AIM: Pulmonary arterial hypertension (PAH), a deadly disorder is associated with excessive growth of human pulmonary artery endothelial (HPAECs) and smooth muscle (HPASMCs) cells. Current therapies primarily aim at promoting vasodilation, which only ameliorates clinical symptoms without a cure. 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) is an endogenous aryl hydrocarbon receptor (AhR) ligand, and mediates many cellular function including cell growth. However, the roles of ITE in human lung endothelial cells remain elusive...

A 81-year-old man was admitted to our university for a second opinion after diagnosis of bladder melanoma in December 2014. His medical history included arterial hypertension, hypothyroidism, peripheral arterial disease treated with a bypass, and corneal transplantation. His medical history was negative for malignant melanoma. He experienced gross hematuria in the absence of any other clinical manifestations, and urine cytology identified atypical cells. The patient underwent transurethral resection of the bladder with diagnosis of melanoma...

BACKGROUND: Spinal dural arteriovenous fistulas (SDAVFs) are abnormal arteriovenous shunts between a radicular artery and the radicular vein, located in the dorsal surface of the dura sleeve, which drains in a retrograde manner into the coronal venous plexus of the spinal cord without an interposed capillary network. This result is a venous hypertension that reduces spinal cord perfusion and leads to ischemia and edema. Spontaneous resolution is extremely rare and, once symptomatic, the typical course is further progression with increased neurological impairment...

Introduction: Vascular hyperreactivity is a risk factor and a factor predicting hypertension (high blood pressure). Unlike other continents where several studies were carried out, it has rarely been studied in black Africa in general and in Cameroon in particular. Methods: Vascular reactivity was measured by the cold test. Vascular hyperreactivity was defined as an increase in blood pressure > 20 mmHg for systolic and/or > 15 mmHg for diastolic. Khi(2), Man-Withney, Wilcoxon's signed ranks and logistic regression tests were used for statistical analysis...

Diesel exhaust (DE) is one of the main sources of urban air pollution. An increasing number of evidence showed the association of air pollution with cardiovascular diseases. Pulmonary arterial hypertension (PAH) is one of the most disastrous vascular diseases, which results in right ventricular failure and death. However, the relationship of DE inhalation exposure with PAH is still unknown. In this study, male adult mice were exposed by inhalation to filtered ambient air (negative control), 10% O2 hypoxia (PAH-phenotype positive control), 350 μg/m(3) particulate matter whole DE, or the combination of DE and hypoxic condition...

Activation of baroreceptors in the carotid modulates the autonomic nervous system. Baroreflex activation therapy (BAT), which activates baroreceptors in the carotid, has become available in the treatment of resistant hypertension. Besides this, a carotid implant modulating baroreceptors as well as pharmacological modulation of carotid bodies were quite recently presented. This review will underscore currently available and promising approaches that activate baroreceptors in the carotid, and thereby contribute to beneficial effects in patients with arterial hypertension, and discusses potential organoprotective BAT effects beyond blood pressure (BP) reduction...

BACKGROUND: Vitamin D deficiency is a risk factor for hypertension. METHODS: We assessed 8155 participants in a community-based program to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) status and blood pressure (BP) and the influence of vitamin D supplementation on hypertension. Participants were provided vitamin D supplements to reach a target serum 25(OH)D > 100 nmol/L. A nested case-control study was conducted to examine the effect of achieving physiological vitamin D status in those who were hypertensive and not taking BP-lowering medication, and hypertensive participants that initiated BP-lowering medication after program entry...

Phosphodiesterase type 5 inhibitors (PDE5i) (e.g., sildenafil, tadalafil, vardenafil, and avanafil) are drugs commonly used to treat erectile dysfunction, pulmonary arterial hypertension, and benign prostatic hyperplasia. PDE5i are not prohibited by the World Anti-Doping Agency (WADA) but are alleged to be frequently misused by healthy athletes to improve sporting performance. In vitro and in vivo studies have reported various effects of PDE5i on cardiovascular, muscular, metabolic, and neuroendocrine systems and the potential, therefore, to enhance performance of healthy athletes during training and competition...

We present a detailed report of an awake craniotomy for recurrent third ventricular colloid cyst in a patient with severe pulmonary arterial hypertension in the setting of Eisenmenger syndrome, performed 6 weeks after we managed the same patient for a more conservative procedure. This patient has a high risk of perioperative mortality and may be particularly susceptible to perioperative hemodynamic changes or fluid shifts. The risks of general anesthesia induction and emergence must be balanced against the risks inherent in an awake craniotomy on a per case basis...

The temporary total artificial heart (TAH-t) has been valuable as a bridge to transplantation in patients with biventricular failure. However, the challenges of accurately assessing pulmonary vascular resistance after TAH-t implantation can preclude these patients from heart transplantation, especially those with pre-existing pulmonary hypertension. The CardioMEMS Heart Failure System (St. Jude's Medical, Little Canada, MN) comprises a wireless pressure sensor that is implanted percutaneously in the pulmonary artery and transmits real-time measurements of pulmonary artery pressures...

Schistosomiasis is one of the most prevelant parazitic diseases in the world. It is endemic in more than 70 countries, and more than 200 million people worldwide are infected with Schistosoma. Pulmonary hypertension (PHT) is one of the chronic complications of schistosomiasis. The exact pathogenesis of schistosomiasis-associated pulmonary hypertension (S-PHT) remains unclear, although several mechanisms such as parazitic arterial embolisation, pulmonary arteriopathy, and portopulmonary hypertension have been suggested...

PURPOSE: Hypertension (HT) strongly affects the vascular endothelium, resulting in chronic inflammatory disease. Dynamic vessel analysis (DVA) is a modern methodological approach to analyze vascular function in the retinal microcirculation. The aim of this study was to examine whether a defective retinal vessels response is associated with HT-induced endothelial dysfunction. MATERIALS AND METHODS: Retinal vessel reactions to flicker stimulation were examined by DVA in both eyes of 37 hypertensive and 41 healthy control subjects...

Urogenital tuberculosis does not have pathognomonic symptoms, so diagnostic errors are quite common. This systematic review of literature was conducted to identify the causes and estimate the incidence of erroneous diagnoses. We critically evaluated some articles in which the authors describe observations of urogenital tuberculosis as rare and unusual because they never encountered this disease, but in fact that were typical manifestations of genitourinary tuberculosis. The authors analyzed and illustrated the features of urinary tuberculosis in patients with pulmonary tuberculosis, differential diagnosis of urogenital tuberculosis and kidney cancer and male genitourinary organs, described errors in the diagnosis of urethral, testicular, penile, prostatic and epididymal tuberculosis...

Endothelium-derived endothelin (ET)-1 has been implicated in the development of hypertension and end-organ damage, but its exact role remains unclear. We have shown that tamoxifen-inducible endothelium-restricted human ET-1 overexpressing (ieET-1) mice exhibited blood pressure rise after a 3-week induction in an ET type A (ETA) receptor-dependent manner, in absence of vascular and renal injury. It is unknown whether long-term ET-1 overexpression results in sustained blood pressure elevation and vascular and renal injury...
