The measurement of cerebral blood volume (CBV) has been the topic of numerous neuroimaging studies. To date, however, most in vivo imaging approaches can only measure CBV summed over all types of blood vessels, including arterial, capillary and venous vessels in the microvasculature (i.e. total CBV or CBVtot). As different types of blood vessels have intrinsically different anatomy, function and physiology, the ability to quantify CBV in different segments of the microvascular tree may furnish information that is not obtainable from CBVtot, and may provide a more sensitive and specific measure for the underlying physiology...

Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology...

Background: Although several studies have identified risk factors for high blood pressure (BP), data from Afro-Caribbean populations are limited. Additionally, less is known about how putative risk factors operate in young adults and how social factors influence the risk of high BP. In this study, we estimated the relative risk for elevated BP or hypertension (EBP/HTN), defined as BP ≥ 120/80 mmHg, among young adults with putative cardiovascular disease (CVD) risk factors in Jamaica and evaluated whether relative risks differed by sex...

T1 colorectal carcinomas (CRCs) are an initial site of metastatic spread. Various risk factors for lymph node metastasis have been investigated in T1 CRCs. However, the major step in the entire process of metastasis remains unclear. In terms of carcinoma invasion and metastasis, matrix metalloproteinases (MMPs) have recently gained increasing attention. Notably, MMP-7 is frequently overexpressed in CRCs, but its implication has not been determined in T1 CRCs yet. The present study aimed to clarify the associations between the pathological risk factors of T1 CRCs and MMP-7...

Introduction: A functionally single cardiac ventricle seen on foetal ultrasound scan carries a guarded prognosis. The antenatal diagnosis of anomalous pulmonary venous connection (APVC) remains challenging, if there is no associated structural cardiac abnormality. Antenatally, a combination of complex cardiac anomaly with suspected isomerism should raise the possibility of associated total anomalous pulmonary venous connection (TAPVC). There needs to be a high index of suspicion for TAPVC, in functional single ventricle and suspected isomerism, as this carries a very grim outcome postnatally...

Nephrotic syndrome is a prothrombotic state with predisposition to venous sinus thrombosis and arterial vascular stroke. Watershed infarcts in junction of arterial territory develop in hypotensive hypovolemic state. These border zone infarcts are usually bilateral in the absence of unilateral arterial stenosis or microembolism. We report a 6-year-girl of frequently relapsing nephrotic syndrome who developed sudden onset hemiparesis with aphasia. Magnetic resonance (MR) imaging brain revealed unilateral watershed infarct in territory between the major cerebral arterial vessels with evidence of restricted diffusion and normal vessel anatomy on MR angiography...

Central venous catheter (CVC) insertion is extensively utilized in Intensive Care Units for evaluation of hemodynamic status, administration of intravenous drugs, and for providing nutritional support in critically ill patients. Unfortunately, CVC use is associated with complications including lung injury, bleeding, infection, and thrombosis. We present a patient with an acute ischemic stroke from an inadvertently placed CVC into the right common carotid artery. A 57-year-old male presented to our institution for left hemiplegia and seizures 2 days after a CVC was placed...

The sinus pericranii refers to a set of clinical presentations that share a pathological communication between the scalp veins and the underlying cranial venous sinus. The nature of this connection ranges from the simple dilatation of the emissary veins, to wide connections through a calvarial bone loss leaving almost the cranial venous sinus in direct contact with the subcutaneous tissue. The authors present the case of an occipital pericranii sinus of intraoperative discovery. Congenital, post-traumatic or spontaneous, this anomaly is most often frontal and located on or close to the midline...
