A conformação dos ecomuseus: elementos para compreensão e análise
Apresenta uma histĂłria dos ecomuseus enraizado nos movimentos de folclore e etnografia regional, do final do sĂ©culo XIX atĂ© os dias de hoje, examinando o caso francĂŞs. Explora aspectos em geral menos enfatizados neste campo, tal como a natureza e o papel atribuĂdo aos acervos e ao patrimĂ´nio cultural e padrões museográticos
et al - Primo accesso in chirurgia laparoscopica Primo accesso in chirurgia laParoscoPica
The peritoneal access remains the gravest concern for the laparoscopic surgeon and continues to be a leading cause of complication
during laparoscopic surgery. Choosing the best method of peritoneal access depends on the patient’s phenotype
and clinical history. Since no single methods is completely adaptable for all patients, the surgeon must be knowledgeable
about alternative methods and be able to execute them technically. The aim of the manuscript is to provide clinical direction
on laparoscopic entry techniques and technologies and their associated complications. The laparoscopic surgeon
must be mindful that most life-threatening surgical accidents to the bowel as well as to retroperitoneal vessels occur during
insertion of the Veress needle and primary cannula. We analize the different laparoscopic entry techniques and technologies
including the classic pneumoperitoneum (Veress/trocar), the open (Hasson), the direct trocar insertion, the use of
disposable shielded trocars, radially expanding trocars, and visual entry systems.

Umbilical cord segmental hemorrhage and fetal distress
We describe an unexplained case of umbilical cord segmental hemorrhage linked with meconium-stained amniotic fluid. A severely asphyxiated infant was delivered at term by Caesarean section. There were poor prognostic signs on fetal cardiotocography with rupture of membranes with meconium-stained amniotic fluid. The pathophysiologic mechanism in this case is still unknown, even if we argued a possible role of the umbilical cord shortness
Ultrasound detection of the "sliding viscera" sign promotes safer laparoscopy.
To estimate the feasibility of preoperative ultrasound evaluation of the umbilical region in patients undergoing laparoscopy with a previous history of abdominal surgery.Prospective study (Canadian Task Force Classification II-1).Department of Obstetrics and Gynecology Fatebenefratelli Isola Tiberina Hospital.Twenty-five women with a previous history of open abdominal surgery (group A) and a group of 22 women with no previous history of surgery (group B) underwent dynamic ultrasound evaluation of the umbilical field.Ultrasound Slide-By test.Patients were asked to take a deep inspiratory breath, which accentuated respiratory excursion. The movement of the intraabdominal contents in a vertical fashion in relation to the abdominal wall, referred to as the "viscera slide," between the bowel and peritoneum was evaluated. Abdominal wall tissue thickness, Uracus to peritoneum thickness (UTP, mm) were also evaluated. Non parametric Mann-Whitney testing was used. No major demographic differences between the 2 study groups was noted. The abdominal wall tissue thickness was not significantly different between the 2 groups. The UTP was shorter in A group than in B group (1.5 +/- 0.3 mm vs 3.5 +/- 0.9 mm, p = .002). Absence of the "sliding viscera" sign was observed in 16 patients in group A and in 1 patient in group B. Patients with an absence of the sliding viscera sign were found to have subumbilical fibrous adhesions during laparoscopy.Evaluation of trocar insertion sites may be difficult and remains a challenge for peritoneal endosurgical access. We have shown that absence of the "sliding viscera" sign is more likely to be linked to subumbilical adhesions and represents a quick method for preoperative assessment. The UTP may also be a useful measurement, which requires further validation

Ultrasound-determined fetal subcutaneous tissue thickness for a birthweight prediction model
The aim of this study was to explore a birthweight prediction model using ultrasound determined tissue thickness (SCTT) parameters
