Navigating the Complication: Acute Mastoiditis Causing Cerebral Venous Thrombosis in an Adult.

Acute mastoiditis is an infection of the air cells in the mastoid and is primarily seen in the pediatric population. This disease usually occurs after patients develop otitis media, which can result in acute mastoiditis as a complication. Most patients usually present with generalized symptoms of an infection; however, in some instances, cerebral venous thrombosis can occur.

Fibrillary Glomerulonephritis Associated With Hashimoto's Thyroiditis.

Fibrillary glomerulonephritis is a rare glomerular disease with some correlations between this condition alongside viral infections, malignancy, and autoimmune pathologies. However, the question regarding the pathogenesis is whether patients who develop fibrillary glomerulonephritis do so irrespective of these other pathologies or whether such pathologies induce fibrillary glomerulonephritis through an unknown mechanism. As such, attempts have been made to create associations with this disease to demonstrate further understanding.

A Case of Co-infection Due to Shigella flexneri Colitis Resulting in Bacillus Septic Shock in an Immunocompetent Patient.

Shigella flexneri (S. flexneri) is a facultatively anaerobic gram-negative bacterium that is a member of Enterobacteriaceae. The bacterium has been known to cause mild symptoms, such as diarrhea, to more severe diseases such as hemorrhagic colitis.

A Rare Complication of Proteus Brain Abscess Due to Coccidioidomycosis Causing Hydrocephalus.

is a very common gram-negative facultative anaerobe seen in urinary tract infections. This rod-shaped bacterium tends to cause urolithiasis via its ability to alkalinize the urine. However, in some cases, this bacterium has been shown to cause bacteremia as well as other complicated infections.

A Case of Revelation Due to Pegfilgrastim.

Pegfilgrastim is a granulocyte colony-stimulating factor used in non-myeloid cancer patients to prevent infections and neutropenic fevers. Although this medication is widely used to induce granulocytosis in pancytopenia patients, there are certain instances where such a situation can cause severe side effects. In this case, we present a patient with a history of metastatic colon cancer who is currently taking pegfilgrastim to counter the agranulocytosis caused by his chemotherapy treatment.

A Severe Case of Diabetic Lumbosacral Radiculoplexus Neuropathy: A Diagnosis of Exclusion.

Diabetic lumbosacral radiculoplexus neuropathy (DLSRPN), also known as diabetic amyotrophy, is a rare disease of exclusion that is difficult to diagnose due to its non-specific clinical presentation of neuropathy, autonomic symptoms, and potential weight loss. Due to this, many differential diagnoses are raised before making a diagnosis of such an uncommon disease. However, once the diagnosis is made, the management of this disease can vary.

Two Cases of Anterior Shoulder Dislocation and Fracture Secondary to Generalized Tonic-Clonic Seizure.

Dislocation of the glenohumeral joint secondary to generalized tonic-clonic seizures is well documented in the medical literature, with posterior dislocation being most commonly described. Still, these occurrences tend to be rare and affect a minority of patients, and fractures associated with dislocations after seizures are even less common. As such, the management of these injuries tends to be quite varied, and there is a paucity of documented cases in the literature.

Demystifying Breast Disease Markers.

Breast imaging radiologists regularly perform image-guided biopsies of suspicious breast lesions based on features that are associated with a likelihood of malignancy ranging from 2% to greater than 95% (Breast Imaging Reporting and Data System categories 4 and 5). As diagnostic partners, pathologists perform histopathologic assessment of these tissue samples to confirm a diagnosis. Correlating the imaging findings with the histopathologic results is an integral aspect of multidisciplinary breast care.

The Impact of Social Determinants of Health on the Time Between Diagnostic Breast Imaging and Biopsy at a Safety Net Hospital.

Purpose: Although social determinants of health (SDH) are thought to be associated with health outcomes, there is limited literature on the direct impact of SDH on delays in breast cancer diagnosis via breast imaging. Identifying SDH associated with longer lapses (defined in this study as a time interval between two events) between imaging and biopsy is essential to early-stage detection of breast cancer, which has a significant impact on survival. Previous work demonstrated associations between both housing and food insecurity with longer lapses between diagnostic imaging and biopsy.

Utility of the HScore for Predicting COVID-19 Severity.

Background: Cytokine release syndrome is a life-threatening condition known to cause fever and multiple organ dysfunction and is suspected to be related to the severity of coronavirus disease 2019 (COVID-19). We sought to examine the utility of the HScore and non-cytokine markers of inflammation for predicting COVID-19 outcomes. We hypothesized that cytokine storm, assessed by a modified HScore, would be linked to more severe COVID-19 symptoms and higher mortality.

Pulmonary Giant Cavitary Coccidioides With Fungal Ball and Hemoptysis.

Coccidioidomycosis (CM) is a fungal disease that results from inhalation of spores of and . If symptomatic, disease primarily manifests as community-acquired pneumonia; however, additional pulmonary manifestations such as pleural effusion, empyema, and cavitation may occur. Diabetic patients have an increased risk of severe and cavitary CM.

Subacute Bacterial Endocarditis Presenting as Diffuse Alveolar Hemorrhage and Infection-Related Glomerulonephritis.

We present a case of a 69-year-old male with a past medical history of prostate cancer, chronic mitral valve regurgitation, and recent dental cleaning who presented to the hospital with shortness of breath, anemia, and acute renal failure. Due to unexplained creatinine rise, a renal biopsy was obtained which was suspicious for infection-related glomerulonephritis (IRGN). Further workup confirmed subacute endocarditis according to modified Duke's criteria.

Dual energy CT angiography for lower extremity trauma: comparison with conventional CT.

Purpose: To determine if rapid switching dual-energy CT (rsDECT) provides improvements in vascular attenuation, subjective diagnostic quality, and detection of vascular injuries compared to conventional CT in trauma patients undergoing lower extremity CT angiography.

Materials And Methods: The IRB approved this HIPAA-compliant retrospective study. Informed consent was waived.

Immunotherapy-Induced Acute Tubulointerstitial Nephritis.

Due to its minimal side-effect profile, immunotherapy has become a popular choice for the treatment of advanced melanoma as compared to conventional chemotherapy. The most common side effects associated with immunotherapy include gastrointestinal, pulmonary, and dermatologic manifestations. However, there have been very few documented occurrences of nephrotoxic side effects.

Lupus Cerebritis as the Initial Presentation of Systemic Lupus Erythematosus in a Young Female.

The psychiatric and neurological symptoms of systemic lupus erythematosus (SLE) are referred to as lupus cerebritis. The wide range of symptoms associated with SLE can pose a diagnostic challenge. We present a case of lupus cerebritis in a 31-year-old female presenting with psychosis.

Ischemic Nephropathy Following Occlusion of Abdominal Aortic Aneurysm Graft: A Case Report.

In this report, we present a case of a 55-year-old female with a past medical history of abdominal aortic aneurysm (AAA) graft, femoral-femoral bypass graft, questionable history of chronic kidney disease (CKD), abdominal hernia repair, alcoholic pancreatitis, chronic abdominal pain on opioids, and tobacco abuse who presented with acute on chronic abdominal pain with an unexplained rise of creatinine and anuria. The patient was found to have complete occlusion of AAA graft and was determined to have ischemic nephropathy (IN).

Streptonigrin at low concentration promotes heterochromatin formation.

Heterochromatin is essential for regulating global gene transcription and protecting genome stability, and may play a role in tumor suppression. Drugs promoting heterochromatin are potential cancer therapeutics but very few are known. In order to identify drugs that can promote heterochromatin, we used a cell-based method and screened NCI drug libraries consisting of oncology drugs and natural compounds.

Interrogating a hexokinase-selected small-molecule library for inhibitors of Plasmodium falciparum hexokinase.

Parasites in the genus Plasmodium cause disease throughout the tropic and subtropical regions of the world. P. falciparum, one of the deadliest species of the parasite, relies on glycolysis for the generation of ATP while it inhabits the mammalian red blood cell.
