The aim of the present study is to demonstrate the usefulness of intraoperative fine needle aspiration (FNA) of pancreatic lesions in 30 patients. A conclusive diagnosis was done in 27 patients and the diagnoses of three patients were deferred. No complications followed the procedure. Based on histologic findings of the resected specimens in 20 cases and of cell blocks in 10 cases, the final diagnoses were adenocarcinoma in 19 cases, chronic pancreatitis in nine cases and tuberculosis in two cases. The sensitivity, specificity and diagnostic accuracy were 95%, 100% and 96% resepectively and there were no false positives. The smear of aspirate was stained with toluidine blue and examined by light microscope. The presence of there-dimensional clusters of disoriented cells and the increased nuclear/cytoplasmic ratio with large prominent nucleoli were the most helpful criteria for a diagnosis of malignancy in the pancreas. The intraoperative FNA of pancreatic lesions was considered as a simple, safe, and highly specific and sensitive tool in differentiating benign from malignant lesions. The intraoperative FNA can be recommended as the first tool of choice of intraoperative diagnostic procedure in lesions of the pancreas.

PURPOSE:This study was performed to investigate the status of cardiac structure and function and to assess their alterations after growth hormone(GH) treatment in children with growth hormone deficiency(GHD). METHODS:Interventricular septal thickness and left ventriclular posterior wall thickness, ejection fraction(EF), fractional shortening(FS), systolic time interval(STI) of left ventricle were measured by two-dimensional and M-mode echocardiography in sixteen children with GHD and age, sex matched sixteen children with GH normal short stature as control. The measure were done before GH treatment and at 6 and 12 months of GH treatment, respectively. RESULTS: 1)Left ventricular posterior wall thickness in GHD group was significantly thinner than that of control group(P<0.05). 2)Interventricular septal thickness and left ventricular posterior wall thickness were increased with GH treatment from 10.4+/-1.7mm, 8.1+/-1.8mm before GH treatment to 11.0+/-0.9mm, 8.7+/-0.7mm and 11.2+/-1.7mm, 9.7+/-1.8mm at 6 and 12 months of GH treatment, respectively. The increment of left ventricular posterior wall thickness after 12 months GH treatment revealed statistic significance(P<0.05). 3)There was no significant alterations of EF, FS, STI of left ventricle after GH treatment at 6 months and 12 months, respectively. CONCLUSION: Left ventricular posterior wall thickness in GHD group was significantly thin compared to that of control group(P<0.05). GH treatment in GHD children for 12 months, resulted statistically significant increase(P<0.05) in posterior wall thickness. There is no evidence of hypertrophic cardiomyopathy after GH treatment. But we could not exclude the possibility of these alterations were induced by an increased overall body size and body surface area after GH treatment. To clarify the exact alterations of cardiac structures and function in children with GHD after GH treatment, long term follow-up studies should be necessary.

BACKGROUND: The reproducibility in grading a cervical intraepithelial neoplasia (CIN) are not perfect. The aim of this study was to assess the value of the immunohistochemical expression of p63 and the other biomarkers for grading a CIN (dysplasia and in situ carcinoma), and diagnosing invasive carcinomas. METHODS: Sixty six cervical specimens were immunostained with the monoclonal antibodies against p63, Ki-67, p27Kip1, and p53 to determine the localization. RESULTS: The p63 positive cells are well linked with squamous cell maturation and the degree of dysplasia. In mild dysplasia, the p63 positive cells were localized to the basal and parabasal cells, which gradually extended into the middle and upper layers in moderate and severe dysplasia. p63 expression was strong in immature squamous epithelium and invasive squamous cells, but was constantly absent in an adenocarcinoma. The Ki-67 positive cells were scattered from the parabasal cells to the superficial cells in accordance with the degree of dysplasia. p27Kip1 expression was noted in the intermediate cells in the normal cervix. In CIN, the p27Kip1 positive nuclei tended to extend to the basal cells, but it showed no diagnostic consistency in an invasive carcinoma. p53 expression was also variable. CONCLUSION: p63 is a useful diagnostic adjunct for grading CIN as well as for detecting microinvasion and squamous differentiation in invasive carcinoma. However, immunohistochemical expressions for the p27Kip1 and p53 have no correlation with the grade of CIN and squamous cell carcinoma.

To determine the prevalence and risk factors of hypertension we performed cross-sectional study in a rural area. We measured BP and body mass index(BMI), and interviewed adult residents over 30-year-old age. 337 males and 357 females participated the survey. BP was checked twice and the mean was used to determine age and sex specific mean BP and prevalence of hypertension. Prevalence of definite hypertension(BP>or=160/95 or on medication) was 14. 0% in males and 17. 7% in females. Risk factor for hypertension was analysed by multiple logistic regression; age (10years: OR=l. 7) and BMI(1 BMI unit: OR=l. 2) were positively associated with hypertension but smoking(1 pack year: OR=0.9) was shown to have inverse relationship.

Osteoporosis is one of the major causes of insufficiency fractures, and since plain radiographic findings are either unhelpful or misleading, insufficiency fracture in the sacrum is particularly difficult to diagnosis and to differentiate from other disease processes such as metastasis. We report the MR findings of two cases of insufficiency fracture of the sacrum. These were not demonstrable on conventional radiographs, but bone scintigraphy revealed unilateral sacral alar uptake, suggesting an active sacral lesion. Both T1 and T2-weighted MR images demonstrated fractures of the sacrum as bands of low signal intensity, with areas of surrounding increased signal intensity seen on the latter suggesting marrow edema.

The hyperosinophilic syndrome (HES) commonly involves liver and spleen but only a few literature has reported the imaging features. In this article, we present the imaging features of the liver and spleen in HES patients together with clinical and laboratory features. This study included 5 HES patients with hepatic involvement. Extensive laboratory tests including multiple hematologic, serologic, parasitologic, and immunologic examinations were performed. Imaging studies included CT, ultrasound (US) of upper abdomen and hepatosplenic scintigraphy. All patients were periodically examined by laboratory and imaging studies for 4 to 24 months. The common clinical presentations were weakness, mild fever, and dry cough. All patients revealed leukocytosis with eosinophilia of 40 to 80% and benign eosnophilic hyperplasia of the bone marrow. The percutaneous biopsy of the hepatic focal lesions performed in 2 patients showed numerous benign eosinophilic infiltrates and one of them revealed combined centrilobular necrosis of hepatocytes. All cases revealed hepatomegaly with multiple focal lesions on at least one of CT, US, or scintigraphy. These findings completely disappeared in 2 To 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphy. These findings completelydisappeared in 2 to 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphic studies showed hepatic multifocal lesions with hepatomegaly. Differential diagnoses of these findings should include metastatic disease, lymphoma, leukemia. candidiasis or other opportunistic infections.
