The association of cryoglobulinaemia with sustained virological response in patients with chronic hepatitis C

Previous reports suggest cryoglobulinemia might influence the hepatitis C virus (HCV) infection clinical course and treatment response but this association has not been thoroughly evaluated. We aimed to assess the relationship between cryoglobulinemia and sustained viral response (SVR) in patients treated for HCV infection. We included patients with HCV infection treated from January 2003 through December 2006. Biochemical analyses, detection cryoglobulinemia, and liver biopsies were performed prior to treatment. Genotype 1 or 4 infections received Peg-interferon (IFN) alpha-2a or -2b for 48 weeks; genotypes 2 or 3 received IFN alpha for 24 weeks. All patients also received ribavirin. Of 329 enrolled patients, 242 (73%) were male and the median age was 43 years. Cryoglobulinemia was detected in 196 (59.6%) patients; liver biopsy was performed in 301. Multivariate analysis showed an association of cryoglobulinemia with severe active necroinflammation (A3) (adjusted odds ratio [AOR]= 9.48; 95% confidence interval [CI]: 1.50-59.92) and rheumatoid factor (RF) level (AOR= 1.01; 95% CI: 1.00-1.02). Variables associated with advanced fibrosis were age, aspartate aminotransferase and alkaline phosphatase levels, alcohol use, and presence of diabetes. Variables independently associated with SVR were cryoglobulinemia (AOR= 2.33, 95% CI: 1.26-4.32), absence of cirrhosis (AOR= 4.5, 95% CI: 1.4-14.80), and RF level (AOR= 1.008, 95% CI: 1.001-1.014). Our findings suggest cryoglobulinemia is associated with severe necroinflammatory activity in HCV-infected patients. We also provide the first evidence for an association between cryoglobulinemia and higher SVR rates, highlighting its potential role as a prognostic factor for treatment response.184e91e9

Clinical, tomographic aspects and relevance of torus palatinus: case report of two sisters

Despite the nomenclature suggested to be a tumor, torus palatinus (TP) is an overgrowth of the bone in the palatal region and represents an anatomic variation. Its prevalence varies among the population studied and its etiology is still unclear; however, it seems to be a multifactorial disorder with genetics and environmental involvement. Surgical removal of the TP is indicated in the following circumstances: (1) deglutition and speech impairment, (2) cancer phobia, (3) traumatized mucosa over the torus, and (4) prosthetic reasons. The aim of this case report is describe cases that occurred in two sisters, emphasizing the genetic etiology of this anatomic variation. In addition, intra-oral exam and computed tomography scan (axial, coronal and sagittal view) provided a detailed assessment of the TP and elimination of other possible diagnoses, furthermore allowed a better analyzes of the anatomic relation with adjacentes structures. No surgical removal was indicated for both cases.359SI86787

Inflammatory Nodules Following Soft Tissue Filler Use: A Review of Causative Agents, Pathology and Treatment Options

Nodule development is a common complication following the use of fillers for soft tissue augmentation and is commonly categorized as inflammatory or non-inflammatory in nature. Inflammatory nodules may appear anywhere from days to years after treatment, whereas non-inflammatory nodules are typically seen immediately following implantation and are usually secondary to improper placement of the filler. Although inflammatory nodules are more common with permanent fillers such as silicone, inflammatory nodule development following administration of temporary fillers such as hyaluronic acid and collagen has also been reported. Treated many times with corticosteroids due to their anti-inflammatory properties, inflammatory nodules may be secondary to infection or biofilm formation, warranting the use of alternative agents. Appropriate and prompt diagnosis is important in avoiding delay of treatment or long-term complications for the patient. This paper addresses the etiology, development, and studied treatment options available for inflammatory nodules secondary to each of the major classes of fillers. With this knowledge, practitioners may expeditiously recognize and manage this common side effect and thus maximize functional and aesthetic benefit
