HCV-infected people serve as a reservoir for transmission to others and are at risk for developing chronic liver disease, cirrhosis, and primary hepatocellular carcinoma (HCC). It has been estimated that HCV accounts for 27% of cirrhosis and 25% of HCC worldwide. HCV infection has likely been endemic in many populations for centuries. However, the wave of increased HCV-related morbidity and mortality that we are now facing is the result of an unprecedented increase in the spread of HCV during the 20th century. Two 20th century events appear to be responsible for this increase; the widespread availability of injectable therapies and the illicit use of injectable drugs.展开更多

Although quality standards demand an infection rate 〈 0.67 episodes/patient/year on dialy-sis, the reported overall rate of PD associated infection is 0.24-1.66 episodes/patient/year. It is estimated that for every 0.5-per-year increase in peritonitis rate, the risk of death increases by 4% and 18% of the episodes resulted in removal of the PD catheter and 3.5% re-sulted in death. Improved diagnosis, increased aware-ness of causative agents in addition to other measures will facilitate prompt management of PD associated infection and salvage of PD modality. The aims of this review are to determine the magnitude of the infection problem, identify possible risk factors and provide an update on the diagnosis and management of PD as-sociated infection. Gram-positive cocci such as Staphy-lococcus epidermidis , other coagulase negative staphy-lococcoci, and Staphylococcus aureus （S. aureus ） are the most frequent aetiological agents of PD-associated peritonitis worldwide. Empiric antibiotic therapy must cover both gram-positive and gram-negative organ-isms. However, use of systemic vancomycin and cip-rofoxacin administration for example, is a simple and efficient first-line protocol antibiotic therapy for PD peritonitis - success rate of 77%. However, for fungal PD peritonitis, it is now standard practice to remove PD catheters in addition to antifungal treatment for a minimum of 3 wk and subsequent transfer to hemodi-alysis. To prevent PD associated infections, prophylactic antibiotic administration before catheter placement, adequate patient training, exit-site care, and treatment for S. aureus nasal carriage should be employed. Mupi-rocin treatment can reduce the risk of exit site infection by 46% but it cannot decrease the risk of peritonitis due to all organisms.展开更多

The purpose of this study is to review pathogenesis and prognostic factors of severe acute pancreatitis （SAP）. An extensive medline search was undertaken with focusing on pathogenesis, complications and prognostic evaluation of SAP. Cytokines and other inflammatory markers play a major role in the pathogenesis and course of SAP and can be used as prognostic markers in its early phase. Other markers such as simple prognostic scores have been found to be as e^ective as multifactorial scoring systems （MFSS） at 48 h with the advantage of simplicity, efficacy, low cost, accuracy and early prediction of SAP. Recently, several laboratory markers including hematocrit, blood urea nitrogen （BUN）, creatinine, matrix metalloproteinase-9 （MMP-9） and serum amyloid A （SAA） have been used as early predictors of severity within the first 24 h. The last few years have witnessed a tremendous progress in understanding the pathogenesis and predicting the outcome of SAP. In this review we classified the prognostic markers into predictors of severity, pancreatic necrosis （PN）, infected PN （IPN） and mortality.展开更多

Methods Data were examined from the US National Health and Nutrition Examination Survey （NHANES） II and III, civilian population aged 25 to 90 years. QT weighted means and standard deviations were calculated for all ages. The QTc were evaluated for six QTc： proposed by Bazett （QTcBZT）, Fridericia （QTcFRD）, Hodges （QTcHDG）, Dmitrienko （QTcDMT）, Rautaharju （QTcRTHa） and Framingham （QTcFRM）. Results QTc was strongly related to age and gender, for all formulae except for QTcBZT for women. The relationship between QTc and age was significant regardless of whether the relationship was approximated by a linear or non-linear （quadratic or cubic spline） model. QTc increased more dramatically with age in men. There was a significant （P 〈 0.001） positive relationship between QTc variance and age for each QTc formula for both men and women. There were a greater proportion of individuals with longer QTc with older ages especially age 80 years and above. Conclusion QTc and its variance increase with age. Prolonged QTc is more prevalent in older individuals, especially men.展开更多

However, whether the depletion of Treg benefits to the disease status of HIV infection remains undefined. To address this issue, we enumerated the Treg absolute counts and frequency in 75 antiviral-naive HIV-1-infected individuals in this study. It was found that HIV-infected patients displayed a significant decline in Treg absolute counts but a significant increase in Treg frequency. In addition, with disease progression indicated by CD4 T-cell absolute counts, circulating Treg frequency gradually increased; while Treg absolute counts were gradually decreased, suggesting that the alteration of Treg number closely correlated with disease progression in HIV infection Functional analysis further showed that Treg efficiently inhibit both CD4 and CD8 T cell proliferation in vitro. Thus, our findings indicates that Treg actively participate in pathogenesis of chronic HIV infection, influencing the disease progression.展开更多

METHODS:We performed an analysis of the clinical records of 986 patients(mean age:49±9 years,714 males/272 females) with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection who had undergone HAV antibody testing between January 2008 and December 2009.RESULTS:The overall prevalence of IgG anti-HAV was 86.61%(854/986) in patients with chronic liver disease and was 88.13%(869/986) in age-and gendermatched patients from the Center for Health Promotion.The anti-HAV prevalence was 80.04%(405/506) in patients with chronic hepatitis B,86.96%(20/23) in patients with chronic hepatitis C,93.78%(422/450) in patients with HBV related liver cirrhosis,and 100%(7/7) in patients with HCV related liver cirrhosis.The anti-HAV prevalence according to the decade of age was as follows:20s(6.67%) ,30s(50.86%) ,40s(92.29%) ,50s(97.77%) ,and 60s(100%) .The antiHAV prevalence was significantly higher in patients older than 40 years compared with that in patients younger than 40 years of age.Multivariable analysis showed that age≥40 years,female gender and metropolitan cities as the place of residence were independent risk factors for IgG anti-HAV seropositivity. CONCLUSION:Most Korean patients with chronic liver disease and who are above 40 years of age have already been exposed to hepatitis A virus.展开更多

The laboratory animals such as puppies,albino rats and Swiss mice were infected orally with metacercariae isolated from the fresh water crabs,Potamiscus manipurensis. The fecal specimens of the experimentally infected animals were examined microscopically for Paragonimus eggs at regular intervals. The animals were autopsied on days 35～328 after infection and the isolated worms were flattened between glass slides and fixed in 70% alcohol. The worms were stained with carmine and mounted with Canada balsam for morphological studies. The eggs were collected in 5% formol saline solution for microscopy. The flukes were classified into 4 developmental stages.Results. A total of 11 worms,5 mature,5 immature and 1 pre-adult were recovered. The morphological features of the metacercariae,worms and eggs were similar to those of Paragonimus heterotremus.Conclusion. Manipur is one of the rare areas in the world where Paragonimus heterotremus is prevalent and the puppies are ideal experimental animal host. This species may be one of the important causes of paragonimiasis in animals and humans in Manipur.展开更多

The research was conducted during the period August, 2006 - May, 2007. Of the 63,649 cattles examined at the various abattoirs which are lpata, Sango, Oloje, Baboko, Oke-oyi, Iporin, Panada, Oke-ose and Marafa, 1,434 representing 25.2% were infected with Fasciola species while 114 representing 6.5% were condemned. Iporin slaughter slab had the highest prevalence of 3.6%, followed by panada with 3.4% and Ipata having the least prevalence of 1.6%. Similarly analysis of data on monthly basis showed that March had the highest prevalence of 2.8%, followed by April with 2.6% and December with the least prevalence of 1.8%. Overall infestation was 22.7% while overall condemnation was 6.5%. There was a significant difference （X^2 = 23.7, P 〈 0.05） in the monthly infestation rate. Also, there was no significant difference （X^2 = 10.7, P 〉 0.05） between the infection rate and condemnation among the various abattoirs. The factors responsible for the prevalence of Fasciola specie and pathology of infection are highlighted.展开更多

This study carried out to isolate S. aureus from different clinical cases, also detection of MRSA prevalence and VRSA emergence, in addition to shedding light on strains that have to be multidrug resistance against various antibiotics, The clinical samples were collected from AI-Jumhuory Teaching Hospital patients in Mosul, isolates identification were achieved by conventional procedures including biochemical and physiological tests, and the specific latex agglutination test. The sensitivity pattern achieved by using disk diffusion technique, for MRSA and VRSA detection oxacillin-disk （1 μg） and vancomycin-disk （30 μg） were used respectively. Results revealed, among 17 S. aureus isolates, 7 （41%） were mostly isolated from patients with wound and burn infections. Isolates had high resistance rate against ampicillin （100%） and cefotaxime （81%）, and lower resistance rate against several antibiotics. MRSA was 88% of total isolates, 93.3% of MRSA were multidrug resistance to 3-9 of antibiotics. Six isolates （40%） of MRSA were VRSA. It is concluded that antibiotics other than vancomycin can be used as anti-MRSA agents after a sensitivity test to prevent the prevalence of VRSA, the major cause of this chemotherapy problems maybe irrational and indiscriminate use of broad-spectrum antibiotics.展开更多
