In order to observe the differences in fixability and stability of the acetabular cup through the differences in cup size in relation to the size of acetabular reaming, we analyzed 75 cases of porous coated acetabular cup of Harris-Galante type which be followed up more that two years. All cases were divided into two group ; the first group (On line fit :45 cases) used with acetabular cup equal in size to the last reaming size and the second group (Press fit : 30 cases) used with acetabular cup 2mm larger than the last reaming size. For initial stability, all cases were fixed with acetabular screws. Both groups were analyzed for presence of gap, change of acetabular inclination, presence of radiolucent line, degree of displacement of vertical distance, stability and clinical results. The results were as follows; 1. The average Harris hip score was improved from 55.8 points preoperatively to 90.2 points postoperatively in the first group, from 56.9 points to 91.2 points in the second group, Clinical results are excellent in 39 cases, good in 4 cases, fair in 2 cases in the first group, and excellent in 29 cases and good in 1 case in the second group. 2. The gap between the acetabular cup and acetabulum was found initially at 17 zones in the first group but no gap at final follow up. In the second group, the gap was found at 23 zones and finally remained less that 1 mm gap was found at 3 cases in zone B1. 3. No radiologic instability of acetabular cup by Martell evaluation was noted in both 1st and 2nd group. Our data suggests that initial gap between acetabular cup and acetabulum in microporous coated acetabular cup were replaced with new bone and also, radiologic stability and good clinical results could be obtained in the second group used with acetabular cup 2 mm larger than the last reaming size.

PURPOSE: Congenital anomalies are known as a major cause of neonatal death with prematurity and birth injuries. We surveyed the incidence of congenital anomalies among livebirths and stillbirths delivered at our hospital, and detected in neonatal and postneonatal period. METHODS: The statistical study was done about congenital anomalies among 9,569 deliveries (9,438 livebirths and 131 stillbirths) at Ulsan University Hospital during the periods of 5 years from Jan 1992 to Dec 1996. We reviewed delivery and newborn record, OPD chart, admission chart retrospectively. We investigated the incidence of congenital anomaly according to each year, period, outcome of delivery, sex, birth weight, gestational age, maternal age, Apgar score, multiple pregnancy, and each system. RESULTS: 1) The overall incidence of congenital anomalies was 5.0% (481 cases) among 9,569 deliveries. The annual incidence was 4.5% in 1992, 5.1% in 1993, 5.2% in 1994, 5.8% in 1995, 4.7% in 1996. 2) The incidence of congenital anomalies detected in neonatal period was 3.5% (333 cases) and 1.5% (148 cases) in postneonatal periods. 3) The incidence of congenital anomalies was 4.9% among live births and 9.2% among stillbirths. 4) The incidence of congenital anomalies was 5.3% in male and 4.7% in female. 5) The incidence of congenital anomalies among the babies, below 2,500g of birth weight was 7.7%, between 2,500g and 3,999g was 4.7%, and over 4,000g was 6.8N. 6) The incidence of congenital anomalies among the babies, below 32 weeks of gestational age was 12.9%, between 32 weeks and 36 weeks was 7.4%, between 37 weeks and 41 weeks was 4.7%, and over 42 weeks was 5.1%. 7) The babies born to mothers younger than 20 years of age have anomalies in 7.1%, mother between 20 years of age and 35 years of age in 5.0%, and older than 35 years of age in 6.5%. 8) The incidence of congenital anomalies according to Apgar score among live births between 0 and 3 was 9.8%, between 4 and 6 was 6.0%, and between 7 and 10 was 5.0%. 9) The incidence of congenital anomalies according to multiple pregnancy was 8.6%. 10)The systems of congenital anomalies in order of incidence were as follows; The digestive system (25.6%), the cardiovascular system (22.1%), the genitourinary system (18.9%), the musculoskeletal system (15.5%), the skin and soft tissue (11.7%), the central nervous system (1.6%), the respiratory system (l%), the others (3.6%). CONCLUSIONS: Regular examination and screening on congenital anomaly is required from newborn period to infant and childhood. In view of these considerations, the incidence of congenital anomaly may be increased more than the past reports because of development of recent diagnostic techniques.

Multicystic dysplastic kidney is the most frequent cause of abdominal mass in the neonate, but its presentation is variable depending on the size of cystic kidney, state of the opposite kidney and associated anomalies. multicystic dysplastic kidney also represents a spectrum of pathology from unilateral multicystic kidney through segmental and focal multicystic dysplasia to bilateral multicystic kidney. Herein we report 5 cases of MCK with different presentation and histology, a bilateral MCK associated with horseshoe kidney, a large MCK with uremia, a focal segmental MCK with contralateral UPJ obstruction, a small focal segmental MCK with contralateral megaureter and a small MCK detected by ultrasonogram for localization of impalpable testis.

Chemotherapeutic agents were evaluated for their effect on the development of urinary bladder tumors, induced by N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) in female Sprague-Dawley rats. For 16 weeks, 0.05% BBN was administered orally, and then chemotherapeutic agents (adriamycin and cisplatin) were injected intraperitoneally for 12 weeks. In our preliminary experimental series, an experimental bladder tumor model induced by BBN was useful in evaluating the effectiveness of chemotherapeutic agents. Cisplatin appears to be effective in inhibiting precancerous histologic changes and carcinoma in rat urinary bladder mucosa by BBN. However, the effectiveness of adriamycin was inconclusive.

Arthroscopic repair of an isolated teres minor tendon tear without associated shoulder joint pathology has not been reported in the literature. We report on a case of isolated teres minor tendon tear after trauma. The patient complained of severe shoulder pain and progressive limited range of motion 4 months after the injury. Magnetic resonance imaging showed a full-thickness tear of the teres minor tendon at its musculotendinous junction and arthroscopic repair was performed. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. Here, the authors report this case and provide a review of literature.

Intracranial hemorrhage is the most common neuropathologic finding in premature infants. But in full-term infants, it is less common and rarely causes death. We found out intracranial hemorrhages in 21 full-term neonates by real-time neurosonography and concluded as followings. 1) Among 21 neonates, 17 infants were male and 4 infants were female. 2) In 11 (52.3%) infants the hemorrhage was detected within 7 days after birth. 3) The intracranial hemorrhage was not related with delivery type nor Apgar score. 4) In 13 cases (61.9%) the hemorrhage was in the subependymal germinal matrix and the degree was Grade I. 5) Precipitating or associated factors were asphyxia, pneumonia, ventilator care, RDS and congenital heart disease. 6) Symptoms and signs were seizure, apnea, lethargy, cyanosis, jaundice, anemia or bulging fontanel.

From Nov. 1990 to Dec. 1994, authors have experienced 12 patients(13 eyes) diagnosed as posterior lens dislocation. The clinical results were evaluated in aspeets of sex and age distribution, preoperative and postoperative visual acuity, operative method, postoperative complication. The average age of patients was 57.8 years old and average follow-up period was 11.5 months. Male were 58%. They have history of ocular trauma in all 13 eyes. Dislocated lens was removed by extraction with lens spoon or loop through corneoscleral incision in 3 eyes and pars planar vitrectomy followed by lens lift with needle and extraction through corneoscleral incision in 7 eyes or with perfluorocarbon liquid and extraction with spoon or loop in 3 eyes. The best corrected visual acuity was improved in 10 eyes and remained the same in 2 patient(3 eyes) who was visited our hospital more than 10 years after dislocation and associated with optic nerve atrophy, macular degeneration, bullous keratopathy. Postoperative complications included glaucoma, choroidal detachment, retinal detachment, persistent vitreous inflammation, vitreous hemorrhage, bullous keratopathy.
