PURPOSE: Peripheral T-cell lymphomas(PTCL) show diverse clinical and histological characteristics and should be understood as mixtures of heterogeneous entities. Although many clinical and biological parameters have been proposed for classifying PTCL into different prognostic groups, few parameters have turned out to be appropriate for classification. To investigate the clinical significance of FUO presentation in PTCL, comparisons of clinical parameters were performed using non-FUO presentation as a control. MATERIALS AND METHODS: 66 cases of Korean PTCL were divided into FUO group and non-FUO group according to the presentation and compared with each other. RESULTS: Among 66 patients of PTCL, 19 patients presented with FUO. Compared with non-FUO group, FUO group showed no significant age and sex ratio differences. FUO group showed more advanced stage, worse performance status than non-FUO group. Predominant sites of definite diagnosis were skin, gastrointestinal tract and liver in FUO group and nasal cavity and paranasal sinus in non-FUO group. There were no significant differences between histologic classifications of both groups. Survival analysis revealed significant differences between both groups. FUO group showed significantly shorter survival. Prognostic factor analysis(multivariate) was done with stage, LDH level, performance status, and FUO status. FUO status, stage and performance status were significant determinants of survival, but LDH level proved to have no prognostic implication. CONCLUSION: PTCL with FUO presentation showed such distinct characteristics that the authors propose fever of unknown origin(FUO) as a clinical parameter for classifying PTCL. Further studies are needed to identify biological parameters which characterize PTCL with FUO presentation.

Retroperitoneal cystic lymphangioma is a rare benign tumor which had previously been difficult to diagnose preoperatively by conventional radiographic technique(1). Recent reports describe the computed tomographic and ultrasonographic findings in cystic lymphangioma(1,2). We report a case of retroperitoneal cystic lymphangioma, accurately diagnosed by lymphography, with computed tomographic findings and percutaneous drainage findings. To the best of out knowledge, this is the most aged case of retroperitoneal cystic lymphangioma of preoperatively diagnosed.

OBJECTIVES: This study aimed to compare the diagnostic validities between the Korean version of Mini-Mental State Examination (MMSE-K) and the Korean MMSE (K-MMSE) for screening of dementia and to investigate the possible changes of optimal cutoff scores of each instrument according to age, gender, and educational level. METHODS: 746 community residents aged 65 or over in two areas of Kwangju, Republic of Korea were assessed with MMSE-K and K-MMSE and were also evaluated for the diagnoses of dementia (DSM-IV). RESULTS: The performances, measured by area under receiver operating characteristics curve, of MMSE-K and K-MMSE against DSM-IV dementia were 0.93 and 0.94 respectively. The optimal cutoff scores for screening of dementia were 21|22 in MMSE-K and 17|18 in K-MMSE. Changes of the optimal cutoff scores according to age, gender, and educational level of the sample were 0-2 in the MMSE-K and 2-5 in the K-MMSE. CONCLUSIONS: MMSE-K and K-MMSE could be used for screening of dementia with excellent validities. For primary health care staff, however, it was suggested that MMSE-K would be more feasible than K-MMSE because the former had less changes in the optimal cutoff scores and was easier to interpret its results than the latter.

OBJECTIVE: The purpose of this study was to evaluated the effects of alcohol on neurocognitive function, psychomotor performance and subjective response in healthy Korean adults with different ALDH2 genotypes. METHOD: A total of 24 males, half with active ALDH2*1/2*1 and the other with inactive ALDH2*1/2*1, was selected through genotyping using restriction fragment length polymorphism. In a double-blind, placebo-controlled cross-over design, each subject consumed 0.5g/kg dose of alcohol, given as a mixture of 40% vodka and orange juice, and placebo(orange juice) on two separate occasions on an average of weekly intervals. The blood alcohol concentrations(BACs) were measured using a breath analyzer at baseline and at 30, 60 minutes after drinking. P300s were measured at baseline and at 30 minutes after alcohol and placebo intake. Vital signs and psychomotor performance[Critical Flicker Fusion Threshold(CFFT), Choice Reaction Time(CRT), Digit Symbol Substitution(DSS)] were measured at baseline and at 60 minutes after alcohol and placebo intake. Subjective responses were measured at the end of the study. The statistical analysis focused on whether there were any differences between groups with different ALDH2 genotypes. RESULTS: The major results are as follows. 1) BACs in inactive group were overall equivalent to those in the active group. Only in terms of time, BACs were significantly higher overall at 30 minutes than at 60 minutes after alcohol intake. 2) Pulse rates were significantly increased after alcohol intake compared with placebo, and the increase was greater in the inactive than in the active group. 3) P300 latencies in leads Fz(frontal), Cz(cental) and Pz(parietal) were significantly increased after alcohol intake compared to placebo, and the increase was greater in the inactive than in the active group. P300 amplitudes in leads Cz and Pz were significantly decreased overall after alcohol intake compared to placebo. 4) Compared with placebo, alcohol produced significant effect on the psychomotor performance : impairment in the inactive group, improvement in the active group. 5) Compared with placebo, alcohol significantly induced a negative or an intense effect on the subjective responses in the inactive group, but little negative and even a somewhat positive effect in the active group. CONCLUSIONS: These results suggest that ALDH isozyme variance might be an important factor to determine the effects of acute dose of alcohol on the various psychobehavioural functions and also to determine the alcohol use pattern and to predict the future development of alcohol overuse and/or abuse.

Bleeding and thrombocytopenia are important adverse effects of abciximab. The incidence of abciximab-induced acute profound thrombocytopenia (APT) is low. APT is defined as an abrupt drop in platelet count to <20,000/microL that occurred within 24 hours of administration of an abciximab. This is distinct from all other types of drug-induced thrombocytopenia, which requires a period of drug administration to induce sensitization. If APT occurs and is left untreated, it can cause serious hemorrhage and ischemia that may be fatal. In this case, a 45-year-old man with acute myocardial infarction was administered a bolus intravenous injection of abciximab (0.25 mg/kg), followed by a 12-hour continuous infusion (10 microgram/min) during primary coronary angioplasty. We report a case of APT that was recognized at 2 hours after the initiation of abciximab infusion and was corrected without serious complications.

OBJECTIVES: This study aimed to estimate the optimal cut-off score on Korean version of Mini-Mental State Examination (MMSE-K) for screening of dementia in community dwelling old people, and to investigate possible changes of the cut-off score according to age, gender, educational level, living area, and depression of the old people. METHODS: For the old people aged 65 or over dwelling in two areas of Kwangju, cognitive function (MMSE-K) and demographic characteristics (age, gender, educational level, living area) were investigated. For those scoring 24 or less on MMSE-K of them, clinical diagnosis of dementia (DSM-IV) and depression (Hamilton Rating Scale for Depression) were assessed. The optimal cut-off score on MMSE-K with a sensitivity and a specificity was examined by using receiver operating characteristics curve analysis served by diagnosis of dementia as a gold standard. Associations of the cut-off score on MMSE-K with demographic characteristics and depression were estimated by odds ratios. For those factors showing significant association with cut-off score on MMSE-K regardless of the diagnosis of dementia, the optimal cut-off scores on MMSE-K were measured again at each level. RESULTS: In the old people scoring 24 or less on MMSE-K (n=341), the optimal cut-off score on MMSE-K served by diagnosis of dementia was 21/22 with a sensitivity of 81% and a specificity of 64%. Only the age among the investigated characteristics was significantly associated with the cut-off score on MMSE-K, and the optimal cut-off score in those aged 75 or over was revealed to be 20/21. CONCLUSIONS: We suggest that the cut-off score on MMSE-K for screening of dementia investigated in this study could be used by community health care staff as a guideline for assessing old people with questionable cognitive dysfunction or for considering to consult them to an expert.
