Ocular ischemic syndrome (OIS) is a collection of symptoms of carotid and ophthalmic artery disease of common genesis accompanied by ischemia of eyeball membranes. Specifically, the intraocular blood flow becomes impaired due to inflow reduction or arrest, while the venous outflow remains patent. Causes of OIS include arterial hypertension, atherosclerosis, diabetes, aortoarteritis and other vascular diseases. Clinical features depend on the extent, nature, and site of vascular involvement as well as the concurrent pathology...

A 73-year-old woman presented with a 6-hour history of sudden onset lower abdominal pain. Her comorbidities included chronic obstructive pulmonary disease and hypertension. She was under surveillance for a known thoracoabdominal aneurysm. On presentation, she was hypotensive with a systolic blood pressure of 50 mm Hg and a pulse of 60 beats per minute. On examination, she had a pulsatile mass with bruit in her right lower abdomen. Pedal pulses were palpable in both feet. Blood gas analysis revealed a metabolic acidosis with a pH of 7...

PURPOSE: Preeclampsia is known to be a leading cause of mortality and morbidity among mothers and their infants. Approximately 3-8% of all pregnancies in the US are complicated by preeclampsia and another 5-7% by hypertensive symptoms. However, less is known about its long-term influence on infant neurobehavioral development. The current review attempts to demonstrate new evidence for imprinting gene dysregulation caused by hypertension, which may explain the link between maternal preeclampsia and neurocognitive dysregulation in offspring...

Ischemic strokes occur when there is a sudden obstruction of an artery supplying blood flow to an area of the brain, leading to a focal neurological deficit. Strokes can be thrombotic or embolic in etiology and are associated with underlying conditions such as hypertension and atherosclerosis. Possible etiologies of strokes include cardioembolic disease, hematologic disorders, connective tissue disorders, and substance abuse or can be cryptogenic. Most stroke cases are seen in patients over 65 years of age...

Cerebral artery aneurysm rupture is usually associated with significant subarachnoid hemorrhage; however, there are rare cases where there is a lack of hemorrhage into the subarachnoid space. While subdural hemorrhage can occur with ruptured aneurysms, isolated subdural hemorrhage is more often associated with trauma. In this case, a 51-year-old obese woman, who recently visited an Urgent Care Center for elevated blood pressure, was found dead roughly a month later. She had been complaining of headaches, and received medication for her blood pressure at the visit...

Idiopathic intracranial hypertension (IIH) is characterised by increased intracranial pressure with normal cerebrospinal fluid, and no evidence of space occupying process, meningeal pathology or venous thrombosis. The condition is associated with obesity, especially in women of childbearing age. IIH is a rare but serious cause of headache, and constitutes a differential diagnosis for sudden-onset headache, particularly if the patient has visual disturbances not related to migraine and reports pulsatile tinnitus, cranial nerve palsy or radiculopathy...

Hemolytic uremic syndrome (HUS) is defined by the simultaneous occurrence of hemolytic anemia, thrombocytopenia, and acute kidney injury due to thrombotic microangiopathy (TMA) mainly occurring in renal and cerebral microvessels. Although the most common cause of HUS in children is Shiga toxin-producing Escherichia coli, atypical forms in which Shiga toxin is not the trigger may occur. Research over the last few years has shown that complement dysregulation secondary to mutations of genes coding for proteins involved in the regulation of the alternative pathway of complement account for most forms of atypical HUS (aHUS)...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

BACKGROUND: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors. Hypertension secondary to pheochromocytoma is often paroxysmal, and patients occasionally present with sudden attacks of alternating hypertension and hypotension. Spontaneous, extensive necrosis within the tumor that is associated with catecholamine crisis is an infrequent complication of adrenal pheochromocytoma, but its pathogenesis remains unclear. CASE PRESENTATION: A 69-year-old Japanese man developed acute-onset episodic headaches, palpitations, and chest pains...

Overhydration, hypertension, anemia, or dyselectrolytemias sometimes cause cardiovascular impairment in childhood hemolytic-uremic syndrome. Here, we report the case of a 4.5-year-old boy with hemolytic-uremic syndrome and sudden onset, 6 h later, of hemodynamic compromise secondary to a cardiac thrombotic micro-angiopathy. The child died. In the literature, we found 18 further cases with cardiac compromise ≤25 days after diagnosis. The following causes were found: micro-angiopathy, pericardial blood causing tamponade, and myocarditis...

BACKGROUND: Despite the common occurrence of hymenopteran stings worldwide, primary neurologic manifestations including stroke are rare. We report a case of a healthy male who developed a right middle cerebral artery (MCA) territory ischemic stroke after getting stung by a wasp. CASE REPORT: A 44-year-old man with hypertension presented to the hospital with sudden-onset left hemiparesis, left facial weakness, and dysarthria after being stung by a wasp. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) scans of the brain revealed a right MCA territory infarct and a lack of flow in the distal right internal carotid artery and MCA...

BACKGROUND: A lumbar drainage catheter is frequently placed intra-operatively to decrease fluid pressure on the brain in aneurysmal subarachnoid cases. In rare cases, this catheter placement can lead to intracranial hypotension, resulting in brain stem herniation termed "brain sag" and it can lead to neurological injury and may prove to be fatal. We present our patient with brain sag secondary to intraoperative lumbar drainage. CASE DESCRIPTION: A 56-year-old woman was admitted with a sudden onset of severe headache...

BACKGROUND: High blood pressure is an important public health problem because of associated risks of stroke and cardiovascular events. Antihypertensive drugs are often used in the belief that lowering blood pressure will prevent cardiac events, including myocardial infarction and sudden death (death of unknown cause within one hour of the onset of acute symptoms or within 24 hours of observation of the patient as alive and symptom free). OBJECTIVES: To assess the effects of antihypertensive pharmacotherapy in preventing sudden death, non-fatal myocardial infarction and fatal myocardial infarction among hypertensive individuals...

Ventricular arrhythmias are one of the most common causes of death in developed countries. The use of implantable cardiac defibrillators is the most effective treatment to prevent sudden cardiac death. To date, the ejection fraction is the only approved clinical variable used to determine suitability for defibrillator placement in subjects with heart failure. The purpose of this study was to assess whether genetic polymorphisms found in the ryanodine receptor type 2 (Q2958R) and histidine-rich calcium-binding protein (S96A) might serve as markers for arrhythmias...

The annual incidence of subarachnoid hemorrhage (SAH) caused by intracranial aneurysm rupture is approximately 10.5/10 million people in China, making SAH the third most frequently occurring hemorrhage of the intracranial type after cerebral embolism and hypertensive intracerebral hemorrhage. SAH caused by ruptured aneurysm leads to a mortality rate as high as 67 %, and, because of the sudden onset of this disease, approximately 12-15 % of patients die before they can receive effective treatment. Early brain injury (EBI) is the brain damage occurring within the first 72 h after SAH...
