Standards for pubertal stages of breasts, pubic hair and genitalia are given and emphasis of these pubertal changes.</p><p>Measurement of developmental age is discussed. The Greulich—Pyle and Tanner-Whitehouse methods for skeletal age are described. These methods can be used for predicting adult height which is useful both in diagnosis and in following the effects of treatment. In diagnosis the predicted adult height is compared to the range of expected heights in the children of the particular pair of parents concerned (the so-called ‘target’ range of heights) to see if smallness is simply due to delay. Change in Tanner-Whitehouse predicted height occurs on successful treatment of, for example, growth hormone deficient short stature, and is thus a guide to the success of treatment. Standards are also given for height of children from age two to nine inclusive, with allowance for height of their parents.</p></div>","PeriodicalId":10454,"journal":{"name":"Clinics in Endocrinology and Metabolism","volume":"15 3","pages":"Pages 411-451"},"PeriodicalIF":0.0,"publicationDate":"1986-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0300-595X(86)80005-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14656082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observation of a defect in the neuroregulatory control of GH secretion in CNS-irradiated humans and animals led to the hypothesis of a disorder in neurosecretion, GHND, as a cause for short stature.

However, the responses of the hair follicles and their associated glands vary greatly between sites and between individuals.</p><p>On the face, trunk and extremities the most important role of testosterone is to increase the period of activity, the anagen phase, of the hair follicle, though it also increases the rate of growth, thickness, extent of medullation and pigmentation of the hair. These effects involve high levels of hormone and its conversion to 5α-dihydrotestosterone in the target organ.
