We measured the bone ingrowth rate on 22 retrieved human cementless porous coated acetabular cups by the help of computer graphics. All the acetabular cups had functioned well, and had had evidence of radiologic bony ingrowth before revising the acetabular cup. The reason for retrieval of the acetabular cups were: one with habitual dislocation, who with stem loosening, and 19 with polyethylene cup wearing. The period from initial surgery to retrieval surgery was 28 months to 108 months(average 56.1 months). All the retrieved porous coated acetabular cups showed macroscophic bony ingrowth, and the ratio of the whole porous surface to bony ingrowth area was showed 1.14% to 92.27% (average 36%).

PURPOSE: We critically evaluated the most appropriate management of renal and perirenal abscess and identified the set of patients who had benefited from conservative management. MATERIALS AND METHODS: Between May 1995 and June 1999, fifteen patients with renal (10 cases) and perirenal abscess (5 cases) were treated in our hospital. Among the fifteen patients, six patients were managed by antibiotics alone, the other nine patients were managed by percutaneous aspiration and antibiotics. Percutaneous abscess aspiration and drainage was done under ultrasound guidance and local anesthesia. RESULTS: On the urine culture, 4 cases had positive urine culture (27%); E. coli was in 3 cases, Klebsiella in 1 case respectively. On the blood culture, E. coli was in 2 cases. On the abscess culture (9 cases were performed), the organisms were identified in 8 cases (89%); E. coli was in 6 cases, S. aureus was in 1 case, S. epidermidis in 1 case respectively. CONCLUSIONS: We suggest that proper antibiotic therapy alone or combined with ultrasound guided percutaneous drainage of renal and perirenal abscesses is a choice of reasonable, safe and effective management in selected patients.

BACKGROUND: Urinary retention is the most common complication after perianal surgery. The authors tried to evaluate the influence of the types and duration of the operation and the types of anesthesia on the incidence of urinary retention. METHODS: The medical and anesthetic records of 106 patients were reviewed retrospectively. They got perianal surgerys after recieving one of the regional blocks; 0.5% hyperbaric bupivacaine 5~8 mg intrathecally, 0.5% hyperbaric tetracaine 5~8 mg intrathecally, or 2% lidocaine 300 mg with epinephrine 5 g/ml caudally. The incidences of urinary retention were compared with each other by Chi-square test and Student t-test, according to the above mentioned points. RESULTS: Fifty percent of these patients underwent urinary catheterization. The incidence of urinary retention after hemorrhoidectomy (56.6%) was higher than that of other anorectal procedures (p<0.05, Chi-square test). The longer operating time was associated with urinary retention (p<0.05, Student t-test). The influence of local anesthetics (bupivacaine, tetracaine, and lidocaine) was absent (p>0.05, Chi-square test), but the difference between spinal and caudal anesthesia was slightly significant (p<0.05, Chi-square test), i.e. the incidence of urinary retention after caudal anesthesia was low. CONCLUSIONS: Short duration of operation, less traumatized perianal surgery, and caudal anesthesia are thought to lead to the lower incidence of urinary retention.

The authors, in this paper, addressed a variety of problems and difficulties which Korean psychiatrists should cope with. The surprising development of neurosciences, splitting of neuropsychiatry into neurology and psychiatry, easygoing attitude of psychiatrists, changes in the delivery system of health care and ill-balanced education of psychiary were listed as causes of or contributors to them. Social bias to psychiatry and regulations from outside are also considered as contributors. Psychiatric education, including medical school, residency training, continuing medical education and psychiatric textbooks, need to be changed in order to enlarge the boundary of psychiatry. Reestablishment of identity of psychiatry and psychiatrist is unavoidable, considering far-reaching new knowledge of neuroscience and gradually invisible borderzone between neurology and psychiatry. The other ways worth while to consider are : the expansion of psychiatrists' activities, development of medical behavioral science to a clinical specialty, creation of new psychiatric subspecialties, and additional training of psychiatric residencies in the primary medical care.

Sexual impotence from positioning on the fracture table is rare complication. We are reporting a case of pudendal nerve neurapraxia associated with pressure from the perineal post of the fracture table in 42 years old male with hip fracture. Historical reviews and suggestion for prophylactic measures are also reported in this paper.
