    Full Text Available Abstract Background Mental deficiency has been linked to abnormalities in cortical neuronal network connectivity and plasticity. These mechanisms are in part under the control of two interacting signalling pathways, the serotonergic and the brain-derived neurotrophic (BDNF pathways. The aim of the current paper is to determine whether particular alleles or genotypes of two crucial genes of these systems, the serotonin transporter gene (SLC6A4 and the brain-derived neurotrophic factor gene (BDNF, are associated with mental deficiency (MD. Methods We analyzed four functional polymorphisms (rs25531, 5-HTTLPR, VNTR, rs3813034 of the SLC6A4 gene and one functional polymorphism (Val66 Met of the BDNF gene in 98 patients with non-syndromic mental deficiency (NS-MD and in an ethnically matched control population of 251 individuals. Results We found no significant differences in allele and genotype frequencies in the five polymorphisms studied in the SLC6A4 and BDNF genes of NS-MD patients versus control patients. While the comparison of the patterns of linkage disequilibrium (D' in the control and NS-MD populations revealed a degree of variability it did not, however, reach significance. No significant differences in frequencies of haplotypes and genotypes for VNTR/rs3813034 and rs25531/5-HTTLPR were observed. Conclusion Altogether, results from the present study do not support a role for any of the five functional polymorphisms of SLC6A4 and BDNF genes in the aetiology of NS-RM. Moreover, they suggest no epistatic interaction in NS-MD between polymorphisms in BDNF and SLC6A4. However, we suggest that further studies on these two pathways in NS-MD remain necessary.

    Most mitochondrial and cytoplasmic aminoacyl-tRNA synthetases (aaRSs) are encoded by nuclear genes. Syndromic disorders resulting from mutation of aaRSs genes display significant phenotypic heterogeneity. We expand aaRSs-related phenotypes through characterization of the clinical and molecular basis of a novel autosomal-recessive syndrome manifesting severe mental retardation, ataxia, speech impairment, epilepsy, short stature, microcephaly, hypogonadism, and growth hormone deficiency.A G>A variant in exon 29 of VARS2 (c.3650G>A) (NM_006295) was identified in the index case. This homozygous variant was confirmed by Sanger sequencing and segregated with disease in the family studied. The c.3650G>A change results in alteration of arginine to histidine at residue 1217 (R1217H) of the mature protein and is predicted to be pathogenic.These findings contribute to a growing list of aaRSs disorders, broadens the spectrum of phenotypes attributable to VARS2 mutations, and provides new insight into genotype-phenotype correlations among the mitochondrial synthetase genes.

    Constitutional mismatch repair deficiency (CMMR-D) syndrome is characterised by a significantly increased risk for developing cancer in childhood. It arises when both parents have a mutation in the same mismatch repair gene and pass it on to their child. An 8-year-old girl was diagnosed with CMMR-D syndrome after she developed a brain tumour at the age of 4 and a T-cell non-Hodgkin lymphoma at the age of 6. She had multiple hyperpigmented skin lesions and died of myelodysplastic syndrome at the age of 11. In children with cancer CMMR-D syndrome can be recognized particularly if there are multiple primary malignancies and skin hyperpigmentations and hypopigmentations. The parents of these children are at high risk for colorectal and endometrial cancer (Lynch syndrome), amongst others.

    Baraitser-Winter syndrome (BWS), first reported in 1988, is apparently due to genetic abnormalities that are still not well-defined, although many gene abnormalities are already discovered and de novo missense changes in the cytoplasmic actin-encoding genes (called ACTB and ACTG1) have been recently discovered. The syndrome combines facial and cerebral malformations. Facial malformations totally or partially present in the same patient are: Iris coloboma, bilateral ptosis, hypertelorism, broad nasal bridge, and prominent epicanthic folds. The various brain malformations are probably responsible for growth and mental retardation. To the best of our knowledge, the syndrome is very rare as few cases have been reported so far. Our aim was to describe a child with a phenotype that looks like BWS with proved partial growth hormone (GH) deficiency which was not reported before. A girl aged 7-year-old of consanguineous parents was referred for short stature and mental retardation. Clinical examination showed dwarfism and a delay in her mental development. Other clinical features included: Strabismus, epicanthic folds, broad nasal bridge, and brain anomalies such as lissencephaly, bilateral hygroma, and cerebral atrophy. Hormonal assessment showed partial GH deficiency without other endocrine disorders. Our case looks exactly like BWS. However, apart from facial and cerebral abnormalities, there is a partial GH deficiency which can explain the harmonious short stature. This case seems worth to be reported as it adds GH deficiency to the very rare syndrome.

    Phosphorylated creatine (Cr) serves as an energy buffer for ATP replenishment in organs with highly fluctuating energy demand. The central role of Cr in the brain and muscle is emphasized by severe neurometabolic disorders caused by Cr deficiency. Common symptoms of inborn errors of creatine synthesis or distribution include mental retardation and muscular weakness. Human mutations in l-arginine:glycine amidinotransferase (AGAT), the first enzyme of Cr synthesis, lead to severely reduced Cr and guanidinoacetate (GuA) levels. Here, we report the generation and metabolic characterization of AGAT-deficient mice that are devoid of Cr and its precursor GuA. AGAT-deficient mice exhibited decreased fat deposition, attenuated gluconeogenesis, reduced cholesterol levels and enhanced glucose tolerance. Furthermore, Cr deficiency completely protected from the development of metabolic syndrome caused by diet-induced obesity. Biochemical analyses revealed the chronic Cr-dependent activation of AMP-activated protein kinase (AMPK), which stimulates catabolic pathways in metabolically relevant tissues such as the brain, skeletal muscle, adipose tissue and liver, suggesting a mechanism underlying the metabolic phenotype. In summary, our results show marked metabolic effects of Cr deficiency via the chronic activation of AMPK in a first animal model of AGAT deficiency. In addition to insights into metabolic changes in Cr deficiency syndromes, our genetic model reveals a novel mechanism as a potential treatment option for obesity and type 2 diabetes mellitus.

    Normal functioning of the human body requires a balance between nutritional intake and metabolism, and imbalances manifest as nutritional deficiencies or excess. Nutritional deficiency states are associated with social factors (war, poverty, famine, and food fads), medical illnesses with malabsorption (such as Crohn disease, cystic fibrosis, and after bariatric surgery), psychiatric illnesses (eating disorders, autism, alcoholism), and medications. Nutritional excess states result from inadvertent or intentional excessive intake. Cutaneous manifestations of nutritional imbalance can herald other systemic manifestations. This contribution discusses nutritional deficiency and excess syndromes with cutaneous manifestations of particular interest to clinical dermatologists. Copyright © 2010. Published by Elsevier Inc.

    Full Text Available The aim of this paper is to present, from penological aspect, the involvement and structure of recidivism at minors with mental deficiency within the whole area of juvenile criminality in Macedonia. The research covers 62 subjects who pay the penalty in juvenile penitentiary or institutional measure directing to correctional institution for minors. Of the total number of minors who hold one of the above-mentioned sanctions, minors with lower average IQ are presented with 56.4%. The shown involvement is in penological terms (refers to minors who hold institutional measure correctional institution for minors or penalty - juvenile penitentiary which does not mean that this category of juvenile delinquents participate in such percent in the total number of reported, accused and convicted minors. According to the research results it can be concluded that falling behind in intellectual development is an indicator for delinquent behavior but in no case it can be crucial or the most important factor for criminality. Of the total number of juvenile delinquents with intellectual deficit, 80% are repeat offenders in criminal legal sense. It is of great concern that 56% of the under average juvenile delinquents defied the law for the first time before the age of 14 years that is as children.

    Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

    We report a 20-year-old man with gigantism syndrome, hypertrophic cardiomyopathy, muscle weakness, exercise intolerance, and severe psychomotor retardation since childhood. Histochemical and biochemical analysis of skeletal muscle biopsy revealed myoadenylate deaminase deficiency; molecular genetic analysis confirmed the diagnosis of primary (inherited) myoadenylate deaminase deficiency. Plasma, urine, and muscle carnitine concentrations were reduced. L-Carnitine treatment led to gradual improvement in exercise tolerance and cognitive performance; plasma and tissue carnitine levels returned to normal, and echocardiographic evidence of left ventricular hypertrophy disappeared. The combination of inherited myoadenylate deaminase deficiency, gigantism syndrome and carnitine deficiency has not previously been described.

    Bartter syndrome is a rare autosomal recessive disorder characterized by hypokalemia, salt loss, and metabolic alkalosis. Short stature is one of the clinical manifestations in these children. Although polyuria, polydipsia, hypokalemia, and salt loss may be responsible for growth retardation, the exact pathogenesis of short stature in Bartter syndrome is not known. In this study, we present three children diagnosed as having Bartter syndrome with short stature and growth hormone (GH) deficiency. After recombinant human growth hormone therapy (rhGH), their growth velocities were improved. These results indicate that GH deficiency may contribute to short stature in children with Bartter syndrome, and rhGH therapy would be an excellent adjunctive treatment for short children with this syndrome whose condition is resistant to conventional therapies in terms of growth.

  20. Mevalonate kinase deficiencies: from mevalonic aciduria to hyperimmunoglobulinemia D syndrome

    2006-04-01

    Full Text Available Abstract Mevalonic aciduria (MVA and hyperimmunoglobulinemia D syndrome (HIDS represent the two ends of a clinical spectrum of disease caused by deficiency of mevalonate kinase (MVK, the first committed enzyme of cholesterol biosynthesis. At least 30 patients with MVA and 180 patients with HIDS have been reported worldwide. MVA is characterized by psychomotor retardation, failure to thrive, progressive cerebellar ataxia, dysmorphic features, progressive visual impairment and recurrent febrile crises. The febrile episodes are commonly accompanied by hepatosplenomegaly, lymphadenopathy, abdominal symptoms, arthralgia and skin rashes. Life expectancy is often compromised. In HIDS, only febrile attacks are present, but a subgroup of patients may also develop neurological abnormalities of varying degree such as mental retardation, ataxia, ocular symptoms and epilepsy. A reduced activity of MVK and pathogenic mutations in the MVK gene have been demonstrated as the common genetic basis in both disorders. In MVA, the diagnosis is established by detection of highly elevated levels of mevalonic acid excreted in urine. Increased levels of immunoglobulin D (IgD and, in most patients of immunoglobulin A (IgA, in combination with enhanced excretion of mevalonic acid provide strong evidence for HIDS. The diagnosis is confirmed by low activity of mevalonate kinase or by demonstration of disease-causing mutations. Genetic counseling should be offered to families at risk. There is no established successful treatment for MVA. Simvastatin, an inhibitor of HMG-CoA reductase, and anakinra have been shown to have beneficial effect in HIDS.

    Tuberculosis and the acquired immune deficiency syndrome in South Brazil. The authors studied the incidence of tuberculosis in South Brazilian patients with acquired immune deficiency syndrome from January 1985 to June 1988. During this period, tuberculosis occurred in 10.3% of acquired immune deficiency syndrome patients. The socioeconomic conditions and the incidence of disease in the population were not confirmed as a potential risk for tuberculosis infection. Chest radiographs revealed pulmonary infiltrates in six patients, hilar and/or mediastinal adenopathy in three, and pleural effusion in two. The two remaining patients had pulmonary consolidation associated with other features. None of these patients presented pulmonary cavitation or radiographic findings of typical reactivation of pulmonary tuberculosis. (author) [pt

    There is virtually no correlation between what are generally accepted to be the symptoms of deficient androgen in men and levels of androgens as measured in the laboratory. Now that androgen deficiency is being shown to play a part in conditions as diverse as metabolic syndrome, diabetes, and coronary heart disease, a hypothesis is needed to explain this apparent discrepancy between measured androgen levels and our understanding of the symptoms of androgen deficiency. When the possible mechanisms for androgen actions are considered, one explanation emerges that androgen may act much like insulin in persons with type 2 diabetes mellitus: the degree of androgen resistance may be variable depending on the organs or systems considered. Therefore, the symptoms can result from altered or damaged synthesis of androgen synthesis or regulation, elevated androgen binding, a reduction in tissue response, or decreased as a result of polymorphism and aging. Genomic transcription and translation may also be affected. As with diabetes, in adult male androgen deficiency, it is suggested that the definition of androgen deficiency should be based on individual physiology, with the requirements of the individual at a particular stage of life setting the baseline against which any deficiency of androgens or androgen metabolites, either absolute or relative, is determined. This approach will affect the terminology, etiology, diagnosis, and treatment of androgen deficiency.

    Mental and behavioral disorders among adults with Usher syndrome have been discussed and reported in some case studies but no research has been reported on children with Usher syndrome. This article investigates the prevalence and characteristics of mental and behavioral disorders among 26 children, 3-17 years of age, with Usher syndrome. Six of the 26 children were diagnosed with a mental or behavioral disorder (1 with schizophrenia and mild mental retardation, 1 with atypical autism and severe mental retardation, 1 with atypical autism and mild mental retardation, 1 with mild mental retardation, and 2 with conduct disorder). Another 3 children had had a mental or behavioral disorder previously in their childhood. Even though vision impairment first manifests in late childhood, some children with Usher syndrome seem to develop mental and behavioral disorders during childhood. The aetiology and treatment of mental and behavioral disorders among children with Usher syndrome are discussed. Children with Usher syndrome and their parents may need clinical support during early childhood to prevent development of mental and behavioral disorders.

It was first described over a century ago. However, literature on this condition remains scanty, and its prevalence appears to be declining worldwide, possibly due to improvements in nutrition over time. The condition has been reported most commonly in thin-built, middle-aged, white women. The esophageal webs in PVS are thin mucosal folds, which are best seen either in lateral views at barium swallow or at esophagoscopy. These are usually semilunar or crescentic, being located most often along the anterior esophageal wall, but can be concentric. The exact cause and pathogenesis of PVS remain unclear, though iron and other nutritional deficiencies, genetic predisposition and autoimmunity have all been implicated in formation of the webs. Treatment includes correction of iron deficiency and endoscopic dilation of the esophageal webs to relieve dysphagia. PVS is associated with an increased risk of hypopharyngeal and esophageal malignancies. Correction of iron deficiency may arrest and reverse the mucosal changes and possibly reduces this risk.

    GLUT-1 deficiency syndrome (GLUT-1 DS) is a disorder of cerebral glucose transport associated with early infantile epilepsy and microcephaly. We report two boys who presented with refractory absence epilepsy associated with hypoglycorrhachia, both of whom have genetically confirmed GLUT-1 DS. We propose that these children serve to expand the phenotype of GLUT-1 DS and suggest that this condition should be considered as a cause of refractory absence seizures in childhood.

    To detect the expression of the peripheral blood P2X5 receptor at various ambient temperatures, and to explore its relationship with deficiency-cold syndrome and deficiency-heat syndrome. Subjects were selected by questionnaire and expert diagnosis, and assigned to the normal control group, the deficiency-cold syndrome group, and the deficiency-heat syndrome group, 20 in each group. 5 mL venous blood was collected at room temperature (25 °C) and cold temperature (-4-5 °C) respectively. Then the expression of P2X5 receptor was relatively quantified by real-time fluorescence quantitative PCR, and compared at room temperature and cold temperature respectively. The expression of P2X5 receptor in deficiency-cold syndrome and deficiency-heat syndrome groups was lower than that in the normal control group at room temperature (P cold temperature in the deficiency-cold syndrome group than in the normal control group (P receptor showed no difference in all groups at two different temperatures (P > 0.05). The expression of P2X5 receptor was different in different syndrome groups at various ambient temperatures. Ambient temperatures had insignificant effect on the expression of P2X5 receptor of the population with the same syndrome.

    Biallelic germline mutations in the mismatch repair genes MLH1, MSH2, MSH6 or PMS2 cause a recessive childhood cancer syndrome characterised by early-onset malignancies and signs reminiscent of neurofibromatosis type 1 (NF1). Alluding to the underlying genetic defect, we refer to this syndrome as constitutional mismatch repair-deficiency (CMMR-D) syndrome. The tumour spectrum of CMMR-D syndrome includes haematological neoplasias, brain tumours and Lynch syndrome-associated tumours. Other tumours, such as neuroblastoma, Wilm tumour, ovarian neuroectodermal tumour or infantile myofibromatosis, have so far been found only in individual cases. We analysed two consanguineous families that had members with suspected CMMR-D syndrome who developed rhabdomyosarcoma among other neoplasias. In the first family, we identified a pathogenic PMS2 mutation for which the affected patient was homozygous. In family 2, immunohistochemistry analysis showed isolated loss of PMS2 expression in all tumours in the affected patients, including rhabdomyosarcoma itself and the surrounding normal tissue. Together with the family history and microsatellite instability observed in one tumour this strongly suggests an underlying PMS2 alteration in family 2 also. Together, these two new cases show that rhabdomyosarcoma and possibly other embryonic tumours, such as neuroblastoma and Wilm tumour, belong to the tumour spectrum of CMMR-D syndrome. Given the clinical overlap of CMMR-D syndrome with NF1, we suggest careful examination of the family history in patients with embryonic tumours and signs of NF1 as well as analysis of the tumours for loss of one of the mismatch repair genes and microsatellite instability. Subsequent mutation analysis will lead to a definitive diagnosis of the underlying disorder.

    Background: Metabolic syndrome is commonly associated with cardiovascular diseases and psychiatric mental illness. Hence, we aimed to assess the metabolic syndrome among severe mental illness (SMI). Materials and Methods: The study included 267 patients who were referred to the psychiatric unit at 5th Azar Education Hospital of Golestan University of Medical Sciences in Gorgan, Iran. Results: The mean waist circumference, systolic and diastolic blood pressure, triglyceride and fasting blood glucose levels were significantly higher in the SMI with metabolic syndrome, but the high density lipoprotein (HDL)-cholesterol was significantly lower. The prevalence of metabolic syndrome in SMI patients was 20.60%. There were significant differences in the mean of waist circumference, systolic (except for women) and diastolic blood pressure, triglyceride, HDL-cholesterol and fasting blood glucose in men and women with metabolic syndrome when compared with subjects without metabolic syndrome. The prevalence of metabolic syndrome in SMI women was higher than men. The most age distribution was in range of 30-39 years old. The most prevalence of metabolic syndrome was in age groups 50-59 years old. The prevalence of metabolic syndrome was increased from 30 to 59 years old. Conclusion: The prevalence of metabolic syndrome in patients with SMI in Gorgan is almost similar to those observed in Asian countries. The prevalence of metabolic syndrome was lower than western countries. These observations may be due to cultural differences in the region. It should be mention that the families of mental illness subjects in our country believe that their patients must be cared better than people without mental illness. These findings of this study suggest that mental illness patients are at risk of metabolic syndrome. According to our results, risk factors such as age and gender differences may play an important role in the presence of metabolic syndrome. In our country, women do less

    Growth hormone deficiency (GHD) in adults is characterized by reduced quality of life and physical fitness, skeletal fragility, increased weight and cardiovascular risk. It may be found in (over-) treated acromegaly as well as in active Cushing's syndrome. Hypopituitarism may develop in patients after definitive treatment of acromegaly, although the exact prevalence of GHD in this population is still uncertain because of limited awareness, and scarce and conflicting data so far available. Because GHD associated with acromegaly and Cushing's syndrome may yield adverse consequences on similar target systems, the final outcomes of some complications of both acromegaly and Cushing's syndrome may be further affected by the occurrence of GHD. It is still largely unknown, however, whether GHD in patients with post-acromegaly or active Cushing's syndrome (e.g. pharmacologic glucocorticoid treatment) may benefit from GH replacement. We review the diagnostic, clinical and therapeutic aspects of GHD in adults treated for acromegaly and in those with active Cushing's syndrome. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Hunter syndrome is a rare X-linked recessive disorder caused by deficiency of the lysosomal enzyme iduronate-2-sulphatase, leading to progressive accumulation of a substance called glycosaminoglycans in nearly all cell types, tissues, and organs. Hunter syndrome presents with facial dysmorphism, airway diseases, skeletal defects, cardiomyopathies, and neuropsychiatric manifestations. Mental subnormality is a cardinal feature in Hunter syndrome. This is a progressive cognitive decline that is not amenable to enzyme replacement therapy. Due to progressive cognitive decline, training the children to improve the adaptive functioning is a challenge that creates immense stress for the caregivers. Patients with Hunter syndrome should undergo serial assessment of intellectual ability and may be trained accordingly.

Although there have been recent developments in understanding the pathophysiology of RLS, the exact mechanism of the disease has not been well elucidated. An increased prevalence of neurologic and psychiatric diseases involving dopaminergic dysfunction in vitamin D-deficient patients led us to hypothesize that vitamin D deficiency might result in dopaminergic dysfunction and consequently, the development of RLS (in which dopaminergic dysfunction plays a pivotal role. Thus, the aim of this study was to evaluate the relationship between vitamin D deficiency and RLS. Methods: One hundred and fifty-five consecutive patients, 18–65 years of age, who were admitted to the Department of Internal Medicine with musculoskeletal symptoms and who subsequently underwent neurological and electromyography (EMG examination by the same senior neurologist, were included in this study. The patients were divided into two groups according to serum 25-hydroxyvitamin D (25(OHD (a vitamin D metabolite used as a measure of vitamin D status level: 36 patients with serum 25(OHD levels ≥20 ng/mL comprised the normal vitamin D group, and 119 patients with serum 25(OHD levels <20 ng/mL comprised the vitamin D deficiency group. The two groups were compared for the presence of RLS and associated factors. Results: The two groups were similar in terms of mean age, sex, mean body mass index (BMI, and serum levels of calcium, phosphate, alkaline phosphatase (ALP, and ferritin. The presence of RLS was significantly higher in the vitamin D deficiency group (χ2=12.87, P<0

    Lynch syndrome is the most common form of hereditary colorectal carcinoma. However, establishing the diagnosis of Lynch syndrome is challenging, and ancillary studies that distinguish between sporadic DNA mismatch repair (MMR) protein deficiency and Lynch syndrome are needed, particularly when germline mutation studies are inconclusive. The aim of this study was to determine if MMR protein-deficient non-neoplastic intestinal crypts can help distinguish between patients with and without Lynch syndrome. We evaluated the expression of MMR proteins in non-neoplastic intestinal mucosa obtained from colorectal surgical resection specimens from patients with Lynch syndrome-associated colorectal carcinoma (n = 52) and patients with colorectal carcinoma without evidence of Lynch syndrome (n = 70), including sporadic MMR protein-deficient colorectal carcinoma (n = 30), MMR protein proficient colorectal carcinoma (n = 30), and "Lynch-like" syndrome (n = 10). MMR protein-deficient non-neoplastic colonic crypts were identified in 19 of 122 (16%) patients. MMR protein-deficient colonic crypts were identified in 18 of 52 (35%) patients with Lynch syndrome compared to only 1 of 70 (1%) patients without Lynch syndrome (p Lynch-like" syndrome and harbored two MSH2-deficient non-neoplastic colonic crypts. MMR protein-deficient non-neoplastic colonic crypts were not identified in patients with sporadic MMR protein-deficient or MMR protein proficient colorectal carcinoma. Our findings suggest that MMR protein-deficient colonic crypts are a novel indicator of Lynch syndrome, and evaluation for MMR protein-deficient crypts may be a helpful addition to Lynch syndrome diagnostics.

    Full Text Available Gitelman syndrome is a rare autosomal recessive hereditary salt-losing tubulopathy, that manifests as hypokalemic metabolic alkalosis, hypomagnesemia, and hypocalciuria. It is caused by mutations in the solute carrier family 12(sodium/chloride transporters, member 3 (SLC12A3 gene encoding the thiazide-sensitive sodium chloride cotransporter channel (NCCT in the distal convoluted tubule of the kidney. It is associated with muscle weakness, cramps, tetany, vomiting, diarrhea, abdominal pain, and growth retardation. The incidence of growth retardation, the exact cause of which is unknown, is lower than that of Bartter syndrome. Herein, we discuss the case of an overweight 12.9-year-old girl of short stature presenting with hypokalemic metabolic alkalosis. The patient, on the basis of detection of a heterozygous mutation in the SLC12A3 gene and poor growth hormone (GH responses in two provocative tests, was diagnosed with Gitelman syndrome combined with complete GH deficiency. GH treatment accompanied by magnesium oxide and potassium replacement was associated with a good clinical response.

    Wolfram syndrome 1 (WS) is a rare neurodegenerative disease that is caused by mutations in the Wolfram syndrome 1 (WFS1) gene, which encodes the endoplasmic reticulum (ER) glycoprotein wolframin. The pathophysiology of WS is ER stress, which is generally considered to induce oxidative stress. As WS has a well‑defined monogenetic origin and a model for chronic ER stress, the present study aimed to characterize how glutathione (GSH), a major intracellular antioxidant, was related to the disease and its progression. The concentration of GSH and the activities of reduction/oxidation system enzymes GSH peroxidase and GSH reductase were measured in Wfs1‑deficient mice. The GSH content was lower in most of the studied tissues, and the activities of antioxidative enzymes varied between the heart, kidneys and liver tissues. The results indicated that GSH may be needed for ER stress control; however, chronic ER stress from the genetic syndrome eventually depletes the cellular GSH pool and leads to increased oxidative stress.

    Changes in the plasma and urine levels of the trace metal zinc have been followed in a series of 37 adult patients totally supported by intravenous alimentation. Copper has also been determined in more recent cases. In such a seriously ill group, although urinary zinc loss may be very high at the height of catabolism, severe plasma depletion does not occur unless there is a subsequent phase of sustained anabolism and weight gain. In four patients plasma zinc fell to very low levels during this phase and three of this group developed a syndrome characterized by diarrhea, mental depression, para-nasal, oral and peri-oral dermatitis, and alopecia. The response to oral or intravenous zinc therapy is striking, except for hair regrowth which is delayed but eventually complete. The syndrome we have recognized in adult man has not been previously described. It resembles however the parakeratosis of zinc deficient swine and it is also very similar to Acrodermatitis enteropathica, a genetically determined disorder of infants very recently linked to zinc deficiency. Zinc is clearly essential to human metabolism and it should be included in all parenteral alimentation regimes particularly during the period of rapid, sustained, weight gain. Images Fig. 1. Fig. 2.

    To study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites. Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (Pmetabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

    Objectives To determine the prevalence of vitamin D deficiency and identify the relation between 25-hydroxyvitamin D [25(OH)D] levels and the consumption of dietary sources of vitamin D or exposure to anticonvulsants in females with Rett syndrome (RTT). Study design Retrospective review of the medical records of 284 females with RTT to determine serum 25(OH)D and parathyroid hormone levels, nutritional status, dietary sources of vitamin D, exposure to anticonvulsants, degree of mobility, and MECP2 status. Results Twenty percent of females who were tested (n=157) had 25(OH)D levels Anticonvulsants were used by 57% and 39% ambulated independently. Median 25(OH)D levels were lower in individuals who did not receive multivitamin supplements (panticonvulsants, degree of mobility, and MECP2 status did not influence 25(OH)D levels. Conclusion Vitamin D deficiency is prevalent in females with RTT. The use of multivitamin supplements or commercial formulas is associated with improved vitamin D levels. Attention to vitamin D may enhance bone mineral deposition and reduce the frequency of bone fractures in these individuals. PMID:21637127

    Creatine deficiency may play a role in the neurobiology of autism and may represent a treatable cause of autism. The goal of the study was to ascertain the prevalence of creatine deficiency syndromes (CDSs) in children with autism spectrum disorder (ASD). In a prospective multicenter study, 443 children were investigated after a confirmed diagnosis of ASD. Random spot urine screening for creatine metabolites (creatine, guanidinoacetate, creatinine, and arginine) with liquid chromatography-tandem mass spectrometry and second-tier testing with high-performance liquid chromatography methodology was followed by recall testing in 24-hour urines and confirmatory testing by Sanger-based DNA sequencing of GAMT, GATM, and SLC6A8 genes. Additional diagnostic tests included plasma creatine metabolites and in vivo brain proton magnetic resonance spectroscopy. The creatine metabolites in spot urine in the autism group were compared with 128 healthy controls controlled for age. In 443 subjects with ASD investigated for CDS, we had 0 events (event: 0, 95% confidence interval 0-0.0068), therefore with 95% confidence the prevalence of CDS is creatine metabolites (P > .0125) in urine. Our study revealed a very low prevalence of CDS in children with nonsyndromic ASD and no obvious association between creatine metabolites and autism. Unlike our study population, we expect more frequent CDS among children with severe developmental delay, speech impairment, seizures, and movement disorders in addition to impairments in social communication, restricted interests, and repetitive behaviors.

    The objective of this study was to correlate the magnetic resonance (MR) images in patients with hormone deficiencies with the clinical data and the hormonal status. We studied 11 cases ef empty sella with different peripheral pituitary deficiencies. Hormone levels were determined according to standard laboratory methods. All the patients underwent MR imaging. The studies were carried out with a 1 Tesla superconducting magnet, using the cranial cavity for transmission and reception. Segittal and coronal T1-weighted spin-echo sequences (TR/TE: 600/15 ms), axial T2-weighted spin-echo sequences (TR/TE: 3,500/19/93 ms) and gadolinium-enhanced (=.2 cc/kg body weight) sagital and coronal T1-weighted spin-echo sequences (TR/TE: 600/15 ms) were employed. Six of the patients presented partial or total hypopituitarism associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH); there was one case of panhypopituitarism without SIADH and four cases of primary hypothyroidism, there of which were associated with pituitary deficiency, MR imaging revealed five cases of partially empty sella with residual pituitary gland on the sella floor and six cases in which the sella was completely empty. This study also identified six cases of normally situated neurohypophysis, another four in which the neurohypophysis could not be identified and one case of ectopic neurohypophysis. MR imaging is the technique of choice in the study of abnormal hypothalamic-pituitary activity. Empty and partially empty sella should be included among the frequent causes of hypopituitarism, although there is no clear relationship between the degree of adenohypophyseal insufficiency and the degree of atrophy of this system as viewed in MR images. In some cases, this entity may be the radiological sign of a phase in the development of an autoimmune inflammatory process involving the pituitary gland. (Author) 16 refs

    Specific antibody deficiency (SAD) is an immune deficiency which has been reported in adults and children with recurrent respiratory tract infections; however, the clinical features of SAD are not well described. This study evaluated formally the clinical syndrome of SAD, by comparing the clinical features of children with SAD and those of children with recurrent infection but normal immune function tests. SAD was defined as an adequate IgG antibody response to less than 50% of 12 pneumococcal serotypes tested following 23-valent unconjugated pneumococcal immunization. An adequate IgG antibody response was defined as a post-immunization titre of >or= 1.3 microg/ml or >or= four times the preimmunization value. Seventy-four children with recurrent infection were evaluated where immune deficiencies other than SAD had been excluded. Eleven (14.9%) of these children had SAD. Clinical features differed between the group with SAD and the group with normal antibody responses. A history of otitis media, particularly in association with chronic otorrhoea was associated with SAD [relative risk (RR) of SAD in those with chronic otorrhoea 4.64 (P = 0.02)]. SAD was associated with allergic disease, particularly allergic rhinitis [RR of SAD in those with allergic rhinitis 3.77 (P = 0.04)]. These two clinical associations of SAD were independent in this study [RR of chronic otorrhoea in those with allergic rhinitis 0.85 (P = 0.28)]. SAD was not an age-related phenomenon in this population. SAD has a distinct clinical phenotype, presenting as recurrent infection associated with chronic otorrhoea and/or allergic disease, and the condition should be sought in children with these features.

    In recent years, metabolic syndrome, obesity, diabetes and cardiovascular disease has had a tremendous elevation growth. Many studies have demonstrated negative correlation between vitamin D deficiency and indexes of metabolic syndrome in obese patients. This study was designed to find the relation between vitamin D deficiency and markers of metabolic syndrome among overweight and obese adults referred to obesity center of Shahid Sadoughi hospital in 2014. Eighty-nine overweight and obese adults (79 women and 10 men), who 13 subjects were overweight and 76 subjects were obese were recruited in this cross-sectional study. Total cholesterol, high-density lipoprotein cholesterol, triglyceride, plasma glucose and vitamin D were measured. IDF criteria were used for identifying subjects with metabolic syndrome. Demographic questionnaire was completed. Statistical analysis was performed using SPSS version 16.0. Fisher exact test, logistic regression, and Spearman correlation coefficient were used. The frequency of vitamin D deficiency was 93.2%. According to IDF criteria, the frequency of metabolic syndrome was 36%. There was no significant relationship between vitamin D deficiency and metabolic syndrome. Among metabolic syndrome indicators, there was a significant direct relationship between vitamin D level with FBS (P=0.013) and SBP (P=0.023). There was no significant relationship between vitamin D deficiency and metabolic syndrome. Due to the lack of relationship between vitamin D deficiency and metabolic syndrome, small number of participants in this study and very low case of normal vitamin D level, further studies are needed.

    Full Text Available In the general-somatic network there is a steady increase in the number of patients with psychosomatic disorders. Problems of providing adequate psychiatric and psychotherapeutic assistance to this category of patients are related to the motivation of patients to participate in psychological measures and the readiness of the medical system to provide comprehensive care on the basis of the biopsychosocial approach. Mental factors are involved both in the occurrence and course of a metabolic syndrome in the form of a patient's lifestyle and behavior patterns of healthy functioning, and is a consequence of somatic pathology. Mental factors are involved both in the occurrence and course of a metabolic syndrome in the form of a patient's lifestyle and behavior patterns of healthy functioning, and is a consequence of somatic pathology. So mental disorders of metabolic syndrome are manifested in the form of psychosocial maladaptation, neurotic, affective, personality, and organic disorders. Desynchronosis which is a factor of the development of a metabolic syndrome and characterizes the complex chronobiological component of the regulation of psychophysiological functions in norm and under the influence of stress, deserves special attention. Addressing the diagnosis of mental disorders associated with metabolic syndrome is precisely aimed at determining chronobiological disorders of psychosomatic integrated areas and is supposed to improve diagnostic and treatment process and to shorten the treatment of these disorders.

    Full Text Available Abstract Background Vitamin D deficiency is a re-emerging epidemic, especially in minority populations. Vitamin D is crucial not only for bone health but for proper brain development and functioning. Low levels of vitamin D are associated with depression, seasonal affective disorder, and schizophrenia in adults, but little is known about vitamin D and mental health in the pediatric population. Methods One hundred four adolescents presenting for acute mental health treatment over a 16-month period were assessed for vitamin D status and the relationship of 25-OH vitamin D levels to severity of illness, defined by presence of psychotic features. Results Vitamin D deficiency (25-OH D levels Conclusions Vitamin D deficiency and insufficiency are both highly prevalent in adolescents with severe mental illness. The preliminary associations between vitamin D deficiency and presence of psychotic features warrant further investigation as to whether vitamin D deficiency is a mediator of illness severity, result of illness severity, or both. Higher prevalence of vitamin D deficiency but no greater risk of psychosis in African Americans, if confirmed, may have special implications for health disparity and treatment outcome research.

    To evaluate the relationship between androgen levels and subjective and objective measures of dry eye syndrome (DES). A total of 263 male patients from the Miami Veterans Affairs Medical Center eye clinic aged ≥50 were recruited for this prospective cross-sectional study. Patients completed Dry Eye Questionnaire 5, underwent tear film evaluation, and had serum androgen levels measured. The correlations between androgen levels, DES composite scores, DES symptoms, and global, lipid, and aqueous tear film parameters were evaluated. Two hundred sixty-three patients with a mean age of 69 (50-95) were examined. There was no linear association between composite DES scores (generated using latent class analysis) and androgen levels. However, eyes with high DES scores (0.95-1.0) had higher levels of sex hormone-binding globulin (P = 0.03) and lower levels of dehydroepiandrosterone sulfate (DHEAS) (P = 0.02), androstenedione (A) (P = 0.02), and androstane-3α,17β-diol glucuronide (P = 0.03) compared to eyes with intermediate (0.05-0.95) or low (0-0.05) scores. There were no strong correlations between tear film measures and androgen levels. Regarding global parameters, a weak inverse correlation was found between corneal staining and A (r = -0.17, P = 0.009). For lipid parameters, a weak correlation existed between tear breakup time (TBUT) and A (r = 0.15, P = 0.02). When considering aqueous and lipid deficiency independently, the association between TBUT and A existed only with aqueous tear deficiency (r = 0.66, P = 0.002).

    Full Text Available Obesity and many well described eating disorders are accurately considered a global epidemic. The consequences of Reward Deficiency Syndrome, a genetic and epigenetic phenomena that involves the interactions of powerful neurotransmitters, are impairments of brain reward circuitry, hypodopaminergic function and abnormal craving behavior. Numerous sound neurochemical and genetic studies provide strong evidence that food addiction is similar to psychoactive drug addiction. Important facts which could translate to potential therapeutic targets espoused in this review include: 1 brain dopamine (DA production and use is stimulated by consumption of alcohol in large quantities or carbohydrates bingeing; 2 in the mesolimbic system the enkephalinergic neurons are in close proximity, to glucose receptors; 3 highly concentrated glucose activates the calcium channel to stimulate dopamine release from P12 cells; 4 blood glucose and cerebrospinal fluid concentrations of homovanillic acid, the dopamine metabolite, are significantly correlated and 5 2-deoxyglucose the glucose analogue, in pharmacological doses associates with enhanced dopamine turnover and causes acute glucoprivation. Evidence from animal studies and human fMRI support the hypothesis that multiple, but similar brain circuits are disrupted in obesity and drug dependence and DA-modulated reward circuits are involved in pathologic eating behaviors. Treatment for addiction to glucose and drugs alike, based on a consensus of neuroscience research, should incorporate dopamine agonist therapy, in contrast to current theories and practices that use dopamine antagonists. Until now, powerful dopamine-D2 agonists have failed clinically, due to chronic down regulation of D2 receptors instead, consideration of novel less powerful D2 agonists that up-regulate D2 receptors seems prudent. We encourage new strategies targeted at improving DA function in the treatment and prevention of obesity a subtype of

    Lynch syndrome is a cancer predisposition syndrome caused by germline mutations in mismatch repair (MMR) genes. MMR deficiency is a ubiquitous feature of Lynch syndrome-associated colorectal adenocarcinomas; however, it remains unclear when the MMR-deficient phenotype is acquired during tumorigenesis. To probe this issue, the present study examined genetic alterations and MMR statuses in Lynch syndrome-associated colorectal adenomas and adenocarcinomas, in comparison with sporadic adenomas. Among the Lynch syndrome-associated colorectal tumors, 68 of 86 adenomas (79%) and all adenocarcinomas were MMR-deficient, whereas all the sporadic adenomas were MMR-proficient, as determined by microsatellite instability testing and immunohistochemistry for MMR proteins. Sequencing analyses identified APC or CTNNB1 mutations in the majority of sporadic adenomas (58/84, 69%) and MMR-proficient Lynch syndrome-associated adenomas (13/18, 72%). However, MMR-deficient Lynch syndrome-associated adenomas had less APC or CTNNB1 mutations (25/68, 37%) and frequent frameshift RNF43 mutations involving mononucleotide repeats (45/68, 66%). Furthermore, frameshift mutations affecting repeat sequences constituted 14 of 26 APC mutations (54%) in MMR-deficient adenomas whereas these frameshift mutations were rare in MMR-proficient adenomas in patients with Lynch syndrome (1/12, 8%) and in sporadic adenomas (3/52, 6%). Lynch syndrome-associated adenocarcinomas exhibited mutation profiles similar to those of MMR-deficient adenomas. Considering that WNT pathway activation sufficiently drives colorectal adenoma formation, the distinct mutation profiles of WNT pathway genes in Lynch syndrome-associated adenomas suggest that MMR deficiency commonly precedes adenoma formation.

    Full Text Available Artemis, DNA ligase IV, DNA protein kinase catalytic subunit, and Cernunnos/XLF genes in nonhomologous end joining pathways of DNA repair mechanisms have been identified as responsible for radiosensitive SCID. Here, we present a 3-year-old girl patient with severe growth retardation, bird-like face, recurrent perianal abscess, pancytopenia, and polydactyly. Firstly, she was thought as Fanconi anemia and spontaneous DNA breaks were seen on chromosomal analysis. After that DEB test was found to be normal and Fanconi anemia was excluded. Because of that she had low IgG and IgA levels, normal IgM level, and absence of B cells in peripheral blood; she was considered as primary immunodeficiency, Nijmegen breakage syndrome. A mutation in NBS1 gene was not found; then Cernunnos/XLF deficiency was investigated due to clinical similarities with previously reported cases. Homozygous mutation in Cernunnos/XLF gene (NHEJ1 was identified. She is now on regular IVIG prophylaxis and has no new infection. Fully matched donor screening is in progress for bone marrow transplantation which is curative treatment of the disease. In conclusion, the patients with microcephaly, bird-like face, and severe growth retardation should be evaluated for hypogammaglobulinemia and primary immunodeficiency diseases.

    Full Text Available India has a large number of patients with acquired immune deficiency syndrome (AIDS, the third largest population of this group in the world. This disease was first described in patients with Pneumocystis pneumonia in 1981. Ocular lesions can occur at any stage of the disease but are more commonly seen at the late stages. Human immunodeficiency virus (HIV, the causative agent of AIDS is a retrovirus with RNA genome and a unique ′Reverse transcriptase enzyme′ and is of two types, HIV-1 and 2. Most human diseases are caused by HIV-1. The HIV-1 subtypes prevalent in India are A, B and C. They act predominantly by reducing the CD4+ cells and thus the patient becomes susceptible to opportunistic infections. High viral titers in the peripheral blood during primary infection lead to decrease in the number of CD4+ T lymphocytes. Onset of HIV-1-specific cellular immune response with synthesis of HIV-1 specific antibodies leads to the decline of plasma viral load and chronification of HIV-1 infection. However, the asymptomatic stage of infection may lead to persistent viral replication and a rapid turnover of plasma virions which is the clinical latency. During this period, there is further decrease in the CD4+ counts which makes the patient′s immune system incapable of controlling opportunistic pathogens and thus life-threatening AIDS-defining diseases emerge. Advent of highly active antiretroviral treatment (HAART has revolutionized the management of AIDS though there is associated increased development of immune recovery uveitis in a few of these patients.

    Growth hormone deficiency affects roughly between one in 3000 and one in 4000 children with most instances of growth hormone deficiency being idiopathic. Growth hormone deficiency can also be associated with genetic diseases or chromosome abnormalities. Association of growth hormone deficiency together with hypothalamic-pituitary axis malformation and Cat-Eye syndrome is a very rare condition. We report a family with two brothers presenting with growth delay due to a growth hormone deficiency associated with a polymalformation syndrome. They both displayed pre-auricular pits and tags, imperforate anus and Duane retraction syndrome. Both parents and a third unaffected son displayed normal growth pattern. Cerebral MRI showed a hypothalamic-pituitary axis malformation in the two affected brothers. Cytogenetic studies revealed a type I small supernumerary marker chromosome derived from chromosome 22 resulting in a tetrasomy 22pter-22q11.21 characteristic of the Cat-Eye syndrome. The small supernumerary marker chromosome was present in the two affected sons and the mother in a mosaic state. Patients with short stature due to growth hormone deficiency should be evaluated for chromosomal abnormality. Family study should not be underestimated. Copyright © 2015 Elsevier Masson SAS.

  10. Reward deficiency syndrome: genetic aspects of behavioral disorders.

    The dopaminergic and opioidergic reward pathways of the brain are critical for survival since they provide the pleasure drives for eating, love and reproduction; these are called 'natural rewards' and involve the release of dopamine in the nucleus accumbens and frontal lobes. However, the same release of dopamine and production of sensations of pleasure can be produced by 'unnatural rewards' such as alcohol, cocaine, methamphetamine, heroin, nicotine, marijuana, and other drugs, and by compulsive activities such as gambling, eating, and sex, and by risk taking behaviors. Since only a minority of individuals become addicted to these compounds or behaviors, it is reasonable to ask what factors distinguish those who do become addicted from those who do not. It has usually been assumed that these behaviors are entirely voluntary and that environmental factors play the major role; however, since all of these behaviors have a significant genetic component, the presence of one or more variant genes presumably act as risk factors for these behaviors. Since the primary neurotransmitter of the reward pathway is dopamine, genes for dopamine synthesis, degradation, receptors, and transporters are reasonable candidates. However, serotonin, norepinephrine, GABA, opioid, and cannabinoid neurons all modify dopamine metabolism and dopamine neurons. We have proposed that defects in various combinations of the genes for these neurotransmitters result in a Reward Deficiency Syndrome (RDS) and that such individuals are at risk for abuse of the unnatural rewards. Because of its importance, the gene for the [figure: see text] dopamine D2 receptor was a major candidate gene. Studies in the past decade have shown that in various subject groups the Taq I A1 allele of the DRD2 gene is associated with alcoholism, drug abuse, smoking, obesity, compulsive gambling, and several personality traits. A range of other dopamine, opioid, cannabinoid, norepinephrine, and related genes have since been

    Refeeding syndrome can occur in several contexts of relative malnutrition in which an overaggressive nutritional support is started. The consequences are life threatening with multiorgan impairment, and severe electrolyte imbalances. During refeeding, glucose-involved insulin secretion causes abrupt reverse of lipolysis and a switch from catabolism to anabolism. This creates a sudden cellular demand for electrolytes (phosphate, potassium, and magnesium) necessary for synthesis of adenosine triphosphate, glucose transport, and other synthesis reactions, resulting in decreased serum levels. Laboratory findings and multiorgan impairment similar to refeeding syndrome also are observed in acute thiamine deficiency. The aim of this study was to determine whether thiamine deficiency was responsible for the electrolyte imbalance caused by tubular electrolyte losses. We describe two patients with leukemia who developed acute thiamine deficiency with an electrolyte pattern suggestive of refeeding syndrome, severe lactic acidosis, and evidence of proximal renal tubular dysfunction. A single thiamine administration led to rapid resolution of the tubular dysfunction and normalization of acidosis and electrolyte imbalance. This demonstrated that thiamine deficiency was responsible for the electrolyte imbalance, caused by tubular electrolyte losses. Our study indicates that, despite sharing many laboratory similarities, refeeding syndrome and acute thiamine deficiency should be viewed as separate entities in which the electrolyte abnormalities reported in cases of refeeding syndrome with thiamine deficiency and refractory lactic acidosis may be due to renal tubular losses instead of a shifting from extracellular to intracellular compartments. In oncologic and malnourished patients, individuals at particular risk for developing refeeding syndrome, in the presence of these biochemical abnormalities, acute thiamine deficiency should be suspected and treated because it promptly

    Cornelia de Lange syndrome is a genetic disease characterized by distinctive facial features, failure to thrive, microcephaly and several malformations associated. Its main endocrinological features are anomalies of the genitalia. We present a 13-year-old boy, who suffered from complicated aspiration pneumonia and showed Cornelia de Lange syndrome phenotype, with global developmental delay, suction-swallowing abnormalities, short stature and abnormal genitalia associated. His bone age was delayed, so he underwent full endocrinological panel. Central hypothyroidism, growth hormone deficiency and low luteinizing hormone-follicle-stimulating hormone levels were observed and multiple pituitary hormone deficiencies diagnosis was made. Basal cortisol, adrenocorticotropic hormone and prolactin levels were normal. He received thyroid hormonal substitution. Multiple pituitary hormone deficiencies are an unusual feature of De Lange syndrome. We suggest evaluating all different endocrine axes in these patients. Sociedad Argentina de Pediatría.

    Classic Bartter syndrome is a salt-wasting tubulopathy caused by mutations in the CLCNKB (chloride channel Kb) gene. Although growth hormone deficiency has been suggested as a cause for persistent growth failure in patients with classic Bartter syndrome, in our opinion the diagnoses of growth hormone deficiency has been unconvincing in some reports. Moreover, Gitelman syndrome seems to have been confused with Bartter syndrome in some cases in the literature. In the present work, we describe a new case with CLCNKB gene mutations and review the reported cases of classic Bartter syndrome associated with growth hormone deficiency. Our patient was a Japanese boy diagnosed as having classic Bartter syndrome at eight months of age. The diagnosis of Bartter syndrome was confirmed by CLCNKB gene analysis, which revealed compound heterozygous mutations with deletion of exons 1 to 3 (derived from his mother) and ΔL130 (derived from his father). His medical therapy consisted of potassium (K), sodium chloride, spironolactone, and anti-inflammatory agents; this regime was started at eight months of age. Our patient was very short (131.1cm, -4.9 standard deviation) at 14.3 years and showed profoundly impaired growth hormone responses to pharmacological stimulants: 0.15μg/L to insulin-induced hypoglycemia and 0.39μg/L to arginine. His growth response to growth hormone therapy was excellent. The present case strengthens the association between classic Bartter syndrome and growth hormone deficiency. We propose that growth hormone status should be considered while treating children with classic Bartter syndrome.

    Common Variable Immuno-Deficiency (CVID) is the most common symptomatic primary antibody-deficiency syndrome, but the basic immunologic defects underlying this syndrome are not well defined. We report here that among eight patients studied (six CVID and two hypogammaglobulinemic patients with recurrent infections), there is in two CVID patients a dramatic reduction in Ig V gene somatic hypermutation with 40-75% of IgG transcripts totally devoid of mutations in the circulating memory B cell compartment. Functional assays of the T cell compartment point to an intrinsic B cell defect in the process of antibody affinity maturation in these two cases.

    Full Text Available The final most common pathway for the majority of coronary artery disease is occlusion of a coronary vessel. Under normal conditions, antithrombin III (AT III, protein C, and protein S as an active protein C cofactor, are natural anticoagulants (hemostatic control that balances procoagulant activity (thrombin antithrombin complex balance to prevent thrombosis. If the condition becomes unbalanced, natural anticoagulants and the procoagulants can lead to thrombosis. Thirty subjects with acute coronary syndrome (ACS were studied for the incidence of antithrombin III (AT III, protein C, and protein S deficiencies, and the result were compare to the control group. Among patients with ACS, the frequency of distribution of AT-III with activity < 75% were 23,3% (7 of 30, and only 6,7% ( 2 of 30 in control subject. No one of the 30 control subject have protein C activity deficient, in ACS with activity < 70% were 13,3% (4 of 30. Fifteen out of the 30 (50% control subjects had protein S activity deficiency, while protein S deficiency activity < 70% was found 73.3.% (22 out of 30. On linear regression, the deterministic coefficient of AT-III activity deficiency to the development ACS was 13,25 %, and the deterministic coefficient of protein C activity deficient to the development of ACS was 9,06 %. The cut-off point for AT-III without protein S deficiency expected to contribute to the development of vessel disease was 45%. On discriminant analysis, protein C activity deficiency posed a risk for ACS of 4,5 greater than non deficient subjects, and AT-III activity deficiency posed a risk for ACS of 3,5 times greater than non deficient subjects. On binary logistic regression, protein S activity acted only as a reinforcing factor of AT-III activity deficiency in the development of ACS. Protein C and AT III deficiency can trigger ACS, with determinant coefficients of 9,06% and 13,25% respectively. Low levels of protein C posed a greater risk of

    Constitutional mismatch repair-deficiency (CMMR-D) syndrome is an autosomal recessive condition characterized by hematologic malignancies, brain tumors, Lynch syndrome-associated cancers and skin manifestations reminiscent of neurofibromatosis type 1 (NF1). In contrast to Lynch syndrome, CMMR-D syndrome is exceptionally rare, onset typically occurs in infancy or early childhood and, as described in this report, may also present with colonic polyposis suggestive of attenuated familial adenomatous polyposis (AFAP) or MUTYH associated polyposis (MAP). Here we describe two sisters with CMMR-D syndrome due to germline bi-allelic MSH6 mutations. Both sisters are without cancer, are older than typical for this condition, have NF1 associated features and a colonic phenotype suspicious for an attenuated polyposis syndrome. This report highlights the role of skin examinations in leading to an underlying genetic diagnosis in individuals with colonic adenomatous polyposis, but without mutations associated with AFAP or MAP. © 2010 John Wiley & Sons A/S.

    Full Text Available Traditional Chinese medicine (TCM syndrome is an important basis for TCM diagnosis and treatment. As Child-Pugh classification as well as compensation and decompensation phase in liver cirrhosis, it is also an underlying clinical classification. In this paper, we investigated the correlation between single nucleotide polymorphisms (SNPs of Interleukin-10 (IL-10 and TCM syndromes in patients with hepatitis B cirrhosis (HBC. Samples were obtained from 343 HBC patients in China. Three SNPs of IL-10 (−592A/C, −819C/T, and −1082A/G were detected with polymerase chain-reaction-ligase detection reaction (PCR-LDR. The result showed the SNP-819C/T was significantly correlated with Deficiency syndrome (P=0.031, but none of the 3 loci showed correlation either with Child-Pugh classification and phase in HBC patients. The logistic regression analysis showed that the Excess syndrome was associated with dizzy and spider nevus, and the Deficiency syndrome was associated with dry eyes, aversion to cold, IL-10-819C/T loci, and IL-10-1082A/G loci. The odds ratio (OR value at IL-10-819C/T was 4.022. The research results suggested that IL-10-819C/T locus (TC plus CC genotype is probably a risk factor in the occurrence of Deficiency syndrome in HBC patients.

    Zinc deficiency-like (ZDL) syndrome is an inherited defect of Fleckvieh calves, with striking similarity to bovine hereditary zinc deficiency (BHZD). However, the causative mutation in a phospholipase D4 encoding gene (PLD4) shows no connection to zinc metabolism. To describe clinical signs, laboratory variables, and pathological findings of ZDL syndrome and their utility to differentiate ZDL from BHZD and infectious diseases with similar phenotype. Nine hospitalized calves with crusting dermatitis and confirmed mutation in PLD4 and medical records from 25 calves with crusting dermatitis or suspected zinc deficiency. Prospective and retrospective case series. The 9 calves (age: 5-53 weeks) displayed a moderate to severe crusting dermatitis mainly on the head, ventrum, and joints. Respiratory and digestive tract inflammations were frequently observed. Zinc supplementation did not lead to remission of clinical signs in 4 calves. Laboratory variables revealed slight anemia in 8 calves, hypoalbuminemia in 6 calves, but reduced serum zinc concentrations in only 3 calves. Mucosal erosions/ulcerations were present in 7 calves and thymus atrophy or reduced thymic weights in 8 calves. Histologically, skin lesions were indistinguishable from BHZD. Retrospective analysis of medical records revealed the presence of this phenotype since 1988 and pedigree analysis revealed a common ancestor of several affected calves. ZDL syndrome should be suspected in Fleckvieh calves with crusting dermatitis together with diarrhea or respiratory tract inflammations without response to oral zinc supplementation. Definite diagnosis requires molecular genetic confirmation of the PLD4 mutation. Copyright © 2018 The Authors.

    Nance-Horan syndrome (NHS) is a rare X-linked condition comprising congenital cataract with microcornea, distinctive dental, and evocative facial anomalies. Intellectual handicap was mentioned in seven published NHS patients. We performed a clinical study focused on psychomotor development, intellectual abilities, and behavior in 13 affected males in four NHS families, and present the results of a neuropsychological evaluation in 7 of them. Our study confirms that mental retardation (MR) can be a major component of the NHS. Combining our data with those from the literature leads to a frequency of MR in NHS of around 30%. In most cases, MR is mild or moderate (80%) and not associated with motor delay. Conversely, a profound mental handicap associated with autistic traits may be observed. MR has intra- and inter-familial variability but does not appear to be expressed in carriers. Awareness of MR in NHS may be of importance in the management of the patients, especially in terms of education. Cloning and characterization of the gene and analysis of mutations will be an important step towards understanding the molecular basis of mental deficiency in NHS, and in delineation from the other XLMR conditions at Xp22.

    Wolfram syndrome is a rare autosomal recessive genetic disease characterized by insulin dependent diabetes and vision, hearing and brain abnormalities which generally emerge in childhood. Mutations in the WFS1 gene predispose cells to endoplasmic reticulum stress-mediated apoptosis and may induce myelin degradation in neuronal cell models. However, in vivo evidence of this phenomenon in humans is lacking. White matter microstructure and regional volumes were measured using magnetic resonance imaging in children and young adults with Wolfram syndrome (n = 21) and healthy and diabetic controls (n = 50). Wolfram patients had lower fractional anisotropy and higher radial diffusivity in major white matter tracts and lower volume in the basilar (ventral) pons, cerebellar white matter and visual cortex. Correlations were found between key brain findings and overall neurological symptoms. This pattern of findings suggests that reduction in myelin is a primary neuropathological feature of Wolfram syndrome. Endoplasmic reticulum stress-related dysfunction in Wolfram syndrome may interact with the development of myelin or promote degeneration of myelin during the progression of the disease. These measures may provide objective indices of Wolfram syndrome pathophysiology that will be useful in unraveling the underlying mechanisms and in testing the impact of treatments on the brain.

    Full Text Available Kearns-Sayre syndrome is characterized by onset before 20 years, chronic progressive external opthalmoplegia, pigmentary retinal degeneration, and ataxia (and/or hearth block, and/or high protein content in the cerebrospinal fluid in the presence of mtDNA rearrangements. Multiple endocrine dysfunction associated with this syndrome was rarely reported. In this paper, the Authors report on a female patient with Kearns-Sayre syndrome with large heteroplasmic mtDNA deletion, absence of cytochrome c oxidase in many muscle fibers, partial GH deficiency, hypothyroidism and subsequently insulin dependent diabetes mellitus (IDDM. Anti-thyroid peroxidase and antithyreoglobulin antibodies were present in high titer in serum while anti-islet cell antibodies were absent. The patient developed thyroiditis with Hashimoto encephalopathy. The presence of GH deficiency, autoimmune thyroiditis with hypothyroidism and IDDM distinguishes this case from others and confirms the association of Kearns-Sayre syndrome with multiple endocrine dysfunction. Hashimoto encephalopathy and anti-thyroideal antibodies suggest that in this patient, predisposed by a genetic factor (a mitochondrial deletion anti-thyroideal antibodies may have contributed to the hypothyroidism and, by interfering with cerebral mitochondrial function, may have caused the encephalopathy. GH deficiency and IDDM can be attributed to oxidative phosphorylation deficiency but the autoimmunity may also have played a role in the production of glandular insufficiencies. It seems important to search for endocrine autoimmunity in every case of KSS.

    Sinus node dysfunction (SND) is a major clinically relevant disease that is associated with sudden cardiac death and requires surgical implantation of electric pacemaker devices. Frequently, SND occurs in heart failure and hypertension, conditions that lead to electric instability of the heart. Although the pathologies of acquired SND have been studied extensively, little is known about the molecular and cellular mechanisms that cause congenital SND. Here, we show that the HCN1 protein is highly expressed in the sinoatrial node and is colocalized with HCN4, the main sinoatrial pacemaker channel isoform. To characterize the cardiac phenotype of HCN1-deficient mice, a detailed functional characterization of pacemaker mechanisms in single isolated sinoatrial node cells, explanted beating sinoatrial node preparation, telemetric in vivo electrocardiography, echocardiography, and in vivo electrophysiology was performed. On the basis of these experiments we demonstrate that mice lacking the pacemaker channel HCN1 display congenital SND characterized by bradycardia, sinus dysrhythmia, prolonged sinoatrial node recovery time, increased sinoatrial conduction time, and recurrent sinus pauses. As a consequence of SND, HCN1-deficient mice display a severely reduced cardiac output. We propose that HCN1 stabilizes the leading pacemaker region within the sinoatrial node and hence is crucial for stable heart rate and regular beat-to-beat variation. Furthermore, we suggest that HCN1-deficient mice may be a valuable genetic disease model for human SND.

    The so-called «testosterone deficiency syndrome» is a blend of nonspecific symptoms typical of the physiological process of aging. This syndrome has been the subject of intense promotional activity that has presented the phenomenon as highly prevalent and with a major public health impact. This strategy has been accompanied by the emergence of new and easy to administer testosterone devices into the pharmaceutical market and has generated significant sales for drug companies. The commercial promotion of testosterone deficiency syndrome and its remedies has exploited cultural stereotypes of aging and sexuality through awareness campaigns promoted by the laboratories involved and has been disseminated by media with the participation of numerous experts and with the support of scientific associations, representing a paradigmatic case of disease mongering. This example might be of use in the response to disease mongering activities from the clinical and public health fields. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

    2016-01-01

    Full Text Available We describe a 4-year-old female child with a dysmorphic and neurological syndrome of trigonocephaly, mental and psychomotor retardation and dysmorphic facial features. The anomalies of the face were the following: slight upward palpebral fissures, ocular hypertelorism, depressed nasal bridge, hypoplastic nasal root, short nose with anteverted nares; small low set ears, smooth broad philtrum and thin upper lip. The patient had important cerebral anomalies with diffuse alterations in white matter that caused developmental delay with verbal and nonverbal disabilities and severe learning difficulties. This clinical presentation is compatible with the diagnosis of the Opitz C syndrome, a heterogeneous disease of multiple neurological and craniofacial abnormalities. The physical sign more detectable and notorious is the trigonocephaly that is manifested by a prominent metopic suture, but also can be distinguished the other minor facial anomalies that are found in the eyes, nose, mouth and ears that constitute the phenotype of the disorder. The neurological development was altered by the compression of the cerebral frontal lobes with narrowing of this cerebral area, producing hypotonia with muscle weakness, epileptic episodes manifested by seizures, and neurobehavioral and neurocognitive disorders. This syndrome is a very rare genetic disorder with autosomal recessive inheritance trait; our patient had no chromosomal abnormality in the usual karyotype but the fluorescence in situ hybridization (FISH technique showed a balanced translocation between the chromosomes two and eleven: t(2:11 (q32.2/q24.

    Full Text Available Abstract Background 2-methylbutyryl-CoA dehydrogenase deficiency or short/branched chain acyl-CoA dehydrogenase deficiency (SBCADD is caused by a defect in the degradation pathway of the amino acid L-isoleucine. Methods We report a four-year-old mentally retarded Somali boy with autism and a history of seizures, who was found to excrete increased amounts of 2-methylbutyryl glycine in the urine. The SBCAD gene was examined with sequence analysis. His development was assessed with psychometric testing before and after a trial with low protein diet. Results We found homozygosity for A > G changing the +3 position of intron 3 (c.303+3A > G in the SBCAD gene. Psychometric testing showed moderate mental retardation and behavioral scores within the autistic spectrum. No beneficial effect was detected after 5 months with a low protein diet. Conclusion This mutation was also found in two previously reported cases with SBCADD, both originating from Somalia and Eritrea, indicating that it is relatively prevalent in this population. Autism has not previously been described with mutations in this gene, thus expanding the clinical spectrum of SBCADD.

    Full Text Available Vitamin D is a fat-soluble vitamin which has an important role in bone metabolism with some anti-inflammatory and immune-modulating properties. It is very unique since it can be made in the skin from exposure to sunlight. Cardiometabolic syndrome (CMS is a group of metabolic abnormalities that can increase the risk of cardiovascular disease and type 2 diabetes. It develops in an individual with any three of the following risk factors including obesity, diabetes, hypertension, dyslipidemia, and thrombosis. Both dietary and environmental factors, when combined with a sedentary lifestyle, lead to metabolic syndrome (MS risk factors. The research outcomes propose to increase the current Vitamin D fortification level in foods to reduce the risk factors of the MS. Further researches are needed before clinical practice can recommend a Vitamin D prescription as a treatment for CMS in the general population.

    Although cobalamin (cbl) C deficiency is the most common inherited disorder of vitamin B12 metabolism, the late-onset form of the disease can be difficult to recognize because it has a broad phenotypic spectrum. In this report, we describe an adolescent female exposed to unknown illicit substances and sexual abuse who presented with psychosis, anorexia, seizures, and ataxia. The patient's diagnosis was delayed until a metabolic workup was initiated, revealing hyperhomocysteinemia, low normal plasma methionine, and methylmalonic aciduria. Ultimately, cblC deficiency was confirmed when molecular testing showed compound heterozygosity for mutations (c.271dupA and c.482G>A) in the MMACHC gene. This diagnosis led to appropriate treatment with hydroxocobalamin, betaine, and folate, which resulted in improvement of her clinical symptoms and laboratory values. This patient demonstrates a previously unrecognized presentation of late-onset cblC deficiency. Although neuropsychiatric symptoms are common in late-onset disease, seizures and cerebellar involvement are not. Furthermore, anorexia has not been previously described in these patients. This case emphasizes that inborn errors of metabolism should be part of the differential diagnosis for a teenager presenting with altered mental status, especially when the diagnosis is challenging or neurologic symptoms are unexplained. Correct diagnosis of this condition is important because treatment is available and can result in clinical improvement.(1.) Copyright © 2014 by the American Academy of Pediatrics.

    Previous studies have suggested an association between MS and vitamin D deficiency, but data are not conclusive. This study was intended to find out if metabolic syndrome, according to the 2009 IDF/AHA/NHLBI, is associated to the presence of vitamin D deficiency. A cross-sectional study was conducted on a sample of 326 subjects aged 18 years or older, recruited from a health center in Alcalá de Henares. Participants underwent an interview and a standardized clinical examination. In a second visit, blood tests were performed in 255 subjects to quantify serum levels of 25-hydroxyvitamin D (25 OH-VitD) and different laboratory parameters associated to MS. The association between vitamin D deficiency and metabolic syndrome (and each of its components) was examined. In the study population, MS prevalence was 36.1% and prevalence of vitamin D deficiency (25 OH-Vit D1.62 (95% CI: 1.13-2.31). Adjustment for age, sex, and body mass index did not change such association. There is a significant association between vitamin D deficiency and MS. Both conditions are highly prevalent in our population. Copyright © 2014 SEEN. Published by Elsevier España, S.L.U. All rights reserved.

    Bartter syndrome is a rare autosomal recessive, salt-losing disorder characterized by hypokalemic hypochloremic metabolic alkalosis. A 10-year-old boy had severe growth retardation (height standard deviation score -8.15). He had a thin, triangular face, prominent ears and forehead, and big eyes. Megacystis, bilateral hydroureteronephrosis, and residual urine were detected in ultrasonography, but there was no vesicoureteral reflux. Lumbosacral magnetic resonance (MR) showed posterior disc bulging at L4-5. Serum sodium and chloride levels were normal, but mild hypokalemia was overlooked initially. During follow-up, hypokalemic hypochloremic metabolic alkalosis developed, with high urinary chloride and potassium excretion (52 and 43 mEq/L, respectively). The patient, with renal salt loss, was thought to have classic Bartter syndrome due to absence of nephrocalcinosis, presence of persistent hypercalciuria and sensorineural deafness, and presence of relatively mild clinical and laboratory findings, except polyuria initially. The child was treated with indomethacin, spironolactone, and oral potassium in addition to growth hormone (GH). During treatment, he had considerable increase in weight and height compared with the period of GH therapy only. We present this case because, although growth retardation is a major feature of Bartter syndrome, associated GH deficiency is rarely reported in the literature. Diagnosis of Bartter syndrome was made later, as our patient was followed for megacystis and megaureter secondary to the neurogenic bladder and GH deficiency initially; and proteinuria associated with focal segmental glomerulosclerosis responded to treatment for Bartter syndrome.

    Median arcuate ligament syndrome is an anatomic and clinical entity characterized by dynamic compression of the proximal celiac artery by the median arcuate ligament, which leads to postprandial epigastric pain, vomiting, and weight loss. These symptoms are usually nonspecific and are easily misdiagnosed as functional dyspepsia, peptic ulcer disease, or gastropathy. In this report, we presented a 72-year-old male patient with celiac artery compression syndrome causing recurrent abdominal pain associated with gastric ulcer and iron deficiency anemia. This association is relatively uncommon and therefore not well determined. In addition, we reported the CT angiography findings and three-dimensional reconstructions of this rare case.

    A case with GAMT deficiency (homozygous c.64dupG mutation) presented with neurodevelopmental delay, rare seizures, behavioral disturbances, and mild hypotonia, posing diagnostic challenges. Metabolic investigations showed low creatinine in plasma and urine (guanidinoacetate couldn't be investigated) and slightly elevated lactate. MRI was normal. Correct diagnosis was possible only after MR spectroscopy was performed at age 5½ years. A homozygous c.64dupG mutation of the GAMT gene was identified in the proband. In conclusion, every case with neurodevelopmental delay or arrest, especially when accompanied by seizures, behavioral impairment, muscle hypotonia or extrapyramidal symptoms should undergo MRI with MR spectroscopy. Normal structural MRI doesn't exclude a creatine deficiency syndrome. Biochemical investigations of guanidinoacetate, creatine, and creatinine in body fluid should be done to diagnose cerebral creatine deficiency syndromes and to specify the deficient enzyme. Thus, a treatable disease will not be missed. © 2016 by the Association of Clinical Scientists, Inc.

    2015-01-01

    Full Text Available Netherton syndrome, a rare autosomal recessive genetic disorder, is classified as an ichthyosiform syndrome. In this report we present the case of a neonate with erythroderma shortly after birth, accompanied by severe hypernatremia, recurrent infections, transient hyperaldosteronism, and signs of growth hormone (GH deficiency. DNA molecular analysis in the SPINK5 gene revealed heterozygosity in our index patient for 238insG and 2468delA frameshift mutations in exons 4 and 26, respectively, in the maternal allele and 1431-12G>A splice-site mutation in intron 15 in the paternal allele as well as the missense variation E420K in homozygous state. Combination of the identified mutations along with transient hyperaldosteronism and possible GH deficiency have not been described before. Accordingly, the importance of early multidisciplinary approach is highlighted, in order to reach accurate diagnosis, initiate prompt treatment, and ensure survival with fewer disease complications.

    Constitutional mismatch repair deficiency (CMMRD) is a devastating cancer predisposition syndrome for which data regarding clinical manifestations, molecular screening tools and management are limited. We established an international CMMRD consortium and collected comprehensive clinical and genetic data. Molecular diagnosis of tumour and germline biospecimens was performed. A surveillance protocol was developed and implemented. Overall, 22/23 (96%) of children with CMMRD developed 40 different tumours. While childhood CMMRD related tumours were observed in all families, Lynch related tumours in adults were observed in only 2/14 families (p=0.0007). All children with CMMRD had café-au-lait spots and 11/14 came from consanguineous families. Brain tumours were the most common cancers reported (48%) followed by gastrointestinal (32%) and haematological malignancies (15%). Importantly, 12 (30%) of these were low grade and resectable cancers. Tumour immunohistochemistry was 100% sensitive and specific in diagnosing mismatch repair (MMR) deficiency of the corresponding gene while microsatellite instability was neither sensitive nor specific as a diagnostic tool (psyndrome where family history of cancer may not be contributory. Screening tumours and normal tissues using immunohistochemistry for abnormal expression of MMR gene products may help in diagnosis and early implementation of surveillance for these children.

    A case of heterotopic ossification (myositis ossificans) secondary to the central nervous system complications of acquired immune deficiency syndrome (AIDS) is reported. Because of the overwhelming suspicion of infection in this patient, this diagnosis was not considered until a gallium scan revealed the typical findings of heterotopic ossification. Because of the increasing utilization of gallium imaging in the AIDS population, every imaging specialist should be aware of this potential disorder

    Laron syndrome (LS) is a unique model of congenital IGF-I deficiency. It is characterized by dwarfism and obesity, and is caused by deletion or mutations of the growth hormone receptor (GH-R) gene. It is hypothesized that LS is an old disease originating in Indonesia and that the mutated gene spread to South Asia, the Middle East, the Mediterranean region and South America.

    Full Text Available OBJECTIVES: The aim of this study was to examine the effects of antenatal exposure to iron deficiency anemia (IDA and common mental disorders (CMD on cognitive development of 6 months old infants in a developing country. METHODS: A prospective population-based study in a rural province in Vietnam, which enrolled pregnant women at 12-20 weeks gestation and followed them up with their infants until six months postpartum. Criteria for IDA were Hb 30 years and primiparity had an indirect adverse effect on infants' Bayley cognitive scores. CONCLUSIONS: These findings suggest that antenatal IDA and CMD both have adverse effects on child cognitive development, which if unrecognized and unaddressed are likely to be lasting. It is crucial that both these risks are considered by policy makers, clinicians, and researchers seeking to improve child cognitive function in developing countries.

    In a brief review of the Se deficiency syndrome in ruminants, studies using non-isotopic methods are applied to an introductory description of the disease. They include methods currently applied for determining Se deficiency status in feed and in ruminant animals. Detection of potential white muscle disease in lambs and calves is discussed. The application of 75 Se in studies on absorption, tissue distribution and excretion under feeding regimes with different Se levels and partly with addition of SO 4 ions or vitamin E is reviewed. In vitro studies with 75 Se include a description of the 75 Se uptake test with red blood cells, the metabolism of selenite, selenate and selenomethionine in rumen microorganisms, and the distribution of 75 Se in cow's and goat's milk. Methods of Se supplementation in Se-deficient areas are summarized and tests with 75 Se-labelled ruminal pellets in sheep and cattle are described. The Se toxicity syndrome is surveyed with respect to causative agents, symptomatology and gross pathology. Special reference is made to the blind staggers and the alkali disease types of selenosis. Isotope techniques are found to be less frequently applied in studies on Se toxicity than in Se deficiency studies. (author)

    Rapid-onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) is a rare and complex pediatric syndrome, essentially caused by dysfunction of 3 vital systems regulating endocrine, respiratory, and autonomic nervous system functioning. The clinical spectrum of ROHHAD is broad, but sleep/wake disorders have received relatively little attention so far, although the central hypothalamic dysfunction would make the occurrence of sleep symptoms likely. In this case report, we expand the phenotype of ROHHAD with a number of striking sleep symptoms that together can be classified as a secondary form of narcolepsy. We present a 7-year-old girl with ROHHAD who displayed the classic features of narcolepsy with cataplexy: excessive daytime sleepiness with daytime naps, visual hallucinations, and partial cataplexy reflected in intermittent loss of facial muscle tone. Nocturnal polysomnography revealed sleep fragmentation and a sleep-onset REM period characteristic for narcolepsy. The diagnosis was confirmed by showing an absence of hypocretin-1 in the cerebrospinal fluid. We discuss potential pathophysiological implications as well as symptomatic treatment options.

    Approximately 60 cases of GHRD (Laron syndrome) were reported before 1990 and half of these were from Israel. We have described 47 additional patients from an inbred population of South Ecuador and have emphasized certain clinical features including: markedly advanced osseous maturation for height age; normal body proportions in childhood but child-like proportions in adults; much greater deviation of stature than head size, giving an appearance of large cranium and small facies; underweight in childhood despite the appearance of obesity and true obesity in adulthood; blue scleras; and limited elbow extension. The Ecuadorean patients differed markedly and most importantly from the other large concentration, in Israel, by being of normal or superior intelligence, suggesting a unique linkage in the Ecuadorean population. The Ecuadorean population also differed in that those patients coming from Loja province had a markedly skewed sex ratio (19 females: 2 males), while those from El Oro province had a normal sex distribution (14 females: 12 males). The phenotypic similarity between the El Oro and Loja patients indicates that this abnormal sex distribution is not a direct result of the GHRD.

    Full Text Available In patients with fragile X syndrome (FXS, sleep problems are commonly observed but are not well characterized. In animal models of FXS (dfmr1 and Fmr1 knockout (KO/Fxr2 heterozygote circadian rhythmicity is affected, but sleep per se has not been examined. We used a home-cage monitoring system to assess total sleep time in both light and dark phases in Fmr1 KO mice at different developmental stages. Fmr1 KOs at P21 do not differ from controls, but genotype × phase interactions in both adult (P70 and P180 groups are statistically significant indicating that sleep in Fmr1 KOs is reduced selectively in the light phase compared to controls. Our results show the emergence of abnormal sleep in Fmr1 KOs during the later stages of brain maturation. Treatment of adult Fmr1 KO mice with a GABAB agonist, R-baclofen, did not restore sleep duration in the light phase. In adult (P70 Fmr1 KO/Fxr2 heterozygote animals, total sleep time was further reduced, once again in the light phase. Our data highlight the importance of the fragile X genes (Fmr1 and Fxr2 in sleep physiology and confirm the utility of these mouse models in enhancing our understanding of sleep disorders in FXS.

    Neurofibromatosis-Noonan syndrome (NFNS) is a distinct entity which shows the features of both NF1 (neurofibromatosis 1) and Noonan syndrome (NS). While growth hormone deficiency (GHD) has been relatively frequently identified in NF1 and NS patients, there is limited experience in NFNS cases. The literature includes only one case report of a NFNS patient having GHD and that report primarily focuses on the dermatological lesions that accompany the syndrome and not on growth hormone (GH) treatment. Here, we present a 13-year-old girl who had clinical features of NFNS with a mutation in the NF1 gene. The case is the first NFNS patient reported in the literature who was diagnosed to have GHD and who received GH treatment until reaching final height. The findings in this patient show that short stature is a feature of NFNS and can be caused by GHD. Patients with NFNS who show poor growth should be evaluated for GHD.

  1. Small for Gestational Age and Magnesium: Intrauterine magnesium deficiency may induce metabolic syndrome in later life

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Magnesium deficiency during pregnancy as a result of insufficient or low intake of magnesium is common in developing and developed countries. Previous reports have shown that intracellular magnesium of cord blood platelets is lower among small for gestational age (SGA groups than that of appropriate for gestational age (AGA groups, suggesting that intrauterine magnesium deficiency may result in SGA. Additionally, the risk of adult-onset diseases such as insulin resistance syndrome is greater among children whose mothers were malnourished during pregnancy, and who consequently had a low birth weight. In a number of animal models, poor nutrition during pregnancy leads to offspring that exhibit pathophysiological changes similar to human diseases. The offspring of pregnant rats fed a magensium restricted diet have developed hypermethylation in the hepatic 11β-hydroxysteroid dehydrogenase-2 promoter. These findings indicate that maternal magnesium deficiencies during pregnancy influence regulation of non-imprinted genes by altering the epigenetic regulation of gene expression, thereby inducing different metabolic phenotypes. Magnesium deficiency during pregnancy may be responsible for not only maternal and fetal nutritional problems, but also lifelong consequences that affect the offspring throughout their life. Epidemiological, clinical, and basic research on the effects of magnesium deficiency now indicates underlying mechanisms, especially epigenetic processes.

    To evaluate the relation between Pi-deficiency syndrome (PDS) pattern and metabolic syndrome (MS) in patients with polycystic ovarian syndrome (PCOS), for exploring their internal pathologic mechanism. Among the 102 PCOS patients, 22 complicated with MS (PCOS-MS) and 80 not complicated with MS (PCOS-NMS), the Chinese medicine syndrome pattern was differentiated as PDS in 50 patients and non-PDS in 52. The clinical data, in terms of fasting blood glucose (FBG), fasting insulin (FINS), waistline, body weight (BW), stature, blood pressure (BP), etc. was collected and compared and the relation between data was analyzed. Levels of FINS and homeostasis model of assessment for insulin resistence index (HOMA-IR), in PCOS-MS patients were significantly higher than those in PCOS-NMS patients, also higher in patients of PDS pattern than those of non-PDS pattern (P 0.05). PCOS patients of PDS pattern are the high-risk population of MS, which might be related with the insulin resistance. So, early treatment of PCOS, especially on patients of PDS pattern, is of important significance for preventing the complication, as MS, of the disease.

  9. Magnesium deficiency and metabolic syndrome: stress and inflammation may reflect calcium activation.

    Science.gov (United States)

    Rayssiguier, Yves; Libako, Patrycja; Nowacki, Wojciech; Rock, Edmond

    2010-06-01

    Magnesium (Mg) intake is inadequate in the western diet and metabolic syndrome is highly prevalent in populations around the world. Epidemiological studies suggest that high Mg intake may reduce the risk but the possibility of confounding factors exists, given the strong association between Mg and other beneficial nutriments (vegetables, fibers, cereals). The concept that metabolic syndrome is an inflammatory condition may explain the role of Mg.Mg deficiency results in a stress effect and increased susceptibility to physiological damage produced by stress. Stress activates the hypothalamic-pituitary-adrenal axis (HPA) axis and the sympathetic nervous system. The activation of the renin-angiotensin-aldosterone system is a factor in the development of insulin resistance by increasing oxidative stress. In both humans and rats, aldosteronism results in an immunostimulatory state and leads to an inflammatory phenotype. Stress response induces the release of large quantities of excitatory amino acids and activates the nuclear factor NFkappaB, promoting translation of molecules involved in cell regulation, metabolism and apoptosis. The rise in neuropeptides is also well documented. Stress-induced HPA activation has been identified to play an important role in the preferential body fat accumulation but evidence that Mg is involved in body weight regulation is lacking. One of the earliest events in the acute response to stress is endothelial dysfunction. Endothelial cells actively contribute to inflammation by elaborating cytokines, synthesizing chemical mediators and expressing adhesion molecules. Experimental Mg deficiency in rats induces a clinical inflammatory syndrome characterized by leukocyte and macrophage activation, synthesis of inflammatory cytokines and acute phase proteins, extensive production of free radicals. An increase in extracellular Mg concentration decreases inflammatory effects, while reduction in extracellular Mg results in cell activation. The

    2017-01-01

    Increased predisposition of schizophrenia patients (SP) to development of obesity and insulin resistance suggested common signaling pathway between metabolic syndrome (MetS) and schizophrenia. Deficiency of kynurenine-3-monooxygenase (KMO), enzyme catalyzing formation of 3-hydroxykynurenine (3-HK) from kynurenine (Kyn), a tryptophan (Trp) metabolite, might contribute to development of MetS as suggested by non-expression of KMO genes in human fat tissue and elevated serum concentrations of Kyn and its metabolites, kynurenic (KYNA) and anthranilic (ANA) acids, in diabetic patients and Zucker fatty rats (ZFR). Markers of KMO deficiency: decreased 3-HK and elevated Kyn, KYNA and ANA, were observed in brains and spinal fluids of SP, and in brains and serum of experimental animals with genetically- or pharmacologically-induced KMO deficiency. However, elevated concentrations of ANA and decreased 3-HK were reported in serum of SP without concurrent increase of Kyn and KYNA. Present study aimed to re-assess serum Kyn metabolites (HPLC-MS) in a sub-group of SP with elevated KYNA. We found increased Kyn concentrations (by 30%) and Kyn:Trp ratio (by 20%) in serum of SP with elevated KYNA concentrations (by 40%). Obtained results and our previous data suggest that peripheral KMO deficiency might be manifested by, at least, two different patterns: elevated ANA with decreased 3-HK; and elevated KYNA and KYN. The latter pattern was previously described in type 2 diabetes patients and might underline increased predisposition of SP to development of MetS. Assessment of peripheral KMO deficiency might identify SP predisposed to MetS. Attenuation of the consequences of peripheral KMO deficiency might be a new target for prevention/treatment of obesity and diabetes in SP.

    Full Text Available Introduction. Alkaline earth metal deficiency is recognized as a cause of both seizure and long QT syndrome. Their deficiency can have significant repercussions on the function of cells, tissues, and organs of the body. An understanding of the role of electrolytes allows an appreciation of the significance of depleted levels on cell function. Case Report. A 65-year-old lady was admitted with symptoms of chest discomfort, vomiting, increased stoma output, and dizziness. Two days following admission she suffered a tonic-clonic seizure. ECG review demonstrated a prolonged QTc interval, raising the possibility of an underlying Torsades de Pointes as the precipitant. This was attributed to electrolyte disturbance arising as a result of multiple aetiologies. Discussion. This paper highlights the multisystem effects of electrolyte disturbance, with emphasis upon its role in precipitating cardiac arrhythmia and neurological symptoms.

The neuro-radiological findings of the case demonstrate the degenerative and metabolic alterations in various regions of cortex, white matter and subcortical areas in the brain. Mental disorder of the case is almost indistinguishable from that of schizophrenia, but the psychotic feature is regarded as an atypical or mixed organic brain syndrome according to the classification in the third edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-III).

    We report a case of a 53-year-old man presenting with depressed alertness and severe excessive sleepiness in the setting of neurosarcoidosis. Neuroimaging demonstrated hypothalamic destruction due to sarcoidosis with a CSF hypocretin level of 0 pg/mL. The patient also experienced respiratory depression that presumably resulted from hypocretin-mediated hypothalamic dysfunction as a result of extensive diencephalic injury. This is a novel case, demonstrating both hypocretin deficiency syndrome, as well as respiratory dysfunction from destruction of hypocretin neurons and extensive destruction of key diencephalic structures secondary to the underlying neurosarcoidosis. © 2015 American Academy of Sleep Medicine.

The subject, as in other reported cases, had a chronic hemolytic anemia characterized by stomatocytosis, reduced osmotic fragility, and abnormal autohemolysis correctable with the addition of glucose. The 51 Cr red cell survival studies showed the spleen to be the preferential site of red cell destruction and splenectomy produced a dramatic improvement in red cell survival. The topic of Rh deficiency syndrome (Rhnull and Rhmod) is briefly reviewed with regard to the number of cases reported, to genetic aspects, to the hematological findings, and to the results of splenectomy

    Full Text Available Disorders of sex development refer to a collection of congenital conditions in which atypical development of chromosomal, gonadal, or anatomic sex occurs. Studies of 46,XY DSD have focused largely on gender identity, gender role, and sexual orientation. Few studies have focused on other domains, such as physical and mental health, that may contribute to a person's quality of life. The current review focuses on information published since 1955 pertaining to psychological well-being, cognition, general health, fertility, and sexual function in people affected by androgen insensitivity syndromes, 5- reductase-2 deficiency, or 17-hydroxysteroid dehydrogenase-3 deficiency—reared male or female. The complete form of androgen insensitivity syndrome has been the focus of the largest number of investigations in domains other than gender. Despite this, all of the conditions included in the current review are under-studied. Realms identified for further study include psychological well-being, cognitive abilities, general health, fertility, and sexual function. Such investigations would not only improve the quality of life for those affected by DSD but may also provide information for improving physical and mental health in the general population.

    Vitamin D modulates innate and adaptive immune responses, and vitamin D deficiency is associated with increased mortality in hospitalized patients with pneumonia. We evaluated the prevalence of vitamin D deficiency in Korean patients with acute respiratory distress syndrome (ARDS) and its effect on the clinical outcomes of ARDS. We retrospectively analyzed the data of 108 patients who had a measured serum level of 25-hydroxy vitamin D3 (25(OH)D3) at the time of diagnosis with ARDS. The clinical outcomes were evaluated based on 25(OH)D3 levels of 20 ng/mL and stratified by quartiles of 25(OH)D3 levels. The mean age of patients was 59.4 years old; 77 (71.3%) were male. Vitamin D deficiency was found in 103 patients (95.4%). The mean 25(OH)D3 level was 8.3 ± 7.0 ng/mL. Neither in-hospital mortality (40.0% vs. 68.0%) nor 6-month mortality (40.0% vs. 71.8%) significantly differed between groups. There were no significant differences in 25(OH)D3 level between survivors (8.1 ± 7.6 ng/mL) and non-survivors (8.5 ± 6.8 ng/mL, p = 0.765). There were no trends toward a difference in mortality among quartiles of 25(OH)D3 levels. However, 25(OH)D3 levels were inversely related with length of hospital stay and intensive care unit stay among in-hospital survivors. Vitamin D deficiency was prevalent in Korean patients with ARDS. However, levels of vitamin D were not associated with mortality. A large, prospective study is needed to evaluate the effects of vitamin D deficiency on clinical outcomes of ARDS.

    Full Text Available Ornithine transcarbamylase deficiency (OTCD is the most common type urea cycle enzyme deficiencies. This syndrome results from a deficiency of the mitochondrial enzyme ornithine transcarbamylase, which catalyzes the conversion of ornithine and carbamoyl phosphate to citrullin. Our case was a 28-year-old female diagnosed with OTCD following neurocognitive deficit during her first pregnancy. Although hyperammonemia was suspected as the cause of the patient's mental changes, there was no evidence of chronic liver disease. Plasma amino acid and urine organic acid analysis revealed OTCD. After combined modality treatment with arginine, sodium benzoate and hemodialysis, the patient's plasma ammonia level stabilized and her mental status returned to normal. At last she recovered without any damage left.

    Anhedonia is a condition that leads to the loss of feelings pleasure in response to natural reinforcers like food, sex, exercise, and social activities. This disorder occurs in addiction, and an array of related neuropsychiatric syndromes, including schizophrenia, depression, and Post Traumatic Stress Disorder (PTSD). Anhedonia may by due to derangements in mesolimbic dopaminergic pathways and their terminal fields (e.g., striatum, amygdala, and prefrontal cortex) that persist long after the traces of the causative drugs are eliminated (pharmacokinetically). Here we postulate that anhedonia is not a distinct entity but is rather an epiphenomenon of hypodopaminergic states and traits arising from the interaction of genetic traits and epigenetic neurobiological alterations in response to environmental influences. Moreover, dopaminergic activity is rather complex, and so it may give rise to differential pathophysiological processes such as incentive sensitization, aberrant learning and stress-like "anti-reward" phenomena. These processes may have additive, synergistic or antagonistic interactions with the concurrent reward deficiency states leading in some instances to more severe and long-lasting symptoms. Operant understanding of the neurogenetic antecedents to reward deficiency syndrome (RDS) and the elucidation of reward gene polymorphisms may provide a map for accessing an individual's genetic risk for developing Anhedonia. Prevention techniques that can restore homeostatic balance via physiological activation of dopaminergic receptors (D2/D3) may be instrumental for targeting not only anhedonia per se but also drug craving and relapse.

    Animal and clinical studies have shown that excessive amounts of growth hormone or insulin-like growth factor-I (IGF-I) promote the development of diabetes and diabetic retinopathy. Forthwith, we present two patients with congenital IGF-I deficiency who developed type II diabetes and subsequently retinopathy. Eighteen adult patients with classical Laron syndrome (8 males, 10 females, aged 20-62 years) were followed by us since childhood or underwent fundus photography with a Nikon NF 505 instrument. Three had been treated in childhood with IGF-I, the rest were never treated, including the two patients reported. Two never-treated patients were diagnosed with type II diabetes (DM) at ages 39 and 41 respectively. There was no diabetes in the families. Oral treatment was followed by insulin injections. Metabolic control was not optimal and one patient developed proliferative diabetic retinopathy, necessitating laser surgery. He also has nephropathy and severe neuropathy. The other patient has background diabetic retinopathy and has developed, progressively, exudates, microaneurisms, hemorrhages and clinically significant macular edema. He also has subacute ischemic heart disease. Our findings show that congenital IGF-I deficiency, similar to excess, causes vascular complications of DM, denoting also that vascular endothelial growth factor can induce neovascularization in the presence of congenital IGF-I deficiency.

    Full Text Available Abstract Background About 20–30% of persons with HIV infection, especially those living in countries with limited resources, experience an immune reconstitution inflammatory syndrome (IRIS after starting antiretroviral treatment. The active form of vitamin D, 1,25-dihydroxyvitamin D, is a key player in the clearance of pathogens and influences the level of inflammation and macrophage activation. Presentation of the hypothesis We hypothesize that low availability of 1,25-dihydroxyvitamin D, either due to vitamin D deficiency or due to polymorphisms in the vitamin D receptor or in its activating/inactivating enzymes, contributes to the appearance of IRIS. Furthermore, drug interactions with the enzymatic pathways of vitamin D could favour the development of IRIS. Testing the hypothesis Our hypothesis could be explored by a case-control study to assess the prevalence of vitamin D deficiency in HIV-infected patients on antiretroviral treatment who develop and do not develop IRIS. Implications of the hypothesis If the role of vitamin D in IRIS is confirmed, we would be able to screen patients at risk for IRIS by screening for vitamin D deficiency. After confirmation by means of a clinical trial, vitamin D supplementation could be a cheap and safe way to reduce the incidence of IRIS.

    Carbohydrate sulfotransferase 14/dermatan 4-O-sulfotransferase-1 (CHST14/D4ST1) deficiency represents a specific form of Ehlers-Danlos syndrome (EDS) caused by recessive loss-of-function mutations in CHST14. The disorder has been independently termed "adducted thumb-clubfoot syndrome", "EDS, Kosho type", and "EDS, musculocontractural type". To date, 31 affected patients from 21 families have been described. Clinically, CHST14/D4ST1 deficiency is characterized by multiple congenital malformations (craniofacial features including large fontanelle, hypertelorism, short and downslanting palpebral fissures, blue sclerae, short nose with hypoplastic columella, low-set and rotated ears, high palate, long philtrum, thin upper lip vermilion, small mouth, and micro-retrognathia; multiple congenital contractures including adduction-flexion contractures and talipes equinovarus as well as other visceral or ophthalmological malformations) and progressive multisystem fragility-related complications (skin hyperextensibility, bruisability, and fragility with atrophic scars; recurrent dislocations; progressive talipes or spinal deformities; pneumothorax or pneumohemothorax; large subcutaneous hematomas; and diverticular perforation). Etiologically, multisystem fragility is presumably caused by impaired assembly of collagen fibrils resulting from loss of dermatan sulfate (DS) in the decorin glycosaminoglycan side chain that promotes electrostatic binding between collagen fibrils. This is the first reported human disorder that specifically affects biosynthesis of DS. Its clinical characteristics indicate that CHST14/D4ST1 and, more fundamentally, DS, play a critical role in fetal development and maintenance of connective tissues in multiple organs. Considering that patients with CHST14/D4ST1 deficiency develop progressive multisystem fragility-related manifestations, establishment of a comprehensive and detailed natural history and health-care guidelines as well as further elucidation

    BACKGROUND & AIMS: Patients with bi-allelic germline mutations in mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2) develop a rare but severe variant of Lynch syndrome called constitutional MMR deficiency (CMMRD). This syndrome is characterized by early-onset colorectal cancers, lymphomas...... or leukemias, and brain tumors. There is no satisfactory method for diagnosis of CMMRD because screens for mutations in MMR genes are noninformative for 30% of patients. MMR-deficient cancer cells are resistant to genotoxic agents and have microsatellite instability (MSI), due to accumulation of errors...

    Constitutional mismatch repair deficiency (CMMRD) syndrome is a childhood cancer predisposition syndrome involving biallelic germline mutations of MMR genes, poorly recognised by clinicians so far. Retrospective review of all 31 patients with CMMRD diagnosed in French genetics laboratories in order to describe the characteristics, treatment and outcome of the malignancies and biological diagnostic data. 67 tumours were diagnosed in 31 patients, 25 (37%) Lynch syndrome-associated malignancies, 22 (33%) brain tumours, 17 (25%) haematological malignancies and 3 (5%) sarcomas. The median age of onset of the first tumour was 6.9 years (1.2-33.5). Overall, 22 patients died, 9 (41%) due to the primary tumour. Median survival after the diagnosis of the primary tumour was 27 months (0.26-213.2). Failure rate seemed to be higher than expected especially for T-cell non-Hodgkin's lymphoma (progression/relapse in 6/12 patients). A familial history of Lynch syndrome was identified in 6/23 families, and consanguinity in 9/23 families. PMS2 mutations (n=18) were more frequent than other mutations (MSH6 (n=6), MLH1 (n=4) and MSH2 (n=3)). In conclusion, this unselected series of patients confirms the extreme severity of this syndrome with a high mortality rate mostly related to multiple childhood cancers, and highlights the need for its early detection in order to adapt treatment and surveillance.

    The aim of this study was to examine the effects of antenatal exposure to iron deficiency anemia (IDA) and common mental disorders (CMD) on cognitive development of 6 months old infants in a developing country. A prospective population-based study in a rural province in Vietnam, which enrolled pregnant women at 12-20 weeks gestation and followed them up with their infants until six months postpartum. Criteria for IDA were Hb cognitive development was assessed by Bayley Scales of Infant and Toddler Development, 3rd Ed. Path analyses were performed to determine the direct and indirect, partly or fully mediated, causal effects of the antenatal exposures. A total of 497 pregnant women were recruited, of those 378 women provided complete data which were included in the analyses. Statistically significant direct adverse effects of persistent antenatal IDA (estimated difference of -11.62 points; 95% CI -23.01 to -0.22) and antenatal CMD (-4.80 points; 95% CI: -9.40 to -0.20) on infant Bayley cognitive scores at six months were found. Higher birthweight, household wealth, and self-rated sufficient supply of breastmilk were associated with higher cognitive scores. Maternal age >30 years and primiparity had an indirect adverse effect on infants' Bayley cognitive scores. These findings suggest that antenatal IDA and CMD both have adverse effects on child cognitive development, which if unrecognized and unaddressed are likely to be lasting. It is crucial that both these risks are considered by policy makers, clinicians, and researchers seeking to improve child cognitive function in developing countries.

    Monoallelic germline mutations in one of the DNA mismatch repair (MMR) genes cause Lynch syndrome, with a high lifetime risks of colorectal and endometrial cancer at adult age. Less well known, is the constitutional mismatch repair deficiency (CMMRD) syndrome caused by biallelic germline mutations in MMR genes. This syndrome is characterized by the development of childhood cancer. Patients with CMMRD are at extremely high risk of developing multiple cancers including hematological, brain and intestinal tumors. Mutations in MMR genes impair DNA repair and therefore most tumors of patients with CMMRD are hypermutated. These mutations lead to changes in the translational reading frame, which consequently result in neoantigen formation. Neoantigens are recognized as foreign by the immune system and can induce specific immune responses. The growing evidence on the clinical efficacy of immunotherapies, such as immune checkpoint inhibitors, offers the prospect for treatment of patients with CMMRD. Combining neoantigen-based vaccination strategies and immune checkpoint inhibitors could be an effective way to conquer CMMRD-related tumors. Neoantigen-based vaccines might also be a preventive treatment option in healthy biallelic MMR mutation carriers. Future studies need to reveal the safety and efficacy of immunotherapies for patients with CMMRD. Copyright © 2017 The Author(s). Published by Elsevier B.V. All rights reserved.

    Biallelic germline mutations in mismatch repair genes predispose to constitutional mismatch repair deficiency syndrome (CMMR-D). The condition is characterized by a broad spectrum of early-onset tumors, including hematological, brain and bowel and is frequently associated with features of Neurofibromatosis type 1. Few definitive screening recommendations have been suggested and no published reports have described predictive testing. We report on the first case of predictive testing for CMMR-D following the identification of two non-consanguineous parents, with the same heterozygous mutation in MLH1: c.1528C > T. The genetic counseling offered to the family, for their two at-risk daughters, is discussed with a focus on the ethical considerations of testing children for known cancer-causing variants. The challenges that are encountered when reporting on heterozygosity in a child younger than 18 years (disclosure of carrier status and risk for Lynch syndrome), when discovered during testing for homozygosity, are addressed. In addition, the identification of CMMR-D in a three year old, and the recommended clinical surveillance that was proposed for this individual is discussed. Despite predictive testing and presymptomatic screening, the sudden death of the child with CMMR-D syndrome occurred 6 months after her last surveillance MRI. This report further highlights the difficulty of developing guidelines, as a result of the rarity of cases and diversity of presentation.

    Violent behavior has frequently been reported in cases of Capgras' delusion, a misidentification syndrome characterized by the false belief that imposters have replaced people familiar to the individual. To better understand the relationship between Capgras' syndrome and violence. After a brief overview of the scientific knowledge of delusional misidentification syndromes, we present two cases of psychotic sons suffering from this kind of delusion who killed their mothers and we analyzed the phenomenology of Capgras' delusion in-depth, focusing on the role of this syndrome in the etiology of violence. Capgras' syndrome may be a specific risk factor for violence towards others, particularly the murder of the delusionally misidentified person. Looking for the signs of Capgras' syndrome may be crucial to assessing the risk of violence in mentally disordered patients. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

The deletion typically involves the terminal band 22q13.3 and has been associated with both familial and de-novo translocations. We report the case of an 11-year-old Turkish girl with 22q13.3 deletion syndrome presenting with repeated seizures during the course of a rubella infection. We also review the clinical features of 22q13.3 deletion syndrome and emphasize the importance of considering a rare microdeletion syndrome for idiopathic mental retardation when results of a routine karyotype analysis are normal. To the best of our knowledge, this is the first reported case of a Turkish patient with isolated 22q13.3 deletion syndrome. [Cukurova Med J 2015; 40(1.000: 169-173

Recent studies estimated that colorectal cancer risk for relatives of suspected Lynch syndrome cases is lower than for relatives of those with MMR gene mutations, but higher than for relatives of those with tumor MMR deficiency resulting from methylation of the MLH1 gene promoter. The cause of tumor MMR deficiency in suspected Lynch syndrome cases is likely due to either unidentified germline MMR gene mutations, somatic cell mosaicism, or biallelic somatic

    To analyze the correlation between risk factors and ischemic cerebral stroke of wind-phlegm collateral obstruction syndrome and qi deficiency blood stasis syndrome. Totally 900 patients of the two syndrome types were recruited. Risk factors correlated to ischemic cerebral stroke such as gender, age, time of onset, site of infarction, tongue proper, tongue fur, pulse picture, hypertension, diabetes, past stroke history, hyperlipidemia, hematocrit, smoking, drinking, genetic factor, blood type, complications were analyzed using Chi-square test and non-conditional Logistic regression analysis. Statistical significance existed between the two syndrome types in age (X2 = 8.2392, P = 0.0413), hyperlipidemia (X2 = 4.8386, P = 0.0278), tongue proper (X2 = 7.9470, P = 0.0048), and tongue fur (X2 = 4.3298, P = 0.0375). Statistical significance existed between the two syndrome types in hyperlipidemia, tongue proper, and tongue fur, and their OR value was 0.699 (P = 0.0282), 0.332 (P =0.0071), and 0.667 (P = 0.0382) respectively. The OR value of the past stroke history was 3.226 (P = 0.0314), that of complications 0.203 (P = 0.0705), and that of anterior circulation infarction 0.214 (P = 0.0098). Among different ages groups, the constituent ratio of qi deficiency blood stasis syndrome was obviously higher than that of wind-phlegm collateral obstruction syndrome. Besides, patients of qi deficiency blood stasis syndrome were liable to suffer from hyperlipidemia, anterior circulation infarction, and complications. The age, blood lipid levels, site of infarction, complications are closely correlated with Chinese syndrome types of ischemic cerebral stroke, which can provide objective indices for typing ischemic cerebral stroke.

    Ten cases of acquired antibody deficiency syndrome with chronic granulomatous infection were diagnosed in our hospital during the past 10 years. We were able to perform a retrospective analysis of the initial and follow-up chest radiographs in 8 of these patients. The following pathological findings could be demonstrated: 1. increased bronchovascular markings in the basal lung fields, 2. reticular densities in the middle and basal lung fields, 3. confluent nodular densities of varying size in the periphery of the basal and middle fields, 4. pulmonary infiltrates in the middle and lower lobes, 5. hilar node enlargement of moderate extent. Findings 2, 3 and 5 completely disappeared under steroid therapy whereas 1 showed only partial recovery. If both the radiologic and serologic findings are considered, it is possible to differentiate this disease from sarcoidosis. (orig.) [de

    Hoyeraal-Hreidarsson syndrome (HHS), a severe variant of dyskeratosis congenita (DC), is characterized by early onset bone marrow failure, immunodeficiency and developmental defects. Several factors involved in telomere length maintenance and/or protection are defective in HHS/DC, underlining the relationship between telomere dysfunction and these diseases. By combining whole-genome linkage analysis and exome sequencing, we identified compound heterozygous RTEL1 (regulator of telomere elongation helicase 1) mutations in three patients with HHS from two unrelated families. RTEL1 is a DNA helicase that participates in DNA replication, DNA repair and telomere integrity. We show that, in addition to short telomeres, RTEL1-deficient cells from patients exhibit hallmarks of genome instability, including spontaneous DNA damage, anaphase bridges and telomeric aberrations. Collectively, these results identify RTEL1 as a novel HHS-causing gene and highlight its role as a genomic caretaker in humans.

    2017-03-01

    Full Text Available Growth hormone (GH is an essential element for normal growth. However, reports of normal growth without GH have been made in patients who have undergone brain surgery for craniopharyngioma. Normal growth without GH can be explained by hyperinsulinemia, hyperprolactinemia, elevated leptin levels, and GH variants; however, its exact mechanism has not been elucidated yet. We diagnosed a female patient aged 13 with combined pituitary hormone deficiency (CPHD caused by pituitary stalk interruption syndrome (PSIS. The patient has experienced recurrent hypoglycemic seizures since birth, but reached the height of 160 cm at the age of 13, showing normal growth. She grew another 8 cm for 3 years after the diagnosis, and she reached her final adult height of 168 cm which was greater than the midparental height, at the age of 16. The patient's blood GH and insulin-like growth factor-I levels were consistently subnormal, although her insulin levels were normal. Her physical examination conducted at the age of 15 showed truncal obesity, dyslipidemia, and osteoporosis, which are metabolic features of GH deficiency (GHD. Herein, we report a case in which a PSIS-induced CPHD patient attained her final height above mid parental height despite a severe GHD.

    Objective The association between type 2 diabetes and low testosterone has been well recognized. However, testosterone levels in men with prediabetes have been rarely reported. We aimed to investigate whether prediabetes was associated with an increased risk of testosterone deficiency. Methods This study included 1,306 men whose sex hormones was measured during a medical examination. Serum total testosterone and sex hormone-binding globulin were measured; free and bioavailable testosterone concentrations were calculated by Vermeulen’s formula. Prediabetes was defined by impaired fasting glucose (IFG), impaired postprandial glucose (IPG), or glycated hemoglobin (HbA1c) 5.7%-6.4%. Logistic regression was performed to obtain the odds ratios (OR) for subnormal total testosterone (prediabetic and diabetic men compared with normoglycemic individuals, while adjusting for age, BMI, waist circumference, and metabolic syndrome (MetS). Results Normoglycemia, prediabetes, and diabetes were diagnosed in 577 (44.2%), 543 (41.6%), and 186 (14.2%) men, respectively. Prediabetes was associated with an increased risk of subnormal total testosterone compared to normoglycemic individuals (age-adjusted OR=1.87; 95%CI=1.38-2.54). The risk remained significant in all multivariate analyses. After adjusting for MetS, the OR in prediabetic men equals that of diabetic patients (1.49 versus 1.50). IFG, IPG, and HbA1c 5.7%-6.4% were all associated with an increased risk of testosterone deficiency, with different levels of significance in multivariate analyses. However, neither prediabetes nor diabetes was associated with subnormal free testosterone in multivariate analyses. Conclusions Prediabetes is associated with an increased risk of testosterone deficiency, independent of obesity and MetS. After adjusting for MetS, the risk equals that of diabetes. Our data suggest that testosterone should be measured routinely in men with prediabetes. PMID:24069277

    2016-03-01

    Constitutional mismatch repair deficiency (CMMRD) syndrome is one of the rare diseases associated with a high risk of cancer. Causative mutations are found in DNA mismatch repair genes PMS2, MSH6, MSH2 or MLH1 that are well known in the context of Lynch syndrome. CMMRD follows an autosomal recessive inheritance trait and is characterized by childhood brain tumors and hematological malignancies as well as gastrointestinal cancer in the second and third decades of life. There is a high risk of multiple cancers, occurring synchronously and metachronously. In general, the prognosis is poor. About one third of CMMRD patients develop hematological malignancies as primary (sometimes the only) malignancy or as secondary neoplasm. T-cell non-Hodgkin lymphomas, mainly of mediastinal origin, are the most frequent hematological malignancies. Besides malignant diseases, non-neoplastic features are frequently observed, e.g. café-au-lait spots sometimes resembling neurofibromatosis type I, hypopigmented skin lesions, numerous adenomatous polyps, multiple pilomatricomas, or impaired immunoglobulin class switch recombination. Within the present review, we summarize previously published CMMRD patients with at least one hematological malignancy, provide an overview of steps necessary to substantiate the diagnosis of CMMRD, and refer to the recent most relevant literature.

  14. The heartstrings mutation in zebrafish causes heart/fin Tbx5 deficiency syndrome.

    2002-10-01

    Holt-Oram syndrome is one of the autosomal dominant human "heart-hand" disorders, with a combination of upper limb malformations and cardiac defects. Holt-Oram syndrome is caused by mutations in the TBX5 gene, a member of a large family of T-box transcription factors that play important roles in cell-type specification and morphogenesis. In a screen for mutations affecting zebrafish cardiac function, we isolated the recessive lethal mutant heartstrings, which lacks pectoral fins and exhibits severe cardiac dysfunction, beginning with a slow heart rate and progressing to a stretched, non-functional heart. We mapped and cloned the heartstrings mutation and find it to encode the zebrafish ortholog of the TBX5 gene. The heartstrings mutation causes premature termination at amino acid 316. Homozygous mutant embryos never develop pectoral fin buds and do not express several markers of early fin differentiation. The total absence of any fin bud differentiation distinguishes heartstrings from most other mutations that affect zebrafish fin development, suggesting that Tbx5 functions very early in the pectoral fin induction pathway. Moderate reduction of Tbx5 by morpholino causes fin malformations, revealing an additional early requirement for Tbx5 in coordinating the axes of fin outgrowth. The heart of heartstrings mutant embryos appears to form and function normally through the early heart tube stage, manifesting only a slight bradycardia compared with wild-type siblings. However, the heart fails to loop and then progressively deteriorates, a process affecting the ventricle as well as the atrium. Relative to mammals, fish require lower levels of Tbx5 to produce malformed appendages and display whole-heart rather than atrial-predominant cardiac defects. However, the syndromic deficiencies of tbx5 mutation are remarkably well retained between fish and mammals.

    2005-04-01

    Full Text Available Com o objetivo de discutir a sexualidade de adolescentes com deficiência mental e as repercussões familiares do adolescer, realizou-se uma revisão bibliográfica a partir da base de dados da Bireme, analisando a produção de 1990 a 2003 sobre o tema. Os artigos mostram que os pais se deparam com novos desafios para a integração social dos seus filhos com deficiência mental quando estes chegam à adolescência, especialmente com o despertar de sua sexualidade genital. Os trabalhos corroboram que os preconceitos no campo da sexualidade ainda estão presentes. Fica evidente o temor diante das manifestações sexuais desses adolescentes, como a masturbação, e a dificuldade dos pais em lidar com a situação. Pelo receio do abuso sexual e da gravidez decorrente, métodos contraceptivos, inclusive a esterilização, são discutidos. A revisão da literatura indica, enfim, que o desenvolvimento da sexualidade se dá igualmente nos adolescentes com e sem deficiência, mas são atribuídas representações distintas aos dois grupos. Conclui-se que a ampliação do debate aos pais e adolescentes com deficiência pode contribuir para que eles tenham uma vivência da sexualidade com menos estigmas, menos exposta a riscos e, conseqüentemente, mais satisfatória.The objective of this article is to discuss the sexuality of the mentally retarded adolescent and its consequences within the family. It is based on articles from Bireme, written from 1990 to 2003, related to the sexuality of the adolescents with intellectual disability, as well as the impacts of the adolescence period on the family. The articles show that during this period of development, the parents of the adolescents with intellectual disability face challenges regarding their children's social integration, with the genital sexual awakening being of greatest concern. The papers reinforce that there is still a great deal of prejudice regarding sexuality. It is also clear that parents are

    We report the case of a 48-year-old Japanese man who suffered from Marfan syndrome with severe aortic regurgitation, mitral regurgitation and rapid atrial fibrillation, which were aggravated by hyperdynamic circulatory conditions associated with coexistent Basedow's disease. Furthermore, concurrence of Arg353Gln polymorphism-related factor VII deficiency was discovered at the preoperative assessments. Both of his two brothers suffered from Marfan syndrome; however they had no findings of Arg353Glu polymorphism-related factor VII deficiency or Basedow's disease. After normalization of thyroid function, he had successfully the operations of Bentall procedure: a composite prosthetic graft: replacement of both the ascending aorta and aortic valve, and mitral valve annuloplasty. No specific therapy such as fresh frozen plasma or factor VII replacement therapy was required. He completely returned to his business work 6 weeks after the operation. Concurrence of Marfan syndrome and factor VII deficiency induced by two-hit genomic abnormalities and furthermore Basedow's disease, which significantly compromised the pathophysiological condition of Marfan syndrome, is extremely rare.

  20. Monitoring and prevalence rates of metabolic syndrome in military veterans with serious mental illness.

    Directory of Open Access Journals (Sweden)

    Sameed Ahmed M Khatana

    Full Text Available BACKGROUND: Cardiovascular disease is the leading cause of mortality among patients with serious mental illness (SMI and the prevalence of metabolic syndrome--a constellation of cardiovascular risk factors--is significantly higher in these patients than in the general population. Metabolic monitoring among patients using second generation antipsychotics (SGAs--a risk factor for metabolic syndrome--has been shown to be inadequate despite the release of several guidelines. However, patients with SMI have several factors independent of medication use that predispose them to a higher prevalence of metabolic syndrome. Our study therefore examines monitoring and prevalence of metabolic syndrome in patients with SMI, including those not using SGAs. METHODS AND FINDINGS: We retrospectively identified all patients treated at a Veterans Affairs Medical Center with diagnoses of schizophrenia, schizoaffective disorder or bipolar disorder during 2005-2006 and obtained demographic and clinical data. Incomplete monitoring of metabolic syndrome was defined as being unable to determine the status of at least one of the syndrome components. Of the 1,401 patients included (bipolar disorder: 822; schizophrenia: 222; and schizoaffective disorder: 357, 21.4% were incompletely monitored. Only 54.8% of patients who were not prescribed SGAs and did not have previous diagnoses of hypertension or hypercholesterolemia were monitored for all metabolic syndrome components compared to 92.4% of patients who had all three of these characteristics. Among patients monitored for metabolic syndrome completely, age-adjusted prevalence of the syndrome was 48.4%, with no significant difference between the three psychiatric groups. CONCLUSIONS: Only one half of patients with SMI not using SGAs or previously diagnosed with hypertension and hypercholesterolemia were completely monitored for metabolic syndrome components compared to greater than 90% of those with these characteristics

    Pneumonia is the leading cause of death after acute spinal cord injury and is associated with poor neurological outcome. In contrast to the current understanding, attributing enhanced infection susceptibility solely to the patient's environment and motor dysfunction, we investigate whether a secondary functional neurogenic immune deficiency (spinal cord injury-induced immune deficiency syndrome, SCI-IDS) may account for the enhanced infection susceptibility. We applied a clinically relevant model of experimental induced pneumonia to investigate whether the systemic SCI-IDS is functional sufficient to cause pneumonia dependent on spinal cord injury lesion level and investigated whether findings are mirrored in a large prospective cohort study after human spinal cord injury. In a mouse model of inducible pneumonia, high thoracic lesions that interrupt sympathetic innervation to major immune organs, but not low thoracic lesions, significantly increased bacterial load in lungs. The ability to clear the bacterial load from the lung remained preserved in sham animals. Propagated immune susceptibility depended on injury of central pre-ganglionic but not peripheral postganglionic sympathetic innervation to the spleen. Thoracic spinal cord injury level was confirmed as an independent increased risk factor of pneumonia in patients after motor complete spinal cord injury (odds ratio = 1.35, P spinal cord injury directly causes increased risk for bacterial infection in mice as well as in patients. Besides obvious motor and sensory paralysis, spinal cord injury also induces a functional SCI-IDS ('immune paralysis'), sufficient to propagate clinically relevant infection in an injury level dependent manner. © The Author (2016).

    Patients with mental illnesses have been found to shorter life expectancy due to an increased risk of heart disease. Some medication used to treat mental illnesses have been linked to weight gain and other physical change that make patients susceptible to heart disease. In order to reduce this risk it is important that health professionals regularly measure and monitor signs of these physical changes. This research has found that measuring both waist circumference and blood pressure of patients is a safe and reliable way to way to monitor patients. To identify if combined blood pressure and waist circumference measurements are reliable predictor of metabolic syndrome, a descriptive correlational design was used to examine the sensitivity and specificity of screening techniques used to detect metabolic syndrome. Data were collected regarding waist circumference, body mass index, blood pressure, fasting blood glucose, triglycerides and high-density lipoproteins. Blood pressure and waist circumference measurements demonstrated high significance, sensitivity and specificity as screening instruments for metabolic syndrome. Combined waist circumference and blood pressure measurements may be clinically useful for a quick and reliable detection of metabolic syndrome in patients with addiction and comorbid mental health problems. © 2014 John Wiley & Sons Ltd.

    Dent disease is an X-linked recessive disorder affecting the proximal tubule and is characterized by low-molecular-weight proteinuria (LMWP), hypercalciuria, nephrocalcinosis/nephrolithiasis with a variable number of features of Fanconi syndrome. It is most often associated with mutations in CLCN5, which encodes the endosomal electrogenic chloride/proton exchanger ClC-5. Renal acidification abnormalities are only rarely seen in Dent disease, whereas the hypokalemic metabolic alkalosis associated with hyperreninemic hyperaldosteronism (Bartter-like syndrome) has been reported in only one patient so far. We report on a 5-year-old boy with Dent disease caused by mutation in CLCN5 gene, c.1073G>A, who presented with hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism persisting over the entire follow-up. No mutations were found in NKCC2, ROMK, NCCT, or ClC-Kb genes. In addition, the patient exhibited growth failure associated with partial growth hormone (GH) deficiency. Coexistence of Bartter-like syndrome features with LMWP should prompt a clinician to search for Dent disease. The Bartter syndrome phenotype seen in Dent disease patients may represent a distinct form of Bartter syndrome, the exact mechanism of which has yet to be fully elucidated. Growth delay that persists in spite of appropriate therapy should raise suspicion of other causes, such as GH deficiency.

    Bartter syndrome (BS) is a disorder with normotensive hypokalemic alkalosis and hyperreninemic hyperaldosteronemia. BS affects infants or early childhood. Patients with BS type 3 harbor mutation in CLCNKB, Cl channel Kb. Gitelman syndrome (GS) is a disorder in childhood, with mutation in SLC12A3. Isolated adrenocorticotropin deficiency (IAD) causes secondary adrenal insufficiency. Neither elderly cases, nor cases with IAD were previously reported in BS. A 72-year-old man was admitted with acute adrenal crisis. He had been treated for IAD for 19 years. He had no trouble during perinatal period, delivery, and growth. After the recovery from adrenal crisis, laboratory tests revealed hypokalemia; 3.0 mEq/L (normal: 3.5-4.5), impaired renal function: eGFR; 37.6 mL/min/1.73 m2, normomagnesemia; 2.1 mg/dL (1.7-2.3), hyperreninemia; 59.4 ng/mL/h (0.2-2.7), hyperaldosteronemia; 23.5 ng/dL (3.0-15.9), and normal urinary ratio of calcium/creatinine. In diuretic tests, he showed a fine response to furosemide, and a mild response to thiazide. In genetic tests, no mutation of SLC12A3 was found and homozygous mutation: c.1830 G > A in CLCNKB was shown. Thus he was diagnosed as BS type 3. Current case presented with unusual features as BS type 3, 1) his late and mild clinical manifestation suggested GS rather than BS, 2) laboratory data and diuretics tests did not show typical features as BS, and 3) IAD and chronic renal failure altered electrolyte metabolism. In conclusion, current case implies that BS type 3 should be considered even in elderly cases with normotensive hypokalemia, and highlights importance of endocrinological and genetic examinations.

    Full Text Available OBJECTIVE: To determine the frequency of obstructive sleep apnea syndrome (OSAS, metabolic syndrome and common mental disorders in the working population of 11 small enterprises and the feasibility of a program of action for health. METHOD: The clinical risk of OSAS, the prevalence of metabolic syndrome, and the level of psychological disorders were assessed during routine medical examination at the workplace in 2012. The response to medical advice was assessed in 2013. RESULTS: 12.3% of the workers were suspected of being affected by OSAS. One or more components of metabolic syndrome were present in 24.5% of cases. OSAS in "healthy" workers was significantly associated with the presence of one or more components of metabolic syndrome (OR = 3.83; 95%CI 1.45-10.13 and with a psychological disorders score in the highest quartile (OR = 4.67; 95%CI = 1.72-12.64. Workers with suspected OSAS were reluctant to follow advice about undergoing further tests under the NHS. However, in some cases, confirmation of the OSAS diagnosis and subsequent treatment led to an improvement in metabolic condition. CONCLUSION: Although participation in treatment was limited, anecdotal cases support the idea that prevention of obstructive sleep apnea in the workplace might be useful for workers' health.

    Our goal was to investigate the physical and mental health of mothers who care for a child with Rett syndrome. We assessed maternal physical and mental health by using the SF-12 version 1 physical component summary and mental component summary scores as the outcome measures of interest. Mothers (n = 135) of children with Rett syndrome completed the SF-12 measure as part of the Australian Rett Syndrome Study in 2002. The analysis investigated linear relationships between physical and mental health scores and maternal, family, and child characteristics. Mothers ranged in age from 21 to 60 years and their children from 3 to 27 years. Nearly half of these mothers (47.4%) indicated that they worked full-time or part-time outside the home, and 41% had a combined family (gross) income of health demonstrated that the following factors were positively associated with better maternal physical health: the mother working full-time or part-time outside the home, having some high school education, having private health insurance, the child not having breathing problems in the last 2 years, the child not having home-based structured therapy, and high scores on the Family Resource Scale (indicating adequacy of time resources for basic and family needs). The resultant model for mental health demonstrated that the following factors were positively associated with better maternal mental health: the mother working full-time or part-time outside the home, the child not having a fracture in the last 2 years, lesser reporting of facial stereotypes and involuntary facial movements, being in a well-adjusted marriage, and having low stress scores. Our study suggests that the most important predictors of maternal physical and emotional health are child behavior, caregiver demands, and family function.

    In this study, we investigated the effects of GH treatment in children with Down syndrome who had been diagnosed with GH deficiency (GHD). A total of 20 subjects were investigated in this study. Fourteen Down syndrome children (5 boys and 9 girls) with short stature due to GHD were treated with GH at Okayama Red Cross General Hospital, and 6 Down syndrome children (4 boys and 2 girls) with short stature due to GHD were registered in the Pfizer International Growth Database (KIGS). Height SD score (SDS) increased throughout the three-year GH treatment period. The overall mean height SDS increased from -3.5 at baseline to -2.5 after 3 yr of treatment. The mean change in height SDS during these 3 yr was 1.1. In addition, height assessment of SD score based on Down syndrome-specific growth data in the Japanese population revealed that the height SDS (Down syndrome) also increased across the 3-yr GH treatment period. The mean change in height SDS (Down syndrome) during these three years was 1.3. GH therapy was effective for Down syndrome short stature accompanied by GHD, and no new safety concerns were found in this study.

    This work gives comprehensive information about new recessively inherited syndrome characterized by development of childhood malignancies. Behind this new described syndrome, called Constitutional mismatch repair-deficiency syndrome (CMMR-D), there are biallelic mutations in genes, which cause adult cancer syndrom termed Lynch syndrom (Hereditary non-polyposis cancer syndrom-HNPCC) if they are heterozygous mutations. Biallelic germline mutations of genes MLH1, MSH2, MSH6 and PMS2 in CMMR-D are characterized by increased risk of hematological malignancies, atypical brain tumors and early onset of colorectal cancers. An accompanying manifestation of the disease are skin spots with diffuse margins and irregular pigmentation reminiscent of Café au lait spots of NF1. This paper reports a case of a family with CMMR-D caused by novel homozygous MSH6 mutations leading to gliomatosis cerebri, T-ALL in an 11-year-old female and glioblastoma multiforme in her 10-year-old brother, both with rapid progression of the diseases. A literature review of brain tumors in CMMR-D families shows that they are treatment-resistant and lead to early death. Therefore, this work highlights the importance of early identification of patients with CMMR-D syndrome - in terms of initiation of a screening program for early detection of malignancies as well as early surgical intervention.

    The landscape of hereditary syndromes and clinicopathologic characteristics among US Latino/Hispanic individuals with colorectal cancer (CRC) remains poorly understood. A total of 265 patients with CRC who were enrolled in the Hispanic Colorectal Cancer Study were included in the current study. Information regarding CRC risk factors was elicited through interviews, and treatment and survival data were abstracted from clinical charts. Tumor studies and germline genetic testing results were collected from medical records or performed using standard molecular methods. The mean age of the patients at the time of diagnosis was 53.7 years (standard deviation, 10.3 years), and 48.3% were female. Overall, 21.2% of patients reported a first-degree or second-degree relative with CRC; 3.4% met Amsterdam I/II criteria. With respect to Bethesda guidelines, 38.5% of patients met at least 1 criterion. Of the 161 individuals who had immunohistochemistry and/or microsatellite instability testing performed, 21 (13.0%) had mismatch repair (MMR)-deficient (dMMR) tumors. dMMR tumors were associated with female sex (61.9%), earlier age at the time of diagnosis (50.4 ± 12.4 years), proximal location (61.9%), and first-degree (23.8%) or second-degree (9.5%) family history of CRC. Among individuals with dMMR tumors, 13 (61.9%) had a germline MMR mutation (MutL homolog 1 [MLH1] in 6 patients; MutS homolog 2 [MSH2] in 4 patients; MutS homolog 6 [MHS6] in 2 patients; and PMS1 homolog 2, mismatch repair system component [PMS2] in 1 patient). The authors identified 2 additional MLH1 mutation carriers by genetic testing who had not received immunohistochemistry/microsatellite instability testing. In total, 5.7% of the entire cohort were confirmed to have Lynch syndrome. In addition, 6 individuals (2.3%) had a polyposis phenotype. The percentage of dMMR tumors noted among Latino individuals (13%) is similar to estimates in non-Hispanic white individuals. In the current study, the majority of

    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.

    We assessed the molecular characteristics and the frequency of mutations in mismatch-repair genes among Bedouin patients with colorectal cancer (CRC) in Israel. Bedouin patients with a diagnosis of CRC at a major hospital in the southern part of Israel were deemed eligible for this study. The primary screening method was immunohistochemical staining for mismatch-repair proteins (MLH1, MSH2, MSH6, and PMS2). For subjects with abnormal immunohistochemical staining, we performed microsatellite instability (MSI) analyses, and for tumors with a loss of MLH1 expression we also performed BRAF testing. In MSI high cases we searched further for germline mutations. Of the 24 patients enrolled, four subjects (16.7%) had MSI high tumors: one subject was found to harbor a biallelic PMS2 mutation, one subject had Lynch syndrome (LS) with MSH6 mutation and two subjects had a loss of MLH1/PMS2 proteins/BRAF wild type /normal MLH1 sequence. Ten patients (41.7%) were younger than 50 at the time of diagnosis and none had first degree relatives with CRC. In conclusion, in this cohort of 24 consecutive Arab Bedouins with CRC, one patient was found to harbor a constitutional mismatch repair deficiency, one patient had LS with MSH6 mutation, and two patients had unresolved loss of MLH1/PMS2 proteins/BRAF wild type phenotype.

    Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

    Addiction is a substantial health issue with limited treatment options approved by the FDA and as such currently available. The advent of neuroimaging techniques that link neurochemical and neurogenetic mechanisms to the reward circuitry brain function provides a framework for potential genomic-based therapies. Through candidate and genome-wide association studies approaches, many gene polymorphisms and clusters have been implicated in drug, food and behavioral dependence linked by the common rubric reward deficiency syndrome (RDS). The results of selective studies that include the role of epigenetics, noncoding micro RNAs in RDS behaviors especially drug abuse involving alcohol, opioids, cocaine, nicotine, pain and feeding are reviewed in this article. New targets for addiction treatment and relapse prevention, treatment alternatives such as gene therapy in animal models, and pharmacogenomics and nutrigenomics methods to manipulate transcription and gene expression are explored. The recognition of the clinical benefit of early genetic testing to determine addiction risk stratification and dopaminergic agonistic, rather than antagonistic therapies are potentially the genomic-based wave of the future. In addition, further development, especially in gene transfer work and viral vector identification, could make gene therapy for RDS a possibility in the future.

    It has been suggested that vitamin D influences the immunoregulation and subsequently affects the risk for conversion of clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (MS). There is little information regarding the relationship between levels of vitamin D and CIS conversion to MS in Egyptian patients. It is to study contribution of vitamin D deficiency to conversion of CIS to clinically definite multiple sclerosis (CDMS) and correlation of vitamin D level to cognitive and magnetic resonance imaging (MRI) results. A longitudinal prospective case control study was conducted on 43 Egyptian patients diagnosed as CIS according to McDonald criteria (2010). Clinical presentation, brain MRI and 25-hydroxyvitamin D levels were evaluated at baseline and after one-year follow-up. The CIS patients that converted to MS showed significant lower vitamin D level (p < 0.001) than the non-convertors. Multivariate logistic regression analysis revealed that the CIS patients with lower 25-hydroxyvitamin D level (p < 0.001) are at higher risk for early conversion to MS. There was a significant positive correlation between the vitamin D level and PASAT (r = 0.36, p = 0.02). It was found that there was a significant negative correlation between vitamin D level and MRI T 2 load (r = -0.38, p = 0.01). The low level of 25-hydroxyvitamin D may predict early conversion to clinically definite MS. Early vitamin D supplementation is recommended in patients with CIS.

    Wolfram syndrome 1 is a rare autosomal recessive neurodegenerative disease characterized by diabetes insipidus, diabetes mellitus, optic atrophy, and deafness. Mutations in the WFS1 gene encoding the wolframin glycoprotein can lead to endoplasmic reticulum stress and unfolded protein responses in cells, but the pathophysiology at whole organism level is poorly understood. In this study, several organs (heart, liver, kidneys, and pancreas) and bodily fluids (trunk blood and urine) of 2- and 6-month old Wfs1 knockout (KO), heterozygote (HZ), and wild-type (WT) mice were analyzed by untargeted and targeted metabolomics using liquid chromatography-mass spectrometry. The key findings were significant perturbations in the metabolism of pancreas and heart before the onset of related clinical signs such as glycosuria that precedes hyperglycemia and thus implies a kidney dysfunction before the onset of classical diabetic nephropathy. The glucose use and gluconeogenesis in KO mice are intensified in early stages, but later the energetic needs are mainly covered by lipolysis. Furthermore, in young mice liver and trunk blood hypouricemia, which in time turns to hyperuricemia, was detected. In summary, we show that the metabolism in Wfs1-deficient mice markedly differs from the metabolism of WT mice in many aspects and discuss the future biological and clinical relevance of these observations.

    Studies on fragile X syndrome are scarce in Saudi Arabia and othercountries of the Arabian Peninsula. The few studies previously done haveeither been in the form of case reports or those performed oninstitutionalized mentally retarded patients. The aim of this study was todetermine the prevalence of fragile X syndrome among cases with mentalretardation who have been referred to the pediatric neurology clinics of KingKhalid University Hospital (KKUH) in Riyadh. Cytogenetic studies wereperformed in 94 cases that were referred to the pediatric neurology clinicsof KKUH because of mental retardation and/or delayed milestones ofdevelopment, from July 1995 to December 1997. Six male probands (6.4%) showedthe classic fragile X chromosome and another six (including a four year oldgirl) were detected, following extension of the cytogenetic studies to all 32first-degree relatives. Affection of more than one sibling was ascertained infour families. One family had four brothers with fragile X syndrome, whereasanother formed part of a large kindred with twelve males and five females whowere mentally retarded. A clinical, physical and psychological screeningchecklist was applied to the eleven affected males. Large testicular size,long face and short attention span were the most frequent features and eachwas detected in nine patients (82%). Pes planus and history of delayed speechwere found in eight patients (73%). The study showed that the fragile Xsyndrome clinical screening checklist has been applied in other populationsmight equally valuable and applicable among the population of Saudi Arabia.However, the presence of pale blue eyes can be excluded and more weight givento positive family history of mental to the most common clinical diagnosticfeatures of fragile X syndrome.

    To investigate the distribution of abnormal hilit syndromes in traditional Uighur medicine (TUM) among human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) patients, and to find out the clinical characteristics of abnormal savda syndrome type HIV/AIDS patients. Between June and July in 2012, 307 eligible HIV/AIDS patients from in-patient department and out-patient clinics of Xinjiang Uighur Autonomous Region the Sixth People's Hospital in Urumqi were investigated. TUM syndrome differentiation was performed by a senior TUM physician. Each participant completed a Sign and Symptom Check-List for Persons Living with HIV/AIDS (SSC-HIV) questionnaire. Depression was evaluated by using Hamilton Rating Scale for Depression Questionnaire. Blood specimen was collected from each participant to test the levels of blood chemicals. Of 307 HIV/AIDS patients, 189 (61.6%) were abnormal savda syndrome type, 118 (38.4%) were non-abnormal-savda syndrome type. Mean CD4 counts of abnormal savda syndrome type patients was (227.61±192.93) cells/µL, and the prevalence of anemia, thrombocytopenia, and elevated cystatin C were 49.7%, 28.6%, and 44.7%, which were significantly higher than those in the non-abnormal-savda syndrome type patients (26.3%, 16.0% and 25.0%,PHIV/AIDS-related symptoms such as fatigue (42.3%), back aches (40.7%), lack of appetite (33.9%), night sweats (31.7%) were more common among abnormal savda syndrome patients (PHIV/AIDS patients, and they present a more sever clinical manifestation.

    Previous studies suggest that adults with Tourette syndrome (TS) can respond unconventionally on tasks involving social cognition. We therefore hypothesized that these patients would exhibit different neural responses to healthy controls in response to emotionally salient expressions of human eyes. Twenty-five adults with TS and 25 matched healthy controls were scanned using fMRI during the standard version of the Reading the Mind in the Eyes Task which requires mental state judgements, and a novel comparison version requiring judgements about age. During prompted mental state recognition, greater activity was apparent in TS within left orbitofrontal cortex, posterior cingulate, right amygdala and right temporo-parietal junction (TPJ), while reduced activity was apparent in regions including left inferior parietal cortex. Age judgement elicited greater activity in TS within precuneus, medial prefrontal and temporal regions involved in mentalizing. The interaction between group and task revealed differential activity in areas including right inferior frontal gyrus. Task-related activity in the TPJ covaried with global ratings of the urge to tic. While recognizing mental states, adults with TS exhibit greater activity than controls in brain areas involved in the processing of negative emotion, in addition to reduced activity in regions associated with the attribution of agency. In addition, increased recruitment of areas involved in mental state reasoning is apparent in these patients when mentalizing is not a task requirement. Our findings highlight differential neural reactivity in response to emotive social cues in TS, which may interact with tic expression.

    One family (3 cases) with the Kenny syndrome and a second family (3 cases) with features of Kenny syndrome but lacking medullary stenosis are reported. The main symptoms in both families are proportionate dwarfism, cortical thickening of tubular bones, variable anomalies of the calvaria, anemia, transient hypoparathyroidism and variable ocular anomalies. The latter include microphthalmia, and moderate-to-severe myopia or hyperopia. In the first family there was medullary stenosis of most tubular bones. In the second family two cases exhibited mild-to-moderate cortical thickening of tubular bones, but absent or mild medullary stenosis. Possible variability of the Kenny syndrome is discussed. Endocrine studies failed to demonstrate any permanent disturbance of parathormone or calcitonin metabolism, or GH deficiency. Pathogenesis remains unclear. Autosomal dominant inheritance seems to be likely.

    To identify predictors of burnout syndrome, such as job satisfaction and manifestations of occupational stress, in mental health workers. The study included a snowball sample of 174 mental health workers in Croatia. The following measurement instruments were used: Maslach Burnout Inventory, Manifestations of Occupational Stress Survey, and Job Satisfaction Survey. We correlated dimensions of burnout syndrome with job satisfaction and manifestations of occupational stress dimensions. We also performed multiple regression analysis using three dimensions of burnout syndrome--emotional exhaustion, depersonalization, and personal accomplishment. Stepwise multiple regression analysis showed that pay and rewards satisfaction (beta=-0.37), work climate (beta=-0.18), advancement opportunities (beta=0.17), the degree of psychological (beta=0.41), and physical manifestations of occupational stress (beta=0.29) were significant predictors of emotional exhaustion (R=0.76; F=30.02; Ppay and rewards satisfaction (beta=0.22) were significant predictors of depersonalization (R=0.57; F=13,01; PSatisfaction with the work climate (beta=-0.20) was a significant predictor of lower levels of personal accomplishment (R=0.20; F=5.06; Pjob satisfaction and manifestations of occupational stress proved to be relevant predictors of burnout syndrome.

    The human primary carnitine deficiency syndromes are potentially fatal disorders affecting children and adults. The molecular etiologies of these syndromes have not been determined. In this investigation, we considered the hypothesis that these syndromes result from defective transport of carnitine into tissues, particularly skeletal muscle. The problem was approached by mathematical modeling, by using the technique of kinetic compartmental analysis. A tracer dose of L-[methyl-3H]carnitine was administered intravenously to six normal subjects, one patient with primary muscle carnitine deficiency (MCD), and four patients with primary systemic carnitine deficiency (SCD). Specific radioactivity was followed in plasma for 28 d. A three-compartment model (extracellular fluid, muscle, and ''other tissues'') was adopted. Rate constants, fluxes, pool sizes, and turnover times were calculated. Results of these calculations indicated reduced transport of carnitine into muscle in both forms of primary carnitine deficiency. However, in SCD, the reduced rate of carnitine transport was attributed to reduced plasma carnitine concentration. In MCD, the results are consistent with an intrinsic defect in the transport process. Abnormal fluctuations of the plasma carnitine, but of a different form, occurred in MCD and SCD. The significance of these are unclear, but in SCD they suggest abnormal regulation of the muscle/plasma carnitine concentration gradient. In 8 of 11 subjects, carnitine excretion was less than dietary carnitine intake. Carnitine excretion rates calculated by kinetic compartmental analysis were higher than corresponding rates measured directly, indicating degradation of carnitine. However, we found no radioactive metabolites of L-[methyl-3H]carnitine in urine. These observations suggest that dietary carnitine was metabolized in the gastrointestinal tract

    Transition from at-risk state to full syndromal mental disorders is underexplored for unipolar and bipolar disorders compared with psychosis. Prospective, trans-diagnostic study of rates and predictors of early transition from sub-threshold to full syndromal mental disorder. One-year outcome of 243 consenting youth aged 15-25 years with a sub-syndromal presentation of a potentially severe mental disorder. Survival analysis and odds ratio (OR) for predictors of transition identified from baseline clinical and demographic ratings. About 17% ( n =36) experienced transition to a major mental disorder. Independent of syndromal diagnosis, transition was significantly more likely in individuals who were NEET (not in education, employment or training), in females and in those with more negative psychological symptoms (e.g. social withdrawal). NEET status and negative symptoms are modifiable predictors of illness trajectory across diagnostic categories and are not specific to transition to psychosis.

    Recollection of previously experienced events is a key element of human memory that entails recovery of spatial, perceptual, and mental state details. While deficits in this capacity in association with brain disease have serious functional consequences, little is known about individual differences in autobiographical memory (AM) in healthy individuals. Recently, healthy adults with highly superior autobiographical capacities have been identified (e.g., LePort, A.K., Mattfeld, A.T., Dickinson-Anson, H., Fallon, J.H., Stark, C.E., Kruggel, F., McGaugh, J.L., 2012. Behavioral and neuroanatomical investigation of Highly Superior Autobiographical Memory (HSAM). Neurobiol. Learn. Mem. 98(1), 78-92. doi: 10.1016/j.nlm.2012.05.002). Here we report data from three healthy, high functioning adults with the reverse pattern: lifelong severely deficient autobiographical memory (SDAM) with otherwise preserved cognitive function. Their self-reported selective inability to vividly recollect personally experienced events from a first-person perspective was corroborated by absence of functional magnetic resonance imaging (fMRI) and event-related potential (ERP) biomarkers associated with naturalistic and laboratory episodic recollection, as well as by behavioral evidence of impaired episodic retrieval, particularly for visual information. Yet learning and memory were otherwise intact, as long as these tasks could be accomplished by non-episodic processes. Thus these individuals function normally in day-to-day life, even though their past is experienced in the absence of recollection. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    In an attempt to resolve controversy regarding the causal contributions of mesolimbic dopamine (DA) systems to reward, we evaluate the three main competing explanatory categories: "liking,"learning," and "wanting" [1]. That is, DA may mediate (a) the hedonic impact of reward (liking), (b) learned predictions about rewarding effects (learning), or (c) the pursuit of rewards by attributing incentive salience to reward-related stimuli (wanting). We evaluate these hypotheses, especially as they relate to the Reward Deficiency Syndrome (RDS), and we find that the incentive salience or "wanting" hypothesis of DA function is supported by a majority of the evidence. Neuroimaging studies have shown that drugs of abuse, palatable foods, and anticipated behaviors such as sex and gaming affect brain regions involving reward circuitry, and may not be unidirectional. Drugs of abuse enhance DA signaling and sensitize mesolimbic mechanisms that evolved to attribute incentive salience to rewards. Addictive drugs have in common that they are voluntarily selfadministered, they enhance (directly or indirectly) dopaminergic synaptic function in the nucleus accumbens (NAC), and they stimulate the functioning of brain reward circuitry (producing the "high" that drug users seek). Although originally believed simply to encode the set point of hedonic tone, these circuits now are believed to be functionally more complex, also encoding attention, reward expectancy, disconfirmation of reward expectancy, and incentive motivation. Elevated stress levels, together with polymorphisms of dopaminergic genes and other neurotransmitter genetic variants, may have a cumulative effect on vulnerability to addiction. The RDS model of etiology holds very well for a variety of chemical and behavioral addictions.

    Glucose transporter type 1 deficiency syndrome (GLUT1-DS) is caused by a defect in glucose transport across the blood-brain barrier. The main symptoms are epilepsy, developmental delay, movement disorders, and deceleration of head circumference. A ketogenic diet has been shown to be effective in controlling epilepsy in GLUT1-DS. We report a female child (3 y 4 mo) who presented with delayed psychomotor development and frequent episodes of staggering, impaired vigilance, and vomiting that resolved promptly after food intake. Electroencephalography was normal. The cerebrospinal fluid-blood glucose ratio was 0.42 (normal ≥ 0.45). GLUT1-DS was confirmed by molecular genetic testing, which showed a novel de novo heterozygous mutation in the SLC2A1 gene (c.497_499delTCG, p.VAL166del). Before starting a ketogenic diet, the child's cognitive development was tested using the Snijders-Oomen Non-Verbal Intelligence Test, which revealed a heterogeneous intelligence profile with deficits in her visuomotor skills and spatial awareness. Her motor development was delayed. Three months after introducing a ketogenic diet, she showed marked improvement in speech and motor development, as tested by the Movement Assessment Battery for Children (manual dexterity 16th centile, ball skills 1st centile, static and dynamic balance 5th centile). This case demonstrates that GLUT1-DS should be investigated in individuals with unexplained developmental delay. Epilepsy is not a mandatory symptom. The ketogenic diet is also beneficial for non-epileptic symptoms in GLUT1-DS. © The Authors. Developmental Medicine & Child Neurology © 2011 Mac Keith Press.

    To report on a clinical practice series of testosterone-replacement therapy (TRT) in men with testosterone deficiency syndrome (TDS), examining clinical efficacy, biochemical parameters and effects on prostate health over a 2-year period. A retrospective review of 85 patients with symptoms of TDS and at least a 3-month trial of TRT was performed in this single-centre, clinical practice setting. Three domains of symptomatology were evaluated: libido, erectile function and energy levels. Symptoms were assessed by a combination of patient reporting, physician's assessment and validated symptom assessment scores. Total testosterone (TT), calculated bio-available testosterone (BT) and prostate-specific antigen (PSA) levels were continuously measured and effects on prostate health were examined. Only 38 (45%) patients in this cohort remained on TRT for >2 years. The most common reason for discontinuing treatment was lack of clinical response but those remaining on TRT had continued improvement in libido, erectile function and energy levels. During treatment, the average TT and calculated BT values significantly increased compared with the baseline values at most of the evaluated time points, with no significant change in average PSA values. In all, 15% of this cohort had some degree of progression of lower urinary tract symptoms. Seven patients had eight 'for-cause' prostate biopsies either during supplementation or at any date after completion, with an only three positive for cancer. Only 45% of men on TRT remained on treatment for >2 years in this clinical practice experience of men with TDS. Those remaining showed persistent improvement in their symptoms. The average TT and BT values increased significantly with no significant change in PSA levels.

    People with acquired immune deficiency syndrome (AIDS) develop ischemic stroke through distinct mechanisms. These include infections such as syphilis, tuberculosis, varicella, and other conditions such as cocaine abuse, endocarditis, and hypercoagulability. The effect of improved awareness, detection, and treatment with highly active antiretroviral therapy (HAART) on the incidence and outcome of AIDS patients with stroke is unknown. Data from the Nationwide Inpatient Sample from 1995 to 2010 were analyzed. Patients with ischemic stroke and AIDS were identified using ICD-9 (International Classification of Diseases) codes. Time trends for demographics, survival, and frequency of AIDS-associated conditions were analyzed. Proportion of AIDS among stroke patients increased significantly during the study. Median age of all strokes decreased from 75 years in 1995 to 72 years in 2010. Conversely, median age for men with stroke and AIDS increased from 43 years to 53 years; and for women with stroke and AIDS, from 41 years to 51 years. Death rates from stroke in the AIDS patients declined. In recent years, the death rates from stroke are similar to patients without HIV/AIDS. Stroke patients with AIDS had increased odds of syphilis (odds ratio [OR]: 33.50), varicella (OR: 48.34), tuberculosis (OR: 137.48), endocarditis (OR: 5.19), cocaine abuse (OR: 26.05), and hypercoagulability (OR: 4.82). In the HAART era, the median age of incident stroke in AIDS has increased and the mortality from stroke has improved. Research should focus on optimal management of dyslipidemia while on HAART. Whether HAART can reduce the incidence and improve survival of stroke needs to be explored. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Objective: To investigate the imaging findings with pathologic correlation in patients with acquired immune deficiency syndrome (AIDS). Methods: Imaging findings, autopsy and pathological data were retrospectively analyzed in eight patients with AIDS. Routine CT scanning of different body parts was performed during their hospitalization. CT scanning was performed from the skull to the pelvis immediately following their death. After routine formalin fixing, 7 cadavers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each sections and organs for pathological examinations. Results: The autopsy data showed parasitic infections (5 cases), bacterial infections (3 cases), fungal infections (2 cases), virus infections (2 cases), lymphoma (1 case) and cerebrovascular diseases (1 case)in eight patients with AIDS. The CT scanning demonstrated symmetrical ground glass liked shadows with pulmonary hilus as the center in 5 cases of pulmonary PCP infection; pulmonary patchy shadows, scattering distribution of nodular shadows, extensive military nodular shadows with even distribution and tuberculous pleurisy; cloudy shadows for 2 cases of fungi infection with multiple foci of chronic inflammation; pulmonary net-like parenchymal changes for 2 cases of pulmonary CMV infection; thickened intestinal wall and narrowed intestinal lumen for 1 case of intestinal tumor; low density shadows of brain tissue for 1 case of CMV encephalitis and MRI findings of high T 1 and high T 2 signals as well as MRA findings of broken vascular channels in liquefied areas of brain tissues; patchy low density areas inside a cyst of brain for one case of brain toxoplasmosis infection; multiple small patchy low density areas in cerebral basal ganglia for one case of brain cryptococcus infection. Conclusions: In AIDS patients, infection and tumor may occur in various organs resulting in complex symptoms, which makes it more complicated and difficult to make

  17. Physicians' obligations to patients infected with Ebola: echoes of acquired immune deficiency syndrome.

    Physicians across the United States are engaged in training in the identification, isolation, and initial care of patients with Ebola. Some will be asked to do more. The issue this viewpoint will address is the moral obligation of physicians to participate in these activities. In order to do so the implicit contract between society and its physicians will be considered, as will many of the arguments that are redolent of those that were litigated 30 years ago when acquired immune deficiency syndrome (AIDS) was raising public fears to similar levels, and some physicians were publically proclaiming their unwillingness to render care to those individuals. We will build the case that if steps are taken to reduce risks-optimal personal protective equipment and training-to what is essentially the lowest possible level then rendering care should be seen as obligatory. If not, as in the AIDS era there will be an unfair distribution of risk, with those who take their obligations seriously having to go beyond their fair measure of exposure. It would also potentially undermine patients' faith in the altruism of physicians and thereby degrade the esteem in which our profession is held and the trust that underpins the therapeutic relationship. Finally there is an implicit contract with society. Society gives tremendously to us; we encumber a debt from all society does and offers, a debt for which recompense is rarely sought. The mosaic of moral, historical, and professional imperatives to render care to the infected all echoes the words of medicine's moral leaders in the AIDS epidemic. Arnold Relman perhaps put it most succinctly, "the risk of contracting the patient's disease is one of the risks that is inherent in the profession of medicine. Physicians who are not willing to accept that risk…ought not be in the practice of medicine." Copyright © 2015 Elsevier Inc. All rights reserved.

    The association between vitamin D and clinical parameters in obstructive lung diseases (OLDs), including COPD and bronchial asthma, was previously investigated. As asthma-COPD overlap syndrome (ACOS) is a new clinical entity, the prevalence of vitamin D levels in ACOS is unknown. Our aim was to assess the levels of circulating vitamin D (25-hydroxyvitamin D [25(OH)D]) in different OLDs, including ACOS patients, and its correlation with clinical parameters. A total of 106 men and women (control, n=21; asthma, n=44; COPD, n=21; and ACOS, n=20) were involved in the study. All patients underwent detailed clinical examinations; disease control and severity was assessed by disease-specific questionnaires (COPD assessment test, asthma control test, and modified Medical Research Council); furthermore, 25(OH)D levels were measured in all patients. The 25(OH)D level was significantly lower in ACOS and COPD groups compared to asthma group (16.86±1.79 ng/mL and 14.27±1.88 ng/mL vs 25.66±1.91 ng/mL). A positive correlation was found between 25(OH)D level and forced expiratory volume in 1 second (r=0.4433; PD level showed a positive correlation in the ACOS (r=0.4761; P=0.0339) but not in the asthma group. Higher COPD assessment test total scores correlated with decreased 25(OH)D in ACOS (r=-0.4446; P=0.0495); however, this was not observed in the COPD group. Vitamin D deficiency is present in ACOS patients and circulating 25(OH)D level may affect disease control and severity.

    Full Text Available Background: Cerebellar ataxia, mental retardation, and disequilibrium syndrome (CAMRQ is a heterogeneous group of genetic disorders that have been grouped by shared clinical features; all of these features are transmitted via an autosomal recessive mechanism. Four variants of this syndrome have been identified so far, and each one differs in terms of both clinical and genotypical features. CAMRQ4 is a rare genetic disorder characterized by mental retardation, ataxia or an inability to walk, dysarthria and, in some patients, quadrupedal gait. Methods: We investigated three Saudi families with CAMRQ4. Blood samples were collected from the affected patients, their parents, and healthy siblings. DNA was extracted from whole blood, and whole-exome sequencing was performed. Findings were confirmed by segregation analysis, which was performed on other family members. Results: Thus far, 17 patients have been affected by CAMRQ4. Genetic analysis of all patients, including our current patients, showed a mutation in the aminophospholipid transporter, class I, type 8A, member 2 gene ( ATP8A2 . A series of common phenotypical features have been reported in these patients, with few exceptions. Ataxia, mental retardation, and hypotonia were present in all patients, consanguinity in 90% and abnormal movements in 50%. Moreover, 40% achieved ambulation at least once in their lifetime, 40% had microcephaly, whereas 30% were mute. Magnetic resonance imaging (MRI of the brain was normal in 60% of patients. Conclusions: We described the largest cohort of patients with CAMRQ4 syndrome and identified three novel mutations. CAMRQ4 syndrome should be suspected in patients presenting with ataxia, intellectual disability, hypotonia, microcephaly, choreoathetoid movements, ophthalmoplegia, and global developmental delay, even if brain MRI appears normal.

    Adaptor protein complex-4 (AP-4) is a heterotetrameric protein complex which plays a key role in vesicle trafficking in neurons. Mutations in genes affecting different subunits of AP-4, including AP4B1, AP4E1, AP4S1, and AP4M1, have been recently associated with an autosomal recessive phenotype, consisting of spastic tetraplegia, and intellectual disability (ID). The overlapping clinical picture among individuals carrying mutations in any of these genes has prompted the terms "AP-4 deficiency syndrome" for this clinically recognizable phenotype. Using whole-exome sequencing, we identified a novel homozygous mutation (c.991C>T, p.Q331*, NM_006594.4) in AP4B1 in two siblings from a consanguineous Pakistani couple, who presented with severe ID, progressive spastic tetraplegia, epilepsy, and microcephaly. Sanger sequencing confirmed the mutation was homozygous in the siblings and heterozygous in the parents. Similar to previously reported individuals with AP4B1 mutations, brain MRI revealed ventriculomegaly and white matter loss. Interestingly, in addition to the typical facial gestalt reported in other AP-4 deficiency cases, the older brother presented with congenital left Horner syndrome, bilateral optic nerve atrophy and cataract, which have not been previously reported in this condition. In summary, we report a novel AP4B1 homozygous mutation in two siblings and review the phenotype of AP-4 deficiency, speculating on a possible role of AP-4 complex in eye development. © 2018 Wiley Periodicals, Inc.

    Growth impairment in short stature homeobox-containing gene (SHOX) deficiency and Turner syndrome share a similar etiology. Because of the established effect of GH treatment on height in patients with Turner syndrome, we hypothesized that GH therapy would also stimulate growth in patients with SHOX deficiency. Our objectives were to evaluate long-term efficacy of GH treatment in short patients with SHOX deficiency and to compare the effect on final (adult) height (FH) in patients with SHOX deficiency and Turner syndrome. A prospective, multinational, open-label, randomized 3-arm study consisting of a 2-year control period and a subsequent extension period to FH. The treatment groups were 1) SHOX-D-C/GH (untreated during the control period, GH-treated during the extension), 2) SHOX-D-GH/GH, and 3) Turner-GH/GH (GH-treated during both study periods). Short-statured prepubertal patients with genetically confirmed SHOX deficiency (n = 49) or Turner syndrome (n = 24) who participated in the extension. Depending on the study arm, patients received a daily sc injection of 0.05 mg/kg recombinant human GH from start of the study or start of the extension until attainment of FH or study closure. Height SD score gain from start of GH treatment to FH was similar between the combined SHOX-deficient groups (n = 28, 1.34 ± 0.18 [least-squares mean ± SE]) and the Turner group (n = 19, 1.32 ± 0.22). In this FH population, 57% of the patients with SHOX deficiency and 32% of the patients with Turner syndrome achieved a FH greater than -2 SD score. GH treatment in short children with SHOX deficiency showed similar long-term efficacy as seen in girls with Turner syndrome.

    Heterozygous mutations in one of the mismatch repair (MMR) genes MLH1, MSH2, MSH6 and PMS2 cause the dominant adult cancer syndrome termed Lynch syndrome or hereditary non-polyposis colorectal cancer. During the past 10 years, some 35 reports have delineated the phenotype of patients with biallelic inheritance of mutations in one of these MMR genes. The patients suffer from a condition that is characterised by the development of childhood cancers, mainly haematological malignancies and/or brain tumours, as well as early-onset colorectal cancers. Almost all patients also show signs reminiscent of neurofibromatosis type 1, mainly café au lait spots. Alluding to the underlying mechanism, this condition may be termed as "constitutional mismatch repair-deficiency (CMMR-D) syndrome". To give an overview of the current knowledge and its implications of this recessively inherited cancer syndrome we summarise here the genetic, clinical and pathological findings of the so far 78 reported patients of 46 families suffering from this syndrome.

    Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown aetiology. We report a 27-year-old male patient with diabetes, who presented with a nonhealing ulcer on the left leg, pruritic hyperpigmented papules distributed over the trunk and limbs, and chronic diarrhoea. He had eosinophilia, low haemoglobin and serum IgE levels, and raised erythrocyte sedimentation rate. Histopathology of the leg ulcer was consistent with the diagnosis of PG, while the histology of the hyperpigmented papule revealed tissue eosinophilia. Subsequent evaluation was conclusive of the diagnosis of PG, idiopathic hypereosinophilic syndrome (IHES) and selective IgE deficiency. Dexamethasone pulse therapy achieved resolution of the ulcer and reduction in the eosinophilia. Further evaluation for the persistent diarrhoea led to a diagnosis of lymphocytic colitis (LC), which responded to budesonide. To our knowledge, the association of PG with IHES, selective IgE deficiency or LC has not been previously reported. © 2015 British Association of Dermatologists.

    Nitric oxide (NO) is synthesised not only from L-arginine by NO synthases (NOSs), but also from its inert metabolites, nitrite and nitrate. Green leafy vegetables are abundant in nitrate, but whether or not a deficiency in dietary nitrite/nitrate spontaneously causes disease remains to be clarified. In this study, we tested our hypothesis that long-term dietary nitrite/nitrate deficiency would induce the metabolic syndrome in mice. To this end, we prepared a low-nitrite/nitrate diet (LND) consisting of an amino acid-based low-nitrite/nitrate chow, in which the contents of L-arginine, fat, carbohydrates, protein and energy were identical with a regular chow, and potable ultrapure water. Nitrite and nitrate were undetectable in both the chow and the water. Three months of the LND did not affect food or water intake in wild-type C57BL/6J mice compared with a regular diet (RD). However, in comparison with the RD, 3 months of the LND significantly elicited visceral adiposity, dyslipidaemia and glucose intolerance. Eighteen months of the LND significantly provoked increased body weight, hypertension, insulin resistance and impaired endothelium-dependent relaxations to acetylcholine, while 22 months of the LND significantly led to death mainly due to cardiovascular disease, including acute myocardial infarction. These abnormalities were reversed by simultaneous treatment with sodium nitrate, and were significantly associated with endothelial NOS downregulation, adiponectin insufficiency and dysbiosis of the gut microbiota. These results provide the first evidence that long-term dietary nitrite/nitrate deficiency gives rise to the metabolic syndrome, endothelial dysfunction and cardiovascular death in mice, indicating a novel pathogenetic role of the exogenous NO production system in the metabolic syndrome and its vascular complications.

    Constitutional mismatch repair deficiency (CMMRD) is a cancer predisposition syndrome associated with a high risk of developing early-onset malignancies of the blood, brain, and intestinal tract. We present the case of a patient with T-lymphoblastic lymphoma at the age of 3 years, followed by Burkitt lymphoma 10 years later. This patient also exhibited numerous nonmalignant findings including café au lait spots, lipomas, bilateral renal nodules, a nonossifying fibroma, multiple colonic adenomas, and a rapidly enlarging pilomatrixoma. The spectrum of malignant and nonmalignant neoplasms in this patient highlights the remarkable diversity, and early onset, of lesions seen in children with CMMRD. © 2016 Wiley Periodicals, Inc.

    Laron syndrome (LS) or primary GH insensitivity is a unique human model to study the effects of congenital IGF-I deficiency. Within our cohort of 63 patients with LS, 15 female patients were regularly followed since birth or infancy, throughout puberty. We observed that they were short at birth, with small genitalia and gonads -- during puberty, developed delayed puberty but eventually reached between 16 and 19 1/2 years full sexual development. Reproduction is unaffected at a young adult age. It is concluded that IGF-I in concert with the sex hormones has a modulatory but not essential function on female sexual development and maturation.

    The Acquired Immuno-deficiency Syndrome (AIDS) was first recognized in the spring of 1981 in New York and California by the centers for Disease Control (CDC). Subsequently there have been numerous invasive and non-invasive methods proposed for the early diagnosis and treatment of this usually fatal disorder. This article reviews the ongoing role of nuclear medicine in the diagnosis of HIV infection and HIV related diseases over the last decade as well as some recently introduced radionuclide investigations that are still in the realm of 'work in progress'.

As asthma–COPD overlap syndrome (ACOS is a new clinical entity, the prevalence of vitamin D levels in ACOS is unknown.Aim: Our aim was to assess the levels of circulating vitamin D (25-hydroxyvitamin D [25(OHD] in different OLDs, including ACOS patients, and its correlation with clinical parameters.Methods: A total of 106 men and women (control, n=21; asthma, n=44; COPD, n=21; and ACOS, n=20 were involved in the study. All patients underwent detailed clinical examinations; disease control and severity was assessed by disease-specific questionnaires (COPD assessment test, asthma control test, and modified Medical Research Council; furthermore, 25(OHD levels were measured in all patients.Results: The 25(OHD level was significantly lower in ACOS and COPD groups compared to asthma group (16.86±1.79 ng/mL and 14.27±1.88 ng/mL vs 25.66±1.91 ng/mL. A positive correlation was found between 25(OHD level and forced expiratory volume in 1 second (r=0.4433; P<0.0001, forced vital capacity (FVC (r=0.3741; P=0.0004, forced expiratory flow between 25% and 75% of FVC (r=0.4179; P<0.0001, and peak expiratory flow (r=0.4846; P<0.0001 in OLD patient groups. Asthma control test total scores and the 25(OHD level showed a positive correlation in the ACOS (r=0.4761; P=0.0339 but not in the asthma group. Higher COPD assessment test total scores correlated with decreased 25(OHD in ACOS (r=-0.4446; P=0.0495; however, this was not observed in the COPD group.Conclusion: Vitamin D deficiency is present in ACOS patients and

    To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the polycystic ovary syndrome, another with the same age, educational status and presence or absence of sexual partners was sought without this diagnosis. In total, 166 patients agreed to participate, consisting of 95 diagnosed with polycystic ovary syndrome and 71 in the Control Group. The diagnosis of polycystic ovary syndrome was made by the presence of two from three criteria: oligomenorrhea or amenorrhea, clinical or biochemical hyperandrogenism and polycystic ovaries on transvaginal ultrasound, following exclusion of patients with Cushing's syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors. Weight and height were measured to calculate the body mass index. The Self-Reporting Questionnaire, which evaluated 20 items, was used as an indicator of common mental disorders. A χ² analysis stratified by the category of body mass index was used to compare the prevalence of common mental disorders, between the groups of women with and without the polycystic ovary syndrome. There were no significant differences in age, education, presence of sexual partners, ethnicity, socioeconomic status, use of psychiatric medication, and search for consultation in mental health between the studied groups. The prevalence of obese women with indications of common mental disorders was significantly higher in women with polycystic ovary syndrome than in the Control Group. In the group with healthy body mass index, the incidence of common mental disorders was statistically significant different between women with polycystic ovary syndrome and normal controls (p=0.008).

    Systems biology and bioinformatics provide the feasibility for the basic research associated with "same traditional Chinese medicine (TCM) syndrome in different diseases". In this study, the plasma proteins in postoperative colorectal (PCC) and postoperative liver cancer (PLC) patients with YDLKS (Yin deficiency of liver-kidney syndrome) were screened out using iTRAQ combined with LC-MS/MS technology. The results demonstrated that, KNG1, AMBP, SERPING1, etc, were all differentially expressed in both PCC and PLC patients with YDLKS, and associated closely with complement and coagulation cascades pathway. C7 and C2 were another two representative factors involving in former pathway. Further validation showed that, the C7 levels were increased significantly in PLC ( P patients with YDLKS ( P patients with YDLKS ( P patients with YDLKS.

    We report that a 4-year-old boy presented with right unilateral complete cleft lip and palate, right anophthalmos, left congenital nystagmus, absence of the vomer bone, mental-motor retardation, and normal lymphocyte karyotype (46, XY). For reconstruction of the deformities, we performed cleft lip repair by Millard's rotation-advancement technique and planned cleft palate repair. This combination of cleft lip and palate, anophthalmos, congenital nystagmus, absent vomer bone, and mental-motor retardation has not, to our knowledge, previously been described. We suggest that this represents either another case of the rare Fryns "anophthalmia-plus" syndrome or a new syndrome.

    In this report we present two brothers with abnormal neurological development, hypotonia, short stature, pylorus stenosis, pectus excavatum, brachycephaly due to craniosynostosis, frontal bossing, depressed nasal bridge, high arched-wide palate, downslant palpebral fissures, low-set, large ears, thin upper lip and bilateral cryptorchidism. The brothers were born to a couple of second cousins and were the third and fourth pregnancies of the mother. The father, the mother and the eldest sibling were phenotypically and chromosomally normal. The clinical findings of the brothers were found to be similar. These clinical findings were compared with syndromes showing some of the symptoms, namely Apert, FG, Floating-Harbor, Shprintzen-Goldberg and Rett Syndromes. However, when the findings were detailed, we observed that they did not match completely any of the syndromes in a discernable way. The MECP2 gene mutation was analysed because of mental retardation, poor neurological evolution and large ears, but no mutation was found. So these cases are presented as a new syndrome with apparent autosomal recessive inheritance.

    The aim of this study was to identify the effects of vitamin D supplementation on insulin sensitivity and androgen levels in vitamin-D-deficient polycystic ovary syndrome (PCOS) patients. Sixty-seven vitamin-D-deficient (25-hydroxyvitamin D [25(OH)D] levels below 20 ng/mL) PCOS patients and 54 vitamin-D-deficient non-PCOS volunteer subjects matched for age and body mass index were enrolled to this prospective study. All participants were given 50 000 IU/week cholecalciferol orally for 8 weeks and 1500 IU/day for 4 weeks. Insulin sensitivity was calculated with the Matsuda insulin sensitivity index (ISI) based on an oral glucose tolerance test. Matsuda ISI, gonadal hormones (estrogen, testosterone, androstenedione), and 25(OH)D levels were studied before and at the end of the 12th week of vitamin D load. After vitamin D supplementation, serum androstenedione levels had decreased significantly (P = 0.007) and Matsuda ISI values had increased significantly (P = 0.001) in the PCOS group but no significant changes were seen in those parameters in controls. We observed positive correlations between 25(OH)D levels and Matsuda ISI (r = 0.307; P < 0.01), and negative correlations between 25(OH)D levels and total testosterone (r = -0.306; P < 0.01) and androstenedione (r = -0.275; P < 0.01) levels in the PCOS group. Vitamin D supplementation increased insulin sensitivity and decreased androgen levels in vitamin-D-deficient women with PCOS but did not have any effect in vitamin-D-deficient non-PCOS women. These results may indicate the possible role of vitamin D in the complex pathogenesis of PCOS. © 2017 Japan Society of Obstetrics and Gynecology.

    To examine the relationship between inflammation and the comorbidity of mental disorders with irritable bowel syndrome (IBS) by comparing intestinal mucosa inflammatory biomarkers in patients with and without mental disorders. A total of 43 consecutive IBS patients fulfilling the Rome III criteria and 15 volunteers serving as controls without digestive symptoms were recruited and interviewed with Composite International Diagnostic Interview (CIDI) by the well-trained staff and thus classified as with or without mental disorders. All subjects underwent colonoscopy and biopsies were acquired from the mucosa of distal ileum and colon. CD3(+) lymphocytes, mast cells, 5-HT positive cells and (indoleamine 2,3-dioxygenase) IDO positive cells were identified immunohistologically in mucosa biopsies in volunteers (n = 13), IBS patients without mental disorder (n = 24) and IBS patients with mental disorder (n = 19). The incidence of mental disorders in IBS patients was significantly higher than that in the volunteers (19/43 vs 2/15, P = 0.012), including 9 patients with anxiety disorders and 8 with mood disorders. (1) The number of mast cells in IBS patients with mental disorder and that in IBS patients without mental disorder has no statistical significance ((16.7 ± 3.6)/HP vs (15.4 ± 3.1)/HP in distal ileum, (12.8 ± 2.2)/HP vs (12.3 ± 2.5)/HP in sigmoid, both P > 0.05). Similar results were seen in 5-HT positive cells ((3.7 ± 0.9)/HP vs (3.4 ± 0.8)/HP in distal ileum, (6.1 ± 1.8)/HP vs (5.2 ± 1.8)/HP in sigmoid, both P > 0.05). In distal ileum, the number of CD3(+) cells in IBS patients with mental disorder has no statistical significance with that in the IBS patients without mental disorder ((62 ± 16)/HP vs (55 ± 22)/HP, P > 0.05). Similar results were seen in IDO positive cells (6(2, 8)/HP vs 2(1, 5)/HP, P > 0.05).

    Untreated patients with congenital growth hormone deficiency (GHD) and IGF-I deficiency are characterized not only by dwarfism but also by acromicria and organomicria, such as the heart. We assessed cardiac dimensions and function in very young patients with Laron syndrome (LS) undergoing IGF-I replacement therapy. Two to seven echocardiographic measurements were performed during IGF-I replacement therapy on male (n=4) and female (n=4) LS -patients, mean+/-SD age of 7.1+/-3.6 years (range 1.6-11.6 years), weight 16.1+/-9.7 kg, and height 89.9+/-18.5 cm. As aged- and gender-matched controls served 44 healthy children, age: 8.7+/-5.5 years, weight: 36.1+/-22.4 kg, and height: 129.7+/-33.1cm. Data of LS patients were normalized to body surface area and compared to the control group as well as nomograms of normal echocardiographic parameters for this age group. Left ventricular diastolic and systolic dimensions (LVDD/ LVSD, mm) and LV mass (gr) were significantly smaller in boys and girls with IGF-I treated LS compared with controls while the shortening fraction (%) and intraventricular septum thickness (mm) were similar. When compared with standard values for this age group, all treated LS patients were within 1 standard deviation of the mean. IGF-I therapy of young patients with Laron syndrome maintain LV dimensions and function within the normal range of aged-matched controls.

    2015-10-01

    Tourette syndrome (TS) can feature complex tics involving socially inappropriate behaviours. Adults with TS can also demonstrate differences to healthy controls when reasoning about mental states. This study investigated spontaneous mentalizing in TS. Twenty adults with TS and twenty healthy controls completed the animations task. Participants were asked to watch short ambiguous animations involving two triangles and describe what was happening. Some animations featured random movement of the triangles, while others depicted social interactions that were simple (e.g., dancing) or more complex (e.g., one triangle tricking the other). Measures were taken of executive functions, alexithymia and clinical symptoms. Individuals with TS responded similarly to controls when viewing animations featuring simple and complex interactions, demonstrating intact mentalizing ability. However, significant group differences were apparent for the random movement animations. TS was associated with a greater tendency to attribute mental states during this condition, and to describe random movements as motivated actions guided by the intentions of the triangles. There were no group differences for the alexithymia scale, but TS was associated with mild executive deficits. No relationships were apparent between animation responses and other measures. Our findings suggest that TS is associated with a propensity to adopt the intentional stance. Hyper-mentalizing in TS could be linked to both dopamine dysfunction and altered social behaviour, whereby amplified salience of social cues could contribute to the complex interplay between environmental context and tic expression. These observations may offer further insight into the potential effects of dopamine dysfunction on social cognition. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Here we report a patient with 11p15.4p15.5 duplication and 13q34 deletion presenting with Beckwith-Wiedemann syndrome (BWS) and moderate deficiency of factor VII (FVII). The duplication was initially diagnosed on methylation-sensitive multiplex ligation-dependent probe amplification. Array comparative genome hybridization confirmed its presence and indicated a 13q34 distal deletion. The patient's clinical symptoms, including developmental delay and facial dysmorphism, were typical of BWS with paternal 11p15 trisomy. Partial 13q monosomy in this patient is associated with moderate deficiency of FVII and may also overlap with a few symptoms of paternal 11p15 trisomy such as developmental delay and some facial features. To our knowledge this is the first report of 11p15.4p15.5 duplication associated with deletion of 13q34 and FVII deficiency. Moreover, this report emphasizes the importance of detailed clinical as well as molecular examinations in patients with BWS features and developmental delay. © 2015 Japan Pediatric Society.

    The tenascin-X (TNX) deficient type Ehlers-Danlos syndrome (EDS) is similar to the classical type of EDS. Because of the limited awareness among geneticists and the challenge of the molecular analysis of the TNXB gene, the TNX-deficient type EDS is probably to be under diagnosed. We therefore performed an observational, cross-sectional study. History and physical examination were performed. Results of serum TNX measurements were collected and mutation analysis was performed by a combination of next-generation sequencing (NGS), Sanger sequencing and multiplex ligation-dependent probe amplification (MLPA). Included were 17 patients of 11 families with autosomal recessive inheritance and childhood onset. All patients had hyperextensible skin without atrophic scarring. Hypermobility of the joints was observed in 16 of 17 patients. Deformities of the hands and feet were observed frequently. TNX serum level was tested and absent in 11 patients (seven families). Genetic testing was performed in all families; 12 different mutations were detected, most of which are suspected to lead to non-sense mRNA mediated decay. In short, patients with the TNX-deficient type EDS typically have generalized joint hypermobility, skin hyperextensibility and easy bruising. In contrast to the classical type, the inheritance pattern is autosomal recessive and atrophic scarring is absent. Molecular analysis of TNXB in a diagnostic setting is challenging. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Jacobsen syndrome (JBS) is a rare congenital disorder caused by a terminal deletion of the long arm of chromosome 11. A subset of patients exhibit social behavioural problems that meet the diagnostic criteria for autism spectrum disorder (ASD); however, the underlying molecular pathogenesis remains poorly understood. PX-RICS is located in the chromosomal region commonly deleted in JBS patients with autistic-like behaviour. Here we report that PX-RICS-deficient mice exhibit ASD-like social behaviours and ASD-related comorbidities. PX-RICS-deficient neurons show reduced surface γ-aminobutyric acid type A receptor (GABAAR) levels and impaired GABAAR-mediated synaptic transmission. PX-RICS, GABARAP and 14-3-3ζ/θ form an adaptor complex that interconnects GABAAR and dynein/dynactin, thereby facilitating GABAAR surface expression. ASD-like behavioural abnormalities in PX-RICS-deficient mice are ameliorated by enhancing inhibitory synaptic transmission with a GABAAR agonist. Our findings demonstrate a critical role of PX-RICS in cognition and suggest a causal link between PX-RICS deletion and ASD-like behaviour in JBS patients.

    Patients with bi-allelic germline mutations in mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2) develop a rare but severe variant of Lynch syndrome called constitutional MMR deficiency (CMMRD). This syndrome is characterized by early-onset colorectal cancers, lymphomas or leukemias, and brain tumors. There is no satisfactory method for diagnosis of CMMRD because screens for mutations in MMR genes are noninformative for 30% of patients. MMR-deficient cancer cells are resistant to genotoxic agents and have microsatellite instability (MSI), due to accumulation of errors in repetitive DNA sequences. We investigated whether these features could be used to identify patients with CMMRD. We examined MSI by PCR analysis and tolerance to methylating or thiopurine agents (functional characteristics of MMR-deficient tumor cells) in lymphoblastoid cells (LCs) from 3 patients with CMMRD and 5 individuals with MMR-proficient LCs (controls). Using these assays, we defined experimental parameters that allowed discrimination of a series of 14 patients with CMMRD from 52 controls (training set). We then used the same parameters to assess 23 patients with clinical but not genetic features of CMMRD. In the training set, we identified parameters, based on MSI and LC tolerance to methylation, that detected patients with CMMRD vs controls with 100% sensitivity and 100% specificity. Among 23 patients suspected of having CMMRD, 6 had MSI and LC tolerance to methylation (CMMRD highly probable), 15 had neither MSI nor LC tolerance to methylation (unlikely to have CMMRD), and 2 were considered doubtful for CMMRD based on having only 1 of the 2 features. The presence of MSI and tolerance to methylation in LCs identified patients with CMMRD with 100% sensitivity and specificity. These features could be used in diagnosis of patients.

  7. Deficiency in origin licensing proteins impairs cilia formation: implications for the aetiology of Meier-Gorlin syndrome.

    Directory of Open Access Journals (Sweden)

    Tom Stiff

    Full Text Available Mutations in ORC1, ORC4, ORC6, CDT1, and CDC6, which encode proteins required for DNA replication origin licensing, cause Meier-Gorlin syndrome (MGS, a disorder conferring microcephaly, primordial dwarfism, underdeveloped ears, and skeletal abnormalities. Mutations in ATR, which also functions during replication, can cause Seckel syndrome, a clinically related disorder. These findings suggest that impaired DNA replication could underlie the developmental defects characteristic of these disorders. Here, we show that although origin licensing capacity is impaired in all patient cells with mutations in origin licensing component proteins, this does not correlate with the rate of progression through S phase. Thus, the replicative capacity in MGS patient cells does not correlate with clinical manifestation. However, ORC1-deficient cells from MGS patients and siRNA-mediated depletion of origin licensing proteins also have impaired centrosome and centriole copy number. As a novel and unexpected finding, we show that they also display a striking defect in the rate of formation of primary cilia. We demonstrate that this impacts sonic hedgehog signalling in ORC1-deficient primary fibroblasts. Additionally, reduced growth factor-dependent signaling via primary cilia affects the kinetics of cell cycle progression following cell cycle exit and re-entry, highlighting an unexpected mechanism whereby origin licensing components can influence cell cycle progression. Finally, using a cell-based model, we show that defects in cilia function impair chondroinduction. Our findings raise the possibility that a reduced efficiency in forming cilia could contribute to the clinical features of MGS, particularly the bone development abnormalities, and could provide a new dimension for considering developmental impacts of licensing deficiency.

    2014-02-01

    In light of the high number of people discontinuing antipsychotics each year, it is essential that nurses develop a robust understanding of all aspects of the discontinuation experience. While there is a large body of published work documenting post-discontinuation relapse rates, less is known about other aspects of the discontinuation experience. This paper presents the results of a narrative review of international studies of antipsychotic discontinuation syndromes and their relevance to nursing practice. Four key mental health nursing textbooks used in student nurse education in Australia are examined to assess how this evidence has been incorporated into clinical recommendations. This review finds that the evidence for discontinuation syndromes could be more widely disseminated and applied than it is at present. Strikingly, this evidence has not been incorporated into key mental health nursing textbooks in Australia at all. Slow integration into nursing published work may be influenced by a number of clinical and research uncertainties. We consider the impact of this silence on key nursing roles of psycho-education and adverse event monitoring during antipsychotic discontinuation periods. Further robust research should be conducted into discontinuation syndromes as a matter of urgency. Given the high number of consumers potentially impacted upon by discontinuation syndromes, nurse authors and educators should consider revising key nursing textbooks to include the currently available information about discontinuation syndromes. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

    affected by an individual's D2 density in the VTA mediated interaction of the NAc. It is therefore hypothesized that carriers of DRD2 A1 allele may respond significantly differently to carriers of the DRD2 A2 genotype. In this regard, carriers of the D2 A1 allele have a blunted response to glucose and monetary rewards. In contrast powerful D2 agonists like bromocryptine show a heightened activation of the reward circuitry only in DRD2 A1 allele carriers. If music causes a powerful activation in spite of the DRD2 A1 allele due to a strong DA neuronal release which subsequently impinges on existing D2 receptors, then it is reasonable to assume that music is a strong indirect D2 agonist (by virtue of DA neuronal release in the NAc) and may have important therapeutic applicability in Reward Deficiency Syndrome (RDS) related behaviors including Substance Use Disorder (SUD). Ross et al. [18] found that music therapy appears to be a novel motivational tool in a severely impaired inpatient sample of patients with co-occurring mental illness and addiction.

  11. Unique DNA repair gene variations and potential associations with the primary antibody deficiency syndromes IgAD and CVID.

    Directory of Open Access Journals (Sweden)

    Steven M Offer

    Full Text Available BACKGROUND: Despite considerable effort, the genetic factors responsible for >90% of the antibody deficiency syndromes IgAD and CVID remain elusive. To produce a functionally diverse antibody repertoire B lymphocytes undergo class switch recombination. This process is initiated by AID-catalyzed deamination of cytidine to uridine in switch region DNA. Subsequently, these residues are recognized by the uracil excision enzyme UNG2 or the mismatch repair proteins MutSalpha (MSH2/MSH6 and MutLalpha (PMS2/MLH1. Further processing by ubiquitous DNA repair factors is thought to introduce DNA breaks, ultimately leading to class switch recombination and expression of a different antibody isotype. METHODOLOGY/PRINCIPAL FINDINGS: Defects in AID and UNG2 have been shown to result in the primary immunodeficiency hyper-IgM syndrome, leading us to hypothesize that additional, potentially more subtle, DNA repair gene variations may underlie the clinically related antibody deficiencies syndromes IgAD and CVID. In a survey of twenty-seven candidate DNA metabolism genes, markers in MSH2, RAD50, and RAD52 were associated with IgAD/CVID, prompting further investigation into these pathways. Resequencing identified four rare, non-synonymous alleles associated with IgAD/CVID, two in MLH1, one in RAD50, and one in NBS1. One IgAD patient carried heterozygous non-synonymous mutations in MLH1, MSH2, and NBS1. Functional studies revealed that one of the identified mutations, a premature RAD50 stop codon (Q372X, confers increased sensitivity to ionizing radiation. CONCLUSIONS: Our results are consistent with a class switch recombination model in which AID-catalyzed uridines are processed by multiple DNA repair pathways. Genetic defects in these DNA repair pathways may contribute to IgAD and CVID.

    Background Zinc deficiency‐like (ZDL) syndrome is an inherited defect of Fleckvieh calves, with striking similarity to bovine hereditary zinc deficiency (BHZD). However, the causative mutation in a phospholipase D4 encoding gene (PLD4) shows no connection to zinc metabolism. Objectives To describe clinical signs, laboratory variables, and pathological findings of ZDL syndrome and their utility to differentiate ZDL from BHZD and infectious diseases with similar phenotype. Animals Nine hospitalized calves with crusting dermatitis and confirmed mutation in PLD4 and medical records from 25 calves with crusting dermatitis or suspected zinc deficiency. Methods Prospective and retrospective case series. Results The 9 calves (age: 5–53 weeks) displayed a moderate to severe crusting dermatitis mainly on the head, ventrum, and joints. Respiratory and digestive tract inflammations were frequently observed. Zinc supplementation did not lead to remission of clinical signs in 4 calves. Laboratory variables revealed slight anemia in 8 calves, hypoalbuminemia in 6 calves, but reduced serum zinc concentrations in only 3 calves. Mucosal erosions/ulcerations were present in 7 calves and thymus atrophy or reduced thymic weights in 8 calves. Histologically, skin lesions were indistinguishable from BHZD. Retrospective analysis of medical records revealed the presence of this phenotype since 1988 and pedigree analysis revealed a common ancestor of several affected calves. Conclusions and Clinical Importance ZDL syndrome should be suspected in Fleckvieh calves with crusting dermatitis together with diarrhea or respiratory tract inflammations without response to oral zinc supplementation. Definite diagnosis requires molecular genetic confirmation of the PLD4 mutation. PMID:29424482

  13. Clinical Endocannabinoid Deficiency Reconsidered: Current Research Supports the Theory in Migraine, Fibromyalgia, Irritable Bowel, and Other Treatment-Resistant Syndromes.

    2016-01-01

    Medicine continues to struggle in its approaches to numerous common subjective pain syndromes that lack objective signs and remain treatment resistant. Foremost among these are migraine, fibromyalgia, and irritable bowel syndrome, disorders that may overlap in their affected populations and whose sufferers have all endured the stigma of a psychosomatic label, as well as the failure of endless pharmacotherapeutic interventions with substandard benefit. The commonality in symptomatology in these conditions displaying hyperalgesia and central sensitization with possible common underlying pathophysiology suggests that a clinical endocannabinoid deficiency might characterize their origin. Its base hypothesis is that all humans have an underlying endocannabinoid tone that is a reflection of levels of the endocannabinoids, anandamide (arachidonylethanolamide), and 2-arachidonoylglycerol, their production, metabolism, and the relative abundance and state of cannabinoid receptors. Its theory is that in certain conditions, whether congenital or acquired, endocannabinoid tone becomes deficient and productive of pathophysiological syndromes. When first proposed in 2001 and subsequently, this theory was based on genetic overlap and comorbidity, patterns of symptomatology that could be mediated by the endocannabinoid system (ECS), and the fact that exogenous cannabinoid treatment frequently provided symptomatic benefit. However, objective proof and formal clinical trial data were lacking. Currently, however, statistically significant differences in cerebrospinal fluid anandamide levels have been documented in migraineurs, and advanced imaging studies have demonstrated ECS hypofunction in post-traumatic stress disorder. Additional studies have provided a firmer foundation for the theory, while clinical data have also produced evidence for decreased pain, improved sleep, and other benefits to cannabinoid treatment and adjunctive lifestyle approaches affecting the ECS.

    Monoallelic PMS2 germline mutations cause 5%-15% of Lynch syndrome, a midlife cancer predisposition, whereas biallelic PMS2 mutations cause approximately 60% of constitutional mismatch repair deficiency (CMMRD), a rare childhood cancer syndrome. Recently improved DNA- and RNA-based strategies are applied to overcome problematic PMS2 mutation analysis due to the presence of pseudogenes and frequent gene conversion events. Here, we determined PMS2 mutation detection yield and mutation spectrum in a nationwide cohort of 396 probands. Furthermore, we studied concordance between tumor IHC/MSI (immunohistochemistry/microsatellite instability) profile and mutation carrier state. Overall, we found 52 different pathogenic PMS2 variants explaining 121 Lynch syndrome and nine CMMRD patients. In vitro mismatch repair assays suggested pathogenicity for three missense variants. Ninety-one PMS2 mutation carriers (70%) showed isolated loss of PMS2 in their tumors, for 31 (24%) no or inconclusive IHC was available, and eight carriers (6%) showed discordant IHC (presence of PMS2 or loss of both MLH1 and PMS2). Ten cases with isolated PMS2 loss (10%; 10/97) harbored MLH1 mutations. We confirmed that recently improved mutation analysis provides a high yield of PMS2 mutations in patients with isolated loss of PMS2 expression. Application of universal tumor prescreening methods will however miss some PMS2 germline mutation carriers. © 2016 WILEY PERIODICALS, INC.

    ATR-X (alpha-thalassemia/mental retardation, X-linked) syndrome is a human congenital disorder that causes severe intellectual disabilities. Mutations in the ATRX gene, which encodes an ATP-dependent chromatin-remodeler, are responsible for the syndrome. Approximately 50% of the missense mutations in affected persons are clustered in a cysteine-rich domain termed ADD (ATRX-DNMT3-DNMT3L, ADD{sub ATRX}), whose function has remained elusive. Here we identify ADD{sub ATRX} as a previously unknown histone H3-binding module, whose binding is promoted by lysine 9 trimethylation (H3K9me3) but inhibited by lysine 4 trimethylation (H3K4me3). The cocrystal structure of ADD{sub ATRX} bound to H3{sub 1-15}K9me3 peptide reveals an atypical composite H3K9me3-binding pocket, which is distinct from the conventional trimethyllysine-binding aromatic cage. Notably, H3K9me3-pocket mutants and ATR-X syndrome mutants are defective in both H3K9me3 binding and localization at pericentromeric heterochromatin; thus, we have discovered a unique histone-recognition mechanism underlying the ATR-X etiology.

    Constitutional mismatch repair deficiency (CMMR-D) syndrome is a rare inherited childhood cancer predisposition caused by biallelic germline mutations in one of the four mismatch repair (MMR)-genes, MLH1, MSH2, MSH6 or PMS2. Owing to a wide tumor spectrum, the lack of specific clinical features and the overlap with other cancer predisposing syndromes, diagnosis of CMMR-D is often delayed in pediatric cancer patients. Here, we report of three new CMMR-D patients all of whom developed more than one malignancy. The common finding in these three patients is agenesis of the corpus callosum (ACC). Gray matter heterotopia is present in two patients. One of the 57 previously reported CMMR-D patients with brain tumors (therefore all likely had cerebral imaging) also had ACC. With the present report the prevalence of cerebral malformations is at least 4/60 (6.6%). This number is well above the population birth prevalence of 0.09-0.36 live births with these cerebral malformations, suggesting that ACC and heterotopia are features of CMMR-D. Therefore, the presence of cerebral malformations in pediatric cancer patients should alert to the possible diagnosis of CMMR-D. ACC and gray matter heterotopia are the first congenital malformations described to occur at higher frequency in CMMR-D patients than in the general population. Further systematic evaluations of CMMR-D patients are needed to identify possible other malformations associated with this syndrome.

    Constitutional mismatch repair deficiency (CMMRD) syndrome is a distinct childhood cancer predisposition syndrome that results from biallelic germline mutations in one of the four MMR genes, MLH1, MSH2, MSH6 or PMS2. The tumour spectrum is very broad, including mainly haematological, brain and intestinal tract tumours. Patients show a variety of non-malignant features that are indicative of CMMRD. However, currently no criteria that should entail diagnostic evaluation of CMMRD exist. We present a three-point scoring system for the suspected diagnosis CMMRD in a paediatric/young adult cancer patient. Tumours highly specific for CMMRD syndrome are assigned three points, malignancies overrepresented in CMMRD two points and all other malignancies one point. According to their specificity for CMMRD and their frequency in the general population, additional features are weighted with 1-2 points. They include multiple hyperpigmented and hypopigmented skin areas, brain malformations, pilomatricomas, a second childhood malignancy, a Lynch syndrome (LS)-associated tumour in a relative and parental consanguinity. According to the scoring system, CMMRD should be suspected in any cancer patient who reaches a minimum of three points by adding the points of the malignancy and the additional features. The diagnostic steps to confirm or refute the suspected diagnosis are outlined. We expect that application of the suggested strategy for CMMRD diagnosis will increase the number of patients being identified at the time when they develop their first tumour. This will allow adjustment of the treatment modalities, offering surveillance strategies for second malignancies and appropriate counselling of the entire family.

    Full Text Available A 9-year-old Tajikistani girl presented to Keimyung University Dongsan Medical Center for evaluation of a skin lesion on her left eyelid, focal alopecia, unilateral ventricular dilatation, and aortic coarctation. She was diagnosed with encephalocraniocutaneous lipomatosis (ECCL according to Moog's diagnostic criteria. Café-au-lait spots were found on the left side of her trunk. Multiple nonossifying fibromas were found on her left proximal humerus, left distal femur, both proximal tibias, and left proximal fibula, suggesting Jaffe-Campanacci syndrome (JCS, following imaging of the extremities. Many JCS cases with multiple Café-au-lait macules, multiple nonossifying fibromas may actually have Neurofibromatosis type-1 (NF1. Thus, comprehensive molecular analysis to exclude NF1 mutation was performed using her blood sample. The NF1 mutation was not found. Her height was under the 3rd percentile and her bone age was delayed as compared with her chronological age. Baseline growth hormone (GH level was below the normal range. Using the insulin stimulation and levo-dihydroxyphenylalanine tests, GH deficiency was confirmed. We present a case of GH deficiency with typical features of ECCL and JCS.

    Molecular mechanisms underlying learning and memory remain imprecisely understood, and restorative interventions are lacking. We report that intranasal administration of siRNAs can be used to identify targets important in cognitive processes and to improve genetically impaired learning and memory. In mice modeling the intellectual deficiency of Fragile X syndrome, intranasally administered siRNA targeting glycogen synthase kinase-3β (GSK3β), histone deacetylase-1 (HDAC1), HDAC2, or HDAC3 diminished cognitive impairments. In WT mice, intranasally administered brain-derived neurotrophic factor (BDNF) siRNA or HDAC4 siRNA impaired learning and memory, which was partially due to reduced insulin-like growth factor-2 (IGF2) levels because the BDNF siRNA- or HDAC4 siRNA-induced cognitive impairments were ameliorated by intranasal IGF2 administration. In Fmr1 -/- mice, hippocampal IGF2 was deficient, and learning and memory impairments were ameliorated by IGF2 intranasal administration. Therefore intranasal siRNA administration is an effective means to identify mechanisms regulating cognition and to modulate therapeutic targets.

    Mismatch-repair deficient (MMR-D) malignancies include Lynch Syndrome (LS), which is secondary to germline mutations in one of the MMR genes, and the rare childhood-form of constitutional mismatch repair-deficiency (CMMR-D); caused by bi-allelic MMR gene mutations. A hallmark of LS-associated cancers is microsatellite instability (MSI), characterized by coding frameshift mutations (cFSM) in target genes. By contrast, tumors arising in CMMR-D patients are thought to display a somatic mutation pattern differing from LS. This study has the main goal to identify cFSM in MSI target genes relevant in CMMR-D and to compare the spectrum of common somatic mutations, including alterations in DNA polymerases POLE and D1 between LS and CMMR-D. CMMR-D-associated tumors harbored more somatic mutations compared to LS cases, especially in the TP53 gene and in POLE and POLD1, where novel mutations were additionally identified. Strikingly, MSI in classical mononucleotide markers BAT40 and CAT25 was frequent in CMMR-D cases. MSI-target gene analysis revealed mutations in CMMR-D-associated tumors, some of them known to be frequently hit in LS, such as RNaseT2, HT001, and TGFβR2. Our results imply a general role for these cFSM as potential new drivers of MMR-D tumorigenesis. © 2017 Wiley Periodicals, Inc.

    A 9-year-old Tajikistani girl presented to Keimyung University Dongsan Medical Center for evaluation of a skin lesion on her left eyelid, focal alopecia, unilateral ventricular dilatation, and aortic coarctation. She was diagnosed with encephalocraniocutaneous lipomatosis (ECCL) according to Moog's diagnostic criteria. Café-au-lait spots were found on the left side of her trunk. Multiple nonossifying fibromas were found on her left proximal humerus, left distal femur, both proximal tibias, and left proximal fibula, suggesting Jaffe-Campanacci syndrome (JCS), following imaging of the extremities. Many JCS cases with multiple Café-au-lait macules, multiple nonossifying fibromas may actually have Neurofibromatosis type-1 (NF1). Thus, comprehensive molecular analysis to exclude NF1 mutation was performed using her blood sample. The NF1 mutation was not found. Her height was under the 3rd percentile and her bone age was delayed as compared with her chronological age. Baseline growth hormone (GH) level was below the normal range. Using the insulin stimulation and levo-dihydroxyphenylalanine tests, GH deficiency was confirmed. We present a case of GH deficiency with typical features of ECCL and JCS.

    Full Text Available CONTEXT: Adhesion molecule deficiency type 1 is a rare disease that should be suspected in any patient whose umbilical cord presents delay in falling off, and who presents recurrent severe infections. Early diagnostic suspicion and early treatment improve the prognosis. CASE REPORT: The case of a four-month-old boy with recurrent hospitalizations because of severe bronchopneumonia and several episodes of acute otitis media with non-purulent drainage of mucus and positive bacterial cultures is presented. His medical history included neonatal sepsis and delayed umbilical cord detachment. Laboratory studies showed marked leukocytosis with predominance of neutrophils and decreased CD11b and CD18. These were all compatible with a diagnosis of leukocyte adhesion deficiency type I [LAD type 1].

    The objective of this study was to correlate the magnetic resonance (MR) images in patients with hormone deficiencies with the clinical data and the hormonal status. We studied 11 cases ef empty sella with different peripheral pituitary deficiencies. Hormone levels were determined according to standard laboratory methods. All the patients underwent MR imaging. The studies were carried out with a 1 Tesla superconducting magnet, using the cranial cavity for transmission and reception. Segittal and coronal T1-weighted spin-echo sequences (TR/TE: 600/15 ms), axial T2-weighted spin-echo sequences (TR/TE: 3,500/19/93 ms) and gadolinium-enhanced (=.2 cc/kg body weight) sagital and coronal T1-weighted spin-echo sequences (TR/TE: 600/15 ms) were employed. Six of the patients presented partial or total hypopituitarism associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH); there was one case of panhypopituitarism without SIADH and four cases of primary hypothyroidism, there of which were associated with pituitary deficiency, MR imaging revealed five cases of partially empty sella with residual pituitary gland on the sella floor and six cases in which the sella was completely empty. This study also identified six cases of normally situated neurohypophysis, another four in which the neurohypophysis could not be identified and one case of ectopic neurohypophysis. MR imaging is the technique of choice in the study of abnormal hypothalamic-pituitary activity. Empty and partially empty sella should be included among the frequent causes of hypopituitarism, although there is no clear relationship between the degree of adenohypophyseal insufficiency and the degree of atrophy of this system as viewed in MR images. In some cases, this entity may be the radiological sign of a phase in the development of an autoimmune inflammatory process involving the pituitary gland. (Author) 16 refs.

    Full Text Available Sjögren's syndrome (SS is a chronic, autoimmune exocrinopathy that leads to severe dryness of the mouth and eyes. Exocrine function is highly regulated by neuronal mechanisms but little is known about the link between chronic inflammation, innervation and altered exocrine function in the diseased eyes and exocrine glands of SS patients. To gain a better understanding of neuronal regulation in the immunopathogenesis of autoimmune exocrinopathy, we profiled a mouse model of spontaneous, autoimmune exocrinopathy that possess key characteristics of peripheral neuropathy experienced by SS patients. Mice deficient in the autoimmune regulator (Aire gene developed spontaneous, CD4+ T cell-mediated exocrinopathy and aqueous-deficient dry eye that were associated with loss of nerves innervating the cornea and lacrimal gland. Changes in innervation and tear secretion were accompanied by increased proliferation of corneal epithelial basal cells, limbal expansion of KRT19-positive progenitor cells, increased vascularization of the peripheral cornea and reduced nerve function in the lacrimal gland. In addition, we found extensive loss of MIST1+ secretory acinar cells in the Aire -/- lacrimal gland suggesting that acinar cells are a primary target of the disease, Finally, topical application of ophthalmic steroid effectively restored corneal innervation in Aire -/- mice thereby functionally linking nerve loss with local inflammation in the aqueous-deficient dry eye. These data provide important insight regarding the relationship between chronic inflammation and neuropathic changes in autoimmune-mediated dry eye. Peripheral neuropathies characteristic of SS appear to be tightly linked with the underlying immunopathological mechanism and Aire -/- mice provide an excellent tool to explore the interplay between SS-associated immunopathology and peripheral neuropathy.

    Abstract DNA mismatch repair (MMR) deficiency is one of the best understood forms of genetic instability in colorectal cancer (CRC), and is characterised by the loss of function of the MMR pathway. Failure to repair replication-associated errors due to a defective MMR system allows persistence of mismatch mutations all over the genome, but especially in regions of repetitive DNA known as microsatellites, giving rise to the phenomenon of microsatellite instability (MSI).

    Numerous studies have demonstrated that exercise acutely prevents the reduction in flow-mediated dilation induced by mental stress in subjects with metabolic syndrome (MetS). However, it is unknown whether a similar effect occurs in endothelial progenitors cells (EPCs). This study investigated whether exercise protects from the deleterious effect of mental stress on cultured EPCs in healthy subjects and those with MetS. Ten healthy subjects (aged 31±2) and ten subjects with MetS (aged 36±2) were enrolled. Subjects underwent a mental stress test, followed immediately by either 40 min of leg cycling or rest across two randomized sessions: mental stress+non-exercise control (MS) and mental stress+exercise (MS+EXE). The Stroop Color-Word Test was used to elicit mental stress. Blood samples were drawn at baseline and following sessions to isolate mononuclear cells. These cells were cultured in fibronectin-coated plates for seven days, and EPCs were identified by immunofluorescence (acLDL(+)/ UEA-I Lectin(+)). All subjects presented similar increases in mean blood pressure and heart rate during the mental stress test (P0.05). The EPC response to MS and MS+EXE was increased in healthy subjects, whereas it was decreased in subjects with MetS (Pexercise session increased EPCs in healthy subjects but did not prevent the EPC reduction induced by mental stress among subjects with MetS. © 2015.

    2014-01-01

    Background Physical activity is prescribed as a component of primary management for Polycystic Ovary Syndrome (PCOS). This study investigates the association between physical activity and mental health as well as the exercise barriers, motivators and support providers for younger women with and without PCOS to assist in physical activity uptake and prescription for these women. Methods Women aged 18-50 years with (n = 153) and without PCOS (n = 64) completed a questionnaire at one time point. The questionnaire included the Hospital Anxiety and Depression Scale and a survey regarding levels of physical activity, physical activity barriers, motivators and supports. A MANCOVA assessed associations between physical activity, PCOS and mental health (specifically depression and anxiety). Descriptive and Chi square goodness of fit statistics assessed the differences in perceived barriers, motivators and support providers amongst women with and without PCOS. Results Women with PCOS displayed higher severity of depression (F(1,210) = 8.32, p = 0.004) and anxiety (F(1,210) = 17.37, p motivated to be active to control a medical condition (Χ 2  = 7.48; p = 0.006). Women with PCOS identified more sources of support compared to women without PCOS. Conclusions Physical activity is associated with lower depression in women with PCOS and differences exist in the self-reported physical activity barriers, motivators and support providers, compared to controls. Being more active may offer mental health benefits in managing PCOS. Prescribing physical activity to women with PCOS should be individualized and consider both common and PCOS-specific barriers and motivators for successful engagement. PMID:24674140

    Leigh syndrome (LS) is a rare progressive neurodegenerative disorder occurring in infancy. The most common clinical signs reported in LS are growth retardation, optic atrophy, ataxia, psychomotor retardation, dystonia, hypotonia, seizures and respiratory disorders. The paper reported a manifestation of 3 Tunisian patients presented with LS syndrome. The aim of this study is the MT[HYPHEN]ATP6 and SURF1 gene screening in Tunisian patients affected with classical Leigh syndrome and the computational investigation of the effect of detected mutations on its structure and functions by clinical and bioinformatics analyses. After clinical investigations, three Tunisian patients were tested for mutations in both MT-ATP6 and SURF1 genes by direct sequencing followed by in silico analyses to predict the effects of sequence variation. The result of mutational analysis revealed the absence of mitochondrial mutations in MT-ATP6 gene and the presence of a known homozygous splice site mutation c.516-517delAG in sibling patients added to the presence of a novel double het mutations in LS patient (c.752-18 A > C/c. c.751 + 16G > A). In silico analyses of theses intronic variations showed that it could alters splicing processes as well as SURF1 protein translation.

    To clarify the effects of Zuoguiwan containing serum on osteoblast proliferation and alkaline phosphatase(ALP) expression and its effects on the expression of β-catenin, ERK1, ERK2 mRNA and protein of osteoblast through ERK1/2, Wnt/β-catenin signaling pathway in models with osteoporosis(OP) kidney-Yang-deficiency, osteoporosis(OP) kidney-Yin-deficiency syndrome. Rat osteoporosis models were established by ovariectomy surgery, and 10 weeks after surgery, hydrocortisone was injected and thyroxine was administered by intragastric administration to establish OP kidney-Yang-deficiency rat model, and OP kidney-Yin-deficiency rat model. Osteoblasts were obtained from 24 h newborn rat skull and were identified by alkaline phosphatase and alizarin red staining. Zuoguiwan containing serum of OP, OP kidney-Yang-deficiency, and OP kidney-Yin-deficiency, as well as the blank serum were used to intervene the osteoblast, and the cells proliferation was detected by MTS. ELISA assay was used to detect ALP expression. RT-PCR assay was used to detect the mRNA expression of ERK1, ERK2, β-catenin and protein expression levels were detected by Western blot. The results showed that Zuoguiwan containing serum in OP kidney-Yin-deficiency model had stronger effect than OP kidney-Yang-deficiency in promoting osteoblast proliferation, ALP expression, osteoblast ERK1/2, Wnt/β-catenin signaling pathway related factors β-catenin, ERK1, ERK2 mRNA and protein expression levels. This was consistent with the TCM theory of "Zuoguiwan nourishes kidney Yin", providing a scientific basis for the clinical and dialectical treatment of osteoporosis. Zuoguiwan could regulate the proliferation and differentiation of bone cells by ERK1/2 and Wnt/β-catenin signaling pathway, which may be one of the mechanisms of Zuoguiwan for the prevention of osteoporosis.

    Genetic syndromes with proportionate severe short stature are rare. We describe two sisters born to nonconsanguineous parents with severe linear growth retardation, poor weight gain, microcephaly, characteristic facial features, cutaneous syndactyly of the toes, high myopia, and severe intellectual disability. During infancy and early childhood, the girls had transient hepatosplenomegaly and low blood cholesterol levels that normalized later. A thorough evaluation including metabolic studies, radiological, and genetic investigations were all normal. Cholesterol metabolism and transport were studied and no definitive abnormality was found. No clinical deterioration was observed and no metabolic crises were reported. After due consideration of other known hereditary causes of post-natal severe linear growth retardation, microcephaly, and intellectual disability, we propose that this condition represents a newly recognized autosomal recessive multiple congenital anomaly-intellectual disability syndrome.

    One of the most discussed questions in clinical literature concerns the impact of child abuse by mentally ill parents (cf. Mattejat, 1998). It's obvious that most children cannot understand such a parental behaviour and that this lack of understanding along with the lack of knowledge about their parents' emotional disorder results in childrens' fear, disorientation and uncertainty. The consequences are massive interferences in the relationship between parents and children, who could develop an anxious-resistant insecure or even a disorganized/disoriented attachment. But how does a child react, if the behaviour of its parents is ambivalent itself and alternates from abuse to care? Such a parental behaviour is described as the "Munchausen by Proxy Syndrome". This article regards the effects of a "Munchausen by Proxy Syndrome" on the childrens' attachment development. After discussing the basic assumptions about the "Munchhauen by Proxy Syndrome" and the attachment theory we draw conclusions about the syndrome's effect on childrens' attachment behaviour.

    Full Text Available Introduction: Polycystic Ovary Syndrome (PCOS is among the common endocrine women disorders that can create manifestations such as anxiety and depression. In this study, the effect of aerobic training on mental health and depression among Iranian women suffering from PCOS has been examined. Methods: This semi experimental study was carried out based on pre-test and post-test on experiment and control groups in Arak, Iran. Twenty-two women with polycystic ovary syndrome (aged 27.82 ±5.23 yr were selected and randomly divided to training (n=12 and control (n=10 groups. Aerobic training program was performed 25-40 min/d, 3d/wk, for 10 weeks. Mental health and depression were evaluated using a general health questionnaire-28 (GHQ-28 and a Beck depression inventory (BAI-II in the two groups before and after the study. Results: The 10 week aerobic training had a significant effect on mental health, subscales of physical symptoms, anxiety and depression (p0.05. Conclusion: The result of present study suggests that aerobic exercise can improve the mental disorders in women with polycystic ovary syndrome.

    Marfan syndrome patients present important cardiac structural changes, ventricular dysfunction, and electrocardiographic changes. An abnormal heart rate response during or after exercise is an independent predictor of mortality and autonomic dysfunction. The aim of the present study was to compare heart rate recovery and chronotropic response obtained by cardiac reserve in patients with Marfan syndrome subjected to submaximal exercise. A total of 12 patients on β-blocker therapy and 13 off β-blocker therapy were compared with 12 healthy controls. They were subjected to submaximal exercise with lactate measurements. The heart rate recovery was obtained in the first minute of recovery and corrected for cardiac reserve and peak lactate concentration. Peak heart rate (141±16 versus 155±17 versus 174±8 bpm; p=0.001), heart rate reserve (58.7±9.4 versus 67.6±14.3 versus 82.6±4.8 bpm; p=0.001), heart rate recovery (22±6 versus 22±8 versus 34±9 bpm; p=0.001), and heart rate recovery/lactate (3±1 versus 3±1 versus 5±1 bpm/mmol/L; p=0.003) were different between Marfan groups and controls, respectively. All the patients with Marfan syndrome had heart rate recovery values below the mean observed in the control group. The absolute values of heart rate recovery were strongly correlated with the heart rate reserve (r=0.76; p=0.001). Marfan syndrome patients have reduced heart rate recovery and chronotropic deficit after submaximal exercise, and the chronotropic deficit is a strong determinant of heart rate recovery. These changes are suggestive of autonomic dysfunction.

    Thyroid hormone transport into cells requires plasma membrane transport proteins. Mutations in one of these, monocarboxylate transporter 8 (MCT8), have been identified as underlying cause for the Allan-Herndon-Dudley syndrome, an X-linked mental retardation in which the patients also present with abnormally high 3',3,5-triiodothyronine (T(3)) plasma levels. Mice deficient in Mct8 replicate the thyroid hormone abnormalities observed in the human condition. However, no neurological deficits have been described in mice lacking Mct8. Therefore, we subjected Mct8-deficient mice to a comprehensive immunohistochemical, neurological, and behavioral screen. Several behavioral abnormalities were found in the mutants. Interestingly, some of these behavioral changes are compatible with hypothyroidism, whereas others rather indicate hyperthyroidism. We thus hypothesized that neurons exclusively dependent on Mct8 are in a hypothyroid state, whereas neurons expressing other T(3) transporters become hyperthyroid, if they are exposed directly to the high plasma T(3). The majority of T(3) uptake in primary cortical neurons is mediated by Mct8, but pharmacological inhibition suggested functional expression of additional T(3) transporter classes. mRNAs encoding six T(3) transporters, including L-type amino acid transporters (LATs), were coexpressed with Mct8 in isolated neurons. We then demonstrated Lat2 expression in cultured neurons and throughout murine brain development. In contrast, LAT2 is expressed in microglia in the developing human brain during gestation, but not in neurons. We suggest that lack of functional complementation by alternative thyroid hormone transporters in developing human neurons precipitates the devastating neurodevelopmental phenotype in MCT8-deficient patients, whereas Mct8-deficient mouse neurons are functionally complemented by other transporters, for possibly Lat2.

  5. GLUT1 deficiency syndrome as a cause of encephalopathy that includes cognitive disability, treatment-resistant infantile epilepsy and a complex movement disorder.

    Graham, John M

    2012-05-01

    Glucose transporter-1 (GLUT1) deficiency syndrome is caused by heterozygous mutations in the SLC2A1 gene, resulting in impaired glucose transport into the brain. It is characterized by a low glucose concentration in the cerebrospinal fluid (hypoglycorrhachia) in the absence of hypoglycemia, in combination with low to normal lactate in the cerebrospinal fluid (CSF). It often results in treatment-resistant infantile epilepsy with progressive developmental disabilities and a complex movement disorder. Recognizing GLUT1 deficiency syndrome is important, since initiation of a ketogenic diet can reduce the frequency of seizures and the severity of the movement disorder. There can be a considerable delay in diagnosing GLUT1 deficiency syndrome, and this point is illustrated by the natural history of this disorder in a 21-year-old woman with severe, progressive neurological disabilities. Her encephalopathy consisted of treatment-resistant seizures, a complex movement disorder, progressive intellectual disability, and deceleration of her head growth after late infancy. Focused evaluation at age 21 revealed GLUT1 deficiency caused by a novel heterozygous missence mutation in exon 7 (c.938C > A; p.Ser313Try) in SLC2A1 as the cause for her disabilities.

    Clinical and molecular genetics have advanced current knowledge on genetic disorders associated with autism. A review of diverse genetic disorders associated with autism is presented and for the first time discussed extensively with regard to possible common underlying mechanisms leading to a similar cognitive-behavioral phenotype of autism. The possible role of interactions between genetic and environmental factors, including epigenetic mechanisms, is in particular examined. Finally, the pertinence of distinguishing non-syndromic autism (isolated autism) from syndromic autism (autism associated with genetic disorders) will be reconsidered. Given the high genetic and etiological heterogeneity of autism, autism can be viewed as a behavioral syndrome related to known genetic disorders (syndromic autism) or currently unknown disorders (apparent non-syndromic autism), rather than a specific categorical mental disorder. It highlights the need to study autism phenotype and developmental trajectory through a multidimensional, non-categorical approach with multivariate analyses within autism spectrum disorder but also across mental disorders, and to conduct systematically clinical genetic examination searching for genetic disorders in all individuals (children but also adults) with autism.

It highlights the need to study autism phenotype and developmental trajectory through a multidimensional, non-categorical approach with multivariate analyses within autism spectrum disorder but also across mental disorders, and to conduct systematically clinical genetic examination searching for genetic disorders in all individuals (children but also adults) with autism.

    Full Text Available As habilidades sociais vêm sendo amplamente reconhecidas como importante componente do processo de escolarização especialmente dos alunos com deficiência mental. A revisão da literatura evidencia escassez de pesquisas que focalizam a inclusão desses alunos no sistema regular de ensino. Considerando tal situação, este estudo teve como objetivos: avaliar e comparar o desempenho social (habilidades sociais e problemas de comportamento e acadêmico de alunos, com deficiência mental, incluídos, em relação a seus colegas de alto e baixo rendimento acadêmico (AR e BR, respectivamente. Trinta professores avaliaram 120 alunos (40 com deficiência mental incluídos no ensino regular, 40 AR e 40 AR da pré-escola à oitava série por meio do Sistema de Avaliação de Habilidades Sociais, na sua versão adaptada para o Brasil (SSRS-BR por BANDEIRA et al.

    Widespread hypovitaminosis D and an increased incidence of metabolic syndrome (MetS) represent significant problems of contemporary medicine but link between them remain unresolved. We aimed to define relationship between vitamin D serum concentration and exponents of MetS. The studies were conducted on 70 individuals (51 with and 19 without MetS). Concentrations of 25(OH)D (25-hydroxyergocalciferol and 25-hydroxycholecalciferol), calcium, cholesterol, HDL, cholesterol LDL, triglycerides, fasting glucose, blood pressure and anthropometric parameters were measured. Median concentration of vitamin D in the research population amounted to 41.46 nmol/L. Concentration of 25(OH)D in MetS group was lower than in remainder participants (38.45 nmol/L vs. 58.50 nmol/L, p = 0.0104). An inverse correlation was demonstrated between 25(OH)D level on one hand and body weight, waist and hips circumference, adipose body weight, Body Mass Index, Waist to Height Ratio (WHtR), glycaemia and number of MetS components on the other in persons free of MetS. No such relationships could be documented in MetS group. In the entire population values of Waist to Hip Ratio (WHpR) and WHtR indices manifested correlation with hyperglycaemia, hypertriglyceridaemia, low HDL concentrations. In persons without MetS a relationship was detected between vitamin D concentration and exponents of metabolic syndrome, although further studies on this problem are required.

  11. Hyponatremia in aneurysmal subarachnoid hemorrhage is due to the syndrome of inappropriate antidiuresis and acute glucocorticoid deficiency

    Hyponatraemia is the most common electrolyte abnormality following subarachnoid haemorrhage (SAH) and contributes to increased morbidity and mortality. Retrospective data suggests that the syndrome of inappropriate diuresis (SIAD) is the most common cause of hyponatraemia in SAH, though cerebral salt wasting has been postulated by some workers to be the predominant abnormality. Data which has shown acute glucocorticoid deficiency following SAH has suggested that some cases of euvolaemic hyponatraemia may also be caused by this mechanism.We prospectively studied the hormonal and haemodynamic influences involved in the development of hyponatraemia in 100 patients (61% female, median age 53 (range 16-82)) with non-traumatic aneurysmal SAH. Each patient had plasma sodium (pNa), urea, osmolality, glucose and 0900h cortisol (PC), and urinary sodium and osmolality measured on days 1, 2, 3, 4, 6, 8, 10 and 12 following SAH. Fluid balance and haemodynamic parameters were recorded daily. Results were compared with 15 patients admitted to ITU following vascular surgery. A PC<300nmol\\/L in a patient in ITU was regarded clinically as inappropriately low.49% of patients developed hyponatraemia (pNa<135 mmol\\/L), including 14% who developed clinically significantly hyponatraemia (pNa<130 mmol\\/L). 36\\/49 (73.4%) developed hyponatraemia between days 1 and 3 post SAH. The median duration of hyponatraemia was 3 days (range 1–10 days).In 35\\/49 (71.4%), hyponatraemia was due to SIAD as defined by standard diagnostic criteria. 14% of SAH patients had at least one PC<300nmol\\/L; 5 of these (35.7%) developed hyponatraemia. In 4 patients hyponatraemia was preceded by acute cortisol deficiency and responded to hydrocortisone treatment. In contrast, all controls had PC>500 nmol\\/L on day 1, and >300 nmol on days 3–12. There were no cases of cerebral salt wasting. There was no relationship between the incidence of hyponatraemia and the defined anatomical territory or severity of

    Joubert syndrome is a ciliopathy characterized by a specific constellation of central nervous system malformations that result in the pathognomonic "molar tooth sign" on imaging. More than 27 genes are associated with Joubert syndrome, but some patients do not have mutations in any of these genes. Celsr1, Celsr2, and Celsr3 are the mammalian orthologues of the drosophila planar cell polarity protein, flamingo; they play important roles in neural development, including axon guidance, neuronal migration, and cilium polarity. Here, we report bi-allelic mutations in CELSR2 in a Joubert patient with cortical heterotopia, microophthalmia, and growth hormone deficiency. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  13. Carnitine deficiency presenting with a decreased mental state in a patient with amyotrophic lateral sclerosis receiving long-term tube feeding: a case report.

    L-carnitine is an important metabolic mediator involved in fatty acid transport. It is obtained from the diet, particularly from animal products, such as red meat. Previous reports have revealed that long-term tube feeding with a commercial product containing no or low levels of carnitine can lead to an altered mental state caused by hyperammonemia. A 72-year-old Japanese man had a 12-year history of amyotrophic lateral sclerosis. He was bedridden and had required mechanical ventilation and enteral tube feeding for 10 years at home. His main enteral solution was a commercial product that contained low carnitine levels, and he sometimes received coffee and homemade products such as miso soup. Our patient's ability to communicate gradually deteriorated over a period of one year. His serum total carnitine level was abnormally low, at 26.7μmol/L (normal range, 45 to 91μmol/L), but his ammonium level was normal. His mental state improved dramatically after starting L-carnitine supplementation (600mg twice daily). This case highlights the importance of avoiding carnitine deficiency in patients with amyotrophic lateral sclerosis undergoing long-term tube feeding. These patients experience progressive muscle atrophy that might cause impaired carnitine storage and might manifest as communication difficulties. Carnitine deficiency can be misdiagnosed as a progression of systemic muscle atrophy. Clinicians should be aware of this disorder and should consider periodically measuring carnitine levels, regardless of the patient's serum ammonium levels.

    Physical activity is prescribed as a component of primary management for Polycystic Ovary Syndrome (PCOS). This study investigates the association between physical activity and mental health as well as the exercise barriers, motivators and support providers for younger women with and without PCOS to assist in physical activity uptake and prescription for these women. Women aged 18-50 years with (n = 153) and without PCOS (n = 64) completed a questionnaire at one time point. The questionnaire included the Hospital Anxiety and Depression Scale and a survey regarding levels of physical activity, physical activity barriers, motivators and supports. A MANCOVA assessed associations between physical activity, PCOS and mental health (specifically depression and anxiety). Descriptive and Chi square goodness of fit statistics assessed the differences in perceived barriers, motivators and support providers amongst women with and without PCOS. Women with PCOS displayed higher severity of depression (F(1,210) = 8.32, p = 0.004) and anxiety (F(1,210) = 17.37, p physically active women, depression was significantly less severe than in their inactive counterparts (F(2,210) = 13.62, p physical activity status and no interaction effects between PCOS and activity status for depression or anxiety. Women with PCOS were more likely to report a lack of confidence about maintaining physical activity (Χ2 = 3.65; p = 0.046), fear of injury (Χ2 = 4.08; p = 0.043) and physical limitations (Χ2 = 11.92; p = 0.001) as barriers to physical activity and were more likely to be motivated to be active to control a medical condition (Χ2 = 7.48; p = 0.006). Women with PCOS identified more sources of support compared to women without PCOS. Physical activity is associated with lower depression in women with PCOS and differences exist in the self-reported physical activity barriers, motivators and support providers, compared to controls

    Objective: To investigate the effects of qiangji jianli yin on hypothalamus CRH contents and plasma ACTH, Cortisol levels in rat models with kidney-yang deficiency syndrome. Methods: Rat models of kidney-yang deficiency syndrome were prepared with intramuscular injuection of hydroeortisone and divided into 5 groups: (1) no further treatment, n=13 (2) treated with high dosage d qiangji jiandi yin, n=12 (3) treated with medium dosage of qiangji jianli yin, n=12 (4) treated with low dosage of qiangji jianli yin n=12, (5) treated with yougui wan, n=12. Ten rats injuected with intramuscular distilled water only served as controls. The animals were sacrificied 14 days later and the hypothalamus CRH contents as well as plasma AOM and cortisol levels were measured with RIA. The thymus gland weight index and the adrenal gland index were calculated. Results: (1) The hypothalamus CRH contents and plasma ACTH, cortisol levels were significantly lower (P<0.01) in the rat models of kidney-yang deficiency syndrome without any treatment thas those in controls rats; the thymus and adrenal gland weight index were significantly decreased too (P <0.01). The CRH conteats and ACTH, cortisol levels in all the three group of rat model treated with different dosage of qiangji jianli yin were significantly higher than those in the models without any treatment (P<0.05-0.01). Conclusion: In rat models of kidney-yang deficiency syndrome, dysfunction of the hypothalamus-pituitary-adrenal axis (HPAA) led to decreased secretion of related hormones. The HPAA function might be partially restored with administation of qiangji jianli yin. (authors)

    Full Text Available Abstract Introduction Few cases of Epstein-Barr virus myelitis have been described in the literature. Multi-centric Castleman's disease is a lymphoproliferative disorder that is well known for its associations with the human immunodeficiency virus, human herpes virus 8, and Kaposi's sarcoma. The concurrent presentation of these two diseases in a patient at the same time is extremely unusual. Case Presentation We describe the case of a 43-year-old Caucasian man with acquired immune deficiency syndrome who presented with fever, weight loss and diffuse lymphadenopathy, and was diagnosed with multi-centric Castleman's disease. He presented three weeks later with lower extremity weakness and urinary retention, at which time cerebrospinal fluid contained lymphocytic pleocytosis and elevated protein. Magnetic resonance imaging demonstrated abnormal spinal cord signal intensity over several cervical and thoracic segments, suggesting the diagnosis of myelitis. Our patient was ultimately diagnosed with Epstein-Barr virus myelitis, as Epstein-Barr virus DNA was detected by polymerase chain reaction in the cerebrospinal fluid. Conclusion To the best of our knowledge, this is the first case of multi-centric Castleman's disease followed by acute Epstein-Barr virus myelitis in a human immunodeficiency virus-infected patient. Clinicians caring for human immunodeficiency virus-infected patients should be vigilant about monitoring patients with increasing lymphadenopathy, prompting thorough diagnostic investigations when necessary.

    Taking good care of elderly is a major challenge of our society, and thus identification of potential drug targets to reduce age-associated disease burden is desirable. α-klotho(-/-) (α-kl) is a short-lived mouse model that displays multiple phenotypes resembling human aging-related syndromes. Such ageing phenotype of α-kl(-/-) mice is associated with activation of a proteolytic enzyme, Calpain-1. We hypothesized that uncontrolled activation of calpain-1 might be causing age-related phenotypes in α-kl-deficient mice. We found that daily administration of BDA-410, a calpain-1 inhibitor, strikingly ameliorated multiple aging-related phenotypes. Treated mice showed recovery of reproductive ability, increased body weight, reduced organ atrophy, and suppression of ectopic calcifications, bone mineral density reduction, pulmonary emphysema and senile atrophy of skin. We also observed ectopic expression of FGF23 in calcified arteries of α-kl(-/-) mice, which might account for the clinically observed association of increased FGF23 level with increased risk of cardiovascular mortality. These findings allow us to propose that modulation of calpain-1 activity is a potential therapeutic option for delaying age-associated organ pathology, particularly caused by the dysregulation of mineral ion homeostasis.

    Fatty liver disease is commonly associated with obesity, insulin resistance and diabetes. Severe fatty liver is sometimes accompanied by steatohepatitis and may lead to the development of hepatocellular carcinoma. At present, there is no effective treatment for non-alcoholic fatty liver disease (NAFLD); thus, recent investigations have focused on developing effective therapeutics to treat this condition. This study aimed to evaluate the effects of kefir on the hepatic lipid metabolism of ob/ob mice, which are commonly used to model fatty liver disease. In this study, we used leptin receptor-deficient ob/ob mice as an animal disease model of NAFLD. Six-week-old ob/ob mice were orally administered the dairy product kefir (140 mg kg(-1) of body weight (BW) per day) for 4 weeks. The data demonstrated that kefir improved fatty liver syndrome on BW, energy expenditure and basal metabolic rate by inhibiting serum glutamate oxaloacetate transaminase (GOT) and glutamate pyruvate transaminase (GPT) activities (Pkefir administration also significantly reduced the macrovesicular fat quantity in liver tissue. In addition, kefir markedly decreased the expression of the genes sterol regulatory element-binding protein 1 (SREBP1), fatty acid synthase (FAS) and acetyl-CoA carboxylase (ACC) (Pkefir improves NAFLD on BW, energy expenditure and basal metabolic rate by inhibiting the lipogenesis pathway and that kefir may have the potential for clinical application to the prevention or treatment of NAFLD.

    Full Text Available Treatment outcomes from pallidal deep brain stimulation are highly heterogeneous reflecting the phenotypic and etiologic spectrum of dystonia. Treatment stratification to neurostimulation therapy primarily relies on the phenotypic motor presentation; however, etiology including genetic factors are increasingly recognized as modifiers of treatment outcomes. Here, we describe a 53 year-old female patient with a progressive generalized dystonia since age 25. The patient underwent deep brain stimulation of the globus pallidus internus (GPi-DBS at age 44. Since the clinical phenotype included mobile choreo-dystonic features, we expected favorable therapeutic outcome from GPi-DBS. Although mobile dystonia components were slightly improved in the long-term outcome from GPi-DBS the overall therapeutic response 9 years from implantation was limited when comparing “stimulation off” and “stimulation on” despite of proper electrode localization and sufficient stimulation programming. In order to further understand the reason for this limited motor symptom response, we aimed to clarify the etiology of generalized dystonia in this patient. Genetic testing identified a novel heterozygous pathogenic SLC2A1 mutation as cause of glucose transporter type 1 deficiency syndrome (GLUT1-DS. This case report presents the first outcome of GPi-DBS in a patient with GLUT1-DS, and suggests that genotype relations may increasingly complement phenotype-based therapy stratification of GPi-DBS in dystonia.

    Full Text Available Aim: To determine the prevalence of testosterone deficiency syndrome (TDS in healthy Indian men employed in a hospital aged above 40 years. Materials and Methods: A general medical health check-up camp was organized for all male employees above 40 years age working in surgical departments. After clinical history and systemic inquiry, subjects were requested to fill the St. Louis University′s ADAM Questionnaire based on which the total and free-serum testosterone estimation was then done. Results: One hundred fifty seven healthy volunteers enrolled for the study (mean age 53.1 years; range 40-60. The androgen decline in the aging male (ADAM Questionnaire detected 106 men (67.5% to be symptomatic for TDS. Serum testosterone estimation in these subjects revealed 41/106 to have low free-serum testosterone levels and 32/106 to have low total-serum testosterone. In 11 and 6 cases, respectively, the serum free- and total-testosterone levels were found to be low although the subjects were asymptomatic for TDS. Conclusions: The prevalence of symptomatic biochemical hypogonadism was 26.1%. The higher prevalence of symptoms alone of TDS was unusual. It could be because of the nature of the questionnaire. Free-serum testosterone may be a better single test to diagnose symptomatic hypogonadism than total-serum testosterone.

    Angelicae Sinensis Radix, with nourishing Yin, promoting blood circulation, and moisturizing dryness functions, is commonly used in clinical medicine. In order to investigate the effects and mechanism of Angelica sinensis(AS) on Th1/Th2 and Th17/Treg in mice with asthma and Yin deficiency syndrome, asthmatic and Yin deficiency syndrome Balb/c mice models were established by injecting and inhaling ovalbumin(OVA) and thyroxin. The models were treated with dexamethasone(DXM), AS extract and AS extract+DXM, respectively. Pathological examination of lung tissues was conducted by HE staining, and ELISA was used to detect the levels of IL-4, IL-17, IFN-γ, TGF-β as well as retinoic acid receptor-related orphan receptor (RORγt). Results showed that AS could significantly improve the situation of inflammation infiltration, increase ratios of IFN-γ/IL-4 and TGF-β/IL-17, decrease the levels of RORγt in lung tissues. The AS+DXM group showed a best treatment effect. The results indicated that AS played a therapeutic role for asthma with Yin deficiency syndrome and improved airway inflammation by inhibiting the expression of RORγt in lung tissues and regulating the balance of Th1/Th2 and Th17/Treg.

    Full Text Available Rett syndrome (RTT is a rare neurodevelopmental disorder, characterized by severe behavioural and physiological symptoms. Mutations in the methyl CpG binding protein 2 gene (MECP2 cause more than 95% of classic cases. Motor abnormalities represent a significant part of the spectrum of RTT symptoms. In the present study we investigated motor coordination and fine motor skill domains in MeCP2-308 female mice, a validated RTT model. This was complemented by the in vivo magnetic resonance spectroscopy (MRS analysis of metabolic profile in behaviourally relevant brain areas. MeCP2-308 heterozygous female mice (Het, 10-12 months of age were impaired in tasks validated for the assessment of purposeful and coordinated forepaw use (Morag test and Capellini handling task. A fine-grain analysis of spontaneous behaviour in the home-cage also revealed an abnormal handling pattern when interacting with the nesting material, reduced motivation to explore the environment, and increased time devoted to feeding in Het mice. The brain MRS evaluation highlighted decreased levels of bioenergetic metabolites in the striatal area in Het mice compared to controls. Present results confirm behavioural and brain alterations previously reported in MeCP2-308 males and identify novel endpoints on which the efficacy of innovative therapeutic strategies for RTT may be tested.

    Antenatal anaemia, iron deficiency and common mental disorders (CMD) are prevalent in low- and middle-income countries. The aim of this study was to examine the direct and indirect effects of antenatal exposures to these risks and infant motor development. A cohort of women who were pregnant with a single foetus and between 12 and 20 weeks pregnant in 50 randomly-selected rural communes in Ha Nam province was recruited. Participants provided data twice during pregnancy (early and late gestation) and twice after giving birth (8 weeks and 6 months postpartum). The Edinburgh Postnatal Depression Scale was used at all four data collection waves to detect CMD (score ≥ 4). Maternal anaemia (Hb anaemia was 21.5% in early pregnancy and 24.4% in late pregnancy. There was 4.1% iron deficiency at early pregnancy and 48.2% at late pregnancy. Clinically significant symptoms of CMD were apparent among 40% women in early pregnancy and 28% in late pregnancy. There were direct adverse effects on infant BSID-M scores at 6 months of age due to antenatal anaemia in late pregnancy (an estimated mean reduction of 2.61 points, 95% Confidence Interval, CI, 0.57 to 4.65) and CMD in early pregnancy (7.13 points, 95% CI 3.13 to 11.13). Iron deficiency and anaemia in early pregnancy were indirectly related to the outcome via anaemia during late pregnancy. Antenatal anaemia, iron deficiency, and CMD have a negative impact on subsequent infant motor development. These findings highlight the need to improve the quality of antenatal care when developing interventions for pregnant women that aim to optimise early childhood development in low- and middle-income countries.

    This paper presents clinical data on 41 patients (29 male and 12 female) from Haiti who presented with acquired immunedeficiency syndrome (AIDS). Their mean age was 32 years (range 17-61 years). 4 of thes cases were homosexual or bisexual; none was an illicit drug user or a hemophiliac. In addition, 3 of the female patients had sexual contact with a male partner with AIDS. 4 patients had received blood transfusions before their illness. The most prominent clinical symptom in this series was chronic diarrhea of 2-33 months' duration, which occurrred in 39 patients (95%). Also reporte were marked weight loss (95%), fatigue (95%), prolonger fever (90%), and nodular or maculopapular skin lesions (54%). Opportunistic infections in this series included oroesophageal candidiasis (88%) and intestinal cryptosporidiosis (31%). Tuberculosis developed in 22% of patients. Immunologic evaluation revealed profoundly depressed T-helper cells and an inverted T-helper/T-suppressor cell ratio. Biologic markers included elevated alpha-1 thymosin and beta-2 microglobulin levels, elevated immune complexes, and the presence of acid-labile interferon. Of interest were differences in the clinical expression of AIDS between this series and cases in the US. The Haitian data suggest a higher incidencs of female cases,a predominance of gastrointestinal symptoms rather than respiratory symptoms and lymphadenopathy, a frequent association with tuberculosis, and a relatively low incidence of Kaposi's sarcoma or P. carinii pneumonia compared to the situation in the US. As in the US, where most AIDS cases are concentrated in New York and California, most AIDS cases in Haiti are found in residents of Port-au-Prince and Carrefour, which are centers for male and female prostitution.

    The McDonough syndrome is a "new" MCA/MR syndrome which was found in 3 children (1 girl, 2 boys) of non-consanguineous parents. The affected children were mentally retarded (IQ 47--67) and had congenital heart defect, sternal deformity, kyphosis and craniofacila anomalies (anteverted auricles, upward slanted palpebral fissures, squint); cryptorchidism was present in the 2 boys. In addition a possible VFDP is postulated as the explanation for similar features in affected and unaffected siblings and parents. However, the McDonough syndrome may be an autosomal recessive trait with minor manifestations in heterozygotes. The klinefelter syndrome in one affected boy and a 46,XY/47,XXY chromosome constitution in the father was a coincidental finding.

    Full Text Available Objective  To screen non-classical 21-hydroxylase deficiency (NC-21OHD from patients diagnosed as polycystic ovary syndrome (PCOS by gene assay. Methods  Ninety-eight patients with PCOS were enrolled according to 2003 Rotterdam criteria from Department of Endocrinology, Tangdu Hospital of Fourth Military Medical University, and they were divided into three groups according to the modified Ferriman-Gallway (mF-G score as follows: group A with score 0-2; group B with score 3-5, and group C with score ≥6. Meanwhile, 30 healthy subjects from the Medical Center of the Hospital were recruited as control group. Peripheral blood of all subjects were collected for extracting DNA, the CYP21A2 gene were amplified by 5 pairs of specific primers, and then the PCR products were sequenced by Shanghai Sangon Co. The subjects would accept test for serum cortisol and adrenocorticotropic hormone (ACTH at 8:00am if their CYP21A2 was proved to be abnormal. Results  Thirty subjects of control group had no any defects in CYP21A2, but 5 of 98 patients with PCOS were proved to be deficient in CYP21A2, and the genotypes were V281L/920-921insT (P1, V281L/I230M (P2, V281L/Normal (P3, P4, P5, respectively, and all of them were heterozygous mutations. The incidences of NC-21OHD in group C and B were 28.6% and 3.3%, respectively. Genotype P1 had been identified to belong to NC-21OHD, which was consistent with its clinical phenotype. All genotypes P3, P4 and P5 belonged to carriers. But for P2, since I230M hadn't been reported in literature, the patient with V281L/I230M couldn't be classified now. Serum biochemical results showed that only in P1 the cortisol was close to the normal lower level, and ACTH was close to the normal upper limit of the reported level in the literature, and the remainders were all normal. Conclusions  Although PCOS and NC-21OHD are very similar in clinical manifestations, they are different completely in the pathogenesis and treatment. So it

    Full Text Available Abnormal behaviors involving dopaminergic gene polymorphisms often reflect an insufficiency of usual feelings of satisfaction, or Reward Deficiency Syndrome (RDS. RDS results from a dysfunction in the “brain reward cascade,” a complex interaction among neurotransmitters (primarily dopaminergic and opioidergic. Individuals with a family history of alcoholism or other addictions may be born with a deficiency in the ability to produce or use these neurotransmitters. Exposure to prolonged periods of stress and alcohol or other substances also can lead to a corruption of the brain reward cascade function. We evaluated the potential association of four variants of dopaminergic candidate genes in RDS (dopamine D1 receptor gene [DRD1]; dopamine D2 receptor gene [DRD2]; dopamine transporter gene [DAT1]; dopamine beta-hydroxylase gene [DBH]. Methodology: We genotyped an experimental group of 55 subjects derived from up to five generations of two independent multiple-affected families compared to rigorously screened control subjects (e.g., N = 30 super controls for DRD2 gene polymorphisms. Data related to RDS behaviors were collected on these subjects plus 13 deceased family members. Results: Among the genotyped family members, the DRD2 Taq1 and the DAT1 10/10 alleles were significantly (at least p < 0.015 more often found in the RDS families vs. controls. The TaqA1 allele occurred in 100% of Family A individuals (N = 32 and 47.8% of Family B subjects (11 of 23. No significant differences were found between the experimental and control positive rates for the other variants. Conclusions: Although our sample size was limited, and linkage analysis is necessary, the results support the putative role of dopaminergic polymorphisms in RDS behaviors. This study shows the importance of a nonspecific RDS phenotype and informs an understanding of how evaluating single subset behaviors of RDS may lead to spurious results.

    Traditional Chinese medicine formulates treatment according to body constitution (BC) differentiation. Different constitutions have specific metabolic characteristics and different susceptibility to certain diseases. This study aimed to assess the characteristic genes of gan-shen Yin deficiency constitution in different diseases. Fifty primary liver cancer (PLC) patients, 94 hypertension (HBP) patients, and 100 diabetes mellitus (DM) patients were enrolled and classified into gan-shen Yin deficiency group and non-gan-shen Yin deficiency group according to the body constitution questionnaire to assess the clinical manifestation of patients. The mRNA expressions of 17 genes in PLC patients with gan-shen Yin deficiency were different from those without gan-shen Yin deficiency. However, considering all patients with PLC, HBP, and DM, only MLH3 was significantly lower in gan-shen Yin deficiency group than that in non-gen-shen Yin deficiency. By ROC analysis, the relationship between MLH3 and gan-shen Yin deficiency constitution was confirmed. Treatment of MLH3 (-/- and -/+) mice with Liuweidihuang wan, classical prescriptions for Yin deficiency, partly ameliorates the body constitution of Yin deficiency in MLH3 (-/+) mice, but not in MLH3 (-/-) mice. MLH3 might be one of material bases of gan-shen Yin deficiency constitution.

    In the present study, we hypothesized that the enhancements obtained from the practice of jumping activity could be transferred to improve the walking balance in children with mental retardation (MR) and Down's syndrome (DS). Fourteen children with the diagnosis of MR or DS, aged 3 to 6 years, were recruited from a day care institution. They were ambulant but without jumping ability. Sixty-one non-handicapped children was used to serve as a normative comparison group. Before the training program, the performances of walking balance, jump skills and jumping distances were assessed individually by one physical therapist. The balance sub-test in the Bruininks Oseretsky Test of Motor Proficiency (BOTMP) was administered to assess the walking balance. Motor Skill Inventory (MSI) was used to assess the qualitative levels of jumping skills. A jumping skill training lesson that included horizontal jumps and vertical jumps was designed and integrated into the educational program. The recruited children received 3 sessions of training per-week for 6 weeks. A post-training test and a follow-up test were administered to the handicapped children. In BOTMP scores, statistical differences exited between the pre-training and post-training tests in the tested items of floor walk and beam walk. However, no significant difference was found in the items of floor stand, beam stand and floor heel-toe walk. MSI scales revealed there were significant differences between pre-training and post-training tests. There was no significant difference between the scores of post-training test and the follow-up test. The results implicated that the jumping activity might effectively evoke the automatic and dynamic postural control. Moreover, the significant improvements of the floor walk and beam walk performances might be due to the transferred effects via the practice of dynamic jumping activity. Furthermore, implications and suggestions are discussed.

    Full Text Available Background: There is an increased prevalence of metabolic syndrome (MetS in individuals with severe mental illness (SMI globally. The prevalence of MetS is higher in black women compared to black men from South Africa. Aim: To compare the prevalence of MetS between black South African men and women with SMI taking antipsychotic medication. Further, this prevalence was compared to the prevalence in a matched control group of black South African men and women without SMI. Setting: A general hospital psychiatric unit. Methods: A cross-sectional study was undertaken to compare the prevalence of MetS in a group of multi-ethnic participants with SMI treated with antipsychotic medication and a matched control group without SMI, applying the 2009 Joint Interim Statement (JIS criteria. Here, we included only the black African participants to compare MetS prevalence between men and women. Results: There were 232 participants in the group with SMI (male 155 and female 77 and without SMI (male 156 and female 76. The prevalence of MetS was more than three times higher in women with SMI compared to men with SMI (37.7% vs. 10.3%, p < 0.001. There was no significant difference in the prevalence of MetS in men or women between the groups with and without SMI. In multivariate logistic regression analysis, female gender (odds ratio [OR] 7.66, advancing age (OR 1.08 and longer duration of illness (OR = 1.15 were significant risk factors for MetS in SMI. Conclusion: In black South Africans with SMI on antipsychotic medication, there is a higher prevalence and risk for MetS in women compared to men.

    Studies have documented the impact that hurricanes have on mental health and injury rates before, during, and after the event. Since timely tracking of these disease patterns is crucial to disaster planning, response, and recovery, syndromic surveillance keyword filters were developed by the New York State Department of Health to study the short- and long-term impacts of Hurricane Sandy. Emergency department syndromic surveillance is recognized as a valuable tool for informing public health activities during and immediately following a disaster. Data typically consist of daily visit reports from hospital emergency departments (EDs) of basic patient data and free-text chief complaints. To develop keyword lists, comparisons were made with existing CDC categories and then integrated with lists from the New York City and New Jersey health departments in a collaborative effort. Two comprehensive lists were developed, each containing multiple subcategories and over 100 keywords for both mental health and injury. The data classifiers using these keywords were used to assess impacts of Sandy on mental health and injuries in New York State. The lists will be validated by comparing the ED chief complaint keyword with the final ICD diagnosis code. (Disaster Med Public Health Preparedness. 2017;11:173-178).

    Objective: To determine whether the SP-B deficiency and gene mutations in exon 4 is associated with neonatal RDS in China Han ethnic population. Methods: The study population consisted of 40 neonates with RDS and 40 neonates with other diseases as control in China Han ethnic population. We Compared SP-B expression in lung tissue and bronchoalveolar lavage fluid with immunoblotting, and analyzed mutations in the SP-B gene with polymerase chain reaction (PCR) and gene sequencing. Results: In RDS group, low mature Surfactant protein B was found in both lung tissue and bronchoalveolar lavage fluid in 8 neonates. In control group, only 4 neonates with low mature Surfactant protein B in both lung tissue and bronchoalveolar lavage fluid. In RDS group, 20 neonates were found to have mutations in exon 4, 12 homozygous mutations with C/C genotype and 8 heterozygous mutations with C/T genotype in surfactant protein B gene+1580 polymorphism. There were 8 cases mutations in control group, 1 in C/C and 7 in C/T genotype. The frequency of homozygotes with C/C genotype was 0.3 and frequency of heterozygotes with C/T genotype was 0.02 in RDS group. In control group, frequency of homozygotes with C/C genotype was 0.025 and frequency of heterozygote with C/T genotype was 0.175. Conclusion: Low mature Surfactant protein B is associated with the pathogenesis of neonatal respiratory distress syndrome (RDS) in China Han ethnic population. Mutations in exon 4 of the surfactant protein B gene demonstrate an association between homozygous mutations with C/C genotype in SP-B gene and neonatal RDS. PMID:23330012

    Full Text Available Background: South Africa is known to have one of the highest prevalence rates of human immunodeficiency virus (HIV and acquired immune deficiency syndrome (AIDS globally, with one in seven healthcare workers being HIV-positive. An HIV-positive healthcare workforce is less equipped to respond to the increasing spread of the epidemic. Objectives: Assessment of the factors contributing to high HIV prevalence rates among healthcare workers is important in planning the development of human resources. This review sought to identify and understand predominant risky sexual behaviours among healthcare workers in HIV and AIDS-affected countries. Methods: This study reviewed articles focusing on sexual behaviour among healthcare workers. Major health science databases (e.g. ProQuest, Cochrane, PubMed and CINAHL were searched for combinations of keywords including ‘healthcare workers’, ‘risky sexual behaviour’ and ‘HIV and AIDS’. Articles from a range of countries met inclusion and exclusion criteria. Results: Findings of the study revealed three main contributing factors: unprotected sex, multiple sex partners and sexual violence. Sexual violence emerged as the dominant risk factor in the majority of the studies. Most research was conducted in developed countries where the HIV infection rate is much lower than it is in developing countries. Conclusion: More research needs to be conducted in developing countries and appropriate strategies should be implemented to reduce sexual violence among healthcare workers. Appropriate procedures on reporting sexual violence coupled with education on HIV and AIDS as well as influencing attitudes and belief systems could assist in reducing the spread of HIV and AIDS within the healthcare workforce while minimising the effect on patient care.

    Early-onset inflammatory bowel diseases can result from a wide spectrum of rare mendelian disorders. Early molecular diagnosis is crucial in defining treatment and in improving life expectancy. Herein we aimed at defining the mechanism of an immunodeficiency-polyendrocrinopathy and enteropathy-X-linked (IPEX)-like disease combined with a severe immunodeficiency in 2 siblings born from distantly related parents. Whole exome sequencing was performed on blood-extracted genomic DNA from the 2 affected children and their parents on the genomic platform of Institut IMAGINE. Candidate gene mutation was identified using the in-house software PolyWeb and confirmed by Sanger sequencing. Protein expression was determined by western blot. Flow cytometry was used to assess consequences of the mutation on lymphocyte phenotype and nuclear factor-kappa B (NF-κB) activation at diagnosis and after treatment by hematopoietic stem cell transplantation. We identified a homozygous missense mutation in mucosa-associated lymphoid tissue lymphoma translocation 1 gene (MALT1), which precluded protein expression. In keeping with the known function of MALT1, NF-κB-dependent lymphocyte activation was severely impaired. Moreover, there was a drastic reduction in Forkhead box P3 (FOXP3) regulatory T cells accounting for the IPEX-like phenotype. Following identification of the mutation, both children received hematopoietic stem cell transplantation, which permitted full clinical recovery. Immunological workup at 6 and 12 months after transplantation showed normal NF-κB activation and correction of regulatory T cells frequency. Along with FOXP3, interleukin 2 receptor alpha chain (IL2RA), and cytotoxic T-lymphocyte protein 4 precursor (CTLA-4) mutations, MALT1 deficiency should now be considered as a possible cause of IPEX-like syndrome associated with immunodeficiency that can be cured by hematopoietic stem cell transplantation.

    Accuracy of risk algorithms for psychosis prediction in "at risk mental state" (ARMS) samples may differ according to the recruitment setting. Standardized criteria used to detect ARMS individuals may lack specificity if the recruitment setting is a secondary mental health service. The authors tested a modified strategy to predict psychosis conversion in this setting by using a systematic selection of trait-markers of the psychosis prodrome in a sample with a heterogeneous ARMS status. 138 non-psychotic outpatients (aged 17-31) were consecutively recruited in secondary mental health services and followed-up for up to 3 years (mean follow-up time, 2.2 years; SD=0.9). Baseline ARMS status, clinical, demographic, cognitive, and neurological soft signs measures were collected. Cox regression was used to derive a risk index. 48% individuals met ARMS criteria (ARMS-Positive, ARMS+). Conversion rate to psychosis was 21% for the overall sample, 34% for ARMS+, and 9% for ARMS-Negative (ARMS-). The final predictor model with a positive predictive validity of 80% consisted of four variables: Disorder of Thought Content, visuospatial/constructional deficits, sensory-integration, and theory-of-mind abnormalities. Removing Disorder of Thought Content from the model only slightly modified the predictive accuracy (-6.2%), but increased the sensitivity (+9.5%). These results suggest that in a secondary mental health setting the use of trait-markers of the psychosis prodrome may predict psychosis conversion with great accuracy despite the heterogeneity of the ARMS status. The use of the proposed predictive algorithm may enable a selective recruitment, potentially reducing duration of untreated psychosis and improving prognostic outcomes.

    What is a “mental illness”? What is an “illness”? What does the description and classification of “mental illnesses” actually involve, and is the description of “new” mental illnesses description of actually existing entities, or the creation of them?  “Solastalgia” is a neologism, invented by the Australian environmental philosopher Glenn Albrecht, to give greater meaning and clarity to psychological distress caused by environmental change (Albrecht et al 2007 The concept received some coverage in the international mass media in late 2007 (Thompson, 2007 Much of this described solastalgia as “a new concept in mental illness”, a description endorsed by Albrecht himself. The doctor and former British Foreign Secretary, Lord Owen, has coined the phrase “hubris syndrome” to describe the mindset of prime ministers and presidents whose behaviour is characterised by reckless, hubristic belief in their own rightness. This paper uses both the concept of solastalgia and the related concepts Albrecht posited of psychoterratic and somaterratic illnesses and hubris syndrome as a starting point to explore issues around the meaning of mental illness, and what it means to describe and classify mental illness.

    Classical Laron syndrome is a recessive disease of primary insulin-like growth factor 1 (IGF-1) deficiency and primary growth hormone insensitivity. Affected children have, among other defects, sparse hair growth and frontal recessions. The hair is thin and easy to pluck. Young adults have various degrees of alopecia, more pronounced in males. The aim of the present study was to investigate the effect of primary IGF-1 deficiency on hair structure. The study sample included 11 patients with Laron syndrome--5 children (2 untreated) and 6 adults (5 untreated). Hairs were examined by light and electron microscopy. The most significant structured defect, pili torti et canaliculi, was found in 2 young, untreated patients. Grooving, tapered hair and trichorrhexis nodosa were found in the remainder. IGF-1-treated patients had either none or significantly fewer pathological changes compared to the untreated patients. This is the first documentation of the role of primary IGF-1 deficiency on hair structure in human beings. Copyright 2004 S. Karger AG, Basel

    This paper reviews the scientific concepts and the clinical aspects of the burn-out syndrome. According to recent studies, up to 25 % of the German working population appear to suffer from what the Amercan physician and psychoanalyst, Herbert Freudenberger, has designated in 1974 as "burn-out syndrome". Characteristic features of this syndrome are emotional exhaustion, depersonalization and low personal accomplishment. People affected by the burn-out syndrome may suffer from depressive or anxious symptoms, from sleep disorders, chronic pain syndromes, or functional disorders of the cardiovascular or gastrointestinal system. Primary causes of the burnout syndrome include high demand combined with low influence, a high level of engagement without sufficient rewards or gratification, and a low level of social support. Preventive measures against burn-out include Balint-like supervision groups. In cases of a fully developed burn-out syndrome, affected persons should undergo either psychotherapy or a multimodal psychosomatic therapy.

    Constitutional mismatch repair deficiency (CMMRD) syndrome is a disorder with recessive inheritance caused by biallelic mismatch repair gene mutations, in which mismatch repair defects are inherited from both parents. This syndrome is associated with multiple cancers occurring in childhood. The most common tumors observed with CMMRD include brain tumors, digestive tract tumors, and hematological malignancies. The aim of this study was to report new phenotypic expressions of CMMRD syndrome and add new insight to the existing knowledge about this disease. A review of the literature was conducted and recommendation for surveillance and follow-up in patients with CMMRD are proposed. We report for the first time in the literature, the case of a 22-year-old female patient who was diagnosed with CMMRD syndrome, with the development of 2 unusual tumors: an anaplastic ganglioglioma and an osteosarcoma. She presented initially with an anaplastic ganglioglioma and later developed several malignancies including colonic adenocarcinoma, osteosarcoma, and acute myeloid leukemia. The patient had an atypical course of her disease with development of the initial malignancy at an older age and a remarkably long survival period despite developing aggressive tumors. Many aspects of this disease are still unknown. We identified a case of CMMRD in a patient presenting with an anaplastic ganglioglioma, who underwent successful surgical resection, chemotherapy, and radiotherapy and has had one of the longest survival periods known with this disease. This case broadens the tumor spectrum observed with CMMRD syndrome with anaplastic ganglioglioma and osteosarcoma as new phenotypic expressions of this genetic defect.

    Full Text Available Western diets are characterized by both dietary omega-3 fatty acid deficiency and increased fructose intake. The latter found in high amounts in added sugars such as sucrose and high fructose corn syrup (HFCS. Both a low intake of omega-3 fatty acids or a high fructose intake contribute to metabolic syndrome, liver steatosis or non-alcoholic fatty liver disease (NAFLD, promote brain insulin resistance, and increase the vulnerability to cognitive dysfunction. Insulin resistance is the core perturbation of metabolic syndrome. Multiple cognitive domains are affected by metabolic syndrome in adults and in obese adolescents, with volume losses in the hippocampus and frontal lobe, affecting executive function. Fish oil supplementation maintains proper insulin signaling in the brain, ameliorates NAFLD and decreases the risk to metabolic syndrome suggesting that adequate levels of omega-3 fatty acids in the diet can cope with the metabolic challenges imposed by high fructose intake in Western diets which is of major public health importance. This review presents the current status of the mechanisms involved in the development of the metabolic syndrome, brain insulin resistance, and NAFLD a most promising area of research in Nutrition for the prevention of these conditions, chronic diseases, and improvement of Public Health.

    Isolated glucocorticoid deficiency (IGD) is an autosomal recessive disorder characterized by primary adrenocortical insufficiency, usually without mineralocorticoid deficiency. Occasionally, the disorder is associated with alacrima and achalasia of the esophagus (triple A syndrome), suggesting potential heterogeneity in its etiology. Mutations in the ACTH receptor gene have been reported in several families with IGD. We have amplified and directly sequenced the entire intronless ACTH receptor gene in 1 other family with IGD and 2 famlies with triple A syndrome. The proband with IGD was a homozygote for an A {r_arrow}G substitution, changing tyrosine 254 to cysteine in the third extracellular loop of the receptor protein, probably interfering with ligand binding. Both of her parents were heterozygotes for this mutation, which was not detected in 100 normal alleles. No mutations were identified in the entire coding area of the ACTH receptor in the 2 families with triple A syndrome, supporting the idea of a developmental or postreceptor defect in this syndrome. 19 refs., 1 fig.

    Vitamin D has many immunomodulatory, anti-inflammatory, and neuroprotective functions, and previous studies have demonstrated an association between vitamin D deficiency and neuropsychiatric disease. The aim of our study was to analyze the prevalence of vitamin D deficiency in a 1-year cohort of adult inpatients with schizophreniform and autism spectrum syndromes in a naturalistic inpatient setting in Germany. Our study was comprised of 60 adult schizophreniform and 23 adult high-functioning autism spectrum patients who were hospitalized between January and December of 2015. We compared our findings with a historical German reference cohort of 3,917 adults using Pearson's two-sided chi-squared test. The laboratory measurements of 25-hydroxyvitamin D2/3 [25(OH)vitamin D] were obtained using a chemiluminescence immunoassay. In the schizophreniform group, we found decreased (vitamin D levels in 48/60 (80.0%) of the patients. In the autism spectrum group, decreased levels were detected in 18/23 (78.3%) of the patients. 25(OH)vitamin D deficiencies were found in 57.3% of the historical control group. Particularly, severe deficiencies (vitamin D values of >30 ng/ml were observed in only 5% of the schizophreniform patients, 8.7% of the autism spectrum patients, and 21.9% of the healthy controls. We found very high rates of 25(OH)vitamin D deficiencies in both patient groups and have discussed whether our findings might be related to alterations in the immunological mechanisms. Irrespective of the possible pathophysiological links between vitamin D deficiency and schizophrenia or autism spectrum disorders, a more frequent measurement of vitamin D levels seems to be justified in these patient groups. Further prospective, controlled, blinded, and randomized research should be conducted to analyze the effectiveness of vitamin D supplementation on the improvement of psychiatric symptoms.

    Burning mouth syndrome (BMS) is a disorder characterized by chronic mouth pain in the absence of objective clinical abnormalities. Vitamin or mineral deficiencies may have a role in BMS, but data regarding the prevalence and relevance of hematinic deficiencies are conflicting. We aimed to determine the frequency of specific laboratory abnormalities in patients with BMS. We retrospectively reviewed the results of screening blood tests in patients with BMS at our institution between January 2003 and December 2013. Among 659 patients with BMS, the most common decreased values or deficiencies were vitamin D 3 (15%), vitamin B 2 (15%), vitamin B 6 (5.7%), zinc (5.7%), vitamin B 1 (5.3%), thyrotropin (TSH) (3.2%), vitamin B 12 (0.8%), and folic acid (0.7%). Laboratory values for fasting blood glucose and TSH were increased in 23.7% and 5.2%, respectively. In patients with symptoms of BMS, our results suggest it is reasonable to screen for fasting blood glucose, vitamin D (D 2 and D 3 ), vitamin B 6 , zinc, vitamin B 1 , and TSH. Deficiencies of vitamin B 12 and folic acid were rare (<1% abnormal). © 2017 The International Society of Dermatology.

    Bannayan-Riley-Ruvalcaba syndrome (BRRS) is an autosomal dominant condition of macrocephaly in combination with lipomas/hemangiomas, hypotonia, developmental delay, and a lipid myopathy. The etiology of the lipid storage myopathy has been unclear. We describe a black boy with findings of BRRS who also has a defect in long-chain fatty acid oxidation expressed in cultured skin fibroblasts as a deficiency of long-chain-L-3-hydroxyacyl-CoA dehydrogenase (L-CHAD). He also has an abnormal brain MRI and increased size of both lower limbs. We present this child because of his unusual combination of findings, and postulate that L-CHAD deficiency may be the cause of the lipid myopathy in BRRS.

    An 11-month-old Border collie presented collapsed and continued to deteriorate rapidly despite supportive treatment. The dog had a history of failure to thrive and recurring respiratory infection. Laboratory abnormalities included neutrophilic leucocytosis, Heinz body anaemia, hyperammonaemia, hyperbilirubinaemia, proteinuria and hypocobalaminaemia. Post-mortem examination revealed multi-focal necrosis within the heart, kidneys, pancreas, liver, meninges and cerebral cortex. Fungal hyphae in lesions were identified as Scedosporium prolificans following culture. Subsequent genotyping confirmed that the dog carried the CUBN:c.8392delC mutation in a homozygous state, verifying hereditary cobalamin deficiency (a.k.a. Imerslund-Gräsbeck syndrome). Cobalamin deficiency may have been a predisposing factor for the development of systemic fungal infection in this dog. © 2017 British Small Animal Veterinary Association.

    Mental retardation (MR)/ intellectual disability (ID) is a neuro-developmental disorder characterized by a low intellectual quotient (IQ) and deficits in adaptive behavior related to everyday life tasks such as delayed language acquisition, social skills or self-help skills with onset before age 18. To date, a few genes (PRSS12, CRBN, CC2D1A, GRIK2, TUSC3, TRAPPC9, TECR, ST3GAL3, MED23, MAN1B1, NSUN1) for autosomal-recessive forms of non syndromic MR (NS-ARMR) have been identified and established in various families with ID. The recently reported candidate gene TRAPPC9 was selected for computational analysis to explore its potentially important role in pathology as it is the only gene for ID reported in more than five different familial cases worldwide. YASARA (12.4.1) was utilized to generate three dimensional structures of the candidate gene TRAPPC9. Hybrid structure prediction was employed. Crystal Structure of a Conserved Metalloprotein From Bacillus Cereus (3D19-C) was selected as best suitable template using position-specific iteration-BLAST. Template (3D19-C) parameters were based on E-value, Z-score and resolution and quality score of 0.32, -1.152, 2.30°A and 0.684 respectively. Model reliability showed 93.1% residues placed in the most favored region with 96.684 quality factor, and overall 0.20 G-factor (dihedrals 0.06 and covalent 0.39 respectively). Protein-Protein docking analysis demonstrated that TRAPPC9 showed strong interactions of the amino acid residues S(253), S(251), Y(256), G(243), D(131) with R(105), Q(425), W(226), N(255), S(233), its functional partner 1KBKB. Protein-protein interacting residues could facilitate the exploration of structural and functional outcomes of wild type and mutated TRAPCC9 protein. Actively involved residues can be used to elucidate the binding properties of the protein, and to develop drug therapy for NS-ARMR patients.

    Leigh syndrome (LS), or subacute necrotizing encephalomyelopathy, is a genetically heterogeneous, relentlessly progressive, devastating neurodegenerative disorder that usually presents in infancy or early childhood. A diagnosis of Leigh-like syndrome may be considered in individuals who do not fulfil the stringent diagnostic criteria but have features resembling Leigh syndrome.We describe a unique presentation of Leigh-like syndrome in a 3-year-old boy with elevated 3-hydroxyisovalerylcarnitine (C5-OH) on newborn screening (NBS). Subsequent persistent plasma elevations of C5-OH and propionylcarnitine (C3) as well as fluctuating urinary markers were suggestive of multiple carboxylase deficiency (MCD). Normal enzymology and mutational analysis of genes encoding holocarboxylase synthetase (HLCS) and biotinidase (BTD) excluded MCD. Biotin uptake studies were normal excluding biotin transporter deficiency. His clinical features at 13 months of age comprised psychomotor delay, central hypotonia, myopathy, failure to thrive, hypocitrullinemia, recurrent episodes of decompensation with metabolic keto-lactic acidosis and an episode of hyperammonemia. Biotin treatment from 13 months of age was associated with increased patient activity, alertness, and attainment of new developmental milestones, despite lack of biochemical improvements. Whole exome sequencing (WES) analysis failed to identify any other variants which could likely contribute to the observed phenotype, apart from the homoplasmic (100%) m.8993T>G variant initially detected by mitochondrial DNA (mtDNA) sequencing.Hypocitrullinemia has been reported in patients with the m.8993T>G variant and other mitochondrial disorders. However, persistent plasma elevations of C3 and C5-OH have previously only been reported in one other patient with this homoplasmic mutation. We suggest considering the m.8993T>G variant early in the diagnostic evaluation of MCD-like biochemical disturbances, particularly when associated with

    Full Text Available Abstract Background Severe mental illnesses (SMI may be independently associated with cardiovascular risk factors and the metabolic syndrome. We aimed to systematically assess studies that compared diabetes, dyslipidaemia, hypertension and metabolic syndrome in people with and without SMI. Methods We systematically searched MEDLINE, EMBASE, CINAHL & PsycINFO. We hand searched reference lists of key articles. We employed three search main themes: SMI, cardiovascular disease, and each cardiovascular risk factor. We selected cross-sectional, case control, cohort or intervention studies comparing one or more risk factor in both SMI and a reference group. We excluded studies without any reference group. We extracted data on: study design, cardiovascular risk factor(s and their measurement, diagnosis of SMI, study setting, sampling method, nature of comparison group and data on key risk factors. Results Of 14592 citations, 134 papers met criteria and 36 were finally included. 26 reported on diabetes, 12 hypertension, 11 dyslipidaemia, and 4 metabolic syndrome. Most studies were cross sectional, small and several lacked comparison data suitable for extraction. Meta-analysis was possible for diabetes, cholesterol and hypertension; revealing a pooled risk ratio of 1.70 (1.21 to 2.37 for diabetes and 1.11 (0.91 to 1.35 of hypertension. Restricting SMI to schizophreniform illnesses yielded a pooled risk ratio for diabetes of 1.87 (1.68 to 2.09. Total cholesterol was not higher in people with SMI (Standardized Mean Difference -0.10 (-0.55 to 0.36 and there were inconsistent data on HDL, LDL and triglycerides with some, but not all, reporting lower levels of HDL cholesterol and raised triglyceride levels. Metabolic syndrome appeared more common in SMI. Conclusion Diabetes (but not hypertension is more common in SMI. Data on other risk factors were limited by poor quality or inconsistent research findings, but a small number of studies show greater prevalence

  8. High-Throughput Screening to Identify Compounds That Increase Fragile X Mental Retardation Protein Expression in Neural Stem Cells Differentiated From Fragile X Syndrome Patient-Derived Induced Pluripotent Stem Cells.

    2015-07-01

    : Fragile X syndrome (FXS), the most common form of inherited cognitive disability, is caused by a deficiency of the fragile X mental retardation protein (FMRP). In most patients, the absence of FMRP is due to an aberrant transcriptional silencing of the fragile X mental retardation 1 (FMR1) gene. FXS has no cure, and the available treatments only provide symptomatic relief. Given that FMR1 gene silencing in FXS patient cells can be partially reversed by treatment with compounds that target repressive epigenetic marks, restoring FMRP expression could be one approach for the treatment of FXS. We describe a homogeneous and highly sensitive time-resolved fluorescence resonance energy transfer assay for FMRP detection in a 1,536-well plate format. Using neural stem cells differentiated from an FXS patient-derived induced pluripotent stem cell (iPSC) line that does not express any FMRP, we screened a collection of approximately 5,000 known tool compounds and approved drugs using this FMRP assay and identified 6 compounds that modestly increase FMR1 gene expression in FXS patient cells. Although none of these compounds resulted in clinically relevant levels of FMR1 mRNA, our data provide proof of principle that this assay combined with FXS patient-derived neural stem cells can be used in a high-throughput format to identify better lead compounds for FXS drug development. In this study, a specific and sensitive fluorescence resonance energy transfer-based assay for fragile X mental retardation protein detection was developed and optimized for high-throughput screening (HTS) of compound libraries using fragile X syndrome (FXS) patient-derived neural stem cells. The data suggest that this HTS format will be useful for the identification of better lead compounds for developing new therapeutics for FXS. This assay can also be adapted for FMRP detection in clinical and research settings. ©AlphaMed Press.

    Full Text Available Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type1 diabetes mellitus, hypothyroidism, adrenal insufficiency and vitiligo. LPS-responsive beige-like anchor protein (LRBA deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation. The third child of consanguineous Egyptian parents (Patient 1 presented at six months of age with intractable enteropathy and failure to thrive. Later on he developed symptoms of adrenal insufficiency, autoimmune haemolytic anaemia, thrombocytopenia, and infectious complications due to immunosuppressive treatment. The severe enteropathy was non-responsive to the standard treatment and led to death at the age of 22 years. His younger sister (Patient 2 presented at the age of 12 to the endocrinology department with decompensated hypothyroidism, perioral vitiligo, delayed pubertal development, and growth failure without enteropathy and immunodeficiency.Using whole-exome sequencing (WES we identified a homozygous frameshift mutation (c.6862delT, p.Y2288MfsX29 in the LRBA gene in both siblings. To our knowledge our patient (patient 2 is the first case of LRBA deficiency described with predominant endocrine phenotype without immunodeficiency and enteropathy. LRBA deficiency should be considered as underlying disease in pediatric patients presenting with autoimmune endocrine symptoms. The same genetic mutation can manifest with a broad phenotypic spectrum without genotype-phenotype correlation. The awareness for disease symptoms among non-immunologists might be a key to early diagnosis. Further functional studies in LRBA deficiency are necessary to

    To evaluate the association of vitamin D (VD) deficiency with gonadotropins and sex hormone in obese and non-obese women with polycystic ovary syndrome (PCOS). Of the total of 140 women, thirty obese and thirty nonobese, aged 20-40 years, were included in the study. Inclusion criteria were the women with normal level of thyroid-stimulating hormone (TSH), prolactin (PRL), parathyroid hormone (PTH), and calcium, and those who had not received any medication or VD supplementation within the last 6 months. Serum 25- hydroxyvitamin D (25(OH)D), C-reactive protein (CRP), lipid profile, fasting serum glucose, basal insulin, homeostasis model analysis of insulin resistance (HOMA-IR) index, follicle-stimulating hormone (FSH), luteinizing hormone (LH), oestrogen, total testosterone, dehidroepiandrostendion-sulphat (DHEA-S), androstendione, and sex hormone binding globulin (SHBG) were determined at follicular phase. Body mass index (BMI), weight, waist, lipids, and CRP were significantly higher in obese than in non-obese PCOS women (p=0.000). Meanwhile, insulin and HOMA-IR were also higher in the obese PCOS (p less than 0.000), and so was the fasting glucose (p=0.004). Furthermore, obese PCOS showed significantly higher level of LH (p=0.012), but lower level of progesterone (p=0.001) and androstendione (p=0.006) than in non-obese PCOS. In total 68% of PCOS women had VD deficiency but without significant difference among groups according to BMI. There was no association of VD deficiency with gonadotropins and sex hormones except SHBG. Insulin resistance was a better independent risk factor for the presence of vitamin D deficiency than SHBG. The insulin resistance and vitamin D deficiency significantly predicted the obesity risk in PCOS women.

    Adult neurogenesis is involved in certain hippocampus-dependent cognitive functions and is linked to psychiatric diseases including intellectual disabilities. The Coffin-Lowry syndrome (CLS) is a developmental disorder caused by mutations in the Rsk2 gene and characterized by intellectual disabilities associated with growth retardation. How RSK2-deficiency leads to cognitive dysfunctions in CLS is however poorly understood. Here, using Rsk2 Knock-Out mice, we characterized the impact of RSK2 deficiency on adult hippocampal neurogenesis in vivo. We report that the absence of RSK2 does not affect basal proliferation, differentiation and survival of dentate gyrus adult-born neurons but alters the maturation progression of young immature newborn neurons. Moreover, when RSK2-deficient mice were submitted to spatial learning, in contrast to wild-type mice, proliferation of adult generated neurons was decreased and no pro-survival effect of learning was observed. Thus, learning failed to recruit a selective population of young newborn neurons in association with deficient long-term memory recall. Given the proposed role of the dentate gyrus and of adult-generated newborn neurons in hippocampal-dependent pattern separation function, we explored this function in a delayed non-matching to place task and in an object-place pattern separation task and report severe deficits in spatial pattern separation in Rsk2-KO mice. Together, this study reveals a previously unknown role for RSK2 in the early stages of maturation and learning-dependent involvement of adult-born dentate gyrus neurons. These alterations associated with a deficit in the ability of RSK2-deficient mice to finely discriminate relatively similar spatial configurations, may contribute to cognitive dysfunction in CLS.

    To explore the impacts on physical and mental health of the patients with polycystic ovary syndrome (PCOS) treated with electroacupuncture (EA) or Diane 35. Seventy-two patients of PCOS were randomized into an acupuncture group and a western medication group, 36 cases in each group. In the acupuncture group, acupuncture was applied to relieving liver stagnation and regulating qi activity at Ganshu (BL 18), Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 4), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3). After qi arrival, the electric stimulation was added for 30 min. Acupuncture treatment was given 3 times a week. In the western medication group, Diane 35 was taken since the 5th day of menstruation and lasted for 21 days. The cycle of treatment was 3 months in the two groups. Before treatment and at the end of treatment, the symptom scores were evaluated and the self-report symptom inventory, symptom checklist-90 (SCL-90) was used for the mental health evaluation and the comparison was made between the two groups. Compared with those before treatment in the same group, the symptom scores were reduced significantly after treatment in the two groups (both P medication group (all P <0.05). EA with relieving liver stagnation and regulating qi activity reduces the symptom scores of PCOS and SCL-90 scores, acting on regulating both physical and mental conditions. The effects achieved with acupuncture are better than those with Diane 35.

    In this report we present data on cognitive development, language, behavior and social skills in 12 children and adolescents, nine girls and three boys, aged between 2.5 and 19 years, with Coffin-Siris syndrome (CS). 1. Mental retardation was mild in three patients and moderate in the nine others. 2. Speech onset was severely retarded with little interest in language. In the older group (seven patients aged 7 to 19 years), language comprehension was appropriate to the mental level. 3. Gross-motor functioning and autonomy, with the lowest score on "Task-orientation", were equal to the mental development. 4. Most frequently, aggressive disturbed behavior was observed, especially in the youngest children, while mixed disturbed behavior was observed in the oldest patients. Almost half of the CS patients (5/11) presented symptoms of pervasive developmental disorder, with 2/11 scoring in the pathological range. Obsessive interests, strong dependence on patterns and rituals and unusual fears were characteristic behavioral problems also when they got older.

    The Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE) are brief screening instruments for cognitive disorders. Although these instruments have frequently been used in the detection of dementia, there is currently little knowledge on the validity to detect Korsakoff's syndrome (KS) with both screening instruments. KS is a chronic neuropsychiatric disorder associated with profound declarative amnesia after thiamine deficiency. A representative sample of 30 patients with KS and 30 age-, education-, gender- and premorbid-IQ-matched controls was administered the MoCA and MMSE. The area under the receiver operating characteristic curve (AUC) was calculated in addition to the sensitivity, specificity, positive predictive value, and negative predictive value for various cut-off points on the MoCA and MMSE. Compared with the MMSE, the MoCA demonstrated consistently superior psychometric properties and discriminant validity--AUC: MoCA (1.00 SE .003) and MMSE (0.92 SE .033). When applying a cut-off value as suggested in the manuals of both instruments, the MMSE (< 24) misdiagnosed 46.7% of the patients, while the MoCA (< 26) diagnosed all patients correctly. As a screening instrument with the most optimal cut-offs, the MoCA (optimal cutoff point 22/23, 98.3% correctly diagnosed) was superior to the MMSE (optimal cutoff point 26/27, 83.3% correctly diagnosed). We conclude that both tests have adequate psychometric properties as a screening instrument for the detection of KS, but the MoCA is superior to the MMSE for this specific patient population.

    To compare the clinical efficacy differences between warming acupuncture and conventional acupuncture for diabetic peripheral neuropathy (DPN) with syndrome of yang deficiency and cold coagulation, obstruction of collaterals and blood stasis. A total of 64 patients were randomly divided into a warming acupuncture group and a conventional acupuncture group, 32 cases in each one. Based on basic treatment of blood glucose regulation, warming acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuanshu (BL 26), Zusanli (ST 36), Chongyang (ST 42), Quchi (LI 11) and Hegu (LI 4) in the warming acupuncture group, while acupuncture was applied at the identical acupoints in the conventional acupuncture group. Both the treatments were given once a day with an interval of one day every six days; totally the treatment was given for 4 weeks. The TCM symptom score, Toronto clinical scoring system (TCSS) and nerve conduction velocity (NCV) before and after treatment were compared in the two groups. After treatment, the TCM symptom scores in the two groups were significantly reduced (both P nervus peroneus communis, as well as sensory nerve of tibial nerve and sural nerve was improved in the warming acupuncture group (all P 0.05). Warming acupuncture and conventional acupuncture could both increase TCM symptom score, improve NCV in patients of DPN with syndrome of yang deficiency and cold coagulation, obstruction of collaterals and blood stasis; warming acupuncture has advantage in symptom improvement.

    Abstract Recent evidence has suggested that psychosis could develop not only in people at clinical high risk for psychosis (CHR-P) but also in those with clinical risk syndromes for emergent nonpsychotic mental disorders. The proportion of people with these clinical risk syndromes who will develop psychosis rather than to other nonpsychotic mental disorders is undetermined. Electronic databases were searched for studies reporting on clinical risk syndromes for the development of emergent nonpsychotic mental disorders. Incidence of emerging psychotic and nonpsychotic mental disorders defined on the ICD or DSM. Of a total of 9 studies relating to 3006 nonpsychotic at-risk individuals were included. Within prospective studies (n = 4, sample = 1051), the pooled incidence of new psychotic disorders across these clinical risk syndromes was of 12.9 per 1000 person-years (95% CI: 4.3 to 38.6) and that of nonpsychotic disorders (n = 3, sample = 538) was of 43.5 per 1000 person-years (95% CI: 30.9 to 61.3). Psychotic disorders may emerge outside the CHR-P paradigm, from clinical risk syndromes for incident nonpsychotic disorders, albeit at lower rates than in the CHR-P group. The clinical risk syndromes for emerging nonpsychotic disorders may exhibit a pluripotential risk of developing several types of mental disorders compared with CHR-P. If substantiated by future research, the current findings suggest that it may be useful to move beyond the current strategy of identifying individuals meeting CHR-P criteria only. PMID:29438561

    Iodine deficiency (IDD) is one of the common problem in the diet. Iodine deficiency as prevalence of goiter in population occurs in the mountainous areas. There is consensus that 800 million people are at risk of IDD from living in iodine deficient area and 190 million from goiter. Very high prevalence of IDD in different parts of the world are striking. It has generally observed that in iodine-deficient areas about 50% are affected with goiter, 1-5% from cretinsim and 20% from impaired mental and/or mortor function. (A.B.).

    Mutations of MAGEL2 have been reported in patients presenting with autism, and loss of MAGEL2 is also associated with Prader-Willi syndrome, a neurodevelopmental genetic disorder. This study aimed to determine the behavioral phenotype of Magel2-deficient adult mice, to characterize the central oxytocin (OT) system of these mutant mice, and to test the curative effect of a peripheral OT treatment just after birth. We assessed the social and cognitive behavior of Magel2-deficient mice, analyzed the OT system of mutant mice treated or not by a postnatal administration of OT, and determined the effect of this treatment on the brain. Magel2 inactivation induces a deficit in social recognition and social interaction and a reduced learning ability in adult male mice. In these mice, we reveal anatomical and functional modifications of the OT system and show that these defects change from birth to adulthood. Daily administration of OT in the first postnatal week was sufficient to prevent deficits in social behavior and learning abilities in adult mutant male mice. We show that this OT treatment partly restores a normal OT system. Thus, we report that an alteration of the OT system around birth has long-term consequences on behavior and on cognition. Importantly, an acute OT treatment of Magel2-deficient pups has a curative effect. Our study reveals that OT plays a crucial role in setting social behaviors during a period just after birth. An early OT treatment in this critical period could be a novel therapeutic approach for the treatment of neurodevelopmental disorders such as Prader-Willi syndrome and autism.

    Full Text Available Kabuki syndrome is a rare congenital anomaly, characterized by five fundamental features, the "Pentad of Niikawa": dysmorphic facies, skeletal anomalies, dermatoglyphic abnormalities, mild to moderate mental retardation and postnatal growth deficiency. Patients present characteristic external ocular features, nonetheless they may also present significant ocular abnormalities. We report a case of a brazilian child diagnosed with Kabuki syndrome, addressing the clinical features observed, with emphasis on the ocular manifestations. This case highlights the existence of this syndrome and all of its complexity. The identification of preventable causes of loss of vision underlines the value of detailed ophthalmologic examination of Kabuki syndrome patients.

    Cerebro-costo-mandibular syndrome is a rare disorder characterized by rib malformations, various degrees of cerebral maldevelopment, mental deficiency, palatal defects, and micrognatia. This syndrome was first described in 1966. The majority of cases are sporadic, but a few instances of familial occurrence have been reported, some with an autosomal recessive pattern of inheritance. Mortality in early age has been high, probably mostly due to respiratory insufficiency secondary to rib abnormalities and flail chest. We report a mother and son with this disorder, suggesting autosomal dominant transmission. (orig.)

    Wernicke encephalopathy can have different clinical outcomes. Although infections may precipitate the encephalopathy itself, it is unknown whether infections also modify the long-term outcome in patients developing Korsakoff syndrome. To determine whether markers of infection, such as white blood cell (WBC) counts and absolute neutrophil counts in the Wernicke phase, are associated with cognitive outcomes in the end-stage Korsakoff syndrome. Retrospective, descriptive study of patients admitted to Slingedael Korsakoff Center, Rotterdam, The Netherlands. Hospital discharge letters of patients with Wernicke encephalopathy were searched for relevant data on infections present upon hospital admission. Patients were selected for further analysis if data were available on WBC counts in the Wernicke phase and at least 1 of 6 predefined neuropsychological tests on follow-up. Infections were reported in 35 of 68 patients during the acute phase of Wernicke-Korsakoff syndrome-meningitis (1), pneumonia (14), urinary tract infections (9), acute abdominal infections (4), sepsis (5) empyema, (1) and infection "of unknown origin" (4). The neuropsychological test results showed significant lower scores on the Cambridge Cognitive Examination nonmemory section with increasing white blood cell counts (Spearman rank correlation, ρ = -0.34; 95% CI: -0.57 to -0.06; 44 patients) and on the "key search test" of the behavioral assessment of the dysexecutive syndrome with increasing absolute neutrophil counts (ρ= -0.85; 95% CI: -0.97 to -0.42; 9 patients). Infections may be the presenting manifestation of thiamine deficiency. Patients with Wernicke-Korsakoff syndrome who suffered from an infection during the acute phase are at risk of worse neuropsychological outcomes on follow-up.

    2004-03-01

    Full Text Available Abstract Background Zellweger syndrome (ZS is a fatal inherited disease caused by peroxisome biogenesis deficiency. Patients are characterized by multiple disturbances of lipid metabolism, profound hypotonia and neonatal seizures, and distinct craniofacial malformations. Median live expectancy of ZS patients is less than one year. While the molecular basis of peroxisome biogenesis and metabolism is known in considerable detail, it is unclear how peroxisome deficiency leads to the most severe neurological symptoms. Recent analysis of ZS mouse models has all but invalidated previous hypotheses. Hypothesis We suggest that a regulatory rather than a metabolic defect is responsible for the drastic impairment of brain function in ZS patients. Testing the hypothesis Using microarray analysis we identify diazepam binding inhibitor/acyl-CoA binding protein (DBI as a candidate protein that might be involved in the pathogenic mechanism of ZS. DBI has a dual role as a neuropeptide antagonist of GABA(A receptor signaling in the brain and as a regulator of lipid metabolism. Repression of DBI in ZS patients could result in an overactivation of GABAergic signaling, thus eventually leading to the characteristic hypotonia and seizures. The most important argument for a misregulation of GABA(A in ZS is, however, provided by the striking similarity between ZS and "benzodiazepine embryofetopathy", a malformation syndrome observed after the abuse of GABA(A agonists during pregnancy. Implications of the hypothesis We present a tentative mechanistic model of the effect of DBI misregulation on neuronal function that could explain some of the aspects of the pathology of Zellweger syndrome.

    Mental Retardation (MR) is the most frequent handicap. It touches 3% of the general population. The genetic causes of this handicap account for 40% of these cases. ARX gene (Aristaless related homeobox gene) belongs to the family of the genes homeobox located in Xp22.1. It is considered as the most frequently muted gene after the FMR1 gene. It is implicated in various forms of syndromic and nonsyndromic MR. Several types of mutation were identified on the level of this gene, including deletions/insertions, duplications, missense and nonsense mutations, responsible for a wide spectrum of phenotypes. The goal of this work is to seek the most frequent change of gene ARX: duplication 24pb (at the origin of an expansion of the field poly has protein ARX in the position 144-155AA) among Tunisian boys presenting in particular family forms of non specific MR, sporadic forms of non specific MR like certain patients presenting a West syndrome.To prove the duplication of 24 Pb, we used in this work the Pcr technique. The change of duplication 24pb was not found in our series, this could be explained by the low number of cases family studied (38 families) and by the absence of connection studies accusing a mode of transmission related to X chromosome in particular for the sporadic cases.

    Vitamin D deficiency is highly prevalent all over the world and dietary intakes of vitamin D are very low in China. In this study we aimed to determine whether vitamin D deficiency is associated with increased risk of metabolic syndrome (MetS) among Chinese type 2 diabetes mellitus (T2DM) patients aged over 50 y. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were measured in a cross-sectional sample of 270 T2DM patients aged over 50 y from Zhejiang. Data on demographic characteristics, anthropometry and other variables were collected. The mean of serum 25(OH)D was 22.93 ng/mL, and percentages of vitamin D deficiency and insufficiency were 43.71% and 39.63%, respectively. Serum 25(OH)D concentrations were significantly lower in subjects with MetS than in those without MetS (21.74 vs 24.96 ng/mL, p=0.001), and the prevalence of MetS significantly increased according to tertiles of serum 25(OH)D concentrations. After adjusting for multivariate factors, the adverse effect of lower serum 25(OH)D concentrations was significant (OR: 3.26, 95% CI: 1.03-7.34; p=0.044) in the group with BMI≥24 kg/m 2 while the change in OR of MetS for each 10 ng/mL decrease in the serum 25(OH)D concentrations was 2.03 (95% CI: 1.10-3.79). These results suggest that serum 25(OH)D deficiency may be a risk factor of MetS among Chinese type 2 diabetic patients, especially in the T2DM with BMI≥24 kg/m 2 . The challenge is determining the mechanisms of vitamin D action for recommendation of vitamin D supplementation that reduces the risks of MetS and progression to T2DM.

    Hermansky-Pudlak syndrome (HPS) is an autosomal recessive disease consisting of oculocutaneous albinism and a storage pool deficiency resulting from absent platelet dense bodies. The disorder is genetically heterogeneous. The majority of patients, including members of a large genetic isolate in northwest Puerto Rico, have mutations in HPS1. Another gene, ADTB3A, was shown to cause HPS-2 in two brothers having compound heterozygous mutations that allowed for residual production of the gene product, the beta3A subunit of adaptor complex-3 (AP-3). This heterotetrameric complex serves as a coat protein-mediating formation of intracellular vesicles, e.g. the melanosome and platelet dense body, from membranes of the trans-Golgi network. We determined the genomic organization of the human ADTB3A gene, with intron/exon boundaries, and describe a third patient with beta3A deficiency. This 5-y-old boy has two nonsense mutations, C1578T (R-->X) and G2028T (E-->X), which produce no ADTB3A mRNA and no beta3A protein. The associated mu3 subunit of AP-3 is also entirely absent. In fibroblasts, the cell biologic concomitant of this deficiency is robust and aberrant trafficking through the plasma membrane of LAMP-3, an integral lysosomal membrane protein normally carried directly to the lysosome. The clinical concomitant is a severe, G-CSF-responsive neutropenia in addition to oculocutaneous albinism and platelet storage pool deficiency. Our findings expand the molecular, cellular, and clinical spectrum of HPS-2 and call for an increased index of suspicion for this diagnosis among patients with features of albinism, bleeding, and neutropenia.

    Full Text Available Introduction: Vitamin D has many immunomodulatory, anti-inflammatory, and neuroprotective functions, and previous studies have demonstrated an association between vitamin D deficiency and neuropsychiatric disease. The aim of our study was to analyze the prevalence of vitamin D deficiency in a one-year cohort of adult inpatients with schizophreniform and autism-spectrum syndromes in a naturalistic in-patient setting in Germany. Participants and methods: Our study was comprised of 60 adult schizophreniform and 23 adult high-functioning autism spectrum patients who were hospitalized Page: 2between January and December of 2015. We compared our findings with a historical German reference cohort of 3,917 adults using Pearson’s two-sided chi-squared test. The laboratory measurements of 25-hydroxyvitamin D2/3 (25(OHvitamin D were obtained using a chemiluminescence immunoassay. Results: In the schizophreniform group, we found decreased ( 30 ng/ml were observed in only 5% of the schizophreniform patients, 8.7% of the autism spectrum patients, and 21.9% of the healthy controls. Discussion: We found very high rates of 25(OHvitamin D deficiency in both patient groups, and have discussed whether our findings might be related to alterations in the immunological mechanisms. Irrespective of the possible pathophysiological links between vitamin D deficiency and schizophrenia or autism spectrum disorders, a more frequent measurement of vitamin D levels seems to be justified in these patient groups. Further prospective, controlled, blinded, and randomized research should be conducted to analyze the effectiveness of vitamin D supplementation on the improvement of psychiatric symptoms.

    Full Text Available BACKGROUND Under nutrition is one of the major problems in the field of Paediatrics. The greatest risk of malnutrition is in the first two years of life. The effects of this early damage on health, brain development, intelligence, educability and productivity are potentially reversible. The current study was an attempt to find out the clinico epidemiological profile, evaluate them for trace elements deficiency and most appropriate management options in those who are admitted with infantile tremor syndrome. MATERIALS AND METHODS The current study was a hospital based cross sectional study that was conducted in the Department of Paediatrics, Dr. S. N. Medical College Jodhpur. Duration of study was One Year. Any child up to the age of three years of age admitted in the paediatric wards with typical features of infantile tremor syndrome. RESULTS Maximum numbers of patients were found between 6 months to 12 months of age, there was slight male predominance. The majority of infants in our study (85% were exclusively breast fed, 66% of cases were having low serum Copper level. 9% of cases were having low serum zinc level. 8% of cases were having low serum copper level with tremors. CONCLUSION In our study the fact that NTS is mainly seen in children who are exclusively breast feed for a longer period with delayed introduction of weaning foods. The main presenting features remain developmental delay, hyper pigmentation and anemia. Among nutritional factors, deficiency of copper and zinc in children plays a big role in development of disease. Thus to prevent the development of nutritional tremor syndrome stress should be on early timely introduction of weaning foods, especially rich in copper and zinc. What is already known about this Study- low levels of trace elements like copper and zinc may be responsible for typical clinical manifestations in patients of infantile tremor syndrome. Pronged and Exclusive breast feeding further aggravate these features

Nearly 40% of the IBS group (versus 20% of the controls reached a clinically relevant value on the SCL-90-R global severity scale. IBS subtypes did not differ in terms of mental distress or chronic stress. Somatization, anxiety, and the chronic stressors “work overload,” “social tension,” and “dissatisfaction with job” were most closely connected to IBS symptom severity. Regarding health care utilization, our results show that consulting a physician frequently was not associated significantly with elevated mental strain or chronic stress but with IBS symptom severity. Conclusion. Our data contribute additional evidence to the distinct association between psychological stress and IBS in community samples.

    Full Text Available Abstract Introduction Thrombotic thrombocytopenic purpura-hemolytic uremic syndrome is a life-threatening condition with various etiopathogeneses. Without therapy approximately 90% of all patients die from the disease. Case presentation We report the case of a 17-year-old Caucasian woman with widespread hematomas and headache. Due to hemolytic anemia, thrombocytopenia, and schistocytosis, thrombotic thrombocytopenic purpura-hemolytic uremic syndrome was suspected and plasma exchange therapy was initiated immediately. Since her thrombocyte level did not increase during the first week of therapy, plasma treatment had to be intensified to a twice-daily schedule. Further diagnostics showed markedly reduced activities of both ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13 - also known as von Willebrand factor-cleaving protease and factor H. Test results for antibodies against both proteins were positive. While plasma exchange therapy was continued, rituximab was given once weekly for four consecutive weeks. After the last dose, thrombocytes and activities of ADAMTS-13 and factor H increased into the normal range. Our patient improved and was discharged from the hospital. Conclusions Since no clinical symptoms/laboratory findings indicated a malignant or specific autoimmune-mediated disorder, the diagnosis made was thrombotic thrombocytopenic purpura-hemolytic uremic syndrome due to idiopathic combined, autoantibody-mediated ADAMTS-13/factor H deficiency.

  17. Mozart at play: the limitations of attributing the etiology of genius to tourette syndrome and mental illness.

    2015-01-01

    There has been a persistent attempt to explain Mozart's talent as connected to physical and mental illness. While Mozart's musical compositions and performances were often acclaimed for their "taste," the composer's personal behavior sometimes astonished those who witnessed "blödeln" or wild horseplay, practical joking, and scatological humor. Most recently, Mozart's eccentric behavior has been attributed to Gilles de la Tourette syndrome. This chapter investigates the evidence for these retrospective diagnoses and reassesses this evidence by paying particular attention to the milieu in which Mozart lived. We argue that Mozart's putative pathological behavior was a manifestation of his resilience in face of multiple adversities and was deeply rooted in his sense of play. Our hypothesis is that play, rather than neuropsychiatric disease, was essential to the operation of his genius. © 2015 Elsevier B.V. All rights reserved.

    The relationship between mental retardation and brain size is discussed. Research suggests that a common path for many otherwise idiopathic mild retardation cases (genetic or environmental) could be small brain size, indicating reduced information processing capacity. Suggestions are made for further research on neuron number. (SLD)

    The fragile X mental retardation (FXMR) syndrome is one of the most frequent causes of mental retardation. Affected individuals display a wide range of additional characteristic features including behavioural and physical phenotypes, and the extent to which individuals are affected is highly variable. For these reasons, elucidation of the pathophysiology of this disease has been an important challenge to the scientific community. 1991 marks the year of the discovery of both the FMR1 gene mutations involved in this disease, and of their dynamic nature. Although a mouse model for the disease has been available for 16 years and extensive research has been performed on the FMR1 protein (FMRP), we still understand little about how the disease develops, and no treatment has yet been shown to be effective. In this review, we summarise current knowledge on FXMR with an emphasis on the technical challenges of molecular diagnostics, on its prevalence and dynamics among populations, and on the potential of screening for FMR1 mutations.

  4. A qualitative exploration of physical, mental and ocular fatigue in patients with primary Sjögren's Syndrome.

    Directory of Open Access Journals (Sweden)

    Rebecca J Stack

    Full Text Available Primary Sjögren's Syndrome (pSS affects exocrine glands such as those producing the tear film, leading to dry and painful eyes, but is also associated with fatigue. The experience of fatigue in pSS, and its relationship with sicca symptoms, is poorly understood.Twenty people diagnosed with pSS were recruited to participate in a semi-structured qualitative interview about their symptoms experience. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.People with pSS described physical tiredness, mental fatigue and ocular fatigue. Mental fatigue was characterised by difficulties in attention, particularly, the ability to follow conversations and short-term memory problems. Participants linked their experience of fatigue to feeling of depression, frustration, irritation and anxiety, and therefore, fatigue was suggested to have had a large impact on their psychological well-being. People with pSS also described a range of ocular symptoms including pain, dryness, and itching, which were compounded by fatigue. For some, eye fatigue was pervasive, and daily activities involving the eyes such as reading, using the computer and driving were impaired. In some cases, the level of ocular discomfort was so severe it prevented sleep, which in turn impacted on general fatigue levels.People with pSS experience fatigue in a range of ways; physical, mental and ocular fatigue were described. Fatigue was suggested to exacerbate other ocular symptoms, posed serious physical limitations and caused psychological distress. Further research into the nature of fatigue and ocular symptoms in pSS is required.

    Full Text Available Summary: Transcriptional analysis of brain tissue from people with molecularly defined causes of obesity may highlight disease mechanisms and therapeutic targets. We performed RNA sequencing of hypothalamus from individuals with Prader-Willi syndrome (PWS, a genetic obesity syndrome characterized by severe hyperphagia. We found that upregulated genes overlap with the transcriptome of mouse Agrp neurons that signal hunger, while downregulated genes overlap with the expression profile of Pomc neurons activated by feeding. Downregulated genes are expressed mainly in neuronal cells and contribute to neurogenesis, neurotransmitter release, and synaptic plasticity, while upregulated, predominantly microglial genes are involved in inflammatory responses. This transcriptional signature may be mediated by reduced brain-derived neurotrophic factor expression. Additionally, we implicate disruption of alternative splicing as a potential molecular mechanism underlying neuronal dysfunction in PWS. Transcriptomic analysis of the human hypothalamus may identify neural mechanisms involved in energy homeostasis and potential therapeutic targets for weight loss. : Prader-Willi syndrome (PWS is a genetic obesity syndrome. Bochukova et al. report gene expression changes in the hypothalamus of people with PWS that support neurodegeneration and neuroinflammation as key processes involved in this condition.

    Creatine synthesis and transport disorders, Triple H syndrome and ornithine transcarbamylase deficiency are treatable inborn errors of metabolism. Early screening of patients was found to be beneficial. Mass spectrometry analysis of specific urinary biomarkers might lead to early detection and treatment in the neonatal period. We developed a high-throughput mass spectrometry methodology applicable to newborn screening using dried urine on filter paper for these aforementioned diseases. A high-throughput methodology was devised for the simultaneous analysis of creatine, guanidineacetic acid, orotic acid, uracil, creatinine and respective internal standards, using both positive and negative electrospray ionization modes, depending on the compound. The precision and accuracy varied by screening for inherited disorders by biochemical laboratories. Copyright © 2014 Elsevier B.V. All rights reserved.

    Iron deficiency (ID) is a prevalent condition in patients with ischemic heart disease and heart failure. Little is known about the impact of ID on exercise capacity and quality of life (QoL) in the recovery phase after an acute coronary syndrome (ACS). Iron status and its impact on exercise capacity and QoL were prospectively evaluated in 244 patients 30 days after the ACS. QoL was assessed by the standard EuroQoL-5 dimensions, EuroQoL visual analogue scale, and Heart-QoL questionnaires. Exercise capacity was analyzed by treadmill/6-minute walk tests. The effect of ID on cardiovascular mortality and readmission rate was also investigated. A total of 46% of the patients had ID. These patients had lower exercise times (366±162 vs 462±155seconds; Pde Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

    Henan Province in China has a major epidemic of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). Chinese medicine (CM) has been used throughout the last decade, and a management modality was developed, which can be described by unified-planning, graded-administration, and centralized-controlling (UGC). The UGC modality has one primary concept (patient-centered medicine from CM theory), four basic foundations (classifying administrative region, characteristics of CM on disease treatment, health resource conditions, and distribution of patients living with HIV), six important relationships (the "three uniformities and three combinations," and the six relationships therein guide the treatment of AIDS with CM), and four key sections (management, operation, records, and evaluation). In this article, the authors introduce the UGC modality, which could be beneficial to developing countries or resource-limited areas for the management of chronic infectious disease.

    We report on 11 patients from 8 families with a blepharophimosis and mental retardation syndrome (BMRS) phenotype. Using current nosology, five sporadic patients have Ohdo syndrome, associated with congenital hypothyroidism in two of them (thus also compatible with a diagnosis of Young-Simpson syndrome). In two affected sibs with milder phenotype, compensated hypothyroidism was demonstrated. In another family, an affected boy was born to the unaffected sister of a previously reported patient. Finally, in the last sibship, two affected boys in addition had severe microcephaly and neurological anomalies. A definitive clinical and etiologic classification of BMRS is lacking, but closer phenotypic analysis should lead to a more useful appraisal of the BMRS phenotype. We suggest discontinuing the systematic use of the term "Ohdo syndrome" when referring to patients with BMRS. We propose a classification of BMRS into five groups: (1) del(3p) syndrome, (possibly overlooked in older reports); (2) BMRS, Ohdo type, limited to the original patients of Ohdo; (3) BMRS SBBYS (Say-Barber/Biesecker/Young-Simpson) type, with distinctive dysmorphic features and inconstant anomalies including heart defect, optic atrophy, deafness, hypoplastic teeth, cleft palate, joint limitations, and hypothyroidism. BMRS type SBBYS is probably an etiologically heterogeneous phenotype, as AD and apparently AR forms exist; (4) BMRS, MKB (Maat-Kievit-Brunner) type, with coarse, triangular face, which is probably sex-linked; (5) BMRS V (Verloes) type, a probable new type with severe microcephaly, hypsarrhythmia, adducted thumbs, cleft palate, and abnormal genitalia, which is likely autosomal recessive. Types MKB and V are newly described here. Copyright 2006 Wiley-Liss, Inc.

    Low plasma 25-hydroxy-vitamin D (25OHD) is associated with polycystic ovary syndrome (PCOS). Vitamin D deficiency may contribute to the development of insulin resistance, visceral fat and low level of adiponectin which are common feature in PCOS women. This study aimed to evaluate the effect of vitamin D supplementation on insulin resistance, visceral fat, and adiponectin in hypovitaminosis D women with polycystic ovary syndrome. In this randomized, placebo-controlled clinical trial, 44 PCOS women aged 20-38 years with plasma 25OHD D3 once weekly in the intervention group or placebo. The visceral adipose tissue, Insulin resistance (HOMA-IR), HOMA-B, QUICKI, and circulating adiponectin were compared before and after the intervention within groups using paired tests and the mean changes were analyzed between two groups by independent t-test. Of 44 eligible participates, 36 patients (81.8%) completed the study. After 8 week intervention, vitamin D supplementation compared to the placebo group significantly decreased fasting plasma glucose (FPG) (7.67 ± 7.66 versus 1.71 ± 7.50 mg/dL, p = .001) and significantly increased homeostasis model of assessment-estimated B cell function (HOMA-B) (129.76 ± 121.02 versus 48.32 ± 128.35, p = .014), Adiponectin (5.17 ± 8.09 versus -5.29 ± 8.64 mg/dL, p = .001), and serum vitamin D level (28.24 ± 6.47 versus 3.55 ± 4.25 ng/mL, p = .001). Vitamin D supplementation in vitamin D deficient women with PCOS, improved the FPG, HOMA-B, Adiponectin, and serum vitamin D level.

    Tongue inspection is a unique and important method of diagnosis in traditional Chinese medicine (TCM). It is a diagnostic approach which involves observing the changes in the tongue proper and tongue coating in order to understand the physiological functions and pathological changes of the body. However, the biological basis of TCM tongue diagnosis remains to be poorly understood and lacks systematic investigation at the molecular level. In this study, we evaluated the effects of tongue coating microbiome on changes in the tongue texture and coating in patients with post-menopausal osteoporosis (PMO) of Gan‑shen deficiency syndrome type. Our aim was to delineate the mechanisms of tongue coating microbiome-induced changes in the tongue texture and coating by investigating the histomorphological changes and performing a bacterial analysis of the tongue coating. We found that the number of intermediate cells in the red tongue with a thin coating was higher, while the number of superficial cells in the red tongue with a thin coating was lower. The maturation value (MV) of tongue exfoliated cells in the red tongue with a thin coating decreased, compared with that in the pale red tongue with a thin white coating. Furthermore, the total bacterial count, oral streptococcus, Gram‑positive (G+) and Gram‑negative (G-) anaerobic bacteria in the red tongue with a thin coating was significantly decreased compared with the pale red tongue with a thin white coating. The results of ultrastructural examination demonstrated that the number of epithelial cells and bacteria in the red tongue with a thin coating decreased compared with that in the pale red tongue with a thin white coating. These observations indicate that the tongue coating microbiome may be an important factor contributing to changes in the tongue in patients with PMO of Gan‑shen deficiency syndrome type.

    Rothmund-Thomson syndrome (RTS) is a heterogeneous disease, associated with increased prevalence of osteosarcoma in very young patients with a mutated RECQL4 gene. In this study, we tested the ability of RECQL4 deficient fibroblasts, derived from a RTS patient to recover from hydrogen peroxide (H 2 O 2 )-induced oxidative stress/damage. Immunoperoxidase staining for 8-oxo-deoxyguanosine (8-oxo-dG) formation in RTS and normal human fibroblasts were compared to assess DNA damage. We determined DNA synthesis, cell growth, cell cycle distribution, and viability in RTS and normal human fibroblasts before and after H 2 O 2 treatment. H 2 O 2 induces 8-oxo-dG formation in both RTS and normal fibroblasts. In normal human fibroblasts, RECQL4 was predominantly localized to cytoplasm; nuclear translocation and foci formation occurred in response to oxidant stimulation. After recovery from oxidant exposure, viable RTS fibroblasts showed irreversible growth arrest compared to normal fibroblasts. DNA synthesis decreased significantly in treated RTS cells, with concomitant reduction of cells in the S-phase. These results suggest that enhanced oxidant sensitivity in RECQL4 deficient fibroblasts derived from RTS patients could be attributed to abnormal DNA metabolism and proliferation failure. The ramifications of these findings on osteosarcoma prevalence and heterogeneity in RTS are discussed

    Patients with severe Wernicke-Korsakoff syndrome (WKS) associated with vitamin B1 (thiamine) deficiency (TD) show enduring impairment of memory formation. The mechanisms of memory impairment induced by TD remain unknown. Here, we show that hippocampal degeneration is a potential microendophenotype (an endophenotype of brain disease at the cellular and synaptic levels) of WKS in pyrithiamine-induced thiamine deficiency (PTD) mice, a rodent model of WKS. PTD mice show deficits in the hippocampus-dependent memory formation, although they show normal hippocampus-independent memory. Similarly with WKS, impairments in memory formation did not recover even at 6 months after treatment with PTD. Importantly, PTD mice exhibit a decrease in neurons in the CA1, CA3, and dentate gyrus (DG) regions of the hippocampus and reduced density of wide dendritic spines in the DG. Our findings suggest that TD induces hippocampal degeneration, including the loss of neurons and spines, thereby leading to enduring impairment of hippocampus-dependent memory formation.

    Autosomal dominant deficiency of signal transducer and activator of transcription 3 (STAT3) is the main genetic etiology of hyper-immunoglobulin (Ig) E syndrome. We documented the molecular, cellular, and clinical features of 60 patients with heterozygous STAT3 mutations from 47 kindreds followed in France. We identified 11 known and 13 new mutations of STAT3. Low levels of interleukin (IL)-6-dependent phosphorylation and nuclear translocation (or accumulation) of STAT3 were observed in Epstein-Barr virus-transformed B lymphocytes (EBV-B cells) from all STAT3-deficient patients tested. The immunologic phenotype was characterized by high serum IgE levels (96% of the patients), memory B-cell lymphopenia (94.5%), and hypereosinophilia (80%). A low proportion of IL-17A-producing circulating T cells was found in 14 of the 15 patients tested. Mucocutaneous infections were the most frequent, typically caused by Staphylococcus aureus (all patients) and Candida albicans (85%). Up to 90% of the patients had pneumonia, mostly caused by Staph. aureus (31%) or Streptococcus pneumoniae (30%). Recurrent pneumonia was associated with secondary bronchiectasis and pneumatocele (67%), as well as secondary aspergillosis (22%). Up to 92% of the patients had dermatitis and connective tissue abnormalities, with facial dysmorphism (95%), retention of decidual teeth (65%), osteopenia (50%), and hyperextensibility (50%). Four patients developed non-Hodgkin lymphoma. The clinical outcome was favorable, with 56 patients, including 43 adults, still alive at the end of study (mean age, 21 yr; range, 1 mo to 46 yr). Only 4 patients died, 3 from severe bacterial infection (aged 1, 15, and 29 yr, respectively). Antibiotic prophylaxis (90% of patients), antifungal prophylaxis (50%), and IgG infusions (53%) improved patient health, as demonstrated by the large decrease in pneumonia recurrence. Overall, the prognosis of STAT3 deficiency may be considered good, provided that multiple prophylactic

    Although deficiency of complex I of the mitochondrial respiratory chain is a frequent cause of encephalopathy in children, only a few mutations have been reported in each of its subunits. In the absence of families large enough for conclusive segregation analysis and of robust functional testing, it is difficult to unequivocally show the causality of the observed mutations and to delineate genotype-phenotype correlations, making additional observations necessary. We observed two consanguineous siblings with an early-onset encephalopathy, medulla, brainstem and mesencephalon lesions on brain magnetic resonance imaging and death before 8 months of age, caused by a complex I deficiency. We used a homozygosity mapping approach and identified a missense mutation in the NDUFV1 gene. The mutation, p.Arg386His, affects a highly conserved residue, contiguous to a cysteine residue known to coordinate an Fe ion. This observation adds to our understanding of complex I deficiency disease. It validates the important role of Arg386 and therefore supports the current molecular model of iron-sulfur clusters in NDUFV1. © 2011 John Wiley & Sons A/S.

    Smith-Magenis syndrome (SMS) is a neurodevelopmental disorder associated with intellectual disability, sleep disturbances, early onset obesity and vast behavioral deficits. We used the Behavior Problems Inventory-01 to categorize the frequency and severity of behavioral abnormalities in a SMS cohort relative to individuals with intellectual disability of heterogeneous etiology. Self-injurious, stereotyped, and aggressive/destructive behavioral scores indicated that both frequency and severity were significantly higher among individuals with SMS relative to those with intellectual disability. Next, we categorized food behaviors in our SMS cohort across age using the Food Related Problems Questionnaire (FRPQ) and found that problems began to occur in SMS children as early as 5-11 years old, but children 12-18 years old and adults manifested the most severe problems. Furthermore, we evaluated the similarities of SMS adult food-related behaviors to those with intellectual disability and found that SMS adults had more severe behavioral problems. Many neurodevelopmental disorders exhibit syndromic obesity including SMS. Prader-Willi syndrome (PWS) is the most frequent neurodevelopmental disorder with syndromic obesity and has a well-established management and treatment plan. Using the FRPQ we found that SMS adults had similar scores relative to PWS adults. Both syndromes manifest weight gain early in development, and the FRPQ scores highlight specific areas in which behavioral similarities exist, including preoccupation with food, impaired satiety, and negative behavioral responses. SMS food-related behavior treatment paradigms are not as refined as PWS, suggesting that current PWS treatments for prevention of obesity may be beneficial for individuals with SMS.

    Full Text Available Kidney Yang Deficiency Syndrome (KDS-Yang, a typical condition in Chinese medicine, shares similar clinical signs of the glucocorticoid withdrawal syndrome. To date, the underlying mechanism of KDS-Yang has been remained unclear, especially at the metabolic level. In this study, we report a metabolomic profiling study on a classical model of KDS-Yang in rats induced by hydrocortisone injection to characterize the metabolic transformation using gas chromatography/time-of-flight mass spectrometry. WKY1, a polysaccharide extract from Astragalus membranaceus and Lycium barbarum, and WKY2, an aqueous extract from a similar formula containing Astragalus membranaceus, Lycium barbarum, Morinda officinalis, Taraxacum mongolicum, and Cinnamomum cassia presl, were used separately for protective treatments of KDS-Yang. The changes of serum metabolic profiles indicated that significant alterations of key metabolic pathways in response to abrupt hydrocortisone perturbation, including decreased energy metabolism (lactic acid, acetylcarnitine, lipid metabolism (free fatty acids, 1-monolinoleoylglycerol, and cholesterol, gut microbiota metabolism (indole-3-propionic acid, biosynthesis of catecholamine (norepinephrine, and elevated alanine metabolism, were attenuated or normalized with different degrees by the pretreatment of WKY1 or WKY2, which is consistent with the observations in which the two herbal agents could ameliorate biochemical markers of serum cortisone, adrenocorticotropic (ACTH, and urine 17-hydroxycorticosteroids (17-OHCS.

    KCNH2 encodes the Kv11.1 α-subunit that underlies the rapidly activating delayed-rectifier K + current in the heart. Loss-of-function KCNH2 mutations cause long QT syndrome type 2 (LQT2), and most LQT2-linked missense mutations inhibit the trafficking of Kv11.1 channel protein to the cell surface membrane. Several trafficking-deficient LQT2 mutations (e.g., G601S) generate Kv11.1 proteins that are sequestered in a microtubule-dependent quality control (QC) compartment in the transitional endoplasmic reticulum (ER). We tested the hypothesis that the QC mechanisms that regulate LQT2-linked Kv11.1 protein trafficking are mutation-specific. Confocal imaging analyses of HEK293 cells stably expressing the trafficking-deficient LQT2 mutation F805C showed that, unlike G601S-Kv11.1 protein, F805C-Kv11.1 protein was concentrated in several transitional ER subcompartments. The microtubule depolymerizing drug nocodazole differentially affected G601S- and F805C-Kv11.1 protein immunostaining. Nocodazole caused G601S-Kv11.1 protein to distribute into peripheral reticular structures, and it increased the diffuse immunostaining of F805C-Kv11.1 protein around the transitional ER subcompartments. Proteasome inhibition also affected the immunostaining of G601S- and F805C-Kv11.1 protein differently. Incubating cells in MG132 minimally impacted G601S-Kv11.1 immunostaining, but it dramatically increased the diffuse immunostaining of F805C-Kv11.1 protein in the transitional ER. Similar results were seen after incubating cells in the proteasome inhibitor lactacystin. Differences in the cellular distribution of G601S-Kv11.1 and F805C-Kv11.1 protein persisted in transfected human inducible pluripotent stem cell derived cardiomyocytes. These are the first data to visually demonstrate mutation-specific differences in the trafficking-deficient LQT2 phenotype, and this study has identified a novel way to categorize trafficking-deficient LQT2 mutations based on differences in intracellular

    Wolf-Hirschhorn syndrome (WHS) is a rare congenital disorder occurring in approximately 1/50 000 births, with marked pre- and postnatal growth failure. WHS results from the hemizygous deletion encompassing the 4p16.3 region. This report of two children with WHS shows that growth hormone treatment in selected children with WHS and severe short stature may have a substantial effect on long-term growth.

    Acute axonal polyneuropathy and Wernicke-Korsakoff encephalopathy developed simultaneously in three patients. Nerve conduction studies (NCS) detected markedly decreased compound muscle action potentials (CMAPs) and sensory nerve action potentials (SNAPs) with minimal conduction slowing; sympathetic skin responses (SSRs) were also notably decreased. Sural nerve biopsies showed only mild axonal degeneration with scattered myelin ovoid formation. The symptoms of neuropathy lessened within two weeks after an intravenous thiamine infusion. CMAPs, SNAPs, and SSRs also increased considerably. We suggest that this is a new type of peripheral nerve impairment: physiological conduction failure with minimal conduction delay due to thiamine deficiency.

    Prader-Willi syndrome (PWS) is a neurogenetic disorder characterized by muscular hypotonia, psychomotor delay, feeding difficulties and failure to thrive in infancy. GH treatment improves growth velocity and body composition. Research on the effects of GH on psychomotor development in infants with PWS is limited. To evaluate psychomotor development in PWS infants and toddlers during GH treatment compared to randomized controls. Forty-three PWS infants were evaluated at baseline. Twenty-nine of them were randomized into a GH group (n = 15) receiving 1 mg/m(2)/day GH or a non-GH-treated control group (n = 14). At baseline and after 12 months of follow-up, analysis with Bayley Scales of Infant Development II (BSID-II) was performed. Data were converted to percentage of expected development for age (%ed), and changes during follow-up were calculated. Infants in the GH group had a median age of 2.3 years [interquartile range (IQR) 1.7-3.0] and in the control group of 1.5 years (IQR 1.2-2.7) (P = 0.17). Both mental and motor development improved significantly during the first year of study in the GH group vs. the control group: median (IQR) change was +9.3% (-5.3 to 13.3) vs.-2.9% (-8.1 to 4.9) (P development and +11.2% (-4.9 to 22.5) vs.-18.5% (-27.9 to 1.8) (P development, respectively. One year of GH treatment significantly improved mental and motor development in PWS infants compared to randomized controls.

    This study examined the effects of optimism and gratitude on self-reported health behavior adherence, physical functioning and emotional well-being after an acute coronary syndrome (ACS). Among 156 patients, we examined associations between optimism and gratitude measured 2 weeks post-ACS and 6-month outcomes: adherence to medical recommendations, mental and physical health-related quality of life (HRQoL), physical functioning, depressive symptoms and anxiety. Multivariable linear regression models were used, controlling for increasing levels of adjustment. Optimism [β=.11, standard error (S.E.)=.05, P=.038] and gratitude (β=.10, S.E.=.05, P=.027) at 2 weeks were associated with subsequent self-reported adherence to medical recommendations (diet, exercise, medication adherence, stress reduction) at 6 months in fully adjusted models. Two-week optimism and gratitude were associated with improvements in mental HRQoL (optimism: β=.44, S.E.=.13, P=.001; gratitude: β=.33, S.E.=.12, P=.005) and reductions in symptoms of depression (optimism: β=-.11, S.E.=.05, P=.039; gratitude: β=-.10, S.E.=.05, P=.028) and anxiety (optimism: β=-.15, S.E.=.05, P=.004; gratitude: β=-.10, S.E.=.05, P=.034) at 6 months. Optimism and gratitude at 2 weeks post-ACS were associated with higher self-reported adherence and improved emotional well-being 6 months later, independent of negative emotional states. Optimism and gratitude may help recovery from an ACS. Interventions promoting these positive constructs could help improve adherence and well-being. Copyright © 2016 Elsevier Inc.

    In a 14-year-old boy with polyposis and rectosigmoid carcinoma, we identified a novel POLE germline mutation, p.(Val411Leu), previously found as recurrent somatic mutation in 'ultramutated' sporadic cancers. This is the youngest reported cancer patient with polymerase proofreading-associated polyposis indicating that POLE mutation p.(Val411Leu) may confer a more severe phenotype than previously reported POLE and POLD1 germline mutations. The patient had multiple café-au-lait macules and a pilomatricoma mimicking the clinical phenotype of constitutional mismatch repair deficiency. We hypothesize that these skin features may be common to different types of constitutional DNA repair defects associated with polyposis and early-onset cancer.

    Targeted disruption of the murine p27(Kip1) gene caused a gene dose-dependent increase in animal size without other gross morphologic abnormalities. All tissues were enlarged and contained more cells, although endocrine abnormalities were not evident. Thymic hyperplasia was associated with increased T lymphocyte proliferation, and T cells showed enhanced IL-2 responsiveness in vitro. Thus, p27 deficiency may cause a cell-autonomous defect resulting in enhanced proliferation in response to mitogens. In the spleen, the absence of p27 selectively enhanced proliferation of hematopoietic progenitor cells. p27 deletion, like deletion of the Rb gene, uniquely caused neoplastic growth of the pituitary pars intermedia, suggesting that p27 and Rb function in the same regulatory pathway. The absence of p27 also caused an ovulatory defect and female sterility. Maturation of secondary ovarian follicles into corpora lutea, which express high levels of p27, was markedly impaired.

    Lamin is an intermediate protein underlying the nuclear envelope and it plays a key role in maintaining the integrity of the nucleus. A defect in the processing of its precursor by a metalloprotease, ZMPSTE24, results in the accumulation of farnesylated prelamin in the nucleus and causes various diseases, including Hutchinson-Gilford progeria syndrome (HGPS). However, the role of lamin processing is unclear in fish species. Here, we generated zmpste24-deficient medaka and evaluated their phenotype. Unlike humans and mice, homozygous mutants did not show growth defects or lifespan shortening, despite lamin precursor accumulation. Gonadosomatic indices, blood glucose levels, and regenerative capacity of fins were similar in 1-year-old mutants and their wild-type (WT) siblings. Histological examination showed that the muscles, subcutaneous fat tissues, and gonads were normal in the mutants at the age of 1 year. However, the mutants showed hypersensitivity to X-ray irradiation, although p53target genes, p21 and mdm2, were induced 6 h after irradiation. Immunostaining of primary cultured cells from caudal fins and visualization of nuclei using H2B-GFP fusion proteins revealed an abnormal nuclear shape in the mutants both in vitro and in vivo. The telomere lengths were significantly shorter in the mutants compared to WT. Taken together, these results suggest that zmpste24-deficient medaka phenocopied HGPS only partially and that abnormal nuclear morphology and lifespan shortening are two independent events in vertebrates.

    Primary insulin-like growth factor-I (IGF-I) deficiencies, such as in Laron syndrome (LS), are a unique model in man to study the consequences resulting from defects in growth hormone (GH) signal transmission. To assess retrospectively the effect of IGF-I deficiency and its therapy on the various cells of the hematopoietic system as reflected by peripheral blood counts. Two groups of patients were studied. The first group consisted of 11 untreated patients with LS, seven males and four females, who were followed from childhood into adult age. Average age at the time of data analysis was 45.4 +/- 9.6 years. The second group included ten children with LS, six males and four females, who received IGF-I replacement therapy for an average period of 6 years, ranging in age from 0.9-11 years. The mean age at initiation of therapy was 6.9 +/- 4.28 years. Only the seven children treated for 5 years or more were included in the analysis. Data on blood counts were collected from the patients' charts. Blood samples were drawn at baseline, weekly during the first month, once a month during the first year, and once every 3 months thereafter. Statistical analysis of the change over time was performed using repeated measures ANOVA. Children with LS had red cell indices in the lower normal range and an elevated monocyte count. A statistically significant rise in red blood cell (RBC) indices was seen in children during IGF-I therapy: RBC rose from 4.66 x 10(6)/ml to 4.93 x 10(6)/ml (p = 0.011); hemoglobin from 11.55 g/dl to 13.01 g/dl (p syndrome, confirms that IGF-I has a strong stimulatory effect on erythropoiesis. In addition, IGF-I therapy had a reducing effect on monocytes and platelets, an effect not previously described. The mechanism by which IGF-I mediates these effects needs further elucidation.

  1. Mental traveling along psychological distances: The effects of cultural syndromes, perspective flexibility, and construal level.

    Science.gov (United States)

    Wong, Vincent Chi; Wyer, Robert S

    2016-07-01

    Individuals' psychological distance from the stimuli they encounter in daily life can influence the abstractness or generality of the mental representations they form of these stimuli. However, these representations can also depend on the perspective from which the stimuli are construed. When individuals have either an individualistic social orientation or a short-term temporal orientation, they construe psychologically distal events more globally than they construe proximal ones, as implied by construal level theory (Trope & Liberman, 2010). When they have either a collectivistic social orientation or a long-term temporal orientation, however, they not only construe the implications of distal events more concretely than individuals with an egocentric perspective but also construe the implications of proximal events in more abstract terms. These effects are mediated by the flexibility of the perspectives that people take when they make judgments. Differences in perspective flexibility account for the impact of both situationally induced differences in social and temporal orientation and more chronic cultural differences in these orientations.

    Full Text Available A nova concepção e terminologia adotada pela língua inglesa no contexto da ainda designada "deficiência mental" parece ter alcançado um consenso estável e satisfatório face às expectativas que a sociedade deve esperar das populações com esse diagnóstico, enfatizando agora o impacto que as exigências do envolvimento detém no desenvolvimento individual, reforçando-se, assim, a necessidade emergente da alteração de mentalidades e atitudes para com estas populações. Para este efeito, o presente artigo introduz uma nova proposta de alteração da terminologia em português de deficiência mental/intelectual para "dificuldade intelectual e desenvolvimental", explicitando e fundamentando as razões para a mesma.The new conception and terminology of "intellectual disability" adopted in the English language referring to what was known earlier as "mental retardation" seems to have achieved a satisfactory and stable consensus regarding society expectations for those groups to which this diagnosis refers. Currently, the focus is on the environmental impact on human functioning and development, which will reinforce the emergent need for altering attitudes towards such groups. To this end, this article defends a new proposal changing the Portuguese term from mental retardation to intellectual and developmental disability, establishing the term's meaning and boundaries.

    Full Text Available In humans, congenital and hereditary skin diseases associated with epidermal cell-cell separation (acantholysis are very rare, and spontaneous animal models of these diseases are exceptional. Our objectives are to report a novel congenital acantholytic dermatosis that developed in Chesapeake Bay retriever dogs. Nine affected puppies in four different litters were born to eight closely related clinically normal dogs. The disease transmission was consistent with an autosomal recessive mode of inheritance. Clinical signs occurred immediately after birth with superficial epidermal layers sloughing upon pressure. At three month of age, dogs exhibited recurrent superficial skin sloughing and erosions at areas of friction and mucocutaneous junctions; their coat was also finer than normal and there were patches of partial hair loss. At birth, histopathology revealed severe suprabasal acantholysis, which became less severe with ageing. Electron microscopy demonstrated a reduced number of partially formed desmosomes with detached and aggregated keratin intermediate filaments. Immunostaining for desmosomal adhesion molecules revealed a complete lack of staining for plakophilin-1 and anomalies in the distribution of desmoplakin and keratins 10 and 14. Sequencing revealed a homozygous splice donor site mutation within the first intron of PKP1 resulting in a premature stop codon, thereby explaining the inability to detect plakophilin-1 in the skin. Altogether, the clinical and pathological findings, along with the PKP1 mutation, were consistent with the diagnosis of ectodermal dysplasia-skin fragility syndrome with plakophilin-1 deficiency. This is the first occurrence of ectodermal dysplasia-skin fragility syndrome in an animal species. Controlled mating of carrier dogs would yield puppies that could, in theory, be tested for gene therapy of this rare but severe skin disease of children.

    Work from our laboratory in both in-patient and outpatient facilities utilizing the Comprehensive Analysis of Reported Drugs (CARD)™ found a significant lack of compliance to prescribed treatment medications and a lack of abstinence from drugs of abuse during active recovery. This unpublished, ongoing research provides an impetus to develop accurate genetic diagnosis and holistic approaches that will safely activate brain reward circuitry in the mesolimbic dopamine system. This editorial focuses on the neurogenetics of brain reward systems with particular reference to genes related to dopaminergic function. The terminology “Reward Deficiency Syndrome” (RDS), used to describe behaviors found to have an association with gene-based hypodopaminergic function, is a useful concept to help expand our understanding of Substance Use Disorder (SUD), process addictions, and other obsessive, compulsive and impulsive behaviors. This editorial covers the neurological basis of pleasure and the role of natural and unnatural reward in motivating and reinforcing behaviors. Additionally, it briefly describes the concept of natural dopamine D2 receptor agonist therapy coupled with genetic testing of a panel of reward genes, the Genetic Addiction Risk Score (GARS). It serves as a spring-board for this combination of novel approaches to the prevention and treatment of RDS that was developed from fundamental genomic research. We encourage further required studies. PMID:23264886

    Full Text Available Background: Adolescents knowledge with their safe practices pertaining to human immunodeficiency virus (HIV has a critical impact on the prevention of contracting and spreading HIV. Reports have shown that adolescents in the general setting engage in activities that enhance the spread of the virus. Aim: The study assessed school adolescent's HIV/acquired immune deficiency syndrome (AIDS knowledge, with its impact on their behaviors and attitudes regarding the infection. Materials and Methods: Two hundred randomly selected adolescent students from 10 different schools in the city metropolis were involved in the cross-sectional study. Primary data were collected using a validated self-administered questionnaire on students HIV/AIDS knowledge, attitude toward people living with HIV/AIDS (PLWHA, and safe practices preventing the spread of HIV/AIDS. Results: The study observed that majority of the students had good knowledge about HIV/AIDS, had good attitude toward PLWHA, and engaged in safe practices that prevent the spread of HIV. The sources of HIV/AIDS information were hospital, school, home, electronic, and print media. The study also found that HIV/AIDS knowledge instilled good attitudes and behavioral practices in the students. Conclusion: The study shows that school sex education, as well as health promotion campaigns through media platforms, could impact positively on the knowledge, attitude, and behavioral practices of adolescents in curbing the spread of HIV/AIDS.

    Data on the clinical presentation of constitutional mismatch repair deficiency syndrome (CMMRD) is accumulating. However, as the extraintestinal manifestations are often fatal and occur at early age, data on the systematic evaluation of the gastrointestinal tract is scarce. Here we describe 11 subjects with verified biallelic carriage and who underwent colonoscopy, upper endoscopy and small bowel evaluation. Five subjects were symptomatic and in six subjects the findings were screen detected. Two subjects had colorectal cancer and few adenomatous polyps (19, 20 years), three subjects had polyposis-like phenotype (13, 14, 16 years), four subjects had few adenomatous polyps (8, 12-14 years) and two subjects had no polyps (both at age 6). Of the three subjects in the polyposis-like group, two subjects had already developed high-grade dysplasia or cancer and one subject had atypical juvenile polyps suggesting juvenile polyposis. Three out of the five subjects that underwent repeated exams had significant findings during short interval. The gastrointestinal manifestations of CMMRD are highly dependent upon age of examination and highly variable. The polyps may also resemble juvenile polyposis. Intensive surveillance according to current guidelines is mandatory. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Histoplasmosis is one of the most common and deadly opportunistic infections among persons living with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome in Latin America, but due to limited diagnostic capacity in this region, few data on the burden and clinical characteristics of this disease exist. Between 2005 and 2009, we enrolled patients ≥ 18 years of age with suspected histoplasmosis at a hospital-based HIV clinic in Guatemala City. A case of suspected histoplasmosis was defined as a person presenting with at least three of five clinical or radiologic criteria. A confirmed case of histoplasmosis was defined as a person with a positive culture or urine antigen test for Histoplasma capsulatum . Demographic and clinical data were also collected and analyzed. Of 263 enrolled as suspected cases of histoplasmosis, 101 (38.4%) were confirmed cases. Median time to diagnosis was 15 days after presentation (interquartile range [IQR] = 5-23). Crude overall mortality was 43.6%; median survival time was 19 days (IQR = 4-69). Mycobacterial infection was diagnosed in 70 (26.6%) cases; 26 (25.7%) histoplasmosis cases were coinfected with mycobacteria. High mortality and short survival time after initial symptoms were observed in patients with histoplasmosis. Mycobacterial coinfection diagnoses were frequent, highlighting the importance of pursuing diagnoses for both diseases.

    To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

    Dopamine along with other chemical messengers like serotonin, cannabinoids, endorphins and glutamine, play significant roles in brain reward processing. There is a devastating opiate/opioid epidemicin the United States. According to the Centers for Disease Control and Prevention (CDC), at least 127 people, young and old, are dying every day due to narcotic overdose and alarmingly heroin overdose is on the rise. The Food and Drug Administration (FDA) has approved some Medication-Assisted Treatments (MATs) for alcoholism, opiate and nicotine dependence, but nothing for psychostimulant and cannabis abuse. While these pharmaceuticals are essential for the short-term induction of “psychological extinction,” in the long-term caution is necessary because their use favors blocking dopaminergic function indispensable for achieving normal satisfaction in life. The two institutions devoted to alcoholism and drug dependence (NIAAA & NIDA) realize that MATs are not optimal and continue to seek better treatment options. We review, herein, the history of the development of a glutaminergic-dopaminergic optimization complex called KB220 to provide for the possible eventual balancing of the brain reward system and the induction of “dopamine homeostasis.” This complex may provide substantial clinical benefit to the victims of Reward Deficiency Syndrome (RDS) and assist in recovery from iatrogenically induced addiction to unwanted opiates/opioids and other addictive behaviors.

    Full Text Available Background: Illness uncertainty is a source of a chronic and pervasive psychological stress for people living with human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS (PLWH, and largely affects their quality of life and the ability to cope with the disease. Based on the uncertainty in illness theory, the social support is one of the illness uncertainty antecedents, and influences the level of uncertainty perceived by patients. Aim: To examine uncertainty in PLWH and its correlation with social support in Iran. Materials and Methods: This cross-sectional correlational study was conducted with 80 PLWH presenting to AIDS Research Center, Tehran, Iran in 2013. The data collected using illness uncertainty and social support inventories were analyzed through Pearson′s correlation coefficient, Spearman′s correlation coefficient, and regression analysis. Results: The results showed a high level of illness uncertainty in PLWH and a negative significant correlation between perceived social support and illness uncertainty ( P = 0.01, r = -0.29. Conclusion: Uncertainty is a serious aspect of illness experience in Iranian PLWH. Providing adequate, structured information to patients as well as opportunities to discuss their concerns with other PLWH and receive emotional support from their health care providers may be worthwhile.

    The classical ketogenic diet (KD) is a high-fat, very low-carbohydrate normocaloric diet used for drug-resistant epilepsy and Glucose Transporter 1 Deficiency Syndrome (GLUT1 DS). In animal models, high fat diet induces large alterations in microbiota producing deleterious effects on gut health. We carried out a pilot study on patients treated with KD comparing their microbiota composition before and after three months on the diet. Six patients affected by GLUT1 DS were asked to collect fecal samples before and after three months on the diet. RT - PCR analysis was performed in order to quantify Firmicutes, Bacteroidetes, Bifidobacterium spp., Lactobacillus spp., Clostridium perfringens, Enterobacteriaceae, Clostridium cluster XIV, Desulfovibrio spp. and Faecalibacterium prausnitzii. Compared with baseline, there were no statistically significant differences at 3 months in Firmicutes and Bacteroidetes. However fecal microbial profiles revealed a statistically significant increase in Desulfovibrio spp. (p = 0.025), a bacterial group supposed to be involved in the exacerbation of the inflammatory condition of the gut mucosa associated to the consumption of fats of animal origin. A future prospective study on the changes in gut microbiota of all children with epilepsy started on a KD is warranted. In patients with dysbiosis demonstrated by fecal samples, it my be reasonable to consider an empiric trial of pre or probiotics to potentially restore the «ecological balance» of intestinal microbiota.

    Twenty patients with the acquired immune deficiency syndrome (AIDS) and suspected Pneumocystis carinii pneumonia were evaluated by 67 Ga scintigraphy and fiberoptic bronchoscopy for initial diagnosis and response to therapy. Lung uptake of 67 Ga was demonstrated in 100% of AIDS patients with P. carinii pneumonia, including those with subclinical infection. Fiberoptic bronchoscopy identified P. carinii in the bronchial washings of 100% of cases (19 patients), whereas only 13 of 16 (81%) patients had P. carinii in lung tissue obtained by transbronchial biopsy. Repeat fiberoptic bronchoscopy was performed in 16 of 20 patients. After 2 to 4 wk of therapy, P. carinii was identified in bronchial washings in 8 of 16 (50%) patients and in transbronchial biopsy in 1 of 10 (10%) patients examined. Bronchial washing has a higher yield than transbronchial biopsy in demonstrating P. carinii in patients with AIDS and may evolve as the procedure of choice in such patients. Based on the clinical course and results of 67 Ga scintigraphy and fiberoptic bronchoscopy in AIDS patients with P. carinii pneumonia, optimal therapy may require at least 3 wk of treatment

    Now after many years of successful bariatric (weight-loss) surgeries directed at the obesity epidemic clinicians are reporting that some patients are replacing compulsive overeating with newly acquired compulsive disorders such as alcoholism, gambling, drugs, and other addictions like compulsive shopping and exercise. This review article explores evidence from psychiatric genetic animal and human studies that link compulsive overeating and other compulsive disorders to explain the phenomenon of addiction transfer. Possibly due to neurochemical similarities, overeating and obesity may act as protective factors reducing drug reward and addictive behaviors. In animal models of addiction withdrawal from sugar induces imbalances in the neurotransmitters, acetylcholine and dopamine, similar to opiate withdrawal. Many human neuroimaging studies have supported the concept of linking food craving to drug craving behavior. Previously our laboratory coined the term Reward Deficiency Syndrome (RDS) for common genetic determinants in predicting addictive disorders and reported that the predictive value for future RDS behaviors in subjects carrying the DRD2 Taq A1 allele was 74%. While poly genes play a role in RDS, we have also inferred that disruptions in dopamine function may predispose certain individuals to addictive behaviors and obesity. It is now known that family history of alcoholism is a significant obesity risk factor. Therefore, we hypothesize here that RDS is the root cause of substituting food addiction for other dependencies and potentially explains this recently described Phenomenon (addiction transfer) common after bariatric surgery.

    Stroke-like episodes (SLE) occur in phosphomannomutase deficiency (PMM2-CDG), and may complicate the course of channelopathies related to Familial Hemiplegic Migraine (FHM) caused by mutations in CACNA1A (encoding CaV2.1 channel). The underlying pathomechanisms are unknown. We analyze clinical variables to detect risk factors for SLE in a series of 43 PMM2-CDG patients. We explore the hypothesis of abnormal CaV2.1 function due to aberrant N-glycosylation as a potential novel pathomechanism of SLE and ataxia in PMM2-CDG by using whole-cell patch-clamp, N-glycosylation blockade and mutagenesis. Nine SLE were identified. Neuroimages showed no signs of stroke. Comparison of characteristics between SLE positive versus negative patients’ group showed no differences. Acute and chronic phenotypes of patients with PMM2-CDG or CACNA1A channelopathies show similarities. Hypoglycosylation of both CaV2.1 subunits (α1A and α2α) induced gain-of-function effects on channel gating that mirrored those reported for pathogenic CACNA1A mutations linked to FHM and ataxia. Unoccupied N-glycosylation site N283 at α1A contributes to a gain-of-function by lessening CaV2.1 inactivation. Hypoglycosylation of the α2δ subunit also participates in the gain-of-function effect by promoting voltage-dependent opening of the CaV2.1 channel. CaV2.1 hypoglycosylation may cause ataxia and SLEs in PMM2-CDG patients. Aberrant CaV2.1 N-glycosylation as a novel pathomechanism in PMM2-CDG opens new therapeutic possibilities. PMID:29470411

    Chemokine receptor interactions coordinate leukocyte migration in inflammation. Chemokine receptors are GPCRs that when activated, are phosphorylated by GRKs to turn off G protein-mediated signaling yet recruit additional signaling machinery. Recently, GRK3 was identified as a negative regulator of CXCL12/CXCR4 signaling that is defective in human WHIM syndrome. Here, we report that GRK3−/− mice exhibit numerous features of human WHIM, such as impaired CXCL12-mediated desensitization, enhanced CXCR4 signaling to ERK activation, altered granulocyte migration, and a mild myelokathexis. Moreover, GRK3−/− protects mice from two acute models of inflammatory arthritis (K/BxN serum transfer and CAIA). In these granulocyte-dependent disease models, protection of GRK3−/− mice is mediated by retention of cells in the marrow, fewer circulating granulocytes in the peripheral blood, and reduced granulocytes in the joints during active inflammation. In contrast to WHIM, GRK3−/− mice have minimal hypogammaglobulinemia and a peripheral leukocytosis with increased lymphocytes and absent neutropenia. Thus, we conclude that the loss of GRK3-mediated regulation of CXCL12/CXCR4 signaling contributes to some, but not all, of the complete WHIM phenotype and that GRK3 inhibition may be beneficial in the treatment of inflammatory arthritis.

    Full Text Available Beta-actin, a critical player in cellular functions ranging from cell motility and the maintenance of cell shape to transcription regulation, was evaluated in the erythrocyte membranes from patients with typical Rett syndrome (RTT and methyl CpG binding protein 2 (MECP2 gene mutations. RTT, affecting almost exclusively females with an average frequency of 1∶10,000 female live births, is considered the second commonest cause of severe cognitive impairment in the female gender. Evaluation of beta-actin was carried out in a comparative cohort study on red blood cells (RBCs, drawn from healthy control subjects and RTT patients using mass spectrometry-based quantitative analysis. We observed a decreased expression of the beta-actin isoforms (relative fold changes for spots 1, 2 and 3: -1.82±0.15, -2.15±0.06, and -2.59±0.48, respectively in pathological RBCs. The results were validated by western blotting and immunofluorescence microscopy. In addition, beta-actin from RTT patients also showed a dramatic increase in oxidative posttranslational modifications (PTMs as the result of its binding with the lipid peroxidation product 4-hydroxy-2-nonenal (4-HNE. Our findings demonstrate, for the first time, a beta-actin down-regulation and oxidative PTMs for RBCs of RTT patients, thus indicating an altered cytoskeletal organization.

    Wolfram syndrome (WS) is a rare autosomal-recessive disorder that is caused by mutations in the WFS1 gene and is characterized by juvenile-onset diabetes, optic atrophy, hearing loss and a number of other complications. Here, we describe the creation and phenotype of Wfs1 mutant rats, in which exon 5 of the Wfs1 gene is deleted, resulting in a loss of 27 amino acids from the WFS1 protein sequence. These Wfs1-ex5-KO232 rats show progressive glucose intolerance, which culminates in the development of diabetes mellitus, glycosuria, hyperglycaemia and severe body weight loss by 12 months of age. Beta cell mass is reduced in older mutant rats, which is accompanied by decreased glucose-stimulated insulin secretion from 3 months of age. Medullary volume is decreased in older Wfs1-ex5-KO232 rats, with the largest decreases at the level of the inferior olive. Finally, older Wfs1-ex5-KO232 rats show retinal gliosis and optic nerve atrophy at 15 months of age. Electron microscopy revealed axonal degeneration and disorganization of the myelin in the optic nerves of older Wfs1-ex5-KO232 rats. The phenotype of Wfs1-ex5-KO232 rats indicates that they have the core symptoms of WS. Therefore, we present a novel rat model of WS.

    Schizophrenia has been linked with various medical comorbidities, particularly metabolic syndrome. The number of studies on this aspect is lacking in Malaysia. (1) Objective: To investigate metabolic syndrome rates and its associated factors. (2) Method: This is the first 10-year retrospective-outcome study of patients with first episode schizophrenia in Malaysia. Out of 394 patients diagnosed with first episode schizophrenia and registered with the National Mental Health Registry of Schizophrenia (NMHR) in the General Hospital Kuala Lumpur (GHKL) in 2004⁻2005, 174 patients consented to participate in the study. They were interviewed using a Schizophrenia outcome questionnaire and the International Physical Activity Questionnaire (IPAQ). The diagnosis of metabolic syndrome was made using the National Cholesterol Education Program—Third Adult Treatment Panel (NCEP ATP III). (3) Results: All patients’ weight, body mass index, fasting blood sugar, and blood pressure are significantly increased. Sixty-three subjects (36.2%) developed metabolic syndrome while 36 (23.2%) were hypertensive, and 41 (28.1%) were diabetic. Use of fluphenthixol depot (CI = 1.05⁻5.09, OR: 0.84, p = 0.039), reduced physical activity (CI = 0.13⁻1.00, OR: −1.04, p = 0.049), and substance use disorder (CI = 1.40, 13.89, OR: 1.48, p = 0.012) were significantly associated with metabolic syndrome based on univariate analysis. In further multivariate analysis, comorbid substance abuse was the only significant factor associated with metabolic syndrome after adjusting for physical activity and intramuscular depot. (4) Conclusion: Patients with schizophrenia are at high risk of metabolic syndrome. It is important to address substance use problems as an important risk factor of this comorbidity.

    Full Text Available Background: Irritable bowel syndrome (IBS is a functional gastrointestinal disorder with chronic abdominal pain, bowel habit variations, and lack of structural causes. Symptom intensity has a statistical relation with patients' quality of life (QOL and mental health. The first objective of the present study was to develop and provide a therapeutic plan based on cognitive behavioral therapy (CBT for IBS that was operated for the very first time in Iran. The second objective was to determine the effectiveness of these treatments on IBS symptoms intensity, health-related QOL, and psychological health among patients with IBS.Methods: The participants were 15 women with IBS. The participants were diagnosed on the basis of ROME-III diagnosis criteria. The data collection tools consisted of IBS Symptom Severity Scale (IBS-SSS, the Irritable Bowel Syndrome Quality of Life (IBS-QOL questionnaire, and the Symptom Checklist-90-Revised (SCL-90-R used to evaluate mental health. Data were collected during the weeks of 0, 4, 12, and 24, during the treatment process. The extracted data was examined statistically via repeated measures MANOVA in SPSS software.Results: CBT has a significant effect on IBS symptoms reduction, QOL improvement, and mental health promotion of the patients. The effect of the therapeutic plan persisted until the follow-up stage.Conclusion: According to the results, applied CBT can be specifically implemented as an effective treatment for IBS. Therefore, the use of this treatment is advised.

    Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a complex developmental disorder with serious medical, cognitive and emotional symptoms across the lifespan. This genetic deletion also imparts a lifetime risk for developing schizophrenia that is 25-30 times that of the general population. The origin of this risk is multifactorial and may include dysregulation of the stress response and immunological systems in relation to brain development. Vitamin D is involved in brain development and neuroprotection, gene transcription, immunological regulation and influences neuronal signal transduction. Low levels of vitamin D are associated with schizophrenia, depression and anxiety in the general population. Yet, little is known about how vitamin D levels in children with 22q11.2DS could mediate risk of psychosis in adulthood. Blood plasma levels of vitamin D were measured in children aged 7-16 years with (n=11) and without (n=16) 22q11.2DS in relation to parent reports of children's anxiety and atypicality. Anxiety and atypicality in childhood are risk indicators for the development of schizophrenia in those with 22q11.2DS and the general population. Children with 22q11.2DS had lower vitamin D levels, as well as elevated anxiety and atypicality compared with typical peers. Higher levels of anxiety, depression and internalizing problems but not atypicality were associated with lower levels of vitamin D. Vitamin D insufficiency may relate to higher levels of anxiety and depression, in turn contributing to the elevated risk of psychosis in this population. Further study is required to determine casual linkages between anxiety, stress, mood and vitamin D in children with 22q11.2DS.

    Full Text Available Polymorphisms in genes encoding folate metabolizing enzymes have been linked to an increased risk of maternal chromosomal nondisjunction in several populations. With the purpose of evaluating this relationship, we compared the frequencies of 677C>T and 1298A>C polymorphisms in the methylenetetrahydrofolate reductase gene (MTHFR and 66A>G in the methionine synthase reductase gene (MTRR between 103 young mothers of Down syndrome (DS individuals and 108 control mothers, whose offspring was karyotypically normal, correlating it with an estimative of folate and – related micronutrients levels intake. Maternal and paternal transmission frequencies of MTHFR 677T allele were also examined to access potential parent-of-origin effects. PCR-RFLP for genomic DNA was accomplished and allele/genotype frequencies differences were determined using the x2 test, whereas pattern of transmission of the MTHFR 677 allele was analyzed by transmission disequilibrium test. None of the polymorphisms seemed to be more frequent in case mothers than in controls, either individually or combined. The estimative of nutritional intake revealed that folate consumption median was inadequate in both groups, whereas methionine and zinc consumption medians were significantly greater in control mothers. It suggests that such interaction between genetic profile and environment could predispose this sub group of women to have a DS child. Additional studies focusing the interaction between nutritional intakes, biochemical data and folate pathway polymorphisms are needed to confirm the present results. The possibility of neutralize the biochemical negative effects of folate-related polymorphisms through oral supplementation could provide new targets for DS prevention.

    To investigate the correlation between insulin resistance (IR) and serum 25-OH-Vit D concentrations and hormonal parameters in lean women with polycystic ovary syndrome (PCOS). 50 lean women with PCOS and 40 body mass index (BMI) matched controls were compared in terms of fasting insulin and glucose, homeostatic model assessment insulin resistance (HOMA-IR), 25-OH-Vit D, high sensitivity C-reactive protein (hs-CRP), luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone, dehydroepiandrosterone sulfate (DHEA-S), total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides and Ferriman-Gallway (FG) scores. Correlation analyses were performed between HOMA-IR and metabolic and endocrine parameters. 30% of patients with PCOS demonstrated IR. Levels of 25-OH-Vit D, hsCRP, cholesterol, HDL, LDL, triglyceride and fasting glucose did not differ between the study and control groups. Fasting insulin, HOMA-IR, LH, total testosterone, and DHEA-S levels were higher in PCOS group. HOMA-IR was found to correlate with hs-CRP and total testosterone but not with 25-OH-Vit D levels in lean patients with PCOS. An association between 25-OH-Vit D levels and IR is not evident in lean women with PCOS. hs-CRP levels do not indicate to an increased risk of cardiovascular disease in this population of patients. Because a strong association between hyperinsulinemia and hyperandrogenism exists in lean women with PCOS, it is advisable for this population of patients to be screened for metabolic disturbances, especially in whom chronic anovulation and hyperandrogenism are observed together.

    Full Text Available Traditional Chinese medicine (TCM; 中醫 zhōng yī syndrome groups are based on the symptoms of human diseases and guide the use of Chinese herbs. The aim of this study was to examine the effects of TCM syndrome groups on biochemical characteristics and quality of life (QOL in women with metabolic syndrome (MS. Among the 1080 registered female patients screened at our outpatient clinic, a total of 322 women aged between 18 and 65 years and meeting the requirements of MS were enrolled. All the patients were asked to fill out a questionnaire on metabolic TCM syndrome groups and a questionnaire on the QOL, the Medical Outcomes Study (MOS Short Form-12 (SF-12. Data of biochemical characteristics were collected at the same time. The present study showed MS women in TCM syndrome groups had significantly lower physical and mental component scores in SF-12 compared with those not in TCM syndrome groups. We also found MS patients in TCM syndrome groups, except Kidney Deficiency syndrome, showed higher body mass indexes, waist circumference, and hip circumference. However, there was almost no difference in most biochemical characteristics between TCM syndrome groups. The MS patients diagnosed as belonging to TCM syndrome groups had poor QOL.

    Full Text Available Abstract Background Fumarate hydratase (HGNC approved gene symbol – FH, also known as fumarase, is an enzyme of the tricarboxylic acid (TCA cycle, involved in fundamental cellular energy production. First described by Zinn et al in 1986, deficiency of FH results in early onset, severe encephalopathy. In 2002, the Multiple Leiomyoma Consortium identified heterozygous germline mutations of FH in patients with multiple cutaneous and uterine leiomyomas, (MCUL: OMIM 150800. In some families renal cell cancer also forms a component of the complex and as such has been described as hereditary leiomyomatosis and renal cell cancer (HLRCC: OMIM 605839. The identification of FH as a tumor suppressor was an unexpected finding and following the identification of subunits of succinate dehydrogenase in 2000 and 2001, was only the second description of the involvement of an enzyme of intermediary metabolism in tumorigenesis. Description The FH mutation database is a part of the TCA cycle gene mutation database (formerly the succinate dehydrogenase gene mutation database and is based on the Leiden Open (source Variation Database (LOVD system. The variants included in the database were derived from the published literature and annotated to conform to current mutation nomenclature. The FH database applies HGVS nomenclature guidelines, and will assist researchers in applying these guidelines when directly submitting new sequence variants online. Since the first molecular characterization of an FH mutation by Bourgeron et al in 1994, a series of reports of both FH deficiency patients and patients with MCUL/HLRRC have described 107 variants, of which 93 are thought to be pathogenic. The most common type of mutation is missense (57%, followed by frameshifts & nonsense (27%, and diverse deletions, insertions and duplications. Here we introduce an online database detailing all reported FH sequence variants. Conclusion The FH mutation database strives to systematically

    We present a perspective to analyze mental health without either a) imposing Western illness categories or b) adopting local or "native" categories of mental distress. Our approach takes as axiomatic only that locals within any culture share a cognitive and verbal lexicon of salient positive and negative emotional experiences, which an appropriate and repeatable set of ethnographic procedures can elicit. Our approach is provisionally agnostic with respect to either Western or native nosological categories, and instead focuses on persons' relative frequency of experiencing emotions. Putting this perspective into practice in India, our ethnographic fieldwork (2006-2014) and survey analysis (N = 219) resulted in a 40-item Positive and Negative Affect Scale (PANAS), which we used to assess the mental well-being of Indigenous persons (the tribal Sahariya) in the Indian states of Rajasthan and Madhya Pradesh. Generated via standard cognitive anthropological procedures that can be replicated elsewhere, measures such as this possess features of psychiatric scales favored by leaders in global mental health initiatives. Though not capturing locally named distress syndromes, our scale is nonetheless sensitive to local emotional experiences, frames of meaning, and "idioms of distress." By sharing traits of both global and also locally-derived diagnoses, approaches like ours can help identify synergies between them. For example, employing data reduction techniques such as factor analysis-where diagnostic and screening categories emerge inductively ex post facto from emotional symptom clusters, rather than being deduced or assigned a priori by either global mental health experts or locals themselves-reveals hidden overlaps between local wellness idioms and global ones. Practically speaking, our perspective, which assesses both emotional frailty and also potential sources of emotional resilience and balance, while eschewing all named illness categories, can be deployed in

    Work-related moral distress (MD) and secondary traumatic stress syndrome (STSS) may be associated with compromised health status among health professionals, reduced productivity, and inadequate safety of care. We explored the association of MD with the severity of STSS symptoms, along with the mediating role of mental distress symptoms. Associations with emotional exhaustion and professional satisfaction were also assessed. This cross-sectional survey conducted in 206 mental health nurses (MHNs) was employed across public sector community and hospital settings in Cyprus. The analysis revealed that MD (measured by the modified Moral Distress Scale) was positively associated with both STSS (measured by the Secondary Traumatic Stress Scale) and mental distress symptoms (assessed by the General Health Questionnaire-28). The association of MD with STSS symptoms was partially mediated by mental distress symptoms. This association remained largely unchanged after adjusting for gender, age, education, rank, and intention to quit the job. Our findings provide preliminary evidence on the association between MD and STSS symptomatology in MHNs. Situations that may lead health professionals to be in moral distress seem to be mainly related to the work environment; thus interventions related to organizational empowerment of MHNs need to be developed.

    We report eight-year-old triplet girls whose clinical features included microcephaly, severe mental retardation, hypoplasia of distal phalanges of both fifth and second fingers and nail hypoplasia on second fingers, dysmorphic facial features, and partial corpus callosum agenesis. During infancy, a Pavlik harness was used for congenital hip dislocation, and they had difficulty in feeding. One had been operated for patent ductus arteriosus. To our knowledge, this rare combination has not been previously reported in triplets whose clinical features closely resemble those of Coffin-Siris syndrome. The other diagnostic possibilities are also reviewed.

    Oral health care of patients with human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS) is a growing area of concern. Information on HIV- and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing an appropriate dental curriculum on HIV and AIDS. The purpose of this study was to assess the knowledge and attitude of Indian clinical dental students towards the treatment of patients with HIV/AIDS and perceived sources of information regarding HIV-related issues. Data were collected from clinical dental students (third year, fourth year and internship) from three dental institutions in Delhi National Capital Region (NCR). The questions assessed the knowledge and attitude towards treatment of patients with HIV and the perceived source of information related to HIV. The willingness to treat HIV-positive patients among dental students was 67.0%, and 74.20% were confident of treating a patient with HIV/AIDS. The potential problems in rendering treatment to these patients were effect on the attitude of other patients (49.90%) and staff fears (52.50%). The correct knowledge regarding the infection-control practice (barrier technique) was found among only 15.50% of respondents. The respondents had sufficient knowledge regarding the oral manifestations of HIV/AIDS. There was no correlation between the knowledge and attitude score, demonstrating a gap between knowledge and attitude among dental students regarding treatment of HIV-infected patients. Appropriate knowledge has to be delivered through the dental education curriculum, which can instil confidence in students about their ability to manage HIV-positive patients. © 2014 FDI World Dental Federation.

    Although modification of behavioral practices among human immunodeficiency virus (HIV)-affected patients is important in decreasing HIV disease transmission, the knowledge, attitude, and perception studies about HIV infection rarely include persons living with HIV/acquired immuno deficiency syndrome (AIDS). To assess knowledge, attitude, and perceptions of persons living with HIV/AIDS for the disease and other epidemiological aspects. One-hundred and fifty consecutive persons living with HIV/AIDS were enrolled for this questionnaire-based cross-sectional, descriptive study. These 150 patients comprised 93 men and 57 women, aged between 14 and 78 (mean 37.13) years. The majority, 112 (74.67%) patients were between 20 and 50 years of age and 116 (77.3%) patients were either illiterate or high-school dropouts. Drivers, laborers, and self-employed comprised 69 (74.2%) patients among affected males. Only 129 (86%) respondents had heard about HIV/AIDS and knew about its heterosexual transmission. Ninety-eight (65.3%) respondents were aware of disease transmission from infected blood or needle pricks. Interestingly, 106 (70.7%) respondents were aware of the importance of using condom in preventing disease transmission. Television/radio was the most common sources of information for 135 (90%) patients. Nearly, 69% respondents disfavored disclosing their disease to friends/colleagues fearing stigmatization. Information, education, and communication activities are imperative to educate persons living with HIV/AIDS about life-long nature of the disease, modes of its transmission, and significance of preventive measures to bridge the gaps in their knowledge. While improvement in individual economic status, education, and health services remains highly desirable, mass media can play a pivotal role in creating awareness among masses.

    Dermatan sulfate (DS) plays a number of roles in a wide range of biological activities such as cell signaling and tissue morphogenesis through interactions with various extracellular matrix proteins including collagen. Mutations in the carbohydrate sulfotransferase 14 gene (CHST14) encoding CHST14/dermatan 4-O-sulfotransferase-1 (D4ST1), which is responsible for the biosynthesis of DS, cause a recently delineated form of Ehlers-Danlos syndrome (EDS, musculocontractural type 1), an autosomal recessive connective tissue disorder characterized by congenital malformations (specific craniofacial features, and congenital multiple contractures) and progressive fragility-related complications (skin hyperextensibility, bruisability, and fragility with atrophic scars; recurrent dislocations; progressive talipes or spinal deformities; and large subcutaneous hematomas). In an attempt to develop a diagnostic screening method for this type of EDS, the amount of DS in the urine of patients was analyzed. Urinary DS was quantified by an anion-exchange chromatography after treatment with DS-specific degrading enzyme. DS was not detected in the urine of patients with homo- or compound heterozygous mutations in CHST14. These results suggest that the quantification of DS in urine is applicable to an initial diagnosis of DS-defective EDS. This is the first study to perform a urinary disaccharide compositional analysis of chondroitin sulfate (CS)/DS chains in patients with EDS caused by a CHST14/D4ST1 deficiency, and demonstrated the absence of DS chains. This result suggests systemic DS depletion in this disorder, and also proposes the usefulness of a urinary disaccharide compositional analysis of CS/DS chains as a non-invasive screening method for this disorder.

    To investigate the awareness of acquired immune deficiency syndrome (AIDS) knowledge and AIDS-related behaviors among youth students in gay dating sites, and to provide evidences for AIDS prevention education through the internet. The students in gay dating sites, selected by a snowball sampling, were interviewed by questionnaires. Chi-square tests were used to analyze the awareness of AIDS knowledge among the students of different characteristics. The Logistic regression was used to analyze the factors associated with ever testing for HIV. In the study, 469 youth students in gay dating sites filled in the questionnaires, and a total of 442 (94.2%) valid samples were collected. The awareness of HIV/AIDS knowledge for the public among the youth students in gay dating sites was 83.9% (371).The awareness of HIV/AIDS knowledge for the youth students was 77.1% (341), and the rate of ever testing for HIV was 52.0% (230). The awareness of HIV/AIDS knowledge for the public in the students were different in different age groups (P=0.001), different marital statuses (Pdating sites was 75.1% (332), and the rate of multiple sexual partnerships among the youth students was 41.3% (137). Compared with homosexual orientation, sexual orientation as heterosexual (OR=0.282, 95%CI: 0.151 to 0.528) and not sure (OR=0.175, 95%CI: 0.035 to 0.885) were risk factors of ever testing for HIV. Multiple sexual partnerships (OR=2.103, 95%CI: 1.278 to 3.462) were promoting factors of ever testing for HIV. The rate of high-risk behaviors among the youth students in gay dating sites was high. The concern should be raised to heterosexual male students who had tendency to homosexual behavior. The AIDS prevention education should be developed in gay dating sites, to improve the self-protection awareness of the youth students.

Results: A total of 157 treatment-naïve patients who were followed up at our HIV/AIDS outpatient clinic were included in this study. Four patients (2.6%, had HBsAg positivity. Anti-HBc IgG and anti-HBs positivity were detected in 34% and 28.4% of the patients, respectively. No patients had anti-HCV positivity. Conclusion: The prevalence of HBsAg in HIV-positive individuals was found to be similar to that in other population-based studies in our country. Absence of anti-HCV positivity suggests that hepatitis C infection is not a major health problem in this population.

    Urinary concentrations of creatine and guanidinoacetic acid divided by creatinine are informative markers for cerebral creatine deficiency syndromes (CDSs). The renal excretion of these substances varies substantially with age and sex, challenging the sensitivity and specificity of postanalytical interpretation. Results from 155 patients with CDS and 12 507 reference individuals were contributed by 5 diagnostic laboratories. They were binned into 104 adjacent age intervals and renormalized with Box-Cox transforms (Ξ). Estimates for central tendency (μ) and dispersion (σ) of Ξ were obtained for each bin. Polynomial regression analysis was used to establish the age dependence of both μ[log(age)] and σ[log(age)]. The regression residuals were then calculated as z-scores = {Ξ - μ[log(age)]}/σ[log(age)]. The process was iterated until all z-scores outside Tukey fences ±3.372 were identified and removed. Continuous percentile charts were then calculated and plotted by retransformation. Statistically significant and biologically relevant subgroups of z-scores were identified. Significantly higher marker values were seen in females than males, necessitating separate reference intervals in both adolescents and adults. Comparison between our reconstructed reference percentiles and current standard age-matched reference intervals highlights an underlying risk of false-positive and false-negative events at certain ages. Disease markers depending strongly on covariates such as age and sex require large numbers of reference individuals to establish peripheral percentiles with sufficient precision. This is feasible only through collaborative data sharing and the use of appropriate statistical methods. Broad application of this approach can be implemented through freely available Web-based software. © 2015 American Association for Clinical Chemistry.

    Head circumference (HC) is a simple and practical measure of brain size, development and longitudinal measurements of the HC in childhood are an index of brain growth. To determine the effects of long IGF-I deficiency and treatment on HC in patients with Laron syndrome (LS). 20 untreated adult LS patients, aged 48.4±11.2 years and 13 LS patients treated between ages of 5.6±4 to 11.3±3 years were studied. 15 patients with congenital IGHD treated between age 6.1±4 and 13±4 by hGH served as controls. HC was expressed as standard deviation (SD) and Ht as SDS. HC was measured and plotted on Nellhaus charts. Linear height (Ht) was measured by a Harpenden Stadiometer. The mean HC deficit of the adult untreated LS males was -2.9±0.6 SD compared to a Ht deficit of -7.0±1.7 SDS. The HC of the LS adult females was -3.6±1 SD compared to a Ht SDS of -6.9±1.5 (pdeficit decreased only by 1.5 SDS. hGH treatment of cIGHD children increased the HC from -2.0±1.8 to 0.3±1.2 SD and the Ht SDS from -4.8±1.6 to 1.6±1.0.

    2004-04-01

    Online Mendelian Inheritance in Man (OMIM database was searched for information on clinical genetics. SUMMARY OF THE FINDINGS: In October 2003, the number of genetic syndromes associated with mental retardation reached 1,149. Considering the genetic or environmental and congenital or acquired causes of mental retardation, current diagnostic investigation is able to detect the etiology in 50 to 70% of cases. CONCLUSIONS: Diagnostic evaluation should follow a stepwise approach in order to make rational use of the expensive tools of cytogenetics, molecular biology, and neuroimaging.

    DOORS syndrome (Deafness, Onychodystrophy, Osteodystrophy, mental Retardation, Seizures) is characterized mainly by sensorineural deafness, shortened terminal phalanges with small nails of hands and feet, intellectual deficiency, and seizures. Half of the patients with all clinical features have mutations in TBC1D24. We review here the manifestations of patients clinically diagnosed with DOORS syndrome. In this cohort of 32 families (36 patients) we detected 13 individuals from 10 families with TBC1D24 mutations. Subsequent whole exome sequencing in the cohort showed the same de novoSMARCB1 mutation (c.1130G>A), known to cause Coffin-Siris syndrome, in two patients. Distinguishing features include retinal anomalies, Dandy-Walker malformation, scoliosis, rocker bottom feet, respiratory difficulties and absence of seizures, and 2-oxoglutaric aciduria in the patients with the SMARCB1 mutation. We briefly discuss the heterogeneity of the DOORS syndrome phenotype and the differential diagnosis of this condition. © 2014 Wiley Periodicals, Inc.

  10. To compare the efficacy of two kinds of Zhizhu pills in the treatment of functional dyspepsia of spleen-deficiency and qi-stagnation syndrome:a randomized group sequential comparative trial

    Science.gov (United States)

    2011-01-01

    Background In Traditional Chinese Medicine (TCM) theory, functional dyspepsia (FD) can be divided into different syndromes according to different clinical symptoms and signs, and the most common one is spleen-deficiency and qi-stagnation syndrome that can be treated by Chinese traditional patent medicine ---- two kinds of Zhizhu pills, between which the primary difference in ingredients is that one contains immature orange fruit of Citrus aurantium L.(IFCA) and the other contains that of Citrus sinensis Osbeck (IFCS). The trial's objective was to compare the efficacy of two kinds of Zhizhu pills on symptom changes in patients with FD of spleen-deficiency and qi-stagnation syndrome. Methods A randomized, group sequential, double-blinded, multicenter trial was conducted in patients with FD of spleen-deficiency and qi-stagnation syndrome at 3 hospitals in Beijing between June 2003 and May 2005. Participants were randomly allocated into two groups (IFCA group and IFCS group) in a 1:1 ratio, and respectively took one of the two kinds of Zhizhu pills orally, 6 g each time, 3 times a day, for 4 weeks. Statistical analysis was performed with use of a group sequential method, the triangular test (TT). Results A total of 163 patients were randomized, and 3 patients were excluded from analysis because of early dropouts, leaving 160 patients (IFCA group: n = 82; IFCS group: n = 78) for statistical analysis. Three interim analyses were done after 62, 116, and 160 patients had completed their 4-week treatment, respectively. At the third interim analysis, the sample path crossed the upper boundary and the trial was stopped, the cure-markedly effective rates were 45% for IFCS group and 67% for IFCA group, respectively, the one-sided p-value was 0.0036, the median unbiased estimate of the odds ratio (OR) for the benefit of IFCA relative to IFCS was 2.91 with 95%CI: 1.40 to 6.06. No adverse events were observed in the two groups. Conclusions Zhizhu pills containing IFCA was superior

    ABSTRACT Objective: To increase the level of awareness that Ehlers-Danlos/hypermobility syndrome (EDS) and vitamin D deficiency are associated with infantile fragility fractures and radiologic features that may be mistakenly reported to be caused by non-accidental trauma due to Child Abuse and Neglect (CAN). Patients and Methods: We constructed a case series, the largest to date, of infants with EDS who were vitamin D sufficient, insufficient and deficient and infants without EDS but with documented vitamin D deficiency and radiologic evidence of rickets who presented with multiple fractures originally diagnosed as being non-accidental and caused by child abuse. These infants were referred to the outpatient Bone Health Care Clinic at Boston University Medical Campus over a 6-year (2010–2015) period. We also present 6 index cases in which the court concluded that there was no convincing evidence of child abuse and the infants were returned to their parents. Institutional Review Board (IRB) approval was obtained. Results: We present 72 cases of infants with multiple fractures diagnosed to be caused by non-accidental trauma. All infants were younger than one year of age. Among them, 93%(67) had clinical evidence of EDS and/or a family history with a confirmed clinical diagnosis of at least one parent having EDS and the other 7%(5) without evidence of EDS had vitamin D deficiency/infantile rickets. Three of the EDS infants were diagnosed as osteogenesis imperfecta (OI)/EDS overlap syndrome. The most common fractures noted at diagnosis were ribs and extremity fractures (including classic metaphyseal lesions). Serum levels of 25-hydroxyvitamin D [25(OH)D] were reported in 48 infants (18.0 ± 8.5 ng/ml) and in 30 mothers (21.3 ± 11.7 ng/ml). Sixty-three percent (27) of the EDS infants who had their serum 25(OH)D measured were vitamin D deficient 25(OH)D30 ng/ml. The mean serum level for infants with vitamin D deficiency/rickets was (10.2 ± 3.0 ng/ml) Conclusion: EDS

    Williams-Beuren syndrome is a rare neurodevelopmental disorder, characterized by congenital heart defects, abnormal facial features, mental retardation with specific cognitive and behavioral profile, growth hormone deficiency, renal and skeletal anomalies, inguinal hernia, infantile hypercalcaemia. We report a case with Williams-Beuren syndrome associated with a single kidney and nephrocalcinosis complicated by hypercalcaemia. A male infant, aged 20 months presented growth retardation associated with a psychomotor impairment, dysmorphic features and nephrocalcinosis. He had also hypercalciuria and hypercalcemia. Echocardiography was normal. DMSA renal scintigraphy showed a single functioning kidney. The FISH generated one ELN signal in 20 metaphases read and found the presence of ELN deletion, with compatible Williams-Beuren syndrome.

    Full Text Available Deficiency of the organs is a vital pathophysiologic characteristic in the elderly. A core TCM aging theory is known as aging caused by spleen deficiency syndrome (SDS that can be found in ancient and modern literature. The key objectives of this study were to establish a full-scale trial to evaluate the prevalence, symptom severity, frequency, and distribution of SDS in different age groups as related to health status (healthy, subhealthy, and chronic disease to elucidate the role of spleen deficiency in the aging process and deterioration of health status. This cross-sectional observational study was conducted in 4 hospitals in China. 1390 participants aged 20–79 were interviewed by investigators who completed questionnaires recording prevalence, severity, and frequency of symptoms as well as other relevant information. The results revealed that prevalence and symptom characteristics of SDS showed regularities with increasing age and deteriorating health status. It supports the TCM concept that spleen deficiency is an important mechanism of aging, subhealth, and chronic diseases. Early recognition of the warning signs and symptoms of SDS may lead to intervention and even prevention strategies for subhealth and chronic diseases as well as promotion of healthy aging.

    Suboptimal vitamin D levels have been identified in populations with psychotic disorders. We sought to explore the relationship between vitamin D deficiency, clinical characteristics and cardiovascular disease risk factors among people with established psychosis. Vitamin D levels were measured in 324 community dwelling individuals in England with established psychotic disorders, along with measures of mental health, cardiovascular risk and lifestyle choices. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D (25-OHD) levels below 10 ng/ml (equivalent to Vitamin D as above 30 ng/ml (>50 nmol/L). The mean 25-OHD serum level was 12.4 (SD 7.3) ng/ml, (range 4.0-51.7 ng/ml). Forty nine percent (n = 158) were vitamin D deficient, with only 14 % (n = 45) meeting criteria for sufficiency. Accounting for age, gender, ethnicity and season of sampling, serum 25-OHD levels were negatively correlated with waist circumference (r = -0.220, p vitamin D deficiency. Lower vitamin D levels are associated with increased cardiovascular disease risk factors and in particular metabolic syndrome. Further research is needed to define appropriate protocols for vitamin D testing and supplementation in practice to see if this can improve cardiovascular disease risk.

    2010-08-01

    Localised duplications, involving the MECP2 locus, at Xq28 have been associated with a syndrome comprising X-linked mental retardation, hypotonia and recurrent infections in males. We now present neuroradiological evidence that progressive cerebellar degenerative changes may also be a consistent feature of this syndrome, emerging in the second decade of life. We report seven affected males, from three different families who, in addition to the previously described clinical findings, have a reduction in the volume of the white matter and mild dilatation of the lateral ventricles. Three of the older patients show a consistent cerebellar degenerative phenotype. Furthermore, we describe the first female affected with the disorder. The female was mildly affected and shows X-inactivation in the ratio of 70:30, demonstrating that X-inactivation cannot be exclusively relied upon to spare the female carriers from symptoms. In conclusion, there is a radiological phenotype associated with Xq28 duplication which clearly demonstrates progressive degenerative cerebellar disease as part of the syndrome.

    proliferation of D2 receptors. Proposal and conclusion The authors propose that D2 receptor stimulation can be accomplished via the use of Synapatmine™, a natural but therapeutic nutraceutical formulation that potentially induces DA release, causing the same induction of D2-directed mRNA and thus proliferation of D2 receptors in the human. This proliferation of D2 receptors in turn will induce the attenuation of craving behavior. In fact as mentioned earlier, this model has been proven in research showing DNA-directed compensatory overexpression (a form of gene therapy of the DRD2 receptors, resulting in a significant reduction in alcohol craving behavior in alcohol preferring rodents. Utilizing natural dopaminergic repletion therapy to promote long term dopaminergic activation will ultimately lead to a common, safe and effective modality to treat Reward Deficiency Syndrome (RDS behaviors including Substance Use Disorders (SUD, Attention Deficit Hyperactivity Disorder (ADHD, Obesity and other reward deficient aberrant behaviors. This concept is further supported by the more comprehensive understanding of the role of dopamine in the NAc as a "wanting" messenger in the meso-limbic DA system.

    To determine the clinico-demographic features and laboratory parameters of children with severe combined immunodeficiency (SCID). Study Design: Case series. Place and Duration of Study: Department of Paediatrics and Child Health, the Aga Khan University, Karachi, from July 2006 to July 2011. Methodology: Thirteen infants who were discharged with a diagnosis of SCID were inducted in the study. Their clinicodemographic features and laboratory parameters were determined. Descriptive statistics has been used for computing frequency and percentage. Results: The median age at diagnosis was five months; 5 infants presented within 3 months of life. Three-fourth (77%) were males. Most of the infants were severely malnourished (85%) at the time of presentation. More than two-thirds (69%) were products of consanguineous marriages. All subjects had severe lymphopenia (absolute lymphocyte count (ALC) ranging between 170 – 2280) and low T and B lymphocyte counts. Conclusion: SCID should be considered in infants presenting with severe and recurrent infections. Low ALC (< 2500/mm3), is a reliable diagnostic feature of SCID. These infants should be promptly referred to a facility where stem cell transplant can be done. (author)

    2010-06-01

    Deletion of short stature homeobox-containing (SHOX) gene, in the pseudoautosomal region (PAR1) of X and Y chromosomes, is an important cause of short stature. Homozygous loss of SHOX results in the more severe Langer mesomelic dysplasia, while SHOX haploinsufficiency cause a wide spectrum of short stature phenotypes, including patients with Turner syndrome, Leri Weill dyschondrosteosis (LWD), and idiopathic short stature (ISS). In Turner syndrome, haploinsufficiency of SHOX gene, as well as short stature, are present in 100%; nevertheless, SHOX deficiency accounts for only two-thirds of Turner patients' short stature. In LWD the prevalence of SHOX gene anomalies varies from 56% to 100%. This wide range might be due to different factors such as selection criteria of patients, sample size, and method used for screening SHOX mutations. The real challenge is to establish the prevalence of SHOX deficiency in ISS children given that published studies have reported this association with a very broad frequency range varying from 1.5% to 15%. An important variable in these studies is represented by the method used for screening SHOX mutations and sometimes by differences in patient selection. Short stature is present by definition in 3 out of 100 subjects; if we consider a frequency of SHOX defects of 3% among ISS, we should expect a population prevalence of 1 in 1000. This prevalence would be higher than that of GH deficiency (1:3,500) and of Turner syndrome (1:2,500 females), suggesting that SHOX deficiency could be one of the most frequent monogenetic causes of short stature.

    Mental stress induces transient endothelial dysfunction, which is an important finding for subjects at cardiometabolic risk. Thus, we tested whether aerobic exercise prevents this dysfunction among subjects with metabolic syndrome (MetS) and whether an increase in shear rate during exercise plays a role in this phenomenon. Subjects with MetS participated in two protocols. In protocol 1 (n = 16), endothelial function was assessed using brachial artery flow-mediated dilation (FMD). Subjects then underwent a mental stress test followed by either 40 min of leg cycling or rest across two randomized sessions. FMD was assessed again at 30 and 60 min after exercise or rest, with a second mental stress test in between. Mental stress reduced FMD at 30 and 60 min after the rest session (baseline: 7.7 ± 0.4%, 30 min: 5.4 ± 0.5%, and 60 min: 3.9 ± 0.5%, P exercise prevented this reduction (baseline: 7.5 ± 0.4%, 30 min: 7.2 ± 0.7%, and 60 min: 8.7 ± 0.8%, P > 0.05 vs. baseline). Protocol 2 (n = 5) was similar to protocol 1 except that the first period of mental stress was followed by either exercise in which the brachial artery shear rate was attenuated via forearm cuff inflation or exercise without a cuff. Noncuffed exercise prevented the reduction in FMD (baseline: 7.5 ± 0.7%, 30 min: 7.0 ± 0.7%, and 60 min: 8.7 ± 0.8%, P > 0.05 vs. baseline), whereas cuffed exercise failed to prevent this reduction (baseline: 7.5 ± 0.6%, 30 min: 5.4 ± 0.8%, and 60 min: 4.1 ± 0.9%, P exercise prevented mental stress-induced endothelial dysfunction among subjects with MetS, and an increase in shear rate during exercise mediated this effect.

    We report a three-generation family manifesting a previously undescribed X-linked mental retardation syndrome. Four of the six moderately retarded males have had episodes of manic-depressive psychosis. The phenotype also includes pyramidal signs, Parkinsonian features, and macroorchidism, but there are no characteristic dysmorphic facial features. Affected males do not show fragile sites at distal Xq on cytogenetic analysis, nor do they have expansions of the CGG repeats at the FRAXA, FRAXE, or FRAXF loci. Linkage analyses were undertaken, and a maximal LOD score of 3.311 at {theta} = .0 was observed with the microsatellite marker DXS1123 in Xq28. A recombination was detected in one of the affected males with DXS1691 (Xq28), which gives the proximal boundary of the localization. No distal recombination has been detected at any of the loci tested. 31 refs., 2 figs., 2 tabs.

    Williams syndrome is a multisystemic rare genetic disorder caused by deletion of 26-28 genes in the long arm of chromosome 7. It is characterized by developmental and physical abnormalities including congenital cardiovascular abnormalities, mental retardation, neurological features, growth deficiency, genitourinary manifestations, gastrointestinal problems, musculoskeletal problems, unique behavioral characteristics, and dental problems. Dental abnormalities include malocclusion, hypodontia, malformed teeth, taurodontism, pulp stones, increased space between teeth, enamel hypoplasia, and high prevalence of dental caries. Authors report a 17-year-old female patient with underlying Williams syndrome. Oral features and problems seen in the patient are listed. Malocclusion and screwdriver shaped teeth were noticed. Generalized widening of the periodontal ligament space with vital teeth was seen. This finding has not been reported in cases of Williams syndrome earlier. Precautions taken during dental treatment in patients with Williams syndrome are also discussed.

    Oculo-cerebro-renal syndrome (Lowe's syndrome) is characterized by mental and motor retardation, cataract, glaucoma and renal abnormalities. It is an X-linked recessive metabolic disease. Two brothers suffering from Lowe's syndrome are reported. Their mother with lenticular opacities and peculiar facial appearance is in concordance with the obligate carrier. The ocular changes and heridity are discussed.
