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...

OBJECTIVES: The aim of the study was to determine the characteristics of patients who did not match the audiometric criteria of idiopathic sudden sensorineural hearing loss (SSNHL) but complained of acute hearing loss. METHODS: By thorough medical chart reviews, historical cohort study was performed with consecutive data of 589 patients complaining of acute unilateral sensorineural hearing loss without identifiable causes between 2005 and 2013. Those patients demonstrating a hearing loss of at least 30 dB at three consecutive frequencies based on pure tone audiometry were classified as group I; the others were classified as group II...

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...

Pancreaticoduodenal artery aneurysm is a rare complication of coeliac artery stenosis secondary to a low lying median arcuate coeliac ligament. This article reports the case of a 69-year old man who presented with left arm and leg weakness, clinically in keeping with right hemisphere stroke. Initial CT brain scan was within normal limits. The patient did not receive thrombolysis as he was outside the time window. 3 hours later the patient experienced sudden onset epigastric pain and acute shock. CT aorta abdominal was diagnostic of a ruptured inferior pancreaticoduodenal artery aneurysm...

Hoarseness is a common phenomenon that can be caused by uncommon pathology. One seldom cause is Ortner's syndrome, a rare cardiovocal disease that can lead to hoarseness due to left recurrent laryngeal nerve palsy induced by mechanical compression of the nerve by cardiovascular structures. This case report describes a case of a 41-year-old woman with sudden onset of hoarseness. The patient had known pulmonary hypertension and Eisenmenger's syndrome.

Altered myocardial structure and function, secondary to chronically elevated blood pressure, are leading causes of heart failure and death. B-type natriuretic peptide (BNP), a guanylyl cyclase A agonist, is a cardiac hormone integral to cardiovascular regulation. Studies have demonstrated a causal relationship between reduced production or impaired BNP release and the development of human hypertension. However, the consequences of BNP insufficiency on blood pressure and hypertension-associated complications remain poorly understood...

BACKGROUND: Sudden onset of aphasia is usually due to stroke. Rapid diagnostic workup is necessary if reperfusion therapy is considered. Ictal aphasia is a rare condition but has to be excluded. Perfusion imaging may differentiate acute ischemia from other causes. In dubious cases, EEG is required but is time-consuming and laborious. We report a case where we considered de novo status epilepticus as a cause of aphasia without any lesion even at follow-up. A 62-year-old right-handed woman presented to the emergency department after nurses found her aphasic...

With a history that began in 800 A.D., coffee is the most popular drink known and as a result, the issues regarding its physiologic effects deserve attention. Maintaining alertness is a well-known benefit and in addition, the cardiovascular (CV) effects of the active compounds, which include polyphenols and caffeine, must be considered. Genetics are relevant and where slow caffeine metabolism is inherent, the risk of nonfatal myocardial (MI) has been shown to be increased. Overall risk for coronary heart disease (CHD) is not supported and unless there is excessive intake, congestive heart failure (CHF) is not adversely affected; in moderation, there may be some benefit for CHF...

Pregnancy Induced Hypertension (PIH) is a condition characterised by raised blood pressure in pregnancy. It affects approximately one out of every 14 pregnant women. Although PIH more commonly occurs during first pregnancy, it can also occur in subsequent pregnancies. It can present with variable complications related to vasospasm. But focal neurologic deficits are extremely rare in patients with PIH. We report a case of quadriparesis due to posterior reversible encephalopathy syndrome (PRES). A 36 year old full term pregnant female was admitted for emergency lower segment caesarean section (LSCS) as a result of uncontrolled PIH with early clinical signs of left ventricular failure...

New onset of sudden or progressive headache can have various causes, including disorders of intracranial pressure (ICP). Headache is the most common-and often the presenting-symptom of both intracranial hypertension and intracranial hypotension syndromes, which can be symptomatic or idiopathic. Despite the widespread availability of diagnostic tests, including ocular ophthalmoscopy, neuroimaging, and measurement of CSF pressure, delays in diagnosis or misdiagnosis of idiopathic intracranial hypertension and spontaneous intracranial hypotension remain common...

Hepatorenal syndrome (HRS) is defined as development of renal dysfunction in patients with chronic liver diseases due to decreased effective arterial blood volume. It is the most severe complication of cirrhosis because of its very poor prognosis. In spite of several hypotheses and research, the pathogenesis of HRS is still poorly understood. The onset of HRS is a progressive process rather than a suddenly arising phenomenon. Since there are no specific tests for HRS diagnosis, it is diagnosed by the exclusion of other causes of acute kidney injury in cirrhotic patients...
