Cerebral white matter changes (WMCs) and silent brain infarcts (SBIs) are common radiologic findings in neurologically asymptomatic elderly people, but are associated with an increased risk of subsequent stroke. We investigated the prevalence and risk factors for these cerebral changes on brain computed tomography (CT) in 480 community-dwelling healthy Korean adults without stroke or dementia, who were recruited for an early health program. Cerebral WMCs were defined as the presence of approximately 5 mm wide ill-defined and moderately hypodense lesions, and SBIs were defined as the presence of >2 mm wide well-defined hypodense lesions. Of the 480 patients, 49 (10.2%) had cerebral WMCs and SBIs findings on brain CT. The prevalence of WMCs and SBIs increased with age: the prevalence was 2.4%, 9%, and 32% for subjects in their 50, 60s, and 70s, respectively. In addition, hypertension, abdominal obesity, increased levels of homocysteine and high sensitivity C-reactive protein were significantly associated with cerebral WMCs and SBIs. Our study suggests that regular monitoring of risk factors is required to prevent cerebral WMCs and SBIs and decrease the incidence of stroke and dementia in healthy individuals.

Sparganosis is an infection that is caused by sparganum, the migrating plerocercoid larva of Spirometra spp. Manson first reported this condition in 1882. In Korea, Uemura reported the first case in 1917 in the muscle facia of a Korean farmer during the amputation of his leg. Since then, more than 100 cases have been reported. However, the number of unreported cases of sparganosis would be considerable. Human sparganosis is widely distributed in Japan, China, Taiwan, Korea, Philippine, Malaysia, India, Australia, Africa, France, England and USA. Most human cases are from Southeast Asia including Japan and Korea. Sparganosis commonly involves the subcutaneous tissue, muscles, fascia with occasional migration into the brain. We report 3 cases of sparganosis, a 42 year old man, a 55 year old man and a 41 year old woman, who all presented with a tender mass in the right thigh.

BACKGROUND: The purpose of this study was to compare prospectively two different anesthetic techniques with isoflurane or propofol for postoperative nausea, vomiting and recovery after tonsillectomy in children. METHODS: Sixty children, ASA physical status I, were assigned randomly to one of two groups. In group I, anesthesia was induced with thiopental 5 mg/kg and maintained with isoflurane 1~1.5 vol%. In group P, anesthesia was induced with fentanyl 1 mcg/kg, propofol 2 mg/kg and maintained with propofol infusion 5~10 mg/kg/hr. Both group received vecuronium 0.1 mg/kg for tracheal intubation and were ventilated with 33% O2 in N2O. The time to extubation, time to eye opening, PACU time, incidence and numbers of postoperative nausea and vomiting, and degree of sedation were recorded as well as perioperative complications. RESULTS: There were no significant difference in the duration of anesthesia and PACU time between two groups. The time to extubation and eye opening of group P were significantly shorter than group I (p<0.05). The degree of sedation and incidence of postoperative nausea and vomiting of group P were significantly lower than group I (p<0.05). But the frequency of intraoperative bradycardia was significantly higher in group P than group I (p<0.05). CONCLUSIONS: Propofol-fentanyl anesthesia results in less nausea and vomiting during postoperative period and more rapid recovery compared to isoflurane anesthesia and may be recommended in children undergoing tonsillectomy and adenoidectomy.

Disseminated intravascular coagulation (DIC) is a pathological syndrome in which activation of coagulation cascade leads to fibrin clot formation, consumption of platelets and coagulation factors, and secondary fibrinolysis. We report a case of severe postoperative hemorrhagic diathesis due to DIC. A 59-year-old man was scheduled for reduction of tibia fracture and anatrophic nephrolithotomy of staghorn calculi. On the fifth postoperative day, second operation was performed for nephrectomy due to perirenal hematoma. Two days later, third operation was performed for hemostasis because of the continuous bleeding. Coagulation tests showed positive DIC profiles of thrombocytopenia, hypofibrinogenemia, increased fibrin degradation products, and prolonged prothrombin time and thrombin time. The patient recovered uneventfully and discharged on the 59th postoperative day.

Clear cell sarcoma of tendon and aponeurosis is a rare malignant tumor. It occurs chiefly in young adults, predominates in women and is most common in the regions of the foot and ankle. We report a case of clear cell sarcoma of tendon and aponeurosis in s 22-year-old man. he pstient had had a asymptomatic, normal skin colored, relativerly hard, dome shsped nodule on the anterior chest for 6 months. Histopsthologic findings revealed uniform pattern composed of compact nests of round or fusiform cells which had clear cytoplasm and were surrounded by delicate framework of fibrocollagenous tissue, and the individual tumor cell had a fairly regular appearance of possessing round to avoid vesicular nucleus with prominent basophilic nucleolus. One year after surgical excision and post operative radiotherapy, there was no recurrence.

During January 1975 to December 1979, myelographic studies followed by operation was carried out on 150 cases of lumbar H.I.V.D. at Chung Nam National University Hospital. As to the myelographic findings, mode, level of indentation, and positive and negative finding were analyzed in comparison with operative findings. The followings results were obtained: 1. Plain radiography has a Iittle value In diagnosis of Iumbar H.I.V.D. about one third of 150 cases show significant sign in plain film study. 2. The major discrepancies between myelographic and operative findings were found in 11.3%, while the minor discrepancies were 4%, so giving an accuracy of 84.7%. 3. Positive myelographic finding(120 cases) consisted of smooth round defect in 83 cases (48.8%), unilateral wedge defect In 45 cases (26.4%), block defect In 18 cases (10.5%), bilateral wedge defect in 13 cases (7.6%), and hourglassdefect In 11 cases (6.4%), respectively. 4. Operative findings revealed the protruded disc: 74.5%, bulging: 11.1%, extruded: 22%, and mlgrated: 1.7%. 5. The myelographic finding of bulging type disc usually showed smooth round filling defect and those of protruded were smooth round filling defect, wedge shape and block filling defect, while the extruded type revealed smooth round filling defect In the most cases. 6. The myelography can be a valuable aid in the determination of the level and degree of H.I.V.D. and very helpful ln differential diagnosis.
