DOI: 10.1111/1471-0528.14260 Management of Premenstrual Syndrome This is the second edition of this guideline, which was first published in 2007 under the same title. Executive summary of recommendations How is premenstrual syndrome (PMS) diagnosed? When clinically reviewing women for PMS, symptoms should be recorded prospectively, over two cycles using a symptom diary, as retrospective recall of symptoms is unreliable. A symptom diary should be completed by the patient prior to commencing treatment. Gonadotrophin-releasing hormone (GnRH) analogues may be used for 3 months for a definitive diagnosis if the completed symptom diary alone is inconclusive. [New 2016] What aspects are involved in delivering a service to women with PMS? When should women with PMS be referred to a gynaecologist? Referral to a gynaecologist should be considered when simple measures (e.g. combined oral contraceptives [COCs], vitamin B6, selective serotonin reuptake inhibitors [SSRIs]) have been explored and failed and when the severity of the PMS justifies gynaecological intervention. Who are the key health professionals to manage women with severe PMS? Women with severe PMS may benefit from being managed by a multidisciplinary team comprising a general practitioner, a general gynaecologist or a gynaecologist with a special interest in PMS, a mental health professional (psychiatrist, clinical psychologist or counsellor) and a dietician. [New 2016] How is PMS managed? Are complementary therapies efficacious in treating PMS? fl Women with PMS should be informed that there is con icting evidence to support the use of C some complementary medicines.

Additionally, these women are also under stress due to taboos, myths, inter-personal troubles surrounding infertility and pain of the disease as well as due to frequent incidences of missed diagnosis and treatment recurrence. Often these women suffer from frustration and loss of valuable time in the prime phase of life. All these complexities integral to endometriosis posit a hyperstructure of integrative stress physiology with overt differentials in effective allostatic state in women with disease compared with disease-free women. In the present review, we aim to critically examine various aspects of pathophysiological basis of stress surrounding endometriosis with special emphasis on pain and subfertility that are known to affect the overall health and quality of life of women with the disease and promising pathophysiological basis for its effective management.

Danazol produced a significant benefit with a mean pain score difference À20.23(95% CI À28.12 to À12.34). EPO did not offer any advantage over placebo in pain relief, mean pain score difference being À2.78 (95% CI À7.97 to 2.40).
