menstrual - Anormalities
menstrual cycle abnormalities diagram
A multi-panel pathophysiology diagram illustrating the synchronous physiological changes during a standard 28-day human menstrual cycle. The top panel graphs gonadotropin levels, showing a sharp surge in Luteinizing Hormone (LH) and a moderate rise in Follicle-Stimulating Hormone (FSH) at day 14, correlating with the follicular phase, ovulation, and luteal phase stages. The corresponding follicular development shows the maturation of a primary follicle into a Graafian follicle, ovulation, and the formation of the corpus luteum and corpus albicans. The middle panel tracks plasma sex hormone levels, highlighting the mid-cycle peak of Estradiol (E2) and the post-ovulatory rise of Progesterone (P4). The bottom panel depicts endometrial morphology, transitioning from the menstrual phase to the proliferative and secretory phases. A green-shaded layer highlights the glycocalyx development, which thickens and becomes most prominent during the secretory phase under the influence of P4, before thinning during menstruation. The diagram demonstrates the hormonal regulation of the ovary and uterine lining for medical educational purposes.
A multi-panel neuroimaging diagram illustrating effective connectivity differences across the menstrual cycle within a triple-network model. The networks include the Default Mode Network (DMN), Salience Network (SN), and Executive Control Network (ECN). The panels (a-f) represent directed connectivity between networks: DMN to SN, SN to DMN, DMN to ECN, ECN to DMN, SN to ECN, and ECN to SN. Results are categorized into three cycle phase comparisons: Pre-ovulatory vs. Early Follicular, Luteal vs. Early Follicular, and Luteal vs. Pre-ovulatory. Brain regions are depicted as colored nodes (e.g., mPFC, PCC, ACC, AI, MFG, SMG) on axial schematic brain templates. Arrows indicate the direction and strength (width) of connectivity differences. Black arrows represent positive differential connectivity, while red arrows represent negative differential connectivity. Asterisks denote connections with high statistical significance (posterior probability >95%). This resource facilitates understanding of how endogenous hormonal fluctuations modulate functional brain architecture and inter-network communication in healthy adult females.
This pathophysiology diagram illustrates hallmarks of major depressive disorder (MDD) across various stages of the female reproductive lifespan, including reproductive age, pregnancy, and peri- and postmenopause. A line graph labeled 'Physiological Hormonal Fluctuations' depicts the 28-day menstrual cycle, showing estrogen peaks prior to ovulation (Day 14) and progesterone dominance during the luteal phase. A signaling pathway shows how progesterone fluctuations lead to GABA and serotonin receptor modulation, contributing to premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD). In the pregnancy/postpartum pathway, reduced allopregnanolone levels and GABA alterations are linked to postpartum depression (PPD). The peri- and postmenopausal section illustrates declining estradiol (E2) and progesterone, linked to the intensification of depressive symptoms. The diagram also highlights secondary factors, including impaired estrobolome function (gut-microbiome-estrogen axis) involving bacteria like Prevotella and Ruminococcus, and an immune component characterized by attenuated microglia and inflammatory responses compared to men. This visualization integrates endocrinology, neurobiology, and immunology to explain sex-specific vulnerabilities in mood disorders.
This composite educational graphic illustrates the morphological and hormonal changes of the human endometrium across a standard 28-day uterine cycle. The top section features a pathophysiology diagram showing fluctuations in estradiol (E2) and progesterone (P). E2 peaks during the proliferative phase, correlating with endometrial growth, while P dominates the secretory phase, driving glandular coiling and the 'window of implantation' (WOI). Below the hormone curves, a cross-sectional illustration depicts the histological evolution of endometrial glands and spiral arteries. It transitions from a thin, shedding layer in the menstrual phase to elongated glands during the proliferative phase, and finally to highly coiled, secretory glands with increased angiogenesis in the secretory phase. The bottom section displays three diagnostic ultrasound images of the uterus, providing clinical correlation of endometrial thickness: 2 mm (early proliferative), 11 mm (late proliferative), and 14 mm (mid-secretory). Key physiological processes such as post-menstrual repair, cellular proliferation, angiogenesis, and stromal decidualization are annotated to link hormonal signaling with macroscopic and microscopic changes.

Summary : This flowchart outlines the classification and causes of comitant strabismus, dividing cases based on the presence or absence of diplopia, and further categorizing by horizontal or vertical deviation and specific etiologies. flowchart: # Nodes : • Comitant (root node, rectangle) • Diplopia (rectangle) • Horizontal (rectangle) • ET (rectangle) • Decompensated E (rectangle) • Age-related (rectangle) • Divergence insuff (rectangle) • TED (rectangle) • Sagging eye (rectangle) • Fixation switch (rectangle) • Post retinal surgery (rectangle) • XT (rectangle) • Decompensated X (rectangle) • CI (rectangle) • MG (rectangle) • TED (rectangle) • Vertical (rectangle) • Decompensated H (rectangle) • Skew (rectangle) • MG (rectangle) • TED (rectangle) • No diplopia (rectangle) • Sensory (rectangle) • Recurrent childhood strabismus (rectangle) # Connectors : • Comitant splits into Diplopia and No diplopia. • Diplopia splits into Horizontal and Vertical. • Horizontal splits into ET and XT. • ET leads to Decompensated E, which branches into Age-related, Divergence insuff, TED, Sagging eye, Fixation switch, and Post retinal surgery. • XT leads to Decompensated X, CI, MG, and TED. • Vertical leads to Decompensated H, Skew, MG, and TED. • No diplopia leads to Sensory, which leads to Recurrent childhood strabismus. # Layout : • Hierarchical, top-down tree structure. • Main branches: Diplopia (left, subdivided into Horizontal and Vertical) and No diplopia (right, subdivided into Sensory). # Analysis : • The flowchart systematically categorizes comitant strabismus based on diplopia presence, then by deviation direction (horizontal/vertical), and finally by specific etiologies. • Multiple causes are listed for each subtype, highlighting the complexity and variety of underlying mechanisms. • TED (Thyroid Eye Disease) and MG (Myasthenia Gravis) appear as causes in both horizontal and vertical diplopia, indicating their broad impact. • The "No diplopia" branch is much simpler, focusing on sensory causes and recurrent childhood strabismus.
Summary : This flowchart presents the updated nomenclature and classification of Steatotic Liver Disease (SLD), breaking it down into four main categories based on underlying causes and risk factors, including metabolic dysfunction, alcohol intake, and other etiologies. flowchart: # Nodes : • Steatotic Liver Disease (SLD) (main category, leftmost node with icon) • MASLD (Metabolic dysfunction–associated steatotic liver disease) (blue rectangle) – Steatosis with ≥1 cardiometabolic risk factors: • Prediabetes or diabetes • Overweight or obesity • Dyslipidemia (or on lipid-lowering therapy) • Hypertension (or on BP-lowering medication) • MetALD (MASLD with increased alcohol intake) (dark red rectangle) – MASLD in the setting of increased alcohol consumption (between 20 and 50 g/day in women and 30 and 60 g/day in men) • ALD (Alcohol-associated liver disease) (orange rectangle) – Steatosis in the setting of sustained increased alcohol consumption (>50 g/day in women and >60 g/day in men) • Other Causes of SLD (gray rectangle) – Known causes: drug-induced steatosis, monogenic SLD, and others – Cryptogenic: unknown – Steatosis without cardiometabolic risk factors or without excessive alcohol use (future MASLD?) # Connectors : • SLD branches rightward into four categories: MASLD, MetALD, ALD, and Other Causes of SLD. • Each category is connected with a rightward arrow from SLD. • MetALD and ALD are sequentially related by alcohol intake thresholds. # Layout : • Vertical stack of four colored rectangles (MASLD, MetALD, ALD, Other Causes of SLD) to the right of the main SLD node. • Arrows point from the main SLD node to each category. • Explanatory bullet points within each rectangle. # Analysis : • The flowchart clarifies the new classification of SLD, distinguishing between metabolic and alcohol-related causes. • MASLD is defined by the presence of metabolic risk factors, while MetALD and ALD are differentiated by levels of alcohol intake. • "Other Causes" captures less common or unknown etiologies. • The structure emphasizes the importance of both metabolic and alcohol-related factors in the diagnosis and categorization of steatotic liver disease.
Summary : This flowchart presents a revised classification of myocardial infarction (MI) based on the presence or absence of acute coronary occlusion and the underlying mechanisms, as adapted from de Lemos et al. It visually distinguishes between MI with acute coronary occlusion and MI due to oxygen supply/demand mismatch without acute coronary occlusion, further subdividing each category by specific pathophysiological causes. flowchart: # Main Categories : • Acute myocardial injury with signs and/or symptoms of ischaemia (top-level node). • Two primary branches: – MI with acute coronary occlusion. – MI due to oxygen supply/demand mismatch without acute coronary occlusion. # MI with Acute Coronary Occlusion (Left Branch) : • Plaque rupture/erosion with thrombus (circular illustration showing narrowed artery with thrombus). • Spontaneous coronary artery dissection (circular illustration showing dissection in artery wall). • Coronary embolism (circular illustration showing embolic obstruction). • Vasospasm or microvascular dysfunction (circular illustration showing narrowed vessel due to spasm). # MI Due to Oxygen Supply/Demand Mismatch Without Acute Coronary Occlusion (Right Branch) : • With fixed obstructive CAD (circular illustration showing narrowed artery with stable plaque). • Without fixed obstructive CAD (circular illustration showing normal or non-obstructed artery). # Connectors : • Downward arrows from the top node to the two main branches. • Further downward arrows from each main branch to their respective subcategories. # Layout : • Hierarchical, top-down structure. • Two main branches split horizontally, each with multiple subcategories depicted with icons/illustrations. # Technical Details : • Figure legend notes that both MI types may present with ECG changes of ST-segment elevation (STEMI) or non-ST-segment elevation (NSTEMI). • Abbreviations: CAD = coronary artery disease; MI = myocardial infarction. Analysis : • The flowchart clarifies that MI can result from either acute coronary occlusion (with several distinct mechanisms) or from an imbalance in oxygen supply and demand without acute occlusion, with or without underlying coronary artery disease. • Visual icons help differentiate the pathophysiological processes, emphasizing the heterogeneity of MI causes. • The structure supports clinical differentiation for diagnosis and management.
Menstrual Abnormalities
1. Classification & Terminology
| Term | Definition |
|---|---|
| Amenorrhea | Absence of menstrual periods |
| Oligomenorrhea | Reduced frequency of periods (cycles >38 days) |
| Hypomenorrhea | Scanty flow during regular periods |
| Menorrhagia (HMB) | Abnormally heavy/prolonged flow during regular periods |
| Metrorrhagia | Bleeding from the uterus between periods (intermenstrual) |
| Menometrorrhagia | Heavy, irregular bleeding |
| Dysmenorrhea | Painful menstruation |
| PMS / PMDD | Premenstrual syndrome / premenstrual dysphoric disorder |
Note: Older terms like menorrhagia, metrorrhagia, and "dysfunctional uterine bleeding" have been largely replaced by the PALM-COEIN classification system (FIGO, 2011) for abnormal uterine bleeding (AUB).
2. Abnormal Uterine Bleeding (AUB) - PALM-COEIN
- P - Polyps
- A - Adenomyosis
- L - Leiomyoma (fibroids)
- M - Malignancy and hyperplasia
- C - Coagulopathy
- O - Ovulatory dysfunction
- E - Endometrial causes
- I - Iatrogenic (medications)
- N - Not otherwise classified
AUB causes by age group (Robbins):
- Prepuberty: Precocious puberty (hypothalamic, pituitary, or ovarian origin)
- Adolescence: Anovulatory cycles, coagulation disorders
- Reproductive age: Pregnancy complications, structural lesions (polyps, fibroids), anovulation, coagulopathy
- Perimenopausal: Anovulatory cycles (due to HPO axis fluctuations)
- Postmenopausal: Atrophy (most common), endometrial malignancy
3. Amenorrhea
Primary vs. Secondary
- Primary amenorrhea: Menstrual bleeding has never occurred. May be associated with absent secondary sexual characteristics.
- Secondary amenorrhea: Cessation of previously normal menstrual cycles. The most common cause is pregnancy ("secondary amenorrhea should be considered due to pregnancy until proved otherwise").
Causes of Amenorrhea (Berek & Novak's Gynecology):
- Hypergonadotropic hypogonadism (e.g., Turner syndrome - 45,X)
- Hypogonadotropic hypogonadism
- Kallmann syndrome (GnRH deficiency + anosmia)
- GnRH/FSH/LH receptor defects
- Aromatase deficiency
- Outflow tract / Müllerian anomalies (e.g., imperforate hymen, Mayer-Rokitansky-Küster-Hauser syndrome)
- Androgen insensitivity syndrome
- Ovotesticular disorder of sexual development
- Polycystic Ovarian Syndrome (PCOS) - most common endocrine cause
- Hyperprolactinemia (pituitary adenoma, drug-induced)
- Primary Ovarian Insufficiency (premature ovarian failure)
- Hypothalamic amenorrhea - excess opioid activity slows GnRH pulse frequency; associated with:
- Eating disorders / weight loss
- Excessive exercise
- Stress / emotional stimuli
- Obesity
- Thyroid disorders
- Other hypothalamic/pituitary lesions
Key mechanism in hypothalamic amenorrhea: GnRH pulse frequency is slowed by excess opioid activity in the hypothalamus. Naltrexone (an opioid blocker) has shown encouraging results in restoring GnRH pulse frequency. - Ganong's Review of Medical Physiology
4. Dysfunctional Uterine Bleeding (DUB)
- At menarche (first 1-2 years)
- In the perimenopausal period
- Pituitary tumors secreting prolactin (disrupts GnRH → ↓LH and FSH)
- PCOS or functioning ovarian tumors (e.g., granulosa cell tumors)
- Obesity, malnutrition, or chronic systemic disorders
- Luteal phase defect (insufficient progesterone from corpus luteum)
5. Dysmenorrhea
- Primary dysmenorrhea: No identifiable pathology; due to excess prostaglandins (PGE2) in the uterus causing myometrial contractions and ischemia. Common in young women; often decreases after first pregnancy.
- Secondary dysmenorrhea: Due to an underlying condition (endometriosis, fibroids, adenomyosis, pelvic inflammatory disease).
Treatment of Dysmenorrhea (Harrison's, 22nd Ed.):
- NSAIDs (ibuprofen, naproxen, ketoprofen, mefenamic acid) - most effective (>80% response rate). Best started before onset of menses and continued 2-3 days.
- Combined or progestin-only oral contraceptives (cyclic or continuous)
- Vitamin B1 (100 mg/day), magnesium, omega-3 fatty acids - adjunct evidence
- Heat application, exercise, yoga - modest benefit
- Endometriosis-related: GnRH agonists with add-back therapy, aromatase inhibitors, laparoscopic resection
6. Premenstrual Syndrome (PMS) / PMDD
- Irritability, bloating, edema
- Decreased concentration, depression
- Headache, breast tenderness, constipation
- SSRIs (e.g., fluoxetine) - first-line for PMDD (serotonin mechanism)
- Benzodiazepines (alprazolam) - for anxiety/irritability
- GnRH agonists (in doses that suppress the pituitary-ovarian axis) - effective for severe cases
- Calcium, magnesium supplementation
7. Diagnostic Workup for AUB
- Detailed history + pelvic exam
- Pregnancy test (first step)
- CBC, thyroid function, prolactin level
- Cervical cancer screening (Pap smear)
- STI screening
- Pelvic ultrasound
- Endometrial biopsy - indicated for:
- Age ≥45 with AUB
- <45 with risk factors (obesity, unopposed estrogen, persistent AUB, family history of endometrial cancer)
- Coagulation screening - if heavy bleeding since menarche, family history, medication-related
8. Treatment Summary
| Condition | First-Line Treatment |
|---|---|
| Anovulatory AUB | Hormonal therapy (OCP, progestin, LNG-IUD) |
| Endometrial hyperplasia | Progestins, IUD; surgery if high-grade |
| Fibroids | Medical (NSAIDs, tranexamic acid, GnRH agonists); surgical (myomectomy, UAE, ablation) |
| Primary dysmenorrhea | NSAIDs, COCs |
| Hypothalamic amenorrhea | Address underlying cause; pulsatile GnRH, naltrexone |
| PMS/PMDD | SSRIs (fluoxetine), alprazolam, GnRH agonists |
| PCOS-related | OCP, metformin, lifestyle modification |
