A Case Report of Cytarabine-Induced Red Ear Syndrome.

Cytarabine is an antimetabolite used in the treatment of acute myeloid leukemia which acts by inhibiting DNA synthesis and subsequently cell division. It works on rapidly dividing cells, for that reason, it affects cancer cells, bone marrow and skin cells. Cytarabine has variable cutaneous side effects, the most common one is palmar-plantar erythema which usually presents with a tingling sensation around 5-7 days after cytarabine initiation, followed by erythema and tenderness. Auricular erythema is a rare subtype involving bilateral ears which often presents as ear redness and tenderness as described in the presented case. It is unclear if the skin side effects are related to cytarabine dose or plasma concentration. Most cases of auricular erythema have a benign course and resolve spontaneously. Treatment is mainly conservative. Steroids and antihistamines can be used to speed up recovery given that the pathophysiology is thought to be immediate or due to a delayed hypersensitivity reaction to cytarabine.

Tejocote Root's Role in Symptomatic Mobitz Type 1 Heart Block: A Compelling Case Report.

The clinical presentation and diagnosis of Tejocote root toxicity causing Mobitz Type 1 remains a scarcely clinical phenomenon, often resulting in delayed diagnosis and treatment. This case report highlights a 30-year-old female presenting with a constellation of symptoms, including fatigue, dizziness, chest pressure, myalgias, nausea, vomiting, and peripheral tingling. Significantly, the patient had been using Tejocote root as an over-the-counter laxative acquired from Mexico. Laboratory findings revealed detectable Digoxin levels in her bloodstream, while an electrocardiogram (EKG) indicated sinus bradycardia with Mobitz Type 1 heart block. The patient was treated with a single dose of atropine 0.5 mg IV push. A repeat EKG before discharge showed resolution of the Mobitz type 1. This case underscores the potential cardiovascular repercussions of Tejocote root consumption and emphasizes the importance of heightened clinical awareness, especially in regions where such herbal supplement usage is prevalent.

Prevalence and clinical significance of deep vein thrombosis in Hispanic patients with acute pulmonary embolism.

The prevalence of concomitant deep vein thrombosis (DVT) and its impact on 30-day outcomes in Hispanic patients with acute pulmonary embolism (PE) is unknown. We retrospectively studied a cohort of Hispanic patients admitted for acute PE to determine the relationship of concomitant DVT to clot burden on chest computer tomography (CT), right heart strain, and 30-day mortality. We identified 391 patients admitted with acute PE; 168 (42.9%) had concomitant DVTs on admission; 39 patients (9.9%) died during the 30-day follow-up: 12 patients without concomitant DVT and 27 with concomitant DVT, respectively (p < .001). The presence of a proximal DVT independently predicted 30-day mortality even after adjusting for age, gender and admission PE severity index scores (PESI) (hazard ratio [HR] 2.0; 95% confidence interval [CI]: 1.4-3.0, p = .001). Proximal DVTs remained a significant predictor of 30-day mortality in patients with low and intermediate PESI scores (HR 2.5; 95% CI: 1.1-6.0, p = .035). The prevalence of concomitant DVT in Hispanic patients presenting with acute DVT is relatively lower than other ethnic groups. However, a proximal location of a DVT is of significant prognostic relevance. Hispanic patients with acute PE should routinely undergo compression doppler ultrasonography (CDUS) of the lower extremities.

An Unusual Case of Combined Thrombosis and Amegakaryocytopenia Resembling Thrombosis With Thrombocytopenia Syndrome Following COVID-19 Infection in an Unvaccinated Patient.

As a global community, we have learned that the manifestations of severe acute respiratory syndrome coronavirus 2 (SAR-CoV-2), infection, or coronavirus disease 2019 (COVID-19), extends far beyond respiratory compromise. Thrombocytopenia is thought to occur secondary to increased platelet consumption. Platelet activation and platelet-mediated immune inflammation contribute towards the thromboembolic complications seen in COVID-19 patients. In this report, the authors present the unusual case of a 75-year-old female with a history of COVID-19 infection who presented with a transient ischemic attack, thrombocytopenia, and amegakaryocytopenia.

High-Intensity Statin With Severe Consequences: A Case of Non-autoimmune Rosuvastatin-Induced Myonecrosis.

Statins constitute a cornerstone in the primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD). The routine use of these lipid-lowering agents may lead to unintentional neglect of their well-known myotoxic properties. We report the case of a 77-year-old female with a two-year history of rosuvastatin use who presented with progressive bilateral upper and lower extremity muscular weakness for one week, which improved upon discontinuation of her long-term statin therapy. The authors aim to draw attention to this potentially underdiagnosed cause of disability. It is imperative that clinicians are able to appreciate the myopathic spectrum of statin therapy, irrespective of the duration of use. Myonecrosis, in particular, can progress to rhabdomyolysis, leading to irreversible renal dysfunction, electrolyte abnormalities, and subsequent cardiac dysrhythmias. Ultimately, statin-induced myopathy may significantly hinder activities of daily living and impair quality of life. It is, however, a reversible condition if diagnosed and appropriately managed early on. Clinicians are encouraged to acquaint themselves with the symptomatology and relevant laboratory values that commonly accompany this acute condition.

A Case Report on Rare Presentation of Sporadic Disease: Dermatomyositis Sine Dermatitis-Diagnosis and Management.

Dermatomyositis sine dermatitis (DMSD) is one of the rare idiopathic inflammatory myopathies. Based on predominant symptoms faced by patients, it is classified into 3 types: (1) classic dermatomyositis (DM), where patients have both muscle and skin symptoms; and (2) amyopathic DM, when only skin symptoms present with no muscle involvement. Whereas (3) DMSD has mainly muscle symptoms with muscle antibodies but no skin rashes. There have been only nearly 10 published articles about DMSD proving this disease's scarcity. At the same time, it shows the importance of discussing the unusual presentation of such a rare disease. Here we present, a 28-year-old woman with worsening proximal muscle weakness. The decreased muscle strength on physical examination and elevated creatinine kinase required more work up for autoimmune disease. Interestingly, on muscle biopsy, anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody returned positive, and the patient responded well to 3 days course of steroids. The lack of skin involvement, the predominance of muscle symptoms, and positive anti-MDA5 antibody indispensably diagnosed patients with DMSD. The previously published articles have proved the association between anti-NXP-2 antibody and DMSD, which was not seen in our case. The systemic involvement of DMSD can lead to interstitial lung disease, where due to diffuse alveolar damage and pulmonary fibrosis, patients end up requiring intubation and may be associated with higher-level mortality. In our case, chest X-rays and computed tomography (CT) scans were unremarkable for lung involvement, so as no paraneoplastic syndromes were present, which has also been reported in DMSD patients previously.
