Eosinophilic Esophagitis: The Role of Steroids and the Dose, Duration, and Delivery of Steroid Therapy.

Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition characterized by the eosinophil infiltration of the esophagus (>15 per high power field). Recently, there has been an increase in both the incidence and prevalence of the disease. The common modalities of treatment are dietary modification, proton pump inhibitors, and steroids. However, the United States Food and Drug Administration has not approved any drugs for the treatment of EoE. This review has discussed the role of steroids in the treatment of EoE, focusing on the various formulations of the drug, its dosage, drug delivery, and duration of therapy. The study also covers the common outcomes of steroid therapy and its side effects.

The Role of Capsule Endoscopy in Crohn's Disease: A Review.

Crohn's disease (CD) is a chronic inflammatory disorder with a predilection for the small bowel. Although awareness of this disorder has increased over the years, it remains a diagnostic challenge for many physicians. This is exacerbated by the rising incidence and high recurrence rate following therapy in certain individuals. It is currently agreed that a multimodality approach is the best one, but with the advent of new modalities, that could be changing. Furthermore, given its impact on the mental health of patients and the cost of treatment, it is pertinent that we arrive at not only convenient but accurate modalities in its diagnosis and management. Among these investigative modalities is the relatively novel capsule endoscopy (CE) that not only provides a more patient-friendly alternative but avoids the need for invasiveness. Asides from its diagnostic capability, its influence on therapy and monitoring of known CD patients following treatment has been shown. This article has reviewed the current literature comparing the relevance of CE with other available modalities in diagnosing CD patients. We explored its therapeutic impact and how it influences monitoring post-treatment in CD. This article also discusses the complications of CE and the possible solutions to these complications in the future.

Alzheimer's Disease and Stroke: A Tangled Neurological Conundrum.

A neurodegenerative disorder, Alzheimer's disease (AD), is characterized by dementia in which there is an age-related decline in cognition and higher functions. Stroke is a cerebrovascular disorder that frequently presents in old age and is a known risk factor for AD development. However, the association that AD can be a risk factor for stroke is not well-studied. This review article compiled various studies that pointed out the association between stroke development in patients with dementia, particularly AD-related dementia. The pathophysiological progression of stroke in AD cases and the genetic makeup possibly affecting the interrelation between these disorders were analyzed in detail using currently available data and studies. Therapeutic and management modalities already in use for AD were put together, and the possibility of early intervention in such patients benefitting cerebrovascular pathologies, particularly stroke-related, was explored. Prognostic differences between patients of stroke with and without AD were also reviewed, and how appropriate management can reduce the burden on health care settings when both present simultaneously was emphasized.

Risk of Stroke With Mitral Stenosis: The Underlying Mechanism, Treatment, and Prevention.

Mitral stenosis (MS), a valvular heart disease, is defined by the narrowing of the mitral valve orifice. The common risk factors for stroke include mitral annular calcification (MAC), diabetes mellitus (DM), male gender, hypertension (HTN), hyperlipidemia, and obesity. Endothelial damage, hypercoagulability, and blood stasis in the left atrium promote the development of the thrombus. Among all the risk factors described, MAC is the independent predictor of stroke. The complicated mechanisms responsible for thromboembolism, predisposing factors for thromboembolism, the risk of cerebrovascular accident (CVA) in MS patients, advanced standardized assessment models for identifying those at risk for stroke, and the possible advantages and disadvantages of available therapies have all been discussed in this review article. We have also discussed newer oral anticoagulants (NOACs) like dabigatran, edoxaban, apixaban, and rivaroxaban. Non-pharmacological therapies are also highlighted such as left atrial appendage ligation and occlusion devices. We also conducted a thorough review of the literature on the efficacy and safety of various NOACs in reducing the risk of stroke.

Cirrhosis and Coagulopathy: Mechanisms of Hemostasis Changes in Liver Failure and Their Management.

Cirrhosis is an end-stage liver disease that can cause changes in any component of the hemostatic system. The net effects of the complicated hemostatic changes have long been unknown due to concurrent changes in pro-and antihemostatic drivers. Coagulation disorders are caused by various factors, including decreased clotting and inhibitor factor synthesis, reduced clearance of activated factors, quantitative and qualitative platelet defects, hyperfibrinolysis, and increased intravascular coagulation. This review discusses the pathogenesis of coagulopathy and multiple studies related to its clinical presentations. This article also highlights an additional problem in the diagnostic and therapeutic approach to this group of patients: the fact that traditional coagulation tests and transfusional strategies may not be reliable for assessing and managing bleeding or thrombotic risks. Hence, multiple management options have been assessed for bleeding and thrombosis in liver disease.

Ulcerative Colitis-Induced Colorectal Carcinoma: A Deleterious Concatenation.

Inflammatory bowel disease (IBD) is a chronic inflammatory gastrointestinal ailment that encompasses Crohn's disease (CD) and ulcerative colitis (UC). UC is an idiopathic, chronic inflammatory condition of the colonic mucosa that begins in the rectum and progresses proximally in a continuous way over a portion of the entire colon. Chronic inflammation is linked to cancer, and IBD-related chronic colonic inflammation raises the risk of colorectal cancer. Chronic inflammation has been linked to cancer, and chronic colonic inflammation caused by IBD increases the risk of colorectal cancer (CRC). When CRC arises in people with IBD, unlike sporadic CRC, the lesions are difficult to identify due to mucosal alterations produced by inflammation. The total prevalence of IBD-associated CRC is increasing due to the rapidly increasing frequency of IBD. Screening and surveillance colonoscopy in IBD patients is considered to allow for the early diagnosis of dysplasia and cancer, improving the prognosis of IBD-related CRC by giving patients proactive therapy. This article has reviewed literature pertaining to the mechanisms related to CRC development in UC and its clinical and therapeutic implications.

Multiple Myeloma and Renal Failure: Mechanisms, Diagnosis, and Management.

Multiple myeloma (MM) is the second most common hematologic malignancy that involves monoclonal immunoglobulin (Ig)-producing plasma cells. Due to its multifaceted clinical manifestations and complications, it draws attention to various medical specialties like neurology, nephrology, orthopedics, cardiology, etc. Renal failure (RF) is one of the most common and most serious complications of MM that can be caused either by excess immunoglobulins that are nephrotoxic or some other causes like hypercalcemia, infection, etc. In this review article, we have discussed the pathogenesis of RF in MM, described the different diagnostic tools to diagnose RF in MM, and explained different treatment modalities to treat RF in MM, including certain general measures (i.e., hydration, withholding any nephrotoxic agents), renal replacement therapy, serum free light chain (SFLC) removal by plasma exchange and high cut-off dialyzer (HCO-HD), chemotherapy, hematopoietic stem cell transplantation (HSCT), and renal transplantation.

Association Between Type 1 Diabetes Mellitus and Celiac Disease: Autoimmune Disorders With a Shared Genetic Background.

Type 1 diabetes mellitus (T1DM) and celiac disease (CD) are one of the most recognized related autoimmune disorders as they share a common genetic background that has been found in the HLA genotype, more specifically DQ2 and DQ8 molecules. Studies have shown that environmental factors as early or late exposure to cereals in the first months of life or the acquired viral infections have been implicated in the risk of development of autoantigens. CD, in most cases, is asymptomatic; therefore, it goes underdiagnosed. As a result, it has been linked to late consequences as decreased growth, delayed puberty, and anemia. Also, CD has been considered an independent risk factor for nephropathy and retinopathy. Therefore, in T1DM patients, as high-risk individuals, a CD screening has been recommended, especially to analyze their joint management. A gluten-free diet has been studied and linked to possible benefits in glycemic control or decreasing the hypoglycemic episodes in T1DM and preventing in CD the late bowel mucosal damage as gluten has been well documented as the primary trigger of these autoimmune responses. This article has reviewed the concurrent occurrence of T1DM and CD regarding the pathogenesis, clinical overlaps, screening, and management options.

Tiny Toes to Tau Tangles: Down's Syndrome and Its Association With Alzheimer's Disease.

Down's syndrome (DS) is a common genetic condition caused by the trisomy of chromosome 21, which leads to the development of many multisystemic complications, early-onset Alzheimer's disease (AD) being one of its most common complications. In this article, we have performed an intensive literature review that established a strong relationship between AD and DS. These two conditions are clubbed pathologically, clinically, and diagnostically to understand the association between AD and DS. This article focuses on understanding the impact of AD on a DS patient on both clinical and pathological levels and exploring some advanced treatment modalities. It has also emphasized the importance of early screening and diagnosis for AD in this group of patients to prevent AD development. Regular monitoring, early diagnosis, and a proper treatment plan can slow the AD occurrence in DS patients.

Rheumatoid Arthritis and Associated Lung Diseases: A Comprehensive Review.

Rheumatoid arthritis (RA) is a prevalent autoimmune disorder affecting 0.5-1% of the population in North America and Europe. Pulmonary manifestations in rheumatoid arthritis patients result in significant morbidity and mortality. Management of these pulmonary manifestations in RA patients causes various challenges for the physicians. This review article has discussed the current state of knowledge of these pulmonary manifestations, including interstitial lung diseases, airway-related diseases, pulmonary vasculature, and pleural involvement in RA patients. This review article has also explored various pharmacological options, including steroids, disease-modifying antirheumatic drugs (DMARDs), immunosuppressive drugs, and biologic agents. Non-pharmacological options include conservative treatment, supplemental oxygen, pulmonary rehabilitation, smoking cessation, and lung transplantation.

Systemic Lupus Erythematosus and Cardiovascular Disease.

Systemic lupus erythematosus (SLE) is a condition in which autoimmune inflammation affects nearly every organ in the human body; it is characterized by a relapsing-remitting pattern. Systemic inflammation and tissue damage can arise from autoantibodies, the creation of immune complexes, and the deposition of autoantibodies, all defined as autoimmune diseases. Women of reproductive age are at a high risk of developing lupus, a chronic systemic condition. Among women between the ages of 15 and 44 years, the female-to-male ratio for the occurrence of lupus is as high as 13:1, while it is only 2:1 in children and in the elderly. In addition to accelerated atherosclerosis, SLE is associated with an increased risk of cardiovascular (CV) events such as coronary artery disease (CAD), peripheral artery disease (PAD), and cerebrovascular accident (CVA). Several SLE-specific processes, including impaired immunological regulation, impaired endothelial cell (EC) function, impaired vascular repair, hyperleptinemia, and traditional risk factors, contribute to early atherosclerosis in the disease. CAD can occur at any stage of the disease's progression, with younger individuals being much more at risk than their age-matched counterparts. This review article aims to provide a unique insight into the relationship between SLE and cardiovascular disease (CVD) by discussing the pathophysiological role of CVD in SLE, outlining screening criteria, and highlighting the treatment options for CVD in connection with SLE.

Cardiovascular Involvement in Thyrotoxicosis Resulting in Heart Failure: The Risk Factors and Hemodynamic Implications.

Thyrotoxicosis is a clinical syndrome with persistently elevated concentrations of free triiodothyronine, free thyroxine, or both, which correlates with an increased thyroid metabolic function. This article has discussed the direct effect of increased thyroid hormone on the heart, as the thyroid hormone physiologically exhibits a close harmony with hormones of the cardiovascular system. This action can lead to disturbances in hemodynamic stability, exacerbating the possibility of developing complications such as heart failure and life-threatening arrhythmias. This article has also explored the multifaceted pathogenesis of thyrotoxicosis and various pharmacological treatment options, including beta-blockers and anti-thyroid drugs. This article has reviewed numerous studies that have concluded that the main goal of therapy should always aim to normalize thyroid hormone levels based on the etiology of the thyrotoxicosis, although cardiovascular conditions are associated with a higher rate of mortality.

Relationship Between Vitamin D and Thyroid: An Enigma.

Hypothyroidism is a frequently encountered endocrine disorder in clinical practice. Besides its traditional role in bone health, vitamin D has been shown to have favorable effects in a variety of different systems due to its pleiotropic qualities and ubiquitous receptor expression. Over the years, researchers have been fascinated by the intricate molecular interplay between vitamin D and thyroid. In this regard, attempts have emerged to demonstrate the role of vitamin D in thyroid disorders. This article has reviewed the existing literature on the role of vitamin D in hypothyroidism. We explored studies discussing the physiological interactions between vitamin D and thyroid, as well as the clinical consequences, supplemental and prognostic relevancy of vitamin D in auto-immune thyroid disease (AITD) and hypothyroidism.

Hypertrophic Cardiomyopathy and Atrial Fibrillation: A Review.

Hypertrophic cardiomyopathy (HCM) is an inherited cardiological condition that exhibits various clinical symptoms. The leading cause of atrial fibrillation (AF) in patients with HCM is advanced diastolic dysfunction and left atrial dilatation and remodeling. In addition to the gradual symptomatic and functional decline caused by AF, there is an increased risk of thromboembolic disease and mortality, especially if there is a rapid ventricular rate or obstruction of the left ventricular outflow tract. The mainstay of management of AF in HCM is a combination of non-pharmacological lifestyle and risk factor modification, long-term anticoagulation, and rhythm control with anti-arrhythmic medications, septal ablation, and radiofrequency catheter ablation. This article has examined the development of AF in HCM, its clinical symptomatology, and its impact, highlighting its management and the mortality associated with AF in HCM.

Comorbidity of Epilepsy and Depression: Associated Pathophysiology and Management.

Epilepsy is a neurological disorder characterized by recurrent unprovoked seizures. Depression may arise as a result of other mental or physical problems or as a side effect of the drugs used to treat such illnesses, or it could be caused by epilepsy-related structural abnormalities. However, physicians are hesitant to prescribe antidepressants to patients with epilepsy due to concerns about decreasing seizure thresholds and the harmful drug interactions between antidepressants and antiepileptic medicines. As a result, the question about the optimal care of epileptic patients who suffer from depression remains unanswered. Despite the complicated link between epilepsy and depression, the co-administration of antidepressants and antiepileptic drugs (AEDs) is safe and beneficial when appropriately managed. A focused evaluation for depression (regardless of social, economic, or personal circumstances) might identify people who benefit from medical care and therapeutic assistance. Vagus nerve stimulation and psychological therapies such as cognitive-behavioral therapy, individual or group psychotherapy, patient support groups, family therapy, and counseling are nonpharmacological therapeutic alternatives. In terms of treatment strategy, it is critical to optimize seizure control and limit antiepileptic medications' adverse effects. Psychotherapy for depression in epilepsy is underused, even though it has been shown to be helpful in well-controlled studies. This review article has discussed some parts of the most common pathophysiologies of depression in patients with epilepsy, highlighted the efficacy of psychotherapy and antidepressant drugs, and explored the optimal care of patients with epilepsy who suffer from depression.

Migraine and Stroke: In Search of Shared Pathways, Mechanisms, and Risk Factors.

Migraines are one of the emerging causes of disabilities experienced worldwide, and strokes are the second leading cause of death globally. Migraines with aura have been reported to be associated with a higher risk of ischemic strokes, whereas hemorrhagic strokes are more closely associated with migraines without aura, possible mechanisms that link migraines to strokes. These can be categorized into vascular mechanisms such as vasospasm, endothelial and platelet dysfunction, and alteration in the vessel wall seen in migraineurs, further perpetrated by vascular risk factors such as hypertension and hyperlipidemias. Cerebral hypoperfusion that occurs in migraines can cause an electrical aberrance, leading to a phenomenon known as "spreading depression" which can contribute to strokes. In this review, we discuss bloodstream elevation in procoagulants such as antiphospholipid antibodies, homocysteine, von Willebrand factor, and prothrombin. Maintaining pregnant women who actively experience migraines with aura under close observation may be of some value in achieving better outcomes. Women who experience migraines after starting hormonal contraception are at a higher risk of experiencing strokes and stand to benefit from being switched to non-hormonal methods. In this article, we discuss the mechanisms linking migraines and strokes, briefly discuss the pathogenesis, and explore the risk factors contributing to the association therein. In addition, we examine the relationship between migraines and ischemic strokes, as well as hemorrhagic strokes, and review management considerations.

Myelodysplastic Syndromes and Modalities of Treatment: An Updated Literature Review.

Myelodysplastic syndromes (MDS) represent a large group of rare and diverse clonal stem cell disorders. These are classified into several different phenotypes and typically arise following a multistep genetic process, whereby genetic mutations alter the DNA damage and cellular stress responses, impacting transcription, RNA splicing, epigenetics, and cytokine signaling. However, despite the advances made regarding molecular pathophysiology and prognostic criteria and the influx of new treatment modalities, management is primarily based on prognostic scores, such as the Revised International Prognostic Scoring System. This poses a significant challenge to current healthcare professionals due to poor comprehension of the underlying pathophysiology. Hence, this review integrates the latest research and treatment modalities for MDS and discusses the different genetic mutations outlined in the revised World Health Organization 2016 MDS classification system and the associated treatment modalities. Additionally, future directions of research and clinical management of MDS are discussed.

Chronic Pain: A Complex Condition With a Multi-Tangential Approach.

Chronic pain is known as ongoing pain that lasts longer than three months with increasing healing time. It is approximated that 20% of adults of different sexes, races, and socioeconomic backgrounds fall victim to chronic pain. It is a result of several factors and can have lifelong effects. Pain is a complex matter to measure; therefore, the physician needs to understand the patient's health state to create a management plan tending to each issue adequately. There are many complications of such pain, and it can interfere terribly with an individual's quality of life. This article has reviewed the complex pathogenesis of chronic pain and the spectrum of non-pharmacologic modalities and pharmacological treatment options. It has also explored the efficacy of certain drugs and underlined the importance of nonpharmacological options such as physical exercise, cognitive therapy, and physical modalities to treat chronic pain and all the conditions that accompany this disorder.

Inguinal Hernia Mesh Repair: The Factors to Consider When Deciding Between Open Versus Laparoscopic Repair.

Inguinal hernia repair is one of the most commonly performed surgical procedures worldwide. An inguinal hernia occurs due to a defect in the abdominal wall, which allows the abdominal contents to pass through it. Although the placement of mesh over the defect is the gold standard to close the defect, there are various approaches to achieving it, out of which two of the most widely accepted techniques are laparoscopic inguinal hernia repair (LIHR) and open inguinal hernia repair (OIHR). However, the approach of choice widely fluctuates with regards to various factors such as patient history, type of hernias, and surgeons' preference. It is imperative to understand the variations in outcomes of different approaches and how best they fit an individual patient in deciding the technique to be undertaken. This article has reviewed many studies and compared the two techniques in terms of chronic pain, the time required to return to activity, rate of recurrence, and cost-effectiveness.

"Are We Feeding Them Enough?" Micronutrient Deficiency in Children Aged Six Months to Fourteen Years in India.

In this study, we conducted a systematic literature review of the various micronutrient deficiencies (MNDs) that affect children in India and an examination of whether there is a geographic basis for MNDs. MNDs are a common problem in the developing world, in particular, among children in South Asia. According to the United Nations Children's Fund, millions of children suffer from stunted growth, cognitive delays, weakened immunity, and diseases because of MNDs. These physical ailments have several economic, social, and public health implications, and they can severely hamper a country's growth. This study aims to clarify existing data on this topic and highlight the disparities between children living in urban and rural areas in India. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct this systematic literature review of a total of five studies. Study quality was assessed using appropriate checklists, and the studies strengthened the hypothesis that MNDs are common among children in India. Because the selected studies were heterogeneous, no statistical conclusions are drawn here. However, a central premise is that MNDs in children are prevalent in India and are related to poverty. No link between geographic location and MNDs is established; rather, recommendations are made for further research on the topic.
