The branch retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Complications such as macular edema, retinal neovascularization, vitreous hemorrhage, epiretinal membrane may be associated. But, the retinal detachment may occur rarely in BRVO patients. We studied the clinical features of retinal detachment associated with branch retinal vein occlusion. We reviewed the medical records of 15 retinal detachment patients associated with branch retinal vein occlusion. Mean age was 54.7 years old and 10 patients(66.7%) were female. Hypertension was associated in 13cases(86.7%). The duration between the development of BRVO and the development of retinal detachment was shorter than 4 years in all cases and shorter than 2 years in 9 cases(60.0%). Retinal break was identified in 14 cases(93.3%), among which 13 cases(92.2%) were located inside the lesion of branch vein occlusion. The epiretinal membrane was frequently combined 8 cases(53.3%). The preoperative laser photocoagulation was done in 4 cases(26.7%). The primary surgical procedures included scleral buckling in 8 cases(53.3%), pars plana vitrectomy in 6 cases(40.0%), and scleral buckling with pars plana vitrectomy in 1 case(6.7%). Three cases(20.0%) required reoperations. The postoperative complications included the progression of cataract in 6 cases(40.0%), iatrogenic retinal tear in 3 cases(20.0%), epiretinal membrane in 2 cases(13.3%), and proliferative vitreoretinopathy in 1 case(6.7%). The anatomic retinal reattachment was achieved in 14 cases(93.5%) and the visual recovery in 11 cases(73.3%).

A study was required to evaluate the prevalence of clonorchiasis among school children in the 7 differnet schools located near the Gumho basin and to determine the effectiveness of the anticlonorchis campaign conducted in that area. Surveys for Clonorchis sinensis and the worm burden in the same areas were compared for the period 1960-1970. Both surveys concentrated on children in grades 1-3 ranging from 6-11 years old. They were examined using primarily intradermal tests with Clonorchis antigen and followed by stool examinations. Stool examinations consisting of the formalin-ether sedimentation(Ritchie, 1948 ) and the Stoll egg-count techniques were performed in those cases which revealed positive and doubtful intradermal reactions. The overall prevalence rate for clonorchiasis was reduced from 13.4 per cent to 4.1 per cent. There was also a significant reduction in the worm burden, suggesting that no clonorchiasis will be found among chileren in the near future. In connection with this survey, the prevalence rate for intestinal helminths in 1960 was compared with 1970. The rate for Ascaris lumbricoides had decreased, while the rates for Trichuris trichiura and Trichostrongylus species had increased. No fluctuation in the rate of hookworm was observed during the past 10 years. Clearly, the present survey denotes a requirement for a combined procedure of health education and mass survey with intradermal testing. It has been found that these methods not only greatly reduce the prevalence of clonorchiasis but also is followed by the marked reductions of the worm burdens of the children examined.

For seven years from 1962 to 1968, fecal specimens of the patients were examined not only for the discovery of intestinal protozoa and helminths, but also to provie data on the incidence of intestinal parasites among the residents of Kyungpook Province, Korea. The Formalin-ether sedimentation, Lugol solution, and Heidenhain's iron-hematoxylin stained films were prepared for the recovery of intestinal parasites. Of 2,414 samples of feces examined, 35.7 percent were found to be infected with one or more species of protozoa. Among six species of protozoa detected, Entamoeba coli was observed most frequently(15.3%) followed by Entamoeba histolytica (11.9%), and then the Enteromonas hominis least often(1 case). For the survey of helminth, of a total of 5,288 fecal specimens examined, 86.7 percent were positive for one or more species of helminths. Trichocephalus trichiurus revealed the highest infection rate (83.6%), while Trichostrongylus orientalis was next (61.6%), and Ascaris lumbricoides was unexpectedly low(40.9%). The incidence for hookworm and Clonorchis sinensis was 22.4 percent and 29.8 percent respectively. Triple infections were found more frequently than double infections, and mixed infections of six or more species of helminths were observed in 3.8 percent of specimens.

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.

The preoperative measurement of adequate nail length is very important for femoral shaft fracture naiTing Operation. To reduce the disadvantages of scanography which are the fracture site pain, motion and radiation hazard, the simple external measurement method of intramedullary nail length was designated through this study. The fifty normal Korean whose bone growth v:as ceased were chosen for this study. And the lengths with the simple external measurement of thigh and scanogram of femur were compared at both side. The lateral roentgenographic view of femur was checked to analysis of anterior angulation at the proximal one third of femur was checked to analysis of anterior angulation at the proximal one third of femur. The following results were: 1. Femoral length was about 24% body height on an average. 2. The distance between the lower margin of the anterior superior iliac spine and the patellar upper pole (SPD) was equal to the distance between the tip of the greater trochanter and the cented of distal subchondral line. 3. Straight intramedullary nail length was 40 to 45 mm shorter than SPD. 4. The roentgenogram revealed that the femur took its anterior bowing by 9 degrees.

Intermittent Exotropia has been treated by various surgical methods such as bilateral medial rectus resection, lateral rectus recession and medial rectus resection of deviating eye, and bilateral lateral rectus recession. However, the outcomes of such operations are unsatisfactory because of high incidence of postoperative undercorrection and overcorrection. Authors have performed a surgical method which is the medial rectus muscle resection of dominant eye and lateral rectus muscle recession of non-dominant eye in 68 patients. Authors considered the outcome successful if patients achieve deviation between 10 PD of exophoria and 5 PD of esophoria, good stereopsis, no suppression and no manifest deviation. The success rate was 83.8% (57/68) and there was no overcorrection over 6 months follow-up. As postoperative complications, 5 cases of temporary turning of face and 3 cases of asymmetric palpebral fissure were seen. Therefore, these results suggest that medial rectus resection of dominant eye and lateral rectus recession of non-dominant eye in intermittent exotropia may be an alternative surgical method for intermittent exotropia. However, further studies are necessary to determine the exact surgical amounts and mechanism of this surgical method.

Epididymal abnormalities have long been found in conjunction with undescended testis. Undescended testis with a patent processus vaginalis are associated with epididymal abnormalities, but the incidence of epididymal abnormalities in descended testis with a patent processus has not been reported. We analyzed the patency of processus vaginalis and epididymal abnormalities of 37 patients(41 testes) treated for undescended testes and 78 patients(79 testes) treated for hydrocele. Epididymal abnormalities ranged from simple epididymal elongation, epididymal angulation, disruption between testis and epididymal tail to more complex forms, such as epididymal/vasal atresia, complete disruption between the testis and epididymal head. Among 38 undescended testis with patent processus vaginalis 27(71%) had an epididymal abnormalities compared to 12 of 37(32%)hydroceles with patent processus vaginalis(P<0,05), and 12 of 38(329b) undescended testis with patent processus vaginalis had complex epididymal abnormalities(epididymal head separation and epididymal atresia) compared to 2 of 37(5%) hydroceles with patent processus vaginalis (p<0.05). Among 37 hydroceles with patent processus vaginalis 12(32%) had an epididymal abnormalities compared to 2 of 37(5%) hydroceles with incompletely patent processus vaginalis(P<0.05). These data suggest that epididymal abnormalities probably contribute to both testicular maldescent and closure of processus vaginalis.

PURPOSE: We assessed the feasibility of testis-sparing surgery in children with testicular tumors. MATERIALS AND METHODS: Twenty-five pediatric patients who had a testicular tumor were enrolled for retrospective analysis. Testis-sparing surgery was planned in the cases with clinical features that preoperatively suggested the tumors to be benign, which was later determined intraoperatively by frozen section examination. The preoperative-fetoprotein (AFP) and transscrotal ultrasound (US) were evaluated along with the final pathology. We reviewed the immediate and late surgical complications, as well as the tumor recurrence after surgery. RESULTS: Teratoma, epidermoid cyst, yolk sac tumor, and Leydig cell tumor accounted for finding in 40%, 32%, 24%, and 4% of the patients, respectively. Based on the preoperative US, 18 patients had benign-looking tumors. According to the age-matched AFP references, 17 patients showed normal ranges preoperatively. Out of 14 patients, whose US and AFP level suggested the tumors to be benign, 10 (71.4%) were eligible for testis- sparing surgery on retrospective review. Testis-sparing surgery was performed in 5 patients, who showed the same pathology in frozen sections (3 epidermoid cysts, 2 teratomas). None of the 5 patients exhibited perioperative complications, and no recurrence or atrophy was observed at a mean follow-up of 39.8 months. CONCLUSIONS: Out of 14 patients, whose US and AFP analyses were available, 10 (71.4%) were eligible for testis-sparing surgery. Testis-sparing surgery was done in five out of the 10 patients without any complication or recurrence. Testis-sparing surgery is a feasible option in children with testicular tumors if the AFP level is within a normal range and the US suggests benign characteristics.

Endonasal DCR has been reported for the advantages of lack of a cutaneous scar and short operating time but that the surgical success rates were lower than conventional method. We have performed endonasal DCR and had follow-up of at least 6 months in 107 patients who had been diagnosed with lacrimal pathway obstruction, and also surveyed the age, sex, sac size and nasal cavity abnormality to evaluate the factors related to success rate. Primary success rates were 82.2%(88eyes) and higher success rates were noted in younger age, man and large sac but not significant. But. the cases associated with nasal cavity abnormality as septal deviation, middle turbinate hypertrophy, ethmoiditis and polyp showed poor surgical results due to membranous ostium closure, formation of granuloma within the ostium, and formation of cicatrix with the middle turbinate.(P<0.05) Improvement of success rate may be owing to appropriate preoperative evaluation, proper management of nasal cavity abnormality preoperatively and intraoperatively, and show consider the conventional method in cases of that lower success rate are predict.
