Hamartoma of the bladder is quite a rare entity which is composed of a disorderly admixture of mature cellular elements normally present in the urinary bladder. There is a great controversy regarding the pathogenesis of this lesion. Whether it is a true hamartomatous lesion or metaplastic lesion developed secondary to the inflammatory process. Similar or identical lesions has often been given by other names such as florid examples of cystitis glandularis. We prefer to cell florid examples of cystitis glandularis rather than hamartoma when it was occurred in an old age higher then 50th decade. Here we report a case of hamartoma of the urinary bladder in 44 years old man. Cystoscopic examination revealed a papillary polypoid mass which was attached to the fundus of bladder by long stalk. The mass measured 1.5 cm in greatest diameter. It was composed of epithelial nests resembling von Brunn's nest, cystitis glandularis or cystitis cystica dispersed in a stroma rich in smooth muscle and fibrous tissue.

This study was carried out to investigate the intricate mechanisms of intraalveolar fibrosis, leading to the alveolar structural remodeling, of rat lungs treated with paraquat. Sixty-three male Sprague-Dawley rats, maintained on a stock diet, weighing 200.0 gm, average, were divided into 4 experimental groups. Group 1. Control group (10 rats). Intraperitoneal injections of 2-4 ml normal saline only. Group 2(13 rats). 10, 20, 25, 30 and 40 mg per kg of body weight was administered intraperitoneally. Animals were sacificed 5 hours. 1 and 3 days after paraquat treatment. Group 3(16 rats). 20, 25, 30 and 40 mg per kg of body weight was administered to the animal, and animals died 2-5 days after paraquat administration. Group 4(24 rats). The same amount of paraquat was administered to the animal as in the group 2. Animals were sacrificed 1, 2, 6, 8 and 10 weeks after paraquat treatment. Sacrificed animal lung was examined by gross, light-microscopic, immunohistochemical, ultrastructural observation, along with cellular and chemical analyses of bronchoalveolar lavage fluid. The results were as follows: Grossly, 6 rats of chronic stage (1-10 weeks survival) developed multiple wedge-shaped scars on both lungs. These scars were situated mainly along the bronchial trees, blood vessels and subpleural regions. Light microscopically, the salient features found of the chronic stage lungs were intraalveolar fibrosis. Intraluminal buds or polypoid masses projecting into the alveolar lumen and ducts. Elsewhere, loose connective tissue masses were found to fuse together to alveolar wall, obliterating the alveolar spaces with resultant severe alveolar structural remodeling. Immunohistochemically, fibronectin was found in the center of intraalveolar buds and polypoid mass, projecting into the alveolar lumen, and in the adjacent proliferating alveolar macrophages. An attempt to measure the amount of fibronectin in the bronchoalveolar lavage fluid failed. Electron microscopically, the chronic stage lung revealed marked proliferation of both alveolar macrophages and fibroblasts in the alveolar spaces, the latter containing actin-like microfilaments and collagen fibers arranged in bundles and spirals. In areas, myofibroblasts and smooth muscle cells also present. Cellular analysis of the bronchoalveolar lavage fluid in chronic stage lungs revealed no significant findings. It can be concluded, therefore: That intraalveolar fibrosis of the paraquat-treated lungs of the rat is probably mediated by intraalveolar migrations of the interstitial cells, the main task force being the connective tissue cells, passing through the defects created in the epithelial lining surface to its basement membrane, which were inflicted upon the alveolar wall by paraquat toxicity. Fibronectin, released by activated alveolar macrophages, may be responsible for the migrations of fibroblasts and myofibroblasts into the alveolar spaces to form the intraalveolar fibrosis with subsequent alveolar structural remodeling,

The frozen section technique is a means of intraoperative pathological diagnosis, and a procedure of great value to the surgeon. This method should be accurate, rapid and reliable. This method serves useful purposes, such as determining the presence of tumor, its type (especially whether it is benign or malignant), the adequacy of a biopsy of a suspected lesion, and the conditions of the surgical margins. But, it bears many disadvantages, the most of which is the danger of incorrect diagnosis. We studied the indications, the limitations, and the accuracy of the frozen section method and the materials studies was total of frozen section diagnosis of 809 cases was 98.1% with 0.5% of false negative, 0% of false positive 0.5% of incorrect histological diagnosis or grading errors, and 0.9% of deferred cases. The tissues submitted were lymph node, gastrointestinal tract, skin subcutaneous tissues in decreasing oder of frequency. The false positive case is not present, while the false negative cases were 4.

PURPOSE: The purpose of this study was to construct a structural equational model to explain and predict burnout in family caregivers of patients with cancer. The study was based on the Stress-Appraisal-Coping Model of Lazarus and Folkman (1984) and Family Stress Theory (Hill, 1958). METHODS: Data were collected from July 10 to September 30, 2012 through direct interviews and a self-report questionnaire survey. Participants in this study were 206 family caregivers providing care for patients with cancer in In-patient or Out-patient departments of three different general hospitals located in Busan. Measured variables were exogenous variables (social support and perceived health status) and endogenous variables (perceived stress, hope and burnout). RESULTS: Goodness of fit in the hypothetical model was chi2=174.07, TLI=.95, CFI=.97, RMSEA=.08. Perceived health status, perceived stress, and hope showed statistically significant direct effects on burnout of family caregivers. Social support affected burnout of family caregivers indirectly. These variables explained 68.5% of total variance in burnout. CONCLUSION: The results from this study suggest that perceived stress, perceived health status, and hope should be considered as major influential factors when developing nursing interventions to control burnout of family caregivers (of patients with cancer).

To examine the usefulness of cardiac MRI in assessing patients (pt) with congenital heart diseases(CHD), informations obtained from MRI and echocardiogrphy (echo) were compared in 91 consecutive pt with CHD and was correlated with findigs at cardiac catheterization (53pt) and at surgery (71pt). Pt were studied with 1.5 Tesla MRI unit and multiplanar images of the heart and great vessels were obtained using ECG-gated multislice spin-echo technique. Age ranged from newborn to 22 years. We obtained the following results. MRI was vary useful in providing important diagnostic informations in 19pt, provided informations which was not crucial to the clinical decision in 28pt, and did not provide additional informations in 44pt. MRI was very useful in assessing complex lesions, particularly in identifying atrial situs, rudimentary ventricular chamber, criss-cross atrioventricular connection, total anomalous pulmonary venous connection, anatomy of ventricular septal defect in double outlet right ventricle, anomalous ventricular muscles, aortopulmonary collateral artery and distal pulmonary artery anatomy. En face view of the ventricular septum was very useful in clearly outlining the ventricular septal defect. MRI gave false information in 17pt. Diagnostic accuracy of MRI was poor for coarctation of the aorta in neonates and small infants, patent ductus arteriosus and pulmonary stenosis. Cardiac MRI is recommended for preoperative planning in selected pt with CHD, particularly with complex lesions.

BACKGROUND: Thyroid status in uremia is still inconclusive due to the complexicity of the system. No single pathogenetic event may explain the thyroid function abnormalities in end stage renal disease (ESRD). Defects at all levels of the hypothalamic-pituitary-thyroid axis have been identified. Regarding the thyroid dysfunction in ESRD it is well recognized that the TSH response to TRH is blunted and serum concentrations of thyroid hormones are decreased in patients with ESRD. Whether or not on maintenance hemodialysis. Restoration of renal function with renal transplantation resulted in normalization of all parameters of thyroid function with exception of blunted TSH response to TRH. We evaluated the long-term changes of the thyroid function in 10 patients to know whether the thyroid function and the hypothalamo-pituitary axis were improved with the recovery of the renal function under maintenance low-dosage steroid administration after renal transplantation. METHODS: These tests were performed during the morning in the fasting state in 10 ESRD patients before, 1 month and 6 years after renal transplantation (RT). Thyroid function tests. Serum T3, T4 were measured by RIA kit and serum TSH was measured by IRMA kit. TRH stimulation test. Serum blood samples were obtained 0, 30, 60, 90, 120 min after TRH (400microgram) administration. Statistical analysis. All grouped data were expressed as mean+/-SD. Student t-test was used to assess the statistical difference between any two means. RESULTS: 1) The mean basal level of serum T3 was reduced in ESRD patients (53.6+/-33.2ng/dL) and increased to the low normal level 1 month after RT (87.8+/-25.4ng/dL), improved to the normal level 6 years after RT (116.3+/-28.8ng/dL). 2) The mean basal level of T4 was within normal range before RT (5.9+/-1.1microgram/dL), after 1 month (6.2+/-1.2microgram/dL) and after 6 years (6.5+/-1.4microgram/dL) of RT. 3) The mean basal level of TSH was within normal range before RT (2.0+/-1.2microU/mL), after 1 month (1.1+/-0.7microU/mL), and after 6 years (0.7+/-0.5microU/mL) of RT. Rut the mean TSH level of 6 years of RT was significantly decreased within the normal range. 4) In ESRD the TSH response to TRH was blunted, had a diminished peak and delayed fall before RT. After 1 month of RT, the TSH response to TRH was persistently blunted, however showed more rapid fall of TSH. After 6 years of RT, the TSH response to TRH normalized, but the absolute level of TSH and the peak level of TSH to TRH were less than before and after 1 month of RT. CONCLUSIONS: The abnormalities of thyroid hormones in uremic patients were improved partially after 1 month of RT and almost completely after 6 years of RT. But the level of T3H and the peak level of TSH to TRH were low within normal range, these results may be a direct consequence of low-dosage and long-term glucorcorticoid administration.

PURPOSE: The purpose of the study was to explore and describe hospice palliative nurses' experience of caring for terminal cancer patients. METHODS: Eleven hospice palliative nurses participated in the study. Data were collected through individual in-depth unstructured interviews with participants from November, 2012 to October, 2013. Theoretical sampling was used to the point of theoretical saturation. Data were analyzed using Corbin and Strauss' 'Grounded Theory Method.' RESULTS: From open coding, 25 sub-categories and 12 categories were identified. Analysis revealed that the core category was 'becoming stepping-stones between life and death enduring burdens', consisting of three phases: the phase of withdrawal, the phase of exertion, and the phase of maturity. Through this process, participants utilized various action/interactional strategies such as 'maintaining a distance', 'sharing intimate daily life', 'being a mediator for a peaceful death', 'grieving and remembering'. The consequences of these strategies were a transcendental perspective towards life and ambivalent feelings toward hospice nursing. CONCLUSION: In-depth understanding of the hospice palliative nurses' experience of caring for terminal cancer patients will guide nurse managers and policy makers to promote effective nursing strategies to better support hospice palliative nurses.
