Abnormal uterine bleeding is a common symptom in women. The acronym PALM-COEIN facilitates classification, with PALM referring to structural etiologies (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia), and COEIN referring to nonstructural etiologies (coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, not otherwise classified). Evaluation involves a detailed history and pelvic examination, as well as laboratory testing that includes a pregnancy test and complete blood count. Endometrial sampling should be performed in patients 45 years and older, and in younger patients with a significant history of unopposed estrogen exposure. Transvaginal ultrasonography is the preferred imaging modality and is indicated if a structural etiology is suspected or if symptoms persist despite appropriate initial treatment. Medical and surgical treatment options are available. Emergency interventions for severe bleeding that causes hemodynamic instability include uterine tamponade, intravenous estrogen, dilation and curettage, and uterine artery embolization. To avoid surgical risks and preserve fertility, medical management is the preferred initial approach for hemodynamically stable patients. Patients with severe bleeding can be treated initially with oral estrogen, high-dose estrogen-progestin oral contraceptives, oral progestins, or intravenous tranexamic acid. The most effective long-term medical treatment for heavy menstrual bleeding is the levonorgestrel-releasing intrauterine system. Other long-term medical treatment options include estrogen-progestin oral contraceptives, oral progestins, oral tranexamic acid, nonsteroidal anti-inflammatory drugs, and depot medroxyprogesterone. Hysterectomy is the definitive treatment. A lower-risk surgical option is endometrial ablation, which performs as well as the levonorgestrel-releasing intrauterine system. Select patients with chronic uterine bleeding can be treated with myomectomy, polypectomy, or uterine artery embolization.

Abnormal uterine bleeding (AUB) is common, often debilitating, and may affect over 50% of reproductive-aged women and girls. Whereas AUB is a collection of symptoms that include intermenstrual bleeding and abnormalities in period duration, cycle length, and regularity, it is heavy menstrual bleeding (HMB) that is most contributory to iron deficiency and related anemia. It is apparent that AUB, in general, and HMB, in particular, remain underrecognized and underreported. FIGO created two systems for assessing and classifying AUB. FIGO System 1 defines the bleeding pattern using four primary descriptors: frequency, duration, regularity, and flow volume. FIGO System 2 provides a structured classification system of possible causes of AUB, using the acronym PALM-COEIN. "PALM" refers to structural causes of AUB (Polyp, Adenomyosis, Leiomyoma, Malignancy), and "COEI" refers to nonstructural causes (Coagulopathy, Ovulatory dysfunction, Endometrial, and Iatrogenic). The "N" is reserved for those entities that are currently not otherwise classified. Using FIGO System 1 as a gateway to FIGO System 2 streamlines the investigation of reproductive-aged women and girls with AUB. Understanding the pathogenesis of the FIGO System 2 "PALM-COEIN" causes helps interpret investigations and the onward management of AUB. Numerous evidence gaps exist concerning AUB; however, if researchers and trialists universally adopt FIGO Systems 1 and 2 for the assessment and diagnosis of AUB, clear translatable research findings can be applied globally.

Uterine fibroids (UFs) are the most common female benign pelvic tumors, affecting >60% of patients aged 30-44 years. Uterine fibroids are asymptomatic in a large percentage of cases and may be identified incidentally using a transvaginal ultrasound or a magnetic resonance imaging scan. However, in approximately 30% of cases, UFs affect the quality of life and women's health, with abnormal uterine bleeding and heavy menstrual bleeding being the most common complaints, along with iron deficiency (ID) and ID anemia. Medical treatments used for UFs-related abnormal uterine bleeding include symptomatic agents, such as nonsteroidal antiinflammatory drugs and tranexamic acid, and hormonal therapies, including combined oral contraceptives, gonadotropin-releasing hormone agonists or antagonists, levonorgestrel intrauterine systems, selective progesterone receptor modulators, and aromatase inhibitors. Nevertheless, few drugs are approved specifically for UF treatment, and most of them manage the symptoms. Surgical options include fertility-sparing treatments, such as myomectomy, or nonconservative options, such as hysterectomy, especially in perimenopausal women who are not responding to any treatment. Radiologic interventions are also available: uterine artery embolization, high-intensity focused ultrasound or magnetic resonance-guided focused ultrasound, and radiofrequency ablation. Furthermore, the management of ID and ID anemia, as a consequence of acute and chronic bleeding, should be taken into account with the use of iron replacement therapy both during medical treatment and before and after a surgical procedure. In the case of symptomatic UFs, the location, size, multiple UFs, or coexistent adenomyosis should guide the choice with a shared decision-making process, considering long- and short-term treatment goals expected by the patient, including pregnancy desire or wish to preserve the uterus independently of reproductive goals.

Meta-Analysis Review

Authors: Ally Murji, Ari P Sanders, Ilza Monteiro...

OBJECTIVE

To synthesize the published literature to better understand the association between cesarean scar defects (CSDs) and abnormal uterine bleeding (AUB). In particular, we aimed to evaluate the risk and pattern(s) of CSD-associated AUB in addition to exploring the relationship between defect morphology with bleeding symptoms.

DESIGN

Systematic review and meta-analysis.

SETTING

Not applicable.

PATIENTS

Patients with CSD and reports of uterine bleeding as an outcome were identified in 60 studies from database searches.

INTERVENTIONS

Studies that investigated CSD (as defined by investigators) and reported uterine bleeding, menstrual bleeding, or AUB as an outcome were included.

MAIN OUTCOME MEASURES

The prevalence and risk of AUB (intermenstrual, postmenstrual, and unscheduled bleeding) in patients with confirmed CSD.

RESULTS

Nine studies reported on the prevalence of AUB in patients with a confirmed CSD. Patients with CSD were more likely to experience AUB, compared with those without CSD (relative risk, 3.47; 95% confidence interval [CI], 2.02-5.97; 6 studies, 1,385 patients; I = 67%). In a population of patients with at least 1 cesarean delivery, the prevalence of AUB in those with CSD was 25.5% (95% CI, 14.7-40.5; 6 studies, 667 patients, I = 93%). However, symptom prevalence was much higher in patients presenting for imaging for a gynecologic indication where the prevalence of AUB in the presence of a CSD was 76.4% (95% CI, 67.8-83.3; 5 studies, 505 patients; I = 71%). The mean menstrual duration in symptomatic patients with CSD was 13.4 days (95% CI, 12.6-14.2; 19 studies, 2,095 patients; I = 96%), and the mean duration of early-cycle intermenstrual bleeding was 6.8 days (95% CI, 5.7-7.8 days; 9 studies, 759 patients; I = 93%). The most common descriptor of CSD-associated AUB was "brown discharge". Patients with larger CSD experienced more bleeding symptoms.

CONCLUSION

There is a strong and consistent association between patients with CSD and AUB. These patients experience a unique bleeding pattern, namely prolonged menstruation and early-cycle intermenstrual bleeding. These data should provide impetus for including CSD as a distinct entity in AUB classification systems. High heterogeneity in our results calls for standardization of nomenclature and outcome reporting for this condition.

Abnormal uterine bleeding (AUB) is one of the commonest complaints of women in reproductive age and non-gravid state that brings them to the attention of the primary care doctor or the gynaecologist. Anovulation without any medical illness or pelvic pathology seems to be the common cause. Bleeding due to a wide variation in pathology both inside and outside the reproductive tract can be termed as anovulatory bleeding. Therefore, it is mandatory to elicit a focused menstrual history and appropriate evaluation followed by a pelvic examination. This includes a vaginal speculum examination to differentiate anovulatory bleeding from other causes of bleeding. In contrast, Heavy menstrual bleeding (HMB) is referred to as an ovulatory bleeding exceeding 8 days duration and is often caused by uterine fibroids or adenomyosis, a copper IUD or coagulation disorders. PALM-COEIN classification is a system designed by the Federation Internationale de Gynaecologie et d'Obstetrique to define the precise underlying causes of AUB. Aetiology of AUB can be classified as the following acronym "PALM-COEIN": Polyp, Adenomyosis, Leiomyoma, Malignancy and hyperplasia, Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic and Not yet classified. AUB describes a range of symptoms, such as HMB, intermenstrual bleeding (IMB) and a combination of both heavy and prolonged menstrual bleeding (MB). Dysfunctional uterine bleeding (DUB) and menorrhagia are now better described as AUB. Newborn girls sometimes spot for a few days after birth, due to placental oestrogenic stimulation of the endometrium in utero.

Abnormal uterine bleeding is a frequent condition in Gynecology. It may impact physical, emotional sexual and professional aspects of the lives of women, impairing their quality of life. In cases of acute and severe bleeding, women may need urgent treatment with volumetric replacement and prescription of hemostatic substances. In some specific cases with more intense and prolonged bleeding, surgical treatment may be necessary. The objective of this chapter is to describe the main evidence on the treatment of women with abnormal uterine bleeding, both acute and chronic. Didactically, the treatment options were based on the current International Federation of Gynecology and Obstetrics (FIGO) classification system (PALM-COEIN). The etiologies of PALM-COEIN are: uterine Polyp (P), Adenomyosis (A), Leiomyoma (L), precursor and Malignant lesions of the uterine body (M), Coagulopathies (C), Ovulatory dysfunction (O), Endometrial dysfunction (E), Iatrogenic (I), and Not yet classified (N). The articles were selected according to the recommendation grades of the PubMed, Cochrane and Embase databases, and those in which the main objective was the reduction of uterine menstrual bleeding were included. Only studies written in English were included. All editorial or complete papers that were not consistent with abnormal uterine bleeding, or studies in animal models, were excluded. The main objective of the treatment is the reduction of menstrual flow and morbidity and the improvement of quality of life. It is important to emphasize that the treatment in the acute phase aims to hemodynamically stabilize the patient and stop excessive bleeding, while the treatment in the chronic phase is based on correcting menstrual dysfunction according to its etiology and clinical manifestations. The treatment may be surgical or pharmacological, and the latter is based mainly on hormonal therapy, anti-inflammatory drugs and antifibrinolytics.

Abnormal uterine bleeding is a frequent symptom in the perimenopause. Causes are numerous, ranging from physiological reactions due to decreasing/unstable ovarian function to premalignant and malignant conditions. Benign findings such as endometrial polyps and myomas increase with age, leading to more abnormal uterine bleeding in the perimenopause. Cervical and vaginal causes of abnormal uterine bleeding should be excluded by speculum examination. Sexually transmitted diseases or pregnancy should be ruled out. Measurement of haemoglobin and iron levels, human chorion gonadotropin and thyroid hormones are relevant in selected cases. Transvaginal ultrasound is an ideal first step for the evaluation of perimenopausal abnormal uterine bleeding. Saline or gel contrast sonohysterography improves the diagnostic accuracy. Based on the ultrasound findings, invasive procedures such as endometrial biopsy or hysteroscopy can be planned. Once premalignant and malignant causes are excluded, the necessity for treatment can be evaluated in collaboration with the patient. Heavy menstrual bleeding causing anaemia will need immediate treatment. In less severe cases and in intermenstrual bleeding, expectant management can be considered. Hormonal treatment, such as oral progestogens, combined oral contraceptives or insertion of the levonorgestrel intrauterine system, may be a possibility if anovulatory bleeding is interfering with quality of life. The amount of bleeding can be reduced both by antifibrinolytic and non-steroidal anti-inflammatory drugs, progestogens and the levonorgestrel intrauterine system. Focal intrauterine lesions such as endometrial polyps or submucous myomas may require operative hysteroscopic procedures. Endometrial ablation or endometrial resection are good choices in selected cases, but some women will need a hysterectomy to treat their abnormal uterine bleeding in perimenopause.

This article reviews the current understanding and management of abnormal uterine bleeding (AUB) in adolescents. It is hoped that this review will provide readers with an approach to the evaluation and treatment of mild to severe uterine bleeding. AUB is a common problem which has significantly adverse effects on an affected adolescent’s quality of life. The most common underlying condition in AUB in adolescence is anovulation. During the evaluation, pregnancy, trauma and sexually transmitted diseases must be ruled out, regardless of history. It should be kept in mind that AUB during this period may be the first sign of underlying bleeding disorders. Although observation is sufficient in the mild form of AUB, at the other end of the spectrum life-threatening bleeding may necessitate the use of high doses of combined oral contraceptives, intravenous estrogen and/or interventional procedures.

Abnormal uterine bleeding is the most common complaint that motivates female adolescents to seek medical advice. Abnormal uterine bleeding has a significant impact on quality of life, promoting school absenteeism and limitations in social life. Moreover, episodes can vary from mild to life threatening events if not recognized and treated promptly. Healthcare providers should be able to distinguish between a normal and abnormal menstrual pattern, as this may provide early diagnosis of a potential health concern. The PALM-COEIN classification system should be used in the evaluation. Anovulation is the most frequent cause, frequently due to immaturity of the hypothalamic-pituitary-ovarian axis. A careful history and physical examination are crucial in the differential diagnosis. Management is based on both the underlying cause and the severity of bleeding. Most patients improve with pharmacological treatment, frequently requiring a multidisciplinary approach. First line treatment consists of hormonal therapy. Surgery is rarely needed. Although the prevalence of abnormal uterine bleeding is higher in adolescents compared to adults, most recommendations are not specific for this age, which makes the diagnosis and management challenging. The literature reveals lack of standardized care for adolescents and regimens vary widely. Future studies on efficacy and safety of treatments specifically in adolescents are needed.

BACKGROUND

Twenty to forty per cent of pregnant women will experience bleeding during the first trimester. Initial presentation is usually to the general practitioner. Complications of miscarriage, including threatened miscarriage and ectopic pregnancy, are the most common diagnoses. The failure to diagnose an ectopic pregnancy may have life-threatening consequences for a woman.

OBJECTIVE

The aim of this article is to review the history, examination findings, investigations and management options for miscarriage and ectopic pregnancy.

DISCUSSION

Early pregnancy bleeding is a very distressing symptom for which a woman seeks reassurance that she has an ongoing pregnancy. It is not always possible to make a diagnosis at the first presentation. In some cases, the need for follow-up investigations or referral to a gynaecologist is required. As healthcare providers, we should continue to review and update our knowledge in the management of this common presentation in order to optimise our care of these patients.
