Factors associated with meningitis vaccine awareness and engagement among Latino men who have sex with men in South Florida. J Behav Med 2024; 47:446-457. [PMID: 38581595 DOI: 10.1007/s10865-024-00486-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 03/14/2024] [Indexed: 04/08/2024]
Abstract
Awareness and uptake of the meningitis vaccine remains low among marginalized groups, such as Latino men who have sex with men (LMSM), potentially due to structural and psychosocial barriers in accessing preventative healthcare. The current study explored awareness and uptake of meningitis vaccines among a group of LMSM (N = 99) living in South Florida. A three-pronged variable selection approach was utilized prior to conducting regression models (linear and logistic). Overall, 48.5% of the participants reported little to no knowledge about meningitis vaccines, and 20.2% reported being vaccinated. Living with HIV (OR = 10.48) and time since outbreak (OR = 1.03) were significant predictors of meningitis vaccine uptake. No significant correlates of meningitis vaccine awareness were identified. More research is needed to identify other important factors associated with meningitis vaccine awareness and uptake among LMSM, a multiple marginalized group.

Feasibility, safety, and impact of the RTS,S/AS01 E malaria vaccine when implemented through national immunisation programmes: evaluation of cluster-randomised introduction of the vaccine in Ghana, Kenya, and Malawi. Lancet 2024; 403:1660-1670. [PMID: 38583454 DOI: 10.1016/s0140-6736(24)00004-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 12/22/2023] [Accepted: 01/02/2024] [Indexed: 04/09/2024]
Abstract
BACKGROUND The RTS,S/AS01E malaria vaccine (RTS,S) was introduced by national immunisation programmes in Ghana, Kenya, and Malawi in 2019 in large-scale pilot schemes. We aimed to address questions about feasibility and impact, and to assess safety signals that had been observed in the phase 3 trial that included an excess of meningitis and cerebral malaria cases in RTS,S recipients, and the possibility of an excess of deaths among girls who received RTS,S than in controls, to inform decisions about wider use. METHODS In this prospective evaluation, 158 geographical clusters (66 districts in Ghana; 46 sub-counties in Kenya; and 46 groups of immunisation clinic catchment areas in Malawi) were randomly assigned to early or delayed introduction of RTS,S, with three doses to be administered between the ages of 5 months and 9 months and a fourth dose at the age of approximately 2 years. Primary outcomes of the evaluation, planned over 4 years, were mortality from all causes except injury (impact), hospital admission with severe malaria (impact), hospital admission with meningitis or cerebral malaria (safety), deaths in girls compared with boys (safety), and vaccination coverage (feasibility). Mortality was monitored in children aged 1-59 months throughout the pilot areas. Surveillance for meningitis and severe malaria was established in eight sentinel hospitals in Ghana, six in Kenya, and four in Malawi. Vaccine uptake was measured in surveys of children aged 12-23 months about 18 months after vaccine introduction. We estimated that sufficient data would have accrued after 24 months to evaluate each of the safety signals and the impact on severe malaria in a pooled analysis of the data from the three countries. We estimated incidence rate ratios (IRRs) by comparing the ratio of the number of events in children age-eligible to have received at least one dose of the vaccine (for safety outcomes), or age-eligible to have received three doses (for impact outcomes), to that in non-eligible age groups in implementation areas with the equivalent ratio in comparison areas. To establish whether there was evidence of a difference between girls and boys in the vaccine's impact on mortality, the female-to-male mortality ratio in age groups eligible to receive the vaccine (relative to the ratio in non-eligible children) was compared between implementation and comparison areas. Preliminary findings contributed to WHO's recommendation in 2021 for widespread use of RTS,S in areas of moderate-to-high malaria transmission. FINDINGS By April 30, 2021, 652 673 children had received at least one dose of RTS,S and 494 745 children had received three doses. Coverage of the first dose was 76% in Ghana, 79% in Kenya, and 73% in Malawi, and coverage of the third dose was 66% in Ghana, 62% in Kenya, and 62% in Malawi. 26 285 children aged 1-59 months were admitted to sentinel hospitals and 13 198 deaths were reported through mortality surveillance. Among children eligible to have received at least one dose of RTS,S, there was no evidence of an excess of meningitis or cerebral malaria cases in implementation areas compared with comparison areas (hospital admission with meningitis: IRR 0·63 [95% CI 0·22-1·79]; hospital admission with cerebral malaria: IRR 1·03 [95% CI 0·61-1·74]). The impact of RTS,S introduction on mortality was similar for girls and boys (relative mortality ratio 1·03 [95% CI 0·88-1·21]). Among children eligible for three vaccine doses, RTS,S introduction was associated with a 32% reduction (95% CI 5-51%) in hospital admission with severe malaria, and a 9% reduction (95% CI 0-18%) in all-cause mortality (excluding injury). INTERPRETATION In the first 2 years of implementation of RTS,S, the three primary doses were effectively deployed through national immunisation programmes. There was no evidence of the safety signals that had been observed in the phase 3 trial, and introduction of the vaccine was associated with substantial reductions in hospital admission with severe malaria. Evaluation continues to assess the impact of four doses of RTS,S. FUNDING Gavi, the Vaccine Alliance; the Global Fund to Fight AIDS, Tuberculosis and Malaria; and Unitaid.

Comparison of prophylactic antibiotics for endonasal transsphenoidal surgery using a national inpatient database in Japan. J Antimicrob Chemother 2023; 78:2909-2914. [PMID: 37856687 DOI: 10.1093/jac/dkad329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 10/04/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND The choice of prophylactic antibiotics for use in endonasal transsphenoidal surgery (ETSS) lacks universal standards. This study aimed to investigate the effectiveness of cefazolin, ampicillin and third-generation cephalosporins for preventing postoperative meningitis and secondary outcomes (in-hospital death and the combination of pneumonia and urinary tract infection) in patients who have undergone ETSS. METHODS The study used data from the Diagnosis Procedure Combination database in Japan. Data from 10 688 patients who underwent ETSS between April 2016 and March 2021 were included. Matching weight analysis based on propensity scores was conducted to compare the outcomes of patients receiving cefazolin, ampicillin or third-generation cephalosporins as prophylactic antibiotics. RESULTS Of the 10 688 patients, 9013, 102 and 1573 received cefazolin, ampicillin and third-generation cephalosporins, respectively. The incidence of postoperative meningitis did not significantly differ between the cefazolin group and the ampicillin group (OR, 1.02; 95% CI, 0.14-7.43) or third-generation cephalosporins group (OR, 0.81; 95% CI, 0.10-6.44). Similarly, in-hospital death and the composite incidence of pneumonia and urinary tract infection did not differ between the cefazolin group and the ampicillin or third-generation cephalosporins group. CONCLUSIONS Cefazolin, ampicillin and third-generation cephalosporins as perioperative prophylactic antibiotics for ETSS do not differ significantly in terms of preventing meningitis.

Abstract
BACKGROUND An effective, affordable, multivalent meningococcal conjugate vaccine is needed to prevent epidemic meningitis in the African meningitis belt. Data on the safety and immunogenicity of NmCV-5, a pentavalent vaccine targeting the A, C, W, Y, and X serogroups, have been limited. METHODS We conducted a phase 3, noninferiority trial involving healthy 2-to-29-year-olds in Mali and Gambia. Participants were randomly assigned in a 2:1 ratio to receive a single intramuscular dose of NmCV-5 or the quadrivalent vaccine MenACWY-D. Immunogenicity was assessed at day 28. The noninferiority of NmCV-5 to MenACWY-D was assessed on the basis of the difference in the percentage of participants with a seroresponse (defined as prespecified changes in titer; margin, lower limit of the 96% confidence interval [CI] above -10 percentage points) or geometric mean titer (GMT) ratios (margin, lower limit of the 98.98% CI >0.5). Serogroup X responses in the NmCV-5 group were compared with the lowest response among the MenACWY-D serogroups. Safety was also assessed. RESULTS A total of 1800 participants received NmCV-5 or MenACWY-D. In the NmCV-5 group, the percentage of participants with a seroresponse ranged from 70.5% (95% CI, 67.8 to 73.2) for serogroup A to 98.5% (95% CI, 97.6 to 99.2) for serogroup W; the percentage with a serogroup X response was 97.2% (95% CI, 96.0 to 98.1). The overall difference between the two vaccines in seroresponse for the four shared serogroups ranged from 1.2 percentage points (96% CI, -0.3 to 3.1) for serogroup W to 20.5 percentage points (96% CI, 15.4 to 25.6) for serogroup A. The overall GMT ratios for the four shared serogroups ranged from 1.7 (98.98% CI, 1.5 to 1.9) for serogroup A to 2.8 (98.98% CI, 2.3 to 3.5) for serogroup C. The serogroup X component of the NmCV-5 vaccine generated seroresponses and GMTs that met the prespecified noninferiority criteria. The incidence of systemic adverse events was similar in the two groups (11.1% in the NmCV-5 group and 9.2% in the MenACWY-D group). CONCLUSIONS For all four serotypes in common with the MenACWY-D vaccine, the NmCV-5 vaccine elicited immune responses that were noninferior to those elicited by the MenACWY-D vaccine. NmCV-5 also elicited immune responses to serogroup X. No safety concerns were evident.

Abstract
BACKGROUND Postoperative cerebrospinal fluid (CSF) leak is one of the most common complications after endoscopic endonasal approach to the skull base. OBJECTIVE To analyze the effect of leukocyte-rich and platelet-rich fibrin (L-PRF) as part of a standardized endonasal skull base repair protocol on postoperative infection and CSF leak rate. METHODS One hundred three patients who underwent an endoscopic endonasal approach and were reconstructed using a standard technique (Group A) were compared with 139 patients using the same protocol with the addition of L-PRF (Group B). Postoperative intracranial infection and CSF leak at 6 months were analyzed. RESULTS In patients with intraoperative CSF leak, postoperative leak occurred in 10.8% in Group A and 2.6% in Group B ( P .024), and in patients with intraoperative high-flow leaks, the incidences were 11.7% and 3.1%, respectively ( P .048). L-PRF reduced postoperative CSF leak by 76% in cases with intraoperative CSF leak (relative risk 0.24, 95% CI 0.06-0.87) and by 73% of patients with high-flow leak (relative risk 0.27, 95% CI 0.07-0.99). In patients undergoing surgery for diagnoses other than adenomas, there were no cases of postoperative leak in Group B, whereas in Group A occurred in 13.4% of those with intraoperative leaks ( P .047) and 15.8% with high-flow intraoperative leaks ( P .033). No significant differences were found in patients with pituitary adenoma. Meningitis occurred in 0.97% in Group A vs 2.16% in Group B ( P .639), without differences between subgroups. CONCLUSION L-PRF reduced the rate of postoperative CSF leaks in patients with intraoperative leaks, without differences on postoperative meningitis.

Ultra-short antibiotic prophylaxis guided by preoperative microbiological nasal swabs in endoscopic endonasal skull base surgery. Acta Neurochir (Wien) 2021; 163:369-382. [PMID: 32901395 DOI: 10.1007/s00701-020-04560-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 08/27/2020] [Indexed: 12/24/2022]
Abstract
PURPOSE Endoscopic endonasal skull base surgery (EESBS) is a clean-contaminated procedure. Guidelines regarding the antibiotic prophylaxis in EESBS have not been developed yet, and today, there are no universally accepted protocols. In this article, we investigated the efficacy of our new ultra-short antibiotic prophylaxis protocol for EESBS guided by the cultural results of preoperative microbiological nasal swabs. METHODS We defined as "nasal swab-related antibiotic protocol" the administration of a first-generation cephalosporin (cefazolin 2 g) in patients whose nasal swabs revealed the presence of normal nasal flora or methicillin-sensitive Staphylococcus aureus (MSSA), and the administration of vancomycin 1 g intravenously in patients whose nasal swabs revealed the presence of methicillin-resistant Staphylococcus aureus (MRSA) or with reported cephalosporin/penicillin allergy. This case-control study included 120 patients who underwent EESBS. The case group included 60 cases who received the "nasal swab-related antibiotic protocol," while the control group included 60 cases who received the "standard hospital antibiotic protocol" used in neurosurgery (cefazolin 2 g plus metronidazole 500 mg at induction, and 2 g of cefazolin repeated after 180 min). RESULTS The preoperative microbiological nasal swabs showed normal nasal flora in 42 patients (70%), MSSA in 17 patients (28.3%), and MRSA in 1 patient (1.6%). During the study period, no cases of meningitis or sinusitis occurred in the case group ("nasal swab-related antibiotic protocol"), while two infections (3.3%, 1 sinusitis and 1 meningitis) were reported in the control group ("standard hospital antibiotic protocol"). Mean length of hospitalization was 6.5 days for the case group and 8.5 days in the control group. "Standard hospital antibiotic protocol" is less expensive (range, 2.88-5.42 euros) compared with our new "nasal swab-related antibiotic protocol" (range, 10.02-32.56 euros), but in line with other antibiotic prophylaxis protocols reported in literature. DISCUSSION The low complication rates of our case series (0%) is comparable to complication rates reported in literature (1.6% for meningitis and 8% for sinusitis). Compared with other perioperative antibiotic regimens reported in literature, the "nasal swab-related antibiotic protocol" is cheap and at least equally effective. We discuss the rationale on which we based the choice of chemoprophylaxis, the timing, and the length of our regimen. CONCLUSIONS Our study confirmed the safety and efficacy of our easily applicable and low-cost antibiotic prophylaxis protocol.

Abstract
BACKGROUND Vaccine-preventable diseases significantly influence the health and academic success of college students. Despite the known negative impact of these diseases, vaccination rates routinely fall short of national goals and recommendations. Although vaccination decisions are complex, a recommendation from a health care provider is one of the key motivators for individuals receiving a vaccine. Motivational interviewing (MI), a counseling approach primarily used to address substance abuse, can be applied to other health-related behaviors. LOCAL PROBLEM Despite previous quality improvement efforts aimed at increasing vaccine rates for influenza, human papillomavirus (HPV), and meningitis B (MenB), vaccinations at large university health centers have been well below benchmarks set by Healthy People 2020. METHODS This study was guided by the Theory of Planned Behavior and included MI training and regular reinforcement for health care providers to address vaccine hesitancy with college students. RESULTS Influenza vaccination rates improved, but HPV vaccine rates remained stable and MenB vaccine rates decreased compared with the previous year. Clinicians demonstrated a significant increase in knowledge of MI techniques after a targeted educational intervention. Repeat measures indicate the potential for sustained improvement when ongoing reinforcement is provided. CONCLUSION MI can be an effective part of a strategy to increase vaccination rates.

Abstract
BACKGROUND Health care-associated meningitis or ventriculitis (HCAMV) is a serious complication in different neurosurgical procedures and is associated with significant morbidity and mortality. We aimed to investigate whether an educational intervention program could reduce the HCAMV incidence in patients undergoing postsurgery external ventricular drainage and wound management. METHODS We enrolled 2,904 patients from the neurosurgery intensive care unit between January 1, 2016 and December 31, 2018. The medical staff undertook an educational program developed by a multidisciplinary team on correct external ventricular drainage insertion and maintenance. The program included a 9-page self-learning module on the HCAMV risk factors and operational improvements. Each participant completed a pre- and posttest on their HCAMV knowledge. RESULTS We found that 38 of 693 (5.48%) patients presented with infection in the preintervention 9-month period. In the 27-month postintervention period, the proportion of HCAMV incidence dropped by 52.19% (P < .0001) to 58 of 2,211 (2.62%) patients. CONCLUSIONS Educational intervention aimed at the neurosurgery intensive care unit staff could significantly reduce the HCAMV rate, leading to a significant decline in the cost, morbidity, and mortality caused by neurosurgical procedures.

Abstract
AIM To investigate if adult cochlear implant (CI) recipients have received the recommended immunisations as compared to current guidelines and to report instances of meningitis within this population. METHODS Telephone interview of CI recipient's general practitioner (GP) surgeries for details regarding immunisations received. Subsequent reporting of immunisation rates of adult patients, under the care of the Northern Cochlear Implant Programme (NCIP) in New Zealand, when compared to the recommended guidelines from the Immunisation Advisory Centre (IMAC) and rates of meningitis of CI recipients are presented. RESULTS It is recommended to immunise against the most common organisms causing meningitis, Streptococcus pneumoniae and Haemophilus influenzae type b (HiB), as well as influenza. Data for 135 CI recipients over the last five years was complete. 14.8% of patients had received a full pneumococcal immunisation schedule. 11.9% had received a HiB immunisation and 62.2% an influenza vaccination. No patient had developed meningitis following CI insertion. CONCLUSION This paper highlights clear issues with the immunisation of adult CI recipients.

Estimating the cost-effectiveness of an infant 13-valent pneumococcal conjugate vaccine national immunization program in China. PLoS One 2018; 13:e0201245.

Abstract
Background The burden of pneumococcal disease in China is high, and a 13-valent pneumococcal conjugate vaccine (PCV13) recently received regulatory approval and is available to Chinese infants. PCV13 protects against the most prevalent serotypes causing invasive pneumococcal disease (IPD) in China, but will not provide full societal benefits until made broadly available through a national immunization program (NIP). Objective To estimate clinical and economic benefits of introducing PCV13 into a NIP in China using local cost estimates and accounting for variability in vaccine uptake and indirect (herd protection) effects. Methods We developed a population model to estimate the effect of PCV13 introduction in China. Modeled health states included meningitis, bacteremia, pneumonia (PNE), acute otitis media, death and sequelae, and no disease. Direct healthcare costs and disease incidence data for IPD and PNE were derived from the China Health Insurance and Research Association database; all other parameters were derived from published literature. We estimated total disease cases and associated costs, quality-adjusted life years (QALYs), and deaths for three scenarios from a Chinese Payer Perspective: (1) direct effects only, (2) direct+indirect effects for IPD only, and (3) direct+indirect effects for IPD and inpatient PNE. Results Scenario (1) resulted in 370.3 thousand QALYs gained and 12.8 thousand deaths avoided versus no vaccination. In scenarios (2) and (3), the PCV13 NIP gained 383.2 thousand and 3,580 thousand QALYs, and avoided 13.1 thousand and 147.5 thousand deaths versus no vaccination, respectively. In all three scenarios, the vaccination cost was offset by cost reductions from prevented disease yielding net costs of ¥29,362.32 million, ¥29,334.29 million, and ¥13,524.72 million, respectively. All resulting incremental cost-effectiveness ratios fell below a 2x China GDP cost-effectiveness threshold across a range of potential vaccine prices. Discussion Initiation of a PCV13 NIP in China incurs large upfront costs but is good value for money, and is likely to prevent substantial cases of disease among children and non-vaccinated individuals.

Modeling the cost-effectiveness of infant vaccination with pneumococcal conjugate vaccines in Germany. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2017; 18:273-292.

Abstract
BACKGROUND In 2009, the European Medicines Agency granted approval for two higher-valent pneumococcal conjugate vaccines. This study aims to evaluate the cost-effectiveness of universal infant (<2 years old) vaccination with a 13-valent pneumococcal conjugate vaccine (PCV13) in comparison with a 10-valent pneumococcal conjugate vaccine (PCV10) for the prevention of pneumococcal disease in Germany. METHODS A population-based Markov model was developed to estimate the impact of PCV13 and PCV10 on invasive pneumococcal disease (IPD), non-invasive pneumonia (PNE), and acute otitis media (AOM) over a time horizon of 50 years. The model included the effects of the historical vaccination scheme in infants as well as indirect herd effects and replacement disease. We used German epidemiological data to calculate episodes of IPD, PNE, and AOM, as well as direct and indirect effects of the vaccination. Parameter uncertainty was tested in univariate and probabilistic sensitivity analyses. RESULTS In the base-case analysis, the ICER of PCV13 versus PCV10 infant vaccination was EUR 9826 per quality-adjusted life-year (QALY) gained or EUR 5490 per life-year (LY) gained from the societal perspective and EUR 3368 per QALY gained or EUR 1882 per LY gained from the perspective of the German statutory health insurance. The results were particularly sensitive to the magnitude of indirect effects of both vaccines. CONCLUSIONS Universal infant vaccination with PCV13 is likely to be a cost-effective intervention compared with PCV10 within the German health care system, if additional net indirect effects of PCV13 vaccination are significant.

Abstract
OBJECTIVE To assess the frequency of external cerebrospinal fluid (CSF) drain-related CNS infections before and after implementation of a protocol for their prevention. DESIGN Quasi-experimental study, with comparison of incidence before and after the implementation of the intervention. SETTING AND PARTICIPANTS Bambino Gesù Children's Hospital in Rome, Italy. Children receiving an external cerebrospinal fluid drain from 1 January 2013 to 31 March 2015. MAIN OUTCOME MEASURES Drain-related infections. RESULTS Fifty-two patients were included in the study. Before protocol implementation, cumulative incidence was 14 per 100 drains. Incidence rate was 8/1,000 catheter-days. After protocol implementation, cumulative incidence and incidence rate were 6.7 per 100 drains and 4.6 per 1,000 catheter-days (p=0.61 and p=0.2 versus the pre-intervention period, respectively). Infected patients were significantly younger (median age: 16.5 days vs 13.4 months; p=0.026), had a significantly higher number of procedures (5 vs 1 procedure per patient; p <0.0001) and were most frequently affected by post-haemorrhagic hydrocephalus of premature newborns (50% vs 16.7%; p=0.039), compared to non-infected patients. CONCLUSIONS After protocol implementation, we observed a reduction of incidence of CSF drain-related infections, though the short post-intervention period limited the power of the study to detect a significant difference. Patients <1 year of age, with multiple interventions and post-haemorrhagic hydrocephalus had higher risk of CSF drain-related infections.

Abstract
Each of BALB/c mice was infected with 50 Angiostrongylus cantonensis larvae. One group of mice received an intraperitoneal injection of 50 μg 12D5 monoclonal antibody (mAb) against a 98 kDa antigen of adult worms at 10 days post-infection (dpi), with a booster injection of 25 μg at 12 dpi. Five mice from each group were sacrificed at 14 dpi for pathological examination and RNA extraction. The infiltration of eosinophils and severity of eosinophilic meningitis were reduced in 12D5 mAb-treated mice compared with the infected mice without 12D5 treatment. The levels of eotaxin mRNA expression in spleen significantly increased and the expression of the Th2-type cytokine IL-5 significantly decreased. However, the expression of IL-4 was not changed. 12D5 mAb can observably enhance the survival rate of infected mice and reduce symptoms of angiostrongyliasis. A. cantonensis infection is a major cause of eosinophilic meningoencephalitis. The results of this study could be helpful for the development of treatment of human angiostrongylosis.

Abstract
More than one hundred years have passed since Bier first succeeded in spinal anesthesia. Spinal anesthesia now spreads all over the world because it has many advantages. Spinal anesthesia requires both a simple technique and a small volume of drug, produces profound analgesia, and is devoid of systemic pharmacologic side effects. However, several complications after spinal anesthesia have been reported. Although some of them rarely occur, they cause serious consequences once they happen. Those include cardiac arrest, meningitis, intracranial subdural hematoma, spinal epidural hematoma and cauda equina syndrome. Patients should be informed in detail of the incidence, severity, and outcome of these complications, especially when alternative analgesic methods can be chosen. The prediction, early detection and prompt start of the treatment of the complications after spinal anesthesia are important to minimize the risk of adverse outcome.

Abstract
OBJECTIVE To develop a predictive model for rapid differential diagnosis of meningitis and meningococcal septicaemia to support public health decisions on chemoprophylaxis for contacts. METHODS Prospective study of suspected cases of acute meningitis and meningococcal septicaemia admitted to hospitals in the South West, West Midlands and London Regions of England from July 2008 to June 2009. Epidemiological, clinical and laboratory variables on admission were recorded. Logistic regression was used to derive a predictive model. RESULTS Of the 719 suspect cases reported, 385 confirmed cases were included in analysis. Peripheral blood polymorphonuclear count of >16 × 10(9)/l, serum C-reactive protein of >100 mg/l and haemorrhagic rash were strongly and independently associated with diagnosis of bacterial meningitis and meningococcal septicaemia. Using a simple scoring system, the presence of any one of these factors gave a probability of >95% in predicting the final diagnosis. CONCLUSION We have developed a model using laboratory and clinical factors, but not dependent on availability of CSF, for differentiating acute bacterial from viral meningitis within a few hours of admission to hospital. This scoring system is recommended in public health management of suspected cases of meningitis and meningococcal septicaemia to inform decisions on chemoprophylaxis.

Abstract
OBJECTIVE To determine the meningitis and influenza vaccination coverage rates among Saudi military personnel in Riyadh (Central Military Region [CMR]), Kingdom of Saudi Arabia, (KSA) and the socio-demographic factors that influence vaccination. METHODS This cross-sectional descriptive study was carried out on a sample of 2286 military personnel from different army forces and different military ranks in CMR in KSA selected by a 2-stage stratified random sampling technique. A self-administered questionnaire designed for the National Military Health Survey was used with a section added for assessment of vaccination status. Data collection was carried out from May to August 2009. RESULTS The response rate was 97.6%. The vaccination coverage was higher for meningitis (51.7%) compared with influenza (17.8%). A high percentage lacked awareness of their vaccination status. Vaccination rates were higher in the Land Forces, and increased with more years of education, and lower crowding index. CONCLUSION The proportion of vaccination coverage among military personnel in CMR of KSA is low, especially for influenza, along with their awareness of their vaccination status. A vaccination program that includes awareness promotion of vaccine-preventable diseases is recommended, with changes in the policies to mandate vaccination against meningitis and influenza.

Abstract
Although the annual incidence of bacterial meningitis in the United States is declining, it remains a medical emer- gency with a potential for high morbidity and mortality. Clinical signs and symptoms are unreliable in distinguishing bacterial meningitis from the more common forms of aseptic meningitis; therefore, a lumbar puncture with cerebro- spinal fluid analysis is recommended. Empiric antimicrobial therapy based on age and risk factors must be started promptly in patients with bacterial meningitis. Empiric therapy should not be delayed, even if a lumbar puncture cannot be performed because results of a computed tomography scan are pending or because the patient is awaiting transfer. Concomitant therapy with dexamethasone initiated before or at the time of antimicrobial therapy has been demonstrated to improve morbidity and mortality in adults with Streptococcus pneumoniae infection. Within the United States, almost 30 percent of strains of pneumococci, the most common etiologic agent of bacterial meningitis, are not susceptible to penicillin. Among adults in developed countries, the mortality rate from bacterial meningitis is 21 percent. However, the use of conjugate vaccines has reduced the incidence of bacterial meningitis in children and adults.

Abstract
The overall incidence of bacterial meningitis has decreased due to numerous factors, but substantial disease burden remains from both bacterial and nonbacterial meningitis with or without accompanying encephalitis. Recently developed or validated surrogate markers of disease--including polymerase chain reaction, inflammatory markers, and magnetic resonance imaging--enhance diagnostic utility. Current guidelines and studies have modified the use of particular antibiotics and expanded the role of adjunctive steroid therapy in selected patients. This review provides an update to the general diagnostic evaluation, epidemiology, pathophysiology, clinical assessment, antibiotic treatment, adjunctive therapy, prognosis, and prevention of meningitis and encephalitis in the adolescent population.

Abstract
OBJECTIVE To discuss the perioperative complications of 1396 cases (1402 ears) with cochlear implantation (CI), and to supply clinical experience for risk reduction in the perioperative period. METHOD All patients were profound sensorineural deafness, with 1379 prelingual cases and 17 postlingual cases. (1) Preoperative examinations: audiology,imaging studies, evaluation of physical and intellectual development. (2) Perioperative complications. RESULT (1) Perioperative complications: transitory postoperative facial palsy in 4 cases; external auditory canal and membrana tympani injury in 14 cases; gusher in 91 cases; cerebral dura mater injury in 2 cases; problems of electrodes in 31 cases including 2 of electrodes inserted into inner auditory canal and 1 into scala vestibuli, 28 of electrodes squire in the cochlea; transient vertigo in 231 cases; scalp hematoma in 39 cases. (2) Systematic postoperative complications: fever ( >38 degrees C) in 21 cases; acute gastritis in 27 cases; bronchitis and pneumonia in 5 cases; laryngotracheitis in 9 cases. (3) Other complications: artificial cochlear exchange due to computer trouble during operation. CONCLUSION (1) CI is a relatively safe surgical procedure, but risks still persist during perioperative period including postoperative meningitis, facial nerve and chorda tympani nerve injury,and so on. (2) To ensure successful operation, perioperative managements should be standardized.

Early recognition of meningitis and septicaemia. THE JOURNAL OF FAMILY HEALTH CARE 2010; 20:6-8. [PMID: 20397549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/29/2023]
Abstract
Meningitis is a disease feared by parents and health professionals alike. The rapid onset and progression of the disease and potentially lethal outcome makes it vital to diagnose the disease early, but this can be difficult. This is particularly the case during the current swine flu pandemic, where concerns have been raised that cases of meningitis may be missed due to a misdiagnosis of swine flu. Early symptoms of meningitis and septicaemia often resemble viral illnesses such as influenza, making the condition difficult to diagnose. Classic symptoms (the ones that many health professionals and lay people most commonly associate with meningitis), such as a nonblanching rash and a stiff neck, are often late symptoms of the disease and neck stiffness is rarer in infants and young children. The presence of ear or upper respiratory tract infections does not necessarily exclude a diagnosis of meningitis. The emphasis should therefore be on regular, close monitoring of an ill child and assessment of the vital signs. Awareness of the recognised "red flag" symptoms of septicaemia--cold hands and feet, limb pain and pale or mottled skin--could also aid earlier diagnosis and hence potentially improve prognosis.

Abstract
All the congenital infections and most of the natal and postnatally acquired infections of man are associated with disease of the central nervous system and long-term sequelae in the survivors. The most important perinatal pathogens in this regard are group B streptococcus, Escherichia coli and other coliform bacteria, cytomegalovirus, Toxoplasma gondii and herpes simplex virus. All these agents are the subject of active and, in some instances, promising investigation. The strategies for prevention are discussed here. Recent clinical trails of two cytomegalovirus vaccines (Towne 125 and AD 169) are considered in detail.

Abstract
Abstract
OBJECTIVE
Although prophylactic antibiotics have been shown by randomized clinical trials (RCTs) to help prevent deep infection after craniotomies, recent reports have suggested that antibiotics are not effective in preventing postcraniotomy meningitis.
METHODS
Data on meningitis as an end point from RCTs on prophylactic antibiotics for craniotomies were pooled in a random-effects meta-analysis.
RESULTS
Six prospective randomized trials or trial subgroups enrolling 1729 patients or operations were identified. Antibiotics reduced postoperative infection rates in five of the six RCTs; no trial individually showed a statistically significant benefit from antibiotics. The pooled odds ratio for meningitis with antibiotic treatment in the six RCTs was 0.43 (95% confidence interval, 0.20–0.92; P = 0.03). Subgroup analyses showed no detectable difference in antibiotic efficacy if antibiotics, with or without gram- negative coverage, were used or if the trial was single or double blinded. A sensitivity analysis showed modest dependence of the results of the analysis on the specific definition of postoperative meningitis used in interpreting trial results.
CONCLUSION
Prophylactic antibiotics administered before craniotomy reduce rates of postoperative meningitis by approximately one-half, a statistically and clinically significant benefit.

Abstract
Abstract
Central nervous system (CNS) prophylaxis has led to a significant improvement in the outcome of patients with acute lymphocytic leukemia (ALL). Liposomal cytarabine (Enzon Pharmaceuticals, Piscataway, NJ; Skye Pharma, San Diego, CA), an intrathecal (IT) preparation of cytarabine with a prolonged half-life, has been shown to be safe and effective in the treatment of neoplastic meningitis. Liposomal cytarabine was given for CNS prophylaxis to 31 patients with newly diagnosed ALL. All patients were treated concurrently with hyper-CVAD chemotherapy (fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone) including high-dose methotrexate (MTX) and cytarabine on alternating courses. Liposomal cytarabine 50 mg was given intrathecally on days 2 and 15 of hyper-CVAD and day 10 of high-dose MTX and cytarabine courses until completion of either 3, 6, or 10 IT treatments, depending on risk for CNS disease. Five patients (16%) experienced serious unexpected neurotoxicity, including seizures, papilledema, cauda equina syndrome (n = 2), and encephalitis after a median of 4 IT administrations of liposomal cytarabine. Toxicities usually manifested after the MTX and cytarabine courses. One patient died with progressive encephalitis. After a median follow-up of 7 months, no isolated CNS relapses have been observed. Liposomal cytarabine given via intrathecal route concomitantly with systemic chemotherapy that crosses the blood-brain barrier such as high-dose MTX and cytarabine can result in significant neurotoxicity.

Abstract
Pneumonia, meningitis, and sepsis place a significant economic burden on health care systems, particularly in developing countries. This study estimates treatment costs for these diseases in health facilities in the Northern Areas of Pakistan. Health facility resources are organized by categories--including salaries, capital costs, utilities, overhead, maintenance and supplies--and quantified using activity-based costing (ABC) techniques. The average cost of treatment for an outpatient case of child pneumonia is dollar 13.44. For hospitalized care, the health system spent an average of dollar 71 per episode for pneumonia, dollar 235 for severe pneumonia, and dollar 2,043 for meningitis. These costs provide important background information for the potential introduction of the conjugate Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae vaccines in Pakistan.

Abstract
Invasive disease due to Neisseria meningitidis continues to cause debility and death worldwide in otherwise healthy individuals. Disease epidemiology varies globally, but most cases are due to serogroups A, B, C, W-135 or Y. MenactraTM (MCV-4), a quadrivalent, meningococcal diphtheria-conjugate vaccine against serogroups A, C, Y, and W-135, was licensed in the USA for individuals 11-55 years of age. Published results of clinical trials demonstrated robust immune responses that correlate with indicators of protection. MCV-4-induced antibody persist for up to 3 years after administration and anamnestic responses to revaccination. The vaccine was well tolerated; the most common reactions were transient, mild injection-site reactions and headache. MCV-4 should provide significant clinical benefits in the future.

Abstract
BACKGROUND The association between complement deficiencies and the increased risk for meningococcal infections and bacterial meningitis is well described and most striking in patients with deficiencies of one of the late complement components, i.e., C5-C9. CASE REPORT In the presented study the first case of a patient with combined-heterozygous deficiency of complement C7 is described. The defect led to a strongly reduced but still measurable production of C7. However, the low concentration of C7 was not protective against recurrent bacterial meningitis. CONCLUSION The reported case illustrates once again the necessity of complement analysis in patients with meningitis. Not only patients with undetectable complement activity but also those with strongly reduced but still measurable complement function should be analyzed for a possible complement deficiency.

Abstract
OBJECTIVE To explore the common complications related to acoustic neuromas and to search methods for preventing from them. METHODS One hundred and five patients with acoustic neuromas underwent 110 operations with the retrosigmoid approach, middle cranial fossa approach and labyrinth approach. All cases were followed up more than 1 month after surgery. RESULTS Of 110 cases, the most frequent complication was hearing disability which occurred in 95 cases (95/110, 86.4%). and the facial paralysis was in 63.6% (70/110) after one month. Other complications were cerebrospinal fluid fistulas (CSF, 12.7%, 14/110) , intracranial hematoma (5.5%, 6/110), cranial nerve palsies (4.5%, 5/110), meningitis (3.6%, 4/110), tetraparesis (3.6%, 4/110), balance disturbance (1.8%, 2/110), hemiparalysis and anepia (0.9%, 1/110). Effective stopping bleeding during operation and controlling blood pressure after operation, as well as keeping effective sedation in 24 hours after operation were the important ways to prevent from intracranial hematoma The haemorrhage often accrued in 48 hours post-operation. CSF in this series was another common complication in acoustic neuroma surgery. Ten cases with CSF subcutaneous retro-auricular had been successfully controlled by conservative treatment. Of 4 cases with rhinorrhea CSF, 3 of them were required surgical management, another one got self-cure by bed rest. The ventricular drainage pro-operation was the most important procedure for drawdown the hypsi-cranium pressure. CONCLUSIONS The key factors to avoid the complications include mastering the anatomy of different surgical approach, how much of the tumor size, surgical experience and preoperative evaluation of patients' imaging information and other clinical data.
