Meningitis in excessive alcohol consumers acquired in the community.

Etiology, risk factors, treatment and outcome of 21 cases of bacterial meningitis diagnosed in excessive alcohol consumers within 5 years of national community acquired meningitis survey in Slovakia is reported.

The influence of wine Zweigeltrebe and Breslava Chateau Karvaj on blood pressure in healthy volunteers.

Efficacy of varies wine sorts on blood pressure in 21 healthy individuals was prospectively studied. White wine Breslava most significantly decreased systolic blood pressure in comparison to wines from supermarket Veltlin or Frankovka (Blaufränkisch, Caberner Franc) (Raca). Decrease in diastolic blood pressure is similar in both white wines Breslava respectively Veltlin. In the second experiment during 8 hours blood pressure measurement, white wine Breslava from Nove Zamky region more significantly decreased systolic blood pressure in comparison to Low Carpathian wines (region Raca). Both white wines significantly decreased diastolic blood pressure. Red wines from both regions did not have significant influence on systolic or diastolic blood pressure in doses of 1, 2 or 3 dcl.

The studies on the effect of moderate alcohol consumption on mental capacity in elderly and inflammatory markers in coronary heart disease are reviewed.

Predictors of inferior outcome in community acquired bacterial meningitis.

The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (p<0.05), alcohol abuse (p<0.05), diabetes, S. aureus (p<0.05) and gram-negative etiology (A. baumannii, Ps. aeruginosa or Enterobacteriaceae) (36% vs. 11,9%, p<0.05) were predicting inferior outcome. Analysing risk factors for treatment failure (death or failed but cured after change of antibiotic treatment) prior sepsis (34.1% vs. 13.9%, p<0.01) and gram-negative etiology (25% vs. 11.9%, p<0.02) were statistically significant predictors of treatment failure. Neisseria meningitis had less failures (p<0.05). Concerning infection associated mortality again diabetes mellitus (p<0.05), alcoholism (p<0.05) staphylococcal and gram-negative etiology (p<0.05) were significant predictors of death. N. meningitis had surprisingly less treatment failures (appropriate and rapid initial therapy). Neurologic sequellae were more common in patients with alcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

Antimicrobial susceptibility of cerebrospinal isolates from patients with meningitis.

Str. pneumoniae isolates were susceptible to penicillin, all to also ofloxacin and chloramphenicol and cefotaxim and 39 (100%) to cotrimoxazol. Concerning S. aureus, all isolates 22 were susceptible to oxacillin and chloramphenicol, and 21 also to cotrimoxazol. All N. meningitidis isolates but one-10 of all were susceptible to penicillin, all to cefotaxim, chloramphenicol and cotrimoxazol. All H.influenzae isolates were susceptible to ampicillin and chloramphenicol, as well as to ofloxacin and cotrimoxazol. Those surprisingly high susceptibilities to rather "old" antibiotics may be explained by low antibiotic consumption, accessibility and therefore low usage which is a key promoter of resistance both in community and hospital.

Comparison of postsurgical and community acquired bacterial meningitis--analysis of 372 cases within a nationwide survey.

The aim of this study was to assess if differences in etiology and risk factors among 372 cases of bacterial meningitis acquired after surgery (PM) or in community (CBM) have impact on outcome of infected patients. Among 372 cases of bacterial meningitis within last 17 years from 10 major Slovak hospitals, 171 were PM and 201 CBM. Etiology, risk factors such as underlying disease, cancer, diabetes alcoholism, surgery, VLBW, ENT infections, trauma, sepsis were recorded and mortality, survival with sequellae, therapy failure were compared in both groups. Significant differences in etiology and risk factors between both groups were reported. Those after neurosurgery had more frequently Coagulase negative staphylococci (p<0.001), Enterobacteriaceae (p=0.01) and Acinetobacter baumannii (p=0.0008) isolated from CSF and vice versa Streptococcus pneumoniae (p<0.001), Neisseria meningitis (p<0.001) and Haemophillus influenza (p=0.0009) were more commonly isolated from CSF in CBM. Neurosurgery (p<0.001), sepsis (p=0.006), VLBW neonates (p=0.00002) and cancer (p=0.0007) were more common in PM and alcohol abuse (p<0.001) as well as otitis/sinusitis (p<0.001) and Roma ethnic group (p=0.001) in CAM. Initial treatment success was significantly more frequently observed among CAM (p<0.001) but cure after modification was more common in PM (p=0.002). Therefore outcome in both groups was similar (14.6% vs. 12.4%, p=NS).

Bacterial meningitis after sinusitis and otitis media: ear, nose, throat infections are still the commonest risk factors for the community acquired meningitis.

We investigated how many cases of bacterial meningitis in our national survey were associated with sinusitis or otitis media. Among 372 cases of bacterial meningitis within our nationwide 17 years survey, 201 cases were community acquired (CBM) and in 40 (20%) otitis media or sinusitis acuta/chronica were reported 1-5 weeks before onset of CBM. Diabetes mellitus (20% vs. 7.5%, p=0.01), alcohol abuse (35% vs. 15.4%, p=0.003) and trauma (30% vs. 14.9%, p=0.02) were significantly associated with CBM after ENT infections. Concerning etiology, CBM after sinusitis/otitis was insignificantly associated with pneumococcal etiology (50% vs. 33.8 %, NS) and significantly associated with other (L. monocytogenes, Str. agalactiae) bacterial agents (9.9 % vs. 25 %, p=0.008) . However those significant differences for new ENT related CBM had no impact on mortality (12.4 % vs. 5%, NS), failure after initial antibiotics (10 % vs. 9.5%, NS) and neurologic sequellae (12.5 % vs. 15.4 %, NS).

Pseudomonas aeruginosa causing nosocomial meningitis in neonates and children: overview of 15 cases within 10 years.

Risk factors, therapy and outcome of 15 cases of nosocomial meningitis due to Pseudomonas aeruginosa is reviewed. No difference in risk factors was found, however mortality for Ps. aeruginosa was significantly higher (33.3 vs 15.1% p<0.04).

Nosocomial meningitis caused by Staphylococcus other than S. aureus in children: multicentre study.

Analysing 101 cases of nosocomial meningitis due to staphylococci other than S. aureus within last 15 years, coagulase negative staphylococci represented the commonest pathogen. Major risk factor for staphylococcal meningitis was prior neurosurgery, mainly ventriculoperitoneal shunt insertion. Ten of 101 cases were caused by glycopeptide intermediate resistant strains in patients pretreated with multiple combination of antibiotics including vancomycin and shunt exchanges: 76% of strains were also oxacillin resistant.

Neuroinfections complicating foreign body implants after perinatal trauma or meningitis in 60 children.

Meningitis after artificial implants in 60 children, mainly after foreign body infections (FBI) was caused more frequently by coagulase negative staphylococci and Ps. aeruginosa than other organisms and was significantly associated with perinatal trauma, hydrocephalus, haemorrhage or VLBW and had more neurologic sequels despite mortality was similar to other nosocomial meningitis.

Neuroinfections and antimicrobials: do we need new molecules or new strategies?

Within last 15 years, analyzing patterns of etiology and resistance in organisms causing neuroinfections, emergence of resistance has been observed in Slovakia in S. haemolyticus to teicoplanin (11%), Ps. aeruginosa and A. baumannii to meropenem (20%) and Candida spp. (non-albicans Candida spp.) to fluconazol (20%). There are no new antibiotics against carbapenem resistant Ps. aeruginosa and Acinetobacter baumannii.

Infectious diseases in disaster areas/catastrophes.

There is very little data and no prospective research possible in the field of catastrophic medicine (disaster medicine) including infectious diseases. This minireview tries to contribute to the pathogenesis and outcome of infectious diseases in areas after anthropogenic (war, genocide, terrorist attack, industrial disasters) and non anthropogenic (natural) catastrophes (earthquake, floods, tsunamis, hurricanes, volcano eruptions). Therefore ISC received a proposal to create a working group on infectious diseases in areas after catastrophes, better to understand epidemiology, prevention and therapy of infectious diseases occurring in conjunction to various anthropogenic and non anthropogenic (natural) disasters.

Infectious embolisation to the central nervous system from endocarditis: analyses of 99 cases.

Within a cohort of 606 cases of infective endocarditis, 263 were complicated and 99 embolizing, of them 32 to the central nervous system (CNS). Significant predictors of CNS embolisation were inappropriate therapy (p<0.01) and enterococcal etiology (p<0.01). Mortality in patients with CNS emboli was 65% what was significantly higher than in cases without embolisation - 15% (p<0.01).

Trends in risk factors and etiology of 606 cases of infective endocarditis over 23 years (1984-2006) in slovakia.

The aim of this study was to assess trends in risk factors, etiology, outcome and treatment strategies for endocarditis over 23 years in Slovakia. A prospective survey of 606 cases of infective endocarditis (IE) was conducted from 1984-2006. Rheumatic fever as well as previous dental surgery showed decreasing trends within the last 23 years. Also embolic complications of IE declined along with increasing rates of surgically treated patients. No significant changes in etiology were detected apart from the fact that culture-negative endocarditis increased from 10.7% to 55.4% between 1998-2001. Surgically treated patients increased from 22.7% (1984-1990) to 50.1% (2002-2006) and mortality dramatically decreased from 26.7% (1984-1990) to 5.3% (2002-2006). Staphylococcus aureus and coagulase-negative staphylococci were the leading causes (22.4% - 48%) followed by viridans streptococci (12.2%-18.2%) were a relatively stable trend over 23 years of IE in Slovakia.
