RESUMEN

BACKGROUND: Laminin-1 and matrix metalloproteinase (MMP)-9 may play roles in the progression from benign to malignant endometrium, so we aimed to investigate their levels of expression in these tissues. METHODS: This case-control study was conducted at a tertiary care center between January 2014 and December 2016. Paraffin blocks of 50 specimens of benign endometrium with proliferative (n = 20), secretory (n = 11), and atrophic (n = 5) endometrium; simple endometrial hyperplasia without atypia (n = 12); and endometrial polyp (n = 2) histology and 49 specimens of malignant endometrium with endometrioid (n = 40), serous (n = 7), clear cell (n = 1), and undifferentiated (n = 1) types were immunostained with laminin-1 and MMP-9 antibodies and assessed for basement membrane continuity for laminin-1 and the percentage and intensity of MMP-9 expression in epithelial cytoplasm. RESULTS: : Laminin-1 continuity in the basement membrane was higher in benign (92%) compared to malignant (16.3%) endometrium (p < 0.0001) without any difference between the subgroups within each group (p > 0.05). All atrophic endometria and endometrial polyps and 23.5% of low grade endometrioid and none of the other endometrial cancers showed uninterrupted basement membrane staining with laminin-1. All cases in malignant endometrium expressed MMP-9 with either low or high immunoreactivity while none of the cases in benign endometrium showed a high staining with MMP-9 (p < 0.01). Proliferative and hyperplastic endometrium together with grade 1 endometrioid cancer expressed MMP-9 better than the atrophic endometrium (p < 0.05). The immunoreactivity with MMP-9 increased gradually from secretory to hyperplastic endometrium and serous carcinoma (p < 0.05). MMP-9 expression in all types of cancers except grade 1 endometrioid and clear cell compared to proliferative endometrium was significantly higher (p < 0.05) and increased from proliferative to grade 2 endometrioid, grade 3 endometrioid, serous and undifferentiated endometrial carcinoma. DISCUSSION: Gradual increments in MMP-9 expression and basement membrane laminin-1 discontinuity may indicate progression from normal to hyperplastic and to low- and high-grade cancerous endometrium.

RESUMEN

BACKGROUND: Milk fat globule-epidermal growth factor 8 (MFG-E8) is expressed in the endometrial epithelium and its expression increases during the implantation process. Due to this knowledge, we aimed to investigate the maternal serum MFG-E8 levels on both healthy pregnant women in the first trimester and pregnant women complicated with missed abortion and threatened abortion in the first trimester. METHODS: This prospective, cross-sectional study was conducted in a tertiary referral hospital, department of obstetrics between July 2020 and February 2021 after ethical committee approval. The study population was consisted of 30 healthy pregnant women (HP) in the first trimester, 30 pregnant women suffering from threatened abortion (TA) in the first trimester and 30 pregnant women suffering from missed abortion (MA) in the first trimester. Maternal serum MFG-E8 levels were analyzed with enzyme linked immunosorbent assay. Delivery and neonatal outcomes of the study population was evaluated. The continuous variables were compared among three groups with variance analysis with post hoc tests. The categorical variables were compared with chi-square and Fisher's exact tests where applicable. RESULTS: The mean age of the study population was 29.36 ± 5.31 years. There was no significant difference among three groups for parameters of age, body mass index, parity number, and gestational week. Despite being within normal ranges, the mean neutrophil and international normalized ratio values of the three groups showed statistically significant difference (p < 0.05). The mean maternal serum MFG-E8 levels of MA, TA, and HP groups were 270 ± 152.3, 414.7 ± 236.7, and 474 ± 222.5 ng/mL, respectively (p = 0.001). It was found that mean of MFG-E8 of the MA group was statistically significantly lower than those of the other two groups (p < 0.05). DISCUSSION: Although maternal serum MFG-E8 level seems to be a parameter that differ between live and nonlive pregnancies, studies with large number of cases are needed to discuss our results and to determine a cut-off value for prediction.

RESUMEN

Laminin receptor 1 may have a role in the progression from endometrial hyperplasia with or without atypia to endometrial cancer. Therefore, we aimed to investigate the pattern, percentage, and intensity of laminin receptor 1 expression in normal, hyperplastic, and neoplastic endometrium. Paraffin blocks of 131 specimens with the diagnoses of normal endometrium (n=25), endometrial hyperplasia with atypia (n=21) or without atypia (n=55), and endometrial cancer (n=30) were immunostained with laminin receptor 1 antibody, and its expression percentage, pattern, and intensity in the epithelial cytoplasm, basement membrane, and endometrial stroma of these tissues were assessed. When compared with hyperplasia with or without atypia and endometrial cancer, the percentage of nonstaining with laminin receptor 1 in the epithelial basement membrane was higher (96%), and the percentage of <50% staining with laminin receptor 1 was lower (4%) in the normal endometrium (P=0.001). While a progressive increment in staining percentage and density of epithelial cytoplasm and basement membrane was noted through an orderly progression from normal endometrium to endometrial hyperplasia without atypia, endometrial hyperplasia with atypia, and cancer of endometrium (P<0.001), such a relationship was not found for the staining percentage and density of endometrial stroma (P>0.05). Disease progression-related gradual increment in laminin receptor 1 expression in the epithelial basement membranes of hyperplastic endometrium with or without atypia and cancer of endometrium reveals that it may play a substantial role in the transition from premalignant to the malignant state of endometrial lesions.

RESUMEN

AIM: To compare maternal, fetal and placental trace element (magnesium, zinc and copper) and heavy metal (cadmium and lead) and maternal vitamin (retinol, α [alpha]-tocopherol, vitamin D3 , 25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3 ) levels in preterm deliveries with and without preterm premature rupture of membranes (PPROM). METHODS: Sixty-eight patients giving birth preterm were grouped into preterm deliveries with PPROM (n = 35) and without PPROM (n = 33). Following delivery, maternal and umbilical cord blood sera and placental tissue samples were obtained. While magnesium, zinc, copper, cadmium and lead levels were measured in all samples, the levels of retinol, α-tocopherol, vitamin D3 , 25-hydroxyvitamin D3 and 1,25-dihydroxyvitamin D3 were measured only in maternal serum. RESULTS: While magnesium level in maternal serum and zinc levels in both maternal and umbilical cord sera were lower, placental magnesium level was higher in preterm deliveries with PPROM (P < 0.01). Umbilical cord serum magnesium, placental tissue zinc and maternal and umbilical cord sera and placental tissue copper, cadmium, and lead levels did not differ between the groups (P > 0.05). In preterm deliveries with PPROM, 25-hydroxyvitamin D3 and retinol levels were higher, while vitamin D3 and 1,25-dihydroxyvitamin D3 levels were lower in maternal serum (P < 0.05). Maternal serum α-tocopherol levels were similar between the groups. CONCLUSION: Compared to spontaneous preterm births, PPROM is associated with low maternal serum together with high placental tissue magnesium and low maternal and umbilical cord sera zinc levels. Higher retinol and 25-hydroxyvitamin D3 and lower vitamin D3 and 1,25-dihydroxyvitamin D3 maternal serum levels are also evident in these patients.

RESUMEN

The aims of this prospective study were to detect maternal serum chemerin level in patients with preeclampsia and investigate its association with disease severity and neonatal outcomes. Maternal serum chemerin levels were significantly elevated in severe preeclamptic women (394.72 ± 100.01 ng/ml) compared to mild preeclamptic women (322.11 ± 37.60 ng/ml) and healthy pregnant women (199.96 ± 28.05 ng/ml) (p = .001). Maternal serum chemerin levels were positively correlated with systolic and diastolic blood pressure, C-reactive protein levels, homeostasis model assessment of insulin resistance, proteinuria, AST, ALT, and duration of hospitalisation. Gestational week at delivery, birthweight, and APGAR scores at 1 and 5 min were negatively correlated with maternal serum chemerin level. A maternal serum chemerin level of >252.0 ng/ml indicated preeclampsia with 95.5% sensitivity and 95.7% specificity. There was a positive correlation between maternal serum chemerin level and severity of preeclampsia. Additionally, adverse neonatal outcomes were significantly associated with high maternal serum chemerin levels.

RESUMEN

BACKGROUND The purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds. MATERIAL AND METHODS Forty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8000 Hz) and extended high (EH) (9000-20000 Hz) frequency audiometry. The fasting plasma glucose, insulin, FSH, LH, total testosterone, and sex hormone-binding globulin were measured in all patients. RESULTS The mean hearing thresholds at EH frequencies were statistically significantly higher in the PCOS group than in the control group (p=0.001 right ear and p=0.015 left ear). There were significant positive correlations among free testosterone index (FTI) values and hirsutism scores with EH frequency hearing thresholds. CONCLUSIONS At pure-tone audiometry (PTA) EH frequencies, we detected significantly higher hearing thresholds in PCOS patients than in controls. We also determined that elevated FTI and hirsutism score were positively correlated with elevated hearing thresholds in EH frequencies. These findings support that hyperandrogenism can play a role in the elevation of hearing thresholds in PCOS.

RESUMEN

PURPOSE: To compare the clinical and perinatal outcomes in eclamptic women with and without posterior reversible encephalopathy syndrome (PRES). METHODS: This single-center, retrospective, cohort study was conducted between 2008 and 2013. The clinical and perinatal outcomes of eclamptic patients were obtained from hospital records. Magnetic resonance imaging was used for the diagnosis of PRES. Eighty-one eclamptic women were divided into two groups: 45 and 36 patients were included in the PRES and non-PRES groups, respectively. RESULTS: In the PRES group, headache and visual impairment together (60.0 %) were the most common presenting symptoms. In the non-PRES group, only headache was the most common (50 %) presenting symptom. Occipital and parietal lobes were the most frequently affected areas in the PRES group. Women in the PRES group had a higher body mass index value (p = 0.005), longer hospitalization time (p = 0.001), and higher level of proteinuria (p = 0.012) than those in the non-PRES group. Women in the non-PRES group had higher Apgar scores (p = 0.002) than those in the PRES group. CONCLUSIONS: This study indicates that PRES manifests predominantly with headache and visual impairment together. Adverse neonatal outcomes are also common in these patients.

RESUMEN

Obesity is a substantial public health problem with a rapidly increasing prevalence in numerous industrialized nations. The objective of this study was to evaluate the effects of maternal pre-pregnancy obesity on fetal cardiac functions. We studied 55 fetuses of obese mothers and 44 fetuses of healthy mothers at 26-38 weeks of gestation. Cardiac functions were evaluated by M-mode, pulsed-wave, and tissue Doppler echocardiography. The two groups were similar in terms of maternal age, gravidity, parity, gestational age, estimated birth weight, serum lipids, and systolic-diastolic blood pressure. Fetal heart rate, diameters of the aortic and pulmonary valve annulus, aortic and pulmonary peak systolic velocities, ventricular systolic function, and cardiothoracic ratio were similar in the two groups. Pulsed-wave Doppler-derived E/A ratios in the mitral and tricuspid valves were similar in the two groups. The deceleration time of early mitral inflow was prolonged in the fetuses of the obese mothers. In the interventricular septum, left ventricle posterior wall, and right ventricle free wall, the E a and A a were higher, and E a/A a ratios were significantly lower in the study group than in the control group. The E/E a ratio was higher in the obese group than in the control group. The isovolumic relaxation time and the right and left ventricle myocardial performance indices were higher in the fetuses of the obese mothers than in the fetuses of the healthy mothers. We believe that maternal obesity has an important influence on fetal cardiac diastolic functions.

RESUMEN

Laminin receptor 1 (LAMR) may have a role in the progression of premalignant squamous epithelial lesions to cervical cancer. Therefore, we aimed to investigate the expression of laminin receptor 1 (LAMR) in normal, premalignant, and malignant tissues of the uterine cervix. Paraffin blocks of 129 specimens with the diagnoses of normal cervical tissue (n = 33), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2 (n = 14), CIN 3 (n = 28), and squamous cell carcinoma (n = 24) were immunohistochemically stained with LAMR antibody and its expression percentage, pattern, and intensity in these tissues were assessed. Compared to the other groups, the nonstaining with LAMR was highest in low grade squamous intraepithelial lesion (LSIL) (p < 0.0001). LAMR expression, which was positive in less than 50% of cells with weak staining, increased significantly between normal cervical epithelium and high-grade squamous intraepithelial lesion (HSIL) or invasive carcinoma, as well as between LSIL and HSIL (p < 0.0001). Between LSIL and invasive carcinoma, a significant increment was also observed for weak staining in less than 50% of cells (p < 0.001). LAMR expression, which was positive in more than 50% of cells with strong staining, was significantly higher in normal cervical tissue compared to the other groups (p < 0.0001). Disease progression related gradual increment of LAMR expression from normal cervical epithelium or LSIL towards HSIL or cervical cancer reveals that LAMR may play an important role in the transition from premalignant to malignant state in cervical lesions.

RESUMEN

OBJECTIVES: To evaluate sexual function and psychological state and the factors affecting female sexual dysfunction in predialysis and hemodialysis patients. DESIGN AND METHODS: Forty-seven women with chronic renal failure including 22 predialysis patients, 25 hemodialysis patients, and 30 healthy controls were included in this study. Demographic and clinical variables of the patients were recorded. The sexual functions and psychological states of the patients, assessed by the Arizona Sexual Experiences Scale (ASEX) and Beck Depression Inventory (BDI), respectively, were compared between the groups. RESULTS: Total ASEX scores, ability to reach orgasm, and BDI scores were significantly higher in predialysis and hemodialysis patients than controls, reflecting sexual dysfunction. The patients in the predialysis group were 6 and 3.8 times more likely to develop depressive symptoms compared to the controls and hemodialysis patients, respectively. The predialysis patients who showed depressive symptoms were 24 times more likely to develop sexual dysfunction compared to those without depression. Serum FSH and LH levels were also positively correlated with arousal and erection/lubrication scores in the predialysis patients with depressive symptoms. CONCLUSION: Female predialysis rather than dialysis patients might be more likely to develop depression. Those patients with depressive symptoms may also be at greater risk of developing sexual dysfunction in which increased gonadotropin levels and age may also be contributing factors. Therefore, psychiatric and gynecologic consultations may be beneficial.

RESUMEN

OBJECTIVE: To evaluate serum myeloperoxidase (MPO) and adenosine deaminase activities and to investigate whether there was a correlation between these and sex hormones, and lipids in polycystic ovary syndrome. DESIGN AND METHODS: Forty-five women with polycystic ovary syndrome and 40 healthy controls were included in this study. Leukocyte counts, serum MPO and adenosine deaminase activities, and high-sensitive C-reactive protein (hs-CRP), sex hormone and lipid levels were assessed. RESULTS: Leukocyte counts and serum MPO activities were higher (p < 0.01 and p < 0.05, respectively) and there was a significant correlation between serum adenosine deaminase and hs-CRP level in women with polycystic ovary syndrome (r = 0.853, p < 0.01). Serum MPO and adenosine deaminase levels did not correlate with sex hormones or lipid profiles in these patients. CONCLUSION: Polycystic ovary syndrome may involve an inflammatory process by increasing serum MPO activity independent of sex hormones, body mass index and lipid profiles.

RESUMEN

We aimed to evaluate whole blood adenosine deaminase (ADA), myeloperoxidase (MPO), butyrylcholinesterase (BChE), and acetylcholinesterase (AChE) activities and to investigate whether there was a correlation between these enzymes and severity of preeclampsia and neonatal outcomes. Sixty-one pregnant women with mild (n = 31) or severe (n = 30) preeclampsia and 50 healthy controls were included in this study. Whole blood adenosine deaminase, myeloperoxidase, butyrylcholinesterase, and acetylcholinesterase activities were measured. Adenosine deaminase and myeloperoxidase activities were significantly higher in both mild and severe preeclamptic women than they were in the controls. There was also a significant difference between the severe and the mild preeclamptic groups with respect to these enzyme activities. Although BChE activity was lower in the severe preeclamptic women than it was in the healthy controls (P < .05), AChE activity was similar in all groups (P > .05). We noted an inverse correlation between ADA activity and birth weight (r = -0.337) (P < .05) and between MPO activity and Apgar scores at 1 and 5 minutes (r = -0.438 and r = -0.475, respectively, P < .01). We concluded that elevated ADA and MPO but not AChE activities may correlate with disease severity and neonatal outcomes in preeclamptic women. Further studies are needed to elucidate the exact roles of ADA and MPO in the pathophysiology of preeclampsia.

RESUMEN

OBJECTIVE: To investigate the effect of intranasal estrogen replacement therapy administered to postmenopausal women alone or in combination with progesterone on markers of cardiovascular risk. METHODS: The study was conducted with 44 voluntary postmenopausal women. In group I (n = 15), the patients were treated with only intranasal estradiol (300 µg/day estradiol hemihydrate). In group II (n = 11), the patients received cyclic progesterone (200 mg/day micronized progesterone) for 12 days in each cycle in addition to continuous intranasal estradiol. Group III (n = 18) was the controls. Serum lipid profiles, oxidised low-density lipoprotein (LDL) and other markers of cardiovascular risk were assessed at baseline and at the 3rd month of the treatment. RESULTS: Lipid profile, LDL apolipoprotein B, lipoprotein a, homocysteine, oxidised LDL values and oxidised LDL/LDL cholesterol ratio were not observed to change after 3 months compared to baseline values within each group (p > 0.016). In comparison to changes between the groups after the treatment, only oxidised LDL levels and oxidised LDL/LDL cholesterol ratios of group II were increased compared to control group (p < 0.05). CONCLUSIONS: Intranasal estradiol alone did not appear to have an effect on markers of cardiovascular risk in healthy postmenopausal women. However, the addition of cyclic oral micronized progesterone to intranasal estradiol influenced the markers of cardiovascular risk negatively in comparison to non-users in healthy postmenopausal women.

RESUMEN

OBJECTIVES: To investigate the expression of laminin receptor 1 (LR1), a non-integrin-type laminin receptor, in preeclamptic and normal third-trimester placentas, as well as to investigate whether its expression differs with disease severity. STUDY DESIGN: Third trimester placental samples obtained from deliveries of preeclamptic (n=34) and normotensive healthy pregnant women (n=35) were immunohistochemically studied for the expression of LR1. The placentas from both mild (n=14) and severe (n=20) preeclamptic pregnancies were further assessed for strength of LR1 expression according to disease severity. RESULTS: When compared with normal placentas, the staining with LR1 protein in cytotrophoblasts and syncytiotrophoblasts was lower in preeclamptic placentas (P<0.05 and P<0.01, respectively). The intensity of staining with LR1 in decidual cells, cytotrophoblasts, syncytiotrophoblasts, and extracellular matrix cells of preeclamptic placentas did not vary with disease severity (P>0.05). CONCLUSIONS: Decreased LR1 expression in cytotrophoblasts and syncytiotrophoblasts of preeclamptic placentas, which may be independent of disease severity, might have a role in shallow trophoblastic invasion in preeclampsia.

RESUMEN

PURPOSE: To investigate serum high sensitivity C-reactive protein (hs-CRP) levels and endothelial function in pregnancies complicated by pre-eclampsia and to clarify their relationship with uterine artery Doppler velocimetry. METHODS: A cross-sectional study was carried out in 70 pregnant women (35 patients with pre-eclampsia and 35 age-matched normotensive healthy pregnant women) during the third trimester of pregnancy. The maternal levels of serum hs-CRP were determined in all cases by immunonephelometry. Uterine artery Doppler velocimetry was performed. Flow-mediated dilatation was measured by sonography of the brachial artery for the assessment of endothelial function. RESULTS: Serum hs-CRP levels were higher in the pre-eclamptic group than in the normotensive group. hs-CRP levels were positively correlated with mean arterial pressure. Eleven patients with pre-eclampsia had abnormal uterine artery Doppler velocimetry. hs-CRP levels were significantly higher in pre-eclamptic patients with than without abnormal uterine artery Doppler velocimetry. Endothelial function was inversely correlated with hs-CRP levels and mean arterial pressure. CONCLUSIONS: These findings suggest that maternal serum hs-CRP levels increase with the severity of pre-eclampsia, reflecting endothelial dysfunction and constituting a potential marker of pathological utero-placental perfusion, with a high risk for fetal growth restriction.

RESUMEN

PURPOSE: We report the successful management of a pregnancy with preexisting nephrotic syndrome due to biopsy-proven primary membranoproliferative glomerulonephritis type I. METHODS: A 21-year-old Turkish woman with membranoproliferative glomerulonephritis type I was followed up by the obstetrics and gynecology, and nephrology departments of a university hospital throughout her pregnancy starting from the 25th week of gestation. RESULTS: Due to progression of intrauterine growth retardation and fetal distress, a cesarean section was performed in the 33rd week of gestation. Although creatinine was unchanged, proteinuria increased with relatively stable albumin levels 3 months after delivery and her treatment was adjusted accordingly. CONCLUSIONS: If the mother is not suffering from hypertension or renal insufficiency, specific therapy for membranoproliferative glomerulonephritis type I during pregnancy provided by a nephrologist together with regular obstetric care may allow the patient to have a viable fetus, which might be growth retarded if proteinuria is increased.

RESUMEN

OBJECTIVE: To review our experience with preterm premature rupture of membranes at a tertiary-care hospital in Turkey to determine whether the amount of residual amniotic fluid after rupture has prognostic value for adverse maternal and fetal outcomes. METHODS: We reviewed the medical records of 191 pregnant women with gestational ages between 24 and 34 weeks at the time of rupture of the amniotic membrane and of their babies delivered in our hospital between January 1996 and September 2008. On the basis of amniotic fluid index (AFI) values recorded at the time of admission, patients were categorized into two groups: those with an AFI < 50 mm (n = 119) and those with an AFI > 50 mm (n = 72). RESULTS: The patients with high gravidity (4-8) were more prevalent in the group with an AFI < 50 mm (37 vs. 23.6%), while nulliparous women were more common in the group with an AFI > 50 mm (44.4 vs. 30.2%) (P < 0.05). Seventy-two percent of the cesarean sections performed due to nonreassuring fetal status were in the group with an AFI < 50 mm (P < 0.01). In 71.4% of the cases with a 5 min Apgar score < or = 7, AFI was less than 50 mm (P < 0.01). AFI < 50 mm was present in 65, 70.8, 76.7, and 73.1% of the pregnancies complicated by chorioamnionitis, respiratory distress syndrome, composite neonatal morbidity, and neonatal death, respectively (P < 0.05). CONCLUSIONS: A residual AFI < 50 mm after preterm PROM between 24 and 34 weeks of gestation, which is mostly seen in grand multiparous women in Eastern Turkey, may be a valuable prognostic variable for anticipating adverse maternal and neonatal outcomes.

RESUMEN

PURPOSE: The purpose of this study was to evaluate the short-term efficacy and complication rates of posterior intravaginal slingplasty (IVS) procedures. METHODS: Thirty-four patients who had advanced (grade 4) uterine prolapse were recruited. All patients underwent vaginal hysterectomy and the cuff was suspended with a posterior IVS operation. The mean follow-up duration was 12 months (range 3-20 months). RESULTS: Thirty-three patients (97.1%) had satisfactory level I support defined objectively as stage 0 or I for point C as described in the pelvic organ prolapse quantification system. There were no rectal, vesical, ureteric, or vascular injuries in this series. During the postoperative period no complications, including tape erosion, were seen. CONCLUSIONS: Posterior IVS is a minimally invasive procedure for grade 4 genital prolapse with a high success rate.

RESUMEN

AIM: To review our experience with brucellosis in pregnancy and to characterize the risk factors, clinical presentations, the rates of possible perinatal complications, and the effect of hospitalization on pregnancy outcomes. METHODS: We reviewed the medical records of 21 pregnant women at a tertiary care hospital and 12 at a maternity hospital, who presented with acute, subacute, chronic, or relapsing brucellosis. Their risk factors and clinical presentations were defined. The reproductive outcomes of 29 cases were compared within themselves according to the hospitals they were managed and with the outcomes for all women followed in the maternity hospital for the period from January 2008 through December 2008. RESULTS: Consumption of unpasteurized dairy products had occurred in 92.3% of the cases. Spontaneous abortion, intrauterine fetal death, and preterm delivery rates were 24.14, 3.45, and 6.9%, respectively. Only spontaneous abortion rate substantially exceeded that among the general population of pregnant women in our maternity hospital (P<0.05). Hospitalization did not affect pregnancy outcomes significantly (P>0.05). CONCLUSIONS: Brucellosis in pregnancy is associated with increased incidence of spontaneous abortion without an association with the magnitude of serum agglutination titer, the clinical type of brucellosis and hospitalization. In endemic areas with inhabitants of low socioeconomic class and low educational level, educating women of childbearing age about brucellosis may help to prevent the disease and its complications in pregnancy.

RESUMEN

Aneurysm of the vein of Galen is a rare congenital vascular malformation of the central nervous system. There are controversies in the literature regarding the possible prognostic value of aneurysmal volume estimation with 3-dimensional US for the prediction of fetal outcome. In this report, we present a case of prenatally diagnosed large aneurysm of the vein of Galen complicated by heart failure in a fetus. The volume of the malformation was calculated as 17.8 cm(3) and the fetal outcome was poor.
