INTRODUCTION:
Premature ovarian insufficiency (POI) refers to loss of ovarian activity before the age 40 years. POI has significant detrimental effects on health (infertility, cardiovascular diseases, type 2 diabetes, reduced bone density, dementia), well-being and longevity. This summary is a practical toolkit for health-care professionals (HCPs) looking after women with POI.
METHOD:
A workgroup comprising specialists in gynaecology, reproductive medicine, endocrinology, genetics and family medicine reviewed relevant guidelines and literature on POI to establish recom-mendations for the diagnosis and management of POI in Singapore.
RESULTS:
A summary to assist HCPs manage POI was produced, outlining: (1) the aetiology and conse-quences of POI; (2) making the diagnosis; (3) hormone therapy (HT) prescribing options including for those with additional medical conditions; (4) counselling women with POI about HT; and (5) long-term management of POI.
CONCLUSION
Timely diagnosis and management of POI is vital to prevent long-term adverse consequences, except infertility. HT is the mainstay of treatment and there are no alternatives as effective. Contraindications are very few; estrogen-sensitive cancer is the main contraindication, and caution in prescribing may be needed with established coexisting cardiovascular disease. Estrogen dosage is higher than when treating normal menopause, and as a result, the patient might require more progestogen for endometrial protection. Minimising cardiovascular risk factors by following a healthy lifestyle is important. POI is a significant public health issue and it is imperative that women have affordable access to appropriate HT. Large-scale research on POI in Asian women is needed.

We present a case series of four patients with Caesarean scar pregnancies (CSPs) managed at our gynaecological unit between October 2008 and May 2009. Three patients were detected while asymptomatic, and were treated with elective intragestational sac methotrexate injections. The last patient had presented following complications from a termination of pregnancy for a CSP that was misdiagnosed as intrauterine. Following treatment, this patient and another developed arteriovenous malformation, which responded to bilateral uterine artery embolisations and gonadotropin releasing hormone (GnRH)-agonist treatment.

INTRODUCTIONPathologically adherent placentas occur when there is a defect of the decidua basalis, typically arising from previous caesarean section, resulting in abnormally invasive implantation of the placenta. The depth of placental invasion varies from the superficial (accreta), to transmural and possibly beyond (percreta).
CLINICAL PICTUREWe report on 2 cases, one treated "conservatively", the other with a caesarean hysterectomy, both of which led to a safe outcome for both mother and baby.
CONCLUSIONSManagement relies on accurate early diagnosis with appropriate perioperative multidisciplinary planning to anticipate and avoid massive obstetric haemorrhage at delivery.
