Acute and progressive respiratory distress ("shock lung") is a well known and feared complication in human patients with a variety of underlying disorders, even though the lungs are not involved primarily. In spite of the fact that dogs, and other animals, very often have been used in experimental models studying this syndrome, "shock lungs" have not received much attention in veterinary medicine. With the improved and more intensive treatment of severely diseased animals during the last years, especially pet animals, it is reasonable to assume that the lungs will be more important as an end organ also in veterinary practice. Animals in shock, particularly if complicated with sepsis, are prone to develop progressive respiratory distress. This paper reviews the current knowledge about the clinical picture, pathology and pathogenesis of acute respiratory disease, with main emphasize on the pathogenetic mechanism.

Sixty-six patients more than 30 days and less thant 16 years of age suffering an unexpected cardiac arrest in an 18-month period were included in a study of resuscitative measures in children. Six children survived to be discharged from hospital. Respiratory disease accounted for most (29%) of the cardiac arrests, but it also had the most favourable prognosis, 21% of the 19 patients surviving. None of the patients survived whose cardiac arrest was secondary to sepsis or trauma, even when the resuscitative efforts were initially successful. Only 1 of the 41 patients who had a cardiac arrest outside of hospital survived, and only 1 of the 34 patients who presented with asystole survived, and then with considerable damage to the central nervous system. The interval between cardiac arrest and application of basic life support was substantially shorter among the survivors. Also, most of the survivors did not present with asystole. The results of this study suggest that survival among resuscitated children is no better than that among adults but can be improved with early recognition and monitoring of children at risk. earlier application of basic and advanced life support, improved education of medical and lay personnel, and further research into pediatric resuscitative techniques.

To investigate the importance of transfusion practice with packed red cells (PRCs) in premature infants and to identify risk factors significant influencing transfusion practice, we analyzed 75 preterm infants (gestational age: 31 +/- 2 weeks; birth weight: 1459 +/- 402 g) admitted to the neonatal intensive care unit of Catholic University of Rome. Fifty-three (70.7%) of the infants received one or more PRCs transfusions (in total 246 transfusions). The variables associated with an increase in number and frequency of PRCs transfusions were: a) gestational age < or = 30 weeks; b) birth weight < or = 1000 g; c) severe neonatal pathology (ie a respiratory disease requiring ventilatory support and/or a clearly documented or suspected sepsis). Repeated PRCs transfusions during the first week of life significantly (p < 0.01) influenced the need for late transfusions, after 4 weeks of age, for the treatment of the anemia of prematurity. These data indicate that preterm infants with a gestational age < or = 30 weeks, a birth weight < 1000 g and a severe respiratory or infectious disease represent natural candidates for administration of recombinant human erythropoietin to reduce the need for late PRCs transfusions.

A prospective study was conducted to describe the causes of and farm management factors associated with disease and death in a population of foals in Texas. Data from 2,468 foals at 167 farms were provided by veterinarians for all 12 months during 1991. Among 2,468 foals, 116 deaths were reported (4.7%). Pneumonia was the most commonly reported cause of death, followed by septicemia. When considered as a group, musculoskeletal disorders (traumatic, infectious, or deforming problems) represented the most common cause of all reported deaths. Daily risk of death was greatest during the first 7 days of life, and decreased with age. Risk and frequency of causes of death varied by age. Crude incident morbidity during the year was 27.4% (677/2,468). Respiratory disease was the most common cause of incident disease in the study population, followed by diarrhea. Risk of disease was greatest among < or = 7 days old, and decreased with age. Crude rate of incident of diarrhea was significantly lower among farms where foals were born on pasture, compared with that at farms where foals were born in stalls. The practice of assessing passive immunity was significantly associated with decreased morbidity from septicemia and pneumonia.

A physician's assessment of the probable outcome of an episode of respiratory failure should be based on a combination of survival data from large studies and specific knowledge about the individual case in question. Clearly, mortality rates in cases of ARF are influenced by a number of factors. In general, only a minority of patients with ARF complicating COPD require mechanical ventilation. In these cases, mortality often is related to the nature of the precipitating illness and the severity of the patient's underlying chronic respiratory disease. The long-term prognosis in patients with COPD who survive an episode of ARF is related primarily to the severity of the patient's underlying disease. Acute mortality is higher in patients with ARDS than in patients with ARF complicating COPD. Although a significant number of ARDS patients die of their underlying illness, mortality in others more commonly appears to be related to sepsis and multiple organ failure rather than end-stage respiratory disease. Pulmonary function in survivors of ARDS is quite variable, and may be related to the severity of the acute episode. ARF has a particularly poor prognosis when associated with certain underlying illnesses such as hematologic malignancy.

Two thousand eight hundred ninety-eight children younger than 5 years old were investigated during a 2-year period in a rural area of The Gambia for possible pneumonia, meningitis or septicemia. After clinical examination and appropriate investigations, 1014 children were diagnosed as having pneumonia, 31 as having meningitis and 100 as having septicemia. Nine hundred seven children had a final diagnosis of malaria including 702 who satisfied the World Health Organization criteria for a diagnosis of pneumonia. A bacterial etiology was established in 115 (11%) patients with a final diagnosis of pneumonia, in 25 (81%) with meningitis and in 29 (29%) with suspected septicemia. Overall the pneumococcus was the leading pathogen identified among children with pneumonia and meningitis and ranked third among those with septicemia. However, during the wet season, when malaria transmission was highest, 50% of blood culture isolates obtained from children satisfying the World Health Organization criteria for a diagnosis of pneumonia were Salmonella or coliform species, and the pneumococcus and Haemophilus influenzae type b accounted for only 43% of isolates. Thus enteric bacteria may be as important as those bacteria more usually associated with respiratory disease among children presenting with a clinical picture of pneumonia during the wet season. This finding has important implications for case management and surveillance for antibiotic resistance.

A prospective cohort study was undertaken to determine calf-level factors that affect performance (growth) between birth and 14 months of age in a convenience sample of approximately 3300 female Holstein calves born in 1991 on two large Florida dairy farms. Data collected on each calf at birth included farm of origin, birth date, weight, height at the pelvis, and serum total protein (a measure of colostral immunoglobulin absorption). Birth season was dichotomized into summer and winter using meteorological data collected by University of Florida Agricultural Research Stations. Data collected at approximately 6 and 14 months of age included age, weight, height at the pelvis, and height at the withers. Growth in weight and stature (height) was calculated for each growth period; growth period 1 (GP1) = birth to 6 months, and growth period 2 (GP2) = 6 to 14 months. Health data collected included data of initial treatment and number of treatments for the diseases diarrhea, omphalitis, septicemia, pneumonia and keratoconjunctivitis. After adjusting for disease occurrence, passive transfer of colostral immunoglobulins had no significant effect on body weight gain or pelvic height growth. Season of birth and occurrence of diarrhea, septicemia and respiratory disease were significant variables decreasing heifer growth (height and weight) in GP1. These variables plus farm, birth weight and exact age when '6 month' data were collected explained 20% and 31% of the variation in body weight gain and pelvic height growth, respectively, in GP1. The number of days treated for pneumonia before 6 months of age significantly decreased average daily weight gain in GP2 (P < 0.025), but did not affect stature growth. Treatment for pneumonia after 6 months of age did not significantly affect weight or height gain after age 6 months. Neither omphalitis nor keratoconjunctivitis explained variability in growth in either of the growth periods.

Following its introduction into the market, PAPM/BP (panipenem/betamipron) was clinically studied in 188 evaluable cases out of 207 cases primarily of respiratory infectious diseases treated at the pediatric departments of 15 hospitals. In the clinical evaluation, the drug proved effective in three of three cases of sepsis; three of three cases of suppurative meningitis; nine of ten cases of laryngopharyngitis, six of seven cases of tonsillitis, 56 of 63 cases of acute bronchitis, 90 of 98 cases of pneumonia, and one of one case of phyothorax, all of which are respiratory infectious diseases; one of one case of secondary infection of a chronic respiratory disease; and two of two cases of lymphadenitis, which is a disease of the soft dermal structure. The overall efficacy rate was 91.0% (171/188 cases). In the bacteriological study, Gram-positive bacteria were eliminated in five of five strains of S. aureus, 30 of 31 strains of S. pneumoniae (96.8%), and three of three strains of S. pyogenes. Gramnegative bacteria were eliminated in 15 of 17 strains of H. influenzae (88.2%), three of four strains of M. catarrhalis, and two of two strains of K. pneumoniae. The overall elimination rate was 92.1% (70/76 strains). In the 23 strains of S. pneumoniae that were examined, penicillin-resistant strains accounted for 56.5%, showing an elimination rate of 100%. No serious adverse effects were observed, and the incidence of adverse effects was 1.45%. As for abnormalities in laboratory tests, levels of GOT and GPT increased in eight cases (3.88%), LDH increased in one case (0.48%), and neutropenia occurred in one case (0.51%). These results suggest that PAMP/BP could be considered the first choice in the treatment of infectious diseases in pediatrics, due to its effectiveness and high level of safety.

Tracheoesophageal fistula is a complication of endotracheal canulas with pressure balloon during mechanical ventilation, for which treatment is surgical closure. There are approximately 80 reported cases in the world literature. Here we report our experience at the National Institute of Respiratory Diseases of Mexico. We performed surgical treatment of 7 patients (4 males, 3 females, 17 to 65 years of age) with tracheoesophageal fistula from 1991 to 1995, referred from other hospitals. Six had a history of prolonged orotracheal intubation, and the seventh had a traumatic lesion of the neck. Preoperatory management varied from 1 to 8 weeks, with treatment of malnutrition and infections. Esophagus was sutured with polyglactin 000 in two layers, the inner with interrupted, and the superficial with continuous sutures. The area was covered with a muscle strap. In six patients, simple suture of trachea was performed. In the seventh, due to an extensive tracheal defect, we decided to use a second muscle strap to occlude it. Six patients have had a follow up of 15 months to 5 years with satisfactory evolution. One patient died due to abdominal sepsis. We conclude that this technique provides a good prognosis for this disorder.

Non-cardiogenic pulmonary oedema, an early manifestation of the adult respiratory disease syndrome, is a serious complication following major vascular surgery. Hypovolaemia, ischaemia-reperfusion injury, massive blood transfusion, transient sepsis and transient endotoxaemia are insults responsible for initiating the process in vascular surgical patients. Free radicals, cytokines and humoral factors released secondary to the above insults activate neutrophils and facilitate their interaction with the endothelium. Activated neutrophils marginate through the endothelium where they are responsible for tissue injury by the release of free-radicals and proteases. The lungs are a large reservoir of neutrophils and bear a significant part of the injury. Conventional therapy includes treating the underlying condition and providing respiratory support. A better understanding of the pathophysiology of this process has led to new experimental treatment options. Novel therapeutic interventions have included the use of compounds to scavenge free radicals, anti-cytokine antibodies, extracorporeal lung support, nitric oxide and artificial surfactant therapy. The multifactorial nature of this process makes it unlikely that a single "magic bullet" will solve this problem. It is more likely that a combination of preventative, prophylactic and therapeutic modalities may reduce the mortality of this condition.
