    Cardiomyopathies are a heterogenous group of heart ailments. Some of them are primary myocardial diseases and are classified as dilated, hypertrophic, restrictive and arryhithmogenic. Dilated cardiomyopathies (DCs) are the most common. Sometimes it is possible to identify an etiologic agent, in that case we talk about a specific dilated cardiomyopathy. Here in, we review one of these specific DCs, the so called Chronic Chagasic Cardiopathy (CCC) from the point of view of our personal experience at the Instituto Nacional de Cardiología "Ignacio Chávez". Chagas' disease is present in Mexico, therefore CCC is also present. We estimate that 5,000 people, suffer CCC with severe symptoms. In Mexico, Chagas' disease occurs below the Tropic of Cancer and between 2,000-2,500 m above sea level, in this area there is a real risk for vectorial infection, mainly in rural villages. Clinical diagnosis should be supported by epidemiological and seroepidemiological confirmatory data. There is not appropriate therapy yet for this condition.

    A progressive destruction of the myocardium occurs in ∼30% of Trypanosoma cruzi-infected individuals, causing chronic chagasic cardiomyopathy, a disease so far without effective treatment. Syngeneic bone marrow cell transplantation has been shown to cause repair and improvement of heart function in a number of studies in patients and animal models of ischemic cardiopathy. The effects of bone marrow transplant in a mouse model of chronic chagasic cardiomyopathy, in the presence of the disease ...

    Full Text Available In this longitudinal study 5,710 people were included. The inclusion criteria were two positive serological results for Trypanosoma cruzi infection, 15 and 50 years old and no other demostrable diesease at the time of study. In the five year follow up 1,117 patients were lost. The follow up involved yearly evaluation of serology, clinical examination, X-ray of torax, and ECG, for 4,593 patients and 263 were contacted at home because they did not assist for their clinical consultant. Time average of follow up was 5.3 years. Eighty nine (1.5% of the 4,593 patients died during the follow-up period, 63 (71% by cardiac insufiency (CI and 26 (29% by severe ventricular arrithmias. Diagnosis of cardiomegaly was present in all the patients with diagnosis of CI and in 15 (5% of the patients with diagnosis of arrithmias.The ECG alterations of these pacients show 61 right bundle brunch block (RBBB, associated or not with left anterior hemiblock (LAHB, 47 pathological Q wave and 70 primary repolarization alterations; 61 had polyfocal ventricular arrithmia. The death rate was similar in the sexes and was more frequent between 40 and 50 years of age. Information on 1,380 recuperated patients shows that 15 died with no previous symptoms and without medical assistance and were interpretate as sudden death. The latest ECG in three follow-up of these pacients indicates (before death that only one had normal study and 14 presented 12 RBBB; 9 LAHB; 7 isolated ventricular arrithmia; 10 repolariz alterations; 2 patological Q wave, 10 patients of them with RBBB and repolariz alterations. In all the cases we had people between 35 and 43 years old, 9 men and 6 women. This study shows that in Chagas disease is possible to differenciate two risk groups. A low risk death group that have normal ECG and clinical evaluation during the follow up, and a high risk group associate ECG with RBBB and primary alterations of repolarization and/or inactivation zones with not anual clinical evaluation.

    Full Text Available The aim of the present study was to assess the effects of an anticholinesterase agent, pyridostigmine bromide (Pyrido, on experimental chronic Chagas heart disease in mice. To this end, male C57BL/6J mice noninfected (control:Con or chronically infected (5 months with Trypanosoma cruzi (chagasic:Chg were treated or not (NT with Pyrido for one month. At the end of this period, electrocardiogram (ECG; cardiac autonomic function; heart histopathology; serum cytokines; and the presence of blood and tissue parasites by means of immunohistochemistry and PCR were assessed. In NT-Chg mice, significant changes in the electrocardiographic, autonomic, and cardiac histopathological profiles were observed confirming a chronic inflammatory response. Treatment with Pyrido in Chagasic mice caused a significant reduction of myocardial inflammatory infiltration, fibrosis, and hypertrophy, which was accompanied by a decrease in serum levels of IFNγ with no change in IL-10 levels, suggesting a shift of immune response toward an anti-inflammatory profile. Lower nondifferent numbers of parasite DNA copies were observed in both treated and nontreated chagasic mice. In conclusion, our findings confirm the marked neuroimmunomodulatory role played by the parasympathetic autonomic nervous system in the evolution of the inflammatory-immune response to T. cruzi during experimental chronic Chagas heart disease in mice.

    In this study the slopes of the QRS complex are evaluated for determination of the degree of myocardial damage in chronic chagasic patients. Previous studies have demonstrated the ability of the slope indices to reflect alterations in the conduction velocity of the cardiac impulse. Results obtained in the present study show that chronic chagasic patients have significantly flatter QRS slopes as compared to healthy subjects. Not only that but the extent of slope lessening turns out to be proportional to the degree of myocardial damage caused by the disease. Additionally, when incorporating the slope indices into a classification analysis together with other indices indicative of the presence of ventricular late potentials obtained from high resolution electrocardiography, results show that the percentages of correct classification increase up to 62.5%, which means eight points above the percentages obtained prior to incorporation of the slope indices. It can be concluded that QRS slopes have great potential for assessing the degree of severity associated with Chagas' disease.

    Full Text Available On the American continent, almost 15 million people are affected by Chagas disease, resulting in important economic and social damages. Dogs are considered to be an excellent experimental model to study Chagas' disease; as a result, in this research, the characterization of cardiovascular abnormalities was performed in dogs experimentally infected with Trypanosoma cruzi (the Colombian strain that were at chronic stage. Thirteen adult female dogs were evaluated by electrocardiographic, echocardiographic, hematological and biochemical analyses in the chronic phase. For the electrocardiographic studies, respiratory sinus arrhythmia was the predominant rhythm during the entire research period (49.55% to 67%, with a low prevalence of right bundle branch block (0-13% and first-degree atrioventricular block (0-14%. The spectral Doppler echocardio-graphy showed E and A mitral wave reversal (0.71±0.17, confirming the diastolic dysfunction present in all dogs. An increase in the enzymes activities was detected in the serum analysis, indicating myocardial injury by the infection. Six dogs died during the follow-up. In this way, the clinical characterization of experimentally infected dogs, as described here, increases the knowledge and allows for recognition of the behavioural modifications present in Chagas' disease in affected dogs.No continente Americano, aproximadamente 15 milhões de pessoas são afetadas pela doença de Chagas, ocasionando importantes danos econômicos e sociais.

    Full Text Available As patients with chronic Chagas disease exhibit morphological and functional changes of the stomach (hypomotility and hypochlorhydria, malnutrition, immunological deficiency and high prevalence of peptic disease associated to Helicobater pylori infection, the purpose of this study was to evaluate if the prevalence of H. pylori infection in chronic chagasic is higher than in non-chagasic individuals in the urban and rural population from Uberlândia, MG, Brazil. Serological determination of IgG antibodies to H. pylori was performed using a second-generation ELISA. Thus, 598 people were evaluated: 128 chagasic (CG, 222 non-chagasic living in urban area (U-NCG and 248 non-chagasic living in rural area (R-NCG. Regarding the age range from 21 to 50 years, the prevalence of H. pylori infection in the CG (85.1% was significantly higher than in the U-NCG (56.3%, p < 0.01 and the R-NCG (67.4%, p < 0.05. In the patients over 50 years, the prevalence in the CG (86.4% was similar to the U-NCG (78.8% and R-NCG (86.1%. Similar results were also found between the U-NCG and R-NCG for all age ranges, with prevalence rates of 29.1% and 35.3% for the age range from 5 to 13 years, and 47.2% and 40% for that from 14 to 20 years, respectively. We conclude that chagasic patients showed a higher seroprevalence of H. pylori infection than non-chagasic individuals, in the age range from 21 to 50 years, and that the prevalence of this infection was similar in the studied urban and rural non-chagasic population.

    Background Cardiovascular diseases are the major cause of death in the world. Current treatments have not been able to reverse this scenario, creating the need for the development of new therapies. Cell therapies have emerged as an alternative for cardiac diseases of distinct causes in experimental animal studies and more recently in clinical trials. Method/Design We have designed clinical trials to test for the efficacy of autologous bone marrow derived mononuclear cell therapies in four different cardiopathies: acute and chronic ischemic heart disease, and Chagasic and dilated cardiomyopathy. All trials are multicenter, randomized, double-blind and placebo controlled. In each trial 300 patients will be enrolled and receive optimized therapy for their specific condition. Additionally, half of the patients will receive the autologous bone marrow cells while the other half will receive placebo (saline with 5% autologous serum). For each trial there are specific inclusion and exclusion criteria and the method for cell delivery is intramyocardial for the chronic ischemic heart disease and intracoronary for all others. Primary endpoint for all studies will be the difference in ejection fraction (determined by Simpson's rule) six and twelve months after intervention in relation to the basal ejection fraction. The main hypothesis of this study is that the patients who receive the autologous bone-marrow stem cell implant will have after a 6 month follow-up a mean increase of 5% in absolute left ventricular ejection fraction in comparison with the control group. Discussion Many phase I clinical trials using cell therapy for cardiac diseases have already been performed. The few randomized studies have yielded conflicting results, rendering necessary larger well controlled trials to test for efficacy of cell therapies in cardiopathies.

    Full Text Available Thirty-five Trypanosoma cruzi strains were isolated from chronic chagasic patients, triatomines and opossums from different municipalities of the State of Rio Grande do Sul. Parasites were characterized by means of mice infectivity, enzyme electrophoresis and randomly amplified polymorphic DNA (RAPD analysis. Twenty-nine strains were isolated from chagasic patients, 4 from triatomines (2 from Triatoma infestans and 2 from Panstrongylus megistus and 2 from opossums Didelphis albiventris. Thirty-three T. cruzi strains were of low and 2 strains of high virulence in mice. Both virulent strains were isolated from P. megistus. Isoenzyme analysis of the strains showed 3 different zymodemes. Eleven strains isolated from chagasic patients and 2 from D. albiventris were Z2. Eighteen strains from patients and 2 from T. infestans were ZB and 2 T. cruzi strains isolated from P. megistus were Z1. RAPD profiles obtained with 4 random primers showed a high genetic heterogeneity of the T. cruzi strains. Zymodeme 2 and ZB strains were the more polymorphic. A band sharing analysis of the RAPD profiles of Z2 and ZB strains using 3 primers, showed a very low percentage of shared bands, 20% among 13 ZB strains and 14% among 13 Z2 strains. According to the isoenzyme results, 3 T. cruzi populations were present in State of Rio Grande do Sul. Zymodeme 2 and ZB strains were found infecting man (domiciliar transmission cycle whereas Z1 strains were found infecting the sylvatic vector P. megistus

    an extensive microarray analysis of hearts from a mouse model of this disease and identified significant alterations in expression of approximately 12% of the sampled genes. Extensive up-regulations were associated with immune-inflammatory responses (chemokines, adhesion molecules, cathepsins, and major...... histocompatibility complex molecules) and fibrosis (extracellular matrix components, lysyl oxidase, and tissue inhibitor of metalloproteinase 1). Our results indicate potentially relevant factors involved in the pathogenesis of the disease that may provide new therapeutic targets in chronic Chagas disease....

    Vitamin D is an important modulator of the immune response. It acts over several immune cell types where the Vitamin D receptor (VDR) is expressed. Due to the high relevance of this signaling pathway, several studies have investigated the possible influence of genes involved in the metabolism of Vitamin D and its receptor in different human diseases. Here, we analyzed whether four single-nucleotide polymorphisms of the VDR gene (rs731236, rs7975232, rs1544410 and rs2228570) are involved in the susceptibility to infection by Trypanosoma cruzi and/or to chronic Chagas cardiomyopathy (CCC) in a Colombian endemic population for this parasite. Our results showed that the rs2228570*A allele is associated with CCC development (P = 4.46E-03, OR = 1.51). In summary, the data presented in this report suggest that variation within the VDR gene may affect the immune response against T. cruzi, increasing the probability of cardiac complications in infected individuals.

    Full Text Available To compare parasitism and inflammatory process in esophagus and colon from chronic chagasic patients, immunohistochemistry was carried out to research for T. cruzi and to evaluate the inflammatory infiltrate in the muscular and myenteric plexus in 39 esophagi (20 with and 19 without megaesophagus and 50 colons (25 with and 25 without megacolon. The frequency of T. cruzi in megaesophagus was 20%, and in megacolon it was 4%. No amastigotes were found in organs without mega; considering the total of esophagi (with and without mega, the frequency of T. cruzi would be 10% and 2% in the colon. Myositis and ganglionitis were more frequent and intense in organs with mega compared to those without mega, and in esophagus compared to colon. Qualitatively, inflammatory infiltration in esophagus and colon, with or without mega, was similar, consisting predominantly of T lymphocytes (CD3+, scarce macrophages (CD68+, and rare B lymphocytes (CD20+.

Notou-se flebite crônica inespecífica, focal e discreta, em cinco chagásicos (bilateral em três pacientes e dois controles; havia infiltração mononuclear discreta do interstício funicular em treze chagásicos e cinco controles. A análise estatística dos resultados (chi2 não revelou diferenças significativas. Conclui-se que o ambiente hormonal devido à testosterona não parece favorecer a infecção da parede dos vasos gonadais por Trypanosoma cruzi, embora, segundo a literatura, o referido hormônio pareça ter ações imunodepressoras.The occurrence of Trypanosoma cruzi intracellular clusters and phlebitis was searched for on pampiniform plexus vein walls of chronic chagasic patients.

    Human and experimental Chagas' disease causes peripheral nervous system damage involving neuromuscular transmission alterations at the neuromuscular junction. Additionally, autoantibodies directed to peripheral nerves and sarcolemmal proteins of skeletal muscle have been described. In this work, we analyse the ability of serum immunoglobulin factors associated with human chagasic infection to bind the affinity-purified nicotinic acetylcholine receptor (nAChR) from electric organs of Discopyge tschudii and to identify the receptor subunits involved in the interaction. The frequency of serum anti-nAChR reactivity assayed by dot-blot was higher in seropositive chagasic patients than in uninfected subjects. Purified IgG obtained from chagasic patients immunoprecipitated a significantly higher fraction of the solubilized nAChR than normal IgG. Furthermore, immunoblotting assays indicated that α and β are the main subunits involved in the interaction. Chagasic IgG was able to inhibit the binding of α-bungarotoxin to the receptor in a concentration-dependent manner, confirming the contribution of the α-subunit in the autoantibody-receptor interaction. The presence of anti-nAChR antibodies was detected in 73% of chagasic patients with impairment of neuromuscular transmission in conventional electromyographical studies, indicating a strong association between seropositive reactivity against nAChR and electromyographical abnormalities in chagasic patients. The chronic binding of these autoantibodies to the nAChR could induce a decrease in the population of functional nAChRs at the neuromuscular junction and consequently contribute to the electrophysiological neuromuscular alterations described in the course of chronic Chagas' disease.

Apresentamos, no presente trabalho, uma hipótese alternativa. Acreditamos que o desenvolvimento da miocardite está relacionado à necrose celular focal progressiva e acumulativa, associada à fibrose intersticial reparativa e reativa e hipertrofia miocitária circunjacente. Esses processos seriam iniciados e perpetuados por fatores autoimunes e alterações na microcirculação do miocárdio. Esse mecanismo fisiopatogênico teria possíveis implicações em futuras estratégias terapêuticas no tratamento do paciente chagásico crônico visando otimizar o tratamento médico e auspiciosamente melhorar o prognóstico.The pathogenesis of chronic chagasic myocarditis remains incompletely understood. Several hypotheses have been proposed: (1 direct tissue destruction by Trypanosoma cruzi; (2 neurogenic theory; (3 anti-heart immune reactions; and (4 microvascular disease. We present herein a dynamic alternative hypothesis. We believe that the development of myocarditis is related to progressive and additive focal cellular necrosis, and associated reactive and reparative myocardial fibrosis and surrounding myocytes hypertrophy. These processes may be initiated and perpetuated by autoimmune factors and alterations in the myocardial microcirculation. This could imply future therapeutic strategies in the management of chronic chagasic patients to optimize the medical treatment and hopefully improve the prognosis.

    Full Text Available Involvement of the hollow organs of the digestive apparatus can occur in patients in the chronic phase of Chagas' disease. The basic mechanism is destruction of neurons of the enteric nervous system. Whereas megaesophagus and megacolon are the most notable and most extensively studied expressions of the digestive form of Chagas' disease, involvement of the small intestine (Chagasic enteropathy is less frequent and less known than involvement of the two above mentioned entities. Chagasic enteropathy can be responsible for important clinical and laboratory manifestations resembling those of dyspeptic syndrome, intestinal pseudo-obstruction and bacterial overgrowth in the small intestine. Chagasic enteropathy also involves peculiar functional changes, especially those related to motor activity of the organ and to intestinal absorption of carbohydrates. In practice, the diagnosis is based on radiographic documentation of dilation of visceral segments. Treatment consists of clinical control of the above syndromes and, eventually, appropriate surgical operations.O comprometimento dos órgãos ocos do aparelho digestivo pode ocorrer nos portadores da fase crônica da doença de Chagas. O mecanismo básico é a destruição dos neurônios do sistema nervoso entérico.

A enteropatia chagásica pode ser responsável por importantes manifestações clínicas e laboratoriais que se assemelham às das síndromes dispéptica, de pseudo-obstrução intestinal e de supercrescimento bacteriano no intestino delgado.

    ventricular systolic and diastolic functions is still controversial and little explored in chronic Chagas' disease. OBJECTIVE: To evaluate the extent to which cardiac autonomic and mechanical ventricular functions are altered and whether they are associated in asymptomatic chagasic cardiomyopathy. METHODS: A total of 13 patients with asymptomatic chagasic cardiomyopathy and 15 normal subjects (control group were evaluated and the autonomic modulation of heart rate variability for five minutes, in the temporal and spectral domains, in the supine and orthostatic positions, as well as ventricular function based on morphological-functional variables obtained by Doppler echocardiography were correlated. Statistical analysis used the Mann-Whitney test and Spearman's correlation. RESULTS: In both positions, the temporal index (p = 0.0004 to 0.01 and total (p = 0.0007-0.005 and absolute spectral areas, of low and high frequencies (p = 0.0001 to 0.002, were lower in the chagasic group. The vagal-sympathetic balance was similar in both positions (p = 0.43 to 0.89. The echocardiographic variables did not differ between groups (p = 0.13 to 0.82, except the left ventricular end-systolic diameter, which was larger (p = 0.04 and correlated directly with reduced rates of global (p = 0.01 to 0.04 and parasympathetic (p = 0.002 to 0.01 autonomic modulation in patients with Chagas disease in the orthostatic position. CONCLUSION: The sympathetic and parasympathetic depressions with preserved balance were associated with only one ventricular dysfunction indicator. This suggests that cardiac autonomic dysfunction may precede and be independently more severe than ventricular dysfunction, with no causal association between both disorders in chronic chagasic cardiomyopathy.

    Disordered gut motor activity is a feature of patients with Chagas' disease: colonic involvement leads to the development of megacolon and symptoms of constipation. Interstitial cells of Cajal are thought to modulate gut motility. The aim of this study was to test the hypothesis that there is an abnormality of the density of distribution of interstitial cells of Cajal in Chagasic megacolon. Interstitial cells of Cajal were identified by immunohistochemistry using an anti-c-kit antibody. Six patients with Chagasic megacolon were compared with normal controls. The density of distribution of interstitial cells of Cajal was assessed in the longitudinal and circular muscle layers, and in the intermuscular plane of the Chagasic and normal colon. Statistical analysis was performed using Fisher's exact test. The interstitial cells of Cajal density in Chagasic megacolon was much reduced in comparison to normal colonic tissue in the longitudinal muscle layer (P=0.0084), intermuscular plane (P<0.0001), and circular muscle layer (P=0.0051). The lack of interstitial cells of Cajal may play a role in the pathophysiology of the disease, leading to the development of megacolon and symptoms of constipation.

    Ovarian hormone depletion in ovariectomized experimental animals is a useful model with which to study the physiopathological consequences of menopause in women. It has been suggested that menopause is a risk factor for the induction of several cardiovascular disorders. In the present study we analyzed the effects of ovarian hormone depletion by ovariectomy (OVX) in a model of oxidative stress and cardiopathy induced by adriamycin (AD). To evaluate these effects, we measured parameters related to cardiac damage (creatinine kinase, lactate dehydrogenase, aspartate aminotransferase and alanine aminotransferase) and oxidative stress (malondialdehyde, catalase, superoxide dismutase, glutathione peroxidase, reduced glutathione, nitric oxide and carbonyl proteins) in cardiac tissue and erythrocytes. OVX was found to alter all markers of oxidative stress and cell damage in cardiac tissue. Similarly, the OVX-derived loss of ovarian hormones enhanced cardiac damage and oxidative stress induced by AD. Our results suggest that antioxidant status in cardiac tissue and erythrocytes is seriously compromised by OVX during the cardiomyopathy induced by AD in experimental animals. In conclusion, the absence of hormones caused by OVX or menopause may induce or accelerate pre-existing cardiovascular dysfunctions.

    positive. Specific treatment for Trypanosoma cruzi was administered, consisting of benznidazole, but the course of treatment was not completed because the patient died due to cardiopathic complications. The necropsy showed the usual stigmas of chronic Chagas cardiopathy, such as fibrosing myocarditis and a decreased number of neurons in the digestive system. There were no amastigote forms of Trypanosoma cruzi in any of the tissue samples studied. Therefore, reactivation of Chagas disease was not demonstrated but, rather, the natural evolution of chronic Chagas cardiopathy was demonstrated.

    Full Text Available Diagnosis, prognosis and evaluation of death risk in Chagas cardiomyopathy still constitute a challenge due to the diversity of manifestations, which determine the importance of using echocardiography, tissue Doppler and biomarkers. To evaluate, within a systematic review, clinical and echocardiographic profiles of patients with chronic chagasic cardiomyopathy, which may be related to worse prognosis and major mortality risk. To perform the systematic review, we used Medline (via PubMed, LILACS and SciELO databases to identify 82 articles published from 1991 to 2012, with the following descriptors: echocardiography, mortality and Chagas disease. We selected 31 original articles, involving diagnostic and prognostic methods. The importance of Chagas disease has increased due to its emergence in Europe and United States, but most evidence came from Brazil. Among the predictors of worse prognosis and higher mortality risk are morphological and functional alterations in the left and right ventricles, evaluated by conventional echocardiography and tissue Doppler, as well as the increase in brain natriuretic peptide and troponin I concentrations. Recently, the evaluations of dyssynchrony, dysautonomia, as well as strain, strain rate and myocardial twisting were added to the diagnostic arsenal for the early differentiation of Chagas cardiomyopathy. Developments in imaging and biochemical diagnostic procedures have enabled more detailed cardiac evaluations, which demonstrate the early involvement of both ventricles, allowing a more accurate assessment of the mortality risk in Chagas disease.

    Full Text Available OBJECTIVE: To study electrophysiological characteristics that enable the identification and ablation of sites of chagasic tachycardia. METHODS: Thirty-one patients with chronic Chagas' heart disease and sustained ventricular tachycardia (SVT underwent electrophysiological study to map and ablate that arrhythmia. Fifteen patients had hemodinamically stable SVT reproducible by programmed ventricular stimulation, 9 men and 6 women with ages ranging from 37 to 67 years and ejection fraction varying from 0.17 to 0.64. Endocardial mapping was performed during SVT in all patients. Radiofrequency (RF current was applied to sites of presystolic activity of at least 30 ms. Entrainment was used to identify reentrant circuits. In both successful and unsuccessful sites of RF current application, electrogram and entrainment were analyzed. RESULTS: Entrainment was obtained during all mapped SVT. In 70.5% of the sites we observed concealed entrainment and ventricular tachycardia termination in the first 15 seconds of RF current application. In the unsuccessful sites, significantly earlier electrical activity was seen than in the successful ones. Concealed entrainment was significantly associated with ventricular tachycardia termination. Bystander areas were not observed. CONCLUSION: The reentrant mechanism was responsible for the genesis of all tachycardias. In 70.5% of the studied sites, the endocardial participation of the slow conducting zone of reentrant circuits was shown. Concealed entrainment was the main electrophysiological parameter associated with successful RF current application. There was no electrophysiological evidence of bystander regions in the mapped circuits of SVT.

    Full Text Available Human Chagas' disease, caused by the protozoan Trypanosoma cruzi, is associated with pathological processes whose mechanisms are not known. To address this question, T cell lines were developed from chronic chagasic patients peripheral blood mononuclear cells (PBMC and cloned. These T cell clones (TCC were analyzed phenotypically with monoclonal antibodies by the use of a fluorescence microscope. The surface phenotype of the TCC from the asymptomatic patient were predominantly CD4 positive (86%. On the contrary, the surface phenotype CD8 was predominant in the TCC from the patients suffering from cardiomegaly with right bundle branch block (83%, bradycardia with megacolon (75 % and bradycardia (75%. Future studies will be developed in order to identify the antigens eliciting these T cell subpopulations.

    Full Text Available In México the first human chronic chagasic case was recognized in 1940. In spite of an increasing number of cases detected since that time, Chagas disease in México has been poorly documented. In the present work we studied 617 volunteers subjects living in high and low endemic regions of Trypanosoma cruzi infection with seroprevalence of 22% and 4% respectively. Hemoculture performed in those seropositive subjects failed to demonstrate circulating parasites, however polymerase chain reaction identified up to 60% of them as positives. A higher level of anti-T. cruzi antibodies was observed in seropositive residents in high endemic region, in spite of similar parasite persistence (p < 0.05. On standard 12 leads electrocardiogram (ECG 20% to 22% seropositive individuals from either region showed right bundle branch block or ventricular extrasystoles which were more prevalent in seropositive than in seronegative individuals (p < 0.05. In conclusion, the frequency or type of ECG abnormality was influenced by serologic status but not by endemicity or parasite persistence. Furthermore, Mexican indeterminate patients have a similar ECG pattern to those reported in South America.

    We developed a novel murine model of long-term infection with Trypanosoma cruzi with the aim to elucidate the pathogenesis of megacolon and the associated adaptive and neuromuscular intestinal disorders. Our intent was to produce a chronic stage of the disease since the early treatment should avoid 100% mortality of untreated animals at acute phase. Treatment allowed animals to be kept infected and alive in order to develop the chronic phase of infection with low parasitism as in human disease. A group of Swiss mice was infected with the Y strain of T. cruzi. At the 11th day after infection, a sub-group was euthanized (acute-phase group) and another sub-group was treated with benznidazole and euthanized 15 months after infection (chronic-phase group). Whole colon samples were harvested and used for studying the histopathology of the intestinal smooth muscle and the plasticity of the enteric nerves. In the acute phase, all animals presented inflammatory lesions associated with intense and diffuse parasitism of the muscular and submucosa layers, which were enlarged when compared with the controls. The occurrence of intense degenerative inflammatory changes and increased reticular fibers suggests inflammatory-induced necrosis of muscle cells. In the chronic phase, parasitism was insignificant; however, the architecture of Aüerbach plexuses was focally affected in the inflamed areas, and a significant decrease in the number of neurons and in the density of intramuscular nerve bundles was detected. Other changes observed included increased thickness of the colon wall, diffuse muscle cell hypertrophy, and increased collagen deposition, indicating early fibrosis in the damaged areas. Mast cell count significantly increased in the muscular layers. We propose a model for studying the long-term (15 months) pathogenesis of Chagasic megacolon in mice that mimics the human disease, which persists for several years and has not been fully elucidated.

    AIM: To analyze the risk of cardiovascular complications in patients with indication for surgical treatment of Chagasic esophageal achalasia and to correlate the surgical risks with the degree of esophageal dilation,thereby proposing a risk scale index.METHODS: One hundred and twenty-four patients with Chagasic esophageal achalasia, who received surgical treatment at the Hospital das Clinicas of the Federal patients were mostly related to the postoperative complications due to the cardiovascular system. All the patients were submitted to: (1) clinical history to define the cardiac functional class (New York Heart Association);(2) conventional 12-lead electrocardiogram at rest; and (3) contrast imaging of the esophagus to determine esophageal dilatation according to Rezende's classification of Chagasic megaesophagus.RESULTS: An assessment of the functional classification (FC) of heart failure during the preoperative period determined that 67 patients (54.03%) were assigned functional class Ⅰ (FC Ⅰ), 46 patients (37.09%) were assigned functional class Ⅱ (FC Ⅱ), and 11 patients (8.87%) were assigned functional class Ⅲ (FC Ⅲ). None of the patients were assigned to functional class Ⅳ (FC Ⅳ). There was a positive correlation between the functional class and the postoperative complications (FC ⅠxFC Ⅱ: P<0.001; FC ⅠxFC Ⅲ: P<0.001). The ECG was normal in 44 patients (35.48%) and presented abnormalities in 80 patients (64.52%).

    Full Text Available CONTEXT: The treatment of Chagas' disease colopathy is limited to clinical management in the initial of the process, and for patients for whom surgery is not indicated or is not possible, anti-constipation diets are used, along with judicious administration of laxatives and enemas. OBJECTIVE: To evaluate over time the effects of physical-therapy interventions combined with daily ingestion of a laxative fruit drink in the treatment of chagasic megacolon. METHOD: In a quantitative, prospective, and comparative study, 12 patients of both sexes and with a mean age of 67 ± 12 years were clinically evaluated to receive 12 sessions of physical therapy twice a week, along with fruit drink, and were evaluated for intestinal constipation before and after treatment. RESULTS: A significant difference (P0.05. CONCLUSION: The proposed protocol is easy to implement, safe, non-invasive, and low-cost, with the potential to be deployed in health care by providing benefits independent of gender, age, or whether the participant has undergone surgery, improving the condition of patients with chagasic megacolon.

    Full Text Available There is a clear association between chagasic megaesophagus and the esophageal cancer. On the other hand, the association between chagasic megacolon and intestinal neoplasm is uncommon. There are only a few cases described in literature. We selected two cases of colorectal adenocarcinoma associated with adenoma from 2000 to 2011, which are added to the four patients already described by this group. The mean age of the patients, was 68.5 years. Both had been submitted to surgical resection of the neoplasm. Survival rates ranged and were directly related to tumor staging at the time of diagnosis. In this context, we report our case series and reviwed the corresponding literature, especially the clinical and epidemiological aspects of this rare association.Há uma clara associação entre megaesôfago por doença de Chagas e o câncer esofágico.

    The Coronary Arterial Illness (EAC) is the first cause of death of those Mexicans. Among their numerous risk factors it highlights the age with more bias starting from the 45 years. The objective of this investigation was to determine the prevailing of ischemic cardiopathy (Cl) and heart attack to the myocardium (IAM) in fellows smaller than 40 years and to identify risk factors. The study of myocardial perfusion (EPM) it is a non invasive study and of great sensibility and specificity that it allows to detect obstructive coronary lesions. The used method was retrospective-traverse Study in 125 patients smaller than 40 years. Files of patients to who EPM had been practiced with Technetium 99m-SESTAMlBI, protocol of one day, were revised, where its were analyzed the short and long axis (vertical and horizontal). General data, somatometry, emotional profile analysis, lipids and glucose profiles were gathered. Results. The population conformed it 53% women and 47% men with average of 31.9 year-old age of corporal mass index (IMC) 25.1 kg/cm2. 46% of abnormal studies was obtained, of which 35% was compatible with ischemic cardiopathy (Cl) and 11% with heart attack to the myocardium (IAM). The characteristics of these were: age 31.6±6 Vs 32.6±5.9 years; IMC 25.4±7.0 Vs 24.4±3.34 kg/cm2; stature 161.6±9.8 Vs 165.5±9.7cm; TAS 139.1±29.2 Vs. 115±13.4 mm Hg, TAD 84.5±17.4 Vs. 75±9.4 mm Hg; civil state married 65.5% (p=0.005) Vs single 57%; bigger depression 32% Vs anxiety 28%, in the group of patients with Cl and IAM, respectively. In the IAM population it was found an additional IRC 21% (p=0.030), HAS 21% (p=0.025) and drug addiction 21% (p=0.002). The rest of the results didn't show significant differences. Conclusion: Only 6.5% of the patients that went to EPM-99mTc-SESTAMIBl in a 6 year-old lapse, were smaller than 40 years. 71% of them was referred by prechordal pain in who almost the half it was evidenced Cl or IAM.

    Full Text Available Extrathymic CD4+CD8+ double-positive (DP T cells are increased in some pathophysiological conditions, including infectious diseases. In the murine model of Chagas disease, it has been shown that the protozoan parasite Trypanosoma cruzi is able to target the thymus and induce alterations of the thymic microenvironment and the lymphoid compartment. In the acute phase, this results in a severe atrophy of the organ and early release of DP cells into the periphery. To date, the effect of the changes promoted by the parasite infection on thymic central tolerance has remained elusive. Herein we show that the intrathymic key elements that are necessary to promote the negative selection of thymocytes undergoing maturation during the thymopoiesis remains functional during the acute chagasic thymic atrophy. Intrathymic expression of the autoimmune regulator factor (Aire and tissue-restricted antigen (TRA genes is normal. In addition, the expression of the proapoptotic Bim protein in thymocytes was not changed, revealing that the parasite infection-induced thymus atrophy has no effect on these marker genes necessary to promote clonal deletion of T cells. In a chicken egg ovalbumin (OVA-specific T-cell receptor (TCR transgenic system, the administration of OVA peptide into infected mice with thymic atrophy promoted OVA-specific thymocyte apoptosis, further indicating normal negative selection process during the infection. Yet, although the intrathymic checkpoints necessary for thymic negative selection are present in the acute phase of Chagas disease, we found that the DP cells released into the periphery acquire an activated phenotype similar to what is described for activated effector or memory single-positive T cells. Most interestingly, we also demonstrate that increased percentages of peripheral blood subset of DP cells exhibiting an activated HLA-DR+ phenotype are associated with severe cardiac forms of human chronic Chagas disease. These cells may

    Full Text Available Reactivation of chronic chagasic patients may occur upon use of immunosuppressive drugs related to kidney or heart transplantation or when they are affected by concomitant HIV infection. This recrudescence, however, does not occur in all chagasic patients exposed to immunosuppressive agents. We therefore investigated the influence of Trypanosoma cruzi strains in the recrudescence of the parasitism in mice at the chronic phase treated with cyclophosphamide, an immunosuppressor that blocks lymphocytes DNA synthesis and therefore controls B cells response. A large variation was detected in the percentages of newly established acute phases in the groups of mice inoculated with the different strains. We suggest that reactivation of chronic T. cruzi infections is influenced by the parasite intrinsic characteristics, a phenomenon that might occur in the human disease.

    The reactivation of Chagas disease in HIV infected patients presents high mortality and morbidity. We present the case of a female patient with confirmed Chagasic meningoencephalitis as AIDS-defining illness. Interestingly, her TCD4+ lymphocyte cell count was 318 cells/mm3. After two months of induction therapy, one year of maintenance with benznidazol, and early introduction of highly active antiretroviral therapy (HAART), the patient had good clinical, parasitological and radiological evolution. We used a qualitative polymerase chain reaction for the monitoring of T. cruzi parasitemia during and after the treatment. We emphasize the potential value of molecular techniques along with clinical and radiological parameters in the follow-up of patients with Chagas disease and HIV infection. Early introduction of HAART, prolonged induction and maintenance of antiparasitic therapy, and its discontinuation are feasible, in the current management of reactivation of Chagas disease.

Confirmou-se que as lesões mais intensas localizavam-se na muscular própria e no plexo de Auerbach. Na primeira, as principais alterações foram miosite e fibrose e nos gânglios mientéricos observou-se inflamação e despopulação neuronal, maior nos esôfagos dos chagásicos com dilatação em relação aos sem dilatação e destes em relação aos controles. Entretanto, foram vistos esôfagos de calibre normal, com intensa denervação. Conclui-se que parecem ser múltiplos os fatores que desencadeiam a esofagopatia, especialmente, o ME. A pesquisa de parasitas em oito esófagos com mega e em oito sem ME foi positiva somente em quatro casos, do primeiro grupo.

    Full Text Available Reports on children presenting symptoms compatible with the chronic phase of Chagas disease are sporadic. We report a case of a 7-year-old boy who had megaesophagus and megacolon, both of them a consequence of the trypanosomiasis. The etiology was established by means of laboratory and histological features. Based on epidemiological data, the authors concluded that vertical transmission was the most probable route of acquisition. This diagnosis should be considered in children presenting similar complaints, even those living away from endemic areas.

    Chagas' disease, caused by Trypanosoma cruzi infection, is one of the main causes of death due to heart failure in Latin American countries. Benznidazole, the chemotherapeutic agent most often used for the treatment of chagasic patients, is highly toxic and has limited efficacy, especially in the chronic phase of the disease. In the present study we used a mouse model of chronic Chagas' disease to investigate the effects of benznidazole treatment during the chronic phase on disease progression. The hearts of benznidazole-treated mice had decreased parasitism and myocarditis compared to the hearts of untreated chagasic mice. Both groups of Trypanosoma cruzi-infected mice had significant alterations in their electrocardiograms compared to those of the healthy mice. However, untreated mice had significantly higher cardiac conduction disturbances than benznidazole-treated mice, including intraventricular conduction disturbances, atrioventricular blocks, and extrasystoles. The levels of antibodies against T. cruzi antigens (epimastigote extract, P2β, and trans-sialidase) as well as antibodies against peptides of the second extracellular loops of β1-adrenergic and M2-muscarinic cardiac receptors were also lower in the sera from benznidazole-treated mice than in the sera from untreated mice. These results demonstrate that treatment with benznidazole in the chronic phase of infection prevents the development of severe chronic cardiomyopathy, despite the lack of complete parasite eradication. In addition, our data highlight the role of parasite persistence in the development of chronic Chagas' disease and reinforce the importance of T. cruzi elimination in order to decrease or prevent the development of severe chagasic cardiomyopathy.

    Background: The outcome of Chagas disease patients after receiving implantable cardioverter defibrillator (ICD) is still controversial. Objective: To compare clinical outcomes after ICD implantation in patients with chronic Chagas cardiomyopathy (CCC) and ischemic heart disease (IHD). Methods: Prospective study of a population of 153 patients receiving ICD (65 with CCC and 88 with IHD). The devices were implanted between 2003 and 2011. Survival rates and event-free survival were compared. Results: The groups were similar regarding sex, functional class and ejection fraction. Ischemic patients were, on average, 10 years older than CCC patients (p < 0.05). Patients with CCC had lower schooling and monthly income than IHD patients (p < 0.05). The number of appropriate therapies was 2.07 higher in CCC patients, who had a greater incidence of appropriate shock (p < 0.05). Annual mortality rate and electrical storm incidence were similar in both groups. There was no sudden death in CCC patients, and only one in IHD patients. Neither survival time (p = 0.720) nor event-free survival (p = 0.143) significantly differed between the groups. Conclusion: CCC doubles the risk of receiving appropriate therapies as compared to IHD, showing the greater complexity of arrhythmias in Chagas patients. PMID:27411097

    Full Text Available Chagasic megaesophagus is a chronic disease that courses with progressive dysphagia, regurgitation and protein-calorie malnutrition. Advanced or recurrent megaesophagus can be treated with Serra Dória’s operation (cardioplasty, partial gastrectomy and gastrojejunal Roux-en-Y anastomosis. A nutritional evaluation was performed on 27 patients (mean age 58 ± 10 years with chagasic megaesophagus at admission and after postoperative day 90. The nutritional state was assessed through global subjective nutritional evaluation (GSNE, anthropometry and laboratorial exams, besides the analysis of alimentary intake. In the preoperative period, GSNE pointed to malnutrition in 2/3 patients, while the anthropometric and laboratorial evaluation revealed that over 60% of the patients had protein-calorie malnutrition of the marasmic type. The preoperative nutritional state as evaluated by GSNE did not correlate with complications or postoperative mortality. The postoperative evaluation showed an increase in the intake of proteins, recovery in the body mass index and a reduction in the hemoglobin levels of the peripheral blood.El megaesófago debido a la enfermedad de Chagas es una enfermedad crónica que cursa con disfagia progresiva, regurgitación y malnutrición proteínico-calórica.

    We have previously demonstrated that immune responses in subjects with chronic Trypanosoma cruzi infection display features common to other persistent infections with signs of T cell exhaustion. Alterations in cytokine receptor signal transduction have emerged as one of the cell-intrinsic mechanisms of T cell exhaustion. Herein, we performed an analysis of the expression of IL-7R components (CD127 and CD132) on CD4+ and CD8+ T cells, and evaluated IL-7-dependent signaling events in patients at different clinical stages of chronic chagasic heart disease. Subjects with no signs of cardiac disease showed a decrease in CD127+CD132+ cells and a reciprocal gain of CD127-CD132+ in CD8+ and CD4+ T cells compared to either patients exhibiting heart enlargement or uninfected controls. T. cruzi infection, in vitro, was able to stimulate the downregulation of CD127 and the upregulation of CD132 on T cells. IL-7-induced phosphorylation of STAT5 as well as Bcl-2 and CD25 expression were lower in T. cruzi-infected subjects compared with uninfected controls. The serum levels of IL-7 was also increased in chronic chagasic patients. The present study highlights perturbed IL-7/IL-7R T cell signaling through STAT5 as a potential mechanism of T cell exhaustion in chronic T. cruzi infection. PMID:25769928

  12. Analysis of the relationship cost-effectiveness of the myocardial gammagraphy studies and the impact to the total expenditure by diagnostic of ischemic cardiopathy

    International Nuclear Information System (INIS)

    Recent advances in pharmacology, diagnostic and invasive procedures provide a series of modalities that diminish the morbidity and increase the long term survival in the patients that have suffered a heart attack to myocardium. The stratification by risk is an essential element for the handling of the survivors of heart attack to myocardium. In their attention it is looked for to optimize the therapeutic benefit, to diminish the unnecessary diagnostic and therapeutic procedures and to improve the efficiency. For example, a coronariography in sick with heart attack to myocardium it is not cost-effective if not is clinically suitable. Of there that from the institutional point of view, this is, of the Mexican Institute of the Public Health, they are required of appropriate reference approaches and counter reference to grant to the sick person, the best service that is the one in this case the diagnostic and the handling of the ischemic cardiopathy with the smallest waste of resources. The estimation of the annual survival is the base of the stratification, it constitutes the angular stone of the early handling of the heart attack to myocardium. The goal for the clinical would be to identify patients with intermediate risk, since, this risk makes them candidates to therapy interventionist. As long as those with low risk won't require intervention. This would allow the decrease of rates by revenues of heart attack to myocardium, and therefore to diminish the hospital staying rates. The Nuclear Cardiology (myocardial gammagraphy) it is not the only invasive method available to evaluate the myocardial perfusion in sick in who coronary illness is suspected. When the myocardial gammagraphy is carried out in appropriate population, the cost it diminishes because it restricts the necessity of additional invasive evaluations. This because the nuclear cardiology has predictive value so much for the mortality like to detect myocardial viability. Based on these probabilities

    Full Text Available To describe the epidemiologic profile and prevalence of cardiopathy in 163 Trypanosoma cruzi serum positive blood donor candidates, a descriptive study was carried out between August, 1996 and November, 1997 at the Londrina State University Chagas Disease Outpatient Clinic. The profile found was: young, average age 42.95 ± 8.62 years; male (65%; Caucasian (84%; low level of schooling; low family income; agricultural worker (26%; born in the state of Paraná (67%; from rural areas (85%; migrated to the city (85%; and the vector as the main mechanism of transmission. During the clinical characterization a chronic cardiac form was found in 38% of the patients and classified as cardiac suggestive form in 21% and little suggestive of Chagas disease in 17%. No significant difference was found among age group distribution, sex and the presence of cardiac symptoms in patients with or without cardiopathy. This study emphasizes the importance of expanding medical services to areas with a greater prevalence of infected individuals, in a hierarchical manner and aiming at decentralization.Objetivando-se traçar o perfil epidemiológico e a prevalência de cardiopatia, realizou-se estudo descritivo em 163 candidatos a doador de sangue infectados por Trypanosoma cruzi, atendidos no período de agosto de 1996 a novembro de 1997 no ambulatório de doença de Chagas do Hospital de Clínicas da Universidade Estadual de Londrina.

    ón clínica tradicional. Para ello será necesario seguir mejorando la interpretabilidad clínica de los diversos cuestionarios de medición.The term health-related quality of life (HRQL is a concept related to the assessment of how the individual perceives health and that covers both objective and subjective aspects. Despite the lack of consensus about its definition, several tools have been developed for the measurement of HRQL in different pathologies, such as in the ischemic cardiopathy. These tools take into consideration different dimensions of the HRQL and are usually classified as generic or specific questionnaires. These tools must have certain features in order to be considered useful, allowing to record patient perceptions in a quantitative or semi-quantitatively way that might be communicated and used to describe, assess or compare. The assessment of HRQL is important due to the high relevance of this disease in terms of epidemiology and health care, and also in terms of the related psychological aspects that are not always duly considered by clinicians. We describe the most widely used generic and specific HRQL questionnaires in ischemic cardiopathy, indicating the dimensions covered by each of them. Finally, the main uses of the measurement of HRQL in the ischemic cardiopathy for the assessment of outcomes are reviewed, with reference to clinical trials and cardiac rehabilitation. It is stressed that the assessment of HRQL in the ischemic cardiopathy provides us with a final health outcome focused on the individual instead of the disease; focused on how the patient feels, regardless the clinical data. Hence, the assessment of HRQL in the ischemic cardiopathy is a tool aimed to promote a patient-focused health care and to provide information that complements the traditional clinical assessment. For this purpose, the clinical interpretability of the different assessment questionnaires should be further improved.

    Full Text Available The surface of human syncytiotrophoblast does not induce maternal blood platelet aggregation even though it is not an endothelium. It can be surmised that as occurs in endothelial injury the subcellular components of the syncytiotrophoblast may have pro-or antiaggregatory activity. During congenital Chagas' disease which is associated to trophoblast lesions, platelets may play a role in the development of T. cruzi-induced placentitis. In the present work the aggregatory behaviour of normal human blood platelets was recorded after their challenging with subcellular fractions of syncytiotrophoblast isolated from normal and chagasic women. Nuclear, Mitochondrial, Microsomal and Supernatant fractions isolated from normal and chagasic syncytiotrophoblast failed to induce per se any aggregatory reaction on platelets. When samples of platelet-rich plasma (PRP were preincubated with normal and chagasic nuclear fractions and then stimulated with collagen at threshold level (CT-PRP an inhibition of the aggregatory response was observed. Treatment of CT-PRP with normal and chagasic mitochondrial fractions induced inhibition of platelet aggregation whereas only chagasic fraction reduced latency time. Microsornal fraction from normal placentas showed no significant effects on platelet aggregation. It is concluded that subcellular fractions of normal human syncytiotrophoblast do not exhibit any effect on platelet aggregation, whereas those subcellular fractions enriched in intracellular membrane components isolated from chagasic placentas inhibit platelet aggregation.A superficie do sinciciotrofoblasto humano não induz agregação das plaquetas maternas apesar de não ser um endotélio.

    Full Text Available BACKGROUND: The causative agent of Chagas disease, Trypanosoma cruzi, is divided into 6 Discrete Typing Units (DTU: Tc I, IIa, IIb, IIc, IId and IIe. In order to assess the relative pathogenicities of different DTUs, blood samples from three different clinical groups of chronic Chagas disease patients (indeterminate, cardiac, megacolon from Bolivia were analyzed for their circulating parasites lineages using minicircle kinetoplast DNA polymorphism. METHODS AND FINDINGS: Between 2000 and 2007, patients sent to the Centro Nacional de Enfermedades Tropicales for diagnosis of Chagas from clinics and hospitals in Santa Cruz, Bolivia, were assessed by serology, cardiology and gastro-intestinal examinations. Additionally, patients who underwent colonectomies due to Chagasic magacolon at the Hospital Universitario Japonés were also included. A total of 306 chronic Chagas patients were defined by their clinical types (81 with cardiopathy, 150 without cardiopathy, 100 with megacolon, 144 without megacolon, 164 with cardiopathy or megacolon, 73 indeterminate and 17 cases with both cardiopathy and megacolon. DNA was extracted from 10 ml of peripheral venous blood for PCR analysis. The kinetoplast minicircle DNA (kDNA was amplified from 196 out of 306 samples (64.1%, of which 104 (53.3% were Tc IId, 4 (2.0% Tc I, 7 (3.6% Tc IIb, 1 (0.5% Tc IIe, 26 (13.3% Tc I/IId, 1 (0.5% Tc I/IIb/IId, 2 (1.0% Tc IIb/d and 51 (25.9% were unidentified. Of the 133 Tc IId samples, three different kDNA hypervariable region patterns were detected; Mn (49.6%, TPK like (48.9% and Bug-like (1.5%. There was no significant association between Tc types and clinical manifestations of disease. CONCLUSIONS: None of the identified lineages or sublineages was significantly associated with any particular clinical manifestations in the chronic Chagas patients in Bolivia.

    Full Text Available Twenty young male Cebus apella monkeys were infected with CAl Trypanosoma cruzi strain and reinfected with CA l or Tulahuen T.cruzi strains, with different doses and parasite source. Subpatent parasitemia was usually demonstrated in acute and chronic phases. Patent parasitemia was evident in one monkey in the acute phase and in four of them in the chronic phase after re-inoculations with high doses of CAl strain. Serological conversion was observed in all monkeys; titers were low, regardless of the methods used to investigate anti-T. cruzi specific antibodies. Higher titers were induced only when re-inoculations were perfomed with the virulent Tulahuén strain or high doses of CAl strain. Clinical electrocardiographic and ajmaline test evaluations did not reveal changes between infected and control monkeys. Histopathologically, cardiac lesions were always characterized by focal or multifocal mononuclear infiltrates and/or isolated fibrosis, as seen during the acute and chronic phases; neither amastigote nests nor active inflammation and fibrogenic processes characteristic of human acute and chronic myocarditis respectively, were observed. These morphological aspects more closely resemble those found in the "indeterminate phase" and contrast with the more diffuse and progressive pattern of the human chagasic myocarditis. All monkeys survived and no mortality was observed.

    Chagasic cardiomyopathy is a common disease in Latin America, however similar clinical pictures exist that can be confused with this, as they give negative results to the tests that detects T. cruzi, like non Chagasic rural endemic chronic cardiopathy, highly common in Venezuela. Using histopathology techniques, "idiopathic cardiomyopathy" is frequently found as the cause of death when the etiology of this disease is not known. This paper presents the case of a man of 26-years-old who died of dilated cardiomyopathy secondary to leptospirosis. Clinically, in addition to the cardiac failure, jaundice, hyperbilirubinemia, transaminases increase, proteinuria and hematuria were present. Initially it was suspected Chagasic cardiomyopathy but the epidemiologic background and the parasitologic and serologic tests for T. cruzi gave negative results. The dark field microscopy videorecording of blood and urine samples, argentic impregnation and immunohistochemistry tests as well as haemoculture in EMJH medium were positive for L. interrogans serovar Pomona. Postmortem we confirmed the presence of leptospira in different tissues through of histopathology, argentic impregnation, indirect immunofluorescence and immunohistochemistry. PMID:20191987

METHODS: Twelve men with ejection fractions <40% and CMC confirmed by a serological test were assessed. The six-minute walk test (6MWT was performed before and after administration of 50 mg of Sildenafil, with a 30 minute interval. Heart rate (HR, systolic blood pressure (SBP and diastolic blood pressure were taken and compared before and after each 6MWT. For statistical analysis purposes, the study was divided into four stages: before the 6MWT and administration of Sildenafil (S1; after the 6MWT but before the administration of Sildenafil (S2; after the administration of Sildenafil but before the 6MWT (S3; and after the administration of Sildenafil and the 6MWT (S4. RESULTS: Participant ages ranged from 47 to 68 years (57.6 ± 6.4.

METHOD: Thirty male Wistar rats received intrapericardic injection of CB 0.3% (CB animals and thirty similar animals received saline (C animals. After 15 days the animals were divided in three groups, with 10 CB-treated and 10 saline-treated animals each. Group I was submitted to radiological and morphologic studies. The cardiac shadow area (CSA and cardiothoracic index were calculated in roentgenograms with a semi-automatic image analysis system (MINI-MOP. The day after the animals were weighted and sacrificed with heart, liver and lung collected for histopathologic analysis. The animals of group II were submitted to a hemodynamic study. Measurements of blood pressure, heart rate and cardiac output were performed using the Cardiomax II termodilution system and a Termistor sensor. With the animals of the group III, the integrity of extrinsic parassympatic cardiac innervartion was examined by measuring heart rate response to electrical stimulation of the right vagus. Electrical activity was assessed by ECG. RESULTS: CB animals presented increases in cardiothoracic index, CSA, body and liver weight. In these animals the histopathologic analysis showed passive chronic congestion and reduction of the number of atrial neurons. In the hemodynamic study, total peripheral resistance and heart rate were similar in both groups, but blood pressure and cardiac index were reduced in the CB group. The vagal stimulation and ECG were similar in both groups. CONCLUSION: The Intrinsic Cardiac Nervous System denervation caused dilated cardiopathy in rats with left and right heart failure. The etiology of some dilated cardiopathies in human is largely unknown. Thisunpublished experimental model should provide future studies with the objective of elucidating the relationship between neuronal injures and heart disease.

    Full Text Available This work compared the time at which negative seroconversion was detected by conventional serology (CS and by the ELISA-F29 test on a cohort of chronic chagasic patients treated with nifurtimox or benznidazole. A retrospective study was performed using preserved serum from 66 asymptomatic chagasic adults under clinical supervision, and bi-annual serological examinations over a mean follow-up of 23 years. Twenty nine patients received trypanocide treatment and 37 remained untreated. The ELISA-F29 test used a recombinant antigen which was obtained by expressing the Trypanosoma cruzi flagellar calcium-binding protein gene in Escherichia coli. Among the untreated patients, 36 maintained CS titers. One patient showed a doubtful serology in some check-ups. ELISA-F29 showed constant reactivity in 35 out of 37 patients and was negative for the patient with fluctuating CS. The treated patients were divided into three groups according to the CS titers: in 13 they became negative; in 12 they decreased and in four they remained unchanged. ELISA-F29 was negative for the first two groups. The time at which negativization was detected was significantly lower for the ELISA-F29 test than for CS, 14.5 ± 5.7 and 22 ± 4.9 years respectively. Negative seroconversion was observed in treated patients only. The results obtained confirm that the ELISA-F29 test is useful as an early indicator of negative seroconversion in treated chronic patients.

    Full Text Available Objective: To compare the diagnostic performance of seven methods to determine Trypanosoma cruzi infection in patients with chronic Chagas disease.Methods: Analytical study, using the case-control design, which included 205 people (patients with Chagasic cardiomyopathy, n= 100; control group, n= 105. Three enzyme linked immunosorbent assays, one indirect hemagglutination assay and one immunochromatographic test were assessed. Additionally, DNA amplification was performed via the PCR method using kinetoplast and nuclear DNA as target sequences. For the comparative analysis of diagnostic tests, the parameters used were sensitivity, specificity, positive and negative predictive values, Receiver Operator Characteristic (ROC, positive and negative likelihood ratio, as well as κ quality analysis.Results: The commercial Bioelisa Chagas test showed the highest sensitivity (98%, specificity (100%, and positive and negative predictive values; additionally it had the highest discriminatory power. Otherwise, the amplification of T. cruzi DNA in blood samples showed low values of sensitivity (kinetoplast DNA= 51%, nuclear DNA= 22%, but high values of specificity (100%, and moderate to low discriminatory ability.Conclusion: The comparative analysis among the different methods suggests that the diagnostic strategy of T. cruzi infection in patients with chronic Chagas disease can be performed using ELISA assays based on recombinant proteins and/or synthetic peptides, which show higher diagnosis performance and can confirm and exclude the diagnosis of T. cruzi infection. The molecular methods show poor performance when used in the diagnosis of patients with chronic Chagas disease.

    1984-05-01

    Chronicity in psychopathology is indicative of a term, a decay. Chronicization only leads the way to this term. Here, chronicization is taken literally as an inscription in the time course of delusions. The mechanism of systematization seems to be a central mark in the approach to chronic delusions. It is not an alienation or an irreversible closing but an attempted accommodation with reality in the life of psychotic subjects, irrespective of the delusional structure. The role of therapy and drug treatment as a follow-up may in that case assume another meaning.

Todos os animais em estudo bem como os controles receberam atenolol e atropina. No estádio agudo, a frequência cardíaca basal dos animais infectados foi significativamente maior que a dos controles. A resposta cronotrópica negativa pela administração de atenolol foi quatro vezes maior nos animais infectados. No estádio sub-agudo, a frequência cardíaca basal e a resposta cronotrópica ao atenolol e atropina foi similar nos dois grupos do estudo.

    Full Text Available The effect of an 8 hour-period of water deprivation on fluid and electrolyte renal excretion was investigated in male Wistar rats infected with the strain São Felipe (12SF of Trypanosoma cruzi, in comparison with age and sex matched non-infected controls. The median percent reductions in the urinary flow (-40% v -63% and excretion ofsodium (-57% v-79% were smaller in chagasic than in control rats, respectively. So, chagasic rats excreted more than controls. On the other hand, the median percent decrement in the clearance of creatinine was higher in chagasic (-51% than in controls (-39%. Thus, chagasic rats showed some disturbed renal hydroelectrolytic responses to water deprivation, expressed by smaller conservation, or higher excretion of water and sodium in association with smaller glomerularfiltration rate. This fact denoted an elevation in the fractional excretion of sodium and water.

    Full Text Available Background. Chagas disease (CD is characterized by parasite persistence and immunological unbalance favoring systemic inflammatory profile. Chronic chagasic cardiomyopathy, the main manifestation of CD, occurs in a TNF-enriched milieu and frequently progresses to heart failure. Aim of the Study. To challenge the hypothesis that TNF plays a key role in Trypanosoma cruzi-induced immune deregulation and cardiac abnormalities, we tested the effect of the anti-TNF antibody Infliximab in chronically T. cruzi-infected C57BL/6 mice, a model with immunological, electrical, and histopathological abnormalities resembling Chagas’ heart disease. Results. Infliximab therapy did not reactivate parasite but reshaped the immune response as reduced TNF mRNA expression in the cardiac tissue and plasma TNF and IFNγ levels; diminished the frequency of IL-17A+ but increased IL-10+ CD4+ T-cells; reduced TNF+ but augmented IL-10+ Ly6C+ and F4/80+ cells. Further, anti-TNF therapy decreased cytotoxic activity but preserved IFNγ-producing VNHRFTLV-specific CD8+ T-cells in spleen and reduced the number of perforin+ cells infiltrating the myocardium. Importantly, Infliximab reduced the frequency of mice afflicted by arrhythmias and second degree atrioventricular blocks and decreased fibronectin deposition in the cardiac tissue. Conclusions. Our data support that TNF is a crucial player in the pathogenesis of Chagas’ heart disease fueling immunological unbalance which contributes to cardiac abnormalities.

    coronary artery disease (lesions > 50% in a specific population of patients with Chagas cardiomyopathy in HF functional class III and IV, who had no previous coronary events. METHODS: Coronary angiography was performed in 61 consecutive patients with Chagasic cardiomyopathy, in heart failure functional class III and IV, to exclude coronary artery disease. These patients were part of the Cell Therapy Study in Heart Diseases protocol, which required the coronary angiography to be carried out before stem cells were injected. Risk factors for atherosclerosis also analyzed in this population were: age, arterial hypertension, diabetes, dyslipidemia, smoking and overweight. RESULTS: mean age was 51.6 + 9.6 years and 65.5% (n = 40 of them were males. The prevalence of coronary disease in this population was 1.6% (1. The prevalence of risk factors were: arterial hypertension 18% (11, smoking 59% (36, diabetes 1.6% (1 and dyslipidemia, 6.5% (4. CONCLUSION: The prevalence of asymptomatic coronary artery disease in patients with severe heart failure due to Chagas disease is low and among the risk factors for coronary heart disease, smoking was the most prevalent.

    Full Text Available BACKGROUND: Chagas disease, caused by infection with the protozoan Trypanosoma cruzi, remains a serious public health issue in Latin America. Genetically diverse, the species is sub-divided into six lineages, known as TcI-TcVI, which have disparate geographical and ecological distributions. TcII, TcV, and TcVI are associated with severe human disease in the Southern Cone countries, whereas TcI is associated with cardiomyopathy north of the Amazon. T. cruzi persists as a chronic infection, with cardiac and/or gastrointestinal symptoms developing years or decades after initial infection. Identifying an individual's history of T. cruzi lineage infection directly by genotyping of the parasite is complicated by the low parasitaemia and sequestration in the host tissues. METHODOLOGY/PRINCIPAL FINDINGS: We have applied here serology against lineage-specific epitopes of the T. cruzi surface antigen TSSA, as an indirect approach to allow identification of infecting lineage. Chagasic sera from chronic patients from a range of endemic countries were tested by ELISA against synthetic peptides representing lineage-specific TSSA epitopes bound to avidin-coated ELISA plates via a biotin labelled polyethylene glycol-glycine spacer to increase rotation and ensure each amino acid side chain could freely interact with their antibodies. 79/113 (70% of samples from Brazil, Bolivia, and Argentina recognised the TSSA epitope common to lineages TcII/TcV/TcVI. Comparison with clinical information showed that a higher proportion of Brazilian TSSApep-II/V/VI responders had ECG abnormalities than non-responders (38% vs 17%; p<0.0001. Among northern chagasic sera 4/20 (20% from Ecuador reacted with this peptide; 1/12 Venezuelan and 1/34 Colombian samples reacted with TSSApep-IV. In addition, a proposed TcI-specific epitope, described elsewhere, was demonstrated here to be highly conserved across lineages and therefore not applicable to lineage-specific serology. CONCLUSIONS

    Full Text Available This paper describes the development of experimental Chagas' disease in 64 out-bred young dogs. Twenty-nine animals were inoculated with the Be-62 and 35 with Be-78 Trypanosoma cruzi strains. Twenty-six were infected with blood trypomastigotes by different inoculation routes and 38 with metacyclic trypomastigotes from the vector via the conjunctival route. Twenty of the 26 dogs infected with blood trypomastigotes were autopsied during the acute phase. Eleven died spontaneously and nine were sacrificed. Six remained alive until they died suddenly (two or were autopsied (four. Twelve of the 38 dogs infected with metacyclic trypomastigotes evolved naturally to the chronic phase and remained alive for 24-48 months. The parasitemia, clinical aspects and serology (IgM and IgG as well as electrocardiogram, hemogram and heart anatomo-histopathologic patterns of acute and chronic cardiac forms of Chagas' disease as seen in human infections, were reproduced. The most important finding is the reproductibility of diffuse fibrosing chronic chagasic cardiopathy in all dogs infected with Be-78 T. cruzi strain autopsied between the 90th and 864th days of infection. Thus, the dog can be considered as a suitable experimental model to study Chagas' disease according to the requisites of the World Health Organization (1984.

The study consisted of paired sex and age matched controls. Two hundred and eight pairs were analysed. Either ischemic or hemorrhagic strokes were found in 41 (19.7%) of the chagasics and in 55 (26.4%) of the non-chagasic, a difference not significant at the level of 5%. Twelve (75%) of the former had infarcts and 4 (25%) had brain hemorrhage; five (31.3%) of the non-chagasics had ischemic strokes and 11 (68.7%) had hemorrhagic strokes. The differences were significant to the level of 5%. The results indicate a high frequency of ischemic strokes in human Chagas' disease and demonstrate a lesser frequency of hemorrhagic stroke in chagasics when compared with non-chagasics.

    The performance of serologic tests in chronic Chagas disease diagnosis largely depends on the type and quality of the antigen preparations that are used for detection of anti-Trypanosoma cruzi antibodies. Whole-cell T. cruzi extracts or recombinant proteins have shown variation in the performance and cross-reactivity. Synthetic chimeric proteins comprising fragments of repetitive amino acids of several different proteins have been shown to improve assay performances to detect Chagasic infections. Here, we describe the production of four chimeric T. cruzi proteins and the assessment of their performance for diagnostic purposes. Circular Dichroism spectra indicated the absence of well-defined secondary structures, while polydispersity evaluated by Dynamic Light Scattering revealed only minor aggregates in 50 mM carbonate-bicarbonate (pH 9.6), demonstrating that it is an appropriate buffering system for sensitizing microplates. Serum samples from T. cruzi-infected and non-infected individuals were used to assess the performance of these antigens for detecting antibodies against T. cruzi, using both enzyme-linked immunosorbent assay and a liquid bead array platform. Performance parameters (AUC, sensitivity, specificity, accuracy and J index) showed high diagnostic accuracy for all chimeric proteins for detection of specific anti-T. cruzi antibodies and differentiated seropositive individuals from those who were seronegative. Our data suggest that these four chimeric proteins are eligible for phase II studies. PMID:27517281

    Recent advances in pharmacology, diagnostic and invasive procedures provide a series of modalities that diminish the morbidity and increase the long term survival in the patients that have suffered a heart attack to myocardium. The stratification by risk is an essential element for the handling of the survivors of heart attack to myocardium. In their attention it is looked for to optimize the therapeutic benefit, to diminish the unnecessary diagnostic and therapeutic procedures and to improve the efficiency. For example, a coronariography in sick with heart attack to myocardium it is not cost-effective if not is clinically suitable. Of there that from the institutional point of view, this is, of the Mexican Institute of the Public Health, they are required of appropriate reference approaches and counter reference to grant to the sick person, the best service that is the one in this case the diagnostic and the handling of the ischemic cardiopathy with the smallest waste of resources. The estimation of the annual survival is the base of the stratification, it constitutes the angular stone of the early handling of the heart attack to myocardium. The goal for the clinical would be to identify patients with intermediate risk, since, this risk makes them candidates to therapy interventionist. As long as those with low risk won't require intervention. This would allow the decrease of rates by revenues of heart attack to myocardium, and therefore to diminish the hospital staying rates. The Nuclear Cardiology (myocardial gammagraphy) it is not the only invasive method available to evaluate the myocardial perfusion in sick in who coronary illness is suspected. When the myocardial gammagraphy is carried out in appropriate population, the cost it diminishes because it restricts the necessity of additional invasive evaluations. This because the nuclear cardiology has predictive value so much for the mortality like to detect myocardial viability. Based on these

  18. Genome-wide screening and identification of new Trypanosoma cruzi antigens with potential application for chronic Chagas disease diagnosis.

    Directory of Open Access Journals (Sweden)

    João Luís Reis-Cunha

    Full Text Available The protozoan Trypanosoma cruzi is the etiologic agent of Chagas disease, an infection that afflicts approximately 8 million people in Latin America. Diagnosis of chronic Chagas disease is currently based on serological tests because this condition is usually characterized by high anti-T. cruzi IgG titers and low parasitemia. The antigens used in these assays may have low specificity due to cross reactivity with antigens from related parasite infections, such as leishmaniasis, and low sensitivity caused by the high polymorphism among T. cruzi strains. Therefore, the identification of new T. cruzi-specific antigens that are conserved among the various parasite discrete typing units (DTUs is still required. In the present study, we have explored the hybrid nature of the T. cruzi CL Brener strain using a broad genome screening approach to select new T. cruzi antigens that are conserved among the different parasite DTUs and that are absent in other trypanosomatid species. Peptide arrays containing the conserved antigens with the highest epitope prediction scores were synthesized, and the reactivity of the peptides were tested by immunoblot using sera from C57BL/6 mice chronically infected with T. cruzi strains from the TcI, TcII or TcVI DTU. The two T. cruzi proteins that contained the most promising peptides were expressed as recombinant proteins and tested in ELISA experiments with sera from chagasic patients with distinct clinical manifestations: those infected with T. cruzi from different DTUs and those with cutaneous or visceral leishmaniasis. These proteins, named rTc_11623.20 and rTc_N_10421.310, exhibited 94.83 and 89.66% sensitivity, 98.2 and 94.6% specificity, respectively, and a pool of these 2 proteins exhibited 96.55% sensitivity and 98.18% specificity. This work led to the identification of two new antigens with great potential application in the diagnosis of chronic Chagas disease.

    ventricular premature beats, with right ventricle outflow tract morphology (RVOT and no apparent structural cardiopathy. METHODS: Ninety patients (66 women, mean age 40.2±16.95 years of age with monomorphic premature beats originated at RVOT were evaluated prospectively. Fifty-four patients reported syncopes or near-syncopes associated to palpitations or not; twenty-seven presented palpitations with no pre-syncope or syncope, and nine were asymptomatic. All patients were submitted to echocardiogram, high resolution ECG and cardiac MRI to rule out structural cardiopathy, to exertion test to rule out adrenergic dependent ventricular tachycardia, and ECG prolonged outpatient monitoring (Holter and symptomatic events monitor to correlate symptoms and ventricular arrhythmias. Investigation on the susceptibility to neurocardiogenic syncope was evaluated by Tilt Table Test (TTT. Groups were compared regarding gender, age, premature beats frequency and complexity, at exertion or not, TTT results and clinical course. RESULTS: In the syncope and pre-syncope groups, TTT was positive for 38% of cases, and in groups with palpitations and assymptomatics, it was positive for 11% (p = 0.0257. After recommendations and treatment of neurocardiogenic syncope, 85% of syncope and pre-syncope patients and positive TTT was asymptomatic along the 40-month follow-up. Two patients with syncope and negative TTT presented spontaneous, sustained ventricular tachycardia during clinic course. CONCLUSION: The prevalence of neurocardiogenic syncope in patients with idiopathic RVOT premature beats is high. Patients with recurrent, unexplained syncope and idiopathic VE must be kept under investigation.

    Full Text Available Chronic urticaria (CU is a disturbing allergic condition of the skin. Although frequently benign, it may sometimes be a red flag sign of a serious internal disease. A multitude of etiologies have been implicated in the causation of CU, including physical, infective, vasculitic, psychological and idiopathic. An autoimmune basis of most of the ′idiopathic′ forms is now hypothesized. Histamine released from mast cells is the major effector in pathogenesis and it is clinically characterized by wheals that have a tendency to recur. Laboratory investigations aimed at a specific etiology are not always conclusive, though may be suggestive of an underlying condition. A clinical search for associated systemic disease is strongly advocated under appropriate circumstances. The mainstay of treatment remains H1 antihistaminics. These may be combined with complementary pharmacopeia in the form of H2 blockers, doxepin, nifedipine and leukotriene inhibitors. More radical therapy in the form of immunoglobulins, plasmapheresis and cyclophosphamide may be required for recalcitrant cases. Autologous transfusion and alternative remedies like acupuncture have prospects for future. A stepwise management results in favorable outcomes. An update on CU based on our experience with patients at a tertiary care centre is presented.

    This study aimed to evaluate well-documented diagnostic antigens, named B13, 1F8 and JL7 recombinant proteins, as potential markers of seroconversion in treated chagasic patients. Prospective study, involving 203 patients treated with benznidazole, was conducted from endemic areas of northern Argentina. Follow-up was possible in 107 out of them and blood samples were taken for serology and PCR assays before and 2, 3, 6, 12, 24 and 36 months after treatment initiation. Reactivity against Trypanosoma cruzi lysate and recombinant antigens was measured by ELISA. The rate of decrease of antibody titers showed nonlinear kinetics with an abrupt drop within the first three months after initiation of treatment for all studied antigens, followed by a plateau displaying a low decay until the end of follow-up. At this point, anti-B13, anti-1F8 and anti-JL7 titers were relatively close to the cut-off line, while anti-T. cruzi antibodies still remained positive. At baseline, 60.8% (45/74) of analysed patients tested positive for parasite DNA by PCR and during the follow-up period in 34 out of 45 positive samples (75.5%) could not be detected T. cruzi DNA. Our results suggest that these antigens might be useful as early markers for monitoring antiparasitic treatment in chronic Chagas disease. PMID:27223650

    Chronic inflammation is the basis of various chronic illnesses including cancer and vascular diseases. However, much has yet to be learned how inflammation becomes chronic. Prostaglandins (PGs) are well established as mediators of acute inflammation, and recent studies in experimental animals have provided evidence that they also function in transition to and maintenance of chronic inflammation. One role PGs play in such processes is amplification of cytokine signaling. As such, PGs can facil...

    2006-01-01

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    Helicobacter pylori is the main aetiologic factor for chronic gastritis worldwide. The degree of inflammation and the evolution of this form of chronic gastritis can vary largely depending on bacterial virulence factors, host susceptibility factors and environmental conditions. Autoimmune gastritis is another cause of chronic inflammation in the stomach, which can occur in all age groups. This disease presents typically with vitamin B12 deficiency and pernicious anaemia. The presence of anti-parietal cell antibodies is highly specific for the diagnosis. The role of H. pylori as a trigger for autoimmune gastritis remains uncertain. Other rare conditions for chronic gastritis are chronic inflammatory conditions such as Crohn's disease or on the background of lymphocytic or collagenous gastroenteropathies. PMID:25439069

  3. [Chronic migraine: treatment].

    2012-04-10

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    Stevens, Whitney W; Lee, Robert J; Schleimer, Robert P; Cohen, Noam A

    2015-12-01

    There are a variety of medical conditions associated with chronic sinonasal inflammation, including chronic rhinosinusitis (CRS) and cystic fibrosis. In particular, CRS can be divided into 2 major subgroups based on whether nasal polyps are present or absent. Unfortunately, clinical treatment strategies for patients with chronic sinonasal inflammation are limited, in part because the underlying mechanisms contributing to disease pathology are heterogeneous and not entirely known. It is hypothesized that alterations in mucociliary clearance, abnormalities in the sinonasal epithelial cell barrier, and tissue remodeling all contribute to the chronic inflammatory and tissue-deforming processes characteristic of CRS. Additionally, the host innate and adaptive immune responses are also significantly activated and might be involved in pathogenesis. Recent advancements in the understanding of CRS pathogenesis are highlighted in this review, with special focus placed on the roles of epithelial cells and the host immune response in patients with cystic fibrosis, CRS without nasal polyps, or CRS with nasal polyps.

    Khadilkar Satish

    2011-01-01

    Full Text Available The spectrum of chronic dysimmune neuropathies has widened well beyond chronic demyelinating polyradiculoneuropathy (CIDP. Pure motor (multifocal motor neuropathy, sensorimotor with asymmetrical involvement (multifocal acquired demylinating sensory and motor neuropathy, exclusively distal sensory (distal acquired demyelinating sensory neuropathy and very proximal sensory (chronic immune sensory polyradiculopathy constitute the variants of CIDP. Correct diagnosis of these entities is of importance in terms of initiation of appropriate therapy as well as prognostication of these patients. The rates of detection of immune-mediated neuropathies with monoclonal cell proliferation (monoclonal gammopathy of unknown significance, multiple myeloma, etc. have been facilitated as better diagnostic tools such as serum immunofixation electrophoresis are being used more often. Immune neuropathies associated with malignancies and systemic vasculitic disorders are being defined further and treated early with better understanding of the disease processes. As this field of dysimmune neuropathies will evolve in the future, some of the curious aspects of the clinical presentations and response patterns to different immunosuppressants or immunomodulators will be further elucidated. This review also discusses representative case studies.

    Abstract Idiopathic chronic eosinophilic pneumonia (ICEP) is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than ...

  4. Hypertension in Chronic Glomerulonephritis.

    Ihm, Chun-Gyoo

    2015-12-01

    Chronic glomerulonephritis (GN), which includes focal segmental glomerulosclerosis and proliferative forms of GN such as IgA nephropathy, increases the risk of hypertension. Hypertension in chronic GN is primarily volume dependent, and this increase in blood volume is not related to the deterioration of renal function. Patients with chronic GN become salt sensitive as renal damage including arteriolosclerosis progresses and the consequent renal ischemia causes the stimulation of the intrarenal renin-angiotensin-aldosterone system(RAAS). Overactivity of the sympathetic nervous system also contributes to hypertension in chronic GN. According to the KDIGO guideline, the available evidence indicates that the target BP should be ≤140mmHg systolic and ≤90mmHg diastolic in chronic kidney disease patients without albuminuria. In most patients with an albumin excretion rate of ≥30mg/24 h (i.e., those with both micro-and macroalbuminuria), a lower target of ≤130mmHg systolic and ≤80mmHg diastolic is suggested. The use of agents that block the RAAS system is recommended or suggested in all patients with an albumin excretion rate of ≥30mg/ 24 h. The combination of a RAAS blockade with a calcium channel blocker and a diuretic may be effective in attaining the target BP, and in reducing the amount of urinary protein excretion in patients with chronic GN.

    Chronic Chagasic patient immunoglobulins (CChP-IgGs) recognize an acidic amino acid cluster at the second extracellular loop (el2) of cardiac M(2)-muscarinic acetylcholine receptors (M(2)AChRs). These residues correspond to a common binding site for various allosteric agents. We characterized the nature of the M(2)AChR/CChP-IgG interaction in functional and radioligand binding experiments applying the same mainstream strategies previously used for the characterization of other allosteric agents. Dose-response curves of acetylcholine effect on heart rate were constructed with data from isolated heart experiments in the presence of CChP or normal blood donor (NBD) sera. In these experiments, CChP sera but not NBD sera increased the efficacy of agonist action by augmenting the onset of bradyarrhythmias and inducing a Hill slope of 2.5. This effect was blocked by gallamine, an M(2)AChR allosteric antagonist. Correspondingly, CChP-IgGs increased acetylcholine affinity twofold and showed negative cooperativity for [(3)H]-N-methyl scopolamine ([(3)H]-NMS) in allosterism binding assays. A peptide corresponding to the M(2)AChR-el2 blocked this effect. Furthermore, dissociation assays showed that the effect of gallamine on the [(3)H]-NMS off-rate was reverted by CChP-IgGs. Finally, concentration-effect curves for the allosteric delay of W84 on [(3)H]-NMS dissociation right shifted from an IC(50) of 33 nmol/L to 78 nmol/L, 992 nmol/L, and 1670 nmol/L in the presence of 6.7 x 10(- 8), 1.33 x 10(- 7), and 2.0 x 10(- 7) mol/L of anti-el2 affinity-purified CChP-IgGs. Taken together, these findings confirmed a competitive interplay of these ligands at the common allosteric site and revealed the novel allosteric nature of the interaction of CChP-IgGs at the M(2)AChRs as a positive cooperativity effect on acetylcholine action.

    Full Text Available Abstract Hereditary chronic pancreatitis (HCP is a very rare form of early onset chronic pancreatitis. With the exception of the young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. As well, diagnostic criteria and treatment of HCP resemble that of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile duct and duodenal obstruction, and rarely pancreatic cancer. Fortunately, most patients have a mild disease. Mutations in the PRSS1 gene, encoding cationic trypsinogen, play a causative role in chronic pancreatitis. It has been shown that the PRSS1 mutations increase autocatalytic conversion of trypsinogen to active trypsin, and thus probably cause premature, intrapancreatic trypsinogen activation disturbing the intrapancreatic balance of proteases and their inhibitors. Other genes, such as the anionic trypsinogen (PRSS2, the serine protease inhibitor, Kazal type 1 (SPINK1 and the cystic fibrosis transmembrane conductance regulator (CFTR have been found to be associated with chronic pancreatitis (idiopathic and hereditary as well. Genetic testing should only be performed in carefully selected patients by direct DNA sequencing and antenatal diagnosis should not be encouraged. Treatment focuses on enzyme and nutritional supplementation, pain management, pancreatic diabetes, and local organ complications, such as pseudocysts, bile duct or duodenal obstruction. The disease course and prognosis of patients with HCP is unpredictable. Pancreatic cancer risk is elevated. Therefore, HCP patients should strongly avoid environmental risk factors for pancreatic cancer.

  9. A human type 5 adenovirus-based Trypanosoma cruzi therapeutic vaccine re-programs immune response and reverses chronic cardiomyopathy.

    2015-01-01

    Full Text Available Chagas disease (CD, caused by the protozoan Trypanosoma cruzi, is a prototypical neglected tropical disease. Specific immunity promotes acute phase survival. Nevertheless, one-third of CD patients develop chronic chagasic cardiomyopathy (CCC associated with parasite persistence and immunological unbalance. Currently, the therapeutic management of patients only mitigates CCC symptoms. Therefore, a vaccine arises as an alternative to stimulate protective immunity and thereby prevent, delay progression and even reverse CCC. We examined this hypothesis by vaccinating mice with replication-defective human Type 5 recombinant adenoviruses (rAd carrying sequences of amastigote surface protein-2 (rAdASP2 and trans-sialidase (rAdTS T. cruzi antigens. For prophylactic vaccination, naïve C57BL/6 mice were immunized with rAdASP2+rAdTS (rAdVax using a homologous prime/boost protocol before challenge with the Colombian strain. For therapeutic vaccination, rAdVax administration was initiated at 120 days post-infection (dpi, when mice were afflicted by CCC. Mice were analyzed for electrical abnormalities, immune response and cardiac parasitism and tissue damage. Prophylactic immunization with rAdVax induced antibodies and H-2Kb-restricted cytotoxic and interferon (IFNγ-producing CD8+ T-cells, reduced acute heart parasitism and electrical abnormalities in the chronic phase. Therapeutic vaccination increased survival and reduced electrical abnormalities after the prime (analysis at 160 dpi and the boost (analysis at 180 and 230 dpi. Post-therapy mice exhibited less heart injury and electrical abnormalities compared with pre-therapy mice. rAdVax therapeutic vaccination preserved specific IFNγ-mediated immunity but reduced the response to polyclonal stimuli (anti-CD3 plus anti-CD28, CD107a+ CD8+ T-cell frequency and plasma nitric oxide (NO levels. Moreover, therapeutic rAdVax reshaped immunity in the heart tissue as reduced the number of perforin+ cells

    Full Text Available Chronic paronychia is an inflammatory disorder of the nail folds of a toe or finger presenting as redness, tenderness, and swelling. It is recalcitrant dermatoses seen commonly in housewives and housemaids. It is a multifactorial inflammatory reaction of the proximal nail fold to irritants and allergens. Repeated bouts of inflammation lead to fibrosis of proximal nail fold with poor generation of cuticle, which in turn exposes the nail further to irritants and allergens. Thus, general preventive measures form cornerstone of the therapy. Though previously anti-fungals were the mainstay of therapy, topical steroid creams have been found to be more effective in the treatment of chronic paronychia. In recalcitrant cases, surgical treatment may be resorted to, which includes en bloc excision of the proximal nail fold or an eponychial marsupialization, with or without nail plate removal. Newer therapies and surgical modalities are being employed in the management of chronic paronychia. In this overview, we review recent epidemiological studies, present current thinking on the pathophysiology leading to chronic paronychia, discuss the challenges chronic paronychia presents, and recommend a commonsense approach to management.

    Full Text Available Chronic Daily Headache is a descriptive term that includes disorders with headaches on more days than not and affects 4% of the general population. The condition has a debilitating effect on individuals and society through direct cost to healthcare and indirectly to the economy in general. To successfully manage chronic daily headache syndromes it is important to exclude secondary causes with comprehensive history and relevant investigations; identify risk factors that predict its development and recognise its sub-types to appropriately manage the condition. Chronic migraine, chronic tension-type headache, new daily persistent headache and medication overuse headache accounts for the vast majority of chronic daily headaches. The scope of this article is to review the primary headache disorders. Secondary headaches are not discussed except medication overuse headache that often accompanies primary headache disorders. The article critically reviews the literature on the current understanding of daily headache disorders focusing in particular on recent developments in the treatment of frequent headaches.

    Chronic urticaria is an umbrella term, which encompasses physical urticarias, chronic "idiopathic" urticaria and urticarial vasculitis. It is important to recognize patients with physical urticarias as the investigation and treatment differs in important ways from patients with idiopathic chronic urticaria or urticarial vasculitis. Although relatively uncommon, urticarial vasculitis is an important diagnosis to make and requires histological confirmation by biopsy. Underlying systemic disease and systemic involvement, especially of the kidneys, should be sought. It is now recognized that chronic "idiopathic" urticaria includes a subset with an autoimmune basis caused by circulating autoantibodies against the high affinity IgE receptor (FceR1) and less commonly against IgE. Although the autologous serum skin test has been proven useful in prompting search for and characterization of circulating wheal-producing factors in chronic urticaria, its specificity as a screening test for presence of functional anti-FceR1 is low, and confirmation by demonstration of histamine-releasing activity in the patient's serum must be the benchmark test in establishing this diagnosis. Improved screening tests are being sought; for example, ability of the chronic urticaria patient's serum to evoke expression of CD 203c on donor human basophils is showing some promise. The strong association between autoimmune thyroid disease and autoimmune urticaria is also an area of ongoing research. Drug treatment continues to be centered on the H1 antihistamines, and the newer second-generation compounds appear to be safe and effective even in off-label dosage. Use of systemic steroids should be confined to special circumstances such as tapering regimens for acute flare-ups. Use of leukotriene antagonists is becoming popular, but the evidence for efficacy is conflicting. Cyclosporin is also effective and can be used in selected cases of autoimmune urticaria, and it is also effective in non

    A detailed description is given of the complex pathological picture observed in the case of a worker with 30 years' occupational exposure to lead in an accumulator factory (evolution of the disease, clinical findings, autopsy). In spite of a typical clinical picture, lead is not held responsible for the terminal encephalopathy, in view of the fact that Alzheimer's syndrome was discovered at autopsy. However, the neurovegetative asthenia and progressive kidney disease without hypertonia, but with uraemia, which preceded the encephalopathy are in all probability due to chronic lead poisoning. The article discusses the diagnosis and symptomatology of chronic lead poisoning, encephalopathy and kidney disease.

    Chronic unilateral vestibular loss is a condition defined by the presence of reduced function of the peripheral vestibular system on one side, which has generally persisted for 3 or more months. The deficit is demonstrated by a reduction of the vestibular-ocular reflex either at the bedside or on laboratory testing. Though some patients with chronic vestibular loss have disabling symptoms, others are asymptomatic. Causes include a viral/postviral disorder, Menière's disease, structural lesions, ischemia, and trauma. Any other systemic or genetic disorder would be expected to involve both sides at some point.

    Most angioedemas are histaminergic and correspond to deep urticarial swelling. Recurrent histaminergic angioedema led to the diagnosis of chronic urticaria, even when there are no superficial associated hives. Chronic urticaria is a benign disease, and autoimmune in 40 % of cases. The occurrence of angioedema in chronic urticaria is not a sign of severity. The occurrence of angioedema in chronic urticaria is associated with a longer duration of urticarial disease. NSAIDs and/or systemic corticotherapy are classic triggers of angioedema in chronic urticaria. In the absence of clinical endpoints, there is no need to make further assessment in chronic urticaria good responders to antihistamines.

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    International Nuclear Information System (INIS)

    Fourteen patients with prior trauma and/or surgery of the lower extremity and suspected active chronic osteomyelitis underwent MR imaging. Eleven patients also underwent In-111 scanning. All patients had surgical confirmation, MR imaging could assess the extent of abnormal marrow and distinguish abnormal marrow due to granulation tissue from active osteomyelitis. The presence and extent of soft-tissue infection could be determined and distinguished from bone involvement in spite of tissue distortion. The course and origin of sinus tracts could be followed. MR imaging was more sensitive to active infection than In-111 scanning. All 11 cases of active osteomyelitis were correctly diagnosed with MR imaging. In-111 scans were positive in only five of the eight cases of active infection in which scans were obtained. MR imaging is useful in chronic complicated osteomyelitis

    International Nuclear Information System (INIS)

    A long-lasting immunological suppression action seems to be produced by total lymphoid irradiation; some authors emphasize the favorable effect of this treatment on chronic progressive multiple sclerosis. In order to evaluate the actual role of TLI, 6 patients affected with chronic progressive multiple sclerosis were submitted to TLI with shaped and personalized fields at the Istituto del Radio, University of Brescia, Italy. The total dose delivered was 19.8 Gy in 4 weeks, 1.8 Gy/day, 5d/w; a week elapsed between the first and the second irradiation course. Disability according to Kurtzke scale was evaluated, together with blood lymphocyte count and irradiation side-effects, over a mean follow-up period of 20.8 months (range: 13-24). Our findings indicate that: a) disease progression was not markedly reduced by TLI; b) steroid hormones responsivity was restored after irradiation, and c) side-effects were mild and tolerable

    2010-06-01

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a demyelinating chronic neuropathy of immune origin whose diagnosis is based upon clinical, biological and electrophysiological data; previously critical to the diagnosis the nerve biopsy is now restricted to the rare situations where accurate diagnosis cannot be reached using these data alone. CIDP are mainly idiopathic, but a few associated diseases must be sought for as they require specific attention. Such associated diseases must particularly be discussed when the manifestations are severe or resistant to immunomodulating or immunosuppressive agents. Indeed, idiopathic CIDP are usually responsive to these treatments. The effectiveness of these treatments is limited by the importance of the secondary axonal loss. The dependence or the resistance may sometimes justify the association of several immunomodulating treatments. A single randomized controlled trial support the use of cytotoxic drugs and none with rituximab.

    Full Text Available Introduction. Chronic necrotizing pulmonary aspergillosis (CNPA is a cavitary, infectious process of lung parenchyma with slow progressive course. Vascular invasion and dissemination to other organs are unusual. Case report. We presented a 25-year old man with bilineal acute leukaemia who developed pulmonary and systemic symptoms. Chest CT showed nodular consolidations and cavitary lesions in both lungs. Bronchial biopsy revealed necrotic hyphae but it was negative for Aspergillus by culture. Serum was positive for antibodies to Aspergillus, but it was negative for antigens. A thoracoscopic lung biopsy of the upper left lobe revealed necrosis of lung tissue, with acute and chronic inflammation of the cavity wall and the presence of hyphae consistent with Aspergillus species. Conclusion. Although confirmation of the diagnosis is difficult, a combination of characteristic clinical, radiological and histological findings and either serological results positive for Aspergillus or the isolation of Aspergillus from respiratory samples are highly indicative of CNPA.

    Full Text Available Abstract Background To validate the Argentinean Spanish version of the PedsQL™ 4.0 Generic Core Scales in Argentinean children and adolescents with chronic conditions and to assess the impact of socio-demographic characteristics on the instrument's comprehensibility and acceptability. Reliability, and known-groups, and convergent validity were tested. Methods Consecutive sample of 287 children with chronic conditions and 105 healthy children, ages 2–18, and their parents. Chronically ill children were: (1 attending outpatient clinics and (2 had one of the following diagnoses: stem cell transplant, chronic obstructive pulmonary disease, HIV/AIDS, cancer, end stage renal disease, complex congenital cardiopathy. Patients and adult proxies completed the PedsQL™ 4.0 and an overall health status assessment. Physicians were asked to rate degree of health status impairment. Results The PedsQL™ 4.0 was feasible (only 9 children, all 5 to 7 year-olds, could not complete the instrument, easy to administer, completed without, or with minimal, help by most children and parents, and required a brief administration time (average 5–6 minutes. People living below the poverty line and/or low literacy needed more help to complete the instrument. Cronbach Alpha's internal consistency values for the total and subscale scores exceeded 0.70 for self-reports of children over 8 years-old and parent-reports of children over 5 years of age. Reliability of proxy-reports of 2–4 year-olds was low but improved when school items were excluded. Internal consistency for 5–7 year-olds was low (α range = 0.28–0.76. Construct validity was good. Child self-report and parent proxy-report PedsQL™ 4.0 scores were moderately but significantly correlated (ρ = 0.39, p Conclusion Results suggest that the Argentinean Spanish PedsQL™ 4.0 is suitable for research purposes in the public health setting for children over 8 years old and parents of children over 5 years old

    2015-01-01

    Chronic obstructive pulmonary disease (COPD) is a common disease with high global morbidity and mortality. COPD is characterized by poorly reversible airway obstruction, which is confirmed by spirometry, and includes obstruction of the small airways (chronic obstructive bronchiolitis) and emphysema, which lead to air trapping and shortness of breath in response to physical exertion. The most common risk factor for the development of COPD is cigarette smoking, but other environmental factors, such as exposure to indoor air pollutants - especially in developing countries - might influence COPD risk. Not all smokers develop COPD and the reasons for disease susceptibility in these individuals have not been fully elucidated. Although the mechanisms underlying COPD remain poorly understood, the disease is associated with chronic inflammation that is usually corticosteroid resistant. In addition, COPD involves accelerated ageing of the lungs and an abnormal repair mechanism that might be driven by oxidative stress. Acute exacerbations, which are mainly triggered by viral or bacterial infections, are important as they are linked to a poor prognosis. The mainstay of the management of stable disease is the use of inhaled long-acting bronchodilators, whereas corticosteroids are beneficial primarily in patients who have coexisting features of asthma, such as eosinophilic inflammation and more reversibility of airway obstruction. Apart from smoking cessation, no treatments reduce disease progression. More research is needed to better understand disease mechanisms and to develop new treatments that reduce disease activity and progression. PMID:27189863

  4. Imaging of chronic osteomyelitis

    International Nuclear Information System (INIS)

    The diagnosis of chronic osteomyelitis is made on the basis of clinical, radiologic and histologic findings. The role of imaging in patients with known chronic osteomyelitis is to detect and to delineate areas of active infection. To correctly interpret the imaging findings, it is essential to take both the individual clinical findings and previous imaging studies into account. Reliable signs of active infection are bone marrow abscess, sequestra and sinus tract formation. Only the combined evaluation of bony changes together with alterations of the adjacent soft tissues provides good diagnostic accuracy. Projection radiography gives an overview of the condition of the bone, which provides the basis for follow-up and the selection of further imaging modalities. Computed tomography can be used to evaluate even discrete or complex bony alterations and to guide percutaneous biopsy or drainage. Magnetic resonance imaging achieves the best diagnostic sensitivity and specificity and provides superior contrast as well as anatomical resolution in both bone marrow and soft tissues. In this paper the features and clinical relevance of imaging in primary chronic osteomyelitis, posttraumatic osteomyelitis, tuberculous spondylitis and osteomyelitis of the diabetic foot are reviewed, with particular respect to MRI.

    Symptomatic arsenic poisoning is not often seen in occupational exposure settings. Attempted homicide and deliberate long-term poisoning have resulted in chronic toxicity. Skin pigmentation changes, palmar and plantar hyperkeratoses, gastrointestinal symptoms, anemia, and liver disease are common. Noncirrhotic portal hypertension with bleeding esophageal varices, splenomegaly, and hypersplenism may occur. A metallic taste, gastrointestinal disturbances, and Mee's lines may be seen. Bone marrow depression is common. 'Blackfoot disease' has been associated with arsenic-contaminated drinking water in Taiwan; Raynaud's phenomenon and acrocyanosis also may occur. Large numbers of persons in areas of India, Pakistan, and several other countries have been chronically poisoned from naturally occurring arsenic in ground water. Toxic delirium and encephalopathy can be present. CCA-treated wood (chromated copper arsenate) is not a health risk unless burned in fireplaces or woodstoves. Peripheral neuropathy may also occur. Workplace exposure or chronic ingestion of arsenic-contaminated water or arsenical medications is associated with development of skin, lung, and other cancers. Treatment may incklude the use of chelating agents such as dimercaprol (BAL), dimercaptosuccinic acid (DMSA), and dimercaptopanesulfonic acid (DMPS).

    Trephination or trepanation is an intentional surgical procedure performed from the Stone Age. It looks like escaping a black evil from the head. This technique is still used for treatment of chronic subdural hematoma (SDH). Now, we know the origin, pathogenesis and natural history of this lesion. The author try to explore the history of trephination and modern discovery of chronic SDH. The author performed a detailed electronic search of PubMed. By the key word of chronic SDH, 2,593 articles were found without language restriction in May 2015. The author reviewed the fact and way, discovering the present knowledge on the chronic SDH. The first authentic report of chronic SDH was that of Wepfer in 1657. Chronic SDH was regarded as a stroke in 17th century. It was changed as an inflammatory disease in 19th century by Virchow, and became a traumatic lesion in 20th century. However, trauma is not necessary in many cases of chronic SDHs. The more important prerequisite is sufficient potential subdural space, degeneration of the brain. Modifying Virchow's description, chronic SDH is sometimes traumatic, but most often caused by severe degeneration of the brain. From Wepfer's first description, nearly 350 years passed to explore the origin, pathogenesis, and fate of chronic SDH. The nature of the black evil in the head of the Stone Age is uncovering by many authors riding the giant's shoulder. Chronic SDH should be categorized as a degenerative lesion instead of a traumatic lesion. PMID:27169062

    Comprehensive analysis of chronic radiation syndrome, covering epidemiology, pathogenesis, pathoanatomy, diagnosis and treatment. Based on observations in a unique sample of exposed residents of the Techa riverside villages in the Urals. Casts new light on the condition. Of value for all practitioners and researchers with an interest in chronic radiation syndrome. This book covers all aspects of chronic radiation syndrome (CRS) based on observations in a unique sample of residents of the Techa riverside villages in the southern Urals who were exposed to radioactive contamination in the 1950s owing to releases of liquid radioactive wastes from Mayak Production Association, which produced plutonium for weapons. In total, 940 cases of CRS were diagnosed in this population and these patients were subjected to detailed analysis. The opening chapters address the definition and classification of CRS, epidemiology and pathogenesis, covering molecular and cellular mechanisms, radioadaptation, and the role of tissue reactions. The pathoanatomy of CRS during the development and recovery stages is discussed for all organ systems. Clinical manifestations of CRS at the different stages are then described in detail and the dynamics of hematopoietic changes are thoroughly examined. In the following chapters, principles of diagnosis (including assessment of the exposure doses to critical organs) and differential diagnosis from a wide range of other conditions are discussed and current and potential treatment options, described. The medical and social rehabilitation of persons with CRS is also covered. This book, which casts new light on the condition, will be of value for all practitioners and researchers with an interest in CRS.

  11. Pathogenesis of chronic urticaria.

    2009-06-01

    Chronic urticaria is defined as the presence of urticaria (hives) for at least 6 weeks with the assumption that it occurs daily or close to it. If we eliminate physical urticarias and urticarial vasculitis from consideration, the remainder can be divided into autoimmune chronic urticaria (45%) and idiopathic chronic urticaria (55%). The autoimmune subgroup is associated with the IgG anti-IgE receptor alpha subunit in 35-40% of patients and IgG anti-IgE in an additional 5-10%. These autoantibodies have been shown to activate blood basophils and cutaneous mast cells in vitro with augmentation of basophil activation by complement and release of C5a, in particular. Binding methods (immunoblot and ELISA) yield positives in many autoimmune diseases as well as occasional normal subjects or patients with other forms of urticaria but most such sera are non-functional. Activation of basophils or mast cells causing histamine release is quite specific for chronic urticaria and defines the autoimmune subgroup. Although pathogenicity is not formally proven, the antibodies cause wealing upon intradermal injection, and removal of the autoantibody leads to remission. A cellular infiltrate is seen to be characterized by mast cell degranulation and infiltration of CD4+ T lymphocytes, monocytes, neutrophils, eosinophils, and basophils. The intensity of the infiltrate and clinical severity of the disease (including accompanying angio-oedema) is more severe in the autoimmune subpopulation. This latter group also has a higher evidence of human leucocyte antigen DR alleles associated with autoimmunity and a 25% incidence of antithyroid antibodies with diagnosed hypothyroidism in some. Hypo-responsiveness of patients' basophils to anti-IgE and hyperresponsiveness to serum defines another subpopulation (at least 50%) that overlaps the idiopathic and autoimmune subgroups. Hypo-responsiveness to anti-IgE has been shown to be associated with elevated levels of cytoplasmic phosphatases that

    Sexual function is often affected in individuals living with chronic illness and their partners, and multiple comorbidities increase the likelihood of sexual dysfunction. This review focuses on the areas of cardiovascular disease, respiratory conditions, and cancer, all areas for which there are practical, evidence-based strategies to guide sexual counseling. Although nurses have been reluctant to address the topic of sexuality in practice, a growing number of studies suggest that patients want nurses to address their concerns and provide resources to them. Thus, nurses must be proactive in initiating conversations on sexual issues to fill this gap in practice. PMID:24066783

    Chronic nonbacterial osteomyelitis is an autoinflammatory disease occurring mainly in children and adolescents, typically involving recurrent or persistent osteitic foci. The symptom is bone pain, possibly accompanied by soft tissue tenderness. Some patients exhibit symptoms of systemic inflammation. The. precise etiology of the disease is not known, but an imbalance of inflammatory and anti-inflammatory cytokines is presumed to play a role in the development of the disease. While an anti-inflammatory analgesic is in most cases sufficient to calm down the osteitis, the use of corticosteroids, anti- TNF-a inhibitors or bisphosphonates is required in some cases.

  3. Idiopathic chronic eosinophilic pneumonia

    2006-04-01

    Full Text Available Abstract Idiopathic chronic eosinophilic pneumonia (ICEP is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than lymphocyte counts in the bronchoalveolar lavage. ICEP is a rare disorder of unknown cause. Its exact prevalence remains unknown. ICEP may affect every age group but is rare in childhood. It is twice as frequent in women as in men. One third to one half of the ICEP patients have a history of asthma. The mainstay of treatment of ICEP is systemic corticosteroids. Response to oral corticosteroid therapy is dramatic and has led to the consideration of corticosteroid challenge as a diagnostic test for ICEP. Nevertheless, relapses or development of severe asthma are frequent when tapering or withdrawing treatment. Long-term oral corticosteroid therapy is necessary in up to half of the patients.

  4. The chronic leukaemias

    Directory of Open Access Journals (Sweden)

    Peter Jacobs

    1989-09-01

    Full Text Available The slow progression of both chronic granulocytic and lymphocytic leukaemia, when compared to their acute counterparts, has been used as an argument to support less aggressive therapy or even, in some instances, a watch-and-wait policy. This conservative approach is bolstered by a number of observations including the ease with which haematologic control can initially be achieved, the older age of patients with the lymphocytic variant and the paucity of controlled data showing that long disease-free survival or cure can result from the use of aggressive treatment. Given these circumstances, it is not surprising that many such individuals are managed outside specialised centres using a variety of agents and schedules, both of which may, on occasions, be inappropriate. Accumulating evidence suggests a need to reconsider these practices since cure is now possible in selected patients with chronic granulocytic leukaemia while the use of multi-drug regimens in the lymphatic form can significantly improve survival. These advances are the result of carefully conducted clinical trials involving many individuals the world over and constitute the basis fo r advocating early referral to those institutions where all the necessary expertise is available.

  5. Chronic Hepatitis C.

    2001-12-01

    Infection with hepatitis C virus (HCV) accounts for 40% of cases of chronic liver disease in the United States and is now the most common indication for liver transplantation. Estimates suggest that 4 million people (1.8%) of the American population are or have been infected with HCV. Currently, the treatment of choice for patients with chronic HCV infection is recombinant interferon alfa with ribavirin. Pegylated interferons are a promising new development, and in combination with ribavirin, they will rapidly become the standard of care. The goals of therapy are to slow disease progression, improve hepatic histology, reduce infectivity, and reduce the risk of hepatocellular carcinoma. Sustained virologic response, which generally implies the absence of viremia for 6 months or more following completion of therapy, is increasingly being regarded as a cure, with evidence of slowing or even regression of fibrosis on follow-up liver biopsy. A number of factors have been shown to be predictive of a sustained response, including viral genotype other than 1, low serum HCV RNA levels, absence of cirrhosis, younger age, female gender, and shorter duration of infection. Disease severity as assessed by liver biopsy, comorbidities, and possible contraindications to therapy should be weighed in the decision to begin treatment. Counseling patients regarding transmission, natural history, and drug and alcohol abstinence also should be included in management. Close monitoring should be done during treatment for side effects of interferon, including depression and bone marrow suppression. Hemolytic anemia is the major side effect of ribavirin.

  7. Clinical Scenarios in Chronic Kidney Disease: Chronic Tubulointerstitial Diseases.

    Meola, Mario; Samoni, Sara; Petrucci, Ilaria

    2016-01-01

    Chronic tubulointerstitial diseases are a common final pathway toward chronic renal failure regardless the primary damage (glomerular, vascular or directly the tubulointerstitium). Chronic tubulointerstitial nephritis (CTN) is characterized by interstitial scarring, fibrosis and tubule atrophy, resulting in progressive chronic kidney disease. Most frequent causes of CTN are drugs, heavy metals, obstructive uropathy, nephrolithiasis, reflux disease, immunologic diseases, neoplasia, ischemia, metabolic diseases, genetics and miscellaneous. At ultrasound (US), kidneys' morphological aspect is similar in all forms of chronic interstitial nephropathy and only chronic pyelonephritis with or without reflux shows distinguishing characteristics. In interstitial nephropathy, kidneys' profiles are finely irregular and corticomedullary differentiation is altered because of a diffused hyperechogenicity. The only indirect sign of chronic interstitial damage can be derived from the value of intrarenal resistive indexes that hardly overcome 0.75. US is mandatory in clinical chronic pyelonephritis work-up because it provides information on kidney's diameter and on growth nomogram in children. Renal profiles can be more or less altered depending on the number of cortical scars and the presence of pseudonodular areas of segmental compensatory hypertrophy. In the early stages, US diagnosis of renal tuberculosis is difficult because parenchymal lesions are non-specific. US sensitivity in the diagnosis of hydronephrosis is very high, close to 100% and, finally, US is the first choice imaging technique in the diagnosis of urinary lithiasis. PMID:27169608

  9. Folate Deficiency in Chronic Pancreatitis

    2010-07-01

    Full Text Available Dear Sir, While there has been a spurt of interest in genetic alterations associated with pancreatitis in the past few years, interest in the role of environmental factors has largely focused on alcoholism and smoking with insufficient attention being paid to the contributions of nutritional deficiency, and the role of environmental toxins in the pathogenesis of pancreatitis. Braganza and Dormandy [1] argue convincingly about the role played by cytochrome P450 monooxygenases (especially CYP1A enzyme induction by xenobiotics and the resultant oxidative stress, as also the now increasingly recognized reductive stress posed by the metabolites in initiating pancreatic injury. Their article underlines the important part played by the deficiency of methyl and thiol molecules in different stages of the progression of pancreatic damage. Furthermore, they attempt to establish a link between environmental and genetic factors and bring in a holistic view on the etiopathogenesis of chronic pancreatitis. We have recently demonstrated lower plasma methionine levels in two cohorts of chronic pancreatitis patients; one of tropical chronic pancreatitis and the other, of alcoholic chronic pancreatitis as compared to healthy controls [2] which suggests that deficiency of methyl groups may be a factor in various forms of pancreatitis. Similarly, we have shown lower red cell glutathione levels in chronic pancreatitis patients with tropical chronic pancreatitis and alcoholic chronic pancreatitis, indicating deficiency of thiol molecules. In addition, we have demonstrated significantly higher levels of plasma total homocysteine in chronic pancreatitis patients than in healthy controls. Moreover, our study has shown that there is a deficiency of red cell folate in the majority of chronic pancreatitis patients, more so in tropical chronic pancreatitis; and that folate deficiency appeared to be the key factor in hyperhomocysteinemia in chronic pancreatitis patients

    The process of chronic hypophosphatemic vitamine D-resistant rickets is described by observation of two cases. With the male patient - our first case - the disease was sporadic and had not been recognized for a long time. In his early adulthood it manifested itself as Umbauzonen (pseudofractures) in the larger context of active osteomalacia. It was possible to observe the pseudofractures before and while the patient was medicamentously treated. High doses of vitamine D 3 and dosage of phosphate mitigated the complaints although with respect to the radiological, scintigraphical, humoral and histological findings there was only slow improvement or no improvement at all. The patient's daughter is affected by the disease as well. In her case the pathological signs of her bones became better when treated with vitamine D 3.

    1997-11-15

    Rheumatoid arthritis (RA) is a chronic autoimmune disease involving progressive destruction of multiple joints and, in the later stages, significant mortality. Worldwide, 1% of the population is afflicted. Despite new insights into the autoimmune mechanisms during the last decade a cure has not been found, although pain, disability and general suffering can be alleviated via several therapeutic approaches when carefully coordinated. Early use of immunosuppressive therapy with DMARDs (disease modifying antirheumatic drugs), while avoiding their side effects, is critical for disease control. Counselling within a good doctor-patient relationship, with the additional help of physiotherapy and ergotherapy, increases the patient's capacity to cope with the disease. Hand and joint surgery, skillfully performed, decreases pain and disability. Newer strategies of immunosuppression, while encouragingly effective, are only short term. These experimental agents are more expensive, they are associated with side effects and their future place in RA therapy has yet to be defined. PMID:9454312

    Chronic cough is one of the most common reasons for referral to a respiratory physician. Although fatal complications are rare, it may cause considerable distress in the patient’s daily life. Western and local data shows that in patients with a normal chest radiograph, the most common causes are postnasal drip syndrome, postinfectious cough, gastro-oesophageal reflux disease and cough variant asthma. Less common causes are the use of angiotensin-converting enzyme inhibitors, smoker’s cough and nonasthmatic eosinophilic bronchitis. A detailed history-taking and physical examination will provide a diagnosis in most patients, even at the primary care level. Some cases may need further investigations or specialist referral for diagnosis. PMID:26892615

  18. 'Chronic' identities in mental illness.

    von Peter, Sebastian

    2013-04-01

    The term 'chronicity' is still widely used in psychiatric discourse and practice. A category employed in political, administrative and therapeutic contexts, it guides practitioners' beliefs and actions. This paper attempts a review of the attitudes and procedures that result as a consequence of identifying 'chronically' disturbed identities in clinical practice. An essentially social, relational and materialist understanding of mental illness is used to highlight the kind of thinking underlying the notion of 'chronic' identities in day-to-day psychiatric routines. Problematising the notions of singularity and expressiveness, as well as mind/body- and self/other-distinctions, it claims the category itself is responsible for creating a 'chronic' kind of being. A spatial metaphor is presented in the conclusion, illustrating a mental strategy by which we can re-shape our thinking about 'chronic' identities. It attempts to describe how the shift from an epistemological to a praxeographic approach could build a more complete understanding of mental illness. PMID:23528064

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    The infection from Epstein-Barr virus (EBV or virus of infectious mononucleosis, together with other herpesviruses’ infections, represents a prototype of persistent viral infections characterized by the property of the latency. Although the reactivations of the latent infection are associated with the resumption of the viral replication and eventually with the “shedding”, it is still not clear if this virus can determine chronic infectious diseases, more or less evolutive. These diseases could include some pathological conditions actually defined as “idiopathic”and characterized by the “viral persistence” as the more credible pathogenetic factor. Among the so-called idiopathic syndromes, the “chronic fatigue syndrome” (CFS aroused a great interest around the eighties of the last century when, just for its relationship with EBV, it was called “chronic mononucleosis” or “chronic EBV infection”.

    Today CFS, as defined in 1994 by the CDC of Atlanta (USA, really represents a multifactorial syndrome characterized by a chronic course, where reactivation and remission phases

    INTRODUCTION. Patients with chronic migraine often report lower cognitive performance, which affects their quality of life. AIMS. To analyse whether the mnemonic capacity of patients with chronic migraine is altered or not. SUBJECTS AND METHODS. A cross-sectional study was conducted in patients with chronic migraine evaluated consecutively in our unit, and paired by age (18-60 years) and gender with a control group consisting of cognitively healthy volunteers. The following cognitive instruments were administered: Folstein Minimental State Examination (MMSE), Memory Alteration Test (M@T), Montreal Cognitive Assessment (MoCA) and working memory. RESULTS. A total of 30 patients with chronic migraine were included (mean age: 49.33 ± 10.05 years) paired with a control group of 30 healthy volunteers (mean age: 44.83 ± 10.91 years). The mean elapsed time since onset of the patients with chronic migraine was 4.47 ± 2.74 years. On performing a comparative analysis between the two groups, significant differences were found with overall lower scores in the group of patients with chronic migraine in the MoCA (24.16 versus 29), M@T (43.76 versus 48.8) and working memory tests (17.5 versus 24.26). Performance in the MMSE was similar in both groups. CONCLUSIONS. Patients with chronic migraine can have lower cognitive performance regardless of distracting elements, such as pharmacological factors or psychiatric comorbidity, since chronic migraine can be understood as yet another element within the spectrum of chronic pain.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the leading causes of severe pulmonary hypertension. According to previously reported studies in the pertinent literature, chronic inflammatory conditions may be implicated in the development of CTEPH. We herein describe the case of a 56-year-old woman who was diagnosed with CTEPH in association with chronic infection. The patient had experienced five episodes of pneumonia in the five years prior to the diagnosis of CTEPH. Blood tests from the previous five years of outpatient follow-up demonstrated that the C-reactive protein level was slightly elevated. This case suggests that a relationship exists between chronic inflammation and CTEPH, and furthermore, may contribute towards elucidating the pathophysiology of CTEPH. PMID:27250055

    Chronic paronychia is a common occupational disease. It is multifactorial and affects a number of different groups of workers. However, the condition is not described as affecting hairdressers although hairdressing is associated with a range of other occupation-related hand conditions. We report an unusual case of chronic paronychia in a female hairdresser which occurred as a consequence of a hair shaft penetrating beneath the nail fold. Personal hygiene with thorough removal of any hairs that have penetrated the epidermis and wearing clean gloves can prevent the condition. We suggest that clinicians should be aware of the types of occupation and mechanisms involved in patients developing chronic paronychia. PMID:24985481

    Seventy-nine patients with chronic lymphocytic leukaemia were evaluated for the presence of autoimmune diseases and autoantibodies. One patient has polymyositis and two additional patients presented with features suggestive of pernicious anaemia and chronic active hepatitis. The Coombs' direct test was positive in 7% and immune thrombocytopenia was present in 8.1% of patients. Five (7%) patients had M-protein in the serum. No increased frequency of other autoantibodies was noted in our study group. We conclude that the propensity to develop antibodies is restricted only to the haematopoietic system and that there is no increased frequency of non-haematological autoimmune diseases in chronic lymphatic leukaemia.

    Pain is frequent in communicative or no-communicative, ambulatory, institutionalized or hospitalized veterans. It is associated with severe comorbidity so much more than chronic pain could be neglected and expressed of atypical manner or masked by the absence of classical symptoms in particular in case of dementia or of sensory disorders. Pain detection by clinic examination or by pain assessment's methods and adequate approach by pharmacological and non pharmacological therapies are essential for correct pain management. On pharmacological plan, the strategy of the O.M.S. landings is applicable owing to a more particular attention to secondary effects and drugs interactions. AINS must be manipulated with prudence. There are no reasons to exclude opioides from the therapeutic arsenal but with a reduction of the starting doses, a regular adaptation and a very attentive survey. In drugs of landing 2, tramadol reveals itself as efficient and better tolerated as the codeine and dextropropoxyphene has to be to avoid. The obtaining of a satisfactory result depends on a regular assessment of the pain in a context of polydisciplinar approach (physicians, nurses, paramedicals, other care givers).

    Greenberger, Paul A

    2014-01-01

    Chronic urticaria is defined as episodic or daily hives lasting for at least 6 weeks and impairs quality of life. Two main subtypes include chronic idiopathic (spontaneous) urticaria and inducible (physical) urticaria, but some patients have urticarial vasculitis. "Autoimmune chronic urticaria" implies the presence of histamine releasing or mast cell activating autoantibodies to IgE or FcϵRI, the high affinity receptor on mast cells and basophils. In patients not readily controlled with labeled dosages of second generation H1 receptor antagonists (antihistamines), there is evidence for reduction of urticaria using up to 4 fold increases in labeled dosages. The biologic modifier, omalizumab, helps to reduce lesions of chronic urticaria within 1-2 weeks. PMID:25383135

    2014-02-01

    Chronic musculoskeletal pain results from a complex interplay of mechanical, biochemical, psychological, and social factors. Effective management is markedly different from that of acute musculoskeletal pain. Understanding the physiology of pain transmission, modulation, and perception is crucial for effective management. Pharmacologic and nonpharmacologic therapies such as psychotherapy and biofeedback exercises can be used to manage chronic pain. Evidence-based treatment recommendations have been made for chronic pain conditions frequently encountered by orthopaedic surgeons, including low back, osteoarthritic, posttraumatic, and neuropathic pain. Extended-release tramadol; select tricyclic antidepressants, serotonin reuptake inhibitors, and anticonvulsants; and topical medications such as lidocaine, diclofenac, and capsaicin are among the most effective treatments. However, drug efficacy varies significantly by indication. Orthopaedic surgeons should be familiar with the widely available safe and effective nonnarcotic options for chronic musculoskeletal pain.

    Hague, Matthew; Shenker, Nicholas

    2014-12-01

    Chronic pain is defined as an unpleasant sensory and emotional experience persisting longer than the normal process of healing, usually longer than 3 months. About a fifth of the world's population is believed to suffer from chronic pain. In Europe, chronic pain accounts for nearly 500 m lost working days, and it costs the European economy >€34 billion (£28 billion) every year. Establishing a reliable diagnosis is the primary challenge in evaluating a patient with chronic pain. Common diagnoses not to miss include seronegative spondyloarthritides, endocrine abnormalities including severe vitamin D deficiency and polymyalgia rheumatica. Once important or treatable diagnoses have been ruled out, the history can be used as a tool to establish a therapeutic plan for shared decision-making using the biopsychosocial model. Onward referral to pain clinics can be helpful for more involved patient management, but often good outcomes are achieved with the support of primary care. PMID:26096090

    Van den Bergh, Peter Y K; Rajabally, Yusuf A

    2013-06-01

    Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the most common autoimmune neuropathy. The diagnosis depends on the clinical presentation with a progressive or relapsing course over at least 2 months and electrophysiological evidence of primary demyelination. Whereas typical CIDP is quite easily recognizable because virtually no other neuropathies present with both distal and proximal motor and sensory deficit, atypical CIDP, focal and multifocal variants in particular, may represent a difficult diagnostic challenge. CIDP very likely is an underdiagnosed condition as suggested also by a positive correlation between prevalence rates and sensitivity of electrophysiological criteria. Since no 'gold standard' diagnostic marker exists, electrophysiological criteria have been optimized to be at the same time as sensitive and as specific as possible. Additional supportive laboratory features, such as increased spinal fluid protein, MRI abnormalities of nerve segments, and in selected cases nerve biopsy lead to the correct diagnosis in the large majority of the cases. Objective clinical improvement following immune therapy is also a useful parameter to confirm the diagnosis. The pathogenesis and pathophysiology of CIDP remain poorly understood, but the available evidence for an inflammatory origin is quite convincing. Steroids, intravenous immunoglobulin (IVIG), and plasma exchange (PE) have been proven to be effective treatments. IVIG usually leads to rapid improvement, which is useful in severely disabled patients. Repeat treatment over regular time intervals for many years is often necessary. The effect of steroids is slower and the side-effect profile may be problematic, but they may induce disease remission more frequently than IVIG. An important and as of yet uncompletely resolved issue is the evaluation of long-term outcome to determine whether the disease is still active and responsive to treatment.

  14. Immunopathology of chronic rhinosinusitis

    Directory of Open Access Journals (Sweden)

    Atsushi Kato

    2015-04-01

    Full Text Available Chronic rhinosinusitis (CRS is a heterogeneous disease characterized by local inflammation of the upper airways and sinuses which persists for at least 12 weeks. CRS can be divided into two phenotypes dependent on the presence of nasal polyps (NPs; CRS with NPs (CRSwNP and CRS without NPs (CRSsNP. Immunological patterns in the two diseases are known to be different. Inflammation in CRSsNP is rarely investigated and limited studies show that CRSsNP is characterized by type 1 inflammation. Inflammation in CRSwNP is well investigated and CRSwNP in Western countries shows type 2 inflammation and eosinophilia in NPs. In contrast, mixed inflammatory patterns are found in CRSwNP in Asia and the ratio of eosinophilic NPs and non-eosinophilic NPs is almost 50:50 in these countries. Inflammation in eosinophilic NPs is mainly controlled by type 2 cytokines, IL-5 and IL-13, which can be produced from several immune cells including Th2 cells, mast cells and group 2 innate lymphoid cells (ILC2s that are all elevated in eosinophilic NPs. IL-5 strongly induces eosinophilia. IL-13 activates macrophages, B cells and epithelial cells to induce recruitment of eosinophils and Th2 cells, IgE mediated reactions and remodeling. Epithelial derived cytokines, TSLP, IL-33 and IL-1 can directly and indirectly control type 2 cytokine production from these cells in eosinophilic NPs. Recent clinical trials showed the beneficial effect on eosinophilic NPs and/or asthma by monoclonal antibodies against IL-5, IL-4Rα, IgE and TSLP suggesting that they can be therapeutic targets for eosinophilic CRSwNP.

  15. Neurovascular Unit in Chronic Pain

    Beatrice Mihaela Radu

    2013-01-01

    Full Text Available Chronic pain is a debilitating condition with major socioeconomic impact, whose neurobiological basis is still not clear. An involvement of the neurovascular unit (NVU has been recently proposed. In particular, the blood-brain barrier (BBB and blood-spinal cord barrier (BSCB, two NVU key players, may be affected during the development of chronic pain; in particular, transient permeabilization of the barrier is suggested by several inflammatory- and nerve-injury-based pain models, and we argue that the clarification of molecular BBB/BSCB permeabilization events will shed new light in understanding chronic pain mechanisms. Possible biases in experiments supporting this theory and its translational potentials are discussed. Moving beyond an exclusive focus on the role of the endothelium, we propose that our understanding of the mechanisms subserving chronic pain will benefit from the extension of research efforts to the NVU as a whole. In this view, the available evidence on the interaction between analgesic drugs and the NVU is here reviewed. Chronic pain comorbidities, such as neuroinflammatory and neurodegenerative diseases, are also discussed in view of NVU changes, together with innovative pharmacological solutions targeting NVU components in chronic pain treatment.

    2016-09-01

    Urticaria is a relatively common condition that if chronic can persist for weeks, months or years and affect quality of life significantly. The etiology is often difficult to determine, especially as it becomes chronic. Many cases of chronic urticaria are thought to be autoimmune, although there is no consensus that testing for autoimmunity alters the diagnostic or management strategies or outcomes. Many times, urticaria is easily managed with antihistamines and/or short courses of oral corticosteroids, but too often control is insufficient and additional therapies must be added. For years, immune modulating medications, such as cyclosporine and Mycophenolate Mofetil, have been used in cases refractory to antihistamines and oral corticosteroids, although the evidence supporting their efficacy and safety has been limited. Omalizumab was recently approved for the treatment of chronic urticaria unresponsive to H1-antagonists. This IgG anti-IgE monoclonal antibody has been well demonstrated to safely and effectively control chronic urticaria at least partially in approximately 2/3 of cases. However, the mechanism of action and duration of treatment for omalizumab is still unclear. It is hoped that as the pathobiology of chronic urticaria becomes better defined, future therapies that target specific mechanistic pathways will be developed that continue to improve the management of these often challenging patients.

    2010-01-01

    Full Text Available Objective: Chronic hemodialysis affects various body systems, one of which is the respiratory system. Since respiration is the prime source for speech, vocal dysfunctions are expected to be present in patients with chronic hemodialysis. The present study attempts to shed light on the changes in acoustic and aerodynamic characteristics of voice, if any, in patients with chronic hemodialysis. Materials and Methods: Phonation of sustained vowel/a/sample was subjected to acoustic analysis using VAGHMI software. Sustained duration of/a/,/s/, and/z/ was recorded for the purpose of aerodynamic analysis. The independent t test was employed to find the significant difference between the two groups. Results: Chronic hemodialyzed subjects showed significant deviation in frequency, perturbation, and aerodynamic measures when compared to normal subjects. These results are discussed with respect to the underlying pathophysiology. Conclusion: The results of the present study revealed that subjects with chronic hemodialysis exhibit clinical evidence of voice disorders. Vocal deviations in chronic hemodialyzed subjects are explained due to the influence of the renal system on the respiratory and the phonatory system and the negative fluid balance effect of hemodialysis.

    2011-04-01

    Full Text Available Introduction: The chronic cough is sometimes manifested as an imprecise symptom, but of great importance for both the diagnosis and the prognosis. In an otorhinolaryngologic approach, several illnesses that can occur with it can be numbered, including 2 of the 3 main causes of chronic cough. Objective: To identify the main otorhinolaryngologic diseases showing the chronic cough as one of their manifestations. Method: A literature's revision was performed in several scientific articles, specialized books and consultation in Birene and Scielo databases. Literature's revision: cough production in the upper airways is usually associated with an inflammatory reaction by stimulating sensitive receptors of these areas or by mechanic stimulus. The main cause of the chronic cough in the otorhinolaryngology day-to-day is the post-nasal drip, gathering together by itself 02 of the most common diseases: rhinitis and sinusitis. Laryngitis as a result of gastroesophageal reflux (GER stands out in the index of chronic cough etiology, but it is not as severe as GER . Neoplasias are also somewhat frequent causes of cough, and the difficulty in diagnosing the cough cause is common in this disease group. Motility disorder, laryngeal irritation persistence, parasitic disease and injuries by inhalation of toxic products were also found as a cause of cough for longer than 03 months. Conclusion:Chronic cough is a frequent and important finding in otorhinolaryngology and cannot be underestimated, and a careful anamnesis is the best way to determine the etiology and perform a correct treatment for the patient's disease.

    Full Text Available This work compared the time at which negative seroconversion was detected by conventional serology (CS and by the ELISA-F29 test on a cohort of chronic chagasic patients treated with nifurtimox or benznidazole. A retrospective study was performed using preserved serum from 66 asymptomatic chagasic adults under clinical supervision, and bi-annual serological examinations over a mean follow-up of 23 years. Twenty nine patients received trypanocide treatment and 37 remained untreated. The ELISA-F29 test used a recombinant antigen which was obtained by expressing the Trypanosoma cruzi flagellar calcium-binding protein gene in Escherichia coli. Among the untreated patients, 36 maintained CS titers. One patient showed a doubtful serology in some check-ups. ELISA-F29 showed constant reactivity in 35 out of 37 patients and was negative for the patient with fluctuating CS. The treated patients were divided into three groups according to the CS titers: in 13 they became negative; in 12 they decreased and in four they remained unchanged. ELISA-F29 was negative for the first two groups. The time at which negativization was detected was significantly lower for the ELISA-F29 test than for CS, 14.5 ± 5.7 and 22 ± 4.9 years respectively. Negative seroconversion was observed in treated patients only. The results obtained confirm that the ELISA-F29 test is useful as an early indicator of negative seroconversion in treated chronic patients.Este trabalho comparou os tempos de soroconversão negativos obtidos pela sorologia convencional (CS e teste ELISA-F29 em uma coorte de pacientes chagásicos crônicos tratados com nifurtimox ou benznidazol.

    The basis for impaired left ventricular function of hearts in moderate to severe stages of hypertrophy and congestive heart failure remains uncertain. At the cellular level, the mechanisms governing the movements of calcium in the myocardium are actually depressed and might at least in part account for the slowing of the maximum shortening velocity and the impaired relaxation. These alterations of membrane proteins seem particularly important in species where the slowing of Vmax cannot be a consequence of the myosin heavy chain shift. They lead to an unstable equilibrium of calcium homeostasis and to calcium overload in heart failure. On the other hand, the enhanced density and remodeling of collagen in the hypertrophied heart, which would depend on elevation in circulating aldosterone, impair myocardial stiffness with diastolic dysfunction and lead to altered pumping capacity of the heart. Disturbances of calcium metabolism and matrix collagen remodeling enhance early afterdepolarizations and arrhythmias. PMID:1385839

  2. The Murine Model of Mucopolysaccharidosis IIIB Develops Cardiopathies over Time Leading to Heart Failure.

    Directory of Open Access Journals (Sweden)

    Gabriele Giacomo Schiattarella

    Full Text Available Mucopolysaccharidosis (MPS IIIB is a lysosomal disease due to the deficiency of the enzyme α-N-acetylglucosaminidase (NAGLU required for heparan sulfate (HS degradation. The disease is characterized by mild somatic features and severe neurological disorders. Very little is known on the cardiac dysfunctions in MPS IIIB. In this study, we used the murine model of MPS IIIB (NAGLU knockout mice, NAGLU(-/- in order to investigate the cardiac involvement in the disease. Echocardiographic analysis showed a marked increase in left ventricular (LV mass, reduced cardiac function and valvular defects in NAGLU(-/- mice as compared to wild-type (WT littermates. The NAGLU(-/- mice exhibited a significant increase in aortic and mitral annulus dimension with a progressive elongation and thickening of anterior mitral valve leaflet. A severe mitral regurgitation with reduction in mitral inflow E-wave-to-A-wave ratio was observed in 32-week-old NAGLU(-/- mice. Compared to WT mice, NAGLU(-/- mice exhibited a significantly lower survival with increased mortality observed in particular after 25 weeks of age. Histopathological analysis revealed a significant increase of myocardial fiber vacuolization, accumulation of HS in the myocardial vacuoles, recruitment of inflammatory cells and collagen deposition within the myocardium, and an increase of LV fibrosis in NAGLU(-/- mice compared to WT mice. Biochemical analysis of heart samples from affected mice showed increased expression levels of cardiac failure hallmarks such as calcium/calmodulin-dependent protein kinase II, connexin43, α-smooth muscle actin, α-actinin, atrial and brain natriuretic peptides, and myosin heavy polypeptide 7. Furthermore, heart samples from NAGLU(-/- mice showed enhanced expression of the lysosome-associated membrane protein-2 (LAMP2, and the autophagic markers Beclin1 and LC3 isoform II (LC3-II. Overall, our findings demonstrate that NAGLU(-/- mice develop heart disease, valvular abnormalities and cardiac failure associated with an impaired lysosomal autophagic flux.

    In recent years sterilization that can cause problems of the psyche and marital life has been recommended much less frequently with respect to chronic diseases. As regards heart and hypertensive diseases pregnancy is always contraindicated in case of 3rd and 4th disease categories and sterilization is recommended according to the New York Heart Association. As far as 1st and 2nd category patients are concerned if the load carrying capacity is normal pregnancy could be undertaken. Combination pills are not recommended for contraception because they can cause fluid retention or increase the risk of thrombosis. If the patient has a higher-than-normal risk of developing thrombosis or infection, for instance, those who wear pacemakers only tablets containing progesterone or subdermal capsule implants can be used. In those with blood pressure problems the additional use of the IUD is also advised. Among diseases of neurological and psychic origin the effect of hormonal contraceptives is weakened by antiepileptics, but even in such cases older combination pills of larger doses of active ingredients can be employed. Migraine is exacerbated in 1/3 of patients; here IUDs can be used. Even the contraceptive tablets themselves can induce depression. In psychosis methods requiring regular attention can be easily forgotten, therefore the IUD is the most suitable device. In diabetes progesterone and other progestogens reduce insulin response, harm carbohydrate metabolism; therefore in young people the IUD is preferred an in older women with children even sterilization can be employed. Hormonal tablets must not be used in hyperlipidemia and liver diseases. Caution must be exercised in hyperthyroidism and in endocrine disorders (e.g., Cushing's syndrome); if it is accompanied by blood pressure disorders appropriate treatment is required. In kidney diseases pregnancy is contraindicated if it is accompanied by blood pressure increase or a higher level of creatine. On the other hand

    Full Text Available We conducted a clinical and electromyographical study in patients with Chagas' disease in the indeterminate or chronic stages of the illness. Altogether 841 patients were examined. Only 511 were admitted within the protocol; the remainder patients were rejected because they showed other causes able to damage the nervous system. Fifty two (10.17% out of the 511 patients showed signs and symptoms of peripheral nervous system involvement in the form of sensory impairment and diminished tendon jerks suggesting the presence of neuropathy. Forty five of them were submitted to a conventional electromyographical examination. Fifteen of mem showed normal results, while the remainder 30 disclosed a reduced interference pattern, being most of the remaining motor unit potentials fragmented or poliphasic, reduced sensory and motor conduction velocities and diminished amplitude of the sensory action potential. The findings suggest that some chagasic patients in the indeterminate or chronic stages of the disease may develop a clinical mild sensory-motor peripheral neuropathy.El estúdio presente fue diseftado con ei objeto de pesquizar Ia existência de manifestaciones clinicas en pacientes afectados por enfermedad de Chagas, en estádio indeterminado o crônico, que tuviesen, ai menos, 2 reacciones serologicas positivas.

    1998-09-28

    The subjective symptom of "fatigue" is one of the most widespread in the general population and is a major source of healthcare utilization. Prolonged fatigue is often associated with neuropsychological and musculoskeletal symptoms that form the basis of several syndromal diagnoses including chronic fatigue syndrome, fibromyalgia, and neurasthenia, and is clearly not simply the result of a lack of force generation from the muscle. Current epidemiologic research in this area relies predominantly on self-report data to document the prevalence and associations of chronic fatigue. Of necessity, this subjective data source gives rise to uncertain diagnostic boundaries and consequent divergent epidemiologic, clinical, and pathophysiologic research findings. This review will highlight the impact of the case definition and ascertainment methods on the varying prevalence estimates of chronic fatigue syndrome and patterns of reported psychological comorbidty. It will also evaluate the evidence for a true postinfective fatigue syndrome.

    Periodontal disease has been associated with an increased risk of cardiovascular events. The purpose of our study was to investigate whether a correlation between periodontitis and chronic heart failure exists, as well as the nature of the underlying cause. We enrolled 71 patients (mean age, 54 ± 13 yr; 56 men) who had stable chronic heart failure; all underwent complete cardiologic and dental evaluations. The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P <0.00001). The severity of periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases.

  9. Pharmacologic Agents for Chronic Diarrhea.

    2015-10-01

    Chronic diarrhea is usually associated with a number of non-infectious causes. When definitive treatment is unavailable, symptomatic drug therapy is indicated. Pharmacologic agents for chronic diarrhea include loperamide, 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists, diosmectite, cholestyramine, probiotics, antispasmodics, rifaximin, and anti-inflammatory agents. Loperamide, a synthetic opiate agonist, decreases peristaltic activity and inhibits secretion, resulting in the reduction of fluid and electrolyte loss and an increase in stool consistency. Cholestyramine is a bile acid sequestrant that is generally considered as the first-line treatment for bile acid diarrhea. 5-HT3 receptor antagonists have significant benefits in patients with irritable bowel syndrome (IBS) with diarrhea. Ramosetron improves stool consistency as well as global IBS symptoms. Probiotics may have a role in the prevention of antibiotic-associated diarrhea. However, data on the role of probiotics in the treatment of chronic diarrhea are lacking. Diosmectite, an absorbent, can be used for the treatment of chronic functional diarrhea, radiation-induced diarrhea, and chemotherapy-induced diarrhea. Antispasmodics including alverine citrate, mebeverine, otilonium bromide, and pinaverium bromide are used for relieving diarrheal symptoms and abdominal pain. Rifaximin can be effective for chronic diarrhea associated with IBS and small intestinal bacterial overgrowth. Budesonide is effective in both lymphocytic colitis and collagenous colitis. The efficacy of mesalazine in microscopic colitis is weak or remains uncertain. Considering their mechanisms of action, these agents should be prescribed properly.

    Drug absorption in patients with chronic pancreatitis might be affected by the pathophysiology of the disease. The exocrine pancreatic insufficiency is associated with changes in gastrointestinal intraluminal pH, motility disorder, bacterial overgrowth and changed pancreatic gland secretion....... Together these factors can result in malabsorption and may also affect the efficacy of pharmacological intervention. The lifestyle of chronic pancreatitis patients may also contribute to gastrointestinal changes. Many patients limit their food intake because of the pain caused by eating and in some cases...... food intake is more or less substituted with alcohol, tobacco and coffee. Alcohol and drug interaction are known to influence the pharmacokinetics by altering either drug absorption or by affecting liver metabolism. Since patients suffering from chronic pancreatitis experience severe pain, opioids...

    Neurosurgical treatment of pain used two kind of techniques: 1) Lesional techniques interrupt the transmission of nociceptive neural input by lesionning the nociceptive pathways (drezotomy, cordotomy, tractotomy…). They are indicated to treat morphine-resistant cancer pain and few cases of selected neuropathic pain. 2) Neuromodulation techniques try to decrease pain by reinforcing inhibitory and/or to limit activatory mechanisms. Chronic electrical stimulation of the nervous system (peripheral nerve stimulation, spinal cord stimulation, motor cortex stimulation…) is used to treat chronic neuropathic pain. Intrathecal infusion of analgesics (morphine, ziconotide…), using implantable pumps, allows to increase their efficacy and to reduce their side effects. These techniques can improve, sometimes dramatically, selected patients with severe and chronic pain, refractory to all other treatments. The quality of the analgesic outcome depends on the relevance of the indications. PMID:25681114

    Background To validate the Argentinean Spanish version of the PedsQL™ 4.0 Generic Core Scales in Argentinean children and adolescents with chronic conditions and to assess the impact of socio-demographic characteristics on the instrument's comprehensibility and acceptability. Reliability, and known-groups, and convergent validity were tested. Methods Consecutive sample of 287 children with chronic conditions and 105 healthy children, ages 2–18, and their parents. Chronically ill children were: (1) attending outpatient clinics and (2) had one of the following diagnoses: stem cell transplant, chronic obstructive pulmonary disease, HIV/AIDS, cancer, end stage renal disease, complex congenital cardiopathy. Patients and adult proxies completed the PedsQL™ 4.0 and an overall health status assessment. Physicians were asked to rate degree of health status impairment. Results The PedsQL™ 4.0 was feasible (only 9 children, all 5 to 7 year-olds, could not complete the instrument), easy to administer, completed without, or with minimal, help by most children and parents, and required a brief administration time (average 5–6 minutes). People living below the poverty line and/or low literacy needed more help to complete the instrument. Cronbach Alpha's internal consistency values for the total and subscale scores exceeded 0.70 for self-reports of children over 8 years-old and parent-reports of children over 5 years of age. Reliability of proxy-reports of 2–4 year-olds was low but improved when school items were excluded. Internal consistency for 5–7 year-olds was low (α range = 0.28–0.76). Construct validity was good. Child self-report and parent proxy-report PedsQL™ 4.0 scores were moderately but significantly correlated (ρ = 0.39, p < 0.0001) and both significantly correlated with physician's assessment of health impairment and with child self-reported overall health status.

    The paper is concerned with the findings of multimodality roentgenofunctional diagnosis of chronic enterocolitis in 100 patients. A radiofunctional study was performed under the conditions of X-ray TV and videomagnetic recording of the stomach, duodenum and small intestine using barium swallow. Simultaneously the gall bladder and bile ducts condition was studied. All the patients underwent colon examination with the help of a contrast enema (primary double contrast examination) and 24 h after taking barium swallow and food. The study showed that changes in the small intestine in chronic enterocolitis were combined with a certain regularity of those in the stomach, duodenum, colon and gall bladder.

There have been many exciting developments in research studies of the pathophysiology and treatment of FM and related syndromes that have the potential to improve the recognition and management of patients with FM and other conditions with FM-like pain. However, much of the new information has not reached all clinicians, especially primary care clinicians, who have the greatest potential to use this new knowledge to positively impact their patients’ lives. Furthermore, there are persistent misconceptions about FM and a lack of consensus regarding the diagnosis and treatment of FM. This paper presents a framework for future global efforts to improve the understanding and treatment of FM and other associated chronic pain syndromes, disseminate research findings, identify ways to enhance advocacy for these patients, and improve global efforts to collaborate and reach consensus about key issues related to FM and chronic pain in general.

    Mucociliary clearance is an important defence mechanism of upper and lower respiratory tracts. Any disturbance in the mechanism leads to stagnation of secretions and secondary infection with prolonged mucociliary clearance time. The present study was undertaken to establish normal mucociliary clearance time in our region and to evaluate its diagnostic and prognostic potential in chronic sinusitis of variable duration with and without obstructive diseases.

    To gain at least an initial understanding of the underlying beliefs and attitudes in a cross-cultural situation, we believe that the three key points discussed in this paper should prove a significant point of departure: 1. Traditional beliefs about the cause of chronic illness or disability will play a significant role in determining family and community attitudes toward individuals with a disability and will influence when, how, and why medical input is sought. 2. The expectation of survival on the part of parents and community will have an effect on the amount of time, energy, and cooperation shown by family and community for the individual who has an impairment. 3. The expectations by family and community for the social role(s) and individual with a chronic illness or disability will hold will affect a broad range of issues, including education, social integration, and independence. Furthermore, although chronic illness and disability are often considered as issues distinct from the full range of problems encountered in society for immigrant and minority groups, in fact, these issues could not be more closely tied. The frequently discussed concerns within the ethnic and minority community about the role of the family, integration and acculturation, social articulation with the greater American society, stress, cross-cultural misunderstanding, and outright prejudice can all compound the problems encountered for the chronically ill or disabled individual in a multicultural society.

    Background Due to the quick rhythm of life and work pressure, more and more people suffer from sleep quality problems. In this study, we investigated the effect of electroacupuncture on sleep quality of chronic insomniacs and the safety of electroacupuncture therapy.Methods Four courses of electroacupuncture treatment were applied to 47 patients. With pre-treatment and post-treatment self-control statistical method, Pittsburgh sleep quality index (PSQI) scores were used for evaluating sleep quality. Polysomnogram was used for detecting insomniacs' changes in sleep architecture. The safety of electroacupuncture was evaluated by monitoring the self-designed adverse events and side effects during treatment and post-treatment.Results Electroacupuncture considerably improved insomniacs' sleep quality and social function during the daytime.Electroacupuncture had certain repairing effect on the disruption in sleep architecture. At the same time,electroacupuncture prolonged slow wave sleep (SWS) time and relatively rapid eye movement sleep (REM sleep) time.There was no hangover, addiction or decrements in vigilance during the daytime (incidence rate was 0). However,insomnia rebound rate was about 23% within one month.Conclusions These results suggest that electroacupuncture has beneficial effect on sleep quality improvement in the patients with chronic insomnia, which may be associated with repairing sleep architecture, reconstructing sleep continuity,as well as prolonging SWS time and REM sleep time. Electroacupuncture treatment for chronic insomnia is safe.Therefore, electroacupuncture therapy could be a promising avenue of treatment for chronic insomnia.

    Chang, Ku-Lang; Fillingim, Roger; Hurley, Robert W; Schmidt, Siegfried

    2015-05-01

    Nonpharmacologic therapies have become a vital part of managing chronic pain (CP). Although these can be used as stand-alone therapies, nonpharmacologic treatments often are used to augment and complement pharmacologic treatments (ie, multimodal therapy). Nonpharmacologic approaches can be classified as behavioral, cognitive, integrative, and physical therapies. Core principles in developing a treatment plan are explaining the nature of the CP condition, setting appropriate goals, and developing a comprehensive treatment approach and plan for adherence. Clinicians should become familiar with these interventions so that they can offer patients flexibility in the pain management approach. Effective noninvasive treatment modalities for CP include behavioral therapy for short-term pain relief; cognitive behavioral therapy for reducing long-term pain and disability; hypnosis as adjunctive therapy; guided imagery, diaphragmatic breathing, and muscle relaxation, especially for cancer-related pain; mindfulness-based stress reduction for patients with chronic low back pain; acupuncture for multiple pain conditions; combination manipulation, manual therapy, endurance exercise, stretching, and strengthening for chronic neck pain; animal-assisted therapy; and S-adenosyl-L-methionine for joint pain. Guidelines for use of these treatment modalities are based on expert panel recommendations in combination with data from randomized controlled trials. PMID:25970869

    Full Text Available Any link between pancreatic carcinoma and chronic pancreatitis could reflect the malignant potential of a chronic inflammatory process. Four patients with ductal adenocarcinomas had a long history of pancreatic pain (median duration 5 years and showed clearcut evidence of chronic pancreatitis “downstream” of the tumour. Four were alcoholics and two heavy smokers. These four cases arose within a surgical series of approximately 250 patients with chronic pancreatitis, giving an incidence of 1.6 per cent. The incidence and anatomical distribution of carcinoma and chronic pancreatitis could possibly be consistent with a casual relationship.

    Asensi Alvarez, V; Cartón Sánchez, J A; Maradona Hidalgo, J A; López-Larrea, C; Arribas Castrillo, J M

    1992-11-01

    We have studied several aspects of cellular and humoral immunity in 19 patients with chronic osteomyelitis (CO) compared with 11 healthy controls of similar characteristics. Patients with CO showed significantly higher values of GSR, reactive protein C (RPC), IgG and lymphocytes CD3+ and lower values of the CD4+/CD3+ ratio, as well as an hypoergic response to 7 antigens in the different cutaneous hypersensibility tests, compared with healthy controls. The rate of "in vitro" blastic stimulation by different lectins was significantly lower in the group of patients, compared with controls. These changes in the cellular immunity are not correlated with the extent, chronicity and prognosis of the disease, although we did not performed sequential studies of the immunitary condition. None of these immunological markers seem to be a better predictor of the bone infectious activity than the traditional GSR or RPC. PMID:1467399

    2008-08-01

    This paper explores the economic implications of vouchers for chronic disease management with respect to achieving objectives of equity and efficiency. Vouchers as a payment policy instrument for health care services have a set of properties that suggest they may address both demand-side and supply-side issues, and contribute to equity and efficiency. They provide a means whereby health care services can be targeted at selected groups, enabling consumer choice of provider, and encouraging competition in the supply of health services. This analysis suggests that, when structured appropriately, vouchers can support consumers to choose services that will meet their health care needs and encourage competition among providers. Although they may not be appropriate across the entire health care system, there are features of vouchers that make them a potentially attractive option, especially for the management of chronic disease.

    Danilov, Andrei; Kurganova, Julia

    2016-06-01

    Melatonin is a neurohormone secreted by epiphysis and extrapineal structures. It performs several functions including chronobiotic, antioxidant, oncostatic, immune modulating, normothermal, and anxiolytic functions. Melatonin affects the cardiovascular system and gastrointestinal tract, participates in reproduction and metabolism, and body mass regulation. Moreover, recent studies have demonstrated melatonin efficacy in relation to pain syndromes. The present paper reviews the studies on melatonin use in fibromyalgia, headaches, irritable bowel syndrome, chronic back pain, and rheumatoid arthritis. The paper discusses the possible mechanisms of melatonin analgesic properties. On one hand, circadian rhythms normalization results in sleep improvement, which is inevitably disordered in chronic pain syndromes, and activation of melatonin adaptive capabilities. On the other hand, there is evidence of melatonin-independent analgesic effect involving melatonin receptors and several neurotransmitter systems. PMID:26984272

    Radiation enteritis is defined as the loss of absorptive capacity of the intestine following irradiation, which is most commonly seen after radiotherapy for pelvic and abdominal malignancies. It is divided into acute and chronic forms and usually presents with diarrhea and malabsorption. Malnutrition is a common complication of chronic radiation enteritis (CRE). We reviewed the etiology, prevalence, symptoms, diagnosis and management of CRE and CRE with malnutrition in this article. Functional short bowel syndrome as a cause of malnutrition in CRE is also considered. The diagnostic work-up includes serum markers, endoscopy, cross-sectional imaging and the exclusion of alternative diagnoses such as recurrent malignancy. Management options of CRE include dietary manipulation, anti-motility agents, electrolyte correction, probiotics, parenteral nutrition, surgical resection and small bowel transplantation. Treatment may also be required for coexisting conditions including vitamin B12 deficiency, bile acid malabsorption and depression.

    2009-09-01

    Insomnia is highly prevalent in patients with chronic disease including chronic heart failure (CHF) and is a significant contributing factor to fatigue and poor quality of life. The pathophysiology of CHF often leads to fatigue, due to nocturnal symptoms causing sleep disruption, including cough, orthopnea, paroxysmal nocturnal dyspnea, and nocturia. Inadequate cardiac function may lead to hypoxemia or poor perfusion of the cerebrum, skeletal muscle, or visceral body organs, which result in organ dysfunction or failure and may contribute to fatigue. Sleep disturbances negatively affect all dimensions of quality of life and is related to increased risk of comorbidities, including depression. This article reviews insomnia in CHF, cardiac medication side-effects related to sleep disturbances, and treatment options. PMID:18758945

    Wai W. Cheung

    2010-01-01

    Full Text Available Patients with chronic kidney disease (CKD often exhibit symptoms of anorexia and cachexia, which are associated with decreased quality of life and increased mortality. Chronic inflammation may be an important mechanism for the development of anorexia, cachexia, renal osteodystrophy, and increased cardiovascular risk in CKD. Ghrelin is a gastric hormone. The biological effects of ghrelin are mediated through the growth hormone secretagogue receptor (GHSR. The salutary effects of ghrelin on food intake and meal appreciation suggest that ghrelin could be an effective treatment for anorexic CKD patients. In addition to its appetite-stimulating effects, ghrelin has been shown to possess anti-inflammatory properties. The known metabolic effects of ghrelin and the potential implications in CKD will be discussed in this review. The strength, shortcomings, and unanswered questions related to ghrelin treatment in CKD will be addressed.

  20. Biomarkers in chronic adult hydrocephalus

    Kitchen Neil D

    2006-10-01

    Full Text Available Abstract Awareness of the importance of chronic adult hydrocephalus has been raised again with the recent emergence of epidemiological studies. It is estimated that between 5 and 10% of patients suffering from dementia might, in fact, have chronic hydrocephalus. Although, surgical diversion of the cerebrospinal fluid (CSF represents the only known procedure able to treat the symptoms of this condition, the selection of surgical patients has always been problematic. In the last 40 years, we have become wiser in using appropriate diagnostic tests for the selection of these patients; however, the area of biological markers has so far been overlooked in this condition, in contrast to that for other neurodegenerative disorders and dementias. Biomarkers are biological substances that may be used to indicate either the onset or the presence, and the progression of a clinical condition, being closely linked to its pathophysiology. In such a setting they might assist in the more appropriate selection of patients for shunt surgery. In this article, we have reviewed research carried out in the last 25 years regarding the identification of serum and CSF biomarkers for chronic hydrocephalus, discussed the potential for each one, and finally discussed the limitations for use, as well as future directions and possibilities in this field. It is concluded that tumour-necrosis factor, tau protein, lactate, sulfatide and neurofilament triple protein are the most promising CSF markers for chronic hydrocephalus. At present however, none of these meet the criteria required to justify a change clinical practice. In the future, collaborative multi-centre projects will be needed to obtain more substantial data that overcome the problems that arise from small individual and uncoordinated studies.

    The differential diagnosis between pancreatic cancer and chronic pancreatitis is very important as the management and prognosis of these two diseases is different. In most patients with pancreatic disease, the diagnosis can be established but there is a subgroup of patients in whom it is difficult to differentiate between these conditions because the clinical presentation is often similar and currently available diagnostic tests may be unable to distinguish between an inflammatory or neoplast...

    Chronic bacterial infection is implicated in both the development and severity of asthma. The atypical bacteria Mycoplasma pneumoniae and Chlamydophila pneumoniae have been identified in the airways of asthmatics and correlated with clinical features such as adult onset, exacerbation risks, steroid sensitivity, and symptom control. Asthmatic patients with evidence of bacterial infection may benefit from antibiotic treatment directed towards these atypical organisms. Examination of the airway microbiome may identify microbial communities that confer risk for or protection from severe asthma. PMID:27401621

    Full Text Available Nitric oxide (NO is thought to play an important role in modulating the inflammatory response by virtue of its ability to affect bloodflow, leukocyte function and cell viability. The objective of this study was to assess the role that NO may play in mediating the mucosal injury and inflammation in a model of chronic granulomatous colitis using two pharmacologically different inhibitors of nitric oxide synthase (NOS. Chronic granulomatous colitis with liver and spleen inflammation was induced in female Lewis rats via the subserosal (intramural injection of peptidoglycan/polysaccharide (PG/PS derived from group A streptococci. Chronic NOS inhibition by oral administration of NG-nitro-L-arginine methyl ester (L-NAME (15 µmol/kg/day or amino-guanidine (AG (15 µmol/ kg/day was found to attenuate the PG/PS-induced increases in macroscopic colonic inflammation scores and colonic myeloperoxidase activity. Only AG -- not L-NAME – attenuated the PG/PS-induced increases in colon dry weight. Both L-NAME and AG significantly attenuated the PG/PS-induced increases in spleen weight whereas neither was effective at significantly attenuating the PG/PS-induced increases in liver weight. Although both L-NAME and AG inhibited NO production in vivo, as measured by decreases in plasma nitrite and nitrate levels, only AG produced significantly lower values (38±3 versus 83±8 µM, respectively, P<0.05. Finally, L-NAME, but not AG, administration significantly increased mean arterial pressure from 83 mmHg in colitic animals to 105 mmHg in the PG/PS+ L-NAME-treated animals (P<0.05. It is concluded that NO may play an important role in mediating some of the pathophysiology associated with this model of chronic granulomatous colitis.

  12. Comprehensive management of chronic pain in haemophilia.

    Young, G; Tachdjian, R; Baumann, K; Panopoulos, G

    2014-03-01

    Chronic pain, most often due to haemophilic arthropathy, is a pervasive problem in persons with haemophilia (PWH) that adversely impacts function and quality of life. PWH with inhibitors and older PWH may be especially vulnerable to progressive arthropathy and resulting chronic pain. The development of chronic pain from acute pain involves a complex interplay of biological and psychosocial factors that may all contribute to the perpetuation of chronic pain and the outcome of therapy. In the absence of evidence-based guidelines, an individualized, multimodal approach to chronic pain management is proposed, as it is in individuals without haemophilia who have chronic pain. Pharmacological treatment is central to the management of chronic pain and must be modified based on pain intensity, ongoing response to therapy and the risk for adverse events. Non-pharmacological interventions, including physiotherapy, complementary treatments and surgical (e.g. orthopaedic) or other invasive procedures, may be integral to chronic pain management in this population. Ongoing psychosocial assessment is critical to identify those factors that may be contributing to the perpetuation of chronic pain or acting as barriers to effective management. Additional study is needed to identify optimal pharmacological treatments for chronic pain in PWH based on the unique pathophysiology of haemophilic arthropathy and on risk profile. Systematic determination of the particular psychosocial factors impacting the experience and management of chronic pain in PWH would likewise add value to the treatment of this pervasive problem.

    , composed of pairs of non chagasic persons with the same age and sex, was shown to be 27.4% higher than among patients with positive serology. This factor represents the excess risk or exclusively chagasic component in the development of the disease. No differences were observed by sex related to the development of the disease. It was more premature and seven times more frequent however when related to the cardiopathy than to the megaesophagus. Both conditions occurring mainly in slight or moderate degree. In 192 chagasic patients and 188 non chagasic persons observed in that area in the same period, the mortality was 3.6 times higher among the chagasic patients with a letality due to cardiopathy of 8.9% without difference between sexes but more premature among the males. Sudden death was more frequent than that one caused by cardiac insufficiency. The prognostic was good for the patients with indeterminate and digestive forms and reserved for patients with the highest degree of cardiopathy.

    2009-12-01

    Otitis media (OM) is a common illness in young children. OM has historically been associated with frequent and severe complications. Nowadays it is usually a mild condition that often resolves without treatment. For most children, progression to tympanic membrane perforation and chronic suppurative OM is unusual (low-risk populations); this has led to reevaluation of many interventions that were used routinely in the past. Evidence from a large number of randomized controlled trials can help when discussing treatment options with families. Indigenous children in the United States, Canada, Northern Europe, Australia, and New Zealand experience more OM than other children. In some places, Indigenous children continue to suffer from the most severe forms of the disease. Communities with more than 4% of the children affected by chronic tympanic membrane perforation have a major public health problem (high-risk populations). Higher rates of invasive pneumococcal disease, pneumonia, and chronic suppurative lung disease (including bronchiectasis) are also seen. These children will often benefit from effective treatment of persistent (or recurrent) bacterial infection. PMID:19962027

    When peritoneal dialysis is inapplicable, chronic hemodialysis (HD) becomes the only available treatment option in small children. Due to small patient size, central venous catheters (CVC) are mainly used for vascular access. Over the past 4 years, four children weighing less than 15 kg received chronic HD in our unit. A total of 848 dialysis sessions were performed. Altogether, 21 catheters were inserted. In all but one occasion, uncuffed catheters were used. Catheter revision was performed 15 times during the study period, either due to infection or catheter malfunction. The median number of catheter revisions and the median line survival was 3.0/patient-year and 53 days (range; 6-373 days), respectively. There were 14 episodes of catheter related infections requiring 11 CVC revisions (78.6%). The median rate of line infections was 2.8/patient-year. Chronic HD in small children is demanding and labor intensive. Issues pertain mainly to CVCs and limit its long-term use. PMID:27312919

    Objective To evaluate the improving reliability and safety of thromboendarterectomy and perioperative management for chronic pulmonary thromboembolism. Methods The clinical data of 12 cases with chronic pulmonary thromboembolism, who underwent thromboendarterec tomy assisted by low flow or circulation arrest with deep hypothermia, were reviewed retrospectively. Results Pulmonary artery pressure decreased 20 to 40 mmHg immediately after surgical procedures in 9 cases. The postoperative pulmonary edema at various degrees happened in 12 cases, among them, 1 died of severe lung infection and pulmonary re-embolism at 19 days postoperation. Computed tomography pulmonary angiography and angiography of 11 cases indicated that the original obstruction of pulmonary artery disappeared. During the follow-up period of 2 months to 5 years, the clinical symptoms and activity was improved. Conclusion Thromboendarterectomy is an effective treatment for chronic pulmonary thromboembolism. The outcome of the surgical procedure needs to be further investigated and followed up regularly according to an evaluative system, because it might be influenced by multiple factors.

    Many chronic renal diseases lead to the final common state of decrease in renal size, parenchymal atrophy, sclerosis and fibrosis. The ultrasound image show a smaller kidney, thinning of the parenchyma and its hyperechogenicity (reflecting sclerosis and fibrosis). The frequency of renal cysts increases with the progression of the disease. Ultrasound generally does not allow for the exact diagnosis of an underlying chronic disease (renal biopsy is usually required), but it can help to determine an irreversible disease, assess prognosis and avoid unnecessary diagnostic or therapeutic procedures. The main exception in which the ultrasound image does not show a smaller kidney with parenchymal atrophy is diabetic nephropathy, the leading cause of chronic and end-stage renal failure in developed countries in recent years. In this case, both renal size and parenchymal thickness are preserved until end-stage renal failure. Doppler study of intrarenal vessels can provide additional information about microvascular and parenchymal lesions, which is helpful in deciding for or against therapeutic intervention and timely planning for optimal renal replacement therapy option.

  18. Pericytes in chronic lung disease.

    Rowley, Jessica E; Johnson, Jill R

    2014-01-01

    Pericytes are mesenchymal cells embedded within the abluminal surface of the endothelium of microvessels such as capillaries, pre-capillary arterioles, post-capillary and collecting venules, where they maintain microvascular homeostasis and participate in angiogenesis. In addition to their roles in supporting the vasculature and facilitating leukocyte extravasation, pericytes have been recently investigated as a subpopulation of mesenchymal stem cells (MSCs) due to their capacity to differentiate into numerous cell types including the classic MSC triad, i.e. osteocytes, chondrocytes and adipocytes. Other studies in models of fibrotic inflammatory disease of the lung have demonstrated a vital role of pericytes in myofibroblast activation, collagen deposition and microvascular remodelling, which are hallmark features of chronic lung diseases such as asthma, chronic obstructive pulmonary disorder, pulmonary fibrosis and pulmonary hypertension. Further studies into the mechanisms of the pericyte-to-myofibroblast transition and migration to fibrotic foci will hopefully clarify the role of these cells in chronic lung disease and confirm the importance of pericytes in human fibrotic pulmonary disease.

    2004-01-01

    Full Text Available Chronic Daily Headache (CDH generally refers to frequent headache occuring more than 15 days/month for over three months. Such headaches may be primary or secondary - the latter referring to headaches related to identifiable intra and extracranial vascular or other pathologies or systemic illnesses. The primary type may be subclassified as short and long lasting ones, depending upon whether the headache spells are more or less than four hours in duration. The present review would deal with the four major types of long lasting primary CDH which include Chronic migraine (CM, Chronic tension type headache (CTTH, New daily persistent headache (NDPH and Hemicrania continua (HC. The first part of the article would focus on the clinical pattern recognising features of these types. The relationship of medication overuse to CM would be critically evaluated. In the second part, the status of CDH in the recently proposed classification of headache disorders by the International Headache Society would be briefly evaluated. In the next section the clinical Profile or CDH in Indian patients would be highlighted based on available published data. Lastly, the pathophysiology of this vexing condition would be discussed specially in relation to CM and postulating on how it may evolve from episodic migraine.

    We studied the associations of widespread pain with other pain and functional measures among patients with chronic epicondylitis. A total of 190 patients (66% females) participated in the study; with a mean age 43.7, mean duration of symptoms 48weeks, chronic lateral (n=160) and medial (n=30) epicondylitis. We analysed clinical status, grip strength and cubital pain thresholds and interviewed pain and disability, leisure time physical activity, strenuous hobby activities for arms, duration of symptoms, other systemic and upper extremity disorders, arm operations, and work ability. The location of pain was analysed using a whole-body pain drawing, categorized into three groups; the highest of which was classified as widespread pain. A total of 85 patients (45%) reported widespread pain. It was highly associated with female gender, high pain scores, decreased grip strength and pain thresholds (p<0.001 for all), with increased number of positive manual tests, low level of hobby strain for arms and physical activity, long duration of symptoms, and sick leave (p for all <0.05). It was also related to upper extremity disorders and arm surgery, but not with operated epicondylitis, other systemic diseases, workload or work ability. In addition, 39% of patients without other disease reported widespread pain. Widespread pain is common in chronic epicondylitis with and without other diseases, and is related to high pain scores, decreased function of the arm, long duration of symptoms, sick leave, and with a low level of physical activity.

    The efficacy of non-pharmacological intervention for chronic insomnia has been proven by several meta-analytic reviews, an NIH report, an American Academy of Sleep Medicine review, and numerous clinical trials. Behavior therapy for chronic insomnia consists of relaxation, stimulus control, sleep restriction, cognitive restructuring and sleep hygiene education, which has produced reliable and durable changes in total sleep time, sleep onset latency, number and duration of awakening. These studies also showed that the post-treatment effect of behavior therapy is equal to that of hypnotic therapy, and that these effects were maintained for 6 months on follow-up assessment. Elderly insomniac patients would gain considerable benefit from behavioral treatments because there are no adverse physical effects as there are from pharmacological therapy. The authors present the basic theory, techniques of behavior therapy for insomnia, and the results of two important key meta-analytic reviews. Any behavioral approach such as convenient education, self-care enhancement by bibliotherapy, and individual face-to-face counseling, seem to be fruitful not only for American but also Japanese insomnia patients. Nonetheless, there are no currently actual intervention studies using behavior therapy in Japan. We have discussed the methodology of intervention study and published a behavioral self-help manual for people with sleep problems. Development of a behavioral approach to chronic insomnia seemed to be very beneficial and a useful contribution to mental health services. PMID:12373807

  2. Asthma and chronic obstructive pulmonary disease overlap: asthmatic chronic obstructive pulmonary disease or chronic obstructive asthma?

    2016-02-01

    Asthma and chronic obstructive pulmonary disease (COPD) are different disease entities. They are both clinical diagnoses, with diagnostic tools to discriminate between one another. However, especially in older patients (>55 years) it seems more difficult to differentiate between asthma and COPD. This has led to the definition of a new phenotype called asthma COPD overlap syndrome (ACOS). However, our understanding of ACOS is at a very preliminary stage, as most research has involved subjects with existing diagnoses of asthma or COPD from studies with different definitions for ACOS. This has led to different and sometimes opposing results between studies on several features of ACOS, also depending on the comparison with COPD alone, asthma alone or both, which are summarized in this review.We suggest not using the term ACOS for a patient with features of both asthma and COPD, but to describe a patient with chronic obstructive airway disease as completely as possible, with regard to characteristics that determine treatment response (e.g. eosinophilic inflammation) and prognosis (such as smoking status, exacerbation rate, fixed airflow limitation, hyperresponsiveness, comorbidities). This will provide a far more clinically relevant diagnosis, and would aid in research on treatment in more homogenous groups of patients with chronic airways obstruction. More research is certainly needed to develop more evidence-based definitions for this patient group and to evaluate biomarkers, which will help to further classify these patients, treat them more adequately and unravel the underlying pathophysiological mechanism.

    Chronic migraine has a great detrimental influence on a patient's life, with a severe impact on socioeconomic functioning and quality of life. Chronic migraine affects 1-2% of the general population, and about 8% of patients with migraine; it usually develops from episodic migraine at an annual conversion rate of about 3%. The chronification is reversible: about 26% of patients with chronic migraine go into remission within 2 years of chronification. The most important modifiable risk factors for chronic migraine include overuse of acute migraine medication, ineffective acute treatment, obesity, depression and stressful life events. Moreover, age, female sex and low educational status increase the risk of chronic migraine. The pathophysiology of migraine chronification can be understood as a threshold problem: certain predisposing factors, combined with frequent headache pain, lower the threshold of migraine attacks, thereby increasing the risk of chronic migraine. Treatment options include oral medications, nerve blockade with local anaesthetics or corticoids, and neuromodulation. Well-defined diagnostic criteria are crucial for the identification of chronic migraine. The International Headache Society classification of chronic migraine was recently updated, and now allows co-diagnosis of chronic migraine and medication overuse headache. This Review provides an up-to-date overview of the classification of chronic migraine, basic mechanisms and risk factors of migraine chronification, and the currently established treatment options.

    Full Text Available OBJECTIVE: To evaluate the association between endometriosis and chronic endometritis. METHODS: Endometrial specimens were obtained from 71 patients, 34 with endometriosis (endometriosis group and 37 without endometriosis (non-endometriosis group, who underwent hysterectomy, and the specimens were immunostained for the plasmacyte marker CD138. The rate of chronic endometritis was compared between the endometriosis group and the non-endometriosis group. Furthermore, the 71 patients were also divided into two groups, 28 with chronic endometritis (chronic endometritis group and 43 without chronic endometritis (non-chronic endometritis group. Logistic regression analysis was performed with variables including age, body mass index (BMI, gravidity and parity, and diagnoses of leiomyoma, adenomyosis, and endometriosis on pathology to examine the independent effect of each variable on chronic endometritis. Patients suffering from cervical invasive carcinoma, endometrial carcinoma, and endometrial polyps or treated with gonadotropin-releasing hormone agonists, progestins, or oral contraceptives before surgery were excluded. RESULTS: Chronic endometritis was identified in 52.94% of the endometriosis group and 27.02% of the non-endometriosis group (p<0.05. Logistic regression analysis revealed that endometriosis was associated with chronic endometritis. CONCLUSIONS: This result suggests a strong association between endometriosis and chronic endometritis.

    Full Text Available Chronic pelvic pain (CPP is a common condition that has a major impact on the quality of life of both men and women. Male CPP is usually attributable to well-defined urogenital conditions (most frequently infectious/non infectious prostatic diseases or musculoskeletal or bowel diseases, whereas the features of female CPP are much more complex and are of particular clinical and epidemiological importance. It is a multifactorial syndrome that can be due to diseases of the urogenital, gastrointestinal, or musculoskeletal systems, or to neurological or neuropsychiatric disorders. It is not always easy to identify its predominant pathogenesis, although it often occurs as a central sensitization syndrome triggered by an initial stimulus which is no longer detectable and only manifests itself clinically through pain. In this respect, there are some very interesting relationships between vulvodynia and fibromyalgic syndrome, as identified in a preliminary study of women with chronic musculoskeletal pain in which it was demonstrated that vulvar pain plays an important role, although it is often overlooked and undiagnosed.

    Insomnia affects 10% to 30% of the population with a total cost of $92.5 to $107.5 billion annually. Short-term, chronic, and other types of insomnia are the three major categories according to the International Classification of Sleep Disorders, 3rd ed. The criteria for diagnosis are difficulty falling asleep, difficulty staying asleep, or early awakening despite the opportunity for sleep; symptoms must be associated with impaired daytime functioning and occur at least three times per week for at least one month. Factors associated with the onset of insomnia include a personal or family history of insomnia, easy arousability, poor self-reported health, and chronic pain. Insomnia is more common in women, especially following menopause and during late pregnancy, and in older adults. A comprehensive sleep history can confirm the diagnosis. Psychiatric and medical problems, medication use, and substance abuse should be ruled out as contributing factors. Treatment of comorbid conditions alone may not resolve insomnia. Patients with movement disorders (e.g., restless legs syndrome, periodic limb movement disorder), circadian rhythm disorders, or breathing disorders (e.g., obstructive sleep apnea) must be identified and treated appropriately. Chronic insomnia is associated with cognitive difficulties, anxiety and depression, poor work performance, decreased quality of life, and increased risk of cardiovascular disease and all-cause mortality. Insomnia can be treated with nonpharmacologic and pharmacologic therapies. Nonpharmacologic therapies include sleep hygiene, cognitive behavior therapy, relaxation therapy, multicomponent therapy, and paradoxical intention. Referral to a sleep specialist may be considered for refractory cases. PMID:26760592

    Full Text Available Background: Helicobacter pylori (HP have recently emerged as a novel eliciting factor for chronic urticaria (CU. The possible association between HP and CU has enormous potential, as eradicating HP could cure CU. Aims and Objectives: We conducted a study to assess the prevalence of HP infection and effect of bacterium eradication on skin lesions in patients of chronic idiopathic urticaria (CIU. Settings and Design: Four hundred sixty patients of CU attending the allergy clinic, SMS hospital, Jaipur during the period February 6, 2004, to February 6, 2006, were screened for possible eliciting factors. Patients with CIU were enrolled and others were excluded. Materials and Methods: Sixty-eight patients of CIU and similar number of age and sex matched controls, attending the allergy clinic, SMS Hospital, Jaipur were enrolled in the study. All patients underwent endoscopy with antral biopsy for urease and histopathology to identify HP-associated gastritis. Infected patients were given HP eradication therapy. Eradication of bacterium was confirmed by fecal antigen assay. Subjective response to treatment was judged using chronic urticaria quality-of-life questionnaire (CU-Q 2 oL while objective response to treatment was judged by need for ′rescue medication′ (antihistaminics. Statistical Analysis: Data were analyzed using Chi square and paired′t′ test for their level of significance. Results: HP associated gastritis was present in 48 (70.58% patients, out of which 39 (81.25% patients responded to eradication therapy. Ten (50.00% patients without HP associated gastritis showed response to symptomatic therapy. Overall 49 (72.05% patients responded and 19 (27.94% showed no response. The value of χ2 was 28.571 (P = 0.003, which showed significant association between presence of HP and response to eradication regimen. Conclusion: The response of HP eradication therapy in infected patients of CIU is significant. HP should be included in diagnostic

    Full Text Available Com o objetivo de avaliar a junção tiroidiana após uso crônico da amiodarona, em área de deficiência de iodo e endemia chagásica, 24 pacientes foram analisados antes e após três e nove meses de uso da droga. A avaliação constou de exame clínico, dosagem sérica de T4, T3, rT3, TSH, anticorpo antitiroglobulina e TSH 30 minutos após infusão venosa de uma ampola de 200µg de TRH. A captação do iodo radioativo 131 e a cintilografia datiróide foram realizadas antes e aos 9 meses após tratamento. Disfunção tiroidiana ocorreu em 20,8% dos pacientes sendo 12,5% de hipertiroidismo e 8,3% de hipotiroidismo, com anticorpos antitiroglobulina negativos. Captação do iodo radioativo 131 foi positiva em um paciente hipertiroideo com bócio. O diagnóstico de hipertiroidismo foi melhor evidenciado pela resposta reduzida ou bloqueada do TSH ao TRH e não pela concentração do T3 no soro e o de hipotiroidismo pela concentração elevada do TSH. O TSH elevado desde o início do tratamento pode predispor ao aparecimento de bócio. Concluímos que o uso da amiodarona em nossa região deve serjudiciosamente analisado, sendo a função tiroidiana cuidadosamente monitorizada antes e durante o tratamento.In order to evaluate the development of thyroid dysfunction during chronic amiodarone treatment in an area deficient in iodine and endemic for Chagas 'disease, a group of 24patients wasprospectively studied.

    There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: "chronic Lyme disease" and "posttreatment Lyme disease syndrome." In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.

    Full Text Available Chronic spontaneous urticaria is a distressing disease encountered frequently in clinical practice. The current mainstay of therapy is the use of second-generation, non-sedating antihistamines. However, in patients who do not respond satisfactorily to these agents, a variety of other drugs are used. This article examines the available literature for frequently used agents including systemic corticosteroids, leukotriene receptor antagonists, dapsone, sulfasalazine, hydroxychloroquine, H2 antagonists, methotrexate, cyclosporine A, omalizumab, autologous serum therapy, and mycophenolate mofetil, with an additional focus on publications in Indian literature.

    Chronic spontaneous urticaria is defined as persistent symptoms of urticaria for 6 weeks or more. It is associated with autoimmunity in approximately 45 percent of patients. Therapy is often difficult however the initial approach should employ high-dose non-sedating antihistamines; 4-6 tablets/day may be necessary. It has been shown that the response to 4 tablets/day exceeds 3, and exceeds 2, which exceeds 1. However the dose that corresponds to the maximal dose of first generation antihistam...

    Full Text Available On HRCT scans, lung cysts are characterized by rounded areas of low attenuation in the lung parenchyma and a well-defined interface with the normal adjacent lung. The most common cystic lung diseases are lymphangioleiomyomatosis, Langerhans cell histiocytosis, and lymphocytic interstitial pneumonia. In a retrospective analysis of the HRCT findings in 50 patients diagnosed with chronic paracoccidioidomycosis, we found lung cysts in 5 cases (10%, indicating that patients with paracoccidioidomycosis can present with lung cysts on HRCT scans. Therefore, paracoccidioidomycosis should be included in the differential diagnosis of cystic lung diseases.

    2002-01-01

    Pancreatic cancer is the fourth leading cause of cancer deaths in the USA in both sexes. Early diagnosis is difficult and the overall mortality rate is high. Individuals at high risk for pancreatic cancer include smokers, and persons with all forms of chronic alcoholic, metabolic, tropical or hereditary pancreatitis. The duration of exposure to inflammation seems to be the major factor involved in the transition from benign to malignant condition. Smoking, which appears to further accelerate the carcinogenic transformation, remains the strongest risk factor amenable to preventive intervention.

    Westervelt, Holly James; McCaffrey, Robert J

    2002-09-01

    Lyme disease is currently the most common vector-borne illness in the United States. The disease is multisystemic, and chronic disease, in particular, may be associated with neuropsychological deficits. However, to date, only a few empirical studies exist, which examine the neuropsychological sequelae associated with chronic Lyme disease. A review of the literature shows that the deficits observed in adults with chronic Lyme disease are generally consistent with the deficits that can be seen in processes with primarily frontal systems involvement. These observations are generally consistent with neuroradiologic findings. The clinical presentation in chronic Lyme disease and the nature of the neuropsychological deficits are discussed, as are several central issues in understanding neuropsychological functioning in chronic Lyme disease, such as the impact of chronic illness, response to treatment, and the relationship between neuropsychological performance and depression, fatigue, and neurological indicators of disease.

    The aetiology of chronic idiopathic intestinal inflammation is unknown. It is characterized by a diffuse infiltration with inflammatory cells into the intestinal mucosa and sometimes submucosa. Cats with chronic intermittent vomiting and diarrhoea, later on accompanied by anorexia and weight loss, are presented. Definitive diagnosis can be obtained by intestinal biopsy only. An immune pathogenesis is suspected, which is supported by the fact, that chronic inflammatory bowel disease responds to steroid therapy.

  11. Radiolabelled cytokines for imaging chronic inflammation

    International Nuclear Information System (INIS)

    Diagnosis and particularly follow-up of chronic inflammatory disorders could be often difficult in clinical practice. Indeed, traditional radiological techniques reveal only structural tissue alterations and are not able to monitor functional changes occurring in tissues affected by chronic inflammation. The continuous advances in the knowledge of the pathophysiology of chronic disorders, combine with the progress of radiochemistry, led to the development of new specific radiolabelled agents for the imaging of chronic diseases. In this scenario, cytokines, due to their pivotal role in such diseases, represent good candidate as radiopharmaceuticals. (author)

    Chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. Vitamin D is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. This study was performed to evaluate the relationship between vitamin D levels and susceptibility to chronic idiopathic urticaria. One hundred and fourteen patients with chronic idiopathic urticaria were recruited in this study along with one hundred and eighty seven sex-matched and age-matched healthy volunteers as the control group. For each patient, urticaria activity score was calculated and autologous serum skin test was done. Vitamin D metabolic statue was measured in serum as 25 hydroxyvitamin D using enzyme immunoassay method. Patients with chronic idiopathic urticaria significantly showed lower levels of vitamin D. Vitamin D deficiency was significantly associated with increased susceptibility to chronic idiopathic urticaria. There was a significant positive correlation between vitamin D levels and urticaria activity score. This study showed that patients with chronic idiopathic urticaria had reduced levels of vitamin D, while vitamin D deficiency could increase susceptibility to chronic idiopathic urticaria.

    2014-10-01

    The chronic stress model was developed on the basis of the stress-diathesis hypothesis of depression. However, these behavioural responses associated with different stress paradigms are quite complex. This study examined the effects of two chronic stress regimens on anxiety-like and depressive behaviours. C57BL/6 mice were subjected to unpredictable chronic mild stress or to chronic restraint stress for 4 weeks. Subsequently, both anxiety-like behaviours (open field, elevated plus maze and novelty suppressed feeding) and depression-like behaviours (tail suspension, forced swim and sucrose preference) were evaluated. Both chronic stress models generated anxiety-like behaviours, whereas only unpredictable chronic mild stress could induce depressive behaviours such as increased immobility and decreased sucrose consumption. These results of the present study provide additional evidence on how chronic stress affects behavioural responses and point to the importance of the validity of animal models of chronic stress in studying depression.

    A modern pahtogenetic and etiological classification of pancreatic diseases is observed in the review and the questions of dietotherapy concerning the main forms of the disease are under consideration. There are numerous sources given from literature where the question is discussed on the fiber level, quantitative and qualitative structure of the fatty part of the ration in case of chronic pancreatitis. The majority of native and foreign authors consider it inexpedient to reduce fiber lover than 120 g per day, however there is a number of works where it is recommended to increase in the ration the quantity of carbohydrates up to 400 g, reducing some fiber at the same time. There has appeared a number of works for the recent years, where it is recommended to include mixes for enteral nutrition into the diets recommended both for acute and chronic course of the disease. Such diets are emphasized to be well bearable and high effective during the treatment of this disease. PMID:17313040

    Chronic rhinosinusitis without nasal polyps (CRSsNP) is more prevalent than chronic rhinosinusitis with nasal polyps (CRSwNP). Certain diseases predispose to whereas others are associated with CRSsNP. Predisposing diseases include allergic and nonallergic upper and lower airway diseases, epithelial cell disorders, immunodeficiencies, autoimmune diseases, and some infectious diseases. In addition, environmental and host factors, examples of which include smoking, a higher incidence of abnormal biofilms, and innate immune defects, play a role in the pathogenesis of this disease. CRSsNP is characterized by histologic abnormalities, including basement membrane thickening (fibrosis) and goblet cell hyperplasia. Neutrophils and several chemokines, TGF-β and C-X-C motif chemokine ligand (CXCL)-8, play a role in CRSsNP remodeling. However, there are conflicting data about CRSsNP endotypes, for example, whether it is characterized by neutrophilia or eosinophilia or both. In spite of advancements and the understanding of the pathogenesis of this disease, additional study is necessary to better comprehend its underlying mechanisms, endotypes, and evidence-based treatment strategies.

    2016-01-01

    Chronic rhinosinusitis with nasal polyps (CRSwNP) is an important clinical entity diagnosed by the presence of both subjective and objective evidence of chronic sinonasal inflammation. Symptoms include anterior or posterior rhinorrhea, nasal congestion, hyposmia, and/or facial pressure or pain that last for a duration of more than 12 weeks. Nasal polyps are inflammatory lesions that project into the nasal airway, are typically bilateral, and originate from the ethmoid sinus. Males are more likely to be affected than females, but no specific genetic or environmental factors have been strongly linked to the development of this disorder to date. CRSwNP is frequently associated with asthma and allergic rhinitis, but the cellular and molecular mechanisms that contribute to the clinical symptoms are not fully understood. Defects in the sinonasal epithelial cell barrier, increased exposure to pathogenic and colonized bacteria, and dysregulation of the host immune system are all thought to play prominent roles in disease pathogenesis. Additional studies are needed to further explore the clinical and pathophysiological features of CRSwNP so that biomarkers can be identified and novel advances can be made to improve the treatment and management of this disease.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Epidemiological evidence links an individual's susceptibility to chronic disease in adult life to events during their intrauterine phase of development. Biologically this should not be unexpected, for organ systems are at their most plastic when progenitor cells are proliferating and differentiating. Influences operating at this time can permanently affect their structure and functional capacity, and the activity of enzyme systems and endocrine axes. It is now appreciated that such effects lay the foundations for a diverse array of diseases that become manifest many years later, often in response to secondary environmental stressors. Fetal development is underpinned by the placenta, the organ that forms the interface between the fetus and its mother. All nutrients and oxygen reaching the fetus must pass through this organ. The placenta also has major endocrine functions, orchestrating maternal adaptations to pregnancy and mobilizing resources for fetal use. In addition, it acts as a selective barrier, creating a protective milieu by minimizing exposure of the fetus to maternal hormones, such as glucocorticoids, xenobiotics, pathogens, and parasites. The placenta shows a remarkable capacity to adapt to adverse environmental cues and lessen their impact on the fetus. However, if placental function is impaired, or its capacity to adapt is exceeded, then fetal development may be compromised. Here, we explore the complex relationships between the placental phenotype and developmental programming of chronic disease in the offspring. Ensuring optimal placentation offers a new approach to the prevention of disorders such as cardiovascular disease, diabetes, and obesity, which are reaching epidemic proportions. PMID:27604528

  1. Acute and chronic arsenic toxicity.

    Science.gov (United States)

    Ratnaike, R N

    2003-07-01

    Arsenic toxicity is a global health problem affecting many millions of people. Contamination is caused by arsenic from natural geological sources leaching into aquifers, contaminating drinking water and may also occur from mining and other industrial processes. Arsenic is present as a contaminant in many traditional remedies. Arsenic trioxide is now used to treat acute promyelocytic leukaemia. Absorption occurs predominantly from ingestion from the small intestine, though minimal absorption occurs from skin contact and inhalation. Arsenic exerts its toxicity by inactivating up to 200 enzymes, especially those involved in cellular energy pathways and DNA synthesis and repair. Acute arsenic poisoning is associated initially with nausea, vomiting, abdominal pain, and severe diarrhoea. Encephalopathy and peripheral neuropathy are reported. Chronic arsenic toxicity results in multisystem disease. Arsenic is a well documented human carcinogen affecting numerous organs. There are no evidence based treatment regimens to treat chronic arsenic poisoning but antioxidants have been advocated, though benefit is not proven. The focus of management is to reduce arsenic ingestion from drinking water and there is increasing emphasis on using alternative supplies of water.

    The case of a female 68 years old patient is described. Here, a chronic lead intoxication was diagnosed after a two year old medical history with increasing attacks of colic-like abdominal pain often described as life-threatening. After repeated hospitalizations and intensive search for the cause of the symptoms, porphyria and anemia was found to be a sign of a chronic lead poisoning. The blood lead concentrations were always about a level of 600 {mu}g/L. The source of exposure could not be found by now. Neither home inspection nor environmental investigations have shown a recent source of lead intake by the patient. However, a possible occupational source of lead exposure at a blast furnace was established by anamnesis for 1952 to 1962. Thus, osteoporosis induced lead mobilisation was suspected. Noticeable are the results of the six abdominal survey radiographies taken during hospitalization within one year; three radiographies were taken following clinical admission and three before discharge of the patient. In comparison, the course shows a chronic relapsing alimentary supply from metallic particles of unknown genesis. The patient was treated with the sodium salt of 2,3-dimercapto-1-propansulfonic acid (DMPS, Dimaval{sup TM}). She was free of complain afterwards. Following therapy, the blood lead concentrations fell under a level of 400 {mu}m/L, but after several weeks the lead level raised up to the original level of 600 {mu}g/L. (orig.)

    The case of a 14-year old girl with painful periostitis and ulcerative colitis is reported. The association of chronic inflammatory bowel disease with osteoarthropathy is rare and has previously been reported in eight patients. The periosteal reaction found in association with inflammatory bowel disease is apparently related to a chronic disease course and may cause extreme localized pain.

    Marques, Adriana

    2008-06-01

    Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.

  20. Endoscopic treatment of chronic pancreatitis

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Treatment of chronic pancreatitis has been exclusively surgical for a long time. Recently, endoscopic therapy has become widely used as a primary therapeutic option.Initially performed for drainage of pancreatic cysts and pseudocysts, endoscopic treatments were adapted to biliary and pancreatic ducts stenosis. Pancreatic sphincterotomy which allows access to pancreatic ducts was firstly reported. Secondly, endoscopic methods of stenting, dilatation, and stones extraction of the bile ducts were applied to pancreatic ducts. Nevertheless,new improvements were necessary: failures of pancreatic stone extraction justified the development of extra-corporeal shock wave lithotripsy; dilatation of pancreatic stenosis was improved by forage with a new device; moreover endosonography allowed guidance for celiac block, gastro-cystostomy, duodeno-cystostomy and pancreatico-gastrostomy. Although endoscopic treatments are more and more frequently accepted,indications are still debated.

  1. Chronic recurrent multifocal osteomyelitis (CRMO)

    International Nuclear Information System (INIS)

    Chronic recurrent multifocal osteomyelitis (CRMO) is an unusual clinical entity. More than 200 cases are described in the literature and it is presented here with special reference to its radiological aspects. It is an acquired disease of the skeleton which occurs predominantly during childhood and adolescence. About ten per cent of cases begin in early or, rarely, in later adult life. This variant is described here for the first time and is discussed as 'adult CRMO'. The underlying pathology is a bland, predominantly lympho-plasma cellular osteomyelitis which is self-limiting and leads to bone sclerosis (Garre). It probably involves an abnormal immune process which follows an infection but remains clinically latent and remains aseptic and sterile. In a quarter of cases there is an association with pustulosis palmo-plantaris and its relationship with psoriatic arthropathy is discussed. The clinical, histopathological and imaging features (radiological and particularly MRT) and the bone changes are described. (orig./AJ)

    Full Text Available Lenalidomide is an oral immunomodulatory drug used in multiple myeloma and myelodysplastic syndrome and most recently it has shown to be effective in the treatment of various lymphoproliferative disorders such as chronic lymphocytic leukemia (CLL and non-Hodgkin lymphoma. The mechanism of action of lenalidomide varies depending on the pathology, and in the case of CLL, it appears to primarily act by restoring the damaged mechanisms of tumour immunosurveillance. This review discusses the potential mechanism of action and efficacy of lenalidomide, alone or in combination, in treatment of CLL and its toxic effects such as tumor lysis syndrome (TLS and tumor flare reaction (TFR, that make its management different from other hematologic malignancies.

    Full Text Available The chronic pain “three-step” OMS ladder is likely to be revised, in order to introduce a “fourth step” including clinical indications for the invasive analgesic procedures. The number of patients who undergo such procedures is likely to increase, as well as modern oncology and palliative medicine development. Most of invasive approaches include central (spinal neuromodulation and peripheral (gangliar neurolysis, percutaneous vertebral reduction techniques, as well as pharmacological (opioids and adiuvants, chemical (alcohol and physical (electrical stimulation, thermic neurolysis means. Rarely effective as unique therapies, invasive procedures have to be accurately patient-selected and considered supplementary to conservative approaches, in order to minimize the adverse events deriving from a long term opioid therapy. In the near future, the development of both pain science and biomedical technology will probably be accompanied by the improvement of the knowledge regarding the recourse to invasive analgesic procedures.

    Full Text Available Despite significant decreases in morbidity and mortality of cardiovascular diseases (CVD and cancers, morbidity and cost associated with chronic obstructive pulmonary disease (COPD continue to be increasing. Failure to improve disease outcomes has been related to the paucity of interventions improving survival. Insidious onset and slow progression halter research successes in developing disease-modifying therapies. In part, the difficulty in finding new therapies is because of the extreme heterogeneity within recognized COPD phenotypes. Novel biomarkers are necessary to help understand the natural history and pathogenesis of the different COPD subtypes. A more accurate phenotyping and the ability to assess the therapeutic response to new interventions and pharmaceutical agents may improve the statistical power of longitudinal clinical studies. In this study, we will review known candidate biomarkers for COPD, proposed pathways of pathogenesis, and future directions in the field.

  5. Embryonic development during chronic acceleration

    Smith, A. H.; Abbott, U. K.

    1982-01-01

    Experiments carried out on chicken eggs indicate that the embryo is affected during very early development, especially over the first four days, and during hatching. In the first four days, the brain develops as well as the anlage for all other organs. In addition, the heart commences to function and the extraembryonic membranes that compartmentalize the egg contents form. The latter require an appreciable extension and folding of tissue which may be disrupted by the mechanical load. Observations of embryonic abnormalities that occur during chronic acceleration suggest an inhibition of development of the axial skeleton, which is rarely seen otherwise, a general retardation of embryonic growth, and circulatory problems. The final stages of development (after 18 days) involve the uptake of fluids, the transition to aerial respiration, and the reorientation of the embryo into a normal hatching position. At 4 G mortality is very high during this period, with a majority of embryos failing to reorient into the normal hatching position.

    Chronic kidney disease (CKD) is a major health problem worldwide. Although relatively uncommon in children, it can be a devastating illness with many long-term consequences. CKD presents unique features in childhood and may be considered, at least in part, as a stand-alone nosologic entity. Moreover, some typical features of paediatric CKD, such as the disease aetiology or cardiovascular complications, will not only influence the child's health, but also have long-term impact on the life of the adult that they will become. In this review we will focus on the unique issues of paediatric CKD, in terms of aetiology, clinical features and treatment. In addition, we will discuss factors related to CKD that start during childhood and require appropriate treatments in order to optimize health outcomes and transition to nephrologist management in adult life.

    Abdominal pain is a major clinical problem in patients with chronic pancreatitis.The cause of pain is usually multifactorial with a complex interplay of factors contributing to a varying degree to the pain in an individual patient and,therefore,a rigid standardized approach for pain control tends to lead to suboptimal results.Pain management usually proceeds in a stepwise approach beginning with general lifestyle recommendations,low fat diet,alcohol and smoking cessation are encouraged.Analgesics alone are needed in almost all patients.Maneuvers aimed at suppression of pancreatic secretion are routinely tried.Patients with ongoing symptoms may be candidates for more invasive options such as endoscopic therapy,and resective or drainage surgery.The role of pain modifying agents (antidepressants,gabapentin,peregabalin),celiac plexus block,antioxidants,octreotide and total pancreatectomy with islet cell auto transplantation remains to be determined.

    Full Text Available Background: In 1769, William Cullen introduced the word "urticaria" (transient edematous papules, plaque with itching. Urticaria affects 15-25% of people at least once in their life time. It is a clinical reaction pattern triggered by many factors causing the liberation of vasoactive substances such as histamine, prostaglandins and kinins. Urticaria is classified according to its duration into acute (< 6 weeks duration and chronic (>6 weeks duration. Various clinical investigations may be initiated to diagnosis the cause. Aims: To evaluate the types of chronic urticaria with reference to etiology from history and investigations . Materials and Methods: A total of 150 patients with chronic urticaria of more than six weeks were studied. Autologous serum skin test (ASST was performed after physical urticarias were excluded. Standard batteries of tests were performed after ASST in all patients; and other specific investigations were done where necessary. Skin prick test was done in idiopathic urticaria. Results: The study sample consisted of 62 male and 88 female patients with a mean age of 21-40 years. About 50% of patients showed an ASST positive reaction, 3.9% were positive for antinuclear antibody (ANA, IgE titer was elevated in 37%, H. pylori antibodies was positive in 26.7%. Thyroid antibodies were positive in 6.2%.

    Chronic pancreatitis is defined as a continuous inflammatory pancreatic disease, one characterized by irreversible morphological changes, often associates with pain and sometimes with the loss of endocrine and exocrine function. As a histological confirmation of chronic pancreatitis is often unavailable, the diagnosis is traditionally based on imaging methods such as computerized tomography (CT) or endoscopic retrograde cholangiopancreatography (ERCP), and recently magnetic resonance cholangiopancreatography (MRCP) as a noninvasive alternative to ERCP. Developments in the classification system of CP include the Marseille classification of 1963 which offered histopathologic criteria for CP, the Cambridge classification of 1984 which introduced imaging features of computed tomography (CT), transabdominal ultrasound (TUS) and endoscopic retrograde cholangiopancreatography (ERCP) for classification of CP as well as Rosemont classification system of 2007 which presented the endoscopic ultrasonography diagnosis of CP. Endoscopic ultra-sonography (EUS) was first introduced as a diagnostic method for evaluation of pancreatic disease in 1986. It has experienced significant improvements since then and allowed for an alternative approach in diagnosing patients with pancreatic diseases. In patients with suspected pancreatic masses EUS-guided fine needle aspiration (EUS-FNA) is the best method for obtaining tissue diagnosis and differentiating CP from pancreatic carcinoma. The recent studies indicate that EUS is the method of choice when compared with other imaging methods such as ERCP because it frequently provides more accurate diagnostics. The aim of this review is to discuss the findings in endoscopic diagnostics up to the present moment and to indicate advantages, limitations and possible complications along with the current recommendations in CP diagnostics.

    2007-01-01

    AIM: To assess the prevalence of bowel dysfunction in hemiplegic patients, and its relationship with the site of neurological lesion, physical immobilization and pharmacotherapy.METHODS: Ninety consecutive hemiplegic patients and 81 consecutive orthopedic patients were investigated during physical motor rehabilitation in the same period, in the same center and on the same diet. All subjects were interviewed ≥ 3 mo after injury using a questionnaire inquiring about bowel habits before injury and at the time of the interview. Patients' mobility was evaluated by the Adapted Patient Evaluation Conference System. Drugs considered for the analysis were nitrates, angiogenic converting enzyme (ACE) inhibitors,calcium antagonists, anticoagulants, antithrombotics,antidepressants, anti-epileptics.RESULTS: Mobility scores were similar in the two groups. De novo constipation (OR = 5.36) was a frequent outcome of the neurological accident.Hemiplegics showed an increased risk of straining at stool (OR: 4.33), reduced call to evacuate (OR: 4.13),sensation of incomplete evacuation (OR: 3.69), use of laxatives (OR: 3.75). Logistic regression model showed that constipation was significantly and independently associated with hemiplegia. A positive association was found between constipation and use of nitrates and antithrombotics in both groups. Constipation was not related to the site of brain injury.CONCLUSION: Chronic constipation is a possible outcome of cerebrovascular accidents occurring in 30% of neurologically stabilized hemiplegic patients.Its onset after a cerebrovascular accident appears to be independent from the injured brain hemisphere,and unrelated to physical inactivity. Pharmacological treatment with nitrates and antithrombotics may represent an independent risk factor for developing chronic constipation.

  11. Chronic Intestinal Pseudo-Obstruction.

    2005-02-01

    Chronic intestinal pseudo-obstruction (CIP) is a gastrointestinal motility disorder characterized by chronic symptoms and signs of bowel obstruction in the absence of a fixed, lumen-occluding lesion. Radiographic findings consist of dilated bowel with air-fluid levels. Pseudo-obstruction is an uncommon condition and can result from primary or secondary causes. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. The principles of management of patients with CIP involve 1) establishing a correct clinical diagnosis and excluding mechanical obstruction; 2) differentiating between idiopathic and secondary forms; 3) performing a symptomatic and physiologic assessment of the parts of the gastrointestinal (GI) tract involved by manometric and whole gut transit scintigraphic studies; 4) careful assessment of nutritional status of the patient; and 5) developing a therapeutic plan addressing the patient's symptoms and nutritional status. Treatment of CIP includes frequent small meals with a low-fat, low-fiber diet, liquid nutritional supplements may be needed; prokinetic agents such as metoclopramide may help to reduce upper GI symptoms. Trials of drugs such as erythromycin, domperidone, cisapride, and tegaserod may be considered if there is no response. Subcutaneous octreotide may be helpful to improve small bowel dysmotility especially in patients with scleroderma. In patients with symptoms suggestive of bacterial overgrowth, courses of antibiotics such as metronidazole, ciprofloxacin, and doxycycline may be needed. Nutritional assessment and support is an important aspect of management. Enteral nutrition is usually preferred. In carefully selected patients, feeding jejunostomy with or without decompression gastrostomy may be tried. Long term parenteral nutrition should be reserved for patients who can not tolerate enteral nutrition. Complications associated with total parenteral nutrition include

    Acute kidney injury (AKI),defined as an abrupt increase in the serum creatinine level by at least 0.3 mg/dL,occurs in about 20% of patients hospitalized for decompensating liver cirrhosis.Patients with cirrhosis are susceptible to developing AKI because of the progressive vasodilatory state,reduced effective blood volume and stimulation of vasoconstrictor hormones.The most common causes of AKI in cirrhosis are pre-renal azotemia,hepatorenal syndrome and acute tubular necrosis.Differential diagnosis is based on analysis of circumstances of AKI development,natriuresis,urine osmolality,response to withdrawal of diuretics and volume repletion,and rarely on renal biopsy.Chronic glomeruIonephritis and obstructive uropathy are rare causes of azotemia in cirrhotic patients.AKI is one of the last events in the natural history of chronic liver disease,therefore,such patients should have an expedited referral for liver transplantation.Hepatorenal syndrome (HRS) is initiated by progressive portal hypertension,and may be prematurely triggered by bacterial infections,nonbacterial systemic inflammatory reactions,excessive diuresis,gastrointestinal hemorrhage,diarrhea or nephrotoxic agents.Each type of renal disease has a specific treatment approach ranging from repletion of the vascular system to renal replacement therapy.The treatment of choice in type 1 hepatorenal syndrome is a combination of vasoconstrictor with albumin infusion,which is effective in about 50% of patients.The second-line treatment of HRS involves a transjugular intrahepatic portosystemic shunt,renal vasoprotection or systems of artificial liver support.

    The comorbidity integrated by chronic pain and depression is very common. The somatoform depressive symptoms appear often as diferent types of pain. Amon them premenstrual pain and fibromialgia are some of the most important clinical pictures. Chronic pain leads to depression as a consequence of these three kinds of factors: biomedical, psychosocial (passive attitude, disability) and pharmacological agents. Copping and acceptance of chronic pain is associated with lower pain intensity, less depression and less psychosocial disability. The appropriate use of analgesics in the management of chronic pain demands individualization. Several antidepressants have possitive effects on pain syndrom. Depression is underrecognized ad undertreated above all in patients with chronic pain. In order screening the depression seven ways are described here: personal and family history, type of the personality, clinic and evolutive aspects of somatoform symptom, search of other depressive symptoms and positive therapeutic effect determinated by an antidepressant.

    2008-01-01

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    The baroque deity Chronos symbolizes much of what we intuitively connect with "chronic", but it must not obscure our view of the diversity of chronic diseases. Common to all forms is a prognostic implication: a chronic disease and all associated burden will accompany the patient for the rest of his/her life. Chronic diseases are in general multifocal disorders simultaneously affecting biological, psychic, and social equilibria. This requires systematic problem-screening and -assessment, including possible comorbidities. Comorbidity in a strict sense should be distinguished from risk factors, implications, complications, and consequences of the index disorder of interest. The assessment is usually followed by the shared identification of therapeutic goals and indications. In chronic disorders, a wide spectrum of diagnostic and therapeutic approaches, methods, and professions becomes relevant. PMID:21246322

    HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

    2014-12-01

    Full Text Available Chronic pancreatitis is characterised by progressive and irreversible damage of the pancreatic parenchyma and ductal system, which leads to chronic pain, loss of endocrine and exocrine functions. Clinically, pancreatic exocrine insufficiency becomes apparent only after 90% of the parenchima has been lost. Despite the simple definition, diagnosing chronic pancreatitis remains a challenge, especially for early stage disease. Because pancreatic function tests can be normal until late stages and have significant limitations, there is an incresing interest in the role of imaging techniques for the diagnosis of chronic pancreatitis. In this article we review the utility and accuracy of different imaging methods in the diagnosis of chronic pancreatitis, focusing on the role of advanced imaging (magnetic resonance imaging, endoscopic retrograde cholangiopancreatography and endoscopic ultrasound.

    Full Text Available Authors describe genitourinary changes in male hamsters infected and reinfected with Trypanosoma cruzi. Changes in genital organs have been described in human and in experimental chagasic infection. Genital dysfunctions in chronic chagasic patients affect ejaculation, libido and sexual potency, and testis biopsies may show arrested maturation of germ cells, oligozoospermia and azoospermia. Sixty-five male hamsters were inoculated and reinoculated with 2x10³ trypomastigotes of T. cruzi VIC strain, and 22 non-infected animals constituted the control group. Animals were necropsied and fragments from testis, epididymis, seminal vesicle and bladder were collected and stained with hematoxylin-eosin. Peroxidase anti-peroxidase procedure was utilized to detect tissue parasitism. T. cruzi nests were found in testis, epididymis and seminal vesicle of these hamsters. Such parasitism plays a role in the origin of genital lesions observed in humans and laboratory animals during chronic chagasic infection.

  1. Chronic pain after open inguinal hernia repair.

    Following the widespread use of mesh repairs, recurrence rates after inguinal hernia surgery have become acceptable and focus has shifted from recurrence to chronic pain. Although pain can be controlled with analgesics, chronic postsurgical pain is a major clinical problem, which can significantly influence the patient's quality of life. The rate of chronic pain after inguinal hernia mesh repair can reach 51.6%. The reasons for posthernioplasty chronic pain are often unclear. It has been linked to nerve injury and nerve entrapment, but there is also association between the rate of chronic pain and the type of mesh used for hernia repair. As there are >160 meshes available in the market, it is difficult to choose a mesh whose usage would result in the best outcome. Different mesh characteristics have been studied, among them weight of mesh has probably gained the most attention. The choice of adequate therapy for chronic groin pain after inguinal hernia repair is controversial. The European Hernia Society recommends that a multidisciplinary approach at a pain clinic should be considered for the treatment of chronic postoperative pain. Although surgical treatment of chronic posthernioplasty pain is limited because of the lack of relevant research data, resection of entrapped nerves, mesh removal in the case of mesh related pain or removal of fixation sutures can be beneficial for the patient with severe pain after inguinal hernia surgery. One drawback of published studies is the lack of consensus over definition of chronic pain, which makes it complicated to compare the results of different studies and to conduct meta-analyses and systematic reviews. Therefore, a uniform definition of chronic pain and its best assessment methods should be developed in order to conduct top quality multicenter randomized trials. Further research to develop meshes with optimal parameters is of vital importance and should be encouraged. PMID:26567717

Chronic groin pain is one of the most significant complications following inguinal hernia repair, and majority of chronic pain has been attributed to ilioinguinal nerve entrapment. Various other factors are involved in development of chronic pain. MATERIAL AND METHODS: Patients undergoing elective inguinal hernioplasty in Victoria hospital from November2011 to May 2013 were included in the study. A total of 227 patients met the inclusion criteria and were available for follow up at end of six months. A detailed preoperative, intraoperative and post-operative details of cases were recorded according to proforma. The postoperative pain and pain at two, seven days and at end of six months were recorded on a VAS scale. RESULTS: Chronic pain at six month follow up was present in 89 patients constituting 39.4% of all patients undergoing hernia repair. It was seen that 26.9% without preoperative pain developed chronic pain whereas 76.7 % of patients with preoperative pain developed chronic pain. Patients with significant preoperative pain had higher chances of developing chronic pain (p<.0001. Preemptive analgesia failed to show statistical significance in development of chronic pain (p=0.079. Nerve injury were present in 22 of cases it was found that nerve injury significantly affected development of chronic pain (p=0.001.Post-operative infiltration of local anesthesia was practiced in 16.3 % of cases and it was found that local infiltration at incision site significantly reduced incidence of chronic pain (p=0.001.Postoperative complications in the form of hematoma, seroma or infection was present in 8.5 % of cases. It was found that post-operative complication not only increased early post-operative pain

    Full Text Available Introduction: The affective component of pain incorporates various emotions, primarily negative in quality. A great emphasis has been traditionally given to the role of depression and anxiety in chronic pain. More recently, the focus has been directed towards hostility and anger, as fundamental components of the emotional experience of chronic pain. Objective: The aim of this article is to present a literature’s review about the association between chronic pain, anger and hostility. Discussion: Patients with several chronic disorders are characterized by high levels of trait anger and hostility. On the other hand, the manner in which angry feelings are typically handled (anger management style, especially the marked tendency to suppress or express angry feelings, is a particularly important determinant of the chronic pain severity. Conclusion: Hostility and anger are involved in the development, maintenance and treatment of chronic pain. Further research is needed to clarify its relationship with chronic pain and to evaluate the effects of anger management on treatment outcomes.

    Chronic kidney disease (CKD) is a frequent complication of HIV infection, occurring in 3.5 - 48.5%, and occurs as a complication of HIV infection, other co-morbid disease and infections and as a consequence of therapy of HIV infection and its complications. The classic involvement of the kidney by HIV infection is HIV-associated nephropathy (HIVAN), occurring typically in young adults of African ancestry with advanced HIV disease in association with APOL1 high-risk variants. HIV-immune complex disease is the second most common diagnosis obtained from biopsies of patients with HIV-CKD. CKD is mediated by factors related to the virus, host genetic predisposition and environmental factors. The host response to HIV infection may influence disease phenotype through activation of cytokine pathways. With the introduction of antiretroviral therapy (ART), there has been a decline in the incidence of HIVAN, with an increasing prevalence of focal segmental glomerulosclerosis. Several studies have demonstrated the overall improvement in kidney function when initiating ART for HIV CKD. Progression to end stage kidney disease has been reported to be more likely when high grade proteinuria, severely reduced eGFR, hepatitis B and/C co-infection, diabetes mellitus, extensive glomerulosclerosis, and chronic interstitial fibrosis are present. Improved renal survival is associated with use of renin angiotensin system blockers and viral suppression. Many antiretroviral medications are partially or completely eliminated by the kidney and require dose adjustment in CKD. Certain drug classes, such as the protease inhibitors and the non-nucleoside reverse transcriptase inhibitors, are metabolized by the liver and do not require dose adjustment. HIV-infected patients requiring either hemo- or peritoneal dialysis, who are stable on ART, are achieving survival rates comparable to those of dialysis patients without HIV infection. Kidney transplantation has been performed successfully in HIV

    Full Text Available Introduction Most studies that have evaluated the stomachs of patients with Chagas disease were performed before the discovery of Helicobacter pylori and used no control groups. This study compared the gastric features of chagasic and non-chagasic patients and assessed whether gastritis could be associated with Chagas disease. Methods Gastric biopsy samples were taken from patients who underwent endoscopy for histological analysis according to the Updated Sydney System. H. pylori infection was assessed by histology, 16S ribosomal ribonucleic acid (rRNA polymerase chain reaction (PCR, serology and the 13C-urea breath test. Patients were considered H. pylori-negative when all of these diagnostic tests were negative. Clinical and socio-demographic data were obtained by reviewing medical records and using a questionnaire. Results The prevalence of H. pylori infection (70.3% versus 71.7% and chronic gastritis (92.2% versus 85% was similar in the chagasic and non-chagasic groups, respectively; such as peptic ulcer, atrophy and intestinal metaplasia. Gastritis was associated with H. pylori infection independent of Chagas disease in a log-binomial regression model. However, the chagasic H. pylori-negative patients showed a significantly higher grade of mononuclear (in the corpus and polymorphonuclear (PMN (in the antrum cell infiltration. Additionally, the patients with the digestive form of Chagas disease showed a significantly lower prevalence of corpus atrophy than those with other clinical forms. Conclusions The prevalence of H. pylori infection and of gastric histological and endoscopic features was similar among the chagasic and non-chagasic patients. Additionally, this is the first controlled study to demonstrate that H. pylori is the major cause of gastritis in patients with Chagas disease.

    An inefficient cellular immune response likely leads to chronic hepatitis C virus (HCV) infection. Resolution of chronic HCV infection in the absence of treatment is a rare occurrence. We report the case of a 39-year old white male with a 17-year history of chronic HCV infection, who eradicated HCV following a serious illness due to co-infection with Babesia (babesiosis), Borriela Borgdorferi (Lyme disease) and Ehrlichia (human granulocytic ehrlichiosis). We hypothesize that the cellular immune response mounted by this patient in response to his infection with all three agents but in particular Babesia was sufficient to eradicate HCV.

    Syndromes characterized by persistent fatigue, musculoskeletal pain, sleep disturbance, and subjective cognitive impairment have been common problems in clinical practice for decades. The chronic fatigue syndrome case definition was created to standardize the patient population in research studies and to foster a systematic and comprehensive approach to the attempt to define the etiology and pathophysiology of these syndromes. The pathogenesis of chronic fatigue syndrome remains unknown, though it does appear to be associated with subtle neuroendocrine and immunologic abnormalities. Treatment of chronic fatigue syndrome is empirical. Significant palliation is often possible, though treatment success requires skillful practice of the art of medicine. PMID:9608620

    Full Text Available Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical properties of the respiratory system and its component parts are studied by determining the corresponding volume-pressure (P-V relationships. The consequences of the inflammatory response on the lung structure and function are depicted on the volume-pressure relationships.

A case control study was carried out in 30 subjects with chronic periodontitis aged 30 - 65 ye ars (group II and age matched with 30 control subjects (group I. Salivary and serum malondialdehyde, which is a marker of lipid peroxidation, was estimated in the cases and controls. Salivary MDA was elevated (p<0.001 in patients with chronic periodonti tis there was no change in serum MDA levels when compared with normal controls. Increased levels in MDA may be closely associated with periodontal disease and salivary estimation may provide advantage in pathogenesis of the periodontal disease. .

    Chronic migraine is defined as having more than 15 headache days in a month, half of these showing migraine features, for at least 3 months. It is a chronic painful syndrome with aspects such as psychiatric comorbid, decreased quality of life, and environmental and intrinsic psychological factors that make face-to-face treatment difficult. Children and adolescent migraine differ from adults as a result of growing brain and evolving disorder. In this paper, we will emphasize the definition, diagnosis, epidemiology, burden of life, and management of chronic migraine in children and adolescent.

    Chronic meningitis can be a diagnostic dilemma for even the most experienced clinician. Many times, the differential diagnosis is broad and encompasses autoimmune, neoplastic, and infectious etiologies. This review will focus on a general approach to chronic meningitis to simplify the diagnostic challenges many clinicians face. The article will also review the most common etiologies of chronic meningitis in some detail including clinical presentation, diagnostic testing, treatment, and outcomes. By using a case-based approach, we will focus on the key elements of clinical presentation and laboratory analysis that will yield the most rapid and accurate diagnosis in these complicated cases.

    Full Text Available Gastrointestinal (GI bleeding is more common in patients with chronic kidney disease and is associated with higher mortality than in the general population. Blood losses in this patient population can be quite severe at times and it is important to differentiate anemia of chronic diseases from anemia due to GI bleeding. We review the literature on common causes of lower gastrointestinal bleeding (LGI in chronic kidney disease (CKD and end-stage renal disease (ESRD patients. We suggest an approach to diagnosis and management of this problem.

    Chronic methylmercurialism was produced in a horse given 10 g methylmercury chloride over 10 weeks. Neurological signs, particularly proprioceptive disturbances, were apparent by the final week of dosing and became more severe thereafter. An exudative dermatitis, a reluctance to move, weight loss, reduced appetite and dullness were among the earlier clinical signs, and renal changes characterized by a steadily increasing BUN and glucosuria were detected later. Pathological lesions were confined to the kidneys and the nervous system. There was mild neuronal degeneration in the cerebral cortex and in the cerebellar cortex, axonal demyelination in the dorsal columns of the spinal cord and extensive degeneration of ganglion cells in the dorsal root ganglia. The blood organic mercury level, which had plateaued in the second month, increased rapidly in the last weeks of dosing with a sharp rise terminally. This pattern was repeated for the much lower inorganic mercury levels except for a terminal decrease. The proportion of inorganic mercury was five times greater in the dorsal root ganglia than elsewhere in the CNS, although total mercury levels were similar. Highest tissue mercury levels were found in the liver and kidneys, over 50% being in the form of inorganic mercury. As dealkylation of the methylmercury appeared to be more efficient in the dorsal root ganglia and the kidneys, inorganic mercury derived therefrom may have been responsible for some of the clinical and pathological features of this intoxication in the horse. 21 references, 6 figures, 2 tables.

  20. Caregiver Burden in Chronic Diseases

    2011-09-01

    Full Text Available Duration of human life has been substantially increased in the last fifty years. Survivals of diseases have been prolonged through the advances in medicine. Together with these gratifying consequences, there appeared novel difficulties to cope with. Furthermore developments including globalization, industrialization and transition from rural to urban life occurred during the last century; so family units became smaller and numbers of members on employment in family units increased. As a result numbers of family members to undertake the responsibility of care decreased. As a concept, caregiver burden expresses physical, psychosocial and financial reactions during the course of care providing. Distinct factors including structures of social, cultural and family units and health care systems may affect conditions of care. Caregiver’s age, gender, ethnicity, education, relationship with the patient, attitude towards providing care, financial situation, coping abilities, her own health, beliefs, social support and cultural pattern are the personal factors that are related to perception of caregiver burden. Burden of care giving is geared to differential aspects of care needs. For instance care needs of physically disabled and medical care requiring patients with spinal cord injuries may differ from care needs of chronic psychiatric disorders, demented patients in advanced age of their lives or cancer patients in terminal periods. Strain due to care giving may differ as a result of properties of care demands. It is aimed to review the burden of caregivers in different medical and psychiatric care requiring conditions and to introduce differential aspects of caregiver burden in these different conditions.

  1. Gene Polymorphisms in Chronic Periodontitis

    Full Text Available We aimed to conduct a review of the literature for gene polymorphisms associated with chronic periodontitis (CP susceptibility. A comprehensive search of the literature in English was performed using the keywords: periodontitis, periodontal disease, combined with the words genes, mutation, or polymorphism. Candidate gene polymorphism studies with a case-control design and reported genotype frequencies in CP patients were searched and reviewed. There is growing evidence that polymorphisms in the IL1, IL6, IL10, vitamin D receptor, and CD14 genes may be associated with CP in certain populations. However, carriage rates of the rare (-allele of any polymorphism varied considerably among studies and most of the studies appeared under-powered and did not correct for other risk factors. Larger cohorts, well-defined phenotypes, control for other risk factors, and analysis of multiple genes and polymorphisms within the same pathway are needed to get a more comprehensive insight into the contribution of gene polymorphisms in CP.

Direct markers (mainly blood or serum and urine ethanol, ethylglucuronide, ethyl sulfate, and phosphatidylethanol directly track the intake of alcohol and vary in their sensitivity and kinetics of appearance and clearance. Indirect markers (mean corpuscular volume,γ-glutamyl transferase, alanine aminotransferase and aspartate aminotransferase, and carbohydrate-deficient transferrin are biological parameters that are influenced by a steady and significant alcohol intake. We discuss the values of these tests and the relevance of their prescriptions for the clinical evaluation of heavy drinking. We indicate, when known, the pathophysiological mechanism of their elevations. We also discuss the amount and time of alcohol consumption required to give a positive result and the duration of abstinence required for the return to normal values. The forensic use of these biomarkers will not be considered in this review.Keywords: alcoholism, biomarker, CDT, relapse, alcohol-induced liver disease

    2014-06-01

    Full Text Available The pain associated with spondyloarthritis (SpA can be intense, persistent and disabling. It frequently has a multifactorial, simultaneously central and peripheral origin, and may be due to currently active inflammation, or joint damage and tissue destruction arising from a previous inflammatory condition. Inflammatory pain symptoms can be reduced by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in the mechanisms that regulate central pain, as in the case of the chronic widespread pain (CWP that characterises fibromyalgia (FM. The importance of distinguishing SpA and FM is underlined by the fact that SpA is currently treated with costly drugs such as tumour necrosis factor (TNF inhibitors, and direct costs are higher in patients with concomitant CWP or FM than in those with FM or SpA alone. Optimal treatment needs to take into account symptoms such as fatigue, mood, sleep, and the overall quality of life, and is based on the use of tricyclic antidepressants or selective serotonin reuptake inhibitors such as fluoxetine, rather than adjustments in the dose of anti-TNF agents or disease-modifying drugs.

    Full Text Available BACKGROUND Chronic Heart Failure (CHF represents worldwide a clinical condition with increasing prevalence, high social, economical and epidemiological impact. Even if new pharmacological and non-pharmacological approachs have been recently used, mortality remains high in general population and quality of life is poor in these patients. DISCUSSION The association between CHF and sleep disorders is frequent but still undervalued: sleep apnoeas in CHF produce negative effects on cardiovascular system and an aggravation of prognosis. CPAP (Continuous Positive Airway Pressure is commonly used to treat sleep apnoeas in patients without cardiac involvement and it is also used in first line treatment of acute cardiogenic pulmonary oedema thanks to its hemodynamic and ventilatory effects. The addition of nightly CPAP to standard aggressive medical therapy in patients with CHF and sleep apnoeas reduces the number of apnoeas, reduces the blood pressure, and the respiratory and cardiac rate, reduces the activation of sympathetic nervous system, the left ventricular volume and the hospitalization rate; besides CPAP increases the left ventricular ejection fraction, amd the oxygenation, it improves quality of life, tolerance to exercise and seems to reduce mortality in patients with a higher apnoeas suppression. CONCLUSIONS These implications suggest to investigate sleep apnoeas in patients with CHF in order to consider a possible treatment with CPAP. Further studies need to be developed to confirm the use of CPAP in patients with CHF without sleep disorders.

    2006-01-01

    Chronic non-communicable diseases (NCD) account for almost 60% of global mortality, and 80% of deaths from NCD occur in low- and middle-income countries. One quarter of these deaths--almost 9 million in 2005--are in men and women aged globalisation of the food, tobacco and alcohol industries. Because NCD have a major impact on men and women of working age and their elderly dependents, they result in lost income, lost opportunities for investment, and overall lower levels of economic development. Reductions in the incidences of many NCD and their complications are, however, already possible. Up to 80% of all cases of cardiovascular disease or type-2 diabetes and 40% of all cases of cancer, for example, are probably preventable based on current knowledge. In addition, highly cost-effective measures exist for the prevention of some of the complications of established cardiovascular disease and diabetes. Achieving these gains will require a broad range of integrated, population-based interventions as well as measures focused on the individuals at high risk. At present, the international-assistance community provides scant resources for the control of NCD in poor countries, partly, at least, because NCD continue to be wrongly perceived as predominantly diseases of the better off. As urbanization continues apace and populations age, investment in the prevention and control of NCD in low-and middle-income countries can no longer be ignored. PMID:16899148

    Full Text Available Chronic traumatic encephalopathy (CTE is a progressive neurodegenerative disease that is a long-term consequence of single or repetitive closed head injuries for which there is no treatment and no definitive pre-mortem diagnosis. It has been closely tied to athletes who participate in contact sports like boxing, American football, soccer, professional wrestling and hockey. Risk factors include head trauma, presence of ApoE3 or ApoE4 allele, military service, and old age. It is histologically identified by the presence of tau-immunoreactive NFTs and NTs with some cases having a TDP-43 proteinopathy or beta-amyloid plaques. It has an insidious clinical presentation that begins with cognitive and emotional disturbances and can progress to Parkinsonian symptoms. The exact mechanism for CTE has not been precisely defined however, research suggest it is due to an ongoing metabolic and immunologic cascade called immunoexcitiotoxicity. Prevention and education are currently the most compelling way to combat CTE and will be an emphasis of both physicians and athletes. Further research is needed to aid in pre-mortem diagnosis, therapies, and support for individuals and their families living with CTE.

    From 2001 to 2006, we performed a retrospective study of patients suffering from chronic unilateral or bilateral tinnitus that was previously ineffectively treated by oral drugs [betahistine (Betaserc), extract of Ginkgo biloba (EGb 761), tanakan (Tebokan), and cinnarizine-dimenhydrinate (Arlevert), singly or in combination]. We divided 150 tinnitus patients (80 men, 70 women) into seven treatment groups. Treatments consisted of application of intravenous pentoxifylline, lidocaine, or vinpocetine (Cavinton) and combination of these agents with physiotherapy and soft laser. Mean duration (+/- standard deviation) of tinnitus in these patients was 7.4 +/- 6.0 years; their mean age was 55.6 +/- 12.5 years. The aim of our study was to compare treatment modalities and define their effectiveness for tinnitus relief. The most effective treatment was defined as a combination of Cavinton and physiotherapy. We evaluated pure lidocaine infusion therapy as ineffective. None of the treatment modalities had an objective correlate of improvement, though improvement was reported by a visual analog scale.

    BACKGROUND: In contrast to the well-described 10% risk of chronic pain affecting daily activities after adult groin hernia repair, chronic pain after childhood groin hernia repair has never been investigated. Studies of other childhood surgery before the age of 3 months suggest a risk of increased...... pain responsiveness later in life, but its potential relationship to chronic pain in adult life is unknown. METHODS: This was a nationwide detailed questionnaire study of chronic groin pain in adults having surgery for a groin hernia repair before the age of 5 years (n = 1075). RESULTS: The response...... the age of 3 months (n = 122) did not report groin pain more often or with higher intensity than other patients did. CONCLUSIONS: Groin pain in adult patients operated on for a groin hernia in childhood is uncommon and usually mild and occurs in relation to physical activity. Operation before the age...

    2014-06-01

    Chronic spontaneous urticaria, also known as chronic idiopathic urticaria or simply chronic urticaria, is a common disorder that has a prevalence in the general population that ranges between 0.5% and 1%. This condition negatively affects the patient's quality of life and has considerable impact on direct and indirect health-related costs. Chronic urticaria is difficult to manage. Nonsedating H1 antihistamines are the first line of therapy, but fewer than 50% of patients experience relief at recommended dosages. Although guidelines call for increasing the dosage when response is inadequate, some patients still do not achieve adequate control of symptoms. New treatment alternatives, with proven efficacy under the standards of evidence-based medical practice, must therefore be developed.

    Full Text Available Chronic urticaria accounts for up to 75% of patients with urticaria attending dermatology clinics and can persist for many years. Chronic urticaria often causes significant quality of life issues due to pruritus and urticarial lesions resistant to treatment. Patients attending urticaria clinics have a similar impairment of quality of life as those with eczema or those with coronary disease awaiting by pass surgery. A good response to standard treatment with oral H1 receptor antagonists occurs in under 50%. Immunomodulatory or immunosuppression therapy might therefore required in patients with severe refractory chronic urticaria. But these treatments have too many adverse effects and difficulties in their using. In two current reports, three cases of severe chronic urticaria, unresponsive to conventional therapy, with a successful response to antidepressant mirtazapine were presented. Herein we present three cases responding oral mirtazapine, resistant combination therapies including antihistaminics, leucotrien antagonists and systemic corticosteroids. (Turkderm 2008; 42: 31-3

    Developments increasing our understanding of chronic urticaria have resulted in the simplification and improvement of available treatments. Currently, many treatments target mast cell mediators, but we can now disrupt mast cell activation with the anti-IgE antibody omalizumab, which has markedly advanced the treatment landscape for patients with difficult-to-treat urticaria. Current guidelines provide a framework for the management and treatment of patients with CU but, as each patient is different, knowledge and experience of specialist dermatologists and allergists are key to effective pharmacotherapy. This article reviews the different therapeutic options for patients with chronic spontaneous urticaria (also called chronic idiopathic urticaria) or chronic inducible urticaria and discusses management of special populations or special circumstances related to CU.

    The frequency and degree of circulatory insufficiency depending on the stage of the disease are analyzed in 404 patients with chronic glomerulonephritis and 145 patients with chronic pyelonephritis aged 15 to 74 years. When the renal function is still preserved different degrees of circulatory insufficiency are diagnosed in 29.4% of patients. Circulatory insufficiency complicates more often chronic glomerulonephritis than pyelonephritis and is more common in the aged. Latent cardiac insufficiency is more common. In the period of chronic renal insufficiency cardiac decompensation is seen in 78.1% of cases, its frequency is practically the same in glomerulonephritis and pyelonephritis. The mechanisms of development of cardiac insufficiency and the principles of treatment depending on the functional state of the kidneys are discussed.

  9. Temperament vs. chronic fatigue in police officers

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Background: Chronic fatigue is a problem affecting a still growing number of people. Among them there are representatives of different professions who are forced to cope not only with occupational stress, but also with the problem of fatigue. The police is one of such occupational groups, in which exposure to stressful and often traumatic situations, contact with those who violate the law, shift work and contact with superiors can play a key role in the development of chronic fatigue. However, chronic fatigue, induced by the above mentioned factors, does not affect all police officers since its occurrence also depends on many personal traits, including temperament. Material and methods: We studied a group of 61 police officers of the Kuyavian-Pomeranian garrison. The study was conducted using the Buss and Plomin EAS (emotionality, activity, sociability Temperament Questionnaire, CIS-20R (community, innovation, survey Questionnaire, developed by Vercoulen et al. and a questionnaire on socio-demographic data. Results: The results indicated the relationship between chronic fatigue and emotionality. Statistical analyses showed a negative correlation between the nature of emotional components, distress, fear, anger, and the general rate of chronic fatigue. There was no statistically significant correlation between age, and service experience and the level of chronic fatigue. Conclusions: The results indicate that the officers of the study group show dramatically high levels of chronic fatigue. The results also revealed that temperament characteristics, such as sociability and activity, reported in the literature as factors reducing fatigue and stress, did not show relevance to chronic fatigue in the study group.

Among the control group which com-prised of 100 patients, 20% had dental caries. There was thus no increased incidence of dental caries among patients with urticaria. Only 2 patients had remission of urticaria following treat-ment of caries. Dental caries therefore is probably not a cause of chronic urticaria.

    Full Text Available Introduction: The Chronicity Prevention and Care Programme set up by the Health Plan for Catalonia 2011–2015 has been an outstanding and excellent opportunity to create a new integrated care model in Catalonia. People with chronic conditions require major changes and transformation within the current health and social system. The new and gradual context of ageing, increase in the number of chronic diseases and the current fragmented system requires this transformation to be implemented. Method: The Chronicity Prevention and Care Programme aims to implement actions which drive the current system towards a new scenario where organisations and professionals must work collaboratively. New tools should facilitate this new context- or work-like integrated health information systems, an integrative financing and commissioning scheme and provide a new approach to virtual care by substituting traditional face-to-face care with transfer and shared responsibilities between patients, citizens and health care professionals. Results: It has been observed some impact reducing the rate of emergency admissions and readmission related to chronic conditions and better outcome related to better chronic disease control. Some initiative like the Catalan Expert Patient Program has obtained good results and an appropriate service utilization. Discussion: The implementation of a Chronic Care Program show good results but it is expected that the new integrated health and social care agenda could provoke a real change and transformation. Some of the results related to better health outcomes and a decrease in avoidable hospital admissions related to chronic conditions confirm we are on the right track to make our health and social system more sustainable for the decades to come.

  15. Chronic eosinophilic pneumonia: CT findings

    International Nuclear Information System (INIS)

    Objective: To assess the usefulness of computerized tomography (CT) in the diagnosis of chronic eosinophilic pneumonia. Material and Methods: A double helical CT was performed in 6 patients referred to our center because of a chest X-ray with pulmonary infiltrates. Clinical presentation was cough, fever and eosinophilia in peripheral blood. Patients' age ranged from 25 to 55 years; 4 were women and 2 were men, one of the latter had a history of bronchial asthma. All patients received treatment with corticosteroids, with remission of the clinical and radiological parameters. Three patients underwent a control CT. Results: Findings consisted in focal parenchymal alterations, with areas of pulmonary consolidation and areas of 'ground glass' appearance; both patterns coexisted in certain areas. In 3 cases the lesions extended from the apices to the pulmonary bases, with predominance of the upper and middle fields. In 1 patient, there was frank predominance in the left hemi thorax. In another patient, who had a history of asthma, there were signs of pulmonary hyperinflation, with diffuse thickening of the bronchial walls, added to the previously mentioned findings, which involved the entire lung. In the mediastinum, 1 patient had lymph nodes larger than 1 cm, 3 had lymph nodes that were not enlarged but were more numerous than usual, and in the remaining patients no lymph nodes were found. The control CT's showed almost total resolution of the pulmonary infiltrates. Conclusion: The combination of eosinophilia and characteristic pulmonary infiltrates with a likely clinical presentation, associated with an optimal response to treatment with corticosteroids allows to make a reliable diagnosis and avoids the need for a pulmonary biopsy.

    Science.gov (United States)

    Meola, Mario; Samoni, Sara; Petrucci, Ilaria

    2016-01-01

    Chronic kidney disease (CKD) diagnosis and staging are based on estimated or calculated glomerular filtration rate (GFR), urinalysis and kidney structure at renal imaging techniques. Ultrasound (US) has a key role in evaluating both morphological changes (by means of B-Mode) and patterns of vascularization (by means of color-Doppler and contrast-enhanced US), thus contributing to CKD diagnosis and to the follow-up of its progression. In CKD, conventional US allows measuring longitudinal diameter and cortical thickness and evaluating renal echogenicity and urinary tract status. Maximum renal length is usually considered a morphological marker of CKD, as it decreases contemporarily to GFR, and should be systematically recorded in US reports. More recently, it has been found to be a significant correlation of both renal longitudinal diameter and cortical thickness with renal function. Conventional US should be integrated by color Doppler, which shows parenchymal perfusion and patency of veins and arteries, and by spectral Doppler, which is crucial for the diagnosis of renal artery stenosis and provides important information about intrarenal microcirculation. Different values of renal resistive indexes (RIs) have been associated with different primary diseases, as they reflect vascular compliance. Since RIs significantly correlate with renal function, they have been proposed to be independent risk factors for CKD progression, besides proteinuria, low GFR and arterial hypertension. Despite several new applications, US and color Doppler contribute to a definite diagnosis in <50% of cases of CKD, because of the lack of specific US patterns, especially in cases of advanced CKD. However, US is useful to evaluate CKD progression and to screen patients at risk for CKD. The indications and the recommended frequency of color Doppler US could differ in each case and the follow-up should be tailored. PMID:27170301

    BACKGROUND:Treatment of chronic pancreatitis (CP) is a challenging condition for surgeons. During the last decades, increasing knowledge about pathophysiology of CP, improved results of major pancreatic resections, and integration of sophisticated diagnostic methods in clinical practice have resulted in signiifcant changes in surgery for CP. DATA SOURCES:To detail the indications for CP surgery, the surgical procedures, and outcome, a Pubmed database search was performed. The abstracts of searched articles about surgical management of CP were reviewed. The articles could be identiifed and further scrutinized. Further references were extracted by cross-referencing. RESULTS: Main indications of CP for surgery are intractable pain, suspicion of malignancy, and involvement of adjacent organs. The goal of surgical treatment is to improve the quality of life of patients. The surgical approach to CP should be individualized according to pancreatic anatomy, pain characteristics, baseline exocrine and endocrine function, and medical co-morbidity. The approach usually involves pancreatic duct drainage and resection including longitudinal pancreatojejunostomy, pancreatoduodenectomy (Whipple's procedure), pylorus-preserving pancreatoduodenectomy, distal pancreatectomy, total pancreatectomy, duodenum-preserving pancreatic head resection (Beger's procedure), and local resection of the pancreatic head with longitudinal pancreatojejunostomy (Frey's procedure). Non-pancreatic and endoscopic management of pain has also been advocated. CONCLUSIONS:Surgical procedures provide long-term pain relief, a good postoperative quality of life with preservation of endocrine and exocrine pancreatic function, and are associated with low early and late mortality and morbidity. In addition to available results from randomized controlled trials, new studies are needed to determine which procedure is the most effective for the management of patients with CP.

    Although it has become an accepted standard to acknowledge the patient as a full partner in health care decisions, replacing traditional authoritative relationships with those based on an emancipatory model, the experiences of persons living with chronic illness confirm that this paradigm shift is not yet apparent in many health care relationships. In this paper, the authors present a qualitative secondary analysis of combined data sets from their research into chronic illness experience with two quite different chronic diseases - Type I Diabetes (a socially legitimized chronic disease) and Environmental Sensitivities (a disease which is currently treated with considerable scepticism). Comparing the experiences of individuals with diseases that are quite differently socially constructed, it becomes possible to detect common underlying health professional values and attitudes that powerfully influence the experience of living with and negotiating health care for a chronic illness. In the discussion of findings from this study, the authors examine the implications of the spiral of behaviors that fuels mutual alienation in chronic illness care relationships if professionals are unable to value patient expertise.

  19. Nonspecificity of Chronic Soft Tissue Pain Syndromes

    Full Text Available Persistent (or chronic pain occurs with a prevalence of about 10% in the adult population, and chronic soft tissue pain is especially problematic. Criteria for diagnosis of these soft tissue pain disorders appear to suffer from specificity problems, even though they appear to be sensitive in distinguishing normal from soft tissue pain sufferers. A few decades ago the term 'neuraesthenia' was used as a diagnosis in individuals who now would probably be diagnosed as suffering from fibromyalgia, chronic fatigue and anxiety disorders with fatigue. Soft tissue pain provokes skepticism, especially among third-party payers, and controversy among clinicians. Recent epidemiological studies have demonstrated sex differences in the prevalence of widespread pain and multiple tender points, which are distributed variably throughout the adult population and tend to be correlated with subjective symptoms. Although there is a tendency for these syndromes to persist, follow-up studies show that they tend to vary in extent and sometimes show remissions over longer follow-up, casting doubt about the distinctions between chronic diffuse pains and localized chronic soft tissue pains. Because both accidents and soft tissue pains are relatively prevalent problems, the possibility of chance coincidence of accident and chronic soft tissue pain in an individual creates the need to be cautious in attributing these syndromes to specific accidents in medicolegal situations. At the same time, the available evidence does not support a generally dismissive attitude towards these patients.

    Chronic pain is a public health concern affecting 20-30% of the population of Western countries. Although there have been many scientific advances in the understanding of the neurophysiology of pain, precisely assessing and diagnosing a patient's chronic pain problem is not straightforward or well-defined. How chronic pain is conceptualized influences how pain is evaluated and the factors considered when making a chronic pain diagnosis. There is no one-to-one relationship between the amount or type of organic pathology and pain intensity, but instead, the chronic pain experience is shaped by a myriad of biomedical, psychosocial (e.g. patients' beliefs, expectations, and mood), and behavioural factors (e.g. context, responses by significant others). Assessing each of these three domains through a comprehensive evaluation of the person with chronic pain is essential for treatment decisions and to facilitate optimal outcomes. This evaluation should include a thorough patient history and medical evaluation and a brief screening interview where the patient's behaviour can be observed. Further assessment to address questions identified during the initial evaluation will guide decisions as to what additional assessments, if any, may be appropriate. Standardized self-reported instruments to evaluate the patient's pain intensity, functional abilities, beliefs and expectations, and emotional distress are available, and can be administered by the physician, or a referral for in depth evaluation can be made to assist in treatment planning.
