Therapeutic plasma exchange is used in almost every condition in which there is a plasma factor thought possibly to the etiology or pathogenesis of a disease or one of its manifestations. In order to evaluate plasma exchange using fresh frozen plasma as replacement solution, eighty four therapeutic plasma exchanges were carried out in eighteen patients. In standardized procedures, 1.5 times the calculated plasma volume was replaced with a Hartman's solution and fresh frozen plasma. Anticoagulation was achieved using a whole venous blood to 2.5% trisodium citrate in the ratio of 10 to 1. Total calcium, phosphorus, glucose, urea nitrogen, creatinine, bilirubin, alkaline phosphatase, amylase, creatine kinase, IgG, C3, total white and red blood cell count, hemoglobin, and differential count were not significantly affected by the procedure. In contrast, serum cholesterol, total protein, albumin, aspartate aminotransferase, alanine aminotransferase, ionized calcium, IgM, C4 and platelet were significantly decreased by the plasma exchange. All these measurements had returned to the first pre-exchange level within 24 hours, while the C4 and platelet count took between 24 and 72 hours, and the IgM level, between 72 hours and 1 week. These data indicated that in an isovolemic plasma exchange there was a transient but rapidly reversible effect on all the components studied, with C4 and platelet count, returning more slowly to pre-exchange level than the others, and IgM levels responding the slowest. In summary, plasma exchanges using fresh frozen plasma as replacement solution were assumed to be not significantly affected the function of various organs.

Kerion celsi is a severe inflammatory type of tinea capitis that presents as an inflammatory, boggy mass with broken hairs and hair loss. It is usually occurred in children between the age of 4 and 14 years that caused by zoophilic or geophilic pathogens such as Microsporum(M.) canis, Trichophyton(T.) mentagrophytes, T. verrucosum, M. gypseum, T. verrucosum was chiefly found from cattle which infect the human through direct contact. We report a case of kerion celsi caused by T. verrucosum probably transmitted from cattle in a 3-year-old boy. The patient had a solitary, tender, 6.0 x 5.5 cm sized, erythematous boggy plaque and pustules with hair loss on the right side of occipital scalp for 2 weeks. Chains of chlamydoconidia were observed in KOH mount and slide culture by light microscopy. The nucleotide sequence of internal transcribed spacer (ITS) region for clinical isolate was identical to that of T. verrucosum strain IFM 57570. He was treated with 125 mg of terbinafine daily for 12 weeks and short term therapy of low dose of prednisolone. Skin lesion was cured without recurrence.

Severe head injury results in the suppression of cellular immunity associated with dysfunctioning of effector lymphocytes, such as helper T cells(CD4) (and cytotoxic T cells(CD8). Despite progress in the management of increased intracranial pressure following head injury, infection remains the most common complication and the primary cause of prolonged hospitalization and death. This study attempts to assess the cellular immune function following head injury according to the degree of severity, and to establish the clinically available parameters of cell mediated immune(CMI) function, which can then be used for coherent prediction of infection risk. Eighteem head injury patients without severe systemic injury, who divided into three subgroups depending on the severity of head injury, were estimated with the use of CMI multitest kit(Merieux Institute, France) to test delayed-type hypersensitivity(DTH) and enumerated the circulating lymphocyte subpopulation(pan T-cell marker CD3, helper T cell marker CD4, cytotoxic T cell marker CD8 and B-cell marker CD19) on the 1st, 7th, and 21th day of injury. Patients were monitored for evidence of infection for this period. Fourteen patients had no reaction to any antigens of the DTH skin test(anergy) and the remaining four patients had also some degree of anergy. Seven patients became infected and all of them were anergic. There were significant decrease of circulating effector T lymphocytes, both CD4-positive and CD8-positive cells, within 24 hours of injury in the mild as well as the moderate and severe head injury group. CD4-positive cells were nearly completely recovered by the 7th day of injury. CD8-positive cells had sustained significant decrease even after 3 weeks of injury. There was no significant change in pan T-cells(CD3-positive cells) and B-cells(CD19-positive cells). The results suggest that DTH skin test and effector T cell enumeration are both relatively simple and highly sensitive parameters for monitoring CMI function. Especially, anergy of DTH skin test can be used for indicator to predict risk of infection. Mild as well as moderate and severe head injuries may result in the suppression of cellular immunity associated with the dysfunctioning of effector T cell.

PURPOSE: We attempted to evaluate the diagnostic usefulness of the degree of perilesional edema around intracerebral hematoma in predicting the underlying cause. MATERIALS AND METHODS: This study included 54 patients with intracerebral hematoma for whom the underlying cause was confirmed by biopsy, radiological or clinical methods. Cases of subarachnoid hemorrhage, hemorrhagic transformation of cerebral infarction and intraventricular hemorrhage were excluded. The lesion size was defined as the average value of the longest axis and the axis perpendicular to this. The size of the perilesional edema was defined as the longest width of the edema. In all cases, the sizes of the lesion and edema were measured on the T2 weighted image. We defined the edema ratio as the edema size divided by the lesion size. RESULTS:23 cases were diagnosed as intracerebral hemorrhage due to neoplastic conditions, such as metastasis (n=17), glioblastoma (n=5), hemangioblastoma(n=1). 31 cases were caused by non-neoplastic conditions, such as spontaneous hypertensive hemorrhage (n=23), arteriovenous malformation (n=4), cavernous angioma (n=3), and moya-moya disease (n=1). In fourteen cases, which were confirmed as malignant intracerebral hemorrhage, the edema ratio was more than 100%. Of the other cases, only 8 were confirmed as malignant intracerebral hemorrhage. It was found that the larger the edema ratio, the more malignant the intracerebral hemorrhage, and this result was statistically significant (p<0.001). CONCLUSION: Measurement of perilesional edema and the intracerebral hematoma ratio may be useful in predicting the underlying causes.

Duodenal diverticula are detected in up to 27% of patients undergoing upper gastrointestinal tract evaluation with periampullary diverticula (PAD) being the most common type. Although PAD usually do not cause symptoms, it can serve as a source of obstructive jaundice even when choledocholithiasis or tumor is not present. This duodenal diverticulum obstructive jaundice syndrome is called Lemmel's syndrome. An 81-yr-old woman came to the emergency room with obstructive jaundice and cholangitis. Abdominal CT scan revealed stony opacity on distal CBD with CBD dilatation. ERCP was performed to remove the stone. However, the stone was not located in the CBD but rather inside the PAD. After removal of the enterolith within the PAD, all her symptoms resolved. Recognition of this condition is important since misdiagnosis could lead to mismanagement and therapeutic delay. Lemmel's syndrome should always be included as one of the differential diagnosis of obstructive jaundice when PAD are present.

Fusarium(F.) species are hyalohyphomycetes isolated from plants, soil and air. Fusarium species can cause disseminated infections with involvement of multiple organs and numerous skin lesions in immunocompromised patients. And they can also cause local skin infections of trauma site. We report a case of localized skin infection by F. oxysporum in a 63-year-old immunocompetent woman. She presented with multiple, mild pruritic, 1.5 x 1.5 cm-sized, erythematous maculopapules on the left cheek after cosmetic procedure 4 months ago. Histopathologically, suppurative granulomatous inflammation, fungal elements were observed in dermis. Fungal culture on Sabouraud's dextrose agar showed rapid growing, whitish, cottony colonies at 25degrees C for 1 week. Numerous fusoid macroconidia were observed in slide culture by light microscopy. The nucleotide sequences of the internal transcribed spacer (ITS) region of clinical sample identical to that of F. oxysporum CID 220 strain (GenBank accession number HQ829117.1). The patient had been treated with itraconazole for 6 months. The skin lesion was improved. There was no recurrence 6 months after treatment.

OBJECTIVE: This study aimed to compare the accuracy of subjective memory complaints, informant-reports for cognitive declines, and their combination for screening cognitive disorders in memory clinic setting. METHODS: One-hundred thirtytwo cognitively normal (CN), 136 mild cognitive impairment (MCI), and 546 dementia who visited the memory clinic in the Seoul National University Hospital underwent standardized clinical evaluation and comprehensive neuropsychological assessment. The Subjective Memory Complaints Questionnaire (SMCQ) and the Seoul Informant Report Questionnaire for Dementia (SIRQD) were used to assess subjective memory complaints and informant-reports for cognitive declines, respectively. RESULTS: Both SMCQ and SIRQD showed significant screening ability for MCI, dementia, and overall cognitive disorder (CDall: MCI plus dementia) (screening accuracy: 60.1–94.6%). The combination of SMCQ and SIRQD (SMCQ+SIRQD) was found to have significantly better screening accuracy compared to SMCQ alone for any cognitive disorders. SMCQ+SIRQD also significantly improved screening accuracy of SIRQD alone for MCI and CDall, but not for dementia. CONCLUSION: Our findings suggest that the combined information of both subjective memory complaints and informant-reports for cognitive declines can improve MCI screening by each individual information, while such combination appears not better than informant-reports in regard of dementia screening.

BACKGROUND: Both aspirin and simvastatin are prescribed as treatments or prevention of cardiovascular diseases. The aim of this study was to investigate the influence of simvastatin on pharmacokinetics and pharmacodynamics of aspirin after oral co-administration in healthy subjects. METHODS: Subjects were orally administered aspirin 100 mg for 7 days followed by co-administration of aspirin 100 mg and simvastatin 40 mg for 7 days once daily. A series of blood samples were collected before and till 24hours after drug administration on Day 1 (single-dose of aspirin), Day 7 (multiple-dose of aspirin) and Day 14 (multiple-dose of aspirin and simvastatin). The effects of simvastatin on pharmacokinetics of acetylsalicylic acid and salicylic acid were assessed with the 90 % confidence intervals (CIs) of thegeometric mean ratios (GMRs) of Day 14 over Day 7 for maximum plasma concentration (Cmax) and the area under the concentration-time curve (AUC0-24). Pharmacodynamics was assessed with maximal changes of platelet aggregation from baseline. RESULTS: Twenty-fourhealthy men aged 20 to 36 years were enrolled and 23 of them completed the study. GMRs (90 % CIs) of Cmax and AUC0-24 for acetylsalicylic acid were 1.21 (1.04 - 1.42) and 1.28 (1.19 - 1.38), respectively. For salicylic acid, GMRs of Cmax and AUC0-24 were 0.96 (0.91 - 1.00) and 1.00 (0.97 - 1.04), respectively. Maximal changes of platelet aggregation on Day 7 and Day 14 from baseline were not significantly different (p=0.41); 87.5 +/- 8.8 % and 87.3 +/- 9.2 %, respectively. CONCLUSION: Coadministration of simvastatin slightly increased the systemic exposure of acetylsalicylic acid with no changes of systemic exposure of salicylic acid or inhibition of platelet aggregation.
