A Rare and Lethal Complication: Cerebral Edema in the Adult Patient with Diabetic Ketoacidosis

Etiology of Drug-Induced Edema: A Review of Dihydropyridine, Thiazolidinedione, and Other Medications Causing Edema

Edema is an accumulation of fluid in the body's tissues that affects millions of Americans yearly. It can affect multiple body parts, for example, the brain or eyes, but often occurs in the periphery, including the feet and legs. Medications, such as dihydropyridine and thiazolidinediones (TZDs), can be the etiology of edema. Edema can develop in association with problems in the vasculature or lymphatic flow. In recent years, a better understanding of these drug-induced mechanisms has been appreciated. Specifically, dihydropyridines can increase hydrostatic pressure and cause selective pre-capillary vessel vasodilation. TZDs can cause edema through increased vascular permeability and increased hydrostatic pressure. Specifically, peroxisome proliferator-activated receptor gamma (PPARγ) stimulation increases vascular endothelial permeability, vascular endothelial growth factor (VEGF) secretion, renal sodium, and fluid retention. Other drugs that can cause edema include neuropathic pain agents, dopamine agonists, antipsychotics, nitrates, nonsteroidal anti-inflammatory (NSAIDS), steroids, angiotensin-converting enzyme (ACE) inhibitors, and insulin. There are various clinical presentations of edema. Since multiple mechanisms can induce edema, it is important to understand the basic mechanisms and pathophysiology of drug-induced edema. Edema can even become fatal. For example, angioedema can occur from ACE inhibitor therapy. In this regard, it is considered a medical emergency when there is laryngeal involvement. This review aims to thoroughly appreciate the multiple causes of drug-induced edema and the ways it can be treated or prevented.

Testing proximal, intermediate, and health outcomes of patient centered communication among non-pregnant women of childbearing age with diabetes mellitus: Findings from the Medical Expenditure Panel Survey 2012-2018

Objective

To determine associations between patient-centered communication (PCC) and overall healthcare ratings, self-efficacy, and management adherence among reproductive-age women with diabetes within the framework of Epstein and Street's conceptual model.

Methods

We analyzed longitudinal data from the 2012-2018 Medical Expenditure Panel Survey. The sample included 493 non-pregnant women of childbearing age (18-45 years) with diabetes. Independent variables were domains of PCC (listening, explaining, respecting, spending time, giving instructions, among others). Dependent variables were overall healthcare ratings, self-efficacy, and management adherence. Crude and adjusted associations were evaluated.

Results

Non-pregnant women of childbearing age who reported that their provider always listened to them, explained things, showed respect, and spent enough time with them had greater odds of reporting high overall healthcare ratings. Those who reported their provider always listened to them and spent enough time with them had greater odds of reporting better diabetes care adherence than those whose health care providers did not.

Conclusion

Findings demonstrate that non-pregnant women of childbearing age who report having optimal PCC are more likely to adhere to their diabetes care regimen.

Innovation

This is the first known study using a nationally representative sample of non-pregnant women of childbearing age to examine multiple layers of PCC.

Diabetic ketoacidosis (DKA) induced cerebral edema complicating small chronic subdural hematoma/hygroma/ at Zewuditu memorial hospital: a case report

BACKGROUND

While both DKA & CSDH/subdural hygroma/ are known to cause significant morbidity and mortality, there is no a study that shows the role & effect of DKA on CSDH/subdural hygroma/ & vice versa to authors' best knowledge; hence this work will show how important relation does exist between DKA & CSDH/ hygroma. This study highlights the diagnostic & management challenges seen for a case of a 44 years old female black Ethiopian woman admitted with a diagnosis of newly diagnosed type 1 DM with DKA + small CSDH/subdural hygroma/ after she presented with sever global headache and a 3 month history of lost to her work. She needed burrhole & evacuation for complete clinical improvement besides DKA's medical treatment.

CONCLUSION

DKA induced cerebral edema on the CSDH/subdural hematoma/ can have a role in altering any of the parameters (except the thickness of CSDH) for surgical indication of patients with a diagnosis of both CSDH +DM with DKA. Hence, the treating physicians should be vigilant of different parameters that suggests tight brain &/ cerebral edema (including midline shift, the status of cisterns, fissures & sulci) and should not be deceived of the thickness of the CSDH/subdural hygroma/alone; especially when there is a disproportionately tight brain for the degree of collection. Whether DKA induced cerebral edema causes a subdural hygroma is unknown and needs further study.

Fatal Cerebral Edema in a Young Adult with Diabetic Ketoacidosis: Blame the Bicarbonate?

Cerebral edema is a devastating complication of DKA which is extremely rare in adults but is the leading cause of diabetes-related death in the pediatric population. Newly diagnosed diabetes, younger age, first episode of DKA, severity of DKA at presentation, and administration of bicarbonate are predictive of cerebral edema in DKA. We present a case of a young adult with DKA as the presenting symptom of diabetes, whose clinical course was complicated by renal failure, refractory shock, and cerebral edema. This case addresses the controversy surrounding bicarbonate therapy in DKA and its possible role in the development of a rare fatal complication of DKA.

Diabetic ketoacidosis

Diabetic ketoacidosis (DKA) is the most common acute hyperglycaemic emergency in people with diabetes mellitus. A diagnosis of DKA is confirmed when all of the three criteria are present - 'D', either elevated blood glucose levels or a family history of diabetes mellitus; 'K', the presence of high urinary or blood ketoacids; and 'A', a high anion gap metabolic acidosis. Early diagnosis and management are paramount to improve patient outcomes. The mainstays of treatment include restoration of circulating volume, insulin therapy, electrolyte replacement and treatment of any underlying precipitating event. Without optimal treatment, DKA remains a condition with appreciable, although largely preventable, morbidity and mortality. In this Primer, we discuss the epidemiology, pathogenesis, risk factors and diagnosis of DKA and provide practical recommendations for the management of DKA in adults and children.
