In children, snapping knee syndrome and joint pain with the loss of physiological hyperextension strongly suggests a diagnosis of a torn discoid meniscus. We performed arthroscopic meniscectomy to treat torn discoid lateral meniscus on 19 knees and open meniscectomy on 9 knees of 26 children(average age: 10.9 yrs) from September, 1983 to October, 1993 at Guro hospital. According to Ikeuchi's grading system', excellent results were obtained in 14, good in 11, fair in 2 knees and poor in 1 knee which was associated with osteochondritis dissecans. The knees treated by partial meniscectomy showed less Fairbank's radiologic changes than those by total meniscectomy during the average follow-up 4.2 years(minimum 1 year, maximum 7 year 11 months).

There has been few papers regarding the pathologic changes of kidney induced by contrast media, especially in terms of iodine concentration or osmolarity. In order to evaluate histopathologic changes, a series of rat kidneys, after injection of iodinated contrast media, were examined. A total of 220 rats were divided into two groups: those given Urografin-60% by 6.3 ml/Kg(1840mg/6.3ml):those given Urografin-76% by 5ml/Kg(1850mg/5ml). (the same amount of iodine but at different iodine concentration). The kidneys were removed and microscopically examined on 1, 2, 3, 5, 7, 10th days, 2nd, 3rd, 4th, 6th and 12th weeks after injection of contrast media, respectively. The results were as follows: Renal pathologic changes induced by contrast media were congestion and ectatic change of the interstitial vessels, epithelial degeneration and necrosis of the collectiong ducts. Congestion of interstitial vessels and epithelial degeneration and necrosis of the collecting ducts were severe in the higher iodine concentration Urografin-76% group(2100 Osm/Kg H2O) than the Urografin-60% group(1500 Osm/Kg H2O). And above pathological changes persisted for 12weeks without significant interval changes. The authors conclude that the renal damage induced by ionic contrast media becomes more severe in higher concentrations or osmolarities in spite of the same amount of iodine and that the pathologic changes persisted until 12 weeks without improvement.

OBJECTIVE: To determine if birth weight greater than 4000gm can be predicted by ultrasound measurement of abdominal circumference(AC) and if shoulder dystocia in macrosomic infants can be predicted by ultrasound measurement of the difference between the abdominal diameter(AD) and biparietal diameter(BPD). METHODS: A Retrospective study was performed of births occuring from March, 1998 to August, 1999 at department of Obstetrics and Gynecology, College of Medicine, Chung-Ang University. Among neonates of birth weight greater than 4000 gm, 50 cases in that ultrasound examination was done within 2 weeks before delivery were selected for macrosomic group and 50 cases were selected for control group during the same period, among neonate of birth weight from 3100gm to 3900gm. RESULTS: 1) Normal spontaneous vaginal delivery(NSVD) was 41 cases in control group and 30 cases in macrosomic group. Among NSVD, shoulder dystocia was 1 case in 41 cases of control group and was 7 cases in 30 cases of macrosomic group. 2) On ultrasound measurement, 6 cases had AC greater than 35 cm in control group and 45 cases in macrosomic group. Among 30 cases in NSVD was done in macrosomic group, difference between AD and BPD was 2.9 0.271 cm when shoulder dystocia was existed and was 2.1 0.409 cm when shoulder dystocia was not existed. Between the two groups, statistically significant difference was detected. 3) When AC(cutoff value of 35cm) was used for screening of macrosomia, sensitivity for macrosomia was 88.2% and specificity was 89.8% and when AD-BPD difference(cutoff value of 2.6cm) was used for prediction of shoulder dystocia, sensitivity for shoulder dystocia was 66.6% and specificity was 95.2%. CONCLUSIONS: In prenatal ultrasound measurement, AC measurement at third trimester of pregnancy will be a valuable indicator for macrosomia screening. The AD-BPD difference of shoulder dystocia group was greater than uncomplicated group in macrosomia and the AD-BPD difference cutoff value of 2.6cm was significant value statistically.
