Myringoplasty in the pediatric population.

The long-term results of myringoplasty in children, including closure of perforation and hearing improvement, were reviewed in relation to age, condition of the operated-on ear, and condition of the untreated ear. The overall success rate in 155 operations evaluated one year postoperatively was 79%. Children in the 5- to 8-year-old age group had a success rate comparable to that of older (9- to 12-year-old) children (77.7% vs 80.4%). Where graft failure occurred, it was usually within one year of surgery. The outcome of surgery could not be related to the presence or absence of chronic otitis media in the untreated ear, the status of the operated-on ear (whether dry or discharging), or the performance of adenoidectomy before myringoplasty. Results of postoperative hearing, analyzed by calculating the postoperative air-bone gap and by speech audiometry, were similar in the two age groups. It is concluded that myringoplasty has a good chance of success in children, regardless of age.

Exacerbation of sickle cell disease by obstructive sleep apnea.

It is difficult to recognize and treat the factors that exacerbate the vascular crises of sickle cell disease. We describe a 12-year-old black girl with sickle cell anemia who, since the age of 9 years, has been repeatedly hospitalized for pain associated with vaso-occlusive disease. A diagnosis of obstructive sleep apnea was suggested by the history and physical examination and was confirmed by polysomnography. Following preoperative transfusion, the patient underwent elective tonsillectomy and adenoidectomy. She has been free of vaso-occlusive pain and crises for over two years and has not been hospitalized since her surgery. Post-operative polysomnography has shown no evidence of obstructive sleep apnea. It is our hypothesis that repeated oxygen desaturation during periods of obstructive sleep apnea was the cause of this patient's frequent vaso-occlusive crises. She not only obtained complete relief of her symptoms, but objective sleep study measurements were normal following surgery. Obstructive sleep apnea is a recent diagnosis, and its pathologic effects are only beginning to be known. Physicians taking care of patients with hemoglobinopathies need to be aware of possible contributing factors to their patients' disease, and an aggressive approach to their diagnosis and possible relief should be sought.

The efficacy of cefaclor vs amoxicillin on recovery after tonsillectomy in children.

Tonsillectomy and adenoidectomy continues to be one of the most commonly performed operations in the pediatric age group. The morbidity from tonsillectomy can be severe and includes throat and ear pain, fever, lethargy, and poor oral intake. A previous study at the Children's Hospital of Philadelphia (Pa) demonstrated the efficacy of amoxicillin therapy in minimizing some of these postoperative symptoms. However, some children continue to have a prolonged recovery even while receiving this antibiotic regimen. Because of these children and the high incidence of Staphylococcus found in tonsillar core tissue, a randomized, prospective study was undertaken at the Children's Hospital of Philadelphia to evaluate the efficacy of cefaclor vs amoxicillin in patients recovering from tonsillectomy. The patients received either ampicillin or cefazolin intravenously at the time of surgery and for 12 to 24 hours postoperatively. When oral intake was adequate, they received either amoxicillin or cefaclor orally for 7 additional postoperative days. Intraoperative cultures of the oropharynx and tonsillar tissue were obtained, as well as cultures of the tonsillar fossa 7 to 14 days postoperatively. The patients were evaluated for severity and duration of postoperative symptoms as well as complications. The results of this study showed no difference between the two groups of patients. We conclude that there is no justification for routine use of cefaclor over amoxicillin in the posttonsillectomy patient.

Management of tracheal lesions in Hurler syndrome.

Hurler syndrome is a rare mucopolysaccharide storage disease that becomes clinically apparent during early childhood as mucopolysaccharide deposits form in skeletal and soft tissues. Progressive mucopolysaccharide deposition in the oropharynx and tracheal connective tissues leads to airway obstruction if untreated. Tonsillectomy, adenoidectomy, and tracheostomy have been utilized to provide symptomatic relief of upper airway obstruction. Treatment of tracheal lesions by laser excision is a recent innovative method for the management of airway obstruction in children with Hurler syndrome. We describe two boys with Hurler syndrome whose mucopolysaccharide tracheal lesions were excised by utilization of the carbon dioxide laser.

Antral choanal polyp presenting as obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) in children is commonly caused by adenotonsillar hypertrophy. The diagnostic criteria of OSAS in children are not so well delineated as in adults. We report the first case of antral choanal polyp presenting as OSAS in a 10-year-old boy that initially presented to the child psychiatry service for behavior disturbance, enuresis, and daytime somnolence. Overnight electroencephalogram sleep study revealed events consistent with OSAS. Multiple inhalant allergies, chronic maxillary sinusitis, and obstructive adenoid hypertrophy were diagnosed by the allergy and otolaryngology services. The child was scheduled for adenoidectomy when his sleep apnea symptoms persisted following antimicrobial therapy. Examination under anesthesia revealed a normal adenoid bed and a large left antral choanal polyp. Polypectomy was performed as dictated by parental consent. Postoperatively treatment with an intranasal steroid was begun. However, polypoid nasal mucosa recurred in 2 months and a Caldwell-Luc procedure was performed. Subjective reports following surgery indicated improvement in daytime irritability, attention, and mood. A follow-up overnight electroencephalogram sleep study confirmed resolution of OSAS.

Bacteriology and immunology of normal and diseased adenoids in children.

Adenoid physiology as reflected in the qualitative and quantitative bacteriology and immune cell distribution was correlated with clinical presentation in 69 children (16 to 130 months of age) undergoing adenoidectomy for obstructive adenoid hyperplasia (n = 38) or chronic adenoid infection (n = 31) and in 16 adenoid core biopsy specimens from 16 nondiseased controls. In the control adenoids, few potentially pathogenic bacteria were found as the dominant bacteria in the adenoid core (25%), and significantly greater concentrations of nonpathogens (commensals) were isolated (P < .01). Potential pathogens as the dominant bacteria were found twice as often in obstructive adenoid hyperplasia (62%) and in chronic adenoid infection (55%) (P < .05). Haemophilus influenzae was most common in the diseased adenoids, 53% in obstructive adenoid hyperplasia and 48% in chronic adenoid infection, compared with only 19% in the controls (P < .05). No significant differences in lymphocyte density, B and T cells, as well as T-helper subsets, were found between clinical classifications. However, T-suppressor cells, monocytes-macrophages, and natural killer cells were significantly increased in chronic adenoid infection only (P < .05). The findings in this study support roles for both alterations in bacterial homeostasis and an altered immune profile in the etiology of chronic adenoid disease in children.

Which children are being operated on for recurrent acute otitis media?

OBJECTIVE: To examine at the population level which children were operated on for recurrent acute otitis media episodes, how ill they were, and what factors affected the operation rate. DESIGN: A retrospective birth cohort with an approximate 2-year follow-up. Infection data were gathered from medical records, and background information was gathered from questionnaires. SETTING: Primary health care centers, hospitals, and private practices in 10 randomly selected local government districts in the two northernmost provinces of Finland. SUBJECTS: A random sample of 2512 children from the cohort. OUTCOME MEASURES: Adenoidectomy and/or tympanostomy tube insertion. RESULTS: Only one of 10 of those with actual recurrent disease (> or = 4 episodes) had been operated on, and three of every five children operated on, in fact, had rather few episodes. The operation rate among those children with only a few episodes was increased by factors such as consulting an ear, nose, and throat specialist (risk ratio [RR], 13.0; 95% confidence interval [CI], 7.6 to 22.2); parental exaggeration of the episodes (RR, 6.7; 95% CI, 3.8 to 11.9); having the first episode under 6 months of age (RR, 4.5; 95% CI, 2.5 to 7.9); recurrent respiratory tract infections (RR, 3.3; 95% CI, 1.9 to 5.7); male sex (RR, 2.6; 95% CI, 1.4 to 4.6); urban domicile (RR, 2.4; 95% CI, 1.1 to 4.9); and day care (RR, 2.1; 95% CI, 1.1 to 3.8). The decision to operate was more or less a random phenomenon among those children with numerous episodes. CONCLUSIONS: Physicians at the primary care level should be familiar with these pitfalls concerning patient selection so that the operations are targeted at those children who are most seriously ill.

Prophylactic antibiotic drops after tympanostomy tube placement.

OBJECTIVE: To evaluate the effectiveness of prophylactic polymyxin B sulfate-neomycin sulfate-hydrocortisone drops in decreasing the incidence of posttympanostomy otorrhea. DESIGN: Prospective randomized controlled study. SETTING: University referral center. PATIENTS: Three hundred patients undergoing tympanostomy tube placement (including those undergoing tonsillectomy, adenoidectomy, or both) were randomized into three groups. INTERVENTION: The use of polymyxin B-neomycin-hydrocortisone drops. Patients in group 1 received no antibiotic drops; group 2, a single dose intraoperatively, and group 3, an intraoperative dose followed by a 5-day course. MAIN OUTCOME MEASURE: Posttympanostomy otorrhea. RESULTS: A statistically significant decrease was observed in the incidence of posttympanostomy otorrhea between the control (16.4%) and treatment groups (group 2, 8.3%; group 3, 8.1%) (P = .011). A single dose of antibiotics was effective when patients' middle ears were dry or had serous effusions. A 5-day course was indicated for those whose ears had mucoid or purulent contents. CONCLUSIONS: Antibiotic ear drops are indicated in all patients. A single dose is as effective as a 5-day course, but our data support a longer course in certain subgroups.

Use of intraoperative corticosteroids in pediatric tonsillectomy.

OBJECTIVE: To determine the effects of a single dose of dexamethasone sodium phosphate on postoperative morbidity in children undergoing tonsillectomy. DESIGN: Randomized, double-blind, placebo-control clinical trial. SETTING: Academic, tertiary care children's hospital. PATIENTS: Sixty-nine children (35 boys, 34 girls), aged 3 to 18 years, undergoing tonsillectomy with or without adenoidectomy. INTERVENTION: Patients were randomized to receive a single dose of intravenous dexamethasone or saline. MAIN OUTCOME MEASURES: Pain scores, determined by a Faces Scale, were obtained at 4-hour intervals during the first postoperative day and daily for 7 days thereafter. Total use of an analgesic; type of diet; level of activity; presence of halitosis, nausea, emesis, or fever; and incidence of postoperative bleeding were also compared between the two groups. RESULTS: The two groups of children were similar in age, gender, diagnosis, and surgical time. Pain scores in the postoperative period were identical while the patients were in the hospital and for the first 7 days after discharge. No statistically significant differences were noted in pain scores, nausea, emesis, halitosis, analgesic medications required, diet, or activity levels between the two groups of patients. CONCLUSION: A single intraoperative dose of dexamethasone did not appreciably affect postoperative morbidity in children undergoing tonsillectomy.

Water precautions in children with tympanostomy tubes.

OBJECTIVE: To compare the effectiveness of antibiotic ear drops (suspension of polymyxin B sulfate, neomycin sulfate, and hydrocortisone [Pediotic]), prefabricated ear molds, or no precautions in decreasing the incidence of posttympanostomy water-related otorrhea. DESIGN: Five-year prospective controlled study. SETTINGS: University referral center. PATIENTS: Five hundred thirty-three pediatric patients who were undergoing tympanostomy tube placement (including those who were undergoing tonsillectomy, adenoidectomy, or both) were self-selected into four groups. INTERVENTIONS: The use of antibiotic ear drops that contained polymyxin B, neomycin, and hydrocortisone and the use of prefabricated ear molds. Group 1 comprised patients who were not given any water precautions with swimming regardless of the depth or type of water; group 2 comprised patients in whom antibiotic ear drops were applied after all forms of swimming; group 3 comprised patients who used ear molds with all forms of swimming (all children were advised against diving and swimming more than 180 cm below the surface, and parents were cautioned to avoid the entrance of soapy water into their child's ears during bathing); and group 4 comprised patients who were selected not to swim at all (they served as a control group). RESULTS: No statistically significant difference was observed in the incidence of posttympanostomy swimming-related otorrhea among the three swimming groups (11%, 14%, and 20% of children in groups 1, 2, and 3, respectively, reported swimming-related otorrhea [P=.26, df-2, chi-square=2.66]). Children who did not swim at all (group 4) did not differ significantly in their overall incidence of otorrhea (59%) from the three swimming groups combined (68%) during the follow-up period (P=.11, df=1, chi-square=2.54). CONCLUSION: Young children with tympanostomy tubes who surface swim and do not dive receive no additional benefit from the taking of water precautions in the form of earplugs or antibiotic ear drops.

Pulmonary vascular complications of chronic airway obstruction in children.

OBJECTIVE: To study the clinical presentation, treatment, and outcome of pulmonary artery hypertension (PAH) that develops in children with chronic airway obstruction. DESIGN: Case study. SETTING: Academic tertiary care children's hospital. PATIENTS: A 3-year (October 1, 1992, to September 30, 1995) review of the medical records of all children with chronic airway obstruction in whom PAH developed. MAIN OUTCOME MEASURE: The clinical course, including objective laboratory data to measure PAH (cardiac catheterization, echocardiography, electrocardiography) both before and after treatment. RESULTS: Pulmonary artery hypertension developed in 18 patients. It was diagnosed using cardiac catheterization in 13 patients and echocardiography in 5 patients. Obstructive problems include chronic lung disease (9 patients), tracheobronchomalacia (6 patients), adenotonsillar hypertrophy (5 patients), laryngomalacia (4 patients), macroglossia (5 patients), subglottic stenosis (2 patients), and pharyngeal collapse (2 patients). Nine patients were born prematurely and 7 had Down syndrome. Treatments included tracheotomy (7), adenotonsillectomy (5), adenoidectomy (3), laser epiglottoplasty (1), and supplemental oxygen (12). Fourteen patients had documented improvement of PAH as seen from the cardiac catheterization, echocardiography, or electrocardiography findings; in 4 patients, PAH worsened (3 deaths). CONCLUSIONS: Chronic airway obstruction may lead to PAH. In this study, PAH was more likely to develop in premature infants or children with Down syndrome and cardiac anomalies. Surgery or supplemental oxygen will usually improve PAH, but fixed and irreversible PAH developed in patients with the most severe airway disease.

Risk of Hodgkin's disease subsequent to tonsillectomy: a population-based cohort study in Sweden.

Although some studies have linked excess of Hodgkin's disease (HD) to tonsillectomy, the findings have not been consistent. In particular, risk of HD by age at tonsillectomy has not been fully evaluated, despite the notable change in immunologic function of the tonsils between childhood and adulthood. To evaluate the risk of HD and other lymphomas, associated with tonsillectomy according to age at surgery, a population-based cohort study was conducted. Using nationwide Swedish hospitalization records, 55,169 patients undergoing tonsillectomy with/without adenoidectomy (T/A) were identified during the period 1964-1983. By linkage with the nationwide Total Population, Migration, Cancer and Causes-of-Death registries, these patients were followed up for as long as 25 years. After exclusion of the first post-operative year, a total of 533 first primary-cancer cases was identified between 1965 and 1989. Small excess risk was observed for HD (20 cases, SIR = 1.4, 95% CI 0.9-2.2). HD risk was more pronounced among patients tonsillectomized before age 12 (7 observed vs. 1.7 expected, SIR = 4.1, 95% CI 1.6-8.4), but declined significantly with older ages at T/A. While our data suggest a small increase in HD among all patients undergoing T/A and a significant excess for those under age 12 at surgery, we cannot exclude the possibility that the excess may be due to factors underlying the disorders that led to surgery.

Evaluation of pulmonary function and polysomnography in obese children and adolescents.

Obese adults have an increased prevalence of pulmonary disorders. Although childhood obesity is a common problem, few studies have evaluated the pulmonary complications of obesity in the pediatric population. We, therefore, performed pulmonary function tests (PFTs), polysomnography, and multiple sleep latency tests (MSLTs) in 22 obese children and adolescents [mean age, 10 +/- 5 (SD) years; 73 percent female; 184 +/- 36 percent ideal body weight], none of whom presented because of sleep or respiratory complaints. PFTs were normal in all but two subjects. Ten (46 percent) subjects had abnormal polysomnograms. There was a positive correlation between the degree of obesity and the apnea index (r = 0.47, P < 0.05), and an inverse correlation between the degree of obesity and the Sa0(2) nadir (r = -0.60, P < 0.01). The degree of sleepiness on MSLT correlated with the degree of obesity (r = -0.50, P < 0.05). We conclude that obese children and adolescents have a high prevalence of sleep-disordered breathing, although in many cases it is mild. Obstructive sleep apnea syndrome (OSAS) improved following tonsillectomy and adenoidectomy. We recommend that pediatricians have a high index of suspicion for OSAS when evaluating obese patients, and that polysomnography be considered for these patients.

Natural history of primary snoring in children.

It is not known whether children with primary snoring (PS) progress to develop obstructive sleep apnea syndrome (OSAS). Therefore, we repeated polysomnography in a cohort of 20 children diagnosed 1-3 years previously with PS. All children initially presented with symptoms suggestive of OSAS. They were diagnosed with PS when initial polysomnography demonstrated snoring, with less than one obstructive apnea per hour, normal gas exchange, and infrequent arousals. Of 75 potential candidates, 20 were available for reevaluation (33 could not be contacted, 8 had undergone tonsillectomy and adenoidectomy, and 14 declined). Mean age was 6 +/- 4 (SD) years at the time of the initial study. The initial apnea index was 0.2 +/- 0.3, SpO2 nadir 95 +/- 2%, and peak end-tidal PCO2 was 47 +/- 3 mm Hg. At follow-up, all children were reported by their parents to still be snoring; in 20% snoring had reportedly increased, and in 70% there was no change. Eighty percent were thought to have difficulty breathing during sleep. For the group as a whole, there were no significant changes in apnea index, SpO2, or peak end-tidal PCO2. However, two children had mild OSAS on repeat polysomnography (apnea index of 3). We conclude that, in most children, primary snoring does not progress to OSAS over the course of several years. This study indicates that OSAS in the few individuals who do progress is mild. Parental concern about children's breathing patterns during sleep is a poor predictor of polysomnographic abnormalities. However, because many patients were lost to follow-up in this study, further prospective studies are needed.

Determinants of bronchial responsiveness at school age in prematurely born children.

The bronchial challenge test using isocapnic hyperventilation of cold air (IHCA) was used to evaluate bronchial responsiveness in 63 offspring of multiple pregnancies when they were 8-15 years old. At birth, 27 (43%) children had had intrauterine growth retardation (IUGR, birth weight <-2 SD, or birth weight difference between twin pairs >1.3 SD). The median birth weight was 2,050 g (range, 800-3, 150), and the median gestational age was 35 weeks (range, 28-38). None of the children had asthma or suffered from asthma-like symptoms. In the interpretation of the IHCA test, a fall of 9% or more in the forced expiratory volume in 1 sec (FEV(1)) was considered as abnormal, and these children were classified as "cold air responders." The number of responders was 16 (25%); their baseline FEV(1)/forced vital capacity ratio (FEV(1)/FVC) and forced expiratory flow between 25-75% FVC (FEF(25-75)), but not FEV(1) were significantly lower than the corresponding values in nonresponders. No differences were found in perinatal or neonatal factors between responders or nonresponders. Eight (30%) of the 27 IUGR and 8 (22%) of the 36 appropriate for gestational age (AGA) children were IHCA responders. In particular, IUGR was not correlated with maximal FEV(1) falls following the IHCA test. Respiratory infections after the neonatal period were equally common in IUGR and AGA children; but infections were associated with subsequent IHCA responsiveness. Adenoidectomy, tonsillectomy, and/or myringotomy had been performed significantly more often in the responders than in the nonresponders. At least one of the above invasive procedures had been performed in 20 (32%) of the children; this group was termed the "ENT (ear, nose, throat) surgery group." Fifty-six percent of the responders, but only 26% of the nonresponders, belonged to the ENT surgery group (P = 0.02). We conclude that intrauterine growth retardation or prematurity is not associated with abnormal cold air responsiveness in the IHCA test.

Tonsillectomy versus non-surgical treatment for chronic / recurrent acute tonsillitis.

BACKGROUND: Surgical removal of the tonsils (tonsillectomy) is a common but controversial ENT operation. OBJECTIVES: To determine the effect of tonsillectomy in patients with chronic/recurrent acute tonsillitis. SEARCH STRATEGY: Cochrane Controlled Trials Register, Medline, Embase, bibliographies. SELECTION CRITERIA: Randomised controlled trials comparing tonsillectomy with non-surgical treatment in adults and children with chronic/recurrent acute tonsillitis. Trials which included reduction in the number and severity of tonsillitis and sore throat as main outcome measures. DATA COLLECTION AND ANALYSIS: Two authors applied the inclusion/exclusion criteria independently. MAIN RESULTS: No trials evaluating the effectiveness of tonsillectomy in adults were identified. Two trials from Pittsburgh assessed tonsillectomy in children. Significant baseline differences between the surgical and non-surgical groups and the inclusion of children who also underwent adenoidectomy prevent firm conclusions being drawn from the fully published trial. Limited and insufficient information is available from the second study; further details are awaited. REVIEWER'S CONCLUSIONS: The effectiveness of tonsillectomy has not been formally evaluated. Further trials addressing relevant outcome measure are required.

Serum and mucosal antibody responses to pneumococcal protein antigens in children: relationships with carriage status.

Streptococcus pneumoniae causes significant morbidity and mortality especially in children. Some pneumococcal protein antigens can protect mice against infection. Little information is available concerning the nature of naturally acquired protective immunity to pneumococci in humans induced by these antigens. This study investigates the relationships between systemic and local antibody production and carriage in children. Children undergoing adenoidectomy (n=112, ages 2-12 years) were studied. Nasopharyngeal swabs were collected for pneumococcal culture. Serum and saliva were assayed for antibodies to several pneumococcal proteins: choline binding protein A (CbpA), pneumolysin (Ply), pneumococcal surface adhesin A (PsaA) and pneumococcal surface protein A (PspA). Adenoidal mononuclear cells (MNC) were cultured with pneumococcal culture supernatants or recombinant proteins. Cell culture supernatants were analyzed for antigen-specific antibodies. Carriage rates fell with age and serum levels of anti-CbpA, Ply and PspA rose. Anti-CbpA and -Ply serum and salivary IgG antibody levels were higher in children who were culture negative than those who were colonized. Antigen stimulation increased respective antigen-specific IgG production by adenoidal MNC and these responses were greater in those who were colonized than in culture-negative children. Antibodies to CbpA and Ply may protect children aged 2 years and older against pneumococcal colonization. Adenoids may be important local induction and effector sites for both mucosal and systemic antibody production to pneumococcal proteins in children.

Post-tonsillectomy hemorrhage: incidence, prevention and management.

Tonsillectomy (with or without adenoidectomy) continues to be a commonly performed operation in the United States. Over the years, the incidence of post-tonsillectomy hemorrhage (reported between 0% and 20%) has decreased, but continues to pose serious problems. We reviewed 1,445 tonsillectomies performed over a 2-year period to study the incidence of post-tonsillectomy hemorrhage. Thirty-eight of 1,445 children (2.62%) had postoperative bleeding. The incidence of primary hemorrhage (within 24 hours) was 0.14%. Delayed hemorrhage requiring operative intervention or observation in the hospital was 1.03% and 0.76%, respectively. Ten patients (0.69%) had delayed hemorrhage of a minor nature that had stopped by the time they reached the hospital; these children were treated with observation alone and did not require hospitalization or operative intervention. The proposed reasons for this low rate of post-tonsillectomy hemorrhage include complete preoperative coagulation screening, meticulous attention to surgical technique, use of suction-cautery to obtain hemostasis and, possibly, use of postoperative antibiotics. Management of hemorrhage is discussed with respect to observation, surgical intervention, and blood transfusion.
