To evaluate appropriate diagnostic studies for renal infartion in emergency medical center, we analysed 33 patients of renal infarction treated in this hospital for last 8 years. Eleven patients, 4 trauma associated and 7 aortic disease associated patients were excluded. They are 11 males and 11 females with a mean age of 51 years. Fourteen came to the emergency medical center and seven came to the outpatient department, in the other one patient renal infarction was developed during hospitalization with other disease. On their past history they had hypertension in 9, valvular heart disease in 5, and diabetic mellitus in 4 patients. Abdominal or flank pain was noted in 17 of 22(77%). The other symptoms were vomiting, nausea, fever and so on. On microscopic examination of initial urine in hospital, 5 patients showed more than 10 red blood cells by high power field examination. The mean lactic dehydrogenase level was 1,239 I.U/L(normal range 218-472 I.U/L), while the mean aspartate aminotransferase and mean alanine aminotransferase were 51 I.U/L(normal range 13-36 I.U/L) and 44 I.U/L(normal range 5-33 I.U/L). Abdominal ultrasonography showed positive findings in 5 of 16(31%), of which 3 were confirmed by Doppler ultrasonography. In 18, computed tomography was done and all those showed positive findings of renal infarction(100%). In conclusion, it is important that identify the elevated lactic dehdrogenase level in case of any suspicion about renal infarction and confirm by computed tomography.

Background: The end-tidal carbon dioxide tension(ETCO₂) is defined as a partial pressure of carbon dioxide at the end of an exhaled breath. The purpose of this study is to determine the correlation between ETCO₂and arterial carbon dioxide tension(PaO₂) in nonintubated patients with respiratory distress in emergency department(ED). Methods: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO₂was measured with a capnography monitor during tidal volume breathing. ETCO₂were recoreded at the time of arterial blood gas sampling. The correlation between ETCO₂and PaCO₂was analyzed in all patients and in subgroups by simple linear regression. Results: Sixty patients were enrolled. In all patients, ETCO₂was 5.72mmHg lower than PaCO₂and correlated well with PaCO₂(r²=0.716). ETCO₂correlated best with PaCO₂in patients who were either acidotic or non-smoking. Conclusion: ETCO₂correlate well with PaCO₂in nonintubated patients with respiratory distress in ED. ETCO₂may be sufficient to reflect PaCO₂in selected patients and obviate the need for repeat arterial blood gas determination.

We reviewed 10 years experiences of the clinical aspects and early postoperative results in 544 pediatric patients(age less than 16 years old). Among them. 529 cases had the congenital heart diseases, and 15 had the acquired diseases. Open heart surgery was performed in 413 patients. 115 cases were treated with non-open heart surgery. 16 with interventional catheterization. Annual increase of the cardiac patients was not significant in recent 10 years, except slight increase in 1994. The mean age of the study patients had been evidently changed to younger year by year. Total mortality rate of the open heart surgery was 6.4%. The cyanotic congenital heart diseases were high in early postoperative mortality by 25.7%, whereas 4% in acyanotic group. The age group less than one month was most highest in surgical mortality(66.7%). There were no deaths in patients with patent ductus arteriosus(103 cases), atrial septal defect(83 cases) or pulmonary stenosis(17 cases). Among 220 patients with ventricular septal defects(VSD). 10(4.5%) were died early postoperatively. In cyanotic group, the patients with pulmonary atresia with ventricular septal defects(PAVSD), transposition of the great arteries(TGA), interrupted aortic arch(IAA), complex cardiac anomalies with isomerism seemed to be most susceptible to an early death.

Objective : To investgate patterns of serial serum interleukin-6(IL-6) concentrations after initial successful cardiopulmonary resuscitation, and to access differences in serum IL-6 concentrations in patients with Cerebral Performance Category(CPC, 1-2) and CPC(3-5) at the 5th day after cardiacpulmonary resuscitation(CPR). Methods : We studied prospectively 12 patients with spontaneous circulation after cardiopulmonary resuscitation. Venous blood samples were taken 2, 4, 12, 24, 48 and 72 hours after restoration of spontaneous circulation to measure serum IL-6 levels by the enzyme-linked immunosorbent assay. Results : Serum IL-6 concentrations in the severe neurolgically disabled group(CPC, 3-5) were significantly increased at 2, 24 and 48 hours after restoration of spontaneous circulation compared with the less neurolgically disabled group. Also, serum IL-6 concentrations in the severe neurolgic disabled group showed dual peak at 4 and 24 hours. Conclusion : Our study demonstrates significant increase of serum IL-6 in patients with CPC(3-5) after successful cardiopulmonary resuscitation and the significant correlation between early increase of serum IL-6 and poor neurologic outcome. It suggests that early increase of serum IL-6 can be used as a prognostic marker after successful cardiopulmonary resuscitation.

Rhabdomyolysis is a biochemical and clinical syndrome caused by lysis of skeletal muscle cell and release of muscle cell contents into the circulation. In addition to traumatic cause, various nontraumatic causes have been reported. Rhabdomyolysis has frequently been associated with seamy aspects of life and society: alcoholic abuse, drug addiction, sadistic drill exercise, war events and attempted suicide. The abuse of alcohol causes many hazards in many organs. One of these is acute alcoholic myopathy that may present as a fulminent syndrome of muscle pain and tenderness associated with rhabdomyolysis and acute renal failure. Because the prognosis of adequately treated rhabdomyolysis is excellent, early recognition and prompt management are essential in emergency situation. We experienced two typical cases of alcohol-induced rhabdomyolysis with acute renal failure and report these cases with literature review.

Background: Reperfusion of ischemic myocardium has been postulated to result in a specific oxygen radical mediated tissue injury. Iron may liberate during ischemia and we hypothesized that administration of the iron chelator, deferoxamine during ischemia would result in improved recovery after postischemic reperfusion. Purpose: To test whether iron-catalyzed processes contribute to myocardial necrosis during ischemia and reperfusion, deferoxamine was administered to block iron catalyzed hydroxyl radical formation in rabbits. Methods: Eleven rabbits were divided into two groups : control group (n=5) and deferoxamine pretreatment group (n=6). The left circumflex coronay artery was ligated for 30 minutes and reperfused for 180 minutes. Area at risk (AR) was measured by non-stained area with methylene blue injection into left atrium after left circumflex coronary artery ligation. Infarct size was measured by weighing after triphenyltetrazolium chloride staining. Heart rate was measured using electrocardiographic recording and systemic blood pressure was monitored by pressure transducer connected to the catheter in the left ventricle. Results: 1. There was no significant difference of heart rate and blood pressure in deferoxamine pretreatment group compared with control group. 2. There was significant decrease of serum iron concentration after continuous infusion of deferoxamine compared with serum iron concentration before ligation of coronary artery(P<0.05). 3. There was no significant difference of area at risk between control and deferoxamine pretreatment group. 4. Area at necrosis to area at risk was significantly reduced in deferoxamine pretreatment group compared with control group(P<0.05). The results suggest that deferoxamine infusion prior to coronary artery occlusion has a significant benefit in reducing infarct size in this model.

Material Properties and Compressibility Using Heckel and Kawakita Equation with Commonly Used Pharmaceutical Excipients

Choi, Du-Hyung,Kim, Nam-Ah,Chu, Kyung-Rok,Jung, Youn-Jung,Yoon, Jeong-Hyun,Jeong, Seong-Hoon The Korean Society of Pharmaceutical Sciences and 2010 Journal of Pharmaceutical Investigation Vol.40 No.4

This study investigated basic material properties and compressibility of commonly used pharmaceutical excipients. Five classes of excipients are selected including starch, lactose, calcium phosphate, microcrystalline cellulose (MCC), and povidone. The compressibility was evaluated using compression parameters derived from Heckel and Kawakita equation. The Heckel plot for lactose and dicalcium phosphate showed almost linear relationship. However, for MCC and povidone, curves in the initial phase of compression were observed followed by linear regions. The initial curve was considered as particle rearrangement and fragmentation and then plastic deformation at the later stages of the compression cycle. The Kawakita equation showed MCC exhibited higher compressibility, followed by povidone, lactose, and calcium phosphate. MCC undergoes significant plastic deformation during compression bringing an extremely large surface area into close contact and facilitating hydrogen bond formation between the plastically deformed, adjacent cellulose particles. Lactose compacts are consolidated by both plastic deformation and fragmentation, but to a larger extent by fragmentation. Calcium phosphate has poor binding properties because of its brittle nature. When formulating tablets, selection of suitable pharmaceutical excipients is very important and they need to have good compression properties with decent powder flowability. Material properties tested in this study might give a good guide how to select excipients for tablet formulations and help the formulation scientists design the optimum ones.
