Gram-negative bacterial infections were documented in 6 neonatal New World camelids (5 Ilamas and 1 alpaca). The organisms isolated from blood before death or from multiple organs after death were Escherichia coli (n = 3), Actinobacillus sp (n = 1), and Klebsiella pneumoniae (n = 1). Only 2 crias survived, and 1 became blind secondary to retinal detachment and ocular inflammation, which developed after treatment for bacterial infection. Abnormal events during the perinatal period (prematurity, dystocia, cesarean section, weak at birth) were reported in all 6 crias. Signs of depression, convulsions, and/or coma were observed in all animals. Diarrhea and respiratory distress were also noticed in the 3 crias that died shortly after admission. Serum immunoglobulins were assessed, but without the benefit of a stall-side test specific for Ilama immunoglobulins. All crias were suspected to have poor transfer of maternal immunoglobulins. Hemograms and serum biochemical values prior to the initiation of treatment were obtained on 5 of the 6 crias. Total nucleated cells ranged from 1,400 to 23,100 cells/microliter. Four of the 5 crias has a left shift, and 2 crias had toxic neutrophils. Serum glucose concentrations, measured in 5 of 6 crias, ranged from 83 to 293 mg/dl. Serum creatinine values were high in 2 of 5 crias, 1 of which had acute tubular necrosis. Three crias with high serum electrolyte (sodium, chloride, or potassium) values subsequently died. Arterial blood gas values were assessed in 3 crias, 1 of which had respiratory alkalosis and mild hypoxemia.

Cattle in two herds developed signs of bloating, increased salivation and lacrimation, depression, respiratory distress, ataxia, and death after ingestion of hay that contained large amounts of poison hemlock (Conium maculatum). Twenty of 30 Angus cows and calves were affected in the first herd (2 died). In the second herd, 5 of 30 Holstein heifers were affected (1 died). The Conium alkaloids, coniine and gamma-coniceine, were quantified in the hay, the plants from the responsible hayfield, and the urine of affected animals.

Hyperbilirubinaemia in newborn infants is generally regarded as a problem, and bilirubin itself as toxic metabolic waste, but the high frequency in newborn infants suggests that the excess of neonatal bilirubin may have a positive function. To investigate the hypothesis that bilirubin has a role as a free-radical scavenger, the rate of rise in serum bilirubin in the first few days of life was measured in 44 infants with five illnesses thought to enhance free-radical production and in 58 control infants. The infants were selected from 2700 consecutive births by exclusion of those with factors known to affect bilirubin metabolism, including enteral feeding. The control infants were those who seemed to be ill and received treatment, including restriction of enteral feeds, but in whom no illness, or disorders not related to free-radical production, were found. The mean serum bilirubin rise was significantly lower in the combined illness group than in the control group (36.1 [95% Cl 26.9-45.3] vs 66.7 [55.9-77.5] mumol.l-1.day-1; p less than 0.0001). In subgroup analyses the mean rises in infants with circulatory failure, neonatal depression/asphyxia, aspiration syndromes, and proven sepsis were significantly lower than in controls matched for gestational age and birthweight, but rises in infants with respiratory distress and their matched controls did not differ. These findings are consistent with the hypothesis that bilirubin is consumed in vivo as an antioxidant. Such consumption may operate in vivo in addition to the standard pathways for bilirubin metabolism (production, isomerisation, and excretion).

Little is known of the endorphins' role in sepsis-induced respiratory distress and naloxone's effect as a treatment of it. Thirteen piglets were infused with live Escherichia coli at a rate of 2 to 10 x 10(8) colony-forming units per hour for six hours or until death and were divided into two groups: the septic control group (n = 8), and the naloxone-treated group (n = 5), which received 8 mg/kg/h of naloxone by continuous infusion. The results showed a significant reduction of QS/QT, VD/VT, and arterial carbon dioxide pressure at one hour and a significant increase of arterial carbon dioxide pressure and minute ventilation at 1, 3, and 4 hours in the naloxone-treated group, compared with the untreated septic group. None of the piglets in the naloxone-treated group developed ventilatory depression, while 75% of those in the untreated septic group did. Among the latter ficial effects of naloxone are likely related to its action on the central and peripheral respiratory regulatory mechanisms. A transient protection of the cardiac output and relatively decreased extravascular lung water with naloxone treatment may also, in part, improve the ventilation-perfusion maldistribution and secondarily reduce QS/QT and VD/VT.

The effect of an intravenous bolus injection of endotoxin, 0.1, 1 or 10 micrograms/kg, on rectal temperature, clinical appearance, haematological parameters, and on gastrointestinal electrical activity was examined in 11 conscious piglets of 4-5 weeks of age, with implanted electrodes in the antrum pylori, duodenum, jejunum and ileum. All doses resulted in a significant and dose-dependent increase in rectal temperature, in pronounced clinical signs and in distinct changes in haematological values. These included shivering, depression, respiratory distress, a leukopenia (0.1 micrograms/kg) or a leukocytosis (1 microgram/kg) with a shift to the left, an accelerated sedimentation rate and a decreased packed cell volume. Doses of 1 and 10 micrograms/kg induced a transient inhibition of gastroduodenal electrical activity. These results suggest that, in the piglet, endotoxin primarily manifests general clinical signs and that the gastrointestinal effects coincide with these.

Outpatient arthroscopic knee surgery carries with it certain risk factors similar to those accompanying other major knee procedures. These risks may be related to the complexity of the procedure, exposure to anesthesia, or risk factors from previous medical history. Two cases of acute pulmonary edema following arthroscopic knee surgery in otherwise healthy teenage athletes are presented. Both patients developed acute respiratory distress in the recovery room after uneventful arthroscopic knee surgery. The patients in both cases recovered and were able to return to sporting activity with no sequelae. The similarities in both cases prompted a retrospective investigation of the events from the induction of general anesthesia to the admission of the patients to the intensive care unit. Several possible causes of acute post-operative pulmonary edema include fluid overload, cardiac arrhythmia, respiratory depression, systemic drug reaction and sickle cell trait or disease. Outpatient arthroscopy still remains the procedure of choice for meniscal pathology of the knee, but the surgeon and the anesthesia personnel must be aware of and prepared for pulmonary complications that may arise in the immediate post-operative period.

A nephropathogenic Massachusetts strain of infectious bronchitis virus (IBV) designated H13-IBV was isolated from the kidneys of commercial broilers. H13-IBV caused respiratory distress, depression, and diarrhea in specific-pathogen-free chickens. Gross renal lesions included pale coloration, swelling, and urate deposition. Histologic renal changes were interstitial mononuclear cell infiltration and degeneration and necrosis of tubular epithelial cells. Lesions in respiratory tissues included thickening and edema of the air sacs, congestion of the tracheal mucosa, and frothy serous exudate. Histologic tracheal lesions were deciliation, mucous gland distortion, inflammatory cell infiltration, and squamous metaplasia. Clinically, H13-IBV was highly pathogenic in birds infected at 1 day of age and mildly pathogenic in birds infected at 4 weeks of age. Kidney lesions were of marked severity only in birds infected at 1 day of age. Tracheal lesions were similar in severity in both age groups.

Fibronectin is a large-molecular-weight glycoprotein present on most cell surfaces, in extracellular fluids, and in plasma. Both cell-associated and soluble fibronectin are thought to have important roles in the inflammatory response and host defense and may contribute to the maintenance of microvascular integrity during septic episodes. Newborn infants have levels of fibronectin in plasma that are one-third to one-half those found in the healthy adult. In addition, neonates with respiratory distress syndrome, perinatal asphyxia, bacterial sepsis, intrauterine growth retardation, or postnatal malnutrition have a further depression in their plasma levels of fibronectin. The low plasma concentration of fibronectin in newborn infants may contribute to the hypofunction of the neonatal reticuloendothelial system and predispose to the development of sepsis. Rates of synthesis of plasma fibronectin are diminished in the neonate, and an inverse correlation between fibronectin half-life and gestational age exists. The role of fibronectin in treatment or prophylaxis of neonatal sepsis remains to be determined.

Although chloral hydrate sedation has been proposed as an alternative to evaluation under anesthesia for pediatric patients who are unable to cooperate with routine test procedures, a careful study of the drug's safety and effectiveness is lacking. This study reports the effectiveness and safety of high-dose chloral hydrate for ophthalmic examination in 302 patients between the ages of 1 month and 5 years. The patients had nothing to eat or drink for 4 hours prior to drug administration. The patients were monitored during sedation and until fully awake. Eighty-eight percent of the patients (266/302) were successfully sedated without a supplemental dose. There were no reports of any complications including emesis, respiratory distress or depression, behavioral problems, changes in vital signs, patient injury, or hospital admission. The high-dose chloral hydrate protocol described, results in safe and generally successful sedation of pediatric patients for ophthalmic examination.

A nephropathogenic Massachusetts strain of infectious bronchitis virus, designated H13-IB virus, was isolated from the kidneys of broilers in a commercial flock. Respiratory distress, diarrhea, depression, and high mortality were present. Gross renal lesions consisted of pale coloration, mottling, urate deposition, and swelling. The trachea contained a serous to catarrhal exudate. Microscopically, renal changes were primarily associated with the medullary region. Lesions included an interstitial mononuclear cell infiltration, urate deposition, edema, and degenerative and necrotic tubular changes. Tracheal changes included marked thickening of the mucosa, desquamation of ciliated and glandular epithelia and replacement with a stratified undifferentiated epithelium, and inflammatory cell infiltration.
