The impact of psychopharmacology on contemporary clinical psychiatry.

2014

Clinical psychiatric evaluations of patients have changed dramatically in recent decades. Both initial assessments and follow-up visits have become brief and superficial, focused on searching for categorical diagnostic criteria from checklists, with limited inquiry into patient-reported symptomatic status and tolerability of treatments. The virtually exclusive therapeutic task has become selecting a plausible psychotropic, usually based on expert consensus guidelines. These guidelines and practice patterns rest mainly on published monotherapy trials that may or may not be applicable to particular patients but are having a profound impact, not only on modern psychiatric practice but also on…

Histamine and spontaneously released mast cell granules affect the cell growth of human hepatocellular carcinoma cells

2007

The role of mast cells in tumor growth is still controversial. In this study we analyzed the effects of both histamine and pre-formed mediators spontaneously released by mast cells on the growth of two human hepatocellular carcinoma cell lines, HA22T/VGH and HuH-6, with different characteristics of differentiation, biological behavior and genetic defects. We showed that total mast cell releasate, exocytosed granules (granule remnants) and histamine reduced cell viability and proliferation in HuH-6 cells. In contrast, in HA22T/VGH cells granule remnants and histamine induced a weak but significant increase in cell growth. We showed that both cell lines expressed histamine receptors H(1) and …

A life-threatening complication of parenteral nutrition: how to prevent cardiac tamponade?

2014

Complications caused by incorrect central venous insertion are numerous. Cardiac tamponade is a rare, but well-documented complication that is often lethal. We present the case of a patient with cardiac tamponade caused by incorrect tip position and infusion of hyperosmolar fluids such as for parenteral nutrition.

Cancer Patients Requiring Interruption of Long-Term Anticoagulant Therapy: The Use of Fixed Sub-Therapeutic Doses of Low-Molecular Weight Heparin

2011

Abstract Abstract 1244 Introduction. We tested the efficacy and safety of fixed doses of Low-Molecular Weight Heparin (LMWH) in cancer patients requiring interruption of Vitamin-k Antagonist (VKA) because of invasive procedures (defined as major and non major surgery) or chemotherapy inducing platelets depletion. Methodology. Cancer patients were defined to be at high (atrial fibrillation [AF] with previous stroke, prosthetic mitralic valves and venous thromboembolism [VTE] lasting < 3months) or low risk of thrombosis (AF without previous stroke, VTE lasted > 3 months, and prosthetic aortic valves). They discontinued VKA 5 + 1days before surgery or chemotherapy; in those at low-risk f…

Anti-androgens for the treatment of hirsutism.

2002

Many alternatives exist for treating hirsutism. Based on an analysis of scientific literature and on the experiences of the author, the most common anti-androgen agents are discussed in this review. Androgen receptor blockers (cyproterone acetate, flutamide and spironolactone), 5 alpha-reductase inhibitors (finasteride) and androgen-suppressing agents (gonadotrophin-releasing hormone [GnRH] agonists, oestroprogestins, corticosteroids and insulin-sensitising agents) are evaluated and compared. The importance of diagnosis in choosing the most appropriate anti-androgen treatment is also discussed.

Management of Coronary Artery Perforation

2020

Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI), however if recognized and managed promptly, its adverse consequences can be minimized. Risk factors for CAP include the use of advanced PCI technique (such as atherectomy and chronic total occlusion interventions) and treatment of severely calcified lesions. There are 3 major types of CAP depending on location: (a) large vessel perforation, (b) distal vessel perforation, and (c) collateral perforation. Large vessel perforation is usually treated with implantation of a covered stent, whereas distal and collateral vessel perforations are usually treated with c…

Body composition and muscle performance during menopause and hormone replacement therapy.

2003

Menopausal transition is characterized by ovarian failure and its consequent decrease in female sex steroid production. Earlier studies suggest that an increase and redistribution of body fat during menopause predispose women to cardiovascular disease and metabolic syndrome. In addition, peri- and post-menopausal women seem to have less lean body mass (LBM) compared with pre-menopausal women. Accordingly, a changing ovarian hormonal status may accelerate the loss of muscle mass and result in decreased muscle performance and functional capacity. Hormone replacement therapy (HRT) has been used to treat menopausal symptoms and as a primary prevention therapy in chronic conditions. Inconsistent…

Pathophysiology of polymorphonuclear leukocyte in arterial hypertension

2009

This review shows how polymorphonuclear leukocytes (PMNs) play a pivotal role in the development of the organ injury that is associated with arterial hypertension. Elevated white blood cell count and higher levels of PMNs activation are risk factors for arterial hypertension and cardiovascular disease. Spontaneously activated PMNs release proinflammatory factors and reactive oxygen species, which have negative effects on vascular tone and on their adhesion to the endothelium. The oxidative stress in hypertensive PMNs is revealed by increased NADPH-oxidase production and lipid peroxidation and by decreased cytosolic and mitochondrial superoxide dismutase concentrations. The overexpression of…
