Background: Hypernatremic dehydration is a common and potentially life-threatening condition in children. There is currently no consensus as to the optimal strategy for fluid management. Objectives: To describe the relationship between the type, route and rate of fluids administered and the rate of decline in serum sodium (Na+) concentration. 

Methods: We reviewed the medical records of all children under the age of 2 years who were hospitalized with hypernatremic dehydration (serum Na+ ≥ 155 mEq/L) in Shaare Zedek Medical Center during the period 2001–2010. Collected data of 62 subjects included initial and subsequent serum Na+ levels, and rate and Na+ concentration of all intravenous and oral fluids administered until the serum Na+ reached ≤ 150 mEq/L.

Results: Median initial serum Na+ was 159.5 mEq/L (IQR 157–163, maximal value 170). The median rate of decline in serum Na+ until serum Na+ reached 150 mEq/L was 0.65 mEq/L/hr (IQR 0.45–0.95). Forty-two children received hypotonic oral fluids which accounted for approximately one-quarter of all fluids they received. There was no significant difference in the rate of decline in serum Na+ between those who consumed oral fluids and those who did not. Neither was there a correlation between the rate of IV fluids, receipt of oral fluids or the degree of dehydration, with the rate of decline in serum Na+. No child experienced an apparent short-term adverse outcome. 

Conclusions: A cumulative rate of 5.9 ml/kg/hr of IV fluid administration may reduce the serum Na+ to an acceptable rate (0.65 mEq/L/hr). Fluid therapy comprising up to 25% hypotonic oral fluids and 75% IV fluids high in Na+ concentration was not associated with any short-term adverse outcome in our patient population. 

 

Objectives: To add new cases of septicemia after rotavirus to the literature, review the few cases of septicemia after rotavirus that have been reported, calculate the incidence of septicemia in children hospitalized for rotavirus gastroenteritis, and discuss the characteristics of septicemia after rotavirus infection and implications for current pediatric practice.

Methods: We identified children whose illness was complicated by septicemia from among all hospitalizations at our facility for rotavirus gastroenteritis from May 1999 through May 2010. We also review the few cases reported in the English literature. 

Results: We identified two cases of septicemia from among 632 hospitalizations for rotavirus gastroenteritis in this time period, for an incidence rate of 0.32%, which is comparable to other estimates in the English literature. The typical course for cases of bacterial superinfection involves a second peak of high fever; other clinical signs are variable.

Conclusions: Septicemia after rotavirus gastroenteritis is a rare but dangerous entity. Early identification of a child developing bacterial superinfection after rotavirus, as in any case of sepsis, is of the utmost importance, as is obtaining blood cultures in a child with a rotavirus infection and a second fever spike. 

Background: Diarrhea is a leading cause of child mortality worldwide. Rotavirus is one of the most common causes of severe diarrhea and dehydration in children.

Objectives: To compare the demographic, clinical and laboratory characteristics of patients with rotavirus gastroenteritis to those with other causes of gastroenteritis.

Methods: The medical records of children aged 0–18 years hospitalized with acute gastroenteritis in our facility between 1 January 2004 and 31 March 2006 were retrieved. Patients with rotavirus gastroenteritis were compared with patients who were rotavirus negative.

Results: The study group comprised 533 patients; 202 tested positive for rotavirus and 331 tested negative. Compared to patients with rotavirus-negative gastroenteritis, patients with rotavirus-positive gastroenteritis had a higher incidence of vomiting (185/202 vs. 212/331, 92% vs.  64%, P < 0.001), lethargy (67 vs. 51, 33% vs. 15%, P < 0.001), and dehydration (81 vs. 78 vs. 40% vs. 24%, P < 0.001). The need for intravenous rehydration therapy and the duration of hospitalization were higher in patients with rotavirus gastroenteritis.

Conclusions: Vomiting and dehydration are more common in hospitalized children with rotavirus gastroenteritis than in children with gastroenteritis due to other causes.
 

Background: While the burden of rotavirus infection with regard to hospitalizations has been extensively investigated, there are sparse data regarding the impact and the cost of this infection on the ambulatory part of the health system in Israel.

Objectives: To investigate the burden of rotavirus infection on the ambulatory system in Israel.

Methods: Infants younger than 3 years old examined for acute gastrointestinal symptoms in four pediatric clinics had their stool tested for rotavirus. The parents were contacted 7–10 days later and questioned about the symptoms of illness, medications given, use of diapers, consumption of formula, and any loss of parents' workdays.

Results: Rotavirus was detected in 71 of the 145 stool samples tested (49%). A total of 51 parents responded to the telephonic survey. Patients' mean age was 15.4 months. Three patients were hospitalized due to the illness. The mean duration of fever was 1.7 days. Infants with rotavirus gastroenteritis had on average 2.25 days of vomiting and 7.5 days of diarrhea. The average number of workdays lost was 2.65 days per RVGE[1] case. The cost of the average case of RVGE in Israel is 257 euros; 69.64% of this cost (179 euros) is due to parental work loss.

Conclusions: Our results indicate that the economic impact of the ambulatory cases in Israel is quite significant.
