Disaster Management in a Nephrology Service: Lessons Learned from Hurricane Maria.

BACKGROUND: Puerto Rico suffered a major humanitarian -crisis after Hurricane Maria. We describe our experience with patients with renal disease in an academic medical center. SUMMARY: A comprehensive emergency response plan should be developed, shared and discussed with the team and the patients prior to the hurricane. The needs of the staff should not be ignored to ensure their ability to participate as responders. Physical damage to facilities, lack of basic services, shortage of disposable products, and the inability to get to treatment centers are the most common threats. Preemptive dialysis can avoid serious complications. A contingency plan to move patients to another center should be prearranged in case the unit is rendered nonfunctional after the storm. Patients must receive preventive education about fluid and dietary restrictions and the possible use of potassium binding drugs if they cannot reach a dialysis unit. A list of alternative drugs that could be used if patients are not able to fill their medications is required. The Internet and social media proved to be an invaluable communication tool. A registry of patients with updated contact information, as well as contact information for relatives and a physical address where an emergency rescue team can be dispatched is essential. Water safety should be reinforced. Key Message: Our experience showed us that preparing for the worst is not enough. Advanced planning of a streamlined response is the best tactic to decrease harm.

Fluid and electrolyte disorders in the newborn: sodium and potassium.

Tubular development continues after birth in full and pre-term infants. As the survival of premature infants increases, serious imbalances in water and electrolytes in this group have become more prevalent. A diminished ability of the immature kidney to reabsorb water and respond to mineralocorticoids, a high excretion of filtered sodium, perinatal complications affecting tubular function, and the use of medications such as diuretics, indomethacin and amphotericin B, are common factors leading to sodium and potassium imbalances in this age group. Appropriate diagnosis and treatment should be guided by a careful assessment of volume status, urine electrolytes and osmolality.

Pediatric Risk, Injury, Failure, Loss, End-Stage renal disease score identifies acute kidney injury and predicts mortality in critically ill children: a prospective study.

OBJECTIVES: To determine whether Pediatric Risk, Injury, Failure, Loss, End-Stage renal disease (pRIFLE) criteria serve to characterize the pattern of acute kidney injury in critically ill pediatric patients. To identify if pRIFLE score will predict morbidity and mortality in our patient's cohort. DESIGN: Prospective cohort. SETTING: Multidisciplinary, tertiary care, ten-bed PICU. PATIENTS: A total of 266 patients admitted to PICU from November 2009 to November 2010. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The incidence of acute kidney injury in the PICU was 27.4%, of which 83.5% presented within 72 hours of admission to the PICU. Patients with acute kidney injury were younger; weighed less; were more likely to be on fluid overload greater than or equal to 10%; and were more likely to be on inotropic support, diuretics, or aminoglycosides. No difference in gender, use of other nephrotoxins, or mechanical ventilation was observed. Fluid overload greater than or equal to 10% was an independent predictor of morbidity and mortality. In multivariate analysis, acute kidney injury and failure categories, as defined by pRIFLE, predicted mortality, hospital length of stay, and PICU length of stay. CONCLUSIONS: In this cohort of critically ill pediatric patients, acute kidney injury identified by pRIFLE and fluid overload greater than or equal to 10% predicted increased morbidity and mortality. Implementation of pRIFLE scoring and close monitoring of fluid overload upon admission may help develop early interventions to prevent and treat acute kidney injury in critically ill children.

Cryptococcosis associated with crescentic glomerulonephritis.

Crescentic glomerulonephritis (CGN) is an uncommon form of renal injury in childhood. Whereas many infectious processes are known to be linked to CGN, fungal infections typically are not. This report describes an 11-year-old girl who presented with CGN, cutaneous anergy, and cryptococcal mediastinitis. Whereas cryptococcal disease in children is usually associated with immunodeficiency (inherited or acquired), extensive immunologic evaluation of the patient was notable only for relative CD4 lymphopenia with normal CD4/CD8 ratios. Testing for human immunodeficiency virus was negative. Clinical and diagnostic studies are presented, along with a review of the literature regarding glomerular disease and cryptococcal infections.
