INTRODUCTION: Trichomycosis is a superficial infection caused by Corynebacterium flavescens, which regularly affects axillary, and to a a lesser extent, pubic, scrotal and intergluteal, and exceptionally, head hairs or trichomycosis capitis (TC). This condition is characterised by the formation of bacterial nodules. Clinically, it can be confused with white piedra or pediculosis. The diagnosis is made by microscopic and dermoscopic observation and confirmed by culture. OBJECTIVE: To present a case of TC in an infant and illustrate the microscopic, dermoscopic, and ultrastructural characteristics...

BACKGROUND: Birth order has been proposed as a cardiovascular risk factor, because the lower birth weight and greater infant weight gain typical of firstborns could programme metabolism detrimentally. METHODS: We examined the associations of birth order (firstborn or laterborn) with birth weight-for-gestational age, length/height and body mass index (BMI) z-scores during infancy, childhood, and puberty using generalized estimating equations, with age at pubertal onset using interval-censored regression and with age-, sex- and height-standardized blood pressure, height and BMI z-scores at 13 years using linear regression in a population-representative Chinese birth cohort: "Children of 1997" (n = 8,327)...

Trichomycosis (trichobacteriosis) is an asymptomatic superficial bacterial colonization of the hair shaft that is clinically characterized by pale yellowish, reddish or blackish sticky, cylindrical concretions surrounding the hair shaft in the axillary or pubic region. As far as we know, the first and only case of trichomycosis capitis was reported in a 8-year-old boy in 2011. We encountered no cases of trichomycosis in infancy in the literature. The current case displays an atypical presentation of trichobacteriosis involving head hair in a 10-month-old male infant...

To examine the association of breastfeeding or its duration with timing of girls' pubertal onset, and the role of BMI as a mediator in these associations. A population of 1,237 socio-economically and ethnically diverse girls, ages 6-8 years, was recruited across three geographic locations (New York City, Cincinnati, and the San Francisco Bay Area) in a prospective study of predictors of pubertal maturation. Breastfeeding practices were assessed using self-administered questionnaire/interview with the primary caregiver...

Although functional hyperprolactinemia originating in the hypothalamus has been observed, there have so far been few reports of this condition occurring in children. This report describes a 1-yr-and-4-mo old boy with hyperprolactinemia due to functional disorder of the hypothalamic region. He was referred to our hospital because of left gynecomastia which had been observed for one month. His left breast development was stage II, right breast stage I, and pubic hair stage I by Tanner stages, and his bilateral testicular volume was 1 ml...

A male infant was diagnosed with partial androgen insensitivity caused by a novel mutation in the androgen receptor. At 3.5 months of age, he received 100 mg of testosterone intramuscularly over the course of 3 months to increase phallic size. He developed pubic hair after 5 months and signs of progressive central precocious puberty when re-examined at 17.5 months, which subsequently was suppressed with depot leuprolide.

CONTEXT: Ig superfamily member 1 (IGSF1) deficiency was recently discovered as a novel X-linked cause of central hypothyroidism (CeH) and macro-orchidism. However, clinical and biochemical data regarding growth, puberty, and metabolic outcome, as well as features of female carriers, are scarce. OBJECTIVE: Our objective was to investigate clinical and biochemical characteristics associated with IGSF1 deficiency in both sexes. METHODS: All patients (n = 42, 24 males) from 10 families examined in the university clinics of Leiden, Amsterdam, Cambridge, and Milan were included in this case series...

CONTEXT: Testicular adrenal rest tumors (TARTs) and hypogonadotropic hypogonadism are the two most common causes for male infertility in classic 21-hydroxylase deficiency. Current hypotheses suggest the quality of disease control to be one of the main pathogenic factors for TART development. OBJECTIVE: The aim was to study long-term predictors for TART development in a retrospective longitudinal study. DESIGN: Fifty men with classic 21-hydroxylase deficiency (31 salt wasting, 19 simple virilizing) were investigated...

BACKGROUND: Despite the number of reported data concerning idiopathic central precocious puberty (CPP) in girls, major questions remain including its diagnosis, factors, and indications of gonadotropin releasing hormone (GnRH) analog treatment. METHODS: A retrospective, single-center study was carried out on 493 girls with CPP. RESULTS: Eleven girls (2.2%) were aged less than 3 years. Breast development was either isolated (Group 0, n = 99), or associated with one sign, pubic hair development, growth rate greater than 2 standard deviation score (SDS) or bone age (BA) >2 years above chronological age, (Group 1, n = 187), two signs (Group 2, n = 142) or three signs (Group 3, n = 65)...

Nonfamilial cardiomyopathies in childhood have been only sporadically ascribed to endocrine disorders. We report on a 4-month-old male infant presenting with Cushing's syndrome associated with excessive body weight (8.9 kg; >97th percentile) and features of virilization (Tanner stage 2 for pubic hair development). Abdominal sonography showed a large adrenal tumor. Echocardiography revealed myocardial hypertrophy with severe subaortic obstruction. Blood tests showed excessive androgen and cortisol serum levels with absent circadian rhythm as well as suppressed corticotropin...

Androgen replacement therapy for male hypogonadism may be prescribed utilizing intramuscular, oral or more recently, topical formulations. With topical formulations, there is a risk of person-to-person transmission if appropriate precautions are not taken. We describe two cases of virilization in pre-pubertal children following passive transfer of paternal topical testosterone. A 21 month old male was referred with a 6 week history of pubic hair, phallic growth, and linear growth spurt. Genital examination revealed Tanner stage 2 pubic hair and Tanner stage 3 phallic development, which was discordant with the pre-pubertal testicular size (2 mL bilaterally)...

3-M syndrome is an underdiagnosed autosomal recessive disorder characterized by severe pre- and postnatal growth retardation with minimal dysmorphic features and distinguishing radiological findings. We report a patient who was first admitted at 7.5 years of age. He was born to consanguineous parents with a birth weight of 2250 g. Physical examination revealed a severe short stature (height, 95 cm; SD score -5.64) and minimal dysmorphic features. Biochemistry, endocrine work-up, and karyotype were normal. Reevaluation at 16...

Adrenocortical tumour is rare in children. We report on a female infant with adrenocortical carcinoma presenting with pseudoprecocious puberty at the age of two. She had a history of gradually increasing public hair growth after birth. Physical examination showed signs of virilisation such as pubic hair growth and hirsutism with evidence of facial hair growth. On biochemical evaluation, DHEA-S, 17-OH progesterone, and testosterone levels were elevated. An abdominopelvic spiral computed tomography (CT) scan with intravenous contrast identified a well-defined heterogeneously enhanced mass with areas of necrosis in the right adrenal gland and downward displacement of the underlying kidney...

UNLABELLED: Acne vulgaris is a chronic inflammatory disease with a complex pathogenesis that affects predominantly adolescents. The aim of the study was to investigate the interrelations between the presence of acne and several variables associated with somatic growth, pubertal maturation, and environmental conditions (altitude and regions of residence). A population sample of 6,200 clinically healthy boys (0-19 years) was examined and the presence of acne was determined. Height, weight, testicular volumes, penile length and circumference, as well as pubic hair were also measured...

In a series of field surveys of wild Javan lutungs (Trachypithecus auratus sondaicus) conducted at Pangandaran Nature Reserve in West Java, Indonesia, from 2011 to 2012, we tried to use a method of individual identification by using individual-specific patterns of dark pigmentation in the pubic area. During the 2011 dry season, we used a digital SLR camera with a 400-mm telephoto lens to photograph the pubic area of each individual of a habituated group. These photographs were the basis for identifying 14 different adult females...

Hypothalamic hamartoma (HH) is one of the most important causes of central precocious puberty in male children. Hamartomas are malformations composed of ectopic gonadotropic hormone (GnRH) neurons which secrete pulsatile gonadotropin releasing hormone. They are generally observed in children under 3 years. A case of 11/3 year-old male child presented with premature development of secondary sexual characters i.e., growth of pubic and axillary hair, enlargement of penis and acne over the face for the last 5 months...

Although PTC most frequently occurs in obese females of childbearing age, the syndrome occurs in children as well.(3),(5) Prepubertal children with PTC have a lower incidence of obesity compared with adults and there is no sex predilection. The onset of puberty is best defined by the onset of secondary sexual characteristics such has menarche, pubic hair, and breast development. Children with PTC have a higher incidence of associated conditions and cranial nerve deficits compared with adults. Similar to adult patients, children are at risk for the development of permanent visual loss...
