The authors studied 126 cases (90 patients) of proven avascuar necrosis of femoral head inadult during theperiod from Jan. 1975 to May 1982 at Kyung Hee University Hospital. The results were as follows; 1. The sex ratiowas 63 males to 27 females and the peak incidence of age was in the fifth decade. 2.Among the 90 patients, thecause and conditions associated with avascular necrosis were idiopathic in 33 cases, femoral neck fracture in 32cases, chronic alcholism in 9 cases, anti-inflammatory drugs abuse in 6 cases, corticosteroid therapy in 5 cases,caisson's disease in 2 cases, hip dislocation in 2 cases and macromolecular storage disease in 1 case, in theorder of frequency. 3. Excluding 34 patients of avascular necrosis associaited with trauma, bilateral lesion was36 patients(64.3%) among the 56 patients. 4. The radiographic features in femoral head were variable, such as 118cases of central increased density surrounded by lucent zone, encompassed by dense rim, 110 cases of collapsedarticular cortex and 16 cases of intact articular cortex, 91 cases of flattening of femoral head, 79 cases ofcrescent sign, 51 cases of fragmentation of osteonecrotic segment, 47 cases of superimposed degenerativearthritis, 5 cases of patchy increased density, and 3 cases of no radiographic change. 5. The bone scintigraphywith Tc-99m-MDP was performed in 11 patients (15 cases) and its finding in femoral head were 8 cases of increasedradioactivity, 4 cases of mixed increased and decreased radioactivity, and 3 cases of absent radioactivity. 6. Itwas our belief that comparative study of plain radiographs and bone scintigraphy would be useful in earlydiagnosis and tratment planning of avascular necrosis of femoral head.

Computed tomographic findings of 24 cases of cervical tuberculous lymphadenitis were retrospectively analyzed. We classified the CT findings as 4 types: type 1(homogeneous soft tissue density mass), type 2(central low density with peripheral rim enhancement and with preservation of surrounding fat plane), type 3(central low density with peripheral rim enhancement and with obliteration of surrounding fat plane), type 4(large confluent low density mass, so called "cold abscess") As a result, there were 2 cases(8.3%) of type 1, 7 cases(29.2%) of type 2, 9 cases(37.5%) of type 3, 3 cases(12.5%) of type 4, 1 cases(4.2%) of type 1 combined with type 3, and 2 cases(8.3%) of type 2 combined with type 4. So 22 cases(91.7%) revealed central low density and peripheral rim enhancement, which suggest necrosis. The maximum thickness of enhancing rim was above 2mm in all of 64 definable necrotic lymph nodes and above 4mm in 42(65.5%) lymph nodes, suggesting that the wall of necrotic tuberculous lymphadenitis tends to be thick. We conclude that CT is useful not only for the diagnosis but also for the evaluation of the extent and the status of cervical tuberculous lymphadenitis.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

To compare the specific information of each imaging modality of US (7.5MHz, water path system) and galactography, and to appreciate clinical applicability of US as a primary diagnostic method in breast tumor causing nipple discharge, we performed a comparative study of each method in 15 cases of the ductal tumor of breast. To evaluate the demonstrable smallest anatomic unit of the lactiferous system by US, 30 normal lactating breasts were examined prospectively. The visible smallest lactating unit in the normal lactating breast by US is terminal duct lobular unit(TDLU). US is superior to galactography for detection of the mass less than 0.5cm in size with proximal ductal dilatation, and for evaluation of the multiple ductal lesions, in contrast, inferior to galactography for systemic visualization of involving ducts and for the detection of microcalcification. Sonographic diagnosis is limited in detection of small retromammillary masses, peripheral small masses without ductal dilatation and masses in excessively fatty breast. In conclusion US can be a primary diagnostic tool in suspicious breast tumor causing nipple discharge as a non-invasive method but galactography should be combined in the indicated cases.

PURPOSE: This study was undertaken to determine the incidence of chromosome 22q11 deletion in patients with infundibular ventricular septal defect(VSD). METHODS: Sixty-two children with infundibular VSD were included in this study from January 1999 to December 2000. Chromosome 22q11 deletion was confirmed by FISH, using LSI DiGeorge/VCFS region dual color probe(Vysis, USA). RESULTS: Thirty-two patients had conotruncal cardiac defects:tetralogy of Fallot (TOF) in 15; TOF with absent pulmonary valve in 1; VSD with pulmonary atresia in 7; truncus arteriosus in 3; double outlet right ventricle in 2; interrupted aortic arch in 2; transposition of the great arteries in 2. Thirty patients had isolated infundibular VSD without conotruncal cardiac defect:perimembranous infundibular VSD in 15; subarterial infundibular VSD in 9; muscular infundibular VSD in 6. Chromosome 22q11 deletion was observed in 8 patients(male 5, female 3):TOF 2; VSD with pulmonary atresia 4; truncus arteriosus 1; perimembranous infundibular VSD 1. All of the patients with chromosome 21q11 deletion showed typical facial appearance. Low incidence was found of chromosome 22q11 deletion in patients with infundibular VSD without conotruncal cardiac defect than in those with conotruncal cardiac defect(3.3% vs 21.9%). CONCLUSION: These data indicate that a small proportion of isolated infundibular VSD is pathogenetically related to deletion of chromosome region 22q11.

Necrotizing colitis associated with carcinoma of the colon, Known also as obstructive colitis, is a disordercharacterized by anulceration and inflammation of the colon proximal to an obstructive lesion, especiallycarcinoma of the rectosigmoid colon, and in rare instances, leads to actual gangrene of the colon. The authorsanalysed radiologic findings in four cases of necrotizing colitis associated with carcinoma of the colon. Bariumenema disclosed mucosal edema, nodular filling defects, irregularity of the colonic controur and typicalthumbprinting appearance of involved colon proximal to an obstructing carcinoma of the colon. The mechanism ofnecrotizing colitis was briefly reviewed.

Condyloma acuminatum, a benign disease caused by a filtrable virus, occurs predominantly in the perianal andgenital areas. The lesions are noninvasive but are subject to recurrence. In rare instances, a more aggresive formof this disease, known as "giant condlyloma acuminatum" or "Buschke-Lownestein tumor", occures. In this form,infiltration of the lesion into surrounding structures takes place. This tumor has been reported to occurprincipally in the genitourinary tract. The authors experienced a cases of giant condyloma acuminatum originatingfrom rectum in 67 years old male patient which recurred 3 months after electrofulguration.

In the unusual manifestation of right upper lobe collapse confusing with mediastinal or parenchymal mass, both alteration of the pulmonary vessels and shifting pattern of the collapsed lobe to the periphery on supine positionare the key to the diagnosis of it rather than mediastinal or parenchymal mass. The mechanisms of these unusual manifestation s are obscure, however lobar torsion and gravity factor are considered to be a main process. Authors have experienced 2 cases of unusual manifestations of right upper lobe collapse due to bronchogenic carcinomaduring resent 2 years in Kyung Hee University hospital, and prsent radiologic findings.

Supravalvular aortic stenosis may be defined as an obstructive congenital deformity of the ascending aorta whitch originates just distal to the level of the origins of the coronary arteries, and whitch includes a wide spectrum of pathologic changes. A 27 years-old-female was admitted because of further evaluation of known some heart disease. Clinical diagnosis of supravalvular aortic stenosis was made by echocardiography and angiography. We presented a case of supravalvular aortic stenosis with a review of literature.
