Acute pediatric tracheitis: Distinguishing the disease by tracheostomy status.

OBJECTIVES: Tracheitis is an upper airway infection that often presents in patients with tracheostomies and can potentially cause airway obstruction. This study aims to use a nationwide database to identify a large cohort of pediatric patients admitted with tracheitis to elucidate the management and resource utilization associated with the disease both with and without tracheostomies. METHODS: The Kids' Inpatient Database (KID) 2012 was used to identify 2394 weighted discharges with acute tracheitis, with or without obstruction, as the primary diagnosis. Data on prior tracheostomy status, demographics, hospital characteristics, management, and resource utilization were obtained. Two groups of interest, based on presence of prior tracheostomy, were studied. Linear regression was performed to determine independent predictors of total charges. RESULTS: The mean age was 5.52 years (SD: 5.54), mean length of stay (LOS) was 6.37 days (SD: 10.18), and mean total charges were $60,996.61 (SD: 107,798.41). Patients with prior tracheostomy had lower rates of endoscopy and endotracheal intubation than patients without (p < 0.0005). There was no significant difference in LOS (p = 0.076) or total charges (p = 0.210) between the groups based on prior tracheostomy status. CONCLUSION: Pediatric tracheitis should be differentiated on the basis of tracheostomy status. We propose that tracheitis diagnosis codes should be distinguished by the presence of tracheostomy as "open" and the absence of tracheostomy as "closed."

Predictors of occult lymph node metastasis in cutaneous head and neck melanoma.

OBJECTIVE: To use the Surveillance, Epidemiology, and End Results (SEER) database to verify the findings of a recent National Cancer Database (NCDB) study that identified factors predicting occult nodal involvement in cutaneous head and neck melanoma (CHNM) while identifying additional predictors of occult nodal metastasis and comparing two distinct cancer databases. METHODS: Cases of CHNM in the SEER database diagnosed between 2004 and 2014 were identified. Demographic information and oncologic data were obtained. Univariate and multivariate analysis were performed to identify factors associated with pathologic nodal positivity. RESULTS: There were 34002 patients with CHNM identified. Within this population, 16232 were clinically node-negative, 1090 of which were found to be pathologically node-positive. On multivariate analysis, factors associated with an increased risk of occult nodal metastasis included increasing depth of invasion (stepwise increase in adjusted odds ratio [OR]), nodular histology (aOR: 1.47 [95% CI: 1.21-1.80]), ulceration (aOR: 1.74 [95% CI: 1.48-2.05]), and mitoses (aOR: 1.86 [95% CI: 1.36-2.54]). Factors associated with a decreased risk of occult nodal metastasis included female sex (aOR: 0.80 [0.67-0.94]) and desmoplastic histology (aOR: 0.37 [95% CI: 0.24-0.59]). Between the SEER database and the NCDB, factors associated with occult nodal involvement were similar except for nodular histology and female sex, which did not demonstrate significance in the NCDB. CONCLUSION: Regarding clinically node-negative CHNM, the SEER database and the NCDB have similarities in demographic information but differences in baseline population sizes and tumor characteristics that should be considered when comparing findings between the two databases.

The outcomes of hypoglossal nerve stimulation in the management of OSA: A systematic review and meta-analysis.

OBJECTIVES: Obstructive sleep apnea (OSA) is a prevalent disease with significant health impacts. While first line therapy is CPAP, long-term compliance is low and device misuse is common, highlighting the need for alternative therapies. Upper airway surgery is one alternative, but substantial side effects hamper efficacy. A new alternative is an implantable hypoglossal nerve stimulator (HNS). These devices utilize neuromodulation to dilate/reinforce the airway and reduce side effects associated with traditional surgery. Several recent trials investigated the efficacy of these devices. The purpose of this study was to perform meta-analysis of available HNS studies investigating treatment of OSA to analyze objective and subjective outcomes and side effects. METHODS: A comprehensive literature search of PubMed and Scopus was performed. Two independent reviewers examined clinical trials investigating HNS in treatment of sleep apnea in adults. Studies with objective and subjective endpoints in sleep were included for analysis. Adverse events from trials were also recorded. RESULTS: Across 16 studies, 381 patients were analyzed. At 6 months (p = 0.008), mean SAQLI improved by 3.1 (95%CI, 2.6-3.7). At 12 months (p < 0.0001), mean AHI was reduced by 21.1 (95%CI, 16.9-25.3), mean ODI was reduced by 15.0 (95%CI, 12.7-17.4), mean ESS was reduced by 5.0 (95%CI, 4.2-5.8), mean FOSQ improved by 3.1 (95%CI, 2.6-3.4). Pain (6.2%:0.7-16.6), tongue abrasion (11.0%:1.2-28.7), and internal (3.0%:0.3-8.4)/external device (5.8%:0.3-17.4) malfunction were common adverse events. CONCLUSIONS: HNS is a safe and effective treatment for CPAP refractory OSA. Further study comparing HNS to other therapies is required.

Prognostic factors associated with achieving total oral diet after glossectomy with microvascular free tissue transfer reconstruction.

OBJECTIVE: Primary surgery followed by adjuvant therapy is the current standard of care in the multidisciplinary management of squamous cell carcinoma (SCC) of the oral tongue. Additionally, salvage glossectomy is used to treat recurrent base of tongue SCC. Microvascular free tissue transfer reconstruction (MVFTT) is utilized to maximize functional outcomes such as swallowing. We sought to identify prognostic factors related to achievement of a total oral diet in patients that underwent glossectomy with MVFTT. METHODS: Retrospective review at a tertiary care center from 2010 to 2015. RESULTS: 200 patients (69% male, mean age 60 years) met inclusion criteria. Extent of glossectomy was categorized as partial or hemiglossectomy (39%), tongue base resection with or without hemi-oral glossectomy (23%), composite resection with mandibulectomy (18%), and subtotal or total glossectomy (21%). Flap success rate was 96%. Median follow-up time was 14  months. A total oral diet was achieved by 49% of patients with median time to achievement of 31  days (IQR 9-209). Multivariate analysis identified body mass index  < 25 kg/m2, prior radiation therapy, adjuvant chemoradiation, and resection requiring subtotal or total glossectomy or concurrent mandibulectomy as independent risk factors for worse total oral diet achievement. CONCLUSION: Swallowing dysfunction represents a significant morbidity following glossectomy in the treatment of SCC. High BMI, smaller resection fields, and absence of prior radiation therapy or adjuvant chemoradiotherapy correlated with improved likelihood of obtaining a total oral diet. Patients should be appropriately counseled of this risk with emphasis placed on aggressive swallow rehabilitation in the post- treatment setting.

Inpatient Pediatric Epistaxis: Management and Resource Utilization.

OBJECTIVES: Epistaxis is a common condition that rarely warrants hospital admission in the pediatric population, making its inpatient management difficult to study. This study aims to use a nationwide database to analyze trends in the treatment of pediatric patients admitted with epistaxis and determine factors impacting total charges. METHODS: The latest (2012) version of the Kids' Inpatient Database (KID), Healthcare Cost and Utilization Project (HCUP), Agency for Healthcare Research and Quality was used to identify weighted discharges with the primary diagnosis of epistaxis. Information regarding demographics, comorbidities, treatment, hospital burden, and other admission details were obtained. Linear regression was used to analyze factors suspected to increase cost. RESULTS: Among 372 weighted discharges, the mean age was 9.68 years (SD = 5.79), and 60.0% were male. The most common comorbidities were thrombocytopenia, von Willebrand disease, and chronic sinusitis. The majority of admissions with epistaxis (56.7%) did not undergo any procedure to control epistaxis. Mean total charges was $30 208 (SD = $62 683) with a mean length of stay of 2.46 days (SD = 3.31). Independent predictors of increased charges included longer length of stay, admission from the emergency department, and median household income within the third quartile for patients' ZIP codes. Midwest hospital region independently predicted decreased charges. Having a procedure to control epistaxis did not significantly impact cost. CONCLUSIONS: Pediatric epistaxis admissions often do not require long hospital stays or procedural control of the bleed. However, significant charges are incurred treating epistaxis. Awareness of factors impacting these charges can potentially improve resource utilization.

Psoriasiform Hailey-Hailey Disease Presenting as Erythematous Psoriasiform Plaques Throughout the Body: A Case Report.

INTRODUCTION: Hailey-Hailey disease is an adult-onset skin condition characterized by lesions in the intertriginous regions of the body. The lesions can be pruritic, painful, and associated with physical and social impairment. CASE PRESENTATION: We present a case of psoriasiform Hailey-Hailey disease in a 60-year-old white woman who exhibited erythematous psoriasiform plaques in many areas of her body. The patient's condition was successfully treated with a twice-daily regimen of doxycycline, mometasone, and clindamycin. DISCUSSION: It is important to recognize this variant of Hailey-Hailey disease so it can be diagnosed and treated promptly. Hailey-Hailey disease can be treated with topical corticosteroids and antibiotics and usually is associated with a positive prognosis.

The Sinus and Nasal Quality of Life Survey (SN-5) in the Management of Pediatric Chronic Rhinosinusitis: A systematic review and meta-analysis.

OBJECTIVES: Pediatric chronic rhinosinusitis (CRS) is a prevalent condition with quality of life (QoL) impacts that are seldom reported in the literature. We aimed to conduct a systematic review and meta-analysis on studies using the Sinus and Nasal Quality of Life Survey (SN-5), the only validated symptom questionnaire in pediatric CRS. METHODS: A literature search was conducted to identify studies that used the SN-5 to measure QoL before and after medical or surgical interventions for pediatric CRS. Comparison of means and standard deviations was performed between pre- and post-intervention SN-5 scores. RESULTS: A total of 10 studies, consisting of 13 separate treatment arms of either medical therapy, adenoidectomy, balloon catheter sinuplasty (BCS), or functional endoscopic sinus surgery (FESS) were identified. The vast majority (92.3%) of the treatment arms demonstrated minimal clinically important differences between baseline and post-intervention SN-5 scores. Rates of treatment success and minimal clinically important difference among all treatment arms ranged from 43.2% to 94.0%. Comparison of means showed an improvement in SN-5 score of 1.97 [95% CI, 1.18 to 2.76; p < 0.00001] for BCS, 1.83 [95% CI, 1.47 to 2.19; p < 0.00001] for FESS, and 1.15 [95% CI, 0.36 to 2.66; p = 0.13) for medical treatment. CONCLUSION: There is a paucity of literature on QoL outcomes in pediatric CRS. More studies using the SN-5, particularly those controlling for baseline patient characteristics, are necessary to fully elucidate the impact of various interventions on QoL in pediatric CRS.

Granular cell differentiation: A review of the published work.

Since the initial description of the granular cell tumor in 1926, numerous other neoplasms, both benign and malignant, have been described to exhibit granular cell change. In most cases, diagnosis remains straightforward via recognition of retained histopathological morphology of the archetypal tumor, despite the presence of focal granular appearance. However, tumors with granular cell differentiation can present a diagnostic challenge either by mimicking alternative diagnoses, or by failing to exhibit architectural clues of the primary entity, thus requiring an immunohistochemical work-up. In light of this, it is important to be aware of the various entities that have been reported to exhibit granular cell morphology. In this review such tumors are discussed along with pertinent clinical and histopathological features.

Dietary Sodium Suppresses Digestive Efficiency via the Renin-Angiotensin System.

Dietary fats and sodium are both palatable and are hypothesized to synergistically contribute to ingestive behavior and thereby obesity. Contrary to this hypothesis, C57BL/6J mice fed a 45% high fat diet exhibited weight gain that was inhibited by increased dietary sodium content. This suppressive effect of dietary sodium upon weight gain was mediated specifically through a reduction in digestive efficiency, with no effects on food intake behavior, physical activity, or resting metabolism. Replacement of circulating angiotensin II levels reversed the effects of high dietary sodium to suppress digestive efficiency. While the AT1 receptor antagonist losartan had no effect in mice fed low sodium, the AT2 receptor antagonist PD-123,319 suppressed digestive efficiency. Correspondingly, genetic deletion of the AT2 receptor in FVB/NCrl mice resulted in suppressed digestive efficiency even on a standard chow diet. Together these data underscore the importance of digestive efficiency in the pathogenesis of obesity, and implicate dietary sodium, the renin-angiotensin system, and the AT2 receptor in the control of digestive efficiency regardless of mouse strain or macronutrient composition of the diet. These findings highlight the need for greater understanding of nutrient absorption control physiology, and prompt more uniform assessment of digestive efficiency in animal studies of energy balance.
