Comparing Travel Distance to Care and Staging of Parotid Gland Malignancies in South Dakota and Surrounding States.

BACKGROUND: Parotid gland malignancies are difficult to characterize in terms of incidence and risk factors due to their relatively rare occurrence. Common cancers often present more aggressively in rural areas, albeit occurring less frequently. Some previous studies have found increased distance to care has been linked to more advanced malignancies. This study hypothesized decreased access to parotid gland malignancy specialists (otolaryngologists or dermatologists), evaluated as longer travel distances, would be associated with more advanced staging of parotid gland malignancies. METHODS: A retrospective chart review of the Sanford Health system electronic medical record in South Dakota and surrounding states from 2008-2018 was conducted to obtain data of parotid gland malignancies, respective staging, and patient home addresses to assess distance, both driving and straight-line, to the nearest parotid gland malignancy specialist, including outreach clinics. Travel distance was categorized (0-20 miles, 20-40 miles, and 40+ miles) and compared to categorized tumor stage (early 0/I, late II/III/IV) using a Fisher's Exact test. RESULTS: Overall, chart review yielded 134 patients with parotid gland malignancies from 2008-2018 in the Sanford Health system and associated data was gathered. The malignancies were categorically organized as 52.3 percent in early stage (0/I) vs. 47.7 percent in late (II/III/IV). When comparing parotid malignancy stage to driving distance, no significant association was found when outreach clinics were excluded (p=0.938) or included (p=0.327). When comparing parotid malignancy stage to straight-line distance, no significant association was found when outreach clinics were excluded (p=0.801) or included (p=0.874). CONCLUSIONS: Although no association was established between travel distance and parotid gland malignancy staging, further studies are needed to evaluate at population levels the incidence of parotid gland malignancies in rural communities and if there are specific risk factors in these areas for these malignancies which is currently unknown.

Aggressive Langerhans cell histiocytosis following T-cell acute lymphoblastic leukemia.

A 4-year-old female child developed cutaneous Langerhans cell histiocytosis 6 months following a diagnosis of T-cell acute lymphoblastic leukemia. Imaging revealed no evidence of systemic disease. Seven months later, the first systemic lesion was discovered on laryngoscopy. Restaging Positron Emission Tomography - Computed Tomography at that time revealed new 18-fluorodeoxyglucose-positive lesions in the left apical pleural margin, right lower peri-esophageal region, left ventricular myocardium, pancreas, upper pole of the left kidney, and inguinal and gluteal regions consistent with progressive systemic disease. Genomic testing revealed a low tumor mutational burden as well as mutations in KRAS G12A, ARID1A Q524, CDKN2A/B loss, and an alteration in NOTCH1.

A Case of Birt-Hogg-Dube Syndrome.

Birt-Hogg-Dube (BHD) syndrome is a rare condition that typically presents with a triad of benign cutaneous papules including fibrofolliculomas, pulmonary cysts and pneumothoraxes, and renal tumors. Though a rare disease, it is an important diagnosis so that monitoring for a renal neoplasm can begin. In this case report we discuss an asymptomatic patient diagnosed with BHD after undergoing a routine skin exam and highlight the importance of diagnosis so that routine screening can be implemented.

Insidious Blastomycoses Osteomyelitis in a Young, Immunocompetent Male.

Blastomyces is a fungus that is endemic to the Ohio and Mississippi River Valleys and Great Lakes region. The fungus is a rare cause of infection, but most commonly causes infections of the lungs followed by the skin and bones. Infection of the bone is often not clinically suspected, which can slow the diagnosis. In this report, we present a case of Blastomyces osteomyelitis in a young, immunocompetent male.

Student Initiative Improves HIV Screening Rate in Student-Run Free Clinic.

Background The Center for Disease Control provides recommendations for preventative services and screenings including recommendations for a one-time HIV screening of all adult patients between the ages of 13-64. But not all clinics are fully compliant with these recommendations. We identified a need for increased screening at two clinics in a rural setting. As a healthcare quality improvement initiative, we developed educational informatics to increase screening compliance. Methods This project assessed HIV screening rates before and after educational interventions at two clinics, the Coyote Clinic and the Avera Downtown Clinic. Three changes were implemented to increase the HIV screening rate and ultimately provide more effective high-quality health care. The three initiatives focused on patients, physicians, and student volunteers in order to provide a strong foundation of knowledge to all parties involved in a patient's care. Results Prior to any interventions, the baseline screening rate (screenings/100 persons) at the Avera Downtown Clinic was 0.84 while the screening rate at the Coyote Clinic was 0.00. After the proposed interventions, the screening rate of the Downtown Clinic improved to 3.97 and the screening rate at the Coyote Clinic improved to 29.4. Using a Fisher's Exact test, we found a statistically significant post-intervention increase in HIV screening at the Coyote Clinic after the intervention (p = 0.0002) but not at the Downtown Clinic (p = 0.0940.) Conclusion HIV screening rates improved after the implementation of interventional education initiatives tailored for patients, medical students, and physicians. Implementation of low-cost quality improvement measures such as the ones detailed herein may significantly improve long-term patient management, particularly in the context of screening tests.
