Adrenal incidentalomas (AIs) are common incidental findings in medical practice with clinical significance. Although most AIs are nonsecretory and nonmalignant, they require a short course of follow-up over one to two years to rule out malignancy or hormonal secretion according to clinical practice guidelines. However, this can result in some adrenocortical carcinomas (ACCs) being missed if they transform at a later stage or evolve slowly. Here, we report one such case of an AI, which although remained indolent, eventually transformed into an ACC many years after the initial detection., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Kohli et al.)

Primary hyperparathyroidism (PHPT) is the most common etiology of hypercalcemia in the ambulatory setting and usually presents with an intact parathyroid hormone (PTH) level that is elevated or inappropriately near the upper limit of the laboratory reference range. However, PHPT with low-normal PTH level is reported in the peer-reviewed literature, and this atypical presentation may delay diagnosis of PHPT. We present a case of PHPT with persistently low-normal PTH level in which the PTH dependence of hypercalcemia was demonstrated by the response to treatment with the calcimimetic agent cinacalcet., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Bandaru et al.)

Purpose: Adherence rates to published guidelines for diabetic retinopathy (DR) screening is between 35 and 60%. We evaluate a teleretinal DR screening (TDRS) program in a private practice vertically integrated system to increase compliance with retinal screening., Methods: A retrospective pre-post intervention longitudinal study was conducted in a private endocrinology practice using TDRS as the primary intervention. Compliance rates for diabetic retinal screening were compared between December 31, 2016 and December 31, 2018., Results: A total population of 3479 patients were evaluated. Retinal screening compliance improved from 56.5% of patients (1964) pre-intervention to 59.3% of patients (2064) post intervention. The McNemar test was used for statistical analysis and found the change significant (p = 0.004)., Conclusions: TDRS as an adjunct tool in a private practice endocrinology office significantly improved screening rates and can increase access to recommended diabetic eye care. However, the improvement in screening rates was smaller than other types of practice settings. We explore some of the unique challenges to implementation of TDRS in private practice settings., (© 2020 The Authors.)

BACKGROUND Sarcoidosis is a systemic disease that can affect any organ, including the liver. It is manifested by the presence of non-caseating granulomas within involved organs, most commonly the pulmonary, lymphatic, and hepatic system. Unlike pulmonary or lymphatic involvement, hepatic involvement is usually asymptomatic and it is underdiagnosed. Here, we report a case of a patient with a history of pulmonary sarcoidosis who developed hepatic sarcoidosis. CASE REPORT 68-year-old female with pulmonary sarcoidosis with a 2-week history of severe abdominal pain and epigastric tenderness presented to our center. Abdominal magnetic resonance imaging (MRI) demonstrated mild hepatic fibrosis and cirrhosis. A thorough workup was performed including a liver biopsy which showed chronic non-necrotizing granulomas consistent with sarcoidosis. She was started on prednisone and subsequently improved. The patient was symptom-free on follow-up 1 month later. CONCLUSIONS The majority of patients with hepatic sarcoidosis are usually asymptomatic, with only 5-30% presenting with abdominal pain, jaundice, nausea, vomiting, and hepatosplenomegaly. In rare cases, hepatic sarcoidosis can lead to cholestasis, portal hypertension, cirrhosis, or Budd-Chiari syndrome. Treatment with steroids is the mainstay of therapy; however, in severe cases, patients may require liver transplantation. This case report demonstrates that hepatic sarcoidosis is a serious condition, and if not treated, can lead to portal hypertension and cirrhosis. In patients with sarcoidosis, early detection and longitudinal follow-up is important in preventing overt liver failure.

Introduction Basal/bolus insulin (BBI) is superior to sliding scale insulin (SSI) for diabetic patients admitted to hospital general medicine and surgery services, but little has been published on strategies to promote the utilization of BBI by resident physicians. New approaches that promote the effective management of hyperglycemia in hospitals need to be developed. Materials and methods  A prospective study with historical controls was conducted to evaluate the impact of a pocket insulin dosing guide on the diabetes management practices of internal medicine resident physicians at the Southern Illinois University (SIU) School of Medicine, rotating on general medicine. The primary endpoint was the proportion of patients with preexisting diabetes mellitus managed with BBI. Pocket insulin dosing guides with instructions for initiating BBI and daily insulin adjustments were provided to all internal medicine residents in November 2010. BBI utilization rates were monitored over the period November 2010-February 2011 and were compared to the corresponding four-month period over the previous academic year (November 2009-February 2010), which was before the pocket insulin dosing guides were introduced (pilot study). Internal medicine house staff insulin ordering practices were subsequently evaluated for a 12-month period between October 2010-November 2011, with November 2009-October 2010 used as a historical control (study extension). New interns that were starting their residency training from July 2011 were provided with the pocket insulin dosing guides and given the same instructions as the previous academic year's resident physicians. Results  Historical controls (N = 579) and study patients (N = 584) were well matched, with the exception of the male gender (49% vs. 41%, P = 0.01) and diet-managed diabetes (10.5% vs. 6.4%, P = 0.01). During the pilot study, BBI increased from 12.8% of all resident insulin orders in November 2010 to 58.1% of all orders in February 2011 (P < 0.01 for trend). Overall, BBI as a proportion of all resident insulin orders was 35.7% during the pilot phase, which is a six-fold increase over the previous academic year (6%), and was also statistically significant (P<0.01). For the 12-month period of evaluation between November 2010 and October 2011, internal medicine residents ordered BBI for 41.9% of diabetes patients, compared to 16.7% of patients in the 12 months before the pocket insulin dosing guide was introduced (P < 0.01). Patients managed with BBI had higher blood glucose values at admission than patients managed with SSI (195 ± 95 mg/dL vs. 178 ± 83 mg/dL, P < 0.01) and experienced a 41 mg/dL improvement in mean daily capillary blood glucose (CBG) as compared to no change for patients managed with SSI (P = 0.01 for trend). The rate of hypoglycemia, defined as CBG < 70 mg/dL, was 2.4% for both BBI and SSI managed patients (P = 0.93). Conclusion The SIU pocket insulin dosing guide significantly increased the utilization of BBI, decreased SSI orders, and improved hospital glycemic control for patients with diabetes mellitus. However, over half of the general medicine patients were still managed with SSI despite the pocket insulin dosing guides. Conversion of the insulin dosing guide to a smartphone app might improve utilization of the protocol and further increase the use of BBI for inpatient diabetes management by internal medicine house staff., Competing Interests: The authors have declared that no competing interests exist.

Influenza A associated with rhabdomyolysis has become more commonly recognized in recent years. It requires prompt recognition and treatment in order to prevent heme pigment-induced acute kidney injury. Here we report a 50-year-old female without a significant past medical history who presented with a one-week history of fevers, chills, fatigue, and generalized body aches. She was on no prior medication. Laboratory studies were significant for leukocytosis and elevated creatinine kinase up to a peak of 28,216 IU/L. Rapid influenza antigen testing was positive for influenza A virus. The patient was diagnosed with influenza A-induced rhabdomyolysis. According to our literature review, we are the first to report a case of influenza A-induced rhabdomyolysis in the 2017-2018 flu season. This case highlights the importance of considering rhabdomyolysis as a manifestation of an influenza infection., Competing Interests: The authors have declared that no competing interests exist.

Acute pericarditis as a presenting sign of adrenal insufficiency is rarely reported. We present a rare case that highlights pericarditis as a clinical presentation of secondary adrenal insufficiency later complicated by cardiac tamponade. A 44-year-old lady who presented to the hospital with a one-day history of pleuritic chest pain and shortness of breath. In the emergency room, she had a blood pressure of 70/35 mmHg. Laboratory evaluation revealed white blood cell count of 16.08 k/cumm with neutrophilia, normal renal function and elevated troponin (0.321 ng/mL, normal 0.000-0.028). An electrocardiogram (EKG) showed sinus tachycardia, low voltage, PR suppression and ST changes consistent with acute pericarditis. Echocardiogram showed small pericardial effusion without tamponade physiology. Infectious workup was negative; she was thought to have acute adrenal insufficiency likely secondary to viral pericarditis. We treated the patient with high dose nonsteroidal anti-inflammatory drugs (NSAIDS) and hydrocortisone. Three weeks later, she presented to emergency room with complaints of persistent nausea, vomiting, chills, weakness. Her blood pressure was 49/23 mmHg. Random serum cortisol level was <1.2 mcg/dl (normal A.M. specimens 3.7-19.4 mcg/dl). Echocardiogram showed loculated pericardial fluid adjacent to the right ventricle with echocardiographic evidence of tamponade. Emergent pericardiocentesis yielded 250 ml of straw color fluid. Blood pressure improved after the procedure. The patient was initially started on IV stress dose steroids, but following clinical stabilization, hydrocortisone was switched to a physiological dose of 15 mg in am and 10 mg in pm. Although the mechanism of pericarditis in adrenal failure is unknown, this clinical presentation may help early diagnosis of adrenal failure and pericarditis. Early recognition and prompt treatment of this rare presentation are critical to prevent morbidity and mortality., Competing Interests: The authors have declared that no competing interests exist.

Background: Increased blood glucose is associated with adverse clinical outcomes among patients with major illnesses. This study examined the association between blood glucose and adverse outcomes among hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease, for which limited prior data were available., Methods: We studied a cohort of 209 hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease. Univariate analyses and multivariate logistic regression analyses with backward elimination method were performed to evaluate factors associated with in-hospital complications, length of hospitalization, 30-day hospital readmission, and 90-day all-cause mortality., Results: Multivariate logistic regression analysis with backward elimination method revealed that lower blood glucose and age at hospital admission were the most significant risk factors for in-hospital complication. Received respiratory support and in-hospital complications were the most significant risk factors for the length of hospitalization. There were no significant risk factors associated with 30-day hospital readmission and 90-day all-cause mortality., Conclusion: The analyses failed to reveal significant associations between higher blood glucose levels and adverse outcomes. We showed that lower glucose levels (hypoglycemia) results in higher risk for in-hospital complications. In-hospital complications results in longer length of hospitalization, which implies that lower glucose levels (hypoglycemia) indirectly may result in longer length of hospitalization. More studies are needed to better clarify the cause for these associations.
