Control of normal menstruation

(I) Vascular Theory: Degeneration of corpus luteum - - Oestrogen & progesterone - - Stromal Oedema Shrinkage of endometrium ++ Coiling of spiral arteriols Ischaemia & necrosis of  superficial & middle layer of endometrium.

(II) Prostaglandin Theory: PG F2a V.C:& Myometrial contraction Thromboxane V.C. & aggregation of platelets

PG E V.D. 2 Prostacycline V.D. & - - aggregation of platelets

Lysosomal theory

(III) Lysosomal Theory:

Phospholipids

Oestrogen

Phospholipase A2

Phospholipase A2

Progesterone

Tissue regeneration theory

(IV) Tissue Regeneration Theory: Regeneration of endomerium starts within 48h of flow.

(V) Relaxin Theory: Relaxin causes hypertrophy of endothelium of basal & spiral arterioles - - blood loss.

(VI) Haemostatic Theory: + + Fibrinolotic Activity of endometrium

Diagnosisof abnormal uterine bleeding

Diagnosis of Abnormal Uterine Bleeding (I) History: Personal: age, marrital state, parity.

Present: amount, character, duration, associated symptoms, UT or GIT symp., emotional.

Menstrual: periods of amenorrhea

Past: Medical, hormonal, surgical.

Obstetric: DUB in purperium, choriocarcinoma.

Family: Endometrial carcinoma

(II) Examionation General: anaemia, cachexia, chest & Ht., bl. press., thyroid.  Abdominal: pelviabdominal mass, pregnancy, ascitis.

(III) Investigations 1. D&C biopsy biopsy: 2. Hematological: -Hb%

- Bl. Cl. time

- Tournique T.

3. Vaginal smear : 4. Endocrinal:

Local:

Thyroid and adrenal

5. Hysteroscopy: polyp polyp, malformations, myomas, remnants of conception, endometrial C. 6. Laparoscopy: ov.&tubal mass, endometriosis, PID, ectopic. 7. U/S: pelvic pelvic mass.

Treatment of abnormal uterine bleeding

Treatment of Abnormal Uterine Bleeding General General

Medical

- Anaemia - Bl. transf .

1. NSAD: • e.g. Ibuprofen (200-400 mg), Naproxen (250 mg), mefenamic acid (250-500 mg). t.d.s during bleeding only.

Cause Cause

• nausea, vomiting, diarrhea.

- Hypertension

2. Antifibrinolytic Agents:

- Bl.diseases.

Tranexamic acid (cyclokapron), 1gm/4h for 3 days then - - (22 gm /period).

- Thyroid dis. - Polypectomy myomectomy.

3. Ethamsylate (Dicynone): • - - capillary fragility, has anti-PG & antihyaluronidase effect. • 500 mg/6h starting 5 d before menses for 10 d.

Hormonal treatment

Hormonal Hormonal 1.Oral contraceptives: • Hypoplasia & anti-PG in endometrium. 1- 4 pills /d.. bleeding stopped ...1 pill (21 d). - Nausea & vomiting.

2. Progestogens: • Opposes action of estrogen on endometrium • Norethisterone (Primulot-N) or norethisterone acetate (Primulot-Nor) 2 x 5 mg/d. up to 30mg/d.

3. Danazol: • Isoxazole derivative of 17 - ethinyltestosterone . 400 mg/d. • Atrophy of endometrium systematically by - - Gn secretion & ov. steroidogenesis, locally - - E & progesterone receptors . • Expensive & side effects e.g. acne, weight gain and hirsutism.

4. LHRH analogues: • Inhibit Gn secretion from pituitary. 200 - 400 microgram nasal spray / d. Quite expensive

Surgical treatment

Surgical Surgical (I) Conservative Surgery: Endometrial ablation or resection using diathermy, thermal (ballon, microwave ..etc.) or laser. N.B. Uterine curettage has a good diagnostic but short-term therapeutic value.

(II) Hysterectomy: 1. Failure of previous lines of treatment. 2. Associated pelvic lesions as fibroidor malignancy. 3. Peri- and post menopausal bleeding usually treated by hysterectomy.
