Association between fertility drugs and gynecologic cancers, breast cancer, and childhood cancers

Ovulation‐inducing drugs have been widely used for various types of infertility since the beginning of 1960s and their use increases day by day parallel to the success achieved in fertility treatment. However, the researches performed in the last two decades have begun to discuss about the safety of these drugs and the risks associated with their use. Especially, the potential neoplastic effects of these drugs are increasingly questioned. The studies have discussed whether there is an association between the exposure to ovulation‐inducing drugs and the incidence of various cancers. Moreover, several studies have been performed to reveal whether there is an increased risk of childhood cancers in children conceived after fertility treatment. The point we reached through the available data is that the risk of breast, uterine and invasive ovarian cancers is not increased, but the risk of borderline ovarian tumors might increase after such a therapy. The risk of cancer has been found similar for children conceived after fertility treatment and those conceived naturally. It should also be kept in mind that cancers are overdiagnosed in infertile women population because of the close medical surveillance, which may also contribute to the early detection of cancers. Although it is still early to state the last words on this topic, the possible association should be addressed when obtaining an informed consent before starting treatment.

Evaluation of periodontal pathogens in amniotic fluid and the role of periodontal disease in pre-term birth and low birth weight

Abstract Background. Pre-term birth and/or low birth weight (PTLBW) is a serious problem in developing countries. The absence of known risk factors in ∼ 50% of PTLBW cases has resulted in a continued search for other causes. The aim of this study was to examine the effect of periodontitis on pregnancy outcomes. Methods. Samples were taken from 50 pregnant women who underwent amniocentesis. Polymerase chain reaction was performed on amniotic fluid samples obtained during amniocentesis and on subgingival plaque samples to determine the presence of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus and Eikenella corrodens. Plaque index, gingival index, bleeding on probing, probing depth and clinical attachment level were evaluated. Medical records were obtained after birth. Results. Social and demographic variables were similar among the Gingivitis (G), Localized Periodontitis (LP) and Generalized Periodontitis (GP) groups. Four subjects gave birth to PTLBW neonates. Campylobacter rectus, T. forsythia, P. gingivalis and F. nucleatum were detected in the amniotic fluid and subgingival plaque samples of three patients who gave birth to PTLBW neonates. The amniotic fluid sample from the fourth patient was not positive for any of the tested pathogens. Conclusion. These findings suggest that the transmission of some periodontal pathogens from the oral cavity of the mother may cause adverse pregnancy outcomes. The results contribute to an understanding of the association between periodontal disease and PTLBW, but further studies are required to better clarify the possible relationship.

Surgical outcome of transobturator tape procedure in obese and non-obese women

The objective of this study was to assess the impact of body mass index (BMI) on transobturator tape (TOT) success rates, patient acceptability and complications 1 year following surgery. The medical records of stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) patients who underwent the TOT operation were retrospectively reviewed. The patients were divided into non-obese (BMI < 25) and obese (BMI ≥ 30) groups. Baseline and 1 year post-surgical outcomes were assessed by including multichannel urodynamics, Urogenital Distress Inventory (UDI-6) scores, Incontinence Impact Questionnaire (IIQ-7) scores and cure, failure and success rates. There were no significant differences between groups in terms of urodynamic parameters, objective cure rate and subjective success, quality of life scores, or postoperative complications. Both obese and non-obese patients had cure and/or improvement of their symptoms and had better quality-of-life in the postoperative period. As a conclusion, BMI does not affect the clinical effectiveness of TOT operation in the treatment of female SUI or MUI.

Outcome of sonographically suspected fetal ovarian cysts

Abstract Objective: Fetal ovarian cysts (FOCs) are the most common intra-abdominal cystic structures formed during antenatal period. The aim of this study was to evaluate prenatal characteristics and postnatal outcome of sonographically suspected FOCs. Methods: We reviewed prenatal sonographic data and postnatal medical records of 29 fetuses that were suspected to have ovarian cysts in our hospital, between January 2001 and September 2012. Perinatal outcomes were obtained for all cases. Results: In a total of 29 cases, we confirmed initial antenatal diagnosis of ovarian cyst in 20 cases (68.9%) at postnatal period. Diagnosis of remaining nine cases revealed urogenital sinus anomaly in four cases, multicystic dysplastic kidney in two cases, mesenteric cyst in one case, intestinal duplication cyst in one case and lymphangioma in one case postnatally. In seven of the 20 ovarian cysts (35%), resolution of the cyst occurred prenatally. Intrauterine death of a fetus occurred at second trimester. In the postnatal period, most often cases (11/20) were spontaneously resolved and surgery was performed on two babies due to ovarian torsion (2/20). Conclusion: Differential diagnosis of FOCs should always include genitourinary tract disorders, gastrointestinal tract disorders and other intra-abdominal cystic structures.

Perinatal Outcomes of Fetal Abdominal Cysts and Comparison of Prenatal and Postnatal Diagnoses

Introduction: The differential diagnosis of an abdominal cyst can be challenging, and an accurate diagnosis is crucial for optimal antenatal management. The aim of this study was to compare the ante- and postnatal diagnoses of cases with abdominal cyst and to determine the diagnostic accuracy of ultrasonography. Material and Methods: A database review was performed regarding the diagnosis of fetal abdominal cyst covering the period 2002–2009. Structural characteristics and localizations of the cysts in the abdomen were recorded. Ante- and postnatal diagnoses were classified into systems according to the origin of the cyst and were compared. Perinatal outcomes were obtained for all cases. Results: 71 cases with an abdominal cyst were identified. The mean gestational age at the time of diagnosis was 25 ± 5.1 weeks. In 9 cases, there were extra-fetal structural abnormalities, and in 5 cases a chromosomal abnormality was determined. Seven pregnancies were terminated. Overall spontaneous mortality was 11/64 (17%). In 12/64 cases (18%), the cyst resolved at birth. After birth, nearly half of the cases required surgical correction and of these, 20% died. Sensitivity, specificity and positive predictive value of ultrasonography in identifying the system of origin were 88.1, 95.7 and 92.0%, respectively, with a 4.1% false-positive rate. Conclusion: Incorporation of different disciplines in the counseling, management and postpartum follow-up is crucial. Postnatal physical examination of fetuses with an abdominal cyst will help to prevent unnecessary surgery.

Alcohol Injection for the Intrauterine Treatment of Chorioangioma in a Pregnancy with Transfusion Resistant Fetal Anemia: A Case Report

Chorioangiomas are usually small, clinically inevident, benign vascular lesions of the placenta, but larger ones may cause serious perinatal and neonatal complications. There is need for in utero intervention in these fetuses. Several interventions are described to relieve pathophysiologic insult on fetus. Alcohol injection is one of the therapeutic interventions. In this case, we present a patient with chorioangioma and early onset of hydrops fetalis and polyhydramnios at 24th week of gestation. Successful intratumoral injection of absolute ethyl alcohol relieved hydrops fetalis and polyhydramnios. Unfortunately, pregnancy ended at 28th week and a 1,330 g fetus was delivered.

Etiology and Outcome of Hydrops Fetalis: Report of 62 Cases

AIM We aimed to define the etiologic and prognostic factors in live-born infants with hydrops fetalis (HF) in our tertiary neonatal intensive care unit over a 10-year period. METHODS Medical records of newborn infants with HF during 2002-2011 were reviewed retrospectively. Demographic data, prenatal interventions, clinical and laboratory findings, outcomes, and the results of postmortem examinations were analyzed. RESULTS During the study period, 62 newborn infants with HF were identified from 16,200 live-born deliveries and the incidence of HF was 3.8/1000 live births in our hospital. Twenty-eight infants (45.2%) had immune HF, whereas 34 (54.8%) had nonimmune HF. An etiologic factor could be identified in 24 (70.5%) infants with nonimmune HF. Lymphatic dysplasias comprised the majority (23.5%) of the infants with nonimmune HF. Mortality rate was 50%. The presence of two or more serous cavity effusions and gestational age were independently associated with the risk of mortality. CONCLUSION Despite the improvements in neonatal care, mortality rate in infants with HF is still high. Gestational age and the extent of serous cavity determine the risk of mortality. Timely and advanced prenatal or postnatal new therapeutic strategies may alter this fatal outcome in appropriate patients.

Maternal blood and amniotic fluid levels of moxifloxacin, levofloxacin and cefixime

Aim:  Moxifloxacin and levofloxacin are wide spectrum quinolones and cefixime is a third‐generation cephalosporin with a wider spectrum of activity against gram‐positive and gram‐negative bacteria and anaerobics. Although they are widely used, little is known about the amniotic fluid levels of these antibiotics. The aim of the present investigation was to study and compare the maternal blood and amniotic fluid levels of these antibiotics in second trimester pregnancy.

Pregnancy-associated breast cancer: clinicopathological characteristics of 20 cases with a focus on identifiable causes of diagnostic delay.

Background: The primary objective of this study was to evaluate the clinicopathological characteristics of patients with pregnancy-associated breast cancer (PABC), with a special focus on diagnostic delays and the identifiable causes of diagnostic delays. Patients and methods: Clinicopathological data of patients treated for PABC between 2003 and 2012 at Hacettepe University Hospital was retrospectively reviewed. Results: 20 patients with PABC were included. The pathological examination revealed predominance of invasive ductal carcinoma (80%), grade III tumors (65%) and advanced-stage (III-IV) disease (75%). In 8 patients (40%), there was a diagnostic delay between occurrence of the presenting symptoms and the initiation of breast mass workup. For these 8 patients, the main identifiable causes of diagnostic delay were the attribution of disease-related symptoms to pregnancy or lactation in 5 (63%) and negligence of symptoms in 2 (25%). Conclusions: PABC mostly presents with advanced-stage disease, and there can be a substantial diagnostic delay before these patients receive treatment. Preconceptional, gestational and postpartum examination of women of reproductive age should include a thorough breast examination and should provide adequate information regarding the physiological changes in breast tissue and the possible pathological symptoms.
