    We studied noise characteristics of a nanocomposite of polyimide (PI) and phenyl-C61-butyric acid methyl ester (PCBM) (denoted as PI:PCBM), a composite for the organic nonvolatile resistive memory material. The current fluctuations were investigated over a bias range that covers various intermediate resistive states and negative differential resistance (NDR) in organic nanocomposite unipolar resistive memory devices. From the analysis of the 1/f(γ) type noises, scaling behavior between the relative noise power spectral density S̃ and resistance R was observed, indicating a percolating behavior. Considering a linear rate equation of the charge trapping-detrapping at traps, the percolation behavior and NDR could be understood by the modulation of the conductive phase fraction φ with an external bias. This study can enhance the understanding of the NDR phenomena in organic nanocomposite unipolar resistive memory devices in terms of the current path formation and the memory switching.

    In this letter, we perform a complete and in-depth analysis of Lorentzian noises, such as those arising from [Formula: see text] and [Formula: see text] channel kinetics, in order to identify the source of [Formula: see text]-type noise in neurological membranes. We prove that the autocovariance of Lorentzian noise depends solely on the eigenvalues (time constants) of the kinetic matrix but that the Lorentzian weighting coefficients depend entirely on the eigenvectors of this matrix. We then show that there are rotations of the kinetic eigenvectors that send any initial weights to any target weights without altering the time constants. In particular, we show there are target weights for which the resulting Lorenztian noise has an approximately [Formula: see text]-type spectrum. We justify these kinetic rotations by introducing a quantum mechanical formulation of membrane stochastics, hidden quantum activated-measurement models, and prove that these quantum models are probabilistically indistinguishable from the classical hidden Markov models typically used for ion channel stochastics. The quantum dividend obtained by replacing classical with quantum membranes is that rotations of the Lorentzian weights become simple readjustments of the quantum state without any change to the laboratory-determined kinetic and conductance parameters. Moreover, the quantum formalism allows us to model the activation energy of a membrane, and we show that maximizing entropy under constrained activation energy yields the previous [Formula: see text]-type Lorentzian weights, in which the spectral exponent [Formula: see text] is a Lagrange multiplier for the energy constraint. Thus, we provide a plausible neurophysical mechanism by which channel and membrane kinetics can give rise to [Formula: see text]-type noise (something that has been occasionally denied in the literature), as well as a realistic and experimentally testable explanation for the numerical values of the spectral

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive multisystem disorder of pigmentary dilution of skin, silver gray hair, variable immunodeficiency, neurological impairment, and abnormal accumulation of melanosomes in melanocytes. GS type 3 is characterized by hypomelanosis with no immunological and neurological manifestation. Prognosis is very good in type 3 GS and usually require no active intervention, as opposed to type 1 and 2 where early diagnosis and treatment plays a crucial role in patient's survival. The characteristic phenotypic appearance, especially the pigment dilution of the patient's hair, is emphasized here.

    Charcot-Marie-Tooth neuropathy (CMT) 2E/1F is caused by mutations in the neurofilament light-chain polypeptide (NEFL) gene. Giant axons are a histological hallmark frequently seen in nerves of patients with CMT2E. We describe the case of a 43-year-old patient with a painful, predominantly sensory neuropathy. The patient's sural nerve biopsy showed multiple giant axons. Genetic sequencing of the NEFL gene revealed that the patient was heterozygous for an altered sequence of the gene, c.816C>G, p.Asn272Lys, which has not yet been described in CMT2E/1F. In contrast to other cases of CMT2E/1F, where motor symptoms are predominant, pain was the most disabling symptom in this patient. Muscle Nerve 55: 752-755, 2017. © 2016 Wiley Periodicals, Inc.

    Polyglandular Autoimmune Syndrom type 1 (PAS-1) or Autoimmune PolyEndocrinopathy Candidiasis-Ectodermal-Dystrophy (APECED) is a rare recessive autosomal disease related to Autoimmune Regulator (AIRE) gene mutations. AIRE is mainly implicated in central and peripheric immune tolerance. Diagnosis was classically based on presence of at least two out of three "majors" criterions of Whitaker's triad (candidiasis, autoimmune hypoparathyroidism and adrenal insufficiency). Presence of one criterion was sufficient when a sibling was previously diagnosed. However, some atypic or poorly symptomatic variants do not correspond to these criterions. As a matter of fact, digestive (malabsorption, pernicious anemia, hepatitis), cutaneous (alopecia, vitiligo, enamel dysplasia) or ophtalmological (keratitis) components could prevail. In these cases, diagnosis could be made by molecular genetics. Prognosis is influenced by genetic (AIRE mutations, HLA), hormonal and environmental (infections) factors. Potentially letal components (hepatitis and severe malabsorption) could be treated by immunosuppressors. Candidiasis and other infections should be carefully screened and treated before beginning those therapies, in order to avoid severe systemic infections. Copyright © 2012 Elsevier Masson SAS.

    Full Text Available Mirizzi Syndrome type IV is an extremely rare condition, which is confused with the diagnosis of cholangiocarcinoma in many cases. This report describes a case of a forty-three-year old patient, who was forwarded to our department of general surgery with a high suspicion of a choledochal neoplasic lesion. During the hospitalization he was diagnosed with Mirizzi Syndrome type IV. We concisely describe the case and the literature review about this pathology.

    2007-01-01

    Ehlers-Danlos syndrome type IV, the vascular type of Ehlers-Danlos syndromes (EDS), is an inherited connective tissue disorder defined by characteristic facial features (acrogeria) in most patients, translucent skin with highly visible subcutaneous vessels on the trunk and lower back, easy bruising, and severe arterial, digestive and uterine complications, which are rarely, if at all, observed in the other forms of EDS. The estimated prevalence for all EDS varies between 1/10,000 and 1/25,000, EDS type IV representing approximately 5 to 10% of cases. The vascular complications may affect all anatomical areas, with a tendency toward arteries of large and medium diameter. Dissections of the vertebral arteries and the carotids in their extra- and intra-cranial segments (carotid-cavernous fistulae) are typical. There is a high risk of recurrent colonic perforations. Pregnancy increases the likelihood of a uterine or vascular rupture. EDS type IV is inherited as an autosomal dominant trait that is caused by mutations in the COL3A1 gene coding for type III procollagen. Diagnosis is based on clinical signs, non-invasive imaging, and the identification of a mutation of the COL3A1 gene. In childhood, coagulation disorders and Silverman's syndrome are the main differential diagnoses; in adulthood, the differential diagnosis includes other Ehlers-Danlos syndromes, Marfan syndrome and Loeys-Dietz syndrome. Prenatal diagnosis can be considered in families where the mutation is known. Choriocentesis or amniocentesis, however, may entail risk for the pregnant woman. In the absence of specific treatment for EDS type IV, medical intervention should be focused on symptomatic treatment and prophylactic measures. Arterial, digestive or uterine complications require immediate hospitalisation, observation in an intensive care unit. Invasive imaging techniques are contraindicated. Conservative approach is usually recommended when caring for a vascular complication in a patient suffering

    2009-02-01

    Full Text Available We report a rare case of Bartter's syndrome in a 35-year-old woman with type 2 diabetes mellitus. The patient presented with leg weakness, fatigue, polyuria and polydipsia. Hypokalemia, metabolic alkalosis, and high renin and aldosterone concentrations were present, but the patient was normotensive. Gitelman's syndrome was excluded because of the presence of hypercalciuria, secondary hyperparathyroidism and bilateral nephrocalcinosis. The patient's condition improved upon administration of a prostaglandin synthetase inhibitor (acemetacin, oral potassium chloride and potassium-sparing diuretics. Five months later, the patient discontinued acemetacin because of epigastric discomfort; at the same time, severe hypokalemia and hyperglycemia developed. Glucagon stimulation and water deprivation tests were performed. Type 2 diabetes mellitus with nephrogenic diabetes insipidus was diagnosed. To avoid further gastrointestinal complications, the patient was treated with celecoxib, a selective cyclooxygenase 2 inhibitor. This case serves as a reminder that Bartter's syndrome is associated with various metabolic derangements including nephrogenic diabetes insipidus, nephrocalcinosis and diabetes mellitus. When treating Bartter's syndrome, it is also prudent to remember that the long-term use of nonsteroidal anti-inflammatory drugs and potassium-sparing diuretics may result in serious adverse reactions.

    2013-01-01

    Type 2 autoimmune polyendocrine syndromes (APS-2) are the most frequent disorders associating several organ-specific autoimmune diseases. Their high prevalence is due to the fact that the main manifestations of APS-2, such as thyroidal autoimmunity, type 1 diabetes, autoimmune gastric atrophy and vitiligo, are common diseases. APS-2 represents a clinical model that can serve to help unravel the mechanisms underlying autoimmunity. Diagnosis of APS-2 is a challenge for the clinician, especially in poorly symptomatic forms, and may require systematic screening based on measurement of autoantibodies and functional markers.

    Full Text Available Crigler-Najjar syndrome is a rare disorder of bilirubin metabolism with two distinct forms: type 1 and type 2. We report three patients with Crigler-Najjar syndrome type 2 (CN-2. All patients had serum bilirubin values higher than 171 μmol/L and deep yellow skin color. The results of other liver function tests, glucose-6-phosphate dehydrogenase activity and hematology tests were normal, and immunologic tests for hepatitis A, B and C were negative, although one patient had slightly elevated alanine aminotransferase level (45 IU/L. Polymerase chain reaction and sequence analysis of the UDP-glucuronosyltransferase 1A1 (UGT1A1 gene revealed a novel homozygous T > A mutation at nucleotide 479 in exon 1 (Val160Glu of patient 1, a novel homozygous A >G mutation at nucleotide 610 in exon 1 (Met204Val of patient 2, and a homozygous T >G variation at nucleotide 1456 in exon 5 (Tyr486Asp plus a heterozygous G > A variation at nucleotide 211 in exon 1 (Gly71 Arg/normal of patient 3. Two of these mutations were novel and variations identified within the coding region of the UGT1A1 gene were considered the cause of CN-2 in all three patients.

    Two cases of brain stem type Neuro-Behcet's syndrome were evaluated by brain CT and Magnetic Resonance Imaging (Super-conducting type, 0.5 tesla) to correlate with the neurological findings. In the acute phase, low density area with peripheral enhancement effect and mass effect were seen at the brain stem in brain CT. MRI revealed a extensive high intensity signal area mainly involving the corticospinal tract in the meso-diencephalon as well as pons by T 2 weighted images (spin echo, TR = 1, 600 msec, TE = 90 msec) and the value of T 1 , T 2 , at the brain stem lesion were prolonged moderately. After high dose steroid treatment, the low density area in brain CT and high signal area in MRI were gradually reduced in its size. Peripheral enhancement effect in brain CT disappeared within 10 months in case 1, one month in the other case. In the chronic stage, the reduction of low density area and atrophy of brain stem were noted in brain CT. The lesion in chronic stage had low intensity in T 1 , T 2 weighted images and the T 1 , T 2 values at the lesion were mildly prolonged in MRI. Sequentially CT with enhancement and MRI examinations with T 1 , T 2 weighted images were useful to detect the lesion and to evaluate the activity, evolution of brain stem type Neuro-Behcet's syndrome.

    Absence or segmental distribution of the alpha5(IV) collagen chain along the epidermal basement membrane (EBM) is diagnostic of X-linked Alport syndrome (X-AS), but the typical morphologic alterations usually observed along the glomerular basement membrane (GBM) are lacking. However, several differences in protein composition exist between GBM and EBM, and such differences could account for a different phenotype with the same genetic defect. Type VII collagen is one of the major collagenous components of the EBM; the purpose of this study was to investigate the modifications of protein synthesis and expression of type VII collagen in the skin of patients with X-AS. The distribution of type VII collagen has been studied in 15 skin biopsies (10 from X-AS patients and 5 controls) by means of electron microscopy, immunofluorescence and confocal microscopy; type VII collagen mRNA expression was also measured by RT-PCR on the same skin fragments. Protein and mRNA amounts for type VII collagen were significantly higher in skin samples from X-AS patients than in controls (P < 0.001); highest values were in cases in which alpha5(IV) was completely absent. Our results indicate that lack of alpha5(IV) molecule significantly alters the assembly of extracellular matrix molecules other than alphax(IV) chains also at the EBM level. We suggest that the increased synthesis and deposition of type VII collagen is likely to balance the absence of stabilizing activity normally exerted by alpha5(IV).

    Waardenburg syndrome is a rare form of neurocristopathy. It is a disorder in the development of neural crest cells, caused by an altered cellular migration during the embryonic phase. That alteration causes an association of different abnormalities such as pigmentary disturbances of the hair, iris, skin, stria vascularis of the cochlea, dystopia canthorum and sensorineural hearing loss. We report a case of a 14-year-old Romanian male, with a family history of Waardenburg syndrome (mother) and Usher syndrome (father - congenitally sensorineural hearing loss and retinal degeneration). The case particularities are: the correlation between malocclusion and Waardenburg syndrome due to hypoplastic alae nasi and also factors that produced hearing loss, which could be Waardenburg syndrome, Usher syndrome or the presence of the connexin 26 (W24X) gene mutation.

    Full Text Available Mirizzi syndrome is an unusual complication of gallstone disease and occurs in approximately 1% of these pa-tients. Some cases can not be identified preoperatively; despite modern imaging techniques. Today; treatment of Mirizzi syndrome is surgical. If Mirizzi syndrome is pre-sent; the risk of bile duct injury increases; particularly during laparoscopic surgery. Therefore; preoperative or intraoperative diagnosis is important. Here; we pre-sented a 29 year-old woman with obstructive jaundice who diagnosed as cholelithiasis and choledocholithiasis. Preoperative endoscopic retrograde cholangiography re-lieved the common bile duct stone but cound not diag-nosed the Mirizzi syndrome preoperatively. During lapa-roscopy; the diagnosis of Mirizzi syndrome was sus-pected early and the procedure was converted to open cholecystectomy and T-tube to common bile duct. There was no bile duct injury and postoperative course was uneventful.

    Bartter syndrome Type III is a rare autosomal recessive disorder resulting from an inherited defect in the thick ascending limb of the loop of henle of the nephrons in kidney. The typical clinical manifestations in childhood are failure to thrive and recurrent episodes of vomiting. Typical laboratory findings which help in the diagnosis are hypokalemic metabolic alkalosis, hypomagnesemia and hypercalciuria. We report a case of Type III Bartter syndrome not responding to repeated conventional treatment of failure to thrive.

    1983-01-01

    We have measured the spectral density of the 1/f voltage noise in current-biased resistively shunted Josephson tunnel junctions and dc SQUIDs. A theory in which fluctuations in the temperature give rise to fluctuations in the critical current and hence in the voltage predicts the magnitude of the noise quite accurately for junctions with areas of about 2 x 10 4 μm 2 , but significantly overestimates the noise for junctions with areas of about 6 μm 2 . DC SQUIDs fabricated from these two types of junctions exhibit substantially more 1/f voltage noise than would be predicted from a model in which the noise arises from critical current fluctuations in the junctions. This result was confirmed by an experiment involving two different bias current and flux modulation schemes, which demonstrated that the predominant 1/f voltage noise arises not from critical current fluctuations, but from some unknown source that can be regarded as an apparent 1/f flux noise. Measurements on five different configurations of dc SQUIDs fabricated with thin-film tunnel junctions and with widely varying areas, inductances, and junction capacitances show that the spectral density of the 1/f equivalent flux noise is roughtly constant, within a factor of three of (10 -10 /f)phi 2 0 Hz -1 . It is emphasized that 1/f flux noise may not be the predominant source of 1/f noise in SQUIDS fabricated with other technologies

    Aortic dissections involving the descending aorta are a major clinical problem in patients with Marfan syndrome. The purpose of this study was to identify clinical parameters associated with type B aortic dissection and to develop a risk model to predict type B aortic dissection in patients with Marfan syndrome. Patients with the diagnosis of Marfan syndrome and magnetic resonance imaging or computed tomographic imaging of the aorta were followed for a median of 6 years for the occurrence of type B dissection or the combined end point of type B aortic dissection, distal aortic surgery, and death. A model using various clinical parameters as well as genotyping was developed to predict the risk for type B dissection in patients with Marfan syndrome. Between 1998 and 2013, 54 type B aortic dissections occurred in 600 patients with Marfan syndrome (mean age 36 ± 14 years, 52% male). Independent variables associated with type B aortic dissection were prior prophylactic aortic surgery (hazard ratio: 2.1; 95% confidence interval: 1.2 to 3.8; p = 0.010) and a proximal descending aorta diameter ≥27 mm (hazard ratio: 2.2; 95% confidence interval: 1.1 to 4.3; p = 0.020). In the risk model, the 10-year occurrence of type B aortic dissection in low-, moderate-, and high-risk patients was 6%, 19%, and 34%, respectively. Angiotensin II receptor blocker therapy was associated with fewer type B aortic dissections (hazard ratio: 0.3; 95% confidence interval: 0.1 to 0.9; p = 0.030). Patients with Marfan syndrome with prior prophylactic aortic surgery are at substantial risk for type B aortic dissection, even when the descending aorta is only slightly dilated. Angiotensin II receptor blocker therapy may be protective in the prevention of type B aortic dissections. Copyright © 2015 American College of Cardiology Foundation. Published by Elsevier Inc.

    In the 1970s, Richard Voss and John Clarke researched the actual audio physical sound of music. There are three types of noise: white noise, 1/f noise, and Brownian motion noise (1/f 2 ). 1/f noise is found to be most pleasing to human ears. White noise is too random and Brownian noise is too correlated. Similarly, for 2-dimensional sources such as graphics and images, three characteristics of monotonous, harmony and muss are also observed. The 1/f fluctuation theory provides a good way to generate affective signals both for 1-dimensional and 2-dimensional signals. This paper provides an algorithm which can generate affective patterns or graphics and obey the criteria of affective information processing

    2014-01-01

    To study dyslipidemia types in children with metabolic syndrome. From 1520 children of total population 155 children aged from 9 to 18 years were selected, who formed 2 groups: 1 group--85 children with metabolic syndrome, 2 group--54 children with normal body mass. Anthropometry, blood pressure measurement, estimation of total cholesterol, low density cholesterol, very low density cholesterol, high density cholesterol, tryglicerides in blood were done. The total cholesterol level was 1,1 times higher (p = 0.001), low density cholesterol 1,4 times higher (p = 0.001), very low density cholesterol 1,1 times higher (p= 0.015), tryglicerides 1,1 times higher (p = 0.020) in children with metabolic syndrome than in children of control group. In children with metabolic syndrome sensitively more often IIa, IV dislipidemia types and isolated hypercholesterolemia and less often IIb, III dislipidemia types and high density cholesterol isolated decrease were diagnosed. So children with metabolic syndrome were characterized by atherogenic types of dislipidemias which determine early atherosclerosis development. Children with metabolic syndrome must be examined on the lipid metabolism violation with the aim of its prevention and correction.

    Apeced syndrome is a rare disease, with autosomal recessive transmission and associated with mutations of the AIRE gene, which is involved in central and peripheral immune tolerance mechanisms. Its diagnosis is classically based on the combination of any two of the following three major criteria: chronic mucocutaneous candidiasis, hypoparathyroidism and autoimmune chronic adrenocortical insufficiency (Addison disease). One single criterion is sufficient to diagnosis a sibling of a patient already diagnosed. Because of its great phenotypic variability, some atypical or oligosymptomatic forms may not be recognized. In the presence of one of the three major criteria, it is thus important to look for other clinical manifestations--digestive, cutaneous (including keratinized appendages) and ophthalmological (until then considered minor). In these atypical forms, the diagnosis depends on molecular genetics. Prognosis is influenced by different factors that may be genetic (AIRE mutations, HLA), hormonal (sex) or environmental (infections). Potentially fatal disease (hepatitis or severe malabsorption) requires immunosuppressant therapy. Before beginning this aggressive treatment, underlying infectious foci, especially of candidiasis, must be sought and treated to prevent the development of extremely serious systemic infections in this context. A workup for splenic atrophy is also recommended.

    2015-01-01

    Autoimmune polyglandular syndromes are conditions characterized by the combination of two or more organ-specific disorders. The underestimation oftheir real frequency probable results from physicians' inadequate knowledge of these clinical entities and sometimes their atypical clinical presentation. Because they comprise a wide spectrum of autoimmune disorders, autoimmune polyglandular syndromes are divided into four types, among which type-3 is the most common one. In this article, we report the case of a young female, initially diagnosed with diabetes mellitus who several years later developed full-blown autoimmune polyglandular syndrome type 3 consisting of autoimmune thyroid disorder and latent autoimmune diabetes in adults.The discussed case suggests that in selected patients diabetes insipidus may coexist with autoimmune endocrinopathies and nonendocrine autoimmunopathies, as well as that in some patients idiopathic diabetes insipidus may be secondary to lymphocytic infiltration and destruction of the hypothalamic supraoptic and paraventricular nuclei and/or the supraoptic-hypophyseal tract

    Wolfram syndrome (WFS) is a rare autosomal recessive disease with non-autoimmune childhood onset insulin dependent diabetes and optic atrophy. WFS type 2 (WFS2) differs from WFS type 1 (WFS1) with upper intestinal ulcers, bleeding tendency and the lack ofdiabetes insipidus. Li-fespan is short due to related comorbidities. Only a few familieshave been reported with this syndrome with the CISD2 mutation. Here we report two siblings with a clinical diagnosis of WFS2, previously misdiagnosed with type 1 diabetes mellitus and diabetic retinopathy-related blindness. We report possible additional clinical and laboratory findings that have not been pre-viously reported, such as asymptomatic hypoparathyroidism, osteomalacia, growth hormone (GH) deficiency and hepatomegaly. Even though not a requirement for the diagnosis of WFS2 currently, our case series confirm hypogonadotropic hypogonadism to be also a feature of this syndrome, as reported before. © Polish Society for Pediatric Endocrinology and Diabetology.

    The Ehlers-Danlos syndromes comprise a clinically and genetically heterogeneous group of heritable connective tissue disorders, which are characterized by joint hypermobility, skin hyperextensibility, and tissue friability. In the Villefranche Nosology, six subtypes were recognized: The classical, hypermobile, vascular, kyphoscoliotic, arthrochalasis, and dermatosparaxis subtypes of EDS. Except for the hypermobile subtype, defects had been identified in fibrillar collagens or in collagen-modifying enzymes. Since 1997, a whole spectrum of novel, clinically overlapping, rare EDS-variants have been delineated and genetic defects have been identified in an array of other extracellular matrix genes. Advances in molecular testing have made it possible to now identify the causative mutation for many patients presenting these phenotypes. The aim of this literature review is to summarize the current knowledge on the rare EDS subtypes and highlight areas for future research. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available Cardiorenal Syndrome Type 1 (CRS-1 is defined as an acute worsening of heart function leading to acute kidney injury and/or dysfunction. It is an important cause of hospitalization which affects the diagnosis as well as the prognosis and treatment of patients. The purpose of this paper is to analyze causes that lead to the development of cardiorenal syndrome type 1 and its clinical consequences, as well as to emphasize the clinical importance of its early detection. The clinical studies and professional papers dealing with etiopathogenesis, diagnosis and treatment of cardiorenal syndrome type 1, have been analyzed. The most important role in the occurrence of cardio renal syndrome type 1 is played by hemodynamic mechanisms, activation of neurohumoral systems, inflammation and imbalance between the production of reactive oxygen species (ROS and nitric oxide (NO. Diagnosis of cardiorenal syndrome type 1 involves biomarkers of acute renal injury among which the most important are: neutrophil gelatinaseassociated lipocalin (NGAL, cystatin C, kidney injury molecule 1 (KIM-1, liver-type fatty acid binding protein (L-FABP, IL-18 and the values of nitrogen compounds in serum. In addition to a pharmacological therapy, various modalities of extracorporeal ultrafiltration are applied in treatment of CRS-1, particularly if there is resistance to the use of diuretic therapy. As opposed to the experimental models, in clinical practice acute renal injury is often diagnosed late so that the measures taken do not give the expected results and the protective role shown in experimental conditions do not give the same results. For all these reasons, it is necessary to analyze the pathophysiology of renal impairment in cardiorenal syndrome as well as detect early indicators of kidney injury that could have clinical benefit and positive impact on reducing the cost of treatment.

    2010-01-01

    Background: Diabetes, Hypertension, Obesity and Ischaemic Heart Disease have become a problem of public health magnitude with substantial economic burden both in the developed as well as the developing countries. Obesity is quite frequent in Type 2 diabetics and also plays a central role in causing Metabolic Syndrome (MetS). Metabolic Syndrome significantly increases the incidence of cardiovascular complications. This study was done to determine the frequency of MetS in our Type 2 diabetic patients as most of the components of MetS can be modified and identifying/managing these at an early stage might be of considerable help in reducing cardiovascular complications. Methods: This cross-sectional study was done in Medical B and Medical A wards of Ayub Teaching Hospital, Abbottabad from Nov, 08 to April, 09. Type 2 Diabetic patients aged above 40 years who gave informed consent were included in the study. Data was collected through a structured proforma. Frequency of Metabolic Syndrome was estimated according to the IDF consensus worldwide definition of the MetS. Results: Of the 100 patients enrolled in this study 56 were females and 44 were males with a mean age of 59.9 years. Out of these 100 participants seventy six (76%) were diagnosed to have metabolic syndrome. Of the 56 females, forty eight (85.71%) were having metabolic syndrome while twenty eight (63.63%) of the 44 male participants were having the syndrome. The difference was statistically significant (p<0.05). Conclusion: Frequency of MetS was found to be significantly high in this study with female preponderance. All the components, except Hypertension were more frequent in females. Diabetic patients with metabolic syndrome need more aggressive approach in management so as to decrease the incidence of cardiovascular complications. (author)

    The cardiovascular profile of postural orthostatic tachycardia syndrome + Ehlers-Danlos syndrome hypermobility type (POTS + EDSIII) has not been described, despite suggestions that it plays a role in orthostatic intolerance. We studied nine individuals diagnosed with POTS + EDSIII and found that the arterial stiffness and cardiac profiles of patients with POTS + EDSIII were comparable to those of age- and sex-matched controls, suggesting an alternate explanation for orthostatic intolerance.

    1975-11-01

    Measurements of the 1/f voltage noise in continuous metal films are reported. At room temperature, samples of pure metals and bismuth (with a carrier density smaller by 10/sup 5/) of similar volume had comparable noise. The results suggest that the noise arises from equilibrium temperature fluctuations modulating the resistance. Spatial correlation of the noise implied that the fluctuations obey a diffusion equation. The empirical inclusion of an explicit 1/f region and appropriate normalization lead to excellent agreement with the measured noise. If the fluctuations are assumed to be spatially correlated, the diffusion equation can yield an extended 1/f region in the power spectrum. The temperature response of a sample to delta and step function power inputs is shown to have the same shape as the autocorrelation function for uncorrelated and correlated temperature fluctuations, respectively. The spectrum obtained from the cosine transform of the measured step function response is in excellent agreement with the measured 1/f voltage noise spectrum. Spatially correlated equilibrium temperature fluctuations are not the dominant source of 1/f noise in semiconductors and metal films. However, the agreement between the low-frequency spectrum of fluctuations in the mean-square Johnson noise voltage and the resistance fluctuation spectrum measured in the presence of a current demonstrates that in these systems the 1/f noise is also due to equilibrium resistance fluctuations. Loudness fluctuations in music and speech and pitch fluctuations in music also show the 1/f behavior. 1/f noise sources, consequently, are demonstrated to be the natural choice for stochastic composition. 26 figures, 1 table.

    2002-10-21

    Reflex sympathetic dystrophy or complex regional pain syndrome type I is primarily a clinical diagnosis. The syndrome is most common after soft tissue damage or fractures and is more often seen in women than in men. The paramount symptom is pain, but oedema, a limited range of motion, changes in sensibility, and trophic changes are also seen. The pathogenesis is unknown, but most clinicians believe it to be caused by disturbances in the sympathetic or sensory nervous system and/or an excessive inflammatory response, most likely neurogenic inflammation. It seems that early treatment with physiotherapy and corticosteroids has a positive effect on the disease. Despite lack of documentation, the principles of treatment usually prescribed for the treatment of neurogenic pain must be taken into consideration. There is a lack of large double-blind studies on all aspects of the syndrome.

    To explore exercise beliefs and behaviours of individuals with Joint Hypermobility syndrome/Ehlers-Danlos syndrome - hypermobility type and to explore patient experiences of physiotherapy. A cross sectional questionnaire survey design was used to collect quantitative and qualitative data from adult members of the Hypermobility Syndromes Association and Ehlers-Danlos Syndrome Support UK. Descriptive and inferential statistics were used to analyse the data. Qualitative data was analysed thematically. 946 questionnaires were returned and analysed. Participants who received exercise advice from a physiotherapist were 1.75 more likely to report high volumes of weekly exercise (odds ratio [OR] = 1.75, 95% confidence interval [CI] = 1.30-2.36, p < 0.001) than those with no advice. Participants who believed that exercise is important for long-term management were 2.76 times more likely to report a high volume of weekly exercise compared to the participants who did not hold this belief (OR = 2.76, 95% CI = 1.38-5.50, p = 0.004). Three themes emerged regarding experience of physiotherapy; physiotherapist as a partner, communication - knowledge, experience and safety. Pain, fatigue and fear are common barriers to exercise. Advice from a physiotherapist and beliefs about the benefits of exercise influenced the reported exercise behaviours of individuals with Ehlers-Danlos syndrome - hypermobility type in this survey. Implications for rehabilitation Exercise is a cornerstone of treatment for Ehlers-Danlos syndrome/Ehlers-Danlos syndrome - hypermobility type. Pain, fatigue and fear of injury are frequently reported barriers to exercise. Advice from physiotherapists may significantly influence exercise behaviour. Physiotherapists with condition specific knowledge and good verbal and non-verbal communication facilitate a positive therapeutic experience.

  12. BCM1F Performance in 2012

    2013-01-01

    The Fast Beam Condition Monitor BCM1F consists of 8 single-crystal CVD 5 mm x 5 mm diamonds positioned 1.8 m on either side of the interaction point at a radius of 4.5 cm from the beam pipe. The signal is read out, shaped by a frontend ASIC, and converted to an optical signal which is then transmitted to the backend electronics in USC55. The data travels parallel paths: a discriminator path registers the time of signal pulses and transfers this information to the readout electronics, while an ADC captures full orbits for monitoring studies but is prevented from acting as data readout by a high deadtime. BCM1F provides information on the condition of the beam and ensures that the inner detector occupancy is sufficiently low for data-taking. In addition to providing beam information, BCM1F also detects collisions and as such can be used as a luminometer. Effort was made to commission BCM1F as an online luminometer in 2012. In 2012 the Real-time Histogramming Unit (RHU) for BCM1F readout was introduced. The boar...

    Full Text Available Polyglandular autoimmune syndrome is defined as multiple endocrine gland insufficiencies accompanied by autoimmune diseases of the endocrine and nonendocrine system. After Schmidt introduced a case of nontuberculosis adrenal gland dysfunction with thyroiditis in 1926, Neufeld defined polyglandular autoimmune syndrome by I, II, and III subtypes in 1980 by their presentation of occurrence age, heredity methods, relationship with human leukocyte antigen, and accompanying diseases. We report a case of a 32-year-old female with polyglandular autoimmune syndrome III accompanied by type 1 diabetes mellitus that was treated with insulin (36 units per day for 11 years. She had insulin deficiency and Hashimoto thyroiditis as an autoimmune disorder. In addition, she had several features similar to Albright's hereditary osteodystrophy including short stature, truncal obesity, round face, short neck, low intelligence (full IQ 84, and decreased memory. Although Albright's hereditary osteodystrophy is morphological evidence of pseudohypoparathyroidism or pseudopseudohypoparathyroidism, she had primary hypoparathyroidism on laboratory results. Here, we report a case of polyglandular autoimmune syndrome III with type 1 diabetes mellitus, autoimmune thyroiditis, and primary hypoparathyroidism, accompanied by clinical features similar to Albright's hereditary osteodystrophy.

    Full Text Available Bartter syndrome (BS type 1 (OMIM #601678 is a hereditary salt-losing renal tubular disorder characterized by hypokalemic metabolic alkalosis, hypercalciuria, nephrocalcinosis, polyuria, recurrent vomiting, and growth retardation. It is caused by loss-of-function mutations of the SLC12A1 gene, encoding the furosemide-sensitive Na-K-Cl cotransporter. Recently, a phenotypic variability has been observed in patients with genetically determined BS, including absence of nephrocalcinosis, hypokalemia, and/or metabolic alkalosis in the first year of life as well as persistent metabolic acidosis mimicking distal renal tubular acidosis. We report the case of a child with a genetically determined diagnosis of Bartter syndrome type 1 who presented with a phenotype of nephrogenic diabetes insipidus, with severe hypernatremia and urinary concentrating defect. In these atypical cases, molecular analysis is mandatory to define the diagnosis, in order to establish the correct clinical and therapeutic management.

    To assess the prevalence, severity and impact of fatigue on individuals with joint hypermobility syndrome (JHS)/Ehlers-Danlos syndrome - hypermobility type (EDS-HT) and establish potential determinants of fatigue severity in this population. Questionnaires on symptoms and signs related to fatigue, quality of life, mental health, physical activity participation and sleep quality were completed by people with JHS/EDS-HT recruited through two social media sites. Multiple regression analysis was performed to identify predictors of fatigue in this population. Significant fatigue was reported by 79.5% of the 117 participants. Multiple regression analysis identified five predictors of fatigue severity, four being potentially modifiable, accounting for 52.3% of the variance in reported fatigue scores. Predictors of fatigue severity were: the self-perceived extent of joint hypermobility, orthostatic dizziness related to heat and exercise, levels of participation in personal relationships and community, current levels of physical activity and dissatisfaction with the diagnostic process and management options provided for their condition. Fatigue is a significant symptom associated with JHS/EDS-HT. Assessment of individuals with this condition should include measures of fatigue severity to enable targeted management of potentially modifiable factors associated with fatigue severity. Implications for rehabilitation Fatigue is a significant symptom reported by individuals affected by joint hypermobility syndrome/Ehlers-Danlos syndrome - hypermobility type. Potentially modifiable features that contribute to fatigue severity in this population have been identified. Targeted management of these features may decrease the severity and impact of fatigue in joint hypermobility syndrome/Ehlers-Danlos syndrome - hypermobility type.

    The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue. It has been described largely in those with musculoskeletal complaints including joint hypermobility, joint subluxations/dislocations, as well as skin and soft tissue manifestations. Many patients report activity-related pain and some go on to have daily pain. Two undifferentiated syndromes have been used to describe these manifestations-joint hypermobility syndrome and hEDS. Both are clinical diagnoses in the absence of other causation. Current medical literature further complicates differentiation and describes multiple associated symptoms and disorders. The current EDS nosology combines these two entities into the hypermobile type of EDS. Herein, we review and summarize the literature as a better clinical description of this type of connective tissue disorder. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    2015-01-01

    Graphene nanopores are receiving great attention due to their atomically thin membranes and intrinsic electrical properties that appear greatly beneficial for biosensing and DNA sequencing. Here, we present an extensive study of the low-frequency 1/f noise in the ionic current through graphene nanopores and compare it to noise levels in silicon nitride pore currents. We find that the 1/f noise magnitude is very high for graphene nanopores: typically two orders of magnitude higher than for silicon nitride pores. This is a drawback as it significantly lowers the signal-to-noise ratio in DNA translocation experiments. We evaluate possible explanations for these exceptionally high noise levels in graphene pores. From examining the noise for pores of different diameters and at various salt concentrations, we find that in contrast to silicon nitride pores, the 1/f noise in graphene pores does not follow Hooge’s relation. In addition, from studying the dependence on the buffer pH, we show that the increased noise cannot be explained by charge fluctuations of chemical groups on the pore rim. Finally, we compare single and bilayer graphene to few-layer and multi-layer graphene and boron nitride (h-BN), and we find that the noise reduces with layer thickness for both materials, which suggests that mechanical fluctuations may be the underlying cause of the high 1/f noise levels in monolayer graphene nanopore devices.

    Full Text Available Joint hypermobility syndrome (JHS and Ehlers-Danlos syndrome, hypermobility type (EDS-HT are two clinically overlapping heritable connective tissue disorders strongly associating with pain, fatigue and other secondary aspects. No specific treatment exist for this syndrome and rehabilitation play a role in the management of these patients. The aim of this paper is to evaluate what are the evidence in literature about rehabilitation. Research was done using database PUBMED and consist in a revision of the studies published in the last 15 years. All studies agree to the beneficial role of the rehabilitative treatment and physical therapy but it’s necessary to add more further studies to establish a high quality, evidence-based physical therapy for this specific population.

    To study Chinese syndrome typing of acute hepatic failure (AHF) mice model by screening effective formulae. Lipoplysaccharides (LPS)/D-galactosamine (D-GaIN) was intraperitoneally injected to mice to establish the AHF mice model. Yinchenhao Decoction, Huanglian Jiedu Decoction, Buzhong Yiqi Decoction, and Xijiao Dihuang Decoction were administered to model mice respectively by gastrogavage. The behavior and the survival rate were monitored. The liver function and pathological changes of liver tissues were detected. In all the tested classic recipes, the survival rate was elevated from 10% to 60% by administration of Xijiao Dihuang Decoction. Five h after modeling, the serum alanine aminotransferase (ALT) level was (183.95 +/- 52.00) U/L, and aspartate aminotransferase (AST) (235.70 +/- 34.03) U/L in Xijiao Di-huang Decoction Group, lower than those of the model control group, but with insignificant difference (ALT: 213.32 +/- 71.93 U/L; AST: 299.48 +/- 70.56 U/L, both P > 0.05). Xijiao Dihuang Decoction could obviously alleviate the liver injury. Xijiao Dihuang Decoction was an effective formula for LPS/D-GaIN induced AHF model. According to syndrome typing through formula effect, heat toxin and blood stasis syndrome dominated in the LPS/D-GalN induced AHF mice model.

    Complex regional pain syndrome type 1 (CRPS-1) was identified in the Netherlands more than 30 years ago, but since then the arguments supporting this diagnosis have become weaker. Incidence has decreased, it is often not possible to make a definite diagnosis, the pathophysiology remains unclear and treatments are extremely diverse. Since the patient group is so heterogeneous, it is often unclear exactly which patients should be included. Disuse due to immobilization can give an identical clinical picture, including the inflammatory parameters that are seen in CRPS-1. CRPS-1 following injury can be prevented with exercise, and incidence is declining dramatically. Taking these factors into consideration, we support the view that CRPS-1 is not an illness but rather a 'disuse syndrome' as a result of immobilization, or there may be a missed underlying diagnosis.

    Full Text Available Estimated incidence of Crigler-Najjar syndrome(CNS is 1 case per 1,000,000 births(1 million. The overall prevalence of CN syndrome is unknown, with only several hundred people reported to have this disease. It is interestingly very rare to encounter a pregnant adult women with congenital jaundice. Pregnancy in CN type II patients is a diagnostic and a therapeutic challenge because of the high risk of bilirubin encephalopathy with serious neurological damage as life-threatening complications for the fetus. To date 8 pregnancy outcome have been reported from 5 women and we report the6 woman with a successful 9 th pregnancy outcome. We have discussed detail history, presentation and management during pregnancy and care of the new born.

    Full Text Available A 70-year-old woman presented with burning pain and swelling over dorsum of right hand and small joints of the fingers, associated with redness, feeling of warmth, and stiffness of the fingers, with inability to bend the fingers since 2 months. The symptoms were progressively increasing in intensity for the past 1 month. There was no history of fever or trauma to the hand. Two months before her symptoms started, she had permanent pacemaker implanted for complete heart block with syncope. She was hypertensive and was on regular medication. Her X-ray of right hand showed decreased bone density (demineralisation, suggestive of osteopenia. A diagnosis of reflex sympathetic dystrophy syndrome or complex regional pain syndrome type I induced by pacemaker insertion was made. She was treated with amitriptyline and steroids, after which her symptoms improved dramatically.

    Auto-regressive conditionally heteroskedastic (ARCH) family models are still used, by practitioners in business and economic policy making, as a conditional volatility forecasting models. Furthermore ARCH models still are attracting an interest of the researchers. In this contribution we consider the well known GARCH(1,1) process and its nonlinear modifications, reminiscent of NGARCH model. We investigate the possibility to reproduce power law statistics, probability density function and power spectral density, using ARCH family models. For this purpose we derive stochastic differential equations from the GARCH processes in consideration. We find the obtained equations to be similar to a general class of stochastic differential equations known to reproduce power law statistics. We show that linear GARCH(1,1) process has power law distribution, but its power spectral density is Brownian noise-like. However, the nonlinear modifications exhibit both power law distribution and power spectral density of the 1 /fβ form, including 1 / f noise.

    Full Text Available Background. The orofaciodigital syndromes (OFDS are a heterogeneous group of syndromes that affect the face, oral cavity, and the digits. OFDS type IV (OMIM %258860 is rare and characterized by broad nasal root and tip, orbital hypertelorism or telecanthus, micrognathia, hypoplastic mandible, and low-set ears. Oral symptoms may include cleft lip, cleft or highly arched palate, bifid uvula, cleft or hypoplastic maxillary and mandibular alveolar ridge, oral frenula, lingual hamartoma, and absent or hypoplastic epiglottis. Dental anomalies are common and generally include disturbances in the number of teeth. Case Report. This report presents a six-year-old girl, referred with the chief complaint of missing teeth. She was diagnosed as having OFDS type IV based on clinical findings. Her parents reported three deceased children and two fetuses that had the same phenotype. She was the seventh child of consanguineous parents who were first cousins. Conclusion. This is a very rare syndrome. Many reported OFDS type IV cases have consanguineous parents, consistent with an autosomal recessive trait. Manifestation of cleft palate in the healthy sibling may be mild expression of the disorder or an unrelated isolated cleft.

    Full Text Available Griscelli syndrome (GS is a rare autosomal recessive genetic disorder characterized by variable immunodeficiency, partial albinism, abnormal accumulation of melanosomes in melanocytes, pigmentary dilution of the skin, and shiny silver-gray hair. GS has three types, with the first and second types caused by mutations in two genes being located at band 15q21: RAB27A and MYO5A. The expression of the third form of GS is restricted to the characteristic hypopigmentation of GS, and results from mutation in the gene that encodes melanophilin MLPH. It has also been shown that an identical phenotype can result from the deletion of the MYO5A F-exon. The aim of this case report is the presentation of oral and dental features and SEM images of the hair of a 12-year-old girl with GS type 3. [Arch Clin Exp Surg 2015; 4(3.000: 164-167

    To describe the multi-channel cochlear implantation in patients with Waardenburg syndrome including surgeries, pre and postoperative hearing assessments as well as outcomes of speech recognition. Multi-channel cochlear implantation surgeries have been performed in 12 cases with Waardenburg syndrome type II in our department from 2000 to 2008. All the patients received multi-channel cochlear implantation through transmastoid facial recess approach. The postoperative outcomes of 12 cases were compared with 12 cases with no inner ear malformation as a control group. The electrodes were totally inserted into the cochlear successfully, there was no facial paralysis and cerebrospinal fluid leakage occurred after operation. The hearing threshold in this series were similar to that of the normal cochlear implantation. After more than half a year of speech rehabilitation, the abilities of speech discrimination and spoken language of all the patients were improved compared with that of preoperation. Multi-channel cochlear implantation could be performed in the cases with Waardenburg syndrome, preoperative hearing and images assessments should be done.

    Glucose is the brain's main source of energy. To pass the blood-brain barrier, glucose transporter protein type 1 (GLUT-1) is essential. Mutations in the SLC2A1 gene which codes for GLUT-1 may therefore compromise the supply of glucose to the brain. The aim of this review is to describe the clinical consequences of such mutations, with special emphasis on GLUT-1 encephalopathy. This review is based on a non-systematic literature search in PubMed and the authors' experience within the field. Epileptic or epilepsy-like are usually the first symptom in children with the GLUT-1 deficiency syndrome. Later on these children suffer delayed psychomotor development, microcephaly, ataxia, spasticity or movement disorders. EEG abnormalities may develop. GLUT-1 deficiency syndrome should be suspected in children with epilepsy-like seizures and delayed development combined with a low content of glucose in spinal fluid. The diagnosis is confirmed by genetic testing. Treatment is a ketogenic diet, as ketone bodies pass the blood-brain barrier using other transport proteins than GLUT-1. GLUT-1-deficiency syndrome is a rare metabolic encephalopathy which is not well known and probably underdiagnosed. An early diagnosis and early start of a ketogenic diet may give these children a normal or nearly normal life.

    Seventeen obligate carriers from nine families with autosomal recessive Usher syndrome type I underwent otological, audiological, vestibular, and ophthalmological examination in order to identify possible manifestations of heterozygosity. Linkage studies were performed and six families showed linkage to chromosome region 11q13.5 while 3 families have so far failed to show linkage to the candidate regions. Eight obligate carriers had an abnormal puretone audiogram. Two different audiometric patterns could be distinguished when hearing loss was corrected for age and sex. Four carriers (24%) had significant sensorineural hearing loss (SNHL) which increased at higher frequencies. The other 13 carriers had SNHL of about 10 dB at 0.25 and 0.5 kHz, but less at higher frequencies. Vestibular findings were generally normal. Electrooculography demonstrated a significant lower mean light peak/dark trough ratio in Usher type I carriers compared to normal control individuals. The methods used in this study were found not to be specific enough to clinically identify carriers of Usher type I syndrome. Nevertheless it is remarkable that a number of obligate carriers showed significant audiological and ophthalmological abnormalities. 29 refs., 1 fig., 3 tabs.

  13. Type 1 diabetes and polyglandular autoimmune syndrome: A review

    Hansen, Martin P; Matheis, Nina; Kahaly, George J

    2015-01-01

    Type 1 diabetes (T1D) is an autoimmune disorder caused by inflammatory destruction of the pancreatic tissue. The etiopathogenesis and characteristics of the pathologic process of pancreatic destruction are well described. In addition, the putative susceptibility genes for T1D as a monoglandular disease and the relation to polyglandular autoimmune syndrome (PAS) have also been well explored. The incidence of T1D has steadily increased in most parts of the world, especially in industrialized nations. T1D is frequently associated with autoimmune endocrine and non-endocrine diseases and patients with T1D are at a higher risk for developing several glandular autoimmune diseases. Familial clustering is observed, which suggests that there is a genetic predisposition. Various hypotheses pertaining to viral- and bacterial-induced pancreatic autoimmunity have been proposed, however a definitive delineation of the autoimmune pathomechanism is still lacking. In patients with PAS, pancreatic and endocrine autoantigens either colocalize on one antigen-presenting cell or are expressed on two/various target cells sharing a common amino acid, which facilitates binding to and activation of T cells. The most prevalent PAS phenotype is the adult type 3 variant or PAS type III, which encompasses T1D and autoimmune thyroid disease. This review discusses the findings of recent studies showing noticeable differences in the genetic background and clinical phenotype of T1D either as an isolated autoimmune endocrinopathy or within the scope of polyglandular autoimmune syndrome.

    Background: Metabolic syndrome (MetS) is a cluster of coronary risk factors such as diabetes and pre-diabetes, abdominal obesity, high triglyceride (TG), low high density lipoprotein cholesterol (HDL-c) levels and high blood pressure (BP). It is estimated that around a quarter of the world adult population have MetS and they are twice as likely to die from it and three times as likely to have a coronary event or stroke compared with people without the syndrome. Methods: This observational descriptive study was conducted at the Department of General Medicine, Federal Government Polyclinic Islamabad. All type-2 diabetics presenting in the outpatient and inpatient department during 11 months between the ages of 30-80 were enrolled. They were interviewed, blood pressure, waist circumference, fasting blood glucose, and lipid profiles were checked. Results: Of the 300 patients 165 (55 percentage) were females and 135 (45 percentage) were males with mean age 52.47±11.24 years. The mean duration of Diabetes Mellitus was 7.38±3.85 years. Metabolic Syndrome was present in 83 percentage of the study population, 129 (43 percentage) were male and 171 (57 percentage) were female. The p-value was statistically significant on comparing the presence of the Metabolic Syndrome with waist circumference, serum triglyceride levels, and blood pressure as it was <0.05. The most commonly occurring finding was a decreased HDL-cholesterol in both genders. Conclusions: The MetS was present in 83 percentage of the diabetic population, mostly in females with decreased HDL-cholesterol being the most common in both genders. (author)

  17. ''1/f noise'' in music: Music from 1/f noise

    1978-01-01

    The spectral density of fluctuations in the audio power of many musical selections and of English speech varies approximately as 1/f (f is the frequency) down to a frequency of 5 x 10/sup -4/ Hz. This result implies that the audio-power fluctuations are correlated over all times in the same manner as ''1/f noise'' in electronic components. The frequency fluctuations of music also have a 1/f spectral density at frequencies down to the inverse of the length of the piece of music. The frequency fluctuations of English speech have a quite different behavior, with a single characteristic time of about 0.1 s, the average length of a syllable. The observations on music suggest that 1/f noise is a good choice for stochastic composition. Compositions in which the frequency and duration of each note were determined by 1/f noise sources sounded pleasing. Those generated by white-noise sources sounded too random, while those generated by 1/f/sup 2/ noise sounded too correlated.

    Joint Hypermobility Syndrome, also known as Ehlers-Danlos Syndrome Hypermobility Type (JHS/EDS-HT), is a heritable disorder of connective tissue, common but poorly known by the medical community. Although generalized joint hypermobility and fragility of tissues have been described as core features, recent research highlights the multisystemic nature of JHS/EDS-HT, which presents with a wide range of articular and extra-articular symptoms. Among these, gastrointestinal problems, temporomandibular disorders, and smell and taste abnormalities are common among those affected, having significant implications for eating. The present work reviews the literature linking JHS/EDS-HT and eating problems. Two illustrative case reports, in which JHS/EDS-HT manifestations contribute to developing and maintaining disturbed eating behaviors and significant weight loss, are presented.

A descriptive study. Department of Orthopedic Surgery and Traumatology Unit-I (DOST-I), Mayo Hospital, Lahore, between November 2013 to June 2014. All patients presented in OPD with shoulder pain were included as subjects and evaluated by clinical test and categorised using X-ray scapula Y-view. Patients with impingement syndrome were correlated with Bigliani types and offered intra-lesional injection into sub-acromial space with 2ml of xylocaine 2% and 40 mg of methylprednisolone using 22 gauge needle. The effectiveness was assessed in terms of relieving pain and good functional outcomes; and rotator cuff tear was clinically assessed among impingement positive patient. The pain was assessed using visual analogue score before and after the administration of the injection. Demographic variables for frequencies and their associations were analysed using SPSS version 20.0. Significance level was p shoulder impingement. Most had moderate pain. Thirty-four patients required intralesional steroid, which relieved the pain in 31 of them. Shoulder impingement syndrome without tear of rotator cuff tendon was found in younger age group between 40 to 45 years, which was relieved by intralesional corticosteroid administration. These patients had type II (curved) acromion, according to Bigliani classification.

    This study presents a case of an 8-year-old boy with iris heterochromia and anisometropic amblyopia who was diagnosed with Waardenburg syndrome (WS) type 2. An ophthalmic examination revealed iris heterochromia and anisometropic amblyopia in our patient. In the systemic examination, a white forelock and vitiligo on the arms and body were observed and neurosensory hearing loss was revealed, for which the patient used hearing aids. Identification and typing of patients with WS is crucial to address neurosensory hearing loss, glaucoma and fundus changes. While it might be challenging to communicate with a patient with speech and hearing problems, visual acuity should be examined carefully and probable amblyopia should be identified. Anterior segment changes and signs of glaucoma should also be evaluated in detail.

    The purpose of this study was to identify the genetic causes of a family presenting with multiple symptoms overlapping Usher syndrome type II (USH2) and Waardenburg syndrome type IV (WS4). Targeted next-generation sequencing including the exon and flanking intron sequences of 79 deafness genes was performed on the proband. Co-segregation of the disease phenotype and the detected variants were confirmed in all family members by PCR amplification and Sanger sequencing. The affected members of this family had two different recessive disorders, USH2 and WS4. By targeted next-generation sequencing, we identified that USH2 was caused by a novel missense mutation, p.V4907D in GPR98; whereas WS4 due to p.V185M in EDNRB. This is the first report of homozygous p.V185M mutation in EDNRB in patient with WS4. This study reported a Chinese family with multiple independent and overlapping phenotypes. In condition, molecular level analysis was efficient to identify the causative variant p.V4907D in GPR98 and p.V185M in EDNRB, also was helpful to confirm the clinical diagnosis of USH2 and WS4.

When GJH is accompanied by pain in ≥4 joints over a period ≥3 months in the absence of other conditions that cause chronic pain, the hypermobility syndrome (HMS may be diagnosed. In addition, GJH is also a clinical sign that is frequently present in hereditary diseases of the connective tissue, such as the Marfan syndrome, osteogenesis imperfecta, and the Ehlers–Danlos syndrome. However, within the Ehlers–Danlos spectrum, a similar subcategory of patients having similar clinical features as HMS but lacking a specific genetic profile was identified: Ehlers–Danlos syndrome hypermobility type (EDS-HT. Researchers and clinicians have struggled for decades with the highly diverse clinical presentation within the HMS and EDS-HT phenotypes (Challenge 1 and the lack of understanding of the pathological mechanisms that underlie the development of pain and its persistence (Challenge 2. In addition, within the HMS/EDS-HT phenotype, there is a high prevalence of psychosocial factors, which again presents a difficult issue that needs to be addressed (Challenge 3. Despite recent scientific advances, many obstacles for clinical care and research still remain. To gain further insight into the phenotype of HMS/EDS-HT and its mechanisms, clearer descriptions of these populations should be made available. Future research and clinical care should revise and create consensus on the

    Full Text Available Long QT syndrome type 1 (LQT1 is a subtype of a congenital cardiac syndrome caused by mutation in the KCNQ1 gene, which encodes the α-subunit of the slow component of delayed rectifier K+ current (IKs channel. Arrhythmias in LQT1 are characterized by prolongation of the QT interval on ECG, as well as the occurrence of life-threatening cardiac events, frequently triggered by adrenergic stimuli (e.g., physical or emotional stress. During the past two decades, much advancement has been made in understanding the molecular pathogenesis underlying LQT1. Uncovering the genotype-phenotype correlations in LQT1 is of clinical importance to better understand the gene-specific differences that may influence the propensity for developing life-threatening arrhythmias under specific conditions. Elucidation of these mechanisms will also help to improve the diagnosis and management of this cardiac disorder based on gene-specific considerations. This review describes the current medical consensus and recent developments regarding the molecular pathogenesis of LQT1 and provides a novel insight into the adrenergic regulation of this disease.

    Full Text Available Ehlers-Danlos syndrome (EDS is a heterogeneous group of heritable connective tissue disorders whose primary clinical features include soft and extensible skin, articular hypermobility and tissue fragility. EDS type VIIC or ‘human dermatosparaxis’ is an autosomal recessive disease characterized by severe skin fragility and sagging redundant skin (major criteria with a soft, doughy texture, easy bruising, premature rupture of fetal membranes and large hernias (minor criteria. Dermatosparaxis (meaning ‘tearing of skin’, which has been described in several non-human species, is a disorder of the connective tissue resulting from a deficiency of the enzyme that cleaves the registration peptide off the N-terminal end of collagen after it has been secreted from fibroblasts. We describe a Mexican case from consanguineous parents with all the phenotypical characteristics previously described, plus skeletal abnormalities.

    Full Text Available Abstract Background Elevated serum uric acid levels (SUA have been associated with an increased risk of cardiovascular diseases and the metabolic syndrome (MetS and are often reported to be higher in females than in males. The aim of this report is to determine the prevalence and clinical correlates of hyperuricaemia and also to evaluate associations with the MetS in people with type 2 diabetes mellitus (DM. Methods This was a cross-sectional study conducted in people with type 2 DM in Lagos, Nigeria. Hyperuricaemia was defined by cut-off values of > 7 mg/dl for men and > 6 mg/dl for women. The diagnosis of MetS was made using the new definition by the American Heart Association and other related bodies. Clinical and biochemical parameters were compared between subjects with hyperuricaemia and normouricaemia. Statistical analysis included usage of Student's t test, Pearson correlation coefficients, multivariate regression analysis and chi square. Results 601 patients with type 2 DM aged between 34-91 years were recruited for the study. The prevalence rates of hyperuricaemia and the MetS were 25% and 60% respectively. The frequency of occurrence of hyperuricaemia was comparable in both genders (59% vs 41%, p = 0.3. Although, the prevalence of the MetS in subjects with hyperuricaemia and normouricaemia was comparable (61 vs 56%, p = 0.1, a higher proportion of hyperuricaemic subjects had 3 or more components of the Mets compared with normouricaemic subjects. Possible predictors of hyperuricaemia include central obesity, smoking and elevated serum triglycerides (TG. SUA levels were found to be positively and significantly associated with serum TG (r = 0.2, p = 0.0001 and total cholesterol (r = 13, p = 0.001. Conclusion The prevalence of hyperuricaemia in subjects with type 2 DM is comparable in both genders and possible predictors of hyperuricaemia are potentially modifiable. SUA is positively and significantly associated with serum TG and total

    Hematopoietic cell transplantation is a life-saving procedure, but one associated with increasing long-term cardiovascular risk requiring frequent long-term follow-up. This therapy has significantly lengthened survival in mucopolysaccharidosis type IH (Hurler syndrome), a disease with known coronary artery involvement. Metabolic syndrome-a constellation of central obesity, high blood pressure, low high-density lipoprotein cholesterol, elevated triglycerides, and fasting blood glucose-is associated with increased cardiovascular risk, and occurs when any 3 or more of these 5 components is present within a single individual. The incidence of metabolic syndrome and its components is poorly defined after transplantation for Hurler syndrome. Chart review of all long-term survivors of hematopoietic cell transplantation for Hurler syndrome ≥9 years of age for factors comprising the metabolic syndrome: obesity, high blood pressure, low high-density lipoprotein cholesterol, elevated triglycerides, and fasting blood glucose. Sixty-three patients were evaluated, 20 of whom had components of the metabolic syndrome available for review. There was no significant difference in age at transplantation, sex, number of transplants, pretransplant radiation, or percent engraftment between those with and without these data. Median follow-up after transplantation for the 20 patients with data was 14.3 years. Only 1 (5%) patient of this group fulfilled the criteria for metabolic syndrome. Fifty-three percent of the patients had 1 or more components of metabolic syndrome: the most common was high blood pressure occurring in 40%. Metabolic syndrome is uncommon in this cohort of long-term survivors of hematopoietic cell transplantation for Hurler syndrome but almost half of the patients had 1 or more components of the syndrome, with high blood pressure being the most common. Further studies are needed to develop guidelines in this diagnosis as well as other nonmalignant diseases of children

    2003-01-01

    Full Text Available The treatment of patients with complex regional pain syndrome (CRPS type 1 is challenging and unpredictable as the condition presents with vascular and neuropathic symptoms after nil or even minor injury to a peripheral nerve. The condition is one of a pain and motor dysfunction. The pathophysiology is not well understood and the relief of symptoms may change from being sympathetically mediated to sympathetically independent during  the course of the disease. At any stage physiotherapy has been advocated as the corner stone and most important aspect of treatment in the rehabilitation of these individuals but unfortunately it has been difficult to execute when pain is exacerbated due to allodynia (unbearable to touch or move and hyperalgesia. Best results have been obtained if the patients are recognised and treated in the early or acute phase and it has been found that through careful assessment and analysis these patients can be recognised by previous events that have occurred in their initial case history. The treatment in the acute stage with physiotherapy modalities such as electrical stimulation and acupuncture will produce an early cessation of the symptoms and prevention of the disease developing into the fully blown CRPS type 1 with irreversible and possibly atrophic consequences. Case histories have been presented that illustrate these important aspects and demonstrate  the value of early and the appropriate physiotherapy that may be more successful than other pharmacological and physical interventions in this disease.

    Full Text Available Complex regional pain syndrome (CPRS, type 1 is a pain disorder that develops unpredictably and can follow a minor injury. A 12-year-old boy presented with severe pain in the feet and could not walk or stand weight bearing. Normal X-rays showed osteopenic changes and radiolucent lines, which appeared to be stress fractures. Three-phase bone scintigraphy showed no uptake in the left lower leg on the blood pool phase or on the immediate or delayed images. This indicated typical CPRS type 1 in children. The uptake in the right foot was increased and the stress fracture and other illness could not be differentiated. Computed tomography was done to exclude stress fractures. Only osteopenic changes in both calcaneus bones were found and there was no evidence of cortical stress fractures. Magnetic resonance images revealed oedema in the calcaneus and talus bones of both feet. The patient received epidural narcotic infusion with sympathetic blockage for 1 week combined with extensive physiotherapy. The blood pool phase of the bone scan became normal within 2 weeks, and increased uptake in both feet was noticed. The patient was followed up with MRI every 3 months and the bone marrow oedema disappeared after 6 months.

    Gastrointestinal involvement is a well known complication of Ehlers-Danlos syndromes (EDSs), mainly in form of abdominal emergencies due to intestinal/abdominal vessels rupture in vascular EDS. In the last decade, a growing number of works investigated the relationship between a wide spectrum of chronic gastrointestinal complaints and various EDS forms, among which the hypermobility type (a.k.a. joint hypermobility syndrome; JHS/EDS-HT) was the most studied. The emerging findings depict a major role for gastrointestinal involvement in the health status and, consequently, management of JHS/EDS-HT patients. Nevertheless, fragmentation of knowledge limits its impact on practice within the boundaries of highly specialized clinics. In this paper, literature review on gastrointestinal manifestations in JHS/EDS-HT was carried out and identified papers categorized as (i) case-control/cohort studies associating (apparently non-syndromic) joint hypermobility and gastrointestinal involvement, (ii) case-control/cohort studies associating JHS/EDS-HT and gastrointestinal involvement, (iii) case reports/series on various gastrointestinal complications in (presumed) JHS/EDS-HT, and (iv) studies reporting gastrointestinal features in heterogeneous EDS patients' cohorts. Gastrointestinal manifestations of JHS/EDS-HT were organized and discussed in two categories, including structural anomalies (i.e., abdominal/diaphragmatic hernias, internal organ/pelvic prolapses, intestinal intussusceptions) and functional features (i.e., dysphagia, gastro-esophageal reflux, dyspepsia, recurrent abdominal pain, constipation/diarrhea), with emphasis on practice and future implications. In the second part of this paper, a summary of possible nutritional interventions in JHS/EDS-HT was presented. Supplementation strategies were borrowed from data available for general population with minor modifications in the light of recent discoveries in the pathogenesis of selected JHS/EDS-HT features. © 2015

  17. Rules for distinguishing toxicants that cause type I and type II narcosis syndromes.

    Narcosis is a nonspecific reversible state of arrested activity of protoplasmic structures caused by a wide variety of organic chemicals. The vast majority of industrial organic chemicals can be characterized by a baseline structure-toxicity relationship as developed for diverse aquatic organisms, using only the n-octanol/water partition coefficient as a descriptor. There are, however, many apparent narcotic chemicals that are more toxic than baseline narcosis predicts. Some of these chemicals have been distinguished as polar narcotics. Joint toxic theory and isobole diagrams were used to show that chemicals strictly additive with phenol were generally more toxic than predicted by narcosis I models and characterized by a different mode of action called narcosis II syndrome. This type of toxicity is exemplified by certain amides, amines, phenols, and nitrogen heterocycles. Evidence is provided that suggests that narcosis II syndrome may result from the presence of a strong hydrogen bonding group on the molecule, and narcosis I syndrome results from hydrophobic bonding of the chemical to enzymes and/or membranes. This shift in toxic action is apparently indistinguishable for narcotic chemicals with log P greater than about 2.7. General rules for selecting the appropriate models are proposed. PMID:2269227

    Usher syndrome type 1 (US1) is an autosomal recessive disease characterized by profound congenital hearing impairment with unintelligible speech, early retinitis pigmentosa, and constant vestibular dysfunction. Three localizations have been described in US1: USH1A, 14q32; USH1B, 11q13.5; and USH1C, 11p15. Studying a series of 33 affected individuals belonging to 20 US1 pedigrees of French ancestry, the authors found that none of the three localizations accounted for all US1 families in the series. However, when the sample was split into two groups according to the geographic origin of the probands' grandparents, they were able to confirm the presence of a gene for US1 on chromosome 14q32 (USH1A) in 9 families originating from the Poitou region in Western France. Moreover, they refined the genetic mapping of USH1A by showing that the disease gene maps to the D14S13 locus, within the genetic interval defined by loci D14S78 and D14S250 (location score in log base 10 = 4.90). Consistent with this, nonsignificant lod score values for linkage to either USH1B or USH1C were found in this group. With regard to US1 families of other geographic origin (Normandy and Northern France, 11 families), nonsignificant lod scores for linkage to chromosome 11q13.5 were observed. However, the HOMOG test suggested that USH1B might account for the disease in 9/11 families in the series (families 10-19), the latter two families possibly being accounted for by USH1C (maximum likelihood for heterogeneity = 7.91 in lnL; heterogeneity versus homogeneity, P = 0.01; heterogeneity versus nonlinkage, P < 0.01). The present study supports the view that Usher syndrome type 1 is a genetically heterogeneous condition that is caused by at least three genes and possibly many more. 16 refs., 4 figs., 3 tabs.

    Presented are 2 patients with abnormal craniofacial region, limbs, and abdomen, features that may be consistent with Pfeiffer syndrome, type 3. Both patients had bicoronal and bisphenoidal synostosis, extreme exophthalmic midface hypoplasia, and hydrocephalus. The limbs had a fixed flexion deformity of the elbows with broad thumbs which were radiopalmarly deviated; the toes were broad with a varus deformity and syndactyly toes 2-5. Both patients developed bowel obstruction secondary to midgut malrotation, and one of the patients had prune belly syndrome. Review of the literature disclosed an additional patient who, in retrospect, had Pfeiffer syndrome type 3 and midgut malrotation. These patients suggest that intestinal malrotation with or without prune belly syndrome may be a common component of this entity.

    The human deafness-pigmentation syndromes, Waardenburg syndrome (WS) type 2a, and Tietz syndrome are characterized by profound deafness but only partial cutaneous pigmentary abnormalities. Both syndromes are caused by mutations in MITF. To illuminate differences between cutaneous and otic melanocytes in these syndromes, their development and survival in heterozygous Microphthalmia-White (Mitf(Mi-wh) /+) mice were studied and hearing function of these mice characterized. Mitf(Mi-wh) /+ mice have a profound hearing deficit, characterized by elevated auditory brainstem response thresholds, reduced distortion product otoacoustic emissions, absent endocochlear potential, loss of outer hair cells, and stria vascularis abnormalities. Mitf(Mi-wh) /+ embryos have fewer melanoblasts during embryonic development than their wild-type littermates. Although cochlear melanocytes are present at birth, they disappear from the Mitf(Mi-wh) /+ cochlea between P1 and P7. These findings may provide insight into the mechanism of melanocyte and hearing loss in human deafness-pigmentation syndromes such as WS and Tietz syndrome and illustrate differences between otic and follicular melanocytes. © 2012 John Wiley & Sons A/S.

    We report a patient with cat eye syndrome and interrupted aortic arch type B, a typical finding in the 22q11.2 deletion syndrome. Chromosomal analysis and fluorescent in situ hybridization (FISH) showed a supernumerary bisatellited isodicentric marker chromosome derived from chromosome 22. The segment from 22pter to 22q11.2 in the supernumerary chromosome found in our patient does not overlap with the region deleted in patients with the 22q11.2 deletion syndrome. However, the finding of an interrupted aortic arch type B is unusual in CES, although it is a frequent heart defect in the 22q11 deletion syndrome.

    Individuals with Hermansky-Pudlak syndrome type 1 (HPS-1), an autosomal recessive disorder characterized by defective biogenesis of lysosome-related organelles, develop an accelerated form of progressive fibrotic lung disease. The etiology of pulmonary fibrosis associated with HPS-1 is unknown. To investigate the potential pathogenesis of pulmonary fibrosis in HPS-1, lung cells and proteins from individuals with HPS-1 were studied. Forty-one subjects with HPS-1 with and without pulmonary fibrosis were evaluated with pulmonary function tests, high-resolution computed tomography scan, and bronchoscopy. Bronchoalveolar lavage cells and analytes were analyzed. Concentrations of total bronchoalveolar lavage cells and alveolar macrophages were significantly higher in epithelial lining fluid from subjects with HPS-1 with and without pulmonary fibrosis compared with healthy research volunteers. Concentrations of cytokines and chemokines (i.e., monocyte chemoattractant protein-1, macrophage inflammatory protein-1alpha, and granulocyte-macrophage colony-stimulating factor) in alveolar epithelial lining fluid were significantly higher in subjects with HPS-1 with and without pulmonary fibrosis compared with healthy research volunteers (P system in which to study the pathogenesis and treatment of HPS pulmonary fibrosis.

    2009-01-01

    Testosterone levels are reduced in obesity, the metabolic syndrome and type 2 diabetes. Low testosterone levels are now being recognised as an independent risk factors for these conditions. Findings from men undergoing androgen suppression as treatment for prostate cancer confirm that the hypogonadal state increases body fat mass and serum insulin and there is a high rate of developing new diabetes in this population. Clinical trial data are consistent in showing reductions in body fat mass during testosterone replacement therapy. There are also trials showing improvements in insulin resistance and glycaemic control with testosterone. Most of the trials in this area to date have been of small size and the promising results require confirmation in larger trials, which are underway. In the longer term, large trials should be conducted to assess the potentially beneficial effects of testosterone on cardiovascular risk in this and other patient groups. In the meantime physicians involved in the care of men with diabetes should remain vigilant for the symptoms and signs of hypogonadism. Testosterone replacement therapy should be considered for those men with subsequently confirmed hypogonadism.

    ABSTRACT Background: Autoimmune polyendocrine syndrome type-1 (APS-1) is a rare, childhood onset disease caused by mutations in the Autoimmune Regulator gene. The phenotypic expression is highly variable and includes disease manifestations in the oral cavity, including mucocutaneous candidiasis. Increasing evidence suggests a potential role of the skin, oral and gut microbiotas in the pathogenesis of autoimmunity. To date, no information exists regarding the oral microbiota in APS-1. Objective: To assess the bacterial microbiota of whole saliva in APS-1 patients by using high throughput sequencing. Design: Whole unstimulated saliva was collected from 10 APS-1 patients and 17 healthy controls and examined by high throughput sequencing of the hypervariable region V1-V2 of 16S rRNA using the 454 GS Junior system. Metastats (http://cbcb.umd.edu/software/metastats) was used to analyse the pyrosequencing reads. Results: A reduction in the total number of bacterial genera and species was detected in APS-1 compared to healthy controls. The proportion of the major phyla Firmicutes was higher (60% vs 41%, p = 0.002) and Bacteroidetes lower (15% vs 28%, p = 0.007) in APS-1 compared to healthy controls. On the genus level, Streptococcus and Gemella were prevalent in APS-1. Conclusion: Our findings indicate a significantly altered oral microbiota in APS-1. PMID:29503707

    Auto-immune polyendocrine syndrome type 1 (APS1) also called Auto-immune Polyendocrinopathy Candidiasis Ectodermal Dystrophy (APECED) is a rare monogenic childhood-onset auto-immune disease. This autosomal recessive disorder is caused by mutations in the auto-immune regulator (AIRE) gene, and leads to autoimmunity targeting peripheral tissues. There is a wide variability in clinical phenotypes in patients with APSI, with auto-immune endocrine and non-endocrine disorders, and chronic mucocutaneous candidiasis. These patients suffer from oral diseases such as dental enamel hypoplasia and candidiasis. Both are frequently described, and in recent series, enamel hypoplasia and candidiasis are even the most frequent components of APS1 together with hypoparathyroidism. Both often occur during childhood (before 5 years old for canrdidiasis, and before 15 years old for enamel hypoplasia). Oral candidiasis is recurrent all life long, could become resistant to azole antifungal after years of treatment, and be carcinogenic, leading to severe oral squamous cell carcinoma. Oral components of APS1 should be diagnosed and rigorously treated. Dental enamel hypoplasia and/or recurrent oral candidiasis in association with auto-immune diseases in a young child should prompt APS1 diagnosis. Copyright © 2017 Elsevier Masson SAS.

    Hepatorenal syndrome is a severe complication of cirrhosis. Treatment with terlipressin has currently the best efficacy pedigree, inducing hepatorenal syndrome reversal in a high proportion of patients. However, hepatorenal syndrome recurrence after terlipressin withdrawal is very common, especially in type 2 hepatorenal syndrome. Midodrine, an oral adrenergic vasoconstrictor, has been suggested to be an effective therapy in hepatorenal syndrome. To analyse the impact of treatment with midodrine after hepatorenal syndrome type 2 reversal induced by terlipressin on the prevention of hepatorenal syndrome recurrence. A case-control design was used. The outcome of 10 patients with hepatorenal syndrome type 2 treated successfully with terlipressin and then with midodrine (7.5-12.5mg/tid) was compared with that of an historical control group of hepatorenal syndrome type 2 patients responders to treatment with terlipressin. Patients and controls were matched by age, plasma renin activity (PRA) levels and severity of renal and liver failure. Cases and controls were similar with respect to pre-treatment with terlipressin. The hepatorenal syndrome recurrence probability was the same in the two groups (cases and control: 9/10, 90%, p=ns). No significant differences were found between cases and controls with respect to serum creatinine (1.9+/-0.1mg/dl vs. 2+/-0.2mg/dl), blood creatinine clearance (28+/-5ml/min vs. 24+/-5ml/min), urinary sodium excretion (12+/-6mequiv./d vs. 19+/-4mequiv./d) and PRA levels (17+/-3ng/ml/h) vs. 20+/-3ng/ml/h) after terlipressin withdrawal (p=ns). These results show that in patients responders to terlipressin hepatorenal syndrome recurrence is not different between patients treated with midodrine and subjects who did not receive vasoconstrictor treatment after terlipressin withdrawal. These data suggest that midodrine is not effective in preventing hepatorenal syndrome type 2 recurrence.

    Principal component analysis (PCA) is a popular data analysis method. One of the motivations for using PCA in practice is to reduce the dimension of the original data by projecting the raw data onto a few dominant eigenvectors with large variance (energy). Due to the ubiquity of 1/f α noise in science and engineering, in this Letter we study the prototypical stochastic model for 1/f α processes--the fractional Brownian motion (fBm) processes using PCA, and find that the eigenvalues from PCA of fBm processes follow a power-law, with the exponent being the key parameter defining the fBm processes. We also study random-walk-type processes constructed from DNA sequences, and find that the eigenvalue spectrum from PCA of those random-walk processes also follow power-law relations, with the exponent characterizing the correlation structures of the DNA sequence. In fact, it is observed that PCA can automatically remove linear trends induced by patchiness in the DNA sequence, hence, PCA has a similar capability to the detrended fluctuation analysis. Implications of the power-law distributed eigenvalue spectrum are discussed

    In the last decade, increasing attention has been devoted to the extra-articular and extra-cutaneous manifestations of joint hypermobility syndrome, also termed Ehlers-Danlos syndrome, hypermobility type (i.e., JHS/EDS-HT). Despite the fact that the current diagnostic criteria for both disorders remain focused on joint hypermobility, musculoskeletal pain and skin changes, medical practice and research have started investigating a wide spectrum of visceral, neurological and developmental complications, which represent major burdens for affected individuals. In particular, children with generalized joint hypermobility often present with various neurodevelopmental issues and can be referred for neurological consultation. It is common that investigations in these patients yield negative or inconsistent results, eventually leading to the exclusion of any structural neurological or muscle disorder. In the context of specialized clinics for connective tissue disorders, a clear relationship between generalized joint hypermobility and a characteristic neurodevelopmental profile affecting coordination is emerging. The clinical features of these patients tend to overlap with those of developmental coordination disorder and can be associated with learning and other disabilities. Physical and psychological consequences of these additional difficulties add to the chief manifestations of the pre-existing connective tissue disorder, affecting the well-being and development of children and their families. In this review, particular attention is devoted to the nature of the link between joint hypermobility, coordination difficulties and neurodevelopmental issues in children. Presumed pathogenesis and management issues are explored in order to attract more attention on this association and nurture future clinical research. © 2015 Wiley Periodicals, Inc.

    Full Text Available Griscelli syndrome type 2 is a rare autosomal recessive disease caused by mutations in the RAB27A gene. It is characterized by pigmentary dilution of the skin and hair causing silvery gray hair, hemophagocytic lymphohistiocytosis and characteristic light microscopy findings in scalp hair shaft seen as large irregular clumps of pigment as opposed to the evenly distributed pigment along the hair shaft without any clumps. We describe a boy with classic features of Griscelli syndrome type 2 from Pakistan in whom a homozygous mutation in the RAB27A gene was identified that showed a single base substitution (c.598C>T predicted to cause premature protein termination (p.Arg200∗. We also present a clinical approach to silver blonde hair differentiating between the Griscelli syndrome types 1, 2 and 3, Chediak Hegashi Syndrome and Elejalde Syndrome.

    Trichorhinophalangeal syndrome type II is a rare genetic disorder with the few published case reports mainly reporting the radiographic skeletal manifestations. There are no published imaging reports of long bone cysts involving multiple bones in this condition. We report a unique case of bone cysts involving multiple long bones detected with MRI in a patient with trichorhinophalangeal syndrome type II complicated by a subsequent pathological fracture. It is possible that the bone cysts are a previously undescribed feature of this syndrome; however, the evidence is insufficient to establish a definite association. Chromosomal abnormality identified in this patient is consistent with trichorhinophalangeal syndrome type II with no unusual features. Although the nature of these bone cysts is unclear, they are one of the causes of the known increased fracture risk observed in this syndrome. (orig.)

    1975-03-07

    In a 59-year-old man in complete health a pure motor polyneuropathic syndrome with quadruplegia, swallowing and respiratory paralysis developed over a few hours. A few days later he died with the clinical picture of septicaemia. In a 59-year-old woman who had been investigated and treated for a suspected carcinoma for several months a predominantly distal sensomotoric polyneuropathy syndrome developed. The further course of disease was completely misleading as regards the diagnosis due to an acutely occurring transection syndrome with flaccid paraplegia, loss of reflexes, and bladder and rectal paralysis. Due to the very unusual neurological symptoms panarteritis nodosa was only diagnosed at autopsy and by histology in both cases. Panarteritis nodosa must be considered as a differential diagnosis in Landry-type polyneuropathy as well as in an acute spinal transection syndrome. The first patient demonstrates toxic damages, the second vascular damages of the nervous system which in general determine the neurological symptomatology of this vascular disease.

    Objective: To assess the prevalence of the metabolic syndrome in subjects diagnosed with Type 2 diabetes in Gorgan, Iran. Methods: Data were collected from 200 subjects with Type 2 diabetes mellitus and they were categorized as with or without the metabolic syndrome. Metabolic syndrome was diagnosed using Adult Treatment Panel-III (ATP-III) guidelines. Results: The overall metabolic syndrome prevalence was 51.50%. The mean age of all the subjects was 53.65+-9.50 years. There were 122 females and 78 males of whom 65 females and 38 males had the metabolic syndrome. The mean duration of diabetes was 7.70+-1.29 years. Mean triglycerides were 185.15+-56.63 mg/dl, and fasting blood glucose 153 +-19.6 mg/dl. These levels were significantly higher in the subjects with type-2 diabetes with metabolic syndrome, but the mean HDL-cholesterol was 37.96+-5.09 mg/dl and this was lower (p< 0.001). Female and male subjects with metabolic syndrome had significantly longer (except HDL-cholesterol) duration of diabetes, higher Triglyceride, and fasting blood glucose levels (p < 0.001, p < 0.05). Conclusion: This study showed a high prevalence of the metabolic syndrome in subjects with type 2 diabetes. Females were more affected than males. (author)

  3. Influenza A virus protein PB1-F2 exacerbates IFN-beta expression of human respiratory epithelial cells.

    The PB1-F2 protein of the influenza A virus (IAV) contributes to viral pathogenesis by a mechanism that is not well understood. PB1-F2 was shown to modulate apoptosis and to be targeted by the CD8(+) T cell response. In this study, we examined the downstream effects of PB1-F2 protein during IAV infection by measuring expression of the cellular genes in response to infection with wild-type WSN/33 and PB1-F2 knockout viruses in human lung epithelial cells. Wild-type virus infection resulted in a significant induction of genes involved in innate immunity. Knocking out the PB1-F2 gene strongly decreased the magnitude of expression of cellular genes implicated in antiviral response and MHC class I Ag presentation, suggesting that PB1-F2 exacerbates innate immune response. Biological network analysis revealed the IFN pathway as a link between PB1-F2 and deregulated genes. Using quantitative RT-PCR and IFN-β gene reporter assay, we determined that PB1-F2 mediates an upregulation of IFN-β expression that is dependent on NF-κB but not on AP-1 and IFN regulatory factor-3 transcription factors. Recombinant viruses knocked out for the PB1-F2 and/or the nonstructural viral protein 1 (the viral antagonist of the IFN response) genes provide further evidence that PB1-F2 increases IFN-β expression and that nonstructural viral protein 1 strongly antagonizes the effect of PB1-F2 on the innate response. Finally, we compared the effect of PB1-F2 variants taken from several IAV strains on IFN-β expression and found that PB1-F2-mediated IFN-β induction is significantly influenced by its amino acid sequence, demonstrating its importance in the host cell response triggered by IAV infection.

  6. Novel and recurrent MYO7A mutations in Usher syndrome type 1 and type 2.

    Directory of Open Access Journals (Sweden)

    Weining Rong

    Full Text Available Usher syndrome (USH is a group of disorders manifested as retinitis pigmentosa and bilateral sensorineural hearing loss, with or without vestibular dysfunction. Here, we recruited three Chinese families affected with autosomal recessive USH for detailed clinical evaluations and for mutation screening in the genes associated with inherited retinal diseases. Using targeted next-generation sequencing (NGS approach, three new alleles and one known mutation in MYO7A gene were identified in the three families. In two families with USH type 1, novel homozygous frameshift variant p.Pro194Hisfs*13 and recurrent missense variant p.Thr165Met were demonstrated as the causative mutations respectively. Crystal structural analysis denoted that p.Thr165Met would very likely change the tertiary structure of the protein encoded by MYO7A. In another family affected with USH type 2, novel biallelic mutations in MYO7A, c.[1343+1G>A];[2837T>G] or p.[?];[Met946Arg], were identified with clinical significance. Because MYO7A, to our knowledge, has rarely been correlated with USH type 2, our findings therefore reveal distinguished clinical phenotypes associated with MYO7A. We also conclude that targeted NGS is an effective approach for genetic diagnosis for USH, which can further provide better understanding of genotype-phenotype relationship of the disease.

    2016-05-01

    Full Text Available The article presents the results of researches of peculiarities of burnout syndrome formation in healthcare workers with different types of work motivation. It is discovered that the syndrome is formed for each motivational type as mechanism of psychological protection against the action of certain stressful factors, namely: for instrumental type – an excessive concentration on obtaining material rewards; for professional type – an excessive control of emotions in substantial professional communications and high psycho-emotional overload; for patriotic type – high level of dependence on social approval, a high level of communicative activity, a high level of psycho-emotional overload, for economical type – distrust, for lumpenized – any labor. Prevention of burnout syndrome in healthcare workers has to be realized taking into account peculiarities of psycho-traumatic factors depending on the type of work motivation.

    In the general population, habitual coffee consumption is inversely associated with the metabolic syndrome, a syndrome that is rather common also in patients with type 1 diabetes. However, whether coffee intake is beneficially related to the metabolic syndrome also in type 1 diabetes, is not known. We, therefore, studied the potential association between coffee consumption and the metabolic syndrome in a large population of individuals with type 1 diabetes. Furthermore, we investigated whether coffee consumption is associated with insulin resistance (estimated glucose disposal rate, eGDR), kidney function (estimated glomerular filtration rate, eGFR), and low-grade chronic inflammation (high-sensitivity C-reactive protein, hsCRP). Data from 1040 participants in the Finnish Diabetic Nephropathy Study were included in these cross-sectional analyses. Metabolic syndrome was assumed if at least 3 of the following cardiovascular risk factors were present: central obesity, high blood pressure, low HDL-cholesterol concentration, high triglyceride concentration, and hyperglycaemia. Subjects were categorized based on self-reported daily coffee intake: non-consumers (metabolic syndrome. Moreover, any level of coffee consumption was associated with increased risk of the blood pressure-component. An increasing trend was observed in the eGFR with increasing coffee consumption. In type 1 diabetes, high coffee intake is associated with the metabolic syndrome, and especially its blood pressure-component. Copyright © 2018. Published by Elsevier B.V.

  11. Type IV Ehlers-Danlos Syndrome: A Surgical Emergency? A Case of Massive Retroperitoneal Hemorrhage

    Chun, Stephen G; Pedro, Patrick; Yu, Mihae; Takanishi, Danny M

    2011-01-01

    Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

    Full Text Available Abstract Background Polymorphisms within the insulin gene can influence insulin expression in the pancreas and especially in the thymus, where self-antigens are processed, shaping the T cell repertoire into selftolerance, a process that protects from β-cell autoimmunity. Methods We investigated the role of the -2221Msp(C/T and -23HphI(A/T polymorphisms within the insulin gene in patients with a monoglandular autoimmune endocrine disease [patients with isolated type 1 diabetes (T1D, n = 317, Addison's disease (AD, n = 107 or Hashimoto's thyroiditis (HT, n = 61], those with a polyglandular autoimmune syndrome type II (combination of T1D and/or AD with HT or GD, n = 62 as well as in healthy controls (HC, n = 275. Results T1D patients carried significantly more often the homozygous genotype "CC" -2221Msp(C/T and "AA" -23HphI(A/T polymorphisms than the HC (78.5% vs. 66.2%, p = 0.0027 and 75.4% vs. 52.4%, p = 3.7 × 10-8, respectively. The distribution of insulin gene polymorphisms did not show significant differences between patients with AD, HT, or APS-II and HC. Conclusion We demonstrate that the allele "C" of the -2221Msp(C/T and "A" -23HphI(A/T insulin gene polymorphisms confer susceptibility to T1D but not to isolated AD, HT or as a part of the APS-II.

    Interstitial cystitis is regarded as a heterogenous syndrome with two distinguishable forms: the non-ulcer and the classic form of interstitial cystitis, the latter with Hunner's lesions; or bladder pain syndrome type 3C and non-Hunner bladder pain syndrome, respectively. A cohort of 379 patients diagnosed with interstitial cystitis was studied. Nitric oxide release from the bladder was measured using a chemiluminescence nitric oxide analyzer. Bladder biopsies from the patients and healthy controls were analyzed by routine histopathological examination. Biopsies from a subset of patients and controls were also analyzed by immunohistochemistry and cytokine gene expression by real-time polymerase chain reaction. Patients with bladder pain syndrome type 3C/classic interstitial cystitis had considerably higher levels of nitric oxide as compared with non-Hunner bladder pain syndrome/non-ulcer interstitial cystitis patients and healthy individuals, and showed histologically a chronic inflammation in the bladder mucosa, with abundant mast cell infiltration in all layers of the bladder wall. No inflammation was noted in non-Hunner bladder pain syndrome/non-ulcer interstitial cystitis patients. The isoenzymes inducible nitric oxide synthase, the catalyst in the nitric oxide production, was strongly expressed in the inflammatory cells in the bladder mucosa of bladder pain syndrome type 3C/classic interstitial cystitis patients. In addition, the expression of the pro-inflammatory cytokines interleukin-6 and interleukin-17A messenger ribonucleic acid, and of anti-inflammatory interleukin-10 messenger ribonucleic acid showed significantly increased levels in bladder pain syndrome type 3C/classic interstitial cystitis compared with healthy controls. Bladder pain syndrome type 3C/classic interstitial cystitis is a distinct inflammatory disease and in many aspects shares features of inflammatory autoimmune diseases. These findings could open up novel research avenues with

    Full Text Available Klinefelter's syndrome is rarely associated with hypocalcemia, especially pseudohypoparathyroidism (PHP type Ib. We describe a case of Klinefelter's syndrome associated with seizure, PHP type Ib and multiple endocrine dysfunctions. A 19-year-old Taiwanese male was admitted due to seizures with loss of consciousness. He had been diagnosed with Klinefelter's syndrome with seizure disorder and hypocalcemia 3 months previously. Physical examination revealed eunuchoidism but no osteodystrophy, while laboratory data revealed severe hypocalcemia, hyperphosphatemia, and elevated parathyroid hormone. Chromosomal study showed 47, XXY. Osteoporosis was found on chest and abdominal radiography. Dense calcification in the cerebrum and cerebellum was shown on brain computed tomography and magnetic resonance imaging. Elevation of the patient's serum calcium level was noted after vitamin D and calcium carbonate supplements were given. Klinefelter's syndrome is rarely associated with PHP type Ib; our patient's hypocalcemia improved after long-term aggressive treatment.

    Waardenburg syndrome mutations are most often recurrent or de novo. The rate of familial recurrence is low and families with several affected children are extremely rare. In this study, we aimed to clarify the underlying hereditary cause of Waardenburg syndrome type I in two siblings in a Chinese family, with a mother affected by prelingual mild hearing loss and a father who was negative for clinical symptoms of Waardenburg syndrome and had a normal hearing threshold. Complete characteristic features of the family members were recorded and genetic sequencing and parent-child relationship analyses were performed. The two probands were found to share double mutations in the PAX3/GJB2 genes that caused concurrent hearing loss in Waardenburg syndrome type I. Their mother carried the GJB2 c.109G > A homozygous mutation; however, neither the novel PAX3 c.592delG mutation, nor the Waardenburg syndrome phenotype, was observed in either parent. These previously unreported digenic mutations in PAX3/GJB2 resulted in deafness associated with Waardenburg syndrome type I in this family. To our knowledge, this is the first report describing germinal mosaicism in Waardenburg syndrome. This concept is important because it complicates genetic counseling of this family regarding the risk of recurrence of the mutations in subsequent pregnancies. Copyright © 2017 Elsevier B.V.

    According to the recent definition proposed by the Consensus conference on Acute Dialysis Quality Initiative Group, the term cardio-renal syndrome (CRS) has been used to define different clinical conditions in which heart and kidney dysfunction overlap. Type 1 CRS (acute cardio- renal syndrome) is characterized by acute worsening of cardiac function leading to AKI (5, 6) in the setting of active cardiac disease such as ADHF, while type - 2 CRS occurs in a setting of chronic heart disease. Type 3 CRS is closely link to acute kidney injury (AKI), while type 4 represent cardiovascular involvement in chronic kidney disese (CKD) patients. Type 5 CRS represent cardiac and renal involvement in several diseases such as sepsis, hepato - renal syndrome and immune - mediated diseases. Copyright © 2017 Cardiological Society of India.

    Full Text Available Wolfram syndrome is a rare autosomal recessive disorder characterized by a constellation of disorders also known as diabetes insipidus, diabetes mellitus (DM, optic atrophy, and deafness. Patients present with DM and optic atrophy in the first decade, diabetes insipidus and sensorineural deafness in the second decade, and renal outflow tract anomalies and other neurological manifestations later in life. We report a case of a 14-year-old boy who was diagnosed with insulin-dependent DM and subsequently discovered to have optic atrophy, sensorineural hearing loss, and cardiovascular defect with a positive family history. Such cases need to be evaluated thoroughly with respect to Wolfram syndrome and its associated anomalies.

    Full Text Available Pfeiffer syndrome is a rare autosomal dominant disease that affects almost 1 out of every 100,000 live newborns, and it is associated with craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly in hands and feet. Three types of this syndrome have been described based on the presence of other abnormalities and the severity of the condition. “Classic” type 1 consists of mild severity with normal to near-normal intelligence and generally a good prognosis. Type 2 is characterized by a cloverleaf skull, severe proptosis, elbow ankylosis or synostosis, growth retardation and life-threatening neurological and respiratory complications. Type 3 is similar to type 2 but without the cloverleaf cranium. This syndrome is genetically heterogeneous, it is caused by mutations in the fibroblast growth factor receptor genes FGFR- 1 or FGFR-2. Occasionally Pfeiffer syndrome can be diagnosed prenatally by sonography or molecularly if the causative mutation is known. Management must be multidisciplinary and it includes multiple-staged surgery. In this report we present the clinical and radiographic findings in female newborn, whose clinical features were consistent with Pfeiffer syndrome type 2. A brief updated review of the literature is included.

    Full Text Available Diabetes mellitus type 2 and metabolic syndrome are conditions associated with insulin resistance and hyperglycemia. Metabolic syndrome is a risk factor for diabetes mellitus type 2. Plasma glucose (fasting/postprandial and serum ceruloplasmin levels and their relationship were studied. Study population consisted of 150 individuals—50 individuals with diabetes mellitus type 2, 50 individuals with metabolic syndrome, and 50 age- and sex-matched healthy controls. Plasma levels of fasting and postprandial glucose were measured along with serum ceruloplasmin. Data was analyzed by ANOVA and Pearson correlation. The fasting and postprandial plasma glucose levels in metabolic syndrome and diabetes mellitus type 2 were increased when compared to control. Serum ceruloplasmin level was 327.8 ± 68.9 in control, 227.3 ± 46.8 in metabolic syndrome, and 194.0 ± 49.6 in diabetes mellitus type 2 individuals. There was a statistically significant negative correlation between the fasting, postprandial plasma glucose, and serum ceruloplasmin in type 2 diabetes mellitus.

    This study aimed to evaluate the effect of coffee drinking on clinical markers of diabetes and metabolic syndrome in Zucker rats. Diabetic Zucker rats with metabolic syndrome and control Zucker rats were used for in vivo tests. The animals received daily doses of coffee drink by gavage for 30 days. After the treatment, the levels of glucose, triglycerides, total cholesterol and fractions, creatinine, uric acid, activity of aspartate aminotransferase and alanine aminotransferase were evaluated. Urea and creatinine levels were also analyzed in urine. By collaborating in the modulation of the metabolic syndrome and diabetes mellitus type 2, coffee drink helped in reducing serum glucose, total cholesterol and triglycerides. The results demonstrate that treatment with roasted coffee drink, because of its hypoglycemic and hypolipidemic effect, is efficient in the protection of animals with metabolic syndrome and diabetes mellitus type 2.

    BACKGROUND: Coffee is one of the most widely consumed beverages. We tested the hypothesis that genetically high coffee intake is associated with low risk of obesity, metabolic syndrome and type 2 diabetes, and with related components thereof. METHODS: We included 93,179 individuals from two large...... general population cohorts in a Mendelian randomization study. We tested first whether high coffee intake is associated with low risk of obesity, metabolic syndrome and type 2 diabetes, and with related components thereof, in observational analyses; second, whether five genetic variants near the CYP1A1......, CYP1A2 and AHR genes are associated with coffee intake; and third, whether the genetic variants are associated with obesity, metabolic syndrome and type 2 diabetes, and with related components thereof. Finally, we tested the genetic association with type 2 diabetes in a meta-analysis including up...

    Margolis reported on a large pedigree with a {open_quotes}new{close_quotes} X-linked syndrome of profound deafness and albinism (MIM 300700, albinism-deafness syndrome). The affected males presented with profound deafness and severe pigmentary abnormalities of the skin. At birth the skin appeared as almost albinotic except for areas of light pigmentation over the gluteal and scrotal areas, and thereafter pigmentation gradually increased over the body. Skin changes ultimately included areas of hypopigmentation and spots of hyperpigmentation. Some of the affected males also had blue irides, heterochromia, or segmental color iris changes. In carrier females, variable hearing impairment was documented without any pigmentary changes. 9 refs., 1 fig.

    Complex regional pain syndrome type 1 is a disabling pain disorder with unclear etiology. It is usually triggered by an injury to a limb with or without specific nerve injury. The objective of this study is to explore the risk factors and predictors for this disease utilizing a large national database. Retrospective analysis of the Nationwide Inpatient Sample database from 2007 to 2011 in the United States. Adult inpatients diagnosed with complex regional pain syndrome type 1. Chi-square, simple and multivariate logistic regression analyses were conducted. The regression model was adjusted to the patient's demographics and comorbidities. There were 22,533 patients with the discharge diagnosis of complex regional pain syndrome type 1 of an inpatient sample of 33,406,123. It peaks between age 45 and 55. Female gender, Caucasian race, higher median household income, headache, depression, drug abuse and private insurance patients (vs Medicaid patients) were associated with higher rate of complex regional pain syndrome type 1. On the other hand, diabetes, obesity, hypothyroidism, and anemia were associated with a lower rate. Utilizing a large database, our study added more information to the risk profile of the complex regional pain syndrome type 1 in an inpatient population. Such information should be useful for physician for early recognition, diagnosis of patients at risk. Copyright © 2017 Elsevier Inc. All rights reserved.

    To measure the relation of creatinine clearance in type-2 diabetic patients with different components of metabolic syndrome and to quantify the relationship of frequency of incident CKD with increasing number of metabolic syndrome components while controlling for age, gender and duration of diabetes. Cross-sectional descriptive study. Diabetes Clinic, Fauji Foundation Hospital, Rawalpindi, from January to August 2006. Patients having type-2 Diabetes for more than 5 years were enrolled. Information regarding age, gender, duration of diabetes , type of diabetes, treatment taking, complete fasting lipid profile, fasting blood glucose, Body Mass Index (BMI), 24 hours urinary proteins and creatinine clearance, co-existent risk factors like hypertension and ischemic heart disease was taken. Patients were divided into groups having one to all five metabolic syndrome traits. Progressive increase in the metabolic syndrome traits was compared with decline in creatinine clearance. Pearson correlation test and multiple logistic regression were applied to determine correlation with significance at 'r' and 'p' creatinine clearance, 37% had a creatinine clearance between 60-90 ml/min, 19% had a creatinine clearance of 30-59 ml/min, 18% had a creatinine clearance of less than 30 ml/min and 10% were already in stage 5 CKD. The decline in renal function was more severe in subjects evaluated who had a higher number of features of the metabolic syndrome. Age was the only significant determinant of development of CKD (p=0.05). The renal function progressively declined with 3 or more features of the metabolic syndrome.

    The F1F0 complex of Paracoccus denitrificans (PdF1F0) is the fastest ATP synthase but the slowest ATPase. Sulfite exerts maximal activation of the PdF1F0-ATPase (Pacheco-Moisés, F., García, J. J., Rodríguez-Zavala, J. S., and Moreno-Sánchez, R. (2000). Eur J. Biochem. 267, 993-1000) but its effect on the PdF1F0-ATP synthase activity remains unknown. Therefore, we studied the effect of sulfite on ATP synthesis and 32Pi ATP exchange reactions of inside-out membrane vesicles of P. denitrificans. Sulfite inhibited both reactions under conditions of maximal delta pH and normal sensitivity to dicyclohexylcarbodiimide. Sulfite increased by 10- and 5-fold the K0.5 for Mg2+-ADP and Pi during ATP synthesis, respectively, and by 4-fold the IC50 of Mg2+-ADP for inhibition of the PdF1F0-ATPase activity. Thus, sulfite exerts opposite effects on the forward and reverse functioning of the PdF1F0 complex. These effects are not due to membrane or PdF1F0 uncoupling. Kinetic and structural modifications that could account for these results are discussed.

    Chronic fatigue is an important contributor to impaired health-related quality of life in Ehlers-Danlos syndrome. There is overlap in the symptoms and findings of EDS and chronic fatigue syndrome. A proportion of those with CFS likely have EDS that has not been identified. The evaluation of chronic fatigue in EDS needs to include a careful clinical examination and laboratory testing to exclude common causes of fatigue including anemia, hypothyroidisim, and chronic infection, as well as dysfunction of major physiological or organ systems. Other problems that commonly contribute to fatigue in EDS include sleep disorders, chronic pain, deconditioning, cardiovascular autonomic dysfunction, bowel and bladder dysfunction, psychological issues, and nutritional deficiencies. While there is no specific pharmacological treatment for fatigue, many medications are effective for specific symptoms (such as headache, menstrual dysfunction, or myalgia) and for co-morbid conditions that result in fatigue, including orthostatic intolerance and insomnia. Comprehensive treatment of fatigue needs to also evaluate for biomechanical problems that are common in EDS, and usually involves skilled physical therapy and attention to methods to prevent deconditioning. In addition to managing specific symptoms, treatment of fatigue in EDS also needs to focus on maintaining function and providing social, physical, and nutritional support, as well as providing on-going medical evaluation of new problems and review of new evidence about proposed treatments. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    The prevalence of metabolic syndrome is raising worldwide; however, the role of diet in the origin of metabolic syndrome is not understood well. This study identifies major dietary patterns among type 2 diabetes mellitus patients with and without metabolic syndrome; and its association with metabolic syndrome components in Gaza Strip, Palestine. This cross sectional study was conducted among 1200 previously diagnosed type 2 diabetes mellitus (both genders, aged 20 - 64 years) patients receiving care in primary healthcare centers in Gaza Strip, Palestine. Metabolic syndrome was defined based on the International Diabetes Federation criteria; dietary patterns were evaluated using a validated semi-quantitative food frequency questionnaire. Statistical analysis was performed using SPSS version 20. Two major dietary patterns were identified by factor analysis: Asian-like pattern and sweet-soft drinks-snacks pattern. After adjustment for confounding variables, patients in the highest tertile of the Asian-like pattern characterized by a high intake of whole grains, potatoes, beans, legumes, vegetables, tomatoes and fruithad a lower odds for (Metabolic syndrome, central obesity, high triglycerides, low HDL cholesterol and high blood pressure), (OR 0.766 CI 95% (.642-.914)), (OR 0.797 CI 95% (.652-.974)), (OR 0.791 CI 95% (.687-.911)), (OR 0.853 CI 95% (.743-.978)) and (OR 0.815 CI 95% (.682-.973)) respectively, (P value metabolic syndrome and its components.

    To assess associations of metabolic syndrome, and its individual components, with extent of severe periodontitis among patients with type 2 diabetes mellitus (T2DM). We performed a secondary data analysis (N = 283) using a cross-sectional study population of Gullah African Americans with T2DM. Extent of severe periodontitis was assessed as total diseased tooth-sites/person [evaluated as separate outcomes: 6+mm clinical attachment level (CAL), 5+mm periodontal probing depth (PPD)] using negative binomial regression techniques. Primary independent variables assessed in separate models included metabolic syndrome (yes/no), each metabolic syndrome component (low HDL, hypertension, high triglycerides, large waist circumference) and glycemic control (poor/good). Multivariable CAL-model results showed a significant association for metabolic syndrome status with extent of severe periodontitis (RR = 2.77, p = 0.03). The separate multivariable CAL-model including each metabolic syndrome component showed marginally increased rates among those with large waist circumference (RR = 2.33, p = 0.09) and those with HbA1c ≥ 7% (RR = 1.73, p = 0.06). Multivariable PPD-models showed marginally increased rates among those with metabolic syndrome (RR = 2.18, p = 0.06). Metabolic syndrome is associated with the extent of severe periodontitis in this Gullah population with T2DM. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Turcot syndrome is an autosomal recessive disorder clinically characterized by the occurrence of primary tumors of the central nervous system and adenomatous colonic polyps during the first or second decades of life, with a spectrum of clinical features such as “café-au-lait” spots, axillary freckling, and hyperpigmented spots. Currently its prevalence globally and in Colombia remains unknown. We present the case of a 20-year-old male with a clinical presentation of both glioblastoma multiforme and multiple adenomatous colonic polyps. The molecular genetics study revealed a mutation in KrasAsp12 gene and altered expression of HMSH2 and HMSH6 proteins encoded by the DNA mismatch repair genes in two of the colonic polyps. Even though this clinical presentation may suggest a shorter survival rate, this patient is still alive after seven months of treatment. A literature review complements this report.

    Full Text Available The diagnosis of child maltreatment leading to head injury is challenging. Here, we present the case of a 3-month-old female infant who presented with focal seizures that lasted for several minutes. After admission, she began to show intermittent clusters of head nods, irritable crying, arching, writhing, stiffening, and jerking of both arms. These results and electroencephalography findings were attributed as the diagnosis of infantile spasms (IS. Brain computed tomography and magnetic resonance imaging (MRI revealed the presence of chronic subdural hematoma mixed with acute ischemic injuries. Examination of the eye fundus confirmed the presence of retinal hemorrhage. Therefore, all evidence pointed to a diagnosis of shaken baby syndrome (SBS. Based on this case, we suggest that physicians should consider a diagnosis of SBS for children with new-onset IS and that should be evaluated, diagnosed, and treated as promptly as possible.

    Full Text Available Objectives The aim of this study was to investigate the prevalence of metabolic syndrome, in children with type one diabetes mellitus (T1DM for the first time in a population in the Middle East, and assess the influence of type of insulin therapy, daily dosage of insulin, family history of type 2 diabetes, gender and level of HbA1c on the prevalence of metabolic syndrome. Methods This cross-sectional study was conducted on children with T1DM aged 2 years during years 2013 to 2014. Waist circumference, blood pressure, height and weight of children with diabetes, for calculation of body mass index (BMI, were measured by one physician. Fasting blood glucose and lipids were also measured. According to the age-modified standards of the ATPIII, metabolic syndrome was defined. All data were analyzed using the SPSS 18 software. Results In this study, 87 children with diabetes (48 females and 39 males aged 12.38 ± 4.2 were enrolled. Overall, 40.9% of our patients had hypertension, 55.2% had hypertriglyceridemia, 36.8% had low high-density lipoprotein (HDL and 6.9% of patients had abdominal obesity. Furthermore, 29.9% of these children had metabolic syndrome, which did not have a significant association with the type of insulin regimen (P = 0.97, nor the daily dosage of insulin (P = 0.234, however the serum concentration of HbA1c had a significant correlation with metabolic syndrome (P = 0.027. Conclusions This study provides evidence indicating high prevalence of metabolic syndrome in children with T1DM in southern Iran. Preventive programs aimed towards decreasing the risk factors of metabolic syndrome and interpretation of a healthier diet and physical activity for children with T1DM should be considered in our country.

    The kyphoscoliotic type of the Ehlers-Danlos syndrome is an autosomal recessive connective tissue disorder characterized by soft extensible skin, laxity of joints, severe muscle hypotonia at birth, and kyphoscoliosis. We describe a 3-year-old girl with the kyphoscoliotic type of the Ehlers-Danlos syndrome whose parents were cousins. She was born with breech presentation by vaginal delivery at term after a normal pregnancy. At birth she manifested hypotonia and congenital kyphosis. On the second postnatal day, subdural and intraparenchymal hemorrhages were detected by magnetic resonance imaging. During follow-up at 18 months of age, strabismus, umbilical hernia, kyphoscoliosis, joint laxity, bilateral hip dislocation, muscular hypotonia, and motor developmental delay. The cranial magnetic resonance imaging revealed periventricular leukomalacia and abnormal signal related to previous hemorrhage. Metabolic investigations and neuromuscular evaluation were normal, excluding other possible explanations of hypotonia. An analysis of urinary cross-links demonstrated an increase in the lysyl-pyridinoline to hydroxylysyl-pyridinoline ratio, suggesting the diagnosis of kyphoscoliotic type of the Ehlers-Danlos syndrome. Molecular analysis of the PLOD1 gene revealed that she had a novel homozygous p.Pro622Argfs*3 (c. 1863_1864dupCG) mutation in exon 17 that is expected to cause complete loss of the enzyme lysyl hydroxylase 1 and to cause kyphoscoliotic type of the Ehlers-Danlos syndrome. We describe a child with the kyphoscoliotic type of the Ehlers-Danlos syndrome with a novel mutation of the PLOD1 gene. Our observations suggest that vascular lesions in the neonatal period may be a rare additional clinical feature of kyphoscoliotic type of the Ehlers-Danlos syndrome. Copyright © 2014 Elsevier Inc.

    Epidemiological studies report a high prevalence of type 2 diabetes and metabolic syndrome in the island nation of Mauritius. The Mauritius Family Study was initiated to examine heritable factors that contribute to these high rates of prevalence and consists of 400 individuals in 24 large extended multigenerational pedigrees. Anthropometric and biochemical measurements relating to the metabolic syndrome were undertaken in addition to family and lifestyle based information for each individual. Variance components methods were used to determine the heritability of the type 2 diabetes and metabolic syndrome related quantitative traits. The cohort was made up of 218 females (55%) and 182 males with 22% diagnosed with type 2 diabetes and a further 30% having impaired glucose tolerance or impaired fasting glucose. Notably BMI was not significantly increased in those with type 2 diabetes (P= .12), however a significant increase in waist circumference was observed in these groups (P= .02). The heritable proportion of trait variance was substantial and greater than values previously published for hip circumference, LDL and total cholesterol, diastolic and systolic blood pressure and serum creatinine. Height, weight and BMI heritabilities were all in the upper range of those previously reported. The phenotypic characteristics of the Mauritius family cohort are similar to those previously reported in the Mauritian population with a high observed prevalence rate of type 2 diabetes. A high heritability for key type 2 diabetes and metabolic syndrome related phenotypes (range 0.23 to 0.68), suggest the cohort will have utility in identifying genes that influence these quantitative traits.

  9. Massively parallel DNA sequencing facilitates diagnosis of patients with Usher syndrome type 1.

    Full Text Available Usher syndrome is an autosomal recessive disorder manifesting hearing loss, retinitis pigmentosa and vestibular dysfunction, and having three clinical subtypes. Usher syndrome type 1 is the most severe subtype due to its profound hearing loss, lack of vestibular responses, and retinitis pigmentosa that appears in prepuberty. Six of the corresponding genes have been identified, making early diagnosis through DNA testing possible, with many immediate and several long-term advantages for patients and their families. However, the conventional genetic techniques, such as direct sequence analysis, are both time-consuming and expensive. Targeted exon sequencing of selected genes using the massively parallel DNA sequencing technology will potentially enable us to systematically tackle previously intractable monogenic disorders and improve molecular diagnosis. Using this technique combined with direct sequence analysis, we screened 17 unrelated Usher syndrome type 1 patients and detected probable pathogenic variants in the 16 of them (94.1% who carried at least one mutation. Seven patients had the MYO7A mutation (41.2%, which is the most common type in Japanese. Most of the mutations were detected by only the massively parallel DNA sequencing. We report here four patients, who had probable pathogenic mutations in two different Usher syndrome type 1 genes, and one case of MYO7A/PCDH15 digenic inheritance. This is the first report of Usher syndrome mutation analysis using massively parallel DNA sequencing and the frequency of Usher syndrome type 1 genes in Japanese. Mutation screening using this technique has the power to quickly identify mutations of many causative genes while maintaining cost-benefit performance. In addition, the simultaneous mutation analysis of large numbers of genes is useful for detecting mutations in different genes that are possibly disease modifiers or of digenic inheritance.

  10. The impaired proprioception in Ehlers-Danlos Syndrome-Hypermobility Type/Joint hypermobility Syndrome: the rehabilitation role

    Full Text Available Ehlers-Danlos Syndrome Hypermobility Type/Joint Hypermobility Syndrome (JHS/EDS-HT is an hereditary disorder of the connective tissue mainly manifesting with generalized joint hypermobility and skin hyperextensibility with an involvement of the connective tissue matrix proteins. Collagen alterations may influence the quality of movement in these patients but also movement has a role for the collagen quality: motion has a prevention role in the formation of contractures and adhesions. A poor sense of proprioception correlated with the collagenous connective tissues alterations could explain why people with JHS/EDS-HT become injured, having a lack of sensation of the joint at the end of the range. Rehabilitation approach may consider all these aspects.

    2010-01-01

    BACKGROUND Polycystic ovary syndrome (PCOS) is a common condition in reproductive-aged women associated with impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and the metabolic syndrome. METHODS A literature search was conducted (MEDLINE, CINAHL, EMBASE, clinical trial registries and hand-searching) identifying studies reporting prevalence or incidence of IGT, DM2 or metabolic syndrome in women with and without PCOS. Data were presented as odds ratio (OR) [95% confidence interval (CI)] with fixed- and random-effects meta-analysis by Mantel-Haenszel methods. Quality testing was based on Newcastle-Ottawa Scaling and The Cochrane Collaboration's risk of bias assessment tool. Literature searching, data abstraction and quality appraisal were performed by two investigators. RESULTS A total of 2192 studies were reviewed and 35 were selected for final analysis. Women with PCOS had increased prevalence of IGT (OR 2.48, 95% CI 1.63, 3.77; BMI-matched studies OR 2.54, 95% CI 1.44, 4.47), DM2 (OR 4.43, 95% CI 4.06, 4.82; BMI-matched studies OR 4.00, 95% CI 1.97, 8.10) and metabolic syndrome (OR 2.88, 95% CI 2.40, 3.45; BMI-matched studies OR 2.20, 95% CI 1.36, 3.56). One study assessed IGT/DM2 incidence and reported no significant differences in DM2 incidence (OR 2.07, 95% CI 0.68, 6.30). One study assessed conversion from normal glucose tolerance to IGT/DM2 (OR 2.4, 95% CI 0.7, 8.0). No studies reported metabolic syndrome incidence. CONCLUSIONS Women with PCOS had an elevated prevalence of IGT, DM2 and metabolic syndrome in both BMI and non-BMI-matched studies. Few studies have determined IGT/DM2 or metabolic syndrome incidence in women with and without PCOS and further research is required.

    Osteogenesis imperfecta (OI) and Ehlers-Danlos syndrome (EDS) are rare genetic disorders that are typically inherited in an autosomal dominant manner. Few cases of OI/EDS overlap syndrome have been documented. Described here is a 30-year-old Chinese male with OI type III and EDS. Sequencing of genomic DNA revealed a heterozygous COL1A1 mutation (c.671G>A, p.Gly224Asp) that affected the N-anchor domain of the alpha 1 chain of collagen type I. Ultrastructural analysis of a skin biopsy specimen revealed thin collagen fibers with irregular alignment of collagen fibers. These findings have expanded the genotypic spectrum of the OI/EDS overlap syndrome.

    1986-01-01

    The clinical, radiological and biochemical findings in a black girl with a rare, inherited mucopolysaccharide storage disease, Sanfilippo's syndrome (mucopoly-saccharidosis (MPS) III) type C, are described. Practical points concerning the biochemical diagnosis of this condition, arising from unusual characteristics of the deficient enzyme acetyl CoA: α-glucosaminide N-acetyltransherase, are discussed. Some information also occurs about the abnormal uptake of radiolabelled sulphur ( 35 SO 4 ). Because phenotypic manifestations of mucopolysaccharidosis are mild in all four types of Sanfilippo's syndrome and screening tests for mucopolysacchariduria in these patients may be negative, many cases may be passed unrecognized or simply labelled as cases of nonspecific mental retardation. It is suggested that Sanfilippo's syndrome is grossly underdiagnosed in the RSA and clinicians are urged to develop a greater awareness of the existence, and often subtle presentation, of the condition

    2017-04-01

    We report on a 58-year old woman with microcephaly, mild dysmorphic features, bilateral keratoconus, digital abnormalities, short stature and mild cognitive delay. Except for keratoconus, the phenotype was suggestive for Feingold syndrome type 2 (FGLDS2, MIM 614326), a rare autosomal dominant disorder described in six patients worldwide, due to the haploinsufficiency of MIR17HG, a micro RNA encoding gene. Karyotype showed a de novo deletion on chromosome 13q, further defined by array-Comparative Genomic Hybridization (a-CGH) to a 17.2-Mb region. The deletion included MIR17HG, as expected by the FGLDS2 phenotype, and twelve genes from the keratoconus type 7 locus. Because our patient presented with keratoconus, we propose she further refines disease genes at this locus. Among previously suggested candidates, we exclude DOCK9 and STK24, and propose as best candidates IPO5, DNAJC3, MBNL2 and RAP2A. In conclusion, we report a novel phenotypic association of Feingold syndrome type 2 and keratoconus, a likely contiguous gene syndrome due to a large genomic deletion on 13q spanning MIR17HG and a still to be identified gene for keratoconus.

    2015-01-01

    The Fast Beam Condition Monitor BCM1F consists of 24 single-crystal CVD 5 mm x 5 mm diamonds positioned 1.8 m on either side of the interaction point at a radius of 6.5 cm from the beam pipe. The signal is read out, shaped by a frontend ASIC, and converted to an optical signal which is then transmitted to the backend electronics in USC55. The data travels parallel paths: a discriminator path registers the time of signal pulses and transfers this information to dedicated fast readout electronics, while an ADC system captures full orbits for monitoring studies but is prevented from acting as data readout by a high deadtime. BCM1F provides information on the condition of the beam and ensures that the inner detector occupancy is sufficiently low for data-taking. In addition to providing beam information, BCM1F also detects collisions and as such can be used as a luminometer.

    Full Text Available BACKGROUND Hepatorenal syndrome is a pre-renal like dysfunction that generally onsets in cirrhotic patients presenting ascites. MATERIALS AND METHODS We investigated the improvement of renal function in subjects with hepatorenal syndrome after terlipressin administration and the survival times after this treatment. 30 patients affected by cirrhosis, with diagnosis of type I hepatorenal syndrome were treated with intravenous terlipressin plus albumin (group A or with albumin alone (group B. Liver function, renal function, sodium plasma level and plasma renin activity were monitored. RESULTS Patients of group A showed a significant improvement (p < 0.001 of renal function valued by creatinine rate compared with the results obtained in group B. The probability of survival was higher in the group A (p < 0.0001. CONCLUSIONS Our results seem to confirm that the administration of terlipressin plus albumin improves renal function in patients with cirrhosis and type I hepatorenal syndrome and that a reversal of hepatorenal syndrome is strongly associated with an improved survival.

    We describe the case of a boy with steroid-sensitive nephrotic syndrome coexisting with type-1 diabetes mellitus. Nephrotic syndrome was diagnosed in a boy (age 3 years and 11 months) with generalized edema. Marked weight loss (23 to 16 kg), polyuria, polydipsia and weakness were observed after three weeks of treatment with prednisone 2 mg/kg/day. Diabetic ketoacidosis was confirmed by laboratory tests: hyperglycemia (glucose 657 mg/dl), glycosuria without proteinuria, acidosis and ketonuria. Therapy with insulin and prednisone was started. He was then maintained on a daily dose of NPH insulin. At age 4 years and 1 month a new episode of ketoacidosis without proteinuria occurred in association with a viral infection of the upper airways. At age 4 years and 4 months nephrotic syndrome relapsed, but the child responded well to steroid therapy. There was another relapse three months later, when prednisone treatment was interrupted. This led to the introduction of cyclophosphamide, with good results. Since then, the patient (now 5 years and 6 months old) has been taking insulin daily and nephrotic syndrome has not relapsed. Plasma levels of C3 and C4 and renal function are normal. Hematuria is occasionally present. Anti-GAD antibodies (glutamic decarboxilase) are normal and anti-islet cell antibodies are positive. HLA antigens: A2; B44; B52; DR4; DR8; DR53. The simultaneous occurrence of steroid-sensitive nephrotic syndrome and type-1 diabetes mellitus is rare.

    2014-06-01

    Type 3 autoimmune polyendocrine syndrome (APS-3) is defined by the presence of an autoimmune thyroid disease and another autoimmune illness, excluding Addison's disease; this is a frequent combination. We report the case of a 55 years old female patient with APS-3, with seven clinical or latent autoimmune manifestations. At 49 years of age she was admitted at the General Hospital for leukopenia, weight loss, tremors, anxiety and diarrhea. The personal history revealed ulcerative colitis and, during the last year, episodes of fever with migrant arthralgia and cutaneous lesions. The patient was evaluated for thyroid function and imaging, mielobiopsy, glycaemic control, gastrointestinal and rheumatologic disorders with specific biochemical tests, imaging and endoscopic procedures. We concluded that the patient was affected by APS-3, characterized by the association of Graves' disease, autoimmune leukopenia, latent autoimmune diabetes of the adult (LADA), autoimmune gastritis, ulcerative colitis, Sjögren's and anti-phospholipid syndromes. The patient started low doses of corticosteroid drugs for leukopenia, underwent (131)I therapy for hyperthyroidism and later started substitutive thyroid therapy with l-thyroxine, insulin therapy for LADA, mesalazine for ulcerative colitis and artificial tears for Sjögren's syndrome. In this article we report a complex case of APS-3, characterized by the association of seven different autoimmune diseases, which required a complex therapeutic strategy.

    To measure the relation of creatinine clearance in type-2 diabetic patients with different components of metabolic syndrome and to quantify the relationship of frequency of incident CKD with increasing number of metabolic syndrome components while controlling for age, gender and duration of diabetes. Cross-sectional descriptive study. Patients having type-2 Diabetes for more than 5 years were enrolled. Information regarding age, gender, duration of diabetes, type of diabetes, treatment taking, complete fasting lipid profile, fasting blood glucose, Body Mass Index (BMI), 24 hours urinary proteins and creatinine clearance, co-existent risk factors like hypertension and ischemic heart disease was taken. Patients were divided into groups having one to all five metabolic syndrome traits. Progressive increase in the metabolic syndrome traits was compared with decline in creatinine clearance. Pearson correlation test and multiple logistic regression were applied to determine correlation with significance at r and p <0.05. Out of 104 evaluated female and male patients, 70% had hypertension, ischemic heart disease and a family history of diabetes. While 20% had normal creatinine clearance, 37% had a creatinine clearance between 60-90 ml/min, 19% had a creatinine clearance of 30-59 ml/min, 18% had a creatinine clearance of less than 30 ml/min and 10% were already in stage 5 CKD. The decline in renal function was more severe in subjects evaluated who had a higher number of features of the metabolic syndrome. Age was the only significant determinant of development of CKD (p=0.05). The renal function progressively declined with 3 or more features of the metabolic syndrome. (author)

    2006-10-01

    Although no major advances have occurred in the curative treatment of reflex sympathetic dystrophy syndrome (RSDS), new pathogenic insights may soon lead to innovative approaches, which may also prove effective in alleviating some forms of neuropathic pain. Preventing nerve compression and ischemia-reperfusion injury constitute valuable measures for preventing RSDS. Vitamin C administration can also prevent RSDS, together with clonidine in high-risk patients. Short-term glucocorticoid therapy has been found effective in preventing RSDS after stroke but has not been evaluated in other situations. Beneficial effects of bisphosphonates have been documented in several placebo-controlled trials. Placebo-controlled trials of ketamine and spinal cord stimulation are in order to confirm or refute the promising results obtained in open-label studies. Mirror visual feedback was introduced recently for the rehabilitation of patients with RSDS but needs to be evaluated in randomized controlled trials.

    To observe hemodynamic characteristics and the correlation with syndrome types of traditional Chinese medicine (TCM) in patients with septic shock, so as to direct the treatment based on syndrome differentiation. A prospective observation was conducted. Sixty-eight patients with septic shock admitted to the Department of Critical Care Medicine of Dade Road General Hospital of Guangdong Hospital of TCM from January 2013 to July 2015 were enrolled. Pulse indicating continuous cardiac output (PiCCO) was used to monitor the hemodynamic changes, including heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), cardiac index (CI), global end diastolic volume index (GEDVI), extravascular lung water index (EVLWI), maximum rate of the increase in pressure (dPmax) and systemic vascular resistance index (SVRI), for assessment of hemodynamics. According to the CI, the patients were divided into two groups , i.e. high CI group (CI ≥ 50.0 mL×s(-1)×m(-2), n = 34) and low CI group (CI characteristics of two groups were investigated. The TCM differentiation was conducted with "four syndromes and four methods", and the hemodynamic characteristics of different syndrome types were investigated, the correlation between the TCM syndrome factors and hemodynamic parameters was analyzed. The patients were divided into survival group and death group, and clinical parameters and hemodynamic characteristics were compared between two groups. The acute physiology and chronic health evaluation II (APACHEII) score and blood glucose of low CI group were higher than those of high CI group [APACHEII score: 24.4±7.2 vs. 19.8±7.4, t = -2.279, P = 0.023; blood glucose (mmol/L): 9.7 (7.7, 14.6) vs. 6.7 (5.6, 10.0), Z = -2.257, P = 0.024], CI and GEDVI were lowered [CI (mL×s(-1)×m(-2)): 36.7±8.3 vs. 68.4±16.7, t = 10.285, P = 0.000; GEDVI (mL/m(2)): 689.0 (566.0, 883.8) vs. 838.5 (692.8, 1?247.3), Z = -2.711, P = 0.007], while SVRI was increased [kPa×s×L(-1)×m(-2): 248

    Autoimmune polyendocrine syndrome type 1 (APECED) is a rare autosomal recessive disorder characterized by autoimmune multiorgan attack. The disease is caused by mutations in the autoimmune regulator gene (AIRE), resulting in defective AIRE protein, which is essential for selftolerance. Clinical manifestations are widely variable. Although the classic triad is composed by mucocutaneous candidiasis, hypoparathyroidism and adrenal failure, many other components may develop. Treatment is based on supplementation of the various deficiencies, and patients require regular follow-up throughout their lifespan. This article describes the case of a patient with the disease, and reviews literature data on the epidemiology, clinical course, immunogenetic aspects, diagnosis and treatment of the syndrome.

    Full Text Available Complex regional pain syndrome type 1 (CRPS-1 is a chronic pain syndrome characterized by severe pain, swelling, autonomic dysfunction and dystrophic changes in affected extremity. RSDS is a rare disease in children and usually occurs after trauma, however, without trauma may also occur. We were detected CRPS-1 activated by cold and stress and characterized by recurrent attacks in the bilateral upper extremities in 14 year-old girl, which is similar to Raynaud’s phenomenon. We present this case with the literature because of its rarity and atypical course.

    Records were reviewed on all patients with mucopolysaccharidosis type II (Hunter syndrome) seen at a single institution from 1999 to 2013 to identify those with a history of neonatal intensive care. Eleven of 34 patients were in a neonatal intensive care unit and all had respiratory distress with 8 diagnoses of respiratory distress syndrome and 3 of transient tachypnea of the newborn. None of the infants were premature; four were delivered by cesarean section. These findings suggest that respiratory distress is more commonly observed in neonates with MPS II than in the general population. This may reflect airway disease already present in this disorder at the time of birth. © 2013.

    Full Text Available Airway inflammation plays a major role in the pathogenesis of influenza viruses and can lead to a fatal outcome. One of the challenging objectives in the field of influenza research is the identification of the molecular bases associated to the immunopathological disorders developed during infection. While its precise function in the virus cycle is still unclear, the viral protein PB1-F2 is proposed to exert a deleterious activity within the infected host. Using an engineered recombinant virus unable to express PB1-F2 and its wild-type homolog, we analyzed and compared the pathogenicity and host response developed by the two viruses in a mouse model. We confirmed that the deletion of PB1-F2 renders the virus less virulent. The global transcriptomic analyses of the infected lungs revealed a potent impact of PB1-F2 on the response developed by the host. Thus, after two days post-infection, PB1-F2 invalidation severely decreased the number of genes activated by the host. PB1-F2 expression induced an increase in the number and level of expression of activated genes linked to cell death, inflammatory response and neutrophil chemotaxis. When generating interactive gene networks specific to PB1-F2, we identified IFN-γ as a central regulator of PB1-F2-regulated genes. The enhanced cell death of airway-recruited leukocytes was evidenced using an apoptosis assay, confirming the pro-apoptotic properties of PB1-F2. Using a NF-kB luciferase adenoviral vector, we were able to quantify in vivo the implication of NF-kB in the inflammation mediated by the influenza virus infection; we found that PB1-F2 expression intensifies the NF-kB activity. Finally, we quantified the neutrophil recruitment within the airways, and showed that this type of leukocyte is more abundant during the infection of the wild-type virus. Collectively, these data demonstrate that PB1-F2 strongly influences the early host response during IAV infection and provides new insights into the

    Metabolic syndrome as a cardiovascular disease predictor, is proposed to be reduced by following a Mediterranean diet. This study was aimed to explore the relationships between metabolic syndrome and Mediterranean diet in type 2 diabetes mellitus patients. A cross-sectional study was performed on 158 type 2 diabetes mellitus patients 28-75 years old (mean age: 54.3±9.6 yrs). Fasting glucose and lipid profile were measured. Blood pressure and anthropometric characteristics of each participant were recorded. Food frequency questionnaires were evaluated using an 11-item score to determine the adherence to Mediterranean diet. Totally, 55.4% of participants had a good adherence to Mediterranean diet. The risk of metabolic syndrome in women was significantly higher than in men (OR=8.65, CI 95%=2.88-25.99; pdiet (p=0.167). Results demonstrated no association between Mediterranean diet adherence and metabolic syndrome in type 2 diabetes mellitus patients. However, nuts, legumes and seeds might have greater benefits for diabetics. Copyright © 2016 Diabetes India. Published by Elsevier Ltd. All rights reserved.

    To investigate the prevalence and severity of subjective health complaints and describe illness perception in a population of Joint Hypermobility Syndrome or Ehlers-Danlos Syndrome-Hypermobile Type. This study was a postal survey with a questionnaire battery on demographic data, subjective health complaints inventory, and illness perception. A total of 110 individuals diagnosed with Joint Hypermobility Syndrome or Ehlers-Danlos Syndrome-Hypermobile Type from two specialized hospitals in Norway were offered participation. Further, 140 gender- and age-matched healthy controls from statistics Norway representing the general population were sent the questionnaire for reference. Overall response rate was 30.4% (n = 76), with 44.5% (n = 49) in Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome-Hypermobile Type and 19.3% (n = 27) in controls. Subjective health complaints were significantly higher in Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome-Hypermobile Type - than in the controls (32.06 vs. 11.08; p Ehlers-Danlos Syndrome-Hypermobile Type had low understanding of their illness and symptoms (understanding, mean: 3.93, SD 2.88), and reported to have moderate personal and treatment control over their illness. Adults with Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome-Hypermobile Type reported higher frequency and severity of subjective health complaints than the matched controls from the general adult population in Norway. Furthermore, Joint Hypermobility Syndrome/Ehlers-Danlos Syndrome-Hypermobile Type reported low understanding of their illness and associated symptoms, and moderate belief that their illness can be kept under control through self-management or treatment. This may indicate one of the reasons why prognosis for these patients is poor. Implications for rehabilitation Awareness of the complexity of the subjective health complaints and inquiry into illness perception could contribute with valuable information about these patients

    Objectives: To determine the frequency of metabolic syndrome in type 2 diabetes according to three commonly used operational definitions (World Health Organization(WHO), National Cholesterol Education Program Adult Treatment Panel( NCEP ATP III) and International Diabetes Federation( IDF)). To evaluate the agreement between these classifications in the Pakistani cohort. Methods: Data was collected retrospectively of 210 patients with type 2 diabetes visiting outpatient clinics of one of the large tertiary care hospitals at Karachi, Pakistan between June 2008 to November 2008. Results: The prevalence of metabolic syndrome was found to be 81.4% (WHO), 86.7 %( IDF) and 91.9 %( NCEP ATPIII). The degree of agreement (kappa statistic) was found to be highest among IDF and NCEP ATPIII (0.728) as compared to (0.436 and 0.417) between WHO and ATP and WHO and IDF respectively. The most significant predictors for metabolic syndrome were found out to be female gender OR= 8.74 95% CI 1.51-50.53, low HDL cholesterol levels OR= 0.89 95% CI 0.84-0.94 and high systolic blood pressure OR= 1.06 95% CI 1.009-1.11. Conclusion: Our study results suggested that NCEP ATPIII and IDF are the most reliable criteria for diagnosing metabolic syndrome in type 2 diabetic patients, with NECP capturing more patients in comparison to IDF definition. The alarmingly high frequency of metabolic syndrome in type 2 diabetes found in this study suggests that primary prevention strategies should be initiated earlier and early in this ethnic group and our health care system should be geared up to cope with this deadly quartet.

    Full Text Available Introduction: Multiple endocrine neoplasia type IIa (MEN IIa is an autosomal dominant syn-drome characterized bypheochromocytoma ,medullary thyroid carcinoma and hyperparathy-roidism. Pheochromocytoma approximately occurs in 50% of patients with MEN IIa. This tumor has the capacity to produce ACTH ectopically and becomes manifest like Cushing syndrome,although it is very rare. Case Report: We report a 26-year-old woman patient with severe muscle weakness, skin le-sions in extremity, hypertension, new onset diabetes and in the laboratory data hypokalemia, metabolic alkalosis, high serum level of cortisol, metanephrine, normetanephrine, calcitonin and bilateral adrenal mass in computed tomography as the first clinical manifestations of an ACTH-secreting pheochromocytoma. Conclusion: In the patients with hypertension, new onset diabetes and hypokalemia Cushing syndrome and pheochromocytoma should always be ruled out. (Sci J Hamadan Univ Med Sci 2013; 20 (3:260-265

    Autoimmune polyglandular syndromes are rare autoimmune endocrinopathies that are associated with nonendocrine autoimmunopathies. Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), also named autoimmune polyglandular syndrome type 1 (APS-1), is distinguished from autoimmune polyglandular syndrome 2 (APS-2). Major disease components of APECED are adrenal insufficiency, hypoparathyroidism, and candidiasis. The diagnosis is established by the presence of two out of the three components. Minor clinical features include autoimmune hepatitis, which occurs in up to 20% of APECED patients, and ranges from a mild to a fulminant course. The disease mostly affects juvenile patients from Sardegna, Italy, Finland, and Iran (Iranian Jews), but it also occurs in other ethnic groups. The AIRE gene responsible for APECED is expressed in cells involved in induction and maintenance of immune tolerance. Genetic alterations of the single gene are associated with APECED. Because a specific therapy is not currently available, treatment consists of hormone replacement and caring for clinical symptoms. Copyright Thieme Medical Publishers.

    Full Text Available Abstract Background Inferior conjunctivochalasis is common, but is rarely severe enough to require conjunctival excision. This report describes a patient with severe conjunctivochalasis who was subsequently diagnosed with Ehlers Danlos Syndrome, Classic Type. Case presentation A patient suffering from foreign body sensation, frequent blinking and bilateral inferior conjunctivochalasis was referred and treated by topical ocular lubrication. However, no improvement was observed prompting potential excision of conjunctivochalasis. Following patient consultation and clinical diagnosis including hypermobile joints and skin elasticity, poor wound healing and wide scar morphology, Ehlers-Danlos syndrome was confirmed in the patient. Conclusion This case highlights the need for direct patient questioning and provides the first reported association between conjunctiovochalasis and Ehlers-Danlos syndrome.

    We report a case of dragged disc syndrome associated with neurofibromatosis type II (NF2). A 5-year-old girl with amblyopia (right eye, 20/200; left eye, 20/40) presented with dragged disk syndrome and a posterior subcapsular cataract in the left eye associated with an epiretinal membrane in the right eye. Five years later, she developed exophthalmos in the right eye associated with a cervical mass. MRI revealed schwannoma developing in the left optic nerve sheath associated with a cervicothoracic schwannoma. The child was diagnosed with NF2. Association of posterior subcapsular cataract with macular epiretinal membranes is highly suggestive of NF2, although the dragged disk syndrome has not been previously reported in NF2 to our knowledge. It may also be an ocular feature of this disease.

    Recent advances in the molecular study of beta-galactosidase deficiency (GM1-gangliosidosis and Morquio syndrome type B) are reviewed. Until now, 14 different mutations have been found in the beta-galactosidase gene in patients with this disorder. Gene mutations are heterogeneous, but common and specific mutations have been identified for three types of protracted clinical course; 51Ile-->Thr mutation for Japanese adult/chronic GM1-gangliosidosis, 201Arg-->Cys for Japanese late infantile/juvenile GM1-gangliosidosis and 273Trp-->Leu for Caucasian Morquio syndrome type B. These phenotype-specific mutant genes produce mutant proteins with significant residual enzyme activity, whereas mutant proteins associated with infantile GM1-gangliosidosis patients show complete loss of enzyme activity. The phenotypic variations of this disorder may be related to different mode of intracellular processing and turnover of mutant enzyme proteins.

  15. Coherent and conventional gravidynamic quantum 1/f noise

    Handel, Peter H.; George, Thomas F.

    2008-04-01

    Quantum 1/f noise is a fundamental fluctuation of currents, physical cross sections or process rates, caused by infrared coupling of the current carriers to very low frequency (soft) quanta, also known as infraquanta. The latter are soft gravitons in the gravidynamic case with the coupling constant g= pGM2/Nch considered here -- soft photons in the electrodynamic case and soft transversal piezo-phonons in the lattice-dynamical case. Here p=3.14 and F=psi. Quantum 1/f noise is a new aspect of quantum mechanics expressed mainly through the coherent quantum 1/f effect 2g/pf derived here for large systems, and mainly through the conventional quantum 1/f effect for small systems or individual particles. Both effects are present in general, and their effects are superposed in a first approximation with the help of a coherence (weight) parameter s" that will be derived elsewhere for the gravitational case. The spectral density of fractional fluctuations S(dj/j,f) for j=e(hk/2pm)|F|2 is S(F2,f)/ = S(j,f)/2 = [4ps"/(1+s")]GM2/pfNch = 4.4 10E9 M2/(pfNgram2). Here s" = 2N'GM/c2=N'rs, where N' is the number of particles of mass M per unit length of the current, rs their Schwarzschild radius, and s" is our coherence (weight) parameter giving the ratio of coherent to conventional quantum 1/f contributions.

    Dumping syndrome is one of ten most common complications in morbidly obese patients operated. Recent studies in relation to type 2 diabetes mellitus (DM2) in patients submitted to gastric bypass led us to examine the different outcomes in this group of patients. Our objective was to determine the difference in the prevalence of dumping syndrome in patients with DM2 submitted to gastric bypass. In this retrospective study, 49 diabetic and 54 non-diabetic morbidly obese patients were submitted to gastric bypass and followed up at 3, 6, and 12 months after surgery. The occurrence of dumping was determined by the patient's medical chart, where it was considered positive if recorded in at least one of three evaluations. The 103 patients evaluated had a mean BMI of 49.5 +/- 9.3 kg/m(2) and mean age of 38 +/- 9.7 years, with 75.7% being women. The prevalence of dumping syndrome in this population was 24.3%. The prevalence of dumping was greater in patients with DM2 (44.9%) when compared to the control group (5.6%; p DM2 as the only variable associated with dumping syndrome. Dumping syndrome is a common postoperative complication in gastric bypass. Patients with DM2 show a greater postoperative prevalence of dumping.

    Full Text Available A 35-year-old widow having neurofibromatosis type 1 (NF 1 and type 1 diabetes mellitus (DM was admitted for abdominal pain, vomiting and recent onset low blood sugars. During hospitalization, the patient developed recurrent episodes of hypoglycemia despite stopping insulin. A possibility of insulinoma was made due to the presence of abdominal pain, vomiting, hypoglycemia, and association of insulinoma with NF 1. However, surprisingly c-peptide was very low and plasma insulin levels were high. A detailed psychiatric evaluation of the patient revealed Munchausen′s syndrome as a cause of recurrent hypoglycemia. Unrecognized psychiatric illnesses in type 1 DM may lead to overzealous investigation. In conclusion, the clinical presentations of persons with factitious disorder are varied and impact every area of medicine, factitious causes should always be considered in unclarified recurrent hypoglycemia, especially in cases presented with dramatic but inconsistent medical history, and an unusual personal behavior.

  19. Why is coronary collateral growth impaired in type II diabetes and the metabolic syndrome?

    Rocic, Petra

    2012-01-01

    Type II diabetes and the metabolic syndrome are strong predictors of severity of occlusive coronary disease and poorer outcomes of coronary revascularization therapies. Coronary collateral growth can provide an alternative or accessory pathway of revascularization. However, collateral growth is impaired in type II diabetes and the metabolic syndrome. Although many factors necessary for collateral growth are known and many interventions have shown promising results in animal studies, not a single attempt to induce coronary collateral growth in human clinical trials has led to satisfactory results. Accordingly, the first part of this review outlines the known deleterious effects of diabetes and the metabolic syndrome on factors necessary for collateral growth, including pro-angiogenic growth factors, endothelial function, the redox state of the coronary circulation, intracellular signaling, leukocytes and bone marrow-derived progenitors cells. The second section highlights the gaps in our current knowledge of how these factors interact with the radically altered environment of the coronary circulation in diabetes and the metabolic syndrome. The interplay between these pathologies and inadequately explored areas related to the temporal regulation of collateral remodeling and the roles of the extracellular matrix, vascular cell phenotype and pro-inflammatory cytokines are emphasized with implications to development of efficient therapies.

    Objective. To compare the serum concentration of IL-6, IL-10, TNF, IL-8, resistin, and adiponectin in type 1 diabetic patients with and without metabolic syndrome and to determine the cut-off point of the estimated glucose disposal rate that accurately differentiated these groups. Design. We conducted a cross-sectional evaluation of all patients in our type 1 diabetes clinic from January 2012 to January 2013. Patients were considered to have metabolic syndrome when they fulfilled the joint statement criteria and were evaluated for clinical, biochemical, and immunological features. Methods. We determined serum IL-6, IL-8, IL-10, and TNF with flow cytometry and adiponectin and resistin concentrations with enzyme linked immunosorbent assay in patients with and without metabolic syndrome. We also compared estimated glucose disposal rate between groups. Results. We tested 140 patients. Forty-four percent fulfilled the metabolic syndrome criteria (n = 61), 54% had central obesity, 30% had hypertriglyceridemia, 29% had hypoalphalipoproteinemia, and 19% had hypertension. We observed that resistin concentrations were higher in patients with MS. Conclusion. We found a high prevalence of MS in Mexican patients with T1D. The increased level of resistin may be related to the increased fat mass and could be involved in the development of insulin resistance. PMID:26273680

    The aim of this study was to examine the effect of Type D personality, along with other personality traits (resilience and sense of coherence), on burnout syndrome and its counterpart, engagement, among students of nursing, midwifery, and psychology. A cross-sectional study was conducted on 97 university students (91.9% females; M age = 20.2 ± 1.49 years). A Type D personality subscale, School Burnout Inventory, Utrecht Work Engagement Scale, Sense of Coherence Questionnaire, and Baruth Protective Factor Inventory were used. Linear regression models, Student's t test, and Pearson's correlation analysis were employed. Negative affectivity, a dimension of Type D personality, was a significant personality predictor for burnout syndrome (β = .54; 95% CI = [0.33, 1.01]). The only significant personality predictor of engagement was a sense of coherence. Students who were identified as having Type D personality characteristics scored significantly higher on the burnout syndrome questionnaire (t = -2.58, p burnout. © The Author(s) 2016.

    Physiotherapy plays a fundamental role in managing adults with the joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT). However, it is a challenge for both the patient and the physiotherapist as the condition is poorly understood and treatment for JHS/EDS-HT is currently undefined. Insight into current practice is, therefore, necessary in order to establish baseline knowledge in this area and in the long term to improve the standard of patient care. Therefore, the purpose of this study was to evaluate current physiotherapists' knowledge of JHS/EDS-HT and to gain insight into current physiotherapy practice with emphasis on assessment, management, and treatment efficacy. Three hundred twenty-five Flemish physiotherapists participated in the study by filling out electronically a modified version of the "Hypermobility and Hypermobility Syndrome Questionnaire" (HHQ), which covered theoretical constructs such as general knowledge, assessment, management, and learning in relation to generalized joint hypermobility and JHS/EDS-HT. The results show that physiotherapists report a low level of confidence with regard to assessment and management of JHS/EDS-HT. Knowledge of hypermobility and JHS/EDS-HT is weak, especially regarding the features associated with JHS/EDS-HT. Many treatment approaches are used by physiotherapists with the majority showing preference for education, reassurance, muscle strengthening, proprioceptive and core stability training. Almost all approaches were perceived as being clinically effective by the physiotherapists, highlighting a lack of consensus. In conclusion, this study in Flemish physiotherapists confirms that JHS/EDS-HT is under-recognized, not well known and deemed difficult to treat. Further education is required and sought by the physiotherapists surveyed, and future research is needed. © 2015 Wiley Periodicals, Inc.

    Few therapeutic modalities exist for the treatment of hepatorenal syndrome (HRS). The combination of octreotide, midodrine, and albumin has shown possible benefit in small preliminary studies in improving renal function and short-term survival. We examined the effect of octreotide, midodrine, and albumin on survival (censored for liver transplantation) and renal function in patients with HRS type 1 and type 2, compared with a historical cohort that did not receive this therapy (control group). Seventy-five patients with HRS received octreotide, midodrine, and albumin and 87 did not constitute the control group. HRS type 1 was present in 102 individuals and HRS type 2 in 60. Transplantation was performed in 45% of patients in the treatment group as compared with 26% of patients in the control group although a significant difference in transplantation rate was seen in only HRS type 2. In the treatment arm, transplant-free survival was higher compared with the control arm (median survival 101 d vs. 18 d, Pmidodrine, and albumin (P=0.0001) and HRS type 2 (P=0.05) were independently associated with improved survival. Renal function was significantly improved at 1 month (glomerular filtration rate 48 mL/min) in the treatment group compared with the control group (34 mL/min), P=0.03. The therapeutic regimen of octreotide, midodrine, and albumin significantly improved short-term survival and renal function in both HRS type 1 and type 2. This may provide a significant benefit as a bridge to liver transplantation in HRS type 1 and may prevent progression of HRS type 2 to HRS type 1.

    Although the musculoskeletal injuries associated with break-dancing which is gaining more popularity among adolescent and young people has been reported, the report regarding a peripheral nerve injury associated with breakdance is scarce. We report a rare case of a young amateur break-dancer, 'b-boy' who suffered from a painful paresthesia in his left hand, later diagnosed as type III Guyon's canal syndrome. A 23-year-old, right handed college man presented with a tenderness over the left hypothenar eminence and painful paresthesia over the ring and little fingers of 3 months duration. He trained himself as an amateur 'b boy' break-dancer for the last 10 months. Conservative management under the diagnosis of wrist sprain before presentation did not improve his hand pain. An magnetic resonance imaging and electrodiagnostic study revealed that painful paresthesia was caused by type III Guyon's canal syndrome, and 4 weeks of corticosteroid treatment was given with resolution of pain and paresthesia.

    Full Text Available Ehlers-Danlos syndrome hypermobility type a. k. a. joint hypermobility syndrome (JHS/EDS-HT is a hereditary musculoskeletal disorder associating generalized joint hypermobility with chronic pain. Anecdotal reports suggest a prominent role for kinesiophobia in disease manifestations, but no study has systematically addressed this point. Objective. To investigate the impact of kinesiophobia and its relationship with pain, fatigue, and quality of life in JHS/EDS-HT. Design. Cross-sectional study. Subjects/Patients. 42 patients (40 female and 2 male with JHS/EDS-HT diagnosis following standardized diagnostic criteria were selected. Methods. Disease features were analyzed by means of specific questionnaires and scales evaluating kinesiophobia, pain, fatigue, and quality of life. The relationships among variables were investigated using the Spearman bivariate analysis. Results. Kinesiophobia resulted predominantly in the patients’ sample. The values of kinesiophobia did not correlate with intensity of pain, quality of life, and (or the single component of fatigue. A strong correlation was discovered between kinesiophobia and general severity of fatigue. Conclusions. In JHS/EDS-HT, the onset of pain-avoiding strategies is related to the presence of pain but not to its intensity. The clear-cut correlation between kinesiophobia and severity of fatigue suggests a direct link between musculoskeletal pain and fatigue. In JHS/EDS-HT, the underlying mechanism is likely to be facilitated by primary disease characteristics, including hypotonia.

    Baraitser-Winter syndrome (BRWS) is a rare condition affecting the development of the brain and the face. The most common characteristics are unusual facial appearance including hypertelorism and ptosis, ocular colobomas, hearing loss, impaired neuronal migration and intellectual disability. BRWS is caused by mutations in the ACTB and ACTG1 genes. Cerebro-fronto-facial syndrome (CFFS) is a clinically heterogeneous condition with distinct facial dysmorphism, and brain abnormalities. Three subtypes are identified. We report a female infant with striking facial features and brain anomalies (included polymicrogyria) that fit into the spectrum of the CFFS type 3 (CFFS3). She also had minor anomalies on her hands and feet, heart and kidney malformations, and recurrent infections. DNA investigations revealed c.586C>T mutation (p.Arg196Cys) in ACTB. This mutation places this patient in the spectrum of BRWS. The same mutation has been detected in a polymicrogyric patient reported previously in literature. We expand the malformation spectrum of BRWS/CFFS3, and present preliminary findings for phenotype-genotype correlation in this spectrum. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    A coulometric titration at constant current has been devised for Nb in 1F sulfuric acid. The titration was based on the oxidation of Nb(III) to Nb(V) by Fe(III) electrogenerated at a graphite anode. Both potentiometric and amperometric end points were used. The Nb(V) was prior reduced at a mercury cathode by exhaustive electrolysis at a current density of 15 ma/mc 2 for at least 10 hr. Ta,V,Ti and a working platinum anode interfered, but the separation of the potentials of Nb(V)/Nb(III) and Ti(IV)/Ti(III) permitted the titration of first Nb and then Ti. The average error for the titration of 0.30 to 13.00 mg of niobium in 100 ml of 1F sulfuric acid was + 0.57%. (author)

    Work on nonequilibrium flicker-noise (1/f γ noise or NEFN) in conducting films of various materials and in thin-film contacts is reviewed. Experimental methods for studying nonequilibrium flicker fluctuations by separating NEFN from the total noise are suggested. Published results on NEFN in metal and alloy films, Ni/Cr-film and Ta x N y -film resistors, and contacts are systematized. It is shown that various kinds of NEFN occur in conducting films. Depending on test conditions, external influences, and the film microstructure, both stationary and non-stationary NEFNs are observed. The use of 1/f γ noise measurements for nondestructively controlling the quality of thin-film conductors is substantiated. For most of the passive IC components (thin-film conductors, resistive layers, contacts), NEFN makes a much more informative quality indicator than equilibrium flicker-noise.

    Abstract Current nutritional approaches to metabolic syndrome and type 2 diabetes generally rely on reductions in dietary fat. The success of such approaches has been limited and therapy more generally relies on pharmacology. The argument is made that a re-evaluation of the role of carbohydrate restriction, the historical and intuitive approach to the problem, may provide an alternative and possibly superior dietary strategy. The rationale is that carbohydrate restriction improves glycemic co...

    2013-08-01

    Low-frequency noise with a spectral density that depends inversely on frequency has been observed in a wide variety of systems including current fluctuations in resistors, intensity fluctuations in music and signals in human cognition. In electronics, the phenomenon, which is known as 1/f noise, flicker noise or excess noise, hampers the operation of numerous devices and circuits, and can be a significant impediment to the development of practical applications from new materials. Graphene offers unique opportunities for studying 1/f noise because of its two-dimensional structure and widely tunable two-dimensional carrier concentration. The creation of practical graphene-based devices will also depend on our ability to understand and control the low-frequency noise in this material system. Here, the characteristic features of 1/f noise in graphene and few-layer graphene are reviewed, and the implications of such noise for the development of graphene-based electronics including high-frequency devices and sensors are examined.

    The relationship between elevated serum uric acid level and metabolic syndrome (MS) has been debated. There is no data concerning this relation in Iranian population-based studies. The aim of this study was to determine the prevalence of hyperuricamia and its association with MS in type 2 diabetes mellitus (DM). This was a cross- sectional study in 1978 diabetic patients. Hyperuricamia was defined as uric acid ≥ 7 and ≥ 5.5 mg/dl for men and women respectively. Diagnosis of metabolic syndrome was based on ATPIII criteria. Clinical and biochemical parameters in hyperuricaemic and normouricaemic patients compared with other. The prevalence of hyperuricaemia and metabolic syndrome was 12.7% and 65.5% respectively. The prevalence of MS significantly increased in the highest quartile of uric acid levels compared with lowest quartile (74.4% vs 55.9%, puric acid had positive association with cholesterol, triglyceride, non-HDL cholesterol and a negative association with fasting blood sugar (FBS), glycosylated hemoglobin (HbA1C) and HDL cholesterol. Possible independent biochemical predictors of hyperuricamia were cholesterol, triglyceride, creatnine and FBS. The prevalence of MS and its components increases with increasing levels of uric acid in type 2 diabetes. Regular assessment of uric acid could give information for predicting of MS and prevention of atherosclerosis in type 2 diabetes.

    To examine whether the use of Sasang constitutional (SC) types, such as Tae-yang (TY), Tae-eum (TE), So-yang (SY), and So-eum (SE) types, increases the accuracy of risk prediction for metabolic syndrome. From 2001 to 2014, 3529 individuals aged 40 to 69 years participated in a longitudinal prospective cohort. The Cox proportional hazard model was utilized to predict the risk of developing metabolic syndrome. During the 14 year follow-up, 1591 incident events of metabolic syndrome were observed. Individuals with TE type had higher body mass indexes and waist circumferences than individuals with SY and SE types. The risk of developing metabolic syndrome was the highest among individuals with the TE type, followed by the SY type and the SE type. When the prediction risk models for incident metabolic syndrome were compared, the area under the curve for the model using SC types was significantly increased to 0.8173. Significant predictors for incident metabolic syndrome were different according to the SC types. For individuals with the TE type, the significant predictors were age, sex, body mass index (BMI), education, smoking, drinking, fasting glucose level, high-density lipoprotein (HDL) cholesterol level, systolic and diastolic blood pressure, and triglyceride level. For Individuals with the SE type, the predictors were sex, smoking, fasting glucose, HDL cholesterol level, systolic and diastolic blood pressure, and triglyceride level, while the predictors in individuals with the SY type were age, sex, BMI, smoking, drinking, total cholesterol level, fasting glucose level, HDL cholesterol level, systolic and diastolic blood pressure, and triglyceride level. In this prospective cohort study among 3529 individuals, we observed that utilizing the SC types significantly increased the accuracy of the risk prediction for the development of metabolic syndrome.

    Full Text Available The prevalence of the metabolic syndrome is rising worldwide. Its association with alcohol intake, a major lifestyle factor, is unclear, particularly with respect to the influence of drinking with as opposed to outside of meals. We investigated the associations of different aspects of alcohol consumption with the metabolic syndrome and its components. In cross-sectional analyses of 14,375 active or retired civil servants (aged 35-74 years participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil, we fitted logistic regression models to investigate interactions between the quantity of alcohol, the timing of its consumption with respect to meals, and the predominant beverage type in the association of alcohol consumption with the metabolic syndrome. In analyses adjusted for age, sex, educational level, income, socioeconomic status, ethnicity, smoking, body mass index, and physical activity, light consumption of alcoholic beverages with meals was inversely associated with the metabolic syndrome (≤4 drinks/week: OR = 0.85, 95%CI 0.74-0.97; 4 to 7 drinks/week: OR = 0.75, 95%CI 0.61-0.92, compared to abstention/occasional drinking. On the other hand, greater consumption of alcohol consumed outside of meals was significantly associated with the metabolic syndrome (7 to 14 drinks/week: OR = 1.32, 95%CI 1.11-1.57; ≥14 drinks/week: OR = 1.60, 95%CI 1.29-1.98. Drinking predominantly wine, which occurred mostly with meals, was significantly related to a lower syndrome prevalence; drinking predominantly beer, most notably when outside of meals and in larger quantity, was frequently associated with a greater prevalence. In conclusion, the alcohol-metabolic syndrome association differs markedly depending on the relationship of intake to meals. Beverage preference-wine or beer-appears to underlie at least part of this difference. Notably, most alcohol was consumed in metabolically unfavorable type and timing. If further investigations

    Interest in understanding the interplay between noise and the response of a nonlinear device cuts across disciplinary boundaries. It is as relevant for unmasking the dynamics of neurons in noisy environments as it is for designing reliable nanoscale logic circuit elements and sensors. Most studies of noise in nonlinear devices are limited to either time-correlated noise with a Lorentzian spectrum (of which the white noise is a limiting case) or just white noise. We use analytical theory and numerical simulations to study the impact of the more ubiquitous "natural" noise with a 1/f frequency spectrum. Specifically, we study the impact of the 1/f noise on a leaky integrate and fire model of a neuron. The impact of noise is considered on two quantities of interest to neuron function: The spike count Fano factor and the speed of neuron response to a small steplike stimulus. For the perfect (nonleaky) integrate and fire model, we show that the Fano factor can be expressed as an integral over noise spectrum weighted by a (low-pass) filter function given by F(t,f)=sinc(2)(πft). This result elucidates the connection between low-frequency noise and disorder in neuron dynamics. Under 1/f noise, spike dynamics lacks a characteristic correlation time, inducing the leaky and nonleaky models, to exhibit nonergodic behavior and the Fano factor, increasing logarithmically as a function of time. We compare our results to experimental data of single neurons in vivo [Teich, Heneghan, Lowen, Ozaki, and Kaplan, J. Opt. Soc. Am. A 14, 529 (1997)] and show how the 1/f noise model provides much better agreement than the usual approximations based on Lorentzian noise. The low-frequency noise, however, complicates the case for an information-coding scheme based on interspike intervals by introducing variability in the neuron response time. On a positive note, the neuron response time to a step stimulus is, remarkably, nearly optimal in the presence of 1/f noise. An explanation of this

    Data on outcomes after Stanford type A aortic dissection in patients with Marfan syndrome are limited. We investigated the primary surgery and long-term results in patients with Marfan syndrome who suffered aortic dissection. Among 1324 consecutive patients with aortic dissection type A, 74 with Marfan syndrome (58% men; median age, 37 years [first and third quartiles, 29 and 48 years]) underwent surgical repair (85% acute dissections; 68% DeBakey I; 55% composite valved graft, 30% supracoronary ascending replacement, 15% valve-sparing aortic root replacement; 12% total arch replacement; 3% in-hospital mortality) at 2 tertiary centers in the United States and Europe over the past 25 years. The rate of aortic reintervention with resternotomy was 24% (18 of 74) and of descending aorta (thoracic+abdominal) intervention was 30% (22 of 74) at a median follow-up of 8.4 years (first and third quartiles, 2.2 and 12.7 years). Freedom from need for aortic root reoperation in patients who underwent primarily a composite valved graft or valve-sparing aortic root replacement procedure was 95±3%, 88±5%, and 79±5% and in patients who underwent supracoronary ascending replacement was 83±9%, 60±13%, 20±16% at 5, 10, and 20 years. Secondary aortic arch surgery was necessary only in patients with initial hemi-arch replacement. Emergency surgery for type A dissection in patients with Marfan syndrome is associated with low in-hospital mortality. Failure to extend the primary surgery to aortic root or arch repair leads to a highly complex clinical course. Aortic root replacement or repair is highly recommended because supracoronary ascending replacement is associated with a high need (>40%) for root reintervention.

    To observe the therapeutic efficacy of Chinese medical syndrome typing and treatment combined cold needle puncture drainage operation or unipolar electrocoagulation drilling technique under laparoscope for treating clomiphene-resistant polycystic ovary syndrome (PCOS). Forty infertility patients with clomiphene-resistant PCOS were assigned to two groups using stratified random sampling method according to age, infertility time, and body mass index, 20 in each group. Patients in Group A were treated with Chinese medical syndrome typing and treatment combined cold needle puncture drainage operation, while those in Group B were treated with Chinese medical syndrome typing and treatment combined unipolar electrocoagulation drilling technique. After operation Chinese herbal treatment was administered to all patients according to syndrome typing. The serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), androgen (T), estradiol (E2), and prolactin (PRL) were determined before and after operation. The ovulation was monitored. The pregnancy rate and the pregnancy outcomes were recorded after operation. There was no statistical difference in the 3-month spontaneous ovulation rate or the 1-year pregnancy rate (P > 0.05). The levels of LH, T, and PRL were significantly lower after operation than before operation in the two groups (P typing and treatment combined cold needle puncture drainage operation or unipolar electrocoagulation drilling technique could effectively promote the ovulation. The two methods showed similar therapeutic effects.

    Waardenburg syndrome type 4 (WS4) is a rare neural crest disorder defined by the combination of Waardenburg syndrome (sensorineural hearing loss and pigmentation defects) and Hirschsprung disease (intestinal aganglionosis). Three genes are known to be involved in this syndrome, that is, EDN3 (endothelin-3), EDNRB (endothelin receptor type B), and SOX10. However, 15-35% of WS4 remains unexplained at the molecular level, suggesting that other genes could be involved and/or that mutations within known genes may have escaped previous screenings. Here, we searched for deletions within recently identified SOX10 regulatory sequences and describe the first characterization of a WS4 patient presenting with a large deletion encompassing three of these enhancers. Analysis of the breakpoint region suggests a complex rearrangement involving three Alu sequences that could be mediated by a FosTes/MMBIR replication mechanism. Taken together with recent reports, our results demonstrate that the disruption of highly conserved non-coding elements located within or at a long distance from the coding sequences of key genes can result in several neurocristopathies. This opens up new routes to the molecular dissection of neural crest disorders.

    Full Text Available Abstract Background Complex Regional Pain Syndrome type one (CRPS I or formerly Reflex Sympathetic Dystrophy (RSD is a disabling syndrome, in which a painful limb is accompanied by varying symptoms. Neuropathic pain is a prominent feature of CRPS I, and is often refractory to treatment. Since gabapentin is an anticonvulsant with a proven analgesic effect in various neuropathic pain syndromes, we sought to study the efficacy of the anticonvulsant gabapentin as treatment for pain in patients with CRPS I. Methods We did a randomized double blind placebo controlled crossover study with two three-weeks treatment periods with gabapentin and placebo separated by a two-weeks washout period. Patients started at random with gabapentin or placebo, which was administered in identical capsules three times daily. We included 58 patients with CRPS type 1. Results Patients reported significant pain relief in favor of gabapentin in the first period. Therapy effect in the second period was less; finally resulting in no significant effect combining results of both periods. The CRPS patients had sensory deficits at baseline. We found that this sensory deficit was significantly reversed in gabapentin users in comparison to placebo users. Conclusions Gabapentin had a mild effect on pain in CRPS I. It significantly reduced the sensory deficit in the affected limb. A subpopulation of CRPS patients may benefit from gabapentin.

    A mechanistic cause for Mauriac syndrome, a syndrome of growth failure and delayed puberty associated with massive liver enlargement from glycogen deposition in children with poorly controlled type 1 diabetes, is unknown. We discovered a mutation in the catalytic subunit of liver glycogen phosphorylase kinase in a patient with Mauriac syndrome whose liver extended into his pelvis. Glycogen phosphorylase kinase activates glycogen phosphorylase, the enzyme that catalyzes the first step in glycogen breakdown. We show that the mutant subunit acts in a dominant manner to completely inhibit glycogen phosphorylase kinase enzyme activity and that this interferes with glycogenolysis causing increased levels of glycogen in human liver cells. It is known that even normal blood glucose levels physiologically inhibit glycogen phosphorylase to diminish glucose release from the liver when glycogenolysis is not needed. The patient's mother possessed the same mutant glycogen phosphorylase kinase subunit, but did not have diabetes or hepatomegaly. His father had childhood type 1 diabetes in poor glycemic control, but lacked the mutation and had neither hepatomegaly nor growth failure. This case proves that the effect of a mutant enzyme of glycogen metabolism can combine with hyperglycemia to directly hyperinhibit glycogen phosphorylase, in turn blocking glycogenolysis causing the massive liver in Mauriac disease. © 2016 by the American Diabetes Association.

    Shah-Waardenburg syndrome or Waardenburg syndrome type 4 (WS4) is a neurocristopathy characterized by the association of deafness, depigmentation and Hirschsprung disease. Three disease-causing genes have been identified so far for WS4: EDNRB, EDN3, and SOX10. SOX10 mutations, found in 45-55% of WS4 patients, are inherited in autosomal dominant way. In addition, mutations in SOX10 are also responsible for an extended syndrome involving peripheral and central neurological phenotypes, referred to as PCWH (peripheral demyelinating neuropathy, central dysmyelinating leucodystrophy, Waardenburg syndrome, Hirschsprung disease). Such mutations are mostly private, and a high intra- and inter-familial variability exists. In this report, we present a patient with WS4 and a second with PCWH due to SOX10 mutations supporting again the genetic and phenotypic heterogeneity of these syndromes. Interestingly, the WS4 family carries an insertion of 19 nucleotides in exon 5 of SOX10, which results in distinct phenotypes along three different generations: hypopigmentation in the maternal grandmother, hearing loss in the mother, and WS4 in the proband. Since mosaicism cannot explain the three different related-WS features observed in this family, we propose as the most plausible explanation the existence of additional molecular events, acting in an additive or multiplicative fashion, in genes or regulatory regions unidentified so far. On the other hand, the PCWH case was due to a de novo deletion in exon 5 of the gene. Efforts should be devoted to unravel the mechanisms underlying the intrafamilial phenotypic variability observed in the families affected, and to identify new genes responsible for the still unsolved WS4 cases. © 2013 Wiley Periodicals, Inc.

  14. Dietary carbohydrate restriction in type 2 diabetes mellitus and metabolic syndrome: time for a critical appraisal

    2008-04-01

    Full Text Available Abstract Current nutritional approaches to metabolic syndrome and type 2 diabetes generally rely on reductions in dietary fat. The success of such approaches has been limited and therapy more generally relies on pharmacology. The argument is made that a re-evaluation of the role of carbohydrate restriction, the historical and intuitive approach to the problem, may provide an alternative and possibly superior dietary strategy. The rationale is that carbohydrate restriction improves glycemic control and reduces insulin fluctuations which are primary targets. Experiments are summarized showing that carbohydrate-restricted diets are at least as effective for weight loss as low-fat diets and that substitution of fat for carbohydrate is generally beneficial for risk of cardiovascular disease. These beneficial effects of carbohydrate restriction do not require weight loss. Finally, the point is reiterated that carbohydrate restriction improves all of the features of metabolic syndrome.

    Full Text Available Oral-facial-digital syndrome (OFD is a collective term describing thirteen distinctive, rare genetic disorders based on inheritance pattern and phenotypic expression. OFD is characterized by malformations of the oral cavity, the maxillofacial region and the arms and legs. Central nervous system anomalies, include intracerebral cysts, agenesis of the corpus callosum, hydrocephalus, cerebral/cerebellar atrophy, and berry aneurysms. Some degree of compromised intellectual ability and speech are present in affected individuals that correlate with the degree of central nervous system involvement. Furthermore, renal involvement in the form of polycystic kidney disease is evident in affected individuals in adulthood. In this article, we present a 37-year-old female patient that presented to the Rutgers School of Dental Medicine with oral-facial-digital syndrome, type 1.

    2011-01-01

    Wolfram syndrome (also known as DIDMOAD = diabetes insipidus, diabetes mellitus, optic atrophy, deafness) is an autosomal recessive disorder characterized by the association of childhood non-immune insulin-dependent diabetes mellitus (DM) with progressive bilateral optic atrophy. Additional symptoms including signs of severe neurodegeneration and psychiatric illness are likely to evolve over time resulting in premature death. We report on two siblings of Turkish origin from our diabetes clinic who were diagnosed with Wolfram syndrome after 6 years and 2 years duration of DM, respectively. Subtle symptoms such as attitude changes, growing reading difficulties in the history of children or adolescents with antibody negative and ketone negative DM should alert the treating physician and lead to re-evaluation of the diagnosis, keeping in mind that not all juvenile DM is type 1 DM.

    Full Text Available Background: Collagen is the major protein component of the vessels. Collagen type IV is found exclusively in the basal membrane and doesn’t form individual fibers, but instead is presented as a polygonal amorphous matrix that is associated with laminin and other matrix macromolecules to form the unique matrix basal membrane. Under the influence of the risk factors characterizing the metabolic syndrome, a variety of basal memrane degrading enzymes are activated. This leads to an early changes in vascular wall and accelerates the vascular aging The early manifestation of the metabolic syndrome in younger people in the modern society, leads to earlier manifestation of the complications of early vessels aging. Loss of elasticity is a key component in the pathogenesis of cardiovascular complications. Materials and methods: A study is conducted on 62 subjects with metabolic syndrome without vascular complications and 42 controls. The main objective of the study was to compare the imunological markers of Collagen typr IV degradation in both groups and to assess their relationship with the risk factors characterizing the metabolic syndrome. Results: When comparing the levels of Anti Coll IV Ab IgG in the control group and subjects with metabolic syndrome (respectively 0.28 + / - 0.08 and 0.40 + / - 0.11 a statistically significantly higher levels of Anti Coll IV Ab IgG were determined in the group with metabolic syndrome, F = 30.299, p = 0.000, In the whole sample Anti Col IV Ab IgG showed negative correlation with HDL with a correlation Spearman coefficient r = 0,26, and p = 0,02. The antibodies showed positive correlation with the diastolic pressure (DP, blood sugar (Gluc, total cholesterol (Tchol, triglycerides (Tg and LDL. The positive corelations were with Pearson correlation coefficient as follows: DP - r = 0,22, p = 0,04; Gluc – r=0,27, p=0,01; TChol – r=0,30, p=0.005; Tg – r=0,34, p=0,002; LDL – r=0,32, p=0,002.

    Annoying snore is the principle symptom and problem in obstructive sleep apnea syndrome (OSAS). However, investigation has been hampered by the complex snoring sound analyses. This study was aimed to investigate the energy types of the full-night snoring sounds in patients with OSAS. Twenty male OSAS patients underwent snoring sound recording throughout 6 hours of in-lab overnight polysomnogragphy. Snoring sounds were processed and analyzed by a new sound analytic program, named as Snore Map®. We transformed the 6-hour snoring sound power spectra into the energy spectrum and classified it as snore map type 1 (monosyllabic low-frequency snore), type 2 (duplex low-&mid-frequency snore), type 3 (duplex low- & high-frequency snore), and type 4 (triplex low-, mid-, & high-frequency snore). The interrator and test-retest reliabilities of snore map typing were assessed. The snore map types and their associations among demographic data, subjective snoring questionnaires, and polysomnographic parameters were explored. The interrator reliability of snore map typing were almost perfect (κ = 0.87) and the test-retest reliability was high (r = 0.71). The snore map type was proportional to the body mass index (r = 0.63, P = 0.003) and neck circumference (r = 0.52, P = 0.018). Snore map types were unrelated to subjective snoring questionnaire scores (All P>0.05). After adjustment for body mass index and neck circumference, snore map type 3-4 was significantly associated with severity of OSAS (r = 0.52, P = 0.026). Snore map typing of a full-night energy spectrum is feasible and reliable. The presence of a higher snore map type is a warning sign of severe OSAS and indicated priority OSAS management. Future studies are warranted to evaluate whether snore map type can be used to discriminate OSAS from primary snoring and whether it is affected by OSAS management.

    The power spectrum of the {delta}{sub n} statistic of quantum spectra presents 1/f{sup {alpha}} noise. For chaotic systems {alpha} = 1 while for regular systems {alpha} = 2. Although the transition from regularity to chaos is non universal, for a wide variety of systems with a mixed phase space the value of {alpha} is intermediate between 1 and 2 and can be related to the fraction of regular or chaotic orbits in the total phase space. This statistic can be a very useful tool for the analysis of experimental spectra, specially in the case of missing levels or spectral sequences with mixed symmetries.

    Joint hypermobility syndrome (JHS) and Ehlers-Danlos syndrome, hypermobility type (EDS-HT) are two overlapping heritable disorders (JHS/EDS-HT) recognized by separated sets of diagnostic criteria and still lack a confirmatory test. This descriptive research was aimed at better characterizing the clinical phenotype of JHS/EDS-HT with focus on available diagnostic criteria, and in order to propose novel features and assessment strategies. One hundred and eighty-nine (163 females, 26 males; age: 2-73 years) patients from two Italian reference centers were investigated for Beighton score, range of motion in 21 additional joints, rate and sites of dislocations and sprains, recurrent soft-tissue injuries, tendon and muscle ruptures, body mass index, arm span/height ratio, wrist and thumb signs, and 12 additional orthopedic features. Rough rates were compared by age, sex, and handedness with a series of parametric and non-parametric tools. Multiple correspondence analysis was carried out for possible co-segregations of features. Beighton score and hypermobility at other joints were influenced by age at diagnosis. Rate and sites of joint instability complications did not vary according to age at diagnosis except for soft-tissue injuries. No major difference was registered by sex and dominant versus non-dominant body side. At multiple correspondence analysis, selected features tend to co-segregate in a dichotomous distribution. Dolichostenomelia and arachnodactyly segregated independently. This study pointed out a more protean musculoskeletal phenotype than previously considered according to available diagnostic criteria for JHS/EDS-HT. Our findings corroborated the need for a re-thinking of JHS/EDS-HT on clinical grounds in order to find better therapeutic and research strategies. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Joint hypermobility syndrome/Ehlers–Danlos syndrome hypermobility type (JHS/EDS-HT), is likely the most common systemic heritable connective tissue disorder, and is mostly recognized by generalized joint hypermobility, joint instability complications, minor skin changes and a wide range of satellite features. JHS/EDS-HT is considered an autosomal dominant trait but is still without a defined molecular basis. The absence of (a) causative gene(s) for JHS/EDS-HT is likely attributable to marked genetic heterogeneity and/or interaction of multiple loci. In order to help in deciphering such a complex molecular background, we carried out a comprehensive immunofluorescence analysis and gene expression profiling in cultured skin fibroblasts from five women affected with JHS/EDS-HT. Protein study revealed disarray of several matrix structural components such as fibrillins, tenascins, elastin, collagens, fibronectin, and their integrin receptors. Transcriptome analysis indicated perturbation of different signaling cascades that are required for homeostatic regulation either during development or in adult tissues as well as altered expression of several genes involved in maintenance of extracellular matrix architecture and homeostasis (e.g., SPON2, TGM2, MMP16, GPC4, SULF1), cell-cell adhesion (e.g., CDH2, CHD10, PCDH9, CLDN11, FLG, DSP), immune/inflammatory/pain responses (e.g., CFD, AQP9, COLEC12, KCNQ5, PRLR), and essential for redox balance (e.g., ADH1C, AKR1C2, AKR1C3, MAOB, GSTM5). Our findings provide a picture of the gene expression profile and dysregulated pathways in JHS/EDS-HT skin fibroblasts that correlate well with the systemic phenotype of the patients. PMID:27518164

    Lowered pressure-pain thresholds have been demonstrated in adults with Ehlers-Danlos syndrome hypermobility type (EDS-HT), but whether these findings are also present in children is unclear. Therefore, the objectives of the study were to determine whether generalized hyperalgesia is present in children with hypermobility syndrome (HMS)/EDS-HT, explore potential differences in pressure-pain thresholds between children and adults with HMS/EDS-HT, and determine the discriminative value of generalized hyperalgesia. Patients were classified in 1 of 3 groups: HMS/EDS-HT, hypermobile (Beighton score ≥4 of 9), and healthy controls. Descriptive data of age, sex, body mass index, Beighton score, skin laxity, and medication usage were collected. Generalized hyperalgesia was quantified by the average pressure-pain thresholds collected from 12 locations. Confounders collected were pain locations/intensity, fatigue, and psychological distress. Comparisons between children with HMS/EDS-HT and normative values, between children and adults with HMS/EDS-HT, and corrected confounders were analyzed with multivariate analysis of covariance. The discriminative value of generalized hyperalgesia employed to differentiate between HMS/EDS-HT, hypermobility, and controls was quantified with logistic regression. Significantly lower pressure-pain thresholds were found in children with HMS/EDS-HT compared to normative values (range -22.0% to -59.0%; P ≤ 0.05). When applying a threshold of 30.8 N/cm 2 for males and 29.0 N/cm 2 for females, the presence of generalized hyperalgesia discriminated between individuals with HMS/EDS-HT, hypermobility, and healthy controls (odds ratio 6.0). Children and adults with HMS/EDS-HT are characterized by hypermobility, chronic pain, and generalized hyperalgesia. The presence of generalized hyperalgesia may indicate involvement of the central nervous system in the development of chronic pain. © 2016, American College of Rheumatology.

    Cutaneous manifestations are a diagnostic criterion of Ehlers-Danlos syndrome, hypermobility type (EDS-HT) and joint hypermobility syndrome (JHS). These two conditions, originally considered different disorders, are now accepted as clinically indistinguishable and often segregate as a single-familial trait. EDS-HT and JHS are still exclusion diagnoses not supported by any specific laboratory test. Accuracy of clinical diagnosis is, therefore, crucial for appropriate patients' classification and management, but it is actually hampered by the low consistency of many applied criteria including the cutaneous one. We report on mucocutaneous findings in 277 patients with JHS/EDS-HT with both sexes and various ages. Sixteen objective and five anamnestic items were selected and ascertained in two specialized outpatient clinics. Feature rates were compared by sex and age by a series of statistical tools. Data were also used for a multivariate correspondence analysis with the attempt to identify non-causal associations of features depicting recognizable phenotypic clusters. Our findings identified a few differences between sexes and thus indicated an attenuated sexual dimorphism for mucocutaneous features in JHS/EDS-HT. Ten features showed significantly distinct rates at different ages and this evidence corroborated the concept of an evolving phenotype in JHS/EDS-HT also affecting the skin. Multivariate correspondence analysis identified three relatively discrete phenotypic profiles, which may represent the cutaneous counterparts of the three disease phases previously proposed for JHS/EDS-HT. These findings could be used for revising the cutaneous criterion in a future consensus for the clinical diagnosis of JHS/EDS-HT. © 2015 Wiley Periodicals, Inc.

    Patients with joint hypermobility syndrome/Ehlers-Danlos syndrome, hypermobility type (JHS/EDS-HT) commonly suffer from pain. How this hereditary connective tissue disorder causes pain remains unclear although previous studies suggested it shares similar mechanisms with neuropathic pain and fibromyalgia. In this prospective study seeking information on the mechanisms underlying pain in patients with JHS/EDS-HT, we enrolled 27 consecutive patients with this connective tissue disorder. Patients underwent a detailed clinical examination, including the neuropathic pain questionnaire DN4 and the fibromyalgia rapid screening tool. As quantitative sensory testing methods, we included thermal-pain perceptive thresholds and the wind-up ratio and recorded a standard nerve conduction study to assess non-nociceptive fibres and laser-evoked potentials, assessing nociceptive fibres. Clinical examination and diagnostic tests disclosed no somatosensory nervous system damage. Conversely, most patients suffered from widespread pain, the fibromyalgia rapid screening tool elicited positive findings, and quantitative sensory testing showed lowered cold and heat pain thresholds and an increased wind-up ratio. While the lack of somatosensory nervous system damage is incompatible with neuropathic pain as the mechanism underlying pain in JHS/EDS-HT, the lowered cold and heat pain thresholds and increased wind-up ratio imply that pain in JHS/EDS-HT might arise through central sensitization. Hence, this connective tissue disorder and fibromyalgia share similar pain mechanisms. WHAT DOES THIS STUDY ADD?: In patients with JHS/EDS-HT, the persistent nociceptive input due to joint abnormalities probably triggers central sensitization in the dorsal horn neurons and causes widespread pain. © 2016 European Pain Federation - EFIC®

    Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT) is a hereditary connective tissue disorder affecting every bodily system. It is largely underdiagnosed by many practitioners, with the result of a considerable delay in diagnosis and, consequently, in the onset of adequate management schedule and treatment. Patients may also experience to be misbelieved, erroneously considered affected by a psychiatric or psychosomatic disorders, and rejected by the medical profession, which can lead to feelings of anger and resentment. Patient journeys are often long and complicated, but if doctors allowed the patient time to tell the full story, and were more prepared to think holistically, there may be a far more positive outcome. Here, the patients' perspective is presented with a narrative medicine approach, illustrating the tri-dimensional experience of a JHS/EDS-HT patient, who is also a Bowen Practitioner and a medical writer/educator. Narrative medicine would be invaluable in working with JHS/EDS-HT so that the patient can tell the story, and offer the practitioner a whole picture of her/his suffering and, often, the key for understanding the cause(s). Once this has been achieved, it might be possible to build upon a more positive and therapeutic dialogue which would result in better treatment and more effective management. It is also important for doctors to communicate with JHS/EDS-HT experts who will ultimately improve the patient journey and treatment outcomes of such a complex connective tissue disorder. © 2015 Wiley Periodicals, Inc.

    Pseudo-TORCH syndrome (PTS) is characterized by microcephaly, enlarged ventricles, cerebral calcification, and, occasionally, by systemic features at birth resembling the sequelae of congenital infection but in the absence of an infectious agent. Genetic defects resulting in activation of type 1 interferon (IFN) responses have been documented to cause Aicardi-Goutières syndrome, which is a cause of PTS. Ubiquitin-specific peptidase 18 (USP18) is a key negative regulator of type I IFN signaling. In this study, we identified loss-of-function recessive mutations of USP18 in five PTS patients from two unrelated families. Ex vivo brain autopsy material demonstrated innate immune inflammation with calcification and polymicrogyria. In vitro, patient fibroblasts displayed severely enhanced IFN-induced inflammation, which was completely rescued by lentiviral transduction of USP18. These findings add USP18 deficiency to the list of genetic disorders collectively termed type I interferonopathies. Moreover, USP18 deficiency represents the first genetic disorder of PTS caused by dysregulation of the response to type I IFNs. Therapeutically, this places USP18 as a promising target not only for genetic but also acquired IFN-mediated CNS disorders. © 2016 Meuwissen et al.

    Full Text Available Background. Joint hypermobility syndrome/Ehlers-Danlos syndrome, hypermobility type (JHS/EDS-HT, is a hereditary connective tissue disorder mainly characterized by generalized joint hypermobility, skin texture abnormalities, and visceral and vascular dysfunctions, also comprising symptoms of autonomic dysfunction. This study aims to further evaluate cardiovascular autonomic involvement in JHS/EDS-HT by a battery of functional tests. Methods. The response to cardiovascular reflex tests comprising deep breathing, Valsalva maneuver, 30/15 ratio, handgrip test, and head-up tilt test was studied in 35 JHS/EDS-HT adults. Heart rate and blood pressure variability was also investigated by spectral analysis in comparison to age and sex healthy matched group. Results. Valsalva ratio was normal in all patients, but 37.2% of them were not able to finish the test. At tilt, 48.6% patients showed postural orthostatic tachycardia, 31.4% orthostatic intolerance, 20% normal results. Only one patient had orthostatic hypotension. Spectral analysis showed significant higher baroreflex sensitivity values at rest compared to controls. Conclusions. This study confirms the abnormal cardiovascular autonomic profile in adults with JHS/EDS-HT and found the higher baroreflex sensitivity as a potential disease marker and clue for future research.

    Waardenburg syndrome is an autosomal dominant disorder characterized by deafness and pigmentary abnormalities such as heterochromia of irides, hypopigmented skin patches, white forlock and premature graying. Clinically the syndrome has been classified into three types. Type II differs from type I in that dystopia canthorum is generally absent, and type III has associated limb anomalies. Recently linkage analysis localized the gene for WSI to chromosome 2q. PAX-3, which is a human analogue of the murine pax-3 locus, maps to this region and mutations in this gene have been found to segregate with WSI. However genetic heterogeneity clearly exists: most if not all WSII families are unlinked to PAX-3 while most if not all WSI cases are linked. We ascertained a four-year-old female child with an interstitial deletion of chromosome 13 who had features of WS including bilateral congenital sensorineural hearing loss, pale blue irides and pinched nostrils as well as hypertelorism microcephaly, bilateral eyelid ptosis, digitalization of thumbs and fifth finger clinodactyly. High resolution chromosomal analysis revealed a de novo interstitial deletion of 13q22-33.2. There was no family history of WS or retardation. A similar deletion in the region of 13q21-32 has been described in a 13-year-old boy with features of WSII. These two cases strongly suggested that this chromosomal region may include a second locus for WS. We have identified eight families with clinical features of WS type I which have been excluded from linkage to the PAX-3 locus. We have typed these families for microsatellite markers spanning chromosome 13. Linkage between WSII and the chromosome 13 markers was excluded in these families. Hirschsprung disease has been associated with WS and it has recently been mapped to chromosome 10q11.2-q21.1. We are currently typing the 8 families for microsatellites in this region.

    The most important performance parameters for a particle collider are the beam energy and the luminosity. An event is the rate of useful interactions, and it’s a very important term in particle collider world. The quantity that defines the ability of a collider to produce events is called the luminosity (L). Precise luminosity measurements are of crucial importance, as it determines the precision of any physics cross section measurement. After the first Long Shutdown (LS1) the original performance goal for the luminosity of 1 × 10 34 cm −2 s −1 was reached with 10 11 protons per bunch and bunch spacing of 25 ns. In such conditions radiation hard detectors with extremely fast response are required, especially for instrumentation near the beam. BCM1F measures separately both luminosity and machine induced background particles with an excellent time resolution. Particles originating from collisions and machine induced back- ground arrive with 12 ns time difference. The performance of the BCM1F detector is...

    The ketogenic diet is an evidence-based treatment for resistant epilepsy including Lennox-Gastaut syndrome. This diet is based on low carbohydrate-high fat intakes. Dietary treatment is also therapeutic for inborn errors of metabolism such as aminoacdiopathies. We report a child with both Lennox-Gastaut syndrome and tyrosinemia type 1. This epilepsy syndrome resulted form a porencephalic cyst secondary to brain abscesses that occurred during the management of malnutrition due to untreated tyrosinemia type 1. We used a ketogenic diet as treatment for Lennox-Gastaut syndrome taking into account dietary requirements for tyrosinemia type 1. The patient was transiently responder during a 6-month period. This report illustrates that ketogenic diet remains a therapeutic option even when additional dietary requirements are needed. Copyright © 2016 European Paediatric Neurology Society.

    The diagnosis of Brugada syndrome based on the ECG is hampered by the dynamic nature of its ECG manifestations. Brugada syndrome patients are only 25% likely to present a type 1 ECG. The objective of this study is to provide an ECG diagnostic criterion for Brugada syndrome patients that can be applied consistently even in the absence of a type 1 ECG. We recorded 67-lead body surface potential maps from 94 Brugada syndrome patients and 82 controls (including right bundle branch block patients and healthy individuals). The spatial propagation direction during the last r' wave and the slope at the end of the QRS complex were measured and compared between patients groups. Receiver-operating characteristic curves were constructed for half of the database to identify optimal cutoff values; sensitivity and specificity for these cutoff values were measured in the other half of the database. A spontaneous type 1 ECG was present in only 30% of BrS patients. An orientation in the sagittal plane syndrome with a sensitivity of 69% and a specificity of 97% in non-type 1 Brugada syndrome patients. Spatiotemporal characteristics of surface ECG recordings can enable a robust identification of BrS even without the presence of a type 1 ECG. © 2016 Wiley Periodicals, Inc.

    To determine the frequency of the metabolic syndrome in patients with type 2 diabetes mellitus wiho attended the diabetes clinic of Liaquat National Hospital, Karachi. A descriptive study was conducted at the diabetes clinic of Liaquat National Hospital from June 2004 to December 2004. We enrolled 233 subjects with type 2 diabetes mellitus. Frequency of metabolic syndrome was estimated according to the criteria proposed by National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III), with adoption of the Asian criteria for abdominal obesity and recently proposed International Diabetes Federation (IDF) diagnostic criteria for metabolic syndrome. There were 233 patients with type 2 diabetes mellitus in whom 49.8% were men and 50.2% were women. Mean age was 49.9 years. By applying NCEP-ATP III criteria, metabolic syndrome was found in 79.7% type 2 diabetics, (45.5% women and 34.3% men), by applying IDF criteria, metabolic syndrome was identified in 68.1% of type 2 diabetics (43.7% women and 24.4% men). In our study the frequency of the metabolic syndrome was found significantly high, especially in women and at a relatively young age of 49.9 years.

    Ehlers-Danlos syndrome (EDS) is a rare inherited connective disease. Among several subgroups, type IV EDS is frequently associated with spontaneous catastrophic bleeding from a vascular fragility. We report on a case of carotid-cavernous fistula (CCF) in a patient with type IV EDS. A 46-year-old female presented with an ophthalmoplegia and chemosis in the right eye. Subsequently, seizure and cerebral infarction with micro-bleeds occurred. CCF was completely occluded with transvenous coil embolization without complications. Thereafter, the patient was completely recovered. Transvenous coil embolization can be a good treatment of choice for spontaneous CCF with type IV EDS. However, every caution should be kept during invasive procedure. PMID:24653803

    Full Text Available Ehlers-Danlos syndrome (EDS is a group of connective tissue disorders which are divided into various distinguishable phenotypes. The type of EDS determines the potential obstetric complications. Due to the spectrum of clinical manifestation and overlap between phenotypes, there are no standardised obstetric management guidelines. Existing literature illustrates different obstetric management in hypermobility type of EDS, including uneventful term vaginal deliveries as well as preterm cesarean section deliveries. This paper discusses obstetric management of a woman with EDS hypermobility type. Cesarean section was deemed the most appropriate delivery method in this patient due to the possible complications including risk of joint dislocation and pain morbidity. No obstetric complications were experienced, and good maternal and neonatal outcomes were achieved.

    Human telomeric regions are packaged as constitutive heterochromatin, characterized by extensive subtelomeric DNA methylation and specific histone modifications. ICF (immunodeficiency, centromeric instability, facial anomalies) type I patients carry mutations in DNA methyltransferase 3B (DNMT3B) that methylates de novo repetitive sequences during early embryonic development. ICF type I patient fibroblasts display hypomethylated subtelomeres, abnormally short telomeres and premature senescence. In order to study the molecular mechanism by which the failure to de novo methylate subtelomeres results in accelerated telomere shortening, we generated induced pluripotent stem cells (iPSCs) from 3 ICF type I patients. Telomeres were elongated in ICF-iPSCs during reprogramming, and the senescence phenotype was abolished despite sustained subtelomeric hypomethylation and high TERRA levels. Fibroblast-like cells (FLs) isolated from differentiated ICF-iPSCs maintained abnormally high TERRA levels, and telomeres in these cells shortened at an accelerated rate, leading to early senescence, thus recapitulating the telomeric phenotype of the parental fibroblasts. These findings demonstrate that the abnormal telomere phenotype associated with subtelomeric hypomethylation is overridden in cells expressing telomerase, therefore excluding telomerase inhibition by TERRA as a central mechanism responsible for telomere shortening in ICF syndrome. The data in the current study lend support to the use of ICF-iPSCs for modeling of phenotypic and molecular defects in ICF syndrome and for unraveling the mechanism whereby subtelomeric hypomethylation is linked to accelerated telomeric loss in this syndrome. © The Author 2014.

    To determine the prevalence of binge eating disorder (BED) and night eating syndrome (NES) among applicants to the Look AHEAD (Action for Health in Diabetes) study. The Eating Disorders Examination-Questionnaire (EDE-Q) and the Night Eating Questionnaire (NEQ) were used to screen patients. Phone interviews were conducted using the EDE for those who reported at least eight episodes of objective binge eating in the past month and using the Night Eating Syndrome History and Interview for those who scored > or =25 on the NEQ. Recruitment at four sites (Birmingham, n = 200; Houston, n = 259; Minneapolis, n = 182; and Philadelphia, n = 204) yielded 845 participants (58% women; mean age = 60.1 +/- 6.7 years; mean BMI = 36.2 +/- 6.3 kg/m(2)). Screening scores were met by 47 (5.6%) applicants on the EDE-Q and 71 (8.4%) on the NEQ. Of the 85% (40/47) who completed the EDE interview, 12 were diagnosed with BED, representing 1.4% of the total sample. Of the 72% (51/71) who completed the Night Eating Syndrome History and Interview, 32 were diagnosed with NES, equal to 3.8% of the total sample. Three participants had both BED and NES. Participants with eating disorders were younger, heavier, and reported more eating pathology than those without eating disorders. Among obese adults with type 2 diabetes, NES was reported more frequently than BED, which, in turn, was less common than expected.

    The aim of this study is to determine the relationships of vitamin D with diabetes, insulin resistance obesity, and metabolic syndrome. Intra cellular vitamin D receptors and the 1-α hydroxylase enzyme are distributed ubiquitously in all tissues suggesting a multitude of functions of vitamin D. It plays an indirect but an important role in carbohydrate and lipid metabolism as reflected by its association with type 2 diabetes (T2D), metabolic syndrome, insulin secretion, insulin resistance, polycystic ovarian syndrome, and obesity. Peer-reviewed papers, related to the topic were extracted using key words, from PubMed, Medline, and other research databases. Correlations of vitamin D with diabetes, insulin resistance and metabolic syndrome were examined for this evidence-based review. In addition to the well-studied musculoskeletal effects, vitamin D decreases the insulin resistance, severity of T2D, prediabetes, metabolic syndrome, inflammation, and autoimmunity. Vitamin D exerts autocrine and paracrine effects such as direct intra-cellular effects via its receptors and the local production of 1,25(OH) 2 D 3 , especially in muscle and pancreatic β-cells. It also regulates calcium homeostasis and calcium flux through cell membranes, and activation of a cascade of key enzymes and cofactors associated with metabolic pathways. Cross-sectional, observational, and ecological studies reported inverse correlations between vitamin D status with hyperglycemia and glycemic control in patients with T2D, decrease the rate of conversion of prediabetes to diabetes, and obesity. However, no firm conclusions can be drawn from current studies, because (A) studies were underpowered; (B) few were designed for glycemic outcomes, (C) the minimum (or median) serum 25(OH) D levels achieved are not measured or reported; (D) most did not report the use of diabetes medications; (E) some trials used too little (F) others used too large, unphysiological and infrequent doses of vitamin D; and

    Full Text Available We report a case of autoimmune polyglandular syndrome type 1 (APS1 complicated by severe vascular insufficiency due to diffuse vascular calcification. APS1 is characterised clinically by multiple autoimmune conditions and development of at least two components of the triad of mucocutaneous candidiasis, hypoparathyroidism, and autoimmune adrenal insufficiency. We highlight the problems in current serum calcium monitoring methods and suggest that fluctuations in serum calcium concentrations due to difficulties treating hypoparathyroidism may have contributed to the vascular calcification seen in this case.

    Full Text Available The aim of this study was to evaluate the association between the family history (FH of type 2 diabetes and metabolic syndrome (MetS in a group of non-diabetic obese female subjects. A cross-sectional study was conducted in 239 female patients with obesity, regularly attending the Internal Medicine Division’s outpatient clinic (Hospital de Clínicas de Porto Alegre, Brazil. The inclusion criteria were patients with body mass index ?30 kg/m2 and absence of type 2 diabetes. The FH was considered positive if a first degree relative had a diagnosis of diabetes. Seventy-four of 239 patients evaluated (30% had a positive FH for type 2 diabetes. Patients with positive FH had higher waist/hip ratio and MetS more often than patients with negative FH. FH of type 2 diabetes was associated with MetS in this sample of non-diabetic obese female patients. Waist/hip ratio and fasting plasma glucose, markers of insulin resistance, were also associated with FH of type 2 diabetes. The simple question: “Do you have a FH of type 2 diabetes?” may help to identify the obese patients that should be better evaluated and intensively treated with the objective of preventing type 2 diabetes.

    The purpose of the study was investigation of the connective tissue metabolic features among women with menopausal syndrome (MS) and MS, in which the arthropathic syndrome is leading and comparative analysis of the connective tissue indicators exchange during menopause caused in a surgical and natural way. We examined 70 women in total, menopause duration they accounted for 1,95±1,1 years, it came both as natural, and as a result of a surgery. The main group included 40 women with MS with leading arthropathic syndrome. The patients' modified menopausal index was calculated (MMI), the functional condition of the joints was assessed on a scale-questionnaire with the calculation of the clinical-functional index of WOMAC; the quantitative content and qualitative composition of glycosaminoglycans in the serum, the urinary excretion of hydroxyproline and uronic acids were determined. To determine the degree of deviation from the control (standard) indicators was used non-parametric Mann-Whitney criterion and factor analysis (main components method). It was revealed that all patients have an increased content of glycosaminoglycans and glycoprotein in the blood, which corresponds to the general age-related rearrangement of connective tissue metabolism, but the patients of the main group have more expressed indictors, which corresponds to more severe dystrophic changes and the severity of clinical symptoms. Redistribution of the fractional composition of glycosaminoglycans towards the increase of chondroitin-6 sulfate in patients of the main group indicates the presence of pre-emptive destruction of cartilage. The arthropathic syndrome availability also confirms the significant reduction CI-6s / CI-4s ratio and an increased content of chondroitin sulfates. Patients with a natural type of menopause showed more pronounced changes in connective tissue metabolites, in contrast to patients with surgical menopause еhat indicates a longer and more invasive pathologic course of

    We report a 19-year-old man with craniofacial dysmorphic features, anorectal malformations, eye colobomas, orthopaedic anomalies, and mild neurodevelopmental delay. Cat eye syndrome (CES) was suspected, and confirmed by cytogenetic analysis which showed the presence of a supernumerary bisatellited chromosome, identified by fluorescence in situ hybridization (FISH) as invdup(22). The marker was further analyzed with six BAC clones located at the 22q11.1 and 22q11.2 regions; this analysis allowed correct assignment at low copy repeat 4 on chromosome 22 (LCR22-4) of the two breakpoints, confirming the presence of a CES chromosome type II. The patient's phenotype is considered in the light of the cytogenetic, and FISH investigations results and other patients reported in literature. Molecular definition of the breakpoints at the LCR22-4 copy confirms the role of different chromosome 22-specific LCRs in CES chromosomes generation, as well as in other chromosome 22 germ line rearrangements. Our report confirms that, unlike other conditions, i.e. the invdup(15) bisatellited dicentric marker, the CES phenotype does not appear to correlate with the size of the marker chromosome. Additional cases are necessary to be able to draw more specific genotype-phenotype correlations and to determine the outcome of patients with CES, especially when this rare condition is diagnosed in prenatal age.

    To carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD). By using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD. Based on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias. TCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.

  9. 1/f and the Earthquake Problem: Scaling constraints that facilitate operational earthquake forecasting

    yoder, M. R.; Rundle, J. B.; Turcotte, D. L.

    2012-12-01

    The difficulty of forecasting earthquakes can fundamentally be attributed to the self-similar, or "1/f", nature of seismic sequences. Specifically, the rate of occurrence of earthquakes is inversely proportional to their magnitude m, or more accurately to their scalar moment M. With respect to this "1/f problem," it can be argued that catalog selection (or equivalently, determining catalog constraints) constitutes the most significant challenge to seismicity based earthquake forecasting. Here, we address and introduce a potential solution to this most daunting problem. Specifically, we introduce a framework to constrain, or partition, an earthquake catalog (a study region) in order to resolve local seismicity. In particular, we combine Gutenberg-Richter (GR), rupture length, and Omori scaling with various empirical measurements to relate the size (spatial and temporal extents) of a study area (or bins within a study area) to the local earthquake magnitude potential - the magnitude of earthquake the region is expected to experience. From this, we introduce a new type of time dependent hazard map for which the tuning parameter space is nearly fully constrained. In a similar fashion, by combining various scaling relations and also by incorporating finite extents (rupture length, area, and duration) as constraints, we develop a method to estimate the Omori (temporal) and spatial aftershock decay parameters as a function of the parent earthquake's magnitude m. From this formulation, we develop an ETAS type model that overcomes many point-source limitations of contemporary ETAS. These models demonstrate promise with respect to earthquake forecasting applications. Moreover, the methods employed suggest a general framework whereby earthquake and other complex-system, 1/f type, problems can be constrained from scaling relations and finite extents.; Record-breaking hazard map of southern California, 2012-08-06.

    Waardenburg syndrome is a rare genetic disorder, inherited as an autosomal dominant trait. The condition is characterized by sensorineural hearing loss and pigment disturbances of the hair, skin, and iris. The de novo mutation in the SOX10 gene, responsible for Waardenburg syndrome type II, is rarely seen. The present study aimed to identify the genetic causes of Waardenburg syndrome type II in a Chinese family. Clinical and molecular evaluations were conducted in a Chinese family with Waardenburg syndrome type II. A novel SOX10 heterozygous c.259-260delCT mutation was identified. Heterozygosity was not observed in the parents and sister of the proband, indicating that the mutation has arisen de novo. The novel frameshift mutation, located in exon 3 of the SOX10 gene, disrupted normal amino acid coding from Leu87, leading to premature termination at nucleotide 396 (TGA). The high mobility group domain of SOX10 was inferred to be partially impaired. The novel heterozygous c.259-260delCT mutation in the SOX10 gene was considered to be the cause of Waardenburg syndrome in the proband. The clinical and genetic characterization of this family would help elucidate the genetic heterogeneity of SOX10 in Waardenburg syndrome type II. Moreover, the de novo pattern expanded the mutation data of SOX10. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available The influence of obesity on cardiometabolic health in the general population has been widely studied, but few studies are dealing with the problem of obesity in children and adolescents with type 1 diabetes. Aim: The aim of this study was to determine the presence of overweight, and obese persons with metabolic syndrome in children and adolescents with type 1 diabetes and to determine the conection of nutritional status with other risk factors for cardiovascular disease, such as dyslipidemia, glycoregulation, high blood pressure , insulin dose, age, illness, length of illness. Methods: The study included 197 children and adolescents with type 1 diabetes mellitus (103 females, 94 males. The average age of respondents was 12,71 years. Data on body weight, height, BMI was calculated according to the formula kg/m2. Standard laboratory procedures were determined, total cholesterol, LDL and HDL cholesterol, AST, GHbA1c, data on a daily dose of insulin, and type of insulin therapy, age at which the disease began, duration of disease, the possible existence of microvascular complications (microalbuminuria, retinopathy, neuropathy and hypertension were obtained. Results: There were 77,2% patients had normal weight, 14,2% were overweight, 3,4% were obese and 5,2% nutritional had metabolic syndrome. We found statistically significant conection between nutritional impairment and total cholesterol, tryglycerides, hypertension, length of disease and daily insuline dose. Conclusion: Due to the fact that people with type 1 diabetes are at high risk for the development of vascular complications, prevention, early detection and treatment of nutritional impairment as well as other cardiometabolic risk factors are imperative.

The estimation algorithm is derived from the least square estimation theory and designed to estimate the velocity change induced by the on-boarded thruster firing as well as the orbit parameter. The estimation results show that the Koreasat F1 thruster are in bad thruster condition of 64% performance for REA when it fires in on-pulse mode. Here, the performance is defined by the ratio of the resulted velocity change to that of planned. But, in the case of the Koreasat F2, it is found that the performance approximately reaches up to 100%, even after the 5 years of the mission.

    Waardenburg syndrome (WS) is a genetic disorder characterized by sensorineural hearing loss and pigmentation anomalies. The clinical definition of four WS types is based on additional features due to defects in structures mostly arising from the neural crest, with type I and type II being the most frequent. While type I is tightly associated to PAX3 mutations, WS type II (WS2) remains partly enigmatic with mutations in known genes (MITF, SOX10) accounting for only 30% of the cases. We performed exome sequencing in a WS2 index case and identified a heterozygous missense variation in EDNRB. Interestingly, homozygous (and very rare heterozygous) EDNRB mutations are already described in type IV WS (i.e., in association with Hirschsprung disease [HD]) and heterozygous mutations in isolated HD. Screening of a WS2 cohort led to the identification of an overall of six heterozygous EDNRB variations. Clinical phenotypes, pedigrees and molecular segregation investigations unraveled a dominant mode of inheritance with incomplete penetrance. In parallel, cellular and functional studies showed that each of the mutations impairs the subcellular localization of the receptor or induces a defective downstream signaling pathway. Based on our results, we now estimate EDNRB mutations to be responsible for 5%-6% of WS2. © 2017 Wiley Periodicals, Inc.

    To compare the duration of effect of two dosage regimes of botulinum toxin A to treat patients with Frey's syndrome. Prospective study of two unselected cohorts of 20 patients each. The dimension of the affected skin area was determined with Minors iodine-starch test. The skin was infiltrated with botulinum toxin type A (Dysport, Ipsen Pharma, Ettlingen, Germany) using an interinjection distance of 1 cm. In the first group, a concentration of 10 mount units (MU)/0.1 mL and in the second group a concentration of 20 MU/0.1 mL was used. At each injection site, 0.1 mL of the respective solution was injected. The outcome measures were the time of reappearance of gustatory sweating, and the results of an iodine-starch test 10 and 20 months after treatment. Using the lower concentration, the mean duration of effectiveness was 8.3 +/- 2 months (mean +/- standard deviation). Using the higher concentration, the effect was much longer at 16.5 +/- 6 months. Eighty-five percent of the first group but only 5% of the second had a positive Minor's iodine-starch test 10 months after treatment. After 20 months four patients in the second group still had a negative iodine-starch test. In both groups, the amount of required botulinum toxin for the second treatment after recurrence of Frey's syndrome was the same as for the first treatment. Using a higher concentration of botulinum toxin type A (20 MU Dysport/0.1 mL) is more effective than a lower concentration (10 MU Dysport/0.1 mL) in the treatment of Frey's syndrome.

    Purpose. Progressive decline of psychophysical cone-mediated measures has been reported in type 1 (USH1) and type 2 (USH2) Usher syndrome. Conventional cone electroretinogram (ERG) responses in USH demonstrate poor signal-to-noise ratio. We evaluated cone signals in USH1 and USH2 by recording microvolt level cycle-by-cycle (CxC) ERG. Methods. Responses of molecularly genotyped USH1 (n = 18) and USH2 (n = 24) subjects (age range, 15–69 years) were compared with those of controls (n = 12). A subset of USH1 (n = 9) and USH2 (n = 9) subjects was examined two to four times over 2 to 8 years. Photopic CxC ERG and conventional 30-Hz flicker ERG were recorded on the same visits. Results. Usher syndrome subjects showed considerable cone flicker ERG amplitude losses and timing phase delays (P < 0.01) compared with controls. USH1 and USH2 had similar rates of progressive logarithmic ERG amplitude decline with disease duration (−0.012 log μV/y). Of interest, ERG phase delays did not progress over time. Two USH1C subjects retained normal response timing despite reduced amplitudes. The CxC ERG method provided reliable responses in all subjects, whereas conventional ERG was undetectable in 7 of 42 subjects. Conclusions. Cycle-by-cycle ERG showed progressive loss of amplitude in both USH1 and USH2 subjects, comparable to that reported with psychophysical measures. Usher subjects showed abnormal ERG response latency, but this changed less than amplitude with time. In USH syndrome, CxC ERG is more sensitive than conventional ERG and warrants consideration as an outcome measure in USH treatment trials. PMID:25425308

    Waardenburg syndrome (WS) characterized by sensorineural hearing loss and pigmentary abnormalities is genetically heterogeneous and phenotypically variable. This study investigated the molecular etiology and genotype-phenotype correlation of WS in 36 Chinese Han deaf probands and 16 additional family members that were clinically diagnosed with WS type I (WS1, n = 8) and type II (WS2, n = 42). Mutation screening of six WS-associated genes detected PAX3 mutations in 6 (86%) of the 7 WS1 probands. Among the 29 WS2 probands, 13 (45%) and 10 (34%) were identified with SOX10 and MITF mutations, respectively. Nineteen of the 26 detected mutations were novel. In WS2 probands whose parental DNA samples were available, de novo mutations were frequently seen for SOX10 mutations (7/8) but not for MITF mutations (0/5, P = 0.005). Excessive freckle, a common feature of WS2 in Chinese Hans, was frequent in WS2 probands with MITF mutations (7/10) but not in those with SOX10 mutations (0/13, P = 4.9 × 10−4). Our results showed that mutations in SOX10 and MITF are two major causes for deafness associated with WS2. These two subtypes of WS2 can be distinguished by the high de novo rate of the SOX10 mutations and the excessive freckle phenotype exclusively associated with the MITF mutations. PMID:27759048

    Serum uric acid (SUA) has been suggested as a potentially modifiable mediator associated with the metabolic syndrome. Hyperuricemia and metabolic syndrome were both associated with adverse renal outcome. However, epidemiologic data are limited regarding this relationship in patients with type 2 diabetes mellitus (T2DM). This study aims to determine whether elevated SUA is associated with an increased prevalence of metabolic risk factors, albuminuria, and chronic kidney disease (CKD) in a large sample of patients with T2DM. It also examines the combined effect of SUA and metabolic syndrome components on the odds of CKD. A total of 1463 patients with T2DM were recruited. Blood samples were obtained to measure metabolic parameters. Patients with macroalbuminuria or an estimated glomerular filtration rate of metabolic syndrome, central obesity, hypertension, high triglycerides (TGs), CKD, and macroalbuminuria was significantly higher in patients with hyperuricemia than those in the lowest tertile of SUA (T1). One standard deviation (SD) increment of SUA was significantly associated with metabolic syndrome, central obesity, and high TGs after adjustment for age, sex, estimated glomerular filtration rate (eGFR), and albuminuria. The odds of CKD went up to 1.37-fold with every 1 SD increment of SUA, independent of age, sex, and components of metabolic syndrome. There was a significant, graded increase in odds of CKD by increasing SUA levels and the number of metabolic syndrome risk factors (Pmetabolic syndrome components on the odds of CKD.

    Complex regional pain syndrome (CRPS) is characterised by the presence of pain accompanied by sensory, autonomic and motor symptoms, usually preceded by a lesion or immobilisation. The clinical course is disproportionate to the initial injury in intensity and in duration. Its distribution is regional, predominantly in limbs. It is classified as type I and type II according to the absence or presence of nerve injury. We present the cases of seven children, 6 girls and 1 boy, aged 7 to 15 years. Three had a history of previous trauma. In 5 cases, the symptoms were located in the lower limbs. Time to diagnosis was between 4 and 90 days. Three patients had clinical features of anxiety and depression. Imaging and immunological studies were performed to rule out differential diagnoses in all the children. Interdisciplinary treatment was performed with physiotherapy, psychotherapy, and gabapentin or pregabalin. All patients had a good clinical outcome, with no relapses in the follow-up period (between 4 and 30 months). CRPS is frequently unrecognised in children, leading to family anxiety and unnecessary para-clinical costs. Paediatricians and paediatric neurologists should be aware of this syndrome in order to avoid delay in diagnosis, unnecessary studies, and multiple visits to specialists, with a view to providing effective treatment.

    The present study aimed to investigate the molecular pathology of Waardenburg syndrome type II in three families, in order to provide genetic diagnosis and hereditary counseling for family members. Relevant clinical examinations were conducted on the probands of the three pedigrees. Peripheral blood samples of the probands and related family members were collected and genomic DNA was extracted. The coding sequences of paired box 3 (PAX3), microphthalmia‑associated transcription factor (MITF), sex‑determining region Y‑box 10 (SOX10) and snail family zinc finger 2 (SNAI2) were analyzed by polymerase chain reaction and DNA sequencing. The heterozygous mutation, c.649_651delAGA in exon 7 of the MITF gene was detected in the proband and all patients of pedigree 1; however, no pathological mutation of the relevant genes (MITF, SNAI2, SOX10 or PAX3) was detected in pedigrees 2 and 3. The heterozygous mutation c.649_651delAGA in exon 7 of the MITF gene is therefore considered the disease‑causing mutation in pedigree 1. However, there are novel disease‑causing genes in Waardenburg syndrome type II, which require further research.

    The PB1-F2 protein of the influenza A viruses (IAVs) can act as a virulence factor in mice. Its contribution to the virulence of IAV in swine, however, remains largely unexplored. In this study, we chose two genetically related H3N2 triple-reassortant IAVs to assess the impact of PB1-F2 in virus replication and virulence in pigs. Using reverse genetics, we disrupted the PB1-F2 ORF of A/swine/Wisconsin/14094/99 (H3N2) (Sw/99) and A/turkey/Ohio/313053/04 (H3N2) (Ty/04). Removing the PB1-F2 ORF led to increased expression of PB1-N40 in a strain-dependent manner. Ablation of the PB1-F2 ORF (or incorporation of the N66S mutation in the PB1-F2 ORF, Sw/99 N66S) affected the replication in porcine alveolar macrophages of only the Sw/99 KO (PB1-F2 knockout) and Sw/99 N66S variants. The Ty/04 KO strain showed decreased virus replication in swine respiratory explants, whereas no such effect was observed in Sw/99 KO, compared with the wild-type (WT) counterparts. In pigs, PB1-F2 did not affect virus shedding or viral load in the lungs for any of these strains. Upon necropsy, PB1-F2 had no effect on the lung pathology caused by Sw/99 variants. Interestingly, the Ty/04 KO-infected pigs showed significantly increased lung pathology at 3 days post-infection compared with pigs infected with the Ty/04 WT strain. In addition, the pulmonary levels of interleukin (IL)-6, IL-8 and gamma interferon were regulated differentially by the expression of PB1-F2. Taken together, these results indicate that PB1-F2 modulates virus replication, virulence and innate immune responses in pigs in a strain-dependent fashion.

    There is little data on the type of vegetable oil used and the prevalence of metabolic syndrome (MS) in Asian Indians. Food frequency questionnaire was used to document the type of cooking oil in 1875 adults in Chennai city. MS was assessed by new harmonizing criteria. The prevalence of MS was higher among sunflower oil users (30.7%) than palmolein (23.2%) and traditional oil (17.1%, p < 0.001) users. The higher prevalence of MS in sunflower oil group persisted even when stratified according to body mass index, except in obese groups. The risk of MS was further compounded by quantity of refined cereals consumed. Higher LA%E and linoleic acid/alpha-linolenic acid ratio in sunflower oil probably contributes to increased risk of MS.

    Asthma therapy with monoclonal antibodies is a promising and effective approach for those with a severe and refractory type of disease. Although such a targeted therapy is considered to be safe, unusual complications may occur. We present a case of a 45 year-old female patient with severe allergic asthma and chronic spontaneous urticaria, who developed autoimmune polyendocrine syndrome type 2 (APS-2) after 26 months of omalizumab administration. The patient was diagnosed with primary adrenal insufficiency (Addison's disease) and Hashimoto's thyroiditis accompanied by autoimmune atrophic gastritis. According to our knowledge this is the first description of APS-2 that developed in conjunction with omalizumab treatment, although we have no evidence that the observed phenomenon indicated a cause-effect relationship to omalizumab.

    Full Text Available Abstract Ehlers Danlos syndrome (EDS athrocalasia type (type VII, is characterized by joint hypermobility, skin hyperextensibility and tissue fragility. No heart involvement has been reported. Two forms have been described: type VII A and VII B. The abnormally processed collagen α2(I and the skipping of the exon 6 in COL1A2 gene are typically detected in EDS type VII B. We describe a seven-year old female, with a phenotype consistent with EDS type VII B and a diagnosis further confirmed by biochemical and molecular analyses. Cardiac ultrasound showed normal data in the first year of life. When she was 5 years old, the patient developed mitral valve regurgitation, and aortic and tricuspidal insufficiency at 7 years of age. To our knowledge, this is the first report of cardiac valvular involvement in EDS VII B. This feature probably has been underreported for the limited follow-up of the patients. Echocardiography might be warranted in the clinical assessment of EDS VII patients.

    Background Annoying snore is the principle symptom and problem in obstructive sleep apnea syndrome (OSAS). However, investigation has been hampered by the complex snoring sound analyses. Objective This study was aimed to investigate the energy types of the full-night snoring sounds in patients with OSAS. Patients and Method Twenty male OSAS patients underwent snoring sound recording throughout 6 hours of in-lab overnight polysomnogragphy. Snoring sounds were processed and analyzed by a new sound analytic program, named as Snore Map®. We transformed the 6-hour snoring sound power spectra into the energy spectrum and classified it as snore map type 1 (monosyllabic low-frequency snore), type 2 (duplex low-&mid-frequency snore), type 3 (duplex low- & high-frequency snore), and type 4 (triplex low-, mid-, & high-frequency snore). The interrator and test-retest reliabilities of snore map typing were assessed. The snore map types and their associations among demographic data, subjective snoring questionnaires, and polysomnographic parameters were explored. Results The interrator reliability of snore map typing were almost perfect (κ = 0.87) and the test-retest reliability was high (r = 0.71). The snore map type was proportional to the body mass index (r = 0.63, P = 0.003) and neck circumference (r = 0.52, P = 0.018). Snore map types were unrelated to subjective snoring questionnaire scores (All P>0.05). After adjustment for body mass index and neck circumference, snore map type 3–4 was significantly associated with severity of OSAS (r = 0.52, P = 0.026). Conclusions Snore map typing of a full-night energy spectrum is feasible and reliable. The presence of a higher snore map type is a warning sign of severe OSAS and indicated priority OSAS management. Future studies are warranted to evaluate whether snore map type can be used to discriminate OSAS from primary snoring and whether it is affected by OSAS management. PMID:23300931

    2009-11-01

    Full Text Available Abstract Background Loeys-Dietz syndrome (LDS is a rare autosomal dominant disorder showing the involvement of cutaneous, cardiovascular, craniofacial, and skeletal systems. In particular, LDS patients show arterial tortuosity with widespread vascular aneurysm and dissection, and have a high risk of aortic dissection or rupture at an early age and at aortic diameters that ordinarily are not predictive of these events. Recently, LDS has been subdivided in LDS type I (LDSI and type II (LDSII on the basis of the presence or the absence of cranio-facial involvement, respectively. Furthermore, LDSII patients display at least two of the major signs of vascular Ehlers-Danlos syndrome. LDS is caused by mutations in the transforming growth factor (TGF beta-receptor I (TGFBR1 and II (TGFBR2 genes. The aim of this study was the clinical and molecular characterization of two LDS patients. Methods The exons and intronic flanking regions of TGFBR1 and TGFBR2 genes were amplified and sequence analysis was performed. Results Patient 1 was a boy showing dysmorphic signs, blue sclerae, high-arched palate, bifid uvula; skeletal system involvement, joint hypermobility, velvety and translucent skin, aortic root dilatation, tortuosity and elongation of the carotid arteries. These signs are consistent with an LDSI phenotype. The sequencing analysis disclosed the novel TGFBR1 p.Asp351Gly de novo mutation falling in the kinase domain of the receptor. Patient 2 was an adult woman showing ascending aorta aneurysm, with vascular complications following surgery intervention. Velvety and translucent skin, venous varicosities and wrist dislocation were present. These signs are consistent with an LDSII phenotype. In this patient and in her daughter, TGFBR2 genotyping disclosed in the kinase domain of the protein the novel p.Ile510Ser missense mutation. Conclusion We report two novel mutations in the TGFBR1 and TGFBR2 genes in two patients affected with LDS and showing marked

    To define the predictors of long-term mortality in patients with type 2 diabetes mellitus and recent acute coronary syndrome. A total of 7226 patients from a randomized trial, testing the effect on cardiovascular outcomes of the dual peroxisome proliferator-activated receptor agonist aleglitazar in patients with type 2 diabetes mellitus and recent acute coronary syndrome (AleCardio trial), were analysed. Median follow-up was 2 years. The independent mortality predictors were defined using Cox regression analysis. The predictive information provided by each variable was calculated as percent of total chi-square of the model. All-cause mortality was 4.0%, with cardiovascular death contributing for 73% of mortality. The mortality prediction model included N-terminal proB-type natriuretic peptide (adjusted hazard ratio = 1.68; 95% confidence interval = 1.51-1.88; 27% of prediction), lack of coronary revascularization (hazard ratio = 2.28; 95% confidence interval = 1.77-2.93; 18% of prediction), age (hazard ratio = 1.04; 95% confidence interval = 1.02-1.05; 15% of prediction), heart rate (hazard ratio = 1.02; 95% confidence interval = 1.01-1.03; 10% of prediction), glycated haemoglobin (hazard ratio = 1.11; 95% confidence interval = 1.03-1.19; 8% of prediction), haemoglobin (hazard ratio = 1.01; 95% confidence interval = 1.00-1.02; 8% of prediction), prior coronary artery bypass (hazard ratio = 1.61; 95% confidence interval = 1.11-2.32; 7% of prediction) and prior myocardial infarction (hazard ratio = 1.40; 95% confidence interval = 1.05-1.87; 6% of prediction). In patients with type 2 diabetes mellitus and recent acute coronary syndrome, mortality prediction is largely dominated by markers of cardiac, rather than metabolic, dysfunction.

    Full Text Available Background: To determine whether uric acid levels are associated with the components of metabolic syndrome and whether uric acid is a significant factor for development of metabolic syndrome in the first-degree relatives of type 2 diabetic patients as high risk group. Materials and Methods: A total of 694 (182 male and 512 female, aged 30-69 years first-degree relatives of type 2 diabetic patients during 2007-2011 were enrolled. The height, weight, waist circumference, blood pressure, fasting plasma glucose, lipid profile and uric acid concentrations were measured. Metabolic syndrome was defined by NCEP-ATP III. Results: Uric acid was associated with waist circumference, blood pressure, triglyceride and HDL-cholesterol level in both sexes (r = 0.1-0.3, P < 0.05. The prevalence of metabolic syndrome in the fourth quartile of uric acid (64.4% of male and 60.2% of female population was significantly more than those in the first (25.5% of male and 31.2% of female population and second quartiles (33.3% of male and 32.0% of female population. The mean of uric acid in people with metabolic syndrome was significantly higher than in those without (6.6 ± 1.2 mg/ dL vs. 5.8 ± 1.2 mg/dL; P = 0.0001.The age-adjusted odds ratios (95% confidence interval of uric acid for metabolic syndrome in univariate analysis were [1.60 (1.23-2.07; P = 0.008] for men and [1.61 (1.34-1.92; P = 0.0001] for women but the effect of uric acid in multivariate logistic regression was not significant. Conclusions: Uric acid is associated with majority of the metabolic syndrome components. People with metabolic syndrome have higher uric acid levels. However, uric acid probably is not an independent factor to predict the metabolic syndrome.

    The association between human leukocyte antigens (HLA) and idiopathic nephrotic syndrome (INS) in children has been discussed in various studies. In this study, 59 Chinese children with steroid-sensitive nephritic syndrome (SSNS) in Taiwan were enrolled, and 33 patients underwent renal biopsy. The frequency of HLA-DR11 was found to be significantly higher and HLA-DR14 was lower in SSNS patients as compared with the healthy control group. In frequent relapsers, HLA-DR4 was more frequent, while HLA-DQB1*0602 was less frequent, as compared with infrequent relapsers. However, there was no significant difference between steroid-dependent and non-steroid-dependent patients. In patients who showed a response to levamisole, the HLA-DR9 and -DQB1*0303 alleles were more frequent, while HLA-DR13 was less frequent. In a comparison of HLA in different INS pathologies, HLA-DQB1*0401 was significantly frequent in IgM nephropathy. Even though we compared each group with the control group separately, the HLA distributions of both groups still differed from each other. Our data suggest that the immunogenic characteristics of children with SSNS in Taiwan are different from those of other populations. The common motif between different HLA alleles and the three-dimensional crystal structures may offer an explanation for the varying results from different populations. According to HLA typing, the results support the hypothesis that IgM nephropathy is a different entity from minimal change nephrotic syndrome. Copyright (c) 2009 S. Karger AG, Basel.

    We present the case of an 18-year-old woman with her second pregnancy, whose first pregnancy was complicated by polyhydramnios. At week 30, the dysmorph fetus died in utero and was delivered via cesarean section due to placental abruption, but the exact diagnosis was not recognized at that time. During the patient's second pregnancy, increasing polyhydramnios was detected from the 19th gestational week. Ultrasound signs of fetal malformation also appeared later: abnormal position of limbs, narrow chest, oedema around the skull, and absence of stomach content. At week 34, decompression amniocentesis became necessary. Chromosome analysis was also carried out and a normal karyotype was obtained. At 39th gestational week, amnioscopy proved meconium staining of the amniotic fluid, thus labour was induced. Following amniotomy, sustained fetal bradycardia commenced and an emergency caesarean section was performed. Despite complex resuscitation, the 3000 gram male newborn died 2.5 hours after delivery, due to respiratory failure. Autopsy and histopathologic examination revealed a large, oedematous head, micrognathia, macroglossia, laryngeal oedema, narrow chest with pulmonary hypoplasia, gracile limbs with muscle atrophy, gracile and bent fingers, and a short umbilical cord. Based on the medical history, the course of the disease and the phenotype of the newborn, Pena-Shokeir syndrome type I was diagnosed. In the second part of the article, we review the etiology, pathogenesis, prenatal diagnosis and differential diagnosis of this syndrome, as well as some aspects of genetic counseling in such cases. To our knowledge, this is the first reported case of Pena-Shokeir syndrome in Hungary.

    Waardenburg syndrome (WS) is an auditory-pigmentary disease characterized by a clinical and genetic variability. WS is classified into four types depending on the presence or absence of additional symptoms: WS1, WS2, WS3 and WS4. Type 1 and 3 are mostly caused by PAX3 mutations, while type 2 and type 4 are genetically heterogeneous. The aims of this study are to confirm the diagnostic of WS1 by the sequencing of PAX3 gene and to evaluate the genotype phenotype correlation. A clinical classification was established for 14 patients WS, as proposed by the Waardenburg Consortium, and noted a predominance of type 1 and type 2 with 6 patients WS1, 7 patients WS2 and 1 patient WS3. A significant inter and intra-familial clinical heterogeneity was also observed. A sequencing of PAX3 gene in the 6 patients WS1 confirmed the diagnosis in 4 of them by revealing three novel mutations that modify two functional domains of the protein: the c.942delC; the c.933_936dupTTAC and the c.164delTCCGCCACA. These three variations are most likely responsible for the phenotype, however their pathogenic effects need to be confirmed by functional studies. The MLPA analysis of the 2 patients who were sequence negative for PAX3 gene revealed, in one of them, a heterozygous deletion of exons 5 to 9 confirming the WS1 diagnosis. Both clinical and molecular approaches led to the conclusion that there is a lack of genotype-phenotype correlation in WS1, an element that must be taken into account in genetic counseling. The absence of PAX3 mutation in one patient WS1 highlights the fact that the clinical classification is sometimes insufficient to distinguish WS1 from other types WS hence the interest of sequencing the other WS genes in this patient.

    The emergence of type 1 porcine reproductive and respiratory syndrome virus (PRRSV) has been noticed recently in China. In the present study, the complete genomic characterization of a strain of type 1 PRRSV (designated GZ11-G1) was described and its pathogenicity for piglets was analyzed. The results showed that the complete genome of GZ11-G1 with a size of 15,094 nt, excluding the poly (A) tails, shared 80.2-96.3% identity with the representative strains of type 1 PRRSV, and in particular, it had highest homology (96.3%) with Amervac PRRS, a live vaccine virus of type 1 PRRSV and SHE, a rescued virus from an infectious clone of Amervac PRRS virus. Compared with the vaccine virus, the nonstructural and structural proteins of GZ11-G1 displayed extensive amino acid variations except for its ORF5a. GZ11-G1 was clustered with the strains of type 1 PRRSV including Cresa3267, Cresa3249, Cresa3256, Olot/91, 9625/2012, ESP-1991-Olot91 and Amervac PRRS vaccine virus by further phylogenetic analysis. Moreover, GZ11-G1 was shown to cause fever, higher viremia and lung and lymph node lesions in piglets. Our findings indicate that GZ11-G1 is genetically related to type 1 PRRSV strains within the cluster formed by Cresa3267, Cresa3249, Cresa3256, Olot/91, 9625/2012, ESP-1991-Olot91 and Amervac PRRS vaccine virus, and it is a pathogenic for piglets. This study aids in understanding the genetic variation and evolution of type 1 PRRSV. Copyright © 2016 Elsevier B.V. All rights reserved.

    The Ehlers-Danlos syndrome (EDS), dermatosparaxis type, is a recessively inherited connective tissue disorder caused by deficient activity of ADAMTS-2, an enzyme that cleaves the aminoterminal propeptide domain of types I, II, and III procollagen. Only 10 EDS dermatosparaxis patients have been reported, all presenting a recognizable phenotype with characteristic facial gestalt, extreme skin fragility and laxity, excessive bruising, and sometimes major complications due to visceral and vascular fragility. We report on five new EDS dermatosparaxis patients and provide a comprehensive overview of the current knowledge of the natural history of this condition. We identified three novel homozygous loss-of-function mutations (c.2927_2928delCT, p.(Pro976Argfs*42); c.669_670dupG, p.(Pro224Argfs*24); and c.2751-2A>T) and one compound heterozygous mutation (c.2T>C, p.? and c.884_887delTGAA, p.(Met295Thrfs26*)) in ADAMTS2 in five patients from four unrelated families. Three of these displayed a phenotype that was strikingly milder than that of previously reported patients. This study expands the clinical and molecular spectrum of the dermatosparaxis type of EDS to include a milder phenotypic variant and stresses the importance of good clinical criteria. To address this, we propose an updated set of criteria that accurately captures the multisystemic nature of the dermatosparaxis type of EDS.Genet Med 18 9, 882-891.

    Finite time processes within the limits of the Newton equation and zero inertia motion (i.e., road to chaos) are studied by numerically solving the ordinary, stochastic Langevin equation in 1D for a free particle with inertial moving in a medium with viscosity γ. In this simulations, the scaling behaviour of particle trajectories χ(t) and velocities v(t) with time are derived and the inclusion of non-zero particle masses is shown to define the asymptotic time limit τ c at which - independently of γ - the system evolves into the well-known statistically stationary state characterized by 2 (t) > is proportional to t and flicker noise. The time τ c is further analysed from the correlation length given by the 2-point autocorrelation function of the particle velocity at each value of γ. It is found that the noise power spectrum of v(t) is characterized by flicker noise for frequencies f ≤ f c ∼ 1/τ c , whereas for f > f c , the noise power spectra behave as 1/f υ , where υ varies between the limits of Newton's equation (i.e., υ = 3) and road to chaos (i.e., υ = 1). Furthermore, at times τ c and 0 f (γ) while the single particle trajectories are shown to display a rather different subset of exponents on increasing γ. Generic features of this transition are nicely given by Poincare maps in the velocity space. (author). 23 refs, 8 figs

    The locus for Usher syndrome type I (USH1C) in the Acadian population is in the p15.1-p14 region of chromosome 11. This recessive disease is characterized by sensorineural hearing impairment, vestibular dysfunction, and pigmentary retinopathy. Three separate loci have been localized for Usher syndrome type I. All Acadian, but no non-Acadian, families show linkage to the 11p locus, suggesting a founder effect in the Acadian population. Linkage and haplotype analyses of eight markers spanning 10 centiMorgans demonstrate that USH1C lies between D11S1397 and D11S1310. Based on analyses of Usher and CEPH families the most likely linkage map for the eight markers is: D11S569-(.02)-D11S861-(.01)-D11S419-(.01)-D11S1397-(.004)-D11S921-(.007)-D11S1310-(.01)-D11S899-(.04)-D11S928. Evidence of linkage disequilibrium with USH1C was found for all markers, indicating a recent origin of a unique mutation. Parental haplotypes were separated into those with the disease allele and those with the normal allele at the USH1C locus. Of the 54 chromosomes with the disease allele, 17 had an identical haplotype for the eight markers. All but one of the haplotypes on the remaining 37 chromosomes could be explained by a few recombination events, suggesting that a single mutation is responsible for nearly all cases of Usher syndrome type I in the Acadian population. The same alleles were found at D11S921 and D11S1310 on 50 of the 54 chromosomes with the disease allele and on only 5 of the 50 chromosomes with the normal allele. Analysis of recombination and linkage disequilibrium between USH1C and each of the markers suggests that the age of the mutation is approximately 15 generations, which corresponds with the time that the Acadians arrived in the Canadian territory of Acadia. The analysis indicates that this mutation was already established in the Acadians who made their way to Louisiana after 1755.

    Joint hypermobility syndrome/Ehlers-Danlos syndrome hypermobility type (JHS/EDS-HT) is an evolving and protean disorder mostly recognized by generalized joint hypermobility and without a defined molecular basis. JHS/EDS-HT also presents with other connective tissue features affecting a variety of structures and organs, such as skin, eye, bone, and internal organs. However, most of these signs are present in variable combinations and severity in many other heritable connective tissue disorders. Accordingly, JHS/EDS-HT is an "exclusion" diagnosis which needs the absence of any consistent feature indicative of other partially overlapping connective tissue disorders. While both Villefranche and Brighton criteria include such an exclusion as a mandatory item, a systematic approach for reaching a stringent clinical diagnosis of JHS/EDS-HT is still lacking. The absence of a consensus on the diagnostic approach to JHS/EDS-HT concerning its clinical boundaries with similar conditions contribute to limit our actual understanding of the pathologic and molecular bases of this disorder. In this review, we revise the differential diagnosis of JHS/EDS-HT with those heritable connective tissue disorders which show a significant overlap with the former and mostly include EDS classic, vascular and kyphoscoliotic types, osteogenesis imperfecta, Marfan syndrome, Loeys-Dietz syndrome, arterial tortuosity syndrome, and lateral meningocele syndrome. A diagnostic flow chart is also offered with the attempt to support the less experienced clinician in stringently recognizing JHS/EDS-HT and stimulate the debate in the scientific community for both management and research purposes. © 2015 Wiley Periodicals, Inc.

    Usher syndrome is a genetic condition causing deaf-blindness and is one of the most common causes of syndromic deafness. Individuals with USH1 in Sweden born during the last 15 years have typically received cochlear implants (CI) as treatment for their congenital, profound hearing loss. Recent research in genetics indicates that the cause of deafness in individuals with Usher type 1 (USH1) could be beneficial for the outcome with cochlear implants (CI). This population has not previously been the focus of cognitive research. The present study aims to examine the phonological and lexical skills and working memory capacity (WMC) in children with USH1 and CI and to compare their performance with children with NH, children with hearing-impairment using hearing-aids and to children with non-USH1 deafness using CI. The participants were 7 children aged 7-16 years with USH1 and CI. The participants performed 10 sets of tasks measuring phonological and lexical skills and working memory capacity. The results indicate that children with USH1 and CI as a group in general have a similar level of performance on the cognitive tasks as children with hearing impairment and hearing aids. The group with USH1 and CI has a different performance profile on the tests of working memory, phonological skill and lexical skill than children with non-USH1 deafness using CI, on tasks of phonological working memory and phonological skill.

    We report a case of retinal and posterior ocular findings in a 33-year-old man diagnosed with Hunter syndrome (Mucopolysaccharidosis type II) in a multimodal imaging way. Our patient was complaining of blurred night vision for the past 3 years. He had not received any systemic treatment for Hunter syndrome. Vision acuity was 20/20 in both eyes and corneas were clear. Fundus examination revealed bilateral crowded and hyperemic optic nerve heads (elevated in the ocular ultrasound) and areas of subretinal hypopigmentation. There was hyperautofluorescence at the central fovea and perifovea, and a diffuse bilateral choroidal fluorescence in angiography. Macular SD-OCT showed a thinning of the external retina at the perifovea in both eyes. Visual field testing showed a bilateral ring scotoma. The full field ERG was subnormal, with a negative response in the scotopic phase. Visual Evoked Potencial test and cranial MRI were normal. Our multimodal analysis reported here attempted to contribute to the knowledge of the natural history of GAG deposition in the eye, focusing on the retina and retinal pigment epithelium. Defining this natural history is essential for a proper comparison with Hunter patients receiving systemic treatment, thus determining if it can or cannot improve retinal function in humans with this disorder.

    To determine the genetic cause for a patient featuring decreased pigmentation of the skin and iris, hearing loss and multiple congenital anomalies. Routine chromosomal banding was performed to analyze the karyotype of the patient and his parents. Single nucleotide polymorphism array (SNP array) was employed to identify cryptic chromosome aberrations, and quantitative real-time PCR was used to confirm the results. Karyotype analysis has revealed no obvious anomaly for the patient and his parents. SNP array analysis of the patient has demonstrated a 3.9 Mb deletion encompassing 3p13p14.1, which caused loss of entire MITF gene. The deletion was confirmed by quantitative real-time PCR. Clinical features of the patient have included severe bilateral hearing loss, decreased pigmentation of the skin and iris and multiple congenital anomalies. The patient, carrying a 3p13p14.1 deletion, has features of Tietz syndrome/Waardenburg syndrome type IIa. This case may provide additional data for the study of genotype-phenotype correlation of this disease.

    Background The aim of this study was to describe the pattern of inheritance and the clinical features in a large family with Waardenburg syndrome type I (WS1), detailing the dental abnormalities and screening for PAX3 mutations. Material and Methods To characterize the pattern of inheritance and clinical features, 29 family members were evaluated by dermatologic, ophthalmologic, otorhinolaryngologic and orofacial examination. Molecular analysis of the PAX3 gene was performed. Results The pedigree of the family,including the last four generations, was constructed and revealed non-consanguineous marriages. Out of 29 descendants, 16 family members showed features of WS1, with 9 members showing two major criteria indicative of WS1. Five patients showed white forelock and iris hypopigmentation, and four showed dystopia canthorum and iris hypopigmentation. Two patients had hearing loss. Dental abnormalities were identified in three family members, including dental agenesis, conical teeth and taurodontism. Sequencing analysis failed to identify mutations in the PAX3 gene. Conclusions These results confirm that WS1 was transmitted in this family in an autosomal dominant pattern with variable expressivity and high penetrance. The presence of dental manifestations, especially tooth agenesis and conical teeth which resulted in considerable aesthetic impact on affected individuals was a major clinical feature. Clinical relevance: This article reveals the presence of well-defined dental changes associated with WS1 and tries to establish a possible association between these two entities showing a new spectrum of WS1.

    The novel compound heterozygous mutation in PAX3 was the key genetic reason for WS1 in this family, which was useful to the molecular diagnosis of WS1. Screening the pathogenic mutations in a four generation Chinese family with Waardenburg syndrome type I (WS1). WS1 was diagnosed in a 4-year-old boy according to the Waardenburg syndrome Consortium criteria. The detailed family history revealed four affected members in the family. Routine clinical, audiological examination, and ophthalmologic evaluation were performed on four affected and 10 healthy members in this family. The genetic analysis was conducted, including the targeted next-generation sequencing of 127 known deafness genes combined with Sanger sequencing, TA clone and bioinformatic analysis. A novel compound heterozygous mutation c.[169_170insC;172_174delAAG] (p.His57ProfsX55) was identified in PAX3, which was co-segregated with WS1 in the Chinese family. This mutation was absent in the unaffected family members and 200 ethnicity-matched controls. The phylogenetic analysis and three-dimensional (3D) modeling of Pax3 protein further confirmed that the novel compound heterozygous mutation was pathogenic.

    Full Text Available The autoimmune polyendocrinopathy syndrome type 1 (APS-1, also known as candidiasis ectodermal-autoimmune polyendocrinopathy-dystrophy (APECED, it is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene (AIRE. Therefore, it is immunologically characterized by cell attack and / or antibodymediated generating the destruction of target organs. Furthermore, it is characterized by the pathognomonic triad chronic candidiasis, hypoparathyroidism and Addison's disease with many other endocrine and non-endocrine events. Soon, the diagnosis is made based on the presence of two of the three classic features and treatment aims to control the numerous deficiencies that patients may present. This literature review was aimed at understanding the involvement of AIRE gene in relation to immunological aspects present and, consequently, clinical manifestations of this disease. Thus, evidence of the need to broaden the discussion about this disease, in order to improve the quality of life of patients by early diagnosis and treatment and are in accordance with the clinical manifestations of each patient. Thereby, qualitative research involved scientific articles from electronic journals LILACS (Latin American and Caribbean, SCIELO (Scientific Electronic Library Online and NCBI (National Center for Biotechnology Information, between the years 2009 and 2016. Pursuant to, there is the relevance of this review, it is noted that, although the authors converge on views on this syndrome, there are still many unclear matters with regard to the mechanisms of the disease. This highlights the need to promote more discussion on this topic.

    Autoimmune Polyglandular Syndrome type 1 (APS-1) is a subtype of the autoimmune polyendocrine syndrome characterized by the simultaneous or sequential dysfunction of multiple endocrine or non-endocrine glands. A clinical diagnosis of APS-1 is typically based on the presence of at least two of three following criteria: chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. The first identified causative mutated gene for APS-1 is autoimmune regulator (AIRE) encoding a critical transcription factor, which is primarily expressed in the medullary thymic epithelial cells (mTECs) for generating central immune tolerance. A wide range of chronic, debilitating complications, with no obvious correlation with genetics, makes a diagnosis of APS-1 challenging early in the disease course. Managing APS-1 is difficult due to its complexity, especially the intricate relationships within manifestations and genetic mutations. The past decades have witnessed dramatic progress in elucidating the function of AIRE and conducting large-scale cohort studies in APS-1. However, no clear evidence-based guidelines have been established in APS-1. In this review, we provide a detailed critical overview of the study history, epidemiology, clinical features, and related mechanisms of autoimmunity in APS-1, as well as currently available therapies for this autoimmune disorder.

    Diabetes and Nephrotic syndrome (NS) promote plaque-related gingivitis and yeast-like fungal infections. The study assesses the impact of Candida spp. and general disease- or treatment-related factors on plaque-related gingivitis severity in children and adolescents with Nephrotic syndrome /diabetes. Body mass index (BMI), BMI standard deviation score, and oral cavity (Plaque Index--PLI, Gingival Index--GI, mucosa status, presence and Candida enzymatic activity) were assessed in 96 patients (32 with NS: 30- immunosuppressive treatment, 35--type 1 diabetes, and 29 generally healthy), aged; 3-18 years. Laboratory included cholesterol and triglyceride measurements; in diabetic subjects- glycated haemoglobin, in NS: total protein, albumin, creatinine, haemoglobin, haematocrit, white cell count, urinary protein excretion. Medical records supplied information on disease duration and treatment. A statistical analysis was performed; Kendall Tau coefficient, chi-square test, t-test, and multiple regression analysis ( P Gingivitis occurred more frequently in patients with NS/diabetes. Gingivitis severity was correlated with PLI, age, and yeast enzyme activity in NS--to with immunosuppressive treatment with >1 drug, drug doses, treatment duration, lipid disorders, and BMI; in diabetes, with blood glucose and glycated haemoglobin >8%. Poor hygiene control is the main cause of gingivitis. Gingivitis severity is most likely related to age, lipid disorders and increase in body mass. Candida spp., in uncompensated diabetes and in those using immunosuppressive treatment, might intensify plaque-related gingivitis.

    Dietary fiber may contribute to both the prevention and treatment of type 2 diabetes mellitus (T2DM). In epidemiological studies the intake of insoluble fiber, but not the intake of soluble fiber, has been inversely associated with the incidence of T2DM. In contrast, in postprandial studies, meals containing sufficiently quantities of beta-glucan, psyllium, or guar gum have decreased insulin and glucose responses in both healthy individuals and patients with T2DM. Diets enriched sufficiently in soluble fiber may also improve overall glycemic control in T2DM. Insoluble fiber has little effect on postprandial insulin and glucose responses. Fiber increases satiety. In some studies, insoluble fiber has been associated with less weight gain over time. Limited cross-sectional evidence suggests an inverse relationship between intake of cereal fiber and whole-grains and the prevalence of the metabolic syndrome. Although long-term data from trials focusing on specifically dietary fiber are lacking, meeting current recommendations for a minimum fiber intake of 25 g/d based on a diet rich in whole grains, fruits and legumes will probably decrease the risk of obesity, the metabolic syndrome and T2DM.

    Polyglandular autoimmune syndromes are rare diseases based on autoimmune mechanisms in which endocrine and non-endocrine disorders coexist. In type 1 the characteristic manifestations are chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. A case is presented of a patient with typical clinical sequence, along with other changes, and in whom a mutation in homozygosis, C322fsX372, was detected after performing a molecular analysis of autoimmunity regulator gene (AIRE). Inheritance is autosomal recessive, associated with mutations in the AIRE gene, which encodes a protein involved in autoimmunity and immunodeficiency. For diagnosis, At least two of the three major clinical manifestations are required for a diagnosis. However, only one of them is necessary in the study of relatives of affected patients. These syndromes must be diagnosed early, given their high morbidity and mortality. Every manifestation needs to be treated, in order to maintain the quality of life.

    Children with Down syndrome (DS), who are likely to suffer from a large number of musculoskeletal problems, tend to have a unique pattern of walking in clinical settings. Despite such apparent uniqueness, few studies have empirically investigated gait development pattern in DS children, especially at an earlier age. We therefore conducted gait analysis in young DS children who are prescribed insoles, to explore how their gait patterns develop, using the gait parameters identified by Sutherland et al. as determinants of gait maturity of typical children. Participants consisted of 63 DS children (31 boys) aged 1-6 years (mean, 4 years 1 month) with a diagnosis of flat feet who were prescribed orthotic insoles. A 2.4 m sheet-type gait analyzer was used to analyze gait pattern. We measured the following variables: walking velocity (cm/min), cadence (steps/min), step length (cm), and single-limb stance phase ratio (%), and examined their relationship with age on regression analysis. Walking velocity and step length were significantly and positively related to age. Cadence was also significantly, but negatively associated with age. In contrast, SLS phase ratio did not have a statistically significant relationship with age. Down syndrome children have unique gait development patterns. Although walking velocity, cadence, and step length were found to develop with age, as in typical children, SLS phase ratio did not change with age in DS children. Further studies with a larger sample are necessary to replicate these findings. © 2015 Japan Pediatric Society.

    To explore the correlation between Chinese medical (CM) syndrome types of chronic atrophic gastritis (CAG) patients and Helicobacter pylori (Hp) infection, polymorphisms of IL-1B, and IL-1β. Totally 192 CAG patients and 202 healthy subjects (as the healthy control group) were recruited in this case-control study. The Hp infection was tested by 13C-urea breath test and colloidal gold-labeled assay (GICA). The concentration of peripheral blood IL-1β was measured by ELISA. The polymorphisms of IL-1B gene in the promoter region were analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Pi-Wei weakness syndrome (PWWS) was dominant in CAG patients (31.77%, 61/192 cases). The Hp infection ratio in CAG patients was 53.65% (103/192 cases), of which, Pi-Wei damp-heat syndrome(PWDHS, 64.86%, 24/37 cases) and Gan-Wei disharmony syndrome (GWDS, 66.67%, 24/36 cases) were dominant. Compared with the health control group, the plasma concentration of IL-1β was obviously elevated in CAG patients with PWDHS, GWDS, and static blood obstructing collaterals syndrome (SBOCS) (all P 0.05). The incidence risk of CAG was not associated with IL-1B polymorphism. But CM syndrome types of CAG patients was associated with Hp infection and peripheral blood IL-1β levels.

    Full Text Available The action of glucocorticoids is modulated by isoenzymes 11?-hidroxiesteróide desidrogenases (11?-HSD type 1 and 2. The knowledge concerning these isoenzymes contribute to the understanding of the regulatory mechanisms involved in several disease processes of the Cushing’s syndrome, such as obesity, osteoporosis and hypertension. With the aim at describing the action of isoenzymes 11?-HSD type 1 and 2 in the Cushing’s syndrome, a literature review was done from 1990 - 2006 using the Medline data base, searching for the following key-words: Cushing’s syndrome, glucocorticoids, 11?-hydroxysteroid dehydrogenase, hypertension, osteoporosis and obesity. Review studies, meta-analysis and original articles were selected and chosen on the basis of methodological aspects and relevance. The exact mechanism by which cortisol increases blood pressure is not completely understood, but it involves, among others factors, changes in the sodium homeostasis. The conversion of cortisone to cortisol through expression of 11?-HSD1 induces the differentiation of preadipoctyes to mature adipoctyes and such patients develop an increase in visceral fat. The prevalence of osteoporosis in adult patients with Cushing’s syndrome is approximately 50% and glucocorticoids play a strong effect on the bone and calcium metabolism. The isoenzymes 11?-HSD1 and 11?-HSD2 have an important function in these several pathophysiology processes; however the isoenzymes action in the pathophysiology of the Cushing’s syndrome need to be more investigated.

    Full Text Available Background Subjects with metabolic syndrome (MetS have a greater risk for acquiring type 2 diabetes mellitus (type 2 DM. The MetS criteria usually used are those of the National Cholesterol Education Program Expert Panel (NCEP and Adult Treatment Panel III (ATP III and of the International Diabetes Federation (IDF. This study aimed to evaluate the modified NCEP-ATP III and IDF criteria as predictor of type 2 DM among subjects with MetS.   Methods A cohort study was conducted among 4240 subjects with MetS. MetS was determined according to the modified NCEP-ATP III and IDF criteria. The study followed up 3324 non-diabetic subjects of the cohort study of non-communicable disease (NCD risk factors (NCD study during a 2-year period. Type 2 DM was determined from the diagnosis by health personnel or from fasting blood glucose of ≥126 mg/dL or blood glucose of ≥200 mg/dL, 2 hours after 75g glucose loading.   Results The MetS prevalence based on modified NCEP ATP III and IDF criteria in non-DM subjects was 17.1% and 15.6%, respectively. The risk for DM in subjects with MetS using modified NCEP ATP III and IDF criteria was 4.7 (CI 95%: 3.4-6.5 and 4.1 (CI 95%: 3.0-5.7, respectively.   Conclusions Both MetS criteria can be used as predictors of the occurrence of DM type 2, but the modified NCEP-ATP III is more properly applied than the IDF criteria in subjects with MetS. Screening programs and routine monitoring of MetS components are required for early detection of type 2 DM.

    2017-12-01

    Polycystic ovary syndrome (PCOS) is recognized as one of the most common endocrinopathies in women of reproductive age, associated with metabolic sequelae which includes increased risk factors for impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and cardiovascular disease (CVD). The adverse effects of DM2 affects a woman throughout her lifespan. Health care expenditure of DM2 highlights the need for prevention through appropriate screening, diagnosis and intervention. Lifestyle modification (LSM) programs that include diet and/or physical activity are suggested for patients characterized as prediabetic to delay the onset of adult DM2. Diet (i.e. low carbohydrate), combination of aerobic and resistance exercise with high intensity interval training (HIT) 150 to 175min/week with resistance exercise 2 to 3days/week and weight loss may be valuable supporters in the fight against IR, IGT and DM2 associated with PCOS.

    To explore the molecular etiology of two pedigrees affected with type II Waardenburg syndrome (WS2) and to provide genetic diagnosis and counseling. Blood samples were collected from the proband and his family members. Following extraction of genomic DNA, the coding sequences of PAX3, MITF, SOX10 and SNAI2 genes were amplified with PCR and subjected to DNA sequencing to detect potential mutations. A heterozygous deletional mutation c.649_651delAGA in exon 7 of the MITF gene has been identified in all patients from the first family, while no mutation was found in the other WS2 related genes including PAX3, MITF, SOX10 and SNAI2. The heterozygous deletion mutation c.649_651delAGA in exon 7 of the MITF gene probably underlies the disease in the first family. It is expected that other genes may also underlie WS2.

    Full Text Available Hermansky–Pudlak syndrome type 2 (HPS2 is a rare autosomal recessive disorder resulting from functional mutations in the adaptor-related protein complex 3, beta 1 subunit (AP3B1 gene. This gene plays a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. Here we describe the generation of an HPS2 iPS cell line (CHOPHPS2 using a Cre-excisable polycistronic STEMCCA lentivirus. This line was derived from human fibroblasts isolated from a patient carrying two mutations in the AP3B1 gene. The patient presented with severe neutropenia, ocular albinism, interstitial pulmonary fibrosis, hemorrhagic diathesis, and an absence of platelet-dense granules.

    Autoimmune polyglandular syndrome type 1 (APS-1), also referred to as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), is a rare autoimmune disease that results from autosomal recessive mutations of the human autoimmune regulatory (AIRE) gene. We present the case of a 17-year-old North American girl of primarily Norwegian descent with a novel AIRE gene mutation causing APS-1. In addition to the classic triad of chronic candidiasis, hypoparathyoidism and autoimmune adrenocortical insufficiency, she also has vitiligo, intestinal malabsorption, autoimmune hepatitis, autoimmune hypothyroidism, myositis, myalgias, chronic fatigue, and failure to thrive. Genetic testing revealed heterozygosity for c.20_115de196 and c.967_979del13 mutations in the AIRE gene. The AIRE gene c.20_115de196 mutation has not been previously reported. PMID:24945421

    Full Text Available Down syndrome (DS, trisomy 21, is the most common viable chromosomal disorder, with an incidence of 1 in 800 live births. Its phenotypic characteristics include intellectual impairment and several other developmental abnormalities, for the majority of which the pathogenetic mechanisms remain unknown. Several models have been used to investigate the mechanisms by which the extra copy of chromosome 21 leads to the DS phenotype. In the last five years, several laboratories have been successful in reprogramming patient cells carrying the trisomy 21 anomaly into induced pluripotent stem cells, i.e., T21-iPSCs. In this review, we summarize the different T21-iPSCs that have been generated with a particular interest in the technical procedures and the somatic cell types used for the reprogramming.

    Glucocorticoids are primary therapy of idiopathic nephrotic syndrome (INS). However, not all children respond to steroid therapy. We assessed glomerular glucocorticoid receptor expression in fifty-one children with INS and its relation to response to steroid therapy and to histopathological type. Clinical, laboratory and glomerular expression of glucocorticoid receptors were compared between groups with different steroid response. Glomerular glucocorticoid expression was slightly higher in controls than in minimal change early responders, which in turn was significantly higher than in minimal change late responders. There was significantly lower glomerular glucocorticoid receptor expression in steroid-resistance compared to early responders, late responders and controls. Glomerular glucocorticoid expression was significantly higher in all minimal change disease (MCD) compared to focal segmental glomerulosclerosis. In INS, response to glucocorticoid is dependent on glomerular expression of receptors and peripheral expression. Evaluation of glomerular glucocorticoid receptor expression at time of diagnosis of NS can predict response to steroid therapy.

    Many clinical features are common for patients with type 2 diabetes mellitus (T2DM) and Cushing's syndrome (CS) such as central obesity, hypertension and dyslipidaemia. Patients with CS often have T2DM. Because T2DM is much more frequent than CS, it is possible that some patients with T2DM have...... increased production of cortisol and thus represent patients with CS. The aim of this review was to evaluate the prevalence of CS in patients with T2DM. A search was performed in PubMed and Medline. We found seven prospective studies, two case-control studies and two cross-sectional studies...... with T2DM varies widely between the different studies, ranging from 0-9.4%. This may be due to patient selection, differences in test methodology (including choice of test), cutoff values and different cortisol assays. The true prevalence of CS in T2DM has not been determined. We need more studies...

    Porcine reproductive and respiratory syndrome virus (PRRSV) has spread throughout Asia, causing significant losses to commercial farmers and smallholders. However, little is known about PRRS in Nepal, a South Asian country with a gradually increasing pig industry. In 2011, a pilot project was initiated to identify the status of PRRSV in pigs of the Kathmandu Valley of Nepal. Out of 98 serum samples, 31 (32 %; 95 % CI 23-42 %) were found positive by ELISA. All positive samples belonged to the type 2 (North American) genotype. Molecular evaluation by real-time PCR however did not yield positive results. At the herd level, seropositivity was associated with a history of abortion and premature birth. Veterinarians, farmers and government should be aware of this threat to the Nepalese pig industry and initiate an appropriate response.

    Full Text Available Bartter syndrome (BS I–IV is a rare autosomal recessive disorder affecting salt reabsorption in the thick ascending limb of the loop of Henle. This report highlights clinicopathological findings and genetic studies of classic BS in a 22-year-old female patient who presented with persistent mild proteinuria for 2 years. A renal biopsy demonstrated a mild to moderate increase in the mesangial cells and matrix of most glomeruli, along with marked juxtaglomerular cell hyperplasia. These findings suggested BS associated with mild IgA nephropathy. Focal tubular atrophy, interstitial fibrosis, and lymphocytic infiltration were also observed. A genetic study of the patient and her parents revealed a mutation of the CLCNKB genes. The patient was diagnosed with BS, type III. This case represents an atypical presentation of classic BS in an adult patient. Pathologic findings of renal biopsy combined with genetic analysis and clinicolaboratory findings are important in making an accurate diagnosis.

    Long QT syndrome type 1 (LQT1) is the most common type of all Long QT syndromes (LQTS) and occurs due to mutations in KCNQ1. Biallelic mutations with deafness is called Jervell and Lange-Nielsen syndrome (JLNS) and without deafness is autosomal recessive Romano-Ward syndrome (AR RWS). In this prospective study, we report biallelic mutations in KCNQ1 in Indian patients with LQT1 syndrome. Forty patients with a clinical diagnosis of LQT1 syndrome were referred for molecular testing. Of these, 18 were excluded from the analysis as they did not fulfill the inclusion criteria of broad T wave ECG pattern of the study. Direct sequencing of KCNQ1 was performed in 22 unrelated probands, parents and at-risk family members. Mutations were identified in 17 patients, of which seven had heterozygous mutations and were excluded in this analysis. Biallelic mutations were identified in 10 patients. Five of 10 patients did not have deafness and were categorized as AR RWS, the rest being JLNS. Eight mutations identified in this study have not been reported in the literature and predicted to be pathogenic by in silico analysis. We hypothesize that the homozygous biallelic mutations identified in 67% of families was due to endogamous marriages in the absence of consanguinity. This study presents biallelic gene mutations in KCNQ1 in Asian Indian patients with AR JLNS and RWS. It adds to the scant worldwide literature of mutation studies in AR RWS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    To examine and expand the genetic spectrum of Waardenburg syndrome type 1 (WS1). Clinical features related to Waardenburg syndrome (WS) were examined in a five-year old patient. Mutation analysis of genes related to WS was performed in the proband and her parents. Molecular modeling of EDNRB and the p.R319W mutant was conducted to predict the pathogenicity of the mutation. The proband showed sensorineural hearing loss, heterochromia iridis, and dystopia canthorum, fulfilling the clinical criteria of WS1. Genetic analyses revealed that the proband had no mutation in PAX3 which has been known as the cause of WS1, but had a homozygous missense mutation (p.R319W) in endothelin receptor type B (EDNRB) gene. The asymptomatic parents had the mutation in a heterozygote state. This mutation has been previously reported in a heterozygous state in a patient with Hirschsprung's disease unaccompanied by WS, but the patient and her parents did not show any symptoms in gastrointestinal tract. Molecular modeling of EDNRB with the p.R319W mutation demonstrated reduction of the positively charged surface area in this region, which might reduce binding ability of EDNRB to G protein and lead to abnormal signal transduction underlying the WS phenotype. Our findings suggested that autosomal recessive mutation in EDNRB may underlie a part of WS1 with the current diagnostic criteria, and supported that Hirschsprung's disease is a multifactorial genetic disease which requires additional factors. Further molecular analysis is necessary to elucidate the gene interaction and to reappraise the current WS classification. Copyright © 2017 Elsevier B.V. All rights reserved.

    Tietz syndrome and Waardenburg syndrome type 2A are allelic conditions caused by MITF mutations. Tietz syndrome is inherited in an autosomal dominant pattern and is characterized by congenital deafness and generalized skin, hair, and eye hypopigmentation, while Waardenburg syndrome type 2A typically includes variable degrees of sensorineural hearing loss and patches of de-pigmented skin, hair, and irides. In this paper, we report two unrelated families with MITF mutations. The first family showed an autosomal dominant pattern and variable expressivity. The second patient was isolated. MITF gene analysis in the first family demonstrated a c.648A>C heterozygous mutation in exon 8 c.648A>C; p. (R216S), while in the isolated patient, an apparently de novo heterozygous c.1183_1184insG truncating mutation was demonstrated in exon 10. All patients except one had bilateral reduced ocular anteroposterior axial length and a high hyperopic refractive error corresponding to posterior microphthalmos, features that have not been described as part of the disease. Our results suggest that posterior microphthalmos might be part of the clinical characteristics of Tietz/Waardenburg syndrome type 2A and expand both the clinical and molecular spectrum of the disease. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    2016-07-12

    Type 1 autoimmune polyglandular syndrome (APS1) is a rare autosomal recessive disease, caused by mutations in the autoimmune regulator gene (AIRE); the encoded Aire protein plays an important role in the establishment of the immunological tolerance acting as a transcriptional regulator of the expression of organ-specific antigens within the thymus in perinatal age. While a high prevalence for this rare syndrome is reported in Finland and Scandinavia (Norway), autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) cohorts of patients are also detected in continental Italy and Sardinia, among Iranian Jews, as well as in other countries. The syndrome is diagnosed when patients present at least two out of the three fundamental disorders including chronic mucocutaneous candidiasis, hypoparathyroidism, and Addison's disease. Among the associated conditions insulin-dependent diabetes mellitus (Type 1 diabetes) has been rarely reported in different series of patients and occurring more frequently in Finnish APECED patients. In this review, we analyze the incidence of Type 1 diabetes as a clinical manifestation of APECED in different populations highlighting the peculiar genetic and immunological features of the disease when occurring in the context of this syndrome.

    Full Text Available Abstract Oral-Facial-Digital Syndrome type VI (OFD VI represents a rare phenotypic subtype of Joubert syndrome and related disorders (JSRD. In the original report polydactyly, oral findings, intellectual disability, and absence of the cerebellar vermis at post-mortem characterized the syndrome. Subsequently, the molar tooth sign (MTS has been found in patients with OFD VI, prompting the inclusion of OFD VI in JSRD. We studied the clinical, neurodevelopmental, neuroimaging, and genetic findings in a cohort of 16 patients with OFD VI. We derived the following inclusion criteria from the literature: 1 MTS and one oral finding and polydactyly, or 2 MTS and more than one typical oral finding. The OFD VI neuroimaging pattern was found to be more severe than in other JSRD subgroups and includes severe hypoplasia of the cerebellar vermis, hypoplastic and dysplastic cerebellar hemispheres, marked enlargement of the posterior fossa, increased retrocerebellar collection of cerebrospinal fluid, abnormal brainstem, and frequently supratentorial abnormalities that occasionally include characteristic hypothalamic hamartomas. Additionally, two new JSRD neuroimaging findings (ascending superior cerebellar peduncles and fused thalami have been identified. Tongue hamartomas, additional frenula, upper lip notch, and mesoaxial polydactyly are specific findings in OFD VI, while cleft lip/palate and other types of polydactyly of hands and feet are not specific. Involvement of other organs may include ocular findings, particularly colobomas. The majority of the patients have absent motor development and profound cognitive impairment. In OFD VI, normal cognitive functions are possible, but exceptional. Sequencing of known JSRD genes in most patients failed to detect pathogenetic mutations, therefore the genetic basis of OFD VI remains unknown. Compared with other JSRD subgroups, the neurological findings and impairment of motor development and cognitive functions in OFD

    Full Text Available Abstract Overweight and obesity in youth is a worldwide public health problem. Overweight and obesity in childhood and adolescents have a substantial effect upon many systems, resulting in clinical conditions such as metabolic syndrome, early atherosclerosis, dyslipidemia, hypertension and type 2 diabetes (T2D. Obesity and the type of body fat distribution are still the core aspects of insulin resistance and seem to be the physiopathologic links common to metabolic syndrome, cardiovascular disease and T2D. The earlier the appearance of the clustering of risk factors and the higher the time of exposure, the greater will be the chance of developing coronary disease with a more severe endpoint. The age when the event may occur seems to be related to the presence and aggregation of risk factors throughout life. The treatment in this age-group is non pharmacological and aims at promoting changes in lifestyle. However, pharmacological treatments are indicated in special situations. The major goals in dietary treatments are not only limited to weight loss, but also to an improvement in the quality of life. Modification of risk factors associated to comorbidities, personal satisfaction of the child or adolescent and trying to establish healthy life habits from an early age are also important. There is a continuous debate on the best possible exercise to do, for children or adolescents, in order to lose weight. The prescription of physical activity to children and adolescents requires extensive integrated work among multidisciplinary teams, patients and their families, in order to reach therapeutic success. The most important conclusion drawn from this symposium was that if the growing prevalence of overweight and obesity continues at this pace, the result will be a population of children and adolescents with metabolic syndrome. This would lead to high mortality rates in young adults, changing the current increasing trend of worldwide longevity

    Full Text Available Abstract Background Spinal deformities in Ehlers-Danlos syndrome are usually progressive and may require operative treatment. There is limited number of studies describing late results of surgery in this disease. Methods This is a retrospective study of the records of 11 patients with Ehlers-Danlos syndrome type IV, treated surgically between 1990 and 2007. All patients underwent surgical treatment for spinal deformity. Duration of operation, type of instrumentation, intraoperative blood loss, complications and number of additional surgeries were noted. Radiographic measurement was performed on standing AP and lateral radiographs acquired before surgery, just after and at final follow up. Results The mean follow up period was 5.5 ± 2.9 years (range 1-10 years. The mean preoperative thoracic and lumbar curve were 109.5 ± 19.9° (range 83° - 142° and 75.6 ± 26.7° (range 40° - 108° respectively. Posterior spine fusion alone was performed on 6 patients and combined anterior and posterior fusion (one- or two stage on 5 cases. Posterior segmental spinal instrumentation was applied with use of hooks, screws and wires. The mean postoperative thoracic and lumbar curve improved to 79.3 ± 16.1° (range 56° - 105° and 58.5 ± 27.7° (range 10° - 95° respectively, with a slight loss of correction during follow up. The average thoracic and lumbar correction was 26.4 ± 14.9% (range 5.3 - 50.4% and 26.3 ± 21.2% (range 7.9 - 75%. Postoperatively, the mean kyphosis was 79.5 ± 40.3° (range 21° -170°, and lordosis was 50.8 ± 18.6° (range 20° -79°. Hyperkyphosis increased during follow up while lordosis remained stable. Mean Th12-L2 angle was -3.5 ±9.9° (range -19° - 15° postoperatively and did not change significantly during follow up. Conclusions Huge spinal deformities in patients with Ehlers-Danlos syndrome require complex and extensive surgery. There is a big risk of sagittal imbalance in this group.

    Typical iliac vein compression syndrome (IVCS) is characterized by compression of left common iliac vein (LCIV) by the overlying right common iliac artery (RCIA). We described an underestimated type of IVCS with dual compression by right and left common iliac arteries (LCIA) simultaneously. Thirty-one patients with IVCS were retrospectively included. All patients received trans-catheter venography and computed tomography (CT) examinations for diagnosing and evaluating IVCS. Late venography and reconstructed CT were used for evaluating the anatomical relationship among LCIV, RCIA and LCIA. Imaging manifestations as well as demographic data were collected and evaluated by two experienced radiologists. Sole and dual compression were found in 32.3% (n = 10) and 67.7% (n = 21) of 31 patients respectively. No statistical differences existed between them in terms of age, gender, LCIV diameter at the maximum compression point, pressure gradient across stenosis, and the percentage of compression level. On CT and venography, sole compression was commonly presented with a longitudinal compression at the orifice of LCIV while dual compression was usually presented as two types: one had a lengthy stenosis along the upper side of LCIV and the other was manifested by a longitudinal compression near to the orifice of external iliac vein. The presence of dual compression seemed significantly correlated with the tortuous LCIA (p = 0.006). Left common iliac vein can be presented by dual compression. This type of compression has typical manifestations on late venography and CT.

    Antibodies against glutamic acid decarboxylase (GAD) are involved in the pathophysiology of stiff-person syndrome (SPS) and type 1 diabetes. GAD catalyses the conversion of glutamate to gamma-aminobutyric acid (GABA). GABA acts as a neurotransmitter between neurones, while in pancreatic beta cells it plays an integral role in normal insulin secretion, hence the clinical presentation of muscular spasms in SPS and insulin deficiency in diabetes. Despite this apparent major overlap in pathophysiology, SPS only rarely occurs in individuals with type 1 diabetes. We report the case of a 41-year-old man presenting with a simultaneous diagnosis of both these conditions. His case is unusual in that it is the first reported case in the literature of these conditions occurring in someone with celiac disease (CD) and dermatitis herpetiformis. We discuss why SPS and type 1 diabetes co-exist in only a minority of cases and speculate on the underlying mechanism of the association with CD and dermatitis herpetiformis in our patient.

    Full Text Available Autosomal dominant hyper IgE syndrome (AD-HIES is a primary immunodeficiency caused by a loss-of-function mutation in the Signal Transducer and Activator of Transcription 3 (STAT3. This immune disorder is clinically characterized by increased susceptibility to cutaneous and sinopulmonary infections, in particular with Candida and Staphylococcus aureus. It has recently been recognized that the skin microbiome of patients with AD-HIES is altered with an overrepresentation of certain Gram-negative bacteria and Gram-positive staphylococci. However, these alterations have not been characterized at the species- and strain-level. Since S. aureus infections are influenced by strain-specific expression of virulence factors, information on colonizing strain characteristics may provide insights into host-pathogen interactions and help guide management strategies for treatment and prophylaxis. The aim of this study was to determine whether the immunodeficiency of AD-HIES selects for unique strains of colonizing S. aureus. Using multi-locus sequence typing (MLST, protein A (spa typing, and PCR-based detection of toxin genes, we performed a detailed analysis of the S. aureus isolates (n = 13 found on the skin of twenty-one patients with AD-HIES. We found a low diversity of sequence types, and an abundance of strains that expressed methicillin resistance, Panton-Valentine leukocidin (PVL, and staphylococcal enterotoxins K and Q (SEK, SEQ. Our results indicate that patients with AD-HIES may often carry antibiotic-resistant strains that harbor key virulence factors.

    Full Text Available One of the important problems in modern dentistry is the study of jaw bone changes associated with type II diabetes. The aim of this study is to evaluate the influence of osteopenic syndrome on osseointegration when using dental implants in patients with type II diabetes. 40 patients with type II diabetes have been evaluated and assigned to two different groups based on the duration of the disease. Including criteria in patients with compensated diabetes were fasting glucose test results <6 mM/l and glycohemoglobin concentration ≤6%. All patients have been evaluated by means of dual energy X-ray absorptiometry on Discovery W densitometer by HOLOGIC. Laboratory blood markers have been used to assess the rate of metabolic processes. 43 implants have been fixed in both groups and maxillary sinus lifting has been applied in 4 cases. No immediate or late post -operative complications have been registered. In cases of disease duration over 5 years and presence of osteopenia the period of surgical wound healing has been prolongated.

    Full Text Available Abstract Background Type 2 diabetes and the metabolic syndrome are associated with impaired diastolic function and increased heart failure risk. Animal models and autopsy studies of diabetic patients implicate myocardial fibrosis, cardiomyocyte hypertrophy, altered myocardial microvascular structure and advanced glycation end-products (AGEs in the pathogenesis of diabetic cardiomyopathy. We investigated whether type 2 diabetes and the metabolic syndrome are associated with altered myocardial structure, microvasculature, and expression of AGEs and receptor for AGEs (RAGE in men with coronary artery disease. Methods We performed histological analysis of left ventricular biopsies from 13 control, 10 diabetic and 23 metabolic syndrome men undergoing coronary artery bypass graft surgery who did not have heart failure or atrial fibrillation, had not received loop diuretic therapy, and did not have evidence of previous myocardial infarction. Results All three patient groups had similar extent of coronary artery disease and clinical characteristics, apart from differences in metabolic parameters. Diabetic and metabolic syndrome patients had higher pulmonary capillary wedge pressure than controls, and diabetic patients had reduced mitral diastolic peak velocity of the septal mitral annulus (E', consistent with impaired diastolic function. Neither diabetic nor metabolic syndrome patients had increased myocardial interstitial fibrosis (picrosirius red, or increased immunostaining for collagen I and III, the AGE Nε-(carboxymethyllysine, or RAGE. Cardiomyocyte width, capillary length density, diffusion radius, and arteriolar dimensions did not differ between the three patient groups, whereas diabetic and metabolic syndrome patients had reduced perivascular fibrosis. Conclusions Impaired diastolic function of type 2 diabetic and metabolic syndrome patients was not dependent on increased myocardial fibrosis, cardiomyocyte hypertrophy, alteration of the

    To summarize the Patho-typing and the clinical manifestation of biliary cast syndrome (BCS) in patients after orthotopic liver transplantation. The clinical manifestation, findings,therapeutic means and efficacy of 103 patients with biliary cast syndrome after orthotopic liver transplantation were retrospectively analyzed. According to the injury level of biliary duct epithelium, patients were divided into different groups. All cases were followed up for twelve months. The place, degree and time after operation would be recorded when non-anastomotic biliary stricture was found. There were 59 BCS cases in the general hospital of armed police force of China. The incidence rate of BCS was 9.1%. Many BCS patients showed symptoms such as jaundice, deep urine color, gray stools, itch of skin and fever. Some were asymptomatic. In laboratory test, the liver functional enzyme in serum were increased, the total white cell count in peripheral blood was increased either. Cholangiography via T tube of biliary tract might show filling defect. According to the change degree of the biliary tract tree, there were four types filling defect concluded from all the presentation in BCS patients. Solid obturation of biliary tract were found by the check with optical fiber choledochoscope in all BCS patients, necrosis of biliary tract epithelium were observed in partial BCS patients. According to the injury level of biliary duct epithelium (gradually aggravated), BCS patients were divided into six groups (type I, type II, type III, type IV, type V and type VI). Fourteen cases were found in type I and 18 in type II. No clinical symptom was found in these two groups, a few indicators in serum (alanine aminotransferase ALT, total bilirubin TBIL, direct bilirubin DBIL) were in normal range, and others (gamma-glutamyl transferase GGT, alkaline phosphatase ALP) were heightened in 5 patients. There was no biliary cast (BC) found anymore in the period of follow-up in two groups. No stricture was

    Circadian timing system is a highly conserved, ubiquitous molecular "clock" which creates internal circadian rhythmicity. Dysregulation of clock genes expression is associated with various diseases including immune dysregulation. In this study we investigated the circadian pattern of Clock-related genes in patients with polyglandular autoimmune syndrome type III (PAS type III). Nineteen patients diagnosed with PAS type III and 12 healthy controls were enrolled. mRNA and protein expression of Clock-related genes (CLOCK, BMAL1, ROR and Per-1,-2,-3), as well as the GR-a and the GILZ genes were determined by real-time quantitative PCR and western blot analysis from blood samples drawn at 8 pm and 8am. Serum cortisol and TSH, as well as plasma ACTH, were measured by chemiluminescence. There were no statistical significant differences in the metabolic profile, cortisol, ACTH and TSH levels between patients and controls. Patients with PAS type III expressed higher transcript levels of CLOCK, BMAL1 and Per-1 in the evening than in the morning (p = 0.03, p = 0.029, p = 0.013, respectively), while the ratios (R pm/am ) of GR-a, CLOCK, BMAL1, and Per-3 mRNA levels were statistically different between patients and controls. Cortisol circadian variation (F pm/am ) was positively correlated with GILZ mRNA circadian pattern (R pm/am ) in the patient group and with the GR-a mRNA (R pm/am ) in the control group. Our findings suggest that there is an aberrant circadian rhythm of Clock-related genes in patients with PAS type III. The disruption of the expression of 4 circadian Clock-related genes could indicate a possible association with the pathogenesis of the disease.

    Bladder pain syndrome/interstitial cystitis (BPS/IC) is identified based on subjective symptoms which lead to heterogeneous patient populations. Previous studies using gene expression arrays for BPS/IC with Hunner's lesions [European Society for the Study of Interstitial Cystitis (ESSIC) type 3C], a subtype of the condition discernible by cystoscopy, have revealed characteristic immune responses and urothelial abnormalities. This current study aimed to further characterize this subtype using a gene expression panel. We hypothesized that B-cell activation with high levels of urinary antibody concentration would be found. Cold-cup bladder biopsies, catheterized urine and blood were collected from 15 BPS/IC ESSIC type 3C patients, 11 non-inflammatory overactive bladder (OAB) patients and eight healthy controls. Gene expression in biopsies was quantified by real-time quantitative polymerase chain reaction (RT-qPCR), immunohistochemistry was performed on bladder tissue and urinary immunoglobulins G and A were quantified by enzyme-linked immunosorbent assay. Statistical analyses included the Kruskal-Wallis test for non-parametric data and post hoc tests identified differences between groups. High expression of T- and B-cell markers (CTLA4, CD20, CD79A, IGH@), low expression of urothelial markers (KRT20, UPK1B, UPK3A), focal lymphoid aggregates in the submucosa and high immunoglobulin concentration in urine were found exclusively in BPS/IC ESSIC type 3C patients. Results for OAB were in intermediate ranges between the other two groups and UPK1B even reached significantly lower expression when compared to healthy controls. BPS/IC ESSIC type 3C is characterized by a local adaptive immune response with elevated urinary antibody concentrations. Quantification of urinary immunoglobulin levels could be used for a non-invasive diagnosis of BPS/IC ESSIC type 3C.

    Obesity-fuelled metabolic syndrome and diabetes is now a global epidemic. There is increasing evidence that these and other chronic conditions have common inflammatory antecedents. There is an interest in nutritionally based anti-inflammatory treatments for type 2 diabetes and metabolic syndrome. The aim of this review is to examine the evidence from a 5-year period; 2011-2016, for nutritionally based anti-inflammatory treatments for the Metabolic Syndrome and Type 2 Diabetes Mellitus. A literature search produced a total number of 1377 records, of which 26 papers were evaluated. Literature was analysed and tabulated according to date, outcome measures and results. The evidence is strong for use of polyphenolic compounds, fish oils and vitamins in reducing inflammation biomarkers, however the impact on metabolic control is less evident.

    Electrical transport in graphene has been of great interest in both fundamental and applied research. The impact of the substrate is critical to the operation of graphene field effect transistors (FET), which can modify several transport parameters as well as low frequency 1/f noise. Replacing the usual SiO2/Si++ substrate with SrTiO3[STO] having high dielectric constant, has opened up new possibilities, leading to large doping, higher mobility, and also hysteretic transfer characteristics for memory applications. We have studied 1/f noise in dual-gated single layer graphene (SLG) FET sandwiched between STO (substrate) and mechanically exfoliated hexagonal boron-nitride (dielectric for the top gate). The area normalized noise amplitude of SLG on STO followed an unexpected `W'-shape dependence of gate-bias with the central peak at Dirac point in conflict with the usual `V', `M' or ` Λ'-type dependence of SLG noise on SiO2. We discuss possible microscopic mechanisms for such behavior, considering the role of puckering of oxygen atoms introducing inward dipole moments that can form a new source of electrostatically tunable scattering mechanism at the graphene-STO interface.

    Ehlers-Danlos syndrome type IV is an autosomal dominant connective tissue disease. Mutations in COL3A1 have been identified to underlie this disease; however, to the best of our knowledge, no COL3A1 mutations have been reported in Ehlers-Danlos syndrome type IV patients with an ascending aortic aneurysm. In order to develop further understanding of COL3A1 mutations, an Ehlers-Danlos syndrome type IV patient diagnosed with an ascending aortic aneurysm and a familial history of sudden mortality was analyzed. Genomic DNA was isolated from the peripheral blood of the patient and his family members. All coding exons of eight aneurysm-related genes (FBN1, TGFBR1, TGFBR 2, MYH11, ACTA2, SLC2A10, NOTCH1 and COL3A1) were amplified using polymerase chain reaction (PCR). The PCR products were sequenced with the ABI 3100 Genetic Analyzer, and a mutation was predicted and identified using Polyphen-2, SIFT and Mutation Taster. The novel mutation was identified as c.2950G>A in COL3A1, which results in p.G984R. All three programs predicted this mutation to be deleterous to the protein function. The novel mutation identified in this study is potentially responsible for Ehlers-Danlos syndrome type IV in this patient, and expands the spectrum of COL3A1 mutations.

    Type B insulin resistance syndrome is a rare disease characterized by refractory transient hyperglycaemia and severe insulin resistance associated with circulating anti-insulin receptor antibodies. A standardized treatment regimen for type B insulin resistance syndrome has yet to be established. We report the case of a 64-year-old man undergoing haemodialysis for antineutrophil cytoplasmic antibody-associated vasculitis and diabetic nephropathy, who developed rapid onset of hyperglycaemia (glycated albumin 52.1%). Type B insulin resistance syndrome was diagnosed, on the basis of positivity for anti-insulin receptor antibodies and the man's autoimmune history of antineutrophil cytoplasmic antibody-associated vasculitis and idiopathic thrombocytopenic purpura. Although severe hyperglycaemia persisted in spite of corticosteroids and high-dose insulin therapy, rituximab treatment resulted in remarkable improvement of the man's severe insulin resistance and disappearance of anti-insulin receptor antibodies without any adverse effects. According to a literature review of 11 cases in addition to the present case, rituximab appears to be a safe and effective strategy for the treatment of corticosteroid-resistant type B insulin resistance syndrome. © 2017 Diabetes UK.

    Ehlers-Danlos syndrome (EDS) is an inherited disease characterized by defects in various collagens or their post translational modification, with an incidence estimated at 1 in 5000. Performance of peripheral nerve block in patients with EDS is controversial, due to easy bruising and hematoma formation after injections as well as reports of reduced block efficacy. The objective of this study was to review the charts of EDS patients who had received peripheral nerve block for any evidence of complications or reduced efficacy. Case series, chart review. Academic medical center. Patients with a confirmed or probable diagnosis of EDS who had received a peripheral nerve block in the last 3 years were identified by searching our institutions electronic medical record system. The patients were classified by their subtype of EDS. Patients with no diagnosed subtype were given a probable subtype based on a chart review of the patient's symptoms. Patient charts were reviewed for any evidence of complications or reduced block efficacy. A total of 21 regional anesthetics, on 16 unique patients were identified, 10 of which had a EDS subtype diagnosis. The majority of these patients had a diagnosis of hypermobility-type EDS. No block complications were noted in any patients. Two block failures requiring repeat block were noted, and four patients reported uncontrolled pain on postoperative day one despite successful placement of a peripheral nerve catheter. Additionally, blocks were performed without incident in patients with classical-type and vascular-type EDS although the number was so small that no conclusions can be drawn about relative safety of regional anesthesia in these groups. This series fails to show an increased risk of complications of peripheral nerve blockade in patients with hypermobility-type EDS. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Type III Bartter syndrome (BS is an autosomal recessive renal tubule disorder caused by loss-of-function mutations in the CLCNKB gene, which encodes the chloride channel protein ClC-Kb. In this study, we carried out a complete clinical and genetic characterization in a cohort of 30 patients, one of the largest series described. By comparing with other published populations, and considering that 80% of our patients presented the p.Ala204Thr Spanish founder mutation presumably associated with a common phenotype, we aimed to test the hypothesis that allelic differences could explain the wide phenotypic variability observed in patients with type III BS.Clinical data were retrieved from the referral centers. The exon regions and flanking intronic sequences of the CLCNKB gene were screened for mutations by polymerase chain reaction (PCR followed by direct Sanger sequencing. Presence of gross deletions or duplications in the region was checked for by MLPA and QMPSF analyses.Polyuria, polydipsia and dehydration were the main common symptoms. Metabolic alkalosis and hypokalemia of renal origin were detected in all patients at diagnosis. Calciuria levels were variable: hypercalciuria was detected in 31% of patients, while 23% had hypocalciuria. Nephrocalcinosis was diagnosed in 20% of the cohort. Two novel CLCNKB mutations were identified: a small homozygous deletion (c.753delG in one patient and a small deletion (c.1026delC in another. The latter was present in compound heterozygosis with the already previously described p.Glu442Gly mutation. No phenotypic association was obtained regarding the genotype.A poor correlation was found between a specific type of mutation in the CLCNKB gene and type III BS phenotype. Importantly, two CLCNKB mutations not previously described were found in our cohort.

    Full Text Available Gitelman’s syndrome (GS is characterized by hypokalemia, hypomagnesaemia, hypocalciuria, metabolic alkalosis, and neurological symptoms. The association of GS with type 1 diabetes is rare, described only in a few case reports. We report a patient with an unusual combination of GS and type 1 diabetes mellitus with erythrocytosis. A 26-year-old male with GS and type 1 diabetes, who was on intensive insulin therapy with poor compliance, presented with the complaint of headache. On physical examination, his blood pressure was 120/70 mmHg and there was no neurological deficit or proximal muscle weakness. He had no previous medical history of obstructive sleep apnea, heart or lung disease. He had negative smoking history. His laboratory tests revealed erythrocytosis with a hemoglobin level of 18.9 g/dL (13.6-17.2 g/dL and a hematocrit level of 54.8% (39.5-50.3%. Cranial magnetic resonance imaging was normal. He had no evidence of hypovolemia. Hematological workout excluded polycythemia vera and chronic myeloid neoplasm. A bone marrow aspiration revealed a hypercellular marrow with increased erythroid precursors, megakaryocytes and granulocytes. The reticulin stain grade was zero. There was no iron accumulation with iron stain. There was no radiologic evidence of any kind of erythropoietin-producing tumors. His echocardiography was normal. Serum insulin-like growth factor-1 levels and endogenous androgens were within normal limits. After 2 therapeutic phlebotomies, his symptoms improved and his hemoglobin was 16.1 mg/dL. Our patient, besides having GS and type 1 diabetes, was complicated with idiopathic erythrocytosis, all having deleterious effects on hemodynamic status of the patient.

    This office field study investigated the effects of different types of spectacle lenses habitually worn by computer users with presbyopia and in the beginning stages of presbyopia. Computer vision syndrome was assessed through reported complaints and ergonomic conditions. A questionnaire regarding the type of habitually worn near-vision lenses at the workplace, visual conditions and the levels of different types of complaints was administered to 175 participants aged 35 years and older (mean ± SD: 52.0 ± 6.7 years). Statistical factor analysis identified five specific aspects of the complaints. Workplace conditions were analysed based on photographs taken in typical working conditions. In the subgroup of 25 users between the ages of 36 and 57 years (mean 44 ± 5 years), who wore distance-vision lenses and performed more demanding occupational tasks, the reported extents of 'ocular strain', 'musculoskeletal strain' and 'headache' increased with the daily duration of computer work and explained up to 44 per cent of the variance (rs = 0.66). In the other subgroups, this effect was smaller, while in the complete sample (n = 175), this correlation was approximately rs = 0.2. The subgroup of 85 general-purpose progressive lens users (mean age 54 years) adopted head inclinations that were approximately seven degrees more elevated than those of the subgroups with single vision lenses. The present questionnaire was able to assess the complaints of computer users depending on the type of spectacle lenses worn. A missing near-vision addition among participants in the early stages of presbyopia was identified as a risk factor for complaints among those with longer daily durations of demanding computer work. © 2015 The Authors.

    Neurofibromatosis-Noonan syndrome (NFNS) is a rare condition with clinical features of both neurofibromatosis type 1 (NF1) and Noonan syndrome (NS). All three syndromes belong to the RASopathies, which are caused by dysregulation of the RAS-MAPK pathway. The major gene involved in NFNS is NF1, but co-occurring NF1 and PTPN11 mutations in NFNS have been reported. Knowledge about possible involvement of additional RASopathy-associated genes in NFNS is, however, very limited. We present a comprehensive clinical and molecular analysis of eight affected individuals from three unrelated families displaying features of NF1 and NFNS. The genetic etiology of the clinical phenotypes was investigated by mutation analysis, including NF1, PTPN11, SOS1, KRAS, NRAS, BRAF, RAF1, SHOC2, SPRED1, MAP2K1, MAP2K2, and CBL. All three families harbored a heterozygous NF1 variant, where the first family had a missense variant, c.5425C>T;p.R1809C, the second family a recurrent 4bp-deletion, c.6789_6792delTTAC;p.Y2264Tfs*6, and the third family a splice-site variant, c.2991-1G>A, resulting in skipping of exon 18 and an in-frame deletion of 41 amino acids. These NF1 variants have all previously been reported in NF1 patients. Surprisingly, both c.6789_6792delTTAC and c.2991-1G>A are frequently associated with NF1, but association to NFNS has, to our knowledge, not previously been reported. Our results support the notion that NFNS represents a variant of NF1, genetically distinct from NS, and is caused by mutations in NF1, some of which also cause classical NF1. Due to phenotypic overlap between NFNS and NS, we propose screening for NF1 mutations in NS patients, preferentially when café-au-lait spots are present. © 2013 Wiley Periodicals, Inc.

    This study investigates relationships between methyl-CpG-binding protein 2 gene (MECP2) mutation type and speech-language abilities in girls with Rett syndrome. Cross-sectional data on 766 girls, aged 15 years and under, with genetically confirmed Rett syndrome was obtained from the Australian Rett Syndrome Database (ARSD) (n = 244) and the International Rett Syndrome Phenotype Database (InterRett) (n = 522). Relationships between MECP2 mutation type and age of regression in speech-language abilities, and the level of speech-language abilities before and after this regression were investigated. The females had a median age of 4.95 years in the ARSD and 5.25 years in InterRett. The majority (89%, 685/766) acquired speech-language abilities in the form of babble or words at some point in time. Of those who acquired babble or words, 85% (581/685) experienced a regression in these abilities. Those with a p.Arg133Cys mutation were the most likely to use one or more words, prior to (RRR = 3.45; 95% CI 1.15-10.41) and after (RRR = 5.99; 95% CI 2.00-17.92), speech-language regression. Girls with Rett syndrome vary in their use of speech and language, and in their experience of speech-language regression and these variations are partly explained by genotype. © 2014 Wiley Periodicals, Inc.

    Patients with Type 1 Diabetes (T1D) are at high risk of developing lacrimal gland dysfunction. We have developed a new model of human T1D using double-transgenic mice carrying HLA-DQ8 diabetes-susceptibility haplotype instead of mouse MHC-class II and expressing the human beta cell autoantigen Glutamic Acid Decarboxylase in pancreatic beta cells. We report here the development of dry eye syndrome (DES) after diabetes induction in our humanized transgenic model. Double-transgenic mice were immunized with DNA encoding human GAD65, either naked or in adenoviral vectors, to induce T1D. Mice monitored for development of diabetes developed lacrimal gland dysfunction. Animals developed lacrimal gland disease (classically associated with diabetes in Non Obese Diabetic [NOD] mice and with T1D in humans) as they developed glucose intolerance and diabetes. Animals manifested obvious clinical signs of dry eye syndrome (DES), from corneal erosions to severe keratitis. Histological studies of peri-bulbar areas revealed lymphocytic infiltration of glandular structures. Indeed, infiltrative lesions were observed in lacrimal/Harderian glands within weeks following development of glucose intolerance. Lesions ranged from focal lymphocytic infiltration to complete acinar destruction. We observed a correlation between the severity of the pancreatic infiltration and the severity of the ocular disease. Our results demonstrate development of DES in association with antigen-specific insulitis and diabetes following immunization with clinically relevant human autoantigen concomitantly expressed in pancreatic beta cells of diabetes-susceptible mice. As in the NOD mouse model and as in human T1D, our animals developed diabetes-associated DES. This specific finding stresses the relevance of our model for studying these human diseases. We believe our model will facilitate studies to prevent/treat diabetes-associated DES as well as human diabetes.

    Autonomic dysfunction contributes to health-related impairment of quality of life in the hypermobile type of Ehlers-Danlos syndrome (hEDS). Typical signs and symptoms include tachycardia, hypotension, gastrointestinal dysmotility, and disturbed bladder function and sweating regulation. Cardiovascular autonomic dysfunction may present as Orthostatic Intolerance, Orthostatic Hypotension, Postural Orthostatic Tachycardia Syndrome, or Neurally Mediated Hypotension. The incidence, prevalence, and natural history of these conditions remain unquantified, but observations from specialist clinics suggest they are frequently seen in hEDS. There is growing understanding of how hEDS-related physical and physiological pathology contributes to the development of these conditions. Evaluation of cardiovascular symptoms in hEDS should include a careful history and clinical examination. Tests of cardiovascular function range from clinic room observation to tilt-table assessment to other laboratory investigations such as supine and standing catecholamine levels. Non-pharmacologic treatments include education, managing the environment to reduce exposure to triggers, improving cardiovascular fitness, and maintaining hydration. Although there are limited clinical trials, the response to drug treatments in hEDS is supported by evidence from case and cohort observational data, and short-term physiological studies. Pharmacologic therapy is indicated for patients with moderate-severe impairment of daily function and who have inadequate response or tolerance to conservative treatment. Treatment in hEDS often requires a focus on functional maintenance. Also, the negative impact of cardiovascular symptoms on physical and psycho-social well-being may generate a need for a more general evaluation and on-going management and support. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    The consequences of the Ehlers-Danlos Syndrome hypermobility type (EDS-HT) affect many aspects of daily life. "Living with limitations" is a central theme in the life of patients affected by this heritable disorder of connective tissue. The aim of the present study was to explore the lived experiences of women with EDS-HT concerning diagnosis, influence on daily life and becoming and being a mother. A phenomenological-hermeneutical study, using in-depth interviews. Patients were selected by a purposive sampling strategy. This study shows that the EDS-HT syndrome affects daily life. Ten woman between 31 and 65 years were interviewed. They have between 2 and 5 children. The data analysis results in six themes. (1) Getting a diagnosis is a relief and supports the choice to become a mother; (2) EDS-HT causes emotional distress, imposes a physical burden and has a major impact on social behavior; (3) EDS-HT demands a restructuring of everyday activities; (4) Children's and mothers' expectations do not correspond; (5) Having a supportive social and physical environment is of major importance; (6) The presence of the child reduces the feeling of illness of the mother. The diagnosis of EDS-HT is a catalysing factor in the choice of whether or not to become a mother. EDS-HT has a huge impact on bodily functions, which in turn influences activities and participation. This study gives insight in the activities of daily life of persons with EDS-HT. Health care professionals can be of great importance to help patients in (re)organizing their lives according to the available energy and in supporting their choices. They can help defining goals and setting priorities in daily life. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To assess the prevalence of metabolic syndrome (MetS) among patients with type 1 diabetes mellitus(T1DM) and to look at prevalence of diabetes complications in T1DM with and without MetS. We studied 451 T1DM patients attending a tertiary diabetes centre in Chennai, South India. T1DM was diagnosed based on absence of beta cell reserve and requirement of insulin from the time of diagnosis. Data on clinical and biochemical characteristics as well as complications details to study the prevalence were also extracted from electronic records. T1DM patients were divided into those with and without MetS[diagnosed according to the harmonizing the metabolic syndrome criteria(IDF/NHLBI/AHA/WHF/IAS/IASO)]. The overall prevalence of MetS among T1DM was 22.2%(100/451). Patients with MetS were older, had longer diabetes duration, acanthosis nigricans, and increased serum cholesterol. In the unadjusted logistic regression analysis, retinopathy, nephropathy and neuropathy were associated with MetS. However after adjustment for age, gender, diabetes duration, HbA1C and BMI significant association was seen only between MetS and retinopathy [odds ratio (OR) 2.82, 95% CI 1.18-6.74, p = 0.020] and nephropathy [OR 4.92, 95% CI 2.59-9.33, p < 0.001]. Prevalence of MetS is high among Asian Indian T1DM patients, and its presence is associated with increased risk of diabetic retinopathy and nephropathy. Copyright © 2015 Elsevier Inc.

    Objective Usher's syndrome type II (USH2) is characterized by moderate to profound congenital hearing loss, later onset of retinitis pigmentosa, and normal vestibular function. Recently, a study investigating the vestibular function of USH2 patients demonstrated a pathologic response to vestibular tests. In this cross-sectional study we performed vestibular tests of a group patients with genetic diagnosis of USH2 syndrome to demonstrate if vestibular damage is present in USH2 patients. Study Design Cross-sectional study. Setting Tertiary referral center. Subjects and Methods Mutated genes of 7 patients with a clinical diagnosis of USH2 were evaluated. Vestibular function was investigated by audiometry, Fitzgerald-Hallpike caloric vestibular testing, cervical vestibular evoked myogenic potentials (C-VEMPs), ocular vestibular evoked myogenic potentials (O-VEMPs), and video head impulse test (v-HIT). Results Genetic tests confirmed the USH2 diagnosis in 5 of 7 patients examined, with 1 patient reporting a unique mutation on genetic tests. Four (80%) of the 5 patients with a genetic diagnosis of USH2 showed pathological O-VEMPs. Two patients (40%) reported bilateral absent or abnormal values of C-VEMPs. The superior semicircular canal presented a significant deficit in 2 (40%) patients. The same 2 cases showed a pathologic response of the v-HIT of the horizontal semicircular canal. Finally, the posterior semicircular canal presented a significant deficit in 4 (40.0%) patients. Conclusion A vestibular evaluation with vestibular evoked myogenic potentials and v-HIT seems to identify latent damage to the vestibular receptors of USH2 patients.

    The Ehlers-Danlos syndrome (EDS) is a heterogeneous group of heritable disorders of connective tissue, affecting skin, ligaments, joints, blood vessels, and internal organs. The main general findings are hyperextensibility and bruisability of the skin, with abnormal scarring, and joint laxity. On the basis of clinical, genetic, and biochemical findings, EDS can be classified today into at least 10 different types. Among them, EDS type VI (MIM 225400) is characterized by marked muscular hypotonia from birth; kyphoscoliosis, often present at birth and progressing to a severe form; marfanoid habitus; eye involvement, often with microcornea and a tendency of the eyeballs to rupture after minor trauma; osteoporosis; and sometimes spontaneous rupture of arteries. The disorder is due to a deficiency of lysyl hydroxylase (E.C.1.14.11.4), inherited in an autosomal recessive mode. Traditionally, the clinical diagnosis is confirmed by an insufficiency of hydroxylysine, on analysis of hydrolyzed dermis and/or reduced enzyme activity in cultured skin fibroblasts. 12 refs., 1 tab.

    Full Text Available Ehlers-Danlos syndrome, vascular type (vEDS (MIM #130050 is an autosomal dominant disorder caused by mutation in the type III collagen gene, COL3A1, leading to fragility of blood vessels, bowel and uterus that leads to spontaneous rupture. We report a previously undiagnosed vEDS patient with bowel complications. A 20-year-old female patient was referred to our hospital with abdominal pain. Computed tomography showed notable dilatation of the sigmoid colon with intraperitoneal fluid. Laparotomy revealed dilatation of the sigmoid colon, breakdown of serosa and muscularis propria of the sigmoid colon with impending perforation, and intra-abdominal hemorrhage caused by breakdown of the mesenterium. Resection of the sigmoid colon with Hartmann's pouch and an end colostomy were performed. Physical examination showed joint hypermobility, translucent skin with venous prominence and facial structure abnormalities. Genetic analysis using cDNA extracted from the patient's fibroblasts by reverse transcriptase polymerase chain reaction direct sequencing showed a missense mutation within the triple helix region of COL3A1 (c.2150 G>A; Gly717Asp.

    Metabolic Syndrome (MS) is related to insulin resistance and to type 2 diabetes mellitus. However, patients with type 1 diabetes mellitus (T1DM) may also develop this condition. To determine the prevalence of MS in patients with T1DM. Cross sectional study of 52 patients with T1DM aged 18 to 72 years (27 females) with 5 years or more since their diagnosis of T1DM. MS presence was defined according to the Adult Treatment Panel III criteria. Acanthosis nigricans (AN), waist circumference (WC), daily dose of insulin, glycosylated hemoglobin (HbAlc) and micro albuminuria were evaluated. The prevalence of MS was 25% (13/52). A higher daily dose of insulin was required in patients with MS (p =0.018), with AN (p =0.022) and with obesity (p =0.002). A direct association between WC and the dose of insulin was observed (r =0.51; p <0.0001). No association was observed between MS, time of evolution of T1DM, HbAlc or micro albuminuria. In this group of patients with T1DM there was a high prevalence of MS.

    To understand type B insulin resistance syndrome (B-IRS) by reviewing 3 cases from our center and cases from literatures. The clinical characteristics, diagnosis, treatment and follow-up data of the 3 patients with B-IRS were evaluated. All the 3 patients were middle-aged women with severe hyperglycemia or paradoxical hypoglycemia. The clinical findings were as follows. (1)B-IRS was associated with several autoimmune diseases such as systemic lupus erythematosus (SLE) and sclerosis. (2) The metabolic abnormalities of B-IRS include weight loss, severe hyperinsulinemia, high level of adiponectin, and low level of insulin-like growth factor type 1(IGF-1) and TG. (3)B-IRS was characterized with nonspecific serological disorders (such as leukopenia, thrombocytopenia and hypoalbuminemia) and changes (decreased complements and elevated IgG and/or IgA), and with specific immunological abnormalities[such as high titer of antinuclear antibody(ANA), positive in anti-SSA, anti-SSB and anti-dsDNA antibodies). Positive in anti-insulin receptor antibody was of diagnostic value but not necessary. (4) Treatments include insulin in combination with immunosuppressive therapy. Patients with H. pylori (Hp) infection may be benefit with eradication therapy. B-IRS is rare but not difficult to identify. Treatments include therapy of the underlying diseases and high dose of insulin.

    Full Text Available Abstract Introduction Vascular-type Ehlers-Danlos syndrome is an autosomal dominant disease that causes arterial spurting, intestinal perforation, uterine rupture and hemopneumothorax due to decreased production of type III collagen. The average age at death is 48 years old, and it is considered to be the most severe form of Ehlers-Danlos syndrome. We report the case of a 64-year-old Japanese woman and her 38-year-old daughter who were diagnosed with this disease. Case presentation A 64-year-old Japanese woman was referred to our hospital because of right anterior chest pain following cough and pharyngeal discomfort. Pleurisy was suspected due to the presence of right pleural effusion, so the next day she was referred to our department, where a detailed examination led to the diagnosis of hemothorax. The bleeding that caused the right hemothorax was difficult to control, so our patient was transferred to the Department of Thoracic Surgery for hemostasis control. Our patient’s personal history of uterine hemorrhage and skin ulcers, as well as the finding of skin fragility during surgery, were indicative of a weak connective tissue disease; therefore, after improvement of the hemothorax, a genetic analysis was performed. This revealed a heterozygous missense mutation in COL3A1, c.2411 G>T p.Gly804Val (exon 36. A detailed investigation conducted at a later date revealed that her daughter also had the same genetic mutation. This led to the diagnosis of vascular-type Ehlers-Danlos syndrome characterized by a new gene mutation. Conclusion We report a new genetic mutation associated with vascular-type Ehlers-Danlos syndrome. We present the clinical and imaging findings, and the disease and treatment course in this patient. We believe this information will be important in treating future cases of vascular-type Ehlers-Danlos syndrome in patients with this mutation.

    The vascular type of Ehlers–Danlos syndrome (EDS), EDS type IV (Online Mendelian Inheritance in Man [MIM] #130050) is characterized by thin, translucent skin, easy bruising, and arterial, intestinal, and/or uterine fragility during pregnancy, which may lead to sudden death. It is an autosomal dominant inherited disorder caused by type III procollagen gene (COL3A1: MIM #120180) mutations. Approximately 50% of the COL3A1 mutations are inherited from an affected parent, and 50% are de novo mutations. Each child of an affected individual has a 50% chance of inheriting the mutation and developing the disorder. Pregnant women with vascular EDS are at an increased risk of uterine and arterial rupture during the peripartum period, with high maternal morbidity and mortality rates. We report the first case of an asymptomatic 35-year-old woman at a risk of complications of vascular EDS who underwent presymptomatic evaluation during pregnancy. The sequencing results of both her brother and mother had a one-base-pair deletion, resulting in Glutamate at position 730 changing to Lysine and causing a frame shift and premature termination codon at 61 amino acids from the mutation position (p. Glu730Lysfs*61) on exon 32 of COL3A1. This deletion caused frameshift, leading to a premature termination codon (TAG) at 181 nucleotides downstream in exon 35, which could not be detected by previous total RNA (ribonucleic acid) method. Thus, she was at risk of complications of vascular EDS, and diagnostic testing was employed at 8 weeks of pregnancy to minimize the risk of developing vascular EDS-related complications. The negative presymptomatic diagnostic result allowed the patient to choose normal delivery at term. Vascular EDS is a serious disorder, with high mortality, especially in high-risk women with vascular EDS during pregnancy. The presymptomatic genetic testing of vascular EDS during pregnancy for a high-risk family can help with the early establishment of preventive measures

    To explore the molecular mechanism of Waardenburg syndrome type II (WS2) resulting from SOX10 gene mutation E248fs through in vitro experiment. 293T cells were transiently transfected with wild type (WT) SOX10 and mutant type (MT) E248fs plasmids. The regulatory effect of WT/MT SOX10 on the transcriptional activity of MITF gene and influence of E248fs on WT SOX10 function were determined with a luciferase activity assay. The DNA binding capacity of the WT/MT SOX10 with the promoter of the MITF gene was determined with a biotinylated double-stranded oligonucleotide probe containing the SOX10 binding sequence cattgtc to precipitate MITF and E248fs, respectively. The stability of SOX10 and E248fs were also analyzed. As a loss-of-function mutation, the E248fs mutant failed to transactivate the MITF promoter as compared with the WT SOX10 (P<0.01), which also showed a dominant-negative effect on WT SOX10. The WT SOX10 and E248fs mutant were also able to bind specifically to the cattgtc motif in the MITF promoter, whereas E248fs had degraded faster than WT SOX10. Despite the fact that the E248fs has a dominant-negative effect on SOX10, its reduced stability may down-regulate the transcription of MITF and decrease the synthesis of melanin, which may result in haploinsufficiency of SOX10 protein and cause the milder WS2 phenotype.

    Improvements in diagnostic methods and greater genetic awareness have brought remarkable progress in the recognition of monogenic forms of diabetes, including Wolfram syndrome (WFS). WFS is diagnosed based on clinical criteria of coexistence of diabetes mellitus and optic atrophy, and confirmed by molecular analysis; however, the condition is still sometimes misdiagnosed. To begin to understand the reasons for misdiagnosis, we conducted a retrospective analysis of WFS patients who were originally misdiagnosed. The medical histories of 13 pediatric patients with clinical misdiagnosis of type 1 diabetes and early chronic complications made in the years 1995-2010 and who were subsequently correctly diagnosed with WFS based on genetic testing in 2008-2011 were analyzed. The average age of the patients at diabetes onset was 5 (4.4-6.3) years, and the mean HbA1c level at diagnosis was 9.1±2.3%. Initially, all of these patients were treated as having type 1 diabetes with progressive visual impairment despite good metabolic control (mean HbA1c 7.5±1.3%). Diagnosis of optic atrophy was made at an average age of 9 (5.9-11.5) years, which corresponds to 4 years after diabetes recognition (p=0.002). At the time of genetic analysis, the average age of the patients was 16 (12-18.7) years, which corresponds to 7 years after recognition of coexistence of diabetes mellitus and optic atrophy (p=0.007). Delays of at least 7 years occurred before recognition of WFS among a cohort of pediatric patients with diabetes. All patients with WFS were primarily misdiagnosed as having type 1 diabetes. © J. A.

    Full Text Available Many studies have focused on Type A and Type D personality types in the context of cardiovascular diseases (CVDs, but nothing is known about how these personality types combine to create new profiles. The present study aimed to develop a typology of Type A and Type D personality in two groups of patients affected by and at risk for coronary disease. The study involved 711 patients: 51.6% with acute coronary syndrome, 48.4% with essential hypertension (mean age = 56.4 years; SD = 9.7 years; 70.7% men. Cluster analysis was applied. External variables, such as socio-demographic, psychological, lifestyle, and clinical parameters, were assessed. Six groups, each with its own unique combined personality profile scores, were identified: Type D, Type A-Negatively Affected, Not Type A-Negatively Affected, Socially Inhibited-Positively Affected, Not Socially Inhibited, and Not Type A-Not Type D. The Type A-Negatively Affected cluster and, to a lesser extent, the Type D cluster, displayed the worst profile: namely higher total cardiovascular risk index, physical inactivity, higher anxiety and depression, and lower self-esteem, optimism, and health status. Identifying combined personality profiles is important in clinical research and practice in cardiovascular diseases. Practical implications are discussed.

    Full Text Available Abstract Introduction Colonoscopic perforation is a rare but serious complication of colonoscopy. Factors known to increase the risk of perforation include colonic strictures, extensive diverticulosis, and friable tissues. We describe the case of a man who was found to have perforation of the sigmoid colon secondary to an undiagnosed connective tissue disorder (Ehlers-Danlos syndrome type IV while undergoing surveillance for hereditary non-polyposis colorectal cancer. Case presentation A 33-year-old Caucasian man presented to our hospital with an acute abdomen following a colonoscopy five days earlier as part of hereditary non-polyposis colorectal cancer screening. His medical history included bilateral clubfoot. His physical examination findings suggested left iliac fossa peritonitis. A computed tomographic scan revealed perforation of the sigmoid colon and incidentally a right common iliac artery aneurysm as well. Hartmann's procedure was performed during laparotomy. The patient recovered well post-operatively and was discharged. Reversal of the Hartmann's procedure was performed six months later. This procedure was challenging because of dense adhesions and friable bowel. The histology of bowel specimens from this surgery revealed thinning and fibrosis of the muscularis externa. The patient was subsequently noted to have transparency of truncal skin with easily visible vessels. An underlying collagen vascular disorder was suspected, and genetic testing revealed a mutation in the collagen type III, α1 (COL3A1 gene, which is consistent with a diagnosis of Ehlers-Danlos syndrome type IV. Conclusions Ehlers-Danlos syndrome type IV, the vascular type, is a rare disorder caused by mutations in the COL3A1 gene on chromosome 2q31. It is characterized by translucent skin, clubfoot, and the potentially fatal complications of spontaneous large vessel rupture, although spontaneous uterine and colonic perforations have also been reported in the

    The p.Ala204Thr mutation (exon 7) of the CLCNKB gene is a "founder" mutation that causes most of type III Bartter syndrome cases in Spain. We performed genetic analysis of the CLCNKB gene, which encodes for the chloride channel protein ClC-Kb, in a cohort of 26 affected patients from 23 families. The diagnostic algorithm was: first, detection of the p.Ala204Thr mutation; second, detecting large deletions or duplications by Multiplex Ligation-dependent Probe Amplification and Quantitative Multiplex PCR of Short Fluorescent Fragments; and third, sequencing of the coding and flanking regions of the whole CLCNKB gene. In our genetic diagnosis, 20 families presented with the p.Ala204Thr mutation. Of those, 15 patients (15 families) were homozygous (57.7% of overall patients). Another 8 patients (5 families) were compound heterozygous for the founder mutation together with a second one. Thus, 3 patients (2 siblings) presented with the c. -19-?_2053+? del deletion (comprising the entire gene); one patient carried the p.Val170Met mutation (exon 6); and 4 patients (3 siblings) presented with the novel p.Glu442Gly mutation (exon 14). On the other hand, another two patients carried two novel mutations in compound heterozygosis: one presented the p.Ile398_Thr401del mutation (exon 12) associated with the c. -19-?_2053+? del deletion, and the other one carried the c.1756+1G>A splice-site mutation (exon 16) as well as the already described p.Ala210Val change (exon 7). One case turned out to be negative in our genetic screening. In addition, 51 relatives were found to be heterozygous carriers of the described CLCNKB mutations. In conclusion, different mutations cause type III Bartter syndrome in Spain. The high prevalence of the p.Ala204Thr in Spanish families thus justifies an initial screen for this mutation. However, should it not be detected further investigation of the CLCNKB gene is warranted in clinically diagnosed families. PMID:24058621

    To reconstruct the aortic root for aneurysm of the ascending aorta accompanied by aortic regurgitation, annuloaortic ectasia (AAE) and acute type-A dissection with root destruction, the Bentall operation using a prosthetic valve still is the standard procedure today. Valve-sparing procedures have actively been used for aortic root lesions, and have also been attempted in aortic root reconstruction for Marfan syndrome which may have abnormalities in the valve leaflets. We conducted a valve-sparing procedure in a female patient with Marfan syndrome who had AAE accompanied by type-A acute aortic dissection. The patient was a 37-year-old woman complaining of severe pain from the chest to the back. The limbs were long, and funnel breast was observed. Diastolic murmurs were heard. On chest computed tomography, a dissection cavity was present from the ascending aorta to the left common iliac artery, and the root dilated to 55 mm. Grade II aortic regurgitation was observed on ultrasound cardiography. Regarding her family history, her father had died suddenly at 54 years of age. She was diagnosed with type-A acute dissection concurrent with Marfan syndrome and AAE. The structure of the aortic valve was normal, and root reconstruction by a valve-sparing operation and total replacement of the aortic arch was conducted. On postoperative ultrasound cardiography, the aortic regurgitation was within the allowable range, and the shortterm postoperative results were good.

  12. Sleep apnea-hypopnea syndrome and type 2 diabetes. A reciprocal relationship?

    Epidemiological data suggest that sleep apnea-hypopnea syndrome (SAHS) is independently associated with the development of insulin resistance and glucose intolerance. Moreover, despite significant methodological limitations, some studies report a high prevalence of SAHS in patients with type 2 diabetes mellitus (DM2). A recent meta-analysis shows that moderate-severe SAHS is associated with an increased risk of DM2 (relative risk=1.63 [1.09 to 2.45]), compared to the absence of apneas and hypopneas. Common alterations in various pathogenic pathways add biological plausibility to this relationship. Intermittent hypoxia and sleep fragmentation, caused by successive apnea-hypopnea episodes, induce several intermediate disorders, such as activation of the sympathetic nervous system, oxidative stress, systemic inflammation, alterations in appetite-regulating hormones and activation of the hypothalamic-pituitary-adrenal axis which, in turn, favor the development of insulin resistance, its progression to glucose intolerance and, ultimately, to DM2. Concomitant SAHS seems to increase DM2 severity, since it worsens glycemic control and enhances the effects of atherosclerosis on the development of macrovascular complications. Furthermore, SAHS may be associated with the development of microvascular complications: retinopathy, nephropathy or diabetic neuropathy in particular. Data are still scant, but it seems that DM2 may also worsen SAHS progression, by increasing the collapsibility of the upper airway and the development of central apneas and hypopneas.

    To explore the association of sedentary life style with risk of metabolic syndrome (MS) and diabetes mellitus type 2(T2DM). A total of 6 016 local residents aged 18 years or older in Fujian province were recruited by multi-stage stratified cluster sampling method in 2010-2011. Data, including demographic information, physical activity and sedentary time were collected. Indices related to height, weight, waist circumference, blood pressure and blood lipid were determined while MS and T2DM were diagnosed by IDF (2005) and WHO (1999) criteria. Logistic regression was used to estimate the correlations between sedentary behavior and MS or T2DM. The prevalence rates of MS and T2DM were 19.0% and 8.0% respectively, in local residents aged 18 years or older, in Fujian province. The overall rate of sedentary behavior was 18.1%, with the mean sedentary time as 4.3 hours. Both data showed significantly differences (P sedentary time sedentary behavior was independently associated with an increased risk of MT group (OR = 1.82, 95% CI: 1.33-2.48, P sedentary behavior/sedentary time. MS and T2DM were associated with sedentary lifestyle, but these findings should be confirmed through further longitudinal studies.

    2017-04-01

    Constitutional mismatch repair (MMR) deficiency (CMMRD) is a rare childhood cancer susceptibility syndrome resulting from biallelic germline loss-of-function mutations in one of the MMR genes. Individuals with CMMRD have high risk to develop a broad spectrum of malignancies and frequently display features reminiscent of neurofibromatosis type 1 (NF1). Evaluation of the clinical findings of genetically proven CMMRD patients shows that not only multiple café-au-lait macules but also any of the diagnostic features of NF1 may be present in a CMMRD patient. This phenotypic overlap may lead to misdiagnosis of CMMRD patients as having NF1, which impedes adequate management of the patients and their families. The spectrum of CMMRD-associated childhood malignancies includes high-grade glioma, acute myeloid leukaemia or rhabdomyosarcoma, also reported as associated with NF1. Reported associations between NF1 and these malignancies are to a large extent based on studies that neither proved the presence of an NF1 germline mutation nor ruled-out CMMRD in the affected. Hence, these associations are challenged by our current knowledge of the phenotypic overlap between NF1 and CMMRD and should be re-evaluated in future studies. Recent advances in the diagnostics of CMMRD should render it possible to definitely state or refute this diagnosis in these individuals. © 2016 John Wiley & Sons A/S.

    To compare the clinical characteristics and prevalence of chronic complications in type 2 diabetes mellitus (T2DM) patients with various degrees of obstructive sleep apnea syndrome (OSAS). A total of 170 patients with T2DM and OSAS were enrolled in this study. These participants were divided into three groups with low, medium and high apnea-hypopnea index (AHI), respectively. The demographic characteristics, biochemical indicators and chronic complications of the patients in the three groups were compared. Multivariate Logistic regression analysis was performed to determine the associations between chronic complications and OSAS. The patients with severe OSAS had higher waist circumference ( P =0.045), higher BMI ( P =0.069), higher prevalence of diabetic peripheral neuropathy (DPN), and higher prevalence of diabetic retinopathy (DR) than the patients with mild-moderate OSAS. Similar levels of macrovascular complications were found in the three groups ( P >0.05). The logistic regression analyses showed that DPN ( OR =1.024, 95% CI 1.002-1.046) and chronic kidney disease ( OR =1.026, 95% CI 1.004-1.049) were independent predictors of AHI, adjusting for the lowest oxygen saturation, gender, age, diabetic duration, family history of diabetes, BMI, and HbA1c. Other microvascular and macrovascular complications were not predictors of AHI. Patients with T2DM and severe OSAS have a higher risk of DPN and DR. Particular attention should be paid to T2DM patients with severe OSAS to prevent complications.

    Risk factors for incident type 2 diabetes, in particular, hepatic markers, have rarely been studied in leaner individuals. We aimed to identify the metabolic and hepatic markers associated with incident diabetes in men and women with a BMI of or=27 kg/m(2). Risk factors for 9 year incident diabetes were compared in the French Data from an Epidemiological Study on the Insulin Resistance Syndrome (DESIR) cohort. Comparisons were made between the 2,947 participants with a BMI of or=27 kg/m(2). There were 92 incident cases of diabetes in individuals with a BMI of or=27 kg/m(2). Among those who were not markedly overweight, classical biological markers were associated with 9 year incident diabetes, glycaemia being the strongest predictor. gamma-Glutamyltransferase (GGT), either considered as a continuous variable or at levels >or=20 U/l, was associated with incident diabetes, with a stronger effect in the BMI or=27 kg/m(2) (results after adjustment for alcohol intake, alanine aminotransferase, waist circumference and the HOMA insulin resistance index). In individuals with a BMI of resistance, suggesting potential interactions between GGT, enhanced hepatic neoglucogenesis and/or early alterations of insulin secretion.

    The oral-facial-digital syndrome type 1 (OFD1) includes limb, facial, intraoral malformations and the gene for the disorder was recently mapped to Xp22.3-p22.2. We report on monozygotic twin girls discordant for OFD1. Monozygosity is supported by placental pathology (monochorionic diamniotic) and molecular studies with probability of dizygosity twin has oral cavity abnormalities including median cleft lip, cleft palate, lobulated hamartomatous tongue, aberrant hyperplastic oral frenula, alveolar notches, and absent lateral incisors. Facial manifestations include telecanthus, hypoplastic alae nasi, and transient neonatal facial milia. The patient also has short and deviated fingers with partial cutaneous syndactyly. At 10 years, she has not had central nervous system or kidney problems. X-inactivation study revealed similar X-inactivation patterns in the lymphoblasts of both twins. We conclude that skewed X-inactivation is an unlikely cause for the discordance, which is more likely due to a postzygotic mutation in the affected twin. Copyright 1999 Wiley-Liss, Inc.

    Mutations in the human DNA methyltransferase 3B (DNMT3B) gene lead to ICF (immunodeficiency, centromeric region instability, and facial anomalies) syndrome type I. We have previously described a telomere-related phenotype in cells from these patients, involving severe hypomethylation of subtelomeric regions, abnormally short telomeres and high levels of telomeric-repeat-containing RNA (TERRA). Here we demonstrate that ICF-patient fibroblasts carry abnormally short telomeres at a low population doubling (PD) and enter senescence prematurely. Accordingly, we attempted to rescue the senescence phenotype by ectopic expression of human telomerase, which led to elongated telomeres with hypomethylated subtelomeres. The senescence phenotype was overcome under these conditions, thus dissociating subtelomeric-DNA hypomethylation per se from the senescence phenotype. In addition, we examined whether the subtelomeric methylation could be restored by expression of a normal copy of full length DNMT3B1 in ICF fibroblasts. Ectopic expression of DNMT3B1 failed to rescue the abnormal hypomethylation at subtelomeres. However, partial rescue of subtelomeric-hypomethylation was achieved by co-expression of DNMT3B1 together with DNA methyltransferase 3-like (DNMT3L), encoding a protein that functions as a stimulator of DNMT3A and DNMT3B. DNMT3B1 and DNMT3L are predominantly expressed during early embryonic development, suggesting that de novo subtelomeric DNA methylation during crucial stages of human embryonic development may be necessary for setting and maintaining normal telomere length.

    Full Text Available Autoimmune polyendocrine syndrome type 1 (APS-1 is a rare autosomal recessive disease defined by the presence of two of the three conditions: mucocutaneous candidiasis, hypoparathyroidism, and Addison's disease. Loss-of-function mutations of the autoimmune regulator (AIRE gene have been linked to APS-1. Here we report mutational analysis and functional characterization of an AIRE mutation in a consanguineous Chinese family with APS-1. All exons of the AIRE gene and adjacent exon-intron sequences were amplified by PCR and subsequently sequenced. We identified a homozygous missense AIRE mutation c.463G>A (p.Gly155Ser in two siblings with different clinical features of APS-1. In silico splice-site prediction and minigene analysis were carried out to study the potential pathological consequence. Minigene splicing analysis and subsequent cDNA sequencing revealed that the AIRE mutation potentially compromised the recognition of the splice donor of intron 3, causing alternative pre-mRNA splicing by intron 3 retention. Furthermore, the aberrant AIRE transcript was identified in a heterozygous carrier of the c.463G>A mutation. The aberrant intron 3-retaining transcript generated a truncated protein (p.G155fsX203 containing the first 154 AIRE amino acids and followed by 48 aberrant amino acids. Therefore, our study represents the first functional characterization of the alternatively spliced AIRE mutation that may explain the pathogenetic role in APS-1.

    The aim was to explore ophthalmic health care in female patients with Usher Syndrome type I (USH I) over 20 years and to evaluate the relationship between the ophthalmic health care and the health state of the patients from a health perspective. A retrospective study of records from ophthalmology departments (OD) and low vision clinics (LVC) from 1985 to 2004. Assessment of the reports was performed based on the International Classification of Functioning, Disability and Health (ICF). Findings were analysed by manifest content analysis with ICF as a framework and using four themes: health care system, procedure examinations, patient's functioning and disability and procedure actions. The records of nine female patients (aged 25-39 years, 1985) with USH I were selected from the national database of USH. A great number of notes were collected (OD 344 and LVC 566). Procedure examinations were exclusively oriented towards body structure and function. All patients showed aggravated visual impairment over and above the hearing and vestibular impairment. Procedure actions were oriented towards environmental factors. No correlation was found between procedures performed and patient's experience of disability. The high degree of resource allocation was not correlated to the patients' impairment. The study indicates that the ophthalmic health care was characterised by inefficiency. This conclusion is very serious because patients very likely face severe disability and emotional difficulties. ICF is ought to be incorporated in ophthalmic health care strategy to improve the health care.

  1. Screening of MITF and SOX10 regulatory regions in Waardenburg syndrome type 2.

    Directory of Open Access Journals (Sweden)

    Viviane Baral

    Full Text Available Waardenburg syndrome (WS is a rare auditory-pigmentary disorder that exhibits varying combinations of sensorineural hearing loss and pigmentation defects. Four subtypes are clinically defined based on the presence or absence of additional symptoms. WS type 2 (WS2 can result from mutations within the MITF or SOX10 genes; however, 70% of WS2 cases remain unexplained at the molecular level, suggesting that other genes might be involved and/or that mutations within the known genes escaped previous screenings. The recent identification of a deletion encompassing three of the SOX10 regulatory elements in a patient presenting with another WS subtype, WS4, defined by its association with Hirschsprung disease, led us to search for deletions and point mutations within the MITF and SOX10 regulatory elements in 28 yet unexplained WS2 cases. Two nucleotide variations were identified: one in close proximity to the MITF distal enhancer (MDE and one within the U1 SOX10 enhancer. Functional analyses argued against a pathogenic effect of these variations, suggesting that mutations within regulatory elements of WS genes are not a major cause of this neurocristopathy.

    Full Text Available Waardenburg Syndrome (WS is an autosomal-dominant disorder characterized by sensorineural hearing loss and pigmentary abnormalities of the eyes, hair, and skin. Microphthalmia-associated transcription factor (MITF gene mutations account for about 15% of WS type II (WS2 cases. To date, fewer than 40 different MITF gene mutations have been identified in human WS2 patients, and few of these were of Chinese descent. In this study, we report clinical findings and mutation identification in the MITF gene of 20 Chinese WS2 patients from 14 families. A high level of clinical variability was identified. Sensorineural hearing loss (17/20, 85.0% and heterochromia iridum (20/20, 100.0% were the most commonly observed clinical features in Chinese WS2 patients. Five affected individuals (5/20, 25.0% had numerous brown freckles on the face, trunk, and limb extremities. Mutation screening of the MITF gene identified five mutations: c.20A>G, c.332C>T, c.647_649delGAA, c.649A>G, and c.763C>T. The total mutational frequency of the MITF gene was 21.4% (3/14, which is significantly higher than the 15.0% observed in the fair-skinned WS2 population. Our results indicate that MITF mutations are relatively common among Chinese WS2 patients.

    Objective: To analyze the mutations of PAX3 gene in two Waardenburg syndrome type Ⅰ (WS1) pedigrees and make prenatal diagnosis for the high-risk 18-week-old fetus. Methods: PAX3 gene was first analyzed by Sanger sequencing and multiplex ligation-dependent probe amplification(MLPA) for detecting pathogenic mutation of the probands of the two pedigrees. The mutations were confirmed by MLPA and Sanger in parents and unrelated healthy individuals.Prenatal genetic diagnosis for the high-risk fetus was performed by amniotic fluid cell after genotyping. Results: A heterozygous PAX3 gene gross deletion (E7 deletion) was identified in all patients from WS1-01 family, and not found in 20 healthy individuals.Prenatal diagnosis in WS1-01 family indicated that the fetus was normal. Molecular studies identified a novel deletion mutation c. 1385_1386delCT within the PAX3 gene in all affected WS1-02 family members, but in none of the unaffected relatives and 200 healthy individuals. Conclusions: PAX3 gene mutation is etiological for two WS1 families. Sanger sequencing plus MLPA is effective and accurate for making gene diagnosis and prenatal diagnosis.

  6. Is reflex sympathetic dystrophy/complex regional pain syndrome type I a small-fiber neuropathy?

    Science.gov (United States)

    Oaklander, Anne Louise; Fields, Howard L

    2009-06-01

    Neurologist S. Weir Mitchell first described "causalgia" following wartime nerve injury, with its persistent distal limb burning pain, swelling, and abnormal skin color, temperature, and sweating. Similar post-traumatic symptoms were later identified in patients without overt nerve injuries after trauma. This was labeled reflex sympathetic dystrophy (RSD; now complex regional pain syndrome type I [CRPS-I]). The pathophysiology of symptoms is unknown and treatment options are limited. We propose that persistent RSD/CRPS-I is a post-traumatic neuralgia associated with distal degeneration of small-diameter peripheral axons. Small-fiber lesions are easily missed on examination and are undetected by standard electrophysiological testing. Most CRPS features-spreading pain and skin hypersensitivity, vasomotor instability, osteopenia, edema, and abnormal sweating-are explicable by small-fiber dysfunction. Small fibers sense pain and temperature but also regulate tissue function through neuroeffector actions. Indeed, small-fiber-predominant polyneuropathies cause CRPS-like abnormalities, and pathological studies of nerves from chronic CRPS-I patients confirm small-fiber-predominant pathology. Small distal nerve injuries in rodents reproduce many CRPS features, further supporting this hypothesis. CRPS symptoms likely reflect combined effects of axonal degeneration and plasticity, inappropriate firing and neurosecretion by residual axons, and denervation supersensitivity. The resulting tissue edema, hypoxia, and secondary central nervous system changes can exacerbate symptoms and perpetuate pathology. Restoring the interest of neurologists in RSD/CRPS should improve patient care and broaden our knowledge of small-fiber functions.

    Full Text Available Background. This study examines gestational diabetes mellitus (GDM in women with polycystic ovary syndrome (PCOS and the risk of type 2 diabetes mellitus (DM following GDM pregnancy. Methods. A cohort of 988 pregnant women with PCOS who delivered during 2002–2005 was examined to determine the prevalence and predictors of GDM, with follow-up through 2010 among those with GDM to estimate the risk of DM. Results. Of the 988 pregnant women with PCOS, 192 (19% developed GDM. Multivariable predictors of GDM included older age, Asian race, prepregnancy obesity, family history of DM, preconception metformin use, and multiple gestation. Among women with PCOS and GDM pregnancy, the incidence of DM was 2.8 (95% confidence interval (CI 1.9–4.2 per 100 person-years and substantially higher for those who received pharmacologic treatment for GDM (6.6 versus 1.5 per 100 person-years, p<0.01. The multivariable adjusted risk of DM was fourfold higher in women who received pharmacologic treatment for GDM (adjusted hazard ratio 4.1, 95% CI 1.8–9.6. The five-year incidence of DM was 13.1% overall and also higher in the pharmacologic treatment subgroup (27.0% versus 7.1%, p<0.01. Conclusions. The strongest predictors of GDM among women with PCOS included Asian race and prepregnancy obesity. Pharmacologic treatment of GDM is associated with fourfold higher risk of subsequent DM.

    The Ehlers-Danlos syndrome, hypermobility type (EDS-HT) is a rare genetic disease. Diagnosis is based on a combination of clinical criteria described in the classification of Villefranche. Diagnosis is difficult to make because of the lack of specific clinical signs and the absence of genetic testing. The EDS-TH manifests itself manly by musculoskeletal pain and joint hypermobility. Temporomandibular disorders (TMD) are also reported. Our aim was to objectify the presence and to qualify the type of TMD associated with the EDS-HT in order to propose an additional diagnostic argument. A prospective, monocenter case-control study, comparing a cohort of patients suffering from EDS-HT to a paired control group of healthy volunteers has been conducted. Clinical examination was standardized, including a general questioning, an oral examination and a temporomandibular joint examination following the TMD/RDC (temporomandibular disorders/research diagnostic criteria). Fourteen EDS-HT patients and 58 control patients were examined. The prevalence of TMDs (n=13; 92.9% vs. n=4; 6.9%; P=10(-11)) was significantly higher in the EDS-HT group. TMDs occurring in the EDS-HT group were complex, combining several mechanisms in contrast to the control group, where only one mechanism was found in all the patients (n=13; 92.9% vs. n=0; 0.0%). TMDs are strongly associated with RDS-HT. TMDs could therefore be used in the diagnosis of this disease. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

It is an autosomal dominant inherited disorder caused by type III procollagen gene (COL3A1: MIM #120180 mutations. Approximately 50% of the COL3A1 mutations are inherited from an affected parent, and 50% are de novo mutations. Each child of an affected individual has a 50% chance of inheriting the mutation and developing the disorder. Pregnant women with vascular EDS are at an increased risk of uterine and arterial rupture during the peripartum period, with high maternal morbidity and mortality rates. We report the first case of an asymptomatic 35-year-old woman at a risk of complications of vascular EDS who underwent presymptomatic evaluation during pregnancy. The sequencing results of both her brother and mother had a one-base-pair deletion, resulting in Glutamate at position 730 changing to Lysine and causing a frame shift and premature termination codon at 61 amino acids from the mutation position (p. Glu730Lysfs*61 on exon 32 of COL3A1. This deletion caused frameshift, leading to a premature termination codon (TAG at 181 nucleotides downstream in exon 35, which could not be detected by previous total RNA (ribonucleic acid method. Thus, she was at risk of complications of vascular EDS, and diagnostic testing was employed

    Psychological distress is a known feature of generalized joint hypermobility (gJHM), as well as of its most common syndromic presentation, namely Ehlers-Danlos syndrome, hypermobility type (a.k.a. joint hypermobility syndrome - JHS/EDS-HT), and significantly contributes to the quality of life of affected individuals. Most published articles dealt with the link between gJHM (or JHS/EDS-HT) and anxiety-related conditions, and a novel generation of studies is emerging aimed at investigating the psychopathologic background of such an association. In this paper, literature review was carried out with a semi-systematic approach spanning the entire spectrum of psychopathological findings in gJHM and JHS/EDS-HT. Interestingly, in addition to the confirmation of a tight link between anxiety and gJHM, preliminary connections with depression, attention deficit (and hyperactivity) disorder, autism spectrum disorders, and obsessive-compulsive personality disorder were also found. Few papers investigated the relationship with schizophrenia with contrasting results. The mind-body connections hypothesized on the basis of available data were discussed with focus on somatotype, presumed psychopathology, and involvement of the extracellular matrix in the central nervous system. The hypothesis of positive Beighton score and alteration of interoceptive/proprioceptive/body awareness as possible endophenotypes in families with symptomatic gJHM or JHS/EDS-HT is also suggested. Concluding remarks addressed the implications of the psychopathological features of gJHM and JHS/EDS-HT in clinical practice. © 2015 Wiley Periodicals, Inc.

    Ehlers-Danlos Syndrome, hypermobility type (EDS-HT) and the joint hypermobility syndrome (JHS) are connective tissue disorders that form an overlapping clinical syndrome and are associated with frequent medical visits and substantial morbidity. EDS-HT/JHS-associated pain correlates with poor quality of life. While physical therapy is the recommended treatment for EDS-HT/JHS, little is known about therapy-related patient experiences and iatrogenic injuries. We studied 38 adult EDS-HT/JHS patients, eliciting health-related quality of life (HRQoL) from 28 patients through the RAND SF-36 questionnaire. We also explored physical therapy experiences through focus groups with 13 patients. Our patients displayed poor HRQoL, with 71% reporting worse health over the past year. SF-36 scores were significantly lower than the scores of the average American population (P < 0.001 for 8 of 10 categories assessed), but were comparable to EDS-HT/JHS populations in Belgium, the Netherlands, Sweden, and Italy. Focus groups identified factors associated with: negative past physical therapy experiences, iatrogenic joint injuries, positive treatment experiences, and unmet rehabilitation needs. This group of EDS-HT/JHS patients has significant decrements in HRQoL and many unmet treatment needs, as well as a risk for iatrogenic injuries. We identify several approaches to help meet patients' needs and improve joint rehabilitation in patients with EDS-HT/JHS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Metabolic syndrome is a cluster of the most dangerous heart attack risk factors such as diabetes and prediabetes, abdominal obesity, high cholesterol and high blood pressure. Hyperuricemia is a condition in which the serum uric acid concentration is greater than 5.5 mg per deciliter for child and greater than 7.2 and 6.0 mg per deciliters for male and female adults respectively. A cross-sectional study was conducted to determine the magnitude of hyperuricemia and associated factors among type 2 diabetes mellitus patients at Hawassa Comprehensive Specialized Hospital (HCSH) from February 28 to May 30 /2017. A random sampling technique was used to include 319 study subjects and a signed consent had been provided by each study subject before running any data collection. An interviewer administered structured questionnaire was used to collect socio-demographic and some clinically useful data. In addition to this, we reviewed the records of the study subjects to obtain other useful clinical data. Five milliliter blood specimen was collected from each study subjects after overnight fasting. A25TM Bio-System Random Access chemistry analyzer was used for blood sample analysis. All data were checked visually, coded and entered into epi-data version 3.4 and statistical analysis was performed using SPSS version 20.0 software. Bi-variate and multivariate logistic regressions were used to determine the association between explanatory and the outcome variables. The prevalence of hyperuricemia and metabolic syndrome among type 2 diabetic patients in the study area were 33.8%(n = 106) and 70.1% (n = 220) respectively. Having age greater or equal to 45 years (AOR: 1.9, CI: 1.-3.2, P value =0.015) and having metabolic syndrome (AOR: 2.6, CI: 1.5-4.7, P value = 0.001) were the determinant variables for hyperuricemia among type 2 diabetic patients. There was high prevalence of hyperuricemia among type 2 diabetic patients with high prevalence of metabolic syndrome

    Chronic widespread musculoskeletal pain is a cardinal symptom in hypermobility type of Ehler Danlos Syndrome (EDS type III). The management of pain in EDS, however, has not been studied in depth. A 30 year old female, known case of EDS, presented to the pain clinic with complaints of severe upper back pain for 6 months. Physical examination of the back revealed two myofascial trigger points over the left rhomboids and the left erector spinae. Local anaesthetic trigger point injections were given at these points, followed by stretching exercises under analgesic cover for the first week. After 1 week the patient reported 60-80% pain relief. This case highlights that we must keep a high index of suspicion for the more treatable causes of pain like myofascial pain syndrome in patients suffering from EDS, and should address it promptly and appropriately in order to maximise patient comfort.

    This paper gives experimental proof of an intriguing physical effect: periodic on-off switching of MOS transistors in a CMOS ring oscillator reduces their intrinsic 1/f noise and hence the oscillator's close-in phase noise. More specifically, it is shown that the 1/f3 phase noise is dependent on the

    To identify the interaction between influenza A virus PB1-F2 and human modulator of apoptosis 1 (MOAP-1). The recombinant plasmid pACT2-MOAP-1 was constructed and co-transformed into yeast AH109 with pGBKT7-PB1-F2. The growth of the co-transformants on quadruple dropout medium and beta-galactosidase activity of the reporter gene were tested. We further confirmed the interaction of cellular protein MOAP-1 and PB1-F2 by glutathione S-transferase (GST) pull-down and co-immunoprecipitation (Co-IP) assays. In addition, we investigated the effect of PB1-F2 on MOAP-1 protein level by Western blot. The results of yeast two-hybrid assay showed that MOAP-1 specifically interacted with PB1-F2 in yeast cells. Furthermore, the binding of MOAP-1 with PB1-F2 was demonstrated by glutathione S-transferase pull-down and Co-IP assays. PB1-F2 could upregulate exogenous MOAP-1 protein level. These results suggested that influenza virus PB1-F2 interacted with MOAP-1 and it might be involved in the regulation of cell growth and apoptosis via association with MOAP-1.

    In this paper we report the results of extensive research on phase modulation (PM) and amplitude modulation (AM) noise in linear bipolar junction transistor (BJT) amplifiers. BJT amplifiers exhibit 1/f PM and AM noise about a carrier signal that is much larger than the amplifiers thermal noise at those frequencies in the absence of the carrier signal. Our work shows that the 1/f PM noise of a BJT based amplifier is accompanied by 1/f AM noise which can be higher, lower, or nearly equal, depending on the circuit implementation. The 1/f AM and PM noise in BJTs is primarily the result of 1/f fluctuations in transistor current, transistor capacitance, circuit supply voltages, circuit impedances, and circuit configuration. We discuss the theory and present experimental data in reference to common emitter amplifiers, but the analysis can be applied to other configurations as well. This study provides the functional dependence of 1/f AM and PM noise on transistor parameters, circuit parameters, and signal frequency, thereby laying the groundwork for a comprehensive theory of 1/f AM and PM noise in BJT amplifiers. We show that in many cases the 1/f PM and AM noise can be reduced below the thermal noise of the amplifier.

    Full Text Available Recurrent Aphthous Stomatitis (RAS is a common inflammatory condition of the oral mucosa. The aetiology of RAS remains unclear, yet there are several predisposing factors which could be involved in the onset of the lesion. The herpetiform type of RAS appeared to be similar to recurrent oral Herpes Simplex infection and also could be part of Behçet Syndrome. This case report discussed a patient suffering from a herpetiform type of RAS with its clinical appearance resembling recurrent oral Herpes Simplex infection and Behçet syndrome. Initial treatment was undertaken based on the empirical treatment, yet the respond was not satisfactory. Then, laboratory tests were undertaken, including complete blood count, the total population of T lymphocyte, B lymphocyte, T helper, T suppressor, NK cells, T helper/T suppressor ratio, C3, C4, IgG, IgA, and IgM. These tests showed that there were immune and hematinic deficiency condition. Nevertheless, the clinical appearance, laboratory findings and consultation did not support the diagnosis of recurrent oral Herpes Simplex infection and Behçet Syndrome, thus, enhancing the definite diagnosis of the herpetiform type of RAS with immune and hematinic deficiency as the underlying condition. Based on the definite diagnosis, treatment plan was then revised to target the underlying condition.

We used the ATP III criteria and the IDF criteria for the diagnosis of MetS and sorted the subjects into 2 MetS groups: one group diagnosed per ATP III criteria (MetSa and one diagnosed per IDF criteria (MetSi. We then compared the clinical characteristics, metabolic parameters (homeostasis model assessment of insulin resistance, aspartate aminotransferase, alanine aminotransferase, and uric acid values and co-morbidities (prevalence of microalbuminuria, fatty liver, and cardiovascular disease between the MetSa, MetSi, and discordant MetS groups.ResultsThe prevalence of MetS in the MetSa group (73.6% was higher than in the MetSi group (62.2%. The MetS prevalence in the discordant group was 11.4%. The discordant group showed no significant differences in clinical characteristics (except waist circumference and body mass index, metabolic parameters, or prevalence of co-morbidities, as compared with subjects with MetS by both criteria.ConclusionIn this study, cardio-metabolic features of the subjects diagnosed with MetS using ATP III criteria, but not IDF criteria, are not significantly different from those of subjects diagnosed with MetS using both criteria.

    Full Text Available Objective: To investigate working memory, phonological skills, lexical skills, and reading comprehension in adults with Usher syndrome type 2 (USH2.Design: The participants performed tests of phonological processing, lexical access, working memory and reading comprehension. The design of the test situation and tests was specifically considered for use with persons with low vision in combination with hearing impairment. The performance of the group with USH2 on the different cognitive measures was compared to that of a matched control group with normal hearing and vision (NVH.Study Sample: Thirteen participants with USH2 aged 21–60 years and a control group of ten individuals with NVH, matched on age and level of education.Results: The group with USH2 displayed significantly lower performance on tests of phonological processing, and on measures requiring both fast visual judgment and phonological processing. There was a larger variation in performance among the individuals with USH2 than in the matched control group.Conclusions: The performance of the group with USH2 indicated similar problems with phonological processing skills and phonological working memory as in individuals with long-term hearing loss. The group with USH2 also had significantly longer reaction times, indicating that processing of visual stimuli is difficult due to the visual impairment. These findings point toward the difficulties in accessing information that persons with USH2 experience, and could be part of the explanation of why individuals with USH2 report high levels of fatigue and feelings of stress (Wahlqvist et al., 2013.

    Full Text Available The complex regional pain syndrome (CRPS is a rare but debilitating pain disorder that mostly occurs after injuries to the upper limb. A number of studies indicated altered brain function in CRPS, whereas possible influences on brain structure remain poorly investigated. We acquired structural magnetic resonance imaging data from CRPS type I patients and applied voxel-by-voxel statistics to compare white and gray matter brain segments of CRPS patients with matched controls. Patients and controls were statistically compared in two different ways: First, we applied a 2-sample ttest to compare whole brain white and gray matter structure between patients and controls. Second, we aimed to assess structural alterations specifically of the primary somatosensory (S1 and motor cortex (M1 contralateral to the CRPS affected side. To this end, MRI scans of patients with left-sided CRPS (and matched controls were horizontally flipped before preprocessing and region-of-interest-based group comparison. The unpaired ttest of the "non-flipped" data revealed that CRPS patients presented increased gray matter density in the dorsomedial prefrontal cortex. The same test applied to the "flipped" data showed further increases in gray matter density, not in the S1, but in the M1 contralateral to the CRPS-affected limb which were inversely related to decreased white matter density of the internal capsule within the ipsilateral brain hemisphere. The gray-white matter interaction between motor cortex and internal capsule suggests compensatory mechanisms within the central motor system possibly due to motor dysfunction. Altered gray matter structure in dorsomedial prefrontal cortex may occur in response to emotional processes such as pain-related suffering or elevated analgesic top-down control.

    Full Text Available Abstract Background Hermansky-Pudlak syndrome (HPS is a disorder of lysosome-related organelle biogenesis characterized by oculocutaneous albinism and prolonged bleeding. These clinical findings reflect defects in the formation of melanosomes in melanocytes and dense bodies in platelets. HPS type-3 (HPS-3 results from mutations in the HPS3 gene, which encodes a 1004 amino acid protein of unknown function that contains a predicted clathrin-binding motif (LLDFE at residues 172–176. Results Clathrin was co-immunoprecipitated by HPS3 antibodies from normal but not HPS3 null melanocytes. Normal melanocytes expressing a GFP-HPS3 fusion protein demonstrated partial co-localization of GFP-HPS3 with clathrin following a 20°C temperature block. GFP-HPS3 in which the predicted clathrin-binding domain of HPS3 was mutated (GFP-HPS3-delCBD did not co-localize with clathrin under the same conditions. Immunoelectron microscopy of normal melanocytes expressing GFP-HPS3 showed co-localization of GFP-HPS3 with clathrin, predominantly on small vesicles in the perinuclear region. In contrast, GFP-HPS3-delCBD did not co-localize with clathrin and exhibited a largely cytoplasmic distribution. Conclusion HPS3 associates with clathrin, predominantly on small clathrin-containing vesicles in the perinuclear region. This association most likely occurs directly via a functional clathrin-binding domain in HPS3. These results suggest a role for HPS3 and its protein complex, BLOC-2, in vesicle formation and trafficking.

    Usher syndrome type 1b (USH1B) is an autosomal recessive disorder characterized by congenital profound hearing loss, vestibular abnormalities, and retinitis pigmentosa. The disorder has recently been shown to be caused by mutations in the myosin VIIa gene (MYO7A) located on 11q14. In the current study, a panel of 189 genetically independent Usher I cases were screened for the presence of mutations in the N-terminal coding portion of the motor domain of MYO7A by heteroduplex analysis of 14 exons. Twenty-three mutations were found segregating with the disease in 20 families. Of the 23 mutations, 13 were unique, and 2 of the 13 unique mutations (Arg212His and Arg212Cys) accounted for the greatest percentage of observed mutant alleles (8/23, 31%). Six of the 13 mutations caused premature stop codons, 6 caused changes in the amino acid sequence of the myosin VIIa protein, and 1 resulted in a splicing defect. Three patients were homozygotes or compound heterozygotes for mutant alleles; these three cases were Tyr333Stop/Tyr333Stop, Arg212His-Arg302His/Arg212His-Arg302His, and IVS13nt-8c{r_arrow}g/ G1u450Gln. All the other USH1B mutations observed were simple heterozygotes, and it is presumed that the mutation on the other allele is present in the unscreened regions of the gene. None of the mutations reported here were observed in 96 unrelated control samples, although several polymorphisms were detected. These results add three patients to a single case reported previously where mutations have been found in both alleles and raises the total number of unique mutations in MYO7A to 16. 22 refs., 4 figs., 3 tabs.

    To examine the prevalence of a history of polycystic ovary syndrome (PCOS) in women with type 2 diabetes (DM2) and to compare metabolic and reproductive outcomes between women with and without PCOS. Cross-sectional study. Tertiary hospital. Female inpatients age 18-75 years with DM2. A face-to-face questionnaire was administered. Age at diagnosis of diabetes, history of gestational diabetes, family history of diabetes, and reproductive history, fertility history, number of miscarriages, and morbidity in pregnancy. One hundred seventy-one inpatients with DM2 participated. The prevalence of a history of PCOS was 37%. Women with PCOS had an earlier mean age of diagnosis of DM2 (44.2 vs. 48.8 years), higher recalled peak body mass index (BMI; 43.1 kg/m 2 vs. 36.8 kg/m 2 ), higher rate of gestational diabetes (28% vs. 18%), and higher rate of hypertension in pregnancy (40% vs. 22%). Women with PCOS were less likely to have a family history of DM2 than those without PCOS (45% vs. 67%). A history of PCOS in women with DM2 is associated with earlier onset of DM2, higher BMI, and a more severe phenotype. Since PCOS subjects were less likely to have a family history of DM2, lack of a family history of DM2 in women with PCOS is not reassuring for DM2 risk. We recommend identifying PCOS in early life and intervening to reduce the risk of diabetes and its comorbidities and suboptimal reproductive outcomes. Crown Copyright © 2016.

    Full Text Available Abstract Background The prevalence of gastroesophageal reflux disease (GERD has been increasing worldwide. Abdominal obesity or visceral fat accumulation rather than simple obesity is associated with GERD. Previous reports demonstrated the association between GERD and type 2 diabetes mellitus (T2DM. Signification of visceral fat accumulation and adiponectin in T2DM patients with GERD remains unclear. The present study investigated the relationships between GERD symptoms, visceral fat accumulation and adiponectin in subjects with T2DM. Findings The study (ADMIT study subjects were 66 Japanese T2DM outpatients, who answered the questionnaire regarding GERD symptoms in Frequency Scale for the Symptoms of GERD (FSSG, and were measured visceral fat area by bioelectrical impedance analysis. Patients with FSSG scores of more than 8 were considered as positive. The prevalence of FSSG score ≥ 8 and average FSSG score in T2DM subjects with the metabolic syndrome (Mets were significantly higher compared to those without Mets. The prevalence of FSSG score ≥ 8 and average FSSG score in T2DM subjects with low levels of serum adiponectin were significantly higher compared to those with high levels of serum adiponectin. Moreover, the combination of Mets and hypoadiponectinemia had a multiplicative effect on GERD symptom score (p = 0.047. Conclusions Our study showed that the coexistence of MetS and low levels of serum adiponectin was associated with the higher prevalence of FSSG score ≥ 8 and the higher scores of GERD symptom in subjects with T2DM.

    Purpose To detect paired box gene 3 (PAX3) mutations and associated phenotypes in Chinese patients with Waardenburg syndrome type 1 (WS1). Methods Five unrelated families with suspected WS1 were selected from our Genomic DNA Repository for Hereditary Eye Diseases. The coding and adjacent intronic regions of PAX3 were amplified by polymerase chain reaction and the amplicons were then analyzed by cycle sequencing. Variations detected were further evaluated in available family members as well as one hundred controls with heteroduplex-single strand conformational polymorphism (heteroduplex-SSCP) analysis and/or clone sequencing. Results Three novel and two known mutations in PAX3 were detected in five patients, respectively: c.567_586+17del (p.Asp189_Gln505delinsGluGlyGlyAlaLeuAlaGly), c.456_459dupTTCC (p.Ile154PhefsX162), c.795_800delCTGGTT (p.Trp266_Phe267del), c.799T>A (p.Phe267Ile), and c.667C>T (p.Arg223X). Two novel mutations proved to be de novo as their parents did not carry the mutations. All five patients with PAX3 mutations had dystopia canthorum and different iris color and fundi between their two eyes. However, none had white forelock, skin hypopigmentation, and deafness. Conclusions Our findings expand the frequency and spectrum of PAX3 mutations and ethnic-related phenotypes in Chinese patients with WS1. De novo mutations in PAX3 have not been reported before.

    Waardenburg syndrome (WS) is an auditory-pigmentary disorder with varying combinations of sensorineural hearing loss and abnormal pigmentation. The present study aimed to investigate the underlying molecular pathology and provide a method of prenatal diagnosis of WS in Chinese families. A total of 11 patients with WS from five unrelated Chinese families were enrolled. A thorough clinical examination was performed on all participants. Furthermore, patients with WS underwent screening for mutations in the following genes: Paired box 3 (PAX3), melanogenesis associated transcription factor (MITF), SRY-box 10, snail family transcriptional repressor 2 and endothelin receptor type B using polymerase chain reaction sequencing. Array-based comparative genomic hybridization was used for specific patients whose sequence results were normal. Following identification of the genotype of the probands and their parents, prenatal genetic diagnosis was performed for family 01 and 05. According to the diagnostic criteria for WS, five cases were diagnosed as WS1, while the other six cases were WS2. Genetic analysis revealed three mutations, including a nonsense mutation PAX3 c.583C>T in family 01, a splice-site mutation MITF c.909G>A in family 03 and an in-frame deletion MITF c.649_651delGAA in family 05. To the best of the authors' knowledge the mutations (c.583C>T in PAX3 and c.909G>A in MITF) were reported for the first time in Chinese people. Mutations in the gene of interest were not identified in family 02 and 04. The prenatal genetic testing of the two fetuses was carried out and demonstrated that the two babies were normal. The results of the present study expanded the range of known genetic mutations in China. Identification of genetic mutations in these families provided an efficient way to understand the causes of WS and improved genetic counseling. PMID:29115496

    Full Text Available Objective: Autoimmune polyendocrine syndrome type 1 (APS1 is a rare autosomal recessive disorder characterized by progressive organ-specific autoimmunity. There is scant information on APS1 in ethnic groups other than European Caucasians. We studied clinical aspects and autoimmune regulator (AIRE gene mutations in a cohort of Indian APS1 patients. Design: Twenty-three patients (19 families from six referral centres in India, diagnosed between 1996 and 2016, were followed for [median (range] 4 (0.2–19 years. Methods: Clinical features, mortality, organ-specific autoantibodies and AIRE gene mutations were studied. Results: Patients varied widely in their age of presentation [3.5 (0.1–17 years] and number of clinical manifestations [5 (2–11]. Despite genetic heterogeneity, the frequencies of the major APS1 components (mucocutaneous candidiasis: 96%; hypoparathyroidism: 91%; primary adrenal insufficiency: 55% were similar to reports in European series. In contrast, primary hypothyroidism (23% occurred more frequently and at an early age, while kerato-conjunctivitis, urticarial rash and autoimmune hepatitis were uncommon (9% each. Six (26% patients died at a young age [5.8 (3–23 years] due to septicaemia, hepatic failure and adrenal/hypocalcaemic crisis from non-compliance/unexplained cause. Interferon-α and/or interleukin-22 antibodies were elevated in all 19 patients tested, including an asymptomatic infant. Eleven AIRE mutations were detected, the most common being p.C322fsX372 (haplotype frequency 37%. Four mutations were novel, while six others were previously described in European Caucasians. Conclusions: Indian APS1 patients exhibited considerable genetic heterogeneity and had highly variable clinical features. While the frequency of major manifestations was similar to that of European Caucasians, other features showed significant differences. A high mortality at a young age was observed.

    To compare the power of tests assessing different cognitive domains for the identification of prodromal Alzheimer disease (AD) among patients with mild cognitive impairment (MCI). Given the early involvement of the medial temporal lobe, a precocious and specific pattern of memory disorders might be expected for the identification of prodromal AD. A total of 251 patients with MCI were tested at baseline by a standardized neuropsychological battery, which included the Free and Cued Selective Recall Reminding Test (FCSRT) for verbal episodic memory; the Benton Visual Retention Test for visual memory; the Deno 100 and verbal fluency for language; a serial digit learning test and the double task of Baddeley for working memory; Wechsler Adult Intelligence Scale (WAIS) similarities for conceptual elaboration; and the Stroop test, the Trail Making test, and the WAIS digit symbol test for executive functions. The patients were followed at 6-month intervals for up to 3 years in order to identify those who converted to AD vs those who remained stable over time. Statistical analyses were based on receiver operating characteristic curve and Cox proportional hazards models. A total of 59 subjects converted to AD dementia. The most sensitive and specific test for diagnosis of prodromal AD was the FCSRT. Significant cutoff for the diagnosis was 17/48 for free recall, 40/48 for total recall, and below 71% for index of sensitivity of cueing (% of efficacy of semantic cues for retrieval). The amnestic syndrome of the medial temporal type, defined by the Free and Cued Selective Recall Reminding Test, is able to distinguish patients at an early stage of Alzheimer disease from mild cognitive impairment non-converters.

    Cockayne syndrome (CS) is an autosomal recessive disease associated with premature aging, progressive multiorgan degeneration, and nervous system abnormalities including cerebral and cerebellar atrophy, brain calcifications, and white matter abnormalities. Although several clinical descriptions of CS patients have reported developmental delay and cognitive impairment with relative preservation of social skills, no previous studies have carried out a comprehensive neuropsychological and social cognition assessment. Furthermore, no previous research in individuals with CS has examined the relationship between brain atrophy and performance on neuropsychological and social cognition tests. This study describes the case of an atypical late-onset type III CS patient who exceeds the mean life expectancy of individuals with this pathology. The patient and a group of healthy controls underwent a comprehensive assessment that included multiple neuropsychological and social cognition (emotion recognition, theory of mind, and empathy) tasks. In addition, we compared the pattern of atrophy in the patient to controls and to its concordance with ERCC8 gene expression in a healthy brain. The results showed memory, language, and executive deficits that contrast with the relative preservation of social cognition skills. The cognitive profile of the patient was consistent with his pattern of global cerebral and cerebellar loss of gray matter volume (frontal structures, bilateral cerebellum, basal ganglia, temporal lobe, and occipito-temporal/occipito-parietal regions), which in turn was anatomically consistent with the ERCC8 gene expression level in a healthy donor’s brain. The study of exceptional cases, such as the one described here, is fundamental to elucidating the processes that affect the brain in premature aging diseases, and such studies provide an important source of information for understanding the problems associated with normal and pathological aging.

    Hypermobility-type Ehlers-Danlos syndrome (EDS), an often-missed diagnosis with the potential for serious sequelae, may have a variety of uncommon presentations, some of which may be gynecologic. The aim of this case report is to present two cases of profound labial edema associated with intercourse as a presenting symptom of hypermobility-type EDS. A 25-year-old female presented with severe labia minora swelling and bladder pressure associated with intercourse, in addition to persistent genital arousal. History revealed easy bruising, joint pain, and family history of aneurysm. A 22-year-old female presented with intermittent profound labial swelling for 6 years, associated with sensitivity and pain with intercourse. The patient has a history of joint pain and easy bruising, as well a sister with joint hypermobility and unexplained lymphedema. The presenting symptom of profound labial edema led to the diagnosis of hypermobility-type EDS. Patients with hypermobility syndrome exhibit an increased ratio of type III collagen to type I collagen, causing tissue laxity and venous insufficiency. Abnormal collagen may lead to gynecologic manifestations, including unexplained profound labial edema, pelvic organ prolapse in the absence of risk factors, and possibly persistent genital arousal. This case report highlights the need for further research to determine incidence of labial edema in hypermobility-type EDS and to further elucidate a potential correlation between profound labial edema and collagen disorders. © 2013 International Society for Sexual Medicine.

  5. Complex regional pain syndrometype I: What’s in a name?

    2015-01-01

    Within a two year period in the 1940’s, two Boston physicians published dramatically opposing views on the underlying nature of a syndrome now known as complex regional pain syndrome (CRPS). Evans suggested, in several papers in 1946–1947, that sympathetic reflexes maintain pain and dystrophy in affected limbs. Foisie, in 1947, suggested arterial vasospasms were key in the etiology of this pain syndrome. Evans’ hypothesis established the nomenclature for this syndrome for 60 years, and his term “reflex sympathetic dystrophy” guided clinical treatment and research activities over the same period. Foisie’s proposed nomenclature was unrecognized, and had virtually no impact on the field. Recent evidence suggests that Evans’ contribution to the field may have in fact lead clinicians and researchers astray all those years. This focus article on CRPS compares recent observations with these 2 earlier theories and asks the question -- what if we had adopted Foisie’s nomenclature from the beginning? PMID:20634146

    Vaccine-like viruses of American type of porcine reproductive and respiratory syndrome virus (PRRSV) were detected in serum samples by RT-PCR. The viruses were analysed by nucleotide sequencing of the genomic region encoding open reading frames 2 to 7. During the ongoing study of Danish isolates...... of PRRSV by means of nucleotide sequencing, RT-PCR reactions and subsequent nucleotide sequencing showed the presence of American type PRRSV in Danish breeding herds. Most likely, these atypical viruses originated from boars vaccinated with live vaccine of American type (MLV RespPRRS), which were taken.......2-99.5% to the vaccine virus RespPRRS and 99.0-99.3% to VR2332 which are the parental virus to the vaccine virus. Phylogenetic analysis including field isolates of American type supports the conclusion chat the introduction of American type PRRSV in Denmark was due to spread of vaccine virus....

    Several fused bicyclic systems have been investigated to serve as the core structure of potent and selective 5-HT1F receptor agonists. Replacement of the indole nucleus in 2 with indazole and 'inverted' indazole provided more potent and selective 5-HT1F receptor ligands. Indoline and 1,2-benzisoxazole systems also provided potent 5-HT1F receptor agonists, and the 5-HT1A receptor selectivity of the indoline- and 1,2-benzisoxazole-based 5-HT1F receptor agonists could be improved with modification of the benzoyl moiety of the benzamides. Through these studies, we found that the inherent geometries of the templates, not the nature of hybridization of the linking atom, were important for the 5-HT1F receptor recognition.

  12. Chronic Inhibition of 11β-Hydroxysteroid Dehydrogenase Type 1 Activity Decreases Hypertension, Insulin Resistance, and Hypertriglyceridemia in Metabolic Syndrome

    Full Text Available Metabolic syndrome is a constellation of risk factors including hypertension, dyslipidemia, insulin resistance, and obesity that promote the development of cardiovascular disease. Metabolic syndrome has been associated with changes in the secretion or metabolism of glucocorticoids, which have important functions in adipose, liver, kidney, and vasculature. Tissue concentrations of the active glucocorticoid cortisol are controlled by the conversion of cortisone to cortisol by 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1. Because of the various cardiovascular and metabolic activities of glucocorticoids, we tested the hypothesis that 11β-HSD1 is a common mechanism in the hypertension, dyslipidemia, and insulin resistance in metabolic syndrome. In obese and lean SHR/NDmcr-cp (SHR-cp, cardiovascular, metabolic, and renal functions were measured before and during four weeks of administration of vehicle or compound 11 (10 mg/kg/d, a selective inhibitor of 11β-HSD1. Compound 11 significantly decreased 11β-HSD1 activity in adipose tissue and liver of SHR-cp. In obese SHR-cp, compound 11 significantly decreased mean arterial pressure, glucose intolerance, insulin resistance, hypertriglyceridemia, and plasma renin activity with no effect on heart rate, body weight gain, or microalbuminuria. These results suggest that 11β-HSD1 activity in liver and adipose tissue is a common mediator of hypertension, hypertriglyceridemia, glucose intolerance, and insulin resistance in metabolic syndrome.

    Microvascular complications of diabetes contribute significantly to the disease morbidity. The metabolic syndrome is common among subjects with diabetes and is a very important risk factor for macrovascular complications. However, its contribution to the microvascular complication has not been assessed. To assess the risk of microvascular complications associated with the metabolic syndrome in diabetes subjects. The study group comprised 415 diabetic subjects attending a primary care clinic. The prevalence of microvascular complications was compared between 270 diabetic subjects with metabolic syndrome (NCEP-III criteria) and 145 diabetic patients without. We found that as a group, diabetic subjects with metabolic syndrome had a significantly higher frequency of microvascular-related complications than diabetic subjects without the syndrome (46.6% and 26.8% respectively, P= 0.0005). These include microalbuminuria (41.5% vs. 23.9%, P= 0.013), neuropathy (10.4% vs. 7.5%, P = 0.38), retinopathy (9.6% vs. 4.1%, P = 0.046) and leg ulcers (7.9% vs. 2.8%, P = 0.044). After adjustment for age, gender, glycemic control, disease duration, lipid profile and blood pressure, metabolic syndrome was associated with a significantly higher risk of microvascular complications: odds ratio (95% confidence interval) for nephropathy 2.27 (1.53-3.34), neuropathy 1.77 (0.79-4.0), retinopathy 3.42 (1.2-9.87), and leg ulcers 3.57 (1.08-11.95). In addition to hyperglycemia and disease duration, the metabolic syndrome is a significant risk factor for the development of microvascular complications in diabetic subjects.

    To estimate the heritability, parental transmission and environmental contributions to the phenotypic variation in type 2 diabetes mellitus and metabolic syndrome-related traits in families of Mexican children and adolescents. We performed a cross-sectional study of 184 tri-generational pedigrees with a total of 1160 individuals (99 families with a type 2 diabetes mellitus proband before age 19). The family history of type 2 diabetes mellitus in three generations was obtained by interview. Demographic, anthropometric, biochemical and lifestyle information was corroborated in parents and offspring. We obtained correlations for metabolic traits between relative pairs, and variance component methods were used to determine the heritability and environmental components. The heritability of early-onset of type 2 diabetes mellitus was 0.50 (p2-h insulin, and cholesterol (p0.50) for blood pressure, HbA1c and HDL-cholesterol after multivariate adjustment (ptype 2 diabetes mellitus and insulin resistance, were significantly correlated only through the mother and others, such as hypertriglyceridemia, were significantly correlated only through the father. This study demonstrates that type 2 diabetes mellitus and metabolic syndrome-related traits are highly heritable among Mexican children and adolescents. Furthermore, several cardiometabolic factors have strong heritability and/or high environmental contributions that highlight the complex architecture of these alterations.

    Leigh syndrome, French-Canadian type is unique to patients from a genetic isolate in the Saguenay-Lac-Saint-Jean region of Québec. It has also been recently described in 10 patients with LRPPRC mutation outside of Québec. It is an autosomal recessive genetic disorder with fatal metabolic crisis and severe neurological morbidity in infancy caused by LRPPRC mutation. The authors report a boy with a novel LRPPRC compound heterozygous missense mutations c.3130C>T, c.3430C>T, and c.4078G>A found on whole-exome sequencing which correlated with isolated cytochrome c-oxidase deficiency found in skeletal muscle. LRPPRC mutation is a rare cause of cytochrome c-oxidase-deficient form of Leigh syndrome outside of Québec. Our patient broadens the spectrum of phenotypes of Leigh syndrome, French-Canadian type. LRPPRC mutation should be considered in children with early childhood neurodegenerative disorder, even in the absence of metabolic crisis. Early evaluation with whole-exome sequencing is useful for early diagnosis and for genetic counseling.

    These twenty last years, the metabolic syndrome was accused in various human pathologies including android obesity and type 2 diabetes. In obesity, increased body weight is frequently associated with excessive caloric food and sedentary activities. The Behaviour Eating Disorders (BED) is involved in over-consumption alimentary. In Algeria, we observed increasingly deviations in life-style alimentary, from the Mediterranean-Cretan model to American fast-food model. To study interactions between the BED, hormonal secretions and metabolic syndrome parameters. The present study was undertaken on Algerian population cohorts composed of 30 obese subjects, 70 type 2 diabetic patients and 30 healthy subjects. The BED was evaluated by TFEQ and DEBQ tests. Anthropometric parameters (waist circumference, IMC), metabolic parameters (glucose, triglycerides, HDL-C, LDL-C) and hormones (insulin, peptide C, ACTH, cortisol, GH) were determinates by biometrics, spectrophotometry and radioimmunology methods, respectively. Multivariate analyses showed the high correlation between the BED and the metabolic syndrome, particularly a critical insulinoresistance state (IR). This IR generates in periphery a whole of metabolic disorders: dyslipidemia, hyperglycemia and hypertrophy of adipose tissue. In diabetic and obese patients, cortisol, ACTH and GH secretions are insidiously altered and to lead metabolic disorders. In this study, the role of the BED in obesity and diabetes genesis seems to be confirmed. In response to nutritional stress, the BED generates a hyperactivity of endocrine pancreas, adrenal gland, and pituitary gland. It appeared that Algerian population is not adapted to fast-food American model.

    Sensorineural hearing impairment (HI) is one of the most frequent congenital defects, with a prevalence of 1 in 500 among neonates. Although there are over 400 syndromes involving HI, most cases of HI are nonsyndromic (70%), 20% of which follow autosomal dominant mode of inheritance. Waardenburg syndrome (WS) ranks first among autosomal dominant syndromic forms of HI. WS is characterized by sensorineural hearing impairment, pigmentation abnormalities of hair and skin and hypoplastic blue eyes or heterochromia iridis. WS is subdivided into four major types, WS1-WS4. WS1 is diagnosed by the presence of dystopia canthorum and PAX3 is the only gene involved. This study aims to determine the pathogenic mutation in a large Iranian pedigree affected with WS1 in order to further confirm the clinical diagnosis. In the present study, a family segregating HI was ascertained in a genetic counseling center. Upon clinical inspection, white forelock, dystopia canthorum, broad high nasal root and synophrys, characteristic of WS1 were evident. In order to clarify the genetic etiology and confirm the clinical data, primers were designed to amplify exons and exon-intron boundaries of the responsible gene, PAX3 with 10 exons, followed by the Sanger DNA sequencing method. Genetic analysis of PAX3 revealed a novel mutation in PAX3 (c.1024_1040 del AGCACGATTCCTTCCAA). Our data provide genotype-phenotype correlation for the mutation in PAX3 and WS1 in the studied family, with implications for genetic counseling, which necessitates detailed clinical inspection of HI patients to distinguish syndromic HI from the more common non-syndromic cases. Our results reveal the value of phenotype-directed genetic analysis and could further expand the spectrum of PAX3 mutations. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

  20. Internal carotid artery dissection in a patient with Ehlers-Danlos syndrome type IV: diagnosis and management

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Ehlers-Danlos syndrome (EDS type IV, also known as vascular EDS, is an inherited connective tissue disorder with an estimated prevalence of 1/100,000 to 1/250,000. In EDS type IV, vascular complications may affect all anatomical areas, with a preference for large- and medium-sized arteries. Dissections of the vertebral and carotid arteries in their extra- and intra-cranial segments are typical. The authors report the case of a patient with EDS type IV for whom the diagnosis was established based on clinical signs and who developed internal carotid artery dissection at the age of 44 years. In the absence of a specific treatment for EDS type IV, medical interventions should focus on symptomatic relief, prophylactic measures, and genetic counseling. Invasive imaging techniques are contraindicated, and a conservative approach to vascular complications is usually recommended.

    The aim of the present study was to investigate the possible associations between dietary energy density (ED) and the metabolic syndrome (MetS) in patients with type 2 diabetes. In the present case-control study, the dietary ED of 125 patients with type 2 diabetes (seventy-eight with (cases) the MetS and forty-seven without (controls) the MetS; mean age 62·0 (SD 9·4) years, mean diabetes duration 12·5 (SD 8·4) years and mean glycated Hb 7·2 (SD 1·3) %) was assessed by weighed diet records. The MetS was defined according to the 2009 Joint Interim Statement and ED by the amount of energy (kJ) in a given weight of food. Data are expressed as means (standard deviations) or medians (interquartile ranges). Patients with the MetS reported lower intakes of total energy and fibre, and a higher total food amount than the controls; the total ED did not differ, but the cases had a higher ED at lunch (mean 6·3 (SD 1·3) v. 5·9 (SD 0·8) kJ/g; P= 0·017). In this meal, patients with the MetS had lower intakes of beans (median 0·7 (interquartile range 0·4-1·1) v. 1·1 (interquartile range 0·6-1·6) g/kg; P= 0·020), vegetables (median 1·2 (interquartile range 0·6-1·7) v. 1·4 (interquartile range 1·0-2·0) g/kg; P= 0·046) and total meat (median 1·3 (interquartile range 1·0-1·6) v. 1·4 (interquartile range 1·2-1·8) g/kg; P= 0·034) than patients without the MetS. The associations between lunch ED (kJ/g) and food groups (g/kg) were confirmed for vegetables (r - 0·584; P< 0·001), fruits (r - 0·233; P= 0·070), beans (r - 0·189; P= 0·037) and oils (r 0·323; P< 0·001). In a multivariate logistic regression model, a high lunch ED was associated with the MetS (OR 6·89, 95 % CI 1·35, 35·15; P =0·020) after adjusting for confounders. In conclusion, a high ED at lunch increased the odds of the presence of the MetS in patients with type 2 diabetes. Beans and vegetables may be the major contributors to this association and their consumption might be

  3. Is 1/f sound more effective than simple resting in reducing stress response?

    It has been previously demonstrated that listening to 1/f sound effectively reduces stress. However, these findings have been inconsistent and further study on the relationship between 1/f sound and the stress response is consequently necessary. The present study examined whether sound with 1/f properties (1/f sound) affects stress-induced electroencephalogram (EEG) changes. Twenty-six subjects who voluntarily participated in the study were randomly assigned to the experimental or control group. Data from four participants were excluded because of EEG artifacts. A mental arithmetic task was used as a stressor. Participants in the experiment group listened to 1/f sound for 5 minutes and 33 seconds, while participants in the control group sat quietly for the same duration. EEG recordings were obtained at various points throughout the experiment. After the experiment, participants completed a questionnaire on the affective impact of the 1/f sound. The results indicated that the mental arithmetic task effectively induced a stress response measurable by EEG. Relative theta power at all electrode sites was significantly lower than baseline in both the control and experimental group. Relative alpha power was significantly lower, and relative beta power was significantly higher in the T3 and T4 areas. Secondly, 1/f sound and simple resting affected task-associated EEG changes in a similar manner. Finally, participants reported in the questionnaire that they experienced a positive feeling in response to the 1/f sound. Our results suggest that a commercialized 1/f sound product is not more effective than simple resting in alleviating the physiological stress response.

    The coexistence of polyneuropathy which has the definite clinical and electromyographical findings consistent with Charcot-Marie-Tooth (CMT) syndrome and neurofibromatosis type 1 (NF1) has infrequently been reported. We describe a patient with both CMT and NF1, who had multiple neurofibromas involving the entire spinal neural axis. In addition, he had multiple neurofibromas distributed within the ileopsoas and gluteus muscles and subcutaneous tissues. These lesions were detected readily by MRI and the patient underwent successful surgical resection of the largest tumours compressing bilateral C2 nerve roots. To our knowledge, this is the first reported case of CMT syndrome coexisting with NF1 in which multiple neurofibromas involved the entire spinal nerve roots. We discuss the diagnostic and therapeutic challenges, emphasising the role of MRI and electrophysiology in such cases and provide a literature review.

    2012-01-01

    Full Text Available The distinction between the Ehlers-Danlos syndrome hypermobile type (EDSH and the benign joint hypermobility syndrome (BJHS is unclear. The aim of the present study was to compare skin ultrastructural abnormalities of EDSH and BJHS among different families. Skin of 23 EDSH, 27 BJHS, and 41 asymptomatic subjects from 17 families was examined using transmission electron microscopy. Similar ultrastructural abnormalities were found irrespective of the Beighton score. Flower-like collagen fibrils represented the key change and elastic fibers were altered as well. Beighton score is a clinical parameter rating joint mobility that appeared unrelated to quantitative and qualitative collagen ultrastructural alterations in the skin. Some EDSH family members fit with BJHS diagnosis. BJHS possibly represents a mild variant of EDSH.

    Full Text Available Elhers-Danlos syndrome (EDS is the clinical manifestation of connective tissue disorders, and comprises several clinical forms with no specific symptoms and selective medical examinations which result in a delay in diagnosis of about 10 years. The EDS hypermobility type (hEDS is characterized by generalized joint hypermobility, variable skin hyperextensibility and impaired proprioception. Since somatosensory processing and multisensory integration are crucial for both perception and action, we put forth the hypothesis that somatosensory deficits in hEDS patients may lead, among other clinical symptoms, to misperception of verticality and postural instability. Therefore, the purpose of this study was twofold: (i to assess the impact of somatosensory deficit on subjective visual vertical (SVV and postural stability; and (ii to quantify the effect of wearing somatosensory orthoses (i.e., compressive garments and insoles on postural stability. Six hEDS patients and six age- and gender-matched controls underwent a SVV (sitting, standing, lying on the right side evaluation and a postural control evaluation on a force platform (Synapsys, with or without visual information (eyes open (EO/eyes closed (EC.

The EDS hypermobility type (hEDS) is characterized by generalized joint hypermobility, variable skin hyperextensibility and impaired proprioception. Since somatosensory processing and multisensory integration are crucial for both perception and action, we put forth the hypothesis that somatosensory deficits in hEDS patients may lead, among other clinical symptoms, to misperception of verticality and postural instability. Therefore, the purpose of this study was twofold: (i) to assess the impact of somatosensory deficit on subjective visual vertical (SVV) and postural stability; and (ii) to quantify the effect of wearing somatosensory orthoses (i.e., compressive garments and insoles) on postural stability. Six hEDS patients and six age- and gender-matched controls underwent a SVV (sitting, standing, lying on the right side) evaluation and a postural control evaluation on a force platform (Synapsys), with or without visual information (eyes open (EO)/eyes closed (EC)). These two latter conditions performed either without orthoses, or with compression garments (CG), or insoles, or both. Results showed that patients did not exhibit a substantial perceived tilt of the visual vertical in the direction of the body tilt (Aubert effect) as did the control subjects. Interestingly, such differential effects were only apparent when the rod was initially positioned to the left of the vertical axis (opposite the longitudinal body axis). In addition, patients showed greater postural instability (sway area) than the controls. The removal of vision exacerbated this instability, especially in the mediolateral (ML) direction. The wearing of orthoses improved postural stability, especially in the eyes-closed condition, with a particularly

    To investigate whether orthostatic intolerance (OI) is a significant predictor for fatigue in Ehlers-Danlos Syndrome, hypermobility type (EDS-HT). Eighty patients with EDS-HT and 52 controls participated in the first part of the study, which consisted of questionnaires. Fatigue was evaluated using the Checklist Individual Strength (CIS). As possible fatigue determinants OI [Autonomic Symptom Profile (ASP)], habitual physical activity (Baecke), affective distress [Hospital Anxiety and Depression Scale (HADS)], pain (SF36), medication use and generalized hypermobility (5-point score of Grahame and Hakim regarding generalized joint hypermobility) were studied. Next, a 20 min head-up tilt (70°) was performed in a subsample of 39 patients and 35 controls, while beat-to-beat heart rate and blood pressure were monitored (Holter, Finometer Pro). Before and after tilt, fatigue severity was assessed using a numeric rating scale. Patients scored significantly higher on the CIS [total score: EDS: 98.2 (18.63) vs controls: 45.8 (16.62), P < 0.001] and on the OI domain of the ASP [EDS: 22.78 (7.16) vs controls: 6.5 (7.78)]. OI was prevalent in EDS-HT (EDS: 74.4%, controls: 34.3%, P = 0.001), and frequently expressed as postural orthostatic tachycardia (41.0% of the EDS group). Patients responded to tilt with a higher heart rate and lower total peripheral resistance (p < 0.001; p = 0.032). This altered response correlated with fatigue in daily life (CIS). In the EDS-HT group, tilt provoked significantly more fatigue [numeric rating scale increase: EDS: +3.1 (1.90), controls: +0.5 (1.24), P < 0.001]. Furthermore, the factors OI, pain, affective distress, decreased physical activity and sedative use explained 47.7% of the variance in fatigue severity. OI is an important determinant of fatigue in EDS-HT. © The Author 2016. Published by Oxford University Press on behalf of the British Society for Rheumatology. All rights reserved.

    Full Text Available ObjectiveTo investigate the clinical efficacy of domestic terlipressin in the treatment of type II hepatorenal syndrome (HRS-II. MethodsA total of 25 HRS-II patients admitted to our hospital from November 2011 to June 2014 were recruited into the treatment group, and 28 HRS-II patients treated with dopamine before 2011 were recruited into the control group. Patients in the treatment group were randomly divided into two subgroups: one subgroup (n=12 was given terlipressin once every 8 h, and the other subgroup (n=13 was given terlipressin once every 12 h. Both groups received albumin (Alb infusion to expand the blood volume before treatment with terlipressin or dopamine, and the course of treatment was 7 days. The improvement in clinical symptoms, levels of blood urea nitrogen (BUN, serum creatinine and electrolytes, urine volume, changes in liver function, and ascites disappearance in the two groups before and after treatment were compared. Comparison of categorical data between the two groups was made by χ2 test, and comparison of continuous data was made by t test. ResultsPatients in the control group showed no obvious symptom relief, but those in the treatment group had varying degrees of improvement in clinical symptoms. Neither group had significant changes in liver function and serum sodium level after treatment. The treatment group had significantly more patients whose ascites volume had decreased from large to medium than the control group (χ2=5.705, P<0.05. There was a slight but not significant decrease in the levels of BUN and serum creatinine in the control group after treatment with dopamine (all P>0.05, whereas the urine volume showed significant difference after the treatment (t=15.534, P<0.01. The treatment group showed significant differences in the levels of BUN and serum creatinine and urine volume after terlipressin treatment (t=11.535, 9.941, and 19.685, respectively; all P<0.01, and significant differences in

    Background Dimethylsulfoxide (DMSO) is the most-used agent for intravesical instillation. We conducted this retrospective clinical study to determine in what type of the interstitial cystitis (IC)/bladder pain syndrome (BPS) DMSO was effective. Methods We combined DMSO with hydrodistension in 2003 and from 2004 we performed hydrodistension alone. Hydrodistension had been performed in 7 cases of IC/BPS with Hunner’s lesions (H group) and 7 cases of IC/BPS without Hunner’s lesions (non-H group), and they served as the control group (C group; n=14). There was also a DMSO group (D group; n=14) that consisted of an H group of 7 cases and an non-H group of 7 cases in which the hydrodistension had been immediately followed by intravesical instillation of 50% DMSO 50 mL. Before, and 2, 6, 12, 18, and 24 months (M) after the intervention, the patients were asked to complete a 4-day frequency-volume chart (FVC) and the O’Leary-Sant IC symptom index (ICSI) questionnaire and IC problem index (ICPI) questionnaire, and to rate their pain on a visual analogue scale (VAS). Results All parameters were improved after hydrodistension in both the C group and the D group. However, comparison of the C group and D group according to whether Hunner lesions were present showed that there were no significant differences in any of the postoperative parameters between the non-H groups in the C group and D group, but in the H groups, average and maximum voided volume were significantly higher and the ICSI, ICPI, and VAS scores were lower in the D group. Moreover, the significant differences increased with the duration of the postoperative period. Conclusions DMSO intravesical instillation therapy was useful in both maintaining and improving the effectiveness of hydrodistension in IC/BPS with Hunner lesions. However, DMSO did not have any particular efficacy in the treatment of IC/BPS in the absence of Hunner lesions. PMID:26816859

    Clinical trials have studied the use of soy protein for treating type 2 diabetes (T2D) and metabolic syndrome (MS). The purpose of this study was to outline evidence on the effects of soy protein supplementation on clinical indices in T2D and MS subjects by performing a meta-analysis of randomized controlled trials (RCTs). We searched PubMed, EMBASE, and Cochrane databases up to March 2015 for RCTs. Pooled estimates and 95% confidence intervals (CIs) were calculated by the fixed-and-random-effects model. A total of eleven studies with eleven clinical variables met the inclusion criteria. The meta-analysis showed that fasting plasma glucose (FPG) [weighted mean difference (WMD), -0.207; 95% CI, -0.374 to -0.040; p=0.015], fasting serum insulin (FSI) (WMD, -0.292; 95% CI, -0.496 to -0.088; p=0.005), homeostasis model of assessment for insulin resistance index (HOMA-IR) (WMD, -0.346; 95% CI, -0.570 to -0.123; p=0.002), diastolic blood pressure (DBP) (WMD, -0.230; 95% CI, -0.441 to -0.019; p=0.033), low-density lipoprotein cholesterol (LDL-C) (WMD, -0.304; 95% CI, -0.461 to -0.148; p=0.000), total cholesterol (TC) (WMD, -0.386; 95% CI, -0.548 to -0.225; p=0.000), and C-reactive protein (CRP) (WMD, -0.510; 95% CI, -0.722 to -0.299; p=0.000) are significant reduced with soy protein supplementation, compared with a placebo control group, in T2D and MS patients. Furthermore, soy protein supplementation for longer duration (≥6 mo) significantly reduced FPG, LDL-C, and CRP, while that for a shorter duration (protein supplementation could be beneficial for FPG, FSI, HOMA-IR, DBP, LDL-C, TC, and CRP control in plasma.

    Autoimmune polyglandular syndrome type 3 - (APS-3), is defined as the coexistence of autoimmune thyroiditis with other non-ovarian autoimmune diseases without primary adrenal insufficiency. Additionally the definition of APS-3 also includes primary ovarian insufficiency (POI) coexistence with autoimmune thyroiditis. The main goal of that study is to assess the prevalence of APS-3 defined as coexistence of autoimmune thyroiditis with POI in population of 46 XX karyotype women with primary ovarian insufficiency (POI). The second goal is to investigate hormonal profile and insulin sensitivity in women with POI and subgroups of women with APS-3 - POI/APS-3(+) and without APS 3 - POI/APS-3(-). Anthropometric measurements, coexistence of autoimmune diseases, androgens, fasting glucose and insulin, glucose and insulin at 60' and 120' of oral glucose tolerance test (OGTT) and homeostasis model for insulin resistance (HOMA-IR), were determine in 98 patients aged between 18 and 39 with spontaneous 46 XX primary ovarian insufficiency (POI), in 33 POI/APS-3(+), 65 POI/APS-3(-), and 75 healthy controls. Continuous data were summarized by the mean±standard deviation (SD), and categorical data by number (percentages). Data were checked for normality using Shapiro-Wilk test, the comparison between groups were performed using non-parametric Mann-Whitney or Kruskall-Wallis test. Pearson's correlation coefficient was used to assess the relationships between parameters. Statistical significance was defined as p values APS-3(+) and POI/APS-3(-) showed significantly lower serum androgens in comparison to controls. Additionally women with POI/APS-3(+) showed hyperinsulinemia after 1h of OGTT; No significant differences in serum fasting glucose, insulin and during 2h OGTT between groups were observed. The prevalence of APS-3 is 33.7% in patients with spontaneous 46 XX primary ovarian insufficiency. Women with POI, POI/APS-3(+) and POI/APS-3(-) feature lower testosterone, androstendione

    Objectives: The aim of this study was to evaluate liver function in patients with type 2 diabetes mellitus (T2DM) with and without metabolic syndrome (MS) by determining serum levels of gamma glutamyltransferase (GGT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). We also investigated correlation between levels of liver enzymes and some components of MS in both groups of patients. Methods: This cross-sectional study included 96 patients (age 47–83 years) with T2DM. All patients were divided according to the criteria of the National Cholesterol Education Program (NCEP) in two groups: 50 patients with T2 DM and MS (T2DM-MS) and 46 patients with T2DM without MS (T2DM-Non MS). The analysis included blood pressure monitoring and laboratory tests: fasting blood glucose (FBG), total lipoprotein cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), fibrinogen and liver enzymes: GGT, ALT and AST. T2DM-MS group included patients which had FBG ≥ 6,1 mmol/L, TG ≥ 1,7 mmol/L and blood pressure ≥ 130/85 mm Hg. Results: T2DM-MS patients had significant higher values of systolic blood pressure, diastolic blood pressure and medium arterial pressure compared to T2DM-Non MS patients. Serum levels of TC, TG, LDL-C, VLDL-C and FBG were significantly higher in the T2DM-MS group compared to the T2DM-Non MS group. Serum fibrinogen level and GGT level were significantly higher in patients with T2DM-MS compared to the serum fibrinogen level and GGT level in T2DM-Non MS patients. Mean serum AST and ALT level were higher, but not significantly, in patients with T2DM and MS compared to the patients with T2DM without MS. Significant negative correlations were observed between TC and AST (r= -0,28, p<0,05), as well as between TC and ALT level (r= -0,29, p<0,05) in T2DM-MS group of patients. Conclusion: These results suggest that patients with T2DM and MS have markedly elevated liver enzymes. T2DM and MS probably play a role in

    Wolfram syndrome (WFS) is diagnosed as coexistence of diabetes mellitus and optic atrophy, where pancreatic beta cell destruction is associated with neurodegeneration. Typically, WFS necessitates insulin treatment similar to type 1 diabetes (T1D), but the mechanism of beta cell mass reduction leading to hyperglycemia is different. The aim of the study was to assess glycemic variability using the continuous glucose monitoring (CGM) system in seven pediatric patients with genetically confirmed WFS and compare the results with data obtained from 21 propensity score-matched patients with T1D. The "GlyCulator" application was used for the calculation of glycemic variability indices. CGM recordings showed similarities in glycemic variability among WFS patients, but differing from those of the T1D group. Coefficient of variation (%CV), CONGA4h, and GONGA6h were significantly (p < 0.05) lower in WFS patients (28.08 ± 7.37, 54.96 ± 11.92, and 55.99 ± 10.58) than in T1D patients (37.87 ± 14.24, 74.12 ± 28.74, p = 0.02, and 80.26 ± 35.05, respectively). In WFS patients, the percentage of values above 126 mg/dL was 69.79 (52.08-77.43), whereas in patients with T1D, the percentage was significantly lower-47.22 (35.07-62.85, p = 0.018). Curiously, a tendency toward a lower percentage of measurements below 70 mg/dL was noted in the WFS group [0 (0-7.29)] in comparison with the T1D group [6.25 (0-18.06), p = 0.122]. WFS patients had a significantly higher C-peptide level (0.31 ± 0.2 ng/mL) than T1D patients (0.04 ± 0.04 ng/mL; p = 0.006). Patients with WFS show smaller glycemic variability than individuals with T1D, and this may be associated with persistent residual insulin secretion.

    The BCM1F system used in the CMS is used for measuring the beam-background and more importantly the real time luminosity and sits 1.8 m from the interaction point (IP5).There has been a proposal to upgrade the BCM1F when it would be installed for the LHC run in 2014. The BCM1F is fitted with Analog Opto-Hybrid(AOH) boards which consists of three Linear Laser Drivers (LLD) and three laser diodes. These AOH boards are affected by radiation and temperature in a long term and short term respectively. This paper studies the characteristics and behavior of these AOH boards.

    The bond between the 1/f-noise and the critical state self-organization is considered theoretically and through the computerized simulation method by the example of the model of the multicontact SKUID, placed in the external magnetic field. It is shown that there exists the wide 1/f-noise area, in the medium current spectra of the various dimension systems, limited only by the system dimension. However the existence of the 1/f-noise and the critical state self-organization was observed only in one system in the two-dimensional case

    Probability distributions that emerge from the formalism of nonextensive statistical mechanics have been applied to a variety of problems. In this article we unite modeling of such distributions with the model of widespread 1/f noise. We propose a class of nonlinear stochastic differential equations giving both the q-exponential or q-Gaussian distributions of signal intensity, revealing long-range correlations and 1/f(β) behavior of the power spectral density. The superstatistical framework to get 1/f(β) noise with q-exponential and q-Gaussian distributions of the signal intensity is proposed, as well.
