  1. PUBERTY and MENARCHE Dr.EranthiSamarakoon

  2. PUBERTY • Is the time a girl becomes sexually mature and functionally able to reproduce . • The changes which occur at puberty are the development of secondary sexual characteristics and onset of menstruation • Puberty is the physical & mental development of the girl child to reach womanhood.

  3. PUBERTY • Begins around 09 years of age. • Includes the following aspects of physical development, • Formation of the breast buds which go on to complete development of the breasts. • Growth spurt. • Development of axillary & pubic hair. • Occurrence of menstrual periods. • Mental development from a child to an adolescent teenager & a woman. ( Interest in personal appearance, cosmetics, clothes & opposite sex.)

  4. TIME SCALE (YEARS) 9½ - 13 Breast buds appear 13 – 14 Growth of axillary & pubic hair 10 – 14 Growth spurt 11½ - 15 Developed feminine contours 13 – 16 Ovulation

  5. Menarche Menarche is the occurrence of the first menstrual period, known in our society as “attaining of age”. It is one aspect of the pubertal process. In Sri Lanka the normal age of menarche is between 9 to 15 years.

  6. The occurrence of puberty and menstruation require proper functioning of, • Hypothalamus • Pituitary • Ovary • Uterus • And the out flow tract

  7. SOME TRUE FACTS REGADING MENARCHE •  It is a natural occurrence & is only another mile stone in the girl’s life. • It should not be allowed to change the life style of the girl who should be allowed to blossom out in to a young woman gradually during the ‘teenage’ period. • There are no taboos associated with menarche or subsequent menstrual periods.

  8. Any type of food can be consumed. • Athletes, swimmers & dancers can continue training at menarche & during subsequent menstrual periods. • Social & cultural festivities should be kept to minimum & the child should be made to feel important and happy. • She should resume schooling in 2-3 days after menarche. • Bathing can be continued

  9. Pregnancy can occur at any time after menarche • Regular monthly periods may or may not occur soon after menarche

  10. Menstruation • Occur once in 25 – 32 days • Is not a cleansing or an excretory process of the body • It only indicates a cycle during which an ovum (egg) is released on the 14th day by the ovary and ends with the uterus shedding its endometrial lining (which becomes thick during the menstrual cycle due to the hormones) with the release of about 60ml of blood • It is not essential for life but indicates that ovulation has occurred ( an egg has been released) during the month

  11. Problems associated with puberty & adolescence • Primary amenorrhoea • precocious puberty • Irregular & excessive bleeding • Primary dysmenorrhoea • Vaginal discharge • Secondary amenorrhoea • Oligomenorrhoea

  12. Medical attention should be sought if menarche occurs before 09 years or does not occur till 16 years

  13. Irregular & excessive bleeding • Increased bleeding and short cycles are common in teenagers and is not due to an illness but due to lack of maturity of the hormones. • Immediate medical treatment is necessary to avoid anaemia • Abdominal examination, FBC and USS should be done • The diagnosis is dysfunctional uterine bleeding unless proved otherwise

  14. Treatment for Irregular & excessive bleeding • Combined oral contraceptive pills for 01 -03 cycles • Norethisterone 05mg b.d for 21 days (01-03 cycles) • Tranexemic acid and /or mefenemic acid is used only to reduce bleeding in regular menorrhagia • Oral iron therapy

  15. Primary dysmenorrhoea •  First day pain is normal • May be accompanied by vomiting and fainting • May start a few years after menarche • Cannot be cured but should be controlled with analgesics which should be commenced with the onset of the period before the pain begins • Paracetamol 500mg 06 hourly and/or mefenemic acid 500 mg 06 hourly are used

  16. Vaginal discharge • Increased vaginal discharge is normal • it does not require treatment, if not blood stained or associated with itching or burning. • It does not cause weight loss, abdominal pain or backache

  17. ABSENCE OF MENSTRUATION • Absence of menstruation for several months is common in teenagers. it is not due to an illness. • It occurs because ovulation is irregular in young girls. • Medical attention may be sought to relieve the anxiety of the parents. • The possibility of a pregnancy can not be ignored. • Attention should be paid if the child is overweight as it may be due to PCOS.

  18. Polycystic Ovarian Syndrome(PCOS)

  19. PCOS is a syndrome of ovarian dysfunction with the cardinal features of • Obesity • Hyperandrogenism • Polycystic ovarian morphology

  20. Diagnosis • Presence of two of the three following criteria is diagnostic of the condition. • Polycystic ovaries(either 12 or more peripheral follicles) or increased ovarian volume (greater than 10 cm). • Oligo or anovulation. • Clinical and/ or biochemical evidence of hyperandrogenism. • A raised luteinising hormone/follicle-stimulating hormone ratio is no longer a diagnostic criteria for PCOS owing to its inconsistency.

  21. Differential diagnosis • Diagnosis of PCOS require exclusion of • Hyperprolactinaemia • Androgen secreting ovarian or adrenal tumours • Cushing’s syndrome

  22. Clinical Features • Obesity • Oligomenorrhoea/amenorrhoea • Episodes of excessive bleeding after a period of amenorrhoea • Hirsutism • Subfertility • Recurrent miscarriage • Acanthosis nigricans

  23. Laboratory tests • Elevated testosterone. • Decreased sex hormone binding globulin. • Elevated LH. • Elevated LH : FSH ratio. • Increased fasting insulin. • Increased prolactin . • Increased oestrodiol , oestrone

  24. Ultra sound scan • The USS criteria for the diagnosis of PCOS are, • 8 or more subcapsular follicular cysts ~ 10mm in diameter • increased ovarian stroma. • Ovarian volume greater than 10 cm3.

  25. Treatment • There is no specific treatment for PCOS. • Treatment is directed at the symptoms.

  26. Exercise & weight control • Is the most important aspect of treatment. • Causes spontaneous resumption of ovulation • Improves fertility. • Increases sex hormone binding globulin levels. • Reduces insulin resistance. • Normalizes the glucose metabolism.

  27. Menstrual disturbances • Progesterone for the last 10 days of the cycle. • Cyclical treatment with progesterone. • Cyclical treatment with combined oral contraceptive pills.

  28. Role of Metformin • Improves obesity. • Increases ovulation rates. • Improves hirsutism. • Improves fertility.

  29. Hirsutism • Cyproterone acetate • Metformin • Cosmetic treatment

  30. Anovulation & Infertility • Weight reduction • Metformin • Ovulation induction - Clomiphene citrate - hCG injections • Ovarian drilling

  31. Long-term metabolic consequences • Diabetes mellitus • Dyslipidaemia • Hypertension • Cardiovascular disease • Endometrial carcinoma • Gestational diabetes mellitus

  32. NUTRITIONAL REQUIREMENTS OF THE ADOLESCENT • Adequate nutrition should be provided to the girl child for, • Growth • To restore the blood loss during menstruation • To prepare her to deliver a healthy baby without any complications during the pregnancy • The following dietary items are nutritious, cheap and readily available. Each meal should be rich in carbohydrates, protiens, vitamins and minerals

  33. Rice (carbohydrates) * dhall, greengram(mung), gram(kadala), cowpea, soya, eggs, sprats, fish, meat (proteins and minerals) – fish and meat should be added where economically possible. * Green vegetables, bananas and other fruits.
