The majority of ptients with ischemic heart disease such as angina pectoris and myocardial infarction have coronary atherosclerosis as a underlying cause. However, in unusual conditions such as variant angina, aortic valvular heart disease, hypertrophic cardiomyopathy, vasculitis, hypercoagulable states, coronary atherosclerosis is not the cause. Polycythemia vesa is a myeloproliferative disease characterized by infrequent thromboembolic complications such as ischemic heart disease. We report a case of polycythemia vera presenting with angina pectoris without coronary artery stenosis with the review of the literature.

BACKGROUND: Viral myocarditis is considered as a cause of dilated cardiomyopathy. At present, two pathogenic mechanisms may be involved in the pathogenesis of viral myocarditis and subsequent cardiomyopathy. First, the virus infection of myocyte may directly lead to either cell death or persistent metabolic dysfunction. Second, virus-induced immune or autoimmune mechanism may play a role. METHODS: To test the therapeutic efficacy of immunosuppression with cyclophophamide(CYP) on coxsackievirus B3(CB3) myocarditis, 10-14 week-old Balb/c mice were inoculated with 4000 plaque-forming units of CB3. In experiment 1, CYP (100mg/kg/day subcutaneous injection, s.c) was administrated daily on days 1-7(group 2, n=16). In experiment 2, CYP 30mg/kg/day s.c(group 3, n=32) or CYP 100mg/kg/day s.c(group 4, n=32) were administrated on days 8-14. The animals of infected controls(group 1, n=26) and group 2, 3, 4 were dissected at days 4, 7, 15, 22 and spleen, heart, thymus and body weights were measured. RESULTS: In experiment 1. survival rate in group 2 on day 7, 15 were low compared with group 1(85%, 0% vs 100%, p<0.05). and myocardial virus titers in group 2 on day 4 was 50 times, and on day 7, 1000 times higher compared with group 1, Histologically, on day 7, focal cellular infiltrations were prominent findings in group 1, but diffuse myocardial necrosis without cellular infiltration were observed in group 2. In experiment 2, survival rate, cardiac histopathology myocardial virus titer and serum neutralizing antibody titers did not differ among groups 1, 3 and 4. In experiment 1 and 2, the spleen-to-body-weight and thymus-to-body-weight ratios were significantly lower in CYP treated groups than those in controls and marked cellular depletions in spleens and thymus were observed in CYP treated groups. CONCLUSIONS: As the results of above, it can be concluded that the immunosuppression during viremic phase of murine viral myocarditis aggravated the myocardial necrosis, and during aviremic phase, the administration of CYP didnot affect the process of viral myocarditis. Thus, direct viral mechanisms in the production of cardiomyocyte injury in CB3-infected mice appear to bo more important than cell mediated immune mechanism. To understand relevant pathogenic mechanisms of clinical myocarditis and dilated cardiomyopathy resulting from viral infection, the experimental study expanding into nonmurine animals and into various models using other infectious agents may be required.

PURPOSE: The study was conducted to determine if there is a corneal astigmatic changes after upper eyelid surgery by using corneal topography and if these changes are the reason why some patients note a decrease in visual acuity. METHODS: Twenty four eyes of 12 patients with dermatochalasis who had undergone upper eyelid blepharoplasty, and 24 eyes of 12 patients who had undergone aesthetic double fold formation were included. We performed corneal topography during the postoperative 3 months and also evaluated the corneal refractive index change on thirteen points of the central cornea, which were located in the center of the corneal apex and apart from it by 1.5, 2.5, 3.5 mm along each axis corresponding to the 0 degrees, 90 degrees, 180 degrees, 270 degrees respectively. RESULTS: Corneal topography demonstrated increase in with-the-rule astigmatism by 38, 33, and 12% for dermatochalasis patients at 1week, 1month, and 3months after surgery, and by 25%, 17%, and 13% for double fold patients. However the increase in with-the-rule astigmatism seemed to be temporary, showing gradual regression. The refractive index change of thirteen points of central cornea was not significant except a few eyes with astigmatic changes greater than 1D until 1 month after surgery. There was alsoincreased astigmatism after surgery in vector-corrected analysis. CONCLUSIONS: There was a tendency of increase in with-the-rule astigmatism and those changes were temporary and regressed gradually. No patient showed significant refractive index change on the 13 points of central cornea but some showed changes greater than 1 D in the early postoperative period, causing visually significant astigmatic changes temporarily.

OBJECTIVE: The aim of this study is to assess the effectiveness of oral progestin treatment in women diagnosed with complex atypical hyperplasia (CAH) or grade 1 endometrial cancer (G1EC), who desire to preserve their fertility, as alternative treatment to a hysterectomy. METHODS: We reviewed the medical records of women younger than 45 years old that had been diagnosed with CAH or G1EC, who expressed a desire to preserve their fertility using alternative treatment at our institution. Women without evidence of myometrial invasion on pelvic magnetic resonance imaging scans were included. The study period was between 2004 and 2014. Endometrial biopsies were taken at follow-up appointments. RESULTS: We identified 31 young women with CAH or G1EC. The median age was 33 years old (range, 20 to 41), and the median period of time undertaking the treatment was 5 months (range, 1 to 12). Twenty-three patients (74.2%) achieved complete remission (CR; median time to CR was 3 months; range, 1 to 22), 16 patients (88.9%) with CAH and 7 (53.8%) with G1EC achieved CR. 6 patients (26.1%) who had achieved CR, had recurrence of the disease (median time from CR to recurrence was 12.5 months; range, 4 to 18). Eight patients (25.8%) finally underwent a hysterectomy. CONCLUSION: Oral progestin therapy is an alternative treatment for women with CAH or G1EC who desire fertility preservation. However, more prospective studies are needed for standard progestin regimen. Also, there still remains a risk of disease progression and recurrence. Therefore, close follow-up is important during treatment and after CR. In addition, a hysterectomy is recommended as a definitive treatment after completion of childbearing.

Subacute thyroiditis is a self-limiting inflammation of the thyroid, presenting with painful thyroid swelling, thyrotoxicosis and low radioactive iodine uptake. The characteristic US findings for this disease are focal ill-defined hypoechoic areas in one lobe or diffuse hypoechoic areas in both lobes. Thyroid carcinomas should be included in the differential diagnosis for a lesion with focal hypoechoic areas and have been rarely reported to coexist with subacute thyroiditis. Takayasu's arteritis is an autoimmune disease that affects the aorta and its branches as well as pulmonary arteries. Subacute thyroiditis associated with Takayasu's arteritis is extremely rare, with only three cases being reported. We report here on the first case with the simultaneous diagnosis of subacute thyroiditis, papillary thyroid carcinoma and Takayasu's arteritis.

The Nuss procedure has good cosmetic effects, but it could be cause of bleeding and organ injury during dissection of the anterior mediastinum. We have made an effort to overcome the defects of the traditional method through the anterior mediastinum, thus we developed a transilluminated introducer that made it safer and simpler to operate within a 1 cm incision only. A total of 67 patients underwent the Nuss procedure using the transilluminated introducer. Thirty-six patients underwent the procedure with the transilluminated introducer only (age<14 years). Thirty-one patients had an additional thoracoscopy (age> or =14 years). There were no major complications, such as massive bleeding or organ injury in the thoracic cavity during or after the Nuss procedure. Our findings demonstrated that the anterior mediastium could be dissected simply and safely by the use of a transilluminated introducer during the Nuss procedure without fatal major complications, such as bleeding and organ injury.

PURPOSE: Fine needle aspiration cytology (FNAC) has become a standard diagnostic tool for thyroid nodules. The purpose of this study is to analyze the correlation between FNAC and the final histology to improve the diagnostic value. METHODS: We collected 792 patients who had undergone thyroidectomy, and we selected 549 patients who had undergone preoperative FNAC. The FNAC results were classified as non-diagnostic, malignancy, indeterminate and benign. The final pathologic reports were classified into two categories: malignant or benign. The individual histology was also identified. We retrospectively analyzed the pathologic result, the sensitivity, the specificity and the predictive value of the FNAC. RESULTS: Among 549 patients, their FNACs showed 47 non diagnostic results, 189 malignancies,136 indeterminate results and 177 benign results. The false positive rate was 1.1% and the false negative rate was 12.9%. The final pathology reports were 262 malignancies and 287 benign lesions. There were 42 (30.9%) malignancies among the 136 indeterminate cases. Adenomatous hyperplasia was the most common benign lesion and papillary carcinoma (containing micropapillary carcinoma) was the most common benign lesion. CONCLUSION: FNAC is an easy and safe diagnostic tool, but it still has many limitations. It is necessary to reduce the number of non diagnostic results. Technical advances, classification of the advanced categories of cytology and other staining methods can provide more specific results, and this can reduce the rate of performing unnecessary surgery.

Congenital laryngeal cleft is a rare anomaly, which can cause serious problems of airway and repeated aspiration pneumonia. It is due m failure of fusion of the posterior cricoid cartilage lamina. Dysphagia with aspiration of food is commonly seen w1h resultant bouts of pneumonia. Detection of an unsuspected minor cleft may be difficult, but the pediatrician should suspect the possibility of deft from the clinical features. This paper includes. a detailed case report of one patient with congenital laryngeal cleft and the review of literatures.

Primary adenocarcinoma of the duodenum is a rare disease, representing 0.35% of all gastrointestinal neoplasm and 0.042% of all malignant neoplasm. Since Ham-burger described the first duodenal caricinoma in 1746, the incidence has shown an increasing tendency. Compared with upper gastrointestinal contrast studies, the gastroduodenoscopy has gained an increasing popularity as an invesitigative tool in recent years. But the diagnosis is usually made at a very late stage because the symptoms are often non-specific, which contributes to delayed diagonsiss and poorer prognosis. We have experienced two cases of the primary carcinoma of the duodenal bulb and one case of carcinoma of the second portion, which were diagnosed by biopsy with gastrofiberoscopic endoscopy and operative finding. So we report three csses with a brief review of literature.
