A Workout to Remember: CrossFit-Induced Vertebral Artery Dissection.

Vertebral artery dissection (VAD) is a cause of brain stem stroke in the younger population and is commonly associated with trauma, sudden neck movement, or chiropractic manipulations. In this case, a 28-year-old male with a non-significant past medical history who recently started a CrossFit boot camp presented to the emergency department with right-sided neck pain, dysarthria, mild right gaze paresis, right dysmetria, and right facial droop with symptoms of Horner's syndrome. Imaging results revealed an age-indeterminate left lateral cerebellar infarct with right VAD. The goal of management is to prevent stroke, which is done with anticoagulation and potentially thrombolytic therapy if there are no contraindications. The patient received thrombolytic therapy and was treated with conservative management. The prognosis is good for patients who survive the initial dissection and are treated in this manner. It is important to obtain a thorough history of young and healthy patients who present with concerning neurologic symptoms so that precipitating activities are not missed.

Primary Peritoneal Carcinoma: A Rare Malignancy Presenting a Diagnostic Challenge.

With the advancement in technologies and the development of a vast variety of tests, diagnosing diseases has become relatively easy. However, certain diseases are challenging to diagnose due to their similarities with other disease processes. Primary peritoneal carcinoma (PPC) is one of the infrequent tumors that has a resemblance to an ovarian tumor, often making it hard to diagnose. The symptoms are non-specific, and by the time primary peritoneal cancer is diagnosed, the patient is usually at an advanced stage. Although diagnosis might be suspected based on presenting symptoms, it is rarely confirmed with symptomatology alone, requiring additional tumor markers or radiological studies. Sometimes it is diagnosed after surgical removal of the lesion. Several similarities have been described between PPC and ovarian cancer, with some studies explaining the differences as well. We highlight the importance of careful interpretation of imaging studies for the timely diagnosis of PPC. However, several factors can interfere with the analysis of test results leading to delays in diagnosis and management. Interpretation of imaging becomes difficult, especially in patients with significant ascites.

Halotherapy for Chronic Respiratory Disorders: From the Cave to the Clinical.

CONTEXT: Halotherapy (HT) is a form of speleotherapy, a respiratory therapy involving breathing inside a cave, and its therapeutic environment is similar to that of a natural salt cave. Natural crystallized salt is inhaled via aerosols or from the environment directly to enhance breathing and respiratory health-related quality of life (HRQoL). Clinicians need to be aware of its potential benefits, with relatively few or no adverse effects and consider its use an adjuvant therapy for standard care. OBJECTIVE: The current review intended to compile the existing literature on HT's use in various chronic respiratory diseases. It examines the use of dry salt inhalers; the use of saline nebulizer therapy is already well established in the literature. DESIGN: The research team performed a literature review to identify all articles published in the English language between January 1980 and December 2018 that used HT or heliotherapy and speleotherapy in the title. Pseudonyms such as salt cave therapy and salt mine therapy were also included. The source of data was the National Library of Medicine's MEDLINE/PubMed. SETTING: Literature search took primarily from the main campus of Brookdale University Hospital Medical Center and the Touro College of Osteopathic Medicine. RESULTS: Literature search and review yielded a total of 13 manuscripts that were completely assessed and incorporated into this review. Overwhelmingly studies comparing various methods of halotherapy showed improvement in various pulmonary function measures including forced expiratory volume in one second, forced vital capacity and peak expiratory flow. Other measures were also seen to improve such as HRQoL as assessed by questionnaires. CONCLUSIONS: HT has been found to have a positive effect on patients suffering from chronic respiratory diseases, improving mucociliary elimination and lung function in common chronic respiratory diseases and also HRQoL. Currently, no official guidelines exist on the use of HT in the form of salt rooms (halo chambers) or dry powder inhalers, but evidence exists for its use as a possible adjuvant therapy. More structured research in the form of randomized clinical trials is required.

Subacute Stent Thrombosis in a Patient With COVID-19 Despite Adherence to Antiplatelets.

The coronavirus disease 2019 (COVID-19) creates a significant burden on the cardiovascular system. Moreover, diagnosing coronary artery disease in patients with COVID-19 may be clinically challenging. Herein, we present a case of in-hospital stent thrombosis and thrombotic occlusion of the right coronary artery after initial revascularization and adherence to antiplatelet therapy.

Wellens' Syndrome in the Setting of the 2019 Novel Coronavirus (COVID-19).

The novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-Cov2), is the causative pathogen of coronavirus disease 2019 (COVID-19), which is primarily described as a respiratory illness. However, a wide array of cardiovascular complications has also been described in the setting of COVID-19. Wellens' syndrome, also regarded as a left anterior descending coronary T-wave syndrome, is an electrocardiography (EKG) pattern that indicates critical proximal left anterior descending (LAD) artery stenosis. It is characterized by deeply inverted T-waves or biphasic T-waves in the anterior precordial chest leads in a patient with unstable angina. Patients typically present with symptoms consistent with acute coronary syndrome. To our knowledge, we present the first case of Wellens' syndrome in a patient with a COVID-19 infection. Furthermore, this case describes stenosis of the left circumflex artery, a variant of the unusual angiographic findings associated with Wellens', as it is usually associated with occlusion of the proximal LAD. The pathophysiology of cardiovascular complications associated with COVID-19 is not well-understood; nevertheless, it was reported that mortality from coronary artery disease (CAD) complications is significantly higher in these patient populations. Healthcare providers should also be aware of identifying Wellens' syndrome, as urgent coronary angiography is superior to stress testing.

Hematological manifestations and complications of COVID-19.

The virus SARS-CoV-2 commonly causes self-resolving, flu-like illnesses in the majority of patients, but a critical illness can be seen in 5% of cases - especially in the elderly population or in patients with multiple comorbidities. When COVID-19 is severe, it can cause pneumonia and hypoxemic respiratory failure, and can progress to viremia involving multiple organ systems. It causes significant cytopenia, mainly severe lymphopenia, and excessive exhaustion of CD8+ T cells, resulting in an immunocompromised state and cytokine storm. Furthermore, COVID-19 can commonly be complicated with acute thrombotic events, including venous thromboembolism, acute stroke, acute myocardial infarction, clotting of hemodialysis and extracorporeal membrane oxygenation (ECMO) catheters, and acute limb ischemia. This makes SARS-COV-2 a unique virus with an undiscovered pathophysiology. Therefore, patients with COVID-19 need close monitoring of their symptoms and laboratory parameters, and early hospitalization and treatment in severe cases. Early identification of severe cases and the abovementioned complications of COVID-19 could decrease the morbidity and mortality caused by the disease. In the study, we summarize what is currently known about the hematological manifestations and complications of COVID-19.

Steal and strain: A case of coronary artery fistula presenting with coronary steal syndrome and underlying bronchiectasis.

BACKGROUND: Coronary artery fistula is a relatively rare disorder with an incidence rate of 0.05-0.9%, and the majority of fistulae are detected incidentally. Most coronary artery fistulae are congenital, and the acquired variant is very rare. Herein, we present a possible acquired coronary artery to pulmonary artery fistula, most likely secondary to bronchiectasis in the adjacent lung. We will analyze the hemodynamic significance of the fistula in this case and also seek to understand the outcomes of various treatment modalities. CASE PRESENTATION: A 56-year-old male patient presented with hypoxemia secondary to acute pulmonary edema during a hypertensive emergency. He developed myocardial ischemia after treatment with diuretics and nitroglycerin, due to shunting of blood from the right coronary artery to the right lower lobe branch of the right pulmonary artery, via the fistula. This resulted in coronary steal syndrome. Coronary angiogram confirmed the fistula connecting the right coronary artery to the right lower lobe branch of the right pulmonary artery. An attempt at coil embolization was unsuccessful due to the inability to advance the microcatheter beyond the fistula. DISCUSSION: The majority of coronary artery fistulae are asymptomatic as they are hemodynamically not significant and are incidentally detected by coronary angiography, CT angiogram, echocardiogram or multi-detector row computed tomography (MDCT) with 3D reconstruction. The development of congenital fistula can be explained by the Hackensellner involution-persistence hypothesis, but the anatomy in this case and the bronchiectasis in the part of the lung adjacent to the fistula makes an acquired cause very likely due to local inflammation and the age of patient at initial diagnosis. An initial diagnosis of bronchiectasis was made at age 51, which was 5 years prior to the detection of the coronary artery fistula in this patient. Symptoms have been described mostly in the elderly and include chest pain, dyspnea, fatigue, syncope, and palpitations. Such symptomatic fistula should be treated either by percutaneous transluminal embolization or surgical ligation. CONCLUSION: This is a unique case of acquired coronary to pulmonary artery fistula in the setting of bronchiectasis in a patient in which PTE was attempted and failed. More research is required to understand the pathophysiology of acquired fistula. The decision regarding the method of closure should be individualized and decided on a case by case basis.

The Association Between Anemia of Chronic Inflammation and Alzheimer's Disease and Related Dementias.

BACKGROUND: Dementia is a spectrum of neurological diseases characterized by memory impairment and cognitive decline with the pathogenesis and effective management remaining elusive. Several studies have identified a correlation between anemia and Alzheimer's disease and related dementias (ADRD); however, anemia subtypes and association with ADRD have yet to be studied conclusively. OBJECTIVE: To study an association between ADRD and anemia of chronic inflammation. METHODS: We conducted a retrospective case-control study of the patients, diagnosed with ADRD at Brookdale Hospital. Pair-wise comparisons between means of controls and cases in terms of iron studies and laboratory results were performed using a Mann-Whitney U test. Pair-wise comparisons between anemia subgroups (moderate and severe) were performed using a Two Sample proportion Z-Test, where for each couple of normally distributed population. RESULTS: There was a total of 4,517 (1,274 ADRD group; 3,243 Control group) patients. There was significant difference in hemoglobin 10.15 versus 11.04 [p-value <0.001]. Iron studies showed a significant difference in ferritin 395±488.18 versus 263±1023.4 [p < 0.001], total iron binding capacity 225±84.08 versus 266±82.30 [p < 0.001] and serum iron level 64±39.34 versus 53±41.83 [p < 0.001]. Folic acid and vitamin B12 levels were normal in both groups. Severe and moderate anemia in the ADRD group were respectively 6.2% [95% CI: 4.2-8.4] and 13% [95% CI: 9.8-16.2] higher. Overall, incidence of moderate-to-severe anemia was found to be 19% higher in ADRD group [95% CI: 15.8-22.1]. CONCLUSION: We demonstrated an association between ADRD and anemia of chronic inflammation independent of age, renal function, and HgbA1C levels.

Complicated Isolated Liver Abscess Caused by Viridans Group Streptococci Leading to Right Hepatectomy.

Pyogenic liver abscesses (PLAs) secondary to bacterial etiologies are most often seen in developing countries and are less common in North America. The predominant etiology is infection occurring in the setting of direct extension of hepatobiliary or intestinal infection. The most common pathogen isolated from a PLA in the United States is Escherichia coli, whereas Streptococcus viridans is a rare entity in the developed world. Herein we report a rare case of a complicated isolated PLA in a patient without any known comorbidities which lead to hepatectomy. The patient was born and raised in the United States with no recent travel history. The patient was found to have 10 cm isolated multicystic mass on imaging confirmed later as vancomycin-resistant Streptococcus viridans PLA. The patient was treated with multiple intravenous antibiotics and underwent multiple ultrasound-guided percutaneous abscess drainages by interventional radiology, but all unsuccessful. The patient underwent right posterior liver lobectomy, thereafter making a quick recovery and was discharged. Our case underlines the significance of considering liver abscess as a differential even in previously healthy individuals with no known prior comorbid conditions, as prompt recognition is imperative in preventing morbidity and mortality.

Acute Kidney Injury Caused by Levetiracetam in a Patient With Status Epilepticus.

Levetiracetam is a widely used, effective and usually well-tolerated anti-epileptic medicine. It is mostly excreted by kidneys and requires dose adjustment according to the glomerular filtration rate. Very few case reports have been published in the literature about levetiracetam causing acute kidney injury (AKI). We present a case of a 26-year-old male with a seizure disorder on levetiracetam, presented with status epilepticus requiring intubation for airway protection. He received 4 g of intravenous levetiracetam as a loading dose and continued with a maintenance dose of 750 mg intravenous every 12 hours. He had signs of AKI on day two and creatinine eventually reached a maximum level of 12.2 mg/dL. His kidney function improved to his new baseline in a period of 30 days without requiring renal replacement therapy. He did not have significant rhabdomyolysis and his kidney function started improving right after his anti-epileptic therapy was switched to valproic acid pointing towards levetiracetam as the primary cause of kidney injury. Clinicians should be aware that levetiracetam can cause AKI on patients with a seizure disorder, especially when administered in high doses. Kidney function should be monitored closely and patients should be treated aggressively with intravenous fluids when they have any signs of rhabdomyolysis to prevent further kidney damage.

Disseminated Varicella-Zoster Virus Infection Complicated by Encephalitis and Ramsay Hunt Syndrome in an HIV Patient.

Varicella-zoster virus (VZV) is a human α-herpesvirus which cause primary varicella infection (chicken pox) or herpes zoster infection (shingles) after reactivation of the dormant virus. VZV infection is usually self-limited but disseminated infection can be seen in immunocompromised individuals. It can also get complicated by central nervous system (CNS) involvement. We describe a case of a 51-year-old male with human immunodeficiency virus (HIV) who presented with altered mental status and deficits in his right-sided cranial nerves of VI, VII, and VIII. The patient also had disseminated vesicular-pustular rash all over his body at different stages of healing. A diagnosis of disseminated VZV infection complicated by encephalitis and Ramsay Hunt syndrome was made and the patient was treated with intravenous acyclovir and oral prednisone with a rapid improvement. The coexistence of these conditions is rare. The purpose of this report is to increase awareness of the coexistence of these two conditions in HIV infected patients.

Paraneoplastic Pemphigus: An Indication for Treatment in Chronic Lymphocytic Leukemia.

Paraneoplastic disorders are rare multiorgan diseases associated with hematological malignancies such as chronic lymphocytic leukemia (CLL). Some of these paraneoplasms manifest as cutaneous lesions, appearing as a simple rash, ulcers or skin thickening. The pathogenesis for this process has been described as development of certain autoimmune reactions against cell wall antigens and proteins. An example is paraneoplastic pemphigus (PNP) which manifests as cutaneous bullae. Bullae may occur anytime during the course of the malignancy i.e. acute phase or remission. Diagnosis involves evaluation of clinical findings, serology and presence of characteristic histological findings. Its pathogenesis is described as development of auto-antibodies against cell junctional and basement membrane proteins. Presence of paraneoplasms has been associated with poorer prognosis and increased mortality in hematological malignancies including CLL. Currently, there are established indications for the treatment of CLL; however, presence of paraneoplasms as an indication for treatment is unclear. Patients with paraneoplasms who underwent expeditious treatment have exhibited better clinical outcomes. Herein we describe a case of a CLL patient in remission presenting with PNP and its response to treatment.

Multivessel Coronary Artery Fistula Presenting as Coronary Steal Syndrome Leading to Cardiac Arrest.

The coronary steal phenomenon refers to myocardial ischemia caused by the diversion of blood away from normal myocardial circulation. A coronary artery fistula (CAF) is an abnormality of the coronary anatomy characterized by the aberrant termination of a coronary artery or its branches into cardiac chambers or great vessels. Although CAFs are often thought to be asymptomatic, fistulas that diverge a significant amount of blood flow and decrease the normal perfusion of myocardial tissue can cause ischemia and can present with acute coronary syndrome. We describe a unique case of a 70-year-old woman with no coronary artery disease (CAD) undergoing ventricular fibrillation and sudden cardiac arrest from myocardial ischemia secondary to coronary steal brought on by multivessel CAFs. This case was unique in that fistulas originating from the left anterior descending and from the circumflex artery draining into the left heart chambers are the least frequently observed. To our knowledge, only two other reports in the literature, demonstrating sudden cardiac arrest in patients with left anterior descending to left ventricle fistulas with no CAD, exist. The case presented, along with the literature reviewed, demonstrates that CAFs may be an important part of the differential diagnosis of symptoms of chest pain and myocardial ischemia, particularly in middle-aged adults with no history of coronary artery disease or related comorbidities.

Giant Left Main Coronary Artery Aneurysm Presenting as Multiple Implantable Cardioverter Defibrillator Shocks.

Giant aneurysms of the left main coronary artery are one of the rarest findings in cardiology, encountered in less than 0.02% of patients. The presentation is usually the same as coronary artery disease since most coronary aneurysms in the western world are associated with atherosclerosis. Here we report the first case of giant aneurysm of the left main coronary artery presenting as ventricular tachycardia with multiple shocks of the defibrillator in a 57-year-old man with heart failure. We also review the etiology, pathology, and management of coronary aneurysms.

Narrow Escape: A Novel Approach to the Endovascular Treatment of Superior Vena Cava Syndrome Secondary to Pacemaker Leads with Excellent Long-term Outcomes.

Pacemaker or defibrillator placement is a common procedure done in more and more patients due to increased longevity and the prominence of cardiac disease. With more indications for cardiac implantable electrode devices, the devices themselves have evolved into more complex structures with more leads. The mechanical stress, risk of infection, and decreased blood flow through the superior vena cava (SVC) put patients at risk for SVC obstruction. Herein, we present a rare case of complete SVC obstruction secondary to fibrosis due to pacemaker leads which was treated with venoplasty and showed excellent long-term results. We also review the current literature on different approaches to treating SVC obstruction in this group of patients.

Wellens' Syndrome Presenting as Epigastric Pain and Syncope: An Unusual Presentation.

Wellens' syndrome, also regarded as left anterior descending coronary T-wave syndrome, is an electrocardiography (EKG) pattern that indicates critical proximal left anterior descending artery (LAD) stenosis. It is characterized by deeply inverted T-waves or biphasic T-waves in the anterior precordial chest leads in a patient with unstable angina. Patients typically present with symptoms consistent with acute coronary syndrome. We present a unique case of Wellens' syndrome with no angiographic findings of significant stenosis in the proximal LAD but with significant occlusion of the proximal circumflex artery and initial presentation with a chief complaint of epigastric pain and syncope. Physicians need to recognize these characteristic EKG changes during the pre-infarction stage, as they represent myocardial necrosis. Many of these patients eventually develop extensive anterior myocardial infarction with marked left ventricular dysfunction and death if coronary angiography and coronary revascularization are not performed within a few weeks. If Wellens' is seen, patients should undergo urgent cardiac catheterization.

A Broken Heart: Cardiac Arrest As the Initial Presentation of Myasthenic Crisis.

Myasthenic crisis is a life-threatening condition commonly associated with respiratory failure and may present in unusual ways. However, there is paucity in the literature about the cardiac manifestations of myasthenia gravis. We present a case of a 61-year-old male who presented to the emergency room with upper respiratory infection symptoms who soon thereafter suffered sudden cardiac arrest. He was found to have shortened PR interval pre and post arrest onelectrocardiogram (EKG). Only past medical history, discovered post cardiac arrest, was myastenia gravis. All other causes of cardiac arrest were ruled out, and it was deemed to be due to a manifestation of myastenia gravis. The patient was treated with intravenous steroids and plasmapheresis with resolution of shortened PR interval. It is hypothesized that striatial muscle antibodies may trigger inflammation in cardiac muscle and cause conduction abnormalities. In addition, anti-Kv1.4 antibodies have been associated with EKG abnormalities, including QT prolongation and T-wave inversion. To our knowledge, we are the first to report myasthenic crisis manifesting with isolated cardiac arrest with pulseless electrical activity and a shortened PR interval.

Perceptions of the osteopathic profession in New York City's Chinese Communities.

Objective: The purpose of this study was to assess knowledge of and barriers to osteopathic medicine in Chinese immigrant communities in New York City (NYC). Design: A cross-sectional study was designed in which a culturally appropriate survey in Chinese and English versions was administered anonymously to measure immigrant perceptions and knowledge of osteopathic medicine. Setting: Data collection occurred in the municipal delineations for the Chinatown neighbourhood within the New York, New York borough of Manhattan. Participants: Community members were selected using convenience sampling from high-density areas to participate. Information gathered from the survey included demographics, education level, healthcare habits and knowledge of the osteopathic profession. Results: 120 surveys were conducted with 68 males and 52 females, with an average age=40. Respondents in the age range of 18-29 years, those with fluent English-language proficiency, and participants with graduate-level education status demonstrated a higher proportion of knowledge of osteopathic manipulative medicine and osteopathic physicians (doctors of osteopathic medicine) among the study variables. Conclusion: Compared with research on the general US population, a general lack of knowledge of osteopathic medicine exists within NYC's Chinese immigrant community. Although this difference may be ascribed to linguistics and ethnosociological factors, greater outreach and education is needed in urban minority communities to make immigrants aware of all healthcare resources available during the current shortage of US primary care physicians.

Pulmonary arterial hypertension in the elderly: Clinical perspectives.

Pulmonary hypertension (PH) is a rare and devastating disease characterized by progressive increases in pulmonary arterial pressure and pulmonary vascular resistance, which eventually leads to right ventric-ular failure and death. Pulmonary arterial hypertension (PAH) (World Health Organization Group I), a subset of PH, and may be idiopathic in nature or associated with other systemic conditions and is thought to most commonly effect women, the majority of whom are of childbearing age. However, PAH in the elderly population is being increasingly diagnosed creating clinical considerations that had once not been considered. Often in an elderly population the diagnosis of PAH may be delayed due to chronic comorbid conditions such as coronary artery disease or other dyspneic conditions. Though survival and clinical outcomes have improved, the elderly population continues to have disproportionately lower survival rates. High clinical suspicion of PAH warrants a complete diagnostic workup with right heart catheterization. Upon diagnosis, PAH specific therapy should be initiated with possible drug interactions in mind. Adjuvant pulmonary rehabilitation should be considered as a conservative measure with definitive results. Finally, psychosomatic aspects of the disease should also be considered in elderly populations.

De Novo CD5+ Primary Gastrointestinal Diffuse Large B-Cell Lymphoma: Challenges With Treatment and Clinical Course.

The gastrointestinal tract is a common extranodal site for lymphomas. However, primary gastrointestinal lymphomas are rare. Diffuse large B-cell lymphomas (DLBCL) are the most commonly encountered type in the gastrointestinal tract. Most of the DLBCL are CD5 negative. CD5+ DLBCL is very rare and a poor prognostic subtype of lymphoma. We report a rare case of primary small bowel CD5+ DLBCL that evolved from being a localized low International Prognostic Index-scored disease into an advanced and aggressive disease primarily dictated by the presence of CD5 antigen positivity.
