Guillain-Barré syndrome (GBS) is often preceded by an infectious disease. A case of GBS after hepatitis A in a pregnant woman is described. The patient was treated with intravenous immunoglobulin and had full recovery with no neurologic sequelae. She gave birth in term to a healthy baby. This is the first reported case in the English literature of a triple condition of hepatitis A, GBS, and pregnancy. 相似文献

Time, times and timing are key words in inflammatory bowel diseases (IBD). The leifmotif of this issue or World Journal of Gastroenterology is time. We have asked experts to review on the epidemiology of these diseases over time, the changes in innate immunity that could be present in the first time, and then the timing of key treatments. The correct time of using azathioprine, mercaptopurine, infliximab, cyclosporine and surgery are reviewed. We have chosen experts with not only great clinical expertise but also personal interest in clinical and basic investigation. Our goal in this monograph is to get an idea not only of the present but of the immediate future in some of the key management issues in IBD. To this end, we think that the authors are the most adequate. 相似文献

In the last few decades, neurobiological and human brain imaging research have greatly advanced our understanding of brain mechanisms that support perception and memory, as well as their function in daily activities. Knowledge of the neurobiological mechanisms behind the deafferentation of stomatognathic systems has also expanded greatly in recent decades. In particular, current studies reveal that the peripheral deafferentations of stomatognathic systems may be projected globally into the central nervous system (CNS) and become an associated critical factor in triggering and aggravating neurodegenerative diseases.This review explores basic neurobiological mechanisms associated with the deafferentation of stomatognathic systems. Further included is a discussion on tooth loss and other dental deafferentation (DD) mechanisms, with a focus on dental and masticatory apparatuses associated with brain functions and which may underlie the changes observed in the aging brain. A new hypothesis is presented where DD and changes in the functionality of teeth and the masticatory apparatus may cause brain damage as a result of altered cerebral circulation and dysfunctional homeostasis. Furthermore, multiple recurrent reorganizations of the brain may be a triggering or contributing risk factor in the onset and progression of neurodegenerative conditions such as Alzheimer's disease (AD). A growing understanding of the association between DD and brain aging may lead to solutions in treating and preventing cognitive decline and neurodegenerative diseases. 相似文献

AIM: To compare the effects of Helicobacter pylori ( H pylori) infection on gastropathy between Indonesian and Japanese patients.METHODS: Biopsy specimens were obtained during upper gastrointestinal endoscopy from 167 subjects (125 Indonesians and 42 Japanese) with uninvestigated symptoms of dyspepsia. The specimens were analyzed for the presence of H pylori using urease analysis, histopathology, and cell culture. The grade and activity of gastritis was assessed using the updated Sydney system.RESULTS: The percentages of Indonesian and Japanese patients who were H pylori-positive at the antrum or body of the stomach were similar (68% and 59.5%, respectively; P = 0.316). Of those who were H pylori-positive, more Japanese patients than Indonesian patients had high levels of polymorphonuclear cells ( P = 0.001), mononuclear cells ( P = 0.013), glandular atrophy ( P = 0.000), and intestinal metaplasia ( P = 0.011) in both the antrum and body of the stomach.CONCLUSION: The grade of gastritis and prevalence of mucosal atrophy and intestinal metaplasia were higher in Japanese patients. The difference between Indonesian and Japanese patients was significant. 相似文献

Atrial fibrillation (AF) is the most commonly encountered clinical arrhythmia and is associated with adverse outcomes and increased healthcare costs. Racial variations in AF are recognized yet poorly understood. In this review we summarize racial differences in AF epidemiology, risk factors, genetics, and outcomes. We identify novel risk factors, inflammatory mediators and biomarkers associated with AF, which have had limited study in racial and ethnic minorities. We describe the mismatch between risk factor burden and AF. We highlight the limited participation of minorities in trials for AF management and stroke prevention that contrasts with observed racial variability in anticoagulation efficacy and practice. Throughout we provide specific strategies for future directions to address gaps in the epidemiology of racial differences and to meet identified racial disparities. We specifically identify areas for further research. We conclude that addressing disparities in prevention and healthcare resource allocation will likely improve AF-related outcomes in minorities. 相似文献

Xanthogranulomatous pyelonephritis (XGP) is a rare variant of chronic pyelonephritis, occurring in the setting of obstructive uropathy and recurrent urinary tract infections (UTIs). It is difficult to diagnose as it can be asymptomatic until late-stage disease. Localized symptoms such as flank pain and dysuria may be attributed to nephrolithiasis or UTIs without prompting need for further workup. Extrarenal manifestations, most notably fistula formation, may present distal to the kidney and not be readily attributed to a renal pathology. The only known definitive therapy is nephrectomy. A delay in diagnosis can lead to fulminant complications or a more technically difficult nephrectomy. We present three cases of XGP, which serve to highlight the possibility of earlier diagnosis and resultant management options, including the potential for nephron-saving strategies. Early clinical and radiologic suspicion through awareness of risk factors may play an important role in preventing disease progression, avoiding late-stage complications, and improving treatment outcomes. 相似文献

Diarrhea and acaroid mites: A clinical study 总被引:7,自引:0,他引:7
AIM: To explore the characteristics of diarrhea caused by acaroid mites.METHODS: Acaroid mites in fresh stools of 241 patients with diarrhea were separated by flotation in saturated saline.Meanwhile, skin prick test, total IgE and mite-specific IgE were detected in all patients.RESULTS: The total positive rate of mites in stool samples of the patients was 17.01% (41/241), the positive rates of mites in male and female patients were 15.86 % (23/145)and 18.75 % (18/96), respectively, without significant difference (P>0.05). The percentage of skin prick test as ″+++″″++ ″″+ ″″±″″-″ was″+++, ″++″,″ +″, ″±″ and ″-″was 9.13 % (22/241), 7.47 %(18/241), 5.81% (14/241), 4.98 % (12/241) and 72.61%(175/241), respectively. The serum levels of total IgE, mitespecific IgE in patients with and without mites in stool samples were (165.72±78.55) IU/ml, (132.44±26.80) IU/ml and (145.22±82.47) IU/ml, (67.35±45.28) IU/ml,respectively, with significant difference (P<0.01). The positive rate of mites in stool samples in staffs working in traditional Chinese medicine storehouses or rice storehouses (experimental group) was 26.74 % (23/86), which was significantly higher than that (11.61%, 18/155) in people engaged in other professions (X2=8.97, P<0.01).CONCLUSION: Acaroid mites cause diarrhea and increase serum levels of total IgE and mite-specific IgE of patients,and the prevalence of diarrhea caused by acaroid mites is associated with occupations rather than the gender of patients. 相似文献

Acute pancreatitis and amiodarone: A case report 总被引:4,自引:0,他引:4
Amiodarone, a class Ⅲ antiarrhythmic drug, is one of the most effective drugs used in the treatment of ventricular and paroxysmal supraventricular tachyarrhythmia. Adverse effects of amiodarone including pulmonary toxicity, hepatotoxicity, aggravation of arrhythmia, and thyroid diseases are well understood. A 66-year old woman with acute pancreatitis was admitted to our hospital with the complaint of epigastralgia radiating to both flanks for two months. Her symptoms and elevation of pancreatic enzymes did not respond to conventional medical treatment of pancreatitis for 18 d. No known causal factors for pancreatitis such as biliary tract stone, hypertriglyceridemia and alcohol consumption could be identified. Under the suspicion of amiodarone-induced acute pancreatitis, amiodarone was substituted by propafenone. Her symptoms soon alleviated and serum lipase level declined. Three months after hospital discharge, the abdominal pain did not recur. Amiodarone was approved to treat recurrent ventricular fibrillation or sustained ventricular tachyarrhythmia that has been resistant to other medications since 1986. Pancreatitis is a very rare adverse effect associated with the use of amiodarone, and only four cases of amiodarone-induced pancreatitis have been reported in literature. We report a patient who developed acute pancreatitis during amiodarone therapy. 相似文献

Background and aimThe gut microbiota (GM) plays an essential role in maintaining health, and imbalance in its composition is associated with the physiopathogenesis of metabolic diseases, such as obesity and type 2 diabetes mellitus (T2DM). Diet and antibiotics are known modulators of GM, but the influence of physical exercise in modulating the diversity and abundance of hindgut bacteria is still poorly understood. The aim of this systematic review was to investigate the scientific evidence about the effect of physical exercise on GM modulation in subjects with obesity and T2DM.Methods and resultsA search in PubMed, Web of Science, Scopus, Cochrane and Embase databases using keywords related to gut microbiota, physical exercise and metabolic diseases was performed. Eight clinical studies met the inclusion criteria, six in subjects with obesity and two in individuals with T2DM. In three studies carried out in individuals with obesity, exercise was able to positively modulate the diversity of GM and the abundance of some species of bacteria, mostly by increasing the Bifidobacteriaceae family, and the Bacteroides and Akkermansia genera, and by decreasing the Proteobacteria phylum. The studies in subjects with T2DM found that physical exercise may reduce metabolic endotoxemia markers.ConclusionsPhysical exercise may be a beneficial modulation strategy of GM composition in metabolic diseases, specifically aerobic exercises carried out for at least 6 weeks with moderate or high intensity. Nevertheless, well-designed clinical trials are needed to clarify the role of physical exercise on GM in subjects with obesity and T2DM. 相似文献

Introduction
Epistaxis is the most common otorhinolaryngological emergency. Whether there is an association or cause and effect relationship between epistaxis and hypertension is a subject of longstanding controversy.Objective
The aim of our study is to evaluate the relationship between epistaxis and hypertension.Materials and methods
This study was conducted at Olaya Medical Center (Riyadh) during the period between May 2013 and June 2014. A total of 80 patients were divided into two groups: Group A consisted of 40 patients who presented with epistaxis, and Group B consisted of 40 patients who served as a control group. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) was performed for all patients. Patients were followed up for a period of three months.Results
Readings of blood pressure (BP) were similar between the two groups regarding BP at presentation, ABPM, and BP at three months. There was a higher number of attacks in patients with history of hypertension. There was highly significant positive correlation between number of attacks of epistaxis and BP readings. Systolic BP at presentation was higher in patients who needed more complex interventions such as pack, balloon or cautery than those managed by first aid.Conclusion
We found no definite association between epistaxis and hypertension. Epistaxis was not initiated by high BP but was more difficult to control in hypertensive patients. 相似文献17.

Accumulation of β-amyloid (Aβ) plaques is a pathological hallmark of Alzheimer disease. Aβ levels in animals and adults were reported to be associated with postoperative cognitive dysfunction (POCD). Our goal was to determine the plasma levels of Aβ in infants and young children after cardiac surgery with cardiopulmonary bypass (CPB).Forty-two infants and young children aged from 1 to 35 months undergoing cardiac surgery with general anesthetics were prospectively enrolled from January to June 2014 at a tertiary medical center. Perioperative plasma samples were obtained, and Aβ42 and Aβ40 levels were measured using ELISA. Other clinical characteristics of the patients were also recorded.Plasma levels of Aβ42 and Aβ40 decreased dramatically 2 hours after surgery and remained significantly lower 6 hours after operation. Baseline Aβ42 level correlated significantly with surgical intensive care unit (SICU) length of stay (LOS) and was an independent predictor for SICU LOS on multivariate analysis.Cardiac surgery with CPB decreases plasma Aβ levels. Plasma levels of Aβ42 and Aβ40 might be used as novel biomarkers for predicting outcomes in the patient population. 相似文献

Background:Type A aortic intramural hematoma(IMH) is characterized by aortic lesions involving the ascending aorta and aortic arch, with no detectable intimal tear on imaging, no true or false lumen, and no direct communication between the hematoma and the vascular lumen. The typical pathological changes present as annular or crescent-shaped thickening of the ascending aortic wall. Due to the substantially higher risk associated with Type A IMH compared to Type B IMH, treatment approaches vary a... 相似文献
