Patients with severe acetabular bony deficiency in total hip revision arthroplasties need the use of autogenous or allogenic bone grafts. The Authors performed 28 cases of total hip revision arthroplasties between June 1991 and January 1995 with femoral head allograft for acetabular bony deficiencies and evaluated the clinical and radiological results according to AAOS classification. The clinical result was evaluated by D'Aubigne and Postel score. The mean score was improved from 3.9 points to 5.1 points at follow-up. In radiological evaluation, osseous union of graft was achieved within 12 month and rerevision were performed in two cases (92.8% survival rates) but radiological radiolucent line in at least one zone was seen in five hips in two year follow up. In conclusion, the results of hemispherical microporocoat cup with allogenic bone in segmental or cavitary defect using with acetabular reinforcement ring in combined deficiency were encouraging to date. Success rate of allograft reconsruction of the acetabulum results from a variety of acetabular defect. In our studies, only 40% showed stable bony fixation over short period.

Cervical tuberculous lymphadenitis is a commonly encountered disease, expecially in adults, Differentiation from other lymphadenopathy and benign conditions such as cystic neck masses is important. CT findings of tuberculous lymphadenopathy in the abdomen and thorax are reported in many literatures. But there are only a few articles concerning cervical tuberculous lymphadenopathy. The authors retrospectively analyzed CT findings of 33 cases with cervical tuberculous lymphadenitis regarding distribution, contour, enhancing pattern, changes of adjacent fascial plane, and dermal and subcutaneous manifestations. We concluded that the presence of conglomerated nodal masses with central lucency, thick irregular rim of contrast enhancement and inner nodularity, varying degree of homogenous enhancement in smaller nodes, dermal and subcutaneous manifestations of inflammation such as thickening of overlying skin, engorgement of the lymphatic and thickening of adjacent muscles, and diffusely effaced fascial plane are suggestive of tuberculous lymphadenitis. However, some CT patterns of tuberculous adenitis may be seen in other disease; for example, enhancement can occur in hyperplastic nodes, vascular metastasis(thyroid, melanoma, and hypernephroma), lymphoma, granulomatous disease, and Castleman's disease.

The authors present a case of posterior fossa arachnoid cyst associated with syringomyelia. A 58-year-old woman was admitted to our hospital due to progressive headache, gait disturbance, and pain at the left upper extremity. Magnetic resonance(MR) image showed a huge retrocerebellar arachnoid cyst associated with syringomyelia from the second to the sixth cervical vertebral level. After decompression of the posterior fossa including removal of posterior lip of foramen magnum and lamina of the atlas and fenestration between arachnoid cyst and subarachnoid space, the patient's symptoms were improved and the arachnoid cyst and syrinx were shrunken on follow-up MR imaging. The authors discuss the pathogenesis of the syringomyelia associated with a huge posterior fossa arachnoid cyst and the management option.

Fournier described five patients with gangrene of male external genitalia in 1883 and emphasized three characteristics: (1) abrupt onset in young healthy male, (2) rapid progression to gangrene,(3) absence of discernible cause. But more recent reports described genital gangrene as occurring in any age group and 4 patients in our cases, the mean age was 46 years with an age range of 31 to 59 years. Predisposing causes were as follows: case 1. prostatic calculi, Buerger's disease, case 2, perianal abscess, case 3, diabetes mellitus, case 4, tuberculous spondylitis accompanied by paraplegia and bed sores, liver cirrhosis. The duration of symptoms prior to the development of gangrene varied between 4 to 10 days. The cultured organisms were as follows : case 1. Alpha-hemolytic streptococcus, case 2. E. coli, Alpha-hemolytic streptococcus case 3. Alpha-hemolytic streptococcus, case 4, Mycobacterium tuberculosis, proteus species. Reconstructive surgery of defected scrotum was performed postoperative 8 to 41 days (mean 28.7) and total admission period was 25 to 83 days (mean 46 days).

This study was carried out to determine the accuracy of Doppler echocardiography for predicting the pulmonary arterial pressure from right ventricular systolic time intervals in 52 patients with ventricular septal defect. The diagnosis of ventricular septal defect was made by cardiac catheterization and angiocardiography at Dong San hospital, Keimyung University during the period of one year from jan. 1988 to Dec. 1988. Doppler measurements of acceleration time (AT), right ventricular ejection time (RVET), right ventricular preejection period (RPEP), AT/RVET, and RPEP/AT were compared with pulmonary arterial pressure (PAP), measured by cardiac catheterization. The patients were divided into 3 groups : PAP< or =30mm Hg, PAP 31-59mm Hg, PAP??0mm Hg. The following results were obtained. 1) In the groups of PAP< or =30mm Hg, AT was 0.12+/-0.01sec, AT/RVET was 0.47+/-0.07 and RPEP/AT was 0.50+/-0.05. 2) In the groups of PAP> or =60mm HG, AT was 0.06+/-0.01sec. AT/RVET was 0.28+/-0.05. RPEP/AR was 1.51+/-0.21. As the level of PAP increased, Doppler AT, AT/RVET and RPEP/AT showed significant change(P<0.001). 3) The Doppler AT showed relative high correlation(r=-0.76) with PAP measured by cardiac catheterization in all group. 4) The Doppler AT/RVET showed correlation(r=-0.70) with PAP. 5) The Doppler RPEP/AT showed high correlation(r=0.91) with PAP. The Doppler echocardiography was easy to apply in all age groups, and was found useful for detecting pulmonary hypertension in ventricular septal defect and for the follow-up check of the patients. It may help to determine the optimal time for surgery and evaluation of the treatment.
