Multi-institutional Assessment of Otitis Media Epidemiology Using Real-world Data.

OBJECTIVES: To determine rates and risk factors of pediatric otitis media (OM) using real-world electronic health record (PEDSnet) data from January 2009 through May 2021. STUDY DESIGN: Retrospective cohort study. SETTING: Seven pediatric academic health systems that participate in PEDSnet. METHODS: Children <6 months-old at time of first outpatient, Emergency Department, or inpatient visit were included and followed longitudinally. A time-to-event analysis was performed using a Cox proportional hazards model to estimate hazard ratios for OM incidence based on sociodemographic factors and specific health conditions. RESULTS: The PEDSnet cohort included 910,265 children, 54.3% male, mean age (months) 1.3 [standard deviation (SD) 1.6] and mean follow up (years) 4.3 (SD 3.2). By age 3 years, 39.6% of children had evidence of one OM episode. OM rates decreased following pneumococcal-13 vaccination (PCV-13) and the COVID-19 pandemic. Along with young age, non-Hispanic Black/African American or Hispanic race/ethnicity, public insurance, higher family income, and male sex had higher incidence rates. Health conditions that increased OM risk included cleft palate [adjusted hazard ratio (aHR) 4.0 [95% confidence interval (CI) 3.9-4.2], primary ciliary dyskinesia [aHR 2.5 (95% CI 1.8-3.5)], trisomy 21 [aHR 2.0 (95% CI 1.9-2.1)], atopic dermatitis [aHR 1.4 (95% CI 1.4-1.4)], and gastroesophageal reflux [aHR1.5 (95% CI 1.5-1.5)]. CONCLUSIONS: Approximately 20% of children by age 1 and 40% of children by age 3 years will have experienced an OM episode. OM rates decreased after PCV-13 and COVID-19. Children with abnormal ciliary function or craniofacial conditions, specifically cleft palate, carry the highest risk of OM.

Cortical Auditory Evoked Potential Testing in Children With Auditory Neuropathy Spectrum Disorder.

PURPOSE: In the present report, we reviewed the role of cortical auditory evoked potentials (CAEPs) as an objective measure during the evaluation and management process in children with auditory neuropathy spectrum disorder (ANSD). METHOD: We reviewed the results of CAEP recordings in 66 patients with ANSD aged between 2 months and 12 years and assessed the relationship between their characteristics (prevalence, morphology, latencies, and amplitudes) and various clinical features, including the mode of medical management. RESULTS: Overall, the CAEPs were present in 85.2% of the ears tested. Factors such as prematurity, medical complexity, neuronal issues, or presence of syndromes did not have an effect on the presence or absence of CAEPs. CAEP latencies were significantly shorter in ears with cochlear nerve deficiency than in ears with a normal caliber nerve. Three different patterns of CAEP responses were observed in patients with bilateral ANSD and present cochlear nerves: (a) responses with normal morphology and presence of both P1-P2complex and N2 components, (b) responses with abnormal morphology and presence of the N2 component but undefined P1-P2complex peak, and (c) entirely absent responses. None of the patients with normal, mild, or moderate degree of hearing loss had a complete absence of CAEP responses. No significant differences were uncovered when comparing the latencies across unaided and aided children and children who later received cochlear implants. CONCLUSIONS: The CAEP protocol used in our ANSD program did inform about the presence or absence of central auditory stimulation. Absent responses typically fit into an overall picture of complete auditory deprivation and all of these children were ultimately offered cochlear implants after failing to develop oral language. Present responses, on the other hand, were acknowledged as a sign of some degree of auditory stimulation but always interpreted with caution given that prognostic implications remain unclear.

A 15-year Review of 260 Children With Auditory Neuropathy Spectrum Disorder: II. Management and Outcomes.

OBJECTIVES: Following a review of the demographic and clinical characteristics of all pediatric patients diagnosed with auditory neuropathy spectrum disorder (ANSD) by a pediatric health care system from 2005 to 2020, the present report highlights the type and timing of intervention and outcomes in the same 260 patients with ANSD. DESIGN: This was a retrospective study reviewing the demographic data, medical history, imaging studies, audiological and speech language data, type of audiological intervention (hearing aids or cochlear implants), and mode of communication in 260 pediatric patients diagnosed with ANSD over a 15-year period. RESULTS: A significant decrease over time in the age at hearing aid fitting was observed. While a similar reduction in the age at implantation occurred over time, cochlear implantation is still rarely performed by 12 months of age in most ANSD patients. Among bilateral ANSD patients fitted with hearing aids, the majority (89.2%) did not benefit from conventional amplification and most received cochlear implants. Some hearing aid benefit for speech and language development was observed in 5.8%, though communication difficulties were persistent and most used a combination of oral and sign language for communication. Only six patients (5%) received significant benefit from their hearing aids for speech and language development. CONCLUSIONS: This review of ANSD management over a 15-year period reveals that hearing aids are not a viable option to develop speech and language for most infants and children with ANSD. This finding confirms previous reports and suggest that while hearing aid trials are warranted, children must be tracked closely so as to avoid delays in decision making. Cochlear implantation constitutes the major (if not only) rehabilitative intervention that allows for speech perception in patients who do not benefit from conventional amplification.

A 15-Year Review of 260 Children With Auditory Neuropathy Spectrum Disorder: I. Demographic and Diagnostic Characteristics.

OBJECTIVES: The aim of the study was to review the demographic and clinical characteristics of all pediatric patients diagnosed with auditory neuropathy spectrum disorder (ANSD) by a pediatric health care system from 2005 to 2020 and examine whether or not our diagnostic capabilities in an ANSD population have evolved as our institutional experience has grown and knowledge in the field has expanded. DESIGN: This was a retrospective study reviewing the demographic data, medical history, imaging studies, audiological and speech-language data, type of audiological intervention and mode of communication in 260 pediatric patients diagnosed with ANSD over a 15-year period. RESULTS: The study revealed that male and female children were equally affected with all levels of hearing detection being represented and that about 40% of affected children were premature and most were admitted to the neonatal intensive care unit. More than a third of our patients presented with a complex medical history and/or neural involvement while about 30% were full-term newborns with normal pregnancy, no prenatal complications or infections, normal birth weight, no neonatal intensive care unit need, no hyperbilirubinemia, no respiratory distress requiring ventilation, and no known syndrome. Review of audiological findings confirms that otoacoustic emissions are not always present in ANSD cases, and that the presence of an abnormal wave V on the auditory brainstem response tracings (only present at high intensities and with an absent intensity/latency function) is not a rare finding and should not immediately be dismissed as not being a case of ANSD. CONCLUSIONS: This review of ANSD diagnosis over a 15-year period clearly reveals the drastic improvements made in the identification of ANSD, with a drastic decrease in the age at diagnosis and a reduction in the percentage of misdiagnosed patients. The study also stresses the need for continued improvement in different areas such as genetic studies and physiological measures to help clinicians distinguish between pre- and postsynaptic ANSD.

Hearing outcomes in children with Congenital Cytomegalovirus: A multi-center, single-enterprise experience.

BACKGROUND: Cytomegalovirus (CMV) is the most common cause of non-genetic sensorineural hearing loss (SNHL) in the United States; yet screening for congenital CMV (cCMV) remains controversial. CMV related SNHL can be present at birth, or develop in a delayed manner, and it is a consistent feature in children with either symptomatic or asymptomatic disease. A retrospective chart review was performed to determine the characteristics of patients diagnosed with cCMV and SNHL. METHODS: The electronic database warehouse of the Nemours Children's Health System (NCHS) was queried from 01/01/2004 to 10/05/2019. ICD 9 (771.1) and ICD 10 (B25.9, P35.1) diagnostic codes were used to identify patients throughout the system with a diagnosis of cCMV infection. Patient demographics including gender, race/ethnicity, age of diagnosis, results of newborn hearing screening (NBHS), detection and progression of hearing loss, presence of antiviral therapy, and frequency of monitoring were collected, and descriptive statistics performed. RESULTS: Of the 170 patients confirmed to have cCMV, 153 (90%) were symptomatic and 17 (10%) were asymptomatic. CNS involvement (63.5%), radiographic evidence of disease present (69.4%), and SNHL (50.6%) were the most common manifestations of the disease. Of these 170 patients, 83 (48.8%) were determined to have SNHL eligible for evaluation. For these patients with SNHL, the average time of hearing monitoring was 50.6 months. At the time of initial reported detection 63 of 83 (76%) had bilateral hearing loss and 20 (24%) had unilateral loss. Over the study period 3 (15%) progressed from unilateral to bilateral involvement, and 32 (47%) had a deterioration in hearing, with severe to profound SNHL in at least one ear identified at the last visit in 53 (64%) patients. Newborn hearing testing results were available for 69 (83%) of those with hearing loss and 26 patients passed initial testing. However, of the 26 patients who passed, 22 (85%) eventually developed SNHL by their last visit. Within our cohort, females with cCMV were significantly more likely to have SNHL than males with cCMV (62.3% versus 37.6%; p < 0.01). CONCLUSION: In the absence of targeted or universal cCMV screening, the majority of children identified with this condition present symptomatically. Approximately one half of children with symptomatic cCMV failed NBHS at birth while at least 25% develop SNHL later in life. Children with cCMV are at high risk of delayed onset loss and such children, particularly females, should be monitored closely.

Racial disparities in pediatric otolaryngology: current state and future hope.

PURPOSE OF REVIEW: The current article reviews the current literature and selected sentinel papers on health disparities particularly relevant to the field of pediatric otolaryngology. The discussion will explore racial disparities in otologic and airway intervention areas, as well as general adenotonsillar disease management. Access to and quality of care will be examined, and disparate outcomes discussed. RECENT FINDINGS: Growing published data demonstrate children from nonwhite backgrounds receive disparate specialty care in representative fields of pediatric otolaryngology. SUMMARY: Racial disparities exist in specialty care pediatric otolaryngology. Such disparities should be viewed in the light of generational inequalities in the United States and the foundational inequities that perpetuate them. Parity in the delivery of such specialty care depends on recognizing our current state and intentional efforts to modulate the impact of such effectual factors.

Racial and Insurance Inequalities in Access to Early Pediatric Cochlear Implantation.

OBJECTIVE: To evaluate the association between race/ethnicity and insurance status on the access to early cochlear implantation. STUDY DESIGN: Population-based retrospective analysis of pediatric cochlear implantation procedures. SETTING: State Ambulatory Surgery and Services Databases of Florida from 2005 to 2017. METHODS: All children aged 18 years or younger in the state of Florida undergoing cochlear implantation were identified. The outcome measures were access to early cochlear implantation (before 1 and 2 years of age). Descriptive and multivariate logistic regression analyses were conducted. RESULTS: Among 1511 pediatric cochlear implantation procedures with complete data, 65 (4.3%) procedures were performed by 1 year of age and 348 (23.0%) by 2 years of age. Black children (odds ratio [OR], 0.44; 95% CI, 0.28-0.70), Hispanic children (OR, 0.70; 95% CI, 0.52-0.94), and children with Medicaid (OR, 0.64; 95% CI, 0.48-0.84) were significantly less likely to be implanted before 2 years of age. Even when insured by private insurance, black and Hispanic children were still less likely to be implanted before 2 years of age compared to white children with private insurance. Greater racial and insurance disparities existed in access to cochlear implantation before 1 year of age compared to implantation before 2 years of age. CONCLUSION: Racial/ethnic and insurance disparities in pediatric cochlear implantation can be observed at the population level. To address these racial and insurance inequalities, a multidisciplinary care team is needed and priorities should be given to research endeavors and policy interventions that target these disparities.

Transcutaneous Osseointegrated Implants for Pediatric Patients With Aural Atresia.

Importance: Patients with aural atresia typically have maximal conductive hearing loss, which can have negative academic and social consequences. Transcutaneous osseointegrated implants (TOIs) can potentially restore hearing on the affected side. Objectives: To review the demographic, audiological, and surgical outcomes of TOI placement in pediatric patients with aural atresia and to describe a modification in incision technique in anticipation of later auricular reconstruction. Design, Setting, and Participants: This retrospective case series reviewed 41 cases of TOI placement in pediatric patients between January 1, 2014, and September 30, 2016, at Lurie Children's Microtia and Aural Atresia Clinic. Patients, all younger than 18 years and with atresia or microtia, received at least 6 months of follow-up and underwent testing before and after surgery. Main Outcomes and Measures: Patient age, indication for procedure, ear sidedness, case length, incision type, complications, and other postoperative events. Audiological outcomes before and after implantation were measured using pure-tone averages and the Hearing In Noise Test for Children, presented in variable signal to noise ratios. Results: In total, 46 TOIs were performed in 38 pediatric patients, but only 41 implantations in 34 patients were included in this study. Of the 34 patients, 13 (38%) were males and 21 (62%) were females, with a mean age of 8.9 (range, 5-17) years at the time of TOI placement. Microtia on the implanted side was present in 39 cases (95%). A modified posterior-superior scalp incision technique was used in 30 (73%) of 41 ears, all in cases of microtia. One perioperative surgical complication occurred: a seroma requiring drainage. Two patients developed minor skin irritation and erythema at the magnet site related to the overnight use of the processor, which resolved when removed while sleeping. The mean (SD; range) score for the Speech In Noise test at 5 dB signal to noise ratio improved from 75.3% (14.4%; range, 50%-92%) correct in unaided/preoperative condition to 93.6% (6.95%; range, 80%-100%) correct in the aided/postoperative condition. The mean improvement in score was 18.3% (95% CI, 10.8%-25.9%), with an effect size of 1.62 (95% CI, 0.95-2.29). The mean pure-tone averages (SD; range) similarly improved from 63.7 (13.2; range, 25-11) dB to 9.6 (4.9; range, 5-15) dB. Conclusions and Relevance: Transcutaneous osseointegrated implantation has a low complication rate among pediatric patients with atresia or microtia and can provide excellent audiological results. It should be included as a treatment option for this population of patients who meet audiological criteria.

Inpatient Nursing and Parental Comfort in Managing Pediatric Tracheostomy Care and Emergencies.

IMPORTANCE: Tracheostomy is a critical and often life-saving intervention, but associated risks are not negligible. The vulnerability of the pediatric population underlies the importance of caregiver comfort and competence in tracheostomy care. OBJECTIVE: To assess inpatient nursing staff and parental perspectives in managing tracheostomy care. DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional analysis of survey data from (1) a volunteer sample of inpatient nurses in a tertiary care, freestanding pediatric hospital in the Midwest, assigned to clinical wards that provide care for children with tracheostomy tubes and (2) a consecutive sample of families whose child underwent tracheostomy tube placement at the same institution between March 1 and December 31, 2013. MAIN OUTCOMES AND MEASURES: Nurse and parental comfort in managing acute and established tracheostomy tubes. Nursing data were analyzed with attention to years' experience and primary unit of practice. RESULTS: Respondents included 129 of 820 nurses (16% response rate) and family members of 19 of 38 children (50% response rate). When queried about changing established tracheostomies, 59 of 128 nurses (46%) reported being "totally comfortable," including 46 of 82 intensive care unit (ICU) nurses (56%) vs 13 of 46 floor nurses (28%) (P = .002) and 48 of 80 nurses with at least 5 years' experience (60%) vs 12 of 49 less experienced nurses (24%) (P < .001). For managing accidental decannulation of a fresh tracheostomy, 61 nurses (47%) described being completely uncomfortable, including 27 of 83 ICU nurses (33%) vs 34 of 46 floor nurses (73%) (P = .006), and 33 of 80 nurses with at least 5 years' experience (41% ) vs 28 of 49 less experienced nurses (57%) (P = .03). Most families felt prepared for discharge (16 of 17 [94%]) and found the health care team accessible (16 of 17 [94%]), although only 5 of 18 families (28%) indicated that tracheostomy teaching was consistent. CONCLUSIONS AND RELEVANCE: Nurses' comfort with tracheostomy was higher among nurses with at least 5 years' experience and primary ICU location. Whereas parental comfort with tracheostomy care was high, lack of consistent instruction highlights the role for standardized education in tracheostomy care.

Dermoid of the oral cavity: case report with histopathology correlation and review of literature.

Dermoid cysts are rare masses of the oral cavity derived from ectodermal elements. These are benign, slow-growing tumors that are typically asymptomatic but cause complications of inflammation or dysphagia, dystonia, and airway encroachment due to mass effects. We report the case of a 17 year old female with a painless mass in the left side of the oral cavity. Ultrasound findings demonstrated non-specific findings of a cystic lesion, and definite diagnosis was made with contrast-enhanced CT and intraoperatively with pathologic confirmation. This retrospective report highlights the challenges in evaluating masses of the oral cavity with imaging and provides a comprehensive discussion on imaging of oral masses on various imaging modalities to guide diagnosis and management.

Raeder syndrome: Paratrigeminal oculosympathetic syndrome presenting as a manifestation of chronic sinusitis.

Raeder syndrome (paratrigeminal oculosympathetic syndrome) is a rare clinical entity characterized by ipsilateral trigeminal sensory deficits, ptosis, and miosis, with an absence of anhidrosis secondary to interruption of the postganglionic oculosympathetic pathway. Going back to its original description, this constellation of physical examination findings has historically been associated with intracranial pathology involving the middle cranial fossa. Understanding this pathway is important in distinguishing Raeder syndrome from Horner syndrome, as the presentation of the former is now recognized to accompany a number of other disease entities in the head and neck region. We present an unusual case of Raeder syndrome associated with bacterial sinusitis, and we discuss its management and review the literature.

Trends in the management of pediatric peritonsillar abscess infections in the U.S., 2000-2009.

OBJECTIVES: To analyze temporal trends in the incidence and surgical management of children with peritonsillar abscesses (PTAs), and to examine whether there has been concurrent changes in hospital charges or length of stay. METHODS: The Kids' Inpatient Database (KID) from 2000 to 2009 was examined for children less than 18 years old with ICD-9-CM diagnostic codes for PTA (475). Survey weighted frequency and regression analyses were performed across the entire study period on variables of interest in order to determine estimates of national incidence, demographics and outcomes. RESULTS: A total of 20,546 weighted cases of PTA were identified during the study period. There was no significant change in the incidence of pediatric PTA across the study period (p=0.63) or in the rate of nonsurgical management (p=0.85). There was a significant increase in the rates of I&D from 26.4% to 33.7% (p<0.001) and a significant decrease in the rate of tonsillectomy from 13.0% to 7.8% (p<0.001). Mean inflation-adjusted charges significantly increased from approximately $8400 in 2000 to $13,300 in 2009 (p<0.001), and average length of stay was 2.15 days with no significant change during the study period (p=0.164). Mean inflation-adjusted charges for patients undergoing tonsillectomy alone were approximately $1800 greater than mean charges for those undergoing I&D alone (p=0.003) and length of stay was also significantly longer for tonsillectomy patients versus I&D patients [I&D 1.99 days versus tonsillectomy 2.23 days (p<0.001)]. CONCLUSIONS: There was no change in the incidence of pediatric PTAs from 2000 to 2009 but there was a change in surgical management, with a significant decrease in the rate of tonsillectomy and significant increase in the rate of incision and drainage procedures. Hospital charges during this period increased nearly 60% despite no change in rates of CT imaging, surgical intervention or length of stay.

Variations in the cochlear implant experience in children with enlarged vestibular aqueduct.

OBJECTIVES/HYPOTHESIS: To describe the clinical experience and characterize the outcomes of cochlear implantation (CI) in children with isolated enlarged vestibular aqueduct (IEVA) as compared to children with enlarged vestibular aqueduct (EVA) associated with other bony labyrinth abnormalities. STUDY DESIGN: Single, tertiary care, institutional retrospective review over 2 decades. METHODS: The clinical course and outcomes of 55 children with EVA undergoing CI between 1991 and 2013 were reviewed. Test measures included open and closed set speech perception tests, and various speech and language measures. RESULTS: In 18 children (32.7%), IEVA was the only defect present. In 33 children (60%), EVA occurred concomitantly with incomplete partition type 2 (IP 2) bilaterally, and three children with incomplete partition type 1 bilaterally. Ninety-two percent (51 of 55) occurred bilaterally and had matching bony defects. Mean age of CI was 73.4 months. A statistically significant defect-related and linguistic-status pattern was noted, impacting the timing of implantation: IEVA = 112.8 months, IP 2 = 58.4 months (P < .001), prelingual deafness = 53.8 months, postlingual deafness = 110.8 months (P < .001). Controlling for implant age and hearing loss severity, IEVA children demonstrated superior performance on speech perception tests (8.2 to 20.3 point differences), though statistical significance was inconsistent (P = .01-.40. Performance was also superior in speech and language tests, though statistical significance was never reached (2.9-13.9 point differences; P = .14-.69). CONCLUSIONS: Children with hearing loss secondary to EVA respond meaningfully to cochlear implantation. However, the severity of temporal bone anomalies in these children has clinical relevance. LEVEL OF EVIDENCE: 4.

Surgical treatment of hearing loss when otosclerosis coexists with superior semicircular canal dehiscence syndrome.

OBJECTIVE: Document a case of bilateral otosclerosis with coexisting bilateral superior semicircular canal dehiscence syndrome and the treatment of hearing loss in this setting. PATIENT: A 33-year-old woman presented with bilateral mixed hearing loss; worse in the left ear. This was gradual in onset, and she denied dizziness. Computerized tomographic scan revealed fenestral otosclerosis and a large dehiscence of the superior semicircular canal bilaterally. She declined amplification. INTERVENTION: Sequential laser-assisted stapedotomy with insertion of a Kurz titanium CliP Piston prosthesis. MAIN OUTCOME MEASURE: Comparison of audiovestibular symptoms, hearing thresholds, and neurodiagnostic testing results preoperatively and postoperatively. RESULTS: Hearing improved bilaterally with closure of the air-bone gaps at most frequencies, and she has not had permanent vestibular symptoms. Postoperative follow-up time is 37 months for the left ear and 13 months for the right ear. CONCLUSION: When otosclerosis and superior semicircular canal dehiscence syndrome coexist and hearing loss is the dominant symptom, stapes surgery can be effective for improving hearing without permanent vestibular symptoms.

Pediatric deep space neck infections in U.S. children, 2000-2009.

OBJECTIVE: Deep space neck infections (DNI) are common pediatric illnesses, which can lead to significant morbidity and healthcare expenditures. Recent studies suggest that the incidence of pediatric DNI in the United States is increasing, but no nationally representative studies exist. This study sought to characterize pediatric DNI at the national level over the past decade and to determine whether U.S. incidence of pediatric DNI and associated resource utilization changed from 2000 to 2009. METHODS: The Kids' Inpatient Database (KID) was used to evaluate pediatric DNI incidence, demographics, and outcomes from 2000 to 2009. Cases were identified using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnostic codes for peritonsillar abscess (475), parapharyngeal abscess (478.22), and retropharyngeal abscess (478.24). Regression analyses within each year and across the entire study period were performed on variables of interest including performance of imaging studies, operative intervention, length of hospital stay and total hospital charges. RESULTS: The incidence of retropharyngeal abscess increased significantly from 0.10 cases per 10,000 in 2000 to 0.22 in 2009 (p=0.02). There was no significant change during this time period in the incidence of combined DNI (1.07-1.37 cases per 10,000, p=0.07), peritonsillar abscess (0.82-0.94 cases per 10,000, p=0.12) or parapharyngeal abscess (0.08-0.14 cases per 10,000, p=0.13). The percentage of retropharyngeal abscess patients managed surgically decreased (48-38%, p=0.04) and the average length of hospital stay also decreased during this time (4.6-3.9 days, p=0.03). There was a marked increase in the total inflation-corrected hospital charges per case for all DNI ($9,486-16,348, p=0.005). CONCLUSIONS: The incidence of pediatric retropharyngeal abscess has increased significantly from 2000 to 2009, without concurrent increases in the incidence of combined DNI, peritonsillar, or parapharyngeal abscesses. There has been a change in management of retropharyngeal abscesses during this time with a decrease in operative intervention and a decrease in the length of hospital stay. Hospital charges associated with all pediatric DNI have nearly doubled during this timeframe, warranting future epidemiologic resource utilization studies in this population.

Synchronous ipsilateral sebaceous lymphadenoma and membranous basal cell adenoma of the parotid.

A 46-year-old man presented with persistent right otalgia and hearing loss. Exam was significant for a mildly tender retromandibular mass with intact nonerythematous overlying skin. Computerized tomography with intravenous contrast of the neck revealed 2 relatively well circumscribed masses in the right parotid gland. Although 1 lesion was suspected to be a necrotic lymph node, histologic analysis after superficial parotidectomy demonstrated 2 unique salivary gland tumors. Diagnoses of both sebaceous lymphadenoma and membranous basal cell adenoma were rendered. The occurrence of unique, synchronous, ipsilateral salivary gland tumors is distinctly unusual and this combination of parotid gland neoplasms has not previously been documented. In this report, we present the case with its management, followed by a discussion of the histopathologic nature of each tumor including the possible overlap between these two entities.

Incidence of pediatric acute mastoiditis: 1997-2006.

OBJECTIVES: To evaluate the incidence of acute mastoiditis in children in the United States over the years 1997 through 2006 and to explore possible explanations for the conflicting conclusions of recent studies of this topic. DESIGN: Comparison of periodic incidence over a decade. SETTING: Academic and community, general, and pediatric specialty hospitals in the United States. PATIENTS: Children younger than 18 years in the United States treated and discharged with a diagnosis of acute mastoiditis during the years 1997 through 2006. MAIN OUTCOME MEASURES: To compare true incidence of acute mastoiditis in the pediatric population of the United States, data from Healthcare Costs and Utilization Project-Kids' Inpatient Database (HCUP-KID) was examined for nationally weighted estimates of hospital discharges, demographics (age and sex), hospital characteristics, and insurance characteristics. RESULTS: No significant change was found in the incidence of acute mastoiditis over the study period (from 1.88 to 1.62 per 100,000 person-years) (regression coefficient -0.024 [95% CI, -0.110 to 0.024]) (P = .37). Children admitted with acute mastoiditis had an increased odds of presenting to a teaching hospital (odds ratio [OR], 1.38 [95% CI, 1.31-1.45]) (P < .001), a children's hospital (OR, 1.08 [95% CI, 1.03-1.14]) (P = .001), and to a metropolitan location (OR, 1.10 [95% CI, 1.02-1.18]) (P = .016) over calendar time. CONCLUSIONS: The incidence of acute mastoiditis in the United States is not increasing. The changes in hospital factors identified over the course of this study may explain the perception of increased incidence identified in studies that have not used population-level data.

Legislating change in surgical residency.

The Patient Protection and Affordable Care Act, also known as the House of Representatives Bill HR 3590, was created to improve the quality of patient care and access to health care for American citizens. Provisions of this bill are likely to have both intended and unintended consequences on surgical education. The purpose of this article is to explore the ways in which HR 3590 may affect the educational experience of surgical house officers at teaching hospitals.

Management of acute appendicitis: the impact of CT scanning on the bottom line.

BACKGROUND: Acute appendicitis continues to be a common general surgical problem. Little is known about whether the contribution to margin has been affected by changes in technology. STUDY DESIGN: Patients undergoing appendectomy for acute appendicitis from June 2005 to May 2007 were evaluated for demographics, diagnostic and treatment alternatives, and outcomes. Financial outcomes were assessed. Efficiency, including admission to emergency department bed to incision (bed to knife time [BTK]), operative length, and hospital length of stay (LOS) were assessed. RESULTS: During the 2 years of the study, there were no differences in demographics, insurance status, case length, diagnostic accuracy, pathology, LOS, or outcomes. Both laparoscopy and CT use increased between the 2 study years (odds ratio [OR]: 1.68, p = 0.06; 95% CI, 0.98-2.89 and OR: 1.83, p = 0.06, CI, 0.98-3.45, respectively). Mean BTK time increased by about 1 hour: 465 minutes versus 521 minutes (p = 0.032; 95% CI, 0.08-1.78) in univariate analysis. However, multivariate analysis demonstrated no difference in BTK time between years (p = 0.136). After controlling for gender, year of operation, and insurance status, obtaining a CT study added 3.5 hours to BTK time (p < 0.001; 95% CI, 2.41-4.45). Women had BTK times 55 minutes longer than men when controlling for similar covariates (p = 0.027; 95% CI, 0.11-1.74). Laparoscopy contributed to shorter mean LOS (-0.78 days, p = 0.04), and gangrenous appendicitis (1.80 days, p < 0.001) and complications (4.23 days, p < 0.001) increased LOS. Mean contribution to margin decreased from $6,347 to $4,295 (p = 0.068). CONCLUSIONS: Increasing use of CT scanning in acute appendicitis increases cost of care, decreases contribution to margin, prolongs patient's stay in the emergency department, and delays time to operation.
