Precocious puberty refers to the appearance of signs of puberty at an earlier age than is considered normal. It occurs ten times more commonly in  girls than in boys. The overall incidence ranged from 1/5000 to 1/10,000 children. The cause is idiopathic in 90% of cases of female precocious  puberty. We present BA a 24 month old female toddler who presented with one year history of progressive breast development and 6 month history of pubic hair growth. There was associated increasing weight, height and vaginal secretion. There was no similar occurrence in the family. Mother attained menarche at 14 years of age. Essential finding at presentation revealed a toddler who is heavy and tall for age with a weight of 17kg (>95th percentile for age and sex), height of 90.5cm (90th percentile for age and sex), Occipito-frontal circumference of 49cm (normal). Her sexual maturityrating was Tanner stage 3 for breasts and stage 2 for pubic hair. An assessment of precocious puberty was made. Her investigation result showed an advanced bone age of 5 years; elevated serum gonadotrophins in the pubertal range; and essentially normal cranial CT. Abdomino-pelvic USS showed an enlarged uterus for age, and a dominant right follicle with internal echo measuring 17.1mm X 15.2mm. Parents were counseled on the need for treatment to arrest the progression of precocious puberty but yet to respond because of financial constraint after 2 years of diagnosis. Female precocious puberty is ten times more common than male precocious puberty. The aetiology is idiopathic in 90% of cases and It is amenable to treatment. Integration of the investigation and treatment of childhood endocrine disorders into the National Health Insurance scheme will be a great panacea to the challenge of prompt management in developing countries.

Isosexual precocious puberty in a girl child is defined as thelarche before 6 years in African–Americans and 7 years in Caucasians and menarche before the age of 9 years. In 1960, Van Wyk and Grumbach first described a syndrome characterised by breast development, uterine bleeding and multicystic ovaries in the presence of long standing primary hypothyroidism. We describe an interesting case of 8 year old girl presented with the complaint of abdominal mass with history of premature menarche and breast development. She is found to have gross hypothyroidism, hyperprolactinemia, prepubertal LH levels, multicystic ovaries and delayed bone age. Thyroid replacement amazingly settled her problems bringing her to normalcy.

Abstract Introduction: Familial Male-Limited Precocious Puberty (FMPP), also known as testotoxicosis, is a rare cause of precocious puberty in males. It is caused by a mutation in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene, resulting in the receptor to be constitutively activated. This results in precocious puberty in males with rapid skeletal maturation and compromised final adult height if not treated. A combination on anti-androgens and aromatase inhibitors are the mainstay of treatment. Case: A 16-month-old male presented to our clinic due to concerns of precocious puberty. Pubic hair was noted at 6 months of age along with rapid growth acceleration. There was no known exposure to testosterone and no family history of early puberty or subnormal adult height. Upon presentation, his height was over the 99th percentile while his target height is at the 50th percentile. Physical examination revealed prepubertal testes with pubic hair at Tanner stage II. A bone age was reported as 12-18 months at a chronologic age of 12 months. Initial lab evaluation revealed normal serum levels of 17 OHP, androstenedione and DHEA-S with a slightly elevated serum LH (0.7mIU/ml), and very elevated serum testosterone level (289ng/dl). Leuprolide and ACTH stimulation tests as well as MRI of the abdomen and pelvis were normal. Serum levels of AFP, β-hCG and IGF-1 were also normal. Bone age advanced to 6 years at a chronological age of 21 months and to 8 years by 26 months of age. At 26 months of age, his stretched penile length measured 11cm. LH receptor testing was obtained, which revealed a novel heterozygous missense mutation in the LHCGR gene (c.1733A>C; p.Asp.578Ala). The mutation was reported to be a variant of unknown significance though likely in the pathological end of the spectrum by variant analysis with SIFT and PolyPhen. He was started on treatment with anastrozole 1 mg daily and bicalutamide 25 mg daily at 2 and 9/12 years of age. Pubertal progression, linear growth and skeletal maturation slowed down with treatment. His bone age remained stable at 13 years from the age of 2 and 10/12 years to 4 years old. Pubertal stage and stretched penile length have also remained stable on treatment. He is tolerating treatment well. Conclusion: We report a novel mutation in the LHCGR gene causing FMPP in a 6-month-old male who is responding very well to a combination of bicalutamide and anastrazole with marked decrease in growth velocity, pubertal progression and skeletal advancement.

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.

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

Appearance of secondary sexual development before the age of nine in a male child and before the age of eight in a female child is called precocious puberty. Precocious puberty due to premature activation of the hypothalamic-pituitary axis is called central or complete precocious puberty. Incomplete precocious puberty is called if ectopic gonadotrophin secretion occurs in boys or autonomous sex steroid secretion occurs in either sex. Here we report a case of a 4-year-old girl brought to a gynecologist by her parents because of breast development, pubic hair and periodic per vaginal bleeding. Her medical history was unremarkable. The parents were of average height, and the mother reported first menstruation when she was 11 years. At physical examination, the girl was 100 cm tall, weighed 17 kg, and had a body mass index of 17. Her pubertal development is classified as Tanner stage 3 breast development and Tanner stage 2 pubic hair development.J Enam Med Col 2016; 6(3): 161-163

Abstract Background Toy slime is popular in Korea, and in parallel, pre-pubertal girls visit hospitals for early pubertal signs. Thus far, numerous studies have investigated the association of endocrine-disrupting chemicals (EDCs) with precocious puberty (PP). However, there is a lack of studies on the clinical manifestations and sex hormones. We aimed to investigate early pubertal development in Korean girls with or without a history of toy slime exposure and determine changes in bone age, Tanner stage, and sex hormones. Methods In this study, 140 girls underwent stimulation tests at Kyungpook National University Children’s Hospital Endocrinology Department, during January 2018 and December 2020. Patients were divided into two groups for gonadotropin-releasing hormone (GnRH) stimulation test and frequency of exposure to toy slime (EDCs). GnRH stimulation test was conducted after an intravenous injection of 100 µg of luteinizing hormone-releasing hormone. Slime exposure was defined as Slime ≥ 3 times/week for ≥ 3 months. Results History of slime exposure was found in 14 of 58 and 65 of 82 patients in the central PP (CPP) and non-CPP groups, respectively. Slime-exposed patients had advanced bone age, although their Tanner stage was low. Patients with a history of toy slime exposure were 5.5 times more likely to be diagnosed with non-CPP than patients without slime exposure (p < 0.05). Conclusions Exposure to toy slime in prepubertal girls may be associated with rapid clinical advancement of pubertal development and bone age, and the patients appear more likely to be diagnosed with non-CPP.

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.

This section of Pediatrics in Review reminds clinicians of those conditions that can present in a misleading fashion and require suspicion for early diagnosis. Emphasis has been placed on conditions in which early diagnosis is important and that the general pediatrician might be expected to encounter, at least once in a while. The reader is encouraged to write possible diagnoses for each case before turning to the discussion, which is on the following page. We invite readers to contribute case presentations and discussions. Case 1 Presentation A 17-year-old boy is admitted to the hospital for evaluation and management of recently diagnosed diabetes mellitus. His mother expresses concern about his acting-out behavior and about frequent difficulties in drinking from a glass due to tremors. On examination he is found to be 68.5 inches tall, and he has a mild scoliosis. Evaluation of sexual development reveals axillary hair at Tanner stage III, pubic hair at stage V, penile length of 8 cm, left testicular volume of 3.0 x 1.8 cm, and an undescended right testicle. No breast tissue is palpable. Case 2 Presentation A 16-year-old girl is seen at your office with a history of prolonged fatigue and weakness. She has missed school frequently over the past 4 to 5 months, having had many vague complaints of "no energy," headaches, sore throats, aching knees, and the feeling that she will almost "pass out" if she does gymnastics or physical exertion of any kind.
