[Medical-surgical experience of intestinal intussusception. Experience of a university institution].
Management of intestinal intussusception in children has evolved from exclusively surgical treatments to nonoperative reduction under fluoroscopic monitoring. ⋯ Nonsurgical reduction is safe and effective as the initial treatment of uncomplicated intussusception in children.

[Delirium in patients of an intermediate care unit: prospective study].
Delirium or acute confusional state is defined as an acute disturbance of consciousness and attention. Its prevalence among hospitalized patients fluctuates between 25 and 60%. ⋯ The prevalence of delirium found in this study is similar to that reported elsewhere, except for the high proportion of patients whose delirium started after admission.

Review[Prevention and treatment of obesity since childhood: strategy to decrease the non transmissible chronic diseases in adult].
The prevalence of obesity among children and teenagers is increasing by 1.5% per year, probably due to a higher consumption of highly caloric foods and to physical inactivity. Hypercholesterolemia, increased insulin levels and high blood pressure of childhood obesity, precede atherosclerosis, coronary artery disease, diabetes and hypertension in adulthood. ⋯ They aim at a change in dietary habits and increasing physical activity. A well balanced healthy diet and a decrease in physical inactivity time will result in a successful treatment approach for obesity.

Some authors have proposed that the use of regional anesthesia has advantages over general anesthesia. ⋯ Endarterectomy under regional anesthesia is less invasive, has excellent results and is well accepted by patients.

Review[Inactivation of tumor suppressor genes in uterine cervix carcinogenesis].
The importance of inactivation of tumor suppressor genes in the development/progression of carcinomas of the uterine cervix is reviewed. It is well known that HPV-related oncogenes are strongly linked to cervical cancer. However, fewer studies have explored the occurrence of inactivation of tumor suppressor genes in this neoplasia. ⋯ Deletions are detected even in precursor lesions (cervical intraepithelial neoplasia, CIN). Some deletions have been correlated with prognostic parameters, such as stage, depth of invasion, and vascular space involvement. It is concluded that cervical carcinogenesis, like in other tumors, is a multistep process, characterized by the accumulation of events including activation of oncogenes, as well as inactivation of tumor suppressor genes.
