OBJECTIVE We have limited understanding on the presentation and survival of primary spinal sarcomas. The survival, recurrence rate, and related prognostic factors were investigated after treatment for primary sarcomas of the spine. METHODS Retrospective analysis of medical records and radiological data was done for 29 patients in whom treatment was performed due to primary sarcoma of the spin...

BACKGROUND Treatment for hepatitis C virus (HCV) can lead to sustained virological response (SVR) in over 90% of people. Subsequent recurrence of HCV, either from late relapse or reinfection, reverses the beneficial effects of SVR. METHODS A search identified studies analysing HCV recurrence post-SVR. The recurrence rate for each study was calculated using events/person years of follow-up (PY...

The progress of 58 patients with first attacks of genital herpes was monitored for up to 30 weeks. The effects of sex (gender), age, social class, and non-psychotic psychiatric illness (as measured by the "general health questionnaire," GHQ) on the recurrence rate of herpes was studied. The recurrence rates, measured by the actuarial percentage recurrence-free curves, showed that the 29 patient...

febrile seizure is the most common form of childhood seizures that occur in 2-5% of them. the purpose of this study was to compare serum sodium level in first simple, multiple and recurrent febrile con-vulsions to answer whether serum sodium levels can predict febrile seizure recurrence in 24 hours and in other febrile episodes? in a retrospective study, sodium serum levels of all children aged...

Patients: 387 women >18 years of age (mean age 34 y, 67% white) who had active, acute candida vaginitis (severity score >3), a positive result on microscopic examination of vaginal secretions, >4 episodes of candida vaginitis in the previous 12 months, and were clinically cured (severity score ,3) at 14 days after receiving 3 sequential doses of fluconazole, 150 mg, at 72 hour intervals. Exclus...

The aim of this retrospective survey was to determine recurrence rates after treatment of basal cell carcinomas in a single academic dermatology department. A total of 1016 patients with 1593 histologically verified basal cell carcinomas (n=1212 primary and n=381 relapsing) were included. Tumour localization, T-stage and the method of treatment were significant predictors of the risk of recurre...

In this project, we use finite-difference to solve the Dirichlet and Poisson problem. Discrete version of the maximum principle is displayed to show the uniqueness and existence of the discrete solution. Then an example is given to interpret different convergence speed under different numerial schemes. Finally, we demonstrate that the discrete solution converges to the desired solution under ap...
