Among the fifty-three clinical isolates of Haemophilus influenzae, nineteen isolates including eight isolates of each biotype I-VIII, six of serotype b (Hib) strains and five of nontypeable strains were characterized by SDS-PAGE about outer membrane protein (OMP), restriction enzyme analysis (REA) and rRNA gene restriction pattems. OMP patterns showed to common band patterns in each H. influenzae isolate. Based on the two major proteins, 31KDa-38KDa, isolated strains were classified into 7 subtypes. In the OMP patterns about biotype and serotype, the specific pattern of each biotype was not distinguishable, but all of the serotype b strains were shown identical unique pattern, therefore it made distinctive difference with nontypeable strains. The digested genomic DNAs with EcoRI were identical result with rRNA gene restriction. It was more subdivided into 10 ribotypes. The most common ribotype I and serotype 1 accounted for 6 strains (31.6%) and 7 strains (36.8%) of the 19 clinical isolates, respectively. Hib isolates that were both OMP subtype 1 and ribotype I accounted for 2 strains (10.5%). In the epidemiologically unrelated strains, the putative association between the subtypes could not be confirmed. According to these results, the three methods were discriminatory and appropriate techniques for epidemiological studies of H. influenzae.

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

In a patient receiving 5-fluorouracil and levamisole, neurologic deficits suggest the cerebral demyelinating syndrome as a differential diagnosis. The authors report a patient diagnosed as multifocal inflammatory leukoencephalopathy for which thallium-201 ((201)Tl) single photon emission computed tomography (SPECT) and proton magnetic resonance spectroscopy (MRS) were employed as noninvasive diagnostic tools. (201)Tl SPECT study was negative and proton MRS showed an increase of choline and lactate and well preserved N-acetylaspartate. These findings support histopathologic findings of multifocal inflammatory leukoencephalopathy revealing demyelination with relative axonal sparing in the patient.

BACKGROUND: Although there have been many studies about onychomycosis due to nondermatophytic molds (NDM), few studies about etiologic agents including NDM in onychomycosis have been reported in Korea. Objective: This study investigated onychomycosis due to NDM in the Gyeongju area of Korea. OBJECTIVE: This study investigated onychomycosis due to NDM in the Gyeongju area of Korea. METHODS: In the 10-year period from 1999~2009, we reviewed 59 patients with onychomycosis due to NDM. The etiologic agents were identified by cultures on Sabouraud's Dextrose agar with and without cycloheximide. In some cases, internal transcribed spacer sequence analysis was done. NDM isolated considered pathogens when the presence of fungal elements was identified by direct microscopy observation and in follow-up cultures yielding the same fungi. RESULTS: Onychomycosis due to NDM comprised 2.3% of all onychomycosis. Of the 59 patients with onychomycosis due to NDM, 84.7% were toenail onychomycosis and 15.3% were fingernail onychomycosis. The incidence rate was highest in the fifth decade (27.1%). The ratio of male to female patients was 1:1.6. The frequency of associated diseases, in descending order, was hypertension, diabetes mellitus, and cerebral hematoma. Distal and lateral subungual onychomycosis (86.4%) was the most common clinical type of onychomycosis. Aspergillus spp. was the most frequently isolated etiologic agent of onychomycosis due to NDM (83.0%). Other causative agents were Scopulariopsis brevicaulis (10.2%), Acremonium spp. (3.4%), Fusarium solani (1.7%), and Chaetomium globosum (1.7%). CONCLUSION: Because of the increase in onychomycosis due to NDM, we suggest the need of a careful mycological examination in patients with onychomycosis.

Various sequences have been developed for MRI to aid in the radiologic diagnosis. Among the various MR sequences, susceptibility-weighted imaging (SWI) is a high-spatial-resolution, threedimensional gradient-echo MR sequence, which is very sensitive in detecting deoxyhemoglobin, ferritin, hemosiderin, and bone minerals through local magnetic field distortion. In this regard, SWI has been used for the diagnosis and treatment of various neurologic disorders, and the improved image quality has enabled to acquire more useful information for radiologists.Here, we explain the principle of various signals on SWI arising in neurological disorders and provide a retrospective review of many cases of clinically or pathologically proven disease or components with distinctive imaging features of various neurological diseases. Additionally, we outline a short and condensed overview of principles of SWI in relation to neurological disorders and describe various cases with characteristic imaging features on SWI. There are many different types diseases involving the brain parenchyma, and they have distinct SWI features.SWI is an effective imaging tool that provides complementary information for the diagnosis of various diseases.

BACKGROUND: Fulminant hepatic failure is characterized by rapid progressive liver failure with the onset of encephalopathy within a few weeks of the appearance of jaundice. This illness is frequently complicated by hemodynamic instability, multiple organ dysfunction and intracranial hypertension associated with cerebral edema, which is the most common cause of death in this condition. We reviewed 8 cases of liver transplantation with fulminant hepatic failure with respect to anesthetic management and neurologic monitoring. METHODS: We analyzed anesthetic management, intracranial pressure (ICP), cerebral perfusion pressure (CPP), jugular venous oxygen saturation (SjvO2) and hemodynamics retrospectively during liver transplantation in 8 patients with fulminant hepatic failure. Intracranial hypertension was defined as an ICP >or= 20 mmHg for at least 5 minutes. The goal of management is to keep the CPP above 40 - 50 mmHg and ICP below 30 - 40 mmHg. There were 3 cases of hepatorenal syndrome and continous veno-venous hemodiafiltration (CVVHD) was used in 2 cases. RESULTS: All patients showed characteristic hyperdynamic circulation with severe vasodilation and vasopressive drugs were needed to maintain CPP. The episodes of intracranial hypertension occurred in all patients during transplantation. To decrease ICP, medical therapy with mannitol, furosemide and thiopental infusion were required. Intracranial hemorrhagic complications occurred in 3 cases. SjvO2 decreased transiently below 60% in 3 cases. However, it was improved with an increase of PaCO2 by hypoventilation and maintained above 60 - 80% in all cases. CONCLUSIONS: This data suggests that there is a risk of brain injury secondary to elevated ICP and low CPP during liver transplantation. ICP, CPP and SjvO2 monitoring in patients with fulminant hepatic failure can be useful for the prompt recognition of intracranial hypertension and for guiding therapy. However, correction of the coagulopathy before placement of the ICP tranducer must be performed to prevent hemorragic complications.
