    In this report we describe the case of an 18 year old female who presented with fever, shortness of breath, and chest pain. Chest X-ray revealed diffuse bilateral infiltrates and eosinophilia was reported from her broncholaveolar lavage (BAL) fluid. She started smoking 3 weeks prior to the onset of symptoms and based on her clinical presentation, BAL findings and dramatic improvement, acute eosinophilic pneumonia (AEP) was diagnosed.

    A case of eosinophilic pneumonia due to Nicolase (serrapeptase) after recovery from acute eosinophilic pneumonia is described. A 32-year-old woman was previously admitted to another hospital because of acute onset of dyspnea accompanied by cough and fever. Chest X-ray films revealed diffuse infiltration in both lungs two days after her symptoms occurred. Her bronchoalveolar lavage fluid showed 13% eosinophils and transbronchial lung biopsy specimen also showed many eosinophils infiltrating in the lesions of the bronchial submucosa and alveolar septa. No infectious causes or related drugs were found. Acute eosinophilic pneumonia was diagnosed, and her condition improved gradually without steroid treatment. Because she recovered clinically and radiologically, she was discharged from hospital. Half a month later she was treated with Nicolase because of pharyngitis. She was admitted to the hospital again because of dyspnea, cough and fever three days after commencing to take Nicolase. Chest X-ray films also revealed diffuse infiltration in both lungs with pleural effusion, and her bronchoalveolar lavage fluid showed 37% eosinophils. When the drug lymphocyte stimulation test was performed, it was positive for Nicolase. Therefore drug-induced eosinophilic pneumonia was diagnosed. This is a very rare case of Nicolase (serrapeptase)-induced eosinophilic pneumonia after recovering from acute eosinophilic pneumonia.

    Eosinophilic esophagitis is a worldwide chronic allergic disease of the esophagus. In the last decade, there is an epidemic of this entity in the western world. Mostly seen in children and young adults, patients present with dysphagia or food impaction in the emergency room. Characteristic endoscopic findings, esophageal eosinophilia and non-responsiveness to proton pump inhibitors help make the diagnosis. Avoidance of food allergens, administration of steroidal anti-inflammatory medications and dilation of the esophagus are the mainstays of treatment. Investigations are ongoing for mucosal healing and optimum maintenance treatment. PMID:27158535

    Adult-onset eosinophilic asthma is increasingly recognised as a severe and difficult-to-treat subtype of asthma. In clinical practice, early recognition of patients with this asthma subtype is important because it may have treatment implications. Therefore, physicians need to know the distinct characteristics of this asthma phenotype. The objective of the present study was to determine the characteristic profile of patients with adult-onset eosinophilic asthma. 130 patients with adult-onset (>18 years of age) asthma and high blood eosinophil counts (≥0.3×109 L−1) were compared with 361 adult-onset asthma patients with low (<0.3×109 L−1) blood eosinophils. Measurements included a series of clinical, functional and imaging parameters. Patients with high blood eosinophils were more often male, had less well controlled asthma and higher exacerbation rates, despite the use of higher doses of inhaled corticosteroids. They had higher levels of total IgE without more sensitisation to common inhaled allergens. In addition, these patients had worse lung function, and more often showed fixed airflow limitation, air trapping, nasal polyposis and abnormalities on sinus computed tomography scanning. Chronic rhinosinusitis, air trapping and male sex were three independent factors associated with blood eosinophilia (adjusted OR 3.8 (95% CI 1.7–8.1), 3.0 (95% CI 1.1–8.1) and 2.4 (95% CI 1.3–4.4), respectively). Patients with adult-onset asthma with elevated blood eosinophils exhibit a distinct profile, which can readily be recognised in clinical practice. PMID:27730197

    We report a case of Acute Eosinophilic Pneumonia (AEP) in a 29-year-old white woman with recent use of a'flea bomb' (containing pyrethroids) at home while remaining indoors, about 48 hours prior to presentation, and recent change in smoking habit (restarted 2 weeks prior after quitting for 10 years). She presented with two days of worsening fever, shortness of breath, productive cough, developed hypoxemic respiratory failure and ARDS. She required a PEEP of 20 and 100% FiO2 to maintain oxygenation. Bronchoalveolar lavage showed 36% Eosinophils. She was given IV steroids with dramatic clinical and radiological improvement. To the best of our knowledge, this is the second report associating AEP with pyrethroid exposure. PMID:27434983

    Eosinophilic granulomatosis with polyangiitis is a rare primary vasculitic disease characterized by hypereosinophilia, late onset asthma and extravascular eosinophil granulomas. We report a case presented initially with acute myocardial infarction which later only proceed with asthma, skin manifestations and peripheral neuropathy. Laboratory parameters showed hypereosinohpilia with negative perinuclear pattern of antineutrophil cytoplasmic autoantibodies (p-ANCA). Skin biopsy showed leucocytoclastic vasculitis with eosinophilic infiltration while coronary angiography was normal. The patient's symptoms improved with IV methylprednisolone, pulse cyclophosphamide and azathioprine.

    We report a case of a female patient who developed acute eosinophilic pneumonia (AEP) after recent onset of smoking and exposure to glyphosate-surfactant.The additional exposure associated with the recent start of smoking may have contributed to the development and/or severity of AEP.A clinical relapse after re-challenge four years later both with smoking and glyphosate-surfactant made the association highly likely.Respiratory distress is a factor of poor outcome and mortality after ingestion of glyphosate-surfactant.This case highlights the importance of a thorough exposure history e.g., possible occupational and environmental exposures together with drug-intake.Genotyping should be considered in cases of severe unexplained pulmonary damage.

    We report a sentinel case of acute eosinophilic pneumonia in a firefighter exposed to high concentrations of World Trade Center dust during the rescue effort from September 11 to 24. The firefighter presented with a Pa(O2) of 53 mm Hg and responded to oxygen and corticosteroids. Computed tomography scan showed patchy ground glass density, thickened bronchial walls, and bilateral pleural effusions. Bronchoalveolar lavage recovered 70% eosinophils, with only 1% eosinophils in peripheral blood. Eosinophils were not degranulated and increased levels of interleukin-5 were measured in bronchoalveolar lavage and serum. Mineralogic analysis counted 305 commercial asbestos fibers/10(6) macrophages including those with high aspect ratios, and significant quantities of fly ash and degraded fibrous glass. Acute eosinophilic pneumonia is a rare consequence of acute high dust exposure. World Trade Center dust consists of large particle-size silicates, but fly ash and asbestos fibers may be found in bronchoalveolar lavage cells.

  10. Clinical features of Eosinophilic esophagitis in children and adults.

    2015-10-01

    Eosinophilic esophagitis (EoE) may affect humans at any age with a predominance for Caucasian males. The clinical manifestation of EoE varies depending on the patient's age. Infants and young children may primarily present with unspecific symptoms such as feeding problems, vomiting and abdominal pain. In adolescents and adults, dysphagia and food impactation become the predominant symptoms. EoE should also be considered in cases of refractory heartburn in both children and adults. Concomitant allergic diseases such as asthma, rhinitis and eczema, as well as peripheral eosinophilia and elevated total serum IgE values are common in pediatric and adult EoE patients. EoE seems to be primarily a food antigen-driven disease, whereas in adults, aeroallergen sensitization may dominate. Endoscopic features of EoE include mucosal edema, furrows, exudates, corrugated rings, strictures, and the so-called crepe paper sign. There appears to be a shift from an inflammatory-predominant phenotype in young childhood towards a more fibrotic phenotype in adolescents and adults. Long-term follow studies suggest that EoE is a chronic and potentially progressive disease causing recurring dysphagia in the majority of cases. The prevalence of strictures significantly increases with the duration of untreated disease, stressing the importance of early diagnosis and consequent treatment of EoE. PMID:26552773

  11. Classification of eosinophilic gastrointestinal diseases.

    PubMed

    2008-01-01

    Diagnosis of eosinophilic gastrointestinal diseases is based on morphological evaluation with regard to localization and density of eosinophil infiltration of the mucosa and/or deeper parts of the oesophagus, stomach, and bowel in biopsy or resection specimens. As with eosinophils in any tissue, in the majority of diseases they are probably a sequel of acute inflammation and do not indicate any specific disease. Eosinophil morphology includes intact cells with bilobated nuclei and eosinophil granules in the cytoplasm and extracellular tissue following activation/degranulation. There is no fixed number of eosinophils that can be used as a cut-off criterion to define disease. Associated histopathological features observed in eosinophilic gastrointestinal disease depend on the site of manifestation and primary disease. Eosinophils are typically increased in allergy-associated colitis in adults and allergic proctocolitis in infants, eosinophilic gastroenteritis and eosinophilic oesophagitis. Their presence can also suggest a drug-induced eosinophilia or the presence of a parasitic infection. In general, eosinophils are increased in inflammatory bowel disease (IBD). They are seen in reflux oesophagitis, coeliac disease, and microscopic and infectious colitis. Eosinophils may be a feature of polyarteriitis nodosa and Churg-Strauss syndrome, and can accompany connective-tissue disease as well as malignant lymphomas and adenocarcinomas of gastrointestinal mucosa.

    Eosinophilic esophagitis (EoE) is a clinicopathologic condition of increasing recognition and prevalence. In 2007, a consensus recommendation provided clinical and histopathologic guidance for the diagnosis and treatment of EoE; however, only a minority of physicians use the 2007 guidelines, which require fulfillment of both histologic and clinical features. Since 2007, the number of EoE publications has doubled, providing new disease insight. Accordingly, a panel of 33 physicians with expertise in pediatric and adult allergy/immunology, gastroenterology, and pathology conducted a systematic review of the EoE literature (since September 2006) using electronic databases. Based on the literature review and expertise of the panel, information and recommendations were provided in each of the following areas of EoE: diagnostics, genetics, allergy testing, therapeutics, and disease complications. Because accumulating animal and human data have provided evidence that EoE appears to be an antigen-driven immunologic process that involves multiple pathogenic pathways, a new conceptual definition is proposed highlighting that EoE represents a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominant inflammation. The diagnostic guidelines continue to define EoE as an isolated chronic disorder of the esophagus diagnosed by the need of both clinical and pathologic features. Patients commonly have high rates of concurrent allergic diatheses, especially food sensitization, compared with the general population. Proved therapeutic options include chronic dietary elimination, topical corticosteroids, and esophageal dilation. Important additions since 2007 include genetic underpinnings that implicate EoE susceptibility caused by polymorphisms in the thymic stromal lymphopoietin protein gene and the description of a new potential disease phenotype, proton pump inhibitor

    To survey pediatric (PGI) and adult gastroenterologists (AGI) regarding their perceptions about the etiology, diagnosis, and management of eosinophilic esophagitis (EoE), and to assess whether differences in the clinical approach to EoE exist between these subspecialists. A 21-item survey related to EoE was emailed to PGI who subscribe to the PEDSGI Bulletin Board, and to two AGI per Electoral College vote in the US, randomly selected from each state. The survey was voluntary, and consent was assumed based on survey submission. The responses were submitted anonymously and results compiled in a secure Web site. A total of 249 physicians from across the globe responded to the survey, 68% of whom were PGI. The majority of respondents worked primarily in an academic institution or teaching hospital. Respondents revealed diagnosing an average of six cases (median 8, range 0-30) of EoE in the past 6 months. Ninety-two percent of AGI who see a patient with dysphagia and suspected EoE proceed to endoscopy with biopsies, compared to only 54% of PGI (P < 0.05); 38% of PGI would first perform an upper GI study. Both subspecialties agreed that biopsies of the proximal and distal esophagus are needed to make a definitive diagnosis of EoE. Fifty-eight percent PGI and 44% AGI defined EoE as an eosinophilic density of > or =20 per high power field (hpf) in esophageal biopsies. Seventy-seven percent of PGI but only 16% of AGI reported routine referral of patients for food allergy evaluation (P < 0.05). While 77% PGI and 91% of AGI would rely on a symptom-based follow-up, 27% PGI versus 9% AGI follow patients with biopsies according to a pre-determined schedule and another 38% repeat biopsies as needed, versus 15% AGI. This survey exposes a few inconsistencies among gastroenterologists in the diagnosis, management, and follow-up of patients with EoE. The currently available practice guidelines for the diagnosis and management of EoE are largely based on retrospective studies and

    Esophageal dilation is an effective therapy for dysphagia in patients with stenosing eosinophilic esophagitis (EoE). Historically, there have been significant concerns of increased perforation rates when dilating EoE patients. More recent studies suggest that improved techniques and increased awareness have decreased complication rates. The aim of this study was to explore the safety of dilation in our population of EoE patients. A retrospective review of all adult EoE patients enrolled in a registry from 2006 to 2010 was performed. All patients who underwent esophageal dilation during this time period were identified and included in the analysis. Our hospital inpatient/outpatient medical records, radiology reports, and endoscopy reports were searched for evidence of any complication following dilation. Perforation, hemorrhage, and hospitalization were identified as a major complication, and chest pain was considered a minor complication. One hundred and ninety-six patients (41 years [12]; mean age [standard deviation], 80% white, 85% male) were identified. In this cohort, 54 patients (28%) underwent 66 total dilations (seven patients underwent two dilations, one patient underwent three dilations, and one patient underwent four dilations). Three dilation techniques were used (Maloney [24], Savary [29] and through-the-scope [13]). There were no major complications encountered. Chest pain was noted in two patients (4%). There were no endoscopic features (rings, furrows, plaques) associated with any complication. Type of dilator, size of dilator, number of prior dilations, and age of patient were also not associated with complications. Endoscopic dilation using a variety of dilators can be safely performed with minimal complications in patients with EoE.

    A total of 3 cases of acute lead poisoning in calves was confirmed by atomic absorption spectrophotometric analysis of biological samples, presence of an acute lead exposure source, clinical signs of impaired vision in one case and eosinophilic meningoencephalitis in another case. One of two other calves which died approximately 2 months earlier had nervous signs and it is likely that they also had lead poisoning. Dams of two of the cases did not have elevated lead levels. Municipal sewage sludge had been applied to most fields on the farm during the preceding 5 year period. There had been approximately a doubling of the lead content in the soil; however, the foodstuffs produced on the farm had low lead concentrations. The extremely high lead levels in the abomasal contents and feces of calves eliminated sludge as the source of the lead in this acute poisoning episode. The contents of oil filters, accessible to calves but not to adult cattle, had lead levels as high as 26,922 micrograms/g and was the most likely lead source responsible for this lead intoxication. It appears that the manifestation of eosinophilic meningoencephalitis in lead poisoning cases may occur in young calves as well as in cows and in acute as well as in chronic intoxications.

    Acute mucocutaneous methotrexate toxicity is not classically associated with prominent tissue eosinophilia. We present a case of acute methotrexate toxicity associated with pancytopenia and mucocutaneous erosion with interface dermatitis and numerous eosinophils. A 79-year-old male, with a history of psoriasis vulgaris on methotrexate therapy, presented with blisters of the oral mucosa, groin, sacrum, and extremities after daily consumption of methotrexate. Examination revealed blisters and erosions localized to psoriatic plaques, the perineum, and the oral mucosa. Laboratory evaluation demonstrated pancytopenia, megaloblastic anemia, and elevated liver function tests. A skin biopsy of an eroded plaque revealed psoriasiform epidermal hyperplasia with epidermal erosion, parakeratosis, and loss of the granular cell layer. There was an underlying band-like lymphoid infiltrate with interface dermatitis, dyskeratotic keratinocytes, and numerous eosinophils. Direct immunofluorescence studies were negative for the deposition of immunoreactants. Methotrexate was held, and the patient received leucovorin resulting in improvement of blood counts and cutaneous lesions. The histopathologic changes associated with acute mucocutaneous toxicity have been described as pauci-inflammatory erosions associated with dyskeratotic keratinocytes to interface dermatitis with necrotic keratinocytes and occasionally associated eosinophils. Although these changes are most often superimposed on psoriatic plaques, they have been reported to occur on normal skin. Therefore, the differential diagnosis may include lichen planus, a lichenoid drug eruption, or a fixed drug eruption, and given the presence of mucosal ulceration, incipient pemphigus vulgaris or paraneoplastic pemphigus vulgaris. This case illustrates that acute mucocutaneous methotrexate toxicity may be associated with both interface dermatitis and numerous eosinophils. PMID:23221488

Pulmonary infections due specifically to Ascaris, hookworms, Strongyloides, Paragonimus, filariasis, and Toxocara are considered in detail. The discussion then moves to noninfectious causes of eosinophilic pulmonary infiltration, including allergic sensitization to Aspergillus, acute and chronic eosinophilic pneumonias, Churg-Strauss syndrome, hypereosinophilic syndromes, and pulmonary eosinophilia due to exposure to specific medications or toxins.

  1. Quantitative analysis of eosinophils in acute graft-versus-host disease compared with drug hypersensitivity reactions.

    2010-02-01

    Acute graft-versus-host disease (aGVHD), if not detected and treated early, is a common cause of morbidity and mortality. Drug hypersensitivity reactions (DHRs), the most frequent clinical and histopathological mimickers of early aGVHD, are often still distinguished from aGVHD by the presence of eosinophils within the inflammatory infiltrate on skin biopsy. Distinguishing these entities is important because the delay of appropriate treatment of aGVHD may lead to advanced stages of the disease process with a poor prognosis. To determine whether the existence or amount of eosinophilic infiltrate could be used to differentiate these entities, we employed a quantitative method of analyzing eosinophils in skin biopsies of rashes from patients with aGVHD and DHR. Eosinophils were counted in 50 high-power fields (HPFs) in skin biopsies of patients with clinical grade >or=2 aGVHD (+aGVHD), with clinical grade <2 aGVHD (-aGVHD), and those with clinical DHR (+DHR). The average number of eosinophils per 10 HPFs (ave. eos/10 HPFs) increased throughout each group. The ave. eos/10 HPFs in +DHR was significantly different from both aGVHD groups (P < 0.001). The specificity to completely rule out aGVHD did not reach 100% until 16.0 ave. eos/10 HPFs was observed. There is a significant difference between the numbers of eosinophils found in differentiating DHR from aGVHD, but a very high number (>16.0 ave. eos/10 HPFs) is necessary to rule out aGVHD completely. Therefore, a quantitative analysis of eosinophils in all biopsies to rule out aGVHD would be of limited value and should only be considered in those biopsies with significant eosinophilia.

    Eosinophilic gastroenteritis (EG) is characterized by eosinophilic infiltration of the bowel wall and variable gastrointestinal manifestations. Clinicians should have a high index of suspicion for EG when faced with gastrointestinal symptoms and peripheral eosinophilia to avoid incorrect diagnosis and inappropriate treatments. A 24-year-old woman was admitted to our hospital complaining of acute right lower quadrant abdominal pain and a laparoscopic appendectomy performed for a presumed diagnosis of an acute appendicitis. However, the procedure revealed bowel edema and a moderate amount of ascites without evidence of a suppurative appendicitis. Postoperatively, she showed persistent and progressive eosinophilia, exudative eosinophilic ascites, eosinophilic infiltration of the resected appendix wall, and eosinophilic infiltration of gastroduodenal mucosa. A punch biopsy of the abdominal skin also revealed inflammation with marked eosinophilic infiltration of the skin. She recovered after the treatment with a low dose of steroid for the EG with eosinophilic dermatitis. EG with eosinophilic dermatitis has not been reported yet and is considered fortuitous in this case. PMID:20046530

    Introduction An estimated 4000 million cases of diarrhoea occurred worldwide in 1996, resulting in 2.5 million deaths. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute diarrhoea in adults living in resource-rich countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries traveling to resource-poor countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults living in resource-poor countries? What are the effects of treatments for acute severe diarrhoea in adults living in resource-poor countries? We searched: Medline, Embase, The Cochrane Library and other important databases up to January 2007 (BMJ Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review).

    Introduction An estimated 4.6 billion cases of diarrhoea occurred worldwide in 2004, resulting in 2.2 million deaths. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for acute diarrhoea in adults living in resource-rich countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults from resource-rich countries travelling to resource-poor countries? What are the effects of treatments for acute mild-to-moderate diarrhoea in adults living in resource-poor countries? What are the effects of treatments for acute severe diarrhoea in adults living in resource-poor countries? We searched: Medline, Embase, The Cochrane Library, and other important databases up to January 2010 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 72 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotics, antimotility agents, antisecretory agents, bismuth subsalicylate, diet, intravenous rehydration, nasogastric tube rehydration, oral rehydration solutions (amino acid oral rehydration solution, bicarbonate oral rehydration solution, reduced osmolarity oral rehydration solution, rice-based oral rehydration solution, standard oral rehydration solution), vitamin A supplementation, and zinc supplementation.

    While increased numbers of eosinophils may be detected in patients with graft-versus-host disease (GVHD) following hematopoietic stem cell transplantation, it is not known if eosinophils play a role in GVHD. The aims of this study were to determine: whether eosinophils are activated during GVHD; whether the patterns of activation are similar in acute and chronic GVHD; and the ways in which systemic corticosteroids affect eosinophils. Transplanted patients (n = 35) were investigated for eosinophil numbers and the expression levels of 16 eosinophilic cell surface markers using flow cytometry; all the eosinophil data were analyzed by the multivariate method OPLS-DA. Different patterns of molecule expression were observed on the eosinophils from patients with acute, chronic, and no GVHD, respectively. The molecules that provided the best discrimination between acute and chronic GVHD were: the activation marker CD9; adhesion molecules CD11c and CD18; chemokine receptor CCR3; and prostaglandin receptor CRTH2. Patients with acute or chronic GVHD who received systemic corticosteroid treatment showed down-regulation of the cell surface markers on their eosinophils, whereas corticosteroid treatment had no effect on the eosinophil phenotype in the patients without GVHD. In summary, eosinophils are activated in GVHD, display different activation profiles in acute and chronic GVHD, and are highly responsive to systemic corticosteroids. PMID:25400930

  7. Eosinophils contribute to killing of adult Onchocerca ochengi within onchocercomata following elimination of Wolbachia.

    Many filarial nematodes, including Onchocerca volvulus (the cause of human 'River Blindness'), have a mutually dependent relationship with Wolbachia bacteria. There has been much interest in Wolbachia as a chemotherapeutic target, since there are no macrofilaricidal drugs (i.e., lethal to adult worms) of low toxicity. Using the bovine parasite O. ochengi, we previously demonstrated that combined intensive and intermittent (COM) oxytetracycline treatment induces a sustained depletion of Wolbachia and is macrofilaricidal, whereas a short intensive regimen (SIR) is non-macrofilaricidal. To understand how targeting Wolbachia with oxytetracycline can lead to worm death, O. ochengi nodules (onchocercomata) were sequentially excised from cattle administered COM or SIR therapy, and cell infiltrates were microscopically quantified. Pre-treatment, worms were surrounded by neutrophils, with eosinophils rare or absent. At 8-12weeks after either regimen, eosinophils increased around worms and were observed degranulating on the cuticle. However, with the SIR treatment, neutrophils returned to predominance by 48weeks, while in the COM group, eosinophilia persisted. These observations suggest that accumulation of degranulating eosinophils over a prolonged period is a cause rather than an effect of parasite death, and the macrofilaricidal mechanism of antibiotics may relate to facilitation of eosinophil infiltration around worms by ablation of Wolbachia-mediated neutrophilia.

    Acute eosinophilic pneumonia (AEP) can be a challenging diagnosis and is often initially misdiagnosed as one of the more common pneumonia syndromes such as acute respiratory distress syndrome. Early bronchoalveolar lavage (BAL) is critical in distinguishing the diagnosis to initiate proper management. The etiology of AEP is unknown, though many drugs have been implicated, including minocycline. Minocycline is commonly used for pneumonia, acute bronchitis, urinary tract infections, and acne and is likely the cause of AEP in our patient. There are 26 case reports of minocycline-induced AEP. In most cases, outcomes were favorable and symptoms rapidly resolved upon discontinuation of minocycline, with 11 cases employing steroids, one case twelve hours of CPAP and another 5 days of intubation. None resulted in mortality. Although it is difficult to evaluate without further studies, steroids should be recommended for minocycline-induced AEP, especially for those with severe or persistent symptoms. PMID:26236618

    Background & Aims Eosinophilic esophagitis (EoE) is an immune-mediated disorder. Food elimination is an established treatment for children, but data in adults are limited. We aimed to determine the response of adults with EoE to dietary therapy. Methods This was a retrospective cohort study using the University of North Carolina EoE database from 2006–2012. Subjects were ≥18 years, had EoE by consensus guidelines, and had undergone dietary therapy either with targeted or six-food elimination (SFED). Outcomes were symptomatic, endoscopic, and histologic improvement. Demographic, endoscopic, symptomatic, and laboratory predictors of response to dietary therapy were assessed. Results Of 31 adults who underwent dietary therapy (mean age 36 years; 48% male; 90% white; mean baseline eosinophil count 78 eos/hpf), 22 had targeted and 9 had SFED. Symptoms improved in 71% (68% in targeted, 78% in SFED) and endoscopic appearance improved in 54% (53% in targeted, 56% in SFED). After dietary therapy, the mean eosinophil count decreased to 43 eos/hpf (p=0.009). Eleven subjects (39%) responded with <15 eos/hpf (32% in targeted and 56% in SFED; p=0.41). No clinical, endoscopic, or histologic factors predicted response to dietary therapy. Of the 11 responders, 9 underwent food reintroduction to identify trigger(s), and 4 (44%) reacted to dairy, 4 (44%) to eggs, 2 (22%) to wheat, 1 (11%) to shellfish, 1 (11%) to legumes, and 1 (11%) to nuts. Conclusions Dietary elimination is a successful treatment modality for adults with EoE. Further research should emphasize which factors can predict effective dietary therapy. PMID:24440337

    2012-11-01

    Eosinophilic esophagitis (EoE) is recognized as a common, allergy-associated cause of chronic esophageal symptoms affecting both children and adults. Research has begun to shed light on its epidemiology with consistent results from various geographical areas. Differences in clinical presentation, endoscopic aspects and response to treatment have all been reported for patients of different ages, and the question as to whether adult and pediatric EoE are manifestations of a single entity or in fact two distinct disorders has been posed. The most relevant differences between pediatric and adult EoE come from evolutionary changes in the consequences of the disease, including fibrous remodeling, and the ability to express symptoms. However, most studies support a common pathogenesis and similar histopathological features for adult and pediatric patients, being the same diagnostic criteria applied to them. This article comprehensively reviews the most recently published information and addresses important questions about the natural history of EoE.

    Anti-PD-1 inhibitors have significant activity in metastatic melanoma. Responses often occur early and may be sustained. The optimal duration of treatment with these agents is unknown. Here, we report the case of a 51-year-old woman treated with pembrolizumab, as part of the Keynote-001 trial, as first-line treatment for metastatic disease. She experienced a complete response after 13.8 months of treatment with no adverse events. One month after the last drug infusion and 18 months from starting treatment, the patient presented with eosinophilic fasciitis. She then developed acute confusion and weakness, thought to be due to intracranial vasculitis. High-dose steroids were initiated with resolution of the fasciitis. Aspirin was commenced for presumed vasculitis with resolution of the neurologic symptoms. To our knowledge, there are no previous reports of eosinophilic fasciitis or cerebral vasculitis due to anti-PD-1 agents. This case demonstrates that toxicity may occur in association with pembrolizumab treatment after a prolonged period of treatment without toxicity. Future trials should explore the optimal duration of treatment with pembrolizumab.

    Eosinophilic esophagitis (EoE) is a chronic immune/antigen-mediated esophageal disease characterized by esophageal dysfunction and esophageal mucosal eosinophilia. Diet therapy is effective in the treatment of EoE in both children and adults. The role of food allergens is well established in the pathogenesis and treatment of eosinophilic esophagitis. Empiric elimination with a six-food elimination diet (avoiding milk, wheat, egg, soy, peanuts/tree nuts, and fish/shellfish) demonstrates remission in over 70% of adults with this disease. Dietary therapy in adult EoE is becoming more accepted by both patients and clinicians. Dietary therapy can be effectively implemented in clinical practice with appropriate dietary education, patient resources, and close communication with physician and clinical staff. The ability to identify specific food triggers to help tailor dietary therapy for long-term management allows for a return to consumption of most table foods. Furthermore, the diet approach avoids the need for chronic topical corticosteroid use and possible long-term side effects of these medications. The decision to proceed with dietary therapy should be decided by patient preference and available resources. A collaborative and multidisciplinary approach including gastroenterologists, allergists, nurses, and dietitians is essential in the success of this approach.

    2011-01-01

    Introduction About 10% of adults have suffered an attack of asthma, and up to 5% of these have severe disease that responds poorly to treatment. Patients with severe disease have an increased risk of death, but patients with mild to moderate disease are also at risk of exacerbations. Most guidelines about the management of asthma follow stepwise protocols. This review does not endorse or follow any particular protocol, but presents the evidence about specific interventions. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 100 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: beta2 agonists (plus ipratropium bromide, pressured metered-dose inhalers, short-acting continuous nebulised, short-acting intermittent nebulised, short-acting iv, and inhaled formoterol); corticosteroids (inhaled); corticosteroids (single oral, combined inhaled, and short courses); education about acute asthma; generalist care; helium–oxygen mixture (heliox); magnesium sulphate (iv and adding isotonic nebulised magnesium to inhaled beta2 agonists); mechanical ventilation; oxygen supplementation (controlled 28% oxygen and controlled 100% oxygen); and specialist care.

    Background. The relation of esophageal food bolus impaction (FBI) to eosinophilic esophagitis (EoE) and lymphocytic esophagitis (LyE) is unclear. The aim of this study was to determine the prevalence of EoE and LyE among adults with FBI. Methods. In this retrospective study we analyzed data from all patients referred for gastroscopy during the past 5 years, because of a present or recent episode of FBI. Results. We found 238 patients with FBI (median age 51 (17-96), 71% males). Endoscopic therapy was required in 143 patients. Esophageal biopsies were obtained in 185 (78%) patients. All biopsies were assessed for numbers of eosinophils and lymphocytes. EoE was found in 18% of patients who underwent biopsy. We found 41 patients (22%) who fulfilled the criteria for both EoE and LyE (EoE/LyE). LyE was found in the 9% of patients with FBI. EoE together with EoE/LyE was the leading cause of FBI in patients ≤50 years (64%). GERD was the leading cause of FBI among patients older than 50 years (42%). Conclusions. Our study showed that EoE was the leading cause of FBI in particular among young adults. Our study highlights the need for esophageal biopsies in any patient with FBI.

    2009-01-01

    Eosinophilic esophagitis is increasingly recognized in adults. The diagnosis is based on the presence of both typical symptoms and pathologic findings on esophageal biopsy. Patients usually present with dysphagia, food impaction and/or reflux-like symptoms, and biopsy of the esophagus shows more than 15 eosinophils per high-power field. In addition, it is essential to exclude the presence of known causes of tissue eosinophilia such as gastroesophageal reflux disease, infections, malignancy, collagen vascular diseases, hypersensitivity, and inflammatory bowel disease. There are no standardized protocols for the therapy of eosinophilic esophagitis. A variety of therapeutic approaches including acid suppression, dietary modifications, topical corticosteroids and endoscopic dilation can be used alone or in combination. PMID:19115464

    We report a case of a 49-year-old male patient with abdominal distension and diffuse stomach cramps associated with peripheral eosinophilia. Treatment for eosinophilic parasitosis was not effective. After a few weeks, the patient developed acute obstructive abdomen with ascites, which was atypically improved with the use of antispasmodics and analgesics. Upper digestive endoscopy, colonoscopy and histopathologic examination of the gastric and intestinal mucosa did not show any significant changes. Video laparoscopic biopsy of the mesenteric lymph node and peritoneum revealed a nonspecific chronic inflammatory process with intense diffuse tissue eosinophilia. Complementary tests revealed right-sided pleural effusion and increased serum immunoglobulin E levels, with altered D-xylose absorption test results. The patient was treated with a hypoallergenic diet and an oral corticosteroid; the symptoms resolved and the laboratory test results improved. Eosinophilic gastroenteritis is a rare inflammatory disease characterized by eosinophilic infiltration in the wall of the gastrointestinal tract. The clinical presentation varies according to the affected site and the depth and extent of digestive tract involvement. This case report, which presents the rare simultaneous involvement of the mucosal, muscular and serosal layers, aims to describe and discuss the clinical and therapeutic aspects of eosinophilic gastroenteritis as well as its progression.

    The author presents the clinical history of 14 patients, from 21 to 48 years of age, 10 men and 4 women, with a final diagnosis of acute epiglottitis who were hospitalized at Gorgas Army Hospital or at the San Fernando Clinic. All the patients had pharyngitis and dysphagia, a few with nasal voice, stridor and difficulty breathing, as the chief complaint. All the patients were initially intubated orally for diagnostic purposes and immediately after nasotracheal intubation was done until the patient improved in 2 or 3 days (one patient remained intubated for 5 days). All patients were kept in the Intensive Care Unit and were treated with Ampicillin and Chloramphenicol IV and lately with a second generation cephalosporin (Cefamandole). The patients allergic to Penicillin were treated with Clindamycin and Chloramphenicol. Corticosteroids were not used in any of the patients. There were no sequelae and none of the patients expired.

  7. A combination of predispositions and exposures as responsible for acute eosinophilic pneumonia

    2014-01-01

    Background Acute eosinophilic pneumonia (AEP) is a rare febrile illness which is characterized by respiratory failure and often requires mechanical ventilation. The causes and sequence of events of this disease at a biochemical and histological level remain largely unknown. In this article we report the exceptional case, possibly unique, of a patient who developed AEP and three pneumothoraces within less than one month during her hospitalization. Case presentation A 39-year-old German woman was admitted to our hospital for a laparoscopy-assisted vaginal hysterectomy under general anaesthesia. The surgical intervention was followed by peritonitis in the early postoperative course. Following anaesthesia induction with propofol/midazolam and during the prolonged therapy with several broad-spectrum antibiotics, she developed AEP and three spontaneous (one left-sided and two right-sided) pneumothoraces, the latter ones observed in quick succession. Symptoms, laboratory markers, and chest radiology significantly improved after a one-day treatment with methylprednisolone. Conclusions On the whole, these pathological occurrences, together with similar cases reported in literature, can support the conclusion of possible predisposing genetic factors at the lung tissue level of AEP patients, a view that might shed new light on the pathogenesis of this disease. To provide a coherent pattern that explains the reported evidence for AEP and pneumothoraces, independently from the causative stimulus, the supposed molecular mutations could be localized in the connective tissue rather than in the epithelial cells. In order to interpret clinical and laboratory evidence, as well as to support the main conclusions, the important part of scientific research here presented can also assist physicians in making more informed decisions for the treatment of patients with pulmonary infiltrates.

    Cocaine is a well known trigger of acute coronary syndromes. Over the last 10 years levamisole, a veterinary anthelminthic drug has been increasingly used as an adulterant of cocaine. Levamisole was used to treat pediatric nephritic syndrome and rheumatoid arthritis before being withdrawn from the market due to its significant toxicity, i.e. hematological complications and vasculitis. The major complications of levamisole-adultered cocaine reported up to now are hematological and dermatological. The case reported here is of a 25 year old man with a history of cocaine abuse who died at home after complaining of retrosternal pain. Postmortem CT-angiography, autopsy, and chemical and toxicological analyses were performed. An eroded coronary artery plaque was found at the proximal segment of the left anterior descending coronary artery. Two myocardial infarct scars were present in the left ventricle. Microscopic examination of the coronary artery revealed infiltration of eosinophils into the adventitia and intima. Toxicological examination confirmed the presence of cocaine and its metabolites in the peripheral blood, and of levamisole in the urine and pericardial fluid. Eosinophilic inflammatory coronary artery pathologies have been clinically linked to coronary dissection, hypersensitivity coronary syndrome and vasospastic allergic angina. The coronary pathology in the presented case could be a complication of levamisole-adultered cocaine use, in which an allergic or immune-mediated mechanism might play a role. The rise in cocaine addiction worldwide and the increase of levamisole adulterated cocaine highlights the importance of updating our knowledge of the effects of adultered cocaine abuse.

    There are many options for acute migraine attack treatment, but none is ideal for all patients. This study aims to review current medical office-based acute migraine therapy in adults and provides readers with an organized approach to this important facet of migraine treatment. A general literature review includes a review of several recent published guidelines. Acetaminophen, 4 nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, acetylsalicylic acid [ASA], naproxen sodium, and diclofenac potassium), and 7 triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan) have good evidence for efficacy and form the core of acute migraine treatment. NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics (acetaminophen, ASA, and caffeine), and several anti-emetics (metoclopramide, domperidone, and prochlorperazine) are additional evidence-based options. Opioid containing combination analgesics may be helpful in specific patients, but should not be used routinely. Clinical features to be considered when choosing an acute migraine medication include usual headache intensity, usual rapidity of pain intensity increase, nausea, vomiting, degree of disability, patient response to previously used medications, history of headache recurrence with previous attacks, and the presence of contraindications to specific acute medications. Available acute medications can be organized into 4 treatment strategies, including a strategy for attacks of mild to moderate severity (strategy one: acetaminophen and/or NSAIDs), a triptan strategy for patients with severe attacks and for attacks not responding to strategy one, a refractory attack strategy, and a strategy for patients with contraindications to vasoconstricting drugs. Acute treatment of migraine attacks during pregnancy, lactation, and for patients with chronic migraine is also discussed. In chronic migraine, it is particularly important that medication

    Mucosal mast cells (MMC) play a crucial role in the expulsion of Strongyloides ratti adults from the small intestine of mice. We reported the large intestinal parasitism of S. ratti in rats, and there has been no report on MMC in the large intestine of the natural host. We studied kinetics of MMC, together with eosinophils, in the upper and lower small intestines, caecum and colon of infected rats. Two distinct phases of mastocytosis were revealed: one in the upper small intestine triggered by stimulation of 'ordinary' adults, and the other in the colon stimulated by 'immune-resistant' adults that started parasitizing the colon around 19 days post-infection. In all 4 intestinal sites, the MMC peaks were observed 5-7 days after the number of adult worms became the maximum and the height of MMC peaks appeared to be dependent on the number of parasitic adults, suggesting an important role played by worms themselves in the MMC buildup.

    Context: Eosinophilic myocarditis is a rare cause of myocarditis. It is manifested histopathologically by diffuse or focal myocardial inflammation with eosinophilic infiltration, often in association with peripheral blood eosinophilia. Patients infected with Human Immunodeficiency Virus (HIV), especially those with lower CD4 counts, can occasionally have hyperimmunoglobulinemia E (Hyper IgE) and eosinophilia. Case Report: We report a case of a 29-year-old patient with Acquired Immunodeficiency Syndrome (AIDS) who had a persistent elevation of eosinophil counts and elevated IgE levels for a year prior to admission. He was presented to our emergency department with chest pain and laboratory tests revealed peripheral blood eosinophilia and elevated troponins. Coronary angiogram showed nonobstructive coronary artery disease. He then underwent cardiac magnetic resonance imaging which was consistent with an infiltrative myocarditis. After being put on steroid therapy, his peripheral eosinophilia resolved and his cardiac symptoms improved. Conclusion: Our case highlights that eosinophilia and Hyper IgE in HIV patients has the potential to contribute to end-organ damage. PMID:25077083

    Eosinophilic esophagitis (EoE) is a clinico-pathological entity characterised by symptoms of esophageal dysfunction and eosinophilia on esophageal mucosal biopsies in the absence of other causes of esophageal eosinophilia. It is a chronic inflammatory condition of esophagus often characterized by refractory reflux symptoms in children and dysphagia in adults. It occurs as a result of Th2 inflammatory response to environmental triggers (food antigens) in genetically predisposed individuals. The diagnostic criteria include symptoms of esophageal dysfunction, esophageal eosinophilia (> 15/hpf), and a PPI trial (persistent eosinophilia after 8 weeks of PPI). Mainstay of treatment at present is topical steroids and dietary therapy. Maintenance treatment should be considered to prevent long term complications. PMID:27522734

    Eosinophilic esophagitis (EE) is an atopic condition of the esophagus that has become increasingly recognized over the last decade. It is associated with a variety of esophageal symptoms such as dysphagia, food impaction and chest pain. Diagnosis of the disorder is dependent on the patient’s clinical presentation and histological findings on esophageal mucosal biopsies. Patients with eosinophilic esophagitis should be referred to an allergist for optimal management since studies suggest a link between allergies and EE. Management includes modifications of diet, medication therapy and mechanical dilation of the esophagus. This brief report provides an overview of the epidemiology, pathophysiology, diagnosis, treatment and a case from our encounter with a patient with EE.

    2013-01-01

    Eosinophilic meningitis is defined by the presence of at least 10% eosinophils in the total cerebrospinal fluid (CSF) leukocyte count. Although there are several possible causes of eosinophils in the CSF, parasitic infection is the main cause. The three common parasites causing eosinophilic meningitis include Angiostrongylus cantonensis, Gnathostoma spinigerum, and Taenia solium. Even though these parasites are endemic in tropical countries, they are now spreading globally due to extensive traveling, and physicians worldwide should pay more attention to this condition. This chapter will review risk factors, clinical manifestations, and treatment of these three parasites.

    PubMed

    Carreon, Chrystalle Katte; Esposito, Michael J

    2014-07-01

    Eosinophilic coronary monoarteritis is an unfamiliar cause of acute myocardial ischemia. Most commonly, it presents as a left-sided chest pain or sudden death in middle-aged women with no traditional risk factors for coronary artery disease. Because the abrupt onset leaves almost no time for intervention, the symptoms readily lead to death, and most cases are diagnosed at necropsy. Dissection of the coronary artery wall with resultant occlusion of the lumen, which commonly affects the left anterior descending artery, is a consistent gross finding. An inflammatory infiltrate, which is predominantly composed of eosinophils in the tunica adventitia and tunica media and is often accompanied by a hematoma in between these 2 layers, is observed histologically. The etiology remains unclear, but an increase in the activity of eosinophils because of hormonal interactions during pregnancy has been suggested. Interplay of hormones is thought to culminate in the release of histolytic agents by the eosinophils, which initiate the dissection process. Currently, there is no specific treatment for eosinophilic coronary monoarteritis, but cyclophosphamide and prednisone have shown positive results in the treatment of spontaneous coronary artery dissection with unspecified periadventitial inflammation. Percutaneous coronary procedures have also resulted in favorable outcomes in a subset of patients. Because of the high, sudden death rate in eosinophilic coronary monoarteritis, deciphering the underlying pathophysiology of this almost invariably fatal disease remains both a challenge and a key to developing screening methods that will allow timely detection and thus treatment.

    Eosinophilic esophagitis (EoE) prevalence fluctuates according to the population studied and varies from 0.4% in an open population to 6.5% in subjects with esophageal symptoms. Even though this entity has been described in North American and European populations, it is still considered an 'unusual' condition in Latin America. The study aimed to determine EoE prevalence in patients undergoing elective endoscopy in a tertiary referral center in southeastern Mexico. Consecutive patients were evaluated that had been referred to the Medical and Biological Research Institute, Veracruz, Mexico, for upper endoscopy due to gastrointestinal symptoms. Demographic variables and symptoms were analyzed in all the cases. Eight mucosal biopsies of the esophagus (four proximal and four distal) were obtained and were reviewed by a blinded pathologist. Histological diagnosis was established when the mean eosinophil count at a large magnification was ≥15. A total of 235 subjects (137 women, 51.16 years) were evaluated, and EoE prevalence was 1.7% (4/235 95% confidence interval 0.2-3.6%). In all four cases, pH test were normal. Among patients with histological diagnosis of EoE, a greater number of patients with a past history of asthma (50% vs. 19.3%, P = 0.04) and a tendency for a greater frequency of dysphagia (50% vs. 25%, P = 0.10). There were no differences in the endoscopic findings (rings, grooves, plaques, or stricture) when compared with the patients presenting with erosive esophagitis. EoE prevalence among patients undergoing upper endoscopy from southeastern Mexico was 1.7%, which can be regarded as intermediate to low.

    Eosinophilic esophagitis (EoE) has been associated with an increased risk of esophageal mucosal tears induced by vomiting to dislodge impacted food or following endoscopic procedures. However, Boerhaave's syndrome or transmural perforation of the organ resulting from vomiting induced to dislodge impacted food has rarely been reported. In this article, we present two male adult patients with long-term esophageal symptoms who suffered from Boerhaave's syndrome after the impaction of food in the esophagus. Both patients required surgical management because of clinical and radiological signs of perforation. This rare complication of EoE has been documented in 11 other reports, predominantly affecting young men in whom EoE had not been previously diagnosed, despite the majority having esophageal symptoms and a history of atopy. There are only two published cases of esophageal perforation that presented in children, which were managed conservatively. Our two patients and 4 out of the 11 described in literature required surgery because of esophageal perforation. Our two cases involved closure of the perforation, while in three published reports, perforation resulted in a partial or complete esophagectomy. No cases have been published on Boerhaave's syndrome caused by EoE that ended in fatalities. It is important to note that esophageal perforation caused by vomiting is a potentially severe complication of EoE that is being increasingly described in literature. Therefore, patients with non-traumatic Boerhaave's syndrome should be assessed for EoE, especially if they are young men who have a prior history of dysphagia and allergic manifestations.

    The aim of the present work was to evaluate the number of apoptotic eosinophils in the livers of sheep experimentally infected with Fasciola hepatica during the migratory and biliary stages of infection. Four groups (n=5) of sheep were used; groups 1-3 were orally infected with 200 metacercariae (mc) and sacrificed at 8 and 28 days post-infection (dpi), and 17 weeks post-infection (wpi), respectively. Group 4 was used as an uninfected control. Apoptosis was detected using immunohistochemistry with a polyclonal antibody against anti-active caspase-3, and transmission electron microscopy (TEM). Eosinophils were identified using the Hansel stain in serial sections for caspase-3, and by ultrastructural features using TEM. At 8 and 28 dpi, numerous caspase-3(+) eosinophils were mainly found at the periphery of acute hepatic necrotic foci. The percentage of caspase -3(+) apoptotic eosinophils in the periphery of necrotic foci was high (46.1-53.9) at 8 and 28 dpi, respectively, and decreased in granulomas found at 28 dpi (6%). Transmission electron microscopy confirmed the presence of apoptotic eosinophils in hepatic lesions at 8 and 28 dpi. At 17 wpi, apoptotic eosinophils were detected in the infiltrate surrounding some enlarged bile ducts containing adult flukes. This is the first report of apoptosis induced by F. hepatica in sheep and the first study reporting apoptosis in eosinophils in hepatic inflammatory infiltrates in vivo. The high number of apoptotic eosinophils in acute necrotic tracts during the migratory and biliary stages of infection suggests that eosinophil apoptosis may play a role in F. hepatica survival during different stages of infection.

    (1) Acute otitis media is likely in adults with recent-onset otalgia, fever, and a bulging eardrum on otoscopy. Management is similar to that in children: no antibiotics in the first instance, then amoxicillin later if antibiotic therapy is needed. (2) Otitis media with a perforated eardrum, and evidence of pus must be distinguished from external otitis. In patients with otitis media and a perforated eardrum, the commonest bacterial isolates are staphylococci, pseudomonas and pneumococci. (3) If antibiotics are prescribed the choice of agent is based on individual clinical findings and underlying health status.

    Eosinophilic esophagitis (EoE) with adults, as a new disease emerging during the last decade, is a clinicopathologic disorder of the esophagus characterized by a dense esophageal eosinophilic infiltration and typical esophageal symptoms. As numerous studies about EoE had been reported during last several years, updated consensus of EoE was reported in July 2011. The conceptual definition of EoE is coming. EoE is defined as a chronic, immune/antigen-mediated esophageal disease characterized clinically by symptoms related to esophageal dysfunction and histologically by eosinophil-predominat inflammation. Other important addition is genotyping feature that implicates thymic stromal lymphopoietin genes or filagrrin as EoE susceptibility genes. The majority of patients has the concurrent allergic disease, especially food or aeroallergen sensitization. Main therapeutic options include topical steroids and dietary modification. Recent issues of EoE include a new concept for proton pump inhibitor-responsive esophageal eosinophilia that it should be excluded to diagnose EoE.

    2016-01-01

    Eosinophilic chronic rhinosinusitis (ECRS) is considered a refractory and intractable disease. Patients with ECRS present with thick mucus production, long-term nasal congestion, loss of sense of smell, and intermittent acute exacerbations secondary to bacterial infections. Despite medical and surgical interventions, there is a high rate of recurrence with significant impairment to quality of life. The recent increasing prevalence of ECRS in south Asian countries and the strong tendency of ECRS to reoccur after surgery should be considered. The majority of cases need repeat surgery, and histological examinations of these cases show eosinophilic-dominant inflammation. The degradation and accumulation of eosinophils, release of cytokines, and mucus secretion have important roles in the pathogenesis of ECRS. ECRS differs from non-ECRS, in which eosinophils are not involved in the pathogenesis of the disease, and also in terms of many clinical characteristics, blood examination and nasal polyp histological findings, clinical features of the disease after surgery, efficacy of medications, and computed tomography findings. This review describes the clinical course, diagnosis, and treatment of ECRS as well as its pathophysiology and the role of eosinophils, mucus, cytokines, and other mediators in the pathogenesis of ECRS.

    Background Use of topical NSAIDs to treat acute musculoskeletal conditions is widely accepted in some parts of the world, but not in others. Their main attraction is their potential to provide pain relief without associated systemic adverse events. Objectives To review the evidence from randomised, double-blind, controlled trials on the efficacy and safety of topically applied NSAIDs in acute pain. Search methods We searched MEDLINE, EMBASE, The Cochrane Library, and our own in-house database to December 2009. We sought unpublished studies by asking personal contacts and searching on-line clinical trial registers and manufacturers web sites. Selection criteria We included randomised, double-blind, active or placebo (inert carrier)-controlled trials in which treatments were administered to adult patients with acute pain resulting from strains, sprains or sports or overuse-type injuries (twisted ankle, for instance). There had to be at least 10 participants in each treatment arm, with application of treatment at least once daily. Data collection and analysis Two review authors independently assessed trial quality and validity, and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Forty-seven studies were included; most compared topical NSAIDs in the form of a gel, spray, or cream with a similar placebo, with 3455 participants in the overall analysis of efficacy. For all topical NSAIDs combined, compared with placebo, the number needed to treat to benefit (NNT) for clinical success, equivalent to 50% pain relief, was 4.5 (3.9 to 5.3) for treatment periods of 6 to 14 days. Topical diclofenac, ibuprofen, ketoprofen, and piroxicam were of similar efficacy, but indomethacin and benzydamine were not significantly better than placebo. Local skin reactions were generally mild and transient, and did not differ from

    Asthma is a heterogeneous disease that can be classified into different clinical endotypes, depending on the type of airway inflammation, clinical severity, and response to treatment. This article focuses on the eosinophilic endotype of asthma, which is defined by the central role that eosinophils play in the pathophysiology of the condition. It is characterized by elevated sputum and/or blood eosinophils on at least 2 occasions and by a significant response to treatments that suppress eosinophilia. Histopathologic demonstration of eosinophils in the airways provides the most direct diagnosis of eosinophilic asthma; but it is invasive, thus, impractical in clinical practice. PMID:27401626

    Although treatment results for adult acute lymphoblastic leukemia (ALL) have improved considerably in the past decades, treating adult patients with relapsed/refractory acute lymphocytic leukemia (ALL) is still difficult. Adults with refractory/relapsed acute lymphocytic leukemia (ALL) processed to death rapidly associated with chemotherapy resistance, high mortality by reinduction, etc. Only 20% to 30% of those patients acquired complete remission (CR). Those patients are always of short duration unless an allogeneic stem cell transplant is feasible. Median survival is only ranging from 2 to 12 months. Therapeutic strategy on relapsed/refractory acute lymphocytic leukemia (ALL) is always a major therapeutic challenge bothering hematological researchers. Novel agents and unique therapeutic strategies have been developed in recent years. This review focuses on major clinical advances in the agents for refractory/relapsed ALL.

    Rehabilitation is a key component of nursing and allied healthcare professionals' roles in most health and social care settings. This paper reports on stage 2 of an action research project to ascertain older adult's experience of rehabilitation. Twenty postdischarge interviews were conducted and the interview transcripts were analysed using thematic content analysis. All older adults discharged from an acute older acute rehabilitation ward to their own homes in the community were eligible to participate. The only exclusion criterion was older adults who were thought to be unable to give consent to participate by the nurse in charge and the researcher. Whilst 92 older adults were eligible to participate in this research study, only 20 were interviewed. The findings from this study suggest that older adults valued communication with health professionals but were aware of their time constraints that hindered communication. This study suggests that both nurses and allied health professionals are not actively providing rehabilitative services to promote health and well-being, which contradicts the focus of active ageing. Furthermore, there was evidence of unmet needs on discharge, and older adults unable to recall the professions that were involved in their interventions and the rationale for therapy input. It is suggested that further research is needed to explore the effectiveness of allied health rehabilitation in the acute setting. This study highlights the need for further research into older adults' perceptions of the rehabilitation process in the acute setting.

    Nitration of tyrosine residues has been observed during various acute and chronic inflammatory diseases. However, the mechanism of tyrosine nitration and the nature of the proteins that become tyrosine nitrated during inflammation remain unclear. Here we show that eosinophils but not other cell types including neutrophils contain nitrotyrosine-positive proteins in specific granules. Furthermore, we demonstrate that the human eosinophil toxins, eosinophil peroxidase (EPO), major basic protein, eosinophil-derived neurotoxin (EDN) and eosinophil cationic protein (ECP), and the respective murine toxins, are post-translationally modified by nitration at tyrosine residues during cell maturation. High resolution affinity-mass spectrometry identified specific single nitration sites at Tyr349 in EPO and Tyr33 in both ECP and EDN. ECP and EDN crystal structures revealed and EPO structure modeling suggested that the nitrated tyrosine residues in the toxins are surface exposed. Studies in EPO-/-, gp91phox-/-, and NOS-/- mice revealed that tyrosine nitration of these toxins is mediated by EPO in the presence of hydrogen peroxide and minute amounts of NOx. Tyrosine nitration of eosinophil granule toxins occurs during maturation of eosinophils, independent of inflammation. These results provide evidence that post-translational tyrosine nitration is unique to eosinophils. PMID:18694936

    2016-01-01

    Eosinophilic gastroenteritis (EGE) is a rare disease which belongs to primary eosinophilic gastrointestinal disorders (primary EGIDs), characterized by an accumulation of eosinophils in the gastrointestinal (GI) tract and is strongly associated with atopy and allergy. The clinical presentations vary depending on the site and depth of eosinophilic intestinal infiltration. Radiology pictures may show irregular thickening of the folds, but these findings can also be present in other conditions like inflammatory bowel disease and lymphoma. The endoscopic appearance is also nonspecific. The definite diagnosis requires biopsy for histological evidence of GI eosinophilic infiltration and clinicians make the diagnosis in correlation with and by exclusion of other possible causes of eosinophilic infiltration. Because EGE is a rare disease, the treatment is based on limited case reports and clinicians' experience. Corticosteroids are the mainstay of therapy. The prognosis of EGE is relatively good when patients receive timely and proper treatment. PMID:27382945

    The case report in this review illustrates an acute myocardial infarction in a young adult probably due to arterial thrombosis that can be attributed to a hypercoagulable state resulting from the nephrotic syndrome. Although rare, acute myocardial infarction should be considered in young adults presenting with chest pain. A detailed clinical history may help to identify the aetiology, and guide subsequent management, but diagnostic coronary angiography is essential. Careful risk factor modification and treatment of the underlying cause should reduce the incidence of recurrent cardiac events. PMID:11796868

    It is well known that half of the cases admitted to hospital emergency services complain of abdominal pain and that nearly half of these cases are diagnosed with nonspecific abdominal pain. The population of patients with celiac sprue is rarely encountered at the emergency room. Although acute abdominal pain is rarely seen in adult celiac sprue, it should be added to the differential diagnosis. It should also be remembered that acute abdominal pain in these patients could be originating from perforation, intussusceptions and/or intestinal lymphoma. Herein we report a case of adult celiac sprue where successful surgical exploration was carried out because of entero-enteral intussusception. PMID:17602358

    A growing number of reports state that regular exercise enhances brain function in older adults. Recently a functional near-infrared spectroscopy (fNIRS) study revealed that an acute bout of moderate exercise enhanced activation of the left dorsolateral prefrontal cortex (L-DLPFC) associated with Stroop interference in young adults. Whether this acute effect is also applicable to older adults was examined. Sixteen older adults performed a color-word matching Stroop task before and after 10 minutes of exercise on a cycle ergometer at a moderate intensity. Cortical hemodynamics of the prefrontal area was monitored with a fNIRS during the Stroop task. We analyzed Stroop interference (incongruent-neutral) as Stroop performance. Though activation for Stroop interference was found in the bilateral prefrontal area before the acute bout of exercise, activation of the right frontopolar area (R-FPA) was enhanced after exercise. In the majority of participants, this coincided with improved performance reflected in Stroop interference results. Thus, an acute bout of moderate exercise improved Stroop performance in older adults, and this was associated with contralateral compensatory activation. PMID:22300952

    Acute symptomatic seizures are seizures occurring in close temporal relationship with an acute central nervous system (CNS) insult. The objective of the study was to determine the frequency of presentation and etiological risk factors of acute symptomatic seizures among adult medical admissions. It was a two-year retrospective study of the medical files of adults patients admitted with acute symptomatic seizures as the first presenting event. There were 94 cases of acute symptomatic seizures accounting for 5.2% (95% CI: 4.17–6.23) of the 1,802 medical admissions during the period under review. There were 49 (52.1%) males and 45 (47.9%) females aged between 18 years and 84 years. The etiological risk factors of acute symptomatic seizures were infections in 36.2% (n = 34) of cases, stroke in 29.8% (n = 28), metabolic in 12.8% (n = 12), toxic in 10.6% (n = 10), and other causes in 10.6% (n = 10). Infective causes were more among those below fifty years while stroke was more in those aged fifty years and above. CNS infections and stroke were the prominent causes of acute symptomatic seizures. This is an evidence of the “double tragedy” facing developing countries, the unresolved threat of infectious diseases on one hand and the increasing impact of noncommunicable diseases on the other one.

    Chronic eosinophilic pneumonia. The chronic eosinophilic pneumonia is part of Pulmonary Eosinophilic Syndroms. It is presented a 33-years old man, Asmathic, with dry cough, fever, night sweats and fatigue of several weeks. The chest X-ray showed opacity in the right hemithorax. He was treated with antibiotics without response. A chest TC showed multifocal involvement. The patient refused bronchoalveolar lavage (BAL) so treatment antituberculostatic was started. Despite treatment the symptoms worsened. The Chest X-ray showed migration of the infiltrates and the blood smear marked eosinophilia. Finally, bronchoalveolar lavage was carried out and it showed a high percentage of eosinophils (over 50%). The patient was treated with inmmunosuppresive doses of corticosteroids with excellent response. The blood smear in Nonresolving pneumonia is key to consider eosinophilic pneumonia, an uncommon pathology but amenable to treatment.

    AML is an aggressive hematological malignancy with highest incidence in the older adults. The adverse features of AML in the elderly, and the frailties and comorbidities frequently present in them, make their management a particularly difficult therapeutic challenge. In this context, it is important to assess carefully patient- as well as disease-associated prognostic features with validated tools. The fittest patients should be considered for curative therapy, such as bone marrow transplantation, whereas low intensity options may be more appropriate for frail patients. Here we review how to assess patients with elderly AML and the treatments options available for them. PMID:27408788

    PubMed

    2012-09-01

    Eosinophilic gastroenteritis (EGE) is characterized by dense eosinophilic inflammation of one or several digestive tract sections. The symptoms include abdominal pain, weight loss, vomiting and diarrhea. Biopsy samples taken during endoscopic examination allows the diagnosis of the disease. An infiltration of >30 eosinophils per high-power field in at least five high-power fields, exhibiting signs of eosinophilic degranulation and extending to the muscularis mucosa or submucosa are all histological indications of EGE. EGE is traditionally classified into three forms depending on the depth of inflammation in the wall (mucosal, muscular or serosal). This, together with the digestive tract segments involved, determines the clinical presentation. The natural history of EGE includes three different evolutionary patterns, since patients may suffer a single outbreak, a recurrent course or even chronic disease. Corticosteroids are the most frequently used therapy for EGE; dietary treatments should be also considered. Surgery has been limited to solving obstruction and small bowel perforation.

    Older adults presenting with acute coronary syndromes (ACSs) often have multiple chronic conditions (MCCs). In addition to traditional cardiovascular (CV) risk factors (ie, hypertension, hyperlipidemia, and diabetes), common CV comorbidities include heart failure, stroke, and atrial fibrillation, whereas prevalent non-CV comorbidities include chronic kidney disease, anemia, depression, and chronic obstructive pulmonary disease. The presence of MCCs affects the presentation (eg, increased frequency of type 2 myocardial infarctions [MIs]), clinical course, and prognosis of ACS in older adults. In general, higher comorbidity burden increases mortality following MI, reduces utilization of ACS treatments, and increases the importance of developing individualized treatment plans.

    2012-01-01

    Reports of  “eosinophilic colitis”—raised colonic mucosal eosinophil density in patients with lower gastrointestinal symptoms—have increased markedly over the last fifteen years, though it remains a rarity. There is no consensus over its diagnosis and management, and uncertainty is compounded by the use of the same term to describe an idiopathic increase in colonic eosinophils and an eosinophilic inflammatory reaction to known aetiological agents such as parasites or drugs. In patients with histologically proven colonic eosinophilia, it is important to seek out underlying causes and careful clinicopathological correlation is advised. Because of the variability of eosinophil density in the normal colon, it is recommended that histological reports of colonic eosinophilia include a quantitative morphometric assessment of eosinophil density, preferably across several sites. Few reported cases of “eosinophilic colitis” meet these criteria. As no correlation has been shown between colonic eosinophil density and symptoms in older children or adults, it is suggested that treatment should be directed towards alleviation of symptoms and response to treatment assessed clinically rather than by histological estimates of intramucosal eosinophils.

    Introduction Intestinal malrotation refers to the partial or complete failure of rotation of midgut around the superior mesenteric vessels in embryonic life. Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. Presentation of case 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating “whirpool sign”. Discussion Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. Conclusion Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality. PMID:27015011

Eosinophilic pancreatitis is one rare etiology of pancreatic eosinophilia, but other described causes of eosinophilic infiltrates have also included pancreatic allograft rejection, pancreatic pseudocyst, lymphoplasmacytic sclerosing pancreatitis (LPSP), inflammatory myofibroblastic tumor, and histiocytosis X. In this study we describe the clinicopathologic features of three new cases of eosinophilic pancreatitis and conduct a retrospective 18-year institutional review of the myriad disease processes associated with pancreatic eosinophilia. In the files of the Johns Hopkins Hospital, <1% of all pancreatic specimens had been noted to show increased numbers of eosinophils. Eosinophilic pancreatitis itself was a rare etiology for pancreatic eosinophilia, with only one in-house case over the 18-year study period and two additional referral cases. Other disease processes associated with prominent eosinophilic infiltrates were more common and included pancreatic allograft rejection (14 cases), LPSP (5 of 24 total LPSP cases evaluated), inflammatory myofibroblastic tumor (4 cases), and systemic mastocytosis (1 case). Patients with eosinophilic pancreatitis showed two distinct histologic patterns: 1) a diffuse periductal, acinar, and septal eosinophilic infiltrate with eosinophilic phlebitis and arteritis; and 2) localized intense eosinophilic infiltrates associated with pseudocyst formation. All three patients with eosinophilic pancreatitis had peripheral eosinophilia, and all had multiorgan involvement. One patient with LPSP also had marked peripheral eosinophilia, and 5 of 24 LPSP cases demonstrated prominent eosinophilic infiltrates in the gallbladder, biliary tree, and/or duodenum. Notably, not all of these patients with LPSP with prominent eosinophils in other organs had increased eosinophils in the pancreas itself. These results emphasize the infrequent nature of pancreatic eosinophilia and

    Loss of function mutations and deletions encompassing the plant homeodomain finger 6 (PHF6) gene are present in about 20% of T-cell acute lymphoblastic leukemias (ALLs). Here, we report the identification of recurrent mutations in PHF6 in 10/353 adult acute myeloid leukemias (AMLs). Genetic lesions in PHF6 found in AMLs are frameshift and nonsense mutations distributed through the gene or point mutations involving the second plant homeodomain (PHD)-like domain of the protein. As in the case of T-ALL, where PHF6 alterations are found almost exclusively in males, mutations in PHF6 were seven times more prevalent in males than in females with AML. Overall, these results identify PHF6 as a tumor suppressor gene mutated in AML and extend the role of this X-linked tumor suppressor gene in the pathogenesis of hematologic tumors.

    Eosinophilic liver infiltration is a commonly encountered focal eosinophil-related inflammation with or without necrosis, which can be seen on computed tomography (CT) in the presence of peripheral eosinophilia. Although this entity has a relatively benign course, it is related to numerable conditions for which diagnosis may be challenging and requires substantial diagnostic work-up for proper management and care of the underlying disease. We report a case of a 60-year-old man who presented with a 1-week history of right upper quadrant abdominal pain with multiple ill-defined liver hypodensities associated with significant eosinophilia.

    Background: Acute onset fever with altered mentation is a common problem encountered by the physician practicing in tropical countries. Central nervous system (CNS) infections are the most common cause resulting in fever with altered mentation in children. Aim: In this study, we have tried to analyze the cause of encephalopathy following short febrile illness in adults presenting to a tertiary care center in Northwestern part of India. Setting and Design: A prospective observational study carried out in a tertiary care center in the Northwestern India over a period of 1 year. Material and Methods A total of 127 patients with fever of less than 2 weeks duration along with alteration in mentation were studied prospectively over a period of 12 months. The demographic variables were recorded in detail. In addition to routine investigations, cerebrospinal fluid analysis, noncontrast- and contrast-enhanced computed tomography, along with magnetic resonance imaging were performed in all the subjects. Statistical Analysis The results were analyzed using SPSS statistical software. The values were expressed as mean with standard deviation for contiguous variable as percentage for the others. Results and Conclusion Out of these, 70% had primary CNS infection as the etiology. A total of 33% patients had meningitis, 29.9% had evidence of meningoencephalitis, and 12.7% were diagnosed as sepsis-associated encephalopathy. These were followed by cerebral malaria, leptospirosis, and brain abscess as the cause of febrile encephalopathy in adults. Among the noninfectious causes, acute disseminated encephalomyelitis, cortical venous thrombosis, and neuroleptic malignant syndrome were documented in 2.36% each. In 11% of the patients, the final diagnosis could not be made in spite of the extensive investigations. Our study demonstrates that acute febrile encephalopathy in adults is a heterogeneous syndrome with primary CNS infections being the commonest etiology. PMID:20930964

    Background Rubefacients (containing salicylates or nicotinamides) cause irritation of the skin, and are believed to relieve various musculoskeletal pains. They are available on prescription, and are common components in over-the-counter remedies. A non-Cochrane review in 2004 found limited evidence for efficacy. Objectives To review current evidence for efficacy and safety of topically applied rubefacients in acute and chronic painful musculoskeletal conditions in adults. Search methods Cochrane CENTRAL, MEDLINE, EMBASE, the Oxford Pain Relief Database, and reference lists of articles were searched; last search December 2008. Selection criteria Randomised, double blind, placebo or active controlled clinical trials of topical rubefacient for musculoskeletal pain in adults, with at least 10 participants per treatment arm, and reporting outcomes at close to 7 (minimum 3, maximum 10) days for acute conditions and 14 (minimum 7) days or longer for chronic conditions. Data collection and analysis Two review authors independently assessed trials for inclusion and quality, and extracted data. Relative benefit or risk and number needed to treat to benefit or harm (NNT or NNH) were calculated with 95% confidence intervals (CI). Acute and chronic conditions were analysed separately. Main results Six placebo and one active controlled studies (560 and 137 participants) in acute pain, and seven placebo and two active controlled studies (489 and 90 participants) in chronic pain were included. All used topical salicylates. The evidence in acute conditions was not robust; using only better quality, valid studies, there was no difference between topical rubefacient and topical control, though overall, including lower quality studies, the NNT for clinical success compared with placebo was 3.2 (95% CI: 2.4 to 4.9). In chronic conditions the NNT was 6.2 (95% CI: 4.0 to 13) compared with topical placebo. Adverse events and withdrawals occurred more often with rubefacients than placebo

    The molecular analysis of acute lymphoblastic leukemia (ALL) has provided exciting insights into the pathogenesis of this disease. This disease is heterogenous and can be subtyped based on chromosomal, immunophenotypic, and structural criteria. The varying prognostic implications of different ALL subtypes markedly influence the treatment decisions in adults. Many patients with T-cell ALL can be cured with chemotherapy alone. In contrast, patients with early B-lineage ALL with certain chromosomal abnormalities, especially the Philadelphia chromosome, do not have durable responses to chemotherapy and should receive a bone marrow transplantation if an HLA-matched donor is available. Recent reports have shown improved results for adults with B-cell ALL (Burkitt's) after intensive alternating cycles of chemotherapy containing high doses of methotrexate and cyclophosphamide. Future clinical and laboratory investigation should lead to the development of novel and possibly more effective treatments specifically tailored for different subsets of ALL. PMID:8775728

    While peripheral or tissue eosinophilia may certainly characterize drug eruptions, this feature is hardly pathognomonic for a medication-induced etiology. While delayed drug hypersensitivity reactions with prominent eosinophilic recruitment have been typically classified as type IVb reactions, their pathophysiology is now known to be more complex. Eosinophilic drug reactions have a diversity of presentations and may be benign and self-limited to severe and life-threatening. The extent of clinical involvement is also heterogeneous, ranging from isolated peripheral eosinophilia or single organ involvement (most often the skin and lung) to systemic disease affecting multiple organs, classically exemplified by drug-reaction with eosinophilia and systemic symptoms (DRESS). The spectrum of implicated medications in the causation of DRESS is ever expanding, and multiple factors including drug metabolites, specific HLA alleles, herpes viruses, and immune system activation have been implicated in pathogenesis. Due to this complex interplay of various factors, diagnostic workup in terms of skin and laboratory testing has not been validated. Similarly, the lack of controlled trials limits treatment options. This review also describes other localized as well as systemic manifestations of eosinophilic disease induced by various medication classes, including their individual pathophysiology, diagnosis, and management. Given the multitude of clinical patterns associated with eosinophilic drug allergy, the diagnosis can be challenging. Considerable deficits in our knowledge of these presentations remain, but the potential for severe reactions should be borne in mind in order to facilitate diagnosis and institute appropriate management.

    Background Flurbiprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID), related to ibuprofen and naproxen, used to treat acute and chronic painful conditions. There is no systematic review of its use in acute postoperative pain. Objectives To assess efficacy, duration of action, and associated adverse events of single dose oral flurbiprofen in acute postoperative pain in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to January 2009. Selection criteria Randomised, double blind, placebo-controlled trials of single dose orally administered flurbiprofen in adults with moderate to severe acute postoperative pain. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk (RR) and number needed to treat to benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals were collected. Main results Eleven studies compared flurbiprofen (699 participants) with placebo (362 participants) in studies lasting 6 to 12 hours. Studies were of adequate reporting quality, and most participants had pain following dental extractions. The dose of flurbiprofen used was 25 mg to 100 mg, with most information for 50 mg and 100 mg. The NNT for at least 50% pain relief over 4 to 6 hours for flurbiprofen 50 mg compared with placebo (692 participants) was 2.7 (2.3 to 3.3) and for 100 mg (416 participants) it was 2.5 (2.0 to 3.1). With flurbiprofen 50 mg and 100 mg 65% to 70% of participants experienced at least 50% pain relief, compared with 25% to 30% with placebo. Rescue medication was used by 25

    Eosinophilic and herpetic esophagitis are listed as independent causes of dysphagia, especially in young adult males. However, herpetic esophagitis rarely affects immunocompetent individuals. We report the case of a young, not immunocompromised patient, admitted because of severe dysphagia secondary to herpes simplex virus esophagitis. After complete resolution, an endoscopic and histologic reevaluation established the diagnosis of eosinophilic esophagitis. The potential association between the two conditions is discussed.

    Objective The microbiome has been implicated in the pathogenesis of a number of allergic and inflammatory diseases. The mucosa affected by eosinophilic esophagitis (EoE) is composed of a stratified squamous epithelia and contains intraepithelial eosinophils. To date, no studies have identified the esophageal microbiome in patients with EoE or the impact of treatment on these organisms. The aim of this study was to identify the esophageal microbiome in EoE and determine whether treatments change this profile. We hypothesized that clinically relevant alterations in bacterial populations are present in different forms of esophagitis. Design In this prospective study, secretions from the esophageal mucosa were collected from children and adults with EoE, Gastroesophageal Reflux Disease (GERD) and normal mucosa using the Esophageal String Test (EST). Bacterial load was determined using quantitative PCR. Bacterial communities, determined by 16S rRNA gene amplification and 454 pyrosequencing, were compared between health and disease. Results Samples from a total of 70 children and adult subjects were examined. Bacterial load was increased in both EoE and GERD relative to normal subjects. In subjects with EoE, load was increased regardless of treatment status or degree of mucosal eosinophilia compared with normal. Haemophilus was significantly increased in untreated EoE subjects as compared with normal subjects. Streptococcus was decreased in GERD subjects on proton pump inhibition as compared with normal subjects. Conclusions Diseases associated with mucosal eosinophilia are characterized by a different microbiome from that found in the normal mucosa. Microbiota may contribute to esophageal inflammation in EoE and GERD. PMID:26020633

    Eosinophil-associated diseases (EADs) are a diverse group of disorders characterized by an increase in circulating or tissue eosinophils. Cardiopulmonary and gastrointestinal system involvement can be due to primary EAD with no known cause or can be secondary to known systemic disease. The cardiopulmonary spectrum of EADs comprises simple pulmonary eosinophilia, acute eosinophilic pneumonia, chronic eosinophilic pneumonia, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis, bronchocentric granulomatosis, parasitic infections, and idiopathic hypereosinophilic syndrome. Eosinophilic gastrointestinal disorders include eosinophilic esophagitis, eosinophilic gastroenteritis, and eosinophilic colitis. Diagnosis is often challenging and requires a combination of clinical and imaging features along with laboratory findings. The absolute eosinophil count in peripheral blood and the percentage of eosinophils in bronchoalveolar lavage fluid are crucial in evaluation of various eosinophilic lung diseases. Although chest radiography is the initial imaging modality used in suspected cases of pulmonary EAD, multidetector computed tomography may demonstrate more characteristic pulmonary patterns, nodules, and subtle parenchymal abnormalities. Barium esophagography is used to assess mucosal abnormalities and the length and diameter of esophageal strictures. Magnetic resonance imaging is superior in providing valuable information in select patients, especially in evaluation of cardiac and gastrointestinal system involvement. Many patients require a multimodality imaging approach to enable diagnosis, guide treatment, and assess treatment response. Knowledge of the clinical features and imaging findings of the spectrum of EADs involving the lungs, heart, and gastrointestinal tract permits optimal patient care. PMID:26963455

    The appearance on magnetic resonance imaging (MRI) of 16 cases of pathologically proven eosinophilic granuloma were reviewed retrospectively and correlated with the radiographic appearance of the lesion. The most common MR appearance (ten cases) was a focal lesion, surrounded by an extensive, ill-defined bone marrow and soft tissue reaction with low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, considered to represent bone marrow and soft tissue edema (the flare phenomenon). The MRI manifestations of eosinophilic granuloma, especially during the early stages, are nonspecific, and may stimulate an aggressive lesion such as osteomyelitis or Ewings sarcoma, or other benign bone tumors such as osteoid osteoma or chondroblastoma.

    Acute lymphoblastic leukemia (ALL) is a malignant neoplasm of the lymphocyte precursor cells. Among adults it is a relatively rare neoplasm with a curability rate around 30% at 5 years. Currently, the diagnosis and classification of ALL is a multistep procedure that relies on the simultaneous application of multiple techniques that include: cytomorphology, immunophenotype and cytogenetic assays. Some of them have important clinical implications for both diagnosis and predicting response to specific treatment regimens, while the role of others is still to be defined. Over the years, several prognostic factors have been identified and today a risk stratification at diagnosis and during the follow-up is based on the characteristics of the leukemic cells.

    Limited research indicates positive affective change following acute bouts of exercise, but whether this improved affect among younger subjects may be generalized to older individuals is not known. The present study, then, examined the effects of a single bout of physical activity among older participants. 16 trained women (Mage = 64.5 +/- 7.6 yr.) completed an abbreviated Profile of Mood States prior to and immediately following a 75-min. session of aerobic line dancing. A series of one-way analyses of variance with repeated measures were used to examine differences between pre- and posttest subscores on mood states. Significant decreases following exercise in scores on Tension, Depression, Fatigue, and Anger and a significant increase in scores on Vigor relative to preexercise (control) scores were found. Global mood was significantly improved after the exercise session. No significant difference was found between pre- and postexercise measures of Confusion. Previous findings of significant improvements in affect immediately after an acute bout of exercise may be generalized to older adults. Repetition with a nonexercised control group is desirable.

    Acute pharyngitis in adults is one of the most common infectious diseases seen in general practitioners' consultations. Viral aetiology is the most common. Among bacterial causes, the main agent is Streptococcus pyogenes or group A β-haemolytic streptococcus (GABHS), which causes 5%-30% of the episodes. In the diagnostic process, clinical assessment scales can help clinicians to better predict suspected bacterial aetiology by selecting patients who should undergo a rapid antigen detection test. If these techniques are not performed, an overdiagnosis of streptococcal pharyngitis often occurs, resulting in unnecessary prescriptions of antibiotics, most of which are broad spectrum. Consequently, management algorithms that include the use of predictive clinical rules and rapid tests have been set up. The aim of the treatment is speeding up symptom resolution, reducing the contagious time span and preventing local suppurative and non-suppurative complications. Penicillin and amoxicillin are the antibiotics of choice for the treatment of pharyngitis. The association of amoxicillin and clavulanate is not indicated as the initial treatment of acute infection. Neither are macrolides indicated as first-line therapy; they should be reserved for patients allergic to penicillin. The appropriate diagnosis of bacterial pharyngitis and proper use of antibiotics based on the scientific evidence available are crucial. Using management algorithms can be helpful in identifying and screening the cases that do not require antibiotic therapy.

    Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL) has been regarded for decades as the ALL subgroup with the worse outcome. It represents the most frequent genetic subtype of adult ALL, and increases progressively with age. The introduction of tyrosine kinase inhibitors (TKIs) has enabled to obtain complete hematologic remissions (CHRs) in virtually all patients, including the elderly, to improve disease-free survival and overall survival, as well as to increase the percentage of patients who can undergo an allogeneic stem cell transplant (allo-SCT).The current management of adult Ph+ ALL patients relies on the use of a TKI with or without chemotherapy followed by an allo-SCT, which still remains the only curative option. Minimal residual disease screening is permitting not only a better stratification of patients, but has also allowed to reconsider the role of autologous stem cell transplant for a set of patients who do not have a donor or are not eligible for an allo-SCT. At present, clinical challenges are represented by the emergence of resistant mutations, particularly the gatekeeper T315I, for which alternative approaches, comprising novel TKIs or therapies based on the combination of TKI with immunotherapeutic strategies, are being considered in order to overcome resistance.

    We previously found in Giemsa-stained colorectal sections from IBD patients that eosinophilic granulocytes turned fluorescent when excited with indirect fluorescent light, while other inflammatory cells were non-fluorescent. We now studied with that method, the frequency of eosinophilic granulocytes in sections from patients with eosinophilic esophagitis (EE). Cell counting was done in consecutive sections stained with Giemsa stain using indirect fluorescence light (G-IFL setting) and with hematoxylin-eosin using transmitted light (HE-TL setting) in 5 cases of EE and in 10 consecutive cases of reflux esophagitis (RE) grade 2. In EE 45.0 eosinophils/case (range 39-51) were recorded with the G-IFL setting but only 33.4 eosinophils/case (range 28-39) with the HE-TL setting (p < 0.05). In RE cases, 3 eosinophils/case (range 2-4) were found with the G-IFL setting and 2 eosinophil/case (range 1-3) with the HE-TL setting. The G-IFL method is not only more sensitive in detecting eosinophils than the conventional HE-TL method but also quicker, since a differential cell counting is not necessary. PMID:17091778

    Presence of BB-specific antibodies in the cerebrospinal fluid (CSF) with evidence of their intrathecal production in conjunction with the white cell count in the CSF and typical clinical symptoms is the traditional diagnostic gold standard of Lyme neuroborreliosis (LNB). Few data are available on the CSF lactate concentration in European adults with the diagnosis of acute LNB. The objective of the study was to investigate the CSF changes during acute LNB. Routine CSF parameters [leukocyte count, protein, lactate and albumin concentrations, CSF/serum quotients of albumin (Q(Alb)), IgG, IgA and IgM, and oligoclonal IgG bands] and the Borrelia burgdorferi (BB)-specific antibody index were retrospectively studied in relation to the clinical presentation in patients diagnosed with acute LNB. A total of 118 patients with LNB were categorized into the following groups according to their symptoms at presentation; group 1: polyradiculoneuritis (Bannwarth's syndrome), group 2: isolated facial palsy and group 3: predominantly meningitic course of the disease. In addition to the CSF of patients with acute LNB, CSF of 19 patients with viral meningitis (VM) and 3 with neurolues (NL) were analyzed. There were 97 patients classified with definite LNB, and 21 as probable LNB. Neck stiffness and fever were reported by 15.3% of patients. Most of these patients were younger than 50 years. Polyradiculoneuritis was frequently found in patients older than 50 years. Lymphopleocytosis was found in all patients. Only 5 patients had a CSF lactate ≥3.5 mmol/l, and the mean CSF lactate level was not elevated (2.1 ± 0.6 mmol/l). The patients with definite LNB had significantly higher lactate levels than patients with probable LNB. Elevated lactate levels were accompanied by fever and headache. In the Reiber nomograms, intrathecal immunoglobulin synthesis was found for IgM in 70.2% followed by IgG in 19.5%. Isoelectric focussing detected an intrathecal IgG synthesis in 83 patients (70

    In the present study we investigated the pattern and efficacy of respiratory autoresuscitation in spontaneously breathing adult male rats across three separate anesthetic backgrounds. Each animal was administered one of three injectable anesthetics to achieve a surgical plane of anesthesia: ketamine-xylazine (KET, n=10), pentobarbital (PEN, n=10), or urethane (URE, n=10). Animals were tracheostomized and equipped with a femoral artery catheter to record airflow and arterial pressures. In response to a bout of breathing anoxic air, none of the 10 URE animals were able to mount a successful autoresuscitation response. In contrast, all KET and PEN animals survived all four consecutive anoxic exposures, restoring eupneic breathing in all cases. Moreover, only 4/10 URE animals expressed gasping breaths following the onset of respiratory arrest, and these were temporally delayed (p<0.001) and much smaller in volume (P≤0.012) compared to KET and PEN animals. URE animals showed no clear aberrations in their cardiovascular responses to anoxia, with the exception of lower arterial pulse pressures compared to either KET or PEN animals at specific points following RA. Ketamine-xylazine and pentobarbital anesthesia can be reliably and effectively used to create models for the study of autoresuscitation in adult rats. In contrast, urethane causes catastrophic failure of respiratory autoresuscitation, by delaying or outright preventing the elaboration of gasping breaths following anoxia-induced respiratory arrest. The neuronal and synaptic alterations accompanying urethane anesthesia may therefore provide a means of understanding potential pathological alterations in rhythm generation that can predispose the respiratory control system to failed autoresuscitation following an episode of acute severe hypoxemia.

    Background Treatment with rituximab has improved the outcome for patients with non-Hodgkin's lymphoma. Patients with B-lineage acute lymphoblastic leukemia (ALL) may also have the CD20 antigen, which is targeted by rituximab. Although single-group studies suggest that adding rituximab to chemotherapy could improve the outcome in such patients, this hypothesis has not been tested in a randomized trial. Methods We randomly assigned adults (18 to 59 years of age) with CD20-positive, Philadelphia chromosome (Ph)-negative ALL to receive chemotherapy with or without rituximab, with event-free survival as the primary end point. Rituximab was given during all treatment phases, for a total of 16 to 18 infusions. Results From May 2006 through April 2014, a total of 209 patients were enrolled: 105 in the rituximab group and 104 in the control group. After a median follow-up of 30 months, event-free survival was longer in the rituximab group than in the control group (hazard ratio, 0.66; 95% confidence interval [CI], 0.45 to 0.98; P=0.04); the estimated 2-year event-free survival rates were 65% (95% CI, 56 to 75) and 52% (95% CI, 43 to 63), respectively. Treatment with rituximab remained associated with longer event-free survival in a multivariate analysis. The overall incidence rate of severe adverse events did not differ significantly between the two groups, but fewer allergic reactions to asparaginase were observed in the rituximab group. Conclusions Adding rituximab to the ALL chemotherapy protocol improved the outcome for younger adults with CD20-positive, Ph-negative ALL.

    Acute lymphoblastic leukemia (ALL) in adults is a relatively rare malignancy. The typical presentation includes signs and symptoms associated with bone marrow failure, including fevers, infections, fatigue, and excessive bruising. In this article, we report an unusual systemic presentation of ALL in a previously healthy 18-year-old man. He initially presented with several-day history of nausea and vomiting, 10-pound weight loss, and right upper quadrant abdominal pain with evidence of acute hepatocellular liver injury (elevations in aspartate aminotransferase/alanine aminotransferase) and elevation in serum creatinine. Further history revealed that he just joined the Marine Corp; in preparation, he had been lifting weights and taking protein and creatine supplements. A complete serological evaluation for liver disease was negative and creatine phosphokinase was normal. His aspartate aminotransferase and alanine aminotransferase declined, and he was discharged with expected improvement. However, he returned one week later with continued symptoms and greater elevation of aminotransferases. Liver biopsy was nondiagnostic, revealing scattered portal and lobular inflammatory cells (primarily lymphocytes) felt to be consistent with drug-induced liver injury or viral hepatitis. Given his elevated creatinine, unresponsive to aggressive volume expansion, a kidney biopsy was performed, revealing normal histology. He subsequently developed an extensive left lower extremity deep venous thrombosis. Given his deep venous thrombosis, his peripheral blood was sent for flow cytometry, which revealed lymphoblasts. Bone marrow biopsy revealed 78% blasts with markers consistent with acute B-cell lymphoblastic leukemia. This report emphasizes that right upper quadrant abdominal pain with liver test abnormalities may be the initial presentation of a systemic illness such as ALL. PMID:27722178

    Eosinophilic colitis is a rare form of primary eosinophilic gastrointestinal disease that is poorly understood. Neonates and young adults are more frequently affected. Clinical presentation is highly variable depending on the depth of inflammatory response (mucosal, transmural, or serosal). The pathophysiology of eosinophilic colitis is unclear but is suspected to be related to a hypersensitivity reaction given its correlation with other atopic disorders and clinical response to corticosteroid therapy. Diagnosis is that of exclusion and differential diagnoses are many because colonic tissue eosinophilia may occur with other colitides (parasitic, drug-induced, inflammatory bowel disease, and various connective tissue disorders). Similar to other eosinophilic gastrointestinal disorders, steroid-based therapy and diet modification achieve very good and durable responses. In this paper, we present our experience with this rare pathology. Five patients (3 pediatric and 2 adults) presented with diarrhea and hematochezia. Mean age at presentation was 26 years. Mean duration of symptoms before pathologic diagnosis was 8 months. Mean eosinophil count per patient was 31 per high-power field. The pediatric patients responded very well to dietary modifications, with no recurrences. The adult patients were treated with steroids and did not respond. Overall mean followup was 22 (range, 2–48) months. PMID:21837236

    Motor activity and neuromotor function were examined in adult CD rats exposed to either carbaryl or propoxur, and behavioral effects were compared with the time course of cholinesterase inhibition. Rats received an IP injection of either 0, 2, 4, 6 or 8 mg/kg propoxur or 0, 4, 8, 16 or 28 mg/kg carbaryl in corn oil 20 min before testing. All doses of propoxur reduced 2 hr activity in a figure-eight maze, and crossovers and rears in an open field. For carbaryl, dosages of 8, 16 and 28 mg/kg decreased maze activity whereas 16 and 28 mg/kg reduced open field activity. In order to determine the time course of effects, rats received a single IP injection of either corn oil, 2 mg/kg propoxur or 16 mg/kg carbaryl, and were tested for 5 min in a figure-eight maze either 15, 30, 60, 120 or 240 min post-injection. Immediately after testing, animals were sacrificed and total cholinesterase was measured. Maximum effects of propoxur and carbaryl on blood and brain cholinesterase and motor activity were seen within 15 min. Maze activity had returned to control levels within 30 and 60 min whereas cholinesterase levels remained depressed for 120 and 240 min for propoxur and carbaryl, respectively. These results indicate that both carbamates decrease motor activity, but behavioral recovery occurs prior to that of cholinesterase following acute exposure.

    Serotonergic involvement has been implicated in preferential consumption of treat foods. We tested the effect of acute tryptophan depletion (ATD) on food consumption by overweight and lean adults with and without a history of recurrent major depressive disorder (MDD). ATD and taste-matched placebo challenges were administered double-blind in counter-balanced order. Participants were classified as lean (n = 36) or overweight (n=19) on the basis of body mass index (BMI). Total calorie, carbohydrate, protein, and sweet food consumption were assessed via a test meal 8-hours following ATD. Four food items of comparable palatability were offered as a part of the test: two sweet (one carbohydrate-rich, and one protein-rich) and two non-sweet (one carbohydrate-rich, and one protein-rich). As compared to the placebo challenge, ATD significantly increased sweet calorie intake among overweight participants and increased their propensity to consume sweet food first before any other type of food. Lean participants’ sweet calorie intake and food preference were unaffected by ATD. Findings suggest serotonergic involvement in the sweet food consumption by overweight individuals. PMID:19171315

    Background COPD exacerbations requiring intensive care unit (ICU) admission have a major impact on morbidity and mortality. Only 10%–25% of COPD exacerbations are eosinophilic. Aim To assess whether eosinophilic COPD exacerbations have better outcomes than non-eosinophilic COPD exacerbations in the ICU. Methods This retrospective observational cohort study was conducted in a thoracic, surgery-level III respiratory ICU of a tertiary teaching hospital for chest diseases from 2013 to 2014. Subjects previously diagnosed with COPD and who were admitted to the ICU with acute respiratory failure were included. Data were collected electronically from the hospital database. Subjects’ characteristics, complete blood count parameters, neutrophil to lymphocyte ratio (NLR), delta NLR (admission minus discharge), C-reactive protein (CRP) on admission to and discharge from ICU, length of ICU stay, and mortality were recorded. COPD subjects were grouped according to eosinophil levels (>2% or ≤2%) (group 1, eosinophilic; group 2, non-eosinophilic). These groups were compared with the recorded data. Results Over the study period, 647 eligible COPD subjects were enrolled (62 [40.3% female] in group 1 and 585 [33.5% female] in group 2). Group 2 had significantly higher C-reactive protein, neutrophils, NLR, delta NLR, and hemoglobin, but a lower lymphocyte, monocyte, and platelet count than group 1, on admission to and discharge from the ICU. Median (interquartile range) length of ICU stay and mortality in the ICU in groups 1 and 2 were 4 days (2–7 days) vs 6 days (3–9 days) (P<0.002), and 12.9% vs 24.9% (P<0.034), respectively. Conclusion COPD exacerbations with acute respiratory failure requiring ICU admission had a better outcome with a peripheral eosinophil level >2%. NLR and peripheral eosinophilia may be helpful indicators for steroid and antibiotic management. PMID:26392758

    Acute rhinosinusitis is a common disease with worldwide prevalence. It is a significant burden on the health services. It is most commonly caused by viruses and is self‐limiting in nature. The diagnosis of acute rhinosinusitis is clinical and sinus radiography is not indicated routinely. Most cases of acute rhinosinusitis are treated symptomatically. However, symptoms may persist beyond 10 days when secondary bacterial infection prevails. Antibiotics are reserved for moderate or severe cases or when there is development of complications of acute rhinosinusitis. This paper provides an update on the current management of acute rhinosinusitis. PMID:17551072

    Rhinosinusitis (RS) is an inflammatory disorder of the mucous membranes of the nose and paranasal sinuses, which are almost always affected concurrently. The EPOS2012 position paper initiated by the European Rhinologic Society and the European Academy of Allergy and Clinical Immunology is a recent comprehensive source on this common disease affecting approximately 20% of the population worldwide. Inflammation, not infection, is considered the cornerstone of RS, which is considered a temporal and pathophysiologic disease continuum with various subtypes. Acute rhinosinusitis is diagnosed, if typical symptoms last less than 12 weeks. It affects approximately 10% of the European population. Acute RS is further subdivided into acute viral, acute postviral and acute bacterial RS. Acute viral RS lasts less than 10 days with decreasing symptom intensity, while acute postviral RS is characterized by longer duration or a sudden increase of symptom severity around the 5th day ('double sickening'). Acute bacterial RS is assumed if 3 of the following 5 criteria are additionally met: Discoloured discharge (with unilateral predominance), severe local pain (with unilateral predominance), fever (>38ºC), elevated ESR/CRP, and 'double-sickening'. For the treatment of acute viral RS, nasal saline irrigations and OTC cold remedies are advised. In acute postviral RS, additional topical steroids are suggested. Advantages and disadvantages of antibiotic treatment in acute bacterial RS are detailed. Overall, the new EPOS position paper infers a reorientation in this area of high medical, pharmaceutical and economic relevance.

    Eosinophilic esophagitis (EoE) is a relatively new entity with a significant amount of increased recognition over the last decade. The mainstay treatments of EoE are designed to eliminate the causative allergens or to reduce their effects on the esophageal mucosa. Common treatments include dietary modification, proton pump inhibitors, systemic and topical corticosteroids, and endoscopic treatments. As the pathogenesis of EoE is explored, new and novel treatments are being studied that target specific pathways and chemokines identified in as precipitating agents of EoE. This is a rapidly evolving field with significant ongoing research and clinical studies. Our review will therefore focus on current and novel treatment approaches to the disease.

    A patient with a lifelong history of asthma and hay fever was investigated because of symptoms of esophageal spasm. Esophageal biopsies revealed elongated papillae and basal zone hyperplasia of the epithelial layer with eosinophilic infiltration of the lamina propria and muscularis mucosae. There was no evidence of reflux. Small bowel biopsies revealed a flat mucosal pattern with absent or blunted villi, tall columar surface epithelium, and eosinophilic infiltration of the lamina propria. He did not respond to a gluten-free diet. This patient is thought to have eosinophilic gatroenteritis with esophageal involvement, the first such case reported.

  3. Eosinophils in the 1990s: new perspectives on their role in health and disease.

    PubMed

    Wardlaw, A J

    1994-08-01

    Eosinophils are characterized by their unique crystalloid granules that contain four basic proteins--MBP, ECP, EDN and EPO. The cell has many common features with neutrophils but, unlike that cell type, eosinophils utilize VLA-4/VCAM-1 as an adherence pathway and have a number of other receptors not shared by neutrophils. These include recognition units for IgE (distinct from CD23), and receptors for IL-5, IL-3 and RANTES. Following stimulation with a variety of agents, eosinophils preferentially elaborate LTC4 as the major 5-lipoxygenase product of arachidonic acid and produce substantial amounts of PAF. Of particular interest is the ability of eosinophils to synthesize a number of cytokines. Thus eosinophils have marked pro-inflammatory potential. There is now convincing evidence that eosinophilia is T-cell dependent. The Th2-type cell, which selectively secretes IL-5 and IL-4, seems particularly involved. IL-5, IL-3 and GM-CSF are required for eosinophil maturation, and cause activation and prolonged survival of the mature cell. IL-5 is unique in that it promotes terminal differentiation of the committed eosinophil precursor and in vivo in mice appears to be sufficient on its own for eosinophil growth from uncommited stem cells. IL-4 selectively upregulates VCAM-1 expression on endothelial cells thus augmenting VLA-4-dependent eosinophil adhesion. The role of eosinophils in disease is complex but in general their numbers are increased in helminthic parasitic disease and atopic allergy and asthma. Eosinophil products can produce many of the pathological features of asthma, and helminthic larvae coated with immunoglobulin or complement are particularly susceptible to eosinophil-mediated cytotoxicity. Eosinopenia is often related to acute inflammation or stress. PMID:7937446

    Eosinophilic ascites is a rare feature of eosinophilic gastroenteritis. We would like to highlight this increasingly recognised diagnosis in a case of unexplained ascites. We present a challenging case of a woman aged 25 years who presented with nausea, vomiting, diarrhoea, generalised abdominal pain and swelling 8-week following delivery of her first baby. Her symptoms were primarily aggravated by eating, and she had also noticed postprandial itching and self-limiting generalised rash. She had a strong history of atopy. Physical examination revealed abdominal tenderness and distension with shifting dullness. Urticarial skin rash was noted on the face, neck, chest and abdomen. Routine biochemistry was normal apart from peripheral eosinophilia. Imaging confirmed moderate ascites. Diagnostic paracentesis showed exudative ascites with numerous eosinophils. Histology of the upper and lower gastrointestinal tract showed infiltration of the oesophageogastroduodenal and rectosigmoid mucosa with eosinophils. The patient significantly improved following a course of steroids and six-food elimination diet. PMID:27600059

    Eosinophils are recruited to the airways as a prominent feature of the asthmatic inflammatory response where they are broadly perceived as promoting pathophysiology. Respiratory virus infections exacerbate established asthma; however, the role of eosinophils and the nature of their interactions with respiratory viruses remain uncertain. To explore these questions, we established acute infection with the rodent pneumovirus, pneumonia virus of mice (PVM), in 3 distinct mouse models of Th2 cytokine–driven asthmatic inflammation. We found that eosinophils recruited to the airways of otherwise naïve mice in response to Aspergillus fumigatus, but not ovalbumin sensitization and challenge, are activated by and degranulate specifically in response to PVM infection. Furthermore, we demonstrate that activated eosinophils from both Aspergillus antigen and cytokine-driven asthma models are profoundly antiviral and promote survival in response to an otherwise lethal PVM infection. Thus, although activated eosinophils within a Th2-polarized inflammatory response may have pathophysiologic features, they are also efficient and effective mediators of antiviral host defense.

    An elderly patient, with a history of depression with psychosis, presented with breathlessness, a right exudative pleural effusion and a peripheral eosinophilia. The pleural fluid was eosinophil-rich (10% of leucocytes). Olanzapine therapy had been commenced 12 months previously. There was a family history of TB and the patient was of African origin. A full diagnostic work-up ensued including computed tomography of the thorax and local anaesthetic thoracoscopy. The pleura was unremarkable on CT and displayed bland smooth thickening at visual inspection during thoracoscopy. Pleural biopsies demonstrated chronic inflammation with eosinophils but no evidence of granulomatous inflammation or malignancy. Pleural tissue culture did not yield mycobacteria. A diagnosis of olanzapine-induced eosinophilic pleuritis was suspected and the pleural disease resolved with withdrawal of olanzapine. Eosinophilic pleural fluid is not a marker of non-malignant aetiology and eosinophilic pleural effusions require a careful and systematic diagnostic work-up. This is the second case report to identify olanzapine as a causative agent in eosinophilic pleural effusion. PMID:26029571

    Background The hypocellular variant of acute myeloid leukemia accounts for less than 10% of all cases of adult acute myeloid leukemia. It is defined by having less than 20 percent of cellular bone marrow in a biopsy at presentation. It is unclear in the literature whether the outcome of hypocellular acute myeloid leukemia differs from that of non-hypocellular acute myeloid leukemia. Design and Methods We retrospectively analyzed all the cases reported to be hypocellular acute myeloid leukemia between 2000 and 2009. A second pathology review was conducted and the diagnosis was confirmed in all cases. Results One hundred twenty-three (9%) patients were identified: patients with hypocellular acute myeloid leukemia were older than those with non-hypocellular acute myeloid leukemia (P=0.009) and more frequently presented with cytopenias (P<0.001). Forty-one patients with hypocellular acute myeloid leukemia had an antecedent hematologic disorder and 11 patients had received prior chemo-radiotherapy for non-hematopoietic neoplasms. On multivariate analysis, overall survival, remission duration and event-free survival were comparable to those of other patients with acute myeloid leukemia. Conclusions The outcome of hypocellular acute myeloid leukemia does not differ from that of non-hypocellular acute myeloid leukemia. PMID:22058194

    Bacillus cereus, which used to be considered non-pathogenic, was isolated from the blood of a patient with acute leukemia who was receiving intensive chemotherapy. Fatal bacteremia developed with a clinical syndrome of acute gastroenteritis, followed by both meningoencephalitis with subarachnoid hemorrhage and multiple liver abscesses probably caused by infective vasculitis. Surveillance stool cultures revealed colonization with the organism prior to the onset of diarrhea, and repetitive blood cultures were found to be positive. Thus, this case suggested some new important clinicopathologic features of true B. cereus bacteremia complicating acute leukemia.

    Eosinophilic esophagitis (EoE) is a chronic immune disease, characterized by a dense eosinophilic infiltrate in the esophagus, leading to bolus impaction and reflux-like symptoms. Traditionally considered a pediatric disease, the number of adult patients with EoE is continuously increasing, with a relatively higher incidence in western countries. Dysphagia and food impaction represent the main symptoms complained by patients, but gastroesophageal reflux-like symptoms may also be present. Esophageal biopsies are mandatory for the diagnosis of EoE, though clinical manifestations and proton pump inhibitors responsiveness must be taken into consideration. The higher prevalence of EoE in patients suffering from atopic diseases suggests a common background with allergy, however both the etiology and pathophysiology are not completely understood. Elimination diets are considered the first-line therapy in children, but this approach appears less effective in adults patients, who often require steroids; despite medical treatments, EoE is complicated in some cases by esophageal stricture and stenosis, that require additional endoscopic treatments. This review summarizes the evidence on EoE pathophysiology and illustrates the safety and efficacy of the most recent medical and endoscopic treatments. PMID:26600973

    2013-02-01

    Approximately 1 percent of primary care office visits are for chest pain, and 1.5 percent of these patients will have unstable angina or acute myocardial infarction. The initial goal in patients presenting with chest pain is to determine if the patient needs to be referred for further testing to rule in or out acute coronary syndrome and myocardial infarction. The physician should consider patient characteristics and risk factors to help determine initial risk. Twelve-lead electrocardiography is typically the test of choice when looking for ST segment changes, new-onset left bundle branch block, presence of Q waves, and new-onset T wave inversions. For persons in whom the suspicion for ischemia is lower, other diagnoses to consider include chest wall pain/costochondritis (localized pain reproducible by palpation), gastroesophageal reflux disease (burning retrosternal pain, acid regurgitation, and a sour or bitter taste in the mouth), and panic disorder/anxiety state. Other less common but important diagnostic considerations include pneumonia (fever, egophony, and dullness to percussion), heart failure, pulmonary embolism (consider using the Wells criteria), acute pericarditis, and acute thoracic aortic dissection (acute chest or back pain with a pulse differential in the upper extremities). Persons with a higher likelihood of acute coronary syndrome should be referred to the emergency department or hospital.

    Increases in eosinophil numbers are associated with infection and allergic diseases, including asthma, but there is also evidence that eosinophils contribute to homeostatic immune processes. In mice, the normal lung contains resident eosinophils (rEos), but their function has not been characterized. Here, we have reported that steady-state pulmonary rEos are IL-5-independent parenchymal Siglec-FintCD62L+CD101lo cells with a ring-shaped nucleus. During house dust mite-induced airway allergy, rEos features remained unchanged, and rEos were accompanied by recruited inflammatory eosinophils (iEos), which were defined as IL-5-dependent peribronchial Siglec-FhiCD62L-CD101hi cells with a segmented nucleus. Gene expression analyses revealed a more regulatory profile for rEos than for iEos, and correspondingly, mice lacking lung rEos showed an increase in Th2 cell responses to inhaled allergens. Such elevation of Th2 responses was linked to the ability of rEos, but not iEos, to inhibit the maturation, and therefore the pro-Th2 function, of allergen-loaded DCs. Finally, we determined that the parenchymal rEos found in nonasthmatic human lungs (Siglec-8+CD62L+IL-3Rlo cells) were phenotypically distinct from the iEos isolated from the sputa of eosinophilic asthmatic patients (Siglec-8+CD62LloIL-3Rhi cells), suggesting that our findings in mice are relevant to humans. In conclusion, our data define lung rEos as a distinct eosinophil subset with key homeostatic functions. PMID:27548519

    2009-01-01

    Introduction Inflammatory eosinophilic pseudotumor of the bladder is a rare inflammatory bladder disease. The etiology and pathophysiology of this condition are still unclear. Few case reports have described inflammatory eosinophilic pseudotumor of the bladder in adults or children. Although benign, this disease is occasionally clinically aggressive and locally invasive, thus open surgical removal or complete transurethral resection is recommended. Case presentation We present the case of a biopsy-proven inflammatory eosinophilic pseudotumor of the bladder in a previously healthy 16-year-old male adolescent with 2-month history of frequent micturition and dysuria with no significant apparent causative factors. The tumor regressed after a 6-week course of glucocorticosteroids. Conclusion To the best of our knowledge, our case is a rare case of inflammatory eosinophilic pseudotumor of the bladder treated with complete conservative management. Due to its glucocorticosteroid-sensitive nature, we postulate that this disease belongs to a subgroup of eosinophilic disorders. PMID:20062774

    2014-02-01

    Extracorporeal life support (ECLS) is an artificial means of maintaining adequate oxygenation and carbon dioxide elimination to enable injured lungs to recover from underlying disease. Technological advances have made ECLS devices smaller, less invasive, and easier to use. ECLS might, therefore, represent an important step towards improved management and outcomes of patients with acute respiratory distress syndrome. Nevertheless, rigorous evidence of the ability of ECLS to improve short-term and long-term outcomes is needed before it can be widely implemented. Moreover, how to select patients and the timing and indications for ECLS in severe acute respiratory distress syndrome remain unclear. We describe the physiological principles, the putative risks and benefits, and the clinical evidence supporting the use of ECLS in patients with acute respiratory distress syndrome. Additionally, we discuss controversies and future directions, such as novel technologies and indications, mechanical ventilation of the native lung during ECLS, and ethics considerations.

    In the treatment of adult patients with acute rhinosinusitis, it has been assumed that subjects over 65 years of age or living with children attending a day nursery, are at higher risk for infection with drug-resistant bacteria. However there are few reports which have discussed the relationship between those risk factors and adult patients with acute rhinosinusitis. I investigated the association between adult patients with acute rhinosinusitis living with children attending a day nursery and gender, ages, and frequency of detection of drug-resistant bacteria. From 2010 to 2012, a total of 598 adult patients with acute rhinosinusitis were enrolled. The majority of the study subjects were women, and the largest 10-year age group was 30-39 years. By sex, a greater proportion of the female subjects than the male subjects lived with children attending a day nursery. By age, the proportion of subjects who lived with children attending a day nursery was significantly higher in the 30-39-year age group than other age groups. Drug-resistant Streptococcus pneumoniae and ampicillin (ABPC)-resistant Haemophilus influenzae were detected at significantly higher rates in subjects with children attending a day nursery than in those without. There were no significant difference in drug-resistant bacteria detection between subjects over 65 years of age, and under 65 years. These findings suggested that living with children attending a day nursery is a risk factor and source of infection by drug-resistant organisms that may cause intra-familial infections of adult patients with acute rhinosinusitis. These results suggested we must ask adult patients with acute rhinosinusitis whether they are living with children attending a day nursery or not, when we plan their treatment strategy.

    In this study, we aimed to investigate the pathways of recognition of acute lymphoblastic leukemia blasts by natural killer cells and to verify whether differences in natural killer cell activating receptor ligand expression among groups defined by age of patients, or presence of cytogenetic/molecular aberrations correlate with the susceptibility to recognition and killing. We analyzed 103 newly diagnosed acute lymphoblastic leukemia patients: 46 adults and 57 children. Pediatric blasts showed a significantly higher expression of Nec-2 (P=0.03), ULBP-1 (P=0.01) and ULBP-3 (P=0.04) compared to adult cells. The differential expression of these ligands between adults and children was confined to B-lineage acute lymphoblastic leukemia with no known molecular alterations. Within molecularly defined subgroups of patients, a high surface expression of NKG2D and DNAM1 ligands was found on BCR-ABL(+) blasts, regardless of patient age. Accordingly, BCR-ABL(+) blasts proved to be significantly more susceptible to natural killer-dependent lysis than B-lineage blasts without molecular aberrations (P=0.03). Cytotoxic tests performed in the presence of neutralizing antibodies indicated a pathway of acute lymphoblastic leukemia cell recognition in the setting of the Nec-2/DNAM-1 interaction. These data provide a biological explanation of the different roles played by alloreactive natural killer cells in pediatric versus adult acute lymphoblastic leukemia and suggest that new natural killer-based strategies targeting specific subgroups of patients, particularly those BCR-ABL(+), are worth pursuing further.

  18. Impact of prenatal and acute methamphetamine exposure on behaviour of adult male rats.

    Psychostimulants have been shown to alter behaviour in both rats and humans. The aim of the present study was: (1) to assess the effect of prenatal and acute methamphetamine (MA) administration on behaviour in adult male rats and (2) to find out if the prenatal exposure to MA increases sensitivity to acute MA application in adulthood. Behaviour of adult male rats prenatally exposed to MA (5 mg/kg) or no drug was tested in Open field (OF) and Elevated plus maze (EPM). Half of the animals were injected with MA (1 mg/kg) subcutaneously 30 minutes prior to testing. Locomotion, exploration, comforting behaviour and anxiety were evaluated in the OF, while anxiety and exploratory behaviour were assessed in the EPM. Our results showed that prenatal MA did not have an effect on baseline behaviour in either of the tests. By contrast, acute MA increased overall psychomotor activity by increasing locomotion and exploratory behaviour and decreasing comforting behaviour. Moreover, adult rats prenatally exposed to MA were more sensitive to the effects of acute MA on exploration. In addition, acute MA application decreased anxiety in the OF as well as in the EPM. Our present study, thus, demonstrates that acute MA increases overall psychomotor activity and decreases anxiety to novel environment. To further support our hypothesis that prenatal MA exposure increases sensitivity to drugs in adulthood, studies investigating the levels of dopamine in the rat brain after prenatal MA exposure are planned.

  19. Allergic Mechanisms in Eosinophilic Esophagitis

    2014-01-01

    Paralleling the overall trend in allergic diseases, Eosinophilic Esophagitis is rapidly increasing in incidence. It is associated with food antigen-triggered, eosinophil-predominant inflammation and the pathogenic mechanisms have many similarities to other chronic atopic diseases, such as eczema and allergic asthma. Studies in animal models and from patients over the last 15 years have suggested that allergic sensitization leads to food-specific IgE and T-helper lymphocyte type 2 cells, both of which appear to contribute to the pathogenesis along with basophils, mast cells, and antigen-presenting cells. This review will outline our current understandings of the allergic mechanisms that drive eosinophilic esophagitis, drawing from clinical and translational studies in humans as well as experimental animal models.

    2007-01-01

    Acute encephalitis is an inflammation of brain tissue that can result from activity in the central nervous system (CNS) of a number of viruses. Although the neurological and psychiatric effects of encephalitis in the acute phase of the illness are well-known (Caroff, Mann, Gliatto, Sullivan, & Campbell, 2001), larger scale studies of the pattern of neuropsychological and psychiatric impairment following recovery from the acute inflammatory phase are less apparent. This paper reports the results of neuropsychological testing with a range of standardised cognitive measures in a case series of long-term post-acute participants. Psychiatric abnormality is examined using the SCL-90-R self-report scale of distress (Derogatis, 1983). We also examined the role of emerging insight in the aetiology of depression in this population. Two clusters of cognitive dysfunction were observed, one group of primarily herpes simplex cases showing a severe generalised deficit across a number of cognitive domains and a second cluster showing a variety of more isolated disorders of executive function. Abnormally high levels of distress were reported by participants, with depression, obsessive-compulsive symptoms, interpersonal sensitivity and phobic anxiety most significantly increased. Depression was found to be least severe in those with most accurate insight into their problems. Examining the correlations between cognitive and psychiatric test results demonstrates a relationship between depression and interpersonal anxiety and specific cognitive measures. Obsessive-compulsive behaviour and phobic anxiety, however, appear to exist independently of the assessed cognitive deficits.

    Eight groups of male adolescent and adult spontaneous hyperactive rats (SHR) were used in a dose response (saline, 0.6, 2.5, and 10 mg/kg) experiment of methylphenidate (MPD). Four different locomotor indices were recorded for 2 hours postinjection using a computerized monitoring system. Acutely, the 0.6 mg/kg dose of MPD did not elicit an increase in locomotor activity in either the adolescent or in the adult male SHR. The 2.5 and the 10.0 mg/kg doses increased activity in the adolescent and the adult rats. Chronically, MPD treatment when comparing adolescent and adult gave the following results: the 0.6 mg/kg dose of MPD failed to cause sensitization in the adolescent group but caused sensitization in the adult group, while the 2.5 and 10 mg/kg both caused sensitization in the adolescent and adult groups.

    Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by esophageal dysfunction and eosinophilic infiltrate (≥15/hpf) in the esophageal epithelium and the absence of other potential causes of eosinophilia. The prevalence is increasing and is the most common cause of solid food dysphagia in children and young adults. This article will review the diagnosis and management of EoE based on consensus conferences, systematic reviews, and meta-analysis and highlights seminal studies in our evolving treatment of this disease. However, all answers are not available and I will remark about the lessons learned in my clinical practice seeing EoE patients over the last 25 years. The complicated etiology of the complaint of dysphagia in EoE patients will be reviewed. The importance of utilizing endoscopy, biopsies, and barium esophagram to help define the 2 phenotypes (inflammatory, fibrostenosis) of EoE will be highlighted. The controversy about PPI-responsive esophageal eosinophilia will be discussed and contrasted with idiopathic EoE. Finally, the 3 treatment options for EoE (drugs, diet, dilation) will be reviewed in detail and a useful clinical management algorithm presented.

    Background Eosinophilic endomyocarditis (EEM) is a rare diagnosis that is extremely uncommon in newborns. This case report aimed to present a case of neonatal mortality from acute cardiac failure due to EEM. Case Our report presents a term male neonate with minor complications in the immediate postnatal course, who was discharged at 48 hours of life, but who developed unexpected respiratory distress, followed by cardiac arrest and death at 3 days of life. One day after discharge, the infant developed respiratory distress and cool skin, and then developed cardiac arrest at the pediatrician's office, undergoing resuscitation with intravenous fluid, cardiopulmonary resuscitation, epinephrine, atropine, and failed intubation. Autopsy revealed EEM, an inflammatory infiltrative process involving the endomyocardium. Pathology Pathogenesis involves three stages: (1) myocarditis with an acute eosinophilic inflammatory infiltrate followed by (2) myocyte necrosis and eventually (3) fibrosis in the final stage of the disease. Discussion The cause of death was acute cardiac failure due to intense eosinophilic infiltration and degranulation with early subendocardial myocyte necrosis but before development of extensive myocyte necrosis. This case appears to be the youngest patient reported with EEM. PMID:26495174

    Eosinophilic vasculitis has been described as part of the Churg–Strauss syndrome, but affects the central nervous system (CNS) in <10% of cases. A 39-year-old woman with a history of migraine without aura presented to an institution in an acute confusional state with concurrent headache and left-sided weakness. Laboratory evaluation showed an increased cerebrospinal fluid (CSF) protein level, but otherwise unremarkable serologies. Magnetic resonance imaging showed bifrontal polar gyral-enhancing brain lesions. Her symptoms resolved over two weeks without residual deficits. Eighteen months later the patient presented with similar symptoms and neuroradiological findings showed involvement of territories different from those in her first episode. Brain biopsy showed transmural, predominantly eosinophilic, inflammatory infiltrates and fibrinoid necrosis without granulomas. She improved when treated with corticosteroids. To our knowledge, this is the first case of non-granulomatous eosinophilic vasculitis isolated to the CNS. No aetiology for this patient’s primary CNS eosinophilic vasculitis has yet been identified.

    2011-01-01

    Introduction Intracranial vascular complications are an important complication of acute bacterial meningitis. Ischemic stroke in meningitis is reported as a result of vasculitis, vasospasm, endocarditis or intraarterial thrombosis. The aim of the study was to identify the value of measuring cerebral blood flow velocity (CBFv) on transracranial doppler (TCD) in the identification of patients at risk for meningitis-associated stroke. Methods We retrospectively studied patients with acute bacterial meningitis who were treated in our university hospital from 2000 to 2009. Data were analyzed with the main focus on the incidence of an increase of CBFv on TCD, defined as peak systolic values above 150 cm/s, and the development of stroke. Results In total, 114 patients with acute bacterial meningitis were treated, 94 of them received routine TCD studies during their hospital stay. 41/94 patients had elevated CBFv values. This increase was associated with an increased risk of stroke (odds ratio (95% confidence intervall) = 9.15 (1.96-42.67); p < 0.001) and unfavorable outcome (Glasgow Outcome Score < 4; odds ratio (95% confidence intervall) = 2.93 (1.23-6.98); p = 0.018). 11/32 (34.4%) patients with an increase of CBFv who received nimodipine and 2/9 (22.2%) patients with an increase of CBFv who did not receive nimodipine developed stroke (p = 0.69). Conclusions In summary, TCD was found to be a valuable bedside test to detect arterial alterations in patients with bacterial meningitis. These patients have an increased risk of stroke.

    Background Carbamazepine is used to treat chronic neuropathic pain. Objectives Evaluation of analgesic efficacy and adverse effects of carbamazepine for acute and chronic pain management (except headaches). Search methods Randomised controlled trials (RCTs) of carbamazepine in acute, chronic or cancer pain were identified, searching MEDLINE, EMBASE, SIGLE and Cochrane CENTRAL to June 2010, reference lists of retrieved papers, and reviews. Selection criteria RCTs reporting the analgesic effects of carbamazepine. Data collection and analysis Two authors independently extracted results and scored for quality. Numbers needed to treat to benefit (NNT) or harm (NNH) with 95% confidence intervals (CI) were calculated from dichotomous data for effectiveness, adverse effects and adverse event withdrawal. Issues of study quality, size, duration, and outcomes were examined. Main results Fifteen included studies (12 cross-over design; three parallel-group) with 629 participants. Carbamazepine was less effective than prednisolone in preventing postherpetic neuralgia following acute herpes zoster (1 study, 40 participants). No studies examined acute postoperative pain. Fourteen studies investigated chronic neuropathic pain: two lasted eight weeks, others were four weeks or less (mean 3 weeks, median 2 weeks). Five had low reporting quality. Ten involved fewer than 50 participants; mean and median maximum treatment group sizes were 34 and 29. Outcome reporting was inconsistent. Most placebo controlled studies indicated that carbamazepine was better than placebo. Five studies with 298 participants provided dichotomous results; 70% improved with carbamazepine and 12% with placebo. Carbamazepine at any dose, using any definition of improvement was significantly better than placebo (70% versus 12% improved; 5 studies, 298 participants); relative benefit 6.1 (3.9 to 9.7), NNT 1.7 (1.5 to 2.0). Four studies (188 participants) reporting outcomes equivalent to 50% pain reduction or more

    2012-08-15

    Rabbit hemorrhagic disease virus (RHDV) is the etiologic agent of rabbit hemorrhagic disease (RHD), an acute lethal infection that kills 90% of adult rabbits due to severe acute liver inflammation. Interestingly, young rabbits are naturally resistant to RHDV infection. Here, we have compared naturally occurring CD4(+)Foxp3(+) regulatory T cells (Tregs) between young and adult rabbits after infection by RHDV. The number and frequency of Tregs was decreased in the spleen of adult rabbits 24h after the RHDV infection; this was in contrast with the unchanged number and frequency of splenic Tregs found in young rabbits after the same infection. Also, serum levels of IL-10 and TGF-β were enhanced in the infected adult rabbits whereas no alteration was observed in infected young rabbits. However, this increase is accompanied by a burst of pro-inflammatory cytokines, but seems not able to prevent the death of the animals with severe acute liver inflammation in few days after infection. Since Tregs downregulate inflammation, we conclude that their decrease may contribute to the natural susceptibility of adult rabbits to RHDV infection.

    Emergency departments (EDs) provide a disproportionate amount of care to disenfranchised and vulnerable populations. We examined social support levels among a diverse population of adults seeking ED care for acute respiratory tract infections. A convenience sample of adults seeking care in 1 of 15 US EDs was telephone interviewed 1 to 6 weeks postvisit. The Multidimensional Scale of Perceived Social Support (7-point Likert) assessed social support across 3 domains: friends, family, and significant others. Higher scores indicate higher support. Of 1104 subjects enrolled, 704 (64%) completed the follow-up interview. Factor analysis yielded 3 factors. Mean social support score was 5.54 (SD 1.04). Female sex, greater household income, and better health status were independently associated with higher levels of social support. Social support levels among adults seeking care in the ED for acute respiratory tract infections are similar to general population cohorts, suggesting that social support is not a strong determinant of health care seeking in EDs.

    Cytological examination of conjunctival scrapings is a valuable technique in differentiating various types of conjunctivitis. Brush conjunctival cytology is easy to use, and it may show a rich cell sample also from the deeper conjunctival layers. It is atraumatic and suitable for tarsal conjunctival cytology. The Papanicolaou staining can be used for examination of epithelial cells and inflammatory cells. The semiquantitative counting method is rapid to use and gives some information about the severity and nature of the inflammation. Our modified method identifies the presence of eosinophils which are the hallmark both in allergic conjunctivitis and in non-allergic eosinophilic conjunctivitis (NAEC). NAEC is quite common affecting in most cases middle-aged or older people with the majority being women. NAEC is often connected with dry eye which in many cases can be seen in conjunctival cytology.

  1. Central venous catheter infection in adults in acute hospital settings.

    PubMed

    Jones, Clare A

    As well as the human cost, central venous catheter (CVC)-related bloodstream infections significantly inflate hospital costs, mainly through increased length of stay in hospital, particularly in intensive care. This literature review appraises recent research on measures used to minimize CVC-related infection and compares it with current best practice. Randomized controlled trials and systematic reviews published on the subject between 2000 and 2005 were reviewed, concentrating on non-tunnelled, short-term CVCs in the acute hospital setting. The new evidence mainly backs up current best practice. However, skin disinfection could be improved by using alcoholic chlorhexidine followed by aqueous povidone-iodine before CVC insertion. Also, alcoholic chlorhexidine is the preferred solution for cleaning the hubs/connectors before accessing the CVC. Good hand hygiene and quality control and education programmes are vital to improve patient care. More research is needed to clarify the effectiveness of certain interventions and technologies, such as antimicrobial CVCs.

    2007-01-01

    Background Eosinophilic vasculitis has been described as part of the Churg–Strauss syndrome, but affects the central nervous system (CNS) in <10% of cases; presentation in an isolated CNS distribution is rare. We present a case of eosinophilic vasculitis isolated to the CNS. Case report A 39‐year‐old woman with a history of migraine without aura presented to an institution (located in the borough of Queens, New York, USA; no academic affiliation) in an acute confusional state with concurrent headache and left‐sided weakness and numbness. Laboratory evaluation showed increased cerebrospinal fluid (CSF) protein level, but an otherwise unremarkable serological investigation. Magnetic resonance imaging showed bifrontal polar gyral‐enhancing brain lesions. Her symptoms resolved over 2 weeks without residual deficit. After 18 months, later the patient presented with similar symptoms and neuroradiological findings involving territories different from those in her first episode. Again, the CSF protein level was high. She had a raised C reactive protein level and erythrocyte sedimentation rate. Brain biopsy showed transmural, predominantly eosinophilic, inflammatory infiltrates of medium‐sized leptomeningeal arteries without granulomas. She improved, without recurrence, when treated with a prolonged course of corticosteroids. Conclusions To our knowledge, this is the first case of non‐granulomatous eosinophilic vasculitis isolated to the CNS. No aetiology for this patient's primary CNS eosinophilic vasculitis has yet been identified. Spontaneous resolution and recurrence of her syndrome is an unusual feature of the typical CNS vasculitis and may suggest an environmental epitope with immune reaction as the cause. PMID:16926236

    Background: The aim of this study was to evaluate acute neuropsychiatric disorders in adolescents and young adults with Down syndrome. We report 13 Japanese adolescents or young adults with Down syndrome who developed acute neuropsychiatric disorders including withdrawal, depression, obsessive-compulsive behaviors, and occasional delusions or hallucinations. Methods: The following information was collected from each patient: age at onset of acute neuropsychiatric disorder, complications, signs and symptoms, personality traits before the onset of the acute neuropsychiatric disorder, prescribed medications with their respective doses and the response to treatment, and senile changes observed on magnetic resonance imaging or computed tomography. Results: The mean age at onset of these disorders was 21.2 years. Brain imaging showed almost senile changes; patients responded well to low-dose psychotropic therapy. Patients had an onset at a young age and presented with treatable conditions, although the average age of the onset of Alzheimer’s disease is generally over 40 years of age in patients with Down syndrome. Conclusion: These findings suggest that the pathology of acute neuropsychiatric disorder in patients with Down syndrome may be related to presenile changes; however, these disorders present features and a clinical course that is different from those presented in typical Alzheimer’s disease with Down syndrome.

    The purpose of the present study was to examine the acute effects of resting, aerobic exercise practised alone, and aerobic exercise with active video games (AVG), on complex reaction time (CRT) and the post-exercise acute rate of perceived exertion (RPE) in young healthy adults. The experimental group was composed of 92 healthy young adults, 78 males and 13 females (age M = 21.9 ± 2.7 years) who completed two sessions, A and B. In session A, participants rode 30 min on an ergometer, while in session B they exercised for 30 min on an ergometer while playing an AVG on a Wii. The control group was composed of 30 young adults, 26 males and 4 females (age M = 21.4 ± 2.9 years) who rested for 30 min. In each session, a CRT task was performed before and after exercising or resting, and post-exercise global RPE was noted. Repeated measures general linear model (GLM) and Wilcoxon tests were performed. (1) Both aerobic exercise alone and aerobic exercise combined with AVG improved CRT, while resting did not; (2) aerobic exercise combined with AVG did not improve CRT more than aerobic exercise only; and (3) RPE was lower after aerobic exercise combined with AVG compared with aerobic exercise only. In young adults, exercise produces acute benefits on CRT, and practising exercise with AVG helps to decrease RPE.

    A 14-year-old female domestic shorthair cat was presented to Tehran University Veterinary Teaching Hospital for a persistent fever, anorexia, intermittent vomiting, weight loss and weakness. The main clinical signs were pale mucous membranes, dehydration and splenomegaly. The complete blood count and serum biochemistry tests revealed non-regenerative anaemia, thrombocytopenia and increased alkaline phosphatase (ALP) activity. An enzyme-linked immunosorbent assay (ELISA) test for feline leukaemia virus was negative. Blood film and bone marrow examination revealed a large number of immature eosinophils with variable sizes and numbers of faintly azurophilic granules. Cytochemical staining of blood film demonstrated 70% positive cells for ALP activity. Four percent CD34 positive cells were detected by flow cytometry. As eosinophilic leukaemia is difficult to identify by light microscopy, well-defined diagnostic criteria and the use of flow cytometry and cytochemical staining can improve the ability to correctly diagnose this type of leukaemia in cats.

    Eosinophilic meningitis, caused by the nematode Angiostrongylus cantonensis, is prevalent in northeastern Thailand, most commonly in adults. Data regarding clinical manifestations of this condition in children is limited and may be different those in adults. A chart review was done on 19 eosinophilic meningitis patients aged less than 15 years in Srinagarind Hospital, Faculty of Medicine, Khon Kaen University, Thailand. Clinical manifestations and outcomes were reported using descriptive statistics. All patients had presented with severe headache. Most patients were males, had fever, nausea or vomiting, stiffness of the neck, and a history of snail ingestion. Six patients had papilledema or cranial nerve palsies. It was shown that the clinical manifestations of eosinophilic meningitis due to A. cantonensis in children are different from those in adult patients. Fever, nausea, vomiting, hepatomegaly, neck stiffness, and cranial nerve palsies were all more common in children than in adults.

    Background Between one and two of every five hospitalized older adults have cognitive deficits, often not accurately assessed or well managed. Cognitive impairment adds substantially to the complexity of these patients’ care, places them at high risk for poor outcomes and increases the cost of health care. Methods We describe three evidence-based interventions, each capitalizing on the unique contributions of nurses and designed to improve outcomes of hospitalized older adults who have cognitive deficits. Interventions of varying intensity were compared across three hospitals (Phase I) and subsequently within the same hospitals (Phase II). All enrolled patients were screened during their index hospitalizations and cognitive deficits were communicated to relevant health care team members (Augmented Standard Care-ASC, lowest intensity). At one hospital, ASC was the only intervention. Patients at a second hospital also had care influenced by specially prepared registered nurses (Resource Nurse Care-RNC, medium intensity). Finally, patients at third hospital also received advanced practice nurse coordinated care (Transitional Care Model-TCM, higher intensity). In Phase II, newly enrolled patients at these same hospitals all received the TCM. We summarize major themes from review of multiple data sources and researcher recollections related to facilitators and barriers to implementing a complex research study. Findings Effective implementation of the three intervention strategies depended on clinician engagement and communication; degree of participation by nurses in the educational program with subsequent practice improvement; and success of advanced practice nurses in implementing the TCM with both with patients, family caregivers and clinicians. Implications Based on lessons learned in implementing complex research studies within the “real world” of clinical practice settings, recommendations focus on strengthening facilitators, minimizing barriers and gaining

    The outcome of patients with acute promyelocytic leukaemia (APL) has dramatically improved over the last two decades, due to the introduction of combined all-trans retinoic acid (ATRA) and chemotherapy regimens and, more recently, to the advent of arsenic trioxide (ATO). ATRA and anthracycline-based chemotherapy remains a widely used strategy, providing cure rates above 80%, but it is associated with risk of severe infections and occurrence of secondary leukaemias. ATO is the most effective single agent in APL and, used alone or in combination with ATRA or ATRA and reduced-intensity chemotherapy, results in greater efficacy with considerably less haematological toxicity. The toxic profile of ATO includes frequent, but manageable, QTc prolongation and increase of liver enzymes. Two large randomized studies have shown that ATRA + ATO is superior to ATRA + chemotherapy for newly diagnosed low-risk APL resulting in 2-4 year event-free survival rates above 90% and very few relapses. According to real world data, the spectacular progress in APL outcomes reported in clinical trials has not been paralleled by a significant improvement in early death rates, this remains the most challenging issue for the final cure of the disease.

    A study of the thymidine labelling index (TLI) of bone marrow blast cells in 58 untreated patients with acute myelogenous leukemia showed no correlation with remission rate but there was a strong correlation between labelling index and remission length in the 21 patients who achieved remission. The median remission length of the patients was 33 weeks. Of the 12 patients with initial labelling indices greater than 10%, only 2 had remissions longer than 33 weeks whereas 8 of the 9 patients with labelling indices less than 10% had remissions longer than 33 weeks. No correlation could be found between the degree of cytological differentiation and remission induction, remission length or survival. No correlation was found between the TLI and the degree of cytological differentiation. Age and initial platelet count were confirmed to be important factors influencing complete remission rate, but these factors did not correlate with remission length. Sixteen patients had their pretreatment sera assayed for mouse marrow colony stimulating activity and inhibitor levels but there was no correlation with subsequent response to treatment, although the number of patients examined was clearly too small for any definite conclusions to be drawn.

    Severe acute respiratory syndrome (SARS) is a newly described respiratory infection with pandemic potential. The causative agent is a new strain of coronavirus most likely originating from wild animals. This disease first emerged in November 2002 in Guangdong Province, China. Early in the outbreak the infection had been transmitted primarily via household contacts and healthcare settings. In late February 2003 the infection was transmitted to Hong Kong when an infected doctor from the mainland visited there. During his stay in Hong Kong at least 17 guests and visitors were infected at the hotel at which he stayed. By modern day air travel, the infection was rapidly spread to other countries including Vietnam, Singapore and Canada by these infected guests. With the implementation of effective control strategies including early isolation of suspected cases, strict infection control measures in the hospital setting, meticulous contact tracing and quarantine, the outbreak was finally brought under control by July 2003. In addition, there were another two events of SARS in China between the end of December 2003 and January 2004 and from March to May 2004; both were readily controlled without significant patient spread.

    Combination of bronchial asthma and gastrointestinal pathology is frequently encountered in clinical practice. Clinical symptoms of this condition are highly diversified and gastrointestinal diseases play an important role in exacerbation of bronchial asthma. The prevalence of allergic diseases has recently become rampant. Eosinophilic oesophagitis is worth of special attention because its histological criteria, unlike clinical ones, are well defined. They include chronic immune antigen-mediated inflammatory oesophageal disease with pronounced intraepithelial eosinophilic infiltration and clinical symptoms resulting from oesophageal dysfunction that resemble manifestations of gastroesophageal reflux disease but fail to respond to antireflux and antacid therapy. Many specific and practical aspects of the problem remain to be elucidated. The poor awareness of clinicians of this disease hampers its adequate diagnostics and treatment. In order to revise and optimize the former diagnostic and therapeutic algorithm., an interdisciplinary expert group was set up in 2010 constituted by specialists of the American College of Gastroenterology, American Academy of Asthma, Allergy and Immunology, and Society of Pediatric Gastroenterology, Hepatology, and Nutrition. Results of the work of this group together with the literature data on eosinophilic esopahgitis are discussed in the present review. PMID:23516863

    Eosinophilic fasciitis is a systemic inflammatory disease characterized by symmetrical swelling and skin induration of the distal portions of the arms and/or legs, evolving into a scleroderma-like appearance, accompanied by peripheral blood eosinophilia. It is a rare disease with a poorly understood etiology. Corticosteroid treatment remains the standard therapy, either taken alone or in association with an immunosuppressive drug. This paper presents a case of a male patient with palpebral edema and marked eosinophilia, diagnosed with intestinal parasitic infection in October 2006. He was treated with an antiparasitic drug, but both the swelling and the analytical changes remained. This was followed by a skin and muscle biopsy, which turned out to be compatible with eosinophilic fasciitis. There was progressive worsening of the clinical state, with stiffness of the abdominal wall and elevated inflammatory parameters, and the patient was referred to the Immunology Department, medicated with corticosteroids and methotrexate. Over the years there were therapeutic adjustments and other causes were excluded. Currently the patient continues to be monitored, and there is no evidence of active disease. The case described in this article is interesting because of the diagnosis of eosinophilic fasciitis probably associated/coexisting with a parasite infection. This case report differs from others in that there is an uncommon cause associated with the onset of the disease, instead of the common causes such as trauma, medication, non-parasitic infections or cancer.

    Abstract Introduction: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by a marked eosinophilic infiltrate in the esophageal mucosa. What was once considered a rare disease has nowadays become one of the most frequent esophageal diseases in the Western countries, occupying a place just next to the gastroesophageal reflux disease. EoE etiology and pathogenesis remain largely unknown, although most studies consider that allergic and genetic factors play the most important role. Methods: We report the case of EoE in an elderly male (octogenarian), giving a brief review of the current data related to epidemiology, pathogenesis, diagnosis, and treatment of the disease. Results: Dysphagia to solid foods was the leading symptom, and endoscopic findings included white exudates, longitudinal furrows, and concentric mucosal rings, all suggestive for EoE. Diagnosis relied on histological findings in esophageal mucosal biopsies (>30 eosinophils per high power field). He was treated with topical steroids for 8 weeks, symptoms improved gradually and the patient remained in remission at the 8-month follow-up. Conclusion: This case emphasizes that EoE may occur in very old patients and gastroenterologists should have a high index of suspicion of this disorder in any elderly with dysphagia and endoscopic relevant features.

    Although acute myeloid leukemia (AML) is primarily a disease of older adults (age ≥60 years), the optimal treatment for older adults remains largely undefined. Intensive chemotherapy is rarely beneficial for frail older adults or those with poor-risk disease, but criteria that define fitness and/or appropriateness for intensive chemotherapy remain to be standardized. Evaluation of disease-related and patient-specific factors in the context of clinical decision making has therefore been largely subjective. A uniform approach to identify those patients most likely to benefit from intensive therapies is needed. Here, we review currently available objective measures to define older adults with AML who are ineligible for intensive chemotherapy, and discuss promising investigational approaches. PMID:26697412

    Acute alcohol exposure has been shown to produce differential motor impairments between aged and adult rats and between adolescent and adult rats. However, the effects of acute alcohol exposure among adolescent, adult, and aged rats have yet to be systematically investigated within the same project using a dose-dependent analysis. We sought to determine the age- and dose-dependent effects of acute alcohol exposure on gross and coordinated motor performance across the rodent lifespan. Adolescent (PD 30), adult (PD 70), and aged (approximately 18 months) male Sprague-Dawley rats were tested on 3 separate motor tasks: aerial righting reflex (ARR), accelerating rotarod (RR), and loss of righting reflex (LORR). In a separate group of animals, blood ethanol concentrations (BEC) were determined at multiple time points following a 3.0 g/kg ethanol injection. Behavioral tests were conducted with a Latin square repeated-measures design in which all animals received the following doses: 1.0 g/kg or 2.0 g/kg alcohol or saline over 3 separate sessions via intraperitoneal (i.p.) injection. During testing, motor impairments were assessed on the RR 10 min post-injection and on ARR 20 min post-injection. Aged animals spent significantly less time on the RR when administered 1.0 g/kg alcohol compared to adult rats. In addition, motor performance impairments significantly increased with age after 2.0 g/kg alcohol administration. On the ARR test, aged rats were more sensitive to the effects of 1.0 g/kg and 2.0 g/kg alcohol compared to adolescents and adults. Seven days after the last testing session, animals were given 3.0 g/kg alcohol and LORR was examined. During LORR, aged animals slept longer compared to adult and adolescent rats. This effect cannot be explained solely by BEC levels in aged rats. The present study suggests that acute alcohol exposure produces greater motor impairments in older rats when compared to adolescent and adult rats and begins to establish a

    Background and Purpose: The efficacy of retigabine (RGB), a positive allosteric modulator of K+ channels indicated for adjunct treatment of partial seizures, was studied in two adult models of kainic acid (KA)-induced status epilepticus to determine it’s toleratbility. Methods: Retigabine was administered systemiclly at high (5 mg/kg) and low (1–2 mg/kg) doses either 30 min prior to or 2 hr after KA-induced status epilepticus. High (1 µg/µL) and low (0.25 µg/µL) concentrations of RGB were also delivered by intrahippocampal microinjection in the presence of KA. Results: Dose-dependent effects of RGB were observed with both models. Lower doses increased seizure behavior latency and reduced the number of single spikes and synchronized burst events in the electroencephalogram (EEG). Higher doses worsened seizure behavior, produced severe ataxia, and increased spiking activity. Animals treated with RGB that were resistant to seizures did not exhibit significant injury or loss in GluR1 expression; however if stage 5–6 seizures were reached, typical hippocampal injury and depletion of GluR1 subunit protein in vulernable pyramidal fields occurred. Conclusions: RGB was neuroprotective only if seizures were significantly attenuated. GluR1 was simultaneously suppressed in the resistant granule cell layer in presence of RGB which may weaken excitatory transmission. Biphasic effects observed herein suggest that the human dosage must be carefully scrutinized to produce the optimal clinical response. PMID:26819936

    In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ) hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

Acute colitis has multiple causes with varying degrees of severity. Analysis of the extent of colonic involvement, presence of specific MDCT imaging features and associated signs should help radiologist narrow the diagnosis. Integrating the results of clinical examination and biological tests is mandatory, and in case of ambiguous or nonspecific MDCT findings, endoscopy and colon biopsy should always be considered for a definite diagnosis.

    The acute effect of whole-body vibration (WBV) training may enhance muscular performance via neural potentiation of the stretch reflex. The purpose of this study was to investigate if acute WBV exposure affects the stretch induced knee jerk reflex [onset latency and electromechanical delay (EMD)] and the isokinetic knee extensor peak torque performance. Twenty-two subjects were randomly assigned to the intervention or control group. The intervention group received WBV in a semi-squat position at 30° knee flexion with an amplitude of 0.69 mm, frequency of 45 Hz, and peak acceleration of 27.6 m/s2 for 3 minutes. The control group underwent the same semii-squatting position statically without exposure of WBV. Two-way mixed repeated measures analysis of variance revealed no significant group effects differences on reflex latency of rectus femoris (RF) and vastus lateralis (VL; p = 0.934 and 0.935, respectively) EMD of RF and VL (p = 0.474 and 0.551, respectively) and peak torque production (p = 0.483) measured before and after the WBV. The results of this study indicate that a single session of WBV exposure has no potentiation effect on the stretch induced reflex and peak torque performance in healthy young adults. Key Points There is no acute potentiation of stretch reflex right after whole body vibration. Acute whole body vibration does not improve mus-cle peak torque performance in healthy young adults.

    The objective was to determine if acute alcohol consumption is associated with differences in injury pattern among young adult patients with traumatic injuries presenting to emergency medical services (EMS). A cross-sectional, retrospective review of prehospital patient care reports (PCRs) was conducted evaluating injured patients who presented to a collegiate EMS agency from January 1, 2011 to December 31, 2012. Included patients were age 18-24 y and sustained an injury within the previous 24 h. PCRs were reviewed independently by two abstractors to determine if the patient was documented to have acutely consumed alcohol proximate to his/her injury. Primary and secondary sites of regional body injury were recorded. Injury severity was recorded using the Revised Trauma Score (RTS). The association between primary injury site and acute alcohol use was assessed using a chi-square test. Multiple logistic regression was used to control for sex in predicting injury type. Of 440 injured patients, 135 (30.6%) had documented alcohol use prior to injury. Acute alcohol consumption altered the overall pattern of regional injury (p < 0.001). Alcohol users were more likely to present with injury secondary to assault, fall/trip, and unknown mechanism of injury (p < 0.001, all comparisons). RTS scores were statistically lower in the alcohol group (p < 0.001), although the clinical significance of this is unclear. Controlling for sex, acute alcohol consumption predicted increased risk of head/neck injury 5.59-fold (p < 0.001). Acute alcohol use in collegiate EMS patients appears to alter injury patterns in young adults and increases risk of head/neck injury. EMS providers in similar agencies should consider these trends when assessing and treating injured college-aged patients. PMID:27002348

    Eosinophils have been traditionally perceived as largely end-stage, cytotoxic effector cells. Recent studies have profoundly altered this simplistic view of eosinophils and their function. New insights into the molecular basis of development, trafficking and degranulation of eosinophils have provided a better understanding of the role of these cells in promoting homeostasis through their immunomodulatory functions. Likewise, recent developments have generated a more sophisticated view of how eosinophils contribute to the pathogenesis of disease, including asthma and primary hypereosinophilic syndromes, and also a more complete appreciation of their activities in parasitic infection.

    Eosinophilic granuloma occurs almost exclusively in the diaphysis or metaphysis, when tubular bones are affected. The investigators present an extremely rare case of eosinophilic granuloma arising at the epiphysis of the femoral head in an 8-year-old boy. Plain radiographs and computed tomography showed a well-circumscribed radiolucent lesion, suggesting chondroblastoma or Brodie's abscess. However, the findings on magnetic resonance images were different from typical features of chondroblastoma or Brodie's abscess. The lesion was curetted. Histological diagnosis was eosinophilic granuloma. Differential diagnoses of a radiolucent lesion at the epiphysis in a child should include, though quite rare, eosinophilic granuloma.

    Eosinophilic inflammation is a characteristic feature of asthma. Integrins are highly versatile cellular receptors that regulate extravasation of eosinophils from the postcapillary segment of the bronchial circulation to the airway wall and airspace. Such movement into the asthmatic lung is described as a sequential, multistep paradigm, whereby integrins on circulating eosinophils become activated, eosinophils tether in flow and roll on bronchial endothelial cells, integrins on rolling eosinophils become further activated as a result of exposure to cytokines, eosinophils arrest firmly to adhesive ligands on activated endothelium, and eosinophils transmigrate to the airway in response to chemoattractants. Eosinophils express seven integrin heterodimeric adhesion molecules: alpha4beta1 (CD49d/29), alpha6beta1 (CD49f/29), alphaMbeta2 (CD11b/18), alphaLbeta2 (CD11a/18), alphaXbeta2 (CD11c/18), alphaDbeta2 (CD11d/18), and alpha4beta7 (CD49d/beta7). The role of these integrins in eosinophil recruitment has been elucidated by major advances in the understanding of integrin structure, integrin function, and modulators of integrins. Such findings have been facilitated by cellular experiments of eosinophils in vitro, studies of allergic asthma in humans and animal models in vivo, and crystal structures of integrins. Here, we elaborate on how integrins cooperate to mediate eosinophil movement to the asthmatic airway. Antagonists that target integrins or the effectors that regulate integrins of eosinophils represent potentially promising therapies in the treatment of asthma. PMID:17906117

    We have previously demonstrated that aging reduces the compensatory vasodilator response during hypoxic exercise due to blunted nitric oxide (NO) signaling. Recent evidence suggests that NO bioavailability can be augmented by dietary nitrate through the nitrate-nitrite pathway. Thus we tested the hypothesis that acute dietary nitrate supplementation increases the compensatory vasodilator response to hypoxic exercise, particularly in older adults. Thirteen young (25 ± 1 yr) and 12 older (64 ± 2 yr) adults performed rhythmic forearm exercise at 20% of maximum voluntary contraction during normoxia and hypoxia (∼80% O2 saturation); both before (control) and 3 h after beetroot juice (BR) consumption. Forearm vascular conductance (FVC; ml·min(-1)·100 mmHg(-1)) was calculated from forearm blood flow (ml/min) and blood pressure (mmHg). Compensatory vasodilation was defined as the relative increase in FVC due to hypoxic exercise (i.e., % increase compared with respective normoxic exercise trial). Plasma nitrite was determined from venous blood samples obtained before the control trials and each of the exercise trials (normoxia and hypoxia) after BR. Consumption of BR increased plasma nitrite in both young and older adults (P < 0.001). During the control condition, the compensatory vasodilator response to hypoxic exercise was attenuated in older compared with young adults (3.8 ± 1.7% vs. 14.2 ± 1.2%, P < 0.001). Following BR consumption, compensatory vasodilation did not change in young (13.7 ± 3.3%, P = 0.81) adults but was substantially augmented in older adults (11.4 ± 2.1%, P < 0.01). Our data suggest that acute dietary nitrate supplementation increases the compensatory vasodilator response to hypoxic exercise in older but not young adults.

    Objective: Mepolizumab is a humanized IgG1 monoclonal antibody that blocks human IL-5 from binding to the IL-5 receptor, which is mainly expressed on eosinophils. Eosinophils are key cells in the inflammatory cascade of various diseases, including asthma. This study investigated the pharmacokinetic (PK)/pharmacodynamic (PD) relationship between exposure of mepolizumab subcutaneous (SC) administration and blood eosinophil reduction compared with intravenous (IV) administration in adult subjects with asthma. Methods: In this multi-center, randomized, open-label, parallel-group, repeat-dose study, 70 adult subjects received one of four possible treatment regimens: mepolizumab 12.5, 125, or 250 mg SC or 75 mg IV. In addition to analyzing the dose and PK/PD relationship, absolute bioavailability, safety, tolerability, and incidence of anti-mepolizumab antibodies were evaluated. Results: Blood eosinophil levels decreased in a dose-dependent manner with the lowest (12.5 mg) dose clearly differentiating from the other doses. A non-linear inhibition Imax model based on blood eosinophil levels at week 12 identified that the SC doses providing 50% and 90% of maximal blood eosinophil inhibition were 11 mg (95% confidence interval (CI): 5.19 – 16.85) and 99 mg (95% CI: 47 – 152), respectively. The route of administration did not affect the exposure-response relationship. The estimated mepolizumab SC absolute bioavailability (arm) was 74% (90% CI: 54 – 102%). The safety profile of mepolizumab was favorable. Conclusions: A dose-dependent reduction in blood eosinophils across all mepolizumab doses investigated was observed. The subcutaneous absolute bioavailability was 74%. The route of administration did not affect the mepolizumab exposure eosinophil response relationship. PMID:26445140

    Eosinophilic otitis media (EOM) is a relatively rare, intractable, middle ear disease with extremely viscous mucoid effusion containing eosinophils. EOM is associated with adult bronchial asthma and nasal allergies. Conventional treatments for otitis media with effusion (OME) or for chronic otitis media (COM), like tympanoplasty or mastoidectomy, when performed for the treatment of EOM, can induce severe complications such as deafness. Therefore, it should be differentiated from the usual type of OME or COM. To our knowledge, the clinical and imaging findings of EOM of temporal bone are not well-known to radiologists. We report here the CT and MRI findings of two EOM cases and review the clinical and histopathologic findings of this recently described disease entity. PMID:22563277

    The aim of the present study is to describe the clinical and epidemiological characteristics, complications and outcome of patients with haemophilia and acute head injury (AHI) at the emergency department (ED), and develop a protocol to prevent early and late complications. This is a retrospective cohort study including all patients with haemophilia and AHI admitted to the ED. We identified 26 patients with AHI. A computed tomography scan was carried out on all patients at admission, and again on two patients (with neurosurgical complications) 48 h later. The discharge diagnosis was as follows: 3.8% subdural haematoma, 3.8% cerebellar epidural haematoma and 92.3% uncomplicated AHI. We propose the following protocol: a computed tomography scan upon arrival and another within 48 h post-AHI, unless there is an absence of clinical symptoms. In addition, all patients must self-administer a clotting factor as soon as possible and be observed in the ED for at least 48 h.

    Eosinophilic esophagitis is characterized by destructive responses of the immune system to environmental allergens, including food, on the human esophagus. EoE is now reported as a major cause of upper gastrointestinal morbidity in children and adults and the incidence is reported to be on the increase. It is known that EoE has a high degree of heritability, with a majority of the phenotypic variation believed to be genetic in origin as shown by genetic epidemiology studies of twins and families. Prior to 2010, there were no known genetic risk factors for the disease. Three GWAS have since been published identifying 5 loci which influence risk for EoE in both children and adults. The information gained from GWAS has been of value in elucidating the pathways involved, such as IL4/STAT6, and more unexpected pathways such as epithelial apical transport and wound healing. We will review the results of the EoE GWAS and the known associated genes, concluding with a discussion of some future directions for genetic studies in EoE. PMID:26552769

  18. Staphylococcus aureus: is it a pathogen of acute bacterial sinusitis in children and adults?

    Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are the etiologic agents of acute bacterial sinusitis (ABS). Staphylococcus aureus has been an uncommon cause of ABS despite its frequent occupancy within the anterior nares. A quantitative culture of a maxillary sinus aspirate is the gold standard for determining etiology of ABS. Cultures of the middle meatus cannot be used as a surrogate for a maxillary sinus aspirate in children with ABS, although they may be used in adults if interpretation is confined to usual sinus pathogens. Recent studies highlighting S. aureus as a major pathogen in ABS should be interpreted cautiously. Most isolates in recent pediatric studies were derived from cultures of the middle meatus. The range of reported results for the incidence of S. aureus as a cause of ABS in adults is similar to the results reported for staphylococcal colonization of the middle meatus in healthy adults.

    This study examined differential responding of juvenile, adolescent, and adult rats after intoxication from an acute alcohol challenge. Experiment I generated blood ethanol curves for subjects 25, 35, or 110 days postnatal, after doses of 2.0 or 4.0 g/kg, assessing elimination rates and time of drug clearance. Experiment 2 compared ethanol's initial hypothermic and delayed hyperthermic effect across age by 48-hr temperature measurement with telemetry. At clearance or 24 hr after alcohol exposure, Experiment 3 tested subjects for changes in acoustic startle reactivity and ultrasonic vocalization (USV). Younger rats showed an absent or reduced tendency for residual hyperthermia, and adults showed alterations in USV observed as aftereffects of intoxication, despite greater initial blood alcohol levels and ethanol hypothermia in the former. The lesser ethanol hangover effects in weanlings and adolescents may be due in part to faster ethanol elimination at these ages compared with adults.

    Emerging evidence supports impaired epithelial barrier function as the key initial event in the development of eosinophilic esophagitis (EoE) and other allergic diseases. Symptom resolution, histologic remission, and prevention of both disease and treatment-related complications are the goals of treatment. Successful dietary treatments include elemental, empirical elimination and allergy test directed diets. Dietary therapy with exclusive elemental diet offers the best response. Cow's milk, wheat, egg, soy, peanut/tree nut, and fish/shellfish are the 6 food antigens most likely to induce esophageal inflammation.

    The gastrointestinal (GI) tract provides an intriguing organ for considering the eosinophil's role in health and disease. The normal GI tract, except for the esophagus, is populated by eosinophils that are present throughout the mucosa, raising the possibility that eosinophils participate in innate mechanisms of defense. However, data from clinical studies associates increased numbers of eosinophils with inflammatory GI diseases, prompting concerns that eosinophils may have a deleterious effect on the gut. We present clinical features of 4 disease processes that have been associated with eosinophilia and suggest areas requiring investigation as to their clinical significance and scientific relevance.

    Background and Objectives There is an emerging evidence base for the use of music therapy in the treatment of severe mental illness. Whilst different models of music therapy have been developed in mental health care, none have specifically accounted for the features and context of acute in-patient settings. This review aimed to identify how music therapy is provided for acute adult psychiatric in-patients and what outcomes have been reported. Review Methods A systematic review using medical, psychological and music therapy databases. Papers describing music therapy with acute adult psychiatric in-patients were included. Analysis utilised narrative synthesis. Results 98 papers were identified, of which 35 reported research findings. Open group work and active music making for nonverbal expression alongside verbal reflection was emphasised. Aims were engagement, communication and interpersonal relationships focusing upon immediate areas of need rather than longer term insight. The short stay, patient diversity and institutional structure influenced delivery and resulted in a focus on single sessions, high session frequency, more therapist direction, flexible use of musical activities, predictable musical structures, and clear realistic goals. Outcome studies suggested effectiveness in addressing a range of symptoms, but were limited by methodological shortcomings and small sample sizes. Studies with significant positive effects all used active musical participation with a degree of structure and were delivered in four or more sessions. Conclusions No single clearly defined model exists for music therapy with adults in acute psychiatric in-patient settings, and described models are not conclusive. Greater frequency of therapy, active structured music making with verbal discussion, consistency of contact and boundaries, an emphasis on building a therapeutic relationship and building patient resources may be of particular importance.

    Age-related developmental differences in sensitivity to the acute effects of alcohol may play an important role in the development of alcoholism. The present study was designed to evaluate the acute effects of alcohol on cortical electroencephalogram (EEG) in adolescent (P36) and adult (P78) Wistar rats. Five minutes of EEG was recorded after administration of 0, 0.75 or 1.5 g/kg alcohol. The righting reflex was performed to measure the sedative effects of alcohol (3.5 g/kg) and total sleeping time for each rat. Our results showed that alcohol (1.5 g/kg) increased power in the 1–2 Hz band and decreased the power in the 32–50 Hz band in the parietal cortical region of adolescent rats. Alcohol (1.5 g/kg) also increased stability of the EEG power in the slow-wave frequency bands (2–4 Hz, 4–6 Hz, and 6–8 Hz) of adolescent rats. In the frontal cortex of adult rats, but not in adolescent rats, alcohol (1.5 or 0.75 g/kg) decreased the power in the 16–32 Hz frequency band. Alcohol (1.5 g/kg) differentially increased power in a multiple of slow-wave frequency bands (2–4 Hz and 4–6 Hz) in the parietal cortex of adult rats as compared to adolescent rats. Adolescent rats were shown significantly shorter sleeping time and higher blood alcohol levels after regaining reflex than adult rats. Our results provide additional evidence of age-related differences in the effects of acute alcohol on cortical EEG, sedation and tolerance. PMID:18191821

    The pattern-recognition receptor (PRR) family includes Toll-like receptors (TLRs), nucleotide-binding oligomerization domain (NOD) -like receptors (NLRs), RIG-I-like receptors (RLRs), C-type lectin receptors (CLRs) and the receptor for advanced glycation end products (RAGE). They recognize various microbial signatures or host-derived danger signals and trigger an immune response. Eosinophils are multifunctional leucocytes involved in the pathogenesis of several inflammatory processes, including parasitic helminth infection, allergic diseases, tissue injury and tumour immunity. Human eosinophils express several PRRs, including TLR1–5, TLR7, TLR9, NOD1, NOD2, Dectin-1 and RAGE. Receptor stimulation induces survival, oxidative burst, activation of the adhesion system and release of cytokines (interleukin-1β, interleukin-6, tumour necrosis factor-α and granulocyte–macrophage colony-stimulating factor), chemokines (interleukin-8 and growth-related oncogene-α) and cytotoxic granule proteins (eosinophil cationic protein, eosinophil-derived neurotoxin, eosinophil peroxidase and major basic protein). It is also evident that eosinophils play an immunomodulatory role by interacting with surrounding cells. The presence of a broad range of PRRs in eosinophils indicates that they are not only involved in defence against parasitic helminths, but also against bacteria, viruses and fungi. From a clinical perspective, eosinophilic PRRs seem to be involved in both allergic and malignant diseases by causing exacerbations and affecting tumour growth, respectively. PMID:22242941

    To analyze the role of eosinophils in alveolitis due to immunological interstitial lung disorders, 568 bronchoalveolar lavage (BAL) from 537 patients affected by 13 types of interstitial lung disease involving immunologic mechanisms were considered. An arbitrary cut-off of 4% of eosinophils in BAL was assumed. In five (idiopathic pulmonary fibrosis (IPF), allergic bronchopulmonary aspergillosis (ABPA), amiodarone-induced pneumonitis (AIP), chronic eosinophilic pneumonia (CEP), Churg-Strauss syndrome (CSS)) out of the thirteen groups we took into consideration, the level of eosinophils was greater than 4%. In CEP and CSS in particular, the arbitrary cut-off of 4% was greatly exceeded (28.9% +/- 27.4, p less than 0.01 and 33.6% +/- 14.5, p less than 0.01, respectively). In the same two groups the increase of eosinophils in BAL was isolated with a direct correlation to the number of eosinophils in blood. By contrast, the increase of eosinophils in BAL of IPF, AIP and ABPA was of lesser extent (4.7% +/- 5.7 p less than 0.01, 5.0% +/- 3.0 p less than 0.01 and 6.1% +/- 10.4 p less than 0.01, respectively) and was accompanied by an increase of neutrophils in IPF, of lymphocytes in AIP and both in ABPA. These patterns are generally defined as "mixed alveolitis." On the basis of these data we conclude that the term "eosinophilic alveolitis" should be reserved for CEP and CSS.

    2014-01-01

    Eosinophilic esophagitis (EoE) is an emerging disease characterized by esophageal eosinophilia (>15eos/hpf), lack of responsiveness to acid-suppressive medication and is managed by allergen elimination and anti-allergy therapy. Although the pathophysiology of EoE is currently unsubstantiated, evidence implicates food and aeroallergen hypersensitivity in genetically predisposed individuals as contributory factors. Genome-wide expression analyses have isolated a remarkably conserved gene-expression profile irrespective of age and gender, suggesting a genetic contribution. EoE has characteristics of mainly TH2 type immune responses but also some TH1 cytokines, which appear to strongly contribute to tissue fibrosis, with esophageal epithelial cells providing a hospitable environment for this inflammatory process. Eosinophil-degranulation products appear to play a central role in tissue remodeling in EoE. This remodeling and dysregulation predisposes to fibrosis. Mast-cell-derived molecules such as histamine may have an effect on enteric nerves and may also act in concert with transforming growth factor-β to interfere with esophageal musculature. Additionally, the esophageal epithelium may facilitate the inflammatory process under pathogenic contexts such as in EoE. This article aims to discuss the contributory factors in the pathophysiology of EoE. PMID:24910846

    Immunoglobulin heavy chain gene (IgH gene) rearrangements are found in the majority of cases of B-lineage acute lymphoblastic leukaemia (ALL). We have examined bone marrow samples taken at presentation or relapse from 109 patients (79 adults and 30 children) and have performed sequence analysis of the complementarity determining region 3 (CDR3) on 65 alleles from 54 patients. We aimed to define immunoglobulin heavy chain (IgH) variable segment family use and investigate biological and structural features of the B cell in adult and childhood ALL. Using the FR1 fingerprinting method, a rearranged band was identified in 70 (89%) of 79 adult ALL and in 29 (97%) of 30 childhood ALL. This study found no preferential use or selection of IgH VH genes and no statistically significant structural differences between normal and leukaemic B cells in either adult and childhood ALL. An equal proportion of amplifiable cases of adult and childhood ALL uses more than one VH family gene (24/70, 34%, and 8/29, 27.5%, respectively). There were no significant differences in the structure or size of the CDR3 region and the variable (V) or joining (J) segment use in ALL patients compared to normal B cells. We observed that the N2 region was shorter than N1 in children whereas the opposite was observed in adults (not statistically significant). The J4 segment was a more common rearrangement in children than in adults, and in both groups J4 was more frequently associated with multiple D segment VDJ rearrangements. An increase in VH6 use in leukaemic alleles compared to normal B lymphocytes (2%) was observed but it was not statistically significant in our group of patients. Amongst children and adults, in-frame CDR3 junctions occurred in 78% and 64% of rearranged alleles, respectively, compared to 75% of in-frame sequences reported by others to occur among normal B cells.

    Eosinophilic gastroenteritis (EGE) is a rare condition characterized by eosinophilic infiltration of the gastrointestinal tract. Depending on the dominant layer of infiltration it is classified into three types namely, mucosal, muscularis and subserosal. The most uncommon variant is the subserosal type characterized by primarily subserosal disease, eosinophilic ascites and peripheral hypereosinophilia. The clinical features are non-specific with history of atopic predisposition and allergy. Endoscopic biopsy is frequently non-diagnostic due to an uninvolved gastrointestinal mucosa rendering its diagnosis a challenge. The mainstay of diagnosis is peripheral hypereosinophilia and eosinophil-rich ascitic fluid on diagnostic paracentesis. Oral steroid therapy is usually the first line of treatment with dramatic response. Due to a propensity for relapse, steroid-sparing therapy should be considered for relapses of EGE. We report a case of subserosal EGE with diagnostic clinical features and treatment response and review the current strategy in the management of eosinophilic ascites. PMID:27721930

    A 42-year-old man with a history of childhood asthma presented with a 2-week history of watery diarrhoea and marked peripheral eosinophilia in the setting of recent use of cephalexin. His colonoscopy revealed patchy colitis. Biopsies were consistent with eosinophilic colitis. Two months later he received a course of amoxicillin resulting in recurrence of peripheral eosinophilia. Given the time-frame of β-lactam administration to symptom onset and elimination of all other precipitating causes, he was diagnosed with β-lactam-associated eosinophilic colitis. The patient's symptoms resolved and peripheral eosinophil count decreased with no specific treatment. Eosinophilic colitis is a rare heterogeneous condition, the pathogenesis of which is likely to be an interplay between environmental and genetic factors. It can be secondary to a helminthic infection or a drug reaction and has been associated with ulcerative colitis. If secondary causes of eosinophilic colitis have been excluded, the mainstay of treatment is with corticosteroids. PMID:26106168

    Adults with relapsed or refractory B-cell acute lymphoblastic leukemia have a dismal prognosis with a short median overall survival that can be measured in months. Because most patients will have chemotherapy-resistant disease, allogeneic hematopoietic stem cell transplantation remains the only potentially curative treatment. Despite advances in current management, patients continue to have poor outcomes and lack of durable responses. Thus, new therapies with alternative modes of actions are currently being investigated. Blinatumomab is a novel bispecific T-cell engager that simultaneously binds CD3-positive cytotoxic T-cells and CD19-positive B-cells, resulting in selective lysis of tumor cells. It has shown promising results in patients with relapsed or refractory acute lymphoblastic leukemia or those achieving hematologic response with persistent minimum residual disease. Future clinical trials will answer questions regarding its optimal place in the treatment paradigm. Dose-limiting toxicities include immunological toxicities and cytokine release syndrome. However, most patients tolerate the therapy relatively well. This review will focus on the pharmacology, clinical efficacy, and safety of blinatumomab in the treatment of adult B-cell acute lymphoblastic leukemia while highlighting its unique drug warnings and toxicity management.

    Introduction: Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxication may be fatal due to perforation or tracheal necrosis. Enteral nutrition is a nutritional method when nutritional substances are administered through specially designed tubing placed through the nose or percutaneously, directly into the GIT. Aim: The aim of this study is to describe the methods of artificial nutrition in patients with acute corrosive intoxications and the importance of nutritional support in the treatment of these intoxications. Discussion: Nutrition in the treatment of acute corrosive intoxications is one of the most important therapeutic processes that largely contribute to faster recovery of the post-corrosive injuries of upper GIT, stabilization of biologic, immunologic and metabolic parameters, and reduction of length of stay in hospital Aim of the treatment of acute corrosive intoxications is to prevent perforation and progressive fibrosis, and esophageal and gastric stenosis. There are different and often conflicting positions, on the conservative treatment of acute corrosive intoxications in adults. Such treatment mainly consists of anti-secretory treatment, antibiotics and intensive hyper-alimentation, aiming to prevent late post-corrosive intoxications. Conclusion: It is considered that nutritional support plays a major role in maintenance of metabolic processes and prevention of severe metabolic complications that could additionally aggravate the condition and impair the treatment.

    This study was aimed to investigate the expression and clinical significance of CDX1, CDX2 and CDX4 genes in acute lymphocytic leukemia (ALL). Expressions of CDX1, CDX2, and CDX4 in 51 adult acute lymphocytic leukemia patients and 14 healthy subjects were detected by reverse transcription polymerase chain reaction (RT-PCR). The results indicated that CDX1, CDX2 and CDX4 were not expressed in 14 healthy persons and 15 CR ALL patients, the positive expression rate of CDX2 gene in de novo ALL patients was 60.8%, while it obviously decreased in patients with complete remission (CR) (p < 0.05); the expression of CDX2 was increased again in relapsed patients (81.8%). When the expression of CDX2 was analyzed in different risk groups of ALL patients, the CDX2 expression rate in high risk (HR) patients was 91.7%, and that in the standard risk (SR) group was 45.7%. Furthermore, analyses of CDX1 and CDX4 expression in series of ALL samples did not show the expression of these genes. In patients with adult ALL at diagnosis and relapse, the CR rate of patients with CDX2 positive expression was lower than that of patients with CDX2 negative expression (p < 0.05). The median survival time in CDX2 positive expression patients was shorter than that in negative expression patient. It is concluded that expression of CDX2 may correlated with pathogenesis and relapse of adult ALL, but the expression of CDX1 and CDX4 don' t associated with pathogenesis and relapse of adult ALL; the CR rate and prognosis of patients with CDX2 positive expression is lower and poor. The expression of CDX2 may be used as a marker for occurrence, relapse and poor prognosis of adult ALL patients.

    Objectives To identify the viral aetiology in adult patients with severe acute respiratory infection (SARI) admitted to sentinel surveillance institutions in Bogotá in 2012. Design A cross-sectional study was conducted in which microarray molecular techniques for viral identification were used on nasopharyngeal samples of adult patients submitted to the surveillance system, and further descriptions of clinical features and relevant clinical outcomes, such as mortality, need for critical care, use of mechanical ventilation and hospital stay, were obtained. Setting Respiratory infections requiring hospital admission in surveillance centres in Bogotá, Colombia. Participants Ninety-one adult patients with acute respiratory infection (55% were female). Measurements Viral identification, intensive care unit admission, hospital stay, and mortality. Results Viral identification was achieved for 63 patients (69.2%). Comorbidity was frequently identified and mainly involved chronic pulmonary disease or pregnancy. Influenza, Bocavirus and Adenovirus were identified in 30.8%, 28.6% and 18.7% of the cases, respectively. Admission to the intensive care unit occurred in 42.9% of the cases, while mechanical ventilation was required for 36.3%. The average hospital stay was 9.9 days, and mortality was 15.4%. Antibiotics were empirically used in 90.1% of patients. Conclusions The prevalence of viral aetiology of SARI in this study was high, with adverse clinical outcomes, intensive care requirements and high mortality. PMID:26576054

    Summary The development of the living acute brain slice preparation for analyzing synaptic function roughly a half century ago was a pivotal achievement that greatly influenced the landscape of modern neuroscience. Indeed, many neuroscientists regard brain slices as the gold-standard model system for detailed cellular, molecular, and circuitry level analysis and perturbation of neuronal function. A critical limitation of this model system is the difficulty in preparing slices from adult and aging animals, and over the past several decades few substantial methodological improvements have emerged to facilitate patch clamp analysis in the mature adult stage. In this chapter we describe a robust and practical protocol for preparing brain slices from mature adult mice that are suitable for patch clamp analysis. This method reduces swelling and damage in superficial layers of the slices and improves the success rate for targeted patch clamp recordings, including recordings from fluorescently labeled populations in slices derived from transgenic mice. This adult brain slice method is suitable for diverse experimental applications, including both monitoring and manipulating neuronal activity with genetically encoded calcium indicators and optogenetic actuators, respectively. We describe the application of this adult brain slice platform and associated methods for screening kinetic properties of Channelrhodopsin (ChR) variants expressed in genetically-defined neuronal subtypes.

    Adolescents and young adults (AYAs, ages 15 to 40 years) with cancer have not experienced survival improvements to the same extent as younger and older patients. We compared changes in survival after myeloablative allogeneic hematopoietic cell transplantation (HCT) for acute lymphoblastic leukemia (ALL) among children (n = 981), AYAs (n = 1218), and older adults (n = 469) who underwent transplantation over 3 time periods: 1990 to 1995, 1996 to 2001, and 2002 to 2007. Five-year survival varied inversely with age group. Survival improved over time in AYAs and paralleled that seen in children; however, overall survival did not change over time for older adults. Survival improvements were primarily related to lower rates of early treatment-related mortality in the most recent era. For all cohorts, relapse rates did not change over time. A subset of 222 AYAs between the ages of 15 and 25 at 46 pediatric or 49 adult centers were also analyzed to describe differences by center type. In this subgroup, there were differences in transplantation practices among pediatric and adult centers, although HCT outcomes did not differ by center type. Survival for AYAs undergoing myeloablative allogeneic HCT for ALL improved at a similar rate as survival for children. PMID:24607554

    Cancer progresses with a change in the structure of the gene network in normal cells. We define a measure of organizational hierarchy in gene networks of affected cells in adult acute myeloid leukemia (AML) patients. With a retrospective cohort analysis based on the gene expression profiles of 116 acute myeloid leukemia patients, we find that the likelihood of future cancer relapse and the level of clinical risk are directly correlated with the level of organization in the cancer related gene network. We also explore the variation of the level of organization in the gene network with cancer progression. We find that this variation is non-monotonic, which implies the fitness landscape in the evolution of AML cancer cells is nontrivial. We further find that the hierarchy in gene expression at the time of diagnosis may be a useful biomarker in AML prognosis. PMID:25685944

    Bench press exercise, which involves repetitive lifting of weights to full arm extension while lying supine on a narrow bench, has been associated with complications ranging in acuity from simple pectoral muscle strain, to aortic and coronary artery dissection. A 39-year-old man, physically fit and previously asymptomatic, presented with acute chest pain following bench press exercise. Diagnostic evaluation led to the discovery of critical multivessel coronary occlusive disease, and subsequently, highly elevated levels of lipoprotein (a). Judicious use of ancillary testing may identify the presence of “high-risk” conditions in a seemingly “low-risk” patient. Emergency department evaluation of the young adult with acute chest pain must take into consideration an extended spectrum of potential etiologies, so as to best guide appropriate management.

    In eosinophilic esophagitis (EoE), remodeling changes are manifest histologically in both the epithelium as well as in the subepithelium where lamina propria (LP) fibrosis, expansion of the muscularis propria and increased vascularity occur. The major clinical symptoms and complications of EoE are largely consequences of esophageal remodeling. Important mediators of the process include IL-5, IL-13, TGFβ1, mast cells, fibroblasts and eosinophils. Methods to detect remodeling effects include upper endoscopy, histopathology, barium esophagram, endoscopic ultrasonography, esophageal manometry, and functional luminal imaging. These modalities provide evidence of organ dysfunction that include focal and diffuse esophageal strictures, expansion of the mucosa and subepithelium, esophageal motor abnormalities and reduced esophageal distensibility. Complications of food impaction and perforations of the esophageal wall have been associated with reduction in esophageal caliber and increased esophageal mural stiffness. The therapeutic benefits of topical corticosteroids and elimination diet therapy in resolving mucosal eosinophilic inflammation of the esophagus are evident. Available therapies, however, have demonstrated variable ability to reverse existing remodeling changes of the esophagus. Systemic therapies that include novel, targeted biologic agents have the potential of addressing subepithelial remodeling. Esophageal dilation remains a useful, adjunctive therapeutic maneuver in symptomatic adults with esophageal stricture. As novel treatments emerge, it is essential that therapeutic endpoints account for the fundamental contributions of esophageal remodeling to overall disease activity. PMID:24813517

    Accessing timely acute medical care is a challenge for older adults. This article describes an innovative healthcare model that uses high-intensity telemedicine services to provide rapid acute care for older adults without requiring them to leave their senior living community (SLC) residences. This program, based in a primary care geriatrics practice that cares for SLC residents, is designed to offer acute care through telemedicine for complaints that are felt to need attention before the next available outpatient visit but not to require emergency department (ED) resources. This option gives residents access to care in their residence. Measures used to evaluate the program include successful completion of telemedicine visits, satisfaction of residents and caregivers with telemedicine care, and site of care that would have been recommended had telemedicine been unavailable. During the first 2 years of the program's operation, 281 of 301 requested telemedicine visits were completed successfully. Twelve residents were sent to an ED for care after the telemedicine visit. Ninety-four percent of residents reported being satisfied or very satisfied with telemedicine care. Had telemedicine not been available, residents would have been sent to an ED (48.1%) or urgent care center (27.0%) or been scheduled for an outpatient visit (24.4%). The project demonstrated that high-intensity telemedicine services for acute illnesses are feasible and acceptable and can provide definitive care without requiring ED or urgent care use. Continuation of the program will require evaluation demonstrating equal or better resident-level outcomes and the development of sustainable business models.

    The traditional paradigm of eosinophils as end-stage damaging cells has mainly relied on their release of cytotoxic proteins. Cytokine-induced cell survival and secretion of granular contents from tissue-dwelling eosinophil are thought to be important mechanisms for eosinophilic inflammatory disorders, although the occurrence of cytolysis and its products (i.e., free extracellular granules) has been observed in affected lesions. Recent evidence indicates that activated eosinophils can exhibit a non-apoptotic cell death pathway, namely extracellular trap cell death (ETosis) that mediates the eosinophil cytolytic degranulation. Here, we discuss the current concept of eosinophil ETosis which provides a new look at eosinophilic inflammation. Lessons from eosinophilic chronic rhinosinusitis revealed that ETosis-derived DNA traps, composed of stable web-like chromatin, contribute to the properties of highly viscous eosinophilic mucin and impairments in its clearance. Intact granules entrapped in DNA traps are causing long-lasting inflammation but also might have immunoregulatory roles. Eosinophils possess a way to have post-postmortem impacts on innate immunity, local immune response, sterile inflammation, and tissue damage. PMID:27393701

    We report 2 adult cases where the diagnosis of acute plastic bowing of the forearm was either delayed or missed. In a 21-year-old man, ulnar bowing was missed and fixation was not performed because the patient had no limitation to his range of movement or pain. In a 24-year-old woman, the presentation of bowing in both the ulna and radius was delayed and corrective osteotomy was necessary for restoration of full range of movement. Prompt diagnosis enables manual reposition for easy restoration of full range of movement. PMID:18725680

    One approach to address asthma disparities has been to create evidence-based guidelines to standardize asthma care and education. However, the adoption of these recommendations has been suboptimal among many providers. As a result, low-income minority patients may not be receiving adequate instruction in asthma self-management. In addition, these patients may fail to follow guideline-based recommendations. We conducted 25 interviews to identify the extent to which urban low-income adults have received training in, and implement, self-management protocols for acute asthma. Twenty-five adults (92% female; 76% African American; mean age 39) were enrolled. Only one subject had received asthma self-management training and only 10 (40%) used short-acting beta-(2) agonist-based (SABA) self-management protocols for the early treatment of acute asthma. No subject used a peak flow meter or an asthma action plan. Most (52%) chose to initially treat acute asthma with complementary and alternative medicine (CAM) despite the availability of SABAs. Importantly, 21 (84%) preferred an integrated approach using both conventional and CAM treatments. Four themes associated with acute asthma self-management emerged from the qualitative analysis. The first theme safety reflected subjects' perception that CAM was safer than SABA. Severity addressed the calculation that subjects made in determining if SABA or CAM was indicated based on the degree of symptoms they were experiencing. The third theme speed and strength of the combination described subjects' belief in the superiority of integrating CAM and SABA for acute asthma self-management. The final themesense of identity spoke to the ability of CAM to provide a customized self-management strategy that subjects desired. It is unclear if subjects' greater use of CAM or delays in using SABA-based self-management protocols were functions of inadequate instruction or personal preference.

    Eosinophils are granulocytes associated with host defense against parasitic helminths with allergic conditions and more recently, with immunoregulatory responses. Eosinophils are distinguished from leukocytes by their dominant population of cytoplasmic crystalloid (also termed secretory, specific, or secondary) granules that contain robust stores of diverse, preformed cationic proteins. Here, we provide an update on our knowledge about the unique and complex structure of human eosinophil crystalloid granules. We discuss their significance as rich sites of a variety of receptors and review our own recent research findings and those of others that highlight discoveries concerning the function of intracellular receptors and their potential implications in cell signaling. Special focus is provided on how eosinophils might use these intracellular receptors as mechanisms to secrete, selectively and rapidly, cytokines or chemokines and enable cell-free extracellular eosinophil granules to function as independent secretory structures. Potential roles of cell-free eosinophil granules as immune players in the absence of intact eosinophils will also be discussed. PMID:22672875

    The quality of social relationships may contribute to variations in biological stress responses, thereby affecting health risk. The association between an important indicator of social relationships, adult attachment style, and cortisol has been relatively unexplored. The present study examined adult romantic attachment style and cortisol responses to acute laboratory stress. Salivary cortisol was measured in response to two behavioural tasks, a colour/word interference task and mirror tracing task, in 498 healthy men and women from the Heart Scan study, a subsample of the Whitehall II cohort. Participants were classified as secure, fearful, preoccupied or dismissive on the basis of responses to the Relationship Questionnaire. Cortisol output was lowest in the fearful group, followed by the preoccupied group, with both secure and dismissive groups having higher levels. The results from this study tentatively support the proposition that attachment style is a factor in determining the manifestation of HPA dysregulation. PMID:21106296

    Despite recent increases in the cure rate of acute lymphoblastic leukemia (ALL), adult ALL remains a high-risk disease that exhibits a high relapse rate. In this study, we found that the histone demethylase retinoblastoma binding protein-2 (RBP2) was overexpressed in both on-going and relapse cases of adult ALL, which revealed that RBP2 overexpression was not only involved in the pathogenesis of ALL but that its overexpression might also be related to relapse of the disease. RBP2 knockdown induced apoptosis and attenuated leukemic cell viability. Our results demonstrated that BCL2 is a novel target of RBP2 and supported the notion of RBP2 being a regulator of BCL2 expression via directly binding to its promoter. As the role of RBP2 in regulating apoptosis was confirmed, RBP2 overexpression and activation of BCL2 might play important roles in ALL development and progression. PMID:27008505

  12. Use of AN Eosinophil Specific Monoclonal Antibody in Assessing Eosinophil Function.

    NASA Astrophysics Data System (ADS)

    Minkoff, Marjorie Sue

    A monoclonal antibody to an eosinophil specific determinant is very important in assessing eosinophil function during helminthic infection. Eosinophils induced by Schistosoma mansoni infection in BALB/c mice were used to induce C57B1/6 immunocytes for production of hybridomas secreting eosinophil monoclonal antibodies. These antibodies were shown to react with an eosinophil surface epitope but not with neutrophils or macrophages as determined by ELISA, immunodiffusion, immunofluorescence, and immunoblot assay. Affinity chromatography with eosinophil chemotactic factor-sepharose consistently selected out a { rm M_ R} 67,000 protein from solubilized eosinophil membrane antigens but not from neutrophil and macrophage antigens. In vitro studies showed that the eosinophil-specific monoclonal antibodies abrogated antibody-dependent eosinophil -mediated killing of S. mansoni schistosomula using mouse, rat or human eosinophils. Neutrophil and macrophage killing activities were unaffected. The monoclonal antibodies effected complement-dependent lysis of mouse and rat eosinophils but not of human eosinophils. ECF-treated eosinophils showed enhanced killing of schistosomula which was blocked by the monoclonal antibody. Murine and human eosinophils preincubated with monoclonal antibody exhibited decreased chemotaxis to ECF at optimal chemotactic concentrations. The monoclonal antibody also blocked eosinophil binding to ECF- sepharose beads. In vivo induction of peripheral blood eosinophilia by injection of S. mansoni eggs was suppressed by injections of monoclonal antibodies 2CD13 and 2QD45 in mouse and rat experimental models. Eosinophilia induced by keyhole limpet hemocyanin- cyclophosphamide treatment was also suppressed by monoclonal antibody in both murine and rat systems. Pulmonary granulomas in mice given egg injection and monoclonal antibody were smaller and contained fewer eosinophils than those granulomas from mice given eggs only.

The negative effects of solar radiation are accumulated during the entire lifetime; however 80% of total lifetime sun exposure is taking place before the age of 18 years. Child skin is more sensitive than adult skin because natural defense mechanisms are not fully developed. A short exposure to midday sun will result in sunburns. Epidemiologic studies show a higher incidence of malignant melanoma in persons with a history of sunburns during childhood and adolescence. Sun exposure among infants and pre-school children is largely dependent on the discretion of adult care providers. Sun protective habits of mothers may predict the level of sun exposure in children. It is very important to transfer the knowledge and positive habits of proper sun protection to children. The purpose of sun-safety behavior is not to avoid outdoor activities, but rather to protect the skin from detrimental sun effects. Proper sun protection of children includes protection from excessive sun exposure, sunburns and other forms of skin damage caused by sun, which may lead to the future development of skin cancers. This paper reviews acute skin reactivity to sun in childhood and adolescence that causes damage in skin structure and function and produces undesirable chronic changes in adults.

    Eosinophilic folliculitis (EF) is an idiopathic dermatitis included in the spectrum of eosinophilic pustular follicular reactions. Demodex folliculorum has been implicated as contributing to the pathogenesis of human immunodeficiency virus-associated EF, but it has not been described outside this context. We present an immunocompetent 65-year-old white man with a 5-year history of recurrent pruritic erythematous and oedematous lesions on his face, neck and scalp. Histopathologically, an eosinophilic microabcess with Demodex folliculorum mite within a pilosebaceous follicle was seen, and considered the causal agent. There were also accumulations of eosinophil granules on collagen bundles, and flame figure formations in the dermis. We believe that 'eosinophilic follicular reaction' is an appropriate term to describe this case of EF induced by D. folliculorum and thus distinguish it from the idiopathic form of EF. Moreover, this case suggests that D. folliculorum can sometimes induce an eosinophilic immune reaction. PMID:25623943

    The degranulation response of purified human eosinophils to platelet-activating factor (PAF) has been studied. PAF induced release of eosinophil peroxidase (EPO) and beta-glucuronidase from highly purified human eosinophils with an EC50 of 0.9 nM. The order of release was comparable with that induced by phorbol myristate acetate (PMA). The new specific PAF antagonist 3-[4-(2-chlorophenyl)-9-methyl-H-thieno[3,2-f] [1,2,4]triazolo-[4,3a][1,4]-diazepin-2-yl](4-morpholinyl)- 1-propane-one (WEB 2086) inhibited the PAF-induced enzyme release by human eosinophils in a dose-dependent manner. The viability of eosinophils were unaffected both by PAF and WEB 2086. The results suggest that PAF may amplify allergic and inflammatory reactions by release of preformed proteins from eosinophil granules. PMID:3410498

    EoE is a chronic immune/antigen-mediated clinicopathologic condition that has become an increasingly important cause of upper gastrointestinal morbidity in adults and children over the past 2 decades. It is diagnosed based on symptoms of esophageal dysfunction, the presence of at least 15 eosinophils/high-power field in esophageal biopsies, and exclusion of competing causes of esophageal eosinophilia, including proton pump inhibitor-responsive esophageal eosinophilia (PPI-REE). We review what we have recently learned about the clinical aspects of EoE, discussing the clinical, endoscopic, and histologic features of EoE in adults and children. We explain the current diagnostic criteria and challenges to diagnosis, including the role of gastroesophageal reflux disease and PPI-REE. It is also important to consider the epidemiology of EoE (current incidence of 1/10,000 new cases per year and prevalence of 0.5-1/1,000 cases per year) and disease progression. We review the main treatment approaches and new treatment options; EoE can be treated with topical corticosteroids such as fluticasone and budesonide, or dietary strategies, such as amino acid-based formulas, allergy test-directed elimination diets, and non-directed empiric elimination diets. Endoscopic dilation has also become an important tool for treatment of fibrostenostic complications of EoE. There are number of unresolved issues in EoE, including phenotypes, optimal treatment endpoints, the role of maintenance therapy, and treatment of refractory EoE. The care of patients with EoE and the study of the disease span many disciplines—EoE is ideally managed by a multidisciplinary team of gastroenterologists, allergists, pathologists, and dieticians.

    The intraosseous (IO) access initiative at an urban university adult level 1 trauma center began from the need for a more expeditious vascular access route to rescue patients in extremis. The goal of this project was a multidisciplinary approach to problem solving to increase access of IO catheters to rescue patients in all care areas. The initiative became a collaborative effort between nursing, physicians, and pharmacy to embark on an acute care endeavor to standardize IO access. This is a descriptive analysis of processes to effectively develop collaborative strategies to navigate hospital systems and successfully implement multilayered initiatives. Administration should empower nurse to advance their practice to include IO for patient rescue. Intraosseous access may expedite resuscitative efforts in patients in extremis who lack venous access or where additional venous access is required for life-saving therapies. Limiting IO dwell time may facilitate timely definitive venous access. Continued education and training by offering IO skill laboratory refreshers and annual e-learning didactic is optimal for maintaining proficiency and knowledge. More research opportunities exist to determine medication safety and efficacy in adult patients in the acute care setting. PMID:26352658

    Traumatic brain injury (TBI) has been known to be the leading cause of breakdown and long-term disability in people under 45 years of age. This study highlights the effective factors on post-traumatic (PT) linguistic disorder and relations between linguistic and cognitive function after trauma in adults with acute TBI. A cross-sectional design was employed to study 60 post-TBI hospitalized adults aged 18-65 years. Post-traumatic (PT) linguistic disorder and cognitive deficit after TBI were respectively diagnosed using the Persian Aphasia Test (PAT) and Persian version of Mini-Mental State Examination (MMSE) at discharge. Primary post-resuscitation consciousness level was determined using the Glasgow Coma Scale (GCS). Paracilinical data was obtained by CT scan technique. Multiple logistic regression analysis illustrated that brain injury severity was the first powerful significant predictor of PT linguistic disorder after TBI and frontotemporal lesion was the second. It was also revealed that cognitive function score was significantly correlated with score of each language skill except repetition. Subsequences of TBI are more commonly language dysfunctions that demand cognitive flexibility. Moderate, severe and fronto-temporal lesion can increase the risk of processing deficit in linguistic macrostructure production and comprehension. The dissociation risk of cortical and subcortical pathways related to cognitive-linguistic processing due to intracranial lesions can augment possibility of lexical-semantic processing deficit in acute phase which probably contributes to later cognitive-communication disorder.

    Background Dengue is an emerging infectious disease of global significance. Suspected dengue, especially in children in Nicaragua’s heavily-urbanized capital of Managua, has been well documented, but unsuspected dengue among children and adults with undifferentitated fever has not. Methodology/Principal Findings To prospectively study dengue in semi-urban and rural western Nicaragua, we obtained epidemiologic and clinical data as well as acute and convalescent sera (2 to 4 weeks after onset of illness) from a convenience sample (enrollment Monday to Saturday daytime to early evening) of consecutively enrolled patients (n = 740) aged ≥ 1 years presenting with acute febrile illness. We tested paired sera for dengue IgG and IgM and serotyped dengue virus using reverse transcriptase-PCR. Among 740 febrile patients enrolled, 90% had paired sera. We found 470 (63.5%) were seropositive for dengue at enrollment. The dengue seroprevalance increased with age and reached >90% in people over the age of 20 years. We identified acute dengue (serotypes 1 and 2) in 38 (5.1%) patients. Only 8.1% (3/37) of confirmed cases were suspected clinically. Conclusions/Significance Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

    Eosinophilic gastroenteritis is an uncommon disease with an obscure etiology, although associations with allergy, the idiopathic hypereosinophilic syndrome, and connective tissue disease have been reported. We present the case of a 37-year-old woman with a history of idiopathic thrombocytopenic purpura who presented with refractory nausea, vomiting, and abdominal pain. Imaging studies were significant for bowel wall thickening and ascites, while laboratory studies revealed a positive antinuclear antibody (ANA), a positive anti-double stranded (DS) DNA antibody, low complement, and proteinuria. Exploratory laparotomy with gastric and small bowel biopsies established the diagnosis of eosinophilic gastroenteritis. In addition, the patient met clinical criteria for the diagnosis of systemic lupus erythematosus. Previous studies have described eosinophilic gastroenteritis in patients with scleroderma, polymyositis, or dermatomyositis. This is the first report to our knowledge of an individual with eosinophilic gastroenteritis and systemic lupus erythematosus. PMID:15492606

    Background Previous studies have demonstrated that adolescent and adult rats show differential sensitivity to many of the acute effects of alcohol. We recently reported evidence of developmental differences in the effects of acute alcohol on the cortical electroencephalogram (EEG). However, it is unclear whether developmental differences are also observed in other neurophysiological and neurobehavioral measurements known to be sensitive to alcohol exposure. The present study determined the age-related effects of acute alcohol on behavioral and event-related potential (ERP) responses to acoustic startle (AS) and prepulse inhibition (PPI). Methods Male adolescent and adult Wistar rats were implanted with cortical recording electrodes. The effects of acute alcohol (0.0, 0.75, and 1.5 g/kg) on behavioral and ERP responses to AS and PPI were assessed. Results Acute alcohol (0.75 and 1.5 g/kg) significantly reduced the behavioral and electrophysiological response to AS in adolescent and adult rats. Both 0.75 and 1.5 g/kg alcohol significantly enhanced the behavioral response to PPI in adolescent, but not in adult rats. During prepulse+pulse trials, 1.5 g/kg alcohol significantly increased the N10 pulse response in the adolescent frontal cortex. Acute alcohol (0.75 and 1.5 g/kg) also increased the N1 ERP pulse response to prepulse stimuli in frontal and parietal cortices in adult rats, but not in adolescent rats. Conclusions These data suggest that alcohol’s effect on behavioral and electrophysiological indices of AS do not differ between adults and adolescents whereas developmental stage does appear to significantly modify alcohol influenced response to PPI.

    Eosinophilic polymorphonuclear leukocytes were isolated from the peritoneal cavity of BALB/c mice infected with the parasite Mesocestoides corti. Approximately 4 X 10(7) eosinophils (purity, 50%) could be harvested from each mouse. A high yield and purity of eosinophils was obtained from the peritoneal cells of infected male BALB/c mice using density centrifugation on a gradient of slightly hypotonic colloidal silica sol (Percoll). After initial irradiation of the mice to lower the lymphocyte contamination, subsequent density gradient (and where necessary sedimentation velocity) centrifugation yielded 10(8) eosinophils (purity > 95%) from six to eight mice. It was also possible to isolate small numbers of eosinophils (2 X 10(4) cells/minute, purity > 99%) without irradiating the mice. This could be achieved by separating the density gradient purified peritoneal cells by light-scatter on a Becton-Dickinson cell sorter (FACS II). Analysis of proteins extracted from eosinophils using polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate revealed a group of high molecular weight proteins (bwtween 250K and 160K) which were not as distinctive in the neutrophil profile. Surface labeling was performed, before the cell separation by using 125I and 1,3,4,6-tetrachloro-3 alpha, 6 alpha-diphenylglycoluril. Only five 125I-labeled proteins were detected initially (all with apparent molecular weights > 50,000). No 125I appeared to be associated with actin under the conditions used for surface labeling. Four of the eosinophil surface labeled proteins corresponded to surface labeled proteins on neutrophils, but the major surface component of the eosinophils (MW 79,000) appeared to be smaller than the major neutrophil protein (MW 90,000).

    OBJECTIVE Acute hypoglycemia impairs cognitive function in several domains. Executive cognitive function governs organization of thoughts, prioritization of tasks, and time management. This study examined the effect of acute hypoglycemia on executive function in adults with and without diabetes. RESEARCH DESIGN AND METHODS Thirty-two adults with and without type 1 diabetes with no vascular complications or impaired awareness of hypoglycemia were studied. Two hyperinsulinemic glucose clamps were performed at least 2 weeks apart in a single-blind, counterbalanced order, maintaining blood glucose at 4.5 mmol/L (euglycemia) or 2.5 mmol/L (hypoglycemia). Executive functions were assessed with a validated test suite (Delis-Kaplan Executive Function). A general linear model (repeated-measures ANOVA) was used. Glycemic condition (euglycemia or hypoglycemia) was the within-participant factor. Between-participant factors were order of session (euglycemia-hypoglycemia or hypoglycemia-euglycemia), test battery used, and diabetes status (with or without diabetes). RESULTS Compared with euglycemia, executive functions (with one exception) were significantly impaired during hypoglycemia; lower test scores were recorded with more time required for completion. Large Cohen d values (>0.8) suggest that hypoglycemia induces decrements in aspects of executive function with large effect sizes. In some tests, the performance of participants with diabetes was more impaired than those without diabetes. CONCLUSIONS Executive cognitive function, which is necessary to carry out many everyday activities, is impaired during hypoglycemia in adults with and without type 1 diabetes. This important aspect of cognition has not received previous systematic study with respect to hypoglycemia. The effect size is large in terms of both accuracy and speed. PMID:23780950

    Purpose: Efficacy and acute toxicity of proton craniospinal irradiation (p-CSI) were compared with conventional photon CSI (x-CSI) for adults with medulloblastoma. Methods and Materials: Forty adult medulloblastoma patients treated with x-CSI (n=21) or p-CSI (n=19) at the University of Texas MD Anderson Cancer Center from 2003 to 2011 were retrospectively reviewed. Median CSI and total doses were 30.6 and 54 Gy, respectively. The median follow-up was 57 months (range 4-103) for x-CSI patients and 26 months (range 11-63) for p-CSI. Results: p-CSI patients lost less weight than x-CSI patients (1.2% vs 5.8%; P=.004), and less p-CSI patients had >5% weight loss compared with x-CSI (16% vs 64%; P=.004). p-CSI patients experienced less grade 2 nausea and vomiting compared with x-CSI (26% vs 71%; P=.004). Patients treated with x-CSI were more likely to have medical management of esophagitis than p-CSI patients (57% vs 5%, P<.001). p-CSI patients had a smaller reduction in peripheral white blood cells, hemoglobin, and platelets compared with x-CSI (white blood cells 46% vs 55%, P=.04; hemoglobin 88% vs 97%, P=.009; platelets 48% vs 65%, P=.05). Mean vertebral doses were significantly associated with reductions in blood counts. Conclusions: This report is the first analysis of clinical outcomes for adult medulloblastoma patients treated with p-CSI. Patients treated with p-CSI experienced less treatment-related morbidity including fewer acute gastrointestinal and hematologic toxicities.

    In acute myelogenous leukemia, the persistent detection of abnormal cytogenetics at complete remission (ACCR) is associated with inferior outcomes. However, the prognostic significance of ACCR in adult patients with acute lymphoblastic leukemia (ALL) is unknown. We evaluated 272 adult patients with ALL and abnormal cytogenetics at baseline who were treated with frontline induction chemotherapy, achieved complete remission (CR) and had cytogenetic analysis performed at the time of CR. ACCR was observed in 26 patients (9.6%). Median relapse-free survival was 22 months (95% CI, 12 months to not reached) for patients with ACCR vs. 48 months (range, 30-125 months) in patients with normal cytogenetics at CR (NCCR; P = 0.31). Median overall survival also did not differ significantly between the ACCR (99 months [range, 17 months to not reached]) and NCCR groups (67 months [range, 47 months to not reached], P = 0.86). The specificity of ACCR for minimal residual disease (MRD) positivity by multi-parameter flow cytometry (MFC) was 43%, and there was overall poor correlation between these two methods for the detection of residual disease. When patients were stratified by MRD status, the presence or absence of persistent cytogenetic abnormalities at CR did not add additional prognostic information. This study suggests that there is poor association between MRD assessment by MFC and the presence or absence of cytogenetic abnormalities at CR in adult patients with ALL. ACCR was not associated with adverse outcomes in ALL and did not add additional prognostic information when MRD status by MFC was known. PMID:26800008

    Discovery of non-invasive diagnostic and predictive biomarkers for acute rejection in liver transplant patients would help to ensure the preservation of liver function in the graft, eventually contributing to improved graft and patient survival. We evaluated selected cytokines and chemokines in the sera from liver transplant patients as potential biomarkers for acute rejection, and found that the combined detection of IL-10, IL-17, and CXCL10 at 1-2 weeks post-operation could predict acute rejection following adult liver transplantation with 97% specificity and 94% sensitivity.

    The purpose of the paper is to compare the results of two studies in which the respiratory responses of children and adults to acute ozone (O/sub 3/) exposure were measured. Forty-two 18-30 year old males were exposed for 2.5 hours in a controlled environmental chamber to either 0.0 or 0.12 ppm O3 while performing intermittent heavy exercise. Twenty-two 8-11 year old males were exposed in a similar manner to both air and 0.12 ppm O3. Measures of respiratory symptoms and function were made before and after exposure. Adults experienced an increase in the symptom cough and decrements in forced vital capacity and some measures of forced expiratory flow. Children experienced similar decrements in pulmonary function, but had no increase in symptoms. The authors concluded that as measured by pulmonary function children appear to be no more responsive to O3 exposure than are adults and may experience fewer symptoms.

    Tumor immune escape mechanism mediated by CD4+CD25+regulatory T cells (Tregs) is a key factor in the pathogenesis of acute myeloid leukemia (AML). IL-35, as a novel inhibitory cytokine, is produced by Tregs specially and regulates functions of Tregs in murine. However, IL-35 expression of Tregs in human is still disputed, and its role in AML is yet to be elucidated. In this study, we found that IL-35 was expressed highly in peripheral blood plasma of adult patients with AML and significantly correlated with the clinical stages of malignancy. Tregs-derived from adult AML patients produced IL-35 in a stimulation-dependent manner. IL-35 promoted AML blasts immune escape by expanding Tregs and inhibiting CD4+CD25-effector T cells (Teffs). Furthermore, IL-35 directly promoted the proliferation of AML blasts and reduced the apoptosis of AML blasts. Together, our study demonstrates that IL-35-derived from Tregs promotes the growth of adult AML blasts, suggesting that IL-35 has an important role in the pathogenesis of AML.

    Most adults with sickle cell disease (SCD) receive care for their acute painful episodes in an emergency department (ED) setting. The purpose of this article is to describe the impact of opening a dedicated treatment center for adults with SCD [Sickle Cell Infusion Clinic (SCIC)] on patient outcomes and on hospital discharges for SCD. Descriptive data including demographics, time to first dose of narcotic, and pain scores were collected on patients presenting to the SCIC and ED. Maryland hospital discharge data were obtained from the Maryland Health Services Cost Review Commission. Analyses were conducted using T tests, χ(2) tests, and simple generalized estimating equation regression models accounting for the clustered nature of observations, as appropriate. There were 3,874 visits to the SCIC by 361 unique patients; 85% of those visits resulted in the patient being sent home. During the same time period, there were 3,408 visits to the ED by 558 unique patients with SCD. The overall admission rate from the ED for these patients was 35.9% but decreased significantly over the time period with a rate of 20% in December 2011. There was a significant decrease in readmissions over time for the entire Baltimore Metro area with the likelihood of readmission decreasing by 7% over time. The SCIC model provides adults with SCD access to high quality care that decreases the need for hospital admission. Further research needs to be done to evaluate the cost effectiveness of this model.

    Because a pediatric-inspired Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) protocol yielded a markedly improved outcome in adults with Philadelphia chromosome-negative ALL, we aimed to reassess the role of allogeneic stem cell transplantation (SCT) in patients treated in the GRAALL-2003 and GRAALL-2005 trials. In all, 522 patients age 15 to 55 years old and presenting with at least 1 conventional high-risk factor were candidates for SCT in first complete remission. Among these, 282 (54%) received a transplant in first complete remission. At 3 years, posttransplant cumulative incidences of relapse, nonrelapse mortality, and relapse-free survival (RFS) were estimated at 19.5%, 15.5%, and 64.7%, respectively. Time-dependent analysis did not reveal a significant difference in RFS between SCT and no-SCT cohorts. However, SCT was associated with longer RFS in patients with postinduction minimal residual disease (MRD) ≥10(-3) (hazard ratio, 0.40) but not in good MRD responders. In B-cell precursor ALL, SCT also benefitted patients with focal IKZF1 gene deletion (hazard ratio, 0.42). This article shows that poor early MRD response, in contrast to conventional ALL risk factors, is an excellent tool to identify patients who may benefit from allogeneic SCT in the context of intensified adult ALL therapy. Trial GRAALL-2003 was registered at www.clinicaltrials.gov as #NCT00222027; GRAALL-2005 was registered as #NCT00327678. PMID:25587040

    Using a serological test, different criteria have been established for classifying a case as primary or secondary dengue virus infection. Considering the dengue epidemiological situation in Cuba, IgG antibody response to dengue virus infection in serum samples from children and adults with a dengue 3 infection, in Havana city during the 2001-2002 epidemic was evaluated. Samples were collected on days 5-7 of fever onset and tested by an ELISA inhibition. A total of 713 serum samples positive for IgM antibody, 93 from children and 620 from adult patients were studied. Serum samples collected from healthy blood donors and patients not infected with dengue were included as controls. An IgG primary infection pattern was observed in sera collected from children, with titers of < or =20 in the 89.3% of the patients, while both, a primary and secondary patterns were observed in sera collected from adult patients with titers of < or =20 (13.4%) and > or =1280 (83.9%), respectively. These results permitted the definition of a primary or secondary case of dengue virus infection in serum samples collected during the acute phase of dengue virus infection.

  13. Best Practices in Adolescent and Young Adult Patients with Acute Lymphoblastic Leukemia: A Focus on Asparaginase

    2015-01-01

    The inclusion of asparaginase in chemotherapy regimens to treat acute lymphoblastic leukemia (ALL) has had a positive impact on survival in pediatric patients. Historically, asparaginase has been excluded from most treatment protocols for adolescent and young adult (AYA) patients because of perceived toxicity in this population, and this is believed to have contributed to poorer outcomes in these patients. However, retrospective analyses over the past 12 years have shown that 2-, 5-, and 7-year overall survival of AYA patients is significantly improved with pediatric versus adult protocols. The addition of asparaginase to adult protocols yielded high rates of first remission and improved survival. However, long-term survival remains lower compared with what has been seen in pediatrics. The notion that asparaginase is poorly tolerated by AYA patients has been challenged in multiple studies. In some, but not all, studies, the incidences of hepatic and pancreatic toxicities were higher in AYA patients, whereas the rates of hypersensitivity reactions did not appear to differ with age. There is an increased risk of venous thromboembolic events, and management with anti-coagulation therapy is recommended. Overall, the risk of therapy-related mortality is low. Together, this suggests that high-intensity pediatric protocols offer an effective and tolerable approach to treating ALL in the AYA population. PMID:26421220

    Because a pediatric-inspired Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL) protocol yielded a markedly improved outcome in adults with Philadelphia chromosome-negative ALL, we aimed to reassess the role of allogeneic stem cell transplantation (SCT) in patients treated in the GRAALL-2003 and GRAALL-2005 trials. In all, 522 patients age 15 to 55 years old and presenting with at least 1 conventional high-risk factor were candidates for SCT in first complete remission. Among these, 282 (54%) received a transplant in first complete remission. At 3 years, posttransplant cumulative incidences of relapse, nonrelapse mortality, and relapse-free survival (RFS) were estimated at 19.5%, 15.5%, and 64.7%, respectively. Time-dependent analysis did not reveal a significant difference in RFS between SCT and no-SCT cohorts. However, SCT was associated with longer RFS in patients with postinduction minimal residual disease (MRD) ≥10(-3) (hazard ratio, 0.40) but not in good MRD responders. In B-cell precursor ALL, SCT also benefitted patients with focal IKZF1 gene deletion (hazard ratio, 0.42). This article shows that poor early MRD response, in contrast to conventional ALL risk factors, is an excellent tool to identify patients who may benefit from allogeneic SCT in the context of intensified adult ALL therapy. Trial GRAALL-2003 was registered at www.clinicaltrials.gov as #NCT00222027; GRAALL-2005 was registered as #NCT00327678.

    The purpose of this work was to assess the clinical and epidemiologic presentation features of adult acute diarrhea in a general hospital form Córdoba City. All the patients older than 14 years old who assisted to the Hospital Nacional de Clínicas Central Guard for acute diarrhea, during the periods: A (15-12-89 to 15-03-90), B (15-12-93 to 15-03-94) and C (15-12-94 to 15-03-95), were included. 594 patients were studied: 337 female (56.7%) and 257 male, 143 in the period A, 250 in B and 201 in C. The means +/- SD age was 34.6 +/- 13.3 and stool loose per day at admission 7.3 +/- 4.7. Eighty six percent of patients presented liquid consistent stool, 89.6% abdominal pain, 44.7% vomiting and 18.8% bloody stools. The rate of patients who consulted Central Guard referring acute diarrhea increased from period A (2.4%) to B (3.61%); p = 0.002 and decreased form B to C (2.85%); p = 0.01. The mean (+/- SD) days transcurred from the beginning of diarrhea episode till consultation was 3.5 +/- 2.7; 2.7 +/- 2.3 y 2.9 +/- 3.5 in the periods A, B and C respectively, statistically significant difference between A and B, p < 0.01.

    Background Beyond their lipid-lowering abilities, statins have anti-inflammatory and immunomodulatory properties. In view of these effects, a growing interest has emerged in the possible role of statins, in preventing or decreasing morbidity and mortality from infection. Objectives The aim of this study was to determine whether previous statin use is associated with reduced risk of acute bacterial infections and better outcome of these infections. Materials and Methods In this historical cohort study, consecutive adult patients admitted with acute bacterial infection were enrolled. Control group were selected from adult outpatient and without history of acute bacterial infections. Acute bacterial infections included in this study were; pneumonia, acute pyelonephritis, cellulitis and sepsis with unknown origin. Data about baseline characteristics, co-morbidities and statins use of two groups was obtained. Results Finally 144 patients met inclusion criteria and were enrolled. Same numbers of controls were selected. Two groups were matched based on most baseline characteristics and co-morbidities. The patients’ categories were as follows: pneumonia 42.3%, acute pyelonephritis 23.6%, cellulitis 16% and sepsis 18%. From all participants 29.9% of patients and 45.8% controls were statin users. There was significant association between previous statin use and reduced risk of acute bacterial infections (Mantel Haenszel Weighted Odds Ratio=0.51, 95% CI: 0.30-0.85, p=0.009). Duration of hospitalization was significantly shorter in statin users (p=0.002). Hospital mortality rate was lower (14.6%) in statins users when compared with non-users (18.8%) with significant difference (p=0.028). Conclusion Prior therapy with statins is associated with considerably reduced onset of acute bacterial infections and better outcome in adult patients. PMID:26676277

    Lymphoid enhancer factor 1 (LEF1) is a key transcription factor in Wingless-type (Wnt) pathway. The present study was aimed to explore the genetic mutation and expression of LEF1, and their clinical significance in adult patients with acute lymphocytic leukemia (ALL). Genomic DNA was amplified and sequenced to detect the mutation of LEF1 in 131 newly diagnosed adult patients with ALL. Quantitative PCR (qPCR) was performed to detect the expression of LEF1. Moreover, the correlations between mutations and expression of LEF1 with clinical characteristics were analyzed. The results showed that the frequency of LEF1 mutation in adult ALL was 3.1% (4/131) and all of them were point mutations located in exon 2 and 3; the median white blood cell count and median percentage of blasts at diagnosis were significantly higher in LEF1 high expression group than in low expression group (70.6 × 10⁹/L vs 26.2 × 10⁹/L)(P = 0.010); (81.0% vs 57.0%) (P = 0.014); in addition, the percentage of patients with Philadelphia chromosome positive and patients in high-risk group significantly increased in LEF1 high expression group compared with that in low expression group (66.7% vs 36.5%) (P = 0.038); (79.2% vs 56.2%) (P = 0.044). It is concluded that high expression of LEF1 may play an important role on development of adult ALL.

    Current salvage regimens achieve complete remission (CR) in about a third of adults with relapsed/refractory acute lymphoblastic leukemia (ALL), and this represents a major barrier for performing allogeneic hematopoietic stem cell transplant (HSCT), the only potentially curative treatment. We conducted in adults with first relapse of ALL, a prospective clinical trial with intensive regimen derived from the pediatric Berlin-Frankfurt-Muenster-85 protocol, with addition of a continuous infusional multi-agent chemotherapy in phase II induction followed by consolidation with alternating monthly cycles. Objectives of this study included CR rate, leukemia-free survival (LFS) and toxicity of the regimen in adults. We report the outcome of 19 patients (19-51 years of age) treated prospectively on the study, as well as a subsequent cohort of 31 patients (18-53 years of age) treated off the study. Thirteen of 19 (68%) patients from the initial prospective study achieved CR, and the median overall survival (OS) of these 13 CR patients was 10.3 months. The median OS and LFS of all 19 patients were 5.6 and 4.3 months, respectively. The regimen was well tolerated, and no grade 4 non-hematological toxicity was observed. Of the 31 patients treated off the study and analyzed retrospectively, 16 (52%) achieved CR. After including all 50 patients, the CR rate was 58%. The regimen used in this trial appears to be feasible and effective salvage therapy option for adult patients younger than age 55 with relapsed ALL, produced a high CR rate and could facilitate subsequent allogeneic HSCT.

    Background Most cases of adult pertussis probably remain undiagnosed. Aim To explore the prevalence, diagnosis, and disease course of acute pertussis infection in adult patients presenting with acute cough. Design and setting Prospective observational study between 2007 and 2010 in primary care in 12 European countries. Method Adults presenting with acute cough (duration of ≤28 days) were included. Bordetella pertussis infection was determined by polymerase chain reaction (from nasopharyngeal flocked swabs and sputa) and by measurement of immunoglobulin G antibodies to pertussis toxin (PT) in venous blood at day 28. An antibody titre to PT of ≥125 IU/ml or PCR positive result in a respiratory sample defined recent infection. Patients completed a symptom diary for 28 days. Results Serum and/or respiratory samples were obtained in 3074 patients. Three per cent (93/3074) had recent B. pertussis infection. Prior cough duration >2 weeks discriminated to some extent between those with and without pertussis (adjusted odds ratio 1.89, 95% confidence interval = 1.17 to 3.07; P = 0.010). Median cough duration after presentation was 17 and 12 days in patients with and without pertussis, respectively (P = 0.008). Patients with pertussis had longer duration of phlegm production (P = 0.010), shortness of breath (P = 0.037), disturbed sleep (P = 0.013) and interference with normal activities or work (P = 0.033) after presentation. Conclusion Pertussis infection plays a limited role among adults presenting with acute cough in primary care, but GPs should acknowledge the possibility of pertussis in uncomplicated lower respiratory tract infection. As in children, pertussis also causes prolonged symptoms in adults. However, pertussis is difficult to discern from other acute cough syndromes in adults at first presentation. PMID:26412843

    Eosinophilic myenteric ganglionitis is a disorder characterized by infiltration of the Auerbach plexus by eosinophils. It can be associated with a bowel dysmotility and a few cases of intestinal pseudo-obstructive syndrome have been described in children. In this case report, we present an elderly 93-year-old woman who presented with episodes of functional bowel obstruction of unknown etiology. After several admissions for recurrent obstipation requiring fecal disimpaction, she had a Hartmann procedure performed with a resection of the sigmoid colon. The sigmoid colon was markedly dilated and the only significant finding on histology was infiltration of the Auerbach plexus by eosinophils. The mucosa and the muscular layers appeared unremarkable. Her symptoms resolved after the resection and the patient is currently well after 5 months. Recurrent gastrointestinal pseudo-obstruction can arise secondary to eosinophilic myenteric ganglionitis even in adults. Clinical improvement is likely if this disease entity is promptly recognized and treated.

    Context Eosinophilic renal neoplasms include a spectrum of solid and papillary tumors ranging from indolent benign oncocytoma to highly aggressive malignancies. Recognition of the correct nature of the tumor, especially in biopsy specimens, is paramount for patient management. Objective To review the diagnostic approach to eosinophilic renal neoplasms with light microscopy and ancillary techniques. Data Sources Review of the published literature and personal experience. Conclusions The following tumors are in the differential diagnosis of oncocytic renal cell neoplasm: oncocytoma, chromophobe renal cell carcinoma (RCC), hybrid tumor, tubulocystic carcinoma, papillary RCC, clear cell RCC with predominant eosinophilic cell morphology, follicular thyroid-like RCC, hereditary leiomyomatosis–associated RCC, acquired cystic disease–associated RCC, rhabdoid RCC, microphthalmia transcription factor translocation RCC, epithelioid angiomyolipoma, and unclassified RCC. In low-grade nonpapillary eosinophilic neoplasms, distinction between oncocytoma and low-grade RCC mostly rests on histomorphology; however, cytokeratin 7 immunostain may be helpful. In high-grade nonpapillary lesions, there is more of a role for ancillary techniques, including immunohistochemistry for cytokeratin 7, CA9, CD10, racemase, HMB45, and Melan-A. In papillary eosinophilic neoplasms, it is important to distinguish sporadic type 2 papillary RCC from microphthalmia transcription factor translocation and hereditary leiomyomatosis–associated RCC. Histologic and cytologic features along with immunohistochemistry and fluorescence in situ hybridization tests for TFE3 (Xp11.2) and TFEB [t(6;11)] are reliable confirmatory tests. Eosinophilic epithelial neoplasms with architecture, cytology, and/or immunoprofile not qualifying for either of the established types of RCC should be classified as unclassified eosinophilic RCC and arbitrarily assigned a grade (low or high).

    Cancer progresses with a change in the structure of the gene network in normal cells. We define a measure of organizational hierarchy in gene networks of affected cells in adult acute myeloid leukemia (AML) patients. With a retrospective cohort analysis based on the gene expression profiles of 116 AML patients, we find that the likelihood of future cancer relapse and the level of clinical risk are directly correlated with the level of organization in the cancer related gene network. We also explore the variation of the level of organization in the gene network with cancer progression. We find that this variation is non-monotonic, which implies the fitness landscape in the evolution of AML cancer cells is non-trivial. We further find that the hierarchy in gene expression at the time of diagnosis may be a useful biomarker in AML prognosis.

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

    2009-01-01

    SYNOPSIS Assays that measure minimal residual disease (MRD) can determine the response to treatment in patients with acute lymphoblastic leukemia (ALL) much more precisely than morphological screening of bone marrow smears. The clinical significance of MRD detected by flow cytometry or polymerase chain reaction-based methods in childhood ALL has been conclusively established. Hence, MRD is being used in several clinical trials to adjust treatment intensity. Similar findings have been gathered in adult patients with ALL, making MRD one of the most powerful and informative parameters to guide clinical management. This article discusses practical issues related to MRD methodologies and the evidence supporting the use of MRD for risk assignment in clinical trials. PMID:19825454

    2015-01-01

    Acute myeloid leukemia in adults is a highly heterogeneous disease. Gene expression profiling performed using unsupervised algorithms can be used to distinguish specific groups of patients within a large patient cohort. The identified gene expression signatures can offer insights into underlying physiological mechanisms of disease pathogenesis. Here, the analysis of several related gene expression clusters associated with poor outcome, worst overall survival and highest rates of resistant disease and obtained from the patients at the time of diagnosis or from previously untreated individuals is presented. Surprisingly, these gene clusters appear to be enriched for genes corresponding to proteins involved in transport across membranes (transporters, carriers and channels). Several ideas describing the possible relationship of membrane transport activity and leukemic cell biology, including the “Warburg effect,” the specific role of chloride ion transport, direct “import” of metabolic energy through uptake of creatine phosphate, and modification of the bone marrow niche microenvironment are discussed.

    Background Blood eosinophil counts have been documented as a good biomarker for patients with chronic obstructive pulmonary disease (COPD) using inhaled corticosteroid (ICS) therapy. However, the effectiveness and safety of prescribing high or medium dose of ICS for patients with different eosinophil counts are unknown. Methods A post hoc analysis of a previous prospective randomized study was performed for COPD patients using higher dose (HD: Fluticasone 1,000 μg/day) or medium dose (MD: Fluticasone 500 μg/day) of ICS combined with Salmeterol (100 μg/day). Patients were classified into two groups: those with high eosinophil counts (HE ≥3%) and those with low eosinophil counts (LE <3%). Lung function was evaluated with forced expiratory volume in 1 second, forced vital capacity, and COPD assessment test. Frequencies of acute exacerbation and pneumonia were also measured. Results Two hundred and forty-eight patients were studied and classified into higher eosinophil (HE) (n=85, 34.3%) and lower eosinophil (LE) groups (n=163, 65.7%). The levels of forced expiratory volume in 1 second were significantly increased in patients of HE group treated with HD therapy, compared with the other groups (HE/HD: 125.9±27.2 mL vs HE/MD: 94.3±23.7 mL, vs LE/HD: 70.4±20.5 mL, vs LE/MD: 49.8±16.7 mL; P<0.05) at the end of the study. Quality of life (COPD assessment test) markedly improved in HE/HD group than in MD/LE group (HE/HD: 9±5 vs LE/MD: 16±7, P=0.02). The frequency of acute exacerbation was more decreased in HE/HD group patients, compared with that in LE/MD group (HE/HD: 13.5% vs LE/MD: 28.7%, P<0.01). Pneumonia incidence was similar in the treatment groups (HE/HD: 3.2%, HE/MD: 2.6%, LE/HD: 3.5%, LE/MD 2.8%; P=0.38). Conclusion The study results support using blood eosinophil counts as a biomarker of ICS response and show the benefits of greater improvement of lung function, quality of life, and decreased exacerbation frequency in COPD patients with blood eosinophil

    The transition from wakefulness to sleep is associated with a pronounced decline in diuresis, a necessary physiological process that allows uninterrupted sleep. The aim of this study was to assess the effect of acute sleep deprivation (SD) on urine output and renal water, sodium, and solute handling in healthy young volunteers. Twenty young adults (10 male) were recruited for two 24-h studies under standardized dietary conditions. During one of the two admissions, subjects were deprived of sleep. Urine output, electrolyte excretions, and osmolar excretions were calculated. Activated renin, angiotensin II, aldosterone, arginine vasopressin, and atrial natriuretic peptide were measured in plasma, whereas prostaglandin E(2) and melatonin were measured in urine. SD markedly increased the diuresis and led to excess renal sodium excretion. The effect was more pronounced in men who shared significantly higher diuresis levels during SD compared with women. Renal water handling and arginine vasopressin levels remained unaltered during SD, but the circadian rhythm of the hormones of the renin-angiotensin-aldosterone system was significantly affected. Urinary melatonin and prostaglandin E(2) excretion levels were comparable between SD and baseline night. Hemodynamic changes were characterized by the attenuation of nocturnal blood pressure dipping and an increase in creatinine clearance. Acute deprivation of sleep induces natriuresis and osmotic diuresis, leading to excess nocturnal urine production, especially in men. Hemodynamic changes during SD may, through renal and hormonal processes, be responsible for these observations. Sleep architecture disturbances should be considered in clinical settings with nocturnal polyuria such as enuresis in children and nocturia in adults.

    Acute lymphoblastic leukaemia (ALL) is a heterogeneous group of disorders. It varies with respect to the morphologic, cytogenetic, molecular and immunologic features of the neoplastic cells reflecting the variable clinical-pathologic presentations and outcome of the patients. The aim of the study was to observe the clinical and haemato-pathological characteristics in newly diagnosed adult ALL patients. A total number of 61 patients morphologically diagnosed as acute lymphoblastic leukaemia aged 15 and above assigned for this observational study. The study was carried out in the Department of Haematology, BSMMU from January 2007 to December 2008. Among 61 patients, aged 15 to 80 years with median age 25 years, 79% were male and 21% were female. Most of the patients presented with anaemia (67%), fever (66%), lymphadenopathy (64%) and splenomegaly (57%). Other common clinical findings were hepatomegaly (39%), bone tenderness (44%) and bleeding manifestations (34%). Among haemato-pathological findings 67% patients had Hb level ≤10gm/dl, 46% patients had WBC count ≥30×10⁹/L, 67% patients had platelet count ≤100×10⁹/L, 93% patients had blast in peripheral blood and 61% patients had ≥90 % blasts in the bone marrow at the time of diagnosis. In this study adult ALL patients were analyzed only for their clinical and haemato-pathological characteristics. But their biologic characteristics were not analyzed due to lack of availability of facility. A progressive understanding of the biologic and genetic characteristics of ALL will allow us to identify different prognostic subgroups with specific molecular and cellular features. All the necessary measures have to be developed in our country in order to identify prognostically distinct subgroups of patients.

    Eosinophilic leukocytes function in host protection against parasitic worms. In turn, helminthic parasites harbor specific molecules to evade or paralyze eosinophil-associated host immune responses; these molecules facilitate the migration and survival of parasitic helminths in vivo. This competition between eosinophil and worm leads to stable equilibria between them. An understanding of such dynamic host-eosinophil interactions will help us to uncover mechanisms of cross talk between host and parasite in helminth infection. In this review, we examine recent findings regarding the innate immune responses of eosinophils to helminthic parasites, and discuss the implications of these findings in terms of eosinophil-mediated tissue inflammation in helminth infection.

    In order to establish guidelines for categorization of acute leukemia, marrow histology, special stains, and electron microscopy were performed in 100 adult leukemia cases. Differential counts for each stain were performed, and the results were combined with those obtained by electron microscopy for final classification. Myeloid (non-lymphoid) leukemia was most common (83 cases), and there were 13 lymphoid cases, two cases of erythroleukemia, and two undifferentiated leukemias. Histologic studies of marrow particles revealed significant admixtures of lymphocytes, plasma cells, and abnormal erythroid elements, particularly in acute myelomonocytic leukemia. Interpretations of cytochemical results were confirmed by ultrastructural studies in 90% of the cases. Clinically significant discrepancies between cytochemical and ultrastructural interpretations were rarely found. Only two myeloid and five lymphoid cases did not mark typically with any cytochemical stain. The single most reliable special stain was the periodic acid-Schiff stain, whereas the stain most difficult to interpret was the alpha-naphthyl acetate esterase stain. Sudan black stain was particularly helpful in demonstrating Auer rods. Five of six cases unclassified by cytochemistry were categorized by electron microscopy. Although patterns of cytochemical staining were delineated for each type of leukemia, significant intragroup variation in cytochemical reactions was recognized. This study indicates that ultrastructural examination should be routinely used for categorization of cases with equivocal cytochemical findings and for analysis of unclassified cases.

    MLL (mixed-lineage-leukemia) gene rearrangements are typical for acute leukemia and are associated with an aggressive course of disease, with a worse outcome than comparable case, and thus require intensified treatment. Here we describe a 69-year-old female with adult B cell precursor acute lymphoblastic leukemia (BCP-ALL) with hyperleukocytosis and immunophenotype CD10- and CD19+ with cryptic MLL rearrangements. G-banding at the time of diagnosis showed a normal karyotype: 46,XX. Molecular cytogenetics using multitude multicolor banding (mMCB) revealed a complex rearrangement of the two copies of chromosome 11. However, a locus-specific probe additionally identified that the MLL gene at 11q23.3 was disrupted, and that the 5′ region was inserted into the chromosomal sub-band 4q21; thus the aberration involved three chromosomes and five break events. Unfortunately, the patient died six months after the initial diagnosis from serious infections and severe complications. Overall, the present findings confirm that, by far not all MLL aberrations are seen by routine chromosome banding techniques and that fluorescence in situ hybridization (FISH) should be regarded as standard tool to access MLL rearrangements in patients with BCP-ALL.

  15. Potential Reparative Role of Resident Adult Renal Stem/Progenitor Cells in Acute Kidney Injury

    Abstract Human kidney is particularly susceptible to ischemia and toxins with consequential tubular necrosis and activation of inflammatory processes. This process can lead to the acute renal injury, and even if the kidney has a great capacity for regeneration after tubular damage, in several circumstances, the normal renal repair program may not be sufficient to achieve a successful regeneration. Resident adult renal stem/progenitor cells could participate in this repair process and have the potentiality to enhance the renal regenerative mechanism. This could be achieved both directly, by means of their capacity to differentiate and integrate into the renal tissues, and by means of paracrine factors able to induce or improve the renal repair or regeneration. Recent genetic fate-tracing studies indicated that tubular damage is instead repaired by proliferative duplication of epithelial cells, acquiring a transient progenitor phenotype and by fate-restricted clonal cell progeny emerging from different nephron segments. In this review, we discuss about the properties and the reparative characteristics of high regenerative CD133+/CD24+ cells, with a view to a future application of these cells for the treatment of acute renal injury.

    Recent advances in surgical corrections and supportive care for congenital heart disease have resulted in increasing numbers of adult survivors who may develop hematological malignancies. Treatments including chemotherapy for such patients may cause serious hemodynamic or cardiac complications, especially in those receiving stem cell transplantation. We present a 29-year-old woman with acute lymphoblastic leukemia and congenital heart disease. She had been diagnosed with pulmonary atresia with an intact ventricular septum at birth, and the anomaly was surgically corrected according to the Fontan technique at age 9 years. Her induction chemotherapy required modifications due to poor cardiac status with Fontan circulation. However, after surgical procedures including total cavopulmonary connection and aortic valve replacement at first complete remission, her cardiac status was significantly improved. Subsequently, she underwent cord blood stem cell transplantation at the third complete remission. She required intensive supportive care for circulatory failure as a pre-engraftment immune reaction and stage III acute graft versus host disease of the gut, but recovered from these complications. She was discharged on day 239, and remained in complete remission at 1-year post-transplantation. PMID:27599417

    We report four cases of fatal mercury vapor inhalation, a rare occurrence. The mercury vapor was released at a private home, where one of the occupants was smelting silver from dental amalgam containing an unknown amount of mercury. Within 24 hours of the incident, all occupants began having shortness of breath necessitating hospital admission. The clinical courses are briefly detailed; however, all included rapid deterioration with respiratory failure. Chest roentgenograms in all four cases were consistent with adult respiratory distress syndrome. All patients were treated with dimercaprol, a mercury chelator, but all died, with survival varying from 9 to 23 days postexposure. Autopsies were performed on all four patients. The lungs in all cases were heavy, firm, and airless. Histologic examination revealed severe diffuse alveolar damage, with variable amounts of fibrosis, conforming with acute lung injury in various stages of organization. Additional postmortem findings included acute proximal renal tubular necrosis, vacuolar hepatoxicity, and a spectrum of central nervous system alterations including multifocal ischemic necrosis, gliosis, and vasculitis.

    As the number of products containing nanomaterials increase, human exposure to nanoparticles (NPs) is unavoidable. Presently, few studies focus on the potential long-term consequences of developmental NP exposure. In this study, zebrafish embryos were acutely exposed to three gold NPs that possess functional groups with differing surface charge. Embryos were exposed to 50 μg/mL of 1.5 nm gold nanoparticles (AuNPs) possessing negatively charged 2-mercaptoethanesulfonic acid (MES) or neutral 2-(2-(2-mercaptoethoxy)ethoxy)ethanol (MEEE) ligands or 10 μg/mL of the AuNPs possessing positively charged trimethylammoniumethanethiol (TMAT). Both MES- and TMAT-AuNP exposed embryos exhibited hypo-locomotor activity, while those exposed to MEEE-AuNPs did not. A subset of embryos that were exposed to 1.5 nm MES- and TMAT-AuNPs during development from 6–120 hours post fertilization were raised to adulthood. Behavioral abnormalities and the number of survivors into adulthood were evaluated at 122 days post fertilization. We found that both treatments induced abnormal startle behavior following a tap stimulus. However, the MES-AuNPs exposed group also exhibited abnormal adult behavior in the light and had a lower survivorship into adulthood. This study demonstrates that acute, developmental exposure to 1.5 nm MES- and TMAT- AuNPs, two NPs differing only in the functional group, affects larval behavior, with behavioral effects persisting into adulthood.

    Accidental radiation exposure and the threat of deliberate radiation exposure have been in the news and are a public health concern. Experience with acute radiation sickness has been gathered from atomic blast survivors of Hiroshima and Nagasaki and from civilian nuclear accidents as well as experience gained during the development of radiation therapy for cancer. This paper reviews the medical treatment reports relevant to acute radiation sickness among the survivors of atomic weapons at Hiroshima and Nagasaki, among the victims of Chernobyl, and the two cases described so far from the Fukushima Dai-Ichi disaster. The data supporting the use of hematopoietic stem cell transplantation and the new efforts to expand stem cell populations ex vivo for infusion to treat bone marrow failure are reviewed. Hematopoietic stem cells derived from bone marrow or blood have a broad ability to repair and replace radiation induced damaged blood and immune cell production and may promote blood vessel formation and tissue repair. Additionally, a constituent of bone marrow-derived, adult pluripotent stem cells, very small embryonic like stem cells, are highly resistant to ionizing radiation and appear capable of regenerating radiation damaged tissue including skin, gut and lung.

    In the majority of cases of bipolar disorder, manic episodes are usually brief and typically responsive to currently available psychopharmacological agents. In contrast, depressive manifestations are more prevalent and persistent, and can present as major depressive/mixed episodes or residual interepisode symptoms. The depressive phase is often associated with other neuropsychiatric conditions, such as anxiety spectrum disorders, substance use disorders, stressor-related disorders, and eating disorders. It is viewed as a systemic disease with associated ailments such as metabolic syndrome, diabetes mellitus, and cardiovascular disease. There is an increased rate of mortality not only from suicide, but also from concomitant physical illness. This scenario is made worse by the fact that depressive symptoms, which represent the main disease burden, are often refractory to existing psychotropic drugs. As such, there is a pressing need for novel agents that are efficacious in acute depressive exacerbations, and also have applicable value in preventing recurrent episodes. The rationale of the present review is to delineate the pharmacotherapy of the depressive phase of bipolar disorder with medications for which there is evidence in the form of observational, open-label, or double-blind randomized controlled studies. In the treatment of acute bipolar depression in adults, a comprehensive appraisal of the extant literature reveals that among mood stabilizers, the most robust proof of efficacy exists for divalproex sodium; while atypical antipsychotics, which include olanzapine, quetiapine, lurasidone, and cariprazine, are also effective, as demonstrated in controlled trials.

    Adult patients with acute lymphoblastic leukemia who relapse after frontline therapy have extremely poor outcomes despite advances in chemotherapy and hematopoietic stem cell transplantation. Blinatumomab is a first-in-class bispecific T-cell engager that links T cells to tumor cells leading to T-cell activation and tumor cell lysis. In December 2014, the Food and Drug Administration approved blinatumomab for treatment of relapsed or refractory Philadelphia chromosome-negative precursor B-cell acute lymphoblastic leukemia. In a phase II trial, blinatumomab produced response rates of 43%, and 40% of patients achieving a complete remission proceeded to hematopoietic stem cell transplantation. Early use of blinatumomab was complicated with adverse effects, including cytokine release syndrome and neurotoxicity. Management strategies, including dexamethasone premedication and 2-step dose escalation during the first cycle of blinatumomab, have decreased the incidence and severity of these adverse effects. Blinatumomab currently is being studied for other B-cell malignancies and has the potential to benefit many patients with CD19+ malignancies in the future. PMID:27521320

    Bee pollen is given to children by mothers in order to strengthen their immune systems. There are no studies related with the side effects of bee polen in the literature. In this article, the literature was reviewed by presenting a case of allergic eosinophilic gastropathy related with bee polen. A 5-year old child was admitted due to abdominal pain. Edema was detected on the eyelids and pretibial region. In laboratory investigations, pathology was not detected in terms of hepatic and renal causes that would explain the protein loss of the patient diagnosed with hypoproteinemia and hypoalbuminemia. Urticaria was detected during the follow-up visit. When the history of the patient was deepened, it was learned that bee pollen was given to the patient every day. The total eosinophil count was found to be 1 800/mm(3). Allergic gastroenteropathy was considered because of hypereosinophilia and severe abdominal pain and endoscopy was performed. Biopsy revealed abundant eosinophils in the whole gastric mucosa. A diagnosis of allergic eosinophilic gastropathy was made. Bee polen was discontinued. Abdominal pain and edema disappeared in five days. Four weeks later, the levels of serum albumin and total eosinophil returned to normal. PMID:26568697

    Background: Eosinophilic oesophagitis is a rarely diagnosed condition involving eosinophil infiltration of the oesophageal mucosa and creating significant symptoms of dysphagia. Failure to diagnose this disorder relates to reluctance to biopsy an apparently normal oesophagus. This is essential for histological diagnosis. To date, treatment success has been achieved only with corticosteroids. We describe here the use of an eosinophil stabilising agent Montelukast for the symptomatic relief of these patients. Patients and methods: Twelve patients have been identified with this condition in our unit since 1995, after thorough investigation of their dysphagia. We commenced eight of these patients on the leukotriene receptor antagonist Montelukast to symptomatically improve their swallowing while avoiding the use of long term corticosteroids. Results: Many of these patients had been previously misdiagnosed, and therefore inappropriately and unsuccessfully treated for an extensive period prior to referral to our unit. All patients were unresponsive to acid suppression therapy alone but showed improvement in their swallowing on Montelukast. Six of eight reported complete subjective improvement, five patients remaining completely asymptomatic on a maintenance regimen. Conclusions: Eosinophilic oesophagitis is a disease that is often misdiagnosed due to lack of awareness and reluctance of clinicians to biopsy an apparently normal oesophagus in dysphagic patients, and therefore obtain a histological diagnosis. Investigation of these patients adds further evidence to this condition being a separate pathological state from gastro-oesophageal reflux and eosinophilic enteritis. Montelukast has been found to be of significant help in the symptomatic control of these patients while avoiding long term corticosteroids use. PMID:12524397

    In this review, we consider the role played by eosinophilic leukocytes in the pathogenesis and pathophysiology of respiratory virus infection. The vast majority of the available information on this topic focuses on respiratory syncytial virus (RSV; Family Paramyxoviridae, genus Pneumovirus), an important pediatric pathogen that infects infants worldwide. There is no vaccine currently available for RSV. A formalininactivated RSV vaccine used in a trial in the 1960s elicited immunopathology in response to natural RSV infection; this has been modeled experimentally, primarily in inbred mice and cotton rats. Eosinophils are recruited to the lung tissue in response to formalin-inactivated RSV vaccine antigens in humans and in experimental models, but they may or may not be involved in promoting the severe clinical sequelae observed. Pulmonary eosinophilia elicited in response to primary RSV infection has also been explored; this response is particularly evident in the youngest human infants and in neonatal mouse models. Although pulmonary eosinophilia is nearly always perceived in a negative light, the specific role played by virus-elicited eosinophils - negative, positive or neutral bystander - remain unclear. Lastly, we consider the data that focus on the role of eosinophils in promoting virus clearance and antiviral host defense, and conclude with a recent study that explores the role of eosinophils themselves as targets of virus infection.

    Genetic mutations on signaling pathways are found in patients with T-cell acute lymphoblastic leukemia (T-ALL) and act as markers of high-risk leukemia. Mutations in dynamin 2 (DNM2) have been reported in T-ALL, particularly in early T-cell precursor-ALL. In the present study, DNM2 mutations were screened by sequencing DNM2 exons obtained by polymerase chain reaction amplification and gel purification in adult T-ALL patients. A total of 4 novel DNM2 mutations were identified in adult T-ALL patients, with a mutation rate of 9.5%, and the DNM2 mutations were found to co-exist with NOTCH1 and PHD finger protein 6, and were also associated with high-risk leukemia. A high rate of silent mutation was also found in the patients, but no significant association was found between the silent mutations and patients' clinical features. The present findings suggested the DNM2 mutations may be involved in the oncogenesis of T-ALL.

    In adult patients with acute lymphoblastic leukemia (ALL), Central Nervous System (CNS) involvement is associated with a very poor prognosis. The diagnostic assessment of this condition relies on the use of neuroradiology, conventional cytology (CC) and flow cytometry (FCM). Among these approaches, which is the gold standard it is still a matter of debate. Neuroradiology and CC have a limited sensitivity with a higher rate of false negative results. FCM demonstrated a superior sensitivity over CC, particularly when low levels of CNS infiltrating cells are present. Although prospective studies of a large series of patients are still awaited, a positive finding by FCM appears to anticipate an adverse outcome even if CC shows no infiltration. Current strategies for adult ALL CNS-directed prophylaxis or therapy involve systemic and intrathecal chemotherapy and radiation therapy. An early and frequent intrathecal injection of cytostatic combined with systemic chemotherapy is the most effective strategy to reduce the frequency of CNS involvement. In patients with CNS overt ALL, at diagnosis or upon relapse, allogeneic hematopoietic stem cell transplantation might be considered. This review discusses risk factors, diagnostic techniques for identification of CNS infiltration and modalities of prophylaxis and therapy to manage it. PMID:25408861

    Although allogeneic hematopoietic stem cell transplantation from an HLA-matched sibling donor (MSD) is a potentially curative post-remission treatment for adults with acute myeloid leukemia (AML) in their first CR, transplant-related morbidity and mortality remains a major drawback. We retrospectively compared the outcomes of patients who underwent autologous peripheral blood stem cell transplantation (auto-PBSCT; n=375) with those who underwent allogeneic bone marrow transplantation (allo-BMT; n=521) and allo-PBSCT (n=380) from MSDs for adults with AML/CR1, in which propensity score models were used to adjust selection biases among patients, primary physicians and institutions to overcome ambiguity in the patients' background information. Both the multivariate analysis and propensity score models indicated that the leukemia-free survival rate of auto-PBSCT was not significantly different from that of allo-BMT (hazard ratio (HR), 1.23; 95% confidence interval (CI), 0.92 to 1.66; P=0.16) and allo-PBSCT (HR, 1.13; 95% CI, 0.85-1.51; P=0.40). The current results suggest that auto-PBSCT remains a promising alternative treatment for patients with AML/CR1 in the absence of an available MSD. PMID:26808566

    At the intersection between children and older adults, the care of adolescent and young adult (AYA) patients with acute lymphoblastic leukemia (ALL) poses unique challenges and issues beyond those faced by other age groups. Although the survival of AYA patients is inferior to younger children, growing evidence suggests that AYA patients have improved outcomes, with disease-free survival rates of 60% to 70%, when treated with pediatric-based approaches. A holistic approach, incorporating a multidisciplinary team, is a key component of successful treatment of these AYA patients. With the appropriate support and management of toxicities during and following treatment, these regimens are well tolerated in the AYA population. Even with the significant progress that has been made during the last decade, patients with persistence of minimal residual disease (MRD) during intensive therapy still have a poor prognosis. With new insights into disease pathogenesis in AYA ALL and the availability of disease-specific kinase inhibitors and novel targeted antibodies, future studies will focus on individualized therapy to eradicate MRD and result in further improvements in survival. This case-based review will discuss the biology, pharmacology, and psychosocial aspects of AYA patients with ALL, highlighting our current approach to the management of these unique patients.

    Background A convergence of technological breakthroughs in the past decade has facilitated the development of rapid screening tools for biomarkers of toxicant exposure and effect. Platforms using the whole adult organism to evaluate the genome-wide response to toxicants are especially attractive. Recent work demonstrates the feasibility of this approach in vertebrates using the experimentally robust zebrafish model. In the present study, we evaluated gene expression changes in whole adult male zebrafish following an acute 24 hr high dose exposure to three metals with known human health risks. Male adult zebrafish were exposed to nickel chloride, cobalt chloride or sodium dichromate concentrations corresponding to their respective 96 hr LC20, LC40 and LC60. Histopathology was performed on a subset of metal-exposed zebrafish to phenotypically anchor transcriptional changes associated with each metal. Results Comparative analysis identified subsets of differentially expressed transcripts both overlapping and unique to each metal. Application of gene ontology (GO) and transcription factor (TF) enrichment algorithms revealed a number of key biological processes perturbed by metal poisonings and the master transcriptional regulators mediating gene expression changes. Metal poisoning differentially activated biological processes associated with ribosome biogenesis, proteosomal degradation, and p53 signaling cascades, while repressing oxygen-generating pathways associated with amino acid and lipid metabolism. Despite appreciable effects on gene regulation, nickel poisoning did not induce any morphological alterations in male zebrafish organs and tissues. Histopathological effects of cobalt remained confined to the olfactory system, while chromium targeted the gills, pharynx, and intestinal mucosa. A number of enriched transcription factors mediated the observed gene response to metal poisoning, including known targets such as p53, HIF1α, and the myc oncogene, and novel

    We aim to evaluate the incidence and clinical manifestations of sensorineural hearing loss (SNHL) in adult patients with acute otitis media (AOM). Seventy-five patients (age > 18 years; 83 ears) diagnosed with AOM between January 2008 and March 2011 at our clinic were enroled and retrospectively reviewed. We detected audiometrically confirmed SNHL during the course of AOM in eight patients. The clinical course, treatment, and audiometric final outcome of each case were reviewed. SNHL was associated with AOM in 8 out of 83 ears (9.3%). The mean age of patients was 57.5 years, and the mean follow-up period was 21.1 months (range 0.6-46.3 months). The most common symptom was tinnitus. Mean bone conduction hearing threshold was 39.5 dB in pure tone audiometry. All patients showed high-frequency HL, and three showed pan-frequency HL. All patients were treated with oral antibiotics at the initial visit. Seven ears were treated with a combination of oral steroids. Myringotomy was also performed. Seven of eight patients showed improvement; however, 8 kHz thresholds were not improved. This suggested that the inflammation spread through the round window. The mean duration of recovery was 18.6 days. SNHL associated with AOM in adult patients occurs during the early phases of the disease course. High-frequency hearing was commonly affected and was well treated with oral antibiotics, myringotomy, and steroid therapy. Audiometry can be helpful for treating adult patients with AOM. Active treatment, including myringotomy, should be performed during the early phase, if SNHL is suspected. PMID:23990061

The study was performed in 423 younger adults with Philadelphia chromosome-negative ALL in first remission (265 B-cell precursor [BCP] and 158 T-cell ALL), with cumulative incidence of relapse (CIR) as the primary end point. In addition to conventional risk factors, the most frequent currently available genetic alterations were included in the analysis. A higher specific hazard of relapse was independently associated with postinduction MRD level ≥10(-4) and unfavorable genetic characteristics (ie, MLL gene rearrangement or focal IKZF1 gene deletion in BCP-ALL and no NOTCH1/FBXW7 mutation and/or N/K-RAS mutation and/or PTEN gene alteration in T-cell ALL). These 2 factors allowed definition of a new risk classification that is strongly associated with higher CIR and shorter relapse-free and overall survival. These results indicate that genetic abnormalities are important predictors of outcome in adult ALL not fully recapitulated by early response to therapy. Patients included in this study were treated in the multicenter GRAALL-2003 and GRAALL-2005 trials. Both trials were registered at http://www.clinicaltrials.gov as #NCT00222027 and #NCT00327678, respectively. PMID:24740809

    Memory impairment is observed in adults with type 2 diabetes mellitus (T2DM), with further acute deficits after meal ingestion. This study explored whether postprandial oxidative stress was a contributor to these meal-induced memory deficits. Sixteen adults with T2DM (mean age, 63.5 +/- 2.1 years) who were not regularly taking high-dose antioxidant supplements were fed a high-fat meal, the same test meal with vitamins C (1000 mg) and E (800 IU) tablets, or water on 3 separate occasions. After meal ingestion, a battery of cognitive tests were administered, which included measures of delayed verbal memory, assessed at 60 and 105 minutes after meal ingestion. Relative to water consumption, the high-fat meal resulted in poorer performance at 105 minutes postingestion on measures of delayed verbal recall (word list and paragraph recall) and working memory (Digit-Span Forward). Coconsumption of antioxidant vitamins and high-fat meal prevented this meal-induced deficit such that performance on these tasks was indistinguishable from that after water intake. At the same time point, a small but significant improvement on the word-naming and color-naming components of Stroop was observed after meal ingestion, relative to water, irrespective of whether antioxidants were consumed, demonstrating the specificity of meal-induced impairments to memory function. Executive function, assessed by Trails Parts A and B, was not influenced by meal or antioxidant ingestion. In adults with T2DM, coconsumption of antioxidant vitamins minimizes meal-induced memory impairment, implicating oxidative stress as a potential contributor to these decrements. PMID:19083441

    Introduction of the specialty of acute medicine and of acute medical units (AMUs) in the UK have been associated with improvements in mortality, length of stay and flow, but there is no literature on the patient experience during the early phase of acute medical admissions. We analysed the Adult Inpatient Survey (AIPS) findings for short-stay unscheduled medical admissions who did not move from their first admission ward (n=3325) and therefore are likely to have been managed entirely in the AMU. We compared these with short-stay emergencies in other specialties (n=3420) and short-stay scheduled admissions (n=10,347). Scheduled admissions reported a better experience for all survey items. Scores for unscheduled admissions were worse in medical patients compared with other specialties for pain control, privacy, involvement, information, and for a number of questions relating to information on discharge. The specialty of acute medicine should work to improve future patient experience.

    Obesity is a chronic and multifactorial disease, whose prevalence is increasing in many countries. Pharmaceutical strategies for the treatment of obesity include drugs that regulate food intake, thermogenesis, fat absorption, and fat metabolism. Fenproporex is the second most commonly consumed amphetamine-based anorectic worldwide; this drug is rapidly converted in vivo into amphetamine, which is associated with neurotoxicity. In this context, the present study evaluated DNA damage parameters in the peripheral blood of young and adult rats submitted to an acute administration and chronic administration of fenproporex. In the acute administration, both young and adult rats received a single injection of fenproporex (6.25, 12.5 or 25 mg/kg i.p.) or vehicle. In the chronic administration, both young and adult rats received one daily injection of fenproporex (6.25, 12.5, or 25 mg/kg i.p.) or Tween for 14 days. 2 h after the last injection, the rats were killed by decapitation and their peripheral blood removed for evaluation of DNA damage parameters by alkaline comet assay. Our study showed that acute administration of fenproporex in young and adult rats presented higher levels of damage index and frequency in the DNA. However, chronic administration of fenproporex in young and adult rats did not alter the levels of DNA damage in both parameters of comet assay. The present findings showed that acute administration of fenproporex promoted damage in DNA, in both young and adult rats. Our results are consistent with other reports which showed that other amphetamine-derived drugs also caused DNA damage. We suggest that the activation of an efficient DNA repair mechanism may occur after chronic exposition to fenproporex. Our results are consistent with other reports that showed some amphetamine-derived drugs also caused DNA damage. PMID:23636618

    Norovirus (NoV) infection is the most common cause of nonbacterial acute gastroenteritis, which affects both adults and children. However, the molecular epidemiology of NoV in adults with acute gastroenteritis in China has not been investigated extensively. In this study, we investigated the occurrence of NoV infections and analyzed the genetic diversity of NoV in adults with acute gastroenteritis in Huzhou, China. A total of 796 fecal samples were collected from outpatients (≥16 years of age) between March 2013 and February 2014. Real-time RT-PCR was performed to detect NoV genogroups I (GI) and II (GII). For genotyping, the capsid and RNA-dependent RNA polymerase (RdRp) genes were partially amplified and sequenced for phylogenetic analysis. NoVs were detected in 26.51% (211/796) of the specimens, with GII being predominant, representing 96.20% of the NoV infections. At least nine genotypes were identified among GI and GII specimens, including GI.P2/GI.2, GI.P3/GI.3, GI.P4/GI.4, GII.Pe/GII.4 Sydney_2012, GII.P12/GII.3, GII.P7/GII.6, GII.P16/GII.13, GII.Pe, and GII.Pg (RdRp only). This is the first report of a GII.P16/GII.13 recombinant virus in adults in China. GII.Pe/GII.4 Sydney_2012 was the most prevalent genotype and the only GII.4 variant identified during the study period. Our findings suggested that NoV was a common causative agent of acute gastroenteritis in adults in Huzhou, China. During the study period, the NoVs circulating in adults in Huzhou were predominantly GII.4 Sydney_2012 variants and GII NoV recombinants.

    Eosinophilic esophagitis (EoE) is a chronic and progressive immune-mediated condition defined by symptoms of esophageal dysfunction and dense eosinophilic infiltration of the esophageal mucosa. Therapies consist of anti-eosinophilic medications and specialized diets aimed to decrease the progression of EoE and alleviate its symptoms, namely, dysphagia and food impaction. Assessing response to therapy remains challenging, as treatment end points are not well defined and currently consist of clinical, histologic, and endoscopic features. Newer validated measures may help standardize treatment end points. Emerging data support the use of maintenance therapy, which may reduce disease progression. Optimal dosages, delivery techniques, and duration of treatment need to be determined. When features of fibrostenosis develop, esophageal dilation is a safe and effective adjunctive strategy for improving symptoms. In EoE cases refractory to conventional treatments, newer therapies targeting inflammatory mediators and cytokines are on the horizon. PMID:27695356

    Eosinophilic gastroenteritis (EG) is an inflammation of the digestive tract that is characterized by eosinophilic infiltration. There are no specific symptoms, and are related to the layer in which eosinophilic infiltration is observed. A 69-year-old Japanese man presented to our hospital with a history of general malaise, diarrhea, and dysgeusia. Esophagogastroduodenoscopy showed reddish elevated lesions that were edematous all over the gastric mucosa. In addition, three tumors were also observed. The biopsies of the reddish elevated mucosa revealed eosinophilic infiltration and tubular adenocarcinoma from the tumors. Colonoscopy showed abnormal reddish elevated mucosa. The biopsies from the reddish elevated mucosa showed eosinophilic infiltration. From the abdominal contrast computed tomography scan, tumor stain was seen in the anterior wall of the gastric body. No ascites, intestinal wall thickening, or lymph node swelling were found. A slight elevation in the serum immunoglobulin E (IgE), 480 IU/ml, was found from the laboratory test results; other laboratory results were within normal limits including the number of peripheral eosinophils. No specific allergen was found from the multiple antigen simultaneous test and from the skin patch test. The parasitic immunodiagnosis was negative. He was diagnosed with EG associated with gastric cancer and underwent total gastrectomy, regional lymph node dissection with reconstruction by a Roux-en-Y method. He was prescribed prednisolone after the operation and showed a good clinical response. There are many case reports on EG, but none of them were associated with cancer. We encountered a case of EG associated with multiple gastric cancer; the patient underwent total gastrectomy.

    IL-5 is crucial in the pathogenesis and evolution of eosinophilic asthma. Mepolizumab is a high-affinity humanized monoclonal antibody of the IgG1/k subtype that inhibits the binding of IL-5 to its receptor expressed on eosinophils, thereby inducing significant reduction in eosinophil circulation, as well as asthma exacerbations and corticosteroid treatment. This review deals with the currently available studies of mepolizumab in the treatment of patients with severe eosinophilic asthma.

    Neonatal rats have a high intestinal lactase activity, which declines around weaning. Yet, the effects of lactose-containing products are often studied in adult animals. This report is on the residual, post-weaning lactase activity and on the short- and long-term effects of lactose exposure in adult rats. Acutely, the postprandial plasma response to increasing doses of lactose was studied, and chronically, the effects of a 30% lactose diet fed from postnatal (PN) Day 15 onwards were evaluated. Intestinal lactase activity, as assessed both in vivo and in vitro, was compared between both test methods and diet groups (lactose vs. control). A 50%-75% decreased digestive capability towards lactose was observed from weaning into adulthood. Instillation of lactose in adult rats showed disproportionally low increases in plasma glucose levels and did not elicit an insulin response. However, gavages comprising maltodextrin gave rise to significant plasma glucose and insulin responses, indicative of a bias of the adult GI tract to digest glucose polymers. Despite the residual intestinal lactase activity shown, a 30% lactose diet was poorly digested by adult rats: the lactose diet rendered the animals less heavy and virtually devoid of body fat, whereas their cecum tripled in size, suggesting an increased bacterial fermentation. The observed acute and chronic effects of lactose exposure in adult rats cannot be explained by the residual intestinal lactase activity assessed.

    The aim of this study was to assess the impact of recurrent acute chest syndrome (ACS) episodes on the lung function of young adults with sickle cell disease (SCD). Our prospective study included 80 SCD adults [26 with recurrent acute chest syndrome (ACS)] and 80 ethnically matched controls aged between 18 and 28 years. Lung function (spirometry and lung volumes) was measured and the results were expressed as the percentage predicted for height. Bronchial hyperresponsiveness (BHR) was assessed by the response to either a bronchodilator or an exercise challenge. The adults with recurrent ACS (two or more ACS episodes) had lower median forced vital capacity (74 vs. 83%, p = 0.03), forced expiratory volume in 1 s (79 vs. 90%, p < 0.03), and total lung capacity (69 vs. 81%, p = 0.04) than SCD adults who had one or no ACS episodes. The greater the number of ACS episodes, the greater the reduction in lung function (p = 0.001). The adults with SCD had lower median forced vital capacity (81 vs. 106%), forced expiratory volume in 1 s (85 vs. 107%), and total lung capacity (80 vs. 87%) than the controls (p < 0.001). Similar numbers in each group had BHR (p = 0.2). The prevalence of restrictive ventilatory defect in the patients with SCD was almost double that of the controls (p = 0.004). Young adults with SCD have worse lung function than ethnically matched controls, particularly if they have suffered recurrent ACS episodes.

    Eosinophilic esophagitis (EE) is a relatively new, chronic, TH 2-type allergic inflammation of the esophagus. EE occurs more frequently in men. Allergic diseases such as asthma or atopic dermatitis are present in 50-70 % of patients or their relatives. In adults, the most common presenting symptom of EE is dysphagia, with or without food bolus impaction. Endoscopic findings of EE include mucosal furrows, corrugated or concentric rings or ridges in the esophagus ("feline esophagus"), with or without tiny whitish exudates. The diagnosis is confirmed by the observation of high counts of eosinophils in the esophageal epithelium (at least 24 /HPF). The cornerstones of medical therapy are either topical or systemic corticosteroids. Additional therapies included leukotriene receptor antagonists (montelukast) and IL-5 blockers (Mepolizumab). Complications of EE such as esophageal strictures should be carefully dilated using either bougies or a balloon. Currently it is still not known whether the late complications of EE can be prevented by the use of anti-inflammatory agents and this can only be demonstrated through further long-term follow-up studies.

    2014-01-01

    Eosinophilic esophagitis, an increasingly recognized chronic inflammatory disorder isolated to the esophagus, is triggered by an abnormal allergic response to dietary antigens. Current treatment includes swallowed topical steroids and dietary modification, which aim to resolve symptoms and prevent long-term complications such as formation of strictures. The dietary approach has become more widely accepted because long-term steroid therapy is associated with potential risks. Dietary treatment includes elemental and elimination diets. An exclusive elemental diet, which requires replacement of all intact protein with amino acid-based formula, offers the best response of all available therapies, with remission in up to 96% of subjects proving it to be superior to all other available therapies including topical steroids. However, compliance with this approach is challenging because of poor taste and monotony. The high cost of formula and the associated psychosocial problems are additional drawbacks of this approach. Empiric and allergy test-directed elimination diets have gained popularity given that elimination of a limited number of foods is much easier and as such is more readily acceptable. There is a growing body of literature supporting this type of therapy in both children and adults. This paper reviews the evidence for all types of dietary therapy in eosinophilic esophagitis.

    Eosinophils play a major pathologic role in the pathogenesis of diverse inflammatory diseases including chronic rhinosinusitis (CRS). Dysregulated production of prostaglandin (PG), particularly PGD2, is considered to be an important contributing factor to eosinophilic inflammation in CRS primarily through proinflammatory and chemotactic effects on eosinophils. Here, we provide evidence that PGD2 can promote eosinophilic inflammation through a suppression of Natural killer (NK) cell effector function and NK cell-mediated eosinophil regulation. Eosinophil apoptosis mediated by NK cells was significantly decreased in CRS patients compared with healthy controls. This decrease was associated with NK cell dysfunction and eosinophilic inflammation. Tissue eosinophils were positively correlated with blood eosinophils in CRS patients. In a murine model of CRS, NK cell depletion caused an exacerbation of blood eosinophilia and eosinophilic inflammation in the sinonasal tissue. PGD2 and its metabolite, but not PGE2 and a panel of cytokines including TGF-β, were increased in CRS patients compared with controls. Effector functions of NK cells were potently suppressed by PGD2-dependent, rather than PGE2-dependent, pathway in controls and CRS patients. Thus, our results suggest decreased NK cell-mediated eosinophil regulation, possibly through an increased level of PGD2, as a previously unrecognized link between PG dysregulation and eosinophilic inflammation in CRS.

    Cadmium is a heavy metal that can accumulate to toxic levels in the environment leading to detrimental effects in animals and humans including kidney, liver and lung injuries. Using a transcriptomics approach, genes and cellular pathways affected by a low dose of cadmium were investigated. Adult largemouth bass were intraperitoneally injected with 20μg/kg of cadmium chloride (mean exposure level - 2.6μg of cadmium per fish) and microarray analyses were conducted in the liver and testis 48h after injection. Transcriptomic profiles identified in response to cadmium exposure were tissue-specific with the most differential expression changes found in the liver tissues, which also contained much higher levels of cadmium than the testis. Acute exposure to a low dose of cadmium induced oxidative stress response and oxidative damage pathways in the liver. The mRNA levels of antioxidants such as catalase increased and numerous transcripts related to DNA damage and DNA repair were significantly altered. Hepatic mRNA levels of metallothionein, a molecular marker of metal exposure, did not increase significantly after 48h exposure. Carbohydrate metabolic pathways were also disrupted with hepatic transcripts such as UDP-glucose, pyrophosphorylase 2, and sorbitol dehydrogenase highly induced. Both tissues exhibited a disruption of steroid signaling pathways. In the testis, estrogen receptor beta and transcripts linked to cholesterol metabolism were suppressed. On the contrary, genes involved in cholesterol metabolism were highly increased in the liver including genes encoding for the rate limiting steroidogenic acute regulatory protein and the catalytic enzyme 7-dehydrocholesterol reductase. Integration of the transcriptomic data using functional enrichment analyses revealed a number of enriched gene networks associated with previously reported adverse outcomes of cadmium exposure such as liver toxicity and impaired reproduction.

    Background and Objective: Acute coronary syndrome (ACS) is one of the leading cause of morbidity and mortality worldwide. It is relatively uncommon in young adults as compared to the older population. Our objective was to assess the prevalence, demographic distribution, and risk factors for acute coronary syndrome (ACS) in patients less than 45 years of age admitted to a Malaysian tertiary care centre. Methods: This is a cross-sectional, retrospective, and single centre study with random sampling of the patients admitted for ACS to hospital from January 2005 to December 2013. Data were collected and analyzed. Patients less than 45 years of age were compared with patients more than 45 years of age. Result: A total of 628 patients were included in the study and with the prevalence of young ACS was 6.1% and mean age of 39±6 years. All the young ACS patients were diagnosed with unstable angina and non-ST elevation myocardial infarction (NSTEMI). Tobacco smoking and family history of coronary artery disease (CAD) were more frequent in young ACS. 59.5% of the young ACS patients were smokers, while 37.8% and 51.4% of them were found to suffer from diabetes mellitus and hypertension respectively. Tobacco smoking, diabetes mellitus, and hypertension had shown significant association with the onset of young ACS (p ≤ 0.05). Conclusion: Three leading risk factors (tobacco smoking, diabetes mellitus, and hypertension) had been shown to be significantly associated with the onset of young ACS. Thus, it is important to identify this cohort and implement aggressive measures in tackling the risk factors in order to prevent or halt the development of coronary artery disease.

    Caffeine is a commonly used stimulant thought to have ergogenic properties. Most studies on the ergogenic effects of caffeine have been conducted in athletes. The purpose of this study was to test the hypothesis that caffeine reduces ratings of perceived exertion and increases liking of physical activity in sedentary adults. Participants completed treadmill walking at 60% to 70% of their maximal heart rate at baseline and for 6 subsequent visits, during which half of the participants were given caffeine (3 mg/kg) and half given placebo in a sports drink vehicle. To investigate the potential synergistic effects of acute and chronic caffeine on self-determined exercise duration, participants were rerandomized to either the same or different condition for the last visit, creating 4 chronic/acute treatment groups (placebo/placebo, placebo/caffeine, caffeine/placebo, caffeine/caffeine). Participants rated how much they liked the activity and perceived exertion at each visit. There was a main effect of time on liking of physical activity, with liking increasing over time and an interaction of sex and caffeine treatment on liking, with liking of activity increasing in female participants treated with caffeine, but not with placebo. There was no effect of caffeine on ratings of perceived exertion. Individuals who received caffeine on the final test day exercised for significantly longer than those who received placebo. These data suggest that repeated exposure to physical activity significantly increases liking of exercise and reduces ratings of perceived exertion and that caffeine does little to further modify these effects.

    Background and Objective: Acute coronary syndrome (ACS) is one of the leading cause of morbidity and mortality worldwide. It is relatively uncommon in young adults as compared to the older population. Our objective was to assess the prevalence, demographic distribution, and risk factors for acute coronary syndrome (ACS) in patients less than 45 years of age admitted to a Malaysian tertiary care centre. Methods: This is a cross-sectional, retrospective, and single centre study with random sampling of the patients admitted for ACS to hospital from January 2005 to December 2013. Data were collected and analyzed. Patients less than 45 years of age were compared with patients more than 45 years of age. Result: A total of 628 patients were included in the study and with the prevalence of young ACS was 6.1% and mean age of 39±6 years. All the young ACS patients were diagnosed with unstable angina and non-ST elevation myocardial infarction (NSTEMI). Tobacco smoking and family history of coronary artery disease (CAD) were more frequent in young ACS. 59.5% of the young ACS patients were smokers, while 37.8% and 51.4% of them were found to suffer from diabetes mellitus and hypertension respectively.

    The neurotransmitter serotonin (5-HT) is involved in mood disorder aetiology and it has been reported that (organophosphate) OP exposure affects 5-HT turnover. The aim of this study was to elucidate the mechanism underlying OP effects on the adult 5-HT system. First, acute in vivo administration of the OP diazinon (0, 1.3, 13 or 39 mg/kg i.p.) to male Hooded Lister rats inhibited the activity of the cholinergic enzyme acetylcholinesterase in blood and in the hippocampus, dorsal raphe nucleus (DRN), striatum and prefrontal cortex. Diazinon-induced cholinesterase inhibition was greatest in the DRN, the brain's major source of 5-HT neurones. Second, acute in vivo diazinon exposure (0 or 39 mg/kg i.p.) increased the basal firing rate of DRN neurones measured ex vivo in brain slices. The excitatory responses of DRN neurones to α1-adrenoceptor or AMPA/kainate receptor activation were not affected by in vivo diazinon exposure but the inhibitory response to 5-HT was attenuated, indicating 5-HT1A autoreceptor down-regulation. Finally, direct application of the diazinon metabolite diazinon oxon to naive rat brain slices increased the firing rate of DRN 5-HT neurones, as did chlorpyrifos-oxon, indicating the effect was not unique to diazinon. The oxon-induced augmentation of firing was blocked by the nicotinic acetylcholine receptor antagonist mecamylamine and the AMPA/kainate glutamate receptor antagonist DNQX. Together these data indicate that 1) acute OP exposure inhibits DRN cholinesterase, leading to acetylcholine accumulation, 2) the acetylcholine activates nicotinic receptors on 5-HT neurones and also on glutamatergic neurones, thus releasing glutamate and activating 5-HT neuronal AMPA/kainate receptors 3) the increase in 5-HT neuronal activity, and resulting 5-HT release, may lead to 5-HT1A autoreceptor down-regulation. This mechanism may be involved in the reported increase in risk of developing anxiety and depression following occupational OP exposure. PMID

    Synopsis The gastrointestinal tract provides an intriguing organ for considering the eosinophil’s role in health and disease. The normal gastrointestinal (GI) tract, except for the esophagus, is populated by eosinophils that are present throughout the mucosa in varying numbers. This latter fact raises the possibility that eosinophils participate in innate mechanisms of defense. In contrast, a number of clinical studies provide a wealth of data that associates increased numbers of eosinophils with inflammatory GI diseases; these findings prompt concerns that eosinophils may have a deleterious effect on the gut. In this article we present clinical features of 4 disease processes that have been associated with eosinophilia and suggest areas requiring investigation as to their clinical significance and scientific relevance.

    Background and Purpose Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disorder that predominantly affects children. Previous studies have mostly involved children in Western developed countries. Methods This study retrospectively reviewed the clinical profiles of ADEM in adult Chinese patients. Results ADEM occurred during summer and autumn in about two-thirds of the 42 included patients. Prior infection was found in five patients and no preimmunization was recorded. The most frequent clinical presentations were alterations in consciousness (79%) and behavior changes (69%), followed by motor deficits (64%) and fever (50%). About one-quarter (26%) of the patients showed positive results for oligoclonal bands, and about half of them exhibited increases in the IgG index and 24-hour IgG synthesis rate. Magnetic resonance imaging showed white- and gray-matter lesions in 83% and 23% of the patients, respectively. Steroids were the main treatment, and full recovery occurred in 62% of the patients, with residual focal neurological deficits recorded in a few patients. After a mean follow-up period of 3.4 years, two patients exhibited recurrence and one patient exhibited a multiphasic course. One patient was diagnosed with multiple sclerosis (MS). Conclusions With the exception of the seasonal distribution pattern and prior vaccine rate, the clinical profiles of ADEM in adult Chinese patients are similar to those in pediatric populations. No specific markers are available for distinguishing ADEM from MS at the initial presentation. Careful clinical evaluations, cerebrospinal fluid measurements, and neuroradiological examinations with long-term follow-up will aid the correct diagnosis of ADEM. PMID:27449911

    Malnutrition below 5 years remains a global health issue. Severe acute malnutrition (SAM) presents in childhood as oedematous (kwashiorkor) or nonoedematous (marasmic) forms, with unknown long-term cardiovascular consequences. We hypothesized that cardiovascular structure and function would be poorer in SAM survivors than unexposed controls. We studied 116 adult SAM survivors, 54 after marasmus, 62 kwashiorkor, and 45 age/sex/body mass index-matched community controls who had standardized anthropometry, blood pressure, echocardiography, and arterial tonometry performed. Left ventricular indices and outflow tract diameter, carotid parameters, and pulse wave velocity were measured, with systemic vascular resistance calculated. All were expressed as SD scores. Mean (SD) age was 28.8±7.8 years (55% men). Adjusting for age, sex, height, and weight, SAM survivors had mean (SE) reductions for left ventricular outflow tract diameter of 0.67 (0.16; P<0.001), stroke volume 0.44 (0.17; P=0.009), cardiac output 0.5 (0.16; P=0.001), and pulse wave velocity 0.32 (0.15; P=0.03) compared with controls but higher diastolic blood pressures (by 4.3; 1.2-7.3 mm Hg; P=0.007). Systemic vascular resistance was higher in marasmus and kwashiorkor survivors (30.2 [1.2] and 30.8 [1.1], respectively) than controls 25.3 (0.8), overall difference 5.5 (95% confidence interval, 2.8-8.4 mm Hg min/L; P<0.0001). No evidence of large vessel or cardiac remodeling was found, except closer relationships between these indices in former marasmic survivors. Other parameters did not differ between SAM survivor groups. We conclude that adult SAM survivors had smaller outflow tracts and cardiac output when compared with controls, yet markedly elevated peripheral resistance. Malnutrition survivors are thus likely to develop excess hypertension in later life, especially when exposed to obesity.

    In 1879 Paul Ehrlich published his technique for staining blood films and his method for differential blood cell counting using coal tar dyes and mentions the eosinophil for the first time. Eosin is a bright red synthetic dye produced by the action of bromine on fluorescein and stains basic proteins due to its acidic nature. It was discovered in 1874 by Heinrich Caro, Director of the German chemical company Badische Anilin- und Soda-Fabrik. Ehrlich introduced the term 'eosinophil' to describe cells with granules (which he called alpha-granules) having an affinity for eosin and other acid dyes. He also observed black-staining, indulinophilic, beta-granules in bone marrow-derived eosinophils, which were probably immature crystalloid granules in eosinophil myelocytes. Ehrlich described the features of the alpha-granule and the cell's distribution in various species and tissues. He speculated correctly that the alpha-granule contents were secretory products and described several causes of eosinophilia including asthma, various skin diseases, helminths and reactions to medications. However, the cell was almost certainly observed by others before Ehrlich. In 1846 Thomas Wharton Jones (1808-1891) described 'granule blood cells' in the lamprey, frog, fowl, horse, elephant and man. He 'borrowed' the term granule cell from Julius Vogel (1814-1880) who had observed similar cells in inflammatory exudates. Vogel in turn was aware of the work of the Gottlieb (Théophile) Gluge (1812-1898) who used the term 'compound inflammatory globules' to describe cells in pus and serum. Almost 20 years before Ehrlich developed his staining methods, Max Johann Sigismund Schultze (1825-1874) performed functional experiments on coarse granular cells using a warm stage microscopic technique and showed they had amoeboid movement and phagocytic abilities. Although these early investigators recognised distinct granular cells Ehrlich's use of stains was a landmark contribution, which heralded

    We compared outcomes from a single-arm study of blinatumomab in adult patients with B-precursor Ph-negative relapsed/refractory acute lymphoblastic leukemia (R/R ALL) with a historical data set from Europe and the United States. Estimates of complete remission (CR) and overall survival (OS) were weighted by the frequency distribution of prognostic factors in the blinatumomab trial. Outcomes were also compared between the trial and historical data using propensity score methods. The historical cohort included 694 patients with CR data and 1112 patients with OS data compared with 189 patients with CR and survival data in the blinatumomab trial. The weighted analysis revealed a CR rate of 24% (95% CI: 20–27%) and a median OS of 3.3 months (95% CI: 2.8–3.6) in the historical cohort compared with a CR/CRh rate of 43% (95% CI: 36–50%) and a median OS of 6.1 months (95% CI: 4.2–7.5) in the blinatumomab trial. Propensity score analysis estimated increased odds of CR/CRh (OR=2.68, 95% CI: 1.67–4.31) and improved OS (HR=0.536, 95% CI: 0.394–0.730) with blinatumomab. The analysis demonstrates the application of different study designs and statistical methods to compare novel therapies for R/R ALL with historical data. PMID:27662202

  9. Retroviral induction of acute lymphoproliferative disease and profound immunosuppression in adult C57BL/6 mice

    PubMed Central

    1985-01-01

    We have shown that a mixture of murine leukemia viruses (MuLV) causes the acute onset of lymphoproliferation and immunosuppression when injected into adult C57BL/6 mice. The ecotropic/MCF (mink cell focus- inducing) mixture of MuLV stimulates polyclonal B lymphocyte proliferation and differentiation to antibody-secreting cells. Serum Ig levels are elevated for all isotypes except IgA. The viral infection leads to a rapid decline in T lymphocyte responses to mitogens and alloantigens, as well as a decrease in helper cell activity. Specific antibody responses to both T-dependent and T-independent antigens are impaired, and the response of B lymphocytes to mitogens is abolished. The profound immunosuppression seems to be due to the MuLV-induced polyclonal activation of lymphocytes. No active suppression of normal lymphocyte responses by cells from virus-infected mice was observed. The disease induced by the LP-BM5 MuLV isolate thus seems a promising model for the study of lymphocyte activation and the mechanisms of retrovirus-induced immunosuppression. PMID:2984305

    Twenty-five adult patients with previously untreated acute non-lymphocytic leukemia (ANLL) were treated with mitoxantrone (Mto) 12 mg/m2 daily by 30 minutes intravenous (IV) infusion for 3 days and cytosine arabinoside (Ara-C) 200 mg/m2 daily by continuous infusion for 7 days, as an induction therapy. After complete remission (CR) was observed, they were given two more courses of consolidation therapy which was as Mto 12 mg/m2 daily by 30 minutes IV infusion for one day, and Ara-C 200 mg/m2 daily by 30 minutes IV infusion for 5 days. CR was obtained in 18 of 25 patients (72%). Median remission duration was 294 days and length of survival was 366 days. 11 patients (44%) are still in remission. Myelosupression developed in all patients following induction therapy, but it was not observed after consolidation therapies. Non-hematological side-effects consisted of nausea, vomiting, alopecia, stomatitis, and transient elevation in liver enzymes. Our therapeutic responses are similar to those obtained by others.

    In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors. In humans, results on the effect of acute exercise on memory are inconsistent so far. Therefore, the aim of the present study was to assess the effects of a single bout of physical exercise on memory consolidation and the underlying neuroendocrinological mechanisms in young adults. Participants encoded a list of German-Polish vocabulary before exercising for 30 minutes with either high intensity or low intensity or before a relaxing phase. Retention of the vocabulary was assessed 20 minutes after the intervention as well as 24 hours later. Serum BDNF and salivary cortisol were measured at baseline, after learning, and after the intervention. The high-intensity exercise group showed an increase in BDNF and cortisol after exercising compared to baseline. Exercise after learning did not enhance the absolute number of recalled words. Participants of the high-intensity exercise group, however, forgot less vocabulary than the relaxing group 24 hours after learning. There was no robust relationship between memory scores and the increase in BDNF and cortisol, respectively, suggesting that further parameters have to be taken into account to explain the effects of exercise on memory in humans.

    This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

    With the goal of providing guidance on the provision of optimal intensive care to adult patients with acute liver failure (ALF), this paper defines ALF and describes a protocol for appropriately diagnosing this relatively rare clinical entity and ascertaining its etiology, where possible. This paper also identifies the few known therapies that may be effective for specific causes of ALF and provides a comprehensive approach for anticipating, identifying, and managing complications. Finally, one of the more important aspects of care for patients with ALF is the determination of prognosis and, specifically, the need for liver transplantation. Prognostic tools are provided to help guide the clinician in this critical decision process. Management of patients with ALF is complex and challenging, even in centers where staff members have high levels of expertise and substantial experience. This evidence-based protocol may, therefore, assist in the delivery of optimal care to this critically ill patient population and may substantially increase the likelihood of positive outcomes.

    2014-01-01

    Adult acute lymphoblastic leukemia (ALL) is a heterogeneous disease, due to the expression of different biological and clinical risk factors, for which allogeneic stem cell transplantation (alloHSCT) is an effective consolidation therapy. The non-relapse mortality of alloHSCT remains significantly higher compared with that of conventional chemotherapy. Therefore, one of the main challenges in the care of ALL is to establish a more precise prognostic definition to select patients who could take advantage from an alloHSCT. Currently, the use of minimal residual disease following induction and early consolidation therapy has improved the prognostic accuracy in defining ALL risk class. In Philadelphia-positive ALL, the introduction of tyrosine kinase inhibitors pre and post alloHSCT appears to improve outcomes significantly and, in the absence of specially designed clinical trials, alloHSCT remains the most effective post-remission therapy. Nowadays, alloHSCT can be performed according to various modalities encompassing the use of different conditioning regimens, as well as distinct donors and stem cell source, with a significant accessibility to transplant.

    The oncogenic mechanisms underlying acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYA; 15-39 years old) remain largely elusive. Here we have searched for new oncogenes in AYA-ALL by performing RNA-seq analysis of Philadelphia chromosome (Ph)-negative AYA-ALL specimens (n = 73) with the use of a next-generation sequencer. Interestingly, insertion of D4Z4 repeats containing the DUX4 gene into the IGH locus was frequently identified in B cell AYA-ALL, leading to a high level of expression of DUX4 protein with an aberrant C terminus. A transplantation assay in mice demonstrated that expression of DUX4-IGH in pro-B cells was capable of generating B cell leukemia in vivo. DUX4 fusions were preferentially detected in the AYA generation. Our data thus show that DUX4 can become an oncogenic driver as a result of somatic chromosomal rearrangements and that AYA-ALL may be a clinical entity distinct from ALL at other ages. PMID:27019113

    Background/Aims Abdominal pain-related functional gastrointestinal disorder (AP-FGID) is common in children and adults. However, the mechanism of AP-FGID is not clearly known. Recently, micro-inflammation, especially eosinophilia in the gastrointestinal tract, was suggested in the pathophysiology of AP-FGID in adults. The aim of this study was to evaluate the association of gastric and duodenal eosinophilia with pediatric AP-FGID. Methods In total, 105 pediatric patients with AP-FGID were recruited and classified into 4 subgroups based on the Rome III criteria. Eosinophil counts in the gastric and duodenal tissues of children with AP-FGID were compared to those from normal pathology references or those of children with Helicobacter pylori infection. Tissue eosinophil counts were also compared among the 4 subtypes of AP-FGID. Results Eosinophil counts in the gastric antrum and body were significantly higher in children with AP-FGID than normal reference values. Duodenal eosinophil counts were higher in children with AP-FGID, but not significantly when compared with normal reference values. There were no significant differences in eosinophil counts of the stomach or duodenum among the 4 subtypes of AP-FGID. Eosinophils counts in the gastric antrum and body were significantly higher in children with H. pylori infection than in those with AP-FGID. Duodenal eosinophilia was prominent in cases of H. pylori infection, but not statistically significant when compared with AP-FGID. Conclusions Our study revealed that gastric eosinophilia is associated with AP-FGID in children, regardless of the subtype of functional abdominal pain. This suggests some contribution of gastrointestinal eosinophils in the development of pediatric AP-FGID. PMID:27053514

    Woodchuck hepatitis virus (WHV) is often used as surrogate to study mechanism of HBV infection. Currently, most infections are conducted using strains WHV7 or WHV8 that have very high sequence identity. This study focused on natural strain WHVNY that is more genetically distant from WHV7. Three naive adult woodchucks inoculated with WHVNY developed productive acute infection with long lasting viremia. However, only one of two woodchucks infected with WHV7 at the same multiplicity demonstrated productive liver infection. Quantification of intracellular WHV RNA and DNA replication intermediates; percentages of core antigen-positive hepatocytes; and serum relaxed circular DNA showed that strains WHVNY and WHV7 displayed comparable replication levels and capacities to induce acute infection in naive adult woodchucks. Strain WHVNY was therefore validated as valuable reagent to analyze the mechanism of hepadnavirus infection, especially in co- and super-infection settings, which required discrimination between two related virus genomes replicating in the same liver.

    The idea behind this thesis is to present how ARS and especially acute maxillary sinusitis in adults is diagnosed and treated in general practice. The study extends over many years, beginning with the first survey in 1991. Based on doctors' answers, we then investigated the diagnostic values ​​of the symptoms, signs and examinations which the doctors reported using. All patients over 18 years suspected of acute maxillary sinusitis were included consecutively and only once and, after a clinical examination with the GP, they were offered the opportunity to enter into the prospective study referred to acute CT scan and by changes in the CT, immediately referred to sinus puncture. Both examinations were conducted at Aalborg Hospital. The disease was found most frequently in younger and 2/3 were women. The reason for this gender difference is unknown. We have assessed the diagnostic values of the symptoms, objective findings and investigations ​​using 3 different reference standards: sinus puncture, microbiological diagnosis and CT scan described in three articles. In all examinations, it appeared that the usual signs and symptoms of acute maxillary sinusitis occur almost equally often and with a few exceptions in patients, with and without pus in the sinus cavities. Pain in the sinus cavities occurring in 95% of patients, and only elevated levels of CRP and ESR are significantly and independently associated with pus in the sinus cavities. This finding is surprising, because they are two nonspecific markers. CRP tested by near-patient testing has, within the investigations period, been introduced in general practice, and from 1999 the doctors also get reimbursed for performing the test. We have on this background originally defined a clinical criterion with pain over the sinuses accompanied by elevated values ​​of CRP and/or ESR giving a sensitivity of 0.82, specificity 0.57, ppv 0.68 and npv 0.74. But looking at the ROC curve we suggest that a more clinical

    The differential diagnosis for eosinophil-rich skin lesions often includes a drug reaction, allergic contact dermatitis and rarely, response to a helminth infection. However, many unrelated entities, such as infections, neoplasms and inflammatory dermatoses, can have a prominent eosinophilic infiltrate. Syphilis is classically associated with plasma cells, but other patterns of inflammation have been reported, including ulcerative, granulomatous and eosinophil-rich. Classic teaching might indicate that the presence of eosinophils argues against a diagnosis of syphilis. We present four cases of secondary syphilis with increased eosinophils, ranging from 8 to >200 eosinophils per 10 high-power fields (×400 magnification). Patient 1 had lesions on the penis and scrotum, with greater than 200 eosinophils per 10 high-power fields. Patient 2 had lesions on the back, with 150 eosinophils per 10 high-power fields. Patient 3 had lesions on the bilateral arms, with 8 eosinophils per 10 high-power fields. Patient 4 had lesions involving the anus, with 17 eosinophils per 10 high-power fields. These cases highlight that the presence of an eosinophil-rich infiltrate on skin biopsy should not exclude syphilis from the differential diagnosis.

    Curative-intent therapy leads to complete remissions in many adults with acute myeloid leukemia (AML), but relapse remains common. Numerous studies have unequivocally demonstrated that the persistence of measurable ('minimal') residual disease (MRD) at the submicroscopic level during morphologic remission identifies patients at high risk of disease recurrence and short survival. This association has provided the impetus to customize anti-leukemia therapy based on MRD data, a strategy that is now routinely pursued in acute promyelocytic leukemia (APL). While it is currently uncertain whether this approach will improve outcomes in AML other than APL, randomized studies have validated MRD-based risk-stratified treatment algorithms in acute lymphoblastic leukemia. Here, we review the available studies examining MRD-directed therapy in AML, appraise their strengths and limitations, and discuss avenues for future investigation.

    Eosinophils are now recognized as multifunctional leukocytes that provide critical homeostatic signals to maintain other immune cells and aid tissue repair. Paradoxically, eosinophils also express an armory of granule-localized toxins and hydrolases believed to contribute to pathology in inflammatory disease. How eosinophils deliver their supporting functions while avoiding self-inflicted injury is poorly understood. We have demonstrated that cystatin F (CF) is a critical survival factor for eosinophils. Eosinophils from CF null mice had reduced lifespan, reduced granularity, and disturbed granule morphology. In vitro, cysteine protease inhibitors restored granularity, demonstrating that control of cysteine protease activity by CF is critical for normal eosinophil development. CF null mice showed reduced pulmonary pathology in a model of allergic lung inflammation but also reduced ability to combat infection by the nematode Brugia malayi. These data identify CF as a "cytoprotectant" that promotes eosinophil survival and function by ensuring granule integrity. VIDEO ABSTRACT. PMID:27067058

    Stress is a potent modulator of the mammalian brain. The highly conserved stress hormone response influences many brain regions, particularly the hippocampus, a region important for memory function. The effect of acute stress on the unique population of adult neural stem/progenitor cells (NPCs) that resides in the adult hippocampus is unclear. We found that acute stress increased hippocampal cell proliferation and astrocytic fibroblast growth factor 2 (FGF2) expression. The effect of acute stress occurred independent of basolateral amygdala neural input and was mimicked by treating isolated NPCs with conditioned media from corticosterone-treated primary astrocytes. Neutralization of FGF2 revealed that astrocyte-secreted FGF2 mediated stress-hormone-induced NPC proliferation. 2 weeks, but not 2 days, after acute stress, rats also showed enhanced fear extinction memory coincident with enhanced activation of newborn neurons. Our findings suggest a beneficial role for brief stress on the hippocampus and improve understanding of the adaptive capacity of the brain. DOI:http://dx.doi.org/10.7554/eLife.00362.001.

    Objectives To determine whether over the counter cough medicines are effective for acute cough in adults. Design Systematic review of randomised controlled trials. Data sources Search of the Cochrane Acute Respiratory Infections Group specialised register, Cochrane Controlled Trials Register, Medline, Embase, and the UK Department of Health National Research Register in all languages. Included studies All randomised controlled trials that compared oral over the counter cough preparations with placebo in adults with acute cough due to upper respiratory tract infection in ambulatory settings and that had cough symptoms as an outcome. Results 15 trials involving 2166 participants met all the inclusion criteria. Antihistamines seemed to be no better than placebo. There was conflicting evidence on the effectiveness of antitussives, expectorants, antihistamine-decongestant combinations, and other drug combinations compared with placebo. Conclusion Over the counter cough medicines for acute cough cannot be recommended because there is no good evidence for their effectiveness. Even when trials had significant results, the effect sizes were small and of doubtful clinical relevance. Because of the small number of trials in each category, the results have to be interpreted cautiously. What is already know on this topicThe NHS encourages self treatment of acute self limiting illnessesOver the counter cough medicines are commonly used as first line treatment for acute coughWhat this study addsThere is little evidence for or against the effectiveness of over the counter cough medicinesAlthough cough medicines are generally well tolerated, they may be an unnecessary expenseRecommendation of over the counter cough medicines to patients is not justified by current evidence PMID:11834560

    Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adult T-cell acute lymphoblastic leukemia uniformly treated during the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. HOXA-positive patients had markedly higher rates of an early thymic precursor-like immunophenotype (40.8% versus 14.5%, P=0.0004), chemoresistance (59.3% versus 40.8%, P=0.026) and positivity for minimal residual disease (48.5% versus 23.5%, P=0.01) than the HOXA-negative group. These differences were due to particularly high frequencies of chemoresistant early thymic precursor-like acute lymphoblastic leukemia in HOXA-positive cases harboring fusion oncoproteins that transactivate HOXA. Strikingly, the presence of an early thymic precursor-like immunophenotype was associated with marked outcome differences within the HOXA-positive group (5-year overall survival 31.2% in HOXA-positive early thymic precursor versus 66.7% in HOXA-positive non-early thymic precursor, P=0.03), but not in HOXA-negative cases (5-year overall survival 74.2% in HOXA-negative early thymic precursor versus 57.2% in HOXA-negative non-early thymic precursor, P=0.44). Multivariate analysis further revealed that HOXA positivity independently affected event-free survival (P=0.053) and relapse risk (P=0.039) of chemoresistant T-cell acute lymphoblastic leukemia. These results show that the underlying mechanism of HOXA deregulation dictates the clinico-biological phenotype, and that the negative prognosis of early thymic precursor acute lymphoblastic leukemia is exclusive to HOXA-positive patients, suggesting that early treatment intensification is currently

  10. Eosinophil-derived neurotoxin: a novel biomarker for diagnosis and monitoring of asthma

    PubMed Central

    2013-01-01

    Asthma is associated with increased levels of eosinophils in tissues, body fluids, and bone marrow. Elevated levels of eosinophil-derived neurotoxin (EDN) and eosinophil cationic protein (ECP) have been noted in asthma patients. Higher levels of EDN and ECP are also associated with exacerbated asthmatic conditions. Thus, EDN, along with ECP, may aid the diagnosis and monitoring of asthma. Several groups have suggested that EDN is more useful than ECP in evaluating disease severity. This may partially be because of the recoverability of EDN (not sticky, 100% recovery rate), as ECP is a sticky and more highly charged protein. In terms of clinical utility, EDN level is a more accurate biomarker than ECP when analyzing the underlying pathophysiology of asthma. As a monitoring tool, EDN has shown good results in children with asthma as well as other allergic diseases. In children too young to fully participate in lung function tests, EDN levels may be useful as an alter native measurement of eosinophilic inflammation. EDN can also be used in adult patients and in multiple specimen types (e.g., serum, sputum, bronchoalveolar lavage fluid, and nasal lavage fluid). These results are repeatable and reproducible. In conclusion, EDN may be a novel biomarker for the diagnosis, treatment, and monitoring of asthma/allergic disease. PMID:23390439

  11. Esophageal dilation in eosinophilic esophagitis.

    PubMed

    Richter, Joel E

    2015-10-01

    Tissue remodeling with scaring is common in adult EoE patients with long standing disease. This is the major factor contributing to their complaints of solid food dysphagia and recurrent food impactions. The best tests to define the degree of remodeling are barium esophagram, high resolution manometry and endoscopy. Many physicians are fearful to dilate EoE patients because of concerns about mucosal tears and perforations. However, multiple recent case series attest to the safety of esophageal dilation and its efficacy with many patients having symptom relief for an average of two years. This chapter will review the sordid history of esophageal dilation in EoE patients and outline how to perform this procedure safely. The key is graduated dilation over one to several sessions to a diameter of 15-18 mm. Postprocedural pain is to be expected and mucosal tears are a sign of successful dilation, not complications. In some healthy adults, occasional dilation may be preferred to regular use of medications or restricted diets. This approach is now supported by recent EoE consensus statements and societal guidelines.

    Background Migraine is a highly disabling condition for the individual and also has wide-reaching implications for society, healthcare services, and the economy. Sumatriptan is an abortive medication for migraine attacks, belonging to the triptan family. Subcutaneous administration may be preferable to oral for individuals experiencing nausea and/or vomiting Objectives To determine the efficacy and tolerability of subcutaneous sumatriptan compared to placebo and other active interventions in the treatment of acute migraine attacks in adults. Search methods We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, online databases, and reference lists for studies through 13 October 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using subcutaneous sumatriptan to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Thirty-five studies (9365 participants) compared subcutaneous sumatriptan with placebo or an active comparator. Most of the data were for the 6 mg dose. Sumatriptan surpassed placebo for all efficacy outcomes. For sumatriptan 6 mg versus placebo the NNTs were 2.9, 2.3, 2.2, and 2.1 for pain-free at one and two hours, and headache relief at one and two hours, respectively, and 6.1 for sustained pain-free at 24 hours. Results for the 4 mg and 8 mg doses were similar to the 6 mg dose, with 6 mg significantly better than 4 mg only for pain-free at one hour, and 8 mg significantly better than 6 mg only for headache relief at one hour. There was no evidence of increased migraine relief if a second dose of sumatriptan 6

    This study was purposed to comparatively analyze the cytogenetic characteristics between 566 cases of adult acute lymphoblastic leukemia (aALL) and 586 cases of childhood acute lymphoblastic leukemia (cALL). The cytogenetic analysis of all the patients was performed, and the FISH detection for partial patients was carried out. The result showed that the difference of chromosome abnormality between cALL and aALL was statistically significant. The percentage of abnormal karyotypes in aALL was 62.0%, including mainly t(9;22)(q34;q11), hypodiploidy, hyperdiploidy (47 - 50), abn(6q), abn(9p) and -7, most of which conferring an unfavorable prognosis. The percentage of abnormal karyotypes in cALL was 39.2%, composed mainly of high hyperdiploidy, hypodiploidy, TEL/AML1(+), +8, hyperdiploidy (47 - 50) and +21, etc, most of which conferring a favorable prognosis. The incidences of abnormal karyotypes, total hypodiploidy, total hyperdiploidy (47 - 50), t(9;22)(q34;q11), -7, abn(7q), abn(14q32) and +Ph in aALL were significantly higher than those of cALL (p < 0.05), whereas the incidences of normal karyotype (N), high hyperdiploidy, +8, +21*2 and TEL/AML1(+) in cALL were significantly higher than those of aALL (p < 0.05). 20.5% of aALL were Ph+ aALL, with 63.8% of which being with additional abnormalities, composed mainly of +Ph, -7, i (9q+), 9p-, +8, +21, +X, 6q-, abn(14q32) and +14. In contrast, only 4.4% of cALL were Ph+ aALL, with 42.3% of which being with additional abnormalities, including mainly abn(9p), abn(7p), -7, 17p- and +21. It is concluded that almost every chromosome is involved in the numerical and structural abnormalities and complex karyotypes are common. The significant difference of chromosome abnormality exists between aALL and cALL.

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting commonly associated with migraine headaches. Objectives To determine the efficacy and tolerability of aspirin, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 10 March 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using aspirin to treat a discrete migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Thirteen studies (4222 participants) compared aspirin 900 mg or 1000 mg, alone or in combination with metoclopramide 10 mg, with placebo or other active comparators, mainly sumatriptan 50 mg or 100 mg. For all efficacy outcomes, all active treatments were superior to placebo, with NNTs of 8.1, 4.9 and 6.6 for 2-hour pain-free, 2-hour headache relief, and 24-hour headache relief with aspirin alone versus placebo, and 8.8, 3.3 and 6.2 with aspirin plus metoclopramide versus placebo. Sumatriptan 50 mg did not differ from aspirin alone for 2-hour pain-free and headache relief, while sumatriptan 100 mg was better than the combination of aspirin plus metoclopramide for 2-hour pain-free, but not headache relief; there were no data for 24-hour headache relief.

    Background Mefenamic acid is a non-steroidal anti-inflammatory drug (NSAID). It is most often used for treating pain of dysmenorrhoea in the short term (seven days or less), as well as mild to moderate pain including headache, dental pain, postoperative and postpartum pain. It is widely available in many countries worldwide. Objectives To assess the efficacy of single dose oral mefenamic acid in acute postoperative pain, and any associated adverse events. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to December 2010. Selection criteria Single oral dose, randomised, double-blind, placebo-controlled trials of mefenamic acid for relief of established moderate to severe postoperative pain in adults. Data collection and analysis Studies were assessed for methodological quality and the data extracted by two review authors independently. Summed total pain relief (TOTPAR) or pain intensity difference (SPID) over 4 to 6 hours was used to calculate the number of participants achieving at least 50% pain relief. These derived results were used to calculate, with 95% confidence intervals, the relative benefit compared to placebo, and the number needed to treat (NNT) for one participant to experience at least 50% pain relief over 4 to 6 hours. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals was collected. Main results Four studies with 842 participants met the inclusion criteria; 126 participants were treated with mefenamic acid 500 mg, 67 with mefenamic acid 250 mg, 197 with placebo, and 452 with lignocaine, aspirin, zomepirac or nimesulide. Participants had pain following third molar extraction, episiotomy and orthopaedic surgery. The NNT for at least 50% pain relief over 6 hours with a single dose of mefenamic acid 500 mg compared to placebo was 4.0 (2

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise. PMID:27450438

    Background and Objective. Despite the extensive reporting of eosinophilic esophagitis (EoE) from industrialized developed countries, reports from developing countries are rare. The aim of our study was to determine the epidemiological, clinical, and endoscopic features of EoE and response to therapy in children and adults from a developing country, Saudi Arabia. Methods. We identified patients diagnosed with EoE in our center from 2004 to 2011. EoE was defined as esophageal mucosal infiltration with a peak eosinophil count ≥15 eosinophils/high-powered field. Results. Forty-five patients were diagnosed with EoE (37 children and 8 adults; 36 males; median age 10.5 years, range from 1-37 years). Feeding difficulty, vomiting/regurgitation, and failure to thrive predominated in young children, whereas dysphagia and food impactions predominated in older children and adults. Allergy testing revealed food sensitization in 12 of 15 patients (80%); 3 responded to elemental formula, while 8 failed to respond to dietary manipulation after the allergy testing. Thirty-nine patients achieved remission by swallowed inhaled fluticasone. The majority of patients experienced a recurrence of symptoms upon the discontinuation of fluticasone. Conclusion. Our data indicate that EoE is increasingly recognized in Saudi Arabia and show many similarities to data from North America and Europe.

    Studies have shown that eosinophils are closely related to pathogenesis of bronchial asthma. Eosinophils release eosinophil cationic protein (ECP), which plays an important role in infection and allergic reactions. Serum ECP mRNA expression in children with bronchial asthma has not been adequately investigated. We analyzed serum ECP mRNA expression in 63 children with bronchial asthma and 21 healthy children by using reverse-transcriptase polymerase chain reaction to understand the role of ECP in children with bronchial asthma. The children with bronchial asthma were segregated into acute-phase and stable-phase groups, based on the severity of the illness. Serum ECP mRNA expression in children with bronchial asthma (0.375 ± 0.04) was significantly higher than that in healthy controls (0.20 ± 0.02; P < 0.05). Additionally, children in the acute-phase group showed higher ECP mRNA expression level (0.44 ± 0.06) than those in the stable-phase (0.31 ± 0.03) and healthy control groups (0.20 ± 0.02; P < 0.05), while the level in the stable-phase (0.31 ± 0.03) was markedly higher than that in the healthy control group (0.20 ± 0.02; P < 0.05). Detection of serum ECP mRNA expression level has possible applications in the diagnosis and treatment of children with bronchial asthma.

    We examined the acute effect of physical exercise on prefrontal cortex activity in older adults using functional near-infrared spectroscopy (NIRS). Fourteen older adults visited our laboratory twice: once for exercise and once for the control condition. On each visit, subjects performed working memory tasks before and after moderate intensity exercise with a cycling ergo-meter. We measured the NIRS response at the prefrontal cortex during the working memory task. We found that physical exercise improved behavioral performance of the working memory task compared with the control condition. Moreover, NIRS analysis showed that physical exercise enhanced the prefrontal cortex activity, especially in the left hemisphere, during the working memory task. These findings suggest that the moderate intensity exercise enhanced the prefrontal cortex activity associated with working memory performance in older adults.

    Despite major advances in our understanding of TGF-β signaling in multiple cell types, little is known about the direct target genes of this pathway in human eosinophils. These cells constitute the major inflammatory component present in the sputum and lung of active asthmatics and their numbers correlate well with disease severity. During the transition from acute to chronic asthma, TGF-β levels rise several fold in the lung which drives fibroblasts to produce extracellular matrix (ECM) and participate in airway and parenchymal remodeling. In this report, we use purified blood eosinophils from healthy donors and analyze baseline and TGF-β responsive genes by RNA Seq, and demonstrate that eosinophils (PBE) express 7981 protein-coding genes of which 178 genes are up-regulated and 199 genes are down-regulated by TGF-β. While 18 target genes have been previously associated with asthma and eosinophilic disorders, the vast majority have been implicated in cell death and survival, differentiation, and cellular function. Ingenuity pathway analysis revealed that 126 canonical pathways are activated by TGF-β including iNOS, TREM1, p53, IL-8 and IL-10 signaling. As TGF-β is an important cytokine for eosinophil function and survival, and pulmonary inflammation and fibrosis, our results represent a significant step toward the identification of novel TGF-β responsive genes and provide a potential therapeutic opportunity by selectively targeting relevant genes and pathways.

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Five studies (1356 participants) compared oral diclofenac with placebo, and one also compared it with sumatriptan; none combined diclofenac with a self administered antiemetic. Four studies treated attacks with single doses of medication, and two allowed an optional second dose for inadequate response. Only two studies, with three active treatment arms, provided data for pooled analysis of primary outcomes. For single doses of diclofenac

    Background Acute lymphoblastic leukemia (ALL) is aggressive cancer, especially in adults as only 20-40% is cured with current treatment regimens. Objectives The aim of this study is to evaluate prognostic factors and their effects on survival in ALL patients in the Northeast of Iran. Methods In a descriptive and retrospective study from 2009 to 2015, 48 ALL patients referred to hematology-oncology clinic. Age, sex, fever, blood group, type of ALL and consumption of amphotericin B, forms of cytogenetic, survival in the patients, WBC, hemoglobin, and platelet were checked in the first referral for every patient. The mean follow-up was 27.3 months in which 28 patients (59.3%) died. overall survival (OS) was plotted by GraphPad Prism 5 and the Log-rank test was used for analysis of survival with risk factors. Results The mean age for all the ALL patients at diagnosis was 32.3 years (range, 15-71 years), and 81.3% were male. Of all patients, 62.5% had fever and 25% consumed amphotericin B. 1-, 2-, 3-, 4-, 5-year OS rates were 62.2%, 52.7%, 40.6%, 39.1%, 22.2%, respectively. 75%, 29.2% and 39.6% of patients had WBC < 20 × 103/μl, Hb < 7 g/dL and platelet < 30 × 103/μL, respectively. There was a significant difference in survival based on age (P = 0.000). Conclusions Based on the results, age > 35 years is the most prognostic factor in ALL patients. Also, patients who received amphotericin B had lower life expectancy because these patients were suffering from fungal infection or due to lack of response to antibacterial drugs, they have been treated with amphotericin B.

    Aberrant activation of the Wnt pathway plays a pathogenetic role in tumors and has been associated with adverse outcome in acute lymphoblastic leukemia (ALL). Lymphoid enhancer binding factor 1 (LEF1), a key mediator of Wnt signaling, has been linked to leukemic transformation, and LEF1 mutations have been identified in T-ALL. Here we found LEF1 is highly expressed in 25.0% adult ALL patients and LEF1 high expression was associated with high-risk leukemia factors (high WBC, Philadelphia chromosome positive, complex karyotype), shorter event-free survival (EFS), and high relapse rates in patients with B-ALL. LEF1 high expression is also associated with high mutation rate of Notch1 and JAK1 in T-ALL. We identified 2 novel LEF1 mutations (K86E and P106L) in 4 of 131 patients with ALL, and those patients with high-risk ALL (high WBC, complex karyotype). These results suggest a role for LEF1 mutations in leukemogenesis. We further explored the effect of the mutations on cell proliferation and found both mutations significantly promoted the proliferation of ALL cells. We also observed the effect of LEF1 and its mutations on the transcription of its targets, c-MYC and Cyclin D1. We found LEF1 increased the promoter activity of its targets c-MYC and Cyclin D1, and LEF1 K86E and P106L mutants further significantly enhanced this effect. We also observed that the c-MYC and Cyclin D1 mRNA levels were significantly increased in patients with LEF1 high expression compared with those with low expression. Taken together, our findings indicate high LEF1 expression and mutation are associated with high-risk leukemia and our results also revealed that LEF1 high expression and/or gain-of-function mutations are involved in leukemogenesis of ALL.

    Background: Poor cerebral perfusion may contribute to cognitive impairment in type 2 diabetes mellitus (T2DM). We conducted a randomized controlled trial to test the hypothesis that resveratrol can enhance cerebral vasodilator function and thereby alleviate the cognitive deficits in T2DM. We have already reported that acute resveratrol consumption improved cerebrovascular responsiveness (CVR) to hypercapnia. We now report the effects of resveratrol on neurovascular coupling capacity (CVR to cognitive stimuli), cognitive performance and correlations with plasma resveratrol concentrations. Methods: Thirty-six T2DM adults aged 40–80 years were randomized to consume single doses of resveratrol (0, 75, 150 and 300 mg) at weekly intervals. Transcranial Doppler ultrasound was used to monitor changes in blood flow velocity (BFV) during a cognitive test battery. The battery consisted of dual-tasking (finger tapping with both Trail Making task and Serial Subtraction 3 task) and a computerized multi-tasking test that required attending to four tasks simultaneously. CVR to cognitive tasks was calculated as the per cent increase in BFV from pre-test basal to peak mean blood flow velocity and also as the area under the curve for BFV. Results: Compared to placebo, 75 mg resveratrol significantly improved neurovascular coupling capacity, which correlated with plasma total resveratrol levels. Enhanced performance on the multi-tasking test battery was also evident following 75 mg and 300 mg of resveratrol. Conclusion: a single 75 mg dose of resveratrol was able to improve neurovascular coupling and cognitive performance in T2DM. Evaluation of benefits of chronic resveratrol supplementation is now warranted. PMID:27420093

    The present investigation was designed to analyse the effects of acute lethal graft-versus-host disease (GVHD) in adult (DA x LEW)F1 rats on cellular proliferation within the liver. The influence of the host thymus on GVHD-induced proliferation was also assessed. From 1-28 days after initiation of GVHD [3H]thymidine ([3H]-TdR) was injected i.v. and rats were killed one hour later. Percentage labelled cells (LI) of periportal infiltrating cells (PIC), hepatocytes (H), and sinusoidal lining cells (SC) were counted. Mean values for control rats were 0.3 +/- 0.1% (H), 0.4 +/- 0.1% (SC) and 0.2 +/- 0.1% (PIC). GVHD rats demonstrated a significant increase in LI of PIC (days 1-21), SC (days 2-17) and H (days 2-17). Most labelled cells in PIC were large lymphocytes. Peak LI values were 7.0 +/- 1.0% PIC (day 17), 6.8 +/- 0.9% SC (day 17), and 5.2 +/- 0.9% H (day 7), with all cellular compartments returning to near normal LI values by day 28. Stimulation of cellular proliferation occurred in all three liver cell compartments in neonatally thymectomized (TXM) rats. The intensity of GVHD-induced cell proliferation was significantly decreased at day 7 in all compartments and PIC was dramatically decreased at day 21 in TXM-GVHD rats as compared to non-TXM-GVHD rats. It is hypothesized that the general stimulation of hepatocyte cell proliferation in GVHD is related to the secretion of lymphokines by primarily donor and secondarily host T cells in the periportal infiltrate.

    Chewing reportedly contributes to satiation and satiety signals. Attempts to document and quantify this have led to small and inconsistent effects. The present trial manipulated oral processing effort though required chewing of gums of different hardness and measured appetitive sensations, energy intake, gastric emptying, GI transit time, and concentrations of glucose, insulin, GLP-1, ghrelin and pancreatic polypeptide. Sixty adults classified by sex and BMI (15 each of lean females, obese females, lean males and obese males) were tested in a randomized, controlled, cross-over trial with three arms. They chewed nothing, soft gum or hard gum for 15 min while sipping grape juice (10% of individual energy needs) containing acetaminophen and lactulose on one day each separated by 7 days. Electromyographic recordings and self-reports were obtained during and after chewing to quantify oral processing effort. Blood was sampled through an indwelling catheter and appetite ratings were obtained at baseline and at 0, 15, 30, 45, 60, 90, 120, 180 and 240 min after chewing initiation. Breath samples were collected at 10 min intervals for the first 2h and at 30 min intervals for the next 2h. No effects of chewing were observed for appetitive sensations or gut peptide concentrations. Energy intake tended to decline in lean and increase in obese participants so that daily energy intake differed significantly between the two groups when chewing either gum, while no difference was observed on the non-chewing day. Serum glucose and insulin were significantly lower at selected time points 90-240 min after chewing compared to baseline and the non-chewing day. These data indicate chewing effort does not affect appetitive sensations or gut peptide secretion, but may exert a small differential effect on acute energy intake in lean and obese individuals and lead to greater post-prandial declines of serum glucose and insulin.

    Objective HIV-infected patients in Africa are vulnerable to severe recurrent infection with Streptococcus pneumoniae, but no effective preventive strategy has been developed. We set out to determine which factors influence in-hospital mortality and long-term survival of Malawians with invasive pneumococcal disease. Design, setting and patients Acute clinical features, inpatient mortality and long-term survival were described among consecutively admitted hospital patients with S. pneumoniae in the blood or cerebrospinal fluid. Factors associated with inpatient mortality were determined, and patients surviving to discharge were followed to determine their long-term outcome. Results A total of 217 patients with pneumococcal disease were studied over an 18-month period. Among these, 158 out of 167 consenting to testing (95%) were HIV positive. Inpatient mortality was 65% for pneumococcal meningitis (n = 64), 20% for pneumococcaemic pneumonia (n = 92), 26% for patients with pneumococcaemia without localizing signs (n = 43), and 76% in patients with probable meningitis (n = 17). Lowered consciousness level, hypotension, and age exceeding 55 years at presentation were associated with inpatient death, but not long-term outcome in survivors. Hospital survivors were followed for a median of 414 days; 39% died in the community during the study period. Outpatient death was associated with multilobar chest signs, oral candidiasis, and severe anaemia as an inpatient. Conclusion Most patients with pneumococcal disease in Malawi have HIV co-infection. They have severe disease with a high mortality rate. At discharge, all HIV-infected adults have a poor prognosis but patients with multilobar chest signs or anaemia are at particular risk.

    Acute fulminant myocarditis (AFM) is a serious heart disease with limited treatment. This observational retrospective study aimed to investigate whether intravenous immunoglobulin (IVIG) was able to improve left ventricular function and reduce the episodes of arrhythmia in adult patients with AFM. The medical records of all patients with AFM who were admitted to the Critical Care Unit of Guangdong General Hospital (Guangzhou, China) between January 2001 and December 2010 were reviewed. A cohort of 58 patients was included in the study. Of these 58, 32 patients were treated with IVIG (400 mg/kg per day) for five days, while the remaining patients did not receive IVIG therapy. The patients who received IVIG therapy had a higher left ventricular ejection fraction (LVEF) and a reduced left ventricular end-diastolic diameter (LVDD) compared with the non-IVIG therapy patients four weeks subsequent to the treatment (PLVEF=0.011 and PLVDD=0.048). The post-treatment incidence of ventricular tachycardia/ventricular fibrillation (VT/VF) and atrioventricular block (AVB) was reduced in the patients who received IVIG therapy compared with the baseline values (PVT/VF=0.025, PAVB=0.003); however, no significant differences were observed in the non-IVIG therapy patients (PVT/VF=0.564, PAVB=0.083) following treatment. There were two mortalities in the IVIG therapy group and seven in the non-IVIG therapy group (P=0.072). This retrospective study suggested that the use of IVIG for the treatment of AFM may be associated with improved left ventricular function and reduced episodes of fulminant arrhythmias.

    The aim of our study was to investigate the etiological and demographical characteristics of acute adult poisoning cases admitted to a university hospital in Tabriz, Iran. This retrospective study was performed on 1342 poisoning admissions to a university hospital from 2003 to 2005, by data collection from the medical records of patients. Poisonings were 5.40% of the total admissions. There was a predominance of female patients (55.7%) compared to male patients (44.3%) with a female-to-male ratio of 1.2:1. Most poisonings occurred in the age range of 11-20 years (38.9%). Drugs were the most common cause of poisonings (60.8%). Among the drug poisonings, benzodiazepines (40.31%) were the most frequent agents, followed by antidepressants (31.98%). The seasonal distribution in poisoning patients suggested a peak in spring (28%) and summer (27.5%). In 9.8% of cases accidental and in 90.2% intentional poisonings were evident. Most suicide attempts were made by women (58.51%) and unmarried people (51.4%).The mean duration of hospitalization was 3.02 +/- 2.8 days. There were 28 (2.3%) deaths; the majority (13 cases) was due to pesticides. This was a university hospital-based study, so these results may not be representative of the general population. Despite this drawback, these data still provide important information on the characteristics of the poisoning in this part of Iran. To prevent such poisonings, the community education about the danger of central nervous system-acting drugs and reducing the exposure period of people to pesticides are recommended. PMID:19734268

    A 55-year-old woman presented with a 3-year history of recurrent episodes of pruritic cellulitis-like erythematous plaques, mostly located on the limbs. Simultaneously, fever, malaise and peripheral eosinophilia were noted. The clinical diagnosis of eosinophilic cellulitis (also known as Well's syndrome) was supported by the histopathological finding of typical "flame figures". Treatment with dapsone was initiated at a dose of 50 mg per day. After one year of follow-up the patient was relapse-free. Eosinophilic cellulitis is an uncommon, recurrent inflammatory skin disease. The management is often a challenge, due to the frequent need for long-term therapy. Dapsone is an effective and safe treatment option. PMID:27617724

    Eosinophilic esophagitis (EoE) is an allergic disorder characterized by infiltration of the oesophagus with eosinophils. We had previously reported association of the TSLP/WDR36 locus with EoE. Here we report genome-wide significant associations at four additional loci; c11orf30 and STAT6, which have been previously associated with both atopic and autoimmune diseases, and two EoE-specific loci, ANKRD27 that regulates the trafficking of melanogenic enzymes to epidermal melanocytes and CAPN14, that encodes a calpain whose expression is highly enriched in the oesophagus. The identification of five EoE loci, not only expands our aetiological understanding of the disease but may also represent new therapeutic targets to treat the most debilitating aspect of EoE, oesophageal inflammation and remodelling.

    Eosinophilic prostatitis is a rare form of abacterial prostatitis with uncertain aetiology. Its clinical presentation, like other types of abacterial prostatitis, commonly mimics carcinoma of the prostate. Transrectal ultrasound may be helpful in the diagnosis of prostatitis but histological confirmation is necessary. Prostatic specific antigen has been widely used in the diagnosis and follow-up of patients with prostatic carcinoma. High levels of this antigen (greater than 30 micrograms/l) have been claimed to be highly specific for prostate cancer, although lesser elevations may also occur in patients with large benign prostate glands and in bacterial prostatitis. We report 3 patients with histologically proven eosinophilic prostatitis and high levels of prostatic specific antigen. This diagnosis may closely mimic carcinoma of the prostate and must be excluded by histological examination of biopsy material before treatment for presumed prostate carcinoma is initiated.

    The immaturity of the CNS at birth greatly affects injury after stroke but the contribution of the blood-brain barrier (BBB) to the differential response to stroke in adults and neonates is poorly understood. We asked whether the structure and function of the BBB is disrupted differently in neonatal and adult rats by transient middle cerebral artery occlusion. In adult rats, albumin leakage into injured regions was markedly increased during 2-24 h reperfusion but leakage remained low in the neonates. Functional assays employing intravascular tracers in the neonates showed that BBB permeability to both large (70 kDa dextran) and small (3 kDa dextran), gadolinium (III)-diethyltriaminepentaacetic acid tracers remained largely undisturbed 24 h after reperfusion. The profoundly different functional integrity of the BBB was associated with the largely nonoverlapping patterns of regulated genes in endothelial cells purified from injured and uninjured adult and neonatal brain at 24 h (endothelial transcriptome, 31,042 total probe sets). Within significantly regulated 1266 probe sets in injured adults and 361 probe sets in neonates, changes in the gene expression of the basal lamina components, adhesion molecules, the tight junction protein occludin, and matrix metalloproteinase-9 were among the key differences. The protein expression of collagen-IV, laminin, claudin-5, occludin, and zonula occludens protein 1 was also better preserved in neonatal rats. Neutrophil infiltration remained low in acutely injured neonates but neutralization of cytokine-induced neutrophil chemoattractant-1 in the systemic circulation enhanced neutrophil infiltration, BBB permeability, and injury. The markedly more integrant BBB in neonatal brain than in adult brain after acute stroke may have major implications for the treatment of neonatal stroke. PMID:22787045

    Racecadotril is a guideline-recommended treatment to alleviate symptoms of acute diarrhea. A systematic review of randomized studies was performed comparing efficacy and safety of treatment with racecadotril to that with placebo or active treatments in adults. In five double-blind studies, racecadotril and placebo had comparable tolerability, but racecadotril was more effective. This was consistent across multiple efficacy parameters including duration of diarrhea, number of diarrheic stools, abdominal pain, and meteorism; it was also consistent across countries in Africa, Asia, and Europe. In six randomized studies in outpatients comparing racecadotril to loperamide, resolution of symptoms occurred with similar speed and efficacy; however, racecadotril treatment was associated with less rebound constipation and less abdominal discomfort. The seventh comparative study performed in geriatric nursing home residents reported a superior efficacy of racecadotril. In direct comparison with Saccharomyces boulardii treatment, racecadotril exhibited similar tolerability but was more efficacious. One study compared racecadotril to octreotide in patients with acute diarrhea requiring hospitalization, rehydration, and antibiotic treatment; in this cohort, octreotide was more efficacious than racecadotril. In conclusion, in adults with acute diarrhea, racecadotril is more efficacious than placebo or S. boulardii, similarly efficacious as loperamide and, in patients with moderate to severe disease as add-on to antibiotics, less than octreotide. The tolerability of racecadotril is similar to that of placebo or S. boulardii and better than that of loperamide, particularly with regard to risk of rebound constipation. Taken together, these data demonstrate that racecadotril is a suitable treatment to alleviate symptoms of acute diarrhea in adults. PMID:27790616

    Canine eosinophilic granuloma (CEG) is a rare skin disease of unknown origin. It has been reported in Siberian huskies, Cavalier King Charles spaniels and occasionally in other breeds. The lesions comprise nodules or plaques, mostly localised in the oral cavity. A case of a single cutaneous nodular lesion of CEG on the eyelid of a Siberian husky is described. Complete remission was achieved with oral glucocorticoid treatment.

    Of six cats with eosinophilic enteritis, two had lesions confined to the intestinal tract, and four had varied disseminated eosinophilic infiltration of other organs. The lesions in these cats are similar to those of the hypereosinophilic syndrome in man. A feline hypereosinophilic syndrome is proposed, consisting of eosinophilic enteritis, disseminated eosinophilic disease, and eosinophilic leukemia. PMID:7467078

    Acute gastroenteritis caused by human noroviruses (NoVs) has become an important public health problem worldwide. This study was carried out to investigate the rates of NoV infections and the genetic characteristics of NoVs in adult outpatients with acute gastroenteritis in Ji'nan, a large eastern city in China. A total of 480 fecal samples were collected from outpatients at the Shandong University Qilu Hospital between June 2010 and May 2011. Of the collected samples, 42 (42/480, 8.75 %) were positive for NoVs by RT-PCR, and seven different genotypes were identified: GI-1, GI-4, GII-1, GII-3, GII-4, GII-6 and GII-13, of which GII-4 was the most prevalent (29/42, 69.0 %). Phylogenetic and Simplot analyses showed that three recombinant strains were detected: two GII-4 polymerase/GII-3 capsid recombinants and one GII-6 polymerase/GII-4 capsid recombinant. This study indicated that NoV was a common causative agent of sporadic acute gastroenteritis in adults in Ji'nan, China, and that NoV GII-4 was the predominant strain during this period. Three recombinant strains were identified in which GII-6 polymerase/GII-4 capsid was detected for the first time in China.

    Symmetric skin thickening of the limbs with deep fascial inflammation is the hallmark of eosinophilic fasciitis. We describe a woman who presented with unilateral progressive skin thickening. Examination of a full-thickness skin biopsy revealed an inflammatory process and fascial changes consistent with eosinophilic fasciitis. In contrast to other scleroderma mimics, eosinophilic fasciitis generally responds rapidly to glucocorticoid therapy. It is possible that unilateral eosinophilic fasciitis is under-recognized and can easily be misdiagnosed as another scleroderma variant if a full-thickness biopsy is not reviewed by a dermatopathologist. Recognition of this subtype of eosinophilic fasciitis is important given the profound differences in prognosis of eosinophilic fasciitis and other scleroderma variants.

    Th2–eosinophil immune responses are well known for mediating host defence against helminths. Herein we describe a function of Th2–eosinophil responses in counteracting the development of arthritis. In two independent models of arthritis, Nippostrongylus brasiliensis infection leads to Th2 and eosinophil accumulation in the joints associated with robust inhibition of arthritis and protection from bone loss. Mechanistically, this protective effect is dependent on IL-4/IL-13-induced STAT6 pathway. Furthermore, we show that eosinophils play a central role in the modulation of arthritis probably through the increase of anti-inflammatory macrophages into arthritic joints. The presence of these pathways in human disease is confirmed by detection of GATA3-positive cells and eosinophils in the joints of rheumatoid arthritis patients. Taken together, these results demonstrate that eosinophils and helminth-induced activation of the Th2 pathway axis effectively mitigate the course of inflammatory arthritis. PMID:27273006

    Abstract Objective To analyze and compare the health-related quality of life of adult survivors of acute lymphocytic leukemia and Wilms’ tumor amongst themselves and in relation to healthy participants. Methods Ninety participants aged above 18 years were selected and divided into three groups, each comprising 30 individuals. The Control Group was composed of physically healthy subjects, with no cancer history; and there were two experimental groups: those diagnosed as acute lymphocytic leukemia, and those as Wilms’ Tumor. Quality of life was assessed over the telephone, using the Medical Outcomes Study 36-Item Short Form Health Survey. Results Male survivors presented with better results as compared to female survivors and controls in the Vitality domain, for acute lymphocytic leukemia (p=0.042) and Wilms’ tumor (p=0.013). For acute lymphocytic leukemia survivors, in Social aspects (p=0.031), Mental health (p=0.041), and Emotional aspects (p=0.040), the latter also for survivors of Wilms’ tumor (p=0.040). The best results related to the Functional capacity domain were recorded for the experimental group that had a late diagnosis of acute lymphocytic leukemia. There were significant differences between groups except for the Social and Emotional domains for self-perceived health, with positive responses that characterized their health as good, very good, and excellent. Conclusion Survivors of acute lymphocytic leukemia showed no evidence of relevant impairment of health-related quality of life. The Medical Outcomes Study 36-Item Short Form Health Survey (via telephone) can be a resource to access and evaluate survivors. PMID:26537509

    Recovery-oriented care acknowledges the unique journey that consumers lead with the aim of regaining control of their lives in order to live a good life. Recovery has become a dominant policy-directed model of many mental health care organizations, but in older-adult acute mental health inpatient settings, nurses do not have a clear description of how to be recovery-oriented. The aims of this study were to determine the extent to which elements of existing nursing practice resemble the domains of recovery-oriented care and provide a baseline understanding of practice in preparation for transformation to recovery-oriented mental health care provision. An exploratory, qualitative research design was used to meet the research aims. A purposive sample of mental health nurses (N = 12) participated in focus groups in three older-adult inpatient settings in Australia. A general inductive approach was used to analyze the qualitative data. The mental health nurses in this study readily discussed aspects of their current practice within the recovery domains. They described pragmatic ways to promote a culture of hope, collaborative partnerships, meaningful engagement, autonomy and self-determination, and community participation and citizenship. Nurses also discussed challenges and barriers to recovery-oriented care in older-adult acute mental health settings. This study identified a reasonable baseline understanding of practice in preparation for transformation to recovery-oriented older-adult mental healthcare provision. A concerted drive focused on recovery education is required to effectively embed a recovery-orientated paradigm into older-adult mental health settings.

    The decongestive effect of Rhinopront syrup was assessed in 18 adults and 18 children with acute rhinitis, by comparison to a matching placebo syrup and to a commercial standard decongestant (Triaminic tablets or drops). The evolution of symptoms following single dose administration of each treatment was estimated both by objective measurements of nasal resistance using bilateral rhinomanometry and by subjective evaluation of nasal congestion and aspect of the mucosa. In children, the treatment was continued over the next 4 days and the global clinical efficacy of the formulations was subjectively evaluated by the parents. In adult patients, a significant decrease in nasal resistance was obtained after a single dose of Rhinopront (15 g). The effect was already important after 0.5 h and reached a minimum of approximately 50% of baseline within 1 to 2 h; the drop in nasal resistance was significantly less intense for Triaminic (p < 0.05; 0.5-1-h period) and for the placebo (p < 0.05; 0.5-2-h period). In children, the scatter of rhinomanometric measurements precluded the observation of any significant within- or between-group differences; however, a significantly lower nasal congestion score was observed for Rhinopront than placebo, between 4 and 10 h after single dose administration (1 g per year of age). The present work suggests that Rhinopront is an effective nasal decongestant in adults and children with acute congestive rhinitis and supports the adequacy of the proposed twice-daily dosing rate.

    The authors report a case of a black African patient who suffers from a chronic eosinophilic pneumonia. In view of the lack of precise reporting in the literature of such a case in black Africans, the initial difficulty of strictly excluding a parasitologic etiology is discussed. From the comparison of paraclinical and clinical data with those of the literature, the authors emphasize the close relationship between asthma and chronic eosinophilic pneumonia and the role of alveolar eosinophils in the physiopathology of that illness.

    Eosinophils and their products are probably important in the pathophysiology of allergic diseases, such as bronchial asthma, and in host immunity to certain organisms. An association between environmental fungal exposure and asthma has been long recognized clinically. Although products of microorganisms (e.g., lipopolysaccharides) directly activate certain inflammatory cells (e.g., macrophages), the mechanism(s) that triggers eosinophil degranulation is unknown. In this study we investigated whether human eosinophils have an innate immune response to certain fungal organisms. We incubated human eosinophils with extracts from seven environmental airborne fungi (Alternaria alternata, Aspergillus versicolor, Bipolaris sorokiniana, Candida albicans, Cladosporium herbarum, Curvularia spicifera, and Penicillium notatum). Alternaria and Penicillium induced calcium-dependent exocytosis (e.g., eosinophil-derived neurotoxin release) in eosinophils from normal individuals. Alternaria also strongly induced other activation events in eosinophils, including increases in intracellular calcium concentration, cell surface expression of CD63 and CD11b, and production of IL-8. Other fungi did not induce eosinophil degranulation, and Alternaria did not induce neutrophil activation, suggesting specificity for fungal species and cell type. The Alternaria-induced eosinophil degranulation was pertussis toxin sensitive and desensitized by preincubating cells with G protein-coupled receptor agonists, platelet-activating factor, or FMLP. The eosinophil-stimulating activity in Alternaria extract was highly heat labile and had an M(r) of approximately 60 kDa. Thus, eosinophils, but not neutrophils, possess G protein-dependent cellular activation machinery that directly responds to an Alternaria protein product(s). This innate response by eosinophils to certain environmental fungi may be important in host defense and in the exacerbation of inflammation in asthma and allergic diseases.

    Abstract The aim of this study was to investigate the role of microRNA-335 (miR-335) in determining the treatment response and prognosis in adult acute myeloid leukemia (AML) patients receiving the cytarabine (Ara-C)-based chemotherapy. A total of 204 adult AML patients were collected. The miR-335 levels in serum and bone marrow samples from these patients were determined. All patients received Ara-C-based standard induction chemotherapy regimens. The treatment response to Ara-C-based chemotherapy was evaluated. All patients were followed for prognostic analyses. The levels of miR-335 in bone marrow and serum samples from adult AML patients achieving complete response were significantly higher than those without. The serum miR-335 level was not associated with the chemotherapy response and prognosis in these AML patients. In contrast, high bone marrow miR-335 level was significantly associated with a poor treatment response and also predicted a worse prognosis indicated by the relapse-free survival and overall survival periods in adult AML patients receiving Ara-C-based chemotherapy. Our finding suggests that bone marrow miR-335 level may be used as a marker to predict the chemotherapy response and prognosis in adult AML patients. PMID:26287405

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers do not seek professional help, relying instead on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce symptoms commonly associated with migraine headaches. Objectives To determine efficacy and tolerability of ibuprofen, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 22 April 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using self-administered ibuprofen to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and number needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Nine studies (4373 participants, 5223 attacks) compared ibuprofen with placebo or other active comparators; none combined ibuprofen with a self-administered antiemetic. All studies treated attacks with single doses of medication. For ibuprofen 400 mg versus placebo, NNTs for 2-hour pain-free (26% versus 12% with placebo), 2-hour headache relief (57% versus 25%) and 24-hour sustained headache relief (45% versus 19%) were 7.2, 3.2 and 4.0, respectively. For ibuprofen 200 mg versus placebo, NNTs for 2-hour pain-free (20% versus 10%) and 2-hour headache relief (52% versus 37%) were 9.7 and 6.3, respectively. The higher dose was significantly better for 2-hour headache relief than the lower dose. Soluble formulations of ibuprofen 400 mg were better than standard tablets for 1-hour, but not 2-hour headache relief

Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter analgesics. Co-therapy with an antiemetic should help to reduce nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of paracetamol (acetaminophen), alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine in adults. Search methods We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies through 4 October 2010. Selection criteria We included randomised, double-blind, placebo- or active-controlled studies using self-administered paracetamol to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. Numbers of participants achieving each outcome were used to calculate relative risk and numbers needed to treat (NNT) or harm (NNH) compared to placebo or other active treatment. Main results Ten studies (2769 participants, 4062 attacks) compared paracetamol 1000 mg, alone or in combination with an antiemetic, with placebo or other active comparators, mainly sumatriptan 100 mg. For all efficacy outcomes paracetamol was superior to placebo, with NNTs of 12, 5.2 and 5.0 for 2-hour pain-free and 1- and 2-hour headache relief, respectively, when medication was taken for moderate to severe pain. Nausea, photophobia and phonophobia were reduced more with paracetamol than with placebo at 2 hours (NNTs of 7 to 11); more individuals were free of any functional disability at 2 hours with paracetamol (NNT 10); and fewer participants needed rescue medication over 6 hours (NNT 6). Paracetamol 1000 mg plus metoclopramide 10 mg was not significantly different from oral sumatriptan

    Eosinophils, a constitutive component of the columnar-lined gastrointestinal tract, play an essential role in allergic responses and parasitic infections. The tissue density of these cells also increases in a variety of conditions of uncertain etiology. With the exception of the esophageal squamous epithelium, in which no eosinophils are normally present, the population of normal eosinophils in the remainder of the luminal gut is poorly defined. Therefore, histopathologists must rely on their subjective judgment to determine when a diagnosis of eosinophilic gastritis, enteritis, or colitis should be rendered. Eosinophilic esophagitis is currently the best defined and most studied eosinophilic condition of the digestive tract; therefore, the confidence in accurate diagnosis is increasing. In contrast, the characteristic clinicopathologic features of eosinophilic conditions affecting other parts of the digestive tract remain somewhat elusive. This review was designed to present pathologists with simple and practical information for the biopsy-based histopathologic diagnosis of eosinophilic esophagitis, gastritis, enteritis, and colitis. It was prepared by critically reviewing more than 200 articles on the topic, along with incorporating evidence accumulated through our own collective experience. We anticipate that by increasing pathologists' confidence in reporting these abnormal but often nameless eosinophilic infiltrates, we can help better define and characterize their significance.

    Eosinophils promote tissue injury and contribute to the pathogenesis of allergen-triggered diseases like asthma, but the chemical basis of damage to eosinophil targets is unknown. We now demonstrate that eosinophil activation in vivo results in oxidative damage of proteins through bromination of tyrosine residues, a heretofore unrecognized pathway for covalent modification of biologic targets in human tissues. Mass spectrometric studies demonstrated that 3-bromotyrosine serves as a specific “molecular fingerprint” for proteins modified through the eosinophil peroxidase-H2O2 system in the presence of plasma levels of halides. We applied a localized allergen challenge to model the effects of eosinophils and brominating oxidants in human lung injury. Endobronchial biopsy specimens from allergen-challenged lung segments of asthmatic, but not healthy control, subjects demonstrated significant enrichments in eosinophils and eosinophil peroxidase. Baseline levels of 3-bromotyrosine in bronchoalveolar lavage (BAL) proteins from mildly allergic asthmatic individuals were modestly but not statistically significantly elevated over those in control subjects. After exposure to segmental allergen challenge, lung segments of asthmatics, but not healthy control subjects, exhibited a >10-fold increase in BAL 3-bromotyrosine content, but only two- to threefold increases in 3-chlorotyrosine, a specific oxidation product formed by neutrophil- and monocyte-derived myeloperoxidase. These results identify reactive brominating species produced by eosinophils as a distinct class of oxidants formed in vivo. They also reveal eosinophil peroxidase as a potential therapeutic target for allergen-triggered inflammatory tissue injury in humans. PMID:10811853

    In a double-blind, controlled randomized trial, 88 adult patients with acute diarrhea (more than three watery stools per day) received either 400 mg of nifuroxazide twice daily or placebo for 5 days. The mean duration of diarrhea in the nifuroxazide group was 2.09 days versus 3.26 days in the placebo group (p less than 0.004). The number of bowel movements per day diminished and mucus disappeared more quickly in patients treated by nifuroxazide than in patients of the placebo group. Nifuroxazide was well tolerated and no side effects were observed. Nifuroxazide is an effective therapy for acute diarrhea and can be prescribed from the onset of diarrhea without waiting for stool culture results which can be late or negative. PMID:2666238

    The increasing life expectancy in older adults and the better survival of patients with multiple pathologies require the capability to treat complex clinical conditions with an increased risk of iatrogenic complications. Nevertheless, recent improvements in the pharmacological and interventional treatment of acute coronary syndrome (ACS) have promoted a shift from therapeutic nihilism to a more active management of complex ACS cases. Despite the paucity of specific randomized clinical trials, observational studies seem to show benefit of an early invasive treatment in these patients. This approach requires close cooperation of clinical intensivists, interventional cardiologists and cardiovascular surgeons either in a specialized heart center or in a network of hospitals.

    Studies of AMCase inhibition in mouse models of lung eosinophilic inflammation have produced conflicting results with some studies demonstrating inhibition of eosinophilic inflammation and others not. No studies have investigated the role of AMCase inhibition in eosinophilic esophagitis (EoE). We have used a mouse model of egg (OVA) induced EoE to determine whether pharmacologic inhibition of AMCase with allosamidin reduced eosinophilic inflammation and remodeling in the esophagus in EoE. Administration of intra-esophageal OVA for 6 weeks to BALB/c mice induced increased levels of esophageal eosinophils, mast cells, and features of esophageal remodeling (fibrosis, basal zone hyperplasia, deposition of the extracellular matrix protein fibronectin). Administration of intraperitoneal (ip) allosamidin to BALB/c mice significantly inhibited AMCase enzymatic activity in the esophagus. Pharmacologic inhibition of AMCase with ip allosamidin inhibited both OVA induced increases in esophageal eosinophilic inflammation and OVA induced esophageal remodeling (fibrosis, epithelial basal zone hyperplasia, extracellular matrix deposition of fibronectin). This inhibition of eosinophilic inflammation in the esophagus by ip allosamidin was associated with reduced eotaxin-1 expression in the esophagus. Oral allosamidin inhibited eosinophilic inflammation in the epithelium but did not inhibit esophageal remodeling. These studies suggest that pharmacologic inhibition of AMCase results in inhibition of eosinophilic inflammation and remodeling in the esophagus in a mouse model of egg induced EoE partially through effects in the esophagus on reducing chemokines (i.e. eotaxin-1) implicated in the pathogenesis of EoE.

    The mortality and morbidity of salmonella infections is seriously underestimated. Salmonella myocarditis is an unusual complication of salmonella sepsis in adults. Cases that do occur may be associated with high morbidity and mortality. We present a rare case of salmonella myocarditis with multi-organ failure in a previously healthy young adult man who was brought to the emergency room with fever, diarrhea, shortness of breath, and altered sensorium, discovered to have acute pulmonary edema and respiratory compromise for which he was assisted with mechanical ventilation for 8 days. Blood culture grew Salmonella typhi. Biochemically he exhibited myocardial, hepatic, and muscular enzymatic surge with renal failure, features of rhabdomyolysis, and disseminated intravascular coagulation. The patient showed a progressive improvement on treatment with ceftriaxone for 2 weeks in addition to decongestive therapy. He was discharged in good condition afterward. PMID:19944325

    A 15-year-old, unmarried female presented to our dermatology department for an intensely pruritic skin rash that had appeared abruptly 3 days earlier. She had a remarkable medical history for a case of allergic rhinitis and several attacks of asthma in her early childhood. The condition waxed and waned initially but had improved in recent years. Physical examination revealed several erythematous plaques, papules studded with scattered pustules having diameters less than 0.3 mm. Conspicuous scratch marks had caused erythematous wheal-like indurations also studded with pustules in a linear distribution across the waist, forearms (Fig. 1), and back (Fig. 2). Discrete papulopustules were present on the face, nape and neck. The patient was otherwise healthy. There were no other symptoms such as fever, malaise, weakness, or lymphadenopathy Laboratory results were normal for hepatic and renal functions, serum electrolytes, glucose, protein, erythrocyte sedimentation rate (8 mm/h), and C-reactive protein (0.355 mg/l). A human immunodeficiency virus (HIV) antibody screen test was negative. Serum was positive for herpes simplex virus (HSV)-1 and HSV-2 IgG (in low titers), but negative for HSV-1 and HSV-2 IgM. White blood cell count revealed leukocytosis (11.2 x 10(3)/l), with a differential count of 68% neutrophils, 27% lymphocytes, and 8% eosinophils. Serum IgA, IgG, and IgM were within normal limits, but the IgE level was elevated (677 mg/dl). Cultures from peripheral blood and pustules were negative. A Tzank smear performed on the pustules showed no multinucleated giant cells. Fungal testing of skin scrapings from the initial lesion site gave negative results. Routine stool tests, including common pathogen and parasite screens, were negative, and urinalysis results were unremarkable. A biopsy specimen obtained from a skin pustule showed subcorneal eosinophilic and neutrophilic pustules in the follicular infundibulum with marked spongiosis of the follicular epithelium

Casos clínicos: de 1997 a 2011 se diagnosticaron seis casos de abdomen agudo; en tres de ellos la enteritis eosinofílica causó necrosis irreversible de un segmento intestinal y hubo que practicar una resección intestinal segmentaria. En dos de ellos había un segmento intestinal con aspecto inflamatorio, que fue el único hallazgo causante del cuadro agudo y en los que sólo se practicó biopsia y otro caso donde fue un hallazgo sin relación con el proceso agudo. Conclusiones: la enteritis eosinofílica puede ocasionar cuadros de abdomen agudo que requieren intervención quirúrgica urgente. El aspecto intraoperatorio es el de un segmento con aspecto inflamatorio que puede llegar a ser macroscópicamente irreversible y donde sólo la resección parcial es el tratamiento correcto, que puede hacerse por vía laparoscópica.

    In eosinophilic esophagitis (EoE), diagnostic tests aid in the identification of pathophysiologic consequences and accurate detection of the disease. The EoE Endoscopic Reference Score (EREFS) classifies and grades the severity of the five major endoscopically identified esophageal features of EoE (edema, rings, exudates, furrows and strictures). The EREFS may be useful in the evaluation of disease severity and as an objective outcome of response to therapy. pH monitoring identifies the presence of abnormal degrees of acid exposure in the esophagus that characterizes gastroesophageal reflux disease. The presence of acid reflux, however, does not indicate that the reflux is responsible for esophageal eosinophilia. Esophageal manometry has not demonstrated a characteristic abnormality with sufficient sensitivity to make the test of diagnostic value in clinical practice. On the other hand, manometric characteristics of esophageal pressurization and longitudinal muscle dysfunction may help identify important pathophysiologic consequences of EoE. Esophageal impedance testing has demonstrated increased baseline mucosal impedance that correlates with increased epithelial permeability in EoE. Reduced mucosal integrity may provide intraluminal allergens access to antigen-presenting cells, serving as an early event in the pathogenesis of EoE. The functional luminal impedance probe (FLIP) provides quantitative assessment of esophageal mural compliance, a physiologic correlate of remodeling in EoE. Studies using FLIP have associated reductions in esophageal distensibility in EoE with the important outcome of food impaction risk. Finally, confocal endomicroscopy, multiphoton fluorescence microscopy and novel eosinophil-enhancing contrast agents are emerging methods that may allow for in vivo visualization of esophageal eosinophilic inflammation, thereby improving the detection and understanding of this emerging disease.

    Spinal cord injury (SCI) causes severe and long lasting motor and sensory deficits, chronic pain, and autonomic dysreflexia. (-)-epigallocatechin-3-gallate (EGCG) has shown to produce neuroprotective effect in a broad range of neurodegenerative disease animal models. This study designed to test the efficacy of intravenous infusion of EGCG for 36 h, in acutely injured rats' spinal cord: within first 4 h post-injury and, in chronically SC injured rats: after one year of injury. Functional outcomes measured using standard BBB scale, The Louisville Swim Scale (LSS) and, pain behavior assessment tests. 72 Female adult rats subjected to moderate thoracic SCI using MASCIS Impactor, blindly randomized as the following: (I) Acute SCI + EGCG (II) Acute SCI + saline. (III) Chronic SCI + EGCG. (IV) Chronic SCI + saline and, sham SCI animals. EGCG i.v. treatment of acute and, chronic SCI animals resulted in significantly better recovery of motor and sensory functions, BBB and LSS (P < 0.005) and (P < 0.05) respectively. Tactile allodynia, mechanical nociception (P < 0.05) significantly improved. Paw withdrawal and, tail flick latencies increase significantly (P < 0.05). Moreover, in the EGCG treated acute SCI animals the percentage of lesion size area significantly reduced (P < 0.0001) and, the number of neurons in the spinal cord increased (P < 0.001). Percent areas of GAP-43 and GFAP immunohistochemistry showed significant (P < 0.05) increase. We conclude that the therapeutic window of opportunity for EGCG to depict neurological recovery in SCI animals, is viable up to one year post SCI when intravenously infused for 36 h. PMID:24071567

    Eosinophil leukocytes have been reported to have a major role in host defense against invasive, migratory phases of helminth infestations, yet the relative larvicidal abilities of eosinophils and neutrophils have not been thoroughly examined. This study examined the killing of newborn (migratory phase) larvae of Trichinella spiralis during incubation by human granulocytes in vitro. The assay employed cultue of larvae with cells, sera, and reagents in microtiter wells with direct counting of surviving larvae after incubation. Killed larvae appeared to be lysed. Verification of the microplate assay was obtained by demonstrating complete loss of infectivity of larvae incubated with leukocytes and immune serum. In the presence of optimal immune serum concentrations, purified neutrophils or eosinophils achieved ≥95% killing of larvae at cell:larva ratios of 2,000:1 or greater. Fresh normal serum prompted slight (19%) killing by leukocytes at a cell:larva ratio of 9,000:1. Cells plus heat-inactivated normal serum and all sera preparations in the absence of leukocytes killed <8% of the larvae. The activity of immune serum was opsonic. Cells adhered to larvae that had been preincubated in immune serum, and immunofluorescent studies indicated that such preopsonized larvae were coated with immunoglobulin (Ig)G. However, preopsonized larvae lost opsonic activity and surface IgG during incubation for 3 h in medium lacking immune serum. The rate of killing was dependent on the cell:larva ratio; at high leukocyte concentrations (4,200:1), 99% were killed within 7 h; at lower cell:larva ratios, killing increased steadily during a 20-h incubation period. Killing was inhibited by 20 μg catalase, 5 μg/ml cytochalasin B, or 5μM colchicine, but was unchanged by superoxide dismutase and was enhanced by azide or cyanide. Leukocytes from a patient with chronic granulomatous disease, lacking ability to mount a normal oxidative response, demonstrated a markedly suppressed larvicidal

    Abstract Idiopathic hypereosinophilic syndrome (HES) is a condition of unknown origin characterized by clinical manifestations attributable to eosinophilia and eosinophilic infiltration of tissues. Cardiac involvement is rare and threatening accounting for 33% to 43% of death in HES. Management of pregnant patients with HES is challenging and have rarely been reported, particularly in the setting of heart failure. We here report on the case of a 29-year-old woman with HES who developed severe endomyocardial fibrosis with heart failure during pregnancy. Outcome was favorable under treatment with prednisone and azathioprine. This case illustrates a favorable outcome of endomyocardial fibrosis during pregnancy. PMID:26266372

    Lineage switch from AML to ALL is an extremely rare phenomenon, and we report the case of an adult diagnosed with AML at 46 years of age who relapsed with ALL. At initial diagnosis, blast cell morphology and immunophenotyping were consistent with the diagnosis of M4-AML. Complete remission was achieved, and the patient underwent autologous BMT. At relapse, six months after ABMT, blast cells were different from those seen at initial diagnosis, for morphology (L2-ALL), cytochemistry, and immunophenotyping. The karyotype was normal at both diagnosis and relapse. No evidence of bcr-abl fusion genes was found by RT-PCR. Monoclonal IgH and TCR gamma gene rearrangement were evidenced by PCR analysis at relapse but not on blast cells at AML diagnosis.

    Investigations into animal models of drug withdrawal have largely found that emotional signs of withdrawal (e.g. anxiety, anhedonia, and aversion) in adolescents are experienced earlier and less severely than in their adult counterparts. The majority of these reports have examined withdrawal from ethanol or nicotine. To expand our knowledge about the emotional withdrawal state in adolescent rats, we used potentiation of the acoustic startle reflex after an acute dose of morphine (10 mg/kg, subcutaneously) as a measure of opiate withdrawal. Startle was measured at four time points after morphine injection (2, 3, 4, and 5 h) in 28-day-old and 90-day-old male and female rats. The results of this experiment revealed that peak potentiation of the startle reflex occurred at 3 h in the adolescent rats and at 5 h in the adult rats, and that the magnitude of withdrawal was larger in the adults. No sex differences were observed. Overall, these results affirm that, similar to withdrawal from ethanol and nicotine, opiate withdrawal signs are less severe in adolescent than in adult rats.

  11. Acute stress differentially affects aromatase activity in specific brain nuclei of adult male and female quail.

    The rapid and temporary suppression of reproductive behavior is often assumed to be an important feature of the adaptive acute stress response. However, how this suppression operates at the mechanistic level is poorly understood. The enzyme aromatase converts testosterone to estradiol in the brain to activate reproductive behavior in male Japanese quail (Coturnix japonica). The discovery of rapid and reversible modification of aromatase activity (AA) provides a potential mechanism for fast, stress-induced changes in behavior. We investigated the effects of acute stress on AA in both sexes by measuring enzyme activity in all aromatase-expressing brain nuclei before, during, and after 30 min of acute restraint stress. We show here that acute stress rapidly alters AA in the male and female brain and that these changes are specific to the brain nuclei and sex of the individual. Specifically, acute stress rapidly (5 min) increased AA in the male medial preoptic nucleus, a region controlling male reproductive behavior; in females, a similar increase was also observed, but it appeared delayed (15 min) and had smaller amplitude. In the ventromedial and tuberal hypothalamus, regions associated with female reproductive behavior, stress induced a quick and sustained decrease in AA in females, but in males, only a slight increase (ventromedial) or no change (tuberal) in AA was observed. Effects of acute stress on brain estrogen production, therefore, represent one potential way through which stress affects reproduction.

    This study compared the effects of a bout of maximal running exercise on arterial stiffness in children and adults. Right carotid blood pressure and artery stiffness indices measured by pulse wave velocity (PWV), compliance and distensibility coefficients, stiffness index α and β (echo-tracking), contralateral carotid blood pressure, and upper and lower limb and central/aortic PWV (applanation tonometry) were taken at rest and 10 min after a bout of maximal treadmill running in 34 children (7.38 ± 0.38 years) and 45 young adults (25.22 ± 0.91 years) having similar aerobic potential. Two-by-two repeated measures analysis of variance and analysis of covariance were used to detect differences with exercise between groups. Carotid pulse pressure (PP; η(2) = 0.394) increased more in adults after exercise (p < 0.05). Compliance (η(2) = 0.385) decreased in particular in adults and in those with high changes in distending pressure, similarly to stiffness index α and β. Carotid PWV increased more in adults and was related to local changes in PP but not mean arterial pressure (MAP). Stiffness in the lower limbs decreased (η(2) = 0.115) but apparently only in those with small MAP changes (η(2) = 0.111). No significant exercise or group interaction effects were found when variables were adjusted to height. An acute bout of maximal exercise can alter arterial stiffness and hemodynamics in the carotid artery and within the active muscle beds. Arterial stiffness and hemodynamic response to metabolic demands during exercise in children simply reflect their smaller body size and may not indicate a particular physiological difference compared with adults.

    Background Eosinophilic meningoencephalitis caused by the helminth Angiostrongylus cantonensis, is an emerging infectious disease in America. The objective of this paper was to determine if the intrathecal synthesis of immunoglobulin E is produced during the acute phase of the disease. Methods Thirteen patients, mean age 4.5 years were studied; a diagnostic lumbar puncture was performed and serum samples taken. Immunoglobulin E (IgE) in serum and in cerebrospinal fluid (CSF) was quantified by nephelometry. Control patients had other infections or other neurological diseases. Results The mean cell count in the CSF was 500 × 10-6 cells/L and of these 23% were eosinophils. In blood the eosinophils were 13%. The chief symptoms of the patients were migraine, vomiting and fever and 50% presented some meningeal signs. IgE intrathecal synthesis analyzed by the corresponding quotient diagram (Reibergram) was observed in all patients. No intrathecal IgE synthesis was seen in control patients. Conclusion Intrathecal synthesis of IgE demonstrates the participation of this immunoglobulin in the destruction of the third stage larvae of the parasite in the CSF. The test should be considered in our environment as a tool to aid diagnosis. PMID:19032790

    Meningoencephalitis is an acute inflammation of the brain and spinal cord & their covering protective membranes. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency. The commonest symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light (photophobia) or loud noises (phonophobia). Children often exhibit only nonspecific symptoms, such as irritability and drowsiness. If a rash is present, it may indicate a particular cause of meningitis; for instance, meningitis caused by meningococcal bacteria may be accompanied by a characteristic rash. A broad variety of allergic, infectious, neoplastic, and idiopathic diseases are associated with increased blood and/or tissue eosinophilia and range in severity from self-limited conditions to life-threatening disorders. Although accepted upper limits of normal blood eosinophil numbers vary somewhat, a value above 600 eosinophils /microL of blood is abnormal in the vast majority of cases. Generally speaking, there are several possible causes of eosinophils in the CSF; undoubtedly parasitic infection is one of the main causes. PMID:27363042

    Ultrastructural evaluation of eosinophilic leukocytes from a 2-yr-old asymptomatic girl with chronic benign neutropenia (CBN) revealed a variety of morphological abnormalities. All eosinophils obtained from blood and marrow specimens contained multipole microcrystalloids in most of the mature cytoplasmic granules. An increase in crystalloid-free, immature granules in late (bilobed nuclei) eosinophils suggested a delay in granule maturation. The eosinophil granules appeared to be of normal size and demonstrated normal acid phosphatase reactivity. Eosinophilic myelocytes contained abnormal cisternae of rough endoplasmic reticulum (RER) and lacked abundant elongated RER cisternae seen in normal cells. A few eosinophilic myelocytes in specimens of bone marrow from the child contained large intranuclear crystalloids measuring up to 3 mu in length. The intranuclear crystalloid contained as cubic lattice of dense material with a periodicity similar to that described for cytoplasmic crystalloids. The ultrastructural morphology of marrow neutrophils was normal, as described in other cases of CBN. Ultrastructural examination of blood eosinophils from the father demonstrated microcrystalloids in cytoplasmic granules identical to those seen in the child. The father was asymptomatic and had normal leukocyte counts. Thus, anomalous crystalloid granule genesis occurred in the father and daughter and was not necessarily associated with neutropenia or clinical symptomatology. This anomaly is associated with the accumulation of intranuclear crystalloid material in eosinophilic myelocytes, which do not appear to be released from the marrow compartment. PMID:7306702

    Norovirus (NoV) infections that cause acute gastroenteritis are commonly observed during colder months. This study was conducted to investigate the clinical features and molecular epidemiology of NoVs in adult outpatients with acute gastroenteritis in Beijing, China from August 2008 to July 2009. Five hundred nineteen patients were enrolled, their stool specimens were collected, and 136 (26.2%) were positive for NoV. The elderly were found to be more susceptible to NoVs than other age groups. The greatest number of gastroenteritis cases associated with occurred in October. Six GI and eleven GII NoV genotypes were isolated; among these, the GII.4 genotype was most prevalent (70/140 and 50% were the 2006b variant). The elderly were more susceptible to the GII.4 genotype than to other genotypes. Greater numbers of neutrophils in the peripheral blood were observed in the NoV infected group than in uninfected control group. However, the levels of neutrophils and leukocytes in the non-GII.4 patients infected with NoV were higher than those of the GII.4-infected patients. The data highlight the role of NoV as a primary agent responsible for gastroenteritis in adults in Beijing, China.

    Accurate assessment of residual disease is important for the prediction of outcome in patients with acute leukaemia in complete remission (CR). To investigate whether abnormalities on magnetic resonance (MR) images of femoral marrow in adult patients with acute myeloid leukaemia (AML) in CR can predict outcome, 28 newly diagnosed patients with AML underwent MR imaging when bone marrow aspiration or biopsy was performed to verify the state of CR after induction therapy. MR abnormalities on short TI (inversion time) inversion recovery (STIR) techniques persisted in all four patients who did not achieve CR. In 13 CR patients abnormalities on STIR images resolved, to result in normal appearance at the time CR was achieved. All 13 patients remained in CR for 3-104 months (median, 73 months). In the other 11 CR patients, STIR abnormalities persisted at the time CR was achieved. Seven of them relapsed between 1 and 28 months (median, 3 months) after MR evaluation. Disease-free survival of patients with persistent abnormal STIR images was significantly shorter than that of patients with normal STIR images (P < 0.01). MR imaging of femoral marrow may predict outcome in adult patients with AML in CR. PMID:11918535

    The factors responsible for the conjunctivitis and iritis associated with acute ocular infection and post enteric inflammatory disease are not fully known. The pro-inflammatory activity of unilateral topical application of muramyl dipeptide (MDP; the smallest bio-active Gram-positive and Gram-negative bacterial cell wall component) was investigated in adult rabbits. The resultant bilateral conjunctivitis/iritis and pyogenic responses were characterized. Bilateral symptoms were graded by slit lamp examinations; tear fluid, Schirmer tests (tear production), blood and aqueous humor (AH) samples were obtained from MDP-treated and untreated rabbits. MDP concentration, gamma-glutamyltranspeptidase activity (GGT; key enzyme in glutathione recapture, xenobiotic detoxification, eicosanoid synthesis and neutrophil function), protein concentration, and tear cell density, cytology, and immunofluorescent antibody reactivity to GGT and calreticulin (CRT; MDP-binding protein) were determined. MDP was cleared from ipsilateral tears and serum by 6 h, but was undetected in mock-treated contralateral tears. Bilateral signs of acute transient pyogenic conjunctivitis, characterized by tearing, lid edema, conjunctival hyperemia, chemosis and leukocytic infiltrate with iritis (erythema and aqueous flare) were detected. Milder symptoms occurred in the mock-treated contralateral eyes. Bilateral symptoms, tear production, tear protein, GGT activity, and mucopurulent discharge (containing up to 2.5-5.0 × 10(6) cells/mL) were elevated 4-8 h post MDP and resolved to near pre-treatment levels by 24 h. Tear GGT activity and protein levels were higher in MDP-treated and mock-treated contralateral eyes than in eyes of untreated adult rabbits (p's < 0.001). Elevated tear GGT activity was associated with histopathology and increased vascular and epithelial permeability to serum protein, GGT-positive epithelia cells, macrophages and heterophils.

Posttreatment, treatment group CD3+, CD4+, CD4+/CD8+, natural killer (NK) cell, and immunoglobulin (IgG, IgA, and IgM) levels were significantly higher than those of the control group (p < 0.05), and CD8+ levels were lower in the treatment group than in the control group (p < 0.05). Treatment group interleukin- (IL-) 4 and IL-10 levels were significantly higher compared to the control posttreatment (both p < 0.05) as were complete remission, overall response, and quality of life (QoL) improvement rates (p < 0.05). The control group had more incidences of grade 3/4 hematologic and nonhematologic toxicity (p < 0.05). Responses to induction chemotherapy, QoL improvement, and adverse events incidence between control group patients with acute myeloid leukemia and acute lymphocytic leukemia were not significantly different. CKI plus standard induction chemotherapy is effective and safe for treating AL, possibly by increasing immunologic function. PMID:27738441

    Junctional epidermolysis bullosa (JEB) is a rare genodermatosis characterized by a split in the lamina lucida usually because of mutations in LAMA3, LAMB3 and LAMC2 resulting in absence or reduction of laminin-332. Rare subtypes of JEB have mutations in COL17A1, ITGB4, ITGA6 and ITGA3 leading to reduction or dysfunction of collagen XVII, integrin α6β4 and integrin α3. The classic finding under light microscopy is a paucicellular, subepidermal split. We describe the unusual presence of an eosinophilic infiltrate in the bullae and subjacent dermis in a neonate with JEB, generalized intermediate (formerly known as non-Herlitz-type JEB), discuss the histologic differential diagnosis for a subepidermal blister in a neonate, review the literature regarding cases of epidermolysis bullosa (EB) presenting with inflammatory infiltrates, and discuss mechanisms to explain these findings. This case highlights that eosinophils can rarely be seen in EB and should not mislead the dermatopathologist into diagnosing an autoimmune blistering disorder. PMID:25950805

    The current incidence estimate of 40 traumatic spinal cord injuries (TSCI) per million population/year in the United States (U.S.) is based on data from the 1990s. We sought to update the incidence and epidemiology of TSCI in U.S adults by using the Nationwide Emergency Department Sample (NEDS), the largest all-payer emergency department (ED) database in the United States. Adult ED visits between 2007 and 2009 with a principal diagnosis of TSCI were identified using International Classification of Diseases (ICD)-9 codes (806.0-806.9 and 952.0-952.9). We describe TSCI cumulative incidence, mortality, discharge disposition, and hospital charges weighted to the U.S. population. The estimated 3-year cumulative incidence of TSCI was 56.4 per million adults. Cumulative incidence of TSCI in older adults increased from 79.4 per million older adults in 2007 to 87.7 by the end of 2009, but remained steady among younger adults. Overall, falls were the leading cause of TSCI (41.5%). ED charges rose by 20% over the study period, and death occurred in 5.7% of patients. Compared with younger adults, older adults demonstrated higher adjusted odds of mortality in the ED (adjusted odds ratio [AOR]=4.4; 95% confidence interval [CI]: 1.1-16.6), mortality during hospitalization (AOR=5.9; 95% CI: 4.7-7.4), and being discharged to chronic care (AOR=3.7; 95% CI: 3.0-4.5). The incidence of TSCI is higher than previously reported with a progressive increase among older adults who also experience worse outcomes compared with younger adults. ED-related TSCI charges are also increasing. These updated national estimates support the development of customized prevention strategies based on age-specific risk factors.

    In developing country like India arsenic poisoning is a major public health problem. Association of chronic eosinophilic pneumonia and chronic diarrhea with arsenicosis is rare. Also pulmonary cavity formation in chronic eosinophilic pneumonia is very uncommon. A 44-year-old male patient, resident of an arsenic affected area was admitted for evaluation of chronic diarrhoea, persistent peripheral eosinophilia along with radiologically visible cavity in right upper zone. There were dermatological manifestations of arsenicosis along with presence of noncirrhotic portal fibrosis and peripheral eosinophilia. On bronchoalveolar lavage study, eosinophil comprised 40% of total cellularity making the diagnosis of chronic eosinophilic pneumonia. After ruling out all possible causes of diarrhoea and chronic eosinophilic pneumonia, we came to conclusion that arsenic could be implicated as causative agent.

    The multiplication of two strains of Plasmodium falciparum in culture, as measured by [3H]hypoxanthine incorporation, was inhibited in a dose-dependent manner by granule proteins secreted by purified eosinophils obtained from patients with the hypereosinophilic syndrome. Morphological examination revealed the presence of abnormal parasites inside erythrocytes, indicating that they were killed in situ, and the later stages of the developmental cycle were found to be most susceptible to these toxic effects. A monoclonal antibody against eosinophil cationic protein partially blocked the inhibitory effect, suggesting that it was caused by more than one of the eosinophil granule proteins. Thus some of the antimalarial effects of molecules such as the tumor necrosis factor, which activates eosinophils, may be mediated through the enhanced production of eosinophil secretion products.

    Eosinophilic esophagitis (EoE) is a chronic immune-mediated condition believed to have an allergic component, but the timing of the initial allergen triggers that cause the disease is poorly understood. While the clinical presentation of EoE is often of longstanding symptoms, in animal models, acute exposure to an allergen challenge successfully produces EoE. In this report, we present three cases of individuals who developed esophageal eosinophilia and EoE shortly after a clearly identified exposure to aeroallergens. These cases highlight the allergic etiology of EoE, and provide a link from humans to the previously described experimental mechanisms. PMID:23799220

    Double cord blood transplantation extends the use of cord blood to adults for whom a single unit is not available, but the procedure is limited by its cost. To evaluate outcomes and cost-effectiveness of double compared to single cord blood transplantation, we analyzed 134 transplants in adults with acute leukemia in first remission. Transplants were performed in France with reduced intensity or myeloablative conditioning regimens. Costs were estimated from donor search to 1 year after transplantation. A Markov decision analysis model was used to calculate quality-adjusted life-years and cost-effectiveness ratio within 4 years. The overall survival at 2 years after single and double cord blood transplants was 42% versus 62%, respectively (P=0.03), while the leukemia-free-survival was 33% versus 53%, respectively (P=0.03). The relapse rate was 21% after double transplants and 42% after a single transplant (P=0.006). No difference was observed for non-relapse mortality or chronic graft-versus-host-disease. The estimated costs up to 1 year after reduced intensity conditioning for single and double cord blood transplantation were € 165,253 and €191,827, respectively. The corresponding costs after myeloablative conditioning were € 192,566 and € 213,050, respectively. Compared to single transplants, double cord blood transplantation was associated with supplementary costs of € 21,302 and € 32,420 up to 4 years, but with increases in quality-adjusted life-years of 0.616 and 0.484, respectively, and incremental cost-effectiveness ratios of € 34,581 and €66,983 in the myeloablative and reduced intensity conditioning settings, respectively. Our results showed that for adults with acute leukemia in first complete remission in France, double cord transplantation is more cost-effective than single cord blood transplantation, with better outcomes, including quality-adjusted life-years.

    The outcomes of adult acute lymphoblastic leukemia (ALL) patients with chemotherapy or autologous hematopoietic stem cell transplantation (HSCT) are unsatisfactory. Therefore, allogeneic (allo) HSCT has been applied to those patients in first complete remission (CR1), and has shown a long-term survival rate of approximately 50 %. In terms of myeloablative conditioning (MAC) regimen, higher dose of cyclophosphamide (CY) and total body irradiation (TBI) (the standard CY + TBI) has been generally applied to allo HSCT. Other MAC regimens such as busulfan-based or etoposide-based regimens have also been used. Among those, medium-dose etoposide (ETP) in addition to the standard CY + TBI conditioning regimen appears to be promising for allo HSCT in adult ALL when transplanted in ALL patients aged under 50 years in CR1 and also in CR2, showing an excellent outcome without increasing relapse or transplant-related mortality (TRM) rates. By contrast, reduced-intensity conditioning (RIC) regimens have also been applied to adult ALL patients and favorable outcomes have been obtained; however, relapse and TRM rates remain high. Therefore, an allo HSCT conditioning regimen which deserves further study for adult ALL patients aged under 50 years in CR1 and CR2 appears to be medium-dose ETP + CY + TBI and RIC is suitable for patients aged over 50 years or for younger patients with comorbid conditions. On the contrary, new therapeutic strategies for adult ALL patients are increasingly utilized with better outcomes; namely, various tyrosine kinase inhibitors for Philadelphia chromosome (Ph)-positive ALL, human leukocyte antigen-haploidentical HSCT, and pediatric-inspired regimens for Ph-negative ALL. Therefore, the optimal treatment modality should be selected considering patient's age, Ph-positivity, donor availability, risk classification, efficacy, and safety. PMID:26322249

The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region.

    Acute kidney injury after cardiac surgery with cardiopulmonary bypass is a common and serious complication and it is associated with increased morbidity and mortality. Diagnosis of acute kidney injury is based on the serum creatinine levels which rise several hours to days after the initial injury. Thus, novel biomarkers that will enable faster diagnosis are needed in clinical practice. There are numerous urine and serum proteins that indicate kidney injury and are under extensive research. Despite promising basic research results and assembled data, which indicate superiority of some biomarkers to creatinine, we are still awaiting clinical application. PMID:27212976

    Background: Electroconvulsive seizure treatment is a fast-acting antidepressant therapy that evokes rapid transcriptional, neurogenic, and behavioral changes. Epigenetic mechanisms contribute to altered gene regulation, which underlies the neurogenic and behavioral effects of electroconvulsive seizure. We hypothesized that electroconvulsive seizure may modulate the expression of epigenetic machinery, thus establishing potential alterations in the epigenetic landscape. Methods: We examined the influence of acute and chronic electroconvulsive seizure on the gene expression of histone modifiers, namely histone acetyltransferases, histone deacetylases, histone methyltransferases, and histone (lysine) demethylases as well as DNA modifying enzymes, including DNA methyltransferases, DNA demethylases, and methyl-CpG-binding proteins in the hippocampi of adult male Wistar rats using quantitative real time-PCR analysis. Further, we examined the influence of acute and chronic electroconvulsive seizure on global and residue-specific histone acetylation and methylation levels within the hippocampus, a brain region implicated in the cellular and behavioral effects of electroconvulsive seizure. Results: Acute and chronic electroconvulsive seizure induced a primarily unique, and in certain cases bidirectional, regulation of histone and DNA modifiers, and methyl-CpG-binding proteins, with an overlapping pattern of gene regulation restricted to Sirt4, Mll3, Jmjd3, Gadd45b, Tet2, and Tet3. Global histone acetylation and methylation levels were predominantly unchanged, with the exception of a significant decline in H3K9 acetylation in the hippocampus following chronic electroconvulsive seizure. Conclusions: Electroconvulsive seizure treatment evokes the transcriptional regulation of several histone and DNA modifiers, and methyl-CpG-binding proteins within the hippocampus, with a predominantly distinct pattern of regulation induced by acute and chronic electroconvulsive seizure.

    Outcomes after unmanipulated haploidentical stem cell transplantation (Haplo) and after unrelated cord blood transplantation (UCBT) are encouraging and have become alternative options to treat patients with high-risk acute leukemia without human leukocyte antigen (HLA) matched donor. We compared outcomes after UCBT and Haplo in adults with de novo acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Median follow-up was 24 months. Analysis was performed separately for patients with AML, n=918 (Haplo=360, UCBT=558) and ALL, n=528 (Haplo=158 and UCBT=370). UCBT was associated with delayed engraftment and higher graft failure in both AML and ALL recipients. In multivariate analysis, UCBT was associated with lower incidence of chronic graft-vs-host disease both in the AML group (hazard ratio (HR)=0.63, P=0.008) and in the ALL group (HR=0.58, P=0.01). Not statistically significant differences were observed between Haplo and UCBT for relapse incidence (HR=0.95, P=0.76 for AML and HR=0.82, P=0.31 for ALL), non-relapse mortality (HR=1.16, P=0.47 for AML and HR=1.23, P=0.23 for ALL) and leukemia-free survival (HR 0.78, P=0.78 for AML and HR=1.00, P=0.84 for ALL). There were no statistically differences on main outcomes after unmanipulated Haplo and UCBT, and both approaches are valid for acute leukemia patients lacking a HLA matched donor. Both strategies expand the donor pool for patients in need.

    Astronauts on multi-year interplanetary missions will be exposed to a low, chronic dose of high-energy, high-charge particles. Studies in rodents show acute, nonfractionated exposure to these particles causes brain changes such as fewer adult-generated hippocampal neurons and stem cells that may be detrimental to cognition and mood regulation and thus compromise mission success. However, the influence of a low, chronic dose of these particles on neurogenesis and stem cells is unknown. To examine the influence of galactic cosmic radiation on neurogenesis, adult-generated stem and progenitor cells in Nestin-CreER(T2)/R26R-YFP transgenic mice were inducibly labeled to allow fate tracking. Mice were then sham exposed or given one acute 100 cGy (56)Fe-particle exposure or five fractionated 20 cGy (56)Fe-particle exposures. Adult-generated hippocampal neurons and stem cells were quantified 24 h or 3 months later. Both acute and fractionated exposure decreased the amount of proliferating cells and immature neurons relative to sham exposure. Unexpectedly, neither acute nor fractionated exposure decreased the number of adult neural stem cells relative to sham expsoure. Our findings show that single and fractionated exposures of (56)Fe-particle irradiation are similarly detrimental to adult-generated neurons. Implications for future missions and ground-based studies in space radiation are discussed. PMID:24320054

    The prognosis of adult patients with relapsed acute lymphoblastic leukemia (ALL) remains poor. Recent studies in adolescents and young adults reported better outcomes when therapy was intensified. Based on hyper-CVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) as a backbone, we designed an augmented version with intensified doses of vincristine, dexamethasone, and asparaginase (L-asparaginase in the first 62 patients and pegaspargase in the remainder) starting from course 1. Ninety patients have been enrolled, with a median age of 34 years (range, 14-70 years). Most patients (78%) had pre-B ALL and were in first salvage (76%), with a first remission duration of 12.6 months (range, 1-78 months). Ten patients had primary refractory disease. Of 88 evaluable patients, 41 (47%) achieved complete remission (CR), with a median time to CR of 29 days (range, 18-80 days). Eight patients (9%) died within the first 30 days. Median CR duration, progression-free survival, and overall survival were 5, 6.2, and 6 months, respectively. Median overall survival of CR patients was 10.2 months (range, 1.4-69.5+ months). Twenty-eight patients (32%) proceeded to stem cell transplantation. Myelosuppression-associated complications were frequent. Pegaspargase was equally effective and easier to administer than L-asparaginase. Augmented hyper-CVAD may be suitable to be studied in younger adults with untreated ALL. PMID:21454191

    Stressful experiences modify activity in areas of the brain involved in the rewarding effects of psychostimulants. In the present study we evaluated the influence of acute social defeat (ASD) on the conditioned rewarding effects of cocaine in adolescent (PND 29-32) and adult (PND 50-53) male mice in the conditioned place preference (CPP) paradigm. Experimental mice were exposed to social defeat in an agonistic encounter before each session of conditioning with 1mg/kg or 25mg/kg of cocaine. The effects of social defeat on corticosterone levels were also evaluated. Adult mice exposed to ASD showed an increase in the conditioned reinforcing effects of cocaine. Only these mice developed cocaine-induced CPP with the subthreshold dose of cocaine, and they needed a higher number of extinction sessions for the 25mg/kg cocaine-induced CPP to be extinguished. In adolescent mice, on the other hand, ASD reduced the conditioned reinforcing effects of cocaine, since CPP was not produced with the lower dose of cocaine and was extinguished faster when they were conditioned with 25mg/kg. Adult mice exposed to social defeat displayed higher levels of corticosterone than their controls and adolescent mice. Our results confirm that the effect of social defeat stress on the acquisition and reinstatement of the CPP induced by cocaine varies depending on the age at which this stress is experienced.

    Manganese chloride (MnCl2) is capable of stimulating luteinizing hormone releasing hormone (LHRH) secretion in adult male Sprague-Dawley rats through the activation of the hypothalamic nitric oxide/cyclic guanosine monophosphate (cGMP)/protein kinase G pathway. The present study aimed to determine the involvement of specific neurotransmitters involved in this action. Our results indicate that dopamine, but not glutamic acid and prostaglandinds, mediates the MnCl2 stimulated secretion of LHRH from medial basal hypothalami in vitro, as well as increases the activity of nitric oxide synthase. Furthermore, a biphasic response was observed in that gamma aminobutyric acid (GABA) release was also increased, which acts to attenuate the MnCl2 action to stimulate LHRH secretion. Although it is clear that manganese (Mn+2) can acutely induce LHRH secretion in adult males, we suggest that the additional action of MnCl2 to release GABA, a LHRH inhibitor, may ultimately contribute to suppressed reproductive function observed in adult animals following exposure to high chromic levels of Mn+2.

    The effects of acute aerobic exercise on cognitive functions in humans have been the subject of much investigation; however, these studies are limited by several factors, including a lack of randomized controlled designs, focus on only a single cognitive function, and testing during or shortly after exercise. Using a randomized controlled design, the present study asked how a single bout of aerobic exercise affects a range of frontal- and medial temporal lobe-dependent cognitive functions and how long these effects last. We randomly assigned 85 subjects to either a vigorous intensity acute aerobic exercise group or a video watching control group. All subjects completed a battery of cognitive tasks both before and 30, 60, 90, or 120 min after the intervention. This battery included the Hopkins Verbal Learning Test-Revised, the Modified Benton Visual Retention Test, the Stroop Color and Word Test, the Symbol Digit Modalities Test, the Digit Span Test, the Trail Making Test, and the Controlled Oral Word Association Test. Based on these measures, composite scores were formed to independently assess prefrontal cortex- and hippocampal-dependent cognition. A three-way mixed Analysis of Variance was used to determine whether differences existed between groups in the change in cognitive function from pre- to post-intervention testing. Acute exercise improved prefrontal cortex- but not hippocampal-dependent functioning, with no differences found between delay groups. Vigorous acute aerobic exercise has beneficial effects on prefrontal cortex-dependent cognition and these effects can last for up to 2 hr after exercise.

  6. Autologous stem cell transplantation versus alternative allogeneic donor transplants in adult acute leukemias.

    The study aims to provide an updated assessment of the evidence for individual pharmacological therapies for acute migraine treatment. Pharmacological therapy is frequently required for acutely treating migraine attacks. The American Academy of Neurology Guidelines published in 2000 summarized the available evidence relating to the efficacy of acute migraine medications. This review, conducted by the members of the Guidelines Section of the American Headache Society, is an updated assessment of evidence for the migraine acute medications. A standardized literature search was performed to identify articles related to acute migraine treatment that were published between 1998 and 2013. The American Academy of Neurology Guidelines Development procedures were followed. Two authors reviewed each abstract resulting from the search and determined whether the full manuscript qualified for review. Two reviewers studied each qualifying full manuscript for its level of evidence. Level A evidence requires at least 2 Class I studies, and Level B evidence requires 1 Class I or 2 Class II studies. The specific medications - triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan [oral, nasal spray, injectable, transcutaneous patch], zolmitriptan [oral and nasal spray]) and dihydroergotamine (nasal spray, inhaler) are effective (Level A). Ergotamine and other forms of dihydroergotamine are probably effective (Level B). Effective nonspecific medications include acetaminophen, nonsteroidal anti-inflammatory drugs (aspirin, diclofenac, ibuprofen, and naproxen), opioids (butorphanol nasal spray), sumatriptan/naproxen, and the combination of acetaminophen/aspirin/caffeine (Level A). Ketoprofen, intravenous and intramuscular ketorolac, flurbiprofen, intravenous magnesium (in migraine with aura), and the combination of isometheptene compounds, codeine/acetaminophen and tramadol/acetaminophen are probably effective (Level B).

    Brief neonatal handling permanently alters hypothalamic-pituitary-adrenal axis function resulting in increased ability to cope with stress. Since stress is known to affect cognitive abilities, in the present study we investigated the effect of brief (15 min) handling on learning and memory in the Morris water maze, following exposure to an acute restraint stress either before training or recall. Exposure of non-handled rats to the acute stress prior to training resulted in quicker learning of the task, than in the absence of the stressor. When acute stress preceded acquisition, male handled rats showed an overall better learning performance, and both sexes of handled animals were less impaired in the subsequent memory trial, compared to the respective non-handled. In addition, the number of neurons immunoreactive for GR was higher in all areas of Ammon's horn of the handled rats during the recall. In contrast, the number of neurons immunoreactive for MR was higher in the CA1 and CA2 areas of the non-handled males. When the acute restraint stress was applied prior to the memory test, neonatal handling was not effective in preventing mnemonic impairment, as all animal groups showed a similar deficit in recall. In this case, no difference between handled and non-handled rats was observed in the number of GR positive neurons in the CA2 and CA3 hippocampal areas during the memory test. These results indicate that early experience interacts with sex and acute stress exposure in adulthood to affect performance in the water maze. Hippocampal corticosterone receptors may play a role in determining the final outcome.

    Background Stress and stress hormones modulate memory formation in various ways that are relevant to our understanding of stress-related psychopathology, such as posttraumatic stress disorder (PTSD). Particular relevance is attributed to efficient memory formation sustained by the hippocampus and parahippocampus. This process is thought to reduce the occurrence of intrusions and flashbacks following trauma, but may be negatively affected by acute stress. Moreover, recent evidence suggests that the efficiency of visuo-spatial processing and learning based on the hippocampal area is related to PTSD symptoms. Objective The current study investigated the effect of acute stress on spatial configuration learning using a spatial contextual cueing task (SCCT) known to heavily rely on structures in the parahippocampus. Method Acute stress was induced by subjecting participants (N = 34) to the Maastricht Acute Stress Test (MAST). Following a counterbalanced within-subject approach, the effects of stress and the ensuing hormonal (i.e., cortisol) activity on subsequent SCCT performance were compared to SCCT performance following a no-stress control condition. Results Acute stress did not impact SCCT learning overall, but opposing effects emerged for high versus low cortisol responders to the MAST. Learning scores following stress were reduced in low cortisol responders, while high cortisol-responding participants showed improved learning. Conclusions The effects of stress on spatial configuration learning were moderated by the magnitude of endogenous cortisol secretion. These findings suggest a possible mechanism by which cortisol responses serve an adaptive function during stress and trauma, and this may prove to be a promising route for future research in this area.

    There is much interest in the mechanisms that regulate adult tissue homeostasis and their relationship to processes governing foetal development. Mice deleted for the Wilms' tumour gene, Wt1, lack kidneys, gonads, and spleen and die at mid-gestation due to defective coronary vasculature. Wt1 is vital for maintaining the mesenchymal–epithelial balance in these tissues and is required for the epithelial-to-mesenchyme transition (EMT) that generates coronary vascular progenitors. Although Wt1 is only expressed in rare cell populations in adults including glomerular podocytes, 1% of bone marrow cells, and mesothelium, we hypothesised that this might be important for homeostasis of adult tissues; hence, we deleted the gene ubiquitously in young and adult mice. Within just a few days, the mice suffered glomerulosclerosis, atrophy of the exocrine pancreas and spleen, severe reduction in bone and fat, and failure of erythropoiesis. FACS and culture experiments showed that Wt1 has an intrinsic role in both haematopoietic and mesenchymal stem cell lineages and suggest that defects within these contribute to the phenotypes we observe. We propose that glomerulosclerosis arises in part through down regulation of nephrin, a known Wt1 target gene. Protein profiling in mutant serum showed that there was no systemic inflammatory or nutritional response in the mutant mice. However, there was a dramatic reduction in circulating IGF-1 levels, which is likely to contribute to the bone and fat phenotypes. The reduction of IGF-1 did not result from a decrease in circulating GH, and there is no apparent pathology of the pituitary and adrenal glands. These findings 1) suggest that Wt1 is a major regulator of the homeostasis of some adult tissues, through both local and systemic actions; 2) highlight the differences between foetal and adult tissue regulation; 3) point to the importance of adult mesenchyme in tissue turnover.

    Eosinophilic myocarditis (EM) is a rare form of myocarditis that usually presents with heart failure due to eosinophilic infiltration. EM is often a component of hypereosinophilic syndrome (HES). HES is a rare disorder characterized by persistent, marked eosinophilia combined with organ system dysfunction. A 38-year-old man was admitted to emergency services with left inguinal pain and fever, and was hospitalized with diagnosis of nephrolithiasis and urinary tract infection. Intravenous antibiotic therapy of 3 grams meropenem per day and analgesic of 50 mg pethidine per day were administered. Typical angina pectoris and dyspnea developed approximately 24 hours after treatment. Rash on the chest, and diminished bilateral lung sounds and rales were observed. Nonspecific changes were present on electrocardiogram. Laboratory analysis showed progressively increasing levels of cardiac biomarkers and eosinophilia. Peripheral blood smear, bone marrow aspiration, and biopsy demonstrated eosinophilia. Chest x-ray revealed diffuse, bilateral interstitial and reticulonodular infiltrates. Transthoracic echocardiography showed thickened left ventricle. Coronary angiography revealed normal coronary arteries. EM was suspected, endomyocardial biopsy was performed, and pathologic specimen confirmed the diagnosis. Corticosteroid treatment was initiated, and within 1 day, angina pectoris and dyspnea had dramatically reduced, and cardiac biomarkers and eosinophil count had decreased. Normal chest x-ray was observed after 72 hours. The patient was discharged with steroid treatment. PMID:27665334

    Yawning is a familiar and phylogenetically widespread phenomenon, but no consensus exists regarding its functional significance. We tested the hypothesis that yawning communicates to others a transition from a state of physiological and/or psychological arousal (for example, due to action of a stressor) to a more relaxed state. This arousal reduction hypothesis predicts little yawning during arousal and more yawning (above baseline) during and after down-regulation of arousal. Experimental capture-restraint tests with wild adult Nazca boobies (Sula granti), a seabird, increased yawning frequency after release from restraint, but yawning was almost absent during tests. Natural maltreatment by non-parental adults also increased yawning by nestlings, but only after the maltreatment ended and the adult left. CORT (corticosterone) was a logical a priori element of the stress response affecting the stressor-yawning relationship under the arousal reduction hypothesis, and cannot be excluded as such for adults in capture-restraint tests but is apparently unimportant for nestlings being maltreated by adults. The arousal reduction hypothesis unites formerly disparate results on yawning: its socially contagious nature in some taxa, its clear pharmacological connection to the stress response, and its temporal linkage to transitions in arousal between consciousness and sleep.

    Background and Objectives: An increase in the consumption of smokeless tobacco has been noticed among high school, college students, and adults. Despite the antiquity and popularity of chewing tobacco in India, its effects have not been investigated systematically in humans. The aim of this study was to investigate acute effects of gutkha chewing on heart rate variability (HRV) among healthy young adults. Materials and Methods: A total of 60 young adult males were included in the study. Each individual was asked to chew tobacco and subjected to HRV analysis. HRV analysis using short-term electrocardiogram recording was used to measure HRV parameters before gutkha chewing and at 5, 15, and 30 min after chewing tobacco. One-way analysis of variance and paired t-test was used to assess changes over time. Results: There was a significant increase in heart rate (HR) during tobacco chewing. Mean HR at baseline measured 73.0 ± 6.2 bpm. There was a rise in mean HR to 83.7 ± 9.1 bpm at 5 min during tobacco chewing and gradual reduction to baseline observed after 15 min followed by no significant change till 30 min. The normalized low-frequency power and LF/high-frequency (HF) power ratio were elevated after 5 min; however, normalized HF power was reduced after 5 min tobacco chewing. Conclusion: Gutkha is closely associated with traditional cardiovascular risk factors as detected by a transient enhancing sympathetic activity during tobacco chewing in the form of increased HRV parameters or an imbalance between sympathetic and parasympathetic neural activity among healthy young adults.

    What is the central question of this study? Neurocognitive functions can be enhanced by acute aerobic exercise, which could be associated with changes in serum brain-derived neurotrophic factor (BDNF) concentrations. We aimed to explore acute exercise-induced changes in BDNF concentrations, neuropsychological and neurophysiological performances when individuals with different levels of cardiorespiratory fitness performed a cognitive task. What is the main finding and its importance? Only young adults with higher cardiorespiratory fitness could attain switching cost and neurophysiological benefits via acute aerobic exercise. The mechanisms might be fitness dependent. Although acute aerobic exercise could enhance serum BDNF concentrations, changes in peripheral BDNF concentrations could not be the potential factor involved in the beneficial effects on neurocognitive performance. This study investigated the effects of acute aerobic exercise on neuropsychological and neurophysiological performances in young adults with different cardiorespiratory fitness levels when performing a task-switching protocol and explored the potential associations between acute aerobic exercise-induced changes in serum brain-derived neurotrophic factor (BDNF) concentrations and various neurocognitive outcomes. Sixty young adults were categorized into one control group (i.e. non-exercise-intervention; n = 20) and two exercise-intervention (EI) groups [i.e. higher (EIH , n = 20) and lower (EIL , n = 20) cardiorespiratory fitness] according to their maximal oxygen consumption. At baseline and after either an acute bout of 30 min of moderate-intensity aerobic exercise or a control period, the neuropsychological and neurophysiological performances and serum BDNF concentrations were measured when the participants performed a task-switching protocol involving executive control and greater demands on working memory.

    The "Acute Treatment of Migraine in Adults: The American Headache Society Evidence Assessment of Migraine Pharmacotherapies" provides levels of evidence for medication efficacy for acute treatment of migraine. The goal of this companion paper is to provide guidance on how to choose between evidence-based treatment options, and, based on the clinical characteristics of the patient and their migraine attacks, to provide guidance on designing an individualized strategy for managing migraine attacks. The acute pharmacological treatments described in the American Headache Society evidence assessment can be divided into those initially taken by the patient during the headache phase of the migraine attack, those taken by the patient later in the attack when initial treatments fail, and those administered intravenously or intramuscularly in urgent care settings. Medications taken initially by patients in the headache phase include nonspecific analgesics such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs), triptans, and dihydroergotamine (DHE). A stratified approach to treatment is advised, with the choice of medication based on the patient's treatment needs, taking into consideration the attack severity, presence of associated symptoms such as nausea and vomiting, and the degree of migraine-related disability. Individuals with migraine may find reassurance in having a "back-up plan" in the event of an initial acute treatment failure. For those individuals who had a partial response to the initial acute treatment, a second dose might be indicated. When the initial treatment does not provide meaningful and sustained benefits, a treatment from a different medication class is typically chosen. Depending upon the initial treatment used, this might include NSAIDs, triptans, or DHE. Opioids or acetaminophen in combination with codeine or tramadol can be considered as part of the "back-up plan," provided they are used infrequently. When all patient administered

    Feline gastrointestinal eosinophilic sclerosing fibroplasia was diagnosed in an 8-month-old Scottish fold that had a primary gastrointestinal mass involving the stomach, duodenum and mesenteric lymph nodes. Histopathologically, the most characteristic feature of this mass was granulation tissue with eosinophil infiltration and hyperplasia of sclerosing collagen fiber. Immunohistochemically, large spindle-shaped cells were positive for smooth muscle actin and vimentin. This case emphasizes the importance of feline gastrointestinal eosinophilic sclerosing fibroplasia as a differential diagnosis of gastrointestinal neoplastic lesions such as osteosarcoma and mast cell tumor in cats.

    Major basic protein, the primary constituent of eosinophil granules, regulates the alternative and classical pathways of complement. Major basic protein and other eosinophil granule cationic proteins, which are important in mediating tissue damage in allergic disease, regulate the alternative pathway by interfering with C3b interaction with factor B to assemble an alternative pathway C3 convertase. In the present study, eosinophil peroxidase, eosinophil cationic protein and eosinophil-derived neurotoxin, as well as major basic protein, were examined for capacity to regulate the classical pathway. Eosinophil peroxidase, eosinophil cationic protein and major basic protein inhibited formation of cell-bound classical pathway C3 convertase (EAC1,4b,2a), causing 50% inhibition of complement-mediated lysis at about 0.19, 0.75 and 0.5 micrograms/10(7) cellular intermediates, respectively. Eosinophil-derived neurotoxin had no activity on this pathway of complement. The eosinophil granule proteins were examined for activity on the formation of the membrane attack complex. Major basic protein and eosinophil cationic protein had no activity on terminal lysis. In contrast, eosinophil peroxidase inhibited lysis of EAC1,4b,2a,3b,5b, but had only minimal activity on later events in complement lysis. These polycations were then examined to determine the site(s) at which they regulated the early classical pathway. Eosinophil granule polycationic proteins: (1) reduced the Zmax at all time points but had only minimal effect on the Tmax during the formation of the classical pathway C3 convertase (EAC1,4b,2a); (2) inhibited formation of EAC1,4b,2a proportional to C4 but independent of C2 concentration; (3) inhibited fluid phase formation of C1,4b,2a, as reflected by a decrease in C1-induced consumption of C2 over time; and (4) inhibited C1 activity over time without a direct effect on either C4 or C2. These observations suggest that polycations regulate the early classical pathway by

    Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by symptoms of esophageal dysfunction and eosinophilic infiltration of the esophageal mucosa. The diagnosis requires esophageal biopsies demonstrating at least 15 eosinophils per high-powered field following a course of high-dose proton pump inhibitors. Management of EoE consists of the three Ds: drugs, dietary therapy, and esophageal dilation. In this review, we discuss the epidemiology, pathogenesis, diagnosis, and treatment of EoE to include the role of emerging therapies. PMID:26986655

The myenteric inflammatory infiltrate was eosinophil predominant with none of the immunological characteristics of lymphocytic ganglionitis. Neurones in the myenteric ganglia expressed the potent eosinophil chemoattractant interleukin 5. None responded to dietary exclusion but all three responded symptomatically to immunosuppression/anti-inflammatory treatments. Eosinophilic ganglionitis is associated with a pseudo-obstructive syndrome which is amenable to anti-inflammatory treatment.

    A 37-year-old male presented with severe oral and genital mucosal ulcers, lichenoid eruption and twenty-nail dystrophy. Systemic examination was normal, except for anemia. On investigations, he was found to have persistently elevated peripheral eosinophilia, absolute eosinophil count >5000/mm3, bone marrow showing increased eosinophilic precursors, and infiltration by atypical cells. The serum vitamin B12 levels were grossly elevated, and Philadelphia chromosome study was negative. Thus, a diagnosis of chronic eosinophilic leukemia was made. The patient showed excellent response to imatinib mesylate. We are reporting a rare type of leukemia presenting with predominantly cutaneous manifestations. PMID:27512192

    In contrast to FLT3 ITD mutations, in-frame deletions in the FLT3 gene have rarely been described in adult acute leukemia. We report two cases of AML with uncommon in-frame mutations in the juxtamembrane domain of the FLT3 gene: a 3-bp (c.1770_1774delCTACGinsGT; p.F590_V592delinsLF) deletion/insertion and a 12-bp (c.1780_1791delTTCAGAGAATAT; p.F594_Y597del) deletion. We verified by sequencing that the reading frame of the FLT3 gene was preserved and by cDNA analysis that the mRNA of the mutant allele was expressed in both cases. Given the recent development of FLT3 inhibitors, our findings may be of therapeutic value for AML patients harboring similar FLT3 mutations. PMID:25379410

    At times, total dissolved gas concentrations in the Columbia and Snake rivers have been elevated due to involuntary spill from high spring runoff and voluntary spill used as a method to pass juvenile salmonids over dams. The goal of this project was to determine if acute exposure to total dissolved gas supersaturation (TDGS) affects the reproductive performance of female chinook salmon late in their maturation. During this study, adult female spring chinook salmon were exposed to mean TDGS levels of 114.1 % to 125.5%. We ended exposures at first mortality, or at the appearance of impending death. Based on this criterion, exposures lasted from 10 to 68 h and were inversely related to TDGS. There was no effect of TDGS on pre-spawning mortality or fecundity when comparing treatment fish to experimental controls or the general hatchery population four to six weeks after exposures. Egg quality, based on egg weight and egg diameter, did not differ between treatment and control fish. Fertilization rate and survival to eyed-stage was high (>94%) for all groups. With the exception of Renibacterium salmoninarum (the causative agent of bacterial kidney disease; BKD), no viral or bacterial fish pathogens were isolated from experimental fish. The prevalence (about 45%) and severity of R. salmoninarum did not differ among the groups or the general hatchery population. We conclude that these acute exposures to moderate levels of gas-supersaturated water-perhaps similar to that experienced by immigrating adult salmon as they approach and pass a hydropower dam on the Columbia River-did not affect reproductive success of female chinook salmon late in their maturation. These results are most applicable to summer and fall chinook salmon, which migrate in the summer/fall and spawn shortly after reaching their natal streams.

    Background Post-acute care (PAC) is available for older adults who need additional services after hospitalization for acute cardiac events. With the aging population and an increase in the prevalence of cardiac disease, it is important to determine current PAC use for cardiac patients to assist health care workers to meet the needs of older cardiac patients. The purpose of this study was to determine the current PAC use and factors associated with PAC use for older adults following hospitalization for a cardiac event that includes coronary artery bypass graph (CABG) and valve surgeries, myocardial infarction (MI), percutaneous coronary intervention (PCI), and heart failure (HF). Methods and Results A cross-sectional design and the 2003 Medicare Part A database were used for this study. The sample (n=1,493,521) consisted of patients aged 65 years and older discharged after their first cardiac event. Multinomial logistic regression was used to examine factors associated with PAC use. Overall, PAC use was 55% for cardiac valve surgery, 50% for MI, 45% for HF, 44% for CABG, and 5% for PCI. Medical patients use more skilled nursing facility care and surgical patients use more home health care. Only 0.1–3.4% of the cardiac patients use intermediate rehabilitation facilities. Compared to those who do not use PAC, those who use home health care and skilled nursing facility care are older, female, have a longer hospital length of stay, and more comorbidity. Asians, Hispanics and Native Americans were less likely to use PAC after hospitalization for an MI or HF. Conclusions The current rate of PAC use indicates that almost half of non-disabled Medicare patients discharged from the hospital following a cardiac event use one of these services. Healthcare professionals can increase PAC use for Asians, Hispanics and Native Americans by including culturally targeted communication. Optimizing recovery for cardiac patients who use PAC may require focused cardiac rehabilitation

    Background Lower respiratory tract infections (LRTI) are a common reason for consulting general practitioners (GPs). In most cases the aetiology is unknown, yet most result in an antibiotic prescription. The aetiology of LRTI was investigated in a prospective controlled study. Methods Eighty adults presenting to GPs with acute LRTI were recruited together with 49 controls over 12 months. Throat swabs, nasal aspirates (patients and controls), and sputum (patients) were obtained and polymerase chain reaction (PCR) and reverse transcriptase polymerase chain reaction (RT‐PCR) assays were used to detect Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumophila, influenza viruses (AH1, AH3 and B), parainfluenza viruses 1–3, coronaviruses, respiratory syncytial virus, adenoviruses, rhinoviruses, and enteroviruses. Standard sputum bacteriology was also performed. Outcome was recorded at a follow up visit. Results Potential pathogens were identified in 55 patients with LRTI (69%) and seven controls (14%; p<0.0001). The identification rate was 63% (viruses) and 26% (bacteria) for patients and 12% (p<0.0001) and 6% (p = 0.013), respectively, for controls. The most common organisms identified in the patients were rhinoviruses (33%), influenza viruses (24%), and Streptococcus pneumoniae (19%) compared with 2% (p<0.001), 6% (p = 0.013), and 4% (p = 0.034), respectively, in controls. Multiple pathogens were identified in 18 of the 80 LRTI patients (22.5%) and in two of the 49 controls (4%; p = 0.011). Atypical organisms were rarely identified. Cases with bacterial aetiology were clinically indistinguishable from those with viral aetiology. Conclusion Patients presenting to GPs with acute adult LRTI predominantly have a viral illness which is most commonly caused by rhinoviruses and influenza viruses. PMID:16227331

    The negative feedback mechanism through which 17β-estradiol (E2) acts to suppress the activity of the GnRH neurons remains unclear. Using inducible and cell-specific genetic mouse models, we examined the estrogen receptor (ER) isoforms expressed by neurons that mediate acute estrogen negative feedback. Adult female mutant mice in which ERα was deleted from all neurons in the neonatal period failed to exhibit estrous cycles or negative feedback. Adult mutant female mice with neonatal neuronal ERβ deletion exhibited normal estrous cycles, but a failure of E2 to suppress LH secretion was seen in ovariectomized mice. Mutant mice with a GnRH neuron-selective deletion of ERβ exhibited normal cycles and negative feedback, suggesting no critical role for ERβ in GnRH neurons in acute negative feedback. To examine the adult roles of neurons expressing ERα, an inducible tamoxifen-based Cre-LoxP approach was used to ablate ERα from neurons that express calmodulin kinase IIα in adults. This resulted in mice with no estrous cycles, a normal increase in LH after ovariectomy, but an inability of E2 to suppress LH secretion. Finally, acute administration of ERα- and ERβ-selective agonists to adult ovariectomized wild-type mice revealed that activation of ERα suppressed LH secretion, whereas ERβ agonists had no effect. This study highlights the differences in adult reproductive phenotypes that result from neonatal vs adult ablation of ERα in the brain. Together, these experiments expand previous global knockout studies by demonstrating that neurons expressing ERα are essential and probably sufficient for the acute estrogen negative feedback mechanism in female mice.

    Background Deep eosinophilic granulomatous abscesses, as distinguished from eosinophilic subcutaneous abscesses, are rare. Most reports are from the Far-East and India where the most commonly attributed cause is Toxocara. Sulaimaniyah in Northeastern Iraq has experienced an outbreak of eosinophilic granulomatous liver and gastrointestinal (GI) abscesses beginning in 2009. The purpose of this study was to determine the etiology and guide treatment. Methods The study was an ongoing investigation of patients having a histopathologic diagnosis of eosinophilic granulomatous abdominal abscesses in Sulaimaniyah hospitals from May 2009 to August 2012. Tissues were examined for organisms, and Enzyme Linked Immunoabsorbent Assays (ELISA) were performed for serum antibodies to Fasciola hepatica, Toxocara, and Echinococcus granulosus. Results Fourteen patients had granulomatous inflammation surrounding a central necrotizing eosinophilic exudate identified in surgical pathology specimens from abdominal surgeries. Two children and four adults had abscesses that formed GI masses. These patients included a 39 year old male with oropharyngeal and transverse colon disease, and a 48 year old male with liver and GI abscesses. All sites demonstrated a Zygomycete fungus surrounded by eosinophilic Splendori-Hoeppli material consistent with basidiobolomycosis. Five of the six patients with fungal disease were treated by surgery and 4 to 7 months of itraconozol. One child died of intestinal perforation while receiving IV amphotericin B; two adults required additional surgery for recurrent GI obstruction. Eight patients had isolated liver abscesses with no organisms identified by histopathology: ELISA results for F. hepatica were positive for five, borderline for one, and negative for two patients. These eight patients were treated for fascioliasis by surgical resection of localized abscesses and albendazol. One patient serologically positive for F. Hepatica was found to have a common duct
