The patient, a 6-month-old girl, initially presented with choking and feeding difficulty. Brain MRI revealed a large tumour in the right posterior fossa, originating from the inferior aspect of the right cerebellar hemisphere. She underwent surgery to remove the tumour a few days before the CSF was sampled. Histologic examination confirmed the diagnosis of Atypical Teratoid Rhabdoid Tumor. The macrophage is seen stretching its pseudopods –like a well-trained athlete reaching out to make a catch– to grab a red blood cell (RBC) (short arrow). Particles of digested debris from other RBCs are noted within its cytoplasm (long arrow) – evidence that this phagocytic act had been performed several times before. Macrophages, via chemotaxis, play a significant role in cleansing surgical sites by removing debris and organisms.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85009355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was designed to examine if rituximab increases the risk to develop non-neutropenic infection (NNI). Medical records of 202 patients diagnosed as follicular lymphoma or small lymphocytic lymphoma were reviewed. Negative binomial regression was used to estimate relative risk (RR) of NNI. Rituximab (n= 41) and non-rituximab (n= 161) groups had a total of 31.636 and 195.691 reviewed patient days, and recorded a total of 67 and 154 infections, respectively. Negative binomial regression analysis revealed significant effects for the treatment (rituximab vs. non-rituximab) and age (p< 0.01). The RRs of viral and bacterial NNI for rituximab group compared to nonrituximab group were 3.33 and 2.60, respectively; while the RRs for one year increment of age were 1.03 and 1.04, respectively. The time-to-first viral and bacterial NNI for rituximab group were significantly faster than non-rituximab group. Rituximab may increase the risk of NNI in patients with follicular lymphoma or small lymphocytic lymphoma.","PeriodicalId":49402,"journal":{"name":"Uhod-Uluslararasi Hematoloji-Onkoloji Dergisi","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83738446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
