In each model, they evaluated the role of BMI on specific outcomes. The eGFR was calculated using the Cystatin-C based formula of Rule. The average BMI at follow-up was 26.65±5.04 kg/m [23]. In the prospective study by Ibrahim et al, hypertension, kidney function, general health status, and quality of life were evaluated in 255 LKDs [24]. GFR was measured by iohexol clearance and estimated by MDRD. LKDs were matched to controls from the National Health and Nutrition Examination Survey 2003-2004 and 2005-2006 [24]. Tavakol et al followed 98 LKDs with matched controls from the National Health and Nutrition Examination Survey 2005-2006 in a prospective study examining kidney-related outcomes [25]. The GFR was calculated using MDRD. They calculated total urine protein and albumin excretion (abnormal when values > 150 and 30 mg/d, respectively). Multivariate logistic regression and linear regression models helped determine the independent association between BMI at donation and kidney-related outcomes [25]. The prospective study of 46 LKDs by Taner et al evaluated the impact of older age, obesity, and hypertension on the compensatory response of the remaining kidney five years post donation [26]. The 11 obese LKDs and 9 hypertensive LKDs were compared to 16 standard LKDs. The mean BMI of obese LKDs was 38.1±2.2 kg/m compared to standard LKDs which 22.6±1.2 kg/m. GFR was measured by I-iothalamate clearance [26]. Kerkeni et al retrospectively evaluated 189 LKDs and assessed both post-operative and long-term consequences of nephrectomy based on BMI [27]. Outcomes for overweight and obese LKDs were compared to those with BMI <25 kg/m. The mean BMI at the time of donation was 26.5±4.8 kg/m, with 33% of LKDs being overweight and 21% obese. Kidney function was assessed by creatinine clearance [27]. The study by Gracida et al evaluated long-term kidney-related outcomes in 628 LKDs. There were 81 LKDs who were obese prior to donation and 16 with hypertension [28]. They compared outcomes with 422 LKDs without risk factors. Mean BMI was 32.8 kg/m in the obese group and 24.7 kg/m in the standard group. The kidney function was measured using creatinine clearance and the method of GFR calculation was not mentioned [28].

A 75-year-old man with worsening renal function after catheter ablation developed moderate proteinuria and underwent a renal biopsy. Findings on light, immunofluorescence, and electron microscopy were all compatible with membranous nephropathy. Moreover, one occluded interlobular artery contained a pathognomonic, biconvex, needle-shaped cleft, which indicated a cholesterol crystal emboli. The degree of proteinuria was in parallel with the number of eosinophils, which indicated a close relationship between MN disease activity and renal atheroembolism.

Averrhoa carambola (Star fruit/ Kamranga) and Avorrhoa bilimbi are two such commonly used traditional remedies. They belong to family Oxalidaecae and contain high-levels of oxalic acid. AKI may occur after consuming concentrated juice due to deposition of oxalate crystals in the renal tubules. Here we present two patients who developed AKI after ingestion of freshly made juice from A. bilimbi and star fruit. Both patients were diabetic and the juice was ingested on empty stomach with the belief of improving glycemic status. Initial presentation was GI upset in both scenarios. Patient with A. bilimbi toxicity had diabetic nephropathy and required hemodialysis. Renal biopsy revealed deposition of polarizable oxalate crystals in the patient who consumed A. bilimbi and acute tubular necrosis in the patient with star fruit toxicity. All cases regained normal renal function within three months. We also present a patient who ingested raw fish gallbladder as a remedy for asthma. The patient presented with AKI within five days of ingestion and required hemodialysis. His highest serum creatinine was 10.4mg/dl and fell to 1.7 mg/dl after four weeks. Cyprinol and related compounds in fish gallbladder are thought to be the cause of acute tubular necrosis in such cases. The fourth patient developed AKI with rhabdomyolysis after consuming a locally made energy drink. He also required dialysis and serum creatinine gradually improved from 7.2mg/dl to 1.4mg/dl at discharge. The possibility of toxicity of caffeine, adulteration with other chemicals or ascorbic acid toxicity causing oxalate nephropathy could not be excluded. All four patients developed AKI caused after ingesting easily available products and are presented here for public awareness. We believe proper knowledge and education can reduce toxin induced AKI in our society.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"10 1","pages":"20-28"},"PeriodicalIF":0.0,"publicationDate":"2017-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48867540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ARHGAP24 gene product is a recently recognised important player in podocyte interaction with the glomerular basement membrane. The ARHGAP24 gene encodes a protein involved in regulating cell motility, membrane structure and polarity. Mutations in the gene have been showin vitro to cause cell membrane ruffling. Case Presentation: We report a novel missense mutation in exon 4 (c.[284G>A]; p.[Arg95Gln]) of the ARHGAP24 gene in a child that presented with SRNS at four years of age. Renal biopsy demonstrated unusual polypoid changes of the glomerular basement membrane (GBM). Conclusion: We propose this novel ARHGAP24 mutation as causative for SRNS associated with unusual polypoid basement membrane changes. These biopsy findings, in association with ARHGAP24 mutation and clinical nephrotic syndrome are a novel finding. This finding may advance the understanding of ARHGAP24 gene product function.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"9 1","pages":"88-93"},"PeriodicalIF":0.0,"publicationDate":"2016-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68066563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This was a cross-sectional study of three months duration (August-October 2014) in adult women on maintenance hemodialysis (HD) at three HD facilities in Cameroon. Patients with active psychiatric disease, infection or uncontrolled congestive heart failure were excluded. We use the Rosen questionnaire for evaluating female sexual function (FSFI), the Beck depression Inventory (BDI) and the short form (SF-36) of WHOQOL- BREF questionnaire to evaluate the quality of life (QOL). Logistic regressions were used to investigate the predictors of sexual function disorders. Results: We included 52 women with the mean age of 38±13 years (min-max: 18-69), with 31 (62%) being of child-bearing age (18-44 years). All participants had at least one sexual function abnormality including sexual dysfunction (75%), abnormalities of the menstrual cycle (83%), and sexual inactivity (30%). In women of child-bearing age, reported menstrual disorders were: irregular menses (45%), non-gravid amenorrhea (40%), oligo-menorrhea (25%), poly-menorrhea (25%), metrorrhagia (6%), and menorrhagia (3%). Ten of the 31 women had more than one menstrual disorder. Sexual dysfunction included: decreased sexual desire (56%), decreased sexual arousal (39%), decreased vaginal lubrication (49%), and failure to achieve orgasm (46%), sexual dissatisfaction (51%), and dyspareunia (36%). Advanced age ( p = 0.0046), depression ( p<0.0001), anemia ( p=0.0005) and poor quality of life were negatively associated with sexual dysfunction. Sexual inactivity ( p = 0.035) was equally associated with poor quality of life. Conclusion: Our results suggest that disorders of sexual function are common in women on maintenance hemodialysis, and are associated with depression, poor quality of life, advanced age, and anemia.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"9 1","pages":"51-59"},"PeriodicalIF":0.0,"publicationDate":"2016-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68067070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
