PURPOSE: To evaluate MR characteristics of acute disseminated encephalomyelitis (ADEM) in children, which was confirmed by clinical findings. MATERIALS AND METHODS: The subjects were six patients, who were diagnosed by clinical findings. One subject had recurrence one year after clinical improvement leading to one additional care with the total of seven. The modes of viral infections were as follows;four cases of non-specific upper respiratory tract infection, one of E-B virus, one of Japanese-B-encephalitis vaccination, and one of upper respiratory infection in Bruton's disease. The Gd-DTPA enhanced scan was performed in all cases. MR findings were evaluated in anatomic location of the lesions, presence or absence of contrast enhancement, and the temporal changes were also evaluated on follow-up MRI. RESULT: There were multifocal high signal intensity lesions on T2WI in all cases. The location of lesions were basal ganglia in five, thalamus and brain stem in four, and cerebral gray and white matter and cerebellar white matter in three. Bilaterality was 77%. There were contrast enhancement in two of three cerebral cortical lesions and one of three white matter lesions. The size of lesions decreased on the first follow-up MRI which were done after 1 month in 4 cases, but new lesions were developed in two cases. On the second follow-up MRI which were done 2 months after, all lesions were decreased in size and there was no newly developed lesion. However, in one case who had recurrent similar symptom after 1 year, several new lesions developed on follow-up MRI, and it was comidened as a recurrence. CONCLUSION: The characteristic MR findings of ADEM were multifocal bilateral white and gray matter lesions which were high signal intensities on T2WI. The majority of lesions improved on follow-up MRI, but occasionally showed multiphasic pattern.

A series of 41 patients in a vegetative state after severe head injury in presented. The patients selected were those who were in comatose state at least 2 weeks and observed more than 6 months. The vegetative state was more common before the age of 40(75.6%). The most common types of lesion causing vegetative state were subdural hematoma and epidural hematoma(56.1%). Twentyeight patients(68.1%) had a Glasgow coma score of 3 to 5. The two most frequent complications were urinary tract infections(80.5%) and bed sores(65.9%), but the most common cause of death was respiratory complication(60.0%). CT scans taken in the vegetative state showed variable evidences of cerebral atrophy, which were considered to be the results of the injury and had little value in predicting the outcome. At 6 months, the outcome was as follows : good recovery 4(9.8%) ; moderate disability 7(17.1%) ; severe disability 12(29.3%) ; vegetative state 10(24.4%) ; and dead 8(19.5%). Twenty-three patients(56.1%) came out of the vegetative state during a 6 month follow-up period. Vegetative state is not always permanent. Therefore, it seems necessary to distinguish perisstent vegetative state from vegetative state. The term, "persistent", means that the patient, if ever, came out of the vegetative state and in the event he did he usually remained in severe disability. 15 out of the 23 improved within 2 months, 14 out of the 15 improved to at least moderate disability. 8 out of the 23 improved after 2 months but all remained in severe disability. From these results we propose that the term "persitent" be applied to patients who remain in a vegetative state for more than 2 months.

Background: The defense and veterans pain rating scale (DVPRS) is a pain assessment tool combining a numerical rating scale (NRS) with descriptive words, colors, and facial expressions. This study aimed to validate the Korean version of the DVPRS (K-DVPRS) for postoperative pain assessment. Methods: This study included patients who underwent elective laparoscopic or robotic abdominal surgery. The original DVPRS was translated into Korean using a forward-backward method. Pain intensities at rest and during coughing were assessed at 24 and 48 hours postoperatively using the NRS and K-DVPRS, respectively. The EuroQol 5-Dimension 5-Level (EQ-5D-5L) questionnaire was also used. The validity, reliability, and responsiveness of the K-DVPRS were evaluated. Results: Of the 174 patients screened, 150 were enrolled, and 148 completed the study. The K-DVPRS had strong convergent validity with the NRS at 24 and 48 hours postoperatively (ρ: 0.75 to 0.78, all P < 0.001). Construct validity was confirmed by significant differences in pain scores based on surgical extent and duration. The internal consistency was acceptable (Cronbach’s alpha: 0.77 and 0.85 at 24 and 48 hours, respectively), and test-retest reliability at 24 hours was excellent (intraclass correlation coefficient: 0.90 at rest and 0.95 during coughing).Responsiveness, measured by Cliff’s effect size, was high from preoperative to 24 hours postoperatively and moderate from 24 to 48 hours. At 48 hours, the K-DVPRS had stronger correlations with the EQ-5D-5L index and EQVAS than with the NRS. Conclusions The K-DVPRS is a valid, reliable, and responsive tool for assessing postoperative pain in Korean patients.

OBJECTIVE: This study was carried out to investigate the correlations of the sperm DNA fragmentation index (DFI) with semen parameters and apoptosis, and to investigate the effects of density-gradient centrifugation (DGC) and magnetic-activated cell sorting (MACS) on reducing the proportion of sperm with DNA fragmentation and protamine deficiency. METHODS: Semen analysis and a sperm DNA fragmentation assay were performed to assess the correlations between semen parameters and the DFI in 458 semen samples. Sperm with progressive motility or non-apoptosis were isolated by DGC or MACS, respectively, in 29 normozoospermic semen samples. The effects of DGC or MACS alone and of DGC and MACS combined on reducing the amount of sperm in the sample with DNA fragmentation and protamine deficiency were investigated. RESULTS: The sperm DFI showed a significant correlation (r=–0.347, p<0.001) with sperm motility and morphology (r=–0.114, p<0.05) but not with other semen parameters. The DFI (11.5%±2.0%) of semen samples was significantly reduced by DGC (8.1%±4.1%) or MACS alone (7.4%±3.9%) (p<0.05). The DFI was significantly further reduced by a combination of DGC and MACS (4.1%±1.3%, p<0.05). Moreover, the combination of DGC and MACS (1.6%±1.1%, p<0.05) significantly reduced the protamine deficiency rate of semen samples compared to DGC (4.4%±3.2%) or MACS alone (3.4%±2.2%). CONCLUSION: The combination of DGC and MACS may be an effective method to isolate high-quality sperm with progressive motility, non-apoptosis, high DNA integrity, and low protamine deficiency in clinical use.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly. The mortality rate among infants and children without operation has been eighty to ninety-five percents and few patients survive till teen-age or adulthood. This anomaly was detected during elective coronary angiogram in a 32 year-old female patient with atypical chest pain. Reversible ischemia was demonstrated on myocardial 201Tl-SPECT. Coronary angiogram revealed anomalous origin of left coronary artery from pulmonary artery.

OBJECTIVE: Pain is very common in the elderly, so there is a high prevalence of analgesic use among this population. The purpose of this study was to assess patterns of analgesic use and evaluate factors associated with analgesic use in elderly patients. METHOD: The subjects of this study were patients over 65 years old hospitalized in a teaching hospital located in Chuncheon-si, Korea between January 1, 2014 and March 31, 2014. Data collection regarding analgesic prescriptions and baseline characteristics was conducted using computerized hospital database by medical information team. Logistic regression analysis was used to identify factors related to analgesic use. RESULTS: A total of 2,394 patients were finally included. Among these patients, 700 (29.2%) took analgesics; 521 (74.4%) out of these 700 patients were received opioid analgesics and 179 (25.6%) were received only non-opioid analgesics. The most frequently prescribed opioid analgesic was pethidine (45.7%), and the most frequently prescribed non-opioid analgesic was acetaminophen (44.1%). Fracture was associated with increased odds of opioid analgesic prescriptions (OR = 2.766, 95% CI = 2.019-3.790, p < 0.001) and any analgesic prescriptions (OR = 2.394, 95% CI = 1.766-3.244, p < 0.001). Stroke or cerebral infarction was associated with decreased odds of opioid analgesic prescriptions (OR = 0.636, 95% CI = 0.471-0.858, p = 0.003). CONCLUSION: A significant proportion of hospitalized elderly patients use analgesics. Health care professionals should consider factors associated with analgesic use in this population to improve pain management.
