Finite element modeling for soft tissue surgery based on linear and nonlinear elasticity behavior.

New surgical techniques require fine control from the surgeon's point of view. Until recently, the necessary experience was only obtainable through traditional training protocols (using cadavers, animals, etc.).

[Pregnancy in type 1 diabetes: insulin pump versus intensified conventional therapy].

Objectives: To evaluate and compare the outcome of pregnancies in women with type 1 diabetes treated with continuous subcutaneous insulin pump or multiple insulin injections.

Patients And Methods: Thirty-three patients treated with pump, 23 with multiple injections. Were mainly investigated: glycemic control (HbA1C), fetal outcome (congenital malformations, preterm delivery, perinatal mortality), rates of gestational hypertension and cesarean section.

[Pregnancy and type 2 diabetes: which fetal prognosis?].

Objectives: The rise in the prevalence of type 2 diabetes in women of childbearing age leads to an increasing number of pregnant women with type 2 diabetes. But published data on fetal outcome are scarce.

Patients And Methods: In a prospective study from 1999 to 2002, we assessed fetal outcome (preterm delivery, perinatal mortality, congenital malformations) in 20 pregnancies associated with type 2 diabetes and compared the outcome to 40 pregnancies associated with type 1 diabetes.

[Gynecologic laparoscopy and abdominal scars: what approach for the peritoneal cavity?].

To identify and discuss the advantages of the different methods of entry into the peritoneal cavity during gynecological laparascopy in patients who have previously undergone abdominal surgical procedures. Literature review comparing the strengths of each method of entering the peritoneal cavity during gynecological laparoscopic procedures. Adhesions increase the risks of access into peritoneal cavity during laparoscopy.

Delayed delivery of second twin: a multicentre study of 35 cases.

Objective: The aim of this study was to conduct a statistical analysis to determine the outcome of conservative treatment after delivery of a first fetus in multiple pregnancy and thus define new prognostic factors.

Study Design: Multicentre retrospective study involving 12 centers over a 10-year period.

Results: Twenty-eight twin pregnancies and seven triplet pregnancies which were managed conservatively.

The treatment of severe pulmonary edema induced by beta adrenergic agonist tocolytic therapy with continuous positive airway pressure delivered by face mask.

We report the case of a pregnant patient who developed severe pulmonary edema secondary to beta-adrenergic agonist tocolytic therapy (salbutamol) and was successfully treated with mask-delivered continuous positive airway pressure ventilation.

[Update on maternal-fetal infections by hepatitis C, HIV and cytomegalovirus].

Maternal infections with hepatitis C virus, human cutomegalovirus and HIV and their management problems continue to raise concern in obstetrics. What should we recommend to decrease the incidence of hepatitis C virus congenital infection? We know that congenital human cytomegalovirus infection can lead to major neurological disease with sensorineuronal loss. The current lack of trusted prognostic elements to predict impact on the infected fetus makes any prenatal diagnosis questionable.

[Ovarian mucinous tumor of gastric and intestinal type associated with Peutz-Jeghers syndrome: in situ hybridization study of apomucin gene transcripts].

Occurrence of mucinous tumors is favored by Peutz-Jeghers syndrome (PJS). A case of bilateral ovarian mucinous tumor associated with ovarian mature teratoma occurring in a 22-year-old woman with PJS was reported. Tumor cells included 5 cell types: tall columnar mucinous pale cells with neutral mucins; goblet cells with acidic nonsulfated mucins; non mucinous columnar cells; mucinous cuboidal cells lining small glands; endocrine cells.

Developmental mucin gene expression in the human respiratory tract.

The epithelial surface of the respiratory tract is coated with a protective film of mucus secreted by epithelial goblet and submucosal gland cells. Histology of the airway mucosa and composition of secretions during the second trimester of fetal life are known to differ from the normal adult in that these secretions show similarities with those of hypersecretory disorders. To provide information regarding cell-specific expression of mucin genes and their relation to developmental patterns of epithelial cytodifferentiation, we studied the expression of eight different mucin genes (MUC1-MUC4, MUC5AC, MUC5B, MUC6, MUC7) in human embryonic and fetal respiratory tract using in situ hybridization.

[Ultrasonic diagnosis of placenta percreta. Apropos of a case with hemorrhagic complication].

Placenta percreta is a rare but severe disease, which is more and more frequent. The reported case shows that diagnosis can be made with B mode and color Doppler ultrasonography. Extension of high-vascularized placenta to the myometrium, abnormal placental-subplacental complex and vascular flow through the myometrium were suggestive of the diagnosis.

[Uterine leiomyosarcomas: a surprising pathology. Review of the literature. Six case reports].

Objective: The aim of this study was to determine the clinical features and laboratory tests which define a population with a high risk of leiomyosarcoma.

Method: A retrospective analysis of 660 hysterectomies performed between 1989 and 1994 was conducted. There were 414 cases of leiomyoma and 6 leiomyosarcomas (1.
