Spontaneous rupture of the renal pelvis or ureteropelvic juction area with extravasation of urine into the perinephric space is an uncommon pathologic condition (1). We report a case of 72-year-old woman who suffered 2 days of left loin pain. The patient has got residual urine sensation and weak urine stream since she has gone through a radical hysterectomy 17 years before. Because of these symptoms of voiding difficulty, the patient had abdominal straining during her urination. A CT scan exhibited renal pelvis rupture with perirenal extravasation of urine due to severe hydronephrosis, that was exacerbated by hidden neurogenic bladder disease. Moreover, the patient has detrusor underactivity and high intravesical pressure at voiding trial in the urodynamic study. One month after the percutaneous nephrostomy insertion into the left renal pelvis, the patient was successfully treated. The size of renal pelvis decreased. Moreover, urinoma disappeared in follow up CT scan image.

OBJECTIVE: A Comparison of QTc prolongation for various antipsychotics and an analysis of QTc prolongation for the various types of serotonin transporter polymorphism were performed. METHOD: EKG was checked, followed by QTc measurement as Bazett's correction, and the serotonin transporter polymorphism was examined in 110 chronic schizophrenia patients were performed EKG before 24 weeks ago. We defiened QTc prolongation as over 450ms. The risk factor of sudden cardiac death were defiend as QTc prolongation and or 60ms in delta value. RESULT: The prevalence of QTc prolongation in this study was 7.3%, and the prevalence of over 60ms was 4.5%. Patients who had the risk factors were 10(9.1%). 6/52 who prescribed atypical antipsychotics and 2/58 who prescribed haloperidol showed QTc prolongation. The prevalence who had the risk factor of sudden cardiac death were 16% in atypical antipsychotics group, 3.4% in haloperidol group. QTc prolongation were observed more frequently in l/l type than s/s type. l allele frequency were 50% in QTc prolongated group, 19% in not prolongated group. l allele had an association with QTc prolongation(p<0.01). CONCLUSION: The prevalence of QTc prolongatin was frequent in chronic schizophrenia patients who were prescribed atypical antipsychotics. It has strong association with l allele of 5-HTTLPR.

This study was done to identify the normal and variants of saphenous tributaries in Korean adults. The pattern of confluence of saphenous tributaries, medial accessory saphenous, lateral accessory saphenous, superficial epigastric, superficial circumflex iliac and superficial external pudendal veins, was carefully examined in 249 lower limbs (right, 129; left, 120) of embalmed Korean cadavers (73 males and 56 females). The medial accessory saphenous vein drained into the great saphenous vein directly (in 82.3%) or by a common trunk (in 17.7%) with the superficial epigastric or superficial external pudendal vein. The lateral accessory saphenous vein entered the great saphenous (in 67.1%) or the femoral vein (in 32.9%) directly or, forming a common trunk with other saphenous tributaries. The superficial epigastric vein joined the great saphenous (in 77.1%) or the femoral vein (in 22.9%) directly or, by a common trunk with other saphenous tributaries. The superficial circumflex iliac vein reached the great saphenous (in 83.1%) or the femoral vein (in 16.9%) directly or, by a common trunk with other saphenous tributaries. The superficial external pudendal vein opened into the great saphenous (in 95.2%) or the femoral vein (in 4.8%) directly or by a common trunk with other saphenous tributaries. In Koreans, the incidence of the normal pattern of saphenous tributaries was 23.7% and in 76.3% any one of variant saphenous tributaries entered the femoral or the great saphenous vein by a common trunk with other saphenous tributaries.

OBJECTIVE: Although atypical antipsychotics are increasingly being used as monotherapy in acute mania, few Korean studies have investigated on them. This study evaluated the efficacy and tolerability of olanzapine monotherapy in patients with acute mania. METHODS: This multicenter, open-label study evaluated the efficacy of olanzapine to treat mania over 6 weeks. Patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were treated with olanzapine (flexible dosage to a maximum of 30 mg/day). Clinical improvements were rated using the Young Mania Rating Scale (YMRS), Clinical Global Impression-Bipolar Version (CGI-BP), Brief Psychiatric Rating Scale (BPRS), and the Montgomery-Asberg Depression Rating Scale (MADRS). Adverse events were measured using the Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS). The general functioning of patients was assessed using the Global Assessment Scale (GAS). All assessments were carried out at baseline and at days 7, 14, 21, and 42, with the exception of the GAS. RESULTS: The subjects comprised 76 patients (male=38, female=38), with 55 patients (72.4%) completing the study. The mean initial dose of olanzapine was 11.7+/-5.0 mg/day and mean daily doses at days 7, 14, 21, and 42 were 16.6+/-5.2, 17.2+/-5.0, 18.1+/-5.3, and 17.4+/-4.7 mg/day, respectively. At days 7, 14, 21, and 42, YMRS, CGI-BP, MADRS and BPRS scores had significantly improved from baseline. More improvement in MADRS scores was observed among patients with mixed mania than patients with euphoric mania. Changes in BPRS scores from baseline did not differ between patients with psychotic symptoms and those with euphoric mania. At days 21 and 42, 42 (55.3%) and 57 (75.0%) patients had responded (YMRS scores decreased from baseline by more than 50%). Also 27 (35.5%) and 46 (60.5%) patients had achieved remission (YMRS scores < or =12) at the same assessment points. GAS scores at days 21 and 42 indicated that olanzapine monotherapy improved patients' global functioning compared to baseline. SARS and BARS scores did not differ significantly between pre- and post-drug trial. CONCLUSION: The data indicate that olanzapine monotherapy has favorable effects across a broad range of mood symptoms and yields functional improvement in acute manic patients with minimal adverse events. Therefore, olanzapine monotherapy may be a preferred first-line agent to treat patients with acute mania. These results support the findings from previous studies and guidelines.

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.

OBJECTIVE: Recently, the atypical antipsychotics such as quetiapine, olanzapine, risperidone, aripiprazole and ziprasidone are increasingly used in the management of acute manic patients as the monotherapy. But there are only a few reports on the use of these drugs in the treatment of bipolar disorder in Korea. The aim of this study was to evaluate the efficacy and tolerability of quetiapine monotherapy in patients with acute mania. METHOD: This study is multi-center, open-label, 6-week evaluation of the efficacy of quetiapine in bipolar mania. In this study, patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were included to treatment with quetiapine (flexibly dosed up to 800 mg/day). Clinical improvements were rated by Young Mania Rating Scale (YMRS), Clinical Global Impression-Bipolar Version (CGI-BP), Brief Psychiatric Rating Scale (BPRS) and Montgomery-Asberg Depression Rating Scale (MADRS). Adverse events were measured using Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS), and subjective reports of patients were evaluated. Global Assessment Scale (GAS) was used to evaluate the general functioning of patients. All assessments were done at baseline and at days 7, 14, 21, and 42 except GAS (at days 21 and 42). Analyses were focused on change from baseline to day 42. RESULTS: Total 78 (male=30, female=48) patients were included and 59 patients (75.6%) completed the study. The mean initial dose of quetiapine was 268.0+/-223.2 mg/day and mean daily dose at day 42 was 585.3+/-244.5 mg/day. YMRS and CGI-BP were significantly improved at day 7, 14, 21, and 42 as compared to baseline. Mean scores of BPRS and MADRS were also significantly decreased at the each assessment points. Fifty-two patients (66.7%) showed response (more than 50% of decrease in YMRS score from baseline) and 35 patients (44.6%) reached remission (YMRS score < or =12) at day 21. GAS showed the improvements of patient's global functioning at days 21 and 42 of quetiapine monotherapy compared to baseline. There was no significant difference between baseline and any assessment points on SARS and BARS scores. CONCLUSIONS: The data showed that quetiapine monotherapy has favorable effects across a broad range of mood symptoms with minimal adverse events in addition to functional improvement in acute manic patients. This result suggests that quetiapine may be preferred for patients with acute mania as one of the first-line agents.

BACKGROUND: The nutritional status of critical-ill patients is important for recovering from the disease itself. Therefore, this present study was designed to assess the biochemical and nutritional parameters of Intensive-Care Unit (ICU) patients on mechanical ventilation. METHODS: We retrospectively reviewed the medicial records of 126 patients (male/female=72/54) who were on mechanical ventilationin the ICU. The nutritional parameters such as serum total protein, albumin, hemoglobin, hematocrit, calcium, phosphorus, total cholesterol, % lymphocytes, blood urea nitrogen (BUN), and creatinine (Cr) were measured at the beginning of mechanical ventilation. We also measured the outcome variables such as the duration of mechanical ventilation, the ICU length of stay and the hospitalization period. We analyzed the relationship between the nutritional parameters and the outcome variables of ICU patients on mechanical ventilation. RESULTS: The level of hemoglobin was negatively correlated with the outcome variables; the ICU length of stay (p<0.05), the hospitalized period (p<0.01), and the duration of mechanical ventilation (p<0.01). The creatinine level was positively correlated with the outcome variables; the ICU length of stay (p<0.01), the hospitalized period (p<0.01) and the duration of mechanical ventilation (p<0.05). On the multiple regression analysis, the serum total protein, albumin, calcium, inorganic phosphorus, BUN and creatinine were independent factors affecting the duration of mechanical ventilation. CONCLUSIONS: These findings indicate that ICU patients with mechanical ventilation have a risk for malnutrition and anemia. So, an adequate nutritional intervention is required for these patients in order to decrease the prevalence of malnutrition and anemia.

Renal lipomas are among the rearest of renal tumors. They probably originate from fat cells within renal capsule or parenchyma. The tumors are confined within renal capsule, in contrast to the perirenal lipomas, which are extracapsular. We recently encountered a case of renal lipoma with bladder stone and diabetes mellitus in 61 years old male patient.

BACKGROUND: The ratio of the steady-state 24-hour area under the concentration-time curve (ssAUC24) to the MIC (AUC24/MIC) for vancomycin has been recommended as the preferred pharmacodynamic index. The aim of this study was to assess whether the calculated AUC24 (cAUC24) using the creatinine clearance (CLcr) differs from the ssAUC24 based on the individual pharmacokinetic data estimated by a commercial software. MATERIALS AND METHODS: The cAUC24 was compared with the ssAUC24 with respect to age, body mass index, and trough concentration of vancomycin and the results were expressed as median and interquartile ranges. A correlation between the cAUC24 and ssAUC24 and the trough concentration of vancomycin was evaluated. The probability of reaching an AUC24/MIC of 400 or higher was compared between the cAUC24 and ssAUC24 for different MICs of vancomycin and different daily doses by simulation in a subgroup with a trough concentration of 10 mg/L and higher. RESULTS: The cAUC24 was significantly lower than the ssAUC24 (392.38 vs. 418.32 mg.hr/L, P < 0.0001) and correlated weakly with the trough concentration (r = 0.649 vs. r = 0.964). Assuming a MIC of 1.0 mg/L, the probability of reaching the value of 400 or higher was 77.5% for the cAUC24/MIC and 100% for the ssAUC24/MIC in patients with a trough concentration of 10 mg/L and higher. If the MIC increased to 2.0 mg/L, the probability was 57.7% for the cAUC24/MIC and 71.8% for the ssAUC24/MIC at a daily vancomycin dose of 4,000 mg. CONCLUSIONS: The cAUC24 using the calculated CLcr is usually underestimated compared with the ssAUC24 based on individual pharmacokinetic data. Therefore, to obtain a more accurate AUC24, therapeutic monitoring of vancomycin rather than a simple calculation based on the CLcr should be performed, and a more accurate biomarker for renal function is needed.

OBJECTIVE: The purpose of the present study was to investigate the efficacy, safety, and tolerability of aripiprazole in patients with schizophrenia, schizophreniform disorder, and schizoaffective disorder during acute treatment phase. METHODS: Prospective, multicenter, single group, and 8-week study was conducted in patients with schizophrenia, schizophreniform disorder, and schizoaffective disorder. A total of 300 patients were enrolled in the present study. The primary efficacy measure was the Positive and Negative Syndrome Scale (PANSS) total score, and secondary efficacy measures were the PANSS positive and negative subscales scores, and Clinical Global Impression-Severity of Illness (CGI-S) score. Treatment-emergent adverse events, extrapyramidal symptoms (EPS), weight, vital signs, and laboratory tests were assessed as measures of tolerability and safety. RESULTS: Significant improvements in all efficacy measures were achieved by aripiprazole as early as 1-week and sustained through 8-week period. First-episode patients showed greater improvements in PANSS total, positive subscale score, and CGI-S score, compared with recurrent patients. Slightly increased akathisia (+0.32 from baseline score of Barnes Akathisia Rating Scale, p=0.033) and weight gain (1.15+/-3.44 kg, p<0.001) were observed by aripiprazole during 8-week acute treatment phase. CONCLUSION: The present study demonstrated that aripiprazole was effective in acute treatment of positive and negative symptoms of schizophrenia, schizophreniform disorder, and schizoaffective disorder. In general, aripiprazole showed favorable safety and tolerability profiles, although clinicians needed to pay attention to the possibility of akathisia and weight gain by aripiprazole in first-episode patients during acute treatment phase.
