Osteochondritis dissecans of the capitellum is a condition which causes pain and limitation of motion in the elbow joint. Conservative management can be done in the early stage, but operative method is indicated when conservative treatment failed or loose bodies causing symptoms developed. The authors experienced 20 cases of osteochondritis dissecans of the capitellum, which received satisfatory surgical treatment, such as 1) removal of loose body, 2) removal of loose body, curettage, and multiple drilling, 3) curettage and multiple drilling at the Department of Orthopedic Surgery, National Police Hospital, from January, 1985 to August 1989. Following results were obtained. 1. The occupations were baseball players in 5 cases (25%), gymnast in 4 csses (20%), tennis player in 1 case (5 %), which implicates repetitive trauma or excessive use of the elbow joint as a cause of osteochondritis dissecans of the capitellum. 2. The main symptoms were pain in all cases(100%), limitation of range of moiton(70%), locking(25%), swelling of the joint, and clicks on range of motion in decreasing order. 3. Of the 20 cases, removal of loose bodies was performed in 13 cases(65%), removal of loose bodies, curettage, and multiple drilling in 4 cases (20%), and curettage and multiple drilling in the remaining 3 cases (15%), And follow-up results were excellent in 16 cases (80%), good in 3 cases (15%), and moderate in 1 case (5%). So, we concluded that the above surgical measurements are good enough to give satisfactory results for osteochondritis dissecans of the capitellum.

OBJECTIVE: The purpose of this study was to evaluate hemodynamics for diabetes mellitus (DM) by transcranial Doppler sonography (TCD) and to evaluate the influences of risk factors to cerebral hemodynamics in DM. METHOD: We examined 54 normal persons, 17 patients with DM without risk factors, and 15 patients with DM and risk factors. The risk factors were hypertension, smoking, and hyper lipidemia (total cholesterol >240 mg/dl, low density lipoprotein >160 mg/dl). Mean blood flow velocity (MBFV) was also analyzed by Angiodine 2 Doppler system operating at 2 MHz frequency from each subjects. RESULTS: There was a significant decrease of MBFV in the diabetes in comparison to control groups (p<0.05). There was a significant decrease of MBFV in the diabetic risk group as compared to diabetic non-risk group (p<0.05). There was significantly increased total cholesterol, low density lipoprotein, low density lipoprotein/high density lipoprotein ratio in the diabetic risk group as compared to diabetic non-risk group (p<0.05). MBFV significantly decreased with increasing concentration of HbA1C and duration of DM (p<0.05). CONCLUSION: We suggest that transcranial Doppler sonography can be used as one of the useful screening tests for early detection of cerebrovascular diseases in DM.

OBJECTIVE: To determine whether flexion and extension of the wrist joint produce the change in the conduction study of the median nerve in the normal and diabetic patients, and to compare the susceptibility of median nerve compression injury in two groups. METHOD: Thirty healthy adults as control and thirty diabetic patients without carpal tunnel syndrome were studied. The wrist joint was maintained in flexion or extension position for 5 minutes before performing conduction study. The variables used for statistical analysis included the mean difference of amplitude and latency in median motor and sensory responses in neutral, flexion, and extension positions. RESULTS: The results showed that significant differences in the latency and amplitude of median motor and sensory responses between neutral, extension, and flexion of wrist within each group (p<0.01). The differences in the median sensory latency (p<0.01), amplitude (p<0.05) and the change of wrist-palm segmental conduction velocity (p<0.01) were statistically significant between the diabetes and the normal control. CONCLUSION: The results of this study suggest that median nerves are susceptible to compression pressure in diabetic patients. Therefore, the position of the wrist joint should be considered in the median nerve conduction study.

OBJECTIVE: To investigate the regional differences of skin blood flow and to evaluate the effects of foot temperature on the severity of neuropathic pain and to predict the development of plantar foot ulceration by measuring of the temperature variations on the plantar surface of feet in the diabetic patients. METHOD: We measured the temperature variations on plantar surface of the feet in controls (n=18) and diabetic patients with(n=20) or without(n=23) polyneuropathy. The surface temperature from the 3rd metatarsal head(MTH), greater toe(GT), heel, medial and lateral longitudinal arch(LA) was measured by Digital Infrared Thermographic Imaging(DITI). RESULTS: The mean foot temperature of diabetic patients with polyneuropathy was significantly increased compared to controls or diabetic patients without polyneuropathy(p<0.001). The surface temperature readings of the GT, medial LA and the 3rd MTH tended to be increased in controls and patients with polyneuropathy. The mean plantar surface temperature was significantly increased according to the duration of diabetes mellitus(DM)(p<0.05). CONCLUSION: The results suggest that DITI provides a diagnostic modality in the prediction of neuropathic foot and increased risks of foot ulcer development in the diabetic patients.

BACKGROUND: Bronchial asthma is characterized by a reversible airway obstruction, airway hyperresponsiveness, and eosinophilic airway inflammation. The bronchodilator response(BDR) after short acting beta agonist inhalation and PC20 with methacholine inhalation are frequently used for diagnosing bronchial asthma, However, the relationship between the presence of a bronchodilator response and the degree of airway hyperresponsiveness is uncertain. Therefore, the availability of a eosinophil cationic protein(ECP) and a correlation ECP with a bronchodilator response and airway hyperresposiveness was investigated. METHOD: A total 71 patients with a moderate to severe degree of bronchial asthma were enrolled and divided into two groups. 31 patients with a positive bronchodilator response and 38 patients with a negative bronchodilator response were evaluated. In both groups, the serum ECP, peripheral blood eosinophil counts, and total IgE level were measured and the methacholine bronchial provocation test was examined. RESULTS: There were no differences observed in age, sex, atopy, and baseline spirometry in both groups. The peripheral eosinophil counts showed no difference in both groups, but the ECP level in group 1 (bronchodilator responder group) was higher than in group 2(non-bronchodilator responder group) (22.4±20.7 vs 14.2±10.4, mean±SD). The PC20 in group 1 was significantly lower than in group 2 (1.14±1.68 vs 66±2.98). There was a significant positive correlation between the BDR and ECP, and a negative correlation between the bronchial hyperresponsiveness and ECP. CONCLUSION: The bronchodilator response significantly correlated with the bronchial hyperresponsiveness and serum ECP in the moderate to severe asthma patients. Hence, the positive bronchodilator response is probably related with active bronchial inflammation and may be used as a valuable index in treatment, course and prognosis of bronchial asthma.

BACKGROUND: Atrial fibrillation (Af) after open heart surgery may result in hypotension, heart failure, embolic complication and prolongation in length of hospital stay. Several studies have investigated the efficacy of pharmacological prophylaxis in reducing the incidence of Af after cardiac surgery. The pericardial sac represents a natural physical barrier and provides a drug receptacle to restrict drug delivery to the heart. The overall objective of this study was to determine whether the pericardial sac could function as a delivery chamber for antiarrhythmic drugs. We investigated whether quinidine delivered into the pericardial sac exerted an effect on atrial and ventricular refractoriness, impulse generation, and conduction. METHODS: All animals were anesthetized with alpha-chloralose. After a sternotomy, the pericardium was opened and cradled to produce a "container" of approximately 30 ml. Experimental animals received quinidine, 3.33 mg/ml, dissolved in Krebs-Henseleit solution instilled into their pericardial sacs for 30 minutes. Baseline and 5, 10 and 30 minutes postinstillation electrophysiologic studies were performed. Plasma quinidine levels were measured at each of the time intervals in three different sites i.e., right ventricle (RV), aortic root and femoral vein (FV). RESULTS: Baseline systolic (SAP) and diastolic aortic pressure (DAP) were 148+/-16.8 mmHg, and 111+/-23.9 mmHg, respectively. Both SAP and DAP were significantly decreased at 5, 10 and 30 minutes after instillation of quinidine solution into pericardial sac. In electrocardiographic parameters, the increase in sinus cycle length and corrected QT interval were significantly greater compared with baseline at each of the time intervals after instillation of quinidine solution into pericardial sac. All electrophysiologic parameters including 1:? AV conduction, effective refractory period (ERP) of RA and RV were significantly increased compared with baseline at three time points. Quinidine concentrations in RV and aorta were significantly higher than in FV at three time points. In RV and aorta, quinidine concentrations at 30 min were significantly lower than those at 5 and 10 min postinstillation periods. There were significant correlations between plasma quinidine levels and corrected QT interval or RAERP. CONCLUSION: Above results showed that quinidine instilled into the pericardial sac migrates transmurally and produces significant prolongation of effective refractory period and may appear to prevent various arrhythmias including atrial fibrillation after cardiac surgery.

BACKGROUND: Low dose dobutamine echocardiography has recently been introduced for use in identification of viable myocardium in patients with acute myocardial infarction and prediction of the response of dysfunctioning myocardial segments to coronary angioplasty. The aim of this study was to evaluate wheter tihs test could be used to predict the early response of dysfunctioning myocardial segements to coronary artery bypass grafting(CABG). METHODS: We studied in 23 patients with multi-vessel disease during CABG. Myocardial segments were monitored by intraoperative transesophageal echocardiography(TEE) in the transgastric short-axis view at papillary muscle level. The left ventricle was divided into five segments and sixty eight myocardial segments in 23 patients were analyzed. Percentage of systolic wall thickening(PSWT) was calculated in each segment for three times: at basline(early after pericardiectomy);before bypass during dobutamine infusion(3-5ug/kg/min);and after seperation from cardiopulmonary bypass. Segments showing baseline PSWT >_30% were considered normal and those < 30% were dysfunctional. Segments showing an increase in PSWT >_10% during dobutamine infusion were considered responders and those < 10% nonresponders. RESULTS: AT baseline, 24%(36%) of 68 segments had PSWT > 30%(normal) and 44(68%) had PSWT < 30%(dysfuctioning segments). During dobutamine infusion, 21(47.7%) among 44 dysfunctional segments showed increase in PSWT >_10%(from 12.3+/-7.2% to 33.5+/-11.8%, p<0.01 ; responder segments), and 23(52.3%) showed increase in PSWT < 10%(from 14.7+/-6.5% to 17.4+/-7.4%, p=NS ; nonresponder segments). After CABG, responder segments showed a significant increase in PSWT in comparison with baseline values(from 12.3+/-7.2% to 32.1 +/-11.0%,p<0.01). Segments not responded to dobutamine showed no significant changes in PSWT after CABG(from 14.7+/-6.5% to 16.0+/-8.2%, p=NS). Twenty-four normal segments (PSWT 41.9+/-6.2%) showed a slight but significant reduction in PSWT both during dobutamine infusion(38.7+/-6.9%;p<0.05) and after CABG(38.9+/-6.3%, p<0.05), suggesting that compensatory hyperfunction was present at baseline. Estimation of clinical accruacy of low dose dobutamine TEE yieded to 69% sensitivity, 93.9% specificity, 95.2% positive predictive value, 60.9% negavive predictive value, and 77.3% overall accuracy. In both responders and nonresponders of dysfunctioning segments, there was a correlation between PSWT during dobutamine infusion and that after CABG(r=0.61, r=0.63, respectively). CONCLUSION: Low dose dobutamine TEE test well predicts the early response of dysfunctioning myocardial segments to CABG.

BACKGROUND/AIMS: Hepatic nerve innervation plays important roles in hepatic metabolism and hemodynamic mechanisms. We compared the distribution patterns of hepatic nerves between normal livers and two liver diseases to elucidate the effects of liver disease on the distribution of hepatic nerves. METHODS: Tissue specimens were obtained by ultrasonography-guided needle biopsies from 10 normal controls, 74 patients with chronic hepatitis (CH), and 35 patients with liver cirrhosis (LC). The obtained specimens were immunohistochemically stained using antibodies for S-100 protein and alpha-smooth-muscle actin (alpha-SMA). The degree of the expression in liver tissues was quantified by manual counting of positively stained nerve fibers under light microscopy. The serum hyaluronic acid level was assayed in all subjects to evaluate hepatic fibrosis. Electron microscopy examinations were also performed. RESULTS: The hepatic nerve innervation was significantly lower in LC than in normal controls, as indicated by S-100 protein staining. alpha-SMA and hyaluronic acid levels were higher in LC and CH than in normal controls. Electron microscopy revealed that unmyelinated nerve fiber bundles in the intralobar connective tissue coursed in the vicinity of hepatic triads. CONCLUSIONS: These results suggest that hepatic nerve innervation can be decreased by hepatic inflammatory responses and/or fibrotic changes in LC patients. Further study is needed to clarify this observation.

OBJECTIVE: Adiponectin is an adipocyte-derived hormone with profound insulin sensitizing, anti-inflammatory, and antiatherogenic effects. Apart from its obvious potential as a mediator of adult metabolic syndrome, in pregnancy, adiponectin could have a significant role in regulating energy homeostasis. However, correlations between umbilical cord and maternal serum adiponectin levels and neonatal birthweights are far from understood. The purpose of the present study was to clarify correlations between umbilical cord and maternal serum adiponectin levels and neonatal birthweights. METHODS: The study included 30 healthy mothers who had given birth to healthy neonates. Adiponectin levels in maternal serum and umbilical cord serum were determined by ELISA and analysed. RESULTS: The ranges of adiponectin levels for umbilical cord and maternal serum were 7.12-24.93 microgram/mL and 1.76-8.20 microgram/mL, respectively. Umbilical cord adiponectin levels (14.82+/-3.66 microgram/mL) were significantly higher than maternal serum levels (4.73+/-1.87)(p<0.001). Umbilical cord adiponectin levels were correlated positively with neonatal birthweights (r=0.459, p=0.011). No significant differences in adiponectin levels were found between female and male neonates. In addition, there was no correlation between umbilical cord adiponectin levels and maternal serum adiponectin levels, maternal body mass index, umbilical leptin, or insulin levels. CONCLUSION: The levels of adiponectin were higher in umbilical cord than in maternal serum. The adiponectin levels in umbilical cord were found to correlate positively with neonatal birthweights. Therefore, adiponectin may be involved in fetal energy metabolism in pregnancy.
