Pathophysiology and diagnostic criteria of PCOS.
Minerva Obstet Gynecol

Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy.
Introduction: Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine-metabolic syndrome mainly characterized by ovarian dysfunction, which is only one manifestation of a more complex syndrome with a significant systemic impact.
Evidence Acquisition: We review scientific literature on the pathophysiology and diagnosis of PCOS evaluating the most relevant data from original articles, reviews and meta-analyses published until June 2024.
Evidence Synthesis: From a pathophysiological point of view, the concurrence of both metabolic aspects, such as insulin resistance and obesity, and hormonal alterations, such as hyperandrogenemia, might produce the most relevant clinical signs and/symptoms of this syndrome, for instance menstrual irregularities, hair loss, acne and hirsutism.
Proteinase 3 (PR3)-Positive Perinuclear Anti-neutrophil Cytoplasmic Antibodies (pANCA) Vasculitis With Concurrent Invasive Aspergillosis Infection.

Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides are a group of rare diseases that cause inflammation of small to medium vessels. They comprise granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). As the signs and symptoms are varied, the diagnosis of vasculitis is complex and challenging; however, there are type-specific clinical presentations that can be factored into the existing classification criteria.

Prion disease is an uncommon entity characterized by exceptionally rapid neurodegenerative deterioration. There are three categories of prion disease: (1) sporadic: sporadic Creutzfeldt-Jakob disease (sCJD), sporadic fatal insomnia, and protease-sensitive prionopathy; (2) genetic: genetic Creutzfeldt-Jakob disease, familial fatal insomnia, and Gerstmann-Sträussler-Scheinker syndrome; and (3) acquired: Kuru, iatrogenic Creutzfeldt-Jakob disease, and variant Creutzfeldt-Jakob disease. Although it is an incurable disease, a specific pathophysiological mechanism exists involving neuronal loss, glial cell proliferation, absence of inflammatory response, development of vacuoles leading to a spongiform appearance, and the presence of prions.

Department of Psychiatry, Ankara University, Ankara, Turkey.
Objectives: This study compared cognitive flexibility (CF) and emotion recognition (ER) in adolescents with eating disorders (ED) to a healthy group.
Methods: Forty healthy individuals aged 12-18 years with no psychiatric diagnosis and 46 patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN), or binge eating disorder (BED) according to DSM-5 criteria participated. CF was assessed using the Cognitive Flexibility Scale (CFS), Stroop Test, and Berg Card Sorting Test (BCST), while ER was evaluated using the test of perception of affect via nonverbal cues.
