Many modalities of the treatment of fractures of distal 1/3 of tibia were introduced. But, May anatomical bone plate is considered to be a valuable method in treating distal 1/3 tibial fractures because of reduction potentiality by their contour, ability of firm fixation, decreased complications. Twenty two patients having distal 1/3 tibial fractures, were treated by May anatomical bone plate, at the Department of Orthopedic Surgery, Inchon Chirstian Hospital from January 1988 to December 1993. The results were follows; 1. Ninteen cases(86%) out of 22 were closed fractures and the remaining 3 cases(14%) were open fracrues, the comminuted fractures were 6 cases(22%) and the segmental fractures were 2 cases(9%). 2. Average interval from injuy to operation was 16.8 days and 21 cases had associated injuries. 3. The mean duration of bone union was 16.9 weeks. 4. Seven cases(31.8%) of delayed union and two cases(9.1%) of superficial infection were noted.

It is difficult to distinguish benign from malignant, pulmonary nodule by conventional roentgenologic examination. But CT makes it easier to evaluate adjacent parencymal invasion, pleural or mediastinal extenstion,or early metastasis to intra- or extrathoracic lymph node as well as distant organs, although only a solitaryperipheral pulmonary nodule is seen on plain radiograph. Authors reviewed CT of 22 cases of histopathologically confirmed primary lung cancer seen as a solitary peripheral pulmonary mass from May 1980 to Sep. 1984 at DongsanMedical Center, Keimyung University. The results are as follows: 1.The incidence was most common in the 6thdecade(36%). Male to female ratio was 10:1 and 2 females all had bronchioloalveolar cell carcinoma. 2. Thedistributions of histologic cell type were as follows: squamous cell carcinoma 40%, adenocarcinoma, small cellcarcinoma, bronchioloalveolar cell carcinoma and unclassified carcinoma 14% in each cases, and adenoid cysticcarcinoma 4% . 3. The CT findings were as follows: a) Superior and posterior basal segments of both lower lobeswere most frequently involved(68%). b) The mean diameter of the mass was 48mm, and most common in the range of30-49 mm in the greatest dimension(46%). c) The mean CT atttenuation value was 57 H.U., and most common in thegroup of 41-70 H.U. (64%). d) Lymph node metastasis was found in 13 (59%) of 22 cases, and the involved nodes wereas follows: hilar nodes 10 cases, paratracheal nodes 8 cases, subcarinal nodes 7 cases and extrathoracic nodes 3cases. In 2 of 3 cases with small cell carcinoma, diffuse multiple lymph nodes were involved. e) Distantmetastasis was seen relatively early in 3 cases; cerebral metastasis in 1 case of squamous cell carcinoma, rightaderenal metastasis without intrathoracic lymph node metastasis or invasion of adjacent structures in 1 case ofbronchioloalveolar cell carcinoma, and liver and bone metastases in 1 case of unclassified carcinoma. f) Adjacentpleural or mediastinal invasion was found in 7 cases(32%): pleural invasion along chest wall in 4 cases, andinvasion of adjacent mediastinal pleura in 3 cases of 2 squamous cell carcinoma and 1 unclassifed carcinoma. g)Calcifications witihin the mass were found in 5 cases (23%), and most common in squamous cell carcinoma(3 cases).In all cases, a few granular calcification were seen along the peripheral margin of the mass. h) Tumor necrosiswas seen in 4 cases(18%), and 3 cases were squamous cell carcinoma, and one of them showed irregular centralcavitation. i) The margins of tumor were irregularly lobulated with radiating spiculations in all except one ofadenoid cystic carcinoma, which revealed oval shaped, smooth clear margin. j) In 9(41%) of 22 cases, someenlargement of pulmonary vessels with perivascular linear infiltrations were found in the adjacent lungparenchymes of the mass, which were thought to be retrograde perivascular lymphangitic spread along pulmonaryvessels.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.

Authors analysed a series of 175 patients with aneurysmal subarachnoid hemorrhage(SAH) who have undergone the treatment for subarachnoid hemorrhage from July, 1990 to May, 1994 to assess the clinical factors related to clinical vasospasm. This investigation revealed following conclusions. 1) The severity of subarachnoid hemorrhage as seen on computed tomography seemed to be correlated with the appearance of clinical vasospasm. Patients with severe SAH on initial CT scan were at higher risk or clinical vasospasm. 2) Patients with history of hypertension had more significant clinical vasospasm than did normotensive patients after aneurysmal SAH. 3) Aneurysms of the anterior communicating artery were showen to have the highest incidence of clinical vasospasm. 4) Patients with moderate to severe diffuse vasospasm on cerebral angiography had more significant clinical vasospasm than patients with no or local vasospasm. These conclusions suggest that clinical vasospasm after aneurysmal SAH are related to the followi ng predictable factors;amount of blood on the initial CT scan;angiographic vasspasm;history of hypertension and location of aneurysm. Proper management of these factors may diminish the incidence and severity of clinical vasospasm and reduce the morbidity and mortality rate.

Isolated pulmonary stenosis, a relatively common congenital anomaly that accounts for about 10 percent of all congenital heart disease, is characterized by stenosis of pulmonary valve itself, infundibulum or both of them. Since cardiac catherterization was applied to man by Cournand and Ranges, pulmonary stenosis had been easily diagnosed and many clinical studies had been investigated. It has a wide clinical spectrum depending on the degree of stenosis. The electrocardiogram, phonocardiogram and chest X-ray have proved useful in estimating the severity of hemodynamic facotrs in individual cases. This series comprises 47 cases in whom the clinical diagnosis of isolated pulmonary stenosis was confirmed by right heart catheterization with cardiac cineangiography at Severance Hospital, Yonsei University. An attempt was made to correlate the electrocardiographic, phonocardiographic, chest X-ray findings, and types of stenosis with the hemodynamic data in these cases. 1. Of 47 patients, 33 were male and 14 female. Their ages ranged from 2 to 42 years: the mean age was 19.1 years. 2. The incidence was 5.9 percent of all 797 catheterized congenital heart disease cases. The pulmonary valvular stenosis was 30 (68.3%), infundibular 7 (14.6%) and combined 10 (21.6%) cases. 3. The correlation between electrocardiogram and hemodynamic data were as follows. i) The regression equation between right ventricular sysytolic pressure (RVSP) and height of R wave in V1 lead (RV1) was RVSP=3.32 RV1+48.2: its correlation coefficient was 0.818 and it was very significant (p=0.000). ii) The higher the RVSP, the more the frontal axis of QRS complex shifted to the right side (r=0.55. p=0.001). iii) The RVSP of the groups with positive ECG findings such as p-pulmonale, right ventricular hypertrophy or right ventricular strain were much higher than the RVSP of the groups without such findings (p=0.032.0.000, 0.000). iv) The group with RV1 higher than 20 mm showed much more elevated mean of RVSP than the group with lower RV1 (p=0.000). v) The groups with the above mentioned positive ECG findings showed good correlation with the severity of RVSP which was arbitrarily classified as 49 or less, 50~100, and 100 mmHg or more (chi-square=8.96, 26.69, 19.06; p=0.011, 0.000, 0.000). 4. The group with late occurrence of the maximum intensity of the ejection systolic murmur showed higher mean of RVSP than the group with early peak of the murmur (p=0.014). 5. The means of RVSP of the groups with chest X-ray findings such as decreased pulmonary vascularity, were much higher than the means of RVSP of the groups without such findings (p=0.000, 0.005, 0.015). The groups with above mentioned positive chest X-ray findings showed good corelations with the severity of RVSP which was classified as above limits (chi-square=7.55, 10.94, 13.36; p=0.022, 0.004, 0.001). 6. Combined pulmonary valvular and infundibular stenosis showed more severe systolic pressure gradient and higher mean of RVSP than the isolated types (p=0.000).
