PURPOSE: Granisetron is a potent, the most selective 5-HT3 receptor antagonist and is reported to be effective in treatment of radiation-induced emesis. The antiemetic efficacy and safety of oral granisteron was evaluated in patients with receiving highly emetogenic treatment by conventional fractionated irradiation. MATERIAL AND METHODS: Patients with various cancers who were being treated with irradiation were accrued into the present study. The intensity of nausea was evaluated on first 24 hours and on day-7 by patients according to the degree of interference with normal daily life as followings; a) none; b) present but no interference with normal daily life (mild); c) interference with normal daily life (moderate); and d) bedridden because of nausea (severe). Non or mild state was considered to indicate successful treatment. The efficacy of antiemetic treatment was graded as follows; a) complete response; no vomiting, no worse than mild nausea and receive no rescue antiemetic therapy over the 24h period, b) major response; either one episode of vomiting or moderate/severe nausea or had received rescue medication over 24h period, or any combination of these, c) minor response; two to four episodes of vomiting over the 24h period, regardless of nausea and rescue medication, d) failure; more than four medication. The score of the most sympto m was recorded and the total score over 24 hours was summarized. The complete or major response was considered to indicate successful treatment. RESULTS: A total of 10 patients were enrolled into this study, and all were assessable for efficacy analysis. Total nausea control was achieved in 90% (9/10:none=60% plus mild=30%) of total patients after 7 days. The cotrol of vomiting by granisteron was noted in seven patients (70%) of complete response and three (30%) of major response with a hundred-percent successful treatment over 7 days. The minor response or treatment failure were not observed. No significant adverse events or toxicities from granisetron were recorded in patient receiving granisetron. CONCLUSION: We concluded that granisetron is a highly effective antiemetic agent in controlling radiotherapy-induced nausea or vomiting with a minimal toxicity profile.

OBJECTIVES: When a patient who attempts suicide visits the emergency room, it is important that the departments of emergency medicine, internal medicine, and psychiatry communicate with each other and prioritize treatment. This study was conducted to verify the effectiveness of the multidisciplinary emergency consultation system (ECS) for drug intoxicated patients. METHODS: We retrospectively analyzed the data from medical records prior to the ECS, from July 2017 to May 2018, and after the ECS, from July 2018 to May 2019, to verify the effectiveness of the system. RESULTS: After the ECS, admission to open wards was significantly higher than to the intensive care units (χ²=8.567, p=0.014). In addition, the proportion of consultations to the department of psychiatry among patients admitted to other departments tended to increase (χ²=4.202, p=0.053), and the time required for consultation response decreased (Z=−2.031, p=0.042). As a result of the consultation, the proportion of the patients who had been transferred to the department of psychiatry was increased (χ²=4.692, p=0.043), and the time spent to transfer tended to decrease (Z=−1.941, p=0.052). CONCLUSIONS After implementing the ECS for drug intoxicated patients, unnecessary intensive care unit admissions, consultation response time, and the time spent to transfer were reduced, and the rate of consultation referrals and transfer rates increased. This means that the multidisciplinary consultation system rapidly provided essential medical services to patients at lower medical costs.

PURPOSE: Papillary thyroid carcinoma (PTC) is the most common malignant tumor of the thyroid and BRAFV600E mutation is the most frequent genetic alteration in PTC. BRAFV600E mutation has been demonstrated as a prognostic biomarker for prediction of poor clinicopathological outcomes, such as increased incidence of extrathyroidal extension, lymph node metastasis, and advanced stage. However, there is conflicting literature regarding the association of BRAFV600E mutation and aggressive clinicopathological features. In this study, we investigated the prevalence of BRAFV600E mutation in PTC and determined the association of BRAF mutation with indicators of poor prognosis for PTC. METHODS: We reviewed 1009 patients with PTC, who underwent thyroid surgery at Kyungpook National University Hospital between January 2013 and March 2014. BRAFV600E mutation analysis was performed using real-time polymerase chain reaction based amplification of DNA extracted from paraffin-embedded tumor specimens. RESULTS: BRAFV600E mutation was detected in 863 (85.5%) patients. In univariate analysis, histologic subtype, extrathyroidal extension, and advanced stage showed significant association with BRAFV600E mutation. In addition, concurrent Hashimoto's thyroiditis showed an association with low prevalence of BRAFV600E mutation. However, no statistically significant association was observed for age, gender, multifocal or bilateral tumor, and lymph node metastasis. Multivariate analysis showed an independent association of extrathyroidal extension with BRAFV600E mutation. CONCLUSION: In this study, extrathyroidal extension of PTC is an independent prognostic factor associated with BRAFV600E mutation status. However, conduct of further large scale studies with long term follow up is required before the BRAF mutation can be conclusively recommended as a prognostic biomarker.

Ectopic breast tissue can occur anywhere along the incompletely regressed mammary ridge. Among the various types of breast choristoma, ectopic breast tissue, which has only glandular tissue without a nipple or areola, is most commonly detected in axillary areas. However, ectopic breast cancer is often not detected until significant clinical symptoms have been revealed, or diagnosis is delayed. Furthermore, an examination of ectopic breast tissue tends to be omitted from a screening mammography. Especially, the microcalcifications of ectopic breast tissue are difficult to delineate on mammography. Herein, the authors report a case of ectopic breast carcinoma that showed clustered microcalcifications on screening mammography, and discuss the interpretation and implications of microcalcification in ectopic breast tissue.
