We evaluated the predictors of renal scar in children with urinary tract infections (UTIs) having primary vesicoureteral reflux
(VUR). Data of patients who were examined by dimercaptosuccinic acid (DMSA) scintigraphy between 1995 and 2005 were evaluated
retrospectively. Gender, age, reflux grade, presence/development of scarring, breakthrough UTIs, and resolution of reflux,
were recorded. The relation of gender, age and VUR grade to preformed scarring and the relation of gender, age, VUR grade,
presence of preformed scarring, number of breakthrough UTIs and reflux resolution to new scarring were assessed. There were
138 patients [male/female (M/F) 53/85]. Multivariate analysis showed that male gender [odds ratio (OR) 2.5], age ≥ 27 months
in girls (OR 4.2) and grades IV–V reflux (OR 12.4) were independent indicators of renal scarring. On the other hand, only
the presence of previous renal scarring was found to be an independent indicator for the development of new renal scar (OR
13.4). In conclusion, while the most predictive variables for the presence of renal scarring among children presenting with
a UTI were male gender, age ≥ 27 months in girls, and grades IV–V reflux, the best predictor of new scar formation was presence
of previous renal scarring. 相似文献

AbstractBackground/Objective: Salmonella spondylodiskitis is an uncommon type of vertebral infection. The aim of this study was to present a case of progressive paraplegia caused by Salmonella spondylodiskitis and epidural abscess after endoscopic cholecystectomy.Methods: The patient underwent posterior instrumentation and posterior fusion between T6 and T12, hemilaminotomies at levels T8-T9-T10, and drainage of the abscess. Through a left thoracotomy, anterior T8-T10 corpectomy, debridement, anterior stabilization, and fusion were conducted.Results: Fifteen months later, final follow-up showed no complications secondary to the vertebral and hip surgeries, and neurological status improved to Frankel grade E. Laboratory investigations showed no evidence of Salmonella infection.Conclusion: Immunocompromised patients who undergo endoscopic intervention are vulnerable to Salmonella infections. One must consider Salmonella infection in those who develop acute progressive spondylodiskitis. 相似文献

OBJECTIVE: As the endothelium and inflammatory cells play a crucial role in the development of collaterals after a sudden or slowly progressing stenosis of coronary arteries, the levels of soluble endothelial adhesion molecules (CAMs) including vascular cell adhesion molecule (VCAM-1) intercellular adhesion molecule-1 (ICAM-1) and E-selectin were compared between patients with poor coronary collaterals and patients with well-developed collaterals. METHODS: In the study, 97 non-diabetic subjects with single-vessel disease were included. Collateral supply to the stenotic coronary artery was determined by angiographic grading system of 0-3 (Rentrop et al. J Am Coll Cardiol 1985; 5:587-592). Serum levels of adhesion molecules were measured by enzyme-linked immunosorbent assay. RESULTS: Patients were divided into two groups according to the collateral degree (group A: 50 patients with grade 0 and 1; group B: 47 patients with grade 2 and 3 collaterals). The groups were well matched with respect to baseline clinical and angiographic characteristics. Levels of soluble VCAM-1 (mean+/-SEM; 875+/-26.6 versus 742.7+/-35.1 ng/ml; P=0.004), ICAM-1 (322.4+/-12.4 versus 269.4+/-13.3 ng/ml; P=0.005), and E-selectin (43.6+/-2.6 versus 33+/-2.4 ng/ml; P=0.004) were found to be significantly higher in group A in comparison with group B. In addition, when patients were divided into four groups according to the collateral degree, patients with grade 0 collaterals had the highest values and those with grade 3 collaterals had the lowest values for all these molecules. CONCLUSIONS: We concluded that poor collateral circulation is associated with increased levels of soluble CAMs in patients with obstructive coronary artery disease. However, further studies are needed to elucidate the exact role of these inflammatory markers in the setting of poor collateral circulation. 相似文献

A 7-year-old girl was admitted because of dyspnea on exertion and palpitations. Her symptoms had gradually worsened for the last 6 months. She had physical features of the Marfan syndrome. Transthoracic echocardiography showed an ascending aortic aneurysm, severe aortic regurgitation, and mildly dilated left ventricle. Because of marked aortic aneurysm and severe aortic regurgitation, the patient was treated with a beta-blocker and an angiotensin converting enzyme inhibitor. Surgery was refused by her parents. We describe here a child with Marfan syndrome in whom significant dilatation of the ascending aorta and severe aortic regurgitation is encountered and major cardiovascular complications of Marfan syndrome were reviewed. 相似文献

Heterotopic pancreas is a relatively common variant of foregut embryologic dystopia that can be described as pancreatic tissue found outside the normal anatomic location, being independent from vascular supply of normal pancreas. Having all features of pancreatic tissue except for the major duct structures, this ectopic tissue may be clinically recognized when pathologic changes take place. Inflammation, hemorrhagic or obstructive states, and eventually malignancy-related problems may become a diagnostic challenge for clinician and finally lead to consequences of misdiagnosis. In this article we will discuss a case of heterotopic pancreatic tissue located in gastric cardia, which was diagnosed preoperatively as gastrointestinal stromal tumor.Key words: Ectopic pancreas, Pseudocyst, Gastrointestinal stromal tumor, MisdiagnosisHeterotopic (ectopic) pancreas is defined as the presence of pancreatic tissue in an aberrant site that is not anatomically and vascularly connected to the pancreas proper.1,2 Ectopic pancreatic tissue is most commonly found in the duodenum (particularly the second portion), ampulla, stomach (prepyloric antrum), and upper jejunum; it can also occur in the liver, biliary tract, Meckel''s diverticulum, and several other sites such as large bowel, spleen, omentum, mediastinum, lung, thyroid, and even brain.1–6 The heterotopic pancreatic tissue is usually located in the submucosa and/or the muscularis or subserosa.1,2,4Practically any pancreatic pathology can also occur in the heterotopic pancreatic tissue including acute pancreatitis and neoplastic transformation.1,4,7,8 Episodes of acute pancreatitis may cause local inflammation and typical pancreatitis-related complications in the host organ. The ectopic pancreatic tissue can lead to ulceration and bleeding in the cases located beneath a mucosa. Being a mass-forming lesion, it may also result in luminal obstruction (particularly in the prepyloric antrum).1,4Although it is a relatively common congenital anomaly (0.5% to 13% in autopsy series), in most cases heterotopic pancreas remains clinically silent and is found incidentally during surgery or an endoscopic and/or radiological investigation.1,9 Heterotopic pancreas may be confused with other solid tumors of the host organ.Heterotopic pancreas in the stomach is usually located in the prepyloric area.10 We report here an unusual case of heterotopic pancreas with a pseudocyst formation in the gastric cardia mimicking gastrointestinal stromal tumor. 相似文献

Extramedullary hematopoiesis being an important feature of agnogenic myeloid metaplasia (AMM), a chronic myeloproliferative disease of clonal origin, may affect the kidneys, but this condition is usually asymptomatic. Until now, there is only one reported case of nephrotic syndrome associated with AMM. We present a patient with AMM who had nephrotic syndrome and whose renal biopsy revealed membranous glomerulonephritis together with renal extramedullary hematopoiesis. 相似文献

Aim: To evaluate efficacy and tolerability of topotecan treatment for recurrent small cell lung carcinoma.Patients and Methods: A total of 62 patients were evaluated retrospectively. Statistical analysis was performedusing GraphPad Instat (version 3.05). Results: DFifty five of patients (89%) were male and 7 (11%) were female.Median age was 56.7±9.3 (34-75). Forty eight of patients (80%) were extensive stage (ES) at the time of diagnosis.Fifty of the patients (80.6 Medical Oncology Clinic) were given median 5.36 cycles of cisplatin-etoposide (2-8 cycles).Time to recurrence was 15.6±6.13 weeks in patients with limited stage (LS) and 6.3±3.82 weeks in extensivestage (ES) (p<0.0001). Overall survival was 14.0±6.08 months in ES and 17.9±6.88 months in LS. The differencebetween two groups was statistically meaningful (p=0.0447). The overall survival of the patients was 14.8±6.43months (4.5-40 months). In terms of survival, there was no difference between males and females (p=0.1171).In 17 (27%) patients who were refractory to topotecan or in whom progression occurred other chemotherapieswere used. Conclusion: Small cell lung cancer is chemosensitive, but recurrences occur in short time. Otherchemotherapy regimens are used in progression. Topotecan is one of them. Patients who were young and in whomrecurrences occur late had given better response to topotecan. Because of the retrospective nature of the study,we couldn’t reach the records exactly and consequently, rate and duration of response couldn’t be calculated.In recurrent SCLC topotecan is one of the treatment choices. But both hematological and non hematologicalside effects should be taken into consideration. 相似文献
