Consecutive twelve patients' twelve eyes with complicated pars planitis underwent pars plana vitrectomy at our center in the period from January 1988 to December 1990. Patients' ages ranged from 24 to 60(mean 39.9)years and all were male. Nine patients had histories of topical or systemic steroid therapy and at the time of surgery, all eyes were quiet from active inflammation. With various degrees of vitreal opacities, five eyes had macular pucker or membrane only and in other seven eyes, retinal detachments of either tractional or tractional-rhegmatogenous origin were arisen. In the later group, macular hole was associated in two eyes. Surgical procedures combined were membrane peeling(five eyes), scleral buckling(ten eyes), fluid/air-gas exchange(eight eyes), lensectomy(two eyes) and photocoagulation(two eyes). During the follow-up period ranged from four to twenty-one(mean 7.75)months after first operations, the uveitis recurred or continued to be activated in four eyes and as a complication, retinal detachment occurred in two eyes which had macular pucker only preoperatively. One refused reoperation and the other was reattached successfully by second operation. Final visual acuities were improved in eight eyes, stationary in one and worsen in three. The causes of worsen vision were retinal detachment, macular edema and macular slanting by buckle respectively. Preoperatively, the majority of eyes(10 eyes: 84%) had less than 0.09 vision and postoperative vision turned over better than 0.09 in 7 eyes(59%). Although we did not confirm extinguished therapeutic effects of vitrectomy on the pars planitis perse, our results revealed some positve role of surgical intervention in the complicated pars planitis.

BACKGROUND: The elderly is known to have many different clinical laboratory data compared with the young adults. But, in Korea, such study is lacking. METHODS: We gathered 98 healthy elderly cases and 98 healthy young adult controls who have taken periodic health examination from January 1993 to May 1996 at one hospital and we compared the mean of various clinical laboratory data between the two groups. RESULTS: In both sexes, cholesterol, ESR, glucose were significantly higher in the elderly t,han in the controls and direct bilirubin was significantly lower in the elderly than in the controls(P<0.05). In men, albumin, calcium, hemoglobin were significantly lower in the elderly than in the controls and MCV was significantly higher in the elderly than in the controls(P<0.05). In women, alkaline phosphatase, LDH, triglyceride, GOT, GPT, T3,TSH, phosphate were significantly higher in the elderly than in the controls and total bilirubin, protein, uric acid were significantly lower in the elderly than in the controls(P<0.05). WBC count, platelet count, neutrophil count(%), lymphocyte count(%), eosinophil count (%), monocyte count(%), MCH, MCHC, BUN, creatinine, HDL were not significantly different between two groups. CONCLUSIONS: Many clinical laboratory data are different between the elderly and the young adults, and some clinical laboratory data have sexual differences.

Thelazia callipaeda, parasitic in the eye of 24 years old Korean male, was extracted from the left eye of the patient in Seoul, Korea. We confirmed that as T. callipeada morphologically, based on the descriptions of Hsu and other literature. We presents the 7th human thelaziasis case in Korea with the historical review of the literature.

To understand the mode of transmission in clonorchiasis, a survey was made in Kim-hae Goon, South Kyong-sang Do (=Province). The mathematical analysis of the age prevalence was done on the egg positive rates. And another analysis for the comparison was also made to the cited data from two areas, North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do. Some catalytic models of H. Muench (1959) were applied to the observed age prevalence. Because the both parameters, such as force of infection(a) and loss of positivity(b) were considered to be constant for a long period in the surveyed area, the two stage catalytic model by Muench was chosen to the analysis. In the surveyed area, Kim-hae Goon where the egg positive rates were 56.2 percent and 61.2 percent (by Kim, 1974), the constant values of 'a' were found to be 0.051 and 0.089 respectively. In other words, the force of infection was 51, 89 per 1,000 susceptibles. The values of 'b' were found to be 0.006 and 0.005. This means that the rates of disappearance from egg positive cases to negative were 6 and 5 per annum per l,000 positive cases in above area. Therefore, the two catalytic curves were expressed by the following equations, y = 1.133 {e(-0.006t) - e(-0.051t)} and y = 1.047 {e(-0.005t) - e(-0.089t)} respectively. In the cases of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do where the egg positive rates of clonorchis shown as 27.7 percent and 15.2 percent by Shin (1964) and Kim (l974), the curves were expressed by y = 1.769 {e(-0.010t) - e(-0.034t)} and y = 2.857 {e(-0.020t) - e(-0.027t)} respectively. From the above mathematical analyses by age prevalence in clonorchiasis, it was considered that the mode of transmission of clonorchiasis in the surveyed area, Kim-hae Goon presented more rapid pattern than those of North Kyong-sang Do and Ko-yang Goon, Kyong-gi Do.

The objective of cancer screening is to reduce the risk of death, i.e., mortality from cancer among individuals subjected to screening. For cervical and colorectal cancer, the screening test is aimed at detection of preinvasive lesions. Therefore, reduction in the incidence of invasive disease also results from screening. In a national cancer control program, the programs should be orgainzed to ensure that a large proportion of the target group is screened and that those individuals in whom abnormalities are abserved receive appropriate diagnosis and therapy. Agreement should be reached on guidelines to be applied in the national cancer control program. When establishing appropriate cancer screening recommendations several factors should be considered. ① For establishing the starting age, age-specific incidence and mortality rate, life lost person-years, and cost-effectiveness can be considered. ② For frequency of screening, it is necessary to understand the natural history of disease. ③ For choosing the best test tool, sensitivity and specificity, compliance, cost, and adverse effects can be considered. It seems that doctors' willingness to participate is essential for a successful cancer screening program. They should understand the rationale of cancer secreening, its effectiveness, and the risk.

Vitreous hemorrhages of white rabbit eyes were obtained by the following three methods and their ultrasonographies were checked several times for four weeks. 1 st group: fresh human blood was injected into the vitreous cavity through the sclera, 2 nd group: oxalated human blood was injected into the vitreous cavity in the same way, 3 rd group: a 26 gauge needle was inserted into the vitreous cavity and retinal vessels were mechanically ruptured to cause vitreous hemorrhage. Ultrasonography of the above groups revealed no definite differences between groups, but a high echo from the vitreous hemorrhages in initial stage changed to several low echoes in later stage. This fact was well matched with funduscopic observation for gradual absorption of the vitreous hemorrhage.

Papillary cystadenoma of the epididymis is a rare benign tumor that represents the epididymal component of von Hippel-Lindau Syndrome. A case of epididymal papillary cystadenoma is presented in a 36 years old man. He also had pancreatic cysts, the pancreatic component of von Hippel-Lindau syndrome. His younger brother, who died of intracranial hemorrhage at age 27, revealed hemangioblastoma of the cerebellum, angioma of the retina and renal cell carcinoma on radiologic studies. These findings suggest familial occurrence of von Hippel-Lindau syndrome.
