[Infection-surveillance experience at a neurological intensive care unit]

[Infection-surveillance is an important part of the infection control system serving the protection of patients and healthcare workers as well. The continuous surveillance of health care associated infections is among the most important fields of patient safety and quality management. The aim of this study was to evaluate the frequency of the health care associated infections among patients at the neurointensive care unit. Moreover, we aimed to identify specific infectionforms and the most frequently occurring pathogens. We performed the study for a half-year according to the HELICSmethod proposed by the National Center of Epidemiology. In this setup we evaluated the infections and risk factors for infection (instrument-use, antibiotic therapy etc.) among the patients who spent at least 48 hours in the neurointensive care unit. During the six-month period, we observed 16 health care associated mono- and polymicrobial infections out of the 88 cases. Mainly Gram-positive pathogens were identified, but we found multidrug-resistant pathogens as well. Clinically diagnosed pneumonia was the most frequent among the infections. These infections were detected by a relatively low microbiological testing rate, which warns to increase sampling frequency to ensure more accurate data on infections. Infection control based on a comparative standardized infection dataset seems to be one of the most important preventive measures.]

[Herpes simplex virus encephalitis (HSVE) is a rare and lifethreatening infection. The clinical signs are diverse and often misleading regarding the aetiology. However, focal seizure with fewer and typical CT/MRI finding should always raise the possibility of HSVE as early diagnosis and antiviral therapy is crucial. Before the advent of molecular techniques and high-tech imaging histological examination from multiple brain biopsies were often necessary. Although nowadays PCR and other molecular methods may provide an aetiological diagnosis some cases need neuropathological verification. Due to the high IgG seropositivity rate in the population the plasma IgG titer is not diagnostic and elevation of its plasma level requires several weeks. We report the case of a 25-years old male patient who initially presented with epileptic fits. There was no final diagnosis and causal treatment in the district general hospital. The patient was admitted to our institution in comatose state on day 9; the initiated diagnostic tests and therapy could not save the patient who died next day. The autopsy and subsequent neuropathological examination revealed HSVE. We present a flowchart on diagnostic work-up and special techniques to aid diagnosis in suspected viral encephalitis.]

[Occurence and molecular pathology of low grade gliomas]

MURNYÁK Balázs, CSONKA Tamás, KLEKNER Álmos, HORTOBÁGYI Tibor

[Background - The WHO grade I. and II. low-grade gliomas represent nearly the 15% of all primary brain tumors. These tumours contain clinically, hisologically and molecularly distinct tumor types. According to their histologic characteristic, grade II glial tumours are the diffuse astrocytoma, oligodendroglioma and oligoastrocytoma subgroups; the ependymal tumors are not included in this study. Methods - In our publication, we analysed the histological diagnosed glioma cases between 2007 and 2011 at our institution. Results - Low-grade gliomas were diagnosed in 127 cases (62 male / 65 female), and the mean ages were 39 years (±20.3). More than half of the cancers were localizated in the frontal lobe, and the second most frequent area was the temporal lobe. Finally, we comlete our report with an overview of major molecular pathways in low-grade gliomas.]
