    Glycogen storage disease type II (GSDII), also referred to as Pompe disease or acid maltase deficiency, is a rare inherited condition caused by a deficiency in acid alpha-glucosidase (GAA) enzyme activity. The condition is often classified by age of presentation, with infantile and late onset variants (Laforet et al. J Neurology 55:1122-8, 2000). Late onset tends to present with progressive proximal muscle weakness and respiratory insufficiency (Winkel et al. J Neurology 252:875-84, 2005). We report two cases of biopsy confirmed adult onset GSDII, along with key Magnetic Resonance (MR) images. (orig.)

    2000-01-01

    BACKGROUND—Tic disorders presenting during adulthood have infrequently been described in the medical literature. Most reports depict adult onset secondary tic disorders caused by trauma, encephalitis, and other acquired conditions. Only rare reports describe idiopathic adult onset tic disorders, and most of these cases represent recurrent childhood tic disorders.
OBJECTIVE—To describe a large series of patients with tic disorders presenting during adulthood, to compare cl...

    Astrocytes, the most abundant glial cell type in the brain, undergo a number of roles in brain physiology; among them, the energetic support of neurons is the best characterized. Contained within astrocytes is the brain’s obligate energy store, glycogen. Through glycogenolysis, glycogen, a storage form of glucose, is converted to pyruvate that is further reduced to lactate and transferred to neurons as an energy source via MCTs. Glycogen is a multi-branched polysaccharide synthesized from the glucose uptaken in astrocytes. It has been shown that glycogen accumulates with age and contributes to the physiological ageing process in the brain. In this study, we compared glycogen distribution between young adults and geriatric mice to understand the energy consumption of synaptic terminals during ageing using computational tools. We segmented and densely reconstructed neuropil and glycogen granules within six (three 4 month old old and three 24 month old) volumes of Layer 1 somatosensory cortex mice brains from FIB-SEM stacks, using a combination of semi-automated and manual tools, ilastik and TrakEM2. Finally, the 3D visualization software, Blender, was used to analyze the dataset using the DBSCAN and KDTree Nearest neighbor algorithms to study the distribution of glycogen granules compared to synapses, using a plugin that was developed for this purpose. The Nearest Neighbors and clustering results of 6 datasets show that glycogen clusters around excitatory synapses more than inhibitory synapses and that, in general, glycogen is found around axonal boutons more than dendritic spines. There was no significant accumulation of glycogen with ageing within our admittedly small dataset. However, there was a homogenization of glycogen distribution with age and that is consistent with published literature. We conclude that glycogen distribution in the brain is not a random process but follows a function distribution.

    Full Text Available Glycogen storage disease type 2 (Pompe’s disease is an autosomal recessive, fatal glycogen storage disease presenting with hypotonia and muscle weakness. It is known that deficiency of lysosomal acid alpha-glucosidase (acid maltase leads to progressive generalised myopathy, cardiomyopathy and death in early infancy because of respiratory muscle weakness. Excessive undegradable intracellular glycogen deposition plays a role in the pathogenesis of the disease. Here we report a 3.5 month-old girl presenting with respiratory failure due to pneumonia and hypotonia, who was later diagnosed as Pompe disease.

    Full Text Available Background Late-onset glycogen storage disease typeⅡ(GSDⅡ, Pompe disease is an autosomal recessive disease exhibiting progressive proximal skeletal muscle weakness and respiratory muscle involvement, caused by deficiency of the lysosomal enzyme acid α-glucosidase (GAA. Most of patients died of respiratory failure.  Methods Eleven patients with late-onset glycogen storage disease type Ⅱ underwent respiratory function evaluation, whose diagnosis was confirmed by muscle pathology, GAA activity assay and gene analysis. Respiratory function evaluation included upright and supine position of forced vital capacity (FVC, forced expiratory volume at the first second (FEV1, maximal inspiratory pressure (MIP, maximal expiratory pressure (MEP and cough peak flow (CPF. All data were compared with predicted value. The decreased value between upright and supine position FVC ( △ FVC were calculated. The correlation between respiratory function and the age of onset, disease course, motor function, GAA activity were analyzed.  Results All of 11 patients with late-onset glycogen storage disease type Ⅱ showed declined respiratory function compared with predicted value. The upright FVC, upright FEV1, △ FVC, MIP, MEP and CPF declined in 10, 10, 8, 11, 10, and 10 patients, respectively. All patients had normal FEV1/FVC in both upright and supine position. There was no correlation between upright FVC, △ FVC and the onset age, disease course, motor function, GAA activity statistically.  Conclusions Pulmonary dysfunction is common in late-onset glycogen storage disease type Ⅱ, with restrictive ventilatory impairment more predominant, which is caused by inspiratory muscle weakness. doi: 10.3969/j.issn.1672-6731.2014.05.007

  7. Glycogenic hepatopathy in young adults: a case series

    Directory of Open Access Journals (Sweden)

    Marco Silva

    Full Text Available Glycogenic hepatopathy is a rare and underecognized complication in long-standing poorly controlled type 1 diabetes mellitus patients. This is a distinct entity from other causes of hepatomegaly and elevated liver enzymes in diabetics, such as nonalcoholic fatty liver disease. Glycogenic hepatopathy is characterized by the combination of poorly controlled diabetes, acute liver injury with marked elevation in serum aminotransferases, and the characteristic histological features on liver biopsy. It is important to distinguish this entity as it has the potential for resolution following improved glycemic control. In this report, we describe four cases of adult patients presenting elevated serum transaminases and hepatomegaly with a history of poorly controlled type I diabetes mellitus. One of the patients had also elevated amylase and lipase in the serum, without clinical or imagiologic evidence of acute pancreatitis. Liver biopsy was performed in all patients and revealed glycogenic hepatopathy. Clinician's awareness of glycogenic hepatopathy should prevent diagnostic delay or misdiagnosis and will provide better insight and management for this condition.

    Full Text Available Pityriasis rubra pilaris (PRP has always been an intriguing topic ever since its inception. It is a group of chronic disorders characterized by reddish orange plaques with pityriasiform scaling showing follicular keratoses, palmoplantar keratoderma, and sometimes, erythroderma. It occurs all over the world but with racial variations. Its incidence might vary and the age at onset, behavior, clinical appearance, and prognosis are considered to be very important for its classification. It may manifest either as Type I classical adult onset PRP, Type II atypical adult (onset PRP, or Type VI PRP (HIV-associated PRP pityriasis rubra pilaris in contrast to classical juvenile (Type III and circumscribed juvenile (Type IV encountered among children. Its diagnosis is largely clinical with microscopic pathology being a useful supplement, but it continues to be a therapeutic dilemma. We review the epidemiology of adult onset PRP here and take stock of the prevalent treatment options.

    The prevalence of food allergy is increasing in both the pediatric and adult populations. While symptom onset occurs mostly during childhood, there are a considerable number of patients whose symptoms first begin to appear after the age of 18 years. The majority of patients with adult-onset food allergy suffer from the pollen-plant allergy syndromes. Many of them manifest their allergy after exercise and consuming food to which they are allergic. Eosinophilic esophagitis, an eosinophilic inflammation of the esophagus affecting individuals of all ages, recently emerged as another allergic manifestation, with both immediate and late response to the ingested food. This review provides a condensed update of the current data in the literature on adult-onset allergy.

    Mitochondrial diseases are polymorphic entities which may affect many organs and systems. Skeletal muscle involvement is frequent in the context of systemic mitochondrial disease, but adult-onset pure mitochondrial myopathy appears to be rare. We report 3 patients with progressive skeletal mitochondrial myopathy starting in adult age. In all cases, the proximal myopathy was the only clinical feature. Mitochondrial pathology was confirmed by evidence of ragged-red fibres in muscle histochemistry, an abnormal mitochondrial morphology in electron microscopy and by exclusion of other underlying diseases. No deletions of mitochondrial DNA were found. We emphasize the need to look for a mitochondrial disorder in some non-specific myopathies starting in adult life. Images Figure 1 Figure 2 PMID:1589382

    Full Text Available Langerhans’ cell histiocytosis (LCH is a group of diseases of unknown cause resulting from abnormal proliferation of bone marrow-originated dendritic cells called histiocytes. The incidence is between 0.5-5.4 per million. More common in childhood, it is extremely rare in adults. In adults, pulmonary involvement with Langerhans’ cell histiocytosis usually occurs as a single-system disease. In this article, the clinical, radiological and histopathological findings of a 51-year-old male patient with both skin, bone and pulmonary involvement were presented and discussed with recent literature.

    2014-01-01

    Full Text Available Disabling pansclerotic morphea (DPM is a rare, severe, and mutilating form of morphea, involving the dermis, subcutaneous tissue, fat, muscle, and even bone. It is usually seen before the age of 14 years, with the patient complaining of arthralgia and stiffness at the time of onset. We report a case of unilateral adult-onset DPM with sparing of the face. Within a few months of onset, painful contracture deformities of the hand, elbow, and shoulder joints developed, impairing the patient′s normal daily activities. We are reporting this case because of the unusual presentation: DPM in an adult, with history of trauma in childhood and rapid onset of complications, is rare.

    The present paper is focusing on rare diseases manifesting in late childhood or adulthood. A part of these syndromes are not of genetic origin, such as relatively or absolutely rare infections, autoimmune diseases, tumours, or diseases due to rare environmental toxic agents. In addition, even a large proportion of genetic disorders may develop in adulthood or may have adult forms as well, affecting are almost each medical specialization. Examples are storage disorders (e.g. adult form of Tay-Sachs disease, Gaucher-disease), enzyme deficiencies (e.g. ornithin-transcarbamylase deficiency of the urea cycle disorders), rare thrombophilias (e.g. homozygous factor V. Leiden mutation, antithrombin deficiency), or some rare monogenic disorders such as Huntington-chorea and many others. It is now generally accepted that at least half of the 6-8000 "rare diseases" belong either to the scope of adult-care (e.g. internal medicine, neurology), or to "age-neutral" specialities such as ophtalmology, dermatology etc.).

    2014-03-01

    Full Text Available Patients with adult onset non-familial progressive ataxia are classified in sporadic ataxia group. There are several disease categories that may manifest with sporadic ataxia: toxic causes, immune-mediated ataxias, vitamin deficiency, infectious diseases, degenerative disorders and even genetic conditions. Considering heterogeneity in the clinical spectrum of sporadic ataxias, the correct diagnosis remains a clinical challenge. In this review, the different disease categories that lead to sporadic ataxia with adult onset are discussed with special emphasis on their clinical and neuroimaging features, and diagnostic criteria.

    Full Text Available Objective To evaluate the effect of Myozyme on one ventilator dependent patient with late-onset glycogen storage disease typeⅡ (GSDⅡ.  Methods Myozyme infusion was administered based on manufacturer's recommendations at 20 mg/kg every 2 to 4 weeks, beginning at actual body weight, and was continuously treated for 6 times. No premedication was performed except 5 mg dexamethasone was administered at the first use of Myozyme. Clinical assessment was completed every day and was lasted for 16 months including motor function, the time free of ventilation, and the change of respiration parameters.  Results Myozyme was well tolerated without adverse reactions. Pain on shoulder began to alleviate the next day after taking Myozyme. With the prolonged time and increased number of taking drugs, the time free of ventilation and doing in-situ stepping prolonged, and the speed of stepping in-situ also increased. Besides, the strength of lifting the upper limbs increased, and both the time and speed of walking free of ventilation prolonged. The maximus curative effect occured at the 7th month (3 months after drug withdrawal after treatment and returned to pre-treatment levels at the 8th month (4 months after drug withdrawal. The pain on shoulder was the first symptom that got improved, and the fastest symptom that returned to baseline.  Conclusions Myozyme has positive effect on ventilated patients with late-onset glycogen storage disease type Ⅱ. doi: 10.3969/j.issn.1672-6731.2014.05.009

    Full Text Available BACKGROUND: Respiratory infections in early life are associated with an increased risk of developing asthma but there is little evidence on the role of infections for onset of asthma in adults. The objective of this study was to assess the relation of the occurrence of respiratory infections in the past 12 months to adult-onset asthma in a population-based incident case-control study of adults 21-63 years of age. METHODS/PRINCIPAL FINDINGS: We recruited all new clinically diagnosed cases of asthma (n = 521 during a 2.5-year study period and randomly selected controls (n = 932 in a geographically defined area in South Finland. Information on respiratory infections was collected by a self-administered questionnaire. The diagnosis of asthma was based on symptoms and reversible airflow obstruction in lung function measurements. The risk of asthma onset was strongly increased in subjects who had experienced in the preceding 12 months lower respiratory tract infections (including acute bronchitis and pneumonia with an adjusted odds ratio (OR 7.18 (95% confidence interval [CI] 5.16-9.99, or upper respiratory tract infections (including common cold, sinusitis, tonsillitis, and otitis media with an adjusted OR 2.26 (95% CI 1.72-2.97. Individuals with personal atopy and/or parental atopy were more susceptible to the effects of respiratory infections on asthma onset than non-atopic persons. CONCLUSIONS/SIGNIFICANCE: This study provides new evidence that recently experienced respiratory infections are a strong determinant for adult-onset asthma. Reducing such infections might prevent onset of asthma in adulthood, especially in individuals with atopy or hereditary propensity to it.

    Full Text Available Moyamoya disease is a progressive steno-occlusive disease of bilateral carotid forks with the formation of fine collateral vascular network and is an angiographic diagnosis. We analyzed case records of 11 patients with "adult-onset moyamoya disease." Six patients presented with intracranial hemorrhage (intracerebral and/or intraventricular and 5 with focal ischemia. Angiography revealed bilateral Internal carotid artery involvement in 8 patients and unilateral involvement in 3. Posterior cerebral artery involvement was seen in 3 patients. Saccular aneurysm involving posterior circulation was seen in only 1 patient. Although rare, adult-onset moyamoya disease should be considered as one of the causes for intracerebral and intraventricular hemorrhage in adults.

    We describe a case with adult onset motor tics after peripheral trauma. A 43-year-old man suffered a left shoulder dislocation during a motorcycle accident 21 years ago. Within 2 weeks after the injury, he noticed the gradual onset of involuntary jerking movements of his left shoulder, which was markedly exacerbated after second left shoulder injury 2 years later. The involuntary movements are phenomenologically identical to tics typically associated with Tourette syndrome (TS), but without the involvement of any other body part and without phonic tics or the typical TS co-morbidities, such as attention deficit or obsessive-compulsive disorder.

    BACKGROUND Little is known about adult-onset opsoclonus-myoclonus syndrome (OMS) outside of individual case reports. OBJECTIVE To describe adult-onset OMS. DESIGN Review of medical records (January 1, 1990, through December 31, 2011), prospective telephone surveillance, and literature review (January 1, 1967, through December 31, 2011). SETTING Department of Neurology, Mayo Clinic, Rochester, Minnesota. PATIENTS Twenty-one Mayo Clinic patients and 116 previously reported patients with adult-onset OMS. MAIN OUTCOME MEASURES Clinical course and longitudinal outcomes. RESULTS The median age at onset of the 21 OMS patients at the Mayo Clinic was 47 years (range, 27-78 years); 11 were women. Symptoms reported at the first visit included dizziness, 14 patients; balance difficulties, 14; nausea and/or vomiting, 10; vision abnormalities, 6; tremor/tremulousness, 4; and altered speech, 2. Myoclonus distribution was extremities, 15 patients; craniocervical, 8; and trunk, 4. Cancer was detected in 3 patients (breast adenocarcinoma, 2; and small cell lung carcinoma, 1); a parainfectious cause was assumed in the remainder of the patients. Follow-up of 1 month or more was available for 19 patients (median, 43 months; range, 1-187 months). Treatment (median, 6 weeks) consisted of immunotherapy and symptomatic therapy in 16 patients, immunotherapy alone for 2, and clonazepam alone for 1. Of these 19 patients, OMS remitted in 13 and improved in 3; 3 patients died (neurologic decline, 1; cancer, 1; and myocardial infarction, 1). The cause of death was of paraneoplastic origin in 60 of 116 literature review patients, with the most common carcinomas being lung (33 patients) and breast (7); the most common antibody was antineuronal nuclear antibody type 2 (anti-Ri, 15). Other causes were idiopathic in origin, 38 patients; parainfectious, 15 (human immunodeficiency virus, 7); toxic/metabolic, 2; and other autoimmune, 1. Both patients with N -methyl-D-aspartate receptor antibody had

    Two adult patients with type I glycogen storage disease (I-GSD) had chronic renal disease with heavy proteinuria. Renal biopsies showed focal glomerular sclerosis, interstitial fibrosis, tubular atrophy or vacuolation, and prominent arteriosclerosis. Marked glomerular hypertrophy was demonstrated histometrically. Oil red O staining in one patient revealed numerous lipid deposits in the glomerular mesangium, tubular epithelial cells and interstitium. Electron microscopy in the other patient revealed diffuse thickening of the glomerular basement membrane (GBM) and lipid droplets within the mesangium. The glomerular hypertrophy, thickening of the GBM, and subsequent sclerosis were similar to those in insulin-dependent diabetes mellitus. These findings may explain the similarities between the natural histories of renal involvement in the two disorders. Particularly, glomerular hypertrophy may be a key step leading to glomerular sclerosis, which is the predominant finding I-GSD. Hyperlipidemia, which is commonly seen in I-GSD, may also accelerate the glomerular sclerosing process.

    Full Text Available The annual incidence of adult-onset Still's disease (AOSD worldwide is 0.16 cases per 100,000 persons. Its leading symptoms are joint involvement, fever, skin rash, and neutrophilic leukocytosis in the absence of rheumatoid factor and anticyclic citrullinated peptide antibodies in serum and synovial fluid. In its initial stage, there may be monoarthritis more commonly of the wrist, hip, or knee. Then the lesion assumes the pattern of oligo- or polyarthritis. Musculoskeletal involvement appearing as arthralgia, arthritis, and myalgia is noted in all patients. In the majority of patients, articular involvement progresses and destructive polyarthritis develops. Symmetric involvement of the carpophalangeal and distal interphalangeal joints is frequently detected. Skin lesion manifests itself as maculopapular or roseolous rashes on the chest, back, shoulders, occasionally on the legs, or in the areas of mechanical irritation. A sore throat with the signs of pharyngitis is a characteristic early symptom of the disease. There may be involvements of the liver, cardiovascular system, lung, as well as lymphadenopathy, or splenomegaly. The chronic course of the disease is more frequently noted.The paper describes two cases of AOSD. One case demonstrates that the physician has no experience in diagnosing and managing patients with AOSD, resulting in the misinterpretation of the increase in disease activity when the subclinical doses of methotrexate (MT are used, which has been regarded as a therapeutic complication. The use of the adequate dose of MT could achieve a clinical and laboratory remission and discontinue glucocorticoids (GC.In the other case of recurrent AOSD and mild clinical symptoms, the unreasonable use of high GC doses gave rise to adverse reactions.

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    Nemaline myopathy is a rare congenital myopathy that generally presents in childhood. We report a case of a 44-year-old man who presented with severe hypoxic hypercapnic respiratory failure as the initial manifestation of nemaline myopathy. After starting noninvasive ventilation, his pulmonary function test results improved substantially, and over the 4 years since diagnosis his respiratory function remained stable. There are few reported cases of respiratory failure in patients with adult-onset nemaline myopathy, and the insidious onset in this case is even more unusual. This case highlights the varied presenting features of adult-onset nemaline myopathy and that noninvasive ventilation improves respiratory function.

    We report the case of a 23-year-old man diagnosed with adult-onset idiopathic chondrolysis of the hip. Chondrolysis of the hip is a disorder most frequently seen in children who have suffered with slipped capital femoral epiphyses. Idiopathic chondrolysis of the hip is extremely rare and to our knowledge, its onset has never been documented in adults aged over 20. With reference to the available medical literature, we summarise the current clinical management of this unusual but important cause of young adult hip pain.

    Adult Onset Still’s Disease (AOSD) is a rare inflammatory syndrome mostly seen in young adults. Known for its wide range of clinical manifestations, AOSD often presents with nonremitting systemic signs and symptoms. Many rare case associations have been described with AOSD, but only few with pure red cell aplasia (PRCA). We are presenting a fourth known case of a young female adult with AOSD and PRCA in the literature.

    A 62-year-old man was hospitalized for acute rheumatic fever. He had previously suffered from rheumatic fever at 15 years of age. The rheumatic fever was complicated by carditis, which caused valve disease that required surgical treatment. The incidence of rheumatic fever has decreased in most developed countries with improvements in sanitary conditions. The low incidence of this disease makes a timely and accurate diagnosis difficult. Due to the fact that both the first occurrence and recurrence of acute rheumatic fever can occur in the elderly and adults, this potential disease should not be overlooked when making a differential diagnosis.

    Fetal alcohol exposure may impair growth, development, and function of multiple organ systems and is encompassed by the term fetal alcohol spectrum disorders (FASD). Research has so far focused on the mechanisms, prevention, and diagnosis of FASD, while the risk for adult-onset chronic diseases in individuals exposed to alcohol in utero is not well explored. David Barker's hypothesis on Developmental Origins of Health and Disease (DOHaD) suggests that insults to the milieu of the developing fetus program it for adult development of chronic diseases. In the 25 years since the introduction of this hypothesis, epidemiological and animal model studies have made significant advancements in identifying in utero developmental origins of chronic adult-onset diseases affecting cardiovascular, endocrine, musculoskeletal, and psychobehavioral systems. Teratogen exposure is an established programming agent for adult diseases, and recent studies suggest that prenatal alcohol exposure correlates with adult onset of neurobehavioral deficits, cardiovascular disease, endocrine dysfunction, and nutrient homeostasis instability, warranting additional investigation of alcohol-induced DOHaD, as well as patient follow-up well into adulthood for affected individuals. In utero epigenetic alterations during critical periods of methylation are a key potential mechanism for programming and susceptibility of adult-onset chronic diseases, with imprinted genes affecting metabolism being critical targets. Additional studies in epidemiology, phenotypic characterization in response to timing, dose, and duration of exposure, as well as elucidation of mechanisms underlying FASD-DOHaD inter relation, are thus needed to clinically define chronic disease associated with prenatal alcohol exposure. These studies are critical to establish interventional strategies that decrease incidence of these adult-onset diseases and promote healthier aging among individuals affected with FASD.

    Full Text Available Background: Few studies have attempted to delineate the clinical profile of multiple Sclerosis (MS among people of Asia. This study sought to identify the characteristics of early-onset Multiple Sclerosis (EOMS comparison to adult-onset form (AOMS in Isfahan, IRAN. Methods: This prospective study was conducted on 104 youths with multiple sclerosis beginning before the age of 16 years and 123 patients with adult-onset multiple sclerosis. Patients were observed for a mean period of 5 years. The common presenting symptoms, MRI finding, course of disease and disability score were compared between the two groups. Results: The mean onset age of disease in youths and adults were 14 ± 1.9 and 27.7 ± 8.06 years, respectively. Female/male ratio was 4.47:1 in EOMS and 3.92:1 in AOMS, this ratio was 7:1 in early childhood MS (≤ 10 year. The most common presenting symptom was optic neuritis in the EOMS group and paresthesia in AOMS. Optic neuritis was common in AOMS too, but brainstem/cerebellar signs were more common in EOMS than AOMS. Seizure occurred more frequently in EOMS than in the AOMS group (12.6% vs. 1.6%, respectively, p < 0.001. MRI showed that brainstem plaques were more prevalent in the EOMS compared with the AOMS group. Conclusions: It was concluded that early-onset MS does not significantly differ from adult form in terms of major clinical manifestation and course of disease, however Seizure is more common in EOMS, and brainstem and cerebellar symptoms as presenting symptom are more common.

    Abstract Myasthenia gravis (MG) is an autoimmune neuromuscular junction disorder which is characterized by fluctuating muscle fatigue. However, the association of MG with nemaline myopathy is rarely reported. Here we report a case of MG coexisting with adult-onset nemaline myopathy. A 55-year-old man endured fluctuating muscle weakness with positive acetylcholine receptor and titin antibodies. After the patient was administrated cholinergic drugs and immunosuppression, the muscle weakness of the patient had mildly been alleviated. Electromyography showed a progressive decrement in the amplitude of muscle action potential at low frequency. Muscle biopsy showed numerous nemalines in the muscle fibers. This is the first reported case of nemalines present in the muscle fibers of adult patient with MG. The pathogenesis of nemaline may be related to titin antibody in adult-onset nemaline myopathy with MG. PMID:26825889

    Adult Still's Disease was first described in 1971 by Bywaters in fourteen adult female patients who presented with symptoms indistinguishable from that of classic childhood Still's Disease (Bywaters, 1971). George Still in 1896 first recognized this triad of quotidian (daily) fevers, evanescent rash, and arthritis in children with what later became known as juvenile inflammatory arthritis (Still, 1990). Adult Onset Still's Disease (AOSD) is an inflammatory condition of unknown etiology characterized by an evanescent rash, quotidian fevers, and arthralgias. Numerous infectious agents have been associated with its presentation. This case is to our knowledge the first presentation of AOSD in the setting of Rocky Mountain Spotted Fever. Although numerous infectious agents have been suggested, the etiology of this disorder remains elusive. Nevertheless, infection may in fact play a role in triggering the onset of symptoms in those with this disorder. Our case presentation is, to our knowledge, the first case of Adult Onset Still's Disease associated with Rocky Mountain spotted fever (RMSF). PMID:20811570

    Pigmentary type of orthochromatic leukodystrophy (POLD) is an adult-onset leukodystrophy, characterized pathologically by the presence of glial and microglial cytoplasmic pigment inclusions. The complete phenotype, genotype and pathogenetic mechanisms in POLD have not been elucidated. We followed for 18 years a woman with autopsy-proven POLD, who presented with 'frontal' dementia and spasticity. Her further course was marked by progressive mutism, apraxia and seizures. Her sister had died of the same disease after a much more rapidly progressing course. These sisters had primary infertility with pathologic evidence of streak ovaries. Diagnosis was confirmed in both cases by post-mortem examination. POLD is a rare cause of adult-onset leukodystrophy presenting with dementia. Ovarian dysgenesis is extremely rare in the absence of demonstrable chromosomal abnormalities and extends the clinical spectrum of POLD.

    The olfactory epithelium (OE) contains neural precursor cells which can be easily harvested from a minimally invasive nasal biopsy, making them a valuable cell source to study human neural cell lineages in health and disease. Glycogen synthase kinase-3 (GSK-3) has been implicated in the etiology and treatment of neuropsychiatric disorders and also in the regulation of murine neural precursor cell fate in vitro and in vivo. In this study, we examined the impact of decreased GSK-3 activity on the fate of adult human OE neural precursors in vitro. GSK-3 inhibition was achieved using ATP-competitive (6-bromoindirubin-3'-oxime and CHIR99021) or substrate-competitive (TAT-eIF2B) inhibitors to eliminate potential confounding effects on cell fate due to off-target kinase inhibition. GSK-3 inhibitors decreased the number of neural precursor cells in OE cell cultures through a reduction in proliferation. Decreased proliferation was not associated with a reduction in cell survival but was accompanied by a reduction in nestin expression and a substantial increase in the expression of the neuronal differentiation markers MAP1B and neurofilament (NF-M) after 10 days in culture. Taken together, these results suggest that GSK-3 inhibition promotes the early stages of neuronal differentiation in cultures of adult human neural precursors and provide insights into the mechanisms by which alterations in GSK-3 signaling affect adult human neurogenesis, a cellular process strongly suspected to play a role in the etiology of neuropsychiatric disorders.

  3. Season of Birth and Risk for Adult Onset Glioma

    2010-04-01

    Full Text Available Adult onset glioma is a rare cancer which occurs more frequently in Caucasians than African Americans, and in men than women. The etiology of this disease is largely unknown. Exposure to ionizing radiation is the only well established environmental risk factor, and this factor explains only a small percentage of cases. Several recent studies have reported an association between season of birth and glioma risk. This paper reviews the plausibility of evidence focusing on the seasonal interrelation of farming, allergies, viruses, vitamin D, diet, birth weight, and handedness. To date, a convincing explanation for the occurrence of adult gliomas decades after a seasonal exposure at birth remains elusive.

    Full Text Available "Petrified ears" or calcification of auricular cartilage is an uncommonly reported condition. The most common causes of this phenomenon are local trauma, frost bite, and inflammation. Adrenal insufficiency is the most frequent systemic disease associated with auricular calcification. We present a case of idiopathic adult-onset pituitary insufficiency with hypocortisolism and bilateral auricular calcification. Recognition of the association between auricular calcification and adrenal insufficiency can be an important step toward the identification of a life-threatening cortisol deficiency.

    Full Text Available Lipodystrophy is a group of metabolic disorders, possibly caused by autoimmune disease. In this report, we describe a case of adult-onset acquired partial lipodystrophy accompanied by rheumatoid arthritis without a family history. Interestingly, immunohistochemical staining revealed dense infiltration of IL-27-producing cells as well as MMP-7- and MMP-28-expressing cells, both of which have been reported to facilitate the development of autoimmune disease. Our present case might suggest possible mechanisms for acquired partial lipodystrophy.

    To compare the maternal and fetal outcomes between childhood-onset and adult-onset systemic lupus erythematosus (SLE), we reviewed the medical records of SLE pregnant women treated from January 2005 to August 2013. For comparison, patients were allocated to one of the two groups, those pregnant patients with SLE onset before 18 years of age (childhood-onset) and ≥18 years (adult-onset). The patients were evaluated at least once in each trimester and postpartum. Relevant maternal and fetal outcomes were extracted, such as lupus flare, preeclampsia/eclampsia, rate of liveborns, fetal loss (spontaneous abortion and stillbirth), term delivery, preterm birth, neonatal death, low birth weight, low birth weight at term, and congenital malformations. We studied 186 pregnancies (in 180 women), 58 of them had childhood-onset SLE, and the remaining 128 had adult-onset SLE. The rate of maternal and fetal complications was similar in both groups. Multivariate analysis showed that active SLE before pregnancy, primigravida, renal flare, preeclampsia, lupus flare, anticardiolipin antibodies, and low serum complement were associated with an increased risk of poor maternal and fetal outcomes. The diagnosis of childhood-onset had no impact on maternal-fetal outcome. The maternal and fetal outcome in women with childhood-onset SLE is similar to that reported in women with adult-onset SLE. Pregnancy in women with childhood-onset SLE should not be contraindicated if the disease is well controlled.

    Glycogen storage disease type II (GSDII) is a lysosomal storage disorder caused by acid alpha-1,4-glucosidase deficiency and associated with recessive mutations in its coding gene GAA. Few studies have provided so far a detailed phenotypical characterization in late onset GSDII (LO-GSDII) patients. Genotype-phenotype correlation has been previously attempted with controversial results. We aim to provide an in-depth description of a cohort (n = 36) of LO-GSDII patients coming from the north of Italy and compare our population's findings to the literature. We performed a clinical record-based retrospective and prospective study of our patients. LO-GSDII in our cohort covers a large variability of phenotype including subtle clinical presentation and did not differ significantly from previous data. In all patients, molecular analysis disclosed GAA mutations, five of them being novel. To assess potential genotype-phenotype correlations we divided IVS1-32-13T>G heterozygous patients into two groups following the severity of the mutations on the second allele. Our patients harbouring "severe" mutations (n = 21) presented a strong tendency to have more severe phenotypes and more disability, more severe phenotypes and more disability, higher prevalence of assisted ventilation and a shorter time of evolution to show it. The determination of prognostic factors is mandatory in order to refine the accuracy of prognostic information, to develop follow-up strategy and, more importantly, to improve the decision algorithm for enzyme replacement therapy administration. The demonstration of genotype-phenotype correlations could help to reach this objective. Clinical assessment homogeneity is required to overcome limitations due to the lack of power of most studies.

    The purpose of the study is to compare demographics, intensive care unit (ICU) admission characteristics, and ICU outcomes among adults with childhood-onset chronic conditions (COCCs) admitted to US pediatric and adult ICUs. Retrospective cross-sectional analyses of 6088 adults aged 19 to 40 years admitted in 2008 to 70 pediatric ICUs that participated in the Virtual Pediatric Intensive Care Unit Performance Systems and 50 adult ICUs that participated in Project IMPACT. Childhood-onset chronic conditions were present in 53% of young adults admitted to pediatric units, compared with 9% of those in adult units. The most common COCC in both groups were congenital cardiac abnormalities, cerebral palsy, and chromosomal abnormalities. Adults with COCC admitted to pediatric units were significantly more likely to be younger, have lower functional status, and be nontrauma patients than those in adult units. The median ICU length of stay was 2 days, and the intensive care unit mortality rate was 5% for all COCC patients with no statistical difference between pediatric or adult units. There are marked differences in characteristics between young adults with COCC admitted to pediatric ICUs and adult ICUs. Barriers to accommodating these young adults may be reasons why many such adults have not transitioned from pediatric to adult critical care. Copyright © 2014 Elsevier Inc. All rights reserved.

    1999-01-01

    Full Text Available Twenty-four cases of sporadic olivo-ponto-cerebellar atrophy (OPCA of adult onset were studied over a period of two years. Results suggest that this disorder has its usual onset in the 5th and 6th decade of life with a male: female ratio of 2:1. It manifests clinically with gait ataxia in all, dysarthria, other cerebellar signs and autonomic involvement in vast majority. There were features of basal ganglia involvement in some. No known identifiable environmental cause was found and genetically they are quite distinct from the known autosomal dominant spinocerebellar ataxias though sporadic occurrence in recessive inheritance or a de novo mutation could not be ruled out completely, but it is unlikely.

    2009-04-01

    Tic disorders are commonly considered to be childhood syndromes. Newly presenting tic disorders during adulthood are uncommon and mostly described in relation to an acquired brain lesion or as incidental tics, particularly in context with other neurological or psychiatric diseases. Tic disorder involving the ears is extremely uncommon with only few studies in English literature. In the present case, we describe an adult patient with new-onset idiopathic tics disorder involving both ears, causing social embarrassment. In addition, our patient had recent onset of the tics without any childhood or family history of tic disorders. The single most important component of management is an accurate diagnosis. At the same time, tics should be differentiated from other movement disorders such as chorea, stereotypy, and dystonias.

    2009-01-01

    Full Text Available We report an unusual case of sporadic adult onset cerebellar ataxia with hypogonadism. A 40-year-old unmarried man presented with progressive ataxia and dysarthria along with complaints of non-development of secondary sexual characteristics and erectile dysfunction. There were complaints of intermittent diarrhea. Clinical examination revealed a pan-cerebellar syndrome with features of hypoandrogenism. No eye movement abnormalities were evident. There were signs of malabsorption. Investigations confirmed the presence of auto-antibodies found in celiac disease, and a duodenal biopsy confirmed the same. Hypoandrogenism was postulated to be due to hypergonadotropic hypogonadism which has been mentioned in a few patients of celiac disease. However, the pattern seen in our patient was of a hypogonadotropic hypogonadism. This is probably secondary to an autoimmune hypophysitis seen in some patients in the absence of other clinical manifestations. Autoantibody testing should be a diagnostic necessity in any adult with a sporadic cerebellar ataxia.

    2016-01-01

    Full Text Available Adult Onset Still’s Disease (AOSD, an adult variant of systemic onset juvenile idiopathic arthritis, is a rare systemic inflammatory disorder of unknown aetiology. The rarity of this disease is associated with low index of suspicion and delayed diagnosis in patients suffering from it and in the presence of atypical features the diagnosis can be further challenging. This is a case report on a 24-year-old woman, who was a diagnostic dilemma for 2 years due to the nonspecific symptoms of recurrent fever, generalized maculopapular persistent pruritic and tender rash, and polyarthralgia. She was initially diagnosed as leukocytoclastic vasculitis on a skin biopsy and was managed by a dermatologist with various medications including NSAIDs, hydroxychloroquine, dapsone, colchicine, cyclosporine, and high doses of oral steroids with minimal response. Subsequently, she has had multiple admissions with similar symptoms with raised inflammatory markers and negative septic workup. On one occasion, her iron study revealed hyperferritinaemia which led to the suspicion of AOSD. Once the rheumatic fever and infectious, malignant, autoimmune, and lymphoproliferative disorders were excluded, she was diagnosed as probable AOSD and managed successfully with IL-1 (interleukin-1 receptor antagonist, Anakinra, with remarkable and lasting response both clinically and biochemically.

    Full Text Available Mariam Siddiqui,1 Michael S Putman,2 Anisha B Dua,11Department of Rheumatology, 2Department of Internal Medicine, The University of Chicago Medical Center, Chicago, IL, USA Abstract: Adult-onset Still's disease (AOSD – a multi-systemic inflammatory condition characterized by high fevers, polyarthritis, an evanescent rash, and pharyngitis – has been a challenging condition to diagnose expediently and treat effectively. Questions remain regarding the underlying pathophysiology and etiology of AOSD. Pathognomonic diagnostic tests and reliable biomarkers remain undiscovered. Over the past decade, important progress has been made. Diagnostic criteria employing glycosylated ferritin have improved specificity. More important, novel biologic therapies have offered important clues to AOSD's underlying pathophysiology. Cytokine-specific biologic therapies have been instrumental in providing more effective treatment for disease refractory to conventional treatment. While IL-1 therapy has demonstrated efficacy in refractory disease, novel therapies targeting IL-6 and IL-18 show great promise and are currently under investigation.

    Full Text Available Food allergy can result in life-threatening anaphylaxis. Atopic dermatitis (AD causes intense itching and impaired quality of life. Previous studies have shown that patients with classical early-onset AD tend to develop food allergy and that 10% of adults with food allergies have concomitant AD. However, it is not known whether late-onset food allergy leads to adult-onset AD, a recently recognized disease entity. Using an initial cohort of one-million subjects, this study retrospectively followed-up 2851 patients with food allergy (age > 12 years for 14 years and compared them with 11,404 matched controls. While 2.8% (81 of the 2851 food allergy patients developed AD, only 2.0% (227 of the 11,404 controls developed AD. Multivariate regression analysis showed that food allergy patients were more likely to develop AD (adjusted hazard ratio = 2.49, p < 0.0001. Controls had a 1.99% risk of developing AD, while food allergy patients had a significantly higher risk (7.18% and 3.46% for patients with ≥3 and <3 food allergy claims, respectively of developing adult-onset AD. This is the first study to describe the chronological and dose-dependent associations between food allergy in adolescence and the development of adult-onset AD.

    Background. There are limited epidemiological studies evaluating the effect of age at onset on disease features in vitiligo. Objectives. To identify factors associated with adult onset vitiligo in comparison with childhood onset vitiligo. Patients and Methods. We retrospectively collected medical records of 191 patients. Such records included clinical examination, personal and familial medical history, laboratory evaluations, concomitant vitiligo treatment and drug assumption. Results. 123 patients with a disease onset after the age of 40 (adult onset vitiligo) were compared with 68 patients who developed vitiligo before the age of 12 (childhood onset vitiligo). Multivariate analysis revealed that personal history of thyroid diseases (P = 0.04; OR 0.4), stress at onset (P = 0.002; OR = 0.34), personal history of autoimmune thyroid disease (ATD) (P = 0.003; OR = 0.23), and thyroid nodules (P = 0.001; OR 0.90) were independently associated with adult onset vitiligo, whereas family history of dermatological diseases (P = 0.003; OR = 2.87) and Koebner phenomenon (P < 0.001; OR = 4.73) with childhood onset vitiligo. Moreover, in the adult onset group, concomitant thyroid disease preceded vitiligo in a statistically significant number of patients (P = 0.014). Conclusions. Childhood onset and adult onset vitiligo have different clinical features. In particular, ATD and thyroid nodules were significantly associated with adult onset vitiligo, suggesting that a thyroid screening should be recommended in this group of patients.

    Abstract Adult-onset Still's disease (AOSD) is often refractory to standard therapy. Anakinra (ANK), an interleukin-1 receptor antagonist, has demonstrated efficacy in single cases and small series of AOSD. We assessed the efficacy of ANK in a series of AOSD patients. Multicenter retrospective open-label study. ANK was used due to lack of efficacy to standard synthetic immunosuppressive drugs and in some cases also to at least 1 biologic agent. Forty-one patients (26 women/15 men) were recruited. They had a mean age of 34.4 ± 14 years and a median [interquartile range (IQR)] AOSD duration of 3.5 [2–6] years before ANK onset. At that time the most common clinical features were joint manifestations 87.8%, fever 78%, and cutaneous rash 58.5%. ANK yielded rapid and maintained clinical and laboratory improvement. After 1 year of therapy, the frequency of joint and cutaneous manifestations had decreased to 41.5% and to 7.3% respectively, fever from 78% to 14.6%, anemia from 56.1% to 9.8%, and lymphadenopathy from 26.8% to 4.9%. A dramatic improvement of laboratory parameters was also achieved. The median [IQR] prednisone dose was also reduced from 20 [11.3–47.5] mg/day at ANK onset to 5 [0–10] at 12 months. After a median [IQR] follow-up of 16 [5–50] months, the most important side effects were cutaneous manifestations (n = 8), mild leukopenia (n = 3), myopathy (n = 1), and infections (n = 5). ANK is associated with rapid and maintained clinical and laboratory improvement, even in nonresponders to other biologic agents. However, joint manifestations are more refractory than the systemic manifestations. PMID:26426623

    A 42-year-old man presented with a history of repeated episodes of consciousness disturbance for 5 years. The MRI showed abnormally high signal intensities on T2-weighted images at bilateral cingulate gyri, temporal lobes and insular regions, mimicking the finding of herpes simplex encephalitis. Hyperammonemia was disclosed. Serial work-up led to the diagnosis of adult-onset citrullinemia, deficiency of argininosuccinate synthetase. The clinical symptoms improved after diet control and medication. Follow-up MRI showed resolution of the abnormal signal intensities. The MRI findings of citrullinemia and other urea-cycle defects might be attributed to hyperammonemic encephalopathy, but the manifestations were varied. Similar distribution of the abnormalities in the MRI could be found in some reported cases and indicates probably vulnerable sites of hyperammonemic brain injury. (orig.)

    Liver abnormalities in the course of Adult Onset Still's Disease (AOSD), both in form of hepatomegaly and elevation of hepatic enzymes, have been reported in up to three-quarts of the affected patients. These abnormalities may reflect disease activity or may be induced by drugs. Only in a few of this patients a liver biopsy was performed. However liver histology has shown, generally, non specific abnormalities or even normal pictures. We have recently observed a 47-year-old woman with a febrile illness started five months before, who after pertinent investigation was diagnosed as AOSD (according to criteria of Yamaguchi et al.). Apart from laboratory findings characteristic of an inflammatory disease, in absence of drug therapies the biochemical data showed raised levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and aminoglutamil transferase. Serological tests for either viral hepatitis viruses (HAV, HBV, HCV) or other viruses were negative. Ultrasonographic examination of gallbladder and bile ducts did not find gallstones or other abnormalities. A liver biopsy was performed, which histopathologic examination showed moderate fatty methamorphosis with focal areas of hepatocellular swelling with minimal necrosis, mild Kuppfer cell hyperplasia, portal and sinusoidal infiltrates of mononuclear cells. This picture consisted with the diagnosis of an acute unspecific reactive hepatitis.

  6. Comparing endophenotypes in adult-onset primary torsion dystonia.

    Adult-onset primary torsion dystonia (AOPTD) has an autosomal dominant pattern of inheritance with markedly reduced penetrance; the genetic causes of most forms of AOPTD remain unknown. Endophenotypes, markers of sub-clinical gene carriage, may be of use detecting non-manifesting gene carriers in relatives of AOPTD patients. The aim of this study was to compare the utility of the spatial discrimination threshold (SDT) and temporal discrimination threshold (TDT) as potential endophenotypes in AOPTD. Data on other published candidate endophenotypes are also considered. Both SDT and TDT testing were performed in 24 AOPTD patients and 34 of their unaffected first degree relatives; results were compared with normal values from a control population. Of the 24 AOPTD patients 5 (21%) had abnormal SDTs and 20 (83%) had abnormal TDTs. Of the 34 first degree relatives 17 (50%) had abnormal SDTs and 14 (41%) had abnormal TDTs. Discordant results on SDT and TDT testing were found in 16 (67%) AOPTD patients and 21 (62%) first degree relatives. TDT testing has superior sensitivity compared to SDT testing in AOPTD patients; although false positive TDTs are recognised, the specificity of TDT testing in unaffected relatives is not determinable. The high level of discordance between the two tests probably relates methodological difficulties with SDT testing. The SDT is an unreliable AOPTD endophenotype; TDT testing fulfils criteria for a reliable endophenotype with a high sensitivity.

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder of unknown etiology, and approximately 60-70% of patients may develop a chronic polyphasic form of the disease or a chronic polyarthritis. Due to rarity of disease, treatment of AOSD is not based on controlled study, but on case based experiences. Areas covered: Recently, the application of anti-cytokine therapy based on pathophysiology has resulted in significant progress in the treatment of AOSD. Here, we review current knowledge of the pathogenesis, disease progression, currently available biomarkers of disease activity, standard therapeutic agents, utility of biologic agents, future perspectives for treatment and treatment of macrophage activation syndrome. Expert commentary: Accumulated clinical data suggest that chronic disease can be classified into two subsets: dominant systemic disease, and the arthritis subgroup. IL-1 inhibitors may be more efficient for systemic manifestations and IL-6 inhibitor for both joint involvement and systemic manifestations. TNF inhibitors must be reserved for patients with purely chronic articular manifestations. For ideal management of patients, it is very important to measure disease activity accurately during follow up, but no single biomarker has been classified as ideal. New therapeutic agents and composite biomarkers are needed to improve the outcome of patients with AOSD by identifying disease activity properly.

    Sporadic late-onset nemaline myopathy (SLONM) is a rare intractable acquired myopathy characterized by progressive muscle weakness and atrophy, usually with middle to late adult onset. Autologous peripheral blood stem cell transplantation (auto-PBSCT) has been reported to be a promising treatment for SLONM. In this study we performed clinical characterization, muscle histopathological analysis, and muscle power monitoring after auto-PBSCT in a 27-year-old HIV-negative man with monoclonal gammopathy. He showed improved muscle strength after treatment with high-dose melphalan and auto-PBSCT. Considering the recent reports of successful treatment of SLONM, early and correct diagnosis of this condition in association with monoclonal gammopathy is important. SLONM should be added to the list of diseases to consider in the differential diagnosis of progressive muscle weakness with young adult onset. © 2014 Wiley Periodicals, Inc.

    The age-at-onset criterion for separation anxiety disorder was removed in DSM-5, making it timely to examine the epidemiology of separation anxiety disorder as a disorder with onsets spanning the life course, using cross-country data. The sample included 38,993 adults in 18 countries in the World Health Organization (WHO) World Mental Health Surveys. The WHO Composite International Diagnostic Interview was used to assess a range of DSM-IV disorders that included an expanded definition of separation anxiety disorder allowing onsets in adulthood. Analyses focused on prevalence, age at onset, comorbidity, predictors of onset and persistence, and separation anxiety-related role impairment. Lifetime separation anxiety disorder prevalence averaged 4.8% across countries (interquartile range [25th-75th percentiles]=1.4%-6.4%), with 43.1% of lifetime onsets occurring after age 18. Significant time-lagged associations were found between earlier separation anxiety disorder and subsequent onset of internalizing and externalizing DSM-IV disorders and conversely between these disorders and subsequent onset of separation anxiety disorder. Other consistently significant predictors of lifetime separation anxiety disorder included female gender, retrospectively reported childhood adversities, and lifetime traumatic events. These predictors were largely comparable for separation anxiety disorder onsets in childhood, adolescence, and adulthood and across country income groups. Twelve-month separation anxiety disorder prevalence was considerably lower than lifetime prevalence (1.0% of the total sample; interquartile range=0.2%-1.2%). Severe separation anxiety-related 12-month role impairment was significantly more common in the presence (42.4%) than absence (18.3%) of 12-month comorbidity. Separation anxiety disorder is a common and highly comorbid disorder that can have onset across the lifespan. Childhood adversity and lifetime trauma are important antecedents, and adverse effects on

    Adult-onset autoimmune diabetes is a heterogeneous disease that is characterized by a reduced genetic load, a less intensive autoimmune process and a mild metabolic decompensation at onset compared with young-onset type 1 diabetes mellitus (T1DM). The majority of patients with adult-onset autoimmune diabetes do not require insulin treatment for at least 6 months after diagnosis. Such patients are defined as having latent autoimmune diabetes in adults (LADA), which is distinct from classic adult-onset T1DM. The extensive heterogeneity of adult-onset autoimmune diabetes is apparent beyond the distinction between classic adult-onset T1DM and LADA. LADA is characterized by genetic, phenotypic and humoral heterogeneity, encompassing different degrees of insulin resistance and autoimmunity; this heterogeneity is probably a result of different pathological mechanisms, which have implications for treatment. The existence of heterogeneous phenotypes in LADA makes it difficult to establish an a priori treatment algorithm, and therefore, a personalized medicine approach is required. In this Review, we discuss the current understanding and gaps in knowledge regarding the pathophysiology and clinical features of adult-onset autoimmune diabetes and highlight the similarities and differences with classic T1DM and type 2 diabetes mellitus.

    Interleukin 6 (IL6) is an inflammatory cytokine that has been suggested to have an important role in the pathogenesis of asthma. IL6 single-nucleotide polymorphisms (SNPs) have been associated with levels of IL6, and with childhood and prevalent adult asthma. A recent study also suggested that IL6 SNPs associate especially with atopic asthma. However, association of IL6 SNPs with adult-onset asthma has not been studied. In a population-based study of 467 incident adult-onset asthma cases and 613 disease-free controls from South Finland, we analyzed association of 6 tagging SNPs of the IL6 locus with the risk of adult-onset asthma and with atopy. Asthma was clinically diagnosed, and atopy was defined based on Phadiatop test. IL6 SNP rs1800797 associated with the risk of adult-onset asthma in a log additive model, with adjusted odds ratio (aOR) 1.31 (95% confidence interval 1.09-1.57), and especially with the risk of atopic adult-onset asthma when compared with non-atopic controls, aOR 1.46 (95% CI 1.12-1.90). This is the first study to show an association of IL6 with adult-onset asthma, and especially with atopic adult-onset asthma.

    To describe the clinical, laboratory and radiological features, treatment and prognosis of patients with adult onset Still's disease (AOSD). Specific clinical features were retrospectively recorded in 41 patients fulfilling the Yamaguchi criteria. Patients were reviewed in two academic hospitals with a referral area of 700,000-1,000,000 inhabitants. Laboratory tests including haemogram, ferritin, biochemistry and autoimmunity were reviewed. Radiological studies, treatment and ACR functional class were determined. Forty-one patients with AOSD were identified, 25 of whom were female. Mean age at diagnosis: 38.19 years (range 17-68). Feverish polyarthritis was the most common clinical presentation. Acute phase reactants were invariably high in all patients. Serum ferritin levels were elevated in 86% of patients. Anti-cyclic citrullinated peptide antibodies (anti-CCP antibodies) were negative in all patients except one. The course of the disease was monocyclic in 44% of the patients, polycyclic in 26%, and chronic articular in 30%. ACR class was as follows: 29 (72.5%) class I, 7 (17.5%) class II, 2 (5%) class III and 2 (5%) class IV. As for the treatment received, aspirin or NSAIDs controlled the disease in eight patients (19.5%) and high-dose corticosteroids (0.5-1 mg/kg/day) in 32 (78%). Almost half of the patients (49%) required an additional diseasemodifying agent, usually methotrexate. Finally, in seven of them (17%) a biological treatment with TNF-α or specially anti-IL-1 had to be added to control the disease. The clinical and laboratory findings were similar to previous studies. Anti-CCP antibodies were almost always negative. A monocyclic course was associated with a good prognosis. Most of the patients were in ACR functional class I and II. Biological agents were required in 7 patients (17%).

    Few studies have examined outcomes in adults with pediatric-onset morphea. The objective of the present study was to compare clinical outcomes and health-related quality of life (HRQOL) in adults with onset of morphea in childhood to those in patients with adult onset of morphea. Participants in the study were drawn from the Morphea in Adults and Children cohort and included 68 adults with pediatric-onset morphea and 234 patients with adult-onset morphea. Outcome measures included the Localized Scleroderma Cutaneous Assessment Tool (LoSCAT), physical examination findings, and HRQOL questionnaires. Adults with pediatric-onset morphea were younger, had longer disease duration, and were more likely to have the linear subtype of morphea. Patients with pediatric-onset disease were less likely to have active disease. Among patients with active disease, those with pediatric-onset morphea had less disease activity as measured by the LoSCAT. Patients with pediatric-onset disease had higher severity of disease damage when measured by the physician's global assessment of damage, but had similar levels of disease damage when measured by the Localized Scleroderma Skin Damage Index. Patients with pediatric-onset disease had more favorable HRQOL scores for all measures, all of which were statistically significantly different from those in patients with adult-onset morphea. Adults with pediatric-onset morphea differ from patients with adult-onset disease with respect to disease subtype, severity of disease activity and damage, and levels of HRQOL.

    Systemic lupus erythematosus (SLE) affects people in childhood (childhood onset) or in adulthood (adult onset). Observational studies that have previously compared childhood-onset versus adult-onset SLE were often restricted to 1 ethnic group, or to a particular area, with a small sample size of patients. We aimed to systematically compare childhood-onset versus adult-onset SLE through a meta-analysis. Electronic databases were searched for relevant publications comparing childhood-onset with adult-onset SLE. Adverse clinical features were considered as the endpoints. The Newcastle Ottawa Scale (NOS) was used to assess the methodological quality of the studies and RevMan software (version 5.3) was used to carry out this analysis whereby risk ratios (RRs) and 95% confidence intervals (95% CIs) were used as the statistical parameters. A total number of 10,261 participants (1560 participants with childhood-onset SLE and 8701 participants with adult-onset SLE) were enrolled. Results of this analysis showed that compared with childhood-onset SLE, pulmonary involvement was significantly higher with adult-onset SLE (RR: 1.51, 95% CI: 1.18-1.93; P = .001), whereas renal involvement was significantly higher with childhood-onset SLE (RR: 0.65, 95% CI: 0.55-0.77; P = .00001). Raynaud phenomenon and photosensitivity were significantly higher in adult-onset SLE (RR: 1.29, 95% CI: 1.04-1.60; P = .02) and (RR: 1.08, 95% CI: 1.01-1.17; P = .03), respectively. Malar rash significantly favored adult-onset SLE (RR: 0.84, 95% CI: 0.75-0.94; P = .002). Childhood-onset SLE was associated with significantly higher hemolytic anemia, thrombocytopenia, leukocytopenia, and lymphopenia. Seizure and ocular manifestations were significantly higher with childhood-onset SLE (RR: 0.57, 95% CI: 0.47-0.70; P = .00001) and (RR: 0.34, 95% CI: 0.21-0.55; P = .00001), respectively, whereas pleuritis was significantly higher with adult-onset SLE (RR: 1.45, 95% CI: 1

    Full Text Available Prescription drug abuse and dependence is an increasing concern for older adults. This article describes issues specific to older adults with late onset abuse or dependence on prescription sedatives and/or opiates.The older adult with late onset should not be viewed as having the same issues as individuals who have a life pat- tern of drug and alcohol abuse/dependence.A chart review of older adults in a treatment program contrasts late onset prescription dependence clients (n=12 and early onset addiction clients (n=104 and outlines differences and similarities between the two samples. Social workers need to understand the specific and changing needs of older adults as they relate to assessment and treatment of drug abuse and dependence.

    Age of onset for Huntington's disease (HD) varies inversely with the length of the disease-causing CAG repeat expansion in the HD gene. A simple exponential regression model yielded adjusted R-squared values of 0.728 in a large set of Venezuelan kindreds and 0.642 in a North American, European, and Australian sample (the HD MAPS cohort). We present evidence that a two-segment exponential regression curve provides a significantly better fit than the simple exponential regression. A plot of natural log-transformed age of onset against CAG repeat length reveals this segmental relationship. This two-segment exponential regression on age of onset data increases the adjusted R-squared values by 0.012 in the Venezuelan kindreds and by 0.035 in the HD MAPS cohort. Although the amount of additional variance explained by the segmental regression approach is modest, the two slopes of the two-segment regression are significantly different from each other in both the Venezuelan kindreds [F(2, 439) = 11.13, P= 2 x 10(-5)] and in the HD MAPS cohort [F(2, 688) = 38.27, P= 2 x 10(-16)]. In both populations, the influence of each CAG repeat on age of onset appears to be stronger in the adult-onset range of CAG repeats than in the juvenile-onset range.

    Abstract The diagnosis of adult-onset Still's disease (AOSD) can be very difficult. There are no specific tests available, and diagnosis is usually based on a symptom complex and the well-described typical evanescent rash seen in the majority of patients. However, in recent years, other atypical cutaneous manifestations of AOSD have been reported. These atypical skin eruptions often present in addition to the typical evanescent rash but may also be the only skin manifestation, resulting in delayed diagnosis because of under-recognition. In this study, we present 3 new cases of AOSD with atypical cutaneous manifestations diagnosed during a 30-year period in our department and review 78 additional cases previously reported (PubMed 1990–2016). These 81 patients form the basis of the present analysis. The overall prevalence of atypical cutaneous manifestations in our AOSD population was 14%. These manifestations may appear at any time over the course of the disease, and usually occur in patients who have persistent and severe disease, with a considerable frequency of clinical complications (23%), including serositis, myopericarditis, lung involvement, abdominal pain, neurologic involvement, and reactive hemophagocytic syndrome. The most representative and frequent lesion among the nonclassical skin rashes is the development of persistent pruritic papules and/or plaques. Interestingly, these lesions show a distinctive histological pattern. Other, less frequently observed lesions include urticaria and urticaria-like eruptions, generalized or widespread non-pruritic persistent erythema, vesiculopustular eruptions, a widespread peau d’orange appearance of the skin, and edema of the eyelids mimicking dermatomyositis without any accompanying skin lesion. The great majority of these patients required medium or high doses of glucocorticoids (including intravenous methylprednisolone pulse therapy in some cases) and, in nearly 40%, a more potent or maintenance immunotherapy

    Full Text Available Abeta peptide accumulation is thought to be the primary event in the pathogenesis of Alzheimer's disease (AD, with downstream neurotoxic effects including the hyperphosphorylation of tau protein. Glycogen synthase kinase-3 (GSK-3 is increasingly implicated as playing a pivotal role in this amyloid cascade. We have developed an adult-onset Drosophila model of AD, using an inducible gene expression system to express Arctic mutant Abeta42 specifically in adult neurons, to avoid developmental effects. Abeta42 accumulated with age in these flies and they displayed increased mortality together with progressive neuronal dysfunction, but in the apparent absence of neuronal loss. This fly model can thus be used to examine the role of events during adulthood and early AD aetiology. Expression of Abeta42 in adult neurons increased GSK-3 activity, and inhibition of GSK-3 (either genetically or pharmacologically by lithium treatment rescued Abeta42 toxicity. Abeta42 pathogenesis was also reduced by removal of endogenous fly tau; but, within the limits of detection of available methods, tau phosphorylation did not appear to be altered in flies expressing Abeta42. The GSK-3-mediated effects on Abeta42 toxicity appear to be at least in part mediated by tau-independent mechanisms, because the protective effect of lithium alone was greater than that of the removal of tau alone. Finally, Abeta42 levels were reduced upon GSK-3 inhibition, pointing to a direct role of GSK-3 in the regulation of Abeta42 peptide level, in the absence of APP processing. Our study points to the need both to identify the mechanisms by which GSK-3 modulates Abeta42 levels in the fly and to determine if similar mechanisms are present in mammals, and it supports the potential therapeutic use of GSK-3 inhibitors in AD.

    2012-02-01

    Adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance; patients with sporadic adult-onset primary torsion dystonia are much more prevalent than familial. The temporal discrimination threshold is the shortest time interval at which two stimuli are detected to be asynchronous and has been shown to be abnormal in adult-onset primary torsion dystonia. The aim was to determine the frequency of abnormal temporal discrimination thresholds in patients with sporadic adult-onset primary torsion dystonia and their first-degree relatives. We hypothesized that abnormal temporal discrimination thresholds in first relatives would be compatible with an autosomal dominant endophenotype. Temporal discrimination thresholds were examined in 61 control subjects (39 subjects <50 years of age; 22 subjects >50 years of age), 32 patients with sporadic adult-onset primary torsion dystonia (cervical dystonia n = 30, spasmodic dysphonia n = 1 and Meige\\'s syndrome n = 1) and 73 unaffected first-degree relatives (36 siblings, 36 offspring and one parent) using visual and tactile stimuli. Z-scores were calculated for all subjects; a Z > 2.5 was considered abnormal. Abnormal temporal discrimination thresholds were found in 1\\/61 (2%) control subjects, 27\\/32 (84%) patients with adult-onset primary torsion dystonia and 32\\/73 (44%) unaffected relatives [siblings (20\\/36; 56%), offspring (11\\/36; 31%) and one parent]. When two or more relatives were tested in any one family, 22 of 24 families had at least one first-degree relative with an abnormal temporal discrimination threshold. The frequency of abnormal temporal discrimination thresholds in first-degree relatives of patients with sporadic adult-onset primary torsion dystonia is compatible with an autosomal dominant disorder and supports the hypothesis that apparently sporadic adult-onset primary torsion dystonia is genetic in origin.

    Proper positioning of neurons is fundamental for brain functions. However, little is known on how adult-born neurons generated in the hilar side of hippocampal dentate gyrus migrate into the granular cell layer. Because class 3 Semaphorins (Sema3) are involved in dendritic growth of these newborn neurons, we examined whether they are essential for cell positioning. We disrupted Sema3 signaling by silencing neuropilin 1 (NRP1) or 2 (NRP2), the main receptors for Sema3A and Sema3F, in neural progenitors of adult mouse dentate gyrus. Silencing of NRP2, but not NRP1, affected cell positioning of adult newborn neurons. Glycogen synthase kinase-3β (GSK3β) knockdown phenocopied this NRP2 silencing-mediated cell positioning defect, but did not affect dendritic growth. Furthermore, GSK3β is activated upon stimulation with Sema3F, and GSK3β overexpression rescued the cell positioning phenotypes seen in NRP2-deficient neurons. These results point to a new role for NRP2 in the positioning of neurons during adult hippocampal neurogenesis, acting via the GSK3β signaling pathway. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available Abstract Background Cyclic Vomiting Syndrome (CVS is a well-recognized functional gastrointestinal disorder in children but its presentation is poorly understood in adults. Genetic differences in pediatric-onset (presentation before age 18 and adult-onset CVS have been reported recently but their clinical features and possible differences in response to therapy have not been well studied. Methods This was a retrospective review of 101 CVS patients seen at the Medical College of Wisconsin between 2006 and 2008. Rome III criteria were utilized to make the diagnosis of CVS. Results Our study population comprised of 29(29% pediatric-onset and 72 (71% adult-onset CVS patients. Pediatric-onset CVS patients were more likely to be female (86% vs. 57%, p = 0.005 and had a higher prevalence of CVS plus (CVS + neurocognitive disorders as compared to adult-onset CVS patients (14% vs. 3%, p = 0.05. There was a longer delay in diagnosis (10 ± 7 years in the pediatric-onset group when compared to (5 ± 7 years adult-onset CVS group (p = 0.001. Chronic opiate use was less frequent in the pediatric-onset group compared to adult-onset patients (0% vs. 23%, p = 0.004. Aside from these differences, the two groups were similar with regards to their clinical features and the time of onset of symptoms did not predict response to standard treatment. The majority of patients (86% responded to treatment with tricyclic antidepressants, anticonvulsants (topiramate, coenzyme Q-10, and L-carnitine. Non-response to therapy was associated with coalescence of symptoms, chronic opiate use and more severe disease as characterized by longer episodes, greater number of emergency department visits in the year prior to presentation, presence of disability and non-compliance on univariate analysis. On multivariate analysis, only compliance to therapy was associated with a response. (88% vs. 38%, Odds Ratio, OR 9.6; 95% Confidence Interval [CI], 1.18-77.05. Conclusion Despite reported

    Hallervorden-Spatz disease is a rare neurological disorder characterized by pyramidal and extrapyramidal manifestations, dysarthria and dementia. Its onset is usually in childhood and most patients have a fatal outcome in few years. A high percentage of cases are hereditary with a recessive autosomal pattern. In the majority of the patients reported, a mutation of the gene that encodes the pantothenate kinase (PANK2) located in the 20p13-p12.3 chromosome that causes iron storage in the basal ganglia of the brain has been found. Its diagnosis is based on clinical symptoms as well as specific MRI imaging findings. The most common psychiatric features are cognitive impairment as well as depressive symptoms. There are few documented cases with psychotic disorders. We present the case of a patient with late onset Hallervorden-Spatz disease and psychotic symptoms that preceded the development of neurological manifestations. The pathophysiology and the treatment of psychotic symptomatology are presented and discussed. Key words: Psicosis, Hallervorden-Spatz, late onset, Basal ganglia.

    Brain glycogen localized in astrocytes, a critical energy source for neurons, decreases during prolonged exhaustive exercise with hypoglycaemia. However, it is uncertain whether exhaustive exercise induces glycogen supercompensation in the brain as in skeletal muscle. To explore this question, we exercised adult male rats to exhaustion at moderate intensity (20 m min(-1)) by treadmill, and quantified glycogen levels in several brain loci and skeletal muscles using a high-power (10 kW) microwave irradiation method as a gold standard. Skeletal muscle glycogen was depleted by 82-90% with exhaustive exercise, and supercompensated by 43-46% at 24 h after exercise. Brain glycogen levels decreased by 50-64% with exhaustive exercise, and supercompensated by 29-63% (whole brain 46%, cortex 60%, hippocampus 33%, hypothalamus 29%, cerebellum 63% and brainstem 49%) at 6 h after exercise. The brain glycogen supercompensation rates after exercise positively correlated with their decrease rates during exercise. We also observed that cortical and hippocampal glycogen supercompensation were sustained until 24 h after exercise (long-lasting supercompensation), and their basal glycogen levels increased with 4 weeks of exercise training (60 min day(-1) at 20 m min(-1)). These results support the hypothesis that, like the effect in skeletal muscles, glycogen supercompensation also occurs in the brain following exhaustive exercise, and the extent of supercompensation is dependent on that of glycogen decrease during exercise across brain regions. However, supercompensation in the brain preceded that of skeletal muscles. Further, the long-lasting supercompensation of the cortex and hippocampus is probably a prerequisite for their training adaptation (increased basal levels), probably to meet the increased energy demands of the brain in exercising animals.

    We present genetically identical twin patients who experienced late-onset migraine with visual and somatosensory auras and later developed hemiplegic migraines associated with severe cortical oedema and enhancement. Both positron emission tomography and electroencephalography showed an increase in activity contralateral to the hemiplegic side. Brain biopsy during the attack showed reactive astrogliosis and microgliosis. Mutations in CACNA1A, ATP1A2, SLC1A3 and NOTCH3 were ruled out by sequencing. This report shows the clinical and genetic evaluation of a severe form of familial hemiplegic migraine as well as the evolution of the imaging changes.

    Minimal change disease (MCD) is a well-known benign primary glomerulonephritis because of its distinct rare tendency to progress to end-stage renal disease. However, factors associated with relapse in adults are not well known. We aimed to identify predictors of relapse in adult-onset MCD patients.A retrospective cohort of 195 patients with adult-onset primary MCD with nephritic syndrome and disease onset between 1979 and 2013 was followed up for >12 months. The number of relapses was counted and predictors of relapse were analyzed.A total of 195 patients were included. Median age at diagnosis was 38 years (IQR, 23-53 years) and 113 (57.9%) were men. During 81 months (IQR, 44-153 months) of follow-up, 92% of patients achieved remission after initial treatment. However, only 60 (32.8%) did not experience a relapse and 11 patients failed to remit. Among the remaining 124 patients, 65 experienced a relapse once or twice and 59 experienced a relapse more than twice. Younger onset age, increased severity of nephrotic features such as lower serum albumin levels and higher cholesterol level were associated with relapse. Interestingly, the grade of mesangial proliferation was lower in patients who experienced a relapse. Initial combined treatment with corticosteroids (CS) and cyclophosphamide reduced the number of relapses. In addition, patients with shorter treatment duration tended to experience relapse more often. Multivariate analysis showed that younger onset age, combined mesangial proliferation, initial treatment regimen, and treatment duration were independent risk factors for relapse. Progression to end-stage renal disease was developed in only a patient.In conclusion, more than two-thirds of adult-onset nephrotic MCD patients experienced relapse, although their renal progression was rare. Younger onset age, CS without cyclophosphamide treatment, and shorter treatment duration were independent risk factors for relapse in adult-onset MCD patients.

    Niemann-Pick disease type C (NP-C) is an inherited sphingolipidosis characterized by progressive neurological deterioration and early mortality. The symptomatology and disease progression of NP-C are markedly affected by the age at onset of neurological manifestations, and categorization into early-infantile, late-infantile, juvenile, adolescent/adult neurological onset forms can aid evaluation of disease course and responses to therapy. Here, we review current information on the detection, diagnosis, monitoring and treatment of NP-C, with a focus on the adolescent/adult-onset form. A recent analysis indicated that the combined incidence of NP-C related to NPC1 gene mutations (NPC1) and NP-C related to NPC2 gene mutations (NPC2) is approximately 1 case in every 89 000 live births. In particular, late-onset phenotypes might well provide a greater contribution to the overall incidence than has previously been reported. Some neuropathological features in NP-C are held in common with other advanced age-onset diseases such as Alzheimer's disease. Visceral symptoms such as splenomegaly are frequently asymptomatic in patients with adolescent/adult-onset NP-C, and are only occasionally detected during routine ultrasound assessments. In contrast, most patients with adolescent/adult-onset exhibit some degree of slowly progressive, non-disease-specific movement disorders (e.g. cerebellar ataxia), and/or more pathognomonic neurological signs such as vertical supranuclear gaze palsy. An increasing number of adolescent/adult-onset cases have been reported following initial recognition of cognitive impairment and/or psychiatric signs. The recent development and implementation of new clinical screening tools (e.g. the NP-C suspicion index) and biomarkers (e.g. plasma oxysterols) should help identify patients who warrant further investigation and possible treatment.

    Adult-onset hearing loss is insidious and typically diagnosed and managed several years after onset. Often, this is after the loss having led to multiple negative consequences including effects on employment, depressive symptoms, and increased risk of mortality. In contrast, the use of hearing aids is associated with reduced depression, longer life expectancy, and retention in the workplace. Despite this, several studies indicate high levels of unmet need for hearing health services in older ...

    Although neuronal studies have shown that audiovisual integration is regulated by temporal factors, there is still little knowledge about the impact of temporal factors on audiovisual integration in older adults. To clarify how stimulus onset asynchrony (SOA) between auditory and visual stimuli modulates age-related audiovisual integration, 20 younger adults (21-24 years) and 20 older adults (61-80 years) were instructed to perform an auditory or visual stimuli discrimination experiment. The results showed that in younger adults, audiovisual integration was altered from an enhancement (AV, A ± 50 V) to a depression (A ± 150 V). In older adults, the alterative pattern was similar to that for younger adults with the expansion of SOA; however, older adults showed significantly delayed onset for the time-window-of-integration and peak latency in all conditions, which further demonstrated that audiovisual integration was delayed more severely with the expansion of SOA, especially in the peak latency for V-preceded-A conditions in older adults. Our study suggested that audiovisual facilitative integration occurs only within a certain SOA range (e.g., -50 to 50 ms) in both younger and older adults. Moreover, our results confirm that the response for older adults was slowed and provided empirical evidence that integration ability is much more sensitive to the temporal alignment of audiovisual stimuli in older adults.

  1. Personality traits among ADHD adults: implications of late-onset and subthreshold diagnoses.

    Diagnosing attention deficit hyperactivity disorder (ADHD) in adults is difficult when diagnosticians cannot establish onset prior to the DSM-IV criterion of age 7 or if the number of symptoms does not achieve the DSM threshold for diagnosis. Previous work has assessed the validity of such diagnoses based on psychiatric co-morbidity, family history and neuropsychological functions but none of these studies have used personality as a validation criterion. We compared four groups of adults: (1) full ADHD subjects who met all DSM-IV criteria for childhood-onset ADHD; (2) late-onset subjects who met all criteria except the age at onset criterion, (3) subthreshold subjects who did not meet full symptom criteria and (4) non-ADHD subjects who did not meet any of the above criteria. Diagnoses were made by using the Structured Clinical Interview for DSM-IV (SCID) and the Temperament and Character Inventory (TCI) was used to assess personality traits. We found that full ADHD and late-onset ADHD showed similar personality profiles with significant deviations on all TCI scales except reward dependence and self-transcendence. By contrast, subthreshold cases only showed deviations on novelty seeking and self-directiveness. These data call into question the stringent age of onset of ADHD symptom criteria for adults when making retrospective diagnoses of ADHD. Subthreshold ADHD seems to be a milder form of the disorder that is consistent with dimensional views of the disorder.

    Although the estimated contribution of genetic factors is high in bipolar disorder, environmental factors may also play a role. This Swedish register-based cohort study of men examined if physical and psychological characteristics in late adolescence, including factors previously linked with bipolar disorder (body mass index, asthma and allergy), are associated with subsequent bipolar disorder in adulthood. Unipolar depression and anxiety are analysed as additional outcomes to identify bipolar disorder-specific associations. A total of 213,693 men born between 1952 and 1956, who participated in compulsory military conscription assessments in late adolescence were followed up to 2009, excluding men with any psychiatric diagnoses at baseline. Cox regression estimated risk of bipolar disorder, depression and anxiety in adulthood associated with body mass index, asthma, allergy, muscular strength stress resilience and cognitive function in adolescence. BMI, asthma and allergy were not associated with bipolar disorder. Higher grip strength, cognitive function and stress resilience were associated with a reduced risk of bipolar disorder and the other disease outcomes. The sample consisted only of men; even though the characteristics in adolescence pre-dated disease onset, they may have been the consequence of prodromal disease. Associations with body mass index and asthma found by previous studies may be consequences of bipolar disorder or its treatment rather than risk factors. Inverse associations with all the outcome diagnoses for stress resilience, muscular strength and cognitive function may reflect general risks for these psychiatric disorders or intermediary factors.

    A number of small cross sectional studies have demonstrated that hypovitaminosis D (represented by low 25 hydroxyvitamin D (25OHD) levels) is associated with orthostatic hypotension (OH). We investigated if hypovitaminosis D is associated with the onset of OH in older adults over a follow-up of 4.4 years. 25OHD was categorized using sex-specific quartiles; OH was defined as a drop of ≤20 mm Hg in systolic or ≤10 mm Hg in diastolic blood pressure hypovitaminosis D predicts the onset of OH in older adults, particularly in women.

    Adult-onset muscular dystrophy is an inherited myopathy characterized by a variable degree of progressive muscle weakness and degeneration. Although not usually fatal, significant muscle weakness results in an up-regulation of acetylcholine receptors on the less responsive postjunctional muscles. The resulting profound potassium release when these receptors are stimulated by the depolarizing muscle relaxant succinylcholine can result in potentially fatal cardiac arrhythmias. We report a case of electroconvulsive therapy safely administered in a 61-year-old man with adult-onset muscular dystrophy requiring muscle relaxation with rocuronium.

    Adult-onset Still's disease is a rare disorder with potentially severe clinical features, including cardiac involvement. This systemic inflammatory disease of unknown origin should be considered in the differential diagnosis of pericarditis, with or without pericardial effusion. Cardiac tamponade is a very rare sequela that requires an invasive approach, such as percutaneous or surgical pericardial drainage, in addition to the usual conservative therapy. The authors describe a case of adult-onset Still's disease rendered more difficult by pericarditis and cardiac tamponade, and they briefly review the literature on this entity.

Here we present a case of 55-year-old woman with a history of a few months fever, progressing weakness and salmon-coloured, macular skin rash. The differential diagnosis included neoplasmatic conditions, infections and connective tissue disorders. Finally adult onset Still's disease was suspected. Glucocorticosteroid treatment was induced. During the therapy a central nervous system infection occurred, which was fatal for the patient. The presented clinical case shows that among many causes of fever of unknown origin, adult onset Still's disease should be taken into account.

    Full Text Available Xanthelasmoid or pseudoxanthomatous mastocytosis is an extremely rare variant of diffuse cutaneous mastocytosis. Herein, we describe an adult male with cutaneous mastocytosis showing multiple widespread yellowish ovoid papules like eruptive xanthoma. A 60-year-old male visited our outpatient clinic with a 1-year history of generalized yellowish, ovoid, and skin color papular eruption located on the trunk, groin, extremities, with the modest pruritus. Vital signs were stable, and Darier′s sign was negative. No other subjective and objective signs were detected during the examination. No abnormality was detected in his diagnostic laboratory tests. Skin biopsy was taken, and histopathologic examination revealed proliferation of mast cells with ovoid and spindle nuclei with distinct cytoplasm borders around the capillaries, which was compatible with mastocytosis. Antihistamine was prescribed for pruritus control which was successful, but eruptions were persistent, and even 1-year phototherapy was not useful.

  19. Temporal discrimination threshold: VBM evidence for an endophenotype in adult onset primary torsion dystonia.

    LENUS (Irish Health Repository)

    Bradley, D

    2012-02-01

    Familial adult-onset primary torsion dystonia is an autosomal dominant disorder with markedly reduced penetrance. Most adult-onset primary torsion dystonia patients are sporadic cases. Disordered sensory processing is found in adult-onset primary torsion dystonia patients; if also present in their unaffected relatives this abnormality may indicate non-manifesting gene carriage. Temporal discrimination thresholds (TDTs) are abnormal in adult-onset primary torsion dystonia, but their utility as a possible endophenotype has not been examined. We examined 35 adult-onset primary torsion dystonia patients (17 familial, 18 sporadic), 42 unaffected first-degree relatives of both familial and sporadic adult-onset primary torsion dystonia patients, 32 unaffected second-degree relatives of familial adult-onset primary torsion dystonia (AOPTD) patients and 43 control subjects. TDT was measured using visual and tactile stimuli. In 33 unaffected relatives, voxel-based morphometry was used to compare putaminal volumes between relatives with abnormal and normal TDTs. The mean TDT in 26 control subjects under 50 years of age was 22.85 ms (SD 8.00; 95% CI: 19.62-26.09 ms). The mean TDT in 17 control subjects over 50 years was 30.87 ms (SD 5.48; 95% CI: 28.05-33.69 ms). The upper limit of normal, defined as control mean + 2.5 SD, was 42.86 ms in the under 50 years group and 44.58 ms in the over 50 years group. Thirty out of thirty-five (86%) AOPTD patients had abnormal TDTs with similar frequencies of abnormalities in sporadic and familial patients. Twenty-two out of forty-two (52%) unaffected first-degree relatives had abnormal TDTs with similar frequencies in relatives of sporadic and familial AOPTD patients. Abnormal TDTs were found in 16\\/32 (50%) of second-degree relatives. Voxel-based morphometry analysis comparing 13 unaffected relatives with abnormal TDTs and 20 with normal TDTs demonstrated a bilateral increase in putaminal grey matter in unaffected relatives with abnormal

  20. Suppurative necrotizing granulomatous lymphadenitis in adult-onset Still’s disease: a case report

    Directory of Open Access Journals (Sweden)

    Assimakopoulos Stelios F

    2012-10-01

    Full Text Available Abstract Introduction Lymphadenopathy is found in about 65% of patients with adult-onset Still’s disease and is histologically characterized by an intense, paracortical immunoblastic hyperplasia. Adult-onset Still’s disease has not been previously described as an etiology of suppurative necrotizing granulomatous lymphadenitis. Case presentation We describe a 27-year-old Greek man who manifested prolonged fever, abdominal pain, increased inflammatory markers, episodic skin rash and mesenteric lymphadenopathy histologically characterized by necrotizing granulomatous adenitis with central suppuration. Disease flares were characterized by systemic inflammatory response syndrome with immediate clinico-laboratory response to corticosteroids but the patient required prolonged administration of methylprednisolone at a dose of above 12mg/day for disease control. After an extensive diagnostic work-up, which ruled out any infectious, malignant, rheumatic or autoinflammatory disease the patient was diagnosed as having adult-onset Still’s disease. The patient is currently treated with 4mg of methylprednisolone, 100mg of anakinra daily and methotrexate 7.5mg for two consecutive days per week and exerts full disease remission for six months. Conclusion To the best of our knowledge this is the first report of suppurative necrotizing granulomatous lymphadenitis attributed to adult-onset Still’s disease. This case indicates that the finding of a suppurative necrotizing granulomatous lymphadenitis should not deter the consideration of adult-onset Still’s disease as a potential diagnosis in a compatible clinical context; however, the exclusion of other diagnoses is a prerequisite.

    Glaucoma is the third-leading cause of blindness in the world, affecting >13.5 million people. Adult-on-set primary open-angle glaucoma (POAG) is the most common form of glaucoma in the United States. We present a family in which adult-onset POAG is inherited as an autosomal dominant trait. Twelve affected family members were identified from 44 at-risk individuals. The disease-causing gene was mapped to chromosome 3q21-24, with analysis of recombinant haplotypes suggesting a total inclusion region of 11.1 cM between markers D3S3637 and D3S1744. This is the first report of mapping of an adult-onset POAG gene to chromosome 3q, gene symbol GLC1C. 57 refs., 3 figs., 3 tabs.

    Myasthenia gravis (MG) is an autoimmune neuromuscular junction disorder which is characterized by fluctuating muscle fatigue. However, the association of MG with nemaline myopathy is rarely reported. Here we report a case of MG coexisting with adult-onset nemaline myopathy. A 55-year-old man endured fluctuating muscle weakness with positive acetylcholine receptor and titin antibodies. After the patient was administrated cholinergic drugs and immunosuppression, the muscle weakness of the patient had mildly been alleviated. Electromyography showed a progressive decrement in the amplitude of muscle action potential at low frequency. Muscle biopsy showed numerous nemalines in the muscle fibers. This is the first reported case of nemalines present in the muscle fibers of adult patient with MG. The pathogenesis of nemaline may be related to titin antibody in adult-onset nemaline myopathy with MG.

    Full Text Available Adult-onset hemophagocytic lymphohistiocytosis (HLH has features that are distinct from that of HLH in pediatric patients. The clinical records at the Japanese Red Cross Kumamoto Hospital were reviewed. We retrospectively analyzed 34 patients who fulfilled the diagnostic criteria of HLH-2004. The median age of patients was 60.0 (range 15-86. Underlying diseases were diagnosed in 17 patients. They consisted of malignant lymphoma (n=3, other neoplastic disease (n=3, viral infection (n=4, collagen vascular disease (n=3, Kikuchi’s disease (n=3 and drug (n=1. Underlying diseases were not diagnosed in 17 patients despite examination. The treatments were steroids (n=18, dexamethasone + cyclosporine A (CSA + etoposide (n=4, multidrug chemotherapy (n=2, steroids and CSA (n=3. Eleven patients died during observation. In a multivariate analysis, the significant predictor for death was age at onset (hazard ratio, 1.22; 95%CI, 1.02-1.44; P=0.027. Autopsy was performed in 4 cases, but the underlying disease remained unknown in 3 of those cases. Adult-onset HLH has high diversity and various outcomes. The mechanism of adult-onset HLH is not fully understood and further research is required.

  4. Adult-Onset Type 1 Diabetes and Pregnancy: Three Case Reports

    Full Text Available From 5% to 10% of diabetic patients have type 1 diabetes. Here we describe three cases of adult-onset type 1 diabetes in pregnancy treated at our clinic between 2009 and 2012. Two patients came for specialist examination during pregnancy, the third after pregnancy. These women had no prior overt diabetes and shared certain characteristics, that is, no family diabetes history, age over 35, normal prepregnancy BMI, need for insulin therapy as of the early weeks of pregnancy, and high-titer anti-GAD antibody positivity. The patients had persistent diabetes after delivery, suggesting that they developed adult-onset type 1 diabetes during pregnancy. About 10% of GDM patients become pancreatic autoantibody positive and the risk of developing overt diabetes is higher when two or more autoantibodies are present (particularly GAD and ICA. GAD-Ab shows the highest sensitivity for type 1 diabetes prediction. We need to bear in mind that older patients might conceivably develop an adult-onset type 1 diabetes during or after pregnancy. So we suggest that women with GDM showing the described clinical features shall be preferably tested for autoimmunity. Pregnant patients at risk of type 1 diabetes should be identified to avoid the maternal and fetal complications and the acute onset of diabetes afterwards.

    Cardiopulmonary manifestations of adult-onset Still's disease (AOSD) include pericarditis, pleural effusion, transient pulmonary infiltrates, pulmonary interstitial disease and myocarditis. Serositis are common but pneumonitis and myocarditis are not and bring elevated risk of mortality. They may manifest on disease onset or flares. Previously reported cases were treated with high-dose glucocorticoids and immunosupressants and, when refractory, intravenous immunoglobulin (IVIG). We report an AOSD patient whose flare presented with severe pleupneumonitis and myopericarditis and, following nonresponse to a methylprednisolone pulse, high dose of prednisone and cyclosporine A, recovered after a 2-day 1g/kg/day IVIG infusion.

    The primary purpose of this paper is to undertake foundational research in the area of career readiness, work personality and age of onset with young adult central nervous system (CNS) survivors. Participants for this study consisted of 43 individuals whose age range from 18 to 30 (M = 21.64, SD = 3.46), an average age of brain tumor onset of 9.50 years (SD = 4.73) and average years off of treatment of 7.25 years (SD = 5.80). Packets were distributed to survivors who were participating in a psychosocial cancer treatment program. Participants completed multiple career instruments and a demographic form. Differences between groups and among the variables were examined and size effect sizes were analyzed. Young adult CNS survivors had significantly lower levels of work personality and career readiness when compared to young adult non-cancer survivors with CNS cancer with those between the ages of 6 and 12 reported significantly lower levels when compared to individuals diagnosed before age 6 and after the age of 13. Young adult CNS survivors at an increased risk for having lower levels of work personality and career readiness then a norm group comparison. Age of onset (between 6 and 12) may be at significant risk factor for developing poor or dysfunctional work and career behaviors. • Young adults with central nervous system (CNS) cancer are at particular risk for experiencing difficulties related to career and employment. • Work personality and career readiness are two constructs that have been found to be related to one's ability to meet the demands of work. • Young adult CNS cancer survivors have lower levels of work personality and career readiness. • Individuals diagnosed between the ages of 6 and 12 may be at particular risk and may need specific vocational rehabilitation interventions. • The results of this study point to the need for comprehensive career and vocational services for young adult CNS cancer survivors.

    OBJECTIVE Adult-onset hydrocephalus is not commonly discussed in the literature, especially regarding its demographic distribution. In contrast to pediatric hydrocephalus, which is related to a primary CSF pathway defect, its development in adults is often secondary to other pathologies. In this study, the authors investigated the epidemiology of adult-onset hydrocephalus as it pertains to different etiologies and in reference to age, sex, and race distributions. METHODS The authors retrospectively reviewed the clinical notes of 2001 patients with adult-onset hydrocephalus who presented to Louisiana State University Health Sciences Center within a 25-year span. Significant differences between the groups were analyzed by a chi-square test; p hydrocephalus in this population was 77 ± 30 per year, with a significant increase in incidence in the past decade (55 ± 3 [1990-2003] vs 102 ± 6 [2004-2015]; p Hydrocephalus in a majority of the patients had a vascular etiology (45.5%) or was a result of a tumor (30.2%). The incidence of hydrocephalus in different age groups varied according to various pathologies. The incidence was significantly higher in males with normal-pressure hydrocephalus (p = 0.03) or head injury (p = 0.01) and higher in females with pseudotumor cerebri (p hydrocephalus was significantly higher in Caucasian patients (p = 0.0002) than in those of any other race. CONCLUSIONS Knowledge of the demographic variations in adult-onset hydrocephalus is helpful in achieving better risk stratification and better managing the disease in patients. For general applicability, these results should be validated in a large-scale meta-analysis based on a national population database.

    2015-03-01

    This paper aims to examine the relationship between obesity and onset of depression among U.S. middle-aged and older adults. Data came from 1994 to 2010 waves of the Health and Retirement Study. Study sample consisted of 6514 community-dwelling adults born between 1931 and 1941 who were free of clinically relevant depressive symptoms in 1994. Body mass index (BMI) was calculated from self-reported height/weight. Body weight status was classified into normal weight (18.5kg/m(2)≤BMIobesity (BMI≥30kg/m(2)). A score of ≥3 on the 8-item Center for Epidemiologic Studies Depression Scale was used to define clinically relevant depressive symptoms. Kaplan-Meier estimator and time-dependent Cox proportional hazards model were performed to examine the association between body weight status and onset of clinically relevant depressive symptoms. Unhealthy body weight was associated future onset of depression. Compared with their normal weight counterparts, overweight and obese participants were 13% (hazard ratio [HR]=1.13, 95% confidence interval [CI]=1.04-1.23) and 9% (HR=1.09, 95% CI=1.01-1.18) more likely to have onset of clinically relevant depressive symptoms during the 16years of follow-up, respectively. The relationship between obesity and depression onset appeared stronger among females and non-Hispanic whites than their male and racial/ethnic minority counterparts. Health care providers should be aware of the potential risk for depression among obese older adults. Copyright © 2014 Elsevier Inc. All rights reserved.

    2015-01-01

    Adult-onset Still's disease is a rare disorder, which creates difficulties in making a proper diagnosis. Ambiguous symptoms and results of auxiliary tests, lack of unequivocal diagnostic tests and the need to exclude other causes of the disease are major problems in clinical practice. A case of a 22-year-old woman with dominated recurrent fever, significantly elevated inflammation markers and arthritis is presented. Based on clinical signs after exclusion of infection, hematological and other reasons, the patient was diagnosed with adult-onset Still's disease. Standard treatment, with high doses of glucocorticoids and a disease-modifying drug, was applied, without the anticipated effects. The diagnostic tests were conducted again due to the lack of clinical improvement, increase of inflammatory markers and unusual response to treatment. A new symptom of significance, i.e. mediastinal lymphadenopathy, was found. After the histopathological examination of lymph nodes, Hodgkin's disease was diagnosed and targeted therapy for hematological malignancy was applied.

The Seinäjoki Adult Asthma Study is a 12-year follow-up study of patients with new-onset adult asthma. K-means cluster analysis was performed by using variables from baseline and follow-up visits on 171 patients to identify phenotypes. Five clusters were identified. Patients in cluster 1 (n = 38) were predominantly nonatopic males with moderate smoking history at baseline. At follow-up, 40% of these patients had developed persistent obstruction but the number of patients with uncontrolled asthma (5%) and rhinitis (10%) was the lowest. Cluster 2 (n = 19) was characterized by older men with heavy smoking history, poor lung function, and persistent obstruction at baseline. At follow-up, these patients were mostly uncontrolled (84%) despite daily use of inhaled corticosteroid (ICS) with add-on therapy. Cluster 3 (n = 50) consisted mostly of nonsmoking females with good lung function at diagnosis/follow-up and well-controlled/partially controlled asthma at follow-up. Cluster 4 (n = 25) had obese and symptomatic patients at baseline/follow-up. At follow-up, these patients had several comorbidities (40% psychiatric disease) and were treated daily with ICS and add-on therapy. Patients in cluster 5 (n = 39) were mostly atopic and had the earliest onset of asthma, the highest blood eosinophils, and FEV1 reversibility at diagnosis. At follow-up, these patients used the lowest ICS dose but 56% were well controlled. Results can be used to predict outcomes of patients with adult-onset asthma and to aid in development of personalized therapy (NCT02733016 at ClinicalTrials.gov). Copyright © 2017 The Authors.

    Full Text Available Environmental compounds can promote epigenetic transgenerational inheritance of adult-onset disease in subsequent generations following ancestral exposure during fetal gonadal sex determination. The current study examined the ability of dioxin (2,3,7,8-tetrachlorodibenzo[p]dioxin, TCDD to promote epigenetic transgenerational inheritance of disease and DNA methylation epimutations in sperm. Gestating F0 generation females were exposed to dioxin during fetal day 8 to 14 and adult-onset disease was evaluated in F1 and F3 generation rats. The incidences of total disease and multiple disease increased in F1 and F3 generations. Prostate disease, ovarian primordial follicle loss and polycystic ovary disease were increased in F1 generation dioxin lineage. Kidney disease in males, pubertal abnormalities in females, ovarian primordial follicle loss and polycystic ovary disease were increased in F3 generation dioxin lineage animals. Analysis of the F3 generation sperm epigenome identified 50 differentially DNA methylated regions (DMR in gene promoters. These DMR provide potential epigenetic biomarkers for transgenerational disease and ancestral environmental exposures. Observations demonstrate dioxin exposure of a gestating female promotes epigenetic transgenerational inheritance of adult onset disease and sperm epimutations.

    To define the clinical phenotype and natural history of sporadic adult-onset degenerative ataxia and to identify putative disease-causing mutations. The primary measure of disease severity was the Scale for the Assessment and Rating of Ataxia (SARA). DNA samples were screened for mutations using a high-coverage ataxia-specific gene panel in combination with next-generation sequencing. The analysis was performed on 249 participants. Among them, 83 met diagnostic criteria of clinically probable multiple system atrophy cerebellar type (MSA-C) at baseline and another 12 during follow-up. Positive MSA-C criteria (4.94 ± 0.74, p 10 years were designated sporadic adult-onset ataxia of unknown etiology/non-MSA (SAOA/non-MSA). Compared with MSA-C, SAOA/non-MSA patients had lower SARA scores (13.6 ± 6.0 vs 16.0 ± 5.8, p = 0.0200) and a slower annual SARA increase (1.1 ± 2.3 vs 3.3 ± 3.2, p = 0.0013). In 11 of 194 tested participants (6%), a definitive or probable genetic diagnosis was made. Our study provides quantitative data on the clinical phenotype and progression of sporadic ataxia with adult onset. Screening for causative mutations with a gene panel approach yielded a genetic diagnosis in 6% of the cohort. NCT02701036. © 2017 American Academy of Neurology.

  20. The History and Timing of Depression Onset as Predictors of Young-Adult Self-Esteem

    2010-01-01

    Depression often emerges early in the lifecourse and is consistently shown to be associated with poor self-esteem. The three main objectives of the current study are to (1) evaluate the association between a history major depression and self-esteem in young adulthood; (2) assess the relationship between timing of depression onset and young adult self-esteem; and (3) help rule out the alternative interpretation that the relationship between major depression and self-esteem is due to state dependence bias stemming from recent depressive symptoms and stressful life events. To address these objectives we use data from a two-wave panel study based on a community sample of young adults in Miami-Dade County, Florida (n = 1,197). Results indicated a history of major depression during sensitive periods of social development is associated with negative changes in self-esteem over a two-year period during the transition to young adulthood. Among those with a history of depression, earlier onset was more problematic than later onset for young adult self-esteem, although the difference disappeared once the level of self-esteem two years prior was controlled. The linkages between the history and timing of depression onset with self-esteem were observed net of recent depressive symptoms and stressful life events, and thus robust to an alternative interpretation of state dependence. The findings support the argument that major depression, especially if it develops earlier during child-adolescent development, has negative consequences for one’s self-esteem. PMID:21860585

    Many non-communicable diseases (NCDs) are largely preventable via behaviour change and healthy lifestyle, which may be best established during childhood. This study sought insights into Chinese new immigrant mothers' perceptions about adult-onset NCDs prevention during childhood. Twenty-three semi-structured interviews were carried out with new immigrant mothers from mainland China who had at least one child aged 14 years or younger living in Hong Kong. Interviews were audio taped, transcribed and analysed using a Grounded Theory approach. The present study identified three major themes: perceived causes of adult NCDs, beliefs about NCDs prevention and everyday health information practices. Unhealthy lifestyle, contaminated food and environment pollution were perceived as the primary causes of adult NCDs. Less than half of the participants recognized that parents had responsibility for helping children establish healthy behaviours from an early age to prevent diseases in later life. Most participants expressed helplessness about chronic diseases prevention due to lack of knowledge of prevention, being perceived as beyond individual control. Many participants experienced barriers to seeking health information, the most common sources of health information being interpersonal conversation and television. Participants' everyday information practice was passive and generally lacked awareness regarding early prevention of adult-onset NCDs. Updated understanding of this issue has notable implications for future health promotion interventions. © The Author (2014). Published by Oxford University Press. All rights reserved.

    Advances in the management of children with chronic liver disease have enabled many to survive into adulthood with or without their native livers, so that the most common of these conditions are becoming increasingly common in adult hepatology practice. Because the aetiologies of chronic liver disease in children may vary significantly from those in adulthood, adults with paediatric-onset chronic liver disease may often present with clinical manifestations unfamiliar to their adulthood physician. Transition of medical care to adult practice requires that the adulthood medical staff (primary physicians and subspecialists) have a comprehensive knowledge of childhood liver disease and their implications, and of the differences in caring for these patients. Pending still unavailable Scientific Society guidelines, this article examines causes, presentation modes, evaluation, management, and complications of the main paediatric-onset chronic liver diseases, and discusses key issues to aid in planning a program of transition from paediatric to adult patients.

    The behavioral outcomes of a calorie restricted diet are often neglected in favour of a more physiological examination of the consequences of calorie restriction (CR). This is especially the case with social behavior. A few findings within the maternal CR literature suggest that adult male social behavior is altered by this regimen. Despite the paucity of findings within the maternal CR literature, a systematic investigation of the behavioral phenotype of males administered an adult-onset CR is completely lacking and was the focus of the current study. Adult male hooded Wistar rats were administered a three week CR, with one group receiving a 25% CR and another group receiving a 50% CR before male-to-male social behavior was examined and compared with ad libitium fed males. Various behavioral elements were modulated by CR, both the CR25% and 50% group initiated contact sooner and engaged in greater social activity compared to the ad libitum fed controls. The CR25% group also demonstrated less non-social (self-grooming) behavior and a greater frequency of walkovers compared to all groups, indicating a propensity towards dominance. The CR50% group demonstrated greater environmental assessment/exploration, as measured by the frequency of rearing. As with the maternal CR literature, an adult-onset chronic CR induces a more socially active behavioral phenotype and reduces interest in non-social behavior in the moderately CR group. Taken together, the social behavioral phenotype can be modulated by a CR initiated and maintained during adulthood.

    Genetic counselling for adults is not classical since it deals with prospective assessment of risk in developing disease. 1% of adults have a monogenic disease, or are carriers of a genotype predisposing to a disease. Situations that need genetic counselling are: confirmation of a diagnosis of an inherited disease already known in the family; discovery of a new genetic disease in an adult with no family history of the disease (reduced penetrance); and presymptomatic and prenatal diagnosis for late onset diseases. The prescription of presymptomatic testing is limited to the intervention of multidisciplinary teams, bringing together medical expertise and notified to needed. This is a special situation because it is not always followed by a preventive action or treatment.

    Full Text Available Environmental compounds including fungicides, plastics, pesticides, dioxin and hydrocarbons can promote the epigenetic transgenerational inheritance of adult-onset disease in future generation progeny following ancestral exposure during the critical period of fetal gonadal sex determination. This study examined the actions of the pesticide methoxychlor to promote the epigenetic transgenerational inheritance of adult-onset disease and associated differential DNA methylation regions (i.e. epimutations in sperm. Gestating F0 generation female rats were transiently exposed to methoxychlor during fetal gonadal development (gestation days 8 to 14 and then adult-onset disease was evaluated in adult F1 and F3 (great-grand offspring generation progeny for control (vehicle exposed and methoxychlor lineage offspring. There were increases in the incidence of kidney disease, ovary disease, and obesity in the methoxychlor lineage animals. In females and males the incidence of disease increased in both the F1 and the F3 generations and the incidence of multiple disease increased in the F3 generation. There was increased disease incidence in F4 generation reverse outcross (female offspring indicating disease transmission was primarily transmitted through the female germline. Analysis of the F3 generation sperm epigenome of the methoxychlor lineage males identified differentially DNA methylated regions (DMR termed epimutations in a genome-wide gene promoters analysis. These epimutations were found to be methoxychlor exposure specific in comparison with other exposure specific sperm epimutation signatures. Observations indicate that the pesticide methoxychlor has the potential to promote the epigenetic transgenerational inheritance of disease and the sperm epimutations appear to provide exposure specific epigenetic biomarkers for transgenerational disease and ancestral environmental exposures.

    Enterobacteriaceae is a leading pathogen of community-onset bacteremia. This study aims to establish a predictive scoring algorithm to identify adults with community-onset Enterobacteriaceae bacteremia who are at risk for abscesses. Of the total 1262 adults, 152 (12.0%) with abscess occurrence were noted. The 6 risk factors significantly associated with abscess occurrence-liver cirrhosis, diabetes mellitus, thrombocytopenia and high C-reactive protein (>100 mg/L) at bacteremic onset, delayed defervescence, and bacteremia-causing Klebsiella pneumoniae-were each assigned +1 point to form the scoring algorithm. In contrast, the elderly, fatal comorbidity (McCabe classification), and bacteremia-causing Escherichia coli were each assigned -1 point, owing to their negative associations with abscess occurrence. Using the proposed scoring algorithm, a cut-off value of +1 yielded a high sensitivity (85.5%) and an acceptable specificity (60.4%). Although the proposed predictive model needs further validation, this simple scoring algorithm may be useful for the early identification of abscesses by clinicians.

    Pigmented orthochromatic leukodystrophy (POLD) and Hereditary diffuse leukoencephalopathy with spheroids HDLS are two adult onset leukodystrophies with neuroaxonal spheroids presenting with prominent neurobehavioral, cognitive, and motor symptoms. These are familial or sporadic disorders characterized by cerebral white matter degeneration including myelin and axonal loss, gliosis, macrophages, and axonal spheroids. We report clinical, neuroimaging and pathological correlations of four women ages 34–50 years with adult onset leukodystrophy. Their disease course ranged from 1.5–8 years. Three patients had progressive cognitive and behavioral changes whereas one had acute onset. Neuroimaging revealed white matter abnormalities characterized by symmetric, bilateral, T2 hyperintense and T1 hypointense MRI signal involving frontal lobe white matter in all patients. Extensive laboratory investigations were negative apart from abnormalities in some mitochondrial enzymes and immunologic parameters. Autopsies demonstrated severe leukodystrophy with myelin and axonal loss, axonal spheroids, and macrophages with early and severe frontal white matter involvement. The extent and degree of changes outside the frontal lobe appeared to correlate with disease duration. The prominent neurobehavioral deficits and frontal white matter disease provides clinical-pathologic support for association pathways linking distributed neural circuits subserving cognition. These observations lend further support to the notion that white matter disease alone can account for dementia. PMID:18422757

    Full Text Available Pica has been considered as the ingestion of inedible substances or atypical food combinations. Pica has been reported widely in pediatric age group and often found to be co existing with obsessive compulsive or major depressive disorder. Reports of pica in elderly age group are relatively uncommon and rarely does it have an adult onset. In this article we present a case of adult onset pica. A young lady with unusual sensation in her abdomen was found to consume iron nails over years and there was history of dyspareunia since her marriage three months back. On query it was known that the lady is having same sex relationship over years. There unique conglomeration of cultural, psychodynamic and physiological determinants which together is responsible for this unusual habit of this lady. Moreover the onset of the disease at a late age and different psychodynamic issues make the case all the more interesting. Whether the pica is an eating disorder or obsessive compulsive disorder is still controversial. Pica has been mentioned in Diagnostic and Statistical Manual IV TR. The present case report warrants the need to look into this entity more closely with regards to its occurrence and etiology.

    2013-11-01

    Ankylosing spondylitis (AS) has 2 main modes of onset: juvenile-onset AS (JoAS) and adult-onset AS (AoAS). It is not known whether JoAS is a subtype of AS, or AS modulated by early age of onset and longer disease duration. We performed a systematic review of the literature, identifying 12 articles and 1 abstract directly comparing JoAS and AoAS cohorts, with observational study design. Patients with JoAS appear to have more peripheral joint involvement both clinically and radiographically (especially knees and ankles) and more root joint involvement (hips and shoulders); they are more likely to proceed to hip arthroplasty and often initially present with peripheral rather than axial symptoms. Patients with AoAS appear to have more axial symptoms and radiographic disease, particularly in the lumbar spine, and worse axial metrology. In terms of other characteristics, more evidence is needed to confidently state whether JoAS and AoAS are different.

    Hashimoto's encephalopathy is defined by the coexistence of encephalopathy and antithyroid antibodies. We report two cases of adult-onset temporal lobe epilepsy with subacute cognitive decline, high titers of antithyroid antibodies, multi-antiepileptic drug hypersensitivity, and good response to immunomodulatory treatment. The relevance of multidrug hypersensitivity in the setting of adult-onset epilepsy and the importance of searching for autoimmune causes for epilepsy are discussed.

    A 54-year-old man was admitted to our hospital for evaluation of hypoglycemia. He had frequent episodes of loss of concentration before dinner. The ratio of IRI to plasma glucose (PG) was 0.8-1.0. Abdominal CT revealed no pancreatic tumor, and angiography of splenic artery showed no definite tumor stain within the pancreas. Based on the results of selective arterial calcium stimulation and hepatic venous sampling (ASVS), the provisional diagnosis was a small insulinoma in the pancreatic body. The patient underwent subtotal distal pancreatectomy. However, histopathological and immunohistochemical examinations of the resected tissue showed hypertrophy of islets of Langerhans islands and beta cells around pancreatic ducts. The final diagnosis was adult-onset nesidioblastosis. Postoperatively, the patient continued to exhibit hyperinsulinemia and nighttime hypoglycemia. Octreotide, voglibose and diet therapies failed to improve the nocturnal hypoglycemia. However, treatment with diazoxide at a starting dose of 200 mg/day resulted in immediate amelioration of nocturnal hypoglycemia. This is the first Japanese adult case of nesidioblastosis treated successfully with diazoxide. This case report suggests that diazoxide may be effective for adult-onset nesidioblastosis in a manner similar to that described for pediatric cases.

    Although some patients with supratentorial gliomas develop epilepsy in their clinical course, the details of adult-onset epilepsy with gliomas have not been fully evaluated. This paper reports on 15 cases of supratentorial glioma with the sole symptom of adult-onset epilepsy and characterizes their clinical and MRI features. The patients, 5 males and 10 females, developed the first epilepsy at the mean age of 37 years. Generalized seizure was encountered in all cases and focal seizure alone was never seen. Seizure was satisfactorily controlled with anticonvulsants in all except 2 cases. The tumor was located in the frontal lobe (9 cases) or temporal lobe (6 cases). Histologically, there were 12 astrocytomas, 2 glioblastomas, and 1 oligoastrocytoma. Of these, 12 were benign gliomas. Surprisingly, CT scan and MRI revealed tumors larger than predicted. The abnormal intensity region was delineated most prominently on T[sub 2]-weighted SE image and was broader on T[sub 2]-weighted spin echo image than on T[sub 1]-weighted spin echo and inversion recovery image. The authors conclude that gliomas presenting with epilepsy tend to be histologically benign, are predominantly seen in middle-aged women, and are located in the frontal and temporal lobes. Although a tumor may be large enough to be detected on CT scan or MRI, as in the present study, histological examination is needed to establish the diagnosis. Additionally, gliomas with equivocal abnormalities on CT and MRI do evolve despite further neurological deficits, so meticulous evaluation including stereotactic biopsy is the method of choice. Finally, T[sub 2]-weighted SE image in the coronal plane is advocated for patients with adult-onset epilepsy to achieve accurate diagnosis and to initiate early treatment. (author).

    A 54-year-old woman presented to a foot centre with a chief symptom of cramping in her toes, which, she believed, was of a secondary cause originating from a bunion. She was treated conservatively; however, she returned a month later as the symptoms had progressed to painful cramping of toes, toe-curling and instability while walking, due to involuntary movement of her toes. It was believed that the patient presented with a rare case of primary adult onset focal foot dystonia. This case report explains dystonia further in detail and delves into the different treatment and management options available today, including the unique orthopaedic intervention provided for this patient.

    Paraneoplastic syndromes (PS) occur less commonly in association with otolaryngologic neoplasms than other carcinomas such as those of lung or breast. Piriform sinus carcinoma with PS is extremely rare. We here report a case of piriform sinus carcinoma accompanied by PS that was initially misdiagnosed as adult onset Still's disease and describe our diagnosis and treatment. One lesson we have drawn from the experience of this misdiagnosis is that PS symptoms may manifest before the primary tumor is evident and complicate the diagnostic process.

    Full Text Available A 22 year-old woman presented with multiple soft, compressible, protuberant, bluish cutaneous lesions as well as firm, non-compressible, subcutaneous masses and varicose veins affecting the right upper limb of three years duration. There was atrophy of soft tissue of forearm by 2.5 cm. X-ray showed soft tissue densities, multiple phleboliths and hypoplastic forearm bones. Histopathological examination from cutaneous lesions revealed cavernous hemangioma. Adult onset cavernous hemangioma involving one upper limb and breast with multiple phleboliths and limb atrophy is a very unusual presentation of Klippel-Trenaunay-Weber syndrome.

    Study Objectives: To determine if patients with childhood onsets (CO) of both major depression and insomnia disorder show blunted depression and insomnia treatment responses to concurrent interventions for both disorders compared to those with adult onsets (AO) of both conditions. Methods: This study was a secondary analysis of data obtained from a multisite randomized clinical trial designed to test the efficacy of combining a psychological/behavior insomnia therapy with antidepressant medication to enhance depression treatment outcomes in patients with comorbid major depression and insomnia. This study included 27 adults with CO of depression and insomnia and 77 adults with AO of both conditions. They underwent a 16-week treatment including: (1) a standardized two-step pharmacotherapy for depression algorithm, consisting of escitalopram, sertraline, and desvenlafaxine in a prescribed sequence; and (2) either cognitive behavioral insomnia therapy (CBT-I) or a quasi-desensitization control (CTRL) therapy. Main outcome measures were the 17-item Hamilton Rating Scale for Depression (HRSD-17) and the Insomnia Severity Index (ISI) completed pre-treatment and every 2 weeks thereafter. Results: The AO and CO groups did not differ significantly in regard to their pre-treatment HRSD-17 and ISI scores. Mixed model analyses that adjusted for the number of insomnia treatment sessions attended showed that the AO group achieved significantly lower, subclinical scores on the HRSD-17 and ISI than did the CO group by the time of study exit. Moreover, a significant group by treatment arm interaction suggested that HRSD-17 scores at study exit remained significantly higher in the CO group receiving the CTRL therapy than was the case for the participants in the CO group receiving CBT-I. Greater proportions of the AO group achieved a priori criteria for remission of insomnia (49.3% vs. 29.2%, p = 0.04) and depression (45.5% vs. 29.6%, p = 0.07) than did those in the CO group

    The aim was to reevaluate a group of adults treated for idiopathic childhood onset GH deficiency (GHD) after 18 yr without GH treatment. Twenty-six (11 females) patients participated. All but two had isolated GHD. Childhood diagnosis was established by insulin tolerance test (ITT). The patients...... were retested with an ITT to evaluate adult GH status. In five patients, an arginine and a synacthen test were performed instead of an ITT. Eleven of 25 patients had a subnormal cortisol response to ITT or synacthen. Ten patients had a GH peak less than 3.0 microg/liter (0.5. +/- 0.5 microg....../liter), whereas 16 patients displayed a normal GH response (12.3 +/- 10.6 microg/liter) after ITT. IGF-I values were decreased in the patients with a pathological retest as well as in patients with a normal GH response compared with controls (P

    Full Text Available This is a case of a 26-year-old active duty male with a history of idiopathic thrombocytopenic purpura (ITP and surgical asplenia who presented with a one-week history of fevers, myalgias, arthralgias, and rigors. His evaluation upon presentation was significant for a temperature of 103 degrees F, white blood cell count of 36 K with a granulocytic predominance, and elevated transaminases. He was treated empirically with broad-spectrum antibiotics with concern for a systemic infection with an encapsulated organism. During his stay, he developed four SIRS criteria and was transferred to the progressive care unit for suspected sepsis. He continued to have twice-daily fevers and a faint, salmon-colored centripetal rash was eventually observed during his febrile episodes. After a nondiagnostic microbiologic and serologic workup, he was diagnosed with adult-onset Still’s Disease and started on intravenous methylprednisolone with brisk response. He was discharged on oral prednisone and was started on anakinra. Adult-onset Still’s disease is a rare condition that presents with varying severity, and this is the first reported case, to our knowledge, of its diagnosis in an asplenic patient. Its management in the setting of asplenia is complicated by the need for antibiotic therapy with each episode of fever.

    Advances in genetic testing and the availability of such testing in pregnancy allows prospective parents to test their future child for adult-onset conditions. This ability raises several complex ethical issues. Prospective parents have reproductive rights to obtain information about their fetus. This information may or may not alter pregnancy management. These rights can be in conflict with the rights of the future individual, who will be denied the right to elect or decline testing. This paper highlights the complexity of these issues, details discussions that went into the National Society of Genetic Counselors (NSGC) Public Policy Task Force's development of the Prenatal testing for Adult-Onset Conditions position statement adopted in November 2014, and cites relevant literature on this topic through December 2015. Issues addressed include parental rights and autonomy, rights of the future child, the right not to know, possible adverse effects on childhood and the need for genetic counseling. This paper will serve as a reference to genetic counselors and healthcare professionals when faced with this situation in clinical practice.

    Adult-onset stuttering (AS) typically occurs following neurological and/or psychological trauma, considered different from developmental stuttering (DS), which starts during early childhood with few if any new cases reported after adolescence. Here we report four cases of AS, two with apparent psychological trigger and two without, none with evidence of neurological injury, and none conforming to previously reported characteristics of psychogenic stuttering. We asked whether this group of AS would have similar speech and neuroanatomical characteristics to those with DS. We conducted blinded analyses of speech samples in both AS cases and 14 cases of DS on type, frequency, and loci of disfluencies. Diffusion tensor imaging (DTI) was conducted to compare white matter tracts using fractional anisotropy (FA). We found that AS did not differ significantly from DS in any of the speech characteristics measured. On DTI, DS had significantly increased FA relative to controls in the right superior longitudinal tract. AS cases showed a similar trend for increases in these regions when compared to controls. The results of this study suggest that symptoms of idiopathic stuttering can begin during adulthood, and that similar neuroanatomical differences from controls may be associated with both developmental and adult onset idiopathic stuttering.

    Reports of increased incidence of adult onset stuttering in veterans and service members with mild traumatic brain injury (mTBI) from combat operations in Iraq and Afghanistan lead to a reexamination of the neurogenic vs. psychogenic etiology of stuttering. This article proposes to examine the merit of the dichotomy between neurogenic and psychogenic bases of stuttering, including symptom exaggeration, for the evaluation and treatment of the disorder. Two case studies of adult onset stuttering in service members with mTBI from improvised explosive device blasts are presented in detail. Speech fluency was disrupted by abnormal pauses and speech hesitations, brief blocks, rapid repetitions, and occasional prolongations. There was also wide variability in the frequency of stuttering across topics and conversational situations. Treatment focused on reducing the frequency and severity of dysfluencies and included educational, psychological, environmental, and behavioral interventions. Stuttering characteristics as well as the absence of objective neurological findings ruled out neurogenic basis of stuttering in these two cases and pointed to psychogenic causes. However, the differential diagnosis had only limited value for developing the plan of care. The successful outcomes of the treatment serve to illustrate the complex interaction of neurological, psychological, emotional, and environmental factors of post-concussive symptoms and to underscore the notion that there are many facets to symptom presentation in post-combat health.

    Full Text Available Adult onset Still’s disease (AOSD is a rare inflammatory disorder of unknown etiology that usually affects young adults. Very few patients older than 70-year-old have been reported. Clinical features include quotidian fevers, arthralgias, arthritis, pharyngitis, lymphadenopathy and an evanescent rash. AOSD should be considered in the differential diagnosis of fever of unknown origin. Early diagnosis is often difficult since it is a diagnosis of exclusion and the presence of infectious, neoplastic and autoimmune conditions needs to be ruled out before the diagnosis is made. No specific laboratory tests are available to aid in the diagnosis of AOSD. As a result, a set of diagnostic criteria that define the clinical features of this condition, termed the Yamaguchi criteria, have been most commonly used to establish the diagnosis. We describe the case of a 72-year-old Caucasian male with past medical history significant for generalized anxiety disorder, depression, BPH, and hypertriglyceridemia, who presented to a tertiary institution complaining of profound generalized weakness and weight loss that started three weeks prior to presentation. Initial laboratory studies showed leukocytosis, elevated ESR, CRP, ferritin and liver dysfunction. Cultures, ANA and rheumatoid factor studies were negative. The patient underwent further extensive workup that excluded the presence of infectious, neoplastic and autoimmune disorders and was subsequently diagnosed with AOSD and new onset diabetes mellitus. For the management of AOSD he was started on prednisone with significant improvement in markers of inflammation, symptoms and level of function.

This review presents a comprehensive synopsis of their epidemiology, pathophysiology, and clinical presentations; describes how they can be distinguished; and considers both established and proposed new approaches to their management. Both adult-onset asthma and COPD are complex diseases arising from gene–environment interactions. Early life exposures such as childhood infections, smoke, obesity, and allergy influence adult-onset asthma. While the established environmental risk factors for COPD are adult tobacco and biomass smoke, there is emerging evidence that some childhood exposures such as maternal smoking and infections may cause COPD. Asthma has been characterized predominantly by Type 2 helper T cell (Th2 cytokine-mediated eosinophilic airway inflammation associated with airway hyperresponsiveness. In established COPD, the inflammatory cell infiltrate in small airways comprises predominantly neutrophils and cytotoxic T cells (CD8 positive lymphocytes. Parenchymal destruction (emphysema in COPD is associated with loss of lung tissue elasticity, and small airways collapse during exhalation. The precise definition of chronic airflow limitation is affected by age; a fixed cut-off of forced expiratory volume in 1 second/forced vital capacity leads to overdiagnosis of COPD in the elderly. Traditional approaches to distinguishing between asthma and COPD have highlighted age of onset

    Axial myopathy can be the underlying cause of rapidly progressive adult-onset scoliosis; however, the pathogenesis of this disorder remains poorly understood. Here we present a case of a 69-year old woman with a family history of scoliosis affecting both her mother and her son, who over 4 years developed rapidly progressive scoliosis. The patient had a history of stable scoliosis since adolescence that worsened significantly at age 65, leading to low back pain and radiculopathy. Paraspinal muscle biopsy showed morphologic evidence of a mitochondrial myopathy. Diagnostic deficiencies of electron transport chain enzymes were not detected using standard bioassays, but mitochondrial immunofluorescence demonstrated many muscle fibers totally or partially deficient for complexes I, III, IV-I, and IV-IV. Massively parallel sequencing of paraspinal muscle mtDNA detected multiple deletions as well as a 40.9% heteroplasmic novel m.12293G > A (MT-TL2) variant, which changes a G:C pairing to an A:C mispairing in the anticodon stem of tRNA Leu(CUN). Interestingly, these mitochondrial abnormalities were not detected in the blood of either the patient or her son, suggesting that the patient's rapidly progressive late onset scoliosis was due to the acquired paraspinal mitochondrial myopathy; the cause of non-progressive scoliosis in the other two family members currently remains unexplained. Notably, this case illustrates that isolated mitochondrial myopathy can underlie rapidly-progressive adult-onset scoliosis and should be considered in the differential diagnosis of the primary axial myopathy.

    Full Text Available Objective To evaluate efficacy and tolerability of retigabine (ezogabine, US adopted name in the adjunctive treatment of partial-onset seizures in adults. Retigabine is the first anticonvulsant in its class, decreasing neuronal excitability by opening voltage-gated potassium channels. Methods MEDLINE and EMBASE were systematically searched using search terms retigabine and ezogabine for randomized controlled trials published from 1980 through August 17, 2013. Additionally, articles relating to pharmacology, pharmacokinetics, tolerability and interactions were examined for inclusion. Published abstracts and websites of the Food and Drug Administration and European Medication Agency were reviewed for additional relevant information. Results One phase IIb and two phase III trials were identified. Retigabine has been reported to have dose dependent efficacy in adjunctive treatment of resistant partial-onset seizures in adults in doses of 600, 900 and 1200 mg/day. Similar to other anticonvulsants, the most common adverse events were central nervous system related. Retigabine has several unique adverse events compared to other anticonvulsants: urinary retention and, with extended use, pigment changes to the skin and retina. Retigabine is metabolized by glucuronidation and acetylation. There are few drug interactions with retigabine. Conclusions Retigabine has been shown to have efficacy when used as adjunctive therapy in partial-onset seizures. It has a novel mechanism of action, activation of voltage-gated potassium channels. It has less drug interactions than many other anticonvulsants because it is not metabolized through the P-450 system. Its place in therapy has yet to be determined, especially with recent reports of pigment discoloration of skin and the retina with extended use.

    Adults who stutter (AWS) have demonstrated atypical coordination of motor and sensory regions during speech production. Yet little is known of the speech-motor network in AWS in the brief time window preceding audible speech onset. The purpose of the current study was to characterize neural oscillations in the speech-motor network during preparation for and execution of overt speech production in AWS using magnetoencephalography (MEG). Twelve AWS and 12 age-matched controls were presented with 220 words, each word embedded in a carrier phrase. Controls were presented with the same word list as their matched AWS participant. Neural oscillatory activity was localized using minimum-variance beamforming during two time periods of interest: speech preparation (prior to speech onset) and speech execution (following speech onset). Compared to controls, AWS showed stronger beta (15–25 Hz) suppression in the speech preparation stage, followed by stronger beta synchronization in the bilateral mouth motor cortex. AWS also recruited the right mouth motor cortex significantly earlier in the speech preparation stage compared to controls. Exaggerated motor preparation is discussed in the context of reduced coordination in the speech-motor network of AWS. It is further proposed that exaggerated beta synchronization may reflect a more strongly inhibited motor system that requires a stronger beta suppression to disengage prior to speech initiation. These novel findings highlight critical differences in the speech-motor network of AWS that occur prior to speech onset and emphasize the need to investigate further the speech-motor assembly in the stuttering population.

    ADAM33, a member of the ADAM (a disintegrin and metalloprotease) gene family, is an asthma susceptibility gene originally identified by positional cloning. In the present study, we investigated the possible association of five single-nucleotide polymorphisms (SNPs) in the ADAM33 (rs511898, rs528557, rs44707, rs597980 and rs2787094) with adult-onset asthma in an Indian population. The study included 175 patients with mild intermittent ($n = 44$), mild persistent ($n = 108$) or moderate persistent ($n = 23$) subgroups of asthma, and 253 nonasthmatic control individuals. SNPs were genotyped with the help of restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) method, and data were analysed using chi-square test and logistic regression model. Bonferroni’s correction for multiple comparisons was applied for each hypothesis. Genotypes and allele frequencies of SNPs rs511898 and rs528557 were significantly associated with adult-onset asthma ($P = 0.010-\\lt 0.001$). A significant association of the homozygous mutant genotype and mutant alleles of SNPs rs2787094, rs44707 and rs597980 with the asthma was also observed ($P = 0.020-\\lt 0.001$). A positive association between asthma and haplotypes AGCCT, GGCCT, AGACT, GCAGT, GGACT, ACCCC and AGACC were also found ($P = 0.036-\\lt 0.001$, OR $= 2.07-8.49$). Haplotypes AGCGT, GCAGC, ACAGC, ACAGT, GGAGC and GGCGT appear to protect against asthma ($P = 0.013-\\lt 0.0001$, OR $= 0.34-0.10$). Our data suggest that ADAM33 gene polymorphisms serve as genetic risk factors for asthma in Indian adult population.

    Dysplasia epiphysealis hemimelica (DEH), or Trevor’s disease, is an osteocartilaginous epiphyseal overgrowth typically occurring in children. The literature reports 6 adult cases and none describe recurrence requiring additional procedures. We present a new-onset proximal tibial DEH in an adult recurring approximately 3 years after open excision. A 39-year-old female presented with a history of right knee pain, swelling, and instability. Physical examination revealed a firm proximal tibial mass. Computed tomography (CT) imaging showed an exophytic, lobulated, sclerotic mass involving the anterolateral margin of the lateral tibial plateau. Magnetic resonance imaging was suggestive of an osteochondroma. The patient underwent curettage of the lesion due to its periarticular location. Histology revealed benign and reactive bone and cartilage consistent with periosteal chondroma. Two and a half years later, the patient presented with a firm, palpable mass larger than the initial lesion. CT revealed a lateral tibial plateau sclerotic mass consistent with recurrent intra-articular DEH. A complete excision was performed and histology showed sclerotic bone with overlying cartilage consistent with exostosis. DEH is a rare epiphyseal osteocartilaginous outgrowth frequently occurring in the long bones of children less than 8 years old. DEH resembles an osteochondroma due to its pediatric presentation and similar histologic appearance. Adult-onset cases comprise less than 1% of reported cases. Recurrence rate after surgical intervention is unknown. Only 1 such case, occurring in a child, has been described. Clinicians contemplating operative treatment for DEH should note the potential for recurrence and consider complete excision. A follow-up period of several years may be warranted to identify recurrent lesions. PMID:28144583

    We aimed to compare long-term social outcomes in young adults with childhood-onset epilepsy (cases) with neurologically normal sibling controls. Long-term social outcomes were assessed at the 15-year follow-up of the Connecticut Study of Epilepsy, a community-based prospective cohort study of children with newly diagnosed epilepsy. Young adults with childhood-onset epilepsy with complicated (abnormal neurologic exam findings, abnormal brain imaging with lesion referable to epilepsy, intellectual disability (ID; IQ < 60) or informative history of neurologic insults to which the occurrence of epilepsy might be attributed), and uncomplicated epilepsy presentations were compared to healthy sibling controls. Age, gender, and matched-pair adjusted generalized linear models stratified by complicated epilepsy and 5-year seizure-free status estimated adjusted odds ratios (aORs) and 95% confidence intervals [CIs] for each outcome. The 15-year follow-up included 361 individuals with epilepsy (59% of initial cases; N = 291 uncomplicated and N = 70 complicated epilepsy; mean age 22 years [standard deviation, SD 3.5]; mean epilepsy onset 6.2 years [SD 3.9]) and 173 controls. Social outcomes for cases with uncomplicated epilepsy with ≥5 years terminal remission were comparable to controls; cases with uncomplicated epilepsy <5 years seizure-free were more likely to be less productive (school/employment < 20 h/week) (aOR 3.63, 95% CI 1.83-7.20) and not to have a driver's license (aOR 6.25, 95% CI 2.85-13.72). Complicated cases with epilepsy <5 years seizure-free had worse outcomes across multiple domains; including not graduating high school (aOR 24.97, 95% CI 7.49-83.30), being un- or underemployed (<20 h/week) (aOR 11.06, 95% CI 4.44-27.57), being less productively engaged (aOR 15.71, 95% CI 6.88-35.88), and not living independently (aOR 10.24, 95% CI 3.98-26.36). Complicated cases without ID (N = 36) had worse outcomes with respect to productive engagement (aOR 6.02; 95% CI 2

    Full Text Available Abstract Background HMO databases offer an opportunity for community based epidemiologic studies of asthma incidence, etiology and treatment. The incidence of asthma in HMO populations and the utility of HMO data, including use of computerized algorithms and manual review of medical charts for determining etiologic factors has not been fully explored. Methods We identified adult-onset asthma, using computerized record searches in a New England HMO. Monthly, our software applied exclusion and inclusion criteria to identify an "at-risk" population and "potential cases". Electronic and paper medical records from the past year were then reviewed for each potential case. Persons with other respiratory diseases or insignificant treatment for asthma were excluded. Confirmed adult-onset asthma (AOA cases were defined as those potential cases with either new-onset asthma or reactivated mild intermittent asthma that had been quiescent for at least one year. We validated the methods by reviewing charts of selected subjects rejected by the algorithm. Results The algorithm was 93 to 99.3% sensitive and 99.6% specific. Sixty-three percent (n = 469 of potential cases were confirmed as AOA. Two thirds of confirmed cases were women with an average age of 34.8 (SD 11.8, and 45% had no evidence of previous asthma diagnosis. The annualized monthly rate of AOA ranged from 4.1 to 11.4 per 1000 at-risk members. Physicians most commonly attribute asthma to infection (59% and allergy (14%. New-onset cases were more likely attributed to infection, while reactivated cases were more associated with allergies. Medical charts included a discussion of work exposures in relation to asthma in only 32 (7% cases. Twenty-three of these (72% indicated there was an association between asthma and workplace exposures for an overall rate of work-related asthma of 4.9%. Conclusion Computerized HMO records can be successfully used to identify AOA. Manual review of these records is

    Hemophagocytic Lymphystiocytosis is a rare and fatal complication of rheumatic diseases, particularly Adult Onset Still's Disease (AOSD). It may be precipitated with immunosuppressive drugs and with viral and bacterial infections. A diagnosis depends on a high index of suspicion associated to certain clinical manifestations (fever, rash, Splemomegaly, any cytology blood dyscrasia, hipertrigliceridemia, hiperfibrinogenemia, and others), as well as pathologic evidence of hemophagocitosis from bone marrow biopsy or tissue samples of affected organs. Therapy consists of high dose corticosteroids and immunosuppressive drugs. We present a 42 year old woman with AOSD in remission who developed HLH in spite of receiving therapy with high dose steroids and immunosuppressive drugs. She had 2 negative bone marrow aspirates. Evidence of Hemophagocytosis was detected in both bone marrow biopsies. Timely evaluation and recognition of the signs and symptoms of HLH is crucial for the prompt management and a decrease in the mortality associated with this disease.

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate. ARDS accompanied by AOSD has been rarely reported in the literature. In conclusion, in a patient with ARDS who does not respond to antibiotic treatment, the involvement of AOSD should be considered.

    Genetic counseling is important in any genetic testing situation in order to address the various issues related to obtaining a genetic diagnosis. Presymptomatic testing for adult-onset neurodegenerative disease, in particular, presents a complex counseling scenario. It is imperative to discuss the potential impact of test results on patients' family dynamics, insurability and employability, family planning, and future health in addition to ascertaining a complete understanding of recurrence, inheritance, and testing parameters. The Huntington disease presymptomatic testing protocol is well-defined and has been used for more than 10 years. These guidelines, which protect both patient and provider, can now be applied to other diseases as further presymptomatic testing capabilities are realized.

    A 17-year-old female patient was referred to the Infectious Diseases Ward because of fever lasting for 14 days. On admission to the hospital the patient was in a generally good state, without any abnormalities on physical examination. Laboratory investigation revealed elevated inflammatory markers. Diagnostic imaging comprising chest X-ray, abdominal ultrasonography, and echocardiography showed no abnormalities. During the hospitalization, there occurred episodes of fever with skin rash and musculoskeletal pain of the lower limbs. Procalcitonin concentrations continued to increase. C-reactive protein concentrations decreased during therapy, starting from 191 mg/l. On the 23(rd) day of the disease, edema of the feet, ankles, and knees appeared. On the basis of the clinical picture and after excluding other possible causes of fever, the patient was diagnosed with adult onset Still's disease. The procalcitonin concentration was normalized after 5 days of steroid therapy. The patient was discharged under ambulatory rheumatologic supervision.

    Hip dysplasia is a treatable developmental disorder that presents early in life but if neglected can lead to chronic disability due to pain, decreased function, and early osteoarthritis. The main causes of hip dysplasia in the young adult are residual childhood developmental dysplasia of the hip (DDH) and adolescent-onset acetabular dysplasia. These two distinct disease processes affect the growing hip during different times of development but result in a similar deformity and pathomechanism of hip degeneration. Routine screening for DDH and counseling regarding risks for acetabular dysplasia in families with a history of early hip osteoarthritis may allow early identification and intervention in these hips with anatomical risk factors for joint degeneration.

     Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder of unknown etiology. There is not currently any specific serological markers for AOSD , and  diagnosis still relying on the exclusion of other likely diagnoses. Yamaguchi's criteria are used as a diagnostic criterion which contains negative serologic markers for other collagen vascular diseases including systemic lupus erythematosus and rheumatoid arthritis. Here we report a 28-year-old woman with arthralgia, fever, rash, leukocytosis, lymphadenopathy, sore throat, abnormal liver function and negative rheumatoid factor and ANA but  seropositive for anti-CCP, anti-dsDNA, and C-ANCA. It seems that despite AOSD is considered as a seronegativedisorder; it should be remembered in patients with compatible findings who are seropositive.

    A nine-year-old neutered female mixed breed dog presented for evaluation following a five-day history of lethargy, inappetence, weakness, abdominal distension and generalised muscle atrophy. Persistent vatrial standstill with a junctional rhythm was identified on electrocardiogram. Echocardiogram identified moderate dilation of all cardiac chambers and mild thickening of the mitral and tricuspid valves. Serology was negative for Neospora caninum and Toxoplasma gondii. Permanent pacemaker implantation was performed in addition to endomyocardial and skeletal muscle biopsies. Cryosections from the biceps femoris muscle showed numerous nemaline rod bodies while endomyocardial biopsies were possibly consistent with end-stage myocarditis. Rod bodies have rarely been reported in the veterinary literature. To the authors' knowledge, this is the first report of adult-onset nemaline rod myopathy and hypothyroidism with concurrent cardiac disease in a dog. © 2012 British Small Animal Veterinary Association.

    Full Text Available Macrophage activation syndrome (MAS is a potentially fatal complication of Adult-Onset Still’s disease (Still’s disease. Whereas an increasing body of evidence supports interleukin-1 (IL-1 blockade as a promising treatment for Still’s disease, whether it is therapeutic for MAS associated with Still’s disease remains unclear. We report a 34-year-old Caucasian man with one-decade history of TNF-blockade-responsive seronegative arthritis who presented with abrupt onset of fever, serositis, bicytopenia, splenomegaly, hepatitis, and disseminated intravascular coagulation. Striking hyperferritinemia was noted without evidence of infection, malignancy, or hemophagocytosis on bone marrow biopsy. NK cells were undetectable in the peripheral blood, whereas soluble IL-2 receptor was elevated. His multiorgan disease resolved in association with methylprednisolone pulse therapy, Anakinra, and a tapering course of prednisone. This case reinforces the notion that Still’s disease is inherently poised to manifest MAS as one of the clinical phenotypes by shedding light on the role of IL-1 underlying both Still’s disease and related MAS.

    Abstract Background: Thymoma is a T cell neoplasm arising from the thymic epithelium that due to its immunological role, frequently undercover derangements of immunity such a tumors and autoimmune diseases. Methods: Herein, we report, to the best of our knowledge, the first description of an association between thymoma and adult onset Still disease (AOSD) in a 47-year-old man. The first one was occasionally detected 4 years later the diagnosis of AOSD, and surgically removed via right lateral thoracotomy. Histology confirmed an encapsulated thymic tumor (type AB sec. WHO-classification). Results: The AOSD was particularly resistant to the therapy, requiring a combination of immunosuppressant followed by anti-IL1R, that was the only steroids-sparing treatment capable to induce and maintain the remission. The differential diagnosis was particularly challenging because of the severe myasthenic-like symptoms that, with normal laboratory tests, were initially misinterpreted as fibromyalgia. The pathogenic link of this association could be a thymus escape of autoreactive T lymphocytes causing autoimmunity. Conclusion: Clinicians should be always include the possibility of a thymoma in the differential diagnosis of an unusual new onset of weakness and normal laboratories data, in particular once autoimmune disease is present in the medical history.

    This study evaluated the clinical characteristics, treatment outcomes, and complications of patients with adult onset Still's disease (AOSD) in our local Chinese population. Patients with AOSD attending our hospital from 2008 to 2011 were identified and followed up. Their clinical and laboratory features at presentation, as well as their disease progression, treatments, and outcomes were recorded and compared with other reported series. A total of 75 patients with AOSD were identified. Forty-four were female. Thirty-nine had disease onset between 16 and 35 years of age. The most common presenting features were fever (96%), arthritis (57.33%), rash (78.67%), and sore throat (49.3%). The acute phase response was marked in most patients, with elevated erythrocyte sedimentation rates (77.05%) and C-reactive protein levels (84.06%). Hyperferritinemia was present in 74.14% of cases, and serum ferritin (SF) levels declined after treatment in most cases. Liver abnormalities were usually transient, but were more severe in 5 patients. Most patients (92%) required corticosteroid therapy; of these, 33.3% also received disease-modifying antirheumatic drugs or immunosuppressive drugs. Sixty-four and 45.33% patients with AOSD achieved partial and complete remission, respectively, after 2 weeks of treatment, and 92% and 74.67%, respectively, after 1 month. The cumulative relapse rate was 45.3%. Patients with AOSD had complex symptoms with no specific laboratory findings. Reduced SF levels after treatment and liver abnormalities may be used to follow treatment outcome.

    We report the case of a 43-year-old woman presenting with nocturnal episodes of pain and screaming during sleep starting at age 30. There was no childhood or family history of parasomnia. The events had gradually become more frequent over the years, occurring in the first half of the night within 2 h of sleep onset. There were no triggers, and she had partial amnesia for the events. A diagnosis of adult-onset sleep terrors was made on clinical grounds and supported polysomnographically. Seizures and periodic limb movements were excluded as triggering factors. There was some mild sleep disordered breathing (predominantly non-desaturating hypopnea with a propensity for REM sleep of debatable significance). Imaging of the brain and spine and neurophysiological investigations ruled out lesions, entrapments, or neuropathies as possible causes of pain. Treatment (clonazepam, paroxetine, or gabapentin) was poorly tolerated and made no difference to the nocturnal episodes, while trazodone worsened them. This is the first report of hypnopompic psychic pain in association with a NREM parasomnia. We hypothesize that the pain may represent a sensory hallucination analogous to the more commonly recognized visual NREM parasomnia-associated hypnopompic visual hallucinations and that, as such, it may arise during arousal of the sensory neocortex as confabulatory response.

    Written autobiographies of 48 incarcerated adult male sexual offenders (22 rapists, 13 intrafamilial child molesters, and 13 extrafamilial child molesters) were used to generate retrospective self-report measures of their childhood maternal and paternal attachment, childhood sexual abuse experiences, and onset of masturbation. Contrary to expectation, the offenders as a combined group more often reported secure than they did insecure childhood maternal and paternal attachment. There were no differences between the three offender subgroups with respect to maternal attachment; however the rapists and the intrafamilial child molesters were more likely to report insecure paternal attachment than were the extrafamilial child molesters. There were no differences between these offender subgroups in the frequency with which childhood sexual abuse was reported. However, offenders with insecure paternal attachment were more likely to report having been sexually abused than were those with secure paternal attachment. Sexually abused offenders in turn reported earlier onset of masturbation than did those who were not sexually abused. These results are consistent with contemporary attachment models linking insecure childhood attachment to childhood sexual abuse, and with traditional conditioning models linking childhood sexual abuse, early masturbation, and sexual offending.

    Purpose: Skeletal muscle damage occurs following high-intensity or unaccustomed exercise; however, it is difficult to monitor damage to the respiratory muscles, particularly in humans. The aim of this study was to use clinical measures to investigate the presence of skeletal muscle damage in the inspiratory muscles. Methods: Ten healthy subjects underwent 60 minutes of voluntary inspiratory threshold loading (ITL) at 70% of maximal inspiratory pressure. Maximal inspiratory and expiratory mouth pressures, delayed onset muscle soreness on a visual analogue scale and plasma creatine kinase were measured prior to ITL, and at repeated time points after ITL (4, 24 and 48 hours post-ITL). Results: Delayed onset muscle soreness was present in all subjects 24 hours following ITL (intensity = 22 ± 6 mm; significantly higher than baseline p = 0.02). Muscle soreness was reported primarily in the anterior neck region, and was correlated to the amount of work done by the inspiratory muscles during ITL (r = 0.72, p = 0.02). However, no significant change was observed in maximal inspiratory or expiratory pressures or creatine kinase. Conclusions: These findings suggest that an intense bout of ITL results in muscle soreness primarily in the accessory muscles of inspiration, however, may be insufficient to cause significant muscle damage in healthy adults.

    Full Text Available Purpose. To characterize vitelliform lesions (VLs in adult-onset foveomacular vitelliform dystrophy (AOFVD and acquired vitelliform (AVL patients using multimodal image analysis. Methods. Retrospective study of twenty-eight eyes from nineteen patients diagnosed with AVL or AOFVD. They were evaluated by color fundus photographs, fundus autofluorescence (FAF, fluorescein angiography (FA, and spectral-domain optical coherence tomography (SD-OCT. Results. Bilateral VLs were associated with AOFVD (p=0.013. Regular and centered VLs were associated with AOFVD (p=0.004 and p=0.016, whereas irregular and noncentered lesions were more frequent in AVL patients. Visual acuity, greatest linear dimension (GLD, lesion height (LH, and pseudohypopyon were similar between groups. Whereas median LH and GLD in AVL group diminished significantly during follow-up (p=0.009 and p=0.001, AOFVD lesions tended to become larger and thicker. Conclusions. When consulting a patient presenting a VL with unknown age of onset, familial history, or previous retinal diseases, some aspects of multimodal imaging assessment may lead the ophthalmologist to a correct diagnosis.

    Background Genome-wide association studies have identified novel genetic associations for asthma, but without taking into account the role of active tobacco smoking. This study aimed to identify novel genes that interact with ever active tobacco smoking in adult onset asthma. Methods We performed a genome-wide interaction analysis in six studies participating in the GABRIEL consortium following two meta-analyses approaches based on 1) the overall interaction effect and 2) the genetic effect in subjects with and without smoking exposure. We performed a discovery meta-analysis including 4,057 subjects of European descent and replicated our findings in an independent cohort (LifeLines Cohort Study), including 12,475 subjects. Results First approach: 50 SNPs were selected based on an overall interaction effect at p<10−4. The most pronounced interaction effect was observed for rs9969775 on chromosome 9 (discovery meta-analysis: ORint = 0.50, p = 7.63*10−5, replication: ORint = 0.65, p = 0.02). Second approach: 35 SNPs were selected based on the overall genetic effect in exposed subjects (p <10−4). The most pronounced genetic effect was observed for rs5011804 on chromosome 12 (discovery meta-analysis ORint = 1.50, p = 1.21*10−4; replication: ORint = 1.40, p = 0.03). Conclusions Using two genome-wide interaction approaches, we identified novel polymorphisms in non-annotated intergenic regions on chromosomes 9 and 12, that showed suggestive evidence for interaction with active tobacco smoking in the onset of adult asthma.

    Objective: To describe acute EEG findings in HIV-infected adults with new-onset seizure, assess baseline clinical characteristics associated with EEG abnormalities, and evaluate the relationship between EEG abnormalities and recurrent seizure. Methods: Eighty-one HIV-infected adults with new-onset seizure had EEG recordings during their index admission. Baseline characteristics assessed included HIV stage, seizure semiology, serum and CSF studies, neuroimaging, cognitive function based on the Zambian Mini-Mental State Examination and International HIV Dementia Scale, and psychiatric symptoms using the Shona Symptom Questionnaire. We evaluated the relationship between baseline characteristics and EEG abnormalities. Patients were followed for seizure recurrence, and the association between acute EEG abnormalities and seizure recurrence was assessed. Death was a secondary outcome. Results: Fifty-five patients had abnormal EEGs (68%): 18 (22%) had interictal spikes (12) or a recorded seizure (6). Among baseline clinical characteristics, more advanced HIV disease (p = 0.039) and any imaging abnormality (p = 0.027) were associated with abnormal EEGs. Cortical (p = 0.008) and white matter (p = 0.004) abnormalities were associated with slow posterior dominant rhythm. Patients were followed for a median of 303 days (interquartile range 103–560). Twenty-four (30%) died and 23 (28%) had recurrent seizures. EEG abnormalities were not associated with recurrent seizure. There was a nonsignificant association between seizures recorded during EEG and death (67% vs 26%, p = 0.051). Conclusions: EEG abnormalities are common in this population, particularly in patients with imaging abnormalities and advanced HIV. Acute EEG abnormalities were not associated with recurrent seizure, but high mortality rates during follow-up limited this analysis. PMID:25740861

      Studies performed at the beginning of the last century revealed the importance of carbohydrate as a fuel during exercise, and the importance of muscle glycogen on performance has subsequently been confirmed in numerous studies. However, the link between glycogen depletion and impaired muscle...... function during fatigue is not well understood and a direct cause-and-effect relationship between glycogen and muscle function remains to be established. The use of electron microscopy has revealed that glycogen is not homogeneously distributed in skeletal muscle fibres, but rather localized in distinct...... pools being of key importance for SR Ca2+ release and thereby affecting muscle contractility and fatigability....

    Objective Despite a prevailing assumption that adult ADHD is a childhood-onset neurodevelopmental disorder, no prospective-longitudinal study has described the childhoods of the adult-ADHD population. We report follow-back analyses of ADHD cases diagnosed in adulthood, alongside follow-forward analyses of ADHD cases diagnosed in childhood, in one cohort. Method Participants belonged to a representative birth cohort of 1,037 individuals born in Dunedin, New Zealand in 1972-73 and followed to age 38, with 95% retention. Symptoms of ADHD, associated clinical features, comorbid disorders, neuropsychological deficits, GWAS-derived polygenic risk, and life impairment indicators were assessed. Data sources were participants, parents, teachers, informants, neuropsychological testing, and administrative records. Adult ADHD diagnoses used DSM5 criteria, apart from onset-age and cross-setting corroboration, which were study outcomes. Results As expected, the childhood-ADHD group showed 6% prevalence, male excess, childhood comorbid disorders, neurocognitive deficits, polygenic risk, and, despite having outgrown their ADHD diagnosis, residual adult life impairment. As expected, the adult-ADHD group showed 3% prevalence, gender balance, adult substance dependence, adult life impairment, and treatment contact. Unexpectedly, the childhood-ADHD and adult-ADHD groups comprised virtually non-overlapping sets; 90% of adult-ADHD cases lacked a history of childhood ADHD. Also unexpectedly, the adult-ADHD group did not show tested neuropsychological deficits in childhood or adulthood, nor did they show polygenic risk for childhood ADHD. Conclusion Findings raise the possibility that adults presenting with the ADHD symptom picture may not have a childhood-onset neurodevelopmental disorder. If this finding is replicated, then the disorder's place in the classification system must be reconsidered, and research must investigate the etiology of adult ADHD. PMID:25998281

    2013-01-01

    Full Text Available Adult-onset Still’s disease is an inflammatory multisystemic disease of unknown etiology. Pleuritis is the most common pulmonary manifestation and pleural effusions are usually exudates with a predominance of neutrophils. We report a case of an eosinophilic pleural effusion as a novel and hitherto unrecognized manifestation of active adult-onset Still’s disease. We also observed a marked NLRP3 inflammasome activation with increased production of IL-1β which coincided with the development and resolved upon remission of the pleural effusion suggesting a possible novel pathogenetic pathway for the development of pleural effusions in the context of the auto-inflammatory disorders.

    Type-1 diabetes (T1D) is a heterogeneous autoimmune disease, and there are pathogenetic differences between young- and adult-onset T1D patients. We hypothesized that the expressions of genes involved in costimulatory immune system pathways in peripheral blood are differently regulated in young- and adult-onset T1D. Study group I consisted of 80 children, adolescents, and young adults (age range 1.4-21.4 y; 31 controls and 49 T1D patients). Study group II consisted of 48 adults (age range 22.0-78.4 y; 30 controls and 18 T1D patients). The mRNA expression levels of CD86, CD28, CD25, CD226, CD40, BTLA, GITR, PDCD1, FoxP3, TGF-β, ICOS, sCTLA4, flCTLA4, and CD80 were measured in peripheral blood. Genetic polymorphisms (HLA haplotypes; rs231806, rs231775, and rs3087243 in CTLA4; rs763361 in CD226; and rs706778 in CD25) and T1D-associated autoantibodies were analyzed. In group I, there was significantly lower expression of CD226 in T1D patients than in the controls. In group II, there were significantly higher expression levels of CD86 and TGF-β in T1D patients than in the controls. In the T1D patients in group I, the upregulated CD80 expression correlated with the expression of both CTLA4 splice variants (sCTLA4 and flCTLA4). In contrast, in group II, upregulated CD86 correlated with TGF-β and CD25. In group I, the inhibitory CD80-CTLA4 pathway was activated, whereas, in group II, the activation CD86-CD28 pathway and TGF-β production were activated. These results emphasize the differences between young-onset and adult-onset T1D in the regulation of costimulatory pathways. These differences should be considered when developing novel treatments for T1D.

  19. The impact of hearing loss in the life of adults: A comparison between congenital versus late onset hearing loss

    Full Text Available Aim of the Study: The aim of our study was to compare the impact of hearing loss in the life of adults who had congenital hearing loss with that of adults with acquired adult onset hearing loss (auditory neuropathy. Methodology: The quality of life scale questionnaire was administered on two groups. One group consisted of 10 adults with prelingual bilateral severe to profound hearing loss identified before the age of 3 years and who were using hearing aids and had received regular intervention for speech and language development by a qualified speech language pathologist. Second group consisted of 10 adults with auditory neuropathy. Results and Discussion: Wilcoxon rank sum test was used to compare the domains across the groups and the gender distributions between two groups were analyzed using Fisher′s exact test. The results revealed that differences between the adults with early-onset hearing loss and late onset hearing loss was statistically significant for most of the domains. The results indicated the fact that accepting a hearing loss during adulthood leads to more psychological trauma than adjusting and living with the hearing loss from the early years of life. Loss of hearing is quite traumatic to adults. Psychological trauma that they undergo is as important as their physiological problem and psychological referral to a clinical psychologist may be beneficial to many of them.

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder of unknown etiology and pathogenesis characterized by high spiking fever, arthralgia or arthritis, sore throat, lymphadenopathy, hepatosplenomegaly, serositis, and transient cutaneous manifestations. Although more common in children, cases are seen also in adults. Cutaneous involvement is common and may be suggestive for the diagnosis. A case of AOSD in a 35-year-old man is reported here, presenting with urticarial maculopapular rash of trunk, high spiking fever, acute respiratory distress syndrome, and myopericarditis. Skin biopsy showed interstitial and perivascular mature CD15(+) neutrophils. A comprehensive review of literature showed that cutaneous involvement occurs in about 80 % of patients, with various clinical presentations. The most common skin manifestation is an evanescent salmon pink or erythematous maculopapular exanthema, predominantly on the trunk and proximal limbs, with rare involvement of face and distal limbs. Less common manifestations include persistent erythematous plaques and pustular lesions. A constant histopathologic finding is the presence of interstitial dermal neutrophils aligned between the collagen bundles. This pattern may provide an easy accessible clue for the definitive diagnosis of AOSD and exclude other diagnosis such as drug eruptions or infectious diseases.

    Full Text Available ObjectiveTo identify a set of variables that could discriminate patients with adult-onset periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA syndrome from subjects with fever of unknown origin (FUO.MethodsWe enrolled 74 adults diagnosed with PFAPA syndrome according to the currently used pediatric diagnostic criteria and 62 additional patients with FUO. After having collected clinical and laboratory data from both groups, univariate and multivariate analyses were performed to identify the variables associated with PFAPA diagnosis. Odds ratio (OR values, their statistical significance, and corresponding 95% confidence interval (CI were evaluated for each diagnostic factor both at the univariate and multivariate analyses. Diagnostic accuracy was evaluated by the area under receiver operating characteristic (ROC curve, while the leave-one-out cross-validation procedure was used to ensure that the model maintains the same diagnostic power when applied to new data.ResultsAccording to the multivariate analysis, the clinical variables that discriminated PFAPA patients were: fever episodes associated with cervical lymphadenitis (OR = 92; p < 0.0001, fever attacks associated with erythematous pharyngitis (OR = 231; p < 0.0001, increased inflammatory markers during fever attacks (OR = 588; p = 0.001, and the lack of clinical and laboratory signs of inflammation between flares (OR = 1202; p < 0.0001. These variables were considered for a diagnostic model which accounted for their OR values. The diagnostic accuracy of the proposed set of criteria corresponded to an area under ROC curve of 0.978 (95% CI 0.958–0.998, with a model sensitivity and specificity equal to 93.4% (95% CI 87.5–96.5% and 91.7% (95% CI 82.8–96.7%, respectively.Conclusionwe have provided herein a set of clinical diagnostic criteria for adult-onset PFAPA syndrome.

    Full Text Available Objective: In adults with hyperinsulinaemic hypoglycaemia (HH, in particular those with insulinoma, the optimal diagnostic and management strategies remain uncertain. Here, we sought to characterise the biochemical and radiological assessment, and clinical management of adults with HH at a tertiary centre over a thirteen-year period. Design: Clinical, biochemical, radiological and histological data were reviewed from all confirmed cases of adult-onset hyperinsulinaemic hypoglycaemia at our centre between 2003 and 2016. In a subset of patients with stage I insulinoma, whole-exome sequencing of tumour DNA was performed. Results: Twenty-nine patients were identified (27 insulinoma, including 6 subjects with metastatic disease; 1 pro-insulin/GLP-1 co-secreting tumour; 1 activating glucokinase mutation. In all cases, hypoglycaemia (glucose ≤2.2 mmol/L was achieved within 48 h of a supervised fast. At fast termination, subjects with stage IV insulinoma had significantly higher insulin, C-peptide and pro-insulin compared to those with insulinoma staged I–IIIB. Preoperative localisation of insulinoma was most successfully achieved with EUS. In two patients with inoperable, metastatic insulinoma, peptide receptor radionuclide therapy (PRRT with 177Lu-DOTATATE rapidly restored euglycaemia and lowered fasting insulin. Finally, in a subset of stage I insulinoma, whole-exome sequencing of tumour DNA identified the pathogenic Ying Yang-1 (YY1 somatic mutation (c.C1115G/p.T372R in one tumour, with all tumours exhibiting a low somatic mutation burden. Conclusion: Our study highlights, in particular, the utility of the 48-h fast in the diagnosis of insulinoma, EUS for tumour localisation and the value of PRRT therapy in the treatment of metastatic disease.

    Full Text Available Abstract Background Genome-wide association studies of asthma have identified a novel region containing ORMDL3 at chromosome 17q21 that is strongly associated with childhood-onset asthma and significantly linked to ORMDL3 transcript abundance. These results have been successfully replicated in childhood-onset asthma cohorts in several ethnic groups. In this study, we aimed to evaluate the association of polymorphisms in ORMDL3, GSDMB, ZPBP2 and IKZF3 and adult-onset asthma in a Chinese Han population. Methods We genotyped 5 single nucleotide polymorphisms (SNPs at chromosome 17q21 in 1,366 Han Chinese people comprising 710 patients with adult-onset asthma and 656 healthy controls. We compared the 2 groups in terms of allele and haplotype frequencies. Transcript levels were measured in leukocytes from 61 asthma patients by quantitative real-time PCR. Results We found the 5 SNPs significantly associated with asthma (PORMDL3 and GSDMB in leukocytes (all p Conclusions Our replication study suggests that variants in 17q21 are significantly associated with risk of adult-onset asthma and gene expression in a Chinese Han population.

    SLC25A13 (citrin or aspartate-glutamate carrier 2) is located in the mitochondrial membrane in the liver and its genetic deficiency causes adult-onset type II citrullinemia (CTLN2). CTLN2 is one of the urea cycle disorders characterized by sudden-onset hyperammonemia due to reduced argininosuccinate synthase activity. This disorder is frequently accompanied with hepatosteatosis in the absence of obesity and ethanol consumption. However, the precise mechanism of steatogenesis remains unclear. The expression of genes associated with fatty acid (FA) and triglyceride (TG) metabolism was examined using liver samples obtained from 16 CTLN2 patients and compared with 7 healthy individuals. Although expression of hepatic genes associated with lipogenesis and TG hydrolysis was not changed, the mRNAs encoding enzymes/proteins involved in FA oxidation (carnitine palmitoyl-CoA transferase 1α, medium- and very-long-chain acyl-CoA dehydrogenases, and acyl-CoA oxidase 1), very-low-density lipoprotein secretion (microsomal TG transfer protein), and FA transport (CD36 and FA-binding protein 1), were markedly suppressed in CTLN2 patients. Serum concentrations of ketone bodies were also decreased in these patients, suggesting reduced mitochondrial β-oxidation activity. Consistent with these findings, the expression of peroxisome proliferator-activated receptor α (PPARα), a master regulator of hepatic lipid metabolism, was significantly down-regulated. Hepatic PPARα expression was inversely correlated with severity of steatosis and circulating ammonia and citrulline levels. Additionally, phosphorylation of c-Jun-N-terminal kinase was enhanced in CTLN2 livers, which was likely associated with lower hepatic PPARα. Collectively, down-regulation of PPARα is associated with steatogenesis in CTLN2 patients. These findings provide a novel link between urea cycle disorder, lipid metabolism, and PPARα.

    Centronuclear myopathies are congenital muscle disorders characterized by type I myofibre predominance and an increased number of muscle fibres with nuclear centralization. The severe neonatal X-linked form is due to mutations in MTM1, autosomal recessive centronuclear myopathy with neonatal or childhood onset results from mutations in BIN1 (amphiphysin 2), and dominant cases were previously associated to mutations in DNM2 (dynamin 2). Our aim was to determine the genetic basis and physiopathology of patients with mild dominant centronuclear myopathy without mutations in DNM2. We hence established and characterized a homogeneous cohort of nine patients from five families with a progressive adult-onset centronuclear myopathy without facial weakness, including three sporadic cases and two families with dominant disease inheritance. All patients had similar histological and ultrastructural features involving type I fibre predominance and hypotrophy, as well as prominent nuclear centralization and clustering. We identified heterozygous BIN1 mutations in all patients and the molecular diagnosis was complemented by functional analyses. Two mutations in the N-terminal amphipathic helix strongly decreased the membrane-deforming properties of amphiphysin 2 and three stop-loss mutations resulted in a stable protein containing 52 supernumerary amino acids. Immunolabelling experiments revealed abnormal central accumulation of dynamin 2, caveolin-3, and the autophagic marker p62, and general membrane alterations of the triad, the sarcolemma, and the basal lamina as potential pathological mechanisms. In conclusion, we identified BIN1 as the second gene for dominant centronuclear myopathy. Our data provide the evidence that specific BIN1 mutations can cause either recessive or dominant centronuclear myopathy and that both disorders involve different pathomechanisms. © The Author (2014).

    Cross-sectional survey. To describe the medications taken by individuals who had sustained a spinal cord injury (SCI) in childhood or adolescence (age polypharmacy and its association with demographic, injury-related and psychosocial factors. Community. Structured interviews of adults with pediatric-onset SCI. Routine medications and secondary health conditions (SHCs) experienced were recorded. Polypharmacy was defined as the concomitant use of five or more different types of medications. Bivariate analyses and multiple regression models were conducted to determine associations between polypharmacy and demographic factors, injury-related factors, number of SHCs and psychosocial outcomes (FIM, SF-12v2 Health Survey, CHART, PHQ-9). A total of 159 participants (male, 63%; tetraplegia, 59%) with mean age 35.0±6.2 years (range, 26.7-50.9 years) were included. Most common routine medications were muscle relaxants (50.3%), bladder medications (48.5%), bowel agents (41.5%), analgesics (26.4%) and antidepressants (16.9%). Polypharmacy was present in 30.8% (n, 49) and was more prevalent in those with tetraplegia (40.2% vs 17.9%; P=0.003). Participants with polypharmacy were older, had lower FIM, CHART and SF-12v2 scores, and higher PHQ-9 scores. Regression models indicate the total number of SHCs, time since injury and tetraplegia to be significant positive predictors of polypharmacy. Duration of SCI and SHCs are risk factors for polypharmacy in this population of adults with SCI. Measures should be taken to prevent the occurrence of SHCs throughout adulthood so as to prevent the potentially adverse physiological effects and psychosocial outcomes associated with polypharmacy.

    Youth with childhood-onset chronic illness (COCI) are at risk of poor educational attainment. Specific protective factors that promote college graduation in this population have not been studied previously. In this study, we examine the role protective factors during adolescence play in promoting college graduation among young adults with COCI. Data were collected from 10,925 participants in the National Longitudinal Study of Adolescent Health (Add Health). Protective factors present before 18 years of age included mentoring, parent relationship quality, school connectedness, and religious attendance. College graduation was the outcome of interest assessed when participants had a mean age of 28 years. Analysis was stratified by presence of COCI. About 2% of participants (N = 230) had 1 of 4 COCIs (cancer, diabetes, epilepsy, or heart disease). All 4 protective factors were associated with college graduation for youth without COCI. In the final multivariate model, only school connectedness was associated with college graduation for youth with COCI. School connectedness is of particular importance in promoting educational attainment for youth with COCI. © 2012, American School Health Association.

    Autosomal dominant adult-onset polycystic kidney disease (ADPKD) is estimated to have an incidence of 1/1,000 and accounts for approximately 10% of all end-stage renal disease in the United States. While relatives are attractive as renal donors due to their availability and the improved transplant success associated with living-related donors, they may coincidentally be at risk for ADPKD. Accurate presymptomatic testing for at-risk potential donors is critical for both the donor and the recipient. We report here 2 families in which presymptomatic testing for ADPKD was accomplished by DNA linkage analysis on several potential renal donors prior to transplant. This resulted in the protection of both donors and recipients by preventing the transplantation of a kidney affected by ADPKD. Thorough counseling prior to DNA analysis (including discussion of accuracy and possible testing outcomes of presymptomatic diagnosis of ADPKD, diagnosis of noncarrier status, false paternity, and non-informative study) was essential to provide informed consent and preserve confidentiality within the family. Confidentiality for potential donors found presymptomatically to be affected (with a 94% or greater probability) was especially difficult to maintain.

    Leucodystrophies are a heterogeneous group of progressive white matter diseases which may be inherited in dominant, recessive or X-linked fashion depending on the type. Adrenoleucodystrophy (ALD) and metachromatic leucodystrophy (MLD) are rather commoner forms of leucodystrophies whereas krabbes disease, alexander disease, cannavans disease etc. are of less common type. Adult-onset autosomal dominant leucodystrophy (ADLD) is a lately described rarer form of leucodystrophy with perhaps no case report from India. Various leucodystrophies may have different clinical presentations, ranging from subtle cognitive and psychiatric manifestations to gross motor disabilities, visual impairment and seizure. Psychiatric manifestations in the form of psychoses and frank schizophrenia are commonly described in MLD. Depression though uncommonly reported in MLD, cyclic mood disorders have been rarely described in any form of leucodystrophies. We are reporting an eye opener, a case of ADLD which masqueraded as a rapid cyclic mood disorder for initial four years, later to be followed by progressive neurological signs and symptoms. To the best of our knowledge, this is perhaps the first case report of ADLD presenting as rapid cyclic mood disorder in the world literature.

    The study aims to evaluate bothersome lower urinary tract symptoms (LUTS), risk factors, and associated functional abnormalities in women reporting adult onset secondary nocturnal enuresis (SNE), to help understand factors associated with SNE. 12,795 women (age >18) attending a tertiary referral centre underwent a comprehensive standardized evaluation including urodynamic testing in accordance with the International Continence Society recommendations. Records of all patients reporting bedwetting while asleep were evaluated under various categories. Multiple logistic regression was used to identify statistically significant risk factors and urodynamic findings associated with SNE. The prevalence of SNE in women undergoing urodynamic testing for bothersome LUTS was 14.4% (1,838). High BMI (OR = 1.47, P < 0.001), cigarette smoking (OR = 2, P < 0.001), antidepressant usage (OR = 1.8, P < 0.001), neurological conditions (OR = 2.12, P < 0.001), and previous hysterectomy (OR = 1.19, P = 0.03) were significantly associated with SNE. Women with SNE significantly complained of overactive bladder (OAB) symptoms (OR = 1.65, P < 0.001) and slightly higher mean nocturia episodes (OR = 1.38, P < 0.0001). Low maximum urethral closure pressure (MUCP) (OR = 1.34, P < 0.0001) and detrusor overactivity incontinence (DOI) (OR = 1.75, P < 0.0001) were significantly associated with SNE. There was no significant association with the symptom of stress urinary incontinence (P = 0.264), urodynamic stress incontinence (P = 0.454) or detrusor overactivity (P = 0.231). Women with adult SNE usually present with OAB symptoms. SNE is associated with high BMI, cigarette smoking, antidepressant use, and neurological conditions. DOI and a low MUCP are possible pathophysiological mechanisms in SNE. Neurourol. Urodynam. 36:188-191, 2017. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    Objective: To explore the effect of Tripterygium polyglycoside (TP) associated with nicotinamide on the islet cell function, immune parameters and lipoperoxide (LPO) in adult patients with late-onset autoimmune diabetes mellitus (LADA) Methods: Thirty-six cases of LADA were randomly divided into three groups: TP group (n= 12), treated with TP plus orally taken metformin; combined treatment group (n =12), treated with TP combined with nicotinamide and metformin, and control group (n = 12) treated with metformin alone. They were followed-up for 18 months. Results: (1) Compared with the control group after 9months of treatment, postprandial plasma glucose and LPO in combined treatment group were decreased (P <0.05), and the postprandial C-peptide was higher (P<0.05). At the 18th month, the value of postprandial C-peptide in the TP and combined treatment group was higher than that in the control group. The slL-2R level of both TP and combined treatment groups were lowered (P<0.01); (2) Islet cell antibody (ICA) positive of 5 cases in the TP group and 6 cases in the combined treatment group got converted to the negative respectively, while only one in the control group at the time (P<0.05) ; (3) The level of LPO in the combined treatment group was significantly lower than that in the TP group at the 18th month of treatment (P<0.05).Conclusion: TP combined with nicotinamide played a role in immunity regulation, decreasing the titer of islet cell antibody and slL-2R, which also reduced the production of LPO and had a tendency to improve islet cell function in early LADA patients.

    Background The psychiatric health burden of prisoners is substantial. However, there is a lack of high-quality studies of psychiatric disorders among young adults with a high risk of reoffending. Aims To investigate the lifetime prevalence of psychiatric disorders and use of mental health services among young male violent offenders and the impact of childhood-onset conduct disorder (COCD). Method A nationally representative cohort (n = 270, age 18–25) of male offenders was followed back in medical records and clinically assessed by gold standard methods. Lifetime prevalences are presented together with odds ratios (ORs) as risk estimates in relation to COCD. Results Previous use of psychiatric services among the participants was high but their lifetime psychiatric morbidity was even higher, with 93% meeting criteria for at least one Axis I disorder. The COCD group was overrepresented in most clinical categories and carried five times higher odds (OR = 5.1, 95% CI 2.0–12.8) of a psychotic disorder, three times higher odds (OR = 3.2, 95% CI 1.2–8.5) of a substance use disorder and two times higher odds of a mood disorder (OR = 2.3, 95% CI 1.3–4.0) or anxiety disorder (OR = 2.0, 95% CI 1.1–3.5). Conclusions The mental health burden is substantial among young violent offenders, and COCD is an important indicator of future mental health problems which must be a priority for public health efforts.

    Fetal exposure to parental smoking may lead to developmental adaptations and promote various diseases in later life. This study evaluated the associations of parental smoking during pregnancy with the risk of hypertension in the daughter in adulthood, and assessed whether these associations are explained by birth weight or body weight throughout life. We used data on 33086 participants of the Nurses' Health Study II and the Nurses' Mothers' Cohort. Cox proportional hazards models were used to examine the associations of maternal and paternal smoking during pregnancy with the nurse daughter, with self-reported physician-diagnosed hypertension from 1989 until 2007. Overall, 8575 (25.9%) mothers and 18874 (57.0%) fathers smoked during pregnancy. During follow-up, 7825 incident cases of adult-onset hypertension were reported. Both maternal and paternal smoking of ≥ 15 cigarettes/d during pregnancy were associated with increased risks of hypertension (rate ratio, 1.19; 95% CI, 1.09-1.29; and rate ratio, 1.18; 95% CI, 1.12-1.25, respectively) in the age-adjusted models. Further adjustment for birth weight did not affect the effect estimates appreciably, whereas additional adjustment for body shape and weight until age 18, or current body mass index, attenuated the associations with both maternal and paternal smoking (rate ratio, 1.07; 95% CI, 0.98-1.16; and rate ratio, 1.06; 95% CI, 1.01-1.12, respectively). The associations of parental smoking during pregnancy with the risk of hypertension in the offspring were largely explained by body weight throughout life, suggesting that these associations may not reflect direct intrauterine mechanisms.

    Hartnup disease is an inborn abnormality of renal and intestinal transport involving the neutral amino acids. Intermittent pellagra-like rash, attacks of cerebellar ataxia and psychiatric disturbance are characteristic symptoms of this disease. We described here a patient with adult-onset Hartnup disease who presented unique neuropsychiatric symptoms but no dermatologic symptoms, and reported features of amino acids transport in this patient and his family. The patient, a man aged 37 years, was referred to us because of lasting daytime bruxism. He is the second child of healthy parents who are first cousin; his elder brother who has been mentally retarded became bed-ridden and died at 32 years of age. His younger brother is completely healthy. Although the patient's development in infancy has been slightly retarded, he completed compulsory 9-year education. At 29 years of age, he experienced episodes of diplopia, ataxic gait and insomnia, and at 33 years of age, of transient stupor. There had been no history of photosensitivity or dermatitis. On neurological examination, there were trunkal ataxia, increased muscular tone and decreased mental activity besides bruxism. These symptoms remained unchanged despite of several medications including trihexyphenidyl, diazepam, halloperidol, tiapride and sulpiride. Two months later, the patient became stuporous; bruxism and hypertonicity became exaggerated. Myerson's sign, sucking reflex and grasp reflex in both hand appeared. There was no dermal lesion. A cranial computed tomography revealed a small calcification in the right frontal subcortical region and a single photon emission tomography indicated possible bifrontal hypoperfusion. Electroencephalograms demonstrated non-specific slowing. Somatosensory evoked potentials and nerve conduction velocities were normal. There were constant indicanuria and amino-aciduria.(ABSTRACT TRUNCATED AT 250 WORDS)

    The diagnosis of adult onset Still's disease (AOSD) is non‑specific, and requires the exclusion of other diseases including infectious, inflammatory and malignant diseases. The current study aimed to summarize the imaging characteristics of fluorodeoxyglucose (18F‑FDG) positron emission tomography (PET)/computerized tomography (CT) in patients with AOSD. The 18F‑FDG PET/CT characteristic observations of 32 patients with definite AOSD were retrospectively reviewed based on visual interpretation and the semi‑quantitative index of standard uptake value of maximum (SUVmax). Among 32 patients, no normal case was observed. Abnormal FDG accumulation by the spleen, bone marrow and lymph nodes was the main observation of the PET/CT images. Totals of 27 (84.4%) and 26 cases (81.3%) were identified with diffusely elevated FDG uptake by the spleen and bone marrow, respectively, and the average SUVmax was 4.2±1.1 and 4.6±0.6, respectively. A total of 20 cases (62.5%) showed lymphadenopathy with FDG uptake, with the range of SUVmax from 2.2‑13.9. In addition, 7 patients (21.9%) were observed to exhibit effusion without FDG uptake, 1 case presented with abnormal FDG uptake by the skin, and another by the right shoulder joint. In addition, no abnormally elevated FDG uptake by the liver or large vessels was observed. Due to non‑specific imaging features, 18F‑FDG PET/CT could not be directly helpful in diagnosing AOSD. However, 18F‑FDG PET/CT serves important roles in evaluating the involved extent of AOSD, and guiding the biopsy of lymph nodes, bone marrow or other tissues, which may aid in the development of novel clinical management strategies.

    Full Text Available The paper considers a case of adult-onset Still's disease that occurred as acute pericarditis, two-spike hectic fever, and neutrophilic leukocytosis in a young man. It was difficult to establish a correct diagnosis because there were no characteristic clinical symptoms of Still's disease, such as salmon colored rash, arthralgia, and sore throat. The diagnosis of adult-onset Still's disease was verified on the basis of the classification criteria described by M. Yamaguchi et al. The special feature of the clinical case was the development of steroid resistance and the effective use of a combination of the interleukin-6 receptor blocker tocilizumab (8 mg/kg body weight, given intravenously dropwise once every four weeks and methotrexate (15 mg/week orally. During this treatment, a sustained clinical and laboratory response was achieved, which could reduce the dose of glucocorticoids to the maintaining one.

    Hereditary periodic fever syndromes (HPFSs) are a group of inherited disorders of the innate immune system caused by mutations of genes involved in the regulation or activation of the inflammatory response, which belong to the category of autoinflammatory disorders. Most HPFs typically have an onset in pediatric age, while a limited number of patients experience disease onset during adulthood. The relative rarity and lack of information on adult-onset autoinflammatory diseases make it likely that genetic testing is often inconclusive. Recently, we have identified a set of variables related to the probability of detecting gene mutations in MEFV, responsible for familial Mediterranean fever, and TNFRSF1A, responsible for tumor necrosis factor receptor-associated periodic syndrome. In addition, we have proposed a diagnostic score for identifying those patients at high risk of carrying mutations in these genes. However, before the score can be recommended for application, further evaluation by means of longitudinal studies on different ethnicities and different populations deriving from other geographical areas is needed in order to definitively verify both its sensitivity and its specificity. The present manuscript offers our suggestions on how to establish a differential diagnosis for adult-onset HPFs, as well as a review of the literature, and we also provide a score revision available online.

    The transition of adult patients with childhood-onset chronic diseases (APCCD) from pediatric to adult health-care systems has recently received worldwide attention. However, Japan is lagging behind European countries and North America as this concept of health-care transition was introduced only 10 years ago. In Japan, before the introduction of this concept, APCCD were referred to as “carryover patients,” who were often considered a burden in pediatric practice. In the late 1990s, groups co...

    Myofibroma is a rare benign neoplasm of myofibroblastic origin. It typically occurs in the skin and subcutaneous tissues of the head and neck in infants and young children as multicentric lesions known as infantile myofibromatosis. Intraosseous myofibromas are very rare and are typically destructive lesions that predominantly affect craniofacial bones in the setting of myofibromatosis. Solitary, intraosseous myofibromas in adults are exceedingly rare. Herein, we report a myofibroma involving the middle phalanx of the right index finger in a 58-year-old man who presented with a pathologic fracture. Twelve other cases of adult-onset, intraosseous myofibroma were compiled from the English language literature and integrated with this report.

    To determine whether or not diabetes distress varies by age of type 1 diabetes mellitus (T1DM) onset and/or gender. A total of 700 adult T1DM patients were randomly selected from the Lithuanian Diabetes Registry; 214 of them (30.6%) agreed to participate and were recruited for the study. Diabetes distress (emotional burden, physician-related distress, regimen-related distress, interpersonal distress) was compared in 105 (42 men and 63 women) patients with T1DM diagnosed during 0-18years of life, and in 109 (61 men and 48 women) with T1DM diagnosed in adulthood, using Diabetes Distress Scale (DDS). Adult childhood-onset T1DM women have higher regimen-related distress (36.3±21.3 vs 26.6±16.2, p=0.016) than adulthood-onset women. Adult childhood-onset T1DM women experience higher diabetes distress (higher emotional burden (27.0±22.0 vs 15.6±16.4, p=0.006), physician-related distress (34.4±33.9 vs 20.7±29.4, p=0.024), total diabetes distress (41.2±13.6 vs 34.8±10.9, p=0.011)) than childhood-onset men. Adulthood-onset T1DM women experience higher physician-related distress (39.2±37.6 vs 23.4±32.5, p=0.013), but lower regimen-related distress (26.6±16.2 vs 35.8±21.6, p=0.014) than adulthood-onset men. In conclusion our findings reinforce the interdependence of psychological and biomedical factors in influencing health outcomes and support the need to provide psychological assessment and support to patients with T1DM.

  12. Glucide metabolism disorders (excluding glycogen myopathies).

    Science.gov (United States)

    Klepper, Joerg

    2013-01-01

    Glucide metabolism comprises pathways for transport, intermediate metabolism, utilization, and storage of carbohydrates. Defects affect multiple organs and present as systemic diseases. Neurological symptoms result from hypoglycemia, lactic acidosis, or inadequate storage of complex glucide molecules in neurological tissues. In glycogen storage disorders hypoglycemia indicates hepatic involvement, weakness and muscle cramps muscle involvement. Hypoglycemia is also the leading neurological symptom in disorders of gluconeogenesis. Disorders of galactose and fructose metabolism are rare, detectable by neonatal screening, and manifest following dietary intake of these sugars. Rare defects within the pentose metabolism constitute a new area of inborn metabolic disorders and may present with neurological symptoms. Treatment of these disorders involves the avoidance of fasting, dietary treatment eliminating specific carbohydrates, and enzyme replacement therapy in individual glycogen storage diseases.GLUT1 deficiency syndrome, a specific disorder of glucose transport into brain, results in global developmental delay, early-onset epilepsy, and a complex movement disorder. Treatment with a high-fat, low-carbohydrate ketogenic diet provides ketones as an alternative fuel to the brain and restores brain energy metabolism. Recently paroxysmal exertion-induced dyskinesia and stomatin-deficient cryohydrocytosis have been identified as an allelic disorder to GLUT1 deficiency equally responding to a ketogenic diet.

  13. Dysregulation of multiple facets of glycogen metabolism in a murine model of Pompe disease.

    Directory of Open Access Journals (Sweden)

    Kristin M Taylor

    Full Text Available Pompe disease, also known as glycogen storage disease (GSD type II, is caused by deficiency of lysosomal acid α-glucosidase (GAA. The resulting glycogen accumulation causes a spectrum of disease severity ranging from a rapidly progressive course that is typically fatal by 1 to 2 years of age to a slower progressive course that causes significant morbidity and early mortality in children and adults. The aim of this study is to better understand the biochemical consequences of glycogen accumulation in the Pompe mouse. We evaluated glycogen metabolism in heart, triceps, quadriceps, and liver from wild type and several strains of GAA(-/- mice. Unexpectedly, we observed that lysosomal glycogen storage correlated with a robust increase in factors that normally promote glycogen biosynthesis. The GAA(-/- mouse strains were found to have elevated glycogen synthase (GS, glycogenin, hexokinase, and glucose-6-phosphate (G-6-P, the allosteric activator of GS. Treating GAA(-/- mice with recombinant human GAA (rhGAA led to a dramatic reduction in the levels of glycogen, GS, glycogenin, and G-6-P. Lysosomal glycogen storage also correlated with a dysregulation of phosphorylase, which normally breaks down cytoplasmic glycogen. Analysis of phosphorylase activity confirmed a previous report that, although phosphorylase protein levels are identical in muscle lysates from wild type and GAA(-/- mice, phosphorylase activity is suppressed in the GAA(-/- mice in the absence of AMP. This reduction in phosphorylase activity likely exacerbates lysosomal glycogen accumulation. If the dysregulation in glycogen metabolism observed in the mouse model of Pompe disease also occurs in Pompe patients, it may contribute to the observed broad spectrum of disease severity.

    Full Text Available Abstract Background The orexigenic effects of cannabinoids are limited by activation of the endocannabinoid degrading enzyme fatty acid amide hydrolase (FAAH. The aim of this study was to analyse whether FAAH alleles are associated with early and late onset obesity. Methods We initially assessed association of five single nucleotide polymorphisms (SNPs in FAAH with early onset extreme obesity in up to 521 German obese children and both parents. SNPs with nominal p-values ≤ 0.1 were subsequently analysed in 235 independent German obesity families. SNPs associated with childhood obesity (p-values ≤ 0.05 were further analysed in 8,491 adult individuals of a population-based cohort (KORA for association with adult obesity. One SNP was further analysed in 985 German obese adults and 588 normal and underweight controls. In parallel, we screened the FAAH coding region for novel sequence variants in 92 extremely obese children using single-stranded-conformation-polymorphism-analysis and denaturing HPLC and assessed the implication of the identified new variants for childhood obesity. Results The trio analysis revealed some evidence for an association of three SNPs in FAAH (rs324420 rs324419 and rs873978 with childhood obesity (two-sided p-values between 0.06 and 0.10. Although analyses of these variants in 235 independent obesity families did not result in statistically significant effects (two-sided p-values between 0.14 and 0.75, the combined analysis of all 603 obesity families supported the idea of an association of two SNPs in FAAH (rs324420 and rs2295632 with early onset extreme obesity (p-values between 0.02 and 0.03. No association was, however, found between these variants and adult obesity. The mutation screen revealed four novel variants, which were not associated with early onset obesity (p > 0.05. Conclusions As we observed some evidence for an association of the FAAH variants rs2295632 rs324420 with early onset but not adult obesity

    Full Text Available BACKGROUND: Early diagnosis of sepsis enables timely resuscitation and antibiotics and prevents subsequent morbidity and mortality. Clinical approaches relying on point-in-time analysis of vital signs or lab values are often insensitive, non-specific and late diagnostic markers of sepsis. Exploring otherwise hidden information within intervals-in-time, heart rate variability (HRV has been documented to be both altered in the presence of sepsis, and correlated with its severity. We hypothesized that by continuously tracking individual patient HRV over time in patients as they develop sepsis, we would demonstrate reduced HRV in association with the onset of sepsis. METHODOLOGY/PRINCIPAL FINDINGS: We monitored heart rate continuously in adult bone marrow transplant (BMT patients (n = 21 beginning a day before their BMT and continuing until recovery or withdrawal (12+/-4 days. We characterized HRV continuously over time with a panel of time, frequency, complexity, and scale-invariant domain techniques. We defined baseline HRV as mean variability for the first 24 h of monitoring and studied individual and population average percentage change (from baseline over time in diverse HRV metrics, in comparison with the time of clinical diagnosis and treatment of sepsis (defined as systemic inflammatory response syndrome along with clinically suspected infection requiring treatment. Of the 21 patients enrolled, 4 patients withdrew, leaving 17 patients who completed the study. Fourteen patients developed sepsis requiring antibiotic therapy, whereas 3 did not. On average, for 12 out of 14 infected patients, a significant (25% reduction prior to the clinical diagnosis and treatment of sepsis was observed in standard deviation, root mean square successive difference, sample and multiscale entropy, fast Fourier transform, detrended fluctuation analysis, and wavelet variability metrics. For infected patients (n = 14, wavelet HRV demonstrated a 25% drop from

    (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) has become useful for the detection and diagnosis of inflammatory conditions, including rheumatic diseases, immunoglobulin (Ig) G4-related disease and giant cell arteritis. However, few articles based on small sample sizes (n = 7) diagnosed as adult-onset Still's disease (AOSD) have been published. The study aim was to observe the reliable characteristics and usefulness of (18)F-FDG PET/CT for the evaluation of consecutive patients with AOSD. Eligible patients were selected from among those who had undergone (18)F-FDG PET/CT between May 2007 and June 2014. Twenty-six consecutive AOSD patients were recruited retrospectively according to criteria set by Yamaguchi et al. All patients underwent evaluation by (18)F-FDG PET/CT. The characteristics and usefulness of (18)F-FDG PET/CT for evaluation of consecutive patients with AOSD were evaluated. All 26 patients had (18)F-FDG-avid lesion(s) related to their particular disease. Diffuse and homogeneous accumulation of (18)F-FDG was seen in the bone marrow (26/26; 100 %; maximum standardized uptake (SUVmax), 2.10-6.73) and spleen (25/26; 96.15 %). The SUVmax of affected lymph nodes was 1.3-9.53 (mean ± SD, 4.12 ± 2.24). The SUVmax and size factors (maximum diameter and areas) of affected lymph nodes were significantly different (P = 0.033 and P = 0.012, respectively). (18)F-FDG PET/CT showed the general distribution of (18)F-FDG accumulation. This factor helped to exclude malignant disease and aided the diagnosis of AOSD (42.3 %) in 11 cases when combined with clinical features and aided decisions regarding appropriate biopsy sites, such as the lymph nodes (n = 9) and bone marrow (n = 13). (18)F-FDG PET/CT is a unique imaging method for the assessment of metabolic activity throughout the body in subjects with AOSD. Characteristics or patterns of AOSD observed on (18)F-FDG PET/CT can be used for the

    Calprotectin is a calcium-binding cytosolic protein, mainly expressed in immune cells, such as neutrophils, monocytes, and macrophages. Our study aimed to evaluate the diagnostic value of calprotectin for adult-onset Still's disease (AOSD), by comparing serum calprotectin concentrations in patients with AOSD (n = 46), rheumatoid arthritis (RA, n = 34), primary Sjögren syndrome (pSS, n = 40), systemic lupus erythematosus (SLE, n = 39), osteoarthritis (OA, n = 20), and healthy controls (HCs, n = 49). Calprotectin concentrations were significantly higher in patients with AOSD (55.26 ± 18.00 ng/ml), compared to patients with RA (39.17 ± 18.90 ng/ml), pSS (35.31 ± 19.47 ng/ml), SLE (32.21 ± 25.01 ng/ml), OA (19.24 ± 10.67 ng/ml), and HCs (8.46 ± 5.17 ng/ml). All the differences were highly significant (p < 0.001). Using receiver-operating characteristic curve, the cut-off value of calprotectin was defined as 45.488 ng/ml, and its sensitivity and specificity for AOSD diagnosis were 63.0 and 80.1%, respectively. The positive rate of calprotectin was significantly higher in AOSD cases compared to patients with other diseases and healthy controls (p < 0.001). Serum calprotectin was positively correlated with ferritin (r = 0.294, p < 0.05), and concentration of hemoglobin was significantly lower in calprotectin-positive patients compared to negative patients in AOSD (103.49 ± 20.21 g/l vs 115.71 ± 15.59 g/l, t = -2.142, p = 0.038). These findings suggest that serum calprotectin may serve as a promising marker for the diagnosis of AOSD and monitor disease activity to a certain extent.

  18. The relationship between childhood conduct disorder and adult antisocial behavior is partially mediated by early-onset alcohol abuse.

    Early-onset alcohol abuse (EOAA) was previously found to both mediate and moderate the effect of childhood conduct disorder (CD) on adult antisocial behavior (ASB) in an American community sample of young adults (Howard, R., Finn, P. R., Gallagher, J., & Jose, P. (2011). Adolescent-onset alcohol abuse exacerbates the influence of childhood conduct disorder on late adolescent and early adult antisocial behavior. Journal of Forensic Psychiatry and Psychology. Advance online publication. doi:10.1080/14789949.2011.641996). This study tested whether this result would generalize to a British forensic sample comprising 100 male forensic patients with confirmed personality disorder. Results confirmed that those in whom EOAA co-occurred with CD showed the highest level of personality pathology, particularly Cluster B traits and antisocial/borderline comorbidity. Those with co-occurring CD with EOAA, compared with those showing only CD, showed more violence in their criminal history and greater recreational drug use. Regression analysis showed that both EOAA and CD predicted adult ASB when covariates were controlled. Further analysis showed that EOAA significantly mediated but did not moderate the effect of CD on ASB. The failure to demonstrate an exacerbating effect of EOAA on the relationship between CD and ASB likely reflects the high prevalence of CD in this forensic sample. Some implications of these findings are discussed.

    Discrete time survival analysis was used to assess the age-specific association of event-related oscillations (EROs) and CHRM2 gene variants on the onset of regular alcohol use and alcohol dependence. The subjects were 2,938 adolescents and young adults ages 12-25. Results showed that the CHRM2 gene variants and ERO risk factors had hazards which varied considerably with age. The bulk of the significant age-specific associations occurred in those whose age of onset was under 16. These associations were concentrated in those subjects who at some time took an illicit drug. These results are consistent with studies which associate greater rates of alcohol dependence among those who begin drinking at an early age. The age specificity of the genetic and neurophysiological factors is consistent with recent studies of adolescent brain development, which locate an interval of heightened vulnerability to substance use disorders in the early to mid teens.

    Full Text Available Abstract Background Although the development of early-onset dementia is a radical and invalidating experience for both patient and family there are hardly any non-pharmacological studies that focus on this group of patients. One type of a non-pharmacological intervention that appears to have a beneficial effect on cognition in older persons without dementia and older persons at risk for dementia is exercise. In view of their younger age early-onset dementia patients may be well able to participate in an exercise program. The main aim of the EXERCISE-ON study is to assess whether exercise slows down the progressive course of the symptoms of dementia. Methods/Design One hundred and fifty patients with early-onset dementia are recruited. After completion of the baseline measurements, participants living within a 50 kilometre radius to one of the rehabilitation centres are randomly assigned to either an aerobic exercise program in a rehabilitation centre or a flexibility and relaxation program in a rehabilitation centre. Both programs are applied three times a week during 3 months. Participants living outside the 50 kilometre radius are included in a feasibility study where participants join in a daily physical activity program set at home making use of pedometers. Measurements take place at baseline (entry of the study, after three months (end of the exercise program and after six months (follow-up. Primary outcomes are cognitive functioning; psychomotor speed and executive functioning; (instrumental activities of daily living, and quality of life. Secondary outcomes include physical, neuropsychological, and rest-activity rhythm measures. Discussion The EXERCISE-ON study is the first study to offer exercise programs to patients with early-onset dementia. We expect this study to supply evidence regarding the effects of exercise on the symptoms of early-onset dementia, influencing quality of life. Trial registration The present study is registered

    Glycogen storage diseases (GSD) are inherited metabolic disorders of glycogen metabolism. Different hormones,including insulin, glucagon, and cortisol regulate the relationship of glycolysis, gluconeogenesis and glycogen synthesis. The overall GSD incidence is estimated 1 case per 20 000-43 000 live births. There are over 12 types and they are classified based on the enzyme deficiency and the affected tissue. Disorders of glycogen degradation may affect primarily the liver, the muscle,or both. Type Ⅰ a involves the liver, kidney and intestine (and Ⅰ b also leukocytes), and the clinical manifestations are hepatomegaly, failure to thrive, hypoglycemia,hyperlactatemia, hyperuricemia and hyperlipidemia. Type Ⅲa involves both the liver and muscle, and Ⅲb solely the liver. The liver symptoms generally improve with age.Type Ⅳ usually presents in the first year of life, with hepatomegaly and growth retardation. The disease in general is progressive to cirrhosis. Type Ⅵ and Ⅸ are a heterogeneous group of diseases caused by a deficiency of the liver phosphorylase and phosphorylase kinase system. There is no hyperuricemia or hyperlactatemia.Type Ⅺ is characterized by hepatic glycogenosis and renal Fanconi syndrome. Type Ⅱ is a prototype of inborn lysosomal storage diseases and involves many organs but primarily the muscle. Types Ⅴ and Ⅶ involve only the muscle.

    The storage and use of glycogen, the main energy reserve in the brain, is a metabolic feature of astrocytes. Glycogen synthesis is regulated by Protein Targeting to Glycogen (PTG), a member of specific glycogen-binding subunits of protein phosphatase-1 (PPP1). It positively regulates glycogen synthesis through de-phosphorylation of both glycogen synthase (activation) and glycogen phosphorylase (inactivation). In cultured astrocytes, PTG mRNA levels were previously shown to be enhanced by the neurotransmitter noradrenaline. To achieve further insight into the role of PTG in the regulation of astrocytic glycogen, its levels of expression were manipulated in primary cultures of mouse cortical astrocytes using adenovirus-mediated overexpression of tagged-PTG or siRNA to downregulate its expression. Infection of astrocytes with adenovirus led to a strong increase in PTG expression and was associated with massive glycogen accumulation (>100 fold), demonstrating that increased PTG expression is sufficient to induce glycogen synthesis and accumulation. In contrast, siRNA-mediated downregulation of PTG resulted in a 2-fold decrease in glycogen levels. Interestingly, PTG downregulation strongly impaired long-term astrocytic glycogen synthesis induced by insulin or noradrenaline. Finally, these effects of PTG downregulation on glycogen metabolism could also be observed in cultured astrocytes isolated from PTG-KO mice. Collectively, these observations point to a major role of PTG in the regulation of glycogen synthesis in astrocytes and indicate that conditions leading to changes in PTG expression will directly impact glycogen levels in this cell type.

    The newly published Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) elevates the threshold of the ADHD age-of-onset criterion from 7 to 12 years. This study evaluated the quality of life and functional impairment of adults with ADHD who had symptoms onset by or after 7 years and examined the mediation effect of family function and anxiety/depression symptoms between ADHD diagnosis and quality of life and functional impairment. We assessed 189 adults with ADHD and 153 non-ADHD controls by psychiatric interview and self-administered reports on the Adult ADHD Quality of Life Scale, Weiss Functional Impairment Rating Scale, Family APGAR, and Adult Self Report Inventory-4. The ADHD group was divided into early-onset ADHD (onset ADHD (onset between 7 and 12 years, n=42). The mediation analysis was conducted to verify the mediating factors from ADHD to functional impairment and quality of life. The late-onset ADHD had more severe functional impairment at work and poorer family support than early-onset ADHD while they had comparable impairment at other domains. Less perceived family support and current anxiety/depressive symptoms partially mediated the link between ADHD diagnosis and quality of life/functional impairment both in early- and late-onset ADHD. Our data support decreased quality of life and increased functional impairment in adult ADHD, regardless of age of onset, and these adverse outcomes may be mediated by family support and anxiety/depression at adulthood. Our findings also imply that the new DSM-5 ADHD criteria do not over-include individuals without impairment.

    Adult onset Still’s disease is uncommon in middle-aged and elderly individuals and can rarely present with shock; shock is usually associated with disseminated intravascular coagulation, multiorgan dysfunction syndrome or acute respiratory distress syndrome. We report a post-menopausal woman with arthritis, fever, pneumonitis and hypotension which was managed as septic shock. Steroids were inadvertently missed during the second day of hospitalization in the intensive care unit. Persistence of hypotension on inotropes, with normal renal, hepatic and neurological function and recurrence of fever when steroids were skipped, led to suspicion of an inflammatory disorder. A diagnosis of Still’s disease may be entertained in postmenopausal women with polyarthritis, rash, and fever with leukocytosis. Sepsis is mimicked, and multiple antibiotics use is common before the diagnosis of such an entity is made. Shock is rare in adult onset Still’s disease and is not necessarily associated with disseminated intravascular coagulation, acute respiratory distress syndrome, or multiorgan dysfunction.

    This study aims to answer the research question of "Are early onset aging conditions correlated to daily activity functions in youth and adults with Down syndrome (DS)?" A cross-sectional survey was employed to recruit 216 individuals with DS over 15 years of age in the analyses. A structured questionnaire included demographic data, brief self-reported aging conditions, Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) and activity of daily living (ADL) scales were completed by the primary caregivers who were well-suited for providing information on the functioning conditions of the DS individuals. Results showed that the most five frequent aging conditions (sometimes, usually and always) included frailty (20.2%), vision problem (15.8%), loss of language ability (15.3%), sleep problem (14.9%) and memory impairment (14.5%). Other onset aging conditions included more chronic diseases (13.9%), hearing loss (13%), chewing ability and tooth loss (12.5%), incontinence (11.1%), depressive syndrome (7.7%), falls and gait disorder (7.2%), loss of taste and smell (7.2%). The data also showed scores of DSQIID, onset aging conditions and ADL has significant relationships each other in Pearson's correlation tests. Finally, multiple linear regression analyses indicated onset aging conditions (β=-0.735, p<0.001) can significantly predicted the variation in ADL scores after adjusting other factors (R(2)=0.381). This study suggests that the authority should initiate early intervention programs aim to improve healthy aging and ADL functions for people with DS.

    Third-generation cephalosporins (3GCs) [ceftriaxone (CRO) and cefotaxime (CTX)] have remarkable potency against Enterobacteriaceae and are commonly prescribed for the treatment of community-onset bacteraemia. However, clinical evidence supporting the updated interpretive criteria of the Clinical and Laboratory Standards Institute (CLSI) is limited. Adults with community-onset monomicrobial Enterobacteriaceae bacteraemia treated empirically with CRO or CTX were recruited. Clinical information was collected from medical records and CTX MICs were determined using the broth microdilution method. Eligible patients (n=409) were categorised into de-escalation (260; 63.6%), no switch (115; 28.1%) and escalation (34; 8.3%) groups according to the type of definitive antibiotics. Multivariate regression revealed five independent predictors of 28-day mortality: fatal co-morbidities based on McCabe classification [odds ratio (OR)=19.96; P<0.001]; high Pitt bacteraemia score (≥4) at bacteraemia onset (OR=13.91; P<0.001); bacteraemia because of pneumonia (OR=5.45; P=0.007); de-escalation after empirical therapy (OR=0.28; P=0.03); and isolates with a CTX MIC≤1mg/L (OR=0.17; P=0.02). Of note, isolates with a CTX MIC≤8mg/L (indicated as susceptible by previous CLSI breakpoints) were not associated with mortality. Furthermore, clinical failure and 28-day mortality rates had a tendency to increase with increasing CTX MIC (γ=1.00; P=0.01). Conclusively, focusing on patients with community-onset Enterobacteriaceae bacteraemia receiving empirical 3GC therapy, the present study provides clinically critical evidence to validate the proposed reduction in the susceptibility breakpoint of CTX to MIC≤1mg/L.

    Objectives Bipolar disorder (BD) is a severe mental illness with high healthcare costs and poor outcomes. Increasing numbers of youths are diagnosed with BD, and many adults with BD report their symptoms started in childhood, suggesting BD can be a developmental disorder. Studies advancing our understanding of BD have shown alterations in facial emotion recognition in both children and adults with BD compared to healthy comparison (HC) participants, but none have evaluated the development of these deficits. To address this, we examined the effect of age on facial emotion recognition in a sample that included children and adults with confirmed childhood-onset type-I BD, with the adults having been diagnosed and followed since childhood by the Course and Outcome in Bipolar Youth study. Methods Using the Diagnostic Analysis of Non-Verbal Accuracy, we compared facial emotion recognition errors among participants with BD (n = 66; ages 7–26 years) and HC participants (n = 87; ages 7–25 years). Complementary analyses investigated errors for child and adult faces. Results A significant diagnosis-by-age interaction indicated that younger BD participants performed worse than expected relative to HC participants their own age. The deficits occurred for both child and adult faces and were particularly strong for angry child faces, which were most often mistaken as sad. Our results were not influenced by medications, comorbidities/substance use, or mood state/global functioning. Conclusions Younger individuals with BD are worse than their peers at this important social skill. This deficit may be an important developmentally salient treatment target, i.e., for cognitive remediation to improve BD youths’ emotion recognition abilities. PMID:25951752

    Cirrhotic patients often demonstrate glucose intolerance, one of the possible causes being a decreased glycogen-synthesizing capacity of the liver. At the same time, information about the rates of glycogen synthesis in the cirrhotic liver is scanty and contradictory. We studied the dynamics of glycogen accumulation and the activity of glycogen synthase (GS) and glycogen phosphorylase (GP) in the course of 120min after per os administration of glucose or fructose to fasted rats with CCl4-cirrhosis or fasted normal rats. Blood serum and liver pieces were sampled for examinations. In the normal rat liver administration of glucose/fructose initiated a fast accumulation of glycogen, while in the cirrhotic liver glycogen was accumulated with a 20min delay and at a lower rate. In the normal liver GS activity rose sharply and GPa activity dropped in the beginning of glycogen synthesis, but 60min later a high synthesis rate was sustained at the background of a high GS and GPa activity. Contrariwise, in the cirrhotic liver glycogen was accumulated at the background of a decreased GS activity and a low GPa activity. Refeeding with fructose resulted in a faster increase in the GS activity in both the normal and the cirrhotic liver than refeeding with glucose. To conclude, the rate of glycogen synthesis in the cirrhotic liver is lower than in the normal one, the difference being probably associated with a low GS activity.

    Glycogen synthase is a rate-limiting enzyme in the biosynthesis of glycogen and has an essential role in glucose homeostasis. The three-dimensional structures of yeast glycogen synthase (Gsy2p) complexed with maltooctaose identified four conserved maltodextrin-binding sites distributed across the surface of the enzyme. Site-1 is positioned on the N-terminal domain, site-2 and site-3 are present on the C-terminal domain, and site-4 is located in an interdomain cleft adjacent to the active site. Mutation of these surface sites decreased glycogen binding and catalytic efficiency toward glycogen. Mutations within site-1 and site-2 reduced the V{sub max}/S{sub 0.5} for glycogen by 40- and 70-fold, respectively. Combined mutation of site-1 and site-2 decreased the V{sub max}/S{sub 0.5} for glycogen by >3000-fold. Consistent with the in vitro data, glycogen accumulation in glycogen synthase-deficient yeast cells ({Delta}gsy1-gsy2) transformed with the site-1, site-2, combined site-1/site-2, or site-4 mutant form of Gsy2p was decreased by up to 40-fold. In contrast to the glycogen results, the ability to utilize maltooctaose as an in vitro substrate was unaffected in the site-2 mutant, moderately affected in the site-1 mutant, and almost completely abolished in the site-4 mutant. These data show that the ability to utilize maltooctaose as a substrate can be independent of the ability to utilize glycogen. Our data support the hypothesis that site-1 and site-2 provide a 'toehold mechanism,' keeping glycogen synthase tightly associated with the glycogen particle, whereas site-4 is more closely associated with positioning of the nonreducing end during catalysis.

    Hereditary spinocerebellar ataxia (SCA) is a relatively common disorder in the Western Cape region of South Africa. At present there are no genetic markers available for prenatal or presymptomatic diagnosis. A large kindred of mixed ancestry with late onset SCA was studied in which the disorder segregated in an autosomal dominant fashion. HLA typing was undertaken on 44 family members, and the HLA haplotypes were assigned on the basis of segregation. The LIPED computer program, with a correction factor allowing for the age of onset, was used to analyze the pedigree for linkage to HLA. Of 22 individuals in whom disease status could be definitely assessed, only one recombinant between HLA and the SCA locus occurred. The lod score reached a maximum of 4.13 at a recombination fraction of 0.05, indicating the odds to be approximately 13,500 to 1 in favor of linkage between HLA and the putative disease allele for SCA. A possible recombination within the HLA region suggested that the disease allele lies telomeric of the HLA region. In view of the recent demonstration of tight linkage between SCA1 and D6S89, however, HLA should not be used for presymptomatic diagnosis or genetic counselling.

    Full Text Available Anna Kelemen1, Péter Halász21National Institute of Neurosciences, Epilepsy Center, Budapest, Hungary; 2Faculty of Information Technology, Pázmány Péter Catholic University, Budapest, Hungary Abstract: Lacosamide is a newly registered antiepileptic drug with dual mechanisms of action. It selectively enhances slow inactivation of voltage-gated sodium channels, resulting in stabilization of hyperexcitable neuronal membranes and inhibition of repetitive neuronal firing. It also binds to a collapsing-response mediator protein-2, CRMP2. Lacosamide has a favorable pharmacokinetic profile; is rapidly and completely absorbed, has a relatively long elimination half-life of 13 hours which allows twice-daily administration, linear pharmacokinetics, and has low potential for drug interactions and renal elimination. Both oral and intravenous formulations of lacosamide are being developed. In placebo-controlled clinical trials, lacosamide was effective in seizure reduction as adjunctive therapy in patients with uncontrolled partial-onset seizures. Lacosamide was generally well tolerated. The most frequently reported adverse events in placebo-controlled trials were dizziness, headache, nausea, and diplopia. Intravenous lacosamide has a comparably good safety profile.Keywords: lacosamide, epilepsy, partial onset seizures

    Glycogen provides an important glucose reservoir in the brain since the concentration of glucosyl units stored in glycogen is several fold higher than free glucose available in brain tissue. We have previously reported 3–4 µmol/g brain glycogen content using in vivo 13C magnetic resonance spectroscopy (MRS) in conjunction with [1-13C]glucose administration in healthy humans, while higher levels were reported in the rodent brain. Due to the slow turnover of bulk brain glycogen in humans, complete turnover of the glycogen pool, estimated to take 3–5 days, was not observed in these prior studies. In an attempt to reach complete turnover and thereby steady state 13C labeling in glycogen, here we administered [1-13C]glucose to healthy volunteers for 80 hours. To eliminate any net glycogen synthesis during this period and thereby achieve an accurate estimate of glycogen concentration, volunteers were maintained at euglycemic blood glucose levels during [1-13C]glucose administration and 13C-glycogen levels in the occipital lobe were measured by 13C MRS approximately every 12 hours. Finally, we fitted the data with a biophysical model that was recently developed to take into account the tiered structure of the glycogen molecule and additionally incorporated blood glucose levels and isotopic enrichments as input function in the model. We obtained excellent fits of the model to the 13C-glycogen data, and glycogen content in the healthy human brain tissue was found to be 7.8 ± 0.3 µmol/g, a value substantially higher than previous estimates of glycogen content in the human brain.

    The purpose of this study was to evaluate the effects of early-life exercise on adult physical activity (wheel running, home-cage activity), body mass, food consumption, and circulating leptin levels in males from four replicate lines of mice selectively bred for high voluntary wheel running (High Runner or HR) and their four non-selected control (C) lines. Half of the mice were given wheel access shortly after weaning for three consecutive weeks. Wheel access was then removed for 52 days, followed by two weeks of adult wheel access for all mice. A blood sample taken prior to adult wheel testing was analyzed for circulating leptin concentration. Early-life wheel access significantly increased adult voluntary exercise on wheels during the first week of the second period of wheel access, for both HR and C mice, and HR ran more than C mice. During this same time period, activity in the home cages was not affected by early-age wheel access, and did not differ statistically between HR and C mice. Throughout the study, all mice with early wheel access had lower body masses than their sedentary counterparts, and HR mice had lower body masses than C mice. With wheel access, HR mice also ate significantly more than C mice. Early-life wheel access increased plasma leptin levels (adjusted statistically for fat-pad mass as a covariate) in C mice, but decreased them in HR mice. At sacrifice, early-life exercise had no statistically significant effects on visceral fat pad, heart (ventricle), liver or spleen masses (all adjusted statistically for variation in body mass). Results support the hypothesis that early-age exercise in mice can have at least transitory positive effects on adult levels of voluntary exercise, in addition to reducing body mass, and may be relevant for the public policy debates concerning the importance of physical education for children.

  5. ATP1A3 Mutation in Adult Rapid-Onset Ataxia.

    Full Text Available A 21-year old male presented with ataxia and dysarthria that had appeared over a period of months. Exome sequencing identified a de novo missense variant in ATP1A3, the gene encoding the α3 subunit of Na,K-ATPase. Several lines of evidence suggest that the variant is causative. ATP1A3 mutations can cause rapid-onset dystonia-parkinsonism (RDP with a similar age and speed of onset, as well as severe diseases of infancy. The patient's ATP1A3 p.Gly316Ser mutation was validated in the laboratory by the impaired ability of the expressed protein to support the growth of cultured cells. In a crystal structure of Na,K-ATPase, the mutated amino acid was directly apposed to a different amino acid mutated in RDP. Clinical evaluation showed that the patient had many characteristics of RDP, however he had minimal fixed dystonia, a defining symptom of RDP. Successive magnetic resonance imaging (MRI revealed progressive cerebellar atrophy, explaining the ataxia. The absence of dystonia in the presence of other RDP symptoms corroborates other evidence that the cerebellum contributes importantly to dystonia pathophysiology. We discuss the possibility that a second de novo variant, in ubiquilin 4 (UBQLN4, a ubiquitin pathway component, contributed to the cerebellar neurodegenerative phenotype and differentiated the disease from other manifestations of ATP1A3 mutations. We also show that a homozygous variant in GPRIN1 (G protein-regulated inducer of neurite outgrowth 1 deletes a motif with multiple copies and is unlikely to be causative.

    Several neurological variables have been investigated as premorbid biomarkers of vulnerability for schizophrenia and other related disorders. The current study examined whether childhood dyspraxia predicted later adult nonaffective-psychosis-spectrum disorders. From a standardized neurological examination performed with children (aged 10-13) at genetic high risk of schizophrenia and controls, several measures of dyspraxia were used to create a scale composed of face/head dyspraxia, oral articulation, ideomotor dyspraxia (clumsiness), and dressing dyspraxia (n = 244). Multinomial logistic regression showed higher scores on the dyspraxia scale predict nonaffective-psychosis-spectrum disorders relative to other psychiatric disorders and no mental illness outcomes, even after controlling for genetic risk, χ2 (4, 244) = 18.61, p dyspraxia in childhood (reflecting abnormalities spanning functionally distinct brain networks) specifically predict adult nonaffective-psychosis-spectrum disorders are consistent with a theory of abnormal connectivity, and they highlight a marked early-stage vulnerability in the pathophysiology of nonaffective-psychosis-spectrum disorders.

    Cystic hygroma is a benign congenital malformation of the lymphatic system that occurs in infant or children younger than 2 years of age. Although cystic hygroma is well recognized in pediatric practice, it seldom presents de novo in adulthood. These are commonly present in head and neck but can be present anywhere. Cystic hygroma is very rare in adults, but it should be considered in the differential diagnosis of adult neck swellings. Patients presenting with a painless, soft, fluctuant, and enlarging neck mass should have a careful history and physical examination along with radiological imaging to assist with diagnosis. Surgical intervention is the treatment of choice for this rare condition. Here, we are reporting a case of cystic hygroma in a 32-year-old male patient in the neck region. The objectives of this case report are to discuss the clinical presentation, diagnosis, histopathological findings and management of this malformation.

    Using data from the São Paulo Megacity Mental Health Survey and logistic regression models, we studied how childhood neglect, physical abuse, sexual abuse, and family violence were related to adult hypertension and heart disease. After adjustment for sociodemographic factors, child physical abuse was associated with hypertension and heart disease, whereas family violence was associated with hypertension. Efforts to curb child physical abuse could potentially reduce subsequent hypertension and...

    Full Text Available The relationship of elevated depression risk recently discovered among adult persons raised by same-sex parents with possible precipitating conditions in childhood has not previously been acknowledged. This study tests whether such inattention is supportable. Logistic regression based risk ratios were estimated from longitudinal measures of mental health outcomes observed in three waves (at ages 15, 22, and 28 of the US National Survey of Adolescent to Adult Health (n=15,701. At age 28, the adults raised by same-sex parents were at over twice the risk of depression (CES-D: risk ratio 2.6, 95% CI 1.4–4.6 as persons raised by man-woman parents. These findings should be interpreted with caution. Elevated risk was associated with imbalanced parental closeness and parental child abuse in family of origin; depression, suicidality, and anxiety at age 15; and stigma and obesity. More research and policy attention to potentially problematic conditions for children with same-sex parents appears warranted.

  13. Recurrent adult-onset hypophyseal Langerhans cell histiocytosis after radiotherapy: a case report

    Full Text Available Abstract Introduction Langerhans cell histiocytosis is a rare disease within the adult population, with very few cases reported as solitary hypophyseal lesions in adults. Of the reported cases, most have been treated successfully with surgery, radiotherapy, and/or chemotherapy. Radiotherapy has been thought to be curative at the relatively low dose of 20Gy. Here we report a case of recurrent hypophyseal Langerhans cell histiocytosis 9 months after radiotherapy with an interval period of symptomatic and radiographic response to therapy. Case presentation A 50-year-old Caucasian woman who had headaches, memory difficulties, and diabetes insipidus was found to have a 2.5cm suprasellar mass. Langerhans cell histiocytosis was diagnosed following stereotactic brain biopsy. Further workup revealed no other lesions. Initial radiation treatment succeeded in shrinking the tumor and relieving clinical symptoms temporarily; however, growth and recurrence of clinical symptoms was noted at 9 months. Re-irradiation was well tolerated and the patient had no acute side effects. Conclusion Isolated hypophyseal involvement by Langerhans cell histiocytosis in adults is a unique presentation of a rare disease. Although radiotherapy doses as low as 20Gy have been reported to offer control, this case demonstrates that higher doses may be warranted to ensure tumor control. With modern imaging and radiotherapy techniques higher doses should offer little increased more durable risk to surrounding critical structures.

    Children with special health care needs born today have a 90% chance of surviving into adulthood, making their transition to adult systems of care an issue that will affect almost all physicians. However, many adult generalists and specialists are not familiar with the management of chronic diseases that begin in childhood. While the public health system has made transition to appropriate adult care a priority, and many specialty organizations have endorsed this concept, there are no published studies addressing how the concept of transition can be taught to medical students or residents. The authors describe a one-week course for medical students, begun in 2001 at their institution, that addresses the transition for youth with special health care needs, emphasizing patient and family-centered care, cultural competence, and decision making in end-of-life issues. Cystic fibrosis, a common genetic disease with increasing life expectancy, is used as the model for the course. Involvement of interdisciplinary faculty, interviews with youth with special health care needs and family caregivers, readings from academic and nonacademic literature, and group discussions are presented as teaching methods. Key insights based on experience with the course are the need to include the voices of patients and families, the use of faculty from various professions and specialties to model interdisciplinary care, and the insight that problems specific to transition offer into contemporary health care financing. Future studies should measure the impact of such courses on students' knowledge of transition issues, and determine essential information required for physicians in practice.

  15. Congenital and prolonged adult-onset deafness cause distinct degradations in neural ITD coding with bilateral cochlear implants.

    Bilateral cochlear implant (CI) users perform poorly on tasks involving interaural time differences (ITD), which are critical for sound localization and speech reception in noise by normal-hearing listeners. ITD perception with bilateral CI is influenced by age at onset of deafness and duration of deafness. We previously showed that ITD coding in the auditory midbrain is degraded in congenitally deaf white cats (DWC) compared to acutely deafened cats (ADC) with normal auditory development (Hancock et al., J. Neurosci, 30:14068). To determine the relative importance of early onset of deafness and prolonged duration of deafness for abnormal ITD coding in DWC, we recorded from single units in the inferior colliculus of cats deafened as adults 6 months prior to experimentation (long-term deafened cats, LTDC) and compared neural ITD coding between the three deafness models. The incidence of ITD-sensitive neurons was similar in both groups with normal auditory development (LTDC and ADC), but significantly diminished in DWC. In contrast, both groups that experienced prolonged deafness (LTDC and DWC) had broad distributions of best ITDs around the midline, unlike the more focused distributions biased toward contralateral-leading ITDs present in both ADC and normal-hearing animals. The lack of contralateral bias in LTDC and DWC results in reduced sensitivity to changes in ITD within the natural range. The finding that early onset of deafness more severely degrades neural ITD coding than prolonged duration of deafness argues for the importance of fitting deaf children with sound processors that provide reliable ITD cues at an early age.

    Langerhans cell histiocytosis (LCH) is characterized by the clonal proliferation of Langerhans cells; it is categorized as a single-system disease with single or multifocal lesions, and as a multi-system disease with or without the risk of organ involvement. Although the skin is not categorized as a risk organ, the precise diagnosis of skin lesions is necessary to determine the protocol for the treatment of LCH. In this report, we describe a 28-year-old Japanese man with adult onset of BRAFV600E-mutated LCH with cutaneous involvement successfully diagnosed by immunohistochemical staining. Our report suggests that immunohistochemical staining for the BRAFV600E gene could be a diagnostic tool to determine the clinical type of LCH. PMID:26500535

    A 45-year-old hypertensive Japanese woman presented with epigastric pain on inspiration, fever, complete atrioventricular block and polyarthritis. Her antistreptolysin O levels were markedly elevated. A diagnosis of rheumatic fever was made according to the modified Jones criteria. She was prescribed loxoprofen sodium, which was partially effective for her extracardiac clinical symptoms. However, she had syncope due to complete atrioventricular block with asystole longer than 10 seconds. Consequently, we implanted a permanent pacemaker. Although we prescribed prednisolone, the efficacy of which was limited for the patient's conduction disturbance, the complete atrioventricular block persisted. In our systematic review of 12 similar cases, the duration of complete heart block was always transient and there was no case requiring a permanent pacemaker. We thus encountered a very rare case of adult-onset acute rheumatic fever with persistent complete atrioventricular block necessitating permanent pacemaker implantation.

    We report the case of a 42-year-old woman with a slowly progressive cerebellar syndrome. In contrast to a relatively mild clinical presentation, the magnetic resonance imaging (MRI) showed extensive leukencephalopathy with cystic degeneration. Initially primary progressive multiple sclerosis (PPMS) was suspected. Additional diffusion-weighted imaging revealed restricted diffusion in the white matter lesions with a reduced apparent diffusion coefficient. Genetic testing showed vanishing white matter disease (VWM) with c.260C>T EIF2B3 mutation. In conclusion, in cases with relatively mild symptoms and extensive white matter lesions, adult-onset VWM should be considered as differential diagnosis of PPMS and diffusion-weighted imaging may be helpful to identify suspected cases.

    Cyanobacteria accumulate glycogen as a major intracellular carbon and energy storage during photosynthesis. Recent developments in research have highlighted complex mechanisms of glycogen metabolism, including the diel cycle of biosynthesis and catabolism, redox regulation, and the involvement...... of non-coding RNA. At the same time, efforts are being made to redirect carbon from glycogen to desirable products in genetically engineered cyanobacteria to enhance product yields. Several methods are used to determine the glycogen contents in cyanobacteria, with variable accuracies and technical...... complexities. Here, we provide a detailed protocol for the reliable determination of the glycogen content in cyanobacteria that can be performed in a standard life science laboratory. The protocol entails the selective precipitation of glycogen from the cell lysate and the enzymatic depolymerization...

    The Hyperornithinemia-Hyperammonemia-Homocitrullinuria (HHH) syndrome is a disorder of the urea cycle and ornithine degradation pathway caused by mutations in the mitochondrial ornithine transporter, ORNT1 (SLC25A15). In general, the majority of patients with HHH syndrome come to medical attention during infancy or early school years with symptoms such as learning disabilities, changes in cognitive development, spasticity, or liver dysfunction. In this report, we describe a 35-year-old male of Indian descent who was diagnosed with HHH syndrome after he presented to the emergency room with gastroenteritis, disorientation, and slurred speech. Molecular analysis revealed that this patient was heterozygous for two ORNT1 mutations, p.[Gly220Arg(+)Arg275X] (c.[658G>A(+)823C>T]) that had been previously reported in homozygous probands who presented during the first year of life. Cellular studies revealed that the ORNT1 p.Gly220Arg mutation was nonfunctional but targeted to the mitochondria. Given that this patient was a successful college graduate on a vegetarian diet without a prior history of learning or neurological impairment, additional factors such as gene redundancy, environmental, and epigenetic factors may have contributed to the delay in onset of presentation and lack of any previous symptoms. To the best of our knowledge, this is the first reported case of an adult-onset HHH syndrome presentation without a prior history of neurological or cognitive deficiency.

    Mutations in the αB-crystallin gene (CRYAB) have been reported in desmin-related myopathies, with or without cardiac involvement. Mutations in this gene have also been documented in large multi-generation families with autosomal dominant congenital posterior pole cataract (CPPC). In these congenital cataract families no cardiac or muscular phenotype was reported. This report describes a family with an unusual read-through mutation in CRYAB, leading to the elongation of the normal αB-crystallin protein with 19 amino acid residues. Affected family members combine a CPPC with an adult onset dilated cardiomyopathy (DCM), thereby expanding the αB-crystallinopathy phenotype. Repolarisation abnormalities preceded the onset of cardiomyopathy and were already present in childhood. No skeletal myopathy was observed. This report illustrates that congenital cataract can be a prelude to more severe disease even outside the context of inborn errors of metabolism. The identification of a CRYAB mutation in this family supports the notion that mutations in this gene are a rare cause of genetically determined DCM. The combined congenital cataract/cardiomyopathy phenotype adds to our understanding of the complex phenotypic spectrum of αB-crystallinopathies.

  3. Acute onset sleep apnea with severe transient hyperglycemia in young adult: the diagnostic dilemma and management controversy

    Full Text Available Sleep disordered breathing and obstructive sleep apnea are frequently associated with hyperglycemic disorders. The common pathophysiological factors that link these disorders have been a matter of debate and current research. Abdominal adiposity and high body mass index are considered to predispose individuals to early onset of type 2 diabetes and related metabolic disorders. A young adult presenting with symptoms of obstructive sleep apnea often poses a diagnostic challenge for clinicians especially when multiple risk factors coexist. It is essential to establish the exact diagnosis so that specific treatment can be initiated. The role of a non-aggressive approach in management of severe hyperglycemic conditions has been doubted. We report a case of a 33 year old man presenting to the respiratory outdoor clinic for recent onset loud snoring and increased daytime sleepiness. Routine biochemistry reports revealed hyperlipidemia and severe hyperglycemia. The patient was ambulatory and stable throughout. The subsequent investigations identified multiple stressors and the possibility of a single cause was analysed. A rapid glycemic control and amelioration of symptoms were observed based on consistent monitoring and a conservative clinical approach. The key findings and relevant review of literature are discussed in this article. [Int J Res Med Sci 2013; 1(2.000: 168-172

    The clinical expression of systemic lupus erythematosus (SLE) is influenced by genetic and environmental factors and therefore varies between ethnicities. Information on the epidemiology of SLE in Brazil is scarce and practically limited to studies conducted in socioeconomically developed regions (South and Southeast). The objective of this study was to describe the clinical and immunological aspects and outcome of a cohort of patients with SLE treated at a university hospital in northeastern Brazil and compare patterns related to age at onset: childhood (cSLE), adult (aSLE), and late (lSLE). A random sample of 414 records (women: 93.5%) were reviewed. The mean age at SLE onset and the mean disease duration were 28.9 ± 10.9 years and 10.2 ± 6.6 years, respectively. Most patients had aSLE (n = 338; 81.6%), followed by cSLE (n = 60; 14.5%) and lSLE (n = 16; 3.9%). The female/male ratio was 6.5:1 in cSLE and 16.8:1 in aSLE; in lSLE, all patients were female (p = 0.05). During follow-up, the cSLE group presented higher rates of nephritis (70% vs. 52.9% vs. 12.5%; p = 0.0001) and leuko/lymphopenia (61.7% vs. 43.8% vs. 56.2%; p = 0.02). No significant differences were found for anti-dsDNA, anti-Sm, and antiphospholipid antibodies. Treatment with immunosuppressants was significantly more common, and higher doses of prednisone were used, in cSLE. The prevalence of cardiovascular diseases were more frequent in lSLE (p = 0.03). No significant differences were found between the three groups with regard to mean damage accrual (SDI), remission, and mortality. Although cSLE presented higher rates of nephritis and leuko/lymphopenia, more frequent use of immunosuppressants and higher prednisone doses than aSLE and lSLE, the three groups did not differ significantly with regard to damage accrual, remission, and mortality. © The Author(s) 2015.

  5. Simultaneous POMC gene transfer to hypothalamus and brainstem increases physical activity, lipolysis and reduces adult-onset obesity.

    Pro-opiomelanocortin (POMC) neurons are identified in two brain sites, the arcuate nucleus of the hypothalamus and nucleus of the solitary tract (NTS) in brainstem. Earlier pharmacological and POMC gene transfer studies demonstrate that melanocortin activation in either site alone improves insulin sensitivity and reduces obesity. The present study, for the first time, investigated the long-term efficacy of POMC gene transfer concurrently into both sites in the regulation of energy metabolism in aged F344xBN rats bearing adult-onset obesity. Pair feeding was included to reveal food-independent POMC impact on energy expenditure. We introduced adeno-associated virus encoding either POMC or green fluorescence protein to the two brain areas in 22-month-old rats, then recorded food intake and body weight, assessed oxygen consumption, serum leptin, insulin and glucose, tested voluntary wheel running, analysed POMC expression, and examined fat metabolism in brown and white adipose tissues. POMC mRNA was significantly increased in both the hypothalamus and NTS region at termination. Relative to pair feeding, POMC caused sustained weight reduction and additional fat loss, lowered fasting insulin and glucose, and augmented white fat hormone-sensitive lipase activity and brown fat uncoupling protein 1 level. By wheel running assessment, the POMC animals ran twice the distance as the Control or pair-fed rats. Thus, the dual-site POMC treatment ameliorated adult-onset obesity effectively, involving a moderate hypophagia lasting ∼60 days, enhanced lipolysis and thermogenesis, and increased physical activity in the form of voluntary wheel running. The latter finding provides a clue for countering age-related decline in physical activity.

    We examined the role of sarcopenic obesity as a risk factor for new-onset depressive symptoms over 6-year follow-up in a large sample of older adults. The sample comprised 3862 community dwelling participants (1779 men, 2083 women; mean age 64.6±8.3 years) without depressive symptoms at baseline, recruited from the English Longitudinal Study of Ageing. At baseline and 4-year follow-up, handgrip strength (kg) of the dominant hand was assessed using a hand-held dynamometer, as a measure of sarcopenia. The outcome was new onset depressive symptoms at 6-year follow-up, defined as a score of ⩾4 on the 8-item Centre of Epidemiological Studies Depression scale. Sarcopenic obesity was defined as obese individuals (body mass index ⩾30 kg m(-)(2)) in the lowest tertile of sex-specific grip strength (obese adults in the lowest tertile of handgrip strength (odds ratio (OR), 1.79, 95% confidence interval (CI), 1.10, 2.89) compared with non-obese individuals with high handgrip strength. Participants who were obese at baseline and had a decrease of more than 1 s.d. in grip strength over 4-year follow-up were at greatest risk of depressive symptoms (OR=1.97, 95% CI, 1.22, 3.17) compared with non-obese with stable grip strength. A reduction in grip strength was associated with higher risk of depressive symptoms in obese participants only, suggesting that sarcopenic obesity is a risk factor for depressive symptoms.

  7. Temporal discrimination thresholds in adult-onset primary torsion dystonia: an analysis by task type and by dystonia phenotype.

    Adult-onset primary torsion dystonia (AOPTD) is an autosomal dominant disorder with markedly reduced penetrance. Sensory abnormalities are present in AOPTD and also in unaffected relatives, possibly indicating non-manifesting gene carriage (acting as an endophenotype). The temporal discrimination threshold (TDT) is the shortest time interval at which two stimuli are detected to be asynchronous. We aimed to compare the sensitivity and specificity of three different TDT tasks (visual, tactile and mixed\\/visual-tactile). We also aimed to examine the sensitivity of TDTs in different AOPTD phenotypes. To examine tasks, we tested TDT in 41 patients and 51 controls using visual (2 lights), tactile (non-painful electrical stimulation) and mixed (1 light, 1 electrical) stimuli. To investigate phenotypes, we examined 71 AOPTD patients (37 cervical dystonia, 14 writer\\'s cramp, 9 blepharospasm, 11 spasmodic dysphonia) and 8 musician\\'s dystonia patients. The upper limit of normal was defined as control mean +2.5 SD. In dystonia patients, the visual task detected abnormalities in 35\\/41 (85%), the tactile task in 35\\/41 (85%) and the mixed task in 26\\/41 (63%); the mixed task was less sensitive than the other two (p = 0.04). Specificity was 100% for the visual and tactile tasks. Abnormal TDTs were found in 36 of 37 (97.3%) cervical dystonia, 12 of 14 (85.7%) writer\\'s cramp, 8 of 9 (88.8%) blepharospasm, 10 of 11 (90.1%) spasmodic dysphonia patients and 5 of 8 (62.5%) musicians. The visual and tactile tasks were found to be more sensitive than the mixed task. Temporal discrimination threshold results were comparable across common adult-onset primary torsion dystonia phenotypes, with lower sensitivity in the musicians.

    The transition of adult patients with childhood-onset chronic diseases (APCCD) from pediatric to adult health-care systems has recently received worldwide attention. However, Japan is lagging behind European countries and North America as this concept of health-care transition was introduced only 10 years ago. In Japan, before the introduction of this concept, APCCD were referred to as "carryover patients," who were often considered a burden in pediatric practice. In the late 1990s, groups composed of pediatric nephrologists, developmental and behavioral pediatricians, pediatric nurses, and special education teachers researching the quality of life of adult patients with chronic kidney disease began to discuss the physical and psychosocial problems of APCCD. In 2006, a group of pediatricians first introduced the term "transition" in a Japanese journal. By 2010, a group of adolescent nurses had begun a specialized training program aimed at supporting patients during the transitional period. In 2013, the Ministry of Health, Labour and Welfare in Japan convened a research committee, focusing on issues related to social, educational, and medical support for APCCD, and the Japan Pediatric Society established a committee for the health-care transition of APCCD and summarized their statements. Moreover, in 2013, the Tokyo Metropolitan Children's Medical Center initiated ambulatory services for APCCD managed by specialized nurses. The concept of health-care transition has rapidly spread over these past 10 years. The purpose of this article is to describe how this concept of health-care transition has advanced in Japan, such that APCCD now experience a positive pediatric to adult health-care transition.

    The observation that cancer often arises at sites of chronic inflammation has prompted the idea that carcinogenesis and inflammation are deeply interwoven. In fact, the current literature highlights a role for chronic inflammation in virtually all the steps of carcinogenesis, including tumor initiation, promotion and progression. The aim of the present article is to review the current literature on the involvement of chronic inflammation in the initiation step and in the very early phases of tumorigenesis, in a type of cancer where adult stem cells are assumed to be the cells of origin of neoplasia. Since the gastrointestinal tract is regarded as the best-established model system to address the liaison between chronic inflammation and neoplasia, the focus of this article will be on intestinal cancer. In fact, the anatomy of the intestinal epithelial lining is uniquely suited to study adult stem cells in their niche, and the bowel crypt is an ideal developmental biology system, as proliferation, differentiation and cell migration are all distributed linearly along the long axis of the crypt. Moreover, crypt stem cells are regarded today as the most likely targets of neoplastic transformation in bowel cancer. More specifically, the present review addresses the molecular mechanisms whereby a state of chronic inflammation could trigger the neoplastic process in the intestine, focusing on the generation of inflammatory cues evoking enhanced proliferation in cells not initiated but at risk of neoplastic transformation because of their stemness. Novel experimental approaches, based on triggering an inflammatory stimulus in the neighbourhood of adult intestinal stem cells, are warranted to address some as yet unanswered questions. A possible approach, the targeted transgenesis of Paneth cells, may be aimed at 'hijacking' the crypt stem cell niche from a status characterized by the maintenance of homeostasis to local chronic inflammation, with the prospect of initiating

    The solubility of glycogen, essential to its metabolism, is a property of its shape, a sphere generated through extensive branching during synthesis. Lafora disease (LD) is a severe teenage-onset neurodegenerative epilepsy and results from multiorgan accumulations, termed Lafora bodies (LB), of abnormally structured aggregation-prone and digestion-resistant glycogen. LD is caused by loss-of-function mutations in the EPM2A or EPM2B gene, encoding the interacting laforin phosphatase and malin E3 ubiquitin ligase enzymes, respectively. The substrate and function of malin are unknown; an early counterintuitive observation in cell culture experiments that it targets laforin to proteasomal degradation was not pursued until now. The substrate and function of laforin have recently been elucidated. Laforin dephosphorylates glycogen during synthesis, without which phosphate ions interfere with and distort glycogen construction, leading to LB. We hypothesized that laforin in excess or not removed following its action on glycogen also interferes with glycogen formation. We show in malin-deficient mice that the absence of malin results in massively increased laforin preceding the appearance of LB and that laforin gradually accumulates in glycogen, which corresponds to progressive LB generation. We show that increasing the amounts of laforin in cell culture causes LB formation and that this occurs only with glycogen binding-competent laforin. In summary, malin deficiency causes increased laforin, increased laforin binding to glycogen, and LB formation. Furthermore, increased levels of laforin, when it can bind glycogen, causes LB. We conclude that malin functions to regulate laforin and that malin deficiency at least in part causes LB and LD through increased laforin binding to glycogen. PMID:22669944

    Full Text Available Still’s disease is a disease of unknown etiology that was identified for the first time in 1897 by George Still who noted the association of fever, arthralgias and cutaneous rash in a group of 22 children. In 1971, Bywaters noticed that this symptomatology could also be found in adult patients. High fever, arthralgias, a diffuse cutaneous rash with sore throat, increased spleen volume and lymph nodes are the clinical manifestations of this disease. However, it shows high variability in its clinical presentation (monocyclic, polycyclic and chronic forms. Blood tests show high levels of white blood cells, increased ferritin levels, and negative autoantibodies and rheumatoid factor. We examined 2 clinical cases that strongly suggested adult Still’s disease: a 38- year old woman and a 30-year old man. The woman came to our attention because of the following symptomatology: fever for more than eleven days before hospitalization and polyarthralgias. Blood tests showed high inflammatory markers (ferritin >35,000, low platelets and increased white blood cells. A diffuse rash and oral aphthae were then observed. The second case presented the following symptoms: fever (38.4°C, cutaneous rash, polyarthralgias, and sore throat. Blood tests showed high levels of inflammatory markers and blood cell count showed an increase in neutrophil levels. Abdominal ultrasonography showed hepatosplenomegaly. Concentrating on these elements allowed us to formulate the diagnosis of adult Still’s disease, both patients showing a highly suggestive clinical profile. Yamaguchi’s criteria were satisfied and different diseases could be excluded according to the pharmacological response to anti-inflammatory drugs. This strengthened our diagnostic hypothesis and allowed us to focus our attention on this unknown disease, often unrecognized because of the problems of diagnosis. In fact, the clinical characters are initially aspecific (sore throat and fever. Furthermore

    Moya-Moya disease is a chronic infrequent vasculopathy. Occasionally such abnormalities are found in association with one of many conditions, in these cases the angiographic abnormality should be termed Moya-Moya syndrome rather than Moya-Moya disease. Although in children the usual manifestations are ischemic events and seizures. This clinical presentation is infrequent in adults. We present a 42-years-old man with a 1-month history of recurrent right sided partial somatosensorial seizures, later he presented a left parietal infarction, the angiographic findings were compatible with moyamoya syndrome.

    The objective of this study was to characterize and compare muscle histopathological findings in 3 different genetic motor neuron disorders. We retrospectively re-assessed muscle biopsy findings in 23 patients with autosomal dominant lower motor neuron disease caused by p.G66V mutation in CHCHD10 (SMAJ), 10 X-linked spinal and bulbar muscular atrophy (SBMA) and 11 autosomal dominant c9orf72-mutated amyotrophic lateral sclerosis (c9ALS) patients. Distinct large fiber type grouping consisting of non-atrophic type IIA muscle fibers were 100% specific for the late-onset spinal muscular atrophies (SMAJ and SBMA) and were never observed in c9ALS. Common, but less specific findings included small groups of highly atrophic rounded type IIA fibers in SMAJ/SBMA, whereas in c9ALS, small group atrophies consisting of small-caliber angular fibers involving both fiber types were more characteristic. We also show that in the 2 slowly progressive motor neuron disorders (SMAJ and SBMA) the initial neurogenic features are often confused with considerable secondary "myopathic" changes at later disease stages, such as rimmed vacuoles, myofibrillar aggregates and numerous fibers reactive for fetal myosin heavy chain (dMyHC) antibodies. Based on our findings, muscle biopsy may be valuable in the diagnostic work-up of suspected motor neuron disorders in order to avoid a false ALS diagnosis in patients without clear findings of upper motor neuron lesions.

    Cartilage hair hypoplasia (CHH) is an autosomal recessive disorder caused by mutations in the ribonuclease mitochondrial RNA-processing (RMRP) gene. Although its most constant feature is metaphyseal dysplasia with short stature, CHH is associated with extraskeletal defects such as thin hair, anemia, immunodeficiency, and increased incidence of lymphomas. The spectrum of immunologic phenotypes in CHH translates into clinical severity. Whereas T-cell deficiency may remain subclinical or may result in severe combined immunodeficiency or Omenn syndrome, humoral immunodeficiency has only rarely been noted in these patients. Here we report the diagnosis of CHH in a woman who presented with severe short stature and a full-blown antibody deficiency, clinically resembling common variable immunodeficiency. Sequencing of the RMRP gene revealed compound heterozygosity for two novel mutations (g.68_69delinsTT and g.76C>T). Despite the late onset of immunodeficiency in the patient, its clinical course was severe, and the patient died 3 years after the first diagnosis.

    Calorie restriction (CR) has consistently been shown to increase lifespan and ameliorate disease outcomes. Its effects on behavior are less clear, although anxiolytic-like effects have been observed. Rats were subjected to 1 of 4 dietary regimens: control, CR25%, CR50% and, an acute episode of CR and tested in 3 tests of anxiety: the open field test, the elevated plus maze, and the modified open field test. In the open field test, the CR25% and CR50% groups made more central zone entries than the control and Acute groups, which was primarily due to differences in the initial 5 min of the test. Moreover, both CR groups engaged in greater exploration of the central zone than the control group in the initial 5 min of the test. The Acute group also exhibited significantly longer latencies to leave the central zone at test onset than the control and CR50% group. In the elevated plus maze, the Acute group also displayed longer latencies to open arm entry as compared to the control and CR50% group and showed a lower ratio of open to total arm entries compared to all other groups. There were no effects of CR on any variable of the modified open field test. Possible neurochemical mechanisms underlying the anxiolytic-like effect of CR are discussed.

  1. Metabolic impact of adult-onset, isolated, growth hormone deficiency (AOiGHD due to destruction of pituitary somatotropes.

    Directory of Open Access Journals (Sweden)

    Full Text Available Growth hormone (GH inhibits fat accumulation and promotes protein accretion, therefore the fall in GH observed with weight gain and normal aging may contribute to metabolic dysfunction. To directly test this hypothesis a novel mouse model of adult onset-isolated GH deficiency (AOiGHD was generated by cross breeding rat GH promoter-driven Cre recombinase mice (Cre with inducible diphtheria toxin receptor mice (iDTR and treating adult Cre(+/-,iDTR(+/- offspring with DT to selectively destroy the somatotrope population of the anterior pituitary gland, leading to a reduction in circulating GH and IGF-I levels. DT-treated Cre(-/-,iDTR(+/- mice were used as GH-intact controls. AOiGHD improved whole body insulin sensitivity in both low-fat and high-fat fed mice. Consistent with improved insulin sensitivity, indirect calorimetry revealed AOiGHD mice preferentially utilized carbohydrates for energy metabolism, as compared to GH-intact controls. In high-fat, but not low-fat fed AOiGHD mice, fat mass increased, hepatic lipids decreased and glucose clearance and insulin output were impaired. These results suggest the age-related decline in GH helps to preserve systemic insulin sensitivity, and in the context of moderate caloric intake, prevents the deterioration in metabolic function. However, in the context of excess caloric intake, low GH leads to impaired insulin output, and thereby could contribute to the development of diabetes.

    Niemann-Pick type C disease (NPC) is a recessive neurolipidosis. We report five adolescent and adult NPC cases to underscore the frequency and heterogeneity of movement disorders in NPC. Clinical, morphologic, biochemical and genetic study was performed in the five patients. Disease onset was between 8 and 50 years. Movement disorders were present in all cases, were heterogeneous and often combined [cerebellar ataxia (5/5), myoclonus (3/5), dystonia (2/5), chorea (1/5) and tremor (1/5)] and were the first sign in 4/5. Two patients were reported to have no vertical supranuclear gaze palsy (VSGP) at the first examination. Two patients experienced acute neuropsychiatric signs leading to death in one case due to myoclonic storm. Filipin staining was always positive. Two NPC1 mutations were identified in three patients, only one in two siblings. NPC should be considered in case of unexplained movement disorders, even when VSGP or cataplexy are not reported. Filipin staining remains a strong support for the diagnosis. Treatment with miglustat should be considered which is currently the only approved disease-specific treatment of NPC in children and adults.

    Full Text Available Abstract Background Alexander disease (ALX is a rare neurological disorder characterized by white matter degeneration and cytoplasmic inclusions in astrocytes called Rosenthal fibers, labeled by antibodies against glial fibrillary acidic protein (GFAP. Three subtypes are distinguished according to age at onset: infantile (under age 2, juvenile (age 2 to 12 and adult (over age 12. Following the identification of heterozygous mutations in GFAP that cause this disease, cases of adult-onset ALX have been increasingly reported. Case Presentation We present a 60-year-old Japanese man with an unremarkable past and no family history of ALX. After head trauma in a traffic accident at the age of 46, his character changed, and dementia and dysarthria developed, but he remained independent. Spastic paresis and dysphagia were observed at age 57 and 59, respectively, and worsened progressively. Neurological examination at the age of 60 revealed dementia, pseudobulbar palsy, left-side predominant spastic tetraparesis, axial rigidity, bradykinesia and gaze-evoked nystagmus. Brain MRI showed tadpole-like atrophy of the brainstem, caused by marked atrophy of the medulla oblongata, cervical spinal cord and midbrain tegmentum, with an intact pontine base. Analysis of the GFAP gene revealed a heterozygous missense mutation, c.827G>T, p.R276L, which was already shown to be pathogenic in a case of pathologically proven hereditary adult-onset ALX. Conclusion The typical tadpole-like appearance of the brainstem is strongly suggestive of adult-onset ALX, and should lead to a genetic investigation of the GFAP gene. The unusual feature of this patient is the symmetrical involvement of the basal ganglia, which is rarely observed in the adult form of the disease. More patients must be examined to confirm, clinically and neuroradiologically, extrapyramidal involvement of the basal ganglia in adult-onset ALX.

    Mutations of the huntingtin protein (HTT) gene underlie both adult-onset and juvenile forms of Huntington's disease (HD). HTT modulates mitotic spindle orientation and cell fate in mouse cortical progenitors from the ventricular zone. Using human embryonic stem cells (hESC) characterized as carrying mutations associated with adult-onset disease during pre-implantation genetic diagnosis, we investigated the influence of human HTT and of an adult-onset HD mutation on mitotic spindle orientation in human neural stem cells (NSCs) derived from hESCs. The RNAi-mediated silencing of both HTT alleles in neural stem cells derived from hESCs disrupted spindle orientation and led to the mislocalization of dynein, the p150Glued subunit of dynactin and the large nuclear mitotic apparatus (NuMA) protein. We also investigated the effect of the adult-onset HD mutation on the role of HTT during spindle orientation in NSCs derived from HD-hESCs. By combining SNP-targeting allele-specific silencing and gain-of-function approaches, we showed that a 46-glutamine expansion in human HTT was sufficient for a dominant-negative effect on spindle orientation and changes in the distribution within the spindle pole and the cell cortex of dynein, p150Glued and NuMA in neural cells. Thus, neural derivatives of disease-specific human pluripotent stem cells constitute a relevant biological resource for exploring the impact of adult-onset HD mutations of the HTT gene on the division of neural progenitors, with potential applications in HD drug discovery targeting HTT-dynein-p150Glued complex interactions.

    important due to the possibilities for therapy and family genetic counselling. The main symptoms of IEM in the adult are neurological, followed by hepatic. Two basic modes of onset can be established. One is acute, normally taking the form of consciousness alteration, lethargy, coma of unknown etiology in a previously healthy patient (urea cycle deficits, homocysteine remethylation disorders and porphyries are the most frequent causes. The other is an insidious, often progressive, chronic symptomathology that can involve complex clinical features, and more rarely a symptom that is isolated in a persistent way (Wilson’s disease, mitochondrial diseases, lysosomal storage disorders, Refsum’s disease and glycogenosis are some examples of this group. It is especially important to determine the forms of acute onset as these can present situations of extreme emergency where appropriate conduct can prevent the death of the patient. In this case, simple laboratory examinations, such as determination of ammonia, homocysteine, lactate, acylcarnitines, amino acids, organic and porfirines, can guide the diagnosis and enable the start of intensive treatment. This article provides a practical approach that deals with the general characteristics and the clinical keys for suspecting the most usual IEMs in the adult.

    Adult-onset autosomal dominant leukodystrophy (ADLD) is a rare progressive neurological disorder caused by Lamin B1 duplication (LMNB1). Our aim was to investigate longitudinally the pattern of the autonomic dysfunction and the degree of neuropsychological involvement. Three related ADLD patients and one asymptomatic carrier of LMNB1 duplication underwent a standardized evaluation of autonomic nervous system, including cardiovascular reflexes, pharmacological testing, microneurography, skin biopsy, Metaiodobenzylguanidine scintigraphy and a complete neuropsychological battery. An early neurogenic orthostatic hypotension was detected in all patients and confirmed by a low rise in noradrenaline levels on Tilt Test. However infusion of noradrenaline resulted in normal blood pressure rise as well as the infusion of clonidine. At the insulin tolerance test the increase in adrenaline resulted pathological in two out three patients. Microneurography failed to detect muscle sympathetic nerve activity bursts. Skin biopsy revealed a poor adrenergic innervation, while cardiac sympathetic nerves were normal. None of ADLD patients showed a global cognitive deficit but a selective impairment in the executive functions. Autonomic disorder in ADLD involves selectively the postganglionic sympathetic system including the sympatho-adrenal response. Cognitive involvement consisting in an early impairment of executive tasks that might precede brain MR abnormalities. Copyright © 2016 Elsevier B.V. All rights reserved.

    Late-onset hemorrhagic cystitis (LHC) after hematopoietic stem cell transplantation (HSCT) is mainly caused by viral infections. We retrospectively analyzed the records of 141 Japanese adult patients who underwent a first allogeneic HSCT from 1995 to 2002. In all, 19 patients developed LHC a median of 51 days after HSCT. Adenovirus (AdV) was detected in the urine of 10 LHC patients, of whom eight had AdV type 11. Five of the six available serum samples from these patients were also positive for AdV type 11, but the detection of AdV in serum was not associated with a worse outcome. Male sex and the development of grade II-IV acute graft-versus-host disease were identified as independent significant risk factors for LHC. Male predominance was detected in LHC after HSCT, as has been previously shown in children with AdV-induced acute HC. The detection of AdV DNA in serum did not predict a poor outcome.

    This study tested the hypothesis that adolescent-onset alcohol abuse (AOAA) would both mediate and moderate the effect of childhood conduct disorder on antisocial behaviour in late adolescence and early adulthood. A sample comprising 504 young men and women strategically recruited from the community were grouped using the criteria of the Diagnostic and Statistical Manual (DSM-IV, American Psychiatric Association. (1994). Diagnostic and statistical manual of mental disorders (4th ed.). Washington, DC: APA), as follows: neither childhood conduct disorder (CCD) nor alcohol abuse/dependence; CCD but no alcohol abuse or dependence; alcohol abuse/dependence but no CCD; both CCD and alcohol abuse/dependence. The outcome measure was the sum of positive responses to 55 interview items capturing a variety of antisocial behaviours engaged in since age 15. Severity of lifetime alcohol-related and CCD problems served as predictor variables in regression analysis. Antisocial behaviour problems were greatest in individuals with a history of co-occurring conduct disorder (CD) and alcohol abuse/dependence. While CCD was strongly predictive of adult antisocial behaviour, this effect was both mediated and moderated (exacerbated) by AOAA.

    Full Text Available A 50-year-old female presented with fever, symmetrical arthralgias, rash, painful oral ulcerations and alopecia since 8 weeks. Examination showed mild hepatospleenomegaly. Investigations revealed leucocytosis, neutrophilia, elevated sedimentation rate and raised ferritin levels (3850 ng/ml. Computerized tomography (CT abdomen showed hepatospleenomegaly, mild ascitis and mild bilateral pleural-effusion. After ruling out occult infections, tuberculosis, malignancies and autoimmune diseases by appropriate investigations, and due to raised ferritin levels, adult onset stills disease (AOSD was diagnosed. Patient responded to oral steroids initially, but after 7 days developed severe abdominal pain. Repeat CT showed multiple enlarged, necrotic and matted retroperitoneal lymph nodes with caseating granuloma on histopathology suggesting tuberculosis. Patient was given four-drug anti-tubercular treatment and she improved. Thus our patient of occult abdominal tuberculosis with reactive arthritis (Poncet′s disease presented with hyperferritinemia mimicking AOSD. We postulate that extreme hyperferritinemia can be seen in tuberculosis and tuberculosis must be conclusively ruled out before diagnosing AOSD in tropics.

    Adult-onset Still's disease (AOSD) remains a perplexing, difficult to diagnose clinical entity, with clinical characteristics that are often broad and encountered in numerous other clinical entities. This vague clinical presentation is depicted in the commonly used diagnostic criteria, as the ones by Yamaguchi and Fautrel. The authors sought to investigate how diagnostic criteria apply in a series of 22 new cases of AOSD patients presenting with fever of unknown origin (FUO) and diagnosed at the Internal Medicine Department of Hatzikosta General Hospital of Ioannina, Greece. The aims of the study were: (1) to study the incidence of AOSD and (2) to retrospectively apply different classifications to the data of these patients in search of a more efficient way of diagnosing these patients in the future. The annual incidence of AOSD was estimated at two new cases per 10(5). The clinical manifestations of the patients are discussed, with an emphasis on specific manifestations being considered as criteria by Yamaguchi and Fautrel classifications. Four patients exhibited markedly increased serum D: -dimers, a finding of which the potential pathophysiologic implications are discussed. Serum ferritin levels have additive values, both for diagnostic and cost-reduction purposes in cases presenting as FUO; serum ferritin values are not included in any diagnostic set of criteria at present. The finding of high levels of D-dimers in AOSD needs further studies.

    Adult-onset Still's disease (AOSD), as a category of connective tissue diseases, has about 5∼9% of fever of unknown origin (FUO) cases. Diagnosis of AOSD was challenging because of its nonspecific characteristics. The present study analyzed clinical manifestations and laboratory findings in a series of patients with AOSD from eastern China. Medical records of 61 patients admitted with FUO and with a discharge diagnosis of AOSD were retrospectively evaluated and analyzed with special focus on clinical manifestations and laboratory findings. Compared with previous reports, most features of our patients had a similar incidence rate. Rash (79%), arthralgia (80%), and sore throat (84%) were the most frequent clinical manifestations in our series. Leukocytosis (80%), elevated ESR (98%) and CRP (100%), negative ANA (90%) and RF (93%), and high ferritin level (94%) were the most sensitive laboratory findings in our patients. AOSD was not a rare reason of FUO in eastern China. Fever, arthralgia, rash, sore throat, leukocytosis, neutrophilia, elevated ESR and CRP, negative ANA and RF, and high ferritin level were the most common clinical features in our series. The lack of highly specific characteristic makes the diagnosis of AOSD difficult compared with other diseases in FUO.

    Full Text Available Case. A 34-year-old African-American female with a history of adult-onset Still’s disease presented to an outside hospital with oligoarthritis. She experienced a generalized tonic-clonic seizure en route via ambulance, was intubated upon arrival, and transferred to the intensive care unit for treatment of suspected pneumonia and sepsis. She subsequently developed generalized cutaneous desquamation that progressed despite the cessation of antibiotics and other potential offending drugs which required transfer to our hospital’s burn unit. She was suspected to have reactive hemophagocytic syndrome based on her clinical presentation of fever, rash, polyarthritis, elevated liver enzymes, coagulopathy, splenomegaly, normocytic anemia, thrombocytopenia, hypertriglyceridemia, hyperferritinemia, and hemophagocytosis visualized in bone marrow biopsy specimen. Magnetic resonance imaging demonstrated necrotic demyelination of the deep white matter and corona radiata. The patient developed multiorgan dysfunction and DIC without any other attributable etiology. Despite aggressive broad spectrum therapy and high dose of steroids she progressively deteriorated and eventually expired. Conclusion. Previous publications have highlighted the prevalence of necrotic leukoencephalopathy in children with familial hemophagocytic syndrome. Our patient demonstrated some uncommon features complicating her HLH including DIC and necrotic leukoencephalopathy, which are very rare entities in AOSD.

    To assess the risks for adult-onset acute leukemia associated with employment in the New Zealand meat industry. A total of 110 incident leukemia cases identified from referrals to one of six treatment centers between 1989 and 1991 were compared with 199 general population controls. Detailed occupational exposure histories were obtained by interview. There was an elevated risk associated with ever having worked in an abattoir (OR = 2.3, 95% CI 1.0-5.2), which appeared confined to those with over 2 years exposure (OR = 4.9, 95% CI 1.5-15.6). The excess risk was confined to abattoir workers having direct contact with animals or animal products (OR = 5.2 95% CI 1.2-22.2). Ever having worked as a butcher was associated with elevated risk (OR = 2.9, 95% CI 1.1-7.2), confined to those individuals who worked as a butcher in an abattoir (OR = 4.8) or who butchered livestock on farms (OR = 8.2). No increased risk was found for work as a retail/wholesale butcher or meatpacker (OR = 1.2). This study found increased leukemia risks associated with employment in the meat industry. These were confined to abattoir workers with over 2 years employment in the industry, and to persons whose jobs involved contact with animals or animal tissue, implying that biological exposures may be responsible.

    Phospholipase D2 (PLD2) is an enzyme that produces phosphatidic acid (PA), a lipid messenger molecule involved in a number of cellular events including, through its membrane curvature properties, endocytosis. The PLD2 knock out (PLD2KO) mouse has been previously reported to be protected from insult in a model of Alzheimer's disease. We have further analysed a PLD2KO mouse using mass spectrophotometry of its lipids and found significant differences in PA species throughout its brain. We have examined the expression pattern of PLD2 which allowed us to define which region of the brain to analyse for defect, notably PLD2 was not detected in glial-rich regions. The expression pattern lead us to specifically examine the mitral cells of olfactory bulbs, the Cornus Amonis (CA) regions of the hippocampus and the Purkinje cells of the cerebellum. We find that the change to longer PA species correlates with subtle architectural defect in the cerebellum, exemplified by ectopic Purkinje cells and an adult-onset deficit of olfaction. These observations draw parallels to defects in the reelin heterozygote as well as the effect of high fat diet on olfaction. PMID:27658289

    We present a two-generation family consisting of a father and two daughters, who had an adult-onset leukodystrophy characterized by widespread destruction of cerebral white matter with neuroaxonal spheroids. The mode of inheritance appears to be autosomal dominant. All three patients presented with a variety of motor and cognitive symptoms, including frontal lobe signs, 4-7 years before death. Each followed a chronic course until death at ages 39, 46, and 51. At autopsy, the white matter loss was widespread but most prominent in the cerebrum with descending corticospinal tract degeneration and relative sparing of subcortical U-fibers. Pigmented glial cells were present, most of which appear to be macrophages, but inconstantly Prussian blue-positive. This disease is consistent with published reports of hereditary diffuse leukoencephalopathy with spheroids (HDLS). However, a review of the literature and a personal review of the neuropathology of the original case of the pigmentary type of orthochromatic leukodystrophy (POLD) reveal overlapping clinical and neuropathologic features between these two previously distinct entities, suggesting a common pathogenetic and perhaps etiological relationship between the two.

    We describe detailed clinical, biochemical, neuroimaging and neuropathological features in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), encompassing hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) and pigmentary orthochromatic leukodystrophy (POLD), linked to colony-stimulating factor 1 receptor (CSF1R) mutations in four Korean cases. Clinical, biochemical, neuroimaging and neuropathological findings were obtained by direct evaluation and from previous medical records. The genetic analysis of the CSF1R gene was done in two autopsy-confirmed ALSP cases and two cases where ALSP was suspected based on the clinical and neuroimaging characteristics. We identified two known mutations: c.2342C>T (p.A781V) in one autopsy-proven HDLS and clinically ALSP-suspected case and c.2345G>A (p.R782H) in another autopsy-proven POLD case. We also found a novel mutation (c.2296A>G; p.M766V) in a patient presenting with hand tremor, stuttering and hesitant speech, and abnormal behavior whose father died from a possible diagnosis of spinocerebellar ataxia. To the best of our knowledge, this is the first documented ALSP-linked CSF1R mutation in Korea and supports the suggestion that HDLS and POLD, with pathological characteristics that are somewhat different but which are caused by CSF1R mutations, are the same spectrum of disease, ALSP.

    It has been reported that glycogen levels in retina vary with retinal vascularization. However, the electrical activity of isolated retina depends on glucose supply, suggesting that it does not contain energetic reserves. We determined glycogen levels and pyruvate and lactate production under various conditions in isolated retina. Ex vivo retinas from light- and dark-adapted rats showed values of 44 +/- 0.3 and 19.5 +/- 0.4 nmol glucosyl residues/mg protein, respectively. The glycogen content of retinas from light-adapted animals was reduced by 50% when they were transferred to darkness. Glycogen levels were low in retinas incubated in glucose-free media and increased in the presence of glucose. The highest glycogen values were found in media containing 20 mm of glucose. A rapid increase in lactate production was observed in the presence of glucose. Surprisingly, glycogen levels were the lowest and lactate production was also very low in the presence of 30 mm glucose. Our results suggest that glycogen can be used as an immediate accessible energy reserve in retina. We speculate on the possibility that gluconeogenesis may play a protective role by removal of lactic acid.

    Full Text Available BACKGROUND: Obesity invokes a range of metabolic disturbances, but the transition from a poor to excessive nutritional environment may exacerbate adult metabolic dysfunction. The current study investigated global maternal nutrient restriction during early or late gestation on glucose tolerance and insulin sensitivity in the adult offspring when lean and obese. METHODS/PRINCIPAL FINDINGS: Pregnant sheep received adequate (1.0M; CE, n = 6 or energy restricted (0.7M diet during early (1-65 days; LEE, n = 6 or late (65-128 days; LEL, n = 7 gestation (term approximately 147 days. Subsequent offspring remained on pasture until 1.5 years when all received glucose and insulin tolerance tests (GTT & ITT and body composition determination by dual energy x-ray absorptiometry (DXA. All animals were then exposed to an obesogenic environment for 6-7 months and all protocols repeated. Prenatal dietary treatment had no effect on birth weight or on metabolic endpoints when animals were 'lean' (1.5 years. Obesity revealed generalised metabolic 'inflexibility' and insulin resistance; characterised by blunted excursions of plasma NEFA and increased insulin(AUC (from 133 to 341 [s.e.d. 26] ng.ml(-1.120 mins during a GTT, respectively. For LEL vs. CE, the peak in plasma insulin when obese was greater (7.8 vs. 4.7 [s.e.d. 1.1] ng.ml(-1 and was exacerbated by offspring sex (i.e. 9.8 vs. 4.4 [s.e.d. 1.16] ng.ml(-1; LEL male vs. CE male, respectively. Acquisition of obesity also significantly influenced the plasma lipid and protein profile to suggest, overall, greater net lipogenesis and reduced protein metabolism. CONCLUSIONS: This study indicates generalised metabolic dysfunction with adult-onset obesity which also exacerbates and 'reveals' programming of glucose-insulin sensitivity in male offspring prenatally exposed to maternal undernutrition during late gestation. Taken together, the data suggest that metabolic function appears little compromised in young

  5. Lumbar spine spondylolysis in the adult population: using computed tomography to evaluate the possibility of adult onset lumbar spondylosis as a cause of back pain

    To determine if new onset of low back pain in adults could be secondary to lumbar spondylolysis by establishing the age-related prevalence in the general population by examining patients undergoing computed tomography (CT) for reasons unrelated to back pain. The records of 2,555 patients who had undergone abdominal and pelvic CT in 2008 were reviewed electronically. In order to determine a true representation of the general population, we reviewed all indications for CT, excluding patients with a primary complaint of low back pain as the primary indication for imaging. Equal numbers of patients were separated into age groups by decade to ensure an even distribution of ages for statistical analysis. Patients older than 70 years were grouped together to provide case numbers comparable to those of the other decades. Logistic regression analysis was performed to evaluate the significance of the results. Three board-certified radiologists, including two musculoskeletal fellows and a radiology resident, retrospectively evaluated CT scans for lumbar spondylolysis, including unilateral and bilateral defects. Of the 2,555 cases evaluated, there were 203 positive cases of defects of the lumbar pars interarticularis. This corresponded to an overall prevalence of 8.0%. Prevalence per decade was fairly evenly distributed and ranged from 7.0%(ages 30-39 years) to 9.2% (ages 70 years and above). Prevalence of ages 20-49 years was 7.9%, and that of ages 50 years and older was 8.0%. Male to female ratio was 1.5:1. Logistic regression showed no significant increase in spondylolysis based on age. No significant increase in the prevalence of lumbar spondylolysis was demonstrated in patients older than 20 years. This suggests that the development of symptomatic lumbar pars defects do not occur in this population and should not be considered as a rare but potentially treatable cause of new onset low back pain in adults. This study demonstrated an overall prevalence of pars defects of 8

    Rheumatic diseases of childhood, in particular juvenile idiopathic arthritis, are chronic conditions associated with considerable morbidity and mortality that can have repercussions on aspects of adult life. The aim of this study was to determine the employment rate and social status of patients with childhood-onset rheumatic disease attending a pediatric rheumatology transition unit. A census was taken of patients seen in the Pediatric Rheumatology Transition Unit of Hospital Vall d'Hebron (Barcelona, Spain). We collected demographic and clinical variables and determined the patients' functional capacity. All patients seen during the period of September to December 2013 underwent a survey containing items related to their social situation, maximum academic level achieved, and working life. Correlations were sought between clinical variables associated with a poor prognosis and the patients' job performance. The data were analyzed and compared with those of an age-matched cohort from the general population of Catalonia. Of 130 patients included in the census, 96 responded to the survey. Steinbrocker grade III and IV disability (poorer functional capacity) (p = 0.0025) and longer disease duration (p = 0.017) were significantly related to greater difficulty getting a job. Patients with grade III and IV disability and those with more severe disease showed trends to having more problems carrying out work-related tasks. Our cohort included a higher percentage of students than the age-matched comparison population (50 % vs 24 %, respectively) (p = 0.0001); 82 % of patients had completed studies beyond the compulsory education level. The employment rate was lower in our patient cohort than in the comparison cohort (38.3 % vs 59.9 %) (p = 0.0001), whereas the percentage of unemployed was similar. Patients with milder disease had a higher probability of living with their parents up to a later age (OR = 3.2, 95 % CI 0.38-6.15; p = 0

    We have established a new method for the enzymatic diagnosis of glycogen storage disease type II (Pompe disease or acid maltase deficiency) using mixed leukocytes. The method employs glycogen and 4-methylumbelliferyl-alpha-D-glucopyranoside (4MU-alphaGlc) as substrates for measuring the lysosomal acid alpha-glucosidase (acid alphaGlu) activity, and incorporates acarbose to eliminate the interference of unrelated alpha-glucosidases (predominantly maltase-glucoamylase). It is shown that 3.0 micromol/L acarbose completely inhibits the maltase-glucoamylase activity at pH 4.0, but the lysosomal acid alphaGlu activity by less than 5%. With this method, we determined the acid alphaGlu activity in mixed leukocytes from 25 patients with glycogen storage disease type II (2 infantile and 23 late-onset cases), one GAA2/GAA2 homozygote and 30 healthy subjects. In the assay with glycogen as substrate, the addition of acarbose created a clear separation between the patient and the control ranges. In the assay with 4MU-alphaGlc as substrate, the two ranges were fully separated but remained very close despite the use of acarbose. The separation of the patient and normal ranges was improved considerably by taking the ratio of acarbose-inhibited over uninhibited activity. A GAA2/GAA2 homozygote was correctly diagnosed with 4MU-alphaGlc but misdiagnosed as patient when glycogen was used as substrate. We conclude that the inclusion of 3.0 micromol/L acarbose in the assays with glycogen and 4MU-alphaGlc substrates at pH 4.0 allows for the specific measurement of lysosomal acid alphaGlu activity in mixed leukocytes, thus enabling a reliable diagnosis of glycogen storage disease type II in this specimen.

    Growth hormone (GH) and insulin-like growth factor-I (IGF-I) provide trophic support during development and also appear to influence cell structure, function and replacement in the adult brain. Recent studies demonstrated effects of the GH/IGF-I axis on adult neurogenesis, but it is unclear whether the GH/IGF-I axis influences glial turnover in the normal adult brain. In the current study, we used a selective model of adult-onset GH and IGF-I deficiency to evaluate the role of GH and IGF-I in regulating glial proliferation and survival in the adult corpus callosum. GH/IGF-I-deficient dwarf rats of the Lewis strain were made GH/IGF-I replete via twice daily injections of GH starting at postnatal day 28 (P28), approximately the age at which GH pulse amplitude increases in developing rodents. GH/IGF-I deficiency was initiated in adulthood by removing animals from GH treatment. Quantitative analyses revealed that adult-onset GH/IGF-I deficiency decreased cell proliferation in the white matter and decreased the survival of newborn oligodendrocytes. These findings are consistent with the hypothesis that aging-related changes in the GH/IGF-I axis produce deficits in ongoing turnover of oligodendrocytes, which may contribute to aging-related cognitive changes and deficits in remyelination after injury.

    A case of hereditary fructose intolerance is reported in a girl aged 2 years at the time of her death. She had apparently progressed normally until the age of 14 months. At 19 months she was admitted to hospital with failure to thrive, hepatomegaly, and superficial infections. Investigations revealed hypoglycaemia, persistent acidosis, aminoaciduria, and a high liver glycogen level which suggested that she had glycogen storage disease. There was also some evidence of malabsorption. At necropsy the liver enzyme estimations showed that fructose 1-phosphate aldolase activity was absent and that fructose 1,6-diphosphate aldolase activity was reduced. Hereditary fructose intolerance and glycogen storage disease have been confused in the past on clinical grounds, but a high liver glycogen level has not previously been reported in hereditary fructose intolerance.

    6 of 10 PTC cases with ALK rearrangements versus 2 of 15 cases with no ALK rearrangements. The six radiation-exposed cases of PTC harboring both ALK rearrangements and solid/trabecular-like architecture were associated with higher radiation doses and younger ages at the time of the A-bombing and at diagnosis compared to the other 19 PTC with no detectable gene alterations. Our findings suggest that ALK rearrangements are involved in the development of radiation-induced adult-onset PTC.

    Full Text Available To search for biomarkers to differentiate primary focal segmental glomerulosclerosis (FSGS and minimal change disease (MCD.We isolated glomeruli from kidney biopsies of 6 patients with adult-onset steroid sensitiveFSGS and 5 patients with MCD, and compared the profiles of glomerular transcriptomes between the two groups of patients using microarray analysis.Analysis of differential expressed genes (DEGs revealed that up-regulated DEGs in FSGS patients compared with MCD patients were primarily involved in spermatogenesis, gamete generation, regulation of muscle contraction, response to unfolded protein, cell proliferation and skeletal system development. The down-regulated DEGs were primarily related to metabolic process, intracellular transport, oxidation/reduction andestablishment of intracellular localization. We validated the expression of the top 6 up-regulated and top 6 down-regulated DEGs using real-time PCR. Membrane metallo-endopeptidase (MME is a down-regulated gene that was previously identified as a key gene for kidney development. Immunostaining confirmed that the protein expression of MME decreased significantly in FSGS kidneys compared with MCD kidneys.This report was the first study to examine transcriptomes in Chinese patients with various glomerular diseases. Expressions of MME both in RNA and protein level decreased significantly in glomeruli of FSGS kidneys compared with MCD kidneys. Our data suggested that MME might play a role in the normal physiological function of podocytes and a decrease in MME expression might be related to podocyte injury. We also identified genes and pathways specific for FSGS versus MCD, and our data could help identify potential new biomarkers for the differential diagnosis between these two diseases.

    Adult-onset type II citrullinemia (CTLN2), an autosomal recessive disorder caused by a mutation in the SLC25A13 gene, is characterized by increased serum citrulline and ammonia levels. Patients with CTLN2 also display various neuropsychiatric symptoms. Many individuals with CTLN2 are fond of protein-rich and/or lipid-rich foods with an aversion to carbohydrate-rich foods. We herein report two cases of CTLN2 treated with living donor liver transplantation (LDLT) and provide a review of the pertinent literature. Case 1 was a 43-year-old man admitted to our hospital for repetitive episodes of consciousness disturbance. Case 2 was a 37-year-old man admitted to our hospital because of abnormal behavior associated with hyperammonemia. A definitive diagnosis of CTLN2 was accomplished by DNA analysis in both patients, who successfully underwent LDLT using liver segments from donor siblings with confirmed heterozygous gene expression. Case 2 also underwent conservative therapy with arginine and a high-fat, carbohydrate-restricted diet prior to LDLT. Postoperative recovery was uneventful and food was unrestricted in both patients. We also identified 77 cases of CTLN2 in the literature and reviewed them in terms of outcome of both liver transplantation and conservative therapy. The survival rate in patients treated by liver transplantation was 100%, whereas that in patients treated by conservative treatment showed improvement from 39.5% to 76.5% over the years. Liver transplantation is a practical treatment that fundamentally improves patient quality of life after transplantation. However, recent studies have suggested that arginine and sodium pyruvate administration combined with intensive nutritional support is also an effective therapy for CTLN2. Further development of conservative therapy may provide a safer, more affordable alternative to liver transplantation in the near future.

    Background: Chronic stress resulting from experiences of racism may increase the incidence of adult-onset asthma through effects on the immune system and the airways. We conducted prospective analyses of the relation of experiences of racism with asthma incidence in the Black Women’s Health Study, a prospective cohort of black women in the United States followed since 1995 with mailed biennial questionnaires. Methods: Among 38,142 participants followed from 1997 to 2011, 1,068 reported incident asthma. An everyday racism score was created based on five questions asked in 1997 and 2009 about the frequency in daily life of experiences of racism (eg, poor service in stores), and a lifetime racism score was based on questions about racism on the job, in housing, and by police. We used Cox regression models to derive multivariable incidence rate ratios (IRRs) and 95% CIs for categories of each racism score in relation to incident asthma. Results: The IRRs were 1.45 (95% CI, 1.19-1.78) for the highest compared with the lowest quartile of the 1997 everyday racism score (P for trend racism. Among women who reported the same levels of racism in 1997 and 2009, the IRRs for the highest categories of everyday and lifetime racism were 2.12 (95% CI, 1.55-2.91) and 1.66 (95% CI, 1.20-2.30), respectively. Conclusions: Given the high prevalence of experiences of racism and asthma in black women in the United States, a positive association between racism and asthma is of public health importance.

  18. The Effects of Proprioceptive Neuromuscular Facilitation Stretching on Post-Exercise Delayed Onset Muscle Soreness in Young Adults.

    McGRATH, Ryan P; Whitehead, James R; Caine, Dennis J

    Until recently, the scientific community believed that post-exercise stretching could reduce delayed onset muscle soreness (DOMS), but recent reviews of studies on the topic have concluded that pre- or post-exercise static stretching has no effect on mitigating DOMS. However, the effect of proprioceptive neuromuscular facilitation (PNF) post-exercise stretching on preventing DOMS has not been adequately studied. The purpose of this study was to determine the effect of post-exercise PNF stretching on DOMS. Young adult participants (N=57) were randomly assigned to a PNF stretching group (n=19), a static stretching group (n=20), and to a no-stretching control group (n=18). All participants completed exercise designed to induce DOMS prior to post-exercise experimental stretching protocols. Participants rated their soreness level on a pain scale 24 and 48 hours post-exercise. A 3 × 2 mixed ANOVA showed there was an effect for time (p<.01). Post hoc testing revealed that DOMS pain significantly decreased (p<.05) from 24 to 48 hours post-exercise for the PNF and control groups, but not for the static stretching group. Other analyses revealed a significant correlation (r=.61, p<.01) between the pre- and post-exercise stretch scores and the 48 hour post-exercise pain score for the PNF group. Consistent with the results of previous research on post-exercise static stretching, these results indicate that post-exercise PNF stretching also does not prevent DOMS. However, the correlation analysis suggests it is possible the pre-stretch muscle contractions of the post-exercise PNF protocol may have placed a load on an already damaged muscle causing more DOMS for some participants.

    To establish and validate diagnostic criteria for adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) due to colony stimulating factor 1 receptor (CSF1R) mutation. We developed diagnostic criteria for ALSP based on a recent analysis of the clinical characteristics of ALSP. These criteria provide "probable" and "possible" designations for patients who do not have a genetic diagnosis. To verify its sensitivity and specificity, we retrospectively applied our criteria to 83 ALSP cases who had CSF1R mutations (24 of these were analyzed at our institutions, and the others were identified from the literature), 53 cases who had CSF1R mutation-negative leukoencephalopathies, and 32 cases who had cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) with NOTCH3 mutations. Among the CSF1R mutation-positive cases, 50 cases (60%) were diagnosed as "probable" and 32 (39%) were diagnosed as "possible," leading to a sensitivity of 99% if calculated as a ratio of the combined number of cases who fulfilled "probable" or "possible" to the total number of cases. With regard to specificity, 22 cases (42%) with mutation-negative leukoencephalopathies and 28 (88%) with CADASIL were correctly excluded using these criteria. These diagnostic criteria are very sensitive for diagnosing ALSP with sufficient specificity for differentiating from CADASIL and moderate specificity for other leukoencephalopathies. Our results suggest that these criteria are useful for the clinical diagnosis of ALSP. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    Adult-onset Still's disease is a systemic inflammatory disease which presents with uveitis and scleritis in the eye. Intravitreal dexamethasone implants are used for the treatment of refractory uveitis. A 19-year-old woman diagnosed to have adult-onset Still's disease for fevers, joint pain, and a salmon-colored bumpy rash presented with scleritis and uveitis in the left eye. Topical and systemic steroids with oral methotrexate failed to control the inflammation. We performed intravitreal injections of dexamethasone implants for side effects of steroid and refractory ocular inflammation. The therapy resulted in improvements in the patient's uveitis with reductions in scleral vessel engorgement and redness. There was no recurrence of uveitis or scleritis during 4 months following treatment. Intravitreal injections of dexamethasone implants may result in clinical improvements of refractory scleritis combined with uveitis.

    Delayed sleep phase disorder is characterized by a delay in the timing of the major sleep period relative to conventional norms. The sleep period itself has traditionally been described as normal. Nevertheless, it is possible that sleep regulatory mechanism disturbances associated with the disorder may affect sleep duration and/or architecture. Polysomnographic data that may shed light on the issue are scarce. Hence, the aim of this study was to examine polysomnographic measures of sleep in adolescents and young adults with delayed sleep phase disorder, and to compare findings to that of healthy controls. A second aim was to estimate dim light melatonin onset as a marker of circadian rhythm and to investigate the phase angle relationship (time interval) between dim light melatonin onset and the sleep period. Data from 54 adolescents and young adults were analysed, 35 diagnosed with delayed sleep phase disorder and 19 healthy controls. Results show delayed timing of sleep in participants with delayed sleep phase disorder, but once sleep was initiated no group differences in sleep parameters were observed. Dim light melatonin onset was delayed in participants with delayed sleep phase disorder, but no difference in phase angle was observed between the groups. In conclusion, both sleep and dim light melatonin onset were delayed in participants with delayed sleep phase disorder. The sleep period appeared to occur at the same circadian phase in both groups, and once sleep was initiated no differences in sleep parameters were observed.

    Factors that influence smoking initiation and age of smoking onset are important considerations in tobacco control. We evaluated European Union (EU)-wide differences in the age of onset of regular smoking, and the potential role of peer, parental and tobacco product design features on the earlier onset of regular smoking among adults current and former smokers aged 15-39 years, collected for the Eurobarometer 77.1 survey (2012). Respondents reported their age at regular smoking onset and factors that influenced their decision to start smoking, including peer influence, parental influence and features of tobacco products. Multi-variable logistic regression, adjusted for age; geographic region; education; difficulty to pay bills; and gender, was used to assess the role of the various pro-tobacco influences on early onset of regular smoking (i.e. parents (OR = 1.60; 95%CI 1.21-2.12) were more likely to have started smoking regularly patterns among EU countries, which may warrant different approaches in the prevention of tobacco use. © The Author 2015.

    The thermoacidophilic red microalga Galdieria sulphuraria synthesizes glycogen when growing under heterotrophic conditions. Structural characterization revealed that G. sulphuraria glycogen is the most highly branched glycogen described to date, with 18% of α-(1→6) linkages. Moreover, it differs from other glycogens because it is composed of short chains only and has a substantially smaller molecular weight and particle size. The physiological role of this highly branched glycogen in G. sulphuraria is discussed.

    Severe knee flexion contractures greater than 80° are rare and challenging to manage. Previous studies have demonstrated unsatisfactory clinical results after correcting these deformities because residual flexion contractures were not corrected within a short period of time. We herein report the case of a patient with adult-onset Still's disease with 90° of bilateral knee flexion contracture, which was successfully corrected by total knee arthroplasty and serial casting over a period of five weeks. A 47-year-old male was admitted to our orthopedic department for bilateral knee pain and a preoperative fixed flexion contracture of 90°. A diagnosis of adult-onset Still's disease was made based on the patient's medical history of a high spiking fever, salmon-colored rash and bilateral knee and wrist pain. Bilateral total knee arthroplasty was carried out to address these deformities, but residual flexion contracture was present. Subsequently, serial casting was used to achieve full extension at four weeks after surgery. Excellent function and patient satisfaction were observed at two years of follow-up. The new protocol of total knee arthroplasty with subsequent serial casting seems to be an efficient solution for knee flexion contractures greater than 80°. This report adds to the very small number of reported cases of adult-onset Still's disease with severe knee flexion contractures and describes a patient who was successfully treated with a new protocol.

    Although birth weight is considered as a fetal determinant of the development of adult-onset diabetes mellitus (DM), its public health importance relative to adult body mass index (BMI) remains unclear. We aimed to examine the association between adult-onset DM and birth weight in relation to adult BMI. We conducted a self-administered questionnaire as a baseline survey of the Japanese Nurses' Health Study cohort between 2001 and 2007. Exclusion criteria were applied to the volunteer sample of 49,927 female nurses (age <30 years or unknown, current pregnancy, development of DM before the age of 30 years, unknown core variables), and data from 26,949 female nurses aged 30 years or older were used. The association between history of DM diagnosis and birth weight was analyzed using logistic regression. A linear inverse association was observed between birth weight and DM, after adjustment for age, BMI, and parental history of DM. The odds ratio for developing DM per 100 g increase in birth weight was 0.93 (95% confidence interval [CI], 0.90-0.96). The association was unchanged when birth weight was converted to percentile for gestational age. In the BMI-stratified analysis, the odds ratio for DM in the <2500 g birth weight group reached 4.75 (95% CI, 1.22-18.44, compared to the reference 3000-3499 g group) among women with normal low BMI (18.5-20.9). Birth weight and its percentile for gestational age were associated with adult-onset DM. Attention should be paid to the risk of DM among women born with low weight, even when their current BMI is normal. Copyright © 2017 The Authors. Production and hosting by Elsevier B.V.

  10. Regulation of glycogen resynthesis following exercise. Dietary considerations.

    1991-04-01

    With the cessation of exercise, glycogen repletion begins to take place rapidly in skeletal muscle and can result in glycogen levels higher than those present before exercise. Understanding the rate-limiting steps that regulate glycogen synthesis will provide us with strategies to increase the resynthesis of glycogen during recovery from exercise, and thus improve performance. Given the importance of muscle glycogen to endurance performance, various factors which may optimise glycogen resynthesis rate and insure complete restoration have been of interest to both the scientist and athlete. The time required for complete muscle glycogen resynthesis after prolonged moderate intensity exercise is generally considered to be 24 hours provided approximately 500 to 700g of carbohydrate is ingested. Muscle glycogen synthesis rate is highest during the first 2 hours after exercise. Ingestion of 0.70g glucose/kg bodyweight every 2 hours appears to maximise glycogen resynthesis rate at approximately 5 to 6 mumol/g wet weight/h during the first 4 to 6 hours after exhaustive exercise. Further enhancement of glycogen resynthesis rate with ingestion of greater than 0.70g glucose/kg bodyweight appears to be limited by the constraints imposed by gastric emptying. Ingestion of glucose or sucrose results in similar muscle glycogen resynthesis rates while glycogen synthesis in liver is better served with the ingestion of fructose. Also, increases in muscle glycogen content during the first 4 to 6 hours after exercise are greater with ingestion of simple as compared with complex carbohydrate. Glycogen synthase activity is a key component in the regulation of glycogen resynthesis. Glycogen synthase enzyme exists in 2 states: the less active, more phosphorylated (D) form which is under allosteric control of glucose-6-phosphate, and the more active, less phosphorylated (I) form which is independent of glucose-6-phosphate. There is generally an inverse relationship between glycogen content

    To observe the efficacy and safety of leflunomide combined with prednisone therapy (LEF therapy) in the treatment of patients with adult onset steroid-dependent and steroid-resistant minimal change disease (MCD). 16 MCD patients who had been treated with LEF therapy were retrospectively analyzed. 87.5% (14/16) of the patients were steroid-dependent and 12.5% (2/16) of the patients were steroid-resistant. The initial dose of LEF was 10 - 20 mg/day combined with prednisone 0.25 - 1.0 mg/kg/day, gradually tapering after 8 weeks. Clinical and laboratory data at baseline, 2nd, 4th, 8th, 12th, 24th, and 48th week were analyzed compared with initial course of prednisone monotherapy (PRED monotherapy) and cyclophosphamide combined with prednisone therapy (CTX therapy). All the 16 patients achieved different levels of remission in LEF therapy. 93.8% (15/16) of the patients, including the two steroid-resistant patients, achieved complete remission. During the treatment, 8 patients had adverse effects which could be well tolerated. Compared LEF therapy with PRED monotherapy (n = 16), the dose of prednisone to maintain remission was reduced (from median 22.5 mg/day to median 7.5 mg/day, p = 0.041); relapse rate during the follow-up decreased from 100% to 31.3% (p = 0.002); the median time before relapse increased from 20.3 weeks to 32.5 weeks. Compared LEF therapy with CTX therapy (n = 12), the dose of prednisone to maintain remission was reduced significantly (from median 22.5 mg/day to median 5.0 mg/day, p = 0.003); relapse rate during the follow-up decreased from 100% to 31.3% (p = 0.001); the median time before relapse increased from 11.7 weeks to 32.5 weeks. LEF therapy seems to be effective in steroid-resistant and steroiddependent MCD. This therapy may reduce the amount of prednisone to maintain remission and reduce the relapse rate compared with PRED monothrerapy and CTX therapy. LEF therapy was usually well tolerated.

    This study explores the pace of severe disability onset with an emphasis on the role of race/ethnicity and education. More specifically, this research examines whether race/ethnicity and educational attainment are independent predictors of progressive and accelerated disability onset. Using the Health and Retirement Study (HRS) Waves 2 to 10 (1994-2010), a series of discrete-time Cox proportional hazards models with multiple competing events were created to ascertain whether respondents developed progressive or accelerated disability in subsequent waves. Black and Hispanic respondents were at an increased risk of developing progressive disability. Respondents without a high school degree were more likely to experience progressive or accelerated disability. Low educational attainment was a particularly strong predictor of accelerated disability onset and may represent an acute lack of resources over the life course. Race and ethnicity were important predictors of progressive disability onset, which may reflect racial/ethnic variations in the disabling process.

    The effects of adult-onset hypothyroidism on the metabolic compartmentation of the cerebral tricarboxylic acid cycle and the gamma-aminobutyric acid (GABA) shunt have been investigated by 13C nuclear magnetic resonance spectroscopy. Rats thyroidectomized as adults and age-matched controls were infused in the right jugular vein with unlabeled or (1,2-13C2) acetate solutions for 60 min. At the end of the infusion, the brains were frozen in situ and perchloric acid extracts were prepared and analyzed by 13C nuclear magnetic resonance and reverse-phase HPLC. Thyroidectomized animals showed a decrease in the incorporation of 13C from (1,2-13C2) acetate in cerebral metabolites and an increase in the concentrations of unlabeled glutamate and GABA. Computer-assisted interpretation of the 13C multiplets observed for the carbons of glutamate, glutamine, and GABA indicated that adult-onset hypothyroidism produced 1) a decrease in the contribution of infused (1,2-13C2) acetate to the glial tricarboxylic acid cycle; 2) an increase in the contribution of unlabeled acetyl-CoA to the neuronal tricarboxylic acid cycle; and 3) impairments in the exchange of glutamate, glutamine, and GABA between the neuronal and glial compartments. Despite the fact that the adult brain has often been considered metabolically unresponsive to thyroid hormone status, present results show metabolic alterations in the neuronal and glial compartments that are reversible with substitution therapy.

    Few studies have investigated in detail which factors influence activities of daily living (ADL) in adults with intellectual disabilities (ID) comorbid with/without dementia conditions. The objective of the present study was to describe the relation between early onset dementia conditions and progressive loss of ADL capabilities and to examine the influence of dementia conditions and other possible factors toward ADL scores in adults with ID. This study was part of the "Healthy Aging Initiatives for Persons with an Intellectual Disability in Taiwan: A Social Ecological Approach" project. We analyzed data from 459 adults aged 45 years or older with an ID regarding their early onset symptoms of dementia and their ADL profile based on the perspective of the primary caregivers. Results show that a significant negative correlation was found between dementia score and ADL score in a Pearson's correlation test (r=-0.28, pgender (β=4.187, peducation level (primary: β=5.544, phigh or more: β=8.147, pdisability level (β=-6.725, pDisability level and comorbidity can explain 10% of the ADL score variation, whereas dementia conditions can only explain 3% of the ADL score variation in the study. The present study highlights that future studies should scrutinize in detail the reasons for the low explanatory power of dementia for ADL, particularly in examining the appropriateness of the measurement scales for dementia and ADL in aging adults with ID.

    Several genetic disorders can present in adult patients with renal insufficiency. Genetic renal disease other than ADPKD accounts for ESRD in 3% of the adult Dutch population. Because of this low prevalence and their clinical heterogeneity most adult nephrologists are less familiar with these disord

    Full Text Available Abstract Background Advances in medical science have enabled many children with chronic diseases to survive to adulthood. The transition of adult patients with childhood-onset chronic diseases from pediatric to adult healthcare systems has received attention in Europe and the United States. We conducted a questionnaire survey among 41 pediatricians at pediatric hospitals and 24 nurses specializing in adolescent care to compare the perception of transition of care from pediatric to adult healthcare services for such patients. Findings Three-fourths of the pediatricians and all of the nurses reported that transition programs were necessary. A higher proportion of the nurses realized the necessity of transition and had already developed such programs. Both pediatricians and nurses reported that a network covering the transition from pediatric to adult healthcare services has not been established to date. Conclusions It has been suggested that spreading the importance of a transition program among pediatricians and developing a pediatric-adult healthcare network would contribute to the biopsychosocial well-being of adult patients with childhood-onset chronic disease.

    To develop recommendations on the transition from pediatric care to adult care in patients with chronic inflammatory rheumatic diseases with childhood onset based. Recommendations were generated following nominal group methodology and Delphi technique. A panel of 16 experts was established. A systematic literature review (on transitional care) and a narrative review were performed and presented to the panel in the first panel meeting to be discussed. A first draft of recommendations was generated and circulated. Focal groups with adolescents, young adults and parents were organized. In a second meeting, the focus group results along with the input from invited psychologist were used to establish definitive recommendations. Then, a Delphi process (two rounds) was carried out. A group of 72 pediatric and adult rheumatologists took part. Recommendations were voted from 1 (total disagreement) to 10 (total agreement). We defined agreement if at least 70 % voted ≥7. The level of evidence and grade or recommendation was assessed using the Oxford center for evidence-based medicine levels of evidence. Transition care was defined as a purposeful, planned process that addresses the medical, psychosocial and educational/vocational needs of adolescents and young adults with chronic inflammatory rheumatic diseases with childhood onset as they move from child-centered to adult-oriented healthcare systems. The consensus covers: transition needs, barriers and facilitators, transitional issues (objectives, participants, content, phases, timing, plans, documentation and responsibilities), physicians' and other health professionals' knowledge and skill requirements, models/programs, and strategies and guideline for implementation. Preliminary recommendations and agreement grade are shown in the Table (first Delphi round). These recommendations are intended to provide health professionals, patients, families and other stakeholders with a consensus on the transition process from

    Adult Swiss albino mice weighing 16+-1 g were injected with 3.7x10/sup 4/ Bq and 7.4x10/sup 4/ Bq/g body weight of /sup 45/Ca. Mice of both dose groups were autopsied on days 1, 3, 5, 7, 14 and 28 after /sup 45/Ca administration. Diaphragm and gastrocnemius in the /sup 45/Ca-treated and normal mice were analyzed for quantitation of glycogen as well as bioassay of phosphorylase and phosphohexose isomerase activities. Internal irradiation with the two doses of /sup 45/Ca resulted in glycogen accumulation in both the muscles. /sup 45/Ca-treated diaphragm showed greater radioresponse but a slower recovery than gastrocnemius with respect to glycogen accumulation. A decline in the rates of glycogenolysis and glycolysis indicated by decreased phosphorylase and phosphohexose isomerase activities appeared to be responsible for glycogen accumulation in skeletal muscle on account of /sup 45/Ca treatment.

    The characteristic rash of systemic juvenile idiopathic arthritis is a transient erythematous eruption associated with a quotidian spiking fever. Usually asymptomatic, it can be pruritic, with dermatographism at sites of scratching or pressure. An illness similar to this entity in adults is designated adult-onset Still disease. The relationship between the pediatric and adult disease is uncertain and differences in case definition have evolved. Specifically, a sustained arthritis for at least 6 weeks is required for a diagnosis of systemic juvenile idiopathic arthritis, whereas transient arthritis and arthralgia are accepted criteria in adult-onset Still disease. We describe five patients less than 16 years of age who presented with an acute illness characterized by fever and a distinctive skin eruption. Intense pruritus and linear erythematous lesions flared with a spiking fever, usually in the late afternoon and evening. Periorbital edema/erythema and nonlinear urticarial lesions were also seen. Two children had splinter hemorrhages of the nail beds and one girl developed a fixed, scaling, pigmented, linear eruption. Severe malaise, myalgia, arthralgia, and leukocytosis were present in every patient. Other systemic manifestations included sore throat, transient arthritis, abdominal pain, lymphadenopathy, hepatomegaly, splenomegaly, hyperferritinemia, and hepatic dysfunction. No patient had a sustained arthritis. The course of the disease was variable. One patient, diagnosed with macrophage activation syndrome, recovered on oral naproxen. Two patients responded to systemic corticosteroid therapy. One girl developed status epilepticus and died from aspiration and asphyxia. A boy with severe hepatitis developed renal failure and thrombotic thrombocytopenic purpura and was treated with plasmapheresis, dialysis, and systemic corticosteroids; he had recurrent episodes of rash and fever into adult life. These children did not fulfill the case definition of systemic

    We herein report the case of a previously healthy 24-year-old Japanese woman who developed adult-onset clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) presenting with hemiparesis and hemianesthesia secondary to adenovirus infection. The patient's neurological symptoms and the lesion in the splenium resolved within 17 days without therapy. The radiographic features and clinical course observed in this case were consistent with a diagnosis of MERS; however, the only neurological symptoms were hemiparesis and hemianesthesia. This is the first reported case of MERS involving only hemiparesis and hemianesthesia at onset. This case suggests that a diagnosis of MERS should be suspected in patients with hemiparesis and hemianesthesia, especially when these conditions are preceded by infection.

    We report a new family with autosomal dominant inheritance of a late onset rapidly progressive leukodystrophy in which exome sequencing has revealed a novel mutation p.R782G in the Colony-Stimulating Factor 1 Receptor gene (CSF1R). Neuropathology of two affected family members showed cerebral white matter degeneration with axonal swellings and pigmented macrophages. The few recently reported families with CSF1R mutations had been previously labelled "hereditary diffuse leukencephalopathy with axonal spheroids" (HDLS) and "pigmentary orthochromatic leukodystrophy" (POLD), disorders which now appear to form a disease continuum. The term "adult-onset leukoencephalopathy with axonal spheroids and pigmented glia" (ALSP) has been proposed to encompass this spectrum. As CSF1R regulates microglia this mutation implies that dysregulation of microglia is the primary cause of the disease.

    There is ample data suggesting that individuals with bipolar disorder more frequently suffer from disturbed sleep even when euthymic. Since sleep is a process that is crucial for affective homeostasis, disturbed sleep in healthy individuals may be a risk factor for the subsequent onset of bipolar disorder. Utilizing data from a large cohort of adolescents and young adults, this study tests the hypothesis that disturbed sleep constitutes a risk factor for the later onset of bipolar disorder. A representative community sample of N = 3021 adolescents and young adults (baseline age 14-24) was assessed using the standardized Composite International Diagnostic Interview and followed-up prospectively up to 3 times over up to 10 years. Disturbed sleep at baseline was quantified utilizing the corresponding items from the self-report inventory SCL-90-R. The compound value (insomnia-score) as an ordinal parameter for the severity of sleep disturbances was used to assess associations with the incidence of bipolar disorder among participants free of major mental disorder at baseline (N = 1943) using odds ratios (OR) from logistic regressions. Analyses were adjusted for age, gender, parental mood disorder and lifetime alcohol or cannabis dependence. Poor sleep quality significantly increased the risk for the subsequent development of bipolar disorder (OR = 1.75; p = 0.001). Regarding individual sleep items, trouble falling asleep and early morning awakening were predictive for the subsequent onset of bipolar disorder. Disturbed sleep in persons otherwise free of major mental disorders appears to confer an increased risk for the subsequent onset of bipolar disorder. Copyright © 2015 Elsevier Ltd.

    Extensive epidemiologic research from the United States demonstrates that childhood adversities (CAs) are predictive of several psychiatric outcomes, including depression, anxiety, substance abuse, and externalizing disorders. To date, this has not been explored in a national sample of adults in South Africa. The present study examined the joint predictive effects of 11 retrospectively reported CAs on the first onset of DSM-IV disorders in the South Africa Stress and Health Study (SASH), a nationally representative sample of adults. We utilized substantively plausible regression models of joint CA effects that account for the comorbidity between individual CAs; outcomes included DSM-IV anxiety disorders, mood disorders, substance use disorders, and externalizing disorders measured with the WHO Composite International Diagnostic Interview. The results indicated that experiences of CA varied by race, and many CAs were correlated with one another. The best-fitting model for first onset of any disorder included separate indicators for each type of CA, in addition to indicator variables for the number of other CAs reported. Results disaggregated by class of disorder showed that the majority of CAs with significant odds ratios only predicted anxiety disorder. Results disaggregated by life course stage of first onset showed that significant effects of CAs can be observed at each stage of the life course. This study contributes to a growing body of research on the social determinants of mental health in South Africa. Our findings illustrate the importance of utilizing a model that accounts for the clustering and accumulation of CAs, and suggest that a variety of CAs predict onset of mental disorders, particularly anxiety disorders, at several stages of the life course.

    Glycosylation changes in patients with juvenile chronic and adult onset rheumatoid arthritis have been studied using a novel binding method. Both these major types of arthritis showed decreased galactosylation of serum IgG, which confirms earlier studies using a different, more complex chemical method. No significant correlation between serum IgG, IgM, and IgA rheumatoid factors and age corrected G(o) (percentage of oligosaccharide chains lacking galactose) was found. The possibility that the less glycosylated IgG is preferentially confined to circulating IgM/IgG immune complexes cannot be excluded, however.

  13. Kinetic analysis of glycogen turnover: relevance to human brain 13C-NMR spectroscopy.

    A biophysical model of the glycogen molecule is developed, which takes into account the points of attack of synthase and phosphorylase at the level of the individual glucose chain. Under the sole assumption of steric effects governing enzyme accessibility to glucosyl residues, the model reproduces the known equilibrium structure of cellular glycogen at steady state. In particular, experimental data are reproduced assuming that synthase (1) operates preferentially on inner chains of the molecule and (2) exhibits a faster mobility than phosphorylase in translocating from an attacked chain to another. The model is then used to examine the turnover of outer versus inner tiers during the labeling process of isotopic enrichment (IE) experiments. Simulated data are fitted to in vivo (13)C nuclear magnetic resonance spectroscopy measurements obtained in the human brain under resting conditions. Within this experimental set-up, analysis of simulated label incorporation and retention shows that 7% to 35% of labeled glucose is lost from the rapidly turning-over surface of the glycogen molecule when stimulation onset is delayed by 7 to 11.5 hours after the end of [1-(13)C]glucose infusion as done in actual procedures. The substantial label washout before stimulation suggests that much of the subsequent activation-induced glycogenolysis could remain undetected. Overall, these results show that the molecular structure significantly affects the patterns of synthesis and degradation of glycogen, which is relevant for appropriate design of labeling experiments aiming at investigating the functional roles of this glucose reserve.

    Glucose is the main fuel for energy metabolism in retina. The regulatory mechanisms that maintain glucose homeostasis in retina could include hormonal action. Retinopathy is one of the chemical manifestations of long-standing diabetes mellitus. In order to better understand the effect of hyperglycemia in retina, we studied glycogen content as well as glycogen synthase and phosphorylase activities in both normal and streptozotocin-induced diabetic rat retina and compared them with other tissues. Glycogen levels in normal rat retina are low (46 +/- 4.0 nmol glucosyl residues/mg protein). However, high specific activity of glycogen synthase was found in retina, indicating a substantial capacity for glycogen synthesis. In diabetic rats, glycogen synthase activity increased between 50% and 100% in retina, brain cortex and liver of diabetic rats, but only retina exhibited an increase in glycogen content. Although, total and phosphorylated glycogen synthase levels were similar in normal and diabetic retina, activation of glycogen synthase by glucose-6-P was remarkable increased. Glycogen phosphorylase activity decreased 50% in the liver of diabetic animals; it was not modified in the other tissues examined. We conclude that the increase in glycogen levels in diabetic retina was due to alterations in glycogen synthase regulation.

    Glycogen is important not only for the energy supplementary of oysters, but also for human consumption. High glycogen content can improve the stress survival of oyster. A key enzyme in glycogenesis is glycogen synthase that is encoded by glycogen synthase gene GYS. In this study, the relationship between single nucleotide polymorphisms (SNPs) in coding regions of Crassostrea gigas GYS (Cg-GYS) and individual glycogen content was investigated with 321 individuals from five full-sib families. Single-strand conformation polymorphism (SSCP) procedure was combined with sequencing to confirm individual SNP genotypes of Cg-GYS. Least-square analysis of variance was performed to assess the relationship of variation in glycogen content of C. gigas with single SNP genotype and SNP haplotype. As a consequence, six SNPs were found in coding regions to be significantly associated with glycogen content ( P polymorphism on the glycogen content and provided molecular biological information for the selective breeding of good quality traits of C. gigas.

    Bin Deng

    Full Text Available Glycogen is a highly branched glucose polymer which is involved in maintaining blood-sugar homeostasis. Liver glycogen contains large composite α particles made up of linked β particles. Previous studies have shown that the binding which links β particles into α particles is impaired in diabetic mice. The present study reports the first molecular structural characterization of human-liver glycogen from non-diabetic patients, using transmission electron microscopy for morphology and size-exclusion chromatography for the molecular size distribution; the latter is also studied as a function of time during acid hydrolysis in vitro, which is sensitive to certain structural features, particularly glycosidic vs. proteinaceous linkages. The results are compared with those seen in mice and pigs. The molecular structural change during acid hydrolysis is similar in each case, and indicates that the linkage of β into α particles is not glycosidic. This result, and the similar morphology in each case, together imply that human liver glycogen has similar molecular structure to those of mice and pigs. This knowledge will be useful for future diabetes drug targets.

    Epinephrine increases glycogen synthase (GS) phosphorylation and decreases GS activity but also stimulates glycogen breakdown, and low glycogen content normally activates GS. To test the hypothesis that glycogen content directly regulates GS phosphorylation, glycogen breakdown was stimulated in condition with decreased GS activation. Saline or epinephrine (0.02 mg/100 g rat) was injected subcutaneously in Wistar rats (∼130 g) with low (24-h-fasted), normal (normal diet), and high glycogen content (fasted-refed), and epitrochlearis muscles were removed after 3 h and incubated ex vivo, eliminating epinephrine action. Epinephrine injection reduced glycogen content in epitrochlearis muscles with high (120.7 ± 17.8 vs. 204.6 ± 14.5 mmol/kg, P < 0.01) and normal glycogen (89.5 ± 7.6 vs. 152 ± 8.1 mmol/kg, P < 0.01), but not significantly in muscles with low glycogen (90.0 ± 5.0 vs. 102.8 ± 7.8 mmol/kg, P = 0.17). In saline-injected rats, GS phosphorylation at sites 2+2a, 3a+3b, and 1b was higher and GS activity lower in muscles with high compared with low glycogen. GS sites 2+2a and 3a+3b phosphorylation decreased and GS activity increased in muscles where epinephrine decreased glycogen content; these parameters were unchanged in epitrochlearis from fasted rats where epinephrine injection did not decrease glycogen content. Incubation with insulin decreased GS site 3a+3b phosphorylation independently of glycogen content. Insulin-stimulated glucose uptake was increased in muscles where epinephrine injection decreased glycogen content. In conclusion, epinephrine stimulates glycogenolysis in epitrochlearis muscles with normal and high, but not low, glycogen content. Epinephrine-stimulated glycogenolysis decreased GS phosphorylation and increased GS activity. These data for the first time document direct regulation of GS phosphorylation by glycogen content.

    Lafora disease (LD) is a fatal progressive myoclonus epilepsy characterized neuropathologically by aggregates of abnormally structured glycogen and proteins (Lafora bodies, LB), and neurodegeneration. Whether LB could be prevented by inhibiting glycogen synthesis and whether they are pathogenic remain uncertain. We genetically eliminated brain glycogen synthesis in LD mice. This resulted in long-term prevention of LB formation, neurodegeneration, and seizure susceptibility. This study establishes that glycogen synthesis is requisite for LB formation and that LB are pathogenic. It opens a therapeutic window for potential treatments in LD with known and future small molecule inhibitors of glycogen synthesis. PMID:23913475

    We report the clinical, biochemical, and molecular genetic findings in a family with an unusual mitochondrial disease phenotype harboring a novel mtDNA tRNA glutamic acid mutation at position 14709. The proband and his sister presented with congenital myopathy and mental retardation and subsequently developed cerebellar ataxia. Other family members had either adult-onset diabetes mellitus with muscle weakness or adult-onset diabetes mellitus alone. Ragged-red and cytochrome c oxidase (COX)-negative fibers were present in muscle biopsies. Biochemical studies of muscle mitochondria showed reduced complex I and IV activities. The mtDNA mutation was heteroplasmic in blood and muscle in all matrilineal relatives analyzed. Primary myoblast, but not fibroblast, cultures containing high proportions of mutant mtDNA exhibited impaired mitochondrial translation. These observations indicate that mtDNA tRNA point mutations should be considered in the differential diagnosis of congenital myopathy. In addition they illustrate the diversity of phenotypes associated with this mutation in the same family and further highlight the association between mtDNA mutations and diabetes mellitus. 43 refs., 4 figs., 1 tab.

    Recently, some reports have indicated that limbic encephalitis associated with anti-voltage-gated potassium channel complex antibodies (VGKC-Ab) is a cause of adult-onset mesial temporal lobe epilepsy (MTLE). We report a 53-year-old woman who had her first epileptic seizure at the age of 50 years old. Examination by 3-Tesla brain MRI revealed left hippocampal high signal intensity and swelling on fluid-attenuated inversion recovery (FLAIR) and T2-weighted imaging at 2 months after her first seizure. The patient received intravenous methylprednisolone and carbamazepine 300 mg/day. One month later, MRI revealed improvement of her left hippocampal abnormalities. Thereafter, she had no seizures, however, three years after her first seizure, EEG revealed a seizure pattern in the left temporal region. Brain MRI revealed left hippocampal high signal intensity and brain fluorodeoxyglucose positron emission tomography revealed hypermetabolism. Her serum VGKC-Ab levels were 118 pM(normal VGKC-Ab levels decreased to 4.4 pM. Remission of the epileptic seizures was also observed. This MTLE in the middle age was considered as limbic encephalitis associated with anti- VGKC-Ab. In cases of unexplained adult-onset MTLE, limbic encephalitis associated with anti-VGKC-Ab, which responds well to immunotherapy, should be considered in the differential diagnosis.

    We herein report a 32-year-old woman with adult-onset reducing body myopathy (RBM) who had a mutation in the four-and-a-half LIM domain 1 gene (FHL1) and showed a marked asymmetrical involvement of sternocleidomastoid and trapezius muscles. At 30 years of age she noticed bilateral foot drop, and over the next two years developed difficulty raising her right arm. At 32 years of age she was admitted to our hospital for a diagnostic evaluation. Neurological examination showed moderate weakness and atrophy of her right sternocleidomastoid muscle, right trapezius muscle, and bilateral upper proximal muscles. There were severe weakness and atrophy of her bilateral tibialis anterior muscles. Her deep tendon reflexes were hypoactive in her upper extremities. Her serum creatine kinase level was mildly increased. Muscle biopsy specimens from the left tibialis anterior muscle revealed marked variation in fiber size, some necrotic or regenerating fibers, and reducing bodies. Gene analysis of FHL1 demonstrated a mutation: a heterozygous missense mutation of c.377G>A (p. C126T) in FHL1. Compared with previous adult-onset RBM cases harboring mutations in FHL1, our case was characterized by asymmetrical atrophy of the sternocleidomastoid and trapezius muscles.

    Full Text Available Background: It is estimated that one in four persons with young-onset dementia (YOD (<65 years old has children younger than 18 years old at the onset of the dementia. These children experience a childhood different from what is expected. Adult children of parents with YOD are seldom addressed in research, and the impact of the dementia on the children's development over time has rarely been studied. Aim: The goal of this study was to explore how adult children experienced the influence of their parents’ dementia on their own development during adolescence; what coping efforts, strategies, and resources they employed; and how they evaluated the most recent changes in their life situation. Method: A follow-up, grounded theory approach in two phases was used. Qualitative interviews with 14 informants (18–30 years of age were conducted in 2014 and one year later, in 2015. Findings: Nearly all the informants expressed that their emotional well-being and their life situation were better at the second interview compared to the time of dementia onset in their parents. To overcome the difficulties of being a child of a parent with YOD, they used different instrumental, cognitive, and emotional coping strategies, subsumed analytically under the concept detachment. This category covers three subcategories of coping strategies: moving apart, greater personal distance, and calmer emotional reactions. Another category, resilience, designates combinations of the coping strategies. Vital for the development of coping resources and resilience was the need the informants had for social support—for people they saw who listened to them and responded to their needs. Conclusion: Most of the informants reported that they experienced a better life situation and less emotional stress over time as their parent's dementia progressed. They developed better coping capacities and greater resilience. Vital for the development of coping resources and resilience was the

    To demonstrate the safety and effectiveness of responsive stimulation at the seizure focus as an adjunctive therapy to reduce the frequency of seizures in adults with medically intractable partial onset seizures arising from one or two seizure foci. Randomized multicenter double-blinded controlled trial of responsive focal cortical stimulation (RNS System). Subjects with medically intractable partial onset seizures from one or two foci were implanted, and 1 month postimplant were randomized 1:1 to active or sham stimulation. After the fifth postimplant month, all subjects received responsive stimulation in an open label period (OLP) to complete 2 years of postimplant follow-up. All 191 subjects were randomized. The percent change in seizures at the end of the blinded period was -37.9% in the active and -17.3% in the sham stimulation group (p = 0.012, Generalized Estimating Equations). The median percent reduction in seizures in the OLP was 44% at 1 year and 53% at 2 years, which represents a progressive and significant improvement with time (p < 0.0001). The serious adverse event rate was not different between subjects receiving active and sham stimulation. Adverse events were consistent with the known risks of an implanted medical device, seizures, and of other epilepsy treatments. There were no adverse effects on neuropsychological function or mood. Responsive stimulation to the seizure focus reduced the frequency of partial-onset seizures acutely, showed improving seizure reduction over time, was well tolerated, and was acceptably safe. The RNS System provides an additional treatment option for patients with medically intractable partial-onset seizures. © 2014 The Authors.

    The involvement of brain glycogen in sustaining neuronal activity has previously been demonstrated. However, to what extent energy derived from glycogen is consumed by astrocytes themselves or is transferred to the neurons in the form of lactate for oxidative metabolism to proceed is at present...... in co-cultures of cerebellar neurons and astrocytes. In the astrocytes it was shown that uptake of the glutamate analogue D-[3H]aspartate was impaired when glycogen degradation was inhibited irrespective of the presence of glucose, signifying that energy derived from glycogen degradation is important...... for the astrocytic compartment. By inhibiting glycogen degradation in co-cultures it was evident that glycogen provides energy to sustain glutamatergic neurotransmission, i.e. release and uptake of glutamate. The relocation of glycogen derived lactate to the neuronal compartment was investigated by employing d...

  13. Glutamic acid decarboxylase antibodies are indicators of the course, but not of the onset, of diabetes in middle-aged adults: the Atherosclerosis Risk in Communities Study

    Full Text Available To efficiently examine the association of glutamic acid decarboxylase antibody (GADA positivity with the onset and progression of diabetes in middle-aged adults, we performed a case-cohort study representing the ~9-year experience of 10,275 Atherosclerosis Risk in Communities Study participants, initially aged 45-64 years. Antibodies to glutamic acid decarboxylase (GAD65 were measured by radioimmunoassay in 580 incident diabetes cases and 544 non-cases. The overall weighted prevalence of GADA positivity (³1 U/mL was 7.3%. Baseline risk factors, with the exception of smoking and interleukin-6 (P £ 0.02, were generally similar between GADA-positive and -negative individuals. GADA positivity did not predict incident diabetes in multiply adjusted (HR = 1.04; 95%CI = 0.55, 1.96 proportional hazard analyses. However, a small non-significant adjusted risk (HR = 1.29; 95%CI = 0.58, 2.88 was seen for those in the highest tertile (³2.38 U/mL of positivity. GADA-positive and GADA-negative non-diabetic individuals had similar risk profiles for diabetes, with central obesity and elevated inflammation markers, aside from glucose, being the main predictors. Among diabetes cases at study's end, progression to insulin treatment increased monotonically as a function of baseline GADA level. Overall, being GADA positive increased risk of progression to insulin use almost 10 times (HR = 9.9; 95%CI = 3.4, 28.5. In conclusion, in initially non-diabetic middle-aged adults, GADA positivity did not increase diabetes risk, and the overall baseline profile of risk factors was similar for positive and negative individuals. Among middle-aged adults, with the possible exception of those with the highest GADA levels, autoimmune pathophysiology reflected by GADA may become clinically relevant only after diabetes onset.

    To investigate the clinical characteristics and pathogens of community-onset bacteremia among human immunodeficiency virus (HIV)-infected adults as well as to establish the clinical predictors of the major microorganisms. An observational cohort study was conducted retrospectively between January 2007 and December 2012. Demographic characteristics and pathogens determined from chart records were analyzed. Of the 121 eligible HIV adults with bacteremia, there was a male predominance (106 patients, 87.6%); elderly individuals (age ≥ 65 years) accounted for only 2.5% of the study population (3 patients). Of the total microorganisms isolated (n=123), Staphylococcus aureus (55, 44.7%) and Salmonella enterica (17, 13.8%) were the common pathogens. In a multivariate analysis, the leading two significant predictors of S. aureus infection were infective endocarditis (odds ratio, 11.49; p=0.001) and transmission risk with injection drug users (IDUs; odds ratio, 6.22; p=0.001). In addition, transmission risk with men who have sex with men (MSM; odds ratio, 37.49; p=0.001) was the leading clinical predictor of S. enterica infection. In further analyses, a strong linear-by-linear correlation between S. aureus infection and IDU (γ=0.94, p=0.02) as well as between S. enterica infection and MSM (γ=0.96, p=0.01) was evidenced. Focusing on the two key pathogens in HIV-infected adults with community-onset bacteremia, IDU was one of independent predictors associated with S. aureus infection, whereas MSM was the leading risk factor of S. enterica infection. Although the proposed predictive model of these pathogens has been not established, a scoring system involving the transmission risk of HIV may be of use for the early identification of these patients for clinicians.

    Adrenaline increases glycogen synthase (GS) phosphorylation and decreases GS activity but also stimulates glycogen breakdown and low glycogen content normally activates GS. To test the hypothesis that glycogen content directly regulates GS phosphorylation, glycogen breakdown was stimulated...... in condition with decreased GS activation. Saline or adrenaline (0.02mg/100g rat) was injected subcutaneously in Wistar rats (~130 g) with low (24 h fasted), normal (normal diet) and high glycogen content (fasted-refed) and epitrochlearis muscles were removed after 3 h and incubated ex vivo eliminating...... adrenaline action.

    2012-10-01

    To evaluate the safety, efficacy, pharmacokinetics, pharmacodynamic properties, and clinical application of ezogabine (retigabine, INN), an antiepileptic drug approved in 2011. Published data from in vitro, animal, and clinical studies were obtained from PubMed and CINAHL searches, from January 1980 to March 31, 2012. Other relevant data regarding the safety and efficacy of ezogabine were obtained from the Food and Drug Administration and the European Medication Agency Web sites. Selected articles were prospective in vitro, animal, and controlled clinical studies of ezogabine. Non-English-language articles were excluded. In vitro and animal studies show that ezogabine activates voltagegated potassium channels, leading to reduction of seizure frequency by inhibiting hyperexcitability activity in the central nervous system. Additionally, ezogabine enhances γ-aminobutyric acid (GABA) activity and de novo GABA synthesis. Eight clinical studies of ezogabine have been published, 5 being Phase 1 clinical trials in healthy subjects and 3 being Phase 3 clinical trials in patients with pharmaco-resistant partial-onset seizures. Phase 3 clinical trials demonstrated the safety and efficacy of ezogabine in patients with partial-onset seizures. Clinical trials have shown that ezogabine is efficacious as an adjunctive agent in patients with pharmacoresistant partial seizures. Careful monitoring of drug interactions and adverse reactions is necessary. While ezogabine is efficacious for partial seizures, its precise role in the management of patients with epilepsy is yet to be determined.

    The objective of this pilot study is to investigate the relation between asthma and wheeze debut and individually estimated exposure to traffic-related air pollutants with a validated exposure system (AirGIS). A non-smoking cohort with recently acquired asthma or wheeze as well as matched controls was identified from a large cross-sectional study. All residential and working addresses with corresponding time periods for a 10 year period were successfully identified for all study participants (N=33) and exposure estimated for both urban background and street level. Individual levels of air pollutants in the years preceding debut of asthma or wheeze were analyzed using survival analysis. No significant correlations between exposure levels and onset of disease or symptom were demonstrated. A tendency towards higher levels of nitrogen oxides exposure during the year prior to debut was seen in wheeze cases. Substantial problems in determining time of onset were encountered. It is recommended that the analytic methods developed in this pilot study are used in a larger prospective cohort to investigate individual trafficrelated air pollutants as a risk factor for the development of new asthma and wheeze.

    2000-01-01

    There is increasing evidence that endogenous glycogen depletion may affect excitation-contraction (E-C) coupling events in vertebrate skeletal muscle. One approach employed in physiological investigations of E-C coupling involves the use of mechanically skinned, single fibre preparations obtained from tissues stored under paraffin oil, at room temperature (RT: 20-24 degrees C) and 4 degrees C for several hours. In the present study, we examined the effect of these storage conditions on the glycogen content in three muscles frequently used in research on E-C coupling: rat extensor digitorum longus (EDL) and soleus (SOL) and toad iliofibularis (IF). Glycogen content was determined fluorometrically in homogenates prepared from whole muscles, stored under paraffin oil for up to 6 h at RT or 4 degrees C. Control muscles and muscles stored for 0.5 and 6 h were also analysed for total phosphorylase (Phos(total)) and phosphorylase a (Phos a) activities. No significant change was observed in the glycogen content of EDL and SOL muscles stored at RT for 0.5 h. In rat muscles stored at RT for longer than 0.5 h, the glycogen content decreased to 67.6% (EDL) and 78.7% (SOL) of controls after 3 h and 25.3% (EDL) and 37.4% (SOL) after 6 h. Rat muscles stored at 4 degrees C retained 79.0% (EDL) and 92.5% (SOL) of glycogen after 3 h and 75.2% (EDL) and 61.1% (SOL) after 6 h. The glycogen content of IF muscles stored at RT or 4 degrees C for 6 h was not significantly different from controls. Phos(total) was unchanged in all muscles over the 6 h period, at both temperatures. Phos a was also unchanged in the toad IF muscles, but in rat muscles it decreased rapidly, particularly in EDL (4.1-fold after 0.5 h at RT). Taken together these results indicate that storage under paraffin oil for up to 6 h at RT or 4 degrees C is accompanied by minimal glycogen loss in toad IF muscles and by a time- and temperature-dependent glycogen loss in EDL and SOL muscles of the rat.

    2015-05-01

    Glycogen synthase kinase-3 (GSK3) is a constitutively active serine threonine kinase with 1) two isoforms (GSK3A and GSK3B) that have unique and overlapping functions, 2) multiple molecular intracellular mechanisms that involve phosphorylation of diverse substrates, and 3) implications in pathogenesis of many diseases. Insulin causes phosphorylation and inactivation of GSK3 and mammalian oocytes have a functional insulin-signaling pathway whereby prolonged elevated insulin during follicle/oocyte development causes GSK3 hyperphosphorylation, reduced GSK3 activity, and altered oocyte chromatin remodeling. Periconceptional diabetes and chronic hyperinsulinemia are associated with congenital malformations and onset of adult diseases of cardiovascular origin. Objectives were to produce transgenic mice with individual or concomitant loss of GSK3A and/or GSK3B and investigate the in vivo role of oocyte GSK3 on fertility, fetal development, and offspring health. Wild-type males bred to females with individual or concomitant loss of oocyte GSK3 isoforms did not have reduced fertility. However, concomitant loss of GSK3A and GSK3B in the oocyte significantly increased neonatal death rate due to congestive heart failure secondary to ventricular hyperplasia. Individual loss of oocyte GSK3A or GSK3B did not induce this lethal phenotype. In conclusion, absence of oocyte GSK3 in the periconceptional period does not alter fertility yet causes offspring cardiac hyperplasia, cardiovascular defects, and significant neonatal death. These results support a developmental mechanism by which periconceptional hyperinsulinemia associated with maternal metabolic syndrome, obesity, and/or diabetes can act on the oocyte and affect offspring cardiovascular development, function, and congenital heart malformation.

    2016-10-01

    Full Text Available Introduction: The clinical and histological presentations of the adult form of Pompe disease may be atypical. In such cases, identifying histological signs that point to the diagnosis would be crucial to avoid a delay in care. The aim of our study was to investigate the presence of rimmed vacuoles and acid phosphatase positivity in muscle biopsies of patients with late-onset Pompe disease. Material and methods: We retrospectively studied muscle biopsies of all cases of the adult form of Pompe disease diagnosed at the University Hospital of Caen. Three of these four cases showed atypical clinical signs, and diagnosis was established tardily based on family history or systematic analysis of acid maltase activity. Results: All biopsies showed some rimmed vacuoles. The acid phosphatase reaction showed positive inclusions and labelled vacuoles in biopsies of all patients. Conclusions: The presence of rimmed vacuoles and acid phosphatase positivity in muscle biopsy should suggest the diagnosis of the adult form of Pompe disease, this is decisive since effective therapy is available.

    The fat mass and obesity-associated (FTO) gene is known to be associated with obesity. However, no data are available on the relation between FTO rs9930506 polymorphism and obesity in Polish population. The aim of this study was to evaluate an association between rs9930506 variants of the FTO gene and obesity in Polish adults. The study group consisted of 442 adults, aged 33.9 ±12.7 yr, with mean BMI 27.2 ± 5.4 kg/m2. The following variables were determined for each subject: fasting blood glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides. Real-time PCR was used to detect the A/G alleles of the rs9939506 polymorphism in the FTO gene. An association between the rs9930506 polymorphism and obesity was determined using codominant, dominant, and recessive models. The odds ratio (OR) was calculated to determine the risk of obesity associated with this polymorphism. It was observed that the presence of FTO rs9939506 G allele was associated with increased risk for obesity and this association was found significant in both recessive (OR = 1.72, P = 0.014) and co-dominant (OR = 1.36, P = 0.031) models of inheritance. The FTO rs9939506 GG homozygotes had a significantly higher BMI than those with other genotypes. This study shows that FTO rs9939506 GG genotype is related to higher BMI and is associated with obesity in Polish adults.

    Full Text Available A 34 year-old Afro-Caribbean female presented with recurring episodes of fever and lower abdominal pain over a period of two months not improving despite courses of antibiotics for possible recurrent urinary tract infections. On admission to hospital, patient was treated for a possible pyelonephritis or pelvic inflammatory disease (PID. Extensive investigations into possible source of infection were carried out. However, all of the repeated microbiological cultures were normal. Patient was investigated further for other possible causes including connective tissue disease, haematological disorders, or neoplasm, all of which were normal. Diagnosis of adult onset Still’s disease (AOSD was confirmed by a rheumatologist based on Yamaguchi’s diagnostic criteria for AOSD alongside significantly raised serum ferritin. Patient was treated with steroids to which she showed remarkable clinical improvement alongside marked reduction in her serum ferritin levels.

    The ataxias are a complex group of diseases with both environmental and genetic causes. Among the autosomal dominant forms of ataxia the genes for two, spinocerebellar ataxia type 1 (SCA1) and Machado-Joseph disease (MJD), have been isolated. In both of these disorders the molecular basis of disease is the expansion of an unstable CAG trinucleotide repeat. To assess the frequency of the SCA1 and MJD trinucleotide repeat expansions among individuals diagnosed with ataxia, we have collected DNA from individuals representing 311 families with adult-onset ataxia of unknown etiology and screened these samples for trinucleotide repeat expansions within the SCA1 and MJD genes. Within this group there are 149 families with dominantly inherited ataxia. Of these, 3% have SCA1 trinucleotide repeat expansions, whereas 21% were positive for the MJD trinucleotide expansion. Thus, together SCA1 and MJD represent 24% of the autosomal dominant ataxias in our group, and the frequency of MJD is substantially greater than that of SCA1. For the 57 patients with MJD trinucleotide repeat expansions, a strong inverse correlation between CAG repeat size and age at onset was observed (r = -.838). Among the MJD patients, the normal and affected ranges of CAG repeat size are 14-40 and 68-82 repeats, respectively. For SCA1 the normal and affected ranges are much closer, containing 19-38 and 40-81 CAG repeats, respectively. 30 refs., 1 fig., 3 tabs.

    Synchronous spinal intradural ependymal cysts and sacral Tarlov cysts in adult onset tethered cord syndrome are extremely rare. A 23-year-old male presented with back pain radiating into both lower extremities, accompanied by acute onset of gait difficulty and sphincter dysfunction. Magnetic resonance imaging identified a low lying conus medullaris, syringomyelia with septations extending from T12 to S1, a tethered cord, and a thickened filum terminale with a sacral Tarlov cyst. The patient underwent a L3-4 laminectomy for decompression of syringomyelia and excision/biopsy of a space occupying lesion along with S1-2 laminectomy for cord untethering and Tarlov cyst fenestration. Postoperative histopathology confirmed that the lesion was an ependymal cyst. Clinically, patient showed marked improvement in the neurological status. Simultaneous decompressive laminectomy of L3-4 and S1-2 effectively decompressed the syringomyelia while allowing for excision/biopsy of a space occupying lesion at the former and untethering and Tarlov cyst fenestration at the latter levels.

    Full text of the publication follows: Thyroid cancer is one of the malignancies most strongly associated with ionizing radiation in humans. Epidemiology studies of atomic bomb (A-bomb) survivors have indicated that excess relative risk of papillary thyroid cancer per Gy was remarkably high in the survivors. We therefore aim to clarify mechanisms linking A-bomb radiation exposure and development of papillary thyroid cancer. Toward this end, we intend to clarify characteristics of gene alterations occurring in radiation-associated adult-onset papillary thyroid cancer from the Life Span Study cohort of A-bomb survivors. We have thus far found that with increased radiation dose, papillary thyroid cancer cases with chromosomal rearrangements (mainly RET/PTC rearrangements) significantly increased and papillary thyroid cancer cases with point mutations (mainly BRAF-V600E) significantly decreased. Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

    Identification as well as a detailed analysis of glycogen in human milk has not been shown yet. The present study confirmed that glycogen is contained in human milk by qualitative and quantitative analyses. High-performance anion exchange chromatography (HPAEC) and high-performance size exclusion chromatography with a multiangle laser light scattering detector (HPSEC-MALLS) were used for qualitative analysis of glycogen in human milk. Quantitative analysis was carried out by using samples obtained from the individual milks. The result revealed that the concentration of human milk glycogen varied depending on the mother's condition-such as the period postpartum and inflammation. The amounts of glycogen in human milk collected at 0 and 1-2 months postpartum were higher than in milk collected at 3-14 months postpartum. In the milk from mothers with severe mastitis, the concentration of glycogen was about 40 times higher than that in normal milk.

    Full Text Available We present a case of new onset psychosis in the setting of thyroid storm in a woman with no previous psychiatric history. The patient presented with ongoing suicidal ideation, a suicide attempt that was interrupted by her husband, and audio and visual hallucinations. The patient was placed on a psychiatric hold and treated for thyrotoxicosis as well as psychosis. Treatment of the thyroid hormone overload resulted in a rapid resolution of her symptoms; she was discharged in excellent condition, and she has had no repeat hallucinations or self-injury ideation or attempts since. Although rare, thyrotoxicosis is a potentially life-threatening cause of psychiatric illness and should always be kept on the differential diagnosis for a patient with a first episode of psychosis. This case highlights how thyroid storm physiology, beyond its well-studied hemodynamic and metabolic instability, can be potentially fatal due to psychiatric sequelae. It also highlights the crucial role of a thorough history and physical exam in all patients.

    The speed of kill of afoxolaner against experimental infestations by Ctenocephalides felis was evaluated after oral administration of afoxolaner in a soft chew (NEXGARD(®)) at a dose to achieve 2.5mg/kg bodyweight. Forty beagles were allocated to two treatment groups. Dogs in Treatment Group 1 were untreated controls. Dogs in Treatment Group 2 were treated on Day-0 with afoxolaner, according to their pre-treatment bodyweight. All dogs were infested with approximately 100 C. felis on Day-1. Live fleas were counted upon removal at 5 time points after treatment (i.e., 2, 4, 8, 12 and 24h after treatment). For each time point, counts were performed on 4 dogs from each of the treated and the untreated groups. Early curative flea killing efficacy was evaluated with respect to the untreated control group. The afoxolaner treated group had significantly fewer fleas than the untreated control group at 8, 12, and 24h (pafoxolaner were 15.0%, 87.8%, 99.5%, 100.0%, and 100.0% at 2, 4, 8, 12, and 24h, respectively. In this study, afoxolaner began killing fleas by 2h after treatment with increasing efficacy at subsequent time points and had >99.5% efficacy at 8, 12, and 24h after treatment demonstrating an early onset of action.

    Full Text Available Duchenne muscular dystrophy (DMD is a severe, genetic muscle wasting disorder characterised by progressive muscle weakness. DMD is caused by mutations in the dystrophin (dmd gene resulting in very low levels or a complete absence of the dystrophin protein, a key structural element of muscle fibres which is responsible for the proper transmission of force. In the absence of dystrophin, muscle fibres become damaged easily during contraction resulting in their degeneration. DMD patients and mdx mice (an animal model of DMD exhibit altered metabolic disturbances that cannot be attributed to the loss of dystrophin directly. We tested the hypothesis that glycogen metabolism is defective in mdx dystrophic mice.Dystrophic mdx mice had increased skeletal muscle glycogen (79%, (P<0.01. Skeletal muscle glycogen synthesis is initiated by glycogenin, the expression of which was increased by 50% in mdx mice (P<0.0001. Glycogen synthase activity was 12% higher (P<0.05 but glycogen branching enzyme activity was 70% lower (P<0.01 in mdx compared with wild-type mice. The rate-limiting enzyme for glycogen breakdown, glycogen phosphorylase, had 62% lower activity (P<0.01 in mdx mice resulting from a 24% reduction in PKA activity (P<0.01. In mdx mice glycogen debranching enzyme expression was 50% higher (P<0.001 together with starch-binding domain protein 1 (219% higher; P<0.01. In addition, mdx mice were glucose intolerant (P<0.01 and had 30% less liver glycogen (P<0.05 compared with control mice. Subsequent analysis of the enzymes dysregulated in skeletal muscle glycogen metabolism in mdx mice identified reduced glycogenin protein expression (46% less; P<0.05 as a possible cause of this phenotype.We identified that mdx mice were glucose intolerant, and had increased skeletal muscle glycogen but reduced amounts of liver glycogen.

    Full Text Available Abstract Background Participation restriction is defined as "problems an individual may experience in involvement in life situations" and refers to the personal and societal consequences of health conditions. There is a growing interest in participation restriction because (i problems with work or looking after others may be more concerning to individuals than the signs and symptoms of health conditions and (ii even when poor health persists, participation may still be maintained. The natural history of participation restriction in the general population is unknown and the aim of this report is to describe change in status of person-perceived participation restriction over three years in community-dwelling adults aged 50 years and over. Method Prospective cohort study (baseline and 3-year follow-up using postal questionnaires mailed to a population-based sample of older adults. Responders were included in this study if they completed all items of the Keele Assessment of Participation at baseline (n = 6965. Estimates of onset and persistence of person-perceived participation restriction at 3-year follow-up were calculated for any and for each aspect of life in the sample as a whole, and then by age and gender using attrition re-weighted logistic regression to take account of sample attrition. Results In the whole sample of 6965 persons, overall participation status at three years was unchanged in 69%, and changed in 31%. Of 3431 persons with no restriction at baseline, it is estimated that 29.8% (95% confidence interval: 27.6%, 32.0% would report restriction in at least one aspect of life at 3-year follow-up. Of 3534 persons who had baseline restriction, it is estimated that 68.8% (66.2%, 71.3% would report continuing restriction in at least one aspect of life after 3 years. Onset and persistence both increased with age, and were most frequently recorded for restricted mobility outside the home. Conclusion Although most older persons do not

    Frequent feeds with carbohydrate-rich meals or continuous enteral feeding has been the therapy of choice in glycogen storage disease (Glycogenosis) type III. Recent guidelines on diagnosis and management recommend frequent feedings with high complex carbohydrates or cornstarch avoiding fasting in children, while in adults a low-carb-high-protein-diet is recommended. While this regimen can prevent hypoglycaemia in children it does not improve skeletal and heart muscle function, which are compromised in patients with glycogenosis IIIa. Administration of carbohydrates may elicit reactive hyperinsulinism, resulting in suppression of lipolysis, ketogenesis, gluconeogenesis, and activation of glycogen synthesis. Thus, heart and skeletal muscle are depleted of energy substrates. Modified Atkins diet leads to increased blood levels of ketone bodies and fatty acids. We hypothesize that this health care intervention improves the energetic balance of muscles. We treated 2 boys with glycogenosis IIIa aged 9 and 11 years with a modified Atkins diet (10 g carbohydrate per day, protein and fatty acids ad libitum) over a period of 32 and 26 months, respectively. In both patients, creatine kinase levels in blood dropped in response to Atkins diet. When diet was withdrawn in one of the patients he complained of chest pain, reduced physical strength and creatine kinase levels rapidly increased. This was reversed when Atkins diet was reintroduced. One patient suffered from severe cardiomyopathy which significantly improved under diet. Patients with glycogenosis IIIa benefit from an improved energetic state of heart and skeletal muscle by introduction of Atkins diet both on a biochemical and clinical level. Apart from transient hypoglycaemia no serious adverse effects were observed.

Specifically, reduced levels of these pools of glycogen are associated with reduced SR Ca(2+) release, muscle relaxation rate, and membrane excitability. Collectively, the available literature strongly demonstrates...... that the subcellular localization of glycogen has to be considered to fully understand the role of glycogen metabolism and signaling in skeletal muscle function.

  3. Maturity of judgement in decision making for predictive testing for nontreatable adult-onset neurogenetic conditions: a case against predictive testing of minors.

    2006-11-01

    International guidelines developed to minimize harm from predictive testing for adult-onset, nontreatable neurogenetic conditions such as Huntington disease (HD) state that such testing should not be available to minors. Some authors have proposed that predictive testing for these conditions should be available to minors at the request of parents and/or of younger adolescents themselves. They highlight the lack of empirical evidence that predictive testing of minors causes harm and suggest that refusing to test minors may be detrimental. The current study focuses on the context of predictive test requests by adolescents younger than 18 years, and presents arguments and evidence that the risk of potential harm from testing such young people is sufficiently high to justify continued caution in this area. A study based on a model of psychosocial maturity found that the 3 factors involved in maturity of judgement in decision making - responsibility, temperance and perspective - continue to develop into late adolescence. There is also evidence that the prefrontal areas of the brain, which are involved in executive functions such as decision making, are not fully developed until early adulthood. Combined with evidence of adverse long-term effects, from research with adults who have undergone predictive testing, these findings constitute grounds for retaining a minimum age of 18 years for predictive testing for nontreatable conditions. Further research on assessment of maturity will assist with reaching a consensus on this issue.

    Full Text Available Vertebrobasilar insufficiency leading to posterior circulation infarcts caused by congenital hypoplasia of the bilateral transverse foramina at the C2 level, affecting the caliber and flow of the bilateral distal cervical vertebral arteries in an adult, has not been previously reported. A 41-year-old male presented with episodic dizziness for a period of 1 year prior to consultation. Computed tomography angiography of the head and neck demonstrated congenital hypoplasia of the bilateral C2 transverse foramina, with absence of the vertebral arteries in each of the foramina and collateral reconstitution of diminutive intracranial vertebral artery segments. Brain MRI showed postinfarction encephalomalacia in the bilateral cerebellar hemispheres. The patient was considered not a surgical or endovascular candidate and was managed conservatively with antiplatelet therapy. Congenital anomalies of the bilateral cervical transverse foramina may present with vertebrobasilar insufficiency and infarction in adulthood.

  8. The modulation of the symbiont/host interaction between Wolbachia pipientis and Aedes fluviatilis embryos by glycogen metabolism.

    Directory of Open Access Journals (Sweden)

    Mariana da Rocha Fernandes

    Full Text Available Wolbachia pipientis, a maternally transmitted bacterium that colonizes arthropods, may affect the general aspects of insect physiology, particularly reproduction. Wolbachia is a natural endosymbiont of Aedes fluviatilis, whose effects in embryogenesis and reproduction have not been addressed so far. In this context, we investigated the correlation between glucose metabolism and morphological alterations during A. fluviatilis embryo development in Wolbachia-positive (W+ and Wolbachia-negative (W- mosquito strains. While both strains do not display significant morphological and larval hatching differences, larger differences were observed in hexokinase activity and glycogen contents during early and mid-stages of embryogenesis, respectively. To investigate if glycogen would be required for parasite-host interaction, we reduced Glycogen Synthase Kinase-3 (GSK-3 levels in adult females and their eggs by RNAi. GSK-3 knock-down leads to embryonic lethality, lower levels of glycogen and total protein and Wolbachia reduction. Therefore, our results suggest that the relationship between A. fluviatilis and Wolbachia may be modulated by glycogen metabolism.

    Control of energy metabolism is an essential process for life. In insects, egg formation (oogenesis) and embryogenesis is dependent on stored molecules deposited by the mother or transcribed later by the zygote. In oviparous insects the egg becomes an isolated system after egg laying with all energy conversion taking place during embryogenesis. Previous studies in a few vector species showed a strong correlation of key morphogenetic events and changes in glucose metabolism. Here, we investigate glycogen and glucose metabolism in the red flour beetle Tribolium castaneum, an insect amenable to functional genomic studies. To examine the role of the key enzymes on glycogen and glucose regulation we cloned and analyzed the function of glycogen synthase kinase 3 (GSK-3) and hexokinase (HexA) genes during T. castaneum embryogenesis. Expression analysis via in situ hybridization shows that both genes are expressed only in the embryonic tissue, suggesting that embryonic and extra-embryonic cells display different metabolic activities. dsRNA adult female injection (parental RNAi) of both genes lead a reduction in egg laying and to embryonic lethality. Morphological analysis via DAPI stainings indicates that early development is impaired in Tc-GSK-3 and Tc-HexA1 RNAi embryos. Importantly, glycogen levels are upregulated after Tc-GSK-3 RNAi and glucose levels are upregulated after Tc-HexA1 RNAi, indicating that both genes control metabolism during embryogenesis and oogenesis, respectively. Altogether our results show that T. castaneum embryogenesis depends on the proper control of glucose and glycogen. PMID:23750237

    Glycogen synthesis is a major component of the insulin response, and defective glycogen synthesis is a major portion of insulin resistance. Insulin regulates glycogen synthase (GS) through incompletely defined pathways that activate the enzyme through dephosphorylation and, more potently, allosteric activation. We identify Epm2aip1 as a GS-associated protein. We show that the absence of Epm2aip1 in mice impairs allosteric activation of GS by glucose 6-phosphate, decreases hepatic glycogen synthesis, increases liver fat, causes hepatic insulin resistance, and protects against age-related obesity. Our work identifies a novel GS-associated GS activity-modulating component of insulin resistance. PMID:24142699

    The objective of this study was to determine how increasing the hepatic glycogen content would affect the liver's ability to take up and metabolize glucose. During the first 4 h of the study, liver glycogen deposition was stimulated by intraportal fructose infusion in the presence of hyperglycemic-normoinsulinemia. This was followed by a 2-h hyperglycemic-normoinsulinemic control period, during which the fructose infusion was stopped, and a 2-h experimental period in which net hepatic glucose uptake (NHGU) and disposition (glycogen, lactate, and CO(2)) were measured in the absence of fructose but in the presence of a hyperglycemic-hyperinsulinemic challenge including portal vein glucose infusion. Fructose infusion increased net hepatic glycogen synthesis (0.7 ± 0.5 vs. 6.4 ± 0.4 mg/kg/min; P vs. 100 ± 3 mg/g; P fructose infusion group) did not alter NHGU, but it reduced the percent of NHGU directed to glycogen (79 ± 4 vs. 55 ± 6; P vs. 29 ± 5; P = 0.01) and oxidation (9 ± 3 vs. 16 ± 3; P = NS). This change was associated with increased AMP-activated protein kinase phosphorylation, diminished insulin signaling, and a shift in glycogenic enzyme activity toward a state discouraging glycogen accumulation. These data indicate that increases in hepatic glycogen can generate a state of hepatic insulin resistance, which is characterized by impaired glycogen synthesis despite preserved NHGU.

  13. Contributions of glycogen to astrocytic energetics during brain activation.

    Glycogen is the major store of glucose in brain and is mainly in astrocytes. Brain glycogen levels in unstimulated, carefully-handled rats are 10-12 μmol/g, and assuming that astrocytes account for half the brain mass, astrocytic glycogen content is twice as high. Glycogen turnover is slow under basal conditions, but it is mobilized during activation. There is no net increase in incorporation of label from glucose during activation, whereas label release from pre-labeled glycogen exceeds net glycogen consumption, which increases during stronger stimuli. Because glycogen level is restored by non-oxidative metabolism, astrocytes can influence the global ratio of oxygen to glucose utilization. Compensatory increases in utilization of blood glucose during inhibition of glycogen phosphorylase are large and approximate glycogenolysis rates during sensory stimulation. In contrast, glycogenolysis rates during hypoglycemia are low due to continued glucose delivery and oxidation of endogenous substrates; rates that preserve neuronal function in the absence of glucose are also low, probably due to metabolite oxidation. Modeling studies predict that glycogenolysis maintains a high level of glucose-6-phosphate in astrocytes to maintain feedback inhibition of hexokinase, thereby diverting glucose for use by neurons. The fate of glycogen carbon in vivo is not known, but lactate efflux from brain best accounts for the major metabolic characteristics during activation of living brain. Substantial shuttling coupled with oxidation of glycogen-derived lactate is inconsistent with available evidence. Glycogen has important roles in astrocytic energetics, including glucose sparing, control of extracellular K(+) level, oxidative stress management, and memory consolidation; it is a multi-functional compound.

    Despite an abundance of research on calorie restriction (CR) altering gonadal and appetite regulating hormones, the sexual behavioural consequences of CR remain to be examined systematically. This study compared the sexual behaviour, partner preference, serum testosterone and leptin levels of male adult Hooded Wistar rats administered a CR (continuous 25%, 50% CR or a temporary restriction) with ad libitum fed controls. The temporary restriction (Previous CR) failed to alter sexual behaviour, partner preference and levels of testosterone and leptin. The moderately 25% CR males did not demonstrate an impairment in sexual behaviour but did demonstrate a reduced level of attractiveness to females in one measure of partner preference. Sexual performance was affected by a substantial CR, as the CR 50% group exhibited a longer latency to the first intromission, indicating alteration in sexual arousal. Females also consistently demonstrated a clear preference for the control group compared to the CR 50% group. These findings indicate a possible reduction in the overall reproductive potential of the substantially CR animals. Testosterone levels were equally suppressed by both the 25% and 50% CR, while leptin levels were only reduced in the CR 50% group. Leptin, rather than testosterone, may have influenced the impairment in sexual behaviour only demonstrated by the substantially CR animals. Testosterone, may, however, play a role in modulating the preference of control over CR males, as attractiveness was totally reduced by a substantial CR, and partially reduced by a moderate restricted regimen.

    AIM: To investigate gene variants in a large Italian inflammatory bowel disease (IBD) cohort, and to analyze the correlation of sub-phenotypes (including age at diagnosis) and epistatic interaction with other IBD genes.METHODS: Total of 763 patients with Crohn's disease (CD, 189 diagnosed at age < 19 years),843 with ulcerative colitis (UC, 179 diagnosed <19 years), 749 healthy controls, and 546 healthy parents (273 trios) were included in the study. The rs2241880 [autophagy-related 16-like i (ATG16L1)],rs11209026 and rs7517847 [interleukin 23 receptor (IL23R)], rs2066844, rs2066845, rs2066847 (CARD15),rs1050152 (OCTN1), and rs2631367 (OCTN2) gene variants were genotyped.RESULTS: The frequency of G allele of ATG16L1 SNP (Ala197Thr) was increased in patients with CD compared with controls (59% vs 54% respectively)(OR = 1.25, CI = 1.08-1.45, P = 0.003), but not in UC (55%). The frequency of A and G (minor) alleles of Arg381GIn, rs11209026 and rs7517847 variants of IL23R were reduced significantly in CD (4%, OR =0.62, CI = 0.45-0.87, P = 0.005; 28%, OR = 0.64, CI= 0.55-0.75, P < 0.01), compared with controls (6%and 38%, respectively). The A allele (but not G) wasalso reduced significantly in UC (4%, OR = 0.69, CI =0.5-0.94, P = 0.019). No association was demonstrated with sub-phenotypes and interaction with CARD15,and OCTN1/2 genes, although both gene variants were associated with pediatric-onset disease.CONCLUSION: The present study confirms the association of IL23R polymorphisms with IBD, and ATG16L1 with CD, in both adult- and pediatric-onset subsets in our study population.

    To determine the relationship between pineal melatonin production and its appearance in circulation, the rising phase of the pineal and serum melatonin rhythm was studied in the adult Siberian hamster. Melatonin concentrations increased in the pineal gland and in serum at 1.50 and 1.75 h, respectively, relative to lights off in long days (16 h of light/day) and at 2.00 and 2.75 h, respectively, in short days (10 h of light/day). Thus, a photoperiod-dependent melatonin rise in circulation lagged production by the pineal gland by 0.50 h--a delay of 0.75 h in short-day hamsters versus 0.25 h in long-day hamsters. Following initiation of this rise, concentrations that were typical of the nighttime peak were achieved within 2 h of melatonin rhythm onset, regardless of photoperiod. To determine whether clock control of the rising phase of the melatonin rhythm, in the absence of photoperiod cues, may be disrupted by perturbations in the ambient magnetic field, hamsters in constant darkness were acutely exposed to a 1-Gauss, 60-Hz magnetic field for 15 min or were daily exposed to this treatment for 14 or 21 days. Neither the melatonin rise in pineal content or circulation during subjective night was affected by acute or chronic magnetic field exposures; testes regression similarly occurred in sham and daily magnetic field-exposed hamsters in constant darkness. These findings indicate that magnetic field exposures are unlikely to serve as a zeitgeber for the circadian mechanism that controls onset of the melatonin rhythm; rather, photoperiod is a predominant cue that may differentially regulate the rising phase of melatonin production in the pineal gland and concentration in circulation.

    An increase in narcolepsy incidence was noted after the novel pandemic influenza of 2009, leading to further interest in risk factors associated with this disease. However, there is limited data on the epidemiology of narcolepsy, particularly in the adult population. Therefore, we sought to examine narcolepsy incidence rates in the United States and describe associated characteristics. We performed a population based epidemiologic study of active duty military personnel. All outpatient clinics in the continental United States providing care for active duty military between 2004 through 2013 were included utilizing existing databases. Narcolepsy was defined in 3 ways: (1) 2 diagnoses of narcolepsy within 6months of each other, one made by a sleep expert; (2) 2 diagnoses by any provider followed by a narcolepsy prescription within 14days of last visit; and (3) procedure code for a sleep study followed by a narcolepsy diagnosis by a sleep expert within 6months. There were 1675 narcolepsy cases. Overall incidence of narcolepsy trended from 14.6 to 27.3 cases per 100,000 person-years, with an increase starting after 2005-2006 and peaking during the 2011-2012 influenza season. Higher frequencies were seen among females, non-Hispanic blacks, and members living in the south. Narcolepsy incidence rates among active duty military members are higher than previously described. The reason for the steady rise of incidence from 2005 to 2006 through 2011-2012 is unknown; however, these findings require further exploration. We detected risk factors associated with the development of narcolepsy which may aid in future study efforts. Published by Elsevier B.V.

    Disparities in epilepsy treatment are not uncommon; therefore, we examined population-based estimates of initial antiepileptic drugs (AEDs) in new-onset epilepsy among racial/ethnic minority groups of older US Medicare beneficiaries. We conducted retrospective analyses of 2008-2010 Medicare administrative claims for a 5% random sample of beneficiaries augmented for minority representation. New-onset epilepsy cases in 2009 had ≥1 International Classification of Diseases, Ninth Revision (ICD-9) 345.x or ≥2 ICD-9 780.3x, and ≥1 AED, AND no seizure/epilepsy claim codes or AEDs in preceding 365 days. We examined AED use and concordance with Quality Indicators of Epilepsy Treatment (QUIET) 6 (monotherapy as initial treatment = ≥30 day first prescription with no other concomitant AEDs), and prompt AED treatment (first AED within 30 days of diagnosis). Logistic regression examined likelihood of prompt treatment by demographic (race/ethnicity, gender, age), clinical (number of comorbid conditions, neurology care, index event occurring in the emergency room (ER)), and economic (Part D coverage phase, eligibility for Part D Low Income Subsidy [LIS], and ZIP code level poverty) factors. Over 1 year of follow-up, 79.6% of 3,706 new epilepsy cases had one AED only (77.89% of whites vs. 89% of American Indian/Alaska Native [AI/AN]). Levetiracetam was the most commonly prescribed AED (45.5%: from 24.6% AI/AN to 55.0% whites). The second most common was phenytoin (30.6%: from 18.8% Asians to 43.1% AI/AN). QUIET 6 concordance was 94.7% (93.9% for whites to 97.3% of AI/AN). Only 50% received prompt AED therapy (49.6% whites to 53.9% AI/AN). Race/ethnicity was not significantly associated with AED patterns, monotherapy use, or prompt treatment. Monotherapy is common across all racial/ethnic groups of older adults with new-onset epilepsy, older AEDs are commonly prescribed, and treatment is frequently delayed. Further studies on reasons for treatment delays are warranted

    To understand how glycogen affects skeletal muscle physiology, we examined enzymes essential for muscle glycogen synthesis and degradation using single fibers from quiescent and stimulated rat skeletal muscle. Presenting a shift in paradigm, we show these proteins are differentially associated with glycogen granules. Protein diffusibility and/or abundance of glycogenin, glycogen branching enzyme (GBE), debranching enzyme (GDE), phosphorylase (GP), and synthase (GS) were examined in fibers isolated from rat fast-twitch extensor digitorum longus (EDL) and slow-twitch soleus (SOL) muscle. GDE and GP proteins were more abundant (~10- to 100-fold) in fibers from EDL compared with SOL muscle. GS and glycogenin proteins were similar between muscles while GBE had an approximately fourfold greater abundance in SOL muscle. Mechanically skinned fibers exposed to physiological buffer for 10 min showed ~70% total pools of GBE and GP were diffusible (nonbound), whereas GDE and GS were considerably less diffusible. Intense in vitro stimulation, sufficient to elicit a ~50% decrease in intracellular glycogen, increased diffusibility of GDE, GP, and GS (~15-60%) and decreased GBE diffusibility (~20%). Amylase treatment, which breaks α-1,4 linkages of glycogen, indicated differential diffusibilities and hence glycogen associations of GDE and GS. Membrane solubilization (1% Triton-X-100) allowed a small additional amount of GDE and GS to diffuse from fibers, suggesting the majority of nonglycogen-associated GDE/GS is associated with myofibrillar/contractile network of muscle rather than membranes. Given differences in enzymes required for glycogen metabolism, the current findings suggest glycogen particles have fiber-type-dependent structures. The greater catabolic potential of glycogen breakdown in fast-twitch fibers may account for different contraction induced rates of glycogen utilization.

    Adult-onset sporadic ataxias are a group of disorders manifested predominantly with ataxia, due to a variety of the potential causes including intoxication, immune-mediation, vitamins deifciencies, infections, neurodegeneration, and even some hereditary conditions. The clinical spectrum of these disorders is diverse, and their diagnosis remains a challenge. Compared with hereditary ataxias, most ataxias in this group respond the treatment well, that means the signiifcance of timely and correct diagnosis. The advanced biochemical, immune and imaging tools will help the perception and management on those ataxias. Different categories of adult-onset sporadic ataxia were elucidated with the highlight on their clinical features, neuro-imagingand diagnostic criteria.%成人发病的散发性共济失调症是由多种原因所致,临床表现以共济失调为主要的多种疾病。致病原因包括中毒、免疫介导性、维生素缺乏、感染性疾病、变性病以及遗传性疾患等。散发性共济失调临床谱具有明显异质性,临床正确诊断极具挑战性。但相比于遗传性共济失调症,此类疾患多数治疗效果较好,及时、正确诊断尤为重要。现代生化、免疫以及影像学技术有助于此类疾患的认识和诊治。文中综述并讨论可致成人发病的散发性共济失调的不同疾病分类,并着重其临床和神经影像学表现及诊断标准。

    Previously, myelin from cerebral white matter (CWM) of two subjects of a family with orthochromatic adult-onset autosomal-dominant leukodystrophy (ADLD) was disclosed to exhibit defective large isoform of myelin-associated glycoprotein (L-MAG) and patchy distribution only in the elder subject. L-MAG and neural cell adhesion molecule (N-CAM) (N-CAM 180, 140, and 120) are structurally related and concur to myelin/axon interaction. In early developmental stages, in neurons and glia N-CAM is converted into polysialylated (PSA)-NCAM by two sialyltransferases sialyltransferase-X (STX) and polysialyltransferase-1 (PST). Notably, PSA-NCAM disrupts N-CAM adhesive properties and is nearly absent in the adult brain. Here, CWM extracts and myelin of the two subjects were searched for the expression pattern of the N-CAM isoforms and PSA-NCAM, and their CWM was evaluated for N-CAM, STX and PST gene copy number and gene expression as mRNA. Biochemically, we disclosed that in CWM extracts and myelin from both subjects, PSA-NCAM accumulates, N-CAM 180 considerably increases, N-CAM 140 is modestly modified and N-CAM 120 remarkably decreases; duplication of genes encoding N-CAM, STX and PST was not revealed, whereas PST mRNA was clearly increased. Immunohistochemically, in CWM of both subjects, we found an unusually diffuse accumulation of PSA-NCAM without inflammation markers. PSA-NCAM persistence, up-regulated PST mRNA and previously uncovered defective L-MAG may be early pathogenetic events in this ADLD form.

Multiple linear and logistic regression models were used to analyze the association between eating disorder and depressive symptoms and their associations with HbA1c.A total of 30.2% of the women and 9.5% of the men were screening positive for eating disorders. The mean PHQ-9 score (standard deviation was 5.3 (4.4 among women and 3.9 (3.6 among men. Screening positive for an eating disorder was associated with more severe depressive symptoms among women (βwomen 3.8, p<0.001. However, neither eating disorder symptoms nor severity of depressive symptoms were associated with HbA1c among women, while HbA1c increased with the severity of depressive symptoms among men (βmen 0.14, p=0.006.Because of the high prevalence of eating disorder and depressive symptoms, their interrelationship, and their associations with metabolic control, particularly among men, regular mental health screening is recommended for young adults with type 1 diabetes.

We performed a retrospective analysis of patients with AOSD with fever who were admitted to Severance Hospital between 2005 and 2016. The patients with AOSD were evaluated for MAS using the 2016 classification criteria for MAS. Clinical features, laboratory findings, and overall survival were analyzed. Logistic regression analysis was used to evaluate the factors associated with in-hospital mortality. Among 64 patients with AOSD, 36 (56.3%) were classified as having MAS. The overall survival rate was significantly lower in patients with MAS than in those without (67% vs 100%, p EULAR/ACR/PRINTO classification criteria for MAS are potentially useful for the identification of patients with AOSD at high risk for a poor outcome. Febrile patients with AOSD should be monitored with the 2016 classification criteria for MAS in the early diagnosis and proper treatment of MAS.

    Transactivating response region DNA binding protein (TDP-43) is the major protein component of ubiquitinated inclusions found in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) with ubiquitinated inclusions. Two ALS-causing mutants (TDP-43(Q331K) and TDP-43(M337V)), but not wild-type human TDP-43, are shown here to provoke age-dependent, mutant-dependent, progressive motor axon degeneration and motor neuron death when expressed in mice at levels and in a cell type-selective pattern similar to endogenous TDP-43. Mutant TDP-43-dependent degeneration of lower motor neurons occurs without: (i) loss of TDP-43 from the corresponding nuclei, (ii) accumulation of TDP-43 aggregates, and (iii) accumulation of insoluble TDP-43. Computational analysis using splicing-sensitive microarrays demonstrates alterations of endogenous TDP-43-dependent alternative splicing events conferred by both human wild-type and mutant TDP-43(Q331K), but with high levels of mutant TDP-43 preferentially enhancing exon exclusion of some target pre-mRNAs affecting genes involved in neurological transmission and function. Comparison with splicing alterations following TDP-43 depletion demonstrates that TDP-43(Q331K) enhances normal TDP-43 splicing function for some RNA targets but loss-of-function for others. Thus, adult-onset motor neuron disease does not require aggregation or loss of nuclear TDP-43, with ALS-linked mutants producing loss and gain of splicing function of selected RNA targets at an early disease stage.

  10. Iron Deficiency Anemia in Adult Onset Still's Disease with a Serum Ferritin of 26,387 μg/L

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Serum ferritin rises in the anemia of chronic inflammation reflecting increased iron storage and other changes mediated by inflammation. When iron deficiency coexists, the ferritin may not always decline into the subnormal range. We describe the rare interaction of iron deficiency with the extreme hyperferritinemia characteristic of adult onset Still's disease. The combination has clinical relevance and allows deductions about the presence of serum ferritin at 26,387 μg/L despite obvious iron depletion. The diagnosis of iron deficiency anemia was delayed and became fully obvious when her Still's disease remitted and serum ferritin decreased to 6.5 μg/L. The coexistence of iron deficiency should be considered when evaluating a patient with anemia of chronic inflammation even when the ferritin level is elevated several hundredfold. Further insights on ferritin metabolism in Still's disease are suggested by the likelihood that the patient's massive hyperferritinemia in the acute phase of Still's disease was almost entirely of the iron-free apoferritin form.

    Human T-cell lymphotropic virus type 1 (HTLV-1) is endemic in some regions and its vertical transmission occurs mainly through breastfeeding. About 10% of carriers develop associated diseases including HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP), adult T-cell leukemia/lymphoma (ATL) and infectious dermatitis associated with HTLV-1 (IDH). We searched for available case reports of early-onset HAM/TSP and ATL to evaluate demographic and disease aspects in infantile-juvenile patients. In the reviewed literature, 27 HAM/TSP and 31 ATL cases were found. In almost all of them, the most likely route of transmission was through breastfeeding. ATL is rarely reported, notwithstanding it may be underestimated because T-cell lymphomas are not investigated for HTLV-1 infection in this age group. IDH was frequently associated with HAM/TSP. The investigation of HTLV-1 infection in pregnant women is an important matter of public health and should be mandatory in endemic countries. © The Author [2017].

    This study examined the feasibility of providing motivational interviewing (MI) training to parents of young adults with recent-onset schizophrenia and co-occurring cannabis use. The training was offered in a mental health care setting as part of a family motivational intervention (FMI). Ninety-seven parents were randomly assigned to either FMI or routine family support (RFS). To obtain a measure of parent's MI skills at baseline and 3 months after they completed FMI, their role-play interactions with an actor portraying their child were coded. The coding method had satisfactory inter-rater reliability and internal consistency. At follow-up, parents in FMI showed significantly greater adherence to (p=.03) and competence in (p=.04) MI than parents in RFS. Parents in FMI also demonstrated significantly greater increases in expressing empathy (p=.01). These results demonstrate that FMI is a feasible method for increasing MI skills in parents. Additional research is needed to better understand the unique application of MI to parent-child interactions.

    Trichomonas vaginalis, a parasitic protist, is the causative agent of the common sexually-transmitted infection trichomoniasis. The organism has long been known to synthesize substantial glycogen as a storage polysaccharide, presumably mobilizing this compound during periods of carbohydrate limitation, such as might be encountered during transmission between hosts. However, little is known regarding the enzymes of glycogen metabolism in T. vaginalis. We had previously described the identification and characterization of two forms of glycogen phosphorylase in the organism. Here, we measure UDP-glucose-dependent glycogen synthase activity in cell-free extracts of T. vaginalis. We then demonstrate that the TVAG_258220 open reading frame encodes a glycosyltransferase that is presumably responsible for this synthetic activity. We show that expression of TVAG_258220 in a yeast strain lacking endogenous glycogen synthase activity is sufficient to restore glycogen accumulation. Furthermore, when TVAG_258220 is expressed in bacteria, the resulting recombinant protein has glycogen synthase activity in vitro, transferring glucose from either UDP-glucose or ADP-glucose to glycogen and using both substrates with similar affinity. This protein is also able to transfer glucose from UDP-glucose or ADP-glucose to maltose and longer oligomers of glucose but not to glucose itself. However, with these substrates, there is no evidence of processivity and sugar transfer is limited to between one and three glucose residues. Taken together with our earlier work on glycogen phosphorylase, we are now well positioned to define both how T. vaginalis synthesizes and utilizes glycogen, and how these processes are regulated.

    Recent studies have demonstrated that growth hormone (GH)-deficient adults have a markedly decreased bone mineral content compared to healthy adults. However, there are conflicting results regarding the effects of GH treatment on bone mineral content in GH-deficient adults. Therefore, we evaluated...... the effect of GH treatment on a marker of bone formation (bone alkaline phosphatase), hepatic excretory function and distal forearm bone mineral content in GH-deficient adults. Growth hormone was administered subcutaneously in 21 adults (13 males and 8 females) with GH deficiency of childhood onset for 4...... months in a double-blind, placebo-controlled GH trial, while 13 of the patients then received further GH for an additional 14 months. Serum insulin-like growth factor I (IGF-I) increased significantly from 100 to 279 micrograms/l and IGF binding protein-3 (IGFBP-3) from 1930 to 3355 micrograms/l after 4...

  15. Glycogen metabolism and the homeostatic regulation of sleep

    KAUST Repository

    Petit, Jean-Marie

    2014-11-16

    In 1995 Benington and Heller formulated an energy hypothesis of sleep centered on a key role of glycogen. It was postulated that a major function of sleep is to replenish glycogen stores in the brain that have been depleted during wakefulness which is associated to an increased energy demand. Astrocytic glycogen depletion participates to an increase of extracellular adenosine release which influences sleep homeostasis. Here, we will review some evidence obtained by studies addressing the question of a key role played by glycogen metabolism in sleep regulation as proposed by this hypothesis or by an alternative hypothesis named “glycogenetic” hypothesis as well as the importance of the confounding effect of glucocorticoïds. Even though actual collected data argue in favor of a role of sleep in brain energy balance-homeostasis, they do not support a critical and direct involvement of glycogen metabolism on sleep regulation. For instance, glycogen levels during the sleep-wake cycle are driven by different physiological signals and therefore appear more as a marker-integrator of brain energy status than a direct regulator of sleep homeostasis. In support of this we provide evidence that blockade of glycogen mobilization does not induce more sleep episodes during the active period while locomotor activity is reduced. These observations do not invalidate the energy hypothesis of sleep but indicate that underlying cellular mechanisms are more complex than postulated by Benington and Heller.

    Full Text Available Background: Interleukin (IL-1 plays a crucial role in the pathogenesis of Adult onset Still’s disease (AOSD.Objectives: To evaluate the efficacy and safety of anakinra (ANA and canakinumab (CAN in a large group of AOSD patients.Methods: Data on clinical, serological features, and concomitant treatments were retrospectively collected at baseline and after 3, 6, and 12 months from AOSD patients (Yamaguchi criteria referred by 18 Italian centers. Pouchot’s score was used to evaluate disease severity.Results: One hundred forty patients were treated with ANA; 4 were subsequently switched to CAN after ANA failure. The systemic pattern of AOSD was identified in 104 (74.2% of the ANA-treated and in 3 (75% of the CAN-treated groups; the chronic-articular type of AOSD was identified in 48 (25.8% of the ANA-treated and in 1 (25% of the CAN-treated groups. Methotrexate (MTX was the most frequent disease modifying anti-rheumatic drug (DMARD used before beginning ANA or CAN [91/140 (75.8%, 2/4 (50%, respectively]. As a second-line biologic DMARD therapy in 29/140 (20.7% of the patients, ANA was found effective in improving all clinical and serological manifestations (p < 0.0001, and Pouchot’s score was found to be significantly reduced at all time points (p < 0.0001. No differences in treatment response were identified in the ANA-group when the patients were stratified according to age, sex, disease pattern or mono/combination therapy profile. ANA primary and secondary inefficacy at the 12-month time point was 15/140 (10.7% and 11/140 (7.8%, respectively. Adverse events (AEs [mainly represented by in situ (28/47, 59.5% or diffuse (12/47, 25.5% skin reactions and infections (7/47, 14.8%] were the main causes for discontinuation. Pouchot’s score and clinical and serological features were significantly ameliorated at all time points (p < 0.0001 in the CAN-group, and no AEs were registered during CAN therapy. Treatment was suspended for loss of efficacy

    New-onset refractory status epilepticus (NORSE) is defined as a sudden onset of refractory status epilepticus in patients who do not have a history of epilepsy. It is a neurologic emergency, and determining the underlying etiology is an important factor for effectively managing and predicting the prognosis of NORSE. We describe the case of a 28-year-old woman who was hospitalized with NORSE secondary to an unknown etiology. She did not respond to traditional anticonvulsant therapy, including benzodiazepines, fosphenytoin, propofol, and levetiracetam. The patient was placed on continuous electroencephalography (EEG) monitoring and was treated further with multiple antiepileptics, which were titrated aggressively based on EEG readings and therapeutic drug levels; despite this treatment, EEG monitoring revealed continued seizures. Thus, high-dose corticosteroids were started for seizure control. Her workup included computed tomography and magnetic resonance imaging of the head, a lumbar puncture, toxicology screening, and extensive testing for multiple infectious and inflammatory etiologies. The patient's history revealed recent exposure to a new cat. Serologic results were positive for Bartonella henselae, and she was diagnosed with cat-scratch disease (CSD). She did not have the typical presentation of symptoms of lymphadenopathy, however, which is common in CSD. Doxycycline 100 mg and rifampin 300 mg twice daily were added to the patient's anticonvulsant and corticosteroid therapy. She was hospitalized for a total of 26 days and discharged with only minor neurologic impairment (short-term memory deficits and minor cognitive problems). The patient was discharged receiving antiepileptics, antibiotics, and a corticosteroid taper. To our knowledge, this is the first clinically known case of NORSE secondary to CSD without typical CSD symptoms in the adult population. The patient failed to respond to traditional anticonvulsant therapy alone. With the addition of high

We aimed to examine whether regular ICS use was associated with a reduced risk for future malignancy in patients with newly diagnosed adult-onset asthma. Methods: We used a population-based cohort study between 2001 and 2008 with appropriate person-time analysis. Participants were followed up until the first incident of cancer, death, or to the end of 2008. The Cox model was used to derive an adjusted hazard ratio (aHR for cancer development. Kaplan–Meier cancer-free survival curves of two groups were compared. Results: The exposed group of 2,117 regular ICS users and the nonexposed group of 17,732 non-ICS users were assembled. After 7,365 (mean, 3.5 years; standard deviation 2.1 and 73,789 (mean, 4.1 years; standard deviation 2.4 person-years of follow-up for the ICS users and the comparator group of non-ICS users, respectively, the aHR for overall cancer was nonsignificantly elevated at 1.33 with 95% confidence interval (CI, 1.00–1.76, P=0.0501.

    Full Text Available The glaucomas comprise a genetically complex group of retinal neuropathies that typically occur late in life and are characterized by progressive pathology of the optic nerve head and degeneration of retinal ganglion cells. In addition to age and family history, other significant risk factors for glaucoma include elevated intraocular pressure (IOP and myopia. The complexity of glaucoma has made it difficult to model in animals, but also challenging to identify responsible genes. We have used zebrafish to identify a genetically complex, recessive mutant that shows risk factors for glaucoma including adult onset severe myopia, elevated IOP, and progressive retinal ganglion cell pathology. Positional cloning and analysis of a non-complementing allele indicated that non-sense mutations in low density lipoprotein receptor-related protein 2 (lrp2 underlie the mutant phenotype. Lrp2, previously named Megalin, functions as an endocytic receptor for a wide-variety of bioactive molecules including Sonic hedgehog, bone morphogenic protein 4, retinol-binding protein, vitamin D-binding protein, and apolipoprotein E, among others. Detailed phenotype analyses indicated that as lrp2 mutant fish age, many individuals--but not all--develop high IOP and severe myopia with obviously enlarged eye globes. This results in retinal stretch and prolonged stress to retinal ganglion cells, which ultimately show signs of pathogenesis. Our studies implicate altered Lrp2-mediated homeostasis as important for myopia and other risk factors for glaucoma in humans and establish a new genetic model for further study of phenotypes associated with this disease.

    Full Text Available S100A8/A9 has been suggested as a marker of disease activity in patients with adult-onset Still’s disease (AOSD. We evaluated the clinical significance of S100A8/A9 as a biomarker and its pathogenic role in AOSD. Blood samples were collected prospectively from 20 AOSD patients and 20 healthy controls (HCs. Furthermore, skin and lymph node biopsy specimens of AOSD patients were investigated for S100A8/A9 expression levels via immunohistochemistry. Peripheral blood mononuclear cells (PBMCs of active AOSD patients and HCs were investigated for S100A8/A9 cell signals. S100A8/A9, interleukin-1β (IL-1β, and tumor necrosis factor-α (TNF-α levels in active AOSD patients were higher than those of HCs. S100A8/A9 levels correlated positively with IL-1β, TNF-α and C-reactive protein. The inflammatory cells expressing S100A8/A9 were graded from one to three in skin and lymph node biopsies of AOSD patients. The grading for S100A8/A9 was more intense in the skin lesions with karyorrhexis, mucin deposition, and neutrophil infiltration. Like lipopolysaccharide (LPS, S100A8/A9 induced phosphorylation of p38 and c-Jun amino-terminal kinase (JNK in PBMCs, suggesting that S100A8/A9 activates Toll-like receptor 4 signaling pathways. These findings suggest that S100A8/A9 may be involved in the inflammatory response with induction of proinflammatory cytokines and may serve as a clinicopathological marker for disease activity in AOSD.

    Transactivating response region DNA binding protein (TDP-43) is the major protein component of ubiquitinated inclusions found in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) with ubiquitinated inclusions. Two ALS-causing mutants (TDP-43Q331K and TDP-43M337V), but not wild-type human TDP-43, are shown here to provoke age-dependent, mutant-dependent, progressive motor axon degeneration and motor neuron death when expressed in mice at levels and in a cell type-selective pattern similar to endogenous TDP-43. Mutant TDP-43-dependent degeneration of lower motor neurons occurs without: (i) loss of TDP-43 from the corresponding nuclei, (ii) accumulation of TDP-43 aggregates, and (iii) accumulation of insoluble TDP-43. Computational analysis using splicing-sensitive microarrays demonstrates alterations of endogenous TDP-43–dependent alternative splicing events conferred by both human wild-type and mutant TDP-43Q331K, but with high levels of mutant TDP-43 preferentially enhancing exon exclusion of some target pre-mRNAs affecting genes involved in neurological transmission and function. Comparison with splicing alterations following TDP-43 depletion demonstrates that TDP-43Q331K enhances normal TDP-43 splicing function for some RNA targets but loss-of-function for others. Thus, adult-onset motor neuron disease does not require aggregation or loss of nuclear TDP-43, with ALS-linked mutants producing loss and gain of splicing function of selected RNA targets at an early disease stage.

    Full Text Available Abstract Background Most patients with growth hormone deficiency (GHD show high body mass index. Overweight subjects, but GHD patients, were demonstrated to have high left ventricular mass index (LVMi and abnormal LV geometric remodeling. We sought to study these characteristics in a group of GHD patients, in an attempt to establish the BMI-independent role of GHD. Methods Fifty-four patients, 28 F and 26 M, aged 45.9 ± 13.1, with adult-onset GHD (pituitary adenomas 48.2%, empty sella 27.8%, pituitary inflammation 5.5%, cranio-pharyngioma 3.7%, not identified pathogenesis 14.8% were enrolled. To minimize any possible interferences of BMI on the aim of this study, the control group included 20 age- and weight-matched healthy subjects. The LV geometry was identified by the relationship between LVMi (cut-off 125 g/m2 and relative wall thickness (cut-off 0.45 at echocardiography. Results There was no significant between-group difference in resting cardiac morphology and function, nor when considering age-related discrepancy. The majority of patients had normal-low LVM/LVMi, but about one fourth of them showed higher values. These findings correlated to relatively high circulating IGF-1 and systolic blood pressure at rest. The main LV geometric pattern was eccentric hypertrophy in 22% of GHD population (26% of with severe GHD and in 15% of controls (p = NS. Conclusion Though the lack of significant differences in resting LV morphology and function, about 25% of GHD patients showed high LVMi (consisting of eccentric hypertrophy, not dissimilarly to overweight controls. This finding, which prognostic role is well known in obese and hypertensive patients, is worthy to be investigated in GHD patients through wider controlled trials.

    Past cross-sectional studies have suggested that young adults with insulin-dependent (Type 1) diabetes mellitus (IDDM) may experience problems in their close peer relationships. For 10 years, we have followed an onset cohort of children and adolescents with IDDM (n = 57) and an age-matched group who were originally recruited after an acute illness, accident, or injury (n = 54). Now aged 19-26 years, these two groups were compared in terms of their friendship patterns, dating and love experiences, and sense of loneliness. All subjects in both groups had at least one friend. However, the IDDM group reported fewer friendships overall. The difference was accounted for by the number of less intimate friends. The two groups had similar frequencies of current romantic partners (IDDM = 63%; comparison group = 64%). While dating attitude and dating assertiveness did not differ between groups, some differences were found in terms of experiences of a primary love relationship. IDDM patients experienced less trust and sense of intimate friendship in these love relationships. No differences in loneliness were found. The preponderance of our findings indicate that the two groups had similar patterns and experiences of close peer relationships. Thus, the study does not suggest that IDDM leads to serious problems in forming social relationships for these patients during the transition to young adulthood. On the other hand, the IDDM patients' lower level of trust and intimacy within love relationships are consistent with other findings from this study suggesting specific areas of lowered self-worth that appear in social relationships.

    The brains of 10 Japanese patients with adult onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) encompassing hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) and pigmentary orthochromatic leukodystrophy (POLD) and eight Japanese patients with Nasu-Hakola disease (N-HD) and five age-matched Japanese controls were examined neuropathologically with special reference to lesion staging and dynamic changes of microglial subsets. In both diseases, the pathognomonic neuropathological features included spherically swollen axons (spheroids and globules), axon loss and changes of microglia in the white matter. In ALSP, four lesion stages based on the degree of axon loss were discernible: Stage I, patchy axon loss in the cerebral white matter without atrophy; Stage II, large patchy areas of axon loss with slight atrophy of the cerebral white matter and slight dilatation of the lateral ventricles; Stage III, extensive axon loss in the cerebral white matter and dilatation of the lateral and third ventricles without remarkable axon loss in the brainstem and cerebellum; Stage IV, devastated cerebral white matter with marked dilatation of the ventricles and axon loss in the brainstem and/or cerebellum. Internal capsule and pontine base were relatively well preserved in the N-HD, even at Stage IV, and the swollen axons were larger with a higher density in the ALSP. Microglial cells immunopositive for CD68, CD163 or CD204 were far more obvious in ALSP, than in N-HD, and the shape and density of the cells changed in each stage. With progression of the stage, clinical symptoms became worse to apathetic state, and epilepsy was frequently observed in patients at Stages III and IV in both diseases. From these findings, it is concluded that (i) shape, density and subsets of microglia change dynamically along the passage of stages and (ii) increase of IBA-1-, CD68-, CD163- and CD204-immunopositive cells precedes loss of axons in ALSP. © 2016

    Sensitisation to peach lipid transfer protein (LTP; Pru p 3) is significantly associated with severe allergic symptoms in adults, but little is known about the age at onset of peach allergy. We investigated a possible correlation between specific IgE levels to Pru p 3 and the age at onset of peach allergy. One hundred and forty-eight patients allergic to peach were divided into 6 classes according to the age at onset. Sera were analyzed for IgE antibodies to peach, rPru p 3, rPru p 1, rPru p 4, rBet v 1, rBet v 2, total IgE titre, and tryptase; all collected data were statistically analysed. A significant inverse correlation was found between the age at onset of peach allergy and anti-rPru p 3 IgE levels at diagnosis (p age at onset was directly correlated with both anti-rPru p 1 IgE levels (p = 0.0001; Spearman's ρ = 0.3197) and anti-rBet v 1 IgE levels (p = 0.0006; Spearman's ρ = 0.2914) at diagnosis. No correlations were detected between the reported age at onset and anti-peach, anti-rPru p 4, anti-rBet v 2 IgE and total IgE values and serum tryptase levels. At diagnosis, when peach allergy starts at a younger age, it is likely associated with Pru p 3 sensitisation, and the younger the onset, the higher the IgE titres. When peach allergy starts at an older age, it is more likely the result of cross-reactivity to Bet v1.

    clinical manifestations at disease onset and during follow-up of patients with Adult-Onset Still Disease (AOSD in a tertiary university hospital in Brazil. METHODS: Thirteen cases of AOSD were identified in the Arthritis Outpatients Unit - Unicamp. Their clinical records were reviewed retrospectively in order to determine clinical manifestations regarding disease onset, follow-up and prescription. RESULTS: The prevalence of AOSD was 4.3%. The mean age of disease onset was 30.8 years old with a slight prevalence of men (54.2%. Constitutional symptoms, fever and cutaneous rash were observed in all cases. Hepatic involvement was observed in 11 patients, splenomegaly in 4, hematuria in 4, cardiac involvement in 2 and pleuritis in 2. Poliarticular involvement was observed more frequently, and 50% of them presented carpal ankylosis after 3 years of follow-up. Ferritine was elevated in 9 of 13 patients during active disease. All patients used oral non-steroidal anti-inflammatory drugs, steroids and 7 patients needed methotrexate. CONCLUSIONS: Although AOSD is a rare multisystemic rheumatic disorder, it should always be considered in febrile cases with poliarthritis. Neoplasia and infection should always be excluded. Normally it is characterized by a chronic course and carpal ankylosis as the main disabling feature.

  13. Acid hydrolysis and molecular density of phytoglycogen and liver glycogen helps understand the bonding in glycogen α (composite particles.

    Full Text Available Phytoglycogen (from certain mutant plants and animal glycogen are highly branched glucose polymers with similarities in structural features and molecular size range. Both appear to form composite α particles from smaller β particles. The molecular size distribution of liver glycogen is bimodal, with distinct α and β components, while that of phytoglycogen is monomodal. This study aims to enhance our understanding of the nature of the link between liver-glycogen β particles resulting in the formation of large α particles. It examines the time evolution of the size distribution of these molecules during acid hydrolysis, and the size dependence of the molecular density of both glucans. The monomodal distribution of phytoglycogen decreases uniformly in time with hydrolysis, while with glycogen, the large particles degrade significantly more quickly. The size dependence of the molecular density shows qualitatively different shapes for these two types of molecules. The data, combined with a quantitative model for the evolution of the distribution during degradation, suggest that the bonding between β into α particles is different between phytoglycogen and liver glycogen, with the formation of a glycosidic linkage for phytoglycogen and a covalent or strong non-covalent linkage, most probably involving a protein, for glycogen as most likely. This finding is of importance for diabetes, where α-particle structure is impaired.

    It has been debated in the literature whether patients with idiopathic generalized epilepsy (IGE) have a distinctive, evening-oriented chronotype. The few questionnaire-based studies that are available in the literature have conflicting results. The aim of our study was to define chronotype in patients with IGE by determining dim light melatonin onset (DLMO). Twenty adults diagnosed with IGE (grand mal on awakening [GM] in 7 cases and juvenile myoclonic epilepsy in 13 cases) were investigated by means of a face-to-face semistructured sleep interview, Morningness-Eveningness Questionnaire (MEQ), Pittsburgh Sleep Quality Index (PSQI) questionnaire, and a melatonin salivary test with DLMO determination. Eighteen healthy subjects (HC) and 28 patients affected with cryptogenic focal epilepsy (FE) served as controls. The mean MEQ score was significantly lower in patients with IGE than that in patients with FE (49.1±5.9 versus 56.1±8.7 P<0.01) but not significantly lower than that in HC (49.1±5.9 versus 49.3±8.6). Midsleep on free days corrected for sleep duration did not differ significantly between the three subject groups (04:59±01:21h, 04:37±01:17h, 04:29±00:52h). The mean DLMO time in patients with IGE (22:13±01:34h) occurred 49min later than that in HC (21.24±1h), and the melatonin surge within the 30-minute time interval after DLMO in patients with IGE was significantly lower than that in HC (1.51±2.7 versus 3.8±3.6pg/mL P=0.045). Subjective measures of chronotype do not indicate a definite evening-oriented chronotype in patients with IGE. However, the data concerning endogenous melatonin secretion indicate that patients with IGE tend to have a late circadian phase. Further studies are warranted in order to better define the late pattern of endogenous melatonin secretion in patients with IGE and to ascertain the role of this pattern in influencing behavioral chronotype in these subjects.

    Gram-negative bacilli causing community-onset urinary tract infections (CoUTIs) are getting increasingly resistant to antimicrobial agents. Clinical significance and risk factors of the acquisition of antimicrobial-nonsusceptible pathogens are still under investigation. A prospective study was performed in the medical wards of two hospitals in southern Taiwan between August 2009 and January 2012. Patients were enrolled if they were aged >18, admitted through the emergency department, and had CoUTI due to Enterobacteriaceae isolates. Overall 136 adults with CoUTI were enrolled. Their mean age was 67 years and females were predominant (68.4%). Comorbidities, such as diabetes mellitus (30.1%) and hypertension (54.4%), were common. Escherichia coli (111, 81.6%) was the predominant species, followed by Klebsiella pneumoniae (11, 8.1%), and Proteus mirabilis (7, 5.1%). Nine (8.0%) of E. coli isolates and 5 (45%) of K. pneumoniae isolates had extended-spectrum β-lactamase (ESBL) production. Out of 122 non-ESBL producing isolates, 35 (28.7%) and 31 (25.4%) were nonsusceptible to levofloxacin and cefazolin, respectively. In the multivariate analysis, several clinical characters were found to be independently associated with CoUTIs due to levofloxacin-nonsusceptible (i.e. males, recent hospitalization, underlying old stroke, diabetes mellitus, and altered consciousness, or absence of chills, pyuria, or tachycardia), cefazolin-nonsusceptible (i.e. males, recent hospitalization, underlying old stroke, absence of fever or chills), or ESBL-producing isolates (i.e. recent hospitalization or antimicrobial therapy). All patients survived and discharged. However, the patients with CoUTIs due to levofloxacin-nonsusceptible (16.1 vs. 7.5 days, p < 0.01), cefazolin-nonsusceptible (15.4 vs. 8.4 days, p < 0.01) or ESBL-producing (16.7 vs. 9.6 days; p < 0.01) pathogens had a longer hospitalization stay than those due to their susceptible comparators. Several host factors were recognized

    Trichomonas vaginalis is a protozoan parasite that is the causative agent of trichomoniasis, a widespread sexually transmitted disease. In vitro culture of T. vaginalis typically employs a medium supplemented with either maltose or glucose and carbohydrates are considered essential for growth. Although the nature of the carbohydrates utilized by T. vaginalis in vivo is undefined, the vaginal epithelium is rich in glycogen, which appears to provide a source of carbon for the vaginal microbiota. Here, we show that T. vaginalis grows equally well in growth media supplemented with simple sugars or with glycogen. Analysis of conditioned growth medium by thin layer chromatography indicates that growth on glycogen is accompanied by glycogen breakdown to a mixture of products including maltose, glucose, and oligosaccharides. Enzymatic assays with conditioned growth medium show that glycogen breakdown is accomplished via the release of a glucosidase activity having the properties of an α-amylase into the growth medium. Furthermore, we find that released glucosidase activity increases upon removal of carbohydrate from the growth medium, indicating regulation of synthesis and/or secretion in response to environmental cues. Lastly, we show that addition of T. vaginalis glucosidase activity to a growth medium containing glycogen generates sufficient simple sugar to support the growth of lactobacilli which, themselves, are unable to degrade glycogen. Thus, not only does the glucosidase activity likely play an important role in allowing T. vaginalis to secure simple sugars for its own use, it has the potential to impact the growth of other members of the vaginal microbiome.

    The product of the CG9238 gene that we termed glycogen binding subunit 70E (Gbs-70E) was characterized by biochemical and molecular genetics methods. The interaction between Gbs-70E and all catalytic subunits of protein phosphatase 1 (Pp1-87B, Pp1-9C, Pp1-96A and Pp1-13C) of Drosophila melanogaster was confirmed by pairwise yeast two-hybrid tests, co-immunoprecipitation and pull down experiments. The binding of Gbs-70E to glycogen was demonstrated by sedimentation analysis. With RT-PCR we found that the mRNAs coding for the longer Gbs-70E PB/PC protein were expressed in all developmental stages of the fruit flies while the mRNA for the shorter Gbs-70E PA was restricted to the eggs and the ovaries of the adult females. The development specific expression of the shorter splice variant was not conserved in different Drosophila species. The expression level of the gene was manipulated by P-element insertions and gene deletion to analyze the functions of the gene product. A small or moderate reduction in the gene expression resulted in no significant changes, however, a deletion mutant expressing very low level of the transcript lived shorter and exhibited reduced glycogen content in the imagos. In addition, the gene deletion decreased the fertility of the fruit flies. Our results prove that Gbs-70E functions as the glycogen binding subunit of protein phosphatase 1 that regulates glycogen content and plays a role in the development of eggs in D. melanogaster.

  20. Glycogen and glucose metabolism are essential for early embryonic development of the red flour beetle Tribolium castaneum.

    Full Text Available Control of energy metabolism is an essential process for life. In insects, egg formation (oogenesis and embryogenesis is dependent on stored molecules deposited by the mother or transcribed later by the zygote. In oviparous insects the egg becomes an isolated system after egg laying with all energy conversion taking place during embryogenesis. Previous studies in a few vector species showed a strong correlation of key morphogenetic events and changes in glucose metabolism. Here, we investigate glycogen and glucose metabolism in the red flour beetle Tribolium castaneum, an insect amenable to functional genomic studies. To examine the role of the key enzymes on glycogen and glucose regulation we cloned and analyzed the function of glycogen synthase kinase 3 (GSK-3 and hexokinase (HexA genes during T. castaneum embryogenesis. Expression analysis via in situ hybridization shows that both genes are expressed only in the embryonic tissue, suggesting that embryonic and extra-embryonic cells display different metabolic activities. dsRNA adult female injection (parental RNAi of both genes lead a reduction in egg laying and to embryonic lethality. Morphological analysis via DAPI stainings indicates that early development is impaired in Tc-GSK-3 and Tc-HexA1 RNAi embryos. Importantly, glycogen levels are upregulated after Tc-GSK-3 RNAi and glucose levels are upregulated after Tc-HexA1 RNAi, indicating that both genes control metabolism during embryogenesis and oogenesis, respectively. Altogether our results show that T. castaneum embryogenesis depends on the proper control of glucose and glycogen.

    An adenosine diphosphate sugar pyrophosphatase (ASPPase, EC 3.6.1.21) has been characterized by using Escherichia coli. This enzyme, whose activities in the cell are inversely correlated with the intracellular glycogen content and the glucose concentration in the culture medium, hydrolyzes ADP-glucose, the precursor molecule of glycogen biosynthesis. ASPPase was purified to apparent homogeneity (over 3,000-fold), and sequence analyses revealed that it is a member of the ubiquitously distributed group of nucleotide pyrophosphatases designated as “nudix” hydrolases. Insertional mutagenesis experiments leading to the inactivation of the ASPPase encoding gene, aspP, produced cells with marginally low enzymatic activities and higher glycogen content than wild-type bacteria. aspP was cloned into an expression vector and introduced into E. coli. Transformed cells were shown to contain a dramatically reduced amount of glycogen, as compared with the untransformed bacteria. No pleiotropic changes in the bacterial growth occurred in both the aspP-overexpressing and aspP-deficient strains. The overall results pinpoint the reaction catalyzed by ASPPase as a potential step of regulating glycogen biosynthesis in E. coli. PMID:11416161

    The most common progressive myoclonus epilepsies are the late infantile and late infantile-variant neuronal ceroid lipofuscinoses (onset before the age of 6 years), Unverricht–Lundborg disease (onset after the age of 6 years) and Lafora disease. Lafora disease is a distinct disorder with uniform course: onset in teenage years, followed by progressively worsening myoclonus, seizures, visual hallucinations and cognitive decline, leading to a vegetative state in status myoclonicus and death within 10 years. Biopsy reveals Lafora bodies, which are pathognomonic and not seen with any other progressive myoclonus epilepsies. Lafora bodies are aggregates of polyglucosans, poorly constructed glycogen molecules with inordinately long strands that render them insoluble. Lafora disease is caused by mutations in the EPM2A or EPM2B genes, encoding the laforin phosphatase and the malin ubiquitin ligase, respectively, two cytoplasmically active enzymes that regulate glycogen construction, ensuring symmetric expansion into a spherical shape, essential to its solubility. In this work, we report a new progressive myoclonus epilepsy associated with Lafora bodies, early-onset Lafora body disease, map its locus to chromosome 4q21.21, identify its gene and mutation and characterize the relationship of its gene product with laforin and malin. Early-onset Lafora body disease presents early, at 5 years, with dysarthria, myoclonus and ataxia. The combination of early-onset and early dysarthria strongly suggests late infantile-variant neuronal ceroid lipofuscinosis, not Lafora disease. Pathology reveals no ceroid lipofuscinosis, but Lafora bodies. The subsequent course is a typical progressive myoclonus epilepsy, though much more protracted than any infantile neuronal ceroid lipofuscinosis, or Lafora disease, patients living into the fourth decade. The mutation, c.781T>C (Phe261Leu), is in a gene of unknown function, PRDM8. We show that the PRDM8 protein interacts with laforin and malin and

    Full Text Available Aim. The gene polymorphism of Asp299Gly TLR-4 may be associated with the risk of asthma development. Methods and results. The gene polymorphism of TLR-4 (Asp299Gly receptor has been researched in 262 early-onset and in 69 late-onset asthma patients. The state of anti-endotoxin immunity was assessed by determination of specific antibodies to the endotoxin of A, M, G classes and sCD14 by ELISA. The polymorphism was analyzed by the allele-specific polymerase chain reaction with electrophoretic detection. It was estimated that the risk of early-onset asthma in the population of Crimea is associated with genotypes AG and GG (Asp299Gly of TLR-4. There were increased levels of anti-endotoxin IgM and decreased of sIgA in patients with late-onset asthma and AA genotype as compared to other genotypes. Conclusion. The gene polymorphism of Asp299Gly TLR-4 is associated with the risk of early-onset asthma development in Crimea population.

    2013-09-01

    Glycogen metabolism contributes to energy storage and various physiological functions in some prokaryotes, including colonization persistence. A role for glycogen metabolism is proposed on the survival and fitness of Lactobacillus acidophilus, a probiotic microbe, in the human gastrointestinal environment. L. acidophilus NCFM possesses a glycogen metabolism (glg) operon consisting of glgBCDAP-amy-pgm genes. Expression of the glg operon and glycogen accumulation were carbon source- and growth phase-dependent, and were repressed by glucose. The highest intracellular glycogen content was observed in early log-phase cells grown on trehalose, which was followed by a drastic decrease of glycogen content prior to entering stationary phase. In raffinose-grown cells, however, glycogen accumulation gradually declined following early log phase and was maintained at stable levels throughout stationary phase. Raffinose also induced an overall higher temporal glg expression throughout growth compared with trehalose. Isogenic ΔglgA (glycogen synthase) and ΔglgB (glycogen-branching enzyme) mutants are glycogen-deficient and exhibited growth defects on raffinose. The latter observation suggests a reciprocal relationship between glycogen synthesis and raffinose metabolism. Deletion of glgB or glgP (glycogen phosphorylase) resulted in defective growth and increased bile sensitivity. The data indicate that glycogen metabolism is involved in growth maintenance, bile tolerance and complex carbohydrate utilization in L. acidophilus.

    Science.gov (United States)

    Goh, Yong Jun; Klaenhammer, Todd R

    2014-11-20

    In prokaryotic species equipped with glycogen metabolism machinery, the co-regulation of glycogen biosynthesis and degradation has been associated with the synthesis of energy storage compounds and various crucial physiological functions, including global cellular processes such as carbon and nitrogen metabolism, energy sensing and production, stress response and cell-cell communication. In addition, the glycogen metabolic pathway was proposed to serve as a carbon capacitor that regulates downstream carbon fluxes, and in some microorganisms the ability to synthesize intracellular glycogen has been implicated in host persistence. Among lactobacilli, complete glycogen metabolic pathway genes are present only in select species predominantly associated with mammalian hosts or natural environments. This observation highlights the potential involvement of glycogen biosynthesis in probiotic activities and persistence of intestinal lactobacilli in the human gastrointestinal tract. In this review, we summarize recent findings on (i) the presence and potential ecological distribution of glycogen metabolic pathways among lactobacilli, (ii) influence of carbon substrates and growth phases on glycogen metabolic gene expression and glycogen accumulation in L. acidophilus, and (iii) the involvement of glycogen metabolism on growth, sugar utilization and bile tolerance. Our present in vivo studies established the significance of glycogen biosynthesis on the competitive retention of L. acidophilus in the mouse intestinal tract, demonstrating for the first time that the ability to synthesize intracellular glycogen contributes to gut fitness and retention among probiotic microorganisms.

    Colorectal cancer (CRC) incidence and mortality are rising among young adults. Our aim was to contrast the relative incidence and mortality of CRC to other common cancers among young adults in the USA. We used Surveillance, Epidemiology, and End Results registry data to compare cancer site-specific and age-specific mortality and incident rates for adults younger than age 50. We summarized extracted data, both overall, and stratified by sex. We found CRC was the third leading cause of cancer death among adults younger than age 50, after breast and lung cancer (1.67 cases per 100,000). Among young women, CRC was the fourth leading cause of cancer death (1.51 per 100,000). Among young men, CRC was the second leading cause of cancer death (1.82 cases per 100,000). CRC was the second most incident cancer among young adults for men and women combined. Among men, CRC was the second most incident cancer after age 30, with 4.9, 9.0, 16.4, and 30.8 cases per 100,000 for ages 30-34, 35-39, 40-44, and 45-49 years, respectively. Among women, CRC incidence was similar with 4.2, 7.6, 15.3, and 25.9 cases per 100,000 for ages 30-34, 35-39, 40-44, and 45-49 years, respectively. These results show that CRC is a leading cause of cancer incidence and mortality among young adults in the USA, relative to other cancers. Given trends toward increasing rates of CRC among young adults, strategies for identifying individuals at risk for young-onset CRC who might benefit from early age of screening initiation merit investigation.

    Glycogen storage disease type I (GSDI), an inborn error of carbohydrate metabolism, is caused by defects in the glucose-6-transporter/glucose-6-phosphatase complex, which is essential in glucose homeostasis. Two types exist, GSDIa and GSDIb, each caused by different defects in the complex. GSDIa is

    Deficiency of microsomal glucose-6-phosphatase in liver and kidney leads to glycogen storage disease type 1a (GSD 1a). Notwithstanding intensive dietary therapy, moderate to severe dyslipidaemia and microalbuminuria, both known atherosclerotic risk factors, remain present. Although more patients rea

    BACKGROUND: Glycogen storage disease (GSD) is an inherited metabolic disorder in which the concentration and/or structure of glycogen in tissues is abnormal. Essentially, abnormalities in all known enzymes involved in the synthesis or degradation of glycogen and glucose have been found to cause some type of GSD. Liver and muscle have abundant quantities of glycogen and are the most common and seriously affected tissues. This study was to assess reduced-size liver transplantation for the treatment of GSD. METHODS: The clinical data from one case of GSD typeⅠ with hepatic adenoma was retrospectively analyzed. The clinical manifestations were hepatomegaly, delayed puberty, growth retardation, sexual immaturity, hypoglycemia, and lactic acidosis, which made the young female patient eligible for reduced-size liver transplantation. RESULTS: The patient recovered uneventfully with satisfactory outcome, including 12 cm growth in height and 5 kg increase in weight during 16 months after successful reduced-size liver transplantation. She has been living a normal life for 4 years so far. CONCLUSIONS: Reduced-size liver transplantation is an effective treatment for GSD with hepatomegaly and hepatic adenoma. Delayed puberty, growth retardation, hypoglycemia and lactic acidosis can be cured by surgery.
