Background: Over a 12 month period, the Israel Transplant Center doubled the number of donors by assigning a nurse coordinator to each of 22 hospitals around the country and by using kidneys from elderly donors.

Objective: To evaluate the impact of our "marginal donors" policy on the results immediately following transplantation.

Methods: Between October 1997 and September 1998, 140 cadaveric kidney transplantations from 72 donors were performed in Israel. We defined two groups of recipients: patients with immediate graft function and patients with either delayed graft function requiring >1 week of dialysis post-transplant or with primary graft non-function. We compared the following parameters between groups: donor and recipient age and gender, cause of donor’s death, length of stay in the intensive care unit, vasopressor dosage and creatinine levels before harvesting, cold ischemic time, and the number of recipient grafts.

Results: There were 102 recipients (72.8%) with immediate graft function and 38 with either PNF (n=13, 9.3%) or DGF (n=25, 17.9%). On regression analysis, donor age >50 year and retransplantation were significant risk factors for PNF or DGF (odds ratio 4.4 and 2.8, respectively). Of the 56 kidneys from donors >50 years old, 21 (37.5%) developed either PNF (n=9) or DGF (n=12).

Conclusions: We conclude that kidneys from donors over age 50 are at increased risk for graft non-function or delayed function. Better assessment of functional capacity of kidneys from “aged” donors may help to choose appropriate donors from that pool.

Background: Bronchiolitis caused by respiratory syncytial virus is one of the major causes of hospitalization in young children, especially during the winter.  Recent evidence has shown that pharmacological treatment, especially nebulized epinephrine, in addition to the traditional supportive treatment, can alleviate symptoms and shorten hospitalization, but this approach is not yet widespread.

Objectives: To determine whether the management of bronchiolitis in Israel is moving toward a stronger emphasis on pharmacological care.

Methods: A questionnaire on the diagnosis and management of bronchiolitis was completed by 27 heads of pediatric departments throughout Israel.  The questionnaire dealt with the frequency of usage of diagnostic and selected therapeutic procedures.

Results: Chest X-ray and arterial blood gases are commonly used as a diagnostic aid in more than 75% of the departments, and antibiotics are prescribed routinely in 24%.  Corticosteroids are still in use: 48% use systemic steroids, and 19% nebulized steroids.  Nebulized epinephrine is used in 22% of the departments, while nebulized beta-agonists are used frequently in two-thirds of the departments.

Conclusions: Despite convincing data that beta-agonists and steroids have no positive effect on the outcome of bronchiolitis on the one hand, and that nebulized epinephrine has advantages in children on the other, we found significant use of the former two agents and sparse use of the latter.  Greater awareness is needed among pediatricians, and measures should be introduced to incorporate the new recommendations, with further study of the effect of the old and new drugs on bronchiolitis.

 

Background: Recurrent abdominal pain is a common pediatric diagnostic problem.  Endoscopy is sometimes performed as part of the evaluation. Although gastritis and/or Helicobacter pylori infection is often present, it is not known if they contribute to the symptomatology.

Objectives: To evaluate the role of either gastritis or H. pylori infection in the symptomatology of children with RAP.

Patients and Methods: We retrospectively studied two groups of patients, 70 children in each, who had undergone endoscopy. One group was evaluated endoscopically for RAP and the other was a heterogeneous group that underwent endoscopy for indications other than RAP. Biopsies were taken during endoscopy and Giemsa staining was performed for the presence of H. pylori. Triple therapy was given as indicated, and the children were followed for an average of 6 months.

Results: Microscopic gastritis was diagnosed in 39 patients (55.7%) of the RAP group and in 31 of the heterogeneous group (44.2%) (NS), and H. pylori was found in 32 patients of the RAP group and in 16 of the heterogeneous group (45.7% vs. 22.8%, P<0.01). All children with H. pylori, except one in the heterogeneous group, had accompanying gastritis. On the other hand, gastritis without H. pylori infection was seen in 7 children in the RAP group and in 15 of the other. Endoscopy revealed macroscopic abnormalities in 52 of the 70 children with microscopic gastritis. There was a clinical improvement after triple therapy in 28 of 33 children with H. pylori-associated gastritis (84.85%), in 4 of 8 children with gastritis unassociated with H. pylori (50%), and in 8 of 15 without gastritis or H. pylori (53.3%) (P<0.01 between the H. pylori-associated gastritis and each of the other groups).

Conclusions: H. pylori infection and gastritis may be associated with RAP in a selected subgroup of children. We recommend a complete work-up, including endoscopy and invasive or non-invasive diagnostic modalities for H. pylori, and treatment of the infection.

Background: Acute respiratory distress syndrome is a well-recognized condition resulting in high permeability pulmonary edema associated with a high morbidity.

Objectives: To examine a 10 year experience of predisposing factors, describe the clinical course, and assess predictors of mortality in children with this syndrome.

Methods: The medical records of all admissions to the pediatric intensive care unit over a 10 year period were evaluated to identify children with ARDS¹. Patients were considered to have ARDS if they met all of the following criteria: acute onset of diffuse bilateral pulmonary infiltrates of non-cardiac origin and severe hypoxemia defined by <200 partial pressure of oxygen during ³6 cm H2O positive end-expiratory pressure for a minimum of 24 hours. The medical records were reviewed for demographic, clinical, and physiologic information including PaO2² /forced expiratory O2, alveolar–arterial O2 difference, and ventilation index.

Results: We identified 39 children with the adult respiratory distress syndrome. Mean age was 7.4 years (range 50 days to 16 years) and the male:female ratio was 24:15. Predisposing insults included sepsis, pneumonias, malignancy, major trauma, shock, aspiration, near drowning, burns, and envenomation. The mortality rate was 61.5%. Predictors of death included the PaO2/FIO2, ventilation index and A-aDO2³ on the second day after diagnosis. Non-survivors had significantly lower PaO2/FIO2 (116±12 vs. 175±8.3, P<0.001), and higher A-aDO2 (368±28.9 vs. 228.0±15.5, P<0.001) and ventilation index (43.3±2.9 vs. 53.1±18.0, P<0.001) than survivors.

Conclusions: Local mortality outcome for ARDS is comparable to those in tertiary referral institutions in the United States and Western Europe. The PaO2/FIO2, A-aDO2 and ventilation index are valuable for predicting outcome in ARDS by the second day of conventional therapy. The development of a local risk profile may allow early application of innovative therapies in this population.
