Forty-six pediatric flexible fiberoptic bronchoscopies were done on 29 infants under 1 year of age, including a 2.3-kg 1-week-old infant girl, and 17 small children between 1 and 2 years of age with persistent unilobar or multilobar atelectasis and declining PaO2 or rising PaCO2. Atelectasis resolved in all 29 infants (100%) and 10 of 17 (59%) small children after direct visualization, bronchial washing, and removal of mucous plugs and/or secretions using a flexible fiberoptic bronchoscope (FFB). The procedure was not associated with any mortality or significant morbidity. Only one infant experienced minor epistaxis and another had transient minimal stridor. None of the 17 small children developed complications. The procedure resulted in resolution of respiratory distress and cough within 24 hours, as well as early hospital discharge in all patients regardless of complete or partial radiographic expansion. Arterial blood gases were improved or normalized in 16 patients. When utilized for selective aspiration of mucous plugs or bronchial secretions, pediatric flexible bronchoscopy is particularly helpful in children with segmental or lobar atelectasis.

A case of massive symptomatic cystic hygroma confined to the left hemithorax and mediastinum in a 21-month-old boy is reported. The symptoms were of increasing respiratory distress and cough with fever. The mass surrounded all of the major vascular and nervous structures of the mediastinum and left hemithorax and was attached to the pericardium. It was excised, and the postoperative course was complicated by prolonged chylothorax and malfunction of the left hemidiaphragm. Seven other reported symptomatic cases of cystic hygroma confined to the thorax in early childhood are reviewed. The hygromas tend to be large and their care typically is complex and complicated. Hemorrhage into the cysts is a frequent finding and likely contributes to the acute and progressive symptoms.

In 16 newborns with respiratory distress syndrome (RDS) not artificially ventilated, oesophageal pressure was recorded with an electromanometer and the reactions to mechanical stimulation of the upper airways by means of a nylon fibre were investigated. The results were compared with the values obtained in 16 newborns without cardiorespiratory disturbances. The reactions were evoked by mechanical stimulation of the airways. Mechanical stimulation of the nasal mucosa produced expulsive reactions only in 45% of cases in newborns with RDS as compared with 95% in healthy newborns (p less than 0.001). Stimulation of the oropharyngeal and laryngeal regions elicited expulsive reactions in 48% of cases in newborns with RDS, but 74% in healthy newborns (p less than 0.001). In other cases, inhibition of breathing or apnoea was the most common reaction. The expulsive component of responses such as sneezing, expiratory reaction and crying was weaker in newborns with RDS than in control infants. The inspiratory component of sneezing and coughing, on the contrary, was stronger in newborns with RDS. These results indicate that active elimination of irritants from the airways is reduced in newborns with RDS.

We administered 45 Nd-YAG laser treatments in 29 patients (18 men) aged 39 to 82 years who had lung malignancy; 26 patients had primary non-oat cell lung cancer and three had metastatic airway malignancy. In all, 25 of the patients had been previously treated with combination(s) of surgical procedure, radiation therapy and chemotherapy. Indications for laser treatment included endobronchial airway obstruction with uncontrolled cough, hemoptysis, dyspnea or unresolved atelectasis-pneumonia. Of 15 patients with partially occluded tracheobronchial airway tumors, immediate palliative relief was achieved in 13 patients and lasted one to six months after a single treatment. In this group there was one postoperative death related to respiratory failure and two patients subsequently died of massive pulmonary hemorrhage. However, of 14 patients with totally obstructed airways, immediate palliative relief was achieved in only five patients and this lasted three weeks to three months after a single treatment. In this group there were two postoperative deaths related to progressive respiratory failure; in one case it was associated with endobronchial combustion of the fiberoptic bronchoscope. All three patients in both groups who died of respiratory failure were in acute respiratory distress and terminally ill before the procedure. These findings suggest that Nd-YAG laser therapy may be most beneficial in patients with partially rather than totally occluded airways due to lung malignancy.

Primary tumors of the lung rarely occur in children. However, 230 well-documented cases, including the 2 presented in this review, have been identified in the English-language literature. One hundred fifty-one tumors in these reports were classified as malignant lesions and 79 as benign neoplasms. Bronchial "adenomas" constituted the largest group; most of these lesions were of the carcinoid variety, and 8% were definitely malignant. Forty-seven cases of bronchogenic carcinoma were reported in children under 16 years of age, although there were few squamous cell tumors (12%). Fifty-six percent of the benign tumors were classified as inflammatory pseudotumor. Most of the children in this collective series were seen with symptoms related to bronchial irritation or obstruction, such as cough, hemoptysis, atelectasis, or pneumonitis. Respiratory distress was an unusual symptom that was often associated with large tumors seen in the neonatal period. Approximately 20% of the children were totally symptomatic. The limited survival data that are available indicate that leiomyosarcoma and mucoepidermoid carcinoma have a more favorable prognosis in children than in adults. Survival with bronchial carcinoid tumors (90%), bronchogenic carcinoma (30%), and pulmonary blastoma (45%) appears to parallel that for adults. The experience with pulmonary rhabdomyosarcoma, as described in this review, emphasizes the importance of early diagnosis and the use of combined modes of therapy in the approach to these malignancies. Despite the rarity of primary pulmonary neoplasms in children, this diagnosis should be considered in young patients with solitary pulmonary masses or persistent, atypical pulmonary symptoms. It is hoped that early diagnosis will result in an improved prognosis and prevent life-threatening complications.

Croup syndromes are common in children, most frequently being infectious in origin. Children present with a slow progression of inspiratory and expiratory stridor and a croupy, "barking seal" cough. Children are variably febrile and with progression of disease, exhaustion, agitation, cyanosis and air hunger may develop. The evaluation of the patient must focus on the degree of respiratory distress and associated findings. Epiglottitis and foreign body aspiration must be excluded. Management is primarily dependent upon administration of humidified air. Children with moderate to severe croup benefit from racemic epinephrine and steroids. Admission is indicated in children with stridor at rest, evidence of exhaustion, toxicity or respiratory distress. Active airway intervention is rarely required but may be life saving if obstruction develops.

Foreign body in the tracheobronchial tree is a relatively infrequent, but, potentially fatal event, requiring rapid and expert intervention. The symptoms and signs may be mistaken for asthma and pneumonia, - or, as in the case described, with grand mal epileptiform seizures. This emphasises the need to take a thorough case history, and to have a high index of suspicion in a case presenting with convulsion associated with cough, wheezing or respiratory distress.

Pulmonary artery sling is a rare cause of respiratory distress the embryological origin of which is not known. Two patients with this abnormality, both of whom are now thriving, are described. Surgery was necessary at the age of 5 1/2 years in one child, who also had an atrial septal defect. The other child, at the age of 2 years, shows improvement of her wheezing, cough, and breathlessness despite having had neither surgical nor medical treatment.

Foreign body aspiration is the cause of death in over 500 children per year in the United States. Tracheobronchial inhalation of foreign bodies may result in acute respiratory distress, chronic pulmonary infections, atelectasis, or death. A review of 262 children ranging from 4 months to 13 years of age was undertaken to identify factors important in diagnosis to illustrate the effectiveness of newer endoscopic techniques and equipment, and to evaluate results and complications. Coughing, choking, and wheezing were the presenting symptoms seen in 91 percent of the patients. Inspiratory and expiratory chest radiographs were positive in 81 percent of the 224 children with foreign bodies removed. Fluoroscopy was positive in 41 patients, 88 percent of whom had foreign bodies removed. Bronchoscopy is required for treatment, and with experience, this procedure can be simple and safe. Ninety-nine percent of foreign bodies identified at bronchoscopy were removed successfully. Minor complications occurred in 8 percent of the patients, and there were no deaths.

The case is reported of a 26-year-old patient hospitalized after 6 days of coughing and dyspnea with the clinical picture of "adult respiratory distress syndrome" (ARDS). In spite of intensive therapeutic efforts, death ensued within a few weeks. Autopsy revealed widespread intraalveolar metastases of a hitherto unrecognized amelanotic malignant melanoma of the back. Further metastases were only detected in intrathoracic lymph nodes and in the myocardium. A possible relationship between this unusual pattern of metastasis and previous abuse of nicotine, alcohol and hashish, as well as coexisting hypogammaglobulinemia, is discussed. It appears that widespread intrapulmonary metastasis must be considered one of the possible causes of ARDS.
