Isochromosome 7 [i(7q)] is a cytogenetic abnormality characterised by an abnormal chromosome, in which the short arm is absent and the long arm is duplicated. Changes in chromosome 7, particularly deletion of 7 and 7q, are associated with poor prognosis, but i(7q) is rarely observed in MDS and its prognostic role is unknown. Case presentation: This case report was based on a retrospective review of medical records of a patient at Walter Cantidio University Hospital. Ethics Committee approval was obtained (number 3.066.267). A 23-year-old male patient was diagnosed with MDS with multiline dysplasia, with cytogenetic alteration i(7)(q10) as the only abnormality in 8 of 20 metaphases. The patient was classified as low risk by the Revised International Prognostic Scoring System. After 7 years of clinical follow-up, the patient remains asymptomatic but with persistent neutropaenia and thrombocytopaenia, and a reduction in the number of metaphases being the only change. Conclusion: The present case suggests that this chromosomal modification is indicative of a good prognosis in MDS; however, as it is a rare change in the disease, and patients should be closely monitored.

Our characterization of over 35 million read, write, and management requests spanning a 28-day period is done at three different levels. The user view characterizes how individual users interact with blogosphere objects (blogs); the object view characterizes how individual blogs are accessed; the server view characterizes the aggregate access patterns of all users to all blogs. The more-interactive nature of the blogosphere leads to interesting traffic and communication patterns, which are different from those observed for traditional web content. We identify and characterize novel features of the blogosphere workload, and we show the similarities and differences between typical web server workloads and blogosphere server workloads. Finally, based on our main characterization results, we build a new synthetic blogosphere workload generator called GBLOT, which aims at mimicking closely a stream of requests originating from a population of blog users. Given the increasing share of blogspace traffic, realistic workload models and tools are important for capacity planning and traffic engineering purposes.
