Anomalous Right Coronary Artery From Pulmonary Artery Presenting as Inferior Wall Ischemia: A Case Report.

We illustrate the case of a 62-year-old man with a symptomatic anomalous right coronary artery from pulmonary artery (ARCAPA). Our patient had presented with dyspnea on exertion with electrocardiogram showing pronounced inferior Q waves and marked inferolateral ST-T wave changes. The patient had a nuclear stress test which showed inferior wall ischemia. Subsequently, the patient underwent coronary angiography which showed an ARCAPA. The patient underwent surgical repair with reimplantation of the right coronary artery to the ascending aorta which was tolerated well. Our case illustrates ARCAPA presenting late in adulthood with ischemic symptoms that was treated with corrective surgery.

Ongoing and future clinical trials of device therapies for patients with heart failure.

Heart failure continues to pose a significant burden in terms of morbidity, mortality, and healthcare costs worldwide despite the implementation of guideline-directed medical therapy. Addressing this challenge and improving clinical outcomes for this patient population remains an urgent priority. Recognizing the limitations in current medical approaches and exploring strategies to overcome these limitations are crucial steps toward improving future outcomes. Various device-based interventions, such as Cardiac Resynchronization Therapy devices and Left Ventricular Assist Devices, have demonstrated notable benefits for individuals with heart failure. Our review is aimed at summarizing the ongoing research into new device therapies for heart failure, emphasizing their potential to overcome the current challenges in treatment. By utilizing Clinicaltrials.gov, an online repository, we conducted a comprehensive search for trials investigating emerging device therapies for patients dealing with heart failure.

BRASH Syndrome: A Systematic Review of Reported Cases.

The pathophysiology of Bradycardia-Renal Failure-Atrioventricular Nodal Blockade-Shock-Hyperkalemia (BRASH) syndrome involves acute renal injury leading to ineffective clearance of AV nodal agents and potassium. Theoretically, the synergy between AV nodal blockade and hyperkalemic cardiac dysconduction results in circulatory collapse at less-than-expected doses of both. Our study aims to characterize the presentation of BRASH and provide clinical evidence of its risk factors. This systematic review comprises all reported cases of BRASH until February 2022. The average age and Charleston Comorbidity Index at presentation was 69 years and 3.8 respectively - hypertension (71%) was most prevalent followed by diabetes mellitus (48%) and chronic kidney disease (44%). The most frequent presenting complaint was fatigue or syncope (49%). More than half of all patients presented with nonsevere hyperkalemia (less than 6.5 mmol/L) and the mean serum creatinine was 3.6 mg/dL. Beta-blockers (75%) were the most commonly implicated nodal agents. Presenting mean arterial pressure was 62 mm Hg and heart rate averaged 36 bpm; junctional escape rhythm (50%), sinus bradycardia (17.1%), and complete heart block (12.9%) were generally observed on EKG. While most patients responded to medical management, 20% of patients required renal replacement therapy and 33% required transvenous or transcutaneous pacing. No patients underwent permanent pacemaker placement and the in-hospital mortality of BRASH was 5.7%. The diagnosis of BRASH requires a high index of suspicion; its synergistic pathology results in a dramatic clinical presentation that can be easily overlooked. As hypothesized, the degree of renal failure and hyperkalemia are not congruent with the presenting circulatory shock. The significant mortality of this syndrome presents an opportunity for intervention with timely recognition.

A rare case of post-transplant lymphoproliferative disorder (Hodgkins lymphoma) post autologous stem cell transplantation: A case report and review of literature.

Introduction: Post-transplant lymphoproliferative disorders(PTLD) include a mix of rare yet life endangering complications. Case presentation and conclusion: Here, we report a case of a 63-year-old man who was the victim of post-transplant lymphoproliferative disorder (Hodgkin's lymphoma). The patient was initially diagnosed with multiple myeloma, for which chemotherapy and the autologous stem cell transplant was carried out. Post transplant patient was stable but on a follow up visit 6 months after the transplant he presented with generalized lymphadenopathy.His subsequent workup was done including a biopsy of cervical lymph node, which revealed Classical Hodgkin's lymphoma (post-transplant lymphoproliferative disorder (PTLD)) of mixed cellularity type.The patient was started on chemotherapy and received a total of 4 cycles of Chemotherapy (ABVD) before his condition started deteriorating as chemotherapy was poorly tolerated leading to Bleomycin toxicity. The patient regrettably passed away due to an NSTEMI.

Thyroid storm secondary to acute Streptococcus pyogenes pharyngitis.

Thyroid storm is an endocrine emergency associated with high mortality rates, especially in hospitalized populations. Infection serves as an exceedingly common trigger for the development of thyrotoxicosis. We present a rare case of a 24-year-old woman who developed acute thyrotoxicosis secondary to group A Streptococcus throat infection. The patient received a combination of thionamides, antibiotics, glucocorticoid, beta-blocker, and iodine preparation that resulted in the resolution of her symptoms.

COVID-19 Vaccine and Long COVID: A Scoping Review.

As the COVID-19 pandemic progresses, changing definitions and therapeutics regarding the post-acute sequela of COVID-19, particularly long COVID, have become a subject of great interest and study. The study aims to describe the pathophysiology and discuss different therapeutic agents currently available for long COVID. Another objective is to assess comparative efficacy between different types of vaccines on symptoms of long COVID. A preliminary search was conducted using Ovid Medline, Embase, medRxiv, and NIH COVID-19 portfolios. A total of 16 studies were included in our review. Despite some of the data showing variable results, most of the vaccinated patients reported improvement in long COVID symptoms with no significant difference between various types of vaccines. Further trials are needed to better identify the comparative efficacy of vaccines for long COVID and ascertain other therapeutic modalities.

A blistering new era for bullous pemphigoid: A scoping review of current therapies, ongoing clinical trials, and future directions.

Bullous pemphigoid (BP) is a severe autoimmune blistering skin disorder that primarily causes disease in the older population and is the most prevalent subepidermal variant of the pemphigoid diseases. It manifests as exquisitely pruritic vesiculobullous eruptions and is associated with significant morbidity and mortality. Studies are reporting an increase in prevalence, and, among the elderly, BP is no longer considered to be as rare as previously thought. The pathogenesis involves autoantibodies directed against proteinaceous components of hemidesmosomes, with consequent autoimmune destruction of the dermal-epidermal junction. In recent times, more complex elements of the underlying inflammatory orchestra have been elucidated and are being used to develop targeted immunotherapies. The primary treatment modalities of BP include the use of topical and systemic corticosteroids, certain non-immunosuppressive agents (tetracyclines, nicotinamide, and sulfone), and immunosuppressants (methotrexate, azathioprine, cyclophosphamide, and Mycophenolate). However, in the long term, most of these agents are associated with substantial toxicities while recurrence rates remain high. Such egregious prospects led to significant efforts being directed towards developing newer targeted therapies which work by attenuating specific newly discovered pillars of the inflammatory pathway, and these efforts have garnered hope in providing safer alternatives. Our review focuses on presenting the various therapeutic options that are currently in trial since December 2019, as well as on summarizing presently established treatment guidelines to provide readers with the latest exciting updates.

Fungal burn wound infection caused by Fusarium dimerum: A case series on a rare etiology.

INTRODUCTION: Fusarium dimerum is a filamentous mold associated with poor outcomes in immunocompromised hosts and burn victims. It can be acquired via inhalation or through skin dehiscence. METHODS: Our work presents a Case series of 8 patients from ages 3-57 years who were admitted with multiple burn wounds over the past 6 months. After initial stabilization measures, they all underwent debridement for the lesions after negative initial fungal cultures. The 44-year-old male was the first patient to develop punched-out eruptions on burn areas 7 days after admission; all the other patients experienced similar lesions during the next 6 days. Tissue cultures of the lesions exhibited Fusarium dimerum growth. The patients were managed accordingly with amphotericin B or voriconazoles. All the patients recovered except the 11-year-old boy, who expired on day 9 due to ARDS and sepsis complications. OUTCOMES: Infection with Fusarium dimerum carries a high risk of dissemination in burn infections. Hence, appropriate screening should be carried out via histologic and mycologic diagnostics early in the disease course. CONCLUSION: Considering the sparse literature that is available regarding Fusarium infection in burn victims, this study aims to improve the knowledge surrounding different facets of this disease including its epidemiology, diagnosis, management, and the need to maintain high suspicion of this fungal disease in burn patients.
