A) Gonadal Dysgenesis (Turner syndrome) 45,X0 (missing x on 23 par)
Short stature ,ovarian insufficiency
Instead of developing ovaries they have streak gonads.
**Fsh levels elevated because of ** no feedback inhibition from estrogen to the pituitary.
Treatment: Estrogen and progesterone replacement.
B)Hypothalamic –Pituitary Failure :Kallman Syndrome: Inability of Hypothalamus to produce Gnrh and also anosmia because the defect is close to olfactory area.
FSH levels are low
Treatment: Estrogen and progesterone replacement for secondary sexual characteristics. *(also known as hypothalamic hypogonadism, familial hypogonadism with anosmia, or hypogonadotropic hypogonadism)
kallman = inherited condition, meaning it ispassed on from parents to their children. Mothers can passon the gene to their daughters and sons, but fathers can usually only pass it onto their daughters. The condition is five times more common in boys (one boy in every 10,000) than in girls.
Secondary amenorrhea:
3 main causes:
Secondary amenorreah managment ?
1.First Step is to rule out Pregnancy through **Beta Hcg **.
Next step:??
2.Thyrotropin TSH:Hypothyroidism can lead to amenorrhea by elevating TRH that in turns elevates prolactin.Treatment:Thyroid replacement
3.Prolactin Level:Elevated prolactin level leads to amenorrhea through Gnrh.
- Medications:Anti psychotics and anti depressants have anti dopamine effect.
- Tumor: Pituitary Tumor and idiopathic.
- Hint:Dopamineand prolactin are inversely related
4 .** Progesterone Challenge** Test: PCT:
Administer a single dose of I/M progesterone or 7 days of oral medroxy-progesterone acetate.(MPA)
-Positive PCT: Withdrawl bleeding is diagnostic of anovulation.
-Negative PCT:reasons may be inadequate Estrogen or outflow tract obstruction.
5. Estrogen-Progesterone Challenge test: EPCT: **
- 21 days of oral estrogen followed by 7 days of MPA> Positive EPCT:
- Withdrawal bleed positive means inadequate estrogen.
- Etiology ?
- FSH?
- ●Low** FSH = CNS Pathology
- ●High FSH = Ovarian Failure .There can be two causes of Premature Ovarian failure:
- 1. X Chromosome Mosaicism:Premature ovarian failure (POF, OMIM 311360) is defined as the cessation of ovarian function before the age of 40, associated with elevated gonadotropins serum levels **(FSH ≥ 40 UI/l) **and affects at least 1%–3% of women of reproductive age,X chromosome can have multiple kind of defects during ageing in these people like deletions,tranlocations etc…
2.Savage Syndrome:
-1.Ovaries have follicles are present but don’t response to GNRH impulses
-2.Resistant ovary syndrome isone of the disease lead to ovarian failure and secondary amenorrhea. Diagnosis of this disease is based on having a normal 46, XX karyotype, normal secondary sexual characteristics, elevated follicle-stimulating and luteinizing hormone, and normal anti-Müllerian hormone.
————
Negative EPCT:
Absence of withdrawl bleeding
Cause could be outflow tract obstruction
-Asherman Syndrome: Result of extensive Curettage and infection induces Adhesions.
Next Step? Hysterosalpingogram.
Treatment:Hysterscopic adhenolysis followed by estrogen stimulation an inflatable stent is then placed to prevent readhesions**
HEAVY MENSTRUAL BLEEDING
AND
DYSMENO
HMB causes:
- most common sigle cause is DYSFUNCTIONAL UTERINE BLEEDING ( DUB)
- 2 types :
HMB causes:
DUB investigations
uterine causes:
HMB causes:
systemic causes:
HMB causes:
HMB TREATMENT :
- non hormonal (nsaids or tranexamic acid)
- hormonal (levonnogestrel mirena)
emergency menorrhagia
Uterine fibroids (leiomyoma):
Fibroids are benign tumours of smooth muscle of the myometrium. They are classified according to their location: subserosal, intramural, subendometrial or intra-uterine. They are oestrogen-dependent and shrink with the onset of menopause.
CLINICAL FEATURES:
Lifetime incidence of 60–70% in Caucasian women
Only 1 in 800 develop malignancy
Usually asymptomatic
SYMPTOMS:
Often asymptomatic if small
Menorrhagia
Dysmenorrhoea
Pelvic discomfort ±pain (pressure) including dyspareunia
Bladder dysfunction
Pain with torsion of pedunculatedfibroid
Pain with ‘red degeneration’—only in pregnancy (pain, fever, local tenderness)
Infertility (acts like IUCD if submucosal)
Calcification
MANAGEMENT:
Medical management the same as for DUB :
-Levonorgestrel IUD has now largely taken over as the Preferred option for reduction of bleeding.
-GnRH analogues—especially if >42 years can shrink fibroids (maximum 6 months)—use only immediately pre-operative
●Surgical options:
–myomectomy (remove fibroids only, esp. child-bearing years)
–hysteroscopic resection/endometrial ablation
–hysterectomy
●Other option: uterine embolisation
Premenstrual Syndrome:
Premenstrual syndrome (PMS) is defined as a disorder of non-specific somatic, psychological or behavioral symptoms occurring during the late luteal phase of the menstrual cycle.The symptoms of PMS decrease in severity just before and during menstruation. Premenstrual Syndrome:
The most common psychological symptoms are depression and irritability, while headache, bloating and breast tenderness are the most common physical symptoms.
CLASSIFICATION:
It is convenient to classify PMS in terms of severity of symptoms.
●Mild:symptoms signal onset of menstruation. No medical advice sought or needed.
●Moderate:symptoms annoying but insufficient to interfere with function at home or work. Medical advice sought in about one-third.
●Severe:symptoms are such that functions at work or home are disrupted. Medical advice is usually sought. This disruptive form is labelled **PMDD **
Diagnosis:
Thorough history—including diet, exercise habits, psychosocial background, emotional influences and family history
Menstrual calendar—for 3 months, showing timing of the three main symptoms
Physical examination to exclude gynecological, endocrine or other systemic disease; and also include:–breast examination (if breast tenderness)–cervical screening test
Investigations (to exclude other causes):
●–thyroid function tests
●–full blood count
●–electrolytes and creatinine
●–FSH and oestradiol—if perimenopause suspected
●–serum androgens—if oligomenorrhoea present
**MANAGEMENT **
**Explanation, reassurance and insight
**Cognitive-based therapy , which has been shown to have a positive effect in several RCTs,is very Helpful.
●Keeping a diary
●Advise the patient to keep a daily diary of all her symptoms and when they occur over a 2–3 month period. This information should help her to plan around her symptoms: for example, avoid too many social events and demanding business appointments at the time when PMS symptoms are worst.
Dietary advice
1:Advise the patient to eat regularly and sensibly; eat small, frequent meals and aim for ideal weight.Increase amount of low-GI complex carbohydrates, leafy green vegetables and legumes.
Decrease or avoid: refined sugar, salt, alcohol, caffeine (tea, coffee, chocolate), tobacco, red meat and excessive fluid intake during premenstrual phase.
Decrease total protein to 1 g/kg/day; decrease fats.
Exercise
Recommend a program of regular exercise such as swimming, aerobics, jogging or tennis. Such exercise has been proven to decrease depression, anxiety and fluid retention premenstrually
Relaxation
Advise patients to plan activities that they find relaxing and enjoyable at the appropriate time. Consider stress reduction therapy, including meditation, yoga, relaxation techniques and appropriate counselling.Appropriate dress:loosedressing
●Medication:
●Pharmaceutical agents that have been used with success in some patients and little or no relief in others include diuretics (e.g. spironolactone), vitamins and minerals (e.g. pyridoxine and evening primrose oil), simple anti-inflammatories (e.g. aspirin, mefenamic acid) and hormonal preparations such as the **OCP. A combination of agents may have to be used.
SUPPLEMENTS:Women often enquire about the use of vitamins, minerals and herbal remedies for PMS. The evidence base for symptom relief so far is as follows:
pyridoxine/vitamin B6 up to 100 mg daily (evidence limited, beware nerve damage to hands/feet with higher doses)elemental calcium, 1200 mg to 1500 mg daily (two randomisedcontrolled trials have shown significant benefit)elemental magnesium** up to 400 mg daily (minimal evidence)evening primrose oil 500 mg daily (no benefit over placebo)Agnuscastus(Premular®) is an extract of the berries from the chaste tree (several small randomisedcontrolled trials have indicated some benefit over placebo)
ORAL CONTRACEPTION:It is appropriate to use a COC-containing ethinyloestradiol and drospirenone since a meta-analysis of drospirenone, which is a progestogenderivative of spironolactone, concluded that it was effective in reducing the severe symptoms of PMDD.
Moderate to severe PMDD:fluoxetine20 mg (o) or sertraline50 mg (o) daily in morning for 14 days before anticipated onset of menstruation and through to the first full day of menses of each cycle
Atrophic vaginitis:
In the absence of oestrogen stimulation, the vaginal and vulval tissues begin to shrink and become thin and dry in old age in post menopausal women. This renders the vagina more susceptible to bacterial attack because of the loss of vaginal acidity. Rarely, a severe attack can occur with a very haemorrhagicvagina and heavy discharge:
●yellowish, non-offensive discharge
●tenderness and dyspareunia
●spotting or bleeding with coitus
●the vagina may be reddened with superficial haemorrhagicareas
TX
Oestrogen cream or pessary(e.g. Ovestin, Vagifem) daily at bedtime for 2–3 weeks, then once or twice weekly
●or
●zinc and castor oil soothing cream
●Note:perform a careful speculum examination.
