PURPOSE: Cervical lymphadenectomy is frequently performed in patients with lateral cervical lymph node metastasis to improve regional control of disease. However, there is controversy regarding appropriate levels of the neck that need to be dissected. In particular, the routine dissection of level V remains an annoying and time consuming procedure due to the injury of the spinal accessory nerve. METHODS: To identify clinical and pathological predictors of cervical node metastases to level V in papillary thyroid carcinoma, we analyzed 42 patients who underwent modified radical neck dissection (MRND), which were separately performed by each strict anatomical level. Five patients underwent both MRND, 29 patients received total thyroidectomy with central neck node dissection and MRND at the time of initial operation. Thirteen patients underwent MRND later when lateral neck metastases were found at the follow-up after total thyroidectomy with central neck node dissection. RESULTS: In our series, 11.9% of neck specimens harbored metastatic thyroid carcinoma at level V. The metastatic rate of level II, III, and IV was 54.7%, 85.7%, and 64.2%, respectively. The presence of level V metastases was not significantly associated with level II, III metastases, age, sex, and histopathologic findings. But, it seemed to be associated with level IV metastases if the proportion of metastasis of level IV exceeded 50%. CONCLUSION: Cervical node metastasis seems to be associated with level IV metastases if the proportion of metastasis of level IV exceeds 50%.

OBJECTIVES: The aim of this study was to clarify the role of alcohol use disorders and acute alcohol consumption in suicide attempts by gender. METHODS: Data of 1,152 suicide attempters(487 males and 742 females) who had visited an emergency center was gathered. Suicide attempts were categorized into three groups according to alcohol use: an alcohol use disorder group(AUD), an acute alcohol use group(AAU), and a no-alcohol use group(NAU). The intent and lethality of suicide attempts were evaluated by Suicidal Intents Scale and Risk-Rescue Rating Scale. RESULTS: For Suicidal Intents Scale score, the male AUD group revealed a significantly lower mean score than the male AAU one. However, there were no statistically significant differences for female subjects across subgroups. With regard to the Risk-Rescue Rating Scale score, there were no significant differences for males, while the AUD group showed both the lowest highest rescue scores and lowest risk-rescue scores within female groups. CONCLUSIONS: AUD in females was more likely regarding impulsive suicide attempts with high rescue chances. Consuming alcohol might have different effect on suicide attempts by gender and our study shows that alcohol use is an important risk factor according to gender, particularly with regard to female suicide attempts.
