RESUMEN

The incidence of young women diagnosed with cancer has been globally increasing. In many cases the surgical approach followed by chemotherapy, radiotherapy or hormonal therapy could lead to infertility or premature ovarian failure. Several options are available in order to preserve fertility and increase the future gestation rate. Among embryo cryopreservation and oocyte cryopreservation, ovarian tissue cryopreservation represents an ideal option, especially for premenopausal women and for those who cannot delay the start of chemotherapy. The purpose of this study was to examine the follicle viability using fluorescence microscope before and after ovarian thawing.

RESUMEN

AIM: Primary ovarian non-Hodgkin's lymphoma is a very rare disease. Median age at diagnosis is estimated at 42 years, something that leads to fertility preservation issues in many cases. This was a case report study, presenting a rare case of bilateral primary ovarian non-Hodgkin's lymphoma. CASE REPORT: A 38-year old nulliparous woman, underwent exploratory laparotomy because of bilateral ovarian masses. Left salpingooophorectomy, partial omentectomy and excision of an ovarian mass of the right ovary was performed. Great effort in order to preserve healthy ovarian tissue of the right ovary as well as the right fallopian tube was given, due to fertility reasons. Final histology showed bilateral diffuse large B-cell primary ovarian non-Hodgkin's lymphoma. Postoperatively, the patient underwent chemotherapy with the CHOP regimen in combination with rituximab. Five years after initial diagnosis, the patient remains well with normal menstrual cycle, without evidence of recurrence. DISCUSSION: Fertility preservation issues in some cases of rare gynecological malignancies could be managed via minimally invasive oncological approach.

RESUMEN

PURPOSE: The objective of this study was to evaluate the effect oftamoxifen on the endometrium of45 postmenopausal women with breast cancer, as evidenced by hysteroscopic, ultrasound, histological methods, and by immunohistochemical investigation of the expression of Bcl-2 and Ki67. MATERIALS AND METHODS: Forty-five postmenopausal women with breast cancer (ER and/or PgR positive) undergoing tamoxifen therapy for six to 48 months, were selected from the files of the 2nd Department of Obstetrics and Gynecology, University of Athens Aretaieion Hospital, among a total of 120 patients treated from 2004-2009. RESULTS: The ultrasound findings during the follow-up period revealed 18 cases of thickened endometrium, 14 cases of suspected polyps, one case with accumulation of endometrial fluid, and 12 cases of heterogeneous endometrial echo texture. The patients had undergone hysteroscopy because of thickened endometrium (18/45 patients), postmenopausal bleeding (14/45 patients), and polyps (13/45 patients). The endometrial tissue samples were examined in the Pathology Department of Aretaieion Hospital and showed in 23 cases with adenomatous endometrial polyps, 15 cases with endometrial cystic atrophy, two cases with adenomatous hyperplasia, and five cases with mucosal endometrial adhesions. Immunohistochemical investigation of Bcl-2 and KJ67 expression was undertaken on paraffin blocks and showed elevated expression in the cases with endometrial polyps and hyperplasia, in contrast to atrophic endometria. CONCLUSION: Long-term tamoxifen therapy of postmenopausal women with breast cancer is associated with uterine pathology. Ultrasonography alone is useful in asymptomatic patients selecting cases with increased endometrial thickness for further investigation. Hysteroscopy is an accurate method for diagnosing endometrial disease because it provides a direct view of the uterine cavity, reveals focal lesions, and enables targeted biopsies to be performed at the same time. Pathological findings show elevated expression of Ki67 and Bcl-2 in hyperplastic endometria and adenomatous polyps, consistent with an elevated glandular cell proliferation due to tamoxifen effect.

RESUMEN

We present three consecutive cases of skeletal dysplasias of a non-consanguineous couple with five pregnancies. The diagnosis of short-rib polydactyly syndrome (SRPS) was feasible by ultrasound during the 1st trimester of pregnancy. SRPS represents a heterogeneous group of lethal skeletal dysplasias. It is characterised by short limb dwarfism complicated by thoracic hypoplasia, polydactyly and different anomalies of major organs such as congenital heart defects and renal dysplasia. Four major types of the SRPS have been described: type I (Saldino-Noonan); type II (Majewski); type III (Verma-Naumoff) and type IV (Beemar-Langer). However, there is phenotypic overlapping between four types and with those of non-lethal skeletal dysplasias (i.e. Ellis-van Creveld syndrome and Jeune syndrome). Our cases show the importance of the nuchal translucency (NT) scan that offers the opportunity to examine fetal anatomy in the 1st trimester and diagnose rare skeletal abnormalities early in pregnancy.

RESUMEN

OBJECTIVE: We investigated whether the concentration of the glycoprotein fetuin A is altered in the second trimester amniotic fluid of trisomy 21 pregnancies compared with euploid pregnancies. METHODS: 25 pregnancies with an extra chromosome 21 were matched for maternal and gestational age with 25 pregnancies with normal karyotype. Levels of fetuin A in amniotic fluid were measured by a commercially available enzyme-linked immunosorbent assay (ELISA) kit. RESULTS: The median concentration of fetuin A in amniotic fluid of trisomy 21 pregnancies (5.3 ng/ml) was statistically significantly lower (P value = 0.008) compared with that in euploid pregnancies (6.8 ng/mL). CONCLUSION: Lower levels of fetuin A in trisomy 21 may indicate an association with altered metabolic pathways in this early stage that could potentially be associated with features of the syndrome, such as growth restriction or impaired osteogenesis.

RESUMEN

PURPOSE: To assess the diagnostic value of transvaginal sonography (TVS) measurement of the endometrium compared to hysteroscopic findings and histopathologic reports in order to facilitate clinical management in asymptomatic postmenopausal women with thickened endometrium. METHODS: During the period between January 2000 and December 2008, a retrospective analysis was performed including cases of women who were preoperatively diagnosed with a sonographically thickened endometrium, while asymptomatic, and therefore underwent hysteroscopic and fractionated dilatation and curettage (D & C) under general anesthesia at the Second Department of Obstetrics and Gynecology at Aretaieion Hospital in Athens, Greece. In the present study we compare US, hysteroscopic and pathologic findings. RESULTS: The mean age of the patients ranged between 54-74 years (mean age 65.2 +/- 6.8 years). In 108 cases, sonographically measured endometrial thickness ranged between 5 and 10 mm. In 59 cases, endometrial thickness ranged between 11 and 15 mm, whereas in 22 cases, between 16 and 20 mm and finally, in 13 cases endometrial thickness was more than 20 mm. Hysteroscopic examination revealed endometrial polyps in 161 cases, focal hyperplastic lesions in 28 cases, complete hyperplastic lesions in five cases while atrophy was found in five and cancer in three cases, respectively. Pathological results of the samples taken after hysteroscopy are as follows: in 169 cases (83.67%) in women with asymptomatic abnormal endometrial thickness, an endometrial polyp was present. Endometrial thickness in these cases patients was 10.9 +/- 7.5 mm. In patients with focal hyperplasia (22 cases), endometrial thickness was 7.2 +/- 0.5 mm but in patients with complete hyperplasia (5 cases) endometrial thickness was higher (12.3 +/- 5.1 mm). Finally, in three cases with endometrial carcinoma endometrial thickness was 15.5 +/- 7.8 mm. Six cases out of 28 described in our study were diagnosed as focal hyperplasia and two out of five cases as complete hyperplasia, whereas histological reports classified these cases as endometrial polyps. The other histological diagnoses confirmed hysteroscopic findings and thus provided the same results. CONCLUSIONS: We recommend hysteroscopy to follow gynecological TVS when a thickened endometrium is found in asyptomatic postmenopausal women for better diagnostic and, in a later stage, therapeutic efficacy.

RESUMEN

The aim of this study was to describe a new technique for laparoscopic removal of large ovarian cystic masses. The authors performed a retrospective study during the period January 2008 to December 2009 in the Second Department of Obstetrics and Gynecology of Aretaieion University Hospital; 19 women with large ovarian cysts were included in the study. During the study period, 53 women underwent laparoscopic excision of ovarian cysts. Among them, 19 had very large complex ovarian cysts with a mean diameter of 8.4 cm. The mean age of the patients was 32.1 years. Ultrasound examination revealed findings suggestive of benign disease in all patients. In 8 out of 19 patients CA-125 levels were elevated, ranging from 40.5 to 194.7 IU/mL. A 5-mm suprapubic trocar was directly inserted into the cyst and fluid contents aspirated, so the decompressed cyst could fit in a 5-cm laparoscopic bag. The cyst wall was carefully detached from the healthy ovarian tissue and placed in the bag without any spillage. The remaining cyst wall was removed from the peritoneal cavity with the laparoscopic bag. The mean operative time was 45 minutes. No operative or postoperative complications were noted. There was no conversion to laparotomy. Mean hospital stay was 1 day. Pathology revealed 7 endometriomas, 3 mucinous cystadenomas, 3 serous cystadenomas, 3 serous cysts, and 3 teratomas. Direct trocar insertion within the ovarian cyst followed by aspiration of the fluid contents is a safe and feasible method for the laparoscopic management of large ovarian cysts.

RESUMEN

PURPOSE OF INVESTIGATION: To evaluate the diagnostic accuracy of three-dimensional ultrasound (3D-US) and three-dimensional power-Doppler (3DPD-US) as adjuncts to conventional B-mode-US in evaluation of complex benign ovarian lesions. METHODS: Transvaginal B-mode-US, 3D-US and 3DPD-US were performed in 29 patients with unilateral ovarian lesion. Patients were classified as low or high risk for malignancy according to a standardized scoring system composed of ten morphological and vascular parameters. Preoperative scores were matched to the histological results and the diagnostic performance of the scoring system was calculated. RESULTS: Seven out of the 16 cases of endometriomas (44%) were graded as low risk masses according to B-mode-US, while the addition of 3D-US and 3DPD-US increased the accuracy to 56% and 94%, respectively. All dermoid cysts were classified as high risk cases by B-mode-US, but 3D-US and 3DPD-US correctly classified 14% and 57% of cases, respectively. The use of B-mode-US, 3D-US and 3DPD-US correctly classified all four cystadenomas. Only the use of 3DPD-US correctly classified one out of two hemorrhagic corpus luteum cases, whereas the other imaging modalities characterized these lesions as high risk. The overall diagnostic accuracy increased from 38%, 48%, ana 83% with the application of B-mode-US alone, or combined with 3D-US and 3DPD-US, respectively. CONCLUSION: Conventional ultrasound supplemented with 3D-US and 3DPD-US and the evaluation of findings according to a specific scoring system can facilitate the preoperative classification of complex benign ovarian lesions.

RESUMEN

AIM: Human beta defensins 2 (HBD2) and 3 (HBD3) are peptides expressed in the amnion and chorion. This is a matched case control study conducted in our Department to determine whether second trimester amniotic fluid HBD2 and HBD3 concentrations measured at the time of genetic amniocentesis could be potential markers of preterm labor prediction. METHODS: Amniotic fluid HBD2 and HBD3 were determined by an enzyme-linked immunosorbent assay (ELISA) Women with preterm labor were defined as cases (N=41) while for each case a woman matched for age delivering at term served as control (N=41). Subgroup analysis was conducted to examine possible associations of HBD2 and HBD3 in cases of premature rupture of membranes. Nineteen women with preterm labor and premature rupture of membranes were defined as cases while for every case a woman matched for maternal age delivering at term served as control (N1=19). Results were presented as odds ratios (OR) and 95% confidence intervals. Statistical analysis used STATA 8.2 and SPSS 11.5 edition. A P-value of <0.05 was considered statistically significant. RESULTS: Amniotic fluid concentrations of HBD2 at the time of genetic amniocentesis were positively associated with preterm premature rupture of membranes (P=0.028), but not with preterm labour. No association of HBD3 and preterm birth was documented. CONCLUSION: Second trimester amniotic fluid HBD2 might be a predictor of premature rupture of membranes.

RESUMEN

PURPOSE: Fibronectin (FBN) is involved in the motility and migration of malignant cells. The purpose of this study was to investigate FBN plasma levels in gynecological cancers patients and in healthy women. METHODS: The study took place between 1998 and 2003. One hundred women with histologically diagnosed cancer of gynecological organs (cervix, ovary, endometrium, breast) formed the study group (group A), whereas the control group (group B) consisted of 100 healthy women. FBN plasma levels were measured with the radial immunodiffusion method. RESULTS: The average age of group A patients was 42.08 years (range 33-77), and of group B it was 41.1 years (range 32-65). Both groups were compared with the Student's-t test. The median plasma value of FBN in all gynecological malignancies was 258.4 mg/l (standard deviation/SD 163.9, p=0.0066, t-statistics: 2.768, (t95): 1.984, 95% CI: 225.4-290.9). The plasma levels were significantly elevated when compared to the control group (median=213 mg/l). The distribution of values showed a statistically important "tail" in high plasma levels (FBN >400 mg/l). Plasma levels of FBN were more increased in breast and cervical malignancies when compared to ovarian and endometrial cancers. CONCLUSION: FBN plasma levels were significantly increased in the total of group A patients, but not significantly increased in the endometrial and ovarian subgroup. Whether or not FBN could reliably be a marker for gynecological cancers should be confirmed in studies with larger number of patients.

RESUMEN

OBJECTIVE: Autoimmune thyroiditis and overt or subclinical hypothyroidism have been associated with increased prevalence of cardiovascular disease (CVD). DESIGN: Cross-sectional investigation of the association between gene polymorphisms related to CVD with thyroid function and autoimmunity. PATIENTS: In total 84 healthy postmenopausal women aged 49-69 years. MEASUREMENTS: FT3, FT4, anti-TPO and anti-TG were assessed in the sera of participants. The following polymorphisms were assessed from peripheral lymphocyte DNA: Apolipoprotein E E2/E3/E4, paraoxonase 1 A/B, Glycoprotein IIIa leu33pro, MTHFR ala222val, ApoBarg3500gln, plasminogen activator inhibitor 1 4G/5G, cholesterol 7-alpha hydroxylase A204C and cholesterol ester transfer protein B1/B2. RESULTS: A statistically significant correlation was found between Apolipoprotein E and paraoxonase 1 polymorphisms and serum thyroid hormones: carriers of the E2 or E4 allele of the ApoE gene had lower levels of FT4 (P = 0.0005) than women with the E3/E3 genotype. Carriers of the B allele of paraoxonase 1 gene had lower levels of FT3 compared to women with the wild-type genotype (P = 0.047). A statistically significant positive association (P = 0.049) was also observed between anti-TG antibodies and the presence of the E2 allele of the Apolipoprotein E gene. CONCLUSIONS: Polymorphisms of apolipoprotein E and paraoxonase 1 are associated with different levels of thyroid hormone and anti-Tg antibody levels in the study population in this pilot study. The mechanism underlying this association remains to be elucidated.

RESUMEN

Congenital cystic adenomatoid malformations of the fetal lung (CCAM) are rare embryonic developmental abnormalities. They are considered as benign hamartomatous or dysplastic lung tumors characterized by overgrowth of the terminal respiratory bronchioles at the expense of the saccular spaces. A minority of cases may not be identified by prenatal imaging techniques and the pulmonary lesions are recognized postnatally. Two cases of congenital cystic adenomatoid malformation of the fetal lung diagnosed in our institution during the last four years are reported. The ultrasonographic and pathologic findings of these cases are discussed.

RESUMEN

AIM: The aim of our study was to verify with the use of ultrasound (US) scanning the effectiveness of misoprostol in medical abortion. MATERIALS AND METHODS: The study population included women with a medical miscarriage attending the 2nd Department of Obstetrics and Gynecology, University of Athens in Aretaieion Hospital, Athens, Greece. All women < 49 days since their last menstruation received 800 microg vaginal misoprostol. The diagnosis of complete abortion was possible by the US measurements as endometrial thickness of 15 mm by transvaginal US was used as a cutoff level for successful abortion. RESULTS: The mean age of the study population was 27 years (ranging from 19 up to 37 years). Complete evacuation with misoprostol was performed in 149 women. The success rate was 85.2% (127/149). Twenty-two women experienced intrauterine echogenic structures with a diameter > 15 mm and all of them underwent surgical evacuation (14.8%). Vaginal bleeding was present in 17 patients after the procedure (11.4%). Less usual reported side-effects included nausea, vomiting, pain, or diarrhea. CONCLUSION: Misoprostol use is an effective, safe and acceptable method of medical abortion for women.

RESUMEN

The evaluation of fetal well-being by Doppler velocimetry in cases of intrauterine growth restriction (IUGR) is of great importance as it is very useful in detecting those IUGR fetuses that are at high risk because of hypoxemia. Several Doppler studies initially on fetal arteries and recently on the fetal venous system provide valuable information for the clinicians concerning the optimal time to deliver. Doppler sonography in combination with the other biophysical methods such as cardiotocogram and biophysical profile score should be used in everyday practice for the monitoring and appropriate management of the growth-restricted fetuses. The purpose of this review is to describe the current approaches in Doppler assessment of IUGR fetal circulation.

RESUMEN

Coronary artery disease (CAD) is the main contributor of mortality among postmenopausal women. Menopause-associated estrogen deficiency has both metabolic and vascular consequences that increase the risk for CAD. Hormone therapy (HT) has been reported to have a beneficial effect on metabolic and vascular factors influencing the incidence of CAD. Although observational studies have reported that HT reduces significantly the risk for CAD, randomized clinical trials (WHI, HERS, ERA) have questioned the efficacy of HT in primary and secondary CAD prevention despite confirming the lipid-lowering effect of HT. In the aftermath of the WHI, increased interest has been given to the action of selective estrogen receptor modulators (SERMs) and their effect on the cardiovascular system. The chemical structure of SERMs, either triphenylethilyn (tamoxifen) or benzothiophene (raloxifene) derivatives, differs from that of estrogens. SERMs are nonsteroidal molecules that bind, with high affinity, to the ER. SERMs induce conformational changes to the ligand-binding domain of the ER that modulate the ability of the ER to interact with coregulator proteins. The relative balance of coregulators within a cell determines the transcriptional activity of the receptor-ligand complex. SERMs therefore may express an estrogen-agonist or estrogen-antagonist effect depending on the tissue targeted. SERMs express variable effects on the metabolic and vascular factors influencing the incidence of CAD. SERMs have been reported to modulate favorably the lipid-lipoprotein profile. Toremifene expresses the most beneficial effect followed by tamoxifene and raloxifene, while ospexifene and HMR-3339 have the least effect and may even increase triglycerides. Raloxifene and tamoxifene decrease serum homocysteine levels and C-reactive proteins (CRP), which are both markers of CAD risk. Raloxifene has been reported to increase the nitric oxide (NO)-endothelin (ET)-1 ratio and, thus, contribute to proper endothelial function and vasodilation. Toremifene has no effect on the NO-ET-1 ratio. Finally, raloxifene decreases the vascular cell adhesion molecules and the inflammatory cytokines TNF-alpha and IL-6. Of the SERMs, raloxifene has had the most extensive evaluation regarding the effect on the vascular wall of endothelium. Although not confirmed by large clinical trials, raloxifene has been reported to have an effect on the cohesion of the intercellular junction (VE-cadherin) and the synthesis-degradation of extracellular matrix (MMP-2). The Multiple Outcomes Raloxifene Evaluation (MORE) study has reported that raloxifene may have a cardioprotective effect when administered to postmenopausal women at high risk for CAD disease.

RESUMEN

BACKGROUND: Intrauterine fetal development is characterized by increased rates of proliferation and apoptosis, while both these processes may be attenuated post-natally. AIM: Tissue polypeptide specific antigen and sFas serum concentrations were determined during pregnancy and post-natally, in order to evaluate their alterations during these crucial periods. MATERIALS AND METHODS: Forty-seven healthy pregnant women, their full-term newborns and 35 healthy adults (controls) were included in the study. Markers were measured: (a) in maternal serum (MS), during the 1st, 2nd, 3rd trimester and at the 1st stage of labor; (b) in the umbilical cord (UC), during the 2nd stage of labor; (c) in neonatal serum in the 1st (IN) and 5th (5N) day after birth; and (d) in controls. RESULTS: The serum TPS concentrations in MS increased significantly with gestational age, being higher in the 3rd trimester and labor, than those in controls (p < 0.001). TPS values were significantly lower in the UC, compared to those in MS (p < 0.001), while they were markedly elevated in IN, compared to MS and UC (p < 0.001), and subsequently decreased in 5N (p < 0.001), remaining higher, than those in the controls (p < 0.001). Serum sFas concentrations in the MS depended significantly on gestational age (p < 0.001), being significantly lower in the first trimester, than those in the second (p < 0.003), the third (p < 0.03), in labor and controls (p < 0.005). sFas concentrations in the UC were significantly lower than in MS and controls (p < 0.001), while they increased significantly in 5N samples (p < 0.01). CONCLUSION: Our results demonstrate: (a) a higher apoptosis rate in the first trimester of pregnancy, possibly affecting maternal immuno-tolerance, followed by a down-regulation during the post-natal period; (b) a progressively increased proliferation from the first trimester to parturition, reflecting the fetal and placental growth and development, that seems to be thereafter moderated.

RESUMEN

OBJECTIVE: To study the histopathological features of mesenchymal tumors of the uterine corpus with heterologous and hematopoietic components, and review their histogenesis and differential diagnosis from other neoplastic and non-neoplastic lesions. METHODS: Ten cases of mesenchymal tumors of the uterine corpus, massively infiltrated by hematopoioetic cells, or composed of other benign heterologous elements (adipose tissue in the present cases) were retrieved from the archival files of our laboratory and studied histopathologically. Immunohistochemistry was applied in selected cases. RESULTS: Six of our studied cases were diagnosed as leiomyomas, two as lipoleiomyomas, one as a symplastic lipoleiomyoma, and one as an endometrial stromal tumor. The leiomyomas were massively infiltrated by lymphocytes (5 cases) or eosinophils (one case). Immunohistochemical study of the leiomyomas with massive lymphocytic infiltration revealed the presence of a predominantly B-cell population within the infiltrate, which was polyclonal in nature. The endometrial stromal tumor was severely infiltrated by histiocytes, and was positive for vimentin, CD10, PgR and negative for actin, desmin, ER and caldesmon. CONCLUSION: The presence of hematopoietic or heterologous elements within an otherwise bland uterine leiomyoma or endometrial stromal tumor may give rise to diagnostic difficulties. Regularity of the tumor margins, low mitotic activity and absence of nuclear atypia or necrosis should be established for the exclusion of a malignancy. In the presence of massive lymphocytic infiltration of a leiomyoma the clonality of the infiltrate may aid in differentiating it from a malignant lymphoma. The pathogenesis and clinical significance of these rare neoplasms remain to be clarified.

RESUMEN

OBJECTIVE: To assess endogenous androgen and insulin resistance status in postmenopausal women receiving continuous combined hormone therapy (HT), tibolone, raloxifene or no therapy. METHODS: A total of 427 postmenopausal women aged 42-71 years were studied in a cross-sectional design. Among them 84 were taking HT (46 women conjugated equine estrogens 0.625 mg; medroxyprogesterone acetate, 5 mg, CEE/MPA; and 38 women 17beta-estradiol 2 mg; norethisterone acetate 1 mg, E2/NETA); 83 were taking tibolone 2.5 mg; 50 were taking raloxifene HCl 60 mg; and 210 women were not receiving any therapy. Main outcome measures were FSH, LH, estradiol, total testosterone, SHBG, free androgen index (FAI), Delta4-Androstendione (Delta4-A), Dehydroepiandrosterone sulphate (DHEAS) and HOMA insulin resistance index (HOMA-IR). RESULTS: In women not on hormone therapy smoking and older age was associated with lower DHEAS levels. FAI values increased linearly with increasing BMI. Age and BMI were positive determinants of HOMA-IR, while no association was identified between endogenous sex steroids and insulin resistance. CEE/MPA therapy was associated with higher SHBG, lower FAI and lower HOMA-IR values compared to women not on therapy (age and BMI-adjusted SHBG: CEE/MPA 148.8 nmol/l, controls 58.7 nmol/l, p < 0.01; age-adjusted FAI: CEE/MPA 0.8, controls 3.2, p < 0.05; age-adjusted HOMA-IR: CEE/MPA 1.3, controls 2.6, p < 0.05). On the contrary, E2/NETA treatment had no effect on these parameters. Women on tibolone had lower SHBG, higher FAI and similar HOMA-IR values compared to controls (age and BMI-adjusted SHBG: 24.1 nmol/l, p < 0.01; FAI: 6.0, p < 0.05; HOMA-IR: 2.3, p = NS). Raloxifene users did not exhibit any difference with respect to sex steroids and HOMA-IR levels. CONCLUSIONS: CEE/MPA users had lower free testosterone and improved insulin sensitivity. Tibolone on the other hand associated with higher free testosterone, while raloxifene did not relate to any of these parameters.

RESUMEN

OBJECTIVE: To present a new imaging technique for the evaluation of the functional effectiveness of Creatsas vaginoplasty. METHOD: Eighteen women with Mayer-Rokitansky-Kuster-Hauser syndrome underwent a transabdominal and transperineal ultrasound examination 4 weeks and 6 months after the surgical creation of a neovagina, and then yearly, with a condom filled with water as a distending and imaging medium. The functional length and width of the neovagina and its axis deviation were assessed, as well as the postoperative quality of the women's sexual life. RESULTS: A functional vagina 10 to 12 cm in length and 4 to 5 cm in width was observed; its axis deviation, which was similar to the anatomic deviation, was easily determined; and 94.5% of the women reported a satisfactory while 5.5% reported an adequate sexual life. CONCLUSION: This new imaging technique is a simple and effective alternative for the evaluation of the postoperative effectiveness of colpopoiesis.

RESUMEN

AIM: TPS concentrations were measured throughout normal pregnancy in maternal serum (MS) and amniotic fluid (AF), in order to evaluate the usefulness of TPS in the follow-up of pregnancy breast cancer patients. PATIENTS AND METHODS: Following informed consent, 30 pregnant women during the 2nd trimester, 28 during the 3rd and 26 at parturition were included in the study. For comparison, 28 women in the 1st trimester and 28 healthy, non pregnant women (controls) were also studied. Both MS and AF antigen values were measured by an enzyme immunoassay (BEKI Diagnostics). RESULTS: Maternal serum TPS concentrations increased significantly with gestational age (p < 0.0001), being significantly higher in the 3rd trimester and during labor than those in the controls (p < 0.0001). Amniotic fluid TPS values were markedly elevated, compared with those in MS (p < 0.0001, paired-t-test), declining significantly from the 2nd to the 3rd trimester (p < 0.0015) and labor. Both MS and AF TPS values during labor depended on the mode of delivery, being higher in the cases terminated by vaginal delivery, compared to those by elective cesarean section. CONCLUSION: Maternal serum TPS values are influenced significantly by pregnancy, and thus, this antigen, as tumor marker seems to be reliable only during early pregnancy.
