OBJECTIVE: Preoperative anemia in elderly patients undergoing surgery is prevalent and associated with adverse events; however, the interaction with other risk factors in patients with chronic limb-threatening ischemia (CLTI) is not well described. The purpose of this study was to assess the association between lower hematocrit (HCT) levels on admission and postoperative outcomes after infrainguinal bypass surgery. METHODS: Patients with CLTI undergoing nonemergent infrainguinal bypass were identified in the targeted vascular module of National Surgical Quality Improvement Program (NSQIP; 2011-2014)...

BACKGROUND: Mannitol is currently used as a renal protective agent to mitigate the effects of renal ischemia during nephron-sparing surgery (NSS). This routine practice lacks rigorous methodological study. OBJECTIVE: To assess the effect on renal function outcomes after surgery of mannitol infusion prior to renal ischemia during NSS. DESIGN, SETTING, PARTICIPANTS: This prospective, randomized, placebo-controlled, double-blind trial included 199 patients with a preoperative estimated glomerular filtration rate (eGFR) >45ml/min/1...

INTRODUCTION: Studies on outcomes and risk factors for neonatal nephrocalcinosis (NC) and renal calculi (RC) are limited, and often do not include controls for comparison. We conducted a case-control analysis to identify risk factors associated with NC and/or RC in neonates and studied the natural course of these anomalies. STUDY DESIGN: Infants diagnosed with NC/RC on ultrasound within the first year of life and corresponding gestational age- and gender-matched controls were identified from the neonatal intensive care unit database at our institution over a 10-year period...

PURPOSE OF REVIEW: The narrative review aims to discuss recent results and important knowledge gaps regarding acute kidney injury (AKI) in postoperative patients undergone major noncardiac surgery. RECENT FINDINGS: Postoperative AKI affects approximately one-fifth of patients after major surgery, but the incidence varies according to the type of surgery. Preexisting chronic kidney disease is a major risk factor for postoperative AKI. It carries a substantial risk for postoperative adverse outcomes, as well as long-term mortality and morbidity...

BACKGROUND: The creation of a diverting loop ileostomy is associated with the risk of readmission due to stoma-related complications. We hypothesized that the assessment of our institution-specific readmissions following ileostomy creation would help identifying at-risk groups which should be the focus of future preventative strategies. METHODS: Patients who underwent loop ileostomy formation from 2009 to 2013 were reviewed. We evaluated readmissions within 30 days after discharge following loop ileostomy construction...

Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. Clinically, this cancer is characterized by the presence of severe primary hyperparathyroidism. Diagnosis is based on histological examination but is not always easy. Surgery is the treatment of choice. We report the case of a 59-year old woman with a personal history of arterial hypertension and of recurrent renal lithiasis, presenting with diffuse bone pain associated with asthenia. Neck examination showed hard basi-cervical swelling with nonpalpable lower edge...

BACKGROUND: Adequate muscle relaxation is important for ensuring optimal conditions for intubation. Although acceleromyography of the adductor pollicis muscle is commonly used to assess conditions for intubation, we hypothesized that acceleromyography of the trapezius is more indicative of optimal intubating conditions. The primary outcome was the difference between both measurement sites with regard to prediction of good or acceptable intubating conditions. METHODS: Neuromuscular blockade after injection of rocuronium 0...

Intraoperative cell salvage (IOCS) has been widely used to reduce allogeneic blood transfusion and prevent blood transfusion related complications during surgery. However, due to the risk of transfusion related reaction, contamination, and immunological reaction, its use for tumor patients has been controversial and limited. To explore the feasibility of the application of IOCS in cancer patients, we reported 2 cases of renal cell carcinoma (RCC) with tumor embolism in IVC that underwent radical nephrectomy,and inferior caval venous thrombectomy receiving IOCS combined with leukocyte depletion filter (LDF) from August 2016 to November 2016 in our hospital...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

BACKGROUND: Remarkable improvement in the treatment of Peripheral Arterial Disease (PAD) has led to changes in revascularization strategies from traditional open surgery to less invasive endovascular management. However, few studies are available on gender disparities in patients with PAD treated via an endovascular approach. This study was designed to analyze gender related differences with respect to in-hospital outcomes in PAD patients. METHODS: Our data was obtained from National Inpatient Sample (NIS) 2012 through 2014...

A 75-year-old man with a history of chronic kidney disease (CKD) visited our emergency room after the sudden onset of severe right lower abdominal pain and nausea. Computed tomography (CT) showed right perirenal hematoma and renal tumor, which was diagnosed as a spontaneous rupture of the right renal tumor. It was difficult to correctly diagnose the tumor as benign or malignant with magnetic resonance imaging (MRI). Because of CKD, a shunt was implanted, and dynamic enhanced CT was performed. Dynamic enhanced CT showed a slightly enhanced area of the tumor, and it was diagnosed as renal cell carcinoma (RCC)...

Isolated renal mucormycosis is a rare entity in children. It is potentially fatal when not detected and managed early with antifungal therapy, and surgery as and when needed. We present two immunocompetent children who developed this infection and subsequently succumbed to it. The diagnosis was established postmortem on renal biopsy specimens. We also discuss the 9 cases of isolated renal involvement in children published in literature.

Clinical AKI, measured by serum creatinine elevation, is associated with long-term risks of adverse cardiovascular (CV) events and mortality in patients after cardiac surgery. To evaluate the relative contributions of urine kidney injury biomarkers and plasma cardiac injury biomarkers in adverse events, we conducted a multicenter prospective cohort study of 968 adults undergoing cardiac surgery. On postoperative days 1-3, we measured five urine biomarkers of kidney injury (IL-18, NGAL, KIM-1, L-FABP, and albumin) and five plasma biomarkers of cardiac injury (NT-proBNP, H-FABP, hs-cTnT, cTnI, and CK-MB)...

Deep endometriosis is usually defined as endometriosis infiltrating the peritoneum by >5 mm. It sometimes involves the ureter causing hydronephrosis in 5% of cases. The latter is associated with 18% ureteral lesions. Ureteral endometriosis is one of the rare causes of silent Kidney failure. The ureter obstruction can lead to urinary tract obstruction, hydronephrosis and hydroureters. The ureters are usually compressed externally by the endometriotic lesions surrounding it causing extrinsic ureteral endometriosis, and sometimes by pressure from the bulky adenomyotic uterus with paraureteral fibrosis...
