Menstrual Disorders Practice Questions

Q: The treatment of primary spasmodic dysmenorrhoea in a young girl as a first measure would be:

Analgesics and antispasmodics. ***Analgesics and antispasmodics*** - **NSAIDs (analgesics)** like ibuprofen, naproxen, or mefenamic acid are the **first-line treatment** for primary spasmodic dysmenorrhea - They work by **inhibiting prostaglandin synthesis**, reducing uterine contractions and pain - **Antispasmodics** help relax the uterine muscle and alleviate cramping - Should be started at the onset of menses or just before for maximum effectiveness *Oral contraceptives* - Effective **second-line treatment** by suppressing ovulation and reducing endometrial prostaglandin production - Used when NSAIDs fail or are contraindicated - May be less suitable as a first measure for a young girl, especially if contraception is not desired *Presacral neurectomy* - **Surgical procedure** involving division of the superior hypogastric plexus - Reserved for **severe, refractory cases** that fail conservative management - Major surgery with potential complications—never a first-line option *Dilatation and curettage* - Diagnostic/therapeutic procedure for abnormal uterine bleeding or retained products - **No role in primary dysmenorrhea**, which is functional pain without organic pathology - D&C does not address the prostaglandin-mediated mechanism of primary dysmenorrhea

Q: A 45 year old woman presents with continuous vaginal bleeding for 15 days. Her bleeding should be controlled by:

Synthetic progestogens. ***Synthetic progestogens*** - **Synthetic progestogens** are the **classic first-line medical treatment** for dysfunctional uterine bleeding (DUB) in the perimenopausal age group. - They work by **stabilizing the endometrium**, counteracting unopposed estrogen effects, and inducing organized withdrawal bleeding. - For **continuous moderate bleeding**, cyclic or continuous progestogens (e.g., norethisterone 5 mg BD for 21 days) are effective and non-invasive. - This represents the **traditional textbook approach** for anovulatory DUB management. *Testosterone propionate* - **Testosterone propionate** is an androgen with no role in managing dysfunctional uterine bleeding in women. - Its use is limited to male hypogonadism and specific anabolic requirements. *Curettage followed by progestogens* - While **curettage (D&C)** is both diagnostic and therapeutic, it is an **invasive procedure**. - In clinical practice, especially for a **45-year-old woman**, endometrial sampling is often warranted to rule out hyperplasia or malignancy, making this a reasonable clinical approach. - However, **medical management with progestogens alone** is traditionally considered first-line when the patient is hemodynamically stable and malignancy risk is low. - This option represents sound clinical practice but is not the classic "first choice" in exam contexts. *Conjugated equine oestrogens* - **High-dose estrogens** (25 mg IV every 4-6 hours) are actually used for **acute severe bleeding** and can stop bleeding within 24 hours by rapidly proliferating the endometrium. - However, for **continuous moderate bleeding** over 15 days in a perimenopausal woman, estrogen alone would not address the underlying issue of **unopposed estrogen** causing anovulatory cycles. - Estrogen is reserved for acute emergency management, not for the scenario described in this question.

Q: A 30 year old healthy woman presents with decreased bleeding during menstruation. The cause could be all of the following except:

Endometriosis. ***Endometriosis*** - **Endometriosis** is a condition where endometrial-like tissue grows outside the uterus, typically causing **heavy menstrual bleeding (menorrhagia)**, pelvic pain, and dyspareunia. - It does not typically lead to **decreased menstrual bleeding**; in fact, its cardinal symptom related to menstruation is often an increase in volume and pain. *Intrauterine adhesions* - **Intrauterine adhesions**, also known as **Asherman's syndrome**, involve scarring within the uterine cavity, often resulting from uterine trauma like D&C. - These adhesions can reduce the functional endometrial surface, leading to **hypomenorrhea** or amenorrhea (decreased or absent menstrual bleeding). *Breastfeeding* - **Breastfeeding** (lactational amenorrhea) causes the release of **prolactin**, which inhibits the pulsatile release of GnRH from the hypothalamus. - This suppression of ovarian function leads to **anovulation** and significantly reduced or absent menstrual bleeding. *Tuberculosis* - **Genital tuberculosis** can affect the endometrium, leading to widespread destruction and subsequent fibrosis and **adhesion formation** within the uterine cavity. - This damage to the endometrial lining can result in **asherman's syndrome**, causing hypomenorrhea or amenorrhea.

Q: Which one of the following is the most important haematological condition to be ruled out while investigating a case of puberty menorrhagia ?

Coagulation disorder. ***Coagulation disorder*** - Puberty menorrhagia (excessive menstrual bleeding at puberty) is frequently linked to underlying **hemostatic dysfunction**, with **Von Willebrand Disease** being the most common cause. - A coagulation disorder can lead to **uncontrolled bleeding** during menstruation, necessitating thorough investigation to prevent severe blood loss and complications. *Leukemia* - While leukemia can cause **easy bruising** and **bleeding tendencies** due to thrombocytopenia or impaired platelet function, it is less common as the primary cause of isolated menorrhagia in puberty. - Leukemia would typically present with a broader range of symptoms, including systemic signs like **fatigue**, **fever**, and **lymphadenopathy**. *G-6PD deficiency* - G-6PD deficiency is primarily a cause of **hemolytic anemia**, triggered by certain drugs or foods, leading to red blood cell breakdown. - It does not directly cause prolonged or heavy menstrual bleeding (menorrhagia) as a primary symptom. *Anaemia* - Anaemia is often a **consequence** of heavy menstrual bleeding (menorrhagia) rather than its direct cause. - While iron deficiency anemia is common in young women with menorrhagia, addressing the underlying cause of the bleeding is crucial, which might be a coagulation disorder.

Q: Primary Dysmenorrhoea can be treated by which of the following? 1. Antiprostaglandin 2. Cyclic combined estrogen and progesterone preparations 3. Pre-sacral neurectomy 4. Uterine curettage

1, 2 and 3. ***1, 2 and 3*** - **Antiprostaglandins (NSAIDs)** are the first-line treatment for primary dysmenorrhea as they inhibit prostaglandin synthesis, reducing uterine contractions and pain. - **Cyclic combined estrogen and progesterone preparations (oral contraceptives)** are second-line therapy that suppress ovulation, leading to a thinner endometrium and reduced prostaglandin production, thereby alleviating dysmenorrhea. - **Pre-sacral neurectomy** is a surgical procedure that may be considered for severe, refractory primary dysmenorrhea that has failed medical management, though it is more commonly used for secondary dysmenorrhea and chronic pelvic pain. *1, 2, 3 and 4* - This option incorrectly includes **uterine curettage**, which is not a treatment for primary dysmenorrhea. - Uterine curettage is a diagnostic or therapeutic procedure for conditions like abnormal uterine bleeding or retained products of conception, not for menstrual pain management. *1, 2 and 4* - This option incorrectly includes **uterine curettage** while excluding pre-sacral neurectomy. - Curettage has no role in primary dysmenorrhea treatment, whereas the other interventions target the underlying pathophysiology. *2, 3 and 4* - This option incorrectly excludes **antiprostaglandins (NSAIDs)**, which are the cornerstone first-line therapy for primary dysmenorrhea. - It also incorrectly includes uterine curettage, which has no role in dysmenorrhea management.

Q: Which one of the following conditions simulates the menstrual pattern of pain?

Adenomyosis. ***Adenomyosis*** - Adenomyosis is characterized by the presence of **endometrial tissue within the myometrium**, which responds cyclically to hormonal changes, similar to normal endometrium. - This leads to **dysmenorrhea** (painful periods) and **menorrhagia** (heavy bleeding) due to the cyclic growth and shedding of endometrial tissue within the uterine muscular wall. *Intramural fibroid* - Intramural fibroids are **benign uterine tumors** within the muscular wall that can cause heavy bleeding and pressure symptoms. - While they can cause pain and heavy bleeding, the pain is typically not directly related to a **menstrual pattern of cyclic pain** in the same manner as adenomyosis, as the fibroid tissue itself does not undergo cyclic shedding. *Granulosa cell tumour of ovary* - This is a **sex cord-stromal tumor** of the ovary that often produces **estrogen**, which can lead to irregular uterine bleeding or postmenopausal bleeding. - It does not directly cause pain that simulates a **regular menstrual pattern**, as its hormonal effects are typically sustained or irregular, not cyclic in the way normal menstruation or adenomyosis pain is. *Haematometra* - Haematometra is the accumulation of **menstrual blood within the uterus** due to an obstruction of the outflow tract, such as cervical stenosis. - This condition causes increasing pain and distension as blood accumulates, but the pain is usually **constant or progressively worsening**, not cyclic in a pattern that simulates normal menstruation, and typically leads to **amenorrhea** rather than patterned bleeding.

Q: Which one of the following about primary dysmenorrhea is NOT true?

Pain increases following pregnancy and delivery. ***Pain increases following pregnancy and delivery*** - It is a common clinical observation that primary dysmenorrhea often **improves or resolves** after pregnancy and childbirth, likely due to cervical dilatation, changes in uterine structure, or altered innervation. - Therefore, the statement that pain *increases* following pregnancy and delivery is **NOT true** and is the correct answer. *Most commonly seen in adolescents and young women* - This statement is **TRUE**. Primary dysmenorrhea typically begins within **6-12 months** after menarche once ovulatory cycles are established. - It is **most prevalent in adolescents and women in their 20s**, though it can persist into later reproductive years. - Incidence decreases with age and often improves after childbirth. *Pain is related to uterine hypoxia* - This statement is **TRUE**. The pain in primary dysmenorrhea is primarily caused by **excessive prostaglandin F2α production** during endometrial breakdown. - Prostaglandins cause **intense uterine contractions** leading to **ischemia** and reduced blood flow (hypoxia) to the myometrium. - This **uterine hypoxia** and ischemia are significant contributors to the painful cramps experienced. *Always confined to ovulatory cycles* - This statement is **TRUE**. Primary dysmenorrhea is intrinsically linked to **ovulatory menstrual cycles**. - It involves prostaglandin production in response to progesterone withdrawal and endometrial breakdown, which **only occurs in ovulatory cycles**. - Anovulatory cycles (common immediately after menarche) are typically **painless**.

Q: An 18-year-old unmarried girl comes with complaints of heavy, prolonged bleeding during menses. Which among the following investigations is NOT usually advised?

Dilatation and curettage. ***Dilatation and curettage*** - This is an **invasive surgical procedure** used diagnostically and therapeutically for heavy uterine bleeding, but it is generally *not* the initial or routinely advised investigation for an 18-year-old unmarried girl with heavy menstrual bleeding. - In a young, unmarried patient, less invasive methods are preferred unless other investigations point to a structural abnormality requiring tissue diagnosis or therapeutic intervention. *Urine pregnancy test* - A urine pregnancy test is **essential** to rule out pregnancy-related complications (e.g., ectopic pregnancy, miscarriage) as a cause of heavy vaginal bleeding, even in unmarried individuals. - **Abnormal uterine bleeding** can be the presenting symptom of an early pregnancy loss. *Coagulation profile* - Heavy and prolonged bleeding, especially from a young age (as suggested by "18-year-old girl"), raises suspicion for an **underlying coagulopathy** (e.g., Von Willebrand disease). - A coagulation profile (including PT, aPTT, platelet count, and sometimes specific factor assays) is crucial to **assess bleeding risk** and guide management. *Ultrasound uterus and adnexa* - An ultrasound is a **non-invasive imaging technique** that can identify structural causes of abnormal uterine bleeding, such as **fibroids, polyps, adenomyosis**, or ovarian pathologies. - It helps in assessing the **uterine lining and ovarian morphology**, which is important in evaluating the cause of heavy menstrual bleeding.

Q: Withdrawal bleeding following administration of progesterone in a case of secondary amenorrhea indicates all EXCEPT:

Defect in pituitary gland. ***Defect in pituitary gland*** - While withdrawal bleeding after progesterone suggests the problem lies at the **hypothalamic-pituitary level** (anovulation with adequate estrogen), it does **not definitively rule out all pituitary defects**. - The pituitary may still produce sufficient **FSH to stimulate ovarian estrogen production** but have defective **LH surge mechanism** (WHO Group II anovulation). - Examples include **hyperprolactinemia** or **functional hypothalamic amenorrhea** where estrogen production is preserved despite pituitary-hypothalamic dysfunction. - This is the **EXCEPT answer** because the other options are more definitively confirmed by withdrawal bleeding. *Absence of pregnancy* - Withdrawal bleeding after progesterone administration **definitively confirms absence of pregnancy**. - Pregnancy would prevent withdrawal bleeding due to sustained progesterone production by the corpus luteum and placenta. - This is a key diagnostic exclusion in the evaluation of **secondary amenorrhea**. *Endometrium is responsive to estrogen* - The occurrence of withdrawal bleeding **definitively demonstrates** that the endometrium has been exposed to adequate estrogen and has proliferated. - This proliferative endometrium then sheds when progesterone is withdrawn, confirming **normal endometrial responsiveness to hormonal stimulation**. - This rules out **Asherman syndrome** and other uterine factors. *Production of endogenous estrogen* - Withdrawal bleeding **definitively confirms** that there has been sufficient **endogenous estrogen production** to prime the endometrium. - The estrogen causes endometrial thickening, which then sheds when progesterone is withdrawn. - This indicates **adequate ovarian function** in terms of estrogen synthesis and rules out **hypergonadotropic hypogonadism** (ovarian failure).

Q: Which of the following is not a cause of secondary amenorrhea?

Kallman syndrome. ***Kallman syndrome*** - This is a cause of **primary amenorrhea** because it involves congenital **GnRH deficiency**, preventing the onset of puberty and menstruation from the beginning. - Patients typically present with failure of pubertal development and **anosmia** (inability to smell). *Asherman's syndrome* - Characterized by **intrauterine adhesions** or scarring, often following uterine surgeries like D&C. - These adhesions can prevent the proper shedding of the endometrium, leading to **secondary amenorrhea** after previously established menses. *Sheehan's syndrome* - Occurs due to **ischemic necrosis of the pituitary gland** following severe postpartum hemorrhage, typically presenting with failure of lactation, fatigue, and **secondary amenorrhea**. - The pituitary damage leads to **deficiency of multiple pituitary hormones**, including FSH and LH. *Turner's mosaic* - While classic **Turner syndrome (45,XO)** is a common cause of primary amenorrhea and gonadal dysgenesis, **Turner's mosaic** (e.g., 45,XO/46,XX) can sometimes result in variable ovarian function. - In some mosaic cases, individuals may experience **menarche** and then develop premature ovarian failure, leading to **secondary amenorrhea**.
