Background
Ipsilateral recurrence after nephron-sparing surgery (NSS) is rare, and little is known about its specific determinants.Objective
To determine clinical or pathologic features associated with ipsilateral recurrence after NSS performed for renal cell carcinoma (RCC).Design, setting, and participants
We analysed 809 NSS procedures performed at eight academic institutions for sporadic RCCs retrospectively.Measurements
Age, gender, indication, tumour bilaterality, tumour size, tumour location, TNM stage, Fuhrman grade, histologic subtype, and presence of positive surgical margins (PSMs) were assessed as predictors for recurrence in univariate and multivariate analysis by using a Cox proportional hazards regression model.Results and limitations
Among 809 NSS procedures with a median follow-up of 27 (1–252) mo, 26 ipsilateral recurrences (3.2%) occurred at a median time of 27 (14.5–38.2) mo. In univariate analysis, the following variables were significantly associated with recurrence: pT3a stage (p = 0.0489), imperative indication (p < 0.01), tumour bilaterality (p < 0.01), tumour size >4 cm (p < 0.01), Fuhrman grade III or IV (p = 0.0185), and PSM (p < 0.01). In multivariate analysis, tumour bilaterality, tumour size >4 cm, and presence of PSM remained independent predictive factors for RCC ipsilateral recurrence. Hazard ratios (HR) were 6.31, 4.57, and 11.5 for tumour bilaterality, tumour size >4 cm, and PSM status, respectively. The main limitations of this study included its retrospective nature and a short follow-up.Conclusions
RCC ipsilateral recurrence risk after NSS is significantly associated with tumour size >4 cm, tumour bilaterality (synchronous or asynchronous), and PSM. Careful follow-up should be advised in patients presenting with such characteristics. 相似文献2.

Background
Modern histopathology is able to differentiate chromophobe renal cell carcinomas (cRCCs), oncocytomas, and chromophobe–oncocytic hybrid RCCs; however, the true frequency and clinical courses of these tumors remain unclear.Objective
To determine the clinical course of hybrid RCC.Design, setting, and participants
Ninety-one surgically treated tumors, originally classified as oncocytoma or cRCC, were slide reviewed and reclassified by an experienced uropathologist. Immunohistochemical cytokeratin-7 (CK7) staining was used to distinguish oncocytoma (CK7 positive in <10% of the cells) and hybrid RCCs (CK7 positive in >10% of the cells).Interventions
Radical tumor nephrectomy or nephron-sparing surgery.Measurements
Recurrence-free and tumor-specific survival.Results and limitations
Overall, 16 tumors (17.6%) were hybrid RCCs, 32 tumors were cRCCs, and 43 tumors were pure oncocytomas. Perinephric tissue invasion (pT3a) was found in one pure oncocytoma and in two hybrid RCCs. The pathologic stage for cRCC was pT1 in 50% of tumors (n = 17), pT2 in 23.5% of tumors (n = 8), and pT3a in 26.5% of tumors (n = 9). Low-grade RCC was found in 76.5% of tumors (n = 26), and vascular invasion was found in 11.8% of tumors (n = 4). After a mean follow-up of 50 mo, no oncocytomas or hybrid RCCs were found, but two cRCCs had recurred. The 3-yr tumor-specific survival rates for patients with oncocytoma, hybrid RCCs, and cRCC were 100%, 100%, and 97%, respectively.Conclusions
Hybrid RCCs are more common than expected. The survival rate is 100% for both hybrid RCCs and oncocytomas. Hybrid RCCs may be candidates for active surveillance, and surgery may be unnecessary. CRCCs should be treated because a small proportion of these tumors exhibit aggressive clinical courses. 相似文献3.

Background
Surgical repair of pectus excavatum (PE) has become more popular due to improvements in the minimally invasive Nuss procedure. The pre-surgical assessment of PE patients requires Computerized Tomography (CT), as the malformation characteristics vary from patient to patient.Objective
This work aims to characterize soft tissue thickness (STT) external to the ribs among PE patients. It also presents a comparative analysis between the anterior chest wall surface before and after surgical correction.Methods
Through surrounding tissue segmentation in CT data, STT values were calculated at different lines along the thoracic wall, with a reference point in the intersection of coronal and median planes. The comparative analysis between the two 3D anterior chest surfaces sets a surgical correction influence area (SCIA) and a volume of interest (VOI) based on image processing algorithms, 3D surface algorithms, and registration methods.Results
There are always variations between left and right side STTs (2.54 ± 2.05 mm and 2.95 ± 2.97 mm for female and male patients, respectively). STTs are dependent on age, sex, and body mass index of each patient. On female patients, breast tissue induces additional errors in bar manual conception. The distances starting at the deformity's largest depression point at the SCIA are similar in all directions. Some diverging measures and outliers were found, being difficult to find similar characteristics between them, especially in asymmetric patients.Conclusion
The Nuss procedure metal bar must be modeled according to each patient's special characteristics. The studied relationships between STT and chest surface could represent a step forward to eliminate the CT scan from PE pre-surgical evaluation. 相似文献5.

Background
Radiofrequency ablation (RFA) of renal cell carcinoma (RCC) is used to obtain local control of small renal masses. However, available long-term oncologic outcomes for RFA of RCC are limited by small numbers, short follow-up, and lack of pathologic diagnoses.Objective
To assess the oncologic effectiveness of RFA for the treatment of biopsy-proven RCC.Design, setting, and participants
Exclusion criteria included prior RCC or metastatic RCC, familial syndromes, or T2 RCC. We retrospectively reviewed long-term oncologic outcomes for 185 patients with sporadic T1 RCC. Median follow-up was 6.43 yr (interquartile range [IQR]: 5.3–7.7).Outcome measurements and statistical analysis
The chi-square test and Wilcoxon rank-sum tests were used to compare proportions and medians, respectively. Disease-specific survival and overall survival (OS) were calculated using Kaplan-Meier analysis, then stratified by tumor stage, and comparisons were made using log-rank analysis. The 5-yr disease-free survival (DFS) and OS rates are reported. A p value <0.05 was considered statistically significant.Results and limitations
Median tumor size was 3 cm (IQR: 2.1−3.9 cm). Tumor stage was T1a: 143 (77.3%) or T1b: 42 (22.7%). Twenty-four patients (13%) were retreated for residual disease. There were 12 local recurrences (6.5%), 6 recurrences in T1a disease (4.2%) and 6 in T1b disease (14.3%) (p = 0.0196). Median time to recurrence was 2.5 yr. Local salvage RFA was performed in six patients, of whom five remain disease free at 3.8-yr median follow-up. Tumor stage was the only significant predictor of DFS on multivariate analysis. At last follow-up, 164 patients (88.6%) were disease free (T1a: n = 132 [92.3%]; T1b: n = 32 [76.2%]; p = 0.0038). OS was similar regardless of stage (p = 0.06). Five patients developed metachronous renal tumors (2.7%). Four patients developed extrarenal metastases (2.2%), three of whom died of metastatic RCC (1.6%).Conclusions
In poor surgical candidates, RFA results in durable local control and low risk of recurrence in T1a RCC. Higher stage correlates with a decreased disease-free survival. Long-term surveillance is necessary following RFA. Patient selection based on tumor characteristics, comorbid disease, and life expectancy is of paramount importance. 相似文献6.

Objective
To evaluate the impact of methicillin resistance in Staphylococcus aureus bacteremia (SAB) on mortality and length of stay in burn patients.Design
Retrospective cohort study.Setting
A 750-bed tertiary care university hospital in Cologne, Germany.Patients
Patients registered in the database of the burn intensive care unit (BICU) between 1989 and 2009 with complete data sets (n = 1688).Results
Over the 21-year study period, 74 patients with SAB were identified; 33 patients had methicillin-resistant S. aureus (MRSA) and 41 methicillin-susceptible S. aureus (MSSA). Comparing the MRSA with the MSSA population the following parameters were significantly different in the univariate analysis: BMI (27.2 kg/m2 vs. 23.6 kg/m2; P = 0.05), extent of deep partial thickness burns (17.8% vs. 9.0% of total body surface area; P = 0.007), antibiotic requirement on admission (45.5% vs. 22.0%; P = 0.046), median length of hospitalization prior SAB (24 days vs. 7 days; P < 0.001), packed red blood cells administration (47.6 units vs. 26.1 units; P = 0.003), intubation requirement (100% vs. 80.5%; P = 0.007), intubation period (43.5 days vs. 26.8 days; P = 0.008), catecholamine requirement (90.9% vs. 61.0%; P = 0.004), sepsis (60.6% vs. 34.1%; P = 0.035) and organ failures (81.8% vs. 39.0%; P < 0.001). Regarding outcome parameters, methicillin resistance was not significantly related with mortality (adjusted OR 1.55, 95% CI 0.56–4.28; P = 0.40) and length of BICU stay after SAB (Kaplan–Meier analysis log-rank test P = 0.32; Cox's proportional hazards regression HR 1.22, 95% CI 0.65–2.27, P = 0.535) in the univariate and multivariate analyses.Conclusion
Our data suggest that methicillin resistance is not associated with significant increases in mortality and length of BICU stay among burn patients with SAB. 相似文献7.

Background
Laparoscopy is currently challenging the role of the open approach for nephron-sparing surgery (NSS), yet comparative studies on this issue are scant.Objective
To compare surgical, oncologic, and functional outcomes after laparoscopic partial nephrectomy (LPN) and open partial nephrectomy (OPN).Design, setting, and participants
We undertook matched-pair (age, sex, tumour size) analysis of patients who underwent elective NSS for renal masses either by laparoscopic (Klagenfurt) or open (Vienna) access.Measurements
Surgical data, complications, histologic and oncologic data, and short- and long-term renal function of the open and laparoscopic groups were compared.Results and limitations
In total, 200 patients matched for age, sex, and tumour size entered the study after either LPN or OPN and were followed for a mean of 3.6 yr. Surgical, ischemia, and hospitalisation times were shorter in the LPN group (p < 0.001). Blood loss and complication rates were comparable in both groups. Malignant tumours were pT1 stage renal-cell cancer only in both groups. The positive surgical margin (PSM) rate was 4% after LPN and 2% after OPN (p = 0.5); positive margins were not a risk factor for disease recurrence. Kaplan-Meier estimates of 5-yr local recurrence-free survival (RFS) were 97% after LPN and 98% after OPN (p = 0.8); the respective numbers for distant free survival were 99% and 96% (p = 0.2). Five-year overall survival (OS) for patients with pT1 stage renal cell carcinoma (RCC) was 96% after LPN and 85% after OPN. The decline in glomerular filtration rate at the last available follow-up (LPN: 10.9%; OPN: 10.6%) was similar in both groups (p = 0.8). We recognise the retrospective nature, limited follow-up, and sample size as shortcomings of this study.Conclusions
In experienced hands, LPN provides similar results compared to open surgery. PSM rates were comparable after LPN and OPN. Current experience questions the indication of secondary nephrectomy in these patients. 相似文献8.

Background
Nebulized antibiotics are used to locally treat colonizations of multi-resistant organisms. Prior systemic nephrotoxic antibiotic use with serum creatinine rises warranted an alternative therapy in 69 ventilator-dependent patients with persisting sputum cultures and need for ventilatory support.Materials and methods
Following IRB approval, retrospective patient data were reviewed. Analysis included comparison of these 69 patients (71 treatments) to 142 Gram-negative infected burn patients matched for age and burn size.Results
Mean pooled age and burn wound percent for the 71 triplicates (n = 211 patients) were 55.6 ± 18.3 years and 27.4 ± 22.3% burns. Fifty-seven of 69 (83%) patients had inhalation injuries and 54 of 69 (78%) patients survived. Nebulizations averaged 6.8 ± 3.3 days (range 3–12 days). Serum creatinine rose in 2 patients receiving colistimethate nebulizations, known to cause nephrotoxicity following nebulization. Triplicate comparisons via ANOVA noted prolonged ventilatory support (F = 13.39; p ? 0.05) and length of stay (F = 6.11; p ? 0.5). Variance was attributed to the sicker nebulized patients. Twenty-four inhalation injury-only triplicates further confirmed that nebulized patient subgroup was more ill.Conclusion
Short duration antibiotic nebulization may allow higher intra-tracheal antibiotic concentrations and may facilitate weaning from the ventilator by reducing bacterial bioburden. 相似文献9.
Background
Approximately 10–20% of recurrences in patients treated with nephrectomy for renal cell carcinoma (RCC) develop beyond 5 yr after surgery (late recurrence).Objective
To determine features associated with late recurrence.Design, setting, and participants
A total of 5009 patients from a multicenter database comprising 13 107 RCC patients treated surgically had a minimum recurrence-free survival of 60 mo (median follow-up [FU]: 105 mo [range: 78–135]); at last FU, 4699 were disease free (median FU: 103 mo [range: 78–134]), and 310 patients (6.2%) experienced disease recurrence (median FU: 120 mo [range: 93–149]).Interventions
Patients underwent radical nephrectomy or nephron-sparing surgery.Outcome measurements and statistical analysis
Multivariable regression analyses identified features associated with late recurrence. Cox regression analyses evaluated the association of features with cancer-specific mortality (CSM).Results and limitations
Lymphovascular invasion (LVI) (odds ratio [OR]: 3.07; p < 0.001), Fuhrman grade 3–4 (OR: 1.60; p = 0.001), and pT stage >pT1 (OR: 2.28; p < 0.001) were significantly associated with late recurrence. Based on accordant regression coefficients, these parameters were weighted with point values (LVI: 2 points; Fuhrman grade 3–4: 1 point, pT stage >1: 2 points), and a risk score was developed for the prediction of late recurrences. The calculated values (0 points: late recurrence risk 3.1%; 1–3 points: 8.4%; 4–5 points: 22.1%) resulted in a good-, intermediate- and poor-prognosis group (area under the curve value for the model: 70%; 95% confidence interval, 67–73). Multivariable Cox regression analysis showed LVI (HR: 2.75; p < 0.001), pT stage (HR: 1.24; p < 0.001), Fuhrman grade (HR: 2.40; p < 0.001), age (HR: 1.01; p < 0.001), and gender (HR: 0.71; p = 0.027) to influence CSM significantly. Limitations are based on the multicenter and retrospective study design.Conclusions
LVI, Fuhrman grade 3/4, and a tumor stage >pT1 are independent predictors of late recurrence after at least 5 yr from surgery in patients with RCC. We developed a risk score that allows for prognostic stratification and individualized aftercare of patients with regard to counseling, follow-up scheduling, and clinical trial design. 相似文献10.

Background
Currently, tumor grade is the best predictor of outcome at first presentation of noninvasive papillary (Ta) bladder cancer. However, reliable predictors of Ta tumor recurrence and progression for individual patients, which could optimize treatment and follow-up schedules based on specific tumor biology, are yet to be identified.Objective
To identify genes predictive for recurrence and progression in Ta bladder cancer at first presentation using a quantitative, pathway-specific approach.Design, setting, and participants
Retrospective study of patients with Ta G2/3 bladder tumors at initial presentation with three distinct clinical outcomes: absence of recurrence (n = 16), recurrence without progression (n = 16), and progression to carcinoma in situ or invasive disease (n = 16).Measurements
Expressions of 24 genes that feature in relevant pathways that are deregulated in bladder cancer were quantified by real-time polymerase chain reaction on tumor biopsies from the patients at initial presentation.Results and limitations
CCND3 (p = 0.003) and HRAS (p = 0.01) were predictive for recurrence by univariate analysis. In a multivariable model based on CCND3 expression, sensitivity and specificity for recurrence were 97% and 63%, respectively. HRAS (p < 0.001), E2F1 (p = 0.017), BIRC5/Survivin (p = 0.038), and VEGFR2 (p = 0.047) were predictive for progression by univariate analysis. Multivariable analysis based on HRAS, VEGFR2, and VEGF identified progression with 81% sensitivity and 94% specificity. Since this is a small retrospective study using medium-throughput profiling, larger confirmatory studies are needed.Conclusions
Gene expression profiling across relevant cancer pathways appears to be a promising approach for Ta bladder tumor outcome prediction at initial diagnosis. These results could help differentiate between patients who need aggressive versus expectant management. 相似文献11.

Objectives
Endotracheal tube (ETT) and its inflated cuff are likely to induce specific reactivity at the emergence time. In ICU, the tolerance of the ETT cuff could be a part of patient agitation and increased of sedation.Materials and methods
Using specific ICU ETT cuff (thin polyurethane cuff), we perform an in vitro evaluation of diffusion of lidocaine and alkalinized lidocaine (L-B) across the PU cuff for a long duration. We evaluate the safety of this procedure by a daily injection into the cuff.Results
With lidocaine alone, we observed a low rate of diffusion through the cuff (< 8% over 24 h), whereas the L-B solution had a high diffusion (> 90% over 24 h). The released profiles were similar from day 0 to day 8, and no cuff rupture was reported over the 8-day study.Conclusion
The safety, controlled release, and lack of deleterious effects on cuff membrane were confirmed. In case of unexpected cuff rupture, an adequate determination of the mixture allows to obtain a safe solution with the achievement of a physiological pH (7.4) and the small dose of lidocaine (40 mg). 相似文献12.
Background
Conventional renal cell carcinoma (RCC) is the most common renal cancer. As the metastatic conventional RCC is practically incurable, there is a need for markers to estimate the tumour aggressiveness.Objective
To identify and characterise new marker(s) associated with the poor prognosis of conventional RCC.Design, Setting, and Participants
RNA from 24 conventional RCCs was analysed for global gene expression by Affymetrix U133 Plus 2.0 arrays. Tissue microarrays containing 224 renal tumours including 87 conventional RCCs were used for immunohistochemistry. Cell lines HD2, HD48, HA344 and HA465 established in our laboratory were used for invasion assay and zymography.Measurements
Serum amyloid A 1 (SAA1) was found to be upregulated in conventional RCCs and it has been analysed by quantitative RT-PCR and immunohistochemistry on TMAs to establish the correlation between SAA1 protein expression and patient survival by uni and multivariate analysis. The effect of SAA1 on tumour cell behaviour in vitro has also been examined by invasion assay and zymography.Results and Limitations
SAA1 RNA is expressed in conventional RCC samples of patients with poor prognosis. Immunohistochemistry of 72 conventional RCCs with a 5 yr follow up showed a correlation between SAA1 expression and the clinical outcome of disease. Stimulation of conventional RCC cell lines with recombinant SAA1 increased the expression of metalloproteinase (MMP)-9 and the invasive potential of tumour cells. Limitation of the study is a relatively small number (72) of patients having follow up.Conclusion
SAA1 seems to be a useful marker to estimate the prognosis of conventional RCCs. 相似文献13.

Background
For elderly individuals with localized renal cell carcinoma (RCC), surgical intervention remains the primary treatment option but may not benefit patients with limited life expectancy.Objective
To calculate the trade-offs between surgical excision and nonsurgical management (NSM) with respect to competing causes of mortality.Design, setting, and participants
Relying on a cohort of Medicare beneficiaries, all patients with nonmetastatic node-negative T1 RCC between 1988 and 2005 were abstracted.Intervention
All patients were treated with partial nephrectomy (PN), radical nephrectomy (RN), or NSM.Outcome measurements and statistical analysis
Cancer-specific mortality (CSM) and other-cause mortality (OCM) rates were modeled through competing-risks regression methodologies. Instrumental variable analysis was used to account for the potential biases associated with measured and unmeasured confounders.Results and limitations
A total of 10 595 patients were identified. In instrumental variable analysis, patients treated with PN (hazard ratio [HR]: 0.45; 95% confidence interval [CI], 0.24–0.83; p = 0.01) or RN (HR: 0.58; 95% CI, 0.35–0.96; p = 0.03) had a significantly lower risk of CSM than those treated with NSM. In subanalyses restricted to patients ≥75 yr, the instrumental variable analysis failed to detect any statistically significant difference between PN (HR: 0.48; p = 0.1) or RN (HR: 0.57; p = 0.1) relative to NSM with respect to CSM. Similar trends were observed in T1a RCC only.Conclusions
PN or RN is associated with a reduction of CSM among older patients diagnosed with localized RCC, compared with NSM. The same benefit failed to reach statistical significance among patients ≥75 yr. The harms of surgery need to be weighed against the marginal survival benefit for some patients. 相似文献14.

Background
Prostate cancer antigen 3 (PCA3) and v-ets erythroblastosis virus E26 oncogene homolog (TMPRSS2-ERG) gene fusions are promising prostate cancer (PCa) specific biomarkers that can be measured in urine.Objective
To evaluate the diagnostic and prognostic value of Progensa PCA3 and TMPRSS2-ERG gene fusions (as individual biomarkers and as a panel) for PCa in a prospective multicentre setting.Design, setting, and participants
At six centres, post–digital rectal examination first-catch urine specimens prior to prostate biopsies were prospectively collected from 497 men. We assessed the predictive value of Progensa PCA3 and TMPRSS2-ERG (quantitative nucleic acid amplification assay to detect TMPRSS2-ERG messenger RNA [mRNA]) for PCa, Gleason score, clinical tumour stage, and PCa significance (individually and as a marker panel). This was compared with serum prostate-specific antigen and the European Randomised Study of Screening for Prostate Cancer (ERSPC) risk calculator. In a subgroup (n = 61) we evaluated biomarker association with prostatectomy outcome.Outcome measurements and statistical analysis
Univariate and multivariate logistic regression analysis and receiver operating curves were used.Results and limitations
Urine samples of 443 men contained sufficient mRNA for marker analysis. PCa was diagnosed in 196 of 443 men. Both PCA3 and TMPRSS2-ERG had significant additional predictive value to the ERSPC risk calculator parameters in multivariate analysis (p < 0.001 and resp. p = 0.002). The area under the curve (AUC) increased from 0.799 (ERSPC risk calculator), to 0.833 (ERSPC risk calculator plus PCA3), to 0.842 (ERSPC risk calculator plus PCA3 plus TMPRSS2-ERG) to predict PCa. Sensitivity of PCA3 increased from 68% to 76% when combined with TMPRSS2-ERG. TMPRSS2-ERG added significant predictive value to the ERSPC risk calculator to predict biopsy Gleason score (p < 0.001) and clinical tumour stage (p = 0.023), whereas PCA3 did not.Conclusions
TMPRSS2-ERG had independent additional predictive value to PCA3 and the ERSPC risk calculator parameters for predicting PCa. TMPRSS2-ERG had prognostic value, whereas PCA3 did not. Implementing the novel urinary biomarker panel PCA3 and TMPRSS2-ERG into clinical practice would lead to a considerable reduction of the number of prostate biopsies. 相似文献15.

Background
Renal insufficiency is a significant complication of Wilms tumor treatment in the 5% with bilateral disease. Nephron-sparing surgery (NSS) is recommended after neoadjuvant chemotherapy initially. However, the role of NSS in recurrent disease is unknown. We reviewed our experience to assess the feasibility and oncologic and functional outcomes of repeat NSS for children with recurrent disease.Methods
A retrospective review was performed of all children treated at our institution for bilateral, favorable histology (FH) Wilms tumor. Patients undergoing repeat NSS for locally recurrent disease were identified. The outcomes evaluated included tumor recurrence, renal function, and patient survival.Results
Since 2001, 36 children with bilateral FH Wilms tumor have been treated at our institution. Eight patients (22%) underwent repeat NSS for locally recurrent disease. Two patients had a second local recurrence and underwent a third NSS. Six patients are alive without disease (75%) with an average follow-up of 4.5 years. Two patients have died, each with blastemal-predominant histology at repeat NSS. The surviving patients have normal renal function, although two patients require medical management of hypertension.Conclusions
Our experience suggests that repeat NSS for local recurrence of FH bilateral Wilms tumor is feasible and affords acceptable oncologic outcome with preservation of renal function. However, more aggressive therapy may be required for patients whose recurrence has blastemal-predominant histology, given the poor outcome for these patients in our series. 相似文献16.

Background
Nephron-sparing surgery (NSS) can safely be performed with slightly higher complication rates than radical nephrectomy (RN), but proof of oncologic effectiveness is lacking.Objective
To compare overall survival (OS) and time to progression.Design, setting, and participants
From March 1992 to January 2003, when the study was prematurely closed because of poor accrual, 541 patients with small (≤5 cm), solitary, T1–T2 N0 M0 (Union Internationale Contre le Cancer [UICC] 1978) tumours suspicious for renal cell carcinoma (RCC) and a normal contralateral kidney were randomised to NSS or RN in European Organisation for Research and Treatment of Cancer Genito-Urinary Group (EORTC-GU) noninferiority phase 3 trial 30904.Intervention
Patients were randomised to NSS (n = 268) or RN (n = 273) together with limited lymph node dissection (LND).Measurements
Time to event end points was compared with log-rank test results.Results and limitations
Median follow-up was 9.3 yr. The intention-to-treat (ITT) analysis showed 10-yr OS rates of 81.1% for RN and 75.7% for NSS. With a hazard ratio (HR) of 1.50 (95% confidence interval [CI], 1.03–2.16), the test for noninferiority is not significant (p = 0.77), and test for superiority is significant (p = 0.03). In RCC patients and clinically and pathologically eligible patients, the difference is less pronounced (HR = 1.43 and HR = 1.34, respectively), and the superiority test is no longer significant (p = 0.07 and p = 0.17, respectively). Only 12 of 117 deaths were the result of renal cancer (four RN and eight NSS). Twenty-one patients progressed (9 after RN and 12 after NSS). Quality of life and renal function outcomes have not been addressed.Conclusions
Both methods provide excellent oncologic results. In the ITT population, NSS seems to be significantly less effective than RN in terms of OS. However, in the targeted population of RCC patients, the trend in favour of RN is no longer significant. The small number of progressions and deaths from renal cancer cannot explain any possible OS differences between treatment types. 相似文献17.

Background
Multifocal renal cell carcinoma (RCC) has been reported in up to 25% of all radical nephrectomy specimens. Modern imaging tends to underestimate the rate of multifocality. Recognition of multifocality before treatment may guide physicians and patients to the type of intervention and tailor long-term follow-up.Objective
Our aim was to develop and assess preoperative nomograms to predict occult multifocal RCC.Design, setting, and participants
We evaluated 560 consecutive patients undergoing radical nephrectomy for clinically localized suspected sporadic RCC between 2000 and 2008 in a tertiary center. Clinically manifest multifocal lesions were excluded. Logistic regression models were used to assess the potential risk factors of occult multifocality with and without pathologic variables that may be available with preoperative biopsy. Nomograms were developed and assessed for diagnostic properties.Interventions
All patients underwent radical nephrectomy.Measurements
Assessments of risk factors for occult multifocal RCC were obtained using regression models and nomograms.Results and limitations
The incidence of occult multifocality was 7.9%. Significantly associated predictors of multifocality were male gender, family history of malignancy other than RCC, radiographic size of the lesion, histologic subtype other than clear cell, and Fuhrman grade IV. The two designed nomograms had 0.75 and 0.82 concordance indices, respectively.Conclusions
Our data suggest that occult multifocal RCC is more frequently associated with small (2–4 cm) renal lesions. Male gender, family history of kidney cancer, histologic subtype, and grade are strongly associated with an increased risk of occult multifocal RCC. The developed nomograms had good predictive accuracy that was enhanced when combined with pathologic variables. 相似文献18.

Background
Wound infection is one of the major complications in acute and chronic wound healing. Antiseptic solutions and wound irrigating agents are routinely used for therapy and prevention in healthcare today. Even if wound exudate contains total protein concentrations up to 9.3% and albumin concentrations up to 2.7% its influence to the antibacterial efficacy of these agents is barely investigated.Materials and methods
This study analyzed the antibacterial effect of polyhexanide biguanide (PHMB) agents (PHMB-concentration 0.005–0.1%) against Staphylococcus aureus and methicillin-resistant-S. aureus (MRSA) after 2 min incubation in presents of albumin in different concentrations (0–3%) in a standardized quantitative suspension assay.Results
A significant decrease of the antibacterial activity against S. aureus was shown for a PHMB-concentration of 0.005% from 0.3% albumin (p < 0.05), respectively highly significant from 0.75% (p < 0.01) on. Thereby the loss of antimicrobial effect was presented as a linear correlation to the rising concentration of albumin. Furthermore a reduction of the antibacterial activity against MRSA in comparison to S. aureus was presented, for albumin concentrations from 3% on highly significant (p < 0.01).Conclusion
The study showed that albumin causes a significant decrease of the antibacterial potency of PHMB-based antiseptics. Furthermore a diminished potency of the investigated substances for MRSA-contaminated wounds must be taken in consideration. If in vitro experiments show a significant decrease of antibacterial efficacy in the presence of albumin a sufficient activity of PHMB-based agents in clinical practice, especially in cases of exuding wounds or dried-up exudates, cannot be expected. 相似文献19.

Background
A retrospective review was carried out to evaluate the clinical presentation of children with epididymal cysts (EC) and outcome of management at our institution.Methods
There were 49 patients with EC in this series. The diagnosis of EC was made by physical examination and confirmed by ultrasound (US).Results
The average age at presentation was 10.7 years (2 months–16 years). Scrotal mass (n: 22) and pain (n: 21) were the most frequent symptoms. Seven patients were lost to follow-up. The cysts were solitary in 32 patients and multiple in 10 patients. The mean value of cysts was 6.7 mm (2–20 mm). The cyst localisations were 22 in left, 16 in right, and bilateral in 4 patients. Complete involution of cysts was detected in 14 children. The average involution time was 11.2 months (1–37 months). In 20 cases, a decrease in cyst size was found. Cyst excision was performed in 8 patients with persistent scrotal pain or no cyst involution observed during follow-up.Conclusion
Conservative management of epididymal cysts is practical. However, surgical excision is recommended in patients with intractable scrotal pain or if the cyst size does not seem to involute. 相似文献20.
