The functionally generated path (FGP) technique, first described by Meyer in 1933, is a method in the oral cavity to use the movement pathway formed by the opposing cusps within the border movement of the mandible. Using this method, an appropriate occlusal shape can be given to the patient. In this case, the FGP technique was selected to provide a bilateral balanced occlusion when restoring the edentulous maxilla that opposes the natural mandibular teeth with irregular arrangement with overdentures. In addition, in order to precisely form the occlusal surface of the posterior region with the FGP technique and to reduce the attrition of denture teeth, zirconia denture teeth, not conventional resin artificial teeth, were individually manufactured. After treatment with these materials and methods, satisfactory results were obtained for both the operator and the patient.

Background:
The aim of the present study was to evaluate the prognostic significance of B-cell lymphocyte kinase (BLK) expression for survival outcomes in diffuse large B-cell lymphoma (DLBCL) patients treated with R-CHOP.
Methods:
We retrospectively analyzed the medical records of 89 patients from two tertiary referral hospitals. The expression of BLK, SYK, and CDK1 were evaluated in a semiquantitative method using an H-score, and the proportions of BCL2 and C-MYC were evaluated.
Results:
A total of 89 patients received R-CHOP chemotherapy as a first-line chemotherapy. The expression rates of BLK in tumor cells was 39.2% (n = 34). BLK expression status was not significantly associated with clinical variables; however, BLK expression in tumor cells was significantly associated with the expression of both C-MYC and BCL2 (p = .003). With a median follow-up of 60.4 months, patients with BLK expression had significantly lower 5-year progression-free survival (PFS) and overall survival rates (49.8% and 60.9%, respectively) than patients without BLK expression (77.3% and 86.7%, respectively). In multivariate analysis for PFS, BLK positivity was an independent poor prognostic factor (hazard ratio, 2.208; p = .040).
Conclusions
Here, we describe the clinicopathological features and survival outcome according to expression of BLK in DLBCL. Approximately 39% of DLBCL patients showed BLK positivity, which was associated as a predictive marker for poor prognosis in patients who received R-CHOP chemotherapy.

PURPOSE: This study shows the change in emergency room use behavior by homeless patients after implementation of the ‘Seoul Type Citizen Sympathy Emergency Room Project’ in July 2015. METHODS: A retrospective study was conducted in a public hospital between January 2014 and December 2014 and January 2016 and December 2016. Homeless patients who visited the emergency room in 2014 and 2016 were compared based on age, gender, mode of insurance, admission, revisit within 48 hours, length of stay (LOS) in the emergency department (ED), total cost, and major diagnostic category. RESULTS: A total of 3,642 homeless patients were enrolled during the study period, of which 1,876 visited in 2014 and 1,766 in 2016. Fewer homeless patients in 2016 revisited within 48 hours (p=0.046). Homeless in 2016 had a shorter ED LOS (p < 0.001) and lower total cost (p=0.040). More homeless patients who visited due to alcohol revisited within 48 hours in 2016 (p=0.036). Moreover, these patients did not have a different ED LOS (p=0.060) or total cost (p=0.475). Medicaid homeless patients were less connected compared health insurance by screening, brief intervention, referral to treatment program. CONCLUSION: Comparison of homeless patients who visited the emergency room in 2014 and 2016 revealed fewer total homeless patients in 2016, as well as less revisits within 48 hours, shorter ED LOS and lower total cost. These findings indicate that the ‘Seoul Type Citizen Sympathy Emergency Room Project’ was effective in the emergency room, but improvements for alcohol and medicaid homeless patients are needed.

PURPOSE: This study aimed to explore the association between increased level of ambient particulate matter and emergency room visits for chronic obstructive pulmonary disease (COPD) exacerbations. METHODS: A retrospective study was conducted. We enrolled patients who lived in Seoul, Korea and were diagnosed with COPD in the emergency room between January 2012 and December 2014. Meteorological factors [daily highest temperature, lowest temperature, mean temperature, diurnal temperature, rainfall, relative humidity, amount of sunshine and particulate matter less than 10 µm (PM 10)] between December 2011 and December 2014 in Seoul were acquired from the Korea Meteorological Administration. We used a multiple Poisson regression model with daily patient's number of COPD as a response variable and meteorological factors as explanatory variable. Variable selection was done via an Elastic net. RESULTS: There was a total of 1,179 emergency visits for acute exacerbations of COPD patients. PM10 (before 4, 10, 11, 15, 16, 17, 22, 24, 27, 28 day), rainfall (before 1, 6, 8, 16, 18 day), relative humidity (before 2, 8), and daily temperature difference (5, 10, 15 day) had a relationship and a lag effect with COPD exacerbations. CONCLUSION: This study showed that an increased concentration of PM10 was associated with COPD exacerbations. A future study that reinforces the limitation of this study is necessary to get a helpful index for an adequate response of medical institution and efficient placement of medical personnel.

The purpose of this study was to investigate the immunomodulatory activity of ice plant (Mesembryanthemum crystallinum) extract (IPE) in vitro and in vivo. Raji (a human B cell line) and Jurkat (a human T cell line) cells were treated with various doses of IPE and cell proliferation was measured by WST assay. Results showed that IPE promoted the proliferation of both Raji and Jurkat cells in a dose-dependent manner. IPE also enhanced IL-6 and TNF-α production in macrophages in the presence of lipopolysaccharide (LPS), although IPE alone did not induce cytokine production. Moreover, IPE treatment upregulated iNOS gene expression in macrophages in a time- and dose-dependent manner and led to the production of nitric oxide in macrophages in the presence of IFNγ. In vivo studies revealed that oral administration of IPE for 2 weeks increased the differentiation of CD4+, CD8+, and CD19+ cells in splenocytes. These findings suggested that IPE has immunomodulatory effects and could be developed as an immunomodulatory supplement.

BACKGROUND: Thyroid incidentalomas detected by 2-deoxy-2-18F-fluoro-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) have been reported in 1% to 4% of the population, with a risk of malignancy of 27.8% to 74%. We performed a retrospective review of FDG-avid thyroid incidentalomas in cancer screening subjects and patients with nonthyroid cancer. The risk of malignancy in thyroid incidentaloma and its association with the maximal standardized uptake value (SUVmax) in 18F-FDG PET/CT were evaluated to define the predictor variables in assessing risk of malignancy. METHODS: A total of 2,584 subjects underwent 18F-FDG PET/CT for metastatic evaluation or cancer screening from January 2005 to January 2010. Among them, 36 subjects with FDG-avid thyroid incidentalomas underwent further diagnostic evaluation (thyroid ultrasonography-guided fine needle aspiration cytology [FNAC] or surgical resection). We retrospectively reviewed the database of these subjects. RESULTS: Of the 2,584 subjects who underwent 18F-FDG PET/CT (319 for cancer screening and 2,265 for metastatic evaluation), 52 (2.0%) were identified as having FDG-avid thyroid incidentaloma and cytologic diagnosis was obtained by FNAC in 36 subjects. Of the subjects, 15 were proven to have malignant disease: 13 by FNAC and two by surgical resection. The positive predictive value of malignancy in FDG-avid thyroid incidentaloma was 41.7%. Median SUVmax was higher in malignancy than in benign lesions (4.7 [interquartile range (IQR), 3.4 to 6.0] vs. 2.8 [IQR, 2.6 to 4.0], P=0.001). CONCLUSION: Thyroid incidentalomas found on 18F-FDG PET/CT have a high risk of malignancy, with a positive predictive value of 41.7%. FDG-avid thyroid incidentalomas with higher SUVmax tended to be malignant.

Compartment syndrome is rarely associated with non-traumatic rhabdomyolysis. We report the case of a 23-year-old man who developed compartment syndrome associated with rhabdomyolysis caused by prolonged immobilization after antidepressive drug overdose. Elevation of serum creatine phosphokinase and myoglobinuria indicated rhabdomyolysis. Painful swelling of the right buttock and thigh and right lower limb paralysis with sensory and motor deficit were suggestive of gluteal and thigh compartment syndrome with the complication of sciatic nerve injury. The patient received an immediate fasciotomy, medical treatment and rehabilitation. At five months after initial treatment, the patient could walk independently with nearly full recovery of his right lower limb function.

Kimura's Disease is a very rare, chronic inflammatory disorder with an unknown etiology, and this illness is primarily seen in young Asian males. The typical clinical features consist of painless subcutaneous masses in the head or neck region, and especially in the salivary gland and submandibular region. It is often accompanied with a regional lymphadenopathy, peripheral blood eosinophilia and elevated serum IgE levels. Histologically, it is characterized by prominent germinal centers in the involved lymph nodes, together with eosinophilic infiltration in these lymph nodes. The treatment modalities for this disease are steroid therapy, radiation therapy and surgical excision. Its clinical course is of a benign nature. We report here on a case of a 28 year old man who had a soft tissue mass in his left arm. We excised this mass and the microscopy confirmed that he suffered from Kimura's disease on microscopic examination in his left distal arm.

Endovascular treatment of ethmoidal dural arteriovenous fistula (DAVF) has not been widely performed because of the technical difficulty of the procedure and the potential risk of central retinal artery occlusion. We report the case of a patient who underwent Onyx embolization through the ophthalmic artery in bilateral ethmoidal DAVF; to our best knowledge this is the first report.
