BACKGROUND: Autoimmune progesterone dermatitis is an uncommon disease presenting with cyclical skin eruptions corresponding with the menstrual cycle luteal phase. Because symptoms are precipitated by rising progesterone levels, treatment relies on hormone suppression. CASE: A 22-year-old nulligravid woman presented with symptoms mistaken for Stevens-Johnson syndrome. A cyclic recurrence of symptoms occurred, and the diagnosis of autoimmune progesterone dermatitis was made by an intradermal progesterone challenge...

A 30-year-old nulligravid woman is referred to you for heavy menstrual cycles. Although her menstrual cycles were previously light, she was recently diagnosed with an unprovoked lower extremity venous thromboembolism and is taking anticoagulation therapy after a negative thrombophilia workup. She wants help with her vaginal bleeding and desires contraception.

Catamenial epilepsy, defined as the exacerbation of the frequency of seizures in a given phase of the menstrual cycle, affects 35% of women. In women with catamenial epilepsy with perimenstrual seizures, progesterone therapy may be effective. In case of enzyme inducer AEDs, hormonal contraception is deprecated (estroprogestative or progestative pill, progestative implant, patches or hormonal rings). Because of its high malformative teratogenic potential, its possible depressive cognitive effects and the autistic risk, sodium valproate is not indicated during pregnancy...

Estradiol production varies cyclically, changes in levels are hypothesized to affect the voice. The main objective of this study was to investigate vocal acoustic and auditory-perceptual characteristics during fluctuations in the levels of the hormone estradiol during the menstrual cycle. A total of 44 volunteers aged between 18 and 45 were selected. Of these, 27 women with regular menstrual cycles comprised the test group (TG) and 17 combined oral contraceptive users comprised the control group (CG). The study was performed in two phases...

STUDY OBJECTIVE: The American Academy of Pediatrics and American College of Obstetricians and Gynecologists have identified the menstrual cycle as essential in assessing overall health of adolescent girls. Menses should be considered a "vital sign" and documentation of last menstrual period (LMP) is recommended at every patient encounter. The aim of this study is to estimate and compare LMP documentation among adolescent and pediatric healthcare providers. STUDY DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study identified a random sample of 50 female patients seen in the general pediatrics (PEDS), adolescent medicine (AM), and pediatric and adolescent gynecology (PAG) ambulatory clinics at Phoenix Children's Hospital between January 1, 2016 and March 31, 2016...

The relationship between early recovery of menstrual activity and blood anti-Müllerian hormone (AMH) concentrations were investigated within the first year post-chemotherapy in 32 young patients with breast cancer. All were treated by surgery and the same chemotherapy protocol (three cycles of FEC100 plus three cycles of taxanes). Menstrual activity, blood AMH (using picoAMH ELISA) and FSH concentrations were measured longitudinally before, during and up to 12 months after the end of chemotherapy (six samples per patient)...

In humans, hormonal regulation is crucial for the preparation of uterine environment leading to either successful implantation or menstrual cycle. Estrogen is a pivotal female steroid hormone that regulates the uterine dynamics along with progesterone in the estrous and menstrual cycles in humans. Estrogen signals act via nuclear estrogen receptor or membrane-bound receptor. The membrane-bound estrogen receptor plays a crucial role in the rapid response of estrogen in the uterine epithelium. Recently, RASD1 has received attention as a novel signal transducer of estrogen in various systems including female reproductive organs...

BACKGROUND: While several studies examined the reactivity towards negative emotional stimuli across women's menstrual cycle, only few investigated responses to positive emotional cues in association with sexual hormones on a neural level. Therefore, the aim of the current EEG-experiment was to study the differential reactivity towards positive (erotic) words during the menstrual cycle (i.e. with fluctuations in the steroids estradiol and progesterone) in the late positive potential (LPP)...

BACKGROUND: Previous studies have reported that hyperthyroid and hypothyroid women experience menstrual irregularities more often compared with euthyroid women, but reasons for this are not well-understood and studies on thyroid hormones among euthyroid women are lacking. In a prospective cohort study of euthyroid women, this study characterised the relationship between thyroid hormone concentrations and prospectively collected menstrual function outcomes. METHODS: Between 2004-2014, 86 euthyroid premenopausal women not lactating or taking hormonal medications participated in a study measuring menstrual function...

Abnormal parturition, e.g. pre- or post-term birth, is associated with maternal and neonatal morbidity and increased economic burden. This could potentially be prevented by accurate detection of abnormal softening of the uterine cervix. Shear Wave Elasticity Imaging (SWEI) techniques that quantify tissue softness, such as shear wave speed (SWS) measurement, are promising for evaluation of the cervix. Still, interpretation of results can be complicated by biological variability (i.e., spatial variations of cervix stiffness, parity), as well as by experimental factors (i...

OBJECTIVE: The goal of the study was to examine differences between adolescents and young women with functional hypothalamic amenorrhea (FHA) and control groups in personality traits, eating attitudes and behaviours, and perception of parental behaviour. BACKGROUND: The FHA is stress-induced anovulation, both related to metabolic challenges, such as excessive exercise and malnutrition, and psychogenic challenges, such as perfectionism and poor coping strategies...

Evidence suggests that females experience adaptive shifts in facial preferences across the menstrual cycle. However, recent discussions and meta-analyses suggest that these findings are equivocal. A previously unexplored question is the extent to which shifts in female preferences are modulated by hormone-dependent changes occurring in low-level vision, such as visual sensitivity. This mechanistic approach has been a novel method for investigating the extent to which complex perceptual phenomena are driven by low-level versus higher-level perceptual processes...

In this chapter we have examined the possibilities of screening endometriosis, both in the general population as well as in the target population. We then proposed decision trees, for primary and secondary care. Currently, there is not enough data in the literature to develop or organize a screening test for endometriosis. Screening for endometriosis is not recommended in the general population (level A). There is also no evidence to support systematic screening in a population with genetic risk factors (endometriosis in a relative), or with other clinical risk factors (increased menstrual volume, short cycles, early menarche) (level A)...

BACKGROUND: The progress of medicine, science, technology, education, and culture improves, year by year, quality of life and life expectancy of the populace. The modern human has a chance to further improve the quality and duration of his/her life and the lives of his/her loved ones by bringing their lifestyle in line with their sequenced individual genomes. With this in mind, one of genome-based developments at the junction of personalized medicine and bioinformatics will be considered in this work, where we used two Web services: (i) SNP_TATA_Comparator to search for alleles with a single nucleotide polymorphism (SNP) that alters the affinity of TATA-binding protein (TBP) for the TATA boxes of human gene promoters and (ii) PubMed to look for retrospective clinical reviews on changes in physiological indicators of reproductive potential in carriers of these alleles...

Polycystic ovary syndrome is one of the most common endocrinopathy of the reproductive age. Heterogenity of its clinical symptoms is related to the presence of a number of phenotypes of this disfunction, hence the necessity for individualized treatment is needed. A change of a lifestyle, well-balanced diet and physical activity are the most effective medical way contributing to the improvement of carbohydrate metabolism parameters and weight reduction which reactivates regular ovulation and facilitates getting pregnant...

Introduction Fennel has many medicinal properties and is used in the treatment of dysmenorrhea. Given the widespread use of herbal medicine among women for menstrual problems and considering the fact that there has been no study to date about the effect of fennel on menstrual bleeding and duration of menstrual bleeding through systematic review, the present study was conducted to determine the effect of fennel on the amount (primary outcome) and duration of menstrual bleeding and its side-effects (secondary outcomes)...

BACKGROUND: Daysy is a fertility monitor that uses the fertility awareness method by tracking and analyzing the individual menstrual cycle. In addition, Daysy can be connected to the application DaysyView to transfer stored personal data from Daysy to a smartphone or tablet (IOS, Android). This combination is interesting because as it is shown in various studies, the use of apps is increasing patients´ focus on their disease or their health behavior. The aim of this study was to investigate if by the additional use of an App and thereby improved usability of the medical device, it is possible to enhance the typical-use related as well as the method-related pregnancy rates...
