PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

We have experienced a patient (4-year-old female) with a granular cell tumor (GCT), Examination of patients skin showed a bean sized asymtomatic firm nodule on the left baek. Exciaional biopsy and histopathologic examination were perforrned under the impression of angiolipoma. The specirnen revealed a distinctive picture of GCT.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

BACKGROUND: The dose-responses of neuromuscular blocking agents may be influenced by many factors including age and inhalation anesthetics. This study was designed to determine the dose-response relationships of a new, short-acting muscle relaxant, mivacurium during nitrous oxide-halothane or nitrous oxide-enflurane anesthesia in two age groups, infants and 1 to 6 years old preschool children. METHODS: Neuromuscular blockade was monitored by recording the accelerographic activity of the adductor pollicis muscle resulting from supramaximal stimulation at the ulnar nerve at 2 Hz for 2 seconds at 10-second intervals. To estimate dose-response relationships, 24 infants or children of two anesthetic subgroups for each age group received single bolus doses of 45~100 g/kg of mivacurium. The ED50 and ED95 were estimated from linear regression plots of log-dose vs probit of twitch depression. The lag time, onset time and maximal depression of twitch height for the selective medium dose were mesured. RESULTS: The ED50 and ED95 for the infants group were 38.2 and 53.3 g/kg during halothane anesthesia, and 29.8 and 48.6 g/kg during enflurane anesthesia, respectively. And, those for preschool children group were 49.4 and 90.7 g/kg during halothane anesthesia, and 32.3 and 81.4 g/kg during enflurane anesthesia, respectively. There was a parallelism of the dose-response curve between halothane and enflurane anesthesia in either age group. Also, there was statistically significant difference in the maximal twitch depression for the selective medium dose of mivacurium between halothane and enflurane anesthesia in either group. CONCLUSIONS: The potency of mivacurium during enflurane anesthesia is higher than that during halothane anesthesia in infants and preschool children, and during either inhalation anesthesia the dose of mivacurium is less required in infants than preschool children.

The classical Roentgenographic features of tuberculosis of the spine such as narrowing of the intervertebraldisc, collapse of the vertebral bodies, with or without the shadow of a cold abscess, present a specific pictureof the actural pathological process. However, the diagnosis of tuberculosis is not confirmed unless proven bybiopsy, or the finding of the tubercle bacillus. 120 cases of proven spinal tuberculosis, at Kwangju ChristianHospital during the period form Jan 1973 through Aug. 1980, were studied and analysed. The results were asfollows; 1. The ratio of male to female was 1:1.1. The age preference was under 30 years old. 2. The most frequentsite of involvement was the lumbar spine(44.1%) and next the thoracic(39.2%0. 3. The incidence of lytic type was50.8%, mixed type 36.7%, and sclerotic type 12.5%. 4. Associated pulmonary tuberculous lesions were observed in 94patients (78.3%). 5. The central type, with wedging or collapse of the vertebral body, was more common in theyounger age group and the intrevertebral articular type in older patients. 6. The incidences of typical radiologicfindings were : Collapse of vertebral body(90%), cold abscess (78.3%) and narrowing of intervertebral space(70%).7. Associated kyphosis was observed in 37 cases (30.8%). Among these 37 cases the range of angulation was between21 to 40 degrees in 40%.
