PURPOSE: The objective of this study was to evaluate the advantages of a laparoscopic technique for the treatment of intussusception in children with repeated hydrostatic reduction failure. METHODS: Between April 2001 and March 2002, twenty one children with intussusception were treated. Eleven patients, with repeated barium reduction failure, underwent a laparoscopic reduction. The type of intussusception, operative time, postoperative hospital stay, and conversion rate, were prospectively examined. RESULTS: The laparoscopic reduction was successful in 8 patients (72.7%), with a conversion to an open procedure occurring in 3 (27.3%). In the 8 successful laparoscopic reduction cases, the average operative time and postoperative hospital stay were 66 minutes and 3 days, respectively. Seven cases were of the ileo-colic type of intussusception and remaining one was of the ileo-ileo-colic type. There were no mortalities or intraoperative complications. CONCLUSION: Intussusception in number of children with hydrostatic reduction failure could be reduced with the laparoscopic technique. The laparoscopic procedure for intussusception was safe and resulted in the avoidance of open surgery.

PURPOSE: The aim of this study is to determine whether a difference in the amount of bone graft material is needed between edentulous patients and dentulous patients and to calculate the amount of augmentation for a sinus lift procedure. METHODS: 19 patients (20 sinuses) were included to measure maxillary sinus volume. Facial CT scanning was performed using MX 8000 IDT CT devices (Philips, USA). And it was used for IDLvm (The IDL Virtual Machine) 6.0, CT Volume Analyzer Ver 2.3 program to measure maxillary sinus volumes RESULTS: At edentulous patients, volumes (mean+/-SD) of the inferior portion of the sinuses were 0.56+/-0.13 cm3 (5mm height), 2.35+/-0.57 cm3 (10mm height), 4.85+/-1.10 cm3 (15mm height). At dentulous patients, volumes (mean+/-SD) of the inferior portion of the sinuses were 0.41+/-0.18 cm3 (5mm height), 1.76+/-0.42 cm3 (10mm height), 3.80+/-0.84 cm3 (15mm height). A significant correlation was found between augmentation height (5mm, 10mm, 15mm) and the calculated sinus volume. (p=0.027, p=0.018, p=0.044) CONCLUSIONS: A significant correlation was found between augmentation height (5mm, 10mm, 15mm) and the calculated sinus volume. Detailed preoperative knowledge of sinus lift augmentation volume is helpful in determining the appropriate amount of the bone graft material.

There are several oral lesions related with AIDS, such as candidiasis, hairy leukoplakia, Kaposi's sarcoma, aphthous stomatitis, lichen planus, and other opportunistic infectious diseases. Among the others, Kaposi's sarcoma, the most common malignant tumor associated with AIDS, is closely linked to the number of CD4+ T cell. Kaposi's sarcoma often occurs in palate, the most prone site, and has characteristic clinical features in most cases. Sometimes, the tumor induces underlying bone destruction at late stage. We report a case of a 27 year-old man with AIDS-associated Kaposi's sarcoma at left lower retromolar triangle, parapharyngeal area and discuss the management of AIDS patients in dentistry.

PURPOSE: This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fire that broke out at a bar in Incheon. METHOD: We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. RESULT: The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121 (89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. CONCLUSION: The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment (START) system and a reassessment the delayed category in fire disasters.

BACKGROUND: Isoniazid(INH) and rifampicin(RFP) are the most effective anti-tuberculosis drugs which make the short-course chemotherapy possible. Although prescribed dosages of INH and RFP in Korea are different from those recommended by American Thoracic Society, there has been few study about pharmacokinetic profiles of INH and RFP in Korean patients who receive INH, RFP, ethambutol(EMB) and pyrazinamide(PZA) simultaneously. METHODS: Among the patients with active tuberculosis from Dec. 1997 to July 1998, we selected 17 patients. After an overnight fast, patients were given INH 300mg, RFP 450mg, EMB800mg and PZA 1500mg daily. Blood samples for the measurement of plasma INH(n=15) and RFP(n=17) level were drawn each at 0, 0.5, 1, 1.5, 2, 4, 6, 8 and 12hrs, and urine was also collected. INH and RFP level in the plasma and the urine were measured by high-performance liquid chromatography(HPLC). Pharmacokinetic parameters such as peak serum concentration(Cmax), time to reach to peak serum concentration(Tmax), half-life, elimination rate constant(Ke), total body clearance(CLtot), nonreanl clearance(CLnr), and renal clearance(CLr) were calculated. RESULTS: 1) Pharmacokinetic parameters of INH were as follows: Cmax; 7.63 +/- 3.20 micro gram /ml, Tmax; 0.73 +/- 0.22hr, half-life;2.12 +/- 0.84hrs, Ke;0.83 +/- 0.15hrs-1, CLtot;17.54 +/- 8.89L/hr, CLnr; 14.74 +/- 8.35L/hr, CLr; 2.79 +/- 1.31L/hr 2) Pharmacokinetic parameters of RFP were as follows : Cmax; 8.93 +/- 3.98 micro gram/ml, Tmax;1.76 +/- 1.13hrs, half-life;2.27 +/- 0.54hrs, Ke;0.32 +/- 0.08hrs-1, CLtot;14.63 +/- 6.60L/hr, CLr;1.04 +/- 1.55L/hr, CLnr;13.59 +/- 6.21L/hr. 3) While the correlation between body weight and Cmax of INH was not statistically significant (gamma=-0.514, p value >0.05), Cmax of RFP was significantly affected by body weight of the patients(gamma=-0.662, p value <0.01). CONCLUSION: In Korean patients with tuberculosis, 300mg of INH will be sufficient to reach the ideal peak blood level even in the patients over 50kg of body weight. However, 450mg of RFP will not be the adequate dose in the patients who weigh over 50~60kg.
