The stress fracture is a disease which results from the application of an abnormal stress to the normal bone by the action of the constant and repeated muscular pull. Stress fracture has been reported in the long bones of the lower extremities and in the pelvis, however, of recent days, it is reported in the long bones of the upper extremities. In the past, stress fractures were seen mainly in military personnel. However, in recent years, a significant number of stress fractures have been seen in sports due to the great popularization of sports. 48 cases of stress fractures in 43 patients who have been diagnosed and treated at the Department of Orthopedic Surgery of National Police Hospital, from Jan. 1984 to Jan. 1986, were analysed. The following results were obtained: l. Occurrence ratio by sex, there were more male patients than female(M:F=2: 1). Age distribution was various from 14 to 9, but we could see high frequency occurred in the teenage. 2. The order of occupational distribution was as follows; Athletes were extremely high, 25 (58. 1%), combat policeman, 16(37.2%) and others, 2(4.7%). 3. Most of the stress fractures were in the tibia, an incidence of 57.3%. 4. The period from the beginning of exercise to the occurence of the stress fracture varies from 6 days to 2 years. 4. Although initial X-ray film results being negative, we think that it necessary to check bone scan and follow-up X-ray study.

Dislocations of the toes are comparatively rare. The majority of the these injuries occur in the great toe at the metatarsophalangeal joint. Dislocations of the interphalangeal joint of the great toes are extremely unusual, especially interphalangeal dislocation of the grcat toe with interposition of a sesamoid bone is extremely rare. Authors wishes to report two cases of interphalangeal dislocation of the great toe with interposition of the interphalangeal sesamoid.

PURPOSE: Biliary dyskinesia was considered as a wastebasket of quasi-biliary disease which could not be clearly explained under the basis of morphologic pathology. This entity was a source of confusion because of misconception and poor understanding. Recent introduction of biliary manometric technique enlightened some of these disorders. We evaluated the cholangiographic morphology of these disorders to clarify and to characterize the some characteristic findings, subsequently in order to help the diagnosis. MATERIALS AND METHODS: Five cases were confirmed by this technique as sphincter of Oddi dysfunction for last 13 months. All patients were female and age range was 53 to 75 years old. All patients were suffered from intermittent and recurrent biliary type pain. RESULTS: ERCP showed five common findings. The common bile duct was dilated over 12ram in all patients. Different from recurrent pyogenic cholangiohepatitis, intrahepatic ducts were proportionally dilated as extrahepatic ducts, in four patients and they branched normally and ductal wall was smooth. Transient or persistent meniscus sign was observed in four patients. All patients showed delayed emptying of contrast media from the common bile duct into the duodenum. Following IV injection of cholecystokinin, persistent meniscus disappeared and contrast media inflowed into the duodenum. CONCLUSION: Identification of all or some characteristic cholangiographic findings may eliminate a cumbersome and painful biliary manometric test for the diagnosis of sphincter of Oddi dysfunction.

PURPOSE: This study investigated the influence of patent ductus arteriosus (PDA) and its treatment on incidence and progression of retinopathy of prematurity (ROP). METHODS: The authors retrospectively reviewed the medical records of 408 infants who underwent screening examinations for ROP at the Neonatal Intensive Care Unit of our hospital. RESULTS: The total incidence of ROP was 23.5% (96 out of 408) and the patients that needed treatment were 7.4% (30 out of 408). The mean birth weight and gestational age was 1406.1 grams and 30.67 weeks in patients without ROP, and 979.8 grams and 27.46 weeks in patients with ROP, respectively. In both total and very low birth weight (VLBW) patients, the incidence of ROP was higher in the PDA group than the non-PDA group, but the PDA group was an independent risk factor only in the VLBW group (p = 0.033). The incidence of threshold disease was not significantly different between the PDA and control groups (p = 0.757). There was no significant difference of incidence of ROP and threshold disease among the 3 treatment groups for PDA. CONCLUSIONS: In VLBW patients, the presence of PDA increased the risk of ROP and its progression, thus more attention is needed for PDA patients. However, there was no significant difference in ROP incidence and progression according to different PDA treatment methods.

We have clinically evaluated 40 cases of high myopia(47 catarctous eyes) with an axial length of over 26 mm which were treated with ECCE and posterior chamber intraocular lens implantation from January 1987 to June 1990 at the 51. Mary's Hospital in the Department of Ophthalmology of Catholic University Medical College. The results were as follows: 1. Most common axial length was from 26.00 mm to 26.50 mm in 24 eyes(51.5%)and most common anterior chamber depth was from 2.51 mm to 3.00 mm in 22 eyes(48.6%). 2. The most common associated diseaes was vitreous opacity(19 eyes: 40.4%). 3. Posterior chamber lens power ranged from +10.00D to +14.00D, and the most frequently implanted posterior chamber lens power was +10.50D. 4. Postoperative corrected visual acuity was the same as preoperative corrected visual acuity in 46 eyes(97.9%) and improved up to 0.5 or more in 31 eyes(66.0%).

The metastatic neoplasm is one of the common neoplasms in the orbit. It is also reported that the commonest origin of the metastatic neoplasm to the eye is the lung in men and the breast in women respectively. The authors experienced a case of metastatic papillary adenocarcinoma to the choroid posteriorly of both eyes. The metastatic lesions were also found in brain, cervical lymph node, lung and breast. The origin of the cancer was obscure in this study and could not be identified.

We injected tPA into the anterior chamber of 43 pesudophakic eyes with moderate to severe fibrinous membrane which had developed following cataract surgery from January, 1990 to August, 1990 at St. Mary's hospital. The results were as follows: 1. Intraocular tPA injection was resulted in complete fibrinolysis within 1 hour in 38 of 43 eyes and patial fibrinolysis in 5 of 43. 2. No corneal endothelial cell loss was found, and tPA did not appear to cause a significant rise in intraocular pressure. 3. Complications of tPA injection included mild, transient, periocular pain(3 eyes), anterior chamber fibrin debris(2 eyes) and anterior chamber hemorrhage(1 eye). The results indicated that tPA is dramatically effective for the clearance of fibrinous membrane after cataract surgery.

PURPOSE: Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family. PlGF is implicated in several pathologic processes, including the growth and spread of cancer and tumor angiogenesis. The aim of this study was to evaluate the expression and the clinical implications of PlGF in colorectal cancer. METHODS: In order to ascertain the clinical significance of PlGF expression in colorectal cancer, the researcher analyzed the expression pattern of PlGF by using an immunohistochemical method and attempted to establish if a relationship existed between PlGF expression and microvessel density (MVD), and subsequently between PlGF expression and the predicted prognosis. A total of 83 patients with colorectal cancer were included for immunohistochemical staining. Clinicopathological characteristics were defined according to the tumor-node-metastasis (TNM) criteria of the Union for International Cancer Control. Clinicopathologic factors, such as age, sex, histological types of tumors, tumor cell grade, TNM stage, lymphovascular invasion, and lymph-node metastasis, were reviewed. RESULTS: In this study, the PlGF protein expression level was significantly correlated with MVD, patient survival, and clinicopathological factors such as lymph-node metastasis, TNM staging, lymphatic invasion and vascular invasion. CONCLUSION: PlGF may be an important angiogenic factor in human colorectal cancer, and in this study, PlGF expression level was significantly correlated with positive lymph-node metastases, tumor stage, and patient survival. These findings suggest that PlGF expression correlates with disease progression and may be used as a prognostic marker for colorectal cancer.
