75 out of 77 children surviving IRDS with the aid of intermittent positive pressure ventilation have been followed up by age 2.6-7.6 years together with 68 matched controls. The morbidity of lower respiratory tract illnesses was significantly higher in IRDS survivors than in controls affecting a total of 48%, half whom were admitted to hospital on at least on occasion. Only 3 IRDS survivors had pneumonias beyound their third year, however. One child suffered from a moderate stridor due to a partial laryngeal stenosis and one from some dyspnoea at function caused by broncho-pulmonary dysplasia. Thoracic X-ray changes were found significantly more often and more marked in IRDS survivors but on the whole the changes were discrete. Neither the occurrence of pneumonia nor X-ray changes in the IRDS survivors were statistically relatable to a number of neonatal or therapeutical characteristics. Measurements of heart volume, respiratory frequency, oxygen saturation and acid-base values did not differ between the groups. Ventilated IRDS survivors, even with some degree of radiographic demonstrable residua, thus seem to have a good long-term prognosis with regard to lung function, irrespective of a preliminary high morbidity of lower respiratory tract illnesses.

The 5-year outcome of 101 extremely low birthweight (ELBW, < 1000 g) children discharged from the Neonatal Intensive Care Unit was reported. Over this period, there were four post-discharge deaths. The neurodevelopmental impairment rate was 18% overall: cerebral palsy 7%, blindness 3%, deafness 3% and developmental delay 10%. Seventy-one percent of children were readmitted to hospital. The mean number of admissions was 2.4 per child and the mean duration of total hospital stay was 11.3 days per child in the 5-year period. A trend was observed in a reduction in the readmission rate and hospital days in the 2-5-year period compared to the period between discharge and 2 years, though the differences were not statistically significant. The most common reason for readmission was for surgical procedures, primarily aural ventilation tube insertion and tonsillectomy and adenoidectomy. Significant health problems included recurrent wheezing episodes, stridor and croup in the period up to 2 years and otitis media and tonsillitis between 2 and 5 years. There was some catch-up growth, especially in height, between 2 and 5 years. Children with < 800 g birthweight had similar rates of neurodevelopmental impairment and hospital readmission to those of 800-999 g birthweight. However, they experienced more otitis media and pneumonia, had more ear, nose and throat operations, and at 5 years of age, more were below the 3rd centile for weight. This study showed that the health status of ELBW children had improved between 2 and 5 years, but they continued to experience recurrent health problems and hospital readmissions which would have resulted in added financial and emotional burdens to their families.

In July-August 1989, 2 primary health care (PHC) workers (nurses and nurse's assistants) and a pediatrician used WHO case management protocol to assess the conditions of 362 2-59 month old children who came to Mbabane Government Hospital and the Salvation Army Clinic in Mbabane, Swaziland, with coughing (99%) and difficulty in breathing (29%). The PHC workers had earlier undergone a 5-day training period on identifying signs and symptoms of pneumonia. A consulting pediatrician and a public health official conducted this study to compare the ability of the PHC workers to recognize the clinical signs of pneumonia with that of the pediatrician (gold standard). 64% of the children had a history of fever, but only 12% had a fever (38.3 degrees Celsius) at admission. 4 children had had convulsions. The PHC workers did not do well at recognizing the danger signs of stridor and abnormal sleepiness (sensitivity 50% and 0-14%, respectively). They were able to correctly recognize the danger sign of severe undernutrition in 2 children, however. They correctly identified most children with true fever (sensitivity 73-76%), yet they also claimed that many children with normal temperature had a fever (specificity 62-78%). Thus they would have administered antipyretics to 2-3 times too many children. The nursing assistants detected audible wheeze in only 4 of 14 children with audible wheeze (sensitivity 29%), while the nurses only detected 2 such children (sensitivity 14%). Further, they diagnosed audible wheeze in 18 children who actually had blocked nostrils. They correctly identified fast breathing in almost 75% of cases. Nurses were more likely to correctly diagnose chest wall indrawing than the nursing assistants (sensitivity 68% vs. 34%; p = .0048). Overall, the training helped the PHC workers to diagnose pneumonia quit well (sensitivity 71-83%, specificity 84-85%). Future training programs must focus on recognition of 2 danger signs, stridor and abnormal sleepiness, however.

A seven-month-old baby with double aortic arch was reported. He was admitted to our hospital with complaint of frequent respiratory infections shortly after birth. On examination, bronchofiberscopy revealed compression of the trachea and left main bronchus from behind and angiography showed complete vascular ring, namely double aortic arch with no other cardiac anomaly. Soon after the operation, stridor disappeared at rest, but mild stridor persisted on exertion. Three months later, he was re-admitted to our hospital because of pneumonia. Therefore, close observation is required for the patients with double aortic arch, even if the operation is effective.

Clinical and chest radiographic findings were recorded prospectively in 185 children with cough who attended an outpatient clinic in Papua New Guinea. Children were studied if they were between 8 weeks and 6 years of age; patients with wheeze, stridor, measles, or pertussis were excluded. 56 children (30%) had radiological evidence of pneumonia. The presence of either a respiratory rate greater than or equal to 50/min or chest indrawing, or of both signs, was a good indication of pneumonia, with a predictive power of 46% for a positive test and 83% for a negative test. A more complex definition of tachypnoea, as a respiratory rate greater than or equal to 40/min in children over 12 months old and greater than or equal to 50/min in infants, showed little additional diagnostic benefit.

A 65-year-old man was admitted to our hospital complaining of productive cough, dyspnea and stridor. Chest X-ray disclosed overinflation with micronodular infiltrates. Blood examination showed mild eosinophilia and IgE elevation. Pulmonary function test disclosed severe airway obstruction and diffusion capacity impairment. Although clinical improvement was achieved after bronchodilator therapy, laboratory abnormalities continued. Open lung biopsy demonstrated mononuclear cellular and eosinophilic infiltration at alveolar lumen and vessel walls without prominent fibrosis, which was compatible for prolonged eosinophilic pneumonia. From above findings, this case was thought as a prolonged eosinophilic pneumonia combined with pulmonary emphysema and bronchial asthma.

Twenty-seven main bronchial resections (19 left, 8 right) were performed without pulmonary resection between 1975 and 1991. The patients were 17 men and 9 women with an average age of 35 years (range, 20 to 65 years). Tumors comprised 55% of the lesions, including 9 carcinoid tumors (33%), 2 mucoepidermoid tumors, 2 fibrous histiocytomas, 1 hemangiopericytoma, and 1 large cell carcinoma. Scarring and stenosis secondary to multiple causes occurred in 10 patients (37%). Two patients had miscellaneous lesions. Presenting symptoms included dyspnea (52%), wheezing or stridor (44%), cough (41%), hemoptysis (37%), and pneumonia (18%). Preoperative chest roentgenogram was abnormal in 60% of patients, whereas tomograms delineated the lesion in 94%. All patients had bronchoscopy for lesion evaluation. Anesthesia was accomplished through a long single-lumen endotracheal tube in 19 cases and a double-lumen tube in 8 cases. Mobilization and exposure techniques to create a tension-free anastomosis were critical for left main bronchial resections and included pretracheal mobilization (100%), neck flexion (100%), tracheal and main bronchial retraction (85%), aortic and pulmonary artery retraction (44%), and intrapericardial hilar release (33%). All resections were for cure; there was no operative mortality. Morbidity in 4 patients (15%) included an anastomotic stenosis (successfully reresected), prolonged air leak and pneumonia, transient recurrent nerve palsy, and atelectasis. Median 5-year follow-up revealed 92% of patients alive, with only one of two late deaths being disease-related. Main bronchial resection is an ideal technique for selected benign and malignant lesions, allowing complete pulmonary parenchymal preservation.

Bacterial tracheitis (BT) was found in 10 of 748 children (1.3%) admitted with croup during 1983-1990. 9.9% of all the 748 croup cases seen (74) were admitted to the pediatric intensive care unit (PICU) and 16 of the 74 required intubation. 10 of those intubated (62.5%) were found to have BT and had typical features of croup, including inspiratory stridor, hoarseness and cough. Airway obstruction resulted mainly from accumulated tracheal pus. After endotracheal intubation all required frequent suctioning of thick purulent secretions. In 2 children causative microorganisms were cultured from the blood, and in all 10 from the tracheal pus. All children were given antibiotic therapy but a 7 month-old girl died of secondary complications (respiratory syncytial virus infection, pneumonia and adult respiratory distress syndrome). The others recovered and were discharged from the PICU within 3-14 days. BT should be suspected when tracheal intubation is required in croup. In such cases close monitoring in a PICU and frequent tracheal suctioning after intubation is necessary; antibiotic therapy should be considered.

Thirty consecutive patients undergoing lung resections were randomized into two groups: Group A (n = 15) received minitracheotomy postoperatively and group B (n = 15) were control patients. Postoperative respiratory course was monitored by serial clinical assessments, chest x-ray examination, arterial blood gases, sputa bacterial cultures, and the patient's requirement and response to chest physiotherpy. The two groups were similarly matched in age (mean 58.5 years), smoking habits, pulmonary functions, and surgical procedures. Postoperative pulmonary complications of collapse/consolidation developed in 11 patients (two in group A and nine in group B) (p less than 0.03). Four patients (all in group B) required nimitracheotomy in addition to antibiotics and chest physiotherapy to treat their pneumonia. Chest physiotherapy requirement was less in group A than in group B, with a mean number of sessions of seven in group A and eight in group B and a mean total time of 92 minutes in group A and 112 minutes in group B. The mean duration of minitracheotomy was 4.13 days. Minor temporary symptoms resulted from the minitracheotomy in eight patients (42%) and included discomfort, voice changes, subcutaneous emphysema, and stridor. There was one case of long-term morbidity (5%)-skin scarring from wound infection at the site of the minitracheotomy. No postoperative deaths resulted. We conclude that the prophylactic use of minitracheotomy is safe and effective in decreasing postoperative respiratory complications in patients undergoing lung resections.

We have used flexible fibreoptic bronchoscopy using sedation and local anaesthesia in 50 children aged 2-19 years (median 10) using an Olympus BFP20 instrument. Indications were opportunistic pneumonias (n = 11), persistent atelectasis (n = 11), recurrent pneumonia (n = 7), miscellaneous lower airway disease (n = 7), recurrent wheezing (n = 3), haemoptysis (3), to diagnose infection or rejection of heart-lung transplants (n = 3), stridor (n = 2), suspected airway compression (n = 1), evaluation of tracheostomy (n = 1), and suspected foreign body (n = 1). In 43 cases (86%) the diagnosis was related to the primary indication. In five (10%) unrelated abnormalities were found, and five (10%) were normal. In 13 (26%) treatment was altered as a result of flexible fibreoptic bronchoscopy. Complications were transient respiratory arrest (n = 2), hypoxia (n = 2), pneumonia (n = 2), and laryngospasm (n = 1). All complications were followed by complete recovery. Our results suggest that flexible fibreoptic bronchoscopy is safe. Advantages over rigid bronchoscopy include greater visual range, fewer complications, and the avoidance of a general anaesthetic. Though invasive it can yield important diagnostic and therapeutic information.
