RESUMO

Rhabdomyoma is an uncommon benign tumor, with the majority arising from cardiac muscle. Seventy to 90% of extracardiac rhabdomyomas are found in the head and neck region, usually within the upper aerodigestive tract. The case of a 7-month-old boy with an enlarging posterior triangle neck mass found to be fetal rhabdomyoma is presented. This location is quite rare for benign rhabdomyoma, with previous literature search showing overwhelming predilection for the upper aerodigestive tract.

RESUMO

OBJECTIVES: (1) To test the feasibility of a rabbit model using a pharyngostomy tube to simulate gastroesophageal reflux and (2) to study the effects of gastroesophageal reflux on laryngotracheal reconstruction using a new rabbit model. DESIGN: Prospective randomized trial. SUBJECTS: Thirty-three New Zealand white rabbits. INTERVENTIONS: Anterior cartilage laryngotracheoplasty and pharyngostomy tube placement into the pyriform sinus were performed in 33 rabbits, 22 of which are included in this analysis. Beginning postoperative day 1, hydrochloric acid at a pH of 1.5 with pepsin (n = 7) or at a pH of 4.0 with pepsin (n = 8) was irrigated twice daily through the pharyngostomy tube to simulate gastroesophageal reflux, and a control group received twice-daily isotonic sodium chloride solution irrigations (n = 7). MAIN OUTCOME MEASURES: Specimens were scored by a pathologist masked to individual groups using a newly modified inflammation scoring system. In addition, cross-sectional areas of the cartilage grafts and subglottic airway lumina were compared. RESULTS: Inflammation scores were significantly higher in rabbits receiving hydrochloric acid and pepsin irrigations at a pH of 4.0 (P =.04) but not in those in the pH 1.5 group. Cartilage necrosis was prominent in all groups, and airway sizes and cross-sectional areas of the grafts were not significantly different among the 3 groups. CONCLUSIONS: Cartilage necrosis is prominent during the early stages after laryngotracheoplasty. Inflammation can be increased using hydrochloric acid and pepsin irrigations but is difficult to predict based on this study. Although we confirmed the feasibility of this model, further modifications of this study are proposed to improve animal survival and data collection.

RESUMO

Foreign body aspiration in children is a relatively common occurrence, with peanuts, seeds, or other food particles representing the most common items. Because radiological findings such as mediastinal shift, postobstructive emphysema, and pneumonia are notoriously inconsistent, diagnosis hinges on an accurate history, which may be correlated by physical examination and radiography. We present the case of a 2-year-old girl with delayed treatment of a bronchial foreign body who presented with tension pneumothorax before endoscopy. After chest tube removal, her pneumothorax recurred, thereby bringing about the question of bronchial erosion. Furthermore, an uncommonly reported aspirated object, household potpourri, was encountered.

RESUMO

OBJECTIVE/HYPOTHESIS: To study the outcomes and complications associated with pediatric tracheotomy, as well as the changing trend in indications and outcomes since 1970. STUDY DESIGN: Retrospective chart review at a major tertiary care children's hospital. METHODS: On children who underwent tracheotomy at Children's Hospital of the King's Daughters (Norfolk, VA) between 1988 and 1998, inpatient and outpatient records were reviewed. Of 218 tracheotomies, sufficient data were available on 204. Indications for tracheotomy were placed into the following six groups: craniofacial abnormalities (13%), upper airway obstruction (19%), prolonged intubation (26%), neurological impairment (27%), trauma (7%), and vocal fold paralysis (7%). RESULTS: The average age at tracheotomy was 3.2 +/- 0.6 years. Although the prolonged intubation group was significantly younger than all others, the neurological impairment and trauma groups were significantly older. Decannulation was accomplished in 41%. Time to decannulation was significantly higher in the neurological impairment and prolonged intubation groups, but was significantly shorter in the craniofacial group. Complications occurred in 44%. Overall mortality was 19%, with a 3.6% tracheotomy-related death rate. Comparison of our series to other published series of pediatric tracheotomies since 1970 shows fewer being performed for airway infections and more for chronic diseases, with a corresponding increase in duration of tracheotomy and decreased decannulation rates. CONCLUSIONS: Tracheotomy is a procedure performed with relative frequency at tertiary care children's hospitals. While children receiving a tracheotomy have a high overall mortality, deaths are usually related to the underlying disease, not the tracheotomy itself.

RESUMO

Postsurgical follow-up of children with tympanostomy tubes is becoming a contentious issue in this era of managed care. Primary care providers believe themselves to be capable of evaluating these children. Otolaryngologists, on the other hand, have more specialized equipment available to them (suction apparatus, otomicroscopes, audiology devices, etc) for treating suppurative infections and monitoring the tympanic membrane for structural changes. In addition, the otolaryngologist is placed in an uncomfortable legal and ethical position if access to the patient with a tube-related complication is denied by the primary care provider. Attempts to develop an American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) policy statement have been hampered by a lack of data on the incidence and severity of tube-related complications and the role that otolaryngologists can play in reducing these sequelae. A survey designed by the AAO-HNS Pediatric Otolaryngology Committee was distributed to 1000 board-certified otolaryngologists and all members of the American Society of Pediatric Otolaryngologists and the American Academy of Pediatrics-Otolaryngology Section regarding current practice patterns and practitioners' experiences with tympanostomy tube complications. Specific information regarding complications that could have been avoided with earlier otolaryngology referral was also obtained. The results of the survey and its implications for AAO-HNS policy are presented.

RESUMO

Systemic lupus erythematosus (SLE) is a disease that may affect a number of organ systems, particularly the joints, skin, kidneys, heart, lungs, and immune system. Salivary gland involvement is usually associated with Sjögren's syndrome, in which lymphocytic acinar infiltrates predominate histologically. We present the case of a 29-year-old woman with SLE who developed bilateral parotid enlargement with a unilateral focus of parotid necrosis that was consistent with a cystic mass on computerized tomography. A biopsy of this lesion was histologically similar to a cervical lymph node biopsy in the same patient, with both specimens showing loss of architecture and foci of necrosis consisting of nuclear dust, histiocytes, and scattered plasma cells without formation of granulomata or presence of multinucleated giant cells; these findings are classic for SLE lymphadenopathy. We believe this to be the first reported case of focal necrosis in the parotid gland directly associated with SLE.
