Hepatic Encephalopathy Secondary to Non-cirrhotic Portosystemic Shunt.

Hepatic encephalopathy is uncommon in the absence of cirrhosis. We report a 71-year-old woman who presented with altered mental status in the setting of hyperammonemia for the second time in 6 months. Magnetic resonance imaging of the abdomen revealed an uncommon portosystemic shunt involving an enlarged posterior branch of the right portal vein and an accessory right hepatic vein, with no features of cirrhosis. Appropriate management of these patients with ammonia-lowering therapy can reduce repeat episodes and improve quality of life. This case demonstrates the importance of diagnosing non-cirrhotic hepatic encephalopathy in patients with altered mental status.

Pernicious Anemia Unveiled: Unusual Hemolytic Complications and Clinical Implications.

Pernicious anemia (PA) is an autoimmune condition resulting in impaired vitamin B12 absorption that commonly presents with gastritis and neurological symptoms. In rare cases, associated vitamin B12 deficiency can contribute to significant red blood cell lysis, and patients can present with PA-induced pseudo-thrombotic microangiopathy (TMA) hemolytic anemia. This case describes a 59-year-old male presenting with a two-week history of gastrointestinal pain with bleeding who had anemia and hemodynamic instability on initial evaluation. After the endoscopy/colonoscopy did not reveal any active sources of bleeding and packed red blood cells failed to stabilize the patient, it was found that he had low serum B12 with anti-intrinsic factor and anti-parietal cell antibodies. A coordinated clinical approach, including parenteral cyanocobalamin and daily oral folic acid supplementation, stabilized the patient, highlighting the importance of distinguishing PA-induced pseudo-TMA from true TMA hemolytic anemia.

"I Am the Last Priority": Factors Influencing Diabetes Management Among South Asian Caregivers in Peel Region, Ontario.

OBJECTIVE: In this study, we aimed to identify sociocultural and systemic factors influencing diabetes management among South Asian (SA) caregivers in Peel Region, Ontario. METHODS: Twenty-one semistructured interviews were conducted with SA caregivers using a qualitative descriptive design. Data were analyzed using thematic analysis and intersectionality analysis. RESULTS: Themes identified included 1) prioritizing family caregiving over diabetes self-management; 2) labour market impacts on diabetes self-management; and 3) challenges navigating Canadian health and social service systems. SA caregivers described social, economic, and systemic challenges impacting type 2 diabetes management. Systemic factors influencing diabetes management included discrimination and inequities in labour policies and lack of social and health resources funding. Recommendations by caregivers included whole-family, community-based, culturally tailored approaches to diabetes prevention and management strategies. CONCLUSIONS: Providing support with system navigation, encouraging family-based approaches, and addressing the social determinants of health could be beneficial for supporting SA families with diabetes management and prevention.

The Prevalence of Internet Use as a Source of Information Among Patients With Hypertension.

Background and objective The incidence of hypertension is growing at an alarming rate globally. In the United States, nearly half of the adult population suffers from hypertension, a disease potentially associated with long-term dire consequences and comorbidities. While Internet access has proliferated, and free Internet-based education resources for healthy lifestyles have exponentially increased over the past two decades, little is known about whether Internet-based information can be or is used as a self-learning tool for hypertension management in a community setting. With almost no published data, if and to what degree Internet-based, self-directed learning tools are used for hypertension management needs to be assessed. In light of this, we aimed to evaluate the prevalence of Internet use as a source of information in patients with known diagnoses of hypertension who presented to our Internal Medicine clinic at Texas Tech University Health Sciences Center, El Paso. Materials and methods We conducted a single-center, cohort-based observational study at our teaching hospital's internal medicine clinic. A survey questionnaire was distributed to all adults aged more than 18 years with a known diagnosis of hypertension. Consent for participation was obtained from all participants. Of the total studied population, 93.6% (190/203) were of Hispanic descent. Moreover, 67.5% (137/203) identified as female. Of note, 22.7% (46/203) reported using the Internet to learn about hypertension. Internet users were younger, with a mean age of 61.4 years compared to 68.7 (p=0.02) years for non-Internet users, attended institutions of a higher grade of education, and mostly received information regarding hypertension from their families (91.3% vs 2.5%, p<0.001). While most patients used the Internet for making treatment decisions and were satisfied with their choices, more than a quarter felt confused and anxious after using Internet-based resources. Results Most patients in the study were found to not use the Internet as a resource tool for hypertension management (157/203; 77.3%). Among the 22.7% of patients who used the Internet for hypertension management, the most commonly utilized resource was Google.com, as an initial step to hypertension research (26/46, 58.6%, p<0.001), followed by multiple resources within a predetermined list on the provided survey (14/46, 30.4%). The survey also assessed the reasons for using Internet-based resources, with the primary reason being evaluating treatment options (19/46, 41.5%), followed by developing coping skills (13/46, 28.2%), and lastly aiding in decision-making (10/46, 21.5%). Conclusions Internet-based educational tools are mushrooming as the Internet is becoming more pervasive. This study shows that within this predominant Hispanic population, nearly one-quarter of patients with hypertension are using Internet-based, self-learning tools. This highlights a slow shift in medical education which providers have to be prepared for as patients will be using these tools as secondary information sources for medical decision-making more frequently going forward. Further studies need to be conducted to evaluate the current and longitudinal impact of these new information sources.

Periampullary Diverticula Causing Recurrent Pancreatitis: A Case Report.

Acute p-ancreatitis (AP) is increasingly rising globally, especially among elderly populations. In many cases, AP can progress to chronic pancreatitis (CP) and cause damage to the pancreas. Common causes of AP include gallstones and alcoholic injury, but periampullary diverticula (PAD) have emerged as a complex etiology. PADs are rare bowel-filled outpouchings located near the main papilla or common bile duct (CBD). In this study, we present a 66-year-old female with recurrent pancreatitis that is caused by a PAD. Due to the paucity of information regarding the management of PADs, we hope this case highlights the need to advance treatment options in this area.

Spontaneous Tumor Lysis Syndrome Secondary to Metastatic Small Cell Lung Cancer.

Tumor lysis syndrome (TLS) is an oncology emergency caused by the lysis of tumor cells that releases cell contents into the blood. TLS is typically associated with leukemia following the initiation of chemotherapy. Spontaneous TLS has been seen in hematologic malignancies, but the incidence of spontaneous TLS in solid tumors is rare, and only nine cases have been reported in small cell lung carcinoma. We present a case of a patient who presented with severe metabolic acidosis and electrolyte abnormalities consistent with TLS. At presentation, our patient was found to have small cell lung carcinoma with metastasis to the liver. This patient was managed with bicarbonate, rasburicase, allopurinol, and calcium replacement and started on continuous renal replacement therapy, but unfortunately was transitioned to comfort care and passed away. Risk factors for spontaneous TLS include bulky disease, elevated lactate dehydrogenase, elevated white blood cell counts, renal compromise, and abdominal organ involvement. The most common laboratory findings for TLS include metabolic acidosis and hyperuricemia, hyperphosphatemia, hyperkalemia, and hypocalcemia. Cases of spontaneous TLS, however, have been noted to have smaller elevations in phosphate levels. Spontaneous TLS is a rare but potentially fatal complication that can be seen in small cell lung carcinoma.

A rare case of AIDS co-infected with COVID-19 presenting with disseminated Herpes zoster complicated with CMV and Varicella zoster virus meningoencephalitis.

During the COVID-19 pandemic, numerous co-infections have been reported, with some studies indicating that patients with HIV/AIDS have worse outcomes when co-infected with COVID-19. Here, we present the case of a young adult male who presented with disseminated Varicella and was simultaneously diagnosed with AIDS and COVID-19 virus with several infection-related complications.  A 25-year-old African-American male presented to the Emergency Department with vesicular, blistering rashes in multiple dermatomes including his eyelids. The screening test in the ED was positive for COVID-19. Given his high-risk sexual history, he was tested for HIV which returned positive with a CD4 count of zero. He was started on IV antivirals for disseminated varicella with zoster ophthalmicus. The patient was intubated for worsening respiratory failure and required intensive care. During the hospital course, he developed worsening encephalopathy and CSF analysis was positive for CMV and VZV. The patient has a prolonged hospital stay and exhibited evidence of infectious CNS vasculitis and HIV myelopathy. Anti-retroviral therapy was started after the acute period and the patient showed slow but definite clinical improvement. To the best of our knowledge, this is the first case report of a patient with AIDS with COVID-19 and disseminated VZV and with multiple complex infection-related complications.

Service Provider Perspectives on Exploring Social Determinants of Health Impacting Type 2 Diabetes Management for South Asian Adults in Peel Region, Canada.

OBJECTIVES: Individuals from South Asian communities are known to have a higher likelihood of developing type 2 diabetes (T2D), which is often attributed to individual lifestyle and behavioural factors. This focus on individual responsibility can position communities as complicit in their illness, compounding stigmatization and systemic discrimination. In this article, we explore the social determinants of health (SDOH) that influence health behaviours among South Asian adults with T2D from a service provider's perspective. METHODS: Using a qualitative descriptive design, we conducted semistructured interviews with 12 community, social and health-care service providers. We used thematic analysis and the analytical concept of intersectionality to explore how different social locations and SDOH impact T2D management for South Asian adults. RESULTS: Three themes were identified: 1) managing challenges with settlement process, labour policies and job market disparities take priority over T2D management; 2) poor working conditions and low socioeconomic status reduce access to health care and medication; and 3) there are social, economic and cultural barriers to implementing diet and exercise recommendations. CONCLUSIONS: Service providers identified social, economic and systemic factors as influencing the higher prevalence of T2D among South Asian individuals. They also identified their important roles in providing culturally appropriate supports to address SDOH and described advocacy for changes to policies and practices that reinforce systemic racism. The providers further suggested that more equitable employment policies and practices are needed to address the systemic factors that contribute to the higher risk of T2D among South Asian adults in the Peel Region.

An Exploratory Screening Study for Type 2 Diabetes in Hospitalized Adult Medicine Patients.

OBJECTIVES: Literature from stroke and cardiac hospital admissions demonstrate a higher prevalence of undiagnosed type 2 diabetes compared with the general population. Fewer diabetes screening studies exist in the general medicine population, none of which have been based in Canada. Our primary objective in this study was to determine the prevalence of probable undiagnosed diabetes (glycated hemoglobin [A1C]≥6.5%) in hospitalized medicine patients. Secondary objectives were to identify the prevalence of undiagnosed dysglycemia (A1C≥6.0%) and the subsequent management of emergent cases. METHODS: In this prospective cohort study, adult patients admitted to internal medicine at a tertiary hospital in Ontario were screened for diabetes using an A1C test over a 3-month period. Baseline demographics and outcomes were compared using t tests, chi-square tests and Fisher's exact tests for normoglycemia, undiagnosed dysglycemia and probable undiagnosed diabetes. A regression analysis was performed to identify any relationships between various cardiovascular-related risk factors and A1C. RESULTS: A total of 53 adult patients were enrolled. The prevalence of probable undiagnosed diabetes and undiagnosed dysglycemia was 7.5% (n=4) and 30.2% (n=16), respectively. Implementation of diabetes management strategies and/or documentation of the finding occurred in 4 of 16 patients. Regression analysis showed no relationship between either cardiovascular-related risk factors or admission glucose with A1C. CONCLUSIONS: A broader screening approach may capture previously undiagnosed cases of diabetes that do not belong to traditionally at-risk populations. Future studies should focus on identifying risk factors for undiagnosed dysglycemia in hospitalized patients, including ethnicity and barriers to community access, so that appropriate screening programs can be developed.

Screening and Treatment Outcomes in Adults and Children With Type 1 Diabetes and Asymptomatic Celiac Disease: The CD-DIET Study.

OBJECTIVE: To describe celiac disease (CD) screening rates and glycemic outcomes of a gluten-free diet (GFD) in patients with type 1 diabetes who are asymptomatic for CD. RESEARCH DESIGN AND METHODS: Asymptomatic patients (8-45 years) were screened for CD. Biopsy-confirmed CD participants were randomized to GFD or gluten-containing diet (GCD) to assess changes in HbA1c and continuous glucose monitoring over 12 months. RESULTS: Adults had higher CD-seropositivity rates than children (6.8% [95% CI 4.9-8.2%, N = 1,298] vs. 4.7% [95% CI 3.4-5.9%, N = 1,089], P = 0.035) with lower rates of prior CD screening (6.9% vs. 44.2%, P < 0.0001). Fifty-one participants were randomized to a GFD (N = 27) or GCD (N = 24). No HbA1c differences were seen between the groups (+0.14%, 1.5 mmol/mol; 95% CI -0.79 to 1.08; P = 0.76), although greater postprandial glucose increases (4-h +1.5 mmol/L; 95% CI 0.4-2.7; P = 0.014) emerged with a GFD. CONCLUSIONS: CD is frequently observed in asymptomatic patients with type 1 diabetes, and clinical vigilance is warranted with initiation of a GFD.

Closing the Gap: Results of the Multicenter Canadian Randomized Controlled Trial of Structured Transition in Young Adults With Type 1 Diabetes.

OBJECTIVE: To determine if a structured transition program for young adults with type 1 diabetes improves clinic attendance, glycemic control, diabetes-related distress, quality of life, and satisfaction with care. RESEARCH DESIGN AND METHODS: In this multicenter randomized controlled trial, young adults (17-20 years) with type 1 diabetes were randomly assigned to a transition program with a transition coordinator or to standard care. The intervention lasted 18 months (6 in pediatric and 12 in adult care). The primary outcome was the proportion of participants who failed to attend at least one adult diabetes clinic visit during the 12-month follow-up after completion of the intervention. RESULTS: We randomized 205 participants, 104 to the transition program and 101 to standard care. Clinic attendance was improved in the transition program (mean [SD] number of visits 4.1 [1.1] vs. 3.6 [1.2], P = 0.002), and there was greater satisfaction with care (mean [SD] score 29.0 [2.7] vs. 27.9 [3.4], P = 0.032) and less diabetes-related distress (mean [SD] score 1.9 [0.8] vs. 2.1 [0.8], P = 0.049) reported than in standard care. There was a trend toward improvement in mean HbA1c (8.33% [68 mmol/mol] vs. 8.80% [73 mmol/mol], P = 0.057). During the 12-month follow-up, there was no difference in those failing to attend at least one clinic visit (P = 0.846), and the mean change in HbA1c did not differ between the groups (P = 0.073). At completion of follow-up, the groups did not differ with respect to satisfaction with care or diabetes-related distress and quality of life. CONCLUSIONS: Transition support during this 18-month intervention was associated with increased clinic attendance, improved satisfaction with care, and decreased diabetes-related distress, but these benefits were not sustained 12 months after completion of the intervention.

Complete anterior pituitary failure and postpartum cardiomyopathy.

OBJECTIVE: To present a case of presumed autoimmune hypophysitis that occurred concurrently with severe postpartum cardiomyopathy and pneumonitis. METHODS: We describe the clinical, laboratory, and imaging findings in a young postpartum woman who presented with decompensated heart failure. RESULTS: Two weeks after childbirth, a 37-year-old previously healthy woman required urgent pericardiocentesis and inotropic support because of new-onset left ventricular systolic dysfunction, pericardial effusions, and hypotension. Analysis of pericardial fluid was negative for malignant cells and culture, and no cardiac tamponade or thrombus was evident. Results of a rheumatologic serology survey were negative, as was an assessment for antithyroid antibodies. Chest radiography revealed bilateral pleural effusions. Magnetic resonance imaging of the pituitary showed a homogeneously enlarged gland, consistent with the postpartum state, but no discrete pituitary lesions. Laboratory results included low levels of thyrotropin, free triiodothyronine, free thyroxine, and cortisol and a high erythrocyte sedimentation rate. The patient's symptoms responded to prednisone therapy (60 mg/day) as well as an angiotensin-converting enzyme inhibitor and a b -adrenergic blocking agent. Follow-up magnetic resonance images showed an atrophic pituitary with an empty sella turcica. CONCLUSION: To our knowledge, this is the first reported case of concomitant presumed autoimmune hypophysitis, complete anterior pituitary failure, postpartum cardiomyopathy, and pneumonitis.

The Celiac Disease and Diabetes-Dietary Intervention and Evaluation Trial (CD-DIET) protocol: a randomised controlled study to evaluate treatment of asymptomatic coeliac disease in type 1 diabetes.

INTRODUCTION: Coeliac disease (CD) is an autoimmune condition characterised by gluten-induced intestinal inflammation, and observed at a 5-10 fold greater prevalence in type 1 diabetes. While universal screening for CD in patients with diabetes is frequently advocated, objective data is limited as to benefits on diabetes control, bone health or quality of life related to the adoption of a gluten-free diet (GFD) in the large proportion of patients with diabetes with asymptomatic CD. The Celiac Disease and Diabetes-Dietary Intervention and Evaluation Trial (CD-DIET) study is a multicenter, randomised controlled trial to evaluate the efficacy and safety of a GFD in patients with type 1 diabetes with asymptomatic CD. METHODS AND ANALYSIS: Children and adults (8-45 years) with type 1 diabetes will be screened for asymptomatic CD. Eligible patients with biopsy-proven CD will be randomly assigned in a 1:1 ratio to treatment with a GFD for 1 year, or continue with a gluten-containing diet. The primary outcome will evaluate the impact of the GFD on change in glycated haemoglobin. Secondary outcomes will evaluate changes in bone mineral density, blood glucose variability and health-related quality of life between GFD-treated and the regular diet group over a 1-year period. The study was initiated in 2012 and has subsequently expanded to multiple paediatric and adult centres in Ontario, Canada. ETHICS AND DISSEMINATION: The findings from this study will provide high-quality evidence as to the impact of GFD treatment on glycaemic control and complications in asymptomatic children and adults with CD and type 1 diabetes. TRIAL REGISTRATION NUMBER: NCT01566110.

Is carotid ultrasound a useful tool in assessing cardiovascular disease in individuals with diabetes?

Coronary heart disease is a major cause of morbidity and mortality in North America. Its prevention is therefore an important clinical goal. Individuals with both Type 1 and Type 2 diabetes mellitus are at increased risk of developing heart disease as compared with those without diabetes. Carotid ultrasound is now a well-validated tool to study the presence and progression of cardiovascular disease. Using ultrasound one can determine elastic properties of the vessel wall (distensibility and compliance) as well as intima-media thickness (IMT). Several large studies have shown that IMT is a useful predictor of future cardiovascular events such as myocardial infarction and stroke, and is well correlated with other traditional risk factors such as blood pressure, lipids, level of glycemic control, and smoking. For this reason, carotid ultrasound may add valuable clinical information above and beyond that provided by traditional risk factors. The use of carotid ultrasound in the pediatric and adolescent population is increasing, and one study has shown decreased distensibility in adolescents with Type 1 diabetes mellitus versus controls. However, IMT measurements in the children and teens with Type 1 diabetes have yielded conflicting results, and larger, longitudinal studies are needed in this area.

Cardiac and vascular function in adolescents and young adults with type 1 diabetes.

The objective was to prospectively define cardiac and vascular function in adolescents and young adults with type 1 diabetes over a 3-year period. Thirty-three subjects with type 1 diabetes were studied in 1998, and 28 returned for follow-up in 2001. There were 28 controls without diabetes. All subjects underwent ultrasonography of the carotid artery to determine distensibility, compliance, and intimal-medial thickness, as well as echocardiographic studies, lipid profile, and measurement of hemoglobin A1c (HbA1c) levels and urinary albumin excretion rate. The diabetes group showed no significant change over the 3-year follow-up in lipid profile, HbA1c level, or albumin excretion rate, but a significant increase in body mass index. The diabetes and control groups were similar in age, lipid profile, and albumin excretion rate. Carotid artery distensibility and compliance in the diabetes group increased significantly from baseline to follow-up but did not differ significantly from controls. The intimal-medial thickness of the diabetes group remained unchanged over time but tended to be higher than controls. Echocardiographic studies showed no difference between the diabetes and control groups, but there was a small change in left ventricular posterior diastolic wall diameter in the subjects with diabetes over the 3-year period. There was an overall improvement in carotid function and no change in cardiac measures in subjects with diabetes over the 3 years, such that cardiac and vascular function were similar to those of controls. The reason for the improvement is uncertain, but may relate to the improvement of insulin sensitivity at the end of the pubertal growth period, rather than to changes in metabolic control or lipid profiles.
