Emerging Vector-Borne Diseases.

Several mosquito-borne viral infections have recently emerged in North America; West Nile virus is the most common in the United States. Although West Nile virus generally causes a self-limited, flulike febrile illness, a serious neuroinvasive form may occur. Dengue is the most common vector-borne viral disease worldwide, and it has been a significant public health threat in the United States since 2009. Known as breakbone fever for its severe myalgias and arthralgias, dengue may cause a hemorrhagic syndrome. Chikungunya also causes flulike febrile illness and disabling arthralgias. Although meningoencephalitis may occur with chikungunya, bleeding is uncommon. Symptoms of Zika virus infection are similar to those of dengue, but milder. Zika virus increases the risk of fetal brain abnormalities, including microcephaly, if a pregnant woman is infected. Zika virus is spread through Aedes albopictus mosquito bites, is transmitted sexually, and may rarely spread nonsexually from person to person. Diagnosis of these vectorborne infections is clinical and serologic, and treatment is supportive. Other, well-established vector-borne diseases are also important. Ehrlichiosis is a tick-borne bacterial disease that presents as a nonspecific syndrome of fever, headache, malaise, and myalgias. It is diagnosed via blood smear testing, with confirmatory serology. Ehrlichiosis is treated with doxycycline. Rickettsial infections are transmitted by fleas, mites, and ticks, and severity ranges from mild to life threatening. Rocky Mountain spotted fever, the most significant rickettsial infection, is primarily a clinical diagnosis that presents as fever, headache, myalgias, petechial rash, and tick exposure. Doxycycline is effective for rickettsial infections if administered promptly. Vector avoidance strategies are critical to the prevention of all of these infections.

Inter-hospital transfers from rural hospitals to an academic medical center.

INTRODUCTION: The need for inter-hospital patient transfers from rural hospitals, especially Critical Access Hospitals, to larger, more urban hospitals is predictable considering the limited resources at rural hospitals. No systematic study of the inter-hospital transfers themselves has been published. The aim of this retrospective descriptive chart review was to provide a preliminary look at inter-hospital transfers from rural hospitals to a more urban, academic medical center in West Virginia. Ultimately, the creation of an agenda for further research was in view. METHODS: A list of study participants was generated from the academic center's electronic health record database. Study participants were patients who had been transferred for acute care, from November 2011 through June 2012, to the receiving hospital from another acute care hospital and had been under the care of the family medicine teaching service. RESULTS: One hundred and thirty-eight patient transfers were included. Medicare was the most common source of health insurance coverage but over a third of the patients were uninsured. Only five of the twenty-four referring hospitals were Critical Access Hospitals. Four institutions alone initiated 49.3% of transfers. Nineteen specialty services were sought with critical care and neurology accounting for 53.9% of requests. Stroke or stroke-like presentation was the most common transfer diagnosis. 24.6% of transfers were transferred for services that were available at the transferring facility. CONCLUSIONS: This study has suggested an agenda for further research that includes replication and analysis of the data with larger study samples as well as qualitative research into the transferring physicians' decision-making process.

Clinical efficacy of fixed-dose radioactive iodine for the treatment of hyperthyroidism at a single centre: our experience.

BACKGROUND: Iodine-131 is an effective treatment for thyrotoxicosis. In 2019, National Institute for Clinical Excellence guidelines (UK) suggested offering radioactive iodine as first-line definitive treatment for adults with Graves' disease, toxic nodular and multinodular goitre unless it is unsuitable or anti-thyroid drugs are likely to achieve remission. The aim of this study was to evaluate the clinical outcome 1 year after using fixed-dose Iodine-131 for hyperthyroidism and time (months) to response. METHODS: Electronic patient records were studied retrospectively for all patients who were treated with radioiodine therapy for hyperthyroidism between July 2017 and March 2020 at a district general hospital in the UK. Response to radioiodine therapy was initially assessed at 6 weeks and then at 3, 6, and 12 months by a dedicated thyroid nurse-led virtual follow-up. RESULTS: We identified 67 patients with a mean age of 55.9 years (range 18-84); 48 (72%) females, 19 (28%) males. Of these, 57 (85%) patients were cured at 12 months (93.7% in non-Graves', 82.3% in Graves' group). Gender, diagnosis and pre-treatment disease interval were not significantly associated with treatment success. Non-Graves' patients had a significantly shorter time to discharge than Graves' patients receiving Iodine-131 (8 versus 10.3 months, p = 0.0174). CONCLUSION: The results of the present study demonstrate that a single fixed dose of Iodine-131 therapy is highly effective and comparable to outcomes from calculated dose therapy in literature. We propose the routine use of scoring system to calculate risk of relapse for all newly diagnosed hyperthyroid patients to tailor treatment modality.

Malignancy rates and initial management of Thy3 thyroid nodules in a district general hospital: The 'Reading' experience.

BACKGROUND: Ultrasound-guided fine-needle aspiration cytology is the gold standard for investigating thyroid nodules. Stratifying the Thy3 thyroid nodule risk of malignancy is essential for clinical decision-making. According to the Royal College of Pathologists Guidance (2016), the rate of malignancy for Thy3a is 5-15% and for Thy3f 15-30%. Our aim was to investigate the malignancy rate and the initial management of Thy3 nodules in our institution. METHODS: A retrospective review was undertaken of 115 patients with Thy3 cytology results from thyroid fine-needle aspirations performed between January 2015 and June 2020 at a single centre. A total of 90 out of 115 patients underwent surgery. RESULTS: Of the 90 patients, we had a 40% malignant rate (36/90). Specifically, 14 of 34 (41.1%) Thy3a and 22 of 56 (39.2%) Thy3f nodules were malignant. Of the malignant lesions, 52.7% (19/36) were follicular thyroid carcinoma. 58.8% (10/17) of male patients and 35.6% (26/73) of female patients had a malignant histology. Eighteen patients eventually needed a completion thyroidectomy. CONCLUSION: Compared with national data, we showed a higher risk of malignancy in Thy3 nodules in our centre. Our study should encourage other centres to audit their own data. We propose setting up a national Thy3 registry as a basis to promote research in improving preoperative diagnosis of indeterminate thyroid nodules.

Family Physicians' Perspectives on Their Weight Loss Nutrition Counseling in a High Obesity Prevalence Area.

BACKGROUND: Obesity is a serious and highly prevalent health problem. Behavioral modification for weight loss is effective, and physician nutrition counseling is encouraged. Nevertheless, several studies have reported that physicians provide nutrition counseling infrequently. Time constraints and lack of patient compliance are among frequently reported barriers. AIM: In this pilot study, we aimed to examine physician weight loss nutrition counseling among family physicians in Huntington, West Virginia, an area with the highest obesity prevalence in the United States. METHODS: We administered an anonymous 13-question online survey designed for this study to all area family physicians in continuity ambulatory practice, asking about how often they provided nutrition counseling to their comorbidly obese patients, their nutrition education background, the counseling resources used, and the barriers they faced. RESULTS: Thirty-eight of the 47 invited physicians completed surveys. The 35 to 55 age group comprised 55% of the respondents. Men comprised 53% of our sample. Two-thirds of the physicians reported that they counseled at a high frequency. Twenty-six of the 38 physicians reported that their nutrition education in medical school was none to minimal. Of the rest, 47.2% viewed their education as clinically relevant. The most frequently-used specific patient education sources were those embedded in electronic health records, the US Department of Agriculture's MyPlate tool, and a variety of smartphone-based apps. Time constraints and lack of patient interest in nutrition topics were the leading barriers cited. CONCLUSION: Family physicians practicing in the most obese population in the United States tend to be high-frequency obesity nutrition counselors who frequently use specific tools, consider their education lacking and face oft-cited barriers. Studies in other highly endemic areas are needed to confirm these findings.

Hoarse voice: a rare presentation of tuberculosis lymphadenitis.

A man aged 37 years from Indian descent presented to an inner city London hospital with hoarseness of voice, fatigue, night sweats and a 2 kg weight loss. Laryngoscopy demonstrated a left vocal fold palsy. Extensive investigations were undertaken with disseminated malignancy being primarily investigated. CT/MRI scanning showed non-specific necrotic mediastinal lymph nodes. Tuberculin skin testing, cytology and PCR were eventually undergone. Tests yielded results consistent with tuberculosis (TB) infection and the patient was started on standard TB treatment protocol, with excellent results. TB infection can result in multiple atypical presentations of disease, including hoarseness of voice secondary to vocal cord paralysis. This is a rare but important presentation for community clinician's to consider, especially in populations where TB is epidemiologically thought to be prevalent.
