The effects of gender on mortality and morbidity of all neonates weighing less than 1500 g admitted to King's College Hospital Neonatal Intensive Care Unit during 1980-82 (n = 271) were examined. Very low birthweight boys had a significantly higher mortality and more postnatal complications than girls. The higher incidence of respiratory distress syndrome and pulmonary interstitial emphysema in boys was associated with increased mortality in the first year. Surviving boys had significantly more problems, including lower Apgar scores at five minutes, more frequent apnoeic attacks and bradycardic episodes, transient tachypnoea, neonatal anaemia, and lower blood calcium and phosphate concentrations. Surviving children were followed up at 1 and 2 years of age. Development of boys at 1 year was significantly delayed compared with girls in all fields save locomotor. Although at 2 years some of the differences had diminished, those in language and personal social skills were more pronounced. More than twice as many boys as girls had major neurodevelopmental disorders.

Neisseria microorganisms (Neisseria lactamica, Neisseria sicca, and Neisseria mucosa) are regarded as normal respiratory commensals. Branhamella catarrhalis (formerly Neisseria catarrhalis) has also been regarded as a normal respiratory commensal, but reports indicate that it can be pathogenic. The role of Neisseria spp was studied in 160 patients with chest infections and symptoms and signs of obstructive respiratory disease. Group I patients (n = 140) had a history of asthma, bronchitis, and emphysema. Group II patients (n = 20) had an initially responsive pulmonary tuberculosis but presented with fever and obstructive airway disease. Group I patients had disease that was difficult to control despite increased bronchodilator therapy, but they responded dramatically after two to three days of appropriate antibiotic therapy. Patients in group II showed a similar response to erythromycin. Neisseria infection was responsible for precipitating or exacerbating respiratory distress in both groups. Accordingly, it is concluded that Neisseria can be pathogenic and that patients with fever and obstructive respiratory symptoms require treatment.

Interstitial pneumonias comprise a significant proportion of cattle respiratory diseases. Known by different names, such as acute bovine pulmonary emphysema and edema (ABPE), fog fever, atypical interstitial pneumonia (AIP) and cow asthma, the condition seems to occur predominantly in late summer or fall. However, depending on the etiology, cases have occurred throughout the year. Interstitial pneumonia often begins with acute respiratory distress in animals that were clinically normal 12 hr earlier. Animals are observed breathing very rapid and shallow with their mouths open. If disturbed, death may occur rapidly from hypoxia. Causes of interstitial pneumonia are quite varied ranging from parasitic, viral and bacterial to toxic. Toxic agents constitute the most economically important cause of this condition in cattle. The primary toxin is the amino acid L-tryptophan in lush pasture grasses, a compound which is converted to 3-methylindole by rumen microorganisms. Other leading toxic causes of interstitial pneumonia are perilla mint and moldy sweet potatoes. Although treatments are mainly symptomatic and ineffective, preventive measures will reduce the occurrence of interstitial pneumonia. Prevention consists of denying animals exposure to know pneumotoxic agents, eliminating certain rumen microflora that break down the toxic compounds to reactive metabolites, and supplying ample good forage so that cattle will not as likely consume toxic plants.

Compressed air injuries to the esophagus are uncommon. They characteristically present with respiratory distress, subcutaneous and mediastinal emphysema, and may have a pneumothorax. The distal esophagus is always the site of rupture and requires prompt surgical repair to avoid serious morbidity and potential lethal complications.

Pulmonary cystic lesions presenting in the neonatal period can be congenital in origin, such as cystic adenomatoid malformation and congenital lobar emphysema, or they can be acquired. With recent advances in the support of premature infants with respiratory distress syndrome (RDS), acquired cystic lesions such as pulmonary interstitial emphysema (PIE), lobar emphysema, and parenchymal cysts have become more common. Several treatments have been proposed for these acquired lesions. We report what we believe to be the first case in which unilateral high-frequency ventilation (HFV) combined with low-rate intermittent mandatory ventilation (IMV) has been used to successfully manage an acquired lung cyst in a newborn.

Bovine ephemeral fever (BEF) was diagnosed on several commercial farms around Harare, Zimbabwe. The affected animals showed signs of fever (40-41.5 degrees C), depression, ruminal stasis, lameness and recumbency. Eight of those attended had severe respiratory distress and subcutaneous emphysema. Haematological and biochemical results indicated leukocytosis with an attending lymphopaenia. Selenium deficiency was detected only in those animals which showed respiratory embarrassment and subcutaneous emphysema.

Three cases of respiratory distress with patent ductus arteriosus are presented. The left-to-right shunt across the ductus arteriosus produced dilated pulmonary arteries and secondary bronchial compression, leading to lobar emphysema. The increase of blood flow across the ductus arteriosus causes structural changes of the wall of the preacinar and intra-acinar arteries. All three patients died, most probably from the association of parenchymatous pulmonary disease and pulmonary obstructive vascular disease.

The patient was a 63-days-old boy who was admitted to our hospital because of moderate cyanosis and tachypnea. After admission, severe respiratory distress and emphysematous change of the right lung on the chest X-ray developed progressively. Echocardiogram and angiocardiogram demonstrated that a tetralogy of Fallot associated with right aortic arch and absence of pulmonary valve, and revealed remarkably dilated ascending aorta which compressed the right pulmonary artery and bronchus. Therefore, the emergency operation in that the ascending aorta was suspended to the 2nd rib was performed through a right thoracotomy. After surgery, his respiratory distress and emphysema of the right lung completely disappeared. To our knowledge, this is the 2nd reported case in which suspension of ascending aorta was successfully performed for pulmonary complication in congenital cardiovascular anomalies as this patient.

A protein free artificial surfactant (artificial lung expanding compound; ALEC) composed of dipalmitoylphosphatidylcholine and phosphatidylglycerol was assessed for its effect on the main complications of prematurity in a prospective two stage randomised trial of 328 unselected babies delivered at between 25 and 29 weeks of gestation. Babies were randomised to receive approximately 100 mg artificial surfactant suspension or 1 ml saline. This was given at birth into the pharynx with up to three more endotracheal doses if the baby was intubated during the first day. Treatment with artificial surfactant reduced the neonatal mortality from 27% to 14%, the incidence of parenchymal brain haemorrhages from 24% to 16%, and the severity of the respiratory distress syndrome. In the first 10 days babies treated with artificial surfactant who survived averaged 19 hours less in greater than 30% oxygen, 20 hours less ventilation, and 17 hours less supplemental oxygen. Artificial surfactant had no effect on the incidence of pneumothoraces, pulmonary interstitial emphysema, patent ductus arteriosus, or postnatal infections and no serious side effects. Artificial surfactant (ALEC) given to very premature babies at birth significantly reduces their mortality and the respiratory support needed and should prove a valuable addition to treatment.

In a randomized multicenter trial, involving the collaboration of eight European neonatal intensive care units, the efficacy of replacement therapy with a new surfactant preparation (Curosurf) was tested in 146 patients with severe neonatal respiratory distress syndrome. Criteria for entry included birth weight 700 to 2,000 g, age when treated two to 15 hours, and requirement of artificial ventilation with FiO2 greater than or equal to 0.6. The babies were treated with a single large dose of surfactant (200 mg/kg) at a median age of nine hours (range two to 15 hours). Average FiO2 before treatment was the same (0.80) for both surfactant-treated patients and control patients. Babies receiving surfactant showed, within five minutes, a dramatic improvement of oxygenation as reflected by a nearly threefold increase of the PaO2/FiO2 ratio. Six hours after randomization, the PaO2/FiO2 ratio still showed a 98% improvement in surfactant-treated patients compared with controls (P less than .001), and statistically significant differences in favor of the treated babies persisted until 48 hours after randomization, when surviving control infants began to recover. Treatment with surfactant decreased neonatal (less than or equal to 28 days) mortality from 51% to 31% (P less than .05). Compared with control babies, the surfactant-treated group also had a decreased incidence of pulmonary interstitial emphysema (23% v 39%; P less than .05) and pneumothorax (18% v 35%; P less than .05). The percentage of survivors without bronchopulmonary dysplasia in the treated group was more than twice that of the control group (55% v 26%; P less than .001).(ABSTRACT TRUNCATED AT 250 WORDS)
