BACKGROUND: Stroke involving the cerebral white matter (WM) has increased in prevalence, but most experimental studies have focused on ischemic injury of the gray matter. This study was performed to investigate the WM in a unique rat model of photothrombotic infarct targeting the posterior limb of internal capsule (PLIC), focusing on the identification of the most vulnerable structure in WM by ischemic injury, subsequent glial reaction to the injury, and the fundamental histopathologic feature causing different neurologic outcomes...

BACKGROUND: Eosinophilic gastritis (EG) is clinicopathologically characterized by both marked gastric eosinophilia and clinical symptoms. The endoscopic findings in EG vary among patients, leading to clinical confusion. However, little is known about the relationship between precise endoscopic findings and the pathophysiological process responsible for EG. OBJECTIVE: We aimed to elucidate whether the gross endoscopic findings of EG can be classified into distinct gene expression profiles...

Chronic thyroiditis may present a focal lesion, often-palpable abnormality, simulating nodular disease. The number and morphology of the Hürthle cells (HC) vary in the thyroid aspirate. Distinguishing between neoplastic and non-neoplastic HC lesions is difficult when using the fine-needle aspiration cytology (FNAC). We present the case of a 46-year-old female with a large right nodular goiter and hypothyroidism and high titer of anti-thyroid peroxidase antibody (TPO). The thyroid ultrasound showed a large well-defined nodule (more than 6...

CONTEXT: Carney complex (CNC) is an autosomal dominant condition caused, in most cases, by an inactivating mutation of the PRKAR1A gene, which encodes for the type 1 alpha regulatory subunit of protein kinase A. CNC is characterized by the occurrence of endocrine overactivity, myxomas and typical skin manifestations. Cushing syndrome due to primary pigmented nodular adrenocortical disease (PPNAD) is the most frequent endocrine disease observed in CNC. CASE DESCRIPTION: Here we describe the first case of a patient with CNC and adrenocorticotropic hormone (ACTH)-dependent Cushing disease due to a pituitary corticotroph adenoma...

Nodular lymphocyte Hodgkin lymphoma (NLPHL) is a rare disease for which the optimal therapy is unknown. We hypothesized R-CHOP could decrease rates of relapse and transformation. We retrospectively reviewed patients with NLPHL diagnosed between 1995 and 2015 confirmed by central pathologic review. Fifty-nine had sufficient treatment and follow-up data for analysis. We described progression-free (PFS), overall survival (OS) and histologic transformation according to treatment strategy and explorede prognostic factors for PFS and OS...

Lung infections are an important cause of morbidity and mortality, particularly because of the rising antimicrobial resistance. According to the clinical setting, they can be categorized as community-acquired pneumonia and hospital-acquired pneumonia. Radiological patterns of lung infections are lobar consolidation, bronchopneumonia, interstitial pattern, and nodular pattern. In addition, typical imaging features of several infections serve as "red flag signs" in reaching a diagnosis or altering the management...

BACKGROUND: Sarcoidosis is a systemic inflammatory disease characterized by non-caseating epitheloid granulomas; whereas it usually involves the lungs and lymph nodes, genitourinary involvement is extremely rare. For this reason, no consensus regarding the diagnostic and management options for testicular sarcoidosis has been reached. OBJECTIVE: The aim of this case report was to describe an unusual clinical presentation of sarcoidosis. An 8-year-old boy presented with a 6-month history of painless scrotal enlargement and a 2-month history of photophobia, blurred vision, and pain in both eyes...
