Increased incidence of head and neck abscesses in children

Objective To describe increasing incidence and changing microbiology of head and neck abscesses in children admitted to the hospital during the first quarters of 2000 through 2003. Study Design and Setting Retrospective data warehouse review identified 89 children less than 19 years of age admitted to a tertiary care pediatric hospital during the first quarters of 2000 through 2003 for suspicion of head and neck abscess involving the neck, face, and peritonsillar, retropharyngeal, and parapharyngeal spaces; and for orbital and intracranial complications of acute sinusitis. Outcome Measures Outcome measures included the incidence of infection admissions and description of infection location and microbiology, calculated by χ2 technique. Results The incidence of infections increased in 2003. The greatest increase was in neck abscesses and complications of acute sinusitis. Conclusions The increase in group A strep infections may be related to its biologic properties. Significance Group A strep remains a significant cause of head and neck infections in children.

PREVENTION AND MANAGEMENT OF AERODIGESTIVE FOREIGN BODY INJURIES IN CHILDHOOD

Pediatricians have a critical role in the evaluation of children who experience a choking episode and foreign body injury. Familiarity with important symptoms and signs improves diagnostic skills and complements radiographic evaluation. Further reduction in injury prevention is assisted by parental education and avoidance of objects and foods that produce the greatest risk. Design modifications of toys and other products for childrens use is the next important step in this safety process.

The Role of Extraesophageal Reflux in Otitis Media in Infants and Children

Objectives/Hypothesis: Gastroesophageal reflux disease (GERD) is common in children, and extraesophageal reflux disease (EORD) has been implicated in the pathophysiology of otitis media (OM). We sought to 1) determine the incidence of pepsin/pepsinogen presence in the middle ear cleft of a large sample of pediatric patients undergoing myringotomy with tube placement for OM; 2) compare this with a control population of pediatric patients undergoing middle ear surgery (cochlear implantation) with no documented history of OM; 3) analyze potential risk factors for OM in children with EORD demonstrated by the presence of pepsin in the middle ear cleft; and 4) determine if pepsin positivity at the time of myringotomy with tube placement predisposes to posttympanostomy tube otorrhea.

Detection of Gastric Pepsin in Middle Ear Fluid of Children with Otitis Media

OBJECTIVE: We sought to confirm the finding of pepsin/pepsinogen in the middle ear fluid of children with otitis media in a larger sample size using a sensitive and specific pepsin assay. STUDY DESIGN AND SETTING: We evaluated 152 children (225 ear samples) in a prospective study at a tertiary care childrens hospital. The presence of pepsin in middle ear aspirates was determined using enzymatic assay. RESULTS: Of the patients, 14.4 percent (22 of 152) had detectable pepsin activity in one or both of the ear samples with no pepsin activity detected in control serum. Average pepsin concentration in the samples was 96.6 ± 170.8 ng/ml, ranging from 13 to 687 ng/ml. Pepsin concentration in the middle ear of children younger than 1.0 year was significantly higher than in older age groups. CONCLUSION AND SIGNIFICANCE: Results indicate that pepsin/pepsinogen is present in the middle ears of children with otitis media, although not at the high rate previously reported. Gastric reflux may be one causative factor in the pathogenesis of otitis media.

Postoperative bilevel positive airway pressure ventilation after tonsillectomy and adenoidectomy in children — a preliminary report☆

Obstructive sleep apnea (OSA) in children, characterized by hypoventilation secondary to upper airway obstruction, often results from tonsil and adenoid hypertrophy. Adenotonsillectomy is the standard therapy in this patient population. The immediate postoperative period is complicated occasionally by respiratory difficulties that may require intubation and mechanical ventilation. Recently, physicians have provided temporary airway support using continuous and bilevel positive airway pressure (BiPAP) devices. Reported complications of positive airway pressure devices include local abrasions to the nose and mouth; dryness of the nose, eyes, and mouth; sneezing; nasal drip, bleeds, and congestion; sinusitis; increased intraocular pressure; non-compliance; and pneumocephalus. Subcutaneous emphysema following facial trauma, dental extractions, adenotonsillectomy, and sinus surgery has been reported. There is also a hypothetically increased risk of subcutaneous emphysema following the use of positive airway pressure ventilation in the tonsillectomy patient. Between January 1997 and July 1998, 1321 patients underwent tonsillectomy and/or adenoidectomy at our institution. In reviewing the records of all pediatric intensive care unit admissions during that time period, we identified nine patients, of the 1321, who required BiPAP postoperatively. Of these, four children were obese, four had preexisting neurological disorders, and one underwent endoscopic sinus surgery and adenoidectomy. Three children were asthmatic, and three were less than 3 years of age. Two obese children were discharged with home BiPAP, one of whom had been on BiPAP prior to surgery. All patients tolerated BiPAP without complications. This preliminary report suggests that BiPAP is a safe and effective method of respiratory assistance in the adenotonsillectomy patient with preexisting conditions who is predisposed to postoperative airway obstruction. Furthermore, with BiPAP, the risks of intubation and ventilator dependence are avoided.

Adenotonsillectomy in the morbidly obese child

OBJECTIVE The prevalence of obesity in the pediatric population has risen more than 20% in 25 years. Accordingly, surgical procedures on obese children have become more common. Adenotonsillectomy (AT) remains among the most frequently performed pediatric surgical procedures in the United States. Our objective was to determine if there is an increased complication rate in morbidly obese (MO) children undergoing AT and if elective pediatric intensive care unit (PICU) admission for observation is warranted. METHODS This retrospective study includes postoperative admissions to the PICU over a 4-year period at one hospital. Out of 957 adenotonsillectomies performed by one surgeon, 543 were admitted to the hospital. Fourteen MO children were identified. Using body mass index (BMI; weight in kg/m(2)), as calculated for age appropriate categories, postoperative outcomes of AT in MO children (>95th percentile BMI) were determined. These 14 were electively admitted to the PICU for airway observation. The indication for surgery in these 14 children was obstructive sleep apnea. Ages ranged from 4 to 15 years. There were 11 males and 3 females. RESULTS Two patients required overnight bi-level positive airway pressure (BiPAP) for oxygen desaturation. One patient remained intubated for 10 days. Three patients required supplemental oxygen. Four of these admissions had preoperative polysomnograms (PSGs). CONCLUSIONS Our study concluded that routine PICU admission was not warranted for most MO patients although several required supplemental oxygen, BiPAP, and one required intubation. These interventions can easily be administered in a surgical floor bed. In fact, these results imply that performing this surgical procedure in obese children is not as risky as many believe. Trends were noted for an increased need of airway interventions in children requiring preoperative BiPAP and in those with comorbidities. In this small population, sample AT was performed on the basis of history. This is to serve as a pilot review for a prospective study in which preoperative PSGs would be used to determine potential indicators for elective PICU admission.

Powered Intracapsular Tonsillectomy in the Management of Recurrent Tonsillitis

OBJECTIVE: To compare intracapsular tonsillectomy (IT) and traditional tonsillectomy (TT) in treating recurrent adenotonsillitis or streptococcal pharyngitis. DESIGN: Retrospective chart review. SETTING: Tertiary care pediatric referral center. RESULTS: Of 166 patients who met all inclusion criteria, 117 received TT and 49 received IT. Seventeen TT patients and 8 IT patients were treated at least once postoperatively for streptococcal pharyngitis or tonsillitis. The mean number of infections after surgery in each group did not reach statistical significance (P = 0.295). CONCLUSION: There was no difference between the IT and TT groups in postoperative infection rates.

The feasibility of office-based laser-assisted tympanic membrane fenestration with tympanostomy tube insertion: the duPont Hospital experience.

OBJECTIVE To determine the feasibility of inserting tympanostomy tubes in children using office-based laser-assisted tympanic membrane fenestration. METHODS AND MATERIALS Study consisted of a retrospective review of the charts of all children who underwent office-based laser-assisted tympanic membrane fenestration with tympanostomy tube insertion from July 1, 1998 to August 31, 2000. Tetracaine eardrops were used for topical anesthesia. Fenestration was achieved with the OtoLAM flashscanner laser (ESC Sharplan, Yokneam, Israel). RESULTS Of the 127 patients (185 ears) who underwent laser-assisted tympanic membrane fenestration, 61 ears underwent tympanostomy tube insertion. Ten ears were treated for otitis media with effusion, 43 for recurrent acute otitis media, and eight for acute otitis media not responding to antibiotics. Fifteen ears had purulent effusion, five had a serous effusion, and 23 had mucoid middle ear fluid. Eighteen ears had no middle ear fluid. At the first follow-up visit, all tested ears had hearing of 20 dB or better. Two children had tubes that were blocked. Blockage occurred in ears that required more than one laser firing to penetrate the tympanic membrane. Otorrhea was present in 13 ears (21%). Otorrhea occurred exclusively in ears with purulent or mucoid middle ear fluid. CONCLUSIONS Office-based laser-assisted tympanic membrane fenestration with tympanostomy tube insertion is a safe and effective alternative to tube placement in the operating room. The outcome compares favorably with previously published data.

Plastic bronchitis : a case report

We report a case of perioperative management of a toddler with plastic bronchitis complicated by tracheal obstruction. We discuss our management of this case as well as the diverse group of patients who may present with this disease. We also reviewed the literature regarding medical management of cast bronchitis.

Effectiveness of adenoidectomy and laser tympanic membrane fenestration.

Objective Adenoidectomy alone or with tonsillectomy (A±T) is an effective surgical intervention in the management of otitis media in children, especially when it is performed in conjunction with insertion of pressure equalization tubes (PETs). Otorrhea and persistent tympanic membrane (TM) perforation are frequent complications. This study evaluates the effectiveness of intermediate duration middle ear ventilation using laser tympanic membrane fenestration (LTMF) without tube insertion and as an adjunct to adenoidectomy in resolving middle ear disease within the first 90 days after surgery.
