She is not sexually active. Sexual development is Tanner stage 3. Examination shows no abnormalities. Which of the following is the most appropriate next step in management?

C

  #2

but she's not sexually active

  #6

Her menses have occured every OTHER month....something's up here. I'd measure LH and FSH levels...

Doesn't make much sense to talk about pregnancy prevention in this case? What's everyone's reasonsing for chosing that answer?

  #8

if she is menstruating every other month...that means her cycles last 60 days...that's not normal. she isn't sexually active, don't need to worry abt preg prevention right now. worry abt the abnormal menstrual cycle first...B

  #9

A)
Menstrual cycles are usually irregular in the first year to two after menarche, so no need to investigate further.

  #10

and she is NOT SEXUALLY ACTIVE YET! It's better for her to be aware!

  #11

SO WHATS THE ANSWER FINALLY..

I think its A..coz early cycles tend to be irregular so not B.




  #12

I THINK ITS B SHE IS OLIGOMENNORHOEIC NEEDS EVALUATION OF FSH LH

  #13

A

I think A too. Menses are irregular initially. So dr_jojo, what's the answer?


  #15

A is the correct answer.
There is a clear rule that the two first and the two last years of menstruation are expected and allowed to be irregular. B is jumping the gun, considering this rule of thumb.
About 20% of the American population gets pregnant during their teens (the highest rate among Western countries), pregnancy consulting is of utmost importance in this girl.
The girl is lagging a bit behind in her breast development (with her age, she should be at Tanner 4), but 2.5 SD´s is 2 years with Tanner stages and is allowed in terms of variability, thus no reason to jump into hormone testing.

  #16

There is no reason to talk to this 13 year old about pregnancy..i don't think it's within reason. The child came in for a check-up. Leave that issue to the parents, me thinks. What pediatric/medicine books has anyone read that recommends giving a pregancy prevention talk to young teens when they come in for check-up????

@all those who think not to discuus preg prevention with a 13 yr old non sexually active girl...ppl, this is US she is living in!

That's kinda derogatory don't you think? I live in the US.. it's wrong to assume this 13 yo girl needs the sex talk just because "it's the US she is living in". A check-up is no place for a pregnancy prevention talk by a Doctor. I still think that's the parent's job. Especially since she's not even sexually active.

In USA the average age girls start sexual activity is 15, isn't that true? It's the country with one of the worst (or the worst) statistics in teenager's pregnancy. I think that talk is appropriate at 13. Besides, no need to go after a hormonal problem during the first year after menarch with irregular cycles.

About being a parent-child issue, remember: doctors here counsel about contraception with minors with or without parental consent/knowledge. I think this conversation should happen away from the parents, by the way. That way the doctor would reeaaally know what's going on. It's the doctor's duty. I don't see it as a moral issue.

Irregular cucles t the 1st year of menarche is totally comman & requires no intenvention, but if extends, FSH, & LH values are the next step..

the only thing that some recommend is a blood profile if her bleeding is severe to detect anemia & supply Fe accordingly

The ans is A



  #21

Nice discussion I will go with A as well.
