Gender Differences in Non-Obstructive Coronary Artery Disease.

Subjects affected by ischemic heart disease with non-obstructive coronary arteries constitute a population that has received increasing attention over the past two decades. Since the first studies with coronary angiography, female patients have been reported to have non-obstructive coronary artery disease more frequently than their male counterparts, both in stable and acute clinical settings. Although traditionally considered a relatively infrequent and low-risk form of myocardial ischemia, its impact on clinical practice is undeniable, especially when it comes to infarction, where the prognosis is not as benign as previously assumed.

Pigmented purpuric dermatoses: analysis of epidemiological, clinical and histopathological aspects in relation to the prognosis of 70 patients, including infants and adults.

Background: Pigmented purpuric dermatoses (PPDs) are a group of chronic-relapsing, inflammatory purpuras without vasculitis that typically involve the lower limbs. Five major types could be distinguished, according to the clinical and histopathologic analysis. The etiopathogenesis is still unknown and multiple factors have been considered.

Vasospastic Angina and its Relationship with the Coronary Microcirculation.

Vasospastic angina is an important cause of chest pain due to coronary artery vasospasm that is related to poor quality of life and can lead to myocardial infarction, arrhythmias and death. Since its first description as "Prinzmetal or variant angina" which was believed to be a focal spam that occurred in non-obstructed epicardial coronary arteries, physician and researchers were gradually confronted with the clinical reality and came to the conclusion that the coronary artery vasospasm was considerably more polymorphic than initially described. Although mechanism leading to vasospastic angina is not completely understood, nowadays the medical community acknowledges that it exhibits a large variability in clinical practice ranging from focal to diffuse epicardial vasospasm.

The variegated histopathological features of atypical lentiginous melanocytic nevi: a single institution experience.

Background: Atypical lentiginous melanocytic nevi (ALMNs) are atypical pigmented lesions with histopathological features similar to those of dysplastic nevi, with a lentiginous pattern. Variable histopathological features of ALMNs were observed in our practice.

Methods: We described the histopathological features of ALMNs diagnosed in the period 2009-2015.

Atypical Chest Pain in ACS: A Trap Especially for Women.

Not all acute coronary syndromes (ACS) exhibit the classic symptoms of chest pain. The diagnosis of ACS in patients without typical chest pain is often challenging. These patients are at increased risk for delayed or incorrect diagnosis, less aggressive treatment and high in-hospital mortality.

Neutrophilic figurate erythema of infancy.

We report here a new case of neutrophilic figurate erythema of infancy in a 1-year and 9-month-old white boy. Neutrophilic figurate erythema of infancy is a rare inflammatory dermatosis which is part of the figurate inflammatory dermatoses of infancy and is considered a variant of annular erythema of infancy. The disease is clinically characterized by annular erythematous lesions, sometimes with a polycyclic configuration, and histologically by a dermal neutrophilic infiltration with leukocytoclasia.

Cutaneous manifestations in inflammatory bowel diseases: eight cases of psoriasis induced by anti-tumor-necrosis-factor antibody therapy.

Background: Ulcerous rectocolitis and Crohn's disease are the best known forms of inflammatory bowel disease (IBD). Skin manifestations are not uncommon in IBD and may be divided into specific cutaneous signs, aspecific cutaneous signs, and cutaneous signs caused by drugs used for IBD therapy. The specific signs (fistulas, rhagades and ulcers) are the result of the diffusion of the intestinal inflammatory process into the skin.
