BACKGROUND: The aging of the patient population is one of rhe most important factirs influencing health care delivery. Currently 5% of the Korean population is elderly, defined as older than 65years of age, with this group projected to increase to 13.1% by the year 2021. Cardiovascular disease is the leading cause of death and of disability in the elderly age group. mong them, coronary heart disease is the most importane. METHOD: Study population composed of 216 patients who were admittied to the hospital with first acute myocardial infarction and they were divided into two groups according to the age(older than 65 years of age vs younger). Clonical features, risk factors of coronary heart disease, in-hospital outcome and complication were compared in elderly patients and others group. Results : 1) The risk factors of coronary heart disease is similar to younger patients but pattern of chest pain is less typical than younger patients. 2) Clinical presentation of elderly patients is similar to younger patients except Killip class on admission.(1.66vs 1.91,P=0.04) 3) In-hospital mortality of elderly patients in higher than younger patients. In addition to an increased incidence of death, recurrent ischemia, stroke, AV block, ventricular arrythmia, pulmonary edema occured more frequently with advanced age. 4) Especially in the thrombolytic therapy group, in-hospital death, reinfarction and recurrent ischemia is higher than primary PTCA group in elderly patients. CONCLUSIONS: Diagnosis of acute chest pain is difficult in elderly patients and in-hospital mortality and morbidity is higher than in younger patients. Thus more accurate diagnosis and discriminative therapeutic modality is needed.

Many studies have reported structural or functional brain changes in patients with alcohol-dependence (ADPs). However, there has been an insufficient number of studies that were able to identify functional changes along with structural abnormalities in ADPs. Since neuronal cell death can lead to abnormal brain function, a multimodal approach combined with structural and functional studies is necessary to understand definitive neural mechanisms. Here, we explored regional difference in cortical thickness and their impact on functional connection along with clinical relevance. Fifteen male ADPs who have been diagnosed by the Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) underwent highresolution T1 and resting-state functional magnetic resonance imaging (MRI) scans together with 15 male healthy controls (HCs). The acquired MRI data were post-processed using the Computational Anatomy Toolbox (CAT 12) and CONN-fMRI functional connectivity (FC) toolbox with Statistical Parametric Mapping (SPM 12). When compared with male HCs, the male ADPs showed significantly reduced cortical thickness in the left postcentral gyrus (PoCG), an area responsible for altered resting-state FC patterns in male ADPs. Statistically higher FCs in PoCG-cerebellum (Cb) and lower FCs in PoCG-supplementary motor area (SMA) were observed in male ADPs. In particular, the FCs with PoCG-Cb positively correlated with alcohol use disorders identification test (AUDIT) scores in male ADPs. Our findings suggest that the association of brain structural abnormalities and FC changes could be a characteristic difference in male ADPs. These findings can be useful in understanding the neural mechanisms associated with anatomical, functional and clinical features of individuals with alcoholism

BACKGROUND: EEG shows a sequence of progressive changes in status epilepticus (SE). Timely antiepileptic drug treatment is an important factor for the prognosis of SE. Here we investigated the effect of treatment according to EEG staging in a lithium-pilocarpine SE rat model. METHODS: By analyzing the on-going EEG of SE, we injected propofol (PF) or propofol and valproate (PF+VA) on each defined EEG stage [early period, merging stage; middle period, continuous stage; late period, early periodic epileptiform discharges stage (ePED)]. We measured the duration of each stage after the treatment and the number of principal cells at three hippocampal areas (CA1, CA3, dentate gyrus] after SE. RESULTS: Both PF- and PF+VA-treated groups showed lower mortality rate in the merging stage-treated subgroup than in ePED-treated subgroup. Seizure duration was significantly shortened in the merging stage of both PF- (p<0.005) and PF+VA-treated groups than in untreated group (p<0.002). The durations of the continuous stage and ePED were shortened in the merging stage-treated subgroup, but ePED duration did not decrease in ePED-treated subgroup. The shortening of the continuous stage and ePED was more prominent in the PF+VA-treated group than in PF-treated group. Neuronal loss in both PF- and PF+VA-treated groups was so severe that CA1 and CA3 neuronal loss was decreased more markedly in the ePED-treated group than in the merging stage-treated group (p<0.01). CONCLUSIONS: Early therapy based on the defined EEG staging might be an effective option for shortening duration of SE and decreasing neuronal damage at the hippocampus. Early combination therapy adopting PF+VA requires further investigation for new treatment option.

PURPOSE: To investigate the association between necrotizing enterocolitis (NEC) and red blood cell transfusions in very low birth weight (VLBW) preterm infants. METHODS: We studied were 180 VLBW preterm infants who were admitted to the neonatal intensive care unit of CHA Gangnam Hospital from January of 2006 to December of 2009. The subjects were divided into 2 groups: an NEC group (greater than stage II on the modified Bell's criteria) and a control group (less than stage II on the modified Bell's critieria). We defined red blood cell transfusion before NEC diagnosis as the frequency of transfusion until NEC diagnosis (mean day at NEC diagnosis, day 18) in the NEC group and the frequency of transfusion until 18 days after birth in the control group. RESULTS: Of the 180 subjects, 18 (10%) belonged to the NEC group, and 14 (78%) of these 18 patients had a history of transfusion before NEC diagnosis. The NEC group received 3.1+/-2.9 transfusions, and the control group received 1.0+/-1.1 transfusions before the NEC diagnosis (P=0.005). In a multivariate logistic regression corrected for gestational age, Apgar score at 1 minute, the presence of respiratory distress syndrome, patent ductus arteriosus, premature rupture of membrane, disseminated intravascular coagulopathy and death were confounding factors. The risk of NEC increased 1.63 times (95% confidence interval, 1.145 to 2.305; P=0.007) with transfusion before the NEC diagnosis. CONCLUSION: The risk for NEC increased significantly with increased transfusion frequency before the NEC diagnosis.

The malignant potential of a tumor is related to its ability to dissociate invasion and seed other sites-metastasis. In either instance, the tumor cells are confronted with a barrier signif icantly composed of type IV collagen. This type IV collagen is a major structural protein of basement membranes. Using immunohistochemical method to detect type IV collagen, intensity of stain and continuity of basement membrane at the tumor-stromal border was studied in surgical specimens from 47 colorectal carcinomas at the Pusan Paik-Hospital. Immunoreactivity was evaluated semi-quantitatively as three categories; Type-1, thick or normal basement membrane with or without minimal discontinuity; Type-2, thin basement membrane with or without moderate discontinuity; Type-3, fragmented or absent basement membrane. Also, in each case the tumor morphologic features were identified. The histologic type, differentiated grade, desmoplastic response, lymphatic and vascular invasion, lymph node involvement, tumor size and modified Dukes' stage were estabilished. Type-1 immunoreactivity was significantly observed in well-differentiated, negative lymph node, Dukes' stage B1/B2 tumors, and Type-3 was in poorly differentiated, positive lymph node, Dukes' stage C2/D. The expres sion of collagen IV in basement membrane was statistically significant correlated with differentiated grade, lymph node metastasis and modified Dukes' stage. By contrast, no statistically significant correlation was found between paucity of type IV collagen and the other parameters. The result suggest that expression of type IV collagen in basement membrane may be a useful prognostic marker, and may play a part in the invasive and metastatic process of colorectal carcinomas.

OBJECTIVE: We investigated plantar nerve injuries associated with calcaneal fracture and severity of disability. METHOD: From July, 2001 to June, 2002, twelve patients who had calcaneal fractures with persistent foot pain and paresthesia were included in our study. We examined electromyography for medial and lateral plantar nerve, inferior calcaneal nerve, also evaluated types of calcaneal fracture and severity of pain and disability with nerve injury. RESULTS: The intraarticular types were 13 cases, extraarticular type was 1 case and communited types were 2 cases. In the electromyographic findings, the 9 cases were diagnosed asneuropathy. In a cases with neuropathy, 8 persons complained over moderate degree of pain and all persons complained over moderate degree of walking disability. However one of three persons without neuropathy complained over moderate degree of walking disability. So disability tended to be more severe in cases with neuropathy. CONCLUSION: We think that neuropathy associated with calcaneal fracture is a cause of aggravation of pain and walking disability, and electromyography for nerves of foot will be needed in the calcaneal fracture.

OBJECTIVE: To evaluate the correlation of electrodiagnostic severity, severity of symptom, and clinical severity in carpal tunnel syndrome (CTS). METHOD: The sixty eight patients with documented CTS in outpatient clinic from January, 2000 to June, 2001 were included (9 male, 59 female, averaged age 50.0+/-8.8 years). We evaluated the severity of symptom, functional status of ADL with the Levine' questionnaire, and clinical severity with 3 kinds of examination (thenar atrophy, sensory change, and Phalen's test). The electrodiagnostic severity was classified according to Stevens' classification and compared with the severity of symptom, functional status, and clinical severity. RESULTS: The electrodiagnostic severity was classified into three degrees. Five patients (7.4%) were classified into mild degree, 32 patients (47.1%) moderate degree, 31 patients (45.6%) severe degree. The average of severity of symptom scores were 28.4+/-8.5, 31.8+/-7.4, and 31.8+/-9.1 respectively, and there was no significant difference (p>0.05) between the groups. Functional status scales were 14.2+/-6.7, 15.6+/-5.4 and 18.9+/-7.0 respectively and no significant difference (p=0.07) but there was a tendency that the severer was electrodiagnostic severity, the more decreased functional status scale. The clinical severity showed a significant correlation with the electrodiagnostic severity (p<0.05). CONCLUSION: The electrodiagnostic severity has a significant correlation with the clinical severity, but not with the severity of symptom, the functional status in CTS.

The coronavirus disease-19 (COVID-19) pandemic leaded to inevitable expeditious vaccine rollout without sufficient safety profile. Especially, severe acute respiratory syndrome coronavirus 2 infection has known to induce overreacted immune responses such as releasing of proteinase-3 and myeloperoxidase (MPO) by neutrophil. This overreacted immune response leads to the concern of the development of autoimmune diseases after COVID-19 vaccination. We report the case of de novo MPO-associated systemic vasculitis involving central nervous system following heterogeneous mRNA1273 COVID-19 booster vaccination.
