Abnormal uterine bleeding is one of the most common presentations in gynecology practice with too many causes. Acute promyelocytic leukemia is one of the serious causes of uterine hemorrhage. Frequency and severity of hemorrage seen in acute promyelocytic leukemia is often associated with disseminated intravascular coagulation which can be life-threatening. A 37-year-old women was admitted to the emergency room with acute severe uterine bleeding, increasing weakness and weight loss. There was no gynecologic pathology that could clarify the situation. High suspicion of acute promyelocytic leukemia was noticed during evaluation. All-trans retinoic acid treatment with aggressive blood product support was started immediately. Pathological examination of sternal bone marrow confirmed the suspicions. Our aim is to report a case of massive uterine hemorrhage leading to diagnosis of acute promyelocytic leukemia for the first time and to take attention on acute promyelocytic leukemia as a very rare cause of uterine hemorrhage. Key words: Uterine hemorrhage, thrombocytopenia, acute promyelocytic leukemia, anemia 1. Introduction Adverse drug effects, nutritional deficiencies, renal insufficiency, hepatic abnormalities, Abnormal uterine bleeding (AUB) is one of the vasculitis and especially hematologic disorders most common presentations in gynecology could be the reason for abnormal uterine practice. It is estimated that at least 5–10% of bleeding.

  • Abnormal Uterine Bleeding: a Management Algorithm
    J Am Board Fam Med: first published as 10.3122/jabfm.19.6.590 on 7 November 2006. Downloaded from EVIDENCED-BASED CLINICAL MEDICINE Abnormal Uterine Bleeding: A Management Algorithm John W. Ely, MD, MSPH, Colleen M. Kennedy, MD, MS, Elizabeth C. Clark, MD, MPH, and Noelle C. Bowdler, MD Abnormal uterine bleeding is a common problem, and its management can be complex. Because of this complexity, concise guidelines have been difficult to develop. We constructed a concise but comprehen- sive algorithm for the management of abnormal uterine bleeding between menarche and menopause that was based on a systematic review of the literature as well as the actual management of patients seen in a gynecology clinic. We started by drafting an algorithm that was based on a MEDLINE search for rel- evant reviews and original research. We compared this algorithm to the actual care provided to a ran- dom sample of 100 women with abnormal bleeding who were seen in a university gynecology clinic. Discrepancies between the algorithm and actual care were discussed during audiotaped meetings among the 4 investigators (2 family physicians and 2 gynecologists). The audiotapes were used to revise the algorithm. After 3 iterations of this process (total of 300 patients), we agreed on a final algorithm that generally followed the practices we observed, while maintaining consistency with the evidence. In clinic, the gynecologists categorized the patient’s bleeding pattern into 1 of 4 types: irregular bleeding, heavy but regular bleeding (menorrhagia), severe acute bleeding, and abnormal bleeding associated with a contraceptive method. Subsequent management involved both diagnostic and treatment interven- tions, which often occurred simultaneously.

These fistulas can be a challenging condition to treat. Although most fistulas can be treated with surgical repair, for those patients who are not operative candidates, limited options remain. As minimally-invasive interventional techniques have evolved, the possibility of fistula occlusion has enriched the therapeutic armamentarium for the treatment of these complex patients. In order to offer optimal treatment options to these patients, it is important to understand the imaging and anatomical features which may appropriately guide the surgeon and/or interventional radiologist during pre-procedural planning. Keywords: colorectal-vaginal fistula; fistula; percutaneous fistula repair 1. Review of Current Literature on Vaginal Fistulas Vaginal fistulas account for some of the most distressing symptoms seen by clinicians today. The symptomatology of vaginal fistulas is related to the type of fistula; these include rectovaginal, anovaginal, colovaginal, enterovaginal, vesicovaginal, ureterovaginal, and urethrovaginal fistulas, with the two most common types reported as being vesicovaginal and rectovaginal [1].

  • ASCCP Clinical Practice Statement Evaluation of the Cervix in Patients with Abnormal Vaginal Bleeding Published: February 7, 2017
    ASCCP Clinical Practice Statement Evaluation of the Cervix in Patients with Abnormal Vaginal Bleeding Published: February 7, 2017 All women presenting with abnormal vaginal bleeding should receive evaluation of the cervix and vagina, which should include at minimum visual inspection (speculum exam) and palpation (bimanual exam). If cervical or vaginal lesions are noted, appropriate tissue sampling is recommended, which can include Pap testing in addition to biopsy with or without colposcopy. These recommendations concur with those of ACOG Practice Bulletin #128 and Committee Opinion #557.1,2 The purpose of this article is to remind clinicians that Pap testing, as a form of tissue sampling, can be an important part of the workup of abnormal bleeding, and can be performed even if the patient is not due for her next screening test if there is clinical concern for cancer. Due to confusion amongst clinicians that has come to our attention, we wish to highlight the distinction between recommendations for diagnosis of cervical abnormalities including cancer amongst women with abnormal bleeding and recommendations for screening for cervical cancer amongst asymptomatic women. Screening guidelines recommend Pap testing at 3 year intervals for women ages 21-29, and Pap and HPV co-testing at 5 year intervals between the ages of 30-65 (with continued Pap testing at 3 year intervals as an option). These evidence- based guidelines are designed to maximize the detection of pre-cancer and minimize colposcopies. In addition, clinical practice guidelines no longer support routine pelvic examinations for cancer screening in asymptomatic women as this has not been shown to prevent cancer deaths.3,4,5 Consequently, physicians now perform fewer pelvic exams.

OBJECTIVE [email protected]. This article outlines a general approach to such patients and discusses the diagnostic possibilities and their edu.au management. DISCUSSION The most common cause of postmenopausal bleeding is atrophic vaginitis or endometritis. However, as 10% of women with postmenopausal bleeding will be found to have endometrial cancer, all patients must be properly assessed to rule out the diagnosis of malignancy. Most women with endometrial cancer will be diagnosed with early stage disease when the prognosis is excellent as postmenopausal bleeding is an early warning sign that leads women to seek medical advice. Postmenopausal bleeding (PMB) is defined as bleeding • cancer of the uterus, cervix, or vagina (Table 1). that occurs after 1 year of amenorrhea in a woman Endometrial or vaginal atrophy is the most common cause who is not receiving hormone therapy (HT). Women of PMB but more sinister causes of the bleeding such on continuous progesterone and oestrogen hormone as carcinoma must first be ruled out. Patients at risk for therapy can expect to have irregular vaginal bleeding, endometrial cancer are those who are obese, diabetic and/ especially for the first 6 months.

  • Abnormal Uterine Bleeding
    Abnormal Uterine Bleeding in Premenopausal Women Noah Wouk, MD, Piedmont Health Services, Prospect Hill, North Carolina Margaret Helton, MD, University of North Carolina School of Medicine, Chapel Hill, North Carolina 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 non- structural 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 sig- nificant 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,

  • A Case of Adenomyosis During Pregnancy Requiring Cesarean Hysterectomy
    Case Report Journal of Clinical Obstetrics, Gynecology & Infertility Published: 13 Apr, 2018 A Case of Adenomyosis during Pregnancy Requiring Cesarean Hysterectomy Gordon C*, Hartenstine J and Tatsis V Department of Obstetrics & Gynecology, University of California, USA Abstract Background: Adenomyosis occurs when endometrial tissue is found within the myometrium. The risks of adenomyosis in pregnancy are well described and include preterm delivery and preterm premature rupture of membranes, however only a few case reports describe the risks of delivery in the setting of extensive adenomyosis. Case Presentation: We report the case of a 36-year-old G2P0010 at 38 week and 4 days gestation who presented in labor. The fetus was in the breech presentation so she underwent a primary Cesarean section. At the time of surgery, extensive transmural adenomyosis with decidualization was noted, ultimately requiring a Cesarean hysterectomy due to intra-operative hemorrhage. Conclusion: This case emphasizes the importance of early clinical suspicion of adenomyosis in pregnancy to mitigate potentially life-threatening hemorrhage. Keywords: Transmural adenomyosis; Cesarean hysterectomy; Obstetrical emergency Introduction Adenomyosis is defined as the presence of endometrial tissue within the myometrium. Phenotypically, adenomyosis commonly manifests as an enlarged, globular uterus that can result in heavy menstrual bleeding and dysmenorrhea but is often asymptomatic [1]. The true prevalence of the disease is difficult to ascertain because the definitive diagnosis can only be made at the time of histologic assessment of hysterectomy specimens. Nonetheless, prior studies have described OPEN ACCESS adenomyosis rates up to 50% of uterine ultrasound studies in gynecology patients [2]. There is an association between adenomyosis and adverse pregnancy outcomes, including preterm delivery *Correspondence: and Preterm Premature Rupture of Membranes (PPROM) [3].
