Abstract Gastrointestinal stromal tumor (GIST) is a recently described mesenchymal tumor that can develop in any portion of the gastrointestinal tract. The occurrence of a GIST in the urinary tract is rare, but GIST can present as tumor of the urinary tract or invade the urinary tract. This is the first reported case of GIST in the ileal neobladder, which presented as a submucosal tumor. The patient underwent an open exploration and partial resection of the neobladder pouch. 相似文献

AIM: To evaluate the cause of elevated prostate-specific antigen (PSA) in patients with transrectal needle biopsy negative for prostate cancer. METHODS: Serum PSA concentration, prostate volume, and pathologic findings were examined in 223 patients with negative biopsy for prostate cancer. The degree of prostate inflammation was determined by the extent and degree of inflammation shown by biopsy specimens and is expressed as an inflammation score (range: 0-36). RESULTS: A significant correlation was found between PSA concentration and prostate total volume (P=0.0001). Prostate chronic inflammation showed no correlation with PSA concentration (P=0.485, F=0.488). After allocating patients to normal PSA (4 ng/mL) groups, we found that serum PSA concentrations in both groups were predominantly affected by prostate total volume. CONCLUSIONS: An increase in prostate volume appears to be the major contributor to a high serum PSA concentration in patients with negative biopsy for prostate cancer. However, in contrast to previous reports, there was no correlation between the degree of prostate chronic inflammation and serum PSA concentrations. 相似文献

Different doses of hepatitis B virus vaccine—prepared by Korea Green Cross Corporation, were given to healthy infants born to HBsAg-negative mothers at birth, 1 and 6 months of age. A dose of 2 μg was administered intradermally in Group A and, in the three other groups, the vaccine was given intramuscularly (i.m.). An adequate follow-up observation was possible for 9 months after birth in 22, 25, 23 and 21 infants in Groups A, B, C and D, respecvely.
Group C (5 μg, i.m.) produced seroconversion most rapidly, showing the highest rate (96%) at 9 months of age. The lowest seroconversion rate (5%) was found at the age of 1 month in Group A subjects, but the rate increased to 91% after a booster dose was given at 6 months of age.
While it can be concluded that a 5 μg i.m. dose of vaccine at 0, 1 and 6 months of age is optimum for the immunization of infants in efficacy and economy, a 2 μg intradermal dose can also be considered as an immunogenic and economical regimen, though the immune response is slower and a special technique is required for immunization. 相似文献

The spectrum of angiographic finding in 20 patients with transitional cell carcinomas of the kidney is described. In 15 of 20 patients (75%), prospective diagnosis of transitional cell carcinomas were made because of a combination of the angiographic findings; tumour vessels, tumour stain, prominent pelviureteric arteries and arterial encasement. In 4 patients with negative angiograms the lesions were relatively small in size and were situated within the renal parenchyma, primarily involving the calyces. The use of pharmacoangiographic agents such as epine-phrine and priscoline improved the angiographic visualization of transitional cell carcinomas of the kidney. For the past several years angiography has had a central role in the evaluation of patients with hematuria and renal masses1. 5,6,7,8. Although the use of diagnostic ultrasound and renal puncture have eliminated angiography from the diagnosis of renal cysts, most renal masses which are solid or which have equivocal findings at ultrasound still undergo angiography. At the same time, the decreasing use of retrograde urography has resulted in more frequent angiography in patients with unilateral nonfunctioning kidneys. Transitional cell carcinomas of the renal pelvis are an important cause of both hematuria and non-functioning kidneys. We have therefore reviewed our material to reassess the angiographic abnormalities caused by the transitional cell carcinomas and the overall accuracy of the angiography in the diagnosis of these lesions. 相似文献

Koo JS, Shin E, Hong SW. Immunohistochemical characteristics of diffuse sclerosing variant of papillary carcinoma: comparison with conventional papillary carcinoma. APMIS 2010; 118: 744–52. Diffuse sclerosing variant of papillary carcinoma (DSVPC) is a rare variant of papillary thyroid carcinoma (PTC). It shows different clinicopathologic features to the conventional PTC, but the immunohistochemical characteristics of DSVPC are yet to be more clearly defined. The purpose of this study was to investigate the immunohistochemical features of DSVPC, which are different from those of PTC. Tissue microarray was constructed from the paraffin‐embedded tissue of 49 DSVPC and 50 conventional PTC samples. Immunohistochemical stains for p63, p53, galectin‐3, cytokeratin 19, β‐catenin, Bcl‐2, EMA, E‐cadherin, CD15, and CD56 were performed on each tissue microarray. Immunohistochemical stain for p63 was negative in all conventional PTCs, but 14 (28.6%) cases of DSVPC showed p63 expression (p = 0.000). p53 was expressed in 38 (76.0%) cases of conventional PTC and 21 (42.9%) cases of DSVPC (p = 0.001). Galectin‐3 was expressed in all 50 cases of conventional PTC, but eight (16.3%) cases of DSVPC did not express galectin‐3 (p = 0.003). EMA was expressed more in DSVPC (40.8%) than in conventional PTC (20.0%, p = 0.024). In univariate analyses, Bcl‐2 positivity (p = 0.016) and EMA negativity (p = 0.036) in DSVPC were associated with shorter time interval to tumor recurrence, but there was no significance for the two in multivariate analyses. DSVPC, a rare variant of PTC, has different immunohistochemical features from the conventional PTC, showing higher expression rate of p63 and lower expression rate of p53. It also shows galectin‐3 negativity and EMA positivity. 相似文献

Fourteen patients who received a bone marrow transplant (BMT) as treatment for leukaemia were included in a prospective study of the histological changes in the skin. The aim of this study was to improve the early diagnosis of graft-versus-host disease (GVHD). It was found that the clinically 'normal' pre-transplant skin was in some cases histologically abnormal on H & E examination in patients who were on regular maintenance cytotoxic chemotherapy. These changes were similar to some of the features of GVHD. Immunocytochemistry, although not specific, was found to be helpful in the diagnosis of some cases of GVHD. Suggestive features included a reduction in the numbers of Langerhans cells, an increase in the number of suppressor (OKT8+) cells in the dermal infiltrate and the presence of Ia positivity of the keratinocytes in the epidermis. 相似文献

AIM: This study was conducted to investigate the effect of DA-8159, a new phosphodiesterase type-5 (PDE5) inhibitor, on electrostimulation-induced penile erection in rats. METHODS: Intracavernous pressure (ICP) and arterial blood pressure (BP) were simultaneously recorded through electric pelvic-ganglion stimulation (2-10 Hz) after the oral administration of DA-8159 (3 or 10 mg/kg) in normal and streptozotocin-induced diabetic rats. Statistical analysis was performed on the maximal intracavernous pressure (ICP), detumescence time, maximal intracavernous pressure/blood pressure (ICP/BP) ratio, and the area under the curve (AUC) of the ICP/BP ratio. RESULTS: In normal and diabetic rats, electrical stimulation of the pelvic ganglion induced a frequency- and dose-dependent increase in the intracavernous pressure. The ICP/BP ratio and the corresponding AUC values were also significantly and dose-dependently increased after DA-8159 administration. In addition, the detumescence time significantly increased after DA-8159 administration compared to that of the controls. CONCLUSIONS: These results show that the DA-8159 significantly increased the intracavernous pressure response and prolonged the decay period induced by electrical stimulation of the pelvic ganglion, and suggest that DA-8159 might be a potential therapeutic agent for the treatment of erectile dysfunction. 相似文献

We report two cases showing black discoloration of the thumb nail which were histologically found to be acral lentiginous melanoma (ALM) in situ. A pigmented subungual lesion is more frequently malignant than benign and it is generally believed that diagnosis of subungual melanoma during the radial-growth phase is very difficult. Our cases are particularly interesting because atypical melanocytic hyperplasia was confined to the epidermis despite the lesion being present for a long time. 相似文献

Percutaneous Retrieval of Dislodged Left Atrial Appendage Occlusion Devices through the Transseptal Approach 下载免费PDF全文
SANG YEUB LEE M.D. JIN‐SEOK KIM M.D. SEUNG YONG SHIN M.D. HONG EUY LIM M.D. Ph.D. 《Pacing and clinical electrophysiology : PACE》2016,39(8):903-906
Percutaneous left atrial appendage (LAA) occlusion is a promising treatment option in patients with atrial fibrillation who have a high risk of embolic stroke and are not eligible for chronic oral anticoagulation therapy. This procedure, however, can induce several complications. Device embolization can result in a serious situation, requiring immediate and safe device removal. We report two cases in which dislodged LAA occlusion devices were flitting in the left atrium or entrapped in the mitral valve leaflets and were successfully retrieved through a transseptal approach without complications. 相似文献
