Diverticulosis is defined as the presence of diverticula in the intestine, when these diverticula become inflamed diverticulitis occurs, but this complication happens in less than 5% of these patients. Surgical treatment is indicated in complicated diverticulitis cases. Traditionally, the Hartmann procedure is carried out in patients with Hinchey III and IV acute diverticulitis. Currently, individualized surgical procedures are indicated in patients with non-fecal purulent peritonitis with laparoscopic peritoneal lavage as an optional choice. Objective: To report the results of laparoscopic peritoneal lavage in four patients with Hinchey III acute diverticulitis performed at a private clinic. Methods: Case series for which a review of patient clinical files was done. Results: No post-operative complications or mortality was found. Conclusions: based on authors judge, laparoscopic peritoneal lavage leads to an adequate post-operative evolution resulting in better quality of life. [ABSTRACT FROM AUTHOR]

Background: Melanoma is one of the main neoplasms with metastasis to the digestive system and needs a high index of diagnostic suspicion. Case report: A 64-year-old male patient with abdominal pain, vomiting and liquid stools. The admission diagnosis was gastrointestinal bleeding, ruled out by endoscopy and colonoscopy. Fifteen days after hospitalization, he presented symptoms of intestinal obstruction, confirmed by tomography, and incidentally, a tumor in the right hemithorax. The surgery finding was a polypoid mass in the ileum. Extended anamnesis reveals a history of cutaneous melanoma on the face. The immunohistochemistry demonstrated the melanocytic lineage of the lesion. The final diagnosis was intestinal obstruction due to intestinal polypoid metastatic melanoma. Conclusion: Intestinal obstruction due to melanoma metastasis is a diagnostic challenge due to the nonspecific clinical and radiologic presentation. The suspicion of the etiology should start from the anamnesis and confirm the tumor cellular lineage trough histopatology. [ABSTRACT FROM AUTHOR]

Introduction: anemia is a worldwide public health problem. There are few studies that explore the knowledge that primary care physicians have about the diagnostic process in children and adolescents with anemia. Objective: to determine the level of clinical aptitude that the first-contact physician has regarding the diagnostic process of the pediatric patient in whom anemia is suspected. Material and methods: cross-sectional study. A seven-question questionnaire (developed by Delphi consensus) was applied to evaluate theoretical and practical concepts about the diagnostic process when anemia is suspected. The questionnaire was distributed electronically to general practitioners, family doctors, and pediatricians in the metropolitan area of Monterrey, Nuevo León, Mexico. Results: 154 doctors were included, 68 were pediatricians (44.2%), 51 family doctors (33.1%) and 35 general practitioners (22.7%). Of the total, 53.9% (n = 83) worked in a public institution. The median of correct answers was 5 (IQR 4-6). The highest proportion of correct answers was in anemia etiology (62.3%), followed by laboratory studies (48.1%), and initial clinical approach (14.9%). Compared to the other two groups, pediatricians obtained a higher percentage of correct answers. Conclusions: first-contact physicians have deficiencies in their clinical aptitude for the approach to pediatric patients with suspected anemia. [ABSTRACT FROM AUTHOR]

Pediatric brachial plexus block has become a good alternative for upper extremity surgical procedures, especially since the advent of ultrasonography. The main aim of the study was to evaluate the effectiveness of the blockade with the costoclavicular approach in the pediatric population, and compare the sonoanatomy of the costoclavicular window with the coracoid one, and determinate if the position of the arm has an impact on the ultrasound image. A total of eight patients with upper limb fractures were evaluated. Of the eight patients, five were male (62.5%), three female (37.5%) with a mean age of 8.8 years. Ultrasonographic screening was performed comparing the sonoanatomy of the costoclavicular and coracoid approaches, better observing the brachial plexus cords and vascular structures with the costoclavicular approach. With the arm abducted 90 and 110o, a better visualization of the neurovascular structures and an improvement in the quality of the block was obtained. The ropivacaine dose was 1.5 mg/kg between 0.3-0.5%, with an average motor block time of 6.7 hours, and an average sensory block of 11.25 hours. There were not complications. In conclusion, the brachial plexus block via the costoclavicular approach in the pediatric population is a safe technique. [ABSTRACT FROM AUTHOR]

This research work was based on the integration of datamart with datawarehouse as its possible implementation since in our documentation evidence was found that the integration of the database in this case the datamart must be carried out in a correct way and here we have a greater integration of data for users who use it and it has been difficult to lose information since a datawarehouse is a repository of information, nowadays there are many programs that allow us to synchronize information from a datamart with the datawarehouse in a fast and simple. Although not all the databases provide security when performing data integration for this reason, several factors must be taken into account. To carry out this scientific article, some methodological methods were carried out, such as the following: Historical-logical, Analysis-Synthesis between others have already helped a lot in the search for information and at the same time have a better understanding of the subject of how datamart integrates with datawarehouse [ABSTRACT FROM AUTHOR]

The objective of this article is to analyse the consumption patterns incorporating the demographic effects in Mexico using the ENIGH-2018. The main results show that the consumption patterns for different goods i can be specified as a function of total expenditure, of the demographic variables and the control variables such as economic and social characteristics. The demographic characteristics such as the number of members and children in the household affects the expenditure patterns of the household. For example, the proportion of expenditure in food and house with respect to total expenditure of the households is larger in households without children than with children and the proportion of expenditure with respect to total expenditure is larger in education and amusement in households with children than without children. Furthermore, the number of members and children modified the expenditure in food, education, housing, transport and clothes and the Engel expenditure elasticities indicate that food and clothes are necessary goods and education and amusement are, in general, luxury goods.

Mercury, an element widely used by man occurs in different chemical states, one of them is elemental mercury used in ancient medical practice. It is still used by some people who maintain the belief of its effectiveness for abdominal discomfort. We present the case of a 46-year-old woman, who was urgently transferred to a National Hospital due to a constant abdominal discomfort, a hysterosalpingectomy and appendectomy were performed. She was diagnosed with ovarian malignancy and incidentally, elemental mercury retention was found within the appendix. The history showed that the patient had ingested this substance to calm the abdominal discomfort she was presenting before her diagnosis of cancer. [ABSTRACT FROM AUTHOR]

Introduction: Introduction: in Mexico the main problem in public health is obesity and other diseases that are associated whit this condition, including oral health. Objective: to evaluate the effect of metformin treatment in patients with class I obese on the activity of metalloproteinases present in periodontium with chronic periodontitis. Methods: a clinical study was conducted in 68 patients with class I obesity and periodontal disease. They were divided into 4 groups. 2 of them, in addition to the periodontal treatment, were administered metformin 850 mg per day for six weeks; 2 samples were taken per patient of periodontal tissue before and after each treatment, body mass index, plaque index and inflammation were measured. Acrylamide gel zymography was used to measure the activity of metalloproteinases in the sample of tissue collected. The data obtained were analyzed by descriptive statistics, student t for related samples and one-way ANOVA was performed considering p < 0.01 as statistically significant. Results: in the group of patients who were administered metformin at the end of the treatment, there was a decrease in the body mass index, the degree of inflammation and lower metalloproteinase activity, compared with the control group (65% vs 25%; < 0.01). Conclusions: treatment with metformin in patients with obesity class I and periodontal disease decreases BMI, improves the symptoms of chronic periodontitis and decreases the activity of metalloproteinases 1, 3, 8, V present in periodontium of these patients.

Introduction- Job Shop (JS) production systems are characterized by different route process of the Jobs to be processed. A generalization of this type of systems is the Flexible Job Shop (FJS), in which there is more than one machine per station to perform some of the operations. Objective: The objective of this project was to propose a mixed integer linear programming model to program FJS systems in order to minimize the number of tardy jobs. Methodology: The model was developed using an approach based on sequence-position variables. This approach uses binary variables to decide whether a given operation is assigned to a position in the processing sequence of the assigned machine. To validate the performance of the model data from a small company with an FJS type production system, that develops its operations in an environment to order (MTO), was used. For this reason, the most important performance indicators for the company are those associated with the service level. Results: The results show a reasonable performance in terms of the objective pursued. The optimal production schedule was found in less than 3600 seconds in instances of less than 14 production orders. In larger instances, it obtained feasible solutions within the defined time limit. Conclusions: The model allows defining production schedules in systems in which the fulfillment of due dates is of vital importance. The results have allowed the company to improve its performance and reduce the costs associated with non-compliance of customer's due dates. Future research can be developed to find more efficient solution methods in terms of computational times to obtain solutions of larger instances. [ABSTRACT FROM AUTHOR]

The trend of the indexes of the nonlinear dynamics in an environmental pre-contingency by particles PM10 in the Metropolitan Area of Mexico Valley was found. The tools of chaos theory were applied to determine the dynamic behavior coincidences and the study period from December 15 to January 7 was selected. The indexes of nonlinear dynamics were calculated to evaluate the changes in the dynamic behavior and the attractors in the phase space were plotted. The results obtained in terms of persistence, divergence and autocorrelation vary depending on the concentration of PM10. The Hurst exponent allowed finding the best concordance with PM10 and it was observed that when it exceeds the value of 0.3 the probability of reaching a pre-contingency event increases.

The purpose of this article is to assess the working conditions of female teachers of the instructionist official education system in the department of Antioquia, at the beginning of the twentieth century. This reflection is based on the information gathered from official documents, reports, and some opinion pieces, related to the national education system between 1903 and 1930; a context in which, although women were majority in the educative labor, they had to face a hard struggle to gain participation in pedagogical discussions conceptually addressed by male teachers. By 1903, the 75% of the teacher profession in Antioquia was constituted by women. However, in the local scenarios where methodological, philosophical, and teaching issues related to the instructionist system were discussed, resistance to female participation appeared from different social sectors. This article shows how, despite the fact that women from Antioquia worked actively for the education of children in schools, this was considered irrelevant in allowing their participation in reformist debates.

At the beginning of the 20th Century, in Colombia an instructionist reform was in operation, aiming to make a social transformation of the country. Then, the time of education to help the great national reconstruction endeavor had arrived and such news was being announced with the drumbeats of the official reform of 1903. In such sense, teachers were being urgently called by Dirección de Instrucción Pública to occupy a place in the frontline of this army of saviors. [ABSTRACT FROM AUTHOR]
