In this study, we tested the hypothesis that rectal immunization with a VCG-based chlamydial vaccine would cross-protect mice against heterologous genital Chlamydia trachomatis infection and Chlamydia-induced upper genital tract pathologies in mice. Female mice were immunized with a C. trachomatis serovar D-derived subunit vaccine or control or live serovar D elementary bodies (EBs) and the ant...

BACKGROUND We evaluated whether measuring chlamydia genus- and species-specific immunoglobulin (Ig) G antibodies might improve the predictive value of C. trachomatis antibody testing (CAT) in screening for distal tubal pathology (DTP). METHODS Serum of 313 subfertile women was tested for the presence of species-specific antibodies to C. trachomatis, C. pneumoniae and C. psittaci and genus-spe...

Background: Tubal pregnancy is a common gynecological acute abdomen, and is often treated by laparoscopic salpingotomy. This study aimed to compare two pituitrin injection methods in laparoscopic salpingotomy for tubal pregnancy. Methods: 200 patients with unruptured tubal pregnancy were randomly divided into observation group 1, observation group 2 and control group. Before laparoscopic salpin...

OBJECTIVE To evaluate the effect of male factor infertility on intracytoplasmic sperm injection (ICSI) outcomes compared with a control group presenting isolated tubal factor. METHOD This retrospective study included 743 couples undergoing ICSI as a result of isolated male factor and a control group consisting of 179 couples undergoing ICSI as a result of isolated tubal factor, performed in a...

Tubal sterilization is one of the contraceptive methods whose use has increased the most in Brazil, but a growing number of women have expressed regret after the procedure. A case-control study was conducted at the Centro Integrado de Saúde Amaury de Medeiros (CISAM), Recife, Pernambuco, Brazil, in 1997 to investigate the association between changes in family structure and request for or submit...

BACKGROUND The role of the innate immune system in tubal implantation remains undefined. This study compared expression of two key mediators of innate immunity, secretory leukocyte protease inhibitor (SLPI) and elafin, in the uterine decidua of women with intrauterine and tubal pregnancies. METHODS Uterine decidua was collected from women (18-45 years) undergoing surgical termination of pregn...

Ectopic pregnancy, a worldwide health problem, is potentially life-threatening and occurs in approximately 1.5-2% of all pregnancies in the western world; however, the precise mechanisms underlying the initiation and development of tubal ectopic pregnancy are unknown. Tubal abnormalities and dysfunction, such as altered contractility or abnormal ciliary activity, have been speculated to lead to...

The da Vinci(®) robotic surgical system has been used more often in recent years for tubal anastomosis (TA) and has been reported to have an increased operative time. A one-stitch technique has been used for the reanastomosis step in laparoscopic TA. To date, publications on robotically-assisted TA (RATA) describe an anastomotic step with multiple (usually four) sutures placed. This retrospecti...

The incidence of ectopic pregnancy is approximately 1.3-2% of all pregnancies, and more than 90% of ectopic pregnancies are detected in the ampulla of the fallopian tube. Ectopic pregnancy occurring in tubal stump after tubectomy is extremely rare, and the frequency of tubal stump pregnancy is approximately 0.4% of all pregnancies. We report one of these rare cases of ectopic pregnancy in a 26-...
