Immune checkpoint inhibitor-induced myasthenia gravis, myocarditis, and myositis: A case report.

Key Clinical Message: Immune checkpoint inhibitors can rarely lead to occurrence of myositis, myocarditis, and myasthenia gravis (MG). Early recognition and multidisciplinary management are crucial for optimal outcomes. Vigilance for overlapping toxicities is essential in patients receiving combination immunotherapy. Abstract: The use of immune checkpoint inhibitors (ICIs) has revolutionized cancer treatment, but it is associated with immune-related adverse events (IRAEs) affecting various organ systems. The simultaneous occurrence of MG, myocarditis, and myositis highlights the complex nature of IRAEs. Early recognition and comprehensive multidisciplinary management are crucial for optimal patient outcomes. We present a unique case report of a 76-year-old male patient with advanced melanoma who developed concurrent myositis, myocarditis, and MG while receiving combination immunotherapy with Nivolumab and Ipilimumab. This case underscores the significance of recognizing and addressing the "Terrible Triad" of IRAEs in patients receiving ICIs. Healthcare providers should maintain a high index of suspicion for overlapping toxicities and promptly initiate appropriate interventions.

Anxiety and its risk factors among non-Japanese residents living in Japan undergoing COVID-19 situation: A cross-sectional survey.

INTRODUCTION: In the context of collective efforts taken in Japan to control the spread of COVID-19, the state of emergency and social distancing have caused a negative impact on the mental health of all residents, including foreign communities in Japan. This study aimed to evaluate the level of anxiety and its associated factors among non-Japanese residents residing in Japan during the COVID-19 pandemic. METHODS: A web-based survey in 13 languages was conducted among non-Japanese residents living in Japan during the COVID-19 situation. The State-Trait Anxiety Inventory assessed the level of anxiety-State (STAI-S) scores prorated from its six-item version. The multivariable logistic regression using the Akaike Information Criterion (AIC) method was performed to identify the associated factors of anxiety among participants. RESULTS: From January to March 2021, we collected 392 responses. A total of 357 valid responses were analyzed. 54.6% of participants suffered from clinically significant anxiety (CSA). In multivariable logistic model analysis, the CSA status or the high level of anxiety was associated with three factors, including having troubles/difficulties in learning or working, decreased sleep duration, and decreased overall physical health (p<0.05). CONCLUSION: Our study suggests several possible risk factors of anxiety among non-Japanese residents living in Japan undergoing the COVID-19 pandemic, including the troubles or difficulties in learning or working, the decrease in sleep duration, and the decrease in overall physical health.

Unveiling Complexity: A Case Report of Catastrophic Antiphospholipid Syndrome With Coronary Occlusion and a Concomitant Patent Foramen Ovale Shunt.

Antiphospholipid syndrome (APLS) and systemic lupus erythematosus (SLE) are rare autoimmune disorders that afflict a small percentage of the global female population. The complexity of these conditions is further exacerbated by their propensity to give rise to recurrent thrombosis and obstetric morbidity, thereby posing intricate challenges for clinicians and patients alike. One of the most concerning aspects of these diseases is the heightened risk they confer for accelerated atherosclerosis, which can ultimately culminate in the development of acute coronary syndrome (ACS). This case report describes a 27-year-old female with APLS, SLE, and lupus nephritis. She suffered from a catastrophic antiphospholipid syndrome (CAPS) episode and simultaneously developed ACS. She also had a patent foramen ovale (PFO) shunt.

Atrial Fibrillation Ablation in Patients With Chronic Kidney Disease: A Review of Literature.

Atrial fibrillation (AF) is a common arrhythmia among patients with chronic kidney disease (CKD), which leads to increased cardiovascular complications. Catheter ablation (CA) has emerged as an effective and safe treatment for AF in CKD patients. CA offers tailored treatment strategies and presents a safer alternative with fewer adverse outcomes than anti-arrhythmic agents. Although CKD patients undergoing ablation have similar complication rates to non-CKD patients, they face a higher risk of hospitalization due to heart failure. Furthermore, CA shows promise in improving kidney function, particularly in individuals who maintain sinus rhythm. Future research should address limitations by including advanced CKD patients, conducting longer-term follow-ups, and developing individualized treatment approaches.

Outcome of Atrial Fibrillation Ablation in Cancer Patients: A Review.

Atrial fibrillation (AF), a cardiac arrhythmia, exhibits a heightened prevalence among individuals diagnosed with cancer, notably prominent in cases of lung and gastrointestinal malignancies. Robust evidence from extensive studies underscores this association, emphasizing its clinical significance. However, the precise mechanistic underpinnings and specific risk factors linking cancer and AF remain a subject of incomplete understanding. Notably, the prevalence of AF in cancer patients substantially exceeds that in non-cancer counterparts, prompting further exploration of the underlying pathophysiological processes. This review aims to address the existing knowledge void regarding AF management in cancer patients, with a specific focus on the potential role of ablation procedures. While catheter and surgical ablation techniques have been thoroughly investigated and validated as effective treatments within non-cancer populations, their applicability and outcomes in cancer patients have remained inadequately explored. The principal objective of this exhaustive review is to bridge this research gap by conducting a meticulous examination of the feasibility, safety, and effectiveness of ablation interventions for AF in the context of cancer patients. By amalgamating existing evidence and pinpointing critical areas necessitating additional investigation, this review endeavors to provide invaluable insights into AF management in cancer patients, with the ultimate goal of enhancing their clinical care and optimizing outcomes.

Granulomatosis with polyangiitis mimicking COVID-19 pneumonia: A case report.

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a necrotizing vasculitis characterized by small-to-medium-sized vessel involvement and the presence of antineutrophil cytoplasmic antibodies (ANCA). We present a case of a 26-year-old Asian woman who was transferred to our center from a nearby hospital, where she presented with shortness of breath, tested positive for COVID-19, and was being managed for COVID-19 pneumonia. She also had hemoptysis, skin lesions, and left foot numbness. Serological markers and VATS-guided lung biopsy confirmed the diagnosis. Treatment with methylprednisolone and rituximab led to stabilization, despite complications of subcutaneous emphysema and lower extremity neuropathic symptoms. Early recognition and appropriate management of GPA are crucial for optimal outcomes.

Reverse takotsubo syndrome heralding as ventricular fibrillation: a case report.

Reverse takotsubo syndrome, a variant of takotsubo cardiomyopathy, is an acute left ventricular failure characterized by the basal akinesis/hypokinesis associated with apical hyperkinesis. Its presentation is similar to that of the acute coronary syndrome. Case presentation: The authors present a case of a 49-year-old woman, a vice principal at a local school with a history of hypertension, who was brought to our center after she collapsed while giving a graduation speech. Reverse takotsubo was a presumed diagnosis after we ruled out other differentials. Clinical discussion: The pathophysiology of reverse takotsubo syndrome is poorly understood. It might be due to a different pattern of catecholamine-mediated myocardial dysfunction than classic takotsubo cardiomyopathy. It is often associated with physical and/or emotional stressors. Conclusion: Supportive treatment and identification and prevention of triggers can reduce the recurrence of reverse takotsubo cardiomyopathy. Physicians should be aware of various triggers for this condition.

Infective endocarditis presenting as meningitis: a case report.

Infective endocarditis (IE) primarily affects the endocardium of heart valves. Neurologic manifestations include strokes, intracerebral hemorrhages, meningitis, cerebral and spinal abscess, and mycotic aneurysms. Although rare, meningitis is a potentially life-threatening complication of IE, so physicians should be aware of this rare and fatal complication of IE. Case presentation: Here, the authors present a case of a 53-year-old male who presented with bacterial meningitis secondary to IE. His blood culture was positive for methicillin-sensitive staphylococcal aureus. Echocardiography findings were suggestive of endocarditis. Despite aggressive intensive care management, our patient did not survive. Clinical discussion: The isolation of Staphylococcus aureus in culture should raise a suspicion of foci being elsewhere outside the central nervous system. Treatment of complications like meningitis may require intrathecal antibiotics. The vegetation and neurological complications are often difficult to treat and require the participation of a multidisciplinary team. Conclusions: The diagnosis of IE in patients presenting with neurologic deficits and fever should be considered. A physician should raise a suspicion of infective foci being elsewhere outside the central nervous system if the organism isolated in culture is Staphylococcus aureus.

Use of midodrine in heart failure: a review.

Heart failure is a global health concern, affecting millions of individuals worldwide. Midodrine, an alpha-1 receptor agonist, might be a potential treatment option for patients with heart failure and concurrent hypotension. This review provides a comprehensive summary of the existing literature on the use of midodrine in heart failure patients, focusing on its pharmacology, epidemiology, and public health impact. Guideline-directed medical therapy (GDMT) is essential in heart failure management, but hypotension may limit its initiation or up-titration. Studies have shown that midodrine can improve blood pressure, reduce the need for vasopressor support, and enable the prescription of GDMT in patients who are intolerant to it due to hypotension. However, there are concerns over increased all-cause mortality in some studies, small sample sizes, and nonrandomized study designs in others. Further research, including large-scale randomized controlled trials and long-term follow-up studies, is needed to better understand the risks and benefits of midodrine use in heart failure patients, particularly in relation to GDMT. Clinicians should consider the potential advantages of midodrine against the limited evidence and potential risks before incorporating it into their clinical practice for heart failure treatment.

A Case of Thyrotoxic Periodic Paralysis: "I Can't Move!"

Thyrotoxic periodic paralysis (TPP) is a form of hypokalemic periodic paralysis associated with hyperthyroidism. It is characterized by hypokalemia associated with acute proximal symmetrical lower limb weakness and can progress to involve all four limbs and the respiratory musculature. We present a case of a 27-year-old Asian male with recurrent attacks of weakness in all four extremities. A subsequent diagnosis of thyrotoxic periodic paralysis was made, which was secondary to a previously undiagnosed Grave's disease. TPP should be a differential in a young male of Asian ethnicity who presents to the hospital with acute onset of paralysis.

A Case of Brugada Syndrome Masquerading as Acute Coronary Syndrome in a Hispanic Male.

Brugada syndrome is an aberrant ST-segment elevation in the right precordial leads. It can progress into sudden cardiac death (SCD) among patients with structurally normal hearts. Most patients are asymptomatic at presentation, but those who develop symptoms can present with syncope due to other arrhythmias such as ventricular tachycardia or fibrillation. Early diagnosis and appropriate management can prevent future complications in patients with a significant family history.

Indomethacin-Induced Hypertensive Crisis.

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed drugs to treat pain, and are easily available over the counter in lower dosages. NSAID use is associated with various side effects and elevated blood pressure is one of them. NSAIDs vary considerably in their effect on blood pressure with indomethacin being one of the NSAIDs associated with a significant increase in blood pressure. We present a case of a 58-year-old woman who developed a hypertensive crisis after a single dose of prescription indomethacin.

Soluble Guanylate Cyclase Stimulators in Heart Failure.

Heart failure has a high global burden of morbidity and mortality. Despite significant advances in medical management of heart failure, the prognosis remains poor. This justifies the search for newer therapeutic agents. Recently, soluble guanylate stimulators have demonstrated favorable results in clinical trials. This article aims to summarize the guanylate cyclase signaling pathway, the role of soluble guanylate cyclase stimulators in heart failure, and data from recent clinical trials of these drugs. We concluded that soluble guanylate cyclase stimulators have significant benefits in reducing hospitalizations in patients with heart failure with reduced ejection fraction that are at high risk of cardiovascular events. There appears to be no benefit of these drugs in patients with heart failure with preserved ejection fraction.
