Life-threatening anoxic spells caused by tracheal compression after repair of esophageal atresia: correction by surgery.

Three infants who developed anoxic spells 2, 5, and 20 mo following repair of esophageal atresia developed apneic spells during or within a few minutes of feeding. These episodes began with stridor and cyanosis; when severe, they progressed to apnea and loss of consciousness. Mouth-to-mouth resuscitation was often necessary. Investigations failed to detect esophageal obstruction and/or a recurrent tracheoesophageal fistula. No neurologic or cardiac abnormalities were found. The cause was compression of a 1- to 3-cm segment of trachea anteriorly by a vascular structure and posteriorly by a dilated esophagus that emptied slowly because of poor motility. Endoscopy confirmed the x-ray findings. The aortic arch and innominate artery were suspended to the sternum anteriorly, which relieved the apneic spells in all patients.

Bronchoscopy in childhood.

One hundred and seventeen patients underwent 183 bronchoscopies with no fatalities. Thirteen patients had complications related to their bronchoscopy and not the underlying disease state. Only the 33 patients with a diagnosis of foreign body aspiration had a high (88%) correlation of the preoperative diagnosis or condition and the postoperative findings. Fifty-one of the 117 patients had normal bronchoscopies and the number of normal bronchoscopies in patients who had wheezing, croup, hoarseness, stridor, and chronic cough was high. Assessing justification for bronchoscopies despite the negative correlation of pre- and postoperative diagnosis is difficult due to many factors, including pediatrician and parental anxiety, and the recognized consequences of missing a foreign body or other lesion in the airway of a child. Using liberal criteria for justification. fewer than 10% of the patients in this series had an unwarranted bronchoscopy, and the safety of the procedure would indicate that bronchoscopy in a pediatric medical center should be performed with minimal clinical justification.

The use of omental pedicle flap for tracheobronchial reconstruction in infants and children.

For the surgical repair of long-segment tracheal stenosis, costal cartilage graft or extensive resection with end-to-end anastomosis has often been used. Both procedures have a risk of developing anastomotic leakage, which is potentially a lethal complication, or stenosis resulting from compromised blood supply to the tissue at the anastomosis. We have used omental pedicle flap (OPF) to seal the anastomotic line and to restore the vascularity of the graft and the trachea in an attempt to avoid fatal complications. During the period between 1986 and 1990, OPF technique was used in tracheobronchial reconstruction in six patients aged 4 months to 3 years; cartilage graft for extensive tracheal stenosis (4), tracheal resection and anastomosis (1), and bronchial resection and anastomosis (1). The omentum was separated from the colon to form an OPF with the right gastroepiploic vessels preserved. The OPF was brought to the upper trachea in the mediastinum through the retrosternal space. There was no immediate postoperative death due to anastomotic leak. Endotrachial tubes were removed in all patients. Four of the six are totally free of airway problems. One patient showed persistent stridor because of remaining stenosis at the cervical trachea. The remaining one patient who underwent bronchial resection developed anastomotic stenosis probably due to the compression of the floppy left main bronchus by adjacent aorta. The OPF seems to be an important surgical adjunct in order to eliminate fatal complications in tracheobronchial reconstruction.

Diagnosis and treatment of gastroesophageal reflux in 500 children with respiratory symptoms: the value of pH monitoring.

Gastroesophageal reflux (GER) usually presents with digestive symptoms, failure to thrive, and/or respiratory symptoms. During the 8-year period from 1981 to 1989, 1,153 children underwent 20-hour pH monitoring to assess GER. All patients were graded using the scoring system of Euler and Byrne. Patients were classified as severe (score greater than 50), moderate (score 25 to 50), and normal (score less than 25). Five hundred (43.3%) of these patients presented with respiratory symptoms including apnea, cyanosis, or "near miss" sudden infant death syndrome (36%), poorly controlled asthma (28%), recurrent bronchopneumonia (13%), bronchiolitis (9%), and miscellaneous symptoms such as intermittent dyspnea, chronic cough, and stridor (12%). Eight patients (2%) had cystic fibrosis. The ages ranged from 1 month to 20 years (mean, 19.5 months). Twelve patients had technically inadequate studies and were excluded. Severe reflux was present in 156 patients (31%) and moderate reflux in 159 patients (31%). All patients were treated initially by medical therapy for a minimum of 8 weeks. The majority of patients (81%) had resolution of their symptoms with change in position, thickened feedings, and, when indicated, additional therapy with metoclopramide, cisapride, or domperidone. Most of these patients were found to have a specific position, usually prone, which decreased reflux. The remaining 57 patients had documentation of persistent reflux by pH monitoring and underwent an antireflux procedure. Of those patients undergoing surgery 51 had severe reflux and 6 had moderate reflux. Forty-four patients had a posterior 270 degrees wrap (Toupet), 10 had a 360 degrees wrap (Nissen), and 3 had an anterior 180 degrees wrap (Boix-Ochoa).(ABSTRACT TRUNCATED AT 250 WORDS)

Balloon dilatation of long-segment tracheal stenoses.

Although a rare anomaly, congenital tracheal stenosis is associated with a high mortality. Surgical approaches proposed for this life-threatening lesion have included resection of localized stenoses; tracheoplasty involving interposition of cartilage, periosteum, or pericardium via an anterior tracheal split; or esophageal anastomosis to a posterior tracheal split. None of these techniques have provided uniformly satisfactory results, and all entail significant morbidity associated with the tracheal anastomosis. We have used endoscopic balloon dilatation in four children with critical airway obstruction from long-segment tracheal stenoses. In each of these patients, symptoms began early in life (from 2 weeks to 6 months of age) and consisted of respiratory distress from upper airway obstruction or recurrent episodes of stridor and chest retractions requiring hospitalization. The location of the tracheal stenoses varied, involving the upper third, middle third, middle half, and distal half of the trachea in the patients encountered. At bronchoscopy, the lumen was judged to be less than or equal to 1 mm in three of these patients. Dilatation was accomplished using Gruentzig balloon catheters in sizes ranging from 3 mm to (eventually) 8 mm, and produced a posterior split in the complete tracheal rings responsible for the stenosis in all patients, resulting in great increases in airway lumen. All children were improved following balloon dilatation, and three are currently doing well at 2.5, 3.0, and 3.0+ years postdilatation. One infant eventually died of airway obstruction incurred by severe bronchomalacia distal to the tip of an endotracheal tube that had been passed to the carina after sequential balloon dilatations.(ABSTRACT TRUNCATED AT 250 WORDS)

Bronchoscopy during the first month of life.

During the 6-year period from 1984 to 1989, 196 bronchoscopies were performed on 132 neonates. The indications were grouped into four categories: (1) difficulties in artificial ventilation or failure to wean the baby from the ventilator (52); (2) other respiratory difficulties (52); (3) audible stridor (16); and (4) routine preoperative or postoperative examination of esophageal atresia patients (12). The most common finding was laryngomalacia or tracheomalacia (31). Other findings were: obstructing tracheal or bronchial granulation or stricture (23), obstructing mucous plug (22), grave tracheobronchitis (11), tracheoesophageal H-fistula (5), laryngeal perforation (3), congenital laryngeal stenosis (2), and complete laryngotracheoesophageal cleft (1). Four patients had miscellaneous pathology. The findings were normal in 30 patients. A therapeutic procedure was included in 99 of the 196 bronchoscopies. Seven serious complications occurred during the operative bronchoscopies, two of them requiring immediate pulmonary surgery. All complications were successfully managed. In contrast, no complications occurred in the 97 purely diagnostic bronchoscopies. In experienced hands, bronchoscopy of the newborn is a safe and useful examination. Complications occur when therapeutic procedures are included. Therefore, operative bronchoscopy should only be performed in conditions in which immediate thoracotomy and pulmonary surgery can be performed.

Lingual thyroglossal duct cyst presenting in infancy.

Lingual thyroglossal duct cysts are a rare form of thyroglossal cysts. We present two infants, 10 and 12 weeks of age, with midline intraoral cystic swellings stretching from the base of the tongue to the thyroid cartilage. Complete excision of the cysts by Sistrunk's procedure were carried out. Both infants are well on follow-up, at 6 months postoperatively. Their unique presentation with regard to age, location, and symptomatology is discussed. Lingual thyroglossal duct cysts large enough to cause dysphagia, stridor, respiratory distress, and failure to thrive in infants have not been previously reported in the literature.

Extranodal sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) of the head and neck.

We report 14 cases of extranodal sinus histiocytosis with massive lymphadenopathy involving a variety of head and neck sites. The patients ranged in age from 3 to 70 years (median, 43 years). Nine cases occurred in women and five occurred in men. The clinical presentation varied depending on the site of occurrence and included nasal obstruction, stridor, proptosis, ptosis, decreased visual acuity, facial pain or tenderness, cranial nerve deficits, mandibular tenderness, and mass lesions. Head and neck sites involved by disease included the nasal cavity, paranasal sinuses, nasopharynx, parotid gland, submandibular gland, larynx, temporal bone, infratemporal fossa, pterygoid fossa, meninges, and orbital region. The majority of patients presented with involvement of more than one site. Nodal involvement was identified in four patients. Special stains for microorganisms were negative. The sinus histiocytosis with massive lymphadenopathy cells demonstrated an immunophenotypic profile supporting derivation from macrophage/histiocytic lineage. Treatment varied and included surgical excision with or without adjuvant therapy (chemotherapy, radiotherapy) or steroids. Several patients required more extensive surgery as a result of extension of their disease to adjacent structures or due to recurrent disease. Twelve patients are alive and either free of disease or have persistent disease. Two patients died, one as a result of complications of disease.

Factitious Hymenoptera allergic emergency: a report of a new variant of Munchausen's syndrome.

We report of the case of a young woman with three hospitalizations and six emergency room visits for treatment of bronchospasm and angioedema first thought to be the result of Hymenoptera venom allergic reactions. Because several features of her illness were not consistent with the usual course of Hymenoptera anaphylaxis and because of a known history of anaphylactic-type reactions following aspirin ingestion, a presumptive diagnosis of factitious anaphylaxis was considered, the medical staff was alerted to evaluate this possibility, and the diagnosis was established. Serologic testing supported the diagnosis. This variant of Munchausen's syndrome is a third type described as an allergic emergency. The others are peanut anaphylaxis and self-induced laryngeal stridor.

Clinical signs of pneumonia in children.

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.

Recognition of pneumonia by primary health care workers in Swaziland with a simple clinical algorithm.

In developing countries primary health care workers are being trained to manage and treat acute respiratory infections with a protocol developed by the WHO. We tested the ability of nurses and nursing assistants in Swaziland to recognise the signs and symptoms of pneumonia; with the results of a paediatrician's examination as "gold standard", sensitivities and specificities were calculated. Danger signs of stridor and abnormal sleepiness were poorly recognised (sensitivity 0-50%) by the health care workers, as was audible wheeze. Severe undernutrition, tachypnoea, and chest wall indrawing were well recognised. Overall, the recognition of pneumonia was good (sensitivity 71-83%, specificity 84-85%). These findings highlight topics for emphasis in training.

Congenital laryngeal defects.

Embryologic disorders of the larynx are rare. The main symptoms are stridor and hoarseness, symptoms which in the newborn always necessitate further investigation. Both the laryngotracheo-esophageal cleft and the congenital laryngeal web are discussed in relation to the embryologic development of the larynx and to diagnosis and therapy. The use of the operating microscope is stressed.

Coexistant lesions of the pediatric airway.

Congenital stridor is frequently a perplexing clinical problem. The diagnosis is often elusive and can prove challenging. Two case presentations illustrate the difficulties involved when more than one lesion is present. The need for complete evaluation of the airway including laryngoscopy, bronchoscopy and barium swallow is stressed.

Acquired subglottic cysts in premature infants.

Advances in the management of premature infants have resulted in improved survival. However, long-term intubation may produce associated laryngeal complications. We report 12 infants and children who developed subglottic cysts following long-term intubation as newborns. The majority of the cysts were in the posterior subglottic larynx. Laser excision of the cysts was undertaken in 8 patients and 3 underwent removal with cupped forceps. Recurrent cysts in 3 patients required more than one endoscopic procedure. The differential diagnosis of stridor in infants who have required long-term intubation includes subglottic cysts. The cysts are not always obvious at endoscopy and indeed may be buried below the mucosa within a soft tissue subglottic stenosis. Their presence may be suspected when tiny beads of mucus are released when laser surgery of a soft tissue stenosis is applied. Successful management of these cysts includes early precise diagnosis, with careful identification of these cysts to differentiate them from other types of subglottic stenosis. An initial attempt of conservative management with endoscopic excision is made. If this fails, an anterior cricoid split may be indicated in cases where the cysts are associated with soft tissue subglottic stenosis. Tracheostomy may be unavoidable in some cases.

Subglottic neurofibroma in a child.

Reported here for the first time is a case of subglottic neurofibroma in an infant which was removed by laryngofissure. Neurofibromas are ubiquitous in distribution, but very rare in the larynx and also extremely rare in infancy. Only 9 cases had been reported in children under 9 years of age. In the present case, H.T., a boy aged 2 years and 7 months, complaining of inspiratory stridor since the beginning of December 1985, was admitted to our hospital on Jan. 21, 1986. The tumor was completely removed by laryngofissure and pathological diagnosis showed it to be a neurofibroma. Laryngeal neurofriboma cases are reviewed and discussed.

Lingual thyroid in a young infant presenting as airway obstruction: report of a case.

A case of lingual thyroid causing airway obstruction in a 3-month-old infant is reported. Endoscopic examination for stridor disclosed an obstructing 4 X 3 cm base of tongue lesion. Nuclear isotope scanning confirmed this to be the only thyroid tissue present in this patient. A transoral excision using the CO2 laser was performed without complication. Only one other case of airway obstruction in the young infant secondary to lingual thyroid has been reported, that being the original case description in 1869. A review of the embryology and discussion of the suggested therapies is presented. The rationale for use of the CO2 laser for this lesion is discussed.

Gastric heterotopia causing airway obstruction.

Two infants are reported each with a mass of heterotopic gastric tissue in the hypopharynx causing airway obstruction. Endoscopic laser removal of the tumours proved a satisfactory method of treatment. Gastric heterotopia in the head and neck region is rare but should be considered as a cause of stridor in infants.

Juvenile myasthenia gravis: an unusual presentation.

Myasthenia gravis is a disease characterized by muscular weakness and fatigability which afflicts 2-10 patients per 100,000 with 20% of cases presenting in childhood. Muscles innervated by cranial nerves are frequently involved with ptosis and diplopia being the most frequent presenting complaints. We review the literature and report a case of a 20-month-old infant presenting with inspiratory stridor and cyanosis, resembling foreign body aspiration.
