Opinions about the following aspects were explored by means of service-specific questionnaires: Results of the survey show a high level of satisfaction with the services provided, i. However, and in agreement with other reports, this high level of satisfaction does not necessarily reflect an absence of problems, i.
Continuation of this kind of surveys in our setting leads not only to the identification of problems, but also to the evaluation of the impact that resulting measures may have on the patient's satisfaction. We reviewed all liver biopsy reports from January to December From patient records we obtained the following data: We correlated clinical, biochemical and histological data.
From biopsies reviewed we obtained 16 cases of NASH. We found a 7: Median age was 30 years and six patients were obese. Eleven patients had concomitant disease diabetes in seven and nine were using drugs. All had been studied for biochemical abnormalities and were asymptomatic.
Ten patients had hepatomegaly and six splenomegaly. All had steatosis, inflammatory infiltrate, necrosis, fibrosis and Mallory bodies at different stages. One case had cirrhosis on initial biopsy and two developed cirrhosis on follow-up one and eight years later. We did not find any correlation between clinical, biochemical or imaging characteristics and histological findings. When we compared these findings between obese and non obese patients and primary and secondary NASH we did not find any differences between groups. NASH is infrequent in our institution.
The underlying pathogenesis seems to be multifactorial. There is no biochemical-histological correlation. Cirrhosis can develop in some cases.

Biosafety evaluation of the DNA extraction protocol for Mycobacterium tuberculosis complex species, as implemented at the Instituto Nacional de Salud, Colombia. Manipulating Mycobacterium tuberculosis clinical specimens and cultures represents a risk factor for laboratory personnel. One of the processes that requires high concentrations of microorganisms is DNA extraction for molecular procedures. Pulmonary tuberculosis cases have occurred among professionals in charge of molecular procedures that require manipulation of massive quantities of microorganisms.
This has prompted research studies on biosafety aspects of extraction protocols; however, as yet, no consensus has been reached regarding risks associated with the process. The biosafety was evaluated for the DNA extraction protocol of van Soolingen, et al. Eight hundred eighty cultures were grown from M. Molecular identifications of positive cultures used a PCR isolation of a fragment of the heat shock protein PRA-hsp65 and examination of its restriction enzyme profile spoligotyping.
Growth was seen in one culture with one of the procedures used. The molecular characterization did not correspond to the initially analyzed isolate, and therefore was deduced to be the product of a cross-contamination. The DNA extraction protocol, as described by van Soolingen, et al. We present a review of our efforts to introduce astronomy as scientific career in Peru, showing how our astronomy outreach programs have been one of the most important keys to reach our national astronomical scientific goals, remarking the crucial role that the celebration of the IYA must play, in order to promote PhD programmes in astronomy in developing countries.
We also show how important was to rediscover our ancient astronomical cultural past of Incas in order to promote the construction of a Astronomical Center located near Cusco city over meters above sea level, which includes a tourist-educational observatory, a scientific optical observatory and a solar radio observatory.

Malignant tumors of the small bowel are uncommon and include multiple histologic strains, which helps explain the existing limited understanding of them.
The aim of this study was to evaluate surgically treated small bowel tumors and to determine the clinical and pathological characteristics that can have an impact on patient outcome. A retrospective, observational, and descriptive study was carried out.

Thirty-eight small bowel tumor patients were found that had been operated on within the time frame studied. Fifteen of them were women The histologic distribution was 13 adenocarcinomas There was an increase in the incidence of sarcomas and adenocarcinomas, whereas lymphomas and neuroendocrine tumors were evenly distributed. An increase in small bowel tumor incidence in the last few years was observed and adenocarcinoma was the most frequent tumor in the study population.
It is important to have a high degree of suspicion for this disease when patients present with symptoms such as gastrointestinal bleeding, bowel obstruction, anemia, and weight loss, because early diagnosis is essential for guaranteeing favorable outcome. The hepatopulmonary syndrome HPS and portopulmonary hypertension PPHN are distinct pulmonary vascular complications of portal hypertension PHT and are associated with increased morbidity and mortality. For analysis, they were divided into a first group of patients with liver cirrhosis and a second group with extrahepatic portal vein obstruction.
Of 22 patients with HPT They most often dyspnea, asthenia, edema, malnutrition, ascites, hypersplenism and gastrointestinal bleeding from esophageal varices was found.
Also, they had elevated ALT values, alkaline phosphatase and serum albumin values decreased. In children with pulmonary hypertension, pulmonary vascular complications are rare. In the evaluation of these patients pulse oximetry should be included to detect hypoxemia and ubsequently a Doppler echocardiography and contrast echocardiography necessary. Dueto the finding of systolic pulmonary hypertension it is necessary to perform right heart catheterization. To determine the clinical and histological characteristics and prognostic factors of cervical cancer CC in young Peruvian patients.
The main histological types were: The average tumor size was 4. Overall 5-year survival was Elevated creatinine, anemia, tumor size, parametrial involvement and hydronephrosis were factors that affected survival. No significant relation was found between histological type and survival. The presence of anemia adjusted hazard ratio [aHR]: Cervical cancer in young Peruvians is diagnosed in advanced stages.
Overall survival in each stage is similar to the reported in older patients. The importance of conventional prognosis- related factors was confirmed.

Anemia was an important independent prognostic factor requiring further investigations. Instituto Geografico Nacional of Spain. Prehepatic portal hypertension in children can be asymptomatic for many years. Once diagnosed, the therapeutic measures pharmacologic, endoscopic, and surgical are conditioned by the specific characteristics of each patient.
In Mexico, there are no recorded data on the incidence of the disease and patient characteristics. A cross-sectional, retrolective, descriptive, and observational study was conducted in which all the medical records of the patients with portal hypertension diagnosis were reviewed. The primary reason for medical consultation was upper digestive tract bleeding with anemia Splenoportography was carried out on 17 of the 32 patients.
A total of Initial endoscopy revealed esophageal varices in The varices were ligated in 8 cases, sclerotherapy for esophageal varices was carried out in 5 cases The primary cause of the disease was cavernomatous degeneration of the portal vein; it was predominant in males and the first symptom was variceal bleeding. First steps of vulagarization of science in the late ninetheen century: Since the founding of the Observatorio Astronomico Nacional de Chapultepec in during the presidential term of General Porfirio Diaz, begins the publication of the Yearbook of the Observatorio Astronomico Nacional de Chapultepec from now on OAN in a period when the positivist paradigm based on will boost science as a means of national progress.
The importance of conferences to which he attended started the sharing printed information relating to subjects such as astronomy, meteorology, cartography and geography. The Yearbook was intended to publish two or three months before the beginning of each year and according to the editor would serve to popularize science, making its contents available to anyone with basic knowledge of geometry or for amateur astronomers. I find that the yearbook was the publication that was released to the observatory in the country and abroad, but was sent to distant places where no one speaks or reads Spanish.
The access to the Bulletin was the Mexican intellectual elite grouped into societies, astronomical or meteorological observatories and another wealthy person individually. The same happened abroad. The collection of data from reports to the Secretaria de Fomento, that was the government agency that funds money destined to different scientific institutions founded during this period were published in the Yearbook, the oficios that sent the OAN over a hundred sites in the world.
Far away from populated areas, ELL site acts as a remote site, but it is also responding to discrete events as snow melting, summer cattle breeding on pastures and trekking frequentation. In the long term, these measurements show the mountain ecosystems contribution and geomorphologic influence on the CO2 budget of the air masses crossing a mountain range.
