Choking on pins, needles and a blowdart: aspiration of sharp, metallic foreign bodies secondary to careless behavior in seven adolescents.

OBJECTIVE: To review the demographics, pathophysiology and management of aspiration of sharp, metallic foreign bodies; to review prevention strategies. DESIGN: Case series and review of the related literature (1932-2006). SETTING: Tertiary care pediatric hospital. PATIENTS: All patients presenting to BC Children's Hospital with aspiration of sharp, metallic foreign bodies since 1998. RESULTS: The seven patients ranged in age from 11 to 15 years (mean 13 years). The two boys had been playing with other boys at the time of aspiration. One aspirated a thumbtack and one aspirated a homemade blowdart (which traveled from his carina to his subglottis with coughing). Three of the five girls had been holding thumbtacks or a darting pin between their lips while putting up posters or sewing. The other two girls, who aspirated thumbtacks, refused to provide a history. One was treated successfully 6 days after the aspiration. The other girl withheld the history for over a year, presented with hemoptysis and eventually required thoractomy and right main bronchotomy to remove the tack. All of the other patients were diagnosed and successfully treated by rigid bronchoscopy within 24h. (Two patients initially had a failed attempt at foreign body removal by flexible bronchoscopy at another hospital.) This is the second largest series of aspiration of sharp, metallic foreign bodies since at least 1966. Adolescents are still aspirating sharp, metallic foreign bodies because of the same behaviors described by Jackson and Jackson in 1932. Education about choking hazards is needed for this age group. CONCLUSIONS: Aspiration of a sharp, metallic foreign body is a serious injury which is best treated by rigid bronchoscopy. These injuries potentially could be prevented through education.

Tourette syndrome and otolaryngology.

Tourette syndrome (TS) is the most complex tic disorder and presents primarily in the pediatric population between the ages of two and 15. The otolaryngologist may be consulted to see such a patient because of head and neck or facial tics or more often because of phonic or vocal tics such as throat-clearing, sniffing, coughing or abnormal noises. As this disorder has not appeared in the otolaryngologic literature we undertook a retrospective chart review (N = 72) and follow-up questionnaire related to the otolaryngologic aspects of this disorder.

Management of hemangiomas of the head and neck in children.

Hemangiomas occur in approximately 1% of Caucasian children, and the head and neck is a common site of presentation. Lesions in this region may cause morbidity and occasionally mortality by virtue of complications such as ulceration, infection, hemorrhage, hemodynamic change, aerodigestive tract obstruction and disfigurement. The majority of hemangiomas regress spontaneously. Those with impending complications may require treatment with several modalities. Embolization, surgery, laser therapy, cryotherapy and medical therapy with steroids and antifibrinolytic agents may be used in selected situations. Radiotherapy is now rarely favored due to potential induction of late malignancies. The natural history of these lesions is discussed along with the treatment modalities available and indications for use. Several representative cases are presented.

Sinusitis in children.

Sixty-eight children with the primary diagnosis of sinusitis have been admitted to the B.C. Children's Hospital since its opening in 1982 until July of 1986. Sinusitis in children under six years differs in presentation and course from sinusitis in older children. Children under six years seem to respond well to antibiotics while some children over six need surgery. Underlying diseases were present in half the cases and should be searched for in children who present with recurrent sinusitis.

Tracheobronchial and esophageal foreign bodies in the pediatric population.

A foreign body lodged in the aerodigestive tract of a child often poses a difficult medical problem. Experience with the diagnosis and removal of these foreign bodies is presented in this retrospective review. The description by a witness of the actual ingestion frequently provided the key to diagnosis. Rigid endoscopy remains a safe technique for foreign body extraction with a low resultant morbidity and mortality. Organic matter comprises the majority of bronchial foreign bodies (70%) while coins are the predominant finding (80%) in the esophagus.

The sleep apnea syndrome.

Four patients with sleep apnea syndrome were seen at the Vancouver General Hospital within the last three years and are discussed in this paper. The history of recognition of the syndrome, the types of apnea, and method of evaluation using polysomnographic techniques are reviewed, and methods of treatment are outlined.

Microbiology of recurrent and chronic otitis media with effusion.

A study was conducted of 274 children who had recurrent acute or chronic otitis media with effusion. Forty-five percent of the ears with effusion were found to contain bacteria, and 11% contained bacteria that were "probable pathogens" (S. pneumoniae, H. influenzae, and S. pyogenes). Bacteria were also found in 40% of the ears without effusions. The type of organism found did not vary with the age of the patient studied or the season of the year. The significance of these bacteria in the etiology of recurrent acute or chronic otitis media with effusion remains to be demonstrated.

Tissue-space emphysema, tissue necrosis, and infection following use of compressed air during pulp therapy: case report.

The intraoperative development of tissue-space emphysema in a child undergoing restorative treatment under general anesthesia is presented. Emphysema development seems to be concomitant with the use of compressed air around patent root canals, complicated by tissue destruction due to movement of canal irrigants/medicaments into the periapical tissues and by secondary infection. Several recommendations for the prevention of tissue-space emphysema are presented including the use of a rubber dam, judicious use of compressed air, and maintenance of canal irrigants and medicaments within the root canal. Treatment recommendations vary from palliative care with follow up in cases of facial emphysema to immediate medical attention in cases of pharyngeal or mediastinal emphysema.
