    Notes: Abstract Two children, aged 3 1/2 and 5 1/2 years, are described. Both developed pulmonary oedema (PE) following a short episode of choking on a sweet and an orange, respectively. On admission diagnosis was made by chest X-ray. One child was asymptomatic despite PE while the other showed only mild respiratory distress. Both children recovered spontaneously and chest X-rays showed a return to normal within 24 h. The mechanism of PE production is discussed. It is suggested that oedema formation occurs during the obstruction and that it is due to hypoxia and the severe negative pleural pressure resulting from attempts to inspire against the obstructed airway. both hypoxia and severe negative pleural pressure cause an increase in pulmonary capillary pressure and transduration of fluid across the capillary membrane.

    Notes: Abstract Microorganisms from activated sludge were immobilized on a spiral reactor fabricated from a PVC-Silica based biosupport, and used to biosorb lead from synthetic waste streams. Biosorption parameters determined for lead from Freundlich isotherms indicate that 89% of the binding capacity of that observed in suspended cell system is retained in the spiral bioreactor. More than 87% of biosorbed lead was recovered each time after breakthrough by dilute acid washing between the pH of 2 to 2.5. No significant changes in the biosorption pattern was observed over several adsorption and recovery cycles that were conducted. The spiral bioreactor is better than suspended cell systems because it provides comparable surface area as that in the suspended cell system in an immobilized (small volume) form. It is also better than the entrapped microbial cell reactors because it eliminates mass transfer resistance across the external matrix, which may reduce the inherent binding capacity.

    Notes: Abstract Objective: To determine short- and long-term outcomes of infants with severe hypothermia (≤ 28 °C) treated in a pediatric intensive care unit (PICU).¶Design: (1) Retrospective evaluation of medical records of all patients admitted for severe infantile hypothermia from 1984 to 1993. (2) Medical and developmental evaluations of survivors of severe infantile hypothermia 3–12 years after hospital discharge.¶Setting: Six-bed PICU of a university teaching hospital.¶Patients: Eighteen infants who arrived at the emergency room with a rectal temperature between 20 and 28 °C.¶Measurements and results: The ages of patients ranged between 5 and 30 days. Fifteen were Bedouins and three were Jews. Clinical features included sepsis in 9 (septic shock in 5 of 9) patients, respiratory failure in 11 and overt bleeding in 5. Rewarming was applied using rapid external warming under a radiant heater. Five infants died shortly after arrival and one patient at age 6 years; all of them had sepsis on arrival. Of the 12 survivors examined at ages 3–12 years, ten had normal psychomotor achievements, while the remaining two had mild (1 patient) and severe (1 patient) psychomotor retardation. Both of the latter two had sepsis on first admission for hypothermia. All nine hypothermic infants, who had no sepsis, had normal medical examinations and normal developmental achievements for their ages.¶Conclusion: Severe infantile hypothermia is a serious condition. When treating patients in a modern PICU, morbidity and mortality are mainly related to the presence or absence of an associated septicemia. Infants without septicemia may have normal growth and development.

    Notes: Abstract A 22-month-old girl with the syndrome of hypoventilation, pulmonary hypertension, cor pulmonale and pulmonary edema due to adenoidal hypertrophy is described. Adenoidectomy resulted in relief of all symptoms and signs within 24 h. Hemodynamic study using pulmonary artery catheter showed that the pulmonary artery pressure returned to normal 48 h after relief of the obstruction. The normal left ventricular end-diastolic pressure, measured throughout the period of obstruction, in the presence of severe pulmonary edema, could suggest a non-cardiogenic “low pressure” pulmonary edema. However, the highly negative pleural pressure which existed during upper airway obstruction indicated an elevation of transmural left ventricular end diastolic pressure (compared to pulmonary wedge pressure) and thus, suggested that the pulmonary edema in this syndrome is secondary to both — right and left heart failure.

    Notes: Abstract A comparative study between two reactors, one using microorganisms entrapped in calcium alginate gel, and the other using microorganisms attached on the surface of a membrane (polymeric microporous sheeting, MPSTM) to biodegrade phenol is performed. Results indicate that the alginate bead bioreactor is efficient at higher phenol concentrations while the membrane bioreactor shows better performance at lower phenol concentrations. This unique response is primarily attributed to the different techniques by which the microorganisms are immobilized in the two reactors. In batch mode, below a starting concentration of 100 ppm phenol, biodegradation rates in the membrane bioreactor are (7.58 to 12.02 mg phenol/h · g dry biomass) atleast 10 times the rates in alginate bead bioreactor (0.74 to 1.32 mg phenol/h · g dry biomass). Biodegradation rates for the two reactors match at a starting concentration of 250 ppm phenol. Above 500 ppm phenol, the rates in the alginate bead bioreactor are (7.3 to 8.1 mg phenol/h · g dry biomass) on an average 5.5 times the corresponding rates in the membrane bioreactor (2.18 to 1.03 mg phenol/h · g dry biomass). In continuous feed mode the steady state degradation rates in the membrane bioreactor are one to two orders of magnitude higher than the alginate bead bioreactor below 150 ppm inlet phenol concentration. At an inlet concentration around 250 ppm phenol the rates are comparable. Above 500 ppm of phenol the rates in the alginate bioreactor are an order of magnitude high than the membrane bioreactor. Due to substrate inhibition, and its inability to sustain a high biomass concentration, the membrane bioreactor shows poor efficiencies at phenol concentrations above 250 ppm. At low phenol concentrations the apparent reaction rates in the alginate bead bioreactor decrease due to the diffusional resistance of the gel matrix, while biodegradation rates in the membrane bioreactor remain high due to essentially no external diffusional resistance. Results indicate that a combined reactor system can be more effective for bioremediation than either separate or attached microbial reactors.

    Description / Table of Contents: Zusammenfassung Bei zehn von 710 Patienten (1,4%), die wegen Croup in den Jahren 1983 bis 1989 in das Soroka Medical Center eingewiesen worden waren, traten schwere bakterielle Infektionen auf. 64 Patienten (9% aller Croup-Patienten) wurden in die pädiatrische Intensivstation aufgenommen, 13 (20%) mußten beatmet werden. Bei neun der 13 intubierten Patienten traten bakterielle Infektionen auf. Bei den anderen 51 in der pädiatrischen Intensivstation behandelten Patienten, die nicht intubiert werden mußten, kam es in keinem Fall zu einer bakteriellen Infektion und nur in einem der 646 Fälle (0,2%), bei denen eine Intensivbehandlung nicht nötig war (p〈0,0001). Zwischen den beiden auf der pädiatrischen Intensivstation behandelten Patientengruppen bestand kein Unterschied hinsichtlich Alter, ethnischer Herkunft oder Körpertemperatur bei Aufnahme. Die kausalen Infektionserreger wurden in drei Fällen aus Blut und in acht Fällen aus eitrigem Trachealsekret isoliert. Bei allen auf der pädiatrischen Intensivstation beatmeten, intubierten Patienten lag eine schwere Erkrankung vor: acht hatten eine bakterielle Tracheitis und einer eine Supraglottitis. Wegen der großen Menge an eitrigem Sekret mußte bei den Patienten mit bakterieller Tracheitis häufig eine Trachealabsaugung vorgenommen werden. Der eine Patient, der nicht intensivmedizinisch behandelt wurde, hatte eine vorübergehende Bakteriämie entwickelt. Wir gehen davon aus, daß die Notwendigkeit der Intubation bei den Croup-Patienten ein Indikator für eine bereits bestehende schwere bakterielle Infektion war.
    Notes: Summary Serious bacterial infections occurred in ten children (1.4%) of 710 patients with croup admitted to the Soroka Medical Center during the years 1983–1989. Sixty-four patients (9% of all croup patients) were admitted to the pediatric intensive care unit (PICU), and 13 of them (20%) required intubation. Bacterial infections were noted in nine of the 13 intubated patients, in none of the other 51 PICU patients who did not require intubation and in one of the 646 patients (0.2%) who were not admitted to the PICU (p〈0.0001). There was no difference in age, ethnic origin, or body temperature on arrival between the two PICU groups. Causative microorganisms were isolated from blood samples (three cases) and tracheal pus (eight cases). All intubated PICU patients were seriously ill: eight had bacterial tracheitis and one supraglottitis. Patients with bacterial tracheitis required frequent suctioning of the trachea for copious purulent secretions. The single patient with bacterial infection who was not admitted to the PICU had transient bacteremia. We conclude that the need for intubation in croup patients was an indicator for the presence of a serious bacterial infection.
