RESUMO

INTRODUCTION: Despite the presence of a growing body of literature suggesting cost-ineffectiveness of routine pathologic analysis of tonsillectomy specimens, little is known about common institutional policies and practice patterns of pediatric otolaryngologists. The objectives of this study were to determine the prevalence of routine pathological evaluation of tonsillectomy specimens for uncomplicated pediatric adenotonsillectomy procedures and to evaluate opinions regarding this controversy among board-certified pediatric otolaryngologists. METHODS: This was a cross-sectional survey study sent to board-certified pediatric otolaryngologists currently practicing and registered with the American Society of Pediatric Otolaryngology (ASPO) assessing their institutions' or practices' current policies on sending routine tonsillectomy specimens for pathology, their experience with this practice, and their opinions on whether routine pathologic analysis should be employed. Basic statistical analysis was then conducted. RESULTS: Respondents mostly practiced in an academic setting (68.4%), with the next most common being academically affiliated private practice (21.8%), and private practice was the least common (9.8%). Most respondents (85.1%) did not agree with routine pathologic analysis of otherwise uncomplicated pediatric tonsillectomy specimens. CONCLUSION: Most pediatric otolaryngologists who responded to this survey do not support routine pathological analysis of otherwise uncomplicated pediatric tonsillectomy specimens. However, the results are likely biased and should be interpreted carefully, since only a small percentage of pediatric otolaryngologists responded to the survey. Potential cost savings could be seen by patients, payers, and hospital systems with judicious use of surgical pathology, specifically in cases with concurrent signs or symptoms suspicious for malignancy.

RESUMO

Choanal atresia is a rare congenital airway malformation that presents a unique surgical challenge for pediatric otolaryngologists. Here we report two classic cases of choanal atresia and examine the surgical approaches to this entity. The first case was a four-day-old female with a history of CHARGE syndrome and bilateral mixed membranous and bony choanal atresia confirmed by a CT scan. After undergoing transnasal endoscopic repair, choanal stents were placed for four weeks, and the patient was seen three months postoperatively and found to be doing well with no respiratory concerns. The second case involved a healthy three-year-old female presenting with unilateral combined membranous and bony atresia. Following successful endoscopic repair, she was seen at a three-month follow-up with no signs of restenosis. Additionally, a literature review was performed to evaluate updates since the 2012 Cochrane Review on surgical treatment of congenital choanal atresia.

RESUMO

Objective: To investigate the popular social media platforms Instagram and Facebook for public posts related to tympanostomy tubes in children, to discern attitudes and perceptions surrounding tympanostomy tubes, and to evaluate the content of social media posts related to tympanostomy tubes. Study Design: Qualitative study. Setting: Instagram and Facebook social media platforms. Methods: Instagram and Facebook were searched for public posts from 2018 and 2019 including the search terms "ear tubes,""ear tube surgery,""tympanostomy," and "myringotomy." Posts were excluded if they were unrelated to pediatric tympanostomy tubes or written in a non-English language. Relevant posts underwent subgroup analysis based on 6 domains: media type, perspective, topic, timeframe, popularity, and overall tone. Results: Of 1862 public social media posts, the majority (78.2%) were made by the patient's parents/caregivers and the rest by physicians (6.0%), hospitals (8.2%), and chiropractors (6.1%), with a few posts by the patients themselves (0.4%). The majority (79.3%) of posts portrayed tympanostomy tubes positively. Most negative posts were made by chiropractors (50.8%) and the patient's parents/caregivers (42.9%). The most common themes of posts were reassurance regarding surgery (74.9%), advertisements (12.5%), apprehension (12.4%), and education (10.3%). Conclusion: Most social media posts were made by parents/caregivers in the perioperative period, and there was a low percentage of educational posts. This information could be used by otolaryngologists to optimize their interactions with patients and parents and to potentially increase physician involvement and educational material related to tympanostomy tubes on social media.

RESUMO

Pilomatricomas are benign skin tumors often encountered by otolaryngologists but frequently misdiagnosed. Although they can occur at any age, they commonly present in children as a discolored superficial lesion adhered to the overlying skin. Accurate preoperative diagnosis is crucial for appropriate management, which is surgical in most cases. Here, we present bilateral pilomatricomas mimicking features of several other diagnoses in a pediatric patient. The patient was successfully treated with surgical excision. This case presented a unique diagnostic challenge, as the lesions exhibited features of several common diagnoses. In general, surgical management of pilomatricoma is curative, and recurrence is rare.

RESUMO

OBJECTIVES: To determine predictors of obstructive sleep apnea (OSA) in underweight children and to describe the demographic, clinical, and polysomnographic characteristics of an ethnically diverse population of underweight children with OSA. STUDY DESIGN: Case-control study. SETTING: University of Texas Southwestern Medical Center and Children's Medical Center of Dallas. METHODS: Underweight children aged 2 to 18 years who underwent a polysomnogram for suspected OSA between January 2014 and December 2020 were included. Underweight was defined as body mass index <5th percentile per Centers for Disease Control and Prevention guidelines. Children with apnea-hypopnea index <1.0 served as a control group. Univariate and multiple logistic regression analysis was used to determine the predictors of OSA. Significance was set at P < .05. RESULTS: An overall 124 children met inclusion criteria: mean age, 6.4 years; 50% female; 44% Hispanic, 31% African American, and 18% Caucasian. A total of 83 children had OSA (apnea-hypopnea index ≥1.0). Height was negatively correlated with OSA (odds ratio, 0.94; 95% CI, 0.88-0.99; P = .02) while allergic rhinitis (odds ratio, 2.97; 95% CI, 1.24-7.08; P = .01) and tonsillar hypertrophy (odds ratio, 3.38; 95% CI, 1.42-8.02; P = .01) were predictors for the presence of OSA. No demographic or clinical characteristics were predictors for severe OSA. CONCLUSION: Underweight children with OSA, as compared with those without OSA, are more likely to have decreased height, tonsillar hypertrophy, and allergic rhinitis. There are no predictors of severe OSA in underweight children. We recommend polysomnography for the diagnosis of OSA in symptomatic underweight children with large tonsils, especially when they have a history of allergies.

RESUMO

INTRODUCTION: Despite the presence of clinical practice guidelines for overnight admission of pediatric patients following adenotonsillectomy, variance in practice patterns exists between pediatric otolaryngologists. The purpose of this study is to examine severity of apnea-hypopnea index (AHI) as an independent predictor of postoperative respiratory complications in children undergoing adenotonsillectomy. METHODS: Retrospective chart review of all children undergoing adenotonsillectomy at a large tertiary referral center between January 2015 and December 2019 who underwent preoperative polysomnography and were admitted for overnight observation. Charts were reviewed for total adverse events and respiratory events occurring during admission. RESULTS: Overall, respiratory events were seen in 50.6% of patients with AHI ≥10 and in 39.6% of patients with AHI <10. The overall mean AHI was 19.2, with a mean of 28.1 in the AHI ≥10 subgroup vs 4.6 in the AHI <10 subgroup. There was no statistical correlation or increased risk between an AHI ≥10 and having a pure respiratory event, with a relative risk of 1.19 (.77-1.83, P = .43). There was a statistically significant difference between the mean AHI of those with any adverse event and those without (21.6 vs 13.4, P = .008). There is additionally an increased risk of any event with an AHI over 10, with a relative risk of 1.51 (1.22-1.88, P < .0001). CONCLUSION: Preoperative AHI of 10 events per hour was not a predictor of postoperative respiratory complications. However, there was a trend for those with a higher AHI requiring additional supportive measures or a prolonged stay. Practitioners should always use their best judgment in deciding whether a child warrants postoperative admission following adenotonsillectomy.

RESUMO

OBJECTIVES: Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of neonatal respiratory distress that is difficult to treat. The primary objective of this study was to identify factors that predict the need for initial and revision surgery for CNAPS. The secondary objective is to identify risk factors in maternal history associated with the development of CNPAS. METHODS: Infants with CNPAS between 2010 and 2017 were identified by ICD- 9 and 10 codes. Demographics, maternal history, anatomic features on imaging and medical and/or surgical management were reviewed. Frequencies, means and standard deviations were calculated. A p-value <.05 was considered significant. RESULTS: Twenty infants were included. All underwent flexible nasal endoscopy with inability to pass the scope in either nostril in 65% of infants. Nineteen had a CT scan and 13 had a MRI with midline defects in 76.3% and 53.8%, respectively. Solitary central mega-incisor was present in 65%. Half underwent surgical intervention at a mean age of 74.8 days, with 90% requiring revision surgery. There was no difference in pyriform aperture distance in the surgical and non-surgical patient subgroups (5.4 mm and 5.2 mm, p = .6 respectively). No specific variables were predictive of need for initial or revision surgery. Maternal diabetes mellitus (MDM) was found in 55% of mothers of infants with CNPAS. CONCLUSION: Pyriform aperture distance was not a predictor of surgical intervention. MRI should be considered in all infants with CNPAS as the rate of intracranial complications is high. MDM may be a risk factor for CNPAS.

RESUMO

Staphylococcus aureus is the most common causative organism in pediatric septic arthritis, with methicillin-resistant Staphylococcus aureus (MRSA) being responsible for a significant portion of these infections. Early identification and initiation of proper treatment may improve outcomes by minimizing potential morbidity. The purpose of this study was to identify variables obtained on initial patient presentation associated with MRSA septic arthritis. Sixteen factors were retrospectively evaluated in 109 consecutive pediatric patients diagnosed with culture-confirmed septic arthritis. Graphical and logistical regression analyses were employed to determine factors independently predictive of MRSA septic arthritis. Twenty-seven (25%) patients had MRSA and 82 (75%) had non-MRSA septic arthritis. C-reactive protein of 13.7 mg/L or greater, duration of symptoms of 4 days or more, heart rate of 126 beats per minute or greater, and absolute neutrophil count of 8.72×103 cells/µL or greater were associated with MRSA septic arthritis. Ultimately, 98% of patients with 1 or no risk factors had non-MRSA and 96% of patients with MRSA septic arthritis had 2 or more positive risk factors. Elevated C-reactive protein, duration of symptoms, heart rate, and absolute neutrophil count are predictive of MRSA infection in the setting of pediatric septic arthritis and can be obtained on initial evaluation. In patients for whom there is concern for MRSA infection, this may guide more expedient treatment, such as early initiation of contact precautions and appropriate antibiotic therapy before culture results become available.

RESUMO

OBJECTIVE: Epidermoid cysts are rarely located in the uvula. To date, epidermoid cyst of the uvula has not been reported in a child at preschool age. We present clinical and histopathological characteristics of an epidermoid cyst in a child with uvula mass. METHODS: Retrospective chart review. RESULTS: A 5-year-old boy was seen in the pediatric otolaryngology clinic for assessment of a uvula mass. The mass was detected during a tonsillectomy and adenoidectomy performed for sleep-related breathing disorder. The mass was completely removed and the final diagnosis was epidermoid cyst. CONCLUSION: Pediatricians, otolaryngologists, and pathologists should be cognizant of the occurrence of uvular epidermoid cyst in preschool children.

RESUMO

Reconstruction of head and neck defects after cancer resection involves the use of local, pedicled musculocutaneous, and free flaps. Flap failure is often caused by vascular insufficiency, and it is associated with the presence of cardiovascular or peripheral vascular disease, a history of smoking, and previous radiation and/or surgery. Failure rates may be reduced by the use of indocyanine green near-infrared fluorescence laser angiography, which detects perfusion deficits intraoperatively. Although this technology has been validated in other fields, there is limited experience in the head and neck region. We present 3 cases in which different head and neck flaps were used along with this technology in patients at high risk for flap failure. All flaps were successfully implanted without perioperative or long-term complications. The increasing complexity, age, and comorbidities of the head and neck cancer population pose significant reconstructive challenges. This report demonstrates the feasibility of employing intraoperative angiography for local, pedicled, and free flaps. This noninvasive tool optimizes intraoperative planning and assesses viability, potentially lowering failure rates in high-risk patients. Identification of patients who most benefit from this technology warrants further investigation.

RESUMO

BACKGROUND: Mesenchymal malignancies of salivary origin are rare and are histologically diverse. We reviewed our experience with these tumors, as well as the published literature, with an emphasis on treatment modalities and prognosis. METHODS: We identified 17 patients treated for malignant mesenchymal cell tumors at The University of Texas MD Anderson Cancer Center between 1990 and 2007. We compared our results to the literature from January 1990 to July 2010. RESULTS: Tumors were located primarily in the parotid gland and were primarily T1 tumors (<5 cm). All patients were treated with surgical resection, and 13 patients were given adjuvant therapy. Seven patients (41%) had recurrence, and 4 developed distant metastases. The overall 5-year and 10-year survival rates were 42% and 20%, respectively. CONCLUSIONS: Our case series and literature review show that sarcomas of the salivary glands have a high rate of recurrence and are associated with a poor prognosis.

RESUMO

OBJECTIVE: Local vancomycin treatment has been shown to decrease sternal wound complication rates. Whether a similar effect can be achieved at other surgical sites is unknown. This study investigates the effect of local vancomycin on inguinal wound complication rates after vascular procedures. METHODS: Retrospective analysis was performed on 454 patients who underwent open aortofemoral or infrainguinal vascular procedures between 2006 and 2011. Patients received preoperative systemic antibiotics either alone (group A) or in conjunction with intraoperative wound application of vancomycin powder and irrigation (group B). Inguinal wound infection and dehiscence over a 30-day period were recorded. Fisher exact test and multivariate regression analyses were performed. RESULTS: There were 211 patients in group A and 243 patients in group B. Both groups had similar demographics and operative characteristics. There was a small but statistically significant decrease in the 30-day incidence of overall wound infections (25.1% vs 17.2%; P = .049) for group B patients. This was primarily due to a decreased rate in superficial infections (18.9% vs 11.5%; P = .033). No significant difference in the incidence of deep wound infections (6.1% vs 5.7%; P = .692) or overall dehiscence rates (22.2% vs 17.7%; P = .239) was detected. On multivariate analysis, history of chronic obstructive pulmonary disease and increased body mass index significantly increased risk of both infection and dehiscence. Medically optimized coronary artery disease was associated with less risk for dehiscence. CONCLUSIONS: Addition of intraoperative local vancomycin did not improve the rates of inguinal wound dehiscence or deep infections but had a positive impact on superficial wound infections.

RESUMO

BACKGROUND: Oropharyngeal squamous cell carcinoma (OPSCC) is increasing in frequency. We reviewed patients with advanced-stage OPSCC treated with chemoradiation to assess the impact of residual neck disease on survival. METHODS: We reviewed 202 patients with OPSCC between 1990 and 2010 treated with primary chemoradiation followed by neck dissection. Imaging was analyzed using RECIST (Response Evaluation Criteria In Solid Tumors) 1.1 criteria. Survival was evaluated using both univariate and multivariate analyses. RESULTS: Overall survival at 5 years was 89%. Forty-two patients (21%) had residual disease in the neck (pN+). pN+ was associated with greater locoregional recurrence (LRR) and distant metastasis (DM) and decreased survival. No clinicopathologic factors were predictive of pN+. Contrasted posttreatment CT had low sensitivity and specificity. CONCLUSIONS: In advanced OPSCC pN+, patients have higher rates of LRR and DM. Neither clinicopathologic factors nor posttreatment imaging was predictive of pN+, although increased use of modern imaging may reduce the rate of negative neck dissections.

RESUMO

Amphiphilic block copolymers are finding increased potential in biological and medical research due to their innate alternating hydrophilic and hydrophilic blocks/segments which can be used to package therapeutics, or coat a broad array of biological interfaces. Some studies are already directed towards utilizing these copolymers' ability to form micelles or vesicles to develop novel methods of drug delivery to prevent inflammation or pro-cancer activity. Our study, however, aims to investigate the more fundamental cell-block copolymer interaction for use in protective nanofilms to prevent bio-fouling of non-tissue based implantable devices. Block copolymers could potentially fill the demand for biologically inert, highly functionalizable biomaterials desirable for this type of application. Two such polymers used in our study include PMOXA-PDMS-PMOXA triblock copolymer and PEO/PMMA diblock copolymer. Each block copolymer possesses hydrophilic and hydrophobic blocks that enable it to mimic the cell lipid membrane. So far we have shown that triblock copolymer is capable of inhibiting the accumulation of murine macrophages onto glass substrates. Preliminary evidence has suggested that the triblock copolymer has anti-adsorptive as well as non-inflammatory capabilities during short incubation periods (7 days) in vitro. While the diblock copolymer displays minimal anti-adsorptive activities, nanofilms comprised of a mixture of the two copolymers were able to significantly reduce macrophage accumulation onto glass substrates. The disparate behavior seen by macrophages on the different materials may be due to specific inherent properties such as preference for hydrophobic vs. hydrophilic surfaces and/or rough vs. smooth nano-textures. Furthermore, the specific end groups of the two polymers may exhibit varying capacities to resisting non-specific protein adsorption. Continued investigation outlining the physical and chemical properties desirable for an anti-adsorptive nano-film coating will serve as a basis upon which to design durable implant-tissue interfaces that can react to various external stimuli.
