BACKGROUND AND OBJECTIVES: The Oriental herbal materials known as aconitine have long been used in oriental traditional medicine for their analgesic and antiinflammatory effects. Aconitine and its related alkaloids are known cardiotoxins with no therapeutic role in modern western medicine. We have studied the cardiovascular side effects of intoxication that took place in otherwise healthy individuals after ingestion of herbal decoctions containing aconite alkaloids. MATERIALS AND METHOD: During a six-year interval from 1990 to 1996, 9 cases of accidental herb-induced aconitine intoxication were managed in Kyung Hee university medical center. Hospital records were reviewed in detail. RESULTS: All patients developed symptoms of aconitine toxicity within 4 hours of herb ingestion. The frequency of the order in cardinal symptoms of acute aconitine poisoning was nausea or vomiting, irritability, chest discomfort, dizziness, etc. Nine patients developed arrhythmias, including multifocal APC with aberrancy, multifocal VPC, ventricular tachycardia, etc. Administration of isotonic saline, dopamine, atropine and lidocaine with supportive cares brought clinical recovery and disappearance of arrhythmias in most cases within several hours. However, one case of acute aconitine poisoning had been dead of cardiac arrest due to ventricular fibrillation. CONCLUSION: Aconitine and its related alkaloids can cause toxic effects and even fatal poisoning. These cases point to the need for strict surveillance of herbal substances with low safety margins.

A study on changes of serum HDL-cholesterol level in various diseased states was performed. Diseased groups were nephrotic syndrome, liver cirrhosis, hyperthyroidism, hypothyroidism and chronic alcoholism. Following results were obtained. 1) Compared to normal control group, levels of HDL-cholesterol in nephrotic syndrome were lower but the difference was significant statistically. 2) In liver cirrhosis, the result showed much lower levels than normal control group with high significance. 3) In both hyper-and hypothyroidism group, the levels of HDL-cholesterol were significantly lower than normal control group. 4) In chronic alcoholism, the levels were significantly higher than normal control group. 5) Except for the group of chronic alcoholism, the levels of HDL- cholesterol were higher in female groups than male groups, but was of no significance statistically.

In order to determine the electrophysiologic properties of aberrant ventricular conduction we analyzed the electrophysiologic studies done for various reasons in SNUH(1983.3 -1987.8). All patients did not have underlying heart disease and were in sinus rhythm with normal PR intervals & no intraventricular conduction delay at the time of study. The patients of preexcitation syndrome were excluded. Only aberrant ventricular conduction induced by premature atrial stimulation at the high right atrium or(HRA) during sinus rhythm or HRA pacing was analyzed. 1) Aberrant ventricular conuction was induced by premature atrial extrastimulation in 34 subjects of 156 cases reviewed(21.8%). The patients were 16 to 70 years old(sixteen males and eighteen females). 2) The longest atrial coupling(A1S2) interval resulting in aberrant ventricular conduction approximated 45%(600-280) of the basic cycle length(450-1550 msec). 3) As a prerequisite for aberrant ventricular conduction, the functional refractory period(FRP) of the AV node should be less than the relative refractory period(RRP) of the His Purkinje System and the most important determinant of aberrant ventricular conduction by atrial extreastimulation was resultant H1H2 interval, which should be between RRP and effective refractory period(ERP) of HPS. 4) There was good linear correlation between the basic cycle length(BCL) and RRP of the HPS(RRP=0.247xBCL+247.048, r=0.885, p-value<0.001). 5) 155 different configurations of aberrant ventricular conduction were recorded during atrial extrastimulation till atrial ERP. The pattern frequencies were as follows : left anterior hemiblock, 6(3.9%) ; right bundle brach block, 92(59.4%) ; left bundle branch block, 28(18.0%) ; left anterior hemiblock combined with right bundle branch block, 14(9.0%) ; left posterior hemiblock combined with right bundle branch block, 9(5.8%) ; unclassified intraventricular conduction disturbances, 6(3.9%). 6) As the atrial coupling intervals were further shortened, aberrant conduction persisted up to the point of atrial ERP at 19/41 BCL's(46.3%). Other patterns of atrioventricular conduction were as follows : atrio-His block, 7(17.1%) ; His-ventricular block, 6(14.6%) ; normal conduction due to prolonged A2H2, 9(22.0%). But there was no statistical significance between the pattern of A-V conduction and the longest S2H2 & H2V2 intervals during VAB (p-value=0.235>0.050). In conclusion, atrial extrastimulation which is routinely done during clinical EPS is an effective method to induce aberrant ventricular conduction and to study the electrophysiologic characteristics of atrioventricular conduction. Further study with recording of bundle branch electrogram, after infusion of cardioactive drugs and pacing of HRA at fixed rate should be done to determine the electrophysiologic properties of VAB more completely.

BACKGROUND: In this study, we investigated the long-term clinical results and survival rate of minimally invasive unicompartmental knee arthroplasty (UKA) by collecting cases that had been implanted more than 10 years ago. METHODS: One hundred and twenty-eight patients (166 cases) who underwent Oxford phase 3 medial UKA using the minimally invasive surgery from January 2002 to December 2002 were selected. The mean age of the patients at the time of surgery was 61 years, and the duration of the follow-up was minimum 10 years. Clinical and radiographic assessments were performed using the Knee Society clinical rating system, and the survival analysis was done by the Kaplan-Meier method with 95% confidence interval (CI). RESULTS: The mean Knee Society knee and function scores improved significantly from 53.8 points (range, 25 to 70 points) and 56.1 points (range, 35 to 80 points) preoperatively to 85.4 points (range, 58 to 100 points) and 80.5 points (range, 50 to 100 points) at 10-year follow-up, respectively (p < 0.001). Failures following the UKA occurred in 16 cases (9.6%), and the mean time of the occurrence of the failure was 6.2 years after the surgery. The 10-year survival rate was 90.5% (95% CI, 85.9 to 95.0) when failure was defined as all the reoperations, whereas the 10-year survival rate was 93.4% (95% CI, 89.6 to 97.1) when the cases in which only revision total knee arthroplasty was defined as failure. CONCLUSIONS: The results of this study show outstanding functions of the knee joint and satisfactory 10-year survival rate after minimally invasive UKA. Therefore, minimally invasive UKA could be a useful method in the treatment of osteoarthritis in one compartment of knee joint.

To evaluate effect of coronary collateral circulation on left ventricular function in patients with acute myocardial infarction, global ejection fraction(EF), left ventricular end distolic pressure(LVEDP), peak creatine kinase(CK) level and regional wall motion were analysed and compared in 30 patients with acute myocardial infarction according to grade of coronary collateral circulation. Patients with total or near total(above 95% of diameter) occlsion of left anterior descending coronary artery without significant lesion in right coronary artery or left circumflex artery were selected and divided into 3 groups according to the degree of collateral circulation on coronary angiography, to be compared by the index of ejection fraction, peak creatine kinase level, left ventricular and diastolic pressure and regional wall motion. The result are as following : 1) There were no statistically significant differences in ejection fraction, peak creatine kinase level, left ventricualr and diastolic pressure among the groups. 2) Regional wall motion of infarct related area of G2+3 group(adequate collateral) were better than that of G0(no collateral) group(p<0.05). Therefore, adequate coronary collateral circulation in acute myocardial infarction is thought to have beneficial effect on left ventricular function especially in regional wall motion of infarct related area.

Hereditary vitamin D resistant rickets (HVDRR) is a rare genetic disorder caused by a mutation of vitamin D receptor (VDR) gene. A number of cases had been reported in many countries but not in Korea. We examined a three-year old Korean girl who had the typical clinical features of HVDRR including rickets, hypocalcemia, hypophosphatemia, elevated serum calcitriol level and secondary hyperparathyroidism. The girl and her father were both heterozygous for the 719 C-to-T (I146T) mutation in exon 4, whereas she and her mother were both heterozygous for 754 C-to-T (R154C) mutation in exon 5 of the VDR gene. In this familial study, we concluded that the girl had compound heterozygous mutations in her VDR gene which caused HVDRR. This is the first report of a unique mutation in the VDR gene in Korea.

Spontaneous pneumothorax is rarely occurred as an initial sign of primary lung cancer. As a lot of these cases have already advanced, even then surgical resection is performed, the prognosis is often undesirable. We happened to find a ruptured cavity on a 65-year-old male patient who had suffered from pulmonary tuberculosis in the past, while performing VATS bullectomy for simple spontaneous pneumothorax. Then, as a result of frozen biopsy, it was diagnosed as squamous cell cancer. Because the tumor was infiltrated from the upper lobe into the lower lobe passing by fissure, we should remove by pneumonectomy and the pathologic stage was found stage I (T2N0M0). When we made an follow-up observation for one year and a half, there was neither relapse nor complication. When there appears spontaneous pneumothorax to the high risk group for lung cancer who were smokers over forty-year old, with chronic bronchitis or pulmonary emphysema, it needs to have a closer observation on a base lung disease such as lung cancer through chest CT, and it is also necessary to make more active approach by performing the surgical operation through a thoracoscopy when there is a continued air release.

Aorto-cutaneous fistula is a rare complication after performing open heart surgery, but if this develops, it is a fatal condition. So, prompt diagnosis and aggressive surgical treatment is needed. We report here on a patient who had two mechanical double valves placed during heart surgery and she was treated for repeated sternal wound infections for about 5 years. She visited the ER due to abrupt bleeding at the sternal wound. She was diagnosed as having an aorto-cutaneous fistula by performing an aortogram and we then performed cardio-pulmonary bypass surgery. The patient is currently doing well and is under follow up 24 months after the repair.
