Lyme-Associated Pericarditis: A Case Report and Literature Review.

Lyme disease is caused by Borrelia burgdorferi (B. burgdorferi), which is a spirochete transmitted by ticks of the genus Ixodes. Complications related to the cardiovascular system usually occur in the early phase of infection, and the most common cardiovascular complication of Lyme disease is atrioventricular block, especially third-degree heart block. We report a case of a young Caucasian male patient who presented to the emergency department (ED) with complaints of chest pain and shortness of breath. Initial investigations, including chest X-ray, were negative. An EKG revealed ST elevation and PR depression with troponin elevation. The echocardiogram showed a normal ejection fraction with no pericardial effusion. Skin examination was positive for erythema migrans concerning Lyme. Initial Lyme testing was negative in the patient and it should be repeated after four to six weeks, according to the guidelines. This case report highlights the importance of keeping the differentials broad in these patients even if the initial testing is negative, especially since misdiagnosis or delayed diagnosis can cause cardiac complications.

Euglycemic Diabetic Ketoacidosis in a Patient With Urinary Tract Infection.

Diabetes Mellitus (DM) is a complex metabolic disease primarily associated with elevated blood glucose levels in the body. Diabetic ketoacidosis (DKA) is the most feared acute presentation of diabetes mellitus (DM) in both type 1 and type 2 diabetes mellitus. Furthermore, euglycemic diabetic ketoacidosis (EDKA) is a relatively rare complication of DM in which the blood glucose levels are usually less than 250 mg/dl with an elevated anion gap metabolic acidosis. It can be a diagnostic challenge due to normal blood glucose levels and often can be overlooked. Physicians should be aware of EDKA; prompt diagnosis and treatment are critical in the timely management of the condition to prevent complications. We present a case of EDKA in a 74-year-old female precipitated by a urinary tract infection which was identified and treated promptly with insulin and dextrose infusion. In addition to that, an important difference between British and American guidelines has been highlighted.

Angiotensin-Converting Enzyme Inhibitor-Induced Angioedema: A Case Report With a Review of Management Options.

Angiotensin-converting enzyme inhibitors (ACEIs) are widely used for heart failure, renal failure, diabetic nephropathy, stroke, arterial hypertension, and a number of other cardiovascular or related conditions. ACEI-induced angioedema is a rare entity but can result in life-threatening emergencies. It mainly occurs in patients starting on ACEI as an antihypertensive. We present a case of lisinopril-induced angioedema in an African American patient managed in the emergency department. After appropriate evaluation, the patient was declared safe to be observed in the emergency department. Intubation was not performed. Early identification of angioedema is paramount, and emergency physicians should maintain airways or intubate such patients if indicated. There should be a high level of suspicion of angioedema in patients taking ACEIs if they present with symptoms of respiratory compromise.

The Rationale for Using Corticosteroids in COVID-19 Encephalopathy: Lessons From a Case Report With Evidence From Literature.

The coronavirus disease 2019 (COVID-19) virus primarily affects the pulmonary system, but neurological manifestations and complication of COVID-19 has been reported in abundance in the literature. We present a case of a middle-aged Caucasian male who was brought to the emergency department for altered mental status. His chief complaints were neurological rather than respiratory. A positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reverse transcription polymerase chain reaction (RT-PCR) nasal swab confirmed the diagnosis. Brain imaging showed mildly dilated ventricles with no other acute findings. As the patient did not require oxygen, he was treated with remdesivir alone without corticosteroids, which is also a precipitating factor of psychosis but, unfortunately, thickly used in practice. That led to remarkable results in full recovery without exposing the patient to steroid therapy. We strongly believe that remdesivir alone is sufficient in treating COVID-19-induced encephalopathy in a patient who does not require oxygen, and evidence supports this practice.

Self-medication dilemma in dengue fever.

This paper focuses on the trends of self-medication practices in treating symptoms that may lead to fatal complications in dengue. As dengue is a viral infection with increasing incidence, decision regarding its treatment is mostly affected by public health believes and practices to self-treat the condition by different home remedies, over-the-counter (OTC) drugs or using outdated prescription drugs that proved beneficial in the past experience. Poverty, lack of education, and poor access to health facilities pave the way for making such decisions. Future complications can be averted by raising awareness, counseling the patients and dispensing of pharmaceuticals with strict monitoring.

An Overview of Systemic Lupus Erythematosus (SLE) Pathogenesis, Classification, and Management.

Systemic lupus erythematosus (SLE) is a complex autoimmune disease with multisystem involvement. It is multifactorial and involves epigenetic, genetic, ecological, and environmental factors. Primarily it leads to activation of both innate and adaptive immunity, which consequently leads to autoreactive B cell activation by T cells and leads to immune complexes deposition in tissues leading to an autoimmune cascade that may be limited to the single organ or can cause a widespread systemic involvement. SLE is heterogeneous in presentation, with a broad spectrum of clinical manifestations ranging from clinically mild self-resolving symptoms to severe life-threatening organ involvement. Clinical and serological heterogeneity are critical features in SLE, posing a significant challenge in its diagnosis. Antinuclear antibodies (ANA) are the telltale serological marker in more than 95% of SLE patients. The improved set of European Alliance of Associations for Rheumatology (EULAR) classification enabled accurate diagnosis of SLE. The treatment focuses on remission, preventing organ damage, and improving the overall quality of life.

Interventional radiology in low- and middle-income countries.

With advancements in imaging techniques, interventional radiology (IR) has found an increased utility in multiple diseases such as ischemic stroke, tissue biopsies, oncology, trauma, etc. The benefit has been twofold in being minimally invasive and improved outcomes. IR in low- and middle-income countries (LMICs) is still in its nascent phase. The many hurdles include poorly structured post-graduate training, cost of procedures, and lack of awareness among referring physicians. There is a significant need to increase the trained specialists' awareness among the medical community and rationalize the cost of procedures in LMICs with careful consideration, planning, and international economic and technical assistance.

Impact of the COVID-19 pandemic on knowledge, perceptions, and effects of telemedicine among the general population of Pakistan: A national survey.

Background: Telemedicine is the provision of healthcare services through information and communication technology with the potential to mobilize all facets of the health sector to prevent the spread of COVID-19, provide quality healthcare, protect patients, doctors, and the public from exposure to disease, and reduce the burden on the healthcare system. This study aims to identify knowledge, perceptions, willingness to use, and the impact of the COVID-19 pandemic on telemedicine awareness. Methods: A cross-sectional study was conducted from 27 May 2020 to 17 June 2020 using the convenient sampling technique in the general population of Pakistan. Data were collected by designing an online questionnaire consisting of demographic information, knowledge, attitude perceptions, barriers, utilization, and the impact of the COVID-19 pandemic on telemedicine. Results: Of the 602 participants included in the study, 70.1% had heard about telemedicine, 54.3% had a good understanding of the definition of "telemedicine," 81.4% had not used telemedicine in the past, 29.9% did not know that telemedicine was available before the COVID-19 pandemic, and 70.4% responded that the COVID-19 pandemic had changed their attitudes toward telemedicine. Gender (p = 0.017) and family income (p = 0.027) had a significant association with the perception of the benefits of telemedicine. Conclusion: The knowledge and usage of telemedicine are lacking due to inadequate awareness and technology. The need of the hour is to maximize the application of telemedicine to overcome the deficiencies of the healthcare system. Hence, it is essential to increase awareness through various means and develop an appropriate infrastructure to attain maximum benefits from telehealth services.

Ophthalmic manifestations of nutritional deficiencies: A mini review.

Balanced nutrition is crucial for a healthy eye and vision. Many nutritional deficiencies can result in vision impairment. This article reviews the ocular manifestations of vitamin deficiencies, including vitamin A, vitamin B1 and B12, vitamin C, vitamin D, and vitamin E, and minerals such as zinc. It discusses different ophthalmic symptoms and signs, including dry eye disease, corneal xerosis, decreased night vision, subconjunctival hemorrhage, and retinal changes similar to retinitis pigmentosa. We strongly recommend using multi-vitamin supplements for treating many diseases such as age-related macular degeneration.

Chemodenervation for Oromandibular Dystonia Utilizing Botulinum Toxins.

Oromandibular dystonia (OMD) is a chronic focal dystonia that involves the mouth, jaw, and tongue. It may cause repetitive or sustained dystonic movements, which can be very disabling for patients. It is usually a life-long disorder with numerous treatment options that are, most often, partially curative. In our experience, the best modality to treat OMD is botulinum toxin (BoNT) injections, which not only provide long-term relief but also have fewer adverse effects compared to other medications. Although multiple small- and large-scale studies support this fact, there is still a need for evidence from large randomized clinical trials. Jaw-closing dystonia responds very well to BoNT injections compared to other subtypes of OMD. This review discusses in detail the evidence, injection technique, and typical starting doses for botulinum injection.

Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy (CADASIL) Presenting as Migraine.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary arteriopathy with a genetic predilection for the cerebral vessels. It is caused by mutations in the NOTCH3 gene and commonly occurs in middle-aged individuals. Clinical manifestations range from stroke, transient ischemic attack, and migraine to neuropsychiatric symptoms. We present a case of a 40-year-old patient who came in with headache, blurry vision, progressive right-sided weakness, and behavioral changes. The diagnostic workup included several possibilities, including central nervous system (CNS) infection, stroke, transient ischemic attack, and inherited disorders like mitochondrial encephalopathy, lactic acidosis, and stroke-like episode (MELAS). After proper systemic and genetic workup, we diagnosed this as a case of CADASIL.

Alarming levels of stigma toward generalized dystonia: A cross-cultural comparison.

INTRODUCTION: Although stigma has been linked to poor quality of life, studies examining its prevalence in dystonia are lacking. Our objective was to determine prevalence and predictors of stigma against generalized dystonia in diverse cultural settings. METHOD: Participants were 273 (65.9% female) patients and visitors approached at primary care clinics from three populations: León, Nicaragua (92 participants); a mostly-Hispanic Clinic in Omaha, NE USA (85 participants); and a mostly-non-Hispanic population in Omaha, Nebraska (96 participants). Participants learned about generalized dystonia, epilepsy and schizophrenia through reading a small vignette and viewing videos, followed by a questionnaire designed to identify stigma. We compared levels of stigma between dystonia and other conditions at different sites and measured variables that could affect them. RESULTS: Prevalence of stigma was high toward dystonia (33.00%), similar to epilepsy and lower than schizophrenia. The results showed a complex relationship between the studied variables and level of stigma, especially with age. Female gender predicted more stigmatizing answers. Country of origin, level of education and self-identification of Hispanic ethnicity did not affect stigma. Learning more personal information about the dystonia patient decreased dystonia, a proof that unjustified preliminary negative judgment was present. CONCLUSIONS: Stigma against generalized dystonia was very prevalent across all the communities studied. Demographic and socio-cultural variables had different correlations to level of stigma, underlying the complexity of this problem. The alarming levels of stigma against dystonia justify further studies on how to minimize its impact on our patients.

Systemic Lupus Erythematosus: An Overview of the Disease Pathology and Its Management.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with varied natural history and multisystemic involvement. The pathogenesis is multifactorial and complex precipitating the formation of autoantibodies. One of the main factors in SLE is the interaction between environmental triggers and genetic factors. Genome-wide association study technology has led to the identification of more than 80 loci which produce key proteins that lead to small pathophysiological changes and are associated with SLE. There has been an improvement in the management of the disease with newly standardized scores that have been validated in assessing disease activity and quality of life, and have helped in clinical care as well as research. The last five decades have seen a marked improvement in the prognosis of SLE, thanks to better general care and the development of newer immunosuppressive drugs, more specifically biological agents.
