Anti-LGI1 (leucine-rich glioma inactivated-1) antibody encephalitis is one of autoimmune encephalitis. We report a 66-year-old man who presented with frequent, brief dystonic seizures which involve predominantly ipsilateral face and arm without cognitive impairment. Brain MRI showed normal finding. Serum and CSF tests revealed anti-LGI1 antibody. His symptom was not relieved by antiepileptic drugs, but completely controlled after immunotherapy. This case indicates that recognition of the brief, dystonic seizures should do tests for anti-LGI1 antibodies.

BACKGROUND AND OBJECTIVES: The role of endolymphatic sac decompression (ELSD) for the treatment of intractable Meniere disease (MD) has been debated. However, considering few treatment options for medically intractable MD with serviceable hearing or intractable bilateral MD, ELSD has shown reasonable treatment results without ablating inner ear function. The aims of this study are to review the role of ELSD in the treatment of MD and clinical course and long-term outcome after ELSD. MATERIALS AND METHODS: The ELSD was performed in 7 patients among 603 definite Meniere disease patients between May 2003 and December 2010. Patient's medical history and clinical courses after surgery were obtained by medical record review and telephone interview. RESULTS: Mean duration of follow up until receiving ELSD was 575 days since initial visit. Six patients showed complete control or substantial control of vertigo, but one patient suffered from sustained vertigo attacks even after ELSD, the vertigo was controlled after intratympanic gentamicin injection (ITGI) at 20 months after ELSD. Another patient had recurrence of vertigo after 30 months, which was successfully controlled by ITGI. The preoperatively mean monthly vertigo was 4.8 and it was significantly decreased to 1.5 after postoperatively 1 year, 0 after postoperatively 2 years (p<0.001). Hearing was preserved in 6 patients during the follow-up period. CONCLUSION: Most patients who were uncontrolled vertigo with 3 to 6 months medication showed significantly reduced vertigo and hearing preservation after ELSD. The ELSD seems to be a beneficial treatment option for intractable MD.

In this study, we compared the immune cell populations in rheumatoid arthritis (RA) synovial fluid, which shows lymphoid tissue-like structure, with those in tonsils, which are normal secondary lymphoid tissues. Firstly, we found that CD4-CD11b+ macrophages were the major population in RA synovial fluid and that B cells were the major population in tonsils. In addition, synovial fluid from patients with osteoarthritis, which is a degenerative joint disease, contained CD4+CD11b+ monocytes as the major immune cell population. Secondly, we categorized three groups based on the proportion of macrophages found in RA synovial fluid: (1) the macrophage-high group, which contained more than 80% macrophages; (2) the macrophage-intermediate group, which contained between 40% and 80% macrophages; and (3) the macrophage-low group, which contained less than 40% macrophages. In the macrophage-low group, more lymphoid tissue inducer (LTi)-like cells were detected, and the expression of OX40L and TRANCE in these cells was higher than that in the other groups. In addition, in this group, the suppressive function of regulatory T cells was downregulated. Finally, CXCL13 expression was higher in RA synovial fluid than in tonsils, but CCL21 expression was comparable in synovial fluid from all groups and in tonsils. These data demonstrate that increased lymphocyte infiltration in RA synovial fluid is correlated with an increase in LTi-like cells and the elevation of the chemokine expression.

BACKGROUND AND OBJECTIVES: This study aims to evaluate audiologic results and subjective satisfaction of bone anchored hearing aids (BAHA) patients. SUBJECTS AND METHOD: Preoperative air-conduction and bone-conduction thresholds, postoperative aided thresholds were measured for 14 patients. To evaluate patient satisfaction, two questionnaires derived from single sided deafness (SSD) questionnaire and Bern Benefit in SSD questionnaire were used. RESULTS: The mean age of patients, consisting of 8 males and 6 females, was 40.0+/-5.9 year. Ten patients (71%) received implantations for conductive or mixed hearing loss and 4 (29%) for SSD. The mean follow-up period was 27.8+/-5.6 months. The mean preoperative bone-conduction threshold of conductive or mixed hearing loss group was 21.4 dB and the mean air-conduction threshold was 65.4 dB. The mean bone-conduction threshold of SSD group was 60.0 dB and the mean air-conduction threshold was 105.9 dB. The postoperative aided threshold was significantly improved in conductive or mixed hearing loss group (p=0.005). The patients in the conductive or mixed hearing loss group showed more satisfaction with BAHA than those in the SSD group did, but the degree of satisfaction was not statistically significant (p=0.08 for questionnaire 1, p=0.12 for questionnaire 2). Patients with better preoperative bone-conduction threshold and patients with better preoperative speech discrimination score showed more satisfaction with BAHA in the questionnaire 1 (p=0.045, p=0.036). CONCLUSION: BAHA can be considered effective and beneficial for patients with conductive or mixed hearing loss and SSD. Further studies will be needed to choose the appropriate indications for BAHA, especially in SSD group in Korea.

Purpose:
Although smoking has a significant impact on mortality and morbidity of cancer patients, many patients continue to smoke post-diagnosis. The purpose of this study was to investigate prevalence and predictors of sustained smoking among male cancer survivors.
Materials and Methods:
The Korean National Health Insurance Service-National Health Screening Cohort database was used for this population-based, retrospective study. Study subjects were 15,141 men who were diagnosed with their first incident cancer between 2004 and 2011. Changes in smoking status before and after a cancer diagnosis were investigated. For patients who were current smokers pre-diagnosis, association between post-diagnosis sustained smoking and demographic, socioeconomic, and clinical variables were examined.
Results:
Of the 4,657 pre-diagnosis smokers, 2,255 (48%) had quit after cancer diagnosis, while 2,402 (51.6%) continued to smoke. In a multivariate logistic regression analysis, younger age at cancer diagnosis (adjusted odds ratio [aOR], 1.37; 95% confidence interval [CI], 1.21 to 1.55; p < 0.001), low socioeconomic status (aOR, 1.29; 95% CI, 1.15 to 1.45; p ≤ 0.001), pre-diagnosis heavy smoking (aOR, 1.24; 95% CI, 1.09 to 1.41; p=0.001), diagnosis of non-smoking– related cancer (aOR, 1.67; 95% CI, 1.42 to 1.96; p < 0.001), and high serum glucose level (aOR, 1.23; 95% CI, 1.03 to 1.46; p=0.019) were associated with sustained smoking after a cancer diagnosis.
Conclusion
Almost half of the male smokers continue to smoke after a cancer diagnosis. Targeted interventions for smoking cessation should be considered for patients with younger age, low socioeconomic status, heavy smoking history, non-smoking–related cancer, and high blood glucose levels.

Purpose:
To evaluate the role of postmastectomy radiation therapy (PMRT) in patients with node-negative breast cancer of 5cm or larger tumors undergoing mastectomy
Materials and Methods:
Medical records of 274 patients from 18 institutions treated with mastectomy between January 2000 and December 2016 were retrospectively reviewed. Among these, 202 patients underwent PMRT, while 72 did not. Two hundred and forty-one patients (88.0%) received systemic chemotherapy, and 172 (62.8%) received hormonal therapy. Patients receiving PMRT were younger, more likely to have progesterone receptor-positive tumors, and received adjuvant chemotherapy more frequently compared with those without PMRT (p <0.001, 0.018, and <0.001, respectively). Other characteristics were not significantly different between the two groups.
Results:
With a median follow-up of 95 months (range, 1-249), there were 9 locoregional recurrences, and 20 distant metastases. The 8-year locoregional recurrence-free survival rates were 98.0% with PMRT and 91.3% without PMRT (p=0.133), and the 8-year disease-free survival (DFS) rates were 91.8% with PMRT and 73.9% without PMRT (p=0.008). On multivariate analysis incorporating age, histologic grade, lymphovascular invasion, hormonal therapy, chemotherapy, and PMRT, the absence of lymphovascular invasion and the receipt of PMRT were associated with improved DFS (p=0.025 and 0.009, respectively).
Conclusion
Locoregional recurrence rate was very low in node-negative breast cancer of 5cm or larger tumors treated with mastectomy regardless of the receipt of PMRT. However, PMRT was significantly associated with improved DFS. Further investigation is needed to confirm these findings.

This paper describes a community effort to improve earlier versions of the full-text corpus of Genomics & Informatics by semi-automatically detecting and correcting PDF-to-text conversion errors and optical character recognition errors during the first hackathon of Genomics & Informatics Annotation Hackathon (GIAH) event. Extracting text from multi-column biomedical documents such as Genomics & Informatics is known to be notoriously difficult. The hackathon was piloted as part of a coding competition of the ELTEC College of Engineering at Ewha Womans University in order to enable researchers and students to create or annotate their own versions of the Genomics & Informatics corpus, to gain and create knowledge about corpus linguistics, and simultaneously to acquire tangible and transferable skills. The proposed projects during the hackathon harness an internal database containing different versions of the corpus and annotations.
