We herein describe the case of a 60-year-old man who presented clinical and histopathological evidence of Henoch-Schönlein purpura. Antineutrophil antibodies (ANCA) showed positive results on an enzyme-linked immunosorbent assay and immunofluorescence for anti-myeloperoxidase and anti-proteinase 3 antibodies. Dual positivity for both cytoplasmatic (C-ANCA) and perinuclear (P-ANCA) antineutrophi...

A 54-year-old Caucasian female was admitted for fevers, night sweats, decreased appetite, weight loss of 20 pounds in 1 month, diffuse rash, and purpuric lesions on her lower extremities. Physical examination revealed a diffuse maculopapular rash on the anterior chest and trunk and a palpable, 1-cm, inguinal lymph node. Initial laboratory studies revealed hemoglobin of 9.1 g/dL, hematocrit of 2...

Muscle wasting that occurs during aging or from disease pathology presents with an accumulation of lipid species termed ceroid or lipofuscin. This unique species of lipid has been characterized in various cell types but its properties and organization in skeletal muscle remains unclear. Using immunofluorescence and transmission electron microscopy, we were able to visualize and characterize an ...

Proteins with molecular weights of around 100,000 (designated 100K) are found in all coated vesicles. Five monoclonal antibodies have been raised against the major 100K proteins of bovine brain coated vesicles, which migrate on SDS gels as three closely spaced bands. One antibody stains the middle band (band B), two stain both upper and lower bands (bands A and C), and two stain the lower band ...

The most common atypical pneumonias are caused by three zoonotic pathogens, Chlamydia psittaci (psittacosis), Francisella tularensis (tularemia), and Coxiella burnetii (Q fever), and three nonzoonotic pathogens, Chlamydia pneumoniae, Mycoplasma pneumoniae, and Legionella. These atypical agents, unlike the typical pathogens, often cause extrapulmonary manifestations. Atypical CAPs are systemic i...

PURPOSE Landmark indicators have not yet to be developed to detect the regression of cervical intraepithelial neoplasia (CIN). We propose that quantitative viral load and indicative histological criteria can be used to differentiate between atypical squamous cells of undetermined significance (ASCUS) and a CIN of grade 1. MATERIALS AND METHODS We collected 115 tissue biopsies from women who t...

Although extensive clinical data have verified the safety and adverse effects of coronavirus disease 2019 (COVID-19) vaccines, unexpected neurovascular events rarely been reported. This report presents an unusual case in which we inferred that spontaneous multiple cerebral arterial dissections with a ruptured blister aneurysm occurred after COVID-19 vaccination. A 34-year-old woman presented se...
