Hemophilia is a sex-linked recessive hereditary bleeding disorder occurring only in the male and transmitted by the female. This disease is characterized by a bleeding tendency due to prolonged coagulation time causing by deficiency of one of three plasma factors, such as anti-hemophilie globulin(A. H. G.), plasma thromboplastin component(P. T. C.) and plasma thromboplastin antecedent (P. T. A.) for first phase of coagulation process. The majority of hemophilia, 74% is due to a deficiency of A. H. G., 15% to a deficiency of P. T. C. and remaining 11% to a deficiency of P. T. A. as outlined in the literature. This case, 18 years old male, is complained of repeated hemorrhagic manifestations, residual deformity with stiffness of the hip and knee joints, and limping following minor trauma has developed since early childhood. Radiologically, the hip and knee joints were involved, showing the findings of typical hemophilic arthropathy. Laboratory finding showed markedly prolonged coagulation time. Diagnosis was confirmed to be plasma thromboplastin antecedent deficiency homophilia.

We report a case of metastatic carcinoma of the skin in 62-year-old male who showed multiple nodules on the anterior chest, scalp, face and left axilla for 2 months duration. He suffered from lower abdominal discomfortness for 6 months. Histopathologic findings revealed atypical cell nests and some tubular or glandular formation in the dermis and subcutaneous fat tissue. Material in the lumen showed diastase resistant and PAS positive, and alcian blue positive at pH 2.4, but negative pH 0.4. So it represented sialomucin. We did not find primary site of malignant tumor. In view of clinical and histopathological findings, it was considered to be originated from the large intestine.

Nitric oxide (NO) production by endothelial nitric oxide synthase (eNOS) plays a protective role in cerebral ischemia by maintaining vascular permeability, whereas NO derived from neuronal and inducible NOS is neurotoxic and can participate in neuronal damage occurring in ischemia. Matrix metalloproteinases (MMPs) are up-regulated by ischemic injury and degrade the basement membrane if brain vessels to promote cell death and tissue injury. We previously reported that agmatine, synthesized from L-arginine by arginine decarboxylase (ADC) which is expressed in endothelial cells, has shown a direct increased eNOS expression and decreased MMPs expression in bEnd3 cells. But, there are few reports about the regulation of eNOS by agmatine in ischemic animal model. In the present study, we examined the expression of eNOS and MMPs by agmatine treatment after transient global ischemia in vivo. Global ischemia was induced with four vessel occlusion (4-VO) and agmatine (100 mg/kg) was administered intraperitoneally at the onset of reperfusion. The animals were euthanized at 6 and 24 hours after global ischemia and prepared for other analysis. Global ischemia led severe neuronal damage in the rat hippocampus and cerebral cortex, but agmatine treatment protected neurons from ischemic injury. Moreover, the level and expression of eNOS was increased by agmatine treatment, whereas inducible NOS (iNOS) and MMP-9 protein expressions were decreased in the brain. These results suggest that agmatine protects microvessels in the brain by activation eNOS as well as reduces extracellular matrix degradation during the early phase of ischemic insult.

PURPOSE: The purpose of this study was to evaluate the pattern and the magnitude of stress distribution in the supporting tissues surrounding three different types of implants(ITI, 3i, and Bicon implant system). MATERIAL AND METHOD: Photoelastic models were made with PL-2 resin(Measurements Group, Raleigh, USA) and three implants of each kind were placed in the mandibular posterior edentulous area distal to the canine . For non-splinted restorations, individual crowns were fabricated on three titanium abutments. For splinted restorations, 3-unit fixed partial dentures were fabricated. Photoelastic stress analyses were carried out to measure the fringe order around the implant supporting structure under simulated loaded conditions(15 lb, 30 lb). CONCLUSION: The results were as follows; 1. Regardless of the implant design, stresses were increased in the apex region of loaded implant when non-splinted restorations were loaded. While relatively even stress distribution occurred with splinted restorations. Splinting was effective in the second implant. 2. Strain around Bicon implant were lower than those of other implants, which confirmed the splinting effect. The higher the load, the more the stress occurred in supporting tissue, which was most obvious in the Bicon system. 3. Stress distribution in the supporting tissue was favorable in the ITI system, while the other side of 3i system tended to concentrate the stress in some parts.

PURPOSE: To examine the effects, complications, and safeties of sclera allograft and amniotic membrane transplantation with fibrin glue as surgical treatment methods for scleromalacia. METHODS: The study included 14 eyes of 14 scleromalacia patients who needed surgical treatment. Among them, seven eyes of seven patients whose scleral defect was small (<6 mm) were operated on using only fibrin glue and no suturing, while seven eyes of seven patients whose defect was large (>6 mm) were operated on using fibrin glue and minimum suturing. Amniotic membrane transplantation was performed at the site of the conjunctival defect. RESULTS: In all of the cases, the results of grafting were successful throughout the follow-up period, which was 14.6+/-4.4 months, on average (ranging from 12 to 27 months). No particular complication was observed during the follow-up period after using fibrin glue. CONCLUSIONS: For scleromalacia patients, sclera allograft and amniotic membrane transplantation were performed using fibrin glue. The grafted sclera survived successfully, allowing this treatment modality to be considered an effective and safe option without complications.

We report a case of eccrine adenocarcinoma in 65-year-old man who showed tender, painful, dark-brown colored, and verrucous surfaced tumor on the left neck for 18 months. Hisopathologic examination revealed large atypical cell masses with a tubular cystic, or adenoid pattern in the demis and it was difficult to differentiate from metastatic adenocarcinoma. Materials in the lumina revealed PAS positive, diastase resistant, alcian blue positive at pH 2.5 but negative at pH 0,4 Electron microscopy revealed that tumor cells contained secretory vacuoloes and microvilli projected into intercellular space. Around the cells, myoepithelial cell was seen. After radiotherapy and chemotherapy, tumor size was reduced transiently but 2 months later, tumor was more spread.

PURPOSE: Combined chemoradiotherapy is standard management for locally advanced non-small cell lung cancer (LA-NSCLC), but standard treatment for elderly patients with LA-NSCLC has not been confirmed yet. We evaluated the feasibility and efficacy of concurrent chemoradiotherapy (CCRT) for elderly patients with LA-NSCLC. MATERIALS AND METHODS: Among patients older than 65 years with LA-NSCLC, 36 patients, who underwent CCRT were retrospectively analyzed. Chemotherapy was administered 3-5 times with 4 weeks interval during radiotherapy. Thoracic radiotherapy was delivered to the primary mass and regional lymph nodes. Total dose of 54-59.4 Gy (median, 59.4 Gy) in daily 1.8 Gy fractions and 5 fractions per week. RESULTS: Regarding the response to treatment, complete response, partial response, and no response were shown in 16.7%, 66.7%, and 13.9%, respectively. The 1- and 2-year overall survival (OS) rates were 58.2% and 31.2%, respectively, and the median survival was 15 months. The 1- and 2-year progression-free survivals (PFS) were 41.2% and 19.5%, respectively, and the median PFS was 10 months. Regarding to the toxicity developed after CCRT, pneumonitis and esophagitis with grade 3 or higher were observed in 13.9% (5 patients) and 11.1% (4 patients), respectively. Treatment-related death was not observed. CONCLUSION: The treatment-related toxicity as esophagitis and pneumonitis were noticeably lower when was compared with the previously reported results, and the survival rate was higher than radiotherapy alone. The results indicate that CCRT is an effective in terms of survival and treatment related toxicity for elderly patients over 65 years old with LA-NSCLC.

We report a successful repair of severe traumatic tricuspid regurgitation by PTFE chordal replacement and ring annuloplasty. A 64-year-old man with multiple trauma was referred to our department because of cardio- megaly on chest roentgenogram. Echocardiography showed moderate amount of pericardial effusion and severe tricuspid regurgitation with rupture of anterior papillary muscle. But he experienced progressive dyspnea, and chest roentgenogram showed progressive cardiomegaly. He underwent operation 4 months after trauma. The nterior papillary muscle was reinserted, and the valve was repaired by PTFE chordal replacements and ring annuloplasty. Postoperatively, the patient's functional status was improved, and there was trivial tricuspid regurgitation on echocardiographic examination.
