B. Craniopharyngioma
C. Encephalitis
D. Hypothalamic hamartoma
E. McCune–Albright syndrome

6. A ﬁve-year-old girl presents with a history of accelerated growth, thelarche, pubarche and menarche. Examination revealed light to dark brown spots, predominantly noticeable on one side of the body without crossing the midline. What is your differential diagnosis?

A. Central precocious puberty
B. Cushing syndrome
C. Exogenous oestrogen exposure
D. Iatrogenic excessive use of cortisol treatment
E. McCune–Albright syndrome

7. A 7 year old girl was brought to the GP with complaints of pubic and axillary hair growth. She is otherwise asymptomatic with no history of vaginal bleeding. On examination, pubic hair was sparse.

A. Cushing syndrome
B. Central precocious puberty
C. Pseudopuberty
D. Physiological premature adrenarche
E. Congenital adrenal hyperplasia

8. A 6+ years old child has been brought to the GP with advanced growth spurt with thelarche and adrenarche of Tanner classiﬁcation stage 4 and with regular uterine bleeding for the last ﬁve months. Her bone age report showed she is two years more advanced than her chronological age. A pelvic ultrasound showed a pear-shaped uterus and with a 5 mm endometrial thickening and normal ovaries. She was otherwise asymptomatic with no signs of any significant medical illnesses. What is the probable diagnosis?

A. McCune–Albright syndrome
B. Central precocious puberty (CPP)
C. Estrogen-secreting ovarian tumours
D. Chronic Hypothyroidism
E. Pseudopuberty

9. A 7 old girl is brought to the GP clinic because she has been having regular monthly bleeds for the last four months. You suspect gonadotropin-dependent precocious puberty. What is the gold standard to conﬁrm your diagnosis?

A. Accelerated growth velocity of more than 6 cm/year
B. Advanced bone age
C. A pear-shaped uterine length >35 mm with an endometrial line
D. FSH response after GnRH stimulation test
E. Luteinizing hormone (LH) peak after gonadotropin-releasing hormone (GnRH) stimulation

10. A mother brings her ﬁve-year-old girl to the clinic. She noticed early excess pubic and body hair with clitoromegaly. She also noticed that her girl is taller than her peers. You suspect a mild non- classical form of CAH. What is the most sensitive investigation to diagnose mild forms of CAH?

A. Adrenocorticotrophic hormone (ACTH)-stimulation test
B. 17-hydroxy progesterone (17-OHPG)
C. Free Testosterone
D. Androstenedione
E. DHEAS

B. Physiological Stress
C. Repeated nipple stimulation
D. Acute renal failure
E. Pregnancy

12. Regarding Bromocriptine, which of the statements is false:
