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.

Abstract

Background: A single self-rated health (SRH) assessment is associated with clinical outcome and mortality, but the biological process linking SRH with immune status remains incompletely understood.

Objectives: To examine the association between SRH and inflammation in apparently healthy individuals.

Methods: Our analysis included 13,773 apparently healthy individuals attending the Tel Aviv Sourasky Medical Center for periodic health examinations. Estimated marginal means of the inflammation-sensitive biomarkers [i.e., highly sensitive C-reactive protein (hs-CRP) and fibrinogen] for the different SRH groups were calculated and adjusted for multiple potential confounders including risk factors, health behavior, socioeconomic status, and coexistent depression.

Results: The group with the lowest SRH had a significantly higher atherothrombotic profile and significantly higher concentrations of all inflammation-sensitive biomarkers in both genders. Hs-CRP was found to differ significantly between SRH groups in both genders even after gradual adjustments for all potential confounders. Fibrinogen differs significantly according to SRH in males only, with low absolute value differences.

Conclusions: A valid association exists for apparently healthy individuals of both genders between inflammation-sensitive biomarker levels and SRH categories, especially when comparing levels of hs-CRP. Our findings underscore the importance of assessing SRH and treating it like other markers of poor health.

Background: The medical workforce shortage worldwide varies for different residencies.

Objectives: To determine future gaps in medical specialties in Israel by means of a model and to identify trends and considerations among medical students when they choose their residencies.

Methods: The gap (Gi) assessment model was based upon current demand (Di) and existing (Ei) status for each residency, using the formula [Gi=(Di-Ei)/Ei]. Ei represented the proportion of specific residencies in 2006–2010 out of all Israeli residency graduates and Di was based upon questionnaires filled out by medical students at Sackler and Hadassah medical schools in Tel Aviv and Jerusalem respectively (N=909).

Results: The largest relative shortages (Gi ranges from -1 to 1) were in Pathology (G=-1), Rehabilitation Medicine (-0.9), Radiology (-0.8), General Practice (-0.8) and Anesthesiology (-0.8). The highest relative demands were in Surgical subspecialties (2.9) and Obstetrics/Gynecology (OB/GYN) (1.6). More females than males chose residencies in OB/GYN (19.5% vs. 7.1%, P < 0.001) and pediatrics (28.1% vs. 15.4%, P < 0.001). Surgery subspecialties (9% vs. 23.7%, P < 0.001) were male-predominant. The workload consideration was rated higher among females, while income was rated higher among males. Among students in clinical years, compared to pre-clinical, there was a decline in the selection of some professions, including Surgical subspecialties (9.7% vs. 19.5%, P < 0.001).

Conclusions: The suggested model, based on a survey of demand and current or projected future needs, can be used to assess gaps and plan early interventions. Programs at the level of medical school may affect residency preferences. The decline in selection of surgical professions and the increasing workload as a consideration for residency choice should be given attention.

Background: Ritual circumcision in neonates may cause a urinary tract infection within 2 weeks of the procedure.

Objectives: To evaluate the prevalence of urinary tract infection among Jewish male circumcised neonates (¡Ü 28 days old) evaluated for fever in the emergency room.

Methods: All available medical records of neonates presenting to the pediatric emergency room for evaluation of fever over a 10 year period were reviewed. Data included gender, ethnic background, age in days on presentation to the emergency room, age in days when circumcision was performed (in males ¡Ý 8 days of age), and results of urine, blood and cerebrospinal fluid cultures. Families of males older than 8 days of age who had a UTI[1] were contacted by telephone to verify the circumcision status when the infant presented to the ER[2], to ascertain whether the circumcision was performed ritually by a mohel*
or by a physician, and, when not recorded in the chart, to verify the day of life on which circumcision was performed.

Results: Among neonates older than 8 days of age, 60 (24.7%) of the 243 febrile Jewish males had a UTI, as compared to 12 (8.4%) of 143 females (P < 0.0001). In 39 of 54 male neonates (72%) for whom circumcision was performed ritually on the eighth day of life, UTI occurred within 9 days of the circumcision. For females, there was no such clustering of UTI cases in the second week of life, nor during any other time period.

Conclusions: Febrile male neonates who have undergone ritual circumcision have a high prevalence of UTI and must be evaluated and treated accordingly.

Background: Hyperbilirubinemia of the newborn is common. Rarely is an underlying disease other than physiologic hyperbilirubinemia considered the cause of high bilirubin levels. Some of the laboratory tests recommended by the American Academy of Pediatrics are expensive and do not always lead to diagnosis.

Objective: To evaluate the efficacy of standard laboratory tests performed on newborn infants requiring phototherapy for hyperbilirubinaemia.

Methods: We conducted a retrospective chart review that included neonates born during a 6 month period with birth weight > 2500 g treated with phototherapy for hyperbilirubinemia (n=282) according to published guidelines. The main outcome measures were primary and maximal bilirubin values (mg/dl), time to jaundice (in days), the number of bilirubin tests undertaken and whether the patient showed abnormal functioning, and the number of days in follow-up.

Results: Thirty-three neonates (11.7%) were positive in at least one laboratory test (defined as "Abnormal" in our study), 45.5% of whom met the criteria for phototherapy during the first 48 hours of life. Among the newborns who were negative for all laboratory tests (defined as "Normal"), only 6.8% met phototherapy criteria within their first 48 hours of life (P < 0.001). In the Normal group there was a consistent decrease in total serum bilirubin values shortly after phototherapy was begun, while the Abnormal group presented an increase in serum bilirubin values during the first 12 hours of phototherapy. None of the infants had conjugated (direct) hyperbilirubinemia during the study period.

Conclusions: Most neonates presenting with a laboratory identifiable etiology for hyperbilirubinemia (i.e., hemolysis) can be distinguished from those who test negative, mainly based on the timing of presentation and response to phototherapy. A more meticulous selection of patients and reduction in the magnitude of routine laboratory testing can safely reduce discomfort to infants with hyperbilirubinemia as well as costs.

Background: Respiratory syncytial virus bronchiolitis is the single leading cause of pediatric admissions for infants in the first year of life, presenting regularly in epidemic proportions in the winter months and impacting in a major way on pediatric inpatient services.

Objective: To quantitate the burden of RSV[1] disease on a pediatric service with the purpose of providing a database for proper health planning and resource allocation.

Methods: We conducted a prospective 5 year study of documented RSV infections in a single pediatric service. RSV disease was confirmed by direct immunofluorescence testing of nasal swabs from all hospitalized cases of bronchiolitis.

Results: On average, 147 ± 17 cases of RSV bronchiolitis were admitted annually in the November–March RSV season, representing 7%–9% of admissions and 10%–14% of hospital days. There was a consistent male preponderance of admissions (55–64%) and 15–23% of admissions were patients less than 1 month old. In peak months RSV cases accounted for as many of 40% of the hospitalized infants and was the leading cause of over-occupancy (up to 126%) in the pediatric ward during the winter,

Conclusions: RSV infection is a major burden for pediatric inpatient services during the winter season. This recurrent and predictable “epidemic,” which regularly leads to over-occupancy, requires increased manpower (nursing) and resources (beds, pulse oximeters) to facilitate proper care. Since this annual event is not a surprise nor an unexpected peak, but rather a cyclical predictable epidemiological phenomenon, proper planning and allocation of services are crucial.

Background: The rate of cesarean section is increasing and recently exceeded 30% of all deliveries in the United States. Birth injuries during CS[1] are relatively rare. Femur fractures have a very low incidence during both vaginal delivery and CS.

Objectives: To assess our 10 year experience (2008–1997) in managing fractured femur during CS, including a typical case.

Methods: We reviewed the prevalence of femur fractures in two tertiary, academic, level one trauma center hospitals in Israel (Hadassah in Jerusalem and Soroka in Beer Sheva).

Results: During the study period 221,939 deliveries occurred in both hospitals. Of these, 17.6% were cesarean sections (33,990 CS). Of the total number of deliveries, the incidence of femur fracture was 0.082 per 1000 deliveries (17 fractures), and the incidence of femur fracture during CS was 0.308 per 1000 CS (12 fractures).

Conclusions: Cesarean section increases the risk of femur fractures (P < 0.001) with an odds ratio of 11.26 (confidence interval 3.97–31.97).

Background: Children report various types of fear in the context of hospitalization, such as fear of separation from the family, having injections and blood tests, having to stay in the hospital for a long time, and being told “bad news” about their health.

Objectives: To examine the effects of the “Teddy Bear Hospital” method on preschool children’s fear of future hospitalization.

Methods: The study group comprised 41 preschool children aged 3–6.5 years (mean 5.1 ± 0.7 years), and 50 preschool children, age matched and from a similar residential area, served as the control group. Assessment included a simple one-item visual analog scale of anxiety about hospitalization. This was assessed individually one day prior to the intervention and again a week after the intervention in both groups

Results: While baseline levels of anxiety were not different between groups [t(89) = .4, NS], children in the “Teddy Bear Hospital” group reported significantly lower levels of anxiety than the control group at follow-up

Conclusions: Our results indicate that by initiating a controlled pain-free encounter with the medical environment in the form of a “Teddy Bear Hospital,” we can reduce children’s anxiety about hospitalization.
