BACKGROUND: Remote ischemic preconditioning (RIPC) represents an attractive therapy for myocardial protection, particularly when ischemic events can be anticipated. Although several hypothetic mechanisms have been proposed, no definite molecular pathways have been elucidated. OBJECTIVE: We evaluated the effect of brachial circulation cuff occlusion on myocardial ischemic tolerance, necrosis, and nitric oxide (NO) in patients with ischemic heart disease undergoing elective percutaneous coronary interventions (PCI)...

El uso de la nutrición parenteral domiciliaria (NPD) en pacientes que no pueden alcanzar sus requerimientos nutricionales por la vía enteral está aumentando en los últimos años, permitiendo la normalización del estilo de vida de los pacientes. Entre las patologías que más frecuentemente precisan de la NPD en España destacan la neoplasia y la isquemia mesentérica. Sin embargo, la NPD constituye uno de los pilares básicos del tratamiento de enfermedades mucho menos frecuentes como es el caso de la esclerosis peritoneal encapsulante...

Acute colonic volvulus accounts for 10% of all intestinal obstructions being the transverse colon volvulus an exceptional localization (2-4%). Late diagnosis is made as there are no pathognomonic clinical or radiological findings for this pathology. We present the case of an 81 year-old male with acute transverse colon volvulus that involved the gastric antrum causing irreversible ischemia. Subtotal gastrectomy, subtotal colectomy and reconstruction with Y en Roux gastrojejunostomy and ileosigmoid anastomosis was performed given the good overall status of the patient...

The liver has come a long way since it was considered only a metabolic organ attached to the gastrointestinal tract. The simultaneous ascension of immunology and intravital microscopy evidenced the liver as a central axis in the immune system, controlling immune responses to local and systemic agents as well as disease tolerance. The multiple hepatic cell populations are organized in a vascular environment that promotes intimate cellular interactions, including initiation of innate and adaptive immune responses, rapid leukocyte recruitment, pathogen clearance and production of a variety of immune mediators...

INTRODUCTION: Information regarding hospital arrival times after acute ischaemic stroke (AIS) has mainly been gathered from countries with specialised stroke units. Little data from emerging nations is available. We aim to identify factors associated with achieving hospital arrival times of less than 1, 3, and 6 hours, and analyse how arrival times are related to functional outcomes after AIS. METHODS: We analysed data from patients with AIS included in the PREMIER study (Primer Registro Mexicano de Isquemia Cerebral) which defined time from symptom onset to hospital arrival...

INTRODUCTION: Systemic sclerosis (SSc) is a systemic disease, characterized by fibrosis and vasculopathy, with variable internal organ involvement. Skin is very often involved, namely digital ulcers (DU), seldom treatment resistant, responsible for important functional limitation. The DU can evolve from sclerodactily with superficial ulcers, isquemic lesions, deep necrosis, gangrene, loss of tissue, and consequently, to finger amputation. METHODS: The authors describe the case of a 36 year old female patient, with SSc diagnosed 6 years previously, with skin, lung and gut manifestations...

INTRODUCTION: The intestine is a highly sensitive tissue to ischemia-reperfusion (IR) injury that will early respond increasing its permeability. Later this response is translated in morphologic and histological changes that reveal the degree of damage. The heterotopic intestinal transplantation model in rats allows to evaluate the evolution of intestinal tissue injury after ischemia-reperfusion without affecting the long survival rate. OBJECTIVE: The aim of this paper is to establish a relationship between the ischemic reperfusion injury with the long-term survival METHODS: Ten intestinal transplants were analyzed in adult, Wistar, inbred, male rats...

OBJECTIVE: The ulcers, infections and isquemia of the foot are the main causes of hospitalisation of the diabetic patient and, very frequently, they are reason for the amputation of the limb. The objective of this investigation consists of evaluating the results of a multidisciplinary clinical pathway designed by the set of specialists of different departments from our hospital, as well as of the associated personnel of infirmary, implied in the management of this pathology. PATIENTS AND METHODS: We have analysed the evolution of a series of clinical and socio-economic indicators comparing, in the patients admitted with diagnose of complicated diabetic foot, the previous period to the implantation of the clinical pathway years 1998, 1999 and 2000) with the later period to this implantation (years 2001 and 2002)...

Two 38 and 53-year old male patients with unstable angina, whose hemodynamic study showed an isolated stenosis of the left coronary artery ostium, were submitted to a surgical angioplasty of the left main coronary artery (LMCA) with saphenous vein patch. At the end of the operation, the patients presented intermitent myocardial isquemia. One of them led to abrupt cardiogenic shock which reversed completely. The postoperative hemodynamic study demonstrated excellent left main coronary artery patency and normal left ventricular of LMCA has been proposed as an alternative technique to the treatment of ostial lesions, the surgical team should be prepared to face severe operative morbidity...

For patients with acute myocardial infarction intravenous thrombolytic therapy has become the standard care in restoring patency of the infarct-related coronary artery. Nearly 200.000 patients have been involved in thrombolytic trials over the last decade. A significant decreases in short-term mortality has been shown for those patients who are eligible for treatment with thrombolytics. However, in approximately 20% of patients patency is not achieved, a high-grade residual coronary stenosis is left, reocclusion of the open vessel, an increased incidence of recurrent ischemia and serious bleeding complications can occur with this therapeutic modality, resulting in increased morbidity and mortality...
