RESUMO

UNLABELLED: The purpose of this study was to investigate the of areas where the soil is contaminated by Toxocara ova and also to assess seroepidemiological positivity in a Greek pregnant women population (ELISA IgG test). MATERIALS AND METHODS: The authors carried out an examination of soil samples collected from different areas of Athens and Piraeus (Kazakos method). Blood serum was only collected from pregnant women living and conducting activities in places close to the places where the soil sample's were collected for at least a decade (ELISA IgG assay). RESULTS: The authors suggest a correlation between the positive response in the ELISA assay IgG antibodies and the activities of people where soil was contaminated by Toxocara eggs. In conclusion, the prevalence of Toxocara canis infection in a population of Greek pregnant women was found to be a rate of 17.16% and the soil contamination rate of 17.08%.

RESUMO

Women with polycystic ovary syndrome (PCOS) are often characterized by adiposity and insulin resistance (IR). Recent studies in patients with obesity and diabetes mellitus type 2 (DMt2) indicate that adiponectin and resistin may play a role in the pathophysiology of IR. The aim of this study was to identify a possible correlation between the plasma levels of adiponectin and resistin and IR in patients with PCOS. Thirty-one women of reproductive age were enrolled in this prospective study after being diagnosed with PCOS and IR according to Rotterdam and American Diabetes Association (ADA) criteria, respectively. Every patient was treated with a daily dose of 1275 mg metformin for 6 months. Adiponectin, resistin, and the primary hormonal and metabolic parameters of the syndrome were evaluated at entry and endpoint of treatment. Adiponectin plasma levels were reduced after metformin treatment, but resistin levels were not significantly affected. Our study suggests that circulating levels of adiponectin should be evaluated with skepticism in patients with PCOS. The adipokine's role in the manifestation of IR in PCOS remains unclear and needs further investigation.

RESUMO

OBJECTIVE: Recently, it has been debated whether the new polycystic ovary syndrome (PCOS) phenotypes, according to the Rotterdam criteria, share the same metabolic risk with the classic ones (National Institutes of Health 1990). Our study sought to compare the prevalence of metabolic syndrome (MS) and glucose homeostasis disorders in Greek women with classic and new PCOS phenotypes. MATERIALS AND METHODS: Two hundred and sixty-six Greek PCOS women were recruited and divided into groups according to two of the three Rotterdam criteria that they fulfilled. Two subgroups were formed; the first represented the classic phenotypes and the second the new phenotypes. The clinical, biochemical, and ultrasound characteristics of both groups were explored. All subjects were evaluated for MS and underwent a 2-h glucose tolerance test to assess insulin resistance (IR) as measured by the homeostasis model assessment (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and MATSUDA indices. RESULTS: 62.4% of PCOS women were classified as classic NIH phenotypes of which 32 women had MS (prevalence 19.6%). Only 4 patients categorized in the newer phenotypic groups had MS (prevalence 4.1%). Among the subjects with classic phenotypes, 11.7% exhibited impaired glucose tolerance (3-fold higher percentage compared to patients with newer phenotypes). Regarding IR indices, HOMA-IR was significantly higher and QUICKI significantly lower for classic phenotypes. CONCLUSIONS: Greek PCOS women with classic phenotypes are at increased risk for MS and impaired glucose homeostasis compared to women with newer phenotypes. A subclassification of PCOS permits the earlier recognition and closer surveillance of women whose metabolic profile indicates potential risks for adverse health outcomes.

RESUMO

BACKGROUND: Hormone therapy (HT) is the treatment of choice for the alleviation of menopausal symptoms; concerns, however, about its concomitant long-term health risks have limited its use. DT56a is a unique enzymatic isolate of soybeans. The purpose of our study was to evaluate the efficacy and safety of DT56a, compared to HT, in symptomatic post-menopausal women. SUBJECTS AND METHODS: Eighty-nine post-menopausal women were studied prospectively. Women with climacteric symptoms were randomly assigned to receive eitherDT56a (no.=27) or oral low dose continuous combined HT (no.=26). Symptomatic women not wishing to receive any treatment served as controls (no.=36). Menopausal symptoms as assessed through the Kupperman index, serum lipids and lipoproteins, calcium, as well as bone mineral density (BMD), endometrial thickness, and mammography were assessed at baseline and at 12 months. RESULTS: Patients receiving HT and DT56a showed a significant and independent decrease in menopausal symptoms (mean difference in Kupperman score, DT56a group: -3.98, HT group -5.601, no treatment group +1.76, p-value <0.001). Lumbar spine BMD T-score was significantly lower in women receiving no treatment, as opposed to the two treatment arms which showed no significant change (No treatment, baseline: -0.60, final: -0.85, p=0.001; HT, baseline: -84, final -0.99, p=0.79; DT56a, baseline -0.51, final: -0.76, p=0.75). No differences in femoral bone density, ET or mammography classification were detected in any of the treatment arms. Likewise, serum lipids or lipoproteins did not differ between the three groups. CONCLUSIONS: DT56a decreased menopausal symptoms significantly and in the same degree as HT.

RESUMO

AIM: To determine the prevalence and frequency of non classical congenital adrenal hyperplasia (NC-CAH) due to 21-OHD at the time of clinical presentation and at the peripubertal period in a substantial sample of Greek women with acne and to investigate the correlation of serum T, 17-OHP and DHEA-S with acne appearance at the time of clinical presentation. METHODS: One hundred and twenty-three unselected women with hyperandrogenemic symptoms were examined. After the ACTH stimulation test, 6 (4.9%) women were diagnosed with NC-CAH due to 21-OHD. RESULTS: There was not any statistical significant difference in the frequency of peripubertal acne between NC-CAH group of patients (6.4%) and patients with hyperandrogenemia of other aetiology (93%), mainly ovarian (P = 0.41). However, there was a statistical significant difference in the prevalence of acne at the time of clinical examination between the two groups (P = 0.04). Acne was present in 83.3% of women with NC-CAH vs. 41.02% of women in the hyperandrogenic group without NC-CAH. A statistically significant decrease of acne from the peripubertal time to the time of clinical examination in the group of women with hyperandrogenemia of other aetiology (-21.37%) was observed compared to women with NC-CAH (P < 0.001). CONCLUSION: We have shown that acne persists from peripubertal period to adult life in NC-CAH women whereas it tends to diminish in women with hyperandrogenemia of other aetiology. Acne is a prominent finding in women with NC-CAH. Serum concentrations of 17-OHP after ACTH stimulation (17-OHP6O ) should be investigated in women with persistent acne in adult life.

RESUMO

BACKGROUND: Since 2003, when the American Society for Reproductive Medicine (ASRM) and European Society of Human Reproduction and Embryology (ESHRE) sponsored consensus established criteria for polycystic ovarian syndrome (PCOS) diagnosis, the phenotypic spectrum of the syndrome has been significantly broadened. PURPOSE OF THE STUDY: This survey makes an effort to distinguish PCOS according to phenotypic expression and to estimate its prevalence in a Greek population. MATERIALS AND METHODS: Greek women from 18 to 35 years of age, who visited the outpatient department, claiming either irregular menstruation (oligo- or anovulation, OA) or clinical manifestations of hyperandrogenemia (HA) were recruited. They gave full disease history and underwent clinical examination, including transvaginal ultrasound (TVUS) scan to identify PCO morphology. Blood samples were collected to perform hormonal and metabolic analyses. Acute or chronic disorders were excluded. Finally, 266 PCOS women constituted the study population. CONCLUSIONS: The full-blown phenotype (HA+OA+PCO) is the predominant phenotype in this Greek population.

RESUMO

OBJECTIVE: To present a case of a young woman with ovarian endometrioid adenocarcinoma arising from an endometriotic cyst and review of the literature. CASE REPORT: A 33-year-old woman, gravid 2, para 2 was admitted to our department with a 5 cm adnexal mass. Diagnostic laparoscopy was performed and pathological examination demonstrated an endometriotic cyst with an area of an ovarian endometrioid adenocarcinoma well differentiated, with no capsular invasion. One month after the operation the patient underwent MRI which revealed a 6 cm mass in the Douglas pouch. The multidisciplinary oncology council decided on exploratory laparotomy, which revealed no pathology. After that the multidisciplinary oncology council decided on adjuvant chemotherapy and the patient received four cycles of carboplatin/taxol. CONCLUSION: It should always be considered that even when there are no risk factors for malignancy occurrence, a high index of suspicion is necessary and will help to prevent delay in the diagnosis of this rare neoplasm.

RESUMO

BACKGROUND: Women with polycystic ovary syndrome (PCOS) may have increased cortical bone mineral density (BMD) and probably higher bone material quality as well as better resistance in the compression strength of the tibia, measured by peripheral quantitative computed tomography (pQCT), in comparison with that of age-matched healthy subjects. METHODS: Thirty women with PCOS, (15 lean and 15 obese) and 15 age-matched healthy controls were enrolled in this study. The clinical, biochemical and ultrasound characteristics of the two groups were evaluated. Using pQCT, the following parameters were measured: volumetric cortical density (CBD) and volumetric trabecular density (TBD) BMD, total bone cross-sectional area (ToA), cortical area (CoA), cortical thickness (CRT-THK-C) and finally the strength-strain index (SSI). RESULTS: The geometrical parameters (CoA, ToA, CRT-THK-C), the SSI as well as the TBD were increased in the PCOS women; however, these differences did not achieve statistical significance between lean PCOS women, obese PCOS women, and controls. Conversely, CBD was significantly higher in PCOS women compared with controls (P < 0.000) and furthermore in lean PCOS women compared with obese ones (P < 0.01040). CONCLUSIONS: The PCOS women of our study seem to have a higher quality of bone material in the distal tibia and probably a better resistance of bone in the compression strength without alterations in bone mass and geometry (especially the lean PCOS women), indicating that our oligomenorrheic and hyperandrogonemic PCOS women may be protected from the development of osteoporosis and fracture risk later in life.

RESUMO

BACKGROUND: Radioactive iodine has been used effectively in the diagnosis and treatment of thyroid diseases. Since radiation is delivered to the whole body, including the ovaries, there is reasonable concern as to whether there is a possibility of mutagenic effect on germ cells. CASE REPORT: A 33-year-old woman with a differentiated papillary carcinoma. (T2N0M0), underwent radiotherapy three weeks after surgery and one year afterwards she became pregnant. At the 38th week of gestation she delivered vaginally a healthy female neonate weighing 3100 g. The child at the age of five years is healthy with no signs of malignancy or other disease. DISCUSSION: Washout of 131I of the whole body takes place in a few days. Nevertheless, most guidelines recommend avoiding pregnancy for four to six or even 12 months after RAI treatment or scanning. As reported in our case a normal uncomplicated pregnancy can follow an operative and complementary treatment of thyroid cancer.

RESUMO

Young, normotensive, and non-obese women with polycystic ovary syndrome (PCOS) may present abnormal hemodynamic alterations (HA). The purpose of this study was to investigate heart rate (HR), intima-media thickness (IMT), and diameter (DCCA) in the common carotid arteries (CCA), flow velocities, and resistance index in both extracranial carotid and vertebral arteries (VA), in the abdominal aorta (AO) and in the renal arteries (RA) in PCOS women and matched controls. This was a case-control study conducted at a tertiary University Hospital. We studied 53 PCOS women and 53 healthy matched volunteers as controls. The previously reported parameters were assessed using color Doppler ultrasonography. HR, IMT in the CCA, and peak systolic velocity in all examined arteries were significantly increased in PCOS women compared to controls. On the contrary, DCCA was significantly decreased in PCOS women compared to controls. End diastolic velocity (EDV) in both VA and RA, in the AO and in the left extracranial carotid system was significantly increased in the PCOS group compared to controls. Furthermore, the peripheral resistance (PR) of AO and right external carotid artery was also found to be increased while in both RA and in left VA, PR was decreased. No further statistical significant HA in EDV and PR were noted. The results of this study provide evidence for a mild hyperdynamic circulation in young, normotensive, non-obese women with PCOS compared to controls, indicating a mild sympathetic activation at an early age, which may be an underlying cause of hypertension and cardiovascular risk.

RESUMO

In young members of a large family from a Greek island with a closed society, clinical and hormonal symptoms of 21-OH deficiency (CAH) were present. To discriminate those affected from those unaffected, we measured the basal and ACTH stimulated 30 values of 17-hydroxyprogesterone (17-0HP) progesterone (P) and cortisol (F) in combination with HLA-phenotypes in 25 out of 40 members of this family. The indices of the Gutai30-min assessment (17-0HP+P response to ACTH testing at 30 min), GF (F response at 30 min) and the ratio GF30/Guai30 named the Marina index were evaluated. The Marina index showed a very statistically significant difference among the three groups (p < 0.001). HLA phenotypes of the members of groups A and B showed a powerful association with B14, DR1, B7, and B35 phenotypes that were related with 21-OH/CAH. In conclusion, in our study population, a high incidence of a clinically asymptomatic form of 21-OHdef was found only after the ACTH stimulation test. The Marina index seems to be of high diagnostic value in classifying disease severity.

RESUMO

We present two rare cases of successful full-term pregnancies in a young woman suffering from lupus erythematosus for two years, who had subfertility problems and two missed abortions, before and after the diagnosis of lupus, with assisted reproduction. She received 10 mg of prednisolone daily from ovulation induction (with recombinant FSH--50 IU) until delivery, together with acetylsalicylic acid from ovulation induction until the 37th week of gestation and finally progesterone in high doses from the last insemination until the 12th week of gestation.

RESUMO

BACKGROUND/OBJECTIVES: The aim of the study was to compare the effect of two-meal patterns (three vs six meals per day) on glucose and insulin levels in women with polycystic ovary syndrome (PCOS). SUBJECTS/METHODS: In a randomised, crossover, 24-week study, 40 women with PCOS, aged 27±6 years, body mass index 27±6 kg/m(2), followed a weight maintenance diet (% carbohydrates:protein:fat, 40:25:35), consumed either as a three- or a six-meal pattern, with each intervention lasting for 12 weeks. Anthropometric measurements, diet compliance and subjective hunger, satiety and desire to eat were assessed biweekly. All women underwent an oral glucose tolerance test (OGTT) with 75 g glucose for measurement of plasma glucose and insulin at the beginning and end of each intervention. HaemoglobinA1c (HbA1c), blood lipids and hepatic enzymes were measured at the beginning and end of each intervention. RESULTS: Body weight remained stable throughout the study. Six meals decreased significantly fasting insulin (P=0.014) and post-OGTT insulin sensitivity (Matsuda index, P=0.039) vs three meals. After incorporation of individual changes over time, with adjustment for potential confounders, the only variable that remained significant was the Matsuda index, which was then used in multivariate analysis and general linear models. Six meals improved post-OGTT insulin sensitivity independently of age and body weight vs three meals (P=0.012). No significant differences were found between six and three meals for glucose, HbA1c, blood lipids, hepatic enzymes, subjective desire to eat and satiety. CONCLUSIONS: Six meals had a more favourable effect on post-OGTT insulin sensitivity in women with PCOS compared with isocaloric three meals.

RESUMO

sIL-2R and NSE were measured in 24 patients with small cell carcinoma (NSCC) of the lung, in 25 patients with non small cell carcinoma (NSCC) and in 20 controls matched for age, sex and smoking habits. Significantly elevated values of sIL-2R and NSE were found in the SCC group (mean +/- SEM: 2103 +/- 314.4 U/ml and 44.5 +/- 7.3 ng/ml respectively), compared to those in the NSCC group (1079 +/- 104.5 U/ml and 3.64 +/- 0.8 ng/ml, p < 10(-7) respectively) and to controls (561 +/- 44.6 U/ml and 1.7 +/- 0.3 ng/ml p < 10(-5). In the SCC group, 83.3% of sIL-2R and 87.5% of NSE values were above cut-off (900 U/ml and 10 ng/ml respectively), while in the NSCC group, 48% of sIL-2R and only 8% of NSE values were above cut-off. In the controls, all values of both parameters were below cut-off. The results suggest that sIL-2R and NSE in concurrent measurements may help in decision making as regards treatment and prognosis.

RESUMO

BACKGROUND: Cytokines are considered as part of host defence to infection or injury. MATERIAL AND METHODS: Pretreatment values of TNF and sIL-2R were measured in 132 women with a) ovarian carcinoma (n = 25), b) breast cancer (n = 20), c) endometrial cancer (n = 15), d) cervical squamous cell carcinoma (n = 19), e) cervical adenocarcinoma (n = 11) and f) benign gynecological diseases (n = 42) in order to evaluate whether these cytokines could be useful in the discrimination of malignant from benign gynecological diseases. RESULTS: Both TNF and sIL-2R were significantly higher in all cancer groups together (mean +/- SD: 30 +/- 11 pg/mL and 1293 +/- 465 U/mL respectively), than those in the benign group (16.0 +/- 6 pg/mL and 626 +/- 233 U/mL, respectively; p < 0.0001), while no significant differences were found for TNF and sIL-2R values in the five cancer groups. Significantly higher cytokine values were measured in the advanced stage diseases (33 +/- 11 pg/mL and 1705 +/- 192 U/mL), than those in the limited cancer (26 +/- 12 pg/mL, p < 0.05 and 916(521 U/mL, p < 0.0001). CONCLUSIONS: Our results suggest that, cytokines may be useful in the discrimination of malignant from benign gynecological diseases and in monitoring tumor activity in patients early in the malignancy process.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate thyroid function and TSH and cortisol (F) secretion in hyperandrogenemic women with nonclassical congenital adrenal hyperplasia (NC-CAH) due to 21-hydroxylase deficiency (Group A) when compared with women with hyperandrogenemic symptoms (menstrual irregularities, hirsutism, acne, seborrhea and sterility) of other etiologies (Group B). METHODS: Seventy-two women were subjected to stimulation of the adrenal cortex with i.v. ACTH administration in the early proliferative phase of the menstrual cycle. Basal plasma TSH, T3, T4, and FTI as well as basal and ACTH-stimulated plasma F and 17-hydroxyprogesterone levels were determined. RESULTS: According to internationally accepted criteria and HLA haplotyping, we diagnosed 28 NC-CAH patients as well as affected heterozygotes of the disease. No significant difference was found in the plasma T3, T4, or FTI or F concentrations between the women of the two groups. On the contrary, plasma TSH levels were significantly lower in patients with 21-hydroxylase deficiency when compared to the women with hyperandrogenemic symptoms of other etiologies. CONCLUSION: The results of this study support a dysfunction of the hypothalamic-pituitary-thyroidal axis due to altered ACTH secretion patterns.

RESUMO

Pretreatment values of CEA, CA125, SCC and TPS were measured in 130 women with 1) ovarian carcinoma (n = 25), 2) breast cancer (n = 20), 3) endometrial cancer (n = 14), 4) cervical squamous cell carcinoma (n = 20), 5) cervical adenocarcinoma (n = 9) and 6) benign gynaecological diseases (n = 42) in order to evaluate the usefulness of multiple markers in diagnosing and monitoring patients with gynaecological cancer. Antigen values were significantly higher in the cancer groups than those in the benign one (p < 0.0001). CEA values were significantly elevated in the 2nd and 5th groups, CA125 in the 1st and 5th, SCC in the 4th and 5th, and TPS in the 1st, 2nd and 5th compared to the remaining groups (p < 0.04-p < 0.0001). In advanced stage diseases, significantly higher antigen values, except for SCC, than those in limited tumours were measured (p < 0.05-p < 0.0001). In conclusion, our results suggest that, multiple markers may be more efficient than the use of single markers in accurately identifying malignant from benign gynaecological diseases and in monitoring cancer patients.

RESUMO

Congenital adrenal hyperplasia due to deficiency of the enzyme 21-hydroxylase (21-OH), a cytochrome P450 enzyme located in the endoplasmic reticulum and which catalyzes the conversion of 17-hydroxyprogesterone to 11-deoxycortisol and progestene to deoxycorticosterone, is distinguished in its classical and non-classical form and is also one of the most common autosomal recessive inherited diseases in humans. The classical form appears in a rate between 1:5000 and 1:15,000 among the live neonates of North America and Europe, while the non-classical form occurs in approximately 0.2% of the general white population. This rate is especially high between the Ahskenazi Jews and a part (ie Italians, Hispanics) of the Mediterranean populations. Three alleles are associated with the 21-OH locus and can be combined in several ways in individuals who are either unaffected, heterozygote carriers, or affected with classical or non-classical disease. Variable signs and symptoms of hyperandrogenism, such as hirsutism, acne, virilization of the external genitalia and/or the body, short stature, menstrual irregularities, are common to both types of the disorder. Among the genes responsible for the synthesis of the enzyme 21-OH and the antigens of HLA system, exist both a proven genetic linkage and a proven genetic linkage disequilibrium. HLA-Bw47, HLAB5 and HLA-B35 are the most common haplotypes usually met in the classical form, while the haplotype HLA-B14DR1 is the most recurrent in the non-classical form of the disease. The significant advances in molecular biology and gene analysis over the past two decades have led to the development of novel sensitive methods of DNA analysis and study, such as polymerase chain reaction and southern blot analysis. Thus, it has been revealed that the synthesis of enzyme 21-OH is controlled by two genes, the active CYP21B gene and the CYP21A pseudogene. All three forms of the disease have a known sequence of gene changes owing to mutations in isolated proteins or whole series of genes due to translocations or deletions of genetic material.
