Rice bodies are commonly detected in adults with rheumatoid arthritis and rarely occur in children. An 11-year-old female adolescent who visited our hospital for evaluation of knee pain underwent a MRI scan, which revealed an intra-articular mass. Arthroscopic examination of the mass confirmed conglomerated rice bodies. We report a case of rice bodies that clinically presented as intra-articular masses.

The purpose of this study was to summarize the results of a survey for physicians with specialties other than radiology about imaging studies of patients referred from other institutions. The survey was promoted through individual contacts or social network service and physicians who voluntarily responded to the survey were the subjects of the study. The questionnaire consisted of 11 questions about basic information and referrals about medical imaging. A total of 160 physicians from 30 specialties participated in the survey and 95.6% of the respondents worked in tertiary care center or general hospital. Patients were frequently referred with outside medical images. The most frequently referred imaging modalities were computed tomography and magnetic resonance imaging. However, radiological reports from outside institutions were rarely referred. Most physicians thought that reinterpretation for outside imaging is necessary to acquire a secondary opinion. In conclusion, considering that outside radiological reports are frequently missing and there are high demands on reinterpretation for outside imaging, guidelines for referral of radiological reports with medical imaging, basic elements of radiological reports, and reinterpretation need to be developed.

Objectives : The fourth revision of Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) was performed to provide more proper guidelines for clinicians. In this study, we evaluated treatment strategies of elderly patients with bipolar disorders of KMAP-BP 2018. Methods : Sixty-one psychiatrists of the review committee with vast clinical experiences in treating bipolar disorders, completed the survey. An expert consensus was obtained, on pharmacological treatment strategies for elderly patients with bipolar disorder. The executive committee analyzed results, and discussed the results to produce the final algorithm. Results : In elderly patients with bipolar disorder, first-line treatment option for acute manic episode is monotherapy, with atypical antipsychotics or mood stabilizer, and a combination of mood stabilizer and atypical antipsychotics. First-line treatment option for acute depressive episode, was a combination of mood stabilizer and atypical antipsychotics, monotherapy with atypical antipsychotic or mood stabilizer, and atypical antipsychotics with lamotrigine. Conclusion : In KMAP-BP 2018, the recommendation for treatment option in elderly patients with bipolar disorder, was newly introduced. We expect this algorithm may provide valuable information, and facilitate treatment of elderly patients with bipolar disorder.

Background/Objectives: The efficacy of radiotherapy alone versus chemoradiotherapy has been studied in patients with T2N0M0 laryngeal squamous cell carcinoma. Materials & Methods: Thirty nine patients with newly diagnosed T2N0M0 laryngeal squamous cell carcinoma were treated with either radiotherapy(RT group, 66-70Gy) or chemoradiotherapy(CRT group, cisplatin based concurrent chemoradiation with or without 2 cycles induction chemotherapy including cisplatin, $5-FU{\pm}$ docetaxel / radiation therapy same with above mentioned). The mean follow-up was 73.5 months. Results: The overall survival (OS), disease specific survival (DSS), disease free survival (DFS), and larynx preservation survival (LPS) at 5 years were 70%, 79%, 67%, and 71%. The complete response rate was 82.4% in RT group, and was 95.5% in CRT group. OS (57% vs 80%), DSS (69% vs 86%), DFS (52% vs 77%), and LPS (63% vs 77%) at 5 years were higher in CRT group than RT group, but it was not statistically significant. In subsite analysis, CRT group tends to improve DFS, compared to RT group, in glottic cancer (p=0.06). The toxicities were tolerable and no fatal case was observed in both groups. Conclusion: Chemoradiotherapy is effective as primary therapy for T2 laryngeal squamous cell carcinoma and showed manageable treatment induced toxicity.

Objectives : The purpose of this study was to investigate the association between the insulin resistance and depressive mood, suicidal ideation, psychological stress, and quality of life in general Korean population. Methods : We selected 3,613 subjects from the third year's data of 6th Korean National Health and Nutritional Examination Survey. Insulin resistance was evaluated with Homeostatic Model Assessment of Insulin Resistance. Questionnaires on depressive mood, suicidal ideation and psychological stress were conducted. The quality of life was assessed with the EuroQol-5 dimension index. We used correlation and regression analysis for analysis. Results : The risk of depressive mood and suicidal ideation was significantly higher in the insulin resistance group than in the control group. The risk of psychological stress was significantly higher in the male group with insulin resistance. The EuroQol-5 dimension index showed a negative correlation with insulin resistance. After adjusting for age, sex and body mass index, increased risk of suicidal ideation was identified only. Conclusions : We confirmed that insulin resistance is associated to mental health problems related with depression in Korean adults.

A dermatophyte is a zoonotic infection that causes infection on the skin, hair, and nails and is transmitted through contact. The species of Microsporum, Trichophyton, and Epidermophyton are the major dermatophytes that infect humans. Tinea capitis is a dermatophyte infection in the scalp, and it may progress to kerion celsi, including severe redness, swelling, and pus formation. Kerion celsi is sometimes misdiagnosed as a bacterial infection or a tumor. Trichophyton verrucosum is a zoophilic dermatophyte that mainly causes infection in cattle. It can be spread to dairy farmers or ranchers who have frequent contact with infected cattle. We report a pediatric case who received scalp tumor excision and a split-thickness skin graft for extensive and severe inflammatory scalp tumors that occurred after contact with cattle with ringworm. Finally, the patient was diagnosed with kerion celsi caused by T. verrucosum infection. This was based on the patient's medical history, clinical manifestations, and histopathologic findings.

Xanthogranulomatous inflammation is a rare inflammatory reaction, characterized by lipid-laden macrophages, known as xanthomas, in histopathologic examination. Aggressive xanthogranulomatous inflammation often manifests as local infiltration but does not affect distant organs unless combined with rare systemic diseases. We report a case of focal xanthogranulomatous pyelonephritis (XGP) associated with severe xanthogranulomatous cholecystitis. Focal XGP was suspected in radiologic examination that showed a cystic lesion with an infiltrative margin, which were surgically resected and confirmed in pathologic examination. To our knowledge, this is the first report of focal xanthogranulomatous pyelonephritis associated with xanthogranulomatous cholecystitis. Moreover, we found peripheral hypointensity around the cystic lesion in the T2-weighted image, probably reflecting hemorrhage and fibrosis of the xanthogranulomatous inflammation.

Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.

Objective: We evaluated the clinical characteristics and prognoses of patients with septic shock who transferred to the emergency department (ED) in a tertiary referral center. Methods: This study was performed using a prospective, multi-center registry of septic shock, with the participation of 11 tertiary referral centers in the Korean Shock Society between October 2015 and February 2017. We classified the patients as a transferred group who transferred from other hospitals after meeting the inclusion criteria upon ED arrival and a non-transferred group who presented directly to the ED. Primary outcome was hospital mortality. We conducted multiple logistic regression analysis to assess variables related to in-hospital mortality. Results: A total of 2,098 patients were included, and we assigned 717 patients to the transferred group and 1,381 patients to the non-transferred group. The initial Sequential Organ Failure Assessment score was higher in the transferred group than the non-transferred group (6; interquartile range [IQR], 4-9 vs. 6; IQR, 4-8; P<0.001). Mechanical ventilator (29% vs. 21%, P<0.001) and renal replacement therapy (12% vs. 9%, P=0.034) within 24 hours after ED arrival were more frequently applied in the transferred group than the non-transferred group. Overall hospital mortality was 22% and there was no significant difference between transferred and non-transferred groups (23% vs. 22%, P=0.820). Multivariable analysis showed an odds ratio for in-hospital mortality of 1.00 (95% confidence interval, 0.78-1.28; P=0.999) for the transferred group compared with the non-transferred group. Conclusion: The transferred group showed higher severity and needed more organ support procedures than the non-transferred group. However, inter-hospital transfer did not affect in-hospital mortality.
