Background: Head injuries, especially in young children, are frequent and may cause long-lasting impairments.

Objectives: To investigate the outcome of head and other injuries caused by diverse mechanisms and of varied severity.

Methods: The population consisted of Jews and Arabs (n=792), aged 0–17 years old, hospitalized for injuries in six hospitals in Israel. Caregivers were interviewed during hospitalization regarding circumstances of the injury and sociodemographic variables. Information on injury mechanism, profile and severity, and length of hospitalization was gathered from the medical files. Five months post-injury the caregivers were interviewed by phone regarding physical limitations and stress symptoms.

 Results: Head injuries occurred in 60% of the children, and of these, 22.2% suffered traumatic brain injury with loss of consciousness (type 1). Among the rest, 22% of Jewish children and 28% of Arab children remained with at least one activity limitation, and no statistically significant differences were found among those with head or other injuries. The odds ratio for at least two stress symptoms was higher for children involved in transport-related injuries (OR[1] 2.70, 95% confidence interval 1.38–5.28) than for other mechanisms, controlling for injury profile. No association was found between stress symptoms and injury severity.

Conclusions: Most children had recovered by 5 months after the injury. Residual activity limitations were no different between those with head or with other injuries. Stress symptoms were related to transport-related injuries, but not to the presence of TBI[2] or injury severity.

Background: Leptin, a pleiotropic hormone, has been suggested to be part of an acute phase response during an inflammatory stimulus. Its correlation with other acute phase reactants during minor infection in children has not been investigated.

Objectives: To study the correlation between serum leptin levels to those of C-reactive protein, a well-documented acute-phase reactant, in a series of pediatric patients with acute minor infections.

Methods: Leptin and CRP[1] levels were measured in 62 blood samples of pediatric patients presenting with mild febrile illness who were admitted to Dana Children’s Hospital in Israel. All children were finally diagnosed as having minor infection based on the negative blood/urine cultures and favorable outcome.

Results: Serum leptin level was positively correlated with CRP (r² = 0.5), total white blood cells (r² = 0.33) and absolute neutrophil count (r² = 0.31). The regression coefficient was the highest between leptin and CRP.

Conclusions: Circulating leptin concentrations are positively correlated with CRP levels during acute minor infection in children visiting the emergency room for febrile illnesses. Our observation suggests that leptin is indeed a part of acute-phase proteins. The wide scattering showed that it is not a better marker in minor infections than CRP, but it may contribute to weight loss and anorexia seen in the minority of patients during mild infections.

Objectives: To define the length of time required to rehabilitate and discharge these patients, and to identify predictors of a prolonged or failed discharge process.

Methods: We conducted a retrospective chart review of patients admitted to the Respiratory Rehabilitation Unit at Alyn Hospital, Jerusalem, over a 4 year period.

Results: Of the 48 patients identified, 31 (64.7%) were eventually discharged, 13 (27.1%) remained hospitalized long-term, and 4 (8.3%) died during their hospitalization. The median length of hospitalization was 10 months: 6 months for purposes of rehabilitation therapy, and 4 months thereafter to resolve the logistics of discharge. Specific family characteristics – an unemployed father (odds ratio = 4.6, P = 0.02) and an additional family member with a disability (OR[1] = 5.8, P = 0.03) – as well as ongoing mechanical ventilation at the time of discharge (OR = 5.5, P < 0.01) were found to positively correlate with a prolonged or failed discharge process.

Conclusions:  Hospitalization in a pediatric respiratory rehabilitation unit may be prolonged for both medical and non-medical reasons, with the process of discharge home being particularly difficult in certain subsets of patients. A proactive discharge policy by hospitals, improved community support services, and legislation defining the rights of home-ventilated children may facilitate more efficient discharge home of these patients.

Background: Intramural duodenal hematoma generates partial or complete obstruction that develops slowly and progressively with a consequent delay in diagnosis. Many diagnostic and therapeutic measures remain debatable and justify a review of current management policy.

Objectives: To highlight the diagnostic and therapeutic steps in pediatric IDH[1].

Methods: The records of 12 children with post-traumatic IDH who were treated in the Hillel Yaffe Medical Center between 1986 and 2000 were retrospectively reviewed. Three of them had clotting disorders and were excluded. The interval between their admission and diagnosis as well as the therapeutic decisions were evaluated and analyzed.

Results: Nine children were treated for IDH. The interval between admission and diagnosis ranged from 24 hours to 6 days. Five children had associated traumatic pancreatitis. Initially, all the children were conservatively treated. In seven the hematoma resolved after 9–20 days. Two children were operated upon because the obstruction failed to resolve. All nine children recovered without permanent complications.

Conclusions: Intramural duodenal hematoma has many clinical and therapeutic puzzling aspects. Bicycle handlebar, road accidents and sports trauma are the main etiologic factors in children, but child abuse should be kept in mind. Associated traumatic pancreatitis is common. Gastroduodenal endoscopy may be useful to clarify doubtful cases. Pediatric surgeons should increase awareness regarding IDH in order to reduce delay in diagnosis and the need for surgical decompression.

Background: Food allergies in children are often very serious and can lead to anaphylactic reactions. Observations that camel milk ameliorates allergic reactions were noted over the years. The effect of the camel milk is probably related to its special composition.

Objectives: To investigate the effect of camel milk in several children with severe food (mainly milk) allergies.

Methods: We studied eight children with food allergies who did not benefit from conventional treatment. Their parents, or their physicians, decided to try camel milk as a last resort. The parents were advised by the authors – who have considerable experience with the use of camel milk – regarding how much and when the children should drink the milk. The parents reported daily on the progress of their children.

Results: All eight children in this study reacted well to the milk and recovered fully from their allergies.

Conclusions: These encouraging results should be validated by large-scale clinical trials.

Background: Since 1984, several waves of Ethiopian immigrants have settled in Israel. On arrival they were found to be highly infected with intestinal parasites and to have increased serum immunoglobulin E and eosinophilia. 

Objectives: To study serum IgE [1] levels in Ethiopian children growing up in the environment of Israel . 

Methods: We assessed four groups of children of Ethiopian origin: a) adolescents examined on their arrival to Israel (group 1, n=11); b) adolescents born in Ethiopia and living in Israel for more than 7 years (group 2, n=10); c) children of Ethiopian origin born in Israel, without a history of allergy or asthma (group 3, n=15); and d) asthmatic children of Ethiopian origin born in Israel (group 4, n=8). A thorough clinical interview and examination as well as serum IgE levels, stool parasites and absolute eosinophil count were performed. 

Results: Group 1 (11 newly arrived Ethiopian adolescents) had a mean eosinophil count of 688 cells/ml (0–1739) and a mean serum IgE of 1043 IU/ml (253–2932), P < 0.0009 as compared to group 2. Helminthic parasites were observed in 8/11 individuals; after 1 year of follow-up and anti-parasitic treatment, serum IgE levels did not change significantly. Group 2 (10 Ethiopian born adolescents living in Israel for on average 10 years, 7–15 years) had a normal leukocyte count, MEC [2] 192 cells/ml (range 54–289), serum IgE 142 IU/ml (range 14–399 IU/ml) and no parasites in stool. Group 3 (15 Ethiopian children born in Israel) had a normal leukocyte count, MEC 128 cells/ml (0–324), serum IgE 55 IU/ml (7–189 IU/ml), similar to age-matched Israeli controls. In group 4 (8 Israeli born children of Ethiopian descent diagnosed with asthma), serum IgE showed significant elevation compared to Israeli age-matched asthmatic children (P < 0.005).  

Conclusions: High levels of IgE found in Ethiopian children on arrival to Israel declined to Israeli control levels after several years of living in the new environment. Ethiopian children born in Israel had normal levels of IgE, suggesting that environment is the main factor affecting IgE levels in this population. Israeli born Ethiopian children with asthma had significantly increased serum IgE levels compared to asthmatics of Israeli origin. These findings suggest that both environmental and genetic factors determine the level of serum IgE in these children.

Objectives: To assess the achievements of participants in the PALS[1] course, as a cohort and by professional group, and their evaluations of different aspects of the course; and to describe the educational modifications introduced to the course since its introduction in Israel on the basis of our teaching experience.

Methods: The study sample consisted of physicians, nurses and paramedics from all areas of Israel who registered for PALS between January 2001 and December 2003. Participants took a standardized test before and after the course; a score of 80 or higher was considered a pass. On completion of the course, participants were requested to complete a 24-item questionnaire evaluating the quality of the course as a whole, as well as the lectures, skill stations, and instructors’ performance. Items were rated on a 5-point scale. Results were analyzed using the BMPD statistical package.

Results: Altogether, 739 subjects participated in 28 courses: 13 attending (in-hospital) physicians (1.8%), 89 community pediatricians (12%), 124 residents (16.8%), 304 nurses (41.1%), and 209 paramedics (28.3%). About half (48.9%) were hospital-based, and about half (47.9%) had no experience in emergency medicine. A passing grade was achieved by 89.4% of the participants; the mean grade for the whole sample was 87.2%. The mean test score of the residents was significantly better than that of the nurses (P < 0.05) and pediatricians (P < 0.01). The median evaluation score for four of the five stations was 5, and the mean overall score for all items was  4.56 (range by item 3.93–4.78).

Conclusions: PALS was successfully delivered to a large number of healthcare providers in various professional groups with very good overall achievements and high participant satisfaction. It significantly increased participants’ knowledge of pediatric resuscitation. We therefore recommend the PALS course as an educational tool in Israel.

Objectives: To determine whether children with multiple siblings are at increased risk for accidents, to assess whether quality of child supervision varies with family size, and to evaluate the relationship of family size with the rapidity of seeking medical care after an accident.

Methods: We prospectively studied 333 childhood accidents treated at TEREM (emergency care station) or Shaare Zedek Medical Center. Details on family composition and the accident were obtained through parental interview. Family size of the study population was compared with that of the Jerusalem population. Families with one to three children (Group 1) and four or more children (Group 2) were compared with regard to type of supervision and different "Gap times" – the time interval from when the accident occurred until medical assistance was sought ("Gap 1"), the time from that medical contact until arrival at Shaare Zedek ("Gap 2"), and the time from the accident until arrival at Shaare Zedek for those children for whom interim medical assistance either was ("Gap 3A") or was not ("Gap 3B") sought.

Results: Children from families with 1, 2, 3, 4 and ≥5 children comprised 7.2%, 18.3%, 14.4%, 18.6% and 41.4% of our sample compared to 20.4%, 21.8%, 18.4%, 14.7% and 24.7% in the general population respectively. Children from Group 2 were less often attended to by an adult (44.5% vs. 62.0%) and more often were in the presence only of other children at the time of the accident (27.0% vs. 10.5%). Gaps 1, 2 and 3A in Group 2 (6.3 hours, 16.5 hours, 27.8 hours respectively) were longer than for Group 1 (2.7, 10.7, 13.3 hours respectively).

Conclusions: The risk for accidents is increased among children from families with four or more children. The adequacy of child supervision in large families is impaired. There is a relative delay from the time of the accident until these children are brought for treatment. 

Objectives: To review the current status of MAS[1] in a pediatric tertiary care center in Israel, in terms of feasibility, safety, and effect on standard practices.

Methods: We reviewed the files of all children who underwent a MAS procedure in our department during the period April 2002 to July 2004, and compared the findings with those of children treated by standard practices.

Results: A total of 301 procedures were performed in 271 patients: 107 thoracoscopic and 194 laparoscopic. There were no major intraoperative complications. The total conversion rate was 3.65%: 0 for thoracoscopy and 5.6% for laparoscopy (11/194). Twenty-four types of procedures were performed during the study period. The thoracoscopies accounted for 92.24% of all thoracic procedures in the department (107/116), and routine abdominal laparoscopic procedures replaced open surgery in 30–100% of cases (total 44.8%, 194/433).

Conclusions: MAS procedures appear to be safe for a wide range of indications in children. In our center they currently account for a significant percentage of pediatric surgeries. We suggest that the integration of MAS training in the residency programs of pediatric surgeons be made a major long-term goal. The creation of a pediatric MAS study group, which would allow for multi-institutional studies, is especially important in Israel where a relatively large number of pediatric surgery departments handle a small annual number of patients.

Objectives: To compare the seasonality of children with T1DM in different populations around the world for which data were available.

Methods: We analyzed large cohorts of T1DM patients with a clinical disease onset before age 14 or 18 years.

Results: We found a seasonality pattern only in ethnically homogenous populations (such as Ashkenazi Jews, Israeli Arabs, individuals in Sardinia and Canterbury, New Zealand, and Afro-Americans) but not in heterogeneous populations (such as in Sydney, Pittsburgh and Denver).

Conclusions: Our findings attempt to explain the controversial data in the literature by showing that ethnically heterogeneous populations with a mixture of patients with various genetic backgrounds and environmental exposures mask the different seasonality pattern of month of birth that many children with diabetes present when compared to the general population.

Objective: To analyze the clinical features of cutaneous mastocytosis in a large series of children.

Methods: We conducted a file review of all children clinically diagnosed with cutaneous mastocytosis in our department over the last 20 years. We evaluated gender, age at onset, character and distribution of the lesions, associated symptoms, and course of the disease.

Results: Altogether, 180 patients with cutaneous mastocytosis were identified. The male to female ratio was 1.5:1. About one-third of patients had a mastocytoma, which was present at birth in over 40% and appeared during the first year of life in most of the remainder. Urticaria pigmentosa was noted in 65% of the patients, presenting at birth in 20% and during the first year in most of the remainder. The majority of lesions was distributed over the trunk and limbs. Different kinds of associated symptoms were noted. Prognosis, in general, was good. Only 11% of the cases, all urticaria pigmentosa, were familial.

Conclusions: Most cases of pediatric mastocytosis are sporadic and appear during the first 2 years of life, especially on the trunk. Urticaria pigmentosa is the most frequent variant. The prognosis of pediatric mastocytosis, in general, is good.
