Tubercular liver abscess is a rare entity even in an endemic area for TB. We report here a rare case of pediatric tuberculous liver abscess, the etiology of which was established using recently introduced Cartridge based nucleic acid amplification test (CBNAAT). A 7 years old male child presented with vomiting, pain abdomen and fever. Hepatomegaly was found on examination. Ultrasound of abdomen revealed two liver abscesses in the right lobe. Patient remained symptomatic even after empirical antimicrobial therapy. On diagnostic tap Gram stained smear of the pus showed polymorphs with negative culture. CBNAAT was positive for Mycobacterial tuberculosis and sensitive to rifampicin. Subjecting difficult extrapulmonary specimens to relevant microbiological investigations along with CBNAAT and other newer methods may improve diagnosis of tuberculosis in such rare cases thus leading to an early management and decrease in morbidity. 相似文献

Purpose of Review
The purpose of this review is to discuss the current evidence regarding the impact of sarcopenia on patients with cirrhosis awaiting liver transplantation and to determine if its presence should be considered a criterion for expedited transplantation or a contraindication for transplantation.Recent Findings
Sarcopenia is a negative predictor of survival in patients on a waiting list and after liver transplant. The gut-liver axis and the liver-muscle axis have been explored to understand the complex pathophysiology of sarcopenia.Summary
Sarcopenia is a frequent finding in patients with cirrhosis. The diagnosis is ideally based on cross-sectional image analysis (CT or MRI) and treatment consists of optimization of caloric and protein intake. To date, prioritizing tools for liver transplantation have not included nutrition or sarcopenia parameters. Patients with a low Model for End-Stage Liver Disease (MELD) or MELD-Na score and sarcopenia would benefit from prioritization for transplant in order to reduce time on waiting list and therefore mortality.4.

The sample entropy (SampEn) has been widely used to quantify the complexity of RR-interval time series. It is a fact that higher complexity, and hence, entropy is associated with the RR-interval time series of healthy subjects. But, SampEn suffers from the disadvantage that it assigns higher entropy to the randomized surrogate time series as well as to certain pathological time series, which is a misleading observation. This wrong estimation of the complexity of a time series may be due to the fact that the existing SampEn technique updates the threshold value as a function of long-term standard deviation (SD) of a time series. However, time series of certain pathologies exhibits substantial variability in beat-to-beat fluctuations. So the SD of the first order difference (short term SD) of the time series should be considered while updating threshold value, to account for period-to-period variations inherited in a time series. In the present work, improved sample entropy (I-SampEn), a new methodology has been proposed in which threshold value is updated by considering the period-to-period variations of a time series. The I-SampEn technique results in assigning higher entropy value to age-matched healthy subjects than patients suffering atrial fibrillation (AF) and diabetes mellitus (DM). Our results are in agreement with the theory of reduction in complexity of RR-interval time series in patients suffering from chronic cardiovascular and non-cardiovascular diseases. 相似文献

OBJECTIVES: The objective of this review was to evaluate the efficacy and safety of rifampin, opioid antagonists, or bile acid binding agents in the treatment of cholestasis-related pruritus (CAP) from available randomized controlled trial evidence. METHODS: In addition to a comprehensive gray literature search, the Cochrane Library, MEDLINE, EMBASE, PubMed, and Web of Science were searched. Only full-text RCTs in participants (>75% adult) with CAP on at least one of the three medications were included. The primary outcome was change in pruritus score, recorded as a continuous or dichotomous outcome. Two independent reviewers performed trial selection and quality assessment. RESULTS: From 487 citations, 12 RCTs were included. Rifampin (standardized mean difference [SMD]-1.62, 95% CI -3.05 to -0.18) and opioid antagonists (SMD -0.68, 95% CI -1.19 to -0.17) significantly reduced CAP. The two cholestyramine studies were too heterogeneous to pool. Although cholestyramine (P= 0.35) and rifampin (P= 0.96) were not associated with greater side effects compared with placebo, opioid antagonists were (number needed to harm = 2.6, 95% CI 1.4-25). CONCLUSIONS: The available RCTs are small, few in number, and use varying scales for measuring pruritus. Although both opioid antagonists and rifampin demonstrated a reduction in pruritus, there were insufficient data to judge the efficacy of cholestyramine. Opioid antagonists were associated with transient side effects in a significant proportion of patients. A longer well-designed randomized controlled trial is needed to confirm the efficacy of bile acid binding agents and accurately assess adverse events. 相似文献

Potential role of c-Jun NH2-terminal kinase in allergic airway inflammation and remodelling: effects of SP600125 总被引:5,自引:0,他引:5

Asthma is a chronic inflammatory disease of the airways associated with structural changes such as increased airway smooth muscle mass, which may contribute to impairment of lung function. To determine whether c-Jun NH2-terminal kinase (JNK) of the mitogen-activated protein kinase signalling pathway participated in these changes, the effects of an inhibitor, SP600125 (anthra [1, 9-cd] pyrazole-6 (2H)-one), were examined in a murine model of chronic airway inflammation and remodelling. Mice sensitised to ovalbumin were exposed to ovalbumin aerosol and were treated with SP600125 [30 mg kg(-1) intraperitoneal (i.p.)] on days of exposure. SP600125 significantly reduced eosinophil and lymphocyte numbers in bronchoalveolar lavage fluid, suppressed eosinophilic inflammation within the bronchial submucosa, inhibited goblet cell hyperplasia, and increased airway smooth muscle cell number in allergen-exposed mice. SP600125 also inhibited allergen-induced increase in bronchial responsiveness. SP600125 inhibited JNK activity in the challenged lungs. Although SP 600125 may also have other effects, we conclude that c-Jun NH2-terminal kinase may play a role in allergen-induced inflammation and remodelling associated with bronchial hyperresponsiveness. 相似文献

BACKGROUND: Mutations in the RyR2-encoded cardiac ryanodine receptor/calcium release channel and in CASQ2-encoded calsequestrin cause catecholaminergic polymorphic ventricular tachycardia (CPVT1 and CPVT2, respectively). OBJECTIVES: The purpose of this study was to evaluate the extent of genotypic and phenotypic heterogeneity among referrals for CPVT genetic testing. METHODS: Using denaturing high-performance liquid chromatography and DNA sequencing, mutational analysis of 23 RyR2 exons previously implicated in CPVT1, comprehensive analysis of all translated exons in CASQ2 (CPVT2), KCNQ1 (LQT1), KCNH2 (LQT2), SCN5A (LQT3), KCNE1 (LQT5), KCNE2 (LQT6), and KCNJ2 (Andersen-Tawil syndrome [ATS1], also annotated LQT7), and analysis of 10 ANK2 exons implicated in LQT4 were performed on genomic DNA from 11 unrelated patients (8 females) referred to Mayo Clinic's Sudden Death Genomics Laboratory explicitly for CPVT genetic testing. RESULTS: Overall, putative disease causing mutations were identified in 8 patients (72%). Only 4 patients (3 males) hosted CPVT1-associated RyR2 mutations: P164S, V186M, S3938R, and T4196A. Interestingly, 4 females instead possessed either ATS1- or LQT5-associated mutations. Mutations were absent in >400 reference alleles. CONCLUSION: Putative CPVT1-causing mutations in RyR2 were seen in <40% of unrelated patients referred with a diagnosis of CPVT and preferentially in males. Phenotypic mimicry is evident with the identification of ATS1- and LQT5-associated mutations in females displaying a normal QT interval and exercise-induced bidirectional VT, suggesting that observed exercise-induced polymorphic VT in patients may reflect disorders other than CPVT. Clinical consideration for either Andersen-Tawil syndrome or long QT syndrome and appropriate genetic testing may be warranted for individuals with RyR2 mutation-negative CPVT, particularly females. 相似文献
