ERUPTIVE XANTHOMAS: IMPORTANCE OF RECOGNITION TO REDUCE DELAY OF EFFECTIVE TRIGLYCERIDE REDUCTION.
Eruptive xanthomas are localized lipid deposits in the dermis and an important early clue to severe hypertriglyceridemia. These small erythematous or yellow papules that localize to the extensor surfaces of extremities, buttocks, and the back are often overlooked during routine visits secondary to poor familiarity and limited skin examinations. We present 3 cases of patients with eruptive xanthomas and severe hypertriglyceridemia who underwent skin biopsy and waited weeks to years before receiving effective treatment. ⋯ Third, evaluate the Four D's of secondary hypertriglyceridemia: Diet/Lifestyle, Drugs/Medications, and Diseases/Disorders of metabolism. Finally, initiate effective treatment promptly after recognition. This includes beginning with a minimal fat diet and appropriate pharmacological intervention to control triglycerides as outlined in recent guidelines.

Transthyretin amyloidosis (ATTR) is an under-recognized cause of cardiomyopathy and neuropathy. Until recently, there were limited therapeutic options for ATTR. However, new therapeutics, including tafamidis, patisiran, and inotersen, increase both quality and length of life in patients with ATTR. ⋯ In addition, we discuss emerging ATTR therapies including improvements in drug delivery methods, antibodies to break down deposited amyloid fibrils, and gene editing. ATTR is a prime example of how an understanding of the pathophysiological basis of disease can lead to effective therapies. The future of ATTR therapy is bright, with every reason to believe outcomes will continue to improve.

Update on the Contemporary Treatment of Light Chain Amyloidosis Including Stem Cell Transplantation.
The management of immunoglobulin light chain (AL) amyloidosis is complex. Emerging data have shown promising results for several novel agents. We review the management of AL amyloidosis, including factors that determine transplant eligibility, treatment options for transplant-ineligible patients, and treatment options for relapsed/refractory AL amyloidosis. ⋯ The latter option is based on a landmark trial that led to the first US Food and Drug Administration-approved therapy for AL amyloidosis. For relapsed/refractory disease, novel therapeutics including proteosome inhibitors, immunomodulatory agents, and monoclonal antibodies have shown promising results. In this review, we summarize data for various therapeutics in different clinical scenarios of AL amyloidosis.

The use of statin therapy in atherosclerotic cardiovascular disease (ASCVD) has demonstrated substantial improvement in morbidity and mortality of the aging population. Despite exhaustive studies demonstrating the benefits of statin therapy linking lower cholesterol levels to decreased vascular events, statin guidelines vary greatly with age, and recommendations are unclear regarding initiation and discontinuation of statin therapy in patients 65 years and older. ⋯ Therefore, patients who meet these criteria, regardless of age, should begin statin therapy. There is also some evidence to suggest that statin therapy may be beneficial in primary prevention of major cardiovascular events, although these data are not as well studied as secondary prevention use of statin therapy, and should therefore be individualized for each patient.

Cervical myelopathy is a clinical syndrome caused by compression of the spinal cord between the levels of the C1 and T1 vertebrae. Its clinical presentation can mimic other degenerative and neurological pathologies, making diagnosis challenging. ⋯ Treatment options are focused on decompression of the spinal canal from an anterior, posterior, or combined anterior and posterior surgical approach depending on the location of compression and patient factors. Outcomes are favorable if treatment is performed prior to severe symptom onset.
