Pre-bariatric surgery acute kidney injury: Can this be prevented?

Key Clinical Message: Pre-bariatric surgery dietary recommendations should take into account daily protein intake and other risk factors for kidney injury. This is important because a high protein intake can potentially lead to kidney injury.

Abstract: Bariatric surgery has been shown to be a highly effective intervention for achieving weight loss and reducing obesity related-comorbidities.

The Utility of Fecal Calprotectin in the Diagnosis and Management of Microscopic Colitis.

Background: The incidence of microscopic colitis has increased over time. To date, there is no specific biomarker for microscopic colitis, and the diagnosis relies on histopathological tissue obtained during colonoscopy which is an invasive and costly procedure. Unlike Crohn's disease and ulcerative colitis, the utility of fecal calprotectin in diagnosing or monitoring microscopic colitis has not been established, and studies on the role of fecal calprotectin in microscopic colitis are limited.

Thrombocytopenia and hyperthyroidism: A case report and literature review.

Key Clinical Message: Immune thrombocytopenic purpura (ITP) is very challenging to diagnose with concurrent comorbidities affecting platelet count including PAH and autoimmune thyroid disease. ITP resolution can be achieved with tailored treatment of the underlying conditions to avoid adverse events.

Abstract: Immune thrombocytopenic purpura (ITP) is an autoimmune disorder characterized by a platelet count of <100 × 10/L in the absence of other causes of thrombocytopenia.

Flexor tenotomies for the treatment of bilateral wrist contracture after traumatic brain injury: A case report.

Traumatic brain injuries have the potential to cause the development of long-term complications. We aim to show that the use of flexor tenotomies in the treatment of flexion contractures following traumatic brain injury is a viable solution.

Cutaneous mastocytoma obscured by allergic contact dermatitis in an infant.

The diagnosis of solitary mastocytoma is usually made clinically, however, atypical presentations may obscure the diagnosis. We present a unique case of solitary cutaneous mastocytoma in an 11-month-old male initially misdiagnosed as atopic dermatitis; the diagnosis was obscured due to the development of an allergic contact dermatitis most likely secondary to topical medications that were being applied to the lesion. The diagnosis of solitary cutaneous mastocytoma is made based on lesion morphology, Darier's sign, and lack of systemic involvement.

An enigmatic presentation of endocarditis: Emphasizing the role of brain magnetic resonance imaging.

Key Clinical Message: Infective endocarditis should be considered in any febrile individual with acute onset neurological symptoms. If suspicion is high, a negative brain computed tomography does not virtually exclude embolism, and magnetic resonance imaging is warranted.

Abstract: A diagnosis of infective endocarditis (IE) is often delayed, particularly in those infected with unusual organisms.

Seizure caused by intraparenchymal hemorrhage from migration of mandibular dental wire through foramen ovale in a child: A case report.

The foramen ovale is a structure that allows for the extracranial passage of multiple significant intracranial structures, most notably the mandibular branch of the trigeminal nerve (CN V). Here we report the case of a 12-year-old male who presented to the emergency department (ED) with a two-day history of nausea and emesis and a one-day history of altered mental status. Prior to presentation, he started speaking only Spanish, which was unusual because he primarily speaks English.

Use of botulinum toxin as a non-surgical treatment option for idiopathic hallux varus: a case report.

Hallux varus presents with midline deviation of the hallux at the first metatarsophalangeal joint. If left untreated, it may lead to pain and difficulty with normal daily activities. Here, we present a case of spontaneous hallux varus in an 84-year-old female treated non-operatively with injection of botulinum toxin in the Abductor Hallucis Brevis.

Right heart catheterization in clinical practice: a review of basic physiology and important issues relevant to interpretation.

Pulmonary artery catheterization is a diagnostic procedure in which a catheter is inserted through a central vein and advanced toward the pulmonary artery to measure right atrial, right ventricular, and pulmonary artery pressures, estimate cardiac output, identify intracardiac shunts, and measure pulmonary vascular resistance. Hemodynamic measurements can provide a better understanding of the pathophysiology of heart failure and pulmonary hypertension, but their proper assessment and optimal use can be challenging due to differences in techniques that can lead to differences in conclusions and therapeutic management strategies. In this review, we will discuss right heart catheterization and its role in clinical practice (e.

Viral Triggered Celiac Disease: A Case Report.

Celiac disease (CD) is an autoimmune condition presenting with a wide variety of nonspecific gastrointestinal symptoms. It can be difficult to diagnose due to the vagueness of complaints such as diarrhea, anemia due to malabsorption, vitamin or electrolyte deficiencies, and/or failure to thrive. This condition is characterized by a sensitivity to ingested gluten-containing compounds.

Association between right heart catheterization hemodynamics and glycosylated hemoglobin levels in adults with heart failure with reduced ejection fraction.

Unlabelled: This study hypothesized that elevated glycosylated hemoglobin (HbA1c) levels are associated with abnormal right heart catheterization (RHC) hemodynamic parameters in patients with heart failure with reduced ejection fraction (HFrEF) and no prior diagnosis of diabetes.

Methods: Retrospective cohort study of adult patients with HFrEF and no prior diagnosis of diabetes who underwent RHC and had HbA1c levels measured 30 days before or after the RHC. This study excluded patients who had received blood transfusions within 90 days prior to HbA1c measurement and patients with known diabetes.

Pemphigus vulgaris presenting with epigastric pain.

Pemphigus vulgaris is an autoimmune mucocutaneous disease with an involvement in gastrointestinal tract especially in oral cavity and esophagus. Ulcers can be the initial presentation even before visible mucosal or cutaneous lesions. The presenting symptoms will be in accordance with the affected organ such as throat pain, hoarseness, dysphagia, odynophagia, or even bleeding.

Cardiac amyloidosis-An underdiagnosed cause of heart failure: A case report and review of literature.

Restrictive cardiomyopathy secondary to cardiac amyloidosis is an underdiagnosed, but treatable, cause of heart failure involving an extracellular deposition of misfolded protein. Hereby, we report a case of a female patient with history of nephrotic syndrome for 1 year who subsequently presented with symptoms of heart failure. The findings on cardiac imaging supported the suspicion of cardiac amyloidosis.

Development of 1,3-acetonedicarboxylate-derived glucoside amphiphiles (ACAs) for membrane protein study.

Detergents are extensively used for membrane protein manipulation. Membrane proteins solubilized in conventional detergents are prone to denaturation and aggregation, rendering downstream characterization of these bio-macromolecules difficult. Although many amphiphiles have been developed to overcome the limited efficacy of conventional detergents for protein stabilization, only a handful of novel detergents have so far proved useful for membrane protein structural studies.

Relationship Between Age at Menopause, Obesity, and Incident Heart Failure: The Atherosclerosis Risk in Communities Study.

Background The mechanisms linking menopausal age and heart failure (HF) incidence are controversial. We investigated for heterogeneity by obesity on the relationship between menopausal age and HF incidence. Methods and Results Using postmenopausal women who attended the Atherosclerosis Risk in Communities Study Visit 4, we estimated hazard ratios of incident HF associated with menopausal age using Cox proportional hazards models, testing for effect modification by obesity and adjusting for HF risk factors.

Pneumatocele in a Ugandan female with SARS-CoV2 infection: A case report.

Pneumatocele may complicate the course of SARS-CoV2 infection. Our article exhibits the value of early radiological imaging for the timely diagnosis and management of COVID-19 and its complications. Conservative management is the mainstay of the treatment of pneumatoceles; however, prompt surgical intervention is imperative for complicated pneumatoceles.

Association Between Tumor Mutation Profile and Clinical Outcomes Among Hispanic-Latino Patients With Metastatic Colorectal Cancer.

In the United States, CRC is the third most common type of cancer and the second leading cause of cancer-related death. Although the incidence of CRC among the Hispanic population has been declining, recently, a dramatic increase in CRC incidents among HL younger than 50 years of age has been reported. The incidence of early-onset CRC is more significant in HL population (45%) than in non-Hispanic Whites (27%) and African-Americans (15%).

Age-Adjusted D-Dimer in the Prediction of Pulmonary Embolism: Systematic Review and Meta-analysis.

Background: Pulmonary embolism (PE), depending on the severity, carries a high mortality and morbidity. Proper evaluation, especially in patients with low probability for PE, is important to avoid unnecessary diagnostic testing.

Objective: To review the diagnostic utility of conventional versus age-adjusted D-dimer cutoff values in patients 50 years and older with suspected pulmonary embolism.

The pancreas and COVID-19: a clinical conundrum.

With the progression of the COVID-19 pandemic, the classic manifestations of COVID-19 (e.g., persistent fever, dry cough, pneumonia, and acute respiratory distress syndrome in the severe disease) have expanded to include less common complications of the extrapulmonary organs.

Admission hyperglycemia is associated with reperfusion failure in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention: a systematic review and meta-analysis.

Background: Admission hyperglycemia (AH) is a common finding in patients with acute coronary syndrome and has been reported to be associated with increased morbidity and mortality. Prior studies suggest that AH could be associated with reperfusion failure. We conducted a systematic review and meta-analysis to explore an association between AH and risk of reperfusion failure in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI).

Multifocal chondrosarcoma of the hand: Case report and review of the literature.

Few multifocal hand chondrosarcomas have been reported. To our knowledge, this report is the first to describe multifocal hand chondrosarcoma in a patient with no evidence of prior enchondroma, Ollier's disease, or Maffucci syndrome.

Antihypertensive use for stroke in United States emergency departments.

Objective: Timely emergency department (ED) control of hypertension in the acute phase of stroke is associated with improved outcomes. It is unclear how emergency physicians use antihypertensive medications to treat severe hypertension associated with stroke. We sought to determine national patterns of antihypertensive use associated with ED visits for stroke in the United States.
