One hundred sixteen C57 BL mice were painted with either 8-MOP, 5-MOP or TMP solution in concentrations of 0.02%, 0.1%, and 0.5% each and UVA irradiated. Skin biopsies were performed at 1, 3, 5 and 7 weeks after LJVA irradiation. The results measuring the number, area, and perimeter of the melanocytes after topical PLJVA were higher in the TMP-painted group than in the 8-MOP or 5-MOP painted groups. In all groups, the weekly changes showed an increasing value through five weeks. In comparing the drug concentrations used, 0.1% of chemicals produced the same or higher values than 0.5%. There have been few studies on the effects of 5-MOP in photochemotherapy. In tho study 5-MOP produced a pigment-producing effect similar to 8-MOP. Therefore, if topical PIJVA with 5-MOP is used in clinical practice, we could expect a significant therapeutic effect in vitiligo.

A clinical study was done on 16 cases of cerebellar hemorrhage and 3 cases of cerebellar infarction which were diagnosed with brain CT scan at Keimyung university Dongsan hospital from July 1981 to June 1985 and conclusions obtained are as follows. 1. The incidence of cerebellar hemorrhage and infarction was 3.5% and 0.6% of all spontaneous intracranial parenchymal hemorrhage and infarction, respectively. 2. The most prevalent age group was 7th decade and sex ratio was higher in male in cerebellar stroke. 3. Major single percipitating factor of cerebellar stroke was hypertension. 4. Most of cerebellar stroke showed catastrophic or sudden onset type. 5. The most common initial symptoms of cerebellar stroke were nausea and vomiting, followed by headache and dizziness or vertigo, in order of frequency. 6. The most common neurologic signs on admission were impaired consciousness, constricted pupil with preserved light reflex and cerebellar signs. 7. The common site of cerebellar hemorrhage was right hemisphere, followed by vermis and left hemisphere, in order of frequency, and that of cerebellar infarction was right posterior hemisphere. 8. The better the consciousness on admission, the better the outcome of cerebellar stroke. 9. The following parameters indicated good prognosis with medical therapy, so called benign cerebellar hemorrhage: clear consciousness on admission, gradual onset type, less than 20cc of hematoma, no or mild hydrocephalus, no ventricular hematoma, no vermis involvement on CT scan.

Journal of Korean Medical Science 2014;29(6):771-775
The Korean translated Appraisal of Guidelines for Research and Evaluation II (Korean AGREE II) instrument was distributed into Korean medical societies in 2011. However, inter-rater disagreement issues still exist. The Korean AGREE II scoring guide was therefore developed to reduce inter-rater differences. This study examines the effects of the Korean AGREE II scoring guide to reduce inter-rater differences. Appraisers were randomly assigned to two groups (Scoring Guide group and Non-Scoring Guide group). The Korean AGREE II instrument was provided to both groups. However, the scoring guide was offered to Scoring Guide group only. Total 14 appraisers were participated and each guideline was assessed by 8 appraisers. To evaluate the reliability of the Korean AGREE II scoring guide, correlation of scores among appraisers and domain-specific intra-class correlation (ICC) were compared. Most scores of two groups were comparable. Scoring Guide group showed higher reliability at all guidelines. They showed higher correlation among appraisers and higher ICC values at almost all domains. The scoring guide reduces the inter-rater disagreement and improves the overall reliability of the Korean-AGREE II instrument.

Journal of the Korean Neurological Association 1985;3(2):164-174
Clincal studies were made on 166 cases of spontaneous subarachnoid hemorrhage (SAH), were admitted to the keimyung university Dongsan hospital from January 1981 to March 1984. The age and sex distribution, causes of SAH, clinical symptoms and signs, computed tomographic (CT) findings, aneurysmal site, number and size, comparison between the highest density on CT findings and site of aneurysm confirmed by angiography,relationship between CT class and clinical grade, complication, and relationship between hospital course and clinical grade on admission were analysed. The results summarized as follow. 1. The most prevalent age group was between 41-60 years of age, and above 61 years, 31-40 years and below 30 years of age in the order of frequency. Male to female ratio was 43.4 : 56.6. 2. The most common causes of 100 cases of SAH confirmed by cerebral angiography was cerebral aneurysm (75 cases), and the other causes were unknown cause (16 cases), arteriovenous malformation (6 cases), moyamoya disease (3 cases) in the order of frequency. 3. The clinical symptoms on admission in the order of frequency were headache, nausea and vomiting, brief loss of consciousness, dizziness, seizure, and urinary incontinence. The neurological findings showed stiffneck, hemiparesis, cranial nerve palsies, papilledema and/or hemorrhage on the fundus, and Babinski sign in that order. 4. CT findings (158 cases) revealed typical high densities consistent with SAH in 125 cases (79.1%), associated with the low density (13 cases), and visible cerebral aneurysm (5 cases), while negative findings were 33 cases (20.9%). 5. The most common site of aneurysm among the 75 cases of SAH confirmed by the cerebral angiography was the region of the anterior communicating artery (AcomeA) which accounted for 30 cases (35.3%), and posterior communicating artery (PcomeA) and middle cerebral artery (MCA) 23 cases (27%), respectively, the internal carotid artery 5 cases (5.9%), the anterior ecrebral artery (ACA) 2 cases (2.4%), the posterior inferior cerebellar artery and basilar artery 1 cases (1.2%), respectively in the order of frequency. Among the 75 cases of cerebral aneurysms, single aneurysms were 67 cases (89.3%) and multiple aneurysms were 8 cases (10.7%). The most common size of the aneurysms was 6-10 mm (47 cases), and below 5 mm (30 cases), and above 10 mm (8 cases) in the order of frequency. 6. Sixteen out of 27 cases of AcomA aneurysms present the highest density on CT scan in the anterior hemispheric fissure, 9 out of 22 cases of PcomA aneurysms in syulvian fissure and 6 cases in suprasellar cistern, and all cases of MCA aneurysm (21 cases) in the ipsilateral aneurysmal site. 7. Comparison between CT grade by Davis (1980) and clinical grade by Hunt-Hesse (1968) revealed that the 93 of 94 patients (pts) with CT class 1 or 2 belong to under clinical grade 3, the 17 of 64 pts with CT class 3 or 4 belong to clinical grade IV or V, and the 17 of 18 pts with clinical grade IV or V belong to CT class 3 or 4. 8. The most common complication was the hydrocephalus (30.1%), and cerebral arterial spasm (24.1%), SIADH (8.4%), and rebleeding confirmed by lumbar puncture and/or CT (4.2%), in the order of frequency. 9. One hundred and four pts (62.7%) out of total 166 patient with SAH were improved, whereas 39 pts (23.5%) were not improved or signed out without clinical improvement, and 23 pts (13.8%) were died. The 81 (77.9%) of 104 pts who were improved belong to clinical grade I or II on admission, the 18 (78.3%) of 23 pts who were expired belong to clinical grade III or IV, and the 19 (48.7%) of 39 pts who were signed out without improvement belong to clinical grade III to V.

Korean Journal of Legal Medicine 2008;32(2):129-132
Paradoxical undressing is a well-known but uncommon phenomenon in hypothermic deaths. If an individual is found unusually undressed in cold weather and its autopsy finding is not related to any homicidal circumstance, the undressing is considered the victim s perimortem act accompanied in the hypothermic death. But unexperienced police staffs and scene investigators who are unaware of this perimortem phenomenon could take especially female death cases with paradoxical undressing for rape related homicides. The presenting case was initially considered a rape homicide but ruled a hypothermic death with the manner an accident through complete postmortem examinations including meticulous autopsy. We think this case is a good example for understanding the hypothermic death with pardoxical undressing and how to come to rule out homicide from it.

Lipoma is a common neoplasm in soft tissues. However, an intrapulmonary lipoma is a rare benign tumor. Patients with a bronchial lipoma might have a malignant potential related to their smoking history due to the case reports of lung cancer accompanied with lipoma. Endobronchial lipoma can cause irreversible parenchymal lung damage if not diagnosed and treated early. Therefore, it should initially be treated by fiberoptic bronchoscopy or surgery depending on the status of distal parenchymal lung damage. Bronchiolitis obliterans with organizing pneumonia (BOOP) is a pathological syndrome that is defined by the presence of buds of granulation tissue consisting of fibroblasts and collagen within the lumen of the distal air spaces. BOOP is caused by drug intoxication, connective tissue disease, infection, obstructive pneumonia, tumors, or an unknown etiology. We encountered a 58 year-old male patient with endobronchial lipoma, causing the collapse of the right middle and lower lobes, and BOOP due to obstructive pneumonia.

BACKGROUND/AIMS: The dose of mycophenolate mofetil (MMF) has been reduced in Asia due to side effects associated with the conventional fixed dose of 2-3 g/day. We aimed to determine the pharmacokinetics of a reduced dose of MMF and to validate its feasibility in combination with tacrolimus in living-donor liver transplantation (LDLT). METHODS: Two sequential studies were performed in adult LDLT between October 2009 and 2011. First, we performed a prospective pharmacokinetic study in 15 recipients. We measured the area under the curve from 0 to 12 hours (AUC0-12) for mycophenolic acid at postoperative days 7 and 14, and we performed a protocol biopsy before discharge. Second, among 215 recipients, we reviewed 74 patients who were initially administered a reduced dose of MMF (1.0 g/day) with tacrolimus (trough, 8-12 ng/mL during the first month, and 5-8 ng/mL thereafter), with a 1-year follow-up. We performed protocol biopsies at 2 weeks and 1 year post-LDLT. RESULTS: In the first part of study, AUC0-12 was less than 30 mgh/L in 93.3% of cases. In the second, validating study, 41.9% of the recipients needed dose reduction or cessation due to side effects within the first year after LDLT. At 12 months post-LDLT, 17.6% of the recipients were administered a lower dose of MMF (0.5 g/day), and 16.2% needed permanent cessation due to side effects. The 1- and 12-month rejection-free survival rates were 98.6% and 97.3%, respectively. CONCLUSIONS: A reduced dose of MMF was associated with low blood levels compared to the existing recommended therapeutic range. However, reducing the dose of MMF combined with a low level of tacrolimus was feasible clinically, with an excellent short-term outcome in LDLT.

This study provides a statistical analysis of 1,226 cases of death occurring in Area 8, Seoul Metropolitan Police Agency (Gangseo, Yangcheon, and Guro Police Stations) from January 1 to December 31, 2017. There were 427 postmortem inspection cases in Gangseo, 393 in Yangcheon, 377 in Guro, and 29 in other areas. The number of autopsy cases was 69 in Gangseo, 70 in Yangcheon, 86 in Guro, and seven in other areas. According to the postmortem inspection reports, there were 593 cases of natural death and 336 cases of unnatural death, while in 297 cases the cause of death was unknown. Of the 297 unknown cases, autopsy rates from each police station were as follows: 54 of 99 cases (54.5%) in Gangseo, 60 of 101 cases (59.4%) in Yangcheon, 67 of 93 cases (72.0%) in Guro, and in all four cases (100%) from other areas. Unnatural deaths included 215 cases of suicide, nine cases of homicide, and 64 accidental death, while 48 cases were undetermined. Among the unnatural deaths, the cause of death included 138 cases of hanging, 72 cases of falls from a height, and 32 cases of poisoning. Since this statistical study is based on actual postmortem inspection data for 1,226 cases of death in the eight areas of Seoul (excluding deaths from traffic accidents), it raises issues relating to the current postmortem inspection system, and can be used as reference material for a comprehensive overview of causes of death.

Nocardia farcinia, an aerobic, gram-positive bacilli actinomycetes of the genus Nocardia, is an uncommon pathogen found in humans. The most common Nocardia infection sites are the lung, central nervous system, and skin. Even though hematogenous dissemination can occur, isolation of the organism from blood cultures is very rare. We report a case of Nocardia infection that was isolated on blood cultures. A 59-year-old male with a medical history that includes a liver transplantation 6-years prior due to hepatocellular carcinoma secondary to chronic hepatitis B, developed pneumonia and was transferred to Severance Hospital. At the time of admission, the patient's initial exam showed hypothermia, tachypnea, and hypotension. His chest radiograph showed severe pneumonia and a large abscess on left upper lobe. Under the presumptive diagnosis of bacterial pneumonia or other opportunistic infection, we started broad spectrum antibiotics. However, he developed Nocardia sepsis, rapidly deteriorated, and subsequently died.
