A Pap smear, also called a Pap test or cervical cytology, is a screening test for cervical cancer and its precancerous changes. During a pelvic examination, a clinician gently collects cells from the cervix using a small brush. The laboratory examines the cells under a microscope. Cervical cytology can identify epithelial abnormalities before they develop into cancer.

What it detects

Normal cervical cells
Cell changes often caused by high-risk human papillomavirus (HPV)
Precancerous lesions
Occasionally, cervical cancer

It is a screening test, not a definitive diagnosis. An abnormal result may require repeat testing, an HPV test, or colposcopy with possible biopsy.

Typical screening schedule in the United States

For people with a cervix at average risk:

Age 21-29: Pap test every 3 years.
Age 30-65: one of these options:
- Pap test every 3 years
- High-risk HPV test every 5 years
- Pap plus HPV co-testing every 5 years

Screening usually does not begin before 21 or continue after 65 when there has been adequate prior normal screening and no high-risk factors. The schedule differs for people with prior abnormal tests, HIV/immunosuppression, past cervical precancer/cancer, or prenatal DES exposure. CDC summary of screening intervals

Preparation

For the most reliable sample, usually avoid vaginal intercourse, douching, and vaginal creams or medicines for about 24-48 hours beforehand, unless your clinician advises otherwise. It can be done during menstruation in some settings, but a heavy period may lead to rescheduling.

Common report terms

NILM: Negative for intraepithelial lesion or malignancy, meaning no precancerous or cancerous cells seen.
ASC-US: Atypical squamous cells of undetermined significance.
LSIL: Low-grade squamous intraepithelial lesion, commonly HPV-related.
HSIL: High-grade squamous intraepithelial lesion, with a higher chance of significant precancer.

Cervical cytology results are commonly reported through the Bethesda system. Histology: A Text and Atlas with Correlated Cell and Molecular Biology, p. 2299.

Can you make short gynaecology and obstruction notes for my exam last moment revise

Reading File

This is a broad last-minute revision area. I can make a compact, high-yield sheet, but “obstruction” can mean different things in obstetrics.

Core gynaecology
- Menstrual disorders and AUB
- Fibroid, endometriosis, adenomyosis
- PID and vaginal discharge
- Infertility and contraception
- Prolapse and urinary incontinence
- Cervical, ovarian, and endometrial cancers
- Gynaecologic emergencies: ectopic pregnancy, ovarian torsion
Obstetric obstruction
- Cephalopelvic disproportion (CPD)
- Malpresentation and malposition
- Obstructed labour: diagnosis, complications, and management
- Partograph and referral
If you meant intestinal obstruction
- Causes, features, X-ray findings, fluid resuscitation, surgery indications

For a final revision, I would use definitions, key differentiating points, diagnostic clues, first-line management, and one-line complications rather than detailed theory.

Which notes do you need?

Overall every single topic

A complete last-minute gynaecology plus obstetric-obstruction revision set is too large to safely compress into one useful message without knowing your syllabus. Here is the full exam-oriented map:

General gynaecology
- Puberty and menstrual physiology
- Amenorrhoea, dysmenorrhoea, premenstrual syndrome
- Abnormal uterine bleeding and PALM-COEIN
- Vaginal discharge, PID, genital tuberculosis
- Fibroid, adenomyosis, endometriosis
- Ovarian cysts, PCOS, ovarian tumours
- Infertility and assisted reproduction
- Contraception and medical termination of pregnancy
- Urogynaecology: prolapse, urinary incontinence, fistula
- Benign and malignant disease of vulva, vagina, cervix, uterus, ovary
- Gynaecological emergencies: ectopic pregnancy, torsion, ruptured cyst, acute PID
Obstetrics relevant to obstruction
- Normal labour and mechanism of labour
- Pelvis, fetal skull, diameters, engagement
- Partograph
- Malpositions: occipitoposterior, occipitotransverse
- Malpresentations: breech, face, brow, transverse lie, compound presentation
- CPD and contracted pelvis
- Obstructed labour: causes, diagnosis, management, complications
- Instrumental delivery and caesarean section
- Rupture uterus, postpartum haemorrhage, puerperal sepsis
General surgery intestinal obstruction, if included in your exam
- Small versus large bowel obstruction
- Adhesions, hernia, volvulus, malignancy, intussusception
- Symptoms, X-ray/CT features, resuscitation, indications for surgery
- Strangulation and perforation

High-yield principle: for every condition, revise in this sequence: definition → risk factors/causes → clinical features → investigations → management → complications.

State your exam and level (for example MBBS, BSc Nursing, GNM, DGO) and whether “obstruction” means obstructed labour only or also intestinal obstruction. Then I will create a concise all-topic revision sheet matched to that syllabus.

"Abnormal Uterine Bleeding" AND management

Searching the Web

ACOG abnormal uterine bleeding amenorrhea dysmenorrhea guidance

MBBS OBG Last-Minute Notes: Part 1 - Core Gynaecology

1. Menstrual cycle

Normal menstruation

Cycle interval: usually 21-35 days
Duration: 2-7 days
Average blood loss: about 30-40 mL. Heavy menstrual bleeding is suggested by flooding, clots, changing protection very frequently, or anaemia.
Menarche usually occurs 2-3 years after thelarche.

Phases

Ovarian cycle	Endometrial cycle	Main hormone/event
Follicular phase	Proliferative phase	FSH stimulates follicles; estrogen proliferates endometrium
Ovulation	Late proliferative	LH surge causes ovulation, about 14 days before next period
Luteal phase	Secretory phase	Corpus luteum produces progesterone
Luteolysis	Menstruation	Fall in estrogen and progesterone causes shedding

High-yield: Progesterone causes secretory changes and raises basal body temperature by about 0.3-0.5°C after ovulation.

2. Amenorrhoea

Definitions

Primary amenorrhoea: no menstruation by 15 years in a girl with normal secondary sexual characteristics, or by 13 years if secondary sexual characteristics are absent.
Secondary amenorrhoea: absence of menses for 3 months in someone with previously regular cycles, or for 6 months if cycles were irregular. ACOG definition

Primary amenorrhoea: approach

Step 1: Is uterus present? Use USG

Uterus absent

Müllerian agenesis (MRKH): normal breasts, scant/absent pubic hair? Typically normal pubic hair, 46,XX.
Androgen insensitivity syndrome: normal breasts, absent/scant pubic and axillary hair, 46,XY, undescended testes.

Uterus present

Outflow obstruction: imperforate hymen, transverse vaginal septum
- Cyclical pelvic pain + primary amenorrhoea + hematocolpos
Gonadal dysgenesis, e.g. Turner syndrome
- No secondary sexual characters, streak ovaries, raised FSH
Hypothalamic-pituitary causes

Primary amenorrhoea mnemonic

“Breasts? Uterus? FSH?”

Breasts present or absent?
Uterus present or absent?
If uterus present, FSH high or low?

Secondary amenorrhoea: causes and evaluation

Most important first step

Exclude pregnancy with urine/serum beta-hCG.

Common causes

Pregnancy
PCOS
Hyperprolactinaemia
Hypothalamic amenorrhoea: stress, weight loss, excessive exercise, eating disorder
Thyroid disease
Premature ovarian insufficiency
Uterine adhesions, Asherman syndrome
Drugs: antipsychotics, opioids, hormonal contraception

Investigation sequence

Pregnancy test
TSH and serum prolactin
FSH, LH, estradiol if ovarian failure suspected
Androgen profile if hirsutism/virilisation
Pelvic USG
MRI pituitary if persistently elevated prolactin or neurological symptoms

Treatment principles

Treat cause:

PCOS: weight management, cycle protection with COC or cyclic progestogen if not seeking pregnancy
Hyperprolactinaemia: dopamine agonist after excluding drug cause/pituitary lesion
Hypothyroidism: thyroxine
Hypothalamic cause: nutrition, reduce exercise/stress, address eating disorder
Premature ovarian insufficiency: hormone replacement unless contraindicated, bone-health counselling
Asherman syndrome: hysteroscopic adhesiolysis

3. Dysmenorrhoea

Definition

Painful menstruation, usually crampy lower abdominal pain occurring just before or with menses.

Primary dysmenorrhoea

No pelvic pathology
Starts within 6-12 months after menarche, once ovulatory cycles begin
Due to excess endometrial prostaglandins causing uterine hypercontractility and ischemia
Pain begins just before/on day 1 of menses and lasts 1-3 days
Examination is normal

Secondary dysmenorrhoea

Due to pelvic pathology
Begins later, may progressively worsen; pain may occur before and continue after menses
Causes: endometriosis, adenomyosis, fibroid, PID, ovarian cyst, cervical stenosis, IUCD-related pain

Management

Primary dysmenorrhoea

Reassurance, exercise, heat
NSAIDs, started at onset or 1-2 days before expected menses
Combined hormonal contraception if NSAIDs inadequate or contraception desired
Persistent/refractory symptoms: assess for secondary cause, especially endometriosis

Exam pearl: A young patient with severe dysmenorrhoea not responding to NSAIDs/COC should be evaluated for endometriosis.

4. Premenstrual syndrome and PMDD

PMS

Cyclical physical, psychological, and behavioural symptoms in the luteal phase that resolve after menstruation begins.

Symptoms: irritability, mood swings, breast tenderness, bloating, headache, fatigue, food craving.

PMDD

A severe form with marked affective symptoms and functional impairment.

Diagnosis

Symptom diary for at least 2 cycles
Symptoms occur in luteal phase and remit shortly after menstruation begins.

Management

Lifestyle: exercise, sleep, reduce stress
CBT
COC, especially selected regimens
SSRI for severe PMS/PMDD
Refer when severe mood symptoms or suicidal thoughts occur

5. Abnormal uterine bleeding (AUB)

Definition

Bleeding from the uterine corpus that is abnormal in regularity, frequency, duration, or volume in a non-pregnant woman.

First rule

Exclude pregnancy-related causes first: miscarriage, ectopic pregnancy, gestational trophoblastic disease.

FIGO PALM-COEIN classification

Structural causes: PALM

P - Polyp
A - Adenomyosis
L - Leiomyoma/fibroid
M - Malignancy and hyperplasia

Non-structural causes: COEIN

C - Coagulopathy
O - Ovulatory dysfunction
E - Endometrial
I - Iatrogenic
N - Not yet classified

The PALM-COEIN classification remains the standard framework for AUB assessment. ACOG AUB guidance

Important clinical terms

Heavy menstrual bleeding (HMB): excessive menstrual blood loss that affects physical, emotional, social, or quality-of-life functioning.
Intermenstrual bleeding: bleeding between expected periods.
Postcoital bleeding: bleeding after intercourse. Think cervical pathology.
Postmenopausal bleeding: endometrial cancer must be excluded.

AUB: clinical assessment

History

LMP, cycle pattern, duration and amount of bleeding
Pregnancy possibility
Drugs: anticoagulants, hormones
Symptoms of anaemia
PCOS/thyroid symptoms
Bleeding disorder history: easy bruising, epistaxis, heavy bleeding since menarche
Cancer risk: obesity, chronic anovulation, diabetes, tamoxifen, family history

Examination

Assess haemodynamic status if acute heavy bleeding
Pallor, BMI, hirsutism, thyroid signs
Abdominal mass
Speculum examination: vaginal/cervical lesions, bleeding source
Bimanual examination: uterine size, fibroids, adnexal mass

Investigations

Urine pregnancy test
CBC, ferritin if heavy/prolonged bleeding
TSH only if clinically indicated
Coagulation testing if bleeding disorder suspected
Pelvic USG: first-line imaging for structural lesion
Endometrial biopsy if:
- Age 45 years or more with AUB
- Younger patient with persistent AUB plus risk factors for endometrial hyperplasia/cancer
- Failed medical treatment or persistent bleeding

Acute AUB: management

If haemodynamically unstable

ABC resuscitation
Two wide-bore IV lines, blood grouping/cross-match
CBC/coagulation profile, fluids, blood products as needed
Urgent senior gynaecology review
Medical control of bleeding if appropriate, or uterine evacuation/tamponade/surgical intervention depending on cause and stability

If stable

Medical options depend on cause, contraindications, and fertility wishes:

Tranexamic acid
NSAID
Combined oral contraceptive
Oral progestogen
LNG-IUS for long-term heavy bleeding where suitable

Definitive surgery: hysteroscopic polypectomy/myomectomy, endometrial ablation in selected women who have completed childbearing, or hysterectomy when appropriate.

6. Postmenopausal bleeding (PMB)

Definition

Any vaginal bleeding occurring after 12 months of amenorrhoea due to menopause.

Rule

Endometrial carcinoma must be excluded until proven otherwise.

Causes

Atrophic endometrium/vaginitis, most common
Endometrial polyp
Endometrial hyperplasia/carcinoma
Cervical malignancy
Hormone therapy
Trauma/infection

Evaluation

Speculum examination
Transvaginal USG for endometrial thickness
Endometrial biopsy/hysteroscopy when indicated
Cervical screening status and cervical assessment

Exam line: “Postmenopausal bleeding is carcinoma of endometrium until proved otherwise.”

7. Menopause

Definition

Permanent cessation of menstruation due to ovarian follicular depletion, diagnosed retrospectively after 12 months of amenorrhoea without another cause.

Hormonal changes

Low estrogen and inhibin
High FSH and LH

Symptoms

Vasomotor: hot flushes, night sweats, palpitations
Genitourinary syndrome of menopause: vaginal dryness, dyspareunia, urinary urgency/recurrent UTI
Psychological: poor sleep, mood change
Long term: osteoporosis, fracture risk, cardiovascular risk

Management

Lifestyle: exercise, smoking cessation, calcium/vitamin D adequacy
Vaginal moisturisers/lubricants for mild urogenital symptoms
Local vaginal estrogen for genitourinary symptoms when suitable
Menopausal hormone therapy for troublesome vasomotor symptoms after individual risk assessment
- Uterus present: estrogen plus progestogen
- No uterus: estrogen alone

Important cautions for systemic hormone therapy

Avoid or seek specialist opinion with breast/endometrial cancer, unexplained vaginal bleeding, active/past thromboembolism, stroke, or active liver disease.

One-minute recall

Amenorrhoea: pregnancy first.
Primary amenorrhoea: assess breasts, uterus, then FSH.
Dysmenorrhoea: primary = prostaglandin-mediated; refractory pain = consider endometriosis.
AUB: pregnancy test → stabilize if heavy → PALM-COEIN → USG ± biopsy.
AUB biopsy: ≥45 years, or younger with risk factors/persistent bleeding.
PMB: exclude endometrial cancer.
Menopause: 12 months amenorrhoea; uterus present means estrogen needs endometrial protection with progestogen.

Recent systematic-review evidence continues to support FIGO-based structured classification for AUB, although it does not alter the above exam framework. PMID: 39234899.
