Urinary tract infection (UTI) is one of the most common bacterial infections among children. It is noted that the risk of renal damage from UTI is the greatest in children younger than five years, thus early diagnosis and prompt treatment are important. The aim of this study was to assess the incidence of UTI in children attending pediatric outpatient clinics in Zagazig and Tanta University Hospitals as tertiary care hospitals. Furthermore, we attempted to determine related risk factors, isolate the organisms that cause UTI in children, and study their antibiotic susceptibility patterns. This cross-sectional descriptive study was conducted on 1200 toddlers and children, (754 boys and 446 girls) aged between 30 months and seven years attending the pediatric outpatient clinics of Zagazig and Tanta University Hospitals. All patient groups were subjected to full medical history, physical examination, dipstick analysis by using both nitrite and leukocyte esterase (LE) detectors, microscopic examinations, and urine culture for cases with the positive LE, positive nitrite dipstick test for urine or positive for both LE and nitrite. The incidence of UTI among children included in the current study was 7%. Positive LE was seen in 112 (9.3%), nitrite positivity was seen in 94 (7.8%), and both LE and nitrite positivity in 34 (2.8%). Escherichia coli was the most common organism. Cefotaxime and amikacin were the most common sensitive antibiotics to the isolates.The global prevalence of type 2 diabetes mellitus (DM) in adults is increasing all over the world. Diabetic kidney disease (DKD) is one of the most common complications of DM. The aim of the present work is to study chronic kidney disease (CKD) in patients newly diagnosed with type 2 DM as regards incidence and associations. This is a comparative cross-sectional study. The study included 153 patients with newly diagnosed type 2 DM over the past six months. DKD was diagnosed if urinary albumin to creatinine ratio >30 mg/g in two out of three-morning urine samples collected within three to six months and/or estimated glomerular filtration rate (eGFR) less then 60 mL/min/1.73 m2 using 2009 CKD-Epidemiology Collaboration creatinine equation. DKD was present in 45.75% of patients. In our study, 54.9% of patients had microalbuminuria, 39.2% had macroalbuminuria, and 5.9% had severely increased albuminuria. As regards eGFR, 5.2% of patients had eGFR less then 60 mL/min/1.73 m2. https://www.selleckchem.com/products/avelestat-azd9668.html Regression analysis showed that increased levels of cholesterol, triglyceride, and glycated hemoglobin were associated with an increased likelihood of developing nephropathy while nonsmoking and elevated high-density lipoprotein cholesterol levels were associated with a reduction in that likelihood. DKD was present in a substantial proportion of our patients at diagnosis. Routine screening for DKD is recommended in all patients early at the onset itself of diagnosis with type 2 DM.Glomerulonephritis associated with anti-neutrophil cytoplasmic antibody (ANCA) vasculitis still has a high prevalence of end-stage renal disease (ESRD), particularly in patients with advanced renal failure at presentation. This study aims to evaluate the clinical and histo- pathological features of renal involvement and investigate factors associated with ESRD. Patients with renal biopsy-proven ANCA-associated glomerulonephritis were included retrospectively over a period of nine years (June 2007 to March 2016). The renal survival, defined as time to reach ESRD, was evaluated based on clinical parameters, histopathological classification, and renal risk score. A total of 37 patients with crescentic glomerulonephritis were included in the study. The average age was 54 ± 16 years (range 17-80) and 51.3% were female. Twenty-two patients were diagnosed with microscopic polyangiitis and 15 had granulomatosis with polyangiitis. The median glomerular filtration rate at presentation was 16.73 mL/min/1.73 m2. Thirty-five patients (94.5%) had renal failure at presentation and 23 patients (62.1%) required initial hemodialysis (HD) therapy. The pattern of glomerular injury was categorized as sclerotic in 48.6% of cases, crescentic in 24.3%, mixed in 24.3%, and focal class in 2.7%. Regarding renal risk score, we had five patients with low risk, 17 with intermediate risk and 15 with high risk. ESRD occurred in 47% of intermediate-risk group and 66% of the high risk group. During follow-up, 17 patients (45.9%) developed ESRD. Tobacco addiction (P = 0.02), alveolar hemorrhage (P = 0.04), hypertension (P = 0.04), initial HD (P = 0.04), and sclerotic class (P = 0.004) were associated with ESRD. In our patients, a sclerotic class was associated with a higher risk of ESRD, suggesting that histo- pathological classification is potentially an important parameter to predict outcomes in renal disease secondary to ANCA-associated vasculitis.Glomerular diseases are considered to be a significant cause of chronic kidney disease. Kidney biopsy continues to be an essential diagnostic tool. We review the renal biopsies which were done on children below the age of 14 years in the past 10 years (from January 2008 to September 2018) in a single tertiary pediatric hospital in Saudi Arabia to determine the patterns of renal disease among Saudi children as well-correlating clinical presentation with histopathological diagnosis. A total of 203 pediatric kidney biopsies were performed. The mean age was 7.3 ± 3.9 years (3 months to 14 years). There were 105 males and 98 females. The most frequent indication for renal biopsy was nephrotic syndrome in 58.9% of patients, followed by acute glomerulo- nephritis in 20.8%. Other indications included significant proteinuria, persistent microscopic hematuria, acute kidney injury of uncertain etiology, in the remaining 20% of biopsies. Clinical diagnosis was consistent with histopathological diagnosis in 92% of the cases. Minimal change disease was the most common cause of primary glomerular diseases in 37.4%, followed by focal segmental glomerulosclerosis in 20.2%. Lupus nephritis represents the most common cause of the secondary renal disease (8.4%). Complications of kidney biopsy were observed in only 16.3% of patients, of whom 9.9% had perirenal hematomas and 6.4% of the patients developed either microscopic hematuria or macroscopic hematuria.
