Isoniazid(Isonicotinic acid hydrazide) is an antimicrobial drug used since 1952 as a fast line agent for the prophylaxis and treatment of tuberculosis. Isoniazid is well known for problems in population having a high prevalence of isoniazid use for prophylaxis or treatment of tuberculosis. But intentional or accidental isoniazid overdose is uncommon. The ingestion of toxic amounts of isoniazid causes recurrent seizures, profound metabolic acidosis, coma and even death. In adults, toxicity can occur with the acute ingestion of as little as 1.5g of isoniazid. Doses larder than 30mg per kg often produce seizures. When ingested in amounts of 80-150mg per kg or more, isoniazid can be rapid fatal. 40-year-old woman having previous pulmonary tuberculosis ingested 7 gram of isoniazid(140mg/kg) to attempt suicide approximately 30 minutes prior to visit to our emergency medical center. She had recurrent generalized tonicclonic seizures and metabolic acidosis. We report one patient treated with pyridoxine, which was equivalent to the amount of isoniazid ingested and administered as a intravenous dose and oral dose.

BACKGROUND: Flood is the most common natural disaster in our country. Lots of victims occurred during the period of flood in the northern territory of Kyoungkido on August 5, 1998. We tried to describe the characteristics of the flood-related injury and illness, management and medical requirements. METHODS: We interviewed the patients admitted to 8 hospitals in Ujungbu and reviewed medical records from aug 5 to Aug 14, 1998. RESULTS: There were total 102 patients, male were 52%and women were 48% Most of patients were between 30's and 60's. Most of them were minor, and less than 3%of them needed critical care. The diagnosis were laceration(39.2%, contusion(22.5%, fracture(13.7%, infectious disease(7.8%, ligament rupture(7.8%, aggravation of chronic illness(5.9%, dermatitis(2.0% and traumatic hyphema(1.0%. The laceration occurred in the foot(37.9%, lower leg(27.0%, thigh(16.2%, hand(10.8% and head(8.1%. The location of ligament injury were achilless tendon(62.5%, hand(25% and knee(12.5%. The 67.5%of flood-related laceration patients progressed cellulitis, especially in sutured wound and a typical tetanic patient was developed. Of hospitalized patients, 2 patients showed evidence of post-traumatic stress disorder(PTSD). CONCLUSION: During flood, civils have better to be educated about prevention of injury, such as wearing of shoes and clothes. Although laceration was minor, lacerated wounds should be thoroughly irrigated, debrided the margin and considered delayed closure, tetanus immunization. Reportedly, there is an increased prevalance of PTSD and depression after disasters. Therefore mental health care will be required in the future.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential far abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. the onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-l0g. We describe an 23-year-old woman with pulmonary edema and cardiac arrest after ingestion of 18 grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and hemoperfusion. We report a case with literature review.

BACKGROUND: One of the most frequent cytogenetic abnormality in acute myeloid leukemia (AML) is t(8;21) (q22;q22), with rearrangement of the AML1 gene on chromosome 21q22 and the ETO gene on chromosome 8q22. In adult AML1/ETO-associated leukemia patients, chemotherapy alone results in cure rates that are comparable to or better than those achieved with allogenic bone marrow transplantation. Despite the relatively good prognosis of AML1/ETO fusion transcript, relapse of leukemia remains the most common cause of treatment failure. Monitoring minimal residual disease (MRD) in leukemia has two main aims : to assess the effectiveness of treatment and to detect early signs of relapse. Reverse transcription-polymerase chain reaction (RT-PCR)- based methods is the rapid and sensitive method in the identification of this molecular abnormality. The purpose of this study is to ensure the usefulness of the RT-PCR technique for detecting MRD in AML1/ETO-associated leukemia patients in remission and to establish the correlation of the serial detection of AML1/ETO fusion transcripts after complete remission and long-term outcome. METHODS: From the bone marrow aspirates of 25 AML1/ETO positive AML patients, serial detection of AML1/ETO fusion trascripts was performed using RT-PCR. RESULTS: AML1/ETO fusion transcripts were positive in 14 cases who did not show t(8;21). In serial assay, AML1/ETO fusion transcripts was positive in 9 cases and negative in 13 cases at 10 weeks after complete remission. AML1/ETO fusion transcripts (+) group has 107.4+/-18.2 months suvival and AML1/ETO fusion transcripts (-) group has 47.3+/-18.0 months survival. However, there is no significance (P=0.11). CONCLUSION: This study suggests that the early negative conversion of AML1/ETO fusion transcript may be the good prognostic predictor. The RT-PCR technique is useful for detecting minimal residual disease in leukemia patients in remission and it may improve the therapeutic strategy for leukemia.

Regular exercise training improves body composition, blood lipid profiles and exercise adaptation. This study was conducted to investigate the effect of exercise training at different times of day on body composition, blood lipids, stress hormones and nutrient intakes. Twenty four male graduate students carried out this experiment. The subjects were divided into three groups; morning exercise group, evening exercise group and control group. Two exercise groups performed running and muscular resistance training at mid intensity for 12 week periods. Body composition, blood lipid profiles, blood cortisol, ACTH and nutrient intakes were analyzed prior to, midway and after training. There were significant differences about interaction between different exercise times and training periods in plasma TG and HDL-C of the evening exercise training (p < 0.05). Also the evening exercise group was showed the decreasing of TC after training (p < 0.05). No significant differences about interaction between different exercise times and training periods were shown in body composition, stress hormones and nutrient intakes in the three groups. But evening exercise training decreased body fat (%) and blood ACTH (p < 0.05). Also the increasing of carbohydrate intakes was shown by the evening exercise training (p < 0.05). In contrast, morning exercise group indicated a decrease of body fat (%) after 6 week training (p < 0.05), but this effect was not maintained after 12 weeks of training. These results suggested that regular evening exercise is more effect than morning exercise from the viewpoint of improving body composition, blood lipids, nutrient intakes and exercise adaptation.

OBJECTIVES: Blood pressure variation (BPV) and metabolic syndrome is an independent risk factor for cardiovascular events. Ambulatory blood Pressure (ABP) has been shown to be more closely related to cardiovascular events in hypertensive patients than conventional office BP (OBP). Using both OBP and ABP, 4 groups of patients were identified: (1) normotensive patients (NT); (2) white coat hypertensives (WCHT); (3) masked hypertensives (MHT); and (4) sustainedhypertensives (SHT). We investigated the significance of BPV and metabolic risks of these 4 groups. METHODS: This study is a retrospective analysis of patients between January 2008 and May 2013. Echocardiography and 24 hour ABP monitoring were performed. RESULTS: BMI was significantly higher in the MHT compared with the NT. There were progressive increases in fasting glucose level from NT to WCHT, MHT, and SHT.MHT and SHT had higher 24h and nighttime BPV than NT.MHT was significantly related with BMI (r = 0.139, P = 0.010), creatinine (r = 0.144, P = 0.018), fasting glucose (r = 0.128, P = 0.046), daytime systolic BPV (r = 0.130, P = 0.017), and daytime diastolic BPV (r = 0.130, P = 0.017). Dyslipidemia (r = 0.110, P = 0.043), nighttime systolic BPV (r = 0.241, P < 0.001) and nighttime diastolic BPV (r = 0.143, P = 0.009) shown correlation with SHT. In multivariate logistic regression, MHT was independently associated with Body mass index (OR 1.086, 95% CI 1.005–1.174, P = 0.038) and creatinine (OR 1.005, 95% CI 1.001–1.010, P = 0.045). CONCLUSIONS: BPV and metabolic risk factors were found to be greater in MHT and SHT compared with NT and WCHT. This suggests that BPV and metabolic risks may contribute to the elevated cardiovascular risk observed in patients with MHT and SHT.

OBJECTIVES: Protein-calorie malnutrition has been shown to be prevalent among patients on chronic dialysis, And assessment of nutritional status of continuous ambulatory peritoneal dialysis(CAPD) patients has assumed greater importance because of the association of protein-calorie malnutrition with increasing morbidity and mortality. So we observed the incidence and clinical effect of protein-calorie malnutrition, and we compared the indices of nutrition with dialysis adequacy utilizing urea kinetic modeling and cretinine clearance in CAPD patients. METHODS: We performed a cross-sectional study in which eight parameters, based on anthropometry, blood chemistry and subjective symptoms, were scored according to the degree of abnormalities in 82CAPD patients. A malnutrition index was derived from these scores. We also performed comparative analysis to identify significant correlations of the indices of urea kinetic modeling and creatinine clearance with the other parameters of nutritional status. RESULTS: The malnutrition index classified 47(57%) patients as normal, 30(37%) intermediately malnourished, and 5(6%) as severely malnourished. Malnutrition index showed a significant correlation with the body mass index(BMI), triceps skinfold thickness(TSF), mid-arm circumference(MAC), mid-arm muscle area (MAMA), duration of CAPD, subjective symptoms, serum albumin, transferrin, cholesterol, and triglyceride. The malnutrition index also showed a significant correlation with residual renal function(RRF), and standardized creatinine clearance(SCCr). The TWR-Kt/V(total Kt/Vurea per week with consideration of residual renal urea clearance) was significantly lower in the severely malnourished group than in the normal group. Serum alkaline phosphatase and BUN levels were higher in the severely malnourished group than in the normal and inter-mediate groups. CONCLUSION: In assessing the nutrition status of CAPD patients, body weight, TSF, MAC, MAMA, subjective symptoms, serum albumin, transferrin, cholesterol, triglyceride, urea nitrogen, and alkaline phosphatase were considered useful parameters. There was a trend of increased BUN and decreased TWR-Kt/V in severely malnourished patients, and the value of SCCr was significantly lower in malnourished patients. However, no meaningful relationships between TW-Kt/V and malnutrition index or between NPCR(normalized protein catabolic rate) and malnutrition index were found m this cross-sectional study. As the number of patients with longer duration of CAPD or negligible RRF has increased in the malnourished patients, regular monitoring of these parameters, especially TWR-Kt/V and SCCr, may be helpful to assess dialysis adequacy to keep good nutritional status of each CAPD patient.

The highly toxic sodium monofluoroacetate (SMFA) was banned as a rodenticide in this country in the 1980s. The fluoroacetate metabolite, fluorocitric acid blocks cellular metabolism by inhibiting the Klebs cycle, producing widespread clinical effects including respiratory, neurologic, cardiologic, and fluid-electrolyte abnormalities. We report the case of intentional ingestion of a derivative product, beta-fluoroethyl acetate. A 79-yr-old female was brought to the emergency room without any problem. At 2hours post ingestion, she had a generalized tonic-clonic seizure and then, was unresponsive to painful stimuli. At 6hours post ingestion, she died from refractory ventricular fibrillation. We report this patient to increase awareness of beta-fluoroethylacetate toxicity.

OBJECTIVE: Accelerometer is a convenient device that can easily measure human movement. The purpose of this study was to evaluate its usefulness in the assessment of hemiparetic gait after stroke. METHOD: Twenty hemiparetic stroke patients were enrolled in the study. A portable accelerometer was attached between L3,4 intervertebral area. Vertical and medio-lateral acceleration was measured while walking 10 m. Walking ability of each subject was classified by Functional Walking Category (FWC). RESULTS: Accelerometric parameters, such as walking speed, a mean amount of peak vertical acceleration in one gait cycle, mean peak value of unaffected side, peak vertical acceleration ratio, step time ratio were significantly higher in groups of FWC 4, 5, 6 than in groups of FWC 2, 3. In subjects using cane there was an extra peak other than peaks observed in non-users. Mean peak value, step length of unaffected side and cadence were significantly higher in non-users than in users. CONCLUSION: Trunk accelerometer can be used as an objective method to evaluate walking ability in hemiparetic patients after stroke.

Purpose: Differentiating between glioblastoma and solitary metastasis is very important for the planning of further workup and treatment. We assessed the ability of various morphological parameters using conventional MRI and diffusion-based techniques to distinguish between glioblastomas and solitary metastases in tumoral and peritumoral regions. Materials and Methods: We included 38 patients with solitary brain tumors (21 glioblastomas, 17 solitary metastases). To find out if there were differences in the morphologic parameters of enhancing tumors, we analyzed their shape, margins, and enhancement patterns on postcontrast T1-weighted images. During analyses of peritumoral regions, we assessed the extent of peritumoral non-enhancing lesion on T2- and postcontrast T1-weighted images. We also aimed to detect peritumoral neoplastic cell infiltration by visual assessment of T2-weighted and diffusionbased images, including DWI, ADC maps, and exponential DWI, and evaluated which sequence depicted peritumoral neoplastic cell infiltration most clearly. Results: The shapes, margins, and enhancement patterns of tumors all significantly differentiated glioblastomas from metastases. Glioblastomas had an irregular shape, ill-defined margins, and a heterogeneous enhancement pattern; on the other hand, metastases had an ovoid or round shape, well-defined margins, and homogeneous enhancement. Metastases had significantly more extensive peritumoral T2 high signal intensity than glioblastomas had. In visual assessment of peritumoral neoplastic cell infiltration using T2-weighted and diffusion-based images, all sequences differed significantly between the two groups. Exponential DWI had the highest sensitivity for the diagnosis of both glioblastoma (100%) and metastasis (70.6%). A combination of exponential DWI and ADC maps was optimal for the depiction of peritumoral neoplastic cell infiltration in glioblastoma. Conclusion In the differentiation of glioblastoma from solitary metastatic lesions, visual morphologic assessment of tumoral and peritumoral regions using conventional MRI and diffusion-based techniques can also offer diagnostic information.
