(axillary hair)

Abdomen - suprapubic mass

Pelvis       - external genitalia, tanner staging, speculum - imperforated hymen 

              Atrophic vaginalais/ uterus, adnexeal masses / tenderness / pregnancy test if sexually active

INVESTIGATIONS

PRIMARY                                    SECONDARY       
                                                 

FSH/LH/Prolactin/Estradiol          FBE,BSL,U & E, BSL

Chromosomal analysis                      FSH,LH,Estradiol,Prolactin,TFT

Pelvic USS/ Vag/ PT                          Pelvic USS

TFT, FBE                                              Bone density

                                                                    CT/MRI – Pituitary tumor

MANAGEMENT 

physiological/ constitutional/ familial

• 1st period usually occurs after 2 years of breast development, individual variation presents
• referral to gynecologist
• hormonal challenge test if needed
• (hand book) review with investigations --- no periods after 1 years --- repeat estradiol

excessive exercise

• investigate to exclude other causes
• advise on exercise, referral to dietician, gynaecologist
• (Ca, Vit D, OCP/HRT to prevent osteoporosis)

Asherman's syndrome

• investigation - pregnancy test, hormones, USS
• explain the procedure - curettage --- complications --- formation of adhesion/ scars/ bands
• referral to gynecologist

            - hysteroscopy - small flexible optic tube is inserted through the cervix to see the uterine

                                       cavity ---intrauterine adhesion --- cut 

            - contrast X Ray study - to define the scar tissues & uterine structure

            - Estrogen - to repair the lining 

            - complications of hysteroscopy - uncommon, anesthetic risk, infection, bleeding, pain

            - effectiveness depends on the extent of the disease

Post pill amenorrhea (HAND BOOK)

• Gradual reduction of periods - ASK!!!
• The pill causes thinning of the womb lining (female hormone - progesterone)
• Investigate to exclude other causes
• this is reversible once the pill is stopped
• either continue with OCP if no concerns or change to other forms or micrognon 50/ Triphasic pills
• referral to specialist if necessary
