    Smith-Lemli-Opitz syndrome (SLOS) is a multiple congenital malformation/intellectual disability syndrome, with clinical characteristics encompassing a wide spectrum and great variability. Elucidation of the biochemical and molecular genetic basis for the autosomal recessively inherited SLOS, specifically, understanding SLOS as a cholesterol deficiency syndrome caused by mutations in DHCR7, opened up enormous possibilities for therapeutic intervention. When cholesterol was discovered to be the activator of sonic hedgehog, cholesterol deficiency with inactivation of this developmental patterning gene was thought to be the cause of SLOS malformations, yet this explanation is overly simplistic. Still, despite these important research breakthroughs, there is no proven treatment for SLOS. Better animal models are needed to allow potential treatment testing and the study of disease pathophysiology, which is incompletely understood. Creation of human cellular models will surely be useful, especially models of brain cells. In vivo human studies are essential as well. There have only been limited natural history studies of SLOS to date. Biomarker development will be critical in facilitating clinical trials in this rare condition, since clinical phenotype may change over many years. Additional research in these and other areas is critical if we are to make headway towards ameloriating the effects of this devastating condition. PMID:21777499

    Smith-Lemli-Opitz syndrome is an autosomal recessive mental retardation and multiple malformation syndrome caused by deficiency of the 7-dehydrocholesterol reductase, the enzyme catalyzing the last step in cholesterol biosynthesis. The authors summarize the pathophysiology, epidemiology, clinical picture, diagnostics and therapy of the disease based on a review of the international literature. Since 2004, fourteen patients have been diagnosed with Smith-Lemli-Opitz syndrome in Hungary, which suggests an underdiagnosis of the disease based upon estimated incidence data. Due to deficiency of the 7-dehydrocholesterol reductase, serum cholesterol concentration is low and 7-dehydrocholesterol concentration is elevated in blood and tissues; the latter being highly specific for the syndrome. Detection of disease-causing mutations makes the prenatal diagnosis possible. The clinical spectrum is wide, the most common symptom is syndactyly of the second and third toes. Standard therapy is cholesterol supplementation. Recent publications suggest that oxidative compounds of 7-dehydrocholesterol may play a role in the pathophysiology of the disease as well.

    We describe a rapid and sensitive method involving time-of-flight secondary-ion mass spectrometry (TOF-SIMS) for specific laboratory diagnosis of the Smith-Lemli-Opitz syndrome, which is characterized by massive (approximately 1000-fold) accumulation of the biosynthetic cholesterol precursor 7-dehydrocholesterol. Minute amounts of blood (1-50 microL) were extracted with n-hexane, and aliquots were analyzed by TOF-SIMS. 7-Dehydrocholesterol and its isomers were detected at 491.3 mass units ([M + 107Ag]+) and cholesterol at 495.3 mass units ([M + 109Ag]+). Quantitation of 7-dehydrocholesterol and cholesterol was achieved after saponification and addition of stigmasterol as internal standard. Whereas 7-dehydrocholesterol and isomeric dehydrocholesterol were not detectable in controls, the patients revealed concentrations ranging between 0.84 and 1.25 mmol/L. Comparison with results obtained by gas chromatography indicated that quantitation by TOF-SIMS yielded the sum of 7-dehydrocholesterol, isomeric dehydrocholesterol II, and sterol III, the latter two also being increased in the patients. Consistent with quantitation by gas chromatography, the cholesterol concentrations in the patients ranged between 1.54 and 2.12 mmol/L (controls: 6.10 +/- 1.37 mmol/L). PMID:7720244

    Smith-Lemli-Opitz syndrome (SLOS) is a rare multiple congenital anomaly neurodevelopmental syndrome of impaired cholesterol synthesis. Growth restriction and developmental delay are very common clinical manifestations of SLOS. The degree, etiology, and consequences of growth restriction in SLOS remain an area of limited knowledge to the scientific community. There have been no studies describing the growth parameters and providing reference growth charts for individuals with SLOS. Our longitudinal data from 78 patients between the ages of 0.1 and 16 years with SLOS show a growth restriction of about two standard deviations below the Centers for Disease Control (CDC) norms for age. This study represents comprehensive anthropometric data from the largest cohort available, and proposes growth charts for widespread use in the management and study of individuals with SLOS.

    The Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive multiple congenital malformation syndrome caused by dehydrocholesterol reductase deficiency. The diagnosis is confirmed by high 7- and secondarily 8-dehydrocholesterol levels in plasma and tissues and/or by detection of biallelic mutations in the DHCR7 gene. The phenotypic spectrum of SLOS is broad, ranging from a mild phenotype combining subtle physical anomalies with behavioral and learning problems, to a perinatally lethal multiple malformations syndrome. The fetal phenotype of SLOS has been poorly described in the literature. We report a series of 10 fetuses with molecularly proven SLOS. Even in young fetuses, the facial dysmorphism appears characteristic. Genital abnormalities are rare in 46,XX subjects. Gonadal differentiation appears histologically normal and in agreement with the chromosomal sex, contrary to what has been previously stated. We observed some previously unreported anomalies: ulnar hypoplasia, vertebral segmentation anomalies, congenital pulmonary adenomatoid malformation, fused lungs, gastroschisis, holomyelia and hypothalamic hamartoma. This latter malformation proves that SLOS phenotypically overlaps with Pallister-Hall syndrome which remains clinically a major differential diagnosis of SLOS. PMID:22226660

    We reviewed 215 patients (59 new, 156 from the literature) with Smith-Lemli-Opitz syndrome (SLOS), and found that 95 (44%) had a cardiovascular malformation (CVM). Classifying CVMs by disordered embryonic mechanisms, there were 5 (5.3%) class I (ectomesenchymal tissue migration abnormalities), 56 (58.9%) class II (abnormal intracardiac blood flow), 25 (26.3%) class IV (abnormal extracellular matrix), and 5 (5.3%) class V (abnormal targeted growth). Comparing the frequencies of individual CVMs in this series with a control group (the Baltimore-Washington Infant Study), there were 6 individual CVMs which showed a significant difference from expected values. When frequencies of CVMs in SLOS were analyzed by mechanistic class, classes IV and V were significantly more frequent, and class I significantly less frequent, than the control group. Although CVMs in SLOS display mechanistic heterogeneity, with an overall predominance of class II CVMs, the developmental error appears to favor alteration of the cardiovascular developmental mechanisms underlying atrioventricular canal and anomalous pulmonary venous return. This information should assist the clinical geneticist evaluating a patient with possible SLOS, and should suggest research direction for the mechanisms responsible for the SLOS phenotype. 102 refs., 1 fig., 7 tabs.

    Smith-Lemli-Opitz syndrome (SLOS), caused by 7-dehydrocholesterol-reductase (DHCR7) deficiency, shows variable severity independent of DHCR7 genotype. To test whether peroxisomes are involved in alternative cholesterol synthesis, we used [1-{sup 14}C]C24:0 for peroxisomal {beta}-oxidation to generate [1-{sup 14}C]acetyl-CoA as cholesterol precursor inside peroxisomes. The HMG-CoA reductase inhibitor lovastatin suppressed cholesterol synthesis from [2-{sup 14}C]acetate and [1-{sup 14}C]C8:0 but not from [1-{sup 14}C]C24:0, implicating a peroxisomal, lovastatin-resistant HMG-CoA reductase. In SLOS fibroblasts lacking DHCR7 activity, no cholesterol was formed from [1-{sup 14}C]C24:0-derived [1-{sup 14}C]acetyl-CoA, indicating that the alternative peroxisomal pathway also requires this enzyme. Our results implicate peroxisomes in cholesterol biosynthesis but provide no link to phenotypic variation in SLOS.

    Smith-Lemli-Opitz syndrome (SLOS) is a metabolic disorder in which an error in cholesterol biosynthesis results in congenital anomalies/mental deficits. The results of our previous newborn screening, based on the carrier frequency of the two most common SLOS-causing mutations in Poland (p.W151X and p.V326L), would make SLOS one of the most frequent recessive disorders in our country (with an incidence of 1:2,300 - 1:3,937). This prompted us to carry out a 3-year (2006-2008) national surveillance program in which about 2,000 physicians were asked to identify potential SLOS patients pre- and postnatally based on clinical identification forms. The incidence of SLOS in Poland was estimated to be from 1:60,941 to 1:105,395 (1: 83,168 22,227) live births, and its 3-year prevalence 1:866,273 16,242. The mean carrier frequency was calculated to be from 1:123 to 1:165. The notable discrepancy between our previous carrier newborn screening and these prospective data may result from reduced fertility in SLOS carriers, intrauterine death of affected fetuses, or underdiagnosis in postnatal life. Since we did not notice significant data supporting the first two aspects, our study may support the suggestion that screening for the most frequent DHCR7 alleles does not reflect the true disease rates in the Polish population. Hence, further studies in which maternal urinary steroids (7-dehydroestriol/estriol and 8-dehydropregnanetriol/pregnanetriol ratios) would serve as screening markers in early pregnancies may be justified.

    Smith-Lemli-Opitz syndrome is a frequently occurring autosomal recessive developmental disorder characterized by facial dysmorphisms, mental retardation, and multiple congenital anomalies. Biochemically, the disorder is caused by deficient activity of 7-dehydrocholesterol reductase, which catalyzes the final step in the cholesterol-biosynthesis pathway-that is, the reduction of the Delta7 double bond of 7-dehydrocholesterol to produce cholesterol. We identified a partial transcript coding for human 7-dehydrocholesterol reductase by searching the database of expressed sequence tags with the amino acid sequence for the Arabidopsis thaliana sterol Delta7-reductase and isolated the remaining 5' sequence by the "rapid amplification of cDNA ends" method, or 5'-RACE. The cDNA has an open reading frame of 1,425 bp coding for a polypeptide of 475 amino acids with a calculated molecular weight of 54.5 kD. Heterologous expression of the cDNA in the yeast Saccharomyces cerevisiae confirmed that it codes for 7-dehydrocholesterol reductase. Chromosomal mapping experiments localized the gene to chromosome 11q13. Sequence analysis of fibroblast 7-dehydrocholesterol reductase cDNA from three patients with Smith-Lemli-Opitz syndrome revealed distinct mutations, including a 134-bp insertion and three different point mutations, each of which was heterozygous in cDNA from the respective parents. Our data demonstrate that Smith-Lemli-Opitz syndrome is caused by mutations in the gene coding for 7-dehydrocholesterol reductase. PMID:9683613

    Thirty years after its clinical delineation in humans and its teratologic simulation in rats, a Garrodian error of metabolism was discovered in the autosomal recessive RSH/SLO syndrome, namely defective conversion of 7-dehydrocholesterol to cholesterol due to the mutant 7-dehydrocholesterol reductase. This opened the door to the study of several other defects of sterol biosynthesis in humans and the creation of animal "models." The gross discrepancy between expected and observed birth prevalence suggests high embryolethality. The discovery of the role of cholesterol in the synthesis of the morphogen sonic hedgehog has greatly advanced our understanding of mammalian development. PMID:23059855

    We report on the hypothalamic-pituitary-gonadal function in 2 male infants with the Smith-Lemli-Opitz (SLO or RSH) syndrome. Both infants had abnormal external genitalia. Basal and LHRH stimulated plasma gonadotropins were normal for age (1 month). Plasma testosterone, androstenedione, and dehydroepiandrosterone sulfate were normal for age and sex. Some forms of congenital adrenal hyperplasia (17,20-desmolase deficiency, 17 alpha-hydroxylase deficiency, and 3 beta-hydroxysteroid dehydrogenase deficiency) were ruled out by hormonal studies. The endocrinological findings indicate a normal hypothalamic-pituitary-gonadal function and a normal adrenal steroid biosynthesis in these 2 patients. A partial androgen receptor defect causing the genital malformations seems possible in one patient. Whether 5 alpha-reductase deficiency is the cause of the male pseudohermaphroditism in SLO syndrome remains the subject of future studies. PMID:1605242

    Routine ultrasound examination at 11 weeks of gestation in a woman with no family history of genetic disease demonstrated increased accumulation of fluid in the fetal nuchal region. In view of the association of this defect with chromosomal abnormalities, fetal karyotyping was performed by chorion villus sampling and this demonstrated a normal 46,XY karyotype. Subsequent scans showed resolution of the nuchal fluid, and at the 20-week scan the fetal genitalia appeared to be female. Fetal blood sampling confirmed a normal male karyotype and fetoscopy confirmed the presence of female external genitalia. The parents elected to terminate the pregnancy, and postmortem findings were indicative of Smith-Lemli-Opitz syndrome. This was confirmed by the finding of increased levels of 7-dehydrocholesterol in cultured skin fibroblasts. 11 refs., 2 figs., 1 tab.

    Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder caused by reduced activity of 7-dehydrocholesterol reductase, resulting in an increased concentrations of 7-dehydrocholesterol and 8-dehydrocholesterol in body fluids and tissues. Phenotypically it is characterized by wide range of abnormalities, from mild to lethal forms what causes difficulties in its clinical diagnostics. To further delineate the physical spectrum of the mild form of Smith-Lemli-Opitz syndrome, especially with regard to genotype-phenotype correlation, we describe 5 Polish patients with mild phenotype (one with novel mutation in DHCR7 gene and four published before) and analyze 18 other cases from the literature. As the conclusion we give recommendation for tests toward SLOS in cases with "idiopathic" intellectual impairment and/or behavioral anomalies, as well as in biochemically doubtful but clinically fitting cases with overall gestalt and history of this syndrome.

    Photosensitivity has recently been reported as a feature of the Smith-Lemli-Opitz syndrome (SLO). The aim of this study was to establish the photobiological features of this disorder and to examine the hypothesis that the photosensitivity is caused by the high levels of 7-dehydrocholesterol found in SLO. All known cases of SLO in the U.K. were reviewed and clinical details of photosensitivity were recorded in detail. The action spectrum of the photosensitive eruption was defined by monochromator light testing. Thirteen of the 23 subjects (57%) had severe photosensitivity, and in 10 there was no photosensitivity. No correlation was identified between levels of 7-dehydrocholesterol and severity of photosensitivity, suggesting that the photosensitivity in SLO is not caused by a direct phototoxic effect mediated by 7-dehydrocholesterol. A novel pattern of photosensitivity was observed, with onset of a sunburn-like erythema on sun-exposed skin within minutes of sun exposure, which persisted in most cases for up to 24-48 h before fading. Monochromator light testing in three subjects showed an ultraviolet (UV) A-mediated photosensitivity eruption with greatest photosensitivity at 350 nm. Photosensitivity is a common and prominent feature of SLO and appears to be UVA-mediated. Elucidation of its biochemical basis may provide insight into normal cutaneous protective mechanisms against UVA-induced photodamage, and also sun sensitivity in general. PMID:10583043

    Introduction Smith-Lemli-Opitz Syndrome (SLOS) is a malformation syndrome inherited in an autosomal recessive fashion. It is due to a metabolic defect in the conversion of 7-dehydrocholesterol to cholesterol, which leads to an accumulation of 7-dehydrocholesterol and frequently a deficiency of cholesterol. The syndrome is characterized by typical dysmorphic facial features, multiple malformations, and intellectual disability. Areas covered In this paper we provide an overview of the clinical phenotype and discuss how the manifestations of the syndrome vary depending on the age of the patients. We then explore the underlying biochemical defect and pathophysiological alterations that may contribute to the many disease manifestations. Subsequently we explore the epidemiology and succinctly discuss population genetics as they relate to SLOS. The next section presents the diagnostic possibilities. Thereafter, the treatment and management as is standard of care are presented. Expert opinion Even though the knowledge of the underlying molecular mutations and the biochemical alterations is being rapidly accumulated, there is currently no efficacious therapy addressing neurological dysfunction. We discuss the difficulty of treating this disorder, which manifests as a combination of a malformation syndrome and an inborn error of metabolism. A very important factor in developing new therapies is the need to rigorously establish efficacy in controlled trials. PMID:25734025

    Smith-Lemli-Opitz syndrome (SLOS) is a multiple congenital anomaly/mental retardation syndrome, with features including toe syndactyly, genital anomalies, unusual facies, and occasional organ malformations. The gene(s) for this autosomal recessive disorder has not been mapped. Recent biochemical studies suggest that the defect may involve the penultimate step in cholesterol synthesis, as patients have low serum cholesterol and increased 7-dehydrocholesterol (7-DHC) levels. However, the enzyme putatively involved (7-DHC reductase) has not been isolated. We identified an SLOS patient with a de novo balanced chromosome translocation [t(7;20)(q32.1;q13.2)], and we propose that the translocation interrupts one of the patient`s SLOS alleles. We are pursuing positional cloning to identify the SLOS gene. Using fluorescence in situ hybridization (FISH), we recently identified a chromosome 7 yeast artificial chromosome (YAC) that spans the breakpoint and places it onto physical and genetic maps. We are in the process of narrowing this region via overlapping YACs and YAC subclones, from which we will isolate candidate cDNAs. Any candidate gene disrupted by the translocation and mutated on the other allele will be proven to be the SLOS gene. Functional analysis of an SLOS cDNA may also determine its relationship to cholesterol metabolism and the observed biochemical abnormalities.

    Smith-Lemli-Opitz syndrome (SLOS) is a congenital, autosomal recessive metabolic and developmental disorder caused by mutations in the enzyme which catalyzes the reduction of 7-dehydrocholesterol (7DHC) to cholesterol. Herein we show that dermal fibroblasts obtained from SLOS children display increased basal levels of LC3B-II, the hallmark protein signifying increased autophagy. The elevated LC3B-II is accompanied by increased beclin-1 and cellular autophagosome content. We also show that the LC3B-II concentration in SLOS cells is directly proportional to the cellular concentration of 7DHC, suggesting that the increased autophagy is caused by 7DHC accumulation secondary to defective DHCR7. Further, the increased basal LC3B-II levels were decreased significantly by pretreating the cells with antioxidants implicating a role for oxidative stress in elevating autophagy in SLOS cells. Considering the possible source of oxidative stress, we examined mitochondrial function in the SLOS cells using JC-1 assay and found significant mitochondrial dysfunction compared to mitochondria in control cells. In addition, the levels of PINK1 which targets dysfunctional mitochondria for removal by the autophagic pathway are elevated in SLOS cells, consistent with mitochondrial dysfunction as a stimulant of mitophagy in SLOS. This suggests the increase in autophagic activity may be protective, i.e., to remove dysfunctional mitochondria. Taken together, these studies are consistent with a role for mitochondrial dysfunction leading to increased autophagy in SLOS pathophysiology. PMID:25405082

    Smith-Lemli-Opitz syndrome (SLOS) is a common autosomal-recessive disorder that results from mutations in the gene encoding the cholesterol biosynthetic enzyme 7-dehydrocholesterol reductase (DHCR7). Impaired DHCR7 function is associated with a spectrum of congenital malformations, intellectual impairment, epileptiform activity and autism spectrum disorder. Biochemically, there is a deficit in cholesterol and an accumulation of its metabolic precursor 7-dehydrocholesterol (7DHC) in developing tissues. Morphological abnormalities in SLOS resemble those seen in congenital Sonic Hedgehog (SHH)-deficient conditions, leading to the proposal that the pathogenesis of SLOS is mediated by aberrant SHH signalling. SHH signalling is transduced through the transmembrane protein Smoothened (SMO), which localizes to the primary cilium of a cell on activation and is both positively and negatively regulated by sterol molecules derived from cholesterol biosynthesis. One proposed mechanism of SLOS involves SMO dysregulation by altered sterol levels, but the salient sterol species has not been identified. Here, we clarify the relationship between disrupted cholesterol metabolism and reduced SHH signalling in SLOS by modelling the disorder in vitro. Our results indicate that a deficit in cholesterol, as opposed to an accumulation of 7DHC, impairs SMO activation and its localization to the primary cilium. PMID:26685159

    Smith-Lemli-Opitz (SLOS), or RSH syndrome, is an autosomal recessive deficiency of 7-dehydrocholesterol reductase (DHCR7) resulting in an accumulation of 7- and 8-dehydrocholesterol (7- and 8-DHC) in tissues and body fluids. At birth patients have variable malformations of CNS, heart, kidney, genitalia, and limbs, which may be life-limiting. In later course, psychomotor and mental retardation and behavior abnormalities become evident. Prenatally SLOS can be suspected on the basis of malformations and intrauterine growth retardation (IUGR) in prenatal ultrasonography and reduced maternal free estriol in serum. The diagnosis is confirmed by sterol analysis in a chorionic villus biopsy or amniotic fluid (AF). In this study, we evaluated the predictive value of the above mentioned criteria in combination with family history by quantification of sterols in AF in pregnancies with either a family history, ultrasonographical abnormalities typical for SLOS, or reduced maternal serum unconjugated estriol (MSuE3). The relative frequency of SLOS in fetuses with an affected sibling was 0.23, as to be expected for an autosomal recessive disease. The probability for SLOS was <0.6% when neither an affected sib nor more than one typical SLOS malformation was present. For safety reasons and for cost-effectiveness we recommend careful evaluation of history, MSuE3, and clinical presentation before determining sterols in AF. PMID:23532938

    Objective To quantitatively evaluate feeding impairment in children with Smith-Lemli-Opitz Syndrome (SLOS) and to correlate feeding impairment with clinical and biochemical indices of disease severity. Study design Subjects were 26 children with SLOS, 0.4 to 19 years age. Clinical severity was measured using an existing scoring system. We created a tool to quantitatively evaluate feeding. Plasma sterol concentrations were measured, and statistical associations (correlations) with feeding scores were calculated. Results Oral hypo- or hypersensitivity, adverse behaviors, and risk for dysphagia were seen in ~65% of children with SLOS; 13/26 children experienced failure-to-thrive (FTT), and 10/26 required gastrostomy. 7DHC concentrations, as a measure of severity, correlated with Total Feeding Score and the Oral Function subcategory score (p<.001), less so with Oral Structure, adverse behaviors or dysphagia. Correlations with cholesterol concentrations were not statistically significant. 7DHC > 0.24 mmol/L or Chol < 1.95 mmol/L is predictive of gastrostomy use. Feeding impairments may improve with age. Conclusions Feeding impairment is common and complex in patients with SLOS. Findings confirm that oral sensitivities, adverse feeding behaviors and risk of oral phase dysphagia are amenable to quantitative evaluation and analysis. Feeding difficulties in children with SLOS are correlated with plasma sterol concentrations, suggesting a link between the biochemical severity in SLOS and feeding function. These findings expand the behavioral phenotype of SLOS and begin to provide insights into the biologic causes of feeding difficulties. PMID:25039049

    Background Smith-Lemli-Opitz syndrome (SLOS) is a multiple malformation, neurodevelopmental disorder of cholesterol metabolism caused by mutations in 7-dehydrocholesterol reductase (DHCR7). Corpus callosum (CC) malformations and developmental delay are common manifestations of this disorder, but the relationship between the two has not been evaluated. We tested the hypothesis that shorter callosal length and smaller area correlates with higher serum 7-dehydrocholesterol (7DHC) and increased severity of neurodevelopmental delay in a large cohort of SLOS patients. Methods Thirty-six individuals with SLOS (18M/18F) between 0.20 and 12.5 years (mean = 3.9, SD = 3.6) and 36 typically developing controls (18M/18F) between 0.12 and 12.8 years (mean = 4.0, SD = 3.6) were each imaged one time on a 1.5T MR scanner. One mid-sagittal image per study was selected for manual measurement of CC cross-sectional area and length. Gross motor, fine motor, and language developmental quotients, anatomical severity score, and serum sterol levels were assessed with imaging measurements. Results Shorter CC length and smaller area correlated with lower developmental quotient in gross motor and language domains. Furthermore, length and area negatively correlated with a serum 7DHC, 8DHC, sterol ratio, and anatomical severity score, and positively correlated with total cholesterol. The degree of developmental delay ranged from mild to severe, involving all domains. Conclusions For individuals with SLOS, smaller callosal area and length are associated with higher serum 7DHC, anatomic severity, and motor and language delay. These findings suggest the relationship between callosal development, biochemistry, and neurodevelopment may lead to finding predictors of outcome in SLOS. PMID:23859856

    Smith-Lemli-Opitz syndrome (SLOS) is a neurodevelopmental disorder caused by inborn errors of cholesterol metabolism resulting from mutations in 7-dehydrocholesterol reductase (DHCR7). There are only a few studies describing the brain imaging findings in SLOS. This study examines the prevalence of magnetic resonance imaging (MRI) abnormalities in the largest cohort of patients with SLOS to date. Fifty-five individuals with SLOS (27M, 28F) between age 0.17 years and 25.4 years (mean = 6.2, SD = 5.8) received a total of 173 brain MRI scans (mean = 3.1 per subject) on a 1.5T GE scanner between September, 1998 and December, 2003, or on a 3T Philips scanner between October 2010 and September 2012; all exams were performed at the Clinical Center of the National Institutes of Health. We performed a retrospective review of these imaging studies for both major and minor brain anomalies. Aberrant MRI findings were observed in 53 of 55 (96%) SLOS patients, with abnormalities of the septum pellucidum the most frequent (42/55, 76%) finding. Abnormalities of the corpus callosum were found in 38 of 55 (69%) patients. Other findings included cerebral atrophy, cerebellar atrophy, colpocephaly, white matter lesions, arachnoid cysts, Dandy-Walker variant, and Type I Chiari malformation. Significant correlations were observed when comparing MRI findings with sterol levels and somatic malformations. Individuals with SLOS commonly have anomalies involving the midline and para-midline structures of the brain. Further studies are required to examine the relationship between structural brain abnormalities and neurodevelopmental disability in SLOS. PMID:23918729

    Background Normal post-squalene cholesterol biosynthesis is important for mammalian embryonic development. Neonatal mice lacking functional dehydrocholesterol ?7-reductase (Dhcr7), a model for the human disease of Smith-Lemli-Opitz syndrome, die within 24 hours of birth. Although they have a number of biochemical and structural abnormalities, one cause of death is from apparent respiratory failure due to developmental pulmonary abnormalities. Results In this study, we characterized further the role of cholesterol deficiency in lung development of these mice. Significant growth retardation, beginning at E14.5~E16.5, was observed in Dhcr7-/- embryos. Normal lobation but smaller lungs with a significant decrease in lung-to-body weight ratio was noted in Dhcr7-/- embryos, compared to controls. Lung branching morphogenesis was comparable between Dhcr7-/- and controls at early stages, but delayed saccular development was visible in all Dhcr7-/- embryos from E17.5 onwards. Impaired pre-alveolar development of varying severity, inhibited cell proliferation, delayed differentiation of type I alveolar epithelial cells (AECs) and delayed vascular development were all evident in knockout lungs. Differentiation of type II AECs was apparently normal as judged by surfactant protein (SP) mRNAs and SP-C immunostaining. A significant amount of cholesterol was detectable in knockout lungs, implicating some maternal transfer of cholesterol. No significant differences of the spatial-temporal localization of sonic hedgehog (Shh) or its downstream targets by immunohistochemistry were detected between knockout and wild-type lungs and Shh autoprocessing occurred normally in tissues from Dhcr7-/- embryos. Conclusion Our data indicated that cholesterol deficiency caused by Dhcr7 null was associated with a distinct lung saccular hypoplasia, characterized by failure to terminally differentiate alveolar sacs, a delayed differentiation of type I AECs and an immature vascular network at late gestational stages. The molecular mechanism of impaired lung development associated with sterol deficiency by Dhcr7 loss is still unknown, but these results do not support the involvement of dysregulated Shh-Patched-Gli pathway in causing this defect.

    The Smith-Lemli-Opitz syndrome (SLOS) is the first-described in a growing family of hereditary defects in cholesterol biosynthesis, and presents with a spectrum of serious abnormalities, including multiple dysmorphologies, failure to thrive, cognitive and behavioral impairments, and retinopathy. Using a pharmacologically induced rat model of SLOS that exhibits key hallmarks of the disease, including progressive retinal degeneration and dysfunction, we show that a high-cholesterol diet can substantially correct abnormalities in retinal sterol composition, with concomitant improvement of visual function, particularly within the cone pathway. Although histologic degeneration still occurred, a high-cholesterol diet reduced the number of pyknotic photoreceptor nuclei, relative to animals on a cholesterol-free diet. These findings demonstrate that cholesterol readily crosses the blood-retina barrier (unlike the blood-brain barrier) and suggest that cholesterol supplementation may be efficacious in treating SLOS-associated retinopathy.

    The RAH/Smith-Lemli-Opitz syndrome (RAH/SLOS) is an autosomal recessive malformation syndrome associated with increased levels of 7-dehydrocholesterol (7-DHC) and a defect of cholesterol biosynthesis at the level of 3{beta}-hydroxy-steroid-{Delta}{sup 7}-reductase (7-DHC reductase). Because rats exposed to inhibitors of 7-DHC reductase during development have a high frequency of holoprosencephaly (HPE), we have undertaken a search for biochemical evidence of RSH/SLOS and other possible defects of sterol metabolism among patients with various forms of HPE. We describe 4 patients, one with semilobar HPE and three others with less complete forms of the HPE sequence, in whom we have made a biochemical diagnosis of RAH/SLOS. The clinical and biochemical spectrum of these and other patients with RAH/SLOS suggests a role of abnormal sterol metabolism in the pathogenesis of their malformations. The association of HPE and RAH/SLOS is discussed in light of the recent discoveries that mutations in the embryonic patterning gene, Sonic Hedgehog (SHH), can cause HPE in humans and that the sonic hedgehog protein product undergoes autoproteolysis to form a cholesterol-modified active product. These clinical, biochemical, and molecular studies suggest that HPE and other malformations in SLOS may be caused by incomplete or abnormal modification of the sonic hedgehog protein and, possibly, other patterning proteins of the hedgehog class, a hypothesis testable in somatic cell systems. 37 refs., 1 fig.

    Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder of cholesterol biosynthesis caused by mutations in the DHCR7 gene. Thirty-seven ethnic Polish patients with SLOS underwent mutation analysis. The mutation frequencies in Polish patients were significantly different from those observed in Western European populations. Two mutations, W151X (22/68 alleles, 32%) and V326L (19/68 alleles, 28%), accounted for 60% of all observed in our cohort. Two missense mutations L68P and L360P have not been reported previously. In total, we report 15 DHCR7 mutations identified in Polish patients. By comparing clinical severity scores and the biochemical and molecular data, a genotype-phenotype correlation was attempted. In compound heterozygotes with one null mutation, the phenotype severity depends on the localization and type of the second mutation: mild phenotypes are correlated with mutations affecting the putative transmembrane domains TM1-TM6 or CT regions and severe phenotypes with mutations localized in TM7 and 4L region. The phenotypic differences of patients with the same genotype suggest that severity of the disease may be affected by other factors. PMID:15521979

    Cholesterol is an essential component of cellular membranes that is required for normal lipid organization and cell signaling. While the mechanisms associated with maintaining cholesterol homeostasis in the plasma and peripheral tissues have been well studied, the role and regulation of cholesterol biosynthesis in normal brain function and development have proven much more challenging to investigate. Smith-Lemli-Opitz syndrome (SLOS) is a disorder of cholesterol synthesis characterized by mutations of DHCR7 (7-dehydrocholesterol reductase) that impair the reduction of 7-dehydrocholesterol (7DHC) to cholesterol and lead to neurocognitive deficits, including cerebellar hypoplasia and austism behaviors. Here we have used a novel mass spectrometry-based imaging technique called cation-enhanced nanostructure-initiator mass spectrometry (NIMS) for the in situ detection of intact cholesterol molecules from biological tissues. We provide the first images of brain sterol localization in a mouse model for SLOS (Dhcr7?/?). In SLOS mice, there is a striking localization of both 7DHC and residual cholesterol in the abnormally developing cerebellum and brainstem. In contrast, the distribution of cholesterol in 1-day old healthy pups was diffuse throughout the cerebrum and comparable to that of adult mice. This study represents the first application of NIMS to localize perturbations in metabolism within pathological tissues and demonstrates that abnormal cholesterol biosynthesis may be particularly important for the development of these brain regions.

    Data from massively parallel sequencing or 'Next Generation Sequencing' of the human exome has reached a critical mass in both public and private databases, in that these collections now allow researchers to critically evaluate population genetics in a manner that was not feasible a decade ago. The ability to determine pathogenic allele frequencies by evaluation of the full coding sequences and not merely a single nucleotide polymorphism (SNP) or series of SNPs will lead to more accurate estimations of incidence. For demonstrative purposes, we analyzed the causative gene for the disorder Smith-Lemli-Opitz Syndrome (SLOS), the 7-dehydrocholesterol reductase (DHCR7) gene and determined both the carrier frequency for DHCR7 mutations, and predicted an expected incidence of the disorder. Estimations of the incidence of SLOS have ranged widely from 1:10,000 to 1:70,000 while the carrier frequency has been reported as high as 1 in 30. Using four exome data sets with a total of 17,836 chromosomes, we ascertained a carrier frequency of pathogenic DHRC7 mutations of 1.01%, and predict a SLOS disease incidence of 1/39,215 conceptions. This approach highlights yet another valuable aspect of the exome sequencing databases, to inform clinical and health policy decisions related to genetic counseling, prenatal testing and newborn screening.

    Smith-Lemli-Opitz syndrome (SLOS) is a recessive disease characterized by markedly elevated levels of 7-dehydrocholesterol (7-DHC) and reduced levels of cholesterol in tissues and fluids of affected individuals, due to defective 3?-hydroxysterol-?7-reductase (Dhcr7). Treatment of Sprague-Dawley rats with AY9944 (an inhibitor of Dhcr7) leads to similar biochemical features as observed in SLOS. Eighteen oxysterols previously have been identified as oxidation products of 7-DHC (most of them distinct from cholesterol (Chol)-derived oxysterols) in solution, in cells, and in brains obtained from Dhcr7-KO mice and AY9944-treated rats, formed either via free radical oxidation (peroxidation) or P450-catalyzed enzymatic oxidation. We report here the identification of five 7-DHC-derived oxysterols, including 3?,5?-dihydroxycholest-7-en-6-one (DHCEO), 4?- and 4?-hydroxy-7-DHC, 24-hydroxy-7-DHC and 7-ketocholesterol (7-kChol, an oxysterol that is normally derived from Chol), in the retinas of AY9944-treated rats by comparing the retention times and mass spectrometric characteristics with corresponding synthetic standards in HPLC-MS analysis. Levels of 4?- and 4?-hydroxy-7-DHC, DHCEO, and 7-kChol were quantified using d7-DHCEO as an internal standard. Among the five oxysterols identified, only 7-kChol was observed in retinas of control rats, but the levels of 7-kChol in retinas of AY9944-rats were >30-fold higher. Intravitreal injection of 7-kChol (0.25 mol) into a normal rat eye induced panretinal degeneration within one week; by comparison, contralateral (control) eyes injected with vehicle alone exhibited normal histology. These findings are discussed in the context of the potential involvement of 7-DHC-derived oxysterols in the retinal degeneration associated with the SLOS rat model and in SLOS patients.

    Smith-Lemli-Opitz syndrome (SLOS) is one of the most common recessive human disorders and is characterized by multiple congenital malformations as well as neurosensory and cognitive abnormalities. A rat model of SLOS has been developed that exhibits progressive retinal degeneration and visual dysfunction; however, the molecular events underlying the degeneration and dysfunction remain poorly understood. Here, we employed a well-controlled, ion-current-based approach to compare retinas from the SLOS rat model to retinas from age- and sex-matched control rats (n = 5/group). Retinas were subjected to detergent extraction and subsequent precipitation and on-pellet-digestion procedures and then were analyzed on a long, heated column (75 cm, with small particles) with a 7-h gradient. The high analytical reproducibility of the overall proteomics procedure enabled reliable expression profiling. In total, 1,259 unique protein groups, ?40% of which were membrane proteins, were quantified under highly stringent criteria, including a peptide false discovery rate of 0.4%, with high quality ion-current data (e.g. signal-to-noise ratio ? 10) obtained independently from at least two unique peptides for each protein. The ion-current-based strategy showed greater quantitative accuracy and reproducibility over a parallel spectral counting analysis. Statistically significant alterations of 101 proteins were observed; these proteins are implicated in a variety of biological processes, including lipid metabolism, oxidative stress, cell death, proteolysis, visual transduction, and vesicular/membrane transport, consistent with the features of the associated retinal degeneration in the SLOS model. Selected targets were further validated by Western blot analysis and correlative immunohistochemistry. Importantly, although photoreceptor cell death was validated by TUNEL analysis, Western blot and immunohistochemical analyses suggested a caspase-3-independent pathway. In total, these results provide compelling new evidence implicating molecular changes beyond the initial defect in cholesterol biosynthesis in this retinal degeneration model, and they might have broader implications with respect to the pathobiological mechanism underlying SLOS.

    A 3-month-old infant girl had manifestations of the Smith-Lemli-Opitz syndrome (SLOS) including typical positional anomalies of the limbs, apparent Hirschsprung disease, cataracts, ptosis, anteverted nares, cleft of the posterior palate, small tongue, broad maxillary alveolar ridges, and abnormally low serum cholesterol levels. Chromosomal analysis showed a de novo balanced translocation interpreted as 46,XX,t(7;20)(q32.1;q13.2). We hypothesize that the translocation breakpoint in this case interrupts one SLOS allele and that the other allele at the same locus has a more subtle mutation that was inherited from the other parent. This case, as well as cytogenetic observations in other SLOS cases, suggests that SLOS could be due to autosomal recessive mutation at a gene in 7q32. 33 refs., 3 figs., 1 tab.

    The Smith-Lemli-Opitz syndrome is a recessive inherited disorder characterized by neurologic developmental defects and dysmorphic features in many organs. Recently, abnormal cholesterol biosynthesis with impaired conversion of 7-dehydrocholesterol to cholesterol has been discovered in homozygotes. To reproduce the biochemical abnormality, BM 15.766, a competitive inhibitor of 7-dehydrocholesterol-delta 7-reductase, the enzyme that catalyzes the conversion of 7-dehydrocholesterol into cholesterol was fed by gavage to rats. After 14 d, plasma cholesterol concentrations declined from 48 mg/dl to 16 mg/dl and 7-dehydro-cholesterol levels rose from trace to 17 mg/dl. Hepatocytes surrounding the central vein developed balloon necrosis. Stimulating cholesterol synthesis with cholestyramine followed by BM 15.766 produced an additional 40% decline (P < 0.05) in plasma cholesterol and 34% increase in 7-dehydrocholesterol levels compared to the inhibitor alone. Adding 2% cholesterol to the diet during the second week of BM 15.766 treatment increased plasma cholesterol threefold and decreased 7-dehydrocholesterol concentrations 55%. Hepatic 3-hydroxy-3-methylglutaryl co-enzyme A (HMG-CoA) reductase activity increased 73% with a 3.9-fold rise in mRNA levels but cholesterol 7 alpha-hydroxylase activity decreased slightly though mRNA levels increased 1.4 times with BM 15.766 treatment. These results demonstrate that BM 15.766 is a potent inhibitor of 7-dehydrocholesterol-delta 7-reductase. The model reproduces abnormal cholesterol biosynthesis as seen in the Smith-Lemli-Opitz syndrome and is useful to test different treatment strategies. Stimulating early steps of cholesterol synthesis worsens the biochemical abnormalities while feeding cholesterol inhibits abnormal synthesis, improves the biochemical abnormalities and prevents liver damage.

    Smith-Lemli-Opitz/RSH syndrome (SLOS), a relatively common birth-defect mental-retardation syndrome, is caused by mutations in DHCR7, whose product catalyzes an obligate step in cholesterol biosynthesis, the conversion of 7-dehydrocholesterol to cholesterol. A null mutation in the murine Dhcr7 causes an identical biochemical defect to that seen in SLOS, including markedly reduced tissue cholesterol and total sterol levels, and 30- to 40-fold elevated concentrations of 7-dehydrocholesterol. Prenatal lethality was not noted, but newborn homozygotes breathed with difficulty, did not suckle, and died soon after birth with immature lungs, enlarged bladders, and, frequently, cleft palates. Despite reduced sterol concentrations in Dhcr7/ mice, mRNA levels for 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the rate-controlling enzyme for sterol biosynthesis, the LDL receptor, and SREBP-2 appeared neither elevated nor repressed. In contrast to mRNA, protein levels and activities of HMG-CoA reductase were markedly reduced. Consistent with this finding, 7-dehydrocholesterol accelerates proteolysis of HMG-CoA reductase while sparing other key proteins. These results demonstrate that in mice without Dhcr7 activity, accumulated 7-dehydrocholesterol suppresses sterol biosynthesis posttranslationally. This effect might exacerbate abnormal development in SLOS by increasing the fetal cholesterol deficiency. PMID:11560960

    Smith-Lemli-Opitz syndrome (SLOS) is an inborn error of cholesterol synthesis resulting from a defect in 7-dehydrocholesterol reductase (DHCR7), the enzyme that produces cholesterol from its immediate precursor 7-dehydrocholesterol. Current therapy employing dietary cholesterol is inadequate. As SLOS is caused by a defect in a single gene, restoring enzyme functionality through gene therapy may be a direct approach for treating this debilitating disorder. In the present study, we first packaged a human DHCR7 construct into adeno-associated virus (AAV) vectors having either type-2 (AAV2) or type-8 (AAV2/8) capsid, and administered treatment to juvenile mice. While a positive response (assessed by increases in serum and liver cholesterol) was seen in both groups, the improvement was greater in the AAV2/8-DHCR7 treated mice. Newborn mice were then treated with AAV2/8-DHCR7 and these mice, compared to mice treated as juveniles, showed higher DHCR7 mRNA expression in liver and a greater improvement in serum and liver cholesterol levels. Systemic treatment did not affect brain cholesterol in any of the experimental groups. Both juvenile and newborn treatments with AAV2/8-DHCR7 resulted in increased rates of weight gain indicating that gene transfer had a positive physiological effect. PMID:25024934

    Smith Lemli Opitz syndrome (SLOS) is an inherited malformation and mental retardation metabolic disorder with no cure. Mutations in the last enzyme of the cholesterol biosynthetic pathway, 7-dehydrocholesterol reductase (DHCR7), lead to cholesterol insufficiency and accumulation of its dehyrdocholesterol precursors, and contribute to its pathogenesis. The central nervous system (CNS) constitutes a major pathophysiological component of this disorder and remains unamenable to dietary cholesterol therapy due to the impenetrability of the blood brain barrier (BBB). The goal of this study was to restore sterol homeostasis in the CNS. To bypass the BBB, gene therapy using an adeno-associated virus (AAV-8) vector carrying a functional copy of the DHCR7 gene was administered by intrathecal (IT) injection directly into the cerebrospinal fluid of newborn mice. Two months post-treatment, vector DNA and DHCR7 expression was observed in the brain and a corresponding improvement of sterol levels seen in the brain and spinal cord. Interestingly, sterol levels in the peripheral nervous system also showed a similar improvement. This study shows that IT gene therapy can have a positive biochemical effect on sterol homeostasis in the central and peripheral nervous systems in a SLOS animal model. A single dose delivered three days after birth had a sustained effect into adulthood, eight weeks post-treatment. These observations pave the way for further studies to understand the effect of biochemical improvement of sterol levels on neuronal function, to provide a greater understanding of neuronal cholesterol homeostasis, and to develop potential therapies.

    Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder caused by reduced activity of 7-dehydrocholesterol (7DHC) reductase, resulting in a decreased level of cholesterol and increased concentrations of 7DHC and 8DHC in body fluids and tissues. Ten pregnancies at 25% risk of SLOS underwent prenatal testing. Diagnostic studies included DHCR7 mutation analysis in chorionic villus samples, amniotic fluid sterol analysis and serial measurements of oestriol (E3), pregnanetriol (PT), 7-dehydropregnanetriol (7DHPT) and 8-dehydroesteriol (8DHE3) concentrations in maternal urine samples obtained between 9 and 20 weeks of gestation. All tests were diagnostic and revealed nine unaffected foetuses (two normal homozygotes and seven DHCR7 heterozygotes) and one affected foetus. In the affected pregnancy, 7DHC and 8DHC in amniotic fluid were 9.87 and 3.7 microg/ml, respectively [reference range (RR) 0.0026 +/- 0.0015 microg/ml and not detectable, respectively] and maternal urinary steroid analyses showed increased ratios of 7DHPT/PT and 8DHE3/E3 of 0.74 and 1.7, respectively (RR 0-0.0147 and 0-0.019). In the heterozygous foetuses, 7DHPT/PT and 8DHE3/E3 ratios did not exceed those found in 48 normal controls. This is the first series of prenatal diagnostic testing for SLOS where non-invasive biochemical testing was performed in tandem with invasive diagnostic testing. We conclude that steroid measurements in maternal urine are a reliable means of prenatal diagnosis for SLOS. PMID:16451140

    Smith-Lemli-Opitz syndrome/RSH (SLOS) is a multiple congenital anomaly syndrome caused by mutations in the gene for Delta7-sterol reductase (DHCR7) which catalyses the last step in the biosynthesis of cholesterol. SLOS is among the common recessive disorders in Europeans but almost absent in most other populations. More than 40 mutations in the DHCR7 gene some of which are frequent have been described in SLOS patients of various origins. Here we report mutation analysis of the DHCR7 gene in SLOS patients from Poland (n = 15), Germany/Austria (n = 22) and Great Britain (n = 22). Altogether 35 different mutations were identified and the two null mutations IVS8-1G > C and W151X were the most frequent in the total sample. In all three populations three mutations accounted for >0.5 of SLOS chromosomes. The mutational spectra were, however, significantly different across these populations with each of the common mutations showing an east-west gradient (W151X, V326L) or vice versa (IVS8-1G > C). W151X is the most frequent (0.33) mutation in Polish SLOS patients. It has an intermediate frequency in German/Austrian patients (0.18) and is rare among British patients (0.02). V326L shows the same distribution pattern (Poland 0.23, Germany/Austria 0.18, Britain 0.02). In contrast IVS8-1G > C is most frequent in Britain (0.34) intermediate in Germany/Austria (0.20) and rare in Poland (0.03). All analysed IVS8-1G > C and V326L alleles shared the same DHCR7 haplotype, whereas the W151X mutation occurred on different haplotypes. There is evidence for both recurrent mutations and founder effects. Together this suggests that the common SLOS mutations in Europe have different geographic and historic origins and spread across the continent in opposite directions. PMID:11175299

    Patients with Smith-Lemli-Opitz syndrome have impaired ability to synthesize cholesterol due to attenuated activity of 7-dehydrosterol-delta(7)-reductase which catalyses the final step in cholesterol synthesis. Accumulation of 7- and 8-dehydrocholesterol is a result of the disorder and potentially these sterols could be used as precursors of a novel class of delta(7) and delta(8) unsaturated adrenal steroids and their metabolites. In this study, we have analyzed urine from SLOS patients in the anticipation of characterizing such metabolites. Gas chromatography/mass spectrometry (GC/MS) was used in the identification of two major metabolites as 7- and 8-dehydroversions of the well-known steroid pregnanetriol. Other steroids, such as 8-dehydro dehydroepiandrosterone (8-dehydro DHEA) and 7- or 8-dehydroandrostenediol were also identified, and several more steroids are present in urine but remain uncharacterized. As yet, the study provides no evidence for the production of ring-B unsaturated metabolites of complex steroids, such as cortisol. We believe that the following transformations can utilize ring-B dehydroprecursors: StAR transport of cholesterol, p450 side chain cleavage, 17-hydroxylase/17,20-lyase, 3beta-hydroxysteroid dehydrogenase, 3alpha-hydroxysteroid dehydrogenase, 17beta-hydroxysteroid dehydrogenase, 20alpha-hydroxysteroid dehydrogenase and 5beta-reductase. We have yet to prove the activity of adrenal 21-hydroxylase, 11beta-hydroxylase or 5alpha-reductase towards 7- or 8-dehydroprecursors. PMID:12477489

    We investigated the enzyme defect in late cholesterol biosynthesis in the Smith-Lemli-Opitz syndrome, a recessively inherited developmental disorder characterized by facial dysmorphism, mental retardation, and multiple organ congenital anomalies. Reduced plasma and tissue cholesterol with increased 7-dehydrocholesterol concentrations are biochemical features diagnostic of the inherited enzyme defect. Using isotope incorporation assays, we measured the transformation of the precursors, [3 alpha- 3H]lathosterol and [1,2-3H]7-dehydrocholesterol into cholesterol by liver microsomes from seven controls and four Smith-Lemli-Opitz homozygous subjects. The introduction of the double bond in lathosterol at C-5[6] to form 7-dehydrocholesterol that is catalyzed by lathosterol-5-dehydrogenase was equally rapid in controls and homozygotes liver microsomes (120 +/- 8 vs 100 +/- 7 pmol/mg protein per min, P = NS). In distinction, the reduction of the double bond at C-7 [8] in 7-dehydrocholesterol to yield cholesterol catalyzed by 7-dehydrocholesterol-delta 7-reductase was nine times greater in controls than homozygotes microsomes (365 +/- 23 vs 40 +/- 4 pmol/mg protein per min, P < 0.0001). These results demonstrate that the pathway of lathosterol to cholesterol in human liver includes 7-dehydrocholesterol as a key intermediate. In Smith-Lemli-Opitz homozygotes, the transformation of 7-dehydrocholesterol to cholesterol by hepatic microsomes was blocked although 7-dehydrocholesterol was produced abundantly from lathosterol. Thus, lathosterol 5-dehydrogenase is equally active which indicates that homozygotes liver microsomes are viable. Accordingly, microsomal 7-dehydrocholesterol-delta 7-reductase is inherited abnormally in Smith-Lemli-Opitz homozygotes. PMID:7560069

    Objective: We sought to examine the prevalence of EEG abnormalities in Smith-Lemli-Opitz syndrome (SLOS) as well as the relationship between interictal epileptiform discharges (IEDs) and within-subject variations in attentional symptom severity. Methods: In the context of a clinical trial for SLOS, we performed cross-sectional and repeated-measure observational studies of the relationship between EEG findings and cognitive/behavioral factors on 23 children (aged 4–17 years). EEGs were reviewed for clinical abnormalities, including IEDs, by readers blinded to participants' behavioral symptoms. Between-group differences in baseline characteristics of participants with and without IEDs were analyzed. Within-subject analyses examined the association between the presence of IEDs and changes in attention-deficit/hyperactivity disorder (ADHD) symptoms. Results: Of 85 EEGs, 43 (51%) were abnormal, predominantly because of IEDs. Only one subject had documented clinical seizures. IEDs clustered in 13 subjects (57%), whereas 9 subjects (39%) had EEGs consistently free of IEDs. While there were no significant group differences in sex, age, intellectual disability, language level, or baseline ADHD symptoms, autistic symptoms tended to be more prevalent in the “IED” group (according to Autism Diagnostic Observation Schedule–2 criteria). Within individuals, the presence of IEDs on a particular EEG predicted, on average, a 27% increase in ADHD symptom severity. Conclusions: Epileptiform discharges are common in SLOS, despite a relatively low prevalence of epilepsy. Fluctuations in the presence of epileptiform discharges within individual children with a developmental disability syndrome may be associated with fluctuations in ADHD symptomatology, even in the absence of clinical seizures.

    Pallister-Hall syndrome (PHS) was originally described in 1980 in six sporadic cases of children with structural anomalies including hypothalamic hamartoma, polydactyly, imperforate anus, and renal and pulmonary anomalies. In 1993, the first familial cases were reported, including affected sibs and vertical transmission. Three of these families are sufficiently large to allow initial evaluation by linkage studies to candidate genes or loci. We have evaluated candidate loci for PHS based on three clinical observations. The first is a patient with PHS-like malformations, including a hypothalamic hamartoma, and an unbalanced translocation involving 7q and 3p. The second is a family with familial PHS where the founder's father had an autosomal dominant hand malformation previously mapped to 17q. The third is the phenotypic overlap of PHS and Smith-Lemli-Opitz syndrome. In this report, we exclude these loci as candidates for linkage to the PHS phenotype on the basis of lod scores of less than-2.0. We conclude that hypothalamic hamartoma is not specific to PHS and that the dominant hand malformation in one of the families was a coincidence. To evaluate the relationship of PHS to Smith-Lemli-Opitz syndrome, we analysed levels of cholesterol and intermediate metabolites of the later stages of cholesterol biosynthesis. There is no evidence of a generalised disorder of cholesterol biosynthesis in patients with familial PHS. On genetic and biochemical grounds, we conclude that PHS and Smith-Lemli-Opitz syndrome are not allelic variants of a single locus. PMID:8950676

    Cholesterol homeostasis is critical for normal growth and development. In addition to being a major membrane lipid, cholesterol has multiple biological functions. These roles include being a precursor molecule for the synthesis of steroid hormones, neuroactive steroids, oxysterols, and bile acids. Cholesterol is also essential for the proper maturation and signaling of hedgehog proteins, and thus cholesterol is critical for embryonic development. After birth, most tissues can obtain cholesterol from either endogenous synthesis or exogenous dietary sources, but prior to birth, the human fetal tissues are dependent on endogenous synthesis. Due to the blood-brain barrier, brain tissue cannot utilize dietary or peripherally produced cholesterol. Generally, inborn errors of cholesterol synthesis lead to both a deficiency of cholesterol and increased levels of potentially bioactive or toxic precursor sterols. Over the past couple of decades, a number of human malformation syndromes have been shown to be due to inborn errors of cholesterol synthesis. Herein, we will review clinical and basic science aspects of Smith-Lemli-Opitz syndrome, desmosterolosis, lathosterolosis, HEM dysplasia, X-linked dominant chondrodysplasia punctata, Congenital Hemidysplasia with Ichthyosiform erythroderma and Limb Defects Syndrome, sterol-C-4 methyloxidase-like deficiency, and Antley-Bixler syndrome.

    Hirschsprung disease (HSCR) stands as a model for genetic dissection of complex diseases. In this model, a major gene, RET, is involved in most if not all cases of isolated (i.e., nonsyndromic) HSCR, in conjunction with other autosomal susceptibility loci under a multiplicative model. HSCR susceptibility alleles can harbor either heterozygous coding sequence mutations or, more frequently, a polymorphism within intron 1, leading to a hypomorphic RET allele. On the other hand, about 30% of HSCR are syndromic. Hitherto, the disease causing gene has been identified for eight Mendelian syndromes with HSCR: congenital central hypoventilation (CCHS), Mowat-Wilson (MWS), Bardet-Biedl (BBS), Shah-Waardenburg (WS4), cartilage-hair-hypoplasia (CHH), Smith-Lemli-Opitz (SLO), Goldberg-Sprintzsen (GSS), and hydrocephalus due to congenital stenosis of the aqueduct of sylvius (HSAS). According to the HSCR syndrome, the penetrance of HSCR trait varies from 5 to 70%. Trisomy 21 (T21) also predisposes to HSCR. We were able to collect a series of 393 patients affected by CCHS (n = 173), WS4 (n = 24), BBS (n = 51), MWS (n = 71), T21 (n = 46), and mental retardation (MR) with HSCR (n = 28). For each syndrome, we studied the RET locus in two subgroups of patients; i.e., with or without HSCR. We genotyped the RET locus in 393 patients among whom 195 had HSCR, and compared the distribution of alleles and genotypes within the two groups for each syndrome. RET acts as a modifier gene for the HSCR phenotype in patients with CCHS, BBS, and Down syndrome, but not in patients with MWS and WS4. The frequent, low penetrant, predisposing allele of the RET gene can be regarded as a risk factor for the HSCR phenotype in CCHS, BBS, and Down syndrome, while its role is not significant in MWS and WS4. These data highlight the pivotal role of the RET gene in both isolated and syndromic HSCR. PMID:17397038

    Formaldehyde is but one of many chemicals capable of causing the tight building syndrome or environmentally induced illness (EI). The spectrum of symptoms it may induce includes attacks of headache, flushing, laryngitis, dizziness, nausea, extreme weakness, arthralgia, unwarranted depression, dysphonia, exhaustion, inability to think clearly, arrhythmia or muscle spasms. The nonspecificity of such symptoms can baffle physicians from many specialties. Presented herein is a simple office method for demonstrating that formaldehyde is among the etiologic agents triggering these symptoms. The very symptoms that patients complain of can be provoked within minutes, and subsequently abolished, with an intradermal injection of the appropriate strength of formaldehyde. This injection aids in convincing the patient of the cause of the symptoms so he can initiate measure to bring his disease under control.

    Pathogenic variants in the DHCR7 gene cause Smith-Lemli-Opitz syndrome (SLOS), a defect of cholesterol biosynthesis resulting in an autosomal recessive congenital metabolic malformation disorder. In approximately 4% of patients, the second mutation remains unidentified. In this study, 12 SLOS patients diagnosed clinically and/or by elevated 7-dehydrocholesterol (7-DHC) have been investigated by customized multiplex ligation-dependent probe amplification (MLPA) analysis, because only one DHCR7 sequence variant has been detected. Two unrelated patients of this cohort carry different large deletions in the DHCR7 gene. One patient showed a deletion of exons 3-6. The second patient has a deletion of exons 1 and 2 (non-coding) and lacks the major part of the promoter. These two patients show typical clinical and biochemical phenotypes of SLOS. Second disease-causing mutations are p.(Arg352Trp) and p.(Thr93Met), respectively. Deletion breakpoints were characterized successfully in both cases. Such large deletions are rare in the DHCR7 gene but will resolve some of the patients in whom a second mutation has not been detected. PMID:25040602

    The abrupt exposure to urea foam formaldehyde insulation served as an alert to its spectrum of symptoms, including attacks of headache, flushing, laryngitis, dizziness, nausea, extreme weakness or exhaustion, arthralgia, an inability to concentrate, unwarranted depression, arrhythmia, or muscle spasms, and baffled physicians from many specialties. Later it was learned that toluene, xylene, benzene, natural gas, trichloroethylene, and many other chemicals were also capable of triggering chemical hypersensitivity. Other names for this condition include Environmentally Induced Illness (EI), the Tight Building Syndrome (TBS), the Sick Building Syndrome, and Building-Related Illness. The very symptoms patients complain of can be provoked within minutes and then subsequently alleviated with an intradermal injection of the appropriate strength of the triggering chemical. This technique aids in convincing the patient of the EI or TBS triggers so that the patient can begin to relate symptoms to environmental exposures and initiate measure to bring the disease under control. The key to safer buildings is increased ventilation, increased filtration of air, and decreased use of off-gassing synthetic materials.

    The spectrum of adipose tissue diseases ranges from obesity to lipodystrophy, and is accompanied by insulin resistance syndrome, which promotes the occurrence of type 2 diabetes, dyslipidemia and cardiovascular complications. Lipodystrophy refers to a group of rare diseases characterized by the generalized or partial absence of adipose tissue, and occurs with or without hypertrophy of adipose tissue in other sites. They are classified as being familial or acquired, and generalized or partial. The genetically determined partial forms usually occur as Dunnigan syndrome, which is a type of laminopathy that can also manifest as muscle, cardiac, neuropathic or progeroid involvement. Gene mutations encoding for PPAR-gamma, Akt2, CIDEC, perilipin and the ZMPSTE 24 enzyme are much more rare. The genetically determined generalized forms are also very rare and are linked to mutations of seipin AGPAT2, FBN1, which is accompanied by Marfan syndrome, or of BANF1, which is characterized by a progeroid syndrome without insulin resistance and with early bone complications. Glycosylation disorders are sometimes involved. Some genetically determined forms have recently been found to be due to autoinflammatory syndromes linked to a proteasome anomaly (PSMB8). They result in a lipodystrophy syndrome that occurs secondarily with fever, dermatosis and panniculitis. Then there are forms that are considered to be acquired. They may be iatrogenic (protease inhibitors in HIV patients, glucocorticosteroids, insulin, graft-versus-host disease, etc.), related to an immune system disease (sequelae of dermatopolymyositis, autoimmune polyendocrine syndromes, particularly associated with type 1 diabetes, Barraquer-Simons and Lawrence syndromes), which are promoted by anomalies of the complement system. Finally, lipomatosis is currently classified as a painful form (adiposis dolorosa or Dercum's disease) or benign symmetric multiple form, also known as Launois-Bensaude syndrome or Madelung's disease, which are sometimes related to mitochondrial DNA mutations, but are usually promoted by alcohol. In addition to the medical management of metabolic syndrome and the sometimes surgical treatment of lipodystrophy, recombinant leptin provides hope for genetically determined lipodystrophy syndromes, whereas modifications in antiretroviral treatment and tesamorelin, a GHRH analog, is effective in the metabolic syndrome of HIV patients. Other therapeutic options will undoubtedly be developed, dependent on pathophysiological advances, which today tend to classify genetically determined lipodystrophy as being related to laminopathy or to lipid droplet disorders.

    Tourette syndrome (TS) is a childhood-onset neurodevelopmental disorder characterized by multiple motor tics and at least one vocal or phonic tic, and often one or more comorbid psychiatric disorders. Premonitory sensory urges before tic execution and desire for "just-right" perception are central features. The pathophysiology involves cortico-striato-thalamo-cortical circuits and possibly dopaminergic system. TS is considered a genetic disorder but the genetics is complex and likely involves rare mutations, common variants, and environmental and epigenetic factors. Treatment is multimodal and includes education and reassurance, behavioral interventions, pharmacologic, and rarely, surgical interventions. PMID:26022170

    2014-01-01

    Dysregulation of cholesterol metabolism in the brain has been associated with many neurodegenerative disorders such as Alzheimers disease, Niemann-Pick type C disease, Smith-Lemli-Opitz syndrome, Hungtingtons disease and Parkinsons disease. Specifically, genes involved in cholesterol biosynthesis (24-dehydrocholesterol reductase, DHCR24) and cholesterol efflux (ATP-binding cassete transporter, ABCA1, and apolipoprotein E, APOE) have been associated with developing Alzheimers disease. Indeed, APOE was the first gene variation found to increase the risk of Alzheimers disease and remains the risk gene with the greatest known impact. Mutations in another cholesterol biosynthetic gene, 7-dehydrocholesterol reductase (DHCR7), cause Smith-Lemli-Opitz syndrome and impairment in cellular cholesterol trafficking caused by mutations in the NPC1 protein results in Niemann-Pick type C disease. Taken together, these findings provide strong evidence that cholesterol metabolism needs to be controlled at very tight levels in the brain. Recent studies have implicated microRNAs (miRNAs) as novel regulators of cholesterol metabolism in several tissues. These small non-coding RNAs regulate gene expression at the post-transcriptional level by either suppressing translation or inducing mRNA degradation. This review article focuses on how cholesterol homeostasis is regulated by miRNAs and their potential implication in several neurodegenerative disorders, such as Alzheimers disease. Finally, we also discuss how antagonizing miRNA expression could be a potential therapy for treating cholesterol related diseases. PMID:24907491

    This study aimed at developing through three clinical cases, the usefulness of topical apraclonidine 0.5% to confirm a diagnosis of Bernard-Horner syndrome. Pupil diameter measurements were performed in indoor, bright and dim light successively. Apraclonidine 0.5% was then applied topically to both eyes, and pupils were observed at 30 and 60 minutes. Apraclonidine demonstrated denervation hypersensitivity in all three cases. Anisocoria was reversed in two cases and corrected in the third case. Although the cocaine test should still be considered as the gold standard for BHS diagnosis, apraclonidine seems to be a useful drug to confirm clinically diagnosed Bernard-Horner syndrome PMID:19927485

    In order to study male gonadal function in Noonan syndrome, clinical and laboratory data, including inhibin B, were gathered in nine pubertal males diagnosed with Noonan syndrome. Bilateral testicular maldescent was observed in four, and unilateral cryptorchidism occurred in two. Puberty was delayed in three patients. Luteinising hormone (LH) levels were normal in all patients in our series, while follicle stimulating hormone (FSH) levels were raised in seven. Inhibin B was low in six males and just above the lower limit of normal in two. Importantly, all three men with normal testicular descent displayed signs of Sertoli cell dysfunction, indicating, in contrast to earlier reports, that bilateral cryptorchidism does not seem to be the main contributing factor to impairment of testicular function in Noonan syndrome. These findings suggest different mechanisms of disturbance in male gonadal function, which is frequently associated with Sertoli dysfunction. PMID:19189703

A 35-year-old man with hypertensive end-stage renal disease underwent kidney transplantation. Two months after surgery, the recipient was diagnosed with RHS and treated with antivirals and steroids. However, after using the antiviral agents for the recommended duration, facial paralysis occurred as a new presentation and he required further treatment. Otalgia and periauricular vesicles improved, but the facial palsy remained. PMID:26779429

    Reported here is a 22-year-old professional wrestler who was diagnosed to have Paget-Schroetter syndrome after Greco-Roman wrestling. On substantial neuromuscular examination and laboratory testing, he was found to have also thoracic outlet syndrome and heterozygous mutations for factor V Leiden and methyltetrahydrofolate reductase genes. To the best knowledge of the authors, the concomitance of these pathologies is discussed for the first time in the literature. PMID:19244272

    Profiling and imaging of cholesterol and its precursors by mass spectrometry (MS) are important in a number of cholesterol biosynthesis disorders, such as in Smith-Lemli-Opitz syndrome (SLOS), where 7-dehydrocholesterol (7-DHC) is accumulated in affected individuals. SLOS is caused by defects in the enzyme that reduces 7-DHC to cholesterol. However, analysis of sterols is challenging because these hydrophobic olefins are difficult to ionize for MS detection. We report here sputtered silver matrix-assisted laser desorption/ionization (MALDI)-ion mobility-MS (IM-MS) analysis of cholesterol and 7-DHC. In comparison with liquid-based AgNO3 and colloidal Ag nanoparticle (AgNP), sputtered silver NP (10-25 nm) provided the lowest limits-of-detection based on the silver coordinated [cholesterol + Ag]+ and [7-DHC + Ag]+ signals while minimizing dehydrogenation products ([M + Ag-2H]+). When analyzing human fibroblasts that were directly grown on poly-L-lysine-coated ITO glass plates with this technique, in situ, the 7-DHC/cholesterol ratios for both control and SLOS human fibroblasts are readily obtained. The m/z of 491 (specific for [7-DHC + 107Ag]+) and 495 (specific for [cholesterol + 109Ag]+) were subsequently imaged using MALDI-IM-MS. MS images were co-registered with optical images of the cells for metabolic ratio determination. From these comparisons, ratios of 7-DHC/cholesterol for SLOS human fibroblasts are distinctly higher than in control human fibroblasts. Thus, this strategy demonstrates the utility for diagnosing/assaying the severity of cholesterol biosynthesis disorders in vitro.

    Smith-Lemli-Opitz syndrome (SLOS) is an inherited metabolic disease in the cholesterol biosynthesis pathway which is characterised by accumulation of 7- and 8-dehydrocholesterol and by reduced cholesterol concentrations in all tissues and body fluids. With this study, we developed a new, rapid, robust and high-throughput tandem mass spectrometric method as routine application for the selective SLOS screening and therapy monitoring in serum and dried blood. After protein precipitation of 10 ?L serum or 4.7 mm dried blood spot, the sum of 7- and 8-dehydrocholesterol (DHC) was analysed by rapid chromatography combined with tandem mass spectrometry. Method comparison with GC-MS was performed for 46 serum samples. A comparison between serum and corresponding dried blood spots for DHC and cholesterol was performed with 40 samples from SLOS patients. Concentrations of DHC and cholesterol were analysed in 2 dried blood samples from newborns with SLOS and 100 unaffected newborns. Intra- and inter-assay variabilities ranged between 3.7 and 17.7% for serum and dried blood spots. Significant correlations between the new LC-MS/MS method and GC-MS were determined for DHC (r?=?0.937, p?diagnosed with SLOS from normal newborns in a retrospective analysis after 5 years. The developed method enables a rapid quantification of the sum parameter 7- and 8-DHC in newborns and SLOS patients under therapy in serum as well as dried blood spot samples. PMID:25963649

    Introduction?The CHARGE association (coloboma of the eyes; heart disease; atresia of the choanae; retarded growth and development; genital hypoplasia/genitourinary anomalies; ear anomalies and/or hearing loss) was first described in 1979 by Hall, and among its main features is hearing loss. This study presents a case aiming to establish relationships between performance on Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS) and Meaningful Use of Speech Scales (MUSS) tests and the analysis of hearing and language categories of a patient diagnosed with CHARGE syndrome, before and after cochlear implant (CI) surgery. Case Report?A 7-year-old girl was diagnosed with CHARGE. She had severe sensorineural hearing loss and was a prelingual unilateral CI user. We analyzed data from the patient's medical records regarding therapies and video recordings. Results?The patient showed positive results in all evaluations after CI. IT-MAIS rose from 5 to 90% following the use of CI. MUSS also rose, from 75 to 72.5%, after use of CI. Classification of Auditory Skills changed from category 1 before use of CI to category 6 after use of CI. Classification of Language Skills changed from category 1 before use of CI to category 3 after use of CI. The CI is an aid but there are many factors in the therapeutic process, and great heterogeneity in individuals diagnosed with CHARGE should be investigated. Conclusion?The development of listening and language skills after CI use was demonstrated by IT-MAIS and MUSS tests, and categorization of speech and hearing in this child with a diagnosis of CHARGE syndrome shows that CI can be an effective technological resource to provide information on hearing as one source for language construction.

    Premenstrual syndrome (PMS) and its derivative Premenstrual Dysphoric Disorder (PMDD) are controversial medical diagnoses. On one hand they are ubiquitous in English-language cultures; on the other they are for many emblematic of unnecessary medicalization of natural physiological processes. In this paper, we use data produced by IMS, a health care information and research firm, to analyze office-based medical practice related to PMS/PMDD in five countries. We come to several conclusions: 1. Relatively few doctors in any country diagnose women as suffering from PMS/PMDD, despite significant national variations in frequency of diagnosis; 2. Women diagnosed with this condition are usually prescribed a medication no matter what kind of specialist they see; and 3. In North America and the UK, practitioners generally follow USA practice guidelines which favour use of anti-depressive drugs like SSRIs but this is not the case in France and Germany which exhibit unique prescription patterns. In France hormonal treatment and analgesics dominate; in Germany the plant extract Vitex agnus-castus, considered an alternative therapy in much of the English-speaking world, is most common. We go on to discuss the relevance of these conclusions to discussions of variations in medical practices, to the existing PMS literature that claims high rates of prevalence for this condition, and to recent studies of "demedicalization" in certain domains.

    The aim of this study was to characterize the fetal phenotype of a cohort of individuals with confirmed diagnoses of Prader-Willi syndrome (PWS), a severe multi-system genetic disorder, diagnosed by a specific methylation test. We interviewed mothers of 106 individuals with PWS to obtain information about the pregnancy of their affected child. For 47 pregnancies of children younger than 10 years, we also reviewed the obstetric ultrasound and detailed obstetric history from medical records. We compared the PWS pregnancies with those of the sibling closest in age and with the general population. McNemars, Chi-square and Fisher exact tests were used for statistical analyses. Decreased fetal movements, small for gestational age (SGA), asymmetrical intrauterine growth (increased head/abdomen circumferences ratio) and polyhydramnios were found in 88%, 65%, 43%, and 34%, respectively (P?

    Cauda equina syndrome (CES) is a neurological syndrome presenting with non-specific symptoms and signs that often leads to diagnostic confusion and delay. Acute onset CES is a surgical emergency. The common aetiology is a prolapsed lumbar disc. If the diagnosis is missed, it can have devastating consequences for the patient and a high financial cost to healthcare providers. The objective of this study was to evaluate the efficacy of clinical assessment in clinching the diagnosis. Eighty patients who underwent urgent clinical assessment and magnetic resonance imaging (MRI) for suspected CES over a 1-year period (from January 1st 2008 to 31 December 2008) were included in the study. Fifteen of these patients had a CES and underwent urgent lumbar discectomy and decompression. Medical notes and MRI scans of all these patients were reviewed. The presenting symptoms and signs were analysed against a positive MRI scan. Chi-square test with Yates correction was used to test association of each clinical symptom and sign for a positive MRI. In this study, only 18.8% of assessed patients had a CES producing compression seen on the MRI. Presence of saddle sensory deficit was the only clinical feature with a statistically significant association with MRI positive CES (p = 0.03). This series shows that saddle sensory deficit has a higher predictive value than other clinical features in diagnosing a CES. However, as there is no symptom or sign which has an absolute predictive value in establishing the diagnosis of CES, any patient in whom a reasonable suspicion of CES arises must undergo urgent MRI to exclude this diagnosis.

    We report a male infant with midline defects, congenital heart disease and polydactyly, features suggestive of trisomy 13. However, the report of the karyotype was normal. By clinical findings the final diagnosis was likely to be Pseudotrisomy 13. Although the prognosis is poor in both conditions, the genetic study is always necessary to establish an adequate genetic counseling. Although there are syndromes with similar presentation as Meckel syndrome, Smith-Lemli-Opitz syndrome, Pallister-Hall syndrome and hydrolethalus, it is possible to make a diagnostic approach based on the perinatal history, birth weight, survival time, and some characteristics of each syndrome. However, limitations may exist to perform genetic studies in some countries, therefore the clinical criteria may be relevant. PMID:26294165

    Ankyloglossia or tongue-tie is a congenital anomaly affecting the tongue, which is characterized by thick, short lingual frenulum. This condition causes many difficulties such as limited tongue protrusion, breastfeeding difficulties, speech impairment and lack of self-confidence. It is very rarely associated with any other congenital craniofacial disorders such as cleft lip, X-linked cleft palate, Van der Woude syndrome, Smith-Lemli-Opitz syndrome, Orofacial digital syndrome, Beckwith Weidman syndrome or Simpson-Golabi-Behmel syndrome. This article presents a rare case of ankyloglossia associated with cleft lip treated with diode laser in a 12-year-old Indian boy who had undergone surgical correction of associated cleft lip soon after birth. Correction of ankyloglossia at a young age would lead to enhanced phonetics, improved oral hygiene, and overall personality development. PMID:26941523

    Klippel Trenaunay Weber syndrome (KTWS) is a rare disease characterized by hemihypertrophy, variceal enlargement of the veins, and arteriovenous (AV) malformations. Renal involvement in KTWS is not known except in rare case reports. Herein, we present a case of KTWS with nephrotic syndrome. A 52-year-old male was admitted due to dyspnea and swelling of the body for the last three months. The pathological physical findings were diffuse edema, decreased lung sounds at the right basal site, increased diameter and decreased length of the left leg compared with the right one, diffuse variceal enlargements, and a few hemangiomatous lesions on the left leg. The pathological laboratory findings were hypoalbuminemia, hyperlipidemia, increased creatinine level (1.23 mg/dL), and proteinuria (7.6 g/day). Radiographic pathological findings were cystic lesions in the liver, spleen, and kidneys, splenomegaly, AV malformation on the left posterolateral thigh, and hypertrophy of the soft tissues of the proximal left leg. He was diagnosed to have KTWS with these findings. Renal biopsy was performed to determine the cause of nephrotic syndrome. The pathologic examination was consistent with focal segmental sclerosis (FSGS). He was started on oral methylprednisolone at the dosage of 1 mg/kg and began to be followedup in the nephrology outpatient clinic. PMID:26000182

The main anomalies are summarized in the acronym LEOPARD in which each letter corresponds to mnemonic for the major features of this disorder:multiple Lentigines, ECG conduction abnormalities, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth, and sensory neural Deafness. A Four year old male patient reported with the chief complaint of decayed anterior tooth without any relevant past medical history. Based on the clinical features; the child was subjected to genetic and general physical appraisal which helped in identifying Leopard syndrome. A multidisciplinary approach by the pedodontist and medical consultants aided in the identification and management of this rare syndrome. LEOPARD syndrome has been rarely reported in the diseases associated with oro-dental or craniofacial anomalies. In this case report we describe these anomalies and discuss the relationship between them and the proposed etiology of the disease. PMID:25572376

    Well-established cell culture models were combined with new analytical methods to assess the effects of small molecules on the cholesterol biosynthesis pathway. The analytical protocol, which is based on sterol derivation with the dienolphile PTAD, was found to be reliable for the analysis of 7-DHC and desmosterol. The PTAD method was applied to the screening of a small library of pharmacologically active substances, and the effect of compounds on the cholesterol pathway was determined. Of some 727 compounds, over 30 compounds decreased 7-DHC in Dhcr7-deficient Neuro2a cells. The examination of chemical structures of active molecules in the screen grouped the compounds into distinct categories. In addition to statins, our screen found that SERMs, antifungals, and several antipsychotic medications reduced levels of 7-DHC. The activities of selected compounds were verified in human fibroblasts derived from Smith-Lemli-Opitz syndrome (SLOS) patients and linked to specific transformations in the cholesterol biosynthesis pathway.

    Summary Lipid rafts are specialized membrane microdomains that serve as organizing centers for assembly of signaling molecules, influence membrane fluidity and trafficking of membrane proteins, and regulate different cellular processes such as neurotransmission and receptor trafficking. In this article, we provide an overview of current methods for studying lipid rafts and models for how lipid rafts might form and function. Next, we propose a potential mechanism for regulating lipid rafts in the brain via local control of cholesterol biosynthesis by neurotrophins and their receptors. Finally, we discuss evidence that altered cholesterol metabolism and/or lipid rafts play a critical role in the pathophysiology of multiple CNS disorders, including Smith-Lemli-Opitz syndrome, Huntington, Alzheimer's, and Niemman-Pick Type C diseases.

    Smith-Lemli-Opitz syndrome, a congenital and developmental malformation disease, is typified by abnormal accumulation of 7-dehydrocholesterol (7DHC), the immediate precursor of cholesterol (CHOL), and depletion thereof. Knowledge of the effect of 7DHC on the biological membrane is, however, still fragmentary. In this study, large-scale atomistic molecular dynamics simulations, employing two distinct force fields, have been conducted to elucidate differences in the structural properties of a hydrated dimyristoylphosphatidylcholine bilayer due to CHOL and 7DHC. The present series of results indicate that CHOL and 7DHC possess virtually the same ability to condense and order membranes. Furthermore, the condensing and ordering effects are shown to be strengthened at increasing sterol concentrations.

    Borderline personality disorder is a personality dysfunction that is characterized by disinhibition and impulsivity, which oftentimes manifest as self-regulation difficulties. Patients with this disorder have always been present in medical settings, but have been described as difficult patients rather than patients with borderline personality disorder. According to empirical findings, a number of behaviors and medical syndromes/diagnoses are suggestive of borderline personality disorder. Suggestive behaviors in the medical setting may include aggressive or disruptive behaviors, the intentional sabotage of medical care, and excessive healthcare utilization. Suggestive medical syndromes and diagnoses in the medical setting may include alcohol and substance misuse (including the abuse of prescription medications), multiple somatic complaints, chronic pain, obesity, sexual impulsivity, and hair pulling. While not all-inclusive or diagnostic, these behaviors and syndromes/diagnoses may invite further clinical evaluation of the patient for borderline personality disorder. PMID:26351624

The recently revised International Headache Society (IHS) criteria, The International Classification of Headache Disorders, is a step in the right direction to improving our diagnostic accuracy. These criteria are the basis for scientific studies and serve as the foundation for future research and clinical care. In this article, the diagnostic issues related to migraine and childhood periodic syndromes in the IHS 2004 revisions are reviewed. PMID:16157064

    The accuracy of diagnosing hypothyroidism in 160 adults with Down syndrome was examined. A significant association between a clinical diagnosis of hypothyroidism and increasing age was found but no significant association was found between a clinical and a biochemical diagnosis. Regular biochemical screening is recommended. (Author/SW)

    Purpose: To investigate the association between metabolic syndrome and prostate cancer risk in Turkish men. Methods: We examined data from 220 patients with prostate cancer and 234 men in a control group with benign biopsy results, who had a serum prostate-specific antigen (PSA) level ⩾ 4 ng/ml, or an abnormal digital rectal examination finding and who underwent transrectal ultrasound-guided prostate biopsy at two main training and research hospitals between February 2009 and April 2013. Metabolic syndrome was diagnosed according to The Society of Endocrinology and Metabolism of Turkey metabolic-syndrome criteria. Age, total PSA, waist circumference, body mass index, lipid profiles, fasting blood sugar level, blood pressure level and metabolic syndrome were considered for analysis. Results: A total of 454 patients were enrolled: 85 cases in group 1 (38.6% of 220 prostate cancer cases) and 104 control subjects in group 2 (40.4% of 234 controls) were diagnosed with metabolic syndrome. Higher ages and lower high-density lipoprotein-cholesterol were two parameters that were significant only in the prostate cancer group with metabolic syndrome. There was no significant predictor factor for prostate cancer alone; however, higher triglycerides (odds ratio [OR], 1.286; 95% confidence interval [CI] 1.09–1.82 and 1.142; 95% CI 1.06–1.62) and fasting glucose levels (OR, 1.222; 95% CI 1.08–1.61 and 1.024; 95% CI 1.07–1.82) were significant predictors in both the prostate cancer group and control group. Conclusions: We found little evidence to support the hypothesis that increased incidence of metabolic syndrome (or its components) contributes to increased incidence of prostate cancer. A larger, prospective, multicentre investigation is mandatory to confirm if there is any relationship between metabolic syndrome and prostate cancer. PMID:25755679

    Fuchs' syndrome (Stevens-Johnson syndrome without skin involvement) is a sporadically diagnosed disease. Most authors consider it to be a pure mucosal variant of Stevens-Johnson syndrome; however, some consider the syndrome a separate entity. The complete absence of cutaneous symptoms may be the reason that not all cases of Fuchs' syndrome are diagnosed and properly classified. The authors describe a case of a 22-year-old patient suffering only from mucosal symptoms, diagnosed as Fuchs' syndrome from the context of the tests performed. A Mycoplasma pneumoniae infection triggered the disease onset. Mycoplasma infection, as a trigger factor of Fuchs' syndrome in adults, has so far been described in only a few isolated cases worldwide. PMID:25580788

    The prevalence of type 2 diabetes continuously increases globally. The traditional Chinese medicine (TCM) can stratify the diabetic patients based on their different TCM syndromes and, thus, allow a personalized treatment. Metabolomics is able to provide metabolite biomarkers for disease subtypes. In this study, we applied a metabolomics approach using an ultraperformance liquid chromatography (UPLC) coupled with quadruple-time-of-flight (QTOF) mass spectrometry system to characterize the metabolic alterations of different TCM syndromes including excess and deficiency in patients diagnosed with diabetes mellitus (DM). We obtained a snapshot of the distinct metabolic changes of DM patients with different TCM syndromes. DM patients with excess syndrome have higher serum 2-indolecarboxylic acid, hypotaurine, pipecolic acid, and progesterone in comparison to those patients with deficiency syndrome. The excess patients have more oxidative stress as demonstrated by unique metabolite signatures than the deficiency subjects. The results provide an improved understanding of the systemic alteration of metabolites in different syndromes of DM. The identified serum metabolites may be of clinical relevance for subtyping of diabetic patients, leading to a personalized DM treatment. PMID:25667595

    Segmental progeroid syndromes are rare, heterogeneous disorders characterized by signs of premature aging affecting more than one tissue or organ. A prototypic example is the Werner syndrome (WS), caused by biallelic germline mutations in the Werner helicase gene (WRN). While heterozygous lamin A/C (LMNA) mutations are found in a few nonclassical cases of WS, another 10%–15% of patients initially diagnosed with WS do not have mutations in WRN or LMNA. Germline POLD1 mutations were recently reported in five patients with another segmental progeroid disorder: mandibular hypoplasia, deafness, progeroid features syndrome. Here, we describe eight additional patients with heterozygous POLD1 mutations, thereby substantially expanding the characterization of this new example of segmental progeroid disorders. First, we identified POLD1 mutations in patients initially diagnosed with WS. Second, we describe POLD1 mutation carriers without clinically relevant hearing impairment or mandibular underdevelopment, both previously thought to represent obligate diagnostic features. These patients also exhibit a lower incidence of metabolic abnormalities and joint contractures. Third, we document postnatal short stature and premature greying/loss of hair in POLD1 mutation carriers. We conclude that POLD1 germline mutations can result in a variably expressed and probably underdiagnosed segmental progeroid syndrome. PMID:26172944

    Hypothalamic-pituitary-adrenal axis impairment in anorexia nervosa is marked by hypercortisolemia, and psychiatric disorders occur in the majority of patients with Cushing’s syndrome. Here we report a patient diagnosed with anorexia nervosa who also developed Cushing’s syndrome. A 26-year-old female had been treated for anorexia nervosa since she was 17 years old, and also developed depression and paranoid schizophrenia. She was admitted to the Department of Endocrinology, Metabolism, and Internal Medicine with a preliminary diagnosis of Cushing’s syndrome. Computed tomography revealed a 27 mm left adrenal tumor, and she underwent laparoscopic adrenalectomy. She was admitted to hospital 6 months after this procedure, at which time she did not report any eating or mood disorder. This is a rare case report of a patient with anorexia nervosa in whom Cushing’s syndrome was subsequently diagnosed. Diagnostic difficulties were caused by the signs and symptoms presenting in the course of both disorders, ie, hypercortisolemia, osteoporosis, secondary amenorrhea, striae, hypokalemia, muscle weakness, and depression.

    Gardner Diamond syndrome is a rare condition characterized with painful ecchymoses in different parts of the body and cutaneous and mucosal hemorrhages. The etiology is not known fully and psychogenic factors are thought to be involved. Cutaneous lesions and hemorrhages develop mostly following emotional stress and rarely minor traumas and may recur. Although the extremities are involved with the highest rate, the lesions may be observed in any part of the body. Hemostatic tests are generally normal. The majority of the subjects is composed of young women. It is observed more rarely in men and children. In this article, a patient who presented with recurring painful echymoses and bleeding disorder and diagnosed with Gardner Diamond syndrome by intracutaneous injection of autologous blood was presented to emphasize that this syndrome is observed rarely in the childhood and should be considered not only in the differential diagnosis of cutaneous lesions, but also in the differential diagnosis of various system hemorrhages.

    Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are caused by loss of function of imprinted genes in the 15q11-13 critical region. Reports of PWS and AS in close relatives within the same family are rare. We report on the diagnosis of a familial unbalanced 10;15 translocation causing AS in a child that led to the prenatal diagnosis of an unbalanced 10;15 translocation with resultant deletion of the Prader-Willi critical region in her maternal uncle's offspring.

    Aim: The aim of this study was to determine the long-term results of children followed up with a diagnosis of nephrotic syndrome in a single center. Materials and Method: The medical data of 33 patients aged between 6 months and 10 years who were diagnosed with idiopathic nephrotic syndrome in our center between January 2000 and December 2012 and followed up for a period of 2–12 years were reviewed (Gulhane Military Medical Academy Ethics committee, 07.11.2012/10). Results: The mean age of disease onset was 3.2±2.04 years (range: 0.5–10 years) and the mean follow-up period was 6±3.4 years (range: 2–12 years). Thirteen (39.4%) of the study group (or the patients) were female and 20 (60.6%) were male. Twenty seven (1.8%) of the patients were sensitive to steroid and 6 (18.1%) were resistant to steroid. Four (12.1%) of the steroid-resistant patients had steroid-dependent nephrotic syndrome, 5 (15.2%) had frequently relapsing nephrotic syndrome and 18 (54.5%) had rarely relapsing nephrotic syndrome. Histopathological diagnoses of six patients who underwent biopsy because of resistance to steroid were as follows: focal segmental glomerulosclerosis (n=3), C1q nephropathy (n=1), diffuse mesangial proliferation (n=1) and membraneous nephropathy (n=1). Fifteen (45.5%) patients entered into full remission and 2 (6%) patients developed chronic renal failure. Treatment complications including decreased bone mineral density in three patients (9%), short stature in 2 patients (6%) and cataract in 2 patients (6%) developed. Conclusions: Children with nephrotic syndrome carry a risk in terms of short stature, osteoporosis, cataract and renal failure in the long-term follow-up. It was observed that our rates of response to steroid were similar to the literature and the most common histopathological diagnosis was focal segmental glomerulosclerosis in our patients who underwent biopsy because of resistance to steroid. It was thought that multi-center studies should be conducted to demonstrate regional or national differences related with long-term results of childhood nephrotic syndrome. PMID:26078695

    In utero isolated ductal closure is uncommon and can lead to congestive heart failure, fetal hydrops and death if not recognized. A case report of premature spontaneus ductal closure in the third trimester of pregnancy in a fetus postnatally diagnosed as Adams-Olivier Syndrome is presented. On ultrasound examination an intrauterine growth restriction, defects of bones of hands and feet as well as ventriculomegaly were found. No nonsteroid drug treatment during pregnancy was applied. Fetal echocardiography was performed following an abnormal four-chamber view. Premature ductal closure was diagnosed. Fetal echocardiogram showed absent flow in the ductus arteriosus, dilated right ventricle with decreased function, and moderate tricuspid and pulmonary valve insufficiency with no signs of fetal hydrops. An elective cesarean section was performed. All abnormalities observed on former echocardiogram exam withdrew within 3 months of infant's life. The infant stays in the tertiary care centre due to the extracardiac malformations. PMID:17076195

    Collecting phenotypic data necessary for genetic analyses of neuropsychiatric disorders is time consuming and costly. Development of web-based phenotype assessments would greatly improve the efficiency and cost-effectiveness of genetic research. However, evaluating the reliability of this approach compared to standard, in-depth clinical interviews is essential. The current study replicates and extends a preliminary report on the utility of a web-based screen for Tourette Syndrome (TS) and common comorbid diagnoses (obsessive compulsive disorder (OCD) and attention deficit/hyperactivity disorder (ADHD)). A subset of individuals who completed a web-based phenotyping assessment for a TS genetic study was invited to participate in semi-structured diagnostic clinical interviews. The data from these interviews were used to determine participants' diagnostic status for TS, OCD, and ADHD using best estimate procedures, which then served as the gold standard to compare diagnoses assigned using web-based screen data. The results show high rates of agreement for TS. Kappas for OCD and ADHD diagnoses were also high and together demonstrate the utility of this self-report data in comparison previous diagnoses from clinicians and dimensional assessment methods.

    A 72-year-old woman was diagnosed with 5q- myelodysplastic syndrome in the course of an indolent multiple myeloma (MM). Bone marrow (BM) cytogenetics disclosed two unrelated clones: 46,XX,del(5)(q13q33), and [47,X,-X,der(1;21)(q10;q10),-4,-4,+5,del(5)(q13q31),+7,der(7)t(1;7)(p34.2;p22),add(8)(p23),-13,+15,der(16) t(1;16)(q23;q12.2),+19,-21,+mar1,+mar2]. The last complex karyotype belonged to malignant plasma cells. FISH and SKY techniques demonstrated different 5q deletions. EGR1 gene (on 5q31) lost in 5q- syndrome remained in 5q- plasma cells. Biclonal evolution was noted: myeloid 5q- cells added a deletion 13q and plasma cells showed monosomy 13. Patient achieved complete cytogenetic response of 5q- syndrome with low-dose of lenalidomide, and a partial remission of MM with high-dose of lenalidomide/dexamethasone combination. PMID:23891188

    Background Cyclic vomiting syndrome (CVS) in adults is a disorder characterized by recurrent and stereotypic episodes of severe nausea, vomiting and abdominal pain separated by symptom-free intervals. Our goal was to investigate gastric emptying (GE) in CVS patients. Material/Methods This was a retrospective study of 30 adult patients who met Rome III diagnostic criteria for CVS. Rapid GE was defined using two different predefined criteria as either <50% isotope retention or <65% isotope retention at 1st hour and/or <20% at 2nd hour. Results Of the 30 patients (25 had 4-hr GE) diagnosed with CVS, 22 were females and 8 males with a mean age of 39 years. Overall, 20 (80%) of the 25 CVS patients met the predefined criteria of <50% retention for rapid GE in the first hour. Fifteen (60%) met the 2-hour criteria for rapid emptying of <20% retention. Five (16.6%) patients of the 25 had a normal GE with a mean retention at the first hour of 65% (5278%). Nine (36%) also met another predefined criteria of <35% retention for rapid GE in the first hour. Sixteen (64%) met criteria for normal GE. Conclusions (1) In adult CVS patients, GE is either rapid or normal, clearly distinguishing this entity from gastroparesis. (2) Cyclic vomiting syndrome is an important new etiology to explain the finding of rapid GE on a radionuclide test. (3) We suggest that rapid gastric emptying should be added as supportive criteria for diagnosing CVS in adults. PMID:25145650

    Objective: To compare the plaque composition between stable and unstable plaques, characterize unstable plaque by using iMap-intravascular ultrasound (IVUS), and quantify the diagnostic criteria for unstable plaque. Methods: Thirty-three acute coronary syndrome (ACS) patients who had undergone coronary angiography and IVUS from February 19, 2014 to December 19, 2014 at Peking University People’s Hospital were enrolled in the study. Baseline data were collected. The patients were divided into two groups according to their gray-scale IVUS imaging, stable plaque and unstable plaque. A difference-in-difference evaluation was performed using the baseline data and off-line iMap imaging results between the two groups. A receiver operating characteristic (ROC) curve was constructed to obtain the optimal cut-off value to diagnose unstable plaque. Results: Percentages of fibrotic and necrotic tissues, absolute values of lipidic, necrotic, and calcified tissues, and plaque burden were independent predictors for unstable plaque. Absolute necrotic area was the best predictor and exhibited the highest diagnostic value for plaque vulnerability (area under the curve (AUC)=0.806, P=0.000, 95% CI (0.718, 0.894)). The cut-off score for predicting unstable plaque was 4.0 mm2. Conclusions: This study attempted to propose a cut-off value based on absolute necrotic area using iMap-IVUS to predict plaque vulnerability in patients with ACS. This score might provide a valuable reference for diagnosing unstable plaque. PMID:26537210

    Comorbid conditions have rarely been systematically studied among patients with myelodysplastic syndromes (MDS). We conducted a large population-based study to assess the role of comorbidity in the survival of newly diagnosed MDS patients. This study included 1,708 MDS patients (age ? 66 years) diagnosed in the US during 20012002, with follow-up through the end of 2004. Hazard ratios (HRs) were estimated using multivariate Cox proportional hazard models. The median survival time was approximately 18 months. Fifty one percent of MDS patients had comorbid conditions. Patients with comorbid conditions had significantly greater risk of death than those without comorbidities. The HR was 1.19 (95% confidence interval [CI]: 1.051.36) and 1.77 (95% CI: 1.502.08) for those with a Charlson index of 12 and ? 3, respectively. The risk of death increases with Charlson index. MDS patients who have congestive heart failure or chronic obstructive pulmonary disease had significantly shorter survival than patients without those conditions, whereas diabetes did not appear to have an impact on survival. This study confirms comorbidity as a significant and independent determinant of MDS survival, and the findings underscore the importance to take comorbid conditions into account when assessing the prognosis of MDS.

    Traumatic brain injuries and other blast-related injuries have been identified as the signature injury of the wars in Iraq and Afghanistan. Some operational units in Iraq, especially those responsible for clearing roadways, were exposed to hundreds of blast incidents and thousands of individual doses of concussive energy during their lengthy deployments. Using operational records maintained by a single command element, the researchers conducted a retrospective cohort study evaluating the association between estimated individual exposures to blasts and the risk for postconcussion syndrome (PCS) and posttraumatic stress disorder (PTSD). Tactical records documented all of the relevant details of the subjects' exposures to blasts during their missions. During the study period there were 313 blasts involving 418 service members resulting in 4,250 blast person events. Of that population, 12.9% were diagnosed with PCS, 8.6% with PTSD, and 5.3% with both. This study suggests that estimating the total individual dosage to concussive forces through physical evidence at the scene could be a useful predictor of future brain-disorder diagnoses. Those in vehicles sustaining heavy blast damage are at increased risk of being diagnosed with PTSD with a rate ratio of 2.79 (95% CI, 1.27-6.13) and PTSD in conjunction with PCS with a rate ratio of 4.10 (95% CI, 1.63-10.28). Standardization of the data collection method for blast incidents and additional follow-up studies could lead to the development of better ways of monitoring operational risk factors for negative health outcomes, plans to intervene in order to minimize health risks, and establish customized follow-up protocols based on specific dosage thresholds.

    Preconjugal ciliates learn classical repetition error-correction codes to safeguard mating messages and replies from corruption by "rivals" and local ambient noise. Because individual cells behave as memory channels with Szilrd engine attributes, these coding schemes also might be used to limit, diagnose, and correct mating-signal errors due to noisy intracellular information processing. The present study, therefore, assessed whether heterotrich ciliates effect fault-tolerant signal planning and execution by modifying engine performance, and consequently entropy content of codes, during mock cell-cell communication. Socially meaningful serial vibrations emitted from an ambiguous artificial source initiated ciliate behavioral signaling performances known to advertise mating fitness with varying courtship strategies. Microbes, employing calcium-dependent Hebbian-like decision making, learned to diagnose then correct error syndromes by recursively matching Boltzmann entropies between signal planning and execution stages via "power" or "refrigeration" cycles. All eight serial contraction and reversal strategies incurred errors in entropy magnitude by the execution stage of processing. Absolute errors, however, subtended expected threshold values for single bit-flip errors in three-bit replies, indicating coding schemes protected information content throughout signal production. Ciliate preparedness for vibrations selectively and significantly affected the magnitude and valence of Szilrd engine performance during modal and non-modal strategy corrective cycles. But entropy fidelity for all replies mainly improved across learning trials as refinements in engine efficiency. Fidelity neared maximum levels for only modal signals coded in resilient three-bit repetition error-correction sequences. Together, these findings demonstrate microbes can elevate survival/reproductive success by learning to implement classical fault-tolerant information processing in social contexts. PMID:23966987

    Background Lynch syndrome (LS) is a hereditary condition that increases the risk for endometrial and other cancers. The identification of endometrial cancer (EC) patients with LS has the potential to influence life-saving interventions. We aimed to study the prevalence of LS among EC patients in our population. Methods Universal screening for LS was applied for a consecutive series EC. Tumor testing using microsatellite instability (MSI), immunohistochemistry (IHC) for mismatch-repair (MMR) protein expression and MLH1-methylation analysis, when required, was used to select LS-suspicious cases. Sequencing of corresponding MMR genes was performed. Results One hundred and seventy-three EC (average age, 63 years) were screened. Sixty-one patients (35%) had abnormal IHC or MSI results. After MLH1 methylation analysis, 27 cases were considered suspicious of LS. From these, 22 were contacted and referred for genetic counseling. Nineteen pursued genetic testing and eight were diagnosed of LS. Mutations were more frequent in younger patients (<50 yrs). Three cases had either intact IHC or MSS and reinforce the need of implement the EC screening with both techniques. Conclusion The prevalence of LS among EC patients was 4.6% (8/173); with a predictive frequency of 6.6% in the Spanish population. Universal screening of EC for LS is recommended. PMID:24244552

    This study aimed to evaluate the diagnostic value of high-frequency ultrasound examination for carpal tunnel syndrome (CTS). A total of 63 wrists from 45 patients diagnosed with CTS were selected as the study group, and 43 asymptomatic wrists of 40 cases were included as the normal control group. Parameters such as the transverse diameter, vertical diameter, cross-sectional area (CSA), and flattening rate (FR) of the carpal tunnel radioulnar joint, postular bone, and median nerve in the hamate bone hook plane were measured, and the differences between the two groups were compared. The median nerve CSA in the postular bone plate was significantly greater in the study group than in the normal control group (0.170.05 vs. 0.090.02, P<0.01), and the FR at the hook of the hamate was significantly higher in the study group (3.520.86 vs. 3.210.26, P<0.01). Our results suggest that ultrasonography can effectively provide dynamic real-time images of the wrist in addition to being painless, non-invasive, and associated with relatively low costs. Based on our findings, we believe that ultrasonography is an effective examination method for CTS. When the threshold of the median nerve CSA in the postular bone plate was set as 10 mm2, the diagnostic sensitivity and specificity were 92% and 86%, respectively. Therefore, the median nerve CSA may represent a good clinical indicator of CTS. PMID:26885222

    Carpal tunnel syndrome (CTS) is a common peripheral entrapment neuropathy of the median nerve at wrist level, and is thought to be caused by compression of the median nerve in the carpal tunnel. There is no standard quantitative reference for the diagnosis of CTS. Grey-scale sonography and sonoelastography (SEL) have been used as diagnostic tools. The most commonly agreed findings in grey-scale sonography for the diagnosis of CTS is enlargement of the median nerve cross-sectional area (CSA). Several authors have assessed additional parameters. “Delta CSA” is the difference between the proximal median nerve CSA at the pronator quadratus and the maximal CSA within the carpal tunnel. The “CSA ratio” is the ratio of CSA in the carpal tunnel to the CSA at the mid forearm. These additional parameters showed better diagnostic accuracy than CSA measurement alone. Recently, a number of studies have investigated the elasticity of the median nerve using SEL, and have shown that this also has diagnostic value, as it was significantly stiffer in CTS patients compared to healthy volunteers. In this review, we summarize the usefulness of grey-scale sonography and SEL in diagnosing CTS.

    We report a case of rectal cancer with microsatellite instability (MSI) that probably resulted from Lynch syndrome and that was diagnosed after Cesarean section. The patient was a 28-year-old woman (gravid 1, para 1) without a significant medical history. At 35 gestational weeks, vaginal ultrasonography revealed a 5?cm tumor behind the uterine cervix, which was diagnosed as a uterine myoma. The tumor gradually increased in size and blocked the birth canal, resulting in the patient undergoing an emergency Cesarean section. Postoperatively, the tumor was diagnosed as rectal cancer with MSI. After concurrent chemoradiation therapy, a lower anterior resection was performed. The patient's family history revealed she met the criteria of the revised Bethesda guidelines for testing the colorectal tumor for MSI. Testing revealed that the tumor did indeed show high MSI and, combined with the family history, suggested this could be a case of Lynch syndrome. Our findings emphasize the importance of considering the possibility of Lynch syndrome in pregnant women with colorectal cancer, particularly those with a family history of this condition. We suggest that the presence of Lynch syndrome should also be considered for any young woman with endometrial, ovarian, or colorectal cancer. PMID:26064726

    2014-01-01

    Background: To diagnose chronic anterior compartment syndrome (CACS) among patients with exercise-induced leg pain, intramuscular pressure (IMP) is regarded as the gold standard. Two recent studies have suggested that the evidence for commonly used IMP criteria are weak, and the validity has therefore come under question. Purpose: To evaluate whether the amplitude of pulse-synchronous IMP oscillations at rest after an exercise test is a reliable parameter that may aid in diagnosing CACS. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: A total of 89 consecutive patients with suspected CACS (mean age, 31 years) and 19 healthy subjects (mean age, 28 years) participated in this study. All participants performed an exercise test until they were unable to continue because of leg pain and/or muscle fatigue. The IMP was recorded continuously in the anterior compartment of the leg with a noninfusion pressure recording system, starting 15 to 30 seconds after discontinuation of exercise. To test the amplitude of pulse-synchronous IMP oscillations as an indicator of CACS, a peak-to-peak amplitude of >2 mm Hg was chosen as the cutoff value. The clinical diagnosis of CACS was considered reference standard. Results: The mean ± SD IMP 1 minute after exercise was 54 ± 16 mm Hg in 53 patients with CACS, 17 ± 6 mm Hg in 36 non-CACS patients, and 18 ± 5 mm Hg in control subjects. The mean amplitude of the oscillations was 7.1 ± 3 mm Hg in patients with CACS, 1.3 ± 0.9 mm Hg in non-CACS patients, and 1.5 ± 0.6 mm Hg in control subjects 1 minute after exercise. The sensitivity of the amplitude to validate CACS was 96%, while the specificity was 94%. The positive predictive value was 96%, and the negative predictive value was 94%. Conclusion: The amplitude of the pulse-synchronous IMP oscillations at rest after an exercise test that elicits a patient’s leg pain and muscle fatigue has high sensitivity to identify an abnormally elevated IMP. Clinical Relevance: Oscillations are easily recorded during clinical routine IMP measurements. They ascertain the diagnosis of CACS, corroborate the level of IMP, and ensure catheter patency.

    Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy and is characterized by median nerve entrapment at the wrist and the resulting median nerve dysfunction. CTS is diagnosed clinically as the gold standard and confirmed with nerve conduction studies (NCS). Complementing NCS, ultrasound imaging could provide additional anatomical information on pathological and motion changes of the median nerve. The purpose of this study was to estimate the transverse sliding patterns of the median nerve during finger movements by analyzing ultrasound dynamic images to distinguish between normal subjects and CTS patients. Transverse ultrasound images were acquired, and a speckle-tracking algorithm was used to determine the lateral displacements of the median nerve in radial-ulnar plane in B-mode images utilizing the multilevel block-sum pyramid algorithm and averaging. All of the averaged lateral displacements at separate acquisition times within a single flexion-extension cycle were accumulated to obtain the cumulative lateral displacements, which were curve-fitted with a second-order polynomial function. The fitted curve was regarded as the transverse sliding pattern of the median nerve. The R2 value, curvature, and amplitude of the fitted curves were computed to evaluate the goodness, variation and maximum value of the fit, respectively. Box plots, the receiver operating characteristic (ROC) curve, and a fuzzy c-means clustering algorithm were utilized for statistical analysis. The transverse sliding of the median nerve during finger movements was greater and had a steeper fitted curve in the normal subjects than in the patients with mild or severe CTS. The temporal changes in transverse sliding of the median nerve within the carpal tunnel were found to be correlated with the presence of CTS and its severity. The representative transverse sliding patterns of the median nerve during finger movements were demonstrated to be useful for quantitatively estimating median nerve dysfunction in CTS patients.

    A fundamental role for the endosymbiotic bacteria Wolbachia pipientis in the pathogenesis of Dirofilaria immitis infections has emerged in recent years. Diagnostic opportunities arising from this breakthrough have not yet been fully exploited. This study was aimed at developing conventional and real-time PCR assays to carry out a molecular survey in a convenience sample of cats living in an area where D. immitis is endemic and to evaluate the detection of bacterial DNA in blood as a surrogate assay for diagnosing filaria-associated syndromes in cats. COI and FtsZ loci were used as targets for D. immitis and Wolbachia PCR assays, respectively, and real-time TaqMan PCR assays were used only for Wolbachia. A convenience sample of 307 disease-affected or healthy cats examined at a University facility were PCR tested, and their medical records were investigated. Conventional nested PCR for Wolbachia amplified the endosymbionts of both D. immitis and D. repens, while real-time PCR was highly specific only for the former. Observed prevalences of 0.3 and 10.4% were found using conventional nested PCR assays for D. immitis and real-time PCR for Wolbachia, respectively. Similar prevalences were established using the Wolbachia nested PCR (98% concordance with real-time PCR). The group of Wolbachia-positive samples had a significantly higher proportion of subjects with respiratory signs (29.0% versus 9.7%; P = 0.002). The findings of this study indicate that a highly sensitive PCR assay can be used to detect the Wolbachia organism in the peripheral blood of cats with respiratory signs. PMID:22649020

    The primary objective of this study was to investigate factors associated with fatigue severity in newly diagnosed patients with higher-risk myelodysplastic syndromes (MDS). The secondary objectives were to assess symptom prevalence and to examine the relationships between fatigue, quality of life (QoL) and overall symptom burden in these patients. The analyses were conducted in 280 higher-risk MDS patients. Pre-treatment patient-reported fatigue was evaluated with the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue scale and QoL was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Female gender (P=0018), poor performance status (i.e., ECOG of 2-4) (P<0001) and lower levels of haemoglobin (Hb) (P=0026) were independently associated with higher fatigue severity. The three most prevalent symptoms were as follows: fatigue (92%), dyspnoea (63%) and pain (55%). Patients with higher levels of fatigue also had greater overall symptom burdens. The mean global QoL scores of patients with the highest versus those with the lowest levels of fatigue were 292 [standard deviation (SD), 183] and 690 (SD, 188), respectively and this difference was four times the magnitude of a clinically meaningful difference. Patient-reported fatigue severity revealed the effects of disease burden on overall QoL more accurately than did degree of anaemia. Special attention should be given to the female patients in the management of fatigue. PMID:25272332

    Two brothers with presumed Baller-Gerold syndrome, one of whom was previously diagnosed with the association of vertebral, cardiac, renal, limb anomalies, anal atresia, tracheo-esophageal fistula (VACTERL) association with hydrocephalus, were evaluated for chromosome breakage because of severe thrombo cytopenia in one of them. Spontaneous and clastogen-induced breakage was markedly increased in both patients as compared to control individuals. Clinical manifestations and chromosome breakage, consistent with Fanconi anemia, in patients with a prior diagnosis of either Baller-Gerold syndrome, reported earlier in one other patient, or with VACTERL association with hydrocephalus, recently reported in 3 patients, underline the clinical heterogeneity of Fanconi anemia and raise the question of whether these syndromes are distinct disorders or phenotypic variations of the same disease. 12 refs., 3 figs., 1 tab.

    Overgrowth syndromes comprise a heterogeneous group of diseases that are characterized by excessive tissue development. Some of these syndromes may be associated with dysfunction in the receptor tyrosine kinase (RTK)/PI3K/AKT pathway, which results in an increased expression of the insulin receptor. In the current review, four overgrowth syndromes were characterized (Proteus syndrome, Klippel-Trenaunay-Weber syndrome, Madelung's disease, and neurofibromatosis type I) and illustrated using cases from our institution. Because these syndromes have overlapping clinical manifestations and have no established genetic tests for their diagnosis, radiological methods are important contributors to the diagnosis of many of these syndromes. The correlation of genetic discoveries and molecular pathways that may contribute to the phenotypic expression is also of interest, as this may lead to potential therapeutic interventions.

    Individuals from three families ascertained in Bogota, Colombia, showing syndromic phenotypes, including cleft lip and/or palate, were exome-sequenced. In each case, sequencing revealed the underlying causal variation confirming or establishing diagnoses. The findings include very rare and novel variants providing insights into genotype and phenotype relationships. These include the molecular diagnosis of an individual with Nager syndrome and a family exhibiting an atypical incontinentia pigmenti phenotype with a missense mutation in IKBKG. IKBKG mutations are typically associated with preterm male death, but this variant is associated with survival for 8-15?days. The third family exhibits unusual phenotypic features and the proband received a provisional diagnosis of Pierre Robin sequence (PRS). Affected individuals share a novel deleterious mutation in IRF6. Mutations in IRF6 cause Van der Woude and popliteal pterygium syndrome and contribute to nonsyndromic cleft lip phenotypes but have not previously been associated with a PRS phenotype. Exome sequencing followed by in silico screening to identify candidate causal variant(s), and functional assay in some cases offers a powerful route to establishing molecular diagnoses. This approach is invaluable for conditions showing phenotypic and/or genetic heterogeneity including cleft lip and/or palate phenotypes where many underlying causal genes have not been identified.

    Inborn errors of cholesterol biosynthesis caused by dysfunctionality of single enzymes are known to cause severe malformation syndromes like X-linked chondrodysplasia punctata (CDPX2), CHILD syndrome or Smith-Lemli-Opitz-syndrome (SLOS). In this study we established the method of RNA interference (RNAi) for analyzing the molecular mechanisms underlying disrupted cholesterol biosynthesis. For different genes involved in the cholesterol biosynthesis pathway-NAD(P) dependent steroid dehydrogenase-like (NSDHL), 17-beta hydroxysteroid dehydrogenase type 7 (HSD17B7) and emopamil binding protein (EBP)-shRNA sequences were designed and tested for their effectiveness. For a better comparability of the experiments and to avoid different transfection efficiencies, examined shRNA sequences which reached a knock down of at least 80% were stably transfected in a HeLa cell line with a tetracycline-regulated expression (HeLa T-REx). These stable transfected cell lines represent novel tools for the analysis of cholesterol biosynthesis. PMID:17498944

    Keutel syndrome is a rare autosomal recessive disorder, characterized by brachytelephalangia (short, broad distal phalanges), midfacial hypoplasia, abnormal cartilage calcifications, peripheral pulmonary stenosis and hearing loss. Binder profile is a well known maxillonasal dysplasia composed of midfacial hypoplasia with absence of anterior nasal spine and facial dysmophism (short nose, flat nasal bridge, perialar flatness, convex upper lip). Here we report a Keutel syndrome presenting with Binder phenotype, abnormal calcifications, hearing loss and respiratory insufficiency in the newborn period. Keutel syndrome should be considered in the differential diagnosis of children with tracheobronchial calcifications, midfacial hypoplasia and stippled epiphysis. PMID:22611639

    POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a disorder that mainly affects adults. We report a pediatric patient, initially considered to have Guillain-Barr syndrome, who continued to have progression of neuropathic disease leading to the diagnosis of chronic inflammatory demyelinating polyneuropathy. Diagnosis of POEMS was established by an abnormal bone marrow biopsy, prompted by laboratory and imaging findings, which became abnormal later in the course of the disease. POEMS syndrome is extremely rare in children, and neuropathic features in this age group have not been previously described. This case illustrates that "Guillain-Barr syndrome-like" initial presentation for POEMS, which has not been previously reported. It also emphasizes that in children with progressive acquired neuropathies that are treatment unresponsive, POEMS syndrome should be considered. PMID:26583497

    2008-03-01

    Smith-Magenis syndrome (SMS) and duplication 17p11.2 (dup17p11.2) syndrome are multiple congenital anomalies/mental retardation disorders resulting from either a deletion or duplication of the 17p11.2 region, respectively. The retinoic acid induced 1 (RAI1) gene is the causative gene for SMS and is included in the 17p11.2 region of dup17p11.2 syndrome. Currently SMS and dup17p11.2 syndrome are diagnosed using a combination of clinically recognized phenotypes and molecular cytogenetic analyses such as fluorescent in situ hybridization (FISH). However, these methods have proven to be highly expensive, time consuming, and dependent upon the low resolving capabilities of the assay. To address the need for improved diagnostic methods for SMS and dup17p11.2 syndrome, we designed a quantitative real-time PCR (Q-PCR) assay that measures RAI1 copy number using the comparative C(t) method, DeltaDeltaC(t). We tested our assay with samples blinded to their previous SMS or dup17p11.2 syndrome status. In all cases, we were able to determine RAI1 copy number status and render a correct diagnosis accordingly. We validated these results by both FISH and multiplex ligation-dependent probe amplification (MLPA). We conclude that Q-PCR is an accurate, reproducible, low-cost, and reliable assay that can be employed for routine use in SMS and dup17p11.2 diagnosis. PMID:18373405

    Purpose Diagnosing corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP) is often difficult due to the wide variety of symptoms and overlaps in the similar clinical courses and neurological findings. The purpose of this study was to evaluate the utility of white matter (WM) atrophy for the diagnosis of patients with clinically diagnosed CBD (corticobasal syndrome, CBS) and PSP (Richardsons syndrome, RS). Methods We randomly divided the 3D T1-weighted MR images of 18 CBS patients, 33 RS patients, and 32 age-matched controls into two groups. We obtained segmented WM images in the first group using Voxel-based specific regional analysis system for Alzheimers disease (VSRAD) based on statistical parametric mapping (SPM) 8 plus diffeomorphic anatomical registration through exponentiated Lie algebra. A target volume of interest (VOI) for disease-specific atrophy was subsequently determined in this group using SPM8 group analyses of WM atrophy between patients groups and controls. We then evaluated the utility of these VOIs for diagnosing CBS and RS patients in the second group. Z score values in these VOIs were used as the determinant in receiver operating characteristic (ROC) analyses. Results Specific target VOIs were determined in the bilateral frontal subcortical WM for CBS and in the midbrain tegmentum for RS. In ROC analyses, the target VOIs of CBS and RS compared to those of controls exhibited an area under curve (AUC) of 0.99 and 0.84, respectively, which indicated an adequate diagnostic power. The VOI of CBS revealed a higher AUC than that of RS for differentiating between CBS and RS (AUC, 0.75 vs 0.53). Conclusions Bilateral frontal WM volume reduction demonstrated a higher power for differentiating CBS from RS. This VOI analysis is useful for clinically diagnosing CBS and RS. PMID:26082887

    Objective. To investigate the effect of acarbose therapy on the long-term prognosis of patients with acute coronary syndromes (ACS) complicating newly diagnosed impaired glucose tolerance (IGT). Methodology. 135 patients hospitalized for ACS who had been newly diagnosed with IGT were randomly assigned to acarbose group (150 mg/day, n = 67) or control group (no acarbose, n = 68). All cases in each group were given the same elementary treatment. Mean follow-up was 2.3 years. The incidence of major adverse cardiovascular event (MACE) and carotid intima-middle thickness (CIMT) were statistically analyzed. Results. During the mean follow-up of 2.3 years, the risk of recurrent MACE in acarbose group was decreased significantly compared with that in control group (26.67% versus 46.88%, P < 0.05); at the same time, thickening of the CIMT was significantly slower than the control group ((1.28 ± 0.42) mm versus (1.51 ± 0.64) mm, P < 0.05). Conclusions. Acarbose can effectively reduce the risk of MACE in ACS patients with newly diagnosed IGT, simultaneously retarding the progression of carotid intima-media thickness. PMID:26770983

    7-Dehydrocholesterol, an immediate metabolic predecessor of cholesterol, can accumulate in tissues due to some metabolic abnormalities, causing an array of symptoms known as Smith-Lemli-Opitz syndrome. Enrichment of cellular membranes with 7-dehydrocholesterol interferes with normal cell-signaling processes, which involve interaction between rafts and formation of the so-called signaling platforms. In model membranes, cholesterol-based ordered domains usually merge upon contact. According to our experimental data, ordered domains in the model systems where cholesterol is substituted for 7-dehydrocholesterol never merge on the time scale of the experiment, but clusterize into necklace-like aggregates. We attribute such different dynamical behavior to altered properties of the domain boundary. In the framework of thickness mismatch model, we analyzed changes of interaction energy profiles of two approaching domains caused by substitution of cholesterol by 7-dehydrocholesterol. The energy barrier for domain merger is shown to increase notably, with simultaneous appearance of another distinct local energy minimum. Such energy profile is in perfect qualitative agreement with the experimental observations. The observed change of domain dynamics can impair proper interaction between cellular rafts underlying pathologies associated with deviations in cholesterol metabolism. PMID:26783730

    Smith-Lemli-Opitz syndrome (SLOS) is an autosomal recessive disorder of cholesterol biosynthesis caused by mutations in the DHCR7 gene. Previous studies estimated the prevalence of SLOS between 1 in 10,000 to 1 in 70,358 based on case frequency surveys. Although panethnic, SLOS appears to be most frequent in Central European populations (Czech Republic 1 in 10,000, Slovakia 1 in 15,000 - 1 in 20,000). In Polish individuals with SLOS two DHCR7 mutations, c.452G>A (p.Trp151X) and c.976G>T (p.Val326Leu), account for 65.2% of all observed DHCR7 mutations. We analyzed 2169 samples for the p.Trp151X mutation and 2087 for the p.Val326Leu mutation. The combined carrier frequency of these two mutations of was 2.40+/-0.32%, yielding a calculated incidence of SLOS in Poland of 2.5 4x10(-4)-4.3 5x10(-4) (1 in 2,300 to 1 in 3,937) placing SLOS among the most common recessive genetic disorders in Poland.

    Oxysterols are intermediates of cholesterol metabolism and are generated from cholesterol via either enzymatic or nonenzymatic pathways under oxidative stress conditions. Cholestan-3β,5α,6β-triol (C-triol) and 7-ketocholesterol (7-KC) have been proposed as new biomarkers for the diagnosis of Niemann-Pick type C (NP-C) disease, representing an alternative tool to the invasive and time-consuming method of fibroblast filipin test. To test the efficacy of plasma oxysterol determination for the diagnosis of NP-C, we systematically screened oxysterol levels in patients affected by different inherited disorders related with cholesterol metabolism, which included Niemann-Pick type B (NP-B) disease, lysosomal acid lipase (LAL) deficiency, Smith-Lemli-Opitz syndrome (SLOS), congenital familial hypercholesterolemia (FH), and sitosterolemia (SITO). As expected, NP-C patients showed significant increase of both C-triol and 7-KC. Strong increase of both oxysterols was observed in NP-B and less pronounced in LAL deficiency. In SLOS, only 7-KC was markedly increased, whereas in both FH and in SITO, oxysterol concentrations were normal. Interestingly, in NP-C alone, we observed that plasma oxysterols correlate negatively with patient's age and positively with serum total bilirubin, suggesting the potential relationship between oxysterol levels and hepatic disease status. Our results indicate that oxysterols are reliable and sensitive biomarkers of NP-C. PMID:26733147

    Increased plasma cholesterol concentration is associated with increased risk of cardiovascular disease. This study describes the development, validation, and analysis of a physiologically based kinetic (PBK) model for the prediction of plasma cholesterol concentrations in humans. This model was directly adapted from a PBK model for mice by incorporation of the reaction catalyzed by cholesterol ester transfer protein and contained 21 biochemical reactions and eight different cholesterol pools. The model was calibrated using published data for humans and validated by comparing model predictions on plasma cholesterol levels of subjects with 10 different genetic mutations (including familial hypercholesterolemia and Smith-Lemli-Opitz syndrome) with experimental data. Average model predictions on total cholesterol were accurate within 36% of the experimental data, which was within the experimental margin. Sensitivity analysis of the model indicated that the HDL cholesterol (HDL-C) concentration was mainly dependent on hepatic transport of cholesterol to HDL, cholesterol ester transfer from HDL to non-HDL, and hepatic uptake of cholesterol from non-HDL-C. Thus, the presented PBK model is a valid tool to predict the effect of genetic mutations on cholesterol concentrations, opening the way for future studies on the effect of different drugs on cholesterol levels in various subpopulations in silico.

  15. Cholesterol: Its Regulation and Role in Central Nervous System Disorders

    Cholesterol is a major constituent of the human brain, and the brain is the most cholesterol-rich organ. Numerous lipoprotein receptors and apolipoproteins are expressed in the brain. Cholesterol is tightly regulated between the major brain cells and is essential for normal brain development. The metabolism of brain cholesterol differs markedly from that of other tissues. Brain cholesterol is primarily derived by de novo synthesis and the blood brain barrier prevents the uptake of lipoprotein cholesterol from the circulation. Defects in cholesterol metabolism lead to structural and functional central nervous system diseases such as Smith-Lemli-Opitz syndrome, Niemann-Pick type C disease, and Alzheimer's disease. These diseases affect different metabolic pathways (cholesterol biosynthesis, lipid transport and lipoprotein assembly, apolipoproteins, lipoprotein receptors, and signaling molecules). We review the metabolic pathways of cholesterol in the CNS and its cell-specific and microdomain-specific interaction with other pathways such as the amyloid precursor protein and discuss potential treatment strategies as well as the effects of the widespread use of LDL cholesterol-lowering drugs on brain functions.

  16. The modified NCEP ATP III criteria maybe better than the IDF criteria in diagnosing Metabolic Syndrome among Malays in Kuala Lumpur

    PubMed Central

    2010-01-01

    Background Metabolic Syndrome is associated with increased risk for type 2 diabetes and cardiovascular diseases. However, different diagnostic criteria have been recommended by different expert groups. In Malaysia, there is a lack of research comparing these different diagnostic criteria. Therefore, it is our aim to study the concordance between the IDF and the modified NCEP ATP III definitions of Metabolic Syndrome among a Malay cohort in Kuala Lumpur; and to demonstrate if all participants have the same cardiometabolic risks. Methods This was an analytical cross sectional study. Ethics approval was obtained and informed consent was given by all participants. Anthropometric measurements, blood pressure, fasting blood glucose and lipid profile were taken following standard protocols. Results Metabolic Syndrome was diagnosed in 41.4% and 38.2% participants using the modified NCEP and IDF criteria respectively. Among those diagnosed with Metabolic Syndrome by modified NCEP, 7.6% were missed by the IDF criteria. Participants diagnosed by the modified NCEP criteria had lower BMI and waist circumference but had higher cardiometabolic risks than those diagnosed with both criteria. Their blood pressure, glucose, total cholesterol and triglyceride were more adverse than the IDF group. This demonstrated that central obesity may not be a prerequisite for the development of increased cardiometabolic risks within this Malay cohort. Conclusion Metabolic syndrome is common in this Malay cohort regardless of the criterion used. The modified NCEP ATP III criteria may be more suitable in diagnosis of metabolic syndrome for this Malay cohort. PMID:21054885

    A non-restrictive and non-contact respiratory movement monitoring system that finds the boundary between chest and abdomen automatically and detects the vertical movement of each part of the body separately is proposed. The system uses a fiber-grating vision sensor technique and the boundary position detection is carried out by calculating the centers of gravity of upward moving and downward moving sampling points, respectively. In the experiment to evaluate the ability to detect the respiratory movement signals of each part and to discriminate between obstructive and central apneas, detected signals of the two parts and their total clearly showed the peculiarities of obstructive and central apnea. The cross talk between the two categories classified automatically according to several rules that reflect the peculiarities was ≤ 15%. This result is sufficient for discriminating central sleep apnea syndrome from obstructive sleep apnea syndrome and indicates that the system is promising as screening equipment. Society of Japan

    Purpose To investigate the efficacy of topiramate monotherapy in West syndrome prospectively. Methods The study population included 28 patients (15 male and 13 female children aged 2 to 18 months) diagnosed with West syndrome. After a 2-week baseline period for documentation of the frequency of spasms, topiramate was initiated at 2 mg/kg/day. The dose was increased by 2 mg/kg every week to a maximum of 12 mg/kg/day. Clinical assessment was based on the parents' report and a neurological examination every 2 weeks for the first 2 months of treatment. The baseline electroencephalograms (EEGs) were compared with the post-treatment EEGs at 2 weeks and 1 month. Results West syndrome was considered to be cryptogenic in 7 of the 28 patients and symptomatic in 21 patients. After treatment, 11 patients (39%) became spasm-free, 6 (21%) had more than 50% spasmsreduction, 3 (11%) showed less than 50% reduction, and 8 (29%) did not respond. The effective daily dose for achieving more than 50% reduction in spasm frequency, including becoming spasm-free, was found to be 5.81.1 mg/kg/day. Nine patients (32%) showed complete disappearance of spasms and hypsarrhythmia, and 11 (39%) showed improved EEG results. Despite adverse events (4 instances of irritability, 3 of drowsiness, and 1 of decreased feeding), no patients discontinued the medication. Conclusion Topiramate monotherapy seems to be effective and well tolerated as a first line therapy for West syndrome and is not associated with serious adverse effects. PMID:22232631

    A 52-year-old man was found to have a severely dilated aortic root and a Stanford type A dissection on familial screening echocardiography, following diagnosis of a dilated aorta in his son. The dissection required urgent surgical repair. Clinical examination suggested features of Loeys-Dietz syndrome type II, and subsequent demonstration of a mutation in the TGFBR1 gene in the patient and his son confirmed the diagnosis. This article highlights the high prevalence of inherited conditions in dilated aortic root presentations and the importance of family screening and surveillance to allow early surgical intervention.

    Restless legs syndrome (RLS) mimics cannot always be differentiated from RLS/Willis-Ekbom disease (WED) based on 4 essential criteria; hence, a fifth criterion has recently been established. RLS comorbidities may provide us important clues for understanding the neurobiology of RLS/WED. Iron-dopamine connection, hypoxia pathway activation, and dopamine-opioid interaction are important pathophysiological mechanisms in RLS; this knowledge is derived from our understanding of RLS associations with a variety of medical, neurologic, and other conditions. Clinicians must formulate an RLS differential diagnosis based on history and physical examination, but laboratory tests may sometimes be needed to arrive at a correct diagnosis. PMID:26329435

  2. Diagnosing moral disorder: the discovery and evolution of fetal alcohol syndrome.

    Armstrong, E M

    1998-12-01

    The diagnosis of fetal alcohol syndrome (FAS) was invented in 1973. This paper investigates the process by which a cluster of birth defects associated with exposure to alcohol in utero came to be a distinct medical diagnosis, focusing on the first ten years of the medical literature on FAS. Fetal alcohol syndrome was "discovered" by a group of American dysmorphologists who published the first case reports and coined the term FAS. However, the nature of the diagnosis and its salient symptoms were determined collectively over time by the medical profession as a whole. The paper traces the natural history of the diagnosis in the U.S. through five stages: introduction, confirmation and corroboration, dissent, expansion, and diffusion. FAS serves as an example of the social construction of clinical diagnosis; moral entrepreneurship plays a key role and the medical literature on FAS is infused with moral rhetoric, including passages from classical mythology, philosophy, and the Bible. FAS is a moral as well as a medical diagnosis, reflecting the broader cultural concerns of the era in which it was discovered, including a greater awareness of environmental threats to health, the development of fetal medicine, an emphasis on "the perfect child," and a growing paradigm of maternal-fetal conflict.

    Objective To investigate the predictive value of the sympathetic skin response (SSR) in diagnosing complex regional pain syndrome (CRPS) by comparing three diagnostic modalities-SSR, three-phasic bone scans (TPBS), and thermography. Methods Thirteen patients with severe limb pain were recruited. Among them, 6 were diagnosed with CRPS according to the proposed revised CRPS clinical diagnostic criteria described by the International Association for the Study of Pain. SSR was measured in either the hands or feet bilaterally and was considered abnormal when the latency was prolonged. A positive TPBS finding was defined as diffuse increased tracer uptake on the delayed image. Thermographic findings were considered positive if a temperature asymmetry greater than 1.00? was detected between the extremities. Results Five of 6 CRPS patients showed prolonged latency on SSR (83% sensitivity). TPBS was positive in the 5 CRPS patients who underwent TPBS (100% sensitivity). Thermography was positive in 4 of 5 CRPS patients who underwent the procedure (80% sensitivity). The remaining 7 non-CRPS patients differed on examination. SSR latencies within normal limit were noted in 4 of 7 non-CRPS patients (57% specificity). Results were negative in 4 of 5 non-CRPS patients who underwent TPBS (80% specificity), and negative in 3 of 5 non-CRPS patients who underwent thermography (60% specificity). Conclusion SSR may be helpful in detecting CRPS. PMID:25750880

    Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome in which patients present with an acute or subacute clinical presentation of seizures, visual disturbances, headache, and altered mental status. The pathophysiology of PRES may be explained by endothelial dysfunction that leads to transudation of fluids and protein, resulting in vasogenic cerebral edema. PRES is typically associated with many conditions such as hypertension, uremia, immunosuppressive drugs, and sepsis. This is a case report of a 39-year-old woman with untreated HIV infection and end-stage renal disease (ESRD) who developed PRES with a normal blood pressure and no other known causes of PRES. Untreated HIV is associated with known endothelial dysfunction and we believe that this, in combination with her untreated end-stage renal disease, contributed to her unique presentation of PRES. Although uncommon in HIV-infected patients and challenging to diagnose, prompt recognition of PRES is critical to provide appropriate care and ensure reversibility of the vasogenic edema seen in PRES.

    Adult celiac disease (CD) presents with very diverse symptoms that are clearly different from those typically seen in pediatric patients, including ferropenic anemia, dyspepsia, endocrine alterations and elevated transaminase concentration. We present the case of a 51-year-old overweight woman with altered basal blood glucose, hypercholesterolemia, hypertriglyceridemia and persisting elevated transaminase levels, who showed all the symptoms for a diagnosis of metabolic syndrome. Because she presented iron deficiency anemia, she was referred to the gastroenterology department and subsequently diagnosed with celiac disease after duodenal biopsies and detection of a compatible HLA haplotype. Gluten-free diet (GFD) was prescribed and after 6 mo the patient showed resolution of laboratory abnormalities (including recovering anemia and iron reserves, normalization of altered lipid and liver function parameters and decrease of glucose blood levels). No changes in weight or waist circumference were observed and no significant changes in diet were documented apart from the GFD. The present case study is the first reported description of an association between CD and metabolic syndrome, and invites investigation of the metabolic changes induced by gluten in celiac patients.

    Abdominal compartment syndrome (ACS) and intra-abdominal hypertension (IAH) are increasingly recognized as potential complications in intensive care unit (ICU) patients. ACS and IAH affect all body systems, most notably the cardiac, respiratory, renal, and neurologic systems. ACS/IAH affects blood flow to various organs and plays a significant role in the prognosis of the patients. Recognition of ACS/IAH, its risk factors and clinical signs can reduce the morbidity and mortality associated. Moreover, knowledge of the pathophysiology may help rationalize the therapeutic approach. We start this article with a brief historic review on ACS/IAH. Then, we present the definitions concerning parameters necessary in understanding ACS/IAH. Finally, pathophysiology aspects of both phenomena are presented, prior to exploring the various facets of ACS/IAH management. PMID:21769216

    Sjgren-Larsson syndrome (SLS) is an autosomal recessively inherited neurocutaneous disorder characterized by the triad of congenital ichthyosis, mental deficiency, and spastic diplegia or tetraplegia. Less common features are retinal changes, short stature, kyphoscoliosis, preterm birth, photophobia, reduction of visual acuity, seizures, and delayed speech. SLS is characterized by a genetic block in the oxidation of fatty alcohol to fatty acid because of deficient activity of fatty aldehyde dehydrogenase (FALDH), a component of the fatty alcohol: NAD oxidoreductase enzyme complex. As in other rare multisystem diseases, the diagnosis of SLS is often delayed. The definitive test for SLS is considered the measurement of FALDH or fatty alcohol: NAD oxidoreductase in cultured skin fibroblasts. Nevertheless, if specific FALDH activity test or DNA FALDH gene mutation tests are not available (as in our country), a reliable diagnosis of SLS is also possible when it is based on the matching of peculiar clinical, histologic and ultrastructural, laboratoristic, and imaging features. The simultaneous presence of cutaneous histologic features including hyperkeratosis, orthokeratosis, thickening of granular layer, abnormal lamellar inclusions in the cytoplasm of granular and horny cells (demonstrated by light and electron microscopy) in a child with ichthyosis, and typical neurologic abnormalities is highly suggestive of SLS. We describe the case of a young Moroccan boy presenting with ichthyosis, mental retardation, spastic diplegia, and peculiar skin histologic findings. PMID:17302612

    Papillon-Lefvre syndrome (PLS) (OMIM: 245000) is a rare disease characterized by severe periodontitis and palmoplantar keratoderma. It is caused by mutations in both alleles of the cathepsin C (CatC) gene CTSC that completely abrogate the proteolytic activity of this cysteine proteinase. Most often, a genetic analysis to enable early and rapid diagnosis of PLS is unaffordable or unavailable. In this study, we tested the hypothesis that active CatC is constitutively excreted and can be easily traced in the urine of normal subjects. If this is true, determining its absence in the urine of patients would be an early, simple, reliable, low-cost and easy diagnostic technique. All 75 urine samples from healthy control subjects (aged 3 months to 80 years) contained proteolytically active CatC and its proform, as revealed by kinetic analysis and immunochemical detection. Of the urine samples of 31 patients with a PLS phenotype, 29 contained neither proteolytically active CatC nor the CatC antigen, so that the PLS diagnosis was confirmed. CatC was detected in the urine of the other two patients, and genetic analysis revealed no loss-of-function mutation in CTSC, indicating that they suffer from a PLS-like condition but not from PLS. Screening for the absence of urinary CatC activity soon after birth and early treatment before the onset of PLS manifestations will help to prevent aggressive periodontitis and loss of many teeth, and should considerably improve the quality of life of PLS patients.

    Over the past 9 years we counseled 55 couples whose unborn child was found to carry a sex chromosome polysomy. We performed a survey of postcounseling parental decisions about continuation or termination of these pregnancies. Of the 55 embryos or fetuses, 23 had the karyotype 47,XXY, 10 had 47,XYY, and 12 had 47,XXX. In addition, there were 10 instances of true mosaicism, i.e. 47,XXY/46,XY (n = 5), 47,XYY/46,XY (n = 2), or 47,XXX/46,XX (n = 3). Mean gestational age (+/-standard deviation) at diagnosis was 18.3+/-3.0 weeks. After comprehensive genetic counseling 48 (87.3%) of these pregnancies were carried to term. In seven cases (12.7%) the parents elected a pregnancy termination. Two of 31 pregnancies (6.5%) primarily ascertained at our center were aborted, whereas amongst the 24 referred cases, 5 couples (20.8%) opted for a termination. The mean gestational age of the terminated pregnancies was 19.7 weeks. The overall termination rate of 12.7% appears low in comparison with literature data. Most reports from other institutions present termination rates between 32 and 66%. The reason for the low rate of induced abortions in our study cohort is not clear. Cultural differences in parental perception of sex chromosomal polysomies may be of importance, and peculiarities of genetic counseling at our institution could also play a role. Although counseling was nondirective, we did put emphasis on providing prospective parents with information from unbiased follow-up studies of children with Klinefelter syndrome and other sex chromosome polysomies.

    Coffin-Siris syndrome (CSS) and Nicolaides-Baraitser syndrome (NCBRS) are rare intellectual disability/congenital malformation syndromes that represent distinct entities but show considerable clinical overlap. They are caused by mutations in genes encoding members of the BRG1- and BRM-associated factor (BAF) complex. However, there are a number of patients with the clinical diagnosis of CSS or NCBRS in whom the causative mutation has not been identified. In this study, we performed trio-based whole-exome sequencing (WES) in ten previously described but unsolved individuals with the tentative diagnosis of CSS or NCBRS and found causative mutations in nine out of ten individuals. Interestingly, our WES analysis disclosed overlapping differential diagnoses including Wiedemann-Steiner, Kabuki, and Adams-Oliver syndromes. In addition, most likely causative de novo mutations were identified in GRIN2A and SHANK3. Moreover, trio-based WES detected SMARCA2 and SMARCA4 deletions, which had not been annotated in a previous Haloplex target enrichment and next-generation sequencing of known CSS/NCBRS genes emphasizing the advantages of WES as a diagnostic tool.

  12. Serum proteomic analysis identifies sex-specific differences in lipid metabolism and inflammation profiles in adults diagnosed with Asperger syndrome

    PubMed Central

    2014-01-01

    Background The higher prevalence of Asperger Syndrome (AS) and other autism spectrum conditions in males has been known for many years. However, recent multiplex immunoassay profiling studies have shown that males and females with AS have distinct proteomic changes in serum. Methods Here, we analysed sera from adults diagnosed with AS (males = 14, females = 16) and controls (males = 13, females = 16) not on medication at the time of sample collection, using a combination of multiplex immunoassay and shotgun label-free liquid chromatography mass spectrometry (LC-MSE). The main objective was to identify sex-specific serum protein changes associated with AS. Results Multiplex immunoassay profiling led to identification of 16 proteins that were significantly altered in AS individuals in a sex-specific manner. Three of these proteins were altered in females (ADIPO, IgA, APOA1), seven were changed in males (BMP6, CTGF, ICAM1, IL-12p70, IL-16, TF, TNF-alpha) and six were changed in both sexes but in opposite directions (CHGA, EPO, IL-3, TENA, PAP, SHBG). Shotgun LC-MSE profiling led to identification of 13 serum proteins which had significant sex-specific changes in the AS group and, of these, 12 were altered in females (APOC2, APOE, ARMC3, CLC4K, FETUB, GLCE, MRRP1, PTPA, RN149, TLE1, TRIPB, ZC3HE) and one protein was altered in males (RGPD4). The free androgen index in females with AS showed an increased ratio of 1.63 compared to controls. Conclusion Taken together, the serum multiplex immunoassay and shotgun LC-MSE profiling results indicate that adult females with AS had alterations in proteins involved mostly in lipid transport and metabolism pathways, while adult males with AS showed changes predominantly in inflammation signalling. These results provide further evidence that the search for biomarkers or novel drug targets in AS may require stratification into male and female subgroups, and could lead to the development of novel targeted treatment approaches.

    The diagnoses Porcine Epidemic Abortion and Respiratory Syndrome (PEARS)-positive and PEARS-negative can be made using the following data on herd performance: the average number of stillborn piglets per litter, the average number of live piglets per litter and the average piglet mortality before weaning. Depending on the number of litters used in calculating the averages, the extent to which two out of the three performance data should deviate to arrive at the diagnosis PEARS-positive is given in tables and figures. The same farm will only be diagnosed PEARS-negative if after some time at least two out of the three performance data deviate less than other criteria also provided in tables and figures.

    Background. We experienced a rare case of a pregnant woman with Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the uterus. This is the first report on the usefulness of dynamic contrast-enhanced-MRI for the diagnosis of diffuse venous malformation of the uterus. Case Presentation. A 23-year-old woman presented with convulsions and talipes equinus position of both lower limbs at 11 weeks of gestation. At 27 weeks, ultrasonography demonstrated tubular echolucent spaces throughout the myometrium. Dynamic MRI at 37 weeks revealed that the myometrial lesion was enhanced slowly and showed homogeneous enhancement even on a 10 min delayed image. Taken together with unilateral foot hypertrophy, varices, and port-wine stain, the patient was diagnosed as having Klippel-Trénaunay syndrome complicated with diffuse venous malformation of the pregnant uterus. The patient underwent elective cesarean section because of severe dystonia. The lower uterine segment was thickened and heavy venous blood flow was observed at the incision. Histological diagnosis of the myometrial biopsy specimen was venous malformation. Conclusions. Both diffuse venous malformation and Klippel-Trénaunay syndrome during pregnancy can involve considerable complications, in particular, massive bleeding during labor. Women who suffer from this syndrome should be advised about the risk of complications of pregnancy. PMID:27006845

  15. Role of a Disordered Steroid Metabolome in the Elucidation of Sterol and Steroid Biosynthesis

    PubMed Central

    2013-01-01

    In 1937 Butler and Marrian found large amounts of the steroid pregnanetriol in urine from a patient with the adrenogenital syndrome, a virilizing condition known to be caused by compromised adrenal secretion even in this pre-cortisol era. This introduced the concept of the study of altered excretion of metabolites as an in vivo tool for understanding sterol and steroid biosynthesis. This approach is still viable and has experienced renewed significance as the field of metabolomics. From the first cyclized sterol lanosterol to the most downstream product estradiol, there are probably greater than 30 steps. Based on a distinctive metabolome clinical disorders have now been attributed to about seven post-squalene cholesterol (C) biosynthetic steps and around 15 en-route to steroid hormones or needed for further metabolism of such hormones. Forty years ago it was widely perceived that the principal steroid biosynthetic defects were known but interest rekindled as novel metabolomes were documented. In his career this investigator has been involved in the study of many steroid disorders, the two most recent being P450 oxidoreductase deficiency and apparent cortisone reductase deficiency. These are of interest as they are due not to mutations in the primary catalytic enzymes of steroidogenesis but in ancillary enzymes needed for co-factor oxido-reduction A third focus of this researcher is Smith-Lemli-Opitz syndrome (SLOS), a cholesterol synthesis disorder caused by 7-dehydrocholesterol reductase mutations. The late George Schroepfer, in whose honor this article has been written, contributed greatly to defining the sterol metabolome of this condition. Defining the cause of clinically severe disorders can lead to improved treatment options. We are now involved in murine gene therapy studies for SLOS which, if successful could in the future offer an alternative therapy for this severe condition. PMID:21874273

  16. Defects in cholesterol synthesis genes in mouse and in humans: lessons for drug development and safer treatments.

    This review describes the mouse knockout models of cholesterol synthesis, together with human malformations and drugs that target cholesterogenic enzymes. Generally, the sooner a gene acts in cholesterol synthesis, the earlier the phenotype occurs. Humans with loss of function of early cholesterogenic enzymes have not yet been described, and in the mouse, loss of Hmgcr is preimplantation lethal. Together, these results indicate that the widely prescribed cholesterol-lowering statins are potentially teratogenic. The Mvk knockout is early embryonic lethal in the mouse, the absence of Fdft1 is lethal at E9.5-12.5 dpc, while the Cyp51 knockouts die at 15.0 dpc. Fungal CYP51 inhibitor azoles are teratogenic in humans, potentially leading to symptoms of Antley-Bixler syndrome. The X-linked mutations in Nsdhl and Ebp are embryonic lethal in male mice, while heterozygous females are also affected. Consequently, the anticancer drugs, tamoxifen and toremifene, inhibiting human EBP, may be harmful in early pregnancy. The Dhcr7 and Dhcr24 knockout mice die shortly after birth, while humans survive with Smith-Lemli-Opitz syndrome or desmosterolosis. Since cholesterol is essential for hedgehog signaling, disturbance of this pathway by antipsychotics and -depressants explains some drug side effects. In conclusion, defects in cholesterol synthesis are generally lethal in mice, while humans with impaired later steps of the pathway can survive with severe malformations. Evidence shows that drugs targeting or, by coincidence, inhibiting human cholesterol synthesis are better avoided in early pregnancy. Since some drugs with teratogenic potential still stay on the market, this should be avoided in new cholesterol-related drug development. PMID:21247357

    Background Prompt diagnosis of acute myocardial infarction or acute coronary syndrome is very important. Aim A systematic review was conducted to determine the accuracy of 10 important signs and symptoms in selected and non-selected patients. Design of study Diagnostic meta-analysis. Method Using MEDLINE, CINAHL, EMBASE, tracing references, and by contacting experts, studies were sought out that described one of the 10 signs and symptoms on one or both conditions. Studies were excluded if they were not based on original data. Validity was assessed using QUADAS and all data were pooled using a random effects model. Results Sixteen of the 28 included studies were about patients who were non-selected. In this group, absence of chest-wall tenderness on palpation had a pooled sensitivity of 92% (95% confidence interval [CI] = 86 to 96) for acute myocardial infarction and 94% (95% CI = 91 to 96) for acute coronary syndrome. Oppressive pain followed with a pooled sensitivity of 60% (95% CI = 55 to 66) for acute myocardial infarction. Sweating had the highest pooled positive likelihood ratio (LR+), namely 2.92 (95% CI = 1.97 to 4.23) for acute myocardial infarction. The other pooled LR+ fluctuated between 1.05 and 1.49. Negative LRs (LR?) varied between 0.98 and 0.23. Absence of chest-wall tenderness on palpation had a LR? of 0.23 (95% CI = 0.18 to 0.29). Conclusions Based on this meta-analysis it was not possible to define an important role for signs and symptoms in the diagnosis of acute myocardial infarction or acute coronary syndrome. Only chest-wall tenderness on palpation largely ruled out acute myocardial infarction or acute coronary syndrome in low-prevalence settings. PMID:18307844

    CYP11A1, found only in vertebrates, catalyzes the first step of steroidogenesis where cholesterol is converted to pregnenolone. The purified enzyme, also converts desmosterol and plant sterols including campesterol and ?-sitosterol, to pregnenolone. Studies, initially with purified enzyme, reveal that 7-dehydrocholesterol (7DHC), ergosterol, lumisterol 3, and vitamins D3 and D2 also serve as substrates for CYP11A1, with 7DHC being better and vitamins D3 and D2 being poorer substrates than cholesterol. Adrenal glands, placenta, and epidermal keratinocytes can also carry out these conversions and 7-dehydropregnenolone has been detected in the epidermis, adrenal glands, and serum, and 20-hydroxyvitamin D3 was detected in human serum and the epidermis. Thus, this metabolism does appear to occur in vivo, although its quantitative importance and physiological role remain to be established. CYP11A1 action on 7DHC in vivo is further supported by detection of ?(7)steroids in Smith-Lemli-Opitz syndrome patients. The activity of CYP11A1 is affected by the structure of the substrate with sterols having steroidal or ?(7)-steroidal structures undergoing side chain cleavage following hydroxylations at C22 and C20. In contrast, metabolism of vitamin D involves sequential hydroxylations that start at C20 but do not lead to cleavage. Molecular modeling using the crystal structure of CYP11A1 predicts that other intermediates of cholesterol synthesis could also serve as substrates for CYP11A1. Finally, CYP11A1-derived secosteroidal hydroxy-derivatives and ?(7)steroids are biologically active when administered in vitro in a manner dependent on the structure of the compound and the lineage of the target cells, suggesting physiological roles for these metabolites. This article is part of a special issue entitled 'SI: Steroid/Sterol signaling'. PMID:25448732

They usually present late with primary amenorrhea but delayed diagnosis increases chance of gonadal malignancy. Alertness for this entity is crucial as with early diagnosis such disorder can be managed more appropriately for a better future. We hereby describe a case of CAIS in an 8-year-old girl presented with bilateral inguinal swellings. Endocrinological analysis, radiological investigations and cytogenetic studies were done. Investigations revealed absence of female internal genitalia. Karyotyping and molecular study confirmed the presence of Y chromosome.

    Since a previous report on two Prader-Willi syndrome (PWS) patients with t(15q;15q) was erroneous, the authors report new data and a corrected interpretation. Reexamination of the parental origin of their t(15q;15q) using polymorphic DNA markers that are mapped to various regions of 15q documented no molecular deletions at the 15q11-q13 region in either patient. Both patients were homozygous at all loci examined and their haplotypes on 15q coincided with one of those in their respective mothers. These results indicate that the presumed t(15q;15q) in each patient was actually an isochromosome 15q producing maternal uniparental disomy, consistent with genomic imprinting at the PWS locus. 30 refs., 1 fig., 3 tabs.

    The ability to place the hands to the floor forms part of the assessment of joint hypermobility. The test may be symptom free, or in the case of joint hypermobility syndrome, may be associated with pain in the spine, hip, and knee. The aim of this study was to identify the relative amount of movement at the lumbar spine and hip during this test in people with asymptomatic and symptomatic hypermobility compared with a control group. Thirty-six female subjects (10 asymptomatic hypermobility, 13 symptomatic hypermobility, and 13 control) ranging between 18 and 60 years of age participated in the investigation. Measurements were made by using digital photography and inclinometers. Measurement reliability was established prior to the investigation. There was a significant difference (p<0.05) between hip flexion range in the two hypermobility groups compared to the control group; there was no significant difference in lumbar spine movement between the three groups. The findings suggest that people with asymptomatic or symptomatic hypermobility perform the hand to floor test with the same relative contribution from the lumbar spine and hip joints. Both groups perform the hands to floor test and with a greater relative hip flexion range than a control group. PMID:18300104

    Prion protein gene mutations have been associated with clinical pictures mimicking neurodegenerative diseases different from inherited prion diseases (IPD). We report a novel missense P39L mutation in the N-terminal domain of prion protein in 2 patients affected by frontotemporal lobar degeneration syndrome, negative for mutations in genes causative of dementia. Neither the first carrier, a 67-year-old male in which the onset was a progressive non-fluent aphasia, nor the second carrier, a 78-year-old male affected by frontotemporal dementia and parkinsonism, showed any clinical or instrumental findings suggestive of IPD. Genetic screening of healthy controls and in silico analysis provide support for the potential pathogenicity of this variant. Patient phenotypes, unclassifiable as prion disease, may depend on the location of the mutation in the N-terminal domain, outside the amyloid core of pathologic prion protein, although further functional studies are required to determine whether and how this mutation exerts its pathogenic effect. However, genetic screening of prion protein gene becomes relevant in familial degenerative dementia, particularly in geographical areas with high IPD prevalence. PMID:25022973

    We describe a male patient with dual genetic diagnoses of atypical hand-foot-genital syndrome (HFGS) and developmental delay. The proband had features of HFGS that included bilateral vesicoureteric junction obstruction with ectopic ureters, brachydactyly of various fingers and toes, hypoplastic thenar eminences, and absent nails on both 4th toes and right 5th toe. The atypical features of HFGS present were bilateral hallux valgus malformations and bilateral preaxial polydactyly of the hands. Chromosomal microarray analysis identified a de novo 0.5?Mb deletion at 2p16.3, including the first four exons of the NRXN1 gene. Whole exome sequencing and subsequent Sanger sequencing identified a de novo missense mutation (c.1123G>T, p.Val375Phe) in exon 2 of the HOXA13 gene, predicted to be damaging and located in the homeobox domain. The intragenic NRXN1 deletion is thought to explain his developmental delay via a separate genetic mechanism. 2015 Wiley Periodicals, Inc. PMID:26590955

    Varying estimates of the cost-effectiveness of genomic testing applications can reflect differences in study questions, settings, methods and assumptions. This review compares recently published cost-effectiveness analyses of testing strategies for Lynch Syndrome (LS) in tumors from patients newly diagnosed with colorectal cancer (CRC) for either all adult patients or patients up to age 70 along with cascade testing of relatives of probands. Seven studies published from 2010 through 2015 were identified and summarized. Five studies analyzed the universal offer of testing to adult patients with CRC and two others analyzed testing patients up to age 70; all except one reported incremental cost-effectiveness ratios (ICERs) < $ 100,000 per life-year or quality-adjusted life-year gained. Three studies found lower ICERs for selective testing strategies using family history-based predictive models compared with universal testing. However, those calculations were based on estimates of sensitivity of predictive models derived from research studies, and it is unclear how sensitive such models are in routine clinical practice. Key model parameters that are influential in ICER estimates included 1) the number of first-degree relatives tested per proband identified with LS and 2) the cost of gene sequencing. Others include the frequency of intensive colonoscopic surveillance, the cost of colonoscopy, and the inclusion of extracolonic surveillance and prevention options. PMID:26473097

    In cases with otherwise clinically typical Guillain-Barr syndrome (GBS), pronounced cerebrospinal fluid (CSF) pleocytosis or the mere presence of CSF-polymorphonuclear granulocytes should alert the physician to consider alternative diagnoses. Therefore, we retrospectively studied the neuropathology of central and peripheral nervous system in two cases with a CSF cell count of more than 50/microl and in three cases with a significant proportion of polymorphonuclear granulocytes in the CSF sediment. All cases fulfilled the required criteria for the diagnosis of GBS, the duration from onset to death ranged from 4 to 100 days. Neuropathological investigations included routine staining procedures and immunohistochemistry for antigens of glial and haematopoetic cells as well as for products of relevant neurotropic viruses. Demyelinating polyradiculitis was present in four cases, in one patient with a survival time of 4 days the type of damage to myelinated fibres was unclassifiable. In the central nervous system a consistent finding was diffuse activation of microglia, only one case showed mild meningeal and lower brainstem inflammation. Viral products were generally absent. In summary, the neuropathological findings confirm that marked CSF pleocytosis or the presence of polymorphonuclear granulocytes does not rule out the diagnosis of GBS. PMID:12940826

    Encephalitozoon hellem is a recently described microsporidian associated with an expanding spectrum of clinical presentations in patients with the acquired immunodeficiency syndrome (AIDS). It is morphologically similar to Encephalitozoon cuniculi, a microsporidian infection of mammals and some avians, and their differentiation rests on biochemical and antigenic analyses. This report describes a patient previously diagnosed with keratoconjunctivitis due to E hellem who subsequently was found to have respiratory tract microsporidiosis by sputum cytology. He subsequently developed pulmonary symptoms and a left lower lobe interstitial infiltrate. A bronchoalveolar lavage and transbronchial biopsy revealed microsporidial bronchiolitis, and the etiologic agent was identified as E hellem using an immunofluorescent antibody technique. Lavage fluid was successfully cultured in monkey kidney cells, and cultivated E hellem organisms were studied using immunohistochemistry as well as scanning and transmission electron microscopy. The pathologic features of this newly described cause of protozoal bronchiolitis, the role of immunofluorescent antibody examination and in vitro tissue culture for species-specific diagnosis, and the significance of microsporidial pulmonary infections in AIDS patients are discussed.

    Polycystic ovary syndrome (PCOS) women are more insulin resistant than general population. Prevalence data on insulin resistance (IR) in PCOS vary depending on population characteristics and methodology used. The objectives of this study were to investigate whether IR in PCOS is exclusively associated with body mass and to assess the prevalence of IR in lean and overweight/obese PCOS. Study included 250 consecutive women who attended a Department of Human Reproduction diagnosed as having PCOS according to the Rotterdam criteria. Control group comprised 500 healthy women referred for male factor infertility evaluation during the same period as the PCOS women. PCOS women (n = 250) were more insulin resistant than controls (n = 500) even after adjustment for age and body mass index (BMI) (P = 0.03). Using logistic regression analysis, BMI ? 25 kg/m(2) (OR 6.0; 95 % CI 3.3-11.0), PCOS (OR 2.2; 95 % CI 1.4-3.5) and waist circumference ? 80 cm (OR 2.0; 95 % CI 1.1-3.8) were identified as independent determinants of IR (P < 0.001). IR was more prevalent in overweight/obese controls (n = 100) than in lean PCOS women (n = 150), 31 versus 9.3 %, but less prevalent than in overweight/obese PCOS (n = 100), 31 versus 57 %. The prevalence of IR between lean controls (5 %) and lean PCOS (9.3 %) did not significantly differ. Both PCOS-specific and obesity-related IR independently contribute to IR in PCOS. Using HOMA-IR cutoff value of 3.15 specific for Croatian women in our clinical setting, the assessed prevalence of IR in lean and overweight/obese PCOS women was 9.3 and 57 %, respectively.

    Complex karyotypes are seen in approximately 20% of patients with myelodysplastic syndromes (MDS) and are associated with a high risk of transformation to acute myeloid leukemia and poor outcomes in patients. Copy number neutral loss of heterozygosity (CN-LOH, i.e., both copies of a chromosomal pair or their parts originate from one parent) might contribute to increased genomic instability in the bone-marrow cells of patients with MDS. The pathological potential of CN-LOH, which arises as a clonal aberration in a proportion of somatic cells, consists of tumor suppressor gene and oncogene homozygous mutations. The aim of our study was to evaluate the frequency of CN-LOH at 17p in bone-marrow cells of newly diagnosed MDS patients with complex chromosomal aberrations and to assess its correlation with mutations in the TP53 gene (17p13.1). CN-LOH was detected in 40 chromosomal regions in 21 (29%) of 72 patients analyzed. The changes in 27 of the 40 regions identified were sporadic. The most common finding was CN-LOH of the short arm of chromosome 17, which was detected in 13 (18%) of 72 patients. A mutational analysis confirmed the homozygous mutation of TP53 in all CN-LOH 17p patients, among which two frameshift mutations are not registered in the International Agency for Research on Cancer TP53 Database. CN-LOH 17p correlated with aggressive disease (median overall survival 4 months) and was strongly associated with a complex karyotype in the cohort studied, which might cause rapid disease progression in high-risk MDS. No other CN-LOH region previously recorded in MDS or AML patients (1p, 4q, 7q, 11q, 13q, 19q, 21q) was detected in our cohort of patients with complex karyotype examined at the diagnosis of MDS. The LOH region appeared to be balanced (i.e., with no DNA copy number change) when examined with conventional and molecular cytogenetic methods. Therefore, a microarray that detects single-nucleotide polymorphisms is an ideal method with which to identify and further characterize CN-LOH. Our data should specify the prognosis and should lead to the identification of potential targets for therapeutic interventions. PMID:26851439

    Abstract Objective To highlight the 2015 Canadian Hypertension Education Program (CHEP) recommendations for the diagnosis and assessment of hypertension. Quality of evidence A systematic search was performed current to August 2014 by a Cochrane Collaboration librarian using the MEDLINE and PubMed databases. The search results were critically appraised by the CHEP subcommittee on blood pressure (BP) measurement and diagnosis, and evidence-based recommendations were presented to the CHEP Central Review Committee for independent review and grading. Finally, the findings and recommendations were presented to the Recommendations Task Force for discussion, debate, approval, and voting. The main recommendations are based on level II evidence. Main message Based on the most recent evidence, CHEP has made 4 recommendations in 2 broad categories for 2015 to improve BP measurement and the way hypertension is diagnosed. A strong recommendation is made to use electronic BP measurement in the office setting to replace auscultatory BP measurement. For patients with elevated office readings, CHEP is recommending early use of out-of-office BP measurement, preferably ambulatory BP measurement, in order to identify early in the process those patients with white-coat hypertension. Conclusion Improvements in diagnostic accuracy are critical to optimizing hypertension management in Canada. The annual updates provided by CHEP ensure that practitioners have up-to-date evidence-based information to inform practice. PMID:26564654

  19. Inborn errors of cholesterol biosynthesis.

    PubMed

    Kelley, R I

    2000-01-01

    Disorders of cholesterol biosynthesis have recently emerged as important errors of metabolism that collectively have taught us many new genetic and biochemical lessons. Whereas most metabolic diseases are characterized by exclusively or largely postnatal biochemical toxicities or deficiencies, disorders of cholesterol biosynthesis are notable for their severe effects on prenatal development. The remarkable embryonic consequences of abnormal cholesterol biosynthesis are exemplified by Smith-Lemli-Opitz syndrome (SLOS), a well-known multiple congenital anomaly syndrome only recently discovered to be caused by a deficiency in the last step in cholesterol biosynthesis. Equally surprising has been the discovery that primary defects of cholesterol biosynthesis cause several different forms of congenital skeletal dysplasia, most notably X-linked dominant chondrodysplasia punctata, or Conradi-Hnermann syndrome. Yet another sterol disorder, desmosterolosis, caused by defective activity of desmosterol reductase, combines a severe osteosclerotic skeletal dysplasia with multiple embryonic malformations similar to those of SLOS. The discovery of the biochemical basis of these diverse genetic disorders has provided not only accurate biochemical methods for their diagnosis and prenatal diagnosis, but also new insights into the biochemistry of vertebrate embryonic development. Among the lessons we have learned from the study of inborn errors of cholesterol biosynthesis, one of the most important is that the abnormal cholesterol metabolism of SLOS impairs the function of "Sonic hedgehog" and other related embryonic "signaling proteins" that help determine the vertebrate body plan during the earliest weeks of embryonic development. Most significant clinically has been the realization that many of the postnatal clinical problems of patients with SLOS are direct consequences of the inability to synthesize the large amounts of cholesterol needed for growth and for the synthesis of compounds derived from cholesterol, such as steroid hormones. In addition to the important finding that supplementary cholesterol eliminates or ameliorates many of the feeding and growth problems of SLOS, the discovery that the autistic behaviors of children with SLOS can be reduced or even eliminated by treatment with supplementary dietary cholesterol has been one of the most startling. Moreover, clinical and basic research on prenatal cholesterol nutrition in SLOS and various animal model systems has delineated a previously unrecognized system for the delivery of low-density lipoprotein cholesterol from the mother to the developing embryo. The many discoveries engendered by these experiments of nature argue that there are heretofore unrecognized beneficial effects of cholesterol, especially in children, and that we should consider very carefully possible adverse effects that the popular war against cholesterol may have on the prenatal and postnatal development of children.

  20. Genetically induced abnormal cranial development in human trisomy 18 with holoprosencephaly: comparisons with the normal tempo of osteogenic-neural development.

    Craniofacial malformations are common congenital defects caused by failed midline inductive signals. These midline defects are associated with exposure of the fetus to exogenous teratogens and with inborn genetic errors such as those found in Down, Patau, Edwards' and Smith-Lemli-Opitz syndromes. Yet, there are no studies that analyze contributions of synchronous neurocranial and neural development in these disorders. Here we present the first in-depth analysis of malformations of the basicranium of a holoprosencephalic (HPE) trisomy 18 (T18; Edwards' syndrome) fetus with synophthalmic cyclopia and alobar HPE. With a combination of traditional gross dissection and state-of-the-art computed tomography, we demonstrate the deleterious effects of T18 caused by a translocation at 18p11.31. Bony features included a single developmentally unseparated frontal bone, and complete dual absence of the anterior cranial fossa and ethmoid bone. From a superior view with the calvarium plates removed, there was direct visual access to the orbital foramen and hard palate. Both the eyes and the pituitary gland, normally protected by bony structures, were exposed in the cranial cavity and in direct contact with the brain. The middle cranial fossa was shifted anteriorly, and foramina were either missing or displaced to an abnormal location due to the absence or misplacement of its respective cranial nerve (CN). When CN development was conserved in its induction and placement, the respective foramen developed in its normal location albeit with abnormal gross anatomical features, as seen in the facial nerve (CNVII) and the internal acoustic meatus. More anteriorly localized CNs and their foramina were absent or heavily disrupted compared with posterior ones. The severe malformations exhibited in the cranial fossae, orbital region, pituitary gland and sella turcica highlight the crucial involvement of transcription factors such as TGIF, which is located on chromosome 18 and contributes to neural patterning, in the proper development of neural and cranial structures. Our study of a T18 specimen emphasizes the intricate interplay between bone and brain development in midline craniofacial abnormalities in general. PMID:26018729

    Puumala virus (PUUV) is considered a classic Old World etiologic agent of nephropathia epidemica (NE), or hemorrhagic fever with renal syndrome (HFRS). HFRS is considered to be distinct from hantavirus (cardio-)pulmonary syndrome (HPS or HCPS), described in the New World. Here, we report a severe case, which fulfilled most, if not all, Centers for Disease Control and Prevention (CDC) criteria for HPS, needing non-invasive ventilation and subsequent acute hemodialysis. However, the etiological agent was PUUV, as proved by serological testing, real-time polymerase chain reaction (PCR), and sequencing. Viral antigen was detected by specific anti-PUUV immunostaining, showing, for the first time, greenish intracytoplasmic inclusions in bronchoalveolar lavage (BAL) macrophages. This case definitely confirms that HPS can be encountered during PUUV infections. Interestingly, special findings could render the diagnosis easier, such as greenish homogeneous cytoplasmic inclusions, surrounded by a fine clear halo in BAL macrophages. Therefore, although the diagnosis remains difficult before the onset of renal involvement, the occurrence of severe respiratory failure mimicking community-acquired pneumonia must alert the clinician for possible HPS, especially in endemic areas.

    Decitabine may open the chromatin structure of leukemia cells making them accessible to the calicheamicin epitope of gemtuzumab ozogamicin (GO). A total of 110 patients (median age 70 years; range 27-89 years) were treated with decitabine and GO in a trial designed on model-based futility to accommodate subject heterogeneity: group 1: relapsed/refractory acute myeloid leukemia (AML) with complete remission duration (CRD) <1 year (N=28, 25%); group 2: relapsed/refractory AML with CRD ?1 year (N=5, 5%); group 3: untreated AML unfit for intensive chemotherapy or untreated myelodysplastic syndrome (MDS) or untreated myelofibrosis (MF; N=57, 52%); and group 4: AML evolving from MDS or relapsed/refractory MDS or MF (N=20, 18%). Treatment consisted of decitabine 20?mg/m(2) daily for 5 days and GO 3?mg/m(2) on day 5. Post-induction therapy included five cycles of decitabine+GO followed by decitabine alone. Complete remission (CR)/CR with incomplete count recovery was achieved in 39 (35%) patients; group 1= 5/28 (17%), group 2=3/5 (60%), group 3=24/57 (42%) and group 4=7/20 (35%). The 8-week mortality in groups 3 and 4 was 16% and 10%, respectively. Common drug-related adverse events included nausea, mucositis and hemorrhage. Decitabine and GO improved the response rate but not overall survival compared with historical outcomes in untreated AML ?60 years. PMID:26365212

    Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is an autosomal recessive lysosomal storage disorder resulting from a deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS) activity. Diagnosis can be challenging and requires agreement of clinical, radiographic, and laboratory findings. A group of biochemical genetics laboratory directors and clinicians involved in the diagnosis of MPS IVA, convened by BioMarin Pharmaceutical Inc., met to develop recommendations for diagnosis. The following conclusions were reached. Due to the wide variation and subtleties of radiographic findings, imaging of multiple body regions is recommended. Urinary glycosaminoglycan analysis is particularly problematic for MPS IVA and it is strongly recommended to proceed to enzyme activity testing even if urine appears normal when there is clinical suspicion of MPS IVA. Enzyme activity testing of GALNS is essential in diagnosing MPS IVA. Additional analyses to confirm sample integrity and rule out MPS IVB, multiple sulfatase deficiency, and mucolipidoses types II/III are critical as part of enzyme activity testing. Leukocytes or cultured dermal fibroblasts are strongly recommended for enzyme activity testing to confirm screening results. Molecular testing may also be used to confirm the diagnosis in many patients. However, two known or probable causative mutations may not be identified in all cases of MPS IVA. A diagnostic testing algorithm is presented which attempts to streamline this complex testing process. PMID:23371450

    2015-01-01

    Introduction Neuroblastoma (NB), Hirschsprung disease (HSCR), Congenital Central Hypoventilation Syndrome (CCHS), clinically referred as the NB-HSCR-CCHS cluster, are genetic disorders linked to mutations in the PHOX2B gene on chromosome 4p12. Specific Aim The specific aim of this project is to define the PHOX2B gene mutations as the genomic basis for the clinical manifestations of the NB-HSCR-CCHS cluster. Patient A one day old male patient presented to the Jagiellonian University Medical College (JUMC), American Children Hospital, neonatal Intensive Care Unit (ICU) due to abdominal distention, vomiting, and severe apneic episodes. With the preliminary diagnosis of the NB-HSCR-CCHS, the blood and tissue samples were acquired from the child, as well as from the child’s parents. All procedures were pursued in accordance with the Declaration of Helsinki, with the patient’s Guardian Informed Consent and the approval from the Institutional Review Board. Genetic/Genomic Methods Karyotyping was analyzed based upon Giemsa banding. The patient’s genomic DNA was extracted from peripheral blood and amplified by polymerase chain reaction. Direct microfluidic Sanger sequencing was performed on the genomic DNA amplicons. These procedures were pursued in addition to the routine clinical examinations and tests. Results G-banding showed the normal 46 XY karyotype. However, genomic sequencing revealed a novel, heterozygous deletion (8 nucleotides: c.699–706, del8) in exon 3 of the PHOX2B gene on chromosome 4. This led to the frame-shift mutation and malfunctioning gene expression product. Conclusion Herein, we report a novel PHOX2B gene mutation in the patient diagnosed with the NB-HSCR-CCHS cluster. The resulting gene expression product may be a contributor to the clinical manifestations of these genetic disorders. It adds to the library of the mutations linked to this syndrome. Consequently, we suggest that screening for the PHOX2B mutations becomes an integral part of genetic counseling, genomic sequencing of fetal circulating nucleic acids and / or genomes of circulating fetal cells prenatally, while preparing supportive therapy upon delivery, as well as on neonates' genomes of intubated infants, when breathing difficulties occur upon extubation. Further, we hypothesize that PHOX2B may be considered as a potential target for gene therapy. PMID:26798564

    The most common form of MS is relapsing remitting MS (RRMS). This is now a treatable condition and early diagnosis is becoming increasingly important in order to guide management decisions. After several years, RRMS may evolve into a slowly progressive deterioration in neurological function, known as secondary progressive MS. In 10-15% of people with MS, the condition follows this pattern of slow deterioration from onset, without relapses or remissions. This is primary progressive MS. It is difficult to predict prognosis in an individual patient. Factors associated with a favourable prognosis include female sex, onset with optic neuritis or sensory symptoms (rather than weakness or ataxia) and a long interval between initial relapses. RRMS is most commonly diagnosed in white women in their 20s. The first attack is known as a 'clinically isolated syndrome' reflecting inflammation in a single location. Common sites and symptoms are: optic nerve; spinal cord; sensory symptoms; Lhermitte's symptom and brainstem. The time course of symptoms is often helpful, as it is characteristic of inflammation. Patients tend to deteriorate over days, remain at a nadir for a week or two, and then recover over weeks. Recovery may be incomplete. Question patients directly to find out if there is a past history of any of the other common symptoms and perform a full neurological examination. Primary progressive MS should be suspected in patients presenting with a progressive spastic paraparesis or cerebellar syndrome. The diagnosis of MS should be made by a specialist and patients with a syndrome suggestive of MS should be referred to a neurologist. The mainstays of pharmacological treatment in RRMS are still the beta interferons and glatiramer acetate. These drugs reduce the rate of relapse by about a third and are therefore indicated for mobile patients with at least two relapses in the past two years. PMID:19873856

    Eagle syndrome, also known as elongated styloid process, is a condition first described by Watt Eagle in 1937. It occurs when an elongated styloid process or calcified stylohyoid ligament causes recurrent throat pain or foreign body sensation, dysphagia, or facial pain. Additional symptoms may include neck or throat pain with radiation to the ipsilateral ear. It is usually hard to diagnose because the symptoms related to this condition can be confused with those attributed to a wide variety of facial neuralgias. In this article, a case of Eagle syndrome exhibiting unilateral symptoms with bilateral elongation of styloid process is reported. PMID:24406612

    Fat embolism syndrome is an often overlooked cause of breathlessness in trauma wards. Presenting in a wide range of clinical signs of varying severity, fat embolism is usually diagnosed by a physician who keeps a high degree of suspicion. The clinical background, chronology of symptoms and corroborative laboratory findings are instrumental in a diagnosis of fat embolism syndrome. There are a few diagnostic criteria which are helpful in making a diagnosis of fat embolism syndrome. Management is mainly prevention of fat embolism syndrome, and organ supportive care. Except in fulminant fat embolism syndrome, the prognosis is usually good. PMID:23661916

  8. Neuroacanthocytosis Syndromes

    PubMed Central

    2011-01-01

    Neuroacanthocytosis (NA) syndromes are a group of genetically defined diseases characterized by the association of red blood cell acanthocytosis and progressive degeneration of the basal ganglia. NA syndromes are exceptionally rare with an estimated prevalence of less than 1 to 5 per 1'000'000 inhabitants for each disorder. The core NA syndromes include autosomal recessive chorea-acanthocytosis and X-linked McLeod syndrome which have a Huntingtons disease-like phenotype consisting of a choreatic movement disorder, psychiatric manifestations and cognitive decline, and additional multi-system features including myopathy and axonal neuropathy. In addition, cardiomyopathy may occur in McLeod syndrome. Acanthocytes are also found in a proportion of patients with autosomal dominant Huntington's disease-like 2, autosomal recessive pantothenate kinase-associated neurodegeneration and several inherited disorders of lipoprotein metabolism, namely abetalipoproteinemia (Bassen-Kornzweig syndrome) and hypobetalipoproteinemia leading to vitamin E malabsorption. The latter disorders are characterized by a peripheral neuropathy and sensory ataxia due to dorsal column degeneration, but movement disorders and cognitive impairment are not present. NA syndromes are caused by disease-specific genetic mutations. The mechanism by which these mutations cause neurodegeneration is not known. The association of the acanthocytic membrane abnormality with selective degeneration of the basal ganglia, however, suggests a common pathogenetic pathway. Laboratory tests include blood smears to detect acanthocytosis and determination of serum creatine kinase. Cerebral magnetic resonance imaging may demonstrate striatal atrophy. Kell and Kx blood group antigens are reduced or absent in McLeod syndrome. Western blot for chorein demonstrates absence of this protein in red blood cells of chorea-acanthocytosis patients. Specific genetic testing is possible in all NA syndromes. Differential diagnoses include Huntington disease and other causes of progressive hyperkinetic movement disorders. There are no curative therapies for NA syndromes. Regular cardiologic studies and avoidance of transfusion complications are mandatory in McLeod syndrome. The hyperkinetic movement disorder may be treated as in Huntington disease. Other symptoms including psychiatric manifestations should be managed in a symptom-oriented manner. NA syndromes have a relentlessly progressive course usually over two to three decades. PMID:22027213

    This study aims to explore a useful noninvasive assessment containing TCM syndrome elements for liver fibrosis in CHB patients. The demographic, clinical, and pathological data were retrospectively collected from 709 CHB patients who had ALT less than 2 times the upper limit of normal from April 2009 to October 2012. Logistical regression and area under receiver-operator curve (AUROC) were used to determine the diagnostic performances of simple tests for advanced fibrosis (Scheuer stage, F ? 3). Results showed that the most common TCM syndrome element observed in this CHB population was dampness and Qi stagnation, followed by blood stasis, by heat, and less by Qi deficiency and Yin deficiency. The logistical regression analysis identified AST ? 35 IU/L, PLT ? 161 109/L, and TCM syndrome element of blood stasis as the independent risk factors for advanced fibrosis. Therefore, a score model containing these three factors was established and tested. The score model containing blood stasis resulted in a higher AUC (AUC = 0.936) compared with APRI (AUC = 0.731) and FIB-4 (AUC = 0.709). The study suggested that the score model containing TCM syndrome element of blood stasis could be used as a useful diagnostic tool for advanced fibrosis in CHB patients and presented a better performance compared to APRI and FIB-4.

    Objective This study examines adolescent-specific practical problems associated with current practice parameters for diagnosing ADHD in order to inform recommendations for the diagnosis of ADHD in adolescents. Specifically, issues surrounding the use of self vs. informant ratings, diagnostic threshold, and retrospective reporting of childhood symptoms were addressed. Method Using data from the Pittsburgh ADHD Longitudinal Study (PALS), parent, teacher, and self-reports of symptoms and impairment were examined for 164 adolescents with a childhood diagnosis of ADHD (age M=14.74) and 119 demographically similar non-ADHD controls (total N=283). Results Results indicated that 70% of the well-diagnosed childhood ADHD group continued to meet DSM-IV-TR diagnostic criteria for ADHD in adolescence; however, an additional 17% possessed clinically significant impairment in adolescence, but did not qualify for a current ADHD diagnosis. The optimal source of information was combined reports from the parent and a core academic teacher. Adolescents with ADHD met criteria for very few symptoms of hyperactivity/impulsivity, suggesting a need to revisit the diagnostic threshold for these items. Additionally, emphasis on impairment, rather than symptom threshold improved identification of adolescents with a gold-standard childhood diagnosis of ADHD and persistent ADHD symptoms. Parent retrospective reports of baseline functioning, but not adolescent self-reports, were significantly correlated with reports collected at baseline in childhood. Conclusions We offer recommendations for diagnosing ADHD in adolescence based upon these findings. PMID:22148878

    2011-01-01

    Acute promyelocytic leukemia (APL) represents a medical emergency with a high rate of early mortality. As a consequence, as soon as the diagnosis is suspected based upon cytologic criteria, it is necessary to start all- trans retinoic acid (ATRA) treatment without delay. For patients with newly diagnosed APL, induction therapy with ATRA plus anthracycline based chemotherapy is recommended. At present the combination of arsenic trioxide plus ATRA should be considered for patients who are not candidates for anthracycline-based therapy. For pediatric and adult patients with APL aged < 60 years who achieve a CR with induction, I recommend 3 intensive courses of consolidation chemotherapy associated to ATRA, targeted on the basis of the risk group at diagnosis. In patients treated with a very intensive consolidation chemotherapy maintenance treatment can be omitted. However If a maintenance treatment has to be adopted I suggest the use of intermittent ATRA for 15 days every 3 months for a period of 2 years, rather than ATRA associated to chemotherapy. Moreover, taking into account the medical literature, a reduced dosage of ATRA ( 25 mg/m2) in pediatric patients and a consolidation chemotherapy of reduced intensity in elderly patients is recommended. Furthermore, in order to maximize survival, careful attention should be reserved to the coagulopathy and to the appearance of the differentiation syndrome. Finally, PCR for the PML/RARA fusion gene on a bone marrow specimen every three months for two years, and then every six months for additional three years are needed during the follow-up.

    Fraser's Syndrome (FS) is a rare autosomal recessive disorder with a spectrum of malformations. The most consistent features are Cryptophthalmos (CO), syndactyly, genitourinary tract abnormalities, laryngeal and tracheal anomalies, craniofacial dysmorphism, malformations of the ear and nose, orofacial clefting and musculoskeletal defects. FS is genetically heterogeneous; so far mutations in FRAS1, FREM2 and GRIP1 genes have been linked to FS. FS can be diagnosed on clinical examination, pre-natal ultrasound or perinatal autopsy. We present a case of a 3 months old child born to consanguineous healthy parents with bilateral complete CO, unilateral microphthalmia, hypertelorism, syndactyly (hands and feet bilaterally), ambiguous genitalia with cryptorchidism and an umbilical hernia. We also present the criteria for diagnosing FS and the significant features on pre-natal ultrasonography. Around 200 case reports of patients with FS and CO have been published. To our knowledge, this is the first reported case of FS in Pakistan. PMID:26522198

    Kartagener syndrome is a rare, ciliopathic, autosomal recessive genetic disorder that causes a defect in the action of the cilia lining the respiratory tract and fallopian tube. Patients usually present with chronic recurrent rhinosinusitis, otitis media, pneumonia, and bronchiectasis caused by pseudomonal infection. Situs inversus can be seen in about 50% of cases. Diagnosis can be made by tests to prove impaired cilia function, biopsy, and genetic studies. Treatment is supportive. In severe cases, the prognosis can be fatal if bilateral lung transplantation is delayed. We present a case of a 66-year-old woman with chronic recurrent upper respiratory infections, pseudomonal pneumonia, and chronic bronchiectasis who presented with acute respiratory failure. She was diagnosed with Kartagener syndrome based on her clinical presentation and genetic studies. She expired on ventilator with refractory respiratory and multiorgan failure. PMID:21403791

    The purpose of the present study was to determine the postnatal outcome and prognostic factors of prenatally diagnosed ventriculomegaly, and to establish the relationship between prenatal sonographic measurements and postnatal psychomotor development. A total of 42 singleton pregnancies with sonographically determined fetal ventriculomegaly at 20-38 weeks' gestation were reviewed, together with follow-up data on postnatal outcome at a mean of 29 months after delivery. Sonographic measurements included head circumference, cerebral lateral ventricular diameter at the anterior and posterior horn level, and hemisphere diameter. Classification of psycho-motor development consisted of assessment of motoric behaviour, speech, communication and social skills ('Van Wiechen' classification). Perinatal mortality rate was 38 per cent, of which half were directly associated with cephalocentesis. Only the ventricle/hemisphere ratio for the anterior and posterior horn of the lateral cerebral ventricles was significantly higher among perinatal deaths than amongst the survivors. Within the subset of survivors (n = 26), psycho-motor development was normal in 46 per cent. Postnatal examination revealed syndrome anomalies in five infants, of which four were associated with psycho-motor retardation. Prenatally diagnosed ventriculomegaly has a poor postnatal outcome with more than 50 per cent of the live-born infants demonstrating abnormal psycho-motor development. The predictive value of fetal biometric measurements is poor. The presence of syndromal anomalies emphasizes the need for genetic counselling in future pregnancies. PMID:9664600

    Antiphospholipid syndrome is diagnosed when arterial or venous thrombosis or recurrent miscarriages occur in a person in whom laboratory tests for antiphospholipid antibodies (anticardiolipin antibodies and/or lupus anticoagulant and/or anti-beta 2-glycoprotein I) are positive. Despite the strong association between antiphospho-lipid antibodies and thrombosis, their pathogenic role in the development of thrombosis has not been fully elucidated. Novel mechanisms involving both the complement pathway and micro-particles have been described. The knowledge of these new pathogenic approaches might identify novel therapeutic targets and therefore may improve the management of these patients. PMID:19090981

    Cardio-facio-cutaneous (CFC) syndrome is characterized by a variable degree of developmental delay and congenital anomalies, including characteristic facial, cardiac, and ectodermal abnormalities. It is caused by activating mutations in the Ras/mitogen-activated protein kinase (MAPK) signaling pathway. In, however, approximately 10%-30% of individuals with a clinical diagnosis of CFCS, no mutation of the causative gene is found. Therefore, clinical studies in patients with the CFCS spectrum are valuable. To investigate the phenotypic spectrum and molecular diversity of germline mutations affecting genes encoding serine/threonine kinases, a group of 15 children and young adults with a diagnosis of CFCS was screened. We documented three novel mutations in the BRAF gene and correlated clinical findings with causative mutations in the BRAF or MEK1/MEK2 genes. PMID:25463315

    Of the 3574 malignant melanomas treated in Hornheide between December 1981 and August 1990 (not including preinvasive cases) 97 were not immediately recognized. These tumours did not look like melanomas. In 72% they were smaller than 10 mm in diameter, and in 20%, smaller than 5 mm. Clark's so often quoted "pencil rule" should no longer be used as an aid to exclusion of invasive melanoma. Localization of the unrecognized melanomas was on the head and neck in 22% of cases. In 37%, the patients were under the age of 40 years. No less than 25% of the patients had multiple melanomas. Many of these melanomas. Many of these melanomas were thin tumours (less than 0.75 mm in 55% and less than 1.5 mm in 77%). This explains why more than 50% of the lesions are described as "macules". The most common incorrect diagnoses were dysplastic naevi (44%) and common (23%) naevi. The most important anamnestic criteria are the patients' own statements about changes in size, colour and shape. These "dynamic" elements must be more carefully observed and documented during process of the clinical diagnosis. PMID:1860796

    Acanthamoeba keratitis is rare corneal disease, its etiology is caused by amoebae of the Acanthamoeba spp. In this paper, the newest findings about the diagnostic and treatment procedures of the disease and epidemiology and preventive issues from the point of public health are presented. The article presents results of the water quality monitoring (according to the Acanthamoeba which is possible to cultivate at 36 degrees C and 44 degrees C) in man-made swimming pools during the period 2004-2008 at the Department of environmental biology of the Regional Public Health Institute in Banská Bystrica, Slovakia, E.U. The examination methods present the techniques of the clinical sampling and taking samples from the environment. The results underline the use of the new effective criteria in controlling of recreational resorts as well as changes of the legal criteria for the water quality used by the public. The results show that the presence of Acanthamoeba spp. in the environment is common, so the water monitoring is perceived as substantial preventive issue to prevent the disease to emerge. The collaboration between the public heath departments and ophthalmologists during the examination of the clinical and environmental samples may help to prevent and diagnose the Acanthamoeba keratitis.

    The psychiatric community seems determined to ground its medical legitimacy on principles that confuse diagnoses with disease. If mental illnesses are diseases of the CNS, they are diseases of the brain, not the mind. If mental illnesses are the names of (mis)behaviour, they are forms of behaviour, not diseases. Psychiatric metaphors have the same role in medicine as religious metaphors have in theology. Religion is, among other things, the institutionalised denial of a finite life. Psychiatry is, among other things, the institutionalised denial of the tragic nature of life: individuals who want to reject the reality of free will and responsibility can medicalise life, and entrust its management to health professionals. Psychiatrists have succeeded in persuading the scientific community, the courts, the media, and the general public that the conditions they call mental disorders are diseases, that is, phenomena independent of motivation or will. The more firmly psychiatrically based ideas take hold of the collective American mind, the more foolishness and injustice they generate. Long ago, the law makers agreed to let psychiatrists literalise the metaphor of mental illnesses. Thus, the Americans With Disabilities Act (AWDA), scheduled to be fully implemented by July 1992, covers claustrophobia, personality problems, and mental retardation, though unlike DSM-III-R it excludes kleptomania, pyromania, compulsive gambling, and transvestism. The literal language of psychiatry allows motivated actions to be called 'disease'. Other examples of behaviour for which psychiatrists have disease names, and which AWDA implicitly accepts as genuine diseases, include dysmorphophobia, multiple personality disorder, frotteurism, hypoactive sexual desire disorder, and fractitious disorder with physical symptoms.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1422620

    A 19-year-old sportsman experienced a right-sided pneumothorax and hemoptysis after having had an intermittent cough and blood-tinged sputum for 2 months. A chest CT scan revealed small cavitary lesions in both lungs. The relapsing pneumothorax was treated with a chest tube twice, as well as surgically after the second relapse. Two months after surgery, the patient developed a cough, fever, and high C-reactive protein levels. At that time, large consolidations had developed in the right lung, while the left lung subsequently collapsed due to pneumothorax. The patient's physical appearance and anamnestic information led us to suspect a genetic connective tissue disease. A sequencing analysis of the COL3A1 gene identified a novel, de novo missense mutation that confirmed the diagnosis of vascular Ehlers-Danlos syndrome (EDS). This atypical presentation of vascular EDS with intrathoracic complications shows that enhanced awareness is required and demonstrates the usefulness of the genetic analyses that are clinically available for several hereditary connective tissue disorders.

    The authors present the history of selecting and understanding the essence of the metabolic syndrome (X syndrome, Reaven's syndrome) related to insulin resistance as well as its contemporary working definition allowing diagnosing affected individuals. They describe the cycle of their own study investigating the prevalence of metabolic syndrome elements in patients treated because of their thyrotoxicosis. It has been observed that 4 weeks after thyrostatic treatment is started, many of these patients are affected by the growth of their body mass and total cholesterol level (mostly at the cost of LDL-cholesterol). After 2 years the growth of body mass is significant, many patients develop arterial hypertension. After 15 years of obesity, diabetes type 2 (DM-2), arterial hypertension, dyslipidemia, hyperinsulinaemia and full metabolic syndrome are found much more frequently than in the control group. In the research carried in the 1987--1989 period, we found the following in 11,546 subjects from the Lublin region (villagers aged over 18): overweight in 36% women and 34% of men, and obesity in 30% of women and 10% of men, and arterial hypertension in 24.2% and DM 2 in 2.7% of the whole examined group. Within the research carried out between 1998 and 2000 we examined 3,782 persons (63%) out of 6,000 persons aged over 35 carefully selected from the Lublin town and the Lublin region villages. DM 2 was found in 17.6% of the examined in the countryside and in 14.1% from the town (newly diagnosed diabetes--75% and 56% respectively). Obesity (BMI > or = 30 kg/m2) was found in 30.8% of the examined from villages and 30.1% town dwellers, arterial hypertension (RR > or = 140/90 mmHg) was found in 69.4% villagers and 68.6% subjects from the town. Total serum cholesterol > or = 5.2 mmol/l (200 mg/dl) was found in 66.4% of the examined from the countryside and in 60% from the town, LDL-cholesterol > or = 3.5 mmol/l (135 mg/dl) was found in 57.3% and 52.6% respectively, and triglycerides > or = 1.7 mmol/l (150 mg/dl) in 33,3% and 44.8 respectively. Hypo-HDL-cholesterolaemia was found in 21.7% of the examined from villages and in 31.4% of the examined from Lublin. 76.5% of the examined from the countryside and 72.7% from the town had a raised WHR index.

    2007-01-01

    First introduced as a new clinical entity in 1992, the Brugada syndrome is associated with a relatively high risk of sudden death in young adults, and occasionally in children and infants. Recent years have witnessed a striking proliferation of papers dealing with the clinical and basic aspects of the disease. Characterized by a coved-type ST-segment elevation in the right precordial leads of the electrocardiogram (ECG), the Brugada syndrome has a genetic basis that thus far has been linked only to mutations in SCN5A, the gene that encodes the ?-subunit of the sodium channel. The Brugada ECG is often concealed, but can be unmasked or modulated by a number of drugs and pathophysiological states including sodium channel blockers, a febrile state, vagotonic agents, tricyclic antidepressants, as well as cocaine and propranolol intoxication. Average age at the time of initial diagnosis or sudden death is 40 22, with the youngest patient diagnosed at 2 days of age and the oldest at 84 years. This review provides an overview of the clinical, genetic, molecular, and cellular aspects of the Brugada syndrome, incorporating the results of two recent consensus conferences. Controversies with regard to risk stratification and newly proposed pharmacologic strategies are discussed. PMID:17038146

    The gastroesophageal reflux (GER) disease is a very frequent digestive disorder, mainly characterised by the reflux of the gastric acidic content to the esophage in abnormal quantities. There are different situations that favour this situation but almost in all of them rely an incompetence of the esophagic sphincter. The clinical consequences are many, including oral manifestations. Among all of them the most frequent is the esophagitis followed by symptoms at the pharynx or larynx and finally, the oral cavity. At this level fundamentally we will find enamel and oral mucosa erosions. We report the case of a patient who was indirectly diagnosed of her esophague disease by the observation of the alterations in the occlusal splint induced by the gastric reflux. We review the literature concerning the above topic and its possible association with the miofascial syndrome. PMID:16388289

    Introduction Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) is characterized by features other than increased pulmonary vascular permeability. Pulmonary vascular permeability combined with increased extravascular lung water content has been considered a quantitative diagnostic criterion of ALI/ARDS. This prospective, multi-institutional, observational study aimed to clarify the clinical pathophysiological features of ALI/ARDS and establish its quantitative diagnostic criteria. Methods The extravascular lung water index (EVLWI) and the pulmonary vascular permeability index (PVPI) were measured using the transpulmonary thermodilution method in 266 patients with PaO2/FiO2 ratio ? 300 mmHg and bilateral infiltration on chest radiography, in 23 ICUs of academic tertiary referral hospitals. Pulmonary edema was defined as EVLWI ? 10 ml/kg. Three experts retrospectively determined the pathophysiological features of respiratory insufficiency by considering the patients' history, clinical presentation, chest computed tomography and radiography, echocardiography, EVLWI and brain natriuretic peptide level, and the time course of all preceding findings under systemic and respiratory therapy. Results Patients were divided into the following three categories on the basis of the pathophysiological diagnostic differentiation of respiratory insufficiency: ALI/ARDS, cardiogenic edema, and pleural effusion with atelectasis, which were noted in 207 patients, 26 patients, and 33 patients, respectively. EVLWI was greater in ALI/ARDS and cardiogenic edema patients than in patients with pleural effusion with atelectasis (18.5 6.8, 14.4 4.0, and 8.3 2.1, respectively; P < 0.01). PVPI was higher in ALI/ARDS patients than in cardiogenic edema or pleural effusion with atelectasis patients (3.2 1.4, 2.0 0.8, and 1.6 0.5; P < 0.01). In ALI/ARDS patients, EVLWI increased with increasing pulmonary vascular permeability (r = 0.729, P < 0.01) and was weakly correlated with intrathoracic blood volume (r = 0.236, P < 0.01). EVLWI was weakly correlated with the PaO2/FiO2 ratio in the ALI/ARDS and cardiogenic edema patients. A PVPI value of 2.6 to 2.85 provided a definitive diagnosis of ALI/ARDS (specificity, 0.90 to 0.95), and a value < 1.7 ruled out an ALI/ARDS diagnosis (specificity, 0.95). Conclusion PVPI may be a useful quantitative diagnostic tool for ARDS in patients with hypoxemic respiratory failure and radiographic infiltrates.

    Background Although the epidemic of metabolic syndrome (MetS) has aroused wide public concern, most studies on MetS tend to examine urban and high income settings, and few studies cover nomadic areas and low earning populations. This research aims to investigate the prevalence of MetS and explore the cut-off point of waist circumference in a nomadic minority typical of low income populations in the remote northwest region of China. Methods A cross-sectional study was performed in a representative sample of 3900 Kazakh adults aged 18–84 years from 2009–2010. Three widely used criteria (ATP III\\IDF\\JIS) were employed to estimate the prevalence of MetS in Kazakhs to compare them with other populations. Receiver operator characteristic (ROC) curve analysis was used to explore the optimal cut-off values of waist circumference. Results The age-adjusted prevalence of MetS was 13.8%, 20.9%, and 24.8% based on the ATP III, IDF, and JIS criteria, respectively. The prevalence of MetS was higher in women and increased with age. Except for reduced HDL-cholesterol, the risk of other components of MetS increased with waist circumference enlargement. The cut-off point of waist circumference in screening at least two other components of MetS was 88 cm in men (Sensitivity = 61.1%, Specificity = 62.1%, ROC Curve Distance = 0.54) and 83 cm in women (Sensitivity = 60.0%, Specificity = 59.6%, ROC Curve Distance = 0.57). Conclusion The prevalence of MetS in Kazakhs is higher than the national level of China and falls in between the Euro-American and Asia levels, as their cut-off points of waist circumference differ from that recommended for Chinese. We suggest a cost-effective strategy to screen for MetS and prevent cardiovascular disease using new cut-off points of waist circumference in low earning nomadic Kazakhs. PMID:26901035

    2012-06-01

    This review presents criteria for diagnosing the "syndrome of dementia" based on the S3 guidelines of the AWMF ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften") in Germany. They represent the best standards of evidence-based international knowledge, in light of the National Institute for Health and Clinical Excellent (NICE), the Scottish Intercollegiate Guidelines Network (SIGN), etc. Diagnosing dementia as early as possible is essential. All the current guidelines specify a two-step procedure: the first step entails performing a comprehensive diagnosis of the syndrome, while the second step involves diagnosing the precise etiology. The following article focuses on the first step: diagnosis of the syndrome. PMID:22622679

  6. Diagnosing autism spectrum disorders in primary care.

    PubMed

    Allely, Clare S; Wilson, Philip

    2011-11-01

    Autism is a disorder of social communication, originally described as a triad of impaired social interaction, communication, and imagination, associated with a rigid, repetitive pattern of behaviour. More recently the core deficit has been described as a lack of social instinct. The term autism spectrum disorder (ASD) includes autism, atypical autism and Asperger's syndrome. According to NICE, diagnostic assessment should start within three months of referral. The decision to refer should be made on the basis of signs or symptoms. Information from all sources (i.e. medical history, parental concerns, clinical judgement) should be used to diagnose ASD based on ICD-10 or DSM-IV criteria. Clinicians should not rely on any one autism-specific diagnostic tool alone to diagnose ASD. Diagnosis is based primarily on the recognition and interpretation of behavioural symptoms. CHAT or the modified version (M-CHAT) are simple checklists that can be used for the assessment of young children in primary care when ASD is suspected. They can identify clinical features indicative of increased risk but should not be used to rule out ASD. PMID:22235552

    Mitochondrial disorders (MIDs) require biochemical or genetic investigations for being diagnosed. In some cases, however, the diagnosis can be suspected upon the syndromic phenotype or upon clinical presentation and family history, as in the following case. The patient was a 74-year-old male admitted for worsening of pre-existing left-sided ptosis and ophthalmoparesis after a birthday party. The history was positive for arterial hypertension, hypertrophic cardiomyopathy with systolic dysfunction, diabetes-type 2, mild renal insufficiency, thyroiditis, and polyneuropathy. Instrumental investigations additionally revealed hepatopathy, hyperlipidemia, hyperuricemia, bifascicular block, white matter lesions, and subacute stroke. Systolic dysfunction resolved upon adequate cardiac treatment. On hospital day 11 the patient suddenly developed asystole. He was successfully resuscitated but died a few hours later from acute myocardial infarction. Surprisingly, a more extensive family history was positive for myopathy (patient, brother, daughter), neuropathy (patient), hypoacusis (patient), Parkinson syndrome (mother), spasticity (son), diabetes (patient, son), renal failure (patient), and generalized atherosclerosis (patient). The individual and family history was strongly suggestive of an MID. In conclusion, individual and family history may strongly suggest MID. Phenotypic variability may be high between family members affected by an MID. MID may be associated with an increasing atherosclerotic risk lastly resulting in coronary heart disease and death.

    2004-01-01

    Adrenalectomy is a radical therapeutic approach to control hypercortisolism in some patients with Cushing's disease. However it may be complicated by the Nelson's syndrome, defined by the association of a pituitary macroadenoma and high ACTH secretion after adrenalectomy. This definition has not changed since the end of the fifties. Today the Nelson's syndrome must be revisited with new to criteria using more sensitive diagnostic tools, especially the pituitary magnetic resonance imaging. In this paper we will review the pathophysiological aspects of corticotroph tumor growth, with reference to the impact of adrenalectomy. The main epidemiological data on the Nelson's syndrome will be presented. More importantly, we will propose a new pathophysiological and practical approach to this question which attempts to evaluate the Corticotroph Tumor Progression after adrenalectomy, rather than to diagnose the Nelson's syndrome. We will discuss the consequences for the management of Cushing's disease patients after adrenalectomy, and will also draw some perspectives. PMID:16132203

    This case report is about an elderly man who presented with a long-standing history of high-grade fever and weight loss. He initially had only hepatosplenomegaly, but then developed jaundice. He also had pancytopenia and raised liver enzymes. His septic screen was negative, but he had a positive Monospot test and immunoglobulin G for Epstein-Barr virus. The liver biopsy showed sinusoidal phagocytosis and the subsequent bone marrow aspiration and biopsy showed significant hemophagocytosis, hence Hemophagocytic syndrome was diagnosed. The fever was refractory to antibiotic and anti-tuberculosis therapy, but it responded only partially to steroids. Full response was only noticed following anti-viral treatment in the form of intravenous Ganciclovir. The patient's general condition, liver enzymes, bilirubin, hematological parameters and even the weight returned back to their normal range 2 weeks after Ganciclovir therapy. Cessation of this drug resulted in relapse of his symptoms and oral antivirals did not help. Splenectomy, steroid pulse therapy and immunosuppressive treatment were only partially helpful. Reintroduction of Ganciclovir did help for a short period. We conclude that our patient had virus-associated hemophagocytic syndrome most likely related to Epstein-Barr virus infection, which was then confirmed by the splenic biopsy, and that Ganciclovir can be of great help in eradicating the virus and treating the disease, provided that it is given for a long enough period.

    Background This study aimed to examine the associations between psychiatric diagnoses, trauma and suicidiality in psychiatric patients at intake. Methods During two months, all consecutive patients (n = 139) in a psychiatric hospital in Western Norway were interviewed (response rate 72%). Results Ninety-one percent had been exposed to at least one trauma; 69 percent had been repeatedly exposed to trauma for longer periods of time. Only 7% acquired a PTSD diagnosis. The comorbidity of PTSD and other psychiatric diagnoses were 78%. A number of diagnoses were associated with specific traumas. Sixty-seven percent of the patients reported suicidal thoughts in the month prior to intake; thirty-one percent had attempted suicide in the preceding week. Suicidal ideation, self-harming behaviour, and suicide attempts were associated with specific traumas. Conclusion Traumatised patients appear to be under- or misdiagnosed which could have an impact on the efficiency of treatment. PMID:17448229

    Increased tissue pressure within a fascial compartment may be the result from any increase in volume within its contents, or any decrease in size of the fascial covering or its distensibility. This may lead to symptoms of leg tightness, pain or numbness brought about by exercise. There are multiple differential diagnoses of exercise induced leg pain and the proper diagnoses of chronic exertional compartment syndrome (CECS) is made by a careful history and by exclusion of other maladies and confirmed by compartment syndrome testing as detailed in this text. Surgical fasciotomies for the anterior, lateral, superficial and deep posterior compartments are described in detail along with ancillary procedures for chronic shin splints that should allow the athlete to return to competitive activity.

    Background Neuroferritinopathy (NF) is a rare autosomal dominant disease caused by mutations in the ferritin light chain 1 (FTL1) gene leading to abnormal excessive iron accumulation in the brain, predominantly in the basal ganglia. Methods A literature search was performed on Pubmed, for English-language articles, utilizing the terms iron metabolism, neurodegeneration with brain iron accumulation, and NF. The relevant articles were reviewed with a focus on the pathophysiology, clinical presentation, differential diagnoses, and management of NF. Results There have been nine reported mutations worldwide in the FTL1 gene in 90 patients, the most common mutation being 460InsA. Chorea and dystonia are the most common presenting symptoms in NF. There are specific features, which appear to depend upon the genetic mutation. We discuss the occurrence of specific mutations in various regions along with their associated presenting phenomenology. We have compared and contrasted the commonly occurring syndromes in the differential diagnosis of NF to guide the clinician. Discussion NF must be considered in patients presenting clinically as a progressive movement disorder with variable phenotype and imaging evidence of iron deposition within the brain, decreased serum ferritin, and negative genetic testing for other more common movement disorders such as Huntington’s disease. In the absence of a disease-specific treatment, symptomatic drug therapy for specific movement disorders may be used, although with variable success.

    Brugada syndrome is increasingly recognized as a cause of sudden cardiac death. Many of these patients do not get diagnosed due its dynamic and often hidden nature. We have come a long way in understanding the disease process, and its electrophysiology appears to be intimately linked with sodium channel mutations or disorders. The cardiac rhythm in these patients can deteriorate into fatal ventricular arrhythmias. This makes it important for the clinician to be aware of the conditions in which arrhythmogenicity of Brugada syndrome is revealed or even potentiated. We present such an instance where our patient’s Brugada syndrome was unmasked by fever. PMID:26425637

Perinatal outcomes were compared in non-isolated (n=23) and isolated omphaloceles (n=23). Results For all omphaloceles, the majority delivered after 34 weeks by cesarean. Mean birth weight (2782 vs. 2704g), median length of stay (27 vs. 25 days), and mortality (2 in each group) was not different between the non-isolated and isolated groups, P>0.05. In the non-isolated group, 7 major anomalies were not confirmed postnatally. Of the prenatally diagnosed isolated omphaloceles, 8(35%) were diagnosed with a syndrome or other anomalies after birth. Conclusion The outcomes were similar in non-isolated and isolated prenatally diagnosed omphaloceles, but ultrasound did not always accurately determine the presence or absence of associated anomalies.

    Gorlin-Goltz syndrome or basal cell nevus syndrome is a comparatively rare syndrome characterized by basal cell nevi, odontogenic keratocysts, and skeletal anomalies. Diagnosis is based on the major and minor clinical and radiographic criteria. Dentist plays a major role in the diagnosis of this disease due to the oral and maxillofacial manifestations of the syndrome. In some cases, jaw cysts are diagnosed by routine radiographs advised by the dentists. Odontogenic keratocysts in such syndromic patients will be multiple and extensive and in some cases results in cortical expansion and facial disfigurement. Thorough clinical examination and investigations prompt an early confirmation of the syndrome, which is very essential to avoid morbidity associated with the syndrome. Here, we report a case of multiple odontogenic cysts in a 16-year-old patient which later was diagnosed as a case of Gorlin Goltz syndrome. PMID:25821359

Due to the positional nature of the headache and its frontal and occipital origin, a postdural puncture headache was diagnosed. After failure of conservative treatment, an epidural blood patch was used, which offered immediate relief. However, shortly following the procedure, the parturient's neurological condition deteriorated due to an unrecognized intraparenchymal and subarachnoid hemorrhage requiring an emergent craniectomy.

    A case is reported where the major clinical features of craniostenosis and radial aplasia led to an initial diagnosis of Baller-Gerold syndrome. Mild fibular hypoplasia on skeletal survey led to review of the diagnosis and the similarity of the facial phenotype to that of Roberts syndrome was noted. Chromosome analysis showed the premature centromere separation characteristic of this condition. This case raises the question as to whether the Baller-Gerold syndrome can be considered as a distinct entity. It is suggested that cases diagnosed as having Baller-Gerold syndrome should have cytogenetic analysis and that known Roberts syndrome survivors are reviewed for signs of craniostenosis.

    Objective Dementia is a common clinical presentation among older adults with Down syndrome. The presentation of dementia in Down syndrome differs compared with typical Alzheimers disease. The performance of manualised dementia criteria in the International Classification of Diseases (ICD)-10 and Diagnostic and Statistical Manual of Mental Disorders-IV-Text Revision (DSM-IV-TR) is uncertain in this population. We aimed to determine the concurrent validity and reliability of clinicians diagnoses of dementia against ICD-10 and DSM-IV-TR diagnoses. Validity of clinical diagnoses were also explored by establishing the stability of diagnoses over time. Methods We used clinical data from memory assessments of 85 people with Down syndrome, of whom 64 (75.3%) had a diagnosis of dementia. The cases of dementia were presented to expert raters who rated the case as dementia or no dementia using ICD-10 and DSM-IV-TR criteria and their own clinical judgement. Results We found that clinicians judgement corresponded best with clinically diagnosed cases of dementia, identifying 84.4% cases of clinically diagnosed dementia at the time of diagnosis. ICD-10 criteria identified 70.3% cases, and DSM-IV-TR criteria identified 56.3% cases at the time of clinically diagnosed dementia. Over time, the proportion of cases meeting ICD-10 or DSM-IV-TR diagnoses increased, suggesting that experienced clinicians used their clinical knowledge of dementia presentation in Down syndrome to diagnose the disorder at an earlier stage than would have been possible had they relied on the classic description contained in the diagnostic systems. Conclusions Clinical diagnosis of dementia in Down syndrome is valid and reliable and can be used as the standard against which new criteria such as the DSM-5 are measured. PMID:25363568

    Purpose of Review The different parkinsonian conditions can be challenging to separate clinically. This review highlights the important clinical features that guide the diagnosis of Parkinson disease (PD), progressive supranuclear palsy (PSP), multiple system atrophy (MSA), and corticobasal degeneration (CBD). Strategies for treatment and disease management are also discussed. Recent Findings Over the past decade there has been an increasing recognition of the broad clinical presentations of the neurodegenerative forms of parkinsonism. Nonmotor symptoms in these diseases, including psychiatric, cognitive, autonomic, and gastrointestinal dysfunction, appear to have a major impact on quality of life and disability. PSP and CBD are now considered pathologic diagnoses, with several different and varied clinical phenotypes, that overlap and share features with PDand frontotemporal dementia syndromes. PD is distinguished by its excellent response to dopaminergic medications that is maintained over many years, in contrast to the response seen in patients with MSA and PSP. New diagnostic criteria have been proposed for CBD. No new therapeutic interventions have emerged for PSP, MSA, or CBD. Infusional therapies and deep brain stimulation surgery are established therapies for advanced PD. Summary The “parkinsonian syndromes” encompass a number of nosologic entities that are grouped together on the basis of their shared clinical features but are separated on the basis of their different pathologies. Overall, the consideration of clinical signs, mode of disease onset, and nature of disease progression are all important to make a timely and definitive diagnosis. PMID:24092286

    HELLP syndrome belongs to the group of pathological disorders associated with pregnancy-induced hypertension and may accompany preeclampsia. The basic criteria for establishing the diagnosis are as follows: H--for hemolysis, EL--for elevated liver enzymes and LP--for low platelets. In this report the authors present the case of a 32 years old primipara admitted to the Obstetrics Clinic complaining of epigastric pain, nausea and vomiting. Medical history revealed previously diagnosed and treated reflux disease. In the 39th week of gestation epigastric pain manifested again, blood pressure was high (150/100) and on the basis of laboratory parameters HELLP syndrome was diagnosed (GPT 319 U/L, GOT 204 U/L, platelet 80 x 10(9)/L, antithrombin III 63.9%, D-dimer (+++)).

    Moyamoya-like vasculopathy develops in association with various systemic diseases and conditions, which is termed moyamoya syndrome. Relatively common diseases and conditions are related to moyamoya syndrome, including neurofibromatosis type 1, Down syndrome, thyroid disease, and cranial irradiation. Moyamoya syndrome shares phenotypical characteristics with idiopathic moyamoya disease. However, they differ in other details, including clinical presentations, natural history, and treatment considerations. The study of moyamoya syndrome can provide clinicians and researchers with valuable knowledge and insight. Although it is infrequently encountered in clinical practice, moyamoya-like vasculopathy can severely complicate outcomes for patients with various underlying diseases when the clinician fails to expect or diagnose moyamoya syndrome development. Furthermore, moyamoya syndrome could be used as a doorway to more enigmatic moyamoya disease in research. More comprehensive survey and investigation are required to uncover the secrets of all the moyamoya-like phenomena. PMID:26180607

    2013-01-01

    Background In spite of the role of some psychosomatic factors as alexithymia, mood intolerance, and somatization in both pathogenesis and maintenance of anorexia nervosa (AN), few studies have investigated the prevalence of psychosomatic syndromes in AN. The aim of this study was to use the Diagnostic Criteria for Psychosomatic Research (DCPR) to assess psychosomatic syndromes in AN and to evaluate if psychosomatic syndromes could identify subgroups of AN patients. Methods 108 AN inpatients (76 AN restricting subtype, AN-R, and 32 AN binge-purging subtype, AN-BP) were consecutively recruited and psychosomatic syndromes were diagnosed with the Structured Interview for DCPR. Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory2, and Temperament and Character Inventory. Data were submitted to cluster analysis. Results Illness denial (63%) and alexithymia (54.6%) resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%), somatization group (26%), and severe psychosomatic group (25%). The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome. Conclusions These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments. PMID:23302180

    Objective Diagnoses using imaging-based measures alone offer the hope of improving the accuracy of clinical diagnosis, thereby reducing the costs associated with incorrect treatments. Previous attempts to use brain imaging for diagnosis, however, have had only limited success in diagnosing patients who are independent of the samples used to derive the diagnostic algorithms. We aimed to develop a classification algorithm that can accurately diagnose chronic, well-characterized neuropsychiatric illness in single individuals, given the availability of sufficiently precise delineations of brain regions across several neural systems in anatomical MR images of the brain. Methods We have developed an automated method to diagnose individuals as having one of various neuropsychiatric illnesses using only anatomical MRI scans. The method employs a semi-supervised learning algorithm that discovers natural groupings of brains based on the spatial patterns of variation in the morphology of the cerebral cortex and other brain regions. We used split-half and leave-one-out cross-validation analyses in large MRI datasets to assess the reproducibility and diagnostic accuracy of those groupings. Results In MRI datasets from persons with Attention-Deficit/Hyperactivity Disorder, Schizophrenia, Tourette Syndrome, Bipolar Disorder, or persons at high or low familial risk for Major Depressive Disorder, our method discriminated with high specificity and nearly perfect sensitivity the brains of persons who had one specific neuropsychiatric disorder from the brains of healthy participants and the brains of persons who had a different neuropsychiatric disorder. Conclusions Although the classification algorithm presupposes the availability of precisely delineated brain regions, our findings suggest that patterns of morphological variation across brain surfaces, extracted from MRI scans alone, can successfully diagnose the presence of chronic neuropsychiatric disorders. Extensions of these methods are likely to provide biomarkers that will aid in identifying biological subtypes of those disorders, predicting disease course, and individualizing treatments for a wide range of neuropsychiatric illnesses.

    Since 1966, the Hawaii State Government has been conducting Fluorescent Rabies Antibody (FRA) testing on animal brains as part of a statewide rabies-surveillance program. On April 3, 1991, the Department of Health (DoH) laboratory diagnosed the first case of rabies detected in the State. A large brown bat, Eptesicus fuscus fuscus, captured in a transport container that had just been off-loaded from a ship at Honolulu harbor, was caught. It's brain was examined and showed typical fluorescent staining patterns for rabies virus. The USPHS Centers For Disease Control (CDC) rabies laboratory confirmed the diagnosis 2 days later. The successful interception of this rabid animal was the result of close cooperation between the private sector (Sea Land Service, Hawaiian Stevedores) and the Hawaii State Government Departments of Health and of Agriculture.

    POEMS syndrome is a rare multisystem disorder, characterized by the presence of polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin changes. The variety of clinical pictures and asynchronous manifestation of dominant features make diagnosis difficult. We report a case of a 42-year-old man with polyneuropathy who was initially negative for monoclonal protein and so Guillain-Barr syndrome was diagnosed. Other signs and symptoms, including monoclonal gammopathy, developed later in the course of the disease and finally POEMS syndrome was diagnosed. PMID:22773516

    Congenital structural cardiovascular defects are commonly associated and found concurrently with many different types of genetic diseases and syndromes. Understanding these cardiovascular manifestations is essential for diagnosing these genetic syndromes without delay and provides prompt attention and repair of life-threatening defects without complications. Computed tomography and magnetic resonance imaging are increasingly used in the evaluation of cardiovascular abnormalities, and it is imperative for radiologists to be cognizant of the syndromes associated with these abnormalities. In this article, we review the cardiovascular manifestations of the common genetic syndromes and illustrate the role of computed tomography and magnetic resonance imaging in the evaluation of these abnormalities.

    PURPOSE: To screen severe to profound, preverbal hearing-impaired children for Usher syndrome by ophthalmologic examinations, including electroretinographic testing. These patients are especially good candidates for early cochlear implants, which will improve listening and spoken language skills. METHODS: Consecutive patients over 2 years of age, given a diagnosis of severe to profound, preverbal hearing loss, were screened for Usher syndrome by a complete ophthalmologic examination including an electroretinogram. RESULTS: Five of 48 patients screened (10.4%) were diagnosed with Usher syndrome and received cochlear implants. CONCLUSION: All children with severe to profound, preverbal sensorineural hearing loss should be screened for Usher syndrome by ophthalmologic examination including electroretinogram. PMID:11190026

    Although tics are considered the hallmark of Tourette syndrome, arguably tics may not be the only or primary presenting symptom. For many children diagnosed with Tourette syndrome irritability, frustration intolerance, hyperactivity, inattention, ritual behavior or other difficulties may have been present a number of years before the appearance of tics. Children with Tourette syndrome are often highly co-morbid with attention deficit-hyperactivity disorder, obsessive compulsive symptoms, and other related behavioral problems that should be detected and treated effectively. Therefore tics should not be the sole indicator or receive over emphasis in the detection and treatment of Tourette syndrome. PMID:16265842

    Triple-A syndrome is characterized by triad of adrenocorticotrophic hormone (ACTH)-resistant adrenal insufficiency, alacrimia and achalasia cardia. It is a rare disease and inherited by autosomal recessive pattern. Allgrove syndrome is characterized by mutation(s) in AAAS gene, located on chromosome 12q13, that codes for ALADIN protein. Most mutations produce a truncated protein, although missense and point-mutations have also been reported. Some patients with Triple-A syndrome may not have mutations in AAAS gene; in those there is no specific genotype-phenotype correlation. Although alacrimia is not the usual presenting manifestation, probably it is the earliest and most consistent feature. Achalasia cardia and adrenal insufficiency are the early and usual presenting manifestations. Neurological features appear at later age and autonomic manifestations are the most common neurological disorder. Polyneuropathy, amyotrophy, optic atrophy are the other common neurological problems. Alacrimia is diagnosed by Schirmer's test while ahalasia cardia and adrenal insufficiency are best diagnosed by esophageal monometry and ACTH stimulated cortisol levels respectively. Alacrimia is treated with artificial tears while achalasia cardia with either pneumatic dilatation or Heller's myotomy. Adrenal insufficiency is treated with glucocorticoid and if necessary mineralocorticoid replacement. PMID:20687490

    To date, there have been a very limited number of case reports on combined Alport syndrome (AS) and Klinefelter syndrome (KS). We herein describe the case of a 9-month-old boy diagnosed with concomitant AS and KS. KS was detected on chromosomal analysis of the amniotic fluid, and hematuria/proteinuria was identified in urinary screening at 6?months of age. Renal biopsy indicated AS, with complete deficit of the ?5 chain of type IV collagen in the glomerular basement membranes. On genetic analysis for AS, de novo homozygote mutation (c.3605-2a > c) was seen in the gene encoding ?5 chain of type IV collagen (COL4A5) on the X chromosomes of maternal origin. This is the first case report of combined AS and KS diagnosed during infancy, and it indicates the need to consider the concurrent existence of these two disorders in infants with urine abnormalities, even in the absence of a family history.

    Polycystic ovary syndrome (PCOS) is a syndrome of variable combinations of menstrual irregularity, hirsutism or acne, and obesity. It can be diagnosed in adolescence and has early childhood antecedents. PCOS is the single most common endocrine cause of anovulatory infertility and a major risk factor for the metabolic syndrome and, in turn, development of type 2 diabetes mellitus (T2DM) in women. Thus, it appears that PCOS increases a womans risk of developing cardiovascular disease. Therefore, identifying girls at risk for PCOS and implementing treatment early in the development of PCOS may be an effective means of preventing some of the long-term complications associated with this syndrome. This article reviews the definition, clinical features, diagnosis, and treatment of PCOS. PMID:16085166

    2015-10-01

    Patients will experience a wide range of skin growths and changes over their lifetime. Family physicians should be able to distinguish potentially malignant from benign skin tumors. Most lesions can be diagnosed on the basis of history and clinical examination. Lesions that are suspicious for malignancy, those with changing characteristics, symptomatic lesions, and those that cause cosmetic problems may warrant medical therapy, a simple office procedure (e.g., excision, cryosurgery, laser ablation), or referral. Acrochordons are extremely common, small, and typically pedunculated benign neoplasms. Simple scissor or shave excision, electrodesiccation, or cryosurgery can be used for treatment. Sebaceous hyperplasia presents as asymptomatic, discrete, soft, pale yellow, shiny bumps on the forehead or cheeks, or near hair follicles. Except for cosmesis, they have no clinical significance. Lipomas are soft, flesh-colored nodules that are easily moveable under the overlying skin. Keratoacanthomas are rapidly growing, squamoproliferative benign tumors that resemble squamous cell carcinomas. Early simple excision is recommended. Pyogenic granuloma is a rapidly growing nodule that bleeds easily. Treatment includes laser ablation or shave excision with electrodesiccation of the base. Dermatofibromas are an idiopathic benign proliferation of fibroblasts. No treatment is required unless there is a change in size or color, bleeding, or irritation from trauma. Epidermal inclusion cysts can be treated by simple excision with removal of the cyst and cyst wall. Seborrheic keratoses and cherry angiomas generally do not require treatment. PMID:26447443

    2015-06-01

    Gout is an inflammatory, metabolically conditioned crystal-induced disease. Prevalence of gout is on the increase. In clinical practice it is frequently wrongly diagnosed and the therapy of acute attacks in particular is not adequate. The first part of the publication discusses diagnostic possibilities of gouty arthritis. First of all the advantage of the analysis of synovial exudate and of direct evidence of crystals in the polarization microscope is emphasized. If the material for crystallographic analysis is not available, it is necessary to use a combination of clinical criteria as specified e.g. in the recommendations of the European League Against Rheumatism (EULAR). The second part focuses on the therapy of gout which is divided into the periods of asymptomatic hyperuricemia, acute gouty attack, intercritical and chronic tophaceous gout. Asymptomatic hyperuricemia is only treated when uricemia greater than 540 µmol/l occur repeatedly, or when other risk factors and comorbidities are present. In the treatment of acute gouty attack its early start is more important than the choice of a preparation. Alternatives are NSA, colchicine or glucocorticoids. A newly regist-ered medicine for the treatment of refractory acute inflammation is the IL-1 inhibitor canakinumab. The treatment of hyperuricemia involves regimen and diet measures, abstinence and hypouricemic therapy. Available are the xanthine oxidase inhibitors, allopurinol and febuxostat; the latter is better suited for patients with moderate renal insufficiency. A new medicine for the treatment of severe refractory tophaceous gout is pegloticase.Key words: gouty arthritis - colchicine - nonsteroidal antirheumatic drugs. PMID:26258966

    Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior mesenteric artery thrombosis are common causes of AMI. Non-occlusive causes are less common, but vasculitis may be important, especially in younger people. Because of the unclear clinical presentation and non-specific laboratory findings, low clinical suspicion may lead to loss of valuable time. During this diagnostic delay, progression of ischemia to transmural bowel infarction with peritonitis and septicemia may further worsen patient outcomes. Several diagnostic modalities are used to assess possible AMI. Multi-detector row computed tomographic angiography is the current gold standard. Although computed tomographic angiography leads to an accurate diagnosis in many cases, early detection is a persistent problem. Because early diagnosis is vital to commence treatment, new diagnostic strategies are needed. A non-invasive simple biochemical test would be ideal to increase clinical suspicion of AMI and would improve patient selection for radiographic evaluation. Thus, AMI could be diagnosed earlier with follow-up computed tomographic angiography or high spatial magnetic resonance imaging. Experimental in vitro and in vivo studies show promise for alpha glutathione S transferase and intestinal fatty acid binding protein as markers for AMI. Future research must confirm the clinical utility of these biochemical markers in the diagnosis of mesenteric ischemia. PMID:23538325

    Pseudoaminopterin syndrome or aminopterin syndrome-like sine aminopterin (ASSA syndrome--OMIM 600325] is a rare autosomal recessive syndrome defined by characteristic dysmorphic features, skeletal defects, limb anomalies, cryptorchidism, and growth retardation. The syndrome owes its name to the fact that patients resemble the children exposed to aminopterin or to methotrexate, two dihydrofolate reductase inhibitors used for chemotherapy, or as an abortificient in early pregnancy. Ten patients have been described with pseudoaminopterin syndrome. Their phenotype is variable, and differs from the phenotype resulting from folic acid deprivation, leading to the notion that the pathogenesis may be more complex than simple vitamin deficiency. We report on an Algerian patient with pseudoaminopterin syndrome, review the previously reported cases and confirm that pseudoaminopterin syndrome does not result from a detectable contiguous gene imbalance as high resolution CGH array was normal in this child.

    The WHO declared tuberculosis (TB) a global emergency. An estimated 8-9 million new cases occur each year with 2-3 million deaths. Currently, TB is diagnosed mostly by chest-X ray and staining of the mycobacteria in sputum with a detection limit of 1x104 bacteria /ml. There is an urgent need for better diagnostic tools for TB especially for developing countries. We have validated the electronic nose from TD Technology for the detection of Mycobacterium tuberculosis by headspace analysis of 284 sputum samples from TB patients. We used linear discriminant function analysis resulting in a sensitivity of 75% a specificity of 67% and an accuracy of 69%. Further research is still required to improve the results by choosing more selective sensors and sampling techniques. We used a fast gas chromatography- mass spectrometry method (GC-MS). The automated procedure is based on the injection of sputum samples which are methylated inside the GC injector using thermally assisted hydrolysis and methylation (THM-GC-MS). Hexacosanoic acid in combination with tuberculostearic acid was found to be specific for the presence of M. tuberculosis. The detection limit was similar to microscopy. We found no false positives, all microscopy and culture positive samples were also found positive with the THM-GC-MS method. The detection of ribosomal RNA from the infecting organism offers great potential since rRNA molecules outnumber chromosomal DNA by a factor 1000. It thus may possible to detect the organism without amplification of the nucleic acids (NA). We used a capture and a tagged detector probe for the direct detection of M. tuberculosis in sputum. So far the detection limit is 1x106 bacteria / ml. Currently we are testing a Lab-On-A-Chip Interferometer detection system.

  14. Postconcussion Syndrome: A Review.

    PubMed

    Barlow, Karen M

    2016-01-01

    Postconcussion syndrome is a symptom complex with a wide range of somatic, cognitive, sleep, and affective features, and is the most common consequence of traumatic brain injury. Between 14% and 29% of children with mild traumatic brain injury will continue to have postconcussion symptoms at 3 months, but the pathophysiological mechanisms driving this is poorly understood. The relative contribution of injury factors to postconcussion syndrome decreases over time and, instead, premorbid factors become important predictors of symptom persistence by 3 to 6 months postinjury. The differential diagnoses include headache disorder, cervical injury, anxiety, depression, somatization, vestibular dysfunction, and visual dysfunction. The long-term outcome for most children is good, although there is significant morbidity in the short term. Management strategies target problematic symptoms such as headaches, sleep and mood disturbances, and cognitive complaints. PMID:25330797

    The diagnosis of bacterial endocarditis remains a challenge, as nearly half of cases develop in the absence of preexistent heart disease and known risk factors. Not infrequently, a blunted clinical course at onset can lead to erroneous diagnoses. We present the case of a 47-year-old previously healthy man in which a presumptive diagnosis of antiphospholipid syndrome was made based on the absence of echocardiographically detected heart involvement, a negative blood culture, normal C-reactive protein (CRP) levels, a positive lupus anticoagulant (LAC) test, and evidence of splenic infarcts. The patient eventually developed massive aortic endocarditic involvement, with blood cultures positive for Streptococcus bovis, and was referred for valvular replacement. This case not only reminds us of the diagnostic challenges of bacterial endocarditis, but also underlines the need for a critical application of antiphospholipid syndrome diagnostic criteria.

    2014-01-01

    Greater trochanteric pain is one of the common complaints in orthopedics. Frequent diagnoses include myofascial pain, trochanteric bursitis, tendinosis and rupture of the gluteus medius and minimus tendon, and external snapping hip. Furthermore, nerve entrapment like the piriformis syndrome must be considered in the differential diagnosis. This article summarizes essential diagnostic and therapeutic steps in greater trochanteric pain syndrome. Careful clinical evaluation, complemented with specific imaging studies and diagnostic infiltrations allows determination of the underlying pathology in most cases. Thereafter, specific nonsurgical treatment is indicated, with success rates of more than 90 %. Resistant cases and tendon ruptures may require surgical intervention, which can provide significant pain relief and functional improvement in most cases. PMID:24414233

    Abstract Problem Acquired immunodeficiency syndrome (AIDS)-related cytomegalovirus (CMV) retinitis continues to be a neglected source of blindness in resource-poor settings. The main issue is lack of capacity to diagnose CMV retinitis in the clinical setting where patients receive care and all other opportunistic infections are diagnosed. Approach We developed and implemented a four-day workshop to train clinicians working in human immunodeficiency virus (HIV) clinics how to perform binocular indirect ophthalmoscopy and diagnose CMV retinitis. Workshops comprised both classroom didactic instruction and direct clinical eye examinations in patients with advanced AIDS. Between 2007 and 2013, 14 workshops were conducted in China, Myanmar and the Russian Federation. Local setting Workshops were held with local clinicians at HIV clinics supported by nongovernmental organizations, public-sector municipal hospitals and provincial infectious disease referral hospitals. Each setting had limited or no access to locally- trained ophthalmologists, and an HIV-infected population with advanced disease. Relevant changes Clinicians learnt how to do binocular indirect ophthalmoscopy and to diagnose CMV retinitis. One year after the workshop, 32/38 trainees in Myanmar did systematic eye examination for early diagnosis of CMV retinitis as standard care for at-risk patients. In China and the Russian Federation, the success rates were lower, with 10/15 and 3/5 trainees, respectively, providing follow-up data. Lessons learnt Skills necessary for screening and diagnosis of CMV retinitis can be taught in a four-day task-oriented training workshop. Successful implementation depends on institutional support, ongoing training and technical support. The next challenge is to scale up this approach in other countries. PMID:25552774

    Gilles de la Tourette syndrome is a common neuropsychiatric disorder spectrum with tics as the defining feature. Comorbidities such as attention-deficit/hyperactivity disorder, obsessive-compulsive disorder, and autism spectrum disorder often complicate clinical presentation. Their recognition is paramount for the introduction of efficient treatment strategies to promote healthy development and good quality of life. Here, knowledge on the movement disorder of tics, the spectrum of associated comorbidities, and the list of differential diagnoses of tic disorders are summarized. Also, an account of the prevailing pathophysiologic models of tic generation is provided, and a concise update on contemporary treatment strategies is presented. PMID:25432726

    Myofascial pain syndrome (MPS) is a regional pain disorder caused by taut bands of muscle fibers in skeletal muscles called myofascial trigger points. MPS is a common disorder, often diagnosed and treated by physiatrists. Treatment strategies for MPS include exercises, patient education, and trigger point injection. Pharmacologic interventions are also common, and a variety of analgesics, antiinflammatories, antidepressants, and other medications are used in clinical practice. This review explores the various treatment options for MPS, including those therapies that target myofascial trigger points and common secondary symptoms. PMID:24787338

    Complex regional pain syndrome (CRPS) previously known as reflex sympathetic dystrophy is a chronic neurological disorder involving the limbs characterized by disabling pain, swelling, vasomotor instability, sudomotor abnormality, and impairment of motor function. CRPS is not uncommon after hand surgery and may complicate post-operative care. There is no specific diagnostic test for CRPS and the diagnosis is based on history, clinical examination, and supportive laboratory findings. Recent modifications to diagnostic criteria have enabled clinicians to diagnose this disease more consistently. This review gives a synopsis of CRPS and discusses the diagnosis, pathophysiology, and treatment options based on the limited evidence in the literature. PMID:22022040

    Wolfram syndrome (WS) is a rare autosomal recessive progressive neurodegenerative disorder, and it is mainly characterized by the presence of diabetes mellitus and optic atrophy. Other symptoms such as diabetes insipidus, deafness, and psychiatric disorders are less frequent. The WFS1 gene, responsible for the disease and encoding for a transmembrane protein called wolframin, was localized in 1998 on chromosome 4p16. In this report, we present a familial observation of Wolfram syndrome (parents and three children). The propositus was a 6-year-old girl with diabetes mellitus and progressive visual loss. Her family history showed a brother with diabetes mellitus, optic atrophy, and deafness since childhood and a sister with diabetes mellitus, optic atrophy, and bilateral hydronephrosis. Thus, association of these familial and personal symptoms is highly suggestive of Wolfram syndrome. The diagnosis was confirmed by molecular analysis (biology), which showed the presence of WFS1 homozygous mutations c.1113G>A (p.Trp371*) in the three siblings and a heterozygote mutation in the parents. Our observation has demonstrated that pediatricians should be aware of the possibility of Wolfram syndrome when diagnosing optic atrophy in diabetic children. PMID:25282462

    2015-10-01

    Doege-Potter syndrome is a rare paraneoplastic syndrome presenting as a hypoinsulinaemic hypoglycaemia from the ectopic secretion of a prohormone of insulin-like growth factor II (IGF-II) from a solitary fibrous tumour. Surgical resection is curative in the majority of cases. If, however, the diagnosis is not suspected and treatment is delayed, it can lead to hypoxic cerebral injury or death. The underlying tumour can be a benign or malignant pleural tumour but may be present in extrapleural sites. For a diagnosis of Doege-Potter syndrome, symptoms attributable to hypoglycaemia and low blood glucose levels should be present along with the secretion of prohormone IGF-II. We report a case of severe hypoglycaemia in a 76-year-old inpatient admitted for resection of a recurrent left-sided pleural tumour. Investigation revealed true hypoglycaemia and Doege-Potter syndrome was diagnosed. The tumour was completely resected and the patient made a full recovery with no further hypoglycaemic episodes.

    The catastrophic antiphospholipid syndrome (CAPS) is a life-threatening condition resulting from rapidly progressive widespread thromboses mainly affecting the microvasculature in the presence of antiphospholipid antibodies. Within a few days, the patients develop multiorgan failure with pulmonary distress, renal failure with severe hypertension, cerebral, cardiac, digestive or cutaneous involvement. CAPS develops in less than 1% of patients with antiphospholipid syndrome, either primary or associated with systemic lupus erythematosus. CAPS reveals the antiphospholipid syndrome in about 50% of cases. CAPS may be precipitated by infectious diseases, surgical procedures or discontinuation of anticoagulation. CAPS overall mortality rate has decreased in the past decade and is now around 30%. Within our hospital, it has been reduced to 10%. The main differential diagnoses are other thrombotic microangiopathies, and heparin-induced thrombocytopenia. The treatment of CAPS consists of the empirical association of anticoagulation and corticosteroids, plus plasma exchange or intravenous immunoglobulins. Cyclophosphamide is added in patients with systemic lupus erythematosus. The prevention of CAPS is based upon the adequate management of the perioperative period when surgery cannot be avoided, the prompt treatment of infections and the education of patients with antiphospholipid syndrome.

    Cushing syndrome and lipodystrophy syndromes share similar clinical features. This report describes an adolescent girl with newly diagnosed familial partial lipodystrophy type 2 (FPLD2) who was initially referred for Cushing syndrome. The type of abnormal fat deposition syndrome can be elucidated by careful clinical examination. FPLD2 can lead to type 2 diabetes mellitus and early cardiovascular events. Partial lipodystrophy presenting for the first time in adolescence can be mistaken for corticosteroid excess. Early diagnosis and preventative management of cardiovascular risk factors are crucial.

    Precordial catch syndrome was diagnosed in ten children whose primary complaint was chest pain. From published reports, nine characteristics of the pain were derived and their occurrence rate determined retrospectively in the ten patients. A close correspondence in type of pain was found between patients in previous reports and those I studied. Precordial catch pain typically is sudden, brief, periapical, easily localized, nonradiating, nonexertional, and importantly, intensified by inspiration. This study further validates the syndrome, reports its occurrence in children in the United States for the first time, and indicates more certainly the pain attributes one seeks for diagnosis.

    Taurodontism is a developmental anomaly that manifests as an alteration in a patient's internal morphology and is characterized by the lack of constriction at the level of the cementoenamel junction, which results in an apical extension of the pulp chamber that extends into the root area of a multiradicular tooth. This report presents a case of an otherwise healthy patient with 12 hypertaurodontic teeth, which were detected by using cone beam computed tomography (CBCT). It is essential to emphasize the importance of routine imaging examinations for diagnosing developmental dental anomalies such as taurodontism, as this condition is generally not found by routine oral examination, and is not necessarily restricted to syndromic patients. CBCT images contribute to the diagnosis of and treatment plan for taurodontism. PMID:24598505

    Abnormal hoarding of random items in the home associated with severe self-neglect and neglect of one's environment, Diogenes syndrome is transnosographic. It can affect all social classes, people without any diagnosed mental health condition or patients with psychosis or dementia, over 60s and young people. It is conveyed by self-exclusion at home, a "poor precarity" which leads to a loss of the ability to trust others and ask for help. PMID:26100289

    Patterson, Stephen M.

    2006-01-01

    The purpose of this review was to inform all medical health care professionals about cuboid syndrome, which has been described as difficult to recognize and is commonly misdiagnosed, by explaining the etiology of this syndrome, its clinical diagnosis in relation to differential diagnoses, commonly administered treatment techniques, and patient outcomes. A comprehensive review of the relevant literature was conducted with MEDLINE, EBSCO, and PubMed (1960 - Present) using the key words cuboid, cuboid syndrome, foot anatomy, tarsal bones, manual therapy, and manipulation. Medical professionals must be aware that any lateral foot and ankle pain may be the result of cuboid syndrome. Once properly diagnosed, cuboid syndrome responds exceptionally well to conservative treatment involving specific cuboid manipulation techniques. Other methods of conservative treatment including therapeutic modalities, therapeutic exercises, padding, and low dye taping techniques are used as adjuncts in the treatment of this syndrome. Immediately after the manipulation is performed, the patient may note a decrease or a complete cessation of their symptoms. Occasionally, if the patient has had symptoms for a longer duration, several manipulations may be warranted throughout the course of time. Due to the fact radiographic imaging is of little value, the diagnosis is largely based on the patient’s history and a collection of signs and symptoms associated with the condition. Additionally, an understanding of the etiology behind this syndrome is essential, aiding the clinician in the diagnosis and treatment of this syndrome. After the correct diagnosis is made and a proper treatment regimen is utilized, the prognosis is excellent. Key Points Define the poorly understood condition of cuboid syndrome. Provide an understanding of the anatomical structures involved. Provide an explanation as to the cause of this syndrome. Demonstrate ways to evaluate by making a differential diagnosis. To inform health care professionals about management and treatment of cuboid syndrome. PMID:24357955

  13. Creatine deficiency syndromes.

    PubMed

    Schulze, Andreas

    2013-01-01

    The lack of creatine in the central nervous system causes a severe but treatable neurological disease. Three inherited defects, AGAT, GAMT, and CrT deficiency, compromising synthesis and transport of creatine have been discovered recently. Together these so-called creatine deficiency syndromes (CDS) might represent the most frequent metabolic disorders with a primarily neurological phenotype. Patients with CDS present with global developmental delays, mental retardation, speech impairment especially affecting active language, seizures, extrapyramidal movement disorder, and autism spectrum disorder. The two defects in the creatine synthesis, AGAT and GAMT, are autosomal recessive disorders. They can be diagnosed by analysis of the creatine, guanidinoacetate, and creatinine in body fluids. Treatment is available and, especially when introduced in infancy, has a good outcome. The defect of creatine transport, CrT, is an X-linked condition and perhaps the most frequent reasons for X-linked mental retardation. Diagnosis is made by an increased ratio of creatine to creatinine in urine, but successful treatment still needs to be explored. CDS are under-diagnosed because easy to miss in standard diagnostic workup. Because CDS represent a frequent cause of cognitive and neurological impairment that is treatable they warrant consideration in the workup for genetic mental retardation syndromes, for intractable seizure disorders, and for neurological diseases with a predominant lack of active speech.

    Cryptococcal pneumonia usually occurs in immunocompromised patients with malignancy, acquired immune deficiency syndrome, organ transplantations, immunosuppressive chemotherapies, catheter insertion, or dialysis. It can be diagnosed by gaining tissues in lung parenchyma or detecting antigen in blood or bronchoalveolar lavage fluid. Here we report an immunocompetent 32-year-old male patient with diabetes mellitus diagnosed with cryptococcal pneumonia after a ultrasound-guided percutaneous supraclavicular lymph node core needle biopsy. We treated him with fluconazole at 400 mg/day for 9 months according to the guideline. This is the first case that cryptococcal pneumonia was diagnosed from a percutaneous lymph node biopsy in South Korea. PMID:26175785

    Apert's syndrome (AS), a form of acrocephalosyndactyly, is a rare congenital disorder with autosomal dominant mode of transmission; characterized by craniosynostosis, midface hypoplasia, and syndactyly of hands and feet. The rarity of the syndrome and similarity of features with other craniosynostosis syndromes makes it a diagnostic dilemma. Genetic counseling and early intervention form an essential part of treatment. Because of the paucity of reported cases in Indian literature and typical features in oral cavity, a dentist should be competent to diagnose and form a part of the multidisciplinary management team. Here, we report a case of a 14-year-old boy with AS. PMID:24250097

    The idiopathic hypereosinophilic syndrome is a part of the yet rather unknown diseases and the aetiology remains at the least hypothetical. This syndrome is characterized by a variable hypereosinophilemia as well as a massive infiltration of several organs by mature eosinophils, causing an important tissue damage leading to organ dysfunctions and resulting in the patient death. In this reported case, the acute idiopathic hypereosinophilic syndrome was diagnosed in a 4-year rottweiler female dog based on an increased eosinophilemia and the infiltration of stomach, small intestine, colon, pancreas, spleen, ganglions, skin, lungs and bone marrow by mature eosinophiles. The acute development of the disease precluded any therapeutical hope success. PMID:18085165

    The baboon syndrome is a form of systemic contact dermatitis with skin eruptions in the area of the buttocks and major flexures. Inhalation of mercury vapor causes this rare but distinctive eruption. Broken thermometers are the usual sources of exposure. We hereby present a 14-year-old boy diagnosed with baboon syndrome coexistence with vitiligo, due to broken thermometers. In our case, it was interesting that erythematous eruptions were more evident on the vitiliginous side of the trunk. To our knowledge, there have been no reports in the literature of baboon syndrome and vitiligo coexistence. PMID:19950853

  19. Barth syndrome

    PubMed Central

    2013-01-01

    First described in 1983, Barth syndrome (BTHS) is widely regarded as a rare X-linked genetic disease characterised by cardiomyopathy (CM), skeletal myopathy, growth delay, neutropenia and increased urinary excretion of 3-methylglutaconic acid (3-MGCA). Fewer than 200 living males are known worldwide, but evidence is accumulating that the disorder is substantially under-diagnosed. Clinical features include variable combinations of the following wide spectrum: dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), endocardial fibroelastosis (EFE), left ventricular non-compaction (LVNC), ventricular arrhythmia, sudden cardiac death, prolonged QTc interval, delayed motor milestones, proximal myopathy, lethargy and fatigue, neutropenia (absent to severe; persistent, intermittent or perfectly cyclical), compensatory monocytosis, recurrent bacterial infection, hypoglycaemia, lactic acidosis, growth and pubertal delay, feeding problems, failure to thrive, episodic diarrhoea, characteristic facies, and X-linked family history. Historically regarded as a cardiac disease, BTHS is now considered a multi-system disorder which may be first seen by many different specialists or generalists. Phenotypic breadth and variability present a major challenge to the diagnostician: some children with BTHS have never been neutropenic, whereas others lack increased 3-MGCA and a minority has occult or absent CM. Furthermore, BTHS was first described in 2010 as an unrecognised cause of fetal death. Disabling mutations or deletions of the tafazzin (TAZ) gene, located at Xq28, cause the disorder by reducing remodeling of cardiolipin, a principal phospholipid of the inner mitochondrial membrane. A definitive biochemical test, based on detecting abnormal ratios of different cardiolipin species, was first described in 2008. Key areas of differential diagnosis include metabolic and viral cardiomyopathies, mitochondrial diseases, and many causes of neutropenia and recurrent male miscarriage and stillbirth. Cardiolipin testing and TAZ sequencing now provide relatively rapid diagnostic testing, both prospectively and retrospectively, from a range of fresh or stored tissues, blood or neonatal bloodspots. TAZ sequencing also allows female carrier detection and antenatal screening. Management of BTHS includes medical therapy of CM, cardiac transplantation (in 14% of patients), antibiotic prophylaxis and granulocyte colony-stimulating factor (G-CSF) therapy. Multidisciplinary teams/clinics are essential for minimising hospital attendances and allowing many more individuals with BTHS to live into adulthood. PMID:23398819

    Aims and method To explore the current salience of brain fag as a nosological, diagnostic and clinical construct in modern West African psychiatry. A semi-structured questionnaire and vignette based on classical symptoms of brain fag syndrome were used to explore current knowledge, explanatory models and practice among Nigerian psychiatrists. Results Of 102 psychiatrists who responded, 98% recognised the term brain fag syndrome and most recognised the scenario presented. However, only 22% made a diagnosis of brain fag syndrome in their practice preferring diagnoses of anxiety, affective and somatic disorders. Clinical implications A decreasing number of Nigerian psychiatrists are making a diagnosis of brain fag syndrome. We found strong evidence of nosological and diagnostic decline in the syndrome in its place of birth. This may signal the early extinction of this disorder or nosological metamorphosis from a culture-bound syndrome in West African psychiatric practice. PMID:26755946

    Introduction: In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. Case Presentation: The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. Conclusions: The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment. PMID:26949693

    Simultaneous video (closed circuit television [CCTV]) and EEG recordings are important in the differentiation of epileptic and non-epileptic paroxysmal episodes and in the classification of epilepsy syndromes. An additional benefit from the observation of the child on CCTV is the possible identification of specific clinical, including genetic, conditions. This three-year prospective study of 2780 consecutive children undergoing routine EEG investigations identified 17 conditions that had not previously been diagnosed by the clinicians who had requested the EEG.

    2016-01-01

    Inherited bone marrow failure syndromes comprise a series of disorders caused by various gene mutations. Genetic tests were formerly difficult to perform because of the large size and number of causative genes. However, recent advances in next-generation sequencing has enabled simultaneous testing of all causative genes to be performed at an acceptable cost. We collaboratively conducted a series of whole-exome sequencing studies of patients with inherited bone marrow failure syndromes and discovered RPS27/RPL27 and FANCT as causative genes of Diamond-Blackfan anemia and Fanconi anemia, respectively. Furthermore, we established a target gene sequencing system to cover 189 genes associated with pediatric blood diseases to assist genetic diagnoses in clinical practice. In this review, discovery of new causative genes and possible roles of next-generation sequencing in the genetic diagnosis of inherited bone marrow failure syndromes are discussed. PMID:26935625

    The X-linked lymphoproliferative syndrome is triggered by Epstein-Barr virus infection and results in fatal mononucleosis, immunodeficiency, and lymphoproliferative disorders. This study shows that the mutation responsible for X-linked lymphoproliferative syndrome is genetically linked to a restriction fragment length polymorphism detected with the DXS42 probe (from Xq24-q27). The most likely recombination frequency between the loci is 4%, and the associated logarithm of the odds is 5.26. Haplotype analysis using flanking restriction fragment length polymorphism markers indicates that the locus for X-linked lymphoproliferative syndrome is distal to probe DXS42 but proximal to probe DXS99 (from Xq26-q27). It is now possible to predict which members of a family with X-linked lymphoproliferative syndrome are carrier females and to diagnose the syndrome prenatally.

    2008-01-01

    Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs), odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies). Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm) are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull) are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling). Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome). Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser ablation, photodynamic therapy and topical chemotherapy. Radiotherapy should be avoided. Vitamin A analogs may play a preventive role against development of new BCCs. Life expectancy in NBCCS is not significantly altered but morbidity from complications can be substantial. Regular follow-up by a multi-specialist team (dermatologist, neurologist and odontologist) should be offered. Patients with NBCCS should strictly avoid an excessive sun exposure. PMID:19032739

    Parental immigration has been suggested as a possible risk factor for autism spectrum disorders (ASD), but findings have been inconsistent. Very few studies have focused specifically on Asperger's syndrome. The aim of this study was to examine the association between maternal and paternal immigration and the diagnosis of Asperger's syndrome in offspring. The study was a nested case-control study based on a national birth cohort in Finland. Children born in 1987-2005 and diagnosed with Asperger's syndrome by the year 2007 were identified from the Finnish Hospital Discharge Register (N = 1,783). Four matched controls for each case were selected from the Finnish Medical Birth Register (N = 7,106). Information on maternal and paternal country of birth and mother tongue was collected from the Finnish Central Population Register. The study showed that children whose parents are both immigrants have a significantly lower likelihood of being diagnosed with Asperger's syndrome than those with two Finnish parents [adjusted odds ratio (aOR) 0.2, 95 % confidence interval (CI) 0.1-0.4]. No significant associations were found between having only one immigrant parent and the diagnosis of Asperger's syndrome. A regional analysis showed a significantly decreased likelihood of the diagnosis of Asperger's syndrome in children whose mother (aOR 0.1, 95 % CI 0.01-0.5) or father (aOR 0.2, 95 % CI 0.05-0.5) was born in Sub-Saharan Africa. The findings may help in identifying risk factors for different ASD subtypes. On the other hand, they might reflect service use of immigrant families in Finland. PMID:25381114

    2015-10-01

    For diagnosing of polycystic ovary syndrome (PCOS) it is currently recommended to follow the ESHRE criteria. For diagnosis according to them two of the following three symptoms are sufficient: 1. morphology of polycystic ovaria, 2. clinical manifestations of hyperandrogenism or laboratory proof of hyperandrogenemia, and 3. oligo-anovulation. PCOS is a complex disorder in whose pathogenesis genetic and environmental effects interact. It is not a gynecological disorder alone, the syndrome is accompanied by insulin resistance which leads to increased incidence of type 2 diabetes mellitus and impaired glucose tolerance (4 times and twice, independently of BMI). Also gestational DM occurs more frequently. Dyslipidemia, arterial hypertension, elevated CRP and homocysteine levels, endothelial dysfunction and greater intima-media thickness are also more frequent. It is not quite clear, however, whether women with PCOS suffer cardiovascular events more frequently as well. More often than is accidental PCOS is associated with depression, anxiety and eating disorders, further with nonalcoholic steatohepatitis and with the sleep apnoea syndrome - especially in obese women. Therapeutic measures include non-pharmacological methods - lifestyle adjustments focused on weight reduction in obese individuals, cosmetic measures for dermatologic manifestation of hyperandrogenism, in particular laser and pharmacotherapy (combined hormonal contraceptives and antiandrogens). Menstrual irregularities can be treated with contraceptives or cyclical administration of gestagens, also metformin can be used.Key words: antiandrogens - diabetes mellitus - hormonal contraception - insulin resistance - ischemic heart disease - metformin.

    Marshall syndrome (ectodermal dysplasia) was diagnosed in a 14-year-old boy and is thought to be the first case reported from West Africa. Because of the saddle-nose deformity and bilateral cataracts all patients suspected of having congenital syphilis should be investigated for ocular or auditory defects, which would confirm the diagnosis of ectodermal dysplasia.

    Heerfordt's syndrome is a rare manifestation of sarcoidosis characterized by the presence of facial nerve palsy, parotid gland enlargement, anterior uveitis, and low grade fever. Two cases of Heerfordt's syndrome and a literature review are presented. Case  1. A 53-year-old man presented with swelling of his right eyelid, right facial nerve palsy, and swelling of his right parotid gland. A biopsy specimen from the swollen eyelid indicated sarcoidosis and he was diagnosed with incomplete Heerfordt's syndrome based on the absence of uveitis. His symptoms were improved by corticosteroid therapy. Case  2. A 55-year-old woman presented with left facial nerve palsy, bilateral hearing loss, and swelling of her bilateral parotid glands. She had been previously diagnosed with uveitis and bilateral hilar lymphadenopathy. Although no histological confirmation was performed, she was diagnosed with complete Heerfordt's syndrome on the basis of her clinical symptoms. Swelling of the bilateral parotid glands and left facial nerve palsy were improved immediately by corticosteroid therapy. Sarcoidosis is a relatively uncommon disease for the otolaryngologist. However, the otolaryngologist may encounter Heerfordt's syndrome as this syndrome presents with facial nerve palsy and swelling of the parotid gland. Therefore, we otolaryngologists should diagnose and treat Heerfordt's syndrome appropriately in cooperation with pneumologists and ophthalmologists. PMID:26885424

  17. Brown's syndrome: diagnosis and management.

    PURPOSE: To better understand the various etiologies of Brown's syndrome, define specific clinical characteristics of Brown's syndrome, describe the natural history of Brown's syndrome, and evaluate the longterm outcome of a novel surgical procedure: the silicone tendon expander. Also, to utilize a computer model to simulate the pattern of strabismus seen clinically with Brown's syndrome and manipulate the model to show potential surgical outcomes of the silicone tendon expander. METHODS: Charts were reviewed on patients with the diagnosis of Brown's syndrome seen at a children's hospital ophthalmology clinic from 1982 to 1997, or seen in the author's private practice. Objective fundus torsion was assessed in up gaze, down gaze, and primary position in 7 Brown's syndrome patients and in 4 patients with primary superior oblique overaction. A fax survey was taken of members of the American Association of Ophthalmology and Strabismus (AAPOS) listed in the 1997-1998 directory regarding their results using the silicone tendon expander procedure for the treatment of Brown's syndrome. A computer model of Brown's syndrome was created using the Orbit 1.8 program by simulating a shortened superior oblique tendon or by changing stretch sensitivity to create an inelastic muscle. RESULTS: A total of 96 patients were studied: 85 with Brown's syndrome (38 with congenital and 47 with acquired disease), 6 with masquerade syndromes, 1 with Brown's syndrome operated on elsewhere, and 4 with primary superior oblique overaction in the torsion study. Three original clinical observations were made: 1. Significant limitation of elevation in abduction occurs in 70% of Brown's syndrome cases surgically verified as caused by a tight superior oblique tendon. Contralateral pseudo-inferior oblique overaction is associated with limited elevation in abduction. 2. Traumatic Brown's syndrome cases have larger hypotropias than nontraumatic cases (P < .001). There was no significant hypotropia in primary position in 56 (76%) of 74 congenital and nontraumatic acquired cases despite severe limitation of elevation. 3. Of 7 patients with Brown's syndrome, 6 had no significant fundus torsion in primary position, but had significant (+2 to +3) intorsion in up gaze. Spontaneous resolution occurred in approximately 16% of acquired nontraumatic Brown's syndrome patients. The silicone tendon expander was used on 15 patients, 13 (87%) were corrected with 1 surgery and 14 (93%) with 2 surgeries. The only failure was a Brown's syndrome not caused by superior oblique pathology. Five of the silicone tendon expander patients had at least 5 years follow-up (range, 5 to 11 years). Four (80%) of the 5 patients had an excellent outcome with 1 surgery, final results graded between 9 and 10 (on a scale of 1-10, 10 is best). The fifth patient had a consecutive superior oblique paresis and a good outcome after a recession of the ipsilateral inferior oblique muscle. The AAPOS survey had a mean outcome score of 7.3, with 65% between 8 and 10. There were 9 (6%) complications reported: 4 related to scarring and 5 extrusions of the implant. Three of the 5 extrusions were reported from the same surgeon. The computer model of an inelastic superior oblique muscle-tendon complex best simulated the motility pattern of Brown's syndrome with severe limitation of elevation in adduction, mild limitation of elevation in abduction, minimal hypotropia in primary position, no superior oblique overaction, and intorsion in up gaze. CONCLUSIONS: The presence of mild to moderate limitation of elevation in abduction is common, and its presence does not eliminate the diagnosis of Brown's syndrome. The majority of Brown's syndrome patients have a pattern of strabismus consistent with an inelastic superior oblique muscle-tendon complex that does not extend, but can contract normally; not the presence of a short tendon. The presence of inelastic or tethered superior oblique muscle-tendon can be diagnosed without forced duction testing by observing the pattern of strabismus including torsion. Because of

    OBJECTIVE--To study prevalence of Turner's syndrome in Denmark and to assess validity of prenatal diagnosis. DESIGN--Study of data on prenatal and postnatal Turner's syndrome in Danish Cytogenetic Central Register. SUBJECTS--All registered Turner's syndrome karyotypes (100 prenatal cases and 215 postnatal cases) during 1970-93. MAIN OUTCOME MEASURES--Prevalence of Turner's syndrome karyotypes among prenatally tested fetuses and Turner's syndrome among liveborn infants. RESULTS--Among infant girls, prevalence of Turner's syndrome was 32/100,000. Among female fetuses tested by amniocentesis, prevalence of Turner's syndrome karyotypes was 176/100,000 (relative risk of syndrome, 6.74 compared with prevalence among untested pregnancies). Among female fetuses tested by chorion villus sampling, prevalence of syndrome karyotypes was 392/100,000 (relative risk, 16.8). We excluded prenatal tests referred because of results of ultrasound scanning: among fetuses tested by amniocentesis revised relative risk was 5.68, while revised relative risk among fetuses tested by chorion villus sampling was 13.3. For 29 fetuses with prenatal diagnosis of possible Turner's syndrome, pregnancy was allowed to continue and 24 children were live born. Thirteen of these children were karyotyped postnatally, and diagnosis of Turner's syndrome had to be revised for eight, seven being normal girls and one boy. This gives tentative predictive value of amniocentesis in diagnosing Turner's syndrome of between 21% and 67%. There was no significant relation between mother's age and risk of Turner's syndrome. CONCLUSIONS--Discrepancy between prenatal and postnatal prevalence of Turner's syndrome challenges specificity of prenatal examination in diagnosing Turner's syndrome. PMID:8555850

    Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants. PMID:26636160

    Hypertensive disorders of pregnancy are one of the most common complications of pregnancy, but one of the most serious expressions of this pathology is HELLP syndrome. The HELLP syndrome is characterized by the presence of hypertension disorder more a triad: microangiopathic hemolysis, elevated liver enzymes and low platelet count. Patient with HELLP syndrome is associated with increased maternal risk complications such as: cerebral hemorrhage, retinal detachment, hematoma/ hepatic rupture, acute renal failure, disseminated intravascular coagulation, placental abruption and therefore a maternal death. For all these reasons it is recommended to search for findings of HELLP syndrome in patients with hypertensive disorder of pregnancy. The main clinical confusion of HELLP syndrome is acute fatty liver of pregnancy, however there are parameters that help correct identification. The presence of HELLP syndrome involves a rapid termination of pregnancy and the administration of corticosteroids does not improve maternal morbidity and mortality but may help raise the platelet count, thus decreasing the need for transfusion and shorten hospital stay. Much of the decline in maternal morbidity and mortality associated with hypertensive disorders of pregnancy is in proper diagnosis and effective management of HELLP syndrome. PMID:26016316

    Because syndrome designations permit the collection of data, they are much more than just lables. As new syndromes become delineated, their names connote (1) their phenotypic spectra, (2) their natural histories, and (3) their modes of inheritance or risk of recurrence. Various methods for designating new syndromes are reviewed, including naming them after (1) the basic defect, (2) an eponym, (3) one or more striking features, (4) an acronym, (5) a numeral, (6) a geographic term, and (7) some combination of the above. None of these systems of nomenclature is without fault. The advantages and disadvantages of each are discussed. PMID:957375

    Reversible cerebral vasoconstriction syndrome (RCVS) is a group of syndromes characterized by reversible segmental constriction of cerebral arteries. Posterior reversible encephalopathy syndrome (PRES) is another clinical-radiologic syndrome characterized by reversible, posterior-predominant brain edema. Although the exact causes of these reversible syndromes are poorly understood, these entities may share some common pathophysiologic elements leading to hemorrhagic strokes and rarely, deep intracerebral hemorrhage (ICH). Recent studies have suggested that endothelial dysfunction is a common pathophysiologic factor associated with these syndromes. We report on two young female patients who presented with deep ICH and were later diagnosed as RCVS and PRES. Both patients suffered from vasoconstriction and delayed ischemic stroke. Early detection of distinguishing clinical-radiologic features associated with these reversible syndromes and removing triggers would facilitate successful treatment with no complications.

    Endobronchial ultrasound (EBUS) imaging is commonly used to evaluate and aid in biopsy of mediastinal lymph nodes. Pulmonary arteries are readily viewable with this type of imaging modality. We present a case report of a pulmonary embolism (PE) diagnosed by EBUS. Our patient had no smoking history and presented with respiratory and constitutional symptoms, urinary retention, and leg weakness suspicious for malignancy with metastasis to spine. Chest computed tomography (CT) was suggestive of lung carcinoma and specifically showed no PE. EBUS with TBNA was requested for tissue diagnosis. A mobile filling defect consistent with a PE was observed and reported to primary team. Follow-up chest CT showed an acute PE which confirmed the diagnosis originally made by EBUS. Bronchoscopists should be aware of potential to diagnose a PE while performing EBUS. Additionally, there may be a role in using EBUS specifically to diagnose a PE in the right patient population.

A description of the considerable physical and emotional changes experienced by transition-aged youths provides a foundation for exploring the pressures and challenges compounded by mental health issues and substance abuse. Programs that provide intensive support throughout the transition years pay valuable dividends. However, transition-aged youths with dual diagnoses of mental disorders and substance abuse find themselves faced with limited or nonexistent options. There is a confusing lack of continuity and consistency of supports and services, which complicates the already perplexing circumstances that beleaguer the lives of young adults with dual diagnoses.

    Multiple fault diagnosis is a difficult problem for dynamic systems. Due to fault masking, compensation, and relative time of fault occurrence, multiple faults can manifest in many different ways as observable fault signature sequences. This decreases diagnosability of multiple faults, and therefore leads to a loss in effectiveness of the fault isolation step. We develop a qualitative, event-based, multiple fault isolation framework, and derive several notions of multiple fault diagnosability. We show that using Possible Conflicts, a model decomposition technique that decouples faults from residuals, we can significantly improve the diagnosability of multiple faults compared to an approach using a single global model. We demonstrate these concepts and provide results using a multi-tank system as a case study.

    Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts), the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome. PMID:25506011

Examples include Fanconi anemia, dyskeratosis congenita, Diamond-Blackfan anemia, thrombocytopenia absent radii syndrome, severe congenital neutropenia, and Shwachman-Diamond syndrome. The management of these disorders was once the exclusive domain of pediatric subspecialists, but increasingly physicians who care for adults are being called upon to diagnose or treat these conditions. Through a series of patient vignettes, we highlight the clinical manifestations of inherited bone marrow failure syndromes in adolescents and young adults.

    This review recognizes that, given the various complexities associated with the condition, no pat answers can be given to fit every patient with the compartment syndrome. The authors first give a definition of the syndrome, together with a brief account of how this self-perpetuating pathologic cycle is triggered. Next, they delineate specific anatomical features of compartments that are likely to be involved, and follow this with an inventory of symptoms and signs to look for in suspected cases. After sorting out the entities that can mimic the compartment syndrome, the authors describe three essential techniques of measuring tissue pressure, which can prove invaluable in diagnosing the compartment syndrome.

    Malignant mesothelioma is a rare malignant neoplasm that arises from mesothelial surfaces of the pleural cavity, peritoneal cavity, tunica vaginalis, or pericardium. Typically, pleural fluid cytology or closed pleural biopsy, surgical intervention (video thoracoscopic biopsy or open thoracotomy) is conducted to obtain pleural tissue specimens. However, endobronchial lesions are rarely seen and cases diagnosed from bronchoscopic biopsy are also rarely reported. We reported the case of a 77-year-old male who was diagnosed as malignant mesothelioma on bronchoscopic biopsy from obstructing masses of the endobronchial lesion. PMID:26175790

    Purpose: The moyamoya syndrome is an uncommon late complication after radiotherapy (RT). Methods and Materials: A PubMed search of English-language articles, with radiation, radiotherapy, and moyamoya syndrome used as search key words, yielded 33 articles from 1967 to 2002. Results: The series included 54 patients with a median age at initial RT of 3.8 years (range, 0.4 to 47). Age at RT was less than 5 years in 56.3%, 5 to 10 years in 22.9%, 11 to 20 years in 8.3%, 21 to 30 years in 6.3%, 31 to 40 years in 2.1%, and 41 to 50 years in 4.2%. Fourteen of 54 patients (25.9%) were diagnosed with neurofibromatosis type 1 (NF-1). The most common tumor treated with RT was low-grade glioma in 37 tumors (68.5%) of which 29 were optic-pathway glioma. The average RT dose was 46.5 Gy (range, 22-120 Gy). For NF-1-positive patients, the average RT dose was 46.5 Gy, and for NF-1-negative patients, it was 58.1 Gy. The median latent period for development of moyamoya syndrome was 40 months after RT (range, 4-240). Radiation-induced moyamoya syndrome occurred in 27.7% of patients by 2 years, 53.2% of patients by 4 years, 74.5% of patients by 6 years, and 95.7% of patients by 12 years after RT. Conclusions: Patients who received RT to the parasellar region at a young age (<5 years) are the most susceptible to moyamoya syndrome. The incidence for moyamoya syndrome continues to increase with time, with half of cases occurring within 4 years of RT and 95% of cases occurring within 12 years. Patients with NF-1 have a lower radiation-dose threshold for development of moyamoya syndrome.

    Hepatopulmonary syndrome is characterized by the presence of liver disease, pulmonary vascular dilatations, and arterial hypoxemia. It is usually associated with cirrhosis of any origin, but has been described in other liver diseases, both acute and chronic, and not always associated with portal hypertension. The gold standard method to detect pulmonary vascular dilations is contrast enhancement echocardiography with saline and is essential for the diagnosis of hepatopulmonary syndrome. These dilatations reflect changes in the pulmonary microvasculature (vasodilatation, intravascular monocyte accumulation, and angiogenesis) and induce a ventilation/perfusion mismatch, or even true intrapulmonary shunts, which eventually trigger hypoxemia. This syndrome worsens patients' prognosis and impairs their quality of life and may lead to the need for liver transplantation, which is the only effective and definitive treatment. In this article, we review the etiological, pathophysiological, clinical and therapeutic features of this syndrome. PMID:25840463
