Infection with "pathogenic" microorganisms but without clinically apparent disease has been variously defined as latent, subclinical, dormant , occult, and inapparent. These terms are employed with varying meanings by clinicians, veterinarians, phytopathologists, and other biologists. For the sake of greater consistency, however, three general categories of infections without apparent disease h...

Background: Occult bacterial infection is a proposed etiology of low back pain (LBP). However, causative link between LBP and bacteria remains unconfirmed. Herein, we determined the incidence occult discitis in patients receiving surgery for LDH. Methods: Study Design: prospective cohort study. Inclusion criteria: consecutive adult undergoing discectomy symptomatic Exclusion prior epidural ster...

Occult hepatitis B virus (HBV) infections have been identified in patients with chronic hepatitis C virus (HCV) infection, although the clinical relevance of occult HBV infection remains controversial. We searched for serum HBV DNA in 106 HBsAg negative/anti-HBc positive patients with chronic HCV infection and in 150 blood donors HBsAg negative/anti-HBc positive/anti-HCV negative (control group...

nowadays, the presence of hbv dna in the absence of hbsag; occult hepatitis b infection; (obi), is a known clinical entity along with the rapid influx of research being conducted on  its clinical relevance. biologists and clinicians alike have a recent-standing interest in this regards. obi has been described in several clinical settings. however, the data on its prevalence among immunized and ...

conclusions with our laboratory diagnostic method, it seems that there are no cases of oci in patients with aih. however, we recommend further studies with more samples and more precise laboratory method. results six males and 29 females with mean disease duration of 77.1 ± 39.5 month and mean age of 43.62 ± 12.67 years were investigated. all cases were negative for anti-hcv antibody and we cou...

The hepatitis B virus (HBV) is one of the most frequently transmitted agents in dialysis units. Occult hepatitis B is characterized by HBV infection without detectable surface antigen (HBsAg) in the patient's serum, a positive or negative HBV DNA marker result in the serum and a positive result in the liver tissue, which leads to the potential risk of transmission during renal replacement thera...

BACKGROUND The purpose of this study was to investigate the incidence of cervical metastasis in squamous cell carcinoma (SCC) of hard palate and maxillary alveolus and to define its impact factors. METHODS We conducted a retrospective study of patients surgically treated for SCC of hard palate and maxillary alveolus from 2002 to 2011. In situ hybridization was performed to detect high-risk hu...

Klebsiella pneumoniae is the leading cause of liver abscess in diabetic patients in Taiwan. We report the case of a diabetic patient with a history of four episodes of K. pneumoniae liver abscess within 3 years. The patient later developed Streptococcus bovis bacteremia originating from a colon tumor with complications of endocarditis, osteomyelitis, and silent splenic abscess. Occult colon tum...

Although overt hepatitis B virus (HBV) infection promotes the onset of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-infected patients, the effect of occult HBV infection remains unclear. The aim of this study was to investigate the effect of occult HBV infection on the early-onset of HCC in HCV-infected patients. A total of 173 HCC patients with HCV infection were enrolled and clas...
