Brucella endocarditis is an uncommon but not rare manifestation of brucellosis in our country. We report six adult patients aged 20 to 45 years. Two of our patients were female, and this is the first time that Brucella endocarditis was reported in adult females. In five cases, aortic valve replacement was performed in addition to combined antibiotic therapy. One of them died due to immedia...

While analyzing CAIDA Internet traces of TCP traffic to detect instances of data reneging, we frequently observed four misbehaviors in the generation of SACKs. These misbehaviors could result in the data sender mistakenly thinking data reneging occurred. Further testing detected two additional SACK generation misbehaviors which in the worst case could result in a data sender receiving a SACK fo...

Most known by his literary ability, the words of the neurologist Oliver Sacks (1933-2015) also had an impact on scientific community about the role of levodopa on parkinsonisms. Different from the most authors and based on his experience described on the book "Awakenings", he had a pessimistic opinion about levodopa, which was related on many articles written by himself and colleagues in early ...

secondary systemic vasculitis and nonbacterial endocarditis are rare events. we report a case presented with different manifestations of underlying malignancy such as systemic vasculitis, non bacterial endocarditis and dic (disseminated intravascular coagulopathy). efforts to find the source of malignancy was unsuccessful and due to patient's unwillingness for further evaluation, finally under ...

introduction: infective endocarditis is a rare, fatal ,with high morbidity in children, since infective endocarditis in children was not assessed in our conditions so our study was attempted.   material and methods: this cross-sectional  study  include 19 patients less than 18 years old  with endocarditis   were hospitalized in the department of pediatric cardiology( university of mashhad medic...

Background/Objective: The aim of the present preliminary study was to assess the demographic, clinical, paraclinical, microbiological, echocardiographic, and therapeutic profile as well as in-hospital outcome of patients with infective endocarditis at a referral center for various infectious diseases in Iran.Methods: Required demographic, clinical, plausible complications and paraclinical data ...

We study linear estimators for the weighted integral of a stochastic process. The process may only be observed on a nite sampling design. The error is deened in mean square sense, and the process is assumed to satisfy Sacks-Ylvisaker regularity conditions of order r 2 N 0. We show that sampling at the quantiles of a particular density already yields asymptotically optimal estimators. Hereby we ...

It is shown that for any computably enumerable degree a 6= 0, any degree c 6= 0, and any Turing degree s, if s ≥ 0, and c.e. in a, then there exists a c.e. degree x with the following properties, (1) x < a, c 6≤ x, (2) a is splittable over x, and (3) x = s. This implies that the Sacks’ splitting theorem and the Sacks’ jump theorem can be uniformly combined. A corollary is that there is no atomi...

  Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, i...
