BACKGROUND AND AIMS Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain g...

Stent platforms are prone to fracture while incidental data are demonstrating a potential unfavorable outcome. Predisposing factors usually involve long lesions and tortuous vessels requiring more than one stent. This issue is magnified when it involves a periprocedural iatrogenic left internal mammary artery (LIMA) and subclavian artery dissection. In such complex clinical scenarios, the risk ...

A 68-year-old man underwent successful 3-vessel coronary artery bypass grafting (CABG): a left internal mammary artery (LIMA) was anastomosed end to side to a large diagonal branch of the left anterior descending coronary artery (LAD) and was then skipped to the distal LAD; and saphenous vein grafts (SVGs) were anastomosed to the circumflex and right coronary arteries. He returned to his cardio...

Methods From September 2010 up to May 2013 seven patients (four male and three female, aged 67,66 ± 10,85, pre op LVEF 47,85 ± 6,46) with a story of previous CABG (three patients using left internal mammary artery + saphenous vein; four patients using LIMA + radial artery; one patient using also the right internal mammary artery, number of by pass 2.85 ± 0.63) were admitted in our department fo...

The aim of this study was to describe the concentration of lead in umbilical cord blood (UCB) of neonates born from primiparous women who live in northern Lima. A cross sectional study was carried out at Cayetano Heredia National Hospital, from July 2011 to January 2012. 100 neonates born from primiparous women who lived in northern Lima in the previous 5 years or more were included. Umbilical ...

OBJECTIVE To analyze the trend of the monthly "caesarean section rate" (CSR) at the DISA V Lima-Ciudad Hospitals during the period 2001 - 2008. MATERIAL AND METHODS Ecological study that aim to analyze the monthly reports of all DISA V Lima-Ciudad Hospitals that attends childbirths, and by analyzing the trend of theirs monthly caesarean section ratio or monthly CSR (TCM = total caesarean birt...

Okadaic acid (OA) and dinophysistoxins (DTXs) are the main toxins responsible for diarrhetic shellfish poisoning (DSP) intoxications during harmful algal blooms (HABs). Although the genotoxic and cytotoxic responses to OA have been evaluated in vitro, the in vivo effects of these toxins have not yet been fully explored. The present work fills this gap by evaluating the in vivo effects of the ex...

BACKGROUND Tobacco smoking is an important public health concern worldwide leading to both chronic disease and early death. In Latin America, smoking prevalence is estimated at approximately 30% and prior studies suggest that the prevalence in Peru is 22% to 38%. We sought to determine the prevalence of daily smoking in a poor peri-urban community in Lima, Peru. METHODS We conducted a cross-s...

The only curative treatment for familial adenomatous polyposis (FAP) is prophylactic surgery and the two most popular options are total colectomy with ileorectal anastomosis and restorative proctocolectomy with ileal pouch-anal anastomosis. Today, ileal pouch-anal anastomosis has gained wider acceptance as a safer procedure, but ileorectal anastomosis still remains an option, especially for you...

Training of microvascular anastomosis techniques comprise the major part of surgical skills, necessary for revascularization surgeries. Training can be performed in several stages based on the experience of trainees. This should mainly start with various models of artificial materials that simulate tissues. In the next stage, trainee should practice microsurgical skill on a non-living tissue mo...
