What kind of surgery for cervical carcinoma?

The incidence and mortality of cervical cancer have changed over the past 50 years in developed countries, but this kind of tumor still remains a significant clinical problem because it is the second most common cause of morbidity and mortality from cancer among women. After histological confirmation of invasive cervical cancer, the extent of disease was determined using clinical criteria to assign a stage. This assessment is important because, while for the other gynecologic cancers clinical information obtained by surgery and histopathological examination is implemented and concurs to define the staging of the disease, the cervical cancer tumor stage is given after the primary diagnosis. In this review we discuss how the surgical approach to cervical cancer has been evolved, in order to modulate the radicality of the intervention itself and thus to preserve the pelvic innervation. This step has been achieved by deepening knowledge of functional pelvic anatomy and modulating the radicality of hysterectomy according to well defined surgical landmarks.

Mayer-Rokitansky-Küster-Hauser syndrome presenting as vaginal atresia: report of two cases.

Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome) is characterized by Müllerian duct structures agenesis: the vagina atresia is the commonest variant. There can be some anomalies associated, such as renal, skeletal, spine malformations and others. Patients with MRKH can show different presentation from newborn period to adolescence. We report our experience in treatment of the vaginal atresia presenting in two young girls as a sign of MRKH syndrome.

Gestosis and fetal rejection: immunopathogenetic role of HLA-DR.

In this study we faced the problem of etiopathogenesis of EPH Gestosis, focusing our attention on the role of immunitary aspects in determining its onset. We typed HLA-DR in 20 couples with gestosic patient and in 20 control couples. Blood samples were taken into heparin-treated test tubes, from all the couples and HLA typed through standard lymphotoxicity technique in accordance with Terasaky (1). Our results in couples with a gestosic patient, showed homozygosis in 65% of patients and in 70% of partners; in 35% of cases homozygosis was present in both partners, and these were the most severe cases. It is also worth mentioning that in all the couples with gestosic patient, at least one of the partners resulted homozygotic. Homozygosis would therefore represent a predisposing factor in the etiopathogenesis of gestosis, and pre-conception HLA-DR typing of the couple could prove to be a valid alarm signal for gestosis risk.

Immunohistochemical study of placental endothelium in physiologic and gestosis-complicated pregnancies.

In this study we examined the placentae of gestosic patients and controls, with immunoistochemical method and HLA-DR monoclonal antibody, in order to show the role of placental endothelium in gestosic pathology onset. Our results show a marked expression of class II histocompatibility antigens in gestosic placentae with respect to controls. We suppose, in gestosic patients, a role for a particular, genetically determined HLA haplotype which increases disease receptivity.

Cell-mediated immunity in the course of cervical ectropion.

In the present study we evaluated cellular immunitary response in course of asymptomatic ectropion. Biopsies of the injured and healthy zones of the exocervix were carried out. All biopsies were examined by an immuno-histo-chemical method (Avidin-Biotin Complex, ABC) with monoclonal antibodies, in order to phenotype T lymphocytic subpopulations, in particular T helper lymphocytes (CD4), T suppressor lymphocytes (CD8) and Langerhans cells (CD1), which are basic elements of the monocytic-macrophagic series. Our preliminary findings showed a reduction of CD4, CD8 and CD1 lymphocytic subpopulations in ectropion zones, while these subpopulations are normally present in healthy zones of the exocervix. These findings support the hypothesis that, in ectropion, as in HPV infections and in CIN, a localized immuno-deficiency may appear and depress immuno-surveillance and cell-mediated response. In conclusion, it may be supposed that ectropion represents a non-stable lesion, which therefore needs suitable therapeutic intervention.

[Topical therapy with placental polydeoxyribonucleotide in cervical ectopy and ectropion]. / Terapia topica con polidesossiribonucleotide placentare nella ectopia e nell'ectropion cervicali.

Twenty outpatients, aged 18-45 yrs, with cervical ectropion have been treated with vaginal suppositories of PDRN (a placental derivate). The drug has been given randomly in two preparations of 5 g and 10 g, however both containing the same amount of the active component (5 mg). The results show the effectiveness of the eutrophic and antiphlogistic action of both preparations, with a remarkable reduction of the leukorrhea. The patients preferred the vaginal suppositories of 5g both for the greater maniability and for the smaller vaginal discharge after the administration. The reduction of the excipients in the new vaginal tablets, besides improving the compliance of patients, brings about a longer contact of the drug with the vaginal walls, hence a better bioavailability of the active principle.
