Molar Pregnancy in Adolescents

OBJECTIVE: To describe the clinical presentation of hydatidiform molar pregnancy in women under the age of 20 years. In addition, we sought to understand if this adolescent population manifests differences in clinical factors compared to an adult population that may affect outcome.STUDY DESIGN: We used a database from the New England Trophoblastic Disease Center to analyze clinical data from all women followed for molar pregnancy between 1970 and 2009 with complete follow-up information. This population was stratified by age and clinical parameters including presenting signs, molar histology and development of gestational trophoblastic neoplasia (GTN). Univariable and multivariable logistic regression was employed to discern clinical factors that associated with adolescent age. The Partners Human Research Committee approved this study.RESULTS: We identified 1,494 women diagnosed with hydatidiform mole (HM), of which 220 (14.7%) were adolescents defined as age <20 years. The most common presenting clinical signs were vaginal bleeding and an enlarged uterus compared to dates. Median gestational age at diagnosis was 13.4 weeks, not different from that in the adult population. Similarly, no difference in presenting human chorionic gonadotropin was observed between the adult and adolescent populations. Adolescents presented with a significant overrepresentation of complete mole (86% vs. 75%, p < 0.001) compared to adults. Complete mole was associated with a heightened risk of developing GTN (OR 2.6, 95% CI 1.9-3.5), and despite the association of complete mole with young maternal age, univariable analysis showed no difference in the rate of GTN observed between adolescents and adults (24% vs. 30%, p = 0.08). Multivariable analysis controlling for molar histology demonstrated that adolescent age was associated with a decreased risk of GTN (hazard ratio 0.67, 95% CI 0.48 0.93).CONCLUSION: Adolescents account for a substantial proportion of the population with HM. They commonly present with vaginal bleeding. Though this population develops a complete mole with a higher frequency than adults, adolescents appear to have a significantly decreased risk of developing GTN. (J Reprod Med 2012; 57:225-230)

Thyroid cell proliferation in Graves' disease - Use of MIB-1 monoclonal antibody

OBJECTIVE: To measure thyroid cell proliferation in patients with Graves' disease (GD) before and during treatment with antithyroid drugs.STUDY DESIGN: Patients were assessed by fine needle aspiration biopsy before (n=20) and after 4 (n=19) and 12 months of treatment (n=15) with propylthiouracil or methimazole. Cell proliferation index (CPI) was estimated by immunocytochemistry using MIB-1. CPI was studied in relation to the cytologic parameters of the smears; clinical parameters, such as Wayne's Clinical Index (WCI) and time without treatment; laboratory parameters, such as (131)Iuptake and dosage of serum free thyroxin and thyroid-stimulating hormone; and thyroid ultrasound.RESULTS: CPI varied from 0.00% to 25.00% before treatment, 0.00% to 23.00% at 4 months and 0.00% to 14.84% at 12 months. CPI median values were 6.50%, 4.30% and 3.30%, respectively (before and after 4 months and 12 months of treatment). CPI had a positive correlation with WCI and FT4 at 12 months of treatment.CONCLUSION: Thyroid CPI in GD varies from case to case. However, due to its decreasing pattern during follow-up and its positive correlation with thyrotoxicosis severity, CPI may indicate the functional status of the gland and contribute to a better understanding of GD.

Primary Pulmonary Choriocarcinoma After Human Chorionic Gonadotropin Normalization Following Hydatidiform Mole A Report of Two Cases

BACKGROUND: Primary pulmonary choriocarcinoma (PPC) is rare and frequently leads to death.CASES: Two young patients presented with previous molar pregnancy and spontaneous serum human chorionic gonadotropin (hCG) normalization. Patient 1 was referred to our center after partial response to chemotherapy. Pulmonary lobectomy was performed, and hCG rapidly declined. During further chemotherapy, liver metastasis was detected by positron emission tomography. Right hepatectomy was performed, and hCG declined for 28 days, but increased again despite chemotherapy. This patient died from hepatic failure 3 years after diagnosis. Patient 2 presented with persistently high hCG, though the affected organ was not identified. Chemotherapy was unsuccessful. Patient reevaluation showed an isolated pulmonary mass. Pulmonary lobectomy was performed; 2 weeks later, hCG was normal and consolidation with 2 cycles of chemotherapy was administered. The patient has been in remission for 24 months. PPC was confirmed by histo pathology and immunohistochemistry in both cases. Gestational origin of the tumor was confirmed by molecular genetic analysis (polymorphic microsatellite markers).CONCLUSION: The possibility of choriocarcinoma cannot be overlooked in young women with an isolated pulmonary mass. Early diagnosis, prompt chemotherapy, and surgical resection in a specialized center improves the prognosis. (J Reprod Med 2010;55:311-316)

Geographical Distribution and Demographic Characteristics of Gestational Trophoblastic Disease

OBJECTIVE: To outline the geographical distribution pattern of gestational trophoblastic disease (GTD) in a referral center in Bahia, Brazil, and determine the demographics of the disease.STUDY DESIGN: We conducted a study of data retrieved from medical records of 140 GTD patients referred to our Trophoblastic Diseases Center in 2002-2007, assessing geographical distribution across health care districts, demographics, referral sources, and previous pregnancy status.RESULTS: The most common GTD types were hydatidiform mole (106, 75.7%), invasive mole (32, 22.9%), choriocarcinoma (1, 0.7%), and placental site trophoblastic tumor (1, 0.7%). GTD incidence was 8.5 in 1,000 deliveries. Most patients originated from the coastal region (East district), which includes the state capital (77.9%). The 20-34 age group predominated (65%). Education level (67.9% attended elementary school only) and employment rate (42.9%) were low. Secondary hospitals were the principal source of referral (84.3%), followed by self-referrals (15.7%). Regarding previous pregnancy status, 42.1% (n = 59) had had term pregnancy, 39.3% (n = 55) no pregnancy, 15% (n = 21) miscarriage, and 0.7% (n = 1) ectopic pregnancy; 4 patients (2.9%) had previous hydatidiform mole.CONCLUSION: GTD predominated in the peak fertility age group and among patients of unfavorable sociodemographic status.

Assessment of Quality of Life and Psychologic Aspects in Patients with Gestational Trophoblastic Disease

OBJECTIVE: To assess quality of life (QoL) and psychological aspects in patients with gestational trophoblastic disease (GTD).METHODS: This cross-sectional self-report study was conducted among 54 women. Validated questionnaires assessed QoL (WHO-QOL-bref), symptoms of depression (Beck Depression Inventory [BDI]) and anxiety (State-Trait Anxiety Inventory [STAI]).RESULTS: Most patients rated overall QoL as good (44.44%) anti were satisfied with their health status (42.59%). Mean QoL domain score was lowest for psychologic health (53.86 +/- 21.46) and highest for social relationships (65.74 +/- 22.41). BDI mean was 15.81 +/- 11.15, indicating dysphoria. STAI means were 46 +/- 6.46 for trait-anxiety and 43.72 +/- 4.23 for state-anxiety, both evidencing medium-high anxiety. Among employed patients, environment domain mean was the highest (p = 0.024). Presence of children resulted in lowest means for physical health (p = 0.041) and environment (p = 0.045). Patients desiring children showed significantly higher means for physical health (p = 0.004), psychological health (p = 0.021) and environment (p = 0.003). Chemotherapy had no significant influence on QoL (p > 0.05).CONCLUSION: This study evidenced psychological impact on GTD patients, suggesting specialized care centers should provide psychological interventions during treatment and follow-up of GTD patients, highlighting the importance of a multidisciplinary approach.

Hydatidiform Mole in Ectopic Pregnancy Clinical, Imaging, Pathological and Immunohistochemical Characteristics

OBJECTIVE: To determine the clinical, pathological, immunohistochemical and imaging characteristics of hydatidiform mole in ectopic pregnancy (HMEP) in all the cases admitted to the Department of Obstetrics and Gynecology, University Hospital of Caracas (HUC), Central University of Venezuela.STUDY DESIGN: Retrospective and comparative study, based on clinical records review of 2 groups: 10 cases with a diagnosis of HMEP and 20 cases with intrauterine hydatidiform mole (IUHM) admitted to the Obstetrics and Gynecology Department of HUC from 1996 to 2010. Clinical, pathological, immunohistochemical and imaging features were analyzed.RESULTS: The prevalence of HMEP in this study was 0.14:1,000 pregnancies; in this group the mean age was 28.8 years, and the mean gestational age at admission was 8.6 weeks. Both groups (HMEP and IUHM) were comparable in these last variables. Abdominal pain and genital bleeding were the most common clinical symptoms in the HMEP group, while it was vaginal bleeding in the IUHM group. Ultrasound findings were similar to those traditionally described in nonmolar ectopic pregnancy. Histology and immunohistochemistry showed that all cases of HMEP were partial mole.CONCLUSION: Although in this study the prevalence of HMEP was high, the size of the sample limits definitive conclusions. This study concludes that all cases of HMEP are partial mole. (J Reprod Med 2012;57:329-332)

Influence of Hydatidiform Mole Follow-Up Setting on Postmolar Gestational Trophoblastic Neoplasia Outcomes A Cohort Study

OBJECTIVE: To assess the influence of hydatidiform mole (HM) management setting (reference center versus other institutions) on gestational trophoblastic neoplasia (GTN) outcomes. METHODS: This cohort study included 270 HM patients attending Botucatu Trophoblastic Diseases Center (BTDC, São Paulo State University, Brazil) between January 1.990 and December 2009 (204 undergoing evacuation and entire postmolar follow-up at BTDC and 66 from other institutions [OIs]). GTN characteristics and outcomes were analyzed and compared according to HM management setting. The confounding variables assessed included age, gravidity, parity, number of abortions and HM type (complete or partial). Postmolar GTN outcomes were compared using Mann-Whitney's test, chi(2) test or Fisher's exact test.RESULTS: Postmolar GTN occurred in 34 (34/204= 16.7%) BTDC patients and in 27 (27/66=40.9%) of those initially treated in other institutions. BTDC patients showed lower metastasis rate (5.8% vs. 48%, p = 0.003) and lower median FIGO (2002) score (2.00 0.00, 3.001 vs. 4.00 [2.00, 7.00], p = 0.003]. Multiagent chemotherapy to treat postmolar GTN was required in 2 BTDC cases (5.9%) and in 8 OI cases (29.6%) (p = 0.017). Median time interval between molar evacuation and chemotherapy onset was shorter among BTDC patients (7.0 [6.0, 10.0] vs. 10.0[7.0, 16.0], p = 0.040). CONCLUSION: BTDC patients showed GTN characteristics indicative of better prognosis. This underscores the importance of GTD specialist centers. (J Reprod Med 2012;57:305-309)

Gestational Trophoblastic Neoplasia Following Molar Ectopic Pregnancy A Case Report

BACKGROUND: Ectopic molar pregnancy is a gestational trophoblastic disease (GTD) of rare occurrence and therefore not always remembered as a diagnostic possibility.CASE: We describe a case of molar ectopic pregnancy in a primiparous woman who developed gestational trophoblastic neoplasia and required chemotherapy to achieve remission.CONCLUSION This case stresses the important role of histopathologic examination in establishing a diagnosis of ectopic molar pregnancy. Moreover, close follow-up of human chorionic gonadotropin levels is required when a GTD is suspected. (J Reprod Med 2008;53:579-582)

Caring for organ donors: the intensive care unit physicians' view

This study examined the meanings that the intensive care unit (ICU) physicians attribute to their practice when caring for brain-dead organ donors. It is a phenomenological study, a qualitative method that searches for describing and understanding the experiences lived. Data were collected through recorded individual interviews made with 10 ICU physicians who work in a university hospital in the interior of São Paulo, Brazil. Three categories emerged from data: (1) providing care for brain-dead organ donors; (2) relating to donors and their families; and (3) the ethical concerns and self-awareness of the physicians. There is consensus as to-many aspects: demand of technical qualification and excellence in practice; need of investing in technology of organ transplant; and donors seen as human beings and holders of human rights. Participants understand that family participation is decisive in the donation process, although interactions between the family members and the physicians are difficult because of the sensitive nature of the situation. The physicians often felt ill-prepared to openly discuss the topic of brain death and organ donation. Educational programs for physicians and family members may assist with this difficult process.
