The impact of exposure to tobacco smoking and maternal trauma in fetal life on risk of migraine.

Introduction: Prenatal period is the key time in human development. Many prenatal factors are well-known and increase the risk of developing diseases' after birth. Few studies indicated the link between the prenatal period and the prevalence of migraine in childhood and adolescence so far.

Clinical Characteristics of Patients with Vertebral Artery Hypoplasia.

Vertebral artery hypoplasia (VAH) belongs to the relatively frequent Doppler ultrasonography (US) findings. However, its clinical significance remains controversial. This was a retrospective study analyzing clinical data of patients undergoing US because of cerebrovascular disease in a single academic neurology center.

A Loop That Matters-An Unusual Case of Bow Hunter's Syndrome.

Bow Hunter's syndrome (BHS), also known as rotational vertebral artery occlusion (VAO), is a rare entity in which vertebral artery is reversibly compressed due to rotation or extension of the head, causing vertebrobasilar insufficiency. Because of VAO, BHS should be considered as a possible life-threatening condition. Diverse aetiologies of BHS may trigger a broad spectrum of non-specific symptoms and may result in frequent misdiagnosis of this disorder in daily clinical practice.

Risk of Migraine in Europeans with Low Melanin Levels-A Population Based Case-Control Study.

Populations with a relatively low concentration of melanin, e.g., inhabitants of Europe, North America, and Australia, are the most vulnerable to the harmful effects of UV radiation.

First case of ischemic stroke which happened during continuous intravenous infusion of rt-PA.

Catheter-directed thrombolysis (CDT) is one of the methods in the treatment of patients with acute lower limb ischemia. It is based on intrathrombus infusion of one of the thrombolytic agents. The most common complication of CDT is bleeding.

Brain metastases of mouse mammary adenocarcinoma is increased by acute stress.

Brain metastases from mammary adenocarcinoma constitute the chief cause of morbidity and mortality. Some evidence suggests that stress may contribute to disease progression and metastases. Here we show that acute restraint stress (30 min) induces statistically significant increase in brain metastases of systemically administered luciferase-tagged 4T1-BR-3P mouse mammary adenocarcinoma cells as evidenced by the total brain-associated photons from 5.

Impact of stress and mast cells on brain metastases.

Metastases continue to be the chief cause of morbidity and mortality for many tumors, including brain metastases of lung and mammary adenocarcinoma. Stress appears to increase metastases, but the mechanism is not understood. Recent evidence suggests that local inflammation is conducive for cancer growth and a unique immune cell, the mast cell, accumulates in the stroma surrounding tumors and is critically located at the blood-brain-barrier (BBB).

[Triptans in migraine--here and now (15 years after they were implemented in therapy)].

Migraine is one of the most common primary/idiopathic headaches as well as one of the most frequent complaints in the society. For the last 15 years there has been a significant change in the acute treatment of migraine attacks. It was a result of an extensive research on serotonin receptors, primarily their 5-HT(1B) and 5-HT(1D) subtypes, and on the pathological mechanisms underlying migraine headache.
