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.

A variety of skin infections are encountered in postrenal transplant setting. Though bacterial and fungal infections are more common, surprises are in store for us sometimes. We describe a patient who underwent renal transplant two years ago, presenting with a painless, mildly pruritic expanding skin rash over abdomen. Histological examination of the skin biopsy showed that stratum corneum had multiple burrows containing larvae and eggs of Sarcoptes scabiei. The patient was treated with ivermectin 12 mg weekly once for 2 doses along with topical 5% permethrin and permethrin soap bath. There was remarkable improvement in the skin lesions with complete resolution in two weeks. Norwegian or crusted scabies is caused by massive infestation with Sarcoptes scabiei var. hominis. It can be rarely encountered in the post-transplant setting, which underscores the importance of early diagnosis and treatment before secondary bacterial infection sets in.

The incidence of acute kidney injury (AKI) after cardiac surgery remains high. The nonspecific adenosine receptor antagonist aminophylline has been shown to confer benefit in experimental and clinical acute renal failure (ARF) due to ischemia, contrast media, and various nephrotoxic agents. We conducted a prospective open label trial to assess the effectiveness of aminophylline for prevention of renal impairment after cardiac surgery. One hundred and thirty-eight patients undergoing cardiac surgery were risk stratified as per Cleveland score to assess for prediction of AKI. Sixty-three patients received a bolus aminophylline of 5 mg/kg and a subsequent continuous infusion of 0.25 mg/kg/h for up to 72 h, while 75 patients received usual postoperative care. Serum creatinine concentrations were measured preoperatively and daily until day 5 after surgery and the glomerular filtration rate estimated using Cockcroft and Gault formula. Hourly urine output was recorded and patients assigned to respective RIFLE stage of AKI. Cleveland score ≥6 was associated with higher incidence of AKI: I and F (P<0.005). Number needed to treat, an insight into the clinical relevance of a specific treatment, is 8. These results suggest that the perioperative use of aminophylline infusion is associated with lower incidence of deterioration in renal function following cardiac surgery in high-risk patients.
