Antithrombin deficiency is a rare condition among the numerous conditions that can lead to a hypercoagulable state, and can manifest as deep vein thrombosis, portal or mesenteric venous thrombosis, pulmonary thromboembolism and cerebrovascular accidents. In this report, we present a case of acute renal infarction and multiple venous thrombosis in a 36-year-old man with a family history of thromboembolism. He presented with a sudden onset of pain in the right flank and was admitted to the emergency room for evaluation. On computed tomography and renal angiography, the diagnosis of acute renal infarction concurrent with portal, splenic and superior mesenteric venous thrombosis was made. Laboratory data revealed parallel decreases in activity and antigen concentration of antithrombin despite normal liver and renal functions. He was treated with intravenous heparin and fresh frozen plasma followed by concomitant warfarin therapy. Taken together, the etiology of acute renal infarction and multiple venous thrombosis was considered to be associated with type I inherited antithrombin deficiency.

Neuroleptic malignant syndrome (NMS) is a rare but potentially lethal outcome caused by sudden discontinuation or dose reduction of dopaminergic agents. We report an extremely rare case of NMS after deep brain stimulation (DBS) surgery in a cerebral palsy (CP) patient without the withdrawal of dopaminergic agents. A 19-year-old girl with CP was admitted for DBS due to medically refractory dystonia and rigidity. Dopaminergic agents were not stopped preoperatively. DBS was performed uneventfully under monitored anesthesia. Dopaminergic medication was continued during the postoperative period. She manifested spasticity and muscle rigidity, and was high fever resistant to anti-pyretic drugs at 2 h postoperative. At postoperative 20 h, she suffered cardiac arrest and expired, despite vigorous cardiopulmonary resuscitation. NMS should be considered for hyperthermia and severe spasticity in CP patients after DBS surgery, irrespective of continued dopaminergic medication.

Background: Non-alcoholic fatty liver disease (NAFLD) recently became a leading liver disease that threatens health worldwide. Low muscle strength, obesity, insulin resistance, and metabolic syndrome are recognized key factors for NAFLD. However, the impact of low muscle strength itself in different metabolic conditions has not been widely studied. Methods: A cross-sectional analysis was performed of a sample of 5,427 participants from the 2019 Korea National Health and Nutrition Examination Survey. Relative handgrip strength (rHGS, defined as handgrip strength/body mass index) was used to assess muscle strength. The cut-off values for a low rHGS were 1.405 for men and 0.850 for women. NAFLD was diagnosed if the Hepatic Steatosis Index was >36. Participants were stratified according to insulin resistance, metabolic syndrome, and central obesity for the subgroup analyses. Results: Complex sample multivariate logistic regression analysis revealed a significant association between low muscle strength and NAFLD after the adjustment for other confounders (odds ratio [OR], 1.92; P<0.001). In the insulin resistance, metabolic syndrome, and central obesity subgroups, a significant association between low muscle strength and NAFLD remained (OR, 1.66–4.19 depending on subgroup; all P<0.05), whereas it did not in the no central obesity group. Conclusion This study demonstrated that low muscle strength is correlated with a risk of NAFLD. This relationship was independent of insulin resistance and metabolic syndrome but was dependent on the presence of central obesity.

Medullary carcinoma of the thyroid gland is a malignant neuroendocrine tumor arising from calcitonin producing-parafollicular cells. The tumor is clinically divided into sporadic and familial form, constituting about 80% and 20%, respectively. Recently, we experienced a case of unilateral and solitary sporadic medullary carcinoma of the left thyroid gland. The patient was a 9 year-old female, who presented with a palpable mass on the anterior lateral neck of 8 months duration without any familial and personal history of neuroendocrine disease. The cytopathologic findings showed spindle cells and plasmacytoid cells in the background of colloid-like materal. The nuclei were eccentrically located, mildly hyperchromatic and pleomorphic, showing speckled chromatin pattern without nuclear inclusion or prominent nucleoli. The cytoplasm was abundant and had a pale granular cyanophilic appearance. No amyloid materal could be identified.

OBJECTIVE: To investigate the hemispheric contributions to prosody recognitions and interference effects of semantic processing on prosody for stroke patients by using the Korean language. METHODS: Ten right hemisphere damaged patients (RHD), nine left hemisphere damaged patients (LHD), and eleven healthy controls (HC) participated. In pure prosody recognition task, four semantically neutral sentences were selected and presented in both sad and happy prosodies. In interference task, participants listened to emotionally intoned sentences in which the semantic contents were congruent or incongruent with prosody. Participants were asked to rate the valence of prosody while ignoring the semantic contents, and thus, reaction time and accuracy were estimated. RESULTS: In pure prosody recognition task, RHD showed low accuracy as compared to HC (p=0.013), and the tendency of group response showed that RHD performed worse than HC and LHD with regards to accuracy and reaction time. In interference task, analysis of accuracy revealed a significant main effect of groups (p=0.04), and the tendency implied that RHD is less accurate as compared to LHD and HC. The RHD took longer reaction times than HC in congruent and incongruent items (p<0.001). CONCLUSION: Right hemispheric laterality to prosody processing of Korean language in stroke patients was observed. Interference effects of semantic contents to prosody processing were not observed, which suggested unique characteristics of prosody for Korean language. These results could be referred as preliminary data for future researches on Korean languages.

OBJECTIVE: This study was performed to evaluate the possibility of prolonged culture of human embryonic stem cells (hESC; SNUhES2) on human amniotic fluid cells (hAFC), which had been storaged after karyotyping. METHOD: The hAFC was prepared for feeder layer in the presence of Chang's medium and STO medium (90% DMEM, 10% FBS) at 37degrees C in a 5% CO2 in air atmosphere. Prior to use as a feeder layer, hAFC was mitotically inactivated by mitomycin C. The hESCs on hAFC were passaged mechanically every seven days with ES culture medium (80% DMEM/F12, 20% SR, bFGF). RESULTS: The hAFC feeder layer support the growth of undifferentiated state of SNUhES2 for at least 59 passages thus far. SNUhES2 colonies on hAFC feeder appeared slightly angular and flatter shape as compared with circular and thicker colonies observed with STO feeder layer and showed higher level with complete undifferentiation in seven days. Like hESC cultured on STO feeders, SNUhES2 grown on hAFC expressed normal karyotype, positive for alkaline phosphatase activity, high telomerase activity, Oct-4, SSEA-3, SSEA-4, Tra-1-60 and Tra-1-81 and formed embryoid bodies (EBs). CONCLUSION: The hAFC supports undifferentiated growth of hESC. Therefore, these results may help to provide a clinically practicable method for expansion of hESC for cell therapies.
