We report a rare case of thrombosed developmental venous anomaly (DVA) in a 31-year old male with hemorrhagic cerebral venous infarction at the initial clinical presentation. In this case, sequential CT, CT angiography and digital subtraction angiography demonstrated thrombotic obstruction of the venous drainage from DVA, its progressive recanalization and temporal evolution of the affected brain parenchyma. The relevant previous literatures were reviewed and summarized.

With the introduction of dental implants, restoration of missing teeth with conventional fixed or removable partial dentures is being replaced with implants. Especially, with young patients, not only longevity but also esthetic factors need to be considered. Implant restorations provide long-term success functionally but, esthetic complications such as, marginal exposure due to gingival recession, loss of the papilla and dark color of metal abutments may occur. Recently, zirconia restorations with CAD/CAM technology provide functional, biocompatible and esthetic restorations possible. All-ceramic restorations using the pressed ceramic technique show better fracture toughness values than those of the conventional porcelain veneering technique. Pressed ceramic technique creates the veneer design in wax and the lost wax technique is used to create the restoration. The final contour of the restoration may be controlled during wax-up. A 22-year old female patient was restored with dental implants and zirconia restorations using the pressed ceramic technique presenting short-term but optimistic prognosis.

Thirty patients who had elective general anesthesia at Kyungpook National University Hospital from April to August 1986 were studied for intraocular pressure(lOP) changes after intravenous lidocaine administration. The resultg were as follows. The 30 patients comprised three groups of each 10, placebo group and lidocaine 1 mng/kg and 2mg/kg Pretreatment group. In lidocaine 1 mg/kg administration group, the IOP of 1 minute and 2 minutes after intubation were 21.8+/-3.8 mmHg, 21.3+/-2.6 mmHg and showed significant(p<0.01) increase compared with the control value. In lidocaine 2 mg/kg pretre-atment group, the IOP of I minute after intubation was 22.7+/-3.9 mmHg and showed significant(p70.05) increase, but the IOP of 2 minute after intubation was 20.2+/-3.2mmHg which not showed significant increase compared with the control value. The IOP of 2 minute after incubation in lidocaine 1 mg/kg administration group(p<0.05) and lidocaine 2 mg/kg administration group(p<0.01) showed significant decrease compared with placebo group. The incidence of coughing and arrhythmia stowed decreasing tendency according to doses of lidocaine, but not statistically significant.

A closing wedge distal femoral osteotomy is a procedure to reduce pain and delay the progression of degenerative arthritis of knee by moving the weight bearing line from the lateral compartment to the medial side while preserving the knee joint. Age, weight bearing line, and the degree of arthritis are the essential factors to be considered at the time of surgery. The indications for distal femoral osteotomy are as follows. All patients are aged less than 65 years old, normal medial compartment of the knee with normal patello femoral joint, valgus deformity with lateral degenerative arthritis, younger patients with lateral osteochondritis, congenital osteochondrosis, and recurrent patellar dislocation with genu valgum. The distal femoral osteotomy provides the advantages of rapid pain reduction and short rehabilitation in young and active patients and patients who are subjected to heavy loads on the knee.

PURPOSE: The anastomosis of hepatic artery to recipient vessel has a major role in a liver transplantation, so its occlusion is the most important cause of failure of liver transplantations. We made the study to reveal the peculiarities in pediatric liver transplantations compared with adult cases. METHODS: From January 1999 to September 2005, we performed 99 cases of pediatric liver transplantation. The mean age at operation was 4.17 years of age. The hepatic vein and portal vein are anastomosed by the general surgeons and then the hepatic artery is anastomosed by the plastic surgeons. The Doppler ultrasonography and computed tomography were used for postoperative checkup for hepatic artery patency. RESULTS: There were no immediate complications, but hepatic arterial occlusion was developed in 3 cases (2.8%). In pediatric patients, the anastomosis of hepatic artery is more difficult than adults because of the rapid respiratory and pulse rate, the small vascular diameter, and the large gap of diameter difference between the recipient and the donor vessels. CONCLUSION: We could confirm that pediatric liver transplantations are relatively safe but long learning curve was needed.

A 43-year-old male was admitted for reconstruction surgery to repair posterolateral rotatory instability of the knee. At the request of the surgeon, ranitidine was slowly administered intravenously immediately before the patient was transferred to the operating room to reduce the incidence of acid reflux. A few minutes later, during the transfer of the patient, anaphylaxis developed with hypotension, nausea, dyspnea, change in consciousness and urticaria. The patient had no previous history of any allergic tendency. After appropriate management, he recovered without complication. Following surgery, an allergic skin prick test was performed to determine if the patient was allergic to any of the drugs used during the surgery. According to the results, only ranitidine showed a positive reaction.

BACKGROUND AND OBJECTIVES: Imidapril, one of the ACE inhibitor, has been used to treate hypertension, congestive heart failure, diabetes mellitus and renal disease. ACE inhibitor, however often causes dry cough and this adverse effect affects the compliance rate negatively. This report aimed to examine the incidence rate of coughing caused by Imidapril treat-ment. And we compared the results with the incidence and tendency of dry cough caused by the other ACE inhibitors. MATERIALS AND METHOD: This study enrolled 38 patients who followed up at internal medicine and took Imidapril from the period of May 9, 1997 to December 17, 1997. We tested its effectiveness, safety and tolerance. The initial dosage of it was 5mg/day and the maximum dosage according to blood pressure was 10mg/day for 8 weeks. The tendency and the incidence of dry cough have been analyzed and compared with recently published Korean reports. RESULTS: The 5 mg dosage of Imidapril showed 68.1% in lowering blood pressure rate and it went up to 81.8% during the 8 weeks treatment perriod. The blood pressure regularity rate was 36.3% after the 8 weeks treatment. The overall rate of adverse effect occurrence was 26.1% (6/23) and 8.7% of them were likely to cough. One of the patients who showed nausea stopped medication. The recent articles reported that the incidence of dry cough had been reduced: Enalapril (33.8%), Fosinopril (16%), Ramipril (15%), Imidapril (7.8 - 8.7%), Losartan (4.3%). CONCLUSION: Imidapril is as safe and effective as other ACE inhibitors. Various ACE inhibitors that were newly developed show their effectiveness in lessening incidence rate of dry cough, and Imidapril is thought to be an excellent drug for this matter. Even though Losartan shows the lowest incidence rate of dry cough, it needs to more regular usages since it is still on the stage of its medical adaptation.

Because wide swings in temperature can occur during cardiac anesthesia all patients undergoing cardiac anesthesia should have their temperatures monitered. This is especially true in situations where deliberate hypothermia during cardiopulmonary surgery is an area of controversy. This study of 20 cases of open heart surgery was undertaken to compare the changes in tympanic membrane, nasopharyngeal, rectal and great toe temperatures and of to evaluate their correlation during the induction, cardiopulmonary bypass, rewarming and post-cardiopulmonary bypass periods. The temperature at each site was monitored every 10 minutes for 60 minutes of each period. The results were as follows, During the induction period, the temperature of the tympanic membrane, nasopharynx and rectum decreased significantly(p<0.05~p<0.01), but the temperatures of the great toe temperatures increased for 20 minutes and then slowly decreased during the next 30 to 60 minutes. During the cardiopulmonary bypass period, the sympanic membrane temperatures which were best correlated with the nasopharyngeal temperatures(p<0.05~p<0.01), decreased faster than the rectal, nasopharyngeal and great toe temperatures. During the rewarming period, the tympanic membrane temperatures increased most quickly and were significantly correlated with the nasopharyngeal temperatures(p<0.05) only at 0 and 10 minutes. During the post-cardiopulmonary bypass period, the tympanic membrane and nasopharyngeal temperatures decreased slowly and were significantly correlated with each other(p<0.01), but the rectal and the great toe temperatures increased slowly.

Short inversion time inversion recovery (STIR) is widely used for spinal magnetic resonance imaging (MRI) because the pulse sequence of STIR is insensitive to magnetic field inhomogeneity and can be used to scan a large field of view. In this case report, we present a case of spinal epidural hematoma with unexpected signal decrease on a STIR image. The MRI showed an epidural mass that appeared with high signal intensity on both T1- and T2-weighted images. However, a signal decrease was encountered on the STIR image. This nonspecific decrease of signal in tissue with a short T1 relaxation time that is similar to that of fat (i.e., hemorrhage) could lead to a diagnostic pitfall; one could falsely diagnose this decrease of signal as fat instead of hemorrhage. Awareness of the nonselective signal suppression achieved with STIR pulse sequences may avert an erroneous diagnosis in image interpretation.
