    Full Text Available The major complication of Kawasaki disease is coronary artery dilatation and aneurysm. It occurs in approximately 15-25% of untreated children with Kawasaki Disease. Early diagnosis and treatment with Intravenous immune globulin (IVIG and aspirin (ASA can reduce the incidence of coronary artery abnormality to 2%-5%. We report one case of Atypical Kawasaki Disease with Multiple giant coronary artery aneurysms despite early adequate treatment with IVIG and ASA.

    Full Text Available The etiology of Kawasaki disease remains unknown despite extensive studies. Some researchers suggest that it is caused by an infectious agent. This is a case report where a patient with incomplete Kawasaki disease was found to have evidence compatible with acute Mycoplasma pneumoniae infection. This is one of the several case reports linking Mycoplasma pneumoniae to Kawasaki disease as a possible trigger. This is perhaps due to a superantigen or is mediated by some other mechanism. Accurate and timely testing for Mycoplasma infections is difficult and has its limitations. Despite this, Mycoplasma pneumoniae should be considered in the differential and workup for Kawasaki disease.

  9. Kawasaki disease - an Indian perspective.

    2009-07-01

    Kawasaki disease (KD) was first reported from Japan in 1967 by a young pediatrician, Tomisaku Kawasaki, while working at the Red Cross Hospital in Tokyo. Soon therafter, Marian Melish independently reported children with a similar clinical profile from Hawaii in the United States. KD has now been reported from all parts of the world, including several centers in India. Based on the epidemiology and clinical features, an infectious etiology has been suspected for long but no definitive causative agent has been implicated so far. Like many other vasculitides, the diagnosis of this condition is based on the recognition of a temporal sequence of clinical features, none of which is pathognomonic in isolation. KD is believed to be the commonest vasculitic disorder of children. Incidence rates as high as 60-150 per 100,000 children below 5 years of age have been reported from several countries. In India (as also perhaps in many other developing countries), however, majority of children with KD continue to remain undiagnosed probably because of the lack of awareness amongst pediatricians. The clinical features of KD can be confused with other common conditions like scarlet fever and the Stevens Johnson syndrome, if the clinician is not careful. Development of coronary artery abnormalities (CAA) is the hallmark of KD and accounts for most of the morbidity and mortality associated with the disease. Prompt recognition of the disease and early initiation of treatment with intravenous immunoglobulin (IVIG) results in significant reduction in the occurrence of CAA. It is, therefore, imperative for the pediatrician to diagnose and treat KD expeditiously. KD should be considered in the differential diagnosis of all febrile illnesses in young children where the fever persists for more than 5-7 days.

  10. Kawasaki Disease: A Clinician’s Update

    Full Text Available Aims. Kawasaki disease is an acute systemic vasculitis and is the most common cause of acquired heart disease in children in the developed world. This review aims to synthesise recent insights into the disease and provide an update for clinicians on diagnostic and treatment practices. Methods. We conducted a review of the literature exploring epidemiology, aetiology, diagnosis, and management of Kawasaki disease. We searched MEDLINE, Medline In-Process, Embase, Google Scholar, and reference lists of relevant articles. Conclusions. Kawasaki disease is a febrile vasculitis which progresses to coronary artery abnormalities in 25% of untreated patients. The disease is believed to result from a genetically susceptible individual’s exposure to an environmental trigger. Incidence is rising worldwide, and varies widely across countries and within different ethnic groups. Diagnosis is based on the presence of fever in addition to four out of five other clinical criteria, but it is complicated by the quarter of the Kawasaki disease patients with “incomplete” presentation. Treatment with intravenous immunoglobulin within ten days of fever onset improves clinical outcomes and reduces the incidence of coronary artery dilation to less than 5%. Given its severe morbidity and potential mortality, Kawasaki disease should be considered as a potential diagnosis in cases of prolonged paediatric fever.

  11. Sensorineural hearing loss in Kawasaki disease.

    2016-01-01

    Kawasaki disease is a common nonspecific vasculitis seen in childhood. The most significant long-term sequela is coronary artery aneurysm. However, the spectrum of complications involves not only the heart, but also other organs such as the eyes, skin, kidneys, gallbladder, liver, and central nervous system. Sensorineural hearing loss (SNHL) is a relatively unrecognized complication of the disease. Although most of the complications (except coronary artery aneurysm) are self-limiting, SNHL can be persistent. It is, especially important in infants and young children who might not be able to report the hearing deficits and are most likely to have cognitive and speech delays if this hearing loss is not addressed in a timely manner. We report a child with Kawasaki disease who had SNHL during the 2(nd) week of the illness. The aim of this article is to briefly review the pathophysiology behind this hearing loss and strongly emphasize the importance of universal hearing evaluation in all children diagnosed with Kawasaki disease. This screening in children with Kawasaki disease may provide some timely intervention if needed. Since most Kawasaki disease patients will be seen by cardiologists, we hope to create more awareness about this complication to the cardiology community as well. PMID:27011703

    Full Text Available A doença de Kawasaki é vasculite sistêmica e aguda de etiologia desconhecida. Constitui a principal causa de doença cardíaca adquirida em crianças nos EUA. Ocorre mais frequentemente em meninos, 80% dos casos em crianças com menos de cinco anos, sendo rara após os oito anos. Pode atingir crianças de todas as raças, tendo maior incidência entre os descendentes asiáticos. Caracteriza-se por febre, conjuntivite bilateral não exsudativa, eritema e edema de língua, lábios e mucosa oral, alterações de extremidades, linfonodomegalia cervical, exantema polimórfico. Aneurismas e estenoses de artérias coronárias são comuns em percentual que varia de 20 a 25% dos pacientes não tratados, podendo posteriormente levar a infarto agudo do miocárdio e morte súbita. O tratamento com imunoglobulina intravenosa é efetivo e deve ser iniciado precocemente a fim de evitar sequelas cardíacas. O desenvolvimento de testes diagnósticos, terapêuticas mais específicas e a prevenção dessa doença potencialmente fatal em crianças dependem dos contínuos avanços na determinação de sua etiopatogenia.Kawasaki disease is a systemic acute vasculitis of unknown etiology. It is the leading cause of acquired heart disease in children in the USA. It occurs more frequently in boys and eighty percent of the cases occur in children under five years of age. The disease rarely occurs after eight years and it can affect children of all races, with higher incidence among Asian descendants. Kawasaki disease is characterized by fever, bilateral non-exudative conjunctivitis, redness and swelling of the tongue, lips and oral mucosa, abnormalities in the extremities, cervical lymph node, and polymorphic exanthema. Aneurysms and stenoses of coronary arteries occur in pproximately 20 to 25% of untreated patients and subsequently can lead to acute myocardial infarction and sudden death.

    Kawasaki disease, also known as cutaneous-mucous-glandular mucocutaneous glandular syndrome, is acute systemic vasculitis of small-to-medium calibre arteries, frequently involving coronary arteries, affect almost exceptionally children, with reports concerning cases of Kawasaki syndrome in 20-to-30-year-old adults being extremely rare. The most serious manifestation of Kawasaki disease is coronaritis and formation of coronary artery aneurysms. The dynamics of the formed coronary aneurysms and, consequently, the fate of patients may be different. Thrombosis of an aneurysm in the early period of the disease and stenosing of the affected coronary artery later on present possible complications of Kawasaki disease and potential causes of myocardial infection in young adults. Increased risk of coronary artery thromboses in Kawasaki disease is conditioned by a decrease in velocity of blood flow and its turbulent pattern in the aneurysms, endothelial dysfunction due to currently existing or endured coronaritis and thrombocytosis typical of this pathology. Predisposing factors of coronary artery stenosing are unfavourable haemodynamic conditions appearing at the sites of the "entry" and "exit" of the aneurysm. Described herein are two case reports of myocardial infarction, one of which being a complication of an acute case of Kawasaki disease in a 29-year-old patient, with the second one being a consequence of coronary artery stenosing in a 25-year-old patient who had endured Kawasaki disease in his childhood.

    Background Kawasaki disease (KD) is the leading cause of pediatric ischemic heart disease. The incidence of serious coronary sequelae is low and about 2%-3% of patients with KD, but once myocardial infarction occurs in children, the mortality is quite high and 22% at the first infarction.This study aimed to evaluate the efficacy of coronary artery bypass grafting (CABG) in patients with KD.Methods Eight patients with a history of KD underwent CABG between October 1997 and July 2005. The number of bypass grafts placed was 2 to 4 per patient (mean 2.5±0.8). Various bypass grafts were used in patients, i.e. the left internal mammary artery (LIMA) in 3 patients, bilateral internal mammary artery (IMA) in 2 patients, LIMA plus gastroepiploic artery (GEA) in 1 patient and total saphenous vein grafts (SVGs) in 2 patients. The combined procedures included ventricular aneurysmectomy in 1 patient, mitral valve plasty in 1 and right coronary aneurysmectomy in 1. One patient was not able to wean from cardiopulmonary bypass (CPB), after being supported with intra-aortic balloon pump (IABP), the patient was weaned from CPB successfully.Results One patient died of low cardiac output syndrome and acute renal failure 19 days after operation. Other patients recovered and were discharged uneventfully. During the follow-up that ranged from 3 to 57 months (mean 27 months),clincal angina disappeared or improved. Cardiac function was in Class Ⅰ-Ⅱ (NYHA).Conclusion CABG is a safe and effective procedure for Kawasaki coronary artery disease. However long-term results need to be followed up.

    Full Text Available Introduction: Kawasaki disease is an acute, systemic vacuity that predominantly manifests in infants and young children. Severe systemic inflammation and vacuities can cause cardiovascular involvement, particularly coronary artery injury that includes dilatation or aneurysm. The final goal of treatment for acute Kawasaki disease، therefore، is to diminish systemic inflammation and vacuities as soon as possible, thereby, preventing progression to coronary artery injury and thrombosis.Case Report: In this report we present a case of Kawasaki disease in a 7-year-old boy with prolonged fever and cervical adenopathy presented with erythema marginatum as a first skin presentation. We treated the patient with intravenous gamma-globulin (IVIG by six day after admission. He developed cardiac and pulmonary involvement two days later.Conclusion: Any skin rash is described in Kawasaki disease except for bullous and vesicular lesions. The common skin manifestation of Kawasaki disease are erythematous and maculopapular rash, although it may appear urticarial, scarlatiniform, erythema multiforme-like, or as erythroderma. Erythema marginatum had a limited differential diagnosis in pediatric patients. The major cause of erythema marginatum is rheumatic fever but there is no report of erythema marginatum in face and cervical region and Kawasaki disease should be considered in differential diagnosis of erythema marginatum in face and neck.

  20. Cardiospect (CS) in Pediatrics. Kawasaki Disease (KD)

    International Nuclear Information System (INIS)

    The first publication of the EK was in the year 1967, by T. Kawasaki, referring to 50 cases and establishing clinical diagnostic criteria of the disease, including cardiac involvement. In 1968 T. Yamamoto published a series of cases of EK, in which 48% had electrocardiographic abnormalities, establishing that the cardiac involvement was a common occurrence in this disease. The international incidence is between 1 and 5 per 100 000 and mortality between 0.1% and 5% difference related to the study and better recognition and hence early and appropriate treatment in countries where EK is more frequent. Mortality is higher in men and in children under one year old. The cardiac manifestations are one of the most important EK: approximately 15-25% of untreated children develop coronary abnormalities, acute myocardial infarction and myocarditis. Studies of CS can be used to assess myocardial ischemia or viability within the context of stress with dipyridamole or rest study in patients with acute symptoms or follow-up post revascularization. Thus it follows a forecast or defining complications. We present the cases of three patients with KD seen in the past year at our institution who had related heart disease and who underwent CS studies. It describes the technical findings and local acquisition, processing and diagnostic and clinical relevance. (author)

    Kawasaki disease is an acute self-limiting systemic vasculitis. It is the most common cause of acquired heart disease, with the risk of developing coronary artery aneurysms, myocardial infarction and sudden death. Diagnosis is based on the presence of fever in addition to other clinical criteria. The quarter of the Kawasaki disease patients have "incomplete" presentation. Treatment with intravenous immunoglobulin within ten days of fever onset improves clinical outcomes and reduces the incidence of coronary artery dilation to less than 5%. Non-responders to standard therapy have shown a successful response with the use of corticosteroids and/or biological agents. The long-term management must be delineated according to the degree of coronary involvement in a multidisciplinary manner. To facilitate the pediatrician's diagnosis, treatment and monitoring of Kawasaki disease, a group of experts from the Argentine Society of Pediatrics and the Argentine Society of Cardiology carried out a consensus to develop practical clinical guidelines.

    International Nuclear Information System (INIS)

    Although the incidence of coronary artery aneurysms has diminished in patients with Kawasaki disease, coronary artery involvement is still regarded as a major complication of the disease, significantly affecting morbidity and mortality. Recent technical advances in coronary CT angiography (CTA) and MR angiography (MRA) have led to the possibility of using these two imaging methods as minimally invasive alternatives to the more invasive diagnostic catheter angiography in evaluating coronary artery abnormalities, such as aneurysm, stenosis, and occlusion. In this article, we describe imaging techniques and findings of coronary CTA and MRA in Kawasaki disease. (orig.)

    To retrospectively compare the imaging characteristics of retropharyngeal density and associated findings for Kawasaki disease with those for non-Kawasaki disease, and identify the distinguishing features which aid the CT diagnosis of Kawasaki disease with retropharyngeal low density. Among the enhanced neck CT performed in children less than 8-years old with clinical presentation of fever and cervical lymphadenopathy over a 6-year period, only cases with retropharyngeal low density (RLD) were included in this study. The 56 cases of RLD were divided into two groups; group A included cases diagnosed as Kawasaki disease (n = 34) and group B included cases diagnosed as non-Kawasaki disease (n = 22). We evaluated the CT features including the thickness of RLD and its extent into the deep neck spaces, as well as soft tissue change in the adjacent structure. We also scored the extent of RLD into the deep neck spaces and the soft tissue changes in the adjacent structure. The thickness of RLD was greater in group A than in group B (group A, 6.0 {+-} 2.1; group B, 4.6 {+-} 1.5, p = 0.01). The score of the RLD extent into the deep neck spaces was significantly greater in group A than in group B (group A, 2.3 {+-} 1.3; group B, 0.8 {+-} 1.0, p < 0.01). Also, the score of the adjacent soft tissue changes was greater in group A than in group B (group A, 2.0 {+-} 1.1; group B, 1.0 {+-} 1.0, p < 0.01). If children present with fever and cervical lymphadenopathy that display retropharyngeal low density with extension into more deep neck spaces as well as changes in more adjacent soft tissue, the possibility of Kawasaki disease should be considered.

    Over the last 20 years, Kawasaki disease is being increasingly recognized in India and it may soon replace acute rheumatic fever to become the commonest cause of acquired heart disease amongst children. However, the vast majority of children with Kawasaki disease in India are still not being diagnosed. Diagnosis of Kawasaki disease is based on a constellation of clinical findings which have a typical temporal sequence. All pediatricians must we familiar with the nuances involved in arriving at a diagnosis of Kawasaki disease. With early diagnosis and prompt treatment, the risk of coronary artery abnormalities can be significantly reduced. PMID:26897142

    Kawasaki disease is an acute febrile vasculitis of infancy and early childhood. It is uncommon in early infancy, because a significant proportion of these children do not meet the classical diagnostic criteria at this age. Infants younger than 6 months with persistent fever and some of the criteria of Kawasaki disease should always raise suspicion for Kawasaki disease early to avoid delayed diagnosis with severe cardiac complications. We present a 35-day-old infant with incomplete Kawasaki disease complicated with myocardial infarction during chicken pox. PMID:20633312

    Kawasaki disease (KD) is a rare disease that occurs predominantly in infants and young children. To identify KD susceptibility genes and to develop a diagnostic test, a specific therapy, or prevention method, collecting KD patients’ clinical and genomic data is one of the major issues. For this purpose, Kawasaki Disease Database (KDD) was developed based on the efforts of Korean Kawasaki Disease Genetics Consortium (KKDGC). KDD is a collection of 1292 clinical data and genomic samples of 1283 patients from 13 KKDGC-participating hospitals. Each sample contains the relevant clinical data, genomic DNA and plasma samples isolated from patients’ blood, omics data and KD-associated genotype data. Clinical data was collected and saved using the common data elements based on the ISO/IEC 11179 metadata standard. Two genome-wide association study data of total 482 samples and whole exome sequencing data of 12 samples were also collected. In addition, KDD includes the rare cases of KD (16 cases with family history, 46 cases with recurrence, 119 cases with intravenous immunoglobulin non-responsiveness, and 52 cases with coronary artery aneurysm). As the first public database for KD, KDD can significantly facilitate KD studies. All data in KDD can be searchable and downloadable. KDD was implemented in PHP, MySQL and Apache, with all major browsers supported. Database URL: http://www.kawasakidisease.kr

For this purpose, Kawasaki Disease Database (KDD) was developed based on the efforts of Korean Kawasaki Disease Genetics Consortium (KKDGC). KDD is a collection of 1292 clinical data and genomic samples of 1283 patients from 13 KKDGC-participating hospitals. Each sample contains the relevant clinical data, genomic DNA and plasma samples isolated from patients' blood, omics data and KD-associated genotype data. Clinical data was collected and saved using the common data elements based on the ISO/IEC 11179 metadata standard. Two genome-wide association study data of total 482 samples and whole exome sequencing data of 12 samples were also collected. In addition, KDD includes the rare cases of KD (16 cases with family history, 46 cases with recurrence, 119 cases with intravenous immunoglobulin non-responsiveness, and 52 cases with coronary artery aneurysm). As the first public database for KD, KDD can significantly facilitate KD studies. All data in KDD can be searchable and downloadable. KDD was implemented in PHP, MySQL and Apache, with all major browsers supported.Database URL: http://www.kawasakidisease.kr. PMID:27630202

    1988-01-01

    Renal involvement is well described in patients with mucocutaneous lymph node syndrome (MCLNS), or Kawasaki disease and is manifested by mild azotemia, hematuria, pyuria or cylinduria, and more often, proteinuria. Renal morphology during the acute stages of the illness has never been reported. In this paper we describe the renal histopathologic changes in a child with MCLNS. The glomerular histopathologic findings suggest immune complex damage to the kidney as a possible mechanism of nephrotoxicity in MCLNS. Presence of kidney lesions, which speak in favor of the injurious role of immune complexes in MLCNS may be relevant to the understanding of the pathogenesis of the vascular lesions that are characteristic of this disease.

    A 40-year-old Mauritanian man consulted for back pain. A computed tomography of the spine showed patchy sclerosis of the fifth and seventh thoracic vertebral bodies with normal neural arch of T5 and sclerosis and hypertrophy of the neural arch of T7, as well as diffuse sclerosis of the T11 vertebral body with a normal neural arch. At MRI, low signal-intensity on T1-weighted images and high signal-intensity on T2-weighted images involved the whole T5 and T7 vertebrae and the vertebral body of T11. Working diagnoses included metastatic disease and lymphoma, and a biopsy of T7 and then T11 was carried out. Both showed pathological findings very suggestive of Paget's disease. Since CT is usually the more specific radiological examination in vertebral Paget's disease, we thought it could be useful to report this atypical CT presentation (patchy sclerosis of the vertebral body without diffuse bone texture changes and isolated involvement of the vertebral body) of vertebral Paget's disease.

    @@Kawasaki disease (muco-cutaneous lymph node syndrome, MCLS) was first reported by Kawasaki in 1967. It was characteried by nonvascular polymorphous rash, fever, ulcer in oral mucosa, edema of hands of feet, cervix lymphadenopathy and desquamations in peripheral extremities. Because of unknown pathogens, no lab examination was available as a single easily recognized diagnostic marker; the diagnosis is based on clinical features. The main complication of Kawasaki disease is coronary artery (CA) lesion; the prognosis is determined by the degree of pathological change of the coronary artery[1.2].

    Full Text Available Incomplete Kawasaki disease (iKD is considered to be a less complete form of Kawasaki disease (cKD, and several differences in the laboratory presentations of iKD and cKD have been noted. We investigated serum procalcitonin levels in patients with iKD, cKD, and other febrile diseases (a control group. Seventy-seven patients with cKD, 24 with iKD, and 41 controls admitted to our hospital from November 2009 to November 2011 were enrolled in the present study. We obtained four measurements of serum procalcitonin levels and those of other inflammatory markers from each patient. Samples were taken for analysis on the day of diagnosis (thus before treatment commenced; D0 and 2 (D2, 14 (D14, and 56 days (D56 after intravenous immunoglobulin infusion. We obtained control group data at D0. The mean D0 serum procalcitonin levels of cKD patients (0.71±1.36 ng/mL and controls (0.67±1.06 ng/mL were significantly higher than those of iKD patients (0.26±0.26 ng/mL (P=0.014 and P=0.041, resp.. No significant difference in mean procalcitonin level was evident among groups at any subsequent time. In conclusion, the serum procalcitonin level of patients with acute-stage cKD was significantly higher than that of iKD patients.

    Full Text Available We describe a patient with Kawasaki disease (KD and retropharyngeal edema following a blackfly bite. An 8-year-old boy was referred to our hospital because of a 3-day-history of fever and left neck swelling and redness after a blackfly bite. Computed tomography of the neck revealed left cervical lymph nodes swelling with edema, increased density of the adjacent subcutaneous tissue layer, and low density of the retropharyngeum. The patient was initially presumed to have cervical cellulitis, lymphadenitis, and retropharyngeal abscess. He was administered antibiotics intravenously, which did not improve his condition. The patient subsequently exhibited other signs of KD and was diagnosed with KD and retropharyngeal edema. Intravenous immunoglobulin therapy and oral flurbiprofen completely resolved the symptoms and signs. A blackfly bite sometimes incites a systemic reaction in humans due to a hypersensitive reaction to salivary secretions, which may have contributed to the development of KD in our patient.

    Kawasaki disease is an acute, self-limiting vasculitis of unknown origin, characterized by fever, palms and soles edema, cervical lymphadenopathy, strawberry tongue, and non-exudative conjunctivitis. It is a multisystemic vasculitis that affects predominantly infants and young children. The most feared complication is the development of coronary aneurysms that occurs up to 25% of untreated patients; however there are reports of extra coronary involvement. Herein we present the case of a 2 year-old girl who had a severe symptomatology and persistent fever despite intravenous gammaglobulin. Two years later she presented right hemiparesia and headache, with data from CAT and MRI suggestive of brain mass and deviation of the midline, secondary to left frontoparietal haemorrhage that was treated with a craniotomy. She was discharged on prednisone, ASA and rehabilitation.

    Full Text Available Objective: The association between Kawasaki disease and autism has rarely been studied in Asian populations. By using a nationwide Taiwanese population-based claims database, we tested the hypothesis that Kawasaki disease may increase the risk of autism in Taiwan. Materials and Methods: Our study cohort consisted of patients who had received the diagnosis of Kawasaki disease (ICD-9-CM: 446.1 between 1997 and 2005 (N = 563. For a comparison cohort, five age- and gender-matched control patients for every patient in the study cohort were selected using random sampling (N = 2,815. All subjects were tracked for 5 years from the date of cohort entry to identify whether they had developed autism (ICD-9-CM code 299.0 or not. Cox proportional hazard regressions were then performed to evaluate 5-year autism-free survival rates. Results: The main finding of this study was that patients with Kawasaki disease seem to not be at increased risk of developing autism. Of the total patients, four patients developed autism during the 5-year follow-up period, among whom two were Kawasaki disease patients and two were in the comparison cohort. Further, the adjusted hazard ratios (AHR (AHR: 4.81; 95% confidence interval: 0.68–34.35; P = 0.117 did not show any statistical significance between the Kawasaki disease group and the control group during the 5-year follow-up. Conclusion: Our study indicated that patients with Kawasaki disease are not at increased risk of autism.

Methods: The hospital records of patients who were hospitalized with the diagnosis of KD in the Pediatrics Clinics of Konya Training and Research Hospital between May 2010 and June 2012 were reviewed retrospectively. Results: Seven cases were found to have the diagnosis of KD, two of whom were incomplete KD. Oropharynx changes were the most common (100% feature in our patients. Five (71% patients had bulbar conjunctivitis. Three (43% patients had erythema at the site of BCG inoculation. Adenopathy was present in all of our patients with the classical form. A desquamation was observed in one case at the seventh day of fever. No cardiac manifestation was seen. Elevated erythrocyte sedimentation rate and thrombocytosis were present in all patients. All of the patients were received intravenous immunoglobulin in the first ten days of the fever. Conclusion: KD should be considered as a possible diagnosis in any child presenting with prolonged fever. BCG reaction can be attributed as a diagnostic criterion for incomplete form of the disease especially in countries where BCG vaccination is routinely performed. Early treatment is essential to prevent cardiovascular complications.

    Full Text Available BACKGROUND: Kawasaki disease is an acute, self-limited vasculitis of childhood that can result in structural damage to the coronary arteries. Previous studies have implicated the TGF-β pathway in disease pathogenesis and generation of myofibroblasts in the arterial wall. microRNAs are small non-coding RNAs that modulate gene expression at the post-transcriptional level and can be transported between cells in extracellular vesicles. To understand the role that microRNAs play in modifying gene expression in Kawasaki disease, we studied microRNAs from whole blood during the acute and convalescent stages of the illness. METHODOLOGY/PRINCIPAL FINDINGS: RNA isolated from the matched whole blood of 12 patients with acute and convalescent Kawasaki disease were analyzed by sequencing of small RNA. This analysis revealed six microRNAs (miRs-143, -199b-5p, -618, -223, -145 and -145* (complementary strand whose levels were significantly elevated during the acute phase of Kawasaki disease. The result was validated using targeted qRT-PCR using an independent cohort (n = 16. miR-145, which plays a critical role in the differentiation of neutrophils and vascular smooth muscle cells, was expressed at high levels in blood samples from acute Kawasaki disease but not adenovirus-infected control patients (p = 0.005. miR-145 was also detected in small extracellular vesicles isolated from acute Kawasaki disease plasma samples. Pathway analysis of the predicted targets of the 6 differentially expressed microRNAs identified the TGF-β pathway as the top pathway regulated by microRNAs in Kawasaki disease. CONCLUSION: Sequencing of small RNA species allowed discovery of microRNAs that may participate in Kawasaki disease pathogenesis. miR-145 may participate, along with other differentially expressed microRNAs, in regulating expression of genes in the TGF-β pathway during the acute illness. If the predicted target genes are confirmed, our findings suggest a model of

    Full Text Available Objective. Kawasaki disease (KD is a multisystemic autoimmune vasculitis. Intravenous immunoglobulin (IVIG is the first-line treatment for KD. It is unclear whether traditional Chinese medicine (TCM has an effect on KD. We aimed to observe the clinical efficacy of TCM on acute KD via serum interleukin-33 (IL-33 and tumor necrosis factor alpha (TNF-α measurements. Methods. Thirty-one KD patients were treated with Qing Re Liang Xue decoction and Western medicine (integrative medicine treatment group, while 28 KD patients were treated with Western medicine only (Western medicine treatment group. Thirty patients were included in a febrile group and 28 healthy children were included in the control group. Clinical characteristics and laboratory findings were gathered and compared. Serum IL-33 and TNF-α levels were measured by multiplex Luminex assay. Results. The platelet count in the integrative medicine treatment group was significantly lower than that in the Western medicine treatment group. The integrative medicine group had a shorter fever duration and lower IL-33 and TNF-α levels than those in the Western medicine group, but there were no significant differences between the two KD groups after treatment. Conclusion. Qing Re Liang Xue decoction improved the hypercoagulable state of KD patients. Potential myocardial protective effects require further research.

    Kawasaki disease (KD; MIM#61175) is a systemic vasculitis syndrome with unknown etiology which predominantly affects infants and children. Recent findings of susceptibility genes for KD suggest possible involvement of the Ca(2+)/NFAT pathway in the pathogenesis of KD. ORAI1 is a Ca(2+) release activated Ca(2+) (CRAC) channel mediating store-operated Ca(2+) entry (SOCE) on the plasma membrane. The gene for ORAI1 is located in chromosome 12q24 where a positive linkage signal was observed in our previous affected sib-pair study of KD. A common non-synonymous single nucleotide polymorphism located within exon 2 of ORAI1 (rs3741596) was significantly associated with KD (P = 0.028 in the discovery sample set (729 KD cases and 1,315 controls), P = 0.0056 in the replication sample set (1,813 KD cases vs. 1,097 controls) and P = 0.00041 in a meta-analysis by the Mantel-Haenszel method). Interestingly, frequency of the risk allele of rs3741596 is more than 20 times higher in Japanese compared to Europeans. We also found a rare 6 base-pair in-frame insertion variant associated with KD (rs141919534; 2,544 KD cases vs. 2,414 controls, P = 0.012). These data indicate that ORAI1 gene variations are associated with KD and may suggest the potential importance of the Ca(2+)/NFAT pathway in the pathogenesis of this disorder. PMID:26789410

    2009-11-01

    Kawasaki disease (KD) is a serious pediatric illness affecting the cardiovascular system. One of the most serious complications of KD, occurring in about 25% of untreated cases, is the formation of large aneurysms in the coronary arteries, which put patients at risk for myocardial infarction. In this project we performed patient specific computational simulations of blood flow in aneurysmal left and right coronary arteries of a KD patient to gain an understanding about their hemodynamics. Models were constructed from CT data using custom software. Typical pulsatile flow waveforms were applied at the model inlets, while resistance and RCR lumped models were applied and compared at the outlets. Simulated pressure waveforms compared well with typical physiologic data. High wall shear stress values are found in the narrow region at the base of the aneurysm and low shear values occur in regions of recirculation. A Lagrangian approach has been adopted to perform particle tracking and compute particle residence time in the recirculation. Our long-term goal will be to develop links between hemodynamics and the risk for thrombus formation in order to assist in clinical decision-making.

    Kawasaki disease (KD) is an acute vasculitis affecting children. Incidence of KD varies according to ethnicity and is highest in Asian populations. Although genetic differences may explain this variation, dietary or environmental factors could also be responsible. The objectives of this study were to determine dietary soy and isoflavone consumption in a cohort of KD children just before disease onset and their mothers' intake during pregnancy and nursing. We tested the hypothesis that soy isoflavone consumption is associated with risk of KD in US children, potentially explaining some of the ethnic-cultural variation in incidence. We evaluated soy food intake and isoflavone consumption in nearly 200 US KD cases and 200 age-matched controls using a food frequency questionnaire for children and in their mothers. We used a logistic regression model to test the association of isoflavones and KD. Maternal surveys on soy intake during pregnancy and nursing showed no significant differences in isoflavone consumption between groups. However, we identified significantly increased KD risk in children for total isoflavone (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.37-3.96) and genistein (OR, 2.46; 95% CI, 1.46-4.16) intakes, when comparing high soy consumers vs nonconsumers. In addition, significantly increased KD risk occurred in Asian-American children with the highest consumption (total isoflavones: OR, 7.29; 95% CI, 1.73-30.75; genistein: OR, 8.33; 95% CI, 1.92-36.24) compared to whites. These findings indicate that childhood dietary isoflavone consumption, but not maternal isoflavone intake during pregnancy and nursing, relates to KD risk in an ethnically diverse US population.

    Kawasaki disease (KD) is a systemic vasculitis, classically affecting large- and medium-size arteries. The coronary arteries draw most of the clinical attention, whereas few studies have taken interest in the ascending aorta. Using a proprietary imaging-based mechanical biomarker (ImBioMark), we sought to determine aortic stiffness in KD compared to systemic hypertension (HTN) and healthy children. We evaluated parasternal long-axis views focused on the ascending aorta in 20 controls, 12 KD, and 8 HTN as a comparative clinical model of vascular stiffness. We calculated systolic and diastolic aortic wall strain with ImBioMark. Strain was tested for normality against height, systolic, and diastolic blood pressure in normal subjects. Strain from KD and HTN was normalized (Z score) accordingly. Z score comparisons were performed using nonparametric statistics. Age was similar between KD and HTN (9.1 ± 5.3 and 9.9 ± 5.3 years old; p = NS). Systolic and diastolic strain values were normally distributed against height, systolic blood pressure, and diastolic blood pressure in healthy subjects. HTN subjects had abnormal systolic and diastolic strain values (p < 0.0001). Whereas KD subjects had normal diastolic strain, systolic strain was significantly lower (p < 0.001), and systolic strain was intermediate between controls and HTN. There were no significant differences in aortic strain among KD, however, according to the presence of coronary artery aneurysms. Despite normal blood pressure, the ascending aorta in KD exhibits reduced strain during systole. This may reflect in situ rigidity of the aorta. The normal diastolic strain in KD may, in contrast, reflect normal peripheral vascular resistance. PMID:25921428

    We present a case of coronary ectasia and LAD coronary artery aneurysm with angiographic characteristics of Kawasaki disease in a three-yr-old girl two-yr status post-orthotopic heart transplant. Coronary anomalies were noted during initial screening coronary angiography two yr after transplant. Subsequent review of the donor echocardiogram revealed that the LMCA had been mildly dilated prior to transplant. In the absence of any symptoms consistent with Kawasaki disease in the transplant recipient, this appears to be a case of Kawasaki disease in the organ donor manifesting with coronary anomalies in the transplant recipient. The patient has done well clinically, and repeat coronary angiography has revealed partial regression of coronary anomalies. Given multiple reports in the literature of persistent abnormalities of coronary artery morphology and function after Kawasaki disease, close monitoring is warranted, with consideration of potential coronary protective medical therapies.

    2014-01-01

    Background: The comparative effectiveness of intravenous immunoglobulin (IVIG) for Kawasaki disease was regarded as inconclusive in the international guidelines. However, several new evidences have been published in recent years. Data sources: A literature search of PubMed was conducted using key words of "Kawasaki disease or mucocutaneous lymph node syndrome" and "immunoglobulin" in combination. Only original articles published after 2004 were selected. A total of 813 papers were found in PubMed. These papers were screened manually by their titles and abstracts. Results: Patients treated with IVIG prepared by betapropiolactonation might have worse outcome (a higher non-responsive rate in one report and a higher rate of coronary aneurysm in two reports). Storage of IVIG in acidic solution might be correlated with a higher rate of coronary aneurysm (two reports). Conclusions: Different processes of preparation and conditions of preservation of IVIG may have profound effects on its clinical effectiveness. Randomized controlled studies are needed to further elucidate this issue.

    Full Text Available Kawasaki disease (KD is characterized by pediatric systemic vasculitis of an unknown cause. The low affinity immunoglobulin gamma Fc region receptor II-a (FCGR2A gene was reported to be involved in the susceptibility of KD. DNA methylation is one of the epigenetic mechanisms that control gene expression; thus, we hypothesized that methylation status of CpG islands in FCGR2A promoter associates with the susceptibility and therapeutic outcomes of Kawasaki disease. In this study, 36 KD patients and 24 healthy subjects from out-patient clinic were recruited. Eleven potential methylation sites within the targeted promoter region of FCGR2A were selected for investigation. We marked the eleven methylation sites from A to K. Our results indicated that methylation at the CpG sites G, H, and J associated with the risk of KD. CpG sites B, C, E, F, H, J, and K were found to associate with the outcomes of IVIG treatment. In addition, CpG sites G, J, and K were predicted as transcription factors binding sites for NF-kB, Myc-Max, and SP2, respectively. Our study reported a significant association among the promoter methylation of FCGR2A, susceptibility of KD, and the therapeutic outcomes of IVIG treatment. The methylation levels of CpG sites of FCGR2A gene promoter should be an important marker for optimizing IVIG therapy.

    2010-11-01

    Kawasaki Disease is the leading cause of acquired pediatric heart disease, and can cause large coronary artery aneurysms in untreated cases. A simulation case study has been performed for a 10-year-old male patient with coronary aneurysms. Specialized coronary boundary conditions along with a lumped parameter heart model mimic the interactions between the ventricles and the coronary arteries, achieving physiologic pressure and flow waveforms. Results show persistent low shear stress in the aneurismal regions, and abnormally high shear at the aneurysm neck. Correlation functions have been derived to compare wall shear stress and wall shear stress gradients with recirculation time with the idea of localizing zones of calcification and thrombosis. Results are compared with those of an artificially created normal coronary geometry for the same patient. The long-term goal of this work is to develop links between hemodynamics and thrombotic risk to assist in clinical decision-making.

    Herein we describe the case of a 6-week-old boy who developed complete Kawasaki disease (KD). The cytokine profile and activation of monocytes and subsequent T cells matched the typical feature of refractory KD. The patient received a total of three courses of i.v. immunoglobulin (IVIG), but did not achieve clinical relief. Adjunctive therapy with oral cyclosporine A (CsA) led to prompt defervescence. This was continued for 7 days without serious adverse events. Coronary artery dilatations regressed within 3 months of follow up. KD infants aneurysm than the older ones. To our knowledge, oral CsA treatment has not been reported in such young infants with KD. The diagnosis and treatment of very young infants with KD are challenging. Adjunctive use of CsA in IVIG treatment could be effective for refractory KD in infants <3 months of age. PMID:26670024

    To perform experimental validation of computational fluid dynamics (CFD) applied to patient specific coronary aneurysm anatomy of Kawasaki disease. We quantified hemodynamics in a patient-specific coronary artery aneurysm physical phantom under physiologic rest and exercise flow conditions. Using phase contrast MRI (PCMRI), we acquired 3-component flow velocity at two slice locations in the aneurysms. We then performed numerical simulations with the same geometry and inflow conditions, and performed qualitative and quantitative comparisons of velocities between experimental measurements and simulation results. We observed excellent qualitative agreement in flow pattern features. The quantitative spatially and temporally varying differences in velocity between PCMRI and CFD were proportional to the flow velocity. As a result, the percent discrepancy between simulation and experiment was relatively constant regardless of flow velocity variations. Through 1D and 2D quantitative comparisons, we found a 5-17% difference between measured and simulated velocities. Additional analysis assessed wall shear stress differences between deformable and rigid wall simulations. This study demonstrated that CFD produced good qualitative and quantitative predictions of velocities in a realistic coronary aneurysm anatomy under physiological flow conditions. The results provide insights on factors that may influence the level of agreement, and a set of in vitro experimental data that can be used by others to compare against CFD simulation results. The findings of this study increase confidence in the use of CFD for investigating hemodynamics in the specialized anatomy of coronary aneurysms. This provides a basis for future hemodynamics studies in patient-specific models of Kawasaki disease. PMID:25050140

Because of the prolonged history of unexplained fever, rash, bilateral nonpurulent conjunctival injection, oropharyngeal erythema, strawberry tongue, and extreme of age, incomplete Kawasaki disease was considered and started on an intravenous immunoglobulin infusion. Six days after this treatment, patient was referred to eye clinic with decreased vision and photophobia. Visual acuity was reduced to 20/40 in both eyes. Slit-lamp examination revealed bilateral diffuse corneal punctate epitheliopathy and anterior stromal haze. Corneal epitheliopathy seemed like crystal deposits. One day after presentation, mild anterior uveitis was added to clinical picture. All ocular findings disappeared in one week with topical steroid and unpreserved artificial tear drops. We present a case who was diagnosed as incomplete Kawasaki disease along with bilateral diffuse crystalline-like keratopathy. We supposed that unusual ocular presentation may be associated with intravenous immunoglobulin treatment.

    2015-08-01

    Full Text Available Kawasaki disease (KD is an acute febrile illness of early childhood. Previous reports have suggested that genetic disease susceptibility factors, together with a triggering infectious agent, could be involved in KD pathogenesis; however, the precise etiology of this disease remains unknown. Additionally, previous culture-based studies have suggested a possible role of intestinal microbiota in KD pathogenesis. In this study, we performed metagenomic analysis to comprehensively assess the longitudinal variation in the intestinal microbiota of twenty-eight KD patients. Several notable bacterial genera were commonly extracted during the acute phase, whereas a relative increase in the number of Ruminococcus bacteria was observed during the non-acute phase of KD. The metagenomic analysis results based on bacterial species classification suggested that the number of sequencing reads with similarity to five Streptococcus spp. (S. pneumonia, pseudopneumoniae, oralis, gordonii, and sanguinis, in addition to patient-derived Streptococcus isolates, markedly increased during the acute phase in most patients. Streptococci include a variety of pathogenic bacteria and probiotic bacteria that promote human health; therefore, this further species discrimination could comprehensively illuminate the KD-associated microbiota. The findings of this study suggest that KD-related Streptococci might be involved in the pathogenesis of this disease.

    Full Text Available Objectives. The −420C>G polymorphism located in the resistin gene (RETN promoter has recently been suggested to play a potential role in proinflammatory conditions and cardiovascular disease. This study investigated the association of the RETN promoter polymorphism with Kawasaki disease (KD and its clinical parameters in Chinese children. Methods. We compared patients with complete KD to incomplete KD children. Genotyping of the RETN promoter polymorphism was performed using MassARRAY system, and serum resistin levels were estimated using the sandwich enzyme immunoassay method. Results. There was no significant difference in RETN (−420C>G genotypes between KD and control groups. However, the frequency of the G allele was higher in iKD patients than in cKD children due to a significantly increased frequency of the GG genotypes. Serum levels of resistin were significantly higher in KD patients than in controls regardless of the presence of coronary artery lesions (CALs. Conclusion. The present findings suggest that while resistin may play a role in the pathogenesis of KD, there is no apparent association between CAL and the RETN (−420C>G gene polymorphism in KD children. However, the diagnosis of iKD is challenging but can be supported by the presence of the G allele and the GG genotypes.

    1994-08-01

    To assess the frequency of hospital encoded diagnoses of acute rheumatic fever (ARF) and Kawasaki disease (KD), the two leading causes of acquired heart disease in children in the United States, we performed a survey of the medical record departments of United States children's hospitals and of general hospitals that have at least 400 beds and a pediatric ward. With a simple questionnaire, data were gathered for the years 1984 through 1990 by ICD.9CM codes, with a 58% response rate. About 8000 diagnoses of KD and 6000 diagnoses of ARF were encoded during the study period. Encoded diagnoses of both KD and ARF showed yearly fluctuations in the earlier years (1984 through 1987). For KD there was a general trend toward increasing numbers after 1986. These data are consistent with increased physician awareness and diagnosis of KD. For ARF a gradual decline was observed between 1986 and 1990. About 80% of ARF diagnoses were reported from general hospitals. The much smaller pool of encoded diagnoses of ARF at the children's hospitals showed a 56% increase from 1985 to 1986. These data suggest that the highly publicized increase in cases of acute rheumatic fever in the United States during the mid-1980s may reflect focal rather than nationwide increased activity and that nationally the number of diagnoses of ARF actually may have continued to decline gradually from 1984 through 1990.

    Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis. To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard. The study group comprised 12 patients (age 17.6 {+-} 2.9 years, mean{+-}SD) with a diagnosis of KD and a previously performed CCA (interval, 32.6 {+-} 13.5 months) who underwent 64-slice cardiac CTA. The quality of the images for establishing the presence of coronary abnormalities was determined by two observers. The CTA findings were compared with those from the prior CCA. Adequate image quality was obtained in all patients. Mean effective dose for CTA was 6.56 {+-} 0.95 mSv. CTA allowed accurate identification, characterization and measurement of all coronary aneurysms (n = 32), stenoses (n = 3) and occlusions (n = 9) previously demonstrated by CCA. One patient with disease progression went on to have percutaneous coronary intervention. Coronary lesions were reliably evaluated by 64-slice CTA in the follow-up of compliant patients with KD, reducing the need for repeated diagnostic invasive CCA. Hence, in an adequately selected patient population, the role of CCA could be limited almost only to therapeutic procedures. (orig.)

    Coronary artery aneurysms that occur in 25% of untreated Kawasaki disease (KD) patients may remain clinically silent for decades and then thrombose resulting in myocardial infarction. Although KD is now the most common cause of acquired heart disease in children in Asia, the United States, and Western Europe, the incidence of KD in Egypt is unknown. We tested the hypothesis that young adults in Egypt presenting with acute myocardial ischemia may have coronary artery lesions because of KD in childhood. We reviewed a total of 580 angiograms of patients ≤40 years presenting with symptoms of myocardial ischemia. Coronary artery aneurysms were noted in 46 patients (7.9%), of whom 9 presented with myocardial infarction. The likelihood of antecedent KD as the cause of the aneurysms was classified as definite (n = 10), probable (n = 29), or equivocal (n = 7). Compared with the definite and probable groups, the equivocal group had more traditional cardiovascular risk factors, smaller sized aneurysms, and fewer coronary arteries affected. In conclusion, in a major metropolitan center in Egypt, 6.7% of adults aged ≤40 years who underwent angiography for evaluation of possible myocardial ischemia had lesions consistent with antecedent KD. Because of the unique therapeutic challenges associated with these lesions, adult cardiologists should be aware that coronary artery aneurysms in young adults may be because of missed KD in childhood.

    Background Coronary artery damage from Kawasaki disease (KD) is closely linked to the dysfunction of endothelial progenitor cells (EPCs).The aim of the present study was to evaluate the therapeutic effect of EPCs transplantation in KD model.Methods Lactobacillus casei cell wall extract (LCWE)-induced KD model in C57BL/6 mice was established.The model mice were injected intravenously with bone marrow-derived in vitro expanded EPCs.Histological evaluation,number of circulating EPCs and the function of bone marrow EPCs were examined at day 56.Results Inflammation was found around the coronary artery of the model mice after 14 days,Elastin breakdown was observed after 56 days.CM-Dil labeled EPCs incorporated into vessel repairing foci was found.At day 56,the number of peripheral EPCs in the KD model group was lower than in EPCs transplanted and control group.The functional index of bone marrow EPCs from the KD model group decreased in proliferation,adhesion and migration.Increased number of circulating EPCs and improved function were observed on the EPCs transplanted group compared with model group.Conclusion Exogenously administered EPCs,which represent a novel strategy could prevent the dysfunction of EPCs,accelerate the repair of coronary artery endothelium lesion and decrease the occurrence of aneurysm.

  13. Chest X-ray findings in the acute phase of Kawasaki disease

    International Nuclear Information System (INIS)

    We reviewed the chest X-ray (CXR) findings and clinical courses of 129 patients with Kawasaki disease and found abnormal CXR findings in 14.7% of the patients. Reticulogranular pattern was the most frequent abnormality (89.5%), while peribronchial cuffing (21.1%), pleural effusion (15.8%), atelectasis (10.5%) and air trapping (5.3%) were also seen. In each of these patients, CXR abnormalities appeared within 10 days after the onset of illness. In the group with abnormal CXR findings, a statistically significant increase was noted in duration of fever, incidence of adventitious sounds, serum CPR levels and incidence of coronary arterial lesions and pericardial effusion, as compared with the group having normal CXR findings. The pathological basis of these CXR changes is not clear, since no biopsy or autopsy specimen was obtained from these patients. Since none of these patients showed definite heart failure, it is difficult to consider that abnormal CXR findings were due to heart failure. On the other hand, physical signs and previous pathological reports suggested that the causes of abnormal CXR findings were lower respiratory tract inflammation and/or pulmonary arteritis. (orig.)

    Kawasaki disease (KD) is a type of systemic vasculitis that primarily affects children under the age of five years old. For sufferers of KD, intravenous immunoglobulin (IVIG) has been found to successfully diminish the occurrence of coronary artery lesions. Anemia is commonly found in KD patients, and we have shown that in appropriately elevated hepcidin levels are related to decreased hemoglobin levels in these patients. In this study, we investigated the time period of anemia and iron metabolism during different stages of KD. A total of 100 patients with KD and 20 control subjects were enrolled in this study for red blood cell and hemoglobin analysis. Furthermore, plasma, urine hepcidin, and plasma IL-6 levels were evaluated using enzyme-linked immunosorbent assay in 20 KD patients and controls. Changes in hemoglobin, plasma iron levels, and total iron binding capacity (TIBC) were also measured in patients with KD. Hemoglobin, iron levels, and TIBC were lower (p hepcidin levels (both p hepcidin levels were positively and significantly correlated with urine hepcidin levels (p hepcidin and hemoglobin levels significantly decreased (both p hepcidin induces transient anemia and hypoferremia during KD's acute inflammatory phase.

    Kawasaki Disease (KD) can result in coronary aneurysms in up to 25% of patients if not treated early putting patients at risk of thrombus formation, myocardial infarction and sudden death. Clinical guidelines for administering anti-coagulation therapy currently rely on anatomy alone. Previous studies including patient specific modeling and computer simulations in KD patients have suggested that hemodynamic data can predict regions susceptible to thrombus formation. In particular, high Particle Residence Time gradient (PRTg) regions have shown to correlate with regions of thrombus formation. Transluminal Attenuation Gradient (TAG) is determined from the change in radiological attenuation per vessel length. TAG has been used for characterizing coronary artery stenoses, however this approach has not yet been used in aneurysmal vessels. The aim of this study is to analyze the correlation between TAG and PRTg in KD patients with aneurysms and evaluate the use of TAG as an index to quantify thrombotic risk. Patient specific anatomic models for fluids simulations were constructed from CT angiographic image data from 3 KD aneurysm patients and one normal control. TAG values for the aneurysm patients were markedly lower than for the non-aneurysmal patient (mean -18.38 vs. -2). In addition, TAG values were compared to PRTg obtained for each patient. Thrombotic risk stratification for KD aneurysms may be improved by incorporating TAG and should be evaluated in future prospective studies.

    Kawasaki Disease (KD) can result in coronary artery aneurysms (CAA) in up to 25% of patients, putting them at risk of thrombus formation, myocardial infarction and sudden death. Clinical guidelines recommend CAA diameter >8 mm as the arbitrary criterion for initiating systemic anticoagulation. KD patient specific modeling and flow simulations suggest that hemodynamic data can predict regions at increased risk of thrombosis. Transluminal Attenuation Gradient (TAG) is determined from the change in radiological attenuation per vessel length and has been proposed as a non-invasive method for characterizing coronary stenosis from CT Angiography. We hypothesized that CAA abnormal flow could be quantified using TAG. We computed hemodynamics for patient specific coronary models using a stabilized finite element method, coupled numerically to a lumped parameter network to model the heart and vascular boundary conditions. TAG was quantified in the major coronary arteries. We compared TAG for aneurysmal and normal arteries and we analyzed TAG correlation with hemodynamic and geometrical parameters. Our results suggest that TAG may provide hemodynamic data not available from anatomy alone. TAG represents a possible extension to standard CTA that could help to better evaluate the risk of thrombus formation in KD.

    Full Text Available Background Between 10 and 20% of children with Kawasaki disease (KD will not respond to intravenous immunoglobulin (IVIG treatment, and are prone to coronary abnormalities. A variety of predicting scoring systems, including the Kobayashi system, have been proposed, but have not yet been evaluated using Iranian patients. Objectives To evaluate the Kobayashi scoring system with regard to predicting response to IVIG treatment in Iranian children. Patients and Methods All patients who received a final diagnosis of KD at Aliasghar children’s hospital between 1982 and 2013, and who met the inclusion criteria, were enrolled in this retrospective cohort study. We excluded patients with missing data, abnormal echocardiographic finding on admission, late admission, atypical or afebrile cases, and those who had received an insufficient amount of IVIG. We compared demographic and echocardiographic data before IVIG, and within 7 days of treatment, as well as C reactive protein (CRP, sodium, aspartate aminotransferase, platelet levels, neutrophil percentage, age of patients, and duration of fever before IVIG administration, in treatment responders and non-responders. Results Of the 141 cases, 97 patients met the criteria and were enrolled. Of these, 19 (19.6% did not respond to IVIG. A total of 61.8% of patients were male, and the mean patient age was 36.9 months (SD = 32.1 months. Echocardiographic evaluation revealed early coronary involvement in 15.3% of patients, and coronary abnormalities were diagnosed in 10% of patients within the first 10 days of presentation and concurrent with their IVIG treatment. A between-groups comparison of quantitative CRP, absolute neutrophil count, and platelet count showed that platelet count alone was significantly higher in nonresponders (P = 0.04. With regard to items of Kobayashi scoring system, data were present for just 41 cases, but a significant difference between the two groups was shown, with the treatment

    Background Cardiovascular complications of Kawasaki disease (KD) are a common cause of heart disease in pediatric populations.Previous studies have suggested a role for endothelial progenitor cells (EPCs) in coronary artery lesions associated with KD.However,long-term observations of EPCs during the natural progression of this disorder are lacking.Using an experimental model of KD,we aimed to determine whether the coronary artery lesions are associated with down-regulation of EPCs.Methods To induce KD,C57BL/6 mice were administered an intraperitoneal injection of Lactobacillus casei cell wall extract (LCWE; phosphate buffered saline used as control vehicle).Study groups included:group A (14 days following LCWE injection),group B (56 days following LCWE injection) and group C (controls).Numbers of circulating EPCs (positively staining for both CD34 and FIk-1 while staining negative for CD45) were evaluated using flow cytometry.Bone marrow mononuclear cells were cultured in vitro to expand EPCs for functional analysis.In vitro EPC proliferation,adhesion and migration were assessed.Results The model was shown to exhibit similar coronary artery lesions to KD patients with coronary aneurysms.Numbers of circulating EPCs decreased significantly in the KD models (groups A and B) compared to controls ((0.017±0.008)% VS.(0.028±0.007)%,P<0.05 and (0.016±0.007)% vs.(0.028±0.007)%,P <0.05).Proliferative,adhesive and migratory properties of EPCs were markedly impaired in groups A and B.Conclusion Coronary artery lesions in KD occur as a consequence of impaired vascular injury repair,resulting from excess consumption of EPCs together with a functional impairment of bone marrow EPCs and their precursors.

    Full Text Available Purpose : Transforming growth factor beta receptor 2 (TGFBR2 is a tumor suppressor gene that plays a role in the differentiation of striated cells and remodeling of coronary arteries. Single nucleotide polymorphisms (SNPs of this gene are associated with Marfan syndrome and sudden death in patients with coronary artery disease. Cardiovascular remodeling and T cell activation of TGFBR2 gene suggest that the TGFBR2 gene SNPs are related to the pathogenesis of Kawasaki disease (KD and coronary artery lesion (CAL. Methods : The subjects were 105 patients with KD and 500 healthy adults as controls. Mean age of KD group was 32 months age and 26.6% of those had CAL. We selected TGFBR2 gene SNPs from serum and performed direct sequencing. Results : The sequences of the eleven SNPs in the TGFBR2 gene were compared between the KD group and controls. Three SNPs (rs1495592, rs6550004, rs795430 were associated with development of KD (P=0.019, P=0.026, P=0.016, respectively. One SNP (rs1495592 was associated with CAL in KD group (P=0.022. Conclusion : Eleven SNPs in TGFBR2 gene were identified at that time the genome wide association. But, with the change of the data base, only six SNPs remained associated with the TGFBR2 gene. One of the six SNPs (rs6550004 was associated with development of KD. One SNP associated with CAL (rs1495592 was disassociated from the TGFBR2 gene. The other five SNPs were not functionally identified, but these SNPs are notable because the data base is changing. Further studies involving larger group of patients with KD are needed.

    Kawasaki disease, although common in children, may rarely affect the coronary arteries, leading to aneurysm formation and potential for coronary thrombus formation. Extremely rarely, coronary aneurysms from Kawasaki disease can thrombose, resulting in ischemic myocardium. We present a case of a 31-month-old patient requiring a left ventricular assist device after thrombosis of giant coronary aneurysms led to ischemic cardiomyopathy. At the termination of the surgical procedure, we encountered 2 periods of ventricular assist device dropout requiring intervention. With the increase in the number of pediatric patients with assist devices, we review the basic care for a patient requiring emergent surgery. PMID:27310902

    Background:Coronary artery lesions (CALs) are known to be the main complication in children with Kawasaki disease (KD).Instead of intravenous immunoglobulin (IVIG),corticosteroid therapy has been accepted to be used for children with KD who are unresponsive to IVIG.This study aimed to evaluate risk factors for CALs in children with KD.Methods:We retrospectively reviewed the clinical records of 2331 children with KD from January 2005 to December 2014.To identify the independent risk factors for CALs,multivariable logistic regression models were constructed using significant variables identified from univariate logistic regression analysis.Results:The incidence of CALs was 36.0% (840 of 2331),including 625 (26.8%) coronary artery dilations and 215 (9.2%) coronary artery aneurysms (CAAs).Multivariable logistic regression analysis identified that male,incomplete KD,longer fever duration,and C-reactive protein (CRP) > 100 mg/L were independent risk factors for coronary artery dilatations.On the other hand,male,incomplete KD,longer fever duration,prolonged days of illness at the initial treatment,corticosteroid therapy,sodium ≤133 mmol/L,and albumin <35 g/L were the independent risk factors for CAAs.In addition,corticosteroid therapy,prolonged days of illness at the initial treatment,and albumin <35 g/L were the independent risk factors for giant CAAs.Conclusions:CALs might be associated with male sex,incomplete KD,longer fever duration,prolonged days of illness at the initial treatment,albumin <35 g/L,sodium ≤ 133 mmol/L,CRP > 100 mg/L,and corticosteroid therapy.Corticosteroid therapy was an independent risk factor for CAAs and giant CAAs.Thus,corticosteroids should be used with caution in the treatment of KD with the risk for CALs.

    Coronary artery inflammation and aneurysm formation are the most common complications of Kawasaki disease (KD). Valvulitis and myocarditis are also well described and may lead to valvar regurgitation and left ventricular dysfunction. However, functional changes in the right heart have rarely been reported. We noted several acute KD patients with dilated pulmonary arteries (PA) and thus sought to systematically characterize PA size and right-heart function in an unselected cohort of KD patients cared for at a single clinical center. Clinical, laboratory, and echocardiographic data from 143 acute KD subjects were analyzed. PA dilation was documented in 23 subjects (16.1 %); these subjects had higher median right ventricle myocardial performance index (RV MPI), higher ratio of early tricuspid inflow velocity to tricuspid annular early diastolic velocity (TV E/e'), and lower median TV e' velocity compared to the non-PA dilation group (0.50 vs 0.38 p < 0.01, 4.2 vs 3.6 p < 0.05, and 13.5 vs 15.2 cm/s p < 0.01, respectively). Almost all subjects with PA dilation had improved PA Z-score, RV MPI, and TV E/e' in the subacute phase (p < 0.01). There were no significant differences in indices of left ventricle function between PA dilation group and non-PA dilation group. In summary, PA dilation was documented in 16 % of acute KD subjects. These subjects were more likely to have echocardiographic indices consistent with isolated RV dysfunction that improved in the subacute phase. The long-term consequence of these findings will require longitudinal studies of this patient population. PMID:26681305

    Abstract Coronary artery (CA) abnormalities influence exercise capacity (EC) of patients with Kawasaki disease (KD), and Z-score of CA is a well established method for detecting CA aneurysm. We studied the influence of KD on cardiopulmonary function and EC; meanwhile we analyzed echocardiographic findings of KD patients. We also assessed the correlation between CA Z-score and EC of KD patients to see if CA Z-score of KD patients could reflect EC during exercise. Sixty-three KD patients were recruited as KD group 1 from children (aged 5–18 y) who received transthoracic echocardiographic examinations and symptom-limited treadmill exercise test for regular follow-up of KD from January 2010 to October 2014 in 1 medical center. We then divided KD group 1 into KD group 2 (pressure products (PRPPs) in KD group 1 to 3 were all lower than corresponding control groups significantly (P = 0.010, 0.020, and 0.049, respectively). PRPPs correlated with Max-Z of CA by both equations modest inversely (by Dallaire, P = 0.017, Spearman rho = −0.301; by Fuse, P = 0.014, Spearman rho = −0.309). Our study recruited larger number of KD patients and provided a newer data of EC of KD patients. Our finding suggests that after acute stage of KD, patients could maintain normal cardiorespiratory fitness. Therefore, we believe that it is important to promote cardiovascular health to KD patients and KD patients should exercise as normal peers. However, since KD patients might still have compromised coronary perfusion during exercise, it remains crucial to assess and monitor cardiovascular risk of KD patients. Max-Z of CA correlates with PRPP modest inversely and might be used as a follow-up indicator of CA reserve during exercise after acute stage of KD. PMID:26765431

    Background The epidemiologic pictures of Kawasaki disease (KD) in Shanghai from 1998 through 2002 were reported,while the current status of KD in the following five years remains unknown.Methods A questionnaire form and diagnostic guidelines for KD were sent to 50 hospitals providing pediatric medical care in Shanghai, China. All patients with KD diagnosed during January 2003 through December 2007 were recruited.Results In total, 1187 cases of KD were enrolled. The incidence of KD was 36.78 to 53.28 (mean 46.32±6.51) per 100 000children under the age of 5 years between 2003 and 2007, which was higher than the year from 1998 to 2002 of (27.32±7.11) per 100 000, (t=4.406, P=0.002). Ages at onset ranged from 12 days to 13.6 years (median 1.8 years). It occurred more frequently in summer and spring. Coronary arterial lesions (CAL), defined as ectasia or aneurysm,accounted for 19.8% (232 cases). Flattened or inverted T wave was the most frequent finding (194 cases, 20.5%) by electrocardiogram. Intravenous gamma-globulin was administrated to 1028 cases (86.6%). The occurrence of CAL seemed less frequent in the patients received gamma-globulin from day 5 to day 9 after the onset with the regimen of 1000 mg/kg once or 1000 mg/kg twice.Conclusions The incidence of KD was increasing in Shanghai. Treatment with intravenous gamma-globulin from day 5 to day 9 after the onset with the regimen of 1000 mg/kg once or 1000 mg/kg twice resulted in less coronary sequelae.

    Purpose Although a significant number of reports on new therapeutic options for refractory Kawasaki disease (KD) such as steroid, infliximab, or repeated intravenous immunoglobulin (IVIG) are available, their effectiveness in reducing the prevalence of coronary artery lesions (CAL) remains controversial. This study aimed to define the clinical characteristics of patients with refractory KD and to assess the effects of adjuvant therapy on patient outcomes. Methods We performed a retrospective study of 38 refractory KD patients from January 2012 to March 2015. We divided these patients into 2 groups: group 1 received more than 3 IVIG administration+ steroid therapy, (n=7, 18.4%), and group 2 patients were unresponsive to initial IVIG and required steroid therapy or second IVIG (n=31, 81.6%). We compared the clinical manifestations, laboratory results, and echocardiographic findings between the groups and examined the clinical utility of additional therapies in both groups. Results A significant difference was found in the total duration of fever between the groups (13.0±4.04 days in group 1 vs. 8.87±2.30 days in group 2; P=0.035). At the end of the follow-up, all cases in group 1 showed suppressed CAL. In group 2, coronary artery aneurysm occurred in 2 patients (6.4 %). All the patients treated with intravenous corticosteroids without additional IVIG developed CALs including coronary artery aneurysms. Conclusion No statistical difference was found in the development of CAL between the groups. Prospective, randomized, clinical studies are needed to elucidate the effects of adjunctive therapy in refractory KD patients. PMID:27610181

    Full Text Available Kawasaki disease (KD is an acute vasculitis in children that can cause coronary artery abnormalities. Its diagnosis is challenging, and many cytokines, chemokines, acute phase reactants, and growth factors have failed evaluation as specific biomarkers to distinguish KD from other febrile illnesses. We performed protein profiling, comparing plasma from children with KD with febrile control (FC subjects to determine if there were specific proteins or peptides that could distinguish the two clinical states.Plasma from three independent cohorts from the blood of 68 KD and 61 FC subjects was fractionated by anion exchange chromatography, followed by surface-enhanced laser desorption ionization (SELDI mass spectrometry of the fractions. The mass spectra of KD and FC plasma samples were analyzed for peaks that were statistically significantly different.A mass spectrometry peak with a mass of 7,860 Da had high intensity in acute KD subjects compared to subacute KD (p = 0.0003 and FC (p = 7.9 x 10-10 subjects. We identified this peak as a novel truncated form of serum amyloid A with N-terminal at Lys-34 of the circulating form and validated its identity using a hybrid mass spectrum immunoassay technique. The truncated form of serum amyloid A was present in plasma of KD subjects when blood was collected in tubes containing protease inhibitors. This peak disappeared when the patients were examined after their symptoms resolved. Intensities of this peptide did not correlate with KD-associated laboratory values or with other mass spectrum peaks from the plasma of these KD subjects.Using SELDI mass spectrometry, we have discovered a novel truncated form of serum amyloid A that is elevated in the plasma of KD when compared with FC subjects. Future studies will evaluate its relevance as a diagnostic biomarker and its potential role in the pathophysiology of KD.

    In this study we aimed to screen genes associated with intravenous immunoglobulin (IVIG) responding in patients with Kawasaki disease (KD) and thus explore the underlying molecular mechanism of IVIG resistance. The differentially expressed genes (DEGs) were identified by samr package in R. Then, protein-protein interaction (PPI) networks were constructed by STRING software. We further collected the regulatory data from TRANSFAC database, followed by regulatory interaction network construction. A total 194 of DEGs, including 185 up- and 9 down-regulated DEGs, were identified between IVIG-responding and non-responding patients with KD at acute stage. In contrast, no DEGs were found at convalescent stage. PPI networks and regulatory networks were constructed based on the 185 up-regulated genes at acute stage. The degrees of TFRC (transferrin receptor protein 1) and GADD45A (growth arrest and DNA-damage-inducible alpha) were higher than other genes, and meanwhile MYC (V-Myc Myelocytomatosis Viral Oncogene Homolog) and E2F1 (E2F Transcription Factor 1) were found to be two TFs (transcription factors) with the highest degrees. In conclusions, the response to IVIG in Kawasaki disease patients may be involved in the expression of TFRC, GADD45A, MYC and E2F1. PMID:25449331

    Kawasaki disease (KD) or Kawasaki syndrome is known as a vasculitis of small to medium-sized vessels, and coronary arteries are predominantly involved in childhood. Generally, 20–25% of untreated with IVIG and 3–5% of treated KD patients have been developed coronary artery lesions (CALs), such as dilatation and aneurysm. Understanding how coronary artery aneurysms (CAAs) are established and maintained in KD patients is therefore of great importance. Upon our previous genotyping data of 157 valid KD subjects, a genome-wide association study (GWAS) has been conducted among 11 (7%) CAA-developed KD patients to reveal five significant genetic variants passed pre-defined thresholds and resulted in two novel susceptibility protein-coding genes, which are NEBL (rs16921209 (P = 7.44 × 10−9; OR = 32.22) and rs7922552 (P = 8.43 × 10−9; OR = 32.0)) and TUBA3C (rs17076896 (P = 8.04 × 10−9; OR = 21.03)). Their known functions have been reported to associate with cardiac muscle and tubulin, respectively. As a result, this might imply their putative roles of establishing CAAs during KD progression. Additionally, various model analyses have been utilized to determine dominant and recessive inheritance patterns of identified susceptibility mutations. Finally, all susceptibility genes hit by significant genetic variants were further investigated and the top three representative gene-ontology (GO) clusters were regulation of cell projection organization, neuron recognition, and peptidyl-threonine phosphorylation. Our results help to depict the potential routes of the pathogenesis of CAAs in KD patients and will facilitate researchers to improve the diagnosis and prognosis of KD in personalized medicine.

    Full Text Available Introduction. Cat scratch disease (CSD is an acute infectious disease with benign course caused by the bacteria Bartonella henselae. Clinically, it is usually manifested as regional lymphadenopathy and mild infective syndrome. Rare forms of the disease which usually occur in immunocompromised presons are: encephalitis, transverse myelitis, neuroretinitis, granulomatosus conjunctivitis, arthritis, hepatitis etc. Case report. We presented an atypical form of cat scratch disease in a young immunocompetent female person. The disease was manifested with prolonged fever, rash, purulent lymphadenitis and hepatitis. The diagnosis was based on characteristic patohystological finding and exclusion of the other causes of lymphadenopathy. The patient was treated by antibiotics for a few weeks, with surgical incision and drainage of the purulent lymphadenitis. Conclusion. Atypical forms of CSD could be an important differential-diagnostic problem, especially if there is no opportunity for serological confirmation of the disease.

  13. Assessment of coronary artery aneurysms in paediatric patients with Kawasaki disease by multidetector row CT angiography: feasibility and comparison with 2D echocardiography

    International Nuclear Information System (INIS)

    Transthoracic ECHO is the locally accepted method for coronary surveillance of patients with Kawasaki disease but it may have limited visualization in the older child. To assess the feasibility of multidetector CT (MDCT) angiography in the follow-up of coronary artery aneurysms in children with previous Kawasaki disease. Six children (5 boys, 1 girl; mean age 11.5 years) with known Kawasaki disease and coronary artery involvement underwent CT coronary angiography using 16-detector MDCT. The visualized lengths and diameter of all coronary segments were measured. The number, size and location of coronary artery aneurysms were recorded and compared with recent ECHO. Twelve coronary artery aneurysms (seven saccular, five fusiform) were identified by MDCT angiography. One saccular aneurysm at the junction of the distal right coronary artery and posterior descending artery was not detected by ECHO while the remaining six in proximal segments were detected by both modalities. Two of five fusiform aneurysms were not detected by ECHO due to their small sizes. Excellent agreement was found between CT and ECHO for maximal diameter and length of the visualized aneurysms. MDCT angiography accurately defines coronary artery aneurysms. It is more sensitive for detecting aneurysms at distal coronary segments and fusiform aneurysms of small size

    Kawasaki disease (KD) is a leading cause of acquired heart disease predominantly affecting infants and young children. Intravenous immunoglobulin (IVIG) is applied as the most favorable treatment against KD, but IVIG resistant remains exist. Although several clinical scoring systems have been developed to identify children at highest risk of IVIG resistance, there is a need to identify sufficiently sensitive biomarkers for IVIG treatment. Some differentially expressed genes (DEGs) could be the promising potential biomarkers for IVIG-related sensitivity diagnosis. We employed a systematic and integrative bioinformatics framework to identify such kind of genes. The performance of the candidate genes was evaluated by hierarchical clustering, ROC analysis and literature mining. By analyzing three datasets of KD patients, 34 DEGs of the three groups have been found to be associated with IVIG-related sensitivity. A module of 12 genes could predict resistant group patients with high accuracy, and a module of ten genes could predict responsive group patients effectively with accuracy of 96 %. And three of them are most likely to serve as drug targets or diagnostic biomarkers in the future. Compared with unsupervised hierarchical clustering analysis, our modules could distinct IVIG-resistant patients efficiently. Two groups of DEGs could predict IVIG-related sensitivity with high accuracy, which are potential biomarkers for the clinical diagnosis and prediction of IVIG treatment response in KD patients, improving the prognosis of patients.

    Full Text Available Kawasaki disease (KD is an acute febrile systemic vasculitis and has been reported to be associated with allergic disease. The risk of atopic dermatitis (AD in preschool children with KD has not been investigated. The study was to determine the longitudinal risk of the development of AD in preschool children with KD. A nationwide 5-year population-based study was performed using data from the National Health Insurance Database in Taiwan between 1999 and 2003. The risk factors for AD were compared between the 2 study groups during the follow-up period using the Cox proportional hazards model. In addition, plasma interleukin (IL-5 levels were analyzed in normal subjects and KD patients. Among the 1440 subjects included, 21.6% developed AD during the 5-year follow-up period, of which 30.3% and 18.7% belonged to the study cohort and the comparison group, respectively. Children with KD were 1.25 times more likely to have AD than those in controls (P=0.04. Levels of IL-5 and IgE were significantly higher in KD patients. Children with KD had a higher risk of developing AD during the 5-year follow-up period than the control group. Increased IL-5 and IgE levels may be key factors contributing to the risk of AD.

    Twenty-five-hydroxyvitamin D (25(OH)-vitamin D) is crucial in the regulation of immunologic processes, but-although its deficiency has been reported in patients with different rheumatological disorders-no data are available for Kawasaki disease (KD). The goals of this study were to assess the serum levels of 25(OH)-vitamin D in children with KD and evaluate the relationship with the eventual occurrence of KD-related vascular abnormalities. We evaluated serum 25(OH)-vitamin D levels in 79 children with KD (21 females, 58 males, median age 4.9 years, range 1.4-7.5 years) in comparison with healthy sex-/age-matched controls. A significantly higher percentage of KD patients (98.7 %) were shown to have reduced 25(OH)-vitamin D levels (vitamin D than controls (9.17 ± 4.94 vs 23.3 ± 10.6 ng/mL, p vitamin D levels correlated not only with erythrosedimentation rate (p vitamin D might have a contributive role in the development of coronary artery complications observed in children with KD.

    Full Text Available Coronary arteritis, a complication of Kawasaki disease (KD, can be refractory to immunoglobulin (IVIG treatment. To determine the most effective alternative therapy, we compared the efficacy of different agents in a mouse model of KD. Vasculitis was induced by injection of Candida albicans water-soluble fractions (CAWS into a DBA/2 mouse, followed by administration of IVIG, etanercept, methylprednisolone (MP, and cyclosporine-A (CsA. At 2 and 4 weeks, the mice were sacrificed, and plasma cytokines and chemokines were measured. CAWS injection induced active inflammation in the aortic root and coronary arteries. At 2 weeks, the vasculitis was reduced only by etanercept, and this effect persisted for the subsequent 2 weeks. At 4 weeks, IVIG and CsA also attenuated the inflammation, but the effect of etanercept was more significant. MP exerted no apparent effect at 2 or 4 weeks. The suppressive effect exerted by etanercept on cytokines, such as interleukin- (IL-6, IL-12, IL-13, and tumor necrosis factor-α (TNF-α, was more evident than that of others. The extent of arteritis correlated with the plasma TNF-α levels, suggesting a pivotal role of TNF-α in KD. In conclusion, etanercept was most effective in suppressing CAWS-induced vasculitis and can be a new therapeutic intervention for KD.

    Full Text Available Kawasaki disease (KD is a multi-systemic vasculitis that preferentially affects children. A single nucleotide polymorphism (SNP in inositol 1,4,5-trisphosphate 3-kinase C (ITPKC has been identified to be an important polymorphism in the risk of KD. This study was conducted to comprehensively investigate the associations between all tagging SNPs of ITPKC in the risk of KD in a Taiwanese population. A total of 950 subjects (381 KD patients and 569 controls were recruited. Seven tagging SNPs (rs11673492, rs7257602, rs7251246, rs890934, rs10420685, rs2607420, rs2290692 were selected for TaqMan allelic discrimination assay. Clinical data of coronary artery lesions (CAL and aneurysms were collected for analysis. A significant association was found between rs7251246 in ITPKC and CAL formation. Haplotype analysis for ITPKC polymorphisms also confirmed this association in the patients with CAL and aneurysm formation. This is the first study to identify that SNP rs7251246 in ITPKC is associated with the severity of KD.

    Full Text Available We describe a case of papillated Bowen disease (PBD, associated with a clear cell atypical fibroxanthoma (CCAFXA. The epidermal lesion showed a bowenoid papillomatous growth pattern with histologic features suggestive of infection by human papilloma virus (HPV. In the dermis a neoplasm made up by spindled or polygonal cells with wide clear cytoplasm and moderate nuclear pleomorphism was found. Immunohistochemical characteristics of these two lesions were clearly different. The atypical cells of the intraepidermal proliferation were positive for AE1-AE3 anticytokeratin antibody, EMA, p16, p53 and p63. The dermal tumor was positive for vimentin, CD10, CD68, CD99, alpha-1-antitrypsin and c-kit. Histological features and immunohistochemical profile of the dermal tumor corresponded to a CCAFXA, a very uncommon neoplasm of which only 10 cases have been reported. In situ hybridization for numerous types of HPVs was negative in both lesions.

    The feasibility of coronary function estimation by single photon emission computed tomography (SPECT) has been recently demonstrated. The aim of this study was to apply SPECT imaging in patients with previous Kawasaki disease (KD) to assess the coronary functional status at long-term follow-up of the acute phase of the disease. Sixteen children with a history of KD underwent {sup 99m}Tc-sestamibi imaging at rest and during the cold pressor test (CPT). Myocardial blood flow (MBF) was estimated by measuring first transit counts in the pulmonary artery and myocardial counts from SPECT images. Coronary endothelial function was expressed as the ratio of the CPT to rest MBF. Six KD patients without coronary artery lesions served as controls and ten with coronary artery aneurysms during the acute phase of the disease were separated into two groups: group 1 (n = 4) with regressed and group 2 (n = 6) with persistent aneurysm at follow-up. The estimated coronary endothelial function was higher in controls compared to patients with coronary artery aneurysms (2.5 {+-} 0.3 vs 1.7 {+-} 0.7, p < 0.05). A significant difference in coronary endothelial function among groups was found (F = 5.21, p < 0.02). Coronary endothelial function was higher in patients of group 1 than in those of group 2 (1.9 {+-} 0.6 vs 1.4 {+-} 0.7, p < 0.02). SPECT may be applied as a noninvasive method for assessing coronary vascular function in children with a history of KD, demonstrating an impaired response to the CPT, an endothelial-dependent vasodilator stimulus. These findings reinforce the concept that coronary endothelial dysfunction may represent a long-term sequela of KD. (orig.)

    Full Text Available Kawasaki disease (KD is an acute systemic vasculitis syndrome that primarily affects infants and young children. Its etiology is unknown; however, epidemiological findings suggest that genetic predisposition underlies disease susceptibility. Taiwan has the third-highest incidence of KD in the world, after Japan and Korea. To investigate novel mechanisms that might predispose individuals to KD, we conducted a genome-wide association study (GWAS in 250 KD patients and 446 controls in a Han Chinese population residing in Taiwan, and further validated our findings in an independent Han Chinese cohort of 208 cases and 366 controls. The most strongly associated single-nucleotide polymorphisms (SNPs detected in the joint analysis corresponded to three novel loci. Among these KD-associated SNPs three were close to the COPB2 (coatomer protein complex beta-2 subunit gene: rs1873668 (p = 9.52×10⁻⁵, rs4243399 (p = 9.93×10⁻⁵, and rs16849083 (p = 9.93×10⁻⁵. We also identified a SNP in the intronic region of the ERAP1 (endoplasmic reticulum amino peptidase 1 gene (rs149481, p(best = 4.61×10⁻⁵. Six SNPs (rs17113284, rs8005468, rs10129255, rs2007467, rs10150241, and rs12590667 clustered in an area containing immunoglobulin heavy chain variable regions genes, with p(best-values between 2.08×10⁻⁵ and 8.93×10⁻⁶, were also identified. This is the first KD GWAS performed in a Han Chinese population. The novel KD candidates we identified have been implicated in T cell receptor signaling, regulation of proinflammatory cytokines, as well as antibody-mediated immune responses. These findings may lead to a better understanding of the underlying molecular pathogenesis of KD.

    Full Text Available Purpose : Kawasaki disease (KD is a systemic vasculitis, a leading cause of pediatric acquired heart disease. Histopathological findings of coronary artery lesion (CAL in KD indicate destruction of the coronary artery wall with diffuse vasculitis. Matrix metalloproteinases (MMPs and their endogenous tissue inhibitors (TIMPs might play central roles in this process. Special attention to MMP-9 has recently been emerging. This study was performed to investigate the clinical significance of MMP-9 and its inhibitors, TIMP-1 and TIMP-2, in KD. Methods : We compared 47 KD patients with 14 febrile controls. Serum MMP-9 and TIMP-1, TIMP-2 were measured by ELISA and compared according to clinical stages and coronary involvement. Results : In acute stage, MMP-9 and TIMP-1 were significantly higher, whereas TIMP-2 was lower, in KD than those in febrile controls (P &lt;0.05. The elevated MMP-9 levels in acute phase significantly decreased during the subacute and convalescent phases (P &lt;0.05. During acute phase, the MMP-9, TIMP-1, and MMP-9/TIMP-2 levels in the CAL group were lower than those in the non-CAL group, but they increased significantly in the subacute phase (P &lt;0.05. MMP-9 has a positive correlation with TIMP-1 in the acute and subacute phases, and negative correlation with TIMP-2 in the subacute and convalescent phases (P &lt;0.05. Conclusion : These results suggest that MMP-9, TIMP-1, and the imbalance in MMP-9 and TIMP-2 might play important roles on the pathophysiology of KD and especially on the development of CAL. However, further larger studies are needed.

    Full Text Available Kawasaki disease (KD is pediatric systemic vasculitis with the classic complication of coronary artery aneurysm (CAA. It is the leading cause of acquired cardiovascular diseases in children. Some severe cases present with multi-organ involvement or neurological dysfunction. To identify the role of the glutamate receptor, ionotropic, N-methyl-d-aspartate 3A (GRIN3A in KD, we investigated genetic variations in GRIN3A in a Taiwanese cohort of 262 KD patients (76 with and 186 without CAA complications. We used univariate and multivariate regression analyses to identify the associations between clinical characteristics and GRIN3A genetic variations in KD. According to univariate regression analysis, CAA formation in KD was significantly associated with fever duration (p < 0.0001, first Intravenous immunoglobulin (IVIG used (days after day one of fever (p < 0.0001, and the GRIN3A (rs7849782 genetic variant (p < 0.001. KD patients with GG+GC genotype showed a lower rate of developing CAA (GG+GC genotype: odds ratio = 0.26; 95% CI = 0.14-0.46. Significant associations were identified between KD with CAA complication and the GRIN3A (rs7849782 genetic variant by using multivariate regression analysis. Specifically, significant correlations were observed between KD with CAA complications and the presence of GG+GC genotypes for the GRIN3A rs7849782 single-nucleotide polymorphism (full model: odds ratio = 0.25; 95% CI = 0.14-0.46. Our results suggest that a polymorphism of the GRIN3A gene may play a role in KD pathogenesis.

  5. A simple method for assessment of human anti-Neu5Gc antibodies applied to Kawasaki disease.

    Directory of Open Access Journals (Sweden)

    Vered Padler-Karavani

    Full Text Available N-glycolylneuraminic acid (Neu5Gc is an immunogenic sugar of dietary origin that metabolically incorporates into diverse native glycoconjugates in humans. Anti-Neu5Gc antibodies are detected in all human sera, though with variable levels and epitope-recognition profiles. These antibodies likely play a role in several inflammation-mediated pathologies including cardiovascular diseases and cancer. In cancer, they have dualistic and opposing roles, either stimulating or repressing disease, as a function of their dose, and some of these antibodies serve as carcinoma biomarkers. Thus, anti-Neu5Gc antibodies may signify risk of inflammation-mediated diseases, and changes in their levels could potentially be used to monitor disease progression and/or response to therapy. Currently, it is difficult to determine levels of anti-Neu5Gc antibodies in individual human samples because these antibodies recognize multiple Neu5Gc-epitopes. Here we describe a simple and specific method for detection and overall estimation of human anti-Neu5Gc antibodies. We exploit the difference between two mouse models that differ only by Neu5Gc-presence (wild-type or Neu5Gc-absence (Cmah(-/- knockout. We characterize mouse serum from both strains by HPLC, lectin and mass-spectrometry analysis and show the target Neu5Gc-epitopes. We then use Cmah(-/- knockout sera to inhibit all non-Neu5Gc-reactivity followed by binding to wild-type sera to detect overall anti-Neu5Gc response in a single assay. We applied this methodology to characterize and quantify anti-Neu5Gc IgG and IgA in sera of patients with Kawasaki disease (KD at various stages compared to controls. KD is an acute childhood febrile disease characterized by inflammation of coronary arteries that untreated may lead to coronary artery aneurysms with risk of thrombosis and myocardial infarction. This estimated response is comparable to the average of detailed anti-Neu5Gc IgG profile analyzed by a sialoglycan microarray

    Background and Objectives In Kawasaki disease (KD), high dose intravenous immunoglobulin (IVIG) significantly lowers the coronary complications. However, some patients either do not respond to initial therapy or develop coronary complications. We aimed to identify the predictive factors for unresponsiveness to initial IVIG therapy and coronary artery dilatation (CAD; defined by Z-score≥2.5) in the acute phase and convalescent phase. Subjects and Methods A retrospective review was conducted of 703 patients with KD, admitted to Gachon University Gil Medical Center between January 2005 and June 2013. The patients were divided into two groups—IVIG responders vs. non-responders—based on the IVIG treatments, and presence of fever after treatment. Further, these groups were divided into two subgroups based on their CAD. Results Among the 703 patients with KD, the rate of non-responders to initial IVIG was 16.8%. Serum total bilirubin, platelet count, and neutrophil proportion were independent predictive parameters of unresponsiveness (p<0.05). CAD was found in 234 patients (33.3%) in the acute phase, and in 32 patients (4.6%) in the convalescent phase. Male gender, fever duration, serum C-reactive protein, and white blood cell count were related to CAD (p<0.05). CAD was detected more frequently in non-responders than in the responders (47.5% vs. 31.5%, p=0.001). Kobayashi, Egami, and Sano scoring systems applied to our study population reflected low sensitivities (28.0-33.9%). Conclusion Several independent parameters were related to unresponsiveness to the initial IVIG or CAD. These parameters might be helpful in establishing more focused and careful monitoring of high-risk KD patients in Korea.

    Background: Ongoing low-grade inflammation and endothelial dysfunction persist in children with coronary lesions diagnosed with Kawasaki disease (KD). Statins, frequently used in the management of high cholesterol, have also shown to improve surrogate markers of infl ammation and endothelial dysfunction. This study was undertaken to investigate the effi cacy and safety of pravastatin in children with coronary artery aneurysms due to KD. Methods: The study enrolled 14 healthy children and 13 male children, aged 2-10 years, with medium-to-giant coronary aneurysms for at least 12 months after the onset of KD. Pravastatin was given orally to the KD group at a dose of 5 mg/day for children under 5 and 10 mg/day for children older than 5 years. To determine the effects of pravastatin on endothelial function, high-frequency ultrasound was performed before the start of the study and 6 months after pravastatin therapy. The parameters measured were brachial artery flow-mediated dilation (FMD), non-flow mediated dilation (NMD), and carotid artery stiffness index (SI). High sensitive C-reactive protein (hs-CRP) levels, the circulating endothelial progenitor cells (EPCs) number, and serum lipid profiles were also determined at baseline and after 6 months of pravastatin treatment. Results: Before treatment, the KD group had significantly decreased FMD (P0.05). No signifi cant complications were noted with paravastatin therapy. Conclusions: Pravastatin improves endothelial function and reduces low-grade chronic infl ammation in patients with coronary aneurysms due to KD. Children with coronary aneurysms due to KD may benefit from statin therapy.

    Background Coronary artery damage from Kawasaki disease (KD) is closely linked to the dysfunction of the endothelial progenitor cells (EPCs).The aim of the present study was to evaluate the modulatory effect of granulocyte colony stimulating factor (G-CSF) on EPCs and elastin breakdown of coronary arteries in a KD mouse model.Methods A Lactobacillus casei cell wall extract (LCWE)-induced KD model was established in C57BL/6 mice that were subsequently administrated with recombinant human G-CSF (rhG-CSF).Nω-nitro-L-arginine methyl ester (L-NAME) was administrated for the negative intervention.Evaluations included coronary artery lesions,EPC number and functions,and the plasma concentration of nitric oxide (NO).Results Elastin breakdown was found in the coronary arteries of model mice 56 days after injection of LCWE.The number of circulating EPCs,plasma concentration of NO,and functions of bone marrow EPCs,including proliferation,adhesion,and migration abilities,were all lower in the KD model group compared with those in the control group.After administration of rhG-CSF,the number of circulating EPCs and plasma concentration of NO were increased significantly compared with those in the KD model group.There were also increases in the functional indexes of EPCs.Furthermore,rhG-CSF administration improved the elastin breakdown effectively.However,these protective effects of rhG-CSF on coronary arteries were attenuated by L-NAME.Conclusion The present study indicated that the administration of G-CSF prevents elastin breakdown of the coronary arteries by enhancing the number and functions of EPCs via the NO system,and then accelerates the repair of coronary artery lesions in the KD.

    Objective The present study was designed to analyse the clinical features of intravenous immunoglobulin-resistant Kawasaki disease in children. Method A retrospective analysis of 102 hospitalized children with Kawasaki disease was conducted. Result Compared with those of intravenous immunoglobulin responders of Kawasaki disease cases, children with intravenous immunoglobulin-resistant Kawasaki disease had a prolonged duration of fever, and increased morbidity of coronary artery lesions and ST-T abnormalities in ECG. ST-T abnormalities in ECG before treatment and prolonged duration of fever are risks for intravenous immunoglobulin-resistant Kawasaki disease. Conclusions Children with intravenous immunoglobulin-resistant Kawasaki disease had a longer duration of fever and an increased rate of abnormal ST-T changes in ECG. Children having a longer duration of fever and abnormal ST-T have an increased possibility to have intravenous immunoglobulin-resistant Kawasaki disease.%目的 分析静脉注射丙种球蛋白(IVIG)无反应型川崎病患儿的临床特点及危险因素,并探讨其治疗及预后.方法 对住院治疗的102例川崎病患儿病例进行回顾性分析.结果 与反应组相比,无反应组患儿总发热天数明显延长,冠状动脉病变、心电图ST-T段改变的发生率明显升高.治疗前ST-T段改变和发热天数较长是发生IVIG无反应的危险因素.结论 IVIG无反应型川崎病较IVIG反应型川崎病发热时间延长,更易发生冠状动脉病变及心电图ST-T段改变.治疗前ST-T段改变和发热天数较长的患儿发生IVIG无反应的可能性更高.

  12. Treatment response in Kawasaki disease is associated with sialylation levels of endogenous but not therapeutic intravenous immunoglobulin G.

    Full Text Available OBJECTIVES: Although intravenous immunoglobulin (IVIG is highly effective in Kawasaki disease (KD, mechanisms are not understood and 10-20% of patients are treatment-resistant, manifesting a higher rate of coronary artery aneurysms. Murine models suggest that α2-6-linked sialic acid (α2-6Sia content of IVIG is critical for suppressing inflammation. However, pro-inflammatory states also up-regulate endogenous levels of β-galactoside:α2-6 sialyltransferase-I (ST6Gal-I, the enzyme that catalyzes addition of α2-6Sias to N-glycans. We asked whether IVIG failures correlated with levels of α2-6Sia on infused IVIG or on the patient's own endogenous IgG. METHODS: We quantified levels of α2-6Sia in infused IVIG and endogenous IgG from 10 IVIG-responsive and 10 resistant KD subjects using multiple approaches. Transcript levels of ST6GAL1, in patient whole blood and B cell lines were evaluated by RT-PCR. Plasma soluble (sST6Gal-I levels were measured by ELISA. RESULTS: There was no consistent difference in median sialylation levels of infused IVIG between groups. However, α2-6Sia levels in endogenous IgG, ST6GAL1 transcript levels, and ST6Gal-I protein in serum from IVIG-resistant KD subjects were lower than in responsive subjects at both pre-treatment and one-year time points (p <0.001, respectively. CONCLUSIONS: Our data indicate sialylation levels of therapeutic IVIG are unrelated to treatment response in KD. Rather, lower sialylation of endogenous IgG and lower blood levels of ST6GALI mRNA and ST6Gal-I enzyme predict therapy resistance. These differences were stable over time, suggesting a genetic basis. Because IVIG-resistance increases risk of coronary artery aneurysms, our findings have important implications for the identification and treatment of such individuals.

    Full Text Available Kawasaki disease (KD is a systemic vasculitis of unknown etiology. The innate immune system is involved in its pathophysiology at the acute phase. We have recently established a novel murine model of KD coronary arteritis by oral administration of a synthetic microbe-associated molecular pattern (MAMP. On the hypothesis that specific MAMPs exist in KD sera, we have searched them to identify KD-specific molecules and to assess the pathogenesis.We performed liquid chromatography-mass spectrometry (LC-MS analysis of fractionated serum samples from 117 patients with KD and 106 controls. Microbiological and LC-MS evaluation of biofilm samples were also performed.KD samples elicited proinflammatory cytokine responses from human coronary artery endothelial cells (HCAECs. By LC-MS analysis of KD serum samples collected at 3 different periods, we detected a variety of KD-specific molecules in the lipophilic fractions that showed distinct m/z and MS/MS fragmentation patterns in each cluster. Serum KD-specific molecules showed m/z and MS/MS fragmentation patterns almost identical to those of MAMPs obtained from the biofilms formed in vitro (common MAMPs from Bacillus cereus, Yersinia pseudotuberculosis and Staphylococcus aureus at the 1st study period, and from the biofilms formed in vivo (common MAMPs from Bacillus cereus, Bacillus subtilis/Bacillus cereus/Yersinia pseudotuberculosis and Staphylococcus aureus at the 2nd and 3rd periods. The biofilm extracts from Bacillus cereus, Bacillus subtilis, Yersinia pseudotuberculosis and Staphylococcus aureus also induced proinflammatory cytokines by HCAECs. By the experiments with IgG affinity chromatography, some of these serum KD-specific molecules bound to IgG.We herein conclude that serum KD-specific molecules were mostly derived from biofilms and possessed molecular structures common to MAMPs from Bacillus cereus, Bacillus subtilis, Yersinia pseudotuberculosis and Staphylococcus aureus. Discovery of these KD

  14. Usefulness of 64-slice MDCT for follow-up of young children with coronary artery aneurysm due to Kawasaki disease: Initial experience

    International Nuclear Information System (INIS)

    To evaluate the initial application and value of 64-slice multidetector computed tomography as an alternative diagnostic modality in the follow-up of young children with coronary artery aneurysm due to Kawasaki disease. Twelve boys (mean age 5.1 years, range 1.8-7.8 years) for follow-up (time range from 1.1 to 5.1 years) of known Kawasaki disease and coronary artery aneurysm underwent 64-slice MDCT ECG-gated coronary angiography. All data were acquired without breath holding. Two pediatric radiologists independently assessed image quality and the diameter of all coronary segments were measured for each patient. The number, position, shape and size of each coronary artery aneurysm were observed and compared with those of ECHO performed previously. A total of 118/156 segments permitted visualization with diagnostic image quality, the CT measurements showed good inter-observer and intra-observer reliability, coefficients were 0.93 and 0.88, respectively. A total of 30 coronary artery aneurysms were identified with measured mean of 7.5 ± 3.8 mm in diameter, and of 12.4 ± 9.1 mm in longitudinal lengths.10 tumors were small, 8 tumors were medium and 12 tumors were giant aneurysm. The affected segments included LM7/12(58.3%), 9/12(75%) of LAD1, 4/12(33.3%) of LAD2, 2/12(16.7%) of LCX1; 6/12(50%) of RCA1, 9/12(75%) of RCA2 and 4/12(33.3%) of RCA3, including affected two segments in 9 tumors and three segments in 1 tumor. Calcifications were found in 5 aneurysms and 3/5 with thrombosis; six stenotic segments were found. ECHO failed to detect 8 tumors with 2/8 in LAD, 1/8 in LCX and 5/8 in RCA, and those included 4 small aneurysms. The use of 64-slice MDCT angiography proved valuable for monitoring young children with Kawasaki disease. However, further study is necessary to specify the sensitivity and specificity of MDCT in the follow-up.

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

    Kawasaki disease (KD) is an acute systemic vasculitis and its main life-threatening complications are coronary artery lesions(CAL), including coronary artery stenosis, thrombosis, aneurysm rupture, or sudden death. KD has now surpassed acute rheumatic fever as the leading cause of acquired heart disease in children. Therefore, it is important to identify as early as possible KD patients who are at risk for the development of CAL and intervent them timely. Genetic factors are thought to have important influences on the development and progress of Kawasaki disease and its CAL. In previous reports, several genetic polymorphisms, such as VEGF, MMPs and CD14 gene, were associated with the development of CAL. This review will introduce the study of gene polymorphisms in susceptibility to CAL in children with KD recently.%川崎病(KD)主要危及生命的并发症是冠状动脉损害(CAL),引起冠状动脉狭窄、血栓形成、动脉瘤破裂等,甚至猝死.KD现已成为儿童后天性心脏病的主要病因.因此,早期发现哪些KD患儿是发生CAL的易患人群,并予及时干预十分重要.遗传因素在KD及其CAL的发生发展中起重要作用,目前已发现多个基因的多态性与CAL相关.该文主要就近年来国内外关于KD合并CAL基因多态性的研究作一综述.

    Standard treatment of acute Kawasaki disease involves giving 2 grams per kilogram of immunoglobulin intravenously along with aspirin. More than half of the patients with acute Kawasaki disease, nonetheless, can be cured by giving only 1 gram per kilogram of immunoglobulin, thus reducing this aspect of the cost of treatment by half. Our purpose was to predict those patients with acute Kawasaki disease who would respond to treatment with 1 gram per kilogram of immunoglobulin given intravenously on the basis of their clinical profiles and laboratory findings prior to the initial treatment. We performed a retrospective review of the clinical records of consecutive patients with acute Kawasaki disease treated in our hospital with intravenous immunoglobulin from January, 2001, to December, 2005.During this period, we treated in this fashion 98 patients with acute Kawasaki disease. 65% of these needing immunoglobulin therapy were cured by giving 1 gram per kilogram. The neutrophil count and the percentage of white blood cells representing neutrophils, along with aspirate aminotransferase, alanine aminotransferase, bilirubin and C reactive protein, were all significantly lower, and sodium was significantly higher, in those responding to 1 gram per kilogram of immunoglobulin when compared to those who did not respond. The days of illness at the first intravenous treatment was later in those responding than in those failing to respond. We generated a score for prediction, assigning a point for each of C reactive protein equal to or greater than 10 mg/dl, sodium equal to or lower than 133 meq/l, alanine aminotransferase equal to or greater than 110 IU/l, and 2 points for the percentage of white blood cells representing neutrophils equal to or greater than 70%. Using a cut-off point of a score less than 2, we were able to identify those responding with 60% sensitivity, and 91% specificity.Thus, we are now able to predict those patients with acute Kawasaki disease who will

    Objective: To explore the relationship between severe infection and prognosis of Kawasaki disease. Methods; A total of 271 children with Kawasaki disease who were diagnosed and treated in pediatric department of the hospital and got fever within seven days from May 2005 to May 2010 were selected, and all the children conformed to the diagnostic criteria revised on the Third International Kawasaki Disease Symposium. All the children were divided into severe infection group (73 children) and non - severe infection group ( 198 children) according to the score of children with critical illness ( preliminary draft) . Forty - four children with severe pneumonia ( including 17 children with serum Mycoplasma pneumoniae IgM titer^l: 160) , 20 children with viral encephalitis, and 9 children with sepsis were included into severe infection group. Results; There was significant difference in the number of children under one year old between severe infection group and non - severe infection group (P 0. 05) . The numbers of children with platelet 60 mm/h, and C - reactive protein >45 mg/L in severe infection group were significantly higher than those in non -severe infection group (P 0. 05 ) . After treating the children with gamma globulin for 36 hours, the number of children with pyretolysis in severe infection group was less than that in non - severe infection group (x2 = 13. 155, P 0. 05) ; the number of children with coronary arteriectasis within six months in severe infection group was significantly higher than that in non - severe infection group (x2 = 4. 595 , P < 0. 05) . Conclusion; The children with severe infection have high probability of coronary artery lesions, which indicates that severe infection can be used as an early indicator of poor prognosis of Kawasaki disease. The reaction of children with Kawasaki disease combined with severe infection to gamma globulin therapy is poor, and the children are prone to combine with coronary arteriectasis. Thus, the

    Kimura's disease is a rare chronic inflammatory disorder predominantly affecting young Asian male patients, occurring mainly in the head and neck regions. Kimura's disease of the upper extremity is extremely rare, and previous case reports in the literature show similar imaging characteristics with consistent location at the medial epitrochlear region, predominantly with unilateral involvement. We present the first reported case of Kimura's disease affecting the anterolateral aspect of the upper arm, sparing the medial epitrochlear region, illustrating that with typical MR appearance and serology, the involvement of this rare disease in an atypical location still warrants consideration of this diagnosis. There was also bilateral asymmetrical involvement in our patient, suggesting the possibility of a propensity for Kimura's disease affecting the upper extremities to have bilateral involvement, which may necessitate imaging of the clinically asymptomatic contralateral limb in these patients for early lesion identification and treatment.

    Public and animal health controls to limit human exposure to animal prions are focused on bovine spongiform encephalopathy (BSE), but other prion strains in ruminants may also have zoonotic potential. One example is atypical/Nor98 scrapie, which evaded statutory diagnostic methods worldwide until the early 2000s. To investigate whether sheep infected with scrapie prions could be another source of infection, we inoculated transgenic mice that overexpressed human prion protein with brain tissue from sheep with natural field cases of classical and atypical scrapie, sheep with experimental BSE, and cattle with BSE. We found that these mice were susceptible to BSE prions, but disease did not develop after prolonged postinoculation periods when mice were inoculated with classical or atypical scrapie prions. These data are consistent with the conclusion that prion disease is less likely to develop in humans after exposure to naturally occurring prions of sheep than after exposure to epizootic BSE prions of ruminants.

    In clinics,pediatric fever is commonly encountered characterized with a variety of causes, complex condition and rapid changes. This article reported the diagnosis and treatment of a child with typical kawasaki disease (KD)combined with systemic juvenile idiopathic arthritis (SJIA). After the failed therapy of administration of IVIG,the child then developed arthritis. The diagnosis was corrected to KD complicated with SJIA. The symptoms were alleviated after effective treatment. Albeit KD and SJIA share similar manifestations in clinical and laboratory tests,much attention should be paid to distinguish the differences and avoid treatment delay.%临床工作中,儿科发热患儿多见,病因多样,部分患儿病情复杂且变化快。该文报道了1例川崎病合并幼年特发性关节炎患儿的诊治过程。患儿经丙种球蛋白治疗无反应后,出现关节炎症状,修正诊断为川崎病合并全身型幼年特发性关节炎,调整治疗方案后得到缓解。该例提示,川崎病及全身型幼年特发性关节炎虽有许多类似的临床表现及实验室数据,但应根据其不同点进一步鉴别诊断,以防延误治疗。

  16. Detection of coronary artery damage at sub-acute phase of Kawasaki disease with myocardial perfusion imaging and two-dimensional echocardiography

    International Nuclear Information System (INIS)

    Objective: To compare the diagnostic values of rest 99Tcm-MIBI MPI and two-dimensional echocardiography (2-DE) for the detection of coronary artery damage at sub-acute phase of Kawasaki disease (KD). Methods: Twenty-four children (14 males and 10 females, mean age: (2.50±2.19) years) with KD at sub-acute phase were studied between August 1999 and March 2012. All patients underwent rest 99Tcm-MIBI MPI and 2-DE. χ2 and Wilcoxon rank sum tests with SPSS 13.0 were used for data analysis. Results: The positive rate of MPI was 66.67% (16/24), significantly higher than that of 2-DE (37.50%,9/24; χ2=4.00, P<0.05). There was no significant difference between the duration for definite diagnosis by MPI and 2-DE ((13.79±2.86) vs (15.89±5.60) d; Z=-0.746, P>0.05). Eight of 24 patients (33.33%) had positive results for both MPI and 2-DE, and 7 patients (29.17%) had negative findings for both methods. Eight patients (8/24, 33.33%) were positive on MPI but negative on 2-DE, and 1 patient (1/24, 4.17%) was positive on 2-DE but negative on MPI. The areas of myocardial ischemia detected by MPI in 4 patients were consistent with the findings by 2-DE. Conclusions: Rest 99Tcm-MIBI MPI is a valuable noninvasive method to evaluate the coronary circulation and myocardial ischemia in KD patients at sub-acute phase. In combination with MPI, 2-DE might provide more comprehensive information for the evaluation of KD. (authors)

    In patients with diabetes mellitus, cardiovascular disease is the principal cause of mortality and chest pain is the most frequent symptom in patients with stable and acute coronary artery disease. However, there is little knowledge concerning the pervasiveness of uncommon presentations in diabetics. The symptomatology of acute coronary syndrome, which comprises both pain and non-pain symptoms, may be affected by traditional risk factors such as age, gender, smoking, hypertension, diabetes, and dyslipidemia. Such atypical symptoms may range from silent myocardial ischemia to a wide spectrum of non-chest pain symptoms. Worldwide, few studies have highlighted this under-investigated subject, and this aspect of ischemic heart disease has also been under-evaluated in the major clinical trials. The results of these studies are highly diverse which makes definitive conclusions regarding the spectrum of atypical presentation of acute and even stable chronic coronay artery disease difficult to confirm. This may have a significant impact on the morbidity and mortality of coronary artery disease in diabetics. In this up-to-date review we will try to analyze the most recent studies on the atypical presentations in both acute and chronic ischemic heart disease which may give some emphasis to this under-investigated topic.

    BACKGROUND: Approximately 1% of all cases of Alzheimer's disease are inherited autosomal dominantly, and to date, three causative genes have been found, the Presenilin 1 (PSEN1) gene, the Presenilin 2 (PSEN2) gene and the Amyloid precursor protein (APP) gene. We describe atypical phenotypic...... features in a family with a pathogenic APP gene mutation and discuss possible explanations for these atypical features. METHODS AND RESULTS: We report a family with a history of dementia compatible with autosomal dominant transmission. The disease course in the proband was not typical for Alzheimer......'s disease as the diagnosis was preceded by 8 years of an isolated amnesia. Further, the proband had epilepsy with complex partial seizures and central degenerative autonomic failure as determined by clinical physiology.

    Conventional single tensor diffusion analysis models have provided mixed findings in the substantia nigra of Parkinson's disease, but recent work using a bi-tensor analysis model has shown more promising results. Using a bi-tensor model, free-water values were found to be increased in the posterior substantia nigra of Parkinson's disease compared with controls at a single site and in a multi-site cohort. Further, free-water increased longitudinally over 1 year in the posterior substantia nigra of Parkinson's disease. Here, we test the hypothesis that other parkinsonian disorders such as multiple system atrophy and progressive supranuclear palsy have elevated free-water in the substantia nigra. Equally important, however, is whether the bi-tensor diffusion model is able to detect alterations in other brain regions beyond the substantia nigra in Parkinson's disease, multiple system atrophy, and progressive supranuclear palsy and to accurately distinguish between these diseases. Free-water and free-water-corrected fractional anisotropy maps were compared across 72 individuals in the basal ganglia, midbrain, thalamus, dentate nucleus, cerebellar peduncles, cerebellar vermis and lobules V and VI, and corpus callosum. Compared with controls, free-water was increased in the anterior and posterior substantia nigra of Parkinson's disease, multiple system atrophy, and progressive supranuclear palsy. Despite no other changes in Parkinson's disease, we observed elevated free-water in all regions except the dentate nucleus, subthalamic nucleus, and corpus callosum of multiple system atrophy, and in all regions examined for progressive supranuclear palsy. Compared with controls, free-water-corrected fractional anisotropy values were increased for multiple system atrophy in the putamen and caudate, and increased for progressive supranuclear palsy in the putamen, caudate, thalamus, and vermis, and decreased in the superior cerebellar peduncle and corpus callosum. For all disease

    We describe an 18-year-old patient with psychomotor retardation and abnormally short metatarsi and metacarpals but no other signs of classic Refsum disease. Molecular analysis of the phytanoyl-coenzyme A hydroxylase gene revealed a homozygous deletion causing a frameshift. Surprisingly, L-pipecolic acid was elevated in plasma, and microscopy of the liver showed a reduced number of peroxisomes per cell and a larger average peroxisome size. These abnormal peroxisomes lacked catalase as did peroxisomes in fibroblasts of this patient. Such generalized peroxisomal abnormalities are not present in classic Refsum disease.

    Charcot-Marie-Tooth (CMT) 1A is the most common form of CMT disease and is characterized by duplication of Peripheral myelin protein 22 (PMP22) gene. We report a boy with genetically confirmed CMT1A disease having clinical involvement of hypoglossal and glossopharyngeal nerves, as well as asymmetrical and primarily upper limb involvement. These atypical features widen the clinical spectrum of CMT1A, leading to interesting observations about PMP22 gene related disorders and varied clinical expression of similar genetic mutations.

    2016-01-01

    Full Text Available Introduction Cat scratch disease (CSD is an infectious disease caused by the Gram-negative rod Bartonella henselae (BH. It usually leads to subacute loco-regional lymphadenitis occasionally associated with fever. In most of the cases, it resolves spontaneously within 4 - 6 weeks. However, CSD has also been associated with other atypical presentations. Case Presentation We reported a series of seven children with unusual symptoms of CSD. In particular, we described the case of a child with ptosis, miosis and enophtalmy, suggesting Horner syndrome, associated with cervical lymphadenitis. Cat scratch was mentioned in only one patient, while four of them mentioned a recent contact with cats. We reviewed and discussed the incidence of these atypical presentations of CSD as well as the therapeutic approaches recommended and the available diagnostic tools. Conclusions This paper highlighted the need to exclude CSD in children with unexplained symptoms such as prolonged fever, hepatosplenic lesion and osteomyelitis.

    Erythema migrans is the initial sign in the majority of patients infected with Borrelia, the genus of spirochetes that causes Lyme disease. Early identification and treatment decrease the risk of progression to later stages of disease. Although a "bull's eye" appearance owing to lesional clearing is considered classic for erythema migrans, this feature is surprisingly often lacking among patients in the United States. Furthermore, cutaneous Lyme disease can exhibit a wide range of morphologic variability in a minority of patients. Herein, we describe the case of a patient with Lyme disease in which the presence of atypical vesicular features, in conjunction with the initial absence of clearing, resulted in multiple misdiagnoses and delayed treatment. We also review the literature on the epidemiology and management of erythema migrans for cases in which the diagnosis may pose a challenge.

  10. Detection of atypical bile acids in disease states and their identification by gas chromatography-mass spectrometry-computer techniques

    1978-01-01

    The study of the bile acid constituents of serum, bile, urine, and stool of patients exhibiting liver disease has increased in importance with the availability of newer methods for their detection and identification. A cogent question for study has been whether specific bile acids are toxic and thus are the cause of liver disease, or whether they accumulate as a result of disease-induced alteration in metabolism. Examining a wide variety of clinical samples, we have observed that many patients with diagnosed cholestasis show the presence of atypical bile acids due to metabolic aberrations in either the side chain or in the steroid ring. Because cholestasis represents a spectrum of diseases with differing metabolic and/or anatomic defects and because our studies cover a variety of cholestatic states, we have sought to establish a correlation between the presence of these atypical bile acids and the disease state. The complexity of the bile acid mixtures to be examined requires that gas chromatographic-mass spectrometric-computer techniques be used to provide a reliable analysis. It is believed that atypical bile acids can be readily identified by GC/CI mass spectrometry with great sensitivity. It is also believed that such bile acid analysis may prove useful to the study and diagnosis of liver disease. Present data suggest that the identification of atypical bile acids in biological samples may enable differentiation between different types of intrahepatic cholestasis. Such analyses may prove useful to distinguish specific diseases, such as Byler's disease (and Byler's-like cholestasis) from other types of cholestasis and may distinguish diseases involving mitochondrial defects. Finally, the presence of atypical bile acids may indicate, by the particular compounds formed, where and what kind of damage occurs in a disease and may ultimately establish if these atypical bile acids are a cause or effect of the liver damage.

    Full Text Available Background. Hand-foot-and-mouth disease (HFMD is a disease that had similar manifestations to chickenpox, impetigo, and measles, which is easy to misdiagnose and subsequently causes delayed therapy and subsequent epidemic. To date, no study has been conducted to report the clinical and epidemiological characteristics of atypical HFMD. Methods. 64 children with atypical HFMD out of 887 HFMD children were recruited, stool was collected, and viral VP1 was detected. Results. The atypical HFMD accounted for 7.2% of total HFMD in the same period (64/887 and there were two peaks in its prevalence in nonepidemic seasons. Ten children (15.6% had manifestations of neurologic involvement, of whom 4 (6.3% were diagnosed with severe HFMD and 1 with critically severe HFMD, but all recovered smoothly. Onychomadesis and desquamation were found in 14 patients (21.9% and 15 patients (23.4%, respectively. The most common pathogen was coxsackievirus A6 (CV-A6 which accounted for 67.2%, followed by nontypable enterovirus (26.6%, enterovirus 71 (EV-A71 (4.7%, and coxsackievirus A16 (A16 (1.5%. Conclusions. Atypical HFMD has seasonal prevalence. The manifestations of neurologic involvement in atypical HFMD are mild and usually have a good prognosis. CV-A6 is a major pathogen causing atypical HFMD, but not a major pathogen in Chongqing, China.

    Atypical hemolytic uremic syndrome (aHUS) is a genetic ultrarare renal disease associated with overactivation of the alternative pathway of complement. Four gain-of-function mutations that form a hyperactive or deregulated C3 convertase have been identified in Factor B (FB) ligand binding sites. Here, we studied the functional consequences of 10 FB genetic changes recently identified from different aHUS cohorts. Using several tests for alternative C3 and C5 convertase formation and regulation, we identified two gain-of-function and potentially disease-relevant mutations that formed either an overactive convertase (M433I) or a convertase resistant to decay by FH (K298Q). One mutation (R178Q) produced a partially cleaved protein with no ligand binding or functional activity. Seven genetic changes led to near-normal or only slightly reduced ligand binding and functional activity compared with the most common polymorphism at position 7, R7. Notably, none of the algorithms used to predict the disease relevance of FB mutations agreed completely with the experimental data, suggesting that in silico approaches should be undertaken with caution. These data, combined with previously published results, suggest that 9 of 15 FB genetic changes identified in patients with aHUS are unrelated to disease pathogenesis. This study highlights that functional assessment of identified nucleotide changes in FB is mandatory to confirm disease association. PMID:24652797

    Full Text Available Introduction. Behçet's disease (BD is a form of vasculitis of unknown etiology which is rare in our environment. It is characterized by a variety of clinical manifestations and usually affects young adults. Recurrent oral and genital ulcers are a characteristic and extremely frequent symptom, but mortality is linked with more significant symptoms such as aortic pseudoaneurysm, pulmonary pseudoaneurysm, and cerebral venous thrombosis. Patient and Method. We present a case of a young male with atypical BD and severe polyvascular involvement (previous cerebral venous thrombosis and current peripheral venous thrombosis, acute ischemia, and peripheral arterial pseudoaneurysm who required urgent surgical intervention due to a symptomatic external iliac pseudoaneurysm. Result. The pseudoaneurysm was successfully treated, we performed an iliofemoral bypass, and we treated it with steroids and immunosuppressive therapy. Conclusions. These rare clinical manifestations highlight the importance of considering BD in young patients, even in usual cases of vascular intervention, whether arterial or venous in nature.

    Objectives:To explore the diagnostic value of ultrasound cardiogram in coronary artery lesions resulting from Kawasaki disease. Methods:Doppler ultrasound technique was used to detect 26 cases of coronary artery lesions resulting from Kawasaki disease treated from October 2006 to March 2014 and to observe the inner diameter and wall thickness of the coronary artery, echo intensity and whether there was an aneurysm formed. Results:The display rate was 100 % for the left main coronary artery and right coronary artery in the healthy group;15 cases (57. 7 %) of coronary artery lesions were detected in the group with coronary artery disease , including 14 cases of coronary artery diameter expansion, 2 cases of coronary artery inner diameter expansion with intimal thickening and pericardial effusion respectively, 1 case of right coronary artery aneurysm;the earliest onset of coronary artery lesions occurred in the first 5-7 days. Conclusion:It is safe, convenient, fast and visual to use ultrasound car-diogram for diagnosing coronary artery lesions resulting from Kawasaki disease, which is of diagnostic value. It can be considered to have the priority in the imaging test , but it's a bit difficult to check the damage to the distal coronary artery.%目的:探讨超声心动图对小儿川崎病冠状动脉病变的诊断价值。方法:以50例健康儿童的超声监测值为参照,应用多普勒超声技术对2006年10月至2014年3月进行治疗的26例川崎病冠状动脉病变的患儿进行检测,观察冠状动脉内径、冠状动脉壁厚度、回声的强度及有无动脉瘤形成。结果:健康组左冠状动脉主干及右冠脉显示率为100%,病变组检出冠状动脉病变15例(57.7%),其中冠状动脉内径扩张为14例,冠状动脉内径扩张合并内膜增厚为2例,合并心包积液2例,1例为右冠状动脉瘤。冠脉病变最早发生在起病5~7d。结论:超声心动图用于诊断和随访小儿川崎病冠状动脉病

  17. Cine-CT diagnosis of coronary artery aneurysms in patients with Kawasaki

    International Nuclear Information System (INIS)

    Coronary artery aneurysms (CAA) are the most serious late sequelae of Kawasaki disease, and periodic screening examinations are necessary. Two-dimensional (2D) echocardiography represents the standard screening method; however, visualization of the distal coronary arteries is often limited. This report documents the complimentary role of cine-CT with 2D echocardiography in the evaluation of CAA induced by Kawasaki disease. Six pediatric patients with coronary aneurysms were evaluated with both 2D echocardiography and cine-CT. Cine-CT detected ten of 11 lesions. The one misdiagnosed CAA was one of the two contiguous aneurysms. Owing to intersection thickness, these two discrete aneurysms were interpreted as a solitary aneurysm. Cine-CT detected one CAA not initially visualized on echocardiography. Cine-CT is effective and complementary to 2D echocardigraphy as a noninvasive method for the evaluation of coronary artery aneurysms occurring as sequelae of Kawasaki disease

    AIM: To analyze whether the presence of Helicobacter pylori(H. pylori) infection could affect the quality of symptoms in gastro-esophageal reflux disease(GERD) patients. METHODS: one hundred and forty-four consecutive patients referred to our Unit for suspected GERD were recruited for the study. All patients underwent esophageal p H-metric recording. For those with a positive test, C13 urea breath test was then performed to assess the H. pylori status. GERD patients were stratified according to the quality of their symptoms and classified as typical, if affected by heartburn and regurgitation, and atypical if complaining of chest pain, respiratory and ears, nose, and throat features. H. pylori-negative patients were also asked whether they had a previous diagnosis of H. pylori infection. If a positive response was given, on the basis of the time period after successful eradication, patients were considered as "eradicated"(E) if H. pylori eradication occurred more than six months earlier or "recently eradicated" if the therapy had been administered within the last six months. Patients without history of infection were identified as "negative"(N). χ2 test was performed by combining the clinical aspects with the H. pylori status.RESULTS: one hundred and twenty-nine of the 144 patients, including 44 H. pylori-positive and 85 H. pylori-negative(41 negative, 21 recently eradicated, 23 eradicated more than 6 mo before), were eligible for the analysis. No difference has been found between H. pylori status and either the number of reflux episodes(138 ± 23 vs 146 ± 36, respectively, P = 0.2, not significant) or the percentage of time with pH values < 4(6.8 ± 1.2 vs 7.4 ± 2.1, respectively, P = 0.3, not significant). The distribution of symptoms was as follows: 13 typical(30%) and 31 atypical(70%) among the 44 H. pylori-positive cases; 44 typical(52%) and 41 atypical(48%) among the 85 H. pylori-negative cases,(P = 0.017 vs H. pylori +; OR = 2.55, 95%CI: 1

    Kawasaki disease (KD) is an acute, self-limited vasculitis of children and the principal cause of acquired heart disease in children in developed countries. The recent follow-up studies of KD revealed that cardiac sequelae had been observed for many years in a minority of patients with KD. Cardiac sequelae especially the coronary artery aneurysm is the leading cause of ischemic heart disease or even the sudden death.The long-term management of KD was developed in many countries in order to prevent the cardiac events.This paper reviews the long-term prognosis and follow-up of KD.%近年对川崎病的追踪随访发现,大部分患儿预后良好,但仍有少数患儿长期遗留心血管后遗症,可发展为缺血性心脏病,一旦发生心肌梗死,病死率高.因此,美国、日本及我国等均制订了相应的川崎病患儿长期随访方案,应用各种随访手段以观察其冠状动脉损害及转归,预防川崎病引起的心血管意外发生.

    Type and frequency of systemic and neurologic manifestations of Behçet's disease (BD) vary with ethnicity. In Brazil, BD occurs as sporadic cases. We describe clinical and radiological features of 36 Brazilian patients of mixed ethnicity with neuro-Behçet's disease (NBD). Medical records of 178 BD patients were reviewed and 36 (20%) NBD patients were identified. Twenty-one NBD patients (58.3%) were female and 27 (75%) presented with parenchymal manifestations. Brainstem involvement was the most common neurologic syndrome (41.7%). Seizures (27.8%), isolated aseptic meningitis (16.7%), optic neuropathy (ON) (16.7%), cerebral venous thrombosis (CVT) (8.3%), peripheral neuropathy (2.8%), and spinal cord involvement (5.6%) were other neurologic manifestations observed among Brazilian NBD patients. Eighteen (50%) had at least one relapse, and isolated aseptic meningitis was the most common relapsing manifestation. No significant differences concerning the number of relapses between parenchymal and non-parenchymal groups were found. A multivariate model including disease duration, cell count in spinal fluid, cyclosporine use, immunosuppressive use at disease onset, age at NBD onset, and ON did not reveal any significant associations with NBD relapse. There was a low frequency of CVT and an unexpected higher number of isolated aseptic meningitis. Brazilian NBD patients present more parenchymal and atypical manifestations, and relapse more often than NBD patients from other populations. PMID:22169955

    Highlights: Black-Right-Pointing-Pointer The expression of the atypical cadherin FAT1 is increased in chronic liver disease. Black-Right-Pointing-Pointer FAT1 expression goes up during the activation of hepatic stellate cells (HSCs). Black-Right-Pointing-Pointer Activated HSCs are the cellular source of enhanced FAT1 expression in diseased livers. Black-Right-Pointing-Pointer FAT1 enhanced NFkB activity and resistance to apoptosis in activated HSCs. Black-Right-Pointing-Pointer FAT1 is a new therapeutic target for prevention and treatment of hepatic fibrosis. -- Abstract: Hepatic fibrosis can be considered as wound healing process in response to hepatocellular injury. Activation of hepatic stellate cells (HSCs) is a key event of hepatic fibrosis since activated HSCs are the cellular source of enhanced extracellular matrix deposition, and reversion of liver fibrosis is accompanied by clearance of activated HSCs by apoptosis. The atypical cadherin FAT1 has been shown to regulate diverse biological functions as cell proliferation and planar cell polarity, and also to affect wound healing. Here, we found increased FAT1 expression in different murine models of chronic liver injury and in cirrhotic livers of patients with different liver disease. Also in hepatic tissue of patients with non-alcoholic steatohepatitis FAT1 expression was significantly enhanced and correlated with collagen alpha I(1) expression. Immunohistochemistry revealed no significant differences in staining intensity between hepatocytes in normal and cirrhotic liver tissue but myofibroblast like cells in fibrotic septa of cirrhotic livers showed a prominent immunosignal. Furthermore, FAT1 mRNA and protein expression markedly increased during in vitro activation of primary human and murine HSCs. Together, these data indicated activated HSCs as cellular source of enhanced FAT1 expression in diseased livers. To gain insight into the functional role of FAT1 in activated HSCs we suppressed FAT1 in these

    Multiple cases of atypical scrapie in the same holding and co-existence with classical scrapie have been reported in Great Britain. A two-stage simulation tool was developed by combining a sampling algorithm and a hierarchical Bayesian model to simulate the number of positive cases of atypical scrapie from: (i) random sampling and (ii) using the actual sampled population in Great Britain, being the output probability of detection of flocks with one and more cases. Cluster analysis was conducted to assess the level of geographical over- and under-sampling over the years. The probability of detecting at least two cases of atypical scrapie in the same holding is much lower in simulated random data than in simulated actual data for all scenarios. Sampling bias in the selection of sheep for testing led to multiple sampling from fewer but larger holdings, Scotland, and areas of Wales were under-sampled and the South-West and East of England oversampled. The pattern of atypical scrapie cases observed is unlikely to be explained by a multi-case event epidemiologically linked. The co-existence of classical and atypical scrapie is a rare event with 19 holdings detected in GB and does not suggest an epidemiological link between the two types of disease. PMID:26976340

    Objective To investigate the prognosis of patients with Kawasaki's disease complicated with coronary artery lesion and to provide evidence for diagnosis and treatment of these patients. Methods This study was conducted during January 2002 to June 2007. All patients diagnosed as Kawasaki's disease complicated with coronary artery lesions were from the Affiliated Hospital of Guilin Medical College, the Second People's Hospital of Guangxi Province and Guilin Women and Childrens' Hospital. All cases were echocardiogram examined in month 3, 6, 12, 24 and 36 in the purpose of observing the morphology of coronary artery. The study subjects were re-categorized to the groups of mild, moderate dilatation of coronary artery and giant coronary aneurysm, based on the severity of coronary artery lesion. The results of these results of the three groups were compared. Results Eighty-four cases in the mild group, 27 cases in the moderate group and 8 cases in the giant coronary aneurysm. The recovery cases were 23 (27%), 3 (11%) and 0 in the 3 groups respectively at month 3. The above numbers were 44 (52%), 8 (30%) and 0 respectively at month 6.The numbers were 69(82%), 13 (48%) and 1 (13%) at month 12. The numbers were 78 (93%), 19 (70%), 3 (38%) at month 24. The numbers were 82(98%), 20(74%) and 4(50%) at month 36. Thirteen patients were treated with adenosine-triphosphate (ATP) stress echocardiography examiantion, 5 patients were evaluated by coronary angiography,and 4 patients were tested by 64-slice CT coronary reconstruction. Part of the patients were found to have coronary stenosis or occlusion. Conclusion Patients of Kawasaki's disease often have concurrent coronary artery lesions. Patients with mild dilatation of the coronary artery are the most commonly seen and have the best prognosis. On the contrast, patients with giant coronary aneurysm are the lest common situation and is the worst in prognosis. Part of them will develop coronary artery stenosis or occlusion in late

    2013-01-01

    Full Text Available Paroxysmal non-kinesigenic dyskinesia (PNKD is a rare hyperkinetic movement disorder and falls under the category of paroxysmal movement disorders. In this condition, episodes are spontaneous, involuntary, and involve dystonic posturing with choreic and ballistic movements. Attacks last for minutes to hours and rarely occur more than once per day. Attacks are not typically triggered by sudden movement, but may be brought on by alcohol, caffeine, stress, fatigue, or chocolate. We report a patient with multiple atypical features of PNKD. She had a 7-year history of this condition with onset at the age of 59, and a remote history of Graves′ disease requiring total thyroidectomy. The frequency of attacks in our case ranged from five to six times a day to a minimum of twice per week, and the duration of episode was short, lasting not more than 2 min. Typically, PNKDs occur at a much younger age and have longer attack durations with low frequency. Administering clonazepam worked to reduce her symptoms, although majority of previous research suggests that pharmacological interventions have poor outcomes.

    2011-01-01

    The main complication of the Kawasaki disease (KD) is coronary artery lesions (CAL) , and it has become one of the most common acquired heart diseases in children. Recent studies show that CAL is related to the degradation of the vascular wall extracellular matrix, and the degradation of the vascular wall extracellular is related to the activation of MMPs and (or) the TIMPs out of balance. Therefore, matrix metalloproteinases (MMPs) and its inhibitors (TIMPs) play an important role in occurrence and development of coronary lesions. Application of TIMPs to regulaLe the level of MMPs is a new direction to treatment and prevention of coronary artery lesions.%冠状动脉损害(CAL)是川崎病(KD)的主要并发症,现已成为儿童最常见的后天性心脏病之一.近年来研究表明,川崎病冠状动脉损害与血管壁细胞外基质(ECM)降解有关,而血管壁细胞外基质降解与基质金属蛋白酶(matrix metalloproteinases,MMPs)激活和(或)与其组织抑制剂(tissue inhibitor of matrix metalloprotein-ases,TIMPs)的平衡被破坏有关.因此,基质金属蛋白酶(MMPs)及其抑制剂(TIMPs)在川崎病冠脉损害的发生发展中起着重要作用,应用TIMPs对MMPs水平进行调控是KD治疗及预防冠脉并发症的一个新方向.

  13. An atypical kinase under balancing selection confers broad-spectrum disease resistance in Arabidopsis.

    Directory of Open Access Journals (Sweden)

    Carine Huard-Chauveau

    Full Text Available The failure of gene-for-gene resistance traits to provide durable and broad-spectrum resistance in an agricultural context has led to the search for genes underlying quantitative resistance in plants. Such genes have been identified in only a few cases, all for fungal or nematode resistance, and encode diverse molecular functions. However, an understanding of the molecular mechanisms of quantitative resistance variation to other enemies and the associated evolutionary forces shaping this variation remain largely unknown. We report the identification, map-based cloning and functional validation of QRX3 (RKS1, Resistance related KinaSe 1, conferring broad-spectrum resistance to Xanthomonas campestris (Xc, a devastating worldwide bacterial vascular pathogen of crucifers. RKS1 encodes an atypical kinase that mediates a quantitative resistance mechanism in plants by restricting bacterial spread from the infection site. Nested Genome-Wide Association mapping revealed a major locus corresponding to an allelic series at RKS1 at the species level. An association between variation in resistance and RKS1 transcription was found using various transgenic lines as well as in natural accessions, suggesting that regulation of RKS1 expression is a major component of quantitative resistance to Xc. The co-existence of long lived RKS1 haplotypes in A. thaliana is shared with a variety of genes involved in pathogen recognition, suggesting common selective pressures. The identification of RKS1 constitutes a starting point for deciphering the mechanisms underlying broad spectrum quantitative disease resistance that is effective against a devastating and vascular crop pathogen. Because putative RKS1 orthologous have been found in other Brassica species, RKS1 provides an exciting opportunity for plant breeders to improve resistance to black rot in crops.

    Full Text Available Atypical depression is defined as a specifier of major depressive disorder. Columbia criteria for atypical depression are commonly used to make a diagnosis. Female sex, onset at early age, chronic course, and higher rate of comorbidity (especially anxiety disorder and bipolar disorder is noteworthy in atypical depression. Although, the atypical depression seems to support the familial genetic transition, there is not any specific study supporting these data. In the treatment of atypical depression, monoamine oxidase inhibitors are reported to be more effective than tricyclic antidepressants. In recent studies, selective serotonin reuptake inhibitors have also proven to be efficient.

    Public and animal health controls to limit human exposure to animal prions are focused on bovine spongiform encephalopathy (BSE), but other prion strains in ruminants may also have zoonotic potential. One example is atypical/Nor98 scrapie, which evaded statutory diagnostic methods worldwide until the early 2000s. To investigate whether sheep infected with scrapie prions could be another source of infection, we inoculated transgenic mice that overexpressed human prion protein with brain tissue...

  5. Efficacy of iodine-123-15-(p-iodophenyl)-3-R,S-methylpentadecanoic acid single photon emission computed tomography imaging in detecting myocardial ischemia in children with Kawasaki disease

    International Nuclear Information System (INIS)

    To evaluate its efficacy in detecting myocardial ischemia in children, iodine-123-labeled 15-(p-iodophenyl)-3-R,S-methylpentadecanoic acid (BMIPP) myocardial single photon emission computed tomography (SPECT) imaging was performed in 16 pediatric patients with Kawasaki disease (KD, 11 male, 5 female; mean age and range: 13 years 8 months and 8 years 11 months to 17 years 7 months). Five children with chest pain and no cardiac disease were studied as controls (2 male, 3 female; mean age and range: 13 years 4 months and 9 years 4 months to 17 years 11 months). Selective coronary angiography was also performed in the 16 patients to evaluate the location of coronary stenosis and coronary aneurysms. The SPECT images were expressed as polar maps (Bull's eye maps) and the 'defect' area was defined as where the uptake of BMIPP was less than the standardized BMIPP images of the 5 control children. In the 16 patients, 33 segments had coronary aneurysms and 10 (10/33: 30.3%) had significant coronary stenosis on selective coronary angiography. Nine of the 10 (90%) segments with significant coronary stenosis showed a defect on the BMIPP image whereas only 6 of the 23 (26.1%) segments without coronary stenosis showed a defect on BMIPP imaging. The sensitivity of BMIPP SPECT imaging for detection of coronary stenosis was 90% (9/10) and its specificity was 73.9% (17/23), whereas the sensitivity of 201Tl SPECT imaging was 80% (8/10) and its specificity was 60% (14/23). There was no significant difference between the BMIPP and 201Tl SPECT images in either the sensitivity or specificity for the detection of coronary stenosis. In the present series, only one case had discordant BMIPP uptake (BMIPP uptake201Tl uptake) in which there was a large coronary aneurysm and re-canalization after complete obstruction at segment 1 of the right coronary artery. This discordant BMIPP uptake reflects the possibility of ischemic but viable myocardium after re-canalization of a large aneurysm in KD

    2014-01-01

    The authors described a case of a patient with co-existing endolymphatic sac tumor (ELST) and hemangioblastoma in the posterior cranial fossa, which belonged to a subtype of Von Hippel-Lindau (VHL) disease confirmed by the test of VHL-gene. The signs in this 42-year-old female included intermittent headache and dizziness. Imaging revealed a giant mass in the right cerebellopontine angle (CPA) region and another lesion in the left cerebellar hemisphere. The results of biopsy after two operations confirmed the diagnosis respectively. Both of the tumors were resected totally. Nevertheless, we had to confess the misdiagnosis as vascular tumor instead of ELST at the initial diagnosis because of the rarity of ELST associated with atypical histological characteristics. The purposes we reported this case were to describe the atypical pathological feature of ELST and the mutation of germline VHL not mentioned in previously literature, furthermore, to foster understanding of ELSTs with the avoidance of the similar misdiagnosis as far as possible in future.

    We describe an atypical neuropathological phenotype of sporadic Creutzfeldt-Jakob disease in a 76-year-old man. The clinical symptoms were characterized by progressive dementia, gait ataxia, rigidity and urinary incontinence. The disease duration was 6 weeks. MRI did not show prominent atrophy or hyperintensities in cortical areas, striatum or thalamus. Biomarker examination of the cerebrospinal fluid deviated from that seen in pure Alzheimer's disease. Triphasic waves in the EEG were detected only later in the disease course, while 14-3-3 assay was positive. PRNP genotyping revealed methionine homozygosity (MM) at codon 129. Neuropathology showed classical CJD changes corresponding to the MM type 1 cases. However, a striking feature was the presence of abundant kuru-type plaques in the white matter. This rare morphology was associated with neuropathological signs of intranuclear inclusion body disease and advanced stage of argyrophilic grain disease. These alterations did not show correlation with each other, thus seemed to develop independently. This case further highlights the complexity of neuropathological alterations in the ageing brain.

  9. Disease isolates of Streptococcus pseudopneumoniae and non-typeable S. pneumoniae presumptively identified as atypical S. pneumoniae in Spain.

    Directory of Open Access Journals (Sweden)

    Dora Rolo

    Full Text Available We aimed to obtain insights on the nature of a collection of isolates presumptively identified as atypical Streptococcus pneumoniae recovered from invasive and non-invasive infections in Spain. One-hundred and thirty-two isolates were characterized by: optochin susceptibility in ambient and CO(2-enriched atmosphere; bile solubility; PCR-based assays targeting pneumococcal genes lytA, ply, pspA, cpsA, Spn9802, aliB-like ORF2, and a specific 16S rRNA region; multilocus sequence analysis; and antimicrobial susceptibility. By multilocus sequence analysis, 61 isolates were S. pseudopneumoniae, 34 were pneumococci, 13 were S. mitis, and 24 remained unclassified as non-pneumococci. Among S. pseudopneumoniae isolates, 51 (83.6% were collected from respiratory tract samples; eight isolates were obtained from sterile sources. High frequency of non-susceptibility to penicillin (60.7% and erythromycin (42.6% was found. Only 50.8% of the S. pseudopneumoniae isolates displayed the typical optochin phenotype originally described for this species. None harbored the cpsA gene or the pneumococcal typical lytA restriction fragment length polymorphism. The Spn9802 and the specific 16S rRNA regions were detected among the majority of the S. pseudopneumoniae isolates (n = 59 and n = 49, respectively. The ply and pspA genes were rarely found. A high genetic diversity was found and 59 profiles were identified. Among the S. pneumoniae, 23 were capsulated and 11 were non-typeable. Three non-typeable isolates, associated to international non-capsulated lineages, were recovered from invasive disease sources. In conclusion, half of the atypical pneumococcal clinical isolates were, in fact, S. pseudopneumoniae and one-fourth were other streptococci. We identified S. pseudopneumoniae and non-typeable pneumococci as cause of disease in Spain including invasive disease.

  10. A family with atypical Hailey Hailey disease--is there more to the underlying genetics than ATP2C1?

    Nina van Beek

    Full Text Available The autosomal dominant Hailey Hailey disease (HHD is caused by mutations in the ATP2C1 gene encoding for human secretory pathway Ca2+/Mn2+ ATPase protein (hSPCA1 in the Golgi apparatus. Clinically, HHD presents with erosions and hyperkeratosis predominantly in the intertrigines. Here we report an exome next generation sequencing (NGS based analysis of ATPase genes in a Greek family with 3 HHD patients presenting with clinically atypical lesions mainly localized on the neck and shoulders. By NGS of one HHD-patient and in silico SNP calling and SNP filtering we identified a SNP in the expected ATP2C1 gene and SNPs in further ATPase genes. Verification in all 3 affected family members revealed a heterozygous frameshift deletion at position 2355_2358 in exon 24 of ATP2C1 in all three patients. 7 additional SNPs in 4 ATPase genes (ATP9B, ATP11A, ATP2B3 and ATP13A5 were identified. The SNPs rs138177421 in the ATP9B gene and rs2280268 in the ATP13A5 gene were detected in all 3 affected, but not in 2 non affected family members. The SNPs in the ATP2B3 and ATP11A gene as well as further SNPs in the ATP13A5 gene could not be confirmed in all affected family members. One may speculate that besides the level of functional hSPCA1 protein, levels of other ATPase proteins may influence expressivity of the disease and might also contribute, as in this case, to atypical presentations.

Here we report an exome next generation sequencing (NGS) based analysis of ATPase genes in a Greek family with 3 HHD patients presenting with clinically atypical lesions mainly localized on the neck and shoulders. By NGS of one HHD-patient and in silico SNP calling and SNP filtering we identified a SNP in the expected ATP2C1 gene and SNPs in further ATPase genes. Verification in all 3 affected family members revealed a heterozygous frameshift deletion at position 2355_2358 in exon 24 of ATP2C1 in all three patients. 7 additional SNPs in 4 ATPase genes (ATP9B, ATP11A, ATP2B3 and ATP13A5) were identified. The SNPs rs138177421 in the ATP9B gene and rs2280268 in the ATP13A5 gene were detected in all 3 affected, but not in 2 non affected family members. The SNPs in the ATP2B3 and ATP11A gene as well as further SNPs in the ATP13A5 gene could not be confirmed in all affected family members. One may speculate that besides the level of functional hSPCA1 protein, levels of other ATPase proteins may influence expressivity of the disease and might also contribute, as in this case, to atypical presentations.

    Objective To evaluate the late endothelial function in children with coronary aneurysm due to Kawasaki disease (KD). Methods Thirty-one children with coronary aneurysms duc to KD who had the disease course for more than 1 year and twenty-one age-matched healthy children were enrolled. Brachial artery endothelium-dependent and -independent flow-mediated dilation (FMD), carotid arterial stiffness index (SI) and intima-media thickness (IMT) were measured by high-frequency ultrasound. Results There were 9 cases of medium and 22 cases of giant coronary aneurysms in the KD group. Twelve KD patients had evidence of myocardial ischemia. Compared to the normal controls, the endotheliumdependent FMD decreased (P < 0. 05), the carotid arterial SI increased (P < 0.05), and the carotid arterial intima-media thickness increased significantly (P <0.05) in children with coronary aneurysms due to KD. The endothelium-dependent FMD decreased more significantly in 12 KD patients with myocardial ischemia than in those without any evidence of myocardial ischemia (P < O. 05 ). Conclusions Late endothelial dysfunction exists in children with coronary aneurysms due to KD, especially in those with myocardial ischemia.%目的 评估川崎病(KD)冠脉瘤患儿远期血管内皮功能.方法 选择病程大于1年的合并中型以上冠脉瘤的川崎病患儿31例为研究对象,采用高分辨率超声仪进行肱动脉内皮依赖性和非依赖性舒张功能(FMD)、颈动脉僵硬度指数(SI)和颈动脉内中膜厚度(IMT)的检测.选择年龄相近的正常儿童21例作为对照.结果 31例KD冠脉瘤患儿中,中型冠脉瘤9例,冠脉巨大瘤22例,其中12例有心肌缺血.与对照组比较,KD冠脉瘤组患儿肱动脉血管内皮依赖性FMD减低(P<0.05),颈动脉SI增加(P<0.05),颈动脉IMT增厚(P<0.05).与无心肌缺血患儿相比,有心肌缺血患儿血管内皮依赖性FMD显著降低(P<0.05).结论 KD冠脉瘤患儿远期存在血管内皮功能障碍,

  15. Critical Overview of the Risk Scoring Systems to Predict Non-Responsiveness to Intravenous Immunoglobulin in Kawasaki Syndrome

    2016-02-01

    Full Text Available Kawasaki syndrome (KS is the most relevant cause of heart disease in children living in developed countries. Intravenous immunoglobulin (IVIG has a preventive function in the formation of coronary artery abnormalities and a poor strictly-curative action in established coronary damage. More than two decades ago, the Harada score was set to assess which children with KS should be subject to administration of IVIG, evaluating retrospectively a large cohort of patients with regard to age, sex and laboratory data. Nowadays, high dose IVIG is administered to all children with a confirmed diagnosis of KS, but a tool for predicting non-responsiveness to the initial infusion of IVIG has not been found. The prediction of IVIG resistance is a crucial issue, as recognising these high-risk patients should consent the administration of an intensified initial treatment in combination with IVIG in order to prevent coronary injuries. Few reports have focused on factors, referring to both clinical parameters and laboratory data at the onset of KS, in order to predict which patients might be IVIG non-responsive. We have analysed three different risk scores which were formulated to predict IVIG resistance in Japanese children with typical KS, but their application in non-Japanese patients or in those with incomplete and atypical patterns of the disease has been studied in a fragmentary way. Overall, our analysis showed that early and definite ascertainment of likely IVIG non-responders who require additional therapies reducing the development of coronary artery involvement in children with KS is still a challenge.

    ObjectiveTo investigate the association of two single nucleotide polymorphisms (SNPs) (rs2736340 and rs2618476) inBLK gene with Kawasaki disease (KD) and coronary artery lesion in Chinese Han children.MethodsIn the case-control study, 179 children with KD were selected and 182 healthy check-up children during the same period were selected as normal controls. The genotypes of two SNPs inBLK gene were detected using PCR-RFLP and the data were analyzed. ResultsThere was no difference in distribution of three genotypes (TT, CT, and CC) of SNP rs2736340 between KD group and control group (P=0.093). However, T allele frequency in KD group was signiifcantly higher than that in control group (P=0.021). The distribution of three genotypes (CC, CT, and TT) of SNP rs2618476 between KD group and control group was signiifcantly different (P=0.021). C allele frequency in KD group was signiifcantly higher than that in control group (P=0.006). The two SNPs inBLK gene were not associated with rash, hand-foot edema and coronary artery lesion (CAL), but SNP (rs2618476) was asso-ciated with oral mucosa lesions (P=0.018).ConclusionsThe SNP (rs2736340) inBLK gene was not associated with KD, but the T-allele was associated with KD. The SNP (rs2618476) was associated with KD in Han Chinese, and was also associated with oral mucosa lesions in KD patients.%目的:探讨汉族人群中BLK基因2个SNP位点rs2736340和rs2618476的多态性与川崎病(KD)以及动脉损伤的相关性。方法采取病例对照研究方法,分别选取179例KD患儿和同期182例体检正常儿童作为研究对象。利用PCR-RFLP的方法测定BLK基因两个SNP位点多态性分布,并进行统计分析。结果 SNP位点(rs2736340)3种基因型(TT、CT和CC)在KD组与对照组之间分布的差异无统计学意义(P=0.093);但KD患儿T等位基因频率高于对照组,差异有统计意义(P=0.021)。SNP位点(rs2618476)3种基因型(CC、CT、TT)分布,在KD患儿与对照组之间

    The association between bovine spongiform encephalopathy (BSE) and variant Creutzfeldt-Jakob disease (vCJD) has demonstrated that cattle transmissible spongiform encephalopathies (TSEs) can pose a risk to human health and raises the possibility that other ruminant TSEs may be transmissible to humans. In recent years, several novel TSEs in sheep, cattle and deer have been described and the risk posed to humans by these agents is currently unknown. In this study, we inoculated two forms of atypical BSE (BASE and H-type BSE), a chronic wasting disease (CWD) isolate and seven isolates of atypical scrapie into gene-targeted transgenic (Tg) mice expressing the human prion protein (PrP). Upon challenge with these ruminant TSEs, gene-targeted Tg mice expressing human PrP did not show any signs of disease pathology. These data strongly suggest the presence of a substantial transmission barrier between these recently identified ruminant TSEs and humans. PMID:22495232

  1. Review: A review on classical and atypical scrapie in caprine: Prion protein gene polymorphisms and their role in the disease.

    Scrapie is a naturally occurring transmissible spongiform encephalopathy in sheep and goat. It has been known for ~250 years and is characterised by the accumulation of an abnormal isoform of a host-encoded prion protein that leads to progressive neurodegeneration and death. Scrapie is recognised in two forms, classical and atypical scrapie. The susceptibility to both types of scrapie is influenced by polymorphisms of the prion protein gene (PRNP). Sheep susceptibility or resistance to classical scrapie is strongly regulated by the polymorphisms at codons 136, 154 and 171 of the PRNP. The genetic role in atypical scrapie in sheep has been defined by polymorphisms at codons 141, 154 and 171, which are associated with different degrees of risk in the occurrence of the ovine disease. Progress has been achieved in the prevention of scrapie in sheep due to efficient genetic breeding programmes based on eradication and control of the disease. In Europe, the success of these programmes has been verified by applying eradication and genetic selection plans. In general terms, the ovine selection plans aim to eliminate and reduce the susceptible allele and to enrich the resistant allele ARR. During outbreaks all susceptible animals are slaughtered, only ARR/ARR resistant rams and sheep and semi-resistant females are preserved. In the occurrence of scrapie positive goats a complete cull of the flock (stamping out) is performed with great economic loss and severe risk of extinction for the endangered breeds. The ability to select scrapie-resistant animals allows to define new breeding strategies aimed to boost genetic progress while reducing costs during scrapie outbreaks. Allelic variants of PRNP can be protective for caprine scrapie, and the knowledge of their distribution in goats has become very important. Over the past few years, the integration of genetic information on goat populations could be used to make selection decisions, commonly referred to as genetic selection

  4. Atypical Clinical and Diagnostic Features in Ménétrier's Disease in a Child

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Ménétrier's disease is one of the rarest protein-losing gastropathies in childhood. It is characterized clinically by non-specific gastrointestinal symptoms and edema, biochemically by hypoalbuminemia, and pathologically by enlarged gastric folds. In adults, this disease can be devastating with significant morbidity and mortality. In childhood, it is a self-limiting, transient and benign illness. Its treatment is largely supportive with total parenteral nutrition (TPN while oral intake is encouraged. Acute onset of vomiting in healthy school age children can be initially explained by acute viral gastroenteritis. However, persistent vomiting associated with hematemesis and severe abdominal pain should warrant further work-up. This case report illustrates a self-limiting and rare cause of protein-losing enteropathy called Ménétrier's disease that presented with several variant clinical features not typically described in association with this entity.

    Acute necrotizing encephalopathy of childhood (ANEC) is a disease entity seen nearly exclusively in East Asian children that is characterized by multifocal, symmetric lesions involving the thalami, brainstem, cerebellum, and white matter. We present a child who developed dramatic neurologic symptoms following a viral prodrome. Serial MRI examinations demonstrated characteristic lesions of ANEC, while laboratory analyses revealed evidence of acute infection with human herpesvirus-6 (HHV-6). We highlight the MRI findings in both the acute and convalescent phases of ANEC, discuss the implications of neuroimaging on the child's clinical course, and emphasize the integral role of the radiologist in correctly diagnosing this rare disease.

    Recent surveys conducted on Reunion Island coral reefs revealed an atypical manifestation of black band disease on the main framework building coral, Porites lutea. This BBD manifestation (PorBBD) presented a thick lighter-colored band, which preceded the typical BBD lesion. Whilst BBD aetiology has been intensively described worldwide, it remains unclear if corals with apparently similar lesions across coral reefs are affected by the same pathogens. Therefore, a multidisciplinary approach involving field surveys, gross lesion monitoring, histopathology and 454-pyrosequencing was employed to provide the first comprehensive characterization of this particular manifestation. Surveys conducted within two geomorphological zones over two consecutive summers and winters showed spatial and seasonal patterns consistent with those found for typical BBD. Genetic analyses suggested an uncharacteristically high level of Vibrio spp. bacterial infection within PorBBD. However, microscopic analysis revealed high densities of cyanobacteria, penetrating the compromised tissue as well as the presence of basophilic bodies resembling bacterial aggregates in the living tissue, adjacent to the bacterial mat. Additionally, classical BBD-associated cyanobacterial strains, genetically related to Pseudoscillatoria coralii and Roseofilum reptotaenium were identified and isolated and the presence of sulfate-reducers or sulfide-oxidizers such as Desulfovibrio and Arcobacter, previously shown to be associated with anoxic microenvironment within typical BBD was also observed, confirming that PorBBD is a manifestation of classical BBD.

    Full Text Available We describe a case report of an 80-year-old woman who presented with symptomatology compatible with an episode of major depression with catatonia. After psychiatric admission, electroconvulsive therapy (ECT was applied, but symptoms progressed with cognitive impairment, bradykinesia, widespread stiffness, postural tremor, and gait disturbance. After compatible magnetic resonance imaging (MRI, diffusion changes, and electroencephalogram (EEG findings the case was reoriented to Creutzfeldt-Jakob disease (CJD. The genetic study found a methionine/valine heterozygosity at codon 129 of the prion protein gene PrPSc. On followup, a significant clinical recovery turned out. For this reason, EEG and MRI were repeated and confirmed the findings. The patient subsequently demonstrated progressive clinical deterioration and died 21 months later. The diagnosis was verified postmortem by neuropathology. The vCJD subtype MV2 is indeed characterized by early and prominent psychiatric symptoms and a prolonged disease duration however no frank clinical recovery has before been reported.

    Thoracic aortic dissection is the most frequent cause of aortic emergency, and unless it is rapidly diagnosed and treated, the result is death. Helical computed tomography (CT) permits the diagnosis of acute aortic dissection with a sensitivity and specificity of nearly 100%. This imaging modality also enables differentiation between proximal aortic dissection (type A in the Stanford classification) and distal aortic dissection (Stanford type B), which are treated differently and have different prognoses. In 70% of patients in whom nontraumatic acute thoracic aortic dissection is diagnosed after evaluation with helical CT, scans show the typical signs of aortic dissection, with rupture and displacement of the intima. CT also can depict other pathologic entities with similar clinical manifestations, such as intramural hematoma and penetrating atherosclerotic ulcer. Awareness of the different radiologic appearances of these disease entities is essential for differential diagnosis. More than one-third of patients with aortic dissection show signs and symptoms indicative of systemic involvement. Because branch-vessel involvement may increase morbidity and mortality, in this group of patients it is important to evaluate the entire aorta so as to determine the distal extent of the dissection and detect any systemic involvement.

Methods A cohort of 60 children during the age of 2 to 4 years old was studied, which comprised 30 children at the convalescence phase of Kawasaki disease (KD group) and 30 healthy age-matched children (control group). Carotid arterial intima-media thickness (IMT) , malondialdehyde ( MDA) , interleukin-1 beta (IL-1|3) , interferon-gamma (IFN-7) and body mass index (BMI) were evaluated. Results IMT in KD group and control group was (0.40 ± 0.03) mm and (0.37 ± 0.04) mm respectively. IMT in KD group was higher than that in control group (P 0.05). IMT was positively correlated with the plasma level of MDA (r = 0.463, P < 0.05), but not significantly correlated with the levels of IL-iβ, IFN-7 and BMI. Conclusions The increased carotid IMT in children at the convalescent phase of Kawasaki disease is associated with oxidative stress.%目的 观察川崎病(KD)患儿恢复期颈动脉内膜-中膜厚度变化及相关因素,为防治KD血管病变提供科学依据.方法 收集30例2 ~ 4岁KD恢复期患儿及30例同年龄健康儿童,测定其颈动脉内膜-中膜厚度(IMT)、丙二醛(MDA)、白介素-1β(IL-1β)、γ-干扰素(IFN-γ)和体质指数(BMI).结果 KD患儿颈动脉IMT为(0.40 ± 0.03)mm,对照组为(0.37 ± 0.04)mm,两者比较差异有统计学意义.KD患儿MDA 为(2.56±0.18)nmol/ml,对照组为(2.09±0.24)nmol/ml,两者比较差异有统计学意义.两组间IL-1β、IFN-γ、BMI比较,差异均无统计学意义.直线相关分析显示,颈动脉IMT与MDA呈正相关(r = 0.463,P < 0.05),而与IL-1β、IFN-γ和 BMI水平均无相关性(P均> 0.05).结论 KD恢复期患儿颈动脉内膜-中膜增厚,与氧化应激有关.

    The goal of this study was to investigate repetitive finger tapping patterns in patients with Parkinson's disease (PD), progressive supranuclear palsy-Richardson syndrome (PSP-R), or multiple system atrophy of parkinsonian type (MSA-P). The finger tapping performance was objectively assessed in PD (n=13), PSP-R (n=15), and MSA-P (n=14) patients and matched healthy controls (HC; n=14), using miniature inertial sensors positioned on the thumb and index finger, providing spatio-temporal kinematic parameters. The main finding was the lack or only minimal progressive reduction in amplitude during the finger tapping in PSP-R patients, similar to HC, but significantly different from the sequence effect (progressive decrement) in both PD and MSA-P patients. The mean negative amplitude slope of -0.12°/cycle revealed less progression of amplitude decrement even in comparison to HC (-0.21°/cycle, p=0.032), and particularly from PD (-0.56°/cycle, p=0.001), and MSA-P patients (-1.48°/cycle, p=0.003). No significant differences were found in the average finger separation amplitudes between PD, PSP-R and MSA-P patients (pmsa-pd=0.726, pmsa-psp=0.363, ppsp-pd=0.726). The lack of clinically significant sequence effect during finger tapping differentiated PSP-R from both PD and MSA-P patients, and might be specific for PSP-R. The finger tapping kinematic parameter of amplitude slope may be a neurophysiological marker able to differentiate particular forms of parkinsonism. PMID:27343040

    Neuropathological studies report varying patterns of brain mineralization in Parkinson's diseases (PD), progressive supranuclear palsy (PSP), and Parkinson variant of multiple system atrophy (MSA-P). Susceptibility-weighted imaging (SWI) is the ideal magnetic resonance imaging (MRI) technique to detect mineralization of the brain. The purpose of this study was to test if SWI can differentiate PD, PSP, and MSA-P. Eleven patients with PD, 12 with PSP, 12 with MSA-P, and 11 healthy controls underwent SWI of the brain. Hypointensity of putamen, red nucleus, substantia nigra, and dentate nucleus in all groups were measured using an objective grading scale and scored from 0 to 3. In PSP, hypointensity score of red nucleus was higher than that in MSA-P (p = 0.001) and PD (p = 0.001), and a score of {>=}2 differentiated the PSP group from the PD and MSA-P groups. Putaminal hypointensity score was higher in PSP when compared to that in PD (p = 0.003), and a score of {>=}2 differentiated PSP from PD groups. SWI hypointensity scores of red nucleus and putamen had an excellent intrarater and interrater correlation. Substantia nigra hypointensity score of the PSP group was higher than that of the MSA-P (p = 0.004) and PD (p = 0.006) groups, but the scores had only a moderate intrarater and interrater correlation. SWI shows different patterns of brain mineralization in clinically diagnosed groups of PD, PSP, and MSA-P and may be considered as an additional MR protocol to help differentiate these conditions.

    Patients with coronary artery aneurysms (CAA) resulting from Kawasaki Disease (KD) are at risk for thrombosis and myocardial infarction. Current guidelines recommend using CAA diameter >8 mm as the criterion for initiating systemic anticoagulation, but there is little outcome data to support this choice. Transluminal Attenuation Gradient (TAG) has been proposed as a non-invasive method for evaluating the functional significance of coronary stenoses using CT Angiography (CTA). However TAG has ...

    Lamins A and C are nuclear intermediate filament proteins expressed in most differentiated somatic cells. Previous data suggested that prelamin A, the lamin A precursor, accumulates in some lipodystrophy syndromes caused by mutations in the lamin A/C gene, and binds and inactivates the sterol regulatory element binding protein 1 (SREBP1). Here we show that, in vitro, the tail regions of prelamin A, lamin A and lamin C bind a polypeptide of SREBP1. Such interactions also occur in HeLa cells, since expression of lamin tail regions impedes nucleolar accumulation of the SREBP1 polypeptide fused to a nucleolar localization signal sequence. In addition, the tail regions of A-type lamin variants that occur in Dunnigan-type familial partial lipodystrophy of (R482W) and Hutchison Gilford progeria syndrome ( Increment 607-656) bind to the SREBP1 polypeptide in vitro, and the corresponding FLAG-tagged full-length lamin variants co-immunoprecipitate the SREBP1 polypeptide in cells. Overexpression of wild-type A-type lamins and variants favors SREBP1 polypeptide localization at the intranuclear periphery, suggesting its sequestration. Our data support the hypothesis that variation of A-type lamin protein level and spatial organization, in particular due to disease-linked mutations, influences the sequestration of SREBP1 at the nuclear envelope and thus contributes to the regulation of SREBP1 function.

    Objective To investigate the course of coronary artery lesions caused by Kawasaki disease, and the value of coronary angiography (CAG) and two-dimensional echocardiograp hy (2-D Echo) in the evaluation and follow-up of coronary artery lesions. Methods Eighty seven patients with coronary artery lesions caused by Kawasaki disease fr om 1979 to 1997 were retrospectively analyzed. One hundred and sixty-seven CA Gs were performed in 87 patients during follow-up. CAG was repeated every 1- 3 years in each patient until complete regression was confirmed. 2-D Echo was performed before CAG each time. The longest period of follow-up was 16 years and 6 months. Patients were treated with aspirin or aspirin and warfarin. Results During follow-up, the coronary artery lesions regressed in 48/87 (55%) patients , however, they developed into severe coronary artery lesions in 6/87 (7%) patie nts in whom coronary artery bypass surgery was performed. The coronary artery aneurysm regressed in some patients, while stenotic lesions remained or develope d. The ratio of coronary artery stenotic lesions to aneurysms increased progre ssively. This study showed that Echo diagnosis of coronary artery lesions has "false positives" and "false negatives". Only 76% of coronary aneurysms and 18% of stenotic lesions could be found by 2-D Echo. No stenotic lesion could be found in distal segments of the coronary artery. Conclusions Long term follow up revealed spontaneous regression occurred in 55% of patients and development into severe coronary artery stenosis in 7%. It is necessary to perform long-term follow-up in patients with coronary artery lesions caused b y Kawasaki disease. 2-D Echo can not completely replace CAG during follow-up of coronary artery lesions caused by Kawasaki disease.%目的探讨川崎病后冠状动脉病变及转归,以及二维超声心动图和选择性冠状动脉造影在冠状动脉病变判断和长期随访中的作用.方法 1979-1997年因川崎病在治疗和随

    In recent years, the existence of visual variants of Alzheimer's disease characterized by atypical clinical presentation at onset has been increasingly recognized. In many of these cases post-mortem neuropathological assessment revealed that correlations could be established between clinical symptoms and the distribution of neurodegenerative lesions. We have analyzed a series of Alzheimer's disease patients presenting with prominent visual symptomatology as a cardinal sign of the disease. In these cases, a shift in the distribution of pathological lesions was observed such that the primary visual areas and certain visual association areas within the occipito-parieto-temporal junction and posterior cingulate cortex had very high densities of lesions, whereas the prefrontal cortex had fewer lesions than usually observed in Alzheimer's disease. Previous quantitative analyses have demonstrated that in Alzheimer's disease, primary sensory and motor cortical areas are less damaged than the multimodal association areas of the frontal and temporal lobes, as indicated by the laminar and regional distribution patterns of neurofibrillary tangles and senile plaques. The distribution of pathological lesions in the cerebral cortex of Alzheimer's disease cases with visual symptomatology revealed that specific visual association pathways were disrupted, whereas these particular connections are likely to be affected to a less severe degree in the more common form of Alzheimer's disease. These data suggest that in some cases with visual variants of Alzheimer's disease, the neurological symptomatology may be related to the loss of certain components of the cortical visual pathways, as reflected by the particular distribution of the neuropathological markers of the disease.

    Full Text Available El objetivo del presente estudio es presentar un caso clínico y revisar la literatura existente sobre el Síndrome de Kawasaki (SK tan frecuente en pacientes con necesidades especiales. Las características clínicas de esta patología se observan ya en niños muy jóvenes, en la gran mayoría de los casos menores de 5 años de edad. Esta es una patología que puede llevar al óbito, pues revela un compromiso cardíaco importante. Hay señales y síntomas en la cavidad oral en la fase aguda de la enfermedad, como la lengua de "frambuesa", eritema con fisura labial y eritema en la mucosa oral, siendo importante que el dentista tenga el conocimiento de esta patología y encamine el paciente para tratamiento médico con urgencia. Se observó en este caso una característica peculiar, que es la retención prolongada de la dentición temporaria. Una vez diagnosticado y tratado, el conocimiento del Síndrome de Kawasaki permite al dentista planear con seguridad un tratamiento dentario a largo plazo. Con eso puede evitarse que los dientes permanentes erupcionen ectópicamente, así como también mantener una profilaxis bucal de rutina, preservando la salud oral de los pacientes portadores de este síndrome.The aim of this study is to review what literature presents about Kawasaki Disease (KD, common in patients with special needs. Clinical evidence of this pathology may be observed in young children, who are usually less than five years old. This pathology may lead patients to death since it involves serious heart conditions. There are signs and symptoms in the oral cavity during the acute phase, for example "strawberry" tongue, red lesions with lips fissure and red lesions of oral mucous. Therefore it is important for the dentist to know about this pathology in order to send the patient to urgent medical treatment. A peculiar characteristic was observed in this case, long term retention of temporary dentition. Once the disease has been diagnosed and

    Full Text Available Introduction. Wilson's disease is typically manifested in two clinical forms, neurological and hepatic and in rare cases it starts with psychiatric symptoms exclusively. We presented a rare atypical case of Wilson's disease with psychotic onset. Case report. A 22-year-old male patient was initially presented with predominant signs and symptoms of psychiatric disorder and then later with the development of neurological signs and symptoms. Neuroimaging, detected metal deposits in central nervous system (CNS but not in peripheral organs, while serum analysis excluded pantothenate-kinase associated neurodegeneration (PKAN and aceruloplasminemia. In favor of the diagnosis of Wilson's disease there were reduced concentrations of copper and ceruloplasmin concentrations and metal deposits in CNS, but other pathognomonic signs and symptoms were absent: in-creased copper in urine, Kayser-Fleischer rings in Descemet’s corneal membrane and deposits of copper in liver. Introduction of penicillamine treatment resulted in improvement in mental and general health of the patient. Molecular genetic analysis definitely confirmed the diagnosis of Wilson's disease. Conclusion. Wilson's disease can remain undetected for a long period of time if masked with dominant or exclusive psychiatric symptoms. If clear clinical symptoms and signs, and unambiguous laboratory findings are not present, it is necessary to perform molecular genetic analysis to confirm the definitive diagnosis.

We thought that transpupillary thermotherapy (TTT utilizing a lower temperature than that of conventional laser photocoagulation might minimize permanent retinal and choroidal damage. Studies suggest that undesirable effects on vision due to TTT are minimal even if it is applied to foveal and/or parafoveal lesions when TTT requires a larger irradiation spot. The aim of this study was to evaluate the efficacy of TTT in the management of atypical CSC.Methods: We defined atypical CSC as bullous retinal detachment with diffuse or several leakages, severe leakage with fibrin formation under serous retinal detachment, or leakage within a pigment epithelium detachment. Eight consecutive patients with atypical CSC underwent visual acuity testing, ophthalmic examination, color photography, fluorescein angiography, and optical coherence tomography to evaluate the results of transpupillary thermotherapy. Retreatment of atypical CSC was based on ophthalmic examination, optical coherence tomography, and fluorescein angiography. TTT was performed on the leaking spots shown in fluorescein angiography, with a power of 50–250 mW, spot size of 500–1200 µm, and exposure time of 13–60 seconds to minimize retinal damage.Results: In five of eight affected eyes, serous detachments completely resolved within 1 month after the initial TTT. One eye had persistent subretinal fluid and required a second TTT treatment. Two eyes showed no resolution of CSC and were treated by conventional photocoagulation. Initial best-corrected visual acuity (BCVA ranged from 20/600 to 20/20 (mean, 20/40; median, 20/30. Final BCVA

    Full Text Available Introduction: Sickle cell anemia (SCA is the most severe form of sickle cell disease; it presents variants that are called haplotypes βS. There are five major haplotypes βS gene: Arab-Indian/Saudi, Senegal, Benin, Bantu, and Camaroon. Objective: Characterize the presence of haplotypes in patients with SCA in Amapá. Methods: 46 sample were studied, all samples were amplified and analyzed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP. Results: Bantu (61.2%, followed by Benin (26.5% and Senegal (12.2%. Conclusion: We identified three haplotypes characteristic of African ethnicity, with the presence of Senegal. In our study we found the presence of atypical haplotype, suggesting concentration and semi-isolation of the founding groups with little mixing.

  6. α-Synuclein and anti-α-synuclein antibodies in Parkinson's disease, atypical Parkinson syndromes, REM sleep behavior disorder, and healthy controls.

    Lynnae M Smith

    Full Text Available α-synuclein is thought to play a key role in Parkinson's disease (PD because it is the major protein in Lewy bodies, and because its gene mutations, duplication, and triplication are associated with early-onset PD. There are conflicting reports as to whether serum and plasma concentrations of α-synuclein and anti-α-synuclein antibodies differ between PD and control subjects. The objectives of this study were to compare the levels of α-synuclein and its antibodies between individuals with typical PD (n=14, atypical Parkinson syndromes (n=11, idiopathic rapid eye movement sleep behavior disorder (n=10, and healthy controls (n=9, to assess the strength of association between these serum proteins, and to determine group sizes needed for a high probability (80% power of detecting statistical significance for 25% or 50% differences between typical PD and control subjects for these measurements. Analysis of log-transformed data found no statistically significant differences between groups for either α-synuclein or its antibodies. The concentrations of these proteins were weakly correlated (Spearman rho=0.16. In subjects with typical PD and atypical Parkinson syndromes, anti-α-synuclein antibody levels above 1.5 µg/ml were detected only in subjects with no more than four years of clinical disease. Power analysis indicated that 236 and 73 samples per group would be required for an 80% probability that 25% and 50% differences, respectively, in mean α-synuclein levels between typical PD and control subjects would be statistically significant; for anti-α-synuclein antibodies, 283 and 87 samples per group would be required. Our findings are consistent with those previous studies which suggested that serum concentrations of α-synuclein and its antibodies are not significantly altered in PD.

    Rosai-Dorfman disease (sinus histiocytosis with massive lymphadenopathy, SHML) is a rare, non-hereditary, benign histiocytic proliferative disorder, presenting as painless bilateral cervical lymphadenopathy, with systemic symptoms. Extra nodal manifestations have been reported in 28-43 % cases with rare ocular involvement. We report a case of a 57 year old female presenting with gradual progressive decrease of vision OU since 8 months associated with epistaxis. Fundus examination revealed established optic atrophy in right eye with features of chronic papilloedema in left eye suggestive of compressive lesion. CT of brain, paranasal sinuses confirmed the presence of homogenously enhancing mass in left ethmoid sinus, left sphenoid sinus extending into suprasellar region. The biopsy of this mass revealed extra nodal SHML with tissue sections being S100 and CD68 positive with emperipolesis noted. Here we describe this atypical ocular presentation of extra nodal SHML to highlight that this rare disease can manifest as an aggressive sight threatening entity, even in older age group.

    The major mosquito vectors of human diseases have co-evolved with humans over a long period of time. However, the rapid growth in human population and the associated expansion in agricultural activity and greater urbanisation have created ecological changes that have had a marked impact on biology of mosquito vectors. Adaptation of the vectors of malaria and important arbovial diseases over a much shorter time scale to the new types of preimaginal habitats recently created by human population growth and activity is highlighted here in the context of its potential for increasing disease transmission rates. Possible measures that can reduce the effects on the transmission of mosquito-borne diseases are also outlined. PMID:27353577

    Eculizumab, terminal complement inhibitor, has become the frontline treatment for atypical hemolytic uremic syndrome (aHUS). However, the optimal treatment schedule has not yet been established. We describe here an aHUS patient with a mutation of C3 I1157T who achieved remission with eculizumab and suffered a recurrence after eculizumab discontinuation, a clinical situation that has not been previously described in patients with C3 mutation. A 9-year-old male experienced an onset of aHUS after viral gastroenteritis and was treated with hemodialysis. At 13 years of age he developed bacterial enterocolitis due to Campylobacter jejuni and experienced a recurrence of aHUS. Eculizumab was initiated on day 4 after disease onset resulting in recovering laboratory parameters. The patient received eculizumab for 5 months before its discontinuation. Second relapse induced by bacterial pharyngitis was confirmed 4 months after eculizumab discontinuation and prompt eculizumab reinitiation resulted in rapid remission. The patients carrying mutations in CFH or C3 have a high frequency of relapse and worse prognosis. More than 50% of aHUS relapses occurred during the first year after the onset. Therefore, long-term treatment with eculizumab is appropriate in patients with aHUS who have experienced a relapse or have mutations associated with poor prognosis. PMID:26840081

    We analytically study coarsening dynamics in a system with nonconserved scalar order parameter, when a uniform time-independent shear flow is present. We use an anisotropic version of the Ohta-Jasnow-Kawasaki approximation to calculate the growth exponents in two and three dimensions: for d=3 the exponents we find are the same as expected on the basis of simple scaling arguments, that is 3/2 in the flow direction and 1/2 in all the other directions, while for d=2 we find an unusual behavior, ...

    Many fungal and oomycete pathogens differentiate a feeding structure named the haustorium to extract nutrition from the plant epidermal cell.The atypical resistance (R) protein RPW8.2 activates salicylic acid (SA)-dependent,haustorium-targeted defenses against Golovinomyces spp.,the causal agents of powdery mildew diseases on multiple plant species.How RPW8.2 activates defense remains uncharacterized.Here,we report that RPW8.2 interacts with the phytochrome-associated protein phosphatase type 2C (PAPP2C) in yeast and in planta as evidenced by coimmunoprecipitation and bimolecular fluorescence complementation assays.Down-regulation of PAPP2C by RNA interference (RNAi) in Col-0 plants lacking RPW8.2 leads to leaf spontaneous cell death and enhanced disease resistance to powdery mildew via the SA-dependent signaling pathway.Moreover,down-regulation of PAPP2C by RNAi in the RPW8.2 background results in strong HR-like cell death,which correlates with elevated RPW8.2 expression.We further demonstrate that hemagglutinin (HA)-tagged PAPP2C prepared from tobacco leaf cells transiently transformed with HA-PAPP2C possesses phosphatase activity.In addition,silencing a rice gene (Os04g0452000) homologous to PAPP2C also results in spontaneous cell death in rice.Combined,our results suggest that RPW8.2 is functionally connected with PAPP2C and that PAPP2C negatively regulates SA-dependent basal defense against powdery mildew in Arabidopsis.

    Summary Background Previous case-control studies have suggested that the absence of a swallow-tail appearance in the substantia nigra on high-resolution SWI, representing nigrosome-1, has high accuracy to identify Parkinson’s disease (PD). The first goal of our study was to evaluate nigrosome-1 ex vivo using optimized high-resolution susceptibility sensitive MRI. Our second goal was to evaluate its diagnostic value in vivo using a clinical 3T SWI sequence to differentiate between PD and atypical parkinsonism (AP) in a cohort of patients with early-stage parkinsonism. Material/Methods Case-control pilot study to evaluate nigrosome-1 ex vivo (2 PD, 2 controls), using high-resolution susceptibility sensitive sequences at 11.7 T MRI. Next, evaluation of nigrosome-1 in vivo using a clinical 3 T SWI sequence in a prospective cohort of 60 patients with early-stage parkinsonism (39 PD, 21 AP). Moreover, 12 control subjects were scanned. The bilateral substantia nigra was evaluated by two neuroradiologists for the presence, absence or indecisive presence of nigrosome-1. The discriminative power was evaluated by Receiver-Operating Characteristic. Results We identified nigrosome-1 in ex vivo control subjects. Nigrosome-1 was not identified in the ex vivo PD cases. In our prospective clinical cohort study, the AUC for the swallow-tail sign to discriminate between PD and AP was 0.56 (0.41–0.71) for reader 1 and 0.68 (0.55–0.82) for reader 2. Conclusions The diagnostic accuracy of the swallow-tail sign was marginal to discriminate between PD and AP using our clinical 3 T SWI sequence.

    This study is the first report on the genetic and pathogenic characterization of beak and feather disease virus (BFDV) occurring in Italy. Twenty BFDV strains isolated in Italy from juvenile Congo African grey parrots (Psittacus erithacus) were investigated. Seventeen strains showed an "atypical peracute form" (aPF) of the disease, and three a chronic form (CF). The birds with aPF had been weaned, were independent as far as food and protection were concerned and apparently were without lesions. The gene coding for the putative coat protein was amplified in all isolates while the BFDV genome was sequenced completely in 10 samples, eight of them belonging to aPF affected birds and two from CF of the disease. All full genomes clustered into the J strain of BFDV, where two new subtypes were identified. Recombination analyses showed evidence of genetic exchanges in two BFDV genomes. In addition, a correlation between viral isolate and origin of the breeding material was shown, while an association between the genetic features of the virus and the clinical form was not observed. Histologically, apoptosis was detected frequently in aPF samples and sporadically in CF samples. Interestingly, BFDV antigens were detected in the nuclei and cytoplasm of such apoptotic cells. The data presented here support the hypothesis that, in the absence of a defined BFDV genetic variant accountable for a specific clinical form of psittacine beak and feather disease, differences in the apoptotic rate between aPF and CF are strictly host related.

Methods Serum level of ENA -78 and visfatin was measured in 90 children with KD and 30 healthy children by ELISA, and the outcome was estimated in combination with clinical symptoms. Results The serum levels of ENA -78 and visfatin in children with KD were significantly higher compared with that of the control group ( P < 0. 05 ); The serum levels of ENA - 78 and visfatin in children of KD with coronary artery lesion ( CAL ) were significantly higher compared with that of children of KD without CAL ( P < 0. 05 ). In children with KD, the serum levels of ENA -78 and visfatin had a positive correlation ( r = 0. 67, P < 0. 05 ). Conclusion Serum levels of ENA - 78 and visfatin are increased in the acute phase of KD, and are significantly higher in those KD children with CAL. ENA - 78 and visfatin may be used as an important serological indicator of KD with CAL.

    Meningococcal disease is the major health problem in developing world. The clinical presentation is varied, ranging from transient fever and bacteraemia to fulminant disease with death ensuing within hours of the onset of clinical symptoms. The classical clinical manifestations of meningococcal disease have been well described, but atypical presentations if unrecognized, may lead to a delay in treatment and fatal outcome. We here report a case presented with atypical presentation of meningococcal meningitis without classical rash, which was diagnosed and managed successfully.

    Full Text Available Abstract Background Kawasaki Syndrome (KS is an uncommon childhood disease with unknown etiology. It has been suggested that rotavirus infection may play a causative role in the development of KS. Methods To examine potential temporal associations between KS and rotavirus infection, seasonal patterns of KS- and rotavirus-associated hospitalizations among children in California and New York during 2000-2005 were compared. Results Rotavirus hospital admissions were markedly winter seasonal, with very few summer hospitalizations. KS hospitalizations occurred year-round but also peaked slightly during winter and spring. Conclusion The strong winter seasonal pattern of rotavirus clearly differed from the year-round pattern of KS hospitalizations. While the present study cannot completely rule out rotavirus as having a role in the development of KS, other agents must be involved in the etiology of KS.

    Orofacial pain' most commonly occurs due to dental causes like caries, gingivitis or periodontitis. Other common causes of 'orofacial pain' are sinusitis, temporomandibular joint(TMJ) dysfunction, otitis externa, tension headache and migraine. In some patients, the etiology of 'orofacial pain' remains undetected despite optimal evaluation. A few patients in the practice of clinical dentistry presents with dental pain without any identifiable dental etiology. Such patients are classified under the category of 'atypical odontalgia'. 'Atypical odontalgia' is reported to be prevalent in 2.1% of the individuals. 'Atypical orofacial pain' and 'atypical odontalgia' can result from the neurological diseases like multiple sclerosis, trigeminal neuralgia and herpes infection. Trigeminal neuralgia has been frequently documented as a cause of 'atypical orofacial pain' and 'atypical odontalgia'. There are a few isolated case reports of acute pontine stroke resulting in 'atypical orofacial pain' and 'atypical odontalgia'. However, pontine stroke as a cause of atypical odontalgia is limited to only a few cases, hence prevalence is not established. This case is one, where a patient presented with acute onset atypical dental pain with no identifiable dental etiology, further diagnosed as an acute pontine infarct on neuroimaging. A 40 years old male presented with acute onset, diffuse teeth pain on right side. Dental examination was normal. Magnetic resonance imaging(MRI) of the brain had an acute infarct in right pons near the trigeminal root entry zone(REZ). Pontine infarct presenting with dental pain as a manifestation of trigeminal neuropathy, has rarely been reported previously. This stresses on the importance of neuroradiology in evaluation of atypical cases of dental pain. PMID:26464604

    ObjectiveTo assess the values of 320-detector row dynamic volume CT angiography (CTA) and transthoracic echocardiography (TTE) in follow up of coronary artery aneurysm (CAA) caused by Kawasaki disease (KD).Methods320-de-tector row CTA and TTE were applied in long-term follow-up of 8 patients with CAA caused by KD.ResultsIn 8 patients, the mean age at onset was 41.63±22.70 months and the mean follow up time was 43.50±10.99 months. In acute phase, 3 cases of giant coronary artery aneurysms (GCAA) and 5 cases of mid-small CAA were diagnosed by TTE. A total of 16/32 arteries (50%) were involved. At the end of follow-up, 3 cases of GCAA and 2 cases of mid-small CAA were still diagnosed by TTE, and small CAAs were regressed in another 3 cases. A total of 6/32 arteries (18.75%) were involved. Simultaneously at the end of follow-up, a total of 7/32 arteries (21.9%) were involved by 320-detector row CTA. The distribution was consistent with that of TTE. Mean-while, there were one case of left circumlfex artery, one case of GCAA at distal of the right coronary artery, 2 cases of thrombus, 1 case of coronary stenosis and 2 cases of calciifcation.ConclusionsCAA caused by KD may be persistent for a long time. The thrombus, stenosis, and calciifcation of coronary can occurr at late phase in GCAA. TTE is sensitive and reliable to detect proxi-mal and middle segment of coronary lesions, but has limitations in detection of distal segment of coronary arteries. 320-detector row CTA has more comprehensively view of each coronary artery lesions and is especially sensitive and reliable to detect coro-nary thrombosis, calciifcation and narrowing in proximal and distal coronary arteries after acute phase.%目的:探讨320排动态容积CT冠状动脉成像(CTA)及经胸超声心动图(TTE)对川崎病(KD)合并冠状动脉瘤(CAA)中远期随访的应用价值。方法采用320排CTA、TTE进行中远期追踪随访8例KD合并CAA患儿。结果8例患儿平均发病年龄(41.63±22

    Full Text Available Dengue fever is affecting millions of population globally. For the past one decade, we have seen several outbreaks and even causing significant mortality of affected population. We witnessed numerous pattern and multisystem presentation of dengue in this period. The CNS manifestation like encephalitis, polyneuropathy (GB like syndrome and paresthesias were uncommonly reported priorly. Pancreatitis, polyserositis, carditis of varying severity and hepatic failure are the, some of atypical manifestations observed in recent out breaks. So dengue illness can presents with multi system involvement and can account to significant mortality. Here an attempt was done to present varying, uncommon and atypical manifestation of dengue illness. [Int J Res Med Sci 2014; 2(4.000: 1804-1806

    2012-01-01

    AIS hypothesis has the right to recognition, if it explains the transition of "healthy" vertebra column into status of "scoliotic" one. AIS is the most investigated disease in the history of orthopedics, but up the present time there is no clear explanation of some its phenomena: vertebra column mono-form deformation along with its poly etiology character, interrelation of its origin and development and child's growth process etc. The key for authors' view at AIS was scoliosis with non-standard (concave side) rotation. On the bases of its' multifunctional instrumental investigation results (Rtg, EMG, EEG, optical topography, hormonal and neuropeptides trials, thermo-vision methods and other) in comparison with typical AIS was worked out the new hypothesis, part of it is suggested for discussion. In the work under observation is the sequence of appearance of typical and atypical scoliosis symptomatology beginning from the preclinical stage. PMID:22744477

    We analytically study coarsening dynamics in a system with nonconserved scalar order parameter, when a uniform time-independent shear flow is present. We use an anisotropic version of the Ohta-Jasnow-Kawasaki approximation to calculate the growth exponents in two and three dimensions: for d=3 the exponents we find are the same as expected on the basis of simple scaling arguments, that is, 3/2 in the flow direction and 1/2 in all the other directions, while for d=2 we find an unusual behavior, in that the domains experience an unlimited narrowing for very large times and a nontrivial dynamical scaling appears. In addition, we consider the case where an oscillatory shear is applied to a two-dimensional system, finding in this case a standard t(1/2) growth, modulated by periodic oscillations. We support our two-dimensional results by means of numerical simulations and we propose to test our predictions by experiments on twisted nematic liquid crystals. PMID:11089010

    We generalize Kawasaki's dynamics, spin-pair exchange mechanism, to a spin-pair redistribution mechanism,and we present a normalized redistribution probability. As an application, we treat the one-dimensional kinetic Gaussian model and obtain the exact diffusion equation and the temperature-dependent diffusion coefficient. We find that the diffusion process can slow down infinitely near the critical point and obtain the critical dynamic exponent z = 2 that is independent of the assumed mechanism, either Glauber-type or Kawasaki-type.

    Occurrence of eclampsia before 20 weeks of pregnancy and after 48 hours of delivery in the absence of typical signs of hypertension and or proteinuria is termed as atypical eclampsia. Atypical or non-classic eclampsia will have some symptoms of eclampsia but without the usual proteinuria or hypertension. All patients with atypical onset should undergo neurological evaluation to rule out neurologic causes of seizures. Cerebral tuberculosis is a rare and serious form of disease secondary to haematogenous spread of Mycobacterium tuberculosis. Here we present a case of cerebral tuberculoma with seizures in late pregnancy mimicking eclampsia. PMID:27504359

    2015-09-01

    Preeclampsia is a pregnancy-related syndrome, which still represents one of the major causes of maternal-fetal mortality and morbidity. Diagnosis can be made difficult due to the complexity of the disorder and its wide spectrum of clinical manifestations. In order to provide an efficient diagnostic tool to the clinician, medical societies regularly rethink the definition criteria. However, there are still clinical presentations of preeclampsia that escape the frame of the definition. The present review will address atypical forms of preeclampsia, such as preeclampsia without proteinuria, normotensive preeclampsia, preeclampsia before 20 weeks of gestation and post-partum preeclampsia.

Rubric “atypical depression” includes a variety of depressive states characterized by reactively caused changes of mood, sensitivity to interpersonal contacts, inverted vegetative and somatic symptoms such as increased appetite and hypersomnia. The article considers the place of atypical depression in the structure of organic mental disorders. Positions of foreign authors that produce atypical depression as a clinical entity in the structure of Bipolar affective disorder II type are represented, the views of other authors on the structure of atypical depression are considered. The analysis of national concept of non-circular depression is carried out. Questions of atypical affective conditions acquire special significance due to preparation of International Classification of Diseases of the 11th revision, because inclusion in it of Bipolar affective disorder II type, a manifestation of which is considered to be atypical depressions, is under discussion.

    2016-01-01

    Full Text Available Dermatofibroma is a common benign fibrohistiocytic tumor and its diagnosis is easy when it presents classical clinicopathological features. However, a dermatofibroma may show a wide variety of clinicopathological variants and, therefore, the diagnosis may be difficult. The typical dermatofibroma generally occurs as a single or multiple firm reddish-brown nodules. We report here two atypical presentations of dermatofibroma - Atrophic dermatofibroma and keloidal presentation of dermatofibroma. Clinical dermal atrophy is a common phenomenon in dermatofibromas as demonstrated by the dimpling on lateral pressure. However, this feature is exaggerated in the atrophic variant of dermatofibroma. Atrophic dermatofibroma is defined by dermal atrophy of more than 50% of the lesion apart from the usual features of common dermatofibroma. The keloidal variant of dermatofibroma should not be overlooked as a simple keloid. The findings of keloidal change in dermatofibromas may support that trauma is a possible cause of dermatofibroma.

    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of central nervous system classically characterized by acute, severe episodes of optic neuritis and longitudinally extensive transverse myelitis, usually with a relapsing course. The identification of an autoantibody exclusively detected in NMO patients against aquaporin-4 (AQP-4 has allowed identification of cases beyond the classical phenotype. Brain lesions, once thought as infrequent, can be observed in NMO patients, but lesions have different characteristics from the ones seen in multiple sclerosis. Additionally, some AQP-4 antibody positive patients may present with a variety of symptoms not being restricted to optic neuritis and acute myelitis during the first attack or in a relapse. Examples are not limited to, but may include patients only with brain and/or brainstem lesions, narcolepsy with hypothalamic lesions or patients with intractable hiccups, nausea and vomiting. The prompt identification of NMO patients with atypical presentations may benefit these patients with institution of early treatment to reduce disability and prevent further attacks.

    Alzheimer`s disease (AD) is a progressive, degenerative neurological disorder of the central nervous system. AD is the fourth leading cause of death in elderly persons 65 years or older in Western industrialized societies. The etiology of AD is unknown, but clinical, pathological, epidemiological, and molecular investigations suggest it is etiologically heterogeneous. Mutations in the amyloid protein are rare and segregate with the disease in a few early-onset familial AD (FAD) families. Similarities between AD and the unconventional viral (UCV) diseases, and between the amyloid and prion proteins, implicate the human prion protein gene (PRNP) as another candidate gene. Single strand conformation polymorphism (SSCP) analysis was used to screen for mutations at this locus in 82 AD patients from 54 families (30 FAD), vs. 39 age-matched controls. A 24-bp deletion around codon 68 that codes for one of five Gly-Pro rich octarepeats was identified in two affected sibs and one offspring of one late-onset FAD family. Two other affected sibs, three unaffected sibs, and three offspring from this family, in addition to one sporadic AD patient and three age-matched controls, were heterozygous for another octarepeat deletion located around codon 82. Two of the four affected sibs had features of PD, including one who was autopsy-verified AD and PD. Although these deletions were found infrequently in other AD patients and controls, they appear to be a rare polymorphism that is segregating in this FAD family. It does not appear that mutations at the PRNP locus are frequently associated with AD in this population. 54 refs., 4 figs.

    2011-01-01

    Full Text Available We describe here a rare case of variant of mycosis fungoides (MF: ichthyosiform MF with alopecia and atypical membranous nephropathy. The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

  18. Atypical moles: diagnosis and management.

    Perkins, Allen; Duffy, R Lamar

    2015-06-01

    Atypical moles are benign pigmented lesions. Although they are benign, they exhibit some of the clinical and histologic features of malignant melanoma. They are more common in fair-skinned individuals and in those with high sun exposure. Atypical moles are characterized by size of 6 mm or more at the greatest dimension, color variegation, border irregularity, and pebbled texture. They are associated with an increased risk of melanoma, warranting enhanced surveillance, especially in patients with more than 50 moles and a family history of melanoma. Because an individual lesion is unlikely to display malignant transformation, biopsy of all atypical moles is neither clinically beneficial nor cost-effective. The ABCDE (asymmetry, border irregularity, color unevenness, diameter of 6 mm or more, evolution) mnemonic is a valuable tool for clinicians and patients to identify lesions that could be melanoma. Also, according to the "ugly duckling" concept, benign moles tend to have a similar appearance, whereas an outlier with a different appearance is more likely to be undergoing malignant change. Atypical moles with changes suggestive of malignant melanoma should be biopsied, using an excisional method, if possible.

  19. Recognition and diagnosis of atypical depression.

    Science.gov (United States)

    Thase, Michael E

    2007-01-01

    The term atypical depression dates to the first wave of reports describing differential response to monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). In contrast to more TCA-responsive depressions, patients with so-called atypical symptoms (e.g., hypersomnia, interpersonal sensitivity, leaden paralysis, increased appetite and/or weight, and phobic anxiety) were observed to be more responsive to MAOIs. After several decades of controversy and debate, the phrase "with atypical features" was added as an episode specifier in the DSM-IV in 1994. The 1-year prevalence of the defined atypical depression subtype is approximately 1% to 4%; around 15% to 29% of patients with major depressive disorder have atypical depression. Hardly "atypical" in contemporary contexts, atypical depression also is common in dysthymic bipolar II disorders and is notable for its early age at onset, more chronic course, and high rates of comorbidity with social phobia and panic disorder with agoraphobia. The requirement of preserved mood reactivity is arguably the most controversial of the DSM-IV criteria for atypical depression. When compared with melancholia, the neurobiological profiles of patients with atypical depression are relatively normal. The utility of the atypical depression subtype for differential therapeutics diminished substantially when the TCAs were supplanted as first-line antidepressants by the selective serotonin reuptake inhibitors. Although introduction of safer MAOIs has fostered renewed interest in atypical depression, the validity and importance of the DSM-IV definition of atypical depression for the nosology of affective illness remains an open question.

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

  11. Atypical fractures, a biased perspective.

    Science.gov (United States)

    Aspenberg, Per

    2016-01-01

    When stress fractures started to show up in the femurs of elderly ladies, it was soon evident that bisphosphonate use lay behind, and the absolute risk increase due to bisphosphonate use was reasonably well estimated already in 2008. Thereafter followed a period of confusion: the term atypical fracture was introduced, with a definition so vague that the true stress fractures tended to disappear in a cloud of ambiguity. This cast doubt on the association with bisphosphonates. The association was then re-established by large epidemiological studies based on radiographic adjudication. Atypical fractures are largely caused by bisphosphonates. With a correct indication, bisphosphonates prevent many more fractures than they cause, at least during the first years of use. With an incorrect indication they are likely to cause more harm than good. PMID:26768286

  14. Damage spreading on the 3-12 lattice with competing Glauber and Kawasaki dynamics

    Z Z Guo; Xiao-Wei Wu; Chun-An Wang

    2006-06-01

    The damage spreading of the Ising model on the 3-12 lattice with competing Glauber and Kawasaki dynamics is studied. The difference between the two kinds of nearest-neighboring spin interactions (interaction between two 12-gons, or interaction between a 12-gon and a triangle) are considered in the Hamiltonian. It is shown that the ratio of the interaction strength between the two kinds of interactions plays an important role in determining the critical temperature d of phase transition from frozen to chaotic. Two methods are used to introduce the bond dilution on the Ising model on the 3-12 lattice: regular and random. The maximum of the average damage spreading $\\langle D \\rangle_{\\text{max}}$ can approach values lower than 0.5 in both cases and the reason can be attributed to the `survivors' among the spins. We have also, for the first time, presented the phase diagram of the mixed G–K dynamics in the 3-12 lattice which shows what happens when going from pure Glauber to pure Kawasaki.

  15. Case Report: Atypical Cornelia de Lange Syndrome.

    Leanza, Vito; Rubbino, Gabriella; Leanza, Gianluca

    2014-01-01

    Cornelia de Lange Syndrome (CdLS) (also called Bushy Syndrome or Amsterdam dwarfism), is a genetic disorder that can lead to several alterations. This disease affects both physical and neuropsychiatric development. The various abnormalities include facial dysmorphia (arched eyebrows, synophrys, depressed nasal bridge, long philtrum, down-turned angles of the mouth), upper-extremity malformations, hirsutism, cardiac defects, and gastrointestinal alterations. The prevalence of this syndrome is approximately one per 15,000. Ultrasound is not the perfect means to diagnose CdLS, however, many abnormalities can be detected prenatally by scrupulous image observation. We report an atypical CdLS case characterized by increased nuchal translucency in the first trimester, normal karyotype, saddle nose, micrognathia with receding jaw, low set ears, facies senilis, arthrogryposis of the hands, absence of the Aranzio ductus venous, dilatation of gallbladder and bowel, a unique umbilical artery, increased volume of amniotic fluid, and intrauterine growth retardation ending with the interruption of pregnancy.

  16. Atypical scrapie isolates involve a uniform prion species with a complex molecular signature.

    Directory of Open Access Journals (Sweden)

    Dorothea R Götte

    Full Text Available The pathobiology of atypical scrapie, a prion disease affecting sheep and goats, is still poorly understood. In a previous study, we demonstrated that atypical scrapie affecting small ruminants in Switzerland differs in the neuroanatomical distribution of the pathological prion protein (PrP(d. To investigate whether these differences depend on host-related vs. pathogen-related factors, we transmitted atypical scrapie to transgenic mice over-expressing the ovine prion protein (tg338. The clinical, neuropathological, and molecular phenotype of tg338 mice is similar between mice carrying the Swiss atypical scrapie isolates and the Nor98, an atypical scrapie isolate from Norway. Together with published data, our results suggest that atypical scrapie is caused by a uniform type of prion, and that the observed phenotypic differences in small ruminants are likely host-dependant. Strikingly, by using a refined SDS-PAGE technique, we established that the prominent proteinase K-resistant prion protein fragment in atypical scrapie consists of two separate, unglycosylated peptides with molecular masses of roughly 5 and 8 kDa. These findings show similarities to those for other prion diseases in animals and humans, and lay the groundwork for future comparative research.

  17. Evolving A-Type Artificial Neural Networks

    2011-01-01

    We investigate Turing's notion of an A-type artificial neural network. We study a refinement of Turing's original idea, motivated by work of Teuscher, Bull, Preen and Copeland. Our A-types can process binary data by accepting and outputting sequences of binary vectors; hence we can associate a function to an A-type, and we say the A-type {\\em represents} the function. There are two modes of data processing: clamped and sequential. We describe an evolutionary algorithm, involving graph-theoretic manipulations of A-types, which searches for A-types representing a given function. The algorithm uses both mutation and crossover operators. We implemented the algorithm and applied it to three benchmark tasks. We found that the algorithm performed much better than a random search. For two out of the three tasks, the algorithm with crossover performed better than a mutation-only version.

Studies have demonstrated that PSP can present clinically as an atypical dementing syndrome dominated by a progressive apraxia of speech (AOS and aphasia. Aim: We aimed to investigate the clinical presentation of PSP, using a comprehensive multidimensional evaluation, and the disease response to various pharmacological treatments. Methods: A 72-year-old right-handed male, with 17 years education, who first presented with aphasia, AOS, depression, apathy, and postural instability at 69 years; a complete neuropsychological evaluation, tapping the different cognitive domains, was performed. Results: Testing revealed a moderate global cognitive deficit (Mini-Mental State Examination test score =20, low memory test scores (story recall, Rey’s 15-word Immediate and Delayed Recall, and poor phonemic and semantic fluency. The patient’s language was characterized by AOS, with slow speech rate, prolonged intervals between syllables and words, decreased articulatory accuracy, sound distortions, and anomia. Behavioral changes, such as depression, anxiety, apathy, and irritability, were reported. The neurological examination revealed supranuclear vertical gaze palsy, poor face miming, and a mild balance deficit. Magnetic resonance imaging showed only widespread cortical atrophy. Single photon emission computed tomography demonstrated left > right frontotemporal cortical abnormalities. After 6 months, a further neuropsychological assessment showed a progression in cognitive deficits, with additional attention deficits. The patient reported frequent falls, but the neurological deficits remained unchanged. Neuroimaging tests showed the same brain involvement.

    Full Text Available Sporotrichosis occurs after fungal implantation of Sporothrix spp. in the skin, and is the main subcutaneous mycosis in Latin America. Here we describe three atypical cases of the disease. The first case report an extra-cutaneous occurrence of the disease with joint infection; the second one describes a patient with bilateral lymphocutaneous form of sporotrichosis; and the third shows a zoonotic cutaneous case with the development of an erythema nodosum as a hypersensitivity reaction. These cases show the disease importance on the region and the necessity of fungal culture to the diagnosis confirmation.

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    Full Text Available Aim: To review the experience with the diagnosis and management of extragonadal germ cell tumors (GCT with a subset analysis of those with atypical features. Materials and Methods: A retrospective chart review of patients of extragonadal germ cell tumors between 2000 and 2010 was carried out. Results: Fifteen children aged 7 days to 15 years (median, 1.5 years were included. Three had an antenatal diagnosis (one sacrococcygeal, one retrobulbar, one retroperitoneal tumor and were operated in the neonatal period. The locations were distributed between the retrobulbar area (1, anterior neck-thyroid gland (1, mediastinum (4, abdominothoracic extending through the esophageal hiatus (1, retroperitoneal (4 and sacrococcygeal (4. On histological examination, five harbored immature elements while two were malignant; the latter children received postexcision adjuvant chemotherapy. There was no mortality. At a median follow-up of 4.5 years (6 months to 8 years, 14/15 have had an event-free survival. One immature mediastinal teratoma that recurred locally 7.5 years after the initial operation was excised and adjuvant chemotherapy instituted. Conclusions: Extragonadal GCTs in children are uncommon and occasionally present with atypical clinical, radiological and histological features resulting in diagnostic and therapeutic dilemmas.

    2013-09-01

    Full Text Available Introduction: Vestibular schwannoma (also known as acoustic neuroma is a benign tumor whose cells are derived from Schwann sheaths, which commonly occurs from the vestibular portion of the eighth cranial nerve. Furthermore, vestibular schwannomas account for ∼8% of intracranial tumors in adults and 80 to 90% of tumors of the cerebellopontine angle. Its symptoms are varied, but what stands out most is a unilateral sensorineural hearing loss, with a low index of speech recognition. Objective: Describe an atypical manifestation of vestibular schwannoma. Case Report: The 46-year-old woman had vertigo and binaural hearing loss and fullness, with ear, nose, and throat examination suggestive of cochlear injury. After 6 months, the patient developed worsening of symptoms and onset of right unilateral tinnitus. In further exams the signs of cochlear damage remained, except for the vestibular test (hyporeflexia. Magnetic resonance imaging showed an expansive lesion in the right cerebellopontine angle. Discussion: This report warns about the atypical manifestations of vestibular schwannoma, which must always be remembered in investigating and diagnosing hearing loss.

  6. On the convergence of the Ohta-Kawasaki Equation to motion by nonlocal Mullins-Sekerka Law

    CERN Document Server

    Le, Nam Q

    2009-01-01

    In this paper, we establish the convergence of the Ohta-Kawasaki equation to motion by nonlocal Mullins-Sekerka law on any smooth domain in space dimensions $N\\leq 3$. These equations arise in modeling microphase separation in diblock copolymers. The only assumptions that guarantee our convergence result are $(i)$ well-preparedness of the initial data and $(ii)$ smoothness of the limiting interface. Our method makes use of the "Gamma-convergence" of gradient flows scheme initiated by Sandier and Serfaty and the constancy of multiplicity of the limiting interface due to its smoothness. For the case of radially symmetric initial data without well-preparedness, we give a new and short proof of the result of M. Henry for all space dimensions. Finally, we establish transport estimates for solutions of the Ohta-Kawasaki equation characterizing their transport mechanism.

  7. Atypical p-ANCA in PSC and AIH: a hint toward a "leaky gut"?

    Terjung, Birgit; Spengler, Ulrich

    2009-02-01

    Primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) are enigmatic chronic inflammatory diseases of the liver, which are frequently associated with chronic inflammatory bowel diseases. Both types of liver disease share various distinct autoantibodies such as atypical perinuclear antineutrophil cytoplasmic antibodies (p-ANCA), and thus are considered autoimmune disorders with atypical features. The discovery that atypical p-ANCA recognize both tubulin beta isoform 5 in human neutrophils and the bacterial cell division protein FtsZ has renewed the discussion on the potential role of microorganisms in the pathogenesis of both diseases. In this paper, we review the evidence for microbial infection in PSC and AIH and discuss new concepts how cross-recognition between microbial antigens in the gut and host components by the immune system along with stimulation of pattern recognition receptors might give rise to chronic hepatic inflammatory disorders with features of autoimmunity.

    Thrombotic microangiopathies (TMA) such as atypical hemolytic uremic syndrome (aHUS) have evolved from rare, fulminant childhood afflictions to uncommon diseases with acute and chronic phases involving both children and adults. Breakthroughs in complement and coagulation regulation have allowed redefinition of specific entities despite substantial phenotypic mimicry. Reconciliation of phenotypes and delivery of life saving therapies require a multidisciplinary team of experts. The purpose of this review is to describe advances in the molecular pathophysiology of aHUS and to share the 2014 experience of the multidisciplinary Johns Hopkins TMA Registry in applying diagnostic assays, reporting disease associations, and genetic testing.

    A 14 year old patient with short stature, type I diabetes, and cataracts was referred for evaluation of avascular necrosis of the femoral head. Radiography was suggestive of spondyloepiphyseal dysplasia with decreased bone mineral density for age. Targeted molecular and biochemical testing were normal in this patient. Whole exome sequencing was performed and showed compound heterozygosity for previously reported pathogenic GALNS variants which were diagnostic of mucopolysaccharidosis, type IVA (Morquio A). While this case describes neither a novel condition nor a new mutation, it does illustrate three important points in the diagnosis of patients with atypical forms of MPS IVA. First, that in many instances urine glycosaminoglycan analysis is not sufficient to rule out MPS IVA as a potential diagnosis. Patients in whom biochemical screening is advised should have measurement of leukocyte enzymatic activity. Second, that in patients with radiographic evidence of spondyloepiphyseal dysplasia with additional features or with normal targeted testing, MPS IVA should remain in the differential diagnosis. Third, that whole exome sequencing represents a viable diagnostic platform for evaluation of patients with unknown skeletal or metabolic disease.

    Although nocturnal disturbances are increasingly recognized as an integral part of the continuum of daytime manifestations of Parkinson's disease (PD), there is still little evidence in the medical literature to support the occurrence of these complex phenomena in patients with atypical parkinsonian disorders (APDs). Based on the anatomical substrates in APDs, which are considered to be more extensive outside the basal ganglia than in PD, we might expect that patients with APDs encounter the whole range of nocturnal disturbances, including motor, sleep disorders, autonomic dysfunctions, and neuropsychiatric manifestations at a similar, or even greater, frequency than in PD. This article is a review of the current literature on the problems at nighttime of patients with progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, and dementia with Lewy bodies. MEDLINE, life science journals and online books were searched by querying appropriate key words. Reports were included if the studies were related to nocturnal manifestations in APDs. Forty articles fulfilled the selection criteria. Differences between these symptoms in APDs and PD are highlighted, given the evidence available about each manifestation. This analysis of nocturnal manifestations of APDs suggests the need for future studies to address these issues to improve the quality of life not only of patients with APDs but the caregivers who encounter the challenges of supporting these patients on a daily basis.

    Full Text Available ObjectiveGuillain-Barre syndrome (GBS is an immune-mediated polyneuropathy that occurs mostly after prior infection. The diagnosis of this syndrome is dependent heavily on the history and examination, although cerebrospinal fluid analysis and electrodiagnostic testing usually confirm the diagnosis. This is a retrospective study which was performed to investigate the atypical features of GBS.Materials & MethodsThirty three patients (21/63.6% males and 12/36.4% females with GBS were retrospectively studied and prospectively evaluated at the Child Neurology institute of Mofid Children Hospital of Shahid Beheshti University of Medical Sciences between May 2011 and September 2012.ResultsThe mean age was 5.4 years (range, 1.5-10.5.Twenty one patients (87.9 % had previous history of infections.

    Frontotemporal dementia (FTD) is a debilitating disease that is well described in the "Diagnostic and statistical manual of mental disorders, fifth edition (DSM-5)", and typically presents with memory impairment, progressive decline in cortical functioning, and behavioral changes. Age of onset is generally in the late fifties, and usually the first presentation involves a change in behavior and emotional blunting. Treatment of FTD involves management of any neurobehavioral symptoms while trials of atypical antipsychotics are ongoing but suggest some efficacy. We present a case of a patient who first presented with severe paranoid personality traits and frank persecutory delusions. This atypical presentation of our patient first led to her incorrect diagnosis of a psychotic disorder and paranoid personality disorder. As a result of this diagnosis, she was treated unsuccessfully. A subsequent magnetic resonance imaging (MRI) then showed atrophy of frontal and temporal lobes bilaterally (left more prominent than right) which confirmed the diagnosis of FTD. The importance of this case involves the atypical presentation of paranoia and delusions, and our patient's incorrect diagnosis based on her clinical presentation led to a trial of unsuccessful treatment. Only after performing an MRI, which showed atrophy, was the patient appropriately treated and deemed medically stable. This case report illustrates the importance of considering a rare presentation of frontotemporal lobe dementia with patients who are in the typical age range and present with paranoia and delusions.

    2016-05-01

    The histologic features and outcome of 58 cases of epithelioid schwannoma were studied to determine the significance of atypical histologic features. Cases were retrieved from personal consultation files from 1999 to 2013. Patients (31 male and 26 female patients) ranged in age from 14 to 80 years (median, 38 y). Two patients had schwannomatosis 1. Tumors developed in the dermis/subcutis (n=56) or muscle (n=2) of the upper extremity (34.5%), lower extremity (34.5%), thorax/abdomen/back (18%), and less common anatomic locations including the scalp, neck, lip, and breast. They ranged in size from 0.25 to 4.5 cm (median, 2.0 cm). Typically circumscribed and surrounded by a perineurium, they comprised single or small groups of epithelioid schwann cells with a moderate amphophilic cytoplasm and occasional nuclear pseudoinclusions. Stroma varied from myxoid to hyalinized, often with thick-walled vessels (55 cases). Mitotic rate ranged from 0 to 9 mitoses/10 high-power field (HPF) (2.37 mm) in the most active areas (mean, 2 to 3 mitoses/10 HPFs). Thirteen cases (22%) were "atypical," defined by a high mitotic rate (≥3 mitoses per 10 HPFs) and nuclear size variation (≥3:1). All (56/56) expressed S100 protein; type IV collagen invested groups or individual cells (16/17). Melanoma markers were negative, except for melan A (1 case). Follow-up in 39 patients (median, 78 mo; range, 6 to 174 mo) indicated that 31 (79%) were alive without disease (including 9/13 atypical cases; median, 78 mo), 7 (18%) were alive with unknown status, and 1 patient had died of unrelated causes. One tumor recurred, but none metastasized. Epithelioid schwannomas, even those with atypical features, are benign and do not constitute a histologic continuum with epithelioid malignant peripheral nerve sheath tumors, which typically occur in deep soft tissues and have more anaplastic features.

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    Atypical neuropathic facial pain is a syndrome of intractable and unremitting facial pain that is secondary to nociceptive signaling in the trigeminal system. These syndromes are often recalcitrant to pharmacotherapy and other common interventions, including microvascular decompression and percutaneous procedures. Herein, the authors present two other viable approaches (nucleus caudalis dorsal root entry zone lesioning and motor cortex stimulation), their indications, and finally a possible treatment algorithm to consider when assessing patients with atypical facial pain.

    Diameters of coronary artery aneurysms (CAAs) complicating acute phase KD can strongly predict the long-term prognosis of coronary artery lesions (CAL). Recently, computed tomographic angiography (CTA) has been used to detect CAL, and the purpose of this study was to determine whether coronary artery diameters measurements by CTA using dual-source computed tomography (DSCT) can be used instead of coronary angiogram (CAG) measurements. Twenty-five patients (22 males and three females) with CAL due to KD, who had undergone both CTA and CAG within one year, were retrospectively evaluated between 2007 and 2013. A prospective electrocardiogram-triggered CTA was performed on a DSCT (SOMATOM(®) Definition, Siemens Healthcare, Germany). Two pediatric cardiologists independently measured the diameters of CAAs twice in each maximum intensity projection (MIP), curved multiplaner reconstruction (MPR) and CAG. We measured 161 segments in total (segment 1-3, 5-7, 11, 13). Diagnostic accuracy was expressed as κ coefficient. A Bland-Altman analysis was also used to assess the intra-observer, inter-observer and inter-modality agreement. The diagnostic quality of CTA was excellent (κ = 0.93). Excellent inter-observer agreement for the diameters of CAAs was obtained for MIP, MPR and CAG and for the intra-observer agreement. The inter-modality agreement was also excellent in measurements of CAA (MPR-CAG: y = 0.9x + 0.40, r = 0.97, p < 0.0001 MIP-CAG: y = x + 0.1, r = 0.94, p < 0.0001). These values in normal coronary arteries were also obtained. We found a significant correlation between CTA and CAG in measuring the coronary arteries. We conclude that measuring coronary artery diameters by CTA is reliable and useful. PMID:26515298

    2011-01-01

    This is the second in a series of three papers in which we study a two-dimensional lattice gas consisting of two types of particles subject to Kawasaki dynamics at low temperature in a large finite box with an open boundary. Each pair of particles occupying neighboring sites has a negative binding energy provided their types are different, while each particle has a positive activation energy that depends on its type. There is no binding energy between particles of the same type. At the boundary of the box particles are created and annihilated in a way that represents the presence of an infinite gas reservoir. We start the dynamics from the empty box and are interested in the transition time to the full box. This transition is triggered by a critical droplet appearing somewhere in the box. In the first paper we identified the parameter range for which the system is metastable, showed that the first entrance distribution on the set of critical droplets is uniform, computed the expected transition time up to and...

    The majority of dengue viral infections are asymptomatic, though symptoms may range from self-limiting febrile illness to life threatening hemorrhagic manifestations. As the burden of disease is dramatically rising in recent years, more patients with atypical presentations and rare complications are increasingly reported. Dengue virus may rarely involve different organ systems including CNS, liver, and heart. However, involvement of eye and thyroid is extremely rare. We present a case of 32-year old patient who presented with conjunctivitis and subacute thyroiditis and was found to have dengue viral infection as the cause of these conditions. PMID:27376214

  2. Archival search for historical atypical scrapie in sheep reveals evidence for mixed infections.

    Natural scrapie in sheep occurs in classical and atypical forms, which may be distinguished on the basis of the associated neuropathology and properties of the disease-associated prion protein on Western blots. First detected in 1998, atypical scrapie is known to have occurred in UK sheep since the 1980s. However, its aetiology remains unclear and it is often considered as a sporadic, non-contagious disease unlike classical scrapie which is naturally transmissible. Although atypical scrapie tends to occur in sheep of prion protein (PRNP) genotypes that are different from those found predominantly in classical scrapie, there is some overlap so that there are genotypes in which both scrapie forms can occur. In this search for early atypical scrapie cases, we made use of an archive of fixed and frozen sheep samples, from both scrapie-affected and healthy animals (∼1850 individuals), dating back to the 1960s. Using a selection process based primarily on PRNP genotyping, but also on contemporaneous records of unusual clinical signs or pathology, candidate sheep samples were screened by Western blot, immunohistochemistry and strain-typing methods using tg338 mice. We identified, from early time points in the archive, three atypical scrapie cases, including one sheep which died in 1972 and two which showed evidence of mixed infection with classical scrapie. Cases with both forms of scrapie in the same animal as recognizable entities suggest that mixed infections have been around for a long time and may potentially contribute to the variety of scrapie strains.

    Objective: To make a clinical analysis on the basis of 36cases of atypical genital herpes (GH) patients. Methods: Thirty-six cases of atypical GH were diagnosedclinically, and their case histories, symptoms and signs wererecorded in detail and followed up. Polymerase chain reaction(PCR) was adopted for testing HSV2-DNA with cotton-tippedswabs. Enzyme-linked immuno sorbent assay (ELISA) forserum anti-HSV2-IgM was done to establish a definfiivediagnosis. Other diagnoses were excluded at the same time bytesting for related pathogens including fungi, Chlamydia,Mycoplasma, Treponema pallidum, gonococci, Trichomonas,etc. Results: The main clinical manifestations of atypical GHwere: (1) small genital ulcers; (2) inflammation of urethralmeatus; (3) nonspecific genital erythema; (4) papuloid noduleson the glands; (5) nonspecific vaginitis. Twenty-three cases(64%) tested by PCR were HSV2-DNA sera-positive, and 36cases (100 %) anti-HSV2-IgM sera-positive by ELISA. Conclusion: atypical HSV is difficult to be diagnosed. Butthe combination of PCR and ELIAS will be helpful to thediagnosis of atypical HSV.

    Full Text Available [english] Although both atypical fibroxanthoma and squamous cell carcinoma arise on top of sun-damaged skin of the elderly, there is no evidence in literature reporting a synchronous presentation of primary lesions of both malignancies in the head and neck regions. We report a case of synchronous atypical fibroxanthoma and squamous cell carcinoma in situ (Bowen’s disease of the head and neck in an otherwise normal old Caucasian male patient. We reviewed the literature for cases of head and neck atypical fibroxanthoma in association with other skin malignancies with an overview over the risk factors and modalities of treatment. We would like to raise the awareness for the concept of multiple synchronous primary malignant lesions and the importance to anticipate and differentiate between different pathologies in order to provide adequate investigations and treatment for the patient. [german] Obwohl sowohl das atypische Fibroxanthom der Haut als auch das Plattenepithelkarzinom bei sonnengeschädigter Haut älterer Menschen gehäuft vorkommen, gibt es in der Literatur keine Beschreibung eines simultanen Auftretens beider Malignome als Primärläsionen im Kopf-Hals-Bereich. Aus diesem Grund möchten wir über einen Fall berichten, bei dem sowohl ein atypisches Fibroxanthom als auch ein Morbus Bowen (als in situ Variante des Plattenepithelkarzinoms im Kopf-Hals-Bereich eines sonst gesunden 74-jährigen männlichen Patienten aufgetreten ist.

    Streptococcal infections of oral tissues are mainly seen in young children who experience a variety of upper respiratory tract infections. The disease is characterized by fever, lymphadenopathy, and ulcers on the gingiva, lips, and tonsils. This case report presents an atypical streptococcal infection of the gingiva in an 18-year-old man. The patient was referred to the periodontology department complaining of a 2-month history of gingival enlargement. He had persistent fever (39.5 degrees C) and general malaise for 2 weeks. Intraoral examination revealed extremely inflamed and enlarged gingiva with spontaneous bleeding and suppuration. Based on the otolaryngologic consultation and the hematologic, immunologic, and microbiologic tests, the final diagnosis was an atypical streptococcal gingivitis with chronic adenoid-related mouth breathing and oral hygiene neglect as contributing factors. Treatment consisted of a broad-spectrum antibiotic regimen, supragingival and subgingival debridement, adenoidectomy, and scaling and root planing. A good response to nonsurgical therapy was achieved despite poor patient compliance, and no recurrence of gingival enlargement was observed after 1 year. Streptococcal gingivitis should be included in the differential diagnosis of suppurative gingival enlargements. Furthermore, chronic mouth breathing may initiate and/or contribute to this disease.

    Circular and apparently trans-spliced RNAs have recently been reported as abundant types of transcripts in mammalian transcriptome data. Both types of non-colinear RNAs are also abundant in RNA-seq of different tissue from both the African and the Indonesian coelacanth. We observe more than 8,000 lincRNAs with normal gene structure and several thousands of circularized and trans-spliced products, showing that such atypical RNAs form a substantial contribution to the transcriptome. Surprisingly, the majority of the circularizing and trans-connecting splice junctions are unique to atypical forms, that is, are not used in normal isoforms.

    Atypical hemolytic uremic syndrome is characterized by the presence of thrombocytopenia, microangiopathic hemolytic anemia, and end-organ injury. In this report, we describe two patients with systemic lupus erythematosus who presented with findings compatible with atypical hemolytic uremic syndrome, complicated by acute kidney injury that was refractory to conventional therapies. Both patients exhibited a response to eculizumab, a monoclonal antibody to complement protein C5, with stabilization of their platelet count. On 1-year follow-up from their initial presentation, their hematologic disease remained in remission without recurrence. PMID:27556240

    Uremic encephalopathy is a well-known disease with typical MR findings including bilateral vasogenic or cytotoxic edema at the cerebral cortex or basal ganglia. Involvement of the basal ganglia has been very rarely reported, typically occurring in uremic-diabetic patients. We recently treated a patient who had non-diabetic uremic encephalopathy with an atypical lesion distribution involving the supratentorial white matter, without cortical or basal ganglia involvement. To the best of our knowledge, this is only the second reported case of non-diabetic uremic encephalopathy with atypical MR findings.

    A description is given of exhaust gas desulfurization by the Kawasaki-Kureha sodium sulfite-gypsum method, put into operation at the Shin Sendai Thermal Power Plant, Japan, by Tohoku Denryoku KK in March 1974. This process, also known as the double alkali method, is composed of three procedures: (1) absorption of sulfur dioxide gas in sodium sulfite solution to form sodium bisulfite and passage of the remainder of the exhaust into the atmosphere; (2) regeneration of liquid absorbent (secondary decomposition of sodium bisulfite by calcium carbonate into sodium sulfite, calcium sulfite, water and carbon dioxide) and of sodium sulfate, formed by oxidation of sodium sulfite in other processes, back to sodium bisulfite, by reaction with calcium sulfite and sulfuric acid; and (3) oxidation of calcium sulfite to calcium sulfate (gypsum). Calcium sulfate obtained as a reaction product in procedure (2) is combined with gypsum formed in procedure (3). During 6 months of operation, desulfurization was effected on an exhaust gas load of 420,000 N cu m/hr, where sulfur dioxide gas content varied from 400--800 ppm. At the absorption tower outflow before the afterburner, SO/sub 2/ concentrations ranged from 2--10 ppM, and never more than 15 ppM during short-term peaks. As by-product, 88 tons/day of gypsum (CaSO/sub 4/2H/sub 2/O) were obtained. Operational problems have been encountered in all parts of the process. These include: sodium sulfate formation; scaling-up problems from test plant operations; difficulties in automatic ignition of the after-burner, meandering of the filter cloth belt in the secondary decomposition equipment; plugging of oxidation tower; problems in centrifugal separation of water and gypsum.

    Industry and fossil fuel combustion are the main sources for urban carbon emissions. Most studies focus on energy consumption emission reduction and energy efficiency improvement. Material saving is also important for carbon emission reduction from a lifecycle perspective. IS (Industrial symbiosis) and UrS (urban symbiosis) have been effective since both of them encourage byproduct exchange. However, quantitative carbon emission reduction evaluation on applying them is still lacking. Consequently, the purpose of this paper is to fill such a gap through a case study in Kawasaki Eco-town, Japan. A hybrid LCA model was employed to evaluate to the lifecycle carbon footprint. The results show that lifecycle carbon footprints with and without IS and UrS were 26.66 Mt CO2e and 30.92 Mt CO2e, respectively. The carbon emission efficiency was improved by 13.77% with the implementation of IS and UrS. The carbon emission reduction was mainly from “iron and steel” industry, cement industry and “paper making” industry, with figures of 2.76 Mt CO2e, 1.16 Mt CO2e and 0.34 Mt CO2e, respectively. Reuse of scrape steel, blast furnace slag and waste paper are all effective measures for promoting carbon emission reductions. Finally, policy implications on how to further promote IS and UrS are presented. - Highlights: • We evaluate carbon emission reduction of industrial and urban symbiosis (IS/UrS). • Hybrid LCA model was used to evaluate lifecycle carbon footprint. • Carbon emission efficiency was improved by 13.77% after applying IS/UrS. • The importance of UrS in responding carbon reduction was addressed in the paper

    Full Text Available Gary Ventolini, Ravi Patel, Robert Vasquez Texas Tech University Health Sciences Center Permian Basin, Odessa, TX, USA Objective: Lichen sclerosus (LS is a chronic progressive inflammatory autoimmune-induced disease that primarily affects the epidermis and dermis of the external genital-anal region. Intense and recalcitrant pruritus is the hallmark of LS. Physical exam reveals thinning, hyperkeratosis, and parchment-like appearance. However, the classic symptom and signs of LS may not always be present and patients may be asymptomatic for pruritus. Hence, we describe 15 misdiagnosed cases with atypical clinical presentations. We believe that the absence of pruritus contributed to their initial misdiagnosis. The purpose of this paper is to increase awareness of atypical presentations of LS. Methods: Data base review of de-identified clinical case pictures was performed. All patients had histopathology-confirmed diagnoses of LS. The data base file contains 800 cases of vulvovaginal disorders. The Institutional Review Board (IRB considered that searching a de-identified data base of pictures did not require IRB approval. Results: We identified 15 different atypical clinical cases. Patient ages were 18–75 years old. These patients were asymptomatic for pruritus and were misdiagnosed before they presented to the vulvovaginal specialized clinic. Conclusion: Fifteen patients asymptomatic for pruritus with histopathology-confirmed diagnosis of LS were identified. They illustrate atypical clinical presentations that LS may have.

    There is scant research on the clinical utility of differentiating International Classification of Diseases (ICD) 10 diagnoses F50.0 anorexia nervosa (typical AN) and F50.1 atypical anorexia. We reviewed systematically records of 47 adolescents who fulfilled criteria for ICD-10 F50.0 (n = 34) or F50.1 (n = 13), assessing the impact of diagnostic subtype, comorbidity, background factors and treatment choices on recovery. Atypical AN patients were significantly older (p = 0.03), heavier (minimum body mass index 16.7 vs 15.1 kg/m(2) , p = 0.003) and less prone to comorbidities (38% vs 71%, p = 0.04) and had shorter, less intensive and less costly treatments than typical AN patients. The diagnosis of typical versus atypical AN was the sole significant predictor of treatment success: recovery from atypical AN was 4.3 times (95% confidence interval [1.1, 17.5]) as likely as recovery from typical AN. Overall, our findings indicate that a broader definition of AN may dilute the prognostic value of the diagnosis, and therefore, ICD-11 should retain its distinction between typical and atypical AN.

  17. The $\\mathbf \\Gamma$-limit of the two-dimensional Ohta-Kawasaki energy. I. Droplet density

    Goldman, Dorian; Serfaty, Sylvia

    2012-01-01

    This is the first in a series of two papers in which we derive a $\\Gamma$-expansion for a two-dimensional non-local Ginzburg-Landau energy with Coulomb repulsion, also known as the Ohta-Kawasaki model in connection with diblock copolymer systems. In that model, two phases appear, which interact via a nonlocal Coulomb type energy. We focus on the regime where one of the phases has very small volume fraction, thus creating small "droplets" of the minority phase in a "sea" of the majority phase. In this paper we show that an appropriate setting for $\\Gamma$-convergence in the considered parameter regime is via weak convergence of the suitably normalized charge density in the sense of measures. We prove that, after a suitable rescaling, the Ohta-Kawasaki energy functional $\\Gamma$-converges to a quadratic energy functional of the limit charge density generated by the screened Coulomb kernel. A consequence of our results is that minimizers (or almost minimizers) of the energy have droplets which are almost all asy...

    Atypical hemolytic uremic syndrome (aHUS) is characterized by complement attack against host cells due to mutations in complement proteins or autoantibodies against complement factor H (CFH). It is unknown why nearly all patients with autoimmune aHUS lack CFHR1 (CFH-related protein-1). These patients have autoantibodies against CFH domains 19 and 20 (CFH19-20), which are nearly identical to CFHR1 domains 4 and 5 (CFHR14-5). Here, binding site mapping of autoantibodies from 17 patients using mutant CFH19-20 constructs revealed an autoantibody epitope cluster within a loop on domain 20, next to the two buried residues that are different in CFH19-20 and CFHR14-5. The crystal structure of CFHR14-5 revealed a difference in conformation of the autoantigenic loop in the C-terminal domains of CFH and CFHR1, explaining the variation in binding of autoantibodies from some aHUS patients to CFH19-20 and CFHR14-5. The autoantigenic loop on CFH seems to be generally flexible, as its conformation in previously published structures of CFH19-20 bound to the microbial protein OspE and a sialic acid glycan is somewhat altered. Cumulatively, our data suggest that association of CFHR1 deficiency with autoimmune aHUS could be due to the structural difference between CFHR1 and the autoantigenic CFH epitope, suggesting a novel explanation for CFHR1 deficiency in the pathogenesis of autoimmune aHUS.

    Atypical pressure ulcers (APU) are distinguished from common pressure ulcers (PU) with both unusual location and different aetiology. The occurrence and attempts to characterise APU remain unrecognised. The purpose of this cohort study was to analyse the occurrence of atypical location and the circumstances of the causation, and draw attention to the prevention and treatment by a multidisciplinary team. The cohort study spanned three and a half years totalling 174 patients. The unit incorporates two weekly combined staff meetings. One concentrates on wound assessment with treatment decisions made by the physician and nurse, and the other, a multidisciplinary team reviewing all patients and coordinating treatment. The main finding of this study identified APU occurrence rate of 21% within acquired PU over a three and a half year period. Severe spasticity constituted the largest group in this study and the most difficult to cure wounds, located in medial aspects of knees, elbows and palms. Medical devices caused the second largest occurrence of atypical wounds, located in the nape of the neck, penis and nostrils. Bony deformities were the third recognisable atypical wound group located in shoulder blades and upper spine. These three categories are definable and time observable. APU are important to be recognisable, and can be healed as well as being prevented. The prominent role of the multidisciplinary team is primary in identification, prevention and treatment.

    Rhinosinusitis affects approximately 20% of the population, and the chronic rhinosinusitis represents over 90% of all cases of rhinosinusitis. The correct diagnosis is important for proper treatment and to predict its evolution. This study presents two cases of atypical frontal sinus disease, which the follow-up revealed a diagnosis of fungal rhinosinusitis. The present study aims to describe the cases of two patients with atypical lesions on the left frontal sinus; the treatment options, surgical approach, results, diagnosis and follow-up are further discussed. A significant increase in the reported cases of fungal rhinosinusitis has been seen in the last two decades, justified by the use of broad-spectrum antibiotics and steroids, as well as the increased number of immunocompromised individuals. This study reports the cases of two patients with a type of fungal rhinosinusitis named "fungal ball", characterized by a tangle of hyphae in the sinuses without tissue invasion. The treatment included surgical removal of the fungal infectious process with aeration of the affected sinus, and the procedure was successfully performed in our patients.

    Breast metastases from extramammary malignancies are uncommon. The most common sources are lymphomas/leukemias and melanomas. Some of the less common sources include carcinomas of the lung, ovary, and stomach, and infrequently, carcinoid tumors, hypernephromas, carcinomas of the liver, tonsil, pleura, pancreas, cervix, perineum, endometrium and bladder. Breast metastases from extramammary malignancies have both hematogenous and lymphatic routes. According to their routes, there are common radiological features of metastatic diseases of the breast, but the features are not specific for metastases. Typical ultrasound (US) features of hematogenous metastases include single or multiple, round to oval shaped, well-circumscribed hypoechoic masses without spiculations, calcifications, or architectural distortion; these masses are commonly located superficially in subcutaneous tissue or immediately adjacent to the breast parenchyma that is relatively rich in blood supply. Typical US features of lymphatic breast metastases include diffusely and heterogeneously increased echogenicities in subcutaneous fat and glandular tissue and a thick trabecular pattern with secondary skin thickening, lymphedema, and lymph node enlargement. However, lesions show variable US features in some cases, and differentiation of these lesions from primary breast cancer or from benign lesions is difficult. In this review, we demonstrate various US appearances of breast metastases from extramammary malignancies as typical and atypical features, based on the results of US and other imaging studies performed at our institution. Awareness of the typical and atypical imaging features of these lesions may be helpful to diagnose metastatic lesions of the breast.

  13. Current status of atypical antipsychotics for the treatment of fibromyalgia.

    Rico-Villademoros, F; Calandre, E P; Slim, M

    2014-06-01

    The treatment of fibromyalgia requires pharmacological and nonpharmacological therapies. The pharmacological treatment of fibromyalgia is limited to a few drugs that have been demonstrated to be moderately effective in some but not all dimensions of the disease. Therefore, the search for new drugs to treat this condition is warranted. Atypical antipsychotics offered an attractive alternative because they had been shown to be active against several key symptoms of fibromyalgia. The results of open-label studies, however, appear to indicate that atypical antipsychotics are poorly tolerated in patients with fibromyalgia, and only quetiapine XR has been studied in randomized controlled trials. Quetiapine XR has demonstrated effectiveness in treating comorbid major depression, anxiety and sleep disturbance. However, in two randomized controlled trials, quetiapine XR was not differentiated from placebo and failed to demonstrate noninferiority to amitriptyline in terms of improving overall symptomatology. The effect of quetiapine XR on pain and its usefulness as part of a combination pharmacological regimen should be further evaluated. Overall, the use of quetiapine (initiated at a low dose and slowly titrated) in fibromyalgia should be limited to patients with comorbid major depression or patients who are currently receiving other treatments and have unresolved and disabling depressive and/or anxiety symptoms.

    Background and Objectives: Dengue fever (DF) is transmitted by Aedes aegypti mosquitoes. With growing population, rapid urbanization and lack of appropriate sanitary measures, proliferation of mosquitoes and subsequent dengue infections have increased rampantly with an estimated 30-fold increase in incidence over last five decades. With rising disease burden, atypical manifestations have increased as well, which are missed most often due to lack of awareness. Our aim was to look for the atypical manifestations of dengue fever. Materials and Methods: A prospective hospital based observational study was conducted at hospitals of Kasturba Medical College in Mangalore over a period of two years (June–2010 to May–2012). One-hundred fifty ELISA confirmed IgM-dengue sero-positive cases satisfying WHO criteria were examined clinically and laboratory data assessed till they got discharged from hospital after ruling out other causes of fever. Atypical manifestations in dengue fever were noted and analyzed. Results: Most common symptoms noticed were myalgia, headache, rash, arthralgia, pain in abdomen and nausea. More than half of the study group had one or the other atypical manifestation. Liver function test derangement was most often seen. Most common atypical manifestation was hepatitis found in 40.6% patients. Febrile diarrhea, renal failure, Acalculous cholecystitis and conduction abnormalities of heart were among other common manifestations. Three patients died of multi-organ dysfunction, disseminated intravascular coagulation and shock. Platelet count did not correlate well with severity of bleeding. Overall recovery rate was good. Conclusion: Some of the atypical manifestations of dengue fever are no more a rare entity. Clinical vigilance for these manifestations is important for timely detection and management as some of them could be fatal. PMID:24596727

    Crithidia luciliae, displaying an annular image due to a kinetoplast containing double stranded DNA. Other structures such as membrane, flagellum and basal corpuscle can be stained as well, showing what is called atypical fluorescent images. As C. luciliae belongs to the Trypanosomatidae family, which include the human pathogens Trypanosoma cruzi and Leishmania spp., it was considered that these atypical images could be caused by cross-reactions. Serological studies for Chagas’ disease were performed in 105 serum samples displaying atypical images. Sixty four percent of the samples from non endemic and 78.3% from endemic areas for Chagas’ disease showed fluorescence in both, membrane and flagellum (joint image. Fifty samples from normal blood donors and 57 samples from patients with conective tissue diseases were tested with C. luciliae. None of them presented the joint image except for two patients with lupus who were also chagasic. In addition, 54 samples from chagasic patients were studied and all of them presented the joint image. We also studied 46 samples from patients with leishmaniasis from whom 28 were co-infected with T. cruzi. The joint image was observed in 88.0% of the samples with leishmaniasis and in 89.3% of the co-infected samples. The results suggest that C. luciliae could be used as an economical, and of low risk, alternative substrate for the serological diagnosis of Chagas’ disease, even though it does not discriminate for Leishmania spp. infection. This study also suggests that whenever atypical images are observed in C. luciliae during the search for anti-DNA antibodies, it would be convenient to submit the patient to clinical and serological tests for the diagnosis of leishmaniosis and Chagas’ disease.

    We present a case of an atypical recurrent meningioma of the sacrum with pulmonary metastasis in a 31-year-old man. He presented with deep-seated buttock pain and urinary hesitancy for 3 months. MRI revealed a lesion occupying the central and left side of the sacral canal at the S1-S2 level. Surgical excision of the lesion via a posterior approach was undertaken, and the patient became symptom-free post-operatively. Histology confirmed atypical meningioma. Eight months later he re-presented with similar symptoms, and MRI confirmed local recurrence. The patient underwent left hemisacrectomy. Six months later he again presented with low back pain and MRI confirmed a second local recurrence. A CT scan of the chest showed multiple lung metastases. The patient died of a severe chest infection 18 months later. (orig.)

    We report two rare cases of iliopsoas bursitis extending into the retroperitoneal space. The first lesion contained much gas, mimicking a retroperitoneal abscess, and the second was responsible for atypical inguinal pain. The diagnosis was made by contrast-enhanced CT in both cases and arthrography in the first case. Iliopsoas bursitis in these two patients, it is hypothesized, extended into the retroperitoneum, at least in part, by way of intraneural or perineural structures. (orig.)

    Abstract Introduction: Aggressive digital papillary adenocarcinoma (ADPA) is a rare sweat gland tumor that is found on the fingers, toes, and the digits. To date, <100 cases have been reported in the literature. Apart from 1 case reported in the thigh, all of them were on digital or nondigital acral skin. Case presentation: A 67-year-old Caucasian woman was admitted to the hospital due to a mass on the scalp. This lesion was present for almost a year. It was a semimobile cyctic mass that elevated the scalp. There was no change in the skin color. Its dimensions were 1.5 × 1 × 0.6 cm. The laboratory, clinic, and radiologic findings (head x-ray) of the patient were normal. It was evaluated as a benign lesion such as lipoma or epidermal cyst by a surgeon due to a small semimobile mass and no erosion of the skull. It was excised by a local surgery excision. The result of the pathologic examination was aggressive papillary adenocarcinoma. This diagnosis is synonymous with ADPA. Conclusion: In our case, localization was scalp. This localization is the first for this tumor in the literature. In addition, another atypical localization of this tumor (ADPA) is thigh in the literature. This case was presented due to both the rare and atypical localizations. That is why, in our opinion, revision of “digital” term in ADPA is necessary due to seem in atypical localizations like thigh and scalp. PMID:27428196

    The atypical measles syndrome is a relatively new disease that was first recognized 15 years ago. Initially, it occurred in children who were exposed to wild measles virus several years after they were immunized with killed measles vaccine. It was characterized by a two- to three-day prodrome of high fever, cough, headache, and myalgia followed by a rash that resembled Rocky Mountain spotted fever, scarlet fever, or varicella and associated with roentgenographic evidence of pneumonia with or without pleural effusion. This report highlights three unusual manifestations of this syndrome: 1) transient hepatitis, 2) persistence of pulmonary lesions for several years, and 3) occurrence of excessively high measles hemagglutination-inhibition antibody titers. Today, this syndrome occurs predominantly in adolescents and young adults.

    A large epidemic of Chikungunya fever currently affects the Caribbean, Central and South America. Despite a high number of reported cases, little is known on the occurrence of severe clinical complications. We describe four Venezuelan patients with a severe and/or lethal course who exhibit unusual manifestations of the disease. Case 1 describes a 75 year-old man with rapid onset of septic shock and multi-organ failure. Cases 2 and 3 describe two patients with rapid aggressive clinical course who developed shock, severe purpuric lesions and a distinct area large of necrosis in the nasal region. Case 4 depicts a splenectomized woman with shock, generalized purpuric lesions, bullous dermatosis and acronecrosis of an upper limb. Chikungunya fever in the Western hemisphere may also associate with atypical and severe manifestations. Some patients experience a life-threatening, aggressive clinical course, with rapid deterioration and death due to multisystem failure. PMID:26793440

    HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets) is a severe variant of pre-eclampsia whose pathogenesis remains unclear. Recent evidence and clinical similarities suggest a link to atypical hemolytic uremic syndrome, a disease of excessive activation of the alternative complement pathway effectively treated with a complement inhibitor, eculizumab. Therefore, we used a functional complement assay, the modified Ham test, to analyze sera of women with classic or atypical HELLP syndrome, pre-eclampsia with severe features, normal pregnancies, and healthy nonpregnant women. Sera were also evaluated using levels of the terminal product of complement activation (C5b-9). We tested the in vitro ability of eculizumab to inhibit complement activation in HELLP serum. Increased complement activation was observed in participants with classic or atypical HELLP compared with those with normal pregnancies and nonpregnant controls. Mixing HELLP serum with eculizumab-containing serum resulted in a significant decrease in cell killing compared with HELLP serum alone. We found that HELLP syndrome is associated with increased complement activation as assessed with the modified Ham test. This assay may aid in the diagnosis of HELLP syndrome and could confirm that its pathophysiology is related to that of atypical hemolytic uremic syndrome.

    Full Text Available Scrapie is a transmissible spongiform encephalopathy (TSE in sheep and goats. In recent years, atypical scrapie cases were identified that differed from classical scrapie in the molecular characteristics of the disease-associated pathological prion protein (PrP(sc. In this study, we analyze the molecular and neuropathological phenotype of nine Swiss TSE cases in sheep and goats. One sheep was identified as classical scrapie, whereas six sheep, as well as two goats, were classified as atypical scrapie. The latter revealed a uniform electrophoretic mobility pattern of the proteinase K-resistant core fragment of PrP(sc distinct from classical scrapie regardless of the genotype, the species, and the neuroanatomical structure. Remarkably different types of neuroanatomical PrP(sc distribution were observed in atypical scrapie cases by both western immunoblotting and immunohistochemistry. Our findings indicate that the biodiversity in atypical scrapie is larger than expected and thus impacts on current sampling and testing strategies in small ruminant TSE surveillance.

    Aim: Atypical lymphocytes usually described as lymphocytes with altered shape, increased DNA amount, and larger size. For analysis of cause of genesis and source of atypical lymphocytes during African swine fever virus (ASFV) infection, bone marrow, peripheral blood, and in vitro model were investigated. Materials and Methods: Atypical lymphocytes under the influence of ASFV were studied for morphologic, cytophotometric, and membrane surface marker characteristics and were used in vivo and in vitro models. Results: This study indicated the increased size, high metabolic activity, and the presence of additional DNA amount in atypical lymphocytes caused by ASFV infection. Furthermore, in atypical lymphocytes, nuclear-cytoplasmic ratio usually decreased, compared to normal lymphocytes. In morphology, they looking like lymphocytes transformed into blasts by exposure to mitogens or antigens in vitro. They vary in morphologic detail, but most of them are CD2 positive. Conclusions: Our data suggest that atypical lymphocytes may represent an unusual and specific cellular response to ASFV infection. PMID:27536044

    Full Text Available The Herpes Zoster is produced by the reactivation of the Chicken Pox Zoster Virus. It has an incidence of three cases for each thousand inhabitants a year, and they increase the possibility to suffer it with the age. A 48 year old case of a patient with atypical Zoster with postherpetic neuralgia who came to the Dermatology consultation with cutaneous and mucous lesions is presented. This article has the objective to describe the evolution of the Herpes Zoster in the last patient diagnosed like seropositive to the virus of Human Immunodeficiency Virus It is considered of concern once both entities association was given, indicator that although Herpes Zoster incidence is low, considering the possible presence of diseases that involve the immune system. We conclude that in the presence of the clinical variety of Atypical Herpes Zoster, the coexistence of other diseases that compromise the immune system, as the Human Immunodeficiency Virus must be considered.

    Full Text Available Abstract Background Diurnal rhythm-mediated endogenous cortisol levels in humans are characterised by a peak in secretion after awakening that declines throughout the day to an evening trough. However, a significant proportion of the population exhibits an atypical cycle of diurnal cortisol due to shift work, jet-lag, aging, and mental illness. Results The present study has demonstrated a correlation between elevation of cortisol in the evening and deterioration of visual object recognition memory. However, high evening cortisol levels have no effect on spatial memory. Conclusion This study suggests that atypical evening salivary cortisol levels have an important role in the early deterioration of recognition memory. The loss of recognition memory, which is vital for everyday life, is a major symptom of the amnesic syndrome and early stages of Alzheimer's disease. Therefore, this study will promote a potential physiologic marker of early deterioration of recognition memory and a possible diagnostic strategy for Alzheimer's disease.

    The Chelonid fibropapilloma-associated herpesvirus (CFPHV; ChHV5) is believed to be the causative agent of fibropapillomatosis (FP), a neoplastic disease of marine turtles. While clinical signs and pathology of FP are well known, research on ChHV5 has been impeded because no cell culture system for its propagation exists. We have cloned a BAC containing ChHV5 in pTARBAC2.1 and determined its nucleotide sequence. Accordingly, ChHV5 has a type D genome and its predominant gene order is typical for the varicellovirus genus within the alphaherpesvirinae. However, at least four genes that are atypical for an alphaherpesvirus genome were also detected, i.e. two members of the C-type lectin-like domain superfamily (F-lec1, F-lec2), an orthologue to the mouse cytomegalovirus M04 (F-M04) and a viral sialyltransferase (F-sial). Four lines of evidence suggest that these atypical genes are truly part of the ChHV5 genome: (1) the pTARBAC insertion interrupted the UL52 ORF, leaving parts of the gene to either side of the insertion and suggesting that an intact molecule had been cloned. (2) Using FP-associated UL52 (F-UL52) as an anchor and the BAC-derived sequences as a means to generate primers, overlapping PCR was performed with tumor-derived DNA as template, which confirmed the presence of the same stretch of "atypical" DNA in independent FP cases. (3) Pyrosequencing of DNA from independent tumors did not reveal previously undetected viral sequences, suggesting that no apparent loss of viral sequence had happened due to the cloning strategy. (4) The simultaneous presence of previously known ChHV5 sequences and F-sial as well as F-M04 sequences was also confirmed in geographically distinct Australian cases of FP. Finally, transcripts of F-sial and F-M04 but not transcripts of lytic viral genes were detected in tumors from Hawaiian FP-cases. Therefore, we suggest that F-sial and F-M04 may play a role in FP pathogenesis.

  12. Hematological Side Effects of Atypical Antipsychotic Drugs

    2009-10-01

    Full Text Available Atypical antipsychotics cause less frequently extrapyramidal system symptoms, neuroleptic malignant syndrome and hyperprolactinemia than typical antipsychotics. However hematological side effects such as leukopenia and neutropenia could occur during treatment with atypical antipsychotics. These side effects could lead to life threatening situations and the mortality rate due to drug related agranulocytosis is about 5-10%. There are several hypothesis describing the mechanisms underlying drug induced leukopenia and/or neutropenia such as direct toxic effects of these drugs upon the bone marrow or myeloid precursors, immunologic destruction of the granulocytes or supression of the granulopoiesis. Clozapine is the antipsychotic agent which has been most commonly associated with agranulocytosis. A nitrenium ion which is formed by the bioactivation of clozapine is thought to have an important role in the pathophysiogy of this adverse effect. Aside from clozapine, there are several case reports reporting an association between olanzapine, quetiapine, risperidone, ziprasidone, aripiprazole and leukopenia. We did not find any study or case report presenting amisulpride or sulpride related hematological side effects in our literature search. Patients who had hematological side effects during their previous antipsychotic drug treatments and who had lower baseline blood leukocyte counts, have higher risk to develop leukopenia or neutropenia during their current antipsychotic treatment. Once leukopenia and neutropenia develops, drugs thought to be responsible for this side effect should be discontinued or dosages should be lowered. In some cases iniatition of lithium or G-CSF (granulocyte colony-stimulating factor therapy may be helpful in normalizing blood cell counts. Clinicans should avoid any combination of drugs known to cause hematological side effects. Besides during antipsychotic treatment, infection symptoms such as fever, cough, sore throat or

    Objective To report the first case of central nervous system Whipple's disease (WD) with relatively good prognosis in China and present a brief review of central nervous system WD so as to improve the understanding of the diagnosis and treatment of this rare disease. Methods The clinical data of diagnosis, treatment and prognosis of one case of 35-year-old female was analysed in detail. Results Headache, hemiplesia and dementia were the main symptoms of this case and hypercranial pressure crisis occurred. During the course of disease, the patient successively presented paroxysmal extremity convulsion, right leg weakness, urinary incontinence, overeating, body mass increase. Despite of high dose of corticosteroid, penicillin and compound sulfamethoxazole were used, no effect was seen. Along with the increasing of intracranial pressure, cerebral hernia occurred. Cerebrospinal fluid examination indicated that glucose and chloride were normal while protein was obviously increased to 1700 mg/L. Electrocardiography (EEG) showed slow wave in right frontal and temporal lobes. Serial magnetic resonance imaging (MRI) revealed mutiple long Ti and long T2 signals mainly in right cerebral hemisphere, frontal parietal temporal lobes, seraioval center and basal ganglion, with edema and irregular loose contrast and extended to left cerebral. Brain biopsy showed large pieces of necrosis at right fronto-temporal lobe with massive infiltration of lymphocytes and plasmocytes at perivascular and brain tissue, and exudation of glitter cells. Positive PAS and methenamine silver staining revealed bacterial particles inglitter cells. Central nervous systemtumor, demyelinating disease and inflammatory pseudotumor were excluded. Both clinical symptoms and neuroimging recovered well after regular antibiotic therapy.Conclusion Central nervous system WD is a rare disease with complicated symptoms and imaging characters challenging diagnosis and treatment.

The phenomenology of OCD in children and adolescent is strikingly similar to that of adults. But at times, the presentation of OCD may be so atypical or unusual in children and adolescents that may lead to misdiagnosis or delay in diagnosis. We report a case of 10-year-old child who was initially misdiagnosed with schizophrenia, and treated with antipsychotic for 2 months. But once the core symptoms were recognized as obsessions and compulsions and appropriately treated in the line of OCD, the symptoms resolved significantly.

    Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.

Different terminologies have been described in HUS, which are as follows: (1 D+ HUS: Presentation with a preceding diarrhea; (2 typical HUS: D+ HUS with a single and self-limited episode; (3 atypical HUS (aHUS: Indicated those with complement dysregulation; (4 recurrent HUS: Recurrent episodes of thrombocytopenia and/or microangiopathic hemolytic anemia (MAHA after improvement of hematologic abnormalities; and (5 familial HUS: Necessary to distinct synchronous outbreaks of D+ HUS in family members and asynchronous disease with an inherited risk factor. aHUS is one of the potential causes of end-stage renal disease (ESRD in children. It has a high recurrence after renal transplantation in some genetic forms. Therefore, recognition of the responsible mechanism and proper prophylactic treatment are recommended to prevent or delay the occurrence of ESRD and prolong the length of survival of the transplanted kidney. A computerized search of MEDLINE and other databases was carried out to find the latest results in pathogenesis, treatment, and prevention of aHUS.

    Neurobiological abnormalities underlying atypical depression have previously been suggested. The purpose of this study was to explore differences at functional brain imaging between depressed patients with and without atypical features and healthy controls. Twenty-three out-patients with chronic depressive disorder recruited from a service for patients with audiological symptoms were investigated. Eleven fulfilled the DSM-IV criteria for atypical depression (mood reactivity and at least two of the following: weight gain, hypersomnia, leaden paralysis and interpersonal rejection sensitivity). Twenty-three healthy subjects served as controls. Voxel-based analysis was applied to explore differences in {sup 99m}Tc-HMPAO uptake between groups. Patients in the atypical group had a higher prevalence of bilateral hearing impairment and higher depression and somatic distress ratings at the time of SPECT. Significantly higher tracer uptake was found bilaterally in the atypical group as compared with the non-atypicals in the sensorimotor (Brodmann areas, BA1-3) and premotor cortex in the superior frontal gyri (BA6), in the middle frontal cortex (BA8), in the parietal associative cortex (BA5, BA7) and in the inferior parietal lobule (BA40). Significantly lower tracer distribution was found in the right hemisphere in the non-atypicals compared with the controls in BA6, BA8, BA44, BA45 and BA46 in the frontal cortex, in the orbito-frontal cortex (BA11, BA47), in the postcentral parietal cortex (BA2) and in the multimodal association parietal cortex (BA40). The differences found between atypical and non-atypical depressed patients suggest different neurobiological substrates in these patient groups. The putative links with the clinical features of atypical depression are discussed. These findings encourage the use of functional neuroimaging in psychiatric disorders. (orig.)

    Hitherto it has not been usual to talk in the German language about the therapy-oriented concept of two forms of the progress of atypical depression (Type A and Type V). The characteristic symptom of Type A is angst, together with phobias, physical complaints, etc. In Type V there are vegetative symptoms, often towards evening (Hypersomnia, difficulty in getting to sleep, increased appetite, increased weight, increased libido), accompanied by hysterical extrovert personality traits, and of intermittent occurrence. These clinical pictures are amenable to psychopharmalogical therapy. In conformity with the assumption of "somatic accommodation" treatment with antidepressives is recommended in the case neurotic depression, too, at least in the initial stages of treatment.

    In a consecutive series of 1,925 head injuries, 283 patients (14.7%), could not be classified, neither in the group of simple head injuries without cerebral symptoms, nor in the group of typical concussions characterized by immediate amnesia or observed coma. We have prefered the rather neutral term of atypical early posttraumatic syndromes. In this group, apart from neurovegetative manifestations, partial disturbances of consciousness and perception, we have also classified delayed disturbances of consciousness. Special attention has been given to migraineous phenomena and to a syndrome, characteristic for children, described by Mealey. This is an intermediate group important from a medico-legal point of view because certain transient cerebral manifestations risk to be mistaken for psychological reactions. On the other hand symptoms probably of psychic origin were discussed. PMID:4469864

    Metastatic pulmonary calcification is a condition of calcium deposition in the normal pulmonary parenchyma, and this is secondary to abnormal calcium metabolism without any prior soft tissue damage. The predisposing factors for this condition include chronic renal failure, hypercalcemia and increased tissue alkalinity. The most common radiologic manifestation consists of poorly defined nodular opacities in the upper lung zone. These opacities reflect the deposition of calcium salts in the pulmonary interstitium. We present here a case of metastatic pulmonary calcification in a patient who recovered from pneumonia with sepsis and whose high-resolution CT (HRCT) images demonstrated localized parenchymal airspace calcification that was limited to the bilateral lower lobes. These lower lobes had been involved with pneumonic consolidation without calcification, as seen on the previous CT scan. In summary, we report here on an atypical presentation of metastatic pulmonary calcification that showed dense airspace consolidation localized to the bilateral lower lobes in a patient with primary hyperparathyroidism and pneumonia.

    This study compares the effects of atypical and conventional antipsychotic medications on treatment continuation and outcomes in a first admission sample of patients with schizophrenia treated in usual practice settings. In a sample of 189 participants with a research diagnosis of DSM-IV schizophrenia drawn from the Suffolk County Mental Health Project, we compared the effects of atypical and conventional agents on change of medication, medication gaps, and rehospitalization. For these analyses we used the method of survival analysis for recurrent events, in which the episodes of treatment rather than individual subjects are the units of analysis. In addition, we compared improvement in positive and negative symptoms from intake to 24- or 48-month followups for subjects who stayed on one type of medication or changed to atypicals from conventional antipsychotics. Atypical agents were associated with lower risk of medication change, medication gaps, and rehospitalization. Both conventional and atypical agents were associated with improvement of positive symptoms at followup, but only subjects on atypical agents at followup experienced a significant improvement in negative symptoms. We conclude that in usual practice settings, as in randomized clinical trials, atypical agents are associated with improved treatment continuation and outcomes.

    Full Text Available Abstract Aims The aim of this study was to find out the characteristic morphology of malignant atypical cells which were missed on routine cytology of urine. Materials and methods In this retrospective study, we examined detailed cytomorphology of 18 cases of atypical urinary cytology which were missed on routine examination and were further proved on histopathology as transitional cell carcinoma (TCC of bladder. The cytological features of these cases were compared with 10 cases of benign urine samples. Results There were 11 cases of high grade TCC and 7 cases of low grade TCC on histopathology of the atypical urine samples. Necrosis in the background and necrosed papillae were mostly seen in malignant atypical cells. The comet cells and cells with India ink nuclei (single cells with deep black structure-less nuclei were only observed in malignant atypical cells. The most consistent features in malignant atypical cells were: i high nuclear and cytoplasmic (N/C ratio ii nuclear pleomorphism iii nuclear margin irregularity iv hyperchromasia and v chromatin abnormalities Conclusion The present study emphasizes that nuclear features such as high N/C ratio, hyperchromasia and chromatin abnormalities are particularly useful for assessing the malignant atypical cells. Other cytological features such as comet cells and cells with India ink nuclei are also helpful for diagnosis but have limited value because they are less frequently seen.

    The chemokine system is a fundamental component of cancer-related inflammation involved in all stages of cancer development. It controls not only leukocyte infiltration in primary tumors but also angiogenesis, cancer cell proliferation, and migration to metastatic sites. Atypical chemokine receptors are a new, emerging class of regulators of the chemokine system. They control chemokine bioavailability by scavenging, transporting, or storing chemokines. They can also regulate the activity of canonical chemokine receptors with which they share the ligands by forming heterodimers or by modulating their expression levels or signaling activity. Here, we summarize recent results about the role of these receptors (atypical chemokine receptor 1/Duffy antigen receptor for chemokine, atypical chemokine receptor 2/D6, atypical chemokine receptor 3/CXC-chemokine receptor 7, and atypical chemokine receptor 4/CC-chemokine receptor-like 1) on the tumorigenesis process, indicating that their effects are strictly dependent on the cell type on which they are expressed and on their coexpression with other chemokine receptors. Indeed, atypical chemokine receptors inhibit tumor growth and progression through their activity as negative regulators of chemokine bioavailability, whereas, on the contrary, they can promote tumorigenesis when they regulate the signaling of other chemokine receptors, such as CXC-chemokine receptor 4. Thus, atypical chemokine receptors are key components of the regulatory network of inflammation and immunity in cancer and may have a major effect on anti-inflammatory and immunotherapeutic strategies.

    Moya-moya is a rare cerebrovascular disease characterized by the progressive occlusion of cerebral vessels with partial switching off the circle of Willis and arteries that feed it. The article provides a review of literature, modern diagnostic criteria and a description of a single clinical case. The onset of the disease in this patient was characterized by headache and speech disorders.An analysis of speech disorders showed that they were systemic. They were registered at all language levels (phonetic, lexical,morphological, syntactic). A long diagnostic search may be explained by clinical manifestations that are atypical for other cerebrovascular diseases and by the rarity of the disease. PMID:27386589

    Full Text Available INTRODUCTION: Leptospirosis is a zoonotic disease found in tropical and temperate countries, and its clinical diagnostic confusion with arboviruses (dengue fever, oropouche fever and yellow fever, Brazilian spotted fever, viral hepatitis and hantaviruses has been an ongoing public health concern. The aim of this observational study was to demonstrate an association between findings of atypical lymphocytosis and the progression of endemic leptospirosis. METHODS: A retrospective analysis was performed on the demographic, epidemiological, clinical and laboratory aspects of 27 human leptospirosis cases that occurred over a period of 13 years (1996-2009 with no reported epidemic outbreaks in Rio de Janeiro, Brazil. RESULTS: The overall mortality rate was 11.1% in our cohort of hospitalized cases. However, there was no mortality among patients with atypical lymphocytosis (OR = 11.1; 95% CI = 1.12-110.9; p = 0.04. Two patients who were in the septicemic phase showed signs of expansion of γδ T cell responses in peripheral blood. CONCLUSIONS: Atypical lymphocytosis may be observed in patients with leptospirosis. Our observations suggest that these atypical leukocyte subsets are associated with partial protection during the disease course of leptospirosis.

    We describe a 15-mm scirrhous hepatocellular carcinoma (HCC) in a 60-year-old man with B-type cirrhosis. Ultrasound disclosed a 15-mm hypoechoic nodule in segment 7. Contrast-enhanced US revealed heterogeneous, not diffuse, hypervascularity in the early phase and a defect in the Kupffer phase. Contrast-enhanced computed tomography (CT) revealed a heterogeneous hypervascular nodule in the early phase and a low-density area in the late phase. Magnetic resonance imaging (MRI) revealed iso- to hypointensity at T1 and high intensity at T2-weighted sequences. Contrast-enhanced MRI also revealed a heterogeneous hypervascular nodule in the early phase and washout in the late phase. Super-paramagnetic iron oxide-MRI revealed a hyperintense nodule. CT during hepatic arteriography and CT during arterial portography revealed heterogeneous hyperattenuation and a perfusion defect, respectively. Based on these imaging findings the nodule was diagnosed as a mixed well-differentiated and moderately-differentiated HCC. Histologically, the nodule was moderately-differentiated HCC characterized by typical cytological and structural atypia with dense fibrosis. Immunohistochemically, the nodule was positive for heterochromatin protein 1 and alpha-smooth muscle actin, and negative for cytokeratin 19. From the above findings, the nodule was diagnosed as scirrhous HCC. Clinicians engaged in hepatology should exercise caution with suspected scirrhous HCC when imaging studies reveal atypical findings, as shown in our case on the basis of chronic liver disease.

    The treatment of HIV infection has changed dramatically in recent years as a result of the development of new drugs which allows a variety of multitherapy combinations more adapted to patients' needs and thereby improving compliance. Efavirenz is a non-nucleoside reverse transcriptase inhibitor. In addition to a potent antiretroviral activity, efavirenz is an easy-to-take drug with once-daily dosing and is usually well tolerated. Efavirenz, however, may induce psychic alterations which are variable and atypical in both their clinical presentation and severity. As early as the first days of treatment, efavirenz may provoke surprising phenomena such as nightmares, vivid dreams, hallucinations or illusions, and twilight states. Depersonalization and derealization episodes, personality alterations, stream of thought troubles and unusual thought contents, atypical depression and cognitive disorders have also been observed. These phenomena may occur either early or later on treatment. The prevalence of severe psychic disorders is less than 5%, but they are often responsible for harmful treatment discontinuations. Psychiatric side effects are heterogeneous and probably not related to pre-existing psychologic weakness. We do not have enough data to evaluate these side effects and their etiopathogeny. The drug could act directly on the central nervous system since it crosses the blood-brain barrier, on the serotoninergic and dopaminergic systems. Some authors have compared efavirenz-induced psychic effects to those associated with LSD and found structural similarities between the two molecules. However, the heterogeneity and low prevalence of the psychiatric side effects of efavirenz suggest and individual sensitivity. In order to improve patient care, a better clinical approach, neuropsychological evaluation, and functional brain imagery should be used to progress in the analysis and comprehension of these disorders. We discuss in this paper the case of Mister H. This HIV

  2. The genome of Chelonid herpesvirus 5 harbors atypical genes

    The Chelonid fibropapilloma-associated herpesvirus (CFPHV; ChHV5) is believed to be the causative agent of fibropapillomatosis (FP), a neoplastic disease of marine turtles. While clinical signs and pathology of FP are well known, research on ChHV5 has been impeded because no cell culture system for its propagation exists. We have cloned a BAC containing ChHV5 in pTARBAC2.1 and determined its nucleotide sequence. Accordingly, ChHV5 has a type D genome and its predominant gene order is typical for the varicellovirus genus within thealphaherpesvirinae. However, at least four genes that are atypical for an alphaherpesvirus genome were also detected, i.e. two members of the C-type lectin-like domain superfamily (F-lec1, F-lec2), an orthologue to the mouse cytomegalovirus M04 (F-M04) and a viral sialyltransferase (F-sial). Four lines of evidence suggest that these atypical genes are truly part of the ChHV5 genome: (1) the pTARBAC insertion interrupted the UL52 ORF, leaving parts of the gene to either side of the insertion and suggesting that an intact molecule had been cloned. (2) Using FP-associated UL52 (F-UL52) as an anchor and the BAC-derived sequences as a means to generate primers, overlapping PCR was performed with tumor-derived DNA as template, which confirmed the presence of the same stretch of “atypical” DNA in independent FP cases. (3) Pyrosequencing of DNA from independent tumors did not reveal previously undetected viral sequences, suggesting that no apparent loss of viral sequence had happened due to the cloning strategy. (4) The simultaneous presence of previously known ChHV5 sequences and F-sial as well as F-M04 sequences was also confirmed in geographically distinct Australian cases of FP. Finally, transcripts of F-sial and F-M04 but not transcripts of lytic viral genes were detected in tumors from Hawaiian FP-cases. Therefore, we suggest that F-sial and F-M04 may play a role in FP pathogenesis

    We retrospectively analysed the clinical and CT findings of 24 cases with tuberous sclerosis with special emphasis upon the atypical presentation. The cases with classic clinical triad were accounted for in 21%, while 33% presented with atypical clinical features. The most common and characteristic CT finding is that of the subependymal calcified nodules of the lateral ventricle, which was seen in 85% of our cases. Cortical tuber and white matter lesions were demonstrated in 65% and 55%, respectively. Three cases showed cortical tuber and white matter lesion without subependymal tuber. The cortical tuber usually exhibited low density or calcified lesion, but showed high density in 2 cases. Other findings of tuberous sclerosis included intraventricular tumor, ventriculomegaly, and cortical atrophy. One case clearly demonstrated parenchymal tuber on MR imaging. In conclusion, diagnosis of tuberous sclerosis is usually made on the clinical bases initially. However, CT and MR are also diagnostic even in unusual clinical presentation such as unexplained retardation or epilepsy or when the classic clinical triad is incomplete. If only cortical tuber or white matter lesion is present, it is difficult to diagnose tuberous sclerosis and to differentiate from other cortical mass lesion. Therefore, careful evaluation is required with familiarity with the atypical appearance of the disease.

    According to the classification of Mitsuda, 23 patients with endogenous psychosis aged 40 years or younger, presenting with hallucination and delusion, were classified as having schizophrenia (n=12) or atypical psychosis (n=11). These patients were studied by single photon emission computed tomography (SPECT) with N-isopropyl-p-I-123-iodoamphetamine (I-123 IMP). Sixteen healthy persons served as controls. Early and delayed SPECT images were obtained 30 min and 4 hr, respectively, after intravenous injection of I-123 IMP. The group of schizophrenic patients had markedly decreased uptake of I-123 in the basal ganglia, as well as the right temporal and left occipital areas on both early and delayed images. In the group of atypical psychosis patients, however, decreased uptake of I-123 was noted in both the right basal ganglia and left occipital area on early images, but none of such findings were seen on delayed images. Regarding the uptake ratio in the frontal area on both early and delayed images, there were significant differences between the two groups. These findings have important implications for the different etiology of both disease types: not only functional disturbance in the frontal area but also irreversible changes may be involved in the occurrence of schizophrenia, and functional disturbance particularly in the right basal ganglia may be involved in the occurrence of atypical psychosis.

    Among the spectrum of disease manifestations associated with systemic lupus erythematosus, lupus nephritis is particularly concerning due to the potential for renal failure. This autoimmune attack may not, however, be limited to the kidney and is increasingly being recognized as a trigger for atypical Hemolytic Uremic Syndrome (aHUS). Atypical HUS falls under the spectrum of the thrombotic microangiopathies (TMAs) – a group of disorders characterized by microangiopathic hemolytic anemia, thrombocytopenia, and end organ damage. Although plasma exchange is considered first-line therapy for thrombotic thrombocytopenic purpura – a TMA classically associated with autoimmune depletion of ADAMTS-13 – aHUS demonstrates less reliable responsiveness to this modality. Instead, use of the late complement inhibitor Eculizumab has emerged as an effective modality for the management of such patients. Diagnosis of aHUS, however, is largely clinically based, relying heavily upon a multidisciplinary approach. Herein we present the case of a patient with atypical HUS successfully treated with Eculizumab in the setting of Class IV-G (A) lupus nephritis and hypocomplementemia.

    C-reactive protein (CRP) is an acute-phase reactant that increases in the circulation in response to a variety of inflammatory stimuli. Elevated levels in serum during several infectious diseases have been reported. In this study, a highly sensitive CRP enzyme immunoassay was used to evaluate serum CRP values in patients with viral and atypical bacterial infections. Patients (n = 139) with different viral or atypical bacterial infections (systemic or respiratory) and healthy controls (n = 40) were tested for circulating CRP values. High levels of IgM antibodies against several viruses: Dengue virus (n = 36), Cytomegalovirus (n = 9), Epstein Barr virus (n = 17), Parvovirus B19 (n = 26), Herpes simplex 1 and 2 virus (n = 3) and Influenza A and B (n = 8) and against atypical bacteria: Legionella pneumophila (n = 15), Mycoplasma pneumoniae (n = 21) and Coxiella burnetii (n = 4) were found. High values of CRP in infected patients compared with controls (P < 0.001) were found; however, no significant differences between viral and atypical bacterial infections were found. Low levels of CRP in respiratory and Coxiella burnetii infections compared with exanthematic viral and other atypical bacterial infections were found. This study suggests that CRP values are useful to define viral and atypical bacterial infections compared with normal values, but, it is not useful to define type of infection. PMID:26241406

    Full Text Available Previous research has shown an association between emotions, particularly social emotions, and moral judgments. Some studies suggested an association between blunted emotion and the utilitarian moral judgments observed in patients with prefrontal lesions. In order to investigate how prefrontal brain damage affects moral judgment, we asked a sample of 29 TBI patients (12 females and 17 males and 41 healthy participants (16 females and 25 males to judge 22 hypothetical dilemmas split into three different categories (non-moral, impersonal and personal moral. The TBI group presented a higher proportion of affirmative (utilitarian responses for personal moral dilemmas when compared to controls, suggesting an atypical pattern of utilitarian judgements. We also found a negative association between the performance on recognition of social emotions and the proportion of affirmative responses on personal moral dilemmas. These results suggested that the preference for utilitarian responses in this type of dilemmas is accompanied by difficulties in social emotion recognition. Overall, our findings suggest that deontological moral judgments are associated with normal social emotion processing and that frontal lobe plays an important role in both emotion and moral judgment.

    BACKGROUND: Focal nodular hyperplasia, a benign hepatic tumor, is usually asymptomatic. However, rarely the entity can cause symptoms, mandating intervention. METHOD: We present a case of focal nodular hyperplasia of the liver, which caused a considerable diagnostic dilemma due to its atypical presentation. RESULTS: A 29-year-old woman presented with a 15-year history of a progressively increasing mass in the right upper quadrant which was associated with pain and emesis. Examination showed a firm, mobile mass palpable below the right subcostal margin. A computed tomography scan of the abdomen showed an exophytic mass arising from hepatic segments III and IVb. Trucut biopsy of the hepatic mass was equivocal. Angiography showed a vascular tumor that was supplied by a tortuous branch of the proper hepatic artery. Surgical intervention for removal of the mass was undertaken. Intra-operatively, two large discrete tumors were found and completely resected. Histopathological examination showed features consistent with focal nodular hyperplasia. CONCLUSION: This description of an unusual case of focal nodular hyperplasia of the liver highlights the point that the diagnosis of otherwise benign hepatic tumors may be difficult despite extensive work-up in some cases.

    2006-03-01

    Full Text Available Abstract Celiac disease is a chronic intestinal disease caused by intolerance to gluten. It is characterized by immune-mediated enteropathy, associated with maldigestion and malabsorption of most nutrients and vitamins. In predisposed individuals, the ingestion of gluten-containing food such as wheat and rye induces a flat jejunal mucosa with infiltration of lymphocytes. The main symptoms are: stomach pain, gas, and bloating, diarrhea, weight loss, anemia, edema, bone or joint pain. Prevalence for clinically overt celiac disease varies from 1:270 in Finland to 1:5000 in North America. Since celiac disease can be asymptomatic, most subjects are not diagnosed or they can present with atypical symptoms. Furthermore, severe inflammation of the small bowel can be present without any gastrointestinal symptoms. The diagnosis should be made early since celiac disease causes growth retardation in untreated children and atypical symptoms like infertility or neurological symptoms. Diagnosis requires endoscopy with jejunal biopsy. In addition, tissue-transglutaminase antibodies are important to confirm the diagnosis since there are other diseases which can mimic celiac disease. The exact cause of celiac disease is unknown but is thought to be primarily immune mediated (tissue-transglutaminase autoantigen; often the disease is inherited. Management consists in life long withdrawal of dietary gluten, which leads to significant clinical and histological improvement. However, complete normalization of histology can take years.

    Full Text Available With the rapid increase in patients receiving bisphosphonates (BPs for treating osteoporosis, one of the clinical complications associated with its long-term use is atypical femoral fractures (AFFs. Although the absolute risk for AFFs is low and it was a consensus that AFFs were acceptable compared with the amount of osteoporotic fractures BPs have prevented, epidemiological studies have proved that BPs had a strong association with AFFs and possibly more people were going to suffer from this adverse effect with wide prescriptions of this drug. In addition, AFFs seemed to have impaired ability to heal. Thus, to understand the mechanism(s behind AFFs is important and desirable for considering preventive measures. This article reviewed the clinical features of AFFs as well as potential underlining pathological characteristics, such as the decreased turnover rate caused by BPs that led to multiple-level alternations, e.g., changes not only at cellular and tissue levels, but also related to changes in bone micro- and macrostructure and organic/inorganic contents, leading to potentially compromised mechanical properties of cortical bone when exposed to prolonged BP therapy. Severely suppressed bone turnover may also be the underlying mechanism for impaired fracture healing in patients with AFFs. The rising concerns about the risk for AFFs in nonosteoporotic patients receiving high-dose BPs to treat cancers were also discussed. Detailed investigation will help develop potential targeted pharmacological treatments such as parathyroid hormone. In addition, potential innovative internal fixation implants were discussed with regard to dynamic and biological fixation for enhancing AFF repair.

    Xeroderma pigmentosum (XP) is a rare, autosomal recessive disease involving a defect in DNA repair leading to the premature development of numerous aggressive cutaneous malignancies. Although atypical fibroxanthoma (AFX) is a neoplasm typically found in the setting of extensive sun exposure or therapeutic radiation, AFXs are rarely associated with children with XP. We report the case of a 13-year-old Guatemalan girl with the XP type C variant who developed one of the largest AFXs reported on a child's finger. PMID:27046537

    Whether a brain abscess is apparent by imaging depends on the stage of the abscess at the time of imaging, as well as the etiology of the infection. Because conventional magnetic resonance imaging (MRI) is limited in its ability to distinguish brain abscesses from necrotic tumors, advanced techniques are required. The management of these two disease entities differs and can potentially affect the clinical outcome. We report a case having atypical imaging features of a pyogenic brain abscess on advanced MRI, in particular, on diffusion-weighted and perfusion imaging, in a patient with osteosarcoma undergoing chemotherapy.

    Full Text Available Abstract Background Mucopolysaccharidoses are heritable, metabolic diseases caused by deficiency in an activity of one of specific lysosomal enzymes involved in degradation of mucoplysaccharides (glycosaminoglycans. Among many medical problems of patients with mucopolysaccharidoses, there are frequent episodes of diarrhea of unknown etiology. Case presentation A girl, diagnosed enzymatically for mucopolysaccharidosis type I (deficiency of α-L-iduronidase at the age of 3 years and 9 months, was investigated until the age of 5 years and 4 months. Frequent loose stools and episodes of diarrhea, often accompanied by vomiting, were encountered. Detailed microbiological analyses were performed and atypical microbial infections (most often enetropathogenic Escherichia coli, but also other species, like Pseudomonas aeruginosa or Staphylococcus aureus, as well as adenoviruses of the digestive tract were found in most severe diarrhea episodes. Often, isolations of pathogenic bacterial strains from stools of the investigated patient suffering from diarrhea were not obvious during the first screening, and only detailed microbiological studies, including re-isolation of colonies, gave the results of isolation of particular pathogenic strains (especially in the case of enetropathogenic E. coli. Conclusion We conclude that atypical microbial infections of digestive tract may contribute significantly to diarrhea in mucopolysaccaridosis patients. Since isolated strains were not typical and their isolation was often possible only after detailed investigation (not during a standard screening, such atypical microbial infections of digestive tract of mucopolysaccharidosis patients could be usually overlooked to date. Importantly, these atypical infections could be effectively treated with antimicrobial agents.

    Piodermal gangrenosum (PG) is an uncommon ulcerative cutaneous dermatosis associated with a variety of systemic diseases,including inflammatory bowel disease (IBD),arthritis,leukaemia,hepatitis,and primary billiary cirrhosis.Other cutaneous ulceration resembling PG had been described in literature.There has been neither laboratory finding nor histological feature diagnostic of PG,and diagnosis of PG is mainly made based on the exclusion criteria.We present here a patient,with ulcerative colitis (UC)who was referred to the emergency section with a large and rapidly evolving cutaneous ulceration.Laboratory and microbiological investigation associated with histological findings of the ulcer specimen allowed us to exclude autoimmune and systemic diseases as well as immuno-proliferative disorders.An atypical presentation of PG with UC was diagnosed.Pulse boluses of i.v.methyl-prednisolone were started,and after tapering steroids,complete resolution of the skin lesion was achieved in 3 wk.The unusual rapid healing of the skin ulceration with steroid mono-therapy and the atypical cutaneous presentation in this patient as well as the risk of misdiagnosis of PG in the clinical practice were discussed.

  20. The usefulness of SPECT and MRI in the diagnosis of atypical parkinsonian syndromes

    International Nuclear Information System (INIS)

    Clinico-pathological studies have shown that only three out of four patients with parkinsonism have idiopathic Parkinson's disease. In patients with so-called Parkinson plus syndrome, the degeneration in the brain is more widespread and the variety of neurological signs greater than in Parkinson's disease. The differentiation of these syndromes from Parkinson's disease can be difficult. Single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRl) can be of value in the differential diagnosis of parkinsonism. We present three patients with atypical parkinsonism in whom MRI and SPECT with β-CIT and epidepride was performed in addition to the clinical evaluation. The three patients all had a rapidly developing symmetric akinetic-rigid syndrome that responded poorly to levodopa. MRI showed findings regarded as typical for multiple system atrophy in two patients, but only nonspecific findings in the third patient. SPECT with β-CIT showed a pronounced bilateral and relatively symmetric reduction in the striatal dopaminergic activity in all patients. SPECT with epidepride showed a clearly reduced striatal D2-receptor binding bilaterally in only one of the patients. In patients with atypical parkinsonism, MRI and SPECT with β-CIT and epidepride can give valuable support to the clinical diagnosis of a Parkinson plus syndrome

    The benefits of bisphosphonates are well documented, but prolonged use has been associated with atypical femur fractures. Radiographic markers for fracture predisposition could potentially aid in safer medication use. In this case-control designed study, we compared hip radiographic parameters and the demographic characteristics of chronic bisphosphonate users who sustained an atypical femoral fracture with a group of chronic bisphosphonate users who did not sustain an atypical femur fracture and also a group who sustained an intertrochanteric hip fracture. Radiographic parameters included were neck-shaft angle (NSA), hip-axis length (HAL) and center-edge angle (CE). Multivariate regression was used to evaluate the relationship between radiographic measures and femur fracture. Receiver-operating characteristic analysis determined cut-off points for neck-shaft angle and risk of atypical femur fracture. Ultimately, pre-fracture radiographs of 53 bisphosphonate users who developed atypical fracture were compared with 43 asymptomatic chronic bisphosphonate users and 64 intertrochanteric fracture patients. Duration of bisphosphonate use did not statistically differ between users sustaining atypical fracture and those without fracture (7.9 [±3.5] vs. 7.7 [±3.3] years, p=0.7). Bisphosphonate users who fractured had acute/varus pre-fracture neck-shaft angles (p<0.001), shorter hip-axis length (p<0.01), and narrower center-edge angles (p<0.01). Regression analysis revealed associations between neck-shaft angle (OR=0.89 [95% CI=0.81-0.97; p=0.01), center edge angle (OR=0.89 [95% CI=0.80-0.99]; p=0.03), and BMI (OR=1.15 [95% CI=1.02-1.31; p=0.03) with fracture development. ROC curve analysis (AUC=0.67 [95% CI=0.56-0.79]) determined that a cut-off point for neck-shaft angle <128.3° yielded 69% sensitivity and 63% specificity for development of atypical femoral fracture. Ultimately, an acute/varus angle of the femoral neck, high BMI, and narrow center-edge angle were

    Prion diseases, such as bovine spongiform encephalopathies (BSE), are transmissible neurodegenerative disorders affecting humans and a wide variety of mammals. Variant Creutzfeldt-Jakob disease (vCJD), a prion disease in humans, has been linked to exposure to BSE prions. This classical BSE (cBSE) is now rapidly disappearing as a result of appropriate measures to control animal feeding. Besides cBSE, two atypical forms (named H- and L-type BSE) have recently been described in Europe, Japan, and North America. Here we describe the first wide-spectrum microarray analysis in whole blood of atypical BSE-infected cattle. Transcriptome changes in infected animals were analyzed prior to and after the onset of clinical signs. The microarray analysis revealed gene expression changes in blood prior to the appearance of the clinical signs and during the progression of the disease. A set of 32 differentially expressed genes was found to be in common between clinical and preclinical stages and showed a very similar expression pattern in the two phases. A 22-gene signature showed an oscillating pattern of expression, being differentially expressed in the preclinical stage and then going back to control levels in the symptomatic phase. One gene, SEL1L3, was downregulated during the progression of the disease. Most of the studies performed up to date utilized various tissues, which are not suitable for a rapid analysis of infected animals and patients. Our findings suggest the intriguing possibility to take advantage of whole blood RNA transcriptional profiling for the preclinical identification of prion infection. Further, this study highlighted several pathways, such as immune response and metabolism that may play an important role in peripheral prion pathogenesis. Finally, the gene expression changes identified in the present study may be further investigated as a fingerprint for monitoring the progression of disease and for developing targeted therapeutic interventions.

  6. EPR dosimetry with synthetic A-type carbonated apatite

    International Nuclear Information System (INIS)

    Synthetic A-type carbonated apatite prepared in reproducible conditions were irradiated at room temperature with 60 Co γ rays. The EPR spectrum is associated to axial CO2- and orthorhombic CO3- species. Radicals used as dose marker in biological apatite are long live paramagnetic species. The stability of the post-irradiation signal of A-type apatite was investigated for more than one year. Measurements showed variations in the spectra attributed to unstable CO3- species, which can be eliminated by thermal treatments at 100 deg C for 24 hours. The CO2- spectrum can be identified in samples irradiated up to 0.2 Gy. All results indicate the A-type apatite as an appropriate material for radiotherapy dosimetry. (author)

    Full Text Available Background. Atypical forms of pyoderma gangrenosum generally appear on the upper extremities; most frequently they are associated with myeloproliferative disorders, including osteomyelofibrosis. A response to systemic steroids is more pronounced than in classical form. Sometimes it may be the first sign of an underlying malignancy. Case report. We reported a patient with atypical pyoderma gangrenosum developed during the course of a myeloid malignancy - osteomyelofibrosis. The lesions occurred after a minor trauma. Painful blistering plaques, with an elevated, bluish-gray border were located on the dorsal aspect of hands. No skin malignancy was found. The lesions resolved rapidly to systemic steroids. Conclusion. Considering the unusual clinical presentation which makes the diagnosis difficult, as well as the fact that atypical forms of pyoderma gangrenosum can be the first sign of malignancies, especially myeloproliferative ones, recognizing this entity enables timely guiding future investigations toward their prompt detection.

  8. Atypical femur fractures associated with bisphosphonates: from prodrome to resolution

    Full Text Available Atypical fractures related to the prolonged use of bisphosphonates are caused by low energy mechanisms and are characterized by oblique and transverse lines and frequent bilateralism. We present a clinical case of a patient who we believe illustrates, both in clinical and radiological aspects, the new definition of atypical femur fracture related to treatment using bisphosphonates treated conservatively and successfully with discharge and teriparatide 20 mcg/80 mcl s.c./24h. The appearance of painful symptoms in the upper thigh, especially if bilateral, in patients treated with bisphosphonates for long periods of time, makes it necessary to dismiss bone lesions that might otherwise suggest atypical fracture. In those cases where the fracture is incomplete, restoring bone metabolism through the administration of teriparatide 20 mcg/80 mcl s.c./24h could prevent displaced fractures.

    Full Text Available Neuroleptic malignant syndrome (NMS is the most serious of acute neurological side effects produced by antipsychotic medication, characterized by hyperthermia, rigidity, altered consciousness and autonomic dysfunction, the prevalence of which varies from 0.4-1.4%. NMS is usually seen in treatment with high potency typical antipsychotics and very rarely with atypical antipsychotics. However, NMS cases have been reported with risperidone, clozapine, olanzapine and quetiapine. The presentations of NMS have often varied, and we report another atypicality in presentation of NMS due to olanzapine use.

    Full Text Available Calprotectin (CP is a calcium- and zinc-binding protein of the S100 family expressed mainly by neutrophils with important extracellular activity. The aim of the current review is to summarize the latest findings concerning the role of CP in a diverse range of inflammatory and noninflammatory conditions among children. Increasing evidence suggests the implication of CP in the diagnosis, followup, assessment of relapses, and response to treatment in pediatric pathological conditions, such as inflammatory bowel disease, necrotizing enterocolitis, celiac disease, intestinal cystic fibrosis, acute appendicitis, juvenile idiopathic arthritis, Kawasaki disease, polymyositis-dermatomyositis, glomerulonephritis, IgA nephropathy, malaria, HIV infection, hyperzincemia and hypercalprotectinemia, and cancer. Further studies are required to provide insights into the actual role of CP in these pathological processes in pediatrics.

    Atmospheric concentrations of {sup 212}Pb were observed with aerosol samples during the period from June, 1999 to December, 2000 at Kawasaki. The atmospheric concentrations of {sup 212}Pb ranged from 20 to 130 mBq/m{sup 3}. Seasonal variations in {sup 212}Pb concentration showed the ''one-peak'' variation pattern: high concentrations appeared in winter season. The atmospheric concentration of {sup 212}Pb and SO{sub 2} after the eruption of Miyake-jima volcano on Aug. 29, 2000 were higher than average value in the season. After the eruption, the variation in the concentration of SO{sub 2} correlates with that of {sup 212}Pb. The atmospheric concentration of {sup 212}Pb showed an unusual and temporal increase in the period from late August to early September, 2000, being inferred to be attributed partly to the {sup 212}Pb fallout originating from the 2000 eruption of Miyake jima volcano, Japan.

    Bariatric surgery dramatically alters the normal stomach anatomy resulting in a significant incidence of hiatal hernia and gastroesophageal reflux disease. Although the majority of patients remain asymptomatic, many complain of severe heartburn refractory to medical management and additional highly atypical symptoms. Here, we describe the diagnosis and treatment regarding four cases of symptomatic hiatal hernia following bariatric surgery presenting with atypical symptoms in the University Hospital, USA. Four patients presented following laparoscopic Roux-en-Y gastric bypass or duodenal switch/pancreaticobiliary bypass (DS) with disabling and intractable midepigastric abdominal pain characterized as severe and radiating to the jaw, left shoulder, and midscapular area. The pain in all cases was described as paroxysmal and not necessarily associated with eating. All four patients also experienced nausea, vomiting, and failure to thrive at various intervals following laparoscopic bariatric surgery. Routine workup failed to produce any clear mechanical cause of these symptoms. However, complimentary use of multidetector CT and upper gastrointestinal contrast studies eventually revealed the diagnosis of hiatal hernia. Exploration identified the presence of a type I hiatal hernia in all four patients, with the stomach staple lines densely adherent to the diaphragm and parietal peritoneum. Operative intervention led to immediate and complete resolution of symptoms. The presence of a hiatal hernia following bariatric surgery can present with highly atypical symptoms that do not resolve without operative intervention. Recognition of this problem should lead to the consideration of surgery in cases where patients are dependent on artificial nutritional support and whose symptoms are poorly controlled with medication alone.

    Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a distinct Hodgkin lymphoma subtype composed of few neoplastic lymphocyte-predominant (LP) cells in a background of reactive small B and T cells. We have seen occasional NLPHL cases that contain background T cells with prominent cytologic atypia, raising the differential diagnosis of peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) or a composite lymphoma. We sought to characterize the clinicopathologic features of such cases. Eleven NLPHL cases with atypical T cells diagnosed from 1977 to 2010 were identified at 2 institutions and compared with 24 control NLPHL cases lacking atypical T cells. All 9 male patients and 2 female patients presented with localized peripheral lymphadenopathy. In comparison with control patients, they were younger (median age, 13.8 vs. 36.1 y; P=0.015), with more frequent cervical lymph node involvement (54.5% vs. 8.3%, P=0.015). In all 11 cases, areas of NLPHL with typical B-cell-rich nodules containing LP cells were present. Nine cases contained sheets of atypical T cells surrounding primary and secondary follicles in a pattern mimicking the T-zone pattern of PTCL-NOS; the remaining 2 cases contained atypical T cells presented as large clusters at the periphery of B-cell-rich nodules. In all cases, the atypical T-cell-rich areas contained rare scattered LP cells, which were IgD in 5 of 7 cases (71.4%). The atypical T cells showed no pan-T-cell antigen loss or aberrant T-cell antigen expression in any case, and polymerase chain reaction or Southern blot analysis showed no evidence of T-cell clonality in 6 cases tested. The atypical T cells exhibited a variable immunophenotype with respect to germinal center, follicular T-helper, T-regulatory, and cytotoxic T-cell markers. Among 8 patients with clinical follow-up (median follow-up: 6.4 y), 5 patients had recurrent NLPHL at 6 months to 12 years after diagnosis and 6 patients are alive without disease at 9 months to 18

    Humic substances are formed during the decomposition of organic matter in humus, and are found in many natural environments in which organic materials and microorganisms have been present. In the present study, oral administration of humus extract to common carp (Cyprinus carpio L.) induced effective protection against experimental atypical Aeromonas salmonicida infection. Mortality of fish and development of skin lesions such as hemorrhages and ulcers were significantly suppressed in carp treated with 10%, 5% or 1% humus extract adsorbed on dry feeding pellets. The median surviving days was also greater in fish treated with 10% or 5% humus extract than in untreated fish. Atypical A. salmonicida was isolated from ulcerative lesions of part of dead fish, but Aeromonas hydrophila and Flavobacterium sp. were also isolated from these fish, verifying bacterial population changes during the progression of skin lesions. These results clearly show that treatment of fish with humus extract is effective in preventing A. salmonicida disease.

    Full Text Available Aim: To explore the methods for achieving pain relief in patients with atypical trigeminal neuralgia (TN using microvascular decompression (MVD. Study Design and Settings: Retrospective study of 26 patients treated during the years 2000 to 2004. Materials and Methods: Twenty-six patients in whom vascular compression of the trigeminal nerve was identified by high definition magnetic resonance tomographic angiography (MRTA were treated with MVD for atypical TN in our department. Clinical presentations, surgical findings and clinical outcomes were analyzed retrospectively. Results: In this study, single trigeminal division was involved in only 2 patients (8% and two or three divisions in the other 24 patients (92%. Of prime importance is the fact that in 46.2% of the patients, several conflicting vessels were found in association. Location of the conflicts around the circumference of the trigeminal root was supero-medial to the root in 53.5%, supero-lateral in 30.8% and inferior in 15.7%. MVD for atypical TN resulted in complete pain relief in 50% of the patients with complete decompression, partial pain relief in 30.8% and poor pain relief or pain recurrence in 19.2% of the patients without complete decompression postoperatively. Conclusions: Complete decompression of the entire trigeminal root plays an important role in achieving pain relief in patients with atypical TN with MVD.

    Full Text Available Hereditary Haemorrhagic Telangiectasia (Osler-Rendu-Weber disease is a rare autosomal dominant disorder commonly a ecting small vessels of skin and mucosa. It is usually misdiagnosed because of its atypical presentation. This disease frequently presents as epistaxis, GI bleed and visceral arterio venous malformations. Patient may present with stroke or migraine but presentation due to predominant respiratory symptoms may occur in the presence of pulmonary A-V stula. We present a 9 yr old male with dyspnoea on exertion and cyanosis and clubbing. He had a past history of intracerebral bleed with thrombocytopenia and he was being treated as ITP. Contrast echo revealed ndings suggestive of pulmonary arterio venous stula which led to subsequent investigations and retrospective evaluation and hence achieving the final diagnosis.

    Full Text Available A large kindred of familial pulmonary fibrosis is reported. Six members from the first two generations of this particular kindred were described more than 40 years previously; six more individuals from the third and fourth generations have also been evaluated. The proband, now 23 years of age, has mild disease; the other 11 documented affected family members all died from their disease at an average age of 37 years (range 25 to 50 years. The pathology was that of usual interstitial pneumonia, as is typical in idiopathic pulmonary fibrosis. However, the initial radiographic pattern in many of these individuals was upper lobe and nodular and, along with the young age, was atypical for idiopathic pulmonary fibrosis. Several genetic abnormalities have been associated with familial pulmonary fibrosis. The present study examined the genes coding for surfactant protein-C, ATP-binding cassette protein A3 and telomerase, and found no abnormalities.

  7. Discovering disease associations by integrating electronic clinical data and medical literature.

    Antony B Holmes

    Full Text Available Electronic health record (EHR systems offer an exceptional opportunity for studying many diseases and their associated medical conditions within a population. The increasing number of clinical record entries that have become available electronically provides access to rich, large sets of patients' longitudinal medical information. By integrating and comparing relations found in the EHRs with those already reported in the literature, we are able to verify existing and to identify rare or novel associations. Of particular interest is the identification of rare disease co-morbidities, where the small numbers of diagnosed patients make robust statistical analysis difficult. Here, we introduce ADAMS, an Application for Discovering Disease Associations using Multiple Sources, which contains various statistical and language processing operations. We apply ADAMS to the New York-Presbyterian Hospital's EHR to combine the information from the relational diagnosis tables and textual discharge summaries with those from PubMed and Wikipedia in order to investigate the co-morbidities of the rare diseases Kaposi sarcoma, toxoplasmosis, and Kawasaki disease. In addition to finding well-known characteristics of diseases, ADAMS can identify rare or previously unreported associations. In particular, we report a statistically significant association between Kawasaki disease and diagnosis of autistic disorder.

    Dual-specificity phosphatases (DSPs) constitute a large protein tyrosine phosphatase (PTP) family, with examples in distant evolutive phyla. PFA-DSPs (Plant and Fungi Atypical DSPs) are a group of atypical DSPs present in plants, fungi, kinetoplastids, and slime molds, the members of which share structural similarity with atypical- and lipid phosphatase DSPs from mammals. The analysis of the PFA-DSPs from the plant Arabidopsis thaliana (AtPFA-DSPs) showed differential tissue mRNA expression, substrate specificity, and catalytic activity for these proteins, suggesting different functional roles among plant PFA-DSPs. Bioinformatic analysis revealed the existence of novel PFA-DSP-related proteins in fungi (Oca1, Oca2, Oca4 and Oca6 in Saccharomyces cerevisiae) and protozoa, which were segregated from plant PFA-DSPs. The closest yeast homolog for these proteins was the PFA-DSP from S. cerevisiae ScPFA-DSP1/Siw14/Oca3. Oca1, Oca2, Siw14/Oca3, Oca4, and Oca6 were involved in the yeast response to caffeine and rapamycin stresses. Siw14/Oca3 was an active phosphatase in vitro, whereas no phosphatase activity could be detected for Oca1. Remarkably, overexpression of Siw14/Oca3 suppressed the caffeine sensitivity of oca1, oca2, oca4, and oca6 deleted strains, indicating a genetic linkage and suggesting a functional relationship for these proteins. Functional studies on mutations targeting putative catalytic residues from the A. thaliana AtPFA-DSP1/At1g05000 protein indicated the absence of canonical amino acids acting as the general acid/base in the phosphor-ester hydrolysis, which suggests a specific mechanism of reaction for PFA-DSPs and related enzymes. Our studies demonstrate the existence of novel phosphatase protein families in fungi and protozoa, with active and inactive enzymes linked in common signaling pathways. This illustrates the catalytic and functional complexity of the expanding family of atypical dual-specificity phosphatases in non-metazoans, including

    Science.gov (United States)

    Miyata, Shigeki; Maeda, Takuma

    2016-03-01

    Heparin-induced thrombocytopenia (HIT) is a prothrombotic side effect of heparin therapy caused by HIT antibodies, i.e., anti-platelet factor 4 (PF4)/heparin IgG with platelet-activating properties. For serological diagnosis, antigen immunoassays are commonly used worldwide. However, such assays do not indicate their platelet-activating properties, leading to low specificity for the HIT diagnosis. Therefore, over-diagnosis is currently the most serious problem associated with HIT. The detection of platelet-activating antibodies using a washed platelet activation assay is crucial for appropriate HIT diagnosis. Recent advances in our understanding of the pathogenesis of HIT include it having several clinical features atypical for an immune-mediated disease. Heparin-naïve patients can develop IgG antibodies as early as day 4, as in a secondary immune response. Evidence for an anamnestic response on heparin re-exposure is lacking. In addition, HIT antibodies are relatively short-lived, unlike those in a secondary immune response. These lines of evidence suggest that the mechanisms underlying HIT antibody formation may be compatible with a non-T cell-dependent immune reaction. These atypical clinical and serological features should be carefully considered while endeavoring to accurately diagnose HIT, which leads to appropriate therapies such as immediate administration of an alternative anticoagulant to prevent thromboembolic events and re-administration of heparin during surgery involving cardiopulmonary bypass when HIT antibodies are no longer detectable.

    Full Text Available Abstract Background Severe hypertriglyceridaemia (HTG is uncommon but most prevalent in subjects with type 2 diabetes mellitus (T2DM and excess ethanol intake. Case presentation We describe a case of a middle age male (53 y presenting to the emergency room with acute atypical central chest pain and severe HTG in the absence of evidence of overt ischaemic heart disease (IHD. Admission ECG and EET (exercise tolerance test were negative for reversible ischaemic changes. His admission glucose was 12.2 mmol/l, triglycerides (TG were 103 mmol/l, total cholesterol 37 mmol/l. Cardiac Troponin T could not be measured on three occasions but CK MB mass was normal at 3 μg/l. The patient was started on Bezafibrate 400 mg OD, Simvastatin 20 mg nocte, Omacor (Omega-3 fish oil 1 gm bd and Metformin 500 mg tds. Four weeks after admission, lipid and liver profiles showed remarkable improvement, TG 2.9 mmol/l, Tchol 6.3 mmol/l and HDLc 1.5 mmol/l, ALAT and GGT were normal. Conclusion A case report of severe hypertriglyceridaemia with atypical presentation demonstrate the role of combined lipid modifying agents in lowering triglycerides and cholesterol as well as improving liver enzymes.

    Full Text Available Rhinosinusitis affects approximately 20% of the population, and the chronic rhinosinusitis represents over 90% of all cases of rhinosinusitis. The correct diagnosis is important for proper treatment and to predict its evolution. This study presents two cases of atypical frontal sinus disease, which the follow-up revealed a diagnosis of fungal rhinosinusitis. The present study aims to describe the cases of two patients with atypical lesions on the left frontal sinus; the treatment options, surgical approach, results, diagnosis and follow-up are further discussed. A significant increase in the reported cases of fungal rhinosinusitis has been seen in the last two decades, justified by the use of broad-spectrum antibiotics and steroids, as well as the increased number of immunocompromised individuals. This study reports the cases of two patients with a type of fungal rhinosinusitis named "fungal ball", characterized by a tangle of hyphae in the sinuses without tissue invasion. The treatment included surgical removal of the fungal infectious process with aeration of the affected sinus, and the procedure was successfully performed in our patients.

    Full Text Available Abstract A male patient, born to unrelated Belgian parents, presented at 4 months with epistaxis, haematemesis and haematochezia. On physical examination he presented petechiae and haematomas, and a slightly enlarged liver. Serum transaminases were elevated to 5-10 times upper limit of normal, alkaline phosphatases were 1685 U/L (180 s ( Fumarylacetoacetase (FAH protein and activity in cultured fibroblasts and liver tissue were decreased but not absent. 4-hydroxyphenylpyruvate dioxygenase activity in liver was normal, which is atypical for tyrosinemia type I. A novel mutation was found in the FAH gene: c.103G>A (Ala35Thr. In vitro expression studies showed this mutation results in a strongly decreased FAH protein expression. Dietary treatment with phenylalanine and tyrosine restriction was initiated at 4 months, leading to complete clinical and biochemical normalisation. The patient, currently aged 12 years, shows a normal physical and psychomotor development. This is the first report of mild tyrosinemia type I disease caused by an Ala35Thr mutation in the FAH gene, presenting atypically without increase of the diagnostically important toxic metabolites succinylacetone and succinylacetoacetate.

    Systemic autoimmune diseases (SADs) are a significant cause of morbidity and mortality worldwide, although their epidemiological profile varies significantly country by country. We explored the potential of the Google search engine to collect and merge large series (>1000 patients) of SADs reported in the Pubmed library, with the aim of obtaining a high-definition geoepidemiological picture of each disease. We collected data from 394,827 patients with SADs. Analysis showed a predominance of medical vs. administrative databases (74% vs. 26%), public health system vs. health insurance resources (88% vs. 12%) and patient-based vs. population-based designs (82% vs. 18%). The most unbalanced gender ratio was found in primary Sjögren syndrome (pSS), with nearly 10 females affected per 1 male, followed by systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and antiphospholipid syndrome (APS) (ratio of nearly 5:1). Each disease predominantly affects a specific age group: children (Kawasaki disease, primary immunodeficiencies and Schonlein-Henoch disease), young people (SLE Behçet disease and sarcoidosis), middle-aged people (SSc, vasculitis and pSS) and the elderly (amyloidosis, polymyalgia rheumatica, and giant cell arteritis). We found significant differences in the geographical distribution of studies for each disease, and a higher frequency of the three SADs with available data (SLE, inflammatory myopathies and Kawasaki disease) in African-American patients. Using a "big data" approach enabled hitherto unseen connections in SADs to emerge. PMID:25842074

    Full Text Available Atypical swallowing is the persistence of childlike deglutition at the end of dental eruption. One of the main causes is macroglossia, that is the abnormal enlargement of the tongue. The treatment is logopedic and/or surgical. Children with macroglossia have an increased incidence of respiratory diseases and infections, as well as malocclusions, articulatory defects and aesthetic damage. In this study we focused on two genetic syndromes with macroglossia: Beckwith-Wiedemann Syndrome (BWS and Down Syndrome (DS: 7 patients were evaluated for logopedic treatment: 3 are affected by BWS, 2 are affected by DS. In addition, 2 patients with isolated atypical swallowing were included in the study to emphasize problems connected with atypical swallowing. All the patients underwent a global examination and a personalized logopedic therapy scheme was planned. With the exception of one of them who was lost to follow up and who did not continue with the exercises the speech therapist had recommended, all the children showed good response and compliance with remarkable improvements, thus proving the importance of an early, constant and intensive logopedic treatment.

    The origin of chemically peculiar stars remains enigmatic, especially regarding their frequency among their "normal" peers. In addition to magnetic fields and rotation, multiplicity may shed light on the question. We mention the main surveys of the three kinds performed so far of intermediate mass stars, either normal or chemically peculiar, magnetic or not: imaging, spectroscopic, and photometric. We also consider the mulitiplicity of red giant stars, since many of them are descendants of A-type stars, through Mermilliod's radial velocity monitoring of open cluster members. We briefly review the orbital properties of binary systems hosting chemically peculiar stars. Some specific objects of special interest are mentioned as deserving further study. Finally, we recall that some binary systems composed of A-type stars are progenitors of Type Ia supernovae, and evoke the potentialities of future surveys like Gaia.

    Full Text Available Study of 18 cases of post-operative CS wound infection due to Atypical Mycobacterium (M. chelonae were found in a single hospital over a six-month period. Though the contaminating source could not be identified, remedial control measures taken includes changing all the operative equipment, autoclave machine, air conditioners, exhaust fans of OT, linen and mattresses and solutions like betadine, savlon, spirit and also suture material replaced with new ones. Antibiotic protocols are changed and daily cleaning of OT with cetrimide solution and daily fumigation for one month. No further Atypical MB infective episode have occurred in the one and a half year since the study. Awareness of this ubiquitous opportunistic organism that is not easily eradicated from the hospital environment and strong suspicion of chronic post-operative wound infection, careful surveillance, detailed attention to disinfectant methods of medical devices and appropriate control measures are essential to prevent potential outbreaks.

    Spectropolarimetric observations of prominences have been obtained with the THEMIS telescope during four years of coordinated campaigns. Our aim is now to understand the conditions of the cool plasma and magnetism in `atypical' prominences, namely when the measured inclination of the magnetic field departs, to some extent, from the predominantly horizontal field found in `typical' prominences. What is the role of the magnetic field in these prominence types? Are plasma dynamics more important in these cases than the magnetic support? We focus our study on three types of `atypical' prominences (tornadoes, bubbles and jet-like prominence eruptions) that have all been observed by THEMIS in the He I D_3 line, from which the Stokes parameters can be derived. The magnetic field strength, inclination and azimuth in each pixel are obtained by using the Principal Component Analysis inversion method on a model of single scattering in the presence of the Hanle effect.

Lesions characterized on T2-weighted images by a well-defined rim of increased signal intensity and a concentric region of higher signal intensity were seen in 6 of 132 patients with MS. On T1-weighted images these lesions were evident as regions of low signal intensity, often with a rim of contrast enhancement or increased signal intensity. These appearances tended to be shown by new, evolving lesions. (orig.)

    Calcium intake shows a small impact on bone mineral density and fracture risk. Denosumab is a more potent inhibitor of bone resorption than zoledronate. Abaloparatide, PTHrP analog, increases bone mineral density and decreases fracture incidence. Teriparatide could be delivered via a transdermic device. Romosozumab and odanacatib improve calculated bone strength. Sequential or combined treatments with denosumab and teriparatide could be of interest, but not denosumab followed by teriparatide. Fibrous dysplasia, Paget disease and hypophosphatasia are updated, as well as atypical femoral fracture and osteonecrosis of the jaw. PMID:26946704

    Multiple factors determine handedness including genetics, prenatal stress and post-natal environmental conditions. Atypical handedness, whether manifest as increased sinistrality or decreased strength of lateral preference, has been noted in a wide variety of populations with neuropathology. Those with atypical sexual preferences, specifically paedophilia, also manifest reduced rates of right-handedness. This paper uses the largest sample of phallometrically assessed men to date to establish the pattern of atypical handedness in paedophilia. Specifically, whereas prior research has largely characterized participants dichotomously as right-handed or non-right-handed and/or used self-report of writing hand, this paper expands upon such reports by using the Edinburgh Handedness Inventory's laterality quotient. Participants' handedness and phallometrically assessed sexual preference were analyzed both as continuous and categorical variables, and the responses of those scoring in the range of ambiguous-handedness were evaluated to ascertain whether they were ambiguously handed or more accurately described as mixed-handed. Results indicated those producing scores in the range of ambiguous-handedness demonstrated response patterns consistent with ambiguous-handedness, rather than mixed-handedness. Paedophiles demonstrated high rates of non-right-handedness primarily manifested as sinistrality, whereas those who had a sexual preference for pubescent children evidenced increased ambiguous-handedness. Results support a view of ambiguous-handedness as less pathological than previously hypothesized, and of a neurodevelopmental origin of paraphilic sexual preferences. PMID:24666135

    Full Text Available Abstract Background To report atypical features on Spectral domain optical coherence tomography (SD-OCT in a case of non-familial pure adult nanophthalmos. Case presentation A 39 year old male hyperope was found to have biometric and fundus findings typical of nanophthalmos. The additional atypical features included serous pigment epithelial detachment (PED in right eye and a cuff of subretinal fluid with underlying yellow deposits along superotemporal arcade in the left eye. Fundus flourescein angiogram showed hyperfluorescence due to window defect, dye pooling due to serous PED in right eye and leak superior to disc in right eye and superotemporally in left eye. Cirrus-SD OCT horizontal line scan passing through the fovea showed extensive inner limiting membrane corrugations causing distorted foveal contour in both eyes. A large juxtafoveal serous PED and a small extrafoval PED were seen with folds in the retinal pigment epithelium (RPE-choriocapillary layer in the right eye. Conclusion Structural disruptions in the RPE-choriocapillary complex in the form of folds or juxtafoveal serous PED and RPE folds can be atypical features of nanophthalmic macula better discerned on high resolution OCT.

    Objective: To probe into the mechanism on TCM treatment of infectious atypical pneumonia (severe acute respiratory syndrome, SARS) and evaluate its feasibility and effectiveness. Method: Twelve TCM prescriptions of herbal drugs (orally or iv) were used to treat 16 cases of SARS without using glucocorticoids, anti-viral agents, immune-regulators or antibiotics (in case there was no definite bacterial infections). The symptoms, signs, chest roentgenograms and lab examinations were carefully monitored and recorded for evaluation of the effectiveness. Results: The average fever abatement time was 4.44±1.46days and the mean absorption time of gross pulmonary infiltration was 10.87±2.92 days. No exacerbation occurred during the treatment. Conclusion: TCM intervention could effectively control and alleviate the symptoms and prevent the disease from exacerbation.

  15. Atypical presentations of congenital cutaneous candidiasis- presenting a cohort of 8 cases

    Full Text Available Congenital cutaneous candidiasis is an extremely rare disorder that usually presents within the first 6 days of life. We report 8 neonates who presented with generalized skin eruptions within first 6 days of life, characterized by erythematous macules, papules, vesicles, bullae and pustules. Candida albicans was demonstrated on direct KOH smear, fungal culture and skin biopsy. The disease implies a congenital intrauterine infection and is different from neonatal candidiasis, which manifests as thrush or diaper dermatitis.Although congenital cutaneous candidiasis is a rare diagnosis and the predisposing factors like prematurity,candidial infection in the mother are not obvious, a high index of suspicion is required to diagnose the neonates with this condition and it is very evident that congenital cutaneous candidiasis has got a good prognosis. This article apart from revealing the atypical presentations of cutaneous congenital candidiasis, also emphasizes the need to screen all pregnant women for vaginal candidiasis .

    Acute Zika virus infection usually presents with a self-limiting triad of fever, rash and arthritis. There is limited information on severe or lethal cases. We report three cases of lethal acute Zika infection, confirmed with polymerase chain reaction, in adult patients with some co-morbidities. The patients showed rapid clinical deterioration with hemorrhagic and septic shock, and exaggerated acute and innate inflammatory responses with pronounced coagulopathy, and died soon after admission to the hospital. It remains unclear whether the fatal outcomes were due to acute Zika virus infection alone or to the combination with exacerbated underlying prior disease or co-infection. Nonetheless, the severity of these cases implies that increased awareness for atypical presentations of Zika virus infection, and careful clinical assessment of patients with symptoms of Zika, is warranted during current and future outbreaks.

    Full Text Available Renal squamous cell cancer is one of the rare primary urothelial tumors with only a handful of cases reported in literature. Because of high grade, advanced and late presentation, they herald a grave prognosis. They are frequently associated with calculus disease, smoking, phenacetin consumption and foci of squamous metaplasia due to chronic irritation. Nephroureterectomy is the treatment of choice for such tumors. We hereby present a case of 59 year old female who presented with squamous cell cancer of renal pelvis. The case presented here is different from what has already been reported in literature, as the patient had no antecedent risk factors for renal squamous cell carcinoma.-------------------------------------------------Cite this article as: Pahwa M, Pahwa AR, Girotra M, Chawla A.

    MR findings of early infectious spondylodiscitis are non-specific and may be confused with those of other conditions. Therefore, it is important to recognize early MR signs of conditions, such as inappreciable cortical changes in endplates, confusing marrow signal intensities of vertebral bodies, and inflammatory changes in paraspinal soft tissues, and subligamentous and epidural spaces. In addition, appreciation of direct inoculation, such as in iatrogenic spondylodiscitis may be important, because the proportion of patients who have undergone recent spine surgery or a spinal procedure is increasing. In this review, the authors focus on the MR findings of early spondylodiscitis, atypical findings of iatrogenic infection, and the differentiation between spondylodiscitis and other disease entities mimicking infection.
