Abstract Introduction: Partial nephrectomy (PN) via open or minimally invasive (MI) techniques is the referent standard for managing renal cell carcinoma (RCC) whenever possible. Outcomes of MIPN in the obese patient population are incompletely defined. We investigate the feasibility of MIPN in obesity class I-III patients via comparison of surgical outcomes to those with a lower body mass index (BMI).
Materials and methods: The electronic medical records of 184 consecutive patients undergoing MIPN via laparoscopic (n = 109) or robotic (n = 75) techniques were reviewed. Patients were classified into the following patient cohorts stratified by BMI:… More >

Abstract Introduction: The aim of this retrospective study was to evaluate the impact of stapling devices use on overweight and obese bladder cancer patients treated with radical cystectomy (RC).
Materials and methods: Fifty-two overweight and 24 obese patients underwent open RC for muscle invasive bladder cancer. Bladder removal was performed using standard suture technique (SST) or multifire autosuture articulated vascular Endo-GIA (eG). Twenty-three overweight and 11 obese patients formed the SST arms and the remaining 29 overweight and 13 obese patients formed the eG arms. Intra and postoperative parameters and early postoperative complications (30 days) using the… More >

Abstract Introduction: To explore further the association of baseline health and gender with small renal mass pathology as approximately 20% of those masses are benign and women are twice as likely as men to have benign pathology.
Materials and methods: We conducted retrospective chart reviews of patients with renal masses ≤ 4 cm who underwent partial and radical nephrectomy from 1998 to 2012. Multivariable logistic regression analysis was performed to determine demographic and clinicopathologic factors associated with malignant pathology.
Results: In our cohort of 1726 patients, compared to patients with benign pathology, those with malignant pathology included a higher… More >

Abstract Introduction: To develop a classification tree for the preoperative prediction of benign versus malignant disease in patients with small renal masses.
Materials and methods: This is a retrospective study including 395 consecutive patients who underwent surgical treatment for a renal mass < 5 cm in maximum diameter between July 1st 2001 and June 30th 2010. A classification tree to predict the risk of having a benign renal mass preoperatively was developed using recursive partitioning analysis for repeated measures outcomes. Age, sex, volume on preoperative imaging, tumor location (central/peripheral), degree of endophytic component (1%–100%), and tumor axis position… More >

Abstract Inflammatory myofibroblastic tumor (IMT) of the kidney is a rare and benign condition often confused with renal malignancy based on clinical presentation and radiologic evaluation that has commonly been treated with nephrectomy. Utilizing renal mass biopsy to help diagnose and guide therapeutic intervention is increasing but has not been universally adopted to this point. We present a case of an incidentally found atypical renal mass in a 71-year-old female diagnosed as inflammatory myofibroblastic tumor of the kidney after core needle biopsy. This tumor was managed conservatively without surgical intervention and resolved spontaneously. More >

Abstract Introduction: Renal masses are commonly managed by partial nephrectomy (PN) or active surveillance (AS). We assessed the impact of patient demographics and clinical indices in determining treatment decisions of renal masses between these two options.
Materials and methods: We retrospectively reviewed our renal mass database to retrieve demographic and clinical records of patients who underwent immediate PN or entered a ≥12 month period of AS during February 1999 to May 2014. Age, gender, body mass index (BMI), Charlson Comorbidity Index (CCI) score, follow up time, tumor size, tumor location, renal invasion, creatinine, and estimated glomerular filtration… More >

Abstract This article deals the Hall and ion slip currents on free convection flow, heat and mass transfer of an electrically conducting couple stress fluid through porous channels with chemical reaction, Soret and Dufour effects. Assume that there is symmetric suction or injection along the expanding or contracting walls, which are maintained at different constant temperatures and concentrations. The governing partial differential equations are reduced to nonlinear dimensionless ordinary differential equations using the similarity transformations and solved numerically by the method of quasilinearization. The effects of various parameters on non-dimensional velocity components, temperature distribution and concentration More >

Abstract Natural hydrolysable chestnut tannin extracts used to partially substitute phenol in Phenol-Formaldehyde (PF) resins for phenolic rigid foams were analysed by matrix-assisted desorption ionization time of fl ight (MALDI-TOF) mass spectrometry. PF only, chestnut only and PF-chestnut copolymerised oligomer types and distribution were determined. MALDI-TOF analyses of a PF control resin (with the same molar ratio) and of chestnut tannin extracts were performed in order to identify the peaks of molecular weights corresponding to copolymers of chestnut tannins with phenol and formaldehyde.

Abstract The effect of fire on growth and nutritive value of Saccharum griffithii Munro ex Boiss-ravennae (Linn.) Murr. hybrid, a low palatable perennial grass in the semi-arid region of the highlands of Balochistan, Pakistan, was evaluated during 2008 and 2009. Prescribed fire treatments were applied in February 2008 and 2009 at the dormant stage of vegetation. Different growth parameters (tiller height, tiller number/plant), forage production (fresh, dry) and nutritive value (crude protein, ash) were compared with control (unburnt) plots. Fire increased the number of tillers, and the fresh and dry forage production in both years. Fire also More >
