To clinically and radiologically report a traumatic spinal epidural hematoma (SEH) that completely resolved, without surgical treatment. A 17-year-old woman presented with back pain, lower motor weakness, and sensory change after trauma to the lower back area. Neurologic examination revealed paraparesis (grade 3/5) and radiating pain in both legs at the L5 dermatome. Magnetic resonance imaging (MRI) of the lumbar spine showed a spaceSEH-occupying lesion in the ventral spinal epidural space at

However, the patient's neurologic symptoms began to improve (grade 4+/5) at 2 hr after the onset of paraparesis. Surgical intervention was delayed, and the patient was treated conservatively with close neurologic monitoring. Two days after the onset of symptoms, the patient's neurologic symptoms recovered completely. The follow-up MRI at 3 days after the event showed complete resolution of the epidural hematoma. A SEH can occur after blunt trauma to the spine. This case illustrates that immediate surgical intervention may not always be necessary in some patients with traumatic SEH. Conservative management may be a possible option for patients presenting with neurologic dysfunction if neurological symptoms recover rapidly.

2016 Medicine  
Little is known about prognostic factors in epithelioid hemangioendothelioma (EHE). We aimed to identify prognostic factors among various clinicopathologic and imaging features of thoracic EHEs. Forty-two patients (male:female = 20:22; median age, 49 years) of EHEs with (n = 19) and without (n = 23) thoracic involvement were included. We reviewed electronic medical records for clinical information and computed tomography (CT) features for thoracic involvement. Differences in demographics and
more » ... vival outcomes of patients with and without thoracic involvement were assessed. We also estimated overall survival. The most common pattern of thoracic involvement was multiple pulmonary nodules (n = 10), followed by parenchymal tumor with pleural invasion (n= 4), reticulonodular opacities (n = 3), and diffuse pleural thickening (n = 2). No significant difference in survival was found between the thoracic EHE group and nonthoracic EHE group (P = 0.68). Among 4 different thoracic involvement types, the lung multinodular pattern tended to demonstrate longer median survival (8.5 months) than other patterns, whereas the shortest median survival (1 month) was observed for the nodule/mass with pleural involvement pattern (P = 0.038). CT manifestations of thoracic EHEs are classified into 4 patterns, of which lung multinodular pattern is associated with longer survival. Survival is not different between patients with and without thoracic involvement. Abbreviations: 18-FDG PET/CT = fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography, EHE = epithelioid hemangioendothelioma, OS = overall survival, SUVmax = maximum standardized uptake values.

AbstractThis study aimed to investigate the effect of intraoperative fluid volume on the postoperative ileus (POI) recovery period. A retrospective review of the Korean robot-assisted radical cystectomy database identified 718 patients who underwent robot-assisted radical cystectomy (RARC). Regression analyses were performed to identify the associations between the amount of intraoperative fluid administration (crystalloid/colloid/total), POI period (time to flatus/bowel movements), and length

An increasing volume of the administered crystalloid/total fluid was associated with prolonged POI (crystalloid R2 = 0.0725 and P < 0.0001; total amount R2 = 0.0812 and P < 0.0001), and the total fluid volume was positively associated with the LOS (R2 = 0.099 and P < 0.0001). The crystalloid amount was a risk factor for prolonged POI (P < 0.001; odds ratio, 1.361; 95% confidence interval, 1.133–1.641; P < 0.001). In the context of RARC, increased intravenous fluids are associated with prolonged POI and longer LOS.

Objective. To estimate the prevalence of non-adherence to rheumatoid arthritis (RA) medication and identify the associated factors for non-adherence in RA patients. Methods. Among the KORean Observational study Network for Arthritis 3,523 patients who completed a questionnaire about the adherence to RA medication were analyzed. The patients were divided into two groups: 1) adherent group, patients who skipped medication ≤5 days within the past 2 months; and 2) non-adherent group, patients who

The non-adherent group had 339 patients (9.6%). The common causes of non-adherence were forgetfulness (45.8%), absence of RA symptoms (24.7%), and discomfort with RA medication (13.1%). Younger age (odds ratio [OR] 1.02, p<0.01) and higher income (OR 1.70, p<0.01) were associated with an increased risk of non-adherence. Whereas higher functional disability (OR 0.68, p<0.01) and oral corticosteroid use (OR 0.73, p=0.02) were associated with a decreased risk of non-adherence. The associated factors differed according to cause of non-adherence. Having adverse events (OR 2.65, p=0.02) was associated with the risk of non-adherence due to discomfort with RA medication while a higher level of education (OR 2.37, p=0.03) was associated with the risk of non-adherence due to an absence of RA symptoms. Conclusion. The 9.6% of Korean RA patients were non-adherent to RA medication. The associated factors differed according to the cause of non-adherence. Therefore, an individualized approach will be needed to improve the adherence to RA medication. (J Rheum Dis 2018;25:47-57)

EC-18 (monoacetyldiacylglyceride) stimulates T cell production of IL-2, IL-4, IL-12, IFN-γ , and GM-CSF in vitro. To study the effects of these cytokines stimulated by EC-18 on cancer cells, we applied hamster biliary cancer model, a difficult cancer to treat. Cancer (KIGB-5) cells were given intravenously to produce hematogenous metastatic lung lesions which were treated with EC-18 at 10, 25, and 50 mg/kg/day respectively. The fourth group was untreated control. At 4th, 8th, and 12th week the

EC-18 treated groups showed only a few microscopic lung lesions and no evidence of metastatic lesion with highest dose whereas widespread gross lung lesions were observed in untreated control. To investigate whether the anti-tumor effect of EC-18 is associated with suppression of tumor cell Toll-like receptor 4 (TLR-4) expression in addition to stimulation of the immune cells, KIGB-5 cells were exposed to LPS with or without EC-18. TLR-4 mRNA and protein expression, measured by reverse transcriptase PCR (RT-PCR), real-time quantitative PCR and western blot analysis, showed suppression of TLR-4 expression in KIGB-5 cells treated with EC-18 compared with control. In conclusion, EC-18 has a significant anti-tumor effect in this experimental model of biliary cancer suggesting potential for clinical application to this difficult cancer.

Sang-Mun Lee, Kyoung-Don Lee, Heung-Ki Min, Tae-Sung Noh, Sung-Tae Kim
2012 The Journal of Korea Robotics Society  
A humanoid robot hand with one thumb and two fingers has been developed. Each finger has the specially designed compact joints, called "MEC Joint", which convert the rotation of a motor to the swing motion of a pendulum. The robot hand with the MEC Joints is compact and relatively light but strong enough to grasp objects in the same manner as human being does in daily activities. In this paper the kinematic model and the torque characteristics of the MEC Joint are presented and compared with

2006 Alzheimer's & Dementia  
Behavioral and psychological symptoms (BPSD) are common in dementia. These may be helpful for clinical differentiation between Alzheimer's disease (AD) and vascular dementia (VD). Most previous studies have reported the prevalence and severity of BPSD regardless of severity of progression. However, we evaluated the differences of BPSD by grading dementia progression and including severe cases only. Methods: 141 dementia outpatients from clinics of Busan-Gyeongnam Dementia Association in Korea

All patients were administered the Korean version of the Neuropsychiatric Inventory (K-NPI), the expanded version of Korean Clinical Dementia Rating Scale (CDR), and the Korean version of Mini-Mental State Examination (K-MMSE). Results: There were 95 patients with AD and 46 patients with VD. AD patients revealed higher frequency of manifested BPSD symptoms and most of subscales showed higher composite scores also. But apathy was more severely and frequently manifested in VD. AD patients had more frequent night-time behavior and aberrant motor symptoms above 3 point in CDR 0.5 and VD patients had more frequent apathy symptom above 3 point in CDR 1. Conclusions: These results suggest that generally AD patients revealed more frequent and severe BPSDs than VD patients. Apathy was a more dominant symptom in VD. It seemed that some of the symptoms were valuable clues for the differential diagnosis even though a better designed study was required.
