Renal Salt-Wasting Syndrome Induced by Neoadjuvant Chemotherapy Containing Cisplatin - A Case Report.

Hyponatremia is one of the most common electrolyte abnormality seen in oncology practice. The underlying pathogenetic mechanism for chemotherapy-induced hyponatremia is renal salt-wasting syndrome (RSWS) and syndrome of inappropriate antidiuretic hormone secretion (SIADH). Fluid restriction is the treatment of choice in SIADH, whereas salt supplements is the mode of treatment in RSWS. Hence, differentiation between RSWS and SIADH is very important though difficult. Case reports of cisplatin (cis-dichloro-diammine-platinum-2)-induced RSWS and SIADH are rare in the literature. We report about a patient who developed hyponatremia, hypokalemia with excessive urinary excretion of sodium and potassium, renal glycosuria, and aminoaciduria on the third day of the first cycle of cisplatin-containing chemotherapy.

Salvage of infected tunneled hemodialysis catheters using 70% ethanol lock solution: A brief report.

Tunneled hemodialysis catheters are the lifeline to patients on maintenance hemodialysis with failed arteriovenous fistulas. However, thrombosis and infection are the main causes of reduced longevity of these accesses. According to IDSA guidelines, catheter-related infection with Pseudomonas and fungi are absolute indications for catheter removal. Considering the cost and difficulties in catheter replacement, for those in whom all accesses are exhausted, retaining the same catheter may be lifesaving. We would like to present two patients in whom, 70% ethanol instillation was used to eradicate infection with these organisms as confirmed by repeat cultures post procedure. Hemodialysis is being successfully continued through the same catheter.

Bile cast nephropathy causing acute kidney injury in a patient with nonfulminant acute hepatitis A.

Hepatitis A is usually a benign self-limiting disease with few or no extrahepatic manifestations. Acute hepatitis A causing severe renal dysfunction is not very common, although described. Patients developing renal dysfunction post hepatitis A infection usually have prerenal acute kidney injury (AKI) or acute tubular necrosis due to vomiting, diarrhea, and poor fluid replacement. However, if renal dysfunction persists, other causes need to be evaluated. The term cholemic nephrosis or more specifically bile cast nephropathy has been described in the setting of cholestatic jaundice and decompensated liver failure where bilirubin levels reach above 20 mg/dL. Herein, we describe the clinical course of a patient who developed acute hepatitis A with severe liver dysfunction and subsequently AKI which persisted for six weeks. Renal biopsy showed the evidence of bile cast nephropathy. After six weeks of hemodialysis, urine output improved. He slowly recovered both hepatic and renal functions.

Interstitial lung disease probably caused by imipramine.

Drugs are rarely associated with causing interstitial lung disease (ILD). We report a case of a 75-year-old woman who developed ILD after exposure to imipramine. To our knowledge, this is one of the rare cases of ILD probably caused due to imipramine. There is need to report such rare adverse effects related to ILD and drugs for better management of ILD.
