Meningitis following spinal anesthesia: 6 cases in 5 years.

We describe 6 cases of meningitis after spinal anesthesia associated with a single anesthesiologist over the course of 5 years. The earliest case occurred in 2000, and the other 5 cases occurred over the course of 14 months in 2004-2005. The case identified in 2000 was culture-positive for Streptococcus salivarius. The other 5 cases were culture-negative for this organism but in 2 cases, the cerebrospinal fluid was found to be positive for bacterial DNA that was identified as belonging to S. salivarius by sequencing of the 16S rRNA gene. The association with a single anesthesiologist and a single hospital during a relatively short interval, however, lead us to believe that these occurrences are part of a series associated with possible violations of aseptic technique.

The Israeli public health response to wild poliovirus importation

In 2013, a silent wild poliovirus type 1 importation and sustained transmission event occurred in southern Israel. With the aim of preventing clinical poliomyelitis and ensuring virus re-elimination, the public health response to the importation event included intensification of clinical and environmental surveillance activities, enhancement of vaccine coverage, and supplemental immunisation with a bivalent oral polio vaccine against wild poliovirus types 1 and 3. A national campaign launched in August, 2013, resulted in vaccination of 943,587 children younger than 10 years (79% of the eligible target population). Expanded environmental surveillance (roughly 80% population coverage) documented a gradual disappearance of wild poliovirus type 1 in the country from September, 2013, to April, 2014. No paralytic poliomyelitis case was detected. A prompt extensive and coordinated national public health response, implemented on the basis of evidence-based decision making, successfully contained this serious importation and sustained transmission event of wild poliovirus to Israel. On April 28, 2015, WHO officially declared Israel as a polio-free country.

Preventing mumps outbreaks in confined settings: comprehensive ring vaccination as a containment strategy.

Even among vaccinated cohorts, prevention and control of mumps outbreaks remain a challenge, owing to sub-optimal population immunity. This is especially true in confined settings, where a single case could be the index for an imminent outbreak. Efficacy of post-exposure prophylaxis has not been demonstrated, while early identification of mumps and comprehensive vaccination of populations in confined settings during outbreaks may enable containment of mumps and disrupt further spread. However, we are not aware of official international guidelines concerning vaccination of exposed individuals during an outbreak, especially in a confined setting. In this article we present our experience with mumps containment during outbreaks through vaccination campaigns in the Israeli civilian and military populations and discuss lessons for containment efforts in other settings. Our analysis shows that a comprehensive ring vaccination should be considered in any case of mumps in confined settings.

Factors affecting Varicella vaccine uptake among children 1-17 years old in the Haifa District in 2007

The Israeli National Vaccination Program (INVP) is aimed mainly at the pediatric age group. Till 2008 the program did not include routine administration of vaccine against Varicella (chickenpox).For the past 7 years, however, vaccine against Varicella has been available to the public and subsidized through the health maintenance organizations (HMOs). On the eve of probable introduction of the Varicella Zoster Vaccine (VZ-V) into the INVP a study was conducted to examine factors postulated to be of importance in vaccination uptake. These factors can be assessed while the vaccine is only administered through active choice, as opposed to administration by default as part of INVP. The study group comprised the communities in the District of Haifa. The aim of the study was to assess vaccination rates and contributing factors in the decision to vaccinate or not vaccinate against VZ. The study showed that uptake of VZ-V was in correlation with: 1. Population group (i.e. religious denomination) - Jews were more likely to vaccinate (OR=3.88). 2. Level of education - parents with higher level of education were more likely to vaccinate. (OR=1.91). 3. Level of religious observance - non-observant parents were more likely to vaccinate (OR=2.7) 4. Complementary insurance (reimbursement of cost) - parents with complementary insurance were more likely to vaccinate (OR=3.41). 5. A physicians recommendation to vaccinate - when a physician recommendation was given for vaccination the likelihood of vaccination was increased (OR=2.94).

Trust and the demand for autonomy may explain the low rates of immunizations among nurses

Rates of vaccinations of healthcare workers with recommended vaccines are generally low in the developed countries. Our goals were to identify attitudes associated with self-reported vaccinations against pertussis and seasonal influenza among Israeli nurses in Mother and Child Healthcare Centers (MCHC) in the Haifa District. Over 100 nurses answered a self-administered questionnaire. Forty two percent of the nurses reported receiving the pertussis vaccine in the last five years and 44% reported receiving the influenza vaccine during the previous year. Attitudes toward the importance of vaccinating nurses, trust in the public health authorities and demand for autonomy were associated with receiving the pertussis vaccine. Attitudes toward the importance of vaccinating nurses and trust were associated with receiving the influenza vaccine in a bivariant analysis. However, in the logistic regression models only attitudes toward the importance of vaccinating nurses were associated with vaccinations [odds ratio (OR)- 3.66, 95% confidence interval (CI)- 1.4–9.6 for pertussis and OR- 4.53, CI-1.6–13.0 for influenza]. Jewish nurses reported more often receiving the influenza vaccine compared with the Arab nurses, whereas there was no difference between them in receiving the pertussis vaccine. Low levels of positive attitudes toward the importance of vaccinating nurses may inhibit nurses in MCHC from receiving vaccines. The demand for autonomy and low levels of trust may, in part, form these low levels of positive attitudes toward the importance of vaccinating nurses.

Intent-to-Adhere and Adherence to Malaria Prevention Recommendations in Two Travel Clinics

Malaria infects 30,000 travelers annually worldwide. At greatest risk are those who travel for long duration. Prevention of malaria includes chemoprophylaxis. This prospective study on 121 travelers who visited two travel clinics shows that adherence to prophylactic treatment was low, especially in long duration trips, and that adherence rate could be predicted by the much more available intent-to-adhere rate.

Variables correlated with elderly referral from nursing homes to general hospitals.

BackgroundReferring patients from nursing homes to general hospitals exposes them to nosocomial diseases, and may result in the development of a broad spectrum of physical, mental and social damages. Therefore, minimizing the referring of nursing home patients to hospitals is an important factor for keeping the elderly healthy and minimizing health expenditures. In this study we examined the variables related to the referral rates from nursing homes to general hospitals and the relationship between the referral and the mortality rates among the elderly who live in nursing homes in the Haifa Sub-district.MethodsThirty-two nursing homes were included in a cross-sectional study. All medical directors and head nurses were interviewed using a structured questionnaire between November 2006 and October 2007. Statistical analysis, including the ANOVA and the nonparametric Spearman tests, were employed to determine the factors that influence referral rates and the correlation between referral rates and mortality rates.ResultsThe referral rate ranged between 18 and 222 per 100 financed elderly in a single year. In the multivariate analysis, the absence of a physician from the nursing home at the time of the referral to general hospitals was the only significant variable related to referral rates. No significant relationships were found between referral rates and mortality rates.ConclusionsAbsence of a significant relationship between referral rates and mortality rates may indicate that high referral rates do not necessarily protect the elderly from death. Therefore, any recommendations issued by the Ministry of Health (MOH) should emphasize in-house treatment rather than hospitalization. Clear instructions on referral from nursing homes to general hospitals need to be constructed by the MOH. The MOH should increase the presence of physicians in the nursing homes, especially, when the need to refer a patient arises. Further quantitative and epidemiologic studies should be conducted in order to, more fully and reliably, create guidelines for policy recommendations.

Malaria in a seaport worker in Haifa.

A healthy port worker who had traveled to Azerbaijan 2 years previously was diagnosed with vivax malaria. This is most likely a case of seaport malaria, which has been reported only four times previously. The importance of obtaining a proper occupational, as well as travel, history when evaluating febrile patients is emphasized.
