The harmony of the organism development in different periods of ontogenesis, and especially puberty, determines the future fate of women in both medical and social aspects. The aim of the research was to study the total and partial body sizes in girls of pubertal period of ontogenesis. We surveyed 128 schoolgirls of 5-8 grades. We evaluated the stages of development of secondary sexual characteristics by hair growth in the axilla and pubis, the development of the mammary glands and age of onset of the first menstruation. According to G.G. Avtandilov’s classification, all girls were divided into three groups – prepubertal (preceding the appearance of pubic hair), pubertal (puberty before menarche) and postpubertal period (fixed and completed pubertal maturation). The group of pubertal girls consisted of 106 schoolgirls, who were divided into groups according to calendar age: 13-year-old (n=29), 12-year-old (n=30), 11-year-old (n=24) and 10-year-old (n=23). Anthropometric survey was conducted according to the scheme of V.V. Bunak and contained the definition of total (length and body weight) and partial (longitudinal, transverse and anterior-posterior) dimensions. The analysis of the obtained results was performed in the license package Statistica 5.5 using non-parametric methods of evaluation of indicators. In our study, it was found that anthropometric indicators characterize the physical development, the level of its harmony and morphofunctional maturity of girls within the pubertal period of ontogenesis. We found a progressive age dynamics of total and partial body size in girls of this age period. The periods of the most intensive growth within the pubertal period of ontogenesis of total and partial sizes of a body are established. At the end of puberty there is the most intense age increase in body length: a rapid increase in body weight begins at the age of 12, the most intense processes of longitudinal growth of the torso and lower extremities in girls are observed from 11 years. Most of the transverse dimensions within the pubertal period of ontogenesis have a pronounced progressive age dynamic. Lower thoracic size, interspinous distance, and external conjugate did not differ statistically significantly between girls of different ages during puberty.

ABSTRACT We have studied growth and adrenal dehydroepiandrosterone (DHA) responses to iv synthetic adrenocorticotrophic hormone (ACTH, Cortrosyn) in 6 girls with gonadal dysgenesis before and during treatment with lowdose ethinyloestradiol (EOe2). In all patients there was a statisfactory induction of secondary sexual characteristics including increase in breasts and pubic hair and onset of withdrawal bleeding within 6 months of therapy. Height velocity increased from 2.8 ± 0.9 cm/year pre-treatment to 5.3 ± 1.5 cm/year (P < 0.02) in the first year. There was deceleration to 1.9 ± 1.1 cm/year in the second year. There was no disproportionate advancement in bone age and thus, presumably, no loss of ultimate height. We could demonstrate no change in basal or ACTH-stimulated levels of DHA, a specific adrenal androgen, to account for the increased pubic hair and growth in these patients.

Drs. Costin and Kogut comment as follows: We were pleased to read Dr. Comas' letter in which he describes a 12-4/12-year-old girl whose clinical data suggest that she may be an example of the syndrome that we reported. The evidence for this was the occurrence of menstruation, pubic hair, and breast development when the patient was hypothyroid and disappearance of menstruation following treatment with thyroid hormone. It is not clear why Dr. Comas' patient had an increase in pubic hair and appearance of axillary hair following treatment at a time when her menstrual periods ceased; in all the reported female patients regression of the secondary sexual characteristics was noted following adequate therapy.

Despite considerable variation in the age at which puberty normally begins, a male adolescent who has demonstrated neither testicular nor pubic hair growth by 14 years of age is considered to have delayed puberty. Although such delay may indicate hypopituitarism or isolated gonadotropin deficiency, most commonly it represents a normal variation, termed "constitutional delay in growth and maturation." Such patients eventually will enter puberty and achieve normal sexual maturation and adult height. However, during adolescence, such delays may be accompanied by impaired self-image and social isolation. Under these conditions, many pediatric endocrinologists advocate short-term use of anabolic steroids. Such therapy is aimed at accelerating height velocity during the ensuing year, accompanied by the development of age-appropriate secondary sexual characteristics.

Gonadal dysgenesis is a rare cause of primary amenorrhoea ,which is a relatively common problem among teenage girls.Primary amenorrhoea occurs in patient with gonadal dysgenesis because of absence or limited ovarian function due to inappropriate development.Streak gonads are unable to produce estrogens and/or androgens,resulting in minimal to no development of secondary sexual characteristics.Adrenal androgens may induce production of pubic hair,but patient will have minimal breast development.These patients may have a family history of infertility, short stature,sensorineural deafness,ataxia,mild mental retardation or gonadoblastoma. Here two cases of primary amenorrhoea due to pure gonadal dysgenesis are presented. 1 st  one was a 18yr old girl whose mother consulted with a gynaecologist at the age of 16yr because of her worries about absence of menarche of her daughter and secondone was a 14yr old girl whose mother consulted with a gynaecologist at the age of 16yr because of absence of secondary sexual characteristics as well as menarche of her daughter. In both cases, blood test showed very high levels of follicle stimulating hormone (FSH) & luteinizing hormone (LH), low levels of oestradiol& very low level of AMH. USG findings of both cases showed a bit hypoplastic uterus and volume of ovaries were smaller than normal. A diagnostic laparoscopy with biopsy of both gonads of one case was performed.Another case did not give consent for laparoscopy.Hormonal replacement therapy was applied on them for establishment of normal menstruation and menstruation was established in both cases.  An early diagnosis is extremely important to prevent long term consequences of Gonadal dysgenesis.J Bangladesh Coll Phys Surg 2018; 36(4): 170-174

Background Worldwide incidence of obesity in children isincreasing. Obesity may have many health effects includingadvancement of sexual maturity.Objective T he aim of this study was to assess the timing ofsecondary sexual maturation in obese vs. non􀁄obese girls.Methods Subjects were 105 obese and 105 non􀁄obese girls, aged7 to 8 years who had not entered puberty. Breast and pubic hairgrowth, secondary sexual characteristics, were assessed at baselineand every 4 months for two years. Onset of puberty was defined asTanner stage for secondary sexual maturation of 2: breast Tannerstage II (B2) and/or 2: pubic hair Tanner stage II (P2). Survivalanalyses were used to estimate time to puberty in both groups.Cox regressions were used to analyze possible factors affectingsecondary sexual maturation.Results Mean onset of breast budding (B2) was 7.8 (95% CI 7.7to 7.8) years in obese girls vs. 8.6 (95% CI 8.5 to 8.6) years innon􀁄obese girls (P<O.OOl). Mean onset of pub arc he (P2) was 8.7(95% CI 8.6 to 8.8) years in obese girls vs. 9.0 (95% CI 8.9 to 9.0)years in non􀁄obese girls (P<O.OOl). Hazard ratios of obese girlsto experience an earlier secondary sexual maturation at maturitylevel B2, B3 and P2 were 1.34 (95% CI 1.19 to 1.52), 6.91 (95%CI 3.90 to 12.24) and 3.78 (95% CI 2.42 to 5.89), respectively.Conclusions Obesity was associated with earlier onset ofpuberty in girls. Obese girls entered puberty approximately 3 to9 months earlier than their non􀁄obese peers. [Paediatr Indones.2012;52:213-8].

Introduction: Puberty is a juvenile developmental period accompanied by intensive growth and acquisition of reproductive ability. The onset of puberty is influenced by many factors: genetics, neuropeptides and glycoproteins, gonadotropins, sex hormones and the child's nutrition status. Premature puberty is defined as the appearance of secondary sexual characteristics in girls before the age of 8, and in boys before the age of 9. The aim of this paper is to analyze the published results on the importance and influence of factors such as birth weight, current weight and BMI on the development of premature puberty. Results: Eating disorders caused by eating high-calorie foods lead a child to obesity, which is accompanied by premature puberty. On the other hand, conditions characterized by reduced nutrition may be accompanied by delayed puberty. According to the results of this study, children with more pronounced manifestations of precocious puberty had a significantly lower birth weight Discussion: Birth weight of less than 2500g, as well as newborns' SGA (small for gestational age), are directly related to earlier pubertal maturation. Five decades ago, Frich et al. found that reaching a body weight of 48 kg in girls is a "critical mass" for development of menarche. Conclusion: The occurrence of secondary sexual characteristics is more frequent in children with increased body weight and correlates inversely with the child's birthweight.

Introduction: Precocious puberty is defined as the appearance of secondary sexual characteristics before the age of 8 in girls and 9 in boys. Objective: Emphasize the Pediatrician´s role in the diagnosis, treatment and follow-up of patients with precocious puberty. Description: Case 1: Girl, 4 years and 11 months old. Thin and scarce pubic hair since 6 months of age. No hypertrophy of the clitoris or breast. Overweight. Normal growth rate and neurodevelopment. Examination: scarce curly pubic hair, non-estrogenic mucosa. Increase in breast size. Breast ultrasound shows lipomatosis. Bone age: 5 years. Case 2: Girl, 6 years and 11 months old. Painful bilateral and symmetric breast growth, no galactorrhea.  Oppressive, moderate and non-progressive headache. No intracranial hypertension. Pubarche, no menarche. Adequate neurodevelopment. Obese. Growth rate above the 90 percentile. Tanner III. Non-estrogenic genital mucosa. Bone age: 13 years. Gynecological ultrasound shows prepubertal uterus. Normal FSH, LH, estradiol, prolactin, TSH, T4 and cranial MRI. Treatment is initiated with leuprolide acetate. Discussion The appearance of thelarche, pubarche or menarche in patients with normal bone age, as in Case 1, constitutes an ordinary variation of puberty. However, as shown in Case 2, the presence of multiple sexual characteristics and advanced bone age must be considered as precocious puberty indicators. Pediatricians have an important role in the diagnosis and treatment of precocious puberty, as well as in the patient´s follow-up. Both anamnesis and physical examination are key to guide the diagnosis.

Efficient Elimination

In many animals, including us, the genetic sex is determined at fertilization by sex chromosomes. Seemingly, the sex determination (SD) in human and animals is determined by the amount of constitutive heterochromatin on Y chromosome via cell thermoregulation. It is assumed the medulla and cortex tissue cells in the undifferentiated embryonic gonads (UEG) differ in vulnerability to the increase of the intracellular temperature. If the amount of the Y chromosome constitutive heterochromatin is enough for efficient elimination of heat difference between the nucleus and cytoplasm in rapidly growing UEG cells the medulla tissue survives. Otherwise it doomed to degeneration and a cortex tissue will remain in the UEG. Regardless of whether our assumption is true or not, it remains an open question why on Y chromosome there is a large constitutive heterochromatin block? What is its biological meaning? Does it relate to sex determination, sex differentiation and development of secondary sexual characteristics? If so, what is its mechanism: chemical or physical? There is no scientifically sound answer to these questions.

This study was initiated on 24 prepubertal Holstein x Kankrej crossbred heifers of nearly identical age (7-9 months) and body weight (130-140 kg) at University farm to evaluate the effect of high plane of nutrition on blood biochemical and minerals profile and the age at puberty. Twelve heifers were managed under routine farm feeding (control) and the rest 12 under ideal optimum feeding regime (treatment) that included extra 1 kg concentrate, 30 g min mix and ad-lib dry fodder. The body weight and ovarian ultrasonography together with blood sampling was carried out at monthly interval from 10 to 18 months of age to study the ovarian dynamics and blood biochemical changes. High plane of nutrition to growing heifers was beneficial in reducing the age of onset of puberty (by 2-3 months) compared to routine farm fed group. The mean plasma total protein and cholesterol concentrations showed a rising trend with significant variations from 10 to 16 months of age, where it got mostly stabilized indicating adult profile. The activity of enzymes GOT and GPT also rose gradually and significantly from 10 months till 14-15 months of age, and thereafter it remained more or less static till 18 months of age. The levels of both these enzymes were higher, with lower protein and cholesterol, in control than the treatment group from 15-16 months of age onwards. The mean plasma levels of both calcium and phosphorus increased gradually and significantly with advancing age till 16-17 months of age, with little higher values in supplemented than a control group. The plasma levels of zinc, iron, copper, and cobalt also showed rising trend with significant differences between 10th and 12th-14th months of age, and from 15th to 18th months of age the levels were statistically the same in all the groups with slightly higher values in the treatment group.
