Pneumatosis cystoides intestinalis has an unknown etiology, although in a high percentage of patients it has been associated with obstructive pulmonary pathologies, connective tissue diseases, immunosuppression or gastrointestinal diseases. It is located more frequently in the colon and small intestine. It is diagnosed mainly through imaging tests (radiography or computed tomography). The treatment is conservative, performing surgical intervention if there is suspicion of intestinal necrosis; being difficult the differential diagnosis with a pneumoperitoneum by perforation of hollow viscera..

Background: Pneumatosis cystoides intestinalis is an infrequent condition, characterized by the formation of gaseous content cysts under the mucosa and intestinal serous. Clinical case: 84-year-old woman, with a history of rheumatoid arthritis under immunosuppressive treatment, operated 2 years ago by pneumoperitoneum, where she was diagnosed of jejunal diverticulosis and mesenteric emphysema, with diffuse abdominal pain of 2 days of evolution, without other symptoms. In abdominal radiography: pneumoperitoneum with elevation of right hemidiaphragm and distention of small intestine. Given the suspicion of perforation of the intestinal wall, surgical intervention was decided, in which the patient was diagnosed with pneumatosis cystoides intestinalis. Conclusion: Pneumatosis cystoides intestinalis has an unknown etiology, although in a high percentage of patients it has been associated with obstructive pulmonary pathologies, connective tissue diseases, immunosuppression or gastrointestinal diseases. It is located more frequently in the colon and small intestine. It is diagnosed mainly through imaging tests (radiography or computed tomography). The treatment is conservative, performing surgical intervention if there is suspicion of intestinal necrosis; being difficult the differential diagnosis with a pneumoperitoneum by perforation of hollow viscera.

Background: Prostate cancer is the most frequent neoplasm in Mexican men, the research literature contains few studies that address prostate cancer patients and quality of life in Mexico. Objective: The objective of the study was to validate the Functional Assessment Cancer therapy (FACT-P) scale. Methods: 201 males 49-90 years of age, at any clinical stage of prostate cancer, under treatment or follow-up participated. It is a non-experimental cross-sectional study. Patients were evaluated through the FACT-P jointly with the European Organization for Research and Treatment of Cancer Quality of Life and Hospital Anxiety and Depression Scale. Exploratory analysis examined the factorial structure, and confirmatory analysis to evaluate the adjustment of the exploratory model to the data. Results: A four-factor model that explained 64.65% of the variance, Cronbach's alpha 0.79, and correlations were statistically significant, Pearson's r of 0.146-0.716, p < 0.01 and p < 0.05. Analyses also distinguished metastatic patients from non-metastatic ones. The main indices of the confirmatory model were satisfactory for the adjustment of data and showed an estimate error close to zero. Conclusions: This Mexican version of FACT-P showed reliability and validity comparable to the original one.
