To study the development of distraction at the fracture site according to inaccurate insertion of the distal screw in treatment of femoral shaft fracture with interlocking intramedullary nail, we prepared 24 femoral bone model, fixed them with interlocking intramedullary nails after artificially making transverse fracture or spiral fracture at mid 1/3 of femoral shaft and distal 1/3 of femoral shaft. The cephalocaudal insertion angles of the distal screws ranged from 5.2 to 45.4. As the insertion angles increased, the distances between the fractured sites ranged from 0.1 to 8.2mm. Distractions splited more than 5mm were seen in the average insertion angle of 34.3+/-9.4 (28.2 -45.4 ). When the insertion was made few millimeter proximal from the center of the distal screw hole, which was parallel to the transverse section of the femur model, fracture distraction ranged from minimum 1.8mm to maximum 5.0mm. In conclusion, the cephalocaudal insertion angle or location of the distal screw can be reason for the distraction between the fractured sites in internal fixation with intramedullary nail in long bone like femur. To prevent the distraction of fractured site, it is important to make the insertion of the distal screw parallel to the transverse section of the femur and to insert into the center of the screw hole.

Journal of Korean Neurosurgical Society 1976;5(2):279-284
Occult meningocele is a cystic type of spinal dysraphism derived from developmental fusion defect during early fetal life. It is well known its common, but remarkably less than of myelomeningocele in incidence, combinations with other anormalies. A 11-year-old boy suffering from waddling gait and equinovarus foot deformity for 6 years, is presented. He has not any external protruded mass, hypertrichosis or abnormal pigmentation around his low back. He also has no evidence of neurofibromatosis or enlarged head. Pain spinal films show widening of intervertebral foramina and interpedicular distance, and spina bifida. With myelography using 90ml of Pantopaque, huge ectatic sac accompanying with multiple outpocketings of meninges like stocked tail is well demonstrated. Neurosurgical operation was not indicated. Operation for the correction of the foot deformity were performed by orthopedician.

The computed tomography (CT) number is closely related to hematocrit level according to many of the previous reports. We measured the CT number in various organs, such as the frontal white matter, basal ganglia, occipital white matter, cerebrospinal fluid, liver, abdominal aorta, spleen, kidney, and psoas muscle. We correlated the CT numbers of the organs with hematocrit levels which were graded into 10% increments (20.0-29.9%, 30.0-39.9%, 40.0-49.9%). Thus the change of CT numbers in various organs according to the hematocrit level was analyzed. The increased CT numbers according to the 10% increment of hematocrit in the frontal white matter, basal ganglia, occipital white matter, liver, abdominal aorta, spleen, and psoas muscle were 1.3, 1.5, 1.6, 3.3, 5.3, 3.8, 2.4 respectively. Even though the CT numbers of the cerebrospinal fluid and kidney were not influenced by hematocrit level the CT numbers in most of the there organs postitively correlated with hematocrit level. Therefore, it was concluded that in the differential diagnosis using CT numbers, the hematocrit level of patient must be taken into consideration.

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.

Trichinellosis is a parasitic zoonosis of public health importance. It is caused by Trichinella spiralis which has a wide host range including humans. In the present communication, the ELISA technique was employed on a total of 803 blood samples from 7 selected pig breeding farms in 1996 for diagnosis and surveillance of trichinellosis. Out of the entire 803 samples, nine were found to be suspected while one was positive by ELISA. But western blot analyses employed for further confirmation have shown that all of 10 samples did not react to larval excretory-secretory product antigens. These results indicate that pig breeding farms included in the present study are free from trichinellosis. However, it does not mean Korea is free from trichinellosis since human trichinellosis has recently been reported. The necessity of continued surveillance for trichinellosis in both pigs and wild animals was discussed.

Journal of the Korean Pediatric Society 1980;23(7):534-542
Clinical observation about 34 infants of gestational diabetic mothers(IGDM) and 4 infants of overt diabetic mothers(IDM) was attempted on the 388 large infants(above 4kg.) among 9,263 neonates, who were delivered at the Ilshin Women's hospital during 19 months from Jan. 1977 to July 1978. Birth characteristics, maternal history and perinatal complications were compared with control group of non-diabetic mothers. The results were summerized as follows : 1. The frequency of large infants was 4.2%. Among the large infants, IGDM were 8.8% and IDM were 1.0%. 2. The mean birth weight of IGM ranging in gestational age from 38 to 44 weeks was 4,240gm. No relationship between gestational age and birth weight was noticed. 3. The clinical features of IGDM were asymptomatic hypoglycemia (14.7%), hyperbilir ubinemia(11.8%), Apgar score below 6 at 1min(8.8%), and cogenital mal-formations(5.9%)in order of frequency. But no remarkable difference was noticed between IGDM and control group. 4. Compared with control group, the incidence of gestational diabetic mothers with toxemia and complicated pregnancy was higher. But no diffenence was found about maternal history and other perinatal problems. 5. Among 4 cases of IDM, two with hyperbilirubinemia, Apgar score below 6 at 1 min. and asymptomatic hypoglycemia and one with congenital malformations were noted. One case expired with respiratory distress syndrome.

Fetal cystic hygroma is a rare congenital malformation of the lymphatic system appearing as a single or multiloculated fluid-filled cavity, most often in the neck. A case of fetal nuchal cystic hygroma was diagnosed by Ultrasonography at 22 weeks of gestation and the diagnosis was confirmed at autopsy. We present the case with a brief review of literature.

Two cases of vaginal injury due to Coitus are presented. One is the case of the laceration of midportion of posterior vaginal wall with shock and the other one in the laceration of posterior vaginal fornix and pelvic peritoneum. They are all in multiparity. And a review of literature on vaginal injury due to coitus is made briefly.
