2015-07-01

Marinesco-Sjoegren syndrome (MSS) is a recessively inherited multisystem disorder caused by mutations in SIL1 and characterized by cerebellar atrophy with ataxia, cataracts, a skeletal muscle myopathy, and variable degrees of developmental delay. Pathogenic mechanisms implicated to date include mitochondrial, nuclear envelope and lysosomal-autophagic pathway abnormalities. Here we present a 5-year-old girl with SIL1-related MSS and additional unusual features of an associated motor neuronopathy and a bradykinetic movement disorder preceding the onset of ataxia. These findings suggest that an associated motor neuronopathy may be part of the phenotypical spectrum of SIL1-related MSS and should be actively investigated in genetically confirmed cases. The additional observation of a bradykinetic movement disorder suggests an intriguing continuum between neurodevelopmental and neurodegenerative multisystem disorders intricately linked in the same cellular pathways.

Cohesin and Human Disease

Liu, Jinglan; Krantz, Ian D.

2016-01-01

Cornelia de Lange syndrome (CdLS) is a dominant multisystem disorder caused by a disruption of cohesin function. The cohesin ring complex is composed of four protein subunits and more than 25 additional proteins involved in its regulation. The discovery that this complex also has a fundamental role in long-range regulation of transcription in Drosophila has shed light on the mechanism likely responsible for its role in development. In addition to the three cohesin proteins involved in CdLS, a second multisystem, recessively inherited, developmental disorder, Roberts-SC phocomelia, is caused by mutations in another regulator of the cohesin complex, ESCO2. Here we review the phenotypes of these disorders, collectively termed cohesinopathies, as well as the mechanism by which cohesin disruption likely causes these diseases. PMID:18767966

[BIPOLAR DISORDER AS A MULTI-SYSTEM ILLNESS].

PubMed

Fenchel, Daphna; Levkovitz, Yechiel; Kotler, Moshe

2017-12-01

Bipolar disorder is a chronic condition, characterized by high distress in patients and high suicide rates (30%). Most patients suffer from medical and other psychiatric comorbidities, which worsen the psychiatric symptoms and decrease the likelihood of remission. More than 70% of bipolar patients have cardio-metabolic symptoms, with higher rates compared to other psychiatric disorders. Cardiovascular disease is the major cause of high mortality rates in these patients, with 1.5-2 fold increased risk of mortality, compared to the general population without psychiatric symptoms. The rates of cardiovascular risk factors and their resulting increased mortality rates are similar to those found in schizophrenia. In addition to cardio-metabolic conditions, 50% of patients with bipolar disorder suffer from other medical symptoms, which are also associated with worse outcomes. Therefore, the current perspective is that bipolar disorder is not only a psychiatric disorder, but rather a multi-system illness, affecting the entire body. The optimal treatment for these patients should include diagnosis, monitoring and treatment of both psychiatric and physical symptoms, which would improve their prognosis.

Artificial Gravity as a Multi-System Countermeasure for Exploration Class Space Flight Missions

NASA Technical Reports Server (NTRS)

Paloski, William H.; Dawson, David L. (Technical Monitor)

2000-01-01

NASA's vision for space exploration includes missions of unprecedented distance and duration. However, during 30 years of human space flight experience, including numerous long-duration missions, research has not produced any single countermeasure or combination of countermeasures that is completely effective. Current countermeasures do not fully protect crews in low-Earth orbit, and certainly will not be appropriate for crews journeying to Mars and back over a three-year period. The urgency for exploration-class countermeasures is compounded by continued technical and scientific successes that make exploration class missions increasingly attractive. The critical and possibly fatal problems of bone loss, cardiovascular deconditioning, muscle weakening, neurovestibular disturbance, space anemia, and immune compromise may be alleviated by the appropriate application of artificial gravity (AG). However, despite a manifest need for new countermeasure approaches, concepts for applying AG as a countermeasure have not developed apace. To explore the utility of AG as a multi-system countermeasure during long-duration, exploration-class space flight, eighty-three members of the international space life science and space flight community met earlier this year. They concluded unanimously that the potential of AG as a multi-system countermeasure is indeed worth pursuing, and that the requisite AG research needs to be supported more systematically by NASA. This presentation will review the issues discussed and recommendations made.

A review of “music and movement” therapies for children with autism: embodied interventions for multisystem development

PubMed Central

Srinivasan, Sudha M.; Bhat, Anjana N.

2013-01-01

The rising incidence of Autism Spectrum Disorders (ASDs) has led to a surge in the number of children needing autism interventions. This paper is a call to clinicians to diversify autism interventions and to promote the use of embodied music-based approaches to facilitate multisystem development. Approximately 12% of all autism interventions and 45% of all alternative treatment strategies in schools involve music-based activities. Musical training impacts various forms of development including communication, social-emotional, and motor development in children with ASDs and other developmental disorders as well as typically developing children. In this review, we will highlight the multisystem impairments of ASDs, explain why music and movement therapies are a powerful clinical tool, as well as describe mechanisms and offer evidence in support of music therapies for children with ASDs. We will support our claims by reviewing results from brain imaging studies reporting on music therapy effects in children with autism. We will also discuss the critical elements and the different types of music therapy approaches commonly used in pediatric neurological populations including autism. We provide strong arguments for the use of music and movement interventions as a multisystem treatment tool for children with ASDs. Finally, we also make recommendations for assessment and treatment of children with ASDs, and provide directions for future research. PMID:23576962

Toxoplasmosis is commonly asymptomatic; however, it can be a fatal multisystemic disease in some animal species, such as New World monkeys. An outbreak of acute fatal toxoplasmosis was reported in a colony of black-capped squirrel monkeys (Saimiri boliviensis) from the zoo of La Plata, Argentina. Post-mortem examination of two monkeys revealed macroscopical and microscopical lesions compatible with acute toxoplasmosis. The presence of Toxoplasma gondii was confirmed by immunohistochemistry on monkey tissues, bioassay in mice and PCR using the specific primers B22-B23. By PCR-RFLP analysis, T. gondii isolated in mice, deriving from both monkeys, showed the same restriction pattern, with most markers showing a type III restriction pattern, except for C22-8 (type II) and C29-2 (type I). To our knowledge this is the first report of fatal toxoplasmosis in S. boliviensis caused by a non-canonical or atypical genotype of T. gondii. Copyright © 2015 Elsevier Ireland Ltd.

Familial hemophagocytic lymphohistiocytosis is a very unusual cause for demyelination and the clinician would do well to be aware of the condition, especially when children present with atypical findings on magnetic resonance imaging associated with fever, pancytopenia, and hepatosplenomegaly. This is a rare autosomal recessive, multisystem inflammatory disorder characterized by widespread organ infiltration by macrophages and activated lymphocytes. It is usually diagnosed in the first 2 years of life and is rapidly fatal if untreated. Reported here is the case of a 12-year-old boy, from a poor family, with a 6-year history of visual loss and fever for 5 months, and transient hemiparesis with hepatosplenomegaly and pancytopenia. Cranial magnetic resonance imaging showed multiple areas of hyperintense signal, predominantly involving white matter. The boy also had elevated triglycerides and ferritin, with low fibrinogen level. Bone marrow aspiration revealed hemophagocytosis. He was diagnosed as having familial hemophagocytic lymphohistiocytosis and treated with the HLH 2004 protocol. A sibling also had evidence of hemophagocytosis. Remission was achieved, but his parents could not afford the cost of hematopoietic stem cell transplantation. He relapsed after 8 months and later died.

Long term management of patients with cryopyrin-associated periodic syndromes (CAPS): focus on rilonacept (IL-1 Trap).

PubMed

Church, Leigh D; Savic, Sinisa; McDermott, Michael F

2008-12-01

Cryopyrin-associated periodic syndromes (CAPS) are a group of inherited inflammatory disorders consisting of familial cold-induced autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS), and neonatal-onset multisystem inflammatory disease (NOMID; also known as chronic infantile neurologic, cutaneous, articular [CINCA] syndrome). These rare disorders are associated with heterozygous mutations in the NLRP3 (CIAS1) gene, which encodes the protein NALP3 or cryopyrin, and inflammation driven by excessive production of the cytokine interleukin-1beta (IL-1beta). Amyloidosis is a serious complication with 25% of MWS patients developing amyloidosis, with occasional fatal consequences, whilst up to 20% of CINCA/NOMID patients die from various complications, before reaching the early adulthood. In some CINCA/NOMID adult survivors amyloidosis can also occur. Prior to the discovery of the CIAS1 gene mutations and the advent of IL-1 targeted therapy, treatment was aimed at suppressing inflammation, with limited success. The selective blockade of IL-1beta, with anakinra (IL-1 receptor antagonist), not only provided supportive evidence for the role of IL-1beta in CAPS, but also demonstrated the efficacy of targeting IL-1beta for treatment of these conditions. In February, 2008, 'Orphan Drug' approval from the Food and Drug Administration (FDA) for rilonacept (IL-1 Trap/Arcalyst(), Regeneron Pharmaceuticals, Inc) was given for the treatment of two CAPS disorders, FCAS and MWS in adults and children 12 years and older, making rilonacept the first therapy approved for the treatment of CAPS.

A 22-month-old male Spanish water dog was hospitalized after its physical examination revealed fever and movement difficulty. After 24h, the dog was found to have a high fever (39.5 °C) and was treated empirically with doxycycline/ciprofloxacin. At 48 h, after submission the fever rose to 41 °C and the animal presented with a stiff neck and dehydration. Peripheral blood and cerebrospinal fluid (CSF) were sampled and trophozoites with an Acanthamoeba-like morphology were observed in the CSF. PCR specific for Acanthamoeba, Naegleria fowleri and Balamuthia mandrillaris were performed and the CSF sample found positive for Acanthamoeba. Lungs, kidney, liver and spleen samples were collected post mortem. All collected organ samples were positive for Acanthamoeba by PCR, thus confirming a multisystemic infection. Water samples taken at a suspected site of infection yielded an almost identical PCR fragment to those of the clinical samples, indicating that this was probably where the infection originated. This is the first report of a fatal case of Acanthamoeba disseminated infection in a dog in Spain. Copyright © 2014 Elsevier B.V. All rights reserved.

Gas gangrene is a rare but often fatal soft-tissue infection. Because it is uncommon and the classic symptom of crepitus does not appear until the infection is advanced, prompt diagnosis requires a high index of suspicion. We present a case report of a middle-aged man who presented with acute onset lower-extremity pain that was initially thought to be due to deep vein thrombosis. After undergoing workup for pulmonary embolism, he was found to have massive gas gangrene of the lower extremity secondary to an occult colon adenocarcinoma and died within hours of presentation from multisystem organ failure.

Juvenile xanthogranuloma (JXG) is generally a benign, self-limited histiocytic disorder of the skin. We report two cases of multisystem JXG presenting with clinical features more commonly seen in Langerhans cell histiocytosis (LCH), including diabetes insipidus and lytic bony lesions. Histologically, the skin lesions demonstrated a histiocytic dermal infiltrate that stained for CD-68, but S-100 and CD1a stains were negative. Treatment according to LCH-based chemotherapy regimens resulted in prompt resolution of symptoms. A literature review of multisystem JXG cases treated with chemotherapy suggests that symptomatic patients can successfully be treated with LCH-based regimens that include both corticosteroids and vinca alkaloids.

Plasmodium coatneyi in Rhesus Macaques Replicates the Multisystemic Dysfunction of Severe Malaria in Humans

2013-01-01

Severe malaria, a leading cause of mortality among children and nonimmune adults, is a multisystemic disorder characterized by complex clinical syndromes that are mechanistically poorly understood. The interplay of various parasite and host factors is critical in the pathophysiology of severe malaria. However, knowledge regarding the pathophysiological mechanisms and pathways leading to the multisystemic disorders of severe malaria in humans is limited. Here, we systematically investigate infections with Plasmodium coatneyi, a simian malaria parasite that closely mimics the biological characteristics of P. falciparum, and develop baseline data and protocols for studying erythrocyte turnover and severe malaria in greater depth. We show that rhesus macaques (Macaca mulatta) experimentally infected with P. coatneyi develop anemia, coagulopathy, and renal and metabolic dysfunction. The clinical course of acute infections required suppressive antimalaria chemotherapy, fluid support, and whole-blood transfusion, mimicking the standard of care for the management of severe malaria cases in humans. Subsequent infections in the same animals progressed with a mild illness in comparison, suggesting that immunity played a role in reducing the severity of the disease. Our results demonstrate that P. coatneyi infection in rhesus macaques can serve as a highly relevant model to investigate the physiological pathways and molecular mechanisms of malaria pathogenesis in naïve and immune individuals. Together with high-throughput postgenomic technologies, such investigations hold promise for the identification of new clinical interventions and adjunctive therapies. PMID:23509137

Charles Darwin (CD), "father of modern biology," suffered from multisystem illness from early adulthood. The most disabling manifestation was cyclic vomiting syndrome (CVS). This study aims at finding the possible cause of CVS in CD. A literature search using the PubMed database was carried out, and CD's complaints, as reported in his personal writings and those of his relatives, friends, colleagues, biographers, were compared with various manifestations of mitochondrial disorders (MIDs), known to cause CVS, described in the literature. Organ tissues involved in CD's disease were brain, nerves, muscles, vestibular apparatus, heart, gut, and skin. Cerebral manifestations included episodic headache, visual disturbance, episodic memory loss, periodic paralysis, hysterical crying, panic attacks, and episodes of depression. Manifestations of polyneuropathy included numbness, paresthesias, increased sweating, temperature sensitivity, and arterial hypotension. Muscular manifestations included periods of exhaustion, easy fatigability, myalgia, and muscle twitching. Cardiac manifestations included episodes of palpitations and chest pain. Gastrointestinal manifestations were CVS, dental problems, abnormal seasickness, eructation, belching, and flatulence. Dermatological manifestations included painful lips, dermatitis, eczema, and facial edema. Treatments with beneficial effects to his complaints were rest, relaxation, heat, and hydrotherapy. CVS in CD was most likely due to a multisystem, nonsyndromic MID. This diagnosis is based upon the multisystem nature of his disease, the fact that CVS is most frequently the manifestation of a MID, the family history, the variable phenotypic expression between affected family members, the fact that symptoms were triggered by stress, and that only few symptoms could not be explained by a MID.

Antisocial behaviour and conduct disorders are the most common behavioural and mental health problems in children and young people globally. An efficacious intervention is needed to manage these antisocial behaviours that have costly consequences. Multisystemic Therapy (MST), an intensive home-based intervention for youths with psychosocial and behavioural problems, is recommended under National Institute for Health and Clinical Excellence guidelines for conduct disorder. However, reviews on the efficacy of MST are mixed. To review randomised controlled trials (RCTs) reporting efficacy of MST among youths presenting with antisocial behaviour and emotional disorder respectively. A systematic map term to subject heading search was conducted in PsycINFO, Embase, and Ovid Medline databases for articles up to November 2015. RCTs comparing MST vs.treatment as usual (TAU) in youths presenting with antisocial behaviour and emotional disorder were included. 12 RCTs ( n  = 1425) reported efficacy of MST vs. TAU in youths presenting with antisocial behaviour and emotional disorder. Clinically significant treatment effects of MST showed a reduction of antisocial behaviour which includes delinquency. MST, vs. psychiatric hospitalisation, was associated with a reduction of suicidal attempts in youths presenting with psychiatric emergencies. 4 studies showed that MST was less costly than TAU in the short term, with further analysis required for long-term cost-effectiveness. MST is an efficacious intervention for severe antisocial behaviours in reduction of delinquency and should be included in clinical practices. MST was shown to have a positive effect on emotional disorder but further research is needed to evaluate the efficacy of MST with emotional disorder. Further analysis is required to assess the services utilized for long-term cost effectiveness.

Hemophagocytic lymphohistiocytosis (HLH) is a multisystem disorder mediated by cytokine storm and is characterized by fever, pancytopenia and organomegaly coupled with laboratory features like hyperferritinemia, hypertriglyceridemia, hypofibrinogenemia and transaminitis. Etiology can be genetic or acquired such as infections, malignancy and autoimmune disorders. Diagnosis, identification of underlying etiology and management of HLH remain tough clinical puzzles to sort out for the managing physician. We report a clinico-pathological conference of a three-year-old boy who had such a presentation and succumbed during the hospital stay.

Obstetric nephrology: preeclampsia--the nephrologist's perspective.

Umans, Jason G

2012-12-01

Preeclampsia, a common and potentially devastating multisystem disorder unique to human pregnancy, represents a novel form of secondary hypertension with complex renal and systemic effects. Recent translational and clinical research reveals key pathophysiologic contributions due to dysregulation of angiogenic factors and of angiotensin signaling. Despite these insights, there are still difficulties in the clinical definition of preeclampsia and in the diagnosis of women with this disorder. Although recent research suggests the potential for new preventive and treatment strategies, most have not yet been shown ready for clinical use.

Elevated basal serum tryptase levels are present in 4-6% of the general population, but the cause and relevance of such increases are unknown. Previously, we described subjects with dominantly inherited elevated basal serum tryptase levels associated with multisystem complaints including cutaneous flushing and pruritus, dysautonomia, functional gastrointestinal symptoms, chronic pain, and connective tissue abnormalities, including joint hypermobility. Here we report the identification of germline duplications and triplications in the TPSAB1 gene encoding α-tryptase that segregate with inherited increases in basal serum tryptase levels in 35 families presenting with associated multisystem complaints. Individuals harboring alleles encoding three copies of α-tryptase had higher basal serum levels of tryptase and were more symptomatic than those with alleles encoding two copies, suggesting a gene-dose effect. Further, we found in two additional cohorts (172 individuals) that elevated basal serum tryptase levels were exclusively associated with duplication of α-tryptase-encoding sequence in TPSAB1, and affected individuals reported symptom complexes seen in our initial familial cohort. Thus, our findings link duplications in TPSAB1 with irritable bowel syndrome, cutaneous complaints, connective tissue abnormalities, and dysautonomia.

In animals, multisystemic eosinophilic disease is a rare condition characterized by eosinophilic and lymphoplasmacytic infiltrates in various organs. This disorder resembles the human disease known as hypereosinophilic syndrome, a condition defined by prolonged peripheral eosinophilia in the absence of recognizable etiology and associated with end-organ damage. In this report we describe a research-naïve, colony-born, juvenile female owl monkey (Aotus vociferans) who presented clinically with severe respiratory distress and histologically with multiple end-organ infiltration with phenotypically mature eosinophils, plasma cells, and lymphocytes. No tumors or infectious agents were noted either macroscopically or microscopically. Cultures from lung samples revealed no bacteria or fungi. Histologic examination of lung, heart, thymus, liver, spleen, kidney, adrenal, pancreas, stomach, small intestine, and colon revealed no migrating nematode larvae, other parasites, or foreign material that might trigger eosinophilia, nor was there any evidence of or history consistent with an allergic etiology. Given that we ruled out most exogenous and endogenous triggers of eosinophilia, the signs, symptoms, and pathologic findings support the diagnosis of multisystemic eosinophilic disease. To our knowledge, this report is the first description of presumptive hypereosinophilic syndrome in a nonhuman primate. PMID:19476722

Arteriovenous Pearson syndrome is a very rare multisystemic mitochondrial disease characterized by sideroblastic anemia and exocrine pancreatic insufficiency. It is usually fatal in infancy. We reported a four-month-old infant presented with fever and pancytopenia. Bone marrow examination showed hypoplastic changes and sideroblastic features. Molecular Study showed a novel hetroplasmic mitochondrial deletions (m. 10760 -m. 15889+) in multiple genes (ND4,ND5,ND6, CYTB). In our patient the pathogenic mutation was 5.1 kb heteroplasmic deletions in multiple genes that are important and crucial for intact oxidative phosphorylation pathway and ATP production in the mitochondrial DNA. This mutation was not reported in literature including the mitomap.org website (which was last edited on Nov 30, 2017 and accessed on Jan 13, 2018).

Multiple System Atrophy: An Oligodendroglioneural Synucleinopathy1

PubMed Central

Jellinger, Kurt A.

2017-01-01

Multiple system atrophy (MSA) is an orphan, fatal, adult-onset neurodegenerative disorder of uncertain etiology that is clinically characterized by various combinations of parkinsonism, cerebellar, autonomic, and motor dysfunction. MSA is an α-synucleinopathy with specific glioneuronal degeneration involving striatonigral, olivopontocerebellar, and autonomic nervous systems but also other parts of the central and peripheral nervous systems. The major clinical variants correlate with the morphologic phenotypes of striatonigral degeneration (MSA-P) and olivopontocerebellar atrophy (MSA-C). While our knowledge of the molecular pathogenesis of this devastating disease is still incomplete, updated consensus criteria and combined fluid and imaging biomarkers have increased its diagnostic accuracy. The neuropathologic hallmark of this unique proteinopathy is the deposition of aberrant α-synuclein in both glia (mainly oligodendroglia) and neurons forming glial and neuronal cytoplasmic inclusions that cause cell dysfunction and demise. In addition, there is widespread demyelination, the pathogenesis of which is not fully understood. The pathogenesis of MSA is characterized by propagation of misfolded α-synuclein from neurons to oligodendroglia and cell-to-cell spreading in a “prion-like” manner, oxidative stress, proteasomal and mitochondrial dysfunction, dysregulation of myelin lipids, decreased neurotrophic factors, neuroinflammation, and energy failure. The combination of these mechanisms finally results in a system-specific pattern of neurodegeneration and a multisystem involvement that are specific for MSA. Despite several pharmacological approaches in MSA models, addressing these pathogenic mechanisms, no effective neuroprotective nor disease-modifying therapeutic strategies are currently available. Multidisciplinary research to elucidate the genetic and molecular background of the deleterious cycle of noxious processes, to develop reliable biomarkers and targets for effective treatment of this hitherto incurable disorder is urgently needed.

Objective: We report novel defects of mitochondrial translation elongation factor Ts (EFTs), with high carrier frequency in Finland and expand the manifestations of this disease group from infantile cardiomyopathy to juvenile neuropathy/encephalopathy disorders. Methods: DNA analysis, whole-exome analysis, protein biochemistry, and protein modeling. Results: We used whole-exome sequencing to find the genetic cause of infantile-onset mitochondrial cardiomyopathy, progressing to juvenile-onset Leigh syndrome, neuropathy, and optic atrophy in 2 siblings. We found novel compound heterozygous mutations, c.944G>A [p.C315Y] and c.856C>T [p.Q286X], in the TSFM gene encoding mitochondrial EFTs. The same p.Q286X variant was found as compound heterozygous with a splice site change in a patient from a second family, with juvenile-onset optic atrophy, peripheral neuropathy, and ataxia. Our molecular modeling predicted the coding-region mutations to cause protein instability, which was experimentally confirmed in cultured patient cells, with mitochondrial translation defect and lacking EFTs. Only a single TSFM mutation has been previously described in different populations, leading to an infantile fatal multisystem disorder with cardiomyopathy. Sequence data from 35,000 Finnish population controls indicated that the heterozygous carrier frequency of p.Q286X change was exceptionally high in Finland, 1:80, but no homozygotes were found in the population, in our mitochondrial disease patient collection, or in an intrauterine fetal death material, suggesting early developmental lethality of the homozygotes. Conclusions: We show that in addition to early-onset cardiomyopathy, TSFM mutations should be considered in childhood and juvenile encephalopathies with optic and/or peripheral neuropathy, ataxia, or Leigh disease.

To clarify clinical polymorphism of amyotrophic lateral sclerosis (ALS). The study was based on records of a hospital personalized register. Ninety-four patients, aged from 25 to 81 years, diagnosed with ALS according to El Escorial criteria were included. Electromyography and, if necessary, transcranial magnetic stimulation and magnetic-resonance tomography were used to confirm the diagnosis. Disease progression was assessed with the ARSFRS. Age at disease onset, progression rate and duration of survival of patients, rare symptoms of ALS ('extramotor'), time for palliative care (gastrostomy, non-invasive and invasive lung ventilation) and provision of the care to the patient, family history were recorded in a specially designed questionnaire. Most of the patients had sporadic ALS, only two familial cases were identified. Spinal onset ALS was found in 66.0% of the patients, bulbar onset in 29.8%, diffuse onset (spinal and bulbar motor neurons were affected simultaneously) in 4.2%. Moderate ALS progression was observed in 42.6% of the patients, mean time till death was 3.0±1.2 years. A slow progression was found in patients with cervical, low back and bulbar onset. A rapid and even 'momentary' type of progression was in diffuse and breast onset. An extremely slow progression with the long-term hospital treatment and survival >5 years was found in 9.7%. Rare ALS symptoms were represented by specific cognitive and psychological impairments, a type of frontal/temporal dysfunction, but only 5 (5.3%) patients were diagnosed with ALS-dementia. Signs of pathological muscle fatigue (myasthenic syndrome) were identified in 18 (19.1%), extrapyramidal disorders in 5 (5.3%), coordination disorders in 4 (4.3%), pain in 12 (12.8%), sensory symptoms in 5 (5.3%) of the patients. ALS is a multisystemic neurodegeneration disease though the progressive motor neuron death determines the fatal outcome.

Coenzyme Q biosynthesis in health and disease.

2016-08-01

Coenzyme Q (CoQ, or ubiquinone) is a remarkable lipid that plays an essential role in mitochondria as an electron shuttle between complexes I and II of the respiratory chain, and complex III. It is also a cofactor of other dehydrogenases, a modulator of the permeability transition pore and an essential antioxidant. CoQ is synthesized in mitochondria by a set of at least 12 proteins that form a multiprotein complex. The exact composition of this complex is still unclear. Most of the genes involved in CoQ biosynthesis (COQ genes) have been studied in yeast and have mammalian orthologues. Some of them encode enzymes involved in the modification of the quinone ring of CoQ, but for others the precise function is unknown. Two genes appear to have a regulatory role: COQ8 (and its human counterparts ADCK3 and ADCK4) encodes a putative kinase, while PTC7 encodes a phosphatase required for the activation of Coq7. Mutations in human COQ genes cause primary CoQ(10) deficiency, a clinically heterogeneous mitochondrial disorder with onset from birth to the seventh decade, and with clinical manifestation ranging from fatal multisystem disorders, to isolated encephalopathy or nephropathy. The pathogenesis of CoQ(10) deficiency involves deficient ATP production and excessive ROS formation, but possibly other aspects of CoQ(10) function are implicated. CoQ(10) deficiency is unique among mitochondrial disorders since an effective treatment is available. Many patients respond to oral CoQ(10) supplementation. Nevertheless, treatment is still problematic because of the low bioavailability of the compound, and novel pharmacological approaches are currently being investigated.

CHST14/D4ST1 deficiency: New form of Ehlers-Danlos syndrome.

Kosho, Tomoki

2016-02-01

Carbohydrate sulfotransferase 14/dermatan 4-O-sulfotransferase-1 (CHST14/D4ST1) deficiency represents a specific form of Ehlers-Danlos syndrome (EDS) caused by recessive loss-of-function mutations in CHST14. The disorder has been independently termed "adducted thumb-clubfoot syndrome", "EDS, Kosho type", and "EDS, musculocontractural type". To date, 31 affected patients from 21 families have been described. Clinically, CHST14/D4ST1 deficiency is characterized by multiple congenital malformations (craniofacial features including large fontanelle, hypertelorism, short and downslanting palpebral fissures, blue sclerae, short nose with hypoplastic columella, low-set and rotated ears, high palate, long philtrum, thin upper lip vermilion, small mouth, and micro-retrognathia; multiple congenital contractures including adduction-flexion contractures and talipes equinovarus as well as other visceral or ophthalmological malformations) and progressive multisystem fragility-related complications (skin hyperextensibility, bruisability, and fragility with atrophic scars; recurrent dislocations; progressive talipes or spinal deformities; pneumothorax or pneumohemothorax; large subcutaneous hematomas; and diverticular perforation). Etiologically, multisystem fragility is presumably caused by impaired assembly of collagen fibrils resulting from loss of dermatan sulfate (DS) in the decorin glycosaminoglycan side chain that promotes electrostatic binding between collagen fibrils. This is the first reported human disorder that specifically affects biosynthesis of DS. Its clinical characteristics indicate that CHST14/D4ST1 and, more fundamentally, DS, play a critical role in fetal development and maintenance of connective tissues in multiple organs. Considering that patients with CHST14/D4ST1 deficiency develop progressive multisystem fragility-related manifestations, establishment of a comprehensive and detailed natural history and health-care guidelines as well as further elucidation of the pathophysiology in view of future etiology-based therapy are crucial. © 2015 Japan Pediatric Society.

Primary mitochondrial diseases refer to a group of heterogeneous and complex genetic disorders affecting 1:5000 people. The true prevalence is anticipated to be even higher because of the complexity of achieving a diagnosis in many patients who present with multisystemic complaints ranging from infancy to adulthood. Diabetes is a prominent feature of several of these disorders which might be overlooked by the endocrinologist. We here review mitochondrial disorders and describe the phenotypic and pathogenetic differences between mitochondrial diabetes mellitus (mDM) and other more common forms of diabetes mellitus. © 2014 John Wiley & Sons A/S.

Evaluation of multisystemic therapy pilot services in the Systemic Therapy for At Risk Teens (START) trial: study protocol for a randomised controlled trial

PubMed Central

2013-01-01

Background There is an urgent need for clinically effective and cost-effective methods to manage antisocial and criminal behaviour in adolescents. Youth conduct disorder is increasingly prevalent in the UK and is associated with a range of negative outcomes. Quantitative systematic reviews carried out for the National Institute for Health and Clinical Excellence have identified multisystemic therapy, an intensive, multimodal, home-based, family intervention for youth with serious antisocial behaviour, as one of the most promising interventions for reducing antisocial or offending behaviour and improving individual and family functioning. Previous international trials of multisystemic therapy have yielded mixed outcomes, and it is questionable to what extent positive US findings can be generalised to a wider UK mental health and juvenile justice context. This paper describes the protocol for the Systemic Therapy for At Risk Teens (START) trial, a multicentre UK-wide randomised controlled trial of multisystemic therapy in antisocial adolescents at high risk of out-of-home placement. Methods/Design The trial is being conducted at 10 sites across the UK. Seven hundred participants and their families will be recruited and randomised on a 1:1 basis to multisystemic therapy or management as usual. Treatments are offered over a period of 3 to 5 months, with follow-up to 18 months post-randomisation. The primary outcome is out-of-home placement at 18 months. Secondary outcomes include offending rates, total service and criminal justice sector costs, and participant well-being and educational outcomes. Data will be gathered from police computer records, the National Pupil Database, and interview and self-report measures administered to adolescents, parents and teachers. Outcomes will be analysed on an intention-to-treat basis, using a logistic regression with random effects for the primary outcome and Cox regressions and linear mixed-effects models for secondary outcomes depending on whether the outcome is time-to-event or continuous. Discussion The START trial is a pragmatic national trial of sufficient size to evaluate multisystemic therapy, to inform policymakers, service commissioners, professionals, service users and their families about its potential in the UK. It will also provide data on the clinical and cost-effectiveness of usual services provided to youth with serious antisocial behaviour problems. Trial registration ISRCTN77132214 PMID:23962220

Tuberous sclerosis complex is a multisystem, chronic genetic condition characterized by systemic growth of benign tumors and often accompanied by epilepsy, autism spectrum disorders, and intellectual disability. Nonetheless, the neurodevelopmental phenotype of these patients is not often detailed. The authors describe 3 individuals with tuberous sclerosis complex who share common characteristics that can help to identify a distinct profile of autism spectrum disorder. These findings include typical cognitive development, expressive and pragmatic language deficits, and anxiety. The authors also describe features specific to tuberous sclerosis complex that require consideration before diagnosing an autism spectrum disorder. Identifying distinct profiles of autism spectrum disorder in tuberous sclerosis complex can help optimize treatment across the life span. © The Author(s) 2015.

Attention-Deficit/Hyperactivity Disorder and Fatal Accidents in Aviation Medicine.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with symptoms of inattention and/or hyperactivity-impulsivity that interfere with functioning and/or development. ADHD occurs in about 2.5% of adults. ADHD can be an excluding medical condition among pilots due to the risk of attentional degradation and therefore impact on flight safety. Diagnosis of ADHD is complex, which complicates aeromedical assessment. This study highlights fatal accident cases among pilots with ADHD and discusses protocols to detect its presence to help to assess its importance to flight safety. To identify fatal accidents in aviation (including airplanes, helicopters, balloons, and gliders) in the United States between the years 2000 to 2015, the National Transportation Safety Board (NTSB) database was searched with the terms ADHD, attention deficit hyperactivity disorder, and attention deficit disorder (ADD). The NTSB database search for fatal aviation accidents possibly associated with ADHD yielded four accident cases of interest in the United States [4/4894 (0.08%)]. Two of the pilots had ADHD diagnosed by a doctor, one was reported by a family member, and one by a flight instructor. An additional five cases were identified searching for ADD [5/4894 (0.1%)]. Altogether, combined ADHD and ADD cases yielded nine accident cases of interest (0.18%). It is generally accepted by aviation regulatory authorities that ADHD is a disqualifying neurological condition. Yet FAA and CASA provide specific protocols for tailor-made pilot assessment. Accurate evaluation of ADHD is essential because of its potential negative impact on aviation safety.Laukkala T, Bor R, Budowle B, Sajantila A, Navathe P, Sainio M, Vuorio A.

We report on a female patient with lipomas and slightly progressive myoclonus, neuropathy, myopathy, ataxia and respiratory systemic involvement (labelled in the past as Madelung's disease). Multisystem involvement and family history of lipomas led to the development of mitochondrial genetic tests, which can assess two concurrent mitochondrial mutations: the m.8344A>G mutation in MT-TK gene, related MERRF (myoclonic epilepsy with ragged-red fibre) phenotype and m.14484T>C mutation in the MT-ND6 gene responsible for Leber hereditary optic neuropathy phenotype. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Pseudoxanthoma elasticum (PXE) is a rare genetic disorder characterized by fragmented and mineralized elastic fibers in the mid-dermis of the skin, eye, digestive tract and cardiovascular system. Clinical presentation includes typical skin lesions, ocular angioid streaks, and multisystem vasculopathy. The age of onset varies considerably from infancy to old age, but the diagnosis is usually made in young adults due to frequent absence of pathognomonic skin and ocular manifestations in early childhood. We report two children with PXE presenting with isolated multisystem vasculopathy and early-onset stroke. In the first patient, diagnosis was delayed until typical dermatologic alterations appeared; in the second patient, next-generation sequencing (NGS) study led to early diagnosis and specific follow-up, underlying the crucial role in idiopathic pediatric stroke of early genetic testing using NGS-based panels.

Wenninger, Stephan; Montagnese, Federica; Schoser, Benedikt

2018-01-01

Myotonic dystrophy type 1 (DM1) and type 2 (DM2) represent the most frequent multisystemic muscular dystrophies in adulthood. They are progressive, autosomal dominant diseases caused by an abnormal expansion of an unstable nucleotide repeat located in the non-coding region of their respective genes DMPK for DM1 and CNBP in DM2. Clinically, these multisystemic disorders are characterized by a high variability of muscular and extramuscular symptoms, often causing a delay in diagnosis. For both subtypes, many symptoms overlap, but some differences allow their clinical distinction. This article highlights the clinical core features of myotonic dystrophies, thus facilitating their early recognition and diagnosis. Particular attention will be given to signs and symptoms of muscular involvement, to issues related to respiratory impairment, and to the multiorgan involvement.

hnRNPA2B1 and hnRNPA1 mutations have been recently identified by exome sequencing in three families presenting with multisystem proteinopathy (MSP), a rare complex phenotype associating frontotemporal lobar degeneration (FTLD), Paget disease of bone (PDB), inclusion body myopathy (IBM), and amyotrophic lateral sclerosis (ALS). No study has evaluated the exact frequency of these genes in cohorts of MSP or FTD patients so far. We sequenced both genes in 17 patients with MSP phenotypes, and in 60 patients with FTLD and FTLD-ALS to test whether mutations could be implicated in the pathogenesis of these disorders. No disease-causing mutation was identified. We conclude that hnRNPA2B1 and hnRNPA1 mutations are rare in MSP and FTLD spectrum of diseases, although further investigations in larger populations are needed. Copyright © 2014 Elsevier Inc.

ALF is a multisystem disorder necessitating both predictive and reactive management strategies to support and protect organs from the initial and subsequent insults encountered. Early referral to a specialist liver centre with the option of liver transplantation is recommended. Furthermore, a good understanding of the poor prognostic variables is necessary to determine those most at risk of developing ALF in order to facilitate timely, safe transfer and listing for liver transplantation.

2016-08-02

The importance of telomere function for human health is exemplified by a collection of Mendelian disorders referred to as the telomere biology disorders (TBDs), telomeropathies, or syndromes of telomere shortening. Collectively, the TBDs cover a spectrum of conditions from multisystem disease presenting in infancy to isolated disease presentations in adulthood, most notably idiopathic pulmonary fibrosis. Eleven genes have been found mutated in the TBDs to date, each of which is linked to some aspect of telomere maintenance. This review summarizes the molecular defects that result from mutations in these genes, highlighting recent advances, including the addition of PARN to the TBD gene family and the discovery of heterozygous mutations in RTEL1 as a cause of familial pulmonary fibrosis.

This article presents an up-to-date summary of the genetic etiology, diagnostic criteria, clinical features, and current management recommendations for the most common neurocutaneous disorders encountered in clinical adult and pediatric neurology practices. The phakomatoses are a phenotypically and genetically diverse group of multisystem disorders that primarily affect the skin and central nervous system. A greater understanding of the genetic and biological underpinnings of numerous neurocutaneous disorders has led to better clinical characterization, more refined diagnostic criteria, and improved treatments in neurofibromatosis type 1, Legius syndrome, neurofibromatosis type 2, Noonan syndrome with multiple lentigines, tuberous sclerosis complex, Sturge-Weber syndrome, and incontinentia pigmenti. Neurologists require a basic knowledge of and familiarity with a wide variety of neurocutaneous disorders because of the frequent involvement of the central and peripheral nervous systems. A simple routine skin examination can often open a broad differential diagnosis and lead to improved patient care.

The lysosomal storage disorders are a collection of progressive, multisystem disorders that frequently present in childhood. Their timely diagnosis is paramount as they are becoming increasingly treatable. Musculoskeletal manifestations often occur early in the disease course, hence are useful as diagnostics clues. Non-inflammatory joint stiffness or pain, carpal tunnel syndrome, trigger fingers, unexplained pain crises and short stature should all prompt consideration of a lysosomal storage disorder. Recurrent ENT infections, hepatosplenomegaly, recurrent hernias and visual/hearing impairment - especially when clustered together - are important extra-skeletal features. As diagnostic and therapeutic options continue to evolve, children with lysosomal storage disorders and their families are facing more sophisticated options for screening and treatment. The aim of this article is to highlight the paediatric presentations of lysosomal storage disorders, with an emphasis on the musculoskeletal features. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Dental Perspectives in Fibrous Dysplasia and McCune-Albright Syndrome

Akintoye, Sunday O.; Boyce, Alison M.; Collins, Michael T.

2013-01-01

McCune-Albright syndrome (MAS) is a rare multisystem disorder characterized by the triad of polyostotic fibrous dysplasia (PFD), endocrine disorders and café-au-lait skin pigmentation. Ninety percent of MAS patients have FD lesions in the craniofacial area, resulting in significant orofacial deformity, dental disorders, bone pain and compromised oral health. Maxillo-mandibular FD is also associated with dental developmental disorders, malocclusion, and high caries index. There is limited data on the outcomes of dental treatments in maxillo-mandibular FD/MAS patients, because clinicians and researchers have limited access to patients, and there are concerns that dental surgery may activate quiescent jaw FD lesions to grow aggressively. This report highlights current perspectives on dental management issues associated with maxillo-mandibular FD within the context of MAS. PMID:23953425

SeSAME/EAST syndrome is a multisystemic disorder in humans, characterised by seizures, sensorineural deafness, ataxia, developmental delay and electrolyte imbalance. It is exclusively caused by homozygous or compound heterozygous variations in the KCNJ10 gene. Here we describe a similar syndrome in two families belonging to the Malinois dog breed, based on clinical, neurological, electrodiagnostic and histopathological examination. Genetic analysis detected a novel pathogenic KCNJ10 c.986T>C (p.(Leu329Pro)) variant that is inherited in an autosomal recessive way. This variant has an allele frequency of 2.9% in the Belgian Malinois population, but is not found in closely related dog breeds or in dog breeds where similar symptoms have been already described. The canine phenotype is remarkably similar to humans, including ataxia and seizures. In addition, in half of the dogs clinical and electrophysiological signs of neuromyotonia were observed. Because there is currently no cure and treatment is nonspecific and unsatisfactory, this canine translational model could be used for further elucidating the genotype/phenotype correlation of this monogenic multisystem disorder and as an excellent intermediate step for drug safety testing and efficacy evaluations before initiating human studies.

H syndrome is an autosomal recessive genodermatosis with multisystem involvement caused by mutations in SLC29A3. We sought to investigate the clinical and molecular findings in 79 patients with this disorder. A total of 79 patients were included, of which 13 are newly reported cases. Because of the phenotypic similarity and molecular overlap with H syndrome, we included 18 patients with allelic disorders. For 31 patients described by others, data were gathered from the medical literature. The most common clinical features (>45% of patients) were hyperpigmentation, phalangeal flexion contractures, hearing loss, and short stature. Insulin-dependent diabetes mellitus and lymphadenopathy mimicking Rosai-Dorfman disease were each found in approximately 20%. Additional systemic features were described in less than 15% of cases. Marked interfamilial and intrafamilial clinical variability exists. Twenty mutations have been identified in SLC29A3, with no genotype-phenotype correlation. In the 31 patients described by others, data were collected from the medical literature. H syndrome is a multisystemic disease with clinical variability. Consequently, all SLC29A3-related diseases should be considered a single entity. Recognition of the pleomorphic nature of H syndrome is important for diagnosis of additional patients.

Agrusa, A; Mularo, S; Alessi, R; Di Paola, P; Mularo, A; Amato, G; Romano, G

2011-01-01

Myotonic dystrophy (MD) is a serious multi-systemic autosomal dominant disease. The estimated incidence is 1 in every 8000 births, with an estimated prevalence of between 2.1 and 14.3 cases per 100,000 inhabitants. Signs and symptoms vary from a severe form of congenital myopathy, present from birth and often fatal, to a classic form and a delayed form, which generally presents after the age of 50 and in which the only sign is a cataract and life expectancy is completely normal. We describe the clinical case of a 40-year-old woman with Steinert myotonic dystrophy who underwent laparoscopic cholecystectomy (under general anesthesia) for symptomatic gallbladder stones. The conduct of anesthesia in such patients must be carefully considered, as hypothermia, shivering, electrical and mechanical stimulation, and the drugs used can all trigger myotonia.

The challenge of treating conduct disorder in low-resourced settings: rap music to the rescue.

PubMed

Evans, Dylan J

2010-12-01

Conduct disorder is one of the most frequent serious childhood problems that present for treatment in community clinic settings. Evidence-based treatments for conduct disorder are intensive and require considerable resources to implement. In low-resourced contexts it is often not feasible to implement evidence-based treatments in their current form, which poses significant challenges for clinicians attempting to treat children in these settings. This article explores these challenges using a case study of the treatment of a young adolescent boy with a short-term multisystem intervention where rap music was employed as a powerful tool to facilitate an empathic connection in therapy and as a projective technique to explore underlying emotional difficulties.

Rapamycin and Chloroquine: The In Vitro and In Vivo Effects of Autophagy-Modifying Drugs Show Promising Results in Valosin Containing Protein Multisystem Proteinopathy

PubMed Central

Nalbandian, Angèle; Llewellyn, Katrina J.; Nguyen, Christopher; Yazdi, Puya G.; Kimonis, Virginia E.

Mutations in the valosin containing protein (VCP) gene cause hereditary Inclusion body myopathy (hIBM) associated with Paget disease of bone (PDB), frontotemporal dementia (FTD), more recently termed multisystem proteinopathy (MSP). Affected individuals exhibit scapular winging and die from progressive muscle weakness, and cardiac and respiratory failure, typically in their 40s to 50s. Histologically, patients show the presence of rimmed vacuoles and TAR DNA-binding protein 43 (TDP-43)-positive large ubiquitinated inclusion bodies in the muscles. We have generated a VCPR155H/+ mouse model which recapitulates the disease phenotype and impaired autophagy typically observed in patients with VCP disease. Autophagy-modifying agents, such as rapamycin and chloroquine, at pharmacological doses have previously shown to alter the autophagic flux. Herein, we report results of administration of rapamycin, a specific inhibitor of the mechanistic target of rapamycin (mTOR) signaling pathway, and chloroquine, a lysosomal inhibitor which reverses autophagy by accumulating in lysosomes, responsible for blocking autophagy in 20-month old VCPR155H/+ mice. Rapamycin-treated mice demonstrated significant improvement in muscle performance, quadriceps histological analysis, and rescue of ubiquitin, and TDP-43 pathology and defective autophagy as indicated by decreased protein expression levels of LC3-I/II, p62/SQSTM1, optineurin and inhibiting the mTORC1 substrates. Conversely, chloroquine-treated VCPR155H/+ mice revealed progressive muscle weakness, cytoplasmic accumulation of TDP-43, ubiquitin-positive inclusion bodies and increased LC3-I/II, p62/SQSTM1, and optineurin expression levels. Our in vitro patient myoblasts studies treated with rapamycin demonstrated an overall improvement in the autophagy markers. Targeting the mTOR pathway ameliorates an increasing list of disorders, and these findings suggest that VCP disease and related neurodegenerative multisystem proteinopathies can now be included as disorders that can potentially be ameliorated by rapalogs.

2017-01-01

COPD is highly prevalent and associated with substantial morbidity and mortality. Clinicians have long been aware that patients with COPD have problems with cognition and are susceptible to mood (depression) and anxiety disorders. With the increasing awareness of COPD as a multisystem disorder, many studies have evaluated the prevalence of neuropsychiatric conditions in patients with COPD. This review presents evidence regarding the prevalence of neuropsychiatric conditions (cognitive disorders/impairment, depression/anxiety) in COPD, their risk factors, and their impact on relevant outcomes. It also discusses both assessment and treatment of neuropsychiatric conditions and makes recommendations for improved screening and treatment. The findings suggest that clinicians caring for patients with COPD must become familiar with diagnosing these comorbid conditions and that future treatment has the potential to impact these patients and thereby improve COPD outcomes.

Winthrop, Zachary A.; Salman, Rabia; Majeed, Salman

2016-01-01

Alagille syndrome is a rare multisystem disorder affecting the liver, heart, vertebrae, eyes, and face. Alagille syndrome shares multiple phenotypic variants of other congenital or chronic childhood illnesses such as DiGeorge syndrome, Down syndrome, spina bifida, type 1 diabetes mellitus, and cystic fibrosis. All of these chronic illnesses have well-established links to psychiatric conditions. There are few community resources for Alagille patients, as it is an extremely rare condition. Despite the overlap with other chronic childhood illnesses, the psychiatric manifestations of Alagille syndrome have not been previously discussed in literature. The current study is a case report of a twelve-year-old female hospitalized in our pediatric psychiatric hospital for suicidal ideation with intent and plan. The patient had major depressive disorder, anxiety, other specified feeding and eating disorder, and attention-deficit/hyperactive disorder. PMID:28018696

Noonan syndrome is a genetic multisystem disorder characterised by distinctive facial features, developmental delay, learning difficulties, short stature, congenital heart disease, renal anomalies, lymphatic malformations, and bleeding difficulties. Mutations that cause Noonan syndrome alter genes encoding proteins with roles in the RAS–MAPK pathway, leading to pathway dysregulation. Management guidelines have been developed. Several clinically relevant genotype–phenotype correlations aid risk assessment and patient management. Increased understanding of the pathophysiology of the disease could help development of pharmacogenetic treatments. PMID:23312968

Mechanisms and management of the heart in Myotonic Dystrophy

PubMed Central

McNally, Elizabeth M.; Sparano, Dina

2015-01-01

Myotonic dystrophy (DM) is the most common form of adult onset muscular dystrophy and is caused by expansion of short nucleotide repeats that, in turn, produce toxic RNA aggregates within cells. DM is multisystemic, and the heart is primary site of pathology. DM patients exhibit cardiac conduction disorders including atrial fibrillation, atrio-ventricular heart block and ventricular arrhythmias. DM patients are also at risk for cardiomyopathy and congestive heart failure. Myotonic dystrophy is also characterized by myotonia, muscle weakness, and profound fatigue. The management of these symptoms requires input from the cardiologist and a team approach to minimize the debilitating aspects of the disorder and optimize cardiac function. PMID:21642660

Dental treatment for people with cystic fibrosis.

To describe the nature and consequences of the multi-system genetic condition cystic fibrosis with a view to ensuring optimal dental treatment planning for these patients. A literature search was conducted to identify the key medical and dental manifestations of cystic fibrosis. These findings are discussed and utilised to create recommendations for treatment planning in patients with cystic fibrosis for the practising dental practitioner. Cystic fibrosis is a complex, lethal, multisystem autosomal recessive disorder resulting from mutations on chromosome 7 which result in dysfunction of an ion channel that sits on epithelial surfaces. Respiratory disease remains the leading cause of mortality. Survival has greatly increased in recent decades secondary to improved treatment and specialist care. Specific dental manifestations of the disease may result from the condition itself or complications of treatment. Modification of patient management may be necessary to provide optimum patient care. The pathophysiology and clinical manifestations are relevant to practicing dental practitioners and inform recommendations to be utilised to ensure optimal treatment planning for these patients.

Notes from the Field: Community-Based Prevention of Rocky Mountain Spotted Fever - Sonora, Mexico, 2016.

2016-11-25

Rocky Mountain spotted fever (RMSF), a life-threatening tickborne zoonosis caused by Rickettsia rickettsii, is a reemerging disease in Mexico (1,2). R. rickettsii is an intracellular bacterium that infects vascular endothelium and can cause multisystem organ failure and death in the absence of timely administration of a tetracycline-class antibiotic, typically doxycycline. Epidemic RMSF, as described in parts of Arizona and Mexico, is associated with massive local infestations of the brown dog tick (Rhiphicephalus sanguineus sensu lato) on domestic dogs and in peridomestic settings that result in high rates of human exposure; for example, during 2003-2012, in Arizona the incidence of RMSF in the three most highly affected communities was 150 times the U.S. national average (3,4). In 2015, the Mexico Ministry of Health (MOH) declared an epidemiologic emergency because of high and sustained rates of RMSF in several states in northern Mexico, including the state of Sonora. During 2004-2015, a total of 1,129 cases and 188 RMSF deaths were reported from Sonora (Sonora MOH, unpublished data, 2016). During 2009-2015, one impoverished community (community A) in Sonora reported 56 cases of RMSF involving children and adolescents, with a case-fatality rate of 40% (Sonora MOH, unpublished data, 2016). Poverty and lack of timely access to health services are risk factors for severe RMSF. Children are especially vulnerable to infection, because they might have increased contact with dogs and spend more time playing around spaces where ticks survive (5). In Sonora, case fatality rates for children aged <10 years can be as high as 30%, which is almost four times the aggregate case-fatality rate reported for the general population of the state (8%) (2), and 10-13 times higher than the case-fatality rate described for this age group in the United States (2.4%) (6).

Musical Instrument-Associated Health Issues and Their Management.

2017-09-01

Playing musical instruments can bring joy to people, but can also cause a wide variety of health issues that range from mild disorders to potentially fatal conditions. Although sports medicine is an established medical subspecialty, relatively few studies have investigated the health issues associated with musical instruments. Here we present an overview of these health issues. These include infections due to microorganisms, allergic reactions, as well as mechanical injuries from sustained high pressures within the oral, mediastinal, thoracic, and abdominal cavities. For example, wind instruments can potentially harbor thousands of pathogenic organisms. If several players share the same instrument, these instruments present potential hazards in the spread of infections. A fatal case of hypersensitivity pneumonitis in a bagpiper is particularly noteworthy. Similarly, a case of gastrointestinal anthrax in an animal-hide drummer is a reminder of this rare but highly fatal disease. Although not fatal, hearing-related disorders, neuromuscular issues, musculoskeletal problems, and contact dermatitis are also very common among instrumentalists. This review aims to illuminate these under-recognized health issues by highlighting both the common conditions and the rare but fatal cases.

Economic losses and burden of disease by medical conditions in Norway.

We explore the correlation between disease specific estimates of economic losses and the burden of disease. This is based on data for Norway in 2013 from the Global Burden of Disease (GBD) project and the Norwegian Directorate of Health. The diagnostic categories were equivalent to the ICD-10 chapters. Mental disorders topped the list of the costliest conditions in Norway in 2013, and musculoskeletal disorders caused the highest production loss, while neoplasms caused the greatest burden in terms of DALYs. There was a positive and significant association between economic losses and burden of disease. Neoplasms, circulatory diseases, mental and musculoskeletal disorders all contributed to large health care expenditures. Non-fatal conditions with a high prevalence in working populations, like musculoskeletal and mental disorders, caused the largest production loss, while fatal conditions such as neoplasms and circulatory disease did not, since they occur mostly at old age. The magnitude of the production loss varied with the estimation method. The estimations presented in this study did not include reductions in future consumption, by net-recipients, due to premature deaths. Non-fatal diseases are thus even more burdensome, relative to fatal diseases, than the production loss in this study suggests. Hence, ignoring production losses may underestimate the economic losses from chronic diseases in countries with an epidemiological profile similar to Norway. Copyright © 2017 Elsevier B.V.

2000-01-01

To assess the mental disturbances induced by accidents at work, 41 male workers who had witnessed a fatal work accident were evaluated utilizing the criteria for posttraumatic stress disorder (PTSD) from the ICD-10 Classification of Mental and Behavioral Disorders. The Hamilton Depression Rating Scale (HDRS) was also administered to the exposed workers, as well as to 47 non-exposed construction-worker controls. The two groups were well matched with respect to age, years of employment, and years of education. They were all of Han sect; and lifestyles, incomes, and living conditions were similar. The exposed workers had a high rate of PTSD: 11 of 41 (26.8%) at one month and five of 39 (12.9%) four months after the fatal accident. The exposed groups' scores for depressive symptoms were significantly higher than those of the controls, including: 1) depressed mood, 2) guilt, 3) initial insomnia, 4) middle insomnia, 5) delayed insomnia, 6) decreased interest in work and other activities, 7) anxiety, 8) somatization, and 9) gastrointestinal symptoms (p < 0.05, p < 0.01, p < 0.001). Fatal work accidents, a major hazard in the construction industry, affect not only the victims but also the mental health of other workers. PTSD and associated emotional disorders related to exposure to serious work accidents deserve more attention for clinical and research purposes.

Thirty years after the discovery of HIV and 15 years since the advent of Highly Active Antiretroviral Therapy (HAART), the features of HIV infection have evolved and need a new approach, which is both more comprehensive and specialized. Indeed, the burden of a chronic disease with multiple determining features has replaced the rapidly fatal infection of the past, which was almost exclusively related to the effects of immunosuppression. Physicians have to be concerned with "new risks" associated with treatment side effects; the consequences of ongoing inflammation and ageing of the HIV-infected population. These include metabolic, cardiovascular, neurocognitive and renal disease as well as lipodystrophy and malignancy. Antiretroviral treatment has been a major step forward, subject to accessibility, tolerance and adherence, but it has not solved all the problems associated with this infection, as it becomes a chronic illness.

2016-01-01

Acquired hemophilia A (AHA) is a relatively rare and life-threatening bleeding disorder whose pathogenesis is not completely understood. The present study reports a rare case of immunogubulin (IgG)4-related AHA with multisystemic involvement. A 55-year old male patient presented with symptoms of bronchial asthma and multiple subdermal hematomas. Chest computed tomography showed multiple diffuse nodular lesions with thickening of bronchovascular bundles, and scattered high-density spots in both lung lobes. Laboratory investigations showed increased activated partial prothrombin time (120.0 sec), a markedly decreased factor VIII (FVIII) activity (0.5%), a high-titer of FVIII inhibitor (27.2 Bethesda units/ml) and a marked increase in serum IgG4 (>4.03 g/l) level. Left inguinal lymph node biopsy revealed capsular thickening with marked lymphoplasmacytic infiltration, occlusive phlebitis and irregular fibrosis. Immunostaining revealed numerous IgG4-positive plasma cells (>100 cells/human plasma fibronectin) in the nodular lesions, with an IgG4/IgG ratio of >40%. The symptoms were markedly alleviated following corticosteroid therapy. The current study presents the first reported case of a rare IgG4-related AHA that presented with unusual clinical features and multisystemic involvement. The patient responded well to corticosteroid therapy. Documentation of such rare cases will help in characterizing the pathogenesis, and prompt recognition and timely treatment of this rare disorder.

Mitochondrial dysfunctions are known to be responsible for a number of heterogenous clinical presentations with multi-systemic involvement. Impaired oxidative phosphorylation leading to a decrease in cellular energy (ATP) production is the most important cause underlying these disorders. Despite significant progress made in the field of mitochondrial medicine during the last two decades, the molecular mechanisms underlying these disorders are not fully understood. Since the identification of first mitochondrial DNA (mtDNA) mutation in 1988, there has been an exponential rise in the identification of mtDNA and nuclear DNA mutations that are responsible for mitochondrial dysfunction and disease. Genetic complexity together with ever widening clinical spectrum associated with mitochondrial dysfunction poses a major challenge in diagnosis and treatment. Effective therapy has remained elusive till date and is mostly efficient in relieving symptoms. In this review, we discuss the important clinical and genetic features of mitochondrials disorders with special emphasis on diagnosis and treatment. PMID:25857492

Lyme disease and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS): an overview.

PubMed

Rhee, Hanna; Cameron, Daniel J

2012-01-01

Lyme disease (LD) is a complex, multisystemic illness. As the most common vector- borne disease in the United States, LD is caused by bacterial spirochete Borrelia burgdorferi sensu stricto, with potential coinfections from agents of anaplasmosis, babesiosis, and ehrlichiosis. Persistent symptoms and clinical signs reflect multiorgan involvement with episodes of active disease and periods of remission, not sparing the coveted central nervous system. The capability of microorganisms to cause and exacerbate various neuropsychiatric pathology is also seen in pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a recently described disorder attributed to bacterium Streptococcus pyogenes of group A beta-hemolytic streptococcus in which neurologic tics and obsessive-compulsive disorders are sequelae of the infection. In the current overview, LD and PANDAS are juxtaposed through a review of their respective infectious etiologies, clinical presentations, mechanisms of disease development, courses of illness, and treatment options. Future directions related to immunoneuropsychiatry are also discussed.

2015-01-01

Introduction Myotonic dystrophies are inherited multisystemic diseases characterized by musculopathy, cardiac arrythmias and cognitive disorders. These patients are at increased risk for fatal post-surgical complications from pulmonary hypoventilation. We present a case with myotonic dystrophy and esophageal cancer who had a minimally invasive esophagectomy complicated with gastrobronchial fistulisation. Presentation of case A 44-year-old male with myotonic dystrophy type 1 and esophageal cancer had a minimally invasive esophagectomy performed instead of open surgery in order to reduce the risk for pulmonary complications. At day 15 respiratory failure occurred from a gastrobronchial fistula between the right intermediary bronchus (defect 7–8 mm) and the esophagogastric anastomosis (defect 10 mm). In order to minimize large leakage of air into the gastric conduit the anastomosis was stented and ventilation maintained at low airway pressures. His general condition improved and allowed extubation at day 29 and stent removal at day 35. Bronchoscopy confirmed that the fistula was healed. The patient was discharged from hospital at day 37 without further complications. Discussion The fistula was probably caused by bronchial necrosis from thermal injury during close dissection using the Ligasure instrument. Fistula treatment by non-surgical intervention was considered safer than surgery which could be followed by potentially life-threatening respiratory complications. Indications for stenting of gastrobronchial fistulas will be discussed. Conclusions Minimally invasive esophagectomy was performed instead of open surgery in a myotonic dystrophy patient as these patients are particularly vulnerable to respiratory complications. Gastrobronchial fistula, a major complication, was safely treated by stenting and low airway pressure ventilation. PMID:26520033

To examine the associations between a wide range of mental disorders and subsequent onset of stroke. Lifecourse timing of stroke was examined using retrospectively reconstructed data from cross-sectional surveys. Data from the World Mental Health Surveys were accessed. This data was collected from general population surveys over 17 countries of 87,250 adults. The Composite International Diagnostic Interview retrospectively assessed lifetime prevalence and age at onset of DSM-IV mental disorders. A weighted subsample (n=45,288), was used for analysis in the present study. Survival analyses estimated associations between first onset of mental disorders and subsequent stroke onset. Bivariate models showed that 12/16 mental disorders were associated with subsequent stroke onset (ORs ranging from 1.6 to 3.8). However, after adjustment for mental disorder comorbidity and smoking, only significant relationships between depression and stroke (OR 1.3) and alcohol abuse and stroke (OR 1.5) remained. Among females, having a bipolar disorder was also associated with increased stroke incidence (OR 2.1). Increasing number of mental disorders was associated with stroke onset in a dose-response fashion (OR 3.3 for 5+ disorders). Depression and alcohol abuse may have specific associations with incidence of non-fatal stroke. General severity of psychopathology may be a more important predictor of non-fatal stroke onset. Mental health treatment should be considered as part of stroke risk prevention. Limitations of retrospectively gathered cross sectional surveys design mean further research on the links between mental health and stroke incidence is warranted. Copyright © 2015 Elsevier Inc.

The Many Faces of Lupus

PubMed Central

El-Gabalawy, Hani

1990-01-01

Systemic lupus erythematosus is a multisystem disorder that presents itself in several different ways. Arthritis, dermatitis, nephritis, and pleuropericarditis are the most common features initially. Various hematologic and neuropsychiatric manifestations are also seen during the course of the disease. Anti-nuclear antibodies are the hallmark of lupus but are nonspecific and detectable in many other disorders. Once the diagnosis is established, the severity of the disease needs to be determined, in particular the extent of major organ involvement. The level of disease activity should be repeatedly estimated using clinical and laboratory parameters. Therapeutic decisions are based on disease severity and activity. Aggressive suppression of major organ inflammation and reduction of long-term toxicity are the main goals of therapy. PMID:21233973

Canine and feline joint disease can be a primary disorder limited to joints or a manifestation of multisystemic disease. Collection and analysis of joint fluid provides valuable information for the diagnosis, prognosis, and treatment of diseases that affect the joint space. The cytologic recognition of the cellular components and infectious agents in synovial fluid categorizes the cell response and differentiates inflammatory and noninflammatory joint disorders. This information is supported by the cell counts, protein content, mucin clot test, bacterial culture, and serologic tests for infectious or immune-mediated disease. These results are integrated with the clinical history, physical examination, radiographic findings, and ancillary test results to arrive at a diagnosis and treatment plan.

Leprosy is a chronic granulomatous infectious multisystem disease that may present with protean manifestations. It mimics many systemic and dermatological disorders. Here we report a case in which an elderly female presented with malar rash, intermittent fever, and arthralgia. Her diagnosis was significantly delayed due to a close clinical resemblance to systemic lupus erythematosus. It is important to be aware of such manifestations of leprosy and improve awareness of it in clinicians to avoid misdiagnosis and delay in treatment.

Sarcoidosis is a multisystem inflammatory disorder of unknown cause which can affect any organ system. Autosomal dominant lysozyme amyloidosis is a very rare form of hereditary amyloidosis. The Arg64 variant is extraordinarily rare with each family showing a particular pattern of organ involvement, however while Sicca syndrome, gastrointestinal involvement and renal failure are common, lymph node involvement is very rare. In this case report we describe the first reported case of sarcoidosis in association with hereditary lysozyme amyloidosis.

Alkaptonuria is a rare autosomal recessive metabolic disorder that may present with multi-system involvement such as ochronotic arthropathy, renal, urethral and prostatic calculi, cardiac valvular lesions and pigmentation of the skin, sclera, cartilage and other connective tissues. An association of the disease with uveitis has never been reported. We report the first case of alkaptonuria with ochronotic arthropathy presenting with recurrent acute anterior uveitis as the initial manifestation. The possible common link with the HLA-B27 gene is discussed.

Thalassemia and sickle cell disease (SCD) are disorders of hemoglobin that affect millions of people worldwide. The carrier states for these diseases arose as common, balanced polymorphisms during human history because they afforded protection against severe forms of malaria. These complex, multisystem diseases are reviewed here with a focus on current standards of clinical management and recent research findings. The importance of a comprehensive, multidisciplinary and lifelong system of care is also emphasized. PMID:29127677

Ho, Alan Y; Dimitropoulos, Anastasia

2010-05-06

Prader-Willi syndrome (PWS) is a complex neurodevelopmental disorder caused by an abnormality on the long arm of chromosome 15 (q11-q13) that results in a host of phenotypic characteristics, dominated primarily by hyperphagia and insatiable appetite. Characteristic behavioral disturbances in PWS include excessive interest in food, skin picking, difficulty with a change in routine, temper tantrums, obsessive and compulsive behaviors, and mood fluctuations. Individuals with PWS typically have intellectual disabilities (borderline to mild/moderate mental retardation) and exhibit a higher overall behavior disturbance compared to individuals with similar intellectual disability. Due to its multisystem disorder, family members, caregivers, physicians, dieticians, and speech-language pathologists all play an important role in the management and treatment of symptoms in an individual with PWS. This article reviews current research on behavior and cognition in PWS and discusses management guidelines for this disorder.

Inflammatory lesions, like periapical/odontogenic abscesses, are by far the most common pathologic condition of the jaws. Radiographically, these lesions commonly manifest as widening of periodontal ligament space, discontinuity of lamina dura and ill-defined periapical radiolucency. There are some rare disorders which could cause similar radiographic changes in the jaw bone. With careful scrutiny of periapical radiolucency, regular periodic follow-up radiographs and histo-pathologic examination, the periapical abscess or infection can be differentiated from rare fatal disorders. This paper highlights the need for vigilant examination of even the commonest, innocuous-appearing periapical changes which sometimes are produced by some rare fatal disorders.

To determine the rate and risk of suicide and accidental fatal drug overdose (ie, overdose deemed not to have been suicide) in individuals who had been medically ascertained as having been sexually abused during childhood. A historical cohort linkage study of suicide and accidental drug-induced death among victims of child sexual abuse (CSA). Forensic medical records of 2759 victims of CSA who were assessed between 1964 and 1995 were obtained from the Victorian Institute of Forensic Medicine and linked with coronial data representing a follow-up period of up to 44 years. Rates of suicide and accidental fatal drug overdose recorded in coronial databases between 1991 and 2008, and rates of psychiatric disorders and substance use recorded in public mental health databases. Twenty-one cases of fatal self-harm were recorded. Relative risks for suicide and accidental fatal overdose among CSA victims, compared with age-limited national data for the general population, were 18.09 (95% CI, 10.96-29.85; population-attributable risk, 0.37%), and 49.22 (95% CI, 36.11-67.09; population-attributable risk, 0.01%) respectively. Relative risks were higher for female victims. Similar to the general population, CSA victims who died as a result of self-harm were predominantly aged in their 30s at time of death. Most had contact with the public mental health system and half were recorded as being diagnosed with an anxiety disorder. Our data highlight that CSA victims are at increased risk of suicide and accidental fatal drug overdose. CSA is a risk factor that mediates suicide and fatal overdose.

IMPORTANCE Genetic factors contribute to risk for bipolar disorder (BP), yet its pathogenesis remains poorly understood. A focus on measuring multi-system quantitative traits that may be components of BP psychopathology may enable genetic dissection of this complex disorder, and investigation of extended pedigrees from genetically isolated populations may facilitate the detection of specific genetic variants that impact on BP as well as its component phenotypes. OBJECTIVE To identify quantitative neurocognitive, temperament-related, and neuroanatomic phenotypes that appear heritable and associated with severe bipolar disorder (BP-I), and therefore suitable for genetic linkage and association studies aimed at identifying variants contributing to BP-I risk. DESIGN Multi-generational pedigree study in two closely related, genetically isolated populations: the Central Valley of Costa Rica (CVCR) and Antioquia, Colombia (ANT). PARTICIPANTS 738 individuals, all from CVCR and ANT pedigrees, of whom 181 are affected with BP-I. MAIN OUTCOME MEASURE Familial aggregation (heritability) and association with BP-I of 169 quantitative neurocognitive, temperament, magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) phenotypes. RESULTS Seventy-five percent (126) of the phenotypes investigated were significantly heritable, and 31% (53) were associated with BP-I. About 1/4 of the phenotypes, including measures from each phenotype domain, were both heritable and associated with BP-I. Neuroimaging phenotypes, particularly cortical thickness in prefrontal and temporal regions, and volume and microstructural integrity of the corpus callosum, represented the most promising candidate traits for genetic mapping related to BP based on strong heritability and association with disease. Analyses of phenotypic and genetic covariation identified substantial correlations among the traits, at least some of which share a common underlying genetic architecture. CONCLUSIONS AND RELEVANCE This is the most extensive investigation of BP-relevant component phenotypes to date. Our results identify brain and behavioral quantitative traits that appear to be genetically influenced and show a pattern of BP-I-association within families that is consistent with expectations from case-control studies. Together these phenotypes provide a basis for identifying loci contributing to BP-I risk and for genetic dissection of the disorder. PMID:24522887

Abstract Mitochondrial disorders are genetically determined metabolic diseases due to a biochemical deficiency of the respiratory chain. Given that multi-system involvement and disease progression are common features of mitochondrial disorders they carry substantial morbidity and mortality. Despite this, no disease-modifying treatments exist with clear clinical benefits, and the current best management of mitochondrial disease is supportive. Several therapeutic strategies for mitochondrial disorders are now at a mature preclinical stage. Some are making the transition into early-phase patient trials, but the lack of validated biomarkers of disease progression presents a challenge when developing new therapies for patients. This update discusses current biomarkers of mitochondrial disease progression including metabolomics, circulating serum markers, exercise physiology, and both structural and functional imaging. We discuss the advantages and disadvantages of each approach, and consider emerging techniques with a potential role in trials of new therapies. PMID:28969370

Pearson marrow-pancreas syndrome is a fatal disorder mostly diagnosed during infancy and caused by mutations of mitochondrial DNA. We hereby report on four children affected by Pearson syndrome with hematological disorders at onset. The disease was fatal to three of them and the fourth one, who received hematopoietic stem cell transplantation, died of secondary malignancy. In this latter patient transplantation corrected hematological and non-hematological issues like metabolic acidosis, and we therefore argue that it could be considered as a useful option in an early stage of the disease.

Benign hereditary chorea is a rare autosomal dominant disorder presenting with a childhood-onset and slowly progressive chorea. The objective of this study was to describe the clinical and genetic features of 3 patients who developed childhood-onset chorea. Three affected patients from three generations of a family with benign hereditary chorea associated with a multisystemic disorder of the basal ganglia, thyroid, lungs, salivary glands, bowels, and teeth. The TITF-1 gene was screened by microsatellite analysis, gene sequencing, and fluorescence in situ hybridization. Genetic analysis revealed a novel 0.9-Mb deletion on chromosome 14, which includes the TITF-1 and PAX9 genes. We have identified a novel deletion responsible for a new syndrome of benign hereditary chorea, including symptoms of brain-thyroid-lung syndrome associated with bowels, salivary glands, and teeth disorders. Associated signs, sometimes of slight expression, remain of high interest for the clinical and genetic diagnosis of benign hereditary chorea. Copyright 2006 Movement Disorder Society.

Lyme disease and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS): an overview

PubMed Central

Rhee, Hanna; Cameron, Daniel J

2012-01-01

Lyme disease (LD) is a complex, multisystemic illness. As the most common vector- borne disease in the United States, LD is caused by bacterial spirochete Borrelia burgdorferi sensu stricto, with potential coinfections from agents of anaplasmosis, babesiosis, and ehrlichiosis. Persistent symptoms and clinical signs reflect multiorgan involvement with episodes of active disease and periods of remission, not sparing the coveted central nervous system. The capability of microorganisms to cause and exacerbate various neuropsychiatric pathology is also seen in pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), a recently described disorder attributed to bacterium Streptococcus pyogenes of group A beta-hemolytic streptococcus in which neurologic tics and obsessive-compulsive disorders are sequelae of the infection. In the current overview, LD and PANDAS are juxtaposed through a review of their respective infectious etiologies, clinical presentations, mechanisms of disease development, courses of illness, and treatment options. Future directions related to immunoneuropsychiatry are also discussed. PMID:22393303

Hypothyroidism associated with parathyroid disorders.

PubMed

Mantovani, Giovanna; Elli, Francesca Marta; Corbetta, Sabrina

2017-03-01

Hypothyroidism may occur in association with congenital parathyroid disorders determining parathyroid hormone insufficiency, which is characterized by hypocalcemia and concomitant inappropriately low secretion of parathormone (PTH). The association is often due to loss of function of genes common to thyroid and parathyroid glands embryonic development. Hypothyroidism associated with hypoparathyroidism is generally mild and not associated with goiter; moreover, it is usually part of a multisystemic involvement not restricted to endocrine function as occurs in patients with 22q11 microdeletion/DiGeorge syndrome, the most frequent disorders. Hypothyroidism and hypoparathyroidism may also follow endocrine glands' damages due to autoimmunity or chronic iron overload in thalassemic disorders, both genetically determined conditions. Finally, besides PTH deficiency, hypocalcemia can be due to PTH resistance in pseudohypoparathyroidism; when hormone resistance is generalized, patients can suffer from hypothyroidism due to TSH resistance. In evaluating patients with hypothyroidism and hypocalcemia, physical examination and clinical history are essential to drive the diagnostic process, while routine genetic screening is not recommended.

Mitochondrial diseases, a group of multi-systemic disorders often characterized by tissue-specific phenotypes, are usually progressive and fatal disorders resulting from defects in oxidative phosphorylation. MTO1 (Mitochondrial tRNA Translation Optimization 1), an evolutionarily conserved protein expressed in high-energy demand tissues has been linked to human early-onset combined oxidative phosphorylation deficiency associated with hypertrophic cardiomyopathy, often referred to as combined oxidative phosphorylation deficiency-10 (COXPD10). Thirty five cases of MTO1 deficiency were identified and reviewed through international collaboration. The cases of two female siblings, who presented at 1 and 2years of life with seizures, global developmental delay, hypotonia, elevated lactate and complex I and IV deficiency on muscle biopsy but without cardiomyopathy, are presented in detail. For the description of phenotypic features, the denominator varies as the literature was insufficient to allow for complete ascertainment of all data for the 35 cases. An extensive review of all known MTO1 deficiency cases revealed the most common features at presentation to be lactic acidosis (LA) (21/34; 62% cases) and hypertrophic cardiomyopathy (15/34; 44% cases). Eventually lactic acidosis and hypertrophic cardiomyopathy are described in 35/35 (100%) and 27/34 (79%) of patients with MTO1 deficiency, respectively; with global developmental delay/intellectual disability present in 28/29 (97%), feeding difficulties in 17/35 (49%), failure to thrive in 12/35 (34%), seizures in 12/35 (34%), optic atrophy in 11/21 (52%) and ataxia in 7/34 (21%). There are 19 different pathogenic MTO1 variants identified in these 35 cases: one splice-site, 3 frameshift and 15 missense variants. None have bi-allelic variants that completely inactivate MTO1; however, patients where one variant is truncating (i.e. frameshift) while the second one is a missense appear to have a more severe, even fatal, phenotype. These data suggest that complete loss of MTO1 is not viable. A ketogenic diet may have exerted a favourable effect on seizures in 2/5 patients. MTO1 deficiency is lethal in some but not all cases, and a genotype-phenotype relation is suggested. Aside from lactic acidosis and cardiomyopathy, developmental delay and other phenotypic features affecting multiple organ systems are often present in these patients, suggesting a broader spectrum than hitherto reported. The diagnosis should be suspected on clinical features and the presence of markers of mitochondrial dysfunction in body fluids, especially low residual complex I, III and IV activity in muscle. Molecular confirmation is required and targeted genomic testing may be the most efficient approach. Although subjective clinical improvement was observed in a small number of patients on therapies such as ketogenic diet and dichloroacetate, no evidence-based effective therapy exists.

Homozygous mutations in the aromatic l-amino acid decarboxylase (AADC) gene result in a severe depletion of its namesake protein, triggering a debilitating and often fatal form of infantile Parkinsonism known as AADC deficiency. AADC deficient patients fail to produce normal levels of the monoamine neurotransmitters dopamine and serotonin, and suffer a multi-systemic disorder characterized by movement abnormalities, developmental delay and autonomic dysfunction; an absolute loss of dopamine is generally considered incompatible with life. There is no optimal treatment for AADC deficiency and few truly good models in which to investigate disease mechanisms or develop and refine therapeutic strategies. In this study, we introduced a relatively frequently reported but mildly pathogenic S250F missense mutation into the murine Aadc gene. We show that mutants homozygous for the mutation are viable and express a stable but minimally active form of the AADC protein. Although the low enzymatic activity of the protein resulted in only modestly reduced concentrations of brain dopamine, serotonin levels were markedly diminished, and this perturbed behavior as well as autonomic function in mutant mice. Still, we found no evidence of morphologic abnormalities of the dopaminergic cells in mutant brains. The striatum as well as substantia nigra appeared normal and no loss of dopamine expressing cells in the latter was detected. We conclude that even minute levels of active AADC are sufficient to allow for substantial amounts of dopamine to be produced in model mice harboring the S250F mutation. Such mutants represent a novel, mild model of human AADC deficiency. © The Author 2017. Published by Oxford University Press. All rights reserved.

Gorlin syndrome (GS) is a rare inherited multisystem disorder with predisposition to basal cell carcinomas and various other neoplasms. Characteristic features include falx calcification, multiple odontogenic keratocysts (OKCs), early onset medulloblastoma, craniofacial and skeletal malformations, cardiac and ovarian fibroma. We present a case of GS in a 9-year-old girl with recurrent dental infections which was overlooked for 8 years. Diagnosis was finally suggested by the incidental detection of multiple OKCs and ovarian fibromas on follow-up magnetic resonance imaging performed for surveillance of previous operated brain tumor.

Timely and accurate assessments of disease burden are essential for developing effective national health policies. We used the Global Burden of Disease Study 2015 to examine burden due to mental and substance use disorders in Australia. For each of the 20 mental and substance use disorders included in Global Burden of Disease Study 2015, systematic reviews of epidemiological data were conducted, and data modelled using a Bayesian meta-regression tool to produce prevalence estimates by age, sex, geography and year. Prevalence for each disorder was then combined with a disorder-specific disability weight to give years lived with disability, as a measure of non-fatal burden. Fatal burden was measured as years of life lost due to premature mortality which were calculated by combining the number of deaths due to a disorder with the life expectancy remaining at the time of death. Disability-adjusted life years were calculated by summing years lived with disability and years of life lost to give a measure of total burden. Uncertainty was calculated around all burden estimates. Mental and substance use disorders were the leading cause of non-fatal burden in Australia in 2015, explaining 24.3% of total years lived with disability, and were the second leading cause of total burden, accounting for 14.6% of total disability-adjusted life years. There was no significant change in the age-standardised disability-adjusted life year rates for mental and substance use disorders from 1990 to 2015. Global Burden of Disease Study 2015 found that mental and substance use disorders were leading contributors to disease burden in Australia. Despite several decades of national reform, the burden of mental and substance use disorders remained largely unchanged between 1990 and 2015. To reduce this burden, effective population-level preventions strategies are required in addition to effective interventions of sufficient duration and coverage.

Congenital syphilis (CS) is a multisystemic infection of the newborn (NB) which can produce severe symptoms, and in some cases, even be fatal. In recent years, the incidence of syphilis has increased worldwide and similarly, the cases of CS in neonates have increased. To report two cases of early and severe presentation of CS, focusing on the importance of prevention of vertical transmission and monitoring of treated mothers. The diagnostic difficulties are discussed. Two premature newborns that were diagnosed with probable CS present in the newborn period are presented. In the first case, due to a high index of suspicion, but without confirmatory testing, treatment was started with good clinical response. In the second case, CS was confirmed through positive serology and the specific treatment was given. CS has significant diagnostic challenges as there is no test for early confirmation, therefore, a high index of suspicion might be key in the treatment and consequent prognosis. Due to the current epidemiology of the condition, it is also important to focus on preventive measures.

Martínez-Medina, Miguel Ángel; Rascón-Alcantar, Adela

Rocky Mountain spotted fever is a life threatening disease caused by Rickettsia rickettsia, characterized by multisystem involvement. We studied 19 dead children with Rocky Mountain spotted fever. All children who were suspected of having rickettsial infections were defined as having Rocky Mountain spotted fever by serology test and clinical features. Through the analysis of each case, we identified the clinical profile and complications associated to the death of a patient. In nine (69.2%) of 13 cases that died in the first three days of admission, the associated condition was septic shock. Others complications included respiratory distress causes by non-cardiogenic pulmonary edema, renal impairment, and multiple organ damage. The main cause of death in this study was septic shock. The fatality rate from Rocky Mountain spotted fever can be related to the severity of the infection, delay in diagnosis, and delay in initiation of antibiotic therapy. Pulmonary edema and cerebral edema can be usually precipitated by administration of excess intravenous fluids.

Brief report: Lymphocytic choriomeningitis virus transmitted through solid organ transplantation--Massachusetts, 2008.

PubMed

2008-07-25

Lymphocytic choriomeningitis virus (LCMV) is a rodent-borne arenavirus found worldwide. House mice (Mus musculus) are the natural reservoir, but LCMV also can infect other wild, pet, and laboratory rodents (e.g., rats, mice, guinea pigs, and hamsters). Humans can be infected through exposure to rodent excreta. Person-to-person transmission has occurred only through maternal-fetal transmission and solid organ transplantation. LCMV infection in humans can be asymptomatic or cause a spectrum of illness ranging from isolated fever to meningitis and encephalitis. Overall case fatality is <1%. Fetal infections can result in congenital abnormalities or death. Immunosuppressed patients, such as organ transplant recipients, can develop fatal hemorrhagic fever-like disease. Transmission of LCMV and an LCMV-like arenavirus via organ transplantation has been documented in three previous clusters. Of 11 recipients described in those clusters, 10 died of multisystem organ failure, with LCMV-associated hepatitis as a prominent feature. The surviving patient was treated with ribavirin (an antiviral with in vitro activity against LCMV) and reduction of immunosuppressive therapy. On April 15, 2008, an organ procurement organization (OPO) notified CDC of severe illness in two kidney transplant recipients from a common donor; at the time of notification, one of the recipients had died. Samples from the donor and both recipients were tested at CDC; on April 22, test results revealed evidence of acute LCMV infection in the donor and both recipients. This report summarizes the results of the subsequent public health investigation.

Introduction. Gorlin-Goltz syndrome is an inherited autosomal dominant disorder with complete penetrance and extreme variable expressivity. Case Report. The present paper highlights the importance of diagnostic criteria and histopathology in early and prompt diagnosis which will lead to proper treatment and genetic counseling of the patient. Discussion. Gorlin-Goltz syndrome is about multisystem process comprising the triad of basal cell nevi, jaw keratocysts, and skeletal anomalies. A spectrum of other neurological, ophthalmic, endocrine and genital manifestations is known to be variably associated with this triad. Diagnosis of the syndrome is based on major and minor criteria. Conclusion. This paper emphasizes the importance of oral and maxillofacial health professionals in the early diagnosis of nevoid basal cell carcinoma syndrome and in a preventive multidisciplinary approach to provide a better prognosis to the patient.

Neurofibromatosis type 1 (NF-1) is an autosomal dominant, multisystem disorder, affecting approximately 1 of 3500 people. Ocular disorders, such as Lisch nodules, optic gliomas, and anterior segment defects, are typical with clinical presentation. Anophthalmia, as a rare eye malformation, has never been reported in patients with NF-1. We report a 27-year-old patient in whom clinical manifestations of café au lait spots, neurofibromas, osseous orbital dysplasia, and anophthalmia were observed. The diagnosis of NF-1 was made, according to clinical course and brain computed tomography and magnetic resonance imaging. Because the patient refused aggressive management approaches, she was managed conservatively and is well on follow-up. We suggest that patients presenting with anophthalmia need serious evaluation and that NF-1 needs to be considered in the differential diagnosis.

MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis, stroke-like episodes) is a rare, multisystem disorder which belongs to a group of mitochondrial metabolic diseases. As other diseases in this group, it is inherited in the maternal line. In this report, we discussed a case of a 10-year-old girl with clinical and radiological picture of MELAS syndrome. We would like to describe characteristic radiological features of MELAS syndrome in CT, MRI and MR spectroscopy of the brain and differential diagnosis. The rarity of this disorder and the complexity of its clinical presentation make MELAS patients among the most difficult to diagnose. Brain imaging studies require a wide differential diagnosis, primarily to distinguish between MELAS and ischemic stroke. Particularly helpful are the MRI and MR spectroscopy techniques.

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

In the last three decades there has been ample research to demonstrate that instituting Multisystemic Therapy for serious juvenile offenders, keeping them in the community with intensive intervention, can significantly reduce recidivism. When there is recidivism, it is less severe than in released incarcerated juveniles. Multisystemic Therapy provides 24 h available parental guidance, family therapy, individual therapy, group therapy, educational support and quite importantly a change of peer group. In New York City, there is the new mandate through the Juvenile Justice Initiative to implement interventions to keep juvenile offenders in the community rather than sending them to be incarcerated. However, this paper aims to examine how teaching prosocial values in early childhood can reduce the incidence of first-time juvenile delinquency. Programs such as the Perry School Project will be discussed to demonstrate that although somewhat expensive, these innovative programs nonetheless are quite cost-effective as the cost to society of adjudication, incarceration and victim damages are significantly greater. Along with teaching prosocial 0020 values, there has been renewed interest in early identification of youth at risk for developing Antisocial Personality Disorder. An update is given on the status of both promising approaches in early intervention to prevent serious juvenile delinquency and hence adult criminality.

Ehlers–Danlos Syndrome—Hypermobility Type: A Much Neglected Multisystemic Disorder

Ehlers–Danlos syndrome (EDS)—hypermobility type (HT) is considered to be the most common subtype of EDS and the least severe one; EDS-HT is considered to be identical to the joint hypermobility syndrome and manifests with musculoskeletal complaints, joint instability, and soft tissue overuse injury. Musculoskeletal complaints manifest with joint pain of non-inflammatory origin and/or spinal pain. Joint instability leads to dislocation or subluxation and involves peripheral joints as well as central joints, including the temporomandibular joints, sacroiliac joints, and hip joints. Soft tissue overuse injury may lead to tendonitis and bursitis without joint inflammation in most cases. Ehlers–Danlos syndrome-HT carries a high potential for disability due to recurrent dislocations and subluxations and chronic pain. Throughout the years, extra-articular manifestations have been described, including cardiovascular, autonomic nervous system, gastrointestinal, hematologic, ocular, gynecologic, neurologic, and psychiatric manifestations, emphasizing the multisystemic nature of EDS-HT. Unfortunately, EDS-HT is under-recognized and inadequately managed, leading to neglect of these patients, which may lead to severe disability that almost certainly could have been avoided. In this review article we will describe the known manifestations of the extra-articular systems. PMID:27824552

Neuroimaging to Investigate Multisystem Involvement and Provide Biomarkers in Amyotrophic Lateral Sclerosis

Neuroimaging allows investigating the extent of neurological systems degeneration in amyotrophic lateral sclerosis (ALS). Advanced MRI methods can detect changes related to the degeneration of upper motor neurons but have also demonstrated the participation of other systems such as the sensory system or basal ganglia, demonstrating in vivo that ALS is a multisystem disorder. Structural and functional imaging also allows studying dysfunction of brain areas associated with cognitive signs. From a biomarker perspective, numerous studies using diffusion tensor imaging showed a decrease of fractional anisotropy in the intracranial portion of the corticospinal tract but its diagnostic value at the individual level remains limited. A multiparametric approach will be required to use MRI in the diagnostic workup of ALS. A promising avenue is the new methodological developments of spinal cord imaging that has the advantage to investigate the two motor system components that are involved in ALS, that is, the lower and upper motor neuron. For all neuroimaging modalities, due to the intrinsic heterogeneity of ALS, larger pooled banks of images with standardized image acquisition and analysis procedures are needed. In this paper, we will review the main findings obtained with MRI, PET, SPECT, and nuclear magnetic resonance spectroscopy in ALS. PMID:24949452

Objective Autopsy studies show widespread pathology in amyotrophic lateral sclerosis (ALS), but clinical surveys of multisystem disease in ALS are rare. We investigated ALS-Plus syndrome, an understudied group of patients with clinical features extending beyond pyramidal and neuromuscular systems with or without cognitive/behavioral deficits. Methods In a large, consecutively-ascertained cohort of 550 patients with ALS, we documented atypical clinical manifestations. Genetic screening for C9orf72 hexanucleotide expansions was performed in 343 patients, and SOD1, TARDBP, and VCP were tested in the subgroup of patients with a family history of ALS. Gray matter and white matter imaging was available in a subgroup of 30 patients. Results Seventy-five (13.6%) patients were identified with ALS-Plus syndrome. We found disorders of ocular motility, cerebellar, extrapyramidal and autonomic functioning. Relative to those without ALS-Plus, cognitive impairment (8.0% vs 2.9%, p=0.029), bulbar-onset (49.3% vs 23.2%, p<0.001), and pathogenic mutations (20.0% vs 8.4%, p=0.015) were more than twice as common in ALS-Plus. Survival was significantly shorter in ALS-Plus (29.66 months vs 42.50 months, p=0.02), regardless of bulbar-onset or mutation status. Imaging revealed significantly greater cerebellar and cerebral disease in ALS-Plus compared to those without ALS-Plus. Conclusions ALS-Plus syndrome is not uncommon, and the presence of these atypical features is consistent with neuropathological observations that ALS is a multisystem disorder. ALS-Plus syndrome is associated with increased risk for poor survival and the presence of a pathogenic mutation. PMID:25086858

Patients at various stages of human immunodeficiency virus (HIV) infection require rehabilitation services. These patients present problems for each of the disciplines in a rehabilitation team, and all team members must confront the psychosocial and ethical issues involved with the disease. Patients with HIV infection may have polyneuropathy with multisystem involvement, including dysphagia, autonomic dysfunction, respiratory failure, bowel and bladder dysfunction, generalized weakness, a painful sensory neuropathy, and depression. Guidelines are presented for determining if inpatient rehabilitation or other settings are appropriate. Case management is a valuable strategy for the rehabilitation of patients with this complicated disorder. PMID:1866948

Both acute and chronic spinal cord disorders present multisystem management problems to the clinician. This article highlights key issues associated with chronic spinal cord dysfunction. Advances in symptomatic management for chronic spinal cord dysfunction include use of botulinum toxin to manage detrusor hyperreflexia, pregabalin for management of neuropathic pain, and intensive locomotor training for improved walking ability in incomplete spinal cord injuries. The care of spinal cord dysfunction has advanced significantly over the past 2 decades. Management and treatment of neurologic and non-neurologic complications of chronic myelopathies ensure that each patient will be able to maximize their functional independence and quality of life.

Understanding patterns of medical comorbidity in attention-deficit/hyperactivity disorder (ADHD) may lead to better treatment of affected individuals as well as aid in etiologic study of disease. This article provides the first systematic evaluation on the medical comorbidity of ADHD in a nationally representative sample (National Comorbidity Replication Survey-Adolescent Supplement; N = 6483) using formal diagnostic criteria. Survey-weighted odds ratios adjusted for demographics, additional medical, and mental disorders were calculated for associations between ADHD and medical conditions. Models adjusted for demographics revealed significantly increased odds of allergy, asthma, enuresis, headache/migraine, and serious stomach or bowel problems. After adjusting for comorbidity, across the medical conditions, enuresis and serious stomach problems were the strongest correlates of ADHD. These findings confirm the pervasive medical comorbidity of ADHD reported in previous clinical and community-based studies. The intriguing salience of enuresis and serious stomach or bowel conditions may also provide an important clue to multisystem involvement in ADHD. © The Author(s) 2016.

Perioperative management of the severely obese patient: a selective pathophysiological review.

PubMed

Cullen, Aidan; Ferguson, Andrew

2012-10-01

Obesity is widespread, yet it is often understood primarily as a disorder of body structure. This article provides anesthesiologists with a synopsis of recent research into the complex pathophysiology of obesity. It emphasizes the importance of this information for the perioperative planning and management of this patient group and for reviewing some of the major perioperative challenges. Obesity is a multisystem chronic pro-inflammatory disorder associated with increased morbidity and mortality. Adipocytes are far more than storage vessels for lipids. They secrete a large number of physiologically active substances called adipokines that lead to inflammation, vascular and cardiac remodelling, airway inflammation, and altered microvascular flow patterns. They contribute to linked abnormalities, such as insulin resistance and the metabolic syndrome, and they attract and activate inflammatory cells such as macrophages. These changes can lead ultimately to organ dysfunction, especially cardiovascular and pulmonary issues. In the respiratory system, anesthesiologists should be familiar not just with screening tools for obstructive sleep apnea but also with obesity hypoventilation syndrome, which is less well appreciated and carries a significant outcome disadvantage. Perioperative management is challenging. It is centred around cardiorespiratory and metabolic optimization, minimizing adverse effects of both pain and systemic opioids, effective use of regional anesthesia, and an emphasis on mobilization and nutrition - given the prevalence of micronutrient deficiencies in the severely obese. There is a risk of incorrect drug dosing in obesity, which requires an understanding of the appropriate dosing weights for perioperative medications. The literature clearly highlights the complexity of severe obesity as a multisystem disease, and anesthesiologists caring for these patients perioperatively must have a sound understanding of the changes in order to offer the highest quality care to these patients.

Objectives Outcomes of atrial fibrillation (AF) in patients with severe mental disorders are largely unknown. We compared rates of stroke, fatal thromboembolic events and bleeding in patients with AF with and without mental disorders. Design Nationwide registry-based cohort study. Setting Denmark (population 5.6 million), 2000–2015. Participants Patients with AF with schizophrenia (n=534), severe depression (n=400) or bipolar disease (n=569) matched 1:5 on age, sex and calendar time to patients with AF without mental disorders. Exposure Inpatient or hospital-based outpatient diagnosis of schizophrenia, severe depression or bipolar disease. Primary and secondary outcome measures HRs for stroke, fatal thromboembolic events and major bleeding comparing patients with and without mental disorders estimated by Cox regression with sequential adjustment for risk factors for stroke and bleeding, comorbidity and initiation of oral anticoagulant therapy (OAT). Results Compared with matched comparisons, crude 5-year HRs of ischaemic stroke were 1.37 (95% CI 0.88 to 2.14) for schizophrenia, 1.36 (95% CI 0.89 to 2.08) for depression and 1.04 (95% CI 0.69 to 1.56) for bipolar disease. After adjusting for risk factors, comorbidity and OAT, these HRs declined towards the null. Crude HRs of fatal thromboembolic events were 3.16 (95% CI 1.78 to 5.61) for schizophrenia, 1.31 (95% CI 0.67 to 2.56) for depression and 1.53 (95% CI 0.93 to 2.53) for bipolar disease. Rates of major bleeding were increased in patients with schizophrenia (crude HR 1.37, 95% CI 0.99 to 1.90) and severe depression (HR 1.25, 95% CI 0.87 to 1.78) but not bipolar disease (HR 0.82, 95% CI 0.58 to 1.15). Conclusion Patients with AF with schizophrenia or severe depression experienced increased rates of stroke and major bleeding compared with matched comparisons. This increase was largely explained by differences in the prevalence of risk factors for stroke and bleeding, comorbidity and initiation of OAT during follow-up. Patients with AF with schizophrenia further experienced higher mortality following thromboembolic events than matched comparisons without mental disorders. PMID:29217725

The safety of cough and cold medication (CCM) use in children has been questioned. We describe the safety profile of CCMs in children <12 years of age from a multisystem surveillance program. Cases with adverse events (AEs) after ingestion of at least 1 index CCM ingredient (brompheniramine, chlorpheniramine, dextromethorphan, diphenhydramine, doxylamine, guaifenesin, phenylephrine, and pseudoephedrine) in children <12 years of age were collected from 5 data sources. An expert panel determined relatedness, dose, intent, and risk factors. Case characteristics and AEs are described. Of the 4202 cases reviewed, 3251 (77.4%) were determined to be at least potentially related to a CCM, with accidental unsupervised ingestions (67.1%) and medication errors (13.0%) the most common exposure types. Liquid (67.3%), pediatric (75.5%), and single-ingredient (77.5%) formulations were most commonly involved. AEs occurring in >20% of all cases included tachycardia, somnolence, hallucinations, ataxia, mydriasis, and agitation. Twenty cases (0.6%) resulted in death; most were in children <2 years of age (70.0%) and none involved a therapeutic dose. The overall reported AE rate was 0.573 cases per 1 million units (ie, tablets, gelatin capsules, or liquid equivalent) sold (95% confidence interval, 0.553-0.593) or 1 case per 1.75 million units. The rate of AEs associated with CCMs in children was low. Fatalities occurred even less frequently. No fatality involved a therapeutic dose. Accidental unsupervised ingestions were the most common exposure types and single-ingredient, pediatric liquid formulations were the most commonly reported products. These characteristics present an opportunity for targeted prevention efforts. Copyright © 2017 by the American Academy of Pediatrics.

A female newborn presented with a congenital urticarial rash that consisted of fluctuating well-demarcated pink or pale reddish macules or slightly raised papules and plaques. In addition, purulent cerebrospinal fluid was present in the absence of evidence of congenital infection. Skin biopsy revealed a sparse infiltrate throughout the entire dermis, including the eccrine adventitia. The infiltrate was composed mostly of neutrophils, but rarely lymphocytes and eosinophils could also be seen. No vasculitis was present. Because of the presenting attributes, a diagnosis of cryopyrin-associated periodic syndrome (CAPS) was considered and the neonatal-onset multisystem inflammatory disorder (NOMID) that represents the most severe expression of the CAPS clinical spectrum was favored. Diagnosis was confirmed by identification of a mutation in the cold-induced autoinflammatory syndrome-1 gene and by an observed response to treatment with the interleukin-1 receptor antagonist anakinra. Both the clinical and histopathological findings of the presented case may represent a distinct entity within the spectrum of aseptic neutrophilic dermatitis. We refer to this spectrum as neutrophilic urticarial dermatosis (NUD), which may serve as a cutaneous marker of autoinflammation. NUD with perieccrine involvement should prompt consideration of CAPS, especially NOMID, in the context of neonatal multisystem disease. Copyright © 2010 John Wiley & Sons A/S.

Suicide is a major public health concern and a leading cause of death in the United States. Psychopathology is an established risk factor for non-fatal suicidal behavior; however, it is unclear whether premenstrual dysphoric disorder (PMDD), a psychiatric disorder specific to women, is correlated with these outcomes. The objective of this study was to determine if PMDD status was associated with suicidal ideation, plans, and attempts, independent of socio-demographic factors and psychiatric comorbidity. We conducted a secondary data analysis of 3,965 American women aged 18-40 who participated in the Collaborative Psychiatric Epidemiology Survey. Descriptive statistics and forward stepwise logistic regression modeling were performed using SUDAAN software. The prevalence of non-fatal suicidal behaviors increased in a graded fashion according to PMDD status. Although the control for demographic characteristics and psychiatric comorbidity greatly attenuated the unadjusted association between PMDD and suicidal behaviors, women with PMDD remained significantly more likely than women with no premenstrual symptoms to report suicidal ideation (OR 2.22; 95% CI 1.40-3.53), plans (OR 2.27; 95% CI 1.20-4.28), and attempts (OR 2.10; 95% CI 1.08-4.08). Only the likelihood of suicidal ideation was significantly elevated among women with moderate/severe premenstrual syndrome (PMS; OR 1.49; 95% CI 1.17-1.88), compared to women with no premenstrual symptoms. PMDD was strongly and independently associated with non-fatal suicidal behaviors among a nationally representative sample. These findings suggest that clinicians treating women with PMDD should assess and be vigilant for signs of non-fatal suicidal behavior, and that clinicians should evaluate and treat the premenstrual symptoms of women who express these behaviors.

"What an Affliction": Mary Todd Lincoln's Fatal Pernicious Anemia.

PubMed

Sotos, John G

2015-01-01

To date, no single diagnosis has unified the psychiatric illness and the numerous poorly defined physical complaints that Mary Lincoln (née Todd, 1818-1882) suffered in adulthood. Here, I show that her physical ailments spanned 30 years and included sore mouth, pallor, paresthesias, the Lhermitte symptom, fever, headaches, fatigue, resting tachycardia, edema, episodic weight loss, progressive weakness, ataxia, and visual impairment. Long thought hypochondriacal, these findings, plus their time course and her psychopathology (irritability, delusions, hallucinations, with preserved clarity), are all consistent with vitamin B12 deficiency. Pernicious anemia most probably caused this deficiency: she lacked risk factors for other causes, and her consanguineous parents both derived from a region of Scotland having a high incidence of pernicious anemia. A diagnosis of chronic multisystem pernicious anemia would clarify the conduct of Mary Lincoln as First Lady and widow, and illuminate challenges faced by her husband, President Abraham Lincoln. Her case highlights many forgotten features of the natural history of untreated pernicious anemia and is unique in the medical literature in demonstrating such a course extending over a lifetime.

Primary cilia are unique sensory organelles that coordinate cellular signaling networks in vertebrates. Inevitably, defects in the formation or function of primary cilia lead to imbalanced regulation of cellular processes that causes multisystemic disorders and diseases, commonly known as ciliopathies. Mounting evidence has demonstrated that primary cilia coordinate multiple activities that are required for cell migration, which, when they are aberrantly regulated, lead to defects in organogenesis and tissue repair, as well as metastasis of tumors. Here, we present an overview on how primary cilia may contribute to the regulation of the cellular signaling pathways that control cyclic processes in directional cell migration. PMID:26955067

Myotonic dystrophy (Dystrophia Myotonica, DM) is the most frequently inherited neuromuscular disease of adult life. It is a multisystemic disease with major cardiac involvement. Core features of myotonic dystrophy are myotonia, muscle weakness, cataract, respiratory failure and cardiac conduction abnormalities. Classical DM, first described by Steinert and called Steinert's disease or DM1 (Dystrophia Myotonica type 1) has been identified as an autosomal dominant disorder associated with the presence of an abnormal expansion of a CTG trinucleotide repeat in the 3' untranslated region of DMPK gene on chromosome 19. This review will mainly focus on the various aspects of cardiac involvement in DM1 patients and the current role of cardiac pacing in their treatment. PMID:23097601

The purpose of this article is to review the current literature on Vogt-Koyanagi-Harada (VKH) disease, including current treatment options and new research directions. Recent publications on VKH disease show an increased focus on the immunogenetics and immune pathways associated with the development of VKH disease. There have also been advances in imaging modalities and techniques that may help to better elucidate the disease process in eyes with VKH disease. VKH disease is an autoimmune, multisystem inflammatory disorder, the cause of which is still incompletely understood. Continued research may elucidate the causes and triggers of immune dysregulation in this disease, and in doing so, identify novel therapeutic targets.

Sarcoidosis is a chronic multisystem disorder characterized by an accumulation of T lymphocytes and mononuclear phagocytes, non-caseating epitheliod granulomas and derangement of normal tissue architecture in affected organs. Sarcoidosis can affect any organ system, however approximately 90% of patients with sarcoidosis have pulmonary, lymph node, cutaneous or ocular manifestations. Renal involvement in sarcoidosis is rare and clinically significant renal dysfunction even less common. We present a case of isolated renal sarcoidosis which manifested with progressively worsening renal function and hypercalcemia. A systematic diagnostic approach with pertinent laboratory studies, imaging and renal biopsy elucidated the diagnosis of renal sarcoidosis without any evidence of systemic involvement.

Recent advances in understanding amyotrophic lateral sclerosis (ALS) have delivered new questions. Disappointingly, the initial enthusiasm for transgenic mouse models of the disease has not been followed by rapid advances in therapy or prevention. Monogenic models may have inadvertently masked the true complexity of the human disease. ALS has evolved into a multisystem disorder, involving a final common pathway accessible via multiple upstream aetiological tributaries. Nonetheless, there is a common clinical core to ALS, as clear today as it was to Charcot and others. We stress the continuing relevance of clinical observations amid the increasing molecular complexity of ALS. PMID:25644224

Lysosomal storage diseases are inherited metabolic disorders caused by genetic defects causing deficiency of various lysosomal proteins, and resultant accumulation of non-degraded compounds. They are multisystemic diseases, and in most of them (>70%) severe brain dysfunctions are evident. However, expression of various phenotypes in particular diseases is extremely variable, from non-neuronopathic to severely neurodegenerative in the deficiency of the same enzyme. Although all lysosomal storage diseases are monogenic, clear genotype-phenotype correlations occur only in some cases. In this article, we present an overview on various factors and processes, both general and specific for certain disorders, that can significantly modulate expression of phenotypes in these diseases. On the basis of recent reports describing studies on both animal models and clinical data, we propose a hypothesis that efficiency of production of compounds that cannot be degraded due to enzyme deficiency might be especially important in modulation of phenotypes of patients suffering from lysosomal storage diseases.

Unraveling the Pathogenesis of Hoyeraal-Hreidarsson Syndrome, a Complex Telomere Biology Disorder

SUMMARY Hoyeraal-Hreidarsson (HH) syndrome is a multisystem genetic disorder characterized by very short telomeres and considered a clinically severe variant of dyskeratosis congenita (DC). The main cause of mortality, usually in early childhood, is bone marrow failure. Mutations in several telomere biology genes have been reported to cause HH in about 60% of the HH patients, but the genetic defects in the rest of the patients are still unknown. Understanding the aetiology of HH and its diverse manifestations is challenging because of the complexity of telomere biology and the multiple telomeric and non-telomeric functions played by telomere-associated proteins in processes such as telomere replication, telomere protection, DNA damage response and ribosome and spliceosome assembly. Here we review the known clinical complications, molecular defects and germline mutations associated with HH, and elucidate possible mechanistic explanations and remaining questions in our understanding of the disease.

Malignant hyperthermia is a main cause of death during general anesthesia, particularly in children. However, research has been hampered by the lack of a convenient animal model, the only one available being a special strain of pig. In this study, we describe spontaneous myopathy and a fatal syndrome of generalized muscle rigidity triggered by halothane in an outbred strain of rat. Histological examination of skeletal muscle reveals severe abnormalities indicating chronic underlying myopathy. The association of histological abnormalities with an acute, fatal syndrome clinically resembling malignant hyperthermia provides a strong basis for a new and extremely useful animal model to study this fatal disorder.

Liver cysts are commonly found incidentally from imaging scans or at autopsy. These benign neoplasms vary in size and represent a heterogeneous group of disorders, for which the demographics, risk factors, apparent inciting event, clinical presentation, and outcome are varied. Complications that can develop from a liver cyst include development of spontaneous hemorrhage, infection, and/or obstruction. Although the etiology of liver cysts varies, fatal rupture of a hemorrhagic liver cyst due to anabolic steroid use is a rare occurrence. In fact, there are few reported cases in journal literature. We report a case of a fatal liver cyst rupture with resultant hemoperitoneum in the presence of anabolic steroid (stanozolol) use.

Gastrointestinal manifestations of mitochondrial disorders: a systematic review

PubMed Central

Finsterer, Josef; Frank, Marlies

2016-01-01

Mitochondrial disorders (MIDs) due to respiratory-chain defects or nonrespiratory chain defects are usually multisystem conditions [mitochondrial multiorgan disorder syndrome (MIMODS)] affecting the central nervous system (CNS), peripheral nervous system, eyes, ears, endocrine organs, heart, kidneys, bone marrow, lungs, arteries, and also the intestinal tract. Frequent gastrointestinal (GI) manifestations of MIDs include poor appetite, gastroesophageal sphincter dysfunction, constipation, dysphagia, vomiting, gastroparesis, GI pseudo-obstruction, diarrhea, or pancreatitis and hepatopathy. Rare GI manifestations of MIDs include dry mouth, paradontosis, tracheoesophageal fistula, stenosis of the duodeno-jejunal junction, atresia or imperforate anus, liver cysts, pancreas lipomatosis, pancreatic cysts, congenital stenosis or obstruction of the GI tract, recurrent bowel perforations with intra-abdominal abscesses, postprandial abdominal pain, diverticulosis, or pneumatosis coli. Diagnosing GI involvement in MIDs is not at variance from diagnosing GI disorders due to other causes. Treatment of mitochondrial GI disease includes noninvasive or invasive measures. Therapy is usually symptomatic. Only for myo-neuro-gastro-intestinal encephalopathy is a causal therapy with autologous stem-cell transplantation available. It is concluded that GI manifestations of MIDs are more widespread than so far anticipated and that they must be recognized as early as possible to initiate appropriate diagnostic work-up and avoid any mitochondrion-toxic treatment.

Injury related to self-harm is one of the leading causes of global disease burden. As a formative work for a programme to implement comprehensive mental healthcare in a rural district in Ethiopia, we determined the 12-month prevalence of non-fatal suicidal behaviour as well as factors associated with this behaviour to understand the potential burden of the behaviour in the district. Population-based (n = 1485) and facility-based (n = 1014) cross-sectional surveys of adults, using standardised, interview-based measures for suicidality (items on suicide from the Composite International Diagnostic Interview), depressive symptoms (the Patient Health Questionnaire) and alcohol use disorders (Alcohol Use Disorder Investigation Test; AUDIT). The overall 12-month prevalence of non-fatal suicidal behaviour, consisting of suicidal ideation, plan and attempt, was 7.9 % (95 % Confidence Interval (CI) = 6.8 % to 8.9 %). The prevalence was significantly higher in the facility sample (10.3 %) compared with the community sample (6.3 %). The 12-month prevalence of suicide attempt was 4.4 % (95 % CI = 3.6 % to 5.3 %), non-significantly higher among the facility sample (5.4 %) compared with the community sample (3.8 %). Over half of those with suicidal ideation (56.4 %) transitioned from suicidal ideation to suicide attempt. Younger age, harmful use of alcohol and higher depression scores were associated significantly with increased non-fatal suicidal behaviours. The only factor associated with transition from suicidal ideation to suicide attempt was high depression score. Only 10.5 % of the sample with suicidal ideation had received any treatment for their suicidal behaviour: 10.8 % of the community sample and 10.2 % of the facility sample. Although help seeking increased with progression from ideation to attempt, there was no statistically significant difference between the groups. Non-fatal suicidal behaviour is an important public health problem in this rural district. A more in-depth understanding of the context of the occurrence of the behaviour, improving access to care and targeting depression and alcohol use disorder are important next steps. The role of other psychosocial factors should also be explored to assist the provision of holistic care.

The clinical presentation of panic disorder and panic attack overlaps many symptoms typically experienced in coronary heart disease (CHD). Etiological links between panic disorder and CHD are controversial and remain largely tenuous. This systematic review aims to pool together data regarding panic disorder with respect to incident CHD or myocardial infarction. Electronic databases (MEDLINE, EMBASE, PsycINFO and SCOPUS) will be searched using a search strategy exploding the topics for CHD and panic disorder. Authors and reference lists of included studies will also be contacted to identify additional published and unpublished studies. Eligibility criteria are as follows: persons without CHD who meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; Comparison: persons without CHD who do not meet criteria for panic disorder, panic attack, anxiety neurosis or elevated panic disorder symptoms; verified fatal and non-fatal CHD at follow-up; including coronary revascularization procedure, coronary artery disease, and myocardial infarction. Studies adopting self-report CHD will be ineligible. Screening will be undertaken by two independent reviewers with disagreements resolved through discussion. Data extraction will include original data specified as hazard ratios, risk ratios, and original cell data if available. Risk of bias assessment will be undertaken by two independent reviewers. Meta-analytic methods will be used to synthesize the data collected relating to the CHD outcomes with Cochrane Review Manager 5.3. This systematic review aims to clarify whether panic disorder is associated with elevated risk for subsequent CHD. An evaluation of the etiological links between panic disorder with incident CHD might inform evidence-based clinical practice and policy concerning triaging chest pain patients, diagnostic assessment, and psychiatric intervention with panic disorder patients.

Rostami-Nejad, Mohammad; Haldane, Thea; AlDulaimi, David; Alavian, Seyed Moayed; Zali, Mohammad Reza; Rostami, Kamran

2013-01-01

Context Celiac disease (CD) is defined as a permanent intolerance to ingested gluten. The intolerance to gluten results in immune-mediated damage of small intestine mucosa manifested by villous atrophy and crypt hyperplasia. These abnormalities resolve with initiationa gluten-free diet. Evidence Acquisition PubMed, Ovid, and Google were searched for full text articles published between 1963 and 2012. The associated keywords were used, and papers described particularly the impact of celiac disease on severity of liver disorder were identified. Results Recently evidence has emerged revealingthat celiac disease not only is associated with small intestine abnormalities and malabsorption, but is also a multisystem disorder affecting other systems outside gastrointestinal tract, including musculo-skeletal, cardiovascular and nervous systems. Some correlations have been assumed between celiac and liver diseases. In particular, celiac disease is associated with changes in liver biochemistry and linked to alter the prognosis of other disorders. This review will concentrate on the effect of celiac disease and gluten-free diets on the severity of liver disorders. Conclusions Although GFD effect on the progression of CD associated liver diseases is not well defined, it seems that GFD improves liver function tests in patients with a hypertransaminasemia.

Lysinuric protein intolerance (LPI): a multi organ disease by far more complex than a classic urea cycle disorder.

PubMed

Ogier de Baulny, Hélène; Schiff, Manuel; Dionisi-Vici, Carlo

2012-05-01

Lysinuric protein intolerance (LPI) is an inherited defect of cationic amino acid (lysine, arginine and ornithine) transport at the basolateral membrane of intestinal and renal tubular cells caused by mutations in SLC7A7 encoding the y(+)LAT1 protein. LPI has long been considered a relatively benign urea cycle disease, when appropriately treated with low-protein diet and l-citrulline supplementation. However, the severe clinical course of this disorder suggests that LPI should be regarded as a severe multisystem disease with uncertain outcome. Specifically, immune dysfunction potentially attributable to nitric oxide (NO) overproduction secondary to arginine intracellular trapping (due to defective efflux from the cell) might be a crucial pathophysiological route explaining many of LPI complications. The latter comprise severe lung disease with pulmonary alveolar proteinosis, renal disease, hemophagocytic lymphohistiocytosis with subsequent activation of macrophages, various auto-immune disorders and an incompletely characterized immune deficiency. These results have several therapeutic implications, among which lowering the l-citrulline dosage may be crucial, as excessive citrulline may worsen intracellular arginine accumulation.

Mitochondrial vasculopathy

PubMed Central

Finsterer, Josef; Zarrouk-Mahjoub, Sinda

2016-01-01

Mitochondrial disorders (MIDs) are usually multisystem disorders (mitochondrial multiorgan disorder syndrome) either on from onset or starting at a point during the disease course. Most frequently affected tissues are those with a high oxygen demand such as the central nervous system, the muscle, endocrine glands, or the myocardium. Recently, it has been shown that rarely also the arteries may be affected (mitochondrial arteriopathy). This review focuses on the type, diagnosis, and treatment of mitochondrial vasculopathy in MID patients. A literature search using appropriate search terms was carried out. Mitochondrial vasculopathy manifests as either microangiopathy or macroangiopathy. Clinical manifestations of mitochondrial microangiopathy include leukoencephalopathy, migraine-like headache, stroke-like episodes, or peripheral retinopathy. Mitochondrial macroangiopathy manifests as atherosclerosis, ectasia of arteries, aneurysm formation, dissection, or spontaneous rupture of arteries. The diagnosis relies on the documentation and confirmation of the mitochondrial metabolic defect or the genetic cause after exclusion of non-MID causes. Treatment is not at variance compared to treatment of vasculopathy due to non-MID causes. Mitochondrial vasculopathy exists and manifests as micro- or macroangiopathy. Diagnosing mitochondrial vasculopathy is crucial since appropriate treatment may prevent from severe complications. PMID:27231520

Leigh syndrome (LS) is the most common infantile mitochondrial encephalopathy. No treatment is currently available for this condition. Mice lacking Ndufs4, encoding NADH: ubiquinone oxidoreductase iron-sulfur protein 4 (NDUFS4) recapitulates the main findings of complex I (cI)-related LS, including severe multisystemic cI deficiency and progressive neurodegeneration. In order to develop a gene therapy approach for LS, we used here an AAV2/9 vector carrying the human NDUFS4 coding sequence (hNDUFS4). We administered AAV2/9-hNDUFS4 by intravenous (IV) and/or intracerebroventricular (ICV) routes to either newborn or young Ndufs4 -/- mice. We found that IV administration alone was only able to correct the cI deficiency in peripheral organs, whereas ICV administration partially corrected the deficiency in the brain. However, both treatments failed to improve the clinical phenotype or to prolong the lifespan of Ndufs4 -/- mice. In contrast, combined IV and ICV treatments resulted, along with increased cI activity, in the amelioration of the rotarod performance and in a significant prolongation of the lifespan. Our results indicate that extraneurological organs have an important role in LS pathogenesis and provide an insight into current limitations of adeno-associated virus (AAV)-mediated gene therapy in multisystem disorders. These findings warrant future investigations to develop new vectors able to efficiently target multiple organs.

Childhood abuse increases adult risk for morbidity and mortality. Less clear is how this "toxic" stress becomes embedded to influence health decades later, and whether protective factors guard against these effects. Early biological embedding is hypothesized to occur through programming of the neural circuitry that influences physiological response patterns to subsequent stress, causing wear and tear across multiple regulatory systems. To examine this hypothesis, we related reports of childhood abuse to a comprehensive 18-biomarker measure of multisystem risk and also examined whether presence of a loving parental figure buffers against the impact of childhood abuse on adult risk. A total of 756 subjects (45.8% white, 42.7% male) participated in this ancillary substudy of the Coronary Artery Risk Development in Young Adults Study. Childhood stress was determined by using the Risky Families Questionnaire, a well-validated retrospective self-report scale. Linear regression models adjusting for age, sex, race, parental education, and oral contraceptive use found a significant positive relationship between reports of childhood abuse and multisystem health risks [B (SE) = 0.68 (0.16); P < 0.001]. Inversely, higher amounts of reported parental warmth and affection during childhood was associated with lower multisystem health risks [B (SE) = -0.40 (0.14); P < 0.005]. A significant interaction of abuse and warmth (P < 0.05) was found, such that individuals reporting low levels of love and affection and high levels of abuse in childhood had the highest multisystem risk in adulthood.

Behçet's disease is a chronic relapsing multisystemic inflammatory disorder characterized by four major symptoms (oral aphthous ulcers, genital ulcers, skin lesions, and ocular lesions) and occasionally by five minor symptoms (arthritis, gastrointestinal ulcers, epididymitis, vascular lesions, and central nervous system symptoms). Although the etiology of Behçet's disease is still unknown, there have been recent advances in immunopathogenic studies, genome-wide association studies, animal models, diagnostic markers, and new biological agents. These advances have improved the clinical understanding of Behçet's disease and have enabled us to develop new treatment strategies for this intractable disease, which remains one of the leading causes of blindness.

2010-01-01

Lymphangioleiomyomatosis (LAM) is a multisystem disorder associated with proliferation of smooth muscle-like cells, which leads to destruction of lung parenchyma. Subjective grading of LAM on HRCT is imprecise and can be arduous especially in cases with severe involvement. We propose a computer-aided evaluation system that grades LAM involvement based on analysis of lung texture patterns. A committee of support vector machines is employed for classification. The system was tested on 36 patients. The computer grade demonstrates good correlation with subjective radiologist grade (R=0.91, p<0.0001) and pulmonary functional tests (R=0.85, p<0.0001). The grade also provides precise progression assessment of disease over time. PMID:21625320

Myotonic dystrophy (Dystrophia Myotonica, DM) is the most frequently inherited neuromuscular disease of adult life. It is a multisystemic disease with major cardiac involvement. Core features of myotonic dystrophy are myotonia, muscle weakness, cataract, respiratory failure and cardiac conduction abnormalities. Classical DM, first described by Steinert and called Steinert's disease or DM1 (Dystrophia Myotonica type 1) has been identified as an autosomal dominant disorder associated with the presence of an abnormal expansion of a CTG trinucleotide repeat in the 3' untranslated region of DMPK gene on chromosome 19. This review will mainly focus on the various aspects of cardiac involvement in DM1 patients and the current role of cardiac pacing in their treatment.

Here, we report and investigate the genomic alterations of two novel cases of Non-Hodgkin Lymphoma (NHL) in children with Williams-Beuren syndrome (WBS), a multisystem disorder caused by 7q11.23 hemizygous deletion. Additionally, we report the case of a child with NHL and a somatic 7q11.23 deletion. Although the WBS critical region has not yet been identified as a susceptibility locus in NHL, it harbors a number of genes involved in DNA repair. The high proportion of pediatric NHL reported in WBS is intriguing. Therefore, the role of haploinsufficiency of genes located at 7q11.23 in lymphomagenesis deserves to be investigated.

Schimke immuno-osseous dysplasia (SIOD) is a rare autosomal recessive multisystemic disorder caused by mutations of the SMARCAL 1 gene (SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a-like 1). Main clinical features are: disproportional growth deficiency due to spondyloepiphyseal dysplasia, nephrotic syndrome with focal and segmental glomerulosclerosis, and defective cellular immunity. Patients with severe SIOD have life-limiting complications like cerebral ischemia due to vaso-occlusive processes. Only a few patients reached adulthood. The clinical course of four adult SIOD patients is presented. Even patients with severe SIOD can reach adulthood. Therefore, doctors working in the field of internal medicine and family doctors should be familiar with the clinical picture of SIOD.

Pearson syndrome (PS) is a rare multisystem mitochondrial disorder of hematopoietic system, characterized by refractory sideroblastic anemia, pancytopenia, exocrine pancreatic insufficiency, and variable neurologic, hepatic, renal, and endocrine failure. We describe a six-month-old female infant with Pearson marrow syndrome who presented with neurological manifestations. She had several episodes of seizures. Hematopoietic abnormalities were macrocytic anemia and neutropenia. Bone marrow aspiration revealed a cellular marrow with marked vacuolization of erythroid and myeloid precursors. Analysis of mtDNA in peripheral blood showed 8.5 kb deletion that was compatible with the diagnosis of PS. PS should be considered in infants with neurologic diseases, in patients with cytopenias, and also in patients with acidosis or refractory anemia.

Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patient was treated with L-thyroxine at 0.15 mg daily. However, during admission, he developed symptoms of cardiac tamponade. Closed pericardiostomy was performed, after which the patient's chest discomfort improved, and his vital signs stabilized.

Prader-Willi syndrome(PWS) is a complex multisystem genetic disorder, of which characteristic phenotypes include neonatal hypotonia, hyperphagia resulting in obesity, mental retardation, hypogonadism, and behavioral and psychiatric problems. The diagnosis can be obtained as early as during neonatal period thanks to development of genetic testing. Clinical features of PWS will change depending on age, although core phenotypes of hyperphagia, obesity and psychiatric issues stay for lifetime. Therefore, integrated multidisciplinary approach starting from neonatal period is mandatory to ensure optimal management to improve lifelong quality of life. For successful transition from childhood to adulthood, multidisciplinary team need to share clinical information, and should keep the same policy about food, environment and psychiatric issues.

Cystic fibrosis is an autosomal recessive disorder characterized by chronic progressive multisystem involvement. AH1N1 virus infections caused classic influenza symptoms in the majority of cystic fibrosis patients while others experienced severe outcomes. We report a case of late incidental cystic fibrosis diagnosis in a young Caucasian man suffering from respiratory failure following infection due to AH1N1 influenza virus. The patient was admitted to our department with fever, cough, and dyspnea at rest unresponsive to antibiotics CONCLUSIONS: Late diagnosis of cystic fibrosis in uncommon. This report highlights the importance of early cystic fibrosis diagnosis to minimize risk of occurrence of potential life-threatening complications.

Huffing air conditioner fluid: a cool way to die?

PubMed

Phatak, Darshan R; Walterscheid, Jeffrey

2012-03-01

"Huffing," the form of substance abuse involving inhalants, is growing in popularity because of the ease and availability of chemical inhalants in many household products. The purpose in huffing is to achieve euphoria when the chemicals in question interact with the central nervous system in combination with oxygen displacement. The abuser is lulled into a false sense of safety despite the well-documented potential for lethal cardiac arrhythmia and the effects of chronic inhalant abuse, including multisystem organ failure, and brain damage. Huffing air conditioner fluid is a growing problem given the accessibility to outdoor units and their fluid components, such as difluorochloromethane(chlorodifluoromethane, Freon), and we have classified multiple cases of accidental death due to the toxicity of difluorochloromethane. Given the ubiquity of these devices and the vast lack of gating or security devices, they make an inviting target for inhalant abusers. Acute huffing fatalities have distinct findings that are present at the scene, given the position of the decedent and proximity to the air conditioner unit. The purpose of the autopsy in these cases is to exclude other potential causes of death and to procure specimens for toxicological analysis.

Bipolar Disorder in Aviation Medicine.

2017-01-01

One of the most difficult challenges in aviation medicine is to diagnose, as early as possible, pilots with psychiatric disorders that may impair pilot performance and increase the risk of incidents and accidents. This diagnosis applies particularly to bipolar disorder (BD), where return to flying duty is not an option in the majority of cases. BD is a long-term mental disorder presenting remittent depressive, hypomanic, manic, or mixed episodes between low symptomatic or asymptomatic intermediate periods. Onset in most cases is in late teen or early adult years. Suicidal intentions and suicide risk are significantly elevated in individuals with BD compared to the general population. A systematic literature search was performed of BD and aviation accidents and the National Transportation Safety Board database of fatal general aviation accidents was searched. One case report and two database reports of interest from 1994 to 2014 were identified. The findings set a minimum frequency of BD in general aviation fatalities to be approximately 2 out of 8648 (0.023%) in the United States. The reported incidence may underestimate the real number of BD cases for several reasons, including the fact that the medical history of pilots is not always available or is sometimes not the primary interest of a safety investigation. This study suggests that the demarcation of psychiatric disorder related to fitness to fly is an important step in safety.Vuorio A, Laukkala T, Navathe P, Budowle B, Bor R, Sajantila A.

Myotonic Dystrophy Type 1 Management and Therapeutics.

PubMed

Smith, Cheryl A; Gutmann, Laurie

2016-12-01

Myotonic dystrophy (DM1) is the most common form of adult muscular dystrophy. It is a multisystem disorder with a complex pathophysiology. Although inheritance is autosomal dominant, disease variability is attributed to anticipation, a maternal expansion bias, variable penetrance, somatic mosaicism, and a multitude of aberrant pre-mRNA splicing events. Patient presentations range from asymptomatic or mild late onset adult to severe congenital forms. Multiple organ systems may be affected. Patients may experience early cataracts, myotonia, muscle weakness/atrophy, fatigue, excessive daytime sleepiness, central/obstructive apnea, respiratory failure, cardiac arrhythmia, insulin resistance, dysphagia, GI dysmotility, cognitive impairment, Cluster C personality traits, and/or mood disorders. At present, there is no curative or disease-modifying treatment, although clinical treatment trials have become more promising. Management focuses on genetic counseling, preserving function and independence, preventing cardiopulmonary complications, and symptomatic treatment (e.g., pain, myotonia, hypersomnolence, etc.). Currently, there is an increasing international consensus on monitoring and treatment options for these patients which necessitates a multidisciplinary team to provide comprehensive, coordinated clinical care.

The objectives of this review are to describe the clinical manifestations of the growing spectrum of monogenic autoinflammatory diseases including recently described syndromes. The autoinflammatory diseases can be grouped based on clinical findings: 1. the three classic hereditary “periodic fever syndromes”, familial Mediterranean Fever (FMF); TNF receptor associated periodic syndrome (TRAPS); and mevalonate kinase deficiency/hyperimmunoglobulinemia D and periodic fever syndrome (HIDS); 2. the cryopyrin associated periodic syndromes (CAPS), comprising familial cold autoinflammatory syndrome (FCAS), Muckle-Wells syndrome (MWS) and neonatal-onset multisystem inflammatory disease (NOMID) or CINCA, and; 3. pediatric granulomatous arthritis (PGA); 4. disorders presenting with skin pustules, including deficiency of interleukin 1 receptor antagonist (DIRA); Majeed syndrome; pyogenic arthritis, pyoderma gangrenosum and acne (PAPA) syndrome; deficiency of interleukin 36 receptor antagonist (DITRA); CARD14 mediated psoriasis (CAMPS), and early-onset inflammatory bowel diseases (EO-IBD); 5. inflammatory disorders caused by mutations in proteasome components, the proteasome associated autoinflammatory syndromes (PRAAS) 6. very rare conditions presenting with autoinflammation and immunodeficiency.

Because of its high prevalence, fibromyalgia (FM) is a major general health issue. Myotonic dystrophy type 2 (DM2) is a recently described autosomal-dominant multisystem disorder. Besides variable proximal muscle weakness, myotonia, and precocious cataracts, muscle pain and stiffness are prominent presenting features of DM2. After noting that several of our mutation-positive DM2 patients had a previous diagnosis of FM, suggesting that DM2 may be misdiagnosed as FM, we invited 90 randomly selected patients diagnosed as having FM to undergo genetic testing for DM2. Of the 63 patients who agreed to participate, 2 (3.2%) tested positive for the DM2 mutation. Their cases are described herein. DM2 was not found in any of 200 asymptomatic controls. We therefore suggest that the presence of DM2 should be investigated in a large sample of subjects diagnosed as having FM, and clinicians should be aware of overlap in the clinical presentation of these 2 distinct disorders.

Epidermolysis bullosa (EB) has become recognized as a multisystem disorder that poses a number of pre-, intra-, and postoperative challenges. While anesthesiologists have long appreciated the potential difficult intubation in patients with EB, other systems can be affected by this disorder. Hematologic, cardiac, skeletal, gastrointestinal, nutritional, and metabolic deficiencies are foci of preoperative medical care, in addition to the airway concerns. Therefore, multidisciplinary planning for operative care is imperative. A multinational, interdisciplinary panel of experts assembled in Santiagio, Chile to review the best practices for perioperative care of patients with EB. This paper presents guidelines that represent a synthesis of evidence-based approaches and the expert consensus of this panel and are intended to aid physicians new to caring for patients with EB when operative management is indicated. With proper medical optimization and attention to detail in the operating room, patients with EB can have an uneventful perioperative course.

Neurofibromatosis type 1 (NF1) is a heterogeneous, common, neurocutaneous disorder presenting different complications during a life span, including cerebrovascular dysplasia. To our knowledge this is the first reported case of NF1 associated with vertebrobasilar dolichoectasia and pontine ischemic stroke. We describe a 57-year-old man with NF1 who presented an acute onset right-sided facial palsy and hemiplegia, dysarthria, and gait imbalance. Magnetic resonance imaging showed an acute left paramedian pontine infarct and a hypoplastic right vertebral artery. Brain Computed Tomography Angiography revealed the occurrence of vertebrobasilar dolichoectasia. Co-occurrence of VBD and NF1 might not be merely casual and it may significantly heighten the mortality rate in this multisystem disorder. We suggest a possible role of VBD in the genesis of our patient's clinical-radiological features and prompt the early detection of asymptomatic arteriopathy in individuals with NF1 in order to ameliorate patients' quality of life and life expectancy.

Coenzyme Q10 deficiencies in neuromuscular diseases.

PubMed

Artuch, Rafael; Salviati, Leonardo; Jackson, Sandra; Hirano, Michio; Navas, Plácido

2009-01-01

Coenzyme Q (CoQ) is an essential component of the respiratory chain but also participates in other mitochondrial functions such as regulation of the transition pore and uncoupling proteins. Furthermore, this compound is a specific substrate for enzymes of the fatty acids beta-oxidation pathway and pyrimidine nucleotide biosynthesis. Furthermore, CoQ is an antioxidant that acts in all cellular membranes and lipoproteins. A complex of at least ten nuclear (COQ) genes encoded proteins synthesizes CoQ but its regulation is unknown. Since 1989, a growing number of patients with multisystemic mitochondrial disorders and neuromuscular disorders showing deficiencies of CoQ have been identified. CoQ deficiency caused by mutation(s) in any of the COQ genes is designated primary deficiency. Other patients have displayed other genetic defects independent on the CoQ biosynthesis pathway, and are considered to have secondary deficiencies. This review updates the clinical and molecular aspects of both types of CoQ deficiencies and proposes new approaches to understanding their molecular bases.

Marden-Walker syndrome is challenging to diagnose, as there is significant overlap with other multi-system congenital contracture syndromes including Beals congenital contractural arachnodactyly, D4ST1-Deficient Ehlers-Danlos syndrome (adducted thumb-clubfoot syndrome), Schwartz-Jampel syndrome, Freeman-Sheldon syndrome, Cerebro-oculo-facio-skeletal syndrome, and Van den Ende-Gupta syndrome. We discuss this differential diagnosis in the context of a boy from a consanguineous union with Van den Ende-Gupta syndrome, a diagnosis initially confused by the atypical presence of intellectual disability. SNP microarray and whole exome sequencing identified a homozygous frameshift mutation (p.L870V) in SCARF2 and predicted damaging mutations in several genes, most notably DGCR2 (p.P75L) and NCAM2 (p.S147G), both possible candidates for this child's intellectual disability. We review distinguishing features for each Marden-Walker-like syndrome and propose a clinical algorithm for diagnosis among this spectrum of disorders. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Changing the world: the design and implementation of comprehensive continuous integrated systems of care for individuals with co-occurring disorders.

PubMed

Minkoff, Kenneth; Cline, Christie A

2004-12-01

This article has described the CCISC model and the process of implementation of systemic implementation of co-occurring disorder services enhancements within the context of existing resources. Four projects were described as illustrations of current implementation activities. Clearly, there is need for improved services for these individuals, and increasing recognition of the need for systemic change models that are effective and efficient. The CCISC model has been recognized by SAMHSA as a consensus best practice for system design, and initial efforts at implementation appear to be promising. The existing toolkit may permit a more formal process of data-driven evaluation of system, program, clinician, and client outcomes, to better measure the effectiveness of this approach. Some projects have begun such formal evaluation processes, but more work is needed, not only with individual projects, but also to develop opportunities for multi-system evaluation, as more projects come on line.

The only systematic studies of attacks on public figures come from the USA. These studies de-emphasize the role of mental illness and suggest threats are of no predictive value. This study re-examines these questions through a study of attacks on European politicians. All non-terrorist attacks on elected politicians in Western Europe between 1990 and 2004 were analysed. Twenty-four attacks were identified, including five involving fatalities, and eight serious injuries. Ten attackers were psychotic, four drunk, nine politically motivated and one unclassifiable. Eleven attackers evidenced warning behaviours. The mentally disordered, most of whom gave warnings, were responsible for most of the fatal and seriously injurious attacks. A greater awareness of the link between delusional fixations on public figures and subsequent attacks could aid prevention. Equally importantly, recognition would encourage earlier intervention in people who, irrespective of whether they eventually attack, have delusional preoccupations which ruin their lives.

Myasthenic syndromes due to defects in COL13A1 and in the N-linked glycosylation pathway.

The congenital myasthenic syndromes (CMS) are hereditary disorders of neuromuscular transmission. The number of cases recognized, at around 1:100,000 in the United Kingdom, is increasing with improved diagnosis. The advent of next-generation sequencing has facilitated the discovery of many genes that harbor CMS-associated mutations. An emerging group of CMS, characterized by a limb-girdle pattern of muscle weakness, is caused by mutations in genes that encode proteins involved in the initial steps of the N-linked glycosylation pathway, which is surprising, since this pathway is found in all mammalian cells. However, mutations in these genes may also give rise to multisystem disorders (congenital disorders of glycosylation) or muscle disorders where the myasthenic symptoms constitute only one component within a wider phenotypic spectrum. We also report a CMS due to mutations in COL13A1, which encodes an extracellular matrix protein that is concentrated at the neuromuscular junction and highlights a role for these extracellular matrix proteins in maintaining synaptic stability that is independent of the AGRN/MuSK clustering pathway. Knowledge about the neuromuscular synapse and the different proteins involved in maintaining its structure as well as function enables us to tailor treatments to the underlying pathogenic mechanisms. © 2018 New York Academy of Sciences.

Growth hormone deficiency in a patient with mitochondrial disease.

2015-09-01

Mitochondrial respiratory chain (MRC) disorders, defined as primary diseases of the oxidative phosphorylation system, are a protean group of metabolic disorders, difficult to diagnose and classify. The diagnosis is complex and requires the integration of information obtained by clinical, laboratory testing, imaging and muscle biopsy. They may be associated with endocrine disorders, including hypothyroidism, diabetes mellitus, hyperinsulinemia and growth hormone (GH) deficiency. We describe a case of five years old male with polymalformative syndrome with a systemic involvement. At 6 months of age, he was sent to metabolic consultation because of facial dysmorphy and short stature. During the investigation it was diagnosed at the boy a growth hormone deficiency and because of his multisystemic involvement, muscle biopsy was carried out and showed reduced activity of complex II (38%) of the mitochondrial respiratory chain. Currently, the boy is under GH therapy with growth in the 5th percentile and coenzime Q10. Mitochondrial biology is one of the fastest growing areas in genetics and medicine. Disturbances in mitochondrial metabolism are now known to play a role not only in rare childhood diseases, but also in many common diseases of aging. In mitochondrial disorders, short stature is a common symptom, but its underlying lesion, growth hormone deficiency, is rarely investigated.

Anti-tissue transglutaminase antibodies and their role in the investigation of coeliac disease.

Coeliac disease (CD), caused by an inappropriate T-cell-mediated immune response to the ingestion of cereal proteins in genetically susceptible individuals, is a common disorder with a prevalence of about 1% in Caucasian populations. It has a strong association with other autoimmune disorders, particularly type 1 diabetes and autoimmune thyroid disease. Although primarily affecting the small bowel, CD is a multisystem disorder and the adult or child patient may initially present to a wide range of clinical specialties. The concept of the 'coeliac iceberg' has been used to emphasize that many cases currently remain undiagnosed. The identification of tissue transglutaminase (TGA)-2 as the antigen against which the autoantibodies are directed has led to a greater understanding of the pathogenesis of CD and to the development of improved serological tests. Enzyme-linked immunoassays using human tissue TGA as antigen have high diagnostic sensitivity and specificity for the detection of CD. This review examines the evidence for adopting IgA anti-tissue TGA as the first-line diagnostic test for CD. It recommends a laboratory algorithm for the use and interpretation of TGA to enable the clinical laboratory to play a full part in detecting and monitoring a disorder that is eminently treatable once the diagnosis has been considered and confirmed.

Hypomelanosis of Ito: neurological and psychiatric pictures in developmental age.

PubMed

Parisi, L; Di Filippo, T; Roccella, M

2012-02-01

Hypomelanosis of Ito (HOI) is a multisystem neurocutaneous disorder. In the described cases, cutaneous manifestations (unilateral or bilateral streaks and swirls of hypomelanosis with regular and confluent borders) and extracutaneous abnormalities are often associated. Extracutaneous abnormalities involve the musculoskeletal system (scoliosis, vertebral anomalies, cranial-facial malformations) and other organs, as well as the central nervous system (CNS). The most significant anomalies of the CNS are psychomotor retardation and cognitive deficit. Autism, epilepsy, language disorders, cerebral malformations (neural migration disorders, cerebral hypoplasia, cortical atrophy, agenesis of the corpus callosum) are sometimes present. Numerous abnormal chromosomal patterns have been observed. HOI is usually a sporadic disorder; though autosomal dominant transmission has been suggested, recessive and X-linked inheritance patterns have also been reported. This study describes five children with HOI presenting with various features of the clinical spectrum of the syndrome. Some of these cases were referred for psychomotor therapy as part of an integrated neuropsychologic and psychomotor treatment support program. In this view, psychomotor treatment aims to promote the emotional-relational component, to overcome rigid divisions, and to integrate learning-related cognitive aspects with psychodynamic concepts. Finally, the goals of psychological and social support are to help the parents accept their child's handicap, understand the child's behavior, plan future pregnancies, and foster an environment for their child's integration.

Gastrointestinal disorders associated with migraine: A comprehensive review

Migraine is a recurrent and commonly disabling primary headache disorder that affects over 17% of women and 5%-8% of men. Migraine susceptibility is multifactorial with genetic, hormonal and environmental factors all playing an important role. The physiopathology of migraine is complex and still not fully understood. Many different neuropeptides, neurotransmitters and brain pathways have been implicated. In connection with the myriad mechanisms and pathways implicated in migraine, a variety of multisystemic comorbidities (e.g., cardiovascular, psychiatric and other neurological conditions) have been found to be closely associated with migraine. Recent reports demonstrate an increased frequency of gastrointestinal (GI) disorders in patients with migraine compared with the general population. Helicobacter pylori infection, irritable bowel syndrome, gastroparesis, hepatobiliary disorders, celiac disease and alterations in the microbiota have been linked to the occurrence of migraine. Several mechanisms involving the gut-brain axis, such as a chronic inflammatory response with inflammatory and vasoactive mediators passing to the circulatory system, intestinal microbiota modulation of the enteric immunological milieu and dysfunction of the autonomic and enteric nervous system, have been postulated to explain these associations. However, the precise mechanisms and pathways related to the gut-brain axis in migraine need to be fully elucidated. In this review, we survey the available literature linking migraine with GI disorders. We discuss the possible physiopathological mechanisms, and clinical implications as well as several future areas of interest for research. PMID:27688656

New insights into visceral hypersensitivity —clinical implications in IBS

PubMed Central

Zhou, QiQi; Verne, G. Nicholas

2012-01-01

A subset of patients with IBS have visceral hypersensitivity and/or somatic hypersensitivity. Visceral hypersensitivity might have use as a clinical marker of IBS and could account for symptoms of urgency for bowel movements, bloating and abdominal pain. The mechanisms that lead to chronic visceral hypersensitivity in patients who have IBS are unclear. However, several working models may be considered, including: nociceptive input from the colon that leads to hypersensitivity; increased intestinal permeability that induces a visceral nociceptive drive; and alterations in the expression of microRNAs in gastrointestinal tissue that might be delivered via blood microvesicles to other target organs, such as the peripheral and/or central nervous system. As such, the chronic visceral hypersensitivity that is present in a subset of patients with IBS might be maintained by both peripheral and central phenomena. The theories underlying the development of chronic visceral hypersensitivity in patients with IBS are supported by findings from new animal models in which hypersensitivity follows transient inflammation of the colon. The presence of somatic hypersensitivity and an alteration in the neuroendocrine system in some patients who have IBS suggests that multisystemic factors are involved in the overall disorder. Thus, IBS is similar to other chronic pain disorders, such as fibromyalgia, chronic regional pain disorder and temporomandibular joint disorder, as chronic nociceptive mechanisms are activated in all of these disorders.

Global burden of mental disorders among children aged 5-14 years.

Baranne, Marie Laure; Falissard, Bruno

2018-01-01

The global burden of disease (GBD) study provides information about fatal and non-fatal health outcomes around the world. The objective of this work is to describe the burden of mental disorders among children aged 5-14 years in each of the six regions of the World Health Organisation. Data come from the GBD 2015 study. Outcomes: disability-adjusted life-years (DALYs) are the main indicator of GBD studies and are built from years of life lost (YLLs) and years of life lived with disability (YLDs). Mental disorders are among the leading causes of YLDs and of DALYs in Europe and the Americas. Because of the importance of infectious diseases, mental disorders appear marginal in Africa for YLLs although they play an important role in YLDs there. Because the epidemiological transition that has taken place in Europe and the Americas (i.e., a switch from acute and infectious conditions to chronic and mental health issues) is likely to happen sooner or later across the entire planet, mental health problems in youth are likely to become one of the main public health challenges of the twenty-first century. These results should improve health care if policy-makers use them to develop health policies to meet the real needs of populations (especially children) today.

Mitochondrial disorders are frequently encountered inherited diseases characterized by unexplained multisystem involvement with a chronic, intermittent, or progressive nature. The objective of this paper is to describe the profile of patients with mitochondrial disorders in South Africa. Patients with possible mitochondrial disorders were accessed over 10 years. Analyses for respiratory chain and pyruvate dehydrogenase complex enzymes were performed on muscle. A diagnosis of a mitochondrial disorder was accepted only if an enzyme activity was deficient. Sixty-three patients were diagnosed with a mitochondrial disorder, including 40 African, 20 Caucasian, one mixed ancestry, and two Indian patients. The most important findings were the difference between African patients and other ethnicities: respiratory chain enzyme complexes CI+III or CII+III deficiencies were found in 52.5% of African patients, being of statistical significance (p value = 0.0061). They also presented predominantly with myopathy (p value = 0.0018); the male:female ratio was 1:1.2. Twenty-five (62.5%) African patients presented with varying degrees of a myopathy accompanied by a myopathic face, high palate, and scoliosis. Fourteen of these 25 also had ptosis and/or progressive external ophthalmoplegia. No patients of other ethnicities presented with this specific myopathic phenotype. Caucasian patients (16/20) presented predominantly with central nervous system involvement. Of the South African pediatric neurology patients, Africans are more likely to present with myopathy and CII+III deficiency, and Caucasian patients are more likely to present with encephalopathy or encephalomyopathy.

The cutis laxa syndromes are multisystem disorders that share loose redundant inelastic and wrinkled skin as a common hallmark clinical feature. The underlying molecular defects are heterogeneous and 13 different genes have been involved until now, all of them being implicated in elastic fiber assembly. We provide here molecular and clinical characterization of three unrelated patients with a very rare phenotype associating cutis laxa, facial dysmorphism, severe growth retardation, hyperostotic skeletal dysplasia, and intellectual disability. This disorder called Lenz-Majewski syndrome (LMS) is associated with gain of function mutations in PTDSS1, encoding an enzyme involved in phospholipid biosynthesis. This report illustrates that LMS is an unequivocal cutis laxa syndrome and expands the clinical and molecular spectrum of this group of disorders. In the neonatal period, brachydactyly and facial dysmorphism are two early distinctive signs, later followed by intellectual disability and hyperostotic skeletal dysplasia with severe dwarfism allowing differentiation of this condition from other cutis laxa phenotypes. Further studies are needed to understand the link between PTDSS1 and extra cellular matrix assembly. © 2018 The Authors.

Ehlers-Danlos Syndrome, Hypermobility Type: An Underdiagnosed Hereditary Connective Tissue Disorder with Mucocutaneous, Articular, and Systemic Manifestations

Castori, Marco

2012-01-01

Ehlers-Danlos syndrome, hypermobility type, constituting a phenotypic continuum with or, perhaps, corresponding to the joint hypermobility syndrome (JHS/EDS-HT), is likely the most common, though the least recognized, heritable connective tissue disorder. Known for decades as a hereditary condition with predominant rheumatologic manifestations, it is now emerging as a multisystemic disorder with widespread manifestations. Nevertheless, the practitioners' awareness of this condition is generally poor and most patients await years or, perhaps, decades before reaching the correct diagnosis. Among the various sites of disease manifestations, skin and mucosae represent a neglected organ where the dermatologist can easily spot diagnostic clues, which consistently integrate joint hypermobility and other orthopedic/neurologic manifestations at physical examination. In this paper, actual knowledge on JHS/EDS-HT is summarized in various sections. Particular attention has been posed on overlooked manifestations, including cutaneous, mucosal, and oropharyngeal features, and early diagnosis techniques, as a major point of interest for the practicing dermatologist. Actual research progresses on JH/EDS-HT envisage an unexpected link between heritable dysfunctions of the connective tissue and a wide range of functional somatic syndromes, most of them commonly diagnosed in the office of various specialists, comprising dermatologists.

Modifiers and mechanisms of multi-system polyglutamine neurodegenerative disorders: lessons from fly models.

PubMed

Mallik, Moushami; Lakhotia, Subhash C

2010-12-01

Polyglutamine (polyQ) diseases, resulting from a dynamic expansion of glutamine repeats in a polypeptide, are a class of genetically inherited late onset neurodegenerative disorders which, despite expression of the mutated gene widely in brain and other tissues, affect defined subpopulations of neurons in a disease-specific manner. We briefly review the different polyQ-expansion-induced neurodegenerative disorders and the advantages of modelling them in Drosophila. Studies using the fly models have successfully identified a variety of genetic modifiers and have helped in understanding some of the molecular events that follow expression of the abnormal polyQ proteins. Expression of the mutant polyQ proteins causes, as a consequence of intra-cellular and inter-cellular networking, mis-regulation at multiple steps like transcriptional and posttranscriptional regulations, cell signalling, protein quality control systems (protein folding and degradation networks), axonal transport machinery etc., in the sensitive neurons, resulting ultimately in their death. The diversity of genetic modifiers of polyQ toxicity identified through extensive genetic screens in fly and other models clearly reflects a complex network effect of the presence of the mutated protein. Such network effects pose a major challenge for therapeutic applications.

Neuro-neutrophilic diseases are multisystem inflammatory disorders that include neuro-Behçet and neuro-Sweet disease. These disorders ectopically damage the nervous system due to the abnormal chemotaxis of neutrophils. The neutrophils' chemotaxis is induced by oral muco-cutaneous bacterial infections and the dysregulation of cytokines, including interleukins. The frequencies of human leukocyte antigen (HLA)-B51 in neuro-Behçet disease and HLA-B54 as well as Cw1 in neuro-Sweet disease significantly higher than the levels present in Japanese normal controls. Notably, their frequencies are also higher in patients exhibiting neurological complications than in patients without neurological complications. These HLA types are considered risk factors that are directly related to the etiology of these diseases. Prednisolone and colchicine, which suppress neutrophil activation, are used to treat the acute phase of both diseases. Alternatively, dapsone is prescribed to prednisolone-dependent recurrent cases of neuro-Sweet disease. Dementia is a neurological symptom of these disorders, especially in the chronic progressive subtype of neuro-Behçet disease. Other immunosuppressant drugs, including methotrexate and infliximab, are administered to patients with the chronic progressive type of neuro-Behçet disease. Neuro-neutrophilic diseases are a form of dementia considered treatable.

Albinism and lung fibrosis in a young man - the first case of adult Hermansky-Pudlak Syndrome reported in Malaysia.

PubMed

Liza, A F; Aziah, A M

2012-12-01

A young gentleman of Indian descent with oculacutaneous albinism (OCA) was found to have severe pulmonary fibrosis at first presentation. Following investigations, he was diagnosed with Hermansky-Pudlak Syndrome (HPS). It is a genetic condition characterised by albinism, bleeding diathesis and multisystem disorder observed in individuals of particular descents. Although there is no curative treatment apart from lung transplantation, preventive measures to minimise pulmonary insult may change the natural history of the disease. Therefore HPS should be actively sought, monitored and risk factors addressed in individuals with OCA and bleeding diathesis particularly those of Indian descent as they may develop serious complications such as pulmonary fibrosis in the future.

We report the clinical, biochemical, and molecular findings in two brothers with encephalopathy and multi-systemic disease. Abnormal transferrin glycoforms were suggestive of a type I congenital disorder of glycosylation (CDG). While exome sequencing was negative for CDG related candidate genes, the testing revealed compound heterozygous mutations in the mitochondrial elongation factor G gene (GFM1). One of the mutations had been reported previously while the second, novel variant was found deep in intron 6, activating a cryptic splice site. Functional studies demonstrated decreased GFM1 protein levels, suggested disrupted assembly of mitochondrial complexes III and V and decreased activities of mitochondrial complexes I and IV, all indicating combined OXPHOS deficiency.

Giant trochanteric pressure sore: Use of a pedicled chimeric perforator flap for cover

PubMed Central

2009-01-01

Pressure sores are increasing in frequency commensurate with an ageing population with multi-system disorders and trauma. Numerous classic options are described for providing stable wound cover. With the burgeoning knowledge on perforator anatomy, recent approaches focus on the use of perforator-based flaps in bedsore surgery. A giant neglected trochanteric pressure sore in a paraplegic is presented. Since conventional options of reconstruction appeared remote, the massive ulcer was successfully managed by a chimeric perforator-based flap. The combined muscle and fasciocutaneous flaps were raised as separate paddles based on the anterolateral thigh perforator branches and provided stable cover without complications. Perforators allow versatility in managing complex wounds without compromising on established principles. PMID:19881035

A Novel Mutation on RAF1 in Association with Fetal Findings Suggestive of Noonan Syndrome.

PubMed

Kneitel, Anna W; Norby, Audrey; Vettraino, Ivana; Treadwell, Marjorie C

2015-01-01

Noonan syndrome is a multisystem genetic disorder caused by genes encoding proteins involved in the RAS-MAPK pathway. Affected fetuses have variable presentations ranging from the absence of prenatal findings to increased nuchal fold, cystic hygromas, pleural effusions, cardiac malformations, or skin edema. We describe a male fetus who had features consistent with Noonan syndrome at the time of fetal anatomic survey, including hydrops and a possible cardiac defect. Subsequent scan revealed persistent bilateral pleural effusions (with predominance of lymphocytes). After bilateral thoracoamniotic shunt placement, the fetus did well and delivered at term. Prenatal testing revealed an S650F missense mutation in the RAF1 gene, which had not previously been associated with Noonan syndrome.

Wilson disease is a rare but important disorder of copper metabolism, with a failure to excrete copper appropriately into bile. It is a multisystem condition with presentations across all branches of medicine. Diagnosis can be difficult and requires a high index of suspicion. It should be considered in unexplained liver disease particularly where neuropsychiatric features are also present. Treatments are available for all stages of disease. A particularly important presentation not to overlook is acute liver failure which carries a high mortality risk and may require urgent liver transplantation. Here, we provide an overview of this complex condition. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.

Vici syndrome is a progressive neurodevelopmental multisystem disorder due to recessive mutations in the key autophagy gene EPG5. We report genetic, clinical, neuroradiological, and neuropathological features of 50 children from 30 families, as well as the neuronal phenotype of EPG5 knock-down in Drosophila melanogaster. We identified 39 different EPG5 mutations, most of them truncating and predicted to result in reduced EPG5 protein. Most mutations were private, but three recurrent mutations (p.Met2242Cysfs*5, p.Arg417*, and p.Gln336Arg) indicated possible founder effects. Presentation was mainly neonatal, with marked hypotonia and feeding difficulties. In addition to the five principal features (callosal agenesis, cataracts, hypopigmentation, cardiomyopathy, and immune dysfunction), we identified three equally consistent features (profound developmental delay, progressive microcephaly, and failure to thrive). The manifestation of all eight of these features has a specificity of 97%, and a sensitivity of 89% for the presence of an EPG5 mutation and will allow informed decisions about genetic testing. Clinical progression was relentless and many children died in infancy. Survival analysis demonstrated a median survival time of 24 months (95% confidence interval 0-49 months), with only a 10th of patients surviving to 5 years of age. Survival outcomes were significantly better in patients with compound heterozygous mutations (P = 0.046), as well as in patients with the recurrent p.Gln336Arg mutation. Acquired microcephaly and regression of skills in long-term survivors suggests a neurodegenerative component superimposed on the principal neurodevelopmental defect. Two-thirds of patients had a severe seizure disorder, placing EPG5 within the rapidly expanding group of genes associated with early-onset epileptic encephalopathies. Consistent neuroradiological features comprised structural abnormalities, in particular callosal agenesis and pontine hypoplasia, delayed myelination and, less frequently, thalamic signal intensity changes evolving over time. Typical muscle biopsy features included fibre size variability, central/internal nuclei, abnormal glycogen storage, presence of autophagic vacuoles and secondary mitochondrial abnormalities. Nerve biopsy performed in one case revealed subtotal absence of myelinated axons. Post-mortem examinations in three patients confirmed neurodevelopmental and neurodegenerative features and multisystem involvement. Finally, downregulation of epg5 (CG14299) in Drosophila resulted in autophagic abnormalities and progressive neurodegeneration. We conclude that EPG5-related Vici syndrome defines a novel group of neurodevelopmental disorders that should be considered in patients with suggestive features in whom mitochondrial, glycogen, or lysosomal storage disorders have been excluded. Neurological progression over time indicates an intriguing link between neurodevelopment and neurodegeneration, also supported by neurodegenerative features in epg5-deficient Drosophila, and recent implication of other autophagy regulators in late-onset neurodegenerative disease. © The Author (2016).

Leigh syndrome (LS) is the most common infantile mitochondrial encephalopathy. No treatment is currently available for this condition. Mice lacking Ndufs4, encoding NADH: ubiquinone oxidoreductase iron-sulfur protein 4 (NDUFS4) recapitulates the main findings of complex I (cI)-related LS, including severe multisystemic cI deficiency and progressive neurodegeneration. In order to develop a gene therapy approach for LS, we used here an AAV2/9 vector carrying the human NDUFS4 coding sequence (hNDUFS4). We administered AAV2/9-hNDUFS4 by intravenous (IV) and/or intracerebroventricular (ICV) routes to either newborn or young Ndufs4−/− mice. We found that IV administration alone was only able to correct the cI deficiency in peripheral organs, whereas ICV administration partially corrected the deficiency in the brain. However, both treatments failed to improve the clinical phenotype or to prolong the lifespan of Ndufs4−/− mice. In contrast, combined IV and ICV treatments resulted, along with increased cI activity, in the amelioration of the rotarod performance and in a significant prolongation of the lifespan. Our results indicate that extraneurological organs have an important role in LS pathogenesis and provide an insight into current limitations of adeno-associated virus (AAV)-mediated gene therapy in multisystem disorders. These findings warrant future investigations to develop new vectors able to efficiently target multiple organs. PMID:28753212

Pheochromocytoma multisystem crisis is a rare and life-threatening disease that is associated with numerous symptoms and which is also difficult to diagnose. We herein report an autopsy case of a 61-year-old man who died due to pheochromocytoma multisystem crisis. The patient complained of vomiting and breathlessness. Computed tomography showed a shadow-like region with a similar appearance to interstitial pneumonia. The patient was diagnosed with takotsubo cardiomyopathy induced by severe lung disease based on the results of echocardiography and coronary angiography. The patient was treated for interstitial pneumonia. However, his condition rapidly deteriorated and he died 6 hours after arrival. We were later informed of his extremely high catecholamine serum levels. We found pheochromocytoma with hemorrhage at autopsy. The patient's lungs showed acute passive congestion with edema and extravasation. PMID:28090043

Multisystemic Sarcoidosis Presenting as Pretibial Leg Ulcers.

Sarcoidosis is a multisystemic disease of unknown etiology. Up to 30% of patients develop cutaneous manifestations, either specific or nonspecific. Ulcerating sarcoidosis leading to leg ulcers is a rare observation that may lead to confusions with other, more common types of chronic leg ulcers. We report the case of a 45-year-old female patient with chronic multisystemic sarcoidosis presenting with pretibial leg ulcers. Other etiology could be excluded. Histology revealed nonspecific findings. Therefore, the diagnosis of nonspecific leg ulcers in sarcoidosis was confirmed. Treatment consisted of oral prednisolone and good ulcer care. Complete healing was achieved within 6 months. Sarcoidosis is a rare cause of leg ulcers and usually sarcoid granulomas can be found. Our patient illustrates that even in the absence of sarcoid granulomas, leg ulcers can be due to sarcoidosis. © The Author(s) 2016.

The purpose of this study was to evaluate whether orientation of a firearm predicts survival, and to identify risk factors associated with fatality in subjects with self-inflicted craniomaxillofacial gunshot wounds. A retrospective cohort study design was used. The primary predictor variable was orientation of the weapon, defined as in the coronal (lateral) or sagittal (anterior-posterior) trajectory pattern. The primary outcome variable was death for subjects on arrival or during their hospital stay. Other covariates measured include demographic, firearm-related, and psychosocial variables. Risk factors for fatality were identified using multivariate logistic regression. Of the 92 subjects that met study inclusion criteria, 47 (67.2) held the firearm in the coronal position. In the full multivariate model, coronal gun orientation (OR=7.7, 95% CI: 2.0, 30.1, p=0.003) and the absence of a psychiatric diagnosis were associated with an increased risk of fatality (OR=0.1, 95% CI: 0.04, 0.5, p=0.002). Coronal firearm orientation was associated with an increased risk of fatality following self-inflicted craniomaxillofacial gunshot injuries. A patient with a documented psychiatric disorder was not found to be more likely to succumb to this type of injury. Copyright © 2012 International Association of Oral and Maxillofacial Surgeons.

A counterfactual model was used to estimate the number of fatal opioid-related poisonings prevented by public treatment services for opioid use disorder (OUD) in England between April 2008 and March 2011. Patient OUD treatment episode data recorded by the English National Drug Treatment Monitoring System were linked to data on opioid deaths recorded by the Office for National Statistics. The source population was the official estimate of non-medical opioid users (aged 15-64 years; approximately 260 000 each year). The target population was all individuals (aged 15-64 years) treated for OUD in the study period (n = 220 665). The outcome measure was fatal opioid-related poisoning (opioid death). The opioid death rate [per 100 person-years (PY)] and mortality rate ratios (MRR) were computed for study year, age group (15-24, 25-34, 35-64 years) and for three treatment-related states: time spent 'prior to treatment', 'during treatment' and 'after treatment'. Between April 2008 and March 2011, there were 3731 opioid deaths in the study: 741 during treatment (0.20 per 100 PY; referent category); 2722 prior to treatment [0.77 per 100 PY; MRR = 3.76, 95% confidence interval (CI) = 3.18-4.44]; and 268 after treatment (0.41 per 100 PY; MRR = 1.99, 95% CI = 1.64-2.41). By counterfactual estimation, national OUD treatment services prevented an average of 880 opioid deaths each year (95% CI = 702-1084). Between April 2008 and March 2011, a counterfactual model shows that the English public treatment system for opioid use disorder prevented an average of 880 deaths each year from opioid-related poisoning. Counterfactual models of mortality prevention can be used for outcome and performance monitoring of substance use disorder treatment systems. © 2015 Society for the Study of Addiction.

Non-fatal health outcomes from diseases and injuries are a crucial consideration in the promotion and monitoring of individual and population health. The Global Burden of Disease (GBD) studies done in 1990 and 2000 have been the only studies to quantify non-fatal health outcomes across an exhaustive set of disorders at the global and regional level. Neither effort quantified uncertainty in prevalence or years lived with disability (YLDs). Of the 291 diseases and injuries in the GBD cause list, 289 cause disability. For 1160 sequelae of the 289 diseases and injuries, we undertook a systematic analysis of prevalence, incidence, remission, duration, and excess mortality. Sources included published studies, case notification, population-based cancer registries, other disease registries, antenatal clinic serosurveillance, hospital discharge data, ambulatory care data, household surveys, other surveys, and cohort studies. For most sequelae, we used a Bayesian meta-regression method, DisMod-MR, designed to address key limitations in descriptive epidemiological data, including missing data, inconsistency, and large methodological variation between data sources. For some disorders, we used natural history models, geospatial models, back-calculation models (models calculating incidence from population mortality rates and case fatality), or registration completeness models (models adjusting for incomplete registration with health-system access and other covariates). Disability weights for 220 unique health states were used to capture the severity of health loss. YLDs by cause at age, sex, country, and year levels were adjusted for comorbidity with simulation methods. We included uncertainty estimates at all stages of the analysis. Global prevalence for all ages combined in 2010 across the 1160 sequelae ranged from fewer than one case per 1 million people to 350,000 cases per 1 million people. Prevalence and severity of health loss were weakly correlated (correlation coefficient -0·37). In 2010, there were 777 million YLDs from all causes, up from 583 million in 1990. The main contributors to global YLDs were mental and behavioural disorders, musculoskeletal disorders, and diabetes or endocrine diseases. The leading specific causes of YLDs were much the same in 2010 as they were in 1990: low back pain, major depressive disorder, iron-deficiency anaemia, neck pain, chronic obstructive pulmonary disease, anxiety disorders, migraine, diabetes, and falls. Age-specific prevalence of YLDs increased with age in all regions and has decreased slightly from 1990 to 2010. Regional patterns of the leading causes of YLDs were more similar compared with years of life lost due to premature mortality. Neglected tropical diseases, HIV/AIDS, tuberculosis, malaria, and anaemia were important causes of YLDs in sub-Saharan Africa. Rates of YLDs per 100,000 people have remained largely constant over time but rise steadily with age. Population growth and ageing have increased YLD numbers and crude rates over the past two decades. Prevalences of the most common causes of YLDs, such as mental and behavioural disorders and musculoskeletal disorders, have not decreased. Health systems will need to address the needs of the rising numbers of individuals with a range of disorders that largely cause disability but not mortality. Quantification of the burden of non-fatal health outcomes will be crucial to understand how well health systems are responding to these challenges. Effective and affordable strategies to deal with this rising burden are an urgent priority for health systems in most parts of the world. Bill & Melinda Gates Foundation.

Acute fatal metabolic complications in alkaptonuria.

PubMed

Davison, A S; Milan, A M; Gallagher, J A; Ranganath, L R

2016-03-01

Alkaptonuria (AKU) is a rare inherited metabolic disorder of tyrosine metabolism that results from a defect in an enzyme called homogentisate 1,2-dioxygenase. The result of this is that homogentisic acid (HGA) accumulates in the body. HGA is central to the pathophysiology of this disease and the consequences observed; these include spondyloarthropathy, rupture of ligaments/muscle/tendons, valvular heart disease including aortic stenosis and renal stones. While AKU is considered to be a chronic progressive disorder, it is clear from published case reports that fatal acute metabolic complications can also occur. These include oxidative haemolysis and methaemoglobinaemia. The exact mechanisms underlying the latter are not clear, but it is proposed that disordered metabolism within the red blood cell is responsible for favouring a pro-oxidant environment that leads to the life threatening complications observed. Herein the role of red blood cell in maintaining the redox state of the body is reviewed in the context of AKU. In addition previously reported therapeutic strategies are discussed, specifically with respect to why reported treatments had little therapeutic effect. The potential use of nitisinone for the management of patients suffering from the acute metabolic decompensation in AKU is proposed as an alternative strategy.

Cytophagic histiocytic panniculitis and hemophagocytic lymphohistiocytosis: an overview.

PubMed

Aronson, Iris K; Worobec, Sophie M

2010-01-01

Cytophagic histiocytic panniculitis (CHP) is a rare panniculitis that is associated with systemic features including fevers, hepatosplenomegaly, lymphadenopathy, pancytopenia, hepatic abnormalities, hypertriglyceridemia, and coagulopathy without an elevated erythrocyte sedimentation rate. The panniculitis lesions show adipose tissue lymphocytic and histiocytic infiltration along with hemophagocytosis, which may also appear in bone marrow, spleen, lymph nodes, and liver. Patients may have a rapidly fatal disease course, a longer disease course with intermittent remissions and exacerbations for many years prior to death, or a nonfatal acute or intermittent course responsive to treatment. The cytophagocytic disorder in these patients is a hemophagocytic lymphohistiocytosis (HLH), similar to the infection-activated reaction associated with perforin mutations found in familial hemophagocytic lymphohistiocytosis. HLH is a group of autoinflammatory disorders, which include macrophage activation syndrome and infection-associated hemophagocytic syndrome, which if not treated rapidly, can be fatal. The relationship of CHP and HLH is discussed. CHP associated diseases include: subcutaneous panniculitis-like T cell lymphomas; infections, connective tissue diseases, other malignancies, and the molecular disorders that cause HLH. Treatment of CHP includes: glucocorticoids in combination with cyclosporine, combined chemotherapeutic medications and most recently, anakinra, an Interleukin-1 receptor antagonist; along with supportive care, search for underlying malignancies and treatment thereof, and control of associated infections.

Making psychiatric semiology great again: A semiologic, not nosologic challenge.

This article analyzes whether psychiatric disorders can be considered different from non-psychiatric disorders on a nosologic or semiologic point of view. The supposed difference between psychiatric and non-psychiatric disorders relates to the fact that the individuation of psychiatric disorders seems more complex than for non-psychiatric disorders. This individuation process can be related to nosologic and semiologic considerations. The first part of the article analyzes whether the ways of constructing classifications of psychiatric disorders are different than for non-psychiatric disorders. The ways of establishing the boundaries between the normal and the pathologic, and of classifying the signs and symptoms in different categories of disorder, are analyzed. Rather than highlighting the specificity of psychiatric disorders, nosologic investigation reveals conceptual notions that apply to the entire field of medicine when we seek to establish the boundaries between the normal and the pathologic and between different disorders. Psychiatry is thus very important in medicine because it exemplifies the inherent problem of the construction of cognitive schemes imposed on clinical and scientific medical information to delineate a classification of disorders and increase its comprehensibility and utility. The second part of this article assesses whether the clinical manifestations of psychiatric disorders (semiology) are specific to the point that they are entities that are different from non-psychiatric disorders. The attribution of clinical manifestations in the different classifications (Research Diagnostic Criteria, Diagnostic Statistic Manual, Research Domain Criteria) is analyzed. Then the two principal models on signs and symptoms, i.e. the latent variable model and the causal network model, are assessed. Unlike nosologic investigation, semiologic analysis is able to reveal specific psychiatric features in a patient. The challenge, therefore, is to better define and classify signs and symptoms in psychiatry based on a dual and mutually interactive biological and psychological perspective, and to incorporate semiologic psychiatry into an integrative, multilevel and multisystem brain and cognitive approach.

Beaudin, Marie; Klein, Christopher J; Rouleau, Guy A; Dupré, Nicolas

2017-01-01

The classification of autosomal recessive ataxias represents a significant challenge because of high genetic heterogeneity and complex phenotypes. We conducted a comprehensive systematic review of the literature to examine all recessive ataxias in order to propose a new classification and properly circumscribe this field as new technologies are emerging for comprehensive targeted gene testing. We searched Pubmed and Embase to identify original articles on recessive forms of ataxia in humans for which a causative gene had been identified. Reference lists and public databases, including OMIM and GeneReviews, were also reviewed. We evaluated the clinical descriptions to determine if ataxia was a core feature of the phenotype and assessed the available evidence on the genotype-phenotype association. Included disorders were classified as primary recessive ataxias, as other complex movement or multisystem disorders with prominent ataxia, or as disorders that may occasionally present with ataxia. After removal of duplicates, 2354 references were reviewed and assessed for inclusion. A total of 130 articles were completely reviewed and included in this qualitative analysis. The proposed new list of autosomal recessive ataxias includes 45 gene-defined disorders for which ataxia is a core presenting feature. We propose a clinical algorithm based on the associated symptoms. We present a new classification for autosomal recessive ataxias that brings awareness to their complex phenotypes while providing a unified categorization of this group of disorders. This review should assist in the development of a consensus nomenclature useful in both clinical and research applications.

2016-02-01

Attempted or non-fatal self-poisoning in common in Sri Lanka, but little is known about variation of psychiatric morbidity and suicidal intent across differing ages. The aim of this study was to investigate factors associated with non-fatal self-poisoning in Sri Lanka across three different age groups (namely 14-24 years, 25-34 years and ≥ 35 years). It was anticipated that the findings of the study would inform and guide development of preventive interventions for non-fatal self-poisoning in this country. 935 participants were interviewed within one week of admission to hospital for medical management of non-fatal self-poisoning, over a consecutive 14-month period. Socio-demographic factors, types of poison ingested, triggers and psychiatric morbidity was examined as a function of age. Results showed that a majority (83%) of participants were aged below 35 years. Younger participants aged <25 years were significantly more likely to ingest medicinal overdoses, compared to older persons (aged 25-34 years, and ≥ 35 years), who were more likely to ingest pesticides. Recent interpersonal conflict was a proximal trigger seen in all age groups, but suicidal intent, depression and alcohol use disorders increased with age. The overall study findings indicate that most who carry out acts of non-fatal self-poisoning in Sri Lanka are young (aged <35 years). Interpersonal conflict as a trigger is common to all age groups, but psychiatric morbidity and suicidal intent is higher in the older age groups, as is pesticide ingestion. Age specific interventions may be efficacious in the prevention of non-fatal self-poisoning in Sri Lanka. Copyright © 2016 Elsevier B.V. All rights reserved.

Major depression is the leading cause of non-fatal disease burden. Because major depression is not a homogeneous condition, this study estimated the non-fatal disease burden for mild, moderate and severe depression in both single episode and recurrent depression. All estimates were assessed from an individual and a population perspective and presented as unadjusted, raw estimates and as estimates adjusted for comorbidity. We used data from the first wave of the second Netherlands-Mental-Health-Survey-and-Incidence-Study (NEMESIS-2, n = 6646; single episode Diagnostic and Statistical Manual (DSM)-IV depression, n = 115; recurrent depression, n = 246). Disease burden from an individual perspective was assessed as 'disability weight * time spent in depression' for each person in the dataset. From a population perspective it was assessed as 'disability weight * time spent in depression *number of people affected'. The presence of mental disorders was assessed with the Composite International Diagnostic Interview (CIDI) 3.0. Single depressive episodes emerged as a key driver of disease burden from an individual perspective. From a population perspective, recurrent depressions emerged as a key driver. These findings remained unaltered after adjusting for comorbidity. The burden of disease differs between the subtype of depression and depends much on the choice of perspective. The distinction between an individual and a population perspective may help to avoid misunderstandings between policy makers and clinicians.

Celiac disease is a multi-system disorder with manifestations that may result in psychiatric disorders. We assessed the prevalence of medication use to treat psychiatric disorders in celiac disease patients. We conducted a cross-sectional study of patients undergoing esophagogastroduodenoscopy over 9-years at a celiac disease referral center. We compared the prevalence of psychotropic medication use among celiac disease patients (n = 1293) to a control group (n = 1401) with abdominal pain or reflux. Among all patients the mean age was 48.4 years, most were female (69.5%), and 22.7% used any psychotropic medication. There was no difference between overall psychotropic medication use among celiac disease patients and controls (23.9% vs 21.8%, OR 1.16; 95% CI 0.96-1.39, p = 0.12). However, those with celiac disease were more likely to use antidepressants on univariate (16.4% vs 13.4%, p = 0.03) and multivariate analysis (OR 1.28; 95% CI 1.03-1.59; p = 0.03). Use of psychotropic medications was not associated with disease duration or mode of presentation of celiac disease. Celiac disease patients use psychotropic medications at similar rates as those with other gastrointestinal diseases, though subgroup analysis suggests they may use more antidepressants. Future studies should investigate whether celiac disease is associated with mood disorders that are not treated with medications.

Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem.

Vascular type Ehlers-Danlos Syndrome with fatal spontaneous rupture of a right common iliac artery dissection: case report and review of literature

2014-01-01

Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation). The vascular type accounts for less than 4% of all Ehlers-Danlos cases and usually has a poor prognosis due to life threatening vascular ruptures and difficult, frequently unsuccessful surgical and vascular interventions. In 70% of cases, vascular rupture or dissection, gastrointestinal perforation, or organ rupture is a presenting sign. We present a case of genetically proven vascular Ehlers-Danlos with fatal recurrent retroperitoneal hemorrhages secondary to a ruptured right common iliac artery dissection in a 30-year-old male. This case highlights the need to suspect collagen vascular disorders when a young adult presents with unexplained retroperitoneal hemorrhage, even without family history of such diseases.

Autism in the Son of a Woman with Mitochondrial Myopathy and Dysautonomia: A Case Report.

Brown, Bradley D; Rais, Theodore

2015-01-01

The relationship between autism spectrum disorders and mitochondrial dysfunction, including mitochondrial myopathies and other mitochondrial diseases, is an area of ongoing research. All autism spectrum disorders are known to be heritable, via genetic and/or epigenetic mechanisms, but specific modes of inheritance are not well characterized. Nevertheless, autism spectrum disorders have been linked to many specific genes associated with mitochondrial function, especially to genes involved in mitochondrial tRNA and the electron transport chain, both particularly vulnerable to point mutations, and clinical research also supports a relationship between the two pathologies. Although only a small minority of patients with autism have a mitochondrial disease, many patients with mitochondrial myopathies have autism spectrum disorder symptoms, and these symptoms may be the presenting symptoms, which presents a diagnostic challenge for clinicians. The authors report the case of a 15-year-old boy with a history of autism spectrum disorder and neurocardiogenic syncope, admitted to the inpatient unit for self-injury, whose young mother, age 35, was discovered to suffer from mitochondrial myopathy, dysautonomia, neurocardiogenic syncope, Ehler-Danlos syndrome, and other uncommon multisystem pathologies likely related to mitochondrial dysfunction. This case illustrates the need for a high index of suspicion for mitochondrial disease in patients with autism, as they have two orders of magnitude greater risk for such diseases than the general population. The literature shows that mitochondrial disease is underdiagnosed in autism spectrum disorder patients and should not be viewed as a "zebra" (i.e., an obscure diagnosis that is made when a more common explanation is more likely).

Work-related musculoskeletal disorders (MSDs) are most commonly seen in all the occupational non-fatal injuries and illnesses for workers, especially those who are involved in labor-intensive industries. Participatory ergonomics is frequently used to prevent musculoskeletal disorders. This paper gives an overview of a historical perspective on the use of participatory ergonomics approach in reducing the health effects of labor-intensive industries. Progress, barriers and facilitators on the organization, implementation and evaluation of participatory ergonomics programs are studied. Participatory ergonomics seems a successful method to develop, prioritize measures to prevent MSDs. Participatory ergonomics can help industries reduce musculoskeletal injuries and disorders, improve workplace condition and promote health conditions of the workers.

Natural killer (NK) lymphoma in Asia is frequently associated with latent Epstein-Barr (EBV) infection. Unlike the adult cases, EBV-associated NK/T cell lymphomas in children are often preceded by various EBV-related disorders, including chronic active EBV infection (CAEBV), hypersensitivity to mosquito bites (HMB), virus-associated haemophagocytic syndrome (VAHS), and hydroa vacciniforme (HV)-like eruptions. Here, we report a 14-year-old Japanese girl who sequentially developed all the symptoms related to EBV-associated NK/T cell lymphoproliferative disorders in a 12-year clinical course. Our observations confirm the spectrum of EBV-associated cutaneous disorders and indicate the importance of long-term follow-up.

[Therapeutic update in tuberous sclerosis complex: the role of mTOR pathway inhibitors].

PubMed

Ruiz-Falcó Rojas, M Luz

2012-05-21

Tuberous sclerosis complex is an autosomal dominant disease, with variable expressivity and multisystemic involvement, which is characterised by the growth of benign tumours called hamartomas. The organs that are most commonly affected are the brain, skin, kidneys, eyes, heart and lungs. Of all the children with this disease, 85% present neurological manifestations that, due to their severity, are the main cause of morbidity and mortality. The most significant neurological manifestations are epilepsy, autism spectrum disorders and mental retardation. It has been shown that in tuberous sclerosis complex the genes TSC1 and TSC2 alter the mTOR enzyme cascade, which sets off inhibition of this pathway. The possibility of resorting to treatments applied at the origin, thus inhibiting this pathway, is currently being evaluated.

Adamantiades-Behçet's disease is a multisystemic vasculitis with multiorgan involvement. Ocular disorders occur often in this syndrome typically in the form of a relapsing-remitting panuveitis and vasculitis and can lead to blindness as one of its most disabling complications if left untreated. There are known risk factors related with the worst visual prognosis, which require early and intensive treatment in order to obtain a rapid suppression of inflammation and to prevent future relapses. The management strategy to avoid vision loss and blindness currently involves the use of local and systemic drugs including steroids and immunosuppressive and biologic agents. This review aims to demonstrate how the introduction and the use of biologic agents improves the visual outcome of patients with Adamantiades-Behçet's disease. PMID:26558256

Peri-procedural risk stratification and management of patients with Williams syndrome.

2017-03-01

Williams syndrome (WS) is a congenital, multisystem disorder affecting the cardiovascular, connective tissue, and central nervous systems in 1 in 10 000 live births. Cardiovascular involvement is the most common cause of morbidity and mortality in patients with WS, and noninvasive and invasive procedures are common. Sudden cardiovascular collapse in patients with WS is a well-known phenomenon, especially in the peri-procedural period. Detailed guidelines for peri-procedural management of patients with WS are limited. The goal of this review is to provide thoughtful, safe and effective management strategies for the peri-procedural care of patients with WS with careful consideration of hemodynamic impacts of anesthetic strategies. In addition, an expanded risk stratification system for anesthetic administration is provided. © 2017 Wiley Periodicals, Inc.

We present two siblings with identical clinical findings that seem to represent a previously unreported familial syndrome. Major findings involve three systems: pulmonary arterial hypertension, cardiac abnormalities including secundum-type atrial septal defect, and the hematopoietic system with intermittent neutropenia, lymphopenia, monocytosis, and anemia. The siblings also shared several minor abnormalities: pectus carinatum, long fingers, proximally placed thumb, broad nasal bridge, and high-arched palate. The male proband also had bilateral inguinal hernias and undescended testes. The same findings in two siblings suggest a genetic cause--either an autosomal recessive disorder or germline mosaicism in one parent for a dominant mutation. Investigations revealed a bone morphogenetic protein receptor 2 polymorphism in intron 4 in only one sibling, which was also present in unaffected maternal relatives.

Fabry disease (FD) is an X-linked lysosomal storage disorder that affects both men and women. The manifestations of this heterogeneous disease are multisystemic and progressive. Prior to the development of enzyme replacement therapy, the management and treatment for Fabry disease was largely nonspecific and supportive. Because enzyme replacement therapy became commercially available in 2001, a variety of clinical benefits in Fabry patients have been consistently reported, including improved renal pathology and cardiac function, and reduced severity of neuropathic pain and improved pain-related quality of life. This update focuses on published data on the efficacy and tolerability of enzyme replacement therapy with agalsidase alfa, and gives a brief overview on some of the outstanding management issues in the treatment of this complex disease.

McCann, Liza J; Pain, Clare E

2016-02-01

Juvenile dermatomyositis and juvenile scleroderma are rare multisystem autoimmune disorders. Although they share some pathognomonic hallmarks with adult onset myositis or scleroderma, there are significant differences in presentation, characteristics and associated features when the diseases present in childhood. In view of this, and the rarity of the conditions, it is important for care to be led by teams with expertise in pediatric rheumatology conditions. Prognosis has improved significantly in the West; likely due to early diagnosis and aggressive treatment with immunosuppressive medications. However, this trend is not replicated in the developing world. Early recognition of these diseases is crucial to achieve rapid and sustained remission and prevent disease or medication associated complications. This article aims to provide a practical overview for recognition, diagnosis and treatment of these conditions.

Current Perspectives on Physical Activity and Exercise Recommendations for Children and Adolescents With Autism Spectrum Disorders

PubMed Central

Srinivasan, Sudha M.; Pescatello, Linda S.

2014-01-01

Recent evidence suggests that childhood obesity is increasing in children who are developing typically as well as in children with developmental disabilities such as autism spectrum disorders (ASDs). Impairments specific to autism as well as general environmental factors could lead to an imbalance between the intake and expenditure of energy, leading to obesity. In this article, we describe the mechanisms by which autism-specific impairments contribute to obesity. The evidence on exercise interventions to improve physical fitness, address obesity, and reduce autism-specific impairments in children and adolescents with ASDs is discussed. Limited evidence is currently available for exercise interventions in individuals with ASDs. Therefore, literature on other pediatric developmental disabilities and children who are developing typically was reviewed to provide recommendations for clinicians to assess physical activity levels, to promote physical fitness, and to reduce obesity in children and adolescents with ASDs. There is a clear need for further systematic research to develop sensitive assessment tools and holistic multisystem and multifactorial obesity interventions that accommodate the social communication, motor, and behavioral impairments of individuals with ASDs.

Canakinumab for the treatment of cryopyrin-associated periodic syndromes.

PubMed

Walsh, Garry M

2009-10-01

Familial cold-induced autoinflammatory syndrome, Muckle-Wells syndrome and neonatal-onset multisystem inflammatory disease make up cryopyrin-associated periodic syndromes (CAPS). These are autoinflammatory inherited disorders caused by autosomal dominant gain-of-function mutations in the NLRP3 gene, located on chromosome 1q44. Cryopyrin/NALP3/NLRP3 is an essential component of intracellular inflammasomes that activate caspase-1, which in turn converts interleukin-1beta (IL-1beta) to its active form. IL-1beta is a potent cytokine that activates diverse elements of the immune and inflammatory systems leading to the pathogenic changes characteristic of CAPS. There is therefore much interest in the development of IL-1beta blocking agents as novel biologic treatments for these conditions. Canakinumab (ACZ-885; Ilaris, Novartis Pharma) is a fully humanized monoclonal antibody (mAb) specific for IL-1beta and is indicated for a wide range of inflammatory disorders including CAPS. This review will assess the utility of canakinumab as a treatment for CAPS. Copyright 2009 Prous Science, S.A.U. or its licensors. All rights reserved.

[A literature review of Norrie disease].

PubMed

Ohba, N; Isashiki, Y

1996-02-01

Norrie disease is a rare genetic disorder characterized by bilateral congenital blindness. The salient clinical feature early in life is a dense, white, vascularized mass behind each lens due to maldeveloped retina. Cataracts and corneal opacities are developed in young childhood, followed by bulbar atrophies. Histopathologic examination suggests primary vitreoretinal dysplasia because of developmental arrest of the retina in the middle embryonic stage. Occasional patients show psychomotor retardation or progressive hearing loss as part of a multisystem disorder. The disease is transmitted by an X-linked recessive form of inheritance, with sons of female carriers having a 50% risk for expressing the disease. In recent years, a candidate gene for Norrie disease has been isolated and characterized, which encompasses 27 kilobases and consists of three exons interspersed by two introns. Microdeletions and a variety of point mutations in the disease gene were identified in Norrie patients, although the genotype-phenotype correlation remains to be defined, and molecular diagnosis is now available for Norrie disease. The encoded protein has homology to a protein domain involving mucins and TGF beta, which may play an essential role in targeting of retinal/neural connections.

A 14-year-old girl, whose birth and developmental history were normal till the age of 7, was admitted to our hospital because of slowly progressive difficulties in walking, speaking and hearing. She also complained of absence of menstruation. She showed poor school records since the age of 7. On neurological examination, she showed limb and truncal ataxia. There was no nystagmus but slurred speech was found. Muscular power was good and her sensory system was normal. Tendon reflexes were equally present, and plantar reflexes were flexor. Bilateral moderate nerve deafness was also present. Mental deficiency was diagnosed on an intelligence test. Brain CT and MRI showed cerebellar atrophy. Gynecological examination revealed scanty pubic hair and small uterus. Karyotype was 46XX. Endocrinological studies demonstrated high level of FSH, low level of E2, and the normal response to pituitary stimulation with LHRH, indicating the existence of primary hypogonadism. Although the etiology of this multisystem disorder is unknown, it is possible that both nervous and endocrine disorders were genetically determined.

2011-12-01

We present the case of a 31-year-old woman with Ehler-Danlos syndrome (EDS) type 2. She had a previous caesarean section and went on to have an uncomplicated vaginal birth in her last pregnancy. To our knowledge, this is the first case of a successful vaginal birth after caesarean section in a patient with EDS. EDS is a multisystem disorder involving a genetic defect in collagen and connective-tissue synthesis and structure. It is a heterogeneous group of 11 different inherited disorders. Obstetric complications in these patients include miscarriages, stillbirths, premature rupture of the membranes, preterm labour, uterine prolapse, uterine rupture and severe postpartum haemorrhage. There has been much controversy over the appropriate mode of delivery. Abdominal deliveries are complicated by delayed wound healing and increased perioperative blood loss. Vaginal deliveries may be complicated by tissue friability causing extensive perineal tears, pelvic floor and bladder lesions. Our case highlights that in specific, controlled situations it is possible to have a vaginal delivery even after previous caesarean section in patients with EDS.

Among the range of sleep-related behavior displayed by patients with rapid eye movement (REM) sleep behavior disorder (RBD), aggressive acts are particularly common, while pleasant behaviors have rarely been reported. We aimed at identifying the frequency and characteristics of patients who displayed laughing as a pleasant, nonviolent manifestation of RBD. We reviewed 67 consecutive polysomnographic recordings of patients with RBD, obtained in our sleep laboratory between July 2004 and July 2009. We identified 14 patients (21% of our RBD patients with degenerative parkinsonism: 10 males, mean age 63 ± 11 years) who repeatedly laughed during REM sleep. Ten patients had idiopathic Parkinson's disease, 3 suffered from multisystem atrophy and 1 patient was diagnosed with dementia with Lewy bodies. Other RBD-associated behaviors included smiling, crying, aggressive behavior, screaming, and somniloquia. Nine of the 14 patients were depressed during daytime. Laughing belongs to the spectrum of behavioral manifestations of RBD. Many of our patients with RBD-associated laughter were depressed, suggesting a dissociation between emotional expression during daytime and REM sleep. Copyright © 2011 Elsevier Ltd.

Sarcoidosis is a systemic granulomatous disorder of unidentified etiology, with a heterogeneous clinical presentation. It is characterized by a reduced delayed-type hypersensitivity to tuberculin and common antigens. The balance between Th1, Th17 and Regulatory T(Treg) cells controls T-cell proliferation and activation.The Th17/Treg ratio in the peripheral blood and bronchoalveolar lavage fluidis increased in patients with active sarcoidosis. Amplified IL-17A expression in granulomas and the presence of IL-17A+, IL-17A+IL-4+ and IL-17A+IFN-γ+ memory T helper cells in the circulation and BAL indicate Th17 cell involvement in granuloma induction and/or maintenance in sarcoidosis. Sarcoidosis should therefore be considered as a Th1/Th17 multisystem disorder and anti-IL-17/Th17 approaches that control and reduce IL-17Amay be an option, therefore, for the treatment of sarcoidosis.Here we provide a short overview as to the role of Th17 cells as critical cells in the pathogenesis of sarcoidosis.

Novel Directions for Diabetes Mellitus Drug Discovery

Maiese, Kenneth; Chong, Zhao Zhong; Shang, Yan Chen; Wang, Shaohui

2012-01-01

Introduction Diabetes mellitus impacts almost 200 million individuals worldwide and leads to debilitating complications. New avenues of drug discovery must target the underlying cellular processes of oxidative stress, apoptosis, autophagy, and inflammation that can mediate multi-system pathology during diabetes mellitus. Areas Covered We examine novel directions for drug discovery that involve the β-nicotinamide adenine dinucleotide (NAD+) precursor nicotinamide, the cytokine erythropoietin, the NAD+-dependent protein histone deacetylase SIRT1, the serine/threonine-protein kinase mammalian target of rapamycin (mTOR), and the wingless pathway. Implications for the targeting of these pathways that oversee gluconeogenic genes, insulin signaling and resistance, fatty acid beta-oxidation, inflammation, and cellular survival are presented. Expert Opinion Nicotinamide, erythropoietin, and the downstram pathways of SIRT1, mTOR, forkhead transcription factors, and wingless signaling offer exciting prospects for novel directions of drug discovery for the treatment of metabolic disorders. Future investigations must dissect the complex relationship and fine modulation of these pathways for the successful translation of robust reparative and regenerative strategies against diabetes mellitus and the complications of this disorder.

Pseudoxanthoma elasticum is a metabolic disease.

2009-02-01

Pseudoxanthoma elasticum (PXE) is a pleiotropic multisystem disorder affecting skin, eyes, and the cardiovascular system with progressive pathological mineralization. It is caused by mutations in the ABCC6 gene expressed primarily in the liver and kidneys, and at very low levels, if at all, in tissues affected by PXE. A question has arisen regarding the pathomechanism of PXE, particularly the "metabolic" versus the "PXE cell" hypotheses. We examined a murine PXE model (Abcc6(-/-)) by transplanting muzzle skin from knockout (KO) and wild-type (WT) mice onto the back of WT and KO mice using mineralization of the connective tissue capsule surrounding the vibrissae as an early phenotypic biomarker. Grafting of WT mouse muzzle skin onto the back of KO mice resulted in mineralization of vibrissae, whereas grafting KO mouse muzzle skin onto WT mice did not. Thus, these findings implicate circulatory factors as a critical component of the mineralization process. This mouse grafting model supports the notion that PXE is a systemic metabolic disorder with secondary mineralization of connective tissues and that the mineralization process can be countered or even reversed by changes in the homeostatic milieu.

Human babesiosis is a tick-borne multisystem disease caused by Babesia species of the apicomplexan phylum. Most clinical cases and fatalities of babesiosis are caused by Babesia microti. Current treatment for human babesiosis consists of two drug combinations, atovaquone + azithromycin or quinine + clindamycin. These treatments are associated with adverse side effects and a significant rate of drug failure. Here, we provide evidence for radical cure of experimental babesiosis in immunodeficient mice using a combination of an endochin-like quinolone (ELQ) prodrug and atovaquone. In vivo efficacy studies in mice using ELQ-271, ELQ-316, and the ELQ-316 prodrug, ELQ-334, demonstrated excellent growth inhibitory activity against the parasite, with potency equal to that of orally administered atovaquone at 10 mg/kg. Analysis of recrudescent parasites after ELQ or atovaquone monotherapy identified genetic substitutions in the Qi or Qo sites, respectively, of the cytochrome bc1 complex. Impressively, a combination of ELQ-334 and atovaquone, at doses as low as 5.0 mg/kg each, resulted in complete clearance of the parasite with no recrudescence up to 122 d after discontinuation of therapy. These results will set the stage for future clinical evaluation of ELQ and atovaquone combination therapy for treatment of human babesiosis. PMID:27270894

A captive 8 yr old male bottlenose dolphin Tursiops truncatus succumbed to septicemia with multisystemic inflammation including suppurative enteritis, encephalitis, and pneumonia with chronic pancreatitis. A pure culture of beta-hemolytic, catalase- and oxidase-negative, Gram-positive cocci was isolated from the hilar lymph nodes and pancreas. The isolate was identified by 16S rDNA sequencing as Streptococcus iniae. Histological examination of the digestive system revealed a mixed infection of both bacteria and fungus. Recognized as a pathogen in fish, dolphins, and humans, this is the first report of S. iniae in a dolphin in mainland China. As the number of managed animals in oceanariums is increasing, so is the frequency of contact with fish used as food for marine mammals and humans, highlighting the importance of education and appropriate personal protective protocols to minimize the risk of transmission. An understanding of marine mammal infectious disease organisms is essential to ensuring the health of marine mammals and humans coming into contact with such animals and their food. This study illustrates a systematic clinical, microbiological, and pathological investigation into a septicemic bottlenose dolphin infected with S. iniae. Our findings provide useful information for those involved in the diagnosis and control of infectious diseases in marine mammals and offer insight into an important zoonotic pathogen.

Nipah virus is a broadly tropic and highly pathogenic zoonotic paramyxovirus in the genus Henipavirus whose natural reservoirs are several species of Pteropus fruit bats. Nipah virus has repeatedly caused outbreaks over the past decade associated with a severe and often fatal disease in humans and animals. Here, a new ferret model of Nipah virus pathogenesis is described where both respiratory and neurological disease are present in infected animals. Severe disease occurs with viral doses as low as 500 TCID(50) within 6 to 10 days following infection. The underlying pathology seen in the ferret closely resembles that seen in Nipah virus infected humans, characterized as a widespread multisystemic vasculitis, with virus replicating in highly vascular tissues including lung, spleen and brain, with recoverable virus from a variety of tissues. Using this ferret model a cross-reactive neutralizing human monoclonal antibody, m102.4, targeting the henipavirus G glycoprotein was evaluated in vivo as a potential therapeutic agent. All ferrets that received m102.4 ten hours following a high dose oral-nasal Nipah virus challenge were protected from disease while all controls died. This study is the first successful post-exposure passive antibody therapy for Nipah virus using a human monoclonal antibody.

Risk groups for yellow fever vaccine-associated viscerotropic disease (YEL-AVD).

PubMed

Seligman, Stephen J

2014-10-07

Although previously considered as the safest of the live virus vaccines, reports published since 2001 indicate that live yellow fever virus vaccine can cause a severe, often fatal, multisystemic illness, yellow fever vaccine-associated viscerotropic disease (YEL-AVD), that resembles the disease it was designed to prevent. This review was prompted by the availability of a listing of the cumulative cases of YEL-AVD, insights from a statistical method for analyzing risk factors and re-evaluation of previously published data. The purpose of this review is to identify and analyze risk groups based on gender, age, outcome and predisposing illnesses. Using a passive surveillance system in the US, the incidence was reported as 0.3 to 0.4 cases per 100,000. However, other estimates range from 0 to 12 per 100,000. Identified and potential risk groups for YEL-AVD include elderly males, women between the ages of 19 and 34, people with a variety of autoimmune diseases, individuals who have been thymectomized because of thymoma, and infants and children ≤11 years old. All but the last group are supported by statistical analysis. The confirmed risk groups account for 77% (49/64) of known cases and 76% (32/42) of the deaths. The overall case fatality rate is 66% (42/64) with a rate of 80% (12/15) in young women, in contrast to 50% (13/26) in men ≥56 years old. Recognition of YEL-AVD raises the possibility that similar reactions to live chimeric flavivirus vaccines that contain a yellow fever virus vaccine backbone could occur in susceptible individuals. Delineation of risk groups focuses the search for genetic mutations resulting in immune defects associated with a given risk group. Lastly, identification of risk groups encourages concentration on measures to decrease both the incidence and the severity of YEL-AVD. Copyright © 2014 Elsevier Ltd. All rights reserved.

Optimizing Parkinson's disease diagnosis: the role of a dual nuclear imaging algorithm.

PubMed

Langston, J William; Wiley, Jesse C; Tagliati, Michele

2018-01-01

The diagnosis of Parkinson's disease (PD) currently relies almost exclusively on the clinical judgment of an experienced neurologist, ideally a specialist in movement disorders. However, such clinical diagnosis is often incorrect in a large percentage of patients, particularly in the early stages of the disease. A commercially available, objective and quantitative marker of nigrostriatal neurodegeneration was recently provided by 123-iodine 123 I-ioflupane SPECT imaging, which is however unable to differentiate PD from a variety of other parkinsonian syndromes associated with striatal dopamine deficiency. There is evidence to support an algorithm utilizing a dual neuroimaging strategy combining 123 I-ioflupane SPECT and the noradrenergic receptor ligand 123 I-metaiodobenzylguanidine (MIBG), which assesses the post-ganglion peripheral autonomic nervous system. Evolving concepts regarding the synucleinopathy affecting the central and peripheral autonomic nervous systems as part of a multisystem disease are reviewed to sustain such strategy. Data are presented to show how MIBG deficits are a common feature of multisystem Lewy body disease and can be used as a unique feature to distinguish PD from atypical parkinsonisms. We propose that the combination of cardiac (MIBG) and cerebral 123 I-ioflupane SPECT could satisfy one of the most significant unmet needs of current PD diagnosis and management, namely the early and accurate diagnosis of patients with typical Lewy body PD. Exemplary case scenarios will be described, highlighting how dual neuroimaging strategy can maximize diagnostic accuracy for patient care, clinical trials, pre-symptomatic PD screening, and special cases provided by specific genetic mutations associated with PD.

Movement disorders: role of imaging in diagnosis.

PubMed

Mascalchi, Mario; Vella, Alessandra; Ceravolo, Roberto

2012-02-01

Magnetic resonance imaging (MRI and single-photon emission computed tomography (SPECT) have a considerable role in the diagnosis of the single patient with movement disorders. Conventional MRI demonstrates symptomatic causes of parkinsonism but does not show any specific finding in Parkinson's disease (PD). However, SPECT using tracers of the dopamine transporter (DAT) demonstrates an asymmetric decrease of the uptake in the putamen and caudate from the earliest clinical stages. In other degenerative forms of parkinsonism, including progressive supranuclear palsy (PSP), multisystem atrophy (MSA), and corticobasal degeneration (CBD), MRI reveals characteristic patterns of regional atrophy combined with signal changes or microstructural changes in the basal ganglia, pons, middle and superior cerebellar peduncles, and cerebral subcortical white matter. SPECT demonstrates a decreased uptake of tracers of the dopamine D2 receptors in the striata of patients with PSP and MSA, which is not observed in early PD. MRI also significantly contributes to the diagnosis of some inherited hyperkinetic conditions including neurodegeneration with brain iron accumulation and fragile-X tremor/ataxia syndrome by revealing characteristic symmetric signal changes in the basal ganglia and middle cerebellar peduncles, respectively. A combination of the clinical features with MRI and SPECT is recommended for optimization of the diagnostic algorithm in movement disorders. Copyright © 2011 Wiley Periodicals, Inc.

Metadynamics method has been widely used to enhance sampling in molecular simulations. Its original form suffers two major drawbacks, poor convergence in complex (especially biomolecular) systems and its serial nature. The first drawback has been addressed by introduction of a convergent variant known as well-tempered metadynamics. The second was addressed by introduction of a parallel multisystem metadynamics referred to as altruistic metadynamics. Here, we combine both approaches into well-tempered altruistic metadynamics. We provide mathematical arguments and trial simulations to show that it accurately predicts free energy surfaces.

Autoerotic fatalities in the Greater Dusseldorf area correspond to the relevant medicolegal literature. Our results included exclusively young to middle-aged, usually single men who were found dead in their city apartments. Clothing and devices used showed a great variety. Women's or fetish clothing and complex shackling or hanging devices were disproportionately frequent. In most cases, death occurred due to hanging or ligature strangulation. There was no increased incidence of underlying psychiatric disorders. In most of the deceased no or at least no remarkable alcohol intoxication was found. Occasionally, it may be difficult to reliably differentiate autoerotic accidents, accidents occurring in connection with practices of bondage & discipline, dominance & submission (BDSM) from natural death, suicide or homicide.

Epstein-Barr virus-associated hemophagocytic syndrome (EBV-AHS) is often associated with fatal infectious mononucleosis. However, the animal model for EBV-AHS has not been developed. We reported the first animal model for EBV-AHS using rabbits infected with EBV-related herpesvirus of baboon (HVP). Eleven of 13 (85%) rabbits inoculated intravenously with HVP-producing cells developed fatal lymphoproliferative disorders (LPD) between 22 and 105 days after inoculation. LPD was also accompanied by hemophagocytic syndrome (HPS) in nine of these 11 rabbits. The peroral spray of cell-free HVP induced the virus infection with increased anti-EBV-viral capsid antigen-IgG titers in three of five rabbits, and two of these three infected rabbits died of LPD with HPS. Autopsy revealed hepatosplenomegaly and swollen lymph nodes. Atypical lymphoid T cells expressing EBV-encoded small RNA-1 infiltrated diffusely in many organs, frequently involving the lymph nodes, spleen, and liver. Hemophagocytic histiocytosis was observed in the lymph nodes, spleen, bone marrow, and thymus. HVP-DNA was detected in the tissues and peripheral blood from the infected rabbits by polymerase chain reaction or Southern blot analysis. Reverse transcriptase-polymerase chain reaction revealed both HVP-EBNA1 and HVP-EBNA2 transcripts, suggesting latency type III infection. These data indicate that the high rate of rabbit LPD with HPS induction is caused by HVP. This system is useful for studying the pathogenesis, prevention, and treatment of human EBV-AHS.

Hypoglycaemia related to inherited metabolic diseases in adults

PubMed Central

2012-01-01

In non-diabetic adult patients, hypoglycaemia may be related to drugs, critical illness, cortisol or glucagon insufficiency, non-islet cell tumour, insulinoma, or it may be surreptitious. Nevertheless, some hypoglycaemic episodes remain unexplained, and inborn errors of metabolism (IEM) should be considered, particularly in cases of multisystemic involvement. In children, IEM are considered a differential diagnosis in cases of hypoglycaemia. In adulthood, IEM-related hypoglycaemia can persist in a previously diagnosed childhood disease. Hypoglycaemia may sometimes be a presenting sign of the IEM. Short stature, hepatomegaly, hypogonadism, dysmorphia or muscular symptoms are signs suggestive of IEM-related hypoglycaemia. In both adults and children, hypoglycaemia can be clinically classified according to its timing. Postprandial hypoglycaemia can be an indicator of either endogenous hyperinsulinism linked to non-insulinoma pancreatogenic hypoglycaemia syndrome (NIPHS, unknown incidence in adults) or very rarely, inherited fructose intolerance. Glucokinase-activating mutations (one family) are the only genetic disorder responsible for NIPH in adults that has been clearly identified so far. Exercise-induced hyperinsulinism is linked to an activating mutation of the monocarboxylate transporter 1 (one family). Fasting hypoglycaemia may be caused by IEM that were already diagnosed in childhood and persist into adulthood: glycogen storage disease (GSD) type I, III, 0, VI and IX; glucose transporter 2 deficiency; fatty acid oxidation; ketogenesis disorders; and gluconeogenesis disorders. Fasting hypoglycaemia in adulthood can also be a rare presenting sign of an IEM, especially in GSD type III, fatty acid oxidation [medium-chain acyl-CoA dehydrogenase (MCAD), ketogenesis disorders (3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) lyase deficiency, and gluconeogenesis disorders (fructose-1,6-biphosphatase deficiency)].

Substance use disorders in children and adolescents are a significant cause of concern as they can have long term implications in practically every sphere. The etiological factors that contribute to substance use disorders are complex and the formulation must amalgamate and synthesize all the different factors including the predisposing, perpetuating, precipitating and protective factors in order to plan management. Interventions must stem from this comprehensive formulation and must be child-focused, multidisciplinary, multisystemic, with strong family participation and community involvement. The treating team must actively collaborate with the young person and help him/her understand the rationale for treatment in order for them to engage in it. Assessment and treatment of comorbidities are an important part of intervention package. Skill training for problem solving, emotional regulation, social skills, and communication are an essential part of the treatment for substance use disorders in adolescents. Relapse prevention strategies, including how to seek help when there is a lapse must be part and parcel of the interventions delivered to the young person. Substance use disorder interventions must be part of a larger plan that addresses other areas of concern in the young person's life. While there are few studies, and so a relatively weak and preliminary evidence base for pharmacotherapeutic interventions, early evidence shows that their combination with psychosocial interventions may have a synergistic effect on substance use reduction. Substance use disorders affect the entire family and the community at large and thus must be treated holistically, but by individualising the treatment to suit the needs of that particular child and family.

Tuberous sclerosis complex is a multisystem genetic disorder with a range of physical manifestations that require evaluation, surveillance, and management. Individuals with tuberous sclerosis complex also have a range of behavioral, psychiatric, intellectual, academic, neuropsychologic, and psychosocial difficulties. These may represent the greatest burden of the disease. Around 90% of individuals with tuberous sclerosis complex will have some of these difficulties during their lifetime, yet only about 20% ever receive evaluation and treatment. The Neuropsychiatry Panel at the 2012 Tuberous Sclerosis Complex International Consensus Conference expressed concern about the significant "treatment gap" and about confusion regarding terminology relating to the biopsychosocial difficulties associated with tuberous sclerosis complex. The Tuberous Sclerosis Complex Neuropsychiatry Panel coined the term TAND-tuberous sclerosis complex-associated neuropsychiatric disorders-to bring together these multidimensional manifestations of the disorder, and recommended annual screening for TAND. In addition, the Panel agreed to develop a TAND Checklist as a guide for screening. Here, we present an outline of the conceptualization of TAND, rationale for the structure of the TAND Checklist, and include the full US English version of the TAND Checklist. We hope that the unified term TAND and the TAND Checklist will raise awareness of the importance of tuberous sclerosis complex-associated neuropsychiatric disorders and of the major burden of disease associated with it, provide a shared language and a simple tool to describe and evaluate the different levels of TAND, alert clinical teams and families or individuals of the importance of screening, assessment, and treatment of TAND, and provide a shared framework for future studies of tuberous sclerosis complex-associated neuropsychiatric disorders.

Lung Involvement in Systemic Sclerosis

PubMed Central

Hassoun, Paul M.

2011-01-01

Summary Scleroderma is a multisystem disease characterized by a severe inflammatory process and exuberant fibrosis. Lung involvement is a frequent complication and a leading cause of morbidity and mortality in this syndrome. Two major pulmonary syndromes are associated with scleroderma; a pulmonary vascular disorder evolving over time into relatively isolated pulmonary arterial hypertension (PAH), and interstitial lung disease (ILD). Each syndrome, when present, is a cause of morbidity and significantly reduces survival of scleroderma patients when compared to patients free of lung complication. When pulmonary hypertension and ILD are combined, survival is further reduced. Current therapy appears to have no meaningful effect on either condition and, thus, there is a need for better understanding of underlying pathogenic mechanisms. This review focuses on clinical, diagnostic, and therapeutic features of PAH and ILD as well as other frequent but less debilitating lung complications of scleroderma. PMID:21195581

Cystic fibrosis (CF) is the most common, life-shortening, genetic illness affecting children in Australia and New Zealand. The genetic abnormality results in abnormal anion transport across the apical membrane of epithelial cells in a number of organs, including the lungs, gastrointestinal tract, liver and genito-urinary tract. Thus, CF is a multi-system disorder that requires a multi-disciplinary approach. Respiratory disease is the predominant cause of both morbidity and mortality in patients with CF. However, there are significant and clinically relevant gastrointestinal, liver, pancreatic and nutritional manifestations that must be detected and managed in a timely and structured manner. The aim of this review is to provide evidence-based information and clinical algorithms to guide the nutritional and gastrointestinal management of patients with CF. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Wong, Daniel; Ramachandra, Srinivas Sulugodu; Singh, Ashish Kumar

2015-01-01

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

Williams-Beuren Syndrome (WBS) is a multisystem disorder caused by the deletion of contiguous genes on chromosome 7q11.23. Ophthalmologic abnormalities and deficits in visual motor integration are important features of WBS. Here we describe our experience with Brazilian WBS patients and their ophthalmologic features. Sixteen patients with confirmed WBS went through thorough ophthalmologic examination. The most frequent ocular findings in our group of patients were stellate iris pattern (81.2%), hyperopic astigmatism (50%), hyperopia (37.5%), tortuosity of retinal vessel (37.5%) and strabismus (18.7%). This is the second report of ophthalmologic abnormalities in a group of Brazilian individuals with WBS. It is extremely valuable that specific populations are studied so that clinical diagnosis can be refined and management of patients can be driven to the most common presentations of the disease.

Cryopyrin-associated periodic syndromes: diagnosis and management.

PubMed

Miyamae, Takako

2012-04-01

Cryopyrin-associated periodic syndromes (CAPS) are a group of rare autoinflammatory disorders; many cases of CAPS are caused by mutations in the NLRP3 gene. In these conditions, interleukin (IL)-1 is overproduced, and this overproduction plays a major role in disease onset and progression. CAPS include three variants, ranging in order of increasing severity from familial cold autoinflammatory syndrome, previously termed familial cold urticaria, through Muckle-Wells syndrome, to chronic infantile neurologic cutaneous articular syndrome, also known as neonatal onset multisystemic inflammatory disease. Diagnosis of CAPS is initially based on clinical manifestations and medical history, and later confirmed genetically. CAPS should be suspected when characteristic skin lesions, typical periodic fever episodes, bone/joint manifestations, and CNS involvement are recognized. CAPS are life-long diseases, and early diagnosis and early treatment with IL-1-targeted therapies may improve prognosis.

2014-10-01

Polycystic ovary syndrome is now a well-recognized condition affecting 6%-25% of reproductive-aged women, depending on the definition. Over the past 3 decades, research has launched it from relative medical obscurity to a condition increasingly recognized as common in internal medicine practices. It affects multiple systems, and requires a comprehensive perspective on health care for effective treatment. Metabolic derangements and associated complications include insulin resistance and diabetes, hyperlipidemia, hypertension, fatty liver, metabolic syndrome, and sleep apnea. Reproductive complications include oligo-/amenorrhea, sub-fertility, endometrial hyperplasia, and cancer. Associated psychosocial concerns include depression and disordered eating. Additionally, cosmetic issues include hirsutism, androgenic alopecia, and acne. This review organizes this multi-system approach around the mnemonic "MY PCOS" and discusses evaluation and treatment options for the reproductive, cosmetic, and metabolic complications of this condition.

Alcohol abuse can affect more than the heart and the liver. Many observers often do not appreciate the complex and differing aspects of alcohol's effects in pathophysiologies that have been reported in multiple organs. Chronic alcohol abuse is known to be associated with pathophysiological changes that often result in life-threatening clinical outcomes, e.g., breast and colon cancer, pancreatic disease, cirrhosis of the liver, diabetes, osteoporosis, arthritis, kidney disease, immune system dysfunction, hypertension, coronary artery disease, cardiomyopathy, and can be as far-reaching as to cause central nervous system disorders. In this review article, we will discuss the various organs impacted by alcohol abuse. The lack of clear guidelines on the amount and frequency of alcohol intake, complicated by personal demographics, make extrapolations to real-life practices at best difficult for public health policy-makers.

Menkes disease is an X-linked multisystem disorder with epilepsy, kinky hair, and neurodegeneration caused by mutations in the copper transporter ATP7A . Other ATP7A mutations have been linked to juvenile occipital horn syndrome and adult-onset hereditary motor neuropathy. 1,2 About 5%-10% of the patients present with "atypical Menkes disease" characterized by longer survival, cerebellar ataxia, and developmental delay. 2 The intracellular copper transport is regulated by 2 P type ATPase copper transporters ATP7A and ATP7B. These proteins are expressed in the trans-Golgi network that guides copper to intracellular compartments, and in copper excess, it relocates copper to the plasma membrane to pump it out from the cells. 3 ATP7B mutations cause Wilson disease with dystonia, ataxia, tremor, and abnormal copper accumulation in the brain, liver, and other organs. 4 .

22q11.2 Deletion syndrome (22q11.2DS) is the most common microdeletion syndrome in humans, estimated to affect up to 1 in 2,000 live births. Major features of this multisystem condition include congenital anomalies, developmental delay, and an array of early- and later-onset medical and psychiatric disorders. Advances in pediatric care ensure a growing population of adults with 22q11.2DS. Informed by an international panel of multidisciplinary experts and a comprehensive review of the existing literature concerning adults, we present the first set of guidelines focused on managing the neuropsychiatric, endocrine, cardiovascular, reproductive, psychosocial, genetic counseling, and other issues that are the focus of attention in adults with 22q11.2DS. We propose practical strategies for the recognition, evaluation, surveillance, and management of the associated morbidities. PMID:25569435

Epidemiologic studies have reported substance abuse and posttraumatic stress disorder (PTSD) diagnoses as risk factors for suicide among Veterans Health Administration (VHA) patients. Research on risk factors for suicide may not generalize to our understanding of non-fatal intentional self-harm (ISH), given the evidence that these outcomes have unique risk factors. The aims of this study were to examine (1) gender-stratified rates of non-fatal ISH in VHA patients with alcohol abuse/dependence, drug abuse/dependence, and PTSD and (2) gender-stratified interaction between alcohol abuse and dependence and drug abuse and dependence and PTSD in predicting non-fatal ISH. Participants include all VHA care users who received a PTSD diagnosis in Massachusetts from 2000 to 2008 (n=16,004) and an age- and gender-matched comparison group (n=52,502). Data were obtained from the VHA administrative registries. We found evidence of stronger interactions between substance abuse diagnoses and PTSD in predicting non-fatal ISH for females than for males. The interaction contrast (IC) for alcohol abuse and dependence and PTSD in predicting non-fatal ISH among female VHA patients was 62.35/100,000 person-years; for male VHA patients the comparable IC was 21.49/100,000 person-years. For female VHA patients the IC for drug abuse and dependence and PTSD predicting ISH was 256.33/100,000 person-years; no interaction was observed for male VHA patients. This study contributes to the scant literature on gender differences in substance abuse and PTSD among VHA patients. The findings highlight comorbid diagnoses as particularly important risk factors for non-fatal ISH among female VHA patients. Published by Elsevier B.V.

Endocrine manifestations related to inherited metabolic diseases in adults

PubMed Central

2012-01-01

Most inborn errors of metabolism (IEM) are recessive, genetically transmitted diseases and are classified into 3 main groups according to their mechanisms: cellular intoxication, energy deficiency, and defects of complex molecules. They can be associated with endocrine manifestations, which may be complications from a previously diagnosed IEM of childhood onset. More rarely, endocrinopathies can signal an IEM in adulthood, which should be suspected when an endocrine disorder is associated with multisystemic involvement (neurological, muscular, hepatic features, etc.). IEM can affect all glands, but diabetes mellitus, thyroid dysfunction and hypogonadism are the most frequent disorders. A single IEM can present with multiple endocrine dysfunctions, especially those involving energy deficiency (respiratory chain defects), and metal (hemochromatosis) and storage disorders (cystinosis). Non-autoimmune diabetes mellitus, thyroid dysfunction and/or goiter and sometimes hypoparathyroidism should steer the diagnosis towards a respiratory chain defect. Hypogonadotropic hypogonadism is frequent in haemochromatosis (often associated with diabetes), whereas primary hypogonadism is reported in Alström disease and cystinosis (both associated with diabetes, the latter also with thyroid dysfunction) and galactosemia. Hypogonadism is also frequent in X-linked adrenoleukodystrophy (with adrenal failure), congenital disorders of glycosylation, and Fabry and glycogen storage diseases (along with thyroid dysfunction in the first 3 and diabetes in the last). This is a new and growing field and is not yet very well recognized in adulthood despite its consequences on growth, bone metabolism and fertility. For this reason, physicians managing adult patients should be aware of these diagnoses. PMID:22284844

Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem. PMID:22927862

Atypical case of Wolfram syndrome revealed through targeted exome sequencing in a patient with suspected mitochondrial disease

PubMed Central

2012-01-01

Background Mitochondrial diseases comprise a diverse set of clinical disorders that affect multiple organ systems with varying severity and age of onset. Due to their clinical and genetic heterogeneity, these diseases are difficult to diagnose. We have developed a targeted exome sequencing approach to improve our ability to properly diagnose mitochondrial diseases and apply it here to an individual patient. Our method targets mitochondrial DNA (mtDNA) and the exons of 1,600 nuclear genes involved in mitochondrial biology or Mendelian disorders with multi-system phenotypes, thereby allowing for simultaneous evaluation of multiple disease loci. Case Presentation Targeted exome sequencing was performed on a patient initially suspected to have a mitochondrial disorder. The patient presented with diabetes mellitus, diffuse brain atrophy, autonomic neuropathy, optic nerve atrophy, and a severe amnestic syndrome. Further work-up revealed multiple heteroplasmic mtDNA deletions as well as profound thiamine deficiency without a clear nutritional cause. Targeted exome sequencing revealed a homozygous c.1672C > T (p.R558C) missense mutation in exon 8 of WFS1 that has previously been reported in a patient with Wolfram syndrome. Conclusion This case demonstrates how clinical application of next-generation sequencing technology can enhance the diagnosis of patients suspected to have rare genetic disorders. Furthermore, the finding of unexplained thiamine deficiency in a patient with Wolfram syndrome suggests a potential link between WFS1 biology and thiamine metabolism that has implications for the clinical management of Wolfram syndrome patients.

2012-11-30

In the Western world, cases of fatal child neglect due to starvation are extremely rare. When they do occur, particularly at the hands of a parent, such crimes are considered to be caused by mental disorders or personality disorders with severe affective impairment. The present report describes the peculiar case of a couple with a total of four children to care for, who starved a 16-month-old female to death, while all the other children were found to be healthy. After a forensic psychiatric assessment of their criminal responsibility, the couples were both judged guilty and sentenced to 30 years in prison. After a brief overview of the scientific knowledge about filicide, the authors propose a framework that may help to understand and explain the motivations underlying this dreadful crime that shocked the nation, and emphasize the role of the forensic psychiatric investigation into cases of filicide, which may contribute to gain a greater insight into the different motivational factors underlying this phenomenon.

Mitochondria: the next (neurode)generation

PubMed Central

Schon, Eric A.; Przedborski, Serge

2012-01-01

SUMMARY Adult-onset neurodegenerative disorders are disabling and often fatal diseases of the nervous system whose underlying mechanisms of cell death remain, in most instances, unknown. Defects in mitochondrial respiration had previously been proposed to contribute to the occurrence of many, if not all of the most common neurodegenerative disorders. However, the discovery of genes mutated in hereditary forms of these enigmatic diseases has additionally suggested defects in mitochondrial dynamics. Such disturbances can lead to changes in mitochondrial trafficking, in interorganellar communication, and in mitochondrial quality control. These new mechanisms by which mitochondria may also be linked to neurodegeneration will likely have far-reaching implications for our understanding of the pathophysiology and treatment of adult-onset neurodegenerative disorders.

Glycosylphosphatidylinositol (GPI)-anchored proteins are ubiquitously expressed in the human body and are important for various functions at the cell surface. Mutations in many GPI biosynthesis genes have been described to date in patients with multi-system disease and together these constitute a subtype of congenital disorders of glycosylation. We used whole exome sequencing in two families to investigate the genetic basis of disease and used RNA and cellular studies to investigate the functional consequences of sequence variants in the PIGY gene. Two families with different phenotypes had homozygous recessive sequence variants in the GPI biosynthesis gene PIGY. Two sisters with c.137T>C (p.Leu46Pro) PIGY variants had multi-system disease including dysmorphism, seizures, severe developmental delay, cataracts and early death. There were significantly reduced levels of GPI-anchored proteins (CD55 and CD59) on the surface of patient-derived skin fibroblasts (∼20–50% compared with controls). In a second, consanguineous family, two siblings had moderate development delay and microcephaly. A homozygous PIGY promoter variant (c.-540G>A) was detected within a 7.7 Mb region of autozygosity. This variant was predicted to disrupt a SP1 consensus binding site and was shown to be associated with reduced gene expression. Mutations in PIGY can occur in coding and non-coding regions of the gene and cause variable phenotypes. This article contributes to understanding of the range of disease phenotypes and disease genes associated with deficiencies of the GPI-anchor biosynthesis pathway and also serves to highlight the potential importance of analysing variants detected in 5′-UTR regions despite their typically low coverage in exome data.

Background: Trichothiodistrophy (TTD) is a rare autosomal recessive condition that is characterized by a specific congenital hair shaft dysplasia caused by deficiency of sulfur associated with a wide spectrum of multisystem abnormalities. In this article, we study clinical, microscopic, and ultrastructural findings of 20 patients with TTD with the aim to add further insights regarding to this rare condition. Additionally, analyses of our results are compared with those extracted from the literature in order to enhance its comprehensibility. Materials and Methods: Twenty cases of TTD were included: 7 from Mexico and 14 from Spain. Clinical, microscopic, scanning electron microscopy (SEM) studies and X-ray microanalysis (XrMa) were carried out in all of them. Genetic studies were performed in all seven Mexican cases. Patients with xeroderma pigmentosum and xeroderma pigmentosum/TTD-complex were excluded. Results: Cuticular changes and longitudinal crests of the hair shaft were demonstrated. These crests were irregular, disorganized, following the hair longest axis. Hair shaft sulfur deficiency was disposed discontinuously and intermittently rather than uniformly. This severe decrease of sulfur contents was located close to the trichoschisis areas. Only five patients did not show related disturbances. Micro-dolichocephaly was observed in five cases and represented the most frequent facial dysmorphism found. It is also remarkable that all patients with urologic malformations also combined diverse neurologic disorders. Moreover, three Mexican sisters demonstrated the coexistence of scarce pubic vellus hair, developmental delay, onychodystrophy, and maxillar/mandibullar hypoplasia. Conclusions: TTD phenotype has greatly varied from very subtle forms to severe alterations such as neurologic abnormalities, blindness, lamellar ichthyosis and gonadal malformations. Herein, a multisystem study should be performed mandatorily in patients diagnosed with TTD. PMID:23180925

The multisystem degeneration amyotrophic lateral sclerosis - neuropathological staging and clinical translation.

PubMed

Verde, Federico; Del Tredici, Kelly; Braak, Heiko; Ludolph, Albert

2017-12-01

Amyotrophic lateral sclerosis (ALS) is traditionally considered a disease affecting exclusively motor neurons. However, much evidence points towards additional involvement of brain systems other than the motor. As much as half of ALS patients display cognitive-behavioral disturbances. ALS shares with a considerable proportion of FTD cases the same neuropathological substrate, namely, inclusions of abnormally phosphorylated protein TDP-43 (pTDP-43). In analogy with pathological staging systems elaborated in the past decades for Alzheimer's disease (AD) and Parkinson's disease (PD), a model of staging of pTDP-43 pathology in sporadic ALS (sALS) has been recently proposed. According to it, 4 stages can be recognized, where pTDP-43 inclusions are found in the agranular motor cortex and α-motor neurons of the brain stem and spinal cord (stage 1), in prefrontal neocortex (middle frontal gyrus), reticular formation, and precerebellar nuclei (stage 2), in further areas of the prefrontal neocortex (gyrus rectus and orbitofrontal gyri), postcentrally located sensory cortex, and basal ganglia (stage 3), and in the anteromedial temporal lobe including the hippocampus (stage 4). Based on this staging effort, a corticofugal axonal model for spreading of pathology can be hypothesized, whereby pathology starts in the primary motor cortex and spreads from there via axonal projections to lower motor neurons and to subcortical structures. Recent neuroradiological evidence seems to support the proposed staging system. From the clinical standpoint, a proportion of ALS patients display extramotor deficits (namely cognitive-behavioural disturbances, impaired ocular movements, and extrapyramidal alterations), which seem to correspond to the pathological involvement of the relevant cerebral structures. This review describes neuropathological sALS staging and addresses clinical evidence corresponding to this staging, pointing towards the concept of ALS as a multisystem brain degeneration disorder instead of a disease confined to motor neurons.

Ataxia telangiectasia (AT) is a progressive multisystem autosomal recessive disorder caused by mutations in the AT-mutated (ATM) gene. Early onset AT in children is characterized by cerebellar degeneration, leading to motor impairment. Lung disease and cancer are the two most common causes of death in AT patients. Accelerated thymic involution may contribute to the cancer, and recurrent and/or chronic respiratory infections may be a contributing factor to lung disease in AT. AT patients have fertility issues, are highly sensitive to ionizing radiation and they present oculocutaneous telangiectasia. Current treatments only slightly ameliorate disease symptoms; therapy that alters or reverses the course of the disease has not yet been discovered. Previously, we have shown that ATM -/- pigs, a novel model of AT, present with a loss of Purkinje cells, altered cerebellar cytoarchitecture and motor coordination deficits. ATM -/- porcine model not only recapitulates the neurological phenotype, but also other multifaceted clinical features of the human disease. Our current study shows that ATM -/- female pigs are infertile, with anatomical and functional signs of an immature reproductive system. Both male and female ATM -/- pigs show abnormal thymus structure with decreased cell cycle and apoptosis markers in the gland. Moreover, ATM -/- pigs have an altered immune system with decreased CD8 + and increased natural killer and CD4 + CD8 + double-positive cells. Nevertheless, ATM -/- pigs manifest a deficient IgG response after a viral infection. Based on the neurological and peripheral phenotypes, the ATM -/- pig is a novel genetic model that may be used for therapeutic assessments and to identify pathomechanisms of this disease.

Polled and Multisystemic Syndrome (PMS) is a novel developmental disorder occurring in the progeny of a single bull. Its clinical spectrum includes polledness (complete agenesis of horns), facial dysmorphism, growth delay, chronic diarrhea, premature ovarian failure, and variable neurological and cardiac anomalies. PMS is also characterized by a deviation of the sex-ratio, suggesting male lethality during pregnancy. Using Mendelian error mapping and whole-genome sequencing, we identified a 3.7 Mb deletion on the paternal bovine chromosome 2 encompassing ARHGAP15, GTDC1 and ZEB2 genes. We then produced control and affected 90-day old fetuses to characterize this syndrome by histological and expression analyses. Compared to wild type individuals, affected animals showed a decreased expression of the three deleted genes. Based on a comparison with human Mowat-Wilson syndrome, we suggest that deletion of ZEB2, is responsible for most of the effects of the mutation. Finally sperm-FISH, embryo genotyping and analysis of reproduction records confirmed somatic mosaicism in the founder bull and male-specific lethality during the first third of gestation. In conclusion, we identified a novel locus involved in bovid horn ontogenesis and suggest that epithelial-to-mesenchymal transition plays a critical role in horn bud differentiation. We also provide new insights into the pathogenicity of ZEB2 loss of heterozygosity in bovine and humans and describe the first case of male-specific lethality associated with an autosomal locus in a non-murine mammalian species. This result sets PMS as a unique model to study sex-specific gene expression/regulation. PMID:23152852

A model for localized 300 kV X-irradiation of the rat stomach was developed. After irradiation with single doses, three distinct gastric disorders were observed which occurred at different latency times. Acute death 2-3 weeks after irradiation was caused by an erosive and ulcerative gastritis and occurred in all animals given 28.5 Gy without diet, in 17% of the animals given 28.5 Gy plus diet, and in 13% of the animals given 23 Gy. Subacute to chronic fatal disorders 4 weeks to 7 months after irradiation were seen as stomach dilatation and gastroparesis, associated with the replacement of the normal gastricmore » mucosa by a hyperkeratinized multilayered squamous epithelium. These disorders occurred in 40-100% of the animals after doses between 16 Gy and 28.5 Gy (+diet). An ED 50 value of 19.2 Gy (16.5-21.2 Gy, 95% confidence interval) was calculated for this gastroparesis. Late gastric obstruction exceeding 7 months after irradiation was seen in the rats because of profound changes in the gastric wall in 13-18% of the animals after doses between 23 Gy and 14 Gy. In animals surviving these three periods, an atrophic mucosa and intestinal metaplasia developed. From functional and morphohistological studies, it can be concluded that there are differences in the pathogenesis of the fatal radiation damage for each of these periods after irradiation.« less

Lyme borreliosis is a multisystem disorder with a diverse spectrum of clinical manifestations, caused by spirochaetes of the Borrelia burgdorferi sensu lato complex. It is an infectious disease that can be successfully cured by antibiotic therapy in the early stages; however, the possibility of the appearance of persistent signs and symptoms of disease following antibiotic treatment is recognized. It is known that Lyme borreliosis mimics multiple diseases that were never proven to have a spirochaete aetiology. Using complete modified Kelly-Pettenkofer medium we succeeded in cultivating live B. burgdorferi sensu lato spirochaetes from samples taken from people who suffered from undefined disorders, had symptoms not typical for Lyme borreliosis, but who had undergone antibiotic treatment due to a suspicion of having Lyme disease even though they were seronegative. We report the first recovery of live B. burgdorferi sensu stricto from residents of southeastern USA and the first successful cultivation of live Borrelia bissettii-like strain from residents of North America. Our results support the fact that B. bissettii is responsible for human Lyme borreliosis worldwide along with B. burgdorferi s.s. The involvement of new spirochaete species in Lyme borreliosis changes the understanding and recognition of clinical manifestations of this disease.

Plasma lipids, namely cholesterol and triglyceride, and lipoproteins, such as low-density lipoprotein (LDL) and high-density lipoprotein, serve numerous physiological roles. Perturbed levels of these traits underlie monogenic dyslipidemias, a diverse group of multisystem disorders. We are on the verge of having a relatively complete picture of the human dyslipidemias and their components. Recent advances in genetics of plasma lipids and lipoproteins include the following: (1) expanding the range of genes causing monogenic dyslipidemias, particularly elevated LDL cholesterol; (2) appreciating the role of polygenic effects in such traits as familial hypercholesterolemia and combined hyperlipidemia; (3) accumulating a list of common variants that determine plasma lipids and lipoproteins; (4) applying exome sequencing to identify collections of rare variants determining plasma lipids and lipoproteins that via Mendelian randomization have also implicated gene products such as NPC1L1 , APOC3 , LDLR , APOA5 , and ANGPTL4 as causal for atherosclerotic cardiovascular disease; and (5) using naturally occurring genetic variation to identify new drug targets, including inhibitors of apolipoprotein (apo) C-III, apo(a), ANGPTL3, and ANGPTL4. Here, we compile this disparate range of data linking human genetic variation to plasma lipids and lipoproteins, providing a "one stop shop" for the interested reader.

Type IV Collagens and Basement Membrane Diseases: Cell Biology and Pathogenic Mechanisms.

2015-01-01

Basement membranes are highly specialized extracellular matrices. Once considered inert scaffolds, basement membranes are now viewed as dynamic and versatile environments that modulate cellular behaviors to regulate tissue development, function, and repair. Increasing evidence suggests that, in addition to providing structural support to neighboring cells, basement membranes serve as reservoirs of growth factors that direct and fine-tune cellular functions. Type IV collagens are a major component of all basement membranes. They evolved along with the earliest multicellular organisms and have been integrated into diverse fundamental biological processes as time and evolution shaped the animal kingdom. The roles of basement membranes in humans are as complex and diverse as their distributions and molecular composition. As a result, basement membrane defects result in multisystem disorders with ambiguous and overlapping boundaries that likely reflect the simultaneous interplay and integration of multiple cellular pathways and processes. Consequently, there will be no single treatment for basement membrane disorders, and therapies are likely to be as varied as the phenotypes. Understanding tissue-specific pathology and the underlying molecular mechanism is the present challenge; personalized medicine will rely upon understanding how a given mutation impacts diverse cellular functions.

Neurofibromatosis (NF) is a multisystem disorder and tumor predisposition syndrome caused by genetic mutation on chromosome 17-17q11.2 in NF type 1 (NF1), and on chromosome 22-22q12.2 in NF type 2. The disorder is characterized by considerable heterogeneity of clinical expression. NF1 is the form with the most characteristic ocular manifestations. Lisch nodules of the iris are among the well-known diagnostic criteria for the disease. Glaucoma and associated globe enlargement have been described in a significant proportion of patients with NF1 and orbital–facial involvement. Optic nerve glioma may cause strabismus and proptosis, and palpebral neurofibroma may reach considerable size and occasionally show malignant transformation. Near infrared reflectance has greatly contributed to enhancing our knowledge on choroidal alterations in NF1. Indeed, some authors have proposed to include these among the diagnostic criteria. Optical coherence tomography has given new insight on retinal alterations and is a noninvasive tool in the management of optic nerve gliomas in children. Ocular manifestations in NF type 2 can range from early-onset cataracts in up to 80% of cases to optic nerve hamartomas and combined pigment epithelial and retinal hamartomas. PMID:27257370

Cockayne syndrome pathogenesis: lessons from mouse models.

2013-01-01

Cockayne syndrome (CS) is a rare multisystem disorder characterized by cachectic dwarfism, nervous system abnormalities and features of premature aging. CS symptoms are associated with mutations in 5 genes, CSA, CSB, XPB, XPD and XPG encoding for proteins involved in the transcription-coupled subpathway of nucleotide excision DNA repair (NER). Mutant mice have been generated for all CS-associated genes and provide tools to examine how the cellular defects translate into CS symptoms. Mice deficient for Csa or Csb genetically mimic CS in man, and develop mild CS symptoms including reduced fat tissue, photoreceptor cell loss, and mild, but characteristic, nervous system pathology. These mild CS models are converted into severe CS models with short life span, progressive nervous system degeneration and cachectic dwarfism after simultaneous complete inactivation of global genome NER. A spectrum of mild-to-severe CS-like symptoms occurs in Xpb, Xpd, and Xpg mice that genetically mimic patients with a disorder that combines CS symptoms with another NER syndrome, xeroderma pigmentosum. In conclusion, CS mouse models mice develop a range of CS phenotypes and open promising perspectives for testing interventional approaches. Copyright © 2013 Elsevier Ireland Ltd.

Preeclampsia is a multi-system disorder involved in pregnancy without an effective treatment except delivery. The precise pathogenesis of this complicated disorder is still not completely understood. The objective of this study is to evaluate the alterations of protein expression and phosphorylations that are important in regulating placental cell function in preterm and term preeclampsia. Using the Protein Pathway Array, 38 proteins in placental tissues were found to be differentially expressed between preterm preeclampsia and gestational age matched control, while 25 proteins were found to be expressed differentially between term preeclampsia and matched controls. Among these proteins, 16 proteins and their associated signaling pathways overlapped between preterm and term preeclampsia, suggesting the common pathogenesis of two subsets of disease. On the other hand, many proteins are uniquely altered in either preterm or term preeclampsia and correlated with severity of clinical symptoms and outcomes, therefore, providing molecular basis for these two subsets of preeclampsia. Furthermore, the expression levels of some of these proteins correlated with neonatal small for gestational age (PAI-1 and PAPP-A) and adverse outcomes (Flt-1) in women with preterm preeclampsia. These proteins could potentially be used as candidate biomarkers for predicting outcomes of preeclampsia.

Andersen-Tawil syndrome (ATS) is an autosomal dominant, multisystem channelopathy characterized by periodic paralysis, ventricular arrhythmias and distinctive dysmorphic facial or skeletal features. The disorder displays marked intrafamilial variability and incomplete penetrance. Myasthenia gravis (MG) is an autoimmune disorder that demonstrates progressive fatigability, in which the nicotinic acetylcholine receptor (AChR) at neuromuscular junctions is the primary autoantigen. The present study reports a rare case of a 31-year-old woman with a history of morbid obesity and periodic weakness, who presented with hemodynamic instability, cardiogenic shock and facial anomalies. Laboratory results revealed hypokalemia and an elevated anti-AChR antibody expression levels. Electrocardiography demonstrated prolonged QT-interval, ST-elevation, and subsequent third-degree atrioventricular block. Neurological examination revealed bilateral ptosis, horizontal diplopia, dysarthria and generalized weakness. No mutations in the potassium channel inwardly rectifying subfamily J member 2 gene were detected in the present case. The patient was treated with oral potassium supplementation and an acetylcholinesterase inhibitor (pyridostigmine), after which the symptoms were improved. To the best of our knowledge, the present case report was the first to describe concomitant presentation of both ATS and MG, which represents a diagnostic and therapeutic challenge.

Recent findings suggest an important role for inflammation in the neurobiology of bipolar disorder (BD). Interleukin 33 (IL-33) is a cytokine with multiple functions and may act as a nuclear factor regulating transcription and as an "alarmin". IL-33 exerts part of its function through the receptor ST2 that also exists in a soluble form (sST2). This study was performed to evaluate IL-33 and sST2 plasma levels in BD patients. We evaluated IL33 and sST2 plasma levels of 46 BD patients (23 in euthymia and 23 in mania) and 23 healthy controls using enzyme-linked immunosorbent assay (ELISA). BD patients were age and gender matched healthy controls. IL-33 levels were higher in BD patients (p=0.02) but there was no difference in sST2 (p=0.55). IL33 and sST2 plasma levels were not correlated with age, neither was influenced by clinical comorbidities nor medications in use. These findings corroborate the view of BD as a multisystem condition with a proinflammatory profile. Copyright © 2014 Elsevier B.V. All rights reserved.

Extensive intramuscular manifestation of sarcoidosis with initially missed diagnosis and delayed therapy: a case report.

Sarcoidosis is a multisystemic granulomatous disorder, which in nearly all cases involves the lungs and other organs. Isolated forms of sarcoidosis within the muscles, but without lung involvement, are extremely rare and can lead to delayed or even false diagnosis. A 52-year-old white, Swiss man presented with painful arm cramps and a history of symptoms over the previous 3 years. In the initial clinical investigation, our patient also showed edema in both legs without any other complaints. After performing an magnetic resonance imaging scan of his extremities and a positron emission tomography/computed tomography scan, diffuse myositis was described. The subsequent muscle biopsy provided the surprising diagnosis of muscle sarcoidosis, without involvement of the lungs or any other organ. After starting therapy with glucocorticoids, his symptoms improved immediately. Sarcoidosis is a common disorder, which in most cases affects the lungs. In this case report an isolated sarcoidosis is described without lung involvement, but with involvement of the muscles of the extremities and the trunk. Reported cases of sarcoidosis only involving skeletal muscle and without lung involvement are extremely rare. Radiologists should consider this presentation of sarcoidosis to avoid delayed diagnosis and therapy.

Pseudoxanthoma Elasticum is a Metabolic Disease

2011-01-01

Pseudoxanthoma elasticum (PXE) is a pleiotropic multisystem disorder affecting skin, eyes, and the cardiovascular system with progressive pathological mineralization. It is caused by mutations in the ABCC6 gene expressed primarily in the liver and kidneys, and at very low levels, if at all, in tissues affected by PXE. A question has arisen regarding the pathomechanism of PXE, particularly the “metabolic” versus the “PXE cell” hypotheses. We examined a murine PXE model (Abcc6−/−) by transplanting muzzle skin from knock-out (KO) and wild-type (WT) mice onto the back of WT and KO mice using mineralization of the connective tissue capsule surrounding the vibrissae as an early phenotypic biomarker. Grafting of WT mouse muzzle skin onto the back of KO mice resulted in mineralization of vibrissae, while grafting KO mouse muzzle skin onto the WT mice did not. Thus, these findings implicate circulatory factors as a critical component of the mineralization process. This mouse grafting model supports the notion that PXE is a systemic metabolic disorder with secondary mineralization of connective tissues and that the mineralization process can be countered or even reversed by changes in the homeostatic milieu.

Treatment of severe acute pancreatitis and its complications

2014-01-01

Severe acute pancreatitis (SAP), which is the most serious type of this disorder, is associated with high morbidity and mortality. SAP runs a biphasic course. During the first 1-2 wk, a pro-inflammatory response results in systemic inflammatory response syndrome (SIRS). If the SIRS is severe, it can lead to early multisystem organ failure (MOF). After the first 1-2 wk, a transition from a pro-inflammatory response to an anti-inflammatory response occurs; during this transition, the patient is at risk for intestinal flora translocation and the development of secondary infection of the necrotic tissue, which can result in sepsis and late MOF. Many recommendations have been made regarding SAP management and its complications. However, despite the reduction in overall mortality in the last decade, SAP is still associated with high mortality. In the majority of cases, sterile necrosis should be managed conservatively, whereas in infected necrotizing pancreatitis, the infected non-vital solid tissue should be removed to control the sepsis. Intervention should be delayed for as long as possible to allow better demarcation and liquefaction of the necrosis. Currently, the step-up approach (delay, drain, and debride) may be considered as the reference standard intervention for this disorder. PMID:25320523

Youth with Neuromuscular Disorders (NMD) who are wheelchair users can now survive well into adulthood if their multisystem comorbidities are prudently managed. Uptake of health behaviors may optimize their health outcomes. To explore youths' perceptions of health, health behaviors and healthcare engagement. This qualitative study purposefully recruited 11 youth with NMD from a concurrent, population-based study for variability of age, gender, type of NMD and their ratings of motivation and engagement. Interview data were analyzed and synthesized by thematic content. Participants perceived healthcare engagement as being given tools (knowledge and responsibility) and using them to maintain their finely balanced health. Nested in adequate social, emotional and physical support, they took responsibility for creatively integrating health behaviors they felt were informed by credible knowledge, gained primarily through personal experience. Cognizant of their compromised health, youth with NMD in this study were motivated to maintain their physical health. Limited NMD condition specific knowledge challenged youths' uptake of health behaviors. They valued a learning partnership with their healthcare professionals. By embracing the youth's experience based knowledge and through facilitating supportive relationships, healthcare professionals co-construct youth's healthcare engagement that may optimize health behaviors and outcomes.

Polymerase γ gene POLG determines the risk of sodium valproate-induced liver toxicity.

Sodium valproate (VPA) is widely used throughout the world to treat epilepsy, migraine, chronic headache, bipolar disorder, and as adjuvant chemotherapy. VPA toxicity is an uncommon but potentially fatal cause of idiosyncratic liver injury. Rare mutations in POLG, which codes for the mitochondrial DNA polymerase γ (polγ), cause Alpers-Huttenlocher syndrome (AHS). AHS is a neurometabolic disorder associated with an increased risk of developing fatal VPA hepatotoxicity. We therefore set out to determine whether common genetic variants in POLG explain why some otherwise healthy individuals develop VPA hepatotoxicity. We carried out a prospective study of subjects enrolled in the Drug Induced Liver Injury Network (DILIN) from 2004 to 2008 through five US centers. POLG was sequenced and the functional consequences of VPA and novel POLG variants were evaluated in primary human cell lines and the yeast model system Saccharomyces cerevisiae. Heterozygous genetic variation in POLG was strongly associated with VPA-induced liver toxicity (odds ratio = 23.6, 95% confidence interval [CI] = 8.4-65.8, P = 5.1 × 10⁻⁷). This was principally due to the p.Q1236H substitution which compromised polγ function in yeast. Therapeutic doses of VPA inhibited human cellular proliferation and high doses caused nonapoptotic cell death, which was not mediated through mitochondrial DNA depletion, mutation, or a defect of fatty acid metabolism. These findings implicate impaired liver regeneration in VPA toxicity and show that prospective genetic testing of POLG will identify individuals at high risk of this potentially fatal consequence of treatment.

Although many inflammatory cytokines are prognostic in sepsis, the utility of cytokines in evaluating disease severity in pediatric hematology/oncology patients with septic shock was rarely studied. On the other hand, a single particular cytokine is far from ideal in guiding therapeutic intervention, but combination of multiple biomarkers improves the accuracy. In this prospective observational study, 111 episodes of septic shock in pediatric hematology/oncology patients were enrolled from 2006 through 2012. Blood samples were taken for inflammatory cytokine measurement by cytometric bead array (CBA) technology at the initial onset of septic shock. Interleukin (IL)-6 and IL-10 were significantly elevated in majority of patients, while tumor necrosis factor (TNF)-α and interferon (IFN)-γ were markedly increased in patients with high pediatric index of mortality 2 (PIM2) score and non-survivors. All the four cytokines paralleled the PIM2 score and differentially correlated with hemodynamic disorder and fatal outcomes. The pediatric multiplex cytokine score (PMCS), which integrated the four cytokines into one score system, was related to hemodynamic disorder and mortality as well, but showed more powerful prediction ability than each of the four cytokines. PMCS was an independent predictive factor for fatal outcome, presenting similar discriminative power with PIM2, with accuracy of 0.83 (95% CI, 0.71-0.94). In conclusion, this study develops a cytokine scoring system based on CBA technique, which performs well in disease severity and fatality prediction in pediatric hematology/oncology patients with septic shock.

Many nurse researchers have designed strategies to assist health care practitioners to move evidence into practice. While many have been identified as "models," most do not have a conceptual framework. They are unidirectional, complex, and difficult for novice research users to understand. These models have focused on empirical knowledge and ignored the importance of practitioners' tacit knowledge. The Communities of Practice conceptual framework allows for the integration of tacit and explicit knowledge into practice. This article describes the development of a new translation model, the Multisystem Model of Knowledge Integration and Translation, supported by the Communities of Practice conceptual framework.

Chemical burns and pulmonary complications are the most common problems encountered in the patient immersed in gasoline. Our patient demonstrated a 46-percent total-body-surface area, partial-thickness chemical burn. Although he did not develop bronchitis or pneumonitis, he did display persistent atelectasis, laryngeal edema, and subsequent upper airway obstruction. This had not previously been reported in gasoline inhalation injuries. Hydrocarbon hepatitis secondary to the vascular endothelial damage is apparently a reversible lesion with no reported long-term sequelae. Gasoline immersion injuries may be a series multisystem injury and require the burn surgeon to take a multisystem approach to its diagnosis and treatment.

Sinusoidal obstructive syndrome (SOS) is a potentially fatal form of hepatic injury after hematopoietic stem cell transplantation. Patients can develop liver dysfunction, portal hypertension, ascites, coagulopathies, and multisystem organ failure. The mortality rate of severe SOS has been reported as high as 98% by day 100 after transplantation. Defibrotide, which is now approved for the treatment of SOS, has significantly decreased mortality. Defibrotide is a polynucleotide with profibrinolytic, anti-ischemic, and anti-inflammatory activity. These properties can increase the risk of life-threatening bleeding in this patient population. Previous protocols have suggested maintaining international normalized ratio ≤ 1.5, platelets > 30 k/uL, and fibrinogen ≥ 150 mg/dL to minimize this risk of bleeding. However, this can be challenging in fluid-sensitive patients with SOS. Thromboelastography (TEG) is a functional assay that evaluates the balance of procoagulant and anticoagulant proteins. In this series, TEG was used to guide defibrotide therapy as well as blood product transfusions in SOS patients with abnormal coagulation studies. Each patient recovered from SOS and had no bleeding complications. A randomized clinical trial is the next step in supporting the use of TEG in SOS patients with abnormal coagulation studies receiving defibrotide therapy.

2015-09-01

Tuberous sclerosis complex is a genetic disorder with multisystem involvement that poses significant challenges to the affected child and family. Caregiver knowledge in the South African population has not previously been reported. A prospective study of the parents of 21 children with tuberous sclerosis complex was undertaken. Median parental age was 38 (interquartile range 34.5-45) years. Parents were randomly allocated to receive written information about the condition, or to receive verbal counseling already established in clinic. A significant difference (P = .001) was observed in the change in the mean knowledge scores for the parent group that received written information (34.2 at baseline, 51.7 at the second visit. This impact was higher in parents with an education level of at least grade 8 (P = .003). Parental understanding of tuberous sclerosis complex can be improved by provision of written information and should be routinely available in a readily understandable format. © The Author(s) 2014.

Medulloblastoma in a toddler with Gorlin syndrome.

2018-04-01

Gorlin syndrome (GS) is a rare hereditary multisystem disorder caused by mutations in PTCH1, PTCH2 , or SUFU . It is characterized by multiple anomalies and an increased risk of developing various tumors. Basal cell carcinoma is most common, and medulloblastoma (MB) is especially frequent in patients with SUFU mutations. MB treatment often includes radiation therapy in patients older than 3 years; however, such treatment is very toxic to patients with GS. Most reported cases of MB in patients with GS present after GS is diagnosed. We report a male toddler with multicentric posterior fossa tumor and calcifications along the falx cerebri, suggesting MB and GS. Pathology revealed nodular MB. His testing confirmed a germline SUFU mutation. His tumor resolved with three induction cycles of chemotherapy, but he died of respiratory failure due to infection at 20 months of age. Overlooking calcifications along the falx cerebri in children with MB can induce significant morbidity.

Celiac disease and non-celiac gluten sensitivity

PubMed Central

Lebwohl, Benjamin; Ludvigsson, Jonas F

2015-01-01

Celiac disease is a multisystem immune based disorder that is triggered by the ingestion of gluten in genetically susceptible individuals. The prevalence of celiac disease has risen in recent decades and is currently about 1% in most Western populations. The reason for this rise is unknown, although environmental factors related to the hygiene hypothesis are suspected. The pathophysiology of celiac disease involves both the innate and adaptive immune response to dietary gluten. Clinical features are diverse and include gastrointestinal symptoms, metabolic bone disease, infertility, and many other manifestations. Although a gluten-free diet is effective in most patients, this diet can be burdensome and can limit quality of life; consequently, non-dietary therapies are at various stages of development. This review also covers non-celiac gluten sensitivity. The pathophysiology of this clinical phenotype is poorly understood, but it is a cause of increasing interest in gluten-free diets in the general population. PMID:26438584

Morgellons disease (MD) is an emerging multisystem illness characterized by skin lesions with unusual filaments embedded in or projecting from epithelial tissue. Filament formation results from abnormal keratin and collagen expression by epithelial-based keratinocytes and fibroblasts. Recent research comparing MD to bovine digital dermatitis, an animal infectious disease with similar skin features, provided clues that spirochetal infection could play an important role in the human disease as it does in the animal illness. Based on histological staining, immunofluorescent staining, electron microscopic imaging and polymerase chain reaction, we report the detection of Borrelia spirochetes in dermatological tissue of  four randomly-selected MD patients. The association of MD with spirochetal infection provides evidence that this infection may be a significant factor in the illness and refutes claims that MD lesions are self-inflicted and that people suffering from this disorder are delusional. Molecular characterization of the Borrelia spirochetes found in MD patients is warranted.

PubMed

Hilhorst-Hofstee, Yvonne

2013-01-01

Marfan syndrome is a multi-system disorder of dominant inheritance in which the cardiovasculature, in particular the aorta, the eyes and the skeleton are affected. Diagnostic assessment and treatment of patients who are suspected of or have Marfan syndrome should preferably be done by multidisciplinary teams such as those found in specialised Marfan syndrome centres. The practice guideline is intended for all care givers involved with the recognition, diagnosis, consultations and the medicinal and surgical treatment of Marfan patients; it includes referral criteria and information on the referral process. A diagnosis of Marfan syndrome is based on international criteria in which aortic root dilatation and dissection, ectopia lentis, an affected first-degree family member and a pathogenic FBN1 mutation are the cardinal features. Alternative diagnoses are also included in the practice guideline. Recommendations are given for the monitoring and treatment of Marfan patients during pregnancy and delivery. Advice on lifestyle is mainly focussed on sports activities.

Amniotic Band Syndrome: A Review of 2 Cases.

2018-04-03

Amniotic band syndrome is a rare congenital disorder caused by entrapment of fetal parts (usually a limb or digits) in fibrous amniotic bands while in utero that presents with complex multisystem anomalies. The authors report 2 children with amniotic band syndrome who presented to the ophthalmic unit of the authors' pediatric hospital. One of them presented with telecanthus, syndactyly, amputated toes, and unilateral epiphora diagnosed as congenital nasolacrimal duct obstruction. She was managed conservatively with lacrimal sac massage and provided with refractive correction while she simultaneously underwent multiple surgeries for correction of clubfoot and craniosynostosis. The second patient presented with cleft lip, cleft palate, multiple constriction bands in upper limbs and fingers with unilateral microphthalmos, microcornea, typical iris coloboma, and retinochoroidal coloboma, very similar to a case reported in literature. These 2 cases provide an overview of the clinical spectrum of ophthalmic manifestations along with their staged optimum rehabilitation.

Cryopyrin-associated periodic syndrome: an update on diagnosis and treatment response.

PubMed

Yu, Justin R; Leslie, Kieron S

2011-02-01

Cryopyrin-associated periodic syndrome (CAPS) is a rare hereditary inflammatory disorder encompassing a continuum of three phenotypes: familial cold autoinflammatory syndrome, Muckle-Wells syndrome, and neonatal-onset multisystem inflammatory disease. Distinguishing features include cutaneous, neurological, ophthalmologic, and rheumatologic manifestations. CAPS results from a gain-of-function mutation of the NLRP3 gene coding for cryopyrin, which forms intracellular protein complexes known as inflammasomes. Defects of the inflammasomes lead to overproduction of interleukin-1, resulting in inflammatory symptoms seen in CAPS. Diagnosis is often delayed and requires a thorough review of clinical symptoms. Remarkable advances in our understanding of the genetics and the molecular pathway that is responsible for the clinical phenotype of CAPS has led to the development of effective treatments. It also has become clear that the NLRP3 inflammasome plays a critical role in innate immune defense and therefore has wider implications for other inflammatory disease states.

Interstitial granulomatous dermatitis with arthritis is an uncommon systemic disorder involving the cutaneous and musculoskeletal systems. The eruption may mimic other dermatoses including granuloma annulare, erythema chronicum migrans, and the inflammatory stage of morphea. Key histopathologic characteristics, along with clinical correlation, allow accurate diagnosis. We describe the clinical, serologic, and histologic features in three patients with interstitial granulomatous dermatitis with arthritis. Skin biopsy specimens were examined and correlated with the clinical and laboratory findings. Erythematous, annular, indurated plaques on the extremities were present in two women. An erythematous, papular eruption on the head and neck was present in a third patient. All patients had myalgia and migratory polyarthralgias of the extremities along with various serologic abnormalities. Histologic examination revealed a dense lymphohistiocytic interstitial infiltrate involving primarily the reticular dermis. Foci of necrobiotic collagen were present. Vasculitis was absent. Interstitial granulomatous dermatitis with arthritis is unique multisystem disease with variable cutaneous expression. Abnormal serologic findings indicate a possible connection to collagen vascular disease.

[The allergic child at school. What do we need to know?].

2016-01-01

Allergy is a multisystem disease in children that often occurs with the coexistence of diverse clinical manifestations that cause great impact on quality of life and academic performance due to sleep disorders arising from the disease or treatment, and absenteeism that children may experience. Because of the time spent in school, there is a possibility that allergic reactions may occur first in these facilities, where a lack of staff knowledge has been found regarding how to proceed in allergy crisis situations. Cooperative action among health teams, community, parents, and school authorities is essential to ensure that the school can prevent, recognize, and ensure quick access to emergency services (if needed) and treatment protocols for allergic reactions, thus allowing allergic children to be better protected in the school environment, which should be considered an extension of the home environment and an important arm in proper management to control the disease.

Churg-Strauss syndrome (CSS) also called allergic granulomatosis and angiitis is a multisystem disorder. Churg-Strauss syndrome is defined as an eosinophil-rich, granulomatous inflammation involving the respiratory tract, along with necrotizing vasculitis affecting small- to medium-sized vessels, and is associated with asthma and eosinophilia. Renal involvement in CSS varies from 26 to 88 % but is usually of mild to moderate stage, and advanced renal failure is uncommon. We encountered an unusual case of 27-year-old man with asthma and primary focal segmental glomerulosclerosis diagnosed as CSS showing myeloperoxidase anti-neutrophil cytoplasmic antibody-associated acute kidney injury with crescentic glomerulonephritis. Patient responded to steroid and cyclophosphamide. Over a follow-up of 2 months, he has no hematuria/eosinophilia and serum creatinine of 2.3 mg/dL has decreased to 1.7 mg/dL.

Evaluation of the norrie disease gene in a family with incontinentia pigmenti.

PubMed

Shastry, B S; Trese, M T

2000-01-01

Incontinentia pigmenti (IP) is an ectodermal multisystem disorder which can affect dental, ocular, cardiac and neurologic structures. The ocular changes of IP can have a very similar appearance to the retinal detachment of X-linked familial exudative vitreoretinopathy, which has been shown to be caused by the mutations in the Norrie disease gene. Therefore, it is of interest to determine whether similar mutations in the gene can account for the retinal pathology in patients with IP. To test our hypothesis, we have analyzed the entire Norrie disease gene for a family with IP, by single strand conformational polymorphism followed by DNA sequencing. The sequencing data revealed no disease-specific sequence alterations. These data suggest that ocular findings of IP are perhaps associated with different genes and there is no direct relationship between the genotype and phenotype. Copyright 2000 S. Karger AG, Basel

Monogenic Lupus.

Lo, Mindy S

2016-12-01

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease known for its clinical heterogeneity. Over time, new insights into the complex genetic origin of SLE have started to explain some of this clinical variability. These findings, reviewed here, have also yielded important understanding in the immune mechanisms behind SLE pathogenesis. Several new monogenic disorders with lupus-like phenotype have been described. These can be organized into physiologic pathways that parallel mechanisms of disease in SLE. Examples include genes important for DNA damage repair (e.g., TREX1), nucleic acid sensing and type I interferon overproduction (e.g., STING, TREX1), apoptosis (FASLG), tolerance (PRKCD), and clearance of self-antigen (DNASE1L3). Further study of monogenic lupus may lead to better genotype/phenotype correlations in SLE. Eventually, the ability to understand individual patients according to their genetic profile may allow the development of more targeted and personalized approaches to therapy.

H syndrome is an autosomal recessive histiocytosis with multisystemic involvement caused by mutations in the SLC29A3 gene. The term H syndrome was coined to denote the major clinical findings which include hyperpigmentation, hypertrichosis, hearing loss, hepatosplenomegaly, hypogonadism, hyperglycemia/diabetes mellitus and hallux valgus/flexion contractures. Almost 100 individuals affected with this disorder have been reported, however, a thorough evaluation of the ophthalmologic features of H syndrome has not yet been performed. Ophthalmic examination of a 50-year-old male with H syndrome. Mutation analysis of SLC29A3 was also performed in this patient. Ophthalmic findings included; shallow orbits with exorbitism, bilateral pterygium, limbal thickening, corneal arcus and cortical cataract. We also review ophthalmologic findings in previously reported H syndrome patients. The presence of dilated lateral scleral vessels, corneal arcus and shallow orbits should raise the suspicion of H syndrome, especially when seen in young age.

Behçet's disease.

Saadoun, David; Wechsler, Bertrand

2012-04-12

DEFINITION OF THE DISEASE: Behçet disease (BD) is a chronic, relapsing, multisystemic disorder characterized by mucocutaneous, ocular, vascular and central nervous system manifestations. BD seems to cluster along the ancient Silk Road, which extends from eastern Asia to the Mediterranean basin. European cases are often described, not exclusively in the migrant population. The clinical spectrum includes oral and genital ulcerations, uveitis, vascular, neurological, articular, renal and gastrointestinal manifestations. The etiopathogenesis of the disease remains unknown, although genetic predisposition, environmental factors and immunological abnormalities have been implicated. Diagnosis is only based on clinical criteria. DIFFERRENTIAL DIAGNOSIS: It depends on the clinical presentation of BD, but sarcoidosis, multiple sclerosis, Crohn's disease, Takayasu's arteritis, polychondritis or antiphospholipid syndrome need to be considered. Treatment is symptomatic using steroids and immunomodulatory therapy. It is efficient depending on the rapidity of initiation, the compliance, and the duration of therapy. The prognosis is severe due to the ocular, neurological and arterial involvement.

Giant multilevel thoracic hemangioma with spinal cord compression in a patient with Klippel-Weber-Trenaunay syndrome: case report.

Case report and clinical discussion. We intend to report a very rare case of a giant spinal hemangioma causing myelopathy. Multilevel symptomatic spinal hemangiomas causing acute neurologic symptoms are rare disorders. We found only sporadic reports in English literature. We describe a very rare case in which Klippel-Trenaunay-Weber syndrome is associated with a multisegmental vertebral hemangioma causing a rapidly progressing thoracic myelopathy. Because of the extension of the disease, surgical intervention was not feasible, the patient was treated by radiotherapy. The patient showed a complete regression of symptoms with stable condition after 3 months. In extensive spinal hemangiomas, radiotherapy may represent a safe treatment modality with rapid clinical improvement even in cases with spinal cord compression. This report contributes to a wide range of known vascular abnormalities in Klippel-Trenaunay-Weber syndrome and supports the need for a careful multisystemic evaluation of these patients.

Behçet's disease (BD) is a multisystem disorder. The main pathology in BD is vasculitis that involves arteries and veins of all calibers. Central nervous system involvement occurs in 5-10% of patients. Increased morbidity and mortality is rarely observed in children. The mean age at onset in pediatric BD is approximately 7 years. Neurologic involvement in BD is usually observed after 3-6 years. We report the case of a four-year-old Turkish boy with BD with sagittal sinus thrombosis treated with infliximab. The patient presented papilledema without neurologic signs. Although long-term efficacy evaluations are needed in this case, infliximab therapy may be a good option in childhood BD with refractory sinus thrombosis. This is the youngest case of BD with sagittal sinus thrombosis reported so far. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.

Heritable connective tissue disorders (HCTD) present with a wide array of findings, including headache. Because of their unusual substrate, headaches in HCTD can derive from both common and uncommon circumstances. Literature review. Ehlers-Danlos hypermobile type can be recognized by multiple joint findings and its tendency to progress to a multisystem chronic pain syndrome. Ehlers-Danlos classic type also manifests joint laxity and similar pain complaints, but is differentiated by its skin laxity and fragility. Ehlers-Danlos vascular type presents the most severe risk due to blood vessel and hollow organ rupture. Marfan syndrome demonstrates skeletal abnormalities, lens dislocations, and aortic root dilation that can result in dissection. In a headache patient, recognizing the presence of an HCTD improves the strategy for diagnosis and management. A brief review of findings related to joints, skin, and arteries may prompt further investigation into the HCTDs. © 2014 American Headache Society.

Her complete clinical work up was done and was started on lipid lowering drug treatment and low calorie diet. She underwent simultaneous bilateral carotid stenting followed by coronary artery bypass surgery at a later date. In the present scenario we want to emphasize the importance of early detection and treatment of individuals with FH, failing of which results in premature and accelerated atherosclerosis causing multisystemic vascular disease with significant morbidity and mortality. Screening of first degree relatives is important owing to the autosomal dominant inheritance pattern of the FH.

Neurofibromatosis type 1 is a complex, multi-system genetic disorder that is associated with an increased prevalence of pheochromocytoma and paraganglioma compared to the general population, 1.0%-5.7% versus 0.2%-0.6%, respectively. A delay in pheochromocytoma and paraganglioma diagnosis or undiagnosed pheochromocytoma and paraganglioma, as seen in normotensive and asymptomatic patients, may portend a significant morbidity and mortality risk due to excess catecholamine secretion. Currently, there are no generally accepted guidelines of screening for pheochromocytoma and paragangliomas in asymptomatic individuals of this population with approaches and practices varying considerably between physicians. Emerging data suggest benefit in routine pheochromocytoma and paraganglioma screening of all individuals with neurofibromatosis type 1. Herein, we present a case to highlight how routine case detection screening would have identified pheochromocytoma earlier in an active duty military member.

Learning from Job: A Rare Genetic Disease and Lessons of Biblical Proportions.

Dominant negative mutations in STAT3, a critical signaling molecule and transcription factor in multiple organ systems, lead to a rare monogenic disease called the STAT3 loss-of-function, autosomal dominant hyper-IgE syndrome (STAT3LOF AD-HIES). The original name for this syndrome, Job's syndrome, was derived from the observation that patients had a propensity to develop skin boils, reminiscent of the affliction cast upon the biblical Job. Many fascinating observations have been made regarding the pathogenesis of the disease and the role STAT3 plays in human health and disease. Additionally, quite a few phenotypic descriptions from the Book of Job are similar to those seen in patients with STAT3LOF AD-HIES, beyond just the boils. This complex multisystem genetic disorder is a challenge clinically and scientifically, but it also brings into question how we approach genetic syndromes beyond just the technical aspects of research and treatment.

Prader-Willi Syndrome: Clinical Aspects

2012-01-01

Prader-Willi Syndrome (PWS) is a complex multisystem genetic disorder that shows great variability, with changing clinical features during a patient's life. The syndrome is due to the loss of expression of several genes encoded on the proximal long arm of chromosome 15 (15q11.2–q13). The complex phenotype is most probably caused by a hypothalamic dysfunction that is responsible for hormonal dysfunctions and for absence of the sense of satiety. For this reason a Prader-Willi (PW) child develops hyperphagia during the initial stage of infancy that can lead to obesity and its complications. During infancy many PW child display a range of behavioural problems that become more noticeable in adolescence and adulthood and interfere mostly with quality of life. Early diagnosis of PWS is important for effective long-term management, and a precocious multidisciplinary approach is fundamental to improve quality of life, prevent complications, and prolong life expectancy.

A comprehensive team approach to the management of patients with Prader-Willi syndrome.

PubMed

Eiholzer, Urs; Whitman, Barbara Y

2004-09-01

Prader-Willi syndrome (PWS) is a genetic disorder characterized by extreme obesity accompanied by other, multisystem clinical manifestations encompassing both physical and behavioral/cognitive abnormalities. The multi-dimensional problems of patients with PWS cannot be treated with a single intervention and benefit from a team approach to management to optimize outcomes. Childhood stature below target height and reduced final height are some defining characteristics of PWS, and compelling evidence from growth hormone (GH) treatment trials suggests that hypothalamic GH deficiency exists. Treatment with GH has been shown to increase height velocity in children with PWS, decrease weight-for-height index values and body fat mass, and have a positive effect on lean body mass during at least the first year of therapy. In addition to medical concerns, the behavioral manifestations, including an uncorrectable deficit in appetite control, and cognitive limitations associated with PWS, require long-term multidisciplinary management.

Tuberous Sclerosis Associated Neuropsychiatric Disorders (TAND) and the TAND Checklist

BACKGROUND Tuberous sclerosis complex is a multisystem genetic disorder with a range of physical manifestations that require evaluation, surveillance, and management. Individuals with tuberous sclerosis complex also have a range of behavioral, psychiatric, intellectual, academic, neuropsychologic, and psychosocial difficulties. These may represent the greatest burden of the disease. Around 90% of individuals with tuberous sclerosis complex will have some of these difficulties during their lifetime, yet only about 20% ever receive evaluation and treatment. The Neuropsychiatry Panel at the 2012 Tuberous Sclerosis Complex International Consensus Conference expressed concern about the significant “treatment gap” and about confusion regarding terminology relating to the biopsychosocial difficulties associated with tuberous sclerosis complex. METHODS The Tuberous Sclerosis Complex Neuropsychiatry Panel coined the term TAND—tuberous sclerosis complex-associated neuropsychiatric disorders—to bring together these multidimensional manifestations of the disorder, and recommended annual screening for TAND. In addition, the Panel agreed to develop a TAND Checklist as a guide for screening. RESULTS Here, we present an outline of the conceptualization of TAND, rationale for the structure of the TAND Checklist, and include the full US English version of the TAND Checklist. CONCLUSION We hope that the unified term TAND and the TAND Checklist will raise awareness of the importance of tuberous sclerosis complex-associated neuropsychiatric disorders and of the major burden of disease associated with it, provide a shared language and a simple tool to describe and evaluate the different levels of TAND, alert clinical teams and families or individuals of the importance of screening, assessment, and treatment of TAND, and provide a shared framework for future studies of tuberous sclerosis complex-associated neuropsychiatric disorders.

Hyperinsulinemic hypoglycemia (HI) and congenital polycystic kidney disease (PKD) are rare, genetically heterogeneous disorders. The co-occurrence of these disorders (HIPKD) in 17 children from 11 unrelated families suggested an unrecognized genetic disorder. Whole-genome linkage analysis in five informative families identified a single significant locus on chromosome 16p13.2 (logarithm of odds score 6.5). Sequencing of the coding regions of all linked genes failed to identify biallelic mutations. Instead, we found in all patients a promoter mutation (c.-167G>T) in the phosphomannomutase 2 gene ( PMM2 ), either homozygous or in trans with PMM2 coding mutations. PMM2 encodes a key enzyme in N-glycosylation. Abnormal glycosylation has been associated with PKD, and we found that deglycosylation in cultured pancreatic β cells altered insulin secretion. Recessive coding mutations in PMM2 cause congenital disorder of glycosylation type 1a (CDG1A), a devastating multisystem disorder with prominent neurologic involvement. Yet our patients did not exhibit the typical clinical or diagnostic features of CDG1A. In vitro, the PMM2 promoter mutation associated with decreased transcriptional activity in patient kidney cells and impaired binding of the transcription factor ZNF143. In silico analysis suggested an important role of ZNF143 for the formation of a chromatin loop including PMM2 We propose that the PMM2 promoter mutation alters tissue-specific chromatin loop formation, with consequent organ-specific deficiency of PMM2 leading to the restricted phenotype of HIPKD. Our findings extend the spectrum of genetic causes for both HI and PKD and provide insights into gene regulation and PMM2 pleiotropy. Copyright © 2017 by the American Society of Nephrology.

The mitochondrial myopathy encephalopathy, lactic acidosis with stroke-like episodes (MELAS) syndrome: a review of treatment options.

PubMed

Scaglia, Fernando; Northrop, Jennifer L

2006-01-01

Mitochondrial encephalomyopathies are a multisystemic group of disorders that are characterised by a wide range of biochemical and genetic mitochondrial defects and variable modes of inheritance. Among this group of disorders, the mitochondrial myopathy, encephalopathy, lactic acidosis with stroke-like episodes (MELAS) syndrome is one of the most frequently occurring, maternally inherited mitochondrial disorders. As the name implies, stroke-like episodes are the defining feature of the MELAS syndrome, often occurring before the age of 15 years. The clinical course of this disorder is highly variable, ranging from asymptomatic, with normal early development, to progressive muscle weakness, lactic acidosis, cognitive dysfunction, seizures, stroke-like episodes, encephalopathy and premature death. This syndrome is associated with a number of point mutations in the mitochondrial DNA, with over 80% of the mutations occurring in the dihydrouridine loop of the mitochondrial transfer RNA(Leu(UUR)) [tRNA(Leu)((UUR))] gene. The pathophysiology of the disease is not completely understood; however, several different mechanisms are proposed to contribute to this disease. These include decreased aminoacylation of mitochondrial tRNA, resulting in decreased mitochondrial protein synthesis; changes in calcium homeostasis; and alterations in nitric oxide metabolism. Currently, no consensus criteria exist for treating the MELAS syndrome or mitochondrial dysfunction in other diseases. Many of the therapeutic strategies used have been adopted as the result of isolated case reports or limited clinical studies that have included a heterogeneous population of patients with the MELAS syndrome, other defects in oxidative phosphorylation or lactic acidosis due to disorders of pyruvate metabolism. Current approaches to the treatment of the MELAS syndrome are based on the use of antioxidants, respiratory chain substrates and cofactors in the form of vitamins; however, no consistent benefits have been observed with these treatments.

Hypokalemic periodic paralysis (HPP) is a rare disorder characterised by acute, potentially fatal atacks of muscle weakness or paralysis. Massive shift of potassium into cells is caused by elevated levels of insulin and catecholamines in the blood. Hypophosphatemia and hypomagnesemia may be also present. Acidobasic status usually is not impaired. HPP occurs as familiar (caused by ion channels inherited defects) or acquired (in patients with hyperthyroidism). On the basis of two clinical cases we present a review of hypokalemic periodic paralysis in hyperthyroid patients. We discuss patogenesis, clinical and laboratory findings as well as the principles of prevention and treatment of this rare disorder.

A review of eating disorders in males.

2014-11-01

Research in eating disorders in males has been active lately compared to the past. This review aims to provide an overview of the recently published studies of eating disorders in males. Publication of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition has outlined more sex-neutral diagnostic criteria for eating disorders. Data of socioeconomic factors, prenatal influences, clinical characteristics, assessment, and mortality for eating disorders have been reported independently for males. Unlike in females, higher parental education showed no association with eating disorders in males, but twin or triplet status and lower gestational age at birth had an independent association with anorexia nervosa in males. Contrary to earlier suggestions, no differences in eating disorder symptoms such as binging, vomiting, or laxative abuse were observed between the sexes. Yet, males tended to score lower on eating disorder symptom measures than females. High rates of premorbid overweight and higher BMIs at various stages of eating disorders have been confirmed repeatedly. Higher age and lower BMI at admission, and restrictive anorexia nervosa subtype predicted fatal outcome for anorexia nervosa in males. Contemporary research provides grounds for improved recognition, diagnosis, and treatment for males suffering from eating disorders.

Anxiety has been linked to onset of cardiovascular disease. This study examines the differential impact of types of anxiety (panic, phobia and worry) on 3-year onset of non-fatal cardiovascular disease (CVD). By investigating anxiety disorders as opposed to anxiety symptoms and by using a reliable diagnostic instrument to assess anxiety, limitations of previous studies are considered. 5149 persons at risk for CVD were interviewed using the Composite International Diagnostic Interview. The panic-type included panic disorder and panic attacks; the phobic-type included agoraphobia and social phobia, and the worry-type included generalized anxiety disorder. CVD was self-reported and required treatment or monitoring by a doctor. Analyses were adjusted for sociodemographics, behavioral variables, and comorbid somatic and psychiatric disorders. During follow-up, 62 persons (1.2%) developed CVD. Baseline generalized anxiety disorder was strongly associated with onset of CVD (adjusted OR: 3.39). Further research should replicate findings and focus on biological underpinnings of this association. Copyright © 2014 Elsevier Ltd. All rights reserved.

[Metabolic alkalosis despite hyperlactatemia and hypercapnia. Interpretation and therapy with help of the Stewart concept].

Chappell, D; Hofmann-Kiefer, K; Jacob, M; Conzen, P; Rehm, M

2008-02-01

Acid-base disturbances are commonly found in critically ill patients and are often associated with fatal complications. The basis of a successful treatment is a thorough understanding of the causes of these disorders. The "classical methods" to explain acid-base disorders--pH, base excess and bicarbonate concentration--mostly do not provide a causal correlation to the underlying pathology. An unusual case of a combined respiratory-metabolic disorder with hyperlactatemia and hypercapnia is presented. An acidosis masked by hypochloremic and hypoalbuminemic alkalosis was identified with the help of Stewart's concept and finally permitted a successful therapy. The modern Stewart concept provides enhanced information, enabling an exact diagnosis and causal therapy even in complex cases.

Is It Feasible to Identify Natural Clusters of TSC-Associated Neuropsychiatric Disorders (TAND)?

PubMed

2018-04-01

Tuberous sclerosis complex (TSC) is a genetic disorder with multisystem involvement. The lifetime prevalence of TSC-Associated Neuropsychiatric Disorders (TAND) is in the region of 90% in an apparently unique, individual pattern. This "uniqueness" poses significant challenges for diagnosis, psycho-education, and intervention planning. To date, no studies have explored whether there may be natural clusters of TAND. The purpose of this feasibility study was (1) to investigate the practicability of identifying natural TAND clusters, and (2) to identify appropriate multivariate data analysis techniques for larger-scale studies. TAND Checklist data were collected from 56 individuals with a clinical diagnosis of TSC (n = 20 from South Africa; n = 36 from Australia). Using R, the open-source statistical platform, mean squared contingency coefficients were calculated to produce a correlation matrix, and various cluster analyses and exploratory factor analysis were examined. Ward's method rendered six TAND clusters with good face validity and significant convergence with a six-factor exploratory factor analysis solution. The "bottom-up" data-driven strategies identified a "scholastic" cluster of TAND manifestations, an "autism spectrum disorder-like" cluster, a "dysregulated behavior" cluster, a "neuropsychological" cluster, a "hyperactive/impulsive" cluster, and a "mixed/mood" cluster. These feasibility results suggest that a combination of cluster analysis and exploratory factor analysis methods may be able to identify clinically meaningful natural TAND clusters. Findings require replication and expansion in larger dataset, and could include quantification of cluster or factor scores at an individual level. Copyright © 2018 Elsevier Inc. All rights reserved.

There is a known high prevalence of genetic and clinical syndrome diagnoses in the paediatric cardiac population. These disorders often have multisystem effects, which may have an important impact on neurodevelopmental outcomes. Taken together, these facts suggest that patients and families may benefit from consultation by genetic specialists in a cardiac neurodevelopmental clinic. This study assessed the burden of genetic disorders and utility of genetics evaluation in a cardiac neurodevelopmental clinic. A retrospective chart review was conducted of patients evaluated in a cardiac neurodevelopmental clinic from 6 December, 2011 to 16 April, 2013. All patients were seen by a cardiovascular geneticist with genetic counselling support. A total of 214 patients were included in this study; 64 of these patients had a pre-existing genetic or syndromic diagnosis. Following genetics evaluation, an additional 19 were given a new clinical or laboratory-confirmed genetic diagnosis including environmental such as teratogenic exposures, malformation associations, chromosomal disorders, and single-gene disorders. Genetic testing was recommended for 112 patients; radiological imaging to screen for congenital anomalies for 17 patients; subspecialist medical referrals for 73 patients; and non-genetic clinical laboratory testing for 14 patients. Syndrome-specific guidelines were available and followed for 25 patients with known diagnosis. American Academy of Pediatrics Red Book asplenia guideline recommendations were given for five heterotaxy patients, and family-based cardiac screening was recommended for 23 families affected by left ventricular outflow tract obstruction. Genetics involvement in a cardiac neurodevelopmental clinic is helpful in identifying new unifying diagnoses and providing syndrome-specific care, which may impact the patient's overall health status and neurodevelopmental outcome.

Fatal case of ectopic enterobiasis: Enterobius vermicularis in the kidneys.

PubMed

Serpytis, Mindaugas; Seinin, Dmitrij

2012-02-01

Enterobius vermicularis is one of the most common intestinal parasites found in humans. They commonly infest the terminal ileum and large intestine, and are usually considered an innocuous parasite that can be easily eradicated with proper treatment. However, extraintestinal migration of worms, although very rare, may lead to severe health disorders or even death. This article, reports the first fatal case of ectopic enterobiasis known to the authors, which developed in an adult patient with E. vermicularis infection, causing perforation of the large intestine and generalized bacterial peritonitis. Despite emergency laparotomy, the patient died from septic shock on the day after surgery. During pathological examination, worms were found not only in the large intestine, but also in the renal parenchyma; worm eggs were found deposited in the lungs as well.

Fatal hypertriglyceridaemia, acute pancreatitis and diabetic ketoacidosis possibly induced by quetiapine.

A 27-year-old man treated with quetiapine for anxiety disorder developed hypertriglyceridaemia-induced acute pancreatitis and diabetic ketoacidosis. He was otherwise physically healthy with no family history of hyperlipidaemia. Despite aggressive intensive therapy he died of multiorgan failure within 36 h from initial presentation. While second-generation antipsychotics are well known to be causally linked to diabetes and hyperlipidaemia, this is to my knowledge the first-described case of a fatal triad of extreme hypertriglyceridaemia, acute pancreatitis and diabetic ketoacidosis possibly induced by quetiapine. Clinicians should be aware of this rare clinical presentation since rapid progression to multiorgan failure can occur. Early supportive therapy should be initiated. Lactescent serum and ketoacidosis in severe acute pancreatitis should not be overlooked-initiate insulin therapy and possibly plasmapheresis in case of extreme hypertriglyceridaemia.

2018-05-31

Family members grieving the traumatic death of a loved one, as in cases of homicide, suicide, and fatal accidents, are at risk for a number of trauma and bereavement-related mental health problems, including posttraumatic stress disorder (PTSD), depression, prolonged grief disorder, and suicidal ideation (SI). The purpose of this study was to examine the prevalence and correlates of SI among a sample of 130 treatment-seeking traumatically bereaved family members. Adults seeking treatment at two clinics on the US West Coast were assessed for SI, clinical outcomes, and death-related characteristics. Overall, 42% of traumatically bereaved family members endorsed some form of active or passive SI on the Beck Depression Inventory suicide item. The type of loss experienced (i.e., homicide, suicide, fatal accident) was not associated with SI. Although individuals with SI reported more severe symptoms across all clinical outcomes, avoidance (OR = 2.22) and depression (OR = 1.16) were uniquely associated with SI even after adjusting for PTSD-related intrusions and hyperarousal. Results should be interpreted in light of limitations associated with cross-sectional data and a single-item outcome of SI. Routine screening for SI should be standard practice for providers working with traumatically bereaved families.

Rat-bite fever in children: case report and review.

We report 2 cases of rat-bite fever (RBF), a multisystem zoonosis, in children and review the literature. RBF is caused by I of 2 Gram-negative organisms: Streptobacillus moniliformis or, less commonly, Spirillum minus. Both of our cases developed in school-aged girls with a history of rat exposure who presented with a multisystem illness consisting of fever, petechial and purpuric rash, arthralgia and polyarthritis. Both responded promptly to antibiotic treatment. An additional 10 cases from a MEDLINE review (1960-2000) are reviewed. RBF must be included in the differential diagnosis of febrile patients with rashes and a history of exposure to rats.

This article explicates a vision for social change throughout multiple levels of society necessary to eliminate sexual orientation health disparities in youths. We utilized the framework of Bronfenbrenner’s ecological theory of development, a multisystemic model of development that considers direct and indirect influences of multiple levels of the environment. Within this multisystem model we discuss societal and political influences, educational systems, neighborhoods and communities, romantic relationships, families, and individuals. We stress that continued change toward equity in the treatment of lesbian, gay, and bisexual youths across these levels will break down the barriers for these youths to achieve healthy development on par with their heterosexual peers.

Nursing Integration and Innovation Across a Multisystem Enterprise: Priorities for Nurse Leaders.

PubMed

Pappas, Sharon; McCauley, Linda

There is no escaping the fact that the ability to skillfully influence change is a requirement for nurse leaders. This need is intensified as the national health care system reforms and as the morphology of health care systems continues to change, especially in academic health care systems. The purpose of this article was 2-fold. The first objective was to relay the experience of the integration of nursing practice, education, and research within an academic health care system. The second was to, through this story of integration, expose the uniqueness and importance of nurse leader roles influencing innovation across a multisystem enterprise to fulfill the organization's mission.

2017-01-01

Amyotrophic lateral sclerosis (ALS) is considered a multifactorial, multisystem disease in which inflammation and the immune system play important roles in development and progression. The pleiotropic cytokine TNFα is one of the major players governing the inflammation in the central nervous system and peripheral districts such as the neuromuscular and immune system. Changes in TNFα levels are reported in blood, cerebrospinal fluid, and nerve tissues of ALS patients and animal models. However, whether they play a detrimental or protective role on the disease progression is still not clear. Our group and others have recently reported opposite involvements of TNFR1 and TNFR2 in motor neuron death. TNFR2 mediates TNFα toxic effects on these neurons presumably through the activation of MAP kinase-related pathways. On the other hand, TNFR2 regulates the function and proliferation of regulatory T cells (Treg) whose expression is inversely correlated with the disease progression rate in ALS patients. In addition, TNFα is considered a procachectic factor with a direct catabolic effect on skeletal muscles, causing wasting. We review and discuss the role of TNFα in ALS in the light of its multisystem nature. PMID:29081600

Suicide and other causes of mortality in bipolar disorder: a longitudinal study.

The high risk of suicide in bipolar disorder is well recognized, but may have been overestimated. There is conflicting evidence about deaths from other causes and little known about risk factors for suicide. We aimed to estimate suicide and mortality rates in a cohort of bipolar patients and to identify risk factors for suicide. All patients who presented for the first time with a DSM-IV diagnosis of bipolar I disorder in a defined area of southeast London over a 35-year period (1965-1999) were identified. Mortality rates were compared with those of the 1991 England and Wales population, indirectly standardized for age and gender. Univariate and multivariate analyses were used to test potential risk factors for suicide. Of the 239 patients in the cohort, 235 (98.3%) were traced. Forty-two died during the 4422 person-years of follow-up, eight from suicide. The standardized mortality ratio (SMR) for suicide was 9.77 [95% confidence interval (CI) 4.22-19.24], which, although significantly elevated compared to the general population, represented a lower case fatality than expected from previous literature. Deaths from all other causes were not excessive for the age groups studied in this cohort. Alcohol abuse [hazard ratio (HR) 6.81, 95% CI 1.69-27.36, p=0.007] and deterioration from pre-morbid level of functioning up to a year after onset (HR 5.20, 95% CI 1.24-21.89, p=0.024) were associated with increased risk of suicide. Suicide is significantly increased in unselected bipolar patients but actual case fatality is not as high as previously claimed. A history of alcohol abuse and deterioration in function predict suicide in bipolar disorder.

IgE and mast cells in host defense against parasites and venoms

PubMed Central

Mukai, Kaori; Tsai, Mindy; Galli, Stephen J.

2016-01-01

IgE-dependent mast cell activation is a major effector mechanism underlying the pathology associated with allergic disorders. The most dramatic of these IgE-associated disorders is the fatal anaphylaxis which can occur in some people who have developed IgE antibodies to otherwise innocuous antigens, such as those contained in certain foods and medicines. Why would such a highly “maladaptive” immune response develop in evolution, and be retained to the present day? Host defense against parasites has long been considered the only beneficial function that might be conferred by IgE and mast cells. However, recent studies have provided evidence that, in addition to participating in host resistance to certain parasites, mast cells and IgE are critical components of innate (mast cells) and adaptive (mast cells and IgE) immune responses that can enhance host defense against the toxicity of certain arthropod and animal venoms, including enhancing the survival of mice injected with such venoms. Yet, in some people, developing IgE antibodies to insect or snake venoms puts them at risk for having a potentially fatal anaphylactic reaction upon subsequent exposure to such venoms. Delineating the mechanisms underlying beneficial versus detrimental innate and adaptive immune responses associated with mast cell activation and IgE is likely to enhance our ability to identify potential therapeutic targets in such settings, not only for reducing the pathology associated with allergic disorders but perhaps also for enhancing immune protection against pathogens and animal venoms.

Folie à deux in forensic setting.

Kraya, N A; Patrick, C

1997-12-01

This paper is written with the aim of presenting a series of cases of folie à deux, an unusual disorder, occurring in a forensic setting where all the victims suffered a fatal or near-fatal outcome. Similarities in the psychopathology in these cases are drawn and comments are made about their outcome in court. The paper is also written to draw attention to the potential risks involved in this type of case and to accent patterns in psychopathology and in legal outcomes. Five folie à deux cases are described. All are well known to one of the authors (NK), who has treated them at some stage of their illness, provided medicolegal reports for the trial of cases 3, 4 and 5, and provided expert witness testimony in the trial of case 3. All case notes and other relevant documents were studied in detail and a brief summary is provided for each case. The cases appear to conform with the description of folie à deux given in the literature and consist of husband and wife (three cases), mother and daughter (one case) and twin brothers (one case). None of these cases had had any past psychiatric or criminal history, yet all the victims suffered a fatal or near fatal outcome. Additionally, all had shared religious delusions in one form or another. Folie à deux cases with shared religious delusions can be a very high risk and could be potentially fatal in a family setting. The authors also highlight the difficulties inherent in a forensic system restricted to McNaughton rules, particularly when a person is on trial having committed, or being alleged to have committed, a serious offence, and who is found to be suffering from a psychotic illness.

A clinical and molecular review of ubiquitous glucose-6-phosphatase deficiency caused by G6PC3 mutations

PubMed Central

2013-01-01

The G6PC3 gene encodes the ubiquitously expressed glucose-6-phosphatase enzyme (G-6-Pase β or G-6-Pase 3 or G6PC3). Bi-allelic G6PC3 mutations cause a multi-system autosomal recessive disorder of G6PC3 deficiency (also called severe congenital neutropenia type 4, MIM 612541). To date, at least 57 patients with G6PC3 deficiency have been described in the literature. G6PC3 deficiency is characterized by severe congenital neutropenia, recurrent bacterial infections, intermittent thrombocytopenia in many patients, a prominent superficial venous pattern and a high incidence of congenital cardiac defects and uro-genital anomalies. The phenotypic spectrum of the condition is wide and includes rare manifestations such as maturation arrest of the myeloid lineage, a normocellular bone marrow, myelokathexis, lymphopaenia, thymic hypoplasia, inflammatory bowel disease, primary pulmonary hypertension, endocrine abnormalities, growth retardation, minor facial dysmorphism, skeletal and integument anomalies amongst others. Dursun syndrome is part of this extended spectrum. G6PC3 deficiency can also result in isolated non-syndromic severe neutropenia. G6PC3 mutations in result in reduced enzyme activity, endoplasmic reticulum stress response, increased rates of apoptosis of affected cells and dysfunction of neutrophil activity. In this review we demonstrate that loss of function in missense G6PC3 mutations likely results from decreased enzyme stability. The condition can be diagnosed by sequencing the G6PC3 gene. A number of G6PC3 founder mutations are known in various populations and a possible genotype-phenotype relationship also exists. G6PC3 deficiency should be considered as part of the differential diagnoses in any patient with unexplained congenital neutropenia. Treatment with G-CSF leads to improvement in neutrophil numbers, prevents infections and improves quality of life. Mildly affected patients can be managed with prophylactic antibiotics. Untreated G6PC3 deficiency can be fatal. Echocardiogram, renal and pelvic ultrasound scans should be performed in all cases of suspected or confirmed G6PC3 deficiency. Routine assessment should include biochemical profile, growth profile and monitoring for development of varicose veins or venous ulcers. PMID:23758768

Detection of links between Ebola nucleocapsid and virulence using disorder analysis.

2015-08-01

The underlying reasons for the differences in the virulence of various types of Ebola virus (EBOV) remain unknown. Comparison of the percentage of disorder (PID) in nucleocapsid proteins VP30 and NP reveals high correlation between nucleocapsid PIDs and the case-fatality rates of EBOV. The higher disorder of these proteins is likely to be needed for more efficient multiplication of virus copies via more efficient viral RNA transcription and more promiscuous protein binding potential. This is important for the more efficient assistance of nucleocapsid in viral particle budding and of the assembly and mobility of viral proteins across the host membrane and within the cytoplasm. A more comprehensive knowledge of the molecular mechanisms of EBOV virulence would also lead to new and more effective strategies in vaccine development.

GTF2E2 Mutations Destabilize the General Transcription Factor Complex TFIIE in Individuals with DNA Repair-Proficient Trichothiodystrophy

The general transcription factor IIE (TFIIE) is essential for transcription initiation by RNA polymerase II (RNA pol II) via direct interaction with the basal transcription/DNA repair factor IIH (TFIIH). TFIIH harbors mutations in two rare genetic disorders, the cancer-prone xeroderma pigmentosum (XP) and the cancer-free, multisystem developmental disorder trichothiodystrophy (TTD). The phenotypic complexity resulting from mutations affecting TFIIH has been attributed to the nucleotide excision repair (NER) defect as well as to impaired transcription. Here, we report two unrelated children showing clinical features typical of TTD who harbor different homozygous missense mutations in GTF2E2 (c.448G>C [p.Ala150Pro] and c.559G>T [p.Asp187Tyr]) encoding the beta subunit of transcription factor IIE (TFIIEβ). Repair of ultraviolet-induced DNA damage was normal in the GTF2E2 mutated cells, indicating that TFIIE was not involved in NER. We found decreased protein levels of the two TFIIE subunits (TFIIEα and TFIIEβ) as well as decreased phosphorylation of TFIIEα in cells from both children. Interestingly, decreased phosphorylation of TFIIEα was also seen in TTD cells with mutations in ERCC2, which encodes the XPD subunit of TFIIH, but not in XP cells with ERCC2 mutations. Our findings support the theory that TTD is caused by transcriptional impairments that are distinct from the NER disorder XP. PMID:26996949

2003-02-01

Fragile X syndrome, which is produced by mutation of a gene in the X chromosome, is the most frequent cause of hereditary mental retardation. The multisystemic alterations of the disorder are due to the inhibition of the expression of the FMR1 gene and to the lack or absence of FMRP protein. Mental retardation and autistic spectrum constitute the most serious manifestations of the syndrome, but there are numerous neuropsychological disorders that make up the cognitive behavioural (CB) phenotype of patients, and the number of clinical manifestations they are going to present is also high. The aim of the study was to evaluate the parameters that can contribute to the elaboration of a set of generally agreed guidelines that include early diagnosis and the indispensable genetic counselling, as well as a multidisciplinary intervention that contemplates, in a global manner, the medical and educational needs of those affected. The method used to conduct the study involved an analysis of the early manifestations of the disease and the neuropsychological aspects of those affected, by means of a study protocol that includes biological and pedagogical data together with batteries of standard tests. Preliminary results confront us with the delay in diagnosis and in genetic counselling because the CB phenotype, in which language disorders were the most constant element, is not taken as being an early sign of the clinical manifestations or as a serious interference factor in the cognitive aspects in the progress of the disease.

Myasthenia and related disorders of the neuromuscular junction.

PubMed

Spillane, Jennifer; Beeson, David J; Kullmann, Dimitri M

2010-08-01

Our understanding of transmission at the neuromuscular junction has increased greatly in recent years. We now recognise a wide variety of autoimmune and genetic diseases that affect this specialised synapse, causing muscle weakness and fatigue. These disorders greatly affect quality of life and rarely can be fatal. Myasthenia gravis is the most common disorder and is most commonly caused by autoantibodies targeting postsynaptic acetylcholine receptors. Antibodies to muscle-specific kinase (MuSK) are detected in a variable proportion of the remainder. Treatment is symptomatic and immunomodulatory. Lambert-Eaton myasthenic syndrome is caused by antibodies to presynaptic calcium channels, and approximately 50% of cases are paraneoplastic, most often related to small cell carcinoma of the lung. Botulism is an acquired disorder caused by neurotoxins produced by Clostridium botulinum, impairing acetylcholine release into the synaptic cleft. In addition, several rare congenital myasthenic syndromes have been identified, caused by inherited defects in presynaptic, synaptic basal lamina and postsynaptic proteins necessary for neuromuscular transmission. This review focuses on recent advances in the diagnosis and treatment of these disorders.

Diencephalic cachexia (DС) is progressive weight loss despite a normal caloric intake and a satisfactory state of health, which is caused by hypothalamic lesions. This is a rare (about 100 cases were reported) and potentially fatal disorder of unknown pathogenesis. At present, there is no effective pharmacological therapy for the disorder. Cachexia may regress only if the tumor reduces in size, therefore the timely diagnosis and treatment are of vital importance for the patient. DС is typical of early childhood, and only a few cases have been reported in adults. We present a rare case of DС in a 24-year-old female with papillary craniopharyngioma.

To report the clinical characteristics and treatment of 3 patients with juvenile xanthogranuloma (JXG). A retrospective review of the medical records of 3 patients with JXG. JXG was characterized by solitary or multiple yellowish cutaneous nodules, or eye involvement . It could also affect pituitary. JXG was easily misdiagnosed as Langerhans cell histiocytosis (LCH). Treatment for JXG was surgical excision of a solitary skin lesion and some cases might be, spontaneous regression. In cases with multisystem involvement, chemotherapy regimens used to treat LCH may be effective. JXG is one of the more common non-Langerhans histiocytic proliferations and is frequently seen in infants and children. LCH-like chemotherapy is effective for patients with symptomatic multisystem JXG.

This study evaluated the economics of Multisystemic Therapy for Child Abuse and Neglect (MST-CAN) by applying the Washington State Institute for Public Policy (WSIPP) cost-benefit model to data from a randomized effectiveness trial with 86 families (Swenson et al. in JFP 24:497-507, 2010b). The net benefit of MST-CAN, versus enhanced outpatient treatment, was $26,655 per family at 16 months post-baseline. Stated differently, every dollar spent on MST-CAN recovered $3.31 in savings to participants, taxpayers, and society at large. Policymakers and public service agencies should consider these findings when making investments into interventions for high-need families involved with child protective services.

The Prader–Willi syndrome (PWS), a rare multisystem genetic disease, leads to severe disabilities, such as morbid obesity, endocrine dysfunctions, psychiatric disorders, and social disturbances. We explored the whole brain of patients with PWS to detect abnormalities that might explain the behavioral and social disturbances, as well as the psychiatric disorders of these patients. Nine patients with PWS (six males, three females; mean age 16.4 years) underwent a positron emission tomography (PET) scan with H215O as a tracer to measure regional cerebral blood flow (rCBF). The images were compared with those acquired from nine controls (six males, three females; mean age 21.2 years). A morphologic magnetic resonance imaging (MRI) was also performed in PWS patients, and their cognitive and behavioral skills were assessed with Wechsler Intelligence Scale for Children III and the Child Behavior Check List (CBCL). The MRI images showed no evident anatomic abnormalities, whereas PET scans revealed hypoperfused brain regions in PWS patients compared with controls, particularly in the anterior cingulum and superior temporal regions. We observed a significant relationship (P<0.05) between rCBF in the hypoperfused regions and CBCL scores. The functional consequences of these perfusion abnormalities in specific brain regions might explain the behavioral and social problems observed in these individuals. PMID:20588317

Endocrine problems in children with Prader-Willi syndrome: special review on associated genetic aspects and early growth hormone treatment

PubMed Central

2012-01-01

Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder characterized by hypothalamic-pituitary dysfunction. The main clinical features include neonatal hypotonia, distinctive facial features, overall developmental delay, and poor growth in infancy, followed by overeating with severe obesity, short stature, and hypogonadism later in development. This paper reviews recent updates regarding the genetic aspects of this disorder. Three mechanisms (paternal deletion, maternal disomy, and deficient imprinting) are recognized. Maternal disomy can arise because of 4 possible mechanisms: trisomy rescue (TR), gamete complementation (GC), monosomy rescue (MR), and postfertilization mitotic nondisjunction (Mit). Recently, TR/GC caused by nondisjunction at maternal meiosis 1 has been identified increasingly, as a result of advanced maternal childbearing age in Korea. We verified that the d3 allele increases the responsiveness of the growth hormone (GH) receptor to endogenous GH. This paper also provides an overview of endocrine dysfunctions in children with PWS, including GH deficiency, obesity, sexual development, hypothyroidism, and adrenal insufficiency, as well as the effects of GH treatment. GH treatment coupled with a strictly controlled diet during early childhood may help to reduce obesity, improve neurodevelopment, and increase muscle mass. A more active approach to correct these hormone deficiencies would benefit patients with PWS. PMID:22844316

CHIME syndrome is an extremely rare autosomal recessive multisystemic disorder caused by mutations in PIGL. PIGL is an endoplasmic reticulum localized enzyme that catalyzes the second step of glycosylphosphatidylinositol (GPI) biosynthesis, which plays a role in the anchorage of cell-surface proteins including receptors, enzymes, and adhesion molecules. Germline mutations in other members of GPI and Post GPI Attachment to Proteins (PGAP) family genes have been described and constitute a group of diseases within the congenital disorders of glycosylation. Patients in this group often present alkaline phosphatase serum levels abnormalities and neurological symptoms. We report a CHIME syndrome patient who harbors a missense mutation c.500T > C (p.Leu167Pro) and a large deletion involving the 5' untranslated region and part of exon 1 of PIGL. In CHIME syndrome, a recurrent missense mutation c.500T > C (p.Leu167Pro) is found in the majority of patients, associated with a null mutation in the other allele, including an overrepresentation of large deletions. The latter are not detected by the standard analysis in sequencing techniques, including next-generation sequencing. Thus, in individuals with a clinical diagnosis of CHIME syndrome in which only one mutation is found, an active search for a large deletion should be sought.

Alpers-Huttenlocher syndrome (AHS) is a very rare autosomal recessive disorder. AHS is caused by homozygous or compound heterozygous mutations in the nuclear gene encoding mitochondrial DNA polymerase gamma (POLG, chromosome 15q25). Most patients become symptomatic before the age of 2 years. We report 3 patients who were treated in our clinic between 2007 and 2010. All patients suffered from myoclonic seizures and had at least one refractory convulsive status which led to the diagnosis. All of them had varying degrees of developmental delay, 2 of them additionally ataxia. Gastrointestinal motility problems were severe in all patients despite only mildly deranged liver function. While in most aspects our patients present with typical AHS features, they also share intestinal problems, a feature that has not been recognized as typical for AHS before. AHS is a multisystem disorder that does affect all cell systems. Liver and brain are organs with the highest energy demand and are therefore usually affected early in the disease course of AHS. However, constipation and bowel obstruction should be regarded as typical complications in AHS and patients should be monitored and treated to improve quality of life. Regarding treatment options for epilepsy in AHS ketogenic diet as well as lacosamide might be considered. © Georg Thieme Verlag KG Stuttgart · New York.

Pearson marrow-pancreas syndrome is a multisystem mitochondrial disorder characterized by bone marrow failure and pancreatic insufficiency. Children who survive the severe bone marrow dysfunction in childhood develop Kearns-Sayre syndrome later in life. Here we report on four new cases with this condition and define their biochemical abnormalities. Three out of four patients presented with failure to thrive, with most of them having normal development and head size. All patients had evidence of bone marrow involvement that spontaneously improved in three out of four patients. Unique findings in our patients were acute pancreatitis (one out of four), renal Fanconi syndrome (present in all patients, but symptomatic only in one), and an unusual organic aciduria with 3-hydroxyisobutyric aciduria in one patient. Biochemical analysis indicated low levels of plasma citrulline and arginine, despite low-normal ammonia levels. Regression analysis indicated a significant correlation between each intermediate of the urea cycle and the next, except between ornithine and citrulline. This suggested that the reaction catalyzed by ornithine transcarbamylase (that converts ornithine to citrulline) might not be very efficient in patients with Pearson syndrome. In view of low-normal ammonia levels, we hypothesize that ammonia and carbamylphosphate could be diverted from the urea cycle to the synthesis of nucleotides in patients with Pearson syndrome and possibly other mitochondrial disorders. © 2015 Wiley Periodicals, Inc.

Cerebro-retinal microangiopathy with calcifications and cysts (CRMCC) or Coats plus syndrome is a pleiotropic disorder affecting the eyes, brain, bone and gastrointestinal tract. Its primary pathogenesis involves small vessel obliterative microangiopathy. Recently, autosomal recessively inherited mutations in CTC1 have been reported in CRMCC patients. We herein report an adolescent referred to our hospital following new seizures in a context of an undefined multisystem disorder. Cerebral imaging disclosed asymmetrical leukopathy, intracranial calcifications and cysts. In addition, he presented other typical CRMCC features i.e. a history of intrauterine growth retardation, skeletal demineralization and osteopenia, bilateral exudative vitreo-retinopathy reminiscent of Coats disease, recurrent gastrointestinal hemorrhages secondary to watermelon stomach and variceal bleeding of the esophagus due to idiopathic portal hypertension and telangiectatic and angiodysplasic changes in the small intestine and colon, and anemia due to recurrent bleeding and bone marrow abnormalities. The patient was diagnosed with Coats plus syndrome. CTC1 gene screening confirmed the diagnosis with the identification of heterozygous deleterious mutations. CRMCC due to CTC1 mutations has a broad clinical expressivity. Our case report illustrates the main possible associated phenotypes and their complications, demonstrating the need for a careful etiological search in order to initiate appropriate therapeutic and preventive measures.

Diagnosing cardiovascular disease from the perspective of the brain and inflammation.

Numerous lifestyle, emotional, and biological factors have been identified as risk factors for heart disease. These include socioeconomic status, early childhood and intimate partner abuse, disruption of sleep patterns, lack of exercise, and unhealthy food choices. Genetic and epigenetic factors are also critical components of the equation. A common denominator that links directly or indirectly all of these factors is inflammation. In some instances, the production of inflammatory molecules may precipitate the illness, while in others they may be produced in response to the underlying cause. Regardless of whether through direct or indirect means, inflammation contributes to the gradual loss of cellular energy substrates, which culminates in impaired diastolic performance. For that reason, to refer to a failure of the cardiovascular system as heart or cardiovascular disease lessens the potentially important contribution of a myriad of other factors. This article begins with the premise that impaired cardiac functioning is more than a heart disorder. An argument will be made that impaired cardiac functioning can also be an economic, behavioral, and/or emotional disorder, which subsequently gives rise to a metabolic failure. Therefore, a multi-systems approach should be taken to identify prior to the onset of damage biological and non-biological predictors of impending heart disease.

Pre-eclampsia part 1: current understanding of its pathophysiology

Pre-eclampsia is characterized by new-onset hypertension and proteinuria at ≥20 weeks of gestation. In the absence of proteinuria, hypertension together with evidence of systemic disease (such as thrombocytopenia or elevated levels of liver transaminases) is required for diagnosis. This multisystemic disorder targets several organs, including the kidneys, liver and brain, and is a leading cause of maternal and perinatal morbidity and mortality. Glomeruloendotheliosis is considered to be a characteristic lesion of pre-eclampsia, but can also occur in healthy pregnant women. The placenta has an essential role in development of this disorder. Pathogenetic mechanisms implicated in pre-eclampsia include defective deep placentation, oxidative and endoplasmic reticulum stress, autoantibodies to type-1 angiotensin II receptor, platelet and thrombin activation, intravascular inflammation, endothelial dysfunction and the presence of an antiangiogenic state, among which an imbalance of angiogenesis has emerged as one of the most important factors. However, this imbalance is not specific to pre-eclampsia, as it also occurs in intrauterine growth restriction, fetal death, spontaneous preterm labour and maternal floor infarction (massive perivillous fibrin deposition). The severity and timing of the angiogenic imbalance, together with maternal susceptibility, might determine the clinical presentation of pre-eclampsia. This Review discusses the diagnosis, classification, clinical manifestations and putative pathogenetic mechanisms of pre-eclampsia. PMID:25003615

Psychostimulants and Movement Disorders

Psychostimulants are a diverse group of substances with their main psychomotor effects resembling those of amphetamine, methamphetamine, cocaine, or cathinone. Due to their potential as drugs of abuse, recreational use of most of these substances is illegal since 1971 Convention on Psychotropic Substances. In recent years, new psychoactive substances have emerged mainly as synthetic cathinones with new molecules frequently complementing the list. Psychostimulant related movement disorders are a known entity often seen in emergency rooms around the world. These admissions are becoming more frequent as are fatalities associated with drug abuse. Still the legal constraints of the novel synthetic molecules are bypassed. At the same time, chronic and permanent movement disorders are much less frequently encountered. These disorders frequently manifest as a combination of movement disorders. The more common symptoms include agitation, tremor, hyperkinetic and stereotypical movements, cognitive impairment, and also hyperthermia and cardiovascular dysfunction. The pathophysiological mechanisms behind the clinical manifestations have been researched for decades. The common denominator is the monoaminergic signaling. Dopamine has received the most attention but further research has demonstrated involvement of other pathways. Common mechanisms linking psychostimulant use and several movement disorders exist.

Congenital myasthenic syndromes are a heterogeneous group of inherited disorders that arise from impaired signal transmission at the neuromuscular synapse. They are characterized by fatigable muscle weakness. We performed linkage analysis, whole-exome and whole-genome sequencing to determine the underlying defect in patients with an inherited limb-girdle pattern of myasthenic weakness. We identify ALG14 and ALG2 as novel genes in which mutations cause a congenital myasthenic syndrome. Through analogy with yeast, ALG14 is thought to form a multiglycosyltransferase complex with ALG13 and DPAGT1 that catalyses the first two committed steps of asparagine-linked protein glycosylation. We show that ALG14 is concentrated at the muscle motor endplates and small interfering RNA silencing of ALG14 results in reduced cell-surface expression of muscle acetylcholine receptor expressed in human embryonic kidney 293 cells. ALG2 is an alpha-1,3-mannosyltransferase that also catalyses early steps in the asparagine-linked glycosylation pathway. Mutations were identified in two kinships, with mutation ALG2p.Val68Gly found to severely reduce ALG2 expression both in patient muscle, and in cell cultures. Identification of DPAGT1, ALG14 and ALG2 mutations as a cause of congenital myasthenic syndrome underscores the importance of asparagine-linked protein glycosylation for proper functioning of the neuromuscular junction. These syndromes form part of the wider spectrum of congenital disorders of glycosylation caused by impaired asparagine-linked glycosylation. It is likely that further genes encoding components of this pathway will be associated with congenital myasthenic syndromes or impaired neuromuscular transmission as part of a more severe multisystem disorder. Our findings suggest that treatment with cholinesterase inhibitors may improve muscle function in many of the congenital disorders of glycosylation.

Bipolar disorder (BD) is a chronic psychiatric disorder that is found within the first ten causes of disability and premature mortality. The metabolic syndrome (MS) is a group of risk factors (RF) that predispose to cardiovascular disease (CV), diabetes and early mortality. Both diseases generate high costs to the health system. Major studies have shown that MS has a higher prevalence in patients with mental disorders compared to the general population. The incidence of MS in BD is multifactorial, and due to iatrogenic, genetic, economic, psychological, and behavioral causes related to the health system. The most common RF found is these patients was an increased abdominal circumference, and it was found that the risk of suffering this disease was greater in women and Hispanic patients. As regards the increase in RF to develop a CV in patients with BD, there have been several explanations based on the risky behavior of patients with mental illness, included tobacco abuse, physical inactivity and high calorie diets. An additional explanation described in literature is the view of BD as a multisystemic inflammatory illness, supported by the explanation that inflammation is a crucial element in atherosclerosis, endothelial dysfunction, platelet rupture, and thrombosis. The pathophysiology of MS and BD include factors such as adrenal, thyroid and sympathetic nervous system dysfunction, as well as poor lifestyle and medication common in these patients. This article attempts to give the reader an overall view of the information published in literature to date, as regards the association between BD and MS.

Effective interventions for maltreated children are impeded by gaps in our knowledge of the etiopathogenic mechanisms leading from maltreatment to mental disorders. Although some studies have already identified individual risk factors, there is a lack of large-scale multilevel research on how psychosocial, neurobiological, and genetic factors act in concert to modulate risk of internalizing psychopathology in childhood following maltreatment. To help close this gap, we aim to delineate gender-specific pathways from maltreatment to psychological disorder/resilience. To this end, we examine the interplay of specific maltreatment characteristics and psychological, endocrine, metabolomic, and (epi-)genomic stress response patterns as well as cognitive-emotional/social processes as determinants of developmental outcome. Specifically, we will explore endocrine, metabolomic, and epigenetic mechanisms leading from maltreatment to a higher risk of depression and anxiety disorders. Four large samples amounting to a total of N = 920 children aged 4-16 years will be assessed: Two cohorts with prior internalizing psychopathology and controls will be checked for maltreatment and two cohorts with substantiated maltreatment will be checked for internalizing (and externalizing) psychopathology. We will apply a multi-source (interview, questionnaires, official records), multi-informant strategy (parents, children, teachers) to assess maltreatment characteristics (e.g., subtypes, developmental timing, chronicity) and psychopathological symptoms, supplemented with multiple measurements of risk and protective factors and cutting-edge laboratory analyses of endocrine, steroid metabolomic and epigenetic factors. As previous assessments in the two largest samples are already available, longitudinal data will be generated within the three year study period. Our results will lay the empirical foundation for (a) detection of early biopsychosocial markers, (b) development of screening measures, and (c) multisystem-oriented interventions in the wake of maltreatment.

Targeting ion channels for the treatment of gastrointestinal motility disorders

Beyder, Arthur

2012-01-01

Gastrointestinal (GI) functional and motility disorders are highly prevalent and responsible for long-term morbidity and sometimes mortality in the affected patients. It is estimated that one in three persons has a GI functional or motility disorder. However, diagnosis and treatment of these widespread conditions remains challenging. This partly stems from the multisystem pathophysiology, including processing abnormalities in the central and peripheral (enteric) nervous systems and motor dysfunction in the GI wall. Interstitial cells of Cajal (ICCs) are central to the generation and propagation of the cyclical electrical activity and smooth muscle cells (SMCs) are responsible for electromechanical coupling. In these and other excitable cells voltage-sensitive ion channels (VSICs) are the main molecular units that generate and regulate electrical activity. Thus, VSICs are potential targets for intervention in GI motility disorders. Research in this area has flourished with advances in the experimental methods in molecular and structural biology and electrophysiology. However, our understanding of the molecular mechanisms responsible for the complex and variable electrical behavior of ICCs and SMCs remains incomplete. In this review, we focus on the slow waves and action potentials in ICCs and SMCs. We describe the constituent VSICs, which include voltage-gated sodium (NaV), calcium (CaV), potassium (KV, KCa), chloride (Cl–) and nonselective ion channels (transient receptor potentials [TRPs]). VSICs have significant structural homology and common functional mechanisms. We outline the approaches and limitations and provide examples of targeting VSICs at the pores, voltage sensors and alternatively spliced sites. Rational drug design can come from an integrated view of the structure and mechanisms of gating and activation by voltage or mechanical stress. PMID:22282704

Yellow fever (YF) is a viral disease endemic to the tropical regions of Africa and South America. An outbreak of YF has been occurring in Angola, since the beginning of 2016. In March 2016, a 32-year-old Chinese man who returned from Angola was hospitalized and diagnosed with the first case of imported YF in China. Clinical observations, blood viral RNA detection, serological testing and treatments for the patient were performed daily. The virus was isolated in Vero cells, and the complete viral genome was sequenced and analyzed using the next-generation genomic sequencing platform. The patient presented with hemorrhagic fever, jaundice and oliguria at day 3 after onset, which rapidly progressed to multisystem organ failure with extremely elevated liver, pancreatic and myocardial enzymes. The patient died despite the intensive supportive treatments that were performed. A liver biopsy showed severe and multilobular necrosis. Viral RNA was detectable throughout the clinical course of the disease. Whole-genomic sequence analysis revealed that the virus belongs to the Angola71 genotype. Although the virus has been circulating in Angola for 45 years, only 14 amino-acid substitutions and no amino-acid changes were observed in the membrane and envelope proteins compared with the virus collected in 1971. The presence of this imported YF case in China indicated that with the increase in business travel among countries, YF outbreaks in Africa can lead to the international spread of the disease. The production and use of YF vaccines is, therefore, an urgent issue. PMID:27406389

Although the virus has been circulating in Angola for 45 years, only 14 amino-acid substitutions and no amino-acid changes were observed in the membrane and envelope proteins compared with the virus collected in 1971. The presence of this imported YF case in China indicated that with the increase in business travel among countries, YF outbreaks in Africa can lead to the international spread of the disease. The production and use of YF vaccines is, therefore, an urgent issue.

Neuroblastoma is a childhood cancer derived from cells of neural crest origin. The hallmarks of its enigmatic character include its propensity for spontaneous regression under some circumstances and its association with paraneoplastic opsoclonus, myoclonus, and ataxia. The neurodevelopmental underpinnings of its origins may provide important clues for development of novel therapeutic and preventive agents for this frequently fatal malignancy and for the associated paraneoplastic syndromes.

This article presents a novel methodology to assess flood risk to people by integrating people's vulnerability and ability to cushion hazards through coping and adapting. The proposed approach extends traditional risk assessments beyond material damages; complements quantitative and semi-quantitative data with subjective and local knowledge, improving the use of commonly available information; produces estimates of model uncertainty by providing probability distributions for all of its outputs. Flood risk to people is modeled using a spatially explicit Bayesian network model calibrated on expert opinion. Risk is assessed in terms of: (1) likelihood of non-fatal physical injury; (2) likelihood of post-traumatic stress disorder; (3) likelihood of death. The study area covers the lower part of the Sihl valley (Switzerland) including the city of Zurich. The model is used to estimate the benefits of improving an existing Early Warning System, taking into account the reliability, lead-time and scope (i.e. coverage of people reached by the warning). Model results indicate that the potential benefits of an improved early warning in terms of avoided human impacts are particularly relevant in case of a major flood event: about 75 % of fatalities, 25 % of injuries and 18 % of post-traumatic stress disorders could be avoided.

[Sudden cardiac death, a major scientific challenge].

Sudden death is responsible for 350,000 deaths each year in Europe, or 1000 deaths each day, equivalent to the combined mortality from the most lethal cancers (breast, lung and colorectal). Unfortunately, sudden death is widely considered to be "natural", being due to unknown but critical cardiac disorders leading to sudden arrest of cardiac activity. Awareness of its potential preventability is inadequate. Indeed, 80% of cases of sudden death are associated with extremely rapid heartbeats, an "electric tornado" called ventricular fibrillation, caused by ultrarapid firing of ectopic foci or chaotic wave propagation. This arrhythmia strikes like lightning Although it can be associated with myocardial infarction, most victims have structurally normal or slightly altered hearts. The cells which cause this ultrarapid firing originate from the Purkinje system, which constitutes just a fraction (2%) of total cardiac mass. This is borne out by the fact that the risk of fatal arrhythmic events can be reduced by focal thermoablation. What is most important is to identify subjects at risk of such events. It has been suggested that there exists an unidentified subclinical electrical disharmony, which converts into a tornado of ultimately fatal clinical events at a certain threshold level. High-resolution bioelectrical cardiac mapping, functional imaging, and treatment of electrical field disorders are major scientific challenges given their complexity, intraindividual dynamics and interindividual variability.

Adverse drug reactions (ADR) are one of the ten main causes of mortality in the world, as a cause of hospital admissions or prolongation hospitalizations days created an important health and economic impact. This study aimed to detect incidence and characterize ADRs that occurred during hospitalization and associated with admission in Internal Medicine service. Observational and prospective study of intensive RAM monitoring patients admitted in Internal Medicine services in a third level hospital over a twelve months period in 2014. The assessment consisted of a complete and protocol collecting information about the patients and related to suspected ADRs during hospitalization. Statistical analysis was performed using SPSS v.20.0. The study included 253 patients and in 54 (21,34%) ADR were detected, the risk of experiencing an ADR was associated with the age (p=0.012). ADR-related hospitalizations incidence were 7,11%, and fatal ADR incidence were 1,97%. With regard to severity 81,2% were severe. Gastrointestinal disorders represented the most common ADRs followed by metabolism and nutrition disorders and vascular disorders. The drugs most frequently associated with ADRs were cardiovascular agents, antiinfective drugs and central nervous system agents. 72.2% of the patients who suffered ADR had polypharmacy. In our study incidence of adverse drug reactions in hospitalized patients was 21,34%, this data and ADR´s related to admission to hospital or fatal ADR´s are mainly suffered by pluripathology and polymedicated elderly patients with worst renal function values. In these patients a more careful prescription should be made.

Rare disease represents one of the most significant issues facing the medical community and health care providers worldwide, yet the majority of these disorders never emerge from their obscurity, drawing little attention from the medical community or the pharmaceutical industry. The challenge therefore is how best to mobilize rare disease stakeholders to enhance basic, translational and clinical research to advance understanding of pathogenesis and accelerate therapy development. Here we describe a rare, fatal brain disorder known as Niemann-Pick type C (NPC) and an innovative research collaborative known as Support of Accelerated Research for NPC (SOAR-NPC) which illustrates one pathway through which knowledge of a rare disease and its possible treatments are being successfully advanced. Use of the "SOAR" mechanism, we believe, offers a blueprint for similar advancement for many other rare disorders.

Cutis laxa is a connective tissue disorder with distinctive lax, redundant, and inelastic skin. It is a genetically heterogenous disorder with autosomal dominant and recessive patterns of inheritance. We report a patient with cutis laxa supported by clinical, microscopic, and ultrastructural findings. Molecular analysis of fibulin-4 and -5, of the α2 subunit of the V-type H+ ATPase, and of the component of the oligomeric Golgi complex 7 (COG7) genes excluded the type I and type II autosomal recessive forms of cutis laxa, and congenital disorders of glycosylation associated with cutis laxa. Remarkably, our patient also presented severe and lethal pulmonary hypertension as a newborn. This case with cutis laxa, severe pulmonary hypertension, and no detectable mutations in fibulin-4 and -5 genes may represent a previously unrecognized syndrome. PMID:21285876

Traumatic spinal cord injury (SCI) often occurs in patients with concurrent traumatic injuries in other body systems. These patients with polytrauma pose unique challenges to clinicians. The current review evaluates existing guidelines and updates the evidence for prehospital transport, immobilization, initial resuscitation, critical care, hemodynamic stability, diagnostic imaging, surgical techniques, and timing appropriate for the patient with SCI who has multisystem trauma. Initial management should be systematic, with focus on spinal immobilization, timely transport, and optimizing perfusion to the spinal cord. There is general evidence for the maintenance of mean arterial pressure of > 85 mm Hg during immediate and acute care to optimize neurological outcome; however, the selection of vasopressor type and duration should be judicious, with considerations for level of injury and risks of increased cardiogenic complications in the elderly. Level II recommendations exist for early decompression, and additional time points of neurological assessment within the first 24 hours and during acute care are warranted to determine the temporality of benefits attributable to early surgery. Venous thromboembolism prophylaxis using low-molecular-weight heparin is recommended by current guidelines for SCI. For these patients, titration of tidal volumes is important to balance the association of earlier weaning off the ventilator, with its risk of atelectasis, against the risk for lung damage from mechanical overinflation that can occur with prolonged ventilation. Careful evaluation of infection risk is a priority following multisystem trauma for patients with relative immunosuppression or compromise. Although patients with polytrauma may experience longer rehabilitation courses, long-term neurological recovery is generally comparable to that in patients with isolated SCI after controlling for demographics. Bowel and bladder disorders are common following SCI, significantly reduce quality of life, and constitute a focus of targeted therapies. Emerging biomarkers including glial fibrillary acidic protein, S100β, and microRNAs for traumatic SCIs are presented. Systematic management approaches to minimize sources of secondary injury are discussed, and areas requiring further research, implementation, and validation are identified.

Niemann-Pick disease type C (NP-C) is a rare multisystemic lysosomal disorder which, albeit treatable, is still starkly underdiagnosed. As NP-C features early onset ataxia (EOA) in 85-90 % of cases, EOA presents a promising target group for undiagnosed NP-C patients. Here, we assessed the ability of the previously established NP-C suspicion index (SI) and a novel abbreviated '2/3 SI' tool for rapid appraisal of suspected NP-C in unexplained EOA. This was a retrospective observational study comparing 'NP-C EOA' cases (EOA patients with confirmed NP-C) with non-NP-C EOA controls (EOA patients negative for NP-C gene mutations). NP-C risk prediction scores (RPS) from both the original and 2/3 SIs were calculated and their discriminatory performance evaluated. Among 133 patients (47 NP-C EOA cases; 86 non-NP-C EOA controls), moderate (40-69 points) and high (≥70 points) RPS were common based on original SI assessments in non-NP-C EOA controls [16 (19 %) and 8 (9 %), respectively], but scores ≥70 points were far more frequent [46 (98 %)] among NP-C EOA cases. RPS cut-off values provided 98 % sensitivity and 91 % specificity for NP-C at 70-point cut-off, and ROC analysis revealed an AUC of 0.982. Using the 2/3 SI, 90 % of NP-C EOA cases had scores of 2 or 3, and RPS analysis showed an AUC of 0.961. In conclusion, the NP-C SI and the new, quick-to-apply 2/3 SI distinguished well between NP-C and non-NP-C patients, even in EOA populations with high background levels of broadly NPC-compatible multisystemic disease features. While the original SI showed the greatest sensitivity, both tools reliably aided identification of patients with unexplained EOA who warranted further investigation for NP-C.

The “First” Case of Cholera in Haiti: Lessons for Global Health

Cholera is an acute watery diarrheal disease caused by infection with Vibrio cholerae. The disease has a high fatality rate when untreated and outbreaks of cholera have been increasing globally in the past decade, most recently in Haiti. We present the case of a 28-year-old Haitian male with a history of severe untreated mental health disorder that developed acute fatal watery diarrhea in mid-October 2010 in central Haiti after drinking from the local river. We believe he is the first or among the first cases of cholera in Haiti during the current epidemic. By reviewing his case, we extracted lessons for global health on the importance of mental health for overall health, the globalization of diseases in small communities, and the importance of a comprehensive approach to the health of communities when planning services in resource-poor settings.

Infantile-onset multisystem neurologic, endocrine, and pancreatic disease (IMNEPD) has been recently linked to biallelic mutation of the peptidyl-tRNA hydrolase 2 gene PTRH2. Two index patients with IMNEPD in the original report had multiple neurological symptoms such as postnatal microcephaly, intellectual disability, developmental delay, sensorineural deafness, cerebellar atrophy, ataxia, and peripheral neuropathy. In addition, distal muscle weakness and abnormalities of thyroid, pancreas, and liver were found. Here, we report five further IMNEPD patients with a different homozygous PTRH2 mutation, broaden the phenotypic spectrum of the disease and differentiate common symptoms and interindividual variability in IMNEPD associated with a unique mutation. We thereby hope to better define IMNEPD and promote recognition and diagnosis of this novel disease entity.

A prospective multi-site study examined organizational climate and structure effects on the behavior and functioning of delinquent youth with and without co-occurring substance treated with an evidence-based treatment for serious antisocial behavior (i.e., Multisystemic Therapy). Participants were 1979 youth treated by 429 therapists across 45 provider organizations in North America. Results of Mixed Effects Regression Models showed some aspects of climate and structure had no effects, some had similar effects, and some had slightly differential and sometimes counter-intuitive effects on the outcomes of these youth. Implications are considered for research to increase the array and availability of effective treatments for youth with co-occurring substance use across service sectors. PMID:22844190

Borrelia burgdorferi, a spirochaete transmitted to human hosts during feeding of infected Ixodes ticks, is the causative agent of Lyme disease, the most frequent vector-borne disease in Eurasia and North America. Sporadically Lyme disease develops into a chronic, multisystemic disorder. Serum-resistant B. burgdorferi strains bind complement factor H (FH) and FH-like protein 1 (FHL-1) on the spirochaete surface. This binding is dependent on the expression of proteins termed complement-regulator acquiring surface proteins (CRASPs). The atomic structure of BbCRASP-1, the key FHL-1/FH-binding protein of B. burgdorferi, has recently been determined. Our analysis indicates that its protein topology apparently evolved to provide a high affinity interaction site for FH/FHL-1 and leads to an atomic-level hypothesis for the functioning of BbCRASP-1. This work demonstrates that pathogens interact with complement regulators in ways that are distinct from the mechanisms used by the host and are thus obvious targets for drug design.

Characterization of the thrombin generation profile in systemic lupus erythematosus.

2017-03-01

Systemic lupus erythematosus (SLE) is a multisystemic inflammatory autoimmune disorder. Thrombotic events occur at a higher incidence among SLE patients. The investigation of thrombin generation (TG) with calibrated automated thrombogram (CAT) test as a global hemostasis assay is applicable for the overall functional assessment of the hemostasis. The aim of this study was to characterize the hemostatic alterations observed in SLE by CAT assay. In this study, CAT parameters and basic coagulation parameters of SLE patients (n = 22) and healthy control subjects (n = 34) were compared. CAT area under the curve (i.e., endogenous thrombin potential) was lower than normal in SLE (807 vs. 1,159 nM*min, respectively), whereas other CAT parameters (peak, lag time, time to peak, and velocity index) and the basic coagulation tests were within the normal range. The presence of anti-phospholipid antibodies and the applied therapy was not associated with hemostasis parameters in SLE. We concluded that the reported high risk of thrombosis is not related to TG potential.

Clinical aspects of autoimmune rheumatic diseases.

Goldblatt, Fiona; O'Neill, Sean G

2013-08-31

Multisystem autoimmune rheumatic diseases are heterogeneous rare disorders associated with substantial morbidity and mortality. Efforts to create international consensus within the past decade have resulted in the publication of new classification or nomenclature criteria for several autoimmune rheumatic diseases, specifically for systemic lupus erythematosus, Sjögren's syndrome, and the systemic vasculitides. Substantial progress has been made in the formulation of new criteria in systemic sclerosis and idiopathic inflammatory myositis. Although the autoimmune rheumatic diseases share many common features and clinical presentations, differentiation between the diseases is crucial because of important distinctions in clinical course, appropriate drugs, and prognoses. We review some of the dilemmas in the diagnosis of these autoimmune rheumatic diseases, and focus on the importance of new classification criteria, clinical assessment, and interpretation of autoimmune serology. In this era of improvement of mortality rates for patients with autoimmune rheumatic diseases, we pay particular attention to the effect of leading complications, specifically cardiovascular manifestations and cancer, and we update epidemiology and prognosis.

In this review, we had pay specific attention on the last discoveries regarding the three cellular components mainly involved in the development and maintenance of CD: T-cells, B-cells, and microbioma. All of them had been showed critical for the interaction between inflammatory immune response and gluten peptides. Although the mechanisms of interaction among overall these components are not yet fully understood, recent proteomics and molecular studies had shed some lights in the pathogenic role of tissue transglutaminase 2 in CD and in the alteration of the intestinal barrier function induced by host microbiota.

Behçet's disease (BD) is a multisystemic disorder that involves vessels of all sizes. Superior vena cava (SVC) thrombosis is a rare complication that can lead to the development of various collateral pathways. A 31-year-old man presented with SVC syndrome. He had a history of recurrent genital aphthosis. Computed tomography revealed extensive thrombosis of the right internal jugular, axillary, and subclavian veins with collateral circulation. The patient was diagnosed with BD, and he was started on anticoagulation and immunosuppressive therapy. One week later, he presented with haematemesis. Upper gastrointestinal endoscopy disclosed varices in the upper third of the oesophagus with stigmata of recent bleeding. Portal hypertension was ruled out. Anticoagulation therapy was discontinued. He was discharged on immunosuppressive therapy. Bleeding from downhill oesophageal varices should be suspected in any patient presenting with upper gastrointestinal bleeding and a history of SVC syndrome due to BD.

Tissue-specific regulation of BMP signaling by Drosophila N-glycanase 1.

Mutations in the human N- glycanase 1 ( NGLY1 ) cause a rare, multisystem congenital disorder with global developmental delay. However, the mechanisms by which NGLY1 and its homologs regulate embryonic development are not known. Here we show that Drosophila Pngl encodes an N -glycanase and exhibits a high degree of functional conservation with human NGLY1. Loss of Pngl results in developmental midgut defects reminiscent of midgut-specific loss of BMP signaling. Pngl mutant larvae also exhibit a severe midgut clearance defect, which cannot be fully explained by impaired BMP signaling. Genetic experiments indicate that Pngl is primarily required in the mesoderm during Drosophila development. Loss of Pngl results in a severe decrease in the level of Dpp homodimers and abolishes BMP autoregulation in the visceral mesoderm mediated by Dpp and Tkv homodimers. Thus, our studies uncover a novel mechanism for the tissue-specific regulation of an evolutionarily conserved signaling pathway by an N -glycanase enzyme.

Spotlight on agalsidase beta in Fabry disease.

PubMed

Keating, Gillian M; Simpson, Dene

2007-01-01

Agalsidase beta (Fabrazyme) is a recombinant human alpha-galactosidase A enzyme approved for intravenous use in the treatment of Fabry disease. Fabry disease is a progressive, multisystemic, potentially life-threatening disorder caused by a deficiency of alpha-galactosidase A. This deficiency results in accumulation of glycosphingolipids, particularly globotriaosylceramide (GL-3), in the lysosomes of various tissues. This accumulation is the underlying driver of disease progression. Agalsidase beta provides an exogenous source of alpha-galactosidase A. Intravenous agalsidase beta is effective and well tolerated in patients with Fabry disease. In a phase III trial, agalsidase beta was shown to clear GL-3 from various target cells and, in a subsequent extension of this trial, prevent GL-3 reaccumulation. In a post-approval trial, agalsidase beta was shown to provide significant clinical benefit by reducing the risk of a major clinical event. Thus, agalsidase beta represents an important advance in the treatment of Fabry disease, and agalsidase beta therapy should be strongly considered in patients with Fabry disease who are suitable candidates.

Anderson-Fabry disease is a hereditary X-linked lysosomal storage disorder caused by a deficiency of the lysosomal enzyme alpha galactosidase A. It results in the accumulation of the glycosphingolypid globotrioasoyl ceramide (Gb3 in different cells and organs, resulting in a multi-system pathology including end organ failure. Patients with Fabry disease present clinically with cardiac, renal and neurological involvement; both life expectancy and quality of life are severely compromised. The current causal treatment for Fabry disease is enzyme replacement therapy (ERT), available since 2001. The two recombinant preparations available for ERT are agalsidase alfa (Replagal) and agalsidase beta (Fabrazyme). They have both been showed to have positive effect on kidney and heart, on the symptoms of pain and quality of life. Few data to date are available on comparison of the two preparations of ERT. This article reviews evidence of the literature and shows our personal experience about the safety and efficacy of ERT.

Mitochondriopathies often present clinically as multisystemic disorders of primarily high-energy consuming organs. Assembly, turnover, and surveillance of mitochondrial proteins are essential for mitochondrial function and a key task of AAA family members of metalloproteases. We identified a homozygous mutation in the nuclear encoded mitochondrial escape 1-like 1 gene YME1L1, member of the AAA protease family, as a cause of a novel mitochondriopathy in a consanguineous pedigree of Saudi Arabian descent. The homozygous missense mutation, located in a highly conserved region in the mitochondrial pre-sequence, inhibits cleavage of YME1L1 by the mitochondrial processing peptidase, which culminates in the rapid degradation of YME1L1 precursor protein. Impaired YME1L1 function causes a proliferation defect and mitochondrial network fragmentation due to abnormal processing of OPA1. Our results identify mutations in YME1L1 as a cause of a mitochondriopathy with optic nerve atrophy highlighting the importance of YME1L1 for mitochondrial functionality in humans.

Steinert’s disease or Myotonic Dystrophy type 1 (DM1) is an autosomal dominant multisystemic disorder characterized by myotonia, muscle and facial weakness, cataracts, cognitive, endocrine and gastrointestinal involvement, and cardiac conduction abnormalities. Although mild myocardial dysfunction may be detected in this syndrome with age, overt myocardial dysfunction with heart failure is not frequent. Cardiac resynchronization therapy is an effective treatment to improve morbidity and reduce mortality in patients with DM1 showing intra-ventricular conduction delay and/or congestive heart failure. We report the case of a patient with Steinert disease showing an early onset ventricular dysfunction due to chronic right ventricular apical pacing, in which an epicardial left ventricular lead implantation was performed following the failure of the percutaneous attempt. As no relief in symptoms of heart failure, nor an improvement of left ventricular ejection fraction and reverse remodelling was observed six months later, the patient was addressed to the heart transplantation.

The present study examines the concept of illness identity, the degree to which a chronic illness is integrated into one's identity, in adults with a chronic illness by validating a new self-report questionnaire, the Illness Identity Questionnaire (IIQ). Self-report questionnaires on illness identity, psychological, and physical functioning were assessed in two samples: adults with congenital heart disease (22-78 year old; n = 276) and with multisystem connective tissue disorders (systemic lupus erythematosus or systemic sclerosis; 17-81 year old; n = 241). The IIQ could differentiate four illness identity states (i.e., engulfment, rejection, acceptance, and enrichment) in both samples, based on exploratory and confirmatory factor analysis. All four subscales proved to be reliable. Rejection and engulfment were related to maladaptive psychological and physical functioning, whereas acceptance and enrichment were related to adaptive psychological and physical functioning. The present findings underscore the importance of the concept of illness identity. The IIQ, a self-report questionnaire, is introduced to measure four different illness identity states in adults with a chronic illness.

The incidence of pre-eclampsia ranges from 3% to 7% for nulliparas and 1% to 3% for multiparas. Pre-eclampsia is a major cause of maternal mortality and morbidity, preterm birth, perinatal death, and intrauterine growth restriction. Unfortunately, the pathophysiology of this multisystem disorder, characterized by abnormal vascular response to placentation, is still unclear. Despite great polymorphism of the disease, the criteria for pre-eclampsia have not changed over the past decade (systolic blood pressure >140 mmHg or diastolic blood pressure ≥90 mmHg and 24-hour proteinuria ≥0.3 g). Clinical features and laboratory abnormalities define and determine the severity of pre-eclampsia. Delivery is the only curative treatment for pre-eclampsia. Multidisciplinary management, involving an obstetrician, anesthetist, and pediatrician, is carried out with consideration of the maternal risks due to continued pregnancy and the fetal risks associated with induced preterm delivery. Screening women at high risk and preventing recurrences are key issues in the management of pre-eclampsia. PMID:21822394

He also presented with bilateral sensorineural hearing loss, anaemia, hypergammaglobulinaemia, and bone disorders. Histopathology studies of the skin and testicular masses reported lymphoplasmacytic infiltration. Sequencing analysis of gene SLC29A3 showed the homozygote mutation c.1087 C>T (p.Arg363Trp; rs387907067). These findings are consistent with H syndrome, and this is the first reported case in Latin America. The key to the diagnosis is the finding of hyperpigmentation with hypertrichosis.

Behcet's disease (BD) is a chronic, multi-systemic and inflammatory disorder. The local renin-angiotensin system (RAS) in the vessel wall plays a role in the endothelial control and contributes to inflammatory processes. Angiotensin-converting enzyme (ACE) is the regulatory component of the RAS. This study was conducted in Turkish patients with BD to determine the frequency of I/D polymorphism genotypes of ACE gene. Genomic DNA obtained from 566 persons (266 patients with BD and 300 healthy controls). ACE gene I/D polymorphism genotypes were determined using polymerase chain reaction using I and D allele-specific primers. There was statistically significant difference between the groups with respect to genotype distribution (p < 0.001). This study is the largest study in Turkish population that ACE gene I/D polymorphism investigated in BD. As a result of this study, ACE gene I/D polymorphism DD genotype could be a genetic marker in BD in Turkish study population.

Tick-borne infectious diseases in Australia.

Tick bites in Australia can lead to a variety of illnesses in patients. These include infection, allergies, paralysis, autoimmune disease, post-infection fatigue and Australian multisystem disorder. Rickettsial (Rickettsia spp.) infections (Queensland tick typhus, Flinders Island spotted fever and Australian spotted fever) and Q fever (Coxiella burnetii) are the only systemic bacterial infections that are known to be transmitted by tick bites in Australia. Three species of local ticks transmit bacterial infection following a tick bite: the paralysis tick (Ixodes holocyclus) is endemic on the east coast of Australia and causes Queensland tick typhus due to R. australis and Q fever due to C. burnetii; the ornate kangaroo tick (Amblyomma triguttatum) occurs throughout much of northern, central and western Australia and causes Q fever; and the southern reptile tick (Bothriocroton hydrosauri) is found mainly in south-eastern Australia and causes Flinders Island spotted fever due to R. honei. Much about Australian ticks and the medical outcomes following tick bites remains unknown. Further research is required to increase understanding of these areas.

Learning from Job: A Rare Genetic Disease and Lessons of Biblical Proportions

Milner, Joshua D.

2018-01-01

Dominant negative mutations in STAT3, a critical signaling molecule and transcription factor in multiple organ systems, lead to a rare monogenic disease called the STAT3 loss-of-function, autosomal dominant hyper-IgE syndrome (STAT3LOF AD-HIES). The original name for this syndrome, Job’s syndrome, was derived from the observation that patients had a propensity to develop skin boils, reminiscent of the affliction cast upon the biblical Job. Many fascinating observations have been made regarding the pathogenesis of the disease and the role STAT3 plays in human health and disease. Additionally, quite a few phenotypic descriptions from the Book of Job are similar to those seen in patients with STAT3LOF AD-HIES, beyond just the boils. This complex multisystem genetic disorder is a challenge clinically and scientifically, but it also brings into question how we approach genetic syndromes beyond just the technical aspects of research and treatment.

History  A 30-year-old man presented with a history of progressive muscle weakness, difficulty in concentrating, and a slender habitus since early childhood. Marfan syndrome was suspected since the age of 14. Examinations  13 years later he was examined by Marfan experts and by genetic testing and Marfan syndrome could not be confirmed. Further neurological examination revealed the suspected diagnosis of myotonic dystrophy type 1, which was confirmed by genetic testing. Treatment and course  Similar to Marfan syndrome, myotonic dystrophy is a multisystemic disorder with the risk of cardiac arrythmias. It is necessary to provide an interdisciplinary care by neurologists, internists, ophthalmologists, speech therapists, and physiotherapists. Conclusion  It is not enough to take the habitus as the principle sign to diagnose Marfan syndrome. Furthermore, it is essential to consider symptoms that are not typical for Marfan syndrome, such as cognitive deficiencies or progressive paresis. © Georg Thieme Verlag KG Stuttgart · New York.

Borrelia burgdorferi is the causative agent of Lyme disease that persists in a complex enzootic life cycle, involving Ixodes ticks and vertebrate hosts. The microbe invades ticks and vertebrate hosts in spite of active immune surveillance and potent microbicidal responses, and establishes long-term infection utilizing mechanisms that are yet to be unraveled. The pathogen can cause multi-system disorders when transmitted to susceptible mammalian hosts, including in humans. In the past decades, several studies identified a limited number of B. burgdorferi gene-products critical for pathogen persistence, transmission between the vectors and the host, and host-pathogen interactions. This review will focus on the interactions between B. burgdorferi proteins, as well between microbial proteins and host components, protein and non-protein components, highlighting their roles in pathogen persistence in the mammalian host. A better understanding of the contributions of protein interactions in the microbial virulence and persistence of B. burgdorferi would support development of novel therapeutics against the infection.

2012-01-01

Definition of the disease Behçet disease (BD) is a chronic, relapsing, multisystemic disorder characterized by mucocutaneous, ocular, vascular and central nervous system manifestations. Epidemiology BD seems to cluster along the ancient Silk Road, which extends from eastern Asia to the Mediterranean basin. European cases are often described, not exclusively in the migrant population. Clinical description The clinical spectrum includes oral and genital ulcerations, uveitis, vascular, neurological, articular, renal and gastrointestinal manifestations. Etiology The etiopathogenesis of the disease remains unknown, although genetic predisposition, environmental factors and immunological abnormalities have been implicated. Diagnostic methods Diagnosis is only based on clinical criteria. Differrential diagnosis It depends on the clinical presentation of BD, but sarcoidosis, multiple sclerosis, Crohn’s disease, Takayasu’s arteritis, polychondritis or antiphospholipid syndrome need to be considered. Management Treatment is symptomatic using steroids and immunomodulatory therapy. It is efficient depending on the rapidity of initiation, the compliance, and the duration of therapy. Prognosis The prognosis is severe due to the ocular, neurological and arterial involvement. PMID:22497990

Early Renal Involvement in a Girl with Classic Fabry Disease.

PubMed

Perretta, Fernando; Antongiovanni, Norberto; Jaurretche, Sebastián

2017-01-01

Fabry disease is an X-linked lysosomal storage disorder resulting from the deficiency or absence of the enzyme alpha galactosidase A; this defect leads to the systemic accumulation of globotriaosylceramide and its metabolites. Organic involvement in men is well known, but in women it is controversial, mainly due to the random X-chromosome inactivation in each of their cells (Lyon hypothesis). This would explain why women (heterozygotes) present a wide variability in the severity of their phenotype. The manifestations are multisystemic and begin in early childhood, reaching a severe compromise in adulthood. Typical acroparesthesia in hands and feet, gastrointestinal symptoms, angiokeratomas, dyshidrosis, hearing loss, arrhythmias, hypertrophic cardiomyopathy, cerebrovascular accidents, and renal failure can be observed. Nephropathy is one of the major complications of Fabry disease. Glomerular and vascular changes are present before progression to overt proteinuria and decreased glomerular filtration rate, even in pediatric patients. A case of incipient renal involvement in a girl with classic Fabry disease is reported.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a rare multisystemic autosomal recessive disorder mainly caused by mutations in the nuclear gene TYMP, encoding thymidine phosphorylase. It generally appears in childhood and is clinically characterized by severe gastrointestinal dysmotility, cachexia, ptosis, progressive external ophthalmoplegia, peripheral neuropathy, and diffuse leukoencephalopathy on brain magnetic resonance imaging. The disease is clinically heterogeneous with the main symptoms being gastrointestinal, with an important weight loss. Symptoms might worsen rapidly, and a timely diagnosis is vital. However, patients report retrospectively their first symptoms before the age of 12 years, but the delay in diagnosis varies from 5 to 10 years. In the present study, we report a case of an adolescent with MNGIE, which was initially, and erroneously, diagnosed as anorexia nervosa. To make a timely and accurate differential diagnosis, we will discuss the clinical differences and similarities between MNGIE and anorexia nervosa and the importance of a multidisciplinary evaluation.

Vogt-Koyanagi-Harada disease (VKHD) is a multisystemic disorder characterized by granulomatous panuveitis variably combined with T cell-mediated neurologic and cutaneous manifestations. Early and aggressive treatment with systemic corticosteroids is the mainstay of treatment for VKHD. Additional use of immunosuppressants, intravenous immunoglobulins, and tumor necrosis factor-alpha inhibitors can help the most severely affected patients and work as corticosteroid-sparing agents. We report the case of a young woman with relapsing and multiresistant VKHD who demonstrated a stable remission of both uveitis and high-frequency hearing loss following rituximab intravenous administration (1 g. twice, 2 weeks apart, and 6 months later). A complete clinical response was observed 1 month since the first infusion, and no ocular relapses were recorded during the following year; in addition, audiometry showed a high-frequency hearing recovery in the right ear. Further observational studies are required to define the role of CD20 inhibition in the management of VKHD.

Pearson marrow pancreas syndrome (PS) is a multisystem disorder caused by mitochondrial DNA (mtDNA) deletions. Diamond-Blackfan anemia (DBA) is a congenital hypoproliferative anemia in which mutations in ribosomal protein genes and GATA1 have been implicated. Both syndromes share several features including early onset of severe anemia, variable nonhematologic manifestations, sporadic genetic occurrence, and occasional spontaneous hematologic improvement. Because of the overlapping features and relative rarity of PS, we hypothesized that some patients in whom the leading clinical diagnosis is DBA actually have PS. Here, we evaluated patient DNA samples submitted for DBA genetic studies and found that 8 (4.6%) of 173 genetically uncharacterized patients contained large mtDNA deletions. Only 2 (25%) of the patients had been diagnosed with PS on clinical grounds subsequent to sample submission. We conclude that PS can be overlooked, and that mtDNA deletion testing should be performed in the diagnostic evaluation of patients with congenital anemia. © 2014 by The American Society of Hematology.

Systemic sclerosis (SSc), or scleroderma, is a chronic multisystem autoimmune disorder characterised by thickening and fibrosis of the skin and by the involvement of internal organs such as the lungs, kidneys, gastrointestinal tract, and heart. Because there is no cure, feasibly-implemented and easily accessible evidence-based interventions to improve health-related quality of life (HRQoL) are needed. Due to a lack of evidence, however, specific recommendations have not been made regarding non-pharmacological interventions (e.g. behavioural/psychological, educational, physical/occupational therapy) to improve HRQoL in SSc. The Scleroderma Patient-centred Intervention Network (SPIN) was recently organised to address this gap. SPIN is comprised of patient representatives, clinicians, and researchers from Canada, the USA, and Europe. The goal of SPIN, as described in this article, is to develop, test, and disseminate a set of accessible interventions designed to complement standard care in order to improve HRQoL outcomes in SSc.

Williams–Beuren syndrome (WBS) is a rare multisystem disorder caused by a hemizygous deletion of the elastin gene on chromosome 7q11.23. WBS patients have characteristic skeletal features and dental anomalies accompanied by mental retardation, a friendly outgoing personality, and mild to moderate intellectual disability or learning problems. In this case report, we present the combined orthodontic and surgical treatment of a WBS patient with an isolated cleft palate through a long-term follow-up from the age of 5 to 24 years. During the period of active treatment, comprehensive orthodontic treatment combined with maxillary anterior segmental distraction osteogenesis and prosthetic treatment using dental implants were effective in dramatically improving the patient's malocclusion. The patient's mental abilities and the cooperation shown by the patient and her family were crucial for the success of this complex and long-term treatment course. PMID:28744380

Cardiac considerations in the operative management of the patient with Duchenne or Becker muscular dystrophy.

PubMed

Cripe, Linda H; Tobias, Joseph D

2013-09-01

Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) is a progressive multisystem neuromuscular disorder. In addition to the skeletal muscle, the myocardium in the DMD/BMD patient is dystrophin deficient which results in a progressive cardiomyopathy. The myopathic myocardium poses significant risk of increased morbidity and mortality at the time of major surgical procedures. Careful attention must be given to the DMD/BMD patient during the intraoperative and postoperative period. Anesthesia selection is critical and anesthetics should be avoided which have been shown to be harmful in this patient population. Preanesthesia assessment should include cardiac consultation and detailed preoperative evaluation. Intraoperative management needs to insure that the weakened myocardium is not compromised by physiologic changes such as hypotension or major fluid shifts. Finally, attention to the cardiac status of the patient must continue into the postoperative period. The surgical care of the DMD/BMD patient requires a multispecialty approach to insure operative success. © 2013 John Wiley & Sons Ltd.

A universal array-based multiplexed test for cystic fibrosis carrier screening.

Amos, Jean A; Bridge-Cook, Philippa; Ponek, Victor; Jarvis, Michael R

2006-01-01

Cystic fibrosis is a multisystem autosomal recessive disorder with high carrier frequencies in caucasians and significant, but lower, carrier frequencies in other ethnicities. Based on technology that allows high detection of mutations in caucasians and significant detection in other ethnic groups, the American College of Medical Genetics (ACMG) and American College of Obstetricians and Gynecologists (ACOG) have recommended pan-ethnic cystic fibrosis carrier screening for all reproductive couples. This paper discusses carrier screening using the Tag-It multiplex mutation platform and the Cystic Fibrosis Mutation Detection Kit. The Tag-It cystic fibrosis assay is a multiplexed genotyping assay that detects a panel of 40 cystic fibrosis transmembrane conductance regulator mutations including the 23 mutations recommended by the ACMG and ACOG for population screening. A total of 16 additional mutations detected by the Tag-It cystic fibrosis assay may also be common. The assay method is described in detail, and its performance in a genetics reference laboratory performing high-volume cystic fibrosis carrier screening is assessed.

Neurosarcoidosis associated with intracerebral haemorrhage: a challenge in diagnosis and management.

PubMed

Maskery, Mark Peter; Cooper, Paul N; Pace, Adrian

2018-06-01

Sarcoidosis is an idiopathic multisystem granulomatous disorder of unknown cause. Nervous system involvement (central and/or peripheral) is uncommon, developing in 5%-10%. The presenting symptoms are variable, reflecting the level of involvement, and frequently fluctuate and progress. Diagnosing neurosarcoidosis in people with previously confirmed systemic disease may be relatively straightforward, but diagnosing primary neurosarcoidosis is challenging. Managing neurosarcoidosis is primarily consensus based; corticosteroid is its mainstay, alongside corticosteroid-sparing agents and emerging novel therapies. We describe a 39-year-old woman who presented with cranial neuropathy. Serial imaging, cerebrospinal fluid sampling and tissue biopsy gave a diagnosis of probable neurosarcoidosis. Her clinical course was complicated by intracerebral haemorrhage following intravenous corticosteroids for neurological relapse. This is a very rare complication of neurosarcoidosis; we discuss its possible causes and suggest ways to reduce its risk. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Chronic inflammation triggered by the NLRP3 inflammasome in myeloid cells promotes growth plate dysplasia by mesenchymal cells.

Skeletal complications are common features of neonatal-onset multisystem inflammatory disease (NOMID), a disorder caused by NLRP3-activating mutations. NOMID mice in which NLRP3 is activated globally exhibit several characteristics of the human disease, including systemic inflammation and cartilage dysplasia, but the mechanisms of skeletal manifestations remain unknown. In this study, we find that activation of NLRP3 in myeloid cells, but not mesenchymal cells triggers chronic inflammation, which ultimately, causes growth plate and epiphyseal dysplasia in mice. These responses are IL-1 signaling-dependent, but independent of PARP1, which also functions downstream of NLRP3 and regulates skeletal homeostasis. Mechanistically, inflammation causes severe anemia and hypoxia in the bone environment, yet down-regulates the HIF-1α pathway in chondrocytes, thereby promoting the demise of these cells. Thus, activation of NLRP3 in hematopoietic cells initiates IL-1β-driven paracrine cascades, which promote abnormal growth plate development in NOMID mice.

Opioid use disorder is a highly disabling psychiatric disorder, and is associated with both significant functional disruption and risk for negative health outcomes such as infectious disease and fatal overdose. Even among those who receive evidence-based pharmacotherapy for opioid use disorder, many drop out of treatment or relapse, highlighting the importance of novel treatment strategies for this population. Over 60% of those with opioid use disorder also meet diagnostic criteria for an anxiety disorder; however, efficacious treatments for this common co-occurrence have not be established. This manuscript describes the rationale and methods for a behavioral treatment development study designed to develop and test an integrated cognitive-behavioral therapy for those with co-occurring opioid use disorder and anxiety disorders. The aims of the study are (1) to develop and pilot test a new manualized cognitive behavioral therapy for co-occurring opioid use disorder and anxiety disorders, (2) to test the efficacy of this treatment relative to an active comparison treatment that targets opioid use disorder alone, and (3) to investigate the role of stress reactivity in both prognosis and recovery from opioid use disorder and anxiety disorders. Our overarching aim is to investigate whether this new treatment improves both anxiety and opioid use disorder outcomes relative to standard treatment. Identifying optimal treatment strategies for this population are needed to improve outcomes among those with this highly disabling and life-threatening disorder. Copyright © 2017 Elsevier Inc.

Myotonic dystrophy type 1 (DM1), the most common muscular dystrophy observed in adults, is a genetic multisystem disorder affecting several other organs besides skeletal muscle, including the brain. Cognitive and personality abnormalities have been reported; however, no studies have investigated brain functional networks and their relationship with personality traits/disorders in patients with DM1. To use resting-state functional magnetic resonance imaging to assess the potential relationship between personality traits/disorders and changes to functional connectivity within the default mode network (DMN) in patients with DM1. We enrolled 27 patients with genetically confirmed DM1 and 16 matched healthy control individuals. Patients underwent personality assessment using clinical interview and Minnesota Multiphasic Personality Inventory-2 administration; all participants underwent resting-state functional magnetic resonance imaging. Investigations were conducted at the Istituto di Ricovero e Cura a Carattere Scientifico Santa Lucia Foundation, Catholic University of Sacred Heart, and Azienda Ospedaliera San Camillo Forlanini. Resting-state functional magnetic resonance imaging. Measures of personality traits in patients and changes in functional connectivity within the DMN in patients and controls. Changes in functional connectivity and atypical personality traits in patients were correlated. We combined results obtained from the Minnesota Multiphasic Personality Inventory-2 and clinical interview to identify a continuum of atypical personality profiles ranging from schizotypal personality traits to paranoid personality disorder within our DM1 patients. We also demonstrated an increase in functional connectivity in the bilateral posterior cingulate and left parietal DMN nodes in DM1 patients compared with controls. Moreover, patients with DM1 showed strong associations between DMN functional connectivity and schizotypal-paranoid traits. Our findings provide novel biological evidence that DM1 is a clinical condition that also involves an alteration of functional connectivity of the brain. We speculate that these functional brain abnormalities, similarly to frank psychiatric disorders, may account for the atypical personality traits observed in patients with DM1.

Dermal fibroblast-to-myofibroblast transition sustained by αvß3 integrin-ILK-Snail1/Slug signaling is a common feature for hypermobile Ehlers-Danlos syndrome and hypermobility spectrum disorders.

2018-04-01

Hypermobile Ehlers-Danlos syndrome (hEDS) is a heritable connective tissue disorder with unknown molecular basis mainly characterized by generalized joint hypermobility, joint instability complications, and minor skin changes. The phenotypic spectrum is broad and includes multiple associated symptoms shared with chronic inflammatory systemic diseases. The stricter criteria defined in the 2017 EDS nosology leave without an identity many individuals with symptomatic joint hypermobility and/or features of hEDS; for these patients, the term Hypermobility Spectrum Disorders (HSD) was introduced. We previously reported that in vitro cultured hEDS and HSD patients' skin fibroblasts show a disarray of several extracellular matrix (ECM) components and dysregulated expression of genes involved in connective tissue homeostasis and inflammatory/pain/immune responses. Herein, we report that hEDS and HSD skin fibroblasts exhibit in vitro a similar myofibroblast-like phenotype characterized by the organization of α-smooth muscle actin cytoskeleton, expression of OB-cadherin/cadherin-11, enhanced migratory capability associated with augmented levels of the ECM-degrading metalloproteinase-9, and altered expression of the inflammation mediators CCN1/CYR61 and CCN2/CTGF. We demonstrate that in hEDS and HSD cells this fibroblast-to-myofibroblast transition is triggered by a signal transduction pathway that involves αvβ3 integrin-ILK complexes, organized in focal adhesions, and the Snail1/Slug transcription factor, thus providing insights into the molecular mechanisms related to the pathophysiology of these protean disorders. The indistinguishable phenotype identified in hEDS and HSD cells resembles an inflammatory-like condition, which correlates well with the systemic phenotype of patients, and suggests that these multisystemic disorders might be part of a phenotypic continuum rather than representing distinct clinical entities.

Neurofibromatosis type 1 (NF1), also known as Von Recklinghausen disease, is one of the most frequent human genetic diseases, with a prevalence of one case in 3000 births, an autosomal dominant mode of inheritance, and a high rate of new mutations. NF1 has markedly variable clinical expression, with manifestations ranging from mild lesions to several complications and functional impairment. The complications are age-specific. Psychiatric disorders are more frequent in NF1 than in the general population, especially in children. They include dysthymia, depressive mood, anxiety, and personality disorders. Bipolar mood disorders or schizophrenia are rather rare. The majority of studies have focused on physical health and neurocognitive function in NF1, whereas psychiatric disorders associated with this disease remain unclear and poorly documented. This report is based on a clinical case and discusses the relationship between neurofibromatosis type 1 and psychiatric disorders, particularly anxiety disorders. This case concerns a 13-year-old girl, the first child of healthy and non-consanguineous parents. The patient's history showed normal psychomotor and psychoaffective development. Her father and paternal grandmother had isolated café-au-lait spots. In June 2013, a subcutaneous mass appeared in her right thigh. She consulted a neurologist and was explored. The physical examination revealed signs of NF1. She had café-au-lait spots on the trunk and extremities, and a neurofibroma in the right thigh. Bilateral ophthalmic examination revealed multiple Lish nodules. After 1 month, a psychiatric consultation was requested for sad mood and night terrors. Obsessive compulsive disorder and generalized anxiety disorder were diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. The current psychiatric literature does not provide full explanations of anxiety symptoms associated with NF1. Some authors have tried to explain the link between NF1 and psychiatric disorders, and several etiopathogenic hypotheses have been discussed. In our case, a concomitant diagnosis of NF1 and anxiety disorders was made at the age of 13. However, anxiety symptoms started to appear before age 4; they increased gradually and occupied the foreground. This would strengthen the hypothesis of genetic determinism in NF1 patients. The question that arises is: is it a fortuitous association of psychiatric disorders and NF1 or are they psychiatric manifestations induced by a multisystem disease? More detailed investigations are necessary to clarify the etiopathogenic and psychopathological mechanisms that would cause psychiatric comorbidity associated with NF1.

Emergency department (ED) care for acute vascular diseases faces the challenge of overcrowding. A vascular unit is a specialized, protocol-oriented unit in the ED with a team trained to manage acute vascular disorders, including stroke, coronary syndromes, pulmonary embolism (PE), and aortic diseases. The objective was to compare case fatality rates for selected cardiovascular conditions before and after the implementation of a vascular unit. Patients with the selected diagnoses admitted to the ED in two different time periods, 2002 through 2005 (before unit opening) and 2007 to 2010 (after vascular unit opening), were identified by ICD-10 codes, and their electronic records were reviewed. Case fatality rates were calculated and compared for both time periods. The period prior to unit implementation (2002 through 2005) included 4,164 patients, and the vascular unit period (2007 to 2010) included 6,280 patients. Overall, the case fatality rate for acute vascular conditions decreased from 9% to 7.3% with vascular unit implementation (p = 0.002). The in-hospital mortality rates for acute coronary syndrome (ACS) dropped from 6% to 3.8% (p = 0.003), and for acute PE dropped from 32.1% to 10.8% (p < 0.001). The stroke case-fatality rate did not decrease despite improvements in the quality of stroke health care indicators. The vascular unit strategy has the potential to reduce overall mortality for most acute vascular conditions. © 2013 by the Society for Academic Emergency Medicine.

A recent English study demonstrated high rates of kitchen knife use in homicides by mentally disordered offenders subject to independent inquiries. Everyone accused of homicide in Scotland undergoes psychiatric examination; all such evaluations in a Scottish region between 2006 and 2011 were systematically analysed to identify homicide characteristics. It was hypothesised that kitchen knives would be the commonest sharp instruments used, and would be associated with unplanned domestic homicide against known victims, with no independent association with mental disorder. Kitchen knives were used in 32 of 55 homicides: 94% of 34 sharp object homicides (p < 0.05). No independent association was found between kitchen knife use and planning, location, relationship, intoxication or mental disorder. Kitchen knife use in homicide appears to be a significant public health issue, and not only in the mentally disordered population. Research is recommended into kitchen knife use in non-fatal violence, and weapon control in populations at increased risk of knife violence.

Toxic oil syndrome is an epidemic, multisystemic disease that appeared in Spain in 1981, and was caused by the consumption of rapeseed oil denatured with 2% aniline. The disease is similar to eosinophilia-myalgia syndrome. One of the cardiovascular disorders caused by this syndrome is pulmonary hypertension. We conducted a study to assess the validity of our indications for echocardiography in the follow-up of cardiovascular disorders in patients with this disease. These patients are followed at our center with a standardized protocol for annual check-ups. From December 1997 through July 2002, a total of 1993 patients were examined. In this period we performed a total of 487 echocardiographic studies in 424 patients. The clinical records were reviewed to assess the indications for echocardiography according to the most recent guidelines for the clinical application of echocardiography of the American College of Cardiology and American Heart Association, and the indications were grouped into several categories. The diagnosis was recorded from the cardiologist's reports at the hospital where echocardiography was done. We calculated the sensitivity, specificity and positive likelihood ratio. 67% of the echocardiographic examinations were indicated to investigate possible pulmonary hypertension. About one-tenth of the studies (476 studies, 9.9%) led to a diagnosis of pulmonary hypertension. Sensitivity was highest (83%) for suspected pulmonary hypertension. Specificity was very high for most of the other indications. This study does not allow us to draw general conclusions about the cardiovascular disorders associated with toxic oil syndrome. However, echocardiography appears to be a good follow-up technique to diagnose complications such as pulmonary hypertension in these patients.

Pre-eclampsia, a pregnancy-specific multisystemic disorder is a leading cause of maternal and perinatal mortality and morbidity. This syndrome has been known to medical science since ancient times. However, despite considerable research, the cause/s of preeclampsia remain unclear, and there is no effective treatment. Development of an animal model that recapitulates this complex pregnancy-related disorder may help to expand our understanding and may hold great potential for the design and implementation of effective treatment. Here we show that the CBA/J x DBA/2 mouse model of recurrent miscarriage is also a model of immunologically-mediated preeclampsia (PE). DBA/J mated CBA/J females spontaneously develop many features of human PE (primigravidity, albuminuria, endotheliosis, increased sensitivity to angiotensin II and increased plasma leptin levels) that correlates with bad pregnancy outcomes. We previously reported that antagonism of vascular endothelial growth factor (VEGF) signaling by soluble VEGF receptor 1 (sFlt-1) is involved in placental and fetal injury in CBA/J x DBA/2 mice. Using this animal model that recapitulates many of the features of preeclampsia in women, we found that pravastatin restores angiogenic balance, ameliorates glomerular injury, diminishes hypersensitivity to angiotensin II and protects pregnancies. We described a new mouse model of PE, were the relevant key features of human preeclampsia develop spontaneously. The CBA/J x DBA/2 model, that recapitulates this complex disorder, helped us identify pravastatin as a candidate therapy to prevent preeclampsia and its related complications. We recognize that these studies were conducted in mice and that clinical trials are needed to confirm its application to humans.

Martin--Probst syndrome (MPS) is a rare X-linked disorder characterised by deafness, cognitive impairment, short stature and distinct craniofacial dysmorphisms, among other features. The authors sought to identify the causative mutation for MPS. Massively parallel sequencing in two affected, related male subjects with MPS identified a RAB40AL (also called RLGP) missense mutation (chrX:102,079,078-102,079,079AC→GA p.D59G; hg18). RAB40AL encodes a small Ras-like GTPase protein with one suppressor of cytokine signalling box. The p.D59G variant is located in a highly conserved region of the GTPase domain between β-2 and β-3 strands. Using RT-PCR, the authors show that RAB40AL is expressed in human fetal and adult brain and kidney, and adult lung, heart, liver and skeletal muscle. RAB40AL appears to be a primate innovation, with no orthologues found in mouse, Xenopus or zebrafish. Western analysis and fluorescence microscopy of GFP-tagged RAB40AL constructs from transiently transfected COS7 cells show that the D59G missense change renders RAB40AL unstable and disrupts its cytoplasmic localisation. This is the first study to show that mutation of RAB40AL is associated with a human disorder. Identification of RAB40AL as the gene mutated in MPS allows for further investigations into the molecular mechanism(s) of RAB40AL and its roles in diverse processes such as cognition, hearing and skeletal development.

Vascular calcification (VC) is one of the factors associated with cardiovascular mortality in hemodialysis (HD) patients. Recommendations concerning screening for VC differ. Possible ability to prevent and reversibility of VC are major subjects on debate whether screening for VC could improve outcomes of renal patients. The objective of the study was to evaluate the significance of simple vascular calcification score (SVCS) based on plane radiographic films and to test its association with non-fatal cardiovascular events in patients on chronic HD. A study population consisted of 95 prevalent HD patients in the HD unit of Hospital of Lithuanian University of Health sciences Kaunas Clinics. Clinical data and laboratory tests information were collected from medical records. SVCS was evaluated as it is described by Adragao et al. After measurement of VC, HD patients were observed for novel non-fatal cardiovascular events. Patients were divided into two groups: SVCS≥3 (57 patients [60%]) and <3 (38 patients [40%]). The Kaplan-Meier survival curves show a significant difference in non-fatal cardiovascular events in the group with SVCS≥3 vs. <3 group (26.3% vs. 7.8%; log rank 5,49; P=0.018). Multivariate Cox regression analysis confirmed a negative impact of VC, hyperphosphatemia, and lower ejection fraction on cardiovascular events. No statistically significant differences were observed comparing parameters of Ca-P metabolism disorders between groups with different SVCS. On separate analysis, the presence of VC in hands was also associated with higher rate of novel cardiovascular events (score 0 goup-5 events [10.6%] vs. score≥1 group-13 events [27%], log rank P=0.035). VC assessed by simple and inexpensive radiological method was an independent predictor of novel non-fatal cardiovascular events in HD patients. Copyright © 2016 Association Société de néphrologie.

Suicide attempts (SAs) in the paediatric age group represent an important cause of morbidity and mortality. Our aim was to examine the factors affecting the decision to hospitalize children with a diagnosis of non-fatal SA by pills. Children <18 years of age admitted with SA by pills during 2014 were evaluated retrospectively. Patients were divided into two groups: Group-I comprised hospitalised patients and Group-II included those who were discharged from the PED. These two groups were compared in terms of clinical and demographic characteristics recorded upon PED admission. A total of 196 patients were included in the study. The number of pills taken for self-poisoning in Group-I (median: 20 pills) was higher than that in Group-II (median: 12 pills) (p < 0.001), and the rate of pathological findings during the first paediatric psychiatric consultation was higher in Group-I (91.1%) than in the Group-II (54.8%) (p < 0.001). Factors affecting the disposition decision in cases of children who performed non-fatal SA via pills included the amount of medication taken for the suicide attempt and the presence of psychiatric disorders, as determined by a paediatric psychiatrist during the acute phase.

Campylobacter jejuni (C. jejuni) bacteremia is difficult to diagnose in individuals with hematological disorders undergoing chemotherapy. The cause can be attributed to the rarity of this infection, to the variable clinical presentation, and to the partial overlapping symptoms underlying the disease. Here, we report a case of a fatal sepsis caused by C. jejuni in a 76-year-old Caucasian man with non-Hodgkin’s lymphoma. After chemotherapeutic treatment, the patient experienced fever associated with severe neutropenia and thrombocytopenia without hemodynamic instability, abdominal pain, and diarrhea. The slow growth of C. jejuni in the blood culture systems and the difficulty in identifying it with conventional biochemical phenotyping methods contributed to the delay of administering a targeted antimicrobial treatment, leading to a fatal outcome. Early recognition and timely intervention are critical for the successful management of C. jejuni infection. Symptoms may be difficult to recognize in immunocompromised patients undergoing chemotherapy. Thus, it is important to increase physician awareness regarding the clinical manifestations of C. jejuni to improve therapeutic efficacy. Moreover, the use of more aggressive empirical antimicrobial treatments with aminoglycosides and/or carbapenems should be considered in immunosuppressed patients, in comparison to those currently indicated in the guidelines for cancer-related infections supporting the use of cephalosporins as monotherapy.

This study evaluated the effectiveness of a multisystemic early intervention that included a comparison of an emotion- and behavior-focused parenting program for children with emerging conduct problems. The processes that moderated positive child outcomes were also explored. A repeated measures cluster randomized group design methodology was employed with three conditions (Tuning in to Kids, Positive Parenting Program, and waitlist control) and two periods (preintervention and 6-month follow-up). The sample consisted of 320 predominantly Caucasian 4- to 9-year-old children who were screened for disruptive behavior problems. Three outcome measures of child conduct problems were evaluated using a parent (Eyberg Child Behavior Inventory) and teacher (Strengths and Difficulties Questionnaire) rating scale and a structured child interview (Home Interview With Child). Six moderators were assessed using family demographic information and a parent-rated measure of psychological well-being (Depression Anxiety and Stress Scales short form). The results indicated that the multisystemic intervention was effective compared to a control group and that, despite different theoretical orientations, the emotion- and behavior-focused parenting programs were equally effective in reducing child conduct problems. Child age and parent psychological well-being moderated intervention response. This effectiveness trial supports the use of either emotion- or behavior-focused parenting programs in a multisystemic early intervention and provides greater choice for practitioners in the selection of specific programs.

Health consequences of sexual violence against women.

Sexual violence can lead to a multitude of health consequences, including physical, reproductive and psychological. Some may be fatal, whereas others, such as unhealthy behaviours, may occur indirectly as a result of the violence. In total, these result in a significant health burden and should be considered by service providers, government authorities and non-governmental agencies. For women who present early, immediate care should be provided with plans for follow up. Mental-health interventions are important, as women who are sexually assaulted have the highest burden of post-traumatic stress disorder. Cognitive- behavioural therapy has been found to be effective for preventing and treating post-traumatic stress disorder, but psychological debriefing for preventing post-traumatic stress disorder is not recommended. Implementing a routine screening and intervention programme in obstetrics and gynaecology departments may be valuable, as reproductive health consequences are common. Copyright © 2012 Elsevier Ltd.

The existence of acquired cholesteatoma has been recognized for more than three centuries; however, the nature of the disorder has yet to be determined. Without timely detection and intervention, cholesteatomas can become dangerously large and invade intratemporal structures, resulting in numerous intra- and extracranial complications. Due to its aggressive growth, invasive nature, and the potentially fatal consequences of intracranial complications, acquired cholesteatoma remains a cause of morbidity and death for those who lack access to advanced medical care. Currently, no viable nonsurgical therapies are available. Developing an effective management strategy for this disorder will require a comprehensive understanding of past progress and recent advances. This paper presents a brief review of background issues related to acquired middle ear cholesteatoma and deals with practical considerations regarding the history and etymology of the disorder. We also consider issues related to the classification, epidemiology, histopathology, clinical presentation, and complications of acquired cholesteatoma and examine current diagnosis and management strategies in detail.

Background Zika virus (ZIKV) was first detected in Brazil in May 2015 and the country experienced an explosive epidemic. However, recent studies indicate that the introduction of ZIKV occurred in late 2013. Cases of microcephaly and deaths associated with ZIKV infection were identified in Brazil in November, 2015. Objectives To determine the etiology of three fatal adult cases. Study design Here we report three fatal adult cases of ZIKV disease. ZIKV infection in these patients was confirmed by cells culture and/or real-time reverse transcriptase polymerase chain reaction (RT-qPCR) and by antigen detection using immunohistochemical assay. Samples of brain and other selected organs taken at autopsy from three patients were also analyzed by histopathological and immunohistological examination. Results The first patient, a 36-year-old man with lupus and receiving prednisone therapy, developed a fulminant ZIKV infection. At autopsy, RT-qPCR of blood and tissues was positive for ZIKV RNA, and the virus was cultured from an organ homogenate. The second patient, a previously healthy female, 16 years of age, presented classic symptoms of Zika fever, but later developed severe thrombocytopenia, anemia and hemorrhagic manifestations and died. A blood sample taken on the seventh day of her illness was positive RT-PCR for ZIKV RNA and research in the serum was positive for antinuclear factor fine speckled (1/640), suggesting Evans syndrome (hemolytic anemia an autoimmune disorder with immune thrombocytopenic purpura) secondary to ZIKV infection. The third patient was a 20-year-old woman hospitalized with fever, pneumonia and hemorrhages, who died on 13 days after admission. Histopathological changes were observed in all viscera examined. ZIKV antigens were detected by immunohistochemistry in viscera specimens of patients 1 and 3. These three cases demonstrate other potential complications of ZIKV infection, in addition to microcephaly and Guillain-Barre syndrome (GBS), and they suggest that individuals with immune suppression and/or autoimmune disorders may be at higher risk of developing severe disease, if infected with ZIKV.

We examined multi-system influences on risky sexual behavior measured by cumulative sexual risk index and number of nonromantic sexual partners among 4,465 single, sexually experienced adolescents. Hierarchical Poisson regression analyses were conducted with Wave I-II data from the National Longitudinal Study of Adolescent Health. Individual and family factors predicted both outcome measures. Neighborhood set predicted cumulative sexual risk index only, and peer factors predicted the number of nonromantic sexual partners only. School set did not predict either outcome. There were significant associations among risky sexual behavior, drug use, and delinquent behaviors. The results highlight the need for multifaceted prevention programs that address relevant factors related to family, peer and neighborhood influence as well as individual factors among sexually active adolescents.

Granulomatosis with polyangiitis (GPA, formerly Wegener’s granulomatosis) is a multisystem autoimmune condition associated with anti-neutrophil cytoplasm antibodies. Management of GPA can be complex, owing to the sometimes fulminant and multisystem nature of the presentation, the age demographics of the affected population, and a significant incidence of disease relapse. In this paper, we discuss how some of the challenges in the management of GPA have been and continue to be addressed including: reducing the toxicity of induction therapy; developing biomarkers to determine who can safely stop maintenance immunosuppression; improving the efficacy of maintenance therapy for relapsing patients; managing localized disease; and management of disease and treatment-associated comorbidity. Consideration is also given to emerging therapeutics in the treatment of GPA. PMID:24790453

More knowledge about suicidality and suicide risk profiles in acute psychiatric hospital patients (both first-time and chronic patients) is needed. While numerous factors are associated with suicidality in such populations, these may differ across cultures. Better understanding of factors underlying suicide risk can be informed by cross-cultural studies, and can aid development of therapeutic and preventive measures. An explorative, cross-sectional cohort study was carried out. Acutely admitted patients at one psychiatric hospital in northwest Russia and two in northern Norway were included. At admission, demographic, clinical, and service use data were collected, in addition to an assessment of suicidal ideation and attempts, comprising five dichotomic questions. Data from 358 Norwegian and 465 Russian patients were analyzed with univariate and multivariate statistics. Within each cohort, attempters and ideators were compared with patients not reporting any suicidality. The observed prevalence of suicidal ideation and attempts was significantly higher in the Norwegian cohort than in the Russian cohort (χ(2) = 168.1, p < 0,001). Norwegian suicidal ideators and attempters had more depressed moods, more personality disorders, and greater problems with alcohol/drugs, but fewer psychotic disorders, cognitive problems or overactivity than non-suicidal patients. Russian suicidal ideators and attempters were younger, more often unemployed, had more depressed mood and adjustment disorders, but had fewer psychotic disorders and less alcohol/drug use than the non-suicidal patients. Rates of suicidal ideation and non-fatal attempts in Norwegian patients were intermediate between those previously reported for patients admitted for the first time and those typical of chronic patients. However, the significantly lower rates of suicidal ideation and non-fatal attempts in our Russian cohort as compared with the Norwegian, contrasted with what might be expected in a region with much higher suicide rates than in northern Norway. We suggest that suicide-related stigma in Russia may reduce both patient reporting and clinicians' recognition of suicidality. In both cohorts, overlapping risk profiles of ideators and attempters may indicate that ideators should be carefully evaluated and monitored, particularly those with depressed moods, alcohol/substance abuse disorders, and inadequate treatment continuity.

A parent who continuously physically abuses her/his child doesn't aim to kill the child but commits an accidental filicide in a more violent outburst of anger. Fatal abuse deaths are prevented by recognition of signs of battering in time. Out of 200 examined intra-familial filicides, 23 (12%) were caused by child battering and 13 (7%) by continuous battering. The medical and court records of the victim and the perpetrator were examined. The perpetrator was the biological mother and the victim was male in 69 per cent of the cases. The abused children were either younger than one year or from two-and-a-half to four years old. Risk factors of the victim (being unwanted, premature birth, separation from the parent caused by hospitalization or custodial care, being ill and crying a lot) and the perpetrator (personality disorder, low socioeconomic status, chaotic family conditions, domestic violence, isolation, alcohol abuse) were common. The injuries caused by previous battering were mostly soft tissue injuries in head and limbs and head traumas and the battering lasted for days or even an year. The final assault was more violent and occurred when the parent was more anxious, frustrated or left alone with the child. The perpetrating parent was diagnosed as having a personality disorder (borderline, narcissistic or dependent) and often substance dependence (31%). None of them were psychotic. Authorities and community members should pay attention to the change in child's behavior and inexplicable injuries or absence from daycare. Furthermore if the parent is immature, alcohol dependent, have a personality disorder and is unable to cope with the demands the small child entails in the parent's life, the child may be in danger.

Gorlin-Goltz syndrome is a rare genetic condition showing a variable expressiveness. It is inherited in a dominant autosomal way. The strongest characteristic of the disease includes multiple basal cell carcinomas, jaw cysts, palmar and plantar pits, skeletal abnormalities and other developmental defects. Owing to the fact that the condition tends to be a multisystemic disorder, familiarity of various medical specialists with its manifestations may reduce the time necessary for providing a diagnosis. It will also enable them to apply adequate methods of treatment and secondary prevention. In this study, we present symptoms of the disease, its diagnostic methods and currently used treatments. We searched 2 scientific databases: Medline (EBSCO) and Science Direct, for the years 1996 to 2011. In our search of abstracts, key words included nevoid basal cell carcinoma syndrome and Gorlin-Goltz syndrome. We examined 287 studies from Medline and 80 from Science Direct, all published in English. Finally, we decided to use 60 papers, including clinical cases and literature reviews. Patients with Gorlin-Goltz syndrome need particular multidisciplinary medical care. Knowledge of multiple and difficult to diagnose symptoms of the syndrome among professionals of various medical specialties is crucial. The consequences of the disease pose a threat to the health and life of patients. Therefore, an early diagnosis creates an opportunity for effective prevention and treatment of the disorder. Prevention is better than cure.

Tuberous sclerosis complex (TSC) is an autosomal dominant and multi-system genetic disorder in humans. TSC affects around 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. TSC occurs in all races and ethnic groups, and in both genders. TSC is caused by defects or mutations in two genes, TSC1 and TSC2. Loss of TSC1/TSC2 leads to dysregulation of mTOR, resulting in aberrant cell differentiation and development, and abnormal enlargement of cells. TSC is characterized by the development of benign and/or malignant tumors in several organs including renal/liver angiomyolipomas, facial angiofibroma, lymphangiomyomatosis, cardiac rhabdomyomas, retinal astrocytic, renal cell carcinoma, and brain subependymal giant cell astrocytomas (SEGA). In addition, TSC disease causes disabling neurologic disorders, including epilepsy, mental retardation and autism. Particularly problematic are the development of renal angiomyolipomas, which tend to be larger, bilateral, multifocal and present at a younger age compared with sporadic forms. In addition, SEGA block the flow of fluid within the brain, causing a buildup of fluid and pressure that leads to blurred vision and seizures. In the current review, we describe the pathology of TSC disease in key organs and summarize the use of mTOR inhibitors to treat tumors in TSC patients.

Behçet's Syndrome (BS) is a chronic recurrent multisystemic inflammatory disorder characterized by oral and genital ulcers, ocular inflammation. Behçet's syndrome has a complex genetic etiology. However, epidemiological studies recommend that genetic factors have a significant influence to its pathogenesis, alike to other autoinflammatory disorders. Epidemiological statistics, clinical records and HLA typing were studied in Iranian Azari patients with Behçet's syndrome. This investigation considered HLA associations with BS and HLA with certain clinical characteristics, age and sex in the (Tabriz) Iran which has an ethnically homogeneous population. HLA-A and HLA-B typing was performed in 290 BS patients, conforming to International Study Group criteria and in 300 blood donors, as controls. Patient records were retrospectively reviewed and patients reassessed clinically. HLA-B5, HLA-B35, HLA-51, HLA-B52 and HLA-CW4 presented significantly high frequencies in all patients. No other HLA type was associated. There was a significant HLA link with male sex in BS patients and Mean age (34 +/- 1.1) was determined. We present the frequency and correlation between Iranian Azari patients with Behçet's syndrome and particular HLA antigens. Ninety nine percent had mouth ulceration, 64% genital ulceration, 72% skin lesions and 52% ocular involvement. This study supports HLA-B5, HLA-B35, HLA-51, HLA-B52 and HLA-CW4 immunogenetic predisposition in an ethnically homogeneous (Iranian Azari) population.

Neurofibromatosis von Recklinghausen type 1 (NF1) is an autosomal dominant neurocutaneous disorder affecting one in 3 000-4 000 individuals. Mid-aortic syndrome (MAS) is a rare condition characterized by segmental narrowing of abdominal aorta and stenosis of its major branches - mainly renal arteries, including manifestation of renovascular hypertension. MAS can be caused by different diseases, including NF1. A 9 years old girl with primary diagnosis of NF1 combined with renovascular hypertension due to MAS, suffered of bilateral optic and chiasm glioma, pubertas praecox, speech disorder, light mental retardation and scoliosis. We have found a mutation in exone 34 of the NF1 gene (17q11.2). Her father has been also diagnosed with NF1 and hypertension developed at early age. He has the same mutation in exone 34 of NF1 gene. The girl is currently treated with conservative antihypertensive medication with positive effect. Bilateral optic and chiasm glioma are asymptomatic at the time and they had been without progress over period of time. Any vascular surgery, neurosurgical and oncological therapy are not indicated at the present time. This article is a summary of clinical findings in patient with NF1 due to NF1 gene mutation in exone 34. It confirms the importance of complex multidisciplinar approach to examination and taking care of NF1 patients and their families.

Tuberous sclerosis complex (TSC) is an autosomal dominant and multi-system genetic disorder in humans. TSC affects around 25,000 to 40,000 individuals in the United States and about 1 to 2 million individuals worldwide, with an estimated prevalence of one in 6,000 newborns. TSC occurs in all races and ethnic groups, and in both genders. TSC is caused by defects or mutations in two genes, TSC1 and TSC2. Loss of TSC1/TSC2 leads to dysregulation of mTOR, resulting in aberrant cell differentiation and development, and abnormal enlargement of cells. TSC is characterized by the development of benign and/or malignant tumors in several organs including renal/liver angiomyolipomas, facial angiofibroma, lymphangiomyomatosis, cardiac rhabdomyomas, retinal astrocytic, renal cell carcinoma, and brain subependymal giant cell astrocytomas (SEGA). In addition, TSC disease causes disabling neurologic disorders, including epilepsy, mental retardation and autism. Particularly problematic are the development of renal angiomyolipomas, which tend to be larger, bilateral, multifocal and present at a younger age compared with sporadic forms. In addition, SEGA block the flow of fluid within the brain, causing a buildup of fluid and pressure that leads to blurred vision and seizures. In the current review, we describe the pathology of TSC disease in key organs and summarize the use of mTOR inhibitors to treat tumors in TSC patients. PMID:27698899

Pearson syndrome is a very rare metabolic disorder that is usually present in infancy with transfusion dependent macrocytic anemia and multiorgan involvement including exocrine pancreas, liver and renal tubular defects. The disease is secondary to a mitochondrial DNA deletion that is variable in size and location. Endocrine abnormalities can develop, but are usually not part of the initial presentation. We report two patients who presented with unusual endocrine manifestations, neonatal diabetes and adrenal insufficiency, who were both later diagnosed with Pearson syndrome. Medical records were reviewed. Confirmatory testing included: mitochondrial DNA deletion testing and sequencing of the breakpoints, muscle biopsy, and bone marrow studies. Case 1 presented with hyperglycemia requiring insulin at birth. She had several episodes of ketoacidosis triggered by stress and labile blood glucose control. Workup for genetic causes of neonatal diabetes was negative. She had transfusion dependent anemia and died at 24 months due to multisystem organ failure. Case 2 presented with adrenal insufficiency and anemia during inturcurrent illness, requiring steroid replacement since 37 months of age. He is currently 4 years old and has mild anemia. Mitochondrial DNA studies confirmed a 4.9 kb deletion in patient 1 and a 5.1 kb deletion in patient 2. The patients reported highlight the importance of considering mitochondrial DNA disorders in patients with early onset endocrine dysfunction, and expand the knowledge about this rare mitochondrial disease.

Germline mutations in PTPN11, the gene encoding the Src-homology 2 (SH2) domain-containing protein tyrosine phosphatase (SHP2), cause Noonan syndrome (NS), a relatively common, clinically variable, multisystem disorder. Here, we report on the identification of five different PTPN11 missense changes affecting residues Leu 261 , Leu 262 , and Arg 265 in 16 unrelated individuals with clinical diagnosis of NS or with features suggestive for this disorder, specifying a novel disease-causing mutation cluster. Expression of the mutant proteins in HEK293T cells documented their activating role on MAPK signaling. Structural data predicted a gain-of-function role of substitutions at residues Leu 262 and Arg 265 exerted by disruption of the N-SH2/PTP autoinhibitory interaction. Molecular dynamics simulations suggested a more complex behavior for changes affecting Leu 261 , with possible impact on SHP2's catalytic activity/selectivity and proper interaction of the PTP domain with the regulatory SH2 domains. Consistent with that, biochemical data indicated that substitutions at codons 262 and 265 increased the catalytic activity of the phosphatase, while those affecting codon 261 were only moderately activating but impacted substrate specificity. Remarkably, these mutations underlie a relatively mild form of NS characterized by low prevalence of cardiac defects, short stature, and cognitive and behavioral issues, as well as less evident typical facial features. © 2017 WILEY PERIODICALS, INC.

Visceral leishmaniasis is an infection with an insidious and disabling course caused by parasites of the genus Leishmania. In Europe, it is mostly associated with HIV infection. Systemic lupus erythematosus and its treatment are associated with increased risk of infection, neoplastic and concomitant autoimmune disorders. The association of these diseases may go unnoticed. A 60 year-old Caucasian woman with lupus presented with a one-year history of fever, malaise, weakness and weight loss. The highlights on physical examination were pallor, palpable hepatosplenomegaly and low-grade fever. Blood tests showed pancytopenia, hyperproteinemia with hypoalbuminemia and hypergammaglobulinemia; electrophoresis showed a polyclonal gamma curve. Full-body CT scan revealed massive hepatosplenomegaly. Microbiology investigation was negative for the most common pathogens, including tuberculosis. There were no signs of hematologic malignancy in the bone marrow smear. PCR for Leishmania infantum was positive both in blood and bone marrow. The patient was treated with liposomal amphotericin B, and immunosuppression was adjusted. She showed rapid clinical improvement and 6 months later had no signs of disease. The differential diagnosis in a patient with lupus presenting with fever and multisystemic manifestations includes infectious or neoplastic disorders. The patient lived in an endemic area of Leishmania, and typical clinical and analytical changes were all present, making this case highly educational. The case highlights the importance of a patient's epidemiological background and how it can lead to the diagnosis and timely treatment of a rare disease.

Primary glomerulopathies are those disorders that affect glomerular structure, function, or both in the absence of a multisystem disorder. We aimed to evaluate the frequency of MEFV gene mutation to show possible coexistence of FMF in patients diagnosed with biopsy-proven primary glomerulonephritis (GN). A total of 64 patients with biopsy-proven primary GN were included in the study. MEFV gene mutations examined retrospectively. The mean age of patients was 39.6 ± 13.4 (range 18-69), 35 of patients were female and 29 of patients were male. Of the 64 patients, 17 were mesangial proliferative glomerulonephritis (MsPGN), 15 were IgA nephropathy (IgAN), 12 were membranous glomerulonephritis (MGN), 11 were focal segmental glomerulosclerosis (FSGS), three were membranous proliferative glomerulonephritis (MPGN), three were immune complex glomerulonephritis (ICGN), two were minimal change disease (MCD), and one was IgM nephropathy (IgMN). MEFV gene mutation was detected in 35.9% (23) of these patients. The most frequently detected mutations were E148Q and M694V. Twelve cases (18.75% of GN patients) with MEFV gene mutation were diagnosed as FMF phenotype I. The frequency of MEFV gene mutation was detected at a high rate of 35.9%. Further studies with larger populations are needed to clarify the importance of these mutations on clinical progression of glomerulonephritis.

Not only in newborns with Down syndrome, but newborns without phenotypic features of Down syndrome also develop transient myeloproliferative disorder (TMD). In these cases, trisomy 21 and related chromosomal abnormalities are either constitutionally mosaic or limited to blood cells. Risk factors for early death of these patients are unknown so far. We here report a fatal case of TMD without phenotypic features of Down syndrome and review literature to identify risk factors associated with early death. Not only are gestational age and white blood cell count risk factors for early death in TMD with Down syndrome, but they also appear to be risk factors in TMD without Down syndrome.

Clinical management of aplastic anemia

Acquired aplastic anemia is a potentially fatal bone marrow failure disorder that is characterized by pancytopenia and a hypocellular bone marrow. Hematopoietic stem-cell transplantation or bone marrow transplantation (BMT) is the treatment of choice for young patients who have a matched sibling donor. Immunosuppression with either anti-thymocyte globulin and cyclosporine or high-dose cyclophosphamide is an effective therapy for patients who are not suitable BMT candidates owing to age or lack of a suitable donor. Results of BMT from unrelated and mismatched donors are improving, but presently this treatment option is best reserved for those patients who do not respond, relapse or develop secondary clonal disorders following immunosuppressive therapy. Efforts are currently underway to both improve immunosuppressive regimens and to expand the application of BMT. PMID:21495931

Measles, mumps, rubella, and human parvovirus B19 infections and neurologic disease.

PubMed

Bale, James F

While the systemic disorders associated with measles, mumps, and rubella viruses and human parvovirus B19 tend to be mild, each virus can produce potentially life-threatening neurologic disease in human hosts, especially when these viruses infect young children. Two of the viruses, rubella and parvovirus B19, can be vertically transmitted to fetuses during maternal infection and cause congenital infection. Neurologic complications are common after intrauterine infection with the rubella virus, a condition known as the congenital rubella syndrome. Two, measles and rubella viruses, can induce "slow viral" infections, serious, disorders that can occur several years after the initial exposure to the virus and typically have fatal outcomes. © 2014 Elsevier B.V.

Churg-Strauss syndrome (CSS) is a rare multisystem vasculitis. Considering the variation of autoimmune diseases in different races, it is of interest to determine whether any outstanding features exist for Turkish patients with CSS. The aim of this study was to evaluate the clinical and serological features of the disease, the treatment, and long-term follow-up details, and to investigate possible etiological factors of Turkish CSS patients. The study included 14 patients who were diagnosed with CSS, and followed by our department between 2004 and 2012. Possible etiological factors, initial symptoms, clinical presentations, treatment, as well as outcomes were documented. The study was approved by the local ethics. All patients fulfilled the American College of Rheumatology criteria. Initial symptoms were worsening asthma (n = 14; 100%) and skin lesions (n = 6; 43%). All patients had a diagnosis of asthma and nasal polyps, whereas 57.1% had aspirin hypersensitivity at the time of diagnosis. The lungs (100%) and skin (43%) were most commonly involved. Peripheral eosinophilia dominated on initial presentations of all patients. Initial treatments included oral methyl prednisolone in all cases, whereas cyclophosphamide and azathioprine were used in three cases. Relapses were detected in five cases. None of the cases were able to stop the oral corticosteroid treatment. No fatalities were observed. We herein describe a new severe asthma endotype in connection with CSS. We suggest that physicians who deal with uncontrolled severe asthma cases should consider CSS in the presence of nasal polyps, aspirin hypersensitivity, and especially peripheral blood eosinophilia over 10%. © 2014 John Wiley & Sons Ltd.
