Doses of medial rectus muscle recessions for divergence insufficiency-type esotropia.

We evaluated whether doses of bilateral medial rectus recessions greater than Parks's tables yielded superior outcomes for adult-onset divergence insufficiency. Forty-two patients underwent bilateral medial rectus recessions. Dose was analyzed as the average total per muscle (surgery + suture adjustment if performed) and compared with the standard dose tables (based on preoperative distance esodeviation), as difference between dose performed and dose indicated by Parks's tables. Each participant was classified as having received either Parks's dose (within 0.5 mm) or a dose greater than Parks's dose. Success was defined as "rarely" or "never" diplopia in distance straight-ahead gaze and reading. For patients classified as success, the mean difference between actual surgical dose performed and Parks's dose was calculated. Success was 91% (29/32) in those receiving greater than Parks's dose versus 67% (6/9) with Parks's dose (difference = 24%; 95% CI, -5% to 60%). The mean surgical dose was 1.0 mm greater than Parks's tables for the 35 successes (at 10 weeks) versus 0.7 mm greater for the 6 failures (difference = 0.4 mm; 95% CI, -0.2 to 0.9). For medial rectus recessions in adult-onset divergence insufficiency-type esotropia, a surgical dose 1 mm greater than Parks's tables, for each muscle, is a reasonable strategy.

Improving Global Access to Transgender Health Care: Outcomes of a Telehealth Quality Improvement Study for the Air Force Transgender Program.

Purpose: To describe the development of the United States Air Force's (USAF) telehealth program from fall 2017 through fall of 2020 in response to the unique challenges associated with providing care for a global transgender military population. Methods: Telehealth visit completion rates were monitored at time of encounters and through electronic health record reports. Patient satisfaction data were obtained by immediate postvisit survey, across provider care received, logistics of setting up the appointment, and quality of the virtual health system connection. Patient cases highlighting opportunities for transgender telehealth were summarized. Results: Between September 9, 2019 and October 28, 2020, 99 telehealth encounters with video-to-video connection occurred. Twenty-three of the encounters were for gender-affirming hormone therapy, 17 for mental health visits, and 59 for speech therapy. Thirty-five surveys were collected from 20 patients. Overall patients were "satisfied" or "very satisfied" with providers' ability to manage their chief complaint through this modality (average 4.9 out of 5 on 1 to 5 scale with 1 being "very dissatisfied" and 5 being "very satisfied") and "strongly agree" that telehealth is an effective means to accomplish care (average score 4.8 on 1 to 5 scale with 1 being "strongly disagree" and 5 "strongly agree"). Services provided spanned 11 USAF bases worldwide. Conclusions: Telehealth is successful in ensuring ongoing transgender health care services for a global military population. The success of this program may have implications for future military and civilian endeavors to bridge care gaps for transgender patients in resource-poor or distant-site locations.

MASSIVE THYMIC HYPERPLASIA SECONDARY TO GRAVES DISEASE.

OBJECTIVE: Graves disease (GD) has a well-known association with thymic hyperplasia, which is seen histo-logically in up to 38% of patients with GD. However, there have only been approximately 100 documented cases of Graves-associated massive thymic hyperplasia. Potential mechanisms of thymic pathology are reviewed. METHODS: A 24-year-old female presented to the emergency department with dyspnea, palpitations, tachycardia, anxiety, and weight loss. She was evaluated for hyperthyroidism using labs (thyroid-stimulating hormone, free thyroxine, thyroid-stimulating immunoglobulins) and imaging (radioactive iodine uptake [RAIU] scan), leading to treatment with radioiodine. A computed tomography angiogram of the chest was also performed to evaluate for pulmonary embolism given the patient's presenting symptoms. RESULTS: Our patient was found to have undetectable thyroid-stimulating hormone, elevated free thyroxine (2.9 ng/dL), and elevated thyroid-stimulating immunoglobulins (399%). Diagnosis of GD was confirmed on RAIU scan. The computed tomography chest angiogram demonstrated a significant anterior mediastinal mass (7.9 × 6.9 × 6.3 cm). Treatment with radioiodine led to reduction of the mass by 76% in volume. CONCLUSION: While the patient's thyroid labs and RAIU scan were consistent with GD, the presence of massive thymic hyperplasia was atypical. However, the resolution of thymic hyperplasia after radioiodine therapy, without the use of thymectomy, was similar to other reported cases.

IMPACT OF STRUCTURED INSULIN ORDER SETS ON INPATIENT HYPOGLYCEMIA AND GLYCEMIC CONTROL.

Objective: In hospitalized patients, glycemic excursions outside recommended glycemic targets have been associated with increased morbidity and mortality. Despite recommendations to avoid use of correctional insulin alone for managing hyperglycemia, this approach remains common. We performed a quality improvement project aimed at both reducing hypoglycemic events and promoting increased use of basal insulin by updating our insulin order sets to reflect clinical practice guideline recommendations. Methods: Brooke Army Medical Center correctional insulin order sets were modified to reflect higher treatment thresholds and targets, and a basal insulin order was added with a recommended weight-based starting dose. Pre- and postintervention analyses were performed. Patients were included if they were prescribed subcutaneous insulin during their hospital stay. The following outcomes were measured: (1) glucose levels, and (2) prescriptions for basal insulin. Results: A significant reduction in hypoglycemia events was noted following the intervention (glucose <70 mg/dL: 9.2% pre-intervention vs. 8.8% postintervention; glucose <55 mg/dL: 4.2% pre-intervention vs. 2.2% postintervention). When excluding patients that were ordered correctional insulin alone but did not receive a dose, an increase in basal insulin use was seen (50% pre-intervention vs. 61% postintervention). Rates and severity of hyperglycemia (glucose >180 mg/dL) remained unchanged. Conclusion: The alteration in insulin order set parameters resulted in a significant reduction in hypoglycemia without significant increases in hyperglycemia. Although basal insulin use increased, optimal dosing recommendations were not often utilized. Further interventions are necessary to reduce hyperglycemia.

Leadership Training in Graduate Medical Education: Time for a Requirement?

INTRODUCTION: The need for all physicians to function as leaders in their various roles is becoming more widely recognized. There are increasing opportunities for physicians at all levels including Graduate Medical Education (GME) to gain leadership skills, but most of these opportunities are only for those interested. Although not an Accreditation Council for Graduate Medical Education (ACGME) requirement, some US graduate medical education programs have incorporated leadership training into their curricula. Interestingly, the Royal College of Physicians and Surgeons of Canada adopted the Leader role in its 2015 CanMEDS physician training model and requires leadership training. We sought to understand the value of a leadership training program in residency in our institution. MATERIALS AND METHODS: Our 2017 pilot leadership training program for senior military internal medicine residents consisted of four one-hour sessions of mini-lectures, self-assessments, case discussions, and small group activities. The themes were: Introduction to Leadership, Emotional Intelligence, Teambuilding, and Conflict Management. Participants were given an 18-question survey (14 Likert scale multiple-choice questions and 4 open-ended response questions) to provide feedback about the course. The Brooke Army Medical Center Institutional Review Board approved this project as a Quality Improvement effort. RESULTS: The survey response rate was 48.1% (26 of 54). The majority of respondents (84.6%) agreed the leadership training sessions were helpful and relevant. Following the sessions, 80.8% saw a greater role for physicians to function as leaders. Most (88.4%) agreed that these sessions helped them understand the importance of their roles as leaders, with 80.8% feeling more empowered to be leaders in their areas, 76.9% gaining a better understanding of their own strengths and weaknesses as leaders, and 80.8% feeling better prepared to meet challenges in the future. After exposure to leadership training, 73.1% indicated a plan to pursue additional leadership development opportunities. All respondents agreed that internists should be able to lead and manage a clinical team, and every respondent agreed that leadership principles should be taught in residency. CONCLUSIONS: This pilot project supports the premise that leadership training should be integrated into GME. Initial results suggest training can improve leadership skills and inspire trainees to seek additional leadership education. Moreover, much like the published literature, residents believe they should learn about leadership during residency. While more effort is needed to determine the best approach to deliver and evaluate this content, it appears even small interventions can make a difference. Next steps for this program include developing assessment tools for observation of leadership behaviors during routine GME activities, which would allow for reinforcement of the principles being taught. Additionally, our experience has led our institution to make leadership training a requirement in all of our GME programs, and we look forward to reporting future progress. Finally, an ACGME requirement to incorporate leadership training into GME programs nationwide would prove useful, as doing so would reinforce its importance, accelerate implementation, and expand knowledge of best approaches on a national level.

A Randomized Trial of Binocular Dig Rush Game Treatment for Amblyopia in Children Aged 7 to 12 Years.

PURPOSE: To compare visual acuity (VA) improvement in children aged 7 to 12 years with amblyopia treated with a binocular iPad game plus continued spectacle correction vs. continued spectacle correction alone. DESIGN: Multicenter randomized clinical trial. PARTICIPANTS: One hundred thirty-eight participants aged 7 to 12 years with amblyopia (33-72 letters, i.e., approximately 20/200 to 20/40) resulting from strabismus, anisometropia, or both. Participants were required to have at least 16 weeks of optical treatment in spectacles if needed or demonstrate no improvement in amblyopic-eye visual acuity (VA) for at least 8 weeks prior to enrollment. METHODS: Eligible participants (mean age 9.6 years, mean baseline VA of 59.6 letters, history of prior amblyopia treatment other than spectacles in 96%) were randomly assigned to treatment for 8 weeks with the dichoptic binocular Dig Rush iPad game (prescribed for 1 hour per day 5 days per week) plus spectacle wear if needed (n = 69) or continued spectacle correction alone if needed (n = 69). MAIN OUTCOME MEASURES: Change in amblyopic-eye VA from baseline to 4 weeks, assessed by a masked examiner. RESULTS: At 4 weeks, mean amblyopic-eye VA letter score improved from baseline by 1.3 (2-sided 95% confidence interval [CI]: 0.1-2.6; 0.026 logMAR) with binocular treatment and by 1.7 (2-sided 95% CI: 0.4-3.0; 0.034 logMAR) with continued spectacle correction alone. After adjusment for baseline VA, the letter score difference between groups (binocular minus control) was -0.3 (95% CI: -2.2 to 1.5, P = 0.71, difference of -0.006 logMAR). No difference in letter scores was observed between groups when the analysis was repeated after 8 weeks of treatment (adjusted mean: -0.1, 98.3% CI: -2.4 to 2.1). For the binocular group, adherence data from the iPad indicated that slightly more than half of the participants (58% and 56%) completed >75% of prescribed treatment by the 4- and 8-week visits, respectively. CONCLUSIONS: In children aged 7 to 12 years who have received previous treatment for amblyopia other than spectacles, there was no benefit to VA or stereoacuity from 4 or 8 weeks of treatment with the dichoptic binocular Dig Rush iPad game.

Getting New Test Results to Patients.

: New diagnostic results are constantly arriving to outpatient practices. It is imperative to effectively communicate these results and their implications to patients. METHODS: We surveyed 100 patients and our clinic personnel to assess opinions regarding methods of communication in common scenarios. RESULTS: Response rate was 79% from patients and 75% from clinic personnel. Most patients thought letters were an appropriate way to receive normal test results (83%). They also felt medical-technician calls were appropriate for normal results (88%), medication dose changes (75%), or need for additional studies (71%). Respondents considered nurse calls acceptable in most scenarios except for new diagnoses of cancer or need for surgery; the consensus was that physicians should directly communicate to patients in these situations. CONCLUSIONS: Providers should take the time to discuss results with patients that lead to significant interventions, but employ support staff to disseminate information about normal results, medication dose changes, and need for additional diagnostic testing.

Analysis of current thyroid function test ordering practices.

RATIONALE: Current guidelines recommend thyroid stimulating hormone (TSH) alone as the best test to detect and monitor thyroid dysfunction, yet free thyroxine (FT4) and free triiodothyronine (FT3) are commonly ordered when not clinically indicated. Excessive testing can lead to added economic burden in an era of rising healthcare costs, while rarely contributing to the evaluation or management of thyroid disease. OBJECTIVE: To evaluate our institution's practice in ordering thyroid function tests (TFTs) and to identify strategies to reduce inappropriate FT4 and FT3 testing. METHODS: A record of all TFTs obtained in the San Antonio Military Health System during a 3-month period was extracted from the electronic medical record. The TFTs of interest were TSH, FT4, thyroid panel (TSH + FT4), FT3, total thyroxine (T4), and total triiodothyronine (T3). These were categorized based on the presence or absence of hypothyroidism. RESULTS: Between August 1 and October 31, 2016, there were 38 214 individual TFTs ordered via 28 597 total laboratory requests; 11 486 of these requests were in patients with a history of hypothyroidism. The number (percent) of laboratory requests fell into these patterns: TSH alone 14 919 (52.14%), TSH + FT4 7641 (26.72%), FT3 alone 3039 (10.63%), FT4 alone 1219 (4.26%), TSH + FT4 + FT3 783 (2.74%), and others 996 (3.48%); 36.0% of TFTs ordered were free thyroid hormones. Projected out to a year, using Department of Defense laboratory costs, $317 429 worth of TFTs would be ordered, with free thyroid hormone testing accounting for $107 720. CONCLUSION: Inappropriate ordering of free thyroid hormone tests is common. In an era of rising healthcare costs, inappropriate thyroid function testing is an ideal target for efforts to reduce laboratory overutilization, which in our system, could save up to $120 000 per year. Further evaluation is needed to determine strategies that can reduce excessive thyroid hormone testing.

The importance of pheochromocytoma case detection in patients with neurofibromatosis type 1: A case report and review of literature.

Neurofibromatosis type 1 is a complex, multi-system genetic disorder that is associated with an increased prevalence of pheochromocytoma and paraganglioma compared to the general population, 1.0%-5.7% versus 0.2%-0.6%, respectively. A delay in pheochromocytoma and paraganglioma diagnosis or undiagnosed pheochromocytoma and paraganglioma, as seen in normotensive and asymptomatic patients, may portend a significant morbidity and mortality risk due to excess catecholamine secretion. Currently, there are no generally accepted guidelines of screening for pheochromocytoma and paragangliomas in asymptomatic individuals of this population with approaches and practices varying considerably between physicians. Emerging data suggest benefit in routine pheochromocytoma and paraganglioma screening of all individuals with neurofibromatosis type 1. Herein, we present a case to highlight how routine case detection screening would have identified pheochromocytoma earlier in an active duty military member.

Leadership Training in Endocrinology Fellowship? A Survey of Program Directors and Recent Graduates.

CONTEXT: There is growing recognition that more physician leaders are needed to navigate the next era of medicine. OBJECTIVE: To determine current opinions about leadership training in endocrinology fellowship programs. DESIGN/PARTICIPANTS: Twenty-seven-question survey addressing various aspects of leadership training to current nationwide fellowship program directors (PDs) and fellowship graduates since 2010. INTERVENTION: In partnership with the Endocrine Society, the electronic survey was advertised primarily via direct e-mail. It was open from March through July 2016. MAIN OUTCOME MEASURES: The survey addressed leadership traits, importance of leadership training, preferred timing, and content of leadership training. RESULTS: Forty-six of 138 PDs (33.3%) and 147 of 1769 graduates (8.3%) completed the survey. Among PDs and graduates, there was strong agreement (>95%) about important leadership characteristics, including job knowledge, character traits, team-builder focus, and professional skills. PDs (64.5%) and graduates (60.8%) favored teaching leadership skills during fellowship, with PDs favoring mentoring/coaching (75.0%), direct observation of staff clinicians (72.5%), and seminars (72.5%). Graduates favored a variety of approaches. Regarding topics to include in a leadership curriculum, PDs responded that communication skills (97.5%), team building (95.0%), professional skills (90.0%), clinic management (87.5%), strategies to impact the delivery of endocrinology care (85.0%), and personality skills (82.5%) were most important. Graduates responded similarly, with >80% agreement for each topic. Finally, most PDs (89%) expressed a desire to incorporate more leadership training into their programs. CONCLUSIONS: Our survey suggests a need for leadership training in endocrinology fellowships. More work is needed to determine how best to meet this need.

Synopsis of the 2017 U.S. Department of Veterans Affairs/U.S. Department of Defense Clinical Practice Guideline: Management of Type 2 Diabetes Mellitus.

DESCRIPTION: In April 2017, the U.S. Department of Veterans Affairs (VA) and the U.S. Department of Defense (DoD) approved a joint clinical practice guideline for the management of type 2 diabetes mellitus. METHODS: The VA/DoD Evidence-Based Practice Work Group convened a joint VA/DoD guideline development effort that included a multidisciplinary panel of practicing clinician stakeholders and conformed to the Institute of Medicine's tenets for trustworthy clinical practice guidelines. The guideline panel developed key questions in collaboration with the ECRI Institute, which systematically searched and evaluated the literature through June 2016, developed an algorithm, and rated recommendations by using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. RECOMMENDATIONS: This synopsis summarizes key features of the guideline in 7 areas: patient-centered care and shared decision making, glycemic biomarkers, hemoglobin A1c target ranges, individualized treatment plans, outpatient pharmacologic treatment, glucose targets for critically ill patients, and treatment of hospitalized patients.

Overview and Discussion of the 2017 VA/DoD Clinical Practice Guideline for the Management of Type 2 Diabetes Mellitus in Primary Care.

The 2017 diabetes mellitus guidelines emphasize shared decision making, dietary changes, and HbA1c target range for optimal control of diabetes mellitus.

EVALUATION OF TOTAL DAILY DOSE AND GLYCEMIC CONTROL FOR PATIENTS TAKING U-500 REGULAR INSULIN ADMITTED TO THE HOSPITAL.

OBJECTIVE: Patients using U-500 regular insulin are severely insulin resistant, requiring high doses of insulin. It has been observed that a patient's insulin requirements may dramatically decrease during hospitalization. This study sought to systematically investigate this phenomenon. METHODS: We performed a retrospective chart review of patients with U-500 insulin outpatient regimens who were admitted to the San Antonio Military Medical Center over a 5-year period. Each patient's outpatient total daily dose (TDD) of insulin was compared to the average inpatient TDD. The outpatient estimated average glucose (eAG) was calculated from the glycated hemoglobin (HbA1c) and compared to the average inpatient glucose. RESULTS: There were 27 patients with a total of 62 separate admissions. The average age was 64.4 years, with a mean body mass index of 38.9 kg/m2 and eAG of 203 mg/dL (HbA1c, 8.7%, 71.6 mmol/mol). All patients were converted from U-500 to U-100 upon admission. The average inpatient TDD of insulin was 91 units, versus 337 units as outpatients (P<.001). Overall, 89% of patients received ≤50% of their outpatient TDD. The average inpatient glucose was slightly higher than the outpatient eAG, 234 mg/dL versus 203 mg/dL (P = .003). CONCLUSION: U-500 insulin is prone to errors in the hospital setting, so conversion to U-100 insulin is a preferred option. Despite a significant reduction in insulin TDD, these patients had clinically similar glucose levels. Therefore, patients taking U-500 insulin as an outpatient can be converted to a U-100 basal-bolus regimen with at least a 50% reduction of their outpatient TDD.

Functional brain networks and white matter underlying theory-of-mind in autism.

Human beings constantly engage in attributing causal explanations to one's own and to others' actions, and theory-of-mind (ToM) is critical in making such inferences. Although children learn causal attribution early in development, children with autism spectrum disorders (ASDs) are known to have impairments in the development of intentional causality. This functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) study investigated the neural correlates of physical and intentional causal attribution in people with ASDs. In the fMRI scanner, 15 adolescents and adults with ASDs and 15 age- and IQ-matched typically developing peers made causal judgments about comic strips presented randomly in an event-related design. All participants showed robust activation in bilateral posterior superior temporal sulcus at the temporo-parietal junction (TPJ) in response to intentional causality. Participants with ASDs showed lower activation in TPJ, right inferior frontal gyrus and left premotor cortex. Significantly weaker functional connectivity was also found in the ASD group between TPJ and motor areas during intentional causality. DTI data revealed significantly reduced fractional anisotropy in ASD participants in white matter underlying the temporal lobe. In addition to underscoring the role of TPJ in ToM, this study found an interaction between motor simulation and mentalizing systems in intentional causal attribution and its possible discord in autism.

Longitudinal follow-up of hypermetropic children identified during preschool vision screening.

PURPOSE: Early childhood hypermetropia is an important risk factor for the development of amblyopia and esotropia. Understanding the natural history of these complications aids in management decisions. METHODS: A retrospective observational review was undertaken of 149 patients referred from a preschool photoscreening program who were determined to have hypermetropia of >or=+3.75 D spherical equivalent on criterion standard examination and were treated/followed by one group of academic pediatric ophthalmologists. The prevalence and incidence of accommodative esotropia and amblyopia were determined. RESULTS: At presentation 19% of hypermetropic children had amblyopia, 32% had esotropia, and 13% had both. Follow-up data of 108 patients during a mean of 40 months showed that 20 (24%) of 83 initially nonamblyopic patients developed amblyopia and that 22 (33%) of 67 initially nonstrabismic patients developed accommodative esotropia. Of patients initially managed with observation, 38% (6 of 16) developed amblyopia, and 31% (5 of 16) developed accommodative esotropia as compared with 21% (14 of 67) and 33% (17 of 51), respectively, for those given full or partial refractive correction. For patients without amblyopia or strabismus at presentation, only 20% developed amblyopia and 35% esotropia. Strabismic patients responded well to treatment, with no cases developing partially accommodative strabismus requiring surgery during follow-up. CONCLUSIONS: In this case series we found a high prevalence of amblyopia and strabismus. The results support the importance of early preschool vision screening and spectacle correction of moderate to high hypermetropia (>+3.50 D) to reduce the risk of amblyopia, although more research is needed.

Corneal ulceration due to vitamin A deficiency in Zellweger syndrome.

We report a case of vitamin A deficiency and secondary corneal ulcer in an infant with Zellweger syndrome. A 7-month-old infant with failure to thrive and malnutrition developed a corneal ulcer. Fortified antibiotic eye drops were administered without improvement. Vitamin A deficiency was suspected and confirmed. Supplementation with oral vitamin A decreased corneal opacification. Zellweger syndrome was later diagnosed. Vitamin A deficiency should be considered in the differential diagnosis of nonhealing corneal ulcers in children, especially those with systemic syndromes and failure to thrive.
