In these days, computing environment turns to web environment and a lot of hospitals build information system. A medical services through the web provide patients and doctors with convenience and help experts to communicate with each other. Initially, web provided static text information, but nowadays needs of interactivity between client and server is increasing. In order to diagnose heart diseases, we use 12 channel ECG, stress ECG, holter ECG, etc. These data are a lot of correlation with each other but there are little system managed them with integration. To enhance management efficiency and share medical information, it is necessary to develop integrated ECG management system based the web. In this paper, we use common object request broker architecture(CQRBA) to implement the system. The CORBA is to apply object oriented concept to web. We can implement application easily and reduce costs to maintain and repay because server objects and client objects exist independently. We developed a System to integrate these data using network and to raise management efficiency. we focus on the performance of object web and the implementation of ECG management system based on the web.

PURPOSE: Intravitreal injection of bevacizumab (Avastin(R)) can lead to several intraocular complications including endophthalmitis, hemorrhage and inflammation. We present one case of acute anterior uveitis with hypopyon in an HLA-B27(+) patient following intravitreal injection of bevacizumab. CASE SUMMARY: A 40-year-old male with known central retinal vein occlusion presented with redness and decreased visual acuity in the left eye. Symptoms had developed 4 days earlier after the sixth intravitreal injection of bevacizumab in that eye. The patient had a marked anterior chamber reaction with hypopyon and posterior synechiae. Nine days after onset, similar symptoms in the left eye occurred in the uninjected right eye. Through examination and clinical manifestations, we diagnosed acute anterior uveitis associated with HLA-B27 positivity. The patient was treated with 1% prednisolone acetate, 0.5% moxifloxacin and 1% atropine in both eyes and all symptoms had resolved after 6 weeks.

Pseudomonas scleral abscess is characterized by acute onset and rapid progression to scleral perforation, and has a subsequent risk of endophthalmitis. After control of infection with appropriate antibiotics, graft surgery should be performed for reinforcing the defected sclera. We performed a scleral homograft on the eye with large necrotic sclera caused by Pseudomonas aeruginosa infection after pterygium excisIon. And the results were remarkably good.

OBJECTIVE: The purpose of this study was to evaluate the therapeutic efficacy and toxicity of high dose cisplatin-cyclophosphamide combination chemotherapy on patients with primary epithelial ovarian cancer. METHODS: A review of 63 patients previously diagnosed as primary epithelial ovarian cancer after initial operation and histology at Pusan National University Hospital from Jul. 1993 to Jun, 1997 was performed. Patients were received the combination chemotherapy including cisplatin 100mg/m2/day and cyclophosphamide 750mg/m2/day, repeated 6 cycles every 4 weeks. The mean age was 48 years old, and previous surgical procedures were total abdominal hysterectomy and bilateral salpingo-oophorectomy with omentectomy. The patients were classified into FIGO stage and pathologic results. RESULTS: The clinical response rate was 100% in the FIGO stage Ic patients with PC combination chemotherapy, 100% in stage II, 53.5% in stage III, and 25% in stage IV. The overall response rate was 69.8%. The 3-year survival rate according to the treatment groups was 93.3% in stage Ic group, 60% in stage II, 50% in stage III and 0% in stage IV. The mean survival duration was 34.6 months. Hematologic toxicities in cisplatin-cyclophosphamide chemotherapy were neutropenia and anemia. Nausea and vomiting were the most common side effects and occurred in 96.8%. Most of the toxicities were grade 1 and 2. CONCLUSION: The combination chemotherapy with cisplatin-cyclophosphamide is relatively safe and effective method in the treatment of primary epithelial ovarian cancer.

In general. femoral neck fracture in young adult presents poor prognosis due to the high velocity injury, high angle shear fracture, and poor candidate for arthroplasty. In addition to the relative rarity of the injury, the high incidence of aseptic necrosis and nonunion have been reported in the management of these fractures. 25 cases of femoral neck fracture in young adult were treated with multiple pinning and analyzed at Sung-Ae general hospital from 1987 to 1994 after 28 months follow up in average with review of charts, X-ray and clinical result. There were 18 male and 7 female, 5 cases of them had significant polytrauma to other organs or skeletal system, authors tried to treat them as soon as possible to decrease the interval time between fracture and fixation (the average time was 39.7 hours.) Union occurred in all of Garden stage I (4 cases) and II (4 cases), but in Garden stage III (7 among 8 cases) and IV (7 among 9 cases) the union rate was lower. Average union time was 16.5 weeks. The incidence of complications (12%, 3 among 25 cases) was higher in displaced fractures group (Garden stage III, IV) and also in poorly reduced group of Garden’s alignment index. In conclusion, the prognosis of femoral neck fractures in young adult was related with mainly initial reduction and rigid fixation than the initial injury.

PURPOSE: To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluated in the healthy population. MATERIALS AND METHODS: Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricualr valve areas. RESULTS: Transient signal void was observed within the atrium near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called "physiologic atrioventricular valvular insufficiency". Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects didnot show any evidences of physiologic insufficiency. This physiologic condition does not extend more than lcm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. CONCLUSION: Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpfal in the study of the normal cardiac physiology.

Protothecosis is a rare cutaneous soft tissue infection caused by the genus prototheca, most commonly Prototheca wickerhatmii. An 80-year-old woman has had a painful or tender, non-healing, eczematous plaque on the extensor surface of the left forearm for 4 years. A biopsy specimen revealed the characteristic thick-walled morulalike sporangia in the dermis. P. wickerha mili was isolated in the culture and the biochemical studies. Electron microscopic examination showed the thick-walled spores containing dark dense bodies and amyloplasts. Oral itraconazole therapy for 4 weeks resulted-in a marked improvement of the skin lesion.

BACKGROUND: Assessment of programmed cell death-ligand 1 (PD-L1) immunohistochemical staining is used for treatment decisions in non-small cell lung cancer (NSCLC) regarding use of PD-L1/programmed cell death protein 1 (PD-1) immunotherapy. The reliability of the PD-L1 22C3 pharmDx assay is critical in guiding clinical practice. The Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists investigated the interobserver reproducibility of PD-L1 staining with 22C3 pharmDx in NSCLC samples.METHODS: Twenty-seven pathologists individually assessed the tumor proportion score (TPS) for 107 NSCLC samples. Each case was divided into three levels based on TPS: <1%, 1%–49%, and ≥50%.RESULTS: The intraclass correlation coefficient for TPS was 0.902±0.058. Weighted κ coefficient for 3-step assessment was 0.748±0.093. The κ coefficients for 1% and 50% cut-offs were 0.633 and 0.834, respectively. There was a significant association between interobserver reproducibility and experience (formal PD-L1 training, more experience for PD-L1 assessment, and longer practice duration on surgical pathology), histologic subtype, and specimen type.CONCLUSIONS: Our results indicate that PD-L1 immunohistochemical staining provides a reproducible basis for decisions on anti–PD-1 therapy in NSCLC.
