Randomized clinical trial comparing inflammatory and angiogenic response after open versus laparoscopic curative resection for colonic cancer.

Background: Several studies have suggested that laparoscopy might confer an oncological advantage in patients undergoing surgery for colonic cancer. A decreased inflammatory and angiogenic response has been proposed. This study compared the local and systemic inflammatory and angiogenic responses after open and laparoscopic surgery for colonic cancer.

Epidemiology of adenocarcinoma of the esophagus, gastric cardia, and upper gastric third.

The incidence of adenocarcinoma of the esophagus and esophagogastric junction (gastric cardia) has risen rapidly over the past three decades in the United States and northern Europe. This increase had been most dramatic among White males. The majority of these cancers arise from Barrett's esophagus.

[Bone mass loss after sleeve gastrectomy: a prospective comparative study with gastric bypass].

Introduction: Bariatric surgery is the most effective option for the treatment of patients with a high risk of complications due to their obesity. However, it brings about a series of changes in calcium and vitamin D metabolism and an increase in resorption which lead to a loss of bone mass.

Aim: The objective of this study is to compare sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) as regards loss of bone mass using bone densitometry and bone remodelling markers.

[Cold or hot sitz baths in the emergency treatment of acute anal pain due to anorectal disease? Results of a randomised clinical trial].

Introduction: The popular belief advocates the use of sitz (sitting) baths with cold water for the treatment of acute anal pain, but clinical practice guides recommend the use of hot water for its known effect on the at-rest anal pressure.

Aim: The objective of the study was to examine the analgesic effect on the quality of life, manometer data and clinical progress, of the two temperatures in sitz baths in patients with anal pain.

Material And Methods: A randomised clinical trial on patients with acute anal pain due to haemorrhoids or anal fissures, divided into Group 1: Sitz baths with water at a temperature of less than 15 degrees C, and Group 2: Baths with a water temperature above 30 degrees C.

[Multimodal (fast-track) rehabilitation in elective colorectal surgery: evaluation of the learning curve with 300 patients].

Introduction: The aim of this paper is to assess the learning curve on compliance to the application of a multimodal rehabilitation program (MMRP) protocol and patient recovery after elective colorectal surgery.

Material And Methods: A comparative prospective study of 3 consecutive cohorts of 100 patients (P1, P2 and P3) who had colonic or rectal surgery. The same MMRP protocol was applied in all cases.

Dynamics of NO motion in solid-state [Co(tetraphenylporphinato)(NO)].

The temperature dependence of the crystalline phase of (nitrosyl)(tetraphenylporphinato)cobalt(II), [Co(TPP)(NO)], has been explored over the temperature range of 100-250 K by X-ray diffraction experiments. The crystalline complex is found in the tetragonal crystal system at higher temperatures and in the triclinic crystal system at lower temperatures. In the tetragonal system, the axial ligand is strongly disordered, with the molecule having crystallographically required 4/m symmetry, leading to eight distinct positions of the single nitrosyl oxygen atom.

[Incidence of iatrogenic perforation during colonoscopy and their treatment in a university hospital].

Introduction: Colon perforation is a fairly uncommon, but serious, complication during endoscopy of the lower gastrointestinal tract. Treatment is controversial, although surgery is used in the majority of cases. The aims of this study were to determine the incidence of perforations due to colonoscopy in our hospital and to find out the results of the treatment options used.

[Prevalence of fecal incontinence and its relationship with bowel habit in patients attended in primary care].

Background And Objectives: Fecal incontinence is a high prevalence disease in general population. The diagnosis of alterations in bowel habit could be of interest for the management of this clinical disorder. The aim of the study was to study the relationship between fecal incontinence prevalence and alteration of bowel habit in patients of a metropolitan area of Barcelona.

Prevalence of faecal incontinence and analysis of its impact on quality of life and mental health.

Aim: Faecal incontinence is a significant healthcare problem, with an estimated prevalence of up to 5% of the general population. Little is known about its prevalence among patients attending primary care.

Method: A cross-sectional multicentre study was undertaken.

Variation in blood pressure is associated with white matter microstructure but not cognition in African Americans.

Although hypertension is a major risk factor for cerebrovascular disease (CVD) and is highly prevalent in African Americans, little is known about how blood pressure (BP) affects brain-behavior relationships in this population. In predominantly Caucasian populations, high BP is associated with alterations in frontal-subcortical white matter and in executive functioning aspects of cognition. We investigated associations among BP, brain structure, and neuropsychological functioning in 52 middle-older-age African Americans without diagnosed history of CVD.

[Methodological quality of articles on therapeutic procedures published in Cirugía Española. Evaluation of the period 2005-2008].

Aim: To determine methodological quality of therapy articles published in Cirugía Española and to study its association with the publication year, the centre of origin and subjects.

Material And Methods: A literature study which included all therapy articles published between 2005 and 2008. All kinds of clinical designs were considered, excluding editorials, review articles, letters to editor and experimental studies.

Outpatient treatment of patients with uncomplicated acute diverticulitis.

Aim: Evidence supporting outpatient treatment with oral antibiotics in patients with uncomplicated diverticulitis is limited. Our aim was to evaluate the safety and efficacy of an ambulatory treatment protocol in patients with uncomplicated acute diverticulitis.

Method: All patients diagnosed with uncomplicated diverticulitis based on abdominal computed tomography findings from June 2003 to December 2008 were considered for outpatient treatment.

Postoperative intra-abdominal infection increases angiogenesis and tumor recurrence after surgical excision of colon cancer in mice.

Background: Recent reports have suggested that anastomotic leakage is associated with greater rates of tumor recurrence and cancer-specific mortality after surgery for colorectal cancer. The impact of postoperative intra-abdominal infection on long-term oncologic results, however, is still controversial, and no direct causal relationship has been found between both processes. Our aim was to investigate the influence of postoperative intraabdominal infection on angiogenesis and tumor growth in an animal model of colon cancer.

Resection of the uncinate process of the pancreas due to a ganglioneuroma.

A 33-year-old woman who presented with epigastric discomfort and diarrhea underwent an abdominal ultrasound (US). This investigation and subsequent contrast-enhanced computed tomography, magnetic resonance imaging and endoscopic US with fine needle aspiration (FNA) revealed a 40 mm well-circumscribed mass in the uncinate process of the pancreas. Findings were suggestive of a mucinous or solid-cystic pseudopapillary tumor of the pancreas, although other lesions such as a non-functioning neuroendocrine tumor could not be ruled out.

Hippocampal volume and declarative memory function in combat-related PTSD.

The proposition that declarative memory deficits are systematically related to smaller hippocampal volume was tested in a relatively large sample (n = 95) of U.S. military veterans with and without combat-related posttraumatic stress disorder.

[Endoanal ultrasound findings in patients with faecal incontinence using a scoring system].

Introduction: The main aim of the study was to apply a severity classification of sphincter lesions detected by endoanal ultrasound using Starck score in patients who suffered faecal incontinence.
