Abstract
BACKGROUND Healthcare professionals regularly read the summary of product characteristics (SmPC) as one of the various sources of information on the risks of drug use in women of childbearing age and during pregnancy. The aim of this article is to present an overview of the teratogenic potential of various antiepileptic drugs and to compare these data with the information provided by the SmPCs. METHODS A literature search on the teratogenic risks of 19 antiepileptic agents was conducted and the results were compared with the information on the use in women of childbearing age and during pregnancy provided by the SmPCs of 38 commercial products available in Switzerland and Germany. RESULTS The teratogenic risk is discussed in all available SmPCs. Quantification of the risk for birth defects and the numbers of documented pregnancies are mostly missing. Reproductive safety information in SmPCs showed poor concordance with risk levels reported in the literature. Recommendations concerning the need to monitor plasma levels and possibly perform dose adjustments during pregnancy to prevent treatment failure were missing in five Swiss and two German SmPCs. DISCUSSION The information regarding use in women of childbearing age and during pregnancy provided by the SmPCs is heterogeneous and poorly reflects the current state of knowledge. Regular updates of SmPCs are warranted in order for these documents to be of reliable use for health care professionals.

Abstract
The purpose of this review is to discuss gender-related aspects in the, pharmacokinetics, effects, selection and use of antiepileptic drugs (AED). In general, there are few known gender related differences in pharmacokinetics or efficacy of AEDs. Conversely, gender has a significant influence on the susceptibility to certain adverse effects, not the least those involving alterations in sex hormone metabolism. Particularly relevant are the teratogenic effects of AEDs, with important differences among AEDs in their potential to cause adverse effects on the fetus when used during pregnancy. Pregnancy can also markedly affect the pharmacokinetics of several AEDs, and dose adjustments are often needed during pregnancy to maintain seizure control. Some treatments that are used only by women, such as contraceptive steroids and hormone replacement therapy, can also interact with AEDs to an extent that may affect the utilization of both the AEDs and the other drug.

Abstract
PURPOSE We explored the contraceptive experiences of female teens with epilepsy, including their knowledge and perceptions of interactions between antiepileptic drugs and hormonal contraception and contraceptive decision-making processes. METHOD From November 2012 to May 2013, we conducted one online survey (n=114) and 12 online focus group discussions (n=26) with female teens with epilepsy about their contraceptive experiences and unmet needs. Survey data were analyzed using descriptive statistics and focus group transcripts were analyzed thematically using modified grounded theory methods. RESULTS Both survey and focus group participants reported believing that interactions between epilepsy medications and hormonal contraceptives could lead to reductions in contraceptive efficacy and seizure control. However, their knowledge about these types of medication interactions was often incomplete. Many study participants viewed contraceptive decision making as a difficult process, and some participants reported avoiding hormonal contraceptives because of potential interactions with antiepileptic drugs. Study participants reported relying on health care providers and parents for contraceptive decision-making support. Focus group participants also reported they wanted health care providers to provide more in-depth and comprehensive counseling about contraception, and that they desired peer support with contraceptive decisions. CONCLUSION The ability to make informed contraceptive decisions is important for teens with epilepsy as interactions between anti-epileptic drugs and hormonal contraceptives can impact seizure occurrence and lead to an increased risk of unplanned pregnancy. Guidance for providers offering contraceptive care to this population is needed, as well as a contraceptive support tool that empowers teens with epilepsy to advocate for desired health care.

Abstract
Introduction Many antiepileptic drugs decrease the efficacy of combined hormonal contraceptives due to their inducing effect on cytochrome P450 liver metabolism. Less is known about the pharmacokinetics and outcomes of concomitant use of the etonogestrel implant and hepatic enzyme-inducing medications. Case presentation A 22-year-old Hispanic woman with a long-standing seizure disorder treated with carbamazepine for 9 years became pregnant after 25 months of etonogestrel implant use. Conclusions Hepatic enzyme-inducing drugs may reduce the efficacy of contraceptive implants. Contraceptive counseling for patients with medical co-morbidities requiring hepatic enzyme-inducing medications should include this information.

Abstract
OBJECTIVE The objective of this study was to investigate psychiatric disease and social aspects in young women with epilepsy before and during pregnancy. METHOD The study included self-reported data from 106,935 pregnancies. RESULTS Seven hundred eleven women reported having epilepsy, and 45.9% of them were using antiepileptic drugs (AEDs). Compared to the reference group, self-reported eating disorders and depression were increased in the untreated epilepsy group before pregnancy. Both AED-treated and untreated women with epilepsy reported higher depression scores as assessed by the Hopkins Symptom Checklist, and the Lifetime Major Depression scale was increased in AED-treated women. Antiepileptic drug treatment was linked to low income (27.4% vs. 18.4%, p<0.001) and no income (5.5% vs. 2.6%, p=0.001). Low educational level was associated with epilepsy in AED-treated and untreated women (50.5%, p<0.001 and 46.9%, p<0.001 vs. 32.2%), as was unemployment due to disability (7.9%, p<0.001 and 6.5%, p<0.001 vs. 1.5%) and single parenting (4.4%, p=0.016 and 4.5%, p=0.007 vs. 2.4%). No difference was found for smoking, alcohol use, or narcotic use. CONCLUSION Symptoms of depression were associated with epilepsy both during and before pregnancy. Epilepsy was linked to eating disorders before pregnancy. Unemployment, single parenting, and low educational level were linked to epilepsy in young pregnant females. Efforts aiming at treatment and screening for psychiatric comorbidity in pregnant women with epilepsy are important in the follow-up of these patients.

Abstract
PURPOSE Demonstrate changes in methods of menstrual suppression in adolescents with developmental disabilities in a recent 5-year cohort compared with an historical cohort at the same hospital. METHODS Retrospective cohort study of patients with physical and cognitive challenges presenting for menstrual concerns at an Adolescent Gynecology Clinic between 2006 and 2011 compared with a previous published cohort (1998 to 2003). RESULTS Three hundred patients with developmental disabilities aged 7.3 to 18.5 years (mean 12.1 ± 1.6) were analyzed. Caregiver concerns included menstrual suppression, hygiene, caregiver burden, and menstrual symptoms. Ninety-five percent of patients had cognitive disabilities, 4.4% had only physical impairments. Thirty-two (31.7) percent of patients presented premenarchally. The most commonly selected initial method of suppression was extended or continuous oral contraceptive pill (OCP) (42.3%) followed by patch (20%), expectant management (14.9%), depot medroxyprogesterone acetate (DMPA) (11.6%), and levonorgestrel intrauterine system (LNG-IUS) (2.8%). Published data from 1998 to 2003 indicated a preference for DMPA in 59% and OCP in 17% of patients. The average number of methods to reach caregiver satisfaction was 1.5. Sixty-five percent of initial methods were continued. The most common reasons for discontinuation were breakthrough bleeding, decreased bone mineral density, or difficulties with patch adherence. Second-choice selections included OCP (42.5%), LNG-IUS inserted under general anesthesia (19.2%), DMPA (17.8%), and patch (13.7%). CONCLUSIONS Since identification of decreased bone mineral density with DMPA and emergence of new contraceptive options, use of extended OCP or patch has surpassed DMPA for menstrual suppression in our patient population. LNG-IUS is an accepted, successful second-line option in adolescents with developmental disabilities.

Abstract
Psychiatric disorders are common in adolescent girls and may require chronic therapies with psychotropic medications. Antipsychotic medications and mood stabilizers have been increasingly prescribed to and widely used by adolescents for a variety of both "on" an "off" label indications. Studies on the safety and monitoring of these medications in adolescent girls have shown important potential for gynecologic and reproductive adverse effects. The objective of this article is to review the mechanisms for and management of menstrual disorders mediated by hyperprolactinemia associated with antipsychotic medications, hypothyroidism associated with lithium and quetiapine, and the independent association of polycystic ovary syndrome (PCOS) in girls using valproic acid. Beyond their susceptibility to these disruptions in the menstrual cycle, adolescent girls with psychiatric illness also have increased sexual risk behaviors. These behaviors makes it all the more important to review teratogenicity and clinically relevant contraceptive drug interactions in adolescent girls using these psychotropic medications.

Abstract
OBJECTIVE To estimate continuation rates, complications, and psychiatric hospitalizations among women with bipolar disorder using levonorgestrel-releasing or copper-containing intrauterine devices (IUDs) as compared with those using depot medroxyprogesterone acetate or sterilization for birth control. METHODS Data for this cohort study were obtained from a nationwide health insurance claims database on an employed, commercially insured population. Women aged 18-44 years with a prior diagnosis of bipolar disorder (n=849) who were using the levonorgestrel intrauterine system, a copper-containing IUD, depot medroxyprogesterone acetate, or sterilization were evaluated. Outcomes included continuation rates over a 12-month interval, infectious and noninfectious complications, and hospitalizations for bipolar disorder or depression. RESULTS Women using an IUD were more likely than those using depot medroxyprogesterone acetate to continue the method for at least 12 months (copper-containing IUD, 86%; levonorgestrel intrauterine system, 87%). In comparison, only 31% of those who initiated depot medroxyprogesterone acetate received three more injections during the next year (P<.001). No significant differences were noted in infectious or noninfectious complications by contraceptive type. Finally, no differences were observed in the number of hospitalizations for bipolar disorder or depression among the four contraceptive groups. CONCLUSION More women with bipolar disorder continued using IUDs at one year than women using depot medroxyprogesterone acetate. The rates of complications and psychiatric hospitalizations were not different among women using an IUD, depot medroxyprogesterone acetate, or sterilization. LEVEL OF EVIDENCE II.

Abstract
Sexual behavior is common in adolescents and young adults with or without chronic illness or disability, resulting in high levels of unplanned pregnancy and STDs. Individuals with chronic illness or disability should not receive suboptimal preventive health care. These individuals have a need for counseling regarding issues of sexuality and contraception. Sexually active adolescent and young adult women can be offered safe and effective contraception if they wish to avoid pregnancy. Women with chronic illnesses and disabilities who are sexually active should also be offered contraception based on their specific medical issues. Condoms are also recommended to reduce STD risks. Table 36 summarizes basic principles of contraception application for specific illnesses, which have been identified since the release of the combined OC in 1960. Clinicians should also consider the noncontraceptive benefits of this remarkable and life-changing technology that allows all reproductive age women to improve their lives, including those with chronic illnesses and disabilities.
