Haemophillus influenzae community acquired meningitis occurrence in children despite 10 years vaccination

Despite of 10 years vaccination of all children within 1st year in Slovakia against H. influenzae, this severe infection still occurs. Among 201 cases of community acquired bacterial meningitis, 14 (7%) were caused by H. influenzae serotype B. Outcome however, after early institution of treatment was fortunately positive - only 1 patient died (7.1% mortality) and in 2 other neurologic sequellae occurred (14.3%), which were transient and mild.

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).

Wine: positive and negative effects to neurologic, infectious and cardiovascular diseases

Data on both positive (protective) and negative effect of wine on cardiovascular, neurologic and immune system are briefly reviewed.

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).

Gram-negative bacillary community acquired meningitis is not a rare entity in last two decades

The aim of this short note is to assess gram-negative bacillary community acquired meningitis (CBM) and nosocomial meningitis (NM) within 17 years nationwide survey. All cases of gram-negative bacillary CBM within 1990-2007 were assessed in national database of 372 patients with bacterial meningitis: 69 of gram-negative cases were nosocomial and 24 of gram-negative meningitis cases were CBM. Those 24 cases were compared with all CBM (201 cases) for risk factors and outcome. Among nosocomial gram-negative pathogens, A. baumannii in 23 cases, Ps. aeruginosa in 15 cases and Enterobacteriaceae in 31 cases were isolated. Among CBM, in 13 cases Enterobacteriaceae (Escherichia coli 6, Klebsiella pneumoniae 3, Proteus mirabilis 2, Enterobacter cloacae 2), in 5 cases Ps. aeruginosa and in 6 cases Acinetobacter baumannii were isolated from cerebrospinal fluid (CSF). The only significant risk factor for CBM due to gram-negative bacilli was neonatal age (12.5% vs. 3.5%, p=0.04) as underlying disease. However, mortality among gram-negative bacillary meningitis was significantly higher (12.4% vs. 37.5%, p=0.001) in comparison to other meningitis.

Neuroinfections due to Listeria monocytogenes

Listeria monocytogenes is not a rare pathogen causing meningitis, mainly in small children and in close contacts to livestock. The pathogen is naturally resistant to cephalosporins and some glycopeptides as well, therefore despite of syndromologic diagnosis of meningitis and initial therapy with 3rd generation cephalosporins according to the guidelines therapeutic failures with clinical consequences may occur.

Occurrence of coronary heart diseases and hypertension among wine and concentrating alcohol consumers

There was a significant difference in occurrence of coronary hearth disease and arterial hypertension occurrence in the sample of 16,345 patients living in northeast part of Slovak republic near Polish frontier versus to the viticulture regions of Nove Zamky, Sturovo in favour of villages in Bardejov region. Another difference was that 80 years and older respondents live significantly more frequently in south Slovakian viticulture villages.

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.

Point prevalence study of the spectrum of infectious diseases and antimicrobial drug use in homogenous slum population of Mukuru in Nairobi

We performed a prospective point prevalence study with a simple prospective protocol and analyzed spectrum of infections (ID) etiology and antimicrobial therapy in all cases coming for one month (June 2006). Respiratory tract infections represented 33% of all visits followed by diarrheal infections (197 cases) and sexually transmitted disease (86), skin and soft tissue infection (68), AIDS (40) and malaria (26) cases. Majority of isolates were St. aureus (only 3 MRSA), C. albicans and NAC (19), (only 2 Fluconazol resistant) and S. pneumoniae (8) (2 penicillin resistant).

Bacterial meningitis after craniocerebral trauma in the community

Craniocerebral trauma is one of major risk factors for development of meningitis. We reviewed 30 cases of bacterial meningitis occurring in community after craniocerebral trauma. Alcohol abuse was significant risk factor occurring in trauma patients with meningitis present in 50% in our cohort (p=0.0001). The most common pathogen in posttraumatic meningitis was Str. pneumoniae (90% vs. 33.8%, p=0.0001). However mortality was very low, only 5% probably because of early diagnosis and treatment of patients at risk for bacterial meningitis but neurologic sequellea were significantly more common (p=0.00001) in patients after craniocerebral trauma.

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).

Hair whorls of Holstein Friesian heifers and affects on growth and behaviour

Abstract. The aim of this study was to investigate whether the growth, number of crossed squares in the open-field test and time of traversing the maze in the maze are affected by the height position of they facial whorl in heifers which were kept in experimental conditions. Fifty-eight Holstein heifers were used. The hair whorl position was determined as hair whorl high, middle and low. Heifers with a high whorl had significantly higher body weight at days 360 (P<0.05) and 540 (P<0.01) and average daily gains from birth to 21 months (P<0.001) and from the 6th to 21st months (P<0.01) of age. We did not find any significant differences among hair whorl position groups either in open-field tests or in the maze. The present results show that the growth is influenced in the investigated dairy cattle by height of their facial whorl.

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 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).

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).

National 14 years survey of 171 cases nosocomial meningitis in children and comparison of two periods 1993-1998 to 1999-2006

In 1993-1998 and in 1999-2004 we have performed two surveys of pediatric bacterial meningitis in all 8 neurosurgery/pediatrics and infectious diseases departments in Slovakia. We have detected 101 and another 54 cases with attributable mortality of 15% and sequellae in 18%.

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 due to Enterococcus faecalis in children

Enterococcal meningitis is a rare complication of neurosurgical procedure or high technology treatment of children and occurs mainly imunocompromised neonates with very low birth weight, severe prematurity and complicates sometime ventriculoperitoneal shunt insertion or perinatal trauma. E. faecalis caused 10 nosocomial meningitis and all strains were susceptible to vancomycin and chloramphenicol, and in our database 90% also to gentamicin and ampicillin. Mortality in our group of 10 children was 20% what is insignificantly higher than overall mortality in the whole cohort of meningitis within last 15 years in our database (15.1%). Early empiric therapy should include also ampicillin or vancomycin, if enterococcal etiology is suspected.

Postsurgical meningitis caused by Acinetobacter baumannii associated with high mortality

Twenty five (25) cases of nosocomial postsurgical meningitis due to Acinetobacter baumannii meningitis were compared to other 146 cases of meningitis after surgery caused by other pathogens. Prior neurosurgical ventriculo-peritoneal shunt insertion and CNS abnormality as well as very low birth weight were significant risk factors for acquisition of Acinetobacter baumannii meningitis. Mortality - 40% among children with nosocomial meningitis was unacceptably high and significantly higher than among meningitis caused by microorganisms other than Acinetobacter baumannii.

The effect of sire line on growth, ambulating in novel environment and maze learning in heifers

Abstract. The aim of this study was to investigate the influence of sire's lineage on live body growth, movement in open-field arena and time of acrossing the maze of heifers. 54 Holstein heifers, which descended from 7 sires, were used. The highest growth from the birth to 21 months was found in the progeny of sire D, the lowest growth in daughters of sire line B (0.74 ± 0.05 kg vs. 0.62 ± 0.08 kg; P < 0.01). Number of crossed squares in open-field tests did not vary significantly among sire lines. Significant differences were found among sires in the time across of the maze (P < 0.01). Daughters after F and E sires solved the maze more quickly then the others. We found significant relationships between a number of crossed squares during 5 minute open-field test and daily weight gains from the birth to the 6th month of life (r = 0.3712** at the age of 16 weeks and r = 0.3792** at the age of 18 months). Under consideration of the low number of animals analyses showed, that sire's lineage has impact on the growth and maze behaviour.
