Clinicopathological features of rare BRAF mutations in Korean thyroid cancer patients.
The most common BRAF mutation in thyroid cancer is c.1799T>A (p. Val600Glu), and other BRAF mutations are rarely reported. We investigated the clinicopathological features of thyroid cancer with rare BRAF mutations. ⋯ None of the patients with the c.1801A>G mutation showed extrathyroidal extension or lymph node metastasis. The prevalence of rare BRAF mutations was 0.76% of all BRAF-positive thyroid cancers, and the rare mutations were associated with less aggressive pathologic features. Although BRAF mutations are detected exclusively in papillary carcinoma, they are also found in medullary carcinoma and follicular carcinoma. [Corrected]

Observational StudyThe influence of depression, anxiety and somatization on the clinical symptoms and treatment response in patients with symptoms of lower urinary tract symptoms suggestive of benign prostatic hyperplasia.
This is the first study to investigate the influence of depression, anxiety and somatization on the treatment response for lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH). The LUTS/BPH patients were evaluated with the Korean versions of the International Prostate Symptom Score (IPSS), the Patient Health Questionnaire-9 (PHQ-9), the 7-item Generalized Anxiety Disorder Scale (GAD-7) and the PHQ-15. The primary endpoint was a responder rate defined by the total score of IPSS (≤ 7) at the end of treatment. ⋯ Our exploratory results suggest that depression, anxiety and somatization may have some influences on the clinical manifestation of LUTS/BPH. Further, anxious patients had a lower response to treatment in patients with LUTS/BPH. Despite of limitations, the present study demonstrates that clinicians may need careful evaluation of psychiatric symptoms for proper management of patients with LUTS/BPH.

Writing a good quality scientific article takes experience and skill. I propose 'Ten Tips' that may help to improve the quality of manuscripts for scholarly journals. It is advisable to draft first version of manuscript and revise it repeatedly for consistency and accuracy of the writing. During the drafting and revising the following tips can be considered: 1) focus on design to have proper content, conclusion, points compliant with scope of the target journal, appropriate authors and contributors list, and relevant references from widely visible sources; 2) format the manuscript in accordance with instructions to authors of the target journal; 3) ensure consistency and logical flow of ideas and scientific facts; 4) provide scientific confidence; 5) make your story interesting for your readers; 6) write up short, simple and attractive sentences; 7) bear in mind that properly composed and reflective titles increase chances of attracting more readers; 8) do not forget that well-structured and readable abstracts improve citability of your publications; 9) when revising adhere to the rule of 'First and Last' - open your text with topic paragraph and close it with resolution paragraph; 10) use connecting words linking sentences within a paragraph by repeating relevant keywords.

Susceptibility of Escherichia coli from community-acquired urinary tract infection to fosfomycin, nitrofurantoin, and temocillin in Korea.
With increase of multi-drug resistant Escherichia coli in community-acquired urinary tract infections (CA-UTI), other treatment option with a therapeutic efficacy and a low antibiotic selective pressure is necessary. In this study, we evaluated in vitro susceptibility of E. coli isolates from CA-UTI to fosfomycin (FM), nitrofurantoin (NI), temocillin (TMO) as well as trimethoprim-sulfamethoxazole (SMX), ciprofloxacin (CIP) and cefepime (FEP). The minimal inhibitory concentrations were determined by E-test or agar dilution method according to the Clinical and Laboratory Standards Institute guidelines, using 346 E. coli collected in 12 Korean hospitals from March 2010 to February 2011. ⋯ Conversely, resistance rates of CIP and SMX were 22% (76/346) and 29.2% (101/349), respectively. FEP still retained an activity of 98.5%. In Korea, NI and TMO in addition to FM are a good therapeutic option for uncomplicated CA-UTI, especially for lower UTI.

Trends and risk factors of the epidemic of charcoal burning suicide in a recent decade among Korean people.
The aims of this study were to analyze annual trends of charcoal burning (CB) suicide, 2000 to 2011, and to examine the risk factors of CB suicide in Korea. Data on suicides (n=138,938) were obtained from the Statistics Korea. ⋯ Of significant risk factors of CB suicide, the presence of the media report of Ahn's suicide was the greatest risk factor (adjusted odds ratio, 11.69; 95% CI, 10.30-13.23) of the initial phase of the continuing CB suicides since 2008. Korean Government should urgently consider effective measures against CB suicide, including enforced media regulations on reporting such suicides.
