Management and referral patterns for new-onset chronic cough in primary care patients.

Background: The diagnosis and management of chronic cough in primary care is challenging despite it being one of the most common chronic conditions. Objective: Clinical characterization of patients with new-onset chronic cough in the primary care setting. Methods: This was a retrospective study of adult patients (ages ≥ 18 years) with at least three visits with primary care providers (PCP) for new-onset cough, with at least 8 weeks between the first and third visits, within a tertiary-care center and affiliated clinics between January 1, 2010, and January 1, 2019 (N = 174). We calculated the frequency of primary care visits, diagnostic testing, specialist referrals, and prescribed medications up to 18 months after the third visit with a PCP for cough. Results: Of 174 patients who met the criteria of new-onset chronic cough, >50% had four or more primary care visits related to cough. Despite that, 91 (52.3%) did not receive a referral to a specialist, and 41 (23.5%) did not receive an order for a chest radiograph during the evaluation of the chronic cough. Antibiotics and systemic corticosteroids were prescribed to 106 (61%) and 63 (36%) of the patients, respectively, and 20% were prescribed opiates. No patients were prescribed central-neuromodulating agents, and angiotensin-converting enzyme inhibitors were discontinued in 48% of the patients who were taking them (12/25). Conclusion: We found considerable heterogeneity and discrepancies with clinical guideline recommendations in patients who presented with new chronic cough. There is a substantial unmet need to study chronic cough in the primary care setting to inform important stakeholders.

National assessment of lymph node status indicators & predictors in pediatric head and neck rhabdomyosarcomas in the US.

OBJECTIVES: Assessing the prognostic utility of lymph node status in pediatric rhabdomyosarcoma (RMS) patients and identifying demographic and clinical predictors of positive lymph node status among pediatric rhabdomyosarcoma patients. STUDY DESIGN: Retrospective cohort study of head and neck RMS in patients with and without positive lymph node metastasis. METHODS: National Cancer Database (NCDB) was queried for patients of young (0-11 years) and adolescent (12-21 years) ages with head and neck RMS and confirmed positive or negative lymph node metastasis status. Descriptive analyses, Kaplan-Meier survival analyses, and multivariate logistic regressions were performed on extracted demographic and clinical characteristics. RESULTS: Among 272 head and neck RMS patients, 146 (54%) were found to have positive lymph node metastasis. Alveolar RMS (n = 147, 54%) followed by embryonal RMS (n = 74, 27%) were the most represented histology types. Positive lymph node metastasis conferred significantly decreased survivability (p < 0.001) with a median survival period of 36.42 months compared to negative lymph node metastasis with a period of 53.47 months. Older age showed markedly increased odds (OR-2.02; 95%CI 1.22-3.38) of having lymph node metastasis when controlling for sex, race, insurance status, and Charlson-Comorbidity score. Alveolar histologies showed markedly increased odds of having lymph node metastasis (OR-3.21; 95%CI 1.96-5.31); embryonal histologies showed markedly decreased odds of having lymph node metastasis (OR-0.32; 95%CI 0.18-0.56) CONCLUSIONS: This study highlights the significant prognostic value of lymph node status among pediatric head and neck rhabdomyosarcoma patients while showcasing crucial demographic and pathological predictors of lymph node metastasis in said patients. Use of lymph node status in pediatric head and neck rhabdomyosarcoma will present future steps towards improving its clinical course.

Exploring the Epidemiology and Survival Trends in Pediatric Major Salivary Gland Malignancies: Insights from the National Cancer Database.

OBJECTIVE: To investigate the clinicopathological, therapeutic, and survival data on pediatric major salivary gland cancers. MATERIALS AND METHODS: National Cancer Database (NCDB) query from 2004 to 2018. RESULTS: In total, 967 cases of individuals under the age of 21 were identified. Most cancers affected the parotid gland (86%). Mucoepidermoid carcinoma (41.3%) and acinic cell adenocarcinoma (33.6%) were the most common. Tumors occurred more often from age 11 to 21, and females were more affected. Histology varied by age, gender, and race. In the 0-5 age group, mucoepidermoid carcinoma and myoepithelial carcinoma/sarcoma/rhabdomyosarcoma were the most common pathologies. In patients over 5 years old, mucoepidermoid carcinoma was the most frequent tumor in boys, while acinic cell adenocarcinoma was more common in girls. African American patients had a higher incidence of mucoepidermoid carcinoma, while White patients in the 0-5 age group had a higher incidence of myoepithelial carcinoma/sarcoma/rhabdomyosarcoma tumors. Low-grade tumors were commonly diagnosed at stage I, but the 0-5 age group had a high frequency of stage IV tumors. The overall 5-year survival rate was 94.9%, with 90% for the 0-5 years age group and 96% for the 11-15 years age group. Negative margins were associated with higher 5-year survival rates in high-stage tumors (93%) compared to positive margins (80%). Submandibular malignancies had worse 5-year survival rates across all age groups. CONCLUSIONS: Major salivary gland malignancies in pediatric patients exhibit variations in histopathologic characteristics by age, gender, and race. Negative margins impact 5-year survival rates, especially in high-stage tumors.
