Schwann Cell Hamartoma Presenting as a Colonic Polyp: A Rare Case Report With a Literature Review.

Mucosal Schwann cell hamartomas (MSCHs) are non-common noncancerous growths derived from Schwann cells in the peripheral nervous system, often found unexpectedly during routine colonoscopy examinations. These growths primarily occur in the colon, although they can also appear in the esophagus and are not linked to familial cancer syndromes. Diagnosis relies on specific histological characteristics and staining patterns. It is essential to distinguish MSCHs accurately since their appearance can closely resemble that of malignant tumors. Characteristically, these hamartomas test positive for S-100 protein but do not exhibit markers typical of other gastrointestinal growths, such as gastrointestinal stromal tumors (negative for KIT), leiomyomas (negative for smooth muscle actin), neurofibromas (negative for CD34), and perineuromas (negative for epithelial membrane antigen or claudin-1). This report discusses the case of a 48-year-old woman who was diagnosed with MSCH during a screening colonoscopy.

Cement-Induced Chemical Burn in a Middle-Aged Male: A Case Report and Review of Literature.

This case study reviews a 48-year-old Hispanic male working in construction who presented with left upper medial thigh pain, redness, and swelling after exposure to hazardous chemicals during cement processing. Initially diagnosed with cellulitis and adjacent myositis, the patient met sepsis criteria and received empiric antibiotics. However, negative cultures and an evolving wound appearance shifted the diagnosis towards bullous diseases and chemical injury. Occupational history and physical exam findings pointed towards injury secondary to chemical exposure, common in cement workers with inadequate protective gear. Cement burns, often insidious, are underreported due to their slow progression, mainly affecting the lower extremities. These burns involve chemical, mechanical, and hypersensitivity mechanisms that can mimic infection on imaging. This case highlights the importance of recognizing and managing cement burns promptly, emphasizing protective measures, decontamination, and potential early intervention by burn specialists.

Metabolic Dysfunction-Associated Steatohepatitis and Progression to Hepatocellular Carcinoma: A Literature Review.

The prevalence of metabolic-associated fatty liver disease (MAFLD) is increasing globally due to factors such as urbanization, obesity, poor nutrition, sedentary lifestyles, healthcare accessibility, diagnostic advancements, and genetic influences. Research on MAFLD and HCC risk factors, pathogenesis, and biomarkers has been conducted through a narrative review of relevant studies, with a focus on PubMed and Web of Science databases and exclusion criteria based on article availability and language. Steatosis marks the early stage of MASH advancement, commonly associated with factors of metabolic syndrome such as obesity and type 2 diabetes. Various mechanisms, including heightened lipolysis, hepatic lipogenesis, and consumption of high-calorie diets, contribute to the accumulation of lipids in the liver. Insulin resistance is pivotal in the development of steatosis, as it leads to the release of free fatty acids from adipose tissue. Natural compounds hold promise in regulating lipid metabolism and inflammation to combat these conditions. Liver fibrosis serves as a significant predictor of MASH progression and HCC development, underscoring the need to target fibrosis in treatment approaches. Risk factors for MASH-associated HCC encompass advanced liver fibrosis, older age, male gender, metabolic syndrome, genetic predispositions, and dietary habits, emphasizing the requirement for efficient surveillance and diagnostic measures. Considering these factors, it is important for further studies to determine the biochemical impact of these risk factors in order to establish targeted therapies that can prevent the development of HCC or reduce progression of MASH, indirectly decreasing the risk of HCC.

Associations of Patients with Pericardial Effusion Secondary to Light-Chain or Transthyretin Amyloidosis- A Systematic Review.

BACKGROUND: Pericardial effusion is associated with amyloidosis, specifically amyloid light chain (AL) and transthyretin (ATTR) subtypes. However, the patients might present with different clinical symptoms. OBJECTIVE: To determine the characteristics and associations of patients with pericardial effusion owing to either AL or ATTR amyloidosis. METHODS: This study reviewed 26 studies from databases such as PubMed, MEDLINE, Web of Science, Google Scholar and CINAHL databases after protocol registration. The data were analyzed in IBM SPSS 21. Many statistical tests, such as Student t- and the Mann-Whitney U tests, were used. Multivariate logistic regression analysis was also performed. A p-value< 0.05 was considered significant. RESULTS: A total of 531 patients with pericardial effusion secondary to amyloidosis were included. The mean age was 58.4±24.5 years. Most of the patients were male (72.9%). Common co-morbid conditions included hypertension (16.8%) and active smoking (12.9%). The most common time from symptom onset to the clinical presentation was less than 1 week (45%). ATTR amyloidosis was more common in older patients (p<0.05). Abdominal and chest discomfort were commonly associated with AL and ATTR amyloidosis, respectively (p<0.05). Patients with AL amyloidosis had a higher association with interventricular septal thickening and increased posterior wall thickness (p<0.05). First-degree atrioventricular block, left bundle branch block (LBBB), and atrial fibrillation (AF) were more associated with ATTR amyloidosis (p<0.05). CONCLUSION: Pericardial effusion in patients with AL amyloidosis was associated with hypertrophic remodeling, while conduction abnormalities were associated with ATTR amyloidosis.

Gastrointestinal Bleeding in Patients With Acute Ischemic Stroke: A Literature Review.

Stroke is an infarction of the central nervous system (brain, spinal cord, or retina) that results from a disruption in cerebral blood flow either due to ischemia or hemorrhage. Complications of acute stroke are common and include pneumonia, urinary tract infection, myocardial infarction, deep vein thrombosis, and pulmonary embolism, among several others, all of which increase the risk of poor clinical outcomes. Gastrointestinal bleeding is a well-known complication that can occur during the acute phase of stroke. In this review, we have summarized the existing data regarding the incidence, pathophysiology, risk factors, morbidity, mortality, and management strategies for gastrointestinal bleeding in patients with acute ischemic stroke.

A Rare Case of Cecal Adenocarcinoma Presenting as Intussusception.

Colorectal cancer is widely recognized as one of the most common types of cancer worldwide. The management and outlook for colorectal cancer depend on its specific characteristics and how it presents clinically. Despite the identification of various risk factors and causes, cecal carcinoma, a type of colorectal cancer, is infrequent in Western populations under 50 years of age, and little research has been conducted on its epidemiology. Additionally, intussusception, a medical condition where one part of the intestine slides into another, is relatively rare among younger individuals. In this case report, we present a 36-year-old male who presented with abdominal pain. A physical exam revealed mild right-sided and peri-umbilical tenderness. A computed tomography scan of the abdomen and pelvis with contrast revealed long segment intussusception involving the terminal ileum and cecum. The patient underwent a reduction of intussusception and hemicolectomy. He was diagnosed with invasive cecal adenocarcinoma with metastasis to lymph nodes. He was started on chemotherapy and has been following as an oncology outpatient.

The Role of Timely Angiography in Elderly Patients Presenting With Lower Gastrointestinal Bleeding.

Lower gastrointestinal bleeding (LGIB) is associated with significant morbidity and mortality in the elderly population. Timely diagnosis and establishing the etiology of the LGIB can guide appropriate treatment and management. Our patient is a 91-year-old female who presented to the ER with the complaint of several episodes of hematochezia that started four hours before her presentation. The patient underwent an urgent CT angiography showing active bleeding in the proximal ascending colon. She underwent a super-selective arteriogram followed by embolization of the ascending colon arterial culprit bleeding territory using two coils. Her clinical condition improved, and she had no further episodes of hematochezia. Her case highlights the importance of timely diagnosis of the underlying etiology of a patient presenting with LGIB.

The Role of Global Longitudinal Strain in Subclinical Hypothyroid Patients With Heart Failure.

Introduction There is considerable evidence to suggest the role of thyroid hormone in acute coronary syndrome (ACS), but less is known about its prognostic role in heart failure (HF). We aimed to assess the role of global longitudinal strain (GLS) in patients hospitalized with HF and underlying subclinical hypothyroidism (SCHS). Methods A retrospective analysis of 161 subjects was conducted by dichotomizing them into HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF) subgroups. SCHS was defined as a thyroid stimulating hormone level >4.50 mIU/L with a normal thyroxine level based on the evaluation of limits for lab markers from prior studies. HFpEF and HFrEF were defined as left ventricular ejection fraction (LVEF)>40% and LVEF≤40%, respectively, based on American College of Cardiology (ACC) guidelines. An abnormal speckled transthoracic echocardiographic (TTE) strain was defined as a left ventricular global longitudinal strain (LVGLS) value of >-15%. Results The mean age of the population was 62±8 years, and 55% were female. LVGLS was present in 121 patients with underlying SCHS (p<0.05). The patients with SCHS and abnormal LVGLS were found to have deranged left ventricular echocardiographic parameters (p<0.05). The derangements were greater for SCHS patients with HFrEF and abnormal LVGLS (p<0.05). Readmission rates at 30 days and in-hospital mortality were higher in SCHS patients with abnormal LVGLS (p<0.05). Conclusion The SCHS is associated with abnormal GLS in HF patients (either HFpEF or HFrEF) that results in remodeling and adverse outcomes, including mortality and readmission rates. Further studies are warranted to validate these findings in a larger population data pool.

Clozapine-Induced Granulomatous Interstitial Nephritis: A Case Report.

Granulomatous interstitial nephritis is a rare form of tubulointerstitial nephritis and has been uncommonly observed with clozapine usage. Additionally, the progression of the disease to manifest as renal failure requiring dialysis is also uncommon. We describe a case of a 56-year-old female who presented with syncope and was diagnosed with granulomatous interstitial nephritis on biopsy. While hemodialysis may play a role in the management of the disease, steroids provide a definitive treatment. Large-scale studies are needed to evaluate the role of clozapine in causing interstitial nephritis and the characteristics of these features to establish a therapeutic goal.

Associations of Real-Time Ultrasound and Strain and Shear Wave Elastography with Gastrointestinal Organs: A Systematic Review.

Ultrasound elastography is gaining attention for its diagnostic potential across various medical fields, and its physical properties make it valuable in modern clinical medicine. However, its specific attributes, especially in the context of recent medical advancements, remain relatively unexplored. This study aimed to identify instrument-specific characteristics and applications of real-time ultrasound elastography, shear wave elastography, and strain elastography, particularly within gastroenterology. Following PRISMA guidelines, the study examined elastography articles on databases like PubMed, resulting in 78 included articles. Data on patient demographics, organ involvement, specificity, sensitivity, accuracy, positive predictive value, and negative predictive value were extracted. Statistical analysis involved SPSS version 21, with significance set at p < 0.05. The majority of patients were male (50.50%), with a mean age of 42.73 ± 4.41 years. Shear wave elastography was the most prevalent technique (48.7%), and liver investigations were predominant in gastroenterology (34.6%). Gastrointestinal applications showed higher sensitivity, positive predictive value, and negative predictive values (p < 0.05) but lower specificity (p < 0.05). Real-time ultrasound elastography exhibited increased specificity, accuracy, and predictive values (p < 0.05). Ultrasound elastography appears more accurate and effective in gastroenterological settings. Nonetheless, its performance depends on instrument-specific and operator-dependent factors. While promising, further studies are necessary to ascertain optimal utilization in both gastrointestinal and non-gastrointestinal conditions.

Uremic Pericarditis with Cardiac Tamponade in a Patient on Hemodialysis.

Uremic pericardial effusion and pericarditis in end-stage kidney disease patients remain one of the causes responsible for high rates of morbidity and occasional mortality. While clinical presentation could be variable, clinicians should have a high index of suspicion for uremic pericarditis especially in patients who miss their dialysis sessions. We present a 77-year-old man with end-stage renal disease on dialysis diagnosed with pericarditis and large pericardial effusion complicated by cardiac tamponade and shock. He underwent urgent pericardiocentesis with clinical improvement. The course of the disease can be complicated by shock with multiorgan failure, particularly the liver. The presentation is relatively acute requiring a high level of suspicion, urgent diagnosis, and management to reduce mortality. As the geriatric population increases with associated comorbid conditions, it would be expected that patients undergoing dialysis would increase. Given the uncommon nature of the disease and how these patients have been managed by multiple specialties and care providers, it is important to consider dialysis-related complications in all patients with end-stage renal disease presenting with dyspnea.

Metastatic Prostate Cancer With Reticular Micronodular Opacities of Lung: A Case Report.

Prostate cancer, a common malignancy in males, can metastasize to various sites such as the bone, brain, liver, and less commonly, the lung. Detecting pulmonary metastases presents both diagnostic and therapeutic difficulties. Identifying patients with this condition is crucial for gaining a deeper comprehension of the disease's pathogenesis. In this report, we describe the case of a 64-year-old African American male who exhibited elevated prostate antigen levels and was found to have unique reticular Micronodular opacities in the lungs caused by prostate cancer.

Liquefied Lung Cancer: An Uncommon Form of Squamous Cell Carcinoma of the Lung.

Lung cancer is a significant global health concern, with high incidence and mortality rates. This case report presents the atypical presentation of a 71-year-old female with a history of lung cancer who initially presented with symptoms suggestive of infection secondary to a liquefied lung malignancy and later developed bronchial obstruction. Diagnosis of lung cancer requires a high level of clinical suspicion, and imaging techniques, such as PET and CT scans, provide additional evidence. However, necrotic lesions do not have specific findings on radiology. Treatment options depend on the cancer stage, with surgical resection being the primary approach. Chemotherapy and radiation are used for unresectable cases. Liquefied lung cancer is associated with poor outcomes. Post-obstructive pneumonia with necrotic lesions, particularly in cases without an underlying organism, is a relatively rare phenomenon in lung cancer that requires further investigation. Large-scale studies are needed to explore this aspect further and enhance our understanding of lung cancer complications.

"Beyond the Bladder: Exploring the Intricacies of Emphysematous Cystitis and Its Surprising Associations".

Emphysematous cystitis is defined by the presence of air within the bladder wall or lumen in imaging studies with increased incidence in elderly women and diabetics. It is a result of gas-forming organisms like Klebsiella and E. coli but can be caused by fungi such as Candida and Aspergillus as well with a wide spectrum of clinical presentations. In this article, we present a case of a 77-year-old female with diabetes mellitus who presented to the hospital with a chief complaint of left lower quadrant abdominal pain. Abdominal imaging revealed emphysematous cystitis, paraspinal abscess, and air in the thoracic and lumbar vertebrae. Laboratory results showed leukocytosis, lactic acidosis, and urinalysis significant for urinary tract infection but no positive urine or blood cultures. The patient was admitted to the intensive care unit for septic shock and was treated with mechanical ventilation, vasopressor support, and prompt antimicrobial therapy following which the requirement of vasopressors ceased on the third day of admission. The decision was then made by the family to pursue hospice care, following which mechanical ventilation was discontinued and the patient transferred to inpatient hospice. With this case report, we aim to add to the existing literature regarding the spread of intra-abdominal infections and go over a brief review of the currently available literature. From our review, we would like to conclude that the presence of pneumoracchis, especially in the setting of an intra-abdominal infection, is a poor prognostic marker, and timely diagnosis and treatment of potential causes are required to reduce mortality.

Rare Cause of Acute Loss of Vision in a Patient With Sickle Cell Trait.

Sickle cell disease (SCD) is a prevalent inherited blood disorder with various ocular manifestations, including sickle cell retinopathy (SCR), characterized by retinal microcirculation impairment and ischemic complications. We present the case of a 21-year-old male with sickle cell trait who experienced a sudden, painless loss of vision in his left eye. Ophthalmologic examination revealed vitreous hemorrhage and neovascularization, indicating SCR. Initial treatment with hydroxyurea and exchange transfusions led to partial improvement. However, due to persistent vitreous hemorrhage, the patient underwent a vitrectomy. The sickle cell trait affects a large global population, and its retinopathy is a rare but severe complication. The pathogenesis and risk factors for SCR are similar to those for SCD. The diagnosis of SCR is established through fundoscopic examination and graded based on Goldberg's classification. Management involves a multidisciplinary approach targeting systemic illness and visual defects, including hydroxyurea, photocoagulation, anti-vascular endothelial growth factors, and vitrectomy. Awareness, early diagnosis, and timely intervention are essential to preventing vision-threatening complications in sickle cell trait patients with SCR.

Amlodipine Overdose in a Transgender Woman: A Case Study.

Calcium channel blockers are a major cause of cardiovascular toxicity. The clinical spectrum of these patients is very variable and there is no consensus on the dose required for toxicity. We present a case of a 43-year-old transgender woman who presented with hypotension and tachycardia owing to drug overdose that was later confirmed to be amlodipine. Given the catastrophic cascade of events involved with such toxicities, it is important to highlight amlodipine as one of the causes of drug overdose that can be overlooked.

Lead Cap Use in Interventional Cardiology: Time to Protect Our Head in the Cardiac Catheterisation Laboratory?

Background: Radiation exposure is an occupational hazard for interventional cardiologists and cardiac catheterisation laboratory staff that can manifest with serious long-term health consequences. Personal protective equipment, including lead jackets and glasses, is common, but the use of radiation protective lead caps is inconsistent. Methods: A systematic review qualitative assessment of five observational studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines protocol was performed. Results: It was concluded that lead caps significantly reduce radiation exposure to the head, even when a ceiling-mounted lead shield was present. Conclusion: Although newer protective systems are being studied and introduced, tools, such as lead caps, need to be strongly considered and employed in the catheterisation laboratory as mainstay personal protective equipment.

Unveiling the Truth: Diagnosing Bacterial Meningitis Through Repeat Lumbar Punctures.

Bacterial meningitis is a cause of global concern given its associated high rates of mortality and complications. Timely diagnosis and management are crucial in improving outcomes in patients. Lumbar puncture and radiological investigations form the crux of diagnosis. However, the clinical course becomes complicated if lumbar puncture results are unrevealing and equivocal for bacterial meningitis. We present a case of a 60-year-old female who was diagnosed with bacterial meningitis on repeated lumbar puncture. Clinical vigilance and a high degree of suspicion is needed to ensure that patients with bacterial meningitis are diagnosed and managed appropriately, especially in cases with inconclusive lumbar puncture or radiological investigations.

Toxic Shock Syndrome Secondary to Erythroderma: Unraveling the Underlying Triggers.

Toxic shock syndrome (TSS) is a rare and life-threatening condition characterized by the systemic manifestation of severe infection. It is caused by exotoxin-producing strains of Staphylococcus aureus and Streptococcus pyogenes. Erythroderma, often described as generalized exfoliative dermatitis, is a rare and severe dermatological condition involving more than 90% of the body surface, identified as an uncommon cause of TSS. Here, we describe a case of a 72-year-old male who presented with signs and symptoms of erythroderma presenting as extensive erythematous scaling and lichenified plaques on multiple body surfaces and later developed TSS.

A Case of Isolated Renal Light Chain Amyloidosis With Hematuria and Low Complement Levels.

The prevalence of light chain (AL) amyloidosis, characterized by the deposition of amyloid chains, is gradually increasing. The clinical features of the disease depend upon the location of amyloid deposition and can manifest in many forms. Although laboratory investigations can reveal proteinuria and change in complement levels, hematuria and low complement levels are rarely reported. There are very few cases of renal AL amyloidosis presenting as persistent hematuria. We present the case of a 54-year-old female presenting with abdominal pain, proteinuria, and moderate persistent hematuria on admission who was later diagnosed with AL amyloidosis on biopsy.
