ABSTRACT

OBJECTIVES: To determine the effects of in-utero exposure to maternal SARS-CoV-2 infection on offspring's neurodevelopment during the first year of life. METHODS: We performed a prospective cohort of babies exposed to SARS-CoV-2 during pregnancy, and a control group (CG) of unexposed babies in a low-income area in Brazil. Children's neurodevelopment was assessed using the guide for Monitoring Child Development in the Integrated Management of Childhood Illness context for both groups (at 1,2,3,4,5,6, 9, and 12 months), and the Ages & Stages Questionnaire (ASQ-3) for the exposed group (EG) (at 4, 6 and 12 months). RESULTS: We followed 137 children for 1 year, 69 in the COVID-19-EG, and 68 in the CG. All mothers were unvaccinated at the time of cohort inclusion, and maternal demographics were similar in the two groups. 20.3% of EG children and 5.9% of the CG received a diagnosis of neurodevelopmental delay within 12 months of life (P = 0.013, relative risk = 3.44; 95% confidence interval, 1.19- 9.95). For the EG, the prevalence of neurodevelopment impairment using Ages & Stages Questionnaire was 35.7% at 4 months, 7% at 6 months, and 32.1% at 12 months. CONCLUSION: SARS-CoV-2 exposure was associated with neurodevelopmental impairment, and specific guidelines are needed for the follow-up of these high-risk children to mitigate the long-term effects on children's health.

ABSTRACT

Previous coronavirus epidemics were associated with increased maternal morbidity, mortality, and adverse obstetric outcomes. Reports for SARS-CoV-2 indicate that the obstetric population is at increased risk for severe illness, although there are still limited data on mild COVID-19 infection during pregnancy. To determine the association between mild COVID-19 infection during pregnancy, and maternal and neonatal outcomes, we performed a prospective cohort study among pregnant women with COVID-19 and a control group. Postnatal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. We recruited 84 pregnant women with mild COVID-19 and 88 pregnant women without COVID-19. All participants were unvaccinated. The most common acute COVID-19 symptoms were headache (82.1%), loss of smell (81%), and asthenia (77.4%). The median duration of long COVID symptoms was 60 days (interquartile range, 130). Pregnant women with a COVID-19 diagnosis were at greater risk for obstetric ultrasound abnormalities-mainly, fetal growth restriction (relative risk [RR], 12.40; 95% CI, 1.66-92.5), premature birth (RR, 2.62; 95% CI, 1.07-6.43), and postpartum depression (RR, 2.28; 95% CI, 1.24-4.21). Our results alert clinicians to the consequences of COVID-19 during pregnancy, even in mild cases, given the increased risk of ultrasound abnormalities, premature birth, long COVID symptoms, and postpartum depression. National guidelines on preventive measures and treatments should be based on scientific evidence, including attention to the impact on health and family needs during and after the COVID-19 pandemic.

ABSTRACT

OBJECTIVE: To map the transition process from the perspective of pediatricians and their adolescent patients, and to suggest a transition protocol. METHODS: This is a descriptive, cross-sectional study conducted in a pediatric outpatient clinic of a public tertiary hospital. Pediatricians answered a questionnaire about the transition process, and that was evaluated in a descriptive manner. The Transition Readiness Assessment Questionnaire (TRAQ) on health autonomy was answered by the adolescents and the analysis was performed using the χ2 and Mann-Whitney tests. p<0.05 were considered significant. RESULTS: 31 pediatricians (16 residents, 15 supervisors) were enrolled, with a mean age of 40.1 (±16.9), 87% women, with years working in Pediatrics ranging from 2 to 45 years (median of 5 years). Most doctors agreed that there was no transition plan, but they stimulated the patient's autonomy and talked to the patient and family members about any existing chronic diseases. A total of 102 adolescent patients participated, with a median age of 15; 56% were female. The TRAQ median was 58, with similar scores between females and males, and higher scores in those older than 16 years of age (Mann-Whitney U test, p=0.01). The patients reported ease in face-to-face communication with their doctors, but great difficulty in talking about health issues over the phone. CONCLUSIONS: Even without a transition protocol, adolescents developed several self-care skills as they aged. The lack of a transitional protocol led to conflicting opinions, which reinforces the need for improvement. We suggest a flowchart and transition protocol.

ABSTRACT

OBJECTIVE: The aim was to adapt an instrument that evaluates the relationship between young individuals and health professionals to the Brazilian population, which will be called the Escala de Avaliação de Vínculo entre Jovens e Profissionais de Saúde (Youth Connectedness to Provider scale). METHOD: The questionnaire known as the Youth Connectedness to Provider scale consists of seven Likert-like questions. The translation, back-translation, evaluation by ten specialists, and pre-test with 43 adolescents and young adults aged between 10 and 24 years were performed to assess the clarity and reliability of meanings. The content validity index was calculated for each question. Subsequently, the clinical validation was performed with 83 patients aged 10-24 years old and Cronbach's alpha coefficient was calculated. RESULTS: A content validity index >0.8 (considered satisfactory) was obtained for all items analyzed by experts and adolescents. At the clinical validation, it showed a high internal consistency (Cronbach's alpha=0.76). The questions showed a good correlation, except for the question about judgment (Spearman's rho=0.03-0.19). CONCLUSIONS: The scale adaptation showed an adequate agreement rate at the translation evaluation and a good reliability index in the questions. This instrument provides information on strengths and topics that require more attention from professionals to improve the relationship with their patients; it can be a valuable parameter in assessing the medical consultation quality.

ABSTRACT

Abstract Objectives: To determine the prevalence of congenital hypothyroidism in children with filter-paper blood-spot TSH (b-TSH) between 5 and 10 µIU/mL in the neonatal screening. Methods: This was a retrospective study including children screened from 2003 to 2010, with b-TSH levels between 5 and 10 µIU/mL, who were followed-up during the first two years of life when there was no serum TSH normalization. The diagnosis of congenital hypothyroidism was defined as serum TSH ≥10 µIU/mL and start of levothyroxine treatment up to 2 years of age. Results: Of the 380,741 live births, 3713 (1.04%) had filter paper TSH levels between 5 and 10 µIU/mL and, of these, 339 (9.13%) had congenital hypothyroidism. Of these, 76.11% of the cases were diagnosed in the first three months of life and 7.96% between 1 and 2 years of age. Conclusion: The study showed that 9.13% of the children with b-TSH levels between 5 and 10 µIU/mL developed hypothyroidism and that in approximately one-quarter of them, the diagnosis was confirmed only after the third month of life. Based on these findings, the authors suggest the use of a 5 µIU/mL cutoff for b-TSH levels and long-term follow-up of infants whose serum TSH has not normalized to rule out congenital hypothyroidism.


Resumo Objetivos: Determinar a prevalência de hipotireoidismo congênito em crianças com TSH em papel filtro (TSH-f) entre 5 e 10 µUI/mL na triagem neonatal. Métodos: Estudo retrospectivo que incluiu crianças triadas de 2003 a 2010, com TSH-f entre 5 e 10 µUI/mL, acompanhadas nos dois primeiros anos de vida quando não houve normalização do TSH sérico. O diagnóstico de hipotireoidismo congênito foi definido como TSH sérico igual ou superior a 10 µUI/mL e início de tratamento com levotiroxina até os dois anos. Resultados: Dos 380.741 nascidos vivos triados, 3.713 (1,04%) apresentaram TSH-f entre 5 e 10 µUI/mL e, desses, 339 (9,13%) tinham hipotireoidismo congênito. Desses, 76,11% dos casos foram diagnosticados nos primeiros três meses de vida e 7,96% entre um e dois anos. Conclusão: O estudo mostra que 9,13% das crianças com TSH-f entre 5 e 10 µUI/mL desenvolveram hipotireoidismo e que em cerca de um quarto delas o diagnóstico só se confirmou após o terceiro mês de vida. Com base nesses achados, sugere-se, para descartar o hipotireoidismo congênito, o uso do ponto de corte de TSH-f de 5 µUI/mL e o acompanhamento em longo prazo dos lactentes cujo TSH sérico não tenha se normalizado.

ABSTRACT

Seizure models have demonstrated that neuroinflammation and neurodegeneration are preponderant characteristics of epilepsy. Considering the lack of clinical studies, our aim is to investigate the extrinsic pathway of apoptosis in pharmacoresistant temporal lobe epilepsy (TLE) associated with hippocampal sclerosis (HS) patients, TLE(HS). By a specific death receptor-mediated apoptosis array plate, 31 upregulated targets were revealed in the sclerotic hippocampus from TLE(HS) patients. Amongst them are the encoding genes for ligands (FASLG, TNF, and TNFSF10) and death receptors (FAS, TNFRSF1A, TNFRSF10A, and TNFRSF10B). In addition, we evaluated the hippocampal relative mRNA expression of the two TNF receptors, TNFRSF1A and TNFRSF1B, in patients, being both upregulated (n = 14; P < 0.01 and P < 0.04, resp.) when compared to the post mortem control group (n = 4). Our results have clearly suggested that three different death receptor apoptotic systems may be associated with the maintenance and progression of TLE-associated HS: (1) TNF-TNFRSF1A, (2) FASLG-FAS, and (3) TNFSF10-TNFRSF10A/B. Their effects on epilepsy are still scarcely comprehended. Our study points out to TNF and TNF receptor superfamily pathways as important targets for pharmacological studies regarding the benefits of an anti-inflammatory therapy in these patients.

ABSTRACT

Mutations in the Bruton agammaglobulinemia tyrosine kinase (BTK) gene are responsible for X-linked agammaglobulinemia (XLA). Unfolded or misfolded proteins can trigger stress pathways in the endoplasmic reticulum (ER), known as unfolded protein response (UPR). The aim was to clarify the involvement of UPR in XLA pathophysiology. By reverse transcription-quantitative PCR, we evaluated the expression of BTK and 12 UPR-related genes in eight patients. Moreover, we assessed the BTK protein expression and pattern in the patients' monocytes by flow cytometry and fluorescence immunocytochemistry. We found a reduced BTK expression in patients with stop codon mutations (P < 0.02). However, missense mutations did not affect BTK expression. Flow cytometry showed a reduction of BTK in patients which was corroborated by an absent or nonfunctional protein synthesis revealed by immunocytochemistry. In contrast with the other UPR-related genes, X-box binding protein 1 (XBP1) was markedly upregulated in the patients (P < 0.01), suggesting Toll-like receptor (TLR) activation since BTK directly interacts with TLRs as a negative regulator and XBP1 can be activated in direct response to TLR ligation. Different BTK mutations can be identified by the BTK expression. Inasmuch as UPR-related genes were downregulated or unaltered in patients, we speculate the involvement of the TLRs-XBP1 axis in the XLA pathophysiology. Such data could be the basis for further studies of this novel pathomechanism concerning XLA.

ABSTRACT

Neonatal severe hyperparathyroidism (NSHPT) is a rare disorder characterized by major hypercalcemia, elevated parathyroid hormone levels, and marked enlargement of multiple parathyroid glands, usually associated with germline mutations in the calcium receptor gene CASR. However, little is known about the outgrowth of parathyroid tumors in NSHPT, including whether they represent monoclonal or polyclonal expansions. We sought to examine the clonality of parathyroid tissues resected from a patient with NSHPT and biallelic CASR mutations. DNA from two distinct parathyroid tumors resected from a girl with NSHPT, plus polyclonal/monoclonal control samples, were subjected to analyses of clonality by two independent methods, X-chromosome inactivation analysis at the androgen receptor locus (HUMARA) and BAC array comparative genomic hybridization (CGH). Both parathyroid tumor samples revealed polyclonal patterns by X-inactivation analysis, with polyclonal and monoclonal controls yielding the expected patterns. Similarly, by BAC array CGH, neither parathyroid sample contained monoclonal copy number changes and both appeared identical to the patient-matched polyclonal controls. Our observations provide direct experimental evidence that the markedly enlarged parathyroid tumors in the setting of NSHPT constitute polyclonal, generalized hyperplastic growths rather than monoclonal neoplasms.

ABSTRACT

STUDY OBJECTIVE: To compare cervical lengths of adolescents and adults in mid-gestation. DESIGN: An analytical, observational, and cross-sectional study. SETTING: Public health system in the city of Blumenau, Brazil. PARTICIPANTS: Primigravidae adolescents under the age of 16 and adults over age 20 (n = 40/group) were systematically sampled. INTERVENTIONS: Cervical measurements were performed between 21 and 24 weeks of gestation through transvaginal ultrasonography using a previously validated method. MAIN OUTCOME MEASURES: Mean cervical length (Mann-Whitney test) and percentage of cervices below 25 mm (Fisher exact test). RESULTS: For adolescents and adults, average uterine cervix lengths were 28 ± 6.6 mm 33 ± 4.1 mm (P < .0001), respectively, and the proportion of cervixes below 25 mm were 27.5% and 7.5% (P < .02), respectively. In addition, adolescents had significantly lower gynecologic age, education, and family income than adults. CONCLUSION: Primigravida adolescents under the age of 16 have shorter cervices than adults, and a higher percentage of adolescents have cervices shorter than 25 mm. This may be associated with the higher risk of preterm birth observed in adolescents and suggests that this population requires special attention in prenatal care.

ABSTRACT

BACKGROUND: Previous research in animal seizure models indicates that the pleiotropic cytokine TNF is an important effector/mediator of neuroinflammation and cell death. Recently, it has been demonstrated that TNF downregulates Klotho (KL) through the nuclear factor kappa B (NFkB) system in animal models of chronic kidney disease and colitis. KL function in the brain is unclear, although Klotho knockout (Kl-/-) mice exhibit neural degeneration and a reduction of hippocampal synapses. Our aim was to verify if the triad KL-NFKB1-TNF is also dysregulated in temporal lobe epilepsy associated with hippocampal sclerosis (TLE(HS)) patients. FINDINGS: We evaluated TNF, NFKB1 and KL relative mRNA expression levels by reverse transcription quantitative PCR (RT-qPCR) in resected hippocampal tissue samples from 14 TLE(HS) patients and compared them to five post mortem controls. Four reference genes were used: GAPDH, HPRT1, ENO2 and TBP. We found that TNF expression was dramatically upregulated in TLE(HS) patients (P <0.005). NFKB1 expression was also increased (P <0.03) while KL was significantly downregulated (P <0.03) in TLE(HS) patients. Hippocampal KL expression had an inverse correlation with NFKB1 and TNF. CONCLUSIONS: Our data suggest that, similar to other inflammatory diseases, TNF downregulates KL through NFkB in TLE(HS) patients. The remarkable TNF upregulation in patients is a strong indication of hippocampal chronic inflammation. Our finding of hippocampal KL downregulation has wide implications not only for TLE(HS) but also for other neuronal disorders related to neurodegeneration associated with inflammation.

ABSTRACT

We show that combined multimodal nonlinear optical (NLO) microscopies, including two-photon excitation fluorescence, second-harmonic generation (SHG), third harmonic generation, and fluorescence lifetime imaging microscopy (FLIM) can be used to detect morphological and metabolic changes associated with stroma and epithelial transformation during the progression of cancer and osteogenesis imperfecta (OI) disease. NLO microscopes provide complementary information about tissue microstructure, showing distinctive patterns for different types of human breast cancer, mucinous ovarian tumors, and skin dermis of patients with OI. Using a set of scoring methods (anisotropy, correlation, uniformity, entropy, and lifetime components), we found significant differences in the content, distribution and organization of collagen fibrils in the stroma of breast and ovary as well as in the dermis of skin. We suggest that our results provide a framework for using NLO techniques as a clinical diagnostic tool for human cancer and OI. We further suggest that the SHG and FLIM metrics described could be applied to other connective or epithelial tissue disorders that are characterized by abnormal cells proliferation and collagen assembly.

ABSTRACT

Deficiency of the enzyme P450 oxidoreductase is a rare form of congenital adrenal hyperplasia with characteristics of combined and partial impairments in steroidogenic enzyme activities, as P450 oxidoreductase transfers electrons to CYP21A2, CYP17A1, and CYP19A1. It results in disorders of sex development and skeletal malformations similar to Antley-Bixley syndrome. We report the case of a 9-year-old girl who was born with virilized genitalia (Prader stage V), absence of palpable gonads, 46,XX karyotype, and hypergonadotropic hypogonadism. During the first year of life, ovarian cyst, partial adrenal insufficiency, and osteoarticular changes, such as mild craniosynostosis, carpal and tarsal synostosis, and limited forearm pronosupination were observed. Her mother presented severe virilization during pregnancy. The molecular analysis of P450 oxidoreductase gene revealed compound heterozygosis for the nonsense p.Arg223*, and the novel missense p.Met408Lys, inherited from the father and the mother, respectively. Arq Bras Endocrinol Metab. 2012;56(8):578-85.


A deficiência da enzima P450 oxidorredutase é uma forma rara de hiperplasia congênita da adrenal com características de inibição combinada e parcial de enzimas esteroidogênicas, pois a enzima P450 oxidorredutase participa da transferência de elétrons para as enzimas CYP21A2, CYP17A1 e CYP19A1. Essa deficiência causa um distúrbio do desenvolvimento do sexo e alterações esqueléticas semelhantes às da síndrome de Antley-Bixley. Relatamos o caso de uma menina, atualmente com 9 anos de idade, que apresentava ao nascimento genitais virilizados (Prader 5) sem gônadas palpáveis, com cariótipo 46,XX e hipogonadismo hipergonadotrófico. No primeiro ano de vida, foram observados cisto ovariano, insuficiência adrenal parcial e alterações osteoarticulares como leve craniossinostose, sinostose carpal e tarsal e limitação de pronossupinação dos membros superiores. Sua mãe apresentou intensa virilização durante a gestação. O estudo molecular do gene P450 oxidorredutase revelou a heterozigose composta das mutações nonsense p.Arg223* e da missense nova p.Met408Lys, herdadas do pai e da mãe, respectivamente.

ABSTRACT

BACKGROUND AND AIM: Turner syndrome (TS) patients have an increased risk of weight gain and metabolic syndrome. To date, it is unknown what factors are involved in this metabolic process, even though it is recognized that TS patients are frequently born small-for-gestational age. The aim of this study was to evaluate the correlation between lipid and glucose profiles with being overweight and birth weight and length in TS patients. STUDY DESIGN: This was a cross-sectional study. SUBJECTS AND OUTCOME MEASURES: Serum glucose, insulin (HOMA-IR), total cholesterol, and triglycerides were measured in 64 patients with TS. Data regarding birth weight and length and current body mass index (BMI) were also evaluated. RESULTS: Total cholesterol showed a significant negative correlation with birth weight and a positive correlation with BMI; triglycerides showed significant negative correlation with birth weight and length and a positive correlation with BMI; and HOMA-IR showed a significant negative correlation with birth weight and length. Low birth weight and a high BMI were predictive for 28% of total cholesterol and triglycerides; and low birth weight for 22% of HOMA-IR. CONCLUSIONS: Lipid profile was correlated with a high current BMI and low birth weight and length in TS patients and glucose profile only with low birth weight. Thus far, growth retardation may play a role in metabolic derangements in this group of patients, being considered another example of fetal programming.

OBJECTIVE: To evaluate insulin resistance and lipid profile in women with congenital adrenal hyperplasia (CAH) caused by classical 21-hydroxylase deficiency (21OHD), and their association with body mass index (BMI) and corticosteroid dosage. SUBJECTS AND METHODS: We assessed BMI, waist circumference, current glucocorticoid dosage, glucose, insulin and lipid profile in eighteen young women (mean ± SD, 19.3 ± 3.0 years) with 21OHD CAH. RESULTS: BMI was normal in 12 patients, 5 of them were overweight, and 1 was obese. Waist circumference was high in 7 patients. Fasting insulin and HOMA-IR were elevated in seven and eight patients, respectively. Total cholesterol and triglycerides were high in only two patients, and HDL-cholesterol was low in four. Insulin resistance was not associated with BMI, waist circumference or glucocorticoid dose. CONCLUSIONS: Young women with 21OHD CAH had infrequent dyslipidemia, but had a higher prevalence of insulin resistance and central obesity, that were independent of BMI or corticosteroid dosage.


OBJETIVO: Avaliar a presença de resistência insulínica e dislipidemia em mulheres com hiperplasia adrenal congênita (HAC) por deficiência da 21-hidroxilase (21OHD) e investigar a associação com índice de massa corporal (IMC) e dose de glicocorticoide prescrita. PACIENTES E MÉTODOS: Em 18 mulheres jovens (média ± DP, 19,3 ± 3,0 anos), avaliamos IMC, circunferência abdominal, dose de glicocorticoide, glicemia, insulinemia e perfil lipídico. RESULTADOS: O IMC foi normal em 12 pacientes; 5 apresentavam sobrepeso e 1 apresentou obesidade. Circunferência abdominal estava aumentada em 7 pacientes. Insulinemia de jejum e HOMA-IR estavam elevados em 7 e 8 pacientes, respectivamente. Apenas 2 pacientes apresentaram aumento de colesterol total ou de triglicérides e 4, diminuição dos níveis de HDL-colesterol. Resistência insulínica não apresentou associação com IMC, circunferência abdominal ou dose de glicocorticoide prescrita. CONCLUSÃO: Mulheres jovens com CAH 21OHD apresentaram pouca dislipidemia, mas tiveram alta prevalência de resistência insulínica e obesidade central, independentemente do IMC e da dose de glicocorticoide prescrita.

ABSTRACT

This study analyzes the body composition of young adult women with Turner syndrome (TS) either treated or not treated with recombinant human growth hormone (rhGH) and compares them with a group of healthy women. Fifty-two non-treated TS patients (23.0 ± 5.8 years), 30 treated with rhGH (21.5 ± 1.5 years), and 133 healthy young adult women (22.9 ± 3.2 years) were evaluated regarding height (H) and weight, body mass index (BMI), brachial perimeter and tricipital cutaneous fold (fat and lean areas at the arm), sitting height (SRH = sitting height/H × 100), leg length (leg/H), waist and hip circumferences (waist/hip), and bioimpedance (percentages of water, lean mass, and fat mass). Age at start of rhGH therapy varied from 7.8 to 15.1 years (10.0 ± 1.3 years), duration of treatment from 2.8 to 8.2 years (3.7 ± 1.5 years), and the mean dose was 0.42 mg/kg/w (from 0.32 to 0.50 mg/kg/w). Body composition (except height) did not differ between TS groups, but there were differences when compared to the control group: weight and sitting height were lower in TS patients; and BMI, SHR, and leg/H were higher. There was an association between all groups with regards to BMI, waist, SHR, and leg/H, but not in percentage of fat mass. SHR was positively correlated with BMI, waist, hip, and percentage of fat mass. This sample of TS patients (with and without rhGH therapy) did not differ in BMI or body composition. However, there were differences between patients with TS patients and normal healthy women. Regardless of rhGH therapy, TS patients should be monitored, particularly for sitting height, SHR, leg length, leg/H, and waist/hip.

ABSTRACT

OBJETIVO: Os cistos aracnoides são achados raros. Em 10 por cento dos casos, sua localização é supraselar e ocorrem quase exclusivamente em crianças. Em geral, apresentam manifestações neurológicas e visuais, sendo incomum a puberdade precoce central como sinal clínico de sua presença. DESCRIÇÃO DO CASO: Menina avaliada aos dois anos e sete meses por telarca iniciada com um ano e oito meses e pubarca e axilarca com dois anos, com aumento da velocidade de crescimento (13cm/ano) e da idade óssea (sete anos e um mês). Ao exame, apresentou peso de 22,6kg (Z+4,0), estatura de 106cm (Z+3,5) e Tanner de M3P2. Exames realizados: teste de estímulo com GnRH (LH basal 8,3 UI/L, pico aos 30 minutos 94,3 UI/L; FSH basal=10,1 UI/L, pico aos 30 minutos 29,5 UI/L), ressonância nuclear magnética de crânio com cisto aracnoide supraselar e demais testes de função hipofisária normais. Foi iniciado tratamento com análogo de GnRH. Atualmente, aos quatro anos e três meses com estadio puberal M3P2, velocidade de crescimento e desenvolvimento neuropsicomotor normais para a idade. COMENTÁRIOS: A puberdade precoce central pode ser manifestação única de um cisto aracnoide, sendo essenciais o diagnóstico e o tratamento precoces, além de seguimento prolongado, uma vez que outras disfunções hipofisárias podem ocorrer tardiamente.


OBJECTIVE: Arachnoid cysts (AC) are a rare finding; 10 percent of them are suprasellar and occur almost exclusively in children. They are frequently associated with neurological and visual manifestations. Central precocious puberty as a sole manifestation is uncommon. CASE DESCRIPTION: Girl evaluated at the age of two years and seven months. She started breast development at the age of one year and eight months, pubic and axillary hair at the age of two years, with growth velocity acceleration (13cm/year) and increased bone age (seven years and one month). On exam: weight: 22.6kg (Z+4.0), height: 106cm (Z+3.5) and puberal stage of B3P2. The GnRH stimulus test was performed (basal LH 8.3 IU/L, at 30 minutes 94.3 IU/L; FSH basal=10.1 IU/L, at 30 minutes 29.5 IU/L). Nuclear Magnetic Resonance of the skull showed a suprasellar arachnoid cyst. Others stimulation tests were performed and excluded pituitary deficiencies. Treatment with a GnRH analog was started. At the age of four years and three months, she was B3P2, with normal growth velocity and neurologic development. COMMENTS: Central precocious puberty can be the only manifestation of AC. It is essential to establish early diagnosis and treatment. A prolonged follow up is recommended, since late pituitary dysfunctions can occur.
