Pediatric Cannabis Single-Substance Exposures Reported to the Michigan Poison Center From 2008-2019 After Medical Marijuana Legalization.

BACKGROUND: Legalization of medical and recreational cannabis is a major contributor to pediatric cannabis exposures. The trends and magnitude of pediatric cannabis exposures in Michigan after medical cannabis legalization in 2008 have not been assessed. OBJECTIVE: To describe the temporal trends of pediatric cannabis exposures reported to the Michigan Poison Center (MiPC) after medical cannabis was legalized in 2008 and 1 year after legalization of recreational cannabis in 2018. METHODS: Retrospective electronic chart review of pediatric (<18 years old) single-substance cannabis exposures reported to the MiPC from January 1, 2008 to December 31, 2019. Routes of cannabis exposure were reported as ingestion, inhalation, and unknown. Types of ingested cannabis products were also documented. RESULTS: Between 2008 and 2019, 426 pediatric cannabis single exposures were reported. The median patient age was 6.0 years (interquartile range 2-15 years). Age distribution was bimodal. A total of 327 (76.8%) exposures were from cannabis ingestion, 79 (18.5%) from inhalation, 2 (0.5%) from both ingestion and inhalation, and 18 (4.2%) from unknown route. The doubling time for number of cases was 2.1 years, and the total number of annual reported cases increased after 2016. Teenagers (13-17 years) had the highest number of inhalational exposures, whereas young children (0-5 years) had the highest number of ingestions. CONCLUSION: Single-substance pediatric cannabis exposures reported to the Michigan Poison Center increased after medical cannabis was legalized in 2008 through recreational legalization in 2018.

LINGUAL THYROID: 35-YEAR EXPERIENCE AT A TERTIARY CARE REFERRAL CENTER.

OBJECTIVE: Lingual thyroid (LT) results from a developmental abnormality due to failure of the thyroid gland to descend to its pretracheal position. Given the low incidence of this disease, standardized management recommendations are lacking. We aimed to describe our institution's experience in LT management and to suggest a practice algorithm. METHODS: We conducted a retrospective review of LT diagnosed at Mayo Clinic, Rochester, Minnesota, between 1976 and 2010. Demographics, clinical presentation, laboratory data, treatment received, and outcomes were collected. RESULTS: We identified 29 patients with LT. Eighty-three percent were female; age at diagnosis ranged from 2 weeks to 68 years. Almost one-third of patients were symptomatic, with the most common symptoms being cough and hoarseness. The diagnosis of LT was incidental in 9 patients (31%). Seventy-two percent of patients developed hypothyroidism. Levothyroxine was the treatment of choice, followed by thyroidectomy. Two asymptomatic euthyroid patients were followed without any intervention. CONCLUSION: Management of patients with LT should be individualized and guided by the patient's symptoms and thyroid hormone status.

Outgoing initial healthcare facility follow-up call metrics and barriers within a single United States poison center.

INTRODUCTION: Specialists in poison information are responsible for following-up with exposure cases managed at healthcare facilities. However, the amount of time, call components, and barriers met when completing an initial healthcare facility follow-up call in which a large amount of data and clinical recommendations are shared is not well described. METHODS: A retrospective observational study was conducted by randomizing healthcare facility initial follow-up calls from January to April 2022. One hundred and thirty calls that met the inclusion criteria were randomly selected. We recorded seven unique time intervals within each call. Day of the week, time of day, and variability amongst specialists in poison information were also assessed. RESULTS: Initial follow-up calls took a median of 7.2 min. Most (67%) follow-up calls were directed to emergency departments. Barriers to completion of calls were most commonly due to the healthcare reporter being busy (37%) and specialists in poison information being placed on terminal hold (30%). There was variability between specialists in poison information in the time for healthcare reporter to share data (P < 0.0001), time for specialists in poison information recommendations (P = 0.0076), and total time (P = 0.0003). DISCUSSION: Variability exists amongst specialists in poison information during periods of information exchange, particularly when the healthcare reporter is providing information and subsequently when the specialist in poison information is providing recommendations. Barriers to completing calls centered around healthcare reporter being busy or the specialist in poison information being placed on a terminal hold. There was no correlation with the time or day of the week. CONCLUSIONS: With notable variability in these calls during periods of intense communication of data and treatment recommendations, there are likely opportunities for specialists in poison information and poison center directors to work together to address variability and overcome barriers to completing initial hospital follow-up calls. Further studies to evaluate variability amongst specialists in poison information are the next steps in understanding this complex topic.

Clinician feedback using a shared decision-making tool for the evaluation of patients with thyroid nodules-an observational study.

BACKGROUND: We pilot-tested an encounter conversation aid to support shared decision making (SDM) between patients with thyroid nodules and their clinicians. OBJECTIVE: Characterize the clinician feedback after providing care to patients with thyroid nodules using a tool to promote SDM conversations during the clinical encounter, and evaluate how clinicians used the tool during the visit. METHODS: Mixed method study in two academic centers in the U.S., including adult patients presenting for evaluation of thyroid nodules and their clinicians. We thematically analyzed interviews with clinicians after they used the SDM tool in at least three visits to characterize their feedback. Additionally, investigators evaluated visits recordings to determine the extent to which clinicians engaged patients in the decision-making process (OPTION score, scale 0 to 100, higher levels indicating higher involvement), the tool's components used (fidelity), and encounter duration. Using a post-visit survey, we evaluated the extent to which clinicians felt the tool was easy to use, helpful, and supportive of the patient-clinician collaboration. RESULTS: Thirteen clinicians participated in the study and used the SDM tool in the care of 53 patients. Clinicians thought the tool was well-organized and beneficial to patients and clinicians. Clinicians noticed a change in their routine with the use of the conversation aid and suggested it needed to be more flexible to better support varying conversations. The median OPTION score was 34, the fidelity of use 75%, and the median visit duration 17 min. In most encounters, clinicians agreed or strongly agreed the tool was easy to use (86%), helpful (65%), and supported collaboration (62%). CONCLUSION: Clinicians were able to use a SDM tool in the care of patients with thyroid nodules. Although they wished it were more flexible, they found on the whole that its use in the clinical encounter was beneficial to patients and clinicians.

Patient feedback receiving care using a shared decision making tool for thyroid nodule evaluation-an observational study.

PURPOSE: To characterize the feedback of patients with thyroid nodules receiving care using a shared decision making (SDM) tool designed to improve conversations with their clinicians related to diagnostic options (e.g. thyroid biopsy, ultrasound surveillance). METHODS: Investigators qualitatively analyzed post-encounter interviews with patients to characterize their feedback of a SDM tool used during their clinical visits. Additionally, investigators counted instances of diagnostic choice awareness and of patients' expression of a diagnostic management preference in recordings of clinical encounters of adult patients presenting for evaluation of thyroid nodules in which the SDM tool was used. RESULTS: In total, 53 patients (42 (79%) women); median age 62 years were enrolled and had consultations supported by the SDM tool. Patients were favorable about the design of the SDM tool and its ability to convey information about options and support patient-clinician interactions. Patients identified opportunities to improve the tool through adding more content and improve its use in practice through training of clinicians in its use. There was evidence of diagnostic choice awareness in 52 (98%) of these visits and patients expressed a diagnostic management preference in 40 (76%). CONCLUSION: User centered design including feedback from patients and real life observation supports the use of the SDM tool to facilitate collaboration between patients and clinicians.

Truncal Ataxia and Prolonged Coma in an Exploratory Pediatric Perampanel Ingestion.

INTRODUCTION: Several overdoses of the antiepileptic drug perampanel have been reported in adults, but very few have been reported in children. We report the case of an observed exploratory ingestion of perampanel in a 2-year-old child that resulted in ataxia and prolonged coma. CASE REPORT: A previously healthy 2-year-old female patient presented to the emergency department (ED) 30 minutes after the witnessed ingestion of 30 mg of perampanel (2 mg/kg). Within minutes of ingestion, she displayed ataxia and inability to walk. Upon ED presentation, she had normal vital signs but was minimally responsive with physical stimulation. Naloxone was given without response. She was intubated because of profound central nervous system depression and transferred to a pediatric tertiary care facility. She remained intubated with no pharmacological sedation. Physical exam showed a horizontal nystagmus. Detailed neurologic examination of ataxia and coordination was not possible, and she did not demonstrate hyperreflexia, clonus, or rigidity. Her mental status gradually improved, and she was extubated approximately 72 hours after exposure. After extubation, the patient still exhibited truncal ataxia and did not return to baseline until 96 hours post ingestion. Serum drawn approximately 16 hours after exposure showed 870 ng/mL perampanel (ref < 20 ng/mL). She remained hemodynamically stable throughout her hospital course, despite protracted depressed mental status. DISCUSSION: Given the severity of our patient's presentation, pediatric patients showing symptoms of perampanel overdose should be triaged to the ED for evaluation in anticipation of a prolonged clinical course with decreased consciousness and hypoventilation.

Stimulant storm - state health department psychostimulant age-adjusted mortality rate correlates with psychostimulant-based Michigan Poison Center case exposures over time.

BACKGROUND: Deaths attributable to psychostimulants with abuse potential have increased in the United States (US) in recent years. Methamphetamine use, in particular, has risen sharply. We evaluated the correlation between amphetamine- and methamphetamine-related case exposures reported to the Michigan Poison Center (MiPC) coinciding with psychostimulant age-adjusted mortality rates from the Michigan Department of Health and Human Services (MDHHS). METHODS: We compared amphetamine and methamphetamine exposures reported to the MiPC from 2012 to 2018, queried from ToxSentry® database, to MDHHS reports on resident death certificates with attributed death due to "overdose, regardless of intent" and related cause of death attributed to psychostimulants with abuse potential. Linear regression assessed goodness-of-fit. Slope with standard error and adjusted R2 were reported. Psychostimulants included methamphetamine, 3,4-methylenedioxy-methamphetamine (MDMA), dextroamphetamine, levoamphetamine, and methylphenidate. RESULTS: Psychostimulant deaths reported by MDHHS increased from 17 to 165 between 2012 and 2018. The average age-adjusted rate of psychostimulant-involved overdose deaths per 100,000 state residents rose from 0.2 to 1.8. Linear regression of MiPC amphetamine exposure rates with state health department-reported age-adjusted psychostimulant mortality rates yielded a slope of 1.93, SE 0.5, p value 0.035, and adjusted R2 0.55. Linear regression of MiPC methamphetamine exposure rates with state health department-reported age-adjusted psychostimulant mortality rates yielded a slope of 0.78, SE 0.27, p value 0.012, and adjusted R2 0.70 suggesting a strong correlation. CONCLUSION: Psychostimulant use and associated deaths in the US are increasing, representing an evolving public health threat. Michigan demonstrates consistency with national trends and data from the MiPC correlates strongly with state-reported age-adjusted psychostimulant mortality rates. Strengthening collaboration between poison centers and state health departments is critical for detection and mitigation efforts and can thereby inform resource allocation.

A Pilot Trial of Topical Capsaicin Cream for Treatment of Cannabinoid Hyperemesis Syndrome.

OBJECTIVES: Patients with cannabinoid hyperemesis syndrome (CHS) present frequently to the emergency department. Previous case studies suggest dramatic symptomatic improvement with topical capsaicin treatment. This exploratory study examined the potential effectiveness of topical capsaicin in patients with nausea and vomiting due to a suspected CHS exacerbation. METHODS: This was a double-blind, randomized placebo-controlled pilot trial. Adults who presented with vomiting suspected to be from CHS were eligible for enrollment. We excluded pregnant women and those with resolution of symptoms. Following randomization, topical 0.1% capsaicin or placebo cream was applied to the anterior abdomen in a uniform manner. The primary outcome was the severity of nausea on a visual analog scale (VAS) of 0 to 10 cm assessed at 30 minutes. Secondary outcomes were adverse events, occurrence of posttreatment vomiting, nausea by VAS at 60 minutes, and hospital admission. RESULTS: This pilot trial enrolled 30 patients, 17 in the capsaicin arm and 13 in the placebo arm. One patient in the capsaicin arm did not tolerate treatment due to skin irritation. Mean ± SD nausea severity at 30 minutes was 4.1 ± 2.3 cm in the capsaicin arm and 6.1 ± 3.3 cm in the placebo arm (difference = -2.0 cm, 95% confidence interval [CI] = 0.2 to -4.2 cm). At 60 minutes, mean ± SD nausea severity was 3.2 ± 3.2 cm versus 6.4 ± 2.8 cm (difference = -3.2 cm, 95% CI = -0.9 to -5.4 cm). The percent reduction in nausea at 60 minutes from baseline was 46.0% in the capsaicin arm and 24.9% in the placebo arm (difference = 21.1%, 95% CI = -5.6% to 47.9%). A higher proportion of capsaicin group patients (29.4% vs. 0%) had complete resolution of nausea (relative risk = 3.4, 95% CI = 1.6 to 7.1). CONCLUSION: In this pilot trial, the application of topical capsaicin cream was associated with a significant reduction in nausea at 60 minutes but not at 30 minutes and provided more complete relief of nausea.

Development and application of magnetic resonance elastography of the normal and pathological thyroid gland in vivo.

PURPOSE: To noninvasively assess the shear stiffness of the thyroid gland in vivo in order to determine whether magnetic resonance elastography (MRE) might hold clinical utility in the diagnosis of thyroid disease. MATERIALS AND METHODS: Quantitative parametric images of thyroid stiffness in normal volunteers and patients were produced and quantitative stiffness values measured. Average gland stiffness was determined by region of interest analysis of the parametric images. This technique was used to assess stiffness of the thyroid in normal individuals (n = 12), patients with Hashimoto's thyroiditis (HT; n = 5), and patients with a solitary benign (n = 8) or malignant (n = 2) thyroid nodule. RESULTS: Mean shear modulus of normal thyroid glands was 1.9 +/- 0.6 kPa at 100 Hz and 1.3 +/- 0.5 kPa at 80 Hz, while that of HT glands was 2.8 +/- 0.6 kPa and 1.8 +/- 0.6 kPa at 80 Hz, respectively (P = 0.004 at 100 Hz). Elastographic parameters could not differentiate benign from malignant thyroid nodules in these small sample sizes. CONCLUSION: We developed a method for the application of MRE to the study of thyroid gland pathology. The results show that the HT gland can be differentiated from normal thyroid. The clinical utility of this imaging modality in the diagnosis and management of thyroid disease awaits further study.

Assessment of The Bethesda System for Reporting Thyroid Cytopathology.

OBJECTIVES: Long-term follow-up is important for determining performance characteristics of thyroid fine-needle aspiration (FNA). METHODS: Histologic or 3 or more years of clinical follow-up was used to calculate performance characteristics of thyroid FNA before and after implementation of The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) classification was also investigated. RESULTS: Follow-up was obtained for 1,277/1,134 and 1,616/1,393 aspirates/patients (median clinical follow-up, 9.9 and 4.4 years, pre- and post-TBSRTC, respectively). Nondiagnostic, suspicious for follicular neoplasm, and suspicious for malignancy (SFM) diagnoses decreased and benign diagnoses increased post-TBSRTC, while atypical rate remained less than 1%. Negative predictive value for benign nodules and positive predictive value (PPV) for SFM increased significantly. Eleven nodules were reclassified as NIFTP, slightly decreasing PPV/risk of malignancy (ROM). CONCLUSIONS: Appropriate ROM for thyroid FNA can be achieved through application of TBSRTC terminology with minimal use of atypical category.

To be or not TB.

A 20-year-old Somali woman presented with a tender, enlarging neck mass in the setting of weight loss and tachycardia. This was initially thought to be a thyroid storm. On further investigation, she had suppurative thyroiditis from Mycobacterium tuberculosis. This case illustrates a high prevalence of extrapulmonary tuberculosis (TB) in foreign-born individuals and the necessity to consider TB in the differential diagnosis of an enlarging neck mass.

Outcomes of Radiofrequency Ablation Therapy for Large Benign Thyroid Nodules: A Mayo Clinic Case Series.

OBJECTIVE: To assess the effectiveness, tolerability, and complications of radiofrequency ablation (RFA) in patients with benign large thyroid nodules (TNs). PATIENTS AND METHODS: This is a retrospective review of 14 patients with predominantly solid TNs treated with RFA at Mayo Clinic in Rochester, Minnesota, from December 1, 2013, through October 30, 2016. All the patients declined surgery or were poor surgical candidates. The TNs were benign on fine-needle aspiration, enlarging or causing compressive symptoms, and 3 cm or larger in largest diameter. We evaluated TN volume, compressive symptoms, cosmetic concerns, and thyroid function. RESULTS: Median TN volume reduction induced by RFA was 44.6% (interquartile range [IQR], 42.1%-59.3%), from 24.2 mL (IQR, 17.7-42.5 mL) to 14.4 mL (IQR, 7.1-19.2 mL) (P<.001). Median follow-up was 8.6 months (IQR, 3.9-13.9 months). Maximum results were achieved by 6 months. Radiofrequency ablation did not affect thyroid function. In 1 patient with subclinical hyperthyroidism due to toxic adenoma, thyroid function normalized 4 months after ablation of the toxic nodule. Compressive symptoms resolved in 8 of 12 patients (67%) and improved in the other 4 (33%). Cosmetic concerns improved in all 8 patients. The procedure had no sustained complications. CONCLUSION: In this population, RFA of benign large TNs performed similarly to the reports from Europe and Asia. It induces a substantial volume reduction of predominantly solid TNs, improves compressive symptoms and cosmetic concerns, and does not affect normal thyroid function. Radiofrequency ablation has an acceptable safety profile and should be considered as a low-risk alternative to conventional treatment of symptomatic benign TNs.

Patients' knowledge about the outcomes of thyroid biopsy: a patient survey.

PURPOSE: Fine-needle aspiration biopsy of the thyroid is an increasingly common outpatient procedure. Patients are counseled about the indications and risks of this procedure and informed consent is obtained. We aimed to assess the extent to which patients acquired necessary knowledge during this process. METHODS: Survey study conducted in a thyroid nodule clinic at a referral center. Adult patients who had just undergone a thyroid biopsy were asked to complete a survey, including eight questions regarding the indications and potential outcomes of thyroid biopsy. The main outcome of the study was to assess the patients' knowledge based on the response to each individual survey question. RESULTS: Two-hundred and ninety-seven patients were eligible, of which 196 (66%) completed the survey: most were women (76%), had adequate reading health literacy (95%) and a mean age of 58 years. Although 86% of patients correctly identified evaluation for thyroid cancer as the main indication for their biopsy, 56% were not aware of the likelihood of this diagnosis. Almost all (>90%) of respondents knew that results could be benign or malignant; fewer were aware of non-diagnostic (71%) or indeterminate (68%) outcomes, or of the need for additional diagnostic testing after the biopsy (33%). CONCLUSIONS: After undergoing thyroid biopsy, a high proportion of well-educated patients remained unaware of their risk for thyroid cancer, potential outcomes, and downstream consequences of their biopsy. This quality gap raises the possibility that informed consent procedures that meet legal standards may leave patients undergoing thyroid biopsy paradoxically uninformed.

Clinical, Biochemical, and Radiological Characteristics of a Single-Center Retrospective Cohort of 705 Large Adrenal Tumors.

OBJECTIVE: To characterize large adrenal tumors (≥4 cm in diameter) and to identify features associated with malignancy. PATIENTS AND METHODS: We investigated the clinical, biochemical, and imaging characteristics in a large retrospective single-center cohort of patients with adrenal tumors of 4 cm or more in diameter during the period of January 1, 2000, through December 31, 2014. RESULTS: Of 4085 patients with adrenal tumors, 705 (17%) had adrenal masses measuring 4 cm or more in diameter; of these, 373 (53%) were women, with a median age of 59 years (range, 18-91 years) and median tumor size of 5.2 cm (range, 4.0-24.4 cm). Underlying diagnoses were adrenocortical adenomas (n=216 [31%]), pheochromocytomas (n=158 [22%]), other benign adrenal tumors (n=116 [16%]), adrenocortical carcinomas (n=88 [13%]), and other malignant tumors (n=127 [18%]). Compared with benign tumors, malignant tumors were less frequently diagnosed incidentally (45.5% vs 86.7%), were larger (7 cm [range, 4-24.4 cm] vs 5 cm [range, 4-20 cm]), and had higher unenhanced computed tomographic (CT) attenuation (34.5 Hounsfield units [HU] [range, 14.1-75.5 HU] vs 11.5 HU [range, -110 to 71.3 HU]; P<.001). On multivariate analysis, older age at diagnosis, male sex, nonincidental mode of discovery, larger tumor size, and higher unenhanced CT attenuation were all found to be statistically significant predictors of malignancy. CONCLUSION: The prevalence of malignancy in patients with adrenal tumors of 4 cm or more in diameter was 31%. Older age, male sex, nonincidental mode of discovery, larger tumor size, and higher unenhanced CT attenuation were associated with an increased risk for malignancy. Clinical context should guide management in patients with adrenal tumors of 4 cm or more in diameter.

Amyloid goiter as a manifestation of primary systemic amyloidosis.

Primary amyloidosis involving the thyroid gland is rare and limited to case reports. We report the case of a previously healthy 47-year-old female presenting with a 1-month history of nausea, vomiting, and diffuse thyroid enlargement. Over the next 3 months, she simultaneously developed renal insufficiency dysphagia and hoarseness of voice. Biopsies from the gastric antrum, duodenum, bone marrow, and kidney were positive for vascular deposition of amyloid. Ultrasound of the thyroid revealed diffuse enlargement of the thyroid gland, which was 32.8 ML in volume, with diffuse hyperechogenicity. Fine needle aspiration (FNA) biopsy was positive for amyloid by Congo red staining, and cytology was negative for malignancy. The patient was treated with dexamethasone 40 mg daily on days 1-4, 9-12, and 17-20 for 3 months. On 3-month follow-up, the patient's nausea and vomiting had resolved and renal insufficiency improved. Ultrasound of the thyroid demonstrated decrease in the size of the goiter to 23.2 ML. Amyloid goiter is seen only in approximately 0.04% of patients with primary systemic amyloidosis. No data is currently available regarding treatment of primary amyloidosis and its effect on the goiter. However, we have evidence demonstrating that successful treatment of amyloidosis decreases thyroid enlargement and improves organ dysfunction.

Risk of Malignancy in Thyroid Nodules with Non-Diagnostic Fine-Needle Aspiration: A Retrospective Cohort Study.

BACKGROUND: Fine-needle aspiration (FNA) of thyroid nodules is commonly performed, and despite the use of ultrasound (US) guidance, the rate of non-diagnostic FNAs is still significant. The risk of malignancy of thyroid nodules with a non-diagnostic FNA is not clearly defined. However, most studies exclude the majority of patients without a repeat biopsy or surgery, thus increasing the likelihood of selection bias. The aims of this study were to determine the malignancy risk in nodules with an initial non-diagnostic FNA, and to identify the factors associated with malignancy. METHODS: This was a retrospective cohort study of patients with thyroid nodules who underwent US-guided FNA between 2004 and 2010 and had a non-diagnostic result. Patients were followed until confirmatory diagnosis of the nature of the nodule was made. The outcome of malignant or benign disease was based on one of the following: (i) final surgical pathology following thyroidectomy; (ii) repeat biopsy; (iii) clinically, based on repeat ultrasound performed at least three years following biopsy; or (iv) report of thyroid status for patients without follow-up visits contacted by mail. RESULTS: There were 699 nodules from 665 patients included. The mean age was 59 ± 15 years, and 71.7% were women. There was complete follow-up of 495 nodules. After a median follow-up of 2.7 years, thyroid cancer was found in 15 nodules. The prevalence of malignancy was 3% (15/495). The presence of nodular calcifications was the strongest predictor of thyroid malignancy (odds ratio 5.03 [confidence interval 1.8-14.7]). Initial nodule size was inversely associated with malignancy (odds ratio 0.55 [confidence interval 0.28-0.93]). However, the 193 patients without follow-up had smaller nodules compared with those included in the analysis. None of the patients with repeatedly non-diagnostic results were diagnosed with thyroid cancer at follow-up. CONCLUSION: The prevalence of thyroid cancer in nodules with non-diagnostic results is lower than the malignancy rate in thyroid nodules in general, but not negligible. They should be followed as per guidelines with heightened suspicion for nodules containing calcifications. Nodules with repeatedly non-diagnostic FNA results especially in the absence of calcifications have a low risk of malignancy and may be observed.

Telecare for patients with type 1 diabetes and inadequate glycemic control: a randomized controlled trial and meta-analysis.

OBJECTIVE: To determine the efficacy of telecare (modem transmission of glucometer data and clinician feedback) to support intensive insulin therapy in patients with type 1 diabetes and inadequate glycemic control. RESEARCH DESIGN AND METHODS: Thirty-one patients with type 1 diabetes on intensive insulin therapy and with HbA1c >7.8% were randomized to telecare (glucometer transmission with feedback) or control (glucometer transmission without feedback) for 6 months. The primary end point was 6-month HbA1c. To place our findings in context, we pooled HbA1c change from baseline reported in randomized trials of telecare identified in a systematic review of the literature. RESULTS: Compared with the control group, telecare patients had a significantly lower 6-month HbA1c (8.2 vs. 7.8%, P = 0.03, after accounting for HbA1c at baseline) and a nonsignificant fourfold greater chance of achieving 6-month HbA1c < or =7% (29 vs. 7%; risk difference 21.9%, 95% CI -4.7 to 50.5). Nurses spent 50 more min/patient giving feedback on the phone with telecare patients than with control patients. Meta-analysis of seven randomized trials of adult patients with type 1 diabetes found a 0.4% difference (95% CI 0-0.8) in HbA1c mean change from baseline between the telecare and control groups. CONCLUSIONS: Telecare is associated with small effects on glycemic control in patients with type 1 diabetes on intensive insulin therapy but with inadequate glycemic control.

Ultrasound-guided fine-needle aspiration biopsy of thyroid nodules in patients taking novel oral anticoagulants.

BACKGROUND: Ultrasound-guided fine-needle aspiration biopsy (USGFNAB) is the most accurate form of evaluation for thyroid nodules. Many patients with thyroid nodules who present for USGFNAB are on anticoagulant agents, including the novel oral anticoagulants (NOACs), for stroke prevention in atrial fibrillation or venous thrombosis prophylaxis. SUMMARY: There has been at least one retrospective study describing neck USGFNAB bleeding risks in patients on antithrombotic and/or anticoagulant agents. This study concluded that there was no major bleeding risk or increase in hematoma formation in patients on antithrombotic or anticoagulant agents while undergoing USGFNAB, and there was no need to discontinue these agents prior to the procedure. With the emergence of NOACs, further recommendations should be made for patients on these agents who will be undergoing USGFNAB for thyroid nodules. Currently, there are no published studies regarding patients on NOACs who undergo USGFNAB. CONCLUSIONS: It has previously been established that patients on historical anticoagulant agents do not need to discontinue therapy prior to minor procedures such as needle aspirations or dental procedures. Therefore, in patients currently taking dabigatran, rivaroxaban, or apixaban, it is concluded that it is reasonable and safe to continue the novel oral anticoagulant agents prior to USGFNAB of thyroid nodules without major risk of bleeding. This conclusion is based not only on the fact that minor procedures are considered safe in patients on NOACs, but also because patients on historical anticoagulant agents do not need to discontinue therapy prior to minor procedures.
