Subungual exostosis are not uncommon, however, they are infrequently mentioned in the dermatologic literature. We report herein a rase of subungual exostosis in the great toe of 16-year-old female student which was confirmed by histopathologic and radiologic findings. Histopathologic examination showed that the mass was ooeered by a dense fibrous tissue which merged into a fibrocartilage cap and bone. Computed tomography showed a well defined, oval shaped, radiopacity of bony density capped by a radiolucency.

PURPOSE: We wanted to evaluate whether both the colonic transit time (CTT) and defecography are necessary for diagnosing constipated patients, and we also wanted to assess the defecographic findings of patients with outlet obstruction on CTT. MATERIALS AND METHODS: Over the recent 3 years, 26 patients (21 women and 5 men, mean age: 59 years) underwent both CTT and defecography because of their chronic constipation or defecation difficulty. The mean interval between the 2 studies was 48 days. Colonoscopy, barium enema and manometry were performed in 22, 8 and all the patients, respectively. RESULTS: On CTT, 13 patients (50.0%) were normal and 13 patients (50.0%) were abnormal; the abnormal results were composed of outlet obstruction (n=8, 30.8%), outlet obstruction and colon inertia (n=2, 7.7%), colon inertia (n=2, 7.7%), and outlet obstruction and hindgut dysfunction (n=1, 3.8%). On defecography, 6 patients (23.1%) were normal and 20 patients (76.9%) were abnormal; the results were composed of rectocele (n=8, 30.7%), rectocele and perineal descent syndrome (PDS; n=4, 15.4%), PDS and rectal intussusception (n=3, 11.5%), spastic pelvic floor syndrome (SPFS; n=3, 11.5%), rectocele and SPFS (n=1, 3.8%), and rectal intussusception (n=1, 3.8%). Of the 11 patients with outlet obstruction on CTT, rectocele (n=4, 36.4%), SPFS (n=1, 9.1%), rectocele and PDS (n=1, 9.1%), and PDS and rectal intussusception (n=1, 9.1%) were demonstrated on defecography, except for the 4 normal cases. CONCLUSION: Both CTT and defecography were necessary for diagnosing the patients with chronic constipation in compensation, and 63.6% of the patients with pelvic outlet obstruction showed an abnormal pelvic defecation function.

Nodular hepatic involvement of multiple myeloma is very rare. We report here on a case of nodular hepatic involvement of multiple myeloma that mimicked intrahepatic cholangiocarcinoma. In patients with multiple myeloma, hepatic involvement of the multiple myeloma might be included in the differential diagnosis of hepatic mass.

BACKGROUND: Stereotactic thalamotomy and pallidotomy for Parkinson's disease or essential tremor have been performed under local anesthesia. But some neurosurgeons have been reluctant to utilize this technique because of patient discomfort and neurological complications. So we used the propofol that provides excellent sedation and rapid and smooth recovery of mental abilities with minimal side effects. METHODS: After the patients were placed into the Leksell's stereotactic frame, anesthesia was induced by continuous infusion of propofol at the rate of 150 mcg/kg/min and then maintained at the rate of 50 mcg/kg/min. We investigated the hemodynamic changes, ABGA, total dose of propofol, time to loss of consciousness, recovery time from the end of infusion to eyes opening and side effects. RESULTS: The blood pressure decreased significantly at infusion start 15 min and 30 min (p<0.05) and heart rate decreased significantly at infusion start 30 min (p<0.05). The PaCO2 increased significantly at infusion start 15 min and 30 min (p<0.05). Total dose of propofol was 202.4+/-59.8 mg, time to loss of consciousness was 13.0+/-4.4 min, recovery time was 9.0+/-4.7 min and side effects were pain on infusion (2 cases) and postoperative nausea (1 case). CONCLUSIONS: Stereotactic thalamotomy and pallidotomy for Parkinson's disease or essential tremor were performed by infusion of propofol with minimal side effects and no neurological complications.

PURPOSE: To determine by quantitative evaluation of pancreatic and adjacent vascular enhancement during spiral CT, the ideal scan delay for examination of the pancreas. MATERIALS AND METHODS: Dual (n=90) and triple (n=90) phase spiral CT scans of patients whose pancreas showed no pathologic condition were retrospectively evaluated. Dual-phase scans were performed at 43 seconds (early), and 5-6 minutes (delayed) after the injection of 120ml of contrast material at an injection rate of 3ml/sec ; triple-phase scans were performed at 25 seconds (arterial), 60-65 seconds (portal) and 5-6 minutes (delayed) after the injection of 120-140ml of contrast material at an injection rate of 2-4ml/sec, and ten patients also underwent precontrast scanning. CT attenuation values (HU) were measured in the head, body and tail of the pancreas, aorta, and main portal vein during each phase of all scans. Triple-phase protocol was used to measure the effect of different total volumes and injection rates on enhancement of the pancreas and adjacent vessels. RESULTS: There was no significant difference in the degree of enhancement of the pancreas head, body and tail during each phase (p>0.05). The pancreas was maximally enhanced on 43 second delayed scan (132+/-20 HU)(p<0.05), and the aorta, on 25-second delayed scan (269+/-74 HU), but there was no significant difference between this enhancement and that seen at 43 seconds(p>0.05). The main portal vein showed maximum enhancement on 43-second delayed scan (207+/-44 HU)(p<0.05). Different total volume of contrast material did not change the enhancement of the pancreas and adjacent vessels. At an injection rate of 2ml/sec, peak enhancement of the pancreas, aorta and portal vein was obtained on 60-65 second delayed scan, and at 4ml/sec, peak enhancement was obtained on 25 second delayed scan(p<0.05). CONCLUSION: Observing the usual protocols for abdominal spiral CT scanning, the pancreas was most effectively evaluated using a 43-second delayed scan. An increased injection rate resulted in earlier enhancement of the pancreas, aorta and portal vein.

Primary idiopathic polymyositis is a condition of presumed autoimmune etiology in which the skeletal muscle is damaged by a nonsuppurative inflammatory process dominated by lymphocytic infiltration. We recently experienced a patient with primary idiopathic Polymyositis associated with hypoalbuminemia and thrombocytopenia. About 4 months prior to admission, he was diagnosed as primary idiopathic polymyositis, and improved by treatment with prednisolone 60 mg/day. During steroid tapering, muscle weakness was recurred and accompanied by hypoalbuminemia and thrombocytopenia. Despite retreatment with prednisolone 60 mg/day, muscle weakness, hypoalbuminemia and thrombocytopenia persisted. He was then started to administer methotrexate(MTX) 15 mg/week which resulted in prompt improvement of muscle weakness, hypoalbuminemia and thrombocytopenia. These findnigs suggest that primary idiopathic polymyositis is one of the cause of hypoalbuminemia and thrombocytopenia, and that the hypoalbuminemia and thrombocytopenia can be improved promptly by methotrexate treatment.

BACKGROUND: Malignant hyperthermia (MH) is a hypermetabolic disorder of skeletal muscle that manifests after exposure to triggering episodes such as halothane or succinylcholine. The first case was reported in Australia on 1960 by Denborough. In Korea the first case report was made by Lim on 1971. The authors retrospectively analysed the reported cases of MH and/or masseter muscle rigidity in Korea for the establishment of appropriate diagnostic criteria and rapid treatment. METHODS: Twenty-one cases of MH and 2 cases of masseter muscle rigidity were analysed retrospectively form 1971 to 1995. These cases were reported in Journal of Korea Society of Anesthesiology and Journal of Research Institute of Medical Science of Korea. The analyzed items were age, department, anesthesia, symptoms and signs, drugs for treatment, history of patient and family and prognosis of MH. RESULTS: The incidence of MH was higher in male patients below the 4th decade of life. The rate was 0.6 per year from 1971 to 1995. In nineteen patients, inhalation anesthetics with succinylcholine were suspected as triggering agents and 4 patients' conditions were related to spinal anesthesia by tetracaine. Only one case of MH occured within 10 min. after induction, but 22 cases occured during operations or the recovery period, and one case in the ward. The most common initial signs were muscle rigidity, high fever with arrhythmia and increased blood pressure. Related laboratory findings were acidosis, elevated end tidal CO2, and hyperkalemia. Six cases had family histories or past histories related to MH. CONCLUSIONS: The incidence of MH is progressively increasing in Korea. But MH will be prevented and treated effctively. So we should prepare a monitoring system for early detection and a supply of dantrolene for treatment. These precautions will spread nationwide and will need the support of the anesthesiology society and the goverment.

BACKGROUND: High dose fentanyl anesthesia has been recommended for circulatory stability during coronary artery bypass grafting (CABG), but hypertension and tachycardia in response to noxious stimulation have been noted. The purpose of this study was to evaluate the hemodynamic effects of extensive thoracic epidural analgesia (TEA) combined with general anesthesia (GA). METHODS: The hemodynamic effects in CABG were evaluated in 30 patients. They were randomized into two groups ; the GA group receiving high dose fentanyl (50-70 mcg/kg), the TEA group receiving 10 ml bupivacaine 5 mg ml 1 followed by 5 ml every two hours epidurally GA (N2O-O2). The hemodynamic parameters were evaluated before induction of anesthesia, 20 minutes after induction of anesthesia, after sternotomy, and 30 minutes after end of cardiopulmonary bypass. RESULTS: Heart rate and mean arterial pressure were significantly lower after sternotomy in the TEA group compared to the GA group. Significant increase in cardiac index and decrease in central venous pressure, mean pulmonary arterial pressure, pulmonary capillary wedge pressure were found after induction of anesthesia and sternotomy in the TEA group compared to the GA group. Especially, the pulmonary vascular resistance was significantly lower during all the period in the TEA group compared to the GA group. No differences were observed in stroke volume index, systemic vascular resistance, left ventricular stroke work index between two groups. CONCLUSIONS: The present study suggests a more effective blockade of the stress response during CABG with TEA than with GA. So, we consider that TEA could be used as an adjunctive anesthetic method during CABG.

BACKGROUND: The correlation between the high resolution computed tomography(HRCT) emphysema score and the physiologic parameters including resting and exercise pulmonary function test was investingated in 14 patients(60.6±10.3 years) with pulmonary emphysema. METHODS: The patients underwent a HRCT, a resting pulmonary function test, and incremental exercise testing(cycle ergometer, 10 W/min). Computed tomography scans were obtained on a GE highlight at 10 mm intervals using 10 mm collimation, from the apex to the base after a full inspiration. The emphysema scores wer determined by a CT program 'Density mask' outlining the areas with attenuation values less than -900 HU, indicating the emphysema areas, and providing an overall percentage of lung involvement by emphysema. RESULTS: Among the resing PFT parameters, only the diffusing capacity(r=-0.75) and PaO2 (r=-0.66) correlated with the emphysema score(p<0.05). Among the exercise test parameers, the emphysema score correlated significantly with the maximum power(r=-0.74), maximum oxygen consumption(r=-0.68), anaerobic threshold(V-slope method : r=-0.69), maximal O2-pulse(r=-0.73), and the physiologic dead space ratio at the maximum workload(r=-0.80)(p<0.01). CONCLUSION: We could find that exercise testing parameters showed a much better correlation with the HRCT emphysema score, which is known to have a good correlation with the pathologic severity than the resting PFT parameters. Therefore it is suggested that exercise testing is superior to resting PFT for estimating in the estimation of the physiologic disturbance in emphysema patients.
