Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

Interbody fusion was performed on eight cases of lumbar instability;five spondylolisthesis and three spondylolysis. Five cases were operated by anterolateral approach through the retroperitoneal space, and posterior approach on three cases after Cloward. Symptomatic improvement was obtained in almost all cases and complete fusion was observed on the roentgenogram three months later. Ambulation was possible from the immediate postoperative day without external support. While posterior approach has an advantage to observe the nerve root under direct vision, anterolateral approach has the following advantages;It is less destructive to the spinal structures, It can be performed without teasing the neural elements, anterior slipping of the vertebral body can be reduced easily, and its was applicable to the upper lumber level where neural elements qre compact. We believe interbody fusion has definite advantage to obtain strong weight bearing stability than fusion of any other parts of the spine because it has rapid recovery, low morbidity and high percentage of complete cure without disability.

Furfurol(Furfudol), a new anthelmintics, was administered to 7 adults and 21 children (6-12 years old) in total amounts of 15.6 mg(base) for 1 to 3 days. It has proven to be effective against hookworms. The anthelmintic effect against hookworms with a single dose of 15.6 mg of furfurol was similar to that of a single dose of 2.5 gm of bephenium hydroxynaphthoate. However, when a total of 15.6 mg of the base was given to both children and adult, the side reactions were so mild that the drug can be administered for therapeutic regimens in mass treatment. Minor abdominal discomfort was the only common side effect. This is the primary advantage of furfurol as compared with bephenium hydroxynaphthoate. These results have indicated that furfurol is safe in therapeutic dosage and is an effective agent to treat patients infected with hookworms.

Recurrent episode of meningitis in infants and children frequently constitute a frustrating and distressing, both in determination of course and treatment. The authors are reporting a infected case of congenital dermal sinus with dermoid cyst in the subarachnoid space of cauda equina and conus medullaris which was cured after complete removal of cyst and sinus tract.

Recently, the incidence of hematogenous osteomyelitis tends to increase dse to abuse of the antibiotics and resistent organisms to antibiotics. The three main causes of complication to be chronic stage in hematogenous osteomyelitis were failure of early diagnosis, inadequate choice of antibiotics with insufficient duration and insufficient surgical intervention. Furthermore, hematogenous osteomyelitis of fibula in children has low incidence, so the possibility of chronicity is able to be increased because of delayed diagnosis and inadequate treatment. During the period of 10 yesrs extending from 1977 to 1986, we have treated 12 cases of hematogenous fibular osteomyelitis in children and clinical analysis was made about comparison with prevalent hematogenous osteomyelitis of distal femur or proximal tibia. The following results were obtained; 1. The incidence in males was 1.4 times grester than females. 2. The incidence of involved sites was 2 times dominant in Rt, and all cases were observed in proximal and distal metaphyseal area of fibula. 3. Clinical symptomes and signs were pain, local heat, redness and local tenderness in all of acute cases and 70% of chronic cases with sinus formation and pathologic Fx. 4. ESR was elevated to average 42 mm/hr in all acute cases highestly, but highest leucocytosis was observed in subacute case. 5. Definite bone changes in radiologic findings was observed in only subacute and chronic cases, and uptake of radioisotope in bone scan was observed in 2 acute cases, which were all performed. 6. Causative organism was only staphylococcus aureus, and high sensitive antibiotics to taphylococcus aureus were Cephalosprin, Cloxacillin, Amikin and observed resistance to penicillin(82.5%) and tetracycline(82.5%). 7. Early diagnosis, adequate antibiotic choice with sufficient duration and early surgical decompression and drainage were considered to be essential part of management of hematogenous fibular osteomyelitis and preventing its chronicity.

There are two contradictive opinions of the therapeutic administration of Ginseng in the conditions of cerebrovascular accident and/or hypertensive heart diseases. This experimental study was performed to observe the effects of the Ginseng extract on the blood pressure(BP) and intracranial pressure(ICP) at the same time. Seven mongrel cats were used. ICP was measured with epidural ballon and pressure transducer, and BP with intraarterial catheter via female routs. Both were continuously recorded by polygrapher. 1. In a normal condition, a single intravenous injection of Ginseng 100mg/kg induced immediate reduction of BP for 30~45 second. Intracranial pressure, however, showed delayed elevation for 50~60 second. 2. Even in a condition of increased ICP or induced cardiac hypertension, the results were the same as in above-described normal condition.

BACKGROUND AND OBJECTIVES: Studies in patients with mitral valve prolapse syndrome (MVPS) have shown the coexistence of various forms of autonomic dysfunction, and so this is an area that requires further investigation. METHODS AND MATERIALS: The study group consisted of 65 patients (36 men and 29 women), aged 16 to 43 years (mean+/-SD, 28+/-8) with symptomatic, echocardiographically proven mitral valve prolapse (MVPS) who were free of other organic heart diseases and arrhythmias. In a prospective study, heart rate variability (HRV) indexes were calculated from 24-hour Holter recordings obtained during normal daily activity and plasma norepinephine was measured, and then these data were compared among the study group according to clinic heart rate (HR). RESULTS: The study group was divided into below 60 bpm (group 1: n=13), 60 - 80 bpm (group 2: n=36) and over 80 bpm (group 3: n=16) on the basis of clinic HR. These patient groups were matched with respect to age and gender. There were significant difference in SDNNIDX, rMSSD and pNN50 between these groups (p=0.005, 0.009 and 0.002 respectively), and these HRV measures correlated inversely with clinic HR (p<0.01). As clinic HR increased, there was a tendency for plasma norepinephrine concentration to also rise (p<0.05), but there was no statistical significant difference between these groups. CONCLUSION: Our data suggests that MVPS may have subgroups of HRV, reflecting cardiac autonomic modulation, according to clinic HR.
