Squamous Cell Carcinoma of the External Auditory Canal Presenting as a Persistent Ear Infection: A Case Report and Imaging Features.

Squamous cell carcinoma (SCC) is the most common malignant tumor involving the temporal bone but generally very rare. The temporomandibular joint (TMJ), middle cranial fossa, and facial nerve canal are uncommon areas for the tumor to spread. We present the case of primary SCC of the temporal bone in a 63-year-old male presenting for otorrhea, otalgia, facial weakness, and facial pain after failing outpatient antibiotic therapy for an ear infection.

A rare case of progressive multifocal leukoencephalopathy.

Progressive multifocal leukoencephalopathy (PML) is a rare demyelinating disease of the central nervous system (CNS) due to John Cunningham (JC) virus reactivation most often in immunocompromised patients. The brainstem and the anterior corpus callosum are uncommon locations for white matter lesions. We present a case of PML in a 40-year-old female presenting to the emergency department for a tonic seizure with transient postictal confusion.

Creeping through the cranium: A rare and interesting presentation of a meningioma.

A meningioma is a rare primary CNS tumor that tends to present more so in females in a slowly progressive fashion. The cavernous sinus and cerebellopontine angle are uncommon locations for meningiomas. We present a case of a meningioma in a 60-year-old female presenting to the emergency department for a sudden onset headache, vertigo, facial paresthesias, and chest pain.

A Unique Case of Goodpasture's Syndrome-Induced Cardiorenal Syndrome.

Goodpasture's syndrome (GPS) is a rare small vessel vasculitis characterized by circulating antibodies directed against the glomerular and alveolar basement membrane leading to renal and pulmonary manifestations. Here, we discuss a unique case of a 30-year-old Caucasian male smoker initially presenting with hemoptysis and anemia who was found to have biopsy-proven GPS with elevated anti-glomerular basement membrane (anti-GBM) antibodies. Unfortunately, the patient failed four months of standard treatment for GPS leading to end-stage renal disease (ESRD), while uniquely developing cardiorenal syndrome (CRS) with non-ischemic cardiomyopathy resulting in systolic and diastolic heart failure (HF).

Evaluation of the Efficacy of Remdesivir for the Treatment of Coronavirus Disease 2019.

Background: Coronavirus disease 2019 (COVID-19), caused by a novel coronavirus, SARS-CoV-2, has accounted for more than 1 000 000 deaths in the United States alone. In May 2020, the Food and Drug Administration issued an Emergency Use Authorization to allow the investigational use of intravenous remdesivir for the treatment of suspected or confirmed COVID-19 in hospitalized children and adults. Several other agents, such as hydroxychloroquine, dexamethasone, and tocilizumab have been investigated as potential treatment options; however, dexamethasone is currently the only agent that has been proven to reduce mortality in patients who require supplemental oxygen.

Cemiplimab-Induced Hyperosmolar Hyperglycemic State With Concurrent Diabetic Ketoacidosis in a Patient Receiving Treatment for Cutaneous Squamous Cell Carcinoma.

The immune checkpoint inhibitor (ICI) cemiplimab is a human monoclonal antibody used in the treatment of locally advanced and metastatic cutaneous squamous cell carcinoma (CSCC) not amenable to surgery or radiation therapy. Although cemiplimab shows excellent efficacy with a good tolerability profile, it can cause side effects, including potentially life-threatening endocrinopathies. We discuss the case of a 77-year-old Caucasian female with CSCC treated with only three cycles of cemiplimab who presented with altered mental status and was found to have severe hyperglycemia, hyperosmolarity, ketonemia, glucosuria, and ketonuria concerning for hyperosmolar hyperglycemic syndrome (HHS) with concurrent diabetic ketoacidosis (DKA).

Endoscopic Retrograde Appendicitis Therapy in Subacute Appendicitis With Abscess: A Comprehensive Case Study and Innovative Insights.

This case report explores the feasibility and efficacy of endoscopic retrograde appendicitis therapy (ERAT) in treating a 42-year-old female with subacute appendicitis complicated by an abscess. The patient, initially presenting with abdominal pain, underwent an endoscopic intervention involving drainage, irrigation, and stent placement in the appendix. The study discusses the patient's successful outcome, emphasizing the role of ERAT in managing complicated appendicitis with abscesses.

COVID-19-Associated Acute Myocarditis: Risk Factors, Clinical Outcomes, and Implications for Early Detection and Management.

Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus causing acute respiratory distress with multisystem complications, including cardiac complications. Acute myocarditis is one possible complication of coronavirus disease 2019 (COVID-19). Previous studies revealed that mortality from COVID-19 was higher in patients with cardiac complications.

Acute Esophageal Necrosis and Duodenal Disease in the Setting of Recently Initiated Chemotherapy.

Introduction: Acute esophageal necrosis (AEN), commonly referred to as "black esophagus" or Gurvits syndrome, is a rare condition characterized by diffuse black mucosa in the distal esophagus. Most often, the patient is an older male with multiple comorbidities, presenting with upper gastrointestinal bleeding. The exact pathogenesis is unclear, but it is often thought to be secondary to acute vascular hypo-perfusion or ischemia of the esophageal mucosa in critically ill patients with certain secondary comorbid conditions such as renal insufficiency, diabetes mellitus, dyslipidemia, coronary artery disease, malnourishment, alcohol abuse, or association with an underlying malignancy.

En Coup de Sabre in a Pediatric Patient Treated With Calcipotriene.

En coup de sabre (ECDS) is a form of linear scleroderma or morphea that distinctly appears on the forehead and/or frontoparietal scalp. We report a case of a 6-year-old female that presented with a linear, hyperpigmented scar on her left forehead extending to her scalp with resultant alopecia and discoloration in the affected area. The patient was subsequently treated with topical calcipotriene ointment and had an excellent response with normalization of the sclerotic skin, hair regrowth, and improved hyperpigmentation.

Rapid Hepatomegaly From Ruxolitinib Discontinuation Syndrome.

Introduction: Ruxolitinib (RUX) is a Food and Drug Administration-approved Janus Kinase (JAK) inhibitor shown to be effective in improving hypercatabolic symptoms and splenomegaly in patients with myelofibrosis (MF). RUX therapy provides symptomatic benefits for MF patients but is often discontinued for various reasons including worsening cytopenias. Ruxolitinib Discontinuation Syndrome (RDS) involves an acute cytokine-storm rebound phenomenon that can manifest as an acute relapse of symptoms, worsening splenomegaly, respiratory distress, systemic inflammatory response syndrome, or disseminated intravascular coagulopathy.

Retrospective analysis of operative time and time to discharge for laparoscopic vs robotic approaches to appendectomy and cholecystectomy.

Robotic-assisted appendectomies and cholecystectomies are believed to increase cost compared to the gold standard laparoscopic approach. Two equally qualified surgeons performed both approaches over 2 years to evaluate intraoperative duration, time to discharge, conversion to open procedure, and readmission within 30 days. 110 laparoscopic, 81 robotic-assisted appendectomies; and 105 laparoscopic and 165 robotic-assisted cholecystectomies were performed.

Neuro-Ophthalmologic Symptoms Associated With the Moderna mRNA COVID-19 Vaccine: A Case Report.

Multiple neuro-ophthalmological symptoms, such as visual field defects, optic neuritis, and eye movement abnormalities, have been reported with coronavirus disease 2019 (COVID-19) infection. It is unknown whether the COVID-19 vaccine can result in similar neuro-ophthalmological symptoms post-vaccination. Here, we describe a case of optic neuritis after the administration of the mRNA COVID-19 Moderna vaccine.

A Case of Posttraumatic Pott's Disease.

Tuberculosis infection, which is caused by the bacterium (Mtb), most commonly manifests in patients with respiratory systems. However, it can also colonize other tissues including skeletal. In our case, a 77-year-old Caucasian male presented to the emergency department following a rollover motor vehicle collision with chief complaints of neck and lower back pain.

Anomalous Origin of the Right Coronary Artery From the First Septal Perforator.

A 68-year-old white male presented to the clinic for chest pain and shortness of breath with exertion. Through coronary angiography, the patient was found to have an anomalous origin of the right coronary artery off the first septal perforator branch of the left anterior descending artery. The patient was treated with conservative medical therapy as symptoms had resolved, and the patient did not wish to undergo further procedures.

Autoimmune Dysfunction Due to Severe Malaria.

Despite advances in treatment and prevention, malaria still carries significant morbidity and mortality. Cases of malaria in the United States are rare and cases of severe malaria, mostly attributable to , are even more uncommon. With the coronavirus disease 2019 (COVID-19) pandemic, there have been distractions in evaluation and diagnosis leading to a rise in cases and deaths.
