Incidental Finding of a Neuroendocrine Tumor Arising from Meckel Diverticulum During Hernia Repair - A Case Report and Literature Review.

Meckel diverticulum is the most common abnormality of the gastrointestinal tract arising from an incomplete obliteration of the vitelline duct during the intrauterine life. Although tumor development in Meckel diverticulum is not a common situation, it can occur due to the persistence of cellular islets with gastric, pancreatic or intestinal origin. The presence of a neuroendocrine tumor arising from Meckel diverticulum is even scarcer.

Atypical Right Hepatectomy for Liver Metastasis from Ovarian Leiomyosarcoma - A Case Report and Literature Review.

Ovarian leiomyosarcomas are extremely rare ovarian malignancies, usually associated with poor prognosis in terms of survival. Most often, ovarian leiomyosarcomas are diagnosed in postmenopausal women at an advanced stage of disease, the main symptoms consisting of abdominal pain. We present the case of a 52-year-old patient who was initially submitted to surgery for a large ruptured ovarian tumor in April 2009; at that time, total hysterectomy with bilateral adnexectomy, omentectomy, pelvic and para-aortic lymph node dissection were performed.

Results of extension of classic indications of vaginal hysterectomy for benign uterine conditions.

Objective: to compare the results of two surgical approaches: one is to apply vaginal hysterectomy (VH) for non-prolapsed uterus respecting classic indications and contraindications and the other is to extend the indications of VH and decrease the contraindications by performing VH for large uterus, in nulliparous and in women with history of C section.

Study Design: 816 women with benign uterine pathology were included in this prospective study. In 465 were applied classic indications of VH and in 351 VH was applied as first choice, trying to overcome classic contraindications of VH.

Reversal of subclinical left ventricular dysfunction by antihypertensive treatment: a prospective trial of nebivolol against metoprolol.

Objectives: To assess the effects of antihypertensive treatment on subclinical left ventricular dysfunction and to compare the effects of nebivolol with metoprolol.

Methods: This is a prospective, randomized, parallel, active-controlled, PROBE design study (ClinicalTrials.org: NCT00942487) in 60 patients (53±9 years, 67% men) with arterial hypertension, left ventricular hypertrophy, normal ejection fraction, and no coronary heart disease, randomized to either a nebivolol-based or a metoprolol-based treatment, who had conventional and tissue Doppler echocardiography, at rest and during dobutamine stress, at baseline and after 6 months.
