Acute Esophageal Necrosis: An In-depth Review of Pathogenesis, Diagnosis and Management.

Introduction: Acute esophageal necrosis (AEN) is an uncommon but fatal cause of upper gastrointestinal bleeding. The complex pathophysiology of the disorder provides multiple points for intervention. Therefore, it is important to discuss the many multifaceted aspects of the disease. Methods: A scoping review was performed using PubMed, Google Scholar, and ClinicalTrials.gov. We reviewed literature from 1990 to 2021. The keywords used were 'acute esophageal necrosis', 'upper GI bleed', 'pathogenesis', 'EGD', 'prognosis'. Results and conclusions: The review summarized findings of 46 studies. AEN usually targets older males who have underlying cardiovascular disease. The middle part of the esophagus is commonly involved. The pathogenesis of AEN depends on conditions that increase risk of mucosal damage such as ischemia, lack of mucosal protection and excessive gastric reflux. Some medications are also responsible for the disease. Esophagogastroduodenoscopy is usually the gold standard for diagnosis. Findings suggestive of AEN include darkened, sharply demarcated circumferential areas. Supportive measures, including bowel rest, fluid supplementation and proton pump inhibitors are the cornerstone of therapy. A high index of suspicion should be maintained in patients with chronic health problems presenting with signs and symptoms of upper gastrointestinal bleeding because AEN can carry an unfavorable prognosis in these patients.

Extracorporeal Liver Support: An Updated Review of Mechanisms and Current Literature.

Introduction: Acute liver failure is a cause of major mortality in the United States. Although the liver possesses regenerative capabilities, liver transplantation is the mainstay of treating acute liver failure. This modality is associated with many financial and logistic challenges. In this regard, Extracorporeal Liver Support (ECLS) might help in reducing mortality as well as bridge a patient to liver transplant. In some cases, the sequelae of liver failure such as hepatic encephalopathy and multi-organ failure can be postponed long enough for the native liver to self-recover function. With this rationale, we sought to describe the mechanism of various ECLS modalities, provide an overview of the current evidence regarding its use and to highlight future advancements that could overcome hindrances in its use. Methods: A scoping review was performed using PubMed and other databases from 1990 to 2020 with the keywords: 'extracorporeal liver support', 'acute liver failure', 'acute on chronic liver failure', 'albumin dialysis', 'artificial' and 'bioartificial'. Results and conclusions: ECLS has shown significant improvements in bilirubin and urea levels. Various forms of ECLS might also reduce mortality due to liver failure. However, many complications, such as hypotension, anemia, bleeding issues, sepsis, can be anticipated. There are a few barriers to mainstream use of ECLS, such as specific design requirements and high cost that reduce the overall utility of this modality in a small group of liver transplant candidates. Furthermore, a multidisciplinary team approach is required to supervise ECLS, a luxury only available at major academic hospitals. Some advancements for overcoming these barriers include investigation of new scaffolding systems. In order to expand the usage of ECLS, clinical trials focusing on a comparison of different modalities of ECLS with renal replacement therapy in patients with liver failure should be promoted.

COVID-19 and the Endocrine System: A Review of the Current Information and Misinformation.

Coronavirus disease 2019 (COVID-19) infection primarily involves the respiratory system but has many noteworthy extra pulmonary manifestations as well. We write this review to highlight the basis of some pathophysiological mechanisms of COVID-19 infection-induced endocrine dysfunction. Different scientific databases and institutional websites were searched to collect and consolidate the most up-to-date data relating to COVID-19 infection and endocrine systems. Hypopituitarism, central diabetes insipidus, SIADH, thyroid abnormalities, hyperglycemia, adrenal insufficiency, orchitis and alteration in sperm morphology have been reported in case reports of patients with COVID-19 infection. Data focusing on COVID-19 vaccination was also searched to summarize the effect, if any, on the endocrine system. Endocrinopathies noted post COVID-19 vaccination, including cases of adrenal hemorrhage, new onset Type II Diabetes Mellitus and subacute thyroiditis, are also discussed in this review. This review calls attention to the misinformation relating to COVID-19 vaccination with supposed endocrine effects such as infertility and problems with pregnancy. Rebutting these misconceptions can help increase compliance and maximize COVID-19 vaccination to the public.

Digital Rectal Exam in the Acute Hospital Setting: Bridging Patient Experience and the Physician Perspective.

The digital rectal examination is one of the key physical examination tools used in the assessment of gastrointestinal bleed, different rectal diseases and prostate disease. It is an invasive diagnostic test that has a significant level of patient anxiety and discomfort involved. Despite its many diagnostic utilities this exam has been vastly underutilised due to many limiting factors including lack of physician confidence with this bedside physical maneuver. This review includes patient's point of view and providers perspective on digital rectal examination in the inpatient hospital setting. Some of the contributors to negative patient experience include opposite gender of the physician performing the procedure, lack of procedural awareness and expectations and repeat examinations due to improper electronic health care record charting. A better understanding of the limitations and constraints involved from both the patient and physician perspective can help improve patient experience and overall clinical outcomes.

COVID-19 Vaccine Hesitancy in the LGBTQ+ Population: A Systematic Review.

The coronavirus 2019 (COVID-19) pandemic has disproportionately impacted lesbian, gay, bisexual, transgender, queer (LGBTQ+) people. Despite developing safe and effective COVID-19 vaccines, LGBTQ+ communities still faces challenges due to inequitable access and vaccine hesitancy. Vaccine hesitancy is a delay in the acceptance or refusal of vaccines despite the availability of vaccination services. Various studies have explored and tried to address factors influencing vaccine hesitancy. However, the LGBTQ+ population remains under- and misrepresented in many of these studies. According to the few studies that have focused on the LGBTQ+ population, several factors influencing vaccine hesitancy have been identified, with the most common factors in studies being concern about vaccine safety, vaccine efficacy, and history of bad experiences with healthcare providers. In order to rebuild the confidence of LGBTQ+ people in vaccines, governments, healthcare policymakers, and healthcare providers need to start by acknowledging, and then resolving, these disparities; building trust; dismantling systemic suppression and discrimination; and prioritizing the inclusion of LGBTQ+ people in research studies and public health policies.

Systemic Lupus Erythematosus Presenting as Longitudinally Extensive Transverse Myelitis and Nephritis: A Case Report.

Systemic lupus erythematosus (SLE) is an autoimmune disorder that can potentially affect any organ. It usually presents between the ages of 15 and 45 with 9:1 ratio of female to male patients. Its clinical manifestations vary among people of different ethnicities. Longitudinally extensive transverse myelitis (LETM) is a rare life-threatening complication of SLE. We, herein, report a case of 26-year-old male diagnosed with LETM along with lupus nephritis. The patient presented with high-grade fever associated with chills and burning micturition followed by progressive bilateral lower limb weakness and urinary retention. His physical examination showed decreased bilateral lower limb power, absent reflexes, and mute plantars. His abdominal reflexes were also found to be absent and sensory level was identified at T10. T2 weighted magnetic resonance imaging (MRI) of the dorsal spine showed hyper-intense signals between T5-L1 suggestive of extensive longitudinal myelitis. Renal biopsy confirmed the presence of lupus nephritis stage III + V. Anti-nuclear antibodies (ANA) were reactive and anti-dsDNA was positive, indicative of SLE as the underlying cause of his clinical manifestations. The treatment strategy proved to be beneficial in our patient. However, there is still a vast gap between understanding the mechanisms of self-reactive diseases such as SLE and the appropriate therapeutic approach. As Pakistan's first documented case of Lupus Myelitis, we hope to delve deeper into this matter.

Heart transplantation after the circulatory death; The ethical dilemma.

Donors after brain death (DBD) have been the major source of organ donation due to good perfusion of the organs. However, owing to the mismatch in demand and supply of the organ donors and recipients, donors after circulatory death (DCDDs) has increased recently all over the world. Kidneys, liver, and lungs are being used for transplantation from DCDDs. Recently, heart transplantation from DCDDs has been started, which is under the firestorm of scrutiny by the ethicists. The ethical dilemma revolves around the question whether the donors are actually dead when they are declared dead by cardiocirculatory death criteria for organ procurement. The subsequent literature review addresses all the perspectives by differentiating between the donation methods known as DBDs and DCDDs, explaining the implications of the dead-donor rule on the organ donation pool, and categorizing the determinants of death leading to separation of the arguments under the two methods of donations.

Prevalence and Predictors of Home Use of Glucometers in Diabetic Patients.

BACKGROUND: Self-monitoring of blood glucose (SMBG) is a critical component of diabetes care. However, it has been shown that use of glucometers in developing countries such as Pakistan is limited. The aim of this study was to determine the frequency of glucometer usage in the urban diabetic population of Karachi and to identify variables that influenced the likelihood of practice of SMBG. METHODS: A cross-sectional study was conducted among 567 adult diabetic patients selected at random from the out-patient departments of multiple healthcare institutions in Karachi categorized into two settings; Government and Private. Non-diabetics, patients having gestational diabetes, diabetes insipidus and Cushing's syndrome and terminally ill patients were excluded. Pearson Chi-square and Mann-Whitney U test were applied as the primary statistical method. RESULTS: Prevalence of home glucometer usage was 59% (n= 331). High socioeconomic status (p < 0.001), receiving care from private institutions (p < 0.001), higher education (p < 0.001), a family history of diabetes (p =0.001), awareness regarding diabetes (p < 0.001), having diabetes for > five years (p <0.001), and managing diabetes via pharmacological interventions (p <0.001) (versus diet and exercise) were significant positive predictors of glucometer usage. CONCLUSIONS: Our study demonstrates the increasing trend in use of SMBG. Lack of awareness and cost of glucometers were reported to be the main reasons for not practicing SMBG. Given these factors are easily modifiable, government subsidized initiatives and awareness programs can result in a successful public health strategy to promote SMBG.
