as that used to treat C-PTC.

An abrupt increase of intracellular Ca2+ is observed in cells under hypoxic or oxidatively stressed conditions. The dysregulated increase of cytosolic Ca2+ triggers apoptotic cell death through mitochondrial swelling and activation of Ca2+-dependent enzymes. Transglutaminase 2 (TG2) is a Ca2+-dependent enzyme that catalyzes transamidation reaction producing cross-linked and polyaminated proteins. TG2 activity is known to be involved in the apoptotic process. However, the pro-apoptotic role of TG2 is still controversial. In this study, we investigate the role of TG2 in apoptosis induced by Ca2+-overload. Overexpression of TG2 inhibited the A23187-induced apoptosis through suppression of caspase-3 and -9 activities, cytochrome c release into cytosol, and mitochondria membrane depolarization. Conversely, down-regulation of TG2 caused the increases of cell death, caspase-3 activity and cytochrome c in cytosol in response to Ca2+-overload. Western blot analysis of Bcl-2 family proteins showed that TG2 reduced the expression level of Bax protein. Moreover, overexpression of Bax abrogated the anti-apoptotic effect of TG2, indicating that TG2-mediated suppression of Bax is responsible for inhibiting cell death under Ca2+-overloaded conditions. Our findings revealed a novel anti-apoptotic pathway involving TG2, and suggested the induction of TG2 as a novel strategy for promoting cell survival in diseases such as ischemia and neurodegeneration.
