    We report on a black male child with congenital hypoplasia of the adrenal gland (CHA) with a de novo duplication of 5p (dir dup(5) (p13.3{r_arrow}p15.1)), confirmed by fluorescence in situ hybridization (FISH). In addition to a characteristic clinical course, the patient has hyperpigmentation (melanoderma) since birth, normal external genitalia, marked elevation of ACTH, and absent response to an IV ACTH challenge. To the best of our knowledge, this is the first case of congenital hypoplasia of the adrenal gland associated with a chromosome abnormality. Reviews of dup (5p) and of our patient suggest that duplication of 5p13.3-pter has only minor phenotypic effect, while duplication of the relatively small critical segment p11-p13.2 apparently causes far more deleterious changes. The concurrence of CHA and dup(5p) in our patient may indicate the possible gene localization of an autosomal form of CHA to either at or near 5p13.3 or 5p15.1. 25 refs., 3 figs.

    X-linked congenital adrenal hypoplasia (AHC) is a rare developmental disorder of the human adrenal cortex and is caused by deletion or mutation of the DAX-1 gene, a recently discovered member of the nuclear hormone receptor superfamily. Hypogonadotropic hypogonadism is frequently associated with AHC. AHC occurs as part of a contiguous gene syndrome together with glycerol kinase deficiency (GKD) and Duchenne's muscular dystrophy. The present series, collected over the past 2 decades, includes 18 AHC boys from 16 families: 4 with AHC, GKD, and Duchenne's muscular dystrophy; 2 with AHC and GKD; and 12 with AHC (5 young adults with hypogonadotropic hypogonadism). Most of the boys presented with salt wasting and hyperpigmentation during the neonatal period. Plasma steroid determinations performed in the first weeks of life often showed confusing results, probably caused by steroids produced in the neonates' persisting fetocortex. Aldosterone deficiency usually preceded cortisol deficiency, which explains why the patients more often presented with salt-wasting rather than with hypoglycemic symptoms. An ACTH test was often necessary to detect cortisol deficiency in the very young infants. In some patients, serial testing was necessary to establish the correct diagnosis. In 4 boys studied during the first 3 months after birth, we found pubertal LH, FSH, and testosterone plasma levels indicating postnatal transient activation of the hypothalamic-pituitary-gonadal axis as in normal boys. Previous studies have shown that the DAX-1 gene is deleted in the AHC patients with a contiguous gene syndrome and is mutated in nondeletion patients. Most of the point mutations identified in AHC patients were frameshift mutations and stop mutations. In the 15 patients available for molecular analysis of the DAX-1 gene, there were large deletions in 6 patients and point mutations in another 7 patients. All of the point mutations identified in the present study resulted in a nonfunctional

    We report a case of isolated unilateral optic tract hypoplasia, described only twice previously. Bilateral optic disk hypoplasia was seen ophthalmoscopically and visual field studies showed an incongruous right homonymous hemianopia. Magnetic resonance imaging showed bilateral hypoplasia of both optic nerves and the left optic tract. Spectral domain optical coherence tomography mapping correlated well with the visual field studies.

    Hypoplasia adrenal congenita is an extremely uncommon disease of early onset. This condition can be lethal in the absence of treatment. Some forms are due to the congenital adrenal hypoplasia of anencephalic type whose origin is even unknown. Here, we present two cases of congenital adrenal hypoplasia of anencephalic type with pituitary abnormalities. The two male newborns died because adrenal insufficiency in the neonatal period. The adrenal glands were hypoplastic with a histological structure of anencephalic type Immunocytochemical study of the pituitary revealed an absence of the gonadotrophs. No mutation of DAX 1 and SF-1 was found.

    We report on a 2 years and 9 months old Japanese boy with adrenal hypoplasia and mental retardation (MR) (developmental quotient approximately 60) which occurred in the absence of severe adrenal crisis and resultant brain damage. Cytogenetic and molecular studies were performed in this boy and his parents with normal phenotype, showing that the boy had a maternally derived approximately 2 Mb interstitial Xp deletion involving DAX1 (DSS-AHC critical region on the X chromosome, gene 1) for adrenal hypoplasia congenita and disrupting IL1RAPL (interleukin-1 receptor accessory protein-like) for non-specific MR. The results explain the development of MR in this boy in terms of contiguous gene syndrome, and suggest the importance of IL1RAPL analysis in patients with adrenal hypoplasia and MR.

    Congenital adrenal hyperplasia associated with deficiency of steroid 21-hydroxylase is the most common inborn error in adrenal function and the most common cause of adrenal insufficiency in the pediatric age group. As patients now survive into adulthood, adult health-care providers must also be familiar with this condition. Over the past several years, F1000 has published numerous commentaries updating research and practical guidelines for this condition. The purposes of this review are to summarize basic information defining congenital adrenal hyperplasia and to highlight current knowledge and controversies in management. PMID:26339484

    Merke, Deborah P; Bornstein, Stefan R

    Congenital adrenal hyperplasia (CAH) due to deficiency of 21-hydroxylase is a disorder of the adrenal cortex characterised by cortisol deficiency, with or without aldosterone deficiency, and androgen excess. Patients with the most severe form also have abnormalities of the adrenal medulla and epinephrine deficiency. The severe classic form occurs in one in 15,000 births worldwide, and the mild non-classic form is a common cause of hyperandrogenism. Neonatal screening for CAH and gene-specific prenatal diagnosis are now possible. Standard hormone replacement fails to achieve normal growth and development for many children with CAH, and adults can experience iatrogenic Cushing's syndrome, hyperandrogenism, infertility, or the development of the metabolic syndrome. This Seminar reviews the epidemiology, genetics, pathophysiology, diagnosis, and management of CAH, and provides an overview of clinical challenges and future therapies.

    2015-01-01

    Synopsis Adrenal steroidogenesis is a dynamic process, reliant on de novo synthesis from cholesterol, under the stimulation of ACTH and other regulators. The syntheses of mineralocorticoids, glucocorticoids and adrenal androgens occur in separate adrenal cortical zones, each expressing specific enzymes. Congenital adrenal hyperplasia (CAH) encompasses a group of autosomal recessive enzymatic defects in cortisol biosynthesis. 21-hydroxylase (21OHD) deficiency accounts for over 90% of CAH cases and when milder or nonclassic forms are included, 21OHD is one of the most common genetic diseases. This review discusses in detail the epidemiology, genetics, diagnostic, clinical aspects and management of 21OHD. PMID:26038201

  11. Congenital lipoid adrenal hyperplasia

    PubMed Central

    2014-01-01

    Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most fatal form of CAH, as it disrupts adrenal and gonadal steroidogenesis. Most cases of lipoid CAH are caused by recessive mutations in the gene encoding steroidogenic acute regulatory protein (StAR). Affected patients typically present with signs of severe adrenal failure in early infancy and 46,XY genetic males are phenotypic females due to disrupted testicular androgen secretion. The StAR p.Q258X mutation accounts for about 70% of affected alleles in most patients of Japanese and Korean ancestry. However, it is more prevalent (92.3%) in the Korean population. Recently, some patients have been showed that they had late and mild clinical findings. These cases and studies constitute a new entity of 'nonclassic lipoid CAH'. The cholesterol side-chain cleavage enzyme, P450scc (CYP11A1), plays an essential role converting cholesterol to pregnenolone. Although progesterone production from the fetally derived placenta is necessary to maintain a pregnancy to term, some patients with P450scc mutations have recently been reported. P450scc mutations can also cause lipoid CAH and establish a recently recognized human endocrine disorder. PMID:25654062

    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).

  16. On the classification of congenital thumb hypoplasia.

    PubMed

    2014-11-01

    In 1937, Müller introduced the concept of a teratological sequence of thumb hypoplasia with increasing severity from mild deficiency, through severe deficiency, to thumb absence. Blauth subsequently detailed five specific grades. In 1992, Manske and McCarroll altered Blauth's classification such that Grade 3 was sub-divided into Grades 3A and 3B, according to a presence or absence of the proximal metacarpal. Buck-Gramcko added a Grade 3C in which there was only a remnant metacarpal head. This article investigates their publications and those of others to identify 'who said what' and clarify the definitions of grades of thumb hypoplasia. A modification of Blauth's classification is proposed, which retains the integrity of the concept of Müller and the skeletal and soft tissue grading of Blauth, but which also incorporates the disparate anomalies that may present in Grades 2 and 3 hypoplastic thumbs.

    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.

    In congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, affected girls are born with ambiguous genitalia due to increased secretion of androgens in utero by the defective adrenal gland. Even though it is generally accepted that there are differences between male and female brain development, determining factors have been difficult to identify. Girls with CAH have frequently been studied to evaluate the impact of prenatal androgen exposure on psychological, psychosocial, and psychosexual development, and impairments in various areas have been identified. However, there is no comprehensive study available regarding the outcome of this chronic disorder in adult life. We studied the quality of life in women with CAH, with particular emphasis on how they cope with genital malformations, genital operations, and chronic disease as well as lifelong medication. The patients filled out questionnaires covering their physical state, psychological well-being, social relationships, and functional capacity, as well as questionnaires on psychosexual identification and psychosocial integration. The results were evaluated using a computerized statistical program for social studies. Out of a total of 94 patients above 18 years of age, 45 agreed to participate and were compared to 46 healthy, age-matched controls. Age at diagnosis was 2. 31 +/- 1.55 years and 38% suffered from the simple-virilizing, 45% from the salt-wasting, and 17.0% from the late-onset form of CAH. About one-third of patients had Prader stage 3 or 4 genital virilization. While the overall quality of life did not differ significantly, CAH patients were more often single (47.8% vs. 66.7%) and fewer of them had children (22.2% vs. 38.6%) compared to controls. Significant impairments were found in regard to body image and attitudes toward sexuality, but there was no increased homosexual preference. The women were successful in adjusting to illness and receiving social support. It is speculated that

    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 (P<0.05). Comorbid conditions such as obesity, mental retardation, and central precocious puberty were also prominent in this group. In conclusion, this study showed the importance of understanding the clinical symptoms as well as genetic analysis for early diagnosis and management of congenital 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.

    Steroid 21 hydroxylase deficiency is the most common form of congenital adrenal hyperplasia (CAH). The severity of this disorder depends on the extent of impaired enzymatic activity, which is caused by various mutations of the 21 hydroxylase gene. This article reviews adrenal steroidogenesis and the pathophysiology of 21 hydroxylase deficiency. The three forms of CAH are then discussed in terms of clinical presentation, diagnosis and treatment, and genetic basis. Prenatal diagnosis and treatment are also reviewed. The goal of therapy is to correct the deficiency in cortisol secretion and suppress androgen overproduction. Glucocorticoid replacement has been the mainstay of treatment for CAH, but new treatment strategies continue to be developed and studied.

    Congenital hypoplasia of the spinal pedicle is a rare condition. Previously reported cases were treated conservatively or with posterior instrumented fusion. However, the absence or hypoplasia of the lumbar pedicle may increase the difficulty of pedicle screw fixation and fusion. Herein, the authors describe 2 cases of rare adult congenital hypoplasia of the right lumbar pedicles associated with spondylolisthesis. The patients underwent anterior lumbar interbody fusion with a stand-alone cage as well as percutaneous pedicle screw fixation. This method was used to avoid the difficulties associated with pedicle screw fixation and to attain solid fusion. Both patients achieved satisfactory outcomes after a minimum of 2 years of follow-up. This method may be an alternative for patients with congenital hypoplasia of the lumbar spinal pedicle.

    Renal hypoplasia due to a congenitally reduced number of nephrons progresses to chronic kidney disease and may cause renal anemia, given that the kidneys are a major source of erythropoietin in adults. Hypoplastic kidney (HPK) rats have only about 20% of the normal number of nephrons and develop CKD. This study assessed the renal function and hematologic changes in HPK rats from 70 to 210 d of age. HPK rats demonstrated deterioration of renal excretory function, slightly macrocytic erythropenia at all days examined, age-related increases in splenic hemosiderosis accompanied by a tendency toward increased hemolysis, normal plasma erythropoietin levels associated with increased hepatic and decreased renal erythropoietin production, and maintenance of the response for erythropoietin production to hypoxic conditions, with increased interstitial fibrosis at 140 d of age. These results indicate that increases in splenic hemosiderosis and the membrane fragility of RBC might be associated with erythropenia and that hepatic production of erythropoietin might contribute to maintaining the blood Hgb concentration in HPK rats.

    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.

    Capillary blood samples from 42930 infants born in the Italian region of Emilia-Romagna were collected for 17-hydroxyprogesterone radioimmunoassays on days 2, 3, 4, 5, 6, and 7, or between days 7 and 15 of life. A microfilter paper method modified from that of Pang et al.1 was used for this assay. Pathologic values of 17-hydroxyprogesterone were found in 5 infants giving an incidence in this homogeneous Caucasian population of 1:8586. We also investigated 17-hydroxyprogesterone values in relation to the day of sampling and the possible correlation between 17-hydroxyprogesterone values and birthweight and gestational age. We concluded that neonatal screening for congenital adrenal hyperplasia caused by 21-hydroxylase deficiency was possible by this method and that the infants' maturity and the particular day of collection of the samples affect the values but not the validity of the screening.

    Objective. The most common form of congenital adrenal hyperplasia (CAH) is 21-hydroxylase (21-OH) deficiency due to mutation of the CYP21A2 gene. Patients with nonclassical CAH (NC-CAH) are usually asymptomatic at birth and typically present in late childhood, adolescence, or adulthood with symptoms of excessive androgen secretion. Subfertility is relative in NC-CAH, but the incidence of spontaneous miscarriage is higher. Here, we report a previously undiagnosed female who gave birth to a normal male child and is planning to become pregnant again. Case Report. A 32-year-old female was referred to our clinic for obesity. Her medical history revealed that she had had three pregnancies. She was planning to become pregnant again. Her laboratory results revealed that she had NC-CAH. Since her husband is the son of her aunt and she had miscarriages and intrauterin exitus in her history, their genetic analyses were performed. Conclusion. Since most patients with NC-CAH have a severe mutation, these patients may give birth to a child with the classical CAH (C-CAH) if their partner is also carrying a severe mutation. Females with NC-CAH who desire pregnancy must be aware of the risk of having an infant with C-CAH. PMID:26558116

    Congenital thumb hypoplasia is a radial deficiency occurring in the form of sole dysplasia or in combination with additional aberrations. Thumb hypoplasia can be categorised into 5 grades ranging from mild deformity to complete absence of the thumb. Thumb hypoplasia leads to a disturbance of grip function depending on its severity. The choice of treatment is based on the degree of thumb hypoplasia. For hypoplasia greater than grade 3B, restoration of the thumb using pollicization of the index finger is the treatment of choice. For this purpose the index finger is transformed into a thumb and is transposed to the position of the thumb with vessels and nerves being retained. The skeleton has to be shortened, rotated and abducted, followed by reconstruction of the muscles in line with the function of the new thumb. This procedure facilitates a restoration with maximal stability, sensitivity and mobility. In cases of isolated thumb hypoplasia, pollicization of the index finger yields good results persisting into adulthood. If associated aberrations are present, the outcome is less predictable because of the preexistent stiffness of the index finger. Nevertheless, associated aberrations do not represent a contraindication for index finger pollicization.

    X-linked adrenal hypoplasia congenita is caused by the mutation of DAX-1 gene (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1), and can occur as part of a contiguous gene deletion syndrome in association with glycerol kinase (GK) deficiency, Duchenne muscular dystrophy and X-linked interleukin-1 receptor accessory protein-like 1 (IL1RAPL1) gene deficiency. It is usually associated with hypogonadotropic hypogonadism, although in rare cases, it has been reported to occur in normal puberty or even central precocious puberty. This study addresses a case in which central precocious puberty developed in a boy with X-linked adrenal hypoplasia congenita who had complete deletion of the genes DAX-1, GK and IL1RAPL1 (Xp21 contiguous gene deletion syndrome). Initially he was admitted for the management of adrenal crisis at the age of 2 months, and managed with hydrocortisone and florinef. At 45 months of age, his each testicular volumes of 4 mL and a penile length of 5 cm were noted, with pubic hair of Tanner stage 2. His bone age was advanced and a gonadotropin-releasing hormone (GnRH) stimulation test showed a luteinizing hormone peak of 8.26 IU/L, confirming central precocious puberty. He was then treated with a GnRH agonist, as well as steroid replacement therapy. In Korea, this is the first case of central precocious puberty developed in a male patient with X-linked adrenal hypoplasia congenita.

    Leber's congenital amaurosis (LCA), a type of congenital blindness, is clinically and genetically heterogeneous and often associated with systemic anomalies. We report on two sisters who were born to a consanguineous couple and had retinitis pigmentosa-like pigmented retinal lesions, alternating exotropia, bilateral cataracts, and anomalous coarse facies characterized by deformed skull with narrow forehead, low anterior hairline, hypertelorism, short philtrum, thin upper lip, and prominent jaw; cerebellar vermis hypoplasia; dilatation of the fourth ventricle; severe mental retardation; tremor; brisk deep tendon reflexes and abnormal behavior; and skeletal abnormalities such as limited extension of elbow and/ or finger joints and talipes equinovalgus. Skin defect and renal anomalies were seen in only one patient. Our patients are the first familial LCA associated with cerebellar vermis hypoplasia, and the disease involving particular multiple systemic anomalies may represent a distinct clinical entity.

    The adrenal hypoplasia congenita (AHC) and glycerol kinase (GK) loci are telomeric to the Duchenne muscular dystrophy locus in Xp21. The authors developed a pair of yeast artificial chromosome (YAC) contigs spanning at least 1.2 Mb and encompassing the region from the telomeric end of the Duchenne muscular dystrophy (DMD) locus to beyond YHX39 (DXS727), including the genes for AHC and GK. The centromeric contig consists of 13 YACs reaching more than 600 kb from DMD through GK. The telomeric contig group consists of 8 YACs containing more than 600 kb including the markers YHX39 (DXS727) and QST-59 (DXS319). Patient deletion breakpoints in the region of the two YAC contigs define at least eight intervals, and seven deletion breakpoints are contained within these contigs. In addition to the probes developed from YAC ends, they have mapped eight Alu-PCR probes amplified from a radiation-reduced somatic cell hybrid, two anonymous DNA probes, and one Alu-PCR product amplified from a cosmid end, for a total of 26 new markers within this region of 2 Mb or less. One YAC in the centromeric contig contains an insert encompassing the minimum interval for GK deficiency defined by patient deletion breakpoints, and this clone includes all or part of the GK gene. 33 refs., 3 figs., 5 tabs.

    Iris mammillations are dark brown, smooth, mound- or dome-shaped protuberances that are typically found on the anterior iris surface and are presumed to be congenital in origin. This congenital anomaly is usually unilateral and can be hereditary or sporadic. Lisch nodules in neurofibromatosis, tapioca melanoma of the iris, inflammatory iris granulomata and Cogan-Reese syndrome should be considered in the differential diagnosis. In this case report, the authors present a case of a bilateral iris mammillations in two siblings with congenital adrenal hyperplasia (CAH). To our knowledge, this is the first case where bilateral iris mammilations have been found to be associated with a systemic condition. Iris mammillations can be considered as one of the clinical signs in CAH in view of the pathogenesis discussed. Detailed ocular examination in CAH may reveal an increased incidence.

    Three patients with erythroblastic hypoplasia were observed for prolonged periods. In one patient, the phenomenon recurred on three occasions over a 12-year period. In the second, erythroblastic hypoplasia accompanied acute hemolytic anemia of the autoimmune type. The third patient had congenital erythroblastic hypoplasia which was observed for 14 years without remission. From the prolonged periods of observation of these three patients, it is concluded that the phenomenon of erythroblastic hypoplasia may develop abruptly, persist for variable periods of time, remit spontaneously and recur unpredictably. A total of four remissions observed in two patients were believed to be spontaneous and not a result of any of the forms of treatment administered. No remission has occurred in a 14-year-old boy with congenital erythroblastic hypoplasia. A classification of erythroblastic hypoplasia is proposed, based on the clinical circumstances in which the phenomenon has been encountered. ImagesFig. 1Fig. 2Fig. 3Fig. 4 PMID:14155120

    Extracorporeal membrane oxygenation (ECMO) is an effective treatment modality for the newborn with refractory hypoxemia. Oligohydramnios can be associated with congenital renal disease (CRD) and can result in respiratory insufficiency from pulmonary hypoplasia, delayed lung maturation, and persistent pulmonary hypertension of the newborn. In this retrospective study, the authors reviewed the outcome of four children with CRD who required ECMO in the neonatal period. Between October 1987 and December 1995, ECMO was used in four newborns with CRD and pulmonary hypoplasia unresponsive to maximal medical management. The causes of CRD were urinary obstruction (2), renal dysplasia (1), and vesicoureteral reflux (1). Neonatal survivors of ECMO with CRD had regular follow-up with a nephrologist, urologist, and pediatrician. Developmental history, assessment of renal function, and a nutritional evaluation were recorded on each visit. The follow-up period ranged from 6 months to 5 years. All patients with CRD were successfully weaned from ECMO. One child died, at 1 month of age, because of renal failure. The estimated glomerular filtration rates in the three survivors were 20, 24, and 60 mL/min/1.73 m2. Growth and development have been delayed in two patients. Based on the author's experience, ECMO may improve the survival of neonates with pulmonary hypoplasia and CRD. Factors associated with successful long-term outcome include (1) renal disease amenable to surgical correction, (2) aggressive nutritional support, and (3) a reliable social support system.

    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 < 0.001). There was no significant correlation between glucocorticoid dose or serum androgen levels and skeletal endpoints. In conclusion, lean body mass appears to be an important correlate of BMC in patients with CAH. The normal 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 classified as classical CAH and non-classical CAH (NCCAH). In the classical type, the most severe form comprises both salt-wasting and simple virilizing forms. In the non-classical form, diagnosis can be more confusing because the patient may remain asymptomatic or the condition may be associated with signs of androgen excess in the postnatal period or in the later stages of life. This review paper will include information on clinical findings, symptoms, diagnostic approaches, and treatment modules of NCCAH. PMID:27354284

    Congenital adrenal hyperplasia (CAH) is a group of hereditary diseases, which are autosomal recessive. CAH occurs due to defect in one of the cortisol coding genes and often clinically presents itself with signs of androgen overproduction. In this article, we report a case of CAH and Schmid metaphyseal dysplasia. Our literature review indicated that this report is the first attempt on CYP11B1 and Schmid dysplasia in a child. The specific diagnosis of 11-β-hydroxylase deficiency can be determined using high basal levels of deoxycorticosterone and/or 11-deoxycortisol serums. PMID:26722148

    A seven-month-old, entire, male miniature schnauzer dog was referred with acute vomiting, inappetence and depression primarily as a result of a gastric foreign body (pine cones). During investigations, thoracic radiographs revealed increased volume of the right lung lobes, deviated cardiomediastinal structures and elevation of the heart from the sternum. Thoracic computed tomography revealed left cranial lung lobe hypoplasia and extension of the right cranial lung parenchyma across the midline to the left hemithorax. Branches of the right pulmonary vessels and bronchi also crossed the midline and extended to the left caudal lung lobe. These findings suggested that the right and left lungs were fused. In humans this finding is consistent with horseshoe lung, which is an uncommon congenital malformation. To the authors' knowledge, this case represents the first report of such a pulmonary anomaly in a dog.

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is an autosomal recessive disorder caused by mutations in the CYP21A2 gene. Females affected with classical CAH are at risk for genital ambiguity, but can be treated in utero with dexamethasone before 9 gestational weeks to prevent virilization. Early genetic diagnosis is unavailable through current invasive methods of chorionic villus sampling and amniocentesis. New developments in prenatal genetic testing utilize fetal DNA extracted from maternal blood through noninvasive methods, which allow the determination of fetal gender and the diagnosis of CAH at an early gestational age (<9 weeks). Noninvasive prenatal diagnosis allows for the establishment of early and effective management plans in fetuses at risk for CAH and avoids unnecessary prenatal dexamethasone treatment.

    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) 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.

    The psychological development of females with congenital adrenal hyperplasia (CAH) has been previously studied by Money, et al, who found that psychological development of sex identity was consistent with sex assignment despite virilizing adrenal hormones and abnormal external genitalia requiring surgical correction. In this study, using a variety of psychological tests, we assessed the sex-dimorphic behavior, body image, cognitive functioning, and sex-role identity of nine patients ranging in age from 13 to 21, all treated with glucocorticoids and surgical correction. Four of the nine showed moderate virilization despite treatment. Psychological measures included the Wechsler Intelligence Scale for Children-Revised (WISC-R), the Bem Sex-Role Inventory, the Draw-A-Person (DAP) and an interview with patient and family. Results indicate that patients fall within the normal expectable range for this developmental period in visual-spatial and verbal cognitive functioning, in sex-role identity, and in social interpersonal early behaviors. In two areas of functioning these patients demonstrated some variance from the norms, specifically in sexual identity and early activity levels. This suggests that sexual identity and physical activity are most prone to hormonal and psychological impact but that cognition and sex-role identity are not affected. Future studies of this sample will look at personality dimensions such as ego functioning, defense and affect to consider the impact of body image concerns and conflicts.

    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.

    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 latter of which is usually due to autonomous adrenal overproduction. The former can be due to a pituitary corticotroph tumor (usually benign) or ectopic ACTH production from tumors outside the pituitary; both of these tumor types overexpress the proopiomelanocortin gene. The converse of Cushing’s syndrome is the lack of normal cortisol secretion and is usually due to adrenal destruction (primary adrenal insufficiency) or hypopituitarism (secondary adrenal insufficiency). Secondary adrenal insufficiency can also result from a rapid discontinuation of long-term, pharmacological glucocorticoid therapy because of HPA axis suppression and adrenal atrophy. Finally, mutations in the steroidogenic enzymes of the adrenal cortex can lead to congenital adrenal hyperplasia and an increase in precursor steroids, particularly androgens. When present in utero, this can lead to masculinization of a female fetus. An understanding of the dynamics of the HPA axis is necessary to master the diagnosis and differential diagnosis of pituitary-adrenal diseases. Furthermore, understanding the pathophysiology of the HPA axis gives great insight into its normal control. PMID:24715566

    We report on a 7-month-old boy with Micro syndrome who was referred for assessment of mental-motor retardation and reduced vision with cataract. The characteristics of Micro syndrome are mental retardation, microcephaly, congenital cataract, microcornea, microphthalmia, agenesis/hypoplasia of the corpus callosum, and hypogenitalism. The differential diagnosis includes cerebro-oculo-facio-skeletal syndrome (COFS); a syndrome involving cataract, arthrogryposis, microcephaly, and kyphoscoliosis (CAMAK); a syndrome with cataract, microcephaly, failure to thrive, and kyphoscoliosis (CAMFAK); Martsolf syndrome; Neu-Laxova syndrome; Lenz microphthalmia syndrome; and Smith-Lemli-Opitz syndrome. Till date, no renal malformations have been reported in Micro syndrome. Our patient had fusion of the lower poles of the kidneys and his left kidney was ectopic. Ocular findings are the most reliable neonatal diagnostic signs of Micro syndrome. Minör anomalies in Micro syndrome may be subtle and therefore not of significant diagnostic value. Micro syndrome is an autosomal recessive trait. Till date, most reported cases have been in individuals of Muslim origin. In countries with high rates of consanguineous marriage, such as Turkey, it is important that physicians be able to recognize this syndrome. Micro syndrome should be considered in any infant with congenital cataract.

    Lin-Su, Karen; New, Maria I

    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.

    Congenital adrenal agenesis is an extremely rare condition wherein the adrenal glands fail to develop. The absence of adrenal tissue results in the complete absence of hormones produced in the adrenal cortex (cortisol, aldosterone) and medulla (catecholamines), and is not compatible with postnatal life without artificial hormone replacement therapy. To date, 9 cases of adrenal agenesis have been reported, many of which are associated with additional congenital anomalies. Most cases were not detected on antenatal imaging and were detected incidentally at postmortem examination. We present a case of adrenal agenesis, detected incidentally at postmortem examination after termination of pregnancy for suspected fetal hydrops, and review the heterogeneous phenotype of this condition with associated abnormalities and molecular genetics. This case reinforces the role of the perinatal autopsy to investigate cause of perinatal mortality, allowing correlation of pathology with antenatal imaging findings and clinical details.

    Purpose: Congenital portosystemic shunts (CPSS) with portal venous hypoplasia cause hyperammonemia. Acute shunt closure results in portal hypertension. A transcatheter method of staged shunt reduction to afford growth of portal vessels followed by shunt closure is reported. Methods: Pressure measurements and angiography in the CPSS or superior mesenteric artery (SMA) during temporary occlusion of the shunt were performed. If vessels were diminutive and the pressure was above 18 mmHg, a staged approach was performed, which included implantation of a tailored reducing stent to reduce shunt diameter by {approx}50 %. Recatheterization was performed approximately 3 months later. If the portal pressure was below 18 mmHg and vessels had developed, the shunt was closed with a device. Results: Six patients (5 boys, 1 girl) with a median age of 3.3 (range 0.5-13) years had CPSS portal venous hypoplasia and hyperammonemia. Five patients underwent staged closure. One patient tolerated acute closure. One patient required surgical shunt banding because a reducing stent could not be positioned. At median follow-up of 3.8 (range 2.2-8.4) years, a total of 21 procedures (20 transcatheter, 1 surgical) were performed. In all patients, the shunt was closed with a significant reduction in portal pressure (27.7 {+-} 11.3 to 10.8 {+-} 1.8 mmHg; p = 0.016), significant growth of the portal vessels (0.8 {+-} 0.5 to 4.0 {+-} 2.4 mm; p = 0.037), and normalization of ammonia levels (202.1 {+-} 53.6 to 65.7 {+-} 9.6 {mu}mol/L; p = 0.002) with no complications. Conclusion: Staged CPSS closure is effective in causing portal vessel growth and treating hyperammonemia.

    Purpose: Women with congenital adrenal hyperplasia (CAH) may develop a virilized voice due to late diagnosis or suboptimal suppression of adrenal androgens. Changes in the vocal folds due to virilization have not been studied in vivo. The purpose was to investigate if the thyroarytenoid (TA) muscle is affected by virilization and correlate…

  1. Clinical and molecular review of atypical congenital adrenal hyperplasia

    PubMed Central

    2015-01-01

    Congenital adrenal hyperplasia (CAH) is one of the most common inherited metabolic disorders. It comprises a group of autosomal recessive disorders caused by the mutations in the genes encoding for steroidogenic enzymes that involved cortisol synthesis. More than 90% of cases are caused by a defect in the enzyme 21-hydroxylase. Four other enzyme deficiencies (cholesterol side-chain cleavage, 17α-hydroxylase [P450c17], 11β-hydroxylase [P450c11β], 3β-hydroxysteroid dehydrogenase) in the steroid biosynthesis pathway, along with one cholesterol transport protein defect (steroidogenic acute regulatory protein), and one electrontransfer protein (P450 oxidoreductase) account for the remaining cases. The clinical symptoms of the different forms of CAH result from the particular hormones that are deficient and those that are produced in excess. A characteristic feature of CAH is genital ambiguity or disordered sex development, and most variants are associated with glucocorticoid deficiency. However, in the rare forms of CAH other than 21-hydroxylase deficiency so-called "atypical CAH", the clinical and hormonal phenotypes can be more complicated, and are not well recognized. This review will focus on the atypical forms of CAH, including the genetic analyses, and phenotypic correlates. PMID:25883920

    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.

    Psychological outcomes in persons with congenital adrenal hyperplasia (CAH) have received substantial attention. The objectives of this paper were to (1) catalog psychological endpoints assessed in CAH outcome studies and (2) classify the conceptual/theoretical model shaping the research design and interpretation of CAH-related psychological effects. A total of 98 original research studies, published between 1955 and 2009, were categorized based on psychological endpoints examined as well as the research design and conceptual model guiding analysis and interpretation of data. The majority of studies (68%) investigated endpoints related to psychosexual differentiation. The preponderance of studies (76%) examined a direct relationship (i.e., inferring causality) between prenatal androgen exposure and psychological outcomes. Findings are discussed in relation to the observed imbalance between theoretical interest in the role of prenatal androgens in shaping psychosexual differentiation and a broader conceptual model that examines the role of other potential factors in mediating or moderating the influence of CAH pathophysiology on psychological outcomes in both affected females and males. The latter approach offers to identify factors amenable to clinical intervention that enhance both health and quality of life outcomes in CAH as well as other disorders of sex development.

    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 could provide a promising model for the study of the effects of hormones on cognition. The aim of this study was to assess sexual dimorphic abilities related to oral language, spatial abilities, and verbal fluency and to determine the existence of learning disabilities in 11 congenital girls with adrenal hyperplasia compared with 11 healthy girls. Both groups underwent a neuropsychological evaluation using the Child Neuropsychological Assessment battery for Spanish-speaking children. Results showed that the congenital adrenal hyperplasia group had a significantly lower performance than the control group in the repetition and expression domains, right-left comprehension task, and verbal semantic fluency task. A higher incidence of learning disabilities (predominantly reading related) in the patient group compared with their controls was also evident. Thus, the presence of weak verbal areas along with a high incidence of learning disabilities related primarily, though not exclusively, to reading was documented in these girls.

    Cerebellar hypoplasias are cerebellar malformations with small but completely formed cerebellum. They can be divided in focal and in diffuse or generalized. It is sometimes difficult to make distinction between cerebellar atrophy (progressive condition) and hipoplasia (not progressive condition). Focal hypoplasias are restricted to one cerebellar hemisphere or to the vermis. Diffuse hypoplasias refer to both cerebellar hemispheres and vermis. If there is associated IVth ventricle enlargement, hypoplasias occur in the context of Dandy-Walker complex, a continuum of posterior fossa cystic anomalies. A revision of cerebellar hypoplasias and associated pathology is done, illustrated with 22 cases tha include focal and diffuse cerebellar hypoplasias, Dandy-Walker malformations and its variant, persistent Blake's pouch cyst, megacisterna magna, PEHO síndrome (progressive encephalopathy with oedema, hipsarrhythmia and optic atrophy), Joubert syndrome, congenital disorder of glycosylation type Ia, pontocerebellar hipoplasias Barth type I and II, diffuse subcortical heterotopia. The imaging finding of structural cerebellar anomalies frequently leads to diagnostic incertainty as the anomalies are mostly unspecific, implying an extenuating analytical and genetic workup. Their knowledge and classification may be useful to decide the patient adjusted laboratorial workup.

    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

    In this paper, we report a case of a 14-year-old girl with congenital aplasia of the flexor pollicis longus tendon who had no other associated anomalies of thumb hypoplasia and no trauma history. Flexor pollicis longus tendon anomalies are rare; several types of this congenital anomaly have been reported in the literature. The diagnosis should be considered if a patient is unable to flex the interphalangeal joint of the thumb. A hypoplastic thumb or an absent interphalangeal joint crease may be a diagnostic feature in such cases. Besides physical examination, we also used direct radiography and magnetic resonance imaging to diagnose this rare congenital anomaly in our patient.

    Assays of serum 17-hydroxyprogesterone concentration may be relied upon to establish a diagnosis of congenital adrenal hyperplasia within a few hours of birth. In a male infant the concentration of 17-hydroxyprogesterone was increased in cord serum and remained elevated until glucocorticoid therapy was started on the 5th day of life. Plasma renin activity was increased only slightly in the first few days, but a striking increase on day 5, along with a gradual increase in the serum potassium concentration, confirmed that the infant had the salt-losing form of congenital adrenal hyperplasia. It was not possible to demonstrate an increased concentration of 17-hydroxyprogesterone, in amniotic fluid obtained at 30 weeks' gestation, presumably because of interference in this assay by cross-reacting steroids. Studies of the mother's serum concentration of 17-hydroxyprogesterone and cortisol during delivery did not disclose any deviation from normal. PMID:890632

    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.

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a common autosomal recessive disorder. Ornithine transcarbamylase (OTC) deficiency is the most common urea cycle disorder and demonstrates X-linked inheritance. In female OTC deficiency, phenotypes are variable according to X-inactivation patterns. These disorders develop separately, and their co-morbidity is extremely rare. We report one girl with CAH showing recurrent hyperammonemia and hepatitis after 2 years-of-age due to additional OTC deficiency.

    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 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.

    Fertility in women with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) appears to be reduced, especially in women with the classic salt-wasting type. Several factors have been suggested to contribute to this subfertility such as androgen excess, adrenal progesterone hypersecretion, consequences of genital reconstructive surgery, secondary polycystic ovaries syndrome, and psychosexual factors. In contrast to this subfertility, pregnancies are commonly normal and uneventful. Adequate glucocorticoid therapy and improvement of surgical and psychological management could contribute to optimize fertility in CAH female patients, even among women with the classic variant. This review provides current information regarding the reproductive outcomes of women with CAH due to 21-OHD and the fertility and pregnancy issues in this population. PMID:24083158

    The steroidogenic acute regulatory (StAR) protein is essential for all hormone-stimulated steroid biosynthesis. Accordingly, its absence gives rise to the most severe form of congenital adrenal hyperplasia (CAH), lipoid CAH. This life-threatening condition typically manifests itself in the perinatal period. Partial loss-of-function StAR mutations incompletely manifest the condition later in life and are a cause of familial glucocorticoid deficiency type 3. Here, we discuss StAR, its expression pattern and the clinical consequences of the loss of its activity.

    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.

    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 (<6.5 nmol/L). CT abdomen was performed as the patient complained of rapid-onset increasing abdominal girth and revealed bilateral large adrenal myelolipomata. MRI brain revealed a large meningioma involving the right 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

    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.

    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.

    Children with classic congenital adrenal hyperplasia (CAH) have multiple endocrine imbalances, including prenatal glucocorticoid and adrenomedullary deficiency and androgen excess, with possible postnatal iatrogenic glucocorticoid excess, hyperandrogenism, and adrenomedullary hypofunction. Prenatal masculinization of the brain has been suggested in girls with classic CAH. Hormones of the hypothalamic-pituitary-adrenal axis and sex hormones interact with extrahypothalamic regulatory centers of the brain, including the amygdala and hippocampus. The amygdala is important in the processing of emotion and generation of fear, whereas the hippocampus plays an important role in memory. Chronic hypercortisolemia has been shown to be associated with hippocampal damage, while glucocorticoids and corticotropin-releasing factor play a major role in the regulation of amygdala function. We performed magnetic resonance imaging of the brain on 27 children with classic CAH and 47 sex- and age-matched controls. Volumes of the cerebrum, ventricles, temporal lobe, amygdala, and hippocampus were quantified. Females with CAH did not have brains with male-specific characteristics. In contrast, a significant decrease in amygdala volume was observed in both males and females with CAH (males, P = 0.01; females, P = 0.002). Iatrogenic effects on the hippocampus due to glucocorticoid therapy were not observed in children with CAH. These results suggest that prenatal glucocorticoid deficiency with resulting alterations in hypothalamic-pituitary-adrenal axis regulation, sex steroid excess, or some combination of these preferentially affect the growth and development of the amygdala, a structure with major functional implications that warrant further exploration.

    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.

    Congenital lipoid adrenal hyperplasia (CLAH) is a rare autosomal recessive disorder caused by defective synthesis of all steroids. This disorder is characterized by 46,XY sex reversal, skin hyperpigmentation, early-onset adrenal crisis and enlarged adrenal with fatty accumulation. CLAH is caused by mutations in the STAR gene. The clinical features and STAR gene mutation spectrum of a large cohort of Chinese patients with CLAH were not reported previously. We performed clinical retrospective review and genetic analysis of the STAR gene in ten unrelated Chinese phenotypic female patients who were clinically diagnosed with CLAH and followed up in our hospital from 2006 to 2015. All ten patients, including two 46,XY females and eight 46,XX females, presented skin hyperpigmentation and early salt-wasting episode, and showed normal growth and development after steroid replacement treatment. Totally 20 mutant alleles containing 11 different STAR gene mutations were identified in these ten patients, including five novel variants (two missense and three null variants), all predicted to be pathogenic in bioinformatics analysis, and six mutations described in previous literature. Among these 11 mutations, a reported mutation c.772C>T and a novel variant c.707_708delinsCTT were most frequent, accounting for 35% and 15% of the total mutant alleles, respectively. This is the first report of a large Chinese cohort with CLAH, presenting the mutation spectrum of the STAR gene and two possible founder mutations in the Chinese population, which may contribute to better genetic counseling and prenatal diagnosis.

  10. Management issues of congenital adrenal hyperplasia during the transition from pediatric to adult care

    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

    Abstract 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. PMID:26107677

    We described a case of congenital atresia of the anterior nares with a minute opening on the right side and underdevelopment of the nasal cavities. The hard palate was flat and the soft palate was normally mobile. Right anophthalmia and microphthalmia of the left eye with iris coloboma were also noted. In order to provide a nasal airway and to enable the newborn to suck and breathe simultaneously the patient was operated on at four days of age. By means of transpalatal approach a nasal cavity was drilled out of solid bone and connected with the small anterior duct. Trough the new created air duct a nasopharyngeal tube was introduced. In spite of that the external nasal orifice was enlarged later, there was an inclination the orifice to collapse due to lack of nostril cartilages, therefore a nasopharyngeal tube still is used. The physical and intellectual development of the now 11-month old infant is normal. Final reconstruction of the external nose will take place later.

    Congenital adrenal hyperplasia describes a group of inherited autosomal recessive disorders characterized by an enzymatic defect in cortisol biosynthesis, compensatory increases in corticotropin secretion, and adrenocortical hyperplasia. 21-Hydroxylase deficiency is responsible for more than 95% of cases and is one of the most common known autosomal recessive disorders. The classic or severe type presents in the newborn period or early childhood with virilization and adrenal insufficiency, with or without salt loss; the mild or nonclassic form presents in late childhood or early adulthood with mild hyperandrogenism and is an important cause of masculinization and infertility in women. This wide range of phenotypic expression is mostly explained by genetic variation, although genotype-phenotype discrepancies have been described. Reproductive, metabolic, and other comorbid conditions, including risk for tumors, are currently under investigation in both forms of the disease. A high proportion of patients with adrenal incidentalomas may be homozygous or heterozygous for 21-hydroxylase deficiency. Women with congenital adrenal hyperplasia often develop the polycystic ovary syndrome. Ectopic adrenal rest tissue is often found in the testes of men with congenital adrenal hyperplasia; characteristic clinical and radiologic findings help differentiate this tissue from other tumors. Levels of corticotropin-releasing hormone are elevated in patients with depression and anxiety and are expected to be elevated in patients with congenital adrenal hyperplasia; it is unknown whether patients with 21-hydroxylase deficiency have an increased incidence of these psychiatric disorders. Abnormalities in both the structure and function of the adrenal medulla have been shown in patients with classic congenital adrenal hyperplasia, and the degree of adrenomedullary impairment may be a biomarker of disease severity. The 21-hydroxylase-deficient mouse has provided a useful model with which

    A male presented at age 2.2 years with a 6-week history of intermittent vomiting and hyperpigmentation. Investigations showed salt wasting with hyperkalaemia, a grossly impaired cortisol response to ACTH stimulation, elevated renin and ACTH. Family history revealed that two maternal uncles had died soon after birth. A third uncle failed to thrive during infancy but improved with a course of cortisone, then being untreated until further investigation revealed adrenal insufficiency. A fourth uncle died aged 10 days, with urinary salt loss and hypoplastic adrenal glands at postmortem. Molecular studies on the proband, his mother, maternal grandmother, and surviving uncle showed a novel C to G substitution at nucleotide position 794 (missense mutation T265R) in the DAX1 (NR0B1) gene. The proband has responded well to steroid replacement but has proved sensitive to 9α-fludrocortisone treatment, developing hypertension on a dose of 133 μg/m2/day. At 8.8 years he was noted to have testicular volumes of 4 ml, despite no other evidence of secondary sexual development and prepubertal gonadotrophin levels. Novel features of this family include a novel DAX1 mutation, marked variability in age of presentation, hypertension on ‘standard’ doses of 9α-fludrocortisone and mild testicular enlargement.

    Following the introduction of life-saving glucocorticoid replacement 60 years ago, congenital adrenal hyperplasia (CAH) has evolved from being perceived as a paediatric disorder to being recognized as a lifelong, chronic condition affecting patients of all age groups. Increasing evidence suggests that patients with CAH have an increased risk to develop health problems during adult life, with signs and symptoms of forerunner conditions of adult disease already emerging during the time of paediatric care. Transition of paediatric CAH patients to medical care in the adult setting is an important step to ensure optimal lifelong treatment, aiming to achieve good health and normal life expectancy and quality of life. Thus, primary and secondary prevention of health problems has to become a task of increasing importance for those involved in the care of CAH patients throughout their life.

    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).

    Personality traits and platelet monoamine oxidase (MAO) activity were studied in 22 women, 17-34 years old, with prenatal virilization due to congenital adrenal hyperplasia (CAH) (21-hydroxylase deficiency) and 22 healthy controls. The CAH group differed significantly on two of the eight scales of the Karolinska Scales of Personality (KSP), which have earlier shown significant gender differences. Both differences were in the masculine direction, with a high, male level, score for Detachment and a lower score for Indirect Aggression. The Detachment scale reflects distance in social relations, and has earlier been shown to be strongly gender differentiating. There was no significant difference in platelet MAO activity between the CAH group and the controls. Although an influence of psychosocial factors cannot be excluded, the results suggest a possible association between prenatal androgen exposure and the high Detachment score for the CAH group. Gender differences in empathy, affiliation motivation, intimacy and maternal behavior may be relevant parallels.

    Testosterone promotes male-typical neural and behavioral development in non-human mammals. There is growing evidence that testosterone exerts similar influences on human development, although the range of behaviors affected is not completely known. This study examined the hypothesis that autistic traits are increased following prenatal exposure to abnormally high levels of testosterone caused by congenital adrenal hyperplasia (CAH). Sixty individuals with CAH (34 female, 26 male) and 49 unaffected relatives (24 female, 25 male) completed the Autism Spectrum Quotient (AQ). Females with CAH scored significantly higher than unaffected females on total AQ score, largely due to enhanced scores on subscales measuring social skills and imagination. These results suggest that prenatal exposure to high levels of testosterone influences some autistic traits and that hormonal factors may be involved in vulnerability to autism.

    Salt appetite was investigated in 14 patients with congenital adrenal hyperplasia of the salt-wasting form (SW group), 12 patients with the simple virilized form who are not salt losing, and 18 healthy siblings. Salt appetite was evaluated by questionnaire, preference tests, and dietary analyses. The findings showed that SW who were not therapeutically normalized showed increased salt appetite but no change in sweet preference. Their salt appetite correlated with symptoms of salt wasting, namely, plasma renin activity, plasma K(+), and urine Na(+) and (inversely) with blood pressure. Sensitivity to the taste of NaCl was not altered. Factor analyses of a larger group confirmed the distinction between salt appetite and sweet preference, but intake of dietary Na(+) and sweet carbohydrates and intake of salty and sweet snacks did not reflect distinct salt or sweet preferences. We confirm that putative perinatal dehydration, due to maternal nausea and vomiting during pregnancy, childhood vomiting, and diarrhea with occasional saline infusion, was related to increased salt appetite in adolescence. The findings suggest that salt appetite in humans is determined by interdependent, innate, physiological, and acquired attributes. Salt appetite in SW patients is an adaptive response mediated by the renin-angiotensin system, an innate predisposition to acquire salt preference (in anticipation of both sodium loss and its consequence), and imprinting by perinatal hyponatremic occurrences. Our findings contribute to understanding human salt intake, provide insight into the motivation for salt in patients with congenital adrenal hyperplasia 21-OH deficiency, and may point the way to improvements in therapeutic compliance in these patients.

    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. PMID:22837923

    There is no clear consensus among state newborn screening programs on whether routine second screening of newborns identifies clinically relevant cases of congenital adrenal hyperplasia. This retrospective study evaluated laboratory practices, along with biochemical and medical characteristics of congenital adrenal hyperplasia (CAH) cases (1) detected on the first newborn screen in one-screen compared to two-screen states, and (2) detected on the first versus the second screen in the two-screen states, to determine the effectiveness of a second screen. A total of 374 confirmed cases of CAH from 2 one-screen states and 5 two-screen states were included in this study. Demographic data and diagnostic information on each reported case were collected and analyzed. Additionally, laboratory data, including screening methodologies and algorithms, were evaluated. The one-screen states reported 99 cases of CAH out of 1,740,586 (1 in 17,500) newborns screened: 88 (89%) identified on first screen and 5 (5%) identified on targeted second screen. The two-screen states reported 275 cases of CAH out of 2,629,627 (1 in 9,500) newborns screened: 165 (60%) identified on first screen and 99 (36%) identified on second screen. Using a multivariate model, the only significant predictor of whether a case was identified on the first or second screen in the two-screen states was the type of CAH. Compared with classical salt-wasting CAH, classical simple virilizing and non-classical CAH cases were less likely to be detected on the first versus the second screen. The routine second newborn screen is important for identifying children with CAH, particularly simple virilizing and non-classical forms, which might otherwise not be captured through a single screen.

    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 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.

    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.

    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.

    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.

    The ratio of the length of the second digit (2D) to the length of the fourth digit (4D) is greater in women than in men. Since androgens are involved in most somatic sex differences and since the sexual dimorphism in 2D:4D is stable from 2 years of age in humans, it was hypothesized that finger length pattern development might be affected by early androgen exposure. Human females with congenital adrenal hyperplasia (CAH) are exposed prenatally to higher than normal levels of adrenal androgens, providing an opportunity to test the effects of early androgen exposure on digit ratios. The 2D:4D was calculated for females with CAH, females without CAH, males with CAH, and males without CAH. Females with CAH had a significantly smaller 2D:4D on the right hand than did females without CAH. Males with CAH had a significantly smaller 2D:4D on the left hand than did males without CAH. A subset of six males with CAH had a significantly smaller 2D:4D on both hands compared with their male relatives without CAH. These results are consistent with the idea that prenatal androgen exposure reduces the 2D:4D and plays a role in the establishment of the sex difference in human finger length patterns. Finger lengths may therefore offer a retrospective marker of perinatal androgen exposure in humans.

    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.

    Congenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase deficiency is a common autosomal recessive disorder due to mutations in the CYP21A2 gene. Since genetic counselors play a crucial role in educating families about inherited disorders, they need to have thorough knowledge regarding the pathophysiology of CAH especially the effects on the fetus, the complex genetics of this disorder, and the controversies surrounding experimental prenatal dexamethasone treatment. Affected female fetuses may have varying degree of virilization of the external genitalia. Starting in the 1980's, supraphysiologic glucocorticoid treatment was used to decrease the virilization of the external genitalia of affected female fetuses. However, recent clinical observations, animal studies and greater awareness of the details of human fetal adrenal physiology raise concerns regarding the safety of this prenatal treatment. We review the pathophysiology of CAH, the safety and ethical considerations of prenatal dexamethasone treatment and the views of multiple medical societies that conclude that this experimental therapy should only be done in prospective trials approved by ethical review boards.

    2017-03-15

    Pulmonary hypoplasia, although rare, is associated with significant neonatal morbidity and mortality. Conditions associated with pulmonary hypoplasia include those which limit normal thoracic capacity or movement, including skeletal dysplasias and abdominal wall defects; those with mass effect, including congenital diaphragmatic hernia and pleural effusions; and those with decreased amniotic fluid, including preterm, premature rupture of membranes, and genitourinary anomalies. The ability to predict severe pulmonary hypoplasia prenatally aids in family counseling, as well as obstetric and neonatal management. The objective of this review is to outline the imaging techniques that are widely used prenatally to assess pulmonary hypoplasia and to discuss the limitations of these methods.

    Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is an autosomal recessive disorder caused by mutations in the CYP21A2 gene. Cortisol and aldosterone synthesis are impaired in the classic forms (adrenal insufficiency and salt-wasting crisis). Females affected are virilised at birth, and are at risk for genital ambiguity. In this article we give recommendations for an early as possible diagnosis and an appropriate and individualised treatment. A patient and family genetic study is essential for the diagnosis of the patient, and allows genetic counselling, as well as a prenatal diagnosis and treatment for future pregnancy.

    Background Boys carrying mutations in the NR0B1 gene develop adrenal hypoplasia congenita (AHC) and impaired sexual development due to the combination of hypogonadotropic hypogonadism (HH) and primary defects in spermatogenesis. Methods We analysed the evolution of hypothalamic-pituitary-testicular function of 8 boys with AHC due to NR0B1 mutations. Our objective was to characterize and monitor the progressive deterioration of this function. Results The first symptoms appeared in the neonatal period (n = 5) or between 6 months and 8.7 years (n = 3). Basal plasma adrenocorticotrophic hormone (ACTH) concentrations increased in all boys, whilst cortisol levels decreased in one case. The natremia was equal or below 134 mmol/L and kaliemia was over 5 mmol/L. All had increased plasma renin. In 3 of 4 patients diagnosed in the neonatal period and evaluated during the first year, the basal plasma gonadotropins concentrations, and their response to gonadotropin releasing hormone (GnRH) test (n = 2), and those of testosterone were normal. The plasma inhibin B levels were normal in the first year of life. With the exception of two cases these concentrations decreased to below the normal for age. Anti-Müllerian hormone concentrations were normal for age in all except one case, which had low concentrations before the initiation of testosterone treatment. In 3 of the 8 cases the gene was deleted and the remaining 5 cases carried frameshift mutations that are predicted to introduce a downstream nonsense mutation resulting in a truncated protein. Conclusions The decreases in testosterone and inhibin B levels indicated a progressive loss of testicular function in boys carrying NR0B1 mutations. These non-invasive examinations can help to estimate the age of the testicular degradation and cryopreservation of semen may be considered in these cases as investigational procedure with the aim of restoring fertility.

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

    PubMed

    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

    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.

    Late onset congenital adrenal hyperplasia (LO CAH) can be seen in association with polycystic ovary syndrome (PCOS) or idiopathic hirsutism (IH). The study aimed to find out the prevalence of LO CAH in Central Anatolia among hirsute women. Sixty-three patients with hirsutism were evaluated to determine the frequency of LO CAH by comparing them with their age and body mass index matched 28 healthy controls. Of those 63 hirsute women, 43 were diagnosed as PCOS, and 20 were diagnosed as IH. Following basal hormonal evaluation, all subjects underwent ACTH stimulation test and ACTH stimulated 17-hydroxyprogesterone (17-OH P), 11-desoxycortisol (11-DOC), cortisol (F), and dehydroepiandrosterone sulfate (DHEA-S) levels were determined in all subjects. ACTH stimulated 17-OH P, 11-DOC, and DHEA-S levels did not differ between groups. However, stimulated F levels were found to be higher in hirsute women (p<0.001). Six out of 63 (9.52%) patients with hirsutism met the criterion for 21 hydroxylase deficiency. We found no subject presumed to have 11-beta hydroxylase deficiency, but one subject in control group (3.57%) and two patients among PCOS subjects (4.65%) had exaggerated DHEA-S response which was suggestive of mild 3-beta hydroxysteroid dehydrogenase deficiency. In conclusion, the most frequent form of LO CAH seems to be due to 21 OH deficiency among women with PCOS and IH in Central Anatolia. Mild 3-beta HSD deficiency may also be an underlying cause for hirsutism and it may be seen without any clinical presentation. Adrenal hyperactivity is likely to be the main reason of hyperandrogenemia in women with hirsutism.

    This study tested the hypothesis that prenatal androgen levels influence hand preferences and language lateralization, two manifestations of neural asymmetry. Participants were individuals with congenital adrenal hyperplasia (CAH, a genetic disorder that results in excess adrenal androgen production beginning prenatally) (40 females; 29 males) and their unaffected relatives (29 females; 30 males) who ranged in age from 12-45 years. The Edinburgh-Crovitz Inventory and the performance of five simple tasks (the Handedness Activities Test) were the measures of hand preferences, and a dichotic listening task composed of consonant-vowel nonsense syllables was the measure of language lateralization. No sex differences were observed among relative controls in hand preferences or language lateralization. Male participants with CAH were less consistently right-handed for writing than unaffected male relatives, when those who had been forced to switch writing hands from left to right were considered with left-handers as being not consistently right-handed. There were no other significant differences between individuals with CAH and unaffected relatives. These results do not support the hypothesis that prenatal androgens influence language lateralization, nor do they support the Geschwind-Behan-Galaburda model that posits a key role for testosterone in the development of cognitive problems in males, secondary to changes in hemispheric development and cognitive lateralization. Hormonal influences on handedness, although not always consistent, may be more likely. However, given that sex differences in both language lateralization and handedness are small, it is possible that limited sample size precludes the detection of consistent group differences.

    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.

    A retrospective study was performed on all patients with congenital adrenal hyperplasia (CAH) who were followed up at the King Hussein Medical Center (KHMC), Amman, Jordan, during the period from January 1996 to June 2006. The aim was to evaluate the clinical features, special problems, and corrective interventions for these patients. The records of 73 children (39 were genetic females and 34 were genetic males) with CAH were reviewed in the study. The age of the patients at last follow-up was between five months and 18 years. Diagnostic criteria for CAH were typical clinical features of the illness (salt loss, dehydration, virilization, macrogenitosomia, ambiguous genitalia, and accelerated growth) and typical hormonal abnormalities (decreased serum cortisol and elevated serum 17-hydroxyprogesterone). There were 62 patients with classical presentation; among them, salt-wasting (SW) form was seen in 41 patients (66%). There were 5 patients with the nonclassic form, while 6 others had cryptic presentation. Seven patients (9%) had hypertension, mostly due to salt-retaining CAH. Among the 39 females with CAH, 27 had developed mental anomalies of the external genitalia; 20 of them underwent surgical interventions of their external genitalia. Fourteen genetically female patients were wrongly diagnosed as 'male sex' at birth due to severe virilization. Seven of them were reassigned 'female sex' socially, legally, and surgically; the parents of one of them (a four-year-old girl) wanted the surgical intervention postponed for two to three years. Hysterectomy and gonadectomy were carried out for 6 of the other 7 patients who chose to keep the male gender. Our study indicates that newborns with developmental anomalies of the external genitalia should be diagnosed as early as possible so that medical, psychological, and social complications are minimized. A neonatal screening program for such a disorder can identify infants at risk for the development of life

    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), 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.

    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.

    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.

    2016-01-01

    Congenital adrenal hyperplasia (CAH) is a rare autosomal recessive disorder caused by mutations in the cytochrome P450 family 17 subfamily A member 1 (CYP17A1) gene located on chromosome 10q24.3, which leads to a deficiency in 17α-hydroxylase/17,20-lyase. The disorder is characterized by low blood levels of estrogens, androgens and cortisol, which leads to a compensatory increase in adrenocorticotropic hormone levels that stimulate the production of mineralocorticoid precursors. This subsequently leads to hypertension, hypokalemia, primary amenorrhea and sexual infantilism. Over 90 distinct genetic lesions have been identified in patients with this disorder. The prevalence of common mutation of CYP17A1 gene differs among ethnic groups. Treatment of this disorder involves replacement of glucocorticoids and sex steroids. Estrogen alone is prescribed for patients who are biologically male with 17α-hydroxylase deficiencies that identify as female. However, genetically female patients may receive estrogen and progesterone supplementation. In the present study, a 17-year-old female with 17α-hydroxylase/17,20-lyase deficiency that presented with primary amenorrhea and sexual infantilism and no hypertension, was examined. The karyotype of the patient was 46, XX, and genetic analysis revealed the presence of a compound heterozygous mutation in exons 6 and 8, leading to the complete absence of 17α-hydroxylase/17,20-lyase activity. The patient was treated with prednisolone and ethinyl estradiol. In addition, a summary of the recent literature regarding CAH is presented. PMID:27959413

    Major questions remain about the exact role of hormones in cognition. Furthermore, the extent to which early perturbation in steroid function affects human brain development continues to be a wide open area of research. Congenital adrenal hyperplasia (CAH), a genetic disorder of steroid dysfunction characterized in part by in utero over-production of testosterone, was used as a natural model for addressing this question. Here, CAH (n=54, mean age=17.53, 31 female) patients were compared to healthy age- and sex-matched individuals (n=55, mean age=19.02, 22 female) on a virtual equivalent of the Morris Water Maze task [Morris, R., 1984. Developments of a water-maze procedure for studying spatial learning in the rat. J. Neurosci. Methods 11, 47-60], an established measure of sex differences in spatial cognition in rodents. Findings revealed that females with CAH with the most severe form of the disease and expected highest level of in utero exposure to androgens were found to perform similarly to both healthy males and CAH males, whereas strong sex differences were apparent in milder forms of the disorder and in controls. Moreover, advanced bone age, an indicator of long-term childhood exposure to testosterone was correlated with improved performance. The results indicate that individuals exposed to both excess androgens prenatally and prolonged exposure during childhood may manifest long-lasting changes in cognitive function. Such finding suggests a pivotal role of hormonal function on brain development in humans, mirroring results from the animal literature.

    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.

    21-hydroxylase deficiency (P450 CYP21) accounts for 90% of cases of congenital adrenal hyperplasia (CAH), which is associated with abnormally low cortisol and high production of androgen precursors and is the most common cause of ambiguous genitalia. Increased androgen causes in utero virilization of the fetus, consisting of clitoral enlargement, an urogenital sinus, and labioscrotal enlargement and fusion. This is the first case in an experience covering more than 30 years, of a 46,XX patient raised as a boy. The authors report a case of a Pakistani patient born of a consanguineous union, who came to medical attention at age 3 because of severe genital ambiguity; genetic analyses showed that the child was a compound heterozygote for CAH. The surgical management of this patient consisted of (1) staged hypospadias repairs preceded by testosterone therapy, (2) creation of a bladder graft neourethra, (3) removal of müllerian structures, (4) correction of bifid prepenile scrotum, and (5) insertion of testicular prostheses. The commitment to raise a 46,XX child as a boy is a very rare event. With a series of staged complex surgical procedures and careful steroid replacement, normal secondary sexual characteristics can be achieved in these children.

    Individuals with classic congenital adrenal hyperplasia (CAH) experience impaired glucocorticoid production and are treated postnatally with glucocorticoids. Prior research with animals and other human populations indicates that glucocorticoids can influence memory, particularly working memory. We tested the hypothesis that children with CAH would show reduced working memory. Children in the United Kingdom, aged 7-11 years, with classical CAH (31 girls, 26 boys) were compared to their unaffected relatives (30 girls, 20 boys) on a test of working memory, the Digit Span test. Vocabulary was also assessed to measure verbal intelligence for control purposes. Children with CAH showed reduced working memory performance compared to controls, on both components of the Digit Span test: p = .008 for Digit Span Forward, and p = .027 for Digit Span Backward, and on a composite score, p = .004. These differences were of moderate size (d = .53 to .70). Similar differences were also seen in a subset of 23 matched pairs of children with CAH and their relatives (d = .78 to .92). There were no group differences on Vocabulary. Glucocorticoid abnormality, including treatment effects, could be responsible for the reduced Digit Span performance in children with CAH. Other factors related to CAH, such as salt-wasting crises, could also be involved. Additional research is needed to identify the cause of the memory reduction, which will help to determine if more rapid diagnosis or more precise glucocorticoid treatment would help prevent memory reduction. Educational interventions might also be considered for children with CAH. PMID:25496755

    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.

    Several studies have described brain white matter abnormalities on magnetic resonance imaging (MRI) in children and adults with congenital adrenal hyperplasia (CAH), while the brain MRI findings of newborn infants with CAH have not been clarified. We report a newborn boy with CAH who presented brain white matter abnormality on MRI. He was diagnosed as having salt-wasting CAH with a high 17-OHP level at neonatal screening and was initially treated with hydrocortisone at 8 days of age. On day 11 after birth, he had a generalized tonic seizure. No evidence of serum electrolyte abnormalities was observed. Brain MRI revealed white matter abnormalities that consisted of bilateral small diffuse hyperintensities on T1-weighted images with slightly low intensity on T2-weighted images in the watershed area. Several factors associated with brain white matter abnormalities in adults with CAH, such as increasing age, hypertension, diabetes and corticosteroid replacement, were not applicable. Although the cause of the phenomenon in this case is unclear, brain white matter abnormality could be observed in newborn infants with CAH as well as in adult patients.

    Both prenatal and circulating testosterone and other androgens have been suggested to influence the individual's propensity to commit crime, but empirical evidence is limited and inconsistent. Congenital Adrenal Hyperplasia (CAH) and Polycystic Ovary Syndrome (PCOS) are both hyperandrogenic conditions but with an important difference; whereas subjects with CAH are exposed to high concentrations of androgens in utero, women with PCOS are subjected to high androgens in adulthood. Comparing these groups can therefore yield important insights of androgenic effects on behavior. In the current study, information on medical diagnoses and convicted crimes were gathered from Swedish population-based registers. The associations between diagnoses of CAH or PCOS and any crime, violent crime or sex crime were estimated with conditional logistic regression. Results showed that CAH in women and men did not predict criminality, whereas an increased risk for any crime and violent crime was found in PCOS women. Our findings indicate that female hyperandrogenism in adulthood, but not prenatal hyperandrogenism, is associated with risk for criminal behavior. Further research into hyperandrogenic conditions holds opportunities to deepen our understanding of the etiology of crime and psychopathology.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    Female patients with congenital adrenal hyperplasia (CAH; N = 33; 11-41 years), simple-virilizing (SV) patients (N = 19), salt-wasting (SW) patients (N = 13), and sister controls (N = 14) were compared with regard to their body positions and movement patterns. Data collection comprised both self assessments and mothers' assessments using 20 sex-dimorphic items with corresponding "more masculine" and "more feminine" versions for each variable, represented in photographs (forced-choice approach). Primarily based on mothers' assessments, single-item results suggested slightly more masculine positions and patterns for female CAH patients compared to sisters, for SW patients more distinct than for SV patients. Results from an 11-item scale ("motor behavior", alpha = 0.59) revealed differences between SW (more masculine) and SV patients for self assessments (P, one-tailed, < 0.09); sisters were in an intermediate position closer to the SV patients. According to mothers' assessments, the CAH patient group as a whole differed (more masculine) from sisters (P < 0.06); this finding was mainly accounted for by the SW group (P < 0.04). Complex analyses on the relationship of motor behavior and intervening variables (e.g., postnatal androgenization, onset of puberty, menarche, height, weight, sexual orientation) revealed very few significant results. Findings rather suggested organizational hormonal effects on body positions and movements prenatally; they are in line with main results from the interview section of the Hamburg CAH study (e.g., "Gender-related behavior"). An approach of this kind seems to be justified for investigating motor behavior in future psychoendocrine studies.

    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

    Thirty-five female patients with congenital adrenal hyperplasia (CAH) were compared to a group of 16 healthy sisters in regard to gender-related behavioral patterns, present attitudes, and plans for the future. A semi-structured interview with the subjects, ages 11 to 41 yr, and their mothers concentrated on four to five age stages. Results of retrospective data from single items as well as from several related composite scales ("interests and behavior," "appearance," "overall scores") revealed significant group differences: Both in mother-assessment and self-assessment, CAH patients showed a "more masculine" orientation than their sisters, but this was far from consistent across all age stages, especially for single items. Unexpectedly, the gender-behavior differences between CAH patients and sisters did not hold for certain items and scales of "social behavior" (e.g., assertiveness, dominance, acceptance in peer groups) and, in contrast to some of the existing literature, also not for "high-energy expenditure." With regard to expectations for the future, CAH patients had less of a "wish to have their own children" and a higher preference for "having a career versus staying at home." Age, socioeconomic status, intelligence, and presence or absence of a sister as possibly intervening psychosocial/demographic factors could not explain the group differences in behavior. Degree of genital masculinization (Prader stages) or "onset and quality" of therapy as measures of pre- and postnatal androgenization, respectively, could also not account for the degree of the "more masculine" orientation in the CAH group. Nevertheless, the overall results are compatible with earlier findings on the masculinizing effects of prenatal androgens on behavior in humans and point to a time period after sexual differentiation of the genitalia and before birth as the most likely one for the effects of prenatal hormones on behavioral masculinization in humans.

    Context: Mutations in the electron donor enzyme P450 oxidoreductase (POR) result in congenital adrenal hyperplasia with apparent combined 17α-hydroxylase/17,20 lyase and 21-hydroxylase deficiencies, also termed P450 oxidoreductase deficiency (PORD). Major clinical features present in PORD are disordered sex development in affected individuals of both sexes, glucocorticoid deficiency, and multiple skeletal malformations. Objective: The objective of the study was to establish a noninvasive approach to prenatal diagnosis of PORD including assessment of malformation severity to facilitate optimized prenatal diagnosis and timely treatment. Design: We analyzed 20 pregnancies with children homozygous or compound heterozygous for disease-causing POR mutations and 1 pregnancy with a child carrying a heterozygous POR mutation by recording clinical and biochemical presentations and fetal ultrasound findings. In 4 of the pregnancies (3 homozygous and 1 heterozygous for disease-causing POR mutations), prenatal analysis of steroid metabolite excretion in maternal urine was carried out by gas chromatography/mass spectrometry during gestational weeks 11–23. Results: Pregnancy complications in our cohort included maternal virilization (6 of 20) with onset in the second trimester. Seven pregnant women presented with low unconjugated estriol at prenatal screening (triple or quadruple antenatal screening test). Overt dysmorphic features were noted in 19 of the 20 babies at birth but observed in only 5 by prenatal ultrasound. These 5 had the most severe malformation phenotypes and poor outcome, whereas the other babies showed normal development. Steroid profiling of maternal urine revealed significantly increased steroids of fetal origin, namely the pregnenolone metabolite epiallopregnanediol and the androgen metabolite androsterone, with concomitant low values for estriol. Diagnostic steroid ratios conclusively indicated PORD as early as gestational week 12. In the heterozygous

    Steroid 3-beta hydroxysteroid dehydrogenase type II (3β-HSD2) deficiency is a rare autosomal recessive form of congenital adrenal hyperplasia (CAH). We report the genetic basis of 3β-HSD2 deficiency arising from uniparental isodisomy (UPD) of chromosome 1. We describe a term undervirilized male whose newborn screen indicated borderline CAH. The patient presented on the 7th day of life in salt-wasting adrenal crisis. Steroid hormone testing revealed a complex pattern suggestive of 3β-HSD deficiency. Chromosomal microarray and single nucleotide polymorphism analysis revealed complete UPD of chromosome 1. Sanger sequencing of HSD3B2 revealed a previously described missense mutation, c.424G>A (p.E142K) in homozygous state, thus confirming the diagnosis of 3β-HSD2 deficiency. We provide evidence of the existence of an uncommon mechanism for HSD3B2 gene-related CAH arising from UPD of chromosome 1. PMID:27796263

    21-hydroxylase deficiency (21-OHD) caused congenital adrenal hyperplasia (CAH) is a group of autosomal recessive genetic disorders resulting from mutations in genes involved with cortisol (CO) synthesis in the adrenal glands. Testicular adrenal rest tumors (TARTs) are rarely the presenting symptoms of CAH. Here, we describe a case of simple virilizing CAH with TARTs, in a 15-year-old boy. The patient showed physical signs of precocious puberty. The levels of blood adrenocorticotropic hormone (ACTH), urinary 17-ketone steroids (17-KS), dehydroepiandrosterone sulfate (DHEA-S), and serum progesterone (PRGE) were elevated, whereas those of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and CO were reduced. Computed tomography (CT) of the adrenal glands and magnetic resonance imaging (MRI) of the testes showed a soft tissue density (more pronounced on the right side) and an irregularly swollen mass (more pronounced on the left side), respectively. Pathological examination of a specimen of the mass indicated polygonal/circular eosinophilic cytoplasm, cord-like arrangement of interstitial cells, and lipid pigment in the cytoplasm. Immunohistochemistry results precluded a diagnosis of Leydig cell tumors. DNA sequencing revealed a hackneyed homozygous mutation, I2g, on intron 2 of the CYP21A2 gene. The patient’s symptoms improved after a three-month of dexamethasone therapy. Recent radiographic data showed reduced hyperplastic adrenal nodules and testicular tumors. A diagnosis of TART should be considered and prioritized in CAH patients with testicular tumors. Replacement therapy using a sufficient amount of dexamethasone in this case helps combat TART.

    A 14-year-old female with classical congenital adrenal hyperplasia because of 21-hydroxylase deficiency underwent bilateral adrenalectomy at 6 years of age as a result of poor hormonal control. Because the patient was adrenalectomized, extra adrenal androgen production was suspected. Imaging studies including pelvic ultrasound and pelvic magnetic resonance imaging (MRI) were obtained to evaluate for adrenal rest tumors of the ovaries. Abdominal MRI was obtained to evaluate for residual adrenal tissue. A cystic lesion arising from her right ovary suspicious for ovarian neoplasm was noted on pelvic MRI. Right salpingo-oophorectomy was performed and histopathological examination revealed ovarian serous adenocarcinoma, low-grade, and well-differentiated. Tumor marker CA-125 was elevated and additional ovarian cancer staging workup confirmed stage IIIC due to one lymph node positive for carcinoma. The patient then developed a large left ovarian cyst, which led to a complete total abdominal hysterectomy and removal of the left ovary and fallopian tube. Pathology confirmed ovarian serous adenocarcinoma with microscopic focus of carcinoma in the left ovary. After numerous complications, the patient responded well to chemotherapy, CA-125 levels fell and no evidence of carcinoma was observed on subsequent imaging. To our knowledge, this is the first reported case of an ovarian serous adenocarcinoma in a patient with CAH. Although rare, we propose that the ovaries were the origin of androgen production and not residual adrenal tissue. The relationship between CAH and ovarian carcinomas has yet to be established, but further evaluation is needed given the poor survival rate of high-grade serous ovarian carcinoma.

    We present a patient with Meige like lymphedema (left lower limb hypoplasia) with asymptomatic minimal accumulation of Technetium-99m sulfur colloid in bilateral breasts. We attribute the possible pathology to accumulation of interstitial fluid in hypoplastic left lower limb leading to dilatation of the remaining outflow tracts and valvular incompetence. This may be causing reversal of flow from subcutaneous tissues into the dermal plexus involving the breast. Other possibilities include formation of spontaneous lymphovenous shunt or lymphatic intercommunication at lower trunk level as a result of increased pressure leading to minimal lymph accumulation in breasts. Later a mammogram was performed which was found to be normal. MR also confirmed no cisterna chyli abnormalities or aberrant lymphatic channels in lower thorax region that may be the explanation for the abnormal sulphur colloid uptake in both breasts.

    Background: Congenital adrenal hyperplasia (CAH) due to mutations in the gene encoding 21-hydroxilase is one of common disease with an autosomal recessive form. In this study, our aim is to detect the prevalence of eight common mutations in nonclassical congenital adrenal hyperplasia (NCAH). Materials and Methods: A total of 30 patients with clinical and laboratory evidence of NCAH was selected. Gene-specific polymerase chain reaction (PCR) without contamination of pseudogene was carried out, and PCR product of this step was used to amplification-refractory mutation system PCR on eight common mutations in CYP21A2 gene. Results: Two heterozygote patients for I2G mutation and six heterozygote patients for Q318X mutation is reported in our study. These mutations associated with the classic form of CAH, and heterozygotes presented with NC symptom, including premature pubarche and hirsutism. Conclusion: There are some data about the association of the mutation with the clinical form of CAH including classic (salt-wasting and simple virilizing) and NC form. I2G and Q318X mutations were reported in classic form in homozygote state, but the heterozygote form associated with NC form. CAH diagnosis with NC symptom and with measurement of 17-hydroxyprogestrone as NCAH is not a trusted assessment and require to molecular analysis for accurate diagnosis. PMID:27099846

  9. Adrenal insufficiency.

    PubMed

    Auron, Moises; Raissouni, Nouhad

    2015-03-01

    Adrenal insufficiency is a life-threatening condition that occurs secondary to impaired secretion of adrenal glucocorticoid and mineralocorticoid hormones. This condition can be caused by primary destruction or dysfunction of the adrenal glands or impairment of the hypothalamic-pituitary-adrenal axis. In children, the most common causes of primary adrenal insufficiency are impaired adrenal steroidogenesis (congenital adrenal hyperplasia) and adrenal destruction or dysfunction (autoimmune polyendocrine syndrome and adrenoleukodystrophy), whereas exogenous corticosteroid therapy withdrawal or poor adherence to scheduled corticosteroid dosing with long-standing treatment constitute the most common cause of acquired adrenal insufficiency. Although there are classic clinical signs (eg, fatigue, orthostatic hypotension, hyperpigmentation, hyponatremia, hyperkalemia, and hypoglycemia) of adrenal insufficiency, its early clinical presentation is most commonly vague and undefined, requiring a high index of suspicion. The relevance of early identification of adrenal insufficiency is to avoid the potential lethal outcome secondary to severe cardiovascular and hemodynamic insufficiency. The clinician must be aware of the need for increased corticosteroid dose supplementation during stress periods.

  10. Embryological and molecular development of the adrenal glands.

    2015-03-01

    In this mini review, the embryological and functional development of the adrenal glands is presented from a molecular perspective. While acknowledging that this is a highly complex series of events, the processes are described in simple and broad strokes in a single text for the reader who is interested in this field but is not an active researcher. The origin of the adrenal glands is in the mesodermal ridge as early as the fourth week of gestation. Between the eighth and ninth weeks of gestation, the adrenal glands are encapsulated and this results in the presence of a distinct organ. There have been great strides in deciphering the very complicated molecular aspects of adrenal gland development in which multiple transcription factors have been identified, directing the adrenogonadal primordium into the adrenal cortex, kidney, or bipotential gonad. Adrenocorticotrophic hormone is critical for early development of the hypothalamic-pituitary adrenal axis. Several mutations in transcription factors, responsible for normal adrenal gland development have been found to induce the familial syndrome of congenital adrenal hypoplasia or neoplasia.

    X-linked Adrenal Hypoplasia Congenita (AHC) is caused by deletions or point mutations in the NR0B1 (DAX1) gene. We present a boy with AHC who came at the age of 25 days in a severe state due to prolonged vomiting and progressive dehydration. Laboratory studies showed prominent hyponatremia and hyperkaliemia but not hypoglycemia. Primary adrenal insufficiency was confirmed with low serum cortisol levels and high plasma ACTH levels. Hydrocortisone therapy combined with saline and glucose infusions was started immediately after blood collection. Two exons of the NR0B1 (DAX1) gene were impossible to amplify using the standard PCR method. Array CGH was used to confirm the putative copy-number variation of NR0B1 (DAX1) revealing a novel hemizygous deletion encompassing the entire NR0B1 (DAX1) gene together with the MAGEB genes. This genetic defect was also present in heterozygosity in the patient's mother. We show that NR0B1 (DAX1) gene analysis is important for confirmation of AHC diagnosis and highlights the role of genetic counseling in families with AHC patients, particularly those with X chromosome microdeletions, covering more than NR0B1 (DAX1) alone. We hope that further clinical follow-up of this patient and his family will shed a new light on the role of MAGEB genes. PMID:27656210

    Congenital hyperinsulinism (CHI) caused by a glucokinase- (GCK-) activating mutation shows autosomal dominant inheritance, and its severity ranges from mild to severe. A 43-year-old female with asymptomatic hypoglycemia (47 mg/dL) was diagnosed as partial adrenal insufficiency and the administration of hydrocortisone (10 mg/day) was initiated. Twelve years later, her 8-month-old grandchild was diagnosed with CHI. Heterozygosity of exon 6 c.590T>C (p.M197T) was identified in a gene analysis of GCK, which was also detected in her son and herself. The identification of GCK-activating mutations in hyperinsulinemic hypoglycemia patients may be useful for a deeper understanding of the pathophysiology involved and preventing unnecessary glucocorticoid therapy.

    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.

    Gender-typed behaviors and interests were investigated in 26 girls, aged 2-10 years, affected with congenital adrenal hyperplasia (CAH) and in 26 unaffected girls matched for age. Girls with CAH were more interested in masculine toys and less interested in feminine toys and were more likely to report having male playmates and to wish for masculine careers. Parents of girls with CAH rated their daughters' behaviors as more boylike than did parents of unaffected girls. A relation was found between disease severity and behavior indicating that more severely affected CAH girls were more interested in masculine toys and careers. No parental influence could be demonstrated on play behavior, nor did the comparison of parents' ratings of wished for behavior versus perceived behavior in their daughters indicate an effect of parental expectations. The results are interpreted as supporting a biological contribution to differences in play behavior between girls with and without CAH.

    We investigated the effects of type of congenital adrenal hyperplasia (CAH), treatment, endocrinological, surgical, and socio-demographic factors as well as patients' body perception on the gender-typed play and behavioral and emotional problems in female children with CAH. The sample included 28 females with CAH (mean age: 12.6 years). We compared patients with CAH to 28 age-matched patients with type 1 diabetes mellitus and 28 healthy controls. Patients with CAH had significantly higher externalization and total problems scores and were less interested in typically female behaviors. The behavioral and emotional problems in patients with CAH were associated with patient satisfaction with the appearance of their genitalia, the surgeons' assessment of the success of the surgical procedures, and mean testosterone level. Our results showed the severity of the behavioral and emotional problems was associated with severity of androgenization, patients' perception of their genitalia and the surgical outcome.

    In July 1998, Cortef oral suspension (Pharmacia & Upjohn) was reformulated changing the suspending agent tragacanth to xanthan gum. We subsequently observed suboptimal control of hormone levels in a group of children with classic congenital adrenal hyperplasia, despite increasing doses of Cortef suspension and stringent instructions to parents regarding shaking of the bottles of medication. Nineteen children receiving Cortef and fludrocortisone therapy were changed to hydrocortisone tablets and fludrocortisone, with a 10 percent reduction in hydrocortisone dose. A significant decrease in 17-hydroxyprogesterone (235 +/- 120 vs. 27 +/- 7 nmol/L; pcongenital adrenal hyperplasia. Cortef suspension has been recalled as a result of these data.

    An essential component of regulated steroidogenesis is the translocation of cholesterol from the cytoplasm to the inner mitochondrial membrane where the cholesterol side-chain cleavage enzyme carries out the first committed step in steroidogenesis. Recent studies showed that a 30-kDa mitochondrial phosphoprotein, designated steroidogenic acute regulatory protein (StAR), is essential for this translocation. To allow us to explore the roles of StAR in a system amenable to experimental manipulation and to develop an animal model for the human disorder lipoid congenital adrenal hyperplasia (lipoid CAH), we used targeted gene disruption to produce StAR knockout mice. These StAR knockout mice were indistinguishable initially from wild-type littermates, except that males and females had female external genitalia. After birth, they failed to grow normally and died from adrenocortical insufficiency. Hormone assays confirmed severe defects in adrenal steroids-with loss of negative feedback regulation at hypothalamic-pituitary levels-whereas hormones constituting the gonadal axis did not differ significantly from levels in wild-type littermates. Histologically, the adrenal cortex of StAR knockout mice contained florid lipid deposits, with lesser deposits in the steroidogenic compartment of the testis and none in the ovary. The sex-specific differences in gonadal involvement support a two-stage model of the pathogenesis of StAR deficiency, with trophic hormone stimulation inducing progressive accumulation of lipids within the steroidogenic cells and ultimately causing their death. These StAR knockout mice provide a useful model system in which to determine the mechanisms of StAR's essential roles in adrenocortical and gonadal steroidogenesis.

    P450c17 enzyme catalyses two different reactions: the 17α-hydroxylation of progesterone and pregnenolone, and segmenting the carbon 17-20 binding from the 17,20lyase producing adrenal androgens. This enzyme is coded by the CYP17A1 gene. The case is presented of a 14 year old patient with delayed pubertal development and a high blood pressure for height and age. 46,XX karyotype. Hormonal studies highlighted hypergonadotropic hypogonadism, adrenal insufficiency and mineralocorticoid excess. Subsequent genetic studies showed a homozygous mutation in the CYP17A1 gene (c.753+G>A), not previously described, which is responsible for the pathophysiology of 17α-hydroxylase deficiency. This entity is a rare form of congenital adrenal hyperplasia. The disease often goes unnoticed until adolescence or early adult life, and should be suspected in 46,XY individuals with ambiguous genitalia or 46,XX with delayed puberty associated with hypertension and/or hypokalaemia.

    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.

    Context Primary adrenal failure is a life-threatening condition that can be caused by a range of etiologies, including autoimmune, metabolic, and developmental disorders. The nuclear receptors DAX1 (NR0B1) and steroidogenic factor-1 (SF1/Ad4BP, NR5A1) play an important role in adrenal development and function, and mutations in these transcription factors have been found in patients with adrenal hypoplasia. Objective To investigate the prevalence of DAX1 and SF1 mutations in children and adults with primary adrenal failure of unknown etiology (i.e., not caused by congenital adrenal hyperplasia, adrenoleukodystrophy, autoimmune disease). Patients One-hundred and seventeen patients were included. Eighty-eight individuals presented in infancy or childhood with adrenal hypoplasia or primary adrenal failure of unknown etiology (n=64, 46,XY phenotypic males; n=17, 46,XY gonadal dysgenesis/impaired androgenization; n=7, 46,XX females). Twenty-nine individuals presented in adulthood with “Addison disease” of unknown etiology. Methods Mutational analysis of DAX1 (NR0B1) (including exon 2α/1A) and SF1 (NR5A1) by direct sequencing. Results DAX1 mutations were found in 58% (37/64) of 46,XY phenotypic boys referred with adrenal hypoplasia, and in all boys (8/8) with hypogonadotropic hypogonadism and a family history suggestive of adrenal failure in males. SF1 mutations causing adrenal failure were found only in two patients with 46,XY gonadal dysgenesis. No DAX1 or SF1 mutations were identified in the adult-onset group. Conclusions DAX1 mutations are a relatively frequent cause of adrenal failure in this group of boys. SF1 mutations causing adrenal failure in humans are rare and are more likely to be associated with significant underandrogenization and gonadal dysfunction in 46,XY individuals. PMID:16684822

    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 nonclassical CAH. However, it is known that a given mutation can associate with different clinical phenotypes, resulting in a high rate of genotype-phenotype nonconcordance. We aimed to study the genotype-phenotype nonconcordance in a family with three siblings affected with nonclassical CAH. All had hormonal evidence of nonclassical 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 siblings a second, rare c.1097G>A (p.R366H) mutation in exon 8. Computational modeling confirmed that this was a mild mutation consistent with nonclassical CAH. We recommend that sequencing of entire genes for rare mutations should be carried out when genotype-phenotype nonconcordance is observed in patients with autosomal recessive monogenic disorders, including CAH.

    Case Description: It is presented the phenotype of a new compound heterozygous mutation of the genes R384X and Q356X encoding the enzyme of 11-beta-hydroxylase Clinical Findings: Severe virilization, peripheral hypertension, and early puberty. Treatment and Outcome: Managed with hormone replacement therapy (corticosteroid) and antihypertensive therapy (beta-blocker), resulting in the control of physical changes and levels of arterial tension. Clinical Relevance: According to the phenotypic characteristics of the patient, it is inferred that the R384X mutation carries an additional burden on the Q356X mutation, with the latter previously described as a cause of 11-beta-hydroxylase deficiency. The description of a new genotype, as in this case, expands the understanding of the hereditary burden and deciphers the various factors that lead to this pathology as well as the other forms of congenital adrenal hyperplasia (CAH), presenting with a broad spectrum of clinical presentations. This study highlights the importance of a complete description of the patient's CAH genetic profile as well as their parents' genetic profile. PMID:27821898

    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.

    Summary Steroid hormones modulate memory in animals and human adults. Little is known on the developmental effect 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 to 14 years) completed the study. Subjects were presented positive, negative and neutral pictures. Memory recall occurred about 30 minutes after viewing the pictures. Children with CAH showed memory deficits for negative pictures compared to healthy children (p < 0.01). There were no group differences on memory performance for either positive or neutral pictures (p’s >0.1). 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. PMID:18162329

    Prenatal treatment of pregnancies at risk of congenital adrenal hyperplasia (CAH) may prevent ambiguous genitalia in female fetuses. We present the prenatal treatment performed in an extended family with two mutations. The proband, a boy with CAH-salt losing form, and his relatives were studied. The proband's paternal uncles/aunts were married to the maternal aunts/uncles, respectively. The relatives had normal basal and stimulated 17OHProgesterone levels, which did not clarify their carrier status. The CYP21A2 gene was sequenced. The proband and the paternal relatives harbored a Q318X, R483W mutation in one allele. The maternal relatives and the proband exhibited an R483 frameshift mutation. Early dexamethasone treatment was given during two pregnancies and stopped when male gender was confirmed by early ultrasonography Both newborns were healthy and had normal 17OHProgesterone levels. This family had three mutations which abolish the 21-hydroxylase activity. Two mutations were detected in codon 483 of CYP21A2 gene, exon 10, which have not been reported previously in Latin-America. The molecular study performed in this family allowed us to give an appropriate genetic counseling and prenatal treatment.

    Females with the classic form of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency are said to perform better than unaffected female controls on tests of mental rotation or other visuospatial abilities, but findings are conflicting. We studied 31 adolescents and young adults with CAH and 19 unaffected sibling controls, who were given standardized spatial tests and tests of other sexually differentiated cognitive functions (verbal fluency, perceptual speed). The possible role of CAH subtype (salt-wasting or simple-virilizing) was evaluated. Only females with the more severe, salt-wasting form of CAH, but not females with the simple-virilizing form, performed significantly better than sex-matched sibling controls on measures of mental rotation. Subtype differences were not significant for verbal fluency or perceptual speed. Severity of prenatal genital virilization, but not postnatal age when medication was started, predicted accuracy on the Mental Rotations Test. Results are consistent with the possibility of an organizational effect of androgens in the central nervous system that impacts the development of spatial abilities. Implications for the timing of the hypothetical critical period are discussed.

    Background/Aims Youth with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency develop cardiovascular disease (CVD) risk factors of obesity and hypertension. Carotid intima-media thickness (CIMT), a marker of CVD risk, is increased in CAH young adults. We examined CIMT and its relationship with androgens and obesity in adolescents/young adults with CAH. Methods Twenty CAH subjects (16 ± 3.3 yr, 50% female) and 20 matched controls were studied cross-sectionally. Eight additional obese CAH were included in within-group comparisons. CIMT by high-resolution ultrasound, androgens, anthropometry, bone age (BA), and metabolic/inflammatory markers were assessed. Results Within CAH, CIMT correlated with 17-hydroxyprogesterone (r = 0.48, P < 0.05) and androstenedione (r = 0.46, P < 0.05), and was greater in obese subjects. CIMT was greater in CAH males than females, but similar among CAH females with advanced BA, CAH males with normal BA, and control males. There was no difference in CIMT between CAH and controls, although HDL was inversely correlated with CIMT in both groups. Conclusion CIMT is associated with increased androgens in CAH adolescents and young adults, with loss of sex differences in CAH females with excess androgen exposure. Our findings highlight the importance of hormonal control for CVD prevention in CAH. PMID:26933879

    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.

    Congenital adrenal hyperplasia (CAH) is the commonest cause of ambiguous genitalia for female newborns and is one of the conditions under the umbrella term of "Disorders of Sex Development" (DSD). Management of these patients require multidisciplinary collaboration and is challenging because there are many aspects of care, such as the most appropriate timing and extent of feminizing surgery required and attention to psychosexual, psychological, and reproductive issues, which still require attention and reconsideration, even in developed nations. In developing nations, however, additional challenges prevail: poverty, lack of education, lack of easily accessible and affordable medical care, traditional beliefs on intersex, religious, and cultural issues, as well as poor community support. There is a paucity of long-term outcome studies on DSD and CAH to inform on best management to achieve optimal outcome. In a survey conducted on 16 patients with CAH and their parents in a Malaysian tertiary center, 31.3% of patients stated poor knowledge of their condition, and 37.5% did not realize that their medications were required for life. This review on the research done on quality of life (QOL) of female patients with CAH aims: to discuss factors affecting QOL of female patients with CAH, especially in the developing population; to summarize the extant literature on the quality of life outcomes of female patients with CAH; and to offer recommendations to improve QOL outcomes in clinical practice and research.

  12. Effects of early androgens on sex-typed activities and interests in adolescents with congenital adrenal hyperplasia.

    The goal of this study was to examine the relation of early androgen exposure to sex-typed activities and interests in adolescence. Participants aged 9-19 years included 24 girls and 18 boys with congenital adrenal hyperplasia (CAH) and 16 unaffected sisters and 24 unaffected brothers who served as controls. Using standardized questionnaires, adolescents reported on their participation in sex-typed activities and interest in sex-typed occupations, and parents reported on the adolescents' activities. As hypothesized, girls with CAH showed sex-atypical preferences: increased interest in male-typical activities and careers and reduced interest in female-typical activities and careers compared to the unexposed control girls. These results extend findings of sex-atypical play in young girls with CAH and suggest that the sex-atypical activities and interests of females with CAH reflect direct effects of androgens on the developing brain rather than social responses to virilized genitalia. These results also suggest that population sex differences in activities and interests arise in part from sex differences in early androgens.

    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.

    Patients with rare and complex diseases such as congenital adrenal hyperplasia (CAH) often receive fragmented and inadequate care unless efforts are coordinated among providers. Translating the concepts of the medical home and comprehensive health care for individuals with CAH offers many benefits for the affected individuals and their families. This manuscript represents the recommendations of a 1.5 day meeting held in September 2009 to discuss the ideal goals for comprehensive care centers for newborns, infants, children, adolescents, and adults with CAH. Participants included pediatric endocrinologists, internal medicine and reproductive endocrinologists, pediatric urologists, pediatric surgeons, psychologists, and pediatric endocrine nurse educators. One unique aspect of this meeting was the active participation of individuals personally affected by CAH as patients or parents of patients. Representatives of Health Research and Services Administration (HRSA), New York-Mid-Atlantic Consortium for Genetics and Newborn Screening Services (NYMAC), and National Newborn Screening and Genetics Resource Center (NNSGRC) also participated. Thus, this document should serve as a “roadmap” for the development phases of comprehensive care centers (CCC) for individuals and families affected by CAH. PMID:21274448

    Stigma defined as "undesired differentness" (Goffman, 1963) and subtyped as "experienced" or "enacted," "anticipated," and "internalized" has been documented for patients with diverse chronic diseases. However, no systematic data exist on the association of stigma with somatic intersexuality. The current report concerns women with classical congenital adrenal hyperplasia (CAH), the most prevalent intersex syndrome, and provides descriptive data on CAH-related stigma as experienced in the general social environment (excluding medical settings and romantic/sexual partners) during childhood, adolescence, and adulthood. A total of 62 adult women with classical CAH [41 with the salt-wasting (SW) variant and 21 with the simple-virilizing (SV) variant] underwent a qualitative retrospective interview, which focused on the impact of CAH and its medical treatment on many aspects of women's lives. Deductive content analysis was performed on the transcribed texts. The women's accounts of CAH-related stigma were identified and excerpted as vignettes, and the vignettes categorized according to social context, stigma type, and the associated features of the CAH condition. Nearly two-thirds of women with either variant of CAH provided stigma vignettes. The vignettes included all three stigma types, and most involved some somatic or behavioral feature related to sex or gender. Stigma situations were reported for all ages and all social contexts of everyday life: family, peers, colleagues at work, strangers, and the media. We conclude that there is a need for systematic documentation of stigma in intersexuality as a basis for the development of improved approaches to prevention and intervention.

    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 (p<0.01). There were no group differences on memory performance for either positive or neutral pictures (p>0.1). 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.

    The salivary concentration of 17-hydroxyprogesterone (17-OHP) was determined in 11 patients (aged 6 months to 13 years) with congenital adrenogenital syndrome (AGS) due to C21-hydroxylase deficiency and six healthy controls, in order to assess its value in monitoring treatment of AGS. Salivary 17-OHP was measured by a specific radioimmunoassay after extraction with dichloromethane. Only 100 microliters of saliva was needed for the assay. There was a good correlation (r = 0.93; P less than 0.01) between 17-OHP concentrations in paired saliva and serum samples from the patients and the control subjects. There was a wide scatter in salivary 17-OHP levels in the range between 164 ng/l (1.7 ng/ml in serum) of satisfactorily or overtreated patients and 15,500 ng/l (247 ng/l in serum) of undertreated patients. Levels in normal children were between 200 and 300 ng/l. It is concluded that treatment of congenital AGS (21-hydroxylase deficiency) can be carefully monitored in children with the noninvasive, frequently repeatable measurement of salivary 17-OHP.

    Patients with adrenal insufficiency, genital anomalies and bony malformations resembling the Antley- Bixler syndrome (a craniosynostosis syndrome), are likely to have P450 oxidoreductase (POR) deficiency. Since our first report in 2004, about 26 recessive POR mutations have been identified in 50 patients. POR is the obligate electron donor to all microsomal (type II) P450 enzymes, including the steroidogenic enzymes CYP17A1, CYP21A2 and CYP19A1. POR deficiency may cause disordered sexual development manifested as genital undervirilization in 46,XY newborns as well as overvirilization in those who are 46,XX. This may be explained by impaired aromatization of fetal androgens which may also lead to maternal virilization and low urinary estriol levels during pregnancy. A role for the alternate 'backdoor' pathway of androgen biosynthesis, leading to dihydrotestosterone production bypassing androstenedione and testosterone, has been suggested in POR deficiency but remains unclear. POR variants may play an important role in drug metabolism, as most drugs are metabolized by hepatic microsomal P450 enzymes. However, functional assays studying the effects of specific POR mutations on steroidogenesis showed that several POR variants impaired CYP17A1, CYP21A2 and CYP19A1 activities to different degrees, indicating that each POR variant must be studied separately for each potential target P450 enzyme. Thus, the impact of POR mutations on drug metabolism by hepatic P450s requires further investigation.

    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.

    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.

    The salt-wasting (SW) and simple-virilizing (SV) forms of congenital adrenal hyperplasia (CAH) are characterized by distinct prenatal hormonal milieus. To test whether these hormonal milieus differentially influence the development of a "more masculine" behavioral pattern in female CAH patients (Dittmann et al., 1990), SW patients (N = 13) were compared both to SV patients (N = 20) and healthy sisters of both groups (N = 16). The data are based on semi-structured interviews in which subjects (11-41 yr) and mothers were asked about aspects of "Gender-related interests and behavior," "Level of activity," "Social behavior," (reflecting e.g., assertiveness, dominance, and acceptance by peer groups) and "Appearance"; these areas of interest were represented by composite scales. On most scales, and by both mother-assessment and self-assessment, SW patients differed significantly from both SV patients and sisters in having a "more masculine" orientation. SW patients also showed a higher "Level of activity." These SW group results probably account for much of the CAH/sister differences reported in the companion article (Dittmann et al., 1990). In contrast, SV patients differed from the sister sample on only a few scales. There were no significant differences between SV and SW subjects in the degree of virilization of the external genitalia (indicating no group difference in prenatal androgenization). SW patients were treated "earlier" and "better" after birth (indicating less postnatal androgenization). However, these medical conditions, as well as several psychosocial/demographic variables, could not explain the group behavioral differences. These results do not support a primarily psychosocial explanation of behavioral development in CAH patients, especially those with the SW condition; they rather suggest differential organizational effects of two different hormonal environments (SV vs. SW) during critical periods of prenatal CNS development.

    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.

    Influences of prenatal androgen exposure on human sex-typical behavior have been established largely through studies of individuals with congenital adrenal hyperplasia (CAH). However, evidence that addresses the potential confounding influence of parental socialization is limited. Parental socialization and its relationship to sex-typical toy play and spatial ability were investigated in two samples involving 137 individuals with CAH and 107 healthy controls. Females with CAH showed more boy-typical toy play and better targeting performance than control females, but did not differ in mental rotations performance. Males with CAH showed worse mental rotations performance than control males, but did not differ in sex-typical toy play or targeting. Reported parental encouragement of girl-typical toy play correlated with girl-typical toy play in all four groups. Moreover, parents reported encouraging less girl-typical, and more boy-typical, toy play in females with CAH than in control females and this reported encouragement partially mediated the relationship between CAH status and sex-typical toy play. Other evidence suggests that the reported parental encouragement of sex-atypical toy play in girls with CAH may be a response to the girls' preferences for boys' toys. Nevertheless, this encouragement could further increase boy-typical behavior in girls with CAH. In contrast to the results for toy play, we found no differential parental socialization for spatial activities and little evidence linking parental socialization to spatial ability. Overall, evidence suggests that prenatal androgen exposure and parental socialization both contribute to sex-typical toy play.

    Congenital adrenal hyperplasia (CAH) comprises a group of autosomal recessive disorders caused by an enzymatic deficiency which impairs the biosynthesis of cortisol and, in the majority of severe cases, also the biosynthesis of aldosterone. Approximately 95% of all CAH cases are caused by mutations in the steroid 21-hydroxylase gene (CYP21A2). The CYP21A2 gene and its inactive pseudogene (CYP21A1P) are located within the HLA class III region of the major histocompatibility complex (MHC) locus on chromosome 6p21.3. In this study, we describe chimeric CYP21A1P/CYP21A2 genes detected in our patients with 21-hydroxylase deficiency (21OHD). Chimeric CYP21A1P/CYP21A2 genes were present in 171 out of 508 mutated CYP21A2 alleles (33.8%). We detected four types of chimeric CYP21A1P/CYP21A2 genes: three of them have been described previously as CH-1, CH-3, CH-4, and one type is novel. The novel chimeric gene, termed CH-7, was detected in 21.4% of the mutant alleles. Possible causes of CYP21A1P/CYP21A2 formation are associated with 1) high recombination rate in the MHC locus, 2) high recombination rate between highly homologous genes and pseudogenes in the CYP21 gene area, and 3) the existence of chi-like sequences and repetitive minisatellite consensus sequences in CYP21A2 and CYP21A1P which play a role in promoting genetic recombination.

    Girls and women with classical congenital adrenal hyperplasia (CAH) experience elevated androgens prenatally and show increased male-typical development for certain behaviors. Further, individuals with CAH receive glucocorticoid (GC) treatment postnatally, and this GC treatment could have negative cognitive consequences. We investigated two alternative hypotheses, that: (a) early androgen exposure in females with CAH masculinizes (improves) spatial perception and quantitative abilities at which males typically outperform females, or (b) CAH is associated with performance decrements in these domains, perhaps due to reduced short-term-memory (STM). Adolescent and adult individuals with CAH (40 female and 29 male) were compared with relative controls (29 female and 30 male) on spatial perception and quantitative abilities as well as on Digit Span (DS) to assess STM and on Vocabulary to assess general intelligence. Females with CAH did not perform better (more male-typical) on spatial perception or quantitative abilities than control females, failing to support the hypothesis of cognitive masculinization. Rather, in the sample as a whole individuals with CAH scored lower on spatial perception (p ≤ .009), a quantitative composite (p ≤ .036), and DS (p ≤ .001), despite no differences in general intelligence. Separate analyses of adolescent and adult participants suggested the spatial and quantitative effects might be present only in adult patients with CAH; however, reduced DS performance was found in patients with CAH regardless of age group. Separate regression analyses showed that DS predicted both spatial perception and quantitative performance (both p ≤ .001), when age, sex, and diagnosis status were controlled. Thus, reduced STM in CAH patients versus controls may have more general cognitive consequences, potentially reducing spatial perception and quantitative skills.

    In about 95% of cases, congenital adrenal hyperplasia (CAH) is caused by mutations in CYP21A2 gene encoding steroid 21-hydroxylase (21OH). Recently, we have reported four novel CYP21A2 variants in the Norwegian population of patients with CAH, of which p.L388R and p.E140K were associated with salt wasting (SW), p.P45L with simple virilising (SV) and p.V211M+p.V281L with SV to non-classical (NC) phenotypes. We aimed to characterise the novel variants functionally utilising a newly designed in vitro assay of 21OH enzyme activity and structural simulations and compare the results with clinical phenotypes. CYP21A2 mutations and variants were expressed in vitro. Enzyme activity was assayed by assessing the conversion of 17-hydroxyprogesterone to 11-deoxycortisol by liquid chromatography tandem mass spectroscopy. PyMOL 1.3 was used for structural simulations, and PolyPhen2 and PROVEAN for predicting the severity of the mutants. The CYP21A2 mutants, p.L388R and p.E140K, exhibited 1.1 and 11.3% of wt 21OH enzyme activity, respectively, in vitro. We could not detect any functional deficiency of the p.P45L variant in vitro; although prediction tools suggest p.P45L to be pathogenic. p.V211M displayed enzyme activity equivalent to the wt in vitro, which was supported by in silico analyses. We found good correlations between phenotype and the in vitro enzyme activities of the SW mutants, but not for the SV p.P45L variant. p.V211M might have a synergistic effect together with p.V281L, explaining a phenotype between SV and NC CAH.

    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.

    We identified a balanced de novo translocation involving chromosomes Xq25 and 8q24 in an eight year-old girl with a non-progressive form of congenital ataxia, cognitive impairment and cerebellar hypoplasia. Breakpoint definition showed that the promoter of the Protein Tyrosine Kinase 2 (PTK2, also known as Focal Adhesion Kinase, FAK) gene on chromosome 8q24.3 is translocated 2 kb upstream of the THO complex subunit 2 (THOC2) gene on chromosome Xq25. PTK2 is a well-known non-receptor tyrosine kinase whereas THOC2 encodes a component of the evolutionarily conserved multiprotein THO complex, involved in mRNA export from nucleus. The translocation generated a sterile fusion transcript under the control of the PTK2 promoter, affecting expression of both PTK2 and THOC2 genes. PTK2 is involved in cell adhesion and, in neurons, plays a role in axonal guidance, and neurite growth and attraction. However, PTK2 haploinsufficiency alone is unlikely to be associated with human disease. Therefore, we studied the role of THOC2 in the CNS using three models: 1) THOC2 ortholog knockout in C. elegans which produced functional defects in specific sensory neurons; 2) Thoc2 knockdown in primary rat hippocampal neurons which increased neurite extension; 3) Thoc2 knockdown in neuronal stem cells (LC1) which increased their in vitro growth rate without modifying apoptosis levels. We suggest that THOC2 can play specific roles in neuronal cells and, possibly in combination with PTK2 reduction, may affect normal neural network formation, leading to cognitive impairment and cerebellar congenital hypoplasia.

    Girls and women with classical congenital adrenal hyperplasia (CAH) experience elevated androgens prenatally and show increased male-typical development for certain behaviors. Further, individuals with CAH receive glucocorticoid (GC) treatment postnatally, and this GC treatment could have negative cognitive consequences. We investigated two alternative hypotheses, that: (a) early androgen exposure in females with CAH masculinizes (improves) spatial perception and quantitative abilities at which males typically outperform females, or (b) CAH is associated with performance decrements in these domains, perhaps due to reduced short-term-memory (STM). Adolescent and adult individuals with CAH (40 female and 29 male) were compared with relative controls (29 female and 30 male) on spatial perception and quantitative abilities as well as on Digit Span (DS) to assess STM and on Vocabulary to assess general intelligence. Females with CAH did not perform better (more male-typical) on spatial perception or quantitative abilities than control females, failing to support the hypothesis of cognitive masculinization. Rather, in the sample as a whole individuals with CAH scored lower on spatial perception (p ≤ .009), a quantitative composite (p ≤ .036), and DS (p ≤ .001), despite no differences in general intelligence. Separate analyses of adolescent and adult participants suggested the spatial and quantitative effects might be present only in adult patients with CAH; however, reduced DS performance was found in patients with CAH regardless of age group. Separate regression analyses showed that DS predicted both spatial perception and quantitative performance (both p ≤ .001), when age, sex, and diagnosis status were controlled. Thus, reduced STM in CAH patients versus controls may have more general cognitive consequences, potentially reducing spatial perception and quantitative skills.

    Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncinate process. CT and endoscopic examination usually complement each other in diagnosing MSH. PMID:25548709

    Enamel hypoplasia is defined as a break in the continuity of enamel with a reduction in the layers leading to depressions or grooves. Chronological hypoplasia is differentiated from other forms of hypoplasia due to its characteristic presentation (multiple, symmetrical, chronological pattern). Chronological hypoplasias are seen at the time tooth erupts into the oral cavity leading to several problems like aesthetic problems, tooth sensitivity, caries and early pulpal involvement. Prevention of interaction of aetiological factors is not possible because multiple factors are required for enamel synthesis. This paper highlights how to diagnose, intercept and treat chronological hypoplasias. It also mentions reasons for treating a case and different modalities available. PMID:24907208

    2015-03-01

    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.

    We hypothesized that girls with congenital adrenal hyperplasia (CAH), who experience higher than normal levels of androgens prenatally, would show masculinization of behaviors that show sex differences. Therefore, we examined rough-and-tumble play and sex of preferred playmates in 3-8-year-old children with CAH and in unaffected 3-8-year-old male and female relatives. The hypothesized sex differences in rough-and-tumble play were seen, with unaffected boys showing more rough-and-tumble play than unaffected girls. However, CAH girls were similar to unaffected girls. Additionally, CAH boys showed reduced rough-and-tumble play. In contrast, sex of preferred playmates showed the hypothesized pattern of results. There were sex differences, with unaffected boys preferring boys and unaffected girls preferring girls. In addition, the preferences of girls with CAH were masculinized compared to those of unaffected girls. Results are discussed in terms of possible influences of social, hormonal, and illness factors.

    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.

  17. Review of Outcome Information in 46,XX Patients with Congenital Adrenal Hyperplasia Assigned/Reared Male: What Does It Say about Gender Assignment?

    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.

    Clinico-anatomical data of a rare condition congenital oligomeganephronic renal hypoplasia with a glomerulonephritis as a complication are available for a 13-year-old girl who died of chronic renal failure. Large aglomerular zones consisting of primitive canaliculi in a loose stroma were observed in kidneys that were decreased in size. The glomeruli were few in number, some of them of a large size (2-2.5-fold), firmly attached to the capsule, with pronounced extracapillary proliferation.

    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.

    In the era of advocacy groups, it seems appropriate to contemplate how best to utilize them for patient benefit in the management of those with disorders of sex development (DSD), including those with congenital adrenal hyperplasia (CAH). Such interactions, to be constructive, require a spirit of cooperation to optimize outcomes. A traditional view of advocacy groups as a type of defender of patients' rights appears outdated and it is time that the benefits of their participation be fully realized. Open dialogue with all patients/families, including those who feel harmed by prior care are paramount. We discuss several recent examples of interactions that illustrate how dialogue in the name of "advocacy" can have a negative impact on developing a framework for ongoing constructive dialogue and actions. Such approaches completely change the dynamics of subsequent interactions. Physicians involved in the care of individuals with DSD, including those with CAH, and patients should be aware of confrontational techniques and legal implications that may be used by some advocacy groups. Hopefully recent efforts to promote a multidisciplinary care approach for patients with DSD/CAH will continue to foster mutual cooperation between team members, where the common goal is improving patient/family outcomes and quality of life.

    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.

    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.

    Congenital adrenal hyperplasia (CAH) is a chronic condition and individuals are exposed to elevated androgen levels in utero as a result of the endogenous cortisol deficiency. Prenatal androgen exposure has been suggested to influence mental health, but population based studies on psychiatric morbidity among girls and women with CAH are lacking. Therefore, we performed a cohort study based on Swedish nationwide registers linked with the national CAH register. Girls and women with CAH due to 21-hydroxylase deficiency (n = 335) born between January 1915 and January 2010 were compared with aged-matched female (n = 33500) and male controls (n = 33500). Analyses were stratified by phenotype [salt wasting (SW), simple virilizing (SV), and non-classical type (NC)] and by CYP21A2 genotype subgroups (null, I2splice, I172N, and P30L). Results are presented as estimated risks (OR, 95%CI) of psychiatric disorders among girls and women with CAH compared with age-matched controls. Any psychiatric diagnoses were more common in CAH females compared with female and male population controls [1.9 (1.4-2.5), and 2.2 (1.7-2.9)]. In particular, the risk of alcohol misuse was increased compared with female and male population controls [2.8 (1.7-4.7) and 2.1 (1.2-3.5)], and appeared most common among the girls and women with the most severe null genotype [6.7 (2.6-17.8)]. The risk of stress and adjustment disorders was doubled compared with female population controls [2.1 (1.3-3.6)]. Girls and women with CAH have an increased risk of psychiatric disorders in general and substance use disorders in particular compared with unexposed females, with the highest risk among those with the most severe genotype. Prenatal androgen exposure and deficient endogenous cortisol and/or adrenaline production may provide explanations for these findings, but other factors related to CAH cannot be excluded.

    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.

    Pulmonary artery agenesis and hypoplasia of the homolateral lung occasionally occurs as an isolated lesion, but more often has associated congenital cardiac anomalies. We present a case where pulmonary artery agenesis was the sole lesion in an asymptomatic child. Pulmonary artery agenesis should be suspected in asymptomatic patients if a plain chest X-ray shows asymmetric lung fields, lung hypoplasia, or hyperinflation of the contralateral lung. Echocardiography is the best tool to establish the diagnosis. In our opinion, invasive procedures, such as cardiac catheterization, may be postponed if there is no echocardiographic evidence of pulmonary hypertension.

    The computed tomographic appearance of the adrenal gland was studied in 302 patients with possible endocrinologic disease and 107 patients undergoing CT for nonendocrinologic reasons. Measurements of adrenal size were also made in 100 adults with no known adrenal pathology. CT proved to be a sensitive diagnostic tool in combination with clinical studies. When blood hormone levels are increased, CT can differentiate among homogeneous organic hyperplasia, nodular hyperplasia, benign adenoma, and malignant cortical adenoma. When blood hormone levels are decreased, CT can demonstrate hypoplasia or metastatic tumorous destruction. Calcifications can be demonstrated earlier than on plain radiographs. When hormone elimination is increased, the morphologic substrate can be identified; tumorous changes can be localized and infiltration of surrounding organs recognized.

    PubMed

    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.

    The mitochondrial benzodiazepine receptor (mBzR) appears to be a key factor in the flow of cholesterol into mitochondia 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, the authors have cloned the human PBR gene. The 13-kb gene is divided into four exons, with exon 1 encoding only a short 5[prime] untranslated segment. The 5[prime] flanking DNA lacks TATA and CAAT boxes but contains a cluster of SP-1 binding sites, typical of [open quotes]housekeeping[close quotes] genes. The encoded PBR mRNA is alternately spliced into two forms: [open quotes]authentic[close quotes] 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 of 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 [[sup 3]H]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.

    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 < 10 nmol/L), fair control (170HP 10-40 nmol/L or progesterone 1.0-1.5 nmol/L), or poor 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

    We report a new compound heterozygous frameshift mutation in the type II 3{Beta}-hydroxysteroid dehydrogenase (3{beta}-HSD) gene in a Pakistanian female child with the salt-wasting form of 3{Beta}-HSD deficiency congenital adrenal hyperplasia. The etiology for her congenital adrenal hyperplasia was not defined. Although the family history suggested possible 3{beta}-HSd deficiency disorder, suppressed adrenal function caused by excess glucocorticoid therapy in this child at 7 yr of age did not allow hormonal diagnosis. To confirm 3{beta}-HSD deficiency, we sequenced the type II 3{beta}-HSD gene in the patient, her family, and the parents of her deceased paternal cousins. The type II 3{beta}-HSD gene region of a putative promotor, exons I, II, III, and IV, and exon-intron boundaries were amplified by PCR and sequenced in all subjects. The DNA sequence of the child revealed a single nucleotide deletion at codon 318 [ACA(Thr){r_arrow}AA] in exon IV in one allele, and two nucleotide deletions at codon 273 [AAA(Lys){r_arrow}A] in exon IV in the other allele. The remaining gene sequences were normal. The codon 318 mutation was found in one allele from the father, brother, and parents of the deceased paternal cousins. The codon 273 mutation was found in one allele of the mother and a sister. These findings confirmed inherited 3{beta}-HSD deficiency in the child caused by the compound heterozygous type II 3{beta}-HSD gene mutation. Both codons at codons 279 and 367, respectively, are predicted to result in an altered and truncated type II 3{beta}-HSD protein, thereby causing salt-wasting 3{beta}-HSD deficiency in the patient. 21 refs., 2 figs., 1 tab.

    The CT appearance of the adrenal glands was investigated in 30 patients with congenital renal anomalies. The ipsilateral adrenal was clearly identified in 83% of these patients; in all of them, the adrenal was a paraspinal disk-shaped organ, which appeared linear on CT. Conversely, the adrenals retained their normal shape in a control group of 20 patients with acquired renal atrophy or prior simple nephrectomy.

    : Adrenal diseases--including disorders such as Cushing's syndrome, Addison's disease, pheochromocytoma, primary hyperaldosteronism and congenital adrenal hyperplasia--are relatively rare in pregnancy, but a timely diagnosis and proper treatment are critical because these disorders can cause maternal and fetal morbidity and mortality. Making the diagnosis of adrenal disorders in pregnancy is challenging as symptoms associated with pregnancy are also seen in adrenal diseases. In addition, pregnancy is marked by several endocrine changes, including activation of the renin-angiotensin-aldosterone system and the hypothalamic-pituitary-adrenal axis. The aim of this article was to review the pathophysiology, clinical manifestation, diagnosis and management of various adrenal disorders during pregnancy.

    A new-born male presented within 12 h of birth with respiratory distress. On examination and workup, he had palatoglossal fusion, cleft palate and hypoplasia of the cerebellar vermis. A 2.5 Fr endotracheal tube was inserted into the pharynx through nostril as a nasopharyngeal stent, following which his respiratory distress improved. Once child was optimised, then feeding was started by nasogastric tube and feeds were tolerated well. Elective tracheostomy and gastrostomy were done, followed by release of adhesions between the tongue and palate at a later stage. Review of literature suggests that palatoglossal fusion is uncommon and presents as an emergency. Mostly, these oral synechiae are associated with digital and/or cardiac anomaly. Other disorders associated with intra-oral synechiae include congenital alveolar synechiae, van der Woude syndrome, popliteal pterygium syndrome and oromandibular limb hypogenesis syndrome. The authors report a hitherto undescribed association of palatoglossal fusion with cleft palate and hypoplasia of the cerebellar vermis. PMID:27274132

    We describe 10-month-old identical female twin infants, one with primary left-sided pulmonary agenesis and the other with primary left-sided pulmonary hypoplasia. They came to our outpatient clinic complaining of persistent dry cough. The clinical examination revealed decreased air entry over the left hemithorax. Chest x-rays showed complete left-sided radio-opacity in both the twins. The chest computed tomography scan with contrast confirmed the diagnoses of left-sided pulmonary agenesis (twin A) and left-sided hypoplasia (twin B). No other associated congenital anomaly was noted in either of the twins. To our knowledge, such a condition in live monozygotic twins has not been previously reported in published studies.

    The gene CYP21B, encoding the steroid 21-hydroxylase enzyme of adrenal steroid biosynthesis, has been mapped to the human major histocompatibility complex (MHC). Deficiency of this enzyme leads to congenital adrenal hyperplasia (CAH). We report the phenotypes of the HLA and complement C4 and Bf genes, which are closely linked to the CYP21B gene, together with a detailed analysis of the CYP21 and C4 RFLP, in 17 Finnish families with CAH. The RFLP analysis with six restriction enzymes suggested that, altogether, 35% of the affected chromosomes had a CYP21B + C4B gene deletion, 9% an obvious gene conversion of the CYP21B gene to a CYP21A-like gene, and 3% a CYP21A + C4B duplication. The remaining 53% gave the RFLP patterns also found in nonaffected chromosomes. We also found that a 14.0-kb EcoRI RFLP marker of the CYP21 genes was strongly associated with the presence of a short C4B gene, suggesting that some of the RFLP markers found with the CYP21 probe may actually derive from C4B gene polymorphism. Three particular MHC haplotypes, each with a characteristic RFLP pattern, were found in many unrelated families. These three haplotypes accounted for 59% of the affected chromosomes in our study group, the rest (41%) of the affected chromosomes being distributed among various subtypes. The results suggest that, within a single, well-defined population such as in Finland, only a few CYP21B gene defects may constitute a substantial part of the affected chromosomes. This finding will help in genetic studies of CAH in such populations. Images Figure 2 PMID:2565078

    Disorders of the adrenal glands frequently have secondary neurological manifestations, while some diseases that involve the central nervous system are accompanied by adrenal gland dysfunction. Excessive corticosteroid secretions in primary or secondary Cushing's syndrome causes muscle weakness and behavioral disturbances, such as emotional lability and sometimes depression, while adrenal insufficiency may cause fatigue, weakness, and depression. Adrenoleukodystrophy and adrenoneuromyelopathy are X-linked recessive disorders of the metabolism of very long chain fatty acids that manifest with white matter abnormalities of the brain, myelopathy and/or neuropathy, as well as adrenal insufficiency. Other disorders of the adrenal glands include hyperaldosteroidism, which may cause weakness from hypokalemia. Dysfunction of the adrenal medulla causes excessive or deficient secretion of catecholamines, primarily causing cardiovascular symptoms. This chapter reviews the clinical manifestations and diagnostic aspects and treatment of the various disorders of the adrenal glands. Some of the congenital adrenal diseases are also discussed.

    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.

    The human adrenal is an endocrine gland located at the superior part of the kidney. Composed of the adrenal cortex of mesoblastic origin and the adrenal medulla of neuroectoblastic origin, the human fetal adrenal grows considerably during the first three months of development. From 12 to 18 weeks of development (WD), the weight of the adrenals increases seven-fold. The gland's weight doubles from 18 to 28 WD and from 28 to 36 WD. At birth, the two adrenals weigh on average 10 g. At the 8th week, two zones are individualized in the adrenal cortex: the definitive zone and the fetal inner zone. At the second trimester, according to ultrastructural and biochemical studies, a third zone, called the transition zone, is individualized between the definitive zone and the fetal inner zone. The definitive zone persists, but the origin of the three zones (glomerular, fascicular and reticular) of adult adrenal cortex is not known. The fetal inner zone regresses from the 5th month of gestation and disappears totally one year after birth. At the 8th week, the immature neuroblasts migrate to the definitive zone, then to the fetal inner zone to compose the adrenal medulla, which develops essentially after birth and during the first year. Before the 10th week, the human fetal adrenal is able to produce steroid hormones, in particular dehydroepiandrosterone sulfate (DHEA-S); the secretion of cortisol remains discussed. The development of the human fetal adrenal is complex and is under the control of hormones (ACTH, LH and betaHCG), growth factors (ACTH essentially) and transcription factors (essentially SF1 and DAX-1). Knowledge of morphological and molecular phenomena of this development permits to understand the pathophisiology of congenital adrenal deficiencies.

    We studied the biochemical maturity of the lungs of fetuses born to rats exposed to nitrofen on day 9.5 of gestation. In comparison with controls, nitrofen-treated fetuses had pulmonary hypoplasia (decreased lung/body weight), lung hypocellularity (low DNA content) and cellular atrophy (low protein/DNA and phospholipid/DNA) on gestational days 19 and 21. Treated animals with congenital diaphragmatic hernia (CDH) also had cell atrophy and surfactant immaturity (decreased disaturated phosphatidylcholine/DNA) near term. Our data demonstrate that nitrofen causes lung hypoplasia and some degree of surfactant system immaturity that is particularly prominent in fetuses with CDH.

The incidence of these forms in the different geographic areas is dependent of degree of irradication of the tuberculosis. We report the case of a patient with latent chronic adrenal insufficiency of tuberculous origin who was affected for an addisonian crisis during an intercurrent infectious disease, which permitted the diagnosis of the addisonian crisis, and Mal of Pott was moreover detected.

    We present four cases with combined hypoplasia of the cerebellum and the ventral pons-pontocerebellar hypoplasia (PCH). PCH represents an autosomal recessive neurodegenerative disorder with fetal onset. The disease is rare, with less than 20 cases having been reported. The main findings of PCH and the inclusion criteria for our cases can be summarised as progressive microcephaly from birth, pontocerebellar hypoplasia documented by MRI and marked chorea, which may change, later in childhood, to more dystonic patterns. The cerebral cortex becomes progressively atrophic. Motor and mental development are delayed, and epilepsy, mainly tonic-clonic seizures, is frequent. The MRI features in all of our cases were: (1) Hypoplastic cerebellum situated close to the tentorium. The hypoplastic cerebellum has a reduced number of folia, in contrast to the normal number of thin folia in simple cerebellar atrophy. (2) The cerebellar hemispheres are reduced to bean-like or wing-like structures. The cerebellar hemispheres appear to 'float' in the posterior fossa. (3) Markedly hypoplastic ventral pons. (4) Slight atrophy of the supratentorial gyral pattern. (5) Dilated cerebromedullary cistern and fourth ventricle. (6) Delayed myelination of the white matter. (7) No significant disorganisation of brain architecture and no severe corpus callosum defect.

    Focal dermal hypoplasia, caused by mutations in PORCN, is an X-linked ectodermal dysplasia, also known as Goltz syndrome. Only seven cases of unilateral or almost unilateral focal dermal hypoplasia have been reported in the English literature and there have been no previously reported cases in the Republic of Korea. A 19-year-old female presented with scalp defects, skin lesions on the right leg and the right trunk, and syndactyly of the right fourth and fifth toes. Cutaneous examination revealed multiple atrophic plaques and a brown and yellow mass with fat herniation and telangiectasia that was mostly located on the lower right leg. She had syndactyly on the right foot and the scalp lesion appeared to be an atrophic, membranous, fibrotic alopecic scar. A biopsy of the calf revealed upper dermal extension of fat cells, dermal atrophy, and loss of dermal collagen. A diagnosis of almost unilateral focal dermal hypoplasia was made on the basis of physical and histologic findings. Henceforth, the patient was referred to a plastic surgeon and an orthopedics department to repair her syndactyly. PMID:28223754

    Isolated left ventricular (LV) apical hypoplasia is a unusual and recently recognized congenital cardiac anomaly. A 19-year-old man was found to have an abnormal ECG and cardiac murmur identified during a routine health check since joining work. His ECG revealed normal sinus rhythm, right-axis deviation, poor R wave progression, and T wave abnormalities. On physical examination, a 2/6~3/6 systolic murmur was heard at the second intercostal space along the left sternal border. Subsequent echocardiography and cardiac magnetic resonance imaging confirmed the LV apical hypoplasia. Of note, we first found that LV apical hypoplasia was accompanied by RV outflow tract obstruction due to exaggerated rightward bulging of the basal-anterior septum during systole. A close follow-up was performed for the development of heart failure, pulmonary hypertension, and potentially tachyarrhythmia.

    Identification of individuals is the mainstay of any forensic investigation especially in cases of mass disasters when mutilated remains are brought for examination. Dental examination helps in establishing the identity of an individual and thus, has played a vital role in forensic investigation process since long. In this regard, description on the role of enamel hypoplasia is limited in the literature. The present article reviews the literature on the enamel hypoplasia and discusses its utility in forensic identification. Enamel hypoplasia is a surface defect of the tooth crown caused by disturbance of enamel matrix secretion. Enamel defects can be congenital or acquired. In cases of mass disasters, or when the body is completely charred, putrefied and mutilated beyond recognition, the unique dental features can help in identification of the victims. PMID:26097340

    Leber's congenital amaurosis is an autosomal recessive disorder, characterized by the onset of blindness before the age of 6 months, a variable fundus aspect and an absent or extremely pathological ERG. The disorder may be isolated or associated with systemic involvement, such as nephronophtisis (Senior-Loken syndrome), nephronophtisis, cone-shaped epiphyses of the hand and cerebellar ataxia (Saldino-Mainzer syndrome), vermis hypoplasia, oculomotor anomalies and respiratory problems in the neonatal period (Joubert syndrome) or cardiomyopathy. It should be differentiated from other forms or chorioretinal dystrophies (juvenile retinitis pigmentosa or congenital stationary night blindness), cortical blindness or maturation delay and metabolic disorders. Children with possible congenital Leber amaurosis should not only have a thorough ophthalmological examination, but should also be seen by a paediatrician experienced in metabolic disorders.

    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

    A rapid, simple, and specific method was developed for the diagnosis of congenital adrenal hyperplasia (CAH) from dried blood spots on newborn screening cards based on high-performance liquid chromatography/electrospray ionization tandem mass spectrometry (HPLC/ESI-MS/MS). The usefulness of 17 alpha-hydroxyprogesterone (17 OH-P) determination on dried filter-paper blood samples from patients with CAH caused by 21-hydroxylase deficiency was evaluated. The LC/MS/MS detection of 17 OH-P was rapid, <4 min. The intra- and interday accuracy and precision of the method were <7%. Our procedure maintained good linearities (R(2) > 0.992) and recovery rate (>83%). We used this new method to directly determine the 17 OH-P levels in dried blood specimens from abnormal children of various ages, with a detection limit of 20 ng/ml (approximately 240 pg), to avoid the time-consuming derivatization steps required by the gas-chromatography/mass spectrometry (GC/MS) method. Four dried filter-paper blood samples of CAH patients (three girls and one boy, 1-14 years old) were all quantified in an LC/MS/MS study and revealed high 17 OH-P levels (>90 ng/ml). After treatment, all of the elevated 17 OH-P levels either decreased or disappeared. Compared with CAH patients, 17 OH-P was nearly undetectable (<20 ng/ml) in the normal infants by LC/MS/MS. This LC/MS/MS assay is not only useful for both diagnosis and monitoring of treatment of CAH in all other age groups, it also can be used as a screening test for CAH infants. In this study, we provided the first data on 17 OH-P in dried blood specimens affected with CAH using HPLC/ESI-MS/MS.

    Growth-retarded mouse (grt/grt) is a spontaneous mutant that is known as an animal model for primary congenital hypothyroidism caused by resistance to TSH signaling. The regional pattern of cerebral cortical hypoplasia was characterized in grt/grt mice. Ex vivo computed tomography (CT)-based volumetry was examined in four regions of the cerebral cortex, i.e., prefrontal, frontal, parietal and occipito-temporal regions, which were demarcated by structural landmarks on coronal CT images. A region-specific reduced volume of the parietal cortical region covering most of the somatosensory cortex was noted in grt/grt mice rather than in both heterozygous (grt/+) and wild-type (+/+) mice. We concluded that the cortical hypoplasia in grt/grt was seen in identical cortical regions corresponding to human congenital hypothyroidism.

    Unilateral absence of a pulmonary artery is an uncommon congenital heart disease. It can be related to respiratory symptoms such as asthma, an unusual finding in some of these patients. This paper reports the case of a 4-year-old male with recurrent respiratory infections and asthma symptoms, in who further studies found agenesia of right pulmonary artery with pulmonary hypoplasia of the same side.

    Medical imaging of the adrenal glands is an important aspect of the diagnosis of any adrenal gland disorder. This article discusses the normal anatomy and functions of the adrenal glands, as well as specific adrenal gland disorders and how they are diagnosed and treated. Radiologic technologists need to understand the causes, signs, symptoms, diagnosis and management of disorders that prevent the adrenal glands from functioning properly.

    Growth failure and pubertal abnormalities are not uncommon in chronic uncontrolled metabolic diseases like diabetes mellitus. We present a young girl with uncontrolled type 1 diabetes mellitus, who presented with short stature and primary amenorrhea, and on evaluation was found to have anterior pituitary hypoplasia. In addition to uncontrolled diabetes mellitus, she presented with early onset growth failure and lack of spontaneous secondary sexual characteristics. She had central hypothyroidism and inappropriately normal gonadotropin levels. However her serum cortisol levels were normal. MRI of the sellar-suprasellar region revealed a small anterior pituitary gland with thinning of the pituitary stalk consistent with pituitary hypoplasia. While uncontrolled type 1 diabetes itself may cause growth retardation and pubertal abnormalities, this girl had coexisting pituitary maldevelopment - a rare co-existence of two major illnesses of unrelated etiologies. The partial pituitary hormonal deficiency, which spared the hypothalamo-pituitary-adrenal axis, may be due to a transcription factor defect.

    To report on the outcomes of sequential bilateral cochlear implantation (CI) in children with inner ear malformation. The study design is a retrospective case study. The setting is a tertiary reference center. Two children presenting a profound bilateral congenital hearing loss with bilateral hypoplasia of the cochleovestibular nerves and hypoplasic external semicircular canal had a cochlear implant at respectively 16 months and 33 months. A second implant was proposed at respectively 17 and 20 months after the first implant. The main outcome measures are audiometry, perceptive results in closed and open set words (CSW and OSW) and oral production at follow-up. The first cochlear implant gave respectively mean thresholds at 60 dB and 70 dB. Bilateral CI showed mean threshold at respectively 40 dB and 55 dB. In case 1, perceptive assessment was 83% and 70% in respectively CSW and OSW with oral production and comprehension of sentences after 1 year follow-up. In case 2, the perceptive assessment showed no perceptive or linguistic evolution at 6 months follow-up. In cochleovestibular nerve hypoplasia, bilateral implantation could be discussed in cases of limited result after unilateral implant.

    Tibial hemimelia is a rare congenital limb deficiency which is characterised by a hypoplastic/aplastic tibia. It actually represents a spectrum of anomalies, ranging from mild hypoplasia of the tibia to total absence of the tibia. Several classifications based on radiological description exist in the literature. The tibial hemimelia is usually described with preaxial mirror polydactyly, split hand/foot syndrome-ectrodactyly, polydactyly-triphalangeal thumb syndrome (Werner syndrome) and micromelia-trigonal brachycephaly syndrome. We describe a child with unclassified tibial hemimelia. The child had right incomplete tibial hemimelia with bifid tibia, left complete tibial hemimelia, bilateral split hands and left split foot. This is the first report of the bifid tibia in the literature.

    Optic nerve hypoplasia is diagnosed by the ophthalmoscopic appearance of the fundus of the eye and by standard magnetic resonance imaging of the brain. The ability to study eyes with optic nerve hypoplasia by magnetic resonance diffusion tensor imaging has improved the evaluation of the optic pathways. The authors report a case of unilateral optic nerve hypoplasia with hypoplasia of the contralateral optic pathway. The entire visual pathway of this patient was examined by magnetic resonance and magnetic resonance diffusion tensor imaging. The images show a decrease of the volume of the optic radiation contralateral to the optic nerve abnormality and also pre- and post-chiasmal abnormalities.

  6. Blaschko Linear Enamel Defects – A Marker for Focal Dermal Hypoplasia: Case Report of Focal Dermal Hypoplasia

    PubMed Central

    Gysin, Stefan; Itin, Peter

    2015-01-01

    Focal dermal hypoplasia (FDH) is a rare genetic skin disorder. The inheritance of FDH or Goltz-Gorlin syndrome is X-linked dominant and the disease is associated with a PORCN gene mutation. This gene plays a key role in the Wnt pathway, which has an impact on embryonic development. Every tissue derived from meso- and ectoderm can be affected. Patients suffer from cutaneous, ocular, osseous, oral and dental defects. The skin and dental alterations manifest along the Blaschko lines. We present a woman (born in 1962) suffering from FDH with congenital skin changes and Blaschko linear enamel defects. Typical symptoms (e.g. fat herniations, scoliosis, syndactyly, microphthalmia, caries and alopecia) plus vertical grooving of all teeth gave a first indication. Molecular genetic testing confirmed the definitive diagnosis of FDH. We hypothesize that, in the context of typical skin changes, visible Blaschko lines on the teeth in the form of vertical grooves are almost pathognomonic for FDH. PMID:26078738

    2014-01-01

    A diaphragmatic hernia is defined as the protrusion of abdominal viscera into the thoracic cavity through a normal or pathological orifice. The herniated viscera compress the lungs, resulting in pulmonary hypoplasia and secondary pulmonary hypertension, which are the leading causes of neonatal death in patients with congenital diaphragmatic hernia. Congenital diaphragmatic hernia is diagnosed by sonography in routine prenatal screening. Although magnetic resonance imaging is fundamentally used to determine whether the liver is located within the abdomen or has herniated into the thorax, it also can provide useful information about other herniated structures and the degree of pulmonary hypoplasia. The aim of this article is to review the fetal magnetic resonance findings for congenital diaphragmatic hernia and the signs that enable us to establish the neonatal prognosis when evaluating pulmonary hypoplasia.

    Unraveling of the genetics of CAH offers the possibility of earlier detection and prenatal treatment or, alternatively, blastocyst embryo selection and eventually in utero gene therapy. Endocrine, surgical, and anesthesia management after birth have improved, leading to a better outcome for these patients. In the authors' experience, early one-stage reconstructive surgery, although demanding, allows one to use all available tissue. Once mastered, the repair is actually technically easier than vaginal pull-through surgery in the adolescent. Patients go through childhood with a body image that is more concordant with normal. Neither the child nor the parents must suffer the anticipation of a major operative intervention at puberty that can cause great emotional stress and that may be more difficult. The authors have encountered situations in late adolescence in which it has been impossible to separate the urogenital sinus from below. Under these circumstances, one can consider a posterior sagittal approach in which the rectum is bivalved to allow one to approach the vagina from below in an attempt to separate it safely from the urethra and to mobilize it to the perineum. It is also feasible to consider fashioning a segment of sigmoid colon as a neovagina, realizing that mucosal drainage needs to be managed daily. The authors have also encountered the rare 46,XX patient raised as a male and committed to the male role. In these cases, the patient can be offered gonadectomy, followed by staged complex hypospadias repair, and surgery to remove Müllerian structures and, if possible, to preserve the vas, followed by prepenile scrotal repair and insertion of testicular prostheses. Children with CAH require a lifetime of care with surgical approaches that are age appropriate. These patients can lead a full and productive life. It is the physician's responsibility to make certain that these children reach their full potential with the least number of interventions, which should be designed and optimized to produce the best possible outcome.

    2014-01-01

    Focal dermal hypoplasia (Goltz syndrome, Online Mendelian Inheritance in Man [OMIM] 305600) is a rare X-linked dominant congenital disorder involving defects of mesodermal- and ectodermal-derived structures. It is associated with mutations in the PORCN gene, a regulator of Wnt signaling proteins. The phenotype is highly variable, although all describe characteristic skin findings as a primary diagnostic feature. To date there are few case reports of focal dermal hypoplasia associated with central nervous system abnormalities. We report the second case of focal dermal hypoplasia associated with myelomenigocele, Arnold-Chiari malformation and hydrocephalus and the first in a male. Genetic testing identified a novel mosaic three base pair deletion within the PORCN gene (c.853_855delACG). This case highlights the importance of neurological evaluation in focal dermal hypoplasia and consideration of other syndromes more commonly associated with central nervous system abnormalities. In this report we summarize the literature on neurological manifestations in Goltz syndrome.

    Pontocerebellar hypoplasia is a group of severe developmental disorders with prenatal onset affecting the growth and function of the brainstem and cerebellum. The rarity and genetic heterogeneity of this group of disorders can make molecular diagnosis challenging. We report 3 siblings who were born to nonconsanguineous parents, were hypotonic at birth, developed seizures, had repeated apneic spells, and died within 2 months of life. Neuroimaging showed that all had profound cerebellar hypoplasia and simplified cortical gyration. Genetic analysis by whole-exome sequencing demonstrated compound heterozygous mutations in the mitochondrial arginyl transfer RNA synthetase gene RARS2, indicating that the children had pontocerebellar hypoplasia type 6. Autopsies on the younger twin siblings revealed small and immature cerebella at an approximate developmental age of less than 18 weeks. The basis pontis showed regressive changes, and the medulla had marked inferior olivary hypoplasia. The brains of both twins were microencephalic and had simplified gyri; cortices were immature, and deep white matter had extensive astrocytosis. The findings suggest a near-normal embryologic period followed by midgestation developmental slowing or cessation and later regression in select anatomic regions. This is the first detailed description of neuropathologic findings associated with pontocerebellar hypoplasia type 6 and demonstrates the profound effects of RARS2 disruption during early neurodevelopment.

    To report clinical characteristics of high grade foveal hypoplasia. Patients with foveal hypoplasia of grade 3 or 4 on spectral domain optical coherence tomography according to a previously published scheme were enrolled. All patients underwent a full ophthalmologic assessment including visual acuity testing, slit lamp biomicroscopy, fundus examination, and evaluation of ocular alignment. The underlying causes of foveal hypoplasia were identified as albinism in five patients and aniridia in six patients. The mean logMAR visual acuity was 0.57 ± 0.24 (range 0.22-1.00) in the right eyes and 0.58 ± 0.21 (range 0.30-1.00) in the left eyes. On fundus examination in patients with albinism, two patients showed marked transparency, one patient showed moderate transparency, and two patients showed minimal transparency. Among six patients with aniridia, five patients showed normal macular pigmentation without macular reflex and one patient showed decreased macular pigmentation with no macular reflex. Patients with high grade macular hypoplasia tended to have poor visual acuities; however, the range of visual acuity was quite variable. Other factors associated with underlying disease could be the reason of this variability. Therefore, careful consideration should be given when assessing visual prognosis in foveal hypoplasia using optical coherence tomography.

    The oromandibular limb hypogenesis syndromes (OLHS) represent a group of rare conditions characterized by congenital malformations involving the tongue, mandible, and limbs. There is considerable overlap between the syndromes gathered under the term OLHS, and a marked variability of face and limb anomalies as well as additional malformations. In this report we describe a girl with gastroschisis and pulmonary hypoplasia in addition to features of Moebius syndrome comprising hypoplasia of the tongue and mandible, brachydactyly of halluces, cranial nerve palsies with bilateral facial paralysis and an inability to execute horizontal eye movements. Karyotyping and array-based comparative genomic hybridization were normal. This observation confirms an overlap between Moebius syndrome and OLHS and widens the spectrum of associated malformations. Intrauterine environmental factors including vascular insufficiency, high maternal fever, and drug abuse are likely to play a crucial role in the pathogenesis of this condition.

    Adrenal imaging using radiopharmaceuticals is a functional test that can contribute significantly to surgical management and follow-up of patients with either benign or malignant conditions of the adrenal cortex and medulla. Imaging of the cortex is achieved by iodine-131-labeled iodomethyl nor-cholesterol (NP-59), while adrenal medulla imaging can be successfully accomplished by 131I-metaiodobenzylguanidine (MIBG), which localizes in the adrenergic nerve terminal with norepinephrine. Both tests carry high sensitivity and specificity for functional tumors and hyperplasia, and often better than CT scanning. This article reviews the current status and clinical utility of nuclear imaging of the adrenal cortex in congenital hyperplasia, low renin hypertension and aldosteronism, and Cushing's syndrome. Adrenal medulla imaging is reviewed in light of our experience at the University of Texas M.D. Anderson Cancer Center in pheochromocytoma, neuroblastoma, and other neuroectodermal tumors. Investigation of {sup 131}I-MIBG therapy of metastatic tumors of neuroectodermal origin potentially offers a means of at least controlling symptoms of hormonal secretion in these patients. 40 references.

  1. Dental enamel hypoplasias in prehistoric populations.

    PubMed

    Goodman, A H

    1989-09-01

    Recent years have witnessed an impressive increase in research on enamel hypoplasias in archaeological populations. By reviewing a series of studies of enamel hypoplasias at Dickson Mounds, Illinois, North America (950-1300 A.D.), a prehistoric site involved in the transition from gathering-hunting to agriculture, this paper provides an illustration of this type of research. The location of linear hypoplasias on labial tooth surfaces of 111 adults was studied with a thin-tipped caliper, and this location was converted to an age at development. Most defects developed between two and four years of developmental age. Hypoplasias increased in prevalence from 45% in the pre-agriculture group to 80% in the agricultural group (p less than 0.01). The transition to agriculture occurred at a cost to infant and childhood health. Defects are associated with decreased longevity. Individuals with defects have a life expectancy of nearly ten years fewer than those without defects, suggesting that the development of a defect marks a significant and lasting health event. Enamel hypoplasias occur most frequently on anterior teeth, polar teeth in developmental fields, and the middle developmental thirds of teeth. Analysis of these data suggests that enamel may be differentially susceptible to growth disruption and that susceptibility varies both within and among teeth. The study of enamel defects at Dickson provides insights into the health and nutritional consequences of the economic change from hunting and gathering to agriculture. More generally, with the availability of teeth from genetically homogeneous populations, studies of enamel hypoplasias in prehistory should provide a useful complement to research on this condition in contemporary peoples.

    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.

    Individuals with PHACE syndrome (posterior fossa malformations, hemangiomas, arterial anomalies, cardiac defects, eye abnormalities, sternal cleft, and supraumbilical raphe syndrome) have reported dental abnormalities to their healthcare providers and in online forums, but dental involvement has not been comprehensively studied. A study was conducted at the third PHACE Family Conference, held in Milwaukee, Wisconsin, in July 2012. A pediatric dentist examined subjects at enrollment. Eighteen subjects were enrolled. The median age was 4.2 years (range 9 mos-9 yrs; 14 girls, 4 boys). Eleven of 18 patients had intraoral hemangiomas and five of these (50%) had hypomature enamel hypoplasia. None of the seven patients without intraoral hemangiomas had enamel hypoplasia. No other dental abnormalities were seen. Enamel hypoplasia may be a feature of PHACE syndrome when an intraoral hemangioma is present. Enamel hypoplasia increases the risk of caries, and clinicians should refer children with PHACE syndrome to a pediatric dentist by 1 year of age.

    Two wild fledgling kestrels exhibited lack of motor coordination, postural reaction deficits, and abnormal propioception. At necropsy, the cerebellum and brainstem were markedly underdeveloped. Microscopically, there was Purkinje cells heterotopy, abnormal circuitry, and hypoplasia with defective foliation. Heterotopic neurons were identified as immature Purkinje cells by their size, location, immunoreactivity for calbindin D-28 K, and ultrastructural features. The authors suggest that this cerebellar abnormality was likely due to a disruption of molecular mechanisms that dictate Purkinje cell migration, placement, and maturation in early embryonic development. The etiology of this condition remains undetermined. Congenital central nervous system disorders have rarely been reported in birds.

    Adrenal schwannoma is an extremely uncommon cause of incidentaloma. It originates from neural sheath Schwann cells of the adrenal gland. We report the case of a left adrenal schwannoma incidentally discovered in a 32-year-old woman during examination of bloated feeling and stomach ache. The patient was incidentally found to have a left adrenal mass of 9 cm on abdominal ultrasonography. Computed tomography (CT) of the abdomen and [(18)F] fluorodeoxyglucose positron emission tomography (PET) were also performed. Metabolic evaluation was unremarkable. Due to the large size of the tumor, left adrenalectomy was performed. The postoperative course was uneventful. Histological examination established the diagnosis of schwannoma. This diagnosis was supported by immunohistochemistry of S-100 and vimentin positivity. In conclusion, adrenal schwannoma is an extremely rare entity and can grow considerably in size. The present case report emphasizes that clinicians should be aware of the possibility of retroperitoneal schwannoma. Total excision of benign schwannoma is associated with a favorable outcome. To our knowledge, there are case reports of schwannoma with CT and magnetic resonance imaging findings in the literature, although this is the first schwannoma case with PET-CT imaging.

The author established pathological deviations in 561 cases (11.8%). During further verification using scintigraphy unsuspected congenital renal abnormalities (aplasia, hypoplasia, dystopia, double kidney, horseshoe kidney, solitary cyst and polycystic renal disease) were found in 46 patients (8.2%). The diagnosis was confirmed at subsequent venous x-ray urography. A conclusion has been made as to the role of comprehensive nephrographic-scintigraphic examination in the diagnosis of congenital renal abnormalities.

    Blumenfeld, J D

    1993-03-01

    Abnormalities of adrenal cortical and medullary function are important causes of hypertension in adults. Mineralocorticoid hypertension, characterized by spontaneous hypokalemia with excessive kaliuresis and low plasma renin activity, is most commonly caused by aldosterone-producing adenoma or, less frequently, by nonadenomatous adrenal hyperplasia. However, recent evidence indicates that this classification oversimplifies the pathophysiologic diversity of this syndrome. Advances in steroid biochemistry and molecular biology have improved our ability to identify patients with various forms of mineralocorticoid hypertension and also provide evidence that they are underdiagnosed. Pheochromocytomas are most commonly located in the adrenal medulla, where they may overproduce norepinephrine or epinephrine. Appropriate screening of norepinephrine, epinephrine, and their metabolites is essential because tumors that secrete epinephrine exclusively may not present with hypertension and, thus, can be overlooked. Extra-adrenal pheochromocytomas are more prevalent than previously considered and pose special problems because they may be multicentric, difficult to locate, and more likely to be malignant than are adrenal pheochromocytomas.

    Anterior pituitary corticotrophin cells secrete ACTH as part of a larger precursor molecule, pro-opiomelanocortin. Post-translational cleavage of this precursor yields three major peptides: ACTH, beta-LPH and N-POMC. Experiments both in vivo and in vitro suggest that N-POMC may act as a prohormone amplifier for ACTH-induced adrenal steroidogenesis and as regulator of adrenocortical cell growth. The secretion of POMC is under the control of CRF. These findings are discussed in relation to the pathophysiology of corticotrophinoma. The primary defect in this condition appears to reside at the level of the anterior pituitary cell and is readily amenable to treatment by trans-sphenoidal microsurgery. The estimation of plasma ACTH concentrations is proving useful in the monitoring of various clinical conditions including Addison's disease and congenital adrenal hyperplasia.

    2015-08-01

    Antenatal diagnosis of lung lesion has become more accurate resulting in dilemma and controversies of its antenatal and postnatal management. Majority of antenatally diagnosed congenital lung lesions are asymptomatic in the neonatal age group. Large lung lesions cause respiratory compromise and inevitably require urgent investigations and surgery. The congenital lung lesion presenting with hydrops requires careful postnatal management of lung hypoplasia and persistent pulmonary hypertension. Preoperative stabilization with gentle ventilation with permissive hypercapnia and delayed surgery similar to congenital diaphragmatic hernia management has been shown to result in good outcome. The diagnostic investigations and surgical management of the asymptomatic lung lesions remain controversial. Postnatal management and outcome of congenital cystic lung lesions are discussed.

    Enamel defects, such as white or yellow-brown spots, usually cause problems that are more esthetic than functional. Enamel hypoplasia may be the result of hereditary, systemic, or local factors. Dental trauma is a local etiologic factor. It is relatively common in the primary dentition and can cause defects on the surface of permanent successors. Treatment for such defects can differ, depending on the depth of the spots. For deeper white-spot lesions, a composite resin restoration may be necessary. This is an excellent mode of treatment, due to both its low cost and its conservation of healthy tooth structure. The objective of this case report is to describe composite resin restoration of a maxillary central incisor affected by enamel hypoplasia.

    Pontocerebellar hypoplasia type 2 (PCH-2; MIM 277470), an autosomal recessive neurodegeneration with fetal onset, was studied in six autopsies with ages at death ranging between 1 and 22 years. Three patients were distantly related. A case of olivopontocerebellar hypoplasia (OPCH; MIM 225753) was studied for comparison. Typical findings are: short cerebellar folia with poor branching (“hypoplasia”), relative sparing of the vermis, sharply demarcated areas of full thickness loss of cerebellar cortex probably resulting from regression at an early stage of development, segmental loss of dentate nuclei with preserved islands and reactive changes, segmental loss in the inferior olivary nucleus with reactive changes, loss of ventral pontine nuclei with near absence of transverse pontine fibers and sparing of spinal anterior horn cells. Variable findings are: cystic cerebellar degeneration, found in two, with vascular changes limited to the cerebellum in one. Comparison to olivopontocerebellar hypoplasia (OPCH) strongly suggests a continuum of pathology between this disorder and PCH-2. Immunohistochemical evaluation of the endoplasmic reticulum stress response is negative. We conclude that the neuropathological findings in PCH-2 are sufficiently specific to enable an unequivocal diagnosis based on neuropathology. PMID:17641900

    Isolated Unilateral hypoplasia or agenesis of a branch of pulmonary artery is very rare. It is usually seen associated with congenital heart diseases such as tetralogy of Fallot, atrial septal defect, coarctation of the aorta, right aortic arch, truncus arteriosus, patent ductus arteriosus and pulmonary atresia. It occurs as a result of lack of embryological development of either the left or right sixth aortic arch and has been found to present itself with various clinical manifestations as during childhood it presents as contralateral pulmonary hypertension and in adults as haemoptysis. Early diagnosis and early surgical indication avoids the evolution of pulmonary hypertension to unfavourble state of more severe and progressive degrees and also prevents the development of pulmonary systemic collateral circulation, which is mainly responsible for subsequent haemoptysis in the adulthood. We hereby, report the case of an infant who presented with features of lower respiratory tract infection and later diagnosed as isolated congenital hypoplasia of left pulmonary artery and hence planned for proper follow-up for early surgery thereby preventing complications in the future.

    Foveal hypoplasia, always accompanied by nystagmus, is found as part of the clinical spectrum of various eye disorders such as aniridia, albinism and achromatopsia. However, the molecular basis of isolated autosomal recessive foveal hypoplasia is yet unknown. Individuals of apparently unrelated non consanguineous Israeli families of Jewish Indian (Mumbai) ancestry presented with isolated foveal hypoplasia associated with congenital nystagmus and reduced visual acuity. Genome-wide homozygosity mapping followed by fine mapping defined a 830 Kb disease-associated locus (LOD score 3.5). Whole-exome sequencing identified a single missense mutation in the homozygosity region: c.95T>G, p.(Ile32Ser), in a conserved amino acid within the first predicted transmembrane domain of SLC38A8. The mutation fully segregated with the disease-associated phenotype, demonstrating an ∼10% carrier rate in Mumbai Jews. SLC38A8 encodes a putative sodium-dependent amino-acid/proton antiporter, which we showed to be expressed solely in the eye. Thus, a homozygous SLC38A8 mutation likely underlies isolated foveal hypoplasia.

    We describe an unusual case of unilateral optic nerve hypoplasia (ONH) in a patient with contralateral anisometropic/strabismic amblyopia. A seven-year-old boy presented with visual acuities of 6/12 R and 6/18 L and eccentric fixation in the left eye. Cycloplegic retinoscopy was R +1.50/-0.50 × 180 and L +5.25 DS. Funduscopy revealed optic nerve hypoplasia of the right eye. The patient fixated with his better-seeing right eye, despite the optic nerve hypoplasia. His reduced vision may be attributed to optic nerve hypoplasia in the right eye and amblyopia in the left. Although optic nerve hypoplasia can occur with ipsilateral amblyopia, we believe this is the first reported case of unilateral optic nerve hypoplasia in the fellow eye of an amblyopic patient.

    An adrenal mass can be either symptomatic or asymptomatic in the form of adrenal incidentalomas (AIs) in up to 8 % in autopsy and 4 % in imaging series. Once a diagnosis of adrenal mass is made, we need to differentiate whether it is functioning or nonfunctioning, benign, or malignant. In this article, we provide a literature review of the diagnostic workup including biochemical evaluation and imaging characteristics of the different pathologies. We also discuss the surgical strategies with laparoscopy as the mainstay with partial adrenalectomy in select cases and adrenalectomy in large masses. Follow-up protocol of AIs and adrenocortical carcinoma is also discussed.

    Horseshoe lung, a rare congenital anomaly, is almost always associated with unilateral (usually right-sided) lung hypoplasia, and, in most cases, in conjunction with the scimitar syndrome. We present an 8-month-old boy with horseshoe lung associated with left-lung hypoplasia, left pulmonary artery sling and bilateral agenesis of the upper lobe bronchi, diagnosed by multidetector CT (MDCT) imaging. The study also revealed an anomalous origin of the left vertebral artery as the last branch of the aortic arch, distal to the left subclavian artery, and an anomalous origin of the left common carotid artery from the brachiocephalic trunk. A hemivertebral anomaly of the seventh cervical vertebra was incidentally detected. MDCT with high-quality multiplanar and three-dimensional reconstructions is a noninvasive and rapid technique for detecting the complex combination of vascular, tracheobronchial and parenchymal anomalies, and any potential bone anomalies, in one imaging study.

  7. Mass spectrometry theory and application to adrenal diseases.

    PubMed

    Wooding, Kerry M; Auchus, Richard J

    2013-05-22

    The diagnosis and management of adrenal diseases hinge upon accurate determination of hormone concentrations in blood and other body fluids. The advent of immunoassays for various steroid hormones has enabled the remarkable progress in adrenal disease over the last several decades, with some limitation. Sequential immunoassay of single analytes is a tedious process, which requires aliquots for each assay. In many complex adrenal diseases, including adrenal cancer and congenital adrenal hyperplasia, the patterns or ratios of multiple steroids rather than the value of any one steroid is more relevant. Although gas chromatography/mass spectrometry of urinary steroid metabolites has been employed to profile steroid production, throughput is slow, and availability is sparse. Recent generations of liquid chromatography-tandem mass spectrometry instruments (LC-MS/MS) provide the throughput and sensitivity required to measure many steroids simultaneously using small samples for commercial and research uses. Even in the best hands, however, LC-MS/MS suffers from limitations and requires diligent attention to detail during method development and implementation. This article reviews the theory, instrumentation principles and terminology, and practical application of mass spectrometry to clinical adrenal disorders.

  8. Ontogeny of adrenal steroid biosynthesis: why girls will be girls

    PubMed Central

    White, Perrin C.

    2006-01-01

    Male and female external genitalia appear identical early in gestation. Testosterone exposure at 8–12 weeks’ gestation causes male differentiation. Female fetuses virilize if their adrenals secrete excessive levels of androgens, as occurs in congenital adrenal hyperplasia due to 21-hydroxylase deficiency. This can be ameliorated by administering dexamethasone to the mother. A study by Goto et al. in this issue of the JCI provides a rationale for this treatment by demonstrating that the fetal hypothalamic-pituitary-adrenal axis is fully functional when the genitalia differentiate (see the related article beginning on page 953). Dexamethasone suppresses this axis, reducing abnormal secretion of adrenal androgens. Their results also show that cortisol synthesis by the fetal adrenal decreases after this period, allowing the adrenal to secrete high levels of dehydroepiandrosterone, an androgen precursor. However, this does not virilize female fetuses because androgens are aromatized to estrogens in the placenta. Thus normal sexual differentiation requires exquisite timing of fetal cortisol and androgen secretion versus placental capacity for aromatization. PMID:16585958

    Hypoplasia, or glandular insufficiency, of the breasts is an infrequent cause of breastfeeding failure or infant failure to thrive. Early evaluation of the breasts of early identification of infant indicators can enable mothers to breastfeed while providing appropriate supplementation to facilitate satisfactory hydration and growth. A case report is presented of a highly motivated mother with minimal breast tissue who was able to soothe four of her infants at her breasts, supplying some breastmilk, while providing the bulk of their nutritional requirements by other means. At the time of writing she is tandem breastfeeding as well as providing artificial milk by bottle.

  10. Chest wall hypoplasia--principles and treatment.

    2015-01-01

    The chest is a dynamic structure. For normal movement it relies on a coordinated movement of the multiple bones, joints and muscles of the respiratory system. While muscle weakness can have clear impact on respiration by decreasing respiratory motion, so can conditions that cause chest wall hypoplasia and produce an immobile chest wall. These conditions, such as Jarcho-Levin and Jeune syndrome, present significantly different challenges than those faced with early onset scoliosis in which chest wall mechanics and thoracic volume may be much closer to normal. Because of this difference more aggressive approaches to clinical and surgical management are necessary.

    Two hundred black and white adult human skeletons and 200 living black and white children from the greater Cleveland area were examined for evidence of enamel hypoplasia. Enamel hypoplasia, present in varying expressings (pits, lines and grooves), was found to be more prevalent in both skeletal samples, than in the living groups. In the majority of cases, sex differences between white and black males and females through time and space are highly significant for all tooth catagories. Regardless of the mechanisms behind it, prevalence of enamel hypoplasia for both white and black group has significantly declined through time. No evidence suggesting specific etiologies responsible for enamel hypoplasia can be found. In the majority of previously published reports, the etiology is still idiopathic. The reduction in the prevalence of enamel hypoplasia in the groups examined through time may be related to improved nutritional conditions and the elimination or decline of childhood diseases that have been implicated in this condition.

    2013-09-01

    This special article aims to summarise the current knowledge regarding the two groups of tumours with their origin in the adrenal gland: 1) adrenocortical tumours, derived from the cortex of the adrenal gland and 2) phaeochromocytomas and paragangliomas, neuroendocrine tumours derived from nodes of neural crest derived cells symmetrically distributed at both sides of the entire spine (paragangliomas [PG]). These PGs can be functioning tumors that secrete catecholamines, which confers their typical dark colour after staining with chromium salts (chromaffin tumors). Among these, the term phaeochromocytoma (PC) is restricted to those PGs derived from the chromaffin cells in the adrenal medulla (intra-adrenal PGs), whereas the term PG is used for those sympathetic or parasympathetic ones in an extra-adrenal location. We analyse the state of the art of their pathogenic and genetic bases, as well as their clinical signs and symptoms, the tests currently available for performing their diagnosis (biochemical, hormonal, imaging and molecular studies) and management (surgery, pre- and post-surgical medical treatment), considering the current and developing strategies in chemo- and radiotherapy.

    Objective: Review the impact of StAR (STARD1) mutations on steroidogenesis and fertility in LCAH patients. Examine the endocrine mechanisms underlying the pathology of the disorder and the appropriate therapy for promoting fertility and pregnancies. Design: Published data in the literature and a detailed 38-year follow-up of two sibling LCAH patients. Molecular structure and modeling of the STARD1 L275P mutation. Setting: University hospital. Patients: Patient A (46,XY female phenotype) and patient B (46,XX female) with LCAH bearing the L275P mutation in STARD1. Interventions: Since early-age diagnosis, both patients underwent corticoid replacement therapy. Patient A received estrogen therapy at pubertal age. Clomiphene therapy was given to Patient B to induce ovulation. Pregnancies were protected with progesterone administration. Main Outcome Measures: Clinical and molecular assessment of adrenal and gonadal functions. Results: Both patients have classic manifestations of corticosteroid deficiency observed in LCAH. Time of onset and severity were different. Patient A developed into a female phenotype due to early and severe damage of Leydig cells. Patient B started a progressive pubertal development, menarche and regular non-ovulatory cycle. She was able to have successful pregnancies. Conclusions: Understanding the molecular structure and function of STARD1 in all steroidogenic tissues is the key for comprehending the heterogeneous clinical manifestations of LCAH, and the development of an appropriate strategy for the induction of ovulation and protecting pregnancies in this disease.

    Adrenal tumors comprise a broad spectrum of benign and malignant neoplasms and include functional adrenal adenomas, pheochromocytomas, primary adrenocortical carcinoma, and adrenal metastases. Percutaneous ablative approaches that have been described and used in the treatment of adrenal tumors include percutaneous radiofrequency ablation, cryoablation, microwave ablation, and chemical ablation. Local tumor ablation in the adrenal gland presents unique challenges, secondary to the adrenal gland's unique anatomic and physiological features. The results of clinical series employing percutaneous ablative techniques in the treatment of adrenal tumors are reviewed in this article. Clinical and technical considerations unique to ablation in the adrenal gland are presented, including approaches commonly used in our practices, and risks and potential complications are discussed.

This syndrome comprises: short stature due to a marked decrease in the length of the lower limbs (predominantly mesomelic with fibular agenesis/marked hypoplasia), grossly malformed/deformed clubfeet with severe oligodactyly, upper limbs with acromial dimples and variable motion limitation of the forearms and/or hands, severe nail hypoplasia/anonychia sometimes associated with mild brachydactyly and occasionally with pre-axial polydactyly. This syndrome is apparently distinct from the syndrome of brachydactyly-ectrodactyly with fibular aplasia or hypoplasia (OMIM 113310), the syndrome of fibular aplasia or hypoplasia, femoral bowing and poly-, syn-, and oligodactyly (OMIM 228930), and from other previously described conditions exhibiting fibular agenesis/hypoplasia.

  2. The rat adrenal medulla.

    PubMed

    Tischler, A S

    1989-01-01

    Adult adrenal medullary cells, in many strains of rats, develop diffuse and nodular hyperplasia and neoplasia under a variety of conditions. Both endogenous and exogenous factors affect the development of these proliferative changes. The former include the animals' strain, age, and sex. The latter include drugs and other environmental agents, diet, and perhaps stress. Adrenal medullary neoplasms which arise under diverse circumstances often closely resemble each other both morphologically and functionally, and exhibit characteristics of immature chromaffin cells. Recent data indicate that normal, mature-appearing epinephrine- and norepinephrine-type chromaffin cells are able to divide, and suggest that signals which regulate chromaffin cell function also regulate cell proliferation. Prolongation of these signals or superimposed abnormalities might initiate pathological proliferative states. It remains to be determined whether the mechanisms which promote or prevent cell proliferation in the adult adrenal are related to those involved in normal development.

    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.

    Ectopia cordis, defined as partial or complete displacement of the heart outside of the thoracic cavity, is a rare congenital malformation. If not surgically corrected during the early years of life, ectopia cordis can prove to be a fatal abnormality. However, due to the presence of multiple intracardiac and extracardiac malformations, a corrective surgery might not always be successful. The pathology of ectopia cordis with a double outlet right ventricle, large ventricular septal defect, malposed great arteries and left ventricular hypoplasia is discussed, highlighting the complexities involved in such a rare disorder.

    2016-09-01

    Congenital hemangiomas are rare solitary vascular tumors that do not proliferate after birth. They are characterized as either rapidly involuting congenital hemangiomas (RICHs) or noninvoluting congenital hemangiomas (NICHs) based on their clinical progression. NICHs have no associated complications, but are persistent. RICH, while usually asymptomatic, may ulcerate or bleed early in their presentation, but involute quickly during the first few months of life. Hepatic RICHs are not associated with cutaneous RICHs, but may result in high-output cardiac failure due to arteriovenous or portovenous shunting. In the following review, the clinical characteristics and current management specific to congenital hemangiomas is discussed.

    Acrocallosal Syndrome is a rare genetic disorder which is characterized by moderate to severe mental retardation, agenesis or hypoplasia of the corpus callosum and polydactyly of fingers and toes. The spectrum of this syndrome is very variable. Prominent forehead, broad nasal bridge, short nose and mandible, hypertelorism, epicanthic folds, large anterior fontanelle and tapered fingers, omphalocele and inguinal hernia are some other common findings in this syndrome. Twenty percent of the patients have associated brain abnormalities such as cerebral atrophy, hypothalamic dysfunction, small cerebrum, micropolygyria, hypoplasia of pons, hypoplasia of cerebellar hemispheres, hypoplasia of medulla oblongata, agenesis or hypoplasia of cerebellar vermis and corpus callosum abnormalities. Here we present a 10-month-old female infant with clinical and radiological findings indicative of acrocallosal syndrome. She was noted to have craniofacial abnormalities suggestive of acrocallosal syndrome, optic atrophy and polydactyly. MRI revealed cerebral atrophy, corpus callosum agenesis, dilated lateral ventricules and unilateral right temporal lobe hypoplasia, the latter not previously reported in the spectrum of this syndrome. Based on this observation we conclude the importance of screening brain abnormalities and present temporal lobe hypoplasia as a new additional anomaly in this syndrome.

  9. Portal hypertension associated with primary hypoplasia of the hepatic portal vein in dogs.

    PubMed

    Van den Ingh, T S; Rothuizen, J; Meyer, H P

    1995-10-21

    Portal hypertension caused by primary hypoplasia of the portal vein was diagnosed in 42 dogs. The portal hypertension was manifested by the presence of multiple portosystemic collateral vessels. The main clinical signs were retarded growth or weight loss, apathy, intermittent diarrhoea and vomiting, anorexia, abdominal distension and polydipsia. Major findings at physical examination were ascites in 23 dogs and neurological signs in 16 dogs. The dogs had increased activities of liver enzymes in plasma and increased fasting levels of total bile acids and ammonia; in many of the dogs the packed red cell volume, total serum protein and albumin were low. Gross inspection of the portal vein revealed a patent but underdeveloped extrahepatic vein in 13 of the dogs. Microscopic examination of the liver revealed hypoplasia of the intrahepatic portal veins in all the dogs, and this was associated with minor arteriolar proliferation and absence of fibrosis in 12 of them, with moderate to marked arteriolar proliferation often combined with ductular proliferation in 13, and with marked portal fibrosis (formerly described as hepatoportal fibrosis) with a varying number of arteriolar and bile ductular structures in 17 of the dogs. The disease affected mainly young dogs, and was most likely to have been of congenital origin.

  10. Soft palate hypoplasia and concurrent middle ear pathology in six dogs.

    This retrospective clinical study describes six consecutive cases of bilateral hypoplasia/malformation of the soft palate in dogs in which associated middle ear disease was investigated and the palatine defects were surgical repaired. Radiographic abnormalities of the tympanic bullae were seen in both ears of all six dogs (12 of 12). Negative tympanocentesis findings were recorded in 11 of 12 ears. A purulent otitis media was confirmed in one ear of one dog, and loss of hearing was also demonstrated in this ear on brainstem auditory evoked response hearing assessment. There was no evidence of hearing loss on brainstem auditory evoked response in any of the remaining ears. Surgical repair of the soft palate defect was undertaken in all six dogs. Long-term assessment of the clinical outcome was considered excellent in five dogs and reasonable in one dog (mean 18 months, range seven to 27 months). It would appear that surgical intervention for the treatment of bilateral palatine malformation/hypoplasia may be associated with a better prognosis than reported previously. The lack of middle ear effusion and associated hearing impairment suggests that the underlying aetiology of middle ear pathology in dogs suffering from congenital palatine defects may be different from that observed in human beings. The true nature of the radiographic bullae changes seen in dogs with soft palate defects remains unclear.

    Maxillary sinus aplasia and hypoplasia are rare conditions that can cause symptoms such as headaches and voice alteration. The majority of patients are asymptomatic, but these conditions must be noticed for importance of differential diagnosis such as infection and neoplasms. Conventional radiographs could not differentiate between inflammatory mucosal thickening, neoplasm, and hypoplasia of the sinus. Computed tomography (CT) and also cone beam computed tomography (CBCT) are the proper modalities to detect these conditions. In the present study, CBCT findings of three cases with maxillary sinus hypoplasia and aplasia are reported. PMID:25426156

    Three patients (two of them siblings) had Leber's congenital amaurosis and cerebellar disease. Despite blindness and severe motor deficits, all three patients have achieved relatively normal intellectual and psychosocial milestones. Computed tomographic scans, performed in two patients, demonstrated hypoplasia of the cerebellar vermis in both. The presence of delayed speech and motor development as well as structural CNS abnormalities in children with Leber's congenital amaurosis does not necessarily imply that severe intellectual impairment will be present.

    We report on a 22 years old lady with aplasia of uterus and most of the vagina with normal secondary sexual characteristics, unilateral renal hypoplasia and anomalies of cervico throacic somites (MURCS Association), growth retardation, cardiac defect and congenital urethrovaginal fistula. Although there is a broad spectrum of anomalies described with MURCS association genitourinary fistula is not yet reported and reviewed in published articles. The relevance of this paper is to show the importance of further investigation in cases of primary amenorrhoea with mullerian agenesis to establish that the patient has MURCS association and not simply MRKH (Mayer Rokitansky-Kusterhauser Syndrome) syndrome. Consequently we should provide guidance to the patients and their families about the best way to conduct the case including genetic counseling and family screening.

    Brachyphalangy, polydactyly and tibial aplasia/hypoplasia syndrome (OMIM 609945) is a rare congenital disorder. Only seven patients have been reported to date, and the etiology of this syndrome is unknown. Autosomal dominant inheritance with variable expression has been suggested based on the presence of minor features in some parents and the fact that neither parental consanguinity nor pairs of affected siblings were observed. We report on the first patient with this syndrome who was born to consanguineous parents. Neither the mother nor the father, who were first cousins, had clinical features suggestive of a manifestation of brachyphalangy, polydactyly and tibial aplasia/hypoplasia syndrome. The patient had no siblings, and the family history was unremarkable. Clinical problems included brachydactyly of hands and feet, splaying of fingers and toes, preaxial polydactyly of feet, bilateral tibial aplasia, shortened radius and ulna, and characteristic facial dysmorphic signs. The detailed description of this patient adds to our knowledge of the clinical manifestations of brachyphalangy, polydactyly and tibial aplasia/hypoplasia syndrome and will eventually also contribute to the elucidation of the underlying gene defects.

    Pulmonary hypoplasia is characterized by decrease in the number and size of pulmonary airways, alveoli and vessels. In autopsy, pulmonary hypoplasia is a major cause of death in neonates and infants. The disease is usually diagnosed in childhood period. Although it mimics lung parenchymal disease and other vascular abnormalities radiologically, it is easily recognized with computed tomography angiography and magnetic resonance angiography examinations. In 50% of patients, concomitant cardiovascular, neuromuscular, gastrointestinal tract, and urogenital anomalies are also available. There are two types of pulmonary hypoplasia: primary and secondary. Primary unilateral pulmonary hypoplasia may be asymptomatic and the tendency for bronchopulmonary infections is often increased in children. In this case report, a 22-month-old male patient characterized by recurrent infections and recurrent wheezes in infantile period, whose episodes of wheezing regressed after the pulmonectomy, was presented.

    Abstract Rationale: Hypoplasia with an intact posterior arch of the atlas and ossification of the posterior atlantoaxial membrane (PAAM) are individually rare. Patient concerns: The patient presented with a 6-month history of progressive weakness and paresthesia of his lower extremities. Diagnoses: Cervical myelopathy resulting from atlas hypoplasia and ossification of the posterior atlantoaxial membrane. Interventions: Laminectomy of the atlas with duroplasty. Outcomes: Preoperative symptoms were alleviated. Lessons: In most reported cases, either atlas hypoplasia or ossification of the PAAM is responsible for patients’ myelopathy. The case illustrated here, to the best of our knowledge, is the first one with coexistent atlas hypoplasia and ossification of the PAAM. And laminectomy of the atlas with duroplasty provided satisfied outcome. PMID:27902623

  20. Congenital Diaphragmatic Hernia

    PubMed Central

    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

    1995-03-01

    The prevalence and chronology of enamel hypoplasias were studied in a hominid dental sample from the Sima de los Huesos (SH) Middle Pleistocene site at the Sierra de Atapuerca (Burgos, northern Spain). A total of 89 permanent maxillary teeth, 143 permanent mandibular teeth, and one deciduous lower canine, belonging to a minimum of 29 individuals, were examined. Excluding the antimeres (16 maxillary and 37 mandibular cases) from the sample, the prevalence of hypoplasias in the permanent dentition is 12.8% (23/179), whereas the deciduous tooth also showed an enamel defect. No statistically significant differences were found between both arcades and between the anterior and postcanine teeth for the prevalence of hypoplasias. In both the maxilla and the mandible the highest frequency of enamel hypoplasias was recorded in the canines. Only one tooth (a permanent upper canine) showed two different enamel defects, and most of the hypoplasias were expressed as faint linear horizontal defects. Taking into account the limitations that the incompleteness of virtually all permanent dentitions imposes, we have estimated that the frequency by individual in the SH hominid sample was not greater than 40%. Most of the hypoplasias occurred between birth and 7 years (N = 18, X = 3.5, SD = 1.3). Both the prevalence and severity of the hypoplasias of the SH hominid sample are significantly less than those of a large Neandertal sample. Furthermore, prehistoric hunter-gatherers and historic agricultural and industrial populations exhibit a prevalence of hypoplasias generally higher than that of the SH hominids. Implications for the survival strategies and life quality of the SH hominids are also discussed.

  2. Adrenal cortical and medullary imaging.

    Freitas, J E

    1995-07-01

    Adrenal disease can be manifested by endocrine dysfunction or anatomic abnormalities detected by cross-sectional imaging modalities. With the advent of newer and more reliable in vitro assays and a better understanding of the spectrum of adrenal pathology, the physician can now adopt a more accurate and cost-effective approach to the diagnosis of adrenal disease. Both functional and anatomic imaging modalities can play an important role in the evaluation of the incidental adrenal mass, the early detection of adrenal metastases, differentiation of the various causes of Cushings's syndrome, selection of patients for potentially curative surgery in primary aldosteronism and adrenal hyperandrogenism, and localization of pheochromocytomas and neuroblastomas. The usefulness of the adrenal cortical radiopharmaceutical, 131I-6-beta-iodomethylnorcholesterol (NP-59), and the adrenal medullary radiopharmaceuticals, 131I and 123I-metaiodobenzylguanidine (MIBG), is detailed for these various clinical settings and the role of NP-59 and MIBG is contrasted to that of the cross-sectional modalities, computed tomography and magnetic resonance imaging (MRI). Incidental adrenal masses are common, but malignancies are few. Imaging studies select those patients who require a further evaluation by biopsy examination or adrenalectomy. In the hyperfunctioning endocrine states, such as Cushing's syndrome, primary aldosteronism, adrenal androgenism, and pheochromocytoma, correlation of biochemical findings with both functional and anatomic imaging is necessary to avoid inappropriate and ineffective surgical intervention, yet not miss an opportunity for curative resection. Lastly, MIBG and MRI are complementary in the detection and staging of neuroblastoma.

    Enamel hypoplasia is a surface defect of the tooth crown caused by a disturbance of enamel matrix secretion. Enamel hypoplasia may be inherited, or result from illness, malnutrition, trauma, or high concentrations of fluorides or strontium in the drinking water or food. Different types of enamel hypoplasia have been distinguished, such as pit-type, plane-type, and linear enamel hypoplasia. Hypoplasia has been related to the intensity and duration of stress events, the number of affected ameloblasts, and their position along the forming tooth crown. Amelogenesis imperfecta (AI) is a heterogeneous group of inherited defects in dental enamel formation, most teeth are affected in both the primary and permanent dentition. The malformed enamel can be unusually thin, soft, rough and stained. The strict definition of AI includes only those cases where enamel defects occur in the absence of other symptoms. Currently, there are seven candidate genes for AI: amelogenin, enamelin, ameloblastin, tuftelin, distal-less homeobox 3, enamelysin, and kallikrein 4. Since the enamel is formed according to a strict chronological sequence, and once formed, undergoes no repair or regeneration. Then the analysis the phenotype of enamel hypoplasia can provide insights of the severity of inherited or environmental stress and the molecular mechanism during the period of enamel formation.

  4. Mammary hypoplasia: not every breast can produce sufficient milk.

    PubMed

    2013-01-01

    Breast milk is considered the optimal form of nutrition for newborn infants. Current recommendations are to breastfeed for 6 months. Not all women are able to breastfeed. Mammary hypoplasia is a primary cause of failed lactogenesis II, whereby the mother is unable to produce an adequate milk volume. Women with mammary hypoplasia often have normal hormone levels and innervation but lack sufficient glandular tissue to produce an adequate milk supply to sustain their infant. The etiology of this rare condition is unclear, although there are theories that refer to genetic predisposition and estrogenic environmental exposures in select agricultural environments. Women with mammary hypoplasia may not exhibit the typical breast changes associated with pregnancy and may fail to lactate postpartum. Breasts of women with mammary hypoplasia may be widely spaced (1.5 inches or greater), asymmetric, or tuberous in nature. Awareness of the history and clinical signs of mammary hypoplasia during the prenatal period and immediate postpartum increases the likelihood that women will receive the needed education and physical and emotional support and encouragement. Several medications and herbs demonstrate some efficacy in increasing breast milk production in women with mammary hypoplasia.

The tracheo-or-bronchobiliary fistula is a communication between the respiratory (trachea or bronchus) and biliary tract. To date, only 35 cases have been published worldwide. We report a case of a neonate with right pneumonia and bilious fluid in the endotracheal tube. Diagnosis was made using bronchoscopy with fluoroscopy. Videothoracoscopy was used to remove the bronchobiliary fistula. Subsequently, a left he-patectomy with Roux-en-Y biliary-digestive anastomosis was performed as bile ductus hypoplasia was present.

    Thirty-one patients had Leber's congenital amaurosis. Only one was severely retarded, and three demonstrated hypoplasia of the cerebellar vermis on computed tomographic scanning. These findings are in contrast to those of previous investigators, who have emphasized the high incidence of psychomotor retardation associated with Leber's amaurosis. Much of the psychomotor retardation that has been reported is probably secondary to the sensory deprivation and not necessarily a sign of structural CNS dysfunction. The diagnosis of Leber's congenital amaurosis does not, therefore, portend severe intellectual impairment and poor educability.

A 27 year old woman married to her first cousin was counseled for anophthalmia and cleft lip and palate detected during routine fetal ultrasonographic examination on the 23rd week of the pregnancy. Her obstetric history revealed a healthy girl aged 7 years and a boy with anophthalmia and cleft lip and palate who lived for 20 days in the neonatal intensive care unit. The current pregnancy was terminated after the diagnosis, and post mortem examination of the fetus revealed pre-maxilla agenesis, anophthalmia, cerebral ventricular dilatation, adrenal hypoplasia and single umbilical artery. Chromosome analysis resulted in normal karyotypes of the fetus and both parents. The inheritance pattern was regarded as autosomal recessive and the family was informed about the condition and risks during genetic counseling.

    Bilateral adrenal hemorrhage with subsequent adrenal insufficiency is a recognized complication of anticoagulant therapy. Because the clinical manifestations are often nonspecific, the antemortem diagnosis of adrenal hemorrhage has been a difficult clinical problem. Computed tomography (CT) provides detailed images of the adrenal glands that are not possible with conventional imaging methods. The CT findings of bilateral adrenal hemorrhage in an anticoagulated patient are reported.

    Abstract The laparoscopic adrenalectomy is considered as the procedure of choice for the treatment of adrenal hyperplasia and tumor lesions. However, some special situations may limit the use of this method due to the difficulty to locate the gland and perform the lesion excision. We analyze 2 patients of a left adrenal tumor, explaining how they have overcome the difficulties in both situations. The first case was a patient with a history of intra-abdominal surgery and the other patient suffered from severe obesity. We performed with the use of the gamma probe, and the 2 cases, was of great help to access and glandular localization. The help of gamma probe test was achieved in the surgical bed, that removal was complete. The use of the portable gamma probe facilitated the access to the left adrenal gland as well as conducting the glandular excision without delay, despite the difficulties due to the intra abdominal surgery caused by the previous surgery, and in the case of severe obesity.

    The classification of posterior fossa congenital anomalies has been a controversial topic. Advances in genetics and imaging have allowed a better understanding of the embryologic development of these abnormalities. A new classification schema correlates the embryologic, morphologic, and genetic bases of these anomalies in order to better distinguish and describe them. Although they provide a better understanding of the clinical aspects and genetics of these disorders, it is crucial for the radiologist to be able to diagnose the congenital posterior fossa anomalies based on their morphology, since neuroimaging is usually the initial step when these disorders are suspected. We divide the most common posterior fossa congenital anomalies into two groups: 1) hindbrain malformations, including diseases with cerebellar or vermian agenesis, aplasia or hypoplasia and cystic posterior fossa anomalies; and 2) cranial vault malformations. In addition, we will review the embryologic development of the posterior fossa and, from the perspective of embryonic development, will describe the imaging appearance of congenital posterior fossa anomalies. Knowledge of the developmental bases of these malformations facilitates detection of the morphological changes identified on imaging, allowing accurate differentiation and diagnosis of congenital posterior fossa anomalies.

    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.

    The human adult adrenal cortex is composed of the zona glomerulosa (zG), zona fasciculata (zF), and zona reticularis (zR), which are responsible for production of mineralocorticoids, glucocorticoids, and adrenal androgens, respectively. The final completion of cortical zonation in humans does not occur until puberty with the establishment of the zR and its production of adrenal androgens; a process called adrenarche. The maintenance of the adrenal cortex involves the centripetal displacement and differentiation of peripheral Sonic hedgehog-positive progenitors cells into zG cells that later transition to zF cells and subsequently zR cells.

  18. Adrenal crisis secondary to bilateral adrenal haemorrhage after hemicolectomy

    PubMed Central

    Tsang, Venessa H M; Kabir, Shahrir; Ip, Julian C Y

    2016-01-01

    Summary Adrenal haemorrhage is a rare cause of adrenal crisis, which requires rapid diagnosis, prompt initiation of parenteral hydrocortisone and haemodynamic monitoring to avoid hypotensive crises. We herein describe a case of bilateral adrenal haemorrhage after hemicolectomy in a 93-year-old female with high-grade colonic adenocarcinoma. This patient’s post-operative recovery was complicated by an acute hypotensive episode, hypoglycaemia and syncope, and subsequent computed tomography (CT) scan of the abdomen revealed bilateral adrenal haemorrhage. Given her labile blood pressure, intravenous hydrocortisone was commenced with rapid improvement of blood pressure, which had incompletely responded with fluids. A provisional diagnosis of hypocortisolism was made. Initial heparin-induced thrombocytopenic screen (HITTS) was positive, but platelet count and coagulation profile were both normal. The patient suffered a concurrent transient ischaemic attack with no neurological deficits. She was discharged on a reducing dose of oral steroids with normal serum cortisol levels at the time of discharge. She and her family were educated about lifelong steroids and the use of parenteral steroids should a hypoadrenal crisis eventuate. Learning points: Adrenal haemorrhage is a rare cause of hypoadrenalism, and thus requires prompt diagnosis and management to prevent death from primary adrenocortical insufficiency. Mechanisms of adrenal haemorrhage include reduced adrenal vascular bed capillary resistance, adrenal vein thrombosis, catecholamine-related increased adrenal blood flow and adrenal vein spasm. Standard diagnostic assessment is a non-contrast CT abdomen. Intravenous hydrocortisone and intravenous substitution of fluids are the initial management. A formal diagnosis of primary adrenal insufficiency should never delay treatment, but should be made afterwards. PMID:27855238

    Congenital diarrhoea of heterogenic etiology is a rare cause of chronic diarrhoea. Characteristic features are: onset in the first weeks of life, life-threatening severe dehydratation and electrolyte disorders leading to a necessity of long-term parenteral nutrition. The clinical onset may be delayed and the degree of diarrhoea may be modest, making the diagnosis difficult. The main causes of congenital diarrhoea such as intestine electrolytes, carbohydrates, lipid and protein transport disorders and congenital enzymatic deficiencies, enterocyte polarization disorders, hormonal, immunological, metabolic, genetic and congenital anatomic disorders are presented in the paper. Some of them, such as: microvillus inclusion disease, tufting enteropathy, intestinal anedocrynosis, IPEX syndrome (immunodysregulation polyendocrinopathy enteropathy X-linked syndrome) have been described recently. One of the basic investigations, when congenital diarrhea is suspected, is general examination of the stool, its electrolyte concentration and serum electrolytes and blood gas analysis. Often, small bowel biopsy with histological examination (with the use of electronic microscopy and PAS staining) is indicated. In some cases molecular examination is possible and indicated. In differential diagnosis other, more frequent causes of chronic diarrhea of infancy, have to be excluded. In most of the cases of congenital diarrhoea there is no casual treatment available - usually long-term parenteral nutrition is necessary.

    Multiple traumatic and non-traumatic adrenal emergencies are occasionally encountered during the cross-sectional imaging of emergency department patients. Traumatic adrenal hematomas are markers of severe polytrauma, and can be easily overlooked due to multiple concomitant injuries. Patients with non-traumatic adrenal emergencies usually present to an emergency department with a non-specific clinical picture. The detection and management of adrenal emergencies is based on cross-sectional imaging. Adrenal hemorrhage, adrenal infection, or rupture of adrenal neoplasm require immediate detection to avoid dire consequences. More often however, adrenal emergencies are detected incidentally in patients being investigated for non-specific acute abdominal pain. A high index of suspicion is required for the establishment of timely diagnosis and to avert potentially life-threatening complications. We describe cross-sectional imaging findings in patients with traumatic and non-traumatic adrenal hemorrhage, adrenal infarctions, adrenal infections, and complications of adrenal masses.

  1. Congenital cardiovascular malformations and the fetal circulation.

    PubMed

    Rudolph, A M

    2010-03-01

    After birth, gas exchange is achieved in the lung, whereas prenatally it occurs in the placenta. This is associated with differences in blood flow patterns in the fetus as compared with the postnatal circulation. Congenital cardiovascular malformations are associated with haemodynamic changes in the fetus, which differ from those occurring postnatally. Obstruction to cardiac outflow may alter myocardial development, resulting in progressive ventricular hypoplasia. Alteration of oxygen content may profoundly influence pulmonary vascular and ductus arteriosus responses. Interference in blood flow and oxygen content may affect cerebral development as a result of inadequate oxygen or energy substrate supply. The circulatory effects may be gestational dependent, related to maturation of vascular responses in different organs. These prenatal influences of congenital cardiac defects may severely affect immediate, as well as longterm, postnatal prognosis and survival. This has stimulated the development of techniques for palliation of disturbed circulation during fetal life.

    Birth cohort studies of developmental defects of enamel (DDE) and early childhood caries (ECC) in very low birthweight (VLBW) and normal birthweight (NBW) infants are rare. In this birth cohort of 234 VLBW and 234 NBW infants, we report the incidence of ECC and DDE at 8 and 18-20 mos of corrected age. Infant medical and maternal socio-demographic data were abstracted from medical records at birth. Dental assessments for ECC and DDE (enamel hypoplasia, demarcated and diffuse opacities) were completed at 8 and 18-20 mos. The incidence of hypoplasia was significantly higher in VLBW compared with NBW infants (8 mos, 19% vs. 2%; 18 mos, 31% vs. 8%). The incidence of ECC (International Caries Detection and Assessment System: ICDAS ≥ 2) was 1.4% (8 mos) and 12% (18-20 mos) and was similar between the VLBW and NBW groups. At both ages, using a beta-binomial regression model to control for potential confounders (maternal and infant characteristics), we found increased risk for enamel hypoplasia among the VLBW infants compared with the NBW infants. African Americans had a lower risk for enamel hypoplasia at 18-20 mos. The VLBW infants should be monitored for ECC due to the presence of enamel hypoplasia.

    Forty-five patients with the common clinical factor of optic nerve hypoplasia are analyzed regarding their clinical appearance, echographic and computed tomographic measurements of the optic nerves, and the correlation of anatomic size with visual function. Computed axial tomographic studies of the midline brain were performed on all 45 patients to determine the incidence of correlated structural defects, especially the septum pellucidum, and neuroendocrine dysfunction. Review of the spectrum of septo-optic-pituitary syndrome is separately developed to include historical background, embryogenesis, histopathology, and pathogenesis of the three major components of the syndrome. In summary, 45 patients had optic nerve hypoplasia, 32 with evidence of segmental or partial hypoplasia and 13 with evidence of complete or diffuse hypoplasia--the optic nerve hypoplasia syndrome. Twelve of these patients demonstrated absence of the septum pellucidum by computed axial tomography--the septo-optic dysplasia syndrome. Of these 12 patients with partial or complete absence of the septum pellucidum, six demonstrated evidence of pituitary hypofunction--the septo-optic-pituitary dysplasia syndrome.

    Adrenal carcinoma is a rare malignancy of poor prognosis. The most common clinical presentation is secondary to hormone production, while the development of symptomatic hypoglycemia is exceptional. We report the case of a 37 year old-woman admitted to hospital with severe hypoglycemia, hypertension, hypokalemia and amenorrhea. In the laboratory we found hypoglycemia, with low insulin levels, and androgen levels in tumor range. CT of abdomen and pelvis showed a heterogeneous lesion of solid appearance without a cleavage plane relative to liver parenchyma, and intense contrast enhancement. Retroperitoneal mass was removed, and the patient evolved without complications, blood glucose and potassium were normalized, blood pressure stabilized and menstrual cycles recovered.

    Congenital Wilms tumor is a tumor of childhood. Here we present an unusual case of bilateral congenital Wilms tumor with associated ductal plate malformation. In addition, there was also associated oligohydramnios, pulmonary hypoplasia, and multiple skeletal anomalies in this index case. Although various syndromic associations of Wilms tumor are well described in the literature, an association of congenital Wilms tumor with ductal plate malformation, polysplenia, and skeletal malformations is not reported. We believe that this is the first reported case of such an association.

    Congenital torticollis is a very common postural deformity, characterized by a more or less severe retraction of sternocleidomastoid muscle. Any treatment, else that "good sense" counsels given to the parents, is indicated. The evolution is spontaneously favorable in the majority of cases before the age of one year old. The elimination of differential diagnosis (vertebral and/or neurological malformations, ocular, tumor) is the key-point. Screening of congenital hip dislocation is mandatory because the physiopathology is the same in both diseases. A remaining torticolis after 18 months of age may be an indication to sternocleidomastoid muscle lengthening.

    Zika virus (ZIKV) is a mosquito-borne arbovirus from the Flaviviridae family. It had caused several epidemics since its discovery in 1947, but there was no significant attention to this virus until the recent outbreak in Brazil in 2015. The main concern is the causal relationship between prenatal ZIKV infection and congenital microcephaly, which has been confirmed recently. Moreover, ZIKV may cause other central nervous system abnormalities such as brain parenchymal atrophy with secondary ventriculomegaly, intracranial calcification, malformations of cortical development (such as polymicrogyria, and lissencephaly-pachygyria), agenesis/hypoplasia of the corpus callosum, cerebellar and brainstem hypoplasia, sensorineural hearing-loss, and ocular abnormalities as well as arthrogryposis in the infected fetuses. Postnatal (acquired) ZIKV infection usually has an asymptomatic or mildly symptomatic course, while prenatal (congenital) ZIKV infection has a more severe course and may cause severe brain anomalies that are described as congenital Zika syndrome. In this pictorial essay, we aim to illustrate the prenatal and postnatal neuroimaging findings that may be seen in fetuses and neonates with congenital Zika syndrome, and will discuss possible radiological differential diagnoses. A detailed knowledge of these findings is paramount for an early correct diagnosis, prognosis determination, and counseling of the affected children and families.

    Agenesis or hypoplasia of the right or left pulmonary arteries are among the rarest pulmonary artery anomalies with left sided anomalies being reported even less frequently. Pulmonary artery agenesis should be suspected in asymptomatic patients if a plain chest X-ray shows asymmetric lung fields, lung hypoplasia, or hyperinflation of the contralateral lung. It must be considered as a rare cause of recurrent lower respiratory tract infections in childhood and in subjects with a low threshold for or recurrent "High Altitude Pulmonary Edema".

    The term “vertebrobasilar dolichoectasia” refers to anomalous dilatation of the intracranial arteries associated with elongation or tortuosity of the affected vessels. The etiology of the disease is unknown and is usually detected incidentally. The predominant clinical manifestations arise due to the mass effect of the dilated vessels and may include cranial nerve compression, extrinsic aqueductal compression, motor and sensory disturbances. Trigeminal hypoplasia is a very uncommon condition, usually described in association with Goldenhar-Gorlin syndrome and has not yet been attributed to vertebrobasilar dolichoectasia. The current case report highlights this rare association of trigeminal nerve hypoplasia and vertebrobasilar dolichoectasia, leading to hemifacial and corneal anesthesia. PMID:26167222

    Garcia-Filion, Pamela; Borchert, Mark

    2013-01-01

    Opinion statement Background Optic nerve hypoplasia (ONH) has developed into a leading cause of congenital blindness. The frequently associated features of hypopituitarism and absent septum pellucidum were felt to have embryonic linkage as “septo-optic dysplasia” or “de Morsier’s syndrome.” More recent studies have suggested these associations are independent of one another. This review provides an assessment of the historical and recent evidence linking neuroradiologic, endocrinologic and developmental morbidity in patients with ONH. The prenatal risk factors, heritability, and genetic mutations associated with ONH are described. Results Recognition of the critical association of ONH with hypopituitarism should be attributed to William Hoyt, not Georges de Morsier. De Morsier never described a case of ONH or recognized its association with hypopituitarism or missing septum pellucidum. Hypopituitarism is caused by hypothalamic dysfunction. This, and other more recently identified associations with ONH, such as developmental delay and autism, are independent of septum pellucidum development. Other common neuroradiographic associations such as corpus callosum hypoplasia, gyrus dysplasia, and cortical heterotopia may have prognostic significance. The predominant prenatal risk factors for ONH are primiparity and young maternal age. Presumed risk factors such as prenatal exposure to drugs and alcohol are not supported by scrutiny of the literature. Heritability and identified gene mutations in cases of ONH are rare. Conclusion Children with ONH require monitoring for many systemic, developmental, and even life-threatening problems independent of the severity of ONH and presence of brain malformations including abnormalities of the septum pellucidum. “Septo-optic dysplasia” and “de Morsier’s syndrome” are historically inaccurate and clinically misleading terms.

    Background: Nasomaxillary hypoplasia is a rare congenital disorder involving the central face. It imparts a distinctive appearance to the individual face as the age advances. Severity of the disorder varies, so do the manifestations. Methods: This was a retrospective study conducted on the records and photographic data of 560 rhinoplasty cases performed between 2006 March and 2016 March. About 16 cases of nasomaxillary hypoplasia were selected from the group and they were classified based on the severity of the features. Surgical correction performed in each group was detailed. Results: Three percent of the 560 rhinoplasties performed in our centre turned out to be cases of Binder's syndrome. Nasal correction with locoregional autologous cartilage grafts was sufficient in mild cases. Loco-regional cartilage grafts along with costal cartilage grafts were needed for moderate and severe cases. Anterior nasal floor along with alar base augmentation was performed to achieve a proper aesthetic profile in moderate and severe cases. Post-operative results were excellent in mild and moderate cases and acceptable in severe cases. Discussion: We attempted to correct the deformity only after growth of the nose and maxilla was completed. We used cartilage grafts as a mainstay as cartilage has long-term stability without resorption unlike bone grafts. Instead of following en bloc technique of cartilage assembly, we have reconstructed the nasal dorsum, columella and tip separately as this principle is more functionally acceptable with less warping or stiffness of the nose. Importance was given to proper anchorage of grafts. Conclusion: We have attempted to put together the various features into three categories of mild/moderate/severe based on previous anthropometric studies of nasal anatomical parameters. The second objective of our study was to advise a logical surgical protocol for each group so that future surgeons can follow an easy surgical guideline to attain optimal

    Diagnosing the cause of bovine congenital malformations (BCMs) is challenging for bovine veterinary practitioners and laboratory diagnosticians as many known as well as a large number of not-yet reported syndromes exist. Foetal infection with certain viruses, including bovine virus diarrhea virus (BVDV), Schmallenberg virus (SBV), blue tongue virus (BTV), Akabane virus (AKAV), or Aino virus (AV), is associated with a range of congenital malformations. It is tempting for veterinary practitioners to diagnose such infections based only on the morphology of the defective offspring. However, diagnosing a virus as a cause of BCMs usually requires laboratory examination and even in such cases, interpretation of findings may be challenging due to lack of experience regarding genetic defects causing similar lesions, even in cases where virus or congenital antibodies are present. Intrauterine infection of the foetus during the susceptible periods of development, i.e. around gestation days 60-180, by BVDV, SBV, BTV, AKAV and AV may cause malformations in the central nervous system, especially in the brain. Brain lesions typically consist of hydranencephaly, porencephaly, hydrocephalus and cerebellar hypoplasia, which in case of SBV, AKAV and AV infections may be associated by malformation of the axial and appendicular skeleton, e.g. arthrogryposis multiplex congenita. Doming of the calvarium is present in some, but not all, cases. None of these lesions are pathognomonic so diagnosing a viral cause based on gross lesions is uncertain. Several genetic defects share morphology with virus induced congenital malformations, so expert advice should be sought when BCMs are encountered.

    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."

    Adrenal masses are described in seven cases of non-Hodgkin lymphoma in a series of 173 patients. In all seven patients the lymphoma was diffuse rather than nodular. Three patients had adrenal masses at the time of presentation, whereas in four cases the adrenal gland was a site of tumor recurrence after therapy. Three patients had simultaneous bilateral adrenal involvement by tumor. No characteristic features were recognized that might have distinguished these tumors from other adrenal masses. Appropriate therapy successfully resolved the adrenal masses in all but one case. The latter patient was the only one with evidence of adrenal insufficiency.

    1986-05-01

    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

    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.

    The management of congenital scoliosis requires a systematic approach with careful attention to detail. Any fortuitous diagnosis of vertebral anomalies in infancy, even if there is no significant scoliosis at that time on x-ray, requires frequent clinical and radiographic follow-up to detect progression. The presence of associated anomalies of the spinal cord, the kidneys and the heart should be evaluated by MRI, renal ultrasound or IVP, with cardiology evaluation as indicated. Curve progression or severe vertebral anomalies known to cause curve progression require immediate treatment to prevent deformity. Significant thoracic deformity, especially in a patient with thoracic insufficiency syndrome, is best treated with expansion thoracoplasty. The patient with congenital scoliosis requires a long term commitment to care with frequent orthopaedic follow-up throughout the growing years along with routine pulmonary function assessment once the patient is able to cooperate with testing.

    2012-09-01

    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.

  11. Compensatory adrenal growth - A neurally mediated reflex

    The responses of young rats to left adrenalectomy or left adrenal manipulation were compared to surgical sham adrenalectomy in which adrenals were observed but not touched. At 12 h right adrenal wet weight, dry weight, DNA, RNA, and protein content were increased (P less than 0.05) after the first two operations. Left adrenal manipulation resulted in increased right adrenal weight at 12 h but no change in left adrenal weight. Sequential manipulation of the left adrenal at time 0 and the right adrenal at 12 h resulted in an enlarged right adrenal at 12 h (P less than 0.01), and an enlarged left adrenal at 24 h (P less than 0.05), showing that the manipulated gland was capable of response. Bilateral adrenal manipulation of the adrenal glands resulted in bilateral enlargement of 12 h (P less than 0.01). Taken together with previous results, these findings strongly suggest that compensatory adrenal growth is a neurally mediated reflex.

  12. Prenatal determinants of optic nerve hypoplasia: review of suggested correlates and future focus.

    Optic nerve hypoplasia (ONH), a congenital malformation characterized by an underdeveloped optic nerve, is a seemingly epidemic cause of childhood blindness and visual impairment with associated lifelong morbidity. Although the prenatal determinants of ONH are unknown, early case reports have led to a longstanding speculation that risky health behaviors (e.g., prenatal use of recreational drugs, alcohol) are a likely culprit. There has yet to be a systematic review of the epidemiology of ONH to assess the common prenatal features that may help focus research efforts in the identification of likely prenatal correlates. A review of the past 50 years of epidemiologic research was conducted to examine the prenatal features linked with ONH and provide direction for future research. There are select prominent prenatal features associated with ONH: young maternal age and primiparity. Commonly implicated prenatal exposures (recreational or pharmaceutical drugs, viral infection, etc.) were rare or uncommon in large cohort studies of ONH and therefore unlikely to be major contributors to ONH. Familial cases and gene mutations are rare. The preponderance of young mothers and primiparity among cases of ONH is striking, although the significance is unclear. Recent research suggests a potential role for prenatal nutrition, weight gain, and factors of deprivation. With the rapidly increasing prevalence of ONH, future research should focus on investigating the relevance of young maternal age and primiparity and exploring the recently suggested etiologic correlates in epidemic clusters of ONH.

  14. Aesthetic approach for anterior teeth with enamel hypoplasia

    PubMed Central

    2012-01-01

    Enamel hypoplasia is a developmental defect of the enamel that is produced by a disturbance in the formation of the organic enamel matrix, clinically visible as enamel defects. Disorders that occur during the stages of enamel development and maturation reduce the amount or thickness of the enamel, resulting in white spots, tiny grooves, depressions and fissures in the enamel surface. The complexity and intensity of the dental deformity lesions will conduct the ideal treatment-associating conservative techniques. This article presents a case report of a restorative treatment of enamel hypoplasia using hybrid composite resin to mask color alteration and enamel defects. An aesthetic appearance that respects the tooth polychromatic and the self-esteem of the patient can be achieved with this approach. PMID:22629075

  15. Hypoplastic area method for analyzing dental enamel hypoplasia.

    PubMed

    Ensor, B E; Irish, J D

    1995-12-01

    Most analyses of dental enamel hypoplasia compare frequencies of disturbed tooth types, which do not account for variability in the area of affected enamel. An alternate methodology, hypoplastic area, is presented here that accounts for this variability by combining acute and continuous enamel hypoplasia into an interval-level variable. The method compares samples based on individuals, by multiple tooth type variables, or by a single value rather than by tooth types. Use of the hypoplastic area method is illustrated by analyzing human skeletal dentitions in three archaeological samples: Meroitic Nubians from Semna South, Sudan; Anasazi from Navajo Reservoir, New Mexico; and Mogollon from Grasshopper Pueblo, Arizona. Both univariate and multivariate statistical tests are employed to assess variation in defects between individuals and samples. By incorporating measurements of continuous defects, the hypoplastic area method provides information beyond that of frequency data in comparing levels of stress. Flexibility of the method is also discussed.

    The prune belly syndrome (OMIM 100100) is an association of bladder dilation with hypoplasia of the abdominal wall muscles. This malformation sequence is due to early urethral obstruction. We report a family with abdominal wall muscular hypoplasia as an isolated defect, not associated with the urethral obstruction sequence. The proband is a q3-year-old male who presented with abdominal wall laxity and severe constipation. His mother, maternal grandmother and younger brother had varying degrees of abdominal wall muscular deficiency and constipation. His mother's condition was aggravated by her 2 pregnancies. This family shows vertical transmission (compatible with autosomal dominant or mitochondrial inheritance) of the abdominal phenotype of prune belly sequence without any evidence of urinary tract or renal pathology. The expression in the sons may remain incomplete because abdominal distention due to pregnancy will not occur.

    Becker nevus syndrome (BNS) is a rare epidermal nevus syndrome characterized with Becker nevus and ipsilateral breast gland hypoplasia or other skin, skeletal and/or muscle tissue disorders. A 24-year-old woman presented with brown, irregular bordered patch with a diameter of approximately 10 cm which consisted of several small macules on the left breast skin. The ultrasonography and magnetic resonance imaging revealed left breast hypoplasia. Histopathological examination demonstrated minimal acanthosis, papillomatosis, increase in basal layer melanin and hypertrophy of the erector pili muscle. Immunohistochemical staining was positive for androgen in the epidermis, dermal stromal cells and skin appendages. Depending on the clinical and histopathological findings, the patient was diagnosed as BNS. Diagnosis of BNS needs careful examination of pigmented macules and patches since non-hairy BN may be easily overlooked. Patients with BN should be evaluated for associated abnormalities of BNS, in which the severity and extend of ectodermal involvement may differ from patient to other. PMID:25484431

    A 22-year-old male patient was admitted with severe cough associated with purulent expectoration, left-sided chest pain and breathlessness. There was a history of recurrent respiratory ailments since childhood. The patient appeared younger than his chronological age. His face and ears were both dysmorphic. Clinically, the patient was diagnosed with Ehlers-Danlos syndrome (EDS). Computed tomography of the thoracic region revealed hypoplasia of the left lung and hyperplasia of the right lung. Both the patellae were absent. However, ultrasonography of his abdomen, echocardiography and other routine blood and urine examination showed no gross abnormalities. Although other respiratory tract abnormalities with EDS are not uncommon, unilateral lung hypoplasia and patellar agenesis in EDS make this case unique.

    Congenital aniridia is a rare condition related to a deficiency in the PAX6 gene expression, which may occur as a result of a family inheritance or a sporadic occurrence. Additionally, this condition may occur as an isolated ocular phenotype or in association with a systemic syndrome. The most common abnormality is iris hypoplasia; however, a panocular disease which also affects the cornea, anterior chamber of the eye, lens, and the posterior segment with presence of optic nerve and foveal hypoplasia is also evident. The development of keratopathy, glaucoma, and cataract is frequent and its presence has implications in the patient's visual acuity. Managing aniridia is challenging since the focus is on treating the previously mentioned disorders, and the outcomes are often disappointing. In this paper, we shall review the epidemiology, pathophysiology, and clinical characteristics of patients with aniridia. We shall also make a review of the therapeutic options for the several conditions affecting this syndrome and consider the genetics and prognostic factors. PMID:27355034

    Cartilage-hair-hypoplasia is a rare autosomal recessive metaphyseal dysplasia due to RMRP (the RNA component of the RNase MRP ribonuclease mitochondrial RNA processing complex) gene mutations. So far, about 100 mutations have been reported in the promoter and the transcribed regions. Clinical characteristics include short-limbed short stature, sparse hair and defective cell-mediated immunity. We report herein the antenatal presentation of a female foetus, in whom CHH was suspected from 23 weeks' gestation, leading to a medical termination of the pregnancy at 34 weeks gestation, and thereafter confirmed by morphological and molecular studies. Post-mortem examination confirmed short stature and limbs, and revealed thymic hypoplasia associated with severe CD4 T-cell immunodeficiency along with extensive non caseating epithelioid granulomas in almost all organs, which to our knowledge has been described only in five cases. Molecular studies evidenced on one allele the most frequently reported founder mutation NR_003051: g.70A>G, which is present in 92% of Finnish patients with Cartilage Hair Hypoplasia. On the second allele, a novel mutation consisting of a 10 nucleotide insertion at position -18 of the promoter region of the RMRP gene (M29916.1:g.726_727insCTCACTACTC) was detected. The founder mutation was inherited from the father, and the novel mutation from the mother. To our knowledge, this case report represents the first detailed foetal analysis described in the literature.

    Over the past decade, amniotic fluid-derived stem cells have emerged as a novel, experimental approach for the treatment of a wide variety of congenital anomalies diagnosed either in utero or postnatally. There are a number of unique properties of amniotic fluid stem cells that have allowed it to become a major research focus. These include the relative ease of accessing amniotic fluid cells in a minimally invasive fashion by amniocentesis as well as the relatively rich population of progenitor cells obtained from a small aliquot of fluid. Mesenchymal stem cells, c-kit positive stem cells, as well as induced pluripotent stem cells have all been derived from human amniotic fluid in recent years. This article gives a pediatric surgeon’s perspective on amniotic fluid stem cell therapy for the management of congenital anomalies. The current status in the use of amniotic fluid-derived stem cells, particularly as they relate as substrates in tissue engineering-based applications, is described in various animal models. A roadmap for further study and eventual clinical application is also proposed. PMID:22986340

    Toxoplasmosis is caused by infection with the parasite Toxoplasma gondii. It is one of the most common parasitic infections in humans and is most typically asymptomatic. However, primary infection in a pregnant woman can cause severe and disabling disease in the developing fetus. Recent developments have included increased understanding of the role of parasite genotype in determining infectivity and disease severity. Risk factors for acquisition of infection have been better defined, and the important role of foodborne transmission has been further delineated. In addition, strategies have emerged to decrease mother-to-child transmission through prompt identification of acutely infected pregnant women followed by appropriate treatment. Refined diagnostic tools, particularly the addition of immunoglobulin G avidity testing, allow for more accurate timing of maternal infection and hence better decision making during pregnancy. Congenitally infected children can be treated, beginning in utero and continuing through the first year of life, to ameliorate the severity of disease. However, despite these many advances in our understanding of congenital toxoplasmosis prevention and treatment, significant areas of study remain: we need better drugs, well defined strategies for screening of pregnant women, improved food safety, and improved diagnostic tests.

    Adrenal gland disease in ferrets is unique to this species, with clinical signs and pathophysiology different from those seen in the dog. Its prevalence is increasing; 70% of pet ferrets in the United States were affected in 2003. The exact causes of the adrenal gland changes that lead to the disease are not known. Early oophorohysterectomies and neutering, combined with the artificially prolonged photoperiod experienced by indoor pet ferrets, and a possible genetic component, may be contributing factors. Signs of adrenal gland disease include progressive hair loss, pruritus, lethargy, atrophy, and, in female ferrets, vulvar swelling. An understanding of the signs and physiologic changes is necessary for diagnosis and treatment. A review of anatomy, physiology, and current surgical and medical options is presented.

    Immune and endocrine systems are basic regulatory mechanisms of organism and, including the nervous system, maintain the organism's homeostasis. The main immune system representatives are mononuclear cells, T- and B-cells and their products, in the endocrine system the main representatives are cells of the glands with inner secretion and their products. One of the most important glands for maintaining homeostasis are adrenal glands. It has been proven that either cells of the immune system, either endocrine cells can, although in trace amounts, produce mutually mediators of both systems (hormones, cytokines). Disorders in one system can lead to pathological symptoms in the other system. Also here represent adrenals an important model.

    Fryns syndrome is a multiple congenital anomaly syndrome with an autosomal recessive inheritance. Here we describe the autopsy case findings of a 19-week male fetus, born out of a consanguineous marriage. The dissection revealed left-sided diaphragmatic hernia, resulting in pulmonary hypoplasia and shift of heart to the right side. In addition, anencephaly and spina bifida throughout the vertebral column were observed. All six criteria for Fryns syndrome were met. Such a presentation of Fryns syndrome associated with Craniorachischisis Totalis has not been reported so far. We have also tabulated the overlapping features of some multiple congenital anomaly syndromes that need to be distinguished at autopsy for an accurate diagnosis.

    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 (CA) biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers) are presently being used 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 β ARs (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 α2AR 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 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 HF pathophysiology and in the identification of new therapeutic targets.

    A 4-month-old female Holstein Friesian calf was referred to the Veterinary Teaching Hospital, University of Berne, Switzerland for evaluation of ataxia, weakness, apathy and stunted growth. Clinical examination revealed generalized ataxia, propioceptive deficits, decreased menace response and sensibility. Postmortem examination did not reveal macroscopic changes of major organs. Histologically, the brain and the spinal cord lesions were characterized by polymicrocavitation, preferentially affecting the white matter fibers at the junction of grey and white matter and by the presence of Alzheimer type II cells. The liver revealed lesions consistent with a congenital portosystemic shunt, characterized by increased numbers of arteriolar profiles and hypoplasia to absence of portal veins. The pathological investigations along with the animal history and clinical signs indicated a hepatic encephalomyelopathy due to a congenital portosystemic shunt.

    Infection with Ehrlichia canis should be suspected in patients with fever, headache, malaise, leukopenia, thrombocytopenia, and a history of recent exposure to ticks. The cytopenia is caused by bone marrow hypoplasia which may be severe. The disease may be confused with spotless Rocky Mountain spotted fever but can be differentiated from this infection serologically with acute and convalescent sea. In humans, recovery has occurred with and without antibiotic therapy. However, prompt antibiotic therapy is advised prior to serologic studies, especially in immunocompromised individuals, splenectomized persons, and patients with AIDS-who may develop a more overwhelming rickettsial infection.

    The French national neonatal screening program for congenital hypothyroidism (CH) was initiated in 1978. The purpose of this study was to ascertain the incidence of congenital extrathyroid anomalies (ETAs) among the infants with congenital hypothyroidism (CH) and to compare it with the Northeastern France Birth Defect Monitoring System data from 1979 to 1996. Among 129 CH infants on whom adequate data were available, 20 infants (15.5%) had associated congenital anomalies. Eight out of 76 infants with persistent CH had ETAs (10.5%) whereas 12 out of 53 children with transient hypothyroidism had ETAs (22.6%, p < 0.05). Some additional anomalies were considerably more common than in the general population. Nine infants had congenital cardiac anomalies (6.9%). This rises the question if teratogenic effects active during organogenesis may affect simultaneously many organs, including the developing thyroid, causing a relatively high percentage of CH infants with congenital ETAs.

    This case report describes an exceptional case of ectopic adrenal cortex tissue (EACT) in the spermatic cord associated with ipsilateral cryptorchidism in an adult. While both EACT and cryptorchidism are fairly common congenital anomalies in boys, adult cases are uncommon. Although the spermatic cord is a known site of EACT, the reports of its association with cryptorchidism have been limited to child cases. During surgery, undescended testis was discovered and incidentally ectopic adrenal tissue along the spermatic cord was also identified. This combination of developmental aberrations in the adult has not been described, and the clinicopathological findings are reported with a brief literature review.

    2016-03-01

    Focal dermal hypoplasia (FDH) or Goltz Syndrome (OMIM# 305600) is an X-linked dominant ectodermal dysplasia caused by mutations in the PORCN gene. This gene encodes an endoplasmic reticulum transmembrane protein that is involved in processing the embryonically critical WNT signaling proteins. Individuals diagnosed with FDH were recruited to participate in the study through the National Foundation for Ectodermal Dysplasia. Individuals were evaluated to characterize the FDH phenotype. Each participant completed a brief dental survey and oral evaluation using artificial light. To identify the oral soft and hard tissue findings 19 individuals (16 female and 3 male) participated with a median age of 10 years (range 2-56 years). Soft and hard tissue defects were present in 68% (13) and 94% (18) of the patients, respectively. Dental anomalies were highly prevalent with 68% (13) demonstrating vertical enamel grooving, 52% (10) having peg shaped tooth deformities, and 78% (15) having enamel hypoplasia with or without discoloration. Cleft lip and cleft palate presented in 15% (3) of the participants. Other findings included 57% (11) having intra-oral lipoma or papilloma with no site predilection. Dental malocclusions were common with 63% (12) having some degree of malocclusion with 15% (3) of participants having class III malocclusion with an anterior dental cross bite. Participants frequently reported speech problems or difficulty with chewing (73%; N = 14). This study shows there is marked variation in the oral phenotype of individuals with FDH and underscores the important role of WNT signaling in oro-facial development.

    Objective: To assess the natural history of congenital myopathies (CMs) due to different genotypes. Methods: Retrospective cross-sectional study based on case-note review of 125 patients affected by CM, followed at a single pediatric neuromuscular center, between 1984 and 2012. Results: Genetic characterization was achieved in 99 of 125 cases (79.2%), with RYR1 most frequently implicated (44/125). Neonatal/infantile onset was observed in 76%. At birth, 30.4% required respiratory support, and 25.2% nasogastric feeding. Twelve percent died, mainly within the first year, associated with mutations in ACTA1, MTM1, or KLHL40. All RYR1-mutated cases survived and did not require long-term ventilator support including those with severe neonatal onset; however, recessive cases were more likely to require gastrostomy insertion (p = 0.0028) compared with dominant cases. Independent ambulation was achieved in 74.1% of all patients; 62.9% were late walkers. Among ambulant patients, 9% eventually became wheelchair-dependent. Scoliosis of variable severity was reported in 40%, with 1/3 of (both ambulant and nonambulant) patients requiring surgery. Bulbar involvement was present in 46.4% and required gastrostomy placement in 28.8% (at a mean age of 2.7 years). Respiratory impairment of variable severity was a feature in 64.1%; approximately half of these patients required nocturnal noninvasive ventilation due to respiratory failure (at a mean age of 8.5 years). Conclusions: We describe the long-term outcome of a large cohort of patients with CMs. While overall course is stable, we demonstrate a wide clinical spectrum with motor deterioration in a subset of cases. Severity in the neonatal/infantile period is critical for survival, with clear genotype-phenotype correlations that may inform future counseling. PMID:25428687

  5. Rare adrenal tumors in children.

    Apart from neuroblastomas, adrenal tumors are exceedingly rare in children and young adults. In this age group, the vast majority of patients present with clinical signs associated with excess hormone production. The most common tumor to arise from the adrenal cortex is an adrenocortical carcinoma (ACC). Similar to the situation in adults, this tumor is frequently diagnosed at a late stage and carries a very poor prognosis. ACCs require extensive/aggressive local resection followed by mitotane chemotherapy. A multidisciplinary approach is essential, and these children should be referred to units that have previous experience in managing ACCs. International registries are an invaluable source for evidence-based care, and such collaborations should be further developed in the future. Pheochromocytomas are derived from the adrenal medulla and present with symptoms caused by high secretion of catecholamines. At least one-third of these children will be found to carry genetic mutations, most commonly the RET gene (MEN2 syndrome) or the VHL gene. Open radical adrenalectomy should be offered to children with adrenocortical cancers. For all other cases, laparoscopic adrenalectomy is the treatment of choice. It is possible that the retroperitoneoscopic approach will gain increasing favor. The role of robotic adrenalectomy remains controversial.

    Ewing's sarcoma, also called primitive neuroectodermal tumour of the adrenal gland, is extremely rare. Only a few cases have been reported in the literature. We report on a woman with adult-onset primitive neuroectodermal tumour of the adrenal gland presenting with progressive flank pain. Computed tomography confirmed an adrenal tumour with invasion of the left diaphragm and kidney. Radical surgery was performed and the pain completely resolved; histology confirmed the presence of primitive neuroectodermal tumour, for which she was given chemotherapy. The clinical presentation of this condition is non-specific, and a definitive diagnosis is based on a combination of histology, as well as immunohistochemical and cytogenic analysis. According to the literature, these tumours demonstrate rapid growth and aggressive behaviour but there are no well-established guidelines or treatment strategies. Nevertheless, surgery remains the mainstay of local disease control; curative surgery can be performed in most patients. Adjuvant chemoirradiation has been advocated yet no consensus is available. The prognosis of patients with primitive neuroectodermal tumours remains poor.

    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.

    Eight patients admitted to a University hospital with acute surgical problems and related adrenal insufficiency were reviewed and three are presented in detail. Surgical stress and continued sepsis played major roles in the lack of responsiveness to usual modes of therapy until the adrenal insufficiency was corrected. The patients fell into three major clinical categories of adrenal insufficiency. Chronic illness and sepsis are shown to affect steroid production and metabolism, as well as adrenal responsiveness to ACTH. Pharmacologic amounts of steroids are often needed in patients with shock, gram negative sepsis and prolonged illnesses, even if normal or elevated serum cortisols are present. Therapeutic trials of cortisol administration are shown to be confusing when not accompanied by easily performed diagnostic tests of adrenal function. It is emphasized that a pretreatment serum cortisol should be obtained whenever possible. The evaluation of adrenal function is of lifelong importance to the patient. PMID:165792

    Congenital heart malformations are the most common of all birth defects, affecting 0.5-1% of all live births. Some of these malformations are due to genetic anomalies. Patterns of autosomal dominant, autosomal recessive and X-linked inheritance have been described. Mitochondrial inheritance and chromosomal anomalies can also be responsible for congenital heart malformations. Several genes for congenital heart defects have been identified. We review current knowledge on the genetic etiology of congenital heart disease.

  10. Metabolism of adrenal cholesterol in man

    Borkowski, Abraham; Delcroix, Claude; Levin, Sam

    1972-01-01

    The kinetics of plasma and adrenal cholesteral equilibration were analyzed in patients undergoing bilateral adrenalectomy for generalized mammary carcinoma. A biological model is proposed to help in the understanding of adrenal cholesterol physiology. It comprises two intracellular compartments: (1) A compartment of free adrenal cholesterol which is small (of the order of 17 mg) but turns over very fast; it is renewed approximately 8 times per day: 3 times by the inflow of free plasma cholesterol, and 5 times by the hydrolysis of esterified adrenal cholesterol, the contribution of adrenal cholesterol synthesis appearing to be relatively small. (2) A compartment of esterified adrenal cholesterol which is 20 times larger; it is constantly renewed by in situ esterification and hydrolysis with a daily fractional turnover rate of the order of 0.25. The direct and selective accumulation of plasma cholesteryl esters is practically absent. Only free adrenal cholesterol returns to plasma, mostly after conversion into steroid “hormones.” However small the synthesis of adrenal cholesterol may be, it seems more important in the zona “reticularis.” On the other hand, the inflow of plasma cholesterol and the turnover of the free adrenal compartment tend to be faster in the zona “fasciculata.” The equilibration of plasma and adrenal cholesterol can proceed unmodified under conditions of ACTH suppression. In one patient with Cushing's disease the size of the two adrenal compartments was clearly increased but their equilibration with plasma cholesterol proceeded normally. In another patient the kinetics of hydrocortisone corresponded to those of free adrenal cholesterol in the control studies. PMID:4338119

    Hemorrhage of the kidneys and adrenal glands has many etiologies. In the adrenal glands, trauma, anticoagulation, stress, sepsis, surgery, and neoplasms are common causes of hemorrhage. In the kidneys, reasons for hemorrhage include trauma, bleeding diathesis, vascular diseases, infection, infarction, hemorrhagic cyst rupture, the Antopol-Goldman lesion, and neoplasms. Angiomyolipoma and renal cell carcinoma are the neoplasms most commonly associated with hemorrhage in the kidneys and adrenal cortical carcinoma, metastases, and pheochromocytoma are associated with hemorrhage in the adrenal glands. Understanding the computed tomography and magnetic resonance imaging features, and causes of hemorrhage in the kidneys and adrenal glands is critical. It is also important to keep in mind that mimickers of hemorrhage exist, including lymphoma in both the kidneys and adrenal glands, and melanoma metastases in the adrenal glands. Appropriate imaging follow-up of renal and adrenal hemorrhage should occur to exclude an underlying malignancy as the cause. If there is suspicion for malignancy that cannot be definitively diagnosed on imaging, surgery or biopsy may be warranted. Angiography may be indicated when there is a suspected underlying vascular disease. Unnecessary intervention, such as nephrectomy, may be avoided in patients with benign causes or no underlying disease. Appropriate management is dependent on accurate diagnosis of the cause of renal or adrenal hemorrhage and it is incumbent upon the radiologist to determine the etiology.

  13. The adrenal medulla and Parkinson's disease.

    This paper reviews the literature describing the condition of the adrenal medulla in Parkinson's disease. Parkinson's disease is a neurodegenerative disorder that is characterized primarily by the loss of dopaminergic neurons in the substantia nigra. Clinical observations have revealed that Parkinson's disease is also frequently accompanied by a variety of autonomic symptoms. The adrenal medulla is a major component of the autonomic nervous system. However, until recently this organ has not been of particular interest in Parkinson's disease. Early studies found histologic abnormalities in adrenal medullary cells, and several groups measured urinary and plasma catecholamines to determine general autonomic status. In the late 1980s adrenal medullary tissue was first transplanted to the caudate nucleus in an attempt to augment the decreased levels of dopamine, and thus treat the symptoms of Parkinson's disease. At this time the status of the adrenal medulla in this disease became clinically important. We measured the total catecholamine content of the parkinsonian adrenal medulla in tissue collected both at autopsy and in conjunction with adrenal-caudate transplants. Adrenal medullary catecholamines and several neuropeptides were severely depressed in parkinsonian glands. Thus, the adrenal medulla appears to be a target of the peripheral manifestations of Parkinson's disease.

    Congenital hypoplasia and dysplasia affect the postnatal development of organs, their physiological functioning in adulthood and the incidence of related diseases at an advanced age. Hypogonadic (hgn/hgn) rats are characterized by male sterility, reduced female fertility, progressive renal insufficiency and growth retardation, all controlled by a single recessive allele (hgn) located on chromosome 10. Since our previous studies indicated that the hypoplasia (dysplasia) of the affected organs was present at birth, we examined the embryonic pathogenesis. We mated hgn/hgn females to Brown Norway males and backcrossed F(1) males to hgn/hgn females. The resulting N(1) fetuses were genotyped using a hgn-linked microsatellite. Both sexes of hgn/hgn fetuses showed low body weight after embryonic day (ED) 15.5 and renal hypoplasia after ED 17.5. Their kidneys contained a reduced number of nephrons in a poorly formed nephrogenic zone and renal cortex. The hgn/hgn ovaries contained a small number of oogonia at ED 15.5 and oocytes after ED 17.5. Testicular growth defects were obvious after ED 17.5, and reduced numbers of Sertoli cells were detected at ED 19.5 and 21.5. The seminiferous cords in hgn/hgn testes contained more apoptotic and mitotic cells than those in +/hgn testes. These findings suggest that the phenotypes described in adult hgn/hgn rats result from embryonic hypogenesis, which continues to early postnatal stage and causes a reduction in functional tissues and cells. Since hgn/hgn rats have an insertion mutation in the microtubule-associated protein Spag5 gene, the embryonic hypogenesis described in hgn/hgn rats might result from defective cell proliferation.

    Treacher Collins syndrome is a disorder characterized by various congenital soft tissue anomalies involving hypoplasia of the zygoma, maxilla, and mandible. A variety of treatments have been reported to date. These treatments can be classified into 2 major types. The first type involves osteotomy for hard tissue such as the zygoma and mandible. The second type involves plastic surgery using bone grafting in the malar region and soft tissue repair of eyelid deformities. We devised a new treatment to comprehensively correct hard and soft tissue deformities in the upper half of the face of Treacher Collins patients. The aim was to "change facial features and make it difficult to tell that the patients have this disorder." This innovative treatment strategy consists of 3 stages: (1) placement of dermal fat graft from the lower eyelid to the malar subcutaneous area, (2) custom-made synthetic zygomatic bone grafting, and (3) Z-plasty flap transposition from the upper to the lower eyelid and superior repositioning and fixation of the lateral canthal tendon using a Mitek anchor system. This method was used on 4 patients with Treacher Collins syndrome who had moderate to severe hypoplasia of the zygomas and the lower eyelids. Facial features of these patients were markedly improved and very good results were obtained. There were no major complications intraoperatively or postoperatively in any of the patients during the series of treatments. In synthetic bone grafting in the second stage, the implant in some patients was in the way of the infraorbital nerve. Thus, the nerve was detached and then sutured under the microscope. Postoperatively, patients had almost full restoration of sensory nerve torpor within 5 to 6 months. We devised a 3-stage treatment to "change facial features" of patients with hypoplasia of the upper half of the face due to Treacher Collins syndrome. The treatment protocol provided a very effective way to treat deformities of the upper half of the face

    A co-existing right congenital diaphragmatic hernia and omphalocele is rare. We present images of a fetus diagnosed with this rare combination of anomalies. Early neonatal death occurred immediately after full-term birth due to severe respiratory insufficiency. In this case, disturbance of chest wall development due to the omphalocele rather than the diaphragmatic hernia was considered as the main cause of lung hypoplasia. Our experience suggests that caution should be exercised for severe respiratory insufficiency in a neonate with an omphalocele and diaphragmatic hernia, even in the absence of an intra-thoracic liver, one of the indicators of poor outcome for congenital diaphragmatic hernia.

    Townes-Brocks syndrome (TBS) is a rare autosomal dominant congenital disorder caused by mutations in the SALL1 gene. Its signs and symptoms overlap with other genetic syndromes, including VACTERL association, Pendred syndrome, Baller-Gerold syndrome, and cat eye syndrome. Structural vertebral abnormalities, hypoplasia of the thumb, and radial bone abnormalities, which are not usually associated with TBS, help in the differential diagnosis of these syndromes. We report the case of a family whose members were diagnosed with TBS with congenital hypothyroidism and had a novel SALL1 gene mutation.

    The involvement of the hemodynamic expertise in the operating room led to the development of new strategies aimed to improve both early and long-term outcome of patients with congenital heart disease. During the last decade, with the aim of preserving the pulmonary valve function, we embarked on a new surgical approach, which combines surgical and interventional techniques, which are performed in the operating room. We believe that the preservation of the pulmonary valve function can be extended to any patients with classic tetralogy of Fallot and other selected patients with congenital pulmonary valve hypoplasia and dysfunction.

    To describe associated ocular, neurologic, and systemic findings in a population of children with optic nerve hypoplasia, a retrospective chart review of 100 patients with optic nerve hypoplasia for the presence of neurologic, radiologic, and endocrine abnormalities was performed. Neuroimaging and endocrine studies were obtained in 65 cases. Visual acuity and associated ocular, neurologic, endocrine, systemic, and structural brain abnormalities were recorded. Seventy-five percent had bilateral optic nerve hypoplasia. Conditions previously associated with optic nerve hypoplasia and present in our patients include premature birth in 21%, fetal alcohol syndrome in 9%, maternal diabetes in 6%, and endocrine abnormalities in 6%. Developmental delay was present in 32%, cerebral palsy in 13%, and seizures in 12%. Of those imaged, 60% had an abnormal study. Neuroimaging showed abnormalities in ventricles or white- or gray-matter development in 29 patients, septo-optic dysplasia in 10, hydrocephalus in 10, and corpus callosum abnormalities in 8. There was an associated clinical neurologic abnormality in 57% of patients with bilateral optic nerve hypoplasia and in 32% of patients with unilateral optic nerve hypoplasia. Patients with unilateral and bilateral optic nerve hypoplasia frequently have a wide range and common occurrence of concomitant neurologic, endocrine, and systemic abnormalities.

    A 1.5-year-old Doberman pinscher was presented with sudden-onset of fever and malaise. Twelve days prior to presentation, fenbendazole therapy was initiated for a suspected lungworm infection. Results of a complete blood count on presentation showed pancytopenia, while histopathological evaluation of a bone marrow core sample revealed bone marrow hypoplasia of undetermined etiology. Bactericidal antibiotics and fluid therapy, as well as discontinuation of fenbendazole administration, led to a complete resolution of clinical and hematological abnormalities within 15 days. An idiosyncratic reaction to fenbendazole was suspected based on the absence of infectious, neoplastic, autoimmune, and toxic etiologies, as well as resolution of clinical signs and pancytopenia upon drug withdrawal.

    2000-07-01

    This study describes the expression of linear enamel hypoplasia (LEH), a sensitive dental indicator of physiological stress, in Thailand gibbons (Hylobates lar carpenteri). Previous studies of enamel hypoplasia in hominoids have focused on great apes, with little attention given to the expression of this stress indicator in gibbons. In that gibbons differ from both monkeys and great apes in numerous life history features, LEH expression in gibbons might be expected to show significant differences from both. In this study, 92 gibbon specimens from two sites in Thailand were compared with several samples of monkeys and great apes in their expression of LEH. The intertooth distribution of LEH in gibbons was compared to that of chimpanzees and rhesus monkeys. Gibbon populations from both sites exhibit LEH frequencies intermediate between those of the monkey samples, in which LEH prevalence is usually low, and those of the great ape samples, in which LEH prevalence is high. Gibbons differ significantly from monkeys, but not great apes, in the number of individuals whose teeth record multiple stress events. Multiple episodes of stress are rarely recorded in the teeth of monkeys, while multiple stress events occur with higher frequency in gibbons and great apes. Taxonomic variation in the duration of crown formation, the prominence and spacing of perikymata on dental crowns, life history features, and/or experience of physiological stress may explain these patterns. The intertooth distribution of LEH in gibbons is, for different reasons, unlike that of either chimpanzees or rhesus monkeys. The mandibular canines of gibbons have significantly more LEH than any of their other teeth. Aspects of crown morphology, perikymata prominence/spacing, enamel thickness, and crown formation spans are potential causes of taxonomic variation in the intertooth distribution of LEH.

    Adrenocortical carcinomas are relatively rare, but they are considered to be highly aggressive malignant tumors. Sarcomatoid carcinomas represent an even more aggressive type. Bilateral malignant adrenal tumors are extraordinary rare, except for those that represent metastatic spread from a primary neoplasm. Here we report a case of a 69-year-old woman who presented symptoms that raised strong suspicions of adrenal insufficiency. Bilateral adrenal masses, identified in the imaging study, were responsible for the clinical manifestation and surgically resected. Surgical specimens of the bilateral adrenal tumors shared histological features compatible with sarcomatoid carcinoma. It was very difficult to confirm that the sarcomatoid carcinomas were derived from the cortex of the adrenal glands, but careful morphological observation and the panel of antibodies used for immunohistochemistry made the diagnosis possible. This is the first report of sarcomatoid carcinomas involving both adrenal glands. It should be emphasized that sarcomatoid carcinoma can arise bilaterally from even functionally impaired adrenal glands.

    Adrenal crisis is a potential life threatening complication. The common causes of adrenal crisis are infections, surgical stress and abrupt cessation of steroid medications. Endocrine causes like Graves’ disease with thyrotoxicosis is one of the less common causes of an adrenal crisis. We report a 42-year-old female who presented with recurrent episodes of adrenal crisis due to delayed diagnosis of thyrotoxicosis. She was initially treated with Carbimazole followed by Radio-iodine ablation and currently she is euthyroid. Her adrenal insufficiency was initially treated with hydrocortisone during the time of adrenal crisis followed by Prednisolone 5 mg once daily in the morning along with fludrocortisone 50 mcg once daily. This case highlights the need for high index of suspicion and less common causes like thyrotoxicosis should be ruled out in patients with adrenal crisis. PMID:27190873

    Context: Primary adrenal insufficiency (PAI) is a life-threatening condition that is often due to monogenic causes in children. Although congenital adrenal hyperplasia occurs commonly, several other important molecular causes have been reported, often with overlapping clinical and biochemical features. The relative prevalence of these conditions is not known, but making a specific diagnosis can have important implications for management. Objective: The objective of the study was to investigate the clinical and molecular genetic characteristics of a nationwide cohort of children with PAI of unknown etiology. Design: A structured questionnaire was used to evaluate clinical, biochemical, and imaging data. Genetic analysis was performed using Haloplex capture and next-generation sequencing. Patients with congenital adrenal hyperplasia, adrenoleukodystrophy, autoimmune adrenal insufficiency, or obvious syndromic PAI were excluded. Setting: The study was conducted in 19 tertiary pediatric endocrinology clinics. Patients: Ninety-five children (48 females, aged 0–18 y, eight familial) with PAI of unknown etiology participated in the study. Results: A genetic diagnosis was obtained in 77 patients (81%). The range of etiologies was as follows: MC2R (n = 25), NR0B1 (n = 12), STAR (n = 11), CYP11A1 (n = 9), MRAP (n = 9), NNT (n = 7), ABCD1 (n = 2), NR5A1 (n = 1), and AAAS (n = 1). Recurrent mutations occurred in several genes, such as c.560delT in MC2R, p.R451W in CYP11A1, and c.IVS3ds+1delG in MRAP. Several important clinical and molecular insights emerged. Conclusion: This is the largest nationwide study of the molecular genetics of childhood PAI undertaken. Achieving a molecular diagnosis in more than 80% of children has important translational impact for counseling families, presymptomatic diagnosis, personalized treatment (eg, mineralocorticoid replacement), predicting comorbidities (eg, neurological, puberty/fertility), and targeting clinical genetic testing in the

    Congenital abnormalities of the temporal bone are mostly accompanied by conductive or sensori-neural hearing loss. Before any therapeutic procedures are done high resolution CT (HRCT) and magnetic resonance imaging (MRI) should be performed to establish the correct diagnosis and to plan the potentially surgical intervention. HRCT best depicts osseous changes especially those of the external auditory canal and the middle ear containing the ossicles and the osseous structures of the temporal bone and the petrous bone containing the inner ear. MRI excellently shows soft tissue changes of the inner ear especially on the high resolution 3DT2-weighted sequences which give a superb contrast between the nerves and the cerebro-spinal fluid. Malformations of the external auditory canal consists of aplasia or hypoplasia and those of the middle ear range form extreme hypoplasia or aplasia to very mild deformations of the ossicles. Malformations of the inner ear also range form complete aplasia to very mild hypoplasia of the organs of the inner ear as well as malformations concerning the nerves in the internal auditory canal range from aplasia to hypoplasia. Malformations of the temporal bone can either occur isolated or in combination in which malformations of the external and middle ear may be accompanied by those of the inner ear. Furthermore, malformations of the temporal bone may also occur in otofacial, otocervical or otoskeletal syndromes. These syndromes may be accompanied by certain malformations of the temporal bone. HRCT and MRI are both excellent methods to depict congenital abnormalities of the temporal bone and of the inner ear and should be used as complementary methods because HRCT best depicts osseous changes and MRI superbly depicts soft tissue changes. Both methods are important to establish the correct diagnosis to plan the therapeutic procedures.

    Linear enamel hypoplasia is a developmental disturbance of enamel resulting in clinically visible horizontal defects in enamel that are present on eruption of the tooth. Nondevelopmental lesions of the hard tissues of the tooth, including carious, abrasion, erosion, attrition, and abfraction lesions, require varying amounts of time after tooth eruption to develop. Because linear enamel hypoplasia lesions are present on eruption and are exposed to the factors responsible for abrasion, erosion, and abfraction, nondevelopmental lesions could occur within them in any combination. This report describes a patient with multiple teeth with linear enamel hypoplasia lesions containing nondevelopmental defects as well as nondevelopmental defects that occurred separately.

    Patients with nasomaxillary hypoplasia have severe facial concavity and compromised skeletal class III malocclusion. Its treatment is still a challenge to surgeons. Our aim was to evaluate the combination of midfacial distraction and orthognathic surgery in the treatment of nasomaxillary hypoplasia. Four patients with nasomaxillary hypoplasia were enrolled in this study. After Le Fort II osteotomy, the rotational distraction of nasomaxillary complex was performed to rehabilitate facial convexity. Then bilateral sagittal split ramus osteotomy with or without Le Fort I osteotomy was used to correct malocclusion. All patients healed uneventfully, and the maxillae moved forward conspicuously. No obvious pain and severe discomfort were complained during distraction. A significant advancement and downward movement of the maxilla were shown by cephalometric analysis. The combination of midfacial distraction and orthognathic surgery provides us an ideal alternative in the treatment of nasomaxillary hypoplasia.

    Sternal cleft anomalies are rare. Associated anomalies include pentalogy of Cantrell and posterior fossa abnormalities, hemangiomas, arteriopathy, cardiac anomalies, eye abnormalities, and sternal defects syndrome. There is only a single report of complete sternal cleft, pectus excavatum, and right clavicular hypoplasia in an adult. Thyroid hemiagenesis is also very rare. To our knowledge, this is the first case of complete sternal cleft, pectus deformity, and right clavicular hypoplasia in a child and the first case with right thyroid hemiagenesis.

    Recent studies have suggested that vertebral artery (VA) hypoplasia is a predisposing factor for posterior cerebral stroke. We examined whether anatomical vertebrobasilar ischemia, i.e., unilateral VA hypoplasia and insufficiency, impairs dynamic blood flow regulation. Twenty-eight female subjects were divided into three groups by defined criteria: (i) unilateral VA hypoplasia (n = 8), (ii) VA insufficiency (n = 6), and (iii) control (n = 14). Hypoplastic VA criterion was VA blood flow of 40 ml min(-1) , whereas VA insufficiency criterion was net (left + right) VA blood flow of 100 ml min(-1) or less. We evaluated left, right, and net VA blood flows by ultrasonography during hypercapnia, normocapnia, and hypocapnia to evaluate VA CO2 reactivity. The unilateral VA hypoplasia group showed lower CO2 reactivity at hypoplastic VA than at non-hypoplastic VA (2.65 ± 0.58 versus 3.00 ± 0.48% per mmHg, P = 0.027) and net VA CO2 reactivity was preserved (Unilateral VA hypoplasia, 2.95 ± 0.48 versus Control, 2.93 ± 0.42% per mmHg, P = 0.992). However, the VA insufficiency group showed a lower net VA CO2 reactivity compared to the control (2.29 ± 0.55 versus 2.93 ± 0.42% per mmHg, P = 0.032) and the unilateral VA hypoplasia (P = 0.046). VA hypoplasia reduced CO2 reactivity, although non-hypoplastic VA may compensate this regulatory limitation. In subjects with VA insufficiency, lowered CO2 reactivity at the both VA could not preserve normal net VA CO2 reactivity. These findings provide a possible physiological mechanism for the increased risk of posterior cerebral stroke in subjects with VA hypoplasia and insufficiency.

    1993-03-01

    With increasing incrimination of viruses, plants, and drugs as causes of ovine congenital defects, concerted efforts are required to identify environmental teratogens. Expanding knowledge of congenital defects requires studying as many defective lambs as possible; recording and documenting; detailed diagnostic examinations; genetic analyses and chromosomal examinations, whenever possible; and field investigations. Adopting standardized classification, terminology, and diagnostic procedures should improve descriptions, diagnoses, and interdisciplinary exchange of information. That, in turn, should improve our knowledge of and diagnosis of congenital defects of sheep in the future. Finally, veterinary clinicians and diagnosticians are encouraged to take an interest in congenital defects and teratology.

    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.

  17. Clinicopathological correlates of adrenal Cushing's syndrome.

    Duan, Kai; Gomez Hernandez, Karen; Mete, Ozgur

    2015-03-01

    Endogenous Cushing's syndrome is a rare endocrine disorder that incurs significant cardiovascular morbidity and mortality, due to glucocorticoid excess. It comprises adrenal (20%) and non-adrenal (80%) aetiologies. While the majority of cases are attributed to pituitary or ectopic corticotropin (ACTH) overproduction, primary cortisol-producing adrenal cortical lesions are increasingly recognised in the pathophysiology of Cushing's syndrome. Our understanding of this disease has progressed substantially over the past decade. Recently, important mechanisms underlying the pathogenesis of adrenal hypercortisolism have been elucidated with the discovery of mutations in cyclic AMP signalling (PRKACA, PRKAR1A, GNAS, PDE11A, PDE8B), armadillo repeat containing 5 gene (ARMC5) a putative tumour suppressor gene, aberrant G-protein-coupled receptors, and intra-adrenal secretion of ACTH. Accurate subtyping of Cushing's syndrome is crucial for treatment decision-making and requires a complete integration of clinical, biochemical, imaging and pathology findings. Pathological correlates in the adrenal glands include hyperplasia, adenoma and carcinoma. While the most common presentation is diffuse adrenocortical hyperplasia secondary to excess ACTH production, this entity is usually treated with pituitary or ectopic tumour resection. Therefore, when confronted with adrenalectomy specimens in the setting of Cushing's syndrome, surgical pathologists are most commonly exposed to adrenocortical adenomas, carcinomas and primary macronodular or micronodular hyperplasia. This review provides an update on the rapidly evolving knowledge of adrenal Cushing's syndrome and discusses the clinicopathological correlations of this important disease.

    Corticomedullary mixed tumors of the adrenal gland are quite rare, with only five well-documented cases reported in the literature.(1-4) Herein, we report the light microscopic and immunohistochemical features of two cases of this rare tumor. Patient 1 is a 34-year-old woman who presented with hypertension, hair loss, and amenorrhea of 1-year duration. Patient 2 is a 52-year-old woman who presented with flank pain and what appeared to be a renal mass on arteriogram with no history of hypertension, Cushing's syndrome, or other endocrine abnormalities. At surgery, the tumor was noted to arise from the adrenal gland rather than the kidney and adrenalectomy was performed. In both cases, the surgically resected specimens consisted of a well-circumscribed, single adrenal mass surrounded by a rim of uninvolved adrenal cortical tissue. The tumors were composed of adrenal cortical cells intimately admixed with pheochromocytes. Immunohistochemical studies highlighted these two cellular components. The pheochromocytes were strongly reactive with chromogranin and the sustentacular cells with S-100 protein, whereas the adrenal cortical cells reacted specifically with inhibin. Thus, we report two additional cases of mixed corticomedullary tumor of the adrenal gland. Ann Diagn Pathol 5:304-308, 2001. This is a US government work. There are no restrictions on its use.

    The ocular albinism type I (OA1) is clinically characterized by impaired visual acuity, nystagmus, iris hypopigmentation with translucency, albinotic fundus, and macular hypoplasia together with normally pigmented skin and hair. However, it is easily misdiagnosed as congenital idiopathic nystagmus in some Chinese patients with OA1 caused by the G-protein coupled receptor 143 (GPR143) gene mutations. Mutations in the FERM domain–containing 7 (FRMD7) gene are responsible for the X-linked congenital idiopathic nystagmus. In this study, five Chinese families initially diagnosed as X-linked congenital nystagmus were recruited and patients underwent ophthalmological examinations. After direct sequencing of the FRMD7 and GPR143 genes, five mutations in GPR143 gene were detected in each of the five families, including a novel nonsense mutation of c.333G>A (p.W111X), two novel splicing mutations of c.360+1G>C and c.659-1G>A, a novel small deletion mutation of c.43_50dupGACGCAGC (p.L20PfsX25), and a previously reported missense mutation of c.703G>A (p.E235K). Optical coherence tomography (OCT) examination showed foveal hypoplasia in all the affected patients with nystagmus. Our study further expands the GPR143 mutation spectrum and contributes to the study of GPR143 molecular pathogenesis. Molecular diagnosis and optical coherence tomography (OCT) are two useful tools for differential diagnosis. PMID:26160353

    A 56-year-old woman presented with an incidental adrenal adenoma and physical examination findings that included moderate obesity, a slight cervicothoracic fat pad ("buffalo hump"), increased supraclavicular fat pads, and white abdominal striae. Biochemical workup revealed elevated levels of 24-hour urinary free cortisol but normal serum morning cortisol and suppressed levels of corticotropin, suggestive of adrenal-dependent Cushing syndrome. The resected adrenal gland revealed macronodular cortical hyperplasia with a dominant nodule. Other findings included an absent cortisol response to corticotropin stimulation, presence of serum anti-21-hydroxylase antibodies, and mononuclear cell infiltration--consistent with adrenalitis. The findings represent, to the authors' knowledge, the first known case of a patient with coexistent functional cortisol-secreting macronodular adrenal tumor resulting in Cushing syndrome and immune-mediated adrenalitis resulting in Addison disease.

    A 60-year-old woman was admitted with severe hyponatremia. Basal values of adrenocorticotropic hormone (ACTH), thyroid hormone and cortisol were normal on admission. Impairment of water diuresis was observed by water loading test. Initially, we diagnosed her condition as the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). By provocation test, we finally confirmed that the hyponatremia was caused by hypothalamic adrenal insufficiency. The basal values of ACTH and cortisol might not be sufficient to exclude the possibility of adrenal insufficiency. Therefore, it is necessary to evaluate adrenal function by provocation test or to re-evaluate it after recovery from hyponatremia.

    Spontaneous adrenal hemorrhage (SAH) is a serious medical condition associated with variable clinical presentation depending on the extent of the hemorrhage. Pregnancy-induced adrenal hemorrhage is poorly understood. A low cortisol level in the peripartum period with radiological findings is sufficient to establish the diagnosis. Prompt hormone replacement and supportive care to ensure good clinical outcomes is crucial. Due to the potentially life-threatening complications, physicians should have a high suspicion for adrenal hemorrhage when they evaluate patients with hypotension, fatigue, and abdominal pain during the peripartum period.

    Kisspeptins are neuropeptides which activate the hypothalamo-pituitary gonadal axis and are considered to play important physiological roles in the reproduction. Kisspeptins have also been reported to stimulate the aldosterone secretion from the adrenal cortex. However, the expression of kisspeptins in human adrenal glands and adrenal tumors has not been clarified yet. We, therefore, studied the presence of kisspeptin-like immunoreactivity (LI) in human adrenal glands and adrenal tumors (adrenocortical adenomas, adrenocortical carcinomas, and pheochromocytomas) by radioimmunoassay and immunocytochemistry. Kisspeptin-LI was detected in all the tissues examined; normal portions of adrenal glands (3.0 +/- 2.3 pmol/g wet weight, n = 21, mean +/- SD), aldosterone-producing adenomas (4.6 +/- 3.3 pmol/g wet weight, n = 10), cortisol-producing adenomas (2.7 +/- 1.4 pmol/g wet weight, n = 14), adrenocortical carcinomas (1.7 +/- 0.2 pmol/g wet weight, n = 4), and pheochromocytomas (1.8 +/- 0.8 pmol/g wet weight, n = 6). There was no significant difference in kisspeptin-LI levels among them. Immunocytochemistry showed positive kisspeptin-immunostaining in normal adrenal glands, with stronger immunostaining found in the medulla. Furthermore, positive kisspeptin-immunostaining was found in all types of adrenal tumors examined; adrenocortical adenomas, adrenocortical carcinomas, and pheochromocytomas. The intensity of kisspeptin-immunostaining in these adrenal tumors was, however, not so strong as that in normal adrenal medulla. The present study has shown for the first time the presence of kisspeptin-LI in adrenal glands and adrenal tumors.

    Summary 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. Learning points The clinical presentation of Cushing’ syndrome includes symptoms and signs of fat redistribution and protein-wasting features. The diagnosis of patients with ACTH-independent Cushing’s syndrome with bilateral adrenal masses is challenging for localisation of the lesion. Both adrenal venous sampling and 131I-NP-59 scintigraphy are good methods to use in these patients with Cushing’s syndrome presenting with bilateral adrenal masses. PMID:27252858

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Unidentified bright objects (UBO) and tumors are well-known cerebellar abnormalities in neurofibromatosis type 1 (NF1). Literature reports on malformative cerebellar anomalies in neurofibromatosis type 1 (NF1), however, are scant. We retrospectively studied the clinical and neuroimaging findings of 5 patients with NF1 (4 females, age 6 to 29 years at last follow-up) and cerebellar anomalies. Cerebellar symptoms on neurological examination were mild or even not evident whereas learning disabilities were more or less pronounced in four patients. Two patients had cerebellar hypoplasia (diffusely enlarged cerebellar interfoliar spaces) and three cerebellar dysmorphias involving mainly one cerebellar hemisphere. In NF1, malformative cerebellar anomalies are rare (estimated prevalence of about 1%), but most likely underestimated and easily overlooked, because physicians tend to focus on more prevalent, obvious, and well-known findings such as optic pathway gliomas, other tumors, and UBO. This kind of cerebellar anomaly in NF1 has most likely a malformative origin, but the exact pathogenesis is unknown. The individual clinical significance is difficult to determine. We suggest that cerebellar anomalies should be systematically evaluated in neuroimaging studies of NF1 patients.

    We investigated retinal structure and function in eyes with optic nerve hypoplasia (ONH). Twenty-nine eyes of 18 patients with ONH and 21 eyes of 21 control patients were analyzed. Spectral-domain optical coherence tomography (SD-OCT), full-field electroretinography (FF-ERG), and focal macular ERG (FM-ERG) were performed. SD-OCT analysis of the macular region showed significant ganglion cells complex (GCC) thinning nasally and temporally (P < 0.05), but the thickness from the inner nuclear layer (INL) to the retinal pigment epithelium (RPE) became thinner only nasally (P < 0.05). SD-OCT analysis of the circumpapillary region showed significant thinning in the retinal nerve fiber layer and from the INL to the RPE (P < 0.05). The horizontal SD-OCT images showed variable foveal abnormalities. FF-ERG analysis showed significantly reduced amplitudes (P < 0.05) and preserved implicit time in the photopic negative response. The amplitudes and implicit times of the other FF-ERG components did not differ significantly. FM-ERG analysis showed significantly reduced amplitudes (P < 0.05) but preserved implicit times in all components. The current study showed the change of retinal structure and function in eyes with ONH compared with those with control, representing by decreased retinal ganglion cells (RGCs) and their axons, foveal abnormalities, and preserved peripheral retina except for the RGCs and their axons.

  10. Management strategy for congenital thumb differences in paediatric patients.

    PubMed

    2017-02-01

    Congenital thumb anomalies are common and have a major impact given the specific functional role of the thumb. They may occur alone or as part of a multiple congenital anomaly syndrome. The primary goal of surgical management is to improve or restore pincer grip. In patients with 'congenital' trigger thumb, the A1 pulley must be released if the interphalangeal joint remains in fixed flexion. Thumb duplication is generally managed by reconstruction of the thumb from the predominant (ulnar-based) digit; the accessory (radial-based) digit is excised after collection of its tissue components needed for the reconstruction programme. Thumb aplasia requires pollicisation of the index finger by island flap transfer of the second ray to give it the shape, position, and function of a thumb. Among patterns of digital hypoplasia, some require reconstruction of the existing thumb and others excision of the rudimentary thumb followed by pollicisation. In patients with aplasia of multiple hand digits, a toe transfer may be considered when there is no natural tendency to develop digital prehension at the hand.

  13. Management of pulmonary hypertension in infants with congenital diaphragmatic hernia.

    PubMed

    Gien, J; Kinsella, J P

    2016-06-01

    In infants with congenital diaphragmatic hernia (CDH), a posterolateral diaphragmatic defect results in herniation of abdominal contents into the chest and compression of the intrathoracic structures. In the most severe cases, hypoplasia of the ipsilateral and contralateral lungs, severe pulmonary hypertension (PH) and left ventricular (LV) hypoplasia/dysfunction all contribute to increased mortality. The management of PH in CDH is complicated by structural and functional changes in the heart, pulmonary vasculature, airways and lung parenchyma; consequently, determining optimal management strategies is challenging. Treatment of PH in patients with CDH changes as the underlying pathophysiology evolves in the days and weeks after birth. During the early transition, the use of pulmonary vasodilators is limited by LV structural and functional abnormalities, and pulmonary vasodilators such as inhaled nitric oxide (iNO) may have a limited role (for example, stabilization for extracorporeal membrane oxygenation (ECMO), treatment of marked preductal desaturation and treatment of PH as LV performance improves). In contrast, subacute treatment of PH in CDH with iNO has an important role in recurrent or persistent PH and potentially improves survival. Chronic PH and vascular abnormalities may persist into childhood in patients with CDH, contributing to late mortality. It is unclear how pulmonary vasodilator therapies, such as iNO, sildenafil and bosentan, will modulate late outcomes in CDH with late/chronic PH.

    1998-01-01

    The present study examined the presence of advanced glycosylation end products (AGEs) in lipofuscin present in the brain and adrenal gland of aging rats by immunohistochemistry using antibodies raised against AGEs. Lipofuscin identified as yellow to brown granules emitting bright yellow to orange autofluorescence with ultraviolet light were detected in cortical neurons, cerebellar Purkinje cells, and adrenal cells in the inner part of the zona reticularis. However, none of the antibodies visualized lipofuscin in these areas. The outer part of the zona reticularis contained yellow granules emitting a faint orange autofluorescence. These granules were immunostained by an antibody that reacted with AGEs structures unrelated to the carboxymethyllysine moiety. Newly formed adrenal cortical cells are thought to migrate from the outer layer to the inner layer of the zona reticularis. Therefore, our results suggest that glycosylation-related processes are involved in lipofuscinogenesis, at least in its early stage, in the adrenal zona reticularis.

    Although laparoscopic adrenalectomy has remained the standard of care for the treatment for adrenal tumors, percutaneous image-guided ablation therapy, such as chemical ablation, radiofrequency ablation, cryoablation, and microwave ablation, has been shown to be clinically useful in many nonsurgical candidates. Ablation therapy has been used to treat both functioning adenomas and malignant tumors, including primary adrenal carcinoma and metastasis. For patients with functioning adenomas, biochemical and symptomatic improvement is achieved in 96 to 100% after ablation; for patients with malignant adrenal neoplasms, however, the survival benefit from ablation therapy remains unclear, though good initial results have been reported. This article outlines the current role of ablation therapy for adrenal lesions, as well as identifying some of the technical considerations for this procedure.

    Congenital diaphragmatic hernia (CDH) occurs in 1 in 3,000 newborns. Mortality and morbidity are due to the amount of pulmonary hypoplasia (PH), the response on artificial ventilation and the presence of therapy-resistant pulmonary hypertension. The pathogenesis and etiology of CDH and its associated anomalies are still largely unknown despite all research efforts over the past years. Several animal models have been proposed to study CDH. In this review we compare surgical, pharmacological and transgenic models, and discuss their strengths and limitations to study PH.

  19. Metabolism of adrenal cholesterol in man

    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.

  20. Congenital Diaphragmatic Hernia with Delayed Presentation

    PubMed Central

    2016-01-01

    Congenital diaphragmatic hernia (CDH) is caused due to abnormal formation of the muscular parts of diaphragm. The incidence of CDH in common births ranges from 1/25000 to 1/30000. Pulmonary hypoplasia and pulmonary hypertension are factors that associate with the increase of mortality and morbidity due to CDH. We presented a 68-year-old Iranian woman with abdominal pain and tenderness in right upper quadrant who was diagnosed as having CDH. The disease was detected using chest X-ray and chest and abdomen sonography and confirmed with chest and abdomen CT scan with and without oral contrast. A defect was revealed in posterolateral right diaphragm with omentum and transverse colon herniated through it. Right posterolateral thoracotomy was performed to cure the disease. CT and CXR were the two useful methods in diagnosis of CDH in this patient, although CDH detection prior to surgery is too challenging because of rare cases and different types of CDH. In order to improve clinical cares in adult CDH patients, investigating more cases and long term follow-up are recommended. PMID:27872786

    Functioning black adrenal adenoma (BAA) rarely causes preclinical Cushing's syndrome (CS). In the present case, a 46-year-old Japanese Peruvian woman presented with left flank pain and hypertension. Abdominal computed tomography showed that she had a 15-mm in diameter, round, left adrenal adenoma. She had no physical features of CS, such as moon face, buffalo hump, truncal obesity, or purple striae. Endocrinological examination showed that the plasma adrenocorticotropic hormone (ACTH) level was below the detectable level, despite a serum cortisol level within the normal range. A normal cortisol circadian rhythm was not present. Dexamethasone (1 mg and 8 mg) suppression testing did not decrease serum cortisol levels to the reference levels. These findings were compatible with preclinical CS. The left adrenal adenoma was laparoscopically removed. Examination of the surgical specimen revealed unilateral double adrenal adenomas of the left adrenal gland, one of which was a BAA. The BAA measured 20 × 11 × 10 mm. Microscopically, the BAA showed proliferation of compact cells containing numerous brown-pigmented granules. There were also foci of myelolipomatous degenerative changes in the tumor. The compact cell zones remained in the adrenal cortex adjacent to the BAA showed atrophic change. These findings indicated that BAA appeared to have caused preclinical CS in this patient.

    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

    The adrenal glands are located superior to the kidneys and play an important role in the endocrine system. Each adrenal gland contains an outer cortex, responsible mainly for the secretion of androgens and corticosteroids, and an inner medulla, which secretes epinephrine and norepinephrine. Here, we review the anatomy of the adrenal glands and explain the current imaging modalities that are most useful for the assessment of the various conditions--both benign and malignant--that can affect these glands. As adrenal lesions are often identified incidentally on cross-sectional imaging performed for other reasons, the management of such adrenal 'incidentalomas' is also discussed. In many cases, adrenal lesions have distinctive imaging features that allow for a full characterization with noninvasive techniques. In some cases, invasive studies such as adrenal vein sampling or adrenal biopsy become necessary. This review should give the reader a wide overview of how various imaging techniques can be useful in the assessment of adrenal pathology.

    Goltz syndrome, caused by mutations in PORCN, is an X-linked dominant ectodermal dysplasia which is also known as focal dermal hypoplasia. This name is derived from the predominant pathologic skin findings of the syndrome. Nineteen Goltz-affected participants attended a multidisciplinary scientific and clinical conference convened by the National Foundation for Ectodermal Dysplasia which allowed further characterization of the features of this very rare condition. At birth, the affected areas of skin are typically erythematous and fragile. The hallmark cutaneous features, which vary widely due to mosacism and X-inactivation, include the previously described skin changes of asymmetric Blaschko-linear and reticulated atrophy, pigmentary changes, and telangectasias. Lipomatous changes and papillomas as characteristically defined were reported in the majority of patients. A newly recognized skin finding was progressive hyperpigmented freckling that occurred within the hypopigmented areas which were noted to be photosensitive. Many patients also had a pebbly texture to the central face, dorsal hands and feet. Punctate erosions within the atrophic areas and hypohidrosis were also common. Most had patchy alopecia and many had diffusely thin hair. Scanning electron microscopy of the hair shafts revealed abnormalities in the majority of participants with several different features identified, including atrophic hairs with reduced diameters, markedly flattened hairs as noted in cross-sectional views, trichorrhexis nodosa, pili torti, and pili trianguli et canaliculi. Nail changes included V-nicking and longitudinal ridging of the nail plate, in addition to micronychia. Early recognition of the dermatologic features, in addition to the variable but universal limb anomalies, of Goltz syndrome will allow early and accurate diagnosis without the need for extensive diagnostic studies, while also allowing for accurate prognosis and appropriate genetic counseling.

    Giant congenital melanocytic nevus is usually defined as a melanocytic lesion present at birth that will reach a diameter ≥ 20 cm in adulthood. Its incidence is estimated in <1:20,000 newborns. Despite its rarity, this lesion is important because it may associate with severe complications such as malignant melanoma, affect the central nervous system (neurocutaneous melanosis), and have major psychosocial impact on the patient and his family due to its unsightly appearance. Giant congenital melanocytic nevus generally presents as a brown lesion, with flat or mammilated surface, well-demarcated borders and hypertrichosis. Congenital melanocytic nevus is primarily a clinical diagnosis. However, congenital nevi are histologically distinguished from acquired nevi mainly by their larger size, the spread of the nevus cells to the deep layers of the skin and by their more varied architecture and morphology. Although giant congenital melanocytic nevus is recognized as a risk factor for the development of melanoma, the precise magnitude of this risk is still controversial. The estimated lifetime risk of developing melanoma varies from 5 to 10%. On account of these uncertainties and the size of the lesions, the management of giant congenital melanocytic nevus needs individualization. Treatment may include surgical and non-surgical procedures, psychological intervention and/or clinical follow-up, with special attention to changes in color, texture or on the surface of the lesion. The only absolute indication for surgery in giant congenital melanocytic nevus is the development of a malignant neoplasm on the lesion. PMID:24474093

    Congenital hypothyroidism is the most common neonatal metabolic disorder and results in severe neurodevelopmental impairment and infertility if untreated. Congenital hypothyroidism is usually sporadic but up to 2% of thyroid dysgenesis is familial, and congenital hypothyroidism caused by organification defects is often recessively inherited. The candidate genes associated with this genetically heterogeneous disorder form two main groups: those causing thyroid gland dysgenesis and those causing dyshormonogenesis. Genes associated with thyroid gland dysgenesis include the TSH receptor in non-syndromic congenital hypothyroidism, and Gsα and the thyroid transcription factors (TTF-1, TTF-2, and Pax-8), associated with different complex syndromes that include congenital hypothyroidism. Among those causing dyshormonogenesis, the thyroid peroxidase and thyroglobulin genes were initially described, and more recently PDS (Pendred syndrome), NIS (sodium iodide symporter), and THOX2 (thyroid oxidase 2) gene defects. There is also early evidence for a third group of congenital hypothyroid conditions associated with iodothyronine transporter defects associated with severe neurological sequelae. This review focuses on the genetic aspects of primary congenital hypothyroidism. PMID:15863666

    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.

    Relative adrenal insufficiency (RAI) is a common finding in cirrhotic patients with severe sepsis, and increased mortality. Its significance is unknown in stable conditions. The aim of this study was to evaluate the prevalence of RAI in stable cirrhotic patients at different stages of the disease. Also, the impact of RAI on the survival was evaluated and basal cortisol levels between plasma and saliva was correlated in control subjects and cirrhotic patients. Forty seven ambulatory patients and 16 control subjects were studied. RAI was defined as a serum cortisol increase of less than 9 υg/dl from baseline after the stimulation with 250 mg of synthetic ACTH. Twenty two had Child-Pugh = 8 and 25 = 9. The prevalence of RAI in patients with stable cirrhosis was 22%. A higher incidence of RAI was observed in patients with a Child-Pugh = 9 (8/32) than in those with = 8 (3/13, p < 0.05). A correlation between salivary cortisol and basal plasma cortisol (r = 0.6, p < 0.0004) was observed. Finally, survival at 1 year (97%) and 3 years (91%) was significantly higher without RAI than those who developed this complication (79% and 51%, p < 0.05, respectively). In summary, the prevalence of RAI is frequent in patients with stable cirrhosis and that it is related to the severity of liver diseaseand increased mortality.

    Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Sarcomatoid adrenal carcinoma is even more aggressive type of ACC. Bilateral malignant adrenal tumors are extremely rare except for those that represent metastasis from an extra-adrenal organ. Here we report a 53-year-old woman who presented with abdominal pain and weight loss. Abdominal computed tomography revealed bilateral adrenal masses and a mass in her liver. Surgical specimens showed pleomorphic tumor cells with epithelial and spindle cell morphology and immunohistochemical staining was compatible with sarcomatoid carcinoma. Sarcomatoid adrenal carcinoma should be kept in mind during the management of bilateral adrenal masses. PMID:28097033

    The development of radiolabeled cholesterols in 1969 as precursors of adrenocortical steroid production allowed the first noninvasive imaging of the adrenal cortices. FDA-NDA approval in 1984 should allow routine use of these agents in most hospitals. NP-59 is most commonly used in the diagnosis and management of Cushing syndrome; the second most common use is in the diagnosis of primary aldosteronism. It is also helpful in the differential diagnosis of adrenal and ovarian hyperandrogenism and hirsutism, and is the only noninvasive method of detecting unilateral adrenocortical hypofunction. The newest and most popular use is in the differential diagnosis of asymptomatic masses in the region of the adrenal gland discovered incidentally with CT scan (incidentalomas). In this situation, the NP-59 scan can define whether the tumor is in the adrenal gland and if it is functional or nonfunctional. The authors believe that, in the future, radiolabeled enzyme inhibitors might offer better diagnostic imaging of the adrenal cortex, although these agents will probably not be available for routine use for some time. The development of a radioiodinated guanethidine analog, /sup 131/I-MIBG, has allowed differentiation of normal adrenal medullary function from bilateral adrenal medullary hyperplasia before the development of hypertension or tachycardia, diagnostic increases in plasma or urinary catecholamines, or abnormal CT scans. The search for a pheochromocytoma should begin with /sup 131/I-MIBG scintigraphy. While over 90% of primary pheochromocytomas occur in the abdomen, neither a survey of the abdomen nor the finding of a single tumor should conclude the search.

    Goldenhar syndrome (GS), a rare condition, occurring due to defect in development of first and second branchial arches, is characterized by a combination of various anomalies involving face, eyes, ears, vertebrae, heart, and lungs. The etiology of GS is not fully known, although various hypotheses have been proposed along with its genetic association and many other causes. Facial asymmetry and hypoplasia of the mandible are characteristic features of GS along with microtia and preauricular appendages and pits. Dextrocardia or pulmonary hypoplasia in GS has previously been reported separately. We report a 7-year-old female child of GS with combination of anomalies, dextrocardia, and pulmonary hypoplasia, which is a rare association. PMID:28377826

    Midface hypoplasia or retrusion remains a persistent feature of syndromic craniosynostosis years after successful treatment of the cranium. Although expansion of the cranial vault in infancy by traditional fronto-orbital advancement, posterior expansion, or both, can treat the immediate intracranial constriction, midface hypoplasia and its stigmata of exorbitism, sleep apnea, central face concavity, and malocclusion remain suboptimally treated. Initial enthusiasm for the procedures was tempered due to a high rate of infectious complications; timing and indications for surgery continue to stir controversy. During the last decade renewed interest with the monobloc and facial bipartition procedure using distraction osteogenesis with either an internal or external distraction system has decreased morbidity significantly. These procedures have re-emerged as powerful and comprehensive tools in the treatment of syndromic midface hypoplasia. PMID:26417208

    Cartilage-hair hypoplasia is a rare metaphyseal chondrodysplasia characterized by diverse clinical manifestations and a high incidence of Hirschsprung disease. We present a male patient with cartilage-hair hypoplasia associated with severe intestinal obstruction. Genetic analysis of ribonuclease mitochondrial RNA-processing complex gene identified compound heterozygous mutations consisted with previously reported mutations: n.-14_3dupGAAGCTGAGGACGTGGT and n.183G > T. First, we considered that intestinal obstruction was due to an extensive type of Hirschsprung disease, but it was later confirmed as isolated hypoganglionosis. Isolated hypoganglionosis is rare and its therapeutic strategies are not well established. In cases of cartilage-hair hypoplasia associated with severe intestinal obstruction, the differential diagnosis of not only Hirschsprung disease, but also isolated hypoganglionosis, should be considered.

    The adrenal is the most common toxicological target organ in the endocrine system in vivo and yet it is neglected in regulatory endocrine disruption screening and testing. There has been a recent marked increase in interest in adrenal toxicity, but there are no standardised approaches for assessment. Consequently, a strategy is proposed to evaluate adrenocortical toxicity. Human adrenal conditions are reviewed and adrenocortical suppression, known to have been iatrogenically induced leading to Addisonian crisis and death, is identified as the toxicological hazard of most concern. The consequences of inhibition of key steroidogenic enzymes and the possible toxicological modulation of other adrenal conditions are also highlighted. The proposed strategy involves an in vivo rodent adrenal competency test based on ACTH challenge to specifically examine adrenocortical suppression. The H295R human adrenocortical carcinoma cell line is also proposed to identify molecular targets, and is useful for measuring steroids, enzymes or gene expression. Hypothalamo-pituitary-adrenal endocrinology relevant to rodent and human toxicology is reviewed (with an emphasis on multi-endocrine axis effects on the adrenal and also how the adrenal affects a variety of other hormones) and the endocrinology of the H295R cell line is also described. Chemicals known to induce adrenocortical toxicity are reviewed and over 60 examples of compounds and their confirmed steroidogenic targets are presented, with much of this work published very recently using H295R cell systems. In proposing a strategy for adrenocortical toxicity assessment, the outlined techniques will provide hazard assessment data but it will be regulatory agencies that must consider the significance of such data in risk extrapolation models. The cases of etomindate and aminoglutethimide induced adrenal suppression are clearly documented examples of iatrogenic adrenal toxicity in humans. Environmentally, sentinel species, such as

    Endogenous glucocorticoid-induced thymic involution is generally considered to be an important finding for determining child abuse. The present study investigated the weight of the thymus and the adrenal glands in elder abuse cases to identify a potential marker for elder abuse. There was no significant difference in the thymus and the adrenal weight between elder abuse and control cases. However, the elder abuse cases in which the duration of abuse was less than 3 months showed a significant increase in the adrenal weight in comparison to control cases. In such cases, histopathological findings showed a loss of intracellular light granules from the zona fasciculata, which might indicate a loss of cholesterol due to the overproduction of glucocorticoid. These results might imply that the elderly, who were maltreated for less than 3 months, were in the early phase of a long-term stress state during which stress-induced overproduction of glucocorticoid was observed in adrenal glands as indicated by Selye. Our results suggest that an increase in adrenal weight may be a potential marker for elder abuse of relatively short periods, especially less than a few months.

    A discrete area of defective enamel formation that appears on the labial surface of the crowns of deciduous canine teeth has been described in both recent and prehistoric human populations, with reported frequencies varying from 1 to 45 per cent. Suggestions about the aetiology of this localized hypoplasia range from genotypic factors to environmental conditions and systemic effects. The major aims of this study were to describe the frequency of occurrence and pattern of expression of the lesion in Australian Aboriginal and Caucasian ethnic groups, and to clarify the role of genetic factors by examining a sample of twins. The study sample consisted of dental casts of 181 pairs of Australian Caucasian twins, 215 Aborigines and 122 Caucasian singletons, together with 253 extracted deciduous canines. Examination of dental casts and extracted teeth was undertaken under 2x magnification with emphasis being placed upon location and expression of the lesion. The defect was observed in 49 per cent of twins and 44 per cent of Aborigines, but only 36 per cent of singletons. The percentages of affected teeth in each group were: 18 per cent in twins, 17 per cent in Aborigines and 13 per cent in Caucasians. A significant proportion of the defects occurred on the mesial aspect of the labial surface, in the middle area incisocervically, with the majority in the lower jaw. A number of significant differences in frequency were observed between groups, sexes, arches and sides. The results confirm some of the findings of previous studies, but also suggest that none of environmental, genetic or systemic factors can be ruled out as being involved in aetiology of the defect. The higher incidence of the lesion occurring on the mesial aspect of the labial surface is suggestive of physical trauma. Also, the vulnerability of the prominent developing mandibular canine, with its thin or missing labial covering of bone, would be expected to lead to higher prevalence of the lesion in the lower

    Congenital syphilis has been diagnosed very seldom in ancient populations. The case that we examined comes from San Jeronimo's Church (17th and 18th centuries AD; Mexico City). Coffin 43 contained an incomplete skeleton of an approximately 2-year-old infant. The pathological lesions of this skeleton include bilateral osteochondritis, diaphyseal osteomyelitis, and osteitis and/or periostitis on the long bones. The radiographic appearance depicts symmetrical osteomyelitic foci, particularly at the proximal extremity of both tibiae (Wimberger's sign). The skull exhibits hydrocephaly and periosteal changes on the vault, and the unerupted upper incisors evince dental hypoplasia and other pathological alterations reminiscent of Hutchinson's incisors. All these features strongly suggest a case of early congenital syphilis.

    Cone reconstruction for tricuspid valve repair has revolutionized the surgical treatment of Ebstein anomaly. We present the case of a 58-year-old woman with atypical Ebstein anomaly and right ventricular apical hypoplasia who was spared from palliative shunt physiology by our use of cone reconstruction. Compared with other techniques, cone reconstruction of the tricuspid valve more closely replicates normal valvular anatomy and function. This surgical procedure can be applied to many anatomic variations of Ebstein anomaly, as in our patient's apparently unique instance of atypical Ebstein anomaly with right ventricular apical hypoplasia.

    Seckel syndrome (SCKL) [OMIM Entry 210600] is a rare, autosomal recessive syndrome, characterized by severe intrauterine and postnatal growth retardation, microcephaly, mental retardation, and typical facial appearance with beaklike protrusion of the midface (bird-headed). Associated findings may include limb anomalies, dislocation of femoral heads, scoliosis, and gastrointestinal malformation. A 14-year-old boy is presented with brain hypoplasia, pachygyria, hydrocephaly, enamel hypoplasia and root dysplasia in the temporary dentition, and oligodontia, severe microdontia, and delayed eruption of the permanent dentition. The association of SCKL with the above unusual dental findings may represent a new phenotype.

    We describe an extremely rare combination of tetralogy of Fallot (TOF), right-sided cervical aortic arch with long-segment hypoplasia, and other vascular anomalies. A two-stage surgical approach included aortic arch reconstruction followed by right ventricular muscle bundle division and ventricular septal defect closure a few weeks later. The initial clinical presentation, perioperative course, and imaging studies are presented along with a review of the relevant literature. This is the first report of successful neonatal repair of TOF with long-segment hypoplasia of the aorta.

    Five painted storks were treated with fenbendazole for 5 days for internal parasitism. Four birds died following treatment. Profound heteropenia was a consistent finding in all samples evaluated; additionally, the 1 surviving bird had progressive anemia. Consistent necropsy findings in the 4 birds that died were small intestinal crypt cell necrosis and severe bone marrow depletion and necrosis. Fenbendazole has been associated with bone marrow hypoplasia and enteric damage in mammals and other species of birds. The dosages of fenbendazole used in birds are often substantially higher than those recommended for mammals, which may contribute to bone marrow hypoplasia and intestinal crypt cell necrosis associated with fenbendazole administration in birds.

    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 malignant 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.

    Image-guided biopsy is a safe and well-established technique that is familiar to most interventional radiologists (IRs). Improvements in image-guidance, biopsy tools and biopsy techniques now routinely allow for safe biopsy of renal and adrenal lesions which traditionally were considered difficult to reach or technically challenging. Image-guided biopsy is used to establish the definitive tissue diagnosis in adrenal mass lesions that can not be fully characterized with imaging or laboratory tests alone. It is also used to establish definitive diagnosis in some cases of renal parenchymal disease and has an expanding role in diagnosis and characterization of renal masses prior to treatment. Although basic principles and techniques for image-guided needle biopsy are similar regardless of organ, this paper will highlight some technical considerations, indications and complications which are unique to the adrenal gland and kidney because of their anatomic location and physiologic features.

  16. Adrenal Hemorrhage in Neonates: Unusual Presentation.

    Adrenal hemorrhage (AH) is a relatively uncommon condition in newborns. It may be asymptomatic or may present with flank abdominal mass, anemia, jaundice, or rarely as scrotal bruising or hematoma. We report two cases of AH in neonates; the first presented with scrotal hematoma and the second with adrenal mass associated with hypertension and oliguria, primarily secondary to coincidental renal vein thrombosis. Diagnosis was confirmed by abdominal ultrasound. Patients were managed conservatively with clinical observation and by following hemoglobin and bilirubin levels closely. Both infants were discharged without surgical intervention after several days in the hospital. Clinicians should consider AH when a newborn presents with scrotal bruising or hematoma, unexplained anemia, unexplained jaundice, or flank abdominal mass. Timely ultrasonographic evaluation of both adrenal glands and testes in neonates with scrotal hematoma may spare infants from unnecessary surgical intervention because scrotal hematoma often raises the suspicion of testicular torsion.

    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. PMID:27609733

    Background and Objectives: Laparoscopy has acquired an unquestionable position in surgical practice as a diagnostic and operative tool. Recently, the laparoscopic approach has become a valuable option for adrenalectomy. This paper reports, in detail, our experience of laparoscopic adrenalectomy performed for adrenal tumors. Methods: We performed 12 laparoscopic adrenalectomies from October 29, 1997 to October 31, 1998. The technique of laparoscopic adrenalectomy is described thoroughly in all relevant details for either left or right-sided adrenal lesions. Results: The presented technique of laparoscopic adrenalectomy in all 12 cases provided good and relatively simple exposure of the immediate operative area. All relevant vascular elements were safely controlled, adrenal tumors could be successfully removed, and adequate hemostasis was achieved. No intraoperative or postoperative complications were observed. Conclusions: Laparoscopic adrenalectomy is a safe alternative to open surgery and is preferred for most patients because of shorter postoperative hospital stay and less postoperative discomfort.

    Data are limited on the localization of Ga-67 in primary or metastatic adrenal cortical carcinoma. We report the localization of Ga-67 to pathologically confirmed adrenal cortical carcinoma metastatic to the lung. A review of the literature revealed four patients have previously been reported to have metastatic adrenal cortical carcinoma detected on Ga-67 scan. Gallium imaging may be useful in the evaluation of patients with adrenal cortical carcinoma. SPECT imaging should further improve lesion resolution and localization.
