Resistance to cephalosporins and quinolones in Escherichia coli isolated from irrigation water from the Rímac river in east Lima, Peru.

Objectives.: To evaluate the presence and sensitivity to antimicrobials of Escherichia coli strains isolated from 24 irrigation water samples from the Rimac river of East Lima, Peru.

Materials And Methods.

First report of CrpP prevalence in a South American country.

The presence of was established in 201 isolates from 9 Peruvian hospitals. The 76.6% (154/201) of the isolates presented the gene.

[Similarities and differences among patients with symptomatic atherosclerosis affecting several territories. The AIRVAG cohort (Integral Attention to Global VAscular Risk)].

Background And Objective: Even though atherosclerosis is a systemic disease, few prospective studies have evaluated in a thorough and systematic manner the whole vascular tree in patients with clinical damage of different territories.

Patients And Method: Prospective protocolized study of 269 consecutive patients younger than 70, attended because of symptomatic arteriosclerosis of any territory -53% coronary (CHD), 32% cerebrovascular (CVD), 15% peripheral (PVD)-. Patients underwent evaluation of risk factors and their control, systematic non-invasive study of the vascular tree (Doppler-ultrasound) and comparison between groups according to the index territory.

Paravertebral pseudoaneurysm thrombosed after percutaneous thrombin injection.

We present a case of a lumbar pseudoaneurysm in a 62-year-old patient with myelofibrosis (agnogenic myeloid metaplasia). The patient was submitted to two anesthetic infiltrations for lumbar pain and one biopsy of a suspected hematopoietic site. Subsequently, a 4.

Intraoperative venous balloon angioplasty during surgical thoracic outlet decompression in Paget-Schrötter syndrome.

The management of primary subclavian-axillary vein thrombosis is controversial. Indications and time of operative or endovascular intervention after successful thrombolysis remain unresolved. To improve the long-term functional outcomes in patients with primary subclavian-axillary vein thrombosis, early reestablishment of venous patency and prevention of recurrent thrombosis are required.

Abdominal aortic coarctation, renovascular, hypertension, and neurofibromatosis.

Abdominal aortic coarctation and renal artery stenosis associated with neurofibromatosis is an unusual cause of renovascular hypertension in children and young adults. Sustained hypertension despite pharmacological treatment carries significant end-organ deterioration, failure to thrive, and potentially lethal complications. Timely arterial reconstruction can render these children normotensive, allowing normal development and reducing long-term morbidity.

Conservative hemodynamic surgery for varicose veins.

Conservative hemodynamic surgery for varicose veins is a minimally invasive, nonablative technique that preserves the saphenous vein and helps avoid excision of varicosities. It represents a physiologic approach to the surgical treatment of varicose veins based on knowledge of the underlying venous pathophysiology gained through detailed duplex scanning. A change in venous hemodynamics is attained through fragmentation of the blood column by interruption of the refluxing saphenous trunks, closure of the origin of the refluxing varicose branches, and preservation of the communicating veins that drain the incompetent varicose veins into the deep venous system.
