In our clinic, 60 cases of spinal cord injury were collected for 4 years until the end of August 1972. 44 Patients were decompressive laminectomy performed as soon as possible when there patients arrived to our hospital, only 10 cases were almost completely recovered of function, will the prognosis of spinal cord injury is very serious. The preservation of pain sensation in patients with motor paralysis and positive Queckenstedt's test following acute cord compression is a favorable prognostic sign.

Eight patients, with brain abscess or localized cerebritis proved histologically, were seen at The National Medical Center from 1971 to 1972, and 3 died, which is 37.5% mortality. Evidence of infection was often minimal in patients with brain abscess. The presence of increased erythrocyte sedimentation rate, highly suggestive of a cerebral abscess when an intracranial space-occupying lesion is suspected. The cerebral angiography and EEG were the best diagnostic tests. Early accurate diagnosis and early intracranial relieving with surgical procedure were most important factor in management of brain abscess. Primary excision of the abscess was considered to be the most satisfactory therapy.

To investigate the morphological changes in skeletal muscle produced by colchicines toxicity, 42/rats were given a single intraperitoneal dose(0.4mg/Kg) of colchicines, and the animals were killed at daily intervals up to 7 days. The results of light microscopic and electron microscopic observations are summarized as follows; 1) At the light microscopic level, colchicines treated arts show non-inflammatory, nonspecific scattered degeneration or necrosis of myofibers irrespective of location of the skeletal muscle. No significant pathologic changes in peripheral nerve fibers distributed in affected muscles are seen. 2) The general ultrastructural changes are dilation of sarcoplasmic reticulum, swelling and pleomorphism of mitochondria, and appearance of membraneous bodies characterized by a single or multiple concentric layers of membranes in subsarcolemmal zones and intermyofibrillar zones, and focal necrosis or loss of myofibrils. The incidence and severity of these changes show gradual increase and reach maximal peak 3 days after colchicines administration, and then they show gradual decrease. Nerve fibers and motor-end plates show no difference compared with the control. 3) The observations are consistent with the opinion that the muscle weakness or paresis produced by toxic dose of colchicines is not of neuropathic, but of myopathic alterations. 4) The membraneous bodies are classified into the following 3 types;Type I is those bodies outlined by a few concentric membranes with osmiophilic granules, small vesicles, free ribosomes, and mitochondria in central zone. Type II is those outlined by several concentric layers of membranes with osmiophilic granules, small vesicles, free ribosomes, and mitochondria in center. Type III is those outlined by multilayered or thick concentric membranes with osmiophilic granules, small vesicles, free ribosomes, and mitochondria in central zone, frequently with complicated lamellar structures. 5) The skeletal muscle lesions produced by colchicines toxicity may be categorized into those degenerative changes characterized by the appearance of membraneous bodies. And, morphologically, it is presumed that the membraneous bodies are heterogenous in origin, alterations of subcellular structures such as sarcoplasmic reticulum, mitochondria, and lysosome.

Yakovlev demonstrated that the Schizencephalies appear to result from injury to developing cerebral vesicles in the second month of intrauterine life. There is a total loss of neurons in restricted symmetrical zones of each developing hemisphere and on either side of the resulting cleft-shaped defects are evidences of subtotal injury to developing neuroblasts. A case of a 4 years old male with Schizencephaly is reported.

Human is infected by third stage filariform larvae of Strongyloides stercoralis which is a soil-transmitted nematode. Rhabditiform larvae passed in feces can transform into infectious filariform larvae either directly or after a free living phase of development. Most infected patients may be asymptomatic or have mild cutaneous symptoms or induces non-specific complaints such as moderate abdominal pain, nausea and diarrhea. However, in immunocompromised hosts, the parasite is augmented by autoinfection, resulting in hyperinfection and can disseminate widely and can be fatal. We report a case of strongyloidiasis associated with intestinal obstruction in a patient with alcoholic liver disease.

Recent studies indicate that patients with chronic graft-versus-host disease (GVHD) are not expected to show positivity for anti-mitochondrial antibody (AMA), which is a specific disease marker for primary biliary cirrhosis (PBC). A differential diagnosis between PBC and hepatic involvement of GVHD based on clinical manifestations and pathologic study is difficult because both diseases show similar results. Therefore, the presence of AMA may be important for distinguishing each disease. Here, we report a case of hepatic involvement of chronic GVHD with positive AMA, in which the pathologic findings and initial presentation of clinical findings were compatible with both PBC and chronic GVHD.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread globally, leading to the coronavirus disease 2019 (COVID-19) pandemic. Because a significant proportion of the COVID-19 confirmed cases were concentrated in the capital metropolitan area of South Korea, and a large proportion of the population in the area had been adequately vaccinated against COVID-19, we conducted a seroprevalence surveillance study focusing on the residents of the capital metropolitan area in South Korea. Methods: We used a quota-sampling method to obtain blood samples from 1,000 individuals per round, equally stratified across seven age categories and sexes and regions, from five medical institutions located within the capital metropolitan area of South Korea. During five consecutive months (rounds) between January 2022 and May 2022, a total of 5,000 samples were analyzed for anti-spike (S) and anti-nucleocapsid (N) antibodies. Results: High anti-S seropositivity was observed in all age groups, which corresponded to the vaccine coverage during the study period. Both the cumulative incidence based on polymerase chain reaction (PCR) and the estimated seroprevalence based on anti-N seropositivity increased in the fourth and fifth rounds, which corresponded to April 2022 and May 2022. Seroprevalence coincided with the cumulative incidence during the first three rounds, but exceeded from the fourth survey onwards when infection with omicron variants was increased rapidly in Korea. Conclusion Seroprevalence confirmed the number of infection cases outside of PCR testing-based surveillance. Seroepidemiological surveillance can help us understand vaccine responses and detect hidden infections, thereby providing appropriate public health guidance for achieving population-level immunity.

PURPOSE: We propose an equation that predicts graft function after kidney transplantation by using donated kidney volume and recipient body surface area (BSA). MATERIALS AND METHODS: Included were 261 cases of living kidney transplantation between 2007 and 2009. Preoperative computed tomography scans were performed and the donated kidney volume was measured by use of a three-dimensional reconstruction program (Ripidia). The estimated glomerular filtration rate (eGFR) was calculated by using the modification of diet in renal disease formula. Donated kidney volume, preoperative renal function, and demographic factors of both donors and recipients were evaluated as predictors. RESULTS: The mean ages of the donors and recipients were 40.8 and 41.6 years, respectively. The mean donated kidney volume and donated kidney volume/recipient BSA ratio were 153.4 mL and 96.9 mL/m2, respectively. Mean preoperative and postoperative 12-month eGFR of recipients were 7.1 and 59.7 mL/min, respectively, and the mean preoperative eGFR of donors was 92.2 mL/min. Donated kidney volume/recipient BSA ratio, donor age, and recipient gender were the significant predictors of eGFR level (p<0.001) and eGFR<45 mL/min at postoperative 12 months (p=0.005, p<0.001, and p=0.006). From the multiple linear regression equation and predicted probability from logistic regression, we could calculate the equation for the ratio of living donor kidney volume to recipient BSA on graft function. CONCLUSIONS: Graft kidney volume/recipient BSA ratio, donor age, and recipient gender were predictors of graft function 12 months after kidney transplantation. Although we are concerned only with the preoperative, this equation model could help physicians to counsel patients concerning their postoperative prognosis and to avoid insufficient volume donations.

Purpose: The purpose of this study is to determine the risk adjusted nosocomial infection (NI) rate and distribution of Nls and their causative pathogens in adult lCU. Methods: Prospective surveillance was performed at 12 lCU's of 5 acute care hospitals in Seoul and Kyonggi Do during a 3-months period from May to July 2002. The case finding was done by direct reviews of medical charts regularly for all patients by ICPs using CDC definitions. Results: Total NI rate was 10.18/1,000 patient-days in Medical-surgical ICU (MSICU) and 12.35/1,000 patient-days in Neurosurgucal ICU(NCI). Risk adjusted infection rate was 3.44 in indwelling catheter associated UTI 2.12 in central line associated BSI. 3.51/1,000 device-days in ventilator associated pneumonia in MSICU. There were 3.72, 2.26, 6.06/1,000 device-days in NCU. The infection rate by leu type showed no significant difference. The distribution of Nls were PNEU (28.99%). UTI (28.99%), BSI (18,84%), SSI(4.35%) in MSICU, and UTI(48.0%), PNEU(24.0%), BSI (14.0%), SSI(6.I) in NCU. The most commonly isolated organisms were Candida spp (38.6%), Enterococcus spp. (13.4%) in UTI, Staphylococcus aureus(36.2%), p. aeruginosa(18.8%) in PNEU and Coagulase negative staphylococcus(44.1%). S. aureus (14.7%) in BSL, S. aureus (19.8%) was the most common organism from overall nosocomial infections in the ICU, and 96.3% of S. aureus were MRSA. Conclusion: Distribution of site-specific nosocomial infection and isolated organisms were similar to the results of KOSNIC (Korea society for nosocomial infection control) surveillance in 1996. However, the total infection rate and a risk adjusted infection rate at MSJCU is lower than 1996's. This decrease is considered to be a result of efforts to prevention and control nosocomial infections.
