    A novel surgical approach to slow-transit constipation: Report of two cases
    (LIPPINCOTT WILLIAMS & WILKINS, 2008) Pinedo, George; Leon, Francisca; Molina, Maria Elena; Soto, Gonzalo; Lopez, Francisco; Zuniga, Alvaro
    INTRODUCTION: Slow-transit constipation after proper diagnosis and extensive medical therapy may have a surgical solution. Total abdominal colectomy and ileorectal anastomosis, at our institution, is the surgical procedure of choice. Nonetheless, patients may reject this alternative because of morbidity.

    Adult Sensitivity Assessment in Interaction with 6-36 Months old Children: Design and Preliminary Analyses of Adult Sensitivity Scale
    (SOCIEDAD CHILENA PSICOLOGIA CLINICA, 2012) Pia Santelices, Maria; Carvacho, Claudia; Farkas, Chamarrita; Leon, Francisca; Galleguillos, Francisca; Himmel, Erika
    The adult sensitivity has been extensively studied in early childhood, for it is associated with a secure attachment bond with the child. Different sensitivity measuring instruments have been developed, primarily through observational methods. Most of them require extensive training or a complex experimental s setting. The aim of this study is to develop a new instrument to assess sensitivity in adult caretaker of children aged 6 to 36 months, with few requirements for its use. The context of measurement involved a brief free-play interaction, which is filmed and encoded. The instrument was applied to a sample of 99 significant adult-child dyads and the videos analyzed with a rubric for each sensitivity indicator. Results show that the instrument has adequate psychometric properties and can be used in different familiar, educational or institutional contexts.

    Gallbladder polyps
    (2006) Escalona, Alex; Leon, Francisca; Bellolio, Felipe; Pimentel, Fernando; Guajardo, Matias; Gennero, Ruben; Cruz, Juan Pablo; Viviani, Paola; Ibanez, Luis
    Background: Gallbladder polyps are becoming a common finding. The management of these polyps is complicated considering that they can bear malignant lesions. Aim: To analyze the ultrasonographic and histopatbologic findings of patients operated due to gallbladder polyps. Patients and methods: The records of patients with ultrasonograpbic diagnosis of gallbladder polyp and that underwent cholecystectomy in a thirteen years period were reviewed, collecting their demographic, ultrasonograpbic and histopathological data. Results: One hundred and twenty three patients were operated. Tbe mean age was 44 +/- 13 years, and 69% were women. The mean size of polyps in ultrasonography was 7.3 +/- 5 mm. Histopathology confirmed the presence of polyps in 79% of patients, with a mean size and number of lesions of 5.1 +/- 3.8 mm and 2.1 +/- 2, respectively. Nine percent of polyps were greater than 10 mm, and single polyps were significantly larger than the multiple ones (p = 0.003). Four cases of adenoma (3.2%) were diagnosed; one of them had in situ carcinoma. All were single and larger than 10 mm. We found a significant correlation between ultrasonograpbic and histopathological polyp size determination (r = 0.47; p = 0.002). Polyp size was also a predictor of the presence of adenoma (p = 0.043; confidence intervals., 1.006-1.424). Conclusions: There is a good correlation between the size of the gallbladder polyp in ultrasonography and the size in the histopathology report. Gallbladder adenoma is uncommon and it correlates with the size of the polyp. In this series, size was the only predictor of the presence of adenoma.
