BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.

OBJECTIVES: Health care workers(HCWs) are more likely to become infected with tuberculosis from patients in the hospital. When HCWs have an active tuberculosis infection, it is possible that they also become a source of infections to other HCWs and patients. METHODS: Tuberculin tests were performed with mantoux method using 5 units of tuberculin by infection control practitioners on Feb. 21, and Mar. 7, 1997. A total of 138 newly employed HCWs including 44interns and 94 nurses were tested. Results of skin test were interpreted by themselves according to the instructions. RESULTS: Among 138 personels, skin tests were negative in 27 personels (19.6%); 4 interns (9.1%) and 23 nurses (24.5%). There were 3 persons (2.2%) who had a history of tuberculosis which had been treated. CONCLUSION: The study showed that approximately 20% of newly employed HCWs had negative tuberculin skin test. Given the possibility of being infected with tuberculosis in the hospital, regular follow up of tuberculin skin test is warranted to protect HCWs,

Accidental or suicidal fatalities of paraquat (Gramoxon) poisong are occasionally seen in the emergency room or intensive care unit in this country. In most cases, respiratory symptoms and eventual death by respiratory distress occur within several days. The most striking pathologic change is fibrosis of the lung due to widespread proliferation of fibroblastic cell. We experience a 21-year-old woman with huge bulla on left lung and diffuse fibrosis in other site, who ingested paraquat 10 months ago. After thoracoscopic removal of bulla, the patient survive without progression of pulmonary complication till now.

Neuroarthropathy has infrequently been associated with diabetic patients. The initial presenting symptoms are in most cases the peripheral neuropathy involving chiefly the sensory components of peripheral nerves, leading to numbness, hyper-or paresthesia, and coldness of the extremity affected. The diabetic arthropathy, once occurred, is apt to show progressive deterioration of the function with destruction of both skeletal and supporting soft tissues Two cases of such arthropathy were presented here, the one was observed in a 29-year-old man with involvement of the left fourth and fifth tarsometatarsal joints and a large ulcer on the dorsal skin of the lesion, and the other in a 35-year-old man with destruction of the right ankle joint. Both of them showed remarkable remission of the symptoms with conservative measures such as arch support, cast immobilization and skin graft.

Zielke introduced new anterior instrumentation by modifying Dwyer system and called it the ventral derotation spondylodesis(VDS) system in 1976. This system is a powerful device and when the excised disc spaces are compressed with it, stable fixation can be obtained. But proper patient selection, meticulous operative technique and good post-operative care are essential to minimize serious complications. No results of this technique had been published in English-language literature until Moe reported the results of 66 cases of Zielke instrumentation in 1983. Zielke instrumentation was carried out in 12 cases of scoliosis;8 in idiopathic scoliosis and 4 in congenital scoliosis, at the Department of Orthopedic Surgery, Seoul National University Hospital, for 16 months from November 1984 to March 1986. Seven cases had been followed for more then 9 months and'following results were obtained. 1. Numbers of vertebrae involved in major curve and numbers of fused vertebrae were 6·3 respectively. 2. Average preoperative curve was 72.7 degrees and immediate postoperative curve was 17.6 degrees with 75.8% correction. There was only 1.0 degree loss of correction with an average follow-up of 14 months (9-16 months). 3. Zielke instrumentation has the advantage of shorter fusion and better correction in thoracolumbar and lumbar scoliosis.

Adenomyotic cyst is very rare disease, their sizes are mostly lesser 5mm. The intrauterine adenomyotic cyst may arise from progressive expansion of cyst due to progressive menstrual bleeding. Authors experienced a case of large adenomyotic cyst within myometrium occuring in a l9-year-old woman, and who was accompanied with endometriosis. The cyst was about 3 x 3em sized, and had chocolate colored thick viscous contents, We experienced one case of adenomyotic cyst which was thought to be degenerated uterine myoma, so we report the case with a brief review of the concerned literatures.

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.
