    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and "on-time" puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    Gender identity is the sense of belonging that one feels for a particular sex psychologically and socially, independent of one's biological sex. There is much less systematic data on gender identity in females with congenital adrenal hyperplasia (CAH). We report a case of non-classical CAH presenting as a case of gender identity disorder.

    Non-classical congenital adrenal hyperplasia (NCAH) is a morbid condition sustained by the reduced function of one of the enzymes involved in the adrenal steroid biosynthesis pathway, mainly the 21-hydroxylase. Different degrees of enzyme activity impairment determine different clinical pictures, with childhood or post-pubertal onset. The aim of this study was to evaluate the relationship between genotype, phenotype, and adrenal hormonal levels in a group of 66 patients affected by NCAH attending outpatient pediatric or endocrinological Clinics. Our findings show that age at pubarche/menarche was significantly younger, height SD score) and Δ bone age-chronological age were significantly higher in patients with a more severe enzyme activity impairment, while cutaneous androgenization and menstrual irregularities in post-pubertal girls were not related to the grading of genotype.

    During childhood, the main aims of the medical treatment of congenital adrenal hyperplasia (CAH) secondary to 21-hydroxylase are to prevent salt loss and virilization and to attain normal stature and normal puberty. As such, there is a narrow therapeutic window through which the intended results can be achieved. In adulthood, the clinical management has received little attention, but recent studies have shown the relevance of long-term follow-up of these patients. The aims here are to review the multiple clinical, hormonal and metabolic abnormalities that could be found in adult CAH patients as such a decrease in bone mineral density, overweight and disturbed reproductive functions. In women with classic CAH, a low fertility rate is reported, and is probably the consequence of multiple factors including neuroendocrine and hormonal factors, feminizing surgery, and psychological factors. Men with CAH may present hypogonadism either through the effect of adrenal rests or from suppression of gonadotropins resulting in infertility. Therefore a multidisciplinary team with knowledge of CAH should carefully follow up these patients, from childhood through to adulthood, to avoid these complications and to ensure treatment compliance and tight control of the adrenal androgens.

    Full Text Available Introduction: Children with congenital adrenal hyperplasia (CAH provide us an opportunity to study the clinical effects of androgen excess in humans. We studied the sequence of pubertal development in girls with congenital adrenal hyperplasia initiated on treatment at different ages, to assess the effects of androgen exposure on the Hypothalamic-Pituitary-Ovarian (HPO axis. Materials and Methods: Girls more than 18 years of age, with CAH, on follow-up at this hospital were the subjects for this study. Details of history, physical findings, laboratory evaluation, and medication were noted from their case records and verified from the patients and their / parents, in addition to assessment of their present health status. Result: We studied 24 patients of classical CAH (SW-2, SV-22, average age - 24.5 ± 6.6 years. All had varying degrees of genital ambiguity (Prader stage 3 (n = 13, Prader stage 2 (n = 10, Prader stage 1 (n = 1. Among them were13 girls, who were started on steroids after eight years of age. Girls who received treatment from infancy and early childhood had normal pubertal development (mean age at menarche 11.4 ± 1.7 years. Hirsutism was not a problem among them. Untreated children had progressive clitoral enlargement throughout childhood, developed pubic hair at around three to six years of age, and facial hair between nine and eleven years. Plasma testosterone ranged from 3 to 6 ng / ml prior to treatment. Six of the 13 untreated CAH girls had subtle breast development starting at ages 11 - 16 years and three had spontaneous infrequent vaginal bleeding starting at ages 11 - 17. Steroid supplementation initiated pubertal changes in older girls in two-to-six months′ time. Conclusion: There was a delay in HPO axis maturation (as evidenced by delayed pubertal development in the absence of treatment in girls with CAH. This could be corrected with steroid supplementation.

    The psychoendocrinology of the development of normal gender identity and its variations is poorly understood. Studies of gender development in individuals born with endocrinologically well-characterized intersex conditions are heuristically valuable for the disaggregation of factors that are acting in concert during normal development. Four 46,XX individuals with classical congenital adrenal hyperplasia (CAH) and atypical gender identity entered a comprehensive research protocol including systematic interviews and self-report inventories on gender role behavior and identity, sexual history, and psychiatric history. Some of the data on gender variables were compared to data from 12 CAH women with the salt-wasting variant (CAH-SW) with female gender identity. The four patients (ages 28, 35, 38, and 30 years) represented three different subtypes of classical early-onset CAH: 21-OH deficiency, simple virilizing (CAH-SV); 21-OH deficiency, salt-wasting (CAH-SW); and 11-beta-OH deficiency. Their medical histories were characterized by delay beyond infancy or lack of surgical feminization of the external genitalia and progressive virilization with inconsistent or absent glucocorticoid replacement therapy. Although three patients had undergone one or more genital surgeries, all had retained at least some orgasmic capacity. In regard to childhood gender-role behavior, the four gender-change patients tended to be more masculine or less feminine than (behaviorally masculinized) CAH-SW controls. All patients were sexually attracted to females only. The process of gender change was gradual and extended well into adulthood. The most plausible factors contributing to cross-gender identity development in these patients appeared to be neither a particular genotype or endocrinotype nor a sex-typing bias on the part of the parents but a combination of a gender-atypical behavioral self-image, a gender-atypical body image, and the development of erotic attraction to women.

    Full Text Available Aim of the Study: To evaluate bone mineral density (BMD and levels of bone turnover markers in Egyptian children with classic congenital adrenal hyperplasia (CAH caused by 21-hydroxylase deficiency and its relationship with disease-related variables. Patients and Methods: The study population consisted of 28 children from Upper Egypt with classic CAH, their mean age 8.3 ± 2.4 years and 28 age and sex matched healthy control. They were subjected to measurement of BMD of lumbar spines (L1-L4 and femoral neck using dual-energy-X-ray absorptiometry (DXA and laboratory evaluation of bone turnover markers including Osteocalcin and serum receptor activator of nuclear factor αB-ligand (RANKL. Result: Children with CAH had significantly lower bone-mineral density (BMD for both, vertebrae and femoral neck than controls. This difference is more obvious in children with poor control and in those receiving prednisone therapy. There was a significantly lower serum osteocalcin, and significantly higher serum RANKL levels in patients with CAH than the healthy controls. This differences is more obvious in children with poor control and in those receiving prednisone therapy. Total bone mineral content (BMC [gm] have significant negative correlations to age (r = −0.81, P < 0.001, disease duration (r = −0.881, P < 0.001, 17 OH Progesterone level (r = −0.543, P < 0.05, RANKL level (r = −0.635, P < 0.05, and significant positive correlation with osteocalcin (r = 0.576, P < 0.001. Conclusions: Children from Upper Egypt with classic CAH may have reduced BMD and increase bone turnover compared with controls. This difference is more obvious in children with poor control and in those receiving prednisone therapy. Recommendations: Active monitoring of BMD in CAH children using Dual-energy X-ray absorptiometry (DEXA scanning. Furthermore, effort should be done to bring hydrocortisone to Upper Egypt to replace prednisone in children with classic congenital adrenal

    Two girls with central precocious puberty (CPP) associated with hypothalamic hamartoma (HH) and non classical form of congenital adrenal hyperplasia (NCAH), are reported. Case 1. The first patient, who showed at age around 4 years the onset of CPP, was submitted in view of some organic lesion to magnetic resonance (MRI) of the brain which documented the presence of HH. The remarkable acceleration of bone age (BA) advanced of 3 SD and some clinical signs of hyperandrogenism suggested the coexistence of NCAH, proved by adrenocorticotropic hormone (ACTH) test and molecular analysis. She resulted carrier of partial 21-hydroxylase deficiency. Case 2. In the second girl with CPP, aged 6.5 years, the remarkable advancement (4 SD) of bone age (BA) alerted to adrenal involvement. ACTH stimulation test and molecular analysis showed NACH due to 21-hydroxylase deficiency. Brain MRI, performed mainly for severe headache, showed the presence of HH. Yearly brain MRI to monitor HH dimensions and neurological examination with EEG, in order to exclude anomalies referable to gelastic epilepsy are advisable, in both cases. The authors' observation emphasizes the need to be careful in young patients with CPP, with fast progression of pubertal development and remarkable BA advancement. The association of CPP with HH and NCAH should be considered, performing not only MRI of the brain, but also ACTH test, beside LHRH test for the diagnosis of CPP. At the authors' knowledge this association has not been reported so far. Further observations are needed to understand if this rare combination is occasional or genetically determined.

    Full Text Available Background: There are recommendations regarding the total dose of hydrocortisone to be administered in the treatment of classical congenital adrenal hyperplasia (CAH to achieve the twin objectives of glucocorticoid replacement and control of hyperandrogenism. However, there is evidence gap regarding the breakup, timing and type of the steroid regimen. Objectives: Efficacy of three different glucocorticoid regimens having the same total dose of steroid, differing in either the timing or type of evening steroid administered, in achieving biochemical control of the disease was assessed. Materials and Methods: The study was done in 13 prepubertal children with classical CAH over a 6-month period with 2 months devoted to each regimen. We used a prospective cross-over design using 10-15 mg/m 2 total dose of hydrocortisone. Two-fifths of the total dose of hydrocortisone was administered in the morning and one-fifth of the total dose was administered at noon in all the regimens. The regimens differed in the timing of the evening dose of hydrocortisone, 06.00-07.00 pm in regimen 1 and 09.00-10.00 pm in regimen 2. The third regimen had the evening dose of hydrocortisone replaced by an equivalent dose of prednisolone suspension which was administered at 10.00 pm. Serum 17-hydroxyprogesterone and testosterone levels were compared to assess the efficacy of treatment regimens. Results: The three different regimens were found to be similar in their ability to control 17-hydroxyprogesterone and testosterone levels. The percentage of patients with predefined criteria for biochemically controlled disease was similar in all the three regimens. However, there was a trend toward better control of 17-hydroxyprogesterone levels in patients receiving evening dose of prednisolone. Conclusions: There is no significant advantage in administering the hydrocortisone dose late at night in patients with classical CAH.

    Labial adhesions (synechia vulvae) are a relatively common disorder of the external genitalia in prepubertal girls. They usually occur between 3 months and 6 years of age, with a peak between 13 and 23 months of life. In the majority of cases, labial adhesions are asymptomatic and noticed by the parents or a physician during a routine physical examination. Frequently, they cause recurrent urinary tract infections. This report presents the case of a 15-month-old girl with recurrent labial adhesions and urinary tract infections. She was followed-up by a urologist from the age of 3 months, treated topically (estriol cream 1 mg/g and emollients) and surgically. No signs of androgenization were seen apart from advanced bone age. Urinary steroid profile and molecular analysis confirmed the diagnosis of non-classic congenital adrenal hyperplasia (NCCAH) due to 21-hydroxylase deficiency. In the described case, a coincidence of NCCAH and labial adhesion cannot be excluded particularly in view of the resolving of urinary tract infections at the same time as resolving of labial adhesions. However, it seems that in cases of recurrent labial adhesion/synechia that require repeated surgical interventions in view of ineffectiveness of conservative treatment - as it was observed in the presented case - one should consider searching for NCCAH. This may allow not only for the causal treatment of labial adhesions but, above all, NCCAH and, in consequence, the prevention of intensification of virilization, hirsutism, menstrual cycle, and fertility disturbances that are observed starting from puberty.

    Full Text Available Myelolipomas are rare and benign neoplasms, predominant of the adrenal glands, consisting of adipose and mature hematopoietic tissue, commonly discovered incidentally with increased use of radiologic imaging. Few cases of giant bilateral adrenal masses are reported, especially in the setting of congenital adrenal hyperplasia (CAH. We report the case of a 39-year-old male with a history of CAH secondary to 21-α hydroxylase deficiency on steroids since childhood, self-discontinued during adolescence, presenting with abdominal distension, fatigue, decreased libido, and easy bruising. Imaging revealed giant bilateral adrenal masses. He subsequently underwent bilateral adrenalectomy found to be myelolipomas measuring 30 × 25 × 20 cm on the left and weighing 4.1 kg and 25 × 20 × 13 cm on the right and weighing 2.7 kg. Adrenal myelolipomas are found to coexist with many other conditions such as Cushing’s syndrome, Addison’s disease, and CAH. We discuss the association with high adrenocorticotropic hormone (ACTH states and review the studies involving ACTH as proponent leading to myelolipomas. Massive growth of these tumors, as in our case, can produce compression and hemorrhagic symptoms. We believe it is possible that self-discontinuation of steroids, in the setting of CAH, may have resulted in the growth of his adrenal masses.

    Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by enzyme defects in adrenal steroidogenic pathways. CAH due to 21-hydroxylase deficiency accounts for 95 % of cases. This case was diagnosed to have simple virilizing type of CAH and started on dexamethasone, and underwent genitoplasty and clitoroplasty at 25 years of age, then was married 3 years after surgery and conceived spontaneously 2 years after marriage, to deliver a healthy male baby. Thus, proper diagnosis and treatment with steroids and genitoplasty can give females with CAH a normal sexual, normal menstrual, and reproductive function.

    Full Text Available We report on a patient with genetically confirmed adrenal hypoplasia congenita (AHC whose presentation and laboratory abnormalities were consistent with the more common condition, congenital adrenal hyperplasia (CAH. The patient presented with failure to thrive and salt wasting. General appearance showed marked hyperpigmentation and normal male genitalia. He displayed mildly elevated 17-hydroxyprogesterone and markedly elevated 11-deoxycortisol levels at baseline and with ACTH stimulation testing. Results were consistent with 11β-hydroxylase deficiency. He required glucocorticoids and high doses of mineralocorticoids. The marked elevation in 11-deoxycortisol directed our clinical reasoning away from a hypoplastic condition and towards a hyperplasic adrenal condition. Sequencing of the DAX1 gene (named for dosage-sensitive sex reversal (DSS locus and the AHC locus on the X chromosome revealed a missense mutation. A review of the literature revealed that elevated 11-deoxycortisol levels have been noted in kindreds with DAX1 mutations, but only when measured very early in life. A mouse model has recently been described that displays elevated 11-deoxycorticosterone levels and evidence for hyperplasia of the zona glomerulosa of the adrenal gland. We conclude that DAX1 testing may be considered in patients with laboratory evidence of 11β-hydroxylase deficiency, especially in those with severe salt wasting.

    Full Text Available Lipoid congenital adrenal hyperplasia (lipoid CAH, a rare disorder of steroid biosynthesis, is the most severe form of CAH. In this disorder the synthesis of glucocorticoids, mineralocorticoids and sex steroids is impaired which result in adrenal failure, severe salt wasting crisis and hyperpigmentation in phenotypical female infants irrespective of genetic sex. In this report, we presented a 28-day-old phenotypic female infant, which referred with lethargy, failure to thrive and electrolyte abnormalities. Considering the clinical and biochemical findings, lipoid CAH was diagnosed and replacement therapy with standard doses of glucocorticoid and mineralocorticoid and sodium chloride was initiated. During follow-up, she had good clinical condition, but at 6 years of age, she refers with hypertension and adrenal insufficiency because of arbitrary drug discontinuation by mother. In ultrasonography an abdominal mass (the testicles was reported. Chromosome study showed 46XY pattern. Orchiectomy was performed. We recommended that in cases with clinical presentation of adrenal insufficiency if there is not the facility to determine the karyotype, repeated ultrasonography perform during follow-up. In addition, investigating the genetic bases of the disorder would help us to determine the pathogenesis of lipoid CAH in our community. It would be helpful in prenatal diagnosis and treatment of the disorder to prevent its related comorbidities.

    Congenital adrenal hyperplasia (CAH) describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge.

Data are presented indicating the applicability of this algorithm. Design: Retrospective case-control study involving FA-patients, and controls (C. Methods: FA-patients were classified into five groups, functional cutaneous androgenization (FCA: skin as well as functional androgenizing syndrome (FAS I (ovary, II (adrenal, III (multi-organ-disorder with FA, obesity, hyperinsulinaemia and IV (residual FA dysfunctions using group-specific variable clusters. They are set up by primary (classifying variables such as cutaneous androgenetic symptoms (acne vulgaris, hirsutism, androgenetic alopecia, body mass index (BMI, testosterone, free androgen index (FAI, polyfollicular ovaries (PFOs, and 1-h-insulin (after oral glucose loading. Groups FCA and FAS I–III were sub-classified through classic full-blown (“a” and non-classic, minimum standard core/miscellaneous clusters (“b”. Variables were allocated as integral part of different clusters (e.g. enhanced BMI: in FCAb, FAS IIb, FAS IIIa/b, and FAS IV. Patients’ complete characterization was achieved additionally by using secondary (facultative variables, e.g. triglycerid levels. Results: The FA-groups included 6, 33, 10, 59, and 18 subjects. All FCA-patients presented cutaneous androgenetic symptoms, PFOs were visualized in all FAS I and III patients. Group FAS Ia showed highest LH levels, and testosterone was higher in FAS I vs. FCA, FAS II, FAS IV and C. Levels of DHEAS were found to be highest in group FAS II. BMI and triglycerids were higher in FAS III vs. FCA, FAS I, FAS II, and C, and one-hr-insulin in FAS III was higher vs. FCA, FAS I, and C. In FAS IV covering the residual FA-patients, several obese, hyperinsulinaemic individuals were classified who showed an increased FAI without the presence of PFOs

    The congenital adrenal hyperplasias (CAH) are a group of genetic defects in cortisol biosynthesis, most commonly steroid 21-hydroxylase deficiency (21OHD). With the advent of cortisone therapy in the 1960s and newborn screening in the 1990s, most children with 21OHD now reach adulthood. The needs and concerns of adults with 21OHD overlap with those of children, but the focus and approach shift as these patients reach adulthood. Cohort studies suggest that adults with 21OHD experience significant health concerns such as infertility, obesity, short stature, neoplasia, and bone loss, as well as reduced quality of life. Nevertheless, the spectrum of health status and disease severity is broad, but only some of the reasons for these disparities are known. This review will summarize the current state of knowledge and suggested approaches to management adults with classic 21OHD, plus a few major considerations for adults with nonclassic 21OHD.

    Congenital adrenal hyperplasia (CAH) is a family of autosomal recessive disorders caused by mutations in genes encoding the enzymes involved in one of the 5 steps of adrenal steroid synthesis or the electron donor P450 oxidoreductase (POR) enzyme. Steroid 21-hydroxylase deficiency (21-OHD), the principal focus of this review, accounts for about 90-95% of all CAH cases, and its biochemical and clinical severity depends on the underlying CYP21A2 gene disruption. Molecular genetic advancements have been achieved in recent years, and the aim of this review is to attempt to highlight its contribution to the comprehension and management of the disease. When possible, we will try to achieve this goal also by providing some results from our personal experience regarding: some aspects of CYP21A2 gene analysis, with basic genotype/phenotype relationships; its crucial role in both genetic counselling and in prenatal diagnosis and treatment in families at risk for 21-OHD; its help in the comprehension of the severity of the disease in patients diagnosed by neonatal screening and possibly treated before an evident salt-loss crisis or before performing adequate blood sampling; its usefulness in the definition of post ACTH 17-hydroxyprogesterone values, discriminating between non-classic, heterozygote and normal subjects; and finally the contribution of genes other than CYP21A2 whose function or dysfunction could influence 21-hydroxylase activity and modify the presentation or management of the disease.

    While testicular adrenal rest tumor is generally a rare intratesticular tumor, it is frequent in patients with congenital adrenal hyperplasia. The tumors are diagnosed and followed up by ultrasound examination because these tumors are non-palpable and symptomless in most cases and always benign. Ultrasound imaging features change depending on how congenital adrenal hyperplasia is controlled. We herein report three cases of testicular adrenal rest tumors with different usual and unusual imaging findings and follow-up imaging. Patient 1 was a 14-year-old boy who presented with poor compliance to medication. Patient 2 and 3 were a 10-year-old and 13-year-old boy who presented with precocious puberty and short stature, respectively. Ultrasound examinations demonstrated oval hypoechoic masses and irregular speculated hyperechoic masses in the testes and different serial imaging findings.

    To assess whether exposure to excessive adrenal androgens increases muscle strength in girls with congenital adrenal hyperplasia, eighteen girls with 21 hydroxylase type congenital adrenal hyperplasia (CAH), aged 4.3-12.1 years were studied and compared with 78 healthy control girls aged 4-16 years. Maximum voluntary isometric strength was measured using a muscle testing chair, and the highest value from at least three attempts with each leg was recorded. Height and weight were also measured in the patients and controls. When compared with normal girls of similar age, some of the girls with CAH seemed unusually strong, but this difference was less marked when the CAH girls were compared with controls of similar weights. However, our data suggest that girls diagnosed later in childhood may have unusual muscle strength.

    Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, management, and follow-up of the patients, although recommendations according to most guidelines are weak when present. Thus, the authors aimed to conduct a narrative synthesis of how imaging can help in the management of patients with CAH, especially focused on genitography, ultrasonography, computed tomography, and magnetic resonance imaging.

    Chronic glucocorticoid therapy is associated with reduced bone mineral density. In paediatric patients with congenital adrenal hyperplasia, increased levels of androgens could not only counteract this effect, but could also advance bone age, with interference in the evaluation of densitometry. We evaluate bone mineral density in paediatric patients with classic congenital adrenal hyperplasia taking into account chronological and bone ages at the time of the measurement. Patients aged between 5 and 19 years underwent radiography of the hand and wrist followed by total body and lumbar spine densitometry. Chronological and bone ages were used in the scans interpretation. In fourteen patients, mean bone mineral density Z-score of total body to bone age was -0.76 and of lumbar spine to bone age was -0.26, lower than those related to chronological age (+0.03 and +0.62, resp.). Mean Z-score differences were statistically significant (P = 0.004 for total body and P = 0.003 for lumbar spine). One patient was classified as having low bone mineral density only when assessed by bone age. We conclude that there was a reduction in the bone mineral density Z-score in classic congenital adrenal hyperplasia paediatric patients when bone age was taken into account instead of chronological age.

    Congenital adrenal hyperplasia (CAH) is characterized by decreased adrenal hormone production due to enzymatic defects and subsequent rise of adrenocorticotrophic hormone that stimulates the adrenal cortex to become hyperplastic, and sometimes tumorous. As the pathophysiology is basically a defect in the biosynthesis of cortisol, one may not consider CAH in patients with hypercortisolism. We report a case of a 41-yr-old man with a 4 cm-sized left adrenal tumorous lesion mimicking Cushing's syndrome who was diagnosed with CAH. He had central obesity and acanthosis nigricans involving the axillae together with elevated 24-hr urine cortisol level, supporting the diagnosis of Cushing's syndrome. However, the 24-hr urine cortisol was suppressed by 95% with the low dose dexamethasone suppression test. CAH was suspected based on the history of precocious puberty, short stature and a profound suppression of cortisol production by dexamethasone. CAH was confirmed by a remarkably increased level of serum 17-hydroxyprogesterone level. Gene mutation analysis revealed a compound heterozygote mutation of CYP21A2 (I173N and R357W). PMID:23166432

    Congenital adrenal hyperplasia (CAH) is caused by a deficiency in an adrenal enzyme resulting in alterations in cortisol and aldosterone production. Bone status is affected by chronic glucocorticoid therapy and excess androgen exposure in children with CAH. This cross-sectional study enrolled participants with 21-hydroxylase deficiency from a pediatric referral center. Bone mineral density in the participants was normal when compared to age, gender and ethnicity adjusted standards, with respect to chronological age or bone age. Lean body mass was positively correlated with bone mineral content (BMC), independent of fat mass (p bone status may be explained by the differential effects of glucocorticoids on growing bone, beneficial androgen effects, or other disease specific factors.

    Congenital adrenal hyperplasia (CAH) is one of the most common inherited autosomal recessive disorders, caused by deficiency of one of the enzymes involved in steroid synthesis. The clinical picture of the most prevalent form, i.e. 21-hydroxylase deficiency, is characterized by cortisol and mostly aldosterone deficiency and androgen excess (leading to congenital virilization in girls). Treatment consists of glucocorticoids, aimed at substitution of cortisol deficiency and, decrease of androgen excess. Usually supraphysiological doses of glucocorticoids are required to effectively suppress adrenal androgens. Furthermore, with the currently available glucocorticoid preparations, it is not possible to simulate a normal circadian rhythm in CAH patients. Therefore, it is a difficult task for (pediatric) endocrinologists to find the best balance between under- and overtreatment thereby avoiding important long term complications. In this review we will discuss the current pharmacologic treatment options. We give age dependent dose recommendations and describe the limitations of current treatment strategies. We discuss effects on fertility, bone density and cardiovascular risks. Recommendations about the use of glucocorticoids in case of fever or stress situations are given. The principles of treatment of non classic (mild) CAH are discussed in a separate section. Also prenatal therapy, to prevent congenital virilization of a female CAH newborn, is discussed. Furthermore, an overview of alternative pharmacological treatment options in the future is given.

    Nonclassical congenital adrenal hyperplasia (NCCAH) caused by 21-hydroxylase deficiency is a common autosomal recessive condition that can present with a wide range of hyperandrogenemic signs in childhood or adulthood. The management of children with NCCAH can be challenging, as no universally accepted guidelines have been established. Our goal was to evaluate the literature and develop an evidence-based guideline for the medical management of children and adolescents with NCCAH. We reviewed the published literature and used the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) system when appropriate to grade the evidence and provide recommendations for the medical management of children and adolescents with NCCAH, appropriate transition practices from pediatric to adult endocrine care, and psychological issues that should be addressed in parents and patients with NCCAH. We offer recommendations, based on the available evidence, for the management of NCCAH at the different developmental stages from diagnosis through transition to adulthood.

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a disorder characterized by impaired cortisol synthesis leading to excessive production of adrenal androgens. Prenatal and postnatal exposure to excess androgens may increase neural vulnerability to insult and affect cognitive functions, particularly dopamine-dependent neural circuits responsible for executive functioning (EF). Our study aimed to investigate relationship between more pronounced androgen exposure and EF-related behaviors in children with CAH, as well as sex differences in these associations. Parents of patients with CAH (n=41, boys=17, girls=24; age: M=8.41, SD=4.43) completed the Behavior Rating Inventory of Executive Function (BRIEF), a measure assessing behavioral manifestations of EF. Assessments of bone age advancement, a proxy of cumulative androgen exposure, were analyzed. Advanced bone age predicted more inhibition difficulties in boys but not in girls, and more difficulties in all other BRIEF domains in the total sample. Excessive androgen production affected EF such that more advanced bone age led to more EF-related difficulties. Sex differences in inhibition may result from estrogen exposure moderating the impact of androgens in girls but not in boys. Future interventions may include targeting EF in patients with CAH to enhance quality of life and reduce cognitive consequences associated with this disease.

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive hereditary diseases. The impairment of cortisol synthesis leads to excessive stimulation of the adrenal glands by adrenocorticotropic hormone (ACTH), adrenal hyperplasia, and excessive androgen synthesis. The syndrome is characterised by a considerable correlation between the genotype and the phenotype with the type of CYP21A2 gene mutation affecting the severity of 21-hydroxylase deficiency. The clinical manifestations of CAH in adults result from adrenocortical and adrenomedullary insufficiency, hyperandrogenism, and the adverse effects of glucocorticosteroids used for the treatment of the condition. Non-classic CAH may sometimes be asymptomatic. In patients with classic CAH obesity, hyperinsulinaemia, insulin resistance, and hyperleptinaemia are more often seen than in the general population. These abnormalities promote the development of metabolic syndrome and its sequelae, including endothelial dysfunction, and cardiovascular disease. Long-term glucocorticosteroid treatment is also a known risk factor for osteoporosis. Patients with CAH require constant monitoring of biochemical parameters (17a-hydroxyprogesterone [17-OHP] and androstenedione), clinical parameters (body mass, waist circumference, blood pressure, glucose, and lipids), and bone mineral density by densitometry. The principal goal of treatment in adults with CAH is to improve quality of life, ensure that they remain fertile, reduce the manifestations of hyperandrogenisation in females, and minimise the adverse effects of glucocorticosteroid treatment. Patients with classic CAH require treatment with glucocorticosteroids and, in cases of salt wasting, also with a mineralocorticosteroid. Radical measures, such as bilateral adrenalectomy, are very rarely needed. Asymptomatic patients with non-classic CAH require monitoring: treatment is not always necessary. Medical care for patients

    During childhood, the main aims of the medical treatment of congenital adrenal hyperplasia (CAH) secondary to 21-hydroxylase deficiency, are to prevent salt loss and virilization and to achieve normal stature and normal puberty. As such, there is a narrow therapeutic window through which the intended results can be achieved. In adulthood, the clinical management has received little attention, but recent studies have shown the relevance of long-term follow-up of these patients. Indeed, long-term evaluation of adult CAH patients enables the identification of multiple clinical, hormonal and metabolic abnormalities as bone mineral density alteration, overweight and disturbed reproductive functions. In women with classic CAH, low fertility rate is reported, and is probably the consequence of multiple factors, including neuroendocrine and hormonal factors, feminizing surgery, and psychological factors. Men with CAH may present hypogonadism either through the effect of adrenal rests or from suppression of gonadotropins resulting in infertility. These patients should therefore be carefully followed-up, from childhood through to adulthood, to avoid these complications and to ensure treatment compliance and tight control of the adrenal androgens, by multidisciplinary teams who have knowledge of CAH.

    The primary treatment for patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is glucocorticoid replacement therapy, which at supraphysiologic levels can result in diminished bone accrual and lead to osteopenia and osteoporosis. Unlike other diseases treated with chronic glucocorticoid therapy, previous studies of patients with 21OHD have not demonstrated a detrimental effect of glucocorticoid treatment on bone mineral density (BMD). It has been postulated that the elevated androgens typically found in these patients have a protective effect on bone integrity, but the precise mechanism remains unknown. We propose that the inhibitory effect of corticosteroid therapy on bone formation is counteracted by estrogen's effect on bone resorption through the RANK-L/osteoprotegerin (OPG) system. A better understanding of the mechanism by which patients with 21OHD are protected against bone loss may lead to novel therapeutic measures to prevent or treat osteopenia and osteoporosis in other conditions, including postmenopausal women.

    Giovanni Scala Marchini

    Full Text Available CONTEXT: Synthesis of cortisol and aldosterone is impaired in patients with congenital adrenal hyperplasia (CAH because of 21-hydroxylase deficiency. Men with CAH have low fertility rates compared with the normal population, and this is related to testicular adrenal rest tumors. Findings of azoospermia in combination with a testicular tumor on ultrasound are likely to have a mechanical cause, especially when in the testicular mediastinum. The preferred treatment method consists of intensive corticoid therapy. However, when the tumor is unresponsive to steroid therapy, surgical treatment should be considered. CASE REPORT: We present the case of a male patient with CAH due to 21-hydroxylase deficiency who presented a testicular tumor and azoospermia. Treatment with low daily corticoid doses had previously been started by an endocrinologist, but after 12 months, no significant change in sperm count was found. Although the adrenocorticotrophic hormone and 17-hydroxyprogesterone levels returned to normal values, the follicle-stimulating hormone (FSH, luteinizing hormone and testosterone levels remained unchanged. Ultrasound examination confirmed that the testicles were small and heterogenous bilaterally, and revealed a mosaic area at the projection of the testis network bilaterally. Magnetic resonance imaging confirmed the finding. Testicular biopsy revealed the presence of preserved spermatogenesis and spermiogenesis in 20% of the seminiferous tubules in the right testicle. The patient underwent testis-sparing tumor resection. After 12 months of follow-up, there was no tumor recurrence but the patient still presented azoospermia and joined an intracytoplasmic sperm injection program.

    Full Text Available We present a patient with nonclassic congenital adrenal hyperplasia (NCAH misdiagnosed as mosaic Turner syndrome. She presented with complaints of primary infertility. Short stature, the presence of facial hair and hoarse voice was also noted. She had primary amenorrhea and was advised for karyotype at 16 years of age, which was reported as 45, X[20]/46, XX[80], stating her as a case of mosaic Turner syndrome. Clitoroplasty was done at 21 years of age for clitoromegaly, which was noticed during puberty. The diagnosis of mosaic Turner could not explain the virilization. Therefore, we repeated the karyotype, which revealed 46, XX in more than 100 metaphases and was sufficient to exclude mosaicism. Furthermore, the endocrinological evaluation revealed high testosterone level with a normal 17 alpha-hydroxyprogesterone (17-OHP. The presence of pubertal onset virilization with a karyotype of 46, XX and raised testosterone level with normal 17-OHP level, raised the suspicion of NCAH for which adrenocorticotropic hormone stimulation test was done which confirmed the diagnosis of NCAH.

    2016-06-01

    Congenital adrenal hyperplasia (CAH) refers to a group of recessively inherited disorders of cortisol production, which in the classical form results in virilisation of female fetuses. Since the 1980s, antenatal treatment with dexamethasone has been recommended in high-risk pregnancies to minimise the risk of virilising the female genitalia of affected fetuses. To be effective, this treatment requires implementation in early pregnancy, prior to the commencement of autonomous fetal adrenal androgen synthesis. Using this approach, seven of eight high-risk pregnancies are treated unnecessarily, prior to establishing the fetal gender or the confirmed diagnosis of a genetically affected pregnancy. In the face of ongoing concerns regarding potential adverse maternal-fetal effects of antenatal dexamethasone exposure, a review of this practice has been advocated by expert advisory groups. In this review, we summarise current controversies, potential improvements and future directions in the management of pregnancies at risk of CAH. In high-risk families, recent genomic advances include early prenatal diagnosis utilising noninvasive genetic techniques to minimise unnecessary dexamethasone exposure to unaffected fetuses. In affected pregnancies when families elect for antenatal treatment, optimal antenatal dosing regimens need to be defined and a standardised treatment and follow-up protocol are recommended. Establishment of a national registry with standardised follow-up will allow future families to be better informed of the risks and benefits of both treated and untreated fetal CAH.

    Congenital adrenal insufficiency is caused by specific genetic mutations. Early suspicion and definite diagnosis are crucial because the disease can precipitate a life-threatening hypovolemic shock without prompt treatment. This study was designed to understand the clinical manifestations including growth patterns and to find the usefulness of ACTH stimulation test. Sixteen patients with confirmed genotyping were subdivided into three groups according to the genetic study results: congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH, n=11), congenital lipoid adrenal hyperplasia (n=3) and X-linked adrenal hypoplasia congenita (n=2). Bone age advancement was prominent in patients with CAH especially after 60 months of chronologic age (n=6, 67%). They were diagnosed in older ages in group with bone age advancement (Pcongenital adrenal insufficiency. ACTH stimulation test played an important role to support the diagnosis and serum 17-hydroxyprogesterone levels were significantly elevated in all of the CAH patients. The test will be important for monitoring growth and puberty during follow up of patients with congenital adrenal insufficiency.

  6. Recommendations for treatment of nonclassic congenital adrenal hyperplasia (NCCAH): an update.

    Trapp, Christine M; Oberfield, Sharon E

    2012-03-10

    Congenital adrenal hyperplasia (CAH) is a family of autosomal recessive disorders. 21-Hydroxylase deficiency, in which there are mutations in CYP21A2 (the gene encoding the adrenal 21-hydroxylase enzyme), is the most common form (90%) of CAH. In classic CAH there is impaired cortisol production with diagnostic increased levels of 17-OH progesterone. Excess androgen production results in virilization and in the newborn female may cause development of ambiguous external genitalia. Three-fourths of patients with classic CAH also have aldosterone insufficiency, which can result in salt-wasting; in infancy this manifests as shock, hyponatremia and hyperkalemia. CAH has a reported incidence of 1:10,000-1:20,000 births although there is an increased prevalence in certain ethnic groups. Nonclassic CAH (NCCAH) is a less severe form of the disorder, in which there is 20-50% of 21-hydroxylase enzyme activity (vs. 0-5% in classic CAH) and no salt wasting. The degree of symptoms related to androgen excess is variable and may be progressive with age, although some individuals are asymptomatic. NCCAH has an incidence of 1:1000-1:2000 births (0.1-0.2% prevalence) in the White population; an even higher prevalence is noted in certain ethnic groups such as Ashkenazi Jews (1-2%). As many as two-thirds of persons with NCCAH are compound heterozygotes and carry a severe and mild mutation on different alleles. This paper discusses the genetics of NCCAH, along with its variable phenotypic expression, and reviews the clinical course in untreated patients, which includes rapid early childhood growth, advanced skeletal age, premature adrenarche, acne, impaired reproductive function in both sexes and hirsutism as well as menstrual disorders in females. Finally, it addresses treatment with glucocorticoids vs. non treatment and other therapies, particularly with respect to long term issues such as adult metabolic disease including insulin resistance, cardiovascular disease, metabolic syndrome

We examined doses used, control of adrenal androgen secretion, and growth and skeletal maturation of 8 children with CAH treated with dexamethasone beginning in infancy. Results. 3 boys and 5 girls with classical CAH (17-hydroxyprogesterone at diagnosis >20,000 ng/dL were treated with dexamethasone beginning at diagnosis (<10 days of age. Patients were also treated with fludrocortisone and sodium chloride. The average initial medication dose was 0.1 mg (0.28±0.015 mg/m2; all doses were given in the morning using a dosing syringe to administer a 0.1 mg/mL elixir. The children were treated for 6.5±2.0 years over which time the change in bone age to chronological age ratio (ΔBA/ΔCA was 0.9±0.06. Most recent height Z' scores were +0.5±0.2, and body mass index (BMI scores were 18±0.2.

    Prenatal-onset classical congenital adrenal hyperplasia (CAH) in 46,XX individuals is associated with variable masculinization/defeminization of the genitalia and of behavior, presumably both due to excess prenatal androgen production. The purpose of the current study was threefold: (1) to extend the gender-behavioral investigation to the mildest subtype of 46,XX CAH, the non-classical (NC) variant, (2) to replicate previous findings on moderate and severe variants of 46,XX CAH using a battery of diversely constructed assessment instruments, and (3) to evaluate the utility of the chosen assessment instruments for this area of work. We studied 63 women with classical CAH (42 with the salt wasting [SW] and 21 with the simple virilizing [SV] variant), 82 women with the NC variant, and 24 related non-CAH sisters and female cousins as controls (COS). NC women showed a few signs of gender shifts in the expected direction, SV women were intermediate, and SW women most severely affected. In terms of gender identity, two SW women were gender-dysphoric, and a third had changed to male in adulthood. All others identified as women. We conclude that behavioral masculinization/defeminization is pronounced in SW-CAH women, slight but still clearly demonstrable in SV women, and probable, but still in need of replication in NC women. There continues a need for improved instruments for gender assessment.

    Full Text Available Abstract Introduction X-linked congenital adrenal hypoplasia is a rare developmental disorder of the human adrenal cortex and is caused by deletion or mutation of the dosage-sensitive sex reversal adrenal hypoplasia congenita critical region of the X chromosome, gene 1 (DAX-1 gene. Most affected children present with failure to thrive, salt wasting and hypoglycemic convulsions in the first months of life. Hypospadias affects approximately one in 250 live male births. Mutations in the mastermind-like domain-containing 1 (MAMLD1 gene have been implicated as one of the causes of hypospadias in children. To the best of our knowledge, an association between congenital adrenal hypoplasia due to a DAX-1 mutation and hypospadias due to mutation of the MAMLD1 gene has not previously been reported in the literature. Case presentation A 35-day-old male Egyptian baby was referred to our institution for the evaluation of a two-week history of recurrent vomiting associated with electrolyte imbalance. On examination, our patient was found to have hypotension and dehydration. A genital examination showed distal penile hypospadias with chordee and normal testes. He had hyponatremia, hyperkalemia, hypoglycemia and metabolic acidosis. Endocrinological investigations revealed low levels of cortisol, 17-hydroxyprogesterone and aldosterone, with a high level of adrenocorticotrophic hormone. A provisional diagnosis of congenital adrenal hypoplasia associated with hypospadias was made. A molecular genetics study confirmed the diagnosis of X-linked congenital adrenal hypoplasia due to DAX-1 mutations and hypospadias due to MAMLD1 mutation. He was started on hydrocortisone and fludrocortisone treatment. After three weeks of treatment, his symptoms improved and his blood sugar, sodium, potassium and cortisol levels normalized. Conclusions We report the case of an Egyptian baby with an association of congenital adrenal hypoplasia due to DAX-1 mutation and hypospadias due

Especially infants with CAH have a higher seizure risk as a consequence of hyponatremia and hypoglycemia. Typical trigger situations for adrenal crisis are infectious diseases, especially gastroenteritis. Patients with CAH and their family members should be educated in terms of compliance with glucocorticoid medication, adequate stress dosing (usually triple to five fold elevated oral hydrocortisone dosage and intramuscular injection of hydrocortisone or prednisone. p bKurzfassung: /bPatienten mit klassischem adrenogenitalem Syndrom (AGS sind lebenslang für potentiell letale Nebennierenkrisen gefährdet.

    Women with congenital adrenal hyperplasia (CAH) (N = 31) and their unaffected sisters or female cousins (N = 15) participated in a study of psychosexual development. All participants were > or = 18 years of age (mean age, 25 years; range, 18-40). Comparisons were also made between the CAH women with the salt-wasting (SW) form of the disorder and those with simple virilization (SV). A psychosexual assessment protocol examined six variables: (1) sex assignment at birth (probands only); (2) recalled sex-typed behavior during childhood; (3) gender identity and gender role identification in adulthood; (4) relationship status; (5) sexual orientation in fantasy; and (6) sexual orientation in behavior. Salt-wasting status and sex assignment at birth were also ascertained for the CAH women who either refused to participate in the study (N = 10) or could not be traced (N = 13). Compared to the controls, the women with CAH recalled more cross-gender role behavior and less comfort with their sense of "femininity" during childhood. The two groups did not differ in degree of gender dysphoria in adulthood, although the probands showed more cross-gender role identification. Three of the nonparticipant probands were living, as adults, in the male social role (2 reared from birth as boys and 1 who changed from the female to the male social role during adolescence). The CAH women and the controls did not differ in relationship status (married/cohabiting vs. single). The CAH women had lower rates of exclusive heterosexual fantasy and fewer sexual experiences with men than the controls; however, the CAH women did not have more sexual experiences with women than the controls. Comparisons between the SW and SV revealed several differences: the SW were less likely to be assigned to the female sex at birth, recalled more cross-gender role behavior during childhood, were less likely to be married or cohabiting, and had lower rates of sexual experiences with men. The results were discussed

    Full Text Available Congenital adrenal hyperplasia (CAH is characterized by adrenal steroid biosynthesis defect. Steroid replacement therapy should be performed regularly in these patients. Adrenal crisis may be present in acute stress due to increased cortisol requirements or in steroid deficiency due to stopping steroid medication abruptly. In patients with acute adrenal insufficiency, severe hypotension or hypovolemic shock occurs typically. Acute encephalopathy can be seen due to hypoxia, hypervolemia, or hypoglycemia. Diffusion restriction can be seen in cortical-subcortical regions of frontal and parieto-occipital lobes and in splenium of corpus callosum. In CAH patients with neurologic symptoms, Diffusion weighted images (DWI is very important in the diagnosis and follow-up of acute encephalopathy.

    Congenital adrenal hyperplasia (CAH) describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Treatment of the classic or severe form of CAH is targeted at replacing cortisol and aldosterone and effectively controlling excess androgen symptoms by using the lowest possible glucocorticoid dose. Treatment of the mild or nonclassic form is targeted at controlling excess androgen symptoms and may or may not involve glucocorticoid therapy. Hydrocortisone is the treatment of choice for children, but there is no consensus on how patients should be treated as adults. Current glucocorticoid therapy is suboptimal because it is often difficult to reduce excess androgen without giving excess glucocorticoid, and patients may experience hypercortisolism, androgen excess, or a combination of these states. Treatment of CAH, especially in the adult patient, remains controversial given the lack of prospective randomized controlled trials comparing treatment regimens. Nevertheless, patients benefit from careful individualized therapy with avoidance of Cushingoid side effects and optimization of reproductive, sexual, and bone health.

    The primary goal of newborn mass screening (MS) for congenital adrenal hyperplasia (CAH) is the prevention of life-threatening salt-wasting crisis in the most severe forms of CAH, and MS for CAH has been implemented in several countries. We summarize here our experience and results from newborn CAH MS from 1982 to 2010 in Sapporo City. During these 28 yr, the level of 17-hydroxyprogesterone (17-OHP) was determined in MS of samples from 498,147 newborns. During this period, 26 individuals (19 females and 7 males) with 21-hydroxylase deficiency (21-OHD) were detected. Of the 26 CAH, 20 were classified as having the salt-wasting (SW) form, 4 were classified as having the simple virilizing (SV) form, and 2 were classified as having the noncalssic (NC) form. Therefore, the frequency of the classical type of CAH was 1 in 20,756. In order to improve the effectiveness, we employed high-performance liquid chromatography (HPLC) as a second tier test from 2000. During this period, among the recalled babies, 75.4% were born prior to the 37th wk of gestation age, and the recall rate was 5.38% for premature neonates and 0.06% for mature neonates. MS for CAH in Sapporo is effective for the identification of the SW and SV forms of 21-OHD. However, the recall rate of premature babies is still high after the introduction of HPLC as a second tier test.

    A combination of Turner syndrome (TS) and classical congenital adrenal hyperplasia (CAH) is rare. A one-day-old newborn was referred to our hospital with ambiguous genitalia. The parents were third-degree relatives. The infant’s weight was 3350g (50-75p), and the head circumference was 34.5cm (50p). The gonads were nonpalpable. Presence of a 3 cm phallus, one urogenital opening into the perineum, and incomplete labial fusion were identified. Laboratory tests revealed a classical type of CAH due to 21-hydroxylase deficiency. Karyotyping revealed a 45X0(35)/46XX(22) pattern with negative sex-determining region Y (SRY) on gene analysis. At the most recent follow-up visit, the patient appeared to be in good health - her height was 70.4 cm [-1.5 standard deviation (SD)] and her weight was 9.8 kg (0.3 SD). She was receiving hydrocortisone in a dose of 10 mg/m2/day, fludrocortisone acetate in a dose of 0.075 mg/day, and oral salt of 1 g/day. System examinations were normal. The patient’s electrolyte levels were found to be normal and she was in good metabolic control. The findings of this patient demonstrate that routine karyotyping during investigation of patients with sexual differentiation disorders can reveal TS. Additionally, signs of virilism should always be investigated at diagnosis or during physical examinations for follow-up of TS cases. [i][/i]SRY analysis should be performed primarily when signs of virilism are observed. CAH should also be considered in patients with negative [i]SRY[/i]. Conflict of interest:None declared.

    The hypothalamic-pituitary-adrenal (HPA) axis is a classic neuroendocrine system. One of the best ways to understand the HPA axis is to appreciate its dynamics in the variety of diseases and syndromes that affect it. Excess glucocorticoid activity can be due to endogenous cortisol overproduction (spontaneous Cushing’s syndrome) or exogenous glucocorticoid therapy (iatrogenic Cushing’s syndrome). Endogenous Cushing’s syndrome can be subdivided into ACTH-dependent and ACTH-independent, the latt...

    Background: In congenital adrenal hyperplasia (CAH) with ambiguous genitalia, assigning gender of rearing can be complex, especially If genitalia is highly virilized. Apart from karyotype, prenatal androgen exposure, patient's gender orientation, sociocultural, and parental influences play a role.

    Context: Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition that arises from mutations in CYP21A2 gene, which encodes for the steroidogenic enzyme 21-hydroxylase. To prevent genital ambiguity in affected female fetuses, prenatal treatment with dexamethasone must begin on or before gestational week 9. Currently used chorionic villus sampling and amniocentesis provide genetic results at approximately 14 weeks of gestation at the earliest. This means that mothers who want to undergo prenatal dexamethasone treatment will be unnecessarily treating seven of eight fetuses (males and three of four unaffected females), emphasizing the desirability of earlier genetic diagnosis in utero. Objective: The objective of the study was to develop a noninvasive method for early prenatal diagnosis of fetuses at risk for CAH. Patients: Fourteen families, each with a proband affected by phenotypically classical CAH, were recruited. Design: Cell-free fetal DNA was obtained from 3.6 mL of maternal plasma. Using hybridization probes designed to capture a 6-Mb region flanking CYP21A2, targeted massively parallel sequencing (MPS) was performed to analyze genomic DNA samples from parents and proband to determine parental haplotypes. Plasma DNA from pregnant mothers also underwent targeted MPS to deduce fetal inheritance of parental haplotypes. Results: In all 14 families, the fetal CAH status was correctly deduced by targeted MPS of DNA in maternal plasma, as early as 5 weeks 6 days of gestation. Conclusions: MPS on 3.6 mL plasma from pregnant mothers could potentially provide the diagnosis of CAH, noninvasively, before the ninth week of gestation. Only affected female fetuses will thus be treated. Our strategy represents a generic approach for noninvasive prenatal testing for an array of autosomal recessive disorders. PMID:24606108

  11. Splicing mutation in CYP21 associated with delayed presentation of salt-wasting congenital adrenal hyperplasia

    Patients with salt-wasting congenital adrenal hyperplasia (SW-CAH) most commonly carry an A-G transition at nucleotide 656 (nt 656 A{r_arrow}G), causing abnormal splicing of exons 2 and 3 in CYP21, the gene encoding active steroid 21-hydroxylase. Affected infants are severely deficient in cortisol and aldosterone, and usually come to medical attention during the neonatal period. We report on 2 affected boys, homozygous for the nt 656 mutation, who thrived in early infancy, but suffered salt-wasting crises unusually late in infancy, at 3.5 and 5.5 months, respectively. Laboratory studies at presentation showed hyponatremia, hyperkalemia, dehydration, and acidosis; serum aldosterone was low in spite of markedly elevated plasma renin activity. Basal 17-hydroxyprogesterone levels were only moderately elevated, yet the stimulated levels were more typical of severe, classic CAH due to 21-hydroxylase deficiency. Genomic DNA from the patients was analyzed. Southern blot showed no major deletions or rearrangements. CYP21-specific amplification by polymerase chain reaction, coupled with allele-specific hybridization using wild-type and mutant probes at each of 9 sites for recognized disease-causing mutations, revealed a single, homozygous mutation in each patient: nt 656 A{r_arrow}G. These results were confirmed by sequence analysis. We conclude that the common nt 656 A{r_arrow}G mutation is sometimes associated with delayed phenotypic expression of SW-CAH. We speculate that variable splicing of the mutant CYP21 may modify the clinical manifestation of this disease. 22 refs., 1 fig., 1 tab.

    Congenital adrenal hyperplasia (CAH) is one of the most common autosomal recessive inherited endocrine disease. Steroid 11β-hydroxylase deficiency (11β-OHD) is the second most common form of CAH. The aim of the study was to study the functional consequences of three novel and one previously described CYP11B1 gene mutations (p.(Arg143Trp), p.(Ala306Val), p.(Glu310Lys) and p.(Arg332Gln)) detected in patients suffering from classical and non-classical 11β-OHD. Functional analyses were performed by using a HEK293 cell in vitro expression system comparing wild type (WT) with mutant 11β-hydroxylase activity. Mutant proteins were examined in silico to study their effect on the three-dimensional structure of the protein. Two mutations (p.(Ala306Val) and p.(Glu310Lys)) detected in patients with classical 11β-OHD showed a nearly complete loss of 11β-hydroxylase activity. The mutations p.(Arg143Trp) and p.(Arg332Gln) detected in patients with non-classical 11β-OHD showed a partial functional impairment with approximately 8% and 6% of WT activity, respectively. Functional mutation analysis allows the classification of novel CYP11B1 mutations as causes of classical and non-classical 11β-OHD. The detection of patients with non-classical phenotypes underscores the importance to screen patients with a phenotype comparable to non-classical 21-hydroxylase deficiency for mutations in the CYP11B1 gene in case of a negative analysis of the CYP21A2 gene. As CYP11B1 mutations are most often individual for a family, the in vitro analysis of novel mutations is essential for clinical and genetic counselling. PMID:24022297

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is caused by the autosomal recessive inheritance of mutations in the gene CYP21A2. CYP21A2 mutations lead to variable impairment of the 21-hydroxylase enzyme, which, in turn, is associated with three clinical phenotypes, namely, salt wasting, simple virilizing, and non-classical CAH. However, it is known that a given mutation can associate with different clinical phenotypes, resulting in a high rate of genotype–phenotype non-concordance. We aimed to study the genotype–phenotype non-concordance in a family with three sibs affected with non-classical CAH. All had hormonal evidence of non-classical CAH, but this phenotype could not be explained by the genotype obtained from commercial CYP21A2 genetic testing, which revealed heterozygosity for the maternal 30 kb deletion mutation. We performed Sanger sequencing of the entire CYP21A2 gene in this family to search for a rare mutation that was not covered by commercial testing and found in the three sibs a second, rare c.1097G>A (p.R366H) mutation in exon 8. Computational modeling confirmed that this was a mild mutation consistent with non-classical CAH. We recommend that sequencing of entire genes for rare mutations should be carried out when genotype–phenotype non-concordance is observed in patients with autosomal recessive monogenic disorders, including CAH.

    Full Text Available CONTEXT: Steroidogenic acute regulatory protein (StAR is crucial for transport of cholesterol to mitochondria where biosynthesis of steroids is initiated. Loss of StAR function causes lipoid congenital adrenal hyperplasia (LCAH. OBJECTIVE: StAR gene mutations causing partial loss of function manifest atypical and may be mistaken as familial glucocorticoid deficiency. Only a few mutations have been reported. DESIGN: To report clinical, biochemical, genetic, protein structure and functional data on two novel StAR mutations, and to compare them with published literature. SETTING: Collaboration between the University Children's Hospital Bern, Switzerland, and the CIBERER, Hospital Vall d'Hebron, Autonomous University, Barcelona, Spain. PATIENTS: Two subjects of a non-consanguineous Caucasian family were studied. The 46,XX phenotypic normal female was diagnosed with adrenal insufficiency at the age of 10 months, had normal pubertal development and still has no signs of hypergonodatropic hypogonadism at 32 years of age. Her 46,XY brother was born with normal male external genitalia and was diagnosed with adrenal insufficiency at 14 months. Puberty was normal and no signs of hypergonadotropic hypogonadism are present at 29 years of age. RESULTS: StAR gene analysis revealed two novel compound heterozygote mutations T44HfsX3 and G221S. T44HfsX3 is a loss-of-function StAR mutation. G221S retains partial activity (∼30% and is therefore responsible for a milder, non-classic phenotype. G221S is located in the cholesterol binding pocket and seems to alter binding/release of cholesterol. CONCLUSIONS: StAR mutations located in the cholesterol binding pocket (V187M, R188C, R192C, G221D/S seem to cause non-classic lipoid CAH. Accuracy of genotype-phenotype prediction by in vitro testing may vary with the assays employed.

    Six 46,XX patients with congenital adrenal hyperplasia (CAH) presented with genital ambiguity, five so severe that initial gender assignment was male. Once diagnosis was realized, parents were involved in evaluation and chose sex re-assignment as female. To date, these girls and their parents all indicate satisfaction with their decision for a female sex of rearing. The girls have a female gender identity with behavior characteristics known for females with CAH. Thus, while outcome is satisfactory, it is realized that for most, expression of sexual orientation and adult life adjustments have not yet occurred.

    Gonadotropin independent sexual precocity (SP) may be due to congenital adrenal hyperplasia (CAH), and its timing usually depends on the type of mutation in the CYP21A2 gene. Compound heterozygotes are common and express phenotypes of varying severity. The objective of this case report was to investigate the hormonal pattern and unusual genetic profile in a 7-year-old boy who presented with pubic hair, acne, an enlarged phallus, slightly increased testicular volume and advanced bone age. Clinical, hormonal and genetic studies were undertaken in the patient as well as his parents. We found elevated serum 17-hydroxyprogesterone (17-OHP) and androstenedione that were suppressed with dexamethasone, and elevated testosterone that actually rose after giving dexamethasone, indicating activity of the hypothalamic-pituitary-gonadal (HPG) axis. An initial search for common mutations was negative, but a more detailed genetic analysis of the CYP21A2 gene revealed two mutations including R341W, a non-classical mutation inherited from his mother, and g.823G>A, a novel not previously reported consensus donor splice site mutation inherited from his father, which is predicted to be salt wasting. However, the child had a normal plasma renin activity. He was effectively treated with low-dose dexamethasone and a GnRH agonist. His father was an unaffected carrier, but his mother had evidence of mild non-classical CAH. In a male child presenting with gonadotropin independent SP it is important to investigate adrenal function with respect to the androgen profile, and to carry out appropriate genetic studies.

    Steroid 21-hydroxylase deficiency is the most prevalent form of congenital adrenal hyperplasia (CAH), accounting for approximately 95% of cases. With the advent of newborn screening and hormone replacement therapy, most children with CAH survive into adulthood. Adolescents and adults with CAH experience a number of complications, including short stature, obesity, infertility, tumor, osteoporosis, and reduced quality of life. Transition from pediatric to adult care and management of long-term complications are challenging for both patients and health-care providers. Psychosocial issues frequently affect adherence to glucocorticoid treatment. Therefore, the safe transition of adolescents to adult care requires regular follow-up of patients by a multidisciplinary team including pediatric and adult endocrinologists. The major goals for management of adults with 21-hydroxylase deficiency are to minimize the long-term complications of glucocorticoid therapy, reduce hyperandrogenism, prevent adrenal or testicular adrenal rest tumors, maintain fertility, and improve quality of life. Optimized medical or surgical treatment strategies should be developed through coordinated care, both during transition periods and throughout patients' lifetimes. This review will summarize current knowledge on the management of adults with CAH, and suggested appropriate approaches to the transition from pediatric to adult care. PMID:28289431

    Adrenal cortical tumors are rare in children. Secondary tumors associated with untreated congenital adrenal hyperplasia (CAH) have also been reported in pediatric population. It is difficult for pediatricians to differentiate these 2 lesions.We described a 4.5-year-old girl who presented with symptoms and signs of virilization. Bone age was 9.5 years. Genetic analysis of CYP21A2 and CYP11B1 revealed a heterozygous mutation of CYP11B1 at c.1157C>T (A386V). No germline p53 gene mutation including R337H was detected.The patient was first misdiagnosed as CAH and treated with hydrocortisone for 3 months. Diagnosis of an adrenal cortical tumor was confirmed by laboratory data and abdominal computed tomography. After resection of the tumor, serum steroids normalized and clinical signs receded. The child received no additional treatment and remains disease free after 12 months of close observation. Histological examination showed neoplasia cells with predominantly eosinophilic cytoplasm and few atypical mitotic figures. The proliferation-associated Ki-67 index was <1% detected by immunohistochemistry.Neoplasm is a rare but significant cause of precocious puberty (PP). The possibility of neoplasms should always be considered early to avoid delayed cancer diagnosis and treatment in cases of PP.

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is an autosomal-recessive disease causing cortisol deficiency, aldosterone deficiency and hyperandrogenism. Diagnosis of 21-OHD is confirmed by steroid analysis in newborn screening or later on. Standard medical treatment consists of oral glucocorticoid and mineralocorticoid administration in order to suppress adrenal androgens and to compensate for adrenal steroid deficiencies. However, available treatment is far from ideal, and not much is known about the long-term outcome in CAH as trials in patients in adulthood or old age are rare. Here we briefly describe the pathophysiology, clinical picture, genetics and epidemiology of 21-OHD. This is followed by a comprehensive review of the recent advances in diagnosis, treatment and outcome. Novel insights have been gained in the fields of newborn screening, specific steroid measurement utilizing mass spectrometry, genetics, glucocorticoid stress dosing, additive medical therapy, prenatal treatment, side-effects of medical treatment, adrenomedullary involvement, metabolic morbidity, fertility and gender identity. However, many issues are still unresolved, and novel questions, which will have to be answered in the future, arise with every new finding.

    Key questions for developmentalists concern the origins of gender attitudes and their implications for behavior. We examined whether prenatal androgen exposure was related to gender attitudes, and whether and how the links between attitudes and gendered activity interest and participation were mediated by gender identity and moderated by hormones. Gender attitudes (i.e., gender-role attitudes and attitudes about being a girl), gender identity, and gender-typed activities were reported by 54 girls aged 10-13 years varying in degree of prenatal androgen exposure, including 40 girls with classical congenital adrenal hyperplasia (C-CAH) exposed to high prenatal androgens and 14 girls with non-classical (NC) CAH exposed to low, female-typical, prenatal androgens. Both girls with C-CAH and NC-CAH reported positive attitudes about being a girl and egalitarian gender attitudes, consistent with their female-typical gender identity. In contrast, girls with C-CAH had more male-typed activity interest and participation than girls with NC-CAH. Gender attitudes were linked to activities in both groups, with gender identity mediating the links. Specifically, gender-role attitudes and positive attitudes about being a girl were associated with feminine gender identity, which in turn was associated with decreased male-typed activity interests and participation, and increased female-typed activity interests. Our results are consistent with schema theories, with attitudes more closely associated with gender identity than with prenatal androgens.

    Summary Meningioma growth has been previously described in patients receiving oestrogen/progestogen therapy. We describe the clinical, radiological, biochemical and pathologic findings in a 45-year-old woman with congenital adrenal hyperplasia secondary to a defect in the 21-hydroxylase enzyme who had chronic poor adherence to glucocorticoid therapy with consequent virilisation. The patient presented with a frontal headache and marked right-sided proptosis. Laboratory findings demonstrated androgen excess with a testosterone of 18.1 nmol/L (0–1.5 nmol) and 17-Hydroxyprogesterone >180 nmol/L (sphenoid wing with anterior displacement of the right eye and associated bony destruction. Surgical debulking of the meningioma was performed and histology demonstrated a meningioma, which stained positive for the progesterone receptor. Growth of meningioma has been described in postmenopausal women receiving hormone replacement therapy, in women receiving contraceptive therapy and in transsexual patients undergoing therapy with high-dose oestrogen and progestogens. Progesterone receptor positivity has been described previously in meningiomas. 17-Hydroxyprogesterone is elevated in CAH and has affinity and biological activity at the progesterone receptor. Therefore, we hypothesise that patients who have long-standing increased adrenal androgen precursor concentrations may be at risk of meningioma growth. Learning points: Patients with long-standing CAH (particularly if not optimally controlled) may present with other complications, which may be related to long-standing elevated androgen or decreased glucocorticoid levels. Chronic poor control of CAH is associated with adrenal myelolipoma and adrenal rest tissue tumours. Meningiomas are sensitive to endocrine stimuli including progesterone, oestrogen and androgens as they express the relevant receptors. PMID:27933170

    2005-08-01

    This article reviews the literature on studies and case reports on gender identity and gender identity problems, gender dysphoria, and gender change in chromosomal females with congenital adrenal hyperplasia, raised male or female. The large majority (94.8%) of the patients raised female (N= 250) later developed a gender identity as girls and women and did not feel gender dysphoric. But 13 (5.2%) patients had serious problems with their gender identity. This percentage is higher than the prevalence of female-to-male transsexuals in the general population of chromosomal females. Among patients raised male, serious gender identity problems were reported in 4 (12.1%) out of 33 patients. From these observations, we conclude that the assignment to the female gender as a general policy for 46,XX patients with CAH appears justified, even in severely masculinized 46,XX newborns with CAH (Prader stage IV or V).

    To evaluate the radiological and clinical findings of congenital cystic neuroblastomas as compared with those of the cystic presentation of neonatal adrenal hemorrhage. We analyzed the US (n = 52), CT (n = 24), and MR (n = 4) images as well as the medical records of 28 patients harboring congenital cystic neuroblastomas (n = 16) and neonatal adrenal hemorrhagic pseudocysts (n = 14). The history of prenatal detection, location, size, presence of outer wall enhancement, internal septations, solid portion, calcification, turbidity, vascular flow on a Doppler examination, and evolution patterns were compared in two groups of cystic lesions, by Fischer's exact test. All (100%) neuroblastomas and three (21%) of the 14 hemorrhagic pseudocysts were detected prenatally. Both groups of cystic lesions occurred more frequently on the right side; 11 of 16 (69%) for neuroblastomas and 11 of 14 (79%) for hemorrhagic pseudocysts. The size, presence of solid portion, septum, enhancement, and turbidity did not differ significantly (p > 0.05) between the two groups of cystic lesions. However, tiny calcifications (n = 3) and vascular flow on color Doppler US (n = 3) were noted in only neuroblastomas. The cystic neuroblastomas became complex solid and cystic masses, and did not disappear for up to 90 days in the three following cases, whereas 11 of the 14 (79%) hemorrhagic pseudocysts disappeared completely and the three remaining (27%) evolved to calcifications only. Although the imaging findings of two groups of cystic lesions were similar, prenatal detection, the presence of calcification on initial images, vascularity on color Doppler US, and evolution to a more complex mass may all favor neuroblastomas

    Context: P450 oxidoreductase deficiency (PORD) is a unique congenital adrenal hyperplasia variant that manifests with glucocorticoid deficiency, disordered sex development (DSD), and skeletal malformations. No comprehensive data on genotype-phenotype correlations in Caucasian patients are available. Objective: The objective of the study was to establish genotype-phenotype correlations in a large PORD cohort. Design: The design of the study was the clinical, biochemical, and genetic assessment including multiplex ligation-dependent probe amplification (MLPA) in 30 PORD patients from 11 countries. Results: We identified 23 P450 oxidoreductase (POR) mutations (14 novel) including an exonic deletion and a partial duplication detected by MLPA. Only 22% of unrelated patients carried homozygous POR mutations. p.A287P was the most common mutation (43% of unrelated alleles); no other hot spot was identified. Urinary steroid profiling showed characteristic PORD metabolomes with variable impairment of 17α-hydroxylase and 21-hydroxylase. Short cosyntropin testing revealed adrenal insufficiency in 89%. DSD was present in 15 of 18 46,XX and seven of 12 46,XY individuals. Homozygosity for p.A287P was invariably associated with 46,XX DSD but normal genitalia in 46,XY individuals. The majority of patients with mild to moderate skeletal malformations, assessed by a novel scoring system, were compound heterozygous for missense mutations, whereas nearly all patients with severe malformations carried a major loss-of-function defect on one of the affected alleles. Conclusions: We report clinical, biochemical, and genetic findings in a large PORD cohort and show that MLPA is a useful addition to POR mutation analysis. Homozygosity for the most frequent mutation in Caucasians, p.A287P, allows for prediction of genital phenotype and moderate malformations. Adrenal insufficiency is frequent, easily overlooked, but readily detected by cosyntropin testing. PMID:22162478

    Summary Lipoid congenital adrenal hyperplasia (lipoid CAH), the most severe form of CAH, is most commonly caused by mutations in steroidogenic acute regulatory protein (STAR), which is required for the movement of cholesterol from the outer to the inner mitochondrial membranes to synthesize pregnenolone. This study was performed to evaluate whether the salt-losing crisis and the adrenal inactivity experienced by a Scandinavian infant is due to a de novo STAR mutation. The study was conducted at the University of North Dakota, the Mercer University School of Medicine and the Memorial University Medical Center to identify the cause of this disease. The patient was admitted to a pediatric endocrinologist at the Sanford Health Center for salt-losing crisis and possible adrenal failure. Lipoid CAH is an autosomal recessive disease, we identified two de novo heterozygous mutations (STAR c.444C>A (STAR p.N148K) and STAR c.557C>T (STAR p.R193X)) in the STAR gene, causing lipoid CAH. New onset lipoid CAH can occur through de novo mutations and is not restricted to any specific region of the world. This Scandinavian family was of Norwegian descent and had lipoid CAH due to a mutation in S TAR exons 4 and 5. Overexpression of the STAR p.N148K mutant in nonsteroidogenic COS-1 cells supplemented with an electron transport system showed activity similar to the background level, which was ∼10% of that observed with wild-type (WT) STAR. Protein-folding analysis showed that the finger printing of the STAR p.N148K mutant is also different from the WT protein. Inherited STAR mutations may be more prevalent in some geographical areas but not necessarily restricted to those regions. Learning points STAR mutations cause lipoid CAH.This is a pure population from a caucasian family.Mutation ablated STAR activity.The mutation resulted in loosely folded conformation of STAR.

    To address questions about sex assignment in children with ambiguous genitalia, we studied gender identity in girls with congenital adrenal hyperplasia (CAH) in relation to characteristics of the disease and treatment, particularly genital appearance and surgery. A 9-item gender identity interview was administered to 43 girls with classical CAH ranging in age from 3-18 yr, 7 tomboys, and 29 sister control girls. Groups were compared on total score and on individual items. Results showed that, on the total gender identity score, 88% of girls with CAH had scores overlapping those of control girls, but the average score was intermediate between control girls and tomboys. On individual items of gender identity (discomfort as a girl, wish to be a boy), girls with CAH were similar to control girls. Gender identity in girls with CAH was not related to degree of genital virilization or age at which genital reconstructive surgery was done. Thus, moderate androgen excess early in development appears to produce a small increase in the risk of atypical gender identity, but this risk cannot be predicted from genital virilization.

    Full Text Available Congenital adrenal hyperplasia (CAH is an autosomal recessive disorder and affects approximately 1 in 15,000 births in the United States. CAH is one of the disorders included on the Newborn Screening (NBS Recommended Uniform Screening Panel. The commonly used immunological NBS test is associated with a high false positive rate and there is interest in developing second-tier assays to increase screening specificity. Approximately 90% of the classic forms of CAH, salt-wasting and simple virilizing, are due to mutations in the CYP21A2 gene. These include single nucleotide changes, insertions, deletions, as well as chimeric genes involving CYP21A2 and its highly homologous pseudogene CYP21A1P. A novel loci-specific PCR approach was developed to individually amplify the CYP21A2 gene, the nearby CYP21A1P pseudogene, as well as any 30 kb deletion and gene conversion mutations, if present, as single separate amplicons. Using commercially available CAH positive specimens and 14 families with an affected CAH proband, the single long-range amplicon approach demonstrated higher specificity as compared to previously published methods.

    The most common cause of congenital adrenal hyperplasia (CAH) is the deficiency of cytochrome P450{sub 21} - a component of steroid 21-hydroxylase. This blocks the synthesis of glucocorticoids and mineralocorticoids and leads to excessive secretion of adrenal androgens. The functional gene of cytochrome P450{sub 21} (CYP21B) as well as its pseudogene (CYP21A), are located on the short arm of chromosome 6 p21.3. The detection of mutations of the CYP21B gene revealed that the main cause of CAH are conversions, deletions, insertions, duplications and point mutations, resulting in premature termination of transcription, frame shift, aberration of RNA splicing etc. Molecular methods most commonly employed in investigations of CYP21 gene were discussed and some results obtained with the use of these methods were presented. The most commonly used methods are: restriction fragment length polymerization, Southern blotting, DNA single strand conformation polymorphism and sequence analysis. Chemical cleavage method and denaturing gradient gel electrophoresis of the DNA fragments, or else applying the illegitimate DNA transcription, will hopefully facilitate detection of the mutations in the CYP21B gene. The application of the molecular methods enables precise prenatal diagnosis of CAH, which facilitates early and successful treatment. (author). 44 refs, 4 figs, 3 tabs.

    Full Text Available Introduction. Men with congenital adrenal hyperplasia (CAH due to 21-hydroxylase deficiency show impaired fecundity due to testicular adrenal rest tumors and/or suppression of the gonadal axis. Sexual well-being might be an additional factor; however, no data exists. Patients and Methods. Prospective longitudinal monocentric study included 20 male CAH patients (14 salt wasting, 6 simple virilizing; age 18–49 yr. Clinical assessment, testicular ultrasound, biochemical and hormonal parameters, three validated self-assessment questionnaires (SF-36, GBB-24, and HADS, and male Brief Sexual Function Inventory (BSFI were analyzed at baseline and after two years. Results. Basal LH and testosterone levels suggested normal testicular function. LH and FSH responses to GnRH were more pronounced in patients with a good therapy control according to androstenedione/testosterone ratio < 0.2. This group had significant higher percentage of patients on dexamethasone medication. GBB-24, HADS, and SF-36 showed impaired z-scores and no changes at follow-up. BSFI revealed impairments in dimensions “sexual drive,” “erections,” and “ejaculations,” whereas “problem assessment” and “overall satisfaction” revealed normal z-scores. Androstenedione levels correlated (P=0.036 inversely with z-scores for “sexual drive” with higher levels associated with impaired “sexual drive.” Conclusion. Male CAH patients showed a partly impaired sexual well-being which might be an additional factor for reduced fecundity.

    Congenital adrenal hyperplasia (CAH) is the most common cause of female pseudohermaphroditism in Indian children. It is caused by enzymatic defects in the steroidogenic pathway of the adrenal glands and is characterized by impaired cortisol and aldosterone synthesis and overproduction of androgens. The disease usually presents with life-threatening problems and virilization, with long term physical and psychological effects. The clinical and laboratory diagnoses play an important role in deciding the course of treatment, which continues lifelong. To ensure proper growth and development of the patient, optimized disease management and treatment with steroids is required. Often the patient also requires surgical correction. Recent developments in molecular genetics have greatly helped in understanding the pathogenesis of the disease. The gene encoding for steroid 21-hydroxylase, CYP21, is located on the short arm of chromosome 6 in the HLA region and is amplified for genetic diagnosis. Rapid characterization of point mutations is possible using the allele-specific polymerase chain reaction technique in affected children. Counselling, prenatal diagnosis and treatment are recommended in all pregnant women with a positive family history to reduce or eliminate the effects in affected foetuses. This spares the female newborn the consequences of genital ambiguity and problems of gender identity.

    With an estimated prevalence of 1 in 100 000 births, 11β-hydroxylase deficiency is the second most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in CYP11B1 Clinical features include virilization, early gonadotropin-independent precocious puberty, hypertension, and reduced stature. The current mainstay of management is with glucocorticoids to replace deficient steroids and to minimize adrenal sex hormone overproduction, thus preventing virilization and optimizing growth. We report a patient with CAH who had been suboptimally treated and presented to us at 6 years of age with precocious puberty, hypertension, tall stature, advanced bone age, and a predicted final height of 150 cm. Hormonal profiles and genetic analysis confirmed a diagnosis of 11β-hydroxylase deficiency. In addition to glucocorticoid replacement, the patient was commenced on growth hormone and a third-generation aromatase inhibitor, anastrozole, in an attempt to optimize his growth. After the initiation of this treatment, the patient's growth rate improved significantly and bone age advancement slowed. The patient reached a final height of 177.5 cm (0.81 SD score), 11.5 cm above his mid-parental height. This patient is only the second reported case of the use of an aromatase inhibitor in combination with growth hormone to optimize height in 11β-hydroxylase-deficient CAH. This novel treatment proved to be highly efficacious, with no adverse effects. It may therefore provide a promising option to promote growth in exceptional circumstances in individuals with 11β-hydroxylase deficiency presenting late with advanced skeletal maturation and consequent short stature.

    This study evaluated the degree of femininity and masculinity at different developmental stages in a group of adult women, some of whom were exposed to elevated prenatal adrenal androgens as a result of congenital adrenal hyperplasia (CAH) due to 21 hydroxylase (21-OH) deficiency. Women who had presented to the Johns Hopkins Hospital Pediatric Endocrine Clinic for treatment of CAH due to 21-OH deficiency were included. The control group consisted of sisters of CAH participants and women referred for evaluation of polycystic ovary syndrome. Study participants were given a questionnaire asking them to indicate their degree of masculinity and femininity during childhood, adolescence, and adulthood. In addition, participants were asked questions related to their play behavior during childhood, including playmate preferences, toy preferences, and admiration of male or female characters during fantasy play. Across participant groups, self-reported femininity decreased in a dose response manner, according to prenatal androgen exposure. For all groups, femininity increased through developmental stages. Women with salt-losing CAH remained less feminine than controls into adulthood. Conversely, self-reported masculinity increased in a dose-response manner, according to prenatal androgen exposure, across participant groups. Women with CAH showed a decrease in masculinity across developmental stages, such that by adulthood, there were no significant differences in masculinity between controls and the women with CAH. Women with salt-losing CAH were more likely to recall preferences for boy playmates, male-typical toys, and admiration for male characters during childhood than other study participants. Our data support the effect of both prenatal androgen exposure and socialization on gender role behavior in adult women with CAH due to 21-OH deficiency.

    Congenital adrenal hyperplasia (CAH) is a disorder of steroid genesis affecting approximately 1:10 000 children and leading to increased levels of androgens during foetal life and subsequent virilization of external genitalia in affected girls. However, prenatal virilization can be eliminated by antenatal dexamethasone (DEX) treatment. To be fully effective, DEX treatment has to be started in the 6–7th postmenstrual week and continued until the results of the prenatal diagnosis are available ...

    Three male infants with vomiting, dehydration, hyponatremia, hyperkalemia and metabolic acidosis were found to have vesicoureteral reflux (VUR) and urinary tract infection. Two were initially thought to have the salt-losing form of congenital adrenal hyperplasia. Although prompt diagnosis of this potentially fatal condition is critical, its mimicry by urosepsis in infants with VUR is actually more common. Infection probably causes unresponsiveness of the distal renal tubules to aldoterone. (orig.).

    Full Text Available A 33-year-old male with a history of left testis Leydig cell tumor (LCT, 3-month status after left radical orchiectomy, presented with a rapidly enlarging (0.6 cm to 3.7 cm right testicular mass. He underwent a right radical orchiectomy, sections interpreted as showing a similar Leydig cell-like oncocytic proliferation, with a differential diagnosis including metachronous bilateral LCT and metachronous bilateral testicular tumors associated with congenital adrenal hyperplasia (a.k.a. “testicular adrenal rest tumors” (TARTs and “testicular tumors of the adrenogenital syndrome” (TTAGS. Additional workup demonstrated a markedly elevated serum adrenocorticotropic hormone (ACTH and elevated adrenal precursor steroid levels. He was diagnosed with congenital adrenal hyperplasia, 3β-hydroxysteroid dehydrogenase deficiency (3BHSD type, and started on treatment. Metachronous bilateral testicular masses in adults should prompt consideration of adult presentation of CAH. Since all untreated CAH patients are expected to have elevated serum ACTH, formal exclusion of CAH prior to surgical resection of a testicular Leydig-like proliferation could be accomplished by screening for elevated serum ACTH.

    Congenital adrenal hyperplasia (CAH) is an inherited autosomal recessive disorder characterized by insufficient production of cortisol. The aim of this case report was to present a child with CAH, premature exfoliation of primary teeth and accelerated eruption of his permanent teeth related to bone resorption. A 4.5-year-old Caucasian boy with CAH and long-term administration of glucocorticoids was referred for dental restoration. Clinical examination revealed primary molars with worn stainless steel crowns, severe attrition of the upper canines, and absence of the upper incisors. Before the completion of treatment, abnormal mobility of the first upper primary molars and the lower incisors was detected, and a few days later the teeth exfoliated prematurely. Histologic examination revealed normal tooth structure. Alkaline phosphatase and blood cells values were normal. Eruption of the permanent dentition was also accelerated. Tooth mobility was noticed in the permanent teeth as soon as they erupted, along with bone destruction. Examination revealed an elevated level of receptor activator of nuclear factor-κB ligand and lower-than-normal osteoprotegerin and vitamin D levels. The patient was treated with vitamin D supplements, and his teeth have been stable ever since. CAH is a serious chronic disorder appearing in children with accelerated dental development and possibly premature loss of primary teeth.

    Congenital adrenal hyperplasia (CAH), resulting from mutations in CYP11B1, a gene encoding 11β-hydroxylase, represents a rare autosomal recessive Mendelian disorder of aberrant sex steroid production. Unlike CAH caused by 21-hydroxylase deficiency, the disease is far more common in the Middle East and North Africa, where consanguinity is common often resulting in identical mutations. Clinically, affected female newborns are profoundly virilized (Prader score of 4/5), and both genders display significantly advanced bone ages and are oftentimes hypertensive. We find that 11-deoxycortisol, not frequently measured, is the most robust biochemical marker for diagnosing 11β-hydroxylase deficiency. Finally, computational modeling of 25 missense mutations of CYP11B1 revealed that specific modifications in the heme-binding (R374W and R448C) or substrate-binding (W116C) site of 11β-hydroxylase, or alterations in its stability (L299P and G267S), may predict severe disease. Thus, we report clinical, genetic, hormonal, and structural effects of CYP11B1 gene mutations in the largest international cohort of 108 patients with steroid 11β-hydroxylase deficiency CAH.

    Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency need glucocorticoid (GC) therapy, which alters bone mineral metabolism. We analyze clinical and biochemical parameters and different polymorphisms of candidate genes associated with bone mineral density (BMD) in CAH patients. The CAH patients treated with GC and healthy controls were studied. Anthropometric parameters, biochemical markers of bone turnover, and BMD were evaluated. Polymerase chain reaction technique was used to genotype different candidate genes. The 192-192 genotype frequency (IGF-I) was lower in poorly controlled patients than that from controls. In CAH patients, FF genotype (vitamin D receptor, VDR) correlated with lower lumbar spine BMD and there was a significant association between the 0-0 genotype (IGF-I) and high values of β-CrossLaps and a low total BMD. This study contributes to understanding of the association of genetic determinants of BMD with the variable response to GC treatment in CAH patients and demonstrates the usefulness of these genetic polymorphisms.

    2017-01-01

    Surgical management of classical congenital adrenal hyperplasia (CAH) in 46, XX females has evolved significantly. Virilization of the genitalia of 46, XX females with CAH begins prenatally as a result of excess fetal androgen production. Improved understanding of anatomy and surgical outcomes has driven changes in surgical techniques as well as the timing of surgery. For endocrinologists treating these patients, it is important to understand the outcome of genitoplasty, identify patients who need further treatment and direct these patients to experienced surgeons. We performed a literature search on PubMed of publications addressing CAH and genital reconstruction published in the English language from 1990 to the present. In accordance with our institutional review board, we performed a retrospective analysis of clitoroplasty and/or vaginoplasty procedures performed by a single surgeon at our institution from 1996 to 2015. We found that genital reconstruction in 46, XX CAH patients is associated with few immediate post-operative, infectious, and urinary complications. Vaginal stenosis is a common complication of vaginal reconstruction and requires evaluation by an experienced surgeon. Clitoral pain or decreased sensation can be associated with clitoral recession and clitorectomy. Outcomes in sexual satisfaction and gender identity can also be impacted by surgical technique and success. Long term follow up and patient reported feedback are crucial to our understanding and management of this special group of patients. Improved awareness and understanding of the complications of genital surgery will allow endocrinologists to know what to ask patients and be ready to provide them with a resource with the understanding and experience to help them improve their quality of life.

    Full Text Available Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 - 21. Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation.

    CYP21A2 gene mutations in a child with congenital adrenal hyperplasia (CAH), and the child's parents, were detected in the study. The clinical features, treatment monitoring and molecular genetic mechanism of CAH are reviewed. In the study, DNA was extracted from peripheral blood samples using the QIAGEN Blood DNA Mini Kit; a highly specific PCR primer for CYP21A2 gene was designed according to the sequence difference between CYP2lA2 gene and its pseudogene; the whole CYP2lA2 gene was amplified with PrimeSTAR DNA polymerase (Takara), and the amplification product was directly sequenced to detect and analyze CYP2lA2 gene mutation. The child was clinically diagnosed with CAH (21-hydroxylase deficiency, 21-OHD) at the age of 36 days, and the case was confirmed by genetic diagnosis at the age of 1.5 years. The proband had a homozygous mutation at c.293-13C in the second intron of CYP21 gene, while the parents had heterozygous mutations. Early diagnosis and standard treatment of CAH (21-OHD) should be performed to prevent salt-wasting crisis and reduce mortality; bone aging should be avoided to increase final adult height (FAH), and reproductive dysfunction due to oligospermia in adulthood should be avoided. These factors are helpful for improving prognosis and increasing FAH. Investigating the molecular genetic mechanism of CAH can improve recognition and optimize diagnosis of this disease. In addition, carrier diagnosis and genetic counseling for the proband family are of great significance.

    Full Text Available Background: There is equipoise regarding the status of bone mineral density (BMD in patients with congenital adrenal hyperplasia (CAH, where patients need to be on long-term low-dose steroids. Objective: We aimed to evaluate BMD at the hip, spine and forearm in women with CAH and compare it to healthy young adult women of the same age range. Subjects and Methods: Fifteen adult women with CAH with age ranging from 18 to 40 years (mean ± standard deviation = 27.5 ± 6.2 years underwent dual-energy X-ray absorptiometry along with laboratory evaluation. BMD at lumbar spine, hip, forearm along with T-scores were measured. Serum total calcium, phosphate, alkaline phosphatase, 25 hydroxy Vitamin D, intact parathyroid hormone, total testosterone, and dehydroepiandrosterone were assayed. History of any fractures in the past was taken. Fifteen healthy women in the same age range were taken as controls for comparison. Results: The BMD at hip (0.85 ± 0.02 g/cm2 in CAH was significantly lower as compared with controls (0.92 ± 0.03 g/cm2, P = 0.029. BMD at lumbar spine was also reduced (0.96 ± 0.02 vs. 1.03 ± 0.03, P = 0.057. The BMD at forearm was not significantly different between CAH and controls. The mean Vitamin D was 9.8 ng/ml (deficient range. There was no history of fractures in CAH. Conclusion: Young adult CAH women had lower BMD at spine and hip than healthy young adult women of the same age range. The forearm BMD was not different from controls. No change in fracture frequency was present. Patients with CAH being treated with steroids are at increased risk of osteopenia, and their bone health needs to be monitored.

    Aim: To evaluate the clinical profile and management of 46 XX Congenital Adrenal Hyperplasia (CAH) patients presenting with severe virilization and assigned a male gender. Materials and Methods: Of 173 children diagnosed with CAH at the Pediatric Intersex Clinic since 1980, seven children with CAH presented late with severe virilization and were reared as males. All of them were assigned the male sex with removal of the female adnexa. Six were treated with male genitoplasty. Appropriate hormonal supplementation was offered after puberty. Results: The mean age at presentation was 14.2 years (7 – 21). Six patients had presented after puberty, only one at seven years of age. Staged male genitoplasty comprising of chordee correction, male urethroplasty, and bilateral testicular prosthesis was performed. The female adnexa (uterus, ovaries, most of the upper vagina, and the fallopian tubes) were removed. The mental makeup was masculine in six and bigender in one. Bilateral mastectomy was performed at puberty in all. Hormonal treatment comprised of glucocorticoids and testosterone. Six patients were comfortable with the outcome of the masculinizing genitoplasty. One had a short-sized phallus. One had repeated attacks of urinary tract infection arising from the retained lower vaginal pouch. Social adjustments were good in all, except in one who had a bigender mental makeup. Conclusion: CAH patients with severe virilization presenting late and reared as males are extremely rare. However, the assigned gender can be retained adequately as males, meeting the socioeconomic compulsions of the society. The results are satisfactory following appropriate surgical procedures and hormonal supplementation. PMID:23226638

    Full Text Available Congenital adrenal hyperplasia is a group of autosomal recessive disorders. The most frequent one is 21-hydroxylase deficiency. Analyzing CYP21A2 gene mutations was so far not reported in Iraq. This work aims to analyze the spectrum and frequency of CYP21A2 mutations among Iraqi CAH patients. Sixty-two children were recruited from the Pediatric Endocrine Consultation Clinic, Children Welfare Teaching Hospital, Baghdad, Iraq, from September 2014 till June 2015. Their ages ranged between one day and 15 years. They presented with salt wasting, simple virilization, or pseudoprecocious puberty. Cytogenetic study was performed for cases with ambiguous genitalia. Molecular analysis of CYP21A2 gene was done using the CAH StripAssay (ViennaLab Diagnostics for detection of 11 point mutations and >50% of large gene deletions/conversions. Mutations were found in 42 (67.7% patients; 31 (50% patients were homozygotes, 9 (14.5% were heterozygotes, and 2 (3.2% were compound heterozygotes with 3 mutations, while 20 (32.3% patients had none of the tested mutations. The most frequently detected mutations were large gene deletions/conversions found in 12 (19.4% patients, followed by I2Splice and Q318X in 8 (12.9% patients each, I172N in 5 (8.1% patients, and V281L in 4 (6.5% patients. Del 8 bp, P453S, and R483P were each found in one (1.6% and complex alleles were found in 2 (3.2%. Four point mutations (P30L, Cluster E6, L307 frameshift, and R356W were not identified in any patient. In conclusion, gene deletions/conversions and 7 point mutations were recorded in varying proportions, the former being the commonest, generally similar to what was reported in regional countries.

    Patients with Congenital Adrenal Hyperplasia (CAH) owing to 21-hydroxylase deficiency and whose karyotype is 46, XX are usually assigned to the female gender. Reported herein are the long term outcomes in three patients with CAH whose karyotype is 46, XX and who were reared as males. A retrospective review of three CAH patients with a 46, XX karyotype who were reared as males was conducted. Gender assignment, clinical and biochemical data, pre and post-genitoplasty genital examinations were reviewed. Gender identity was tested by an extensive questionnaire. Gender role, sexual preference, marital status and sexual satisfaction were evaluated by interview. The three patients were genotyped for the CYP21A2 gene confirming the diagnosis of CAH. Owing to genital virilization, cultural preferences for male gender and the lack of newborn screening programs the three patients reported herein were assigned to the male gender at birth before the diagnosis of CAH was established. In adulthood the patients remained significantly virilized. Thorough psychosexual assessments in adulthood revealed well established male gender identities compatible with their male gender assignments at birth. In all three patients, gender role and behavior were consistent with male gender identity including sexual intercourse with female partners. The three patients reported herein revealed that male gender assignment to CAH patients with a 46, XX karyotype may have a successful outcome providing there is strong parental support and expert endocrine care. No standard guidelines have been published for the gender assignment of CAH patients with a 46, XX karyotype and genital ambiguity. More studies concerning gender assignment in CAH patients with a 46, XX karyotype reared as males are needed.

    Full Text Available Background: In congenital adrenal hyperplasia (CAH with ambiguous genitalia, assigning gender of rearing can be complex, especially If genitalia is highly virilized. Apart from karyotype, prenatal androgen exposure, patient's gender orientation, sociocultural, and parental influences play a role. The aim of this study was to assess gender dysphoria and psychosocial issues in patients of CAH raised as males and females. Materials and Methods: This is a cross-sectional study that includes patients (old and new with CAH who were treated by us in the last 6 months. A semi-structured interview proforma was used to elicit history and psychosocial background of the patients. The clinical and biochemical details were noted. For psychological analysis, patients were screened for gender dysphoria using Parent Report Gender Identity Questionnaire for children <12 years and Gender Identity/Gender Dysphoria Questionnaire for Adolescents and Adults. Results: We analyzed 22 46 XX CAH patients among which, 3 were reared as males and 19 as females. Among the 19 patients reared as females, 17 patients showed no gender dysphoria. Two patients revealed gender dysphoria as indicated by their marginally low scores on the gender dysphoria assessment. However, in view of current literature and the age groups of the patients, behavior of the 6-year-old patient can be best understood as being tomboyish. Gender dysphoria in the 22-year-old can be explained by the dominance of psychosocial factors and not hormones alone. Among the three patients reared as males, two prepubertal were satisfied with their male gender identity. The third patient, aged 32 years, had gender dysphoria when reared as a male that resolved when gender was reassigned as female and feminizing surgery was done. Conclusion: Gender assignment in 46 XX CAH is guided by factors such as degree of virilization of genitalia, gender orientation, patient involvement, sociocultural, and parental influences.

    Analyzing the long-term outcome in females with congenital adrenal hyperplasia (CAH) is crucial to evaluate effectiveness of treatment strategies. The aim of the study was to evaluate the long-term results in patients with CAH after feminizing surgery from the pediatric intersex clinic. Of 163 patients of CAH being followed (1980-2005), 50 responded for review. The patients had undergone feminizing genitoplasty and hormonal therapy. Evaluation included filling a detailed questionnaire along with physical examination and a structured interview in privacy. Assessment was performed for cosmetic results (50), psychosocial adjustment (42) above 5-year age, and functional outcome in 19 cases above 14-year age. Mean age at clitoroplasty was 3.6 years (1-16 years) and at time of the study was 14.6 years (4-23 years), with a mean post-op follow up of 6 years after the final surgery (6 months-17 years). The cosmetic outcome of clitoroplasty was excellent in 37, satisfactory in 10, and poor in 3. Gender identity was female, male, and mixed in 45, 4, and 1, respectively. The attitude to self and life was positive in 36 and negative in 6. The functional outcome of vaginoplasty was satisfactory, unsatisfactory, and undetermined in 11, 4, and 4, respectively. Endocrine control was satisfactory in 36/50. A novel assessment system has been adopted for analyzing the results of clitoroplasty and vaginoplasty. Endocrine control and surgical treatment are complimentary to each other to achieve satisfactory results in majority of CAH patients.

    Full Text Available In this study, 285 cases of congenital adrenal hyperplasia who were followed in the Tehran University Hospitals and Institute of Endocrinology and Metabolism arc reported. Among these cases, 165 (57.9% were female and 120 (42.1%, male. The most common type of congenital adrenal hyperplasia in these patients was the salt-losing type of 21-hydroxylase deficiency (57.9%; 11-hydroxylase deficiency was present in 13.68% of patients. There were only 3 cases with 3-beta hydroxysteroid dehydrogenase deficiency, 2 cases with 17-alphahydroxylase deficiency and one with 20, 22-desmolase deficiency. Presenting complaints were in decreasing order of frequency: ambiguous genitalia, vomiting and dehydration, precocious puberty, hypertension, failure to thrive, hirsutism and primary amenorrhea. The age of patients at the time of diagnosis was between 2 days to 17 years and the most common age was in the first two years of life especially in the neonatal period."nA positive family history of the same disease was present in 17 siblings of our patients. (21-OHD = 14 H-OHD=3. There were 27 cases of death among these patients (23 male and 4 female that 24 cases had 21-OHD and 2 cases had 3 beta HSD deficiency and one case had 20,22-desmolase deficiency .

    Full Text Available Abstract Background Most research concerning congenital adrenal hyperplasia (CAH and related conditions caused by primary adrenal insufficiency, such as Addison's or Cushing's disease, has focused on medical aspects rather than on patients' quality of life. Therefore, our objective was to investigate the physical, social and societal functioning of children with CAH and their parents in a Dutch population. Methods The study is descriptive and cross-sectional. Self-designed questionnaires, based on questionnaires developed in the Netherlands for different patient groups, were sent to parents of children with CAH between 0 and 18 years old. Participants were recruited through the Dutch patient group for Adrenal Disease (NVACP and six hospitals in the Netherlands. Three different questionnaires were designed for parents: for children aged 0 - 4, aged 4 - 12 and aged 12 - 18. Additionally, a fourth questionnaire was sent to adolescents with CAH aged 12 - 18. Main outcome measures were experienced burden of the condition, self-management and participation in several areas, such as school and leisure time. Results A total of 106 parents returned the questionnaire, 12 regarding pre-school children (0-4 years, 63 regarding primary school children (4-12 years, and 32 regarding secondary school children (12-18 years, combined response rate 69.7%. Also, 24 adolescents returned the questionnaire. Children and adolescents with CAH appear to be capable of self-management at a young age. Experienced burden of the condition is low, although children experience several health related problems on a daily basis. Children participate well in school and leisure time. Few children carry a crisis card or emergency injection with them. Conclusions Overall, our research shows that, according to their parents, children with CAH experience few negative effects of the condition and that they participate well in several areas such as school and leisure time.

    We administered the 18-item Recalled Childhood Gender Questionnaire-Revised (RCGQ-R), female version, to 147 adult women with congenital adrenal hyperplasia (CAH) representing three different degrees of prenatal androgenization due to 21-hydroxylase deficiency and to non-CAH controls. A principal components analysis generated three components accounting for 46%, 9%, and 6% of the variance, respectively. Corresponding unit-weighted scales (high scores = feminine) were labeled Gender Role (13 items; Cronbach alpha = .91), Physical Activity (3 items; alpha = .64), and Cross-Gender Desire (2 items; alpha = .47). Discriminant validity was demonstrated in terms of highly significant comparisons across the four groups. We conclude that the first 2 RCGQ-R scales show good psychometric qualities, but that the third scale needs to be further evaluated in a sample that includes women with gender identity disorder.

    P450 oxidoreductase deficiency (PORD) is a variant of congenital adrenal hyperplasia that is caused by POR gene mutations. The POR gene encodes a flavor protein that transfers electrons from nicotinamide adenine dinucleotide phosphate (NADPH) to all microsomal cytochrome P450 type II (including 21-hydroxylase, 17α-hydroxylase 17,20 lyase and aromatase), which is fundamental for their enzymatic activity. POR mutations cause variable impairments in steroidogenic enzyme activities that result in wide phenotypic variability ranging from 46,XX or 46,XY disorders of sexual differentiation, glucocorticoid deficiency, with or without skeletal malformations similar to Antley-Bixler syndrome to asymptomatic newborns diagnosed during neonatal screening test. Little is known about the PORD long-term evolution. We described a 46,XX patient with mild atypical genitalia associated with severe bone malformation, who was diagnosed after 13 years due to sexual infantilism. She developed large ovarian cysts and late onset adrenal insufficiency during follow-up, both of each regressed after hormone replacement therapies. We also described a late surgical approach for the correction of facial hypoplasia in a POR patient.

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is caused by mutations in the CYP21A2 gene. The residual enzyme activity is strongly associated with the phenotype. We describe a rare case of CAH with a rare CYP21A2 mutation. The patient was a one-year-old Japanese boy. At 16 days old, he was referred to our hospital because of elevated serum 17-OH-progesterone (17-OHP) levels in neonatal screening. The compound heterozygous mutations (IVS2-13 A/C>G, and p.E431K) in CYP21A2 were identified at 2 months old, and we diagnosed non-classical CAH, since he did not have significant physical signs (pigmentation and salt-wasting). However, his body weight decreased, and his serum 17-OHP level (99.5 ng/mL) was elevated at 3 months old. Steroid replacement therapy was started at 3 months old. Our patient's clinical course resembled simple virilizing (SV) CAH, but classification was difficult because the patient showed increased renin activity indicating an aldosterone deficiency, and late onset of symptoms. While the IVS 2-13 A/C>G mutation is common in the classical form of CAH, p.E431K is a rare point mutation. Functional analysis revealed that the residual enzyme activity of p.E431L was 5.08±2.55% for 17-OHP and 4.12±2.37% for progesterone, which is consistent with SV CAH. p.E431 is localized in the L-helix near the heme-binding site. The mutation might interfere with heme binding, leading to deactivation of CYP21A2. This report showed that CYP21A2 p.E431 has an important effect on enzyme activity.

    Lipoid congenital adrenal hyperplasia (Lipoid CAH) is the most severe form of the autosomal recessive disorder CAH. A general loss of the steroid biosynthetic activity caused by defects in the StAR gene manifests as life-threatening primary adrenal insufficiency. We report a case of Lipoid CAH caused by a so far not described homozygous deletion of the complete StAR gene and provide diagnostic results based on a GC-MS steroid metabolomics and molecular genetic analysis. The patient presented with postnatal hypoglycemia, vomiting, adynamia, increasing pigmentation and hyponatremia. The constellation of urinary steroid metabolites suggested Lipoid CAH and ruled out all other forms of CAH or defects of aldosterone biosynthesis. After treatment with sodium supplementation, hydrocortisone and fludrocortisone the child fully recovered. Molecular genetic analysis demonstrated a homozygous 12.1 kb deletion in the StAR gene locus. The breakpoints of the deletion are embedded into two typical genomic repetitive Alu Sx elements upstream and downstream of the gene leading to the loss of all exons and regulatory elements. We established deletion-specific and intact allele-specific PCR methods and determined the StAR gene status of all available family members over three generations. This analysis revealed that one of the siblings, who died a few weeks after birth, carried the same genetic defect. Since several Alu repeats at the StAR gene locus increase the probability of deletions, patients with typical symptoms of lipoid CAH lacking evidence for the presence of both StAR alleles should be analyzed carefully for this kind of disorder.

    Full Text Available Management of congenital adrenal hyperplasia (CAH from embryonic stage to adulthood is a critical challenge. We would like to comment on some of the practical difficulties in offering prenatal treatment for CAH-affected fetuses in Indian population. For initiating the prenatal dexamethasone (DEX treatment, all members of the family need to be informed about the risks and benefits of the treatment to the mother and the fetus as well as about the available invasive diagnostic tests to determine the gender and genotype of the fetus. Prenatal sex disclosure is not routinely practiced in India due to high female feticide rate. The treatment has to be given to both unaffected and affected female fetuses until the determination of prenatal sex. Moreover, most of our populations reside in rural areas where the antenatal care is not adequate. Prenatal DEX treatment in India outruns the risks rather than the benefits, as evident from the literature on the safety of pregnant mothers and fetuses.

    Hemiconvulsion-Hemiplegia (HH) syndrome represents an uncommon consequence of prolonged unilateral clonic or hemiconvulsive status epilepticus in childhood, usually occurring during a febrile illness, followed by ipsilateral hemiplegia. The subsequent appearance of focal seizures configures the so called Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome. The pathogenesis of HH/HHE syndrome is still unclear. We describe the case of a 4 year-old girl with congenital adrenal hyperplasia (CAH) whom developed HH/HHE syndrome with drug resistant seizures at the age of 21 months and underwent left cerebral hemispherotomy at the age of 3 years and 6 months. Histopathological findings showed the presence of an underlying inflammatory-degenerative process. Disregulation of the inflammatory cascade has been proposed as one of the possible pathogenetic mechanisms underlying HH/HHE syndrome. To our knowledge however, this is the first report of an association with a histologically documented inflammatory process. The clinical and histopathological findings of our reported case lend support to the possible role of inflammation in the pathogenesis of HH/HHE syndrome.

    Steroid hormones modulate memory in animals and human adults. Little is known on the developmental effects of these hormones on the neural networks underlying memory. Using Congenital adrenal hyperplasia (CAH) as a naturalistic model of early steroid abnormalities, this study examines the consequences of CAH on memory and its neural correlates for emotionally arousing and neutral material in children. Seventeen patients with CAH and 17 age- and sex-matched healthy children (ages 12-14 years) completed the study. Subjects were presented positive, negative and neutral pictures. Memory recall occurred about 30min after viewing the pictures. Children with CAH showed memory deficits for negative pictures compared to healthy children (p0.1). In patients, 24h urinary-free cortisol levels (reflecting glucocorticoid replacement therapy) and testosterone levels were not associated with memory performance. These findings suggest that early steroid imbalances affect memory for negative material in children with CAH. Such memory impairments may result from abnormal brain organization and function following hormonal dysfunction during critical periods of development.

    Full Text Available Congenital adrenal hyperplasia (CAH due to steroid 11β-hydroxylase deficiency is the second most common form of CAH, resulting from a mutation in the CYP11B1 gene. Steroid 11β-hydroxylase deficiency results in excessive mineralcorticoids and androgen production leading to hypertension, precocious puberty with acne, enlarged penis, and hyperpigmentation of scrotum of genetically male infants. In the present study, we reported 3 male cases from a Saudi family who presented with penile enlargement, progressive darkness of skin, hypertension, and cardiomyopathy. The elder patient died due to heart failure and his younger brothers were treated with hydrocortisone and antihypertensive medications. Six months following treatment, cardiomyopathy disappeared with normal blood pressure and improvement in the skin pigmentation. The underlying molecular defect was investigated by PCR-sequencing analysis of all coding exons and intron-exon boundary of the CYP11B1 gene. A novel biallelic mutation c.780 G>A in exon 4 of the CYP11B1 gene was found in the patients. The mutation created a premature stop codon at amino acid 260 (p.W260∗, resulting in a truncated protein devoid of 11β-hydroxylase activity. Interestingly, a somatic mutation at the same codon (c.779 G>A, p.W260∗ was reported in a patient with papillary thyroid cancer (COSMIC database. In conclusion, we have identified a novel nonsense mutation in the CYP11B1 gene that causes classic steroid 11β-hydroxylase deficient CAH. Cardiomyopathy and cardiac failure can be reversed by early diagnosis and treatment.

    Nine female adolescents with female pseudohermaphroditism resulting from virilizing congenital adrenocortical hyperplasia (CAH) were studied in terms of gender identity, sex-role behavior, psychological adjustment, and psychosexual development. A group of adolescents with chronic illness was used as a control. The Draw-A-Person, the Bem Sex-Role Inventory, Rorschach, TAT, and a questionnaire reviewing peer and romantic activities were administered to both groups. The two groups were comparable on measures of general personality adjustment, with the CAH girls showing a trend toward greater bodily concerns. Sex-role identity for both groups was near the adolescent girl norms for both Femininity and Masculinity, with virilized CAH girls showing slightly higher Androgyny scores. Significant differences were found on gender identity as measured by greater differentiation of the drawn male figure as well as a trend toward drawing the male figure first. The CAH females also showed consistent patterns of psychosocial delay in dating and sexual relations as compared to the control group. Gender identity in this group appears to be mediated by body image. The resulting ambivalence may be evidence of feelings of incompetence, leading to resistance to social interactions and goals involving intimacy and nurturance.

    Full Text Available Objective: our objective was to display the presentation of simple virilizing Congenital Adrenal Hyperplasia (CAH with genital ambiguity and severe virilization of the external genitalia, influencing growth, height and weight, bone maturation, quality of life and hence undergoing genitoplasty. Surgical treatment was aimed to obtain a more natural psychological and sexual development and the type of surgical repair performed was tailored based on individual patient’s anatomy findings.Case: we report a case of a 3-year old female with simple virilizing CAH, diagnosed due to genital ambiguity, severe virilization, clitoromegaly, external genital pigmentation, precocious pubic hair, previously was under treatment with glucocorticoid replacement therapy for 2years since newborn and neglected due to discontinuing the hormonal treatment for one year duration, underwent several clinical studies including chromosomal study for sex determining, pelvic ultrasonography for internal anatomical details and bone age study for skeletal maturation, givenstress dose steroids pre-operatively and followed by genital reconstructive surgery (genitoplasty. A clitorectomy and labioplasty approach were performed. At time of surgery cystoscopy was carried out prior to the surgical repair.Results: Management of virilizing CAH child with ambiguous genitalia demands multidisciplinary and interdisciplinary approach. The team‘s major challenge is to use thefeasible means to make the least bad choice in order to select a gender able to match the individualidentity, social identity, and behavioral identity. Surgical option should be tailored, one stage surgery,at early age and performed according to the individual anatomy findings.

    Full Text Available Purpose: Genital reconstruction in female patients with virilizing congenital adrenal hyperplasia (CAH is very challenging. Our aim was to evaluate the techniques employed to treat complications after failure of primary urogenital sinus (UGS surgery, as well as the result of these reoperations.Patients and Methods: Twenty girls with virilizing CAH who were previously submitted to genitoplasty in our service and elsewhere had recurrent UGS stenosis and vaginal introitus stenosis that required surgical treatment. The main symptoms were recurrent urinary tract infection (UTI in nine, dyspareunia in six and hematocolpos in three (two associated with sepsis. The anatomical findings were the persistence of UGS with stenosis in 17 patients and vaginal introitus stenosis in three. The mean age at procedure was 15.2 yrs., averaging 13.1 yrs. after the first surgery. The surgical techniques employed were: isolated perineal flap in 17 patients and perineal flap with partial mobilization of UGS in three. The mean follow-up after the procedure was 4.8 years (varying from 1 to 17yrs.Results: Vaginal dilations were performed after surgery in 15 patients. Good functional and anatomical results were obtained in 15 patients, with vaginal introitus amenable to dilators of 3.0 cm in diameter. Five patients with high vaginal insertion had recurrent vaginal stenosis and required a surgical revision. No patients presented menstrual obstruction or UTI after surgery. Eight of the 15 adult patients are sexually active. Conclusion: The reoperation to treat failed primary UGS treatment using Y-V flap and partial mobilization techniques associated to vaginal dilations, promoted good anatomical and functional results with low morbidity in 75% of the patients.□

    Successful management of hyponatremia in heart failure patients requires a multifaceted approach in order to preserve end-organ function. We describe the novel use of a selective vasopressin receptor antagonist, tolvaptan, for management of hyponatremia in a 17-year-old Caucasian male with severe Duchenne muscular dystrophy, congestive heart failure (CHF), and congenital adrenal hyperplasia. The medical history was significant for recurrent admissions for hyponatremia secondary to adrenal crises, which was also exacerbated by his CHF. After initiation of tolvaptan and its extended administration, he had no further hyponatremia-related admissions and no adverse reactions. The complexity of this combination of conditions is presented, and the efficacy of the drug and the rationale behind the treatment approach is discussed.

    Congenital adrenal hyperplasia is a group of autosomal recessive disorders most often caused by deficiency of steroid 21-hydroxylase due to mutations in the CYP21 gene. We studied the functional and structural consequences of two novel missense mutations in the CYP21 gene, detected in two simple virilizing congenital adrenal hyperplasia patients. Both the male and female patient were compound heterozygous for the novel I77T and A434V point mutations, respectively. The in vitro expression analysis in COS-7 cells revealed a reduced 21-hydroxylase activity in the I77T mutant of 3 +/- 2% (sd) for the conversion of 17-hydroxyprogesterone to 11-deoxycortisol and of 5 +/- 3% for the conversion of progesterone to 11-deoxycorticosterone. The A434V mutant had a residual enzyme activity of 14 +/- 2% for 17-hydroxyprogesterone and 12 +/- 6% for progesterone. Substrate affinity was similar in the mutants as in the CYP21 wild-type protein, whereas reaction velocity was markedly decreased in both mutants. These effects could be readily explained by structural changes induced by the mutations, which were rationalized by a three-dimensional-model structure of the CYP21 protein. We hypothesize that the I77T mutation markedly decreases the reaction product release and/or substrate entrance to the enzyme's active site, whereas the A434V mutant reduces both the catalytic capacity and reaction velocity. Studying the enzyme function in vitro helps to understand the phenotypical expression and disease severity of 21-hydroxylase deficiency and also provides new insights into cytochrome P450 structure-function relationships.

    Full Text Available There is ample historical verification of 46,XX congenital adrenal hyperplasia (CAH patients being born with essentially male genitaliawhile outcome information is scant. Prior to glucocorticoid therapy, most patients died very young from adrenal insufficiency. Most available reports from laterchildhood, contain little information concerning sexual identity. Reports on older individuals lack adequate information about sexual identity and quality of life. The difficulty in assessing the relative impact of multiple dynamic environmental factors on the development of sexual identity, self- and body esteem and overall adjustment to life is clear. Nevertheless, it remains unclear whether those infants whose masculine genitalia at birth resulted in an initial male assignment would have enjoyed a better adult outcome had they been allowed to remain male rather than the female reassignment that most received. Further, one could ask whether a male sex of rearing should be considered in 46,XX CAH infants with male external genitalia. After reviewing available literature, we conclude that because those extremely virlized 46,XX CAH patients who were reared male with healthy social support demonstrated satisfactory levels of social and sexual function as adults a male sex assignment should be considered in these types of infants when social and cultural environment are supportive.

    Full Text Available Background: Congenital adrenal hyperplasia (CAH is an inherited recessive disorder of adrenal steroidogenesis. The enzymes most commonly affected are 21-hydroxylase. Past reports suggested brain magnetic resonance imaging (MRI abnormalities in CAH patients, affecting white matter signal, temporal lobe and amygdala structure and function. Aims: In the present study, we aimed to investigate the frequency of white matter changes and temporal lobes structures dysgenesis in a population of patients having CAH due to 21-hydroxylase deficiency. Materials and Methods: Neurological examination and brain MRI were performed in 26 patients. Results: Neurological examination revealed mental retardation in three patients, tremor in two patients, tendon reflexes asymmetry in one patient, and cerebellar syndrome in one patient. Eleven patients (42.3% showed MRI abnormalities: Eight of them had white matter hyperintensities, one patient had moderate atrophy in the right temporal, and hippocampal dysgenesis was found in the remaining two patients. Conclusions: Brain MRI abnormalities in CAH patients include white matter hyperintensities and temporal lobe structures dysgenesis. The mechanisms involved seem related to hormonal imbalances during brain development and exposure to excess exogenous glucocorticoids. Clinical implications of such lesions remain unclear. More extensive studies are required to define better the relationships between brain involvement and different CAH phenotypes and treatment regimens.

    In newborn infants, normal adrenal glands are characterized by a relatively thin echogenic center surrounded by a thick, hypoechoic cortical rim as seen on ultrasound (US). Various disorders involving the neonatal adrenal gland include adrenal hemorrhage, hyperplasia, cyst, Wolman's disease, and congenital neuroblastoma. Adrenal hemorrhage is the most common cause of an adrenal mass in the neonate, though differentiation between adrenal hemorrhage and neuroblastoma is in many cases difficult. We describe characteristic US, CT and MR imaging findings in neonates with various adrenal disorders.

    Newborn screening for congenital adrenal hyperplasia (CAH) is performed by measuring the concentration of 17α-hydroxyprogesterone (17-OHP) in dried blood spots. Unfortunately, the level of 17-OHP varies due to multiple factors, and therefore, the false positive rate for the test is a challenge. We analyzed screening data from 2007 to 2015 to determine the effect of seasonal changes and manufacturer kit lot changes on 17-OHP values and on numbers of infants referred. Data from screening 2.2 million infants over a 9-year period indicates that in the NYS during the colder months, daily mean 17-OHP values are higher, more retests are performed, and more infants are referred even though fewer infants are born. The practice of using fixed cutoffs for referring infants for CAH leads to more false positive results in colder months. In addition, there was an overall 10% increase in the daily mean 17-OHP values from the 2 years before and after a manufacturer kit lot change that occurred in November 2013, suggestive of a functional change in the kit at that time.

    While reports showing a link between prenatal androgen exposure and human gender role behavior are consistent and the effects are robust, associations to gender identity or cross-gender identification are less clear. The aim of the current study was to investigate potential cross-gender identification in girls exposed prenatally to high concentrations of androgens due to classical congenital adrenal hyperplasia (CAH). Assessment included two standardized measures and a short parent interview assessing frequency of behavioral features of cross-gender identification as conceptualized in Part A of the diagnostic criteria for gender identity disorder (GID) in the DSM-IV-TR. Next, because existing measures may have conflated gender role behavior with gender identity and because the distinction is potentially informative, we factor analyzed items from the measures which included both gender identity and gender role items to establish the independence of the two constructs. Participants were 43 girls and 38 boys with CAH and 41 unaffected female and 31 unaffected male relatives, aged 4- to 11-years. Girls with CAH had more cross-gender responses than female controls on all three measures of cross-gender identification as well as on a composite measure of gender identity independent of gender role behavior. Furthermore, parent report indicated that 5/39 (12.8 %) of the girls with CAH exhibited cross-gender behavior in all five behavioral domains which comprise the cross-gender identification component of GID compared to 0/105 (0.0 %) of the children in the other three groups combined. These data suggest that girls exposed to high concentrations of androgens prenatally are more likely to show cross-gender identification than girls without CAH or boys with and without CAH. Our findings suggest that prenatal androgen exposure could play a role in gender identity development in healthy children, and may be relevant to gender assignment in cases of prenatal hormone disruption

    We assessed core gender identity, sexual orientation, and recalled childhood gender role behavior in 16 women and 9 men with CAH and in 15 unaffected female and 10 unaffected male relatives, all between the ages of 18 and 44 years. Women with congenital adrenal hyperplasia (CAH) recalled significantly more male-typical play behavior as children than did unaffected women, whereas men with and without CAH did not differ. Women with CAH also reported significantly less satisfaction with the female sex of assignment and less heterosexual interest than did unaffected women. Again, men with CAH did not differ significantly from unaffected men in these respects. Our results for women with CAH are consistent with numerous prior reports indicating that girls with CAH show increased male-typical play behavior. They also support the hypotheses that these women show reduced heterosexual interest and reduced satisfaction with the female sex of assignment. Our results for males are consistent with most prior reports that boys with CAH do not show a general alteration in childhood play behavior. In addition, they provide initial evidence that core gender identity and sexual orientation are unaffected in men with CAH. Finally, among women with CAH, we found that recalled male-typical play in childhood correlated with reduced satisfaction with the female gender and reduced heterosexual interest in adulthood. Although prospective studies are needed, these results suggest that those girls with CAH who show the greatest alterations in childhood play behavior may be the most likely to develop a bisexual or homosexual orientation as adults and to be dissatisfied with the female sex of assignment.

    Gender assignment of children with intersexuality and related conditions has recently become highly controversial. On the basis of extensive animal research and a few human case reports, some authors have proposed the putative masculinization of the brain by prenatal hormones-indicated by the degree of genital masculinization-as the decisive criterion of gender assignment and have derived the recommendation that 46,XX newborns with congenital adrenal hyperplasia (CAH) and full genital masculinization should be assigned to the male gender. The purpose of this study was to test in CAH girls of middle childhood the assumption that prenatal androgens determine the development of gender identity. Fifteen girls with CAH (range of genital Prader stage, 2-4/5), 30 control girls, and 16 control boys (age range, 5-12 years) underwent 2 gender-play observation sessions, and a gender identity interview yielding scales of gender confusion/dysphoria. About half a year earlier, mothers had completed 2 questionnaires concerning their children's gender-related behavior. The results showed that, as expected, CAH girls scored more masculine than control girls on all scales measuring gender-related behavior, with robust effect sizes. By contrast, neither conventionally significant differences nor trends were found on the 3 scales of the gender identity interview. We conclude that prenatal androgenization of 46,XX fetuses leads to marked masculinization of later gender-related behavior, but the absence of any increased gender-identity confusion/dysphoria does not indicate a direct determination of gender identity by prenatal androgens and does not, therefore, support a male gender assignment at birth of the most markedly masculinized girls.

    The mitochondrial benzodiazepine receptor (mBzR) appears to be a key factor in the flow of cholesterol into mitochondria to permit the initiation of steroid hormone synthesis. The mBzR consists of three components; the 18-kDa component on the outer mitochondrial membrane appears to contain the benzodiazepine binding site, and is hence often termed the peripheral benzodiazepine receptor (PBR). Using a cloned human PBR cDNA as probe, we have cloned the human PBR gene. The 13-kb gene is divided into four exons, with exon 1 encoding only a short 5' untranslated segment. The 5' flanking DNA lacks TATA and CAAT boxes but contains a cluster of SP-1 binding sites, typical of "house-keeping" genes. The encoded PBR mRNA is alternately spliced into two forms: "authentic" PBR mRNA retains all four exons, while a short form termed PBR-S lacks exon 2. While PBR-S contains a 102-codon open reading frame with a typical initiator sequence, the reading frame differs from that of PBR, so that the encoded protein is unrelated to PBR. RT-PCR and RNase protection experiments confirm that both PBR and PBR-S are expressed in all tissues examined and that expression PBR-S is about 10 times the level of PBR. Expression of PBR cDNA in pCMV5 vectors transfected into COS-1 cells resulted in increased binding of [3H]PK11195, but expression of PBR-S did not. It has been speculated that patients with congenital lipoid adrenal hyperplasia, who cannot make any steroids, might have a genetic lesion in mBzR. RT-PCR analysis of testicular RNA from such a patient, sequencing of the cDNA, and blotting analysis of genomic DNA all indicate that the gene and mRNA for the PBR component of mBzR are normal in this disease.

  6. Adrenal gland and bone.

    Hardy, Rowan; Cooper, Mark S

    The adrenal gland synthesizes steroid hormones from the adrenal cortex and catecholamines from the adrenal medulla. Both cortisol and adrenal androgens can have powerful effects on bone. The overproduction of cortisol in Cushing's disease leads to a dramatic reduction in bone density and an increase risk of fracture. Overproduction of adrenal androgens in congenital adrenal hyperplasia (CAH) leads to marked changes in bone growth and development with early growth acceleration but ultimately a significant reduction in final adult height. The role of more physiological levels of glucocorticoids and androgens on bone metabolism is less clear. Cortisol levels measured in elderly individuals show a weak correlation with measures of bone density and change in bone density over time with a high cortisol level associated with lower bone density and more rapid bone loss. Cortisol levels and the dynamics of cortisol secretion change with age which could also explain some age related changes in bone physiology. It is also now clear that adrenal steroids can be metabolized within bone tissue itself. Local synthesis of cortisol within bone from its inactive precursor cortisone has been demonstrated and the amount of cortisol produced within osteoblasts appears to increase with age. With regard to adrenal androgens there is a dramatic reduction in levels with aging and several studies have examined the impact that restoration of these levels back to those seen in younger individuals has on bone health. Most of these studies show small positive effects in women, not men, but the skeletal sites where benefits are seen varies from study to study.

    Even with current so called physiologic doses of glucocorticoid replacement therapy, children with congenital adrenal hyperplasia (CAH) often show relative short stature and delayed bone maturation, an observation that suggests possible long-term effects on bone metabolism of daily transient post-absorptive hypercortisolemia. In 28 patients with 21-hydroxylase or 17 alpha-hydroxylase deficiency (16 females and 12 males, ages 4.9-22 yr) who had received oral cortisol 10-15 mg/M2/day for 4.7-22 yr, we studied cortisol bioavailability, growth, bone maturation, vertebral bone mineral density, and various markers of bone formation and resorption. Patients were grouped according to mean on-therapy serum 170H-progesterone or progesterone levels as tight control (170HP 40 nmol/L). There was no difference in peak post-absorptive serum cortisol or area under the concentration-time curve, and only three patients had a peak serum cortisol of more than 700 nmol/L. There was no difference in present height Z-score (-0.96; -0.24; -0.6), height Z-score at age 2 yr (-1.5; +0.4; -1.3), or current growth velocity Z-score (-0.1; +1.2; -2.2) between the groups, but bone maturation Z-score was significantly delayed (-1.63) in the tight control group and advanced (+0.8) in the poor control group. Present height was highly correlated (r = 0.8) with height at age 2 yr. Serum calcium, phosphorus, alkaline phosphatase, parathormone, and 25OH-vitamin D levels were all normal. There was no difference between the groups in age-corrected vertebral bone mineral density, and no difference in serum osteocalcin, procollagen peptide, or collagen C-terminal telopeptide, nor in urinary amino-terminal telopeptide. The data suggest that current methods of cortisol replacement do not significantly influence bone formation, resorption or density during childhood and therefore should not contribute to adult osteoporosis. The possibility remains that hypercortisolemia during infancy produces the short

    Adrenocortical insufficiency may arise through primary failure of the adrenal glands or due to lack of ACTH stimulation as a result of pituitary or hypothalamic dysfunction. Prolonged administration of exogenous steroids will suppress the hypothalamic-pituitary-adrenal axis, and hence cortisol secretion. We review briefly the causes, investigation, and treatment of adrenal insufficiency, and highlight aspects of particular relevance to patients with adrenal tumors.

    The large hyperaemic foetal adrenal gland is vulnerable to vascular damage. This may occur in the neonatal period as a consequence of difficult labour, or its aetiology may not be apparent. The spectrum of presentation is considerable, ranging from asymptomatic to severe life-threatening intra-abdominal haemorrhage. The presentation of adrenal insufficiency may be delayed but the regenerative capacity of the adrenal is great, and most adrenal haemorrhage is not associated with significantly impaired function. Some reports showed that cholestatic hepatopathy with congenital hypopituitarism reversed by hydrocortisone treatment is considered in the context of the endocrine syndrome, probably as a consequence of the adrenal failure. We describe a case of bilateral adrenal haemorrhage with hepatitis syndrome and persistent hypoglycaemia in a newborn male with striking features of neonatal cholestasis and adrenal crisis.

    Congenital myopathies are a clinically and genetically heterogeneous group of muscle disorders characterized by congenital or early-onset hypotonia and muscle weakness, and specific pathological features on muscle biopsy. The phenotype ranges from foetal akinesia resulting in in utero or neonatal mortality, to milder disorders that are not life-limiting. Over the past decade, more than 20 new congenital myopathy genes have been identified. Most encode proteins involved in muscle contraction; however, mutations in ion channel-encoding genes are increasingly being recognized as a cause of this group of disorders. SCN4A encodes the α-subunit of the skeletal muscle voltage-gated sodium channel (Nav1.4). This channel is essential for the generation and propagation of the muscle action potential crucial to muscle contraction. Dominant SCN4A gain-of-function mutations are a well-established cause of myotonia and periodic paralysis. Using whole exome sequencing, we identified homozygous or compound heterozygous SCN4A mutations in a cohort of 11 individuals from six unrelated kindreds with congenital myopathy. Affected members developed in utero- or neonatal-onset muscle weakness of variable severity. In seven cases, severe muscle weakness resulted in death during the third trimester or shortly after birth. The remaining four cases had marked congenital or neonatal-onset hypotonia and weakness associated with mild-to-moderate facial and neck weakness, significant neonatal-onset respiratory and swallowing difficulties and childhood-onset spinal deformities. All four surviving cohort members experienced clinical improvement in the first decade of life. Muscle biopsies showed myopathic features including fibre size variability, presence of fibrofatty tissue of varying severity, without specific structural abnormalities. Electrophysiology suggested a myopathic process, without myotonia. In vitro functional assessment in HEK293 cells of the impact of the identified SCN4A

    Full Text Available La Hiperplasia Suprarrenal Congénita o Síndrome Adrenogenital es un cuadro clínico poco frecuente. Las anomalías que presenta van asociadas a síndromes que a veces son muy complejos, destacando, entre otros, el seudohermafroditismo femenino y el hermafroditismo verdadero. Las mujeres que la padecen presentan como alteración más evidente un clítoris aumentado de tamaño (megaloclítoris y otras alteraciones en los genitales externos. Ante estas pacientes es necesario realizar un diagnostico correcto mediante exploración física y otras pruebas complementarias: estudios genéticos, analíticos, hematológicos y urinarios. La corrección quirúrgica del megaloclítoris es necesaria no sólo para mejorar el aspecto de los genitales externos, sino también para que tanto la paciente como su familia se encuentren menos afectados psicológicamente. Existen varias técnicas quirúrgicas que intentan corregir esta malformación, como la amputación o clitorectomía total, la retroposición o enterramiento y la clitorectomía parcial selectiva. Todas ellas, junto con otras correcciones de los genitales externos afectados, han sido utilizadas hasta el día de hoy. Presentamos el caso de una paciente con Hiperplasia Suprarrenal Congénita por déficit del enzima 21-hidroxilasa. Describimos su clínica, la técnica quirúrgica aplicada en su caso y, sobre todo, dado la rareza de esta patología, comunicamos que, tras dos embarazos, los dos hijos nacidos, no presentaron la alteración congénita materna.Congenital Adrenal Hyperplasia is a rare patology, whith clinical expressions like female pseudohermaphroditism or true hermaphroditism.

    Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder that usually results from paternally and maternally transmitted mutations in genes for steroidogenic enzymes. Recent studies on steroid 21-hydroxylase deficiency, the most common form of CAH, have revealed that a small percentage of patients have a non-carrier parent; uniparental disomy (UPD) and de novo mutations were reported as disease-causing mechanisms in these patients. However, it remains unknown whether UPD and de novo mutations underlie other forms of CAH. Here, we report a male patient with steroid 11β-hydroxylase deficiency (11OHD) born to a non-carrier mother. The patient was identified by an elevated 17-hydroxyprogesterone level at a neonatal mass-screening test. His clinical features were comparable to those of previously reported patients with 11OHD. Direct sequencing of CYP11B1 identified a homozygous IVS7+1G>A mutation in the patient, which was not shared by his mother. Comparative genomic hybridization of the patient detected UPD of chromosome 8 [UPD(8)]. Microsatellite analysis indicated non-maternal origin of the UPD(8) and confirmed parentage of other chromosomes. This study shows for the first time that 11OHD can be caused by UPD in the presence of a non-carrier parent. Awareness of such rare cases should improve the accuracy of genetic counseling for families with CAH. Our data support the importance of UPD as an underlying mechanism of autosomal recessive disorders.

Results Total 44 patients (23 male and 21 female) aged from 7 days to 14 years were included. Five cases of the patients had family history. All of the patients were showing hyperpigmentation and virilisation when diagnosed. The females were found to have enlarged clitoris. Some of the enlarged clitoris looked like penis,some also had inferior vigina fissure.Some patients had no vaginal orifice. Also some of the females had merged labium major with the appearance of scrotum. Meanwhile,the males were found to have enlarged penis and even to be associated with erection or spermatorrhea. The change of voice happened even at 3 - 5 years of age. The growth rate was sped up and therefore they were usually taller than their peers. According to the symptoms and whether being accompanied by hyporatremia, hyperkalemia and(or) acidosis,the included children were diagnosed as follows:17 simple -virilising cases,26 virilising and salt -wasting cases and a non- classical case.

    Classic findings have demonstrated an important role for sex steroids as regulators of aggression, but this relationship is lacking within some environmental contexts. In mammals and birds, the adrenal androgen dehydroepiandrosterone (DHEA), a non-gonadal precursor of biologically active steroids, has been linked to aggression. Although females, like males, use aggression when competing for limited resources, the mechanisms underlying female aggression remain understudied. Here, we propose a previously undescribed endocrine mechanism regulating female aggression via direct action of the pineal hormone melatonin on adrenal androgens. We examined this in a solitary hamster species, Phodopus sungorus, in which both sexes are highly territorial across the seasons, and display increased aggression concomitant with decreased serum levels of sex steroids in short 'winter-like' days. Short- but not long-day females had increased adrenal DHEA responsiveness co-occurring with morphological changes in the adrenal gland. Further, serum DHEA and total adrenal DHEA content were elevated in short days. Lastly, melatonin increased DHEA and aggression and stimulated DHEA release from cultured adrenals. Collectively, these findings demonstrate that DHEA is a key peripheral regulator of aggression and that melatonin coordinates a 'seasonal switch' from gonadal to adrenal regulation of aggression by direct action on the adrenal glands.

    Human adrenal development is a complex and relatively poorly understood process. However, significant insight into some of the mechanisms regulating adrenal development and function is being obtained through the analysis of individuals and families with adrenal hypoplasia. Adrenal hypoplasia can occur: (1) secondary to defects in pituitary adrenocorticotropin (ACTH) synthesis, processing and release (secondary adrenal hypoplasia; e.g. HESX1, LHX4, SOX3, TPIT, pituitary POMC, PC1); (2) as part of several ACTH resistance syndromes (e.g. MC2R/ACTHR, MRAP, Alacrima, Achalasia, Addison disease), or as (3) a primary defect in the development of the adrenal gland itself (primary adrenal hypoplasia; e.g. DAX1/NR0B1 - dosage-sensitive sex reversal, adrenal hypoplasia congenita critical region on the X chromosome 1). Indeed, the X-linked form of primary adrenal hypoplasia due to deletions or mutations in the orphan nuclear receptor DAX1 occurs in around half of male infants presenting with a salt-losing adrenal crisis, where no obvious steroidogenic defect (e.g. 21-hydroxylase deficiency), metabolic abnormality (e.g. neonatal adrenoleukodystrophy) or physical cause (e.g. adrenal haemorrhage) is found. Establishing the underlying basis of adrenal failure can have important implications for investigating associated features, the likely long-term approach to treatment, and for counselling families about the risk of other children being affected.

    Adrenal insufficiency is defined by impaired secretion of adrenocortical hormones. It is classified upon the etiology in primary and secondary. Rapid recognition and therapy of adrenocortical crisis are critical to survival. Patients often have nonspecific symptoms: anorexia, vomiting, weakness, fatigue and lethargy. They are followed by hypotension, shock, hypoglicemia, hyponatremia and hyperkalemia. All patients with adrenal insufficiency require urgent fluid reposition, correction of hypoglycemia and glucocorticoid replacement, in order to avoid serious consequences of adrenal crisis. After initial crisis treatment, maintenance dose of corticoids should be indicated. Mineralocorticoids replacement, if necessary, should also be initiated.

    An understanding of the embryology of the adrenal glands is necessary to appreciate the location of adrenal ectopic, or rest, tissue which can occur anywhere along the course of gonadal descent. This tissue usually has no clinical significance, but may become hyperplastic in patients with primary or secondary adrenal pathology. In congenital adrenal hyperplasia, hyperplastic rest tissue may present as a soft-tissue mass, particularly in the gonads and retroperitoneum, and may be mistaken for tumour. The adrenal in the neonate is proportionately much larger than in the adult; in renal ectopy or agenesis the ipsilateral adrenal is normally sited and may be mistaken for a kidney because of its size. This review article illustrates the embryology of the adrenal with particular emphasis on the relevance of embryology to pathology.

    Objective To investigate the clinical effects of early diagnosis and treatment for the patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD). Methods Sixty-nine CAH patients who were born from June 1997 to March 2011 and diagnosed and treated within 6 months after birth, were enrolled to investigate the clinical effects of early treatment on growth and development of patients, and to explore the key evaluation indicators for the patients' follow-up. Results The median age of start of treatment was 47 days (4 to 180 days) after birth. The average growth velocity of 96 patients was (7.4±1.1) cm/y. The median age at the last visit was 3.4 (0.67-9.92) years old; the average height was within the 25th-50th percentile of normal children; 76% patients had normal bone age. The predicted final height was (168.9±8.5) cm in male patients and (155.4±8.0) cm in females respectively, with about 71% within their genetic target heights, which was superior to the predicted final height (151.0±7.0) cm in the patients diagnosed and treated after 1 year old in previous report. The incidence of central precocious puberty was 5.79% (4/69), lower than that in previous report of the patients treated when they were either less than 3 years old (14%) or over 3 years old (50%). During the treatment, the proportion of the patients with normal levels of electrolyte, ACTH and testosterone was 86%-93%, but there was a large fluctuation in 17-OH progesterone. ACTH was positively correlated with both 17-OH progesterone and testosterone. Conclusions Early diagnosis and treatment for patients with CAH could improve their growth and bone development, reduce the incidence of precocious puberty and achieve better final height.%目的 探讨先天性肾上腺皮质增生症(CAH,21-羟化酶缺乏)早期治疗的疗效.方法 回顾性分析1997年至2011年出生,在6月龄内诊断并开始治疗的69例CAH患儿病史资料,了解早期治疗对患儿生长

At each visit,roentgenograms of the hands and wrists were taken,fasting peripheral blood were collected to test serum dehydroepiandrosterone sulfate, progesterone, 17-hydroxyprogesterone ( 17-OHP ),androstenedione ( △4-A ),testosterone,free testosterone,estrone,and estradiol concentrations at 8AM in the morning before the first dose of glucocorticoid.Then the patients were classified as being in " Good Control" or in " Poor Control" based on clinical criteria including signs of androgen excess,growth velocity and bone age increment at each interval. Comparisons were carried out between the serum steroid concentrations of the two groups. The receiver operating characteristic (ROC) curves were used to determine the cut-off values for diagnosing "Poor Control".Result Both of serum △4-A and 17-OHP concentrations were higher in " Poor Control" group than those in " Good Control" group [5.95(2.23-11.2) nmoL/Lversus 1.05(1.05-9.89) nmoL/L,t =2.19;13.85(6.06-20) μg/Lversus 3.67(0.42- 21.1) μg/L,t =2.17; P < 0.05,respectively]. The ROC curves for serum △4-Aconcentrations,serum 17-OHP concentrations,serum △4-A in combination with 17-OHP concentrations were constructed with areas under the ROC curves (95% CI) of 0.76(0.62,0.90),0.75(0.62,0.88),0.69 (0.54,0.84),P < 0.05,respectively.Serum △4-A of 3.9 nmol/L had 0.78 of sensitivity and 0.75 of specificity in diagnosing "Poor Control".Serum 17-OHP of 7.1 μg/L has 0.67 of sensitivity and 0.71 of specificity in diagnosing "Poor Control".Conclusion Each of serum 17-OHP or/and △4-A concentration was of significance

  16. Adrenal insufficiency: diagnosis and management.

    Science.gov (United States)

    Munver, Ravi; Volfson, Ilya A

    2006-01-01

    Adrenal insufficiency is a disorder characterized by hypoactive adrenal glands resulting in insufficient production of the hormones cortisol and aldosterone by the adrenal cortex. This disorder may develop as a primary failure of the adrenal cortex or be secondary to an abnormality of the hypothalamic-pituitary axis. Patients with adrenal insufficiency often are asymptomatic or they may present with fatigue, muscle weakness, weight loss, low blood pressure, and sometimes darkening of the skin. The presentation of adrenal insufficiency varies dramatically and poses a major diagnostic dilemma. This review focuses on the diagnosis and treatment of primary and secondary adrenal insufficiency.

    Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

    Full Text Available The ideal surgical technique and appropriate age for performing feminizing genitoplasty are debatable, and few long-term outcome studies have been reported. PURPOSE: To report a retrospective study on anatomical and functional outcomes of feminizing genitoplasty in patients with virilizing congenital adrenal hyperplasia. METHODS: We selected 34 patients (mean age = 3.4 ± 2.5 yr with genital ambiguity classified according to Prader stage. Follow-up ranged from 2 to 16 years. Clitoral length ranged from 1.9 to 5.0 cm; 28 patients had a single perineal orifice, and 6 had a double orifice. The surgical technique included clitorovaginoplasty in a single procedure and was carried out before 2 years of age in 18 patients. Clitoroplasty was performed with glans preservation in all patients. Blood supply was exclusively maintained by the frenular pedicle in 97% of the cases, whereas clitoral dorsal nerves and vessels were preserved in the remaining 3%. The opening of the urogenital sinus was performed using either the Y-V perineal flap procedure (25 patients or the cut-back incision procedure (8 patients. RESULTS: Good morphological and functional results were achieved in 68% of the patients; 21% of the patients had surgical complications, such as incision bleeding (2 cases, glans necrosis (1 girl with Prader V, and vaginal introitus stenosis (4 cases. Three of the latter underwent dilation with acrylic molds in the post-pubertal period with good functional results. CONCLUSIONS: We conclude that single-stage feminizing genitoplasty consisting of vulvoplasty, clitoroplasty, and Y-V perineal flap produced good cosmetic and functional results in virilized girls with congenital adrenal hyperplasia, with few complications. In addition, this surgical approach prevented the need for neovaginaplasty even in patients with high vaginal insertion.OBJETIVO: Apresentar um estudo retrospectivo sobre os resultados cosméticos e funcionais da genitoplastia feminizante

    We report the postmortem findings of two siblings with gross and microscopic features consistent with IMAGe association (Intrauterine growth retardation, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital anomalies) with an emphasis on the histopathology of the adrenal gland in this rare syndrome. The first sibling was an 8-week old male diagnosed postnatally with primary adrenal insufficiency. There was no deletion of the DAX1 gene by FISH. Examination at autopsy revealed dysmorphic features including frontal bossing, epicanthal folds, flat philtrum, cryptorchidism, penile chordee, overriding fourth toe, and height and weight below 3rd percentile. Grossly, the adrenal glands were not identified; however, microscopic examination of the suprarenal soft tissue revealed a 3 mm focus of disorganized fetal adrenal cortex with distended "cytomegalic" cells with abundant pink eosinophilic cytoplasm, vesicular nuclei, and cytoplasmic vacuolization. A minute focus of permanent adult cortex was also seen, but no adrenal medulla was identified. An autopsy of the sibling, who died 12 years previously at day 9 of life, revealed dysmorphic facial features with cryptorchidism and a large phallus. The adrenal glands were grossly hypoplastic (11 mm). Histologically, the adrenal glands showed disorganized fetal cortex with cytomegalic cells, a larger amount of permanent adult cortex, and bizarre nuclei with numerous pseudoinclusions. While there is currently limited information regarding the histopathologic adrenal findings in IMAGe association, our small case series suggests overlapping features between X-linked recessive congenital adrenal hypoplasia (cytomegalic cells with lack of permanent adult cortex) and autosomal recessive congenital adrenal hypoplasia (diminished permanent adult cortex without cytomegalic cells).

    Full Text Available Pure androgen-secreting adrenal adenoma is very rare, and its diagnosis remains a clinical challenge. Its association with resistant hypertension is uncommon and not well understood. We present an 18-year-old female with a 10-year history of hirsutism that was accidentally diagnosed with an adrenal mass during the evaluation of a hypertensive crisis. She had a long-standing history of hirsutism, clitorimegaly, deepening of the voice, and primary amenorrhea. She was phenotypically and socially a male. FSH, LH, prolactin, estradiol, 17-hydroxyprogesterone, and progesterone were normal. Total testosterone and DHEA-S were elevated. Cushing syndrome, primary aldosteronism, pheochromocytoma, and nonclassic congenital adrenal hyperplasia were ruled out. She underwent adrenalectomy and pathology reported an adenoma. At 2-month followup, hirsutism and virilizing symptoms clearly improved and blood pressure normalized without antihypertensive medications, current literature of this unusual illness and it association with hypertension is presented and discussed.

  2. Genetic Causes in Adrenal or Ovarian Hyperandrogenism in the Reproductive Years

    2009-01-01

    Full Text Available Hyperandrogenism and androgenisation frequently occur within families so that a monogenic cause such as congenital adrenal hyperplasia (CAH must be considered. For the most part, classical CAH is first diagnosed and treated on the basis of common sex development disorders in early childhood by pediatric endocrinologists. In contrast, the non-classic "late-onset CAH" is mostly symptomatic by androgenisation from the age of puberty. For both forms, the final diagnosis relies on the evidence of a CYP21 gene mutation. Even though the incidence of CAH in newborns with a ratio of 1:5000 is rare, the frequency of heterozygotes in central Europe is relatively prevalent with 1:50. In patients with hyperandrogenism of adrenal origin who desire children, a CYP21 mutation should therefore be excluded. In case of a known mutation carrier, the CYP21 gene diagnostic also should be applied on the partner. If both partners are genetic carriers, a dexamethasone (DEX therapy of the pregnant woman should be considered very early in each case immediately after determining a pregnancy to prevent serious virilization of the external genitalia of female CAH fetuses. A common differential diagnosis is androgenisation through ovarian hyperandrogenism. For many years, candidate genes for the polycystic ovary syndrome (PCOS have been investigated. The search focuses on genes involved in the regulation of insulin, follicle maturation as well as androgen secretion and regulation. Especially promising is a gene polymorphism on chromosome 19p13.2 in association with insulin resistance and disordered β-cell functions. Examinations of polymorphisms in FSH receptor genes make one expect that the effective gonadotropin dose in ovarian stimulation can be individually determined before treatment. Thus, severe hyperstimulation syndromes in PCOS patients possibly can be avoided. One might anticipate that new results in molecular genetic PCOS research in the upcoming years will lead

  3. Preliminary report: effect of adrenal androgen and estrogen on bone maturation and bone mineral density.

    To clarify the independent physiological roles of adrenal androgen and estrogen on bone growth, we compared the lumbar spine bone mineral density (BMD) in prepubertal girls with virilizing congenital adrenal hyperplasia (CAH) (n = 17) and girls with central precocious puberty (CPP) (n = 18). When BMD was analyzed according to chronologic age, no significant differences were found between CPP and CAH patients. However, when adjusted to bone age, BMD was statistically higher in CAH than in CPP subjects. This finding suggests that adrenal androgen, as well as estrogen, plays an important role in increasing BMD. Adrenal androgen may act on bone not only as androgen, but as estrogen after having been metabolized into an aromatized bone-active compound in peripheral tissues, such as bone and fat. Therefore, adrenal androgen may have a more important role in increasing BMD than previously realized.

    Adrenal scintillation scanning, CT and ultrasonography are compared with the conventional imaging methods. The accuracy of retroperitoneal pneumography and adrenal venography are not high, and they detected only large tumors such as Cushing's syndrome and pheochromocytoma. Scintillation scanning is highly effective for the diagnoses of primary aldosteronism and Cushing's syndrome. However, this technique does not visualize pheochromocytoma or hypopituitarism. CT is noninvasive and of high diagnostic value. It is impossible to diagnose tumors by ultrasonography unless the size is more than 3 cm.

    Congenital adrenal hyperplasia (CAH) is a group of disorders affecting the adrenal steroid synthesis. The most common form, 21-hydroxylase deficiency (21-OHD), leads to decreased production of cortisol and aldosterone with increased androgen secretion. In classic CAH, glucocorticoid treatment can be life-saving and serves to bring the symptoms under control. However, the treatment challenge is to effectively control the excess androgen effect by using the lowest possible glucocorticoid dose. Previous studies suggested a relationship between ovarian cyst formation and adrenal androgen excess, but neonatal large ovarian cysts have been very rarely reported in newborns with CAH. Here, we present the unique case of a neonate with classical 21-OHD who underwent surgery for a giant (10x8x7 cm) unilateral solitary ovarian follicular cyst on the 2nd postnatal day. Hormonal evaluation of the patient revealed high-dose hook effect for serum testosterone levels for the first time by a two-site immunoradiometric assay. Possible mechanisms by which androgen excess may cause ovarian cyst formation are discussed. Conflict of interest:None declared. PMID:22664361

    The past decade has seen significant advances in our understanding of the genetic aetiology of several forms of adrenal failure that present in infancy or childhood. Several of these disorders affect adrenal development and are termed 'adrenal hypoplasia'. These conditions can be broadly divided into: (1) secondary forms of adrenal hypoplasia due to panhypopituitarism (e.g. HESX1, LHX4, SOX3) or abnormalities in ACTH synthesis (TPIT) or processing (e.g. POMC or PC1); (2) adrenal hypoplasia as part of an ACTH resistance syndrome [MC2R/ACTH receptor, MRAP, AAAS (triple A syndrome)], and (3) primary defects in the development of the adrenal gland itself (primary adrenal hypoplasia). Primary adrenal hypoplasia most commonly occurs in an X-linked form due to mutations in the nuclear receptor DAX1 (NR0B1) but can occur in a poorly understood recessive form or as part of the IMAGe (intrauterine growth retardation, metaphyseal dysplasia, adrenal hypoplasia, genitourinary anomalies) syndrome. Defining the molecular basis of these conditions can have significant clinical implications for management, counselling and presymptomatic diagnosis, as well as providing fascinating insight into normal and abnormal mechanisms of adrenal development in humans.

    Congenital thrombophilia is a thrombotic diathesis caused by a variety of genetic abnormalities in blood coagulation factors or their inhibitory factors associated with physiological thrombus formation. Patients with congenital thrombophilia often present with unusual clinical episodes of venous thrombosis (occasionally combined with pulmonary embolism, known as venous thromboembolism) at a young age and recurrence in atypical vessels, such as the mesenteric vein and superior sagittal sinus, often with a family history of this condition. Studies in Japan as well as in western countries have shown congenital thrombophilia to be caused by a wide variety of genetic abnormalities in natural anticoagulant proteins, such as antithrombin, protein C, and protein S. However, there may still be many unknown causes of hereditary thrombosis. We recently reported a case of hereditary thrombosis induced by a novel mechanism of antithrombin resistance, that is, congenital thrombophilia caused by a gain-of-function mutation in the gene encoding the coagulation factor prothrombin.

    Purpose. To evaluate the diagnosis and treatment of adrenal incidentalomas. Methods. One hundred and twenty-six patients with incidentalomas were analyzed, among them 98 underwent operation. Results. Eighty-eight of the adrenal incidentalomas were discovered by ultrasound. Of all the types of adrenal incidentalomas, 52 (41.3%) of them were adenomas; 43 (34.1%) were hypersecretory adrenal tumors, including 29 pheochromocytomas, 9 primary aldosteronisms, 1 adrenogenitol syndrome combined with adrenal adenoma, 2 Cushing's syndrome combined with adenomas and 2 Cushing's syndrome combined with nodular hyperplasias. All nonhypersecretory adrenal adenomas were under 6 cm, and all adrenal carcinomas were above 6 cm.Conclusions. To search for hypersecretory adrenal tumors and to detect malignant adrenal tumors are quite essential in the process of diagnosing adrenal incidentalomas. For nonhypersecretory adrenal adenomas, the size of tumor is the most important index in determining whether the tumor is benign or malignant and whether the tumor needs to be treated with operation.

    In contrast to the sophisticated music processing reported in the general population, individuals with congenital amusia show deficits in music perception and production. Congenital amusia occurs without brain damage, sensory or cognitive deficits, and has been suggested as a lifelong deficit with genetic origin. Even though recognized for a long time, this disorder has been systematically studied only relatively recently for its behavioral and neural correlates. The currently most investigated hypothesis about the underlying deficits concerns the pitch dimension, notably with impaired pitch discrimination and memory. Anatomic and functional investigations of pitch processing revealed that the amusic brain presents abnormalities in the auditory and inferior frontal cortices, associated with decreased connectivity between these structures. The deficit also impairs processing of pitch in speech material and processing of the time dimension in music for some of the amusic individuals, but does not seem to affect spatial processing. Some studies suggest at least partial dissociation in the disorder between perception and production. Recent studies revealed spared implicit pitch perception in congenital amusia, supporting the power of implicit cognition in the music domain. Current challenges consist in defining different subtypes of congenital amusia as well as developing rehabilitation programs for this "musical handicap."

    2016-05-01

    The pituitary adrenocorticotropic hormone (ACTH) plays a pivotal role in homeostasis and stress response and is thus the major component of the hypothalamo-pituitary-adrenal axis. After a brief summary of ACTH production from proopiomelanocortin (POMC) and on ACTH receptor properties, the first part of the review covers the role of ACTH in steroidogenesis and steroid secretion. We highlight the mechanisms explaining the differential acute vs chronic effects of ACTH on aldosterone and glucocorticoid secretion. The second part summarizes the effects of ACTH on adrenal growth, addressing its role as either a mitogenic or a differentiating factor. We then review the mechanisms involved in steroid secretion, from the classical Cyclic adenosine monophosphate second messenger system to various signaling cascades. We also consider how the interaction between the extracellular matrix and the cytoskeleton may trigger activation of signaling platforms potentially stimulating or repressing the steroidogenic potency of ACTH. Finally, we consider the extra-adrenal actions of ACTH, in particular its role in differentiation in a variety of cell types, in addition to its known lipolytic effects on adipocytes. In each section, we endeavor to correlate basic mechanisms of ACTH function with the pathological consequences of ACTH signaling deficiency and of overproduction of ACTH.

    To determine the adrenal contribution to elevated plasma androgens in 31 young hyperandrogenemic women with acne and/or hirsutism, we compared their responses to ACTH with those of 14 normal women. Each subject was given a low dose (10 micrograms/m2) of synthetic ACTH-(1-24) (Cortrosyn) after administration of 1.5 mg dexamethasone the night before the test. Thirty and 60 min responses of plasma 17 alpha-hydroxypregnenolone (17-Preg), 17 alpha-hydroxyprogesterone, (17-prog), dehydroepiandrosterone (DHEA), androstenedione, 11-deoxycortisol, and cortisol were measured. Eighteen (58%) patients had increased responses of at least one 17-ketosteroid or adrenal androgen precursor. All patients had cortisol responses within the range of those of the 14 normal subjects. Nine patients (29%) had evidence of steroid biosynthetic enzyme deficiencies, either mild congenital adrenal hyperplasia or the heterozygote state; after ACTH, 4 of these patients had elevated 17-prog in the range of values in heterozygote carriers of 21-hydroxylase deficiency, 2 had elevated levels of 11-deoxycortisol compatible with 11 beta-hydroxylase deficiency, and 3 had elevated levels of 17-Preg and DHEA, suggestive of 3 beta-hydroxysteroid dehydrogenase deficiency. Another 9 subjects (29%) had 17-ketosteroid (DHEA and/or androstenedione) hyperresponsiveness to ACTH with associated elevated 17-Preg responses. As a group, their patterns suggested relatively deficient 3 beta-hydroxysteroid dehydrogenase and relatively hyperactive C lyase without impairment of cortisol secretion. This pattern resembles exaggerated adrenarche, and we postulate that these 9 patients have hyperplasia of the zona reticularis. Neither basal levels of plasma androgens (free testosterone and DHEA sulfate) nor menstrual history predicted which patients would have abnormal ACTH responses. Although 5 of 11 (45%) patients with acne alone had abnormal responses to ACTH, 10 of 14 patients with acne and hirsutism (71%) had abnormal

    Full Text Available Adrenal incidentalomas are clinical dilemmas for the clinicians. The work up, to differentiate between malignant and benign lesions, and hyperfunctioning and nonfunctioning lesions is mandatory before the consideration of surgical resection. Ectopic thyroid tissue located in the adrenal gland (ETTAG is a very rare condition. We report a case of ETTAG presenting with adrenal incidentaloma. A 57-year-old woman was admitted with incidental right adrenal mass. Hormone evaluation showed no hormonal activity. Magnetic resonance imaging revealed a 20x17 mm lobulated solid mass, which contained millimetric hypointense nodular areas consistent with calcifications. Loss of signal intensity on out-of-phase could not be evaluated because of the calcifications. Right adrenalectomy was performed to establish the histopathological diagnosis and to rule out malignancy. Histopathological diagnosis revealed ETTAG. Her medical history was positive for multinodular goiter and bilateral subtotal thyroidectomy 32 years ago. Thyroid ultrasonography showed residual thyroid tissue in both the right and left lobes, and colloid thyroid nodules. Fine needle aspiration biopsy from the nodules revealed benign nodules. The patient has been followed up for six years, and no change in thyroid nodule sizes and no evidence of metastatic foci have been detected. ETTAG would be considered in the differential diagnosis of adrenal mass showing no hormonal activity, especially when magnetic resonance images are not consistent with adrenal adenoma. Long follow-up duration of this case suggests that it was a benign condition.

    Adrenal incidentalomas are a heterogeneous group of pathological entities, including benign or malignant adrenocortical or medullary tumors, hormonally active or inactive lesions, which are identified incidentally during the examination of nonadrenal-related abdominal complaints. About 1.5% to 23% of adrenal incidentalomas are pheochromocytomas. Composite pheochromocytoma is a rare tumour of adrenal medulla with divergente clinical course. This type of pheochromocytoma is designated "composite" or "mixed," depending on whether pheochromocytoma and nonpheochromocytoma components show the same embryologic origin. Nonpheochromocytoma components found in the composite pheochromocytoma include ganglioneuroma, ganglioneuroblastoma, neuroblastoma, and malignant schwannoma. The biologic behavior of composite pheochromocytomas may be as difficult to predict as more traditional pheochromocytomas; based on the number of cases reported to date the presence of areas resembling ganglioneuroblastoma or neuroblastoma does not necessary indicate a poor prognosis. Some may behave in a malignant fashion with metastasis by a component of the tumour which has neural features. Pheochromocytomas and paragangliomas are well-defined entities. Some of their nonsporadic associations and unusual morphological appearances are not universally appreciated. We report on a rare association of left adrenal CP, with typical right adrenal phochromocytoma and retroperitoneal paraganglioma, and a review of literature. We analyzed the clinical and immunohistochemical features in a 24-year-old woman with composite pheochromocytoma localized in the left adrenal gland and associated with blood pressure of 200/140 mmHg. Abdominal computed tomography and 131-J MIBG revealed a 65 x 60 mm mass in the right adrenal gland, but no revealed 45 x 40 mm retroperitoneal mass and 20 x 20 mm mass in the left adrenal region. Serum and urinary adrenaline levels were high, and catecholamine levels in the blood sample of

    Iatrogenic adrenal insufficiency is a potential harmful side effect of treatment with corticosteroids. It manifests itself when an insufficient cortisol response to biological stress leads to an Addisonian crisis: a life-threatening situation. We describe a case of a patient who developed an Addisonian crisis after inappropriate discontinuation of budesonide (a topical steroid used in Crohn's disease) treatment. Iatrogenic adrenal insufficiency due to budesonide use has been rarely reported. Prescribers should be aware of the resulting risk for an Addisonian crisis.

    There are several types of hydrocephalus, which are characterized based on the location of the cerebrospinal fluid (CSF) accumulation. Physical features of animals with congenital hydrocephalus may include a dome-shaped skull, persistent fontanelle, and bilateral ventrolateral strabismus. Medical therapy involves decreasing the production of CSF. The most common surgical treatment is placement of a ventriculoperitoneal shunt. Postoperative complications may include infection, blockage, drainage abnormalities, and mechanical failure.

    @@ Platelets are essential for normal hemostasis.Platelets adhere to damaged blood vessels, and then aggregate and promote activation of coagulation factors, resulting to ceasing bleeding.Both quantitative and qualitative abnormalities of platelets can cause bleeding problems.Among them, immune thrombocytopenias are the most common conditions.However, congenital thrombocytopenias are often neglected because of their relative rarity and complex laboratory tests.That causes misdiagnosis and unnecessary and potentially harmful treatments for many patients.

    Since testes and adrenal cortex derive from the same urogenital ridge, adrenal tissue with descending gonads may migrate in early embryonic period. Although most often ectopic tissue undergoes atrophy in some cases, when adrenocorticotrophic (ACTH) overstimulation occurs, the adrenal remnants in the testes may become hypertrophic and form testicular adrenal rest tumors (TARTs). The growth of TARTs in the testes leads to obstruction of the seminiferous tubules which can mechanically impair the function of the gonads and cause irreversible azoospermia. We describe a patient suffering since neonatal period from congenital adrenal hyperplasia (CAH), disorder with defected pathway of cortisol production, which leads to increased ACTH production and to overstimulation of adrenal cortex. He had very poor disease control and therefore in late puberty he was diagnosed with TARTs. At the age of 19.5 he was diagnosed with azoospermia, most likely caused by TARTs. It is the first evidence of TARTs in Polish literature. Although not many cases have been published so far the incidence of TARTs seems to be highly underdiagnosed, so it seems reasonable to consider the disease in differential diagnosis of male infertility.

    In recent years, marked increase in incidence of congenital syphilis has occurred throughout the world due to changes in social norms and development of penicillin-resistant strains. Early diagnosis plays an important role in congenital syphilis as the clinical manifestations may simulate many other conditions in the paediatric age group. The authors analyzed 52 cases of congenital syphilis admitted to the department of paediatrics, Chosun University Hospital, clinically and radiologically. Among them, 18 cases were born in this hospital and 34 cases were admitted from OPD, during the period of 8 years from January, 1975 to December, 1982. The results obtained were as follows; 1. In 28 of 34 cases (82%), the first clinical manifestations were below the age of 3 months. 2. Among the 52 cases, a male predominance was observed with a male to female ratio of 2 : 1. 3. The serologic test (VDRL) of the 52 studied cases showed reactive response in 49 cases (94%), and that of syphilitic mothers except 6 cases, reactive in all studied cases. 4. The major manifestations of the 52 cases were bone tenderness (12%) and swelling of the joints (7%) in skeletal system, hepatosplenomegaly (79%) and skin lesions (73%) in extraskeletal one. 5. The radiological skeletal changes were detected in 45 of 52 cases (87%), and the commonest findings were detected in 45 of 52 cases (87%), and the commonest findings were metaphysitis (83%) and periostitis (81%). The most characteristic type of metaphysitis were transverse trophic line (74%) and zone of rarefaction (65%). 6. The commonest bones to be affected were growing metaphyses of the long bones, particulary about the wrist and the knee. The order of frequency were radius (80%), uina (80%), tibia (77%), femur (69%) and humerus (40%)

    Congenital hypoaldosteronism due to an isolated aldosterone biosynthesis defect is rare. We report a 4 month old female infant who presented with failure to thrive, persistent hyponatremia and hyperkalemia. Investigations revealed normal serum 17 hydroxy progesterone and cortisol. A decreased serum aldosterone and serum 18 hydroxy corticosterone levels with a low 18 hydroxy corticosterone: aldosterone ratio was suggestive of corticosterone methyl oxidase type I deficiency. She was started on fludrocortisone replacement therapy with a subsequent normalization of electrolytes. Further molecular analysis is needed to ascertain the precise nature of the mutation.

    Postoperative bilateral adrenal hemorrhage is a rare but potentially life-threatening complication. This diagnosis is often missed because the symptoms and laboratory results are usually nonspecific. We report a case of bilateral adrenal hemorrhage associated with acute primary adrenal insufficiency following laparoscopic cholecystectomy. The knowledge of this uncommon complication following any abdominal surgery allows timey diagnosis and rapid treatment.

    Adrenal insufficiency (AI) is a rare endocrine disease, associated to increased mortality if left untreated. It can be due to a primary failure of the adrenal glands (primary AI) or malfunctioning of the hypothalamic-pituitary-adrenal axis (HPA) (secondary AI). The lack of data on incidence/prevalence of adrenal insufficiency in Spain complicates any evaluation of the magnitude of the problem in our country. Initial symptoms are non-specific, so often there is a delay in diagnosis. Current therapy with available glucocorticoids is associated with decreased quality of life in patients with treated AI, as well as with increased mortality and morbidity, probably related to both over-treatment and lack of hydrocortisone, associated with non-physiological peaks and troughs of the drug over the 24 hours. The availability of a new drug with a modified dual release (immediate and retarded), that requires one only daily dose, improves and simplifies the treatment, increases compliance as well as quality of life, morbidity and possibly mortality. This revision deals with the knowledge on the situation both globally and in Spain, prior to the availability of this new drug.

    Sometimes in the course of care in a neonatal intensive care unit, there may be a rush to intervene in cases where limited intervention is actually the correct course. One such example is that of neonatal adrenal hemorrhage. We present the case of a male term neonate with shock, metabolic acidosis, distended abdomen, and falling hematocrit. His prenatal and delivery histories were uneventful except for a nuchal cord. Apgar scores were 9 and 9. Because of his dramatic presentation, certain members of the medical team suggested immediate surgical intervention. However, a calm and careful evaluation revealed the true diagnosis and course of action. Ultrasound of the abdomen showed a mass between the liver and kidney, but the origin was difficult to identify. A computed tomography scan supported the diagnosis of right adrenal hemorrhage. His serum cortisol level was normal. The patient was managed conservatively and discharged home after a 1-week stay in the hospital. Subsequent abdominal ultrasound showed resolving adrenal hemorrhage with minimal calcification. A review of the pertinent literature is presented. Physicians should remember adrenal hemorrhage when evaluating a newborn infant with shock, acidosis, abdominal distention, and falling hematocrit and that conservative management is usually indicated.

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    2015-01-01

    Adrenal - renal fusion is a rare entity defined as incomplete encapsulation of the adrenal gland and kidney with histologically adjacent functional tissue. This report describes the first published intraoperative identification of this anomaly during laparoscopic adrenalectomy. The patient was a 59-year-old man with chronic hypertension refractory to multiple antihypertensives found to be caused by a right-sided aldosterone-producing adrenal adenoma in the setting of bilateral adrenal hyperplasia. During laparoscopic adrenalectomy, the normal avascular plane between the kidney and adrenal gland was absent. Pathologic evaluation confirmed adrenal - renal fusion without adrenal heterotopia. Identified intraoperatively, this may be misdiagnosed as invasive malignancy, and thus awareness of this anomaly may help prevent unnecessarily morbid resection. PMID:26195881

    Full Text Available Heart failure (HF is a chronic clinical syndrome characterized by the reduction in left ventricular (LV function and it represents one of the most important causes of morbidity and mortality worldwide. Despite considerable advances in pharmacological treatment, HF represents a severe clinical and social burden. Sympathetic outflow, characterized by increased circulating catecholamines (CAs biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers are presently being investigated for the treatment of this disease. Adrenal gland secretes Epinephrine (80% and Norepinephrine (20% in response to acetylcholine stimulation of nicotinic cholinergic receptors on the chromaffin cell membranes. This process is regulated by adrenergic receptors (ARs: α2ARs inhibit CA release through coupling to inhibitory Gi-proteins, and βARs (mainly β2ARs stimulate CA release through coupling to stimulatory Gs-proteins. All ARs are G-protein-coupled receptors (GPCRs and GPCR kinases (GRKs regulate their signaling and function. Adrenal GRK2-mediated α2AR desensitization and downregulation are increased in HF and seem to be a fundamental regulator of CA secretion from the adrenal gland. Consequently, restoration of adrenal a2AR signaling through the inhibition of GRK2 is a fascinating sympatholytic therapeutic strategy for chronic HF. This strategy could have several significant advantages over existing HF pharmacotherapies (antiadrenergic, such as bAR-blockers minimizing side-effects on extra-cardiac tissues and reducing the chronic activation of the renin–angiotensin–aldosterone and endothelin systems.The role of adrenal ARs in regulation of sympathetic hyperactivity opens interesting perspectives in understanding pathophysiology of HF and identifying new potential therapeutic targets.

    Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of malignant lymphoma. Although the involvement of adrenal glands in IVLBCL is often observed, primary adrenal IVLBCL is rare. Most reported cases of adrenal IVLBCL showed bilateral lesions resulting in rapidly progressive adrenal failure and poor prognosis. Here, we report a case of slowly progressive primary adrenal IVLBCL manifesting initially with unilateral adrenal incidentaloma. This case is a silent IVLBCL and shows that the enlargement of both adrenal glands can be followed.

    The nuclear receptor transcription factors DAX-1 (NR0B1) and SF-1 (NR5A1) regulate many aspects of adrenal and reproductive development and function. Disruption of the genes encoding these factors can be associated with pediatric adrenal disease. DAX-1 mutations are classically associated with X-linked adrenal hypoplasia congenita, hypogonadotropic hypogonadism and impaired spermatogenesis. However, other phenotypes are also being reported, such as isolated mineralocorticoid insufficiency, premature sexual development, primary adrenal insufficiency in a 46, XX patient and late-onset X-linked adrenal hypoplasia congenita and/or hypogonadotropic hypogonadism. SF-1 mutations have also been associated with primary adrenal insufficiency, together with 46, XY disorders of sex development. However it is emerging that SF-1 changes are a relatively rare cause of primary adrenal failure in humans, and most individuals with SF-1 mutations have a spectrum of 46, XY disorders of sex development phenotypes. These conditions range from 46, XY females with streak gonads and müllerian structures, through children with ambiguous genitalia and inguinal testes, to severe penoscrotal hypospadias with undescended testes. Therefore, the human gonad appears to be more sensitive than the adrenal gland to loss of SF-1 function. This review will focus on the expanding range of phenotypes associated with DAX-1 and SF-1 mutations.

    We report a rare case of bilateral primary adrenal non-Hodgkin's lymphoma with adrenal failure. A 66-year-old woman developed symptoms of adrenal failure. The cause of adrenal failure was suspected to be malignant lymphoma based on the high levels of serum soluble interleukin-2 receptor and LDH. Bilateral adrenalectomy was performed and pathological examination showed intravascular large B-cell lymphoma (IVL). Although complete remission was achieved, recurrence occurred three months later with brain metastases. IVL should be suspected in patients with bilateral adrenal tumors who present with rapidly progressive adrenal failure.

    Full Text Available Objective To investigate the imaging and clinicopathological features of pachygyria limited in the right temporo-parieto-occipital lobe and the key points of its diagnosis and treatment, in order to improve the recognition of this disease.  Methods and Results A 2-year-old boy was admitted to hospital because of paroxysmal loss of consciousness and convulsion for 18 months with progressive aggravation. MRI showed malformations of cortical development in the right temporo-parieto-occipital lobe. Epileptic foci resection on the right temporo-parieto-occipital lobe was made. Histological examination after operation showed uneven thickening of gray matter, shrinking of white matter and disappearing cortical stratification, while a lot of dysmorphic neurons, balloon cells and scattered balloon cells in white matter appeared. Immunohistochemical staining revealed that dysmorphic neurons were positive for non-phosphorylated neurofilament protein SMI-32, microtubule-associated protein-2 (MAP-2 and vimentin (Vim or neurofilament protein (NF. Both dysmorphic neurons and balloon cells expressed phosphorylated ribosomal S6 protein (RPS6, while the former was stronger than the latter. Balloon cells were not positive for MAP-2 or Vim. No disturbance of consciousness or limb twitches occurred in this patient during one-year follow-up.  Conclusions Congenital pachygyria was cortical dysplasia caused by the early proliferation and migration disorder of brain, and should be distinguished with focal cortical dysplasia (FCD type Ⅱ b and tuberous sclerosis complex (TSC. Clinical history, imaging and histological features should be included in the diagnosis. DOI: 10.3969/j.issn.1672-6731.2016.02.005

    2015-01-01

    Full Text Available Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50 mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

    2012-01-01

    Background and Objectives: Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. Methods: Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. Results: Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5×3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. Conclusion: Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

    1986-05-01

    Fifty-seven patients with primary non-adrenal malignancy were found to have unsuspected adrenal abnormality on CT. In 33, comparison of histophatologic findings and/or the patients' hospital course or follow-up lead to the diagnosis of adrenal metastases (23), benign non-functioning adenomas (7), metastasis with hyperplasia (1), benign hyperplasia (1), and fatty infiltration (1). The analysis of CT findings indicated that: I) A heterogenous adrenal mass showing contrast enhancement was always metastatic, II) Nonfunctioning adenomas were always 3 cm or smaller in diameter, III) Bilateral adrenal masses and growth of adrenal mass on follow-up CT or regression on treatment indicated metastases, and IV) metastatic disease could not be excluded purely on the basis of the size of the adrenal mass.

    2015-03-01

    Adrenal insufficiency continues to be a challenge for patients, their physicians, and researchers. During the past decade, long-term studies have shown increased mortality and morbidity and impaired quality of life in patients with adrenal insufficiency. These findings might, at least partially, be due to the failure of glucocorticoid replacement therapy to closely resemble physiological diurnal secretion of cortisol. The potential effect of newly developed glucocorticoid drugs is a focus of research, as are the mechanisms potentially underlying increased morbidity and mortality. Adrenal crisis remains a threat to lives, and awareness and preventative measures now receive increasing attention. Awareness should be raised in medical teams and patients about adrenal insufficiency and management of adrenal crisis to improve clinical outcome.

    2013-01-01

    Full Text Available Context: The adrenal gland is a common site for neoplastic diseases and primary adrenal lymphoma (PAL is a rare tumor with around 120 cases reported so far. Case Report: We present a rare case of 76-year-old male who presented with headache, confusion, inappropriate body movements and abdominal pain. Adrenal biopsy revealed PAL and he has had an excellent neurologic outcome to date with chemotherapy and involved field radiation. Conclusion: The majority of cases of PAL are B cell lymphomas with diffuse large cell in 70% of cases. Clinical symptoms are variable and patients may present with abdominal pain, fever, anorexia, weight loss, fatigue or symptoms of adrenal insufficiency. Therapeutic modalities for PAL include surgery, chemotherapy and radiotherapy and corticosteroid replacement. With this case report, we hope to raise awareness about this rare disease and to include lymphoma in the differential of adrenal masses.

  4. A case of human intramuscular adrenal gland transplantation as a cure for chronic adrenal insufficiency.

    Science.gov (United States)

    Grodstein, E; Hardy, M A; Goldstein, M J

    2010-02-01

    Intramuscular endocrine gland transplantation has been well described as it pertains to parathyroid autotransplantation; however, transplantation of the adrenal gland is less well characterized. While adrenal autotransplantation in the setting of Cushing's disease has been described, intramuscular adrenal allotransplantation as a cure for adrenal insufficiency to our knowledge has not been previously carried out. Current treatment for adrenal insufficiency leaves patients without diurnal variation in cortisol release and susceptible to the detrimental effects of chronic hypercortisolism. We describe here the case of a 5-year-old girl with renal failure who had adrenal insufficiency following fulminant meningococcemia that led to requirements for both stress-dose steroid and mineralocorticoid replacement. Ten months after the onset of her disease, she received a simultaneous renal and adrenal gland transplant from her mother. The adrenal gland allograft was morselized into 1 mm(3) segments and implanted into three 2 cm pockets created in her rectus abdominis muscle. Three years after surgery, her allograft remains fully functional, responding well to adrenocorticotropin hormone stimulation and the patient does not require any steroid or mineral-corticoid supplementation. We believe this case represents the first description of successful functional intramuscular adrenal allograft transplantation with long-term follow up as a cure for adrenal insufficiency.

    2003-02-01

    In untreated congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHDS) the presence of adrenal and testicular tumors had been described; however little is known about the effect of the enzymatic defect on fertility in males. We studied a male adult patient affected by 21OHDS for infertility, after a long period of discontinuation of glucocorticoid therapy and then during resumption of treatment and 8 months after monoadrenalectomy. The initial spermatic count revealed azoospermia and testicular needle aspiration showed a cytological picture consistent with prepuberty. The morphofunctional study revealed a right adrenal mass with reduced uptake at radioscan. Treatment was resumed with onset of impotency, which improved after reduction of the dose of glucocorticoids. The patient was monoadrenalectomised and his spermatic count increased. The patient shows that corticosteroid therapy in 21OHDS should be continued lifelong to avoid adrenal hyperplasia with possible areas of autonomy and to allow regular fertility. Impotence during treatment is probably due to a decrease of excessive adrenal androgens while testicular androgen production is still suppressed.

  7. [Classical taxomomies].

    2006-01-01

    The sequence of classic paradigms in taxonomy that partly replaced each other and partly co-exist is given as follows: the theory of "organ and organism similarity", the naturalistic theory, the descriptive theory, and the phylogenetic theory. The naturalistic classics accepted the notion of "the plan of creation". The rejection of appealing to this plan brought forth certain problems in the formulation of the purpose of taxonomy; these problems were differently solved by the descriptive and the phylogenetic classic traditions. The difficulties of the current paradigms arising from the loss of a "strong purpose", a problem to be solved by taxonomists that is to be clear and interesting to a wide range of non-professionals. The paradox of formalization led to the losing of content of the methods due to their formalization. To attract attention to taxonomy, a new "image of the results" of its work that would be interesting to the non-professionals is necessary. The co-existence of different methods of reseach applied to different groups of facts leads to the loss of integrity of the research. It is not only that the taxon becomes a hypothesis and such hypotheses multiply. The comparison of these hypotheses is problematic, because each of them is supported by its own independent scope of facts. Because of the existence of a fundamental meronotaxonomic discrepancy, taxonomic systems based on different groups of characters appear to be incomparable, being rather systems of characters than systems of taxa. Systems of characters are not directly comparable with each other; they can be compared only through appealing to taxa, but taxa themselves exist only in the form of a number of hypotheses. Consequently, each separate taxonomic approach creates its own nature, its own subject of research. Therefore, it is necessary to describe the subject of research correctly (and indicate the purpose of research), as well as to distinguish clearly between results achieved through

    2012-01-01

    Full Text Available Intravascular large B-cell lymphoma (IVLBCL is a rare subtype of malignant lymphoma. Although the involvement of adrenal glands in IVLBCL is often observed, primary adrenal IVLBCL is rare. Most reported cases of adrenal IVLBCL showed bilateral lesions resulting in rapidly progressive adrenal failure and poor prognosis. Here, we report a case of slowly progressive primary adrenal IVLBCL manifesting initially with unilateral adrenal incidentaloma. This case is a silent IVLBCL and shows that the enlargement of both adrenal glands can be followed.

    2002-10-01

    Adrenal lesions in children may present with an asymptomatic adrenal mass lesion, an endocrinopathy, a hypertensive or metabolic crisis or a paraneoplastic syndrome. Some of the underlying disease processes remain localised within the adrenal gland or may develop into disseminated disease. The role of the radiologist is to confirm the adrenal location of a lesion and to document any other foci of disease. Ultrasound, CT, MR imaging and metaiodobenzylguanidine scintigraphy are the most commonly utilised imaging modalities for examining the adrenal glands and their pathologies in children. This paper reviews the spectrum of adrenal disease in childhood and presents the information as a series of radiological appearances: anomalies of adrenal shape, location, number and size, cystic adrenal masses, solid adrenal mass lesions, and adrenal calcifications are all examined. The radiological findings must always be interpreted in conjunction with the patient's age, the clinical history, the findings on physical examination and the available biochemical data. (orig.)

    Full Text Available Background. Adrenal collision tumors (ACTs, in which distinct tumors coexist without intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, pheochromocytoma, or metastatic malignant tumor. Case Report. A 32-year-old woman who had been experiencing gastric discomfort for one month was referred to our hospital with abnormal imaging findings. The physical examination and the laboratory data including endocrine studies were unremarkable. Abdomen computed tomography (CT and magnetic resonance imaging (MRI showed two adjacent masses in the left suprarenal fossa, and a laparoscopic left adrenalectomy was done. Histological and immunohistochemical (IHC examinations revealed two distinct tumors: a pigmented adrenal cortical oncocytoma (ACO and a ganglioneuroma, respectively. Conclusion. Both tumors are rare in the adrenal gland and exist as ACTs only exceptionally rarely. This is the first reported case of coexisting oncocytoma and ganglioneuroma in the same adrenal gland to our knowledge.

    Full Text Available Adrenal histoplasmosis is an uncommon cause for adrenal insufficiency. The duration of treatment for adrenal histoplasmosis is not clear. Existing treatment regimens advocate antifungals given for periods ranging from 6 months to 2 years.

Here, we present a case of bilateral adrenal histoplasmosis in an immunocompetent, 62-year-old gentleman from Texas along with a brief review of the published literature. Given the risk of patient decompensation secondary to adrenal insufficiency and the wide availability of effective treatments, adrenal histoplasmosis must be considered even in immunocompetent adults who acquire adrenal masses.

  17. A case of adrenal Cushing’s syndrome with bilateral adrenal masses

    2016-05-01

    Full Text Available A functional lesion in corticotrophin (ACTH-independent Cushing’s syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and 131I-6β-iodomethyl-19-norcholesterol (131I-NP-59 scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (<5pg/mL. No suppression was observed in both the low- and high-dose dexamethasone suppression tests. Adrenal computed tomography revealed bilateral adrenal masses. Adrenal venous sampling was performed, and the right-to-left lateralisation ratio was 14.29. The finding from adrenal scintigraphy with NP-59 was consistent with right adrenal adenoma. The patient underwent laparoscopic right adrenalectomy, and the pathology report showed adrenocortical adenoma. Her postoperative cortisol level was 3.2μg/dL, and her Cushingoid appearance improved. In sum, both adrenal venous sampling and 131I-NP-59 scintigraphy are good diagnostic methods for Cushing’s syndrome presenting with bilateral adrenal masses.

    Full Text Available Secondary involvement of the adrenal gland with non-Hodgkin’s lymphoma has been reported to occur in up to 25% of patients during the course of the disease. A 45-year-old man presented with a several month history of nausea, fatigue and weight loss. His medical history was unremarkable. Abdominal computed tomography (CT was performed and showed bilateral adrenal massive masses measuring 10x7.5 cm on the left and 4.8x4 cm on the right. He developed adrenal insufficiency in the follow-up period. The patient was started on replacement dose of prednisolone. A positron emission tomography-CT scan was acquired for further staging of the disease and showed intense fluorodeoxyglucose accumulation in both adrenal glands, additionally a slight fluorodeoxyglucose accumulation was observed in the ileocecal site. He did not accept adrenal biopsy or surgery. Histopathological examination of the ileocecal site revealed diffuse large B-cell lymphoma. He was administered rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy. Bilateral adrenal lymphoma is a rare entity when compared with the incidence of adenoma and adrenal metastases of other cancers. Adrenal insufficiency may be the primary symptom of presentation, especially with bilateral involvement as in bilateral adrenal lymphoma.

    The disturbance of the hypothalamic-pituitary- adrenal axis characteristic of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is likely to affect brain development, yet neuroanatomic work is only beginning. Fetal hyperandrogenemia in 46, XX 21-OHD leads to masculinized brain organization and, consequently, at later stages of development, to masculinized gender-related behavior and cognitive function, including, although relatively uncommonly, gender identity. Genital masculinization as well as its surgical treatment has implications for social stigmatization and sexual functioning. CAH-associated electrolyte crises in infancy and later may result in severe cognitive impairment. Psychiatric disorders are somewhat increased, especially in patients with severe degrees of CAH.

    Levy-Shraga, Y; Pinhas-Hamiel, O

    2014-12-01

    Adrenal insufficiency (AI) is a rare disease in childhood and adolescence that results from disruption in the hypothalamic-pituitary-adrenal axis. Pediatricians should be familiar with this entity since acute adrenal crisis is a life-threatening condition that requires immediate treatment. In the early stages of AI, the clinical manifestations may be subtle and non-specific; thus, they are frequently unrecognized. The main therapeutic approach in all forms of adrenal insufficiency is glucocorticoid replacement; the dose should be titrated appropriately to avoid under or overtreatment. Patient and family education is particularly important, to enable adjustment of dosage replacement therapy during stress and to prevent crisis. This article summarizes the current knowledge of AI and provides new insights on its management in children.

    Adrenal hemorrhage (AH) is a well-described complication of the neonatal period, anticoagulant therapy, and overwhelming bacterial infection especially with N. meningitis. Until recently the diagnosis of acute AH was based predominantly on autopsy findings. Ultrasound and computed tomography examinations have been successfully used for antemortem detection of AH in neonates and anticoagulated patients. We report two patients with fulminant meningococcal infection who demonstrated bilateral adrenal hemorrhages on ultrasonography.

  7. Metabolism of adrenal cholesterol in man

    Science.gov (United States)

    Borkowski, Abraham; Delcroix, Claude; Levin, Sam

    1972-01-01

    The synthesis of adrenal cholesterol, its esterification and the synthesis of the glucocorticosteroid hormones were studied in vitro on human adrenal tissue. It was found that the synthesis of adrenal cholesterol may normally be small in the zona “fasciculata,” particularly when compared with the synthesis of the glucocorticosteroid hormones, that it is several times higher in the zona “reticularis” where esterified cholesterol is less abundant, and that under ACTH stimulation it increases strikingly and proportionally to the degree of esterified adrenal cholesterol depletion. On the other hand, the relative rate of esterification as well as the concentration of free adrenal cholesterol are remarkably stable: they do not differ according to the adrenal zonation and are unaffected by ACTH. Furthermore, from a qualitative point of view, the relative proportions of Δ1 and Δ2 cholesteryl esters formed in situ are similar to those anticipated from their relative concentrations, suggesting that the characteristic fatty acid distribution of the adrenal cholesteryl esters results from an in situ esterification rather than from a selective uptake of the plasma cholesteryl esters. Besides, the in vitro esterification reveals a propensity to the formation of the most unsaturated cholesteryl esters. Regarding hydrocortisone and corticosterone, their synthesis tends to be more elevated in the zona “fasciculata.” Despite its higher cholesterol concentration the zona “fasciculata” should not therefore be viewed as a quiescent functional complement to the zona “reticularis” and the cortical distribution of glucocorticosteroid hormone synthesis is quite distinct from that of adrenal cholesterol synthesis.

    Full Text Available Adrenal myelolipomas are rare benign tumors of the adrenal cortex composed of adipose and hematopoietic cells. They have been postulated to arise from repeated stimulation by stress, inflammation and ACTH oversecretion. Myelolipomas are usually detected incidentally on imaging and do not require any active intervention besides regular follow-up by imaging. However, myelolipomas may insidiously grow to large sizes and cause mass effects and hemorrhage. Timely diagnosis and surgical resection are curative and lifesaving.

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    Introduction: Adrenal disorders could be a life-threatening emergency, hence requires immediate therapeutic management. For this awareness regarding its diagnosis, management, and treatment is prime important. Aims and Objective: To study the awareness of adrenal disorders among interns and postgraduates students of Hamidia Hospital, Bhopal. Materials and Methods: A cross-sectional questionnaire-based study was performed. Fifty-six participants, i.e., 1st, 2nd, and 3rd years postgraduate residents of general medicine (n = 14 × 3) and interns (n = 14) were included in the study. There were 12 questions on adrenal insufficiency, adrenal adenoma, congenital adrenal hyperplasia (CAH), nonclassical CAH (NCCAH), pheochromocytoma, and Conn's syndrome. One mark was awarded for each correct response. Results: In the present study, 14 (25%) participants scored < 5 marks, 33 (58.9%) scored between 6 and 9, and 9 (16.1%) scored between 10 and 12. The mean score among the participants was 6.38 ± 2.505, with a range from 2 to 11 marks. The number of correct answers by postgraduates residents of 1st year was 101, 2nd year was 95, and 3rd year was 93 and interns scored 68 out of total 168 questions in each group. Mean awareness score for residents of 1st, 2nd, 3rd years participants and interns was 7.21 ± 2.806, 6.79 ± 2.119, and 6.64 ± 2.818 and 6.63 ± 2.505, respectively. Most of the participants recorded correct responses related to diagnosis (57.7%) followed by responses related to treatment (64.3%). Answers to a question regarding how commonly is adrenal insufficiency diagnosed in medical Intensive Care Unit, none of the individuals responded correctly. Conclusion: There was a lack of awareness regarding diagnosis, management, and treatment of adrenal disorders in central India. We need to prioritize training related to these illnesses in our postgraduate teaching curriculum in practice. PMID:28217529

    Full Text Available Although lymphoma may occasionally involve the adrenal glands as part of a generalized disease process, primary adrenal lymphoma (PAL is a rare disease. We present a case of a 62-year-old woman with a history of mild/moderate hereditary spherocytosis with a well-compensated baseline haemoglobin, who presented with rapidly progressive symptomatic anaemia. During the diagnostic workup, imaging revealed bilateral large adrenal masses and she was later diagnosed with diffuse large B-cell non-Hodgkin’s lymphoma (DLBCL, with the adrenal glands being the dominant site of the disease. The patient was started on systemic chemotherapy, but her disease progressed with neurological involvement which responded to second-line therapy. Her adrenal disease however was refractory to further therapy.

    Congenital lobar emphysema is a rare disease, which is characterized by pulmoner hyperinflation. Depending on the degree of bronchial obstruction, the clinical presentation may be variable. We report a rare case with congenital lobar emphysema in a 38-days-old male infant who presented with severe respiratory distress and hypertension. Air trapping in the left upper lung and significant mediastinal shift to the right were observed on the chest x-ray. Emphysematous changes were detected on the thorax computed tomography and considered as congenital lobar emphysema. The upper left lobectomy was successfully performed by pediatric surgeons. On postoperative follow up, no sign of respiratory distress occurred and the patient was normotensive. In this report, a case with congenital lobar emphysema, which is a rare cause of respiratory distress and hypertension is discussed. PMID:27381542

    Full Text Available We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

    Full Text Available Abstract Introduction Many fetal malformations can occur because of maternal diabetes. However, ambiguous genital organs have never been reported as an associated finding in the literature. This is the first report of associated ambiguous genital organ and bilateral adrenal hyperplasia in a case of diabetic fetopathy. Case presentation A 19-year-old Thai primigravida with familial history of diabetes mellitus (DM was diagnosed as having gestational DM type 2, based on 100 g oral glucose tolerance test, and was poorly controlled with insulin injections. Delayed targeted ultrasonography at 28 weeks gestation revealed multiple fetal anomalies. The woman underwent low transverse cesarean section at 30 weeks gestation due to preterm labor and transverse lie. The newborn with ambiguous genitalia was delivered but expired after birth. Autopsy findings revealed alobar holoprosencephaly, a prominent forehead, hypotelorism, an absent nose, absent bilateral ears, median cleft lip and palate, preaxial polydactyly of the right hand, accessory spleens, single umbilical artery, markedly enlarged adrenal glands and ambiguous external genitalia The subsequent fetal chromosomal study revealed 46,XX. Conclusion We describe a case of diabetic fetopathy with classic facial malformation and preaxial hallucal polydactyly which has been proposed as a marker of diabetic embryopathy. Bilateral adrenal hyperplasia with ambiguous genitalia, an uncommon associated anomaly, was also identified. It is controversial whether adrenal hyperplasia can be a novel feature of diabetic fetopathy or just a coincidental finding. Further observation and adequate investigation are needed in such cases.

    Congenital diaphragmatic hernia is a congenital malformation of the diaphragm, resulting in the herniation of the abdominal organs into the thoracic cavity. The most common types of congenital diaphragmatic hernia are Bochdalek hernia (postero-lateral hernia), Morgagni hernia (anterior defect), and diaphragm eventration (abnormal displacement of part or all of an otherwise intact diaphragm into the chest cavity). Congenital diaphragmatic hernia is a life-threatening pathology in infants, and a major cause of death due to pulmonary hypoplasia and pulmonary hypertension. We present a fatal case of congenital diaphragmatic hernia in a newborn. At the autopsy, a central defect of the diaphragm was found, 8 × 5 cm in size, that led to a herniation of the small intestine, the right lobe of the liver, and the right adrenal gland into the thorax. An esophageal atresia was associated with the congenital diaphragmatic hernia. The lungs showed severe hypoplasia and atelectasia. Physicians should pay attention to a prenatal diagnosis of congenital diaphragmatic hernia in order to prevent newborn fatalities.

  4. The adrenal cortex and life.

    Science.gov (United States)

    Vinson, Gavin P

    2009-03-05

    The template for our understanding of the physiological role of the adrenal cortex was set by Hans Selye, who demonstrated its key involvement in the response to stress, of whatever origin, and who also introduced the terms glucocorticoid and mineralocorticoid. Despite this, from the late 1940s on there was certainly general awareness of the multiple actions of glucocorticoids, including effects on the thymus and immune system, cardiovascular system, water balance, and the CNS. For these reasons, and perhaps because in the early studies of the actions of individual steroids there was less clear-cut difference between them, there was some initial resistance to the use of these terms. Today they are universal and unchallenged. It can be argued that, with respect to the glucocorticoids, this term colours our perception of their physiological importance, and may be misleading. By taking evidence from disease states, emphasis is placed on extreme conditions that do not necessarily reveal normal physiology. In particular, evidence for the role of glucocorticoid regulation of gluconeogenesis and blood glucose in the normal subject or animal is inconclusive. Similarly, while highly plausible theories explaining glucocorticoid actions on inflammation or the immune system as part of normal physiology have been presented, direct evidence to support them is hard to find. Under extreme conditions of chronic stress, the cumulative actions of glucocorticoids on insulin resistance or immunocompromise may indeed seem to be actually damaging. Two well-documented and long recognized situations create huge variation in glucocorticoid secretion. These are the circadian rhythm, and the acute response to mild stress, such as handling, in the rat. Neither of these can be adequately explained by the need for glucocorticoid action, as we currently understand it, particularly on carbohydrate metabolism or on the immune system. Perhaps we should re-examine other targets at the physiological

    2015-09-01

    Full Text Available Primary adrenal insufficiency is defined by the impaired synthesis of adrenocortical hormones due to an intrinsic disease of the adrenal cortex. Determining its etiology is crucial to allow adequate long-term management and genetic counseling. We report the case of a male adolescent that presented in the neonatal period with adrenal crisis and received replacement therapy for primary adrenal insufficiency. During follow-up, adrenal hypoplasia congenita (AHC was suspected given his persistently raised adrenocorticotropic hormone levels, with markedly low 17-OH progesterone and androstenedione levels. DNA sequence analysis revealed a mutation in NR0B1 gene (c.1292delG, confirming the diagnosis. Delayed puberty and persistent low levels of gonadotropins led to testosterone replacement therapy. X-linked AHC is a rare cause of primary adrenal insufficiency and hypogonadotropic hypogonadism, related to mutations in NR0B1 gene. Despite its rarity, AHC should be considered in patients who present with primary adrenal failure, low levels of 17-OH progesterone and hypogonadotropic hypogonadism.

    With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or 'incidentaloma', has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. While most incidentalomas represent benign disease, typically an adenoma, the possibility of m alignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed. (author)

    Full Text Available Bilateral adrenal hemorrhage (BAH is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency.

    Pheochromocytomas are usually solid tumours. But it can present as cystic lesions in the adrenal gland. Cystic lesions in adrenal gland with hypertension needs attention to rule out pheochromocytoma. If ignored, it may lead to hypertensive emergency, multisystem crisis and death. Early diagnosis with biochemistry, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) of abdomen, proper functional imaging like Meta Iodo Benzyl Guanidine (MIBG) scan is essential. Proper preoperative preparation is important to prevent hypertensive crisis during and after surgery. We are reporting a case of cystic pheochromocytoma in a young male. PMID:28050427

    It is known that adrenal insufficiency is one of the complications in primary adrenal lymphoma, especially those with bilateral adrenal involvement. A 73-year-old man was referred for general fatigue and high fever to the nearest hospital. The patient was transferred to our hospital for evaluation of bilateral adrenal tumors and hyponatremia. He was diagnosed as having non-Hodgkin's lymphoma (NHL) with primaries arising in both adrenal glands. Primary adrenal lymphoma (PAL) is a rare extra-nodal NHL. Although an appropriate treatment of this disease has not been established, our case has demonstrated that the combination of rituximab and THP-COP chemotherapy could be administered, and that it improved clinical manifestations. This case raises the suggestion that malignant lymphoma should be suspected in patients with bilateral adrenal tumors that present with progressive adrenal insufficiency.

    Congenital cataract is a type of cataract that presents at birth or during early childhood, and it is one of the most easily treatable causes of visual impairment and blindness during infancy, with an estimated prevalence of 1-6 cases per 10,000 live births. Approximately 50% of all congenital cataract cases may have a genetic cause, and such cases are quite heterogeneous. Although congenital nuclear cataract can be caused by multiple factors, genetic mutation remains the most common cause. All three types of Mendelian inheritance have been reported for cataract; however, autosomal dominant transmission seems to be the most frequent. The transparency and high refractive index of the lens are achieved by the precise architecture of fiber cells and homeostasis of the lens proteins in terms of their concentrations, stabilities, and supramolecular organization. Research on hereditary congenital cataract has led to the identification of several classes of candidate genes that encode proteins such crystallins, lens-specific connexins, aquaporin, cytoskeletal structural proteins, and developmental regulators. In this review, we highlight the identified genetic mutations that account for congenital nuclear cataract.

    Full Text Available Patients with human immunodeficiency virus infection are known to have increased risk of various neoplasms, including Kaposi sarcoma, which classically involves the skin and mucosal locations. The anaplastic variant of Kaposi sarcoma is rare and poorly documented in the literature. It is characterised clinically by a more aggressive behaviour and increased metastatic potential, and histologically by increased cellularity, mitotic rate, and rarely by epithelioid angiosarcoma-like morphology. We report herein a 64-year-old man with a long-standing history of human immunodeficiency virus infection who developed a right adrenal tumor with a high-grade anaplastic angiosarcoma-like morphology. Immunohistochemistry for human herpes virus-8 was strongly positive in the tumor cells. To the best of our knowledge, this is the first report of an anaplastic Kaposi sarcoma in the adrenal gland.

    Full Text Available Congenital diaphragmatic hernia is a congenital defect of the diaphragm through which intestine and other viscera herniate into the chest. In extreme form of diaphragmatic maldevelopment, there might be a complete agenesis of diaphragm. A 45-day old male infant was presented with fever, cough and respiratory distress for a week. Chest radiograph showed right-sided congenital diaphragmatic hernia. The patient underwent surgical exploration and found to have an unusual and large defect of right hemidiaphragm. The diaphragm was absent on anterior and lateral aspects of the chest wall and only a small rim of diaphragm was present on posterior aspect. The defect was identified as agenesis of right hemidiaphragm and successfully managed by suturing the posterior rim of diaphragm to the intercostal muscles and ribs.

    Full Text Available Syphilis is an infectious disease caused by Treponema pallidum and has high rates of vertical transmission, which can reach 100% depending on the maternal disease and stage of pregnancy. The diagnosis of gestational syphilis is simple and its screening is required during the prenatal period. However, this disease still has a high prevalence, affecting two million pregnant women worldwide. The procedures performed in newborns with congenital syphilis represent costs that are three-fold higher than the ones spent with a baby without this infection. The treatment is generally carried out with penicillin and must be extended to sexual partners. Inadequate or lack of treatment of congenital syphilis can result in miscarriage, premature birth, acute complications and other fetal sequelae. KEYWORDS: Congenital syphilis. Treponema pallidum.

    Full Text Available Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (1 year is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.

    We report a case history of an 84-year-old elderly male patient that presented with a clinical picture suggestive of adrenal failure and bilateral adrenal nodules detected by abdominal computed tomography. A fine needle-guided biopsy was inconclusive for achieving a final diagnosis. The patient died due to septic shock and the autopsy disclosed histoplasmosis with extensive bilateral necrosis of the adrenal glands. Although the adrenal involvement in chronic disseminated histoplasmosis has been described, there have been few reports of the infection being associated with adrenal insufficiency.

    Full Text Available INTRODUCTION Neurofibromatosis type 1 is one of the most common genetically transmitted diseases with a high index of spontaneous mutations and extremely varied and unpredictable clinical manifestations. It is diagnosed by the existence of certain clinical criteria. The presence of numerous localised cutaneous neurofibromas or a plexiform neurofibroma is virtually pathognomonic of neurofibromatosis type 1. The incidence of pheochromocytoma in neurofibromatosis type 1 is 0.1-5.7%. CASE OUTLINE A 56-year old female patient was admitted for further evaluation of incidental adrenal tumour previously diagnosed on computerized tomography (CT. She had previously unrecognized neurofibromatosis type 1 and a clinical picture which could remind of pheochromocytoma. None of the catecholamine samples in 24 hr urine indicated functionally active pheochromocytoma. Chromogranin A was moderately increased. Decision for operation was made after performing the image techniques. Adrenal incidentaloma had features of pheochromocytoma on abdominal magnetic resonance imaging (MRI, with positive 131I-MIBG (iodine 131-labelled metaiodobenzylguanidine scintigraphy. After being treated with phenoxybenzamine and propranolol, she was operated on. The pathohistological finding showed the case of left adrenal pheochromocytoma. CONCLUSION Detailed diagnostic procedure for pheochromocytoma should be performed with patients having neurofibromatosis type 1 and adrenal incidentaloma. Pheochromocytomas are rare tumours with fatal outcome if not duly recognized and cured.

  3. Adrenal Insufficiency - Aetiology, Diagnosis and Treatment

    Full Text Available Adrenal insufficiency is caused by either primary adrenal failure or by hypothalamic-pituitary impairment of the corticotropic axis. Adrenal insufficiency, first codified in 1855 by Thomas Addison, remains relevant in 2014 because of its lethal nature. Though, it is a rare disease but is life threatening when overlooked. Main presenting symptoms such as fatigue, anorexia and weight loss are nonspecific, thus diagnosis is often delayed. The diagnostic work-up is well established but some pitfalls remain. The diagnosis is adequately established by the 250 μg ACTH (adrenocorticotropic hormone stimulation test in most cases. Glucocorticoids provide life saving treatment but long-term quality of life is impaired, perhaps because therapy is not given in a physiologic way. Dehydroepiandrosterone-replacement therapy has been introduced that could help to restore quality of life. It may be useful in pubertal girls, but not in adults. Monitoring of glucocorticoid-replacement is difficult due to lack of objective methods of assessment and is therefore largely based on clinical grounds. Thus, long-term management of patients with adrenal insufficiency remains a challenge, requiring an experienced specialist.

  5. Adrenal insufficiency in patients with decompensatedcirrhosis

    2015-01-01

    Adrenal reserve depletion and overstimulation of thehypothalamus-pituitary-adrenal (HPA) axis are causesfor adrenal insufficiency (AI) in critically ill individuals.Cirrhosis is a predisposing condition for AI in cirrhotics aswell. Both stable cirrhotics and liver transplant patients(early and later after transplantation) have been reportedto present AI. The mechanisms leading to reducedcortisol production in cirrhotics are the combination oflow cholesterol levels (the primary source of cortisol), theincreased cytokines production that overstimulate andexhaust HPA axis and the destruction of adrenal glandsdue to coagulopathy. AI has been recorded in 10%-82%cirrhotics depending on the test used to evaluate adrenalfunction and in 9%-83% stable cirrhotics. The similarityof those proportions support the assumption that AI isan endogenous characteristic of liver disease. However,the lack of a gold standard method for AI assessmentand the limitation of precise thresholds in cirrhoticsmake difficult the recording of the real prevalence of AI.This review aims to summarize the present data overAI in stable, critically ill cirrhotics and liver transplantrecipients. Moreover, it provides information about thecurrent knowledge in the used diagnostic tools and thepossible effectiveness of corticosteroids administration incritically ill cirrhotics with AI.

O cão morreu por peritonite séptica aguda, decorrente de ulceração e perfuração intestinal por corpo estranho linear. O neoplasma foi achado incidentalmente durante a necropsia. Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal.A case of bilateral adrenal myelolipoma in a 13-year-old female Poodle is reported. Acute septic peritonitis due to intestinal ulceration and perforation caused by a linear foreign body was the cause of death. The adrenal neoplasm was an incidental necropsy finding. The adrenal glands were grossly rounded, enlarged and friable, and had red-brownish parenchyma interwoven by slightly prominent white-yellowish foci. Histologically, the findings of differentiated adipocytes in large areas of the parenchyma, in association to hematopoietic cells and macrophages with hemosiderin were consistent with the diagnosis of adrenal myelolipoma.

    Full Text Available Delay of diagnosis of primary adrenal insufficiency (PAI leads to adrenal crisis which is potentially lethal complication. The objective of our work was an assessment whether the establishment of diagnosis of adrenocortical insufficiency in Poland is so much delayed as assessed in the past. We have analysed data from 60 patients with diagnosis of PAI established in our department during the past 12 years and who are still under our care. We found that the time to diagnosis of primary adrenal insufficiency in Poland exceeds 3 months in every patient and 6 months in patients admitted with symptoms of adrenal crisis. Forty-four percent of patients were diagnosed only just after the hospitalisation due to crisis, despite the evident signs and symptoms of PAI. Lack of appetite and loss of body weight occurred in all patients and for that reason a diagnosis of chronic gastric and duodenal ulcer disease was the most often incorrect diagnosis. After the proper diagnosis and treatment, in the course of 1–11 years of observation, there was only 6 imminent adrenal crises in 5 patients. Our results indicated that training of primary care physicians in the field of recognising and treatment of adrenal insufficiency is still essential.

    Acute infection of toxoplasmosis during pregnancy is detrimental to the developing fetus. In the United States, approximately 1 in 10,000 live births are affected by congenital toxoplasmosis. Although multifactorial in etiology, maternal infection is primarily attributed to the consumption of contaminated meat or water. Infection and transmission to the fetus may result in devastating neurologic impairment. Screening methods for all pregnant women should be implemented in routine prenatal care. This article will highlight the inherent dangers of congenital toxoplasmosis, while including general care of the fetus for prevention of transmission, medical management, and long-term outcomes.

    Congenital preduodenal portal vein, first reported by Knight in 1921, is an extremely rare congenital anomaly in which the portal vein passes anteriorly to the duodenum rather than posteriorly in its normal location. It is of surgical significance because it may cause difficulties in operations involving the gall bladder, biliary duct, or duodenum. Recently, we experienced 2 cases of preduodenal portal vein. One was found during surgical exploration for the diagnosis and correction of malrotation of the bowels and the other in a 3 day-old male newborn associated with dextrocardia, situs inversus, and duodenal obstruction by diaphragm. We report these 2 cases with a review of the literature.

    Full Text Available Los paragangliomas funcionales son tumores raros, se originan del tejido cromafín extraadrenal productor de catecolaminas, con frecuencia son malignos y tienen alta incidencia de enfermedad persistente o recurrente¹. Se les conoce como: glomus, quemodectomas, paragangliomas cromafines y glomerulocitomas. La localización es diversa y refleja la distribución paraganglionar en el cuerpo, desde la base del cráneo hasta el piso pélvico. Los paragangliomas se encuentran en donde hay ganglios del sistema autónomo, sin embargo, aproximadamente el 90% de estos tumores aparecen en las glándulas suprarrenales (y constituyen los feocromocitomas y el 10% restante tienen una ubicación extraadrenal, mas se ha dicho que su incidencia puede ser subestimada, variando del 18% al 22% en adultos, y en niños hasta un 30%. Los extra-adrenales se originan con mayor frecuencia en el abdomen (85%, otros en el tórax (12% y más raramente en la cabeza y el cuello (3% ². Los estudios de imágenes y la medición de la producción no fisiológica de catecolaminas pueden ayudar en el diagnóstico de esta entidad. La cirugía es el tratamiento de elección. Presentamos aquí el caso de una paciente de 32 años, primigesta con HTAIE que requirió cesárea, quien tuvo un postparto tórpido y pese a múltiples tratamientos antihipertensivos su patología fue de difícil manejo, con complicaciones oftálmicas. Tiempo después la paciente se estudia por hiperhidrosis, se solicitan exámenes de laboratorio e imágenes y se le documenta incidentalmente, una tumoración retroperitoneal izquierda, se le amplían los estudios, y se llega al diagnóstico correcto.

    Computed tomography (CT) of the adrenal glands was performed on seven patients who had histologically proved disseminated histoplasmosis. All seven patients showed some degree of adrenal gland abnormality. The range of CT findings included minimal enlargement with faint flecks of calcium, moderate enlargement with focal low attenuation nodules, and massive enlargement with large areas of necrosis or dense calcification. The changes in each patient were bilateral and symmetrical. Adrenal gland shape was usually preserved. Finding of percutaneous adrenal biopsy, which was performed under CT guidance, made the diagnosis in one patient. Five of seven patients had adrenal insufficiency. It is concluded that the diagnosis of disseminated histoplasmosis should be considered in any patient who has bilateral adrenal gland enlargement and who resides in an endemic area, especially if there is evidence of adrenal insufficiency.

    Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation. Mutiple radiological examinations detected bilateral adrenal atrophy. When the images were investigated in a more expanded scope, a 3.0×3.5×5.3 cm mass was detected in the anterior of left renal hilum and left renal vein. The mass was successfully resected with intraoperative endoscopy and pathological evaluation revealed an ectopic adrenal tumor. It is suggested that when the endocrinlogically confirmed adrenal neoplasm could not be well and definitely localized, the possibility of ectopic adrenal should be presumed and further radiography examinations should extend to the field where ectopic adrenal usually presents.

    2011-07-01

    A retrospective review of the literature was performed to determine the natural history, prevalence, prognosis and management of adrenal injury associated with blunt abdominal trauma in pediatric population. Blunt adrenal injury in children is uncommon, rarely isolated, and typically present as part of a multi organ trauma. Adrenal hemorrhage is being diagnosed more frequently since the emergence of computed tomography in modern emergency rooms. Obstetric birth trauma during vaginal delivery of a macrosomic fetus may result in neonatal adrenal hemorrhage. In children appear to be an incidental finding that resolves on follow-up imaging. Most of these injuries are self-limited and do not require intervention. The differential diagnosis of an adrenal neoplasm, especially in children with an isolated adrenal hemorrhage, must be considered. The presence of adrenal hemorrhage in the absence of a trauma history should alert to the possibility of pediatric inflicted injury.

    with an adrenal cystic lesion and biochemical testing concerning for pheochromocytoma. The pertinent diagnostic and imaging features of adrenal lymphangiomas are reviewed. Methods. We describe a 59-year-old patient who presented with hyperhidrosis and a 2.2 by 2.2 cm left adrenal nodule. Biochemical evaluation revealed elevated plasma-free normetanephrine, urine normetanephrine, urine vanillylmandelic acid, and urine norepinephrine levels. Elevated plasma norepinephrine levels were not suppressed appropriately with clonidine administration. Results. Given persistent concern for pheochromocytoma, the patient underwent adrenalectomy. The final pathology was consistent with adrenal lymphangioma. Conclusions. Lymphangiomas are benign vascular lesions that can very rarely occur in the adrenal gland. Imaging findings are generally consistent with a cyst but are nonspecific. Excluding malignancy in patients presenting with adrenal cysts can be difficult. Despite its benign nature, the diagnosis of adrenal lymphangioma may ultimately require pathology.

  2. Ectopic Thyroid Tissue in the Adrenal Gland: A Report of Two Cases with Pathogenetic Implications

    Background: Ectopic thyroid tissue is usually found anywhere along the embryonic descent pathway of the medial thyroid anlage from the tongue to the trachea (Wölfler area). However, ectopic thyroid tissue in the adrenal gland (ETTAG) is not easy to understand on the basis of thyroid embryology; because it is so rare, the possibility of metastasis should first be considered. Here, we describe two cases of ETTAG with pathogenetic implications and review the associated literature. Patient findings: Two cases of ETTAG presented as incidental cystic adrenal masses in adult females, one having a congenital hernia of Morgagni. The ETTAG was histologically indistinguishable from normal orthotopic thyroid tissue, and its follicular nature was confirmed by immunohistochemical positivity for thyroglobulin, thyroperoxidase, thyroid transcription factor-1 (TTF-1/Titf-1/Nkx2.1), cytokeratin AE1/AE3, cytokeratin 7, pendrin, human sodium iodide symporter, paired box gene 8, and forkhead box E1 (TTF-2), as well as positivity for the messenger RNA of the thyroglobulin gene by in situ hybridization analysis. No C cells (negativity for calcitonin, chromogranin, and synaptophysin) were present. Neither BRAF nor KRAS mutations were detected with real-time polymerase chain reaction analysis. Further work-up did not show evidence of thyroid malignancy. Summary: ETTAG is a rare finding, with only seven cases reported; women are much more frequently affected than men (8:1), and it usually presents in the fifth decade (mean age 54, range 38–67) as a cystic adrenal mass incidentally discovered on abdominal ultrasonography and/or in computed tomography images. ETTAG is composed of normal follicular cells without C cells. The expression of some transcription factors (TTF-1, paired box gene 8, and FOXE1) involved in development and/or migration of the medial thyroid anlage is preserved. Coexistence of a congenital hernia of Morgagni in one patient suggests an overdescent of medial thyroid

    Precerebellin (Cbln)-related peptides are known to modulate the secretory activity and growth of the adrenal gland. However, precise expression of the Cbln-related genes and Cbln1 peptide in the adrenal remains unclear. Therefore, we investigated, using RT-PCR, QPCR, Western blotting, immunohistochemistry and hormonal assays, their expression in the adrenals of adult rats and in the course of postnatal ontogenesis. Of the 4 known Cblns, Cbln(1-3) mRNAs were found in the adrenal gland of the adult male rats. Expression patterns of Cbln1 and 3 were similar to each other and different from that of Cbln2. Highest expression of the Cbln1 and 3 genes was observed in the zona glomerulosa (ZG), lower expression was noted in the fasciculata/reticularis and lowest expression was observed in the adrenal medulla. Expression of these genes was also present in freshly isolated rat adrenocortical cells. On the contrary, by means of classic RT-PCR, we demonstrated the presence of mRNAs of CBLN(1-4) in the human adrenal gland. In the rat, highest expression of the Cbln1 and 3 genes was found at postnatal day 2 and was somewhat lower at day 90. On the contrary, expression of the Cbln2 gene was low in adrenals of 2-day-old rats and notably higher at the remaining time points studied (up to day 360). Cerebellin (CER)-like immunoreactivity was observed in the membranes of the adrenal ZG cells, while in the medulla, immunoreactive substances were localized primarily in the cytoplasm of chromaffin cells. Cbln1-like immunoreactivity was present mainly in the cortex of the gland, and reaction products were noted both in the membranes and cytoplasm of adrenocortical cells. Semiquantitative evaluation of Cbln1 protein expression in compartments of the adrenal gland of the adult rat revealed a higher concentration of Cbln1 protein in the cortex than in the medulla of studied rats. We also found that both CER and desCER stimulated basal aldosterone secretion by freshly isolated ZG cells. Thus

  12. Congenitally corrected transposition

    2011-05-01

    Full Text Available Abstract Congenitally corrected transposition is a rare cardiac malformation characterized by the combination of discordant atrioventricular and ventriculo-arterial connections, usually accompanied by other cardiovascular malformations. Incidence has been reported to be around 1/33,000 live births, accounting for approximately 0.05% of congenital heart malformations. Associated malformations may include interventricular communications, obstructions of the outlet from the morphologically left ventricle, and anomalies of the tricuspid valve. The clinical picture and age of onset depend on the associated malformations, with bradycardia, a single loud second heart sound and a heart murmur being the most common manifestations. In the rare cases where there are no associated malformations, congenitally corrected transposition can lead to progressive atrioventricular valvar regurgitation and failure of the systemic ventricle. The diagnosis can also be made late in life when the patient presents with complete heart block or cardiac failure. The etiology of congenitally corrected transposition is currently unknown, and with an increase in incidence among families with previous cases of congenitally corrected transposition reported. Diagnosis can be made by fetal echocardiography, but is more commonly made postnatally with a combination of clinical signs and echocardiography. The anatomical delineation can be further assessed by magnetic resonance imaging and catheterization. The differential diagnosis is centred on the assessing if the patient is presenting with isolated malformations, or as part of a spectrum. Surgical management consists of repair of the associated malformations, or redirection of the systemic and pulmonary venous return associated with an arterial switch procedure, the so-called double switch approach. Prognosis is defined by the associated malformations, and on the timing and approach to palliative surgical care.

  13. What classicality? Decoherence and Bohr's classical concepts

    CERN Document Server

    Schlosshauer, Maximilian

    2010-01-01

    Niels Bohr famously insisted on the indispensability of what he termed "classical concepts." In the context of the decoherence program, on the other hand, it has become fashionable to talk about the "dynamical emergence of classicality" from the quantum formalism alone. Does this mean that decoherence challenges Bohr's dictum and signifies a break with the Copenhagen interpretation-for example, that classical concepts do not need to be assumed but can be derived? In this paper we'll try to shine some light down the murky waters where formalism and philosophy cohabitate. To begin, we'll clarify the notion of classicality in the decoherence description. We'll then discuss Bohr's and Heisenberg's take on the quantum-classical problem and reflect on different meanings of the terms "classicality" and "classical concepts" in the writings of Bohr and his followers. This analysis will allow us to put forward some tentative suggestions for how we may better understand the relation between decoherence-induced classical...

  14. Cushing syndrome associated with an adrenal tumour.

    Science.gov (United States)

    Vieira, Helena; Brain, Caroline

    2012-08-27

    Cushing syndrome (CS) in children is a rare disorder that is most frequently caused by an adrenal tumour or a pituitary corticotrophin-secreting adenoma. The management is challenging and requires an individualised approach and multidisciplinary care. We present the case of a 23-month-old female child with a history of excessive weight gain, growth failure, hirsutism, acne and behavioural difficulties. Investigations revealed elevated serum midnight cortisol and 24 h urinary free cortisol. Overnight dexamethasone suppression testing showed no suppression of cortisol levels. Abdominal imaging revealed a right-sided suprarenal mass. She underwent right adrenalectomy and the histology showed an adrenal cortical carcinoma. There was clinical improvement with catch-up growth and weight normalisation. Despite being rare in clinical practice, in a child with weight gain, hirsuitism and growth failure the diagnosis must be considered. The overall prognosis of CS in childhood is good, but challenges remain to ensure normal growth and body composition.

    In this work, we are presenting a simple mathematical model to simulate the control dynamics of synthesis, storage and secretion in an endocrine gland. In this, the hormone normally is synthetized from material selected and removed from the blood. In cell, material is processed and the final product, the hormone, can be stored until being released to the blood. The model associates the classical theory enzymatic kinetics to Lotka-Volterra equations. To test the proposed model, we take as an example the regulation of catecholamine synthesis-storage-release in the adrenal medulla.

    An 11-year-old spayed female pit bull terrier was presented with a 2-month history of polyuria, polydipsia, polyphagia, and panting. Serum chemistry, blood and urine analysis, and tests for hyperadrenocorticism suggested an adrenal tumor. Abdominal ultrasound identified a mass caudal to the right kidney. The mass was completely excised and histopathology was consistent with endocrine carcinoma. Three years later there was no evidence of recurrence or metastasis. PMID:25183891

    The coexistence of pheochromocytoma and renal artery stenosis had been reported occasionally from the possible mechanism of catecholoamine-induced vasospasm and extrinsic compression of renal artery in some reported cases. However, renal infarction caused by pheochromocytoma is an uncommon phenomenon. Herein, we report an interesting case of adrenal pheochromocytoma associated with renal artery thrombosis, which should be included in the differential diagnosis of pheochromocytoma patients who present with abdominal pain.

  18. Chronic Stress and Limbic-Hypothalamopituitary-Adrenal Axis (LHPA Response in Female Reproductive system

    Directory of Open Access Journals (Sweden)

    Farideh Zafari Zangeneh

    2009-12-01

    Full Text Available The hypothalamo-pituitary-adrenocortical (HPA axis is a critical adaptive system that maximizes survival potential in the face of physical or psychological challenge. The principal end products of the HPA axis, glucocorticoid hormones, act on multiple organ systems, including the brain, to maintain homeostatic balance. The brain is a target of stress, and the hippocampus is the first brain region, besides the hypothalamus, to be recognized as a target of glucocorticoids. These anatomical areas in brain are limbic system, and in particular the hippocampus, medial prefrontal cortex (mPFC and amigdal that have multiple control points in regulation of the hypothalamic–pituitary–adrenal (HPA axis. The studies show the prefrontal cortex (PFC plays an important role in the regulation of stress-induced hypothalamic–pituitary–adrenal (HPA activity and regulation of gonadal function in men and women is under the control of the HPA. This regulation is complex and sex steroids are important regulators of GnRH and gonadotropin release through classic feedback mechanisms in the hypothalamus and pituitary gland. Chronic stress can have a deleterious effect on the reproductive axis that, for females, is manifested in reduced pulsatile gonadotropin secretion and increased incidence of ovulatory abnormalities and infertility. The limbic–hypothalamic–pituitary–adrenal (LHPA axis suggests a functional role for gonadal steroids in the regulation of a female’s response to stress.

    This article provides the first assessment of theory of mind, that is, the ability to reason about mental states, in adult patients with congenital heart disease. Patients with congenital heart disease and matched healthy controls were administered classical theory of mind tasks and a semi-structured interview which provides a multidimensional evaluation of theory of mind (Theory of Mind Assessment Scale). The patients with congenital heart disease performed worse than the controls on the Theory of Mind Assessment Scale, whereas they did as well as the control group on the classical theory-of-mind tasks. These findings provide the first evidence that adults with congenital heart disease may display specific impairments in theory of mind.

    Full Text Available Objectives. To evaluate whether retroperitoneal approach for adrenalectomy is a safe and effective treatment for adrenal metastases (AM. Methods. From June 2004 to January 2014, nine consecutive patients with AM were treated with endoscopic retroperitoneal adrenalectomy (ERA. A retrospective study was conducted, and clinical data, tumor characteristics, and oncologic outcomes were acquired and analyzed. Results. Renal cancer was the primary site of malignancy in 44.4% of cases. The mean operative time was 132 ± 10.4 min. There were 5 synchronous and 4 metachronous AM. One patient required conversion to transperitoneal laparoscopic procedure. No mortality or perioperative complications were observed. The median overall survival was 11 months (range: 2–42 months. Survival rates of 50% and 25% were identified at 1 and 3 years, respectively. At the end of the study, 4 patients were alive with a mean observed follow-up of 20 months. No patients presented with local tumor relapse or port-site metastases. Conclusions. This study shows that ERA is a safe and effective procedure for resection of AM and advances the surgical treatment of adrenal disease. The use of the retroperitoneal approach for adrenal tumors less than 6 cm can provide very favorable surgical outcomes.

    Full Text Available Adrenal myelolipoma (AML is a rare benign tumor composed of mature adipose and hematopoietic tissue. Most of these patients are asymptomatic and the tumors are non-secreting. We present a case with a large functional adrenal myelolipoma, wherein the patient was hypertensive and biochemistry revealed increase in 24 hours urinary Vanillylmandelic Acid (VMA, a metabolite of catecholamine. The mass was removed surgically and diagnosed as adrenal myelolipoma on histopathological examination. Both his blood pressure and urinary VMA returned to normal following surgery, which suggested that the mass was functioning and was secreting catecholamine. To the best of our knowledge, a catecholamine secreting adrenal myelolipoma has been reported in the literature only once previously. The association of hypertension and adrenal myelolipoma may not be entirely coincidental, as it may be associated with secreting catecholamine, as seen in our case. We also review the literature on functioning adrenal myelolipoma.

    2011-01-01

    Full Text Available Congenital hemifacial hyperplasia (CHH is a rare congenital malformation characterized by marked unilateral overdevelopment of hard and soft tissues of the face. Asymmetry in CHH is usually evident at birth and accentuated with age, especially at puberty. The affected side grows at a rate proportional to the nonaffected side so that the disproportion is maintained thr oughout the life. Multisystem involvement has resulted in etiological heterogeneity including heredity, chromosomal abnormalities, atypical forms of twinning, altered intrauterine environment, and endocrine dysfunctions; however, no single theory explains the etiology adequately. Deformities of all tissues of face, including teeth and their related tissues in the jaw, are key findings for correct diagnosis of CHH. Here an attempt has been made to present a case of CHH with its archetypal features and to supplement existing clinical knowledge.

    Congenital diaphragmatic hernia, despite advances in therapy, remains a complex condition with significant morbidity and mortality. The etiology of the disorder is still incompletely understood, though the pulmonary hypoplasia and pulmonary hypertension that develop secondarily must be overcome to improve survival. Prenatal US and fetal MRI have helped in the development of a greater understanding of this disease. Also with these modalities, measurement techniques have been developed in an attempt to provide prognosticators for the development of pulmonary hypoplasia and pulmonary hypertension. There is a broad range of approaches for performing these measurements, and variability among imaging centers is noted. Despite inconsistent approaches, these techniques have become the foundation for counseling and prenatal and postnatal therapy. It is hoped that with further research with prenatal US and fetal MRI and the development of innovative medical and surgical therapies that the morbidity and mortality of children with congenital diaphragmatic hernias can be significantly reduced.

    Full Text Available Face The Examiner:QUESTIONS1. What are the diagnostic features of congenital pouch colon (CPC?Ans: A male patient with CPC often have a wide colovesical fistula and present with anorectal malformation and meconuria; on plain abdominal film, a single large bowel loop occupying more than 50% of the abdominal cavity is also a diagnostic sign. Girls (persistent cloaca/vestibular fistula/anteriorly placed anus etc. often present late with intractable constipation or multiple episodes of enterocolitis and persistent abdominal distension with common cloaca or anterior ectopic anus/ rectovestibular fistula. The congenital pouch colon can be identified as replacement of a part or entire colon in the configuration of pouch that lacks taenia coli, haustrations, appendices epiploicae, abnormal blood supply and a wide fistula with genitourinary system in a patient of anorectal malformation.

    2014-09-01

    Lipodystrophies are rare acquired and genetic disorders characterized by the selective loss of adipose tissue. One key metabolic feature of patients with congenital inherited lipodystrophy is hypertriglyceridemia. The precise mechanisms by which the lack of adipose tissue causes dyslipidemia remain largely unknown. In recent years, new insights have arisen from data obtained in vitro in adipocytes, yeast, drosophila, and very recently in several genetically modified mouse models of generalized lipodystrophy. A common metabolic pathway involving accelerated lipolysis and defective energy storage seems to contribute to the dyslipidemia associated with congenital generalized lipodystrophy syndromes, although the pathophysiological changes may vary with the nature of the mutation involved. Therapeutic management of dyslipidemia in patients with lipodystrophy is primarily based on specific approaches using recombinant leptin therapy. Preclinical studies suggest a potential efficacy of thiazolidinediones that remains to be assessed in dedicated clinical trials.

    Full Text Available Background. Congenital intestinal lymphangiectasia is a disease which leads to protein losing enteropathy. Tortous, dilated lymphatic vessels in the intestinal wall and mesenterium are typical features of the disease. Clinical manifestations include malabsorption, diarrhea, steatorrhea, edema and effusions. Specific diet and medication are required for disease control. Case report. A 19-year old male patient was hospitalized due to diarrhea, abdominal swelling, weariness and fatigue. Physical examination revealed growth impairment, ascites, and lymphedema of the right hand and forearm. Laboratory assessment indicated iron deficiency anaemia, lymphopenia, malabsorption, inflammatory syndrome, and urinary infection. Enteroscopy and video capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy. The patient was put on high-protein diet containing medium-chain fatty acids, somatotropin and suportive therapy. Conclusion. Congenital intestinal lymphangiectasia is a rare disease, usually diagnosed in childhood. Early recognition of the disease and adequate treatment can prevent development of various complications.

  7. Prednisolone is associated with a worse lipid profile than hydrocortisone in patients with adrenal insufficiency

    Directory of Open Access Journals (Sweden)

    Marcus Quinkler

    2016-12-01

    Full Text Available Objective: Prednisolone is used as glucocorticoid replacement therapy for adrenal insufficiency (AI. Recent data indicate that its use in AI is associated with low bone mineral density. Data on risk factors for cardiovascular disease in patients with AI treated with prednisolone are scarce, despite this condition being the predominant cause of excess mortality. We aimed to address this question using real-world data from the European Adrenal Insufficiency Registry (EU-AIR. Design/methods: EU-AIR, comprising of 19 centres across Germany, the Netherlands, Sweden and the UK, commenced enrolling patients with AI in August 2012. Patients receiving prednisolone (3–6 mg/day, n = 50 or hydrocortisone (15–30 mg/day, n = 909 were identified and grouped at a ratio of 1:3 (prednisolone:hydrocortisone by matching for gender, age, duration and type of disease. Data from baseline and follow-up visits were analysed. Data from patients with congenital adrenal hyperplasia were excluded. Results: Significantly higher mean ± s.d. total (6.3 ± 1.6 vs 5.4 ± 1.1 mmol/L; P = 0.003 and low-density lipoprotein (LDL cholesterol levels (3.9 ± 1.4 vs 3.2 ± 1.0 mmol/L; P = 0.013 were identified in 47 patients on prednisolone vs 141 receiving hydrocortisone at baseline and at follow-up (P = 0.005 and P = 0.006, respectively. HbA1c, high-density lipoprotein and triglyceride levels, body mass index, systolic and diastolic blood pressure and waist circumference were not significantly different. Conclusions: This is the first matched analysis of its kind. Significantly higher LDL levels in patients receiving prednisolone relative to hydrocortisone could predict a higher relative risk of cardiovascular disease in the former group.

    The Endocrine Society Clinical Practice Guidelines on congenital adrenal hyperplasia (CAH) recommend against using hydrocortisone suspension based on a study that examined a commercial suspension. Our objective was to examine the absorption of an extemporaneously prepared hydrocortisone suspension and compare it to tablets. Secondary objectives were to evaluate the 17-hydroxyprogesterone and androstenedione adrenal steroid responses. Using a parallel design, 34 children diagnosed with CAH received either suspension (n = 9; median age 1.8 years) or tablets (n = 25; median age 7.5 years). Patients were given their usual morning hydrocortisone formulation and dose; 12 serial blood samples were obtained and the area under the curve (AUC) was calculated. The mg/m(2) dose-normalized cortisol AUCs were no different in the suspension and tablet groups (P = ·06), nor was there a significant difference in the C(max) or T(max) (P = .08 and P = .41, respectively). Although there were no differences in the 17-hydroxyprogesterone change-from-baseline AUCs, baseline concentrations, or the nadir concentrations when comparing suspension and tablet formulations, the androstenedione values were significantly lower as expected in the younger aged suspension group. Our results offer compelling evidence that an extemporaneously prepared hydrocortisone suspension provides comparable cortisol exposures to commercially available tablet formulations in children and can be used to safely and effectively treat CAH.

    Full Text Available Congenital spinal vertebral anomalies can present as scoliosis or kyphosis or both. The worldwide prevalence of the vertebral anomalies is 0.5-1 per 1000 live births. Vertebral anomalies can range from hemi vertebrae (HV which may be single or multiple, vertebral bar with or without HV, block vertebrae, wedge shaped or butterfly vertebrae. Seventy per cent of congenital vertebral anomalies result in progressive deformities. The risk factors for progression include: type of defect, site of defect (junctional regions and patient′s age at the time of diagnosis. The key to success in managing these spinal deformities is early diagnosis and anticipation of progression. One must intervene surgically to halt the progression of deformity and prevent further complications associated with progressive deformity. Planning for surgery includes a preoperative MRI scan to rule out spinal anomalies such as diastematomyelia. The goals of surgical treatment for congenital spinal deformity are to achieve a straight growing spine, a normal standing sagittal profile, and a short fusion segment. The options of surgery include in situ fusion, convex hemi epiphysiodesis and hemi vertebra excision. These basic surgical procedures can be combined with curve correction, instrumentation and short segment fusion. Most surgeons prefer posterior (only surgery for uncomplicated HV excision and short segment fusion. These surgical procedures can be performed through posterior, anterior or combined approaches. The advocates of combined approaches suggest greater deformity correction possibilities with reduced incidence of pseudoarthrosis and minimize crankshaft phenomenon. We recommend posterior surgery for curves involving only an element of kyphosis or modest deformity, whereas combined anterior and posterior approach is indicated for large or lordotic deformities. In the last decade, the use of growing rods and vertebral expandable prosthetic titanium rib has improved the

    Adrenal crisis occurs when there is decreased secretions of steroid hormones (mainly cortisol) from the adrenal glands due to varied reasons. It may arise due to a primary adrenal condition or due to decreased hormonal signals from the pituitary secondary to a hypofunctioning pituitary. Hypopituitarism may result due to direct causes like trauma, tumour, infection or it may be due to some vascular insult as seen in Sheehan syndrome. We report an unusual presentation of Sheehan syndrome in the form of life-threatening adrenal crisis precipitated by the usage of rifampicin. PMID:24339502

    Congenital agenesis of the seminal vesicle (CASV) is frequently associated with congenital absence of the vas deferens (CAVD) or ipsilateral congenital vasoureteral communication. We reported two cases of a rare condition that the vas deferens open ectopically into Mullerian duct cyst associated with agenesis of the ipsilateral seminal vesicle. The diagnosis was confirmed by vasography. Transurethral unroofing of the Mullerian duct cyst was performed in both patients with favourable results, however, assisted reproductive technology (ART) was still necessary for them to father children.

    Full Text Available Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson′s teeth.

    clinical concern. Although in most cases they are benign and hormonally nonfunctioning, it is important to appropriately identify those few cases of malignant or hyperfunctioning lesions of surgical resolution. Although several proposals for an optimal diagnostic strategy have been designed, controversy over a series of questions still persists. In the present retrospective study we analyzed 34 patients with adrenal incidentaloma. Of these, 32% of the patients displayed hyperfunctioning pathologies that included subclinical Cushing's syndrome in four patients, probable primary hyperaldosteronism in two, late onset congenital adrenal hyperplasia in one, adrenocortical carcinoma in one and pheochromocytoma in three. CT and/or MRI permitted the identification of adenomas and were crucial to decide on surgery in two patients with nonfunctioning pheochromocytomas and in a patient carrying a primitive adrenocortical carcinoma, a diagnosis also suggested by a mixed pattern of hypersecretion of androgens and cortisol. In a diabetic and hypertensive patient with subclinical Cushing's syndrome both comorbidities were solved by surgery. Nonfunctioning tumors were mainly adenomas (87% with individual cases of histoplasmosis, pseudocyst, idiopathic adrenal hyperplasia and mielolipoma. Six of the eight operated patients presented malignant and/or hyperfunctioning tumors. The pathology associated with incidentalomas represents a broad spectrum of risk for patients and reaffirms the necessity for a meticulous clinical, biochemical, and imaging evaluation in order to make appropriate decisions.

    Classical lissencephaly may be associated with cerebellar hypoplasia and when significant cerebellar abnormalities occur, defects in proteins encoded by TUBA1A, RELN, and very-low-density lipoprotein receptor (VLDLR) genes have been reported. We present a neonate with a severe neurologic phenotype associated with hypotonia, oropharyngeal incoordination that required a gastric tube for feeding, intractable epilepsy, and congenital cataracts. Her brain magnetic resonance imaging (MRI) showed classical lissencephaly, ventriculomegaly, absent corpus callosum, globular and vertical hippocampi, and severe cerebellar and brainstem hypoplasia. She died at 6 weeks of age. No specific molecular diagnosis was made. This likely represents a previously undescribed genetic lissencephaly syndrome.

    Background Congenital hypothyroidism of thyroidal origin (CHT) is a common disorder in pediatric endocrinology practices, which can be difficult to manage. Elevated thyrotropin (TSH) concentrations are in the great majority of cases explained by poor compliance to levothyroxine therapy. Methods Case description. Results We present a boy with CHT, with 2 heterozygous mutations in the TSH receptor gene, who showed persistently elevated TSH concentrations and psychomotor retardation, initially misinterpreted as malcompliance. At the age of 4 years, he was diagnosed with adrenal insufficiency, wherefore a broad diagnostic search was initiated. After the start of glucocorticoid replacement therapy, his TSH normalized and the levothyroxine could be lowered. At the age of 6 years, his TSH increased again, this time caused by malabsorption of levothyroxine due to esophageal achalasia. In retrospect, alacrima was also present and the diagnosis of Allgrove syndrome was genetically confirmed. The CHT was considered a separate disease entity. Conclusions In case of persistently elevated TSH levels in children with CHT, causes other than noncompliance must be considered. Second, in establishing the cause of adrenal insufficiency, specific symptoms, such as alacrima, are easily overlooked. Third, Allgrove syndrome is a rare disorder, in which diagnostic delay can lead to potentially life-threatening complications. PMID:27255745

    The emerging field of entanglement or nonseparability in classical optics is reviewed, and its similarities with and differences from quantum entanglement clearly pointed out through a recapitulation of Hilbert spaces in general, the special restrictions on Hilbert spaces imposed in quantum mechanics and the role of Hilbert spaces in classical polarization optics. The production of Bell-like states in classical polarization optics is discussed, and new theorems are proved to discriminate between separable and nonseparable states in classical wave optics where no discreteness is involved. The influence of the Pancharatnam phase on a classical Bell-like state is deived. Finally, to what extent classical polarization optics can be used to simulate quantum information processing tasks is also discussed. This should be of great practical importance because coherence and entanglement are robust in classical optics but not in quantum systems.

    Full Text Available Abstract Objective: To assess the feasibility and reliability of apparent diffusion coefficient (ADC measurements of normal adrenal glands. Materials and methods: This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12, aged from 2 months to 12.5 years (4 males; 8 females; and postpubertal (PostP, n = 20, aged from 11.9 to 61 years (5 males; 15 females. Diffusion-weighted magnetic resonance imaging (DW-MRI sequences were acquired at a 1.5 T scanner using b values of 0, 20, 500, and 1000 s/mm2. Two radiologists evaluated the images. ADC values were measured pixel-by-pixel on DW-MRI scans, and automatic co-registration with the ADC map was obtained. Results: Mean ADC values for the right adrenal glands were 1.44 × 10-3 mm2/s for the PreP group and 1.23 × 10-3 mm2/s for the PostP group, whereas they were 1.58 × 10-3 mm2/s and 1.32 × 10-3 mm2/s, respectively, for the left glands. ADC values were higher in the PreP group than in the PostP group (p < 0.05. Agreement between readers was almost perfect (intraclass correlation coefficient, 0.84-0.94; p < 0.05. Conclusion: Our results demonstrate the feasibility and reliability of performing DW-MRI measurements of normal adrenal glands. They could also support the feasibility of ADC measurements of small structures.

    Introdução: A hiperplasia congénita da suprarrenal por deficiência de 21-hidroxílase constitui uma das doenças hereditárias mais comuns. Resulta de diferentes mutações no gene CYP21A2 e, na maioria dos casos, a gravidade da doença correlaciona-se com a variação alélica do CYP21A2. O objetivo deste estudo foi descrever o espectro mutacional do CYP21A2 e avaliar a correlação genótipo-fenótipo numa coorte de doentes portugueses com deficiência de 21-hidroxílase. Material e Métodos: Estudo retrospetivo de 22 doentes com diagnóstico clínico de deficiência de 21-hidroxílase. Foi feita análise molecular do CYP21A2 e estabelecida a correlação genótipo-fenótipo. Resultados: Foi realizada genotipagem em 22 doentes não relacionados: 5 com a forma clássica perdedora de sal (idade média ao diagnóstico de 10,2 dias; mínimo 1, máximo 20 dias), 7 com a forma clássica virilizante simples (idade média ao diagnóstico de 3,5 anos; mínimo 0 dias, máximo 7 anos) e 10 com a forma não clássica (idade média ao diagnóstico de 5,7 anos; mínimo 4 anos, máximo 8 anos). Os defeitos genéticos mais frequentes nas formas clássicas foram o I2 splice (24%) e I172N (24%), seguindo-se o Q318X (16%) e deleções de genes (16%) e, na forma não clássica, o V281L (80%). Verificou-se uma concordância genótipo-fenótipo global de 81,8%. O genótipo permitiu prever adequadamente o fenótipo em 83,3%, 100% e 90% dos doentes com mutações compatíveis com a forma clássica perdedora de sal, clássica virilizante simples e não clássica, respectivamente. Discussão: A frequência de defeitos genéticos observados nos nossos doentes é comparável a estudos semelhantes. Observou-se, na maioria dos casos, uma boa correlação genótipo-fenótipo. Conclusões: A análise molecular do CYP21A2 fornece informação importante relativamente à gravidade da doença e no aconselhamento genético e pré-natal.

    Larissa G. Gomes

    2013-01-01

    Full Text Available OBJECTIVE: The protocols for glucocorticoid replacement in children with salt wasting 21-hydroxylase deficiency are well established; however, the current recommendation for mineralocorticoid replacement is general and suggests individualized dose adjustments. This study aims to retrospectively review the 9-∝-fludrocortisone dose regimen in salt wasting 21-hydroxylase deficient children who have been adequately treated during infancy. METHODS: Twenty-three salt wasting 21-hydroxylase deficient patients with good anthropometric and hormonal control were followed in our center since diagnosis. The assessments of cortisone acetate and 9-∝-fludrocortisone doses, anthropometric parameters, and biochemical and hormonal levels were rigorously evaluated in pre-determined intervals from diagnosis to two years of age. RESULTS: The 9-∝-fludrocortisone doses decreased over time during the first and second years of life; the median fludrocortisone doses were 200 µg at 0-6 months, 150 µg at 7-18 months and 125 µg at 19-24 months. The cortisone acetate dose per square meter was stable during follow-up (median = 16.8 mg/m²/day. The serum sodium, potassium and plasma rennin activity levels during treatment were normal, except in the first month of life, when periodic 9-∝-fludrocortisone dose adjustments were made. CONCLUSIONS: The mineralocorticoid needs of salt wasting 21-hydroxylase deficient patients are greater during early infancy and progressively decrease during the first two years of life, which confirms that a partial aldosterone resistance exists during this time. Our study proposes a safety regiment for mineralocorticoid replacement during this critical developmental period.

    We report a case of gender dysphoria (GD) in a 62-year-old genetic female patient, raising the pros and cons of performing corrective surgery later in life. This 46,XX DSD patient was registered and reared as a girl; CAH was diagnosed late in childhood. Poor adherence to treatment and lack of proper psychological management contributed to evident GD. Living for years as a male, the patient applied for a legitimate male identification document in his late 50s; thereafter, he requested a sex-reassignment surgery "to disguise his female body upon his death." We informed the patient and family about surgery hazards, while analytical therapy allowed the group to evaluate the actual wish for surgery. When the wish was brought up, the role of death urged the group to rethink the course of treatment. During the process, it became clear that the patient's desire for surgery, more than a wish for changing the genitalia, expressed an impulse related to issues of endorsement and acceptance of his male identity. This report raises interesting questions about sexuality in a social context and prompts the idea that sexuality is broader than sex itself, raising new questions on the psychological risks faced when considering a body change after years of living with a disorder of sex development.

    Full Text Available Congenital malformation (CM will begin to emerge as one of the major childhood health problems .Treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. The aim of this study was to determine frequency of CM in Yazd central city of the Islamic Republic of Iran to find out if there has been any difference in the rate and types of CM in this area. This descriptive-observational study carried on 4800 births delivered at all maternity hospitals in Yazd from October 2003 to June 2004. Prevalence of CM was 2.83% (2.86 % in male and 2.68 % in female out of the 136 cases 69(51.88% were males and 64 (48.12% were females and 3 with ambiguous genitalia. Positive family history of CM in sibling was in only 6 cases (4.41%.Overall, musculoskeletal (0.83%, central nerv-ous system (0.47% and genital system (0.37% were accounted as the most common. Frequency of CM was more seen in still birth (12.5% as in comparison to live birth (2.71%. There was not statistical difference be-tween prevalence of CM and neonatal's gender, gestational age, birth order and mother's age, drug ingestion, illness and parental consanguinity. In this study the overall prevalence of congenital malformation among the newborn was higher than those previous reported in Iran and determining the causes of this difference needs more extensive studies.

    Full Text Available Systemic lymphangiomatosis is a rare disease characterized by the exageration of lymphatic channel proliferation, occurring in children and young adults. We describe an extremely rare case of congenital systemic lymphangiomatosis in a newborn who had ascitis and respiratory failure develop immediately after delivery. Death occurred during the first hour of life. Autopsy findings showed numerous cysts in soft tissues of the cervical area, mediastinum and diaphragm, and several other organs including the liver, spleen, thyroid and kidneys. The severe and diffuse involvement with cysts in both lungs by lymphangiomatosis was associated with poor prognosis and death in our case.

    Congenital granular cell epulis is a rarely reported lesion of unknown histogenesis with a strong predilection for the maxillary alveolar ridge of newborn girls. Microscopically, it demonstrates nests of polygonal cells with granular cytoplasm, a prominent capillary network, and attenuated overlying squamous epithelium. The lesion lacks immunoreactivity for S-100, laminin, chromogranin, and most other markers except neuron-specific enolase and vimentin. Through careful observation of its unique clinical, histopathologic, and immunohistochemical features, this lesion can be distinguished from the more common adult granular cell tumor as well as other differential diagnoses.

    Full Text Available The management of congenital cataract is very different to the treatment of a routine age-related cataract. In adults, surgery may be delayed for years without affecting the visual outcome. In infants, if the cataract is not removed during the first year of life, the vision will never be fully regained after surgery. In adults, if the aphakia is not corrected immediately, it can be corrected later. In young children, if the aphakia is not corrected, the vision will never develop normally.

    1. This complex of symptoms appears to be congenital, familial, and hereditary. It is apparently transmitted by a dominant gene, probably on chromosome 5. 2. Hypertonicity with rigidity of all voluntary muscles usually presents at birth. 3. Feeding problems are due to dysphagia or laryngospasm associated with aspiration and dyspnea. 4. Respiratory problems are characterized by apneic episodes due to muscle spasm. 5. Prolonged episodes of muscular rigidity secondary to sudden stimuli result in frequent falls, characteristically en bloc, like a statue. 6. Continuous electromyographic activity even at rest (with absence of fasciculations) improves after intravenous diazepam.

    Full Text Available Abstract Congenital Diaphragmatic Hernia (CDH is defined by the presence of an orifice in the diaphragm, more often left and posterolateral that permits the herniation of abdominal contents into the thorax. The lungs are hypoplastic and have abnormal vessels that cause respiratory insufficiency and persistent pulmonary hypertension with high mortality. About one third of cases have cardiovascular malformations and lesser proportions have skeletal, neural, genitourinary, gastrointestinal or other defects. CDH can be a component of Pallister-Killian, Fryns, Ghersoni-Baruch, WAGR, Denys-Drash, Brachman-De Lange, Donnai-Barrow or Wolf-Hirschhorn syndromes. Some chromosomal anomalies involve CDH as well.

    Purpose: To evaluate the incidence and cause of hypertension prospectively during adrenal radiofrequency ablation (RFA). Methods: For this study, approved by our institutional review board, written informed consent was obtained from all patients. Patients who received RFA for adrenal tumors (adrenal ablation) and other abdominal tumors (nonadrenal ablation) were included in this prospective study. Blood pressure was monitored during RFA. Serum adrenal hormone levels including epinephrine, norepinephrine, dopamine, and cortisol levels were measured before and during RFA. The respective incidences of procedural hypertension (systolic blood pressure >200 mmHg) of the two patient groups were compared. Factors correlating with procedural systolic blood pressure were evaluated by regression analysis.ResultsNine patients underwent adrenal RFA and another 9 patients liver (n = 5) and renal (n = 4) RFA. Asymptomatic procedural hypertension that returned to the baseline by injecting calcium blocker was found in 7 (38.9%) of 18 patients. The incidence of procedural hypertension was significantly higher in the adrenal ablation group (66.7%, 6/9) than in the nonadrenal ablation group (11.1%, 1/9, P < 0.0498). Procedural systolic blood pressure was significantly correlated with serum epinephrine (R{sup 2} = 0.68, P < 0.0001) and norepinephrine (R{sup 2} = 0.72, P < 0.0001) levels during RFA. The other adrenal hormones did not show correlation with procedural systolic blood pressure. Conclusion: Hypertension occurs frequently during adrenal RFA because of the release of catecholamine.

    Objective To explore expression of endogenous ouabain(EO) in multiple adrenal tumors.Methods Thirty-one cases of adrenal tumors and 6 cases of healthy adrenal tissues were selected. The expression of EO in the adrenal tiss ue was detected with immunohistochemical streptavidin peroxadase conjugated(SP) method.Results Most of EO positive products were localized in cy toplasm of the zona reticularis of human adrenal cortex, and positive products s howed to be fine granular. There was no positive signal in the medulla. EO showe d on diffused positive in patients with pheochromocytoma accompanied high blood pressure[SBP:(165.22±7.61) mmHg, DBP:(105.52±4.26) mmHg], but there were neg ative in ones with normative blood pressure[SBP:(118.52±4.58) mmHg, DBP:(83±3.60) m mHg]. The expression of EO was positive in all adrenocortical hyperplasic, aden oma an d carcinoma, no matter its high or normative blood pressure. The degree of expre ssion of EO in adrenal tissues was related to the level of BP.Conclusion Expression of endogenous ouabain(EO) in health y adrenal tissue and adrenal tumors was a valuable morphological and pathophysio logical clue for the research on ouabain.

    2011-03-01

    In the last 30 years the development and widespread use of modern imaging techniques has caused a 20-time increase in the diagnosis of adrenal incidentaloma (AI). Among AIs myelolipoma (ML) is reported with a frequency up to 10%. In the literature 8 patients with adrenal masses in thalassaemia or chronic haemolytic anaemia have been reported: five cases were shown to have extramedullary haematopoiesis (EH) and 3 ML. We describe here a case of an adult male affected by beta thalassaemia intermedia and large bilateral lipomatous adrenal masses. The patient was referred to our ward at the age of 55 and underwent hormonal testing, MRI, and SPECT/CT scans. Adrenal masses were hormonally inactive, and fat-containing on MRI and CT scans. SPECT/CT examination with 99mTccolloid demonstrated the presence of marrow tissue. ML and EH are the only two tumours with marrow tissue among lipomatous adrenal masses. In our patient a brown nodular mass was resected and histologically classified as ML. In benign adrenal masses, radiological follow-up is indicated; in case of large bilateral masses adrenal function tests are suggested periodically in order to detect possible adrenal hypofunction.

    Full Text Available We report a case of synchronous bilateral adrenal metastasis of renal cell carcinoma. The contralateral metastatic adrenal mass was treated by the laparoscopic transperitoneal approach. The renal mass and its huge ipsilateral metastatic adrenal gland were removed en bloc with open procedure. A 54-year-old man presented to our clinic with left-sid renal cell carcinoma synchronously bilateral adrenal metastases. The primary tumor was localized in the upper-mid pole of the kidney. The diagnosis was established preoperatively by computed tomography. The size of the contralateral adrenal mass was 65 x 45 mm, but the ipsilateral metastatic adrenal mass was huge (140 x 65 mm. After all analysis and other scannings for any metastasis, a contralateral lapararoscopic transperitoneal adrenalectomy and a left open nephroadrenalectomy were performed simultaneously. Synchronous bilateral adrenal metastases from primary renal cell carcinoma without another metastasis is very rare. The optimal surgical procedure should be selected according to the metastatic adrenal masses size and the patient%u2019s status.

The precise diagnosis requires detailed clinical examination and electrophysiological findings. This case report presents two male patients with congenital nystagmus examined longitudinally from the age of six months until 17-18 years of age. Clinical and electrophysiological protocols were detailed. The first results showed electronegative electroretinography in the two cases and examination combined with electroretinographic findings helped us to make the diagnosis of Congenital Night Stationary Blindness (CSNB. This diagnosis was confirmed by genetic studies.

    Laparoscopic adrenalectomy is considered to be the standard of care for the surgical excision of adrenal masses. The transperitoneal laparoscopic and retroperitoneoscopic approaches are described. Both are safe and as effective as open adrenalectomy, with the added benefit of the minimally invasive approach. It can be utilized for patients requiring surgery for a phaeochromocytoma, adrenal adenoma, adrenal adenocarcinoma, Cushing's syndrome, neuroblastoma, and an incidentaloma. Relative contraindications include previous surgery of the liver or kidney, large tumours (>8-10 cm in diameter) or coagulation disorders. Although the transperitoneal route is used more widely, the retroperitoneal approach provides direct access to the adrenal gland and easy visualization of the adrenal vein. It avoids also colonic mobilization, minimizes the risk of injury to hollow viscera, and the potential risk of adhesion formation. However, the reversed orientation of the kidney and hilum, combined with a significantly smaller working space, may make this approach difficult to master.

Adrenal vein sampling (AVS is a procedure entailing the measurement of aldosterone from both adrenal veins, to diagnose an adrenal source of excess aldosterone secretion. Because unilateral adrenal etiologies of primary aldosteronism may be surgically resected, identifying these sources by venous sampling is critical.

    Synchronous laparoscopic resections of coexisting abdominal diseases are shown to be feasible without additional postoperative morbidity. We report our experience with synchronous laparoscopic resection of colorectal carcinoma and renal/adrenal neoplasms with an emphasis on surgical and oncologic outcomes. Five patients diagnosed to have synchronous colorectal carcinoma and renal/adrenal neoplasms (renal cell carcinoma in 2 patients, adrenal cortical adenoma in 2 patients, and adrenal metastasis in 1 patient) underwent synchronous laparoscopic resection. The median operative time was 420 minutes and the median operative blood loss was 1000 mL. Three patients developed minor complications, including wound infection in 2 patients and retention of urine in 1 patient. There was no operative mortality. The median duration of hospital stay was 11 days. At a median follow-up of 17.6 months, no patient developed recurrence of disease. Synchronous laparoscopic resection of colorectal and renal/adrenal neoplasms is technically feasible and safe.

    2012-10-20

    Congenital deafness is defined as the hearing loss which is present at birth and, consequently, before speech development. It is the most prevalent sensor neural disorder in developed countries, and its incidence is estimated between 1-3 children per 1,000 newborns, of which more than 50% are attributable to genetics causes. Deafness can be classified as syndromic or non-syndromic. In the first case, it is associated with outer ear malformations and/or systemic findings. More than 400 syndromes accompanied of deafness have been described, which represent about 30% of cases of congenital hearing loss. The remaining percentage corresponds to non-syndromic cases: 75-85% are autosomal recessive, 15-24% are autosomal dominant, and 1-2% are X-linked. The evaluation of a child with deafness requires a multidisciplinary collaboration among specialists, who must coordinate themselves and give information to the affected family. The aims of establishing a diagnosis are to predict other manifestations that may suggest some syndrome and to anticipate their management, as well as to perform genetic counseling to parents and affected individuals.

    A congenital extrahepatic portosystemic shunt (CEPS) is uncommon. A type 1 CEPS exists where there is absence of intrahepatic portal venous supply and a type 2 CEPS where this supply is preserved. The diagnosis of congenital portosystemic shunt is important because it may cause hepatic encephalopathy. To describe the clinical and imaging features of three children with CEPS and to review the cases in the published literature. The diagnostic imaging and medical records for three children with CEPS were retrieved and evaluated. An extensive literature search was performed. Including our cases, there are 61 reported cases of CEPS, 39 type 1 and 22 type 2. Type 1 occurs predominantly in females, while type 2 shows no significant sexual preponderance. The age at diagnosis ranges from 31 weeks of intrauterine life to 76 years. Both types of CEPS have a number of associations, the most common being nodular lesions of the liver (n=25), cardiac anomalies (n=19), portosystemic encephalopathy (n=10), polysplenia (n=9), biliary atresia (n=7), skeletal anomalies (n=5), and renal tract anomalies (n=4). MRI is recommended as an important means of diagnosing and classifying cases of CEPS and examining the associated cardiovascular and hepatic abnormalities. Screening for CEPS in patients born with polysplenia is suggested. (orig.)

    Peritoneal encapsulation(PE) is a rare congenital malformation, characterized by a thin accessory peritoneal membrane which covers all or part of the small bowel, forming an accessory peritoneal sac. Most cases areasymptomatic and diagnosed incidentally during surgery and/or autopsy. Clinical presentation with intestinal obstruction is extremely rare and we report a case. A 25-year-old male, referred to emergency department with diffuse abdominal pain, crampy, with 8 h evolution, associated with nausea, vomiting and constipation in the last 48 h. The abdominal examination revealed an asymmetric and fixed distension, with hard consistency on palpation of lower abdominal quadrants. The abdominal radiography reveals a small bowel distension and fluid levels. Submitted to laparoscopic surgery that recourse to conversion because there is a total peritoneal encapsulation of the small bowel. After opening the peritoneal sac, we find a rotation of mesentery, at its root, conditioning twisting of small bowel and consequently occlusion.

    People are at higher risk of cancer as they get older or have a strong family history of cancer. The potential influence of environmental and behavioral factors remains poorly understood. Earlier population and case control studies reported that upper quartile of circulating IGF-I is associated with a higher risk of developing cancer suggesting possible involvement of the growth hormone (GH)/IGF system in initiation or progression of cancer. Since GH therapy increases IGF-1 levels, there have been concerns that GH therapy in hypopituitarism might increase the risk of cancer. We report a 42-year-old female patient who presented with subacute onset of symptoms of meningitis and with the absence of fever which resulted in death 70 days after the onset of symptoms. The patient together with her younger brother was diagnosed at the age of 5 years with familial congenital hypopituitarism, due to homozygous mutation c.150delA in PROP1 gene. Due to evolving hypopituitarism, she was replaced with thyroxine (from age 5), hydrocortisone (from age 13), GH (from age 13 until 17), and sex steroids in adolescence and adulthood. Her consanguineous family has a prominent history of malignant diseases. Six close relatives had malignant disease including her late maternal aunt with breast cancer. BRCA 1 and BRCA 2 mutational analysis in the patient's mother was negative. Histology after autopsy disclosed advanced ovarian cancer with multiple metastases to the brain, leptomeninges, lungs, heart, and adrenals. Low circulating IGF-1 did not seem to protect this patient from cancer initiation and progression in the context of strong family history of malignancies.

    Full Text Available Devi Dayal, Rajendra Prasad Department of Pediatrics, Pediatric Endocrinology and Diabetes Unit, Postgraduate Institute of Medical Education and Research, Chandigarh, India Abstract: Congenital hypothyroidism (CH, the most common pediatric endocrine disorder with an estimated prevalence of 1:2,000 to 1:4,000, is an under-recognized problem in countries without routine newborn screening (NBS programs. Thyroid dysgenesis (TD is the most common cause of primary CH accounting for approximately 85% of all cases; most of the remaining patients have dyshormonogenesis. Transient CH and CH with eutopic gland, are increasingly being identified after introduction of routine NBS. The clinical features of CH are often subtle resulting in delayed diagnosis and eventually poor intellectual outcome. In developed countries, detection by NBS and early initiation of treatment has largely eliminated the intellectual disability caused by this disorder. The lower screening thyroid stimulating hormone (TSH cutoff and changes in birth demographics in some countries have been associated with an increase in the reported incidence of CH. However, the additional cases detected by the lower TSH cutoff tend to have either milder or transient hypothyroidism. Diagnosis of CH is made on the basis of serum concentrations of TSH and thyroxine (T4. Thyroid ultrasound, radionuclide scintigraphy, serum thyroglobulin (TG levels and specific genetic tests help ascertaining the exact etiological diagnosis. Non-availability of later tests should not deter the pediatrician from initiation of treatment. Age at initiation of treatment and starting dose of levothyroxine are critical factors that determine the long-term outcome. Higher doses of levothyroxine at 10–15 µg/kg/day are required in infants, with titration based on T4 and TSH levels, which are repeated frequently. Coexistence of other congenital anomalies in children with CH adds to the morbidity. Approximately 70% of babies

Screening for neonatal CH began in 1970s. The rationale and reason for neonatal screening for CH (NSCH are well established. It is mandatory in most developed countries along with the screen for metabolic disorder. The possibility of measuring TSH and thyroid hormones in cord blood paved the way for newborn screening (NS for CH. Worldwide it is estimated that 25% of the live born population of 130 million babies undergo NSCH. Klein et al., by 1972 had shown improved CNS prognosis in CH treated by age 3 months. NSCH has largely eradicated the severe irreversible neurodevelopmental damage and reversed the chances of growth failure in infancy and early childhood.

    Full Text Available One full-term, dead foetus was successfully removed from a 5-year old, crossbred black and white goat. The goat was stall-fed with green fodder and it delivered two dead foetuses in the previous pregnancy. The foetus had a large swelling in the cranio-ventral neck region. Upon cutting skin, the swelling revealed extremely enlarged thyroid gland having two asymmetrical lobes with the right lobe was 8.10 x 15.0 cm and the left 5.5 x 8.6 cm in size. The skin was devoid of hair, pale-white and thickened with myxedema. Histologically, the enlarged thyroid consisted of colloid goitre and the lungs were oedematous. This case of congenital goitre was unusual and differed from the reported cases in two aspects viz 1 the two lobes were enlarged but unequal and 2 histologically goitre was colloid instead of usual hyperplastic type.

    Nasal airway obstruction is a potentially life-threatening condition in the newborn. Neonates are obligatory nasal breathers. The pyriform aperture is the narrowest, most anterior bony portion of the nasal airway, and a decrease in its cross-sectional area will significantly increase nasal airway resistance. Congenital nasal pyriform aperture stenosis (CNPAS) is a rare, unusual form of nasal obstruction. It should be considered in the differential diagnosis of any neonate or infant with signs and symptoms of upper airway compromise. It is important to differentiate this level of obstruction from the more common posterior choanal stenosis or atresia. CNPAS presents with symptoms of nasal airway obstruction, which are often characterized by episodic apnea and cyclical cyanosis. (orig.)

  6. Adrenal gland infection by serotype 5 adenovirus requires coagulation factors.

    Directory of Open Access Journals (Sweden)

    Lucile Tran

    Full Text Available Recombinant, replication-deficient serotype 5 adenovirus infects the liver upon in vivo, systemic injection in rodents. This infection requires the binding of factor X to the capsid of this adenovirus. Another organ, the adrenal gland is also infected upon systemic administration of Ad, however, whether this infection is dependent on the cocksackie adenovirus receptor (CAR or depends on the binding of factor X to the viral capsid remained to be determined. In the present work, we have used a pharmacological agent (warfarin as well as recombinant adenoviruses lacking the binding site of Factor X to elucidate this mechanism in mice. We demonstrate that, as observed in the liver, adenovirus infection of the adrenal glands in vivo requires Factor X. Considering that the level of transduction of the adrenal glands is well-below that of the liver and that capsid-modified adenoviruses are unlikely to selectively infect the adrenal glands, we have used single-photon emission computed tomography (SPECT imaging of gene expression to determine whether local virus administration (direct injection in the kidney could increase gene transfer to the adrenal glands. We demonstrate that direct injection of the virus in the kidney increases gene transfer in the adrenal gland but liver transduction remains important. These observations strongly suggest that serotype 5 adenovirus uses a similar mechanism to infect liver and adrenal gland and that selective transgene expression in the latter is more likely to be achieved through transcriptional targeting.

    Full Text Available Adrenal incidentalomas are found incidentally during a radiologic examination performed for indications other than an adrenal disease, and 15% of them are bilateral adrenal masses. This study describes a 51-year-old male smoker patient admitted with diabetes mellitus. An abdominal ultrasonography performed due to his anemia revealed bilateral adrenal masses. His chest X-ray showed abnormal 10 cm opacity at the right upper lung, and brain, thorax, and abdomen CT scans showed multiple lesions compatible with lung cancer metastases. The pathological examination of the transthoracic lung biopsy specimen was consistent with lung adenocarcinoma. Findings in this patient indicate that, in middle aged patients with bilateral adrenal mass and a history or finding of any malignancy, the first diagnosis which should be considered is adrenal metastasis, and confirming the diagnosis by adrenal biopsy may be useless. Furthermore, screening all smoking patients by chest X-ray or thoracic CT for lung cancer may not be accepted as a routine procedure, but in smokers admitted to a hospital due to signs and symptoms attributed to a pulmonary disease, at least a chest X-ray should be requested.

    To assess the contribution of adrenal-derived androgens in women with hirsutism, adrenal scintigrams under dexamethasone suppression (DS) were performed on 35 women with increasing facial or body hair and irregular or absent menses. Based upon the DS regimen chosen (8 mg/d for 2 days or 4 md/d for 7 days before the injection of 6..beta..-(/sup 131/I)iodomethylnorcholesterol), three imaging patterns were identified. The first was the absence of uptake before 3 days (8-mg DS) or before 5 days (4-mg DS) after injection. This imaging pattern was seen in 17 of the 35 patients studied and was considered normal. The second pattern was bilateral uptake earlier than 3 days (8-mg DS regimen) or 5 days (4-mg DS) after injection. This was seen in 13 of the 35 patients and was interpreted as bilateral early visualization. Adrenal-vein catheterization performed on six patients with this pattern showed increased adrenal-vein testosterone. The third pattern, observed in five patients, was unilateral early visualization, which in four cases investigated to date was the result of an adrenocortical adenoma. This study confirms the adrenal cortex as a source of androgens in women with hirsutism and hyperandrogenism and demonstrates that DS adrenal scintigraphy can be utilized to identify those women in whom adrenal-derived androgens contribute to their hyperandrogenism.

    Full Text Available Abstract Background Adrenal crisis after surgical procedure is a rare but potentially catastrophic life-threatening event. Its manifestations, such as hypotension, tachycardia, hypoxia, and fever mimic the other more common postoperative complications. Clinical outcome is dependent upon early recognition of the condition and proper management with exogenous steroid administration. Case presentation We report a 75-year-old man who presented with shock immediately after surgery for a femoral fracture from lung cancer metastasis. Anemia and severe hyponatremia were detected. Despite adequate fluid resuscitation, nonspecific symptoms including hypotension, tachycardia, hypoxia, fever and confusion occurred. Emergent CT revealed enlarged bilateral adrenal glands. Under the diagnosis of adrenal crisis due to metastatic infiltration of adrenal glands, the patient was treated with appropriate steroid replacement resulting in rapid improvement and recovery. Conclusion We describe a case of adrenal crisis caused by the lack of adrenal reserve based on metastatic involvement and surgical stress, the first published case of adrenal crisis after surgery for a pathologic fracture from lung cancer metastasis. Surgeons treating pathologic fractures should be aware of this complication and familiar with its appropriate therapy because of increasing opportunity to care patients with metastatic bone tumors due to recent advances in cancer treatment.

    Full Text Available The term adrenal insufficiency refers to the hypofunction of this gland. From the etiologic point of view it may be either primary or secondary. This insufficiency manifests as inadequate serum levels of cortisol and adrenal androgens in the secondary form and of these and mineralocorticoids in the primary one. Clinical manifestations are often nonspecific and, consequently, diagnosis may be difficult to establish and treatment may be delayed with increased morbidity and mortality. This article on adrenal insufficiency includes its definition, epidemiology, etiology, physiopathology, classification, clinical presentation, diagnostic criteria and treatment guidelines. Besides, some special situations like critically ill patients and pregnant women are given special consideration. Emphasis is done on a diagnostic algorithm to make it easier for general practitioners the approach to patients with this endocrine disorder.

    Clinically evident adrenal insufficiency associated with lung cancer is a rare entity. Among reported cases, adrenal insufficiency has occurred with or succeeded the primary lung cancer. Adrenal insufficiency has also been secondary to metastasis to the adrenal gland. The present report concerns a 61-year-old man, a chronic smoker, who presented to us with symptomatic adrenal insufficiency. He had no evidence of lung cancer during this visit. The primary lung cancer was only identified 12 weeks later. Additionally, his adrenals showed no evidence of metastasis. Hence his adrenal insufficiency had been a paraneoplastic manifestation of the lung cancer, and it had also preceded the primary by 12 weeks.

    2010-01-01

    This study assessed adrenal function in patients with paracoccididioidomycosis who had been treated to determine a possible connection between high antibody titers and adrenal dysfunction attributable to persistence of the fungus in adrenal gland. Adrenal gland function was studied in 28 previously treated patients, 2 (7.1%) of whom were shown to have adrenal insufficiency and 7 (259%) who showed a below normal response to stimuli by adrenocorticotropic hormone. Paracoccidioides brasiliensis was detected in the adrenal gland from one of the patients with adrenal insufficiency. Although the study failed to demonstrate a significant difference between high antibody titers and low cortisol levels, the proportion of adrenal insufficiency detected and the subnormal response to adrenocorticotropic hormone confirmed that adrenal damage is an important sequela of paracoccidioidomycosis. Studies with a larger number of patients should be conducted to confirm the hypothesis of persistence of P. brasiliensis in adrenal gland after therapy. PMID:20595488

A right adrenal mass 35/40 mm was revealed during preoperative ultrasound evaluation, which evolved in an adrenal abscess that spontaneously drained 10 days after appendectomy and retrocecal drainage. Adrenal abscesses are exceptionally rare, with only a few cases being reported in the literature, but none of these after acute appendicitis.

    The authors report an uncommon case of bilateral synchronous adrenal gland metastases from left renal cell carcinoma. The diagnosis was established by abdominal ultrasound and computed tomography. The surgical approach initially consisted of left radical nephrectomy and ipsilateral adrenalectomy. Histologically, the tumor of the left adrenal gland was identical to the left renal cell carcinoma. Subsequent contralateral adrenalectomy showed an adrenal metastasis identical to the left renal cell carcinoma. Patient follow-up was good with no recurrence of the disease after one year. This is an uncommon case for renal cancer. The treatment and prognosis are discussed.

    The authors report a case of primary adrenal lymphoma in a 30-year old-female who complained of lumbar pain and was in poor general condition. Ultrasonography and CT scan revealed a heterogeneous mass with necrosis in the left adrenal gland. Non-Hodgkin's lymphoma of B-cell origin was determined by ultrasound-guided aspiration biopsy of the adrenal mass. Taking this case and the findings in the literature into consideration, the features of this disease have been reviewed and the problem of diagnosis, treatment and prognosis have been examined.

  1. Early intervention and management of adrenal insufficiency in children.

    LENUS (Irish Health Repository)

    2012-09-01

    The endocrine disorder adrenal insufficiency includes inadequate production of the steroid hormone cortisol. This results in poor physiological responses to illness, trauma or other stressors and risk of adrenal crisis. Management is based on administration of hydrocortisone. It is important to avoid under- or over-treatment and increase the dosage during times of physiological stress. To reduce morbidity, hospital admissions and mortality, the education and empowerment of parents and carers, and prompt intervention when necessary are essential. A steroid therapy card for adrenal insufficiency containing personal information on a patient\\'s condition was developed for use by families and their specialist centres.

    In this report, images of intense adrenal enhancement in a 79-year-old female patient with right-sided heart failure and severe tricuspid insufficiency are presented. Only two cases of intense adrenal enhancement as a sign of cardiogenic shock were previously reported in the literature. Intense adrenal enhancement could be one of the earliest CT signs of cardiogenic shock. Its presence should be immediately reported to the referring physician as a sign of significant hemodynamic instability warranting early critical-care management.

  4. Oxytocin and hypothalamo-pituitary- adrenal axis

    2010-05-01

    Full Text Available BSTRACT: Upon exposure to different types of stressors, neuroendocrine and behavioral responses that include the activation of the hypothalamus-pituitary-adrenal (HPA axis are given to allow the individuals to cope with stress conditions. It was proven that oxytocin, anonapeptide released from the posterior pituitary, has behavioral and stress-attenuating effects by dampening HPA activity. On the other hand, the neuropeptide was also shown to exert anti-inflammatory effects through the modulation of immune and inflammatory processes in several experimental models of tissue injury. The findings of recent studies suggest that the anti-inflammatory effect of oxytocin depends on its role on HPA axis activity and subsequent release of cortisol. Thus, oxytocin seems to restrain the activity within the HPA-axis, which becomes overactive during many inflammatory processes

    Congenital galactosaemia reveals usually in the second and third weeks of life with a severe liver dysfunction. We report on a case of congenital galactosaemia with, on the one hand, an early onset liver failure, without any free interval, and on the other hand, an hemophagocytic syndrome as a severe secondary outbreak with pulmonary haemorrhage. Appropriate diet led to normalisation of liver function. Hemophagocytosis, probably linked to an associated Klebsiella Pneumoniae sepsis, had a favourable outcome after antibiotic and corticosteroid therapy.

    Full Text Available Cytomegalovirus (CMV is currently the most common agent of congenital infection and the leading infectious cause of brain damage and hearing loss in children. Symptomatic congenital CMV infections usually result from maternal primary infection during early pregnancy. One half of symptomatic infants have cytomegalic inclusion disease (CID, which is characterized by involvement of multiple organs, in particular, the reticuloendothelial and central nervous system (CNS. Moreover, such involvement may or may not include ocular and auditory damage. Approximately 90% of infants with congenital infection are asymptomatic at birth. Preterm infants with perinatal CMV infection can have symptomatic diseases such as pneumonia, hepatitis, and thrombocytopenia. Microcephaly and abnormal neuroradiologic imaging are associated with a poor prognosis. Hearing loss may occur in both symptomatic and asymptomatic infants with congenital infection and may progress through childhood. Congenital infection is defined by the isolation of CMV from infants within the first 3 weeks of life. Ganciclovir therapy can be considered for infants with symptomatic congenital CMV infection involving the CNS. Pregnant women of seronegative state should be counseled on the importance of good hand washing and other control measures to prevent CMV infection. Heat treatment of infected breast milk at 72?#608;for 5 seconds can eliminate CMV completely.

    AIM: To study the clinical characteristics, diagnosis and surgical treatment of congenital bronchoesophageal fistulae in adults. METHODS: Eleven adult cases of congenital bronchoesophageal fistula diagnosed and treated in our hospital between May 1990 and August 2010 were reviewed. Its clinical presentations, diagnostic methods, anatomic type, treatment, and follow-up were recorded. RESULTS: Of the chief clinical presentations, nonspecific cough and sputum were found in 10 (90.9%), recurrent bouts of cough after drinking liquid food in 6 (54.6%), hemoptysis in 6 (54.6%), low fever in 4 (36.4%), and chest pain in 3 (27.3%) of the 11 cases, respectively. The duration of symptoms before diagnosis ranged 5-36.5 years. The diagnosis of congenital bronchoesophageal fistulae was established in 9 patients by barium esophagography, in 1 patient by esophagoscopy and in 1 patient by bronchoscopy, respectively. The congenital bronchoesophageal fistulae communicated with a segmental bronchus, a main bronchus, and an intermediate bronchus in 8, 2 and 1 patients, respectively. The treatment of congenital bronchoesophageal fistulae involved excision of the fistula in 10 patients or division and suturing in 1 patient. The associated lung lesion was removed in all patients. No long-term sequelae were found during the postoperative follow-up except in 1 patient with bronchial fistula who accepted reoperation before recovery. CONCLUSION: Congenital bronchoesophageal fistula is rare in adults. Its most useful diagnostic method is esophagography. It must be treated surgically as soon as the diagnosis is established.

Peirce (1839-1914 and William James (1842-1910. I will start with a basic characterization of classical pragmatism; then, I shall examine certain conceptions in Peirce's and James' pragmatism, in order to establish affinities with Davidson´s thought. Finally, and bearing in mind the previous con-nections, I will reflect briefly on the relevance –often unrecognized- of classical pragmatist ideas in the context of contemporary philosophi-cal discussions.

    2008-05-01

    Full Text Available Abstract Background To identify the biochemical changes induced by sleep deprivation at a proteomic level, we compared the hippocampal proteome of rats either after 4 hours of sleep or sleep deprivation obtained by gentle handling. Because sleep deprivation might induce some stress, we also analyzed proteomic changes in rat adrenals in the same conditions. After sleep deprivation, proteins from both tissues were extracted and subjected to 2D-DIGE analysis followed by protein identification through mass spectrometry and database search. Results In the hippocampus, 87 spots showed significant variation between sleep and sleep deprivation, with more proteins showing higher abundance in the latter case. Of these, 16 proteins were present in sufficient amount for a sequencing attempt and among the 12 identified proteins, inferred affected cellular functions include cell metabolism, energy pathways, transport and vesicle trafficking, cytoskeleton and protein processing. Although we did not observe classical, macroscopic effect of stress in sleep-deprived rats, 47 protein spots showed significant variation in adrenal tissue between sleep and sleep deprivation, with more proteins showing higher abundance following sleep. Of these, 16 proteins were also present in sufficient amount for a sequencing attempt and among the 13 identified proteins, the most relevant cellular function that was affected was cell metabolism. Conclusion At a proteomic level, short term sleep deprivation is characterized by a higher expression of some proteins in the hippocampus and a lower abundance of other proteins in the adrenals (compared to normal sleep control. Altogether, this could indicate a general activation of a number of cellular mechanisms involved in the maintenance of wakefulness and in increased energy expenditure during sleep deprivation. These findings are relevant to suggested functions of sleep like energy repletion and the restoration of molecular stocks or

    We have characterized a specific binding site for angiotensin IV in bovine adrenal cortex membranes. Pseudo-equilibrium studies at 37 degrees C for 2 h have shown that this binding site recognizes angiotensin IV with a high affinity (Kd = 0.24 +/- 0.03 nM). The binding site is saturable and relatively abundant (maximal binding capacity around 0.5 pmol/mg protein). Non-equilibrium kinetic analyses at 37 degrees C revealed a calculated kinetic Kd of 47 pM. The binding site is pharmacologically distinct from the classic angiotensin receptors AT1 or AT2. Competitive binding studies with bovine adrenal cortex membranes demonstrated the following rank order of effectiveness: angiotensin IV (Val-Tyr-Ile-His-Pro-Phe) = angiotensin II-(3-7) (Val-Tyr-Ile-His-Pro) > angiotensin III (Arg-Val-Tyr-Ile-His-Pro-Phe) > or = angiotensin II-(4-7) (Tyr-Ile-His-Pro) > angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe) > angiotensin II-(1-6) (Asp-Arg-Val-Tyr-Ile-His) > angiotensin II-(4-8) (Tyr-Ile-His-Pro-Phe) > > > angiotensin II-(3-6) (Val-Tyr-Ile-His), angiotensin II-(4-6) (Tyr-Ile-His), L-158,809 (5,7-dimethyl-2-ethyl-3-[(2'(1-H-tetrazol-5-yl)[1,1'-biphenyl]-4-y l) methyl]-3-H-imidazo[4,5-beta]pyridine H2O) and PD 123319 (1-[4-(dimethylamino)3-methylphenyl]methyl-5-(diphenylacetyl)4,5,6 ,7- tetrahydro-1H-imidazo[4,5-c]pyridine-6-carboxylic acid).

    Female classic galactosemia patients suffer from primary ovarian insufficiency (POI). The cause for this long-term complication is not fully understood. One of the proposed mechanisms is that hypoglycosylation of complex molecules, a known secondary phenomenon of galactosemia, leads to FSH dysfunction. An earlier study showed less acidic isoforms of FSH in serum samples of two classic galactosemia patients compared to controls, indicating hypoglycosylation. In this study, FSH isoform patterns of five classic galactosemia patients with POI were compared to the pattern obtained in two patients with a primary glycosylation disorder (phosphomannomutase-2-deficient congenital disorders of glycosylation, PMM2-CDG) and POI, and in five postmenopausal women as controls. We used FPLC chromatofocussing with measurement of FSH concentration per fraction, and discovered that there were no significant differences between galactosemia patients, PMM2-CDG patients and postmenopausal controls. Our results do not support that FSH dysfunction due to a less acidic isoform pattern because of hypoglycosylation is a key mechanism of POI in this disease.

    Full Text Available Introduction: We report a case of acute adrenal insufficiency (AAI in a patient with antiphospholipid syndrome (APS. Case Report: A 44-year-old female patient presented to us with acute abdominal pain associated with recurrent vomiting and giddiness. On examination, her blood pressure was 80/50 mm Hg. Systemic examination was normal. Further evaluation revealed hypocortisolemia with elevated plasma adrenocorticotropin hormone indicative of primary adrenal insufficiency. Her abdominal computed tomography scan showed features of evolving bilateral adrenal infarction. Etiological work-up revealed prolonged activated thromboplastin time, which didn′t correct with normal plasma, her anti-cardiolipin antibody and lupus anticoagulant were also positive. She was diagnosed to have APS with adrenal insufficiency and she was started on intravenous steroids and heparin infusion. Conclusion: AAI due to the APS can present with acute abdominal pain followed by hypotension. A high index of suspicion is needed to make the correct diagnosis and to initiate appropriate treatment.

    Of the six GATA transcription factors, GATA-4 and GATA-6 are expressed in the mouse and human adrenal with distinct developmental profiles. GATA-4 is confined to the fetal cortex, i.e. to the less differentiated proliferating cells, while GATA-6 is expressed both in the fetal and adult adrenal. In vitro, GATA-4 regulates inhibin-alpha and steroidogenic factor-1 implicated in normal adrenal function. GATA-6 probably has roles in the development and differentiation of adrenocortical cells, and in the regulation of steroidogenesis. GATA-4 expression is dramatically upregulated and GATA-6 downregulated in gonadotropin dependent mouse adrenocortical tumors. This is accompanied by the appearance of luteinizing hormone receptor (LHR). In vitro, GATA-4 transactivates LHR promoter, and gonadotropins upregulate GATA-4 levels. Human adrenal tumors occasionally express GATA-4, whereas GATA-6 levels are usually lower than normal.

    Plasma corticosterone and ACTH concentrations were determined in neonatal rats 1, 7, 14, and 21 days old, under a variety of experimental conditions, to obtain more information on the postnatal development of the rat hypothalamo-adrenal (HHA) axis. The results indicate that: (1) there is a diminution followed by an increase in responsiveness of the adrenal gland, but the pituitary response to direct hormonal stimulation is unchanged during the first three postnatal weeks; (2) continued stimulation of the adrenal by ACTH or of the central nervous system (CNS) or hypothalamus by corticosterone is necessary during early postnatal development to allow normal maturation of the HHA axis; and (3) feedback inhibition is operative by birth, at least to a moderate degree. Taken together, the studies suggest that both the adrenal and pituitary glands are potentially functional at birth, but that the hypothalamic and CNS mediators of the stress response are not mature until at least the second or third postnatal week.

    Numerous studies have shown that the hypothalamic-pituitary-adrenal (HPA) axis is hyperactive in some depressed patients. It is unclear whether such hyperactivity results in changed volumes of the adrenal glands, pituitary gland and hypothalamus. We systematically reviewed all controlled studies...... on the adrenal or pituitary glands or hypothalamus volume in unipolar depressive disorder published in PubMed 1966 to December 2009. We identified three studies that investigated the volume of the adrenal glands and eight studies that examined the volume of the pituitary gland, but no studies on hypothalamus...... identified such as small population samples, different subtypes of depression and insufficient matching of patients and controls. Due to large heterogeneity of study designs and data, it was futile to make a meta-analysis. It is concluded that it remains unclear whether hyperactivity of the HPA axis results...

    2009-01-01

    Contemporary quantum field theory is mainly developed as quantization of classical fields. Therefore, classical field theory and its BRST extension is the necessary step towards quantum field theory. This book aims to provide a complete mathematical foundation of Lagrangian classical field theory and its BRST extension for the purpose of quantization. Based on the standard geometric formulation of theory of nonlinear differential operators, Lagrangian field theory is treated in a very general setting. Reducible degenerate Lagrangian theories of even and odd fields on an arbitrary smooth manifold are considered. The second Noether theorems generalized to these theories and formulated in the homology terms provide the strict mathematical formulation of BRST extended classical field theory

    2001-08-01

    Recent advances in and controversies concerning the management of children with congenital valvular aortic stenosis are discussed. In neonates with critical aortic stenosis, improved survival has recently been reported after surgical open valvotomy and balloon valvuloplasty, although it is difficult at this point to compare the results of the two procedures and determine their differential indications. Good results have also been achieved after extended aortic valvuloplasty for recurrent aortic stenosis and/or insufficiency, but the length of follow-up in these patients is still short. The technique first reported in 1991 for bilateral enlargement fo a small annulus permits the insertion of an aortic valve 3-4 sizes larger than the native annulus. It entails no risk of distorting the mitral valve, damaging the conduction system or important branches of the coronary arteries, or resulting in left ventricular dysfunction. The Ross procedure is now widely applied in the West, with reports of early mortality rates of less than 5% and event-free survival rates of 80-90% during follow-up of 4-8 years. Longer follow-up and continued careful evaluation are required to resolve the issue of possible dilatation and subsequent neoaortic valve dysfunction and pulmonary stenosis due to allograft degeneration after pulmonary autograft root replacement in children.

    Full Text Available Parotid fistula is a cause of great distress and embarrassment to the patient. Parotid fistula is most commonly a post-traumatic situation. Congenital parotid salivary fistulas are unusual entities that can arise from accessory parotid glands or even more infrequently, from normal parotid glands through an aberrant Stensen′s duct. The treatment of fistulous tract is usually surgical and can be successfully excised after making a skin incision along the skin tension line around the fistula opening. This report describes a case of right accessory parotid gland fistula of a 4-year-old boy with discharge of pus from right cheek. Computed tomography (CT fistulography and CT sialography demonstrated fistulous tract arising from accessory parotid gland. Both CT fistulography and CT sialography are very helpful in the diagnosis and surgical planning. In this case, superficial parotidectomy is the treatment of choice. A detailed history, clinical and functional examination, proper salivary gland investigations facilitates in correct diagnosis followed by immediate surgical intervention helps us to restore physical, psychological health of the child patient.

  9. Congenital hyperthyroidism: autopsy report

    1999-01-01

    Full Text Available We report the autopsy of a stillborn fetus with congenital hyperthyroidism born to a mother with untreated Graves' disease, whose cause of death was congestive heart failure. The major findings concerned the skull, thyroid, heart, and placenta. The cranial sutures were closed, with overlapping skull bones. The thyroid was increased in volume and had intense blood congestion. Histological examination showed hyperactive follicles. The heart was enlarged and softened, with dilated cavities and hemorrhagic suffusions in the epicardium. The placenta had infarctions that involved at least 20% of its surface, and the vessels of the umbilical cord were fully exposed due to a decrease in Wharton 's jelly. Hyperthyroidism was confirmed by the maternal clinical data, the fetal findings of exophthalmia, craniosynostosis, and goiter with signs of follicular hyperactivity. Craniosynostosis is caused by the anabolic action of thyroid hormones in bone formation during the initial stages of development. The delayed initiation of treatment in the present case contributed to the severity of fetal hyperthyroidism and consequent fetal death.

    2006-10-01

    Full Text Available Abstract Congenital pulmonary lymphangiectasia (PL is a rare developmental disorder involving the lung, and characterized by pulmonary subpleural, interlobar, perivascular and peribronchial lymphatic dilatation. The prevalence is unknown. PL presents at birth with severe respiratory distress, tachypnea and cyanosis, with a very high mortality rate at or within a few hours of birth. Most reported cases are sporadic and the etiology is not completely understood. It has been suggested that PL lymphatic channels of the fetal lung do not undergo the normal regression process at 20 weeks of gestation. Secondary PL may be caused by a cardiac lesion. The diagnostic approach includes complete family and obstetric history, conventional radiologic studies, ultrasound and magnetic resonance studies, lymphoscintigraphy, lung functionality tests, lung biopsy, bronchoscopy, and pleural effusion examination. During the prenatal period, all causes leading to hydrops fetalis should be considered in the diagnosis of PL. Fetal ultrasound evaluation plays a key role in the antenatal diagnosis of PL. At birth, mechanical ventilation and pleural drainage are nearly always necessary to obtain a favorable outcome of respiratory distress. Home supplemental oxygen therapy and symptomatic treatment of recurrent cough and wheeze are often necessary during childhood, sometimes associated with prolonged pleural drainage. Recent advances in intensive neonatal care have changed the previously nearly fatal outcome of PL at birth. Patients affected by PL who survive infancy, present medical problems which are characteristic of chronic lung disease.

    2012-01-01

    Congenital Diaphragmatic Hernia (CDH) is defined by the presence of an orifice in the diaphragm, more often left and posterolateral that permits the herniation of abdominal contents into the thorax. The lungs are hypoplastic and have abnormal vessels that cause respiratory insufficiency and persistent pulmonary hypertension with high mortality. About one third of cases have cardiovascular malformations and lesser proportions have skeletal, neural, genitourinary, gastrointestinal or other defects. CDH can be a component of Pallister-Killian, Fryns, Ghersoni-Baruch, WAGR, Denys-Drash, Brachman-De Lange, Donnai-Barrow or Wolf-Hirschhorn syndromes. Some chromosomal anomalies involve CDH as well. The incidence is < 5 in 10,000 live-births. The etiology is unknown although clinical, genetic and experimental evidence points to disturbances in the retinoid-signaling pathway during organogenesis. Antenatal diagnosis is often made and this allows prenatal management (open correction of the hernia in the past and reversible fetoscopic tracheal obstruction nowadays) that may be indicated in cases with severe lung hypoplasia and grim prognosis. Treatment after birth requires all the refinements of critical care including extracorporeal membrane oxygenation prior to surgical correction. The best hospital series report 80% survival but it remains around 50% in population-based studies. Chronic respiratory tract disease, neurodevelopmental problems, neurosensorial hearing loss and gastroesophageal reflux are common problems in survivors. Much more research on several aspects of this severe condition is warranted. PMID:22214468

  12. Imaging of Adrenal Masses with Emphasis on Adrenocortical Tumors

    Full Text Available Because of the more widespread and frequent use of cross-sectional techniques, mainly computed tomography (CT, an increasing number of adrenal tumors are detected as incidental findings (“incidentalomas”. These incidentaloma patients are much more frequent than those undergoing imaging because of symptoms related to adrenal disease. CT and magnetic resonance imaging (MRI are in most patients sufficient for characterization and follow-up of the incidentaloma. In a minor portion of patients, biochemical screening reveals a functional tumor and further diagnostic work-up and therapy need to be performed according to the type of hormonal overproduction. In oncological patients, especially when the morphological imaging criteria indicate an adrenal metastasis, biopsy of the lesion should be considered after pheochromocytoma is ruled out biochemically. In the minority of patients in whom CT and MRI fail to characterize the tumor and when time is of essence, functional imaging mainly by positron emission tomography (PET is available using various tracers. The most used PET tracer, [18F]fluoro-deoxy-glucose (18FDG, is able to differentiate benign from malignant adrenal tumors in many patients. 11C-metomidate (11C-MTO is a more specialized PET tracer that binds to the 11-beta-hydroxylase enzyme in the adrenal cortex and thus makes it possible to differ adrenal tumors (benign adrenocortical adenoma and adrenocortical cancer from those of non-adrenocortical origin.

    Background Airway symptoms in asthma are related to decrease of epinephrine secretion, which may be ascribed to elevated nerve growth factor (NGF) in the organism.The aim of this study was to monitor the neuroendocrine alteration in the adrenal medulla of asthmatic rats.Methods Sixteen rats were randomly divided into two groups (n=8), control group and asthma group, and the asthmatic rats were sensitized and challenged with ovalbumin (OVA).The levels of NGF, epinephrine and norepinephrine in serum were detected by enzyme linked immunosorbent assay (ELISA), the NGF expression in adrenal medulla was detected by immunohistochemistry, and the changes in the ultrastructure of the adrenal medulla was observed by electron microscopy.Results The NGF expression was increased in asthmatic rats compared with control rats.Compared with control rats,the results indicated that the epinephrine level was decreased in asthmatic rats, but no significant difference was found in norepinephrine levels.We found more ganglion cells in the adrenal medulla of asthmatic rats than in control rats, with NGF immunostaining mainly located in these ganglion cells.Electron microscopic images showed the density of chromaffin granula decreased and there was shrunken nucleolemma in the adrenal medullary cells of asthmatic rats.Conclusion The innervation of the adrenal medulla is changed in asthmatic rats, and it may contribute to the epinephrine decrease in asthma.

    The formation of adrenocortical zonation occurs in rats during late gestation. Since adult cortical function is modulated by neural mediators, it is possible that the development of differentiated function is dependent on cortical innervation. The goal of this study was to compare the pattern and timing of rodent and ovine adrenal innervation during late organogenesis by staining with antibodies directed against the neuropeptides vasoactive intestinal peptide (VIP), calcitonin gene-related peptide (CGRP) and neuropeptide tyrosine (NPY) and the catecholamine biosynthetic enzyme, tyrosine hydroxylase (TOH). Rat adrenals were collected from fetal days 17-21 (term=21 days) and ovine adrenals from fetal days 101-136 (term=145 days). Adrenals were fixed, cryosectioned at 100 microns and immunostained using Cy3-conjugated secondary antibodies. In both species, staining of VIP, CGRP, NPY and TOH fibers was observed in the capsule and subcapsular layers of the cortex during gestation. In late gestation, VIP- and NPY-positive ganglions cells were observed near the medulla extending processes toward the outer cortex; in ovine adrenals, fibers from ganglion cells appeared to surround nests of outer cortical (presumably, zona glomerulosa) cells. These data show that phenotypically distinct neural elements appear at different stages of adrenocortical development. The presence of neural elements in contact with adrenal cortical cells supports the possibility for neural control of adrenocortical development.

    We report a case of 78-year old man who presented with symptoms of adrenal insufficiency. The computed tomography (CT) scan showed the presence of bilateral adrenal masses. A CT-scan guided needle biopsy revealed diffuse large- B cell lymphoma. The absence of pathological findings in clinical, bone marrow and CT scan examinations supported the diagnosis of primary non-Hodgkin Lymphoma of the adrenal glands. The patient was treated with four cycles of R-CHOP chemotherapy with Rituximab, liposomal Doxorubicin, Cyclophosphamide, Vincristine and Prednisolone. At the end of fourth cycle there was radiological improvement but the chemotherapy was stopped because of IV grade toxicity. He completed treatment with radiotherapy of right adrenal mass. Few days after finishing radiation therapy the patient died due to a disseminated infection. No progressive disease was founded.

    Objective Prednisolone is used as glucocorticoid replacement therapy for adrenal insufficiency (AI). Recent data indicate that its use in AI is associated with low bone mineral density. Data on risk factors for cardiovascular disease in patients with AI treated with prednisolone are scarce, despite this condition being the predominant cause of excess mortality. We aimed to address this question using real-world data from the European Adrenal Insufficiency Registry (EU-AIR). Design/methods EU-AIR, comprising of 19 centres across Germany, the Netherlands, Sweden and the UK, commenced enrolling patients with AI in August 2012. Patients receiving prednisolone (3–6 mg/day, n = 50) or hydrocortisone (15–30 mg/day, n = 909) were identified and grouped at a ratio of 1:3 (prednisolone:hydrocortisone) by matching for gender, age, duration and type of disease. Data from baseline and follow-up visits were analysed. Data from patients with congenital adrenal hyperplasia were excluded. Results Significantly higher mean ± s.d. total (6.3 ± 1.6 vs 5.4 ± 1.1 mmol/L; P = 0.003) and low-density lipoprotein (LDL) cholesterol levels (3.9 ± 1.4 vs 3.2 ± 1.0 mmol/L; P = 0.013) were identified in 47 patients on prednisolone vs 141 receiving hydrocortisone at baseline and at follow-up (P = 0.005 and P = 0.006, respectively). HbA1c, high-density lipoprotein and triglyceride levels, body mass index, systolic and diastolic blood pressure and waist circumference were not significantly different. Conclusions This is the first matched analysis of its kind. Significantly higher LDL levels in patients receiving prednisolone relative to hydrocortisone could predict a higher relative risk of cardiovascular disease in the former group. PMID:27864317

    Adrenal crisis is a life-threatening emergency that causes significant excess mortality in patients with adrenal insufficiency. Delayed recognition by medical staff of an impending adrenal crisis and failure to give timely hydrocortisone therapy within the emergency department continue to be commonly encountered, even in metropolitan teaching hospitals. Within the authors' institutions, several cases of poorly handled adrenal crises have occurred over the last 2 years. Anecdotal accounts from members of the Addison's support group suggest that these issues are common in Australia. This manuscript is a timely reminder for clinical staff on the critical importance of the recognition, treatment and prevention of adrenal crisis. The manuscript: (i) outlines a case and the clinical outcome of sub-optimally managed adrenal crisis, (ii) summarises the clinical features and acute management of adrenal crisis, (iii) provides recommendations on the prevention of adrenal crisis and (iv) provides guidance on the management of 'sick days' in patients with adrenal insufficiency.

  18. The Role of gsp Mutations on the Development of Adrenal Cortical Tumors and Adrenal Hyperplasias

    2016-07-01

    Full Text Available Somatic GNAS point mutations, commonly known as gsp mutations, are involved in the pathogenesis of McCune Albright syndrome and have also been described in autonomous hormone-producing tumors, such as somatotropinoma, corticotrophoma, thyroid cancer, ovarian and testicular Leydig cell tumors and primary macronodular adrenocortical hyperplasia (PMAH. [1-3]The involvement of gsp mutations in adrenal tumors was first described by Lyons et al. in 1990. Since then, several studies have detected the presence of gsp mutations in adrenal tumors, but none of them could explain its presence along or the mechanism that leads to tumor formation and hormone hypersecretion. As a result, the molecular pathogenesis of the majority of sporadic adrenocortical tumors remains unclear. [3] PMAH has also been reported with gsp somatic mutations in a few cases. Fragoso et al. in 2003 identified two distinct gsp somatic mutations affecting arginine residues on codon 201 of GNAS in a few patients with PMAH who lacked any features or manifestations of McCune Albright syndrome. Followed by this discovery, other studies have continued looking for gsp mutations based on strong prior evidence demonstrating that increased cAMP signaling is sufficient for cell proliferation and cortisol production. [2, 4] With consideration for the previously reported findings, we conjecture that although somatic activating mutations in GNAS are a rare molecular event, these mutations could probably be sufficient to induce the development of macronodule hyperplasia and variable cortisol secretion.In this manuscript, we revised the presence of gsp mutations associated with adrenal cortical tumors and hyperplasia.

  19. Congenital Scoliosis (Mini-review).

    Weiss, Hans-Rudolf; Moramarco, Marc

    2016-01-01

    Congenital scoliosis is a lateral deformity of the spine with a disturbance of the sagittal profile caused by malformations of vertebra and ribs. Typically, early surgical intervention is the suggested treatment (before three-years-old) for young patients with congenital scoliosis. While a previous study was conducted in 2011 to investigate long-term studies supporting the necessity for this recommendation and no evidence was found, this current review, is an updated search for evidence published from 2011 through March 2015. This also failed to find any prospective or randomized controlled studies to support the hypothesis that spinal fusion surgery in patients with congenital scoliosis should be considered as evidence-based treatment. Contradictory results exist on the safety of hemivertebra resection and segmental fusion using pedicle screw fixation. When using the VEPTR (vertical expandable prosthetic titanium rib) device, studies show a high rate of complications exist. It is difficult to predict the final outcome for patients with congenital scoliosis. However, it is possible that many patients with congenital scoliosis may be able to avoid spinal surgery with the application of advanced bracing technology. Therefore, it is only prudent to advocate for conservative management first before spinal surgery is considered.

  20. [Adrenal tumors as a cause of hypertension].

    Science.gov (United States)

    Grimaldi, Franco

    2010-01-01

    Hypertension is one of the main risk factors for cardiovascular diseases, which today are the primary cause of mortality in developed countries. To decrease the mortality and morbidity due to cardiovascular disease, it is necessary to treat hypertension correctly on the basis of an accurate diagnosis. A secondary cause of hypertension must be suspected if it is severe or resistant to treatment, if there is a sudden increase in blood pressure in a patient hitherto well controlled, or if it develops in childhood or in a person under 30 years of age, especially if not obese and without a family history of hypertension. In these instances the frequency of hypertension varies from 1-5% for mild to moderate to 10-20% for severe or refractory hypertension. One of the principal causes of secondary hypertension is related to adrenal gland tumors or dysfunctions such as Cushing's syndrome, primary aldosteronism (Conn's syndrome) and pheochromocytoma. This paper will discuss the clinical presentation and diagnostic tests pertinent to these neoplasms, organ damage assessment, utilization of imaging techniques, and the medical and surgical options.

    Adrenal histoplasmosis is one of the most common adrenal granulomatous infections in endemic areas. Although CT or MRI findings of adrenal histoplasmosis have been documented, there are no reports regarding {sup 18}F-fluorodeoxyglocose (FDG) positron emission tomography (PET) findings. We report a case of bilateral adrenal histoplasmosis showing a significantly high uptake of {sup 18}F-fluorodeoxyglocose on PET study. Adrenal histoplasmosis should be considered as one of the differential diagnoses in cases of adrenal tumors with intense FDG uptake, even in non-endemic areas. (orig.)

    Primary adrenal lymphoma is extremely rare. We report a young patient who presented with non- specific symptoms of fever and abdominal pain. Conventional imaging modalities demonstrated bilateral bulky adrenal masses, and whole-body fluorine-18-fluorodesoxyglucose ((18)F-FDG) positron emission tomography/computed tomography showed intense (18)F-FDG-avid bilateral adrenal masses with no evidence of extra-adrenal spread. A pathological diagnosis of non-Hodgkin lymphoma of peripheral T-cell type was made. The present case indicates that primary adrenal lymphoma should be included in the differential diagnosis of bilateral adrenal masses.

    2013-11-01

    Full Text Available Modern radiological technology has transformed the way that adrenal lesions are currently investigated. The contemporary radiologist has been catapulted to the forefront in the management of adrenal disease. With the increasing use of cross-sectional imaging, adrenal lesions are being serendipitously discovered in radiological studies undertaken for non-adrenal-related conditions – the so-called adrenal ‘incidentaloma’. This review discusses the imaging modalities available for characterising these lesions, highlighting current concepts and controversies in differentiating benign from malignant pathology. The article also provides a brief overview of the spectrum of adrenal pathology commonly encountered in the adult population.

  8. Discrete Classical Electromagnetic Fields

    CERN Document Server

    De Souza, M M

    1997-01-01

    The classical electromagnetic field of a spinless point electron is described in a formalism with extended causality by discrete finite transverse point-vector fields with discrete and localized point interactions. These fields are taken as a classical representation of photons, ``classical photons". They are all transversal photons; there are no scalar nor longitudinal photons as these are definitely eliminated by the gauge condition. The angular distribution of emitted photons coincides with the directions of maximum emission in the standard formalism. The Maxwell formalism and its standard field are retrieved by the replacement of these discrete fields by their space-time averages, and in this process scalar and longitudinal photons are necessarily created and added. Divergences and singularities are by-products of this averaging process. This formalism enlighten the meaning and the origin of the non-physical photons, the ones that violate the Lorentz condition in manifestly covariant quantization methods.

  9. Between classical and quantum

    Landsman, N P

    2005-01-01

    The relationship between classical and quantum theory is of central importance to the philosophy of physics, and any interpretation of quantum mechanics has to clarify it. Our discussion of this relationship is partly historical and conceptual, but mostly technical and mathematically rigorous, including over 500 references. On the assumption that quantum mechanics is universal and complete, we discuss three ways in which classical physics has so far been believed to emerge from quantum physics, namely in the limit h -> 0 of small Planck's constant (in a finite system), in the limit of a large system, and through decoherence and consistent histores. The first limit is closely related to modern quantization theory and microlocal analysis, whereas the second involves methods of C*-algebras and the concepts of superselection sectors and macroscopic observables. In these limits, the classical world does not emerge as a sharply defined objective reality, but rather as an approximate appearance relative to certain "...

  10. Randomness: Quantum versus classical

    Khrennikov, Andrei

    2016-05-01

    Recent tremendous development of quantum information theory has led to a number of quantum technological projects, e.g. quantum random generators. This development had stimulated a new wave of interest in quantum foundations. One of the most intriguing problems of quantum foundations is the elaboration of a consistent and commonly accepted interpretation of a quantum state. Closely related problem is the clarification of the notion of quantum randomness and its interrelation with classical randomness. In this short review, we shall discuss basics of classical theory of randomness (which by itself is very complex and characterized by diversity of approaches) and compare it with irreducible quantum randomness. We also discuss briefly “digital philosophy”, its role in physics (classical and quantum) and its coupling to the information interpretation of quantum mechanics (QM).

    2017-01-01

    Background and aim The cysts may potentially affect any organ; adrenals cysts are rare. This is a review of the literature regarding adrenal cysts, focusing on children and young adults. General data Three major types have been described: pure cysts (endothelial, epithelial, and hemorrhagic or pseudocyst), parasitic (as hydatid) cysts and cystic part of a tumour (most frequent are neuroblastoma, ganglioneuroma, pheocromocytoma, and teratoma). The complications are: bleeding, local pressure effects; infection; rupture (including post-traumatic); arterial hypertension due to renal vessels compression. Adrenal hemorrhage represents a particular condition associating precipitating factors such as: coagulation defects as Factor IX or X deficiency, von Willebrand disease, thrombocytopenia; antiphospholipid syndrome; previous therapy with clopidogrel or corticosteroids; the rupture of a prior tumour. At birth, the most suggestive features are abdominal palpable mass, anemia, and persistent jaundice. Adrenal insufficiency may be found especially in premature delivery. The hemorrhage is mostly self-limiting. Antenatal ultrasound diagnosis of a cyst does not always predict the exact pathology result. The most important differential diagnosis of adrenal hemorrhage/hemorrhagic cyst is cystic neuroblastoma which is highly suggestive in the presence of distant metastases and abnormal catecholamine profile. The major clue to differentiate the two conditions is the fact that the tumor is stable or increases over time while the adrenal hemorrhage is expected to remit within one to two weeks. Conclusion Pediatric adrenal cysts vary from simple cysts with a benign behavior to neoplasia- related lesions displaying severe prognosis as seen in cystic neuroblastoma. A multidisciplinary team is required for their management which is conservative as close follow-up or it makes necessary different surgical procedures in cases with large masses or if a malignancy suspicion is presented

  12. Evidence of adrenal failure in aging Dax1-deficient mice.

    Scheys, Joshua O; Heaton, Joanne H; Hammer, Gary D

    2011-09-01

    Dosage-sensitive sex reversal, adrenal hypoplasia congenita (AHC) critical region on the X chromosome, gene 1 (Dax1) is an orphan nuclear receptor essential for development and function of the mammalian adrenal cortex and gonads. DAX1 was cloned as the gene responsible for X-linked AHC, which is characterized by adrenocortical failure necessitating glucocorticoid replacement. Contrary to these human data, young mice with genetic Dax1 knockout (Dax1(-/Y)) exhibit adrenocortical hyperfunction, consistent with the historic description of Dax1 as a transcriptional repressor that inhibits steroidogenic factor 1-dependent steroidogenesis. This paradox of molecular function and two apparently opposite phenotypes associated with Dax1 deficiency in mice and humans is compounded by the recent observations that under certain circumstances, Dax1 can serve as a transcriptional activator of steroidogenic factor 1. The recently revealed role of Dax1 in embryonic stem cell pluripotency, together with the observation that its expression in the adult adrenal is restricted to the subcapsular cortex, where presumptive undifferentiated progenitor cells reside, has led us to reexamine the phenotype of Dax1(-/Y) mice in order to reconcile the conflicting mouse and human data. In this report, we demonstrate that although young Dax1(-/Y) mice have enhanced steroidogenesis and subcapsular adrenocortical proliferation, as these mice age, they exhibit declining adrenal growth, decreasing adrenal steroidogenic capacity, and a reversal of their initial enhanced hormonal sensitivity. Together with a marked adrenal dysplasia in aging mice, these data reveal that both Dax1(-/Y) mice and patients with X-linked AHC exhibit adrenal failure that is consistent with adrenocortical subcapsular progenitor cell depletion and argue for a significant role of Dax1 in maintenance of these cells.

    2016-01-01

    This book guides undergraduate students in the use of Maxima—a computer algebra system—in solving problems in classical mechanics. It functions well as a supplement to a typical classical mechanics textbook. When it comes to problems that are too difficult to solve by hand, computer algebra systems that can perform symbolic mathematical manipulations are a valuable tool. Maxima is particularly attractive in that it is open-source, multiple-platform software that students can download and install free of charge. Lessons learned and capabilities developed using Maxima are easily transferred to other, proprietary software.

  16. Covariantizing Classical Field Theories

    CERN Document Server

    López, Marco Castrillón

    2010-01-01

    We show how to enlarge the covariance group of any classical field theory in such a way that the resulting "covariantized" theory is 'essentially equivalent' to the original. In particular, our technique will render any classical field theory generally covariant, that is, the covariantized theory will be spacetime diffeomorphism-covariant and free of absolute objects. Our results thus generalize the well-known parametrization technique of Dirac and Kucha\\v{r}. Our constructions apply equally well to internal covariance groups, in which context they produce natural derivations of both the Utiyama minimal coupling and St\\"uckelberg tricks.

    2016-01-01

    In this work, we introduce classical holographic codes. These can be understood as concatenated probabilistic codes and can be represented as networks uniformly covering hyperbolic space. In particular, classical holographic codes can be interpreted as maps from bulk degrees of freedom to boundary degrees of freedom. Interestingly, they are shown to exhibit features similar to those expected from the AdS/CFT correspondence. Among these are a version of the Ryu-Takayanagi formula and intriguing properties regarding bulk reconstruction and boundary representations of bulk operations. We discuss the relation of our findings with expectations from AdS/CFT and, in particular, with recent results from quantum error correction.
