Subretinal hemorrhage affecting the macula may occur secondary to a variety of etiologies and often results in significant visual loss. Recently, we removed five subretinal hemorrhage affecting the macula by means of vitrectomy combined with the use of tissue plasminogen activator(20-40ug) to facilitate clot removal throught a small retinotomy. Mean follow up period was 7 months. The significant visual improvement(defined as 2 lines) was achieved in 4 of 5 eyes. The postoperative complications were retinal detachment(1 eye), macular fold(1 eye) and recurrent retinal membrane(1 eye). These results suggested that subretinal hemorrhage affecting the macula can be surgically removed with improvement of central vision.

Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of issues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen(PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy(LHRH agonist) was applied to this patient.

OBJECTIVES: To determine the impacts of Diagnosis-Related Groups/Prospective Payment System (DRG/PPS) on the quality of care in cases of Cesarean section and to describe the policy implications for the early stabilization of DRG/PPS in Korea. METHODS: Data was collected from the medical records of 380 patients who had undergone Cesarean sections in 40 hospitals participating in the DRG/PPS Demonstration Program since 1999. Cesarean sections were performed in 122 patients of the FFS(Fee-For-Service) group and 258 patients of the DRG/PPS group. Measurements of quality used included essential tests of pre- and post-operation, and the PPI(Physician Performance Index) score. The PPI was developed by two obstetricians. RESULTS: Univariate analysis demonstrated significant differences in PPI scores according to the payment systems. With respect to the mean of PPI scores, a higher score was found in the DRG/PPS group than in the FFS group. However, the adjusted effect did not show significant differences between the FFS group and the DRG/PPS group. CONCLUSION: This study suggested that the problem of poor quality may not be related to the implementation of DRG/PPS in Cesarean section. However, this study did not consider the validity and reliability of the process measurement, and it did not exclude the possibility of data omission in medical records.

In recent years, as interest in maintaining beauty and a youthful appearance has grown, filler procedures such as soft tissue augmentation have become more popular. These fillers are sometimes seen as radiopaque shadows on radiographic images, either due to the fillers themselves or because of secondary reactions; such findings may present a diagnostic challenge to dentists. The present report describes 3 cases of dermal fillers observed in panoramic and cone-beam computed tomographic (CBCT) images. All 3 elderly female patients had filler injected into their cheeks and chin area for cosmetic purposes decades ago. On panoramic images, multiple symmetric radiopacities were observed in the facial area; on CBCT, these calcifications were seen in the subcutaneous tissue in various shapes and with varying density. In conclusion, dentists should be aware of the imaging characteristics of dermal filler, and should be able to differentiate dermal filler from other pathological findings.

Cervical incompetence is one of the main contributors to repeated pregnancy loss and preterm delivery. Typically it results in progressive cervical dilatation, leading to a painless second or early third trimester abortion. Emergency cerclage can be used in the setting of advanced cervical incompetence, even when fetal membranes bulge through the dilated cervix. To facilitate the procedure, various techniques have been developed to replace the fetal membranes into the uterine cavity. We performed six successful cases of emergency cerclage combined with amnioreduction in advanced incompetent internal os of cervix (IIOC). Interval from emergency cerclage to delivery was 8.1 +/- 2.4 weeks (range 4-10 weeks) and we delivered viable fetuses in all but one. Hereby we report our experiences with a brief review of literature.

Extrapelvic endometriosis is a fairly rare phenomenon. The majority of extrapelvic endometriosis involves scar tissue following obstetric or gynecologic procedures. Abdominal wall endometriosis secondary to cesarean section is a very rare condition, being reported in less than 0.5% of patients undergoing cesarean section. It has a distinct presentation and treatment. An abdominal mass with noncyclical symptoms is a common presentation. Imaging techniques are nonspecific and needle biopsy may confirm the diagnosis. Wide excision is the treatment of choice for abdominal wall endometriosis as well as for recurrent lesions. A patient with a history of cesarean section presented with a painful, enlarging mass. The pain was cyclic and aggravated just prior to menstruation. The patient was treated with surgical scar excision pathologically confirmed as endometriosis. We present this case with a brief review of literature.

Although tubal pregnancy is increasing, primary ovarian ectopic pregnancy has remained a rare event. However, recent reports suggest an increasing incidence to both tubal and term pregnancies. Ovarian pregnancy occurs within the ovary and on the corpus luteum. Earlier diagnosis is now possible, owing to the availability of highly specific radioimmunoassay for human chorionic gonadotrophin and the development of transvaginal ultrasonography. Clinical and even intraoperative diagnosis is difficult and confirmation may be made only by microscopic examination of the tissue specimen. Current understanding of the etiological factors, classification, possible pathogenesis, clinical presentation, diagnostic steps, reevaluation of diagnostic criteria, preferred management and future fertility are detailed. The therapy is surgical and currently more conservative than in the past, because of improvement in operative laparoscopy. We report a case of primary ovarian pregnancy treated conservatively under laparoscopic surgery with a brief review of literature.

BACKGROUND: There is pressure difference depending on the height of hand position when blood pressure is taken, applying the oscillometric electronic digital BP(blood pressure) monitor. Authors have calculated the degree of BP differences, and evaluated the accuracy and effectiveness of the digital BP monitor comparing with the conventional Mercury Sphygmomanometer. METHOD: Randomized sixty cases consisting of in-patients and hospital workers were subjected for this study. BPs were taken at three different levels-nose level, heart level and knee level-on conventional sitting position applying OMRON Digital Automatic Blood Pressure Monitor and conventional Mercury Sphygmomanometer, and statistical analysis was made. RESULTS: At the nose level, systolic BP and diastolic BP were lower with 23.5mmHg and 18.9mmHg respectively, than at the heart level, while at the knee level, they were higher with 21mmHg and 17.5mmHg respectively, than at the heart level. No actual statistical difference of systolic and diastolic values between OMRON Digital Automatic Blood Pressure Monitoring method at the heart level and conventional Mercury Sphygmomanometeric method. CONCLUSION: Present study demonstrated significant discrepancy of BP values, in systolic and diastolic values, depending on the height of measured finger, when OMRON Digital Automatic Blood Pressure Monitor is applied in taking BP on conventional sitting position. However, no actual discrepancy of BP values was noted between two methods when BP is taken at heart level by OMRON Digital Automatic Blood Pressure Monitor and on brachial artery BP by conventional Mercury Sphygmomanometer. Thus OMRON Digital Automatic Blood Pressure Monitor could take the place of Mercury Sphygmomanometer in taking peripheral BP, which subsequently enable us to estimate central artery BP, which is believed to be better clinical index, through this much more handy electrical oscillometric device in the future.

BACKGROUND: This study was conducted to determine the effects of dexamethasone and MK-801 on the formation of brain edema resulting from a focal ischemic injury by middle cerebral artery occlusion in rats. METHODS: Fifteen Sprague-Dawley rats (220 280 g) were freely allowed to drink and eat until just before surgery. Anesthesia was induced with 4% isoflurane in oxygen and then maintained with 2% isoflurane in oxygen. Ischemic injury was induced by an intraluminal suture with a blunted tip inserted into the internal carotid artery and occlusion of the middle cerebral artery. All rats were divided randomly into three groups. In group I (n = 5), normal saline 1 ml was injected intravenously 10 minutes before MCA occlusion. In group II (n = 5), dexamethasone 3 mg/kg was administered 10 minutes before injury. In group III (n = 5), a N-methyl-D-aspartate receptor antagonist, MK-801 1 mg/kg was injected 30 minutes before injury. Rectal temperatures were monitored during the experiment. After 60 minutes of MCA occlusion, the intraluminal sutures were removed and all the rats were returned to their cages. Their brain were quickly removed and the cerebral hemispheres were sepaerated into ischemic cores and penumbra zones after 1 hour of reperfusion. The separated cerebral hemispheres were dried 7 days at 60oC dry oven. The cerebral water content was assessed by the dry-weight method. RESULTS: In the dexamethasone group, there were no significant changes in cerebral edema formation in both ischemic core and the penumbra. In the MK-801 group, there were significant reductions in the brain edema formation in the penumbra (P< 0.05), but not in the core. CONCLUSIONS: Dexamethasone has no effect on ischemic brain edema; however, MK-801 is effective in the ischemic penumbra zone by reducing of edema formation.
