OBJECTIVE: To assess the diagnosis of children with coexisting pelvi-ureteric junction (PUJ) and vesico-ureteric junction (VUJ) obstruction, and the management of such patients, as having these two anomalies in the same ureter creates serious diagnostic difficulties, but any delay in diagnosis might cause a deterioration of renal function and affect the success of surgery to correct either anomaly. PATIENTS AND METHODS: We assessed the diagnostic difficulties and approach to 14 patients with coexistent PUJ and VUJ obstruction, who were treated surgically in our clinic between 1994 and 2005; we also review related published reports in English. RESULTS: Surgery was used in all 14 patients over the 11-year period; only five patients had an accurate diagnosis before surgery. Six patients were diagnosed with uroradiological techniques immediately after pyeloplasty; three were diagnosed on investigating an associated anomaly later. CONCLUSION: In children with coexisting PUJ and VUJ obstruction there are serious diagnostic problems; to prevent any deterioration in renal function due to obstruction, these anomalies require early diagnosis and treatment. For an early and accurate diagnosis, the coexistence of these two anomalies in the same ureter should be considered. 相似文献

Most metastatic spinal lesions (70%) are found at the thoracic level, 20% in the lumbar region, and 10% in the cervical region. A variety of benign and malignant tumours may arise in the lung, but the vast majority is bronchogenic carcinomas (90 to 95%). The aim of this study was to evaluate the lung cancer metastases to the vertebral column in terms of type, localisation and metastasis pattern. Between the years 1995 and 2003, 168 lung cancer patients with metastatic spinal tumour who had received radiotherapy and chemotherapy were retrospectively evaluated. The total number of vertebrae in which metastases were detected was 328. The most common site for metastasis was the thoracic spine. In 49 (29%) patients, there was only one vertebral involvement. Additional extravertebral bony metastases were present in 37 (22%) patients; the femur (20 patients) was the most common site. Only 25 of 168 patients were operated due to spinal cord compression leading to neurological deficit. The rest of the patients were treated by appropriate chemotherapy and radiotherapy protocols. The mean survival after diagnosis of vertebral metastasis was 7.1 months. Squamous cell carcinoma and adenocarcinoma are the lung cancers that mostly metastasise to vertebrae. Most of the metastases involve multiple spinal levels. After the diagnosis of vertebral metastasis, the mean survival is seven months. Pain relief and maintaining quality of life must be balanced with the patient's life expectancy, comorbidities and immunological, nutritional and functional status in treatment decision. 相似文献

PURPOSE: We aim to determine infections occurring in patients with non-small cell lung cancer during radiotherapy (RT). METHODS AND MATERIALS: A total of 181 patients had been treated with thoracic radiotherapy between October 1995 and December 1999. Radiotherapy was given using 1.8-3Gray (Gy) fraction daily, five fractions a week for a total dose of 59.4Gy (30-70.2Gy). A complete history was collected retrospectively for each patient. All microbiological examinations were performed according to the routine procedures of the hospital laboratory. Numeric and categoric variables were employed such as sex, age, performance status, histology, stage, chemotherapy, usage of corticosteroids, neutropenia, surgery, hospitalization, associated diseases, smoking during treatment, package per year of cigarette smoking, dose of radiotherapy, and response rates. RESULTS: Infections developed in 84 patients (46%, 84/181) during thoracic radiotherapy. A 101 episodes of infections developed in these patients. Most patients suffered from sputum production (65%), cough (59%), auscultation findings (31%) and fever (31%). Gram-negative bacteria were the most frequently isolated pathogens in the cultures of specimens (70%, 16/23 samples). Neoadjuvant chemotherapy (OR=4.81; 95% CI, 1.57-9.12; p=0.003) and neutropenia (OR=4.25; 95% CI, 1.44-6.89; p=0.009) were found as risk factors for influencing infection based on logistic regression analyses. Package per year of cigarette smoking was found statistically significantly higher in patients with infections than patients without infections (p=0.001). A slight increase in infections, which was of borderline statistical significance (p=0.07), was observed in patients age over 70. Ciprofloxacin and clarithromycin were the most frequently used agents in treatment. Median survival was 9 months in the patients with infection and 13 months in the 97 patients without infection. Overall survival seemed to be statistically significantly better in patients without infection than patients with infection (p=0.042) calculated using Kaplan-Meier method. Based on Cox regression analyses; overall survival was not correlated to presence of infection but associated with poor performance status (=80) (OR=2.35; 95% CI, 0.85-8.93; p=0.03), and usage of corticosteroids (OR=2.68; 95% CI, 0.98-6.72; p=0.01). The dose of radiation therapy >5940 cGy (OR=2.06; 95% CI, 0.72-7.18; p=0.007) and the absence of response to treatment (OR=2.45; 95% CI, 0.89-14.23; p<0.001) were also found to be risk factors for survival. CONCLUSIONS: Infections are important causes of morbidity and mortality in lung cancer patients. The control of infection in these patients may improve the survival. Predisposing factors and treatment management approaches in non-small cell lung cancer should be defined carefully. 相似文献

Intravascular large B-cell lymphoma (IVLBCL) is a very rare subtype of extranodal large B-cell lymphoma. It may involve various organ systems such as skin, liver, lung or kidney. Isolated kidney involvement of IVLBCL is also very rare. Herein we report a very rare case of isolated renal IVLBCL presented with fever of unknown origin, acute kidney injury and nephrotic syndrome. Diagnosis was suspected with isolated high renal 18F fluorodeoxyglucose uptake in positron emission tomography and confirmed with renal biopsy. Complete remission was obtained with combined chemotherapy including rituximab. We reviewed the English literature in terms of IVLBCL with renal involvement and we could only find 16 such cases. Accordingly, fever, AKI and nephritic syndrome are the most common presenting symptoms in renal intravascular lymphoma. 相似文献

A 14-year-old boy admitted to our clinic with a 20-day history of fever, cough and respiratory distress. Mediastinal enlargement was observed on chest radiograph. Computed tomography of the chest demonstrated a large posterior mediastinal mass. The histopathological examination of the mass revealed Burkitt's lymphoma. We report this case because primary posterior mediastinal involvement in Burkitt lymphoma is extremely rare in childhood. 相似文献

The aim of this study was to investigate the possible effects of ivabradine against doxorubicin (DOX)-induced cardiotoxicity in rats using hemodynamic parameters (electrocardiogram, heart rate (HR), and blood pressure), biochemical markers of oxidative stress, lactate dehydrogenase, aspartate transaminase, creatine kinase-MB, and histopathological analyses both in serum and tissue specimens. A total of 28 female rats were randomly assigned to 4 groups: (a) control (n?=?6 rats), (b) DOX group (n?=?7 rats), (c) DOX?+?ivabradine-treated group (n?=?8 rats), and (d) ivabradine group (n?=?7 rats). When the means of the four groups were compared, there was only a significant difference in the level of HR (p?0.05). DOX treatment caused more HR elevation when compared to the control group, whereas ivabradine application after DOX treatment significantly reduced HR levels. Cardiomyocytes were revealed as normal histology in the light of both hematoxylin and eosin staining and immunostaining methods (caspase-3 and bcl-2) in all groups. The present study reported the therapeutic effects of ivabradine against DOX-induced cardiotoxicity accompanied by the hemodynamic and biochemical parameters. 相似文献
