Effects of minipuberty disruption on the expression of sexual behavior in female mice.

Sex steroids influence early organization of neural structures involved in expression of sexual behavior. A critical perinatal period during which testosterone surges occur has been identified in male rodents. Data are lacking for females, whose ovarian activity starts later in the postnatal period.

Reproductive function and behaviors: an update on the role of neural estrogen receptors alpha and beta.

Infertility is becoming a major public health problem, with increasing frequency due to medical, environmental and societal causes. The increasingly late age of childbearing, growing exposure to endocrine disruptors and other reprotoxic products, and increasing number of medical reproductive dysfunctions (endometriosis, polycystic ovary syndrome, etc.) are among the most common causes.

Reversible cerebral vasoconstriction syndrome associated with probable drug poisoning.

Reversible cerebral vasoconstriction syndrome (RCVS) is a clinical condition characterized by arterial involvement of the intracranial vessels, manifesting with vasospasm. The most common clinical manifestation related to the syndrome is the thunderclap headache, which consists of a severe headache that reaches the peak of pain within minutes. The imaging study assumes a leading role in the complementary investigation.

Vertical one-and-a-half syndrome in a patient with pecheron artery ischemia: A case report.

Vertical one-and-a-half syndrome (VOHS) is an uncommon presentation resulting from a unilateral thalamomesencephalic stroke with involvement of the rostral interstitial nucleus of the medial longitudinal fasciculus and posterior commissure. The artery of Percheron (aPe) is a branch of the posterior cerebral artery (PCA) and it is a variant that arises as a solitary trunk supplying both medial thalami and upper midbrain. A 78-year-old female patient, presented at the hospital emergency with approximately 12 hours of sudden onset of diplopia, associated with dizziness.

A case report of male breast cancer in a very young patient: what is changing?

Male breast cancer accounts for 1% of all breast cancer cases, and men tend to be diagnosed at an older age than women (mean age is about 67 years). Several risk factors have been identified, such as genetic and hormonal abnormalities. The present study reported the case of a 25-year-old man who was diagnosed with an advanced invasive ductal carcinoma; however, he did not have any important risk factors.
