Sexual Characteristics

Precocious puberty is defined as the onset of secondary sexual characteristics before 8 years of age in girls and 9 years in boys. Central Precocious Puberty (CPP) is caused by early activation of the hypothalamic-pituitary-gonadal axis. Laboratory test of LH, FSH, and Estradiol is recommended for monitoring suppressive effects from GnRHa therapy in the early three months and every six months. This study aimed to report a case of CPP in a 3-year and 3-month-old girl. A 3-year and 3-month-old girl went to the hospital with vaginal bleeding (menstruation), breast development, and pubic and axilla hair for 7-month-old. Physical examination found moderately ill with obesity, body weight 20 kg, height 98 cm. Tanner stage was A2M3P2, café au lait was found in the left forehead with size 7x3.5 cm. In March 2015 before GnRHa therapy, LH, FSH and Estradiol level increased with levels of 4.32 mlU/mL, 6.01 mlU/mL, and 67 pg/mL, and after 3 months of the treatment was 0.87 mlU/mL, 2.51 mlU/mL and <20 pg/mL. Pelvic ultrasonography showed suggestive precocious puberty, bone age 5-year and 9-month (Greulich and Pyle), CT-Scan of the brain showed hypothalamic tumor suspected hypothalamic hamartoma. This patient was treated with a GnRHa injection every 4 weeks. Leuprorelin is a synthetic non-peptide analogue of natural GnRH. The diagnosis was based on medical history, physical examination, laboratory, and radiological findings. The prognosis of the patient was good.

We describe the case of a 6.5-year-old girl with central precocious puberty (CPP), which signifies the onset of secondary sexual characteristics before the age of eight in females and the age of nine in males as a result of stimulation of the hypothalamic-pituitary-gonadal axis. Her case is likely related to her adoption, as children who are adopted internationally have much higher rates of CPP. She had left breast development at Tanner Stage 2, adult body odor, and mildly advanced bone age. In order to halt puberty and maximize adult height, she was prescribed a gonadotropin releasing hormone analog, the first line treatment for CPP. She was administered Lupron (leuprolide acetate) Depot-Ped (3 months) intramuscularly. After her second injection, she developed swelling and muscle pain at the injection site on her right thigh. She also reported an impaired ability to walk. She was diagnosed with muscle fibrosis. This is the first reported case of muscle fibrosis resulting from Lupron injection.

The Central Nervous System

Central precocious puberty (CPP) is due to the premature activation of the hypothalamic–pituitary–gonadal axis, which is responsible for the appearance of secondary sexual characteristics. It occurs before the age of 8 and 9 in girls and boys, respectively. CPP shows higher incidence in females than in males. Causes of CPP are similar in both sexes, but the idiopathic form is more frequent in girls, while organic forms are more frequent in males. Recent studies demonstrated a role of some genetic variants in the pathogenesis of CPP. The diagnostic evaluation based on accurate physical examination, assessment of the pituitary–gonadal axis, pelvic sonography in girls, and determination of bone age. Magnetic resonance of the central nervous system should be done in all boys and selected girls. Since the 1980s, pharmacologic treatment involves the use of gonadotropin-releasing hormone (GnRH) analogs. These drugs are characterized by few side effects and long-term safety. Many data are available on the outcome of GnRH analog treated female patients, while poor data are reported in boys. Adult height is improved in both sexes.

Minimal Information

<b><i>Background:</i></b> A random ultrasensitive luteinizing hormone (LH) (LH-ICMA) ≥0.3 mIU/L is highly accurate in confirming a diagnosis of central precocious puberty (CPP). However, a prepubertal value does not exclude the diagnosis. The clinical differences between patients with CPP who have a pubertal versus prepubertal LH-ICMA have not been clearly defined. Furthermore, there is minimal information regarding the utility of this test in boys with CPP. The objective of this study was to analyze differences between patients diagnosed with CPP who had a pubertal versus prepubertal LH-ICMA, including a cohort of boys. <b><i>Methods:</i></b> A retrospective chart review of children diagnosed with CPP within the last 10 years who had a baseline LH-ICMA obtained was performed. Variables analyzed included sex, age, ethnicity, bone age, BMI, etiology, Tanner stage (TS), testicular volume, and menarchal status. <b><i>Results:</i></b> Of 27 boys and 126 girls who qualified for the study, the LH-ICMA was pubertal in 87% and prepubertal in 13%. Girls with a pubertal LH-ICMA had higher baseline estradiol concentrations (<i>p</i> &#x3c; 0.001) and more advanced breast development (<i>p</i> = 0.015) compared to girls with a prepubertal LH-ICMA. Of girls with a prepubertal LH-ICMA, 74% had at least TS 3 breast development and 1 was post-menarchal. The LH-ICMA was pubertal in 96% of the boys with CPP in this study. <b><i>Conclusions:</i></b> The LH-ICMA can be prepubertal even in girls with advanced development. To our knowledge, ours is the largest cohort of boys in whom the accuracy of a random LH-ICMA has been reported.

AbstractObjectivesData on the predictive values of parameters included in the diagnostic work-up for precocious puberty (PP) remain limited. We detected the diagnostic value of basal sex hormone levels, pelvic ultrasound parameters and bone age assessment for activation of the hypothalamic-pituitary-gonadal axis in girls with PP, in order to help in the decision to perform GnRH testing.Patients and methodsWe retrospectively considered 177 girls with PP. According to puberty evolution, the girls were divided into two groups: rapid progressive central precocious puberty (RP-CPP) and non/slowly progressive/transient forms (SP-PP). In all patients we considered Tanner stage, basal luteinizing hormone (LH) and estradiol (E2) values, bone age, and pelvis examination. We assessed the diagnostic value of each variable and identified the number of pathological parameters that best identify patients with RP-CPP.ResultsBasal LH ≥ 0.2IU/L, E2 level ≥ 50 pmol/L, uterine longitudinal diameter ≥ 3.5 cm, transverse uterine diameter ≥ 1.5 cm, endometrial echo and ovarian volume ≥ 2 cm3 were significantly associated with RP-CPP (p ≤ 0.01). The ability to diagnose RP-CPP was enhanced with increasing number of pathological hormonal and instrumental parameters (p < 0.001). With more than three parameters detected, sensitivity and specificity reached 58% (95%CI 48–67) and 85% (95%CI 74–92), respectively, with a PPV = 86% (95%CI 76–93) and PPN = 54% (95%CI 43–54); the area under the ROC curve was 0.71 (95%CI 0.65–0.78).ConclusionDespite the availability of different tests, diagnosing RP-CPP remains difficult. A diagnosis model including at least three hormonal and/or ultrasound parameters may serve as a useful preliminary step in selecting patients who require GnRH testing for early detection of RC-PP.

Sexual Characteristics

Turner's syndrome is the most common karyotypic abnormality causing gonadal failure and primary amenorrhea. It is characterized by short stature and absence of secondary sexual characteristics. It is diagnosed by increased plasma FSH and LH level with low level of estrogen i.e. hypergonadotrophic hypogonadism. Ultrasound abdomen reveals streak ovaries and atrophic uterus. Karyotype confirms the diagnosis of Turner's syndrome (45XO). We present here a 15 years girl who presented with primary amenorrhea with short stature with breast development corresponds to Tanner stage I. Her FSH was raised. Ultrasound abdomen showed uterine agenesis and streak ovaries. Karyotype showed 45XO which confirmed the diagnosis of Turner's syndrome. She is now on estrogen therapy and her height has increased and breast development corresponds to Tanner stage II. Keywords: hypergonadotrophic hypogonadism, primary amenorrhea, Turner's syndrome

Precocious puberty is characterised by premature appearance of secondary sexual characteristics before the age of 7 years in girls and 9 years in boys. Dandy-Walker malformation comprises a spectrum of intracranial malformations of the posterior fossa. We present a case of a 7-year-old male child who has presented with features of central precocious puberty and on further evaluation has been found to have Dandy-Walker variant and secondary hypothyroidism. The following case report describes this association which is extremely rare and has never been described in literature.

• Puberty is defined as the acquisition of secondary sexual characteristics, with a view to reproductive capability. • Assessment of puberty can be done by Tanner stages or the puberty phases. • Timing of pubertal onset and sequence of changes is carefully controlled. • Premature sexual maturation: ◦ <8 years in girls; menarche <11 years ◦ <9 years in boys. • Central precocious puberty or gonadotropin-dependent precocious puberty: ◦ hormone secretion is similar to normal puberty ◦ may be idiopathic, genetic, or secondary to central nervous system/pituitary tumour or insult ◦ treatment is with gonadotropin-releasing hormone analogues. • Gonadotropin-independent precocious puberty (independent source of sex steroid, e.g. gonadal tumour): ◦ treatment should address the primary cause. • Late puberty: ◦ pubertal events within the later normal range. • Delayed onset of puberty: ◦ absence of secondary sexual characteristics: ■ >13 years in a girl ■ >14 years in a boy • Central causes (low follicle-stimulating hormone (FSH)/luteinizing hormone (LH)): ◦ chronic illness ◦ eating disorders ◦ physiological ◦ hypogonadotropic hypogonadism. • Peripheral causes (high FSH/LH): ◦ gonadal dysgenesis including chromosomal syndromes, e.g. Turner, Klinefelter ◦ gonadal damage including cancer treatments. • Treatment: ◦ low-dose sex hormone to induce growth and secondary sexual characteristics ◦ recombinant FSH/LH to induce fertility potential.

Myopic Progression

We sought to determine whether the myopic progression of patients with central precocious puberty (CPP) who were undergoing treatment differed from that of their healthy peers with normal pubertal onset and progression. Eighteen girls with CPP and 14 age-matched controls who underwent regular ophthalmic examinations for at least 1 year were included. All the CPP patients received a 3.75 mg leuprolide acetate depot subcutaneously every 28 days. The spherical equivalent (SE) and axial length (AL) for myopia progression and the pubertal parameters (height, body weight, body mass index, Tanner stage, and bone age) were compared between the two groups. Of 32 subjects with a mean age of 8.6 ± 0.7 years, the SEs and ALs did not differ at baseline between the two groups, which had similar weight and similar body mass index. After 1 year, both the CPP patients and controls showed myopic progression, with an average myopic shift of −0.73 ± 0.48 diopters (D) and AL elongation with a mean change of 0.44 ± 0.61 mm. The SE and AL changes over 1 year were greater in the controls than those in the CPP patients, which was not statistically significant (–0.85 ± 0.55 D vs. –0.64 ± 0.41 D and 0.55 ± 0.89 mm vs. 0.35 ± 0.22 mm, respectively). The change in AL correlated significantly with the change in the height (β = 0.691, p = 0.039). In this 1-year study, the CPP patients with treatments trended to show less myopic progression than the controls.

Hair Development

The parents of a 04-year-old girl bring her to a Gynaecologist because of breast development, appearance of pubic hair and periodic per vaginal bleeding. Her medical history is unremarkable. The parents are of average height, and the mother reports first menstruating when she was 11 years old. At physical examination, the girl is 100 cm tall , weighs 17 kg, and has a bodymass index of 17. Her pubertal development is classified as Tanner stage 3 breast development and Tanner stage 2 pubic hair development. She was diagnosed as a case of precocious puberity. Appearance of secondary sexual development before the age of 9 in a male child and before the age of 8 in a female child is called precocious puberty. When the cause of precocious puberty is premature activation of the hypothalamic-pituitary axis, it is called central or complete precocious puberty and she was a case of central precocious puberty. After proper consult she was treated by GnRHa suppressor of pituitary till 11 years of age.Bangladesh J Obstet Gynaecol, 2015; Vol. 30(2) : 109-112
