ABSTRACT

OBJECTIVE: Human leukocyte antigen-DR (HLA-DR) has been implicated in eutopic and ectopic glandular epithelial cells in endometriosis. We investigated the expression of HLA-DR in endometriotic and adenomyotic tissues within the stromal and glandular cells. Moreover, we correlate the HLA-DR expression according the transvaginal ultrasonography findings. METHODS: We studied operative and pathologic reports of 113 women who underwent laparoscopic or laparotomy treatment of endometrioma or adenomyosis. Tissues from 51 women with endometrioma and 62 women with adenomyosis were retrospectively evaluated. The distribution and intensity of the HLA-DR immunostaining was assessed using electron microscopy. Pathologic finding of the uterine junction zone and the size of endometrioma were evaluated with the laparoscopic results and the ultrasound findings. RESULTS: In adenomyosis tissues, the percentage of HLA-DR cells expression was significantly higher in stromal cells (83.9%) compared to glandular cells (25.8%), (p<0.001). The number of HLA-DR-positive endometriotic glandular cells was significantly higher than the total glandular adenomyotic cells (p<0.005). HLA-DR-positive cells was significantly different between stromal (p<0.016) and glandular cells (p<0.044) in each side of endometrioma. Finally, HLA-DR-positive percentage cells were significantly more frequent in the secretory phase than the proliferative in stromal and glandular cells in both groups. CONCLUSION: HLA-DR antigen expression in endometrium and adenomyotic tissues. However, HLA-DR expression is distributed preferentially in glandular epithelial cells in endometrioma and in the adenomyotic stroma. In both groups the HLA-DR expression was significantly higher in the secretory phase than the proliferative or glandular and stroma cells. Larger perspective studies are needed to establish the expression of HLA antigens in immune reactions which occur in adenomyosis and endometriosis.

ABSTRACT

OBJECTIVE: To evaluate the concentrations of human placental growth hormone (hPGH) in amniotic fluid (AF) at gestational mid-trimester in normal pregnancies and in pregnancies complicated by Down's syndrome. DESIGN: AF samples from 21 women with Down's syndrome pregnancies were analyzed retrospectively. About 47 AF samples from women with singleton, uncomplicated pregnancies, who gave birth to healthy neonates with birth weight appropriate for gestational age were used as controls. All AF samples were obtained during amniocentesis for fetal karyotyping at 16-23 weeks' gestation. hPGH levels were measured by a solid phase immunoradiometric assay using two different epitopes. RESULTS: The mean hPGH values in the AF of the Down's syndrome-affected pregnancies were significantly higher (P<0.05) compared to those of normal pregnancies, at 16-23 weeks' gestation: mean-value+/-SD in the AF was 1.96+/-1.35 microg/l vs. 0.82+/-0.67 microg/l. CONCLUSIONS: Higher hPGH levels in AF were found in pregnancies affected by Down's syndrome as compared to normal pregnancies at gestational mid-trimester. hPGH was detected in all AF samples, and it provides evidence that this pregnancy-specific hormone enters the fetal compartment and is not limited to the maternal circulation. The physiological role and effect of hPGH on fetal growth in normal and pathological pregnancies needs further investigation.

ABSTRACT

We report a case of trisomy 21 mosaicism detected upon amniocentesis in a 36-year-old woman. Ultrasound examination at 23 weeks' gestation showed a fetus with hydrops, pulmonary hypoplasia, oligohydramnios, thickened placenta, and intrauterine growth retardation. Cytogenetic analysis revealed low-percentage (6%) mosaicism for trisomy 21. Hydrops fetalis and thickened placenta are uncommon findings in fetuses affected by trisomy 21 mosaicism. A short review of the literature is given regarding the sonographic findings associated with trisomy 21 mosaicism, and the genetic counseling in such cases.

ABSTRACT

Amniotic band syndrome is an uncommon, congenital fetal abnormality with multiple disfiguring and disabling manifestations. A wide spectrum of clinical deformities are encountered and range from simple ring constrictions to major craniofacial and visceral defects. We report a case of constriction amniotic bands involving upper extremities and intrauterine fetal death due to strangulation of umbilical cord. Abnormally elevated levels of alpha-fetoprotein and beta-chorionic gonadotropin were detected at 17 weeks' gestation. They were probably caused by the loss of cutaneous integrity of the fetus (alpha-fetoprotein), and by the placental attempt to counteract the fetal growth restriction and hypoxia, due to the strangulation of umbilical cord by the amniotic bands (beta-chorionic gonadotropin).

ABSTRACT

Medically assisted human reproduction is a controversial issue that has attracted heated debate over the last two decades. In December 2002 the Greek Parliament passed a law with major social and scientific impact: the Medically Assisted Human Reproduction Act 3089/02. This law establishes the parameters of so-called surrogate motherhood, protects the anonymity of semen donors and sets the legal framework through which a woman's artificial fertilization after her husband's death is allowed. This article aims to discuss the legal ramifications of medically assisted human reproduction and especially the moral and social issues concerning the introduction of surrogate motherhood in Greece.

ABSTRACT

Dilatation of the fetal umbilical vein is a rare, most commonly isolated finding. Approximately 100 cases have been reported in the literature that describe different management approaches, especially regarding the time of delivery. We present a new case of umbilical vein dilatation diagnosed at 23 weeks' gestation as an isolated sonographic finding, in a fetus with short umbilical cord, delivered at 38 weeks' gestation. The clinical and sonographic features as well as the management options of this uncommon condition are shortly discussed.

ABSTRACT

OBJECTIVE: The aim of this randomized study was to compare the effectiveness, safety, and side effects of 6 h vaginal misoprostol versus vaginal prostaglandin E(2) (PGE(2)) for labor induction. STUDY DESIGN: Fifty microgram of misoprostol was given intravaginally in the misoprostol group (204 women), and 3 mg PGE(2) was given intravaginally in the PGE(2) group (211 women). In both groups, the dose was repeated every 6 h for a maximum of three doses, until active labor was achieved. Artificial rupture of membranes and oxytocin infusion was used during labor in both groups where it was indicated. RESULTS: The mean interval from the institution of labor induction to delivery was 11.3 +/- 8.6 h for the misoprostol group, and 15.7 +/- 9.3 h for PGE(2 )group (P < 0.05). In the misoprostol group, oxytocin was used less frequently, but there was a higher prevalence of tachysystole. No statistically significant differences were observed between the two groups as regard abnormal patterns of fetal heart rate, the mode of delivery, and the need for neonatal intervention. CONCLUSION: In conclusion, the intravaginal administration of 50 mug misoprostol at 6 h interval (maximum three doses) is comparable in safety, but more effective for induction of labor than 3 mg intravaginal PGE(2).

ABSTRACT

Anencephaly is a rare congenital anomaly in which the forebrain, meninges, vault of the skull, and scalp all fail to form. We report a case of a 32-year-old gravida 2 woman with an anencephalic fetus detected at the 21st gestational week. She had a history of an intrauterine fetal death of an anencephalic fetus at the 20th gestational week two years before. We present the case and briefly review the literature.

ABSTRACT

OBJECTIVE: To evaluate the relationship between maternal serum and amniotic fluid levels of human Placental Growth Hormone (hPGH) with the fetal intrauterine growth retardation (IUGR) related to preeclampsia. DESIGN: We analyzed samples in pairs of serum and amniotic fluid retrospectively from 25 women, who manifested preeclampsia and IUGR in the late second or the third trimester of gestation. The samples were obtained at 16-22 weeks' gestation during amniocentesis for fetal karyotyping. At this time, there was no clinical or sonographic evidence of preeclampsia or IUGR, respectively. Sixty-two serum samples were used as controls which were obtained at 16-22 weeks' gestation from women with singleton, uncomplicated pregnancies, with normal outcome, and appropriate for gestational age neonatal birth weight. Forty-seven amniotic fluid samples were also used as controls which were obtained at 16-22 weeks' gestation from the women that were included in the control group who underwent an amniocentesis. hPGH levels were measured by a solid phase immunoradiometric assay. RESULTS: The mean hPGH values in the serum and the amniotic fluid of the IUGR related to preeclampsia affected pregnancies were significantly higher (P<0.05) than those of the normal pregnancies at 16-22 weeks' gestation: mean+/-SD in the serum was 13.16+/-10.52 ng/ml vs. 4.39+/-2.23 ng/ml; mean+/-SD in the amniotic fluid 2.49+/-1.6 ng/ml vs. 0.82+/-0.67 ng/ml. CONCLUSION: hPGH levels in maternal serum and amniotic fluid were found to be higher at 16-22 weeks' gestation in pregnancies that will be complicated subsequently by IUGR related to preeclampsia. Our findings suggest that the evaluation of the changes of hPGH levels at midtrimester should be further investigated for the possibility to provide a potential predictive index of IUGR and preeclampsia.

ABSTRACT

Hypochondroplasia (HCH) is an autosomal dominant skeletal dysplasia characterized by short extremities, short stature and lumbar lordosis, usually exhibiting a phenotype similar to but milder than achondroplasia (ACH). Mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are present in a significant proportion of HCH patients. Reports of prenatal diagnosis of HCH are very rare and the phenotype/genotype correlation in these patients is poor. Here we present two sporadic cases with second trimester ultrasound findings consistent with a diagnosis of a non-lethal skeletal dysplasia. Ultrasound evaluation after 23 weeks of gestation showed a decreased rate of development of the femora (femur length

ABSTRACT

BACKGROUND: Vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), transforming growth factor-beta1 (TGF-beta1), endothelin-1 (ET-1) and soluble c-kit ligand (sKL) are cytokines involved in embryogenesis. MATERIALS AND METHODS: Maternal plasma cytokines were measured with ELISA during the three trimesters of gestation and on the day of delivery in 93 pregnant women and 18 age-matched non-pregnant control women. RESULTS: The VEGF and bFGF levels increased during the first trimester and declined thereafter, but they remained above the controls' values until delivery. The TGF-beta1 levels increased during the first trimester and remained unchanged thereafter. On the contrary, the ET-1 levels decreased and remained low until delivery. VEGF, bFGF, TGF-beta1 and ET-1 were increased in hypertensive pregnancy. Except for ET-1, these cytokines were also increased in gestational diabetes. No changes in plasma sKL were documented. CONCLUSION: All the aforementioned cytokines play a role in uncomplicated pregnancy, whereas hypertensive pregnancy is causatively-related with increased ET-1.

ABSTRACT

The aim of this study was to evaluate the efficacy and tolerability of iron protein succinylate in the treatment of iron-deficiency anemia in pregnancy. One hundred and thirty anemic pregnant women were studied. Inclusion criteria were iron-deficiency type of anemia, and hemoglobin levels below of 11.5, 10.9 and 10.3 g/dl for the three trimesters of pregnancy, respectively. Twenty-five women who presented pregnancy-related complications were excluded during treatment. The remaining 105 were treated with 1600-mg iron protein succinylate per os daily for a period of four months. A group of anemia-related clinical signs and symptoms, and hematological parameters were recorded at the beginning of treatment, as well as two and four months later. They included epidermis and mucosal paleness, skin and nail lesions, glossitis, heart pulse, sickness, anorexia, apathy, ataxia, polypnea, insomnia, nervousness, paresthesias and other neurological symptoms; the hematological parameters included Hgb, hct, RBCs, WBCs, MCV, MCH, MCHC, PLTs, serum Fe and ferritin. Possible side or adverse effects were considered during treatment. The majority of symptoms and signs of anemia were gradually improved. There was a statistically significant increase in the means of Hgb, hct, WBCs, MCV, MCH, PLTs and serum ferritin (p < 0.05). Anemia was effectively treated in 100/105 (95.2%) women, but not in five patients (4.8%) who displayed poor compliance to the therapeutic protocol. There were transient and mild side-effects in seven (6.6%) treated women, namely diarrhea, epigastralgia, vomiting, and nausea, which however, did not necessitate discontinuation of the therapeutic protocol. Iron protein succinylate is an effective and well tolerated treatment of iron-deficiency anemia in pregnancy.

ABSTRACT

Perimenopause marks the transition from normal ovulation to anovulation and ultimately to permanent loss of ovarian function. Fecundity, the average monthly probability of conception, declines by half as early as the mid-forties, however women during the perimenopause still need effective contraception. Issues arising at this period such as menstrual cycle abnormalities, vasomotor instability, the need for osteoporosis and cardiovascular disease prevention, as well as the increased risk of gynecological cancer, should be taken into consideration before the initiation of a specific method of contraception. Various contraceptive options may be offered to perimenopausal women, including oral contraceptives, tubal ligation, intrauterine devices, barrier methods, hormonal injectables and implants. Recently, new methods of contraception have been introduced presenting high efficacy rates and minor side-effects, such as the monthly injectable system, the contraceptive vaginal ring and the transdermal contraceptive system. However, these new methods have to be further tested in perimenopausal women, and more definite data are required to confirm their advantages as effective contraceptive alternatives in this specific age group. The use of the various contraceptive methods during perimenopause holds special benefits and risks that should be carefully balanced, after a thorough consultation and according to each woman's contraceptive needs.

ABSTRACT

During the past decade, accumulated evidence indicates an association between endometriosis and an alteration of humoral and cell-mediated immunity. While the role of L-carnitine in the regulation of energy metabolism is well established, it is only recently that L-carnitine has been recognized to modify the immune response in mice after in vitro or in vivo treatment. The present study has examined whether administration of L-carnitine to young female mice alters the percentage of immune cells in peritoneal exudates and the uterus as well as the levels of IFN-gamma, TNF-alpha, IL-2, IL-4, IL-6, VEGF, GM-CSF and IGF-I in blood serum, peritoneal fluid and supernatants of uterine cultured cells as tested by immunofluorescence or ELISA techniques, respectively, leading to a pathological disorder resembling human endometriosis. The results showed that, except from infertility, L-carnitine treatment resulted in a significant increase of macrophages and to a lesser degree an increase of T-cells, while elevated levels of IFN-gamma and TNF-alpha were detected in both serum and peritoneal fluid compared to controls. Although levels of L-carnitine measured in mouse serum samples using a radioisotopic method showed an increase as compared to controls, levels of acyl-L-carnitine measured in the murine peritoneal fluid samples showed a decrease similar to that measured in peritoneal fluid samples from patients with endometriosis in stage IV of the disease. These results indicate that L-carnitine administration to female mice alters the cellular and growth factor profile in the uterus and peritoneum towards a phenotypical pathology similar to that of clinical endometriosis.

ABSTRACT

The present study reports about the effect of doxycycline and/or metronidazole on colonization by Candida organisms of the human gastrointestinal (GI), oropharyngeal tract and vagina. Treatment with doxycycline or metronidazole for 10 days increased, but not significantly, the GI, oropharyngeal or vaginal colonization by Candida species. The combination of doxycycline and metronidazole, used for the same period, caused a significant increase of 2.5 log10 CFU/g of stools (mean) colonization by Candida. Likewise, 2 out of 9 patients treated with the combination had substantially increased colonization of their vagina by Candida species. This effect, however, could not be expressed statistically due to the semiquantitative nature of the vaginal cultures. In contrast, the combination did not increase oropharyngeal colonization. In conclusion, doxycycline and metronidazole as monotherapies, did not increase significantly Candida colonization in the cavities examined. The combination of doxycycline and metronidazole had a substantial effect, increasing the GI and vaginal colonization by Candida organisms.

ABSTRACT

INTRODUCTION: Struma ovarii is a type of mature ovarian teratoma consisting mainly of thyroid tissue. The rarity of this tumor in pregnancy and the risk of malignancy make difficult the diagnosis and the management. CASE REPORT: We report a case of benign struma ovarii initially detected as an ovarian mass at the first trimester of pregnancy.

ABSTRACT

Endometriosis is a common gynecologic syndrome of unknown etiology and pathogenesis. Growth factors and inflammatory mediators produced by peritoneal leukocytes have recently been postulated to participate in the pathogenesis of endometriosis. Angiogenic factors released from peritoneal macrophages may also play a role in the development of this disease. In the present study, we investigate the soluble levels of vascular endothelial growth factor (VEGF), epidermal growth factor-receptor (EGF-R), granulocyte/macrophage-colony stimulating factor (GM-CSF), Insulin-like growth factor-1 (IGF-1) and interferon-gamma (IFN-gamma) in the serum of 28 women with and 20 without endometriosis. We also compared these levels before, during and after treatment with danazol and leuprorelin acetate depot, the two therapeutic regiments of choice concerning this disease. We found that only sVEGF levels were higher in women with endometriosis in comparison to controls (P < 0.001) while sEGF-R is not present. GM-CSF, IGF-1 and IFN-gamma soluble levels are not affected in either healthy or endometriotic subjects. The 6-month treatment with danazol decreased sVEGF levels (P < 0.02) and increased sEGF-R levels (P < 0.001). These observations support the view that VEGF may be associated with the disease process and that danazol may bring sVEGF levels to a normal threshold. However, future studies will be focused on the anti-angiogenic control of the action of VEGF in patients with endometriosis.

ABSTRACT

Placentally derived CRH seems to play a major role in the mechanisms controlling human pregnancy and parturition, via activation of specific receptors widespread in reproductive tissues. In the human placenta, CRH seems to modulate vasodilation, prostaglandin production, and ACTH secretion. It has also been suggested that CRH might act as a placental clock, determining the length of gestation. In addition, maternal plasma CRH concentrations are further elevated in pregnancies associated with abnormal placental function, such as preeclampsia and intrauterine growth retardation (IUGR). In this study, we sought to investigate the expression of CRH-R1 alpha levels in placentas from women who have undergone normal deliveries (control group) and patients who have been diagnosed as having preeclampsia or IUGR. Results showed that placental CRH-R1 alpha mRNA levels (as shown by quantitative RT-PCR) and protein levels (shown by Western blotting analysis) were significantly (P < 0.05) reduced in all of the complicated pregnancies. In contrast, levels of the angiotensin II receptor were elevated in preeclampsia and reduced in IUGR subjects, as shown by RT-PCR and Western blotting analysis. These findings might suggest that changes in receptor expression may contribute toward dysregulation of the dynamic balance controlling vascular resistance.

ABSTRACT

Ultrashort infrared laser pulses were transmitted through excised female breast tissue. The resulted signal was recorded by a streak camera with a time resolution of the order of a few ps. Experimental data of the temporal spread of the ultrashort pulse during the transmission through the tissue have been analyzed using the Patterson analytical expression derived from the diffusion theory. This resulted in the calculation of the absorption and reduced scattering coefficients, which are related to the optical characteristics of each type of tissue. The goal of the study was to use the theoretical values of the coefficients to discriminate different kinds of tissue.
