Combined Systemic and Hysteroscopic Intra-Amniotic Injection of Methotrexate Associated with Hysteroscopic Resection for Cervical Pregnancy: A Cutting-Edge Approach for an Uncommon Condition.

This case report of a 36-year-old woman with a diagnosis of cervical pregnancy describes a novel approach to this rare form of ectopic pregnancy, which was successfully treated with systemic and local methotrexate (MTX) therapy combined with hysteroscopic resection. After local and systemic administration of MTX, the patient underwent hysteroscopic resection of the cervical pregnancy using a 27 bipolar resectoscope with a 4-mm loop. The cervical pregnancy was completely treated, and satisfactory hemostasis was achieved with electrocoagulation.

Uterine Wound Healing: A Complex Process Mediated by Proteins and Peptides.

Wound healing is the process by which a complex cascade of biochemical events is responsible of the repair the damage. In vivo, studies in humans and mice suggest that healing and post-healing heterogeneous behavior of the surgically wounded myometrium is both phenotype and genotype dependent. Uterine wound healing process involves many cells: endothelial cells, neutrophils, monocytes/macrophages, lymphocytes, fibroblasts, myometrial cells as well a stem cell population found in the myometrium, myoSP (side population of myometrial cells).

Pelvic adhesion and gonadotropin-releasing hormone analogue: effects of triptorelin acetate depot on coagulation and fibrinolytic activities.

The study investigated the impact of gonadotropin-releasing hormone analogue (GnRH-a) on coagulation and fibrinolytic activities and its effectiveness in the prevention of pelvic adhesion after myomectomy. Thirty-two infertile women underwent myomectomy followed by adhesion evaluation surgery with a second-look laparoscopy. Before myomectomy, 15 women were treated with triptorelin acetate for 3 months and 17 received no treatment.

Objective: To evaluate if pre-operative GnRH-a modify uterine leiomyoma pseudocapsule and the possible clinical effects of these changes.

Study Design: The study was performed at the University Federico II of Naples on 33 premenopausal patients submitted to laparotomic myomectomy after treatment with triptorelin depot. 29 untreated patients formed the control group.

Regional and international prenatal telemedicine network for computerized antepartum cardiotocography.

The objective of this work was to review the activity of TOCOMAT, a system for antepartum cardiotocographic telemonitoring. Nine peripheral units recorded the traces, transmitted them via modem to the University operation center, where the computerized analysis was performed, and received the medical report within a few minutes, via fax or e-mail. Traces were classified as reassuring, nonreassuring, or pathological.

Severe secondary postpartum hemorrhage 3 weeks after cesarean section: alternative etiologies of uterine scar non-union.

A case of secondary postpartum hemorrhage that occurred 3 weeks after cesarean section requiring total abdominal hysterectomy is reported. The patient's history and pathologic features of the removed uterus did not allow the authors to clearly recognize a previous reported cause of this potentially life-threatening complication. Alternative causes of the non-union of the uterine incision are suggested.

Four years' experience with antepartum cardiotocography using telemedicine.

We reviewed the first four years of experience with telemonitoring of patients with high-risk pregnancies. Nine peripheral units (eight in Campania, a region of south Italy, and one in Hungary) recorded cardiotocographic traces and transmitted them via modem to an operations centre at the University 'Federico II' in Naples, where the computerized analysis was performed. The medical report was returned to the peripheral unit via fax or email.

Objective: To evaluate the clinical features and the expression of transforming growth factor-beta3 (TGF-beta3) and connective tissue growth factor (CTGF) in myometrium and uterine leiomyomas after preoperative treatment with gonadotropin-releasing hormone-analogs (GnRH-a) and tibolone.

Methods: Twenty-three patients received 3.75 mg leuprolide acetate depot for 4 months.

Uterine dehiscence in term pregnant patients with one previous cesarean delivery: growth factor immunoexpression and collagen content in the scarred lower uterine segment.

Objective: This study aimed at investigating the relationship between the occurrence of uterine dehiscence in term pregnant scarred uteri and the presence of altered biochemical behavior of the scarring process.

Study Design: Collagen content and the expression of transforming growth factor-beta and its isoforms transforming growth factor-beta1 and transforming growth factor-beta3, connective tissue growth factor, basic fibroblast growth factor, vascular endothelial growth factor, platelet-derived growth factor, and tumor necrosis factor-alpha in myometrium of lower uterine segment were assessed in 19 otherwise healthy term patients with one previous cesarean delivery who were not in labor. We were searching for differences between patients who showed uterine dehiscence (9 cases) and patients who showed a normal-appearing scarred lower uterine segment (10 cases).

Antepartum cardiotocography: a study of fetal reactivity in frequency domain.

Cardiotocography (CTG) is the most widely used diagnostic technique in clinical practice to monitor fetal health. Cardiotocographic recording also permits to assess maturation of the fetal autonomous nervous system (ANS): fetal heart rate (FHR) modifications may reveal ANS' reactions to stimuli. To assess fetal reactivity, physicians evaluate specific clinical CTG parameters, generally, by means of visual inspection, thus depending on observer's expertise, with lack of reproducibility.

Erythropoietin and erythropoietin receptor system in a large uterine myoma of a patient with myomatous erythrocytosis syndrome: possible relationship with the pathogenesis of unusual tumor size.

The rare condition of women with erythrocytosis and a concurrent myomatous uterus has been classified as "myomatous erythrocytosis syndrome". Substantial myoma size has been noted as a common denominator in this condition in which recent evidence have confirmed erythropoietin (Epo) production by myoma tissues themselves. Apart from its primary endocrine role in controlling erythropoiesis, Epo has been demonstrated to mediate several cellular processes such as angiogenesis, mitogenesis, and inhibition of apoptosis by autocrine and paracrine mechanisms.

Clinical response, vascular change, and angiogenesis in gonadotropin-releasing hormone analogue-treated women with uterine myomas.

Objective: Basic fibroblast growth factor (bFGF), vascular endothelial growth factor (VEGF), and platelet-derived growth factor (PDGF) are involved in the pathogenesis of leiomyomas and influence angiogenesis, which is necessary for growth of leiomyomas. Gonadotropin-releasing hormone analogue (GnRH-a) treatment might modify the growth factor expression and the blood supply in myomas. We investigated the effects of GnRH-a treatment on some clinical parameters, on the immunohistochemical expression of bFGF, VEGF, and PDGF, and on the vasculature of leiomyomas.

Preoperative administration of GnRH-a plus tibolone to premenopausal women with uterine fibroids: evaluation of the clinical response, the immunohistochemical expression of PDGF, bFGF and VEGF and the vascular pattern.

Aim of the study is to compare the effects of preoperative therapy with tibolone plus gonadotropin-releasing hormone analogue (GnRH-a) in premenopausal women with those of GnRH-a alone on clinical response, uterine volume, immunohistochemical expression of platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) and vascular features of myomas. Seventy women with symptomatic uterine fibromatosis were treated for four months with leuprorelin acetate alone or plus tibolone. Untreated patients were submitted to uterine surgery directly.

A cost study of prenatal telemedicine.

We calculated the cost of using a telemedicine system for the cardiotocographic (CTG) recording of fetal heart rate. In a one-year study in the Campania region of Italy, 162 patients were monitored. The total cost of the telemedicine system was euro;344796.

Collagen content and growth factor immunoexpression in uterine lower segment of type IA osteogenesis imperfecta: Relationship with recurrent uterine rupture in pregnancy.

Objective: The purpose of this study was to evaluate collagen content and platelet-derived growth factor, vascular endothelial growth factor, and connective tissue growth factor expression in the myometrium of the uterine lower segment from a patient with type IA osteogenesis imperfecta with recurrent uterine rupture and to evaluate the existence of a relationship between the rare recurrent uterine rupture and the tissue disorders of type IA osteogenesis imperfecta.

Study Design: Collagen content and platelet-derived growth factor, vascular endothelial growth factor, and connective tissue growth factor expression in the uterine lower segment were assessed in the patient with type IA osteogenesis imperfecta and in eight otherwise healthy ("control") patients.

Results: Type IA osteogenesis imperfecta contained less total collagen amount, with no difference in type III collagen expression and showed increased levels of platelet-derived growth factor and vascular endothelial growth factor in myometrial smooth muscle cells.

Objective: To describe the clinical results of the first working year of a telemedicine project based on computerised telecardiotocography.

Study Design: The project is based on the "TOCOMAT" system, which remotely recorded and processed cardiotocograms performed at five peripheral units from high and low risk patients, then transferred them to a University Operative Centre, where they were displayed, stored and analysed by the 2CTG system and by two expert observers.

Results: 457 traces were analysed.

Relationship between platelet-derived growth factor expression in leiomyomas and uterine volume changes after gonadotropin-releasing hormone agonist treatment.

The unopposed estrogen effect is the main cause of leiomyoma growth and is at the basis of the clinical use of gonadotropin-releasing hormone (GnRH) agonists. Platelet-derived growth factor (PDGF) has been indicated as the main growth factor involved, in vitro in the proliferation response of leiomyoma smooth muscle cells to estrogen stimulation. The aim of this article is to evaluate the mitogenic action of PDGF in vivo by studying the relationship between PDGF expression in leiomyomas and post-GnRH analogue treatment changes in uterine volume.
