Case Report - Rhabdomyolysis due to hair dye poisoning: An emerging threat

Rhabdomyolysis can be caused by a variety of physical,chemical, metabolic, infective and toxic causes. We present two patients who developed rhabdomyolysis after consumption of hairdye containing paraphenylene diamine. Both of them developed renal, liver and respiratory failure requiring renal replacement. We were able to save one patient whereas the other died. Intentional hair dye poisoning is an emerging threat. Early recognition of the complications and prompt treatment is necessary for a successful outcome

Percutaneous CAPD catheter insertion by a nephrologist versus surgical placement: A comparative study

Peritoneal dialysis catheter (PDC) for continuous ambulatory peritoneal dialysis is inserted into the abdominal cavity either by a surgeon, interventional radiologist or nephrologist. Various innovations have been made in the methodology adopted in the placement of the PDC. We compared the percutaneous approach for PDC insertion with the open surgical technique. From January 2006 to May 2007, 25 of the 46 catheters were successfully inserted using the percutaneous Seldinger technique. The incision size (2.6 ± 0.7 vs 7.3 ± 0.6 cm) and the length of hospital stay (11.9 ± 5.9 vs 17.3 ± 6.8 d) were considerably less in the percutaneously placed group compared to the surgically placed group. Early initiation of exchanges and reduction in the expenses were other important advantages of this method

Childhood Bartter’s syndrome: An Indian case series

This is a retrospective analysis of children diagnosed with Bartter’s syndrome (BS) between 2001 and 2009 in our hospital. Seven children (six males) were diagnosed with BS. The mean age at presentation was 6.5 ± 4.9 months. The presenting features were failure to thrive,vomiting, polyuria, and dehydration. All children were normotensive at admission. The children exhibited alkalemia (pH, 7.58 ± 0.03), hypokalemia (serum potassium, 2.62 ± 0.47 mEq/l), hypochloremia (serum chloride, 82.83 ± 16.7 mEq/l), and hyponatremia (serum sodium, 126.85 ± 3.56 mEq/l). Disproportionate urinary wasting of sodium, potassium, and chloride were seen. The diagnosis was confirmed by elevated serum levels of both renin and aldosterone with normotension. Indomethacin or ibuprofen therapy resulted in marked improvement in general condition of these children. In conclusion, a high index of suspicion should be entertained in children with failure to thrive to diagnose BS. Therapy with NSAIDs leads to marked improvement in the general well being

ANCA negative pauci-immune glomerulonephritis with systemic involvement

Systemic vasculitides (SV) are a group of diseases with multi system involvement and varied clinical presentation. Anti-neutrophil cytoplasmic antibody (ANCA) testing has high sensitivity and specificity for SV. We describe the clinical course of four patients who had pauci-immune glomerulonephritis with systemic involvement without serological ANCA positivity; they were followed up for a cumulative 55 patient months. The mean Birmingham vasculitis score score was 23. All four had systemic symptoms with arthralgias and fever (100%). Neurological manifestations were seen in two patients (66%). Accelerated hypertension was seen in one. One patient had pulmonary renal syndrome. Renal manifestation was characterized by nephrotic range of proteinuria with glomerular hematuria in all (100%) and severe renal failure requiring dialysis in three (66%). At admission the mean blood urea was 146 ± 19 mg% and mean serum creatinine was 5.6 ± 1.9 mg%. Renal biopsy revealed focal proliferative glomerulonephritis with crescents only in 20-30% of glomeruli. There was significant chronic interstitial involvement in two patients (66%). Therapy with pulse steroids, cyclophosphamide, and mycophenolate mofetil (MMF) was effective in three patients while one died with lung hemorrhage. In conclusion, majority of patients with ANCA negative pauci-immune glomerulonephritis have multi-system involvement at admission. Renal biopsy is characterized by focal proliferative lesions with crescents and significant chronic interstitial fibrosis. Immunosuppressive drugs in the form of corticosteroids, MMF and cyclophosphamide bring about marked renal recovery in most patients

Tunneled central venous catheters: Experience from a single center

In the past vascular surgeons were called in to place tunneled central venous catheter (TVC) for hemodialysis patients. Advent of percutaneous technique has resulted in an increasing number of interventional nephrologists inserting it. A single centre three year audit of 100 TVCs with a cumulative follow up of 492 patient months is presented here. From 2007 to 2010, 100 TVCs were placed by nephrologists in a percutaneous fashion in the operative room or the interventional nephrology suite. Those who completed minimum of three months on the catheter were included in analysis. There were 69 males and 31 females with a mean age of 52.3±13.6 years.(range: 25-76). Chronic glomerulonephritis was the commonest cause of CKD (45%) followed by diabetes (39%).Right internal jugular vein was the preferred site (94%). TVC was utilized as the primary access to initiate dialysis in 25% of patients in whom a live donor was available for renal transplant. The blood flow was 250-270 ml/min. The Kaplan-Meier analysis showed that 3 months and 6 months catheter survival rates were 80% and 55%, respectively. The main complications were exit site blood ooze, catheter block and kink. Catheter related bacteremia rate was low at 0.4/1000 patient days. Primary cause of drop out was patient death unrelated to the TVCs. Those under the age of 40 years showed better survival, but there was no bearing of gender, catheter site, and etiology of CKD on survival. Tunneled central venous catheters could find a niche as the primary access of choice for pretransplant live donor renal transplants in view of its immediate usage, high blood flows, low infection rates and adequate patency rates for 3-6 months
